Adults create and update predictions about what speakers will say next. This study asks whether prediction can drive language acquisition, by testing whether 3- to 4-year-old children (n = 45) adapt to recent information when learning novel words. The study used a syntactic context which can precede both nouns and verbs to manipulate children's predictions about what syntactic category will follow. Children for whom the syntactic context predicted verbs were more likely to infer that a novel word appearing in this context referred to an action, than children for whom it predicted nouns. This suggests that children make rapid changes to their predictions, and use this information to learn novel information, supporting the role of prediction in language acquisition. 相似文献

The interaction of multiple influences on the path to sport success is not yet fully understood by sport scientists. In this study, we examined variation in body size, functional capacities and motivation for achievement, competitiveness and deliberate practice of youth basketball players associated with differences in biological maturity status, chronological age and years of training experience. Reflecting the importance of interactive effects, we examined the relationships between the psychological variables and functional capacities. Fifty-eight male basketball players aged 9.5 to 15.5 years were considered. Variables included chronological age, estimated age at peak height velocity, stature, body mass and sitting height by anthropometry; the Work and Family Orientation and Deliberate Practice Motivation Questionnaires were also used. Finally, the Line Drill test and Yo-Yo Intermittent Recovery level 1 (Yo-Yo IR1) tests were used as functional capacities indicators for basketball. Variance components models derived from series of multilevel linear regression models revealed a substantial variation by maturity status for body size, functional capacities indicators, mastery and will to excel. The influence of estimated maturity status on mastery and will to excel was independent of age and years of experience. In contrast, no relationships were observed between psychological variables and functional capacities indicators. We conclude that growth-related changes are relevant to understanding players´ motivations for achievement, competitiveness and deliberate practice. This should be of interest to those involved in the selection and development of youth basketball players. 相似文献

The present study compared the energy expenditure (EE) during and after two water aerobics protocols, high-intensity interval training (HIIT) and moderate continuous training (CONT). A crossover randomized design was employed comprising 11 healthy young women. HIIT consisted of eight 20s bouts at 130% of the cadence associated with the maximal oxygen consumption (measured in the aquatic environment) with 10s passive rest. CONT corresponded to 30 min at a heart rate equivalent to 90–95% of the second ventilatory threshold. EE was measured during and 30 min before and after the protocols and excess post-exercise oxygen consumption (EPOC) was calculated. Total EE during session was higher in CONT (227.62 ± 31.69 kcal) compared to HIIT (39.91 ± 4.24 kcal), while EE per minute was greater in HIIT (9.98 ± 1.06 kcal) than in CONT (7.58 ± 1.07 kcal). Post-exercise EE (64.48 ± 3.50 vs. 63.65 ± 10.39 kcal) and EPOC (22.53 ± 4.98 vs.22.10 ± 8.00 kcal) were not different between HIIT and CONT, respectively. Additionally, oxygen uptake had already returned to baseline fifteen minutes post-exercise. These suggest that a water aerobics CONT session results in post-exercise EE and EPOC comparable to HIIT despite the latter supramaximal nature. Still, CONT results in higher total EE. 相似文献

The present study aimed to determine the effects of physical training performed by parents on mice offspring adiposity. Male and female parents underwent an aerobic training protocol for 7 weeks. The trained and sedentary parents were allowed to mate and the resultant offspring divided in: S (Offspring from Sedentary Parents), T (Offspring from Trained Parents), ST (Offspring from Sedentary Father and Trained Mother) and TS (Offspring from Trained Father and Sedentary Mother). After weaning, offspring was euthanized, blood collected and samples of mesenteric and inguinal fat pads used to isolate adipocytes for morphologic and histological analyses. Lee index, mesenteric fat pad, sum of visceral fat and total fat weight of female T was reduced in comparison to the other groups (p < 0.05). Periepididymal and sum of visceral fat in male T group was also reduced when compared to the other groups (p < 0.05). The diameter of mesenteric and inguinal adipocytes of T group was smaller compared to all groups comparisons for both sexes (p < 0.05). In summary, exercise training performed by parents reduced visceral offspring adiposity, the diameter of subcutaneous adipocytes and improved metabolic parameters associated to metabolic syndrome. 相似文献

Changing Patterns in the Middle Management of Higher Education Institutions: The Case of Portugal 总被引：1，自引：0，他引：1
Abstact Much of the writing on higher education in recent years has tended to assume that the new management push in higher education
is both universal and irreversible. This paper, however, presents evidence from Portugal to challenge that assumption. While
elements of the new managerialism are clearly evident in the perceptions and attitudes of academics in charge of the basic
academic units (departments/schools and faculties) in the country’s universities and polytechnics, academic management remains
faced with a complex, contradictory and conflicting set of demands and expectations which is likely to take a considerable
time to resolve. 相似文献

During the past three decades, higher education institutions have been changing, moving away from the traditional bureaucratic archetype towards a more managerialist one. Empirical research already demonstrated that organisations tend to be in a hybrid area of archetypal change. Considering the specific case of a government-imposed reform in Portugal, and using a case study approach of six public universities, this study aims to explore archetypal hybridism through the lens of two main dimensions: systems and structures and interpretive scheme. The theoretical background lies on academic literature on organisational change in higher education and specifically on archetype theory. The findings drawn from document analysis and interviews outline the main characteristics of the hybrid archetype that we chose to name efficient-collegiality. 相似文献

A case study on project led education in engineering: students' and teachers' perceptions 总被引：1，自引：1，他引：1

This paper explores the extent to which students and teachers are able to acknowledge the strengths and weaknesses of a shift in the approach to teaching and learning from a traditional, teacher-centred perspective towards project- and learner-centred education. It reports on a case study aimed at exploring students' and teachers' perceptions of a project-led education course carried out at an engineering course at a Portuguese university. Data were collected through questionnaires, letters and interviews. Findings suggest, in spite of some negative experiences and final results for some of the students, a clear recognition of the benefits of a project-based approach to both the teaching staff as well as the students. Both are able to identify interdisciplinarity, high student motivation and the acquisition of soft skills as key features of project-led education. 相似文献
