Rehousing of elderly people in Australia has generally not been preceded by research into the kind of assistance that is necessary. An example is given of how an attempt was made to discover the needs of the elderly disabled in a small country community. Assessment by observation of people at home revealed the need for assistance for them to stay where they were. Home Care organized from the district hospital is often a more appropriate answer to this problem than the building of expensive and unnecessary institutions. 相似文献

Previous studies examined how mood affects children's accuracy in matching emotional expressions and labels (label‐based tasks). This study was the first to assess how induced mood (positive, neutral, or negative) influenced five‐ to eight‐year‐olds' accuracy and reaction time using both context‐based tasks, which required inferring a character's emotion from a vignette, and label‐based tasks. Both tasks required choosing one of four facial expressions to respond. Children responded more accurately to label‐based questions relative to context‐based questions at the age of five to seven, but showed no differences at the age of eight, and when the emotional expression being identified was happiness, sadness, or surprise, but not disgust. For the context‐based questions, children were more accurate at inferring sad and disgusted emotions compared with happy and surprised emotions. Induced positive mood facilitated five‐year‐olds' processing (decreased reaction time) in both tasks compared with induced negative and neutral moods. Results demonstrate how task type and children's mood influence children's emotion processing at different ages. 相似文献

This research project examined the individual and combined effectiveness of an HIV prevention workshop and a free condom distribution program in four high schools in Tijuana, Mexico. Adolescents (N = 320) completed baseline measures on sexual practices and theoretical correlates and participated in a two‐part study. In Study I, students were randomly assigned to an HIV prevention workshop or a control condition, with a 3‐month follow‐up assessment. Results indicate three significant workshop benefits regarding HIV transmission by altering sexual initiation, access to condoms, and traditional beliefs regarding condoms. In Study 2, we set up a condom distribution program at two of the participating schools, and students completed a 6‐month follow‐up assessment. Results indicate that exposure to the workshop followed by access to the condom distribution program yielded two beneficial results for reducing HIV transmission: moderating sexual initiation and increasing condom acquisition. Access to the condom distribution program alone had no effects on behavioral and psy‐chosocial correlates of HFV transmission. We discuss implications of these results. 相似文献

The current study examines general text messaging tendencies, patterns of and reasons for texting family members, and the impact of texting on familial relationships among a young U.S. adult sample. Participants were recruited through Facebook; they then completed an online questionnaire. Data from 127 young adults (men: 38; women: 87; unidentified: 2) are analyzed and compared by gender. Findings suggest that young adults text at high rates per month. Participants generally report a prompt response to texts and their ability to honestly express feelings within these messages. Results also suggest participants text family members for a variety of reasons, such as to convey information, plan activities, and engage in general conversation. Distinct gender differences, however, are evident regarding who men and women text as well as texting's effects on familial relationships. Overall, these findings expand researchers’ understanding of texting in general and its impact within the family. 相似文献

This article explores identity work and emotion management in felony domestic violence stalking cases, using data collected in a domestic violence unit in a large metropolitan district attorney's office. Victim narratives in crime reports, intensive interviews of stalking victims, and participant observation in a stalking survivors' support group show how women become “victims” in the criminal justice system. Sometimes women's continued interaction with both stalkers and law enforcement actors affects their ability to create and sustain credible victim identities. Almost any action a victim takes or presentation she makes has the potential for inducing negative identity attributions. Thus identity dilemmas seemingly inhere in the stalking situation. 相似文献

Event history models, also known as hazard models, are commonly used in analyses of fertility. One drawback of event history models is that the conditional probabilities (hazards) estimated by event history models do not readily translate into summary measures, particularly for models of repeatable events, like childbirth. In this paper, we describe how to translate the results of discrete-time event history models of all births into well-known summary fertility measures: simulated age- and parity-specific fertility rates, parity progression ratios, and the total fertility rate. The method incorporates all birth intervals, but permits the hazard functions to vary across parities. It can also simulate values for groups defined by both fixed and time-varying covariates, such as marital or employment life histories. We demonstrate the method using an example from the National Survey of Family Growth and provide an accompanying data file and Stata program. 相似文献

One of the difficulties in evaluating leadership development is measuring whether and how people change over the time period of the leadership development initiative. Even when change over time is an inherent part of the design and evaluation of leadership development, events may occur outside of the control of evaluators that limit the effectiveness of adequately and accurately assessing change over time. With data from a leadership development initiative designed to account for change over time, this article suggests hierarchical linear modeling (HLM) as a multilevel methodological technique to assess change over time in a leadership development context. This article will use real change over time data from a leadership development initiative and discuss the logic and rationale of HLM. We use HLM as an example of a multilevel methodological tool to investigate typical change over time questions in leadership development evaluation. 相似文献
