Want that is understood well before say that,think that,and false belief: a test of de Villiers's linguistic determinism on German-speaking children     

Perner J  Sprung M  Zauner P  Haider H 《Child development》2003,74(1):179-188

Two experiments with 79 monolingual German speaking children between 2.5 and 4.5 years showed a consistent developmental gap between children's memory/inference of what someone wanted and what someone wrongly said or thought. For instance, when John is still playing and mother says, "John should be going to bed," more than 70% answered correctly that mother wanted John to go to bed. However, when mother said, "John is going to bed," about 70% answered wrongly that she thought/said that he was still playing. Correct answers emerged with the mastery of the false-belief task. In German, want sentences (about something to happen) obligatorily take the same grammatical that complement as say or think sentences. Therefore, the observed gap constrains de Villier's (1995) linguistic determinism, which claims that acquisition of the necessary grammatical structures for talking about the mind drives children's ability to think about the mind.  相似文献

Effect of sex,class standing,and academic performance on perceived importance of teacher behaviors     

Hubert S. Feild  William H. Holley  Achilles A. Armenakis 《Research in higher education》1976,5(3):215-222

An implicit assumption made in most teaching evaluation instruments is that teaching behaviors are equally important to students. Using specific teacher behaviors which have appeared in a number of teaching assessment devices, the importance of teacher behaviors questionnaire (ITB) was constructed to measure students' perceptions of the importance of selected teacher behaviors. Data collected from 105 college students were utilized in the present study for the following purposes: (a) to determine if there are differences among students' ratings of teaching behaviors in terms of importance and (b) to determine if the ratings of importance given to selected teacher behaviors vary according to students' sex, class standing, or academic performance. Results of the study indicated that there were significant differences in perceived importance of selected teacher behaviors. Furthermore, it was found that ratings of some of these behaviors tended to vary across sex groups. Implications for utilizing importance information as a weighting component in teaching evaluations are discussed.  相似文献   

Sex differences in spatial abilities of medical graduates entering residency programs     

Jean Langlois  Georges A. Wells  Marc Lecourtois  Germain Bergeron  Elizabeth Yetisir  Marcel Martin 《Anatomical sciences education》2013,6(6):368-375

Sex differences favoring males in spatial abilities have been known by cognitive psychologists for more than half a century. Spatial abilities have been related to three‐dimensional anatomy knowledge and the performance in technical skills. The issue of sex differences in spatial abilities has not been addressed formally in the medical field. The objective of this study was to test an a priori hypothesis of sex differences in spatial abilities in a group of medical graduates entering their residency programs over a five‐year period. A cohort of 214 medical graduates entering their specialist residency training programs was enrolled in a prospective study. Spatial abilities were measured with a redrawn Vandenberg and Kuse Mental Rotations Tests in two (MRTA) and three (MRTC) dimensions. Sex differences favoring males were identified in 131 (61.2%) female and 83 (38.8%) male medical graduates with the median (Q1, Q3) MRTA score [12 (8, 14) vs. 15 (12, 18), respectively; P < 0.0001] and MRTC score [7 (5, 9) vs. 9 (7, 12), respectively; P < 0.0001]. Sex differences in spatial abilities favoring males were demonstrated in the field of medical education, in a group of medical graduates entering their residency programs in a five‐year experiment. Caution should be exerted in applying our group finding to individuals because a particular female may have higher spatial abilities and a particular male may have lower spatial abilities.

The Social Embeddedness of Transactions: Evidence from the Residential Real-Estate Industry     

Steve Sawyer  Kevin Crowston  Rolf T. Wigand  Marcel Allbritton 《The Information Society》2003,19(2):135-154

Information and communications technologies (ICT) are becoming pervasive in the residential real-estate industry and their usage is affecting the work lives of real-estate agents. Drawing on data from a regional study of the residential real-estate industry in the United States, we focus on the disintermediation or, more accurately, the reintermediation of real-estate agents in the sales process. Using data collected from interviews, direct observation, and archival records, we examine how real-estate agents are (1) taking advantage of new ICT in their work, and (2) protecting themselves from others wishing to displace their position in the real-estate value chain. Our analysis of this activity draws on two contrasting theoretical perspectives to illuminate the roles of residential real-estate agents: transaction cost and social capital. The results of this study provide insights into the ways in which ICT are used to build and draw on the social relationships that underpin the actual transactions, to help guide the process of buying/selling a house, and to invoke expertise as needed.  相似文献

Identifying the value of data analytics in the context of government supervision: Insights from the customs domain

eCommerce, Brexit, new safety and security concerns are only a few examples of the challenges that government organisations, in particular customs administrations, face today when controlling goods crossing borders. To deal with the enormous volumes of trade customs administrations rely more and more on information technology (IT) and risk assessment, and are starting to explore the possibilities that data analytics (DA) can offer to support their supervision tasks. Driven by customs as our empirical domain, we explore the use of DA to support the supervision role of government. Although data analytics is considered to be a technological breakthrough, there is so far only a limited understanding of how governments can translate this potential into actual value and what are barriers and trade-offs that need to be overcome to lead to value realisation. The main question that we explore in this paper is: How to identify the value of DA in a government supervision context, and what are barriers and trade-offs to be considered and overcome in order to realise this value? Building on leading models from the information system (IS) literature, and by using case studies from the customs domain, we developed the Value of Data Analytics in Government Supervision (VDAGS) framework. The framework can help managers and policy-makers to gain a better understanding of the benefits and trade-offs of using DA when developing DA strategies or when embarking on new DA projects. Future research can examine the applicability of the VDAGS framework in other domains of government supervision.  相似文献   

Sustainability science and the university: pitfalls and bridges to interdisciplinarity     

Marcel Bursztyn 《Environmental Education Research》2014,20(3):313-332

Interdisciplinarity plays a major role in the debate about the sustainability of human societies, in general, and about the crisis and the future of the University. If the twentieth century can be identified as an era of specialization in Academia, there is a tendency now to add interdisciplinary spaces to the traditional disciplinary research and training organization. Non-academic research institutions (NARIs) are showing more flexibility than universities to respond to problem-oriented demands. This article analyzes the current prevalence of a rigid disciplinary academic framework and discusses its limitations in the face of complex demands, such as sustainability science (SS) and technology. Examples from the Brazilian graduate programs in SS are presented to describe some institutional pathologies that usually affect the attempts to achieve interdisciplinarity and SS and technology. Among the main conclusions, are the need for more interaction among universities and NARIs and the need to integrate disciplinarity and interdisciplinarity, rather than continue to deal with them as opposites.  相似文献   

The regulation of release parameters in underarm precision throwing     

Marie A. Dupuy  Denis Mottet  Hubert Ripoll 《Journal of sports sciences》2013,31(6):375-382

The aim of this study was to determine if adults spontaneously exploit the laws of physics to achieve better accuracy when throwing at various distances. Eight adults performed 25 underarm throws at five horizontal circular targets located 4, 5, 6, 7 and 8 m away with a constant 5% relative accuracy requirement. Angle and speed of the ball at release were found to increase with throwing distance, while the coordinates of the release point did not change significantly. These results support the idea that people minimize the variability in impact distance by adapting both the angle and the speed at ball release following a mechanical optimum predicted by the laws of physics. Moreover, variability in distance was found to be less than expected because of independent variations in the angle and speed at ball release. Hence, the control of precision throwing seems to imply compensatory variability, as frequently reported in the control of skilled actions.  相似文献   

Developmental changes and predictability of static strength in individuals of different maturity: A 30-year longitudinal study

Abstract

This longitudinal study analyses the development and predictability of static strength and their interactions with maturation in youth. Of 515 children followed annually from age 6 to 18 years, 59 males and 60 females were measured again at age 35. Early, average, and late maturity groups were established. Body height and mass were assessed. Static strength was measured using handgrip dynamometry. Pearson correlations were used as tracking coefficients. From 6 to 12 years of age, no static strength differences were found to exist between the maturity groups of both sexes. Static strength is significantly higher in early than in average and late maturing boys (age 13–16). In girls, a dose–response effect exists (age 11–14). Adult static strength predictability is low in early maturing boys and late maturing girls. It is moderate to high (50–76%) in the other maturity groups up to age 14. Predictors for adult static strength are childhood and adolescent handgrip dynamometry (in females only), medicine ball throw, sit-up, hockey ball throw, and 25-m sprint. Handgrip is a fair predictor of adult static strength at most ages in early and average maturing females; in average maturing males, it is a predictor at age 11. Other indicators of strength (e.g. hockey ball throw) are predictors in males.  相似文献
