Research Findings: Data from a national sample of Portuguese preschool centers were used to examine the relationship between age of start and number of hours in child care and levels of externalizing and prosocial behaviors with peers. Participants were both parents and teachers of 543 children (mean age = 4.5 years, 50.6% girls). Children started child care between 3 and 64 months and were attending child care 1–9 hr per day. The child care centers’ classrooms had adult–child ratios between 5 and 8.7 and group sizes between 15 and 26 children. Externalizing and prosocial behavior with peers was assessed with the Social Competence and Behavior Evaluation Scale–Short Form completed by the 3 adult informants. Control variables included family sociodemographics and education level, maternal parenting style assessed with the Parenting Styles and Dimensions Questionnaire, and maternal stress assessed with the Parenting Experiences questionnaire. Practice or Policy: Both the number of hours per week in child care and an earlier start of center-based child care had modest but significant associations with dimensional scores from teachers’ reports of externalizing behavior but not with mothers’ or fathers’ reports, suggesting that externalizing behavior with peers could be regarded as context specific to peer relationships in group child care. There was no evidence that the quantity of exposure to child care per se could be a substantial risk factor for severe levels of externalizing behavior. Prosocial behavior with peers was not significantly associated with the number of hours in child care or with the age of entry into group child care. 相似文献

The growing competitiveness of modern sport means that children, from very early ages, are increasingly submitted to intensive training programmes. These programmes are problematic for young athletes not only because their developing bodies are particularly susceptible to different kinds of injuries, but because athletes are also particularly vulnerable to experiences of different kinds of abuses. Using data collected through semi-structured interviews this study examines the various kinds of abuse that former Portuguese female gymnasts underwent during their sporting careers. Interviewees were asked to reflect on their past experiences and discuss aspects of the gymnastics subculture. Weight control, training/competing with injuries and corporal punishment emerged as key themes. The study therefore shows that the physical and psychological abuse of young athletes occurs even beyond the confines of elite professional sport, and thus that a broader spectrum of athletes learn to consider these forms of exploitation and abuse as normal. 相似文献

This paper reports on a study conducted as part of an action-research project—INTEGRA I&E—aiming to promote the research and teaching (R&T) nexus at the School of Social Sciences and Humanities of a Research University in Lisbon, Portugal (Instituto Universitário de Lisboa, ISCTE-IUL). This study set out to investigate a multi-informant perspective of the academics’ rhetoric (conceptions, perception of barriers/facilitators and consequences) concerning the nexus, which can be considered at different levels of the curricular and organizational structure. Focus groups were conducted with 26 professors and 8 researchers from six different disciplinary areas and, afterwards, recorded and transcribed. A content analysis was used to categorize and quantify participants’ responses. Four themes emerged: practices linking R&T, barriers, facilitators and consequences of the nexus. Different levels of analysis were identified for each theme, namely, the level of ISCTE-IUL, Research Centers, Departments, Courses and Classes. Some disciplinary differences were also encountered. This study contributes with a multi-informant and multi-level perspective of academics’ conceptions of the R&T nexus in a Portuguese research-oriented university. 相似文献

The education system in Portugal is in the midst of a period of intensive reform. This paper describes the findings of a qualitative case study focusing on the views and attitudes of teachers and students participating in a pilot curriculum development programme stressing active methodologies and group work, conducted by the Ministry of Education. In particular it discusses their views and attitudes about mathematics, mathematics teaching and curriculum innovation. The teachers were found to struggle with a contradiction: whilst they approved the new orientations, which were seen as adequate and innovative, they complained strongly about the design and implementation of the programme — Students had a generally positive attitude towards mathematics, although there were differences among them. The 7th graders were satisfied with their mathematics classes and with the new curriculum. The 10th graders did not consider the changes as significant in themselves, but expressed concern for their academic progress. 相似文献

Two experiments (n = 10) were conducted to determine the effects of roller massager (RM) on ankle plantar flexor muscle recovery after exercise-induced muscle damage (EIMD). Experiment 1 examined both functional [i.e., ankle plantar flexion maximal isometric contraction and submaximal (30%) sustained force; ankle dorsiflexion maximal range of motion and resistance to stretch; and medial gastrocnemius pain pressure threshold] and morphological [cross-sectional area, thickness, fascicle length, and fascicle angle] variables, before and immediately, 1, 24, 48, and 72 h after an EIMD stimulus. Experiment 2 examined medial gastrocnemius deoxyhaemoglobin concentration kinetics before and 48 h after EIMD. Participants performed both experiments twice: with (RM) and without (no-roller massager; NRM) the application of a RM (6 × 45 s; 20-s rest between sets). RM intervention did not alter the functional impairment after EIMD, as well as the medial gastrocnemius morphology and oxygenation kinetics (P > 0.05). Although, an acute increase of ipsilateral (RM = + 19%, NRM = ?5%, P = 0.032) and a strong tendency for contralateral (P = 0.095) medial gastrocnemius pain pressure threshold were observed. The present results suggest that a RM has no effect on plantar flexors performance, morphology, and oxygenation recovery after EIMD, except for muscle pain pressure threshold (i.e., a soreness). 相似文献

The aim of this study was: (i) to group basketball players into similar clusters based on a combination of anthropometric characteristics and playing experience; and (ii) explore the distribution of players (included starters and non-starters) from different levels of teams within the obtained clusters. The game-related statistics from 699 regular season balanced games were analyzed using a two-step cluster model and a discriminant analysis. The clustering process allowed identifying five different player profiles: Top height and weight (HW) with low experience, TopHW-LowE; Middle HW with middle experience, MiddleHW-MiddleE; Middle HW with top experience, MiddleHW-TopE; Low HW with low experience, LowHW-LowE; Low HW with middle experience, LowHW-MiddleE. Discriminant analysis showed that TopHW-LowE group was highlighted by two-point field goals made and missed, offensive and defensive rebounds, blocks, and personal fouls; whereas the LowHW-LowE group made fewest passes and touches. The players from weaker teams were mostly distributed in LowHW-LowE group, whereas players from stronger teams were mainly grouped in LowHW-MiddleE group; and players that participated in the finals were allocated in the MiddleHW-MiddleE group. These results provide alternative references for basketball staff concerning the process of evaluating performance. 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
