School success is closely linked to intelligence but also to non-cognitive factors such as achievement motivation. The present study examines which non-cognitive factors predict secondary school grades and looks at reasons why female students tend to outperform their male counterparts. A sample of 554 German freshman students provided measures of general intelligence, achievement motivation, science course choice, self-efficacy, self-perceived academic achievement, and test anxiety. Results show that achievement motivation, self-perceived academic achievement, and sex significantly contribute to the final secondary school success above intelligence. Females’ advantage in final secondary school grades becomes even larger after controlling for general intelligence. This advantage can be explained by females’ higher achievement motivation. Showing more compensatory effort as well as self-control and taking more pride in their own productivity helps females to outperform their male counterparts at secondary school.  相似文献

Using an updated version of the Aging Semantic Differential, 534 younger, middle age, and older participants from a college community rated female and male targets categorized as ages 21–34 and 75–85. Participants also provided views about their own aging. Repeated measures of analysis of variance examined attitudinal differences by age and gender of targets, and by participant age and gender. Female targets were viewed more positively than males by most rater groups. Older targets were viewed more positively by older participants than by other age groups. Older participants had more positive views about their own aging than did participants of younger or middle ages.  相似文献

Self-directed learning with authentic and complex problems (problem-oriented learning) requires that learners observe their own learning and use additional information when it is appropriate (e.g. hypertextual information in computer-supported learning environments). Research results indicate that learners in problem-oriented learning environments often have difficulties using additional information adequately, and that they should be supported. Two studies with a computer-supported problem-oriented learning environment in the domain of medicine analysed the effects of strategy instruction on the use of additional information and the quality of the problem representation. In Study 1, an expert model was used for strategy instruction. Two groups were compared: one group with strategy modelling and one group without. Strategy modelling influenced the frequency of looked-up hypertextual information, but did not influence the quality of learners' problem representations. This could be explained by difficulties in applying the general hypertext information to the problem. In Study 2, the additional information was presented in a more contextualised way as graphical representation of the case and its relevant concepts. Again, two groups were compared: one with a strategy instruction text and one without. Strategy instruction texts supported an adequate use of this graphical information by learners and had an effect on the quality of their problem representations. These findings are discussed with respect to the design of additional help systems in problem-oriented learning environments. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

During the last decades, there has been increasing interest in the role of the university as a key stakeholder and agent in innovation and regional development. In the face of new technologies, especially growing digitalisation and new societal and economic challenges, this paper proposes to reconsider the role of the university in the innovation system. More particularly, we introduce the idea of a business model for the entrepreneurial university of the future and develop nine conceptual theses. The theses are based on four elements of a business model concept: value proposition, creation, delivery and capture. With the help of the nine theses, we aim to trigger new discussions regarding policy implications for the future university in Europe.  相似文献

ABSTRACT

Chalconatronite, Na2[Cu(CO3)]2·3H2O, is formed as a corrosion product when copper alloys are exposed to sodium carbonate solutions in the air. This also happens when metals come into contact with corroding soda glass which forms alkaline surface films in reaction with humidity from clean air. More often, substantial amounts of formaldehyde are present indoors which react to formate via the Cannizzarro reaction and accumulate over time in the films. Twenty cases of chalconatronite (including two mentioned in the literature) are reported as occurring on heritage objects with glass in contact with copper alloys: Baroque reliquaries with set glass gems, enamel on metal (sixteenth century and a modern replica of intentionally unstable composition), Christmas tree glass baubles with wires, glass buttons with metal shanks, a glass figure with a wire support, miners’ lamps, and a glass framed daguerreotype. These confirmed identifications might help conservators in investigating similar cases to shed more light on the formation conditions.  相似文献

A sodium copper formate, first described in 2002, can also form on copper alloys with sodium originating from soda glass hydrolysis. The frequent occurrence (50% of 250 cases of glass-induced metal corrosion) is due to the presence of formaldehyde emissions in storage and its direct reaction to formate in the alkaline surface films. The compound can be produced without the presence of acetate when chalconatronite or metal coupons immersed in soda solution are exposed to formaldehyde vapours. The crystal structure, derived from X-ray powder diffraction, yielded the sum formula Cu4Na4O(HCOO)8(OH)2·4H2O. Except for the absence of acetate in the structure, this is in good agreement with the 2002 publication. To assess which kind of combined glass/metal objects are affected, a number of large museum collections were surveyed. Sodium copper formate was detected as a corrosion product using mainly micro-Raman spectroscopy, for instance, on 18 painted Limoges enamels, eight glass vessels with metal mountings, glass beads on metal wire from 11 bridal crowns, nine Christmas tree balls with wire decoration, 40 pieces of jewellery with glass gems, three daguerreotypes, and one miniature with cover glasses.  相似文献

OBJECTIVE: There has been relatively little attention given to positive adaptation following childhood sexual abuse (CSA), and typically such resilience has been explored primarily in the intrapersonal domain. This study explored questions about later resilience following CSA within a multidimensional framework by assessing resilience across intrapersonal, interpersonal, and intrafamilial domains. METHOD: This community sample consisted of 79 mothers with a history of CSA who had a child living at home with them. Participants completed four outcome measures (Center for Epidemiologic Studies--Depression Scale, Parenting Stress Index [PSI] Health Scale, PSI Parenting Competence Scale, and a measure of marital satisfaction). Risk and protective factors examined in relation to outcome included mother's age, socioeconomic status, severity of the CSA experience, coping strategy (avoidance, seeking social support, and problem solving), child characteristics, and spousal/partner support. RESULTS: Results indicated that when multiple adaptational domains were assessed, mothers showed discrepancies in how adequately they functioned across domains. While severity of the CSA experience was only weakly associated with outcome, use of avoidant coping emerged as a significant risk factor and was strongly and consistently associated with negative outcome across domains. Spousal/partner support was a strong protective factor and buffered the relationship between depressive symptoms and parenting competence. Difficult child characteristics were significantly associated with mothers' perceptions of physical health and parenting competence. CONCLUSIONS: The findings suggest the importance of comprehensive multimethod assessments of resilience and extend the knowledge of factors associated with positive outcome. The results highlight the need for further research exploring current contextual risk and protective factors associated with resilience in each domain.  相似文献
