Beyond Similarities: Cross-Gender and Cross-Orientation Best Friendship in a Sample of Sexual Minority and Heterosexual Young Adults

The research investigates differences between heterosexual (n?=?714) and lesbian and gay men (n?=?386) young adults regarding best friendship patterns, well-being, and social anxiety. Based on data from a paper-pencil survey of 1,100 Italian young adults aged 18 to 26, this study underlines the importance of the best friend in young adults’ psychological adjustment, highlighting patterns of friendship in heterosexual and lesbian and gay men young adults. Overall, the majority of participants declared that they had best friends; in the total sample, significant differences were found between women and men, and between lesbian/gay men participants and heterosexual young adults. Lesbian and gay men participants reported more cross-gender best friendships than heterosexual participants did, as well as more cross-orientation best friendships. Gender differences were found only with regards to cross-gender friendships: gay men reported more cross-gender friendships than lesbians did, while heterosexual females reported a higher percentage of cross-gender best friendship than heterosexual males did. MANOVA analysis, only in the gay and lesbian sample, showed the effect of gender, cross-gender, and cross-orientation on well-being and social anxiety. For the well-being dimension, gay men participants with female best friends reported higher scores. In terms of social anxiety, lesbian and gay young adults with cross-gender and cross-orientation best friends reported lower levels of social anxiety.     

Domestic horses (<Emphasis Type="Italic">Equus ferus caballus</Emphasis>) fail to intuitively reason about object properties like solidity and weight

From early infancy, humans reason about the external world in terms of identifiable, solid, cohesive objects persisting in space and time. This is one of the most fundamental human skills, which may be part of our innate conception of object properties. Although object permanence has been extensively studied across a variety of taxa, little is known about how non-human animals reason about other object properties. In this study, we therefore tested how domestic horses (Equus ferus caballus) intuitively reason about object properties like solidity and height, to locate hidden food. Horses were allowed to look for a food reward behind two opaque screens, only one of which had either the proper height or inclination to hide food rewards. Our results suggest that horses could not intuitively reason about physical object properties, but rather learned to select the screen with the proper height or inclination from the second set of 5 trials.     

“Doubly Mother”: Heterologous Artificial Insemination Between Biological and Social Parenthood: A Single Case Study

In heterologous artificial insemination, the donation of gametes (either sperm or eggs) from a third person allows infertile and same-sex couples to become parents. Therefore, the child is genetically related to one parent, while the other parent is referred to as the social mother or father. This current single case study aimed at investigating this double access to parenthood in a lesbian couple who had two children after heterologous artificial insemination. In this couple, both women delivered one of the two children, so that each partner is either biological or social mother. The Clinical Generational Interview was used to assess the quality of family relationships, with a specific focus on three dimensions: the origins of each partner, the constitution of the couple, and the generational passage. Paper and pencil textual analysis was conducted following the principles of Interpretative Phenomenological Analysis and led to the identification of six dominant themes (and subthemes): (a) relationship with the family of origin; (b) couple relationship; (c) generational passage; (d) heterologous artificial insemination and “double motherhood”; (e) donor/biological father; and (f) children identity and the disclosure of their origin. This study’s findings revealed the importance of using research techniques aimed at in-depth exploration of this phenomenon consistently with the specificities of the new filiation forms. The adoption of a transgenerational perspective allows articulating conception coordinates with the history of the couple and each partner’s origins.     

Evaluating Fund Performance by Compromise Programming with Linear‐Quadratic Composite Metric: An Actual Case on The CaixaBank in Spain

This paper proposes an additive measure on the basis of compromise programming to evaluate fund performance from multiple criteria, of which the most usual are profitability and risk. This proposal is motivated by the fact that compromise programming is a sound decision support model to obtain scores of alternatives by minimizing weighted distances to an ideal point, the weights reflecting the investor's preferences for the criteria. To define the distance objective function, the linear‐quadratic composite metric is used, which combines advantages of linear and non‐linear objective functions. A critical advantage of compromise programming for fund performance evaluation is that the model can be extended to more than two financial criteria while other measures currently used (either ratio‐based or leverage‐based measures) only consider two criteria, say, profitability and risk. In the application, three investor's profiles are defined, which involve different weighting systems and lead to different fund rankings. These rankings are compared with domination relationships, the latter formulating if a fund is dominated or non‐dominated by convex combinations of other funds. Numerical tables are provided with data, computational process and results, which are analysed. Copyright © 2012 John Wiley & Sons, Ltd.     

“This passage can also be read differently …?:” How Jews and Christians censored Hebrew texts in early modern Modena

This article focuses on the impact exerted by the promulgation of the Index of Prohibited Books by Clement VIII in 1596 on the Jews in early modern Modena. In order to explore diverse cultural perspectives among Jews and Christians, it considers how they read, interpreted, and censored controversial passages in the commentary of Rashi (Solomon ben Isaac of Troyes, 1040–1105) on the Pentateuch. It shows parallels between censorship and the expurgation of Hebrew books, as well as the physical ghettoization and expulsion of Jews from Italian cities enacted by Church authorities, on the one hand, and political and cultural negotiations conducted by the Jews themselves, on the other. Just as the city could be protected from Jewish pollution only through the segregation and expulsion of Jews, so too could the Catholic community be effectively shielded from the contamination of Jewish blasphemies only through banning the Talmud and expurgating other Jewish texts. At the same time, Jews developed means of self-vindication, including a straightforward defense of the principal tenets of Judaism and a stratagem of avoiding discussions that referred to the superiority of Jews over Christians in some interpretations of Rashi. These methods enabled Jews to engage in social and political negotiations with Church and ducal institutions.
