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

Managed care poses numerous opportunities and challenges for today's health care organizations and their employees. This article investigates the ways that hospital nurses develop and make sense of their professional roles and organizational environments in a changing and often uncertain managed care setting. The case study approach used in this research combined qualitative methodologies to gain a rich, detailed, and contextual understanding of nurses' work roles and organizational experiences. After an analysis of interviews with 24 nurses and observations of nurses' communicative activities on one inpatient unit, the complexity of sensemaking and role development in a managed care environment is considered. Conclusions are then drawn regarding the theoretical and pragmatic implications of nurses' communicative processes, as they attempted to develop and understand their roles in a changing organizational context. 相似文献

Our argument in this paper is that the model of literary progression which Bakhtin (1981, 1986) expounds in his writing on the chronotope can generate insight into the processes through which pupils improve their writing. We suggest more generally that there are concepts and clues in Bakhtin's historical model of the development of the European novel and in his theory of dialogue which can be helpful in both the evaluation and teaching of classroom writing. 相似文献

The poor reading achievement of African-American children in urban schools is well established. African-American children from low-income homes may be at particular risk for reading difficulties, although middle-income children often fare poorly as well. Intervention efforts have focused on children in kindergarten through fifth grade. This article suggests that prevention efforts must begin prior to kindergarten entry. Several key variables that may influence young children's performance, including poverty, general oral language skills, dialectal variations, home literacy practices, standardized testing bias, and teacher expectations, are explored. Future directions for research addressing emergent literacy in African-American children are discussed throughout. 相似文献

The application of lasers for the removal of superficial deposits from historic stained glass is a comparatively new field of scientific interest. Experimental studies concerning the behaviour of glass substrates and the corresponding superficial deposits towards different laser wavelengths were carried out. The experiments were performed using wavelengths of λ = 193 nm (ArF-Excimer), 308 nm (XeCl-Excimer), 355 nm (Nd:YAG third harmonic) and 1 064 nm (Nd:YAG fundamental) in comparison to λ = 248 nm (KrF-Excimer). This comparison is due to the fact that the present knowledge is based on the 248 nm wavelength. Specially prepared model glass samples representing the original fragments and samples of organic polymers (formerly used as a protective material for historic stained glasses) were used to study the effects of laser radiation and were subsequently characterised by optical microscopy. 相似文献

Information access is central to library and information science, yet explorations of its conceptual nature have been limited. Given the importance of information access to the discipline, there is a need for research to create a better understanding of the concept and its many roles in all activities and behaviors related to information. Drawing on the theoretical work of Elfreda Chatman, this article proposes that the study of information access can be facilitated through the recognition and examination of the physical, intellectual, and social aspects of information access. These types of access are examined through three case studies in terms of different information behaviors and contexts, with a particular focus on the importance of social access. The article also discusses the future roles that considerations of social access can play in research and theory. 相似文献
