This study examined the impact of job satisfaction and organizational commitment on teachers’ organizational citizenship behavior (OCB) in a structural equation model. The study was employed to a group of teachers and their supervisors. The results indicated that job satisfaction and commitment to the school had an impact on OCBs of the teachers and organizational commitment mediated the relation between job satisfaction and OCB. 相似文献

In applying impact loads with multishocks to perform shock experiments for laser cladded cobalt-base and nickel-base alloy coats on the surface of mild carbon steel or austenitic stainless steel, it is found that, under an impact force that is 11%-43% of the static yield limit of the material, micro-plastic deformation is generated both in the coat and upper part of the base. Repeated trials will cause cumulated macro-plastic deformation. After a total of 250,000 impacts, relative deformation rates of 2.2% and 8.9% result in the coat and base, respectively. Moreover, there is a rigidification phenomenon both in the coat and upper part of the base. When the coat covers the entire base, under impact loads with multishocks, the final stress is less than that when the base is only partly covered, and the life is longer.There is intense deformative rigidification and material floating effect on the lower part of the edge of the covering coat. Meanwhile, cracks are likely to occur and spread in this part. 相似文献

Teachers’ engagement in professional learning is vital to the profession’s sustainability. Their professional learning is influenced by the demands of balancing work, family, and the strain of balancing the two. This challenge is addressed through the notion resilience, operationalized as career adaptability. In a sample of teachers (N = 193), the present research explored the relations between career adaptability, family-to-work conflict (time-based and strain-based), and engagement in professional learning. Structural equation modelling revealed that time-based conflict mediated the relation between career adaptability and strain-based conflict. Strain-based conflict, in turn, negatively predicted engagement with professional development studies. It is recommended that strategies for teachers’ professional learning are inclusive of contextual factors, such as family-to-work conflict, and focused on enhancing their career adaptability. 相似文献

Experiments of silt rock subjected to coupling loads were carried out on tailormade equipment. With a constant dynamic load, the behaviors of eight sets of siltite specimens were investigated with different axial static loads. The experimental results show that the modulus of the specimens under coupling loads increases at first and then decreases with the increase of axial static pressure. The failure model of the specimens also varies. Keeping the dynamic load constant, when the axial static pressure is low, the specimen breaks in two simply. With the increase of axial static pressure, the cone-shaped fragment appeares. When the axial static pressure reaches 90% of the static strength of rock, the specimen smashes into amount of small fragments. 相似文献

This paper argues that participants and locals should be seen as at the centre of all development, including international and health development work. Consequently, in contexts of health and wellbeing, patients should be seen as active participants, which also implies the need for the independence and freedom of all and the development of dialogical spaces in which all may negotiate what counts as a life worth living. ‘Impact’, on this view, should be seen from a lifeworld perspective of evaluating the effects of dynamic evolving practices where all are seen potentially as donors and beneficiaries within contexts of mutually negotiated reciprocal relationships. Data drawn from extensive fieldwork with local trauma surgeons, midwives and healthcare personnel in rural Cambodia provide the basis of new perceptions about processes of ‘passing on’ knowledge and expertise. The ideas presented have potential implications for normative understandings of the social organisation of healthcare in domestic and international settings. 相似文献

The importance of groupware tools in e-learning practice is increasing, because of their educational relevance and of the
importance of group abilities in today’s job activities. The paper addresses some critical issues of asynchronous collaborative
tools hosted in Web-learning platforms. A model to capture user quality perceptions for these tools is presented, and an investigation
conducted in three case studies where e-learning platforms were used to share and comment on written works is reported in
detail. Quantitative and qualitative data are used in a complementary way to capture the complexity of educational collaborative
activities. The impact of technologies on work organization, writing and peer-feedback activities is discussed. Users dedicated
more time to feedback activities than they would have in real-life contexts, and paid more attention to the style and content
of their writing. Communication was more focused and honest than in real life (even though more distant and at the risk of
misunderstanding), and its indirectness encouraged shy and impaired people. Usability problems emerged from platform design,
educators’ choices and server-side settings; Web-based systems seem to pose specific usability issues when users are required
a strong active role; compatibility issues highlight the need for a closer Web standard compliance.

This study sought to explore the impact factors and associated rankings of criminology and criminal justice journals that have been ranked in the top 20 over the past 10 years (1998–2007). The results from this study suggested a considerable degree of similarity in the rankings of criminology and criminal justice journals compared to other known methods insofar as the rankings of the top journals such as CRIM and JRCD. However, further analyses revealed a noticeable amount of stability and variability in the journals that make the top 20 list over time and stability and variability in the rankings of specific journals themselves over time. Study limitations and suggestions for future research ranking criminology and criminal justice journals are also discussed. 相似文献

Research Findings: Students experienced a mindfulness program designed to enhance their self-regulation in prekindergarten and kindergarten. At the end of the 1st year of the program, these students showed improvements in teacher-reported executive function skills, specifically related to working memory and planning and organizing, whereas students in a business as usual control group showed a decline in these areas. No difference between the groups’ receptive vocabulary was found in prekindergarten. At the end of kindergarten, the mindfulness group had higher vocabulary and reading scores than the business as usual group. Practice or Policy: These findings suggest that mindfulness practices may be a promising technique that teachers can use in early childhood settings to enhance preschoolers’ executive functioning, with academic benefits emerging in the kindergarten year. 相似文献

Although the impact of Alzheimer’s disease training programs directed to informal and formal caregivers has been extensively studied, programs for older adults who do not have the disease are relatively few. Moreover, increased knowledge increases fear of the disease, even though there is little empirical evidence to support this. This study investigated the impact of an Alzheimer’s disease training program for older persons on their knowledge and fear of the condition. Participants consisted of 110 older adults who voluntarily applied for a 16-hour course as part of the University of the Third Age. A questionnaire, consisting of two validated tools (Alzheimer’s Disease Knowledge Scale and the Fear of Alzheimer’s Disease Scale), was distributed pre- and posttraining to the participants. Sixty-six questionnaires (response rate = 60%) were collected at the start of the program and 46 at the end (response rate = 42%). Participants’ fear at pretraining was significantly related to their current knowledge of the disease. Training significantly improved knowledge of the disease, but the participants’ perceived fear did not change. The study indicated that an Alzheimer’s disease training program for older persons can increase their knowledge, but it does not necessarily increase their fear. Training programs aimed at raising awareness of Alzheimer’s disease should target more effectively this age cohort who may be concerned and are seeking learning opportunities to know more about the condition. 相似文献

The impact of English on the Chinese mainland from multidimensional perspectives： historical, educational and political is critically discussed. Historically, English education has witnessed its inception, ups and downs, and the present boom. The recent expansion of English education is functionally and economically oriented at both individual and social levels. At the core of the impact of English stand the policy-making decisions of the Chinese government which has always played a significant directive role. 相似文献

The German Physics Olympiad is an extracurricular science contest for students. Here, they have the opportunity to compete against other talented students, can do physics outside of school, and take a first step to more engagement in the domain. Yet, female students participate in the competition in fewer numbers and are disproportionally more likely to drop out of the contest earlier than the male students.
The present study hence explored the question to which extent the German Physics Olympiad provides a threatening environment for female contestants’ intentions of persisting in physics. A total of 298 participants (28% female) were surveyed with respect to stereotype and social identity threat, as well as gender identification and sense of belonging as predictors of success expectations for and value of choosing to study physics. Success expectations and value of choosing to study physics were used as a measure for career intentions within the expectancy-value model.
The results support the conclusion that the contest presents an equally supporting environment for female and male participants. We found no gender differences in success expectations for and value of studying physics. Sense of belonging and gender identification significantly predicted success expectations but not value of choosing to study physics. Female participants in the German Physics Olympiad were also neither affected by stereotype threat nor by social identity threat in their sense of belonging or gender identification.

This paper presents the findings of a small-scale qualitative research enquiry into some of the effects on the primary school art curriculum of the introduction of the National Literacy and Numeracy Strategies in 1988 and 1999. Five art curriculum co-ordinators and an additional part time specialist art teacher, drawn from five inner city primary schools in two London boroughs, were the subject of a semi-structured interview designed to elicit data on the broad changes in primary art education. Key external factors were the introduction of the Art National Curriculum in 1992, its subsequent development and its current condition during a period of ‘relaxation’ of the Orders, following the government's introduction of the Literacy and Numeracy Strategies. Little official attention has been given to other, perhaps unintended, outcomes of the latter strategy across the curriculum. This study gives an insight into the experience and perceptions of some of those carrying the responsibility for leadership of art in school in the primary phase. 相似文献

The purpose of this study was to evaluate whether the cross-language relations between the phonological awareness (PA) skills of preschool children learning more than one language are dependent upon their first- and second-language oral language skills. Four hundred sixty-six Spanish-speaking language minority children participated in this study. Results indicated that the relation between children’s first- and second-language PA skills varied as a function of their first- and second-language oral language skills. This effect was language specific such that only oral language skills in the same language as the PA outcome moderated the relations between children’s first- and second-language PA skills. This study helps extend findings from prior research on the cross-language transfer of PA. 相似文献

Stereotypes, prejudice, and discrimination against the elderly (ageism) may manifest themselves in children at an early age. However, the factors influencing this phenomenon are not well known. Using both explicit and open-ended questions, this study analyzed the influence of personal and familial parameters on the views of 1,151 seven- to sixteen-year-old Belgian children and adolescents on the elderly. Four factors were found to affect these views: gender (girls had slightly more positive views than boys), age (ageism was lowest in 10- to 12-year-old, reminiscent of other forms of stereotypes and cognitive developmental theories), grandparents’ health, and most importantly, quality of contact with grandparents (very good and good contacts correlated with more favorable feelings toward the elderly, especially in children with frequent contacts). 相似文献
