Little is known regarding the profiles of whole body donors in Muslim majority countries where donation is scarce. Therefore, this study aims to profile registered donors in Turkey by means of a survey. The explored data could be used to improve ongoing campaign efforts and ethical practices such as commemoration services. Registered donors of the donation programs at the two faculties of medicine of Istanbul University were compared with the national population and a cluster analysis was performed to reveal any concealed sub-groups. Data from 188 respondents were analyzed. The majority of registered donors were married (42%), male (65.4%), aged over 50 years (76%), held a tertiary education degree (49.7%), and were irreligious (58.5%). Cluster analysis revealed two groups with significantly different educational levels, marital statuses, and religious choices. Regarding whether their bodies could be used for education or research, the majority (64.5%) of the respondents left the decision to the anatomy department. Similarly, 73.8% approved indefinite use of their organs, body parts and/or skeletons. The respondents were also willing to share their medical history (94.2%) and personal information (81.6%) if needed. Motivational themes for body donation including usefulness, impermanence, religion, awareness, and kinship were devised after a thematic analysis. Among the respondents, 56.5% were registered organ donors and 63.3% were frequent blood donors. The results of this study provide data that may help revising informed consent forms, developing and implementing thanksgiving ceremonies, and selecting additional targets for supporting body donation campaign activities such as organ and blood donation units. 相似文献

This paper seeks to trace the development of graduate studies in basic sciences in Turkish universities from origins to the present day. The study includes a sketch of the historical background of higher education from its start in medieval madrasahs and Istanbul Darulfunun (The House of Sciences), to the transition into present-day university education, i.e., to the beginnings of modern graduate study and the emergence of new universities. Empirical statistics are given to substantiate the rapid growth of graduate study and of the number of degrees produced since the 1980s. The mean number of Ph.D. Degrees per year has increased from a few in a single university in the 1930s to nearly a hundred in today's twenty seven universities in Turkey in the 1980s. Finally, a quantitative overview of the growth trends in graduate study in basic sciences as well as an assessment of the present degree productivity of Turkish universities are presented. 相似文献

The primary aim of this study was to investigate the correlation between game addiction and academic achievement. The secondary aim was to adapt a self-report instrument to measure game addiction. Three hundred and seventy high school students participated in this study. Data were collected via an online questionnaire that included a brief explanation of the aim of the study, demographical questions, game addiction scale (GAS) and the grade point average of the current year. The GAS had two forms: (i) 21-item and (ii) 7-item. Game addiction and academic achievement were negatively correlated but this correlation was not supported by regression and structural equation modelling analyses. The present study primarily suggests that there may be a negative correlation between game addiction and academic achievement; however, this correlation may be qualified as negligible. In addition, the two forms of the GAS were adapted for Turkish language with reliability and validity to measure computer and video game addiction in adolescents as promising instruments. 相似文献

ABSTRACTThe present study aims to examine the leadership research in higher education in order to shed light on its development during the last two decades by revealing the evolving trends in research on leadership in higher education, the most prominent scholars working on related research, the most popular topics in related research, and the countries in which the related studies are based. Bibliometric method was employed in the analysis of the original research and review papers published in five prominent higher education journals between 1995 and 2014: Higher Education, Research in Higher Education, Studies in Higher Education, The Journal of Higher Education and The Review of Higher Education. The results of this bibliometric analysis show that the majority of the related articles come from three countries: the U.S.A., the UK and Australia. It is also found that the leadership research in higher education is still very scarce and has not shown any meaningful increase during the last two decades. In addition, content analysis is used to provide more in-depth information about the topical focus, purpose and methodology of the selected articles. The results of content analyses are discussed in detail, and suggestions for the future research are provided. 相似文献

The purpose of this study was to investigate the differences among schools using student responses in the Trends in Mathematics and Science Study–1999 (TIMSS‐99) data. Schools were classified into two groups based on eighth grade students' overall achievement in science. Two different discriminant function analyses were performed to distinguish high‐ and low‐performing schools, based both on classroom practices and factor structures (student‐centered activities, teacher‐centered activities, attitudes toward technology use, socioeconomic status [SES], and doing well in science). The results indicate that there were significant differences between the two classifications of schools on ten variables regarding classroom practices and activities, and 29 variables regarding classroom practices, attitudes toward science, use of the computer and overhead projector (OHP), parental background characteristics, and need to do well in science. Contrary to general expectations, technology use (computer, OHP, etc.) was found to be negatively related to science achievement. Teachers should be trained on how to use technology in their classrooms. Turkey recently revised its curriculum to a student‐centered approach and this might increase students' ability to transfer knowledge into real life. Teachers and schools should pay more attention to SES effects. Teachers should also work toward building students' confidence in science. © 2007 Wiley Periodicals, Inc.

A Chebyshev collocation method, an expansion method, has been proposed in order to solve the systems of higher-order linear integro-differential equations. This method transforms the IDE system and the given conditions into the matrix equations via Chebyshev collocation points. By merging these results, a new system which corresponds to a system of linear algebraic equations is obtained. The solution of this system yields the Chebyshev coefficients of the solution function. Some numerical results are also given to illustrate the efficiency of the method. Moreover, this method is valid for the systems of differential and integral equations. 相似文献

Introduction
Extremely high glucose concentrations have been shown to interfere with creatinine assays especially with Jaffe method in peritoneal dialysate. Because diabetes is the fastest growing chronic disease in the world, laboratories study with varying glucose concentrations. We investigated whether different levels of glucose spiked in serum interfere with 21 routine chemistry and thyroid assays at glucose concentrations between 17-51 mmol/L.Materials and methods
Baseline (group I) serum pool with glucose concentration of 5.55 (5.44-5.61) mmol/L was prepared from patient sera. Spiking with 20% dextrose solution, sample groups were obtained with glucose concentrations: 17.09, 34.52, and 50.95 mmol/L (group II, III, IV, respectively). Total of 21 biochemistry analytes and thyroid tests were studied on Abbott c8000 and i2000sr with commercial reagents. Bias from baseline value was checked statistically and clinically.Results
Creatinine increased significantly by 8.74%, 31.66%, 55.31% at groups II, III, IV, respectively with P values of < 0.001. At the median glucose concentration of 50.95 mmol/L, calcium, albumin, chloride and FT4 biased significantly clinically (-0.85%, 1.63%, 0.65%, 7.4% with P values 0.138, 0.214, 0.004, < 0.001, respectively). Remaining assays were free of interference.Conclusion
Among the numerous biochemical parameters studied, only a few parameters are affected by dramatically increased glucose concentration. The creatinine measurements obtained in human sera with the Jaffe alkaline method at high glucose concentrations should be interpreted with caution. Other tests that were affected with extremely high glucose concentrations were calcium, albumin, chloride and FT4, hence results should be taken into consideration in patients with poor diabetic control.Key words: assay interference, glucose interference, preanalytical phase, creatinine, Jaffe kinetic assay, thyroid function tests 相似文献10.
