SİSTEMATİK RİSKİN KONAKLAMA İŞLETMELERİNİN KARLILIK ORANLARI ÜZERİNDEKİ ETKİSİNİN ÖLÇÜLMESİ (MARMARİS ALTINYUNUS TURİSTİK TESİSLERİ A.Ş ÖRNEĞİ)
As is known, the risk of financial sense is defined as the difference between expected return and actual return. The part of risk that cannot be mitigated by diversification is evaluated as part of systematic risk and there is a focus in this area. These positive impacts of systematic risk factors, known to have positive impacts on the profitability of firms. if managed well the systematic risk factors vary on the basis of the sector and the company. Although there are many components, it is possible to analyze and evaluate the total effect of interest rate, inflation and exchange rate, which are the major systematic risk factors with the help of the beta coefficient. In this study, the effect of systematic risk on profitability have been analyzed and evaluated on the financial statements of  Marmaris Altinyunus Touristic Facilities Inc., which is a public limited company and one of the hospitality industry establishments in Marmaris, Turkey. The application side of the study comprises of the regression and correlation analyses between the beta coefficients and the profitability ratios obtained from sample data taken from the entity's financial statements.
Hotel Value Trends
Analysts have worked to model the relationship of supply and demand that creates hotel value. The Hotel Valuation Index, developed by HVS International, is a sophisticated model that now comprises 46 U.S. markets. In the aabsence of major economic disruptions, hotel demand grows at a relatively steady rate. Consequently, supply additions have a measurable effect on lodging-property values. Supply additions occur principally when developers and investors perceive that building new rooms is less expensive than purchasing existing properties. In recent years investors have been able to purchase hotels at prices below replacement value. The HVI shows that that phenomenon is ending, as the value of existing rooms will exceed replacement cost for most market segments. After ten years of tracking major U.S. markets, HVS can project future valuation levels, based on expected supply trends and a relatively stable economy.
Genetics of the phenotypic evolution in sheep: a molecular look at diversity-driving genes
Background After domestication, the evolution of phenotypically-varied sheep breeds has generated rich biodiversity. This wide phenotypic variation arises as a result of hidden genomic changes that range from a single nucleotide to several thousands of nucleotides. Thus, it is of interest and significance to reveal and understand the genomic changes underlying the phenotypic variation of sheep breeds in order to drive selection towards economically important traits. Review Various traits contribute to the emergence of variation in sheep phenotypic characteristics, including coat color, horns, tail, wool, ears, udder, vertebrae, among others. The genes that determine most of these phenotypic traits have been investigated, which has generated knowledge regarding the genetic determinism of several agriculturally-relevant traits in sheep. In this review, we discuss the genomic knowledge that has emerged in the past few decades regarding the phenotypic traits in sheep, and our ultimate aim is to encourage its practical application in sheep breeding. In addition, in order to expand the current understanding of the sheep genome, we shed light on research gaps that require further investigation. Conclusions Although significant research efforts have been conducted in the past few decades, several aspects of the sheep genome remain unexplored. For the full utilization of the current knowledge of the sheep genome, a wide practical application is still required in order to boost sheep productive performance and contribute to the generation of improved sheep breeds. The accumulated knowledge on the sheep genome will help advance and strengthen sheep breeding programs to face future challenges in the sector, such as climate change, global human population growth, and the increasing demand for products of animal origin.
