Practitioners and professionals.

The healthcare workforce comprises a wide variety of professions and occupations who provide some type of healthcare service, including such direct care practitioners as physicians, respiratory therapists, nurses, surgeons, dentists, physical and behavior therapists, as well as allied health professionals such as phlebotomists, medical laboratory scientists, dieticians, and social workers. They often work in hospitals, healthcare centres and other service delivery points, but also in academic training, research, and administration. Some provide care and treatment services for patients in private homes. Many countries have a large number of community health workers who work outside formal healthcare institutions. Managers of healthcare services, health information technicians, and other assistive personnel and support workers are also considered a vital part of health care teams.  Healthcare practitioners are commonly grouped into health professions. Within each field of expertise, practitioners are often classified according to skill level and skill specialization. “Health professionals” are highly skilled workers, in professions that usually require extensive knowledge including university-level study leading to the award of a first degree or higher qualification. This category includes physicians, physician assistants, dentists, midwives, radiographers, registered nurses, pharmacists, physiotherapists, optometrists, operating department practitioners and others. Allied health professionals, also referred to as "health associate professionals" in the International Standard Classification of Occupations, support implementation of health care, treatment and referral plans usually established by medical, nursing, respiratory care, and other health professionals, and usually require formal qualifications to practice their profession. In addition, unlicensed assistive personnel assist with providing health care services as permitted.  Another way to categorize healthcare practitioners is according to the sub-field in which they practice, such as mental health care, pregnancy and childbirth care, surgical care, rehabilitation care, or public health.

Mental health practitioners.

A mental health practitioner is a health worker who offers services to improve the mental health of individuals or treat mental illness. These include psychiatrists, clinical psychologists, occupational therapists, clinical social workers, psychiatric-mental health nurse practitioners, marriage and family therapists, mental health counselors, as well as other health professionals and allied health professions. These health care providers often deal with the same illnesses, disorders, conditions, and issues; however, their scope of practice often differs. The most significant difference across categories of mental health practitioners is education and training.

Maternal and newborn health practitioners.

A maternal and newborn health practitioner is a health worker who deals with the care of women and their children before, during and after pregnancy and childbirth. Such health practitioners include obstetricians, midwives, obstetrical nurses and many others. One of the main differences between these professions is in the training and authority to provide surgical services and other life-saving interventions. In some developing countries, traditional birth attendants, or traditional midwives, are the primary source of pregnancy and childbirth care for many women and families, although they are not certified or licensed.

Geriatric care practitioners.

A geriatric care practitioner plans and coordinates the care of the elderly and/or disabled to promote their health, improve their quality of life, and maintain their independence for as long as possible. They include geriatricians, adult-gerontology nurse practitioners, clinical nurse specialists, geriatric clinical pharmacists, geriatric nurses, geriatric care managers, geriatric aides, Nursing aides, Caregivers and others who focus on the health and psychological care needs of older adults.

Surgical practitioners.

A surgical practitioner is a healthcare professional who specializes in the planning and delivery of a patient's perioperative care, including during the anaesthetic, surgical and recovery stages. They may include general and specialist surgeons, surgical PAs, surgeon's assistant, assistant surgeon, surgical assistant, anesthesiologists, anesthesiologist assistant, nurse anesthetists, surgical nurses, clinical officers, operating department practitioners, anaesthetic technicians, perioperative nursing, surgical technologists, and others.

Rehabilitation care practitioners.

A rehabilitation care practitioner is a health worker who provides care and treatment which aims to enhance and restore functional ability and quality of life to those with physical impairments or disabilities. These include physiatrists, rehabilitation nurses, clinical nurse specialists, nurse practitioners, physiotherapists, orthotists, prosthetists, occupational therapists, recreational therapists, audiologists, speech and language pathologists, respiratory therapists, rehabilitation counsellors, physical rehabilitation therapists, athletic trainers, physiotherapy technicians, orthotic technicians, prosthetic technicians, personal care assistants, and others.

Eye care practitioners.

Care and treatment for the eye and the adnexa may be delivered by ophthalmologists specializing in surgical/medical care, or optometrists specializing in refractive management and medical/therapeutic care.

Medical diagnosis providers.

Medical diagnosis providers are health workers responsible for the process of determining which disease or condition explains a person's symptoms and signs. It is most often referred to as diagnosis with the medical context being implicit. This usually involves a team of healthcare providers in various diagnostic units. These include radiographers, radiologists, Sonographers, medical laboratory scientists, pathologists, and related professionals.

Oral care practitioners.

A dental care practitioner is a health worker who provides care and treatment to promote and restore oral health. These include dentists and dental surgeons, dental assistants, dental auxiliaries, dental hygienists, dental nurses, dental technicians, dental therapists or oral health therapists, and related professionals.

Foot care practitioners.

Care and treatment for the foot, ankle, and lower leg may be delivered by podiatrists, chiropodists, pedorthists, foot health practitioners, podiatric medical assistants, podiatric nurse and others.

Public health practitioners.

A public health practitioner focuses on improving health among individuals, families and communities through the prevention and treatment of diseases and injuries, surveillance of cases, and promotion of healthy behaviors. This category includes community and preventive medicine specialists, public health nurses, clinical nurse specialists, dietitians, environmental health officers, paramedics, epidemiologists, health inspectors, Public Health Dentists, and others.

Alternative medicine practitioners.

In many societies, practitioners of alternative medicine have contact with a significant number of people, either as integrated within or remaining outside the formal health care system. These include practitioners in acupuncture, Ayurveda, herbalism, homeopathy, naturopathy, Reiki, Shamballa Reiki energy healing, Siddha medicine, traditional Chinese medicine, traditional Korean medicine, Unani, and Yoga. In some countries such as Canada, chiropractors and osteopaths (not to be confused with doctors of osteopathic medicine in the United States) are considered alternative medicine practitioners.

Practice conditions and regulations.

Shortages of health professionals.

Many jurisdictions report shortfalls in the number of trained health human resources to meet population health needs and/or service delivery targets, especially in medically underserved areas. For example, in the United States, the 2010 federal budget invested $330 million to increase the number of doctors, nurses, and dentists practicing in areas of the country experiencing shortages of trained health professionals. The Budget expands loan repayment programs for physicians, nurses, and dentists who agree to practice in medically underserved areas. This funding will enhance the capacity of nursing schools to increase the number of nurses. It will also allow states to increase access to oral health care through dental workforce development grants. The Budget's new resources will sustain the expansion of the health care workforce funded in the Recovery Act. There were 15.7 million health care professionals in the US as of 2011.  In Canada, the 2011 federal budget announced a Canada Student Loan forgiveness program to encourage and support new family physicians, nurse practitioners and nurses to practice in underserved rural or remote communities of the country, including communities that provide health services to First Nations and Inuit populations.  In Uganda, the Ministry of Health reports that as many as 50% of staffing positions for health workers in rural and underserved areas remain vacant. As of early 2011, the Ministry was conducting research and costing analyses to determine the most appropriate attraction and retention packages for medical officers, nursing officers, pharmacists, and laboratory technicians in the country's rural areas.  At the international level, the World Health Organization estimates a shortage of almost 4.3 million doctors, midwives, nurses, and support workers worldwide to meet target coverage levels of essential primary health care interventions. The shortage is reported most severe in 57 of the poorest countries, especially in sub-Saharan Africa.

Occupational hazards.

The healthcare workforce faces unique health and safety challenges and is recognized by the National Institute for Occupational Safety and Health (NIOSH) as a priority industry sector in the National Occupational Research Agenda (NORA) to identify and provide intervention strategies regarding occupational health and safety issues. Occupational stress and occupational burnout are highly prevalent among health professionals. Some studies suggest that workplace stress is pervasive in the health care industry because of inadequate staffing levels, long work hours, exposure to infectious diseases and hazardous substances leading to illness or death, and in some countries threat of malpractice litigation. Other stressors include the emotional labor of caring for ill people and high patient loads. The consequences of this stress can include substance abuse, suicide, major depressive disorder, and anxiety, all of which occur at higher rates in health professionals than the general working population. Elevated levels of stress are also linked to high rates of burnout, absenteeism and diagnostic errors, and reduced rates of patient satisfaction. In Canada, a national report ("Canada's Health Care Providers") also indicated higher rates of absenteeism due to illness or disability among health care workers compared to the rest of the working population, although those working in health care reported similar levels of good health and fewer reports of being injured at work. There is some evidence that cognitive-behavioral therapy, relaxation training and therapy (including meditation and massage), and modifying schedules can reduce stress and burnout among multiple sectors of health care providers. Research is ongoing in this area, especially with regards to physicians, whose occupational stress and burnout is less researched compared to other health professions.  Exposure to respiratory infectious diseases like tuberculosis (caused by "Mycobacterium tuberculosis") and influenza can be reduced with the use of respirators; this exposure is a significant occupational hazard for health care professionals. Exposure to dangerous chemicals, including chemotherapy drugs, is another potential occupational risk. These drugs can cause cancer and other health conditions. Healthcare workers are also at risk for diseases that are contracted through extended contact with a patient, including scabies. Health professionals are also at risk for contracting blood-borne diseases like hepatitis B, hepatitis C, and HIV/AIDS through needlestick injuries or contact with bodily fluids. This risk can be mitigated with vaccination when there is a vaccine available, like with hepatitis B. In epidemic situations, such as the 2014-2016 West African Ebola virus epidemic or the 2003 SARS outbreak, healthcare workers are at even greater risk, and were disproportionately affected in both the Ebola and SARS outbreaks. In general, appropriate personal protective equipment (PPE) is the first-line mode of protection for healthcare workers from infectious diseases. For it to be effective against highly contagious diseases, personal protective equipment must be watertight and prevent the skin and mucous membranes from contacting infectious material. Different levels of personal protective equipment created to unique standards are used in situations where the risk of infection is different. Practices such as triple gloving and multiple respirators do not provide a higher level of protection and present a burden to the worker, who is additionally at increased risk of exposure when removing the PPE. Compliance with appropriate personal protective equipment rules may be difficult in certain situations, such as tropical environments or low-resource settings. A 2016 Cochrane systematic review found low-quality evidence that using more breathable fabric in PPE, double gloving, and active training reduce the risk of contamination.  Female health care workers may face specific types of workplace-related health conditions and stress. According to the World Health Organization, women predominate in the formal health workforce in many countries and are prone to musculoskeletal injury (caused by physically demanding job tasks such as lifting and moving patients) and burnout. Female health workers are exposed to hazardous drugs and chemicals in the workplace which may cause adverse reproductive outcomes such as spontaneous abortion and congenital malformations. In some contexts, female health workers are also subject to gender-based violence from coworkers and patients.  Healthcare workers are at higher risk of on-the-job injury due to violence. Drunk, confused, and hostile patients and visitors are a continual threat to providers attempting to treat patients. Frequently, assault and violence in a healthcare setting goes unreported and is wrongly assumed to be part of the job. Violent incidents typically occur during one-on-one care; being alone with patients increases healthcare workers' risk of assault. In the United States, healthcare workers suffer 2⁄3 of nonfatal workplace violence incidents. Psychiatric units represent the highest proportion of violent incidents, at 40%; they are followed by geriatric units (20%) and the emergency department (10%). Workplace violence can also cause psychological trauma.  Slips, trips, and falls are the second-most common cause of worker's compensation claims in the US and cause 21% of work absences due to injury. These injuries most commonly result in strains and sprains; women, those older than 45, and those who have been working less than a year in a healthcare setting are at the highest risk.  Health care professionals are also likely to experience sleep deprivation due to their jobs. Many health care professionals are on a shift work schedule, and therefore experience misalignment of their work schedule and their circadian rhythm. In 2007, 32% of healthcare workers were found to get fewer than 6 hours of sleep a night. Sleep deprivation also predisposes healthcare professionals to make mistakes that may potentially endanger a patient.  An epidemiological study published in 2018 examined the hearing status of noise-exposed health care and social assistance (HSA) workers sector to estimate and compare the prevalence of hearing loss by subsector within the sector. Most of the HSA subsector prevalence estimates ranged from 14% to 18%, but the Medical and Diagnostic Laboratories subsector had 31% prevalence and the Offices of All Other Miscellaneous Health Practitioners had a 24% prevalence. The Child Day Care Services subsector also had a 52% higher risk than the reference industry.

Regulation and registration of professionals.

Practicing without a license that is valid and current is typically illegal. In most jurisdictions, the provision of health care services is regulated by the government. Individuals found to be providing medical, nursing or other professional services without the appropriate certification or license may face sanctions and criminal charges leading to a prison term. The number of professions subject to regulation, requisites for individuals to receive professional licensure, and nature of sanctions that can be imposed for failure to comply vary across jurisdictions.  In the United States, under Michigan state laws, an individual is guilty of a felony if identified as practicing in the health profession without a valid personal license or registration. Health professionals can also be imprisoned if found guilty of practicing beyond the limits allowed by their licences and registration. The state laws define the scope of practice for medicine, nursing, and a number of allied health professions. In Florida, practicing medicine without the appropriate license is a crime classified as a third degree felony, which may give imprisonment up to five years. Practicing a health care profession without a license which results in serious bodily injury classifies as a second degree felony, providing up to 15 years' imprisonment.  In the United Kingdom, healthcare professionals are regulated by the state; the UK Health and Care Professions Council (HCPC) protects the 'title' of each profession it regulates. For example, it is illegal for someone to call himself an Occupational Therapist or Radiographer if they are not on the register held by the HCPC.

Best practices for employing health care personnel.

Tuberculosis (TB) screening, testing, and education.

Based on recommendations from The Center for Disease Control and Prevention (CDC) for TB screening and testing the following best practices should be followed when hiring and employing Health Care Personnel.

Initial hiring process.

When hiring Health Care Personnel, the applicant should complete the following:

Recommended testing procedures.

The CDC recommends either a blood test, also known as an interferon-gamma release assay (IGRA), or a skin test, also known as a Mantoux tuberculin skin test (TST). It is not the intention of this article to explore the protocol of carrying out a proper TB test. A TB blood test for baseline testing does not require two-step testing. If the skin test method is used to test HCP upon hire, then two-step testing should be used. A one-step test is not recommended.

Two-step testing.

The CDC has outlined further specifics on recommended testing for several scenarios. In summary:  According to these recommended testing guidelines any two negative TST results within 12 months of each other constitute a two-step TST.

A health professional (or healthcare professional) may provide health care treatment and advice based on formal training and experience. The field includes those who work as a physician, surgeon, physician assistants, nurse, physiotherapist, dentist, midwife, psychologist, psychiatrist, or pharmacist or who perform services in allied health professions. A health professional may also be a public health or community health practitioner.

Zdravotník je člověk s úplným středním, vyšším nebo vysokoškolským vzděláním. Zdravotníkem můžou ale také být lidé, kteří mají různé kurzy, akreditované Ministerstvem školstvní mládeže a tělovýchovy. Tyto kurzy jsou pak uváděny např pod názvy: ZZA – zdravotník zotavovacích akcí, který může jezdit s dětmi nebo jinými osobami na letní tábory, ozdravné pobyty, ale pozor, tato osoba není vystudována, má pouze absolvován kurz v rozsahu minimálně 40 hodin. Dále potom kurz ZNZZ – základní norma zdravotnických znalostí. Vystudovaní zdravotníci poté mohou pracovat na různých odděleních nemocnic, na záchranných službách, horských službách, či jiných ústavech nebo záchranných složkách.


History.

The Prix de Rome was initially created for painters and sculptors in 1663 in France, during the reign of Louis XIV. It was an annual bursary for promising artists having proved their talents by completing a very difficult elimination contest. To succeed, a student had to create a sketch on an assigned topic while isolated in a closed booth with no reference material to draw on. The prize, organised by the Académie Royale de Peinture et de Sculpture (Royal Academy of Painting and Sculpture), was open to their students. From 1666, the award winner could win a stay of three to five years at the Palazzo Mancini in Rome at the expense of the King of France. In 1720, the Académie Royale d’Architecture began a prize in architecture. Six painters, four sculptors, and two architects would be sent to the French Academy in Rome founded by Jean-Baptiste Colbert from 1666.  Expanded after 140 years into five categories, the contest started in 1663 as two categories: painting and sculpture. Architecture was added in 1720. In 1803, music was added, and after 1804 there was a "prix" for engraving as well. The primary winner took the "First Grand Prize" (called the "agréé"), and the "Second Prizes" were awarded to the runners-up.  In 1803, Napoleon Bonaparte moved the French Academy in Rome to the Villa Medici, with the intention of preserving an institution once threatened by the French Revolution. At first, the villa and its gardens were in a sad state, and they had to be renovated in order to house the winners of the Prix de Rome. In this way, he hoped to retain for young French artists the opportunity to see and copy the masterpieces of antiquity and the Renaissance.  Jacques-Louis David, having failed to win the prize three years in a row, considered suicide. Édouard Manet, Edgar Degas, Ernest Chausson, and Maurice Ravel attempted the Prix de Rome but did not gain recognition. Ravel tried a total of five times to win the prize, and the last failed attempt in 1905 was so controversial that it led to a complete reorganization of the administration at the Paris Conservatory.  During World War II (1939–45), the prize winners were accommodated in the Villa Paradiso in Nice. The Prix de Rome was abolished in 1968 by André Malraux, who was Minister of Culture at the time. Since then, a number of contests have been created, and the academies, together with the Institut de France, were merged by the State and the Minister of Culture. Selected residents now have an opportunity for study during an 18-month (sometimes 2-year) stay at The Academy of France in Rome, which is accommodated in the Villa Medici.  The heyday of the Prix de Rome was during the late eighteenth and early nineteenth centuries. It was later imitated by the Prix Abd-el-Tif and the Villa Abd-el-Tif in Algiers, 1907–1961, and later Prix d'Indochine including a bursary to visit the École des Beaux-Arts de l'Indochine in Hanoi, 1920–1939, and bursary for residence at the Casa de Velázquez in Madrid, 1929–present.

Winners in the Architecture category.

The Prix de Rome for Architecture was created in 1720.

Prix de Rome (Netherlands).

A Prix de Rome was also established in the Kingdom of Holland by Lodewijk Napoleon to award young artists and architects. During the years 1807–1810 prize winners were sent to Paris and onwards to Rome for study. In 1817, after the Netherlands had gained its independence, King Willem I restarted the prize; though it took until 1823 before the new "Royal Academies" of Amsterdam and Antwerp could organize the juries. Suspended in 1851 it was reinstated in 1870 by William III of the Netherlands. Since then the winners have been selected by the Rijksakademie in Amsterdam under the main headings of architecture and the visual arts.

Prix de Rome (Belgium).

The Belgian Prix de Rome (Dutch: Prijs van Rome) is an award for young artists, created in 1832, following the example of the original French Prix de Rome. The Royal Academy of Fine Arts Antwerp organised the prize until 1920, when the national government took over. The first prize is also sometimes called the Grand Prix de Rome. There were distinct categories for architecture, painting, sculpture and music.

The Prix de Rome () or Grand Prix de Rome was a French scholarship for arts students, initially for painters and sculptors, that was established in 1663 during the reign of Louis XIV of France. Winners were awarded a bursary that allowed them to stay in Rome for three to five years at the expense of the state. The prize was extended to architecture in 1720, music in 1803, and engraving in 1804. The prestigious award was abolished in 1968 by André Malraux, the Minister of Culture.

Římská cena (Prix de Rome) bylo stipendium pro studenty umění. Byla založena roku 1663 ve Francii za vlády Ludvíka XIV.. Byla to každoroční příležitost pro nadějné umělce (malíře, sochaře a architekty), kteří podrobili svůj talent obtížné zkoušce. Udílení ceny bylo organizováno Královskou akademií malířství a sochařství a bylo otevřeno jejím studentům. Vítěz vyhrál pobyt v Římě v paláci Mancini na náklady francouzského krále.


Techniques.

There are a number of techniques used in negative campaigning. Among the most effective is running advertisements attacking an opponent's personality, record, or opinion. There are two main types of ads used in negative campaigning: attack and contrast.  Attack ads focus exclusively on the negative aspects of the opponent. There is no positive content in an attack ad, whether it is about the candidate or the opponent. Attack ads usually identify the risks associated with the opponent, often exploiting people's fears to manipulate and lower the impression voters have of the opponent. Because attack ads have no positive content, they have the potential to be more influential than contrast ads in shaping voters’ views of the sponsoring candidate's opponent.  Unlike attack ads, contrast ads contain information about both the candidate and the opponent. The information about the candidate is positive, while the information about the opponent is negative. Contrast ads compare and contrast the candidate with the opponent, juxtaposing the positive information about the candidate with the negative information of the opponent. Because contrast ads must contain positive information, contrast ads are seen as less damaging to the political process than attack ads.  One of the most famous such ads was "Daisy Girl" by the campaign of Lyndon B. Johnson that successfully portrayed Republican Barry Goldwater as threatening nuclear war. Common negative campaign techniques include painting an opponent as soft on criminals, dishonest, corrupt, or a danger to the nation. One common negative campaigning tactic is attacking the other side for running a negative campaign.  Dirty tricks are also common in negative political campaigns. These generally involve secretly leaking damaging information to the media. This isolates a candidate from backlash and also does not cost any money. The material must be substantive enough to attract media interest, however, and if the truth is discovered it could severely damage a campaign. Other dirty tricks include trying to feed an opponent's team false information hoping they will use it and embarrass themselves.  Often a campaign will use outside organizations, such as lobby groups, to launch attacks. These can be claimed to be coming from a neutral source and if the allegations turn out not to be true the attacking candidate will not be damaged if the links cannot be proven. Negative campaigning can be conducted by proxy. For instance, highly partisan ads were placed in the 2004 U.S. presidential election by allegedly independent bodies like MoveOn.org and Swift Boat Veterans for Truth.  Push polls are attacks disguised as telephone polls. They might ask a question like "How would you react if Candidate A was revealed to beat his wife?", giving the impression that Candidate A might beat his wife. Members of the media and of the opposing party are deliberately not called making these tactics all but invisible and unprovable.  G. Gordon Liddy played a major role in developing these tactics during the Nixon campaign playing an important advisory of rules that led to the campaign of 1972. James Carville, campaign manager of Bill Clinton's 1992 election, is also a major proponent of negative tactics. Lee Atwater, best known for being an advisor to presidents Ronald Reagan and George H.W. Bush, also pioneered many negative campaign techniques seen in political campaigns today.

Advantages.

Sponsors of overt negative campaigns often cite reasons to support mass communication of negative ideas. The Office of National Drug Control Policy uses negative campaigns to steer the public away from health risks. Similar negative campaigns have been used to rebut mass marketing by tobacco companies, or to discourage drunk driving. Those who conduct negative political campaigns sometimes say the public needs to know about the person he or she is voting for, even if it is bad. In other words, if a candidate's opponent is a crook or a bad person, then he or she should be able to tell the public about it.  Martin Wattenberg and Craig Brians, of the University of California, Irvine, considered in their study whether negative campaigning mobilizes or alienates voters. They concluded that data used by Stephen Ansolabehere in a 1994 American Political Science Review article to advance the hypothesis that negative campaigning demobilizes voters was flawed.  A subsequent study done by Ansolabehere and Shanto Iyengar in 1995 corrected some of the previous study's flaws. This study concluded that negative advertising suppressed voter turnout, particularly for Independent voters. They speculated that campaigns tend to go negative only if the Independent vote is leaning toward the opponent. In doing so, they insure that the swing voters stay home, leaving the election up to base voters. They also found that negative ads have a greater impact on Democrats than on Republicans. According to them, base Republicans will vote no matter what (and will vote only for a Republican), but Democrats can be influenced to either stay home and not vote at all or to switch sides and vote for a Republican. This, combined with the effect negativity has on Independents, led them to conclude that Republicans benefit more from going negative than Democrats.  Other researchers have found different, more positive outcomes from negative campaigns. Rick Farmer, PhD, an assistant professor of political science at the University of Akron found that negative ads are more memorable than positive ads when they reinforce a preexisting belief and are relevant to the central issues of a marketing campaign. Researchers at the University of Georgia found the impact of negative ads increases over time, while positive ads used to counteract negative ads lack the power of negative ads. Research also suggests negative campaigning introduces controversy and raises public awareness through additional news coverage.  Kyle Mattes and David P. Redlawsk in "The Positive Case for Negative Campaigning" show through surveys and experiments that negative campaigning may provide informational benefits for voters. Without negativity, voters would not have full information about all of their choices, since no candidate will say anything bad about herself. They argue that candidates have to point out the flaws in their opponents for voters to be fully informed.  Most recent research distinguishes between a dichotomous (positive versus negative) and graded conceptualization of negative campaigning. The latter accounts for differences in the strength of negative communication. It argues that positive (i.e. information about parties and candidates) and derogatory (i.e. democratic dissaffection) effects of negative campaigning will depend on the strength or intensity of negative campaigning. Similarly, political candidates and parties have been found to adapt the strength of their negative messages during election campaigns in order to preserve the chances for post-elecoctral collaboration in countries with frequent coalition governments.

Risks and consequences.

Some strategists say that an effect of negative campaigning is that while it motivates the base of support it can alienate centrist and undecided voters from the political process, reducing voter turnout and radicalizing politics. In a study done by Gina Garramone about how negative advertising affects the political process, it was found that a consequence of negative campaigning is greater image discrimination of the candidates and greater attitude polarization. While positive ads also contributed to the image discrimination and attitude polarization, Garramone found that negative campaigning played a more influential role in the discrimination and polarization than positive campaigning.  Negative ads can produce a backlash. A disastrous ad was run by the Progressive Conservative Party of Canada in the 1993 Canadian federal election, apparently emphasizing Liberal Party of Canada leader Jean Chrétien's Bell's Palsy partial facial paralysis in a number of unflattering photos, with the subtext of criticizing his platforms. Chrétien took maximum advantage of the opportunity to gain the public's sympathy as a man who struggled with a physical disability and his party's subsequent overwhelming victory in the election helped reduce the governing Progressive Conservatives to two seats, and losing official party status.  A similar backlash happened to the Liberal Party in the 2006 federal election for running an attack ad that suggested that Conservative leader Stephen Harper would use Canadian soldiers to patrol Canadian cities, and impose some kind of martial law. The ad was only available from the Liberal Party's web site for a few hours prior to the release of the attack ads on television; nevertheless, it was picked up by the media and widely criticized for its absurdity, in particular the sentence "we're not making this up; we're not allowed to make this stuff up". Liberal MP Keith Martin expressed his disapproval of "whoever the idiot who approved that ad was," shortly before Liberal leader Paul Martin (no relation) stated that he had personally approved them. The effect of the ads was to diminish the credibility of the party's other attack ads. It offended many Canadians, particularly those in the military, some of whom were fighting in Afghanistan at the time. (See 2006 Canadian federal election)  More recently, in the 2008 US Senate race in North Carolina, Republican incumbent Elizabeth Dole attempted an attack ad on Democratic challenger Kay Hagan, who had taken a small lead in polls, by tying her to atheists. Dole's campaign released an ad questioning Hagan's religion and it included a voice saying "There is no God!" over a picture of Kay Hagan's face. The voice was not Hagan's but it is believed the ad implied that it was. Initially, it was thought the ad would work as religion has historically been a very important issue to voters in the American south, but the ad produced a backlash across the state and Hagan responded forcefully with an ad saying that she was a Sunday school teacher and was a religious person. Hagan also claimed Dole was trying to change the subject from the economy (the ad appeared around the same time as the 2008 financial crisis). Hagan's lead in polls doubled and she won the race by a nine-point margin.  Because of the possible harm that can come from being seen as a negative campaigner, candidates often pledge to refrain from negative attacks. This pledge is usually abandoned when an opponent is perceived to be "going negative," with the first retaliatory attack being, ironically, an accusation that the opponent is a negative campaigner.  While some research has found advantages and other has found disadvantages, some studies find no difference between negative and positive approaches.  Research published in the Journal of Advertising found that negative political advertising makes the body want to turn away physically, but the mind remembers negative messages. The findings are based on research conducted by James Angelini, professor of communication at the University of Delaware, in collaboration with Samuel Bradley, assistant professor of advertising at Texas Tech University, and Sungkyoung Lee of Indiana University, which used ads that aired during the 2000 presidential election. During the study, the researchers placed electrodes under the eyes of willing participants and showed them a series of 30-second ads from both the George W. Bush and Al Gore campaigns. The electrodes picked up on the "startle response," the automatic eye movement typically seen in response to snakes, spiders and other threats. Compared to positive or neutral messages, negative advertising prompted greater reflex reactions and a desire to move away.

Notable examples.

United States.

In United States politics, negative campaigning has been called "as American as Mississippi mud" and "as American as apple pie". Some research suggests negative campaigning is the norm in all political venues, mitigated only by the dynamics of a particular contest.

Negative campaigning or mudslinging is the process of deliberate spreading negative information about someone or something to worsen the public image of the described.

Negativní kampaň (), neboli útočný volební boj, je spojen především s politickým děním ve Spojených státech amerických. Primárním cíle této kampaně je zničit nebo alespoň oslabit protivníka, v tomto případě politického protikandidáta. Použití negativní kampaně je neetické a v některých zemích dokonce zakázané.


Life.

He was born in Paphlagonia and taught at Phasis. Apart from a short sojourn in Rome, he resided in Constantinople during the rest of his life. He was the son of Eugenius, who was also a distinguished philosopher, and who is more than once mentioned in the orations of Themistius. Themistius was instructed by his father in philosophy, and devoted himself chiefly to Aristotle, though he also studied Pythagoreanism and Platonism. While still a youth he wrote commentaries on Aristotle, which were made public without his consent, and obtained for him a high reputation. He passed his youth in Asia Minor and Syria. He first met with Constantius II when the emperor visited Ancyra in Galatia in the eleventh year of his reign, 347, on which occasion Themistius delivered the first of his extant orations, "Peri Philanthropias". It was not long after that he moved to Constantinople, where he taught philosophy for twenty years. In 355 he was made a senator; and the letter is still extant, in which Constantius recommends him to the senate, and speaks in the highest terms both of Themistius himself and of his father. We also possess the oration of thanks which Themistius addressed to the senate of Constantinople early in 356, in reply to the emperor's letter. In 357 he recited in the senate of Constantinople two orations in honour of Constantius, which were intended to have been delivered before the emperor himself, who was then at Rome. As a reward, Constantius conferred upon him the honour of a bronze statue; and, in 361, he was appointed to the praetorian rank by a decree still extant. In 358–359, Themistius may have served as proconsul of Constantinople in 358; he was the last to hold that office, before the position was elevated to the status of urban prefect.  Constantius died in 361; but Themistius, as a philosopher and non-Christian, naturally retained the favour of Julian, who spoke of him as the worthy senator of the whole world, and as the first philosopher of his age. The Suda states that Julian made Themistius prefect of Constantinople; but this is disproved by the speech delivered by Themistius, when he was really appointed to that office under Theodosius. Shortly before the death of Julian in 363, Themistius delivered an oration in honour of him, which is no longer extant, but which is referred to at some length by Libanius, in a letter to Themistius. In 364 he went, as one of the deputies from the senate, to meet Jovian at Dadastana, on the border of Galatia and Bithynia, and to confer the consulate upon him; and on this occasion he delivered an oration, which he afterwards repeated at Constantinople, in which he claims full liberty of conscience to practice any religion. In the same year he delivered an oration at Constantinople, in honour of the accession of Valentinian I and Valens, in the presence of the latter. His next oration is addressed to Valens, congratulating him on his victory over Procopius in June 366, and interceding for some of the rebels; it was delivered in 367. In the next year he accompanied Valens to the Danube in the second campaign of the Gothic war, and delivered before the emperor, at Marcianopolis, a congratulatory oration upon his "Quinquennalia", 368. His next orations are to the young Valentinian II upon his consulship, 369, and to the senate of Constantinople, in the presence of Valens, in honour of the peace granted to the Goths, 370. On March 28, 373, he addressed to Valens, who was then in Syria, a congratulatory address upon the emperor's entrance on the tenth year of his reign. It was also while Valens was in Syria, that Themistius addressed to him an oration by which he persuaded him to cease from his persecution of the Catholic party. In addition to these orations, which prove that the orator was in high favour with the emperor, we have the testimony of Themistius himself to his influence with Valens.  In 377 we find him at Rome, where he appears to have gone on an embassy to Gratian, to whom he there delivered his oration entitled "Erotikos". On the association of Theodosius I in the empire by Gratian, at Sirmium, in 379, Themistius delivered an elegant oration, congratulating the new emperor on his elevation. Of his remaining orations some are public and some private; but few of them demand special notice as connected with the events of his life. In 384, (about the first of September), he was made prefect of Constantinople, an office which had been offered to him, but declined, several times before. He only held the prefecture a few months, as we learn from an oration delivered after he had laid down the office, in which he mentions, as he had done even six years earlier, and more than once in the interval, his old age and ill-health. From the thirty-fourth oration we also learn that he had previously held the offices of "princeps senatus" and "praefectus annonae", besides his embassy to Rome; in another oration he mentions ten embassies on which he had been sent before his prefecture; and in another, composed probably about 387, he says that he has been engaged for nearly forty years in public business and in embassies. So great was the confidence placed in him by Theodosius, that, though Themistius was not a Christian, the emperor, when departing for the West to oppose Magnus Maximus, entrusted his son Arcadius to the tutorship of the philosopher, 387-388. Nothing is known about Themistius after this time; and he may have died around 390. Besides the emperors, he numbered among his friends the chief orators and philosophers of the age, Christian and non-Christian. Not only Libanius, but Gregory of Nazianzus also was his friend and correspondent, and the latter, in an epistle still extant, calls him the "king of arguments."

Work.

The orations of Themistius, extant in the time of Photius (9th century), were thirty-six in number. Of these, thirty-three have come down to us in Greek. Two of them, however, (Orations 23 and 33, and perhaps Oration 28) are not fully preserved, and one (Oration 25) is a brief statement, not a full oration. Modern editions of the Orations have thirty-four pieces, because a Latin address to Valens has been included as Oration 12. It is now believed though that this Latin address is a 16th-century creation. The final oration (Oration 34) was discovered as recently as 1816 by Angelo Mai in the Ambrosian Library at Milan. There are, in addition, a few other fragments which may come from lost Orations, as well as an additional work which survives in Syriac and another preserved in Arabic.  The philosophical works of Themistius must have been very voluminous; for Photius tells us that he wrote commentaries on all the books of Aristotle, besides useful abstracts of the "Posterior Analytics", the books "On the Soul", and the "Physics", and that there were works of his on Plato; "and, in a word, he is a lover and eager student of philosophy." The Suda mentions his epitome of the "Physics" of Aristotle, in eight books; of the "Prior Analytics", in two books; of the "Posterior Analytics", in two books; of the treatise "On the Soul", in seven books; and of the "Categories" in one book.  The epitomes which survive are:  In addition to these works, two surviving anonymous paraphrases were mistakenly attributed to him in the Byzantine era, and are now assigned to a Pseudo-Themistius:  His paraphrases of Aristotle's "Posterior Analytics", "Physics" and "On the Soul" are valuable; but the orations in which he panegyrizes successive emperors, comparing them to Plato's true philosopher, and even to the idea itself, are intended to flatter. Boëthius describes him as, "disertissimus" (or "diligentissimus") "scriptor ac lucidus, et omnia ad facilitatem intelligentiae revocans".  In philosophy Themistius was an eclectic. He held that Plato and Aristotle were in substantial agreement, that God has made men free to adopt the mode of worship they prefer, and that Christianity and Hellenism were merely two forms of the one universal religion.

Themistius (, "Themistios"; 317, Paphlagonia – c. 390 AD, Constantinople), nicknamed Euphrades, (eloquent), was a statesman, rhetorician, and philosopher. He flourished in the reigns of Constantius II, Julian, Jovian, Valens, Gratian, and Theodosius I; and he enjoyed the favour of all those emperors, notwithstanding their many differences, and the fact that he himself was not a Christian. He was admitted to the senate by Constantius in 355, and he was prefect of Constantinople in 384 on the nomination of Theodosius. Of his many works, thirty-three orations of his have come down to us, as well as various commentaries and epitomes of the works of Aristotle.

Themistios, řecky Θεμίστιος (asi 317 – 388), byl pohanský filosof a rétor. Pocházel z Paflagonie, působil u konstantinopolského císařského dvora. Usiloval o soulad mezi pohanskou aristokracií a křesťanským panovníkem.


Etymology.

"Wildebeest" is Dutch for "wild beast" or "wild cattle" in Afrikaans ("bees" "cattle"), while "Connochaetes" derives from the Greek words κόννος, "kónnos", "beard", and χαίτη, "khaítē", "flowing hair", "mane". Some sources claim the name "gnu" originates from the Khoikhoi name for these animals, "t'gnu". Others contend the name and its pronunciation in English go back to the word "!nu:" used for the black wildebeest by the San people.

Classification.

Taxonomy and evolution.

The wildebeest, genus "Connochaetes", is placed under the family Bovidae and subfamily Alcelaphinae, where its closest relatives are the hartebeest ("Alcelaphus" spp.), the hirola ("Beatragus hunteri"), and species in the genus "Damaliscus", such as the topi, the tsessebe, the blesbok and the bontebok. The name "Connochaetes" was given by German zoologist Hinrich Lichtenstein in 1812.  Dutch settlers first discovered wildebeest in about 1700, on their way to the interior of South Africa. Due to their resemblance to wild cattle, these people called them "wild ox" or "wildebeest". The blue wildebeest was first known to westerners in the northern part of South Africa a century later, in the 1800s.  In the early 20th century, one species of the wildebeest, "C. albojubatus", was identified in eastern Africa. In 1914, two separate races of the wildebeest were introduced, namely "Gorgon a. albojubatus" ("Athi white-bearded wildebeest") and "G. a. mearnsi" ("Loita white-bearded wildebeest"). However, in 1939, the two were once again merged into a single race, "Connochaetes taurinus albojubatus". In the mid-20th century, two separate forms were recognised, "Gorgon taurinus hecki" and "G. t. albojubatus". Finally, two distinct types of wildebeest – the blue and black wildebeest – were identified. The blue wildebeest was at first placed under a separate genus, "Gorgon", while the black wildebeest belonged to the genus "Connochaetes". Today, they are united in the single genus "Connochaetes", with the black wildebeest being named ("C. gnou") and the blue wildebeest ("C. taurinus").  According to a mitochondrial DNA analysis, the black wildebeest are estimated to have diverged from the main lineage during the Middle Pleistocene and became a distinct species around a million years ago. A divergence rate around 2% has been calculated. The split does not seem to have been driven by competition for resources, but instead because each species adopted a different ecological niche and occupied a different trophic level.  Blue wildebeest fossils dating back some 2.5 million years ago are common and widespread. They have been found in the fossil-bearing caves at the Cradle of Humankind north of Johannesburg. Elsewhere in South Africa, they are plentiful at such sites as Elandsfontein, Cornelia, and Florisbad. The earliest fossils of the black wildebeest were found in sedimentary rock in Cornelia in the Orange Free State and dated back about 800,000 years. Today, five subspecies of the blue wildebeest are recognised, while the black wildebeest has no named subspecies.

Genetics and hybrids.

The diploid number of chromosomes in the wildebeest is 58. Chromosomes were studied in a male and a female wildebeest. In the female, all except a pair of very large submetacentric chromosomes were found to be acrocentric. Metaphases were studied in the male's chromosomes, and very large submetacentric chromosomes were found there, as well, similar to those in the female both in size and morphology. Other chromosomes were acrocentric. The X chromosome is a large acrocentric and the Y chromosome a minute one.  The two species of the wildebeest are known to hybridise. Male black wildebeest have been reported to mate with female blue wildebeest and vice versa. The differences in social behaviour and habitats have historically prevented interspecific hybridisation between the species, but hybridisation may occur when they are both confined within the same area. The resulting offspring are usually fertile. A study of these hybrid animals at Spioenkop Dam Nature Reserve in South Africa revealed that many had disadvantageous abnormalities relating to their teeth, horns, and the wormian bones in the skull. Another study reported an increase in the size of the hybrid as compared to either of its parents. In some animals, the tympanic part of the temporal bone is highly deformed, and in others, the radius and ulna are fused.

Characteristics of the species.

Both species of wildebeest are even-toed, horned, greyish-brown ungulates resembling cattle. Males are larger than females and both have heavy forequarters compared to their hindquarters. They have broad muzzles, Roman noses, and shaggy manes and tails. The most striking morphological differences between the black and blue wildebeest are the orientation and curvature of their horns and the colour of their coats. The blue wildebeest is the bigger of the two species. In males, blue wildebeest stand 150 cm tall at the shoulder and weigh around 250 kg, while the black wildebeest stands 111 to 120 cm tall and weighs about 180 kg. In females, blue wildebeest have a shoulder height of 135 cm and weigh 180 kg while black wildebeest females stand 108 cm at the shoulder and weigh 155 kg. The horns of blue wildebeest protrude to the side, then curve downwards before curving up back towards the skull, while the horns of the black wildebeest curve forward then downward before curving upwards at the tips. Blue wildebeest tend to be a dark grey colour with stripes, but may have a bluish sheen. The black wildebeest has brown-coloured hair, with a mane that ranges in colour from cream to black, and a cream-coloured tail. The blue wildebeest lives in a wide variety of habitats, including woodlands and grasslands, while the black wildebeest tends to reside exclusively in open grassland areas. In some areas, the blue wildebeest migrates over long distances in the winter, whereas the black wildebeest does not. The milk of the female black wildebeest contains a higher protein, lower fat, and lower lactose content than the milk of the blue wildebeest. Wildebeest can live more than 40 years, though their average lifespan is around 20 years.

Distribution and habitat.

Wildebeest inhabit the plains and open woodlands of parts of Africa south of the Sahara. The black wildebeest is native to the southernmost parts of the continent. Its historical range included South Africa, Eswatini, and Lesotho, but in the latter two countries, it was hunted to extinction in the 19th century. It has now been reintroduced to them and also introduced to Namibia, where it has become well established. It inhabits open plains, grasslands, and Karoo shrublands in both steep mountainous regions and lower undulating hills at altitudes varying between. In the past, it inhabited the highveld temperate grasslands during the dry winter season and the arid Karoo region during the rains. However, as a result of widespread hunting, the black wildebeest no longer occupies its historical range or makes migrations, and is now largely limited to game farms and protected reserves.  The blue wildebeest is native to eastern and southern Africa. Its range includes Kenya, Tanzania, Botswana, Zambia, Zimbabwe, Mozambique, South Africa, Swaziland and Angola. It is no longer found in Malawi but has been successfully reintroduced into Namibia. Blue wildebeest are mainly found in short grass plains bordering bush-covered acacia savannas, thriving in areas that are neither too wet nor too dry. They can be found in habitats that vary from overgrazed areas with dense bush to open woodland floodplains. In East Africa, the blue wildebeest is the most abundant big game species, both in population and biomass. It is a notable feature of the Serengeti National Park in Tanzania, the Maasai Mara National Reserve in Kenya and the Liuwa Plain National Park in Zambia.

Migration.

Not all wildebeest are migratory. Black wildebeest herds are often nomadic or may have a regular home range of. Bulls may occupy territories, usually about apart, but this spacing varies according to the quality of the habitat. In favourable conditions, they may be as close as, or they may be as far apart as in poor habitat. Female herds have home ranges of about in size. Herds of nonterritorial bachelor males roam at will and do not seem to have any restrictions on where they wander.  Blue wildebeest have both migratory and sedentary populations. In the Ngorongoro, most animals are sedentary and males maintain a network of territories throughout the year, though breeding is seasonal in nature. Females and young form groups of about 10 individuals or join together in larger aggregations, and nonterritorial males form bachelor groups. In the Serengeti and Tarangire ecosystems, populations are mostly migratory, with herds consisting of both sexes frequently moving, but resident subpopulations also exist. During the rutting season, the males may form temporary territories for a few hours or a day or so, and attempt to gather together a few females with which to mate, but soon they have to move on, often moving ahead to set up another temporary territory.  In the Maasai Mara game reserve, a non-migratory population of blue wildebeest had dwindled from about 119,000 animals in 1977 to about 22,000 in 1997. The reason for the decline is thought to be the increasing competition between cattle and wildebeest for a diminishing area of grazing land as a result of changes in agricultural practices, and possibly fluctuations in rainfall.  Each year, some East African populations of blue wildebeest have a long-distance migration, seemingly timed to coincide with the annual pattern of rainfall and grass growth. The timing of their migrations in both the rainy and dry seasons can vary considerably (by months) from year to year. At the end of the wet season (May or June in East Africa), wildebeest migrate to dry-season areas in response to a lack of surface (drinking) water. When the rainy season begins again (months later), animals quickly move back to their wet-season ranges. Factors suspected to affect migration include food abundance, surface water availability, predators, and phosphorus content in grasses. Phosphorus is a crucial element for all life forms, particularly for lactating female bovids. As a result, during the rainy season, wildebeest select grazing areas that contain particularly high phosphorus levels. One study found, in addition to phosphorus, wildebeest select ranges containing grass with relatively high nitrogen content.  Aerial photography has revealed that a level of organisation occurs in the movement of the herd that cannot be apparent to each individual animal; for example, the migratory herd exhibits a wavy front, and this suggests that some degree of local decision-making is taking place. Numerous documentaries feature wildebeest crossing rivers, with many being eaten by crocodiles or drowning in the attempt. While having the appearance of a frenzy, recent research has shown a herd of wildebeest possesses what is known as a "swarm intelligence", whereby the animals systematically explore and overcome the obstacle as one.

Ecology.

Predators.

Major predators that feed on wildebeest include the lion, hyena, African wild dog, cheetah, leopard, and crocodile, which seem to favour the wildebeest over other prey. Wildebeest, however, are very strong, and can inflict considerable injury even to a lion. Wildebeest have a maximum running speed of around. The primary defensive tactic is herding, where the young animals are protected by the older, larger ones, while the herd runs as a group. Typically, the predators attempt to isolate a young or ill animal and attack without having to worry about the herd. Wildebeest have developed additional sophisticated cooperative behaviours, such as animals taking turns sleeping while others stand guard against a night attack by invading predators. Wildebeest migrations are closely followed by vultures, as wildebeest carcasses are an important source of food for these scavengers. The vultures consume about 70% of the wildebeest carcasses available. Decreases in the number of migrating wildebeest have also had a negative effect on the vultures. In the Serengeti ecosystem, Tanzania, wildebeest may help facilitate the migration of other, smaller-bodied grazers, such as Thomson's gazelles ("Eudorcas thomsonii"), which eat the new-growth grasses stimulated by wildebeest foraging.

Interactions with nonpredators.

Zebras and wildebeest group together in open savannah environments with high chances of predation. This grouping strategy reduces predation risk because larger groups decrease each individual's chance of being hunted, and predators are more easily seen in open areas. The seasonal presence of thousands of migratory wildebeests reduces local lion predation on giraffe calves, resulting in greater survival of giraffes.  Wildebeest can also listen in on the alarm calls of other species, and by doing so, can reduce their risk of predation. One study showed, along with other ungulates, wildebeests responded more strongly to the baboon alarm calls compared to the baboon contest calls, though both types of calls had similar patterns, amplitudes, and durations. The alarm calls were a response of the baboons to lions, and the contest calls were recorded when a dispute between two males occurred.

Breeding and reproduction.

Wildebeest do not form permanent pair bonds and during the mating season, or rut, the males establish temporary territories and try to attract females into them. These small territories are about, with up to 300 territories per. The males defend these territories from other males while competing for females that are coming into oestrus. The males use grunts and distinctive behaviour to entice females into their territories. Wildebeest usually breed at the end of the rainy season when the animals are well fed and at their peak of fitness. This usually occurs between May and July, and birthing usually takes place between January and March, at the start of the wet season. Wildebeest females breed seasonally and ovulate spontaneously.  The estrous cycle is about 23 days and the gestation period lasts 250 to 260 days. The calves weigh about at birth and scramble to their feet within minutes, being able to move with the herd soon afterwards, a fact on which their survival relies. The main predator of the calves is the spotted hyena. The calving peak period lasts for 2–3 weeks, and in small subpopulations and isolated groups, mortality of calves may be as high as 50%. However, in larger aggregations, or small groups living near large herds, survival rates may be over 80%.  Groups of wildebeest females and young live in the small areas established by the male. When groups of wildebeest join together, the female to male ratio is higher because the females choose to move to the areas held by a smaller number of males. This female-dominated sex ratio may be due to illegal hunting and human disturbance, with higher male mortality having been attributed to hunting.

Threats and conservation.

Today, many wildebeest populations are experiencing rapid declines. Overland migration as a biological process requires large, connected landscapes, which are increasingly difficult to maintain, particularly over the long term, when human demands on the landscape compete. The most acute threat comes from migration barriers, such as fences and roads. In one of the more striking examples of the consequences of fence-building on terrestrial migrations, Botswanan authorities placed thousands of kilometres of fences across the Kalahari that prevented wildebeests from reaching watering holes and grazing grounds, resulting in the deaths of tens of thousands of individuals, reducing the wildebeest population to less than 10% of its previous size. Illegal hunting is a major conservation concern in many areas, along with natural threats posed by main predators (which include lions, leopards, African hunting dogs, cheetahs and hyenas). Where the black and blue wildebeest share a common range, the two can hybridise, and this is regarded as a potential threat to the black wildebeest.  The black wildebeest has been classified as a least-concern species by the International Union for Conservation of Nature in the "IUCN Red List". The populations of this species are on an increase. Now, more than 18,000 individuals are believed to remain, 7,000 of which are in Namibia, outside their natural range, and where it is farmed. Around 80% of the wildebeest occurs in private areas, while the other 20% is confined in protected areas. Its introduction into Namibia has been a success and numbers have increased substantially there from 150 in 1982 to 7,000 in 1992. The blue wildebeest has also been rated as of least concern. The population trend is stable, and their numbers are estimated to be around 1,500,000 – mainly due to the increase of the populations in Serengeti National Park (Tanzania) to 1,300,000. However, the numbers of one of the subspecies, the eastern white-bearded wildebeest ("C. t. albojubatus") have seen a steep decline. Population density ranges from 0.15/km. in Hwange and Etosha National Parks to 35/km in Ngorongoro Conservation Area and Serengeti National Park.

Uses and interaction with humans.

Wildebeest provide several useful animal products. The hide makes good-quality leather and the flesh is coarse, dry and rather hard. Wildebeest are killed for food, especially to make biltong in Southern Africa. This dried game meat is a delicacy and an important food item in Africa. The meat of females is more tender than that of males, and is the most tender during the autumn season. Wildebeest are a regular target for illegal meat hunters because their numbers make them easy to find. Cooks preparing the wildebeest carcass usually cut it into 11 pieces. The estimated price for wildebeest meat was about US$0.47 per around 2008. The silky, flowing tail of the black wildebeest is used to make fly-whisks or "chowries".  Wildebeest benefit the ecosystem by increasing soil fertility with their excreta. They are economically important for human beings, as they are a major tourist attraction. They also provide important products, such as leather, to humans. Wildebeest, however, can also have a negative impact on humans. Wild individuals can be competitors of commercial livestock, and can transmit diseases and cause epidemics among animals, particularly domestic cattle. They can also spread ticks, lungworms, tapeworms, flies, and paramphistome flukes.

Cultural depictions.

The black wildebeest is depicted on the coat of arms of the Province of Natal in South Africa. Over the years, the South African authorities have issued several stamps displaying the animal and the South African Mint has struck a two cent piece with a prancing black wildebeest.  Movies and television shows also feature wildebeests, including "Khumba" (Mama V), "The Wild" (Kazar and his minions), "All Hail King Julien" (Vigman Wildebeest), "Phineas and Ferb" (Newton the Gnu), "The Great Space Coaster" (newscaster Gary Gnu), and "The Lion King" (the wildebeest stampede that resulted in Mufasa's death).  Michael Flanders wrote a humorous song called "The Gnu", which was very popular when he performed it, with Donald Swann, in a revue called "At the Drop of a Hat", which opened in London on 31 December 1956.  In the 1970s British tea brand Typhoo ran a series of Television advertisements featuring an animated anthropomorphic Gnu character.  The wildebeest is the mascot of the GNU Project and GNU operating system.  In the "Llama Llama" picture-book series by Anna Dewdney, an anthropomorphised wildebeest named Nelly Gnu is the main character, Llama Llama's best friend, and is also featured in a title of her own, "Nelly Gnu and Daddy Too".

The wildebeest (,, plural wildebeest or wildebeests), also called the gnu ( or ), is an antelope in the genus Connochaetes. It belongs to the family Bovidae, which includes antelopes, cattle, goats, sheep, and other even-toed horned ungulates. "Connochaetes" includes two species, both native to Africa: the black wildebeest or white-tailed gnu ("C. gnou"), and the blue wildebeest or brindled gnu ("C. taurinus").

Pakůň ("Connochaetes") je rod velkých přežvýkavých savců z čeledi turovitých ("Bovidae") patřící mezi buvolce. Žijí v subsaharské Africe v savanách.


Geography.

Lower Manhattan is defined most commonly as the area delineated on the north by 14th Street, on the west by the Hudson River, on the east by the East River, and on the south by New York Harbor (also known as Upper New York Bay). When referring specifically to the Lower Manhattan business district and its immediate environs, the northern border is commonly designated by thoroughfares about a mile-and-a-half south of 14th Street and a mile north of the island's southern tip: approximately around Chambers Street from near the Hudson east to the Brooklyn Bridge entrances and overpass. Two other major arteries are also sometimes identified as the northern border of "Lower" or "Downtown Manhattan": Canal Street, roughly half a mile north of Chambers Street, and 23rd Street, roughly half a mile north of 14th Street.  The Lower Manhattan business district forms the core of the area below Chambers Street. It includes the Financial District (often referred to as Wall Street, after its primary artery) and the World Trade Center site. At the island's southern tip is Battery Park; City Hall is just to the north of the Financial District. Also south of Chambers Street are the planned community of Battery Park City and the South Street Seaport historic area. The neighborhood of TriBeCa straddles Chambers Street on the west side; at the street's east end is the giant Manhattan Municipal Building. North of Chambers Street and the Brooklyn Bridge and south of Canal Street lies most of New York's oldest Chinatown neighborhood. Many court buildings and other government offices are also located in this area. The Lower East Side neighborhood straddles Canal Street. North of Canal Street and south of 14th Street are the neighborhoods of SoHo, the Meatpacking District, the West Village, Greenwich Village, Little Italy, Nolita, and the East Village. Between 14th and 23rd streets are lower Chelsea, Union Square, the Flatiron District, as well as Gramercy, with the large residential development known as Peter Cooper Village—Stuyvesant Town situated on the eastern flank of this zone.

History.

Lenape and New Netherland.

The area that would eventually encompass modern-day New York City was inhabited by the Lenape people. These groups of culturally and linguistically identical Native Americans traditionally spoke an Algonquian language now referred to as "Unami".  European settlement began with the founding of a Dutch fur trading post in Lower Manhattan, later called New Amsterdam () in 1626. The first fort was built at The Battery to protect New Netherland.  Soon thereafter, most likely in 1626, construction of Fort Amsterdam began. Later, the Dutch West Indies Company imported African slaves to serve as laborers; they helped to build the wall that defended the town against English and native attacks. Early directors included Willem Verhulst and Peter Minuit. Willem Kieft became a director in 1638 but five years later was embroiled in Kieft's War against the Native Americans. The Pavonia Massacre, across the Hudson River in present-day Jersey City resulted in the death of 80 natives in February 1643. Following the massacre, Algonquian tribes joined forces and nearly defeated the Dutch. The Dutch Republic sent additional forces to the aid of Kieft, leading to the overwhelming defeat of the Native Americans and a peace treaty on August 29, 1645.  On May 27, 1647, Peter Stuyvesant was inaugurated as director general upon his arrival. The colony was granted self-government in 1652, and New Amsterdam was formally incorporated as a city on February 2, 1653. The first mayors ("burgemeesters") of New Amsterdam, Arent van Hattem and Martin Cregier, were appointed in that year.

17th and 18th centuries.

In 1664, the English conquered the area and renamed it "New York" after the Duke of York and the city of York in Yorkshire.  At that time, people of African descent made up 20% of the population of the city, with European settlers numbering approximately 1,500, and people of African descent numbering 375 (with 300 of that 375 enslaved and 75 free). While it has been claimed that African slaves comprised 40% of the small population of the city at that time, this claim has not been substantiated. During the mid 1600s, farms of free blacks covered where Washington Square Park later developed.  The Dutch briefly regained the city in 1673, renaming the city "New Orange", before permanently ceding the colony of New Netherland to the English for what is now Suriname in November 1674.  The new English rulers of the formerly Dutch New Amsterdam and New Netherland renamed the settlement back to New York. As the colony grew and prospered, sentiment also grew for greater autonomy. In the context of the Glorious Revolution in England, Jacob Leisler led Leisler's Rebellion and effectively controlled the city and surrounding areas from 1689–1691, before being arrested and executed.  By 1700, the Lenape population of New York had diminished to 200. By 1703, 42% of households in New York had slaves, a higher percentage than in Philadelphia or Boston.  The 1735 libel trial of John Peter Zenger in the city was a seminal influence on freedom of the press in North America. It would be a standard for the basic articles of freedom in the United States Declaration of Independence. By the 1740s, with expansion of settlers, 20% of the population of New York were slaves, totaling about 2,500 people. After a series of fires in 1741, the city became panicked that blacks planned to burn the city in a conspiracy with some poor whites. Historians believe their alarm was mostly fabrication and fear, but officials rounded up 31 blacks and 4 whites, all of whom were convicted of arson and executed. City officials executed 13 blacks by burning them alive and hanged 4 whites and 18 blacks.  In 1754, Columbia University was founded under charter by George II of Great Britain as King's College in Lower Manhattan.  The Stamp Act and other British measures fomented dissent, particularly among the Sons of Liberty, who maintained a long-running skirmish with locally stationed British troops over Liberty Poles from 1766 to 1776. The Stamp Act Congress met in New York City in 1765 in the first organized resistance to British authority across the colonies. After the major defeat of the Continental Army in the Battle of Long Island, General George Washington withdrew to Manhattan Island, but with the subsequent defeat at the Battle of Fort Washington the island was effectively left to the British. The city became a haven for loyalist refugees, becoming a British stronghold for the entire war. Consequently, the area also became the focal point for Washington's espionage and intelligence-gathering throughout the war.  In 1771, Bear Market was established along the Hudson River shoreline on land donated by Trinity Church, and replaced by Washington Market in 1813.  New York City was greatly damaged twice by fires of suspicious origin during British military rule. The city became the political and military center of operations for the British in North America for the remainder of the war and a haven for Loyalist refugees. Continental Army officer Nathan Hale was hanged in Manhattan for espionage. In addition, the British began to hold the majority of captured American prisoners of war aboard prison ships in Wallabout Bay, across the East River in Brooklyn. More Americans lost their lives from neglect aboard these ships than died in all the battles of the war. British occupation lasted until November 25, 1783. George Washington triumphantly returned to the city that day, as the last British forces left the city.  Starting in 1785, the Congress met in New York City under the Articles of Confederation. In 1789, New York City became the first national capital of the United States under the new United States Constitution. The Constitution also created the current Congress of the United States, and its first sitting was at Federal Hall on Wall Street. The first United States Supreme Court sat there. The United States Bill of Rights was drafted and ratified there. George Washington was inaugurated at Federal Hall. New York City remained the capital of the U.S. until 1790, when the role was transferred to Philadelphia.

19th century.

New York grew as an economic center, first as a result of Alexander Hamilton's policies and practices as the first Secretary of the Treasury and, later, with the opening of the Erie Canal in 1825, which connected the Atlantic port to the vast agricultural markets of the North American interior. Immigration resumed after being slowed by wars in Europe, and a new street grid system, the Commissioners' Plan of 1811, expanded to encompass all of Manhattan. Early in the 19th century, the landfill was used to expand Lower Manhattan from the natural Hudson shoreline at Greenwich Street to West Street.  In 1898, the modern City of New York was formed with the consolidation of Brooklyn (until then an independent city), Manhattan and outlying areas. The borough of Brooklyn incorporated the independent City of Brooklyn, recently joined to Manhattan by the Brooklyn Bridge in Lower Manhattan. Municipal governments contained within the boroughs were abolished, and the county governmental functions, housed in Lower Manhattan after unification, were absorbed by the City or each borough.

20th century.

Washington Market was located between Barclay and Hubert Streets, and from Greenwich Street to West Street. It was demolished in the 1960s and replaced by a new Independence Plaza, Washington Market Park and other developments.  Lower Manhattan retains one of the most irregular street grid plans in the borough. Throughout the early decades of the 1900s, the area experienced a construction boom, with major towers such as 40 Wall Street, the American International Building, Woolworth Building, and 20 Exchange Place being erected.  On March 25, 1911, the Triangle Shirtwaist Factory fire in Greenwich Village took the lives of 146 garment workers, which would eventually lead to great advancements in the city's fire department, building codes, and workplace regulations.  Throughout the first half of the 20th century, the city became a world center for industry, commerce, and communication. Interborough Rapid Transit (the first New York City Subway company) began operating in 1904. The area's demographics stabilized, labor unionization brought new protections and affluence to the working class, the city's government and infrastructure underwent a dramatic overhaul under Fiorello La Guardia, and his controversial parks commissioner, Robert Moses, ended the blight of many tenement areas, expanded new parks, remade streets, and restricted and reorganized zoning controls, especially in Lower Manhattan.  In the 1950s, a few new buildings were constructed in Lower Manhattan, including an 11-story building at 156 William Street in 1955. A 27-story office building at 20 Broad Street, a 12-story building at 80 Pine Street, a 26-story building at 123 William Street, and a few others were built in 1957. By the end of the decade, Lower Manhattan had become economically depressed, in comparison with Midtown Manhattan, which was booming. David Rockefeller spearheaded widespread urban renewal efforts in Lower Manhattan, beginning with constructing One Chase Manhattan Plaza, the new headquarters for his bank. He established the Downtown-Lower Manhattan Association (DLMA) which drew up plans for broader revitalization of Lower Manhattan, with the development of a world trade center at the heart of these plans. The original DLMA plans called for the "world trade center" to be built along the East River, between Old Slip and Fulton Street. After negotiations with New Jersey Governor Richard J. Hughes, the Port Authority decided to build the World Trade Center on a site along the Hudson River and the West Side Highway, rather than the East River site.  When building the World Trade Center, 1.2 million cubic yards (917,000 m) of material was excavated from the site. Rather than dumping the spoil at sea or in landfills, the fill material was used to expand the Manhattan shoreline across West Street, creating Battery Park City. The result was a 700-foot (210-m) extension into the river, running six blocks or, covering, providing a riverfront esplanade and over of parks.  Through much of its history, the area south of Chambers Street was mainly a commercial district, with a small population of residents—in 1960, it was home to about 4,000. Construction of Battery Park City, on landfill from construction of the World Trade Center, brought many new residents to the area. Gateway Plaza, the first Battery Park City development, was finished in 1983. The project's centerpiece, the World Financial Center, consists of four luxury highrise towers. By the turn of the century, Battery Park City was mostly completed, with the exception of some ongoing construction on West Street. Around this time, Lower Manhattan reached its highest population of business tenants and full-time residents.  In 1993, the Downtown Lower Manhattan Association (D-LMA), led by Robert Douglass, contributed to a city Planning Department plan calling for the revitalization of Lower Manhattan. The plan included recommended zoning changes, tax incentives to encourage new tenants and the conversion of commercial buildings into apartments. It also called for the creation of a “business improvement district”, The Alliance for Downtown New York, to help spur the area's renewal. Between 1995 and 2014, 15.8 million square feet of office space has been converted to residential or hotel use. As a result, Lower Manhattan's residential population rose from 14,000 to 60,000. The Stonewall riots were a series of spontaneous, violent demonstrations by members of the gay community against a police raid that took place in the early morning hours of June 28, 1969, at the Stonewall Inn in the Greenwich Village neighborhood of Lower Manhattan. They are widely considered to constitute the single most important event leading to the gay liberation movement and the modern fight for LGBT rights.  Since the early twentieth century, Lower Manhattan has been an important center for the arts and leisure activities. Greenwich Village was a locus of bohemian culture from the first decade of the century through the 1980s. Several of the city's leading jazz clubs are still located in Greenwich Village, which was also one of the primary bases of the American folk music revival of the 1960s. Many art galleries were located in SoHo between the 1970s and early 1990s; today, the downtown Manhattan gallery scene is centered in Chelsea. From the 1960s onward, Lower Manhattan has been home to many alternative theater companies, constituting the heart of the Off-Off-Broadway community. Punk rock and its derivatives emerged in the mid-1970s largely at two venues: CBGB on the Bowery, the western edge of the East Village, and Max's Kansas City on Park Avenue South. At the same time, the area's surfeit of reappropriated industrial lofts played an integral role in the development and sustenance of the minimalist composition, free jazz, and disco/electronic dance music subcultures. The area's many nightclubs and bars—though mostly shorn of the freewheeling iconoclasm, pioneering spirit, and do-it-yourself mentality that characterized the pre-gentrification era—still draw patrons from throughout the city and the surrounding region. In the early twenty-first century, the Meatpacking District, once the sparsely populated province of after-hours BDSM clubs and transgender prostitutes, gained a reputation as New York's trendiest neighborhood.

21st century.

On September 11, 2001, two of the four hijacked planes were flown into the Twin Towers of the original World Trade Center, and the towers collapsed. The 7 World Trade Center was not struck by a plane but collapsed because of heavy debris falling from the impacts of planes and the collapse of the North Tower. The other buildings of the World Trade Center complex were damaged beyond repair and soon after demolished. The collapse of the Twin Towers caused extensive damage to surrounding buildings and skyscrapers in Lower Manhattan, and resulted in the deaths of 2,606 people, in addition to those on the planes. Many rescue workers and residents of the area also developed several life-threatening illnesses and some have since died.  Following September 11, Lower Manhattan lost much of its economy and office space but has since rebounded significantly. Private sector employment reached 233,000 at the end of 2016, the highest levels since the end of 2001. This was largely due to growth and diversification in the local workforce with gains in employment sectors like Technology, Advertising, Media and Information, as well as Hotel, Restaurants, Retailing, and Health care. As of 2016, Lower Manhattan's business district is home to approximately 700 retail stores and 500 bars and restaurants.  The Lower Manhattan Development Corporation has consummated plans to rebuild downtown Manhattan by adding new streets, buildings, and office space. The National September 11 Memorial at the site was opened to the public on September 11, 2011, while the National September 11 Museum was officially inaugurated by President Barack Obama on May 15, 2014. As of the time of its opening in November 2014, the new One World Trade Center, formerly known as the "Freedom Tower", is the tallest skyscraper in the Western Hemisphere and the fourth-tallest in the world, at ; while other skyscrapers are under construction at the site.  The Occupy Wall Street protests in Zuccotti Park, formerly known as Liberty Plaza Park, began in the Financial District on September 17, 2011, receiving global attention and spawning the Occupy movement against social and economic inequality worldwide.  On October 29 and 30, 2012, Hurricane Sandy ravaged portions of Lower Manhattan with record-high storm surge from New York Harbor, severe flooding, and high winds, causing power outages for hundreds of thousands of Manhattanites and leading to gasoline shortages and disruption of mass transit systems. The storm and its effects have prompted the discussion of constructing seawalls and other coastal barriers around the shorelines of Manhattan and the New York City metropolitan region to minimize the risk of destructive consequences from another such event in the future.  Lower Manhattan has been experiencing a baby boom, well above the overall birth rate in Manhattan, with the area south of Canal Street witnessing 1,086 births in 2010, 12% greater than 2009 and over twice the number born in 2001. The Financial District alone has witnessed growth in its population to approximately 43,000 as of 2014, nearly double the 23,000 recorded at the 2000 Census.  There are currently 61,000 residents south of Chambers Street and more than 62 percent of the population is between 18 and 44. Lower Manhattan is home to more young professionals than Greenpoint, the East Village, and Downtown Brooklyn and on par with Downtown Jersey City and Williamsburg.  In June 2015, "The New York Times" wrote that Lower Manhattan's dining scene was experiencing a renaissance. Currently, there are 416 casual dining and 129 full-service dining restaurants. "The Village Voice", based at 80 Maiden Lane in the Financial District and historically the largest alternative newspaper in the United States, announced in 2017 that it would cease publication of its print edition and convert to a fully digital venture.  On October 31, 2017, a man drove a pickup truck into the Hudson River Park's bike path between Houston Street and Chambers Street, killing eight people and injuring at least 15. Most of those who were hit were bicyclists. It was the first deadly terrorist attack in Manhattan since 9/11.  Since 2010, a Little Australia has emerged and is growing in the Nolita neighborhood of Lower Manhattan.

Historical sites.

Before the September 11 attacks, the Twin Towers were iconic of Lower Manhattan's global significance as a financial center. The new office towers built since the attack (including One World Trade Center) have transformed the skyline of Lower Manhattan. The 9/11 Memorial & Museum at the former World Trade Center site has become a popular draw for visitors.  The area contains many historical buildings and sites, including Castle Garden, originally the fort Castle Clinton, Bowling Green, the old United States Customs House, now the National Museum of the American Indian, Federal Hall National Memorial, where George Washington was inaugurated as the first U.S. President, Fraunces Tavern, New York City Hall, the Museum of American Finance, the New York Stock Exchange, renovated original mercantile buildings of the South Street Seaport (and a modern tourist building), the Brooklyn Bridge, South Ferry, embarkation point for the Staten Island Ferry, and Trinity Church. Lower Manhattan is home to some of New York City's most spectacular skyscrapers, including the Woolworth Building, 40 Wall Street (also known as the Trump Building), the Standard Oil Building at 26 Broadway, and the American International Building.  Among the commercial districts of Lower Manhattan no longer in existence was Radio Row on Cortlandt Street, which was demolished in 1966 to make way for construction of the former World Trade Center.

Denotation.

"Downtown" in the context of Manhattan, and of New York City generally, has different meanings to different people, especially depending on where in the city they reside. Residents of the island or of The Bronx generally speak of "going" "downtown" to refer to any southbound excursion to any Manhattan destination. A declaration that one is going to "be" "downtown" may indicate a plan to be anywhere south of 14th Street—the definition of downtown according to the city's official tourism marketing organization—or even 23rd Street. The full phrase "Downtown Manhattan" may also refer more specifically to the area of Manhattan south of Canal Street. Within business-related contexts, many people use the term "Downtown Manhattan" to refer only to the Financial District and the corporate offices in the immediate vicinity. For instance, the Business Improvement District managed by the Alliance for Downtown New York defines Downtown as south of Murray Street (essentially South of New York City Hall), which includes the World Trade Center area and the Financial District. The phrase "Lower Manhattan" may apply to any of these definitions: the broader ones often if the speaker is discussing the area in relation to the rest of the city; more restrictive ones, again, if the focus is on business matters or on the colonial and early post-colonial history of the island. As reflected in popular culture, "Downtown" in Manhattan has historically represented a place where one could "forget all your troubles, forget all your cares, and go Downtown," as the lyrics of Petula Clark's 1964 hit "Downtown" celebrate (although Tony Hatch, the songwriter of the track, later clarified that he naively believed Times Square to be "downtown," and was the actual inspiration for the hit single). The protagonist of Billy Joel's 1983 hit "Uptown Girl" contrasts himself (a "downtown man") with the purportedly staid uptown world. Likewise, the chorus of Neil Young's 1995 single "Downtown" urges "Let's have a party, downtown all right."

Economy.

Lower Manhattan is the fourth largest business district in the United States, after Midtown Manhattan, the Chicago Loop, and Washington, D.C. Anchored by Wall Street, New York City functions as the financial capital of the world and has been called the world's most economically powerful city. Lower Manhattan is home to the New York Stock Exchange, on Wall Street, and the corporate headquarters of NASDAQ, at 165 Broadway, representing the world's largest and second largest stock exchanges, respectively, when measured both by overall average daily trading volume and by total market capitalization of their listed companies in 2013. Wall Street investment banking fees in 2012 totaled approximately US$40 billion.  Other large companies with headquarters in Lower Manhattan include, in alphabetical order:  Prior to the September 11 attacks, One World Trade Center served as the headquarters of Cantor Fitzgerald. Prior to its dissolution, the headquarters of US Helicopter were in Lower Manhattan. When Hi Tech Expressions existed, its headquarters were in Lower Manhattan.

Government and infrastructure.

The headquarters of the Port Authority of New York and New Jersey is located in Four World Trade Center of the World Trade Center complex.  The city hall and related government infrastructure of the City of New York are located in Lower Manhattan, next to City Hall Park. The Jacob K. Javits Federal Building is located in Civic Center. It includes the Federal Bureau of Investigation New York field office.  Many New York City Subway routes converge downtown. The largest hub, Fulton Center, was completed in 2014 after a $1.4 billion reconstruction project necessitated by the September 11, 2001 attacks, and involves six separate stations. This transit hub was expected to serve 300,000 daily riders as of late 2014. The World Trade Center Transportation Hub and PATH station opened in 2016. Ferry services are also concentrated downtown, including the Staten Island Ferry at the Whitehall Terminal, NYC Ferry at Pier 11/Wall Street (and Battery Park City Ferry Terminal starting in 2020), and service to Governors Island at the Battery Maritime Building.

Lower Manhattan, also known as Downtown Manhattan or Downtown New York, is the southernmost part of Manhattan, the central borough for business, culture, and government in the City of New York, which itself originated at the southern tip of Manhattan Island in 1624, at a point which now constitutes the present-day Financial District. The population of the Financial District alone has grown to an estimated 61,000 residents as of 2018, up from 43,000 as of 2014, which in turn was nearly double the 23,000 recorded at the 2000 Census.

Lower Manhattan (Downtown Manhattan) je nejjižnější část newyorské čtvrti Manhattan, resp. stejnojmenného ostrova. Území je ohraničeno 14. ulicí nebo až 23. ulicí na severu, řekou Hudson River na západě, přílivovou úžinou zvanou East River na východě a přístavem New York Harbor (též známým jako Upper New York Bay) na jihu.
