AbstractDespite the frequently reported association of characteristics of assessment policies with academic performance, the mechanisms through which these policies affect performance are largely unknown. Therefore, the current research investigated performance, motivation and self-regulation for two groups of students following the same statistics course, but under two assessment policies: education and child studies (ECS) students studied under an assessment policy with relatively higher stakes, a higher performance standard and a lower resit standard, compared with Psychology students. Results show similar initial performance, but more use of resits and higher final performance (post-resit) under the ECS policy compared with the psychology policy. In terms of motivation and self-regulation, under the ECS policy significantly higher minimum grade goals, performance self-efficacy, task value, time and study environment management, and test anxiety were observed, but there were no significant differences in aimed grade goals, academic self-efficacy and effort regulation. The relations of motivational and self-regulatory factors with academic performance were similar between both assessment policies. Thus, educators should be keenly aware of how characteristics of assessment policies are related to students’ motivation, self-regulation and academic performance. 相似文献

This study was developed to identify and describe new trends and gender differences in the use of computers and the Internet
in South Korea. In this mixed-method study, both quantitative and qualitative techniques were used. Results indicated that
both males and females used computers generally for four purposes: social networking, personal knowledge, formal learning,
and entertainment. The study also found differences in preference between the sexes: Males liked playing multi-user online
games, especially in internet cafés with friends, while females enjoyed social networking websites more. Although the patterns
of computer use between males and females were ostensibly different, all participants used computers for fun and socializing.
Therefore, more emphasis should be placed on understanding various uses and the implications of emerging differences. Also,
consideration should be given to building learning environments that appeal to the computer preferences for both genders. 相似文献

This study examined the associations among maternal depression, mothers’ emotional and material investment in their child, and children's cognitive functioning. Middle-class Chilean mothers and children (N = 875; 52% males) were studied when children were 1, 5, 10, and 16 years (1991–2007). Results indicated that highly depressed mothers provided less emotional and material support to their child across all ages, which related to children's lower IQ. Children with lower mental abilities at age 1 received less learning-material support at age 5, which led to mothers’ higher depression at child age 10. Mothers’ low support was more strongly linked to maternal depression as children got older. Findings elucidate the dynamic and enduring effects of depression on mothers’ parenting and children's development. 相似文献

Introduction
Sparse data are available about the effect of therapy methods on antibody levels in patients with liver failure. The aim of this study was to determine serum immunoglobulin concentrations in patients with chronic hepatic failure (CHF), acute- (ALF), or acute-on-chronic liver failure (ACLF) and to evaluate the impact of MARS treatment or liver transplantation (LT) on antibody levels.Materials and methods
We followed ten patients with ALF, twelve with ACLF and 18 with CHF. Eight patients with ALF and seven with ACLF underwent MARS therapy, whereas the rest received LT. 13 healthy volunteers served as controls. Serum antibody concentrations were measured using ELISA-technique.Results
Median serum levels of IgA, IgG and IgM were significantly increased in patients with CHF compared to ALF or controls (P < 0.02, P < 0.01, and P < 0.01). IgM and IgG concentrations were also significantly elevated in patients with CHF compared to ACLF (IgM, 3.7 vs. 1 g/L, P < 0.001; IgG, 8.7 vs. 3.1 g/L, P = 0.004). Immediately after LT a significant decrease of IgA (6.9 vs. 3.1 g/L, P = 0.004), IgG (8.7 vs. 5.1 g/L, P = 0.02) and IgM (3.7 vs. 1.8 g/L, P = 0.001) was detected in patients with CHF and antibody levels further decreased the days after LT reaching levels comparable to healthy individuals. MARS treatment had no apparent effect on the immunoglobulin profile in patients with ALF or ACLF.Conclusion
We provide evidence that LT reverses hypergammaglobulinemia in patients suffering from CHF within one day, which could be explained to a reconstituted hepatic antibody clearance, whereas MARS treatment has no immediate effect on immunoglobulin levels.Key words: antibodies, immunoglobulins, liver failure, liver transplantation, artificial liver support system, molecular adsorbent recirculating system 相似文献85.

An opaque screen moving overhead elicits an escape response in the crabChasmagnathus that habituates for a long period after just a few presentations. A series of experiments was performed to determine whether the crab’s long-term habituation (LTH) is mediated by an association between contextual cues and the eliciting stimulus.Chasmagnathus failed to exhibit LTH when a visual cue in the experimental environment was changed between training and testing. In addition, long-term exposure to the context in the absence of the eliciting stimulus impaired LTH, both when the exposure preceded the habituation training (latent inhibition) and when the exposure came after the training (extinction). Long exposure to the context alone prior to training also produced a decrease in responsiveness to the eliciting stimulus, which confirmed previous results. However, both effects of long exposure were only manifested when the crabs spent a period of time between exposure and testing out of the experimental context. The results of this paper are interpreted as supporting the view thatChasmagnathus LTH can be understood largely by Wagner’s associative theory of habituation. 相似文献

There are many issues surrounding the performance of critical assets on high-speed ballasted railway lines. At assets like switch & crossings and bridge transitions high track forces can be produced resulting in higher ballast settlements and hence track misalignments. The latter result in higher track forces and hence more settlement, leading to the need for increased track maintenance to ensure comfort and safety. Current technologies for solving issues like ballast movement under high-speed loading regimes are limited. However, a technique that has been well used across the UK and now increasingly overseas to stabilise and reinforce ballasted railway tracks is the application of in-situ polyurethane polymers, termed XiTRACK. This paper discusses how this technique can be used to solve these types of long-standing issues and presents actual polymer application profiles at two typical critical sites, namely a junction and a transition onto concrete slab-track. 相似文献

ABSTRACTIn this research, I analyse the practice of caporales dances in community and school contexts. I put forward some debates around the position of dances in the processes of education and identity definition. I delve into the identification of the caporales with Bolivian migration, poverty and contexts of discrimination. The references are centred on the teaching and performance of these dances in workshops and festivities held by organisations of Bolivian migrants in a town near the city of Buenos Aires. I continue with the analysis of the practices of this dance in school situations and its coexistence with current trends of nationalism in Argentine schools. 相似文献

Parental mentalizing, which is the capacity to understand behavior in terms of mental states and to reflect this back to a child through speech, is a key construct in child development. Adults with high mentalization promote children’s secure attachment, mentalization and self-regulation. This study describes this competency in a sample of teachers from Chilean nurseries in interaction with 12-month-old children during a storytelling scenario and compares it with the children’s mothers. The sample comprised 208 adults (104 teachers and 104 mothers). The adults were asked to tell 2 stories to the children, and these situations were recorded, transcribed, and codified using guidelines that identified 4 references to mental states (desires, cognitions, emotions, and attributes) and 4 references to nonmental states (causal and factual talk, physical states, and connections with the child’s life). Research Findings: The results showed significant differences between the educational staff and the mothers, and the teachers performed better than the mothers in terms of both greater mentalization and a greater number of references to desires, causal talk, emotions, and physical states. Practice or Policy: The results provide evidence regarding the supportive role played by educational staff in children’s development, especially in underprivileged sectors. 相似文献
