Summary This paper reports on a questionnaire survey of teachers’ attitudes towards 16 selected undesirable behaviours carried out in all of the 79 state primary schools in Malta and Gozo. The responses of the 844 participants showed that stealing, cruelty/bullying and rudeness/impertinence are perceived as the three most serious behaviours in pupils. Significant boy/girl differences in the seriousness of behaviour were observed in 14 of the behaviours as rated by the total teacher sample, in 9 of the behaviours as rated by male teachers, and in 14 of the behaviours as rated by female teachers. The greatest boy/girl differences in the ratings of the behaviours was that for untidy in personal appearance as perceived by male teachers. Teacher‐sex was also found to be a significant moderator of the teachers’ attitude towards seven of the behaviours.  相似文献

A questionnaire survey of 710 Maltese primary schoolteachers revealed that the level of teacher stress, job satisfaction and career commitment was constituted differently in some of the teacher demographic subgroups. A principal components analysis of the stress ratings of 20 items covering various aspects of the teacher's work environment yielded four factors described in terms of ‘pupil misbehaviour’, ‘time/ resource difficulties’, ‘professional recognition needs’ and ‘poor relationships’. Teacher sex and ability‐group taught interacted significantly with the stress factors. Results also showed that teachers who reported greater stress were less satisfied with their job and less committed to choose a teaching career were they to start life over again. Moreover, the association between the general measure of job stress and the stress due to each of the four stress factors was strongest for ‘pupil misbehaviour’ and ‘time/resource difficulties’. Of the four factors, ‘professional recognition needs’ had the strongest inverse relationship with job satisfaction and career commitment.  相似文献

The purpose is to document the ongoing development of two schools in becoming professional learning communities and the effects of meaningful collaboration on teacher learning. The question that guides this research is: How does a school become a sustainable professional learning community? The theoretical framework is based on the work of Senge, Hord, Fullan, Hargreaves and Fink, and Stoll, McMahon and Thomas and includes the areas of professional learning community, change and sustainability. Finally, the study addresses the relationship between professional learning community and school culture. The methodology involves a qualitative case study approach designed to gain information regarding two emerging schools in their journeys toward developing learning community cultures. Findings reveal the stories of each school as they evolved as PLCs and the similarities and differences that emerged. Knowing that sustaining the culture of a PLC is complex, and not to be achieved without determination and growth, we look ahead at challenges to be addressed and further research to be conducted. Finally, we offer some concluding statements and attempt to relate findings to the literature on PLCs. The intent is to identify some of the intricacies in building cultures of learning for adults and students. As we have learned through these two stories, many things happen simultaneously, to greater or lesser degrees, at varying points in time over a period of years that seem to influence the development of a PLC. Such development seems so complex that to be able to describe discrete steps or stages is unlikely. Still we are beginning to see that some categories of activities and issues must be developed before others can emerge.  相似文献

The article examines a number of links between the metaphorical uses of the concept of metamorphosis in literature and the various changes of the meaning of the concept that took place at the beginning of the modern scientific age between the 17th and 19th centuries, a period during which the notion of metamorphosis resurfaced in conflict with evolutionist thinking. We present the extent to which the concept of animal metamorphosis, the object of multiple redefinitions over the course of this historical period, became the vector of a very strong metaphorical meaning, which emerged in the literature of the period and survives to this day in certain children’s storybooks belonging to what we term the genre of “realistic fiction”. We intend, from a pedagogical standpoint, to identify which specific attributes of these metaphors exist in those storybooks, and to gauge the extent to which those attributes contradict the scientific characteristics and fictional representations of the concept of metamorphosis.  相似文献

Know-how is a critical element of franchising, and its transfer is a key issue for franchisors and their staff. The aim of this paper was to analyse franchisees’ perceptions about know-how transfer in franchise networks. Findings of our qualitative empirical study show that franchisees seem to value the mechanisms used in their network, which include formalised processes (the operations manual, online tools), training (initial and ongoing) and social mechanisms (discovery sessions, meetings and committees). Only the effectiveness of on-field consultants is questioned, which leads to important managerial implications. At the theoretical level, the paper contributes to our understanding of franchise operations by providing a franchisee-centred model of how knowledge is created and disseminated in the networks.  相似文献

This paper investigates the causal effect of foreign acquisitions on the research and development (R&D) activities of domestic target firms over the period 1994–2004. Using accounting data on French innovative manufacturing firms, we implement appropriate difference-in-difference estimation techniques associated with a matching propensity score procedure. We find that the acquisitions of French firms by foreign companies boost R&D spending. There is a simultaneous rise in the external and in-house R&D expenditures of French acquired firms. R&D is more contracted out to local research providers, in particular to local public laboratories and universities. The increase in internal R&D spending benefits to development, but also basic and applied research. Finally, the growth of the R&D budget is not only financed by internal resources but also receives financing from external partners, especially parent companies. Thus, our results call into question the idea that foreign takeovers hamper the R&D development of target firms and are detrimental to the national innovation system of the host country. First, acquisitions appear to bring efficiency gains enough to counterbalance the various costs of integration and market power effects, pushing firms to invest more in R&D. Acquisitions do not seem to incite managers to take shorter term and more financial driven decisions at the expense of R&D. Second, when motivated by technology sourcing and overseas R&D development, acquisitions might be used to access the specific know-how of target firms and to tap into the knowledge of the national innovation system. Then, purchaser firms could be more likely to develop the innovative capability of target firms and to strengthen their linkages with local partners than to reduce them and relocate R&D abroad.  相似文献

Parallel computation approaches for flexible multibody dynamics simulations   总被引:1,自引:0,他引:1  
Finite element based formulations for flexible multibody systems are becoming increasingly popular and as the complexity of the configurations to be treated increases, so does the computational cost. It seems natural to investigate the applicability of parallel processing to this type of problems; domain decomposition techniques have been used extensively for this purpose. In this approach, the computational domain is divided into non-overlapping sub-domains, and the continuity of the displacement field across sub-domain boundaries is enforced via the Lagrange multiplier technique. In the finite element literature, this approach is presented as a mathematical algorithm that enables parallel processing. In this paper, the divided system is viewed as a flexible multibody system, and the sub-domains are connected by kinematic constraints. Consequently, all the techniques applicable to the enforcement of constraints in multibody systems become applicable to the present problem. In particular, it is shown that a combination of the localized Lagrange multiplier technique with the augmented Lagrange formulation leads to interesting solution strategies.  相似文献

Online citizen science allows us to bridge the gap between researchers and nonresearchers and to improve the scientific literacy of nonresearchers. The aims of the present study were (a) to determine whether a 5‐week randomized control trial conducted by teachers in their classroom could improve 7‐ to 12‐year‐old children's inhibitory control (IC) and (b) to provide proof of concept that online scientific research projects can provide meaningful results in the context of education. As expected, children in the IC training group improved their IC efficiency to a greater extent than children in the control training group. We provide the first evidence that such online scientific research projects can be effective in improving children's IC abilities and bridge the gap between the lab and the classroom.  相似文献

Despite the critical role of regulations on competition and innovation, little is known about firm responses and related effects on performance under regulatory contingencies that are permissive or restrictive. By longitudinally investigating hybrid cars competing in the Le Mans Prototype racing (LMP1), we counter-intuitively suggest that permissive regulations increase technological uncertainty and thus decrease the firms’ likelihood of shifting their technological trajectory, while restrictive regulations lead to the opposite outcome. Further, we suggest that permissive regulations favour firms that innovate their products by sequentially upgrading core and peripheral subsystems, while restrictive regulations (in the long term) favour firms upgrading them simultaneously. Implications for theory and practice are discussed.  相似文献
