This article provides a panoramic view of research findings on social inequalities in access to higher education in Croatia since the 1960s, guided by the question of what has changed in the findings. Our review shows that there is stark continuity over the last five decades: students from better educated family backgrounds tend to be overrepresented in higher education; students from better educated and white-collar family backgrounds are more likely to enrol in academic as opposed to professional study courses; students at one Croatian university in particular stand out in terms of their more privileged social background; and medicine seems to be the prime academic field for observing social reproduction. We note that these persistent findings run parallel to a dramatically changing political, economic and social context in Croatia, including transformations in the 1990s resulting from social ownership of the means of production to widespread private ownership, as well as transformations from a one-party political system to the establishment of a multi-party political system. The article maps possible theoretical explanations for the resilience of social inequalities in access to higher education in the context of dynamic times. It also questions the role of educational policies in this process.  相似文献   

Facebook Versus Moodle in Practice

Very few research papers and case studies have shown successful integration of both Facebook and Moodle in the educational experience of students. This study sought to evaluate the educational benefits of the increasingly popular Facebook—which plays an important role in students’ social life as well as their academic life—and to compare it with the widely used course management system Moodle. In this study, the authors surveyed students of the University of Belgrade’s Faculty of Organizational Science in Serbia on their attitude toward Facebook and Moodle as productive online tools for teaching and learning. An analysis of the results was carried out using the SPSS software package. The results of this research answer the question of whether or not using Facebook as an educational tool is more effective than using Moodle and how it affects students’ everyday learning activities.  相似文献   

Is an integrative laboratory algorithm more effective in detecting alpha-1-antitrypsin deficiency in patients with premature chronic obstructive pulmonary disease than AAT concentration based screening approach?

Introduction:

Alpha-1-antitrypsin deficiency (AATD), genetic risk factor for premature chronic obstructive pulmonary disease (COPD), often remains undetected. The aim of our study was to analyse the effectiveness of an integrative laboratory algorithm for AATD detection in patients diagnosed with COPD by the age of 45 years, in comparison with the screening approach based on AAT concentration measurement alone.

Subjects and methods:

50 unrelated patients (28 males/22 females, age 52 (24–75 years) diagnosed with COPD before the age of 45 years were enrolled. Immunonephelometric assay for alpha-1-antitrypsin (AAT) and PCR-reverse hybridization for Z and S allele were first-line, and isoelectric focusing and DNA sequencing (ABI Prism BigDye) were reflex tests.

Results:

AATD associated genotypes were detected in 7 patients (5 ZZ, 1 ZM_malton, 1 ZQ0_amersfoort), 10 were heterozygous carriers (8 MZ and 2 MS genotypes) and 33 were without AATD (MM genotype). Carriers and patients without AATD had comparable AAT concentrations (P = 0.125). In majority of participants (48) first line tests were sufficient to analyze AATD presence. In two remaining cases reflex tests identified rare alleles, M_malton and Q0_amersfoort, the later one being reported for the first time in Serbian population. Detection rate did not differ between algorithm and screening both for AATD (P = 0.500) and carriers (P = 0.063).

Conclusion:

There is a high prevalence of AATD affected subjects and carriers in a group of patients with premature COPD. The use of integrative laboratory algorithm does not improve the effectiveness of AATD detection in comparison with the screening based on AAT concentration alone.  相似文献   

Sliding manifold design for linear systems with unmatched disturbances     

Boban Veselić  Branislava Draženović  Čedomir Milosavljević 《Journal of The Franklin Institute》2014

This paper offers an efficient sliding manifold design method that minimizes the impact of unmatched disturbances onto SM dynamics and system accuracy. System sensitivity upon unmatched constant or slowly varying external disturbance vector is evaluated by the steady-state dependent criterion function. An infinite set of sliding manifolds that minimize the chosen optimization criterion is determined and a way of selecting a manifold out of that set that provides adopted SM dynamics is suggested. The proposed approach has been demonstrated on numerical examples and verified by simulations.  相似文献
