The Impact of Body Dissatisfaction on Distressing Sexual Difficulties Among Men and Women: the Mediator Role of Cognitive Distraction

Research has demonstrated a negative impact of cognitive distraction on sexual activity, and body dissatisfaction has been associated with less satisfying and fewer sexual activities. In the current study we examined the extent to which cognitive distraction, based on body appearance and sexual performance, mediated the impact of body dissatisfaction on sexual difficulties among women and men. A sample of 493 women (M_age = 30.61) and 595 men (M_age = 37.90) completed an online survey. Women reported significantly higher levels of distressing sexual difficulties, significantly more body dissatisfaction, and greater cognitive distraction based on appearance than men. In contrast, men reported higher cognitive distraction based on performance than women. A path analysis model indicated that, for men, only cognitive distraction based on performance mediated the effects of body dissatisfaction on distressing sexual difficulties, and the mediation was only partial as body dissatisfaction had a significant direct effect on distressing sexual difficulties. In contrast, among women, both appearance-based cognitive distraction and performance-based cognitive distraction fully mediated the effects of body dissatisfaction on distressing sexual difficulties.     

The Activation of Incompetence Schemas in Response to Negative Sexual Events in Heterosexual and Lesbian Women: The Moderator Role of Personality Traits and Dysfunctional Sexual Beliefs

Personality traits and dysfunctional sexual beliefs have been described as vulnerability factors for sexual dysfunction in women, and have also been proposed as dispositional variables for the activation of incompetence schemas in response to negative sexual events. However, no study has tested the role of personality traits and dysfunctional sexual beliefs in the activation of incompetence schemas. The current study aimed to assess the moderator role of neuroticism, extraversion, and dysfunctional sexual beliefs in the association between frequency of unsuccessful sexual episodes and activation of incompetence schemas in heterosexual and lesbian women. An online survey was completed by 1,121 women (831 heterosexual; 290 lesbian). Participants completed the NEO Five-Factor Inventory (NEO-FFI), the Sexual Dysfunctional Beliefs Questionnaire—Female Version (SDBQ), and the Questionnaire of Cognitive Schemas Activated in Sexual Context (QCSASC). Findings indicate that neuroticism moderates the association between frequency of negative sexual events and activation of incompetence schemas in heterosexual women. Moreover, several sexual beliefs also act as moderators of the relationship between negative sexual episodes and the activation of cognitive schemas in both heterosexual and lesbian women. Overall, findings support the cognitive-emotional model of sexual dysfunctions, emphasizing the role of personality traits and dysfunctional sexual beliefs as facilitators of the activation of incompetence schemas in response to negative events in women.     

Human Resource Management as a Field of Research*

Drawing on Snow and Thomas's (Journal of Management Studies, 31 (1994), pp. 457–480) matrix, we empirically explore the state of the art in human resource management (HRM) research. The data were obtained through a questionnaire directed to HRM scholars all over the world, in which they were asked about their particular theoretical and methodological approaches. The evidence obtained shows clearly that HRM scholars are progressively abandoning the universalistic perspective and completing their models with contingent and contextual variables. Trying to classify the different contributions proposed and discuss their integration, HRM is described as a field of research with three dimensions: subfunctional, strategic and international. The paper concludes that to provide reliable explanations and valid responses to professional problems, HRM research must advance simultaneously in these three dimensions. As follows from our analysis, there are certain HR issues that still need to be addressed: (1) the strategic use of HR practices, (2) their international applicability, (3) global HR strategies and (4) the synergic integration of HR activities. Nevertheless, to advance our knowledge in these issues, it seems necessary to integrate previous research in subfunctional, strategic and international aspects of HRM.     

Residual variance estimation in moving average models

We consider time series models of the MA (moving average) family, and deal with the estimation of the residual variance. Results are known for maximum likelihood estimates under normality, both for known or unknown mean, in which case the asymptotic biases depend on the number of parameters (including the mean), and do not depend on the values of the parameters. For moment estimates the situation is different, because we find that the asymptotic biases depend on the values of the parameters, and become large as they approach the boundary of the region of invertibility. Our approach is to use Taylor series expansions, and the objective is to obtain asymptotic biases with error of o(l/T), where T is the sample size. Simulation results are presented, and corrections for bias suggested.     

Decision‐Making Factors within Paternity and Parental Leaves: Why Spanish Fathers Take Time Off from Work

This article aims to understand how Spanish fathers construct and justify their decisions to use both paternity and parental leaves. Specifically, we analyse the fathers' discourse about paid work conditions, the couple's decision‐making process, formal and informal care resources, and care and gender equality. We divided responders according to the type of leave that they took and the length of time away from work; as a result, participants in this study were placed into three groups: (1) fathers who take 15 days off from work after childbirth, which are usually those who took only paternity leaves; (2) fathers who take off more than 1 month, which are usually fathers who also took parental leave; and (3) fathers who take off less than 5 days from work, which are fathers who do not take any official leave. We analyse 30 in‐depth interviews with Spanish fathers by applying a critical discourse methodology. The findings indicate that paternity leave is mostly considered a right, but not a duty, and the decision whether or not to use it is viewed as an individual choice. Fathers who take longer leaves judge time off from work not only as an individual right, but also as a duty to their families. These fathers show a low work‐connection discourse, an explicit rejection of other care resources, and a care‐sensitive attitude.     

Determinants of sexual arousal and the accuracy of its self‐estimation in sexually functional males

Men with and without sexual dysfunction present with varying patterns of agreement between subjective estimates of sexual arousal and more objective psychophysiological measures of the same construct. This relative accuracy seems to be associated with sexual function, with men who have sexual dysfunction presenting less accurate estimations (mostly reporting below measured arousal levels). The purpose of this study is to clarify the processes underlying sexual arousal and the accuracy of its self‐estimation. We looked at potential predictors of sexual arousal (subjective and physiological) and accuracy in estimating objective sexual arousal in a sample of 60 sexually functional males. Predictors included pre‐existing sexual attitudes (erotophobia), both trait and state positive and negative affect, self‐focused attention, and interoceptive awareness. Results indicate that this sexually functional sample generally reported below their own erection level. Interestingly, trait negative affect was associated with somewhat lower levels of subjective arousal and higher levels of physiological arousal. On the other hand, state positive affect facilitated both subjective and objective arousal and increased somewhat the accuracy of estimates of erectile responding. Pre‐existing sexual attitudes as well as variations in self‐focused attention and interoceptive awareness evidenced little effect on sexual arousal or the accuracy of its estimation.     

Time-varying autoregressive conditional duration model

The main goal of this work is to generalize the autoregressive conditional duration (ACD) model applied to times between trades to the case of time-varying parameters. The use of wavelets allows that parameters vary through time and makes possible the modeling of non-stationary processes without preliminary data transformations. The time-varying ACD model estimation was done by maximum-likelihood with standard exponential distributed errors. The properties of the estimators were assessed via bootstrap. We present a simulation exercise for a non-stationary process and an empirical application to a real series, namely the TELEMAR stock. Diagnostic and goodness of fit analysis suggest that the time-varying ACD model simultaneously modeled the dependence between durations, intra-day seasonality and volatility.     

Firm-level social returns to education

Do workers benefit from the education of their co-workers? We examine this question first by introducing a model of learning, which argues that educated workers may transfer part of their general skills to uneducated workers, and then by examining detailed matched employer–employee panel data from Portugal. We find evidence of large firm-level social returns (between 14% and 23%), much larger than standard estimates of private returns, and of significant returns accruing to less educated workers but not to their more educated colleagues.
