Parents Differentiate Between Their Personal Values and Their Socialization Values: The Role of Adolescents' Values

This study focuses on the differentiation process, involving the emergence of a distinction between parents' own personal values and their socialization values (the values they want their children to adopt), and on the contribution of children's values to their parents' socialization values. Measures of personal and socialization values were administrated to 603 Israeli adolescents and their parents. As we hypothesized, parents differentiate between their personal values and their socialization values. Moreover, adolescents' values had a specific contribution to their parents' socialization values. These findings provide new support to the notion that the socialization process should be considered as the result of the interaction between parents and their adolescent children rather than as a unidirectional process affected by parents alone.     

Couples’ Sexual Communication and Dimensions of Sexual Function: A Meta-Analysis

Research and clinical data have shown that couples with sexual problems report a lack of sexual communication. However, no published meta-analyses have evaluated the relationship between sexual communication and sexual function. This meta-analysis examines the correlation between couples’ sexual communication and dimension of sexual function across 48 studies. Sexual communication was positively associated with sexual desire (r = .16), sexual arousal (r = .21), lubrication (r = .17), orgasm (r = .23), erectile function (r = .19), less pain (r = .12), and overall sexual function (r = .35). The effect sizes for sexual desire (r = .21; r = .12) and orgasm (r = .26; r = .16) were higher for women than for men. For overall sexual function, studies with married participants (r = .47) had a larger effect size than studies with participants with multiple relationship types (r = .31) or than studies with dating participants (r = .11). Effect sizes were larger for studies conducted outside of the United States (r = .39) compared to studies conducted in the United States (r = .12). We discuss the importance of addressing the relationship between sexual communication and sexual function, as well as future directions for research in this area.     

Castration and Medusa: Orlan's Art on the Cutting Edge

French multimedia artist Orlan (b. 1947) literally altered her body and identity in the name of art by undergoing multiple cosmetic surgeries that replaced her features with those from art historical masterpieces. She transformed herself into an objet d'art as well as a site for public debate, thereby injecting a radical sensibility into Western art and its history. The provocative surgeries at the core of Orlan's “carnal art” both exemplify and expand Freud's notion of castration to include the wish to transcend gender and even the body itself. Like Medusa, Orlan confronts us with blinding images that compel us to question our assumptions about art, beauty, gender, identity, and technology. Her project shows us the fate of human embodiment in a posthuman age. In addition to elucidating her social, feminist, and aesthetic agenda, this paper clarifies her personal psychology and her work's effect on the audience.     

What Does a Man Want? Reflections on “Surrealism Desire Unbound”

This paper is a critical review of the exhibition “Surrealism: Desire Unbound” at the Tate and Metropolitan Museums of Art. The author argues that the majority of the art represents a variety of perverse solutions to male gender anxiety, solutions that most often take the form of viewing the female body as a fetish object or as an object for sadistic drives. She interprets such aggression toward females as being a consequence of the era in which these works were created: Europe between two world wars. Female self-representation is juxtaposed with male-generated art and demonstrates how women artists reclaimed their gaze and desire.     

Infants Show Ratio‐dependent Number Discrimination Regardless of Set Size

Evidence for approximate number system (ANS) representations in infancy is robust but has typically only been found when infants are presented with arrays of four or more elements. In addition, several studies have found that infants fail to discriminate between small numbers when continuous variables such as surface area and contour length are controlled. These findings suggest that under some circumstances, infants fail to recruit either the ANS or object file representations for small sets. Here, we used a numerical change detection paradigm to assess 6‐month‐old infants' ability to represent small values. In Experiment 1, infants were tested with 1 versus 3, 1 versus 2, and 2 versus 3 dots. Infants successfully discriminated 1 versus 3 and 1 versus 2, but failed with 2 versus 3. In Experiment 2, we tested whether infants could compare small and large values with a 2 versus 4 condition. Across both experiments, infants' performance exhibited ratio dependence, the hallmark of the ANS. Our results indicate that infants can attend to the purely numerical attributes of small sets and that the numerical change detection paradigm accesses ANS representations in infancy regardless of set size.     

Social Fathering in Low‐Income,African American Families with Preschool Children

Although research increasingly focuses on nonresident biological fathers, little attention has been given to the role of other men in children's lives. The authors examine the factors associated with social father presence and their influence on preschoolers' development. Findings indicate that the majority of children have a social father and that mother, child, and nonresident biological father characteristics are all related to social father presence. These associations differ depending on whether the social father is the mother's romantic partner or a male relative. The social father's influence on children's development also depends on his relationship to the child. Male relative social fathers are associated with higher levels of children's school readiness, whereas mothers' romantic partner social fathers are associated with lower levels of emotional maturity.     

Evaluating Cooperative Game Theory in water resources

Two empirical applications of Cooperative Game Theory concerned with regional cooperation in the use of irrigation water are presented. Both studies attempt to derive income maximizing solutions for the participants and the related income allocation schemes. Distinction is made between transferable and non-transferable utility situations. The reasonableness and the acceptability of the schemes derived are later critically evaluated. Main findings are: (1) use of utility functions leads to problems in gains allocations, (2) the Core concept may be useless in this application because since it is either difficult to calculate or is empty in many cases, (3) gains allocation and the derived core are heavily dependent on probabilities of coalitions formation in the Shapley value or the Generalized Shapley Value.During the course of this research in The Hebrew University of Jerusalem.On leave from The Hebrew University of Jerusalem.     

Perceptions of the narrative of the ‘other’ among Arab and Jewish adolescents in Israel: between peace talks and violent events

One of the major challenges for the process of peace building is to overcome the rigid structure of the socio‐psychological repertoire that accompanies it. Our longitudinal study examined one element of this repertoire among Jewish and Arab adolescents in Israel: the cognitive legitimacy and the emotional reactions toward the historical narrative of the opponent. We focused our question on the impact of the socio‐political context and the role of the violent reality in the development of these perceptions among youth. Data were collected in four stages (1999–2000, 2002, 2004, and 2007) among various samples of Arab and Jewish high school students (10th and 12th graders). The results showed that among the Jewish adolescents, the readiness to legitimate Palestinian narratives significantly decreased during violent periods. Among the Arab students, the impact of their difficult status as a Palestinian minority in the State of Israel is reflected in their relatively high level of readiness to accept both narratives. The results are discussed from social, cultural, and developmental perspectives with a focus on the role of the conflictual reality itself in the development of the socio‐psychological repertoire among youth.     

Whitewater: Decentralization of river basin water resource management

This paper focuses on empirically assessing determinants of river basin management decentralization, which is growing in popularity among water resource managers world wide. Measuring decentralization as a shift of decision-making responsibility to water users or governments at the river basin level or below, the analysis sheds light on the decentralization reform process and its success, using primary data from 83 river basins world wide. Contrary to common perception that primarily emergency situations trigger reform, persistent water scarcity is found to be a major stimulus to reform. Similarly, financially well-endowed or -developed basins do not necessarily outperform poor and underdeveloped basins. Conditions improving decentralization performance include: existence of dispute resolution mechanisms; greater financial responsibility of users; and as opposed to traditional thinking, government financial support to basin budget.     

Complex Questionnaires

We study a principal–agent model in which the agent is boundedly rational in his ability to understand the principal's decision rule. The principal wishes to elicit an agent's true profile so as to determine whether or not to grant him a certain request. The principal designs a questionnaire and commits himself to accepting certain responses. In designing such a questionnaire, the principal takes into account the bounded rationality of the agent and wishes to reduce the success probability of a dishonest agent who is trying to game the system. It is shown that the principal can construct a sufficiently complex questionnaire that will allow him to respond optimally to agents who tell the truth and at the same time to almost eliminate the probability that a dishonest agent will succeed in cheating.
