How do my parents react when I feel happy? Longitudinal associations with adolescent depressive symptoms,anhedonia, and positive affect regulation

Parental emotion socialization plays a role in the development of adolescents’ emotion regulation and is associated with adolescents’ depressive symptoms. Most research has focused on parental socialization of negative affect. The scarce research on parental socialization of positive affect (PA) shows that parental downgrading responses to adolescents’ PA are associated with concurrent adolescent depression. The aims of the present study were to examine longitudinal associations of both maternal and paternal responses to adolescents’ PA with how adolescents regulate their PA (i.e., dampening and enhancing) and with adolescents’ general depressive symptoms and anhedonia. We also considered associations in the opposite direction from adolescent regulatory responses and symptoms to parental responses. In a two‐wave study (1‐year interval), 635 adolescents from Grade seven completed questionnaires. Cross‐sectionally, maternal and paternal responses to adolescents’ PA were associated with concurrent adolescents’ PA regulation as well as adolescents’ depressive and anhedonic symptoms. Longitudinally, low maternal and paternal enhancing responses to adolescents’ PA predicted relative increases in anhedonic symptoms and relative decreases in adolescent enhancing over time. Low maternal enhancing was also predictive of relative increases in depressive symptoms. The present study points to bidirectionality of relations as adolescents’ level of depressive symptoms predicted maternal and paternal responses.     

Defender–Attacker Decision Tree Analysis to Combat Terrorism

We propose a methodology, called defender–attacker decision tree analysis, to evaluate defensive actions against terrorist attacks in a dynamic and hostile environment. Like most game‐theoretic formulations of this problem, we assume that the defenders act rationally by maximizing their expected utility or minimizing their expected costs. However, we do not assume that attackers maximize their expected utilities. Instead, we encode the defender's limited knowledge about the attacker's motivations and capabilities as a conditional probability distribution over the attacker's decisions. We apply this methodology to the problem of defending against possible terrorist attacks on commercial airplanes, using one of three weapons: infrared‐guided MANPADS (man‐portable air defense systems), laser‐guided MANPADS, or visually targeted RPGs (rocket propelled grenades). We also evaluate three countermeasures against these weapons: DIRCMs (directional infrared countermeasures), perimeter control around the airport, and hardening airplanes. The model includes deterrence effects, the effectiveness of the countermeasures, and the substitution of weapons and targets once a specific countermeasure is selected. It also includes a second stage of defensive decisions after an attack occurs. Key findings are: (1) due to the high cost of the countermeasures, not implementing countermeasures is the preferred defensive alternative for a large range of parameters; (2) if the probability of an attack and the associated consequences are large, a combination of DIRCMs and ground perimeter control are preferred over any single countermeasure.     

Matching in sexual experience for married, cohabitating, and dating couples

The present study examined heterosexual romantic partners' number of intercourse partners prior to the initiation of their relationship to determine if a significant positive correlation (matching) occurred between partners, and if this matching was associated with their level of love, satisfaction with, and commitment to the relationship. One hundred and six couples who were dating, cohabitating, or married participated in this study. Results indicated that, with the exception of cohabitating couples, romantic partners showed a significant level of matching in the prior number of intercourse partners. Further, among the married couples, a higher discrepancy between men's and women's number of previous intercourse partners was related to lower levels of love, satisfaction, and commitment in the relationship.     

Mainstreaming kink: the politics of BDSM representation in U.S. popular media

This article explores nonpractitioners' understandings of and responses to the increasingly mainstream representation of BDSM in U.S. media, focusing on the film Secretary (Shainberg, 2002). Survey, focus group, and interview data indicate that popular images of SM promote the acceptance and understanding of sexual minorities through two mechanisms: acceptance via normalization, and understanding via pathologizing. Rather than challenging the privileged status of normative sexuality, these mechanisms reinforce boundaries between protected/privileged and policed/pathological sexualities. Instead of celebrating increased representation, this article argues that political energy might be directed toward the desire that the popularity of BDSM representations signifies: the desire to encounter authentic, undisciplined, and noncommodified representations that would transgress the sexual norms of American postmodern consumer culture.     

Ergonomic adequacy of the baby nursery of child development center located in UFSC - Florianópolis

A study in the educators' work station at baby nursery of NDI/UFSC, located in Florianópolis, was conducted using the Work Ergonomic Analysis methodological tool. The demand considered was the educators' physical exhaustion caused by the weight carried when taking care of the babies, the postures assumed during the labor activity and the spatial arrangement of the baby nursery. Thinking ergonomically, the spatial arrangement is directly associated to three factors: the formal aspect of the environment, the esthetic aspect including colors and finish quality and the ease of understanding involved in the baby nursery labor. By the ergonomic adequacy it is possible to assert that if were established better conditions of posture and comfort for the educators, as well as satisfactory technical and operational information to carry out the activities, greater safety and welfare would be provided to the babies, the main focus of the work.     

Capital Structure of Nongovernmental Development Organizations

In the first international study of this kind, we analyze the capital structure of 364 nongovernmental development organizations (NGDOs) from three different countries: Belgium, Spain, and the United Kingdom. We observe lower debt ratio values in the United Kingdom, and significant differences between countries were found by testing an econometric model with the five classical determinants of leverage, considering total debt and both long‐ and short‐term debt. We find support for the pecking order theory, and we broadly discuss some possible reasons for the obtained differences.
