In 1950s, the concept of brain death, which began to be discussed primarily in terms of medicine and then in terms of religion, law, and ethics, became a central topic in all world countries as it was an early diagnosis of death. Despite the fact that brain death (BD) diagnosis is of importance for benefitting from organ and tissue transplantation of patients in the world, the literature still involves no bibliometric studies that made a holistic evaluation of the publications about this issue. The present study aims to investigate the top-cited articles about BD published between 1980 and 2018, identify the citation collaboration of the journals, demonstrate the collaboration between the countries, define the relationship between organ transplantation and BD, and reveal the latest developments and trend topics about this issue. In addition, this study aims to investigate the relationship between religions of countries and brain death publication productivity. Documents for bibliometric analysis were downloaded from Web of Science. The literature search was performed using the keywords “brain death/dead” during 1980–2018. The correlations between gross domestic product (GDP), Human Development Index (HDI) and publication productivity of the countries on BD were investigated with Spearman’s correlation coefficient. There was a high-level, statistically significant correlation between the number of publications and GDP, and HDI and the number of publications about BD (r = 0.761, p < 0.001; r = 0.703, p < 0.001). The USA was the top country in terms of publication productivity, which was followed by developed countries such as Germany, Japan, France, and Spain. However, the contribution of the undeveloped or developing countries such as China, Brazil, Turkey, Iran, and South Africa was found to be considerably important. While many people in the world die with undamaged organs, many other people die needing those organs. Therefore, it is considered that the collaborations and thus multidisciplinary studies about BD should be increased in the world countries, and the countries should be involved in bigger collaborations instead of little clusters. Especially, Muslim countries should be encouraged to do research and publish studies about the issues of brain death and organ transplantation.

In the present study, we examined the impact of the interaction of environmental and task-induced attentional focus on time perception, specifically awareness of the time flow. We tested 48 participants in either a natural or urban setting over three 25- to 35-min sessions. We manipulated the within-subjects factor task by means of two tasks—one requiring directed attention on the task itself, the other undirected attention on the environment—alongside a control condition with no specific task. We measured time awareness, passage of time judgments, felt time judgments, and estimated time as dependent variables. For time awareness, we found an interaction between environment and task: in the natural environment, only a task requiring directed attention reduced time awareness; whereas, in the urban environment, both tasks reduced time awareness compared to the control condition. The results suggest that natural environments increase time awareness unless we focus our attention on a task.  相似文献

Despite the historical trend in all Western societies to increase educational participation irrespective of students' social origin, the correlation between parents' education and socio-economic status and the educational outcomes of their offspring remains a rather universal phenomenon. Although comparative studies have consistently found this association in various nations which differ in many ways in their educational systems, little is known about the mechanism behind this effect. Drawing on the assumption that career decision points are the major gateway for social background influences, we assume that similarities, as well as differences in the structure of the correlation between parents' socioeconomic background and students' school success, can be explained. Using two longitudinal data sets from the United States (N=1425) and Germany (N=1755) covering the school careers from Grade 7 to Grade 10, the analyses supported the hypothesis that (a) achievement information is the best predictor of career relevant decisions in both nations, (b) parents' background variables are independent additional predictors of career decision but not for actual learning progress, and (c) the assumed accumulation process of social background influences is more pronounced in the German than in the U.S. school system.  相似文献
