The role of subsequent school contexts in the long-term effects of early childhood interventions has received increasing attention, but has been understudied in the literature. Using data from the Chicago School Readiness Project (CSRP), a cluster-randomized controlled trial conducted in Head Start programs, we investigate whether the intervention had differential effects on academic and behavioral outcomes in kindergarten if children attended high- or low-performing schools subsequent to the preschool intervention year. To address the issue of selection bias, we adopt an innovative method, principal score matching, and control for a set of child, mother, and classroom covariates. We find that exposure to the CSRP intervention in the Head Start year had significant effects on academic and behavioral outcomes in kindergarten for children who subsequently attended high-performing schools, but no significant effects on children attending low-performing schools. Policy implications of the findings are discussed.  相似文献

Vision plays a privileged role in social interaction and the construction of intersubjective reality. Given that one of sociology's tasks is to problematize the taken for granted, research that examines rarely foregrounded non‐visual modes of sensory perception is a powerful resource. This article draws on twenty‐seven interviews that explore blind people's perceptions of male and female bodies. I highlight several distinctive features of non‐visual sex attribution (salience, speed, and diachronicity), and argue that conceptions of sex as “self‐evident” primarily reflect visual perception. These findings suggest the need to explore the sociology of perception as a new approach to the sociology of the body, and more broadly highlight the role of sensory perception in the social construction of reality.  相似文献

Decentralized wastewater management (DWWM) has recently gained much attention in wastewater management (WWM) due to its build-as-you-go principal. Rapid urban development and the widespread impact of wastewater require sustainable ways to test the DWWM approach. This paper aims to examine and discuss the potential of Bangkok’s current WWM approaches for urban development, focusing on decentralized management approaches. General WWM approaches were examined using case study research methods. Three WWM cases were selected for detailed investigation. Residential wastewater user surveys and expert interviews were used to support system performance findings of service providers and recipients, as well as to draw lessons learned. Results show that DWWM is economically and technically efficient, demonstrating potential for sustainable urban development (SUD) in the study area. The competitive cost found is a result of less sewer line, simple technology, and limited additional costs, while the high efficiency is a result of good operation and maintenance. Also the reclaimed water has been used for landscape irrigation of the urban greenery. Sustainability of the system lies in social value of public amenity it provides, and the urban planning implication that it could be an option for smart growth. The results also show that even in an inner urban area DWWM does not conflict with any SUD considerations. Thus, the study recommends using DWWM for new development within both public and private properties based on Bangkok’s case as part of long-term urban development.  相似文献

We present data on predictors of treatment outcome for 3200 consecutive referrals to a child and adolescent psychiatry clinic. Using Reliable Change Index (RCI) methodology, we divided children into those who, between intake and discharge, improved, stayed the same, or got worse according to clinician-rated impairment. Most predictors of improvement were related to parent variables (marital status, maternal anxiety, and ethnicity), while those associated with deterioration were tied to child status (extent of psychiatric comorbidity, history of placement in a self-contained classroom, and a prior trial of psychotropic medications). The implications of these findings for data-driven program development, clinic management, treatment planning, and systems of care are discussed.  相似文献

Specific efforts by hospital accreditation organizations encourage renovation of nursing stations, so nurses can better see, attend, and care for their patients. The purpose of this study was to examine the effect of nursing station design on the therapeutic milieu in an adult acute care psychiatric unit. A repeated cross-sectional, pretest-posttest design was used. Data were collected from a convenience sample of 81 patients and 25 nursing staff members who completed the Ward Atmosphere Scale. Pretest data were collected when the unit had an enclosed nursing station, and posttest data were collected after renovations to the unit created an open nursing station. No statistically significant differences were found in patient or staff perceptions of the therapeutic milieu. No increase in aggression toward staff was found, given patients' ease of access to the nursing station. More research is needed about the impact of unit design in acute care psychiatric settings.  相似文献

Older adults with multiple pre-existing conditions are admitted to hospitals with acute illnesses and injuries every day. Delirium is not recognized by clinicians across health care settings. With awareness of risk factors and knowledge of delirium, nurses can play a pivotal role in the early identification, treatment, and, most important, prevention of delirium in older adults. Nurses often display a lack of knowledge related to delirium and the complex symptoms that appear differently in the presence of other complicating co-morbid conditions in aging adults. Nurses play a crucial role in keeping patients safe and ensuring optimal outcomes, regardless of the setting. With the growing population of older adults and the expected increases in chronic illness and dementia, delirium is a problem nurses are likely to experience in all practice settings. Knowing what to look for facilitates recognizing the risk and acting early to minimize (or even prevent) delirium.  相似文献

Adherence to a medication regimen can be challenging for children and adolescents with mental health disorders. Medication education can be a beneficial tool for nurses to help promote adherence to psychotropic medications. This article describes an initiative to improve medication education offered to children and adolescents and their families on an acute child and adolescent inpatient unit in a mental health facility. Strategies included adding a game to medication education groups, creating and distributing medication education handouts, and developing and implementing medication education sessions for parents. When used by the patients and families, the interventions were appreciated. Having successful interventions in place may help meet the diverse educational needs of this population as nurses seek to improve medication adherence.  相似文献

Our study examines risk factors for metabolic syndrome on admission to an acute psychiatric facility and the incidence of medical referrals at discharge. Data on demographics, risk factors for metabolic syndrome, other health risk factors, medications, related diagnoses, and primary care providers and referrals were collected from 125 psychiatric patient charts. Comparison analysis was done for two groups: those with two or more risk factors for metabolic syndrome and those with less than two risk factors. Differences between groups were statistically significant for age, waist circumference, body mass index, high-density lipoprotein, triglycerides, and fasting glucose levels. Few patients were referred to their primary care provider for follow-up care. This study has clinical implications for improving assessment of psychiatric patients at risk for developing metabolic syndrome, for designing interventions to help patients adopt lifestyle changes to mitigate these risks, and for working toward fuller integration of psychiatric and primary care.  相似文献

In the family therapy literature there is increasing interest in the dialogical approach, particularly as it becomes well‐grounded in psychotherapy research. One embodiment is ‘open dialogues’, which has developed over a 30‐year period in Western Lapland, Finland. This paper outlines my experience of visiting Keropudas Hospital in Tornio, Finland, the birthplace of open dialogues. It explores the seven theoretical principles of open dialogues, associated elements of clinical practice, and the therapist use of self. The author utilises these aspects to reflect on dialogical moments through words and images based on three conceptual themes, which illustrate the relevance of open dialogues for family therapy practitioners and their contexts.  相似文献
