To what extent substitute long term care modifies intergenerational transmission of substance abuse has rarely been investigated. Using register data, we followed a national cohort born 1973–1985 consisting of 1012 national adoptees, 2408 former children from long term foster care, 348/846 environmental siblings of adoptees/foster children, and 952,935 majority population peers, from their 15th birthday to age 27–35. Using Cox regression, we calculated hazard ratios (HR) for hospital care and criminality associated with illicit drug/alcohol abuse, with adjustments for socio-demographic indicators of caring families, and substance abuse in caring and birth parents.  相似文献

BackgroundMany post-partum women hold risky beliefs about perceived therapeutic benefits of sun-exposure in the post-partum period and infancy.QuestionCan a maternity hospital based educational intervention reduce the prevalence of such beliefs among post-partum women?MethodsIn this outcome evaluation of an interventional study, two groups of healthy post-partum women (hospital inpatients) were interviewed, 1–4 days following delivery. The first cross-section (106 women) was recruited prior to in-services for maternity staff; the second (203 women) was recruited after completion of the in-services. Data were compared between the groups.FindingsMore pre-intervention than post-intervention women reported they would expose their baby to sunlight to treat suspected jaundice (28.8% vs 13.3%; p < 0.001) or help his/her skin adapt to the sun (10.5% vs 2.5%; p = 0.003); or use sunlight to manage breastfeeding-associated sore/cracked nipples (7.6% vs 2%; p = 0.026).ConclusionThis simple, effective educational intervention could be implemented in programmes for parents, health professionals and students.  相似文献

In this experimental study we integrate transformational leadership theory with recent theoretical considerations and research on core self-evaluations (CSE) in a contingency approach to leadership. We analyze to what extent high state CSE may represent a substitute for transformational leadership in terms of its influence on follower motivation and performance. In a 2 × 2‐design the relationship between transformational leadership and followers' motivation and performance is compared for followers with high versus low state CSE. Participants (76 students) were randomly assigned to four groups. High or low state CSE was activated through a priming manipulation. After that, participants were presented with a written vignette of a transformational or a nontransformational leader who instructs them to perform the subsequent task, a word-search puzzle. Results reveal that followers' state CSE moderated the relationship between transformational leadership and followers' motivation and performance. As expected, followers' state CSE represents a substitute for transformational leadership. Results are discussed for leadership research and management practice.  相似文献

Recent work has shown that the Lasso-based regularization is very useful for estimating the high-dimensional inverse covariance matrix. A particularly useful scheme is based on penalizing the ?1 norm of the off-diagonal elements to encourage sparsity. We embed this type of regularization into high-dimensional classification. A two-stage estimation procedure is proposed which first recovers structural zeros of the inverse covariance matrix and then enforces block sparsity by moving non-zeros closer to the main diagonal. We show that the block-diagonal approximation of the inverse covariance matrix leads to an additive classifier, and demonstrate that accounting for the structure can yield better performance accuracy. Effect of the block size on classification is explored, and a class of asymptotically equivalent structure approximations in a high-dimensional setting is specified. We suggest a variable selection at the block level and investigate properties of this procedure in growing dimension asymptotics. We present a consistency result on the feature selection procedure, establish asymptotic lower an upper bounds for the fraction of separative blocks and specify constraints under which the reliable classification with block-wise feature selection can be performed. The relevance and benefits of the proposed approach are illustrated on both simulated and real data.  相似文献

Abstract

A random stratified sample of just over 2000 was drawn from staff working in 67 different prisons in Sweden. Questionnaires on working conditions and symptoms of ill health were administered and subjects were given health examinations. Morning plasma Cortisol and gamma glutamyltransferase (g GT) levels were measured and factual information on the prisons was collected for use in the analyses.

There were differences between prisons in terms of both objective and self-reported working conditions which appeared to affect health status, physiological state and sick leave rate. Cardiovascular and hypertensive conditions were found more often among prison staff than among a large reference group made up of many different occupations. Sick leave rates among prison staff, especially those over 45 years old, were very high compared with this reference group. The situation appeared particularly difficult in prisons with a high proportion of drug abusing inmates.

The data allowed the identification of several factors which might counteract the effects of stress at work: a proactive management style, goal consensus among staff, a high degree of decision latitude, satisfaction with work performance and a supportive psychosocial climate.  相似文献

Ecological Momentary Assessment (EMA) was used to investigate associations between, and variations in, ejaculatory control and ejaculation latency time (ELT) over repeated measurements of sexual activities. Differences between measures recorded in partnered or non-partnered settings were also investigated. The sample consisted of 21 male Finns aged 18 years or above, contributing a total of 158 reports of partnered and non-partnered sexual activities over a six-week period. In the context of non-partnered sexual activities, after controlling for within-subjects dependence, ELTs between events were predictive of one another, but ELT did not predict ejaculatory control when measured simultaneously, nor at subsequent events. Also, ejaculatory control could not predict simultaneously measured ELT or ejaculatory control at subsequent events. During partnered sexual activities, both ejaculatory control and ELT could be accurately predicted by observing ejaculatory control at prior events. In this context, ejaculatory control could also reliably predict simultaneously measured ELT. ELT or ejaculatory control during partnered sexual activity could not be predicted by observing ELT at prior events. Between-event correlations were generally low, indicating considerable variation in ejaculatory functioning over time. EMA is a thrifty assessment method for studying variations in ejaculatory function, and is likely suitable for studying sexual dysfunctions in general.  相似文献

Background

Women with childbirth fear have been offered counseling by experienced midwives in Sweden for decades without evidence for its effectiveness, in terms of decrease in childbirth fear. Women are usually satisfied with the counselling. However, there is a lack of qualitative data regarding women’s views about counselling for childbirth fear.

Aim

To explore women’s experiences of midwife-led counselling for childbirth fear.

Method

A qualitative interview study using thematic analysis. Twenty-seven women assessed for childbirth fear who had received counselling during pregnancy at three different hospitals in Sweden were interviewed by telephone one to two years after birth.

Findings

The overarching theme ‘Midwife-led counselling brought positive feelings and improved confidence in birth’ was identified. This consisted of four themes describing ‘the importance of the midwife’ and ‘a mutual and strengthening dialogue’ during pregnancy. ‘Coping strategies and support enabled a positive birth’ represent women’s experiences during birth and ‘being prepared for a future birth’ were the women’s thoughts of a future birth.

Conclusions

In this qualitative study, women reported that midwife-led counselling improved their confidence for birth through information and knowledge. The women experienced a greater sense of calm and preparedness, which increased the tolerance for the uncertainty related to the birthing process. This, in turn, positively affected the birth experience. Combined with a feeling of safety, which was linked to the professional support during birth, the women felt empowered. The positive birth experience strengthened the self-confidence for a future birth and the childbirth fear was described as reduced or manageable.  相似文献

Material deprivation is represented in different forms and manifestations. Two individuals with the same deprivation score (i.e. number of deprivations), for instance, are likely to be unable to afford or access entirely or partially different sets of goods and services, while one individual may fail to purchase clothes and consumer durables and another one may lack access to healthcare and be deprived of adequate housing. As such, the number of possible patterns or combinations of multiple deprivation become increasingly complex for a higher number of indicators. Given this difficulty, there is interest in poverty research in understanding multiple deprivation, as this analysis might lead to the identification of meaningful population sub-groups that could be the subjects of specific policies. This article applies a factor mixture model (FMM) to a real dataset and discusses its conceptual and empirical advantages and disadvantages with respect to other methods that have been used in poverty research. The exercise suggests that FMM is based on more sensible assumptions (i.e. deprivation covary within each class), provides valuable information with which to understand multiple deprivation and is useful to understand severity of deprivation and the additive properties of deprivation indicators.  相似文献
