This paper explores the role and importance of the relationship in the treatment of a young foster child. Because of parental neglect and loss, the child related in an inauthentic manner in order to engage her parents. Her manner of relating arose from old patterns, which were defensive adaptations to traumatic situations. The authors employ a relational theory of the self to conceptualize the processes from an intrapsychic and interpersonal perspective. The paper emphasizes that all the interactions between child and therapist, both in and out of the traditional therapy office, converged into a multidimensional authentic relationship. The authors define this relationship experience as the life space and believe that the establishment of the life space contributed to progress in the therapy.  相似文献

A novel extension of traditional growth models for exposure assessment of food-borne microbial pathogens was developed to address the complex interactions of competing microbial populations in foods. Scenarios were designed for baseline refrigeration and mild abuse of servings of chicken broiler and ground beef Our approach employed high-quality data for microbiology of foods at production, refrigerated storage temperatures, and growth kinetics of microbial populations in culture media. Simple parallel models were developed for exponential growth of multiple pathogens and the abundant and ubiquitous nonpathogenic indigenous microbiota. Monte Carlo simulations were run for unconstrained growth and growth with the density-dependent constraint based on the "Jameson effect," inhibition of pathogen growth when the indigenous microbiota reached 10(9) counts per serving. The modes for unconstrained growth of the indigenous microbiota were 10(8), 10(10), and 10(11) counts per serving for chicken broilers, and 10(7), 10(9) and 10(11) counts per serving for ground beef at respective sites for backroom, meat case, and home refrigeration. Contamination rates and likelihoods of reaching temperatures supporting growth of the pathogens in the baseline refrigeration scenario were rare events. The unconstrained exponential growth models appeared to overestimate L. monocytogenes growth maxima for the baseline refrigeration scenario by 1500-7233% (10(6)-10(7) counts/serving) when the inhibitory effects of the indigenous microbiota are ignored. The extreme tails of the distributions for the constrained models appeared to overestimate growth maxima 110% (10(4)-10(5) counts/serving) for Salmonella spp. and 108% (6 x 10(3) counts/serving) for E. coli O157:H7 relative to the extremes of the unconstrained models. The approach of incorporating parallel models for pathogens and the indigenous microbiota into exposure assessment modeling motivates the design of validation studies to test the modeling assumptions, consistent with the analytical-deliberative process of risk analysis.  相似文献

Abstract The purpose of this research was to explore and explain the role housing plays in rural community vitality. Community vitality refers to economic strength and social well‐being. In spring 2002 we collected primary interview data from informants in 134 small rural communities in nine north‐central states and identified related secondary data from the U.S. census. We developed a structural‐equation‐path model, which supported a “housing decision chain” that influenced community vitality. Based on this research, local housing decisions do play an important role in community vitality. Strong local leaders use housing planning to secure funding to produce a change in the quantity of housing, which in turn positively influences community vitality. Housing inventory also mediated the effects of total population and percentage population change on community vitality, indicating that housing supply is a fundamental ingredient in community growth strategies. These findings support the conclusion that a combination of housing plans and strategies orchestrated by skilled, committed leadership strengthens rural communities. Heretofore the ling between housing and community vitality has not been investigated; evidence‐based data has been missing from the debate on viable rural community‐development strategies.  相似文献

Changes in gay and bisexual men’s connectedness to the gay community are related to the declining public visibility of HIV/AIDS and greater acceptance for homosexuality and bisexuality in mainstream society. Little work, however, has focused on perceived acceptance for subgroups within the gay community or broader society. Using interviews (n = 20) and a survey (n = 202) of gay and bisexual men in a mid-sized Canadian city, we find perceived hierarchies of acceptance for the various subgroups as well as an age effect wherein middle-aged men perceive the least acceptance for all groups. These differences are linked with the uneven impact of social, political, and institutional changes relevant to gay and bisexual men in Canada.  相似文献

We assessed beliefs about adult children’s responsibilities to financially assist parents and stepparents following later-life divorce and remarriage using a multiple-segment factorial vignette with a national sample (N = 1,121). Ordered logistic regression analyses indicated that beliefs about financial responsibilities to older adults declined after marital transitions, and responsibilities to assist stepparents were more tenuous than to parents. Beliefs about intergenerational responsibilities were affected by adult children’s financial resources and by changes in older adults’ marital statuses. Kinship obligation norms, the adult children’s financial resources, and reciprocity norms were the most common reasons used to explain beliefs about responsibilities to financially assist older parents and stepparents, but these reasons became less salient following divorce and remarriage of the older adult. After marital transitions, beliefs about intergenerational financial responsibilities were more often based on the older adult’s culpability for being in a position of need, relationship quality, and diminished kinship obligations.  相似文献
