Truancy is known to: Hamper academic achievement, predict a range of school-related problems and cause early school leaving. Hence, the development and implementation of measures to tackle truancy are considered as important strategies to prevent early school leaving in Europe. Despite this, there is almost no comparative research which studies variation in truancy rates. This article relies on PISA 2012 data from 24 European countries to empirically answer two questions: (1) To what degree do truancy rates vary cross-nationally? and (2) Do these differences in truancy rates relate to characteristics of the educational system? We found that between-country truancy rates varied more than differences in early school leaving. Moreover, even after taking into account control variables such as economic development and youth unemployment rates, the ways in which educational systems select and group pupils are closely related to truancy rates.  相似文献

Do children construe leaders as individuals whose position of power entails primarily more responsibility or more entitlement, compared with nonleaders? To address this question, 5-year-old children (n = 128) heard a story involving a hierarchical dyad (a leader and a nonleader) and an egalitarian dyad (two nonleaders), and then assessed protagonists’ relative contributions to a collaborative endeavor (Experiments 1 and 2) or relative withdrawals from a common resource pool earned jointly (Experiment 3). Children expected a leader to contribute more toward a joint goal than its nonleader partner, and to withdraw an equal share (not more) from a common pool. Children thus gave evidence that they construed leaders as more responsible, rather than more entitled, relative to nonleaders.  相似文献

Adults’ attraction to rare objects has been variously attributed to fundamental biases related to resource availability, self-related needs, or beliefs about social and market forces. The current three studies investigated the scarcity bias in 11- and 14-month-old infants, and 3- to 6-year-old children (N = 129). With slight methodological modifications, participants had to choose between one of 10 same-kind-items (abundant resource), or the only one of a different kind (scarce resource). It was found that a robust preference for the scarce resource appeared only at age 5 years. Thus, although a scarcity bias is not present in infancy, it emerges prior to comprehension of market forces. Possible accounts of this developmental finding are discussed.  相似文献

This study sheds light on polycentric forms of organizing and corresponding performance implications. Organizations with a polycentric architecture supplement their internal hierarchical decision-making structures with egalitarian, local structures in order to encourage collaboration with legally independent stakeholders. We ground our study on the planning stage for four capital-intensive infrastructure development projects (megaprojects) in the UK. We first establish that megaproject planning is carried on by polycentric organizations. We show that in this form of organizing the promoter has decision-making authority over the high-order choices, but shares the authority over the local choices with groups of autonomous stakeholders. We also show how this organizational architecture addresses local disputes and pressures to relax performance targets. Our main contribution is a contingency model that proposes four conditions linking performance to polycentric organizing, whether or not: i) the institutional environment empowers an ‘umpire’ to referee disputes; and ii) the system leader can mobilize substantial slack resources to reconcile conflicting interests. We argue that the four conditions reveal very different classes of managerial problems, and draw implications for practice and policy including but not limited to megaprojects.  相似文献

The aim of this study was to examine the metabolic effect of a female soccer match in elite and sub-elite teams. Blood samples were taken (24 h before, immediately after and 18 h after official soccer matches) to determine haematological, electrolytic and hormonal variables, as well as the levels of cell damage and oxidative stress in 14 elite and 14 sub-elite players. Our results show increases in white blood cell count (P < 0.001) and the percentage of neutrophils (P < 0.001), and decreases in the percentage of lymphocytes (P < 0.05), eosinophils (P < 0.001), monocytes (P < 0.001) and basophils (P < 0.05) immediately post-match. Increases were also found in lactate dehydrogenase activity (P < 0.001), uric acid (P < 0.001), albumin (P < 0.001), total antioxidant status (P < 0.001) and free testosterone levels (P < 0.01). Creatine kinase activity significantly increased 18 h post-match (P < 0.01) and the concentrations of several ions, glucose and proteins were found to be altered immediately post-match. Overall, our results show that playing a soccer match exerts specific metabolic effects on female players, resulting in muscle damage, oxidative stress and biochemical and hormonal variations. On the basis of some interesting correlations, we also suggest that exercise-induced cell breakdown may enhance antioxidant capacity of the soccer players.  相似文献

We explore how risk management and design flexibility interplay in major (infrastructure) projects, using the £4.2bn Terminal 5 project to expand London's Heathrow airport. By juxtaposing these two conceptual frames, we unearth the conditions under which they can be complements for managing the tension between efficiency and effectiveness central to these projects. Building design flexibility - through modular or safeguarded integral architectures - increases adaptability to accommodate evolving requirements which is necessary to attain effectiveness. Efficiency, in turn, demands risk management to deliver the project ‘on time, within budget’. We explain variation in the interplay between the two approaches, highlighting the moderating role of the developer's relationship with the customer. Strong co-operation, particularly in a stable environment, encourages investments in design flexibility. Risk management practices prevail when co-operation breaks down. Another insight is that co-location and continuity of key project staff are themselves inadequate conditions to sustain co-operation.  相似文献

This article examines the new-century business relevance of information literacy and why it is important for undergraduate business students. It then validates the relevance and value of the elements that make up the concept of information literacy with current business professionals (recruiters and employers). Business professionals were surveyed to reveal their (1) familiarity with the term information literacy, (2) feelings about the relevancy and value of information literacy in the business workplace, (3) perceived competency in information literacy of undergraduate business school graduates, (4) validation of cognitive difficulty elements of information literacy, and (5) reactions to other terms/phrases that more closely align with the concepts of information literacy in the business workplace. Although these business professionals were in general not familiar with the term, once they were informed of its components, they recognized and valued its processes.  相似文献

The main topic of this article is to consider the role of the State in providing higher education in Portugal, paying attention to the fact that the privatisation of higher education has been in place since the eighties (Amaral 1999) and also that it is difficult for students and their families to find the monetary resources needed for attendance at university (Cabrito 1999). The discussion focuses on the funding of higher education in a quasi-market situation (Le Grand et al. 1993), as Portugal hasn't escaped the universal trend towards privatisation of education (Whitty et al. 1998). In the last decade, the relationship between State, universities and students has been changing rapidly (Acherman et al. 1989; Barr et al. 1993; Williams 1990; Henkel et al. 1999), and some arguments are presented that equity in access to higher education must be guaranteed (Mora 1997; UNESCO 1998; Williams 1992). In this connection, the need is argued for free attendance on higher education and State subsidies to students to cover the costs of education. Firstly, the economic and social condition of university students is presented. Using data from two periods, one academic year from the 60s and one from the 90s, the increase in the degree of equity that the university system had known in recent decades can be verified. According to the analysis, the Portuguese population in general is better represented in the university student body nowadays, than in the 60s. Therefore, it is possible to discuss the maintenance of a low degree of equity in the Portuguese university system. For this, the economic and social condition of university students is compared with – that of the Portuguese population in the 90s. Secondly, the expectations of the students of higher education are presented, in order to understand the value attached by them to a university degree, which explains the social demand for education. Finally, the costs of higher education, both private and public, are evaluated. From this evaluation, it is possible to conclude that the principal source of funding of higher education costs is the student and his/her family and to discuss the need for a more interventionist State in higher education financing. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

Blended learning has risen in popularity in the last two decades as it has been shown to be an effective approach for accommodating an increasingly diverse student population in higher education and enriching the learning environment by incorporating online teaching resources. Blending significant elements of the learning environment such as face‐to‐face, online and self‐paced learning leads to better student experiences and outcomes and more efficient teaching and course management practices if combined appropriately. Hence, an appropriate systematic and dynamic approach of blended learning design is crucial for a positive outcome, starting with planning for integrating blended elements into a course and creating blended activities and implementing them. Evaluating their effectiveness and knowing in which environments they work better and improving the blended activities designed from both the student’s and instructor’s perspective are critical for the next delivery of the course. This article aims to increase awareness of higher education educators about how traditional face‐to‐face learning can be transformed into blended courses so as to develop student engagement with both in‐class and online approaches, whilst being time effective for the instructor.  相似文献
