Therefore, education of sociologists requires, among other things, training in statistical methods applicable in data processing and analysis in sociological research. Then the research continues with a comparative analysis of the curricula of undergraduate academic studies of sociology, and especially the presence of statistics teaching in them, in the Republic of Serbia and the neighbouring countries. Different programs of the Department of Sociology of the Faculty of Philosophy in Novi Sad are analyzed together with the results of the students＇ evaluations for the academic years 2007/2008 and 2009/2010.展开更多

It necessitates a revolution of ecological observation technology and a long-term accumulation of scientific data. The ecosystem flux tower observation technology is the right one to meet this requirement. However, the unique advantages and potential values of global-scale flux tower observation are still not fully appreciated. Reviewing the development history of global meteorological observation and its scientific contributions to the society, we can get an important enlightenment to re-cognize the scientific mission of flux observation.展开更多

Well-known estimators with high breakdown points were compared using simulated data. Mean success rates (MSR) were computed and used as comparison criteria. The results showed that the least median of squares (LMS) and least trimmed squares (LTS) were the most successful methods for data that included leverage points, masking and swamping effects or critical and concentrated outliers. We recommend using LMS and LTS as diagnostic tools to classify outliers, because they remain robust even when applied to models that are heavily contaminated or that have a complicated structure of outliers.展开更多
