The current study examined factors related to leaders' reactions to 360-degree feedback. The total sample consisted of 220 supervising managers from a large public utility. We collected data in three waves which involved pretest, performance rating, and posttest surveys (49 leaders had valid data from all three waves of measurement). We hypothesized that overall ratings, organizational support, and perceived rater ability would be positively related to four reaction criteria (acceptance and perceived usefulness of subordinate feedback and peer feedback). Results showed that overall ratings were related to acceptance of peer and subordinate feedback, but were less consistently related to perceptions of feedback usefulness. For perceived usefulness of subordinate feedback, organizational support accounted for unique variance beyond overall ratings, and perceived rater ability was marginally significant. None of the predictions for perceived usefulness of peer feedback were significant. The authors discuss limitations, implications, and suggestions for future research.  相似文献

Autism spectrum disorder (ASD) diagnoses are increasing, leading to growing demands on the service delivery system to meet the needs of children and families. Further understanding individual enabling components such as perceptions of parents/caregivers and personnel, as well as community-level enabling components such as the availability of and quality of services, may help inform system improvements. In this qualitative study, 19 parents/caregivers of children with ASD in one state in the United States were interviewed regarding their experiences with the ASD service delivery system, as well as their individual responses in relation to these experiences. Emergent themes point to the importance of individual coping strategies such as social support, collaboration with service providers, advocacy and empowerment, determination, and luck. Characteristics of the service delivery system, positive and negative, also were described. Findings can inform the design of future programs, services, and policies to support parent/caregiver coping and improved service delivery.  相似文献

The Council on Social Work Education's (CSWE) Strengthening Aging and Gerontology Education for Social Work (SAGE-SW) project, funded by the John A. Hartford Foundation partnered with the National Committee to Preserve Social Security and Medicare (NCPSSM) to develop an Intergenerational Policy and Advocacy Project (IAP). This curriculum pilot project, based on a community organization model, was conducted with 13 baccalaureate social work (BSW) and master's social work (MSW) programs across the country and 122 students. The project was one method to pursue CSWE SAGE-SW's efforts to infuse aging content into social work foundation curricula, to support intergenerational teaching, to strengthen social work advocacy skills, and to provide social work students with positive experiences working with older adults. Pilot sites were asked to carry out the project as part of an existing course foundation or field practicum course. Project activities included collaboration with a variety of community agencies, holding issues or "town hall" forums in order to educate community members about critical policy issues affecting older adults; making contacts and establishing relationships with local, state and/or federal legislators; and conducting assessments of the service needs of older adults in the students' communities. Questionnaires, feedback, pre-post evaluations as well as brief accounts of each project are presented. Participants considered the IAP to be a successful project in terms of the objectives of increasing awareness and competency among social work students of aging issues and of promoting intergenerational linkages between older people and social work students.  相似文献

Early adolescents benefit most from program opportunities where they can be actively engaged in their own learning and development and where there is a good fit between their developmental needs and the intentional learning opportunities provided by the program. The theoretical framework presented here suggests that the two most important features of an engaging youth program are an intentional ethos of youth development and an intentional strategy to design and implement developmentally appropriate learning experiences. Practical examples from research and community practice are used to illustrate program strategies for early adolescents that emphasize intentional thought, decisions, and actions every step of the way.  相似文献

We examined the separate influences of volunteers' personal motives and their team leaders' behaviors on volunteer satisfaction and contributions, along with mediating processes suggested by self‐determination theory. Participants were 302 volunteers who worked in teams at various sites through a central agency. As predicted, both personal motives for volunteering and transformational leadership influenced volunteer satisfaction through enhanced work meaningfulness and higher‐quality team relationships. However, motives that predicted volunteer contribution were different from those that predicted satisfaction. Whereas satisfaction was positively associated with motives concerning esteem enhancement and value expression, contribution was positively associated with motives to gain understanding and negatively related to motives pertaining to esteem enhancement and social concerns. Transformational leadership was positively associated with volunteer satisfaction, but not with volunteer contributions. The theoretical ramifications of these findings are discussed, along with practical implications for the recruitment and retention of volunteers.  相似文献

This paper describes a systems simulation model of the national economy of Kenya. The model contains an input/output production component linked to a consumption component, disaggregated into nine income classes. Capital formation and government are integrated into the model as interactive elements. The model is demand driven and thus growth rates in the productive sectors are generated endogenously as a function of demand. The model has been used by the Kenyan Ministry of Finance and Economic Planning for forecasting and policy evaluation problems. A contributory factor in the successful implementation of the model is its ability to supply detailed quantitative forecasts which, in a developing country, are not readily available from routine sources. In addition, the model deals explicitly with income distribution and inflation consequences which are issues of current concern to local development planners.  相似文献

Siemens Brief Case Game Supply Chain Simulator provides a practical setting for experiential learning exercises about supply chains. The game, drawing upon an actual situation, models the jobs of nine supply chain activities required to transform an order placed by the customer into a delivered product. Using the detail and complexity of the game, instructors can develop learning exercises that focus on a wide range of supply chain management issues. This paper describes two learning exercises with different objectives and for different audiences that we successfully delivered using the Brief Case Game. One exercise provides a concrete example of typical activities in a supply chain and their interactions. The other exercise leads students to discover what creates a need for coordination, what activities in a supply chain require coordination, and what methods work well. These exercises are suited for small upper level undergraduate and graduate courses in logistics and supply chain management. While significant resources were used to develop exercises and deliver the game, students were enthusiastic about the approach and demonstrated that they learned about the complexity inherent in managing supply chains.  相似文献

Introduction

The following quantitative observational study aimed to analyse the maternal and neonatal outcomes of 90 low-risk pregnant women who gave birth in water at São Bernardo Hospital.

Methods

A form containing information on the obstetric history of the parturient, the type of immersion, and the labour and birth follow-up was used by midwives to collect the data.

Background

The Apgar score (at 1 min after birth) used in this study, called Aqua Apgar, was adapted by Cornelia Enning.

Results

The mean water immersion time was 1 h and 46 min and had an influence on the duration of labour (mean 5 h and 37 min), with a statistically significant difference (P = 0.004). There was a decreased cervical dilatation time and a shorter duration of the expulsion phase. In the immersion scenario, 30% of the women did not undergo any examination to assess the length of the cervix, and 57.8% presented intact perennial areas or first-degree tears. As for neonatal outcomes, during maternal immersion, 97% maintained normal fetal heart rates (between 110 and 160 beats per minute) and Aqua Apgar was higher than 7, both in the first minute (mean of 9.4) and in the fifth minute of life (mean of 9.9).

Conclusion

These safety outcomes, based on sound scientific evidence, should increasingly support and inform clinical decisions and increase the number of waterbirths in health facilities. The results of this study align with growing evidence that suggests waterbirth is a safe delivery option and therefore should be offered to women.  相似文献

Differences in gender and age have been established in the context of crime, violence, and prevalence of risk and protective factors. These studies are often notable only in the Western Hemisphere. Despite growth in crime and violence in the Caribbean Community (CARICOM), relatively little understanding of violence in CARICOM member states exists. In light of these concerns, the major purposes of this study include: (1) comprehensively assessing the scope of the four behaviors (i.e., engagement, victimization, witness, and report) in relation to violence and youth’s perceptions of risk and protective factors in family and school domains, and (2) examining how they differ by youth’s gender and age. This study draws on assessment data on youth violence in five CARICOM Member States: Antigua and Barbuda, St. Kitts and Nevis, St. Lucia, Jamaica, and Trinidad and Tobago using a completed 51-item quantitative questionnaire from approximately 512 students. The results suggest that violence engagement, victimization, witness, and report significantly differed by gender and age. Male students were more likely to engage in violence, but less likely to report such violence to adults. Similarly, older students reported that they were more likely to engage in and witness violence. For risk and protective factors, female students reported significantly higher scores on domestic violence, whereas male students had higher scores on the access to drugs/weapons. Older students also tended to report higher levels of some school risk factors and lower levels of some protective factors in both family and school.  相似文献
