Discourse,affect and affliction

While much recent theorizing into affect has challenged the primacy of discourse in understanding social life, this paper is premised on the intertwining of affective experience with discursive meaning. Furthermore, appreciating the entwining of affect and discourse facilitates broader understanding into the illness experience, medical decision‐making and experiences of healing. Today, the biomedical discourse carries particular affective weight that can saturate experiences of affliction. Cultural understandings of disease similarly shape affect that may emerge in affliction. Social meaning, more specifically stereotypes pertaining to identities, interweave with emotion also in the context of medical practice. The doctor‐patient relationship is an affect‐laden encounter where the entwining of affect with social assumptions carries important, yet poorly understood, repercussions for treatment decisions and for the furthering of health inequalities. Both the elusiveness and the power of affect that unfolds in relation to discursive meaning rest on the way in which affect dwells in and resounds through the body.     

The Progression of Sexual Relationships

The authors examine factors associated with the advancement or dissolution of newly formed sexual relationships. Data from the 2006–2010 National Survey of Family Growth (NSFG) was used to examine women and men aged 18–39 (n = 2,774) whose most recent sexual relationship began within the 12 months before their interview. Results indicate that newly formed sexual relationships are often transitory. By 12 months, only 23% of respondents remained in nonresidential sexual relationships, another 27% were cohabiting with that partner, and half had ended their relationships. Sexual relationships formed before age 25 are significantly more likely to break up than to transition into cohabitation. Indicators of social class disadvantage, such as living with a stepparent, expedited cohabitation, whereas measures of advantage, such as having a college‐educated mother, deterred transitions into shared living. Racial differences also emerge: Blacks were less likely than Whites to transition rapidly into shared living.     

亲子关系与小班幼儿焦虑的关系——以沈阳、辽阳和郑州三个城市幼儿园为例

采用赵婷婷等人修订的《亲子关系调查问卷》和Spence学前儿童焦虑量表,对沈阳市、辽阳市、郑州市三座城市的普通幼儿园344名小班幼儿的亲子关系与其焦虑的关系进行了调查测量研究,主要发现：1）小班幼儿亲子关系发展不存在显著的性别差异；而独生子女和非独生子女在亲子关系中亲密性这一维度上呈显著性差异，即独生子女的得分较高。2）幼儿焦虑中的分离焦虑这一维度存在着显著的性别差异，即女孩得分显著高于男孩；独生子女与非独生子女在强迫冲动障碍这一维度上呈显著性差异，即独生子女得分较高。3）亲子关系中要求性、反应性和亲密性因子与幼儿焦虑总分呈显著相关，其亲密性对幼儿焦虑有极其显著的正向预测作用。     

Agreements About Extra-Dyadic Sex in Gay Men's Relationships: Exploring Differences in Relationship Quality by Agreement Type and Rule-Breaking Behavior

Research comparing the quality of monogamous and non-monogamous (“open”) relationships among gay men has produced mixed findings. In addition, little is known about the consequences of breaking the rules of relationship agreements about extra-dyadic sex. Results from a survey of 229 gay men in romantic relationships showed that open relationships were less passionate, but no less intimate or committed, than monogamous or “threesome-only” relationships. However, men who broke rules reported lower relationship quality overall, regardless of the relationship agreement. Thus, it is less the nature of the agreement itself than adhering to the conditions of it that influences relationship quality.     

Relationship Churning and Parenting Stress Among Mothers and Fathers

Researchers have documented the consequences of relationship instability for parenting stress but have given little attention to within‐partner relationship instability. In this study, the authors used data from the Fragile Families and Child Wellbeing Study (N = 3,544) to estimate the association between within‐partner relationship instability (known as churning or on‐again/off‐again relationships) and parenting stress. First, they found that by the focal child's 5th birthday about 16% of biological parents experience churning. Second, compared to being stably together with or stably separated from the child's other parent, churning is associated with greater parenting stress for both mothers and fathers. Because parenting stress is the same or higher among churners compared to their counterparts who stably separate, this suggests that, more than a change in partner, relationship instability—whether within or across relationships—is tied to parenting stress.     

Performative family: homosexuality,marriage and intergenerational dynamics in China

Using in‐depth interview data on nominal marriages – legal marriages between a gay man and a lesbian to give the appearance of heterosexuality – this paper develops the concept of performative family to explain the processes through which parents and their adult children negotiate and resolve disagreements in relation to marriage decisions in post‐socialist China. We identify three mechanisms – network pressure, a revised discourse of filial piety and resource leverage – through which parents influence their gay offspring's decision to turn to nominal marriage. We also delineate six strategies, namely minimizing network participation, changing expectations, making partial concessions, drawing the line, delaying decisions and ending the marriage, by which gay people in nominal marriages attempt to meet parental expectations while simultaneously retaining a degree of autonomy. Through these interactions, we argue that Chinese parents and their gay adult children implicitly and explicitly collaborate to perform family, emphasizing the importance of formally meeting society's expectations about marriage rather than substantively yielding to its demands. We also argue that the performative family is a pragmatic response to the tension between the persistent centrality of family and marriage and the rising tide of individualism in post‐socialist China. We believe that our findings highlight the specific predicament of homosexual people. They also shed light on the more general dynamics of intergenerational negotiation because there is evidence that the mechanisms used by parents to exert influence may well be similar between gay and non‐gay people.     

Is High Sexual Desire a Risk for Women’s Relationship and Sexual Well-Being?

Historically, women’s sexual desire has been deemed socially problematic. The growing popularity of the concept of hypersexuality—which lists high sexual desire among its core components—poses a risk of re-pathologizing female sexual desire. Data from a 2014 online survey of 2,599 Croatian women aged 18–60 years was used to examine whether high sexual desire is detrimental to women’s relationship and sexual well-being. Based on the highest scores on an indicator of sexual desire, 178 women were classified in the high sexual desire (HSD) group; women who scored higher than one standard deviation above the Hypersexual Disorder Screening Inventory mean were categorized in the hypersexuality (HYP) group (n = 239). Fifty-seven women met the classification criteria for both groups (HYP&HSD). Compared to other groups, the HSD was the most sexually active group. Compared to controls, the HYP and HYP&HSD groups—but not the HSD group—reported significantly more negative consequences associated with their sexuality. Compared to the HYP group, women with HSD reported better sexual function, higher sexual satisfaction, and lower odds of negative behavioral consequences. The findings suggest that, at least among women, hypersexuality should not be conflated with high sexual desire and frequent sexual activity.
