ABSTRACTThe aim of this research was to examine the levels of burnout syndrome dimensions in special education teachers and correlations with some socio-demographic characteristics, job characteristics, and levels of assertiveness. The research included 225 special education teachers from Serbia (82% were women, 18% were men, with the average age of 42.51 ± 9.23 years). Research instruments included Maslach Burnout Inventory, Rathus Assertiveness Schedule, and a socio-demographic questionnaire. There were differences in all burnout dimensions in relation to types of students’ special needs. Higher levels of burnout symptoms were observed in teachers working with children with motor skill disorders. The assertiveness scores had a significant negative correlation with emotional exhaustion and depersonalisation, and a positive correlation with a lack of accomplishment. The results obtained may help in the planning of the adequate preventative measures for improving the mental health of those professionals. 相似文献

The purpose of this research paper is to identify the factors affecting the effectiveness of Moodle from the students' perspective. The research hypotheses derived from the suggested extended Seddon model have been empirically validated using the responses to a survey on e-learning usage among 255 users. We tested the model across higher education institutions in Serbia, Lithuania, and Bosnia and Herzegovina. These responses have been examined through partial-least squares. The obtained results strongly support 16 of the 23 research hypotheses for the proposed e-learning model. We defined eight factors (behavioral intention to use in the future, communicativeness, format, information quality, performance outcome, perceived usefulness, satisfaction and system quality) in the initial theoretical e-learning model. Unexpectedly, system and information quality did not influence satisfaction, while communicativeness had the highest significant impact on performance outcome. Satisfaction had a significant effect on behavior intention and accounted for 68.4% of the variance in this area. The findings offer an insight into those factors that are likely significant antecedents for planning and implementing a Moodle e-learning system to enhance student-learning effectiveness. 相似文献

The aim of this study was to examine whether motivational‐emotional variables such as intrinsic orientation toward schoolwork, Mathematics anxiety, academic self‐esteem, attribution of success and failure in Mathematics and situational interest in Mathematics could differentiate different groups of mathematically gifted pupils. The research was based, theoretically, on an interactional model of giftedness. The sample consisted of 147 selected primary school pupils (9‐10 years of age) who were assigned to the following groups for comparison: mathematically gifted achievers (n = 31), mathematically gifted under‐achievers (n = 31) and mathematically non‐gifted pupils (n = 85). The results of a discriminant analysis show that the gifted pupils differ from the non‐gifted ones in attaining higher levels of intrinsic orientation toward Mathematics, lower Mathematics anxiety, lower attribution of success to external factors and effort, as well as in lower attribution of failure to external factors and abilities. Also, gifted achievers have lower attribution of success to effort than gifted under‐achievers and non‐gifted pupils. 相似文献

Phlebotomy is one of the most complex medical procedures in the diagnosis, management and treatment of patients in healthcare. Since laboratory test results are the basis for a large proportion (60–80%) of medical decisions, any error in the phlebotomy process could have serious consequences. In order to minimize the possibility of errors, phlebotomy procedures should be standardised, well-documented and written instructions should be available at every workstation. Croatia is one of the few European countries that have national guidelines for phlebotomy, besides the universally used CLSI (Clinical Laboratory Standards Institute) H3-A6 Procedures for the Collection of Diagnostic Blood Specimens by Venipuncture; approved Standard-Sixth Edition (CLSI, 2007) and WHO (World Health Organization) guidelines on drawing blood: best practices in phlebotomy (WHO, 2010). However, the growing body of evidence in importance of preanalytical phase management resulted in a need for evidence based revision and expansion of existing recommendations.The Croatian Society for Medical Biochemistry and Laboratory Medicine, Working Group for the Preanalytical Phase issued this recommendation. This document is based on the CLSI guideline H3-A6, with significant differences and additional information. 相似文献

This article analyses how political preferences, which are co-determined by the beliefs of decision-makers and influences of interest groups and the general public, affect the decisions to maintain or cut public funding for tertiary education during the economic crisis. Our sample included 29 European countries which we divided into two groups depending on the level of public funding for tertiary education before the crisis, which we used as a measure of revealed political preferences. We then observed the differences in changes in public tertiary education funding during the crisis between these two groups of countries using five different indicators. Three of the five indicators show that countries with a stronger political preference for tertiary education public funding cut their spending on tertiary education to a lesser extent (or even increased spending) during the economic crisis. 相似文献

A simple apparatus for an experiment often performed during introductory lectures on free fall is described. Collected data of the free fall times are given and the standard calculation of the acceleration of free fall g including error evaluation is presented. The obtained value for g is compared to values given by International Gravity Formula, and to experimental results for the location in Zagreb, where this experiment is performed, as well as values found in the literature. Calculations of corrections and contributions due to resistive forces of the medium, both linear and quadratic in velocity, as well as buoyancy and inertial forces in non-inertial reference frames are included and thoroughly discussed. 相似文献

Hypersecretion of prolactin by lactotroph cells of the anterior pituitary may lead to hyperprolactinemia in physiological, pathological and idiopathic conditions. Most patients with idiopathic hyperprolactinemia may have radiologically undetected microprolactinomas, but some may present other causes of hyperprolactinemia described as macroprolactinemia. This condition corresponds to the predominance of higher molecular mass prolactin forms (big-big prolactin, MW > 150 kDa), that have been postulated to represent prolactin monomer complexed with anti-prolactin immunoglobulins or autoantibodies. The prevalence of macroprolactinemia in hyperprolactinemic populations between 15-46% has been reported. In the pathophysiology of macroprolactinemia it seems that pituitary prolactin has antigenicity, leading to the production of anti-prolactin autoantibodies, and these antibodies reduce prolactin bioactivity and delay prolactin clearance. Antibody-bound prolactin is big enough to be confined to vascular spaces, and therefore macroprolactinemia develops due to the delayed clearance of prolactin rather than increased production. Although the clinical symptoms are less frequent in macroprolactinemic patients, they could not be differentiated from true hyperprolactinemic patients, on the basis of clinical features alone. Although gel filtration chromatography (GFC) is known to be the gold standard for detecting macroprolactin, the polyethylene glycol precipitation (PEG) method has offered a simple, cheap, and highly suitable alternative. In conclusion, macroprolactinemia can be considered a benign condition with low incidence of clinical symptoms and therefore hormonal and imaging investigations as well as medical or surgical treatment and prolonged follow-up are not necessary. 相似文献
