Family background data and California Psychological Inventory (CPI) protocols were obtained from 1643 Greek students (825 males, 818 females), from 19 schools in upper, above average, below average, and lower socioeconomic districts of the City of Athens. Students were enrolled in Grades 8 and 9 (gymnasio) or 10 through 12 (likio). Background variables, individual CPI scales, and a combination of six CPI scales developed earlier to forecast high school academic achievement in the United States were related to the scholastic performance of the Greek students. For all 1643 students, the optimum linear combination of three family background variables correlated .29 with grades, whereas the previously defined CPI equation had a correlation of .38. Similar results were observed in subsamples defined by sex and school level. It was concluded that the CPI measures showed sufficient validity in this cross-cultural application to warrant further research at higher educational levels, and in special subgroups such as the intellectually gifted or mathematically precocious.  相似文献

The present study explored typically developing children’s understanding of, and attitudes towards, the inclusion of children with physical disabilities (PD) in mainstream settings. The 60 children who participated in the study attended sixth grade in two mainstream primary schools (30 in contact with a child with PD and 30 without such contact). They filled in a questionnaire to measure understanding of disabilities and one to explore attitudes towards inclusion. Analyses revealed that children in contact with a child with PD had a better understanding of the emotional and social problems associated with the presence of PD than the comparison group. Moreover, children in contact with a child with PD expressed more positive attitudes towards the inclusion of children with PD in relation to children without such contact. Results are discussed in terms of the importance of contact in the formation of more positive attitudes towards the inclusion of children with PD.  相似文献

The purpose of this study was to examine the influence of a carbohydrate-rich meal on post-prandial metabolic responses and skeletal muscle glycogen concentration. After an overnight fast, eight male recreational/club endurance runners ingested a carbohydrate (CHO) meal (2.5 g CHO?·?kg?1 body mass) and biopsies were obtained from the vastus lateralis muscle before and 3 h after the meal. Ingestion of the meal resulted in a 10.6?±?2.5% (P?<?0.05) increase in muscle glycogen concentration (pre-meal vs post-meal: 314.0?±?33.9 vs 347.3?±?31.3 mmol?·?kg?1 dry weight). Three hours after ingestion, mean serum insulin concentrations had not returned to pre-feeding values (0 min vs 180 min: 45?±?4 vs 143?±?21 pmol?·?l?1). On a separate occasion, six similar individuals ingested the meal or fasted for a further 3 h during which time expired air samples were collected to estimate the amount of carbohydrate oxidized over the 3 h post-prandial period. It was estimated that about 20% of the carbohydrate consumed was converted into muscle glycogen, and about 12 % was oxidized. We conclude that a meal providing 2.5 g CHO?·?kg?1 body mass can increase muscle glycogen stores 3 h after ingestion. However, an estimated 67% of the carbohydrate ingested was unaccounted for and this may have been stored as liver glycogen and/or still be in the gastrointestinal tract.  相似文献

Abstract

To determine the time course of performance responses after an acute bout of plyometric exercise combined with high and low intensity weight training, a 3-group (including a control group), repeated-measures design was employed. Changes in performance were monitored through jumping ability by measuring countermovement and squat jumping, and strength performance assessment through isometric and isokinetic testing of knee extensors (at two different velocities). Participants in both experimental groups performed a plyometric protocol consisting of 50 jumps over 50 cm hurdles and 50 drop jumps from a 50 cm plyometric box. Additionally, each group performed two basic weight exercises consisting of leg presses and leg extensions at 90–95% of maximum muscle strength for the high intensity group and 60% of maximum muscle strength for the low intensity group. The results of the study suggest that an acute bout of intense plyometric exercise combined with weight exercise induces time-dependent changes in performance, which are also dependent on the nature of exercise protocol and testing procedures. In conclusion, acute plyometric exercise with weight exercise may induce a substantial decline in jumping performance for as long as 72 hours but not in other forms of muscle strength.  相似文献

This article uses Google Scholar (GS) as a source of data to analyse Open Access (OA) levels across all countries and fields of research. All articles and reviews with a DOI and published in 2009 or 2014 and covered by the three main citation indexes in the Web of Science (2,269,022 documents) were selected for study. The links to freely available versions of these documents displayed in GS were collected. To differentiate between more reliable (sustainable and legal) forms of access and less reliable ones, the data extracted from GS was combined with information available in DOAJ, CrossRef, OpenDOAR, and ROAR. This allowed us to distinguish the percentage of documents in our sample that are made OA by the publisher (23.1%, including Gold, Hybrid, Delayed, and Bronze OA) from those available as Green OA (17.6%), and those available from other sources (40.6%, mainly due to ResearchGate). The data shows an overall free availability of 54.6%, with important differences at the country and subject category levels. The data extracted from GS yielded very similar results to those found by other studies that analysed similar samples of documents, but employed different methods to find evidence of OA, thus suggesting a relative consistency among methods.  相似文献

This article reviews some studies of individual demand for higher education undertaken during the 1970s. It argues that although lifetime earnings are positively related to educational qualifications, rates of return to education do not seem to matter much for either public or private educational decisions. Public educational decisions seem to be affected more by such factors as the inertia of the system, expected externalities of socio-political importance, which are not measurable and, therefore, are excluded from the rate of return calculations and some educational objectives, such as meeting social demand and for ensuring equal opportunities to all individuals, which public authorities adopt at any time period. On the other hand, pupils' educational plans for post-secondary education were found to be greatly influenced by their scholastic achievement, sex and socio-economic status. It was also found that the economic factor which clearly enters into their decisions function, is initial salary differentials. However, a high proportion of pupils do not possess this information. It is also argued that individual demand for post-secondary education could be estimated with a high degree of approximation on the basis of pupils' scholastic achievement at secondary school, sex and socio-economic status. The pupil's ability to finance his further studies, particularly the poor student and in the absence of grant or loan systems is of great importance.  相似文献

When we refer to scientific knowledge, we, implicitly or explicitly, refer to its three components, namely its conceptual framework, its methodological principles and its cultural aspects. The pendulum is a topic of science teaching and learning where all three of these aspects can be examined with the aim of gaining a holistic appreciation of the transformation of a natural phenomenon into a phenomenon of the physical sciences and how this can then be recontextualized into a topic of school science learning. The main objective of this study is to examine whether this richness of the pendulum as a topic of teaching is revealed in the school science textbooks in Greece and Cyprus, for both primary and secondary education. We will use an analytical mapping instrument in order to determine, whether the pendulum is introduced at some grade level and, if so, in what context. We will then use an interpretive instrument, which relies on taxonomy of science curricula into traditional, innovative and constructivist programs, in order to attach meaning to the analysis. Finally, we will formulate a series of proposals in relation to the educational value of the simple pendulum at the Greek and Cypriot gymnasium level.  相似文献

The role of empathy in the teaching profession has been vastly investigated in relation to its effect on students, but research on how teachers’ empathy affects their own well-being at work is limited. This study investigated empathy and instructional assignment-related stress factors of primary school teachers serving in general or special education; moreover, it investigated if empathy predicted instructional assignment-related stress. Data were collected from 190 primary school teachers using the Interpersonal Reactivity Index and the Inventory of Job-related Stress Factors. Teachers reported moderately high levels of perspective-taking and empathic concern and lower levels of fantasising and personal distress. Also, they reported moderate to low levels of stress regarding instructional assignment-related factors. General and special education teachers did not differ in their reported scores on empathy or stress-related factors. Finally, it was found that instructional assignment-related stress factors can be predicted by personal distress and fantasising; however, the core empathy skills (empathic concern and perspective taking) were not found to be strong predictors of the stress factors tested.  相似文献
