Despite decades of studies of human infants, a still open question concerns the role of visual experience in the development of the ability to perceive complete shapes over partial occlusion. Previous studies show that newborns fail to manifest this ability, either because they lack the visual experience required for perceptual completion or because they fail to detect the pattern of motion. To distinguish these possibilities, newborns' perception of a center-occluded object was tested, using stroboscopic motion. Infants (mean age of 72 hr) perceived the object as a connected unit, providing the first evidence that the newborn is capable of filling in gaps in the visible surface layout when the relevant visual information can be detected by his or her immature visual system. 相似文献

This article makes the case for clearer reporting of alternative provision. The main body of this paper consists of an analysis of available data on permanent exclusions and attendance at alternative provision. Findings show a greater number of young people attending alternative provision compared to those permanently excluded and concerning patterns of over representation among children in care and those with a special educational need or disability. This raises issues of children’s rights, particularly equality of educational experience and of fair access to the schooling system. It is argued that annual reporting on exclusions should be developed to include a section of in depth reporting on alternative provision. 相似文献

The recent surge in interest in progressive education ideas has often been accompanied by an increased advocacy for learning outdoors, with experiential and holistic learning approaches considered the most beneficial method for cultivating personal and social development and raising awareness of contemporary environmental concerns. However, theoretical and practical unease exists about how increased opportunities to learn outdoors can help young people to reflect on their experiences and make sound decisions. The paper reviews the contribution of John Dewey to debates about experiential education and the development of moral deliberation; as for Dewey there are strong connections between cognition, character and actions. This leads, in conclusion, to analysis of outdoor learning prospects and the extent to which these can benefit personal responsibility and social interaction, and provides learners with the capacity to make dependable voluntary decisions that display stable states of character. 相似文献

The angiogenesis-signalling pathway is a physiological response after mechanical loading to promote matrix remodelling and thereby maintain tissue homeostasis. Studies have shown increased expression of angiogenic molecules in response to loading and in ruptured ligaments. Recently, polymorphisms within the vascular endothelial growth factor A (VEGFA) and kinase insert-domain receptor (KDR) genes were associated with risk of anterior cruciate ligament (ACL) ruptures and Achilles tendinopathy in Caucasian study groups. A case-control genetic association study was conducted on 100 controls and 98 participants with surgically-diagnosed ACL ruptures; of which 51 participants reported non-contact mechanism of injury (NON). All participants were genotyped for five functional polymorphisms: VEGFA (rs699947, rs1570360, rs2010963) and KDR (rs2071559, rs1870377). Haplotypes were inferred. In the male participants, the KDR rs2071559 AG genotype was significantly over-represented (P = 0.048, OR: 1.90, 95% CI: 1.00–3.59) in the controls. Furthermore, the GG genotype was significantly under-represented in the male controls compared to the male ACL group (P = 0.018, OR: 2.77, 95% CI: 1.17–6.55) and the male NON subgroup (P = 0.013, OR: 3.26, 95% CI: 1.24–8.58). Haplotype analysis implicated the KDR gene in all participants and in male participants separately. Collectively, these results implicate the angiogenesis-signalling pathway as a potentially key biological pathway contributing to ACL injury susceptibility. 相似文献

In this study, the authors examine Major League Baseball free agency to identify whether certain factors beyond a player’s on-field performance contribute to contract premiums. These premiums are considered to be the difference between the compensation a player receives in free agency and the marginal revenue product (MRPt-1) in their contract year. Using 345 free agent transactions over a four-year period (2012–2015), the authors examine the relationships between potential free agent contract premiums and the attributes of a player’s previous team, as well as how contract premiums may be influenced by the level of interest from other teams and certain facets of the acquiring teams. Results suggest that free agents tend to receive compensation premiums when they played for a successful team during their contract year. Playing for a large-market team during their contract year also influenced contract premiums. In addition, free agents tended to realize compensations premiums when multiple teams were bidding for their services, the acquiring teams were in playoff contention the prior year, and the acquiring teams possessed relatively more financial resources. Findings shed additional light on how factors peripheral to a player’s on-field performance may influence the free agency market. Recommendations include that effective control mechanisms are necessary to ensure free agent compensation is commensurate with the value of the player. 相似文献

Children's ethnicity-status associations are often studied in societies where one ethnic group possesses status across multiple dimensions, such as political influence and wealth. This study examined children's (6–12 years) and adults' representations of more complex hierarchies in Indonesia (N = 341; 38% Native Indonesian, 33% Chinese Indonesian, and 27% other ethnicities; 55% female, 36% male; 2021–2022), a society where ethnic groups hold distinct forms of status (on average, Native Indonesians have political influence; Chinese Indonesians have wealth). By 6.5 years, children associated Native Indonesians with political influence and Chinese Indonesians with wealth. Intersectional analyses indicated that ethnicity-status associations were stronger for male than female targets. Children of all ethnicities preferred Chinese Indonesians and preferences were predicted by wealth judgments. 相似文献

Many forms of bias have been identified in higher education research, and in educational and social research in general. This article identifies a further form of bias, positivity bias, and places it in this broader context. Positivity bias is the tendency, in some forms of published higher education research, to only or chiefly report examples of initiatives or innovations that worked and received positive evaluations. Empirical evidence of positivity bias, in the form of an analysis of a sample of published articles from selected higher education journals, is presented and discussed. Suggestions as to the causes of positivity bias and how it might be handled are presented. 相似文献
