We hypothesised that resiliency may protect adolescents against risky behaviours, and that both the practicing of sports, and gender are moderating variables in relationships between resiliency and risky behaviours. The study included 18-year-old pupils from a selection of secondary schools (n = 556). A total of 188 individuals practiced competitive sports and the remaining 368 participants were non-athletes. The participants were examined with the Resiliency Assessment Scale for Children and Adolescents (SPP-18) and with a survey containing questions and statements related to high-risk “experiments with adulthood”. Adolescent athletes showed higher levels of resiliency than their peers. The power of the “Determination and Persistence in Action” effect on “Alcohol” scale differed significantly between male athletes and male non-athletes. Only in the athletes groups were higher scores on this scale reflected by lower values on the “Drugs” scale. Moreover, it is possible to observe differences in undertaking risky behaviour between male and female athletes. The analysis of risky sexual behaviour suggests that sport is a risk factor for men, and a protective factor for women. These data suggest that consistent prophylactic and psycho-educative activities, with a special attention to differences between genders, should be provided to all the adolescents, irrespective of their sport performance levels.  相似文献

Purpose

Metalloproteinases are a key component of the pathogenesis of abdominal hernias. Obesity is considered a risk factor in herniogenesis and hernia recurrence. The aim of this study was to evaluate the serum concentrations of metalloproteinase-2 (MMP-2), MMP-9, MMP-13, and adiponectin in morbidly obese and nonoverweight controls.

Materials and methods

The participants were recruited from among patients undergoing bariatric and non-bariatric surgery and divided into two groups: I (body mass index (BMI)≥35 kg/m2, n=40) and II (BMI<25 kg/m2, n=30). Serum concentrations of MMP-2, MMP-9, MMP-13, and adiponectin were measured using enzyme-linked immunosorbent assay (ELISA).

Results

A statistically significant difference between groups was observed for MMP-2 concentration. The median MMP-9 concentration was higher in the obese group, but the difference was not statistically significant. Median MMP-13 concentrations did not differ between groups. Serum adiponectin concentration was insignificantly higher in the non-obese group.

Conclusions

The elevated serum MMP-2 and MMP-9 concentrations in obese individuals may be related to the higher incidence of incisional hernias in this population.

The goal of this work is to better understand the institutional changes in the educational systems of the Czech Republic, Hungary, Poland and Slovakia. We demonstrate that the educational reforms implemented during the transformation introduced very different institutional arrangements in the four countries, despite the fact that their systems shared many common characteristics at the beginning of the 1990s. Differences between the national approaches to educational reforms are particularly reflected in the modes of education decentralisation, the level of school autonomy, accountability and funding mechanisms. We believe that different institutional arrangements may have contributed to the divergent achievements of the Czech Republic, Slovakia, Hungary and Poland in the PISA programme.  相似文献

The article forms an analysis of the religious discrimination discourse in Polish public schools, with special attention paid to the culturally specific, Polish understanding of the notion of religious discrimination. The introductory part presents the concept of religious discrimination as present in anti-discriminatory policies. The following part outlines the Polish system of religious education and its relation to the religious discrimination. Studies on religious discrimination in Poland are presented and discussed. Important context is supplied by a presentation of two recent cases of religious discrimination in Polish public schools, and the actions undertaken by the Freedom from Religion Foundation. Authors of the article point out the important influence of cultural context on the perception of religious discrimination. The attention is drawn to the seemingly homogenous environment of the Polish school and of the discriminative discourse used in political and social debates. The analysis shows that the presence of religion as a subject in Polish schools remains a cause of conflict between the religious and atheist citizens, a conflict in which concepts of religious discrimination and religious freedom are used as arguments by both sides.  相似文献

There is no need nowadays to convince people that modern education cannot function properly without the help of scientific research, and especially of pedagogical research. It is true that there still appear many pedagogical works inflated by wind, as Comenius expressed it more than three hundred years ago, and these publications may even acquire a temporary popularity. But the general trend towards the development of pedagogy as a discipline based on research has been established for quite some time and is constantly gaining strength in the developed countries. Concurrently, pedagogical disciplines have had increasing influence on the development of education.The question of how these disciplines have developed in Poland and how they have influenced the educational system calls for a broader review, such as to allow one to draw conclusions on how to harmonise more effectively the domain of educational research with that of education. Such a review is the aim of the present paper. The following issues are considered: the functions of educational research, the kinds of educational investigations conducted in Poland, ways of disseminating their findings, and the organisation of research in Poland. The paper ends with a discussion of some of the more important conclusions reached.
Zusammenfassung Heutzutage ist es nicht mehr nötig, viele Worte darüber zu verlieren, daß ein modernes Bildungswesen ohne Unterstützung durch wissenschaftliche, insbesondere pädagogische Forschung nicht richtig funktionieren kann. Zwar erscheinen immer noch viele pädagogische Arbeiten, die vom Wind aufgeblasen sind, wie sich Comenius vor über 300 Jahren ausdrückte, und diese können sogar zeitweilig grossen Anklang finden. Aber der allgemeine Trend, die Pädagogik als eine auf Forschung beruhende Disziplin anzusehen, besteht seit längerer Zeit und verstärkt sich in den Industrieländern ständig. Gleichzeitig üben pädagogische Disziplinen zunehmenden Einfluß auf die Entwicklung des Bildungswesens aus.Die Frage, wie sich diese Disziplinen in Polen entwickelt und wie sie das Bildungssystem beeinflußt haben, erfordert eine umfassendere Übersicht, die es ermöglicht, Schlußfolgerungen darüber zu ziehen, wie die pädagogische Forschung am besten mit dem Bildungswesen harmonisiert werden kann. Eine solche übersicht versucht der vorliegende Artikel zu geben. Er behandelt die folgenden Themen: die Funktionen der pädagogischen Forschung; die Art der in Polen angestellten Untersuchungen; die Verbreitungsmöglichkeiten ihrer Ergebnisse; und die Organisation der Forschung in Polen. Abschließend werden einige der wichtigeren Schlußfolgerungen besprochen.

Résumé De nos jours il n'est plus nécessaire de convaincre les gens que l'éducation moderne ne peut fonctionner de façon satisfaisante sans l'aide de la recherche scientifique, et plus spécialement de la recherche pédagogique. Il est vrai que l'on voit encore paraître de nombreux ouvrages pédagogiques gonflés de vent comme le disait déjà Comenius il y a plus de trois siècles, et ces publications peuvent éventuellement connaître une popularité passagère. Mais le courant général selon lequel la pédagogie est une discipline en developpement basée sur la recherche est désormais irréversible et il prend sans cesse plus d'importance dans les pays développés. Concurrement, les disciplines pédagogiques exercent une influence croissante sur le développement de l'éducation.Comment ces disciplines se sont-elles développées en Pologne et comment y ontelles influencé le système de l'éducation, sont deux questions qui demandent une étude approfondie si l'on veut en tirer des conclusions permettant d'harmoniser plus efficacement le domaine de la recherche en éducation et celui de l'éducation. C'est là l'objet de cet article. L'auteur considère les fonctions de la recherche en éducation, les différentes sortes d'enquêtes éducationnelles menées en Pologne, les moyens de diffusion des résultats et l'organisation de la recherche dans ce pays. Il termine par une discussion des conclusions les plus importantes auxquelles les Polonais sont parvenus.

The ARCS Model of Motivational Design has been used myriad times to design motivational instructions that focus on attention, relevance, confidence and satisfaction in order to motivate students. The Instructional Materials Motivation Survey (IMMS) is a 36‐item situational measure of people's reactions to instructional materials in the light of the ARCS model. Although the IMMS has been used often, both as a pretest and a posttest tool serving as either a motivational needs assessment prior to instruction or a measure of people's reactions to instructional materials afterward, the IMMS so far has not been validated extensively, taking statistical and theoretical aspects of the survey into account. This paper describes such an extensive validation study, for which the IMMS was used in a self‐directed instructional setting aimed at working with technology (a cellular telephone). Results of structural equation modeling show that the IMMS can be reduced to 12 items. This Reduced Instructional Materials Motivation Survey IMMS (RIMMS) is preferred over the original IMMS. The parsimonious RIMMS measures the four constructs attention, relevance, confidence and satisfaction of the ARCS model well, and reflects its conditional nature.  相似文献

Binocular disparity provides one of the important depth cues within stereoscopic three-dimensional (3D) visualization technology. However, there is limited research on its effect on learning within a 3D augmented reality (AR) environment. This study evaluated the effect of binocular disparity on the acquisition of anatomical knowledge and perceived cognitive load in relation to visual-spatial abilities. In a double-center randomized controlled trial, first-year (bio)medical undergraduates studied lower extremity anatomy in an interactive 3D AR environment either with a stereoscopic 3D view (n = 32) or monoscopic 3D view (n = 34). Visual-spatial abilities were tested with a mental rotation test. Anatomical knowledge was assessed by a validated 30-item written test and 30-item specimen test. Cognitive load was measured by the NASA-TLX questionnaire. Students in the stereoscopic 3D and monoscopic 3D groups performed equally well in terms of percentage correct answers (written test: 47.9 ± 15.8 vs. 49.1 ± 18.3; P = 0.635; specimen test: 43.0 ± 17.9 vs. 46.3 ± 15.1; P = 0.429), and perceived cognitive load scores (6.2 ± 1.0 vs. 6.2 ± 1.3; P = 0.992). Regardless of intervention, visual-spatial abilities were positively associated with the specimen test scores (η2 = 0.13, P = 0.003), perceived representativeness of the anatomy test questions (P = 0.010) and subjective improvement in anatomy knowledge (P < 0.001). In conclusion, binocular disparity does not improve learning anatomy. Motion parallax should be considered as another important depth cue that contributes to depth perception during learning in a stereoscopic 3D AR environment.  相似文献
