It is a development of descriptive characteristics of location, differentiation and shape of wage distribution, but also the development of concentration characteristic of wage distribution. Gross monthly wage of Czech employees represents the variable under research. Emphasis is placed on changes in the development of wage distribution since 2009 in connection with the onset of economic recession. The economic crisis has greatly influenced the development of the wage distribution in the Czech Republic, wage growth virtually stopped at this time. Differences in the development of wage distribution between men and women in the Czech Republic are also under this research. Development of wage distribution has been studied by modelling the distribution. Three-parametric lognormal curves are served as a theoretical probability distribution whose parameters were estimated using the L-moment method of point estimate of parameters. Dependence of gross monthly wage on gender has been the subject of research as well. This dependence was researched using one-way analysis of variance. Forecast of wage distribution of men and women in the Czech Republic for the years 2012 and 2013 is included in this research.展开更多

Whether bisphenol A exposure was associated with circulating sex hormone concentrations was studied. Univariate analysis revealed that the urinary bisphenol A concentration was negatively correlated with the serum levels of luteinizing hormone (B=-0.061, P〈0.0001) and follicle-stimulating hormone (B=-0.086, P〈0.0001) in men, and with the serum levels of follicle-stimulating hormone (B=-0.037, P=0.018) and sex hormone-binding globulin (B=-0.043, P=0.006) in women. However, no significant association was observed between the serum levels of urinary bisphenol A and circulating sex hormone after adjustment for the potential confounders.展开更多

The way that tenure is established and reviews for tenure are conducted need to be based more on a system that allows for the development of the whole individual. The future health of academia rests on the development and refinement of a system that creates a healthy environment for all members of that system. All faculty members cannot and should not be held to standards that were created in another time, which constructed the academic role as a gendered role. Individuals need to consider how we do gender, and how that creates an impact on our organization, academia. A process for equitable review of all participants in the system requires that all individuals be involved in the process of defining the standards for a tenurable professor. Then all voices should and must be represented when we construct how we do tenure so that even minority voices still have their chance to speak. There is a better way to perform the roles we take in academia, there is a better way to perform our gender in this setting, and from recognizing this we can then move to a better way to do all this that is academia.展开更多

Elevated haemoglobin values (EE) are associated with chronic mountain sickness, a condition reflecting the lack of adaptation to HA. According to current data, native men from regions of HA are not adequately adapted to live at such altitudes if they have elevated serum testosterone levels. This seems to be due to an increased conversion of dehydroepiandrosterone sulphate (DH EAS) to testosterone. Men with erythrocytosis at HAs show higher serum androstenedione levels and a lower testosterone/androstenedione ratio than men with EE, suggesting reduced 17beta-hydroxysteroid dehydrogenase (17beta-HSD) activity. Lower 17beta-HSD activity via A4-steroid production in men with erythrocytosis at HA may protect against elevated serum testosterone levels, thus preventing EE. The higher conversion of DHEAS to testosterone in subjects with EE indicates increased 17beta-HSD activity via the A5-pathway. Currently, there are various situations in which people live (human biodiversity) with low or high haemoglobin levels at HA. Antiquity could be an important adaptation component for life at HA, and testosterone seems to participate in this process.展开更多

In a recent study published by the National Academy of Science, USA it was shown that month of birth is related to longevity. The aim of this study was to check the month of birth distribution in a great group of AMI patients of both gender, one of the great killers in the developed countries, to check the mentioned paradigm of month of birth and longevity. Methods & Patients: Patients admitted to Cardiology Departments of a tertiary University Hospital in Kaunas, Lithuania with AMI at years 1990-2010 (n-22047) were studied. Month of birth of these patients, total and both gender were checked. Monthly, quarterly and trimester comparison were done. Statistical differences established using t-Student test and distribution by percents of the yearly months of birth. Results: It was a significant difference in the month of birth of the studied AMI population. January and first quarter and trimester born patients were more often in the studied AMI patients group. The higher morbidity by Cardiovascular diseases can be a significant ingredient in the structure of population longevity. Possible mechanisms explaining our findings are discussed. Conclusion: In the AMI population people born in January, first quarter or trimester of the year are dominating in both gender groups. The results of this study can be an additional confirmation of the paradigm about links between month of birth and longevity.展开更多

Moreover, significant sex differences were found in cardiac structure, function, pathophysiology, presentation, treatment, and outcome of IHD. The presence of unique risk factors such as exposure to menarche and pregnancy, more anemia, hypertension, and autoimmune disorders in women have recently received attention. Ischemic symptoms are more indefinite and vague in women compared to men as well as a delay in diagnosis, treatment, and worse outcomes compared to men. Women usually receive less evidence-based treatment and intervention, with less concern on preventive health care. Clinical trials primarily recruit male patients and women are underrepresented. Without any correct diagnosis, treatment, and prevention, these problems are accumulated and continue up to older age. Accordingly, with the belief of longer life in women and the increased prevalence of IHD with aging, it will become an important public health problem and concern in the future. This narrative review aimed to provide an overview of some of the differences between the two genders in terms of IHD with paying more attention to practical points.展开更多

In this analysis, the impact of Confucianism on family norms,specifically, on labour division, decision making, reproductive behaviours and patterns of support for the elderly within the family sphere are elaborated based on the information from field investigations. It is anticipated that with the far-reaching family planning programme and modernization drive, the traditional ideas will undergo a fundamental change.展开更多

It turned out that the majority of surveyed subjects were characterized by deformation of element status demonstrated by excess and deficit of the basic essential elements of different degrees of manifestation. Deficit of Co (68% of surveyed people), Mg (67%), Ca (64%), Cu (47%), K (46%), Zn (44%), I (41%), Na (33%), P (27%) and Se (24%) was typical for female subjects as well as excess of Si (28%), Zn (22%) and P (20%). Male residents were characterized by deficit of Co (81%), Ca (66%), Mg (65%), I (50%), Cu (37%), K and Na (27%) and excess of Zn (41%). In individual cases it was noted excess concentration of nominally essential and toxic elements in both examined groups. They were: A1, As, Cd, Li, Ni, Pb, Sn, V and B. While analyzing of medians of chemical concentration it was stated reliable sex-related differences (P 〈 0.05): content of Ca, Mg and Mn was higher in hair samples of women, and content of As, B, Cd, Cr, K, Li, Na, P, Pb and V, on the contrary, was higher in male samples.展开更多

文摘Populations living at high altitudes (HAs), particularly in the Peruvian Andes, are characterized by a mixture of subjects with erythrocytosis (16 g dl-1〈haemoglobin (Hb)≤21 gdl-1) and others with excessive erythrocytosis (EE) (Hb〉21 g dl-1). Elevated haemoglobin values (EE) are associated with chronic mountain sickness, a condition reflecting the lack of adaptation to HA.
