Time series analysis of fertility can improve demographic forecasts. The optimal forecast and its variance for births to an age-structured population subject to serially correlated random fertility are developed. The general case in which the fertility process had arbitrary autoregressive structure is dealt with and then the 4 special cases of white noise, 1st-order autoregressive, 2nd-order autoregressive, and random walk are considered. Consequently, it is determined that the predictions and their variances are highly sensitive to the autoregressive structure of fertility and, therefore, if stochastic models are to be used for prediction, they must emphasize this aspect of the problem. Preliminary empirical efforts to model the time series of U.S. fertility from 1917 to 1972 proved unsuccessful, but it is obvious that at least a 2nd-order autoregressive scheme is require d. The analysis proveded should be helpful in: 1) any application of the procedures requires a successful parameterization of the fertility process; 2) fertility variations could be decomposed into the effects of nuptiality and marital fertility and then births and marriages could be jointly predicted; and 3) the simplifying approximations should be dropped and each age-specific rate could be analyzed and predicted. 相似文献

This study examined the association between physical domestic violence (PDV) and reported child maltreatment in a cohort of children at risk for maltreatment. Participants were 219 6- to 7-year-old children and their caregivers. PDV was measured by combining caregivers' self-reports and children's reports, while child maltreatment was based on state Division of Social Services Central Registry records. Among 219 child-caregiver pairs studied, 42 (19.2%) had at least one maltreatment report in the 2 years following the interviews. PDV consistently predicted child maltreatment, with adjusted odds ratios ranging from 2.96 to 3.46. In addition, we investigated interactions between PDV and other predictors of child maltreatment. Among Aid to Families with Dependent Children (AFDC) participants, PDV was highly associated with child maltreatment. However, this pattern was not observed among subjects who did not have AFDC. There is an increased incidence of child maltreatment reports in families experiencing PDV. AFDC participation intensified the probability of child maltreatment in the presence of PDV. Findings also suggest that in households experiencing PDV, social supports may protect children from maltreatment. 相似文献

This study examined the association between the therapeutic alliance in family therapy and changes in symptom distress, interpersonal relationships, and family coping. The participants (N = 81) were members of low socioeconomic status families referred to a university clinic for in-home family therapy. Participants completed the Outcome Questionnaire, Family Crisis Oriented Personal Evaluation, and the Family Therapy Alliance questionnaires. Regression analyses revealed that the therapeutic alliance explained 19% of the variance in symptom distress changes for mother, 55% for fathers, and 39% for adolescents. The implications of these findings for practicing and researching family therapy are presented. 相似文献

An increasing number of aging community providers and consumers support consumer-direction (CD) in long-term care services. In regard to devolution, consumer-direction goes beyond the usual approach of shifting responsibilities from the federal government to state governments to bring programs "closer to the people." Consumer-direction goes even further by placing resources directly in the hands of consumers. Yet, many questions remain unanswered regarding how to implement CD personal assistance services in general, and especially for older persons. This article describes the importance of examining views from multiple key stakeholders involved in implementing CD programs. We report on three background studies that have informed the Cash and Counseling Demonstration and Evaluation (CCDE) design and implementation-policy expert interviews as well as surveys and focus groups with consumers and representatives. As a fourth data source, we drew upon experiences in designing the CCDE and initial results from the first year of implementation. Each of the three studies on its own provided essential information for planning the CCDE. However, when we examined the studies together, and added CCDE design and implementation experiences, views expressed by the different stakeholders formed a type of multi-perspective "dialogue" that expanded our knowledge about implementing CD services. We hope this increased knowledge will help expand the availability of such services for consumers of any age who want to direct their own care. 相似文献

Self-harm behavior exhibited by adolescents with developmental disabilities can be the most challenging behavior for caregivers and health care professionals to address. Past interventions have taken a behavioral approach and focused on functional analysis to guide assessment and treatment. However, self-harm behavior is becoming more recognized as a means of communication. Therefore, it is important for health care professionals and caregivers to listen to adolescents' attempts to communicate and try to understand the meaning of the behavior. Early assessment is crucial to understanding the meaning of the behavior, and early intervention is necessary to prevent escalation or chronicity. Thorough assessment guides interventions and must be implemented in the context of clients' families and social world, and the broader community. Establishment of trusting relationships among adolescents, their families, and health care professionals is imperative. This article discusses self-harm behavior from a psychosocial perspective related to prevalence, onset, purpose, maintenance, and escalation. It also introduces a comprehensive framework to guide assessment and intervention. 相似文献

The authors examined changes in college students' illicit drug use, patterns of polydrug use, and the relationship between students' ages of initiation of substance use and later use of marijuana and other illicit drugs between 1993 and 2001. Data from 119 US colleges and universities in the Harvard School of Public Health College Alcohol Study were used in the study. They found significant increases in percentages of students' use of marijuana in the past 30 days (from 13% to 17%), past year (from 23% to 30%), and lifetime (from 41% to 47%) between 1993 and 2001, with most of the increase occurring between 1993 and 1997. Past 30-day use of other illicit drugs increased from 4% to 7% and past year use increased from 11% to 14%. More than 98% of marijuana and other illicit drug users used another substance. They also either smoked, were binge drinkers, and/or were users of another illicit drug. Drug prevention programs should emphasize heavy alcohol use and smoking and should start when students are in high school or earlier. 相似文献

Parkinsonian disorders (idiopathic Parkinson's disease and clinically similar disorders) are characterized by impaired movements caused by the degeneration of brain centers involved in regulating normal and smooth movements of the body and its extremities. The mechanisms that cause such degeneration are unknown. This Perspective summarizes research described at a meeting held in June 2003, which was organized by the National Institute of Neurological Disorders and Stroke and the National Institute on Aging to provide an update on recent advances in the cell biology of parkinsonian disorders. 相似文献

This paper presents influence diagnostics for simultaneous equations models. It proposes residuals, leverage and other influence measures. A missing data method is adopted to minimize the masking effect due to case deletions. The assessment of local influence is also considered. The paper shows how to evaluate the effects that perturbations to the endogenous variables, predetermined variables and case weights may have on the parameter estimates. The diagnostics are illustrated with two examples. 相似文献

Thinking possibilistically in a probabilistic world 总被引:1,自引:0,他引:1
Lee Clarke 《Significance》2007,4(4):190-192
We cannot live on the knife edge of disaster all the time. We cannot even think about disastrous extremes with any clarity, says Lee Clarke . For 300 years we have equated thinking probabilistically with thinking rationally, but is that enough for thinking about terrorism, air crashes—or even God? 相似文献

This article reviews research published this century that engages critically with the mantra ‘Breast is Best’ and the associated expansion of official breast‐feeding promotion programmes. In recent years there has been a marked increase in the number of such studies published. They mostly explore experience in English speaking, industrialised countries (the US, Canada, New Zealand, Australia and Great Britain) which are in some social and cultural respects dissimilar, yet where very similar developments and problems are detected in regards to breast‐feeding promotion. We highlight how this exploration of breast‐feeding promotion internationally has developed understanding of wider sociological themes. This scholarship, we suggest, has provided a powerful illustration of the relation between risk society (more particularly a heightened consciousness of risk) and the evolution of a code of conduct that regulates behaviour, that has been termed ‘health moralizm’. The article covers three themes: ‘Science, risk society, authority and choice’; ‘Public health policy and infant feeding’; and ‘Moralization and women’s identity work’. We conclude that the research discussed shows how the sociological imagination continues to shed light on the relation between private troubles and public issues. We also suggest one conclusion that can be drawn from this research is that official discourse and everyday maternal experience appear increasingly distant from each other. 相似文献
