Women's Danger Management Strategies in an Inner‐City Housing Project*

The danger management strategies of low‐income African American women who live in a public housing community characterized by chronic violence are examined. Based on qualitative interviews with 18 single mothers, we explored the violent community dangers with which women contend, the nature of this violence, the strategies used to deal with community violence, and their benefits and costs to family and community life. Findings show that multiple types of violence characterized life in the community and that this violence has specific physical locations, a particular set of actors, and a temporal rhythm. Women's responses to violence were nonconfrontational and family focused in nature. These efforts were effective in keeping women and their children safe, but did not reduce the prevalence of violence.

英语听力训练策略使用问题探索

通过对河南中医学院2003级医学班的131名研究生的测试，探讨英语听力训练的策略问题。研究表明，有意识地恰当地使用策略能提高外语学习成绩，因此在他们之中进行了策略使用情况问卷调查，结果发现策略使用的多少与成绩之间虽不呈线性相关关系，但也有一定相关，从而断定策略的掌握会对学生产生积极的影响。然而现在的听力教材中缺少这一内容，于是笔者将其加入到课文的具体内容之中。     

Adopted Children: Core Issues and Unique Challenges

TOPIC: Psychological impact of adoption and resulting core issues for adopted children. PURPOSE: To raise awareness of the psychological impact of adoption. SOURCES: Published literature and personal observations. CONCLUSIONS: Adoption raises unique issues and challenges for the child and adoptive parents. Resolving the issues of adoption is a lifelong process. Through an awareness of the issues inherent in adoption, nurses and parents can use strategies that will enhance children's self-esteem and decrease their emotional vulnerability. Search terms: Adoption, intervention, loss, self-esteem, strategies     

Polylactic acid (PLA) root replica in ridge maintenance after loss of a vertically fractured incisor

Abstract A periodontally affected tooth was prepared for a special treatment: Calcium hydroxide was introduced into the apical half of the root canal whereas its cervical part was filled with glass ionomer cement. The tooth was shortened subgingivally. After 6 weeks of epithelization over the residual root a palatal full-thickness flap was mobilized. The root was carefully extracted and chairside copy-milled from the biodegradable polylactic acid (PLA) material. The PLA-replica was implanted immediately into the socket and the flap was sutured. Aim of the treatment was to prevent the ridge collapse of the extraction area. Ridge height could be preserved during the 21 months of observation. With time the radiographic density of the cancellous bone increased in the implanted area, indicating that a PLA-replica is replaced by host's bone tissue.     

‘You have to learn to live with it’: a qualitative and quantitative study of older people with asthma

Introduction: Asthma mortality has declined overall because of a range of public health initiatives. In western countries, the majority of asthma deaths now occur in people over the age of 50. The reasons for the poorer response of older age groups to public health asthma initiatives are not known. Objectives: We undertook a study to investigate the disease perspectives of older people with asthma and barriers which may exist and prevent optimal asthma care. Methods: Fifty‐five participants (16 male and 39 female) aged over 50 from an inner city, suburban area and a rural region were recruited. Lung function was measured, and questionnaire data on asthma symptoms, knowledge and control, medication use and respiratory health were collected. Participants were also interviewed in‐depth, and the quantitative and qualitative data were triangulated. Results: Participants with a duration of asthma for >30 years reported significantly fewer symptoms and better quality of life irrespective of asthma severity, indicating less appreciation of symptoms in those with a long asthma duration. Interviews revealed this was related to previous asthma management strategies when treatment options were limited. Participants with a recent diagnosis sought understanding of asthma and the reason for their illness. Initiatives to improve asthma care in older people need to reflect these findings. Conclusions: Self‐management strategies for older people need to be tailored according to the time of disease onset and the duration of disease.

Assessment of postoperative pain: impact of clinical experience and professional role

Background: Unrelieved postoperative pain is still reported to be a rather common clinical problem which may be related to inadequate routines for pain assessment. Therefore, the aim of the study was to describe strategies used by experienced and less experienced nurses and physicians in their assessment of postoperative pain and to relate different approaches, clinical experience, and professional role to the accuracy of the pain ratings.
Methods: Data collection was based on repeated interviews with nurses (n=30) and physicians (n=30) in connection with clinical pain assessments (n=180) including VASscoring
Results: Commonly used strategies in the pain assessment were: - how the patient looks, - what the patient says, - the manner of talking, and - past experience of similar circumstances. The mean VAS-score given by the patients (6.1±21.1) was significantly (P<0.001) higher than that rated by the staff members (4.9±21.2). Nurses as well as physicians overestimated low and underestimated high levels of pain indicated by the patients. The accuracy of the ratings by nurses, especially by more experienced ones (≤10 years in nursing), was found to be less precise than that of physicians. The pain assessment of these very experienced nurses was characterized by a systematic underestimation.
Conclusions: The present study emphasizes a need for definition of more precise strategies for clinical postoperative pain assessment which better take into consideration the pain experiences and needs of individual patients
