Zoo educators are important communicators of the targets in education for sustainable development and therefore carry great responsibility for global environmental change. However, German zoo educators form a heterogeneous group, many of them working in non-permanent job positions and facing multiple challenges at work. Applying the job demands-resources model, our study aims at revealing factors influencing zoo educators’ job strain. Our data from eight in-depth interviews with German zoo educators confirm that they perceive common factors known from other studies, such as demands (e.g. workload) and resources (e.g. supervisory support). Besides this, job-specific factors were identified (e.g. working with humans and animals). The demands zoo educators mentioned could be classified either as job hindrances (e.g. lack of equipment) or job challenges (e.g. learning). Future studies should quantify these results to facilitate the development of appropriate measures to reduce educators’ job strain, thus enhancing their performance. 相似文献

The onset of directed reaching demarks the emergence of a qualitatively new skill. In this study we asked how intentional reaching arises from infants' ongoing, intrinsic movement dynamics, and how first reaches become successively adapted to the task. We observed 4 infants weekly in a standard reaching task and identified the week of first arm-extended reach, and the 2 weeks before and after onset. The infants first reached at ages ranging from 12 to 22 weeks, and they used different strategies to get the toy. 2 infants, whose spontaneous movements were large and vigorous, damped down their fast, forceful movements. The 2 quieter infants generated faster and more energetic movements to lift their arms. The infants modulated reaches in task-appropriate ways in the weeks following onset. Reaching emerges when infants can intentionally adjust the force and compliance of the arm, often using muscle coactivation. These results suggest that the infant central nervous system does not contain programs that detail hand trajectory, joint coordination, and muscle activation patterns. Rather, these patterns are the consequences of the natural dynamics of the system and the active exploration of the match between those dynamics and the task. 相似文献

In order to initiate more research on the role of reading motivation during the initial stages of learning to comprehend texts, we developed the Reading Motivation Questionnaire for Elementary Students (RMQ‐E). The sample comprised 1497 elementary students in Grades 1–3. By means of exploratory and confirmatory factor analyses, three factors were determined: Curiosity, involvement and competition. The three‐factor structure of the RMQ‐E was found to be invariant across grade levels (scalar invariance) and across female and male students (strict invariance). As was anticipated, students in higher grades and male students were lower in curiosity and involvement than students in lower grades and female students. Whereas competitive reading motivation did not differ across grade levels, it was higher for boys than for girls. Moreover, the contributions of involvement and competition to reading amount and reading competence were in accordance with the hypotheses. The predictive validity of curiosity, however, was not confirmed. 相似文献

ABSTRACT— In this article, we discuss school schedules and their implications in the context of chronobiological contemporary knowledge, arguing for the need to reconsider time planning in the school setting. We present anecdotal observations regarding chronobiological challenges imposed by the school system throughout different ages and discuss the effects of these schedules in terms of sleepiness and its deleterious consequences on learning, memory, and attention. Different settings (including urban vs. rural habitats) influence timing, which also depends on self-selected sleep schedules. Finally, we criticize the traditional view of a necessary strict stability of sleep–wake habits. 相似文献

Background: Open Access (OA) to scientific information is an important step forward in communication patterns, yet we still need to reinforce OA principles to promote a cultural change of traditional publishing practices. The advantages of free access to scientific information are even more evident in public health where knowledge is directly associated with human wellbeing. Objectives: An OA ‘consolidation’ initiative in public health is presented to show how the involvement of people and institutions is fundamental to create awareness on OA and promote a cultural change. This initiative is developed within the project NEtwork of COllaboration Between Europe and Latin American Caribbean countries (NECOBELAC), financed by the European Commission. Methods: Three actions are envisaged: Capacity building through a flexible and sustainable training programme on scientific writing and OA publishing; creation of training tools based on semantic web technologies; development of a network of supporting institutions. Results: In 2010–2011, 23 training initiatives were performed involving 856 participants from 15 countries; topic maps on scientific publication and OA were produced; 195 institutions are included in the network. Conclusions: Cultural change in scientific dissemination practices is a long process requiring a flexible approach and strong commitment by all stakeholders. 相似文献

Several studies on children and adults with and without linguistic impairment have reported differences between verb and noun processing. The present study assessed whether noun and verb bases affect differently children’s reading of derived words. Thirty-six Italian good readers and 18 poor readers, all 4th or 5th graders, were asked to read aloud nouns derived from either a noun base (e.g., artista, artist) or a verb base (e.g., punizione, punishment). Word and base frequency affected latencies only for deverbal nouns, while an effect of word length emerged for denominal nouns and an inhibitory effect of suffix length was found for both types of stimuli. A high base frequency and a high whole-word frequency both led to higher levels of accuracy. Verb bases led to higher error rates than noun bases. Poor readers, although slower and less accurate than good readers, showed a pattern of results similar to that of typically developing readers. Data confirm that in 4th and 5th graders morphological decomposition may affect reading aloud of long complex words, and that the grammatical class of the base can modulate this effect. 相似文献

School success is closely linked to intelligence but also to non-cognitive factors such as achievement motivation. The present study examines which non-cognitive factors predict secondary school grades and looks at reasons why female students tend to outperform their male counterparts. A sample of 554 German freshman students provided measures of general intelligence, achievement motivation, science course choice, self-efficacy, self-perceived academic achievement, and test anxiety. Results show that achievement motivation, self-perceived academic achievement, and sex significantly contribute to the final secondary school success above intelligence. Females’ advantage in final secondary school grades becomes even larger after controlling for general intelligence. This advantage can be explained by females’ higher achievement motivation. Showing more compensatory effort as well as self-control and taking more pride in their own productivity helps females to outperform their male counterparts at secondary school. 相似文献
