The relationship of entropy‐related measures to money information
The specific purpose of this paper is to trace the development of entropy-related thought from its thermodynamic origins through its organizational and economic applications to its relationship to money information. That trace reveals that existing entropy measures are of states or changes in states that are caused by energy processes. We propose that entropy may as well be conceived as entropic process. The social emergent specific exchange value provides a metric by which entropic process may be quantified. The analysis connects the traditional state-oriented entropy measures to measures of entropic process in social systems. In doing so, the character of exchange-based societies and the function of money information within them are elaborated. Copyright © 2008 John Wiley & Sons, Ltd.
Criticality, Entropy and Conflict
Power‐law distributions are ubiquitous in the natural and social worlds and also characterize the intensity of intrastate conflicts. One of the most convincing approaches to explain the origin of power laws is the so‐called forest‐fire model, which is based on the notion of self‐organized criticality. In order to make this model more fruitful for social science, its components require a deeper theoretical specification. We turn to general systems theory and the conception of entropy (uncertainty, insecurity and disorder) and its conceptual complement, negentropy. We argue that intrastate conflict is an ‘eruptive’ form of ‘social fissioning’: an evolutionary mechanism whereby sharp friend–foe differences and rigid within‐group conformity are created, increasing the certainty of social interactions. In intrastate conflicts, the political system burdens the economic and cultural systems with entropy and extracts negentropy resources from them. This process is characterized by discontinuous outbursts of entropy, which collectively follow a power law. © 2018 John Wiley & Sons, Ltd.
The Epidemiology and Risk Factors for Nosocomial Catheter-Associated Bacteriuria Caused by Coagulase-Negative Staphylococci
Abstract Studies of the risk factors for bacteriuria associated with the use of temporary indwelling urinary catheters have focused on gram-negative bacilli and enterococci, the predominant causes of nosocomial urinary tract infection. During a prospective study of 747 catheterized patients, bacteriuria with ≥1,000 bacteria/mL were found in 96 patients. Coagulase-negative staphylococci (CNS) accounted for 19% of the episodes of bacteriuria, and S. epidermidis was the most frequent species of CNS. Significant risk factors for bacteriuria were a positive meatal culture for CNS, non-surgical illness, and no antibiotic therapy during catheterization. In contrast to the results of this and earlier studies that females were at greater risk factor for catheter-associated bacteriuria with gram-negative bacilli and enterococci, this was not a risk factor for acquisition of CNS. Possibly this is due to the more similar prevalence of meatal colonization with CNS of males and females compared to the striking difference in prevalence of meatal colonization with gram-negative bacilli and/or enterococci of males and females.
