“I Want to Feel Like a Full Man”: Conceptualizing Gay,Bisexual, and Heterosexual Men’s Sexual Difficulties

Current understandings of sexual difficulties originate from a model that is based on the study of heterosexual men and women. Most research has focused on sexual difficulties experienced by heterosexual men incapable of engaging in vaginal penetration. To better understand men’s perceptions and experiences of sexual difficulties, seven focus groups and 29 individual interviews were conducted with gay (n = 22), bisexual (n = 5), and heterosexual (n = 25) men. In addition, the extent to which difficulties reported by gay and bisexual men differ from heterosexual men was explored. Data were analyzed using thematic analysis applying an inductive approach. Two intercorrelated conceptualizations were identified: penis function (themes: medicalization, masculine identity, psychological consequences, coping mechanisms) and pain (themes: penile pain, pain during receptive anal sex). For the most part, gay, bisexual, and heterosexual men reported similar sexual difficulties; differences were evident regarding alternative masculinity, penis size competition, and pain during receptive anal sex. The results of this study demonstrate the complexity of men’s sexual difficulties and the important role of sociocultural, interpersonal, and psychological factors. Limitations and suggested directions for future research are outlined.     

Relational Health and Masculine Gender-Role Conflict in the Friendships and Community Relationships of Bisexual,Gay, and Straight Men

This study examined how men's masculine gender-role conflict and the importance men placed on interpersonal relationships in defining their self-identities predicted their relational health experiences in same-sex, dyadic friendships and community relationships. Using an Internet sample of 283 self-identified bisexual, gay, and straight men, results of hierarchical linear regression analyses indicated that for men across sexual orientations, the more importance men placed on interpersonal relationships with other men, the greater the degree of relational health they experienced in dyadic friendships. Additionally, for bisexual and gay men in dyadic friendships with other men, gender-role conflict was inversely related to the relational health of their friendships. In the domain of community relationships, the importance that bisexual and straight men placed on interpersonal relationships in defining their self-identities and levels of gender-role conflict predicted relational health experiences. For gay men, however, feelings of masculine gender-role conflict, alone, predicted poorer relational health in community relationships. Study limitations, clinical implications for practice, and future research directions are discussed.     

Social transformation,collective categories,and identity change

Changes in collective categories of identity are at the core of social transformation. The causal linkages among identity change, institutional change, and change in modes of practice are, however, complex. Developing and adapting ideas from Pierre Bourdieu's work, this article shows the coexistence in tension of a plurality of elements within each collective identity category. On this basis, it proposes a typology of responses at the level of identity to socio-political change. This allows an explanation of patterns of identity change in terms of wider social processes and resource distribution, while remaining open to the sense and complexity of the individual's experience and the moments of intentionality that arise when individuals face choices as to the direction of change. The worth of the model is shown by analysis of modes of identity change in a society now experiencing radical change in socio-political structures, namely post-1998 Northern Ireland.     

A Methodology to Select a Wire Insulation for Use in Habitable Spacecraft

This paper investigates electrical overheating events aboard a habitable spacecraft. The wire insulation involved in these failures plays a major role in the entire event scenario from threat development to detection and damage assessment. Ideally, if models of wire overheating events in microgravity existed, the various wire insulations under consideration could be quantitatively compared. However, these models do not exist. In this paper, a methodology is developed that can be used to select a wire insulation that is best suited for use in a habitable spacecraft. The results of this study show that, based upon the Analytic Hierarchy Process and simplifying assumptions, the criteria selected, and data used in the analysis, Tefzel is better than Teflon for use in a habitable spacecraft.     

Influence of human population size and the built environment on avian assemblages in urban green spaces

While studies of how habitat patch dynamics structures avian communities in urban environments has received some attention, there is considerably less known of how the built environment and human population size may influence the structuring of urban bird communities. We investigated bird populations in Pittsburgh, Pennsylvania (U.S.A.) through replicated point count surveys of breeding birds in 50 parks and cemeteries of varying sizes. We counted 4,435 individual birds in 441 counts. Of the 61 species detected, 27 were rare (detected at <8 points). Migratory species accounted for 46.1 % of all individuals, while 23.2 % of all individuals were of introduced species. Species richness increased significantly with green area size, as did the number of rare species. Species diversity decreased significantly with an increase in the proportion of individuals of introduced species; in particular, cavity nesters were less abundant when introduced species were present. Elements of the built urban environment including commercial development and transportation corridors were associated with significant reductions in park-wide species richness, mean number of species per point, and mean number of individual birds recorded per point. Human population size was positively related to increased numbers of individuals of introduced species, but a lower mean number of species per point. Ours is among the first to identify specific relationships between avian population characteristics and human population size, as few other studies have specifically incorporated human population size into a local, fine grain study design. Our data suggest that human population size is an important parameter that can be measured independently of characteristics of the built environment and the physical characteristics of the park itself as a correlate of avian diversity and abundance. Our study points to a variety of trade-offs needed to manage habitat for birds in urban settings.     

Do women who choose to become surrogate mothers have different psychological profiles compared to a normative female sample?

BackgroundSurrogate mothers are routinely assessed for their suitability to function in the role of surrogacy. Such assessments often include psychological testing including the Minnesota Multiphasic Personality Inventory-Revised (MMPI-2). There has been a paucity of research detailing the personality structures of these women, especially with the MMPI-2.Research objectiveThe current study examined the validity and clinical profiles of surrogate mothers (N = 43) compared to a non-patient, normative reference sample of women (N = 40) using their MMPI-2 results.MethodThis study examined between group differences among the 68 scales of the MMPI-2. Independent-sample t-tests were conducted for each of the scales, with those violating homogeneity of variance assessed with a non-parametric, Mann–Whitney U test.FindingsThe findings demonstrated that surrogate mothers produce profiles with lower values than normative samples across several MMPI-2 scales. For this unique group, elevations were observed on scales that assess profile validity, views on traditional gender roles, repression, ego strength, social obligation and duties, and contained hostility, relative to the normative group.ConclusionThe findings provide an initial examination of the profiles of surrogate mothers on the MMPI-2. The findings revealed that the psychological suitability of surrogate mother candidates appear to be a composite of being both tough-minded and sensitive, sufficiently resilient to manage the role of surrogacy, and aware of the importance of emotional boundary-setting related to pre-natal attachment.     

Boundary Objects Revisited: A Comparative Analysis of World Making in Avant-Garde Fashion Design and Animal Husbandry

Drawing on Susan Leigh Star’s conceptualization of boundary objects as a corpus of actions through which an imaginary context for doing social work emerges, this article examines how two seemingly disparate sites of cultural production can be comparatively brought into conversation with one another. These sites include specific expert communities where actors within the fields of fashion design and livestock husbandry both evaluate and theorize new social possibilities. By attending to how these practices unfold through an experimental rendering of expertise this article employs the notion of a boundary object to comparatively analyzing the speculative practices of these two sites.
