Seventy-nine 3-year olds and their mothers participated in a laboratory-based task to assess maternal hostility. Mothers also reported their behavioral regulation of their child. Seven years later, functional magnetic resonance imaging data were acquired while viewing emotional faces and completing a reward processing task. Maternal hostility predicted more negative amygdala connectivity during exposure to sad relative to neutral faces with frontal and parietal regions as well as more negative left ventral striatal connectivity during monetary gain relative to loss feedback with the right posterior orbital frontal cortex and right inferior frontal gyrus. In contrast, maternal regulation predicted enhanced cingulo-frontal connectivity during monetary gain relative to loss feedback. Results suggest parenting is associated with alterations in emotion and reward processing circuitry 7–8 years later.  相似文献

The information practices of collaborative interdisciplinary researchers, especially in distributed environments, remain understudied. Embracing the naturalistic paradigm, this qualitative case study relies upon semi-structured interviews, snowball sampling, and grounded analysis. Based on interviews with 53 participants from 11 Digging Into Data 3 (DID3, 2014-2016) projects, this study examines the working practices of scholars (library and information science professionals, humanists, and computer scientists) engaging in collaborative, international, data-intensive, publicly-funded interdisciplinary research. Benefits of such work include avoiding redundancy, exploding disciplinary silos, and more ambitious, larger-scale outputs. Challenges and lessons learned center on innovation, flexibility, and failure, translation, intermediaries, divisions of labor and delegation of responsibilities and tasks, conflict resolution, technology, outputs and publication, and timeframe, sustainability, and infrastructure.  相似文献

This paper identifies the need for developing new ways to study curiosity in the context of today’s pervasive technologies and unprecedented information access. Curiosity is defined in this paper in a way which incorporates the concomitant constructs of interest and engagement. A theoretical model for curiosity, interest and engagement in new media technology-pervasive learning environments is advanced, taking into consideration personal, situational and contextual factors as influencing variables. While the path associated with curiosity, interest, and engagement during learning and research has remained essentially the same, how individuals tackle research and information-seeking tasks and factors which sustain such efforts have changed. Learning modalities for promoting this theoretical model are discussed leading to a series of recommendations for future research. This article offers a multi-lens perspective on curiosity and suggests a multi-method research agenda for validating such a perspective.  相似文献

The original C P Snow analysis of intellectual traditions ("the two cultures") highlighted very different world views and ways of proceeding for scientists and non‐scientists and critiqued both cultures for their failure to respond to the challenges of industrialisation and to intersect intellectually. Strong parallels can be drawn with academe today: while new linkages between science and technology have occurred, there has been little intersection with and recognition of the Humanities and Social Sciences and the roles they can play in producing “creative chances” for Australia's strategic development, or of the value of the two cultures “intersecting” in new ways. The future for technological innovation and international competitiveness for Australia lies in melting “Snow” and dissolving the stand‐off between the two “cultures”.  相似文献

In a previous simulation study of methods for assessing differential item functioning (DIF) in computer-adaptive tests (Zwick, Thayer, & Wingersky, 1993, 1994), modified versions of the Mantel-Haenszel and standardization methods were found to perform well. In that study, data were generated using the 3-parameter logistic (3PL) model and this same model was assumed in obtaining item parameter estimates. In the current study, the 3PL data were used but the Rasch model was assumed in obtaining the item parameter estimates, which determined the information table used for item selection. Although the obtained DIF statistics were highly correlated with the generating DIF values, they tended to be smaller in magnitude than in the 3PL analysis, resulting in a lower probability of DIF detection. This reduced sensitivity appeared to be related to a degradation in the accuracy of matching. Expected true scores from the Rasch-based computer-adaptive test tended to be biased downward, particularly for lower-ability examinees  相似文献

This study tested the effects of an entrepreneurship education intervention, the New Youth Entrepreneur curriculum, on lower socioeconomic black high-school students' knowledge of basic and advanced concepts in entrepreneurship. Ninety-five high school sophomores (over 85% black) from a lower socioeconomic neighborhood made up the sample for the experimental design: 51 in the treatment group and 44 in the control group. The two instruments used measured participants' knowledge of basic entrepreneurship concepts and higher cognitive levels of entrepreneurship learning, including comprehension, application, and analysis. The treatment group experienced the New Youth Entrepreneur (NYE) curriculum for one period a day for a semester, while the control group was exposed to basic entrepreneurship concepts at an awareness level as part of a general business education course. It was predicted and found that the treatment group significantly outperformed the control group on all dimensions of entrepreneurship tested. The study results confirm that appropriate curricular innovation can significantly influence the acquisition of entrepreneurship concepts and skills by lower socioeconomic black students. They also confirm that these same students can even be energized to the point of moving from opportunity recognition to initial business implementation.  相似文献
