Two neonatal intensive care units (NICU) were observed every 15 minutes for at least 72 consecutive hours. Although infants on both NICUs were exposed to considerable amounts of stimulation, there were differences between the units for each environmental measure in the amount of stimulation and/or the pattern of circadian periodicity. The two NICUs also differed in the amount of time infants spent in various states and in the pattern of state periodicity. In general, the diurnal rhythms of the infant states were associated with the diurnal rhythms of different environmental events; furthermore, the patterns of association were not the same on the two NICUs. The results point to potential problems in depicting a “typical” NICU. More importantly, they suggest that the environmental of NICUs has a recognizable influence on aspects of their inhabitants' behavior and that the nature of influence is different from NICU to NICU. The effects are potentially significant for physical, social, and cognitive development.  相似文献

Infant mental health practice requires the performance of intense emotional labor. Professionals comprising the infant mental health (IMH) field are largely women at seminal points in adult life‐span development. The purpose of this article is to explore the day‐to‐day challenges faced by clinical infant mental health professionals and their perspectives on the supports available for effective job performance. We review reflective supervision as a long‐cherished professional support in the IMH field designed to hold the practitioner's fears, worries, and ambivalence, so that she may return to the work fortified to remain in therapeutic alliance with families despite unsolvable problems and an unknowable future (Weatherston, D., 2009). Yet, we propose that reflective supervision alone may not be an adequate protective measure for a workforce performing intensive emotional labor for extended periods and therefore at potentially increased risk for burnout and high turnover (Hochschild, A.R. 1983 ; C. Maslach, 1982 , C.M. Brotheridge & A.A. Grandey, 2009; A.S. Wharton, 2009 ). We suggest that structural factors concerning organizational culture, flexibility in scheduling, and professional growth and versatility bear deeper examination for their merits in supporting the IMH workforce. Finally, we contend that the overrepresentation of women in practitioner positions in IMH leaves an empirical gap where little is known about the experience of male IMH practitioners and the ramifications of their performance of emotional labor.  相似文献

This study examined the effects of deprivation on engagement in activities for 3 adult men with developmental disabilities. First, an assessment was conducted to identify a high- and a low-preference activity for each participant. Second, the high-preference activity was made available following three amounts of deprivation of the activity (15 min, 2 hr, and 1 to 4 days); the low-preference activity was made available following the schedule of deprivation that produced the highest level of engagement by each participant in the high-preference activity. The results were that 1 to 4 days of deprivation produced the highest average amounts of engagement in the high-preference activity for each participant; this amount of deprivation did not produce high engagement in the low-preference activities. Third, the deprivation procedures and results were replicated when high-preference activities were presented by teachers during the participants' daily activities when their engagement had been quite low.  相似文献

Three pigeons pecked keys for food reinforcers in a laboratory analogue of foraging in patches. Half the patches contained food (were prey patches). In prey patches, pecks to one key occasionally produced a reinforcer, followed by a fixed travel time and then the start of a new patch. Pecks to another key were exit responses, and immediately produced travel time and then a new patch. Travel time was varied from 0.25 to 16 s at each of three session durations: 1, 4, and 23.5 hr. This part of the experiment arranged a closed economy, in that the only source of food was reinforcers obtained in prey patches. In another part, food deprivation was manipulated by varying postsession feeding so as to maintain the subjects' body weights at percentages ranging from 85% to 95% of their ad lib weights, in 1-hr sessions with a travel time of 12 s. This was an open economy. Patch residence time, defined as the time between the start of a patch and an exit response, increased with increasing travel time, and consistently exceeded times predicted by an optimal foraging model, supporting previously published results. However, residence times also increased with increasing session duration and, in longer sessions, consistently exceeded previously reported residence times in comparable open-economy conditions. Residence times were not systematically affected by deprivation levels. In sum, the results show that the long residence times obtained in long closed-economy sessions should probably be attributed to session duration rather than to economy or deprivation. This conclusion is hard to reconcile with previous interpretations of longer-than-optimal residence times but is consistent with, in economic terms, a predicted shift in consumption towards a preferred commodity when income is increased.  相似文献

When an oppressed majority finally gains political power, what happens to its attitudes to its erstwhile oppressor, and to its perceptions and feelings about its socioeconomic disadvantages that were established during its oppression? Longitudinal data from pre- and post-transition surveys of black South African college and high school students indicate marked reductions in perceptions of and outrage about intergroup socioeconomic inequity and deprivation relative to English-speaking and Afrikaans-speaking whites, but no change in attitudes toward these groups or toward whites in general. The findings are discussed in terms of contemporary theory and research on justice, intergroup relations, and group conflict. Some tentative implications for the prospects for a democratic political culture in South Africa are noted.  相似文献

Thirty-two primiparous mothers with their neonates, 20 breast-fed and 12 bottle-fed, were videotaped during feeding longitudinally (at 3, 10 days, 1 and 3 months) in order to investigate whether patterns of mother-infant interaction observed during breast- and bottle-feeding differ also for behavior not directly related to sucking. Infant state, sucking behavior, mother behavior and mother-infant interaction were analyzed by both sequential and non sequential analysis. Results suggest that the method of feedings affects mother-infant interaction observed during and just after feeding also for some behavior not directly related to sucking. The percentage of mutual touch, tactile stimulation and mother's gaze to infant was significantly more elevated during breast-feeding. Independently of the feeding mode, significant sequential dependencies between infant state of alertness and auditory stimulation, and auditory stimulation and mutual gaze were found.  相似文献

A model of family-based intervention for high-risk infants hospitalized in the neonatal intensive care unit and their families is presented. The theoretical underpinnings, principles, and nature of the intervention are described. The adaptation of the model from a clinical–research demonstration project to a clinical consultation service is highlighted, with particular emphasis on the practical application of the model. Domains of the intervention include infant behavior, family organization and functioning, caregiving environment, and home discharge/community resources. Three case illustrations are provided to demonstrate the breadth of the intervention and how it can be individualized based upon the presentation of the infant and family.  相似文献
