Attitudes of Heterosexual Men and Women Toward HIV Negative and Positive Gay Men

Attitudes of Italian heterosexual men and women toward gay men, both HIV positive and negative, are poorly investigated. Italian culture is still extremely conservative and provides limited support to the gay community (e.g., lack of same-sex marriage recognition). Consequently, gay men experience social exclusion and disparities. The present study explores the association between homophobia and closeness with sexual orientation and HIV status. 261 heterosexual Italian men and women were assessed for feelings of closeness and homophobia after reading a vignette where the character was C1: heterosexual and HIV negative; C2: gay and HIV negative; or C3: gay and HIV positive. Experiences of homophobia and closeness varied depending on gender of participant and condition assigned, and higher levels of homophobia were correlated with lower levels of closeness regardless of HIV status. Implications and future directions are discussed.     

Physical exercise,nutrition and hormones: three pillars to fight sarcopenia

Background: Sarcopenia is a pathophysiological condition diffused in elderly people; it represents a social issue due to the longer life expectancy and the growing aging population. It affects negatively quality of life and it represents a risk factor for other pathologies, such as diabetes, cardiovascular disease, and obesity. No silver bullet exists to hinder sarcopenia, but it may be counteracted by physical exercise, nutrition, and a proper endocrine milieu. Indeed, we aim to analyze the scientific literature to give to clinician effective advices to counteract sarcopenia.

Main text: Physical exercise, proper nutrition, optimized hormonal homeostasis represent the three pillars to fight sarcopenia. Physical exercise represents the most effective remedy to face sarcopenia, in particular if it is combined with a proper diet and with an adequate endocrine milieu. Consistency in training, adequate daily protein intake and eugonadism seems to be the keys to fight sarcopenia. The combination of these three pillars might act synergistically.

Conclusions: Optimization of these factors may increase their efficiency; however, scientific data may be sometimes confusing so far. Therefore, we aim to give practical advices to clinician to identify and to highlight the most important aspects in each of these three factors that should be addressed.     

A study of search algorithms’ optimization speed

Search algorithms are often compared by the optimization speed achieved on some sets of cost functions. Here some properties of algorithms’ optimization speed are introduced and discussed. In particular, we show that determining whether a set of cost functions F admits a search algorithm having given optimization speed is an NP-complete problem. Further, we derive an explicit formula to calculate the best achievable optimization speed when F is closed under permutation. Finally, we show that the optimization speed achieved by some well-know optimization techniques can be much worse than the best theoretical value, at least on some sets of optimization benchmarks.     

“Phil's Calling Grandma… ”: The Role of External Support in Human–Companion Animal Identity Pairings

This exploratory paper deals with human–animal role identity pairings such as parent–child or sibling–sibling and the necessity of support from other actors both for the formation of these idiosyncratic identities, as well as for their situational placement in social environments not limited to the nonhuman animal. Taken from a qualitative study examining identity formation counter to the nonhuman animal, I use in‐depth interviews of both people with and without human children to demonstrate how human‐to‐human relationships are formed by categorizing the companion animal as a “child” of sorts within the family structure. These relationships prove integral to the continued development and enactment of identities such as the animal “parent” or the animal “sibling” via three different groups: their own parents, partners, and, in one case, adult siblings. This creates positive affect and commitment to the identity across other social situations. Implications of these findings for identity theory and family research are discussed.     

The boomerang effect of psychological interventions

Research has found that teaching people about psychological biases can help counteract biased behavior. On the other hand, due to the innate need for preservation of a positive self-image, it is likely that teaching people about biases they hold, may cause a boomerang effect in cases where being associated with a specific bias implies negative social connotations. In the three studies below we examine situations in which psychological bias implies negatively associated behavior, and show that teaching people about bias in those contexts can be counterproductive.     

Strengthening Clinical Research in Marriage and Family Therapy: Challenges and Multilevel Solutions

There is a critical need for high‐quality and accessible treatments to improve mental health. Yet, there are indications that the research being conducted by contemporary marriage and family therapy (MFT) scholars focuses less on advancing and disseminating clinical interventions than in previous decades. In this article, we describe challenges to increasing rigorous clinical research in MFT. We use systems mapping and the intervention‐level framework to identify strategic goals designed to drive innovation in clinical research in the field. It is our hope this article encourages dialog and action among MFT stakeholder groups to support clinical science that will improve the health and functioning of families.     

Addressing inequality: Educators responding to the contexts of young children’s lives?

A child's early relationships and experiences influence their long-term development and learning. In Australia, some children can face complex levels of deprivation when compared to their peers. This study sheds light on how educators are responding. Data analysed consist of individual interviews with early childhood educators working in diverse communities. The findings highlight educators’ accounts of responsiveness as narrowly framed with attention focused on children's cultural heritage which overshadows other equity groups. The paper argues that by becoming sensitive to the contexts of children's lives, there is potential to build the early childhood workforce's capacity for addressing inequalities in childhood.
