To investigate the relations among popular measures of neonatal stress and their link to subsequent temperament, 50 full-term newborns from a normal care nursery were examined responding to a heelstick blood draw. Baseline and heelstick measures of behavioral state, heart period, vagal tone, and salivary cortisol were obtained. Recovery measures of behavioral and cardiac activity were also analyzed. Mothers completed Rothbart's Infant Behavior Questionnaire when their infants reached 6 months of age. Baseline vagal tone predicted cortisol in response to the heelstick, suggesting that baseline vagal tone reflects the infants' ability to react to stressors. Greater reactivity to the heelstick (more crying, shorter heart periods, lower vagal tone, and higher cortisol) was associated with lower scores on "Distress-to-Limitations" temperament at 6 months. This finding was consistent with the expectation that the capacity to react strongly to an aversive stimulus would reflect better neurobehavioral organization in the newborn. Recovery measures of cardiac activity approximated and were correlated with baseline measures indicating the strong self-righting properties of the healthy newborn. Finally, vagal tone and salivary cortisol measures were not significantly related, suggesting the importance of assessing both systems in studies of the ontogeny of stress-temperament relations. 相似文献

Scrutiny of intercollegiate athletics has intensified in recent years. This study compares student-athletes with those of non-athletes in terms of their engagement in effective educational practices. Contrary to many reports in the popular media, the findings from this study indicate that, on balance, student-athletes across a large number of colleges and universities do not differ greatly from their peers in terms of their participation in effective educational practices. In most instances, when differences do exist, they favor athletes. 相似文献

Tympanic membrane (TM) temperature asymmetry has been proposed as a phenotypic marker of vulnerability to negative emotionality in children. Little is known about the stability of TM temperatures or how readily one can obtain a reliable index of the phenotype. TM temperatures were collected from 3- to 5-year-old children ( N =73) over 5 months ( Mdn= 34 samples). Seven to 10 samples needed to be aggregated to achieve reliable measures (αs>.70). Using reliable estimates, TM asymmetry remained stable over time, r (72)=.72, p< .01; 70% of the children had warmer left TMs; and TM asymmetry correlated as predicted with measures of children's emotionality. TM asymmetry may be a phenotypic marker of vulnerability to negative emotionality, but measures obtained on one occasion may not reliably index the phenotype. 相似文献

This is the second in a series of articles exploring international trends in health science librarianship in the first decade of the 21st century. The invited authors were asked to reflect on developments in their country - viz. Australia, Canada, New Zealand and the United States. Future issues will track trends in Northern Europe, the Nordic countries, Southern Europe and Latin America. JM. 相似文献

Given the recent trend in bibliometrics and information science to use increasingly complex statistical methods, it is necessary to have powerful toolboxes to work with data from Web of Science (Thomson Reuters). We developed such a toolbox with four specific commands for the statistical software package Stata. These commands refer to (1) the import of downloads from Web of Science to Stata, (2) the preprocessing of address information from authors of publications in the downloaded set, (3) the geocoding of address information, and (4) the calculation of the minimum and maximum distance between several co-authors of a single paper. An advantage of developing commands for an established and comprehensive statistical software package (like Stata) is that a large number of further commands are available for the analysis of bibliometric data. We will describe some of these useful commands as well. 相似文献

The motivation for this research was to understand under what conditions supply chain cooperation might be feasible and under what circumstances it is not. Whereas previous research focuses on dyads in a supply chain, our research seeks to examine a possible factor that can explain why truly cooperative supply chains involving more than two firms are a rarity among independent firms. This research extends the use of game theory to demonstrate the potential impact of a multiple‐tier supply chain agreement. 相似文献

Librarians continually integrate new technologies into library services for health sciences students. Recently published data are lacking about student ownership of technological devices, awareness of new technologies, and interest in using devices and technologies to interact with the library. A survey was implemented at seven health sciences libraries to help answer these questions. Results show that librarian assumptions about awareness of technologies are not supported, and student interest in using new technologies to interact with the library varies widely. Collecting this evidence provides useful information for successfully integrating technologies into library services. 相似文献

The authors examined best practices in university‐level teaching, as premised on the evidence‐based teaching (EBT) literature found in fields external to counselor education. Findings were reported in relation to 3 areas: developing an effective learning environment, structuring intentional learning experiences, and assessing teaching effectiveness. Implications regarding the training of doctoral‐level counselor educators using EBT practices are discussed. 相似文献
