The literature has shown that academics often share intermediate research resources bilaterally and only infrequently deny requests for sharing. This study goes further and investigates how resource sharing is rewarded. We contrast rewarded and non-rewarded sharing, and further differentiate the types of rewards into direct (e.g., coauthorship) and reputational (e.g., acknowledgments). In a survey of 1,204 resource suppliers or recipients in the UK, Germany, and Japan, we find that rewards are commonly used, and that the form of rewarding is associated with the context in which academics work. In particular, we find that suppliers who are commercially active are more likely to agree on direct rewards. Instead, suppliers who make use of open sharing platforms are more likely to agree on reputational rewards and less likely to agree on direct rewards. For both suppliers and recipients we find that those working in larger teams are more likely to agree on direct rewards, and that their interdisciplinarity is positively linked to direct rewards and negatively to reputational rewards. These results suggest that a reward system for intermediate resources is emerging and rewarding practices are evolving with contextual differences. 相似文献

This study investigated how gender shapes the relationships between classroom environment, achievement goals and maths performance. Seventh-grade students (N?=?498) from five urban secondary schools filled in achievement goal orientations and classroom environment scales at the beginning of the second semester. Maths performance was assessed as an average grade four months later. The results indicated gender differences in the perception of teacher and peers support, achievement goals and maths performance. The effects of goal orientations, teacher and peers support on achievement were moderated by gender. Furthermore, the interaction between classroom environment and performance goals on maths grades varied with gender. In the boys’ sample, performance-avoidance goals interacted with teacher support, while in the girls’ sample, performance-approach goals interacted with peers support in predicting maths grades. The educational implications of these gender differences are discussed. 相似文献

This paper explores the geography of academic engagement patterns of native and foreign-born academics, contrasting how patterns of intranational and international engagement with non-academic actors differ between these two groups. We suggest that foreign-born academics will engage more internationally than their native-born colleagues, whereas native-born academics will have greater levels of intranational engagement. Drawing upon a large multi-source dataset, including a major new survey of all academics working in the UK, we find support for the idea that where people are born influences how they engage with non-academic actors. We also find that these differences are attenuated by an individual’s intranational and international experience, ethnicity and language skills. We explore the implications of these findings for policy to support intranational and international academic engagement. 相似文献

This study evaluated how gender is related to children’s intelligence beliefs, goal orientations and academic achievement and whether there are gender differences in how intelligence beliefs and goal orientations are related to academic achievement. The participants, 362 seventh grade students (55.8% girls; Mage = 13.20, SD = .57 years), completed measures regarding their intelligence beliefs and goal orientations at the beginning of the second semester and the grades were collected at the end of the semester. Girls reported higher scores on incremental belief, mastery goal and higher achievement but lower levels of performance avoidance compared to boys. The relations between intelligence beliefs and academic achievement were fully mediated by both performance goals. Further, there were no gender differences in the associations among intelligence beliefs, goal orientations and achievement. The findings reveal that goal orientations are a mechanism that might explain why intelligence beliefs are linked with academic achievement in early adolescence. 相似文献

This study investigated the role of maturity timing in selection procedures and in the specialisation of playing positions in youth male basketball. Forty-three talented Dutch players (14.66 ± 1.09 years) participated in this study. Maturity timing (age at peak height velocity), anthropometric, physiological, and technical characteristics were measured. Maturity timing and height of the basketball players were compared with a matched Dutch population. One-sample t-tests showed that basketball players were taller and experienced their peak height velocity at an earlier age compared to their peers, which indicates the relation between maturity timing and selection procedures. Multivariate analysis of variance (MANOVA) showed that guards experienced their peak height velocity at a later age compared to forwards and centres (P < .01). In addition, positional differences were found for height, sitting height, leg length, body mass, lean body mass, sprint, lower body explosive strength, and dribble (P < .05). Multivariate analysis of covariance (MANCOVA) (age and age at peak height velocity as covariate) showed only a significant difference regarding the technical characteristic dribbling (P < .05). Coaches and trainers should be aware of the inter-individual differences between boys related to their maturity timing. Since technical characteristics appeared to be least influenced by maturity timing, it is recommended to focus more on technical characteristics rather than anthropometric and physiological characteristics. 相似文献

The aim of this study was to gain a better understanding of how fictional television shapes people’s expectations about the moral workings of the real world, relying on cultivation theory and models of narrative and moral effects as theoretical frameworks. Using a cross-sectional sample of the general German adult population, this study investigated the relationship between television viewing time (overall television and three genres—crime drama, medical drama, sitcoms) and narrative engageability with three idealistic moral expectations (just world beliefs, professional altruism of doctors, tolerance of otherness). Although genre viewing was not related to idealistic moral expectations, overall television viewing and narrative engageability proved to have consistent positive relationships. Results indicate that television viewing, the audience’s eagerness to engage with narratives (narrative engageability), and moral expectations about the real world are intertwined and mutually dependent. 相似文献

ABSTRACTAn understanding of biological variation is important for understanding ecological interactions, ecosystem function, and species’ response to environmental change. Biological variation is essential to species survival because natural selection acts upon the phenotypic variation within a population: the more varied the population’s genetic resources, the more likely that the population will persist into the future. We explored how students think about biological variation by evaluating written assessments and interviews of grades 6–16 students about starting a captive breeding programme for species conservation. We created a qualitative framework that describes levels of proficiency in student ideas about biological variation. Lower level responses reason about attributes related to an individual’s reproduction and survival rather than population-level variability. Student responses at a middle level of sophistication point to the importance of variation but do not link it mechanistically to species survival and resilience. We also describe alternative conceptions related to biological variation and natural selection which exist at all grade levels. Educators can use these findings to inform curriculum and instruction in terms of addressing important concept areas (e.g. variation at the population scale) and some common alternative conceptions that may impact an accurate understanding of natural selection and evolution. 相似文献

This paper provides new insights into understanding the causes of deterioration of the Corbii de Piatra rupestrian church and shows the significance of studying the geological environment of historical rock-cut settlements when undertaking preservation and restoration actions. The Corbii de Piatra church is one of the few rupestrian churches remaining in Romania and is an important part of the country's heritage. The church is carved in a stratum of polymictic sandstone of Oligocene age, which is part of the Getic Depression, located in the southern part of the South Carpathians. In the 14th century the interior walls of the church were decorated with mural paintings of a high artistic value. Over the centuries, the church's walls and mural paintings have been negatively affected by a series of physicochemical processes. These processes were studied through field investigations and laboratory analyses carried out between October 2007 and November 2010. The investigations revealed that tectonic fissuring and the structural anisotropy of the rock facilitate the infiltration of meteoric water through the walls into the interior of the church, from north to south, maintaining a high-level of humidity in the northern wall and in the interior of the church. The most harmful effects observed were: (i) the partial hydrolysis of the feldspars through reaction with water from the pores, producing a friable mass of phyllosilicates which led to a superficial disaggregation of the rock and to a diminished cohesion between the rock and the mortar of the fresco, (ii) the reprecipitation of the gypsum as efflorescences on the northern wall and ceiling, covering the mural painting in localized areas, as a result of the transportation of the gypsum by water from the upper strata, (iii) the alteration of the cinnabar pigment, as a result of water penetration by diffusion through the fresco from the wet rock to the pictorial layer (the secondary effect observed being the formation of sulfuric acid, which further reacted with the carbonate from the fresco to form gypsum), (iv) the development of biotic crusts, predominately algal, on the interior wet walls, which, facilitated by the permanent high humidity and the semi-obscurity of the interior of the church, have covered large surfaces of the fresco. Compared to the interior, the exterior vertical walls have been exposed to prolonged daily and seasonal variations of temperature and humidity. These variations have caused repeated variations in the volume of the sandstone, leading to contraction fissuring and peeling of the vertical walls. Any future procedures that might be used to conserve the church should strive to reduce the humidity of the sandstone in the interior walls. 相似文献
