Research on family structure has led some to claim that sex‐based parenting differences exist. But if such differences exist in single‐parent families, the absence of a second parent rather than specific sex‐typed parenting might explain them. We examine differences in mothering and fathering behavior in single‐parent households, where number of parents is held constant, and we describe individualist and structuralist perspectives for potential sex‐based parenting behaviors. We compare 3,202 single mothers and 307 single fathers in the Early Childhood Longitudinal Study (Kindergarten Cohort). Results suggest that, although there are small differences in the parenting behaviors of single mothers and single fathers, differences are sensitive to demographic disparities and do not translate to academic deficits for children in either family type. 相似文献

In multistate survival analysis, the sojourn of a patient through various clinical states is shown to correspond to the diffusion of 1 C of electrical charge through an electrical network. The essential comparison has differentials of probability for the patient to correspond to differentials of charge, and it equates clinical states to electrical nodes. Indeed, if the death state of the patient corresponds to the sink node of the circuit, then the transient current that would be seen on an oscilloscope as the sink output is a plot of the probability density for the survival time of the patient. This electrical circuit analogy is further explored by considering the simplest possible survival model with two clinical states, alive and dead (sink), that incorporates censoring and truncation. The sink output seen on an oscilloscope is a plot of the Kaplan–Meier mass function. Thus, the Kaplan–Meier estimator finds motivation from the dynamics of current flow, as a fundamental physical law, rather than as a nonparametric maximum likelihood estimate (MLE). Generalization to competing risks settings with multiple death states (sinks) leads to cause‐specific Kaplan–Meier submass functions as outputs at sink nodes. With covariates present, the electrical analogy provides for an intuitive understanding of partial likelihood and various baseline hazard estimates often used with the proportional hazards model. 相似文献

Causal effects are usually estimated under the assumption of no interference between individuals. This assumption means that the potential outcomes for one individual are unaffected by the treatments received by other individuals. In many situations, this is not reasonable to assume. Moreover, not taking interference into account could result in misleading conclusions about the effect of a treatment. For two-stage observational studies, where treatment assigment is randomized in the first stage but not in the second stage, we propose IPW estimators of direct and indirect causal effects as defined by Hudgens and Halloran (J Am Stat Assoc 103(482):832–842, 2008) for two-stage randomized studies. We illustrate the use of these estimators in an evaluation study of an implementation of Triple P (a parenting support program) within preschools in Uppsala, Sweden. 相似文献

Immigration reforms in the United States initiated in the 1960s are widely thought to have opened the door to mass immigration from Asia and Latin America by eliminating past discriminatory policies. While this may be true for Asians, it is not the case for Latin Americans, who faced more restrictions to legal migration after 1965 than before. The boom in Latin American migration occurred in spite of rather than because of changes in US immigration law. In this article we describe how restrictions placed on the legal entry of Latin Americans, and especially Mexicans, set off a chain of events that in the ensuing decades had the paradoxical effect of producing more rather than fewer Latino immigrants. We offer an explanation for how and why Latinos in the United States, in just 40 years, increased from 9.6 million people and 5 percent of the population to 51 million people and 16 percent of the population, and why so many are now present without authorization. 相似文献

The aim of this investigation was to obtain some baseline self-reported data on the health status and overall quality of life
of a sample of residents of the city of Brandon, Manitoba aged 18 years or older, and to measure the impact of a set of designated
health determinants, comparison standards and satisfaction with diverse domains of life on their health and quality of life.
In May and June 2010, 2,500 households from the city of Brandon, Manitoba were randomly selected to receive a mailed out questionnaire
and 518 useable, completed questionnaires were returned. Baseline health status data were obtained using the 8 SF-36 dimensions
of health and 13 items from the United States Centers for Disease Control and Prevention, Behavioral Risk Factor Surveillance
System. Determinants of health and overall quality of life included measures of socializing activities, a Good Neighbourhood
Index, Social Support Index, Community Health Index, a measure of free-time exercise levels, health-related behaviours, use
of drugs, health care issues, a set of domain-specific quality of life items, a set of measures concerning criminal victimization,
worries and behaviours concerning victimization and the basic postulates of Multiple Discrepancies Theory. Overall life assessment,
dependent variables included Average Health, happiness, a single item measure of satisfaction with life as a whole, a single
item measure of satisfaction with the overall quality of life, the Satisfaction With Life Scale, Contentment with Life Assessment
Scale and a Subjective Wellbeing Index. Using multiple regression, we explained as much as 75% of the variance in Subjective
Wellbeing scores and as little as 45% in happiness scores. Four clusters of health determinants explained from 20% (Happiness)
to 44% (Average Health) of the variance in the dependent variables. Adding comparison standards and domain satisfaction scores
to the set of health determinants increased our total explanatory power by only 2% points for Average Health (from 44 to 46%),
but more than doubled our explanatory power for Happiness (from 20 to 45%) and for satisfaction with the overall quality of
life (from 31 to 67%). As well, our explanatory power for the single item of Life Satisfaction increased from 34 to 66%, for
the Satisfaction With Life Scale from 39 to 74%, for the Contentment With Life Assessment Scale from 36 to 60%, and for Subjective
Wellbeing from 42 to 75%. This provided very clear evidence that self-perceived good health is not equivalent to perceived
quality of life, confirming evidence reported in our earlier studies. The three most important take-home messages from this
investigation are (1) in assessing the relative influence of any alleged determinants of health and the quality of life, different
sets of alleged determinants will appear to be more or less influential for different dependent variables. Therefore, (2)
researchers should use diverse sets of determinants and dependent variables and (3) it is a big mistake to use measures of
health status as if they were measures of the perceived quality of life. 相似文献

This paper is a response to the new book by Alexander Wendt (2015) entitled Quantum Mind. The paper commends Wendt on the book's contribution to our understanding, particularly of quantum mechanics, panpsychism, and externalism in the philosophy of mind. At the same time, it takes issue with Wendt's overall thesis, particularly as it relates to materialism, emergentism, and social structure. 相似文献

People who divorce experience a number of negative impacts, and yet divorce also offers opportunities for growth and transformation. This qualitative study of older adult women offers the possibility that divorce may be sexually empowering, especially for women, based on in-depth interviewing of women who had gone through one or more divorces. Detailed examples of the experiences of fourteen women with divorce and sexual expression are offered, focusing on in which situations divorce might be empowering and how it could contribute to sexual exploration and satisfaction. Overall, for the fourteen women in the study who had experienced divorce, the quality of sex in the marriage impacted the quality of sexual expression after the divorce. Also, these findings supported the idea of transformational learning through divorce, and expand divorce-stress-adjustment and transformational learning perspectives to apply more specifically to sexual expression. Understanding possible impacts of divorce over the lifespan, including strengths-based aspects, is important for social workers as the population they serve ages. 相似文献

The purpose of this study was to evaluate the efficacy of a school-based case management intervention in reducing teen-pregnancy. A nonrandomized intervention/comparison schools mixed-method evaluation design was employed. Participants included 203 pregnant and parenting teens with annual follow-up over a 3-year period. The results indicated that the time to repeat pregnancy was delayed among pregnant teens, high school drop-out rates were reduced among parenting teens, and pregnant teens were less likely to deliver before 36 weeks in the intervention versus the comparison school. Case management at a school setting is a promising approach to decrease repeat teen pregnancy. 相似文献

Recent changes in societal attitudes toward lesbian, gay, and bisexual identities have resulted in more people openly identifying with sexual minority status. Due to research on the effects of denying one's sexual orientation and the negative effects of this, many have advocated for more openness in queer sexual orientation. Compassion means connecting to the suffering of others not by avoiding their pain but instead by identifying it so that the feeling of kindness may emerge. Self-compassion, therefore, involves being touched by and open to one's own suffering, not avoiding or disconnecting from it, generating the desire to alleviate one's suffering and to heal oneself with kindness. The purpose of the research is to understand the impact that being out has on a queer person's self-compassion. The Self-Compassion Scale (SCS) is a 26-item, 5-point Likert measure, where a higher score equated to higher self-compassion and looked at how a person showed loving kindness to one's self through the six dimensions of self-compassion. The six dimensions of self-compassion are mindfulness, over-identification, self-kindness, self-judgment, common humanity, and isolation. Results showed that those who are totally out have a higher sense of self-compassion. Implications for practitioners working with the queer population are also discussed. 相似文献

In the United States alone, millions of listeners tune in to Internet-based audio-on-demand (commonly known as podcast programming). Religious programming is among the fastest-growing podcast areas. Since studies show that evangelicals are known to be quick to adopt new technology, this research involved a content analysis of 67 podcast episodes produced by five well-known renewalist evangelical ministries. The study found most podcasts were not original in content and were not consistently available for listeners to download. Also, the podcasts had poorer production values than would be expected from broadcast programming. A frame analysis identified ministries' justification of religious messages, listener responses sought, and rewards promised to listeners. More research is needed to answer questions about the impact on listeners and compare the content of renewalist program offerings to other Christian podcasts. 相似文献
