All languages employ certain phonetic contrasts when distinguishing words. Infant speech perception is rapidly attuned to these contrasts before many words are learned, thus phonetic attunement is thought to proceed independently of lexical and referential knowledge. Here, evidence to the contrary is provided. Ninety‐eight 9‐month‐old English‐learning infants were trained to perceive a non‐native Cantonese tone contrast. Two object–tone audiovisual pairings were consistently presented, which highlighted the target contrast (Object A with Tone X; Object B with Tone Y). Tone discrimination was then assessed. Results showed improved tone discrimination if object–tone pairings were perceived as being referential word labels, although this effect was modulated by vocabulary size. Results suggest how lexical and referential knowledge could play a role in phonetic attunement. 相似文献

The present study identifies characteristics of individuals and work settings that influence Asian international faculty members’ intentions to continue their employment in US research universities. Given the demand for researchers in science, technology, engineering and mathematics fields (STEM), the higher rate of turnover among untenured faculty, and the replacement costs associated with turnover in STEM, the sample is limited to assistant professors employed in these areas. Multinomial regression analyses are conducted to identify variables that “pull” and “push” uncertain faculty toward intentions stay and leave their current institutions. The results suggest that faculty who are more satisfied with time available for research and those who express stronger organizational commitment are more likely to say they will stay. Those dissatisfied with the fairness of work evaluations and believe tenure decisions are not merit-based, are more likely to say they will leave. 相似文献

Despite official government srt (in various jurisdictions around the world) for providing students with opportunities to construct
their own knowledge within the context of formal schooling, school science systems continue to place greatest priority on
teaching and learning of products of science (e.g., laws and theories), while compromising students’ opportunities to develop realistic conceptions about science and expertise for doing science. Based on qualitative data analyzed using constant comparative methods (based on constructivist grounded theory),
we found this also to be the case – paradoxically – in a school belonging to the Canadian Coalition for Self-directed Learning
(CCSDL). Schools in this coalition espouse, among various goals, enabling students to construct their own knowledge, in ways
and directions suiting their individual needs, interests, perspectives, and abilities, in addition to gaining access to knowledge
developed by society. The science department within the coalition school in this study experienced considerable difficulty
realizing this goal, despite school-level administrative support for a concerted effort to reinvent itself along these lines.
Factors that appeared to influence the science department’s efforts included those in each of Schwab’s (1969) educational
"commonplaces;” that is, the curriculum, teachers, students, and the milieu surrounding teaching and learning. Further analysis suggests that results can be explained through reference to a Kuhnian
(1962/1996) paradigm conflict – in which the school’s administrative and curricular committee and other members of the CCSDL
were unsuccessful in convincing members of the science department (who, in turn, appeared to be supported by the provincial
government, parents, and students) to make provisions for more student-directed, openended science inquiry. Assuming that
student-led scientific inquiry continues to be an important curricular goal, efforts must continue to be made, therefore,
to convince members of the mainstream paradigm that it is a worthy goal. 相似文献

Research Findings: Digital play is now commonplace in many young children’s lives, but not in preschool settings. This situation is likely due to the fact that the existent literature seldom highlights what digital play looks like, the various ways it can be situated, and what young children do when they play together with digital devices in the preschool setting. The present study addresses this limitation by providing a close examination of the social interactions of young children as they engage with different types of iPad apps and each other. Observational data of 20 dyads of children during digital play analyzed qualitatively revealed that children exhibited a range of social behaviors from competitive to collaborative as they engaged in 4 types of digital play: practice/task, exploratory, construction, and pretense. Forms of play and exhibited behaviors were shaped by interrelated factors of children’s individual characteristics and relationships, classroom culture and routines, adult views and actions, as well as aspects of the digital device itself. Practice or Policy: Selecting open-design apps, attending to digital play structures, and monitoring peer play more closely may lessen competition, enhance collaboration, and lead to more complex digital play. 相似文献

The relative age effect (RAE) describes an overrepresentation of players born early (Q1) in a selection year and is highly prevalent within youth sport pathways. However, a dearth of research has investigated the RAE at the “super-elite” level. The present research assessed the presence of RAE in super-elite performers. Study 1 investigated RAEs in the world’s best international Test cricketers (N = 262) over a 20-year period according to a robust and stringent “super-elite” criteria. Results revealed the RAE (Q1) when all disciplines were combined. Upon closer examination, this effect was also observed for the batting and spin bowling disciplines, whereas no RAE was found for the pace bowling discipline. Study 2 investigated RAEs in super-elite rugby union players (N = 691) over a 20 year period. Results revealed the RAE for backs (Q1) and a reversal of the traditional RAE (Q4) for forwards, and when all rugby union positions were combined. These findings provide new evidence of RAEs at the super-elite level and present both inter and intra sports differences. Potential explanations for these findings are explored, owing to the survival and evolution of the fittest concepts, and the implications for future research and applied practice are presented. 相似文献

Identifying antecedents of salesperson performance is a long‐standing objective in the sales management research field. The purpose of this article is to outline how the practical understanding of, and the willingness to embrace, sales employees' cultural value‐systems adds value while considering performance drivers, individualistic versus collectivistic values, and performance outcomes. The cultural dimensions under consideration, individualism and collectivism, cannot be approached as a dichotomy. As is the case for all cultural dimensions, they represent a continuum and not absolutes. In this study, the work preferences and predispositions of participants were compared using an international data set. Respondents were culturally classified based on research (i.e., Americans and Australians as individualists and Japanese and South Koreans as collectivists). Specifically, it was found that individualists were less attached to their current work situation; collectivists indicated less work/family conflict; and individualists valued independent work more while collectivists valued deciding work time. This is important because of the need to understand how to effectively connect with the values of people to encourage positive performance outcomes. The reality is that value holds differing degrees of emphasis; the performance formula is the theoretical framework to guide this research. The implications of the results for sales management professionals are discussed. 相似文献
