The contested definitions of “swinging” and “polyamory” reveal profound inconsistencies in the logics of sex, love, commitment, and coupledom. In this article, I use a number of non-monogamy blogs and online glossaries as examples of the way these two words are often deployed against each other in an effort to position the speaker in relation to mononormative practices of sex and love. Leaving aside questions of the accuracy of particular definitions, I map a range of definitions against two existing scholarly/activist tools for describing relationship styles, specifically Gayle Rubin’s “Charmed Circle” and Meg-John Barker’s sex/love continuums. This exercise is doubly fruitful: first, the tools reveal the political stakes of the definitional debates; second, the definitions demonstrate that the distinctions we commonly use to distinguish between types of relationships—including types of non-monogamous relationships—in fact rely on mononormative assumptions about sex, love, and friendship. If “mononormativity” is defined as the system of ideas, institutions, and practical orientations that provide the backdrop against which the idea of monogamy as coherent, common, natural, and right congeals, the sex/love skirmishes of “swinging” and “polyamory” remind us that its logics are both pervasive and deeply fractured.  相似文献

Despite increasing empirical support for an integrated approach to treating trauma and substance abuse, many substance abuse treatment programs have been slow to embrace integrated models of practice. Using an embedded case study design, the purpose of this study was to understand barriers that prevented a substance abuse treatment provider and 20 professionals and staff from adopting an integrated approach to treating substance abuse and trauma. Data analysis revealed 2 kinds of barriers that prevented substance abuse treatment professionals from fully integrating substance abuse and trauma: systemic and professional barriers. These barriers have to be taken into account when trying to move providers and professionals toward integrated approaches to treating substance abuse and trauma.  相似文献

Despite a re-evaluation of risks in recent years, hormone replacement therapy is still surrounded by controversy. Almost 30% of women in a recent survey sought a natural approach to combat climacteric symptoms. Nevertheless, a large proportion of patients felt that they wanted a good safety profile and strong evidence base for treatment. This article seeks to review the evidence supporting non-hormonal approaches to treatment. There is only conflicting evidence at best to support alpha-2 agonists, e.g. clonidine and limited evidence for dihydroepiandrosterone and natural progesterones. There is limited randomized controlled trial data for gabapentin, selective norepinephrine re-uptake inhibitors (SNRIs) and selective serotonin re-uptake inhibitors (SSRIs), many of these studies being related to breast cancer patients. Of the herbal medicinal products, the largest evidence base rests with phytoestrogens. A Cochrane Database review looking at all types of phytoestrogens, e.g. red clover extracts, dietary soya and soya extracts concluded that there was no evidence to support improvement in climacteric symptoms and the meta-analysis of a 178 studies on soy products was inconsistent. Nevertheless, other studies disagree. Mammographic density is not affected by soy or phytoestrogen products and recent in vitro work shows only a weakly proliferative effect of soy isoflavone on breast cancer cells and evidence that soy isoflavone blocks the proliferative effect of estradiol on these cells. There are no studies looking at clinical outcome measures for cardiovascular disease but a number of studies looking at biochemical markers including arterial wall stiffness and apolipo protein B. Recent studies have also looked at the effects of red clover isoflavone on mood and depression, using specific depression rating scales. Finally, it is important to note that herbal medicinal products should not be used without caution. Some may produce quite marked side-effects in high doses and others can interact with pre-existing medication. A strategy for which patients are suitable for herbal medicinal products is reviewed.  相似文献

Homeless youth lack the traditional support networks of their housed peers, which increases their risk for poor health outcomes. Using a multilevel dyadic analytic approach, this study identified characteristics of social contacts, relationships, and social networks associated with the provision of tangible and emotional support to homeless youth (= 419, M age = 20.09, SD = 2.80). Support providers were likely to be family members, sex partners, or non–street‐based contacts. The provision of support was also associated with contacts' employment and homelessness status, frequency of contact, shared risk behaviors, and the number of network members that were homeless and employed. The results provide insights into how homeless youth could be assisted to develop more supportive social networks.  相似文献

This study investigated the risk factors associated with the occurrence of child physical and psychological abuse in South Korea based on the ecological theory of child maltreatment. A subsample of 3‐ to 18‐year‐old children from “A Study on the Current State of Child Abuse and Neglect,” a nationally representative study on child abuse and neglect, was utilized for secondary data analysis. The sample was divided into two age groups (third graders in elementary school and below and fourth graders and above). We utilized hierarchical logistic regression for each age group separately to analyze the data. The variables at each level of the system (i.e., ontogenic development, microsystem, and exosystem) were entered into the model in sequential order. The results showed the common risk factors for both age groups are the caregiver's experience of abuse in childhood, the child's problem behavior, exposure to domestic violence, community size, and informal social control. The child's age was also significant in both groups but in the opposite direction. Social support was a significant predictor for the younger age group only, while the caregiver's level of education was significant for the older age group only. Implications for future research and practice are discussed based on the study results.  相似文献

In an attempt to determine if a community standard existed and to relate judgments of pornography to conservatism, scores on Wilson and Patterson's Conservatism Scale, yes‐no judgments on whether 25 pictures were or were not pornographic, and demographic data were obtained from a random sample (N = 114) of a community. Results were as follows: (1) suggestive evidence for the existence of a community standard; (2) the c‐scale correlated .57 (N = 114, p < .01) with number of pictures judged pornographic; (3) the 25 pictures met Guttman requirements of unidimensionality (reproducibility of .925); and (4) factor analysis of the pornography judgments yielded three clear‐cut factors and one ambiguous factor which were ordered along the Guttman dimension.  相似文献

The semi‐Markov process often provides a better framework than the classical Markov process for the analysis of events with multiple states. The purpose of this paper is twofold. First, we show that in the presence of right censoring, when the right end‐point of the support of the censoring time is strictly less than the right end‐point of the support of the semi‐Markov kernel, the transition probability of the semi‐Markov process is nonidentifiable, and the estimators proposed in the literature are inconsistent in general. We derive the set of all attainable values for the transition probability based on the censored data, and we propose a nonparametric inference procedure for the transition probability using this set. Second, the conventional approach to constructing confidence bands is not applicable for the semi‐Markov kernel and the sojourn time distribution. We propose new perturbation resampling methods to construct these confidence bands. Different weights and transformations are explored in the construction. We use simulation to examine our proposals and illustrate them with hospitalization data from a recent cancer survivor study.
