To characterize infant reactions to jealousy evocation, 94 6‐month‐olds and their mothers were videotaped in an episode where the mothers directed positive attention toward a lifelike doll, and in 2 contrasting interactions: face‐to‐face play and a still‐face perturbation. Cross‐context comparisons of affects and behaviors revealed that jealousy evocation responses were distinguished by diminished joy and heightened anger and intensity of negative emotionality, comparable to levels displayed during the still‐face episode; heightened sadness, with durations exceeding those displayed during still‐face exposure; and an approach response consisting of interest, looks at mother, and diminished distancing, which was more pronounced than that demonstrated during play. Infants' heightened anger and sadness during jealousy evocation correlated with heightened maternal sensitivity and dyadic vocal turn‐taking, respectively, during play; and infants' diminished joy and interest during jealousy evocation were associated with heightened maternal withdrawal and intrusiveness, respectively, during play. Both fear and mother‐directed gaze were greater in girls. The discussion argues for interpreting the infant's mixed and agitated reaction to jealousy evocation as evidence of jealousy. 相似文献

A group of individuals with widely different work roles and experiences got together about a year ago ostensibly to study family therapy. It soon became clear that the group was meeting many varied needs only one of which was the study of family therapy itself. When the group began to prepare a paper on the influence of isolation on the families in family therapy, a number of surprising parallels between the isolated rural families and the study group were discovered. This paper explores some of these parallels in contact and emotional support; approval by others; balancing intimacy and distance; development of symptoms. The most surprising finding was that the functioning of the group was markedly shaped by the environment in which it lived and worked; in short, we had ‘discovered’ the importance of systemic influences on ourselves as well as on the families with whom we work. Within a systemic theoretical approach this paper also examines three major constraints imposed on both families and professionals alike by the larger environmental system: being too close; being geographically isolated; and being in a rural environment. 相似文献

P. Ghosh (1981) has claimed that the convolution of two symmetric multimodal distributions is symmetric and unimodal. A simple counterexample to this claim is constructed by considering the convolution f?f, where f is an appropriate mixture of two normal densities. 相似文献

We devise methods to estimate probability density functions of several populations using observations with uncertain population membership, meaning from which population an observation comes is unknown. The probability of an observation being sampled from any given population can be calculated. We develop general estimation procedures and bandwidth selection methods for our setting. We establish large-sample properties and study finite-sample performance using simulation studies. We illustrate our methods with data from a nutrition study. 相似文献

Obsessive Compulsive Disorder (OCD) is a neurobiological illness characterized by unwanted thoughts and/or images followed by repetitive rituals. About 5 million Americans live with Obsessive Compulsive Disorder. OCD is a manageable illness when proper interventions are utilized. Treatment for OCD is limited due to the lack of adequately trained professionals and the high costs of treatment. Cognitive behavioral therapy (CBT) in conjunction with exposure with response prevention (ERP) is the most effective intervention modality available for OCD. To address the treatment gap, an online, interactive self-help website was developed for those living with OCD without access to an effective intervention. This report will explore development of the OCD Challenge website and future implications of its use. 相似文献

The damaged goods hypothesis posits that female performers in the adult entertainment industry have higher rates of childhood sexual abuse (CSA), psychological problems, and drug use compared to the typical woman. The present study compared the self-reports of 177 porn actresses to a sample of women matched on age, ethnicity, and marital status. Comparisons were conducted on sexual behaviors and attitudes, self-esteem, quality of life, and drug use. Porn actresses were more likely to identify as bisexual, first had sex at an earlier age, had more sexual partners, were more concerned about contracting a sexually transmitted disease (STD), and enjoyed sex more than the matched sample, although there were no differences in incidence of CSA. In terms of psychological characteristics, porn actresses had higher levels of self-esteem, positive feelings, social support, sexual satisfaction, and spirituality compared to the matched group. Last, female performers were more likely to have ever used 10 different types of drugs compared to the comparison group. A discriminant function analysis was able to correctly classify 83% of the participants concerning whether they were a porn actress or member of the matched sample. These findings did not provide support for the damaged goods hypothesis. 相似文献

The term “community” has a long and contested lineage in social analysis and debate. This lineage, however, is not generally recognized in policy and public debates on community and bushfire in Australia. “Community” is thought to be central to bushfire preparedness in Australia, especially in rural areas, but what “community” actually means in this context is vague at best. There is an ever‐present tension between the use of “community” as a reference to locality, a “sense of community” as experienced by residents, and the use of “community” as a rhetorical tool by governments and state agencies. We argue that a rigorous analysis of the concept of “community” is critical to an understanding of the processes involved in preparing for the challenges associated with disaster, in this case bushfires. These broader issues are supported by research (a series of surveys, interviews, and focus groups) carried out with residents living in (predominantly rural) bushfire‐prone areas in the state of Victoria, Australia. Ultimately, we assert that social participation and social networks are likely to be the crucial aspects of community that play a central role in effective bushfire preparedness. 相似文献
