Reliability,Validity and Classification Accuracy of the South Oaks Gambling Screen in a Brazilian Sample

The purpose of this study was to examine the reliability, validity and classification accuracy of the South Oaks Gambling Screen (SOGS) in a sample of the Brazilian population. Participants in this study were drawn from three sources: 71 men and women from the general population interviewed at a metropolitan train station; 116 men and women encountered at a bingo venue; and 54 men and women undergoing treatment for gambling. The SOGS and a DSM-IV-based instrument were applied by trained researchers. The internal consistency of the SOGS was 0.75 according to the Cronbach’s alpha model, and construct validity was good. A significant difference among groups was demonstrated by ANOVA (F _(2.238) = 221.3, P < 0.001). The SOGS items and DSM-IV symptoms were highly correlated (r = 0.854, P < 0.01). The SOGS also presented satisfactory psychometric properties: sensitivity (100), specificity (74.7), positive predictive rate (60.7), negative predictive rate (100) and misclassification rate (0.18). However, a cut-off score of eight improved classification accuracy and reduced the rate of false positives: sensitivity (95.4), specificity (89.8), positive predictive rate (78.5), negative predictive rate (98) and misclassification rate (0.09). Thus, the SOGS was found to be reliable and valid in the Brazilian population.     

Preparing for Male Condom Use: The Importance of Volitional Predictors

Objectives: Intention is not sufficient to actually use condoms, as self-regulatory processes are needed to translate motivation into action. This study has focused on the role of preparatory behaviors as a proximal predictor of condom use and examined how they contribute to the self-regulatory processes proposed by the health action process approach model. Methods: An on-screen longitudinal study was conducted with 3 measurement points 2 weeks apart. The participants were young men aged 18 to 25 years old (N = 203) recruited from vocational training centers. Outcome expectancies, perceived self-efficacy, intention, action planning, coping planning, volitional self-efficacy, preparatory behaviors, and condom use were assessed by self-report. A structural equation analysis was used to test a series of 3 nested models, with all parameters estimated by bootstrapping. Results: The model proposed that the included preparatory behaviors provided the best fit to the data. Preparatory behaviors were the most proximal predictors of condom use, and mediation occurred in a sequential manner with preparatory behaviors preceding the volitional variables, action and coping planning, and volitional self-efficacy. Conclusions: To bridge the intention–behavior gap, preparatory behaviors play a mediating role, demonstrating how they work in conjunction with other volitional variables such as planning and self-efficacy in the translation of behavioral intentions into actual condom use.     

Using occupational structure to measure employability with an application to the Brazilian labor market

We propose measuring individual employability as a weighted average across occupations of a worker’s predicted wage for each occupation. Weights are given by the individual occupational probability distribution. Under this measure, a worker is more employable than another if she has a greater chance to obtain a better paid occupation. After normalization, expected employability corresponds to the population correlation between occupational predicted wages and the chance to obtain employment in these occupations and serves as a measure of the allocative efficiency of labor market. We apply the methodology to Brazil and found that employability increased and became less unequally distributed from 2002 to 2011. We used a decomposition method to investigate the causes of these changes. Although average normalized employability is weakly positive, it has increased for the period, which suggests that there is room for efficiency gains in the allocation of workers to occupations in the Brazilian labor market.     

A Euclidean Likelihood Estimator for Bivariate Tail Dependence

The spectral measure plays a key role in the statistical modeling of multivariate extremes. Estimation of the spectral measure is a complex issue, given the need to obey a certain moment condition. We propose a Euclidean likelihood-based estimator for the spectral measure which is simple and explicitly defined, with its expression being free of Lagrange multipliers. Our estimator is shown to have the same limit distribution as the maximum empirical likelihood estimator of Einmahl and Segers (2009 Einmahl , J. H. J. , Segers , J. ( 2009 ). Maximum empirical likelihood estimation of the spectral measure of an extreme-value distribution . Ann. Statist. 37 ( 5B ): 2953 – 2989 .[Crossref], [Web of Science ®] , [Google Scholar]). Numerical experiments suggest an overall good performance and identical behavior to the maximum empirical likelihood estimator. We illustrate the method in an extreme temperature data analysis.     

Children's perceptions of playfighting, playchasing and real fighting: a cross-national interview study

Playfighting and chasing can he distinguished from real fighting, hut their significance in children's development remains uncertain. This study examines playfighting and chasing from the child's, rather than the observer's, perspective, using a questionnaire given to 8 and 11 year olds in England and South Italy and 5 year olds in England. Findings were generally similar for English and Italian children. Most hoys and girls reported both liking, and taking part in, playchasing; liking and participation in playfighting was more divided, though more so for boys, with many children disliking the perceived risk of injury in playfighting. About half the children (more boys than girls) reported having been in a serious fight, often provoked by verbal abuse or accidental injury. Most children reported that they could tell playfighting from a serious fight; at 5 years, liking and taking part in playfights was a predictor of this ability, which approached ceiling by 8 and 10 years. A wide variety of cues were given which could distinguish playful and serious fighting. Findings were consistent with the practice hypothesis for playfighting. However, most children also thought that playfighting could lead to a serious fight, especially as a result of accidental injury; escalation of this kind was also thought to be more likely if the play partner was not a best friend. Both ‘honest mistakes’ and ‘cheating’ seem to be possible explanations for playfighting leading to serious fighting. Assertion or maintenance of dominance may be a function for cheating in playfighting.     

A review of inflation accounting and its economic implications

The purposes of this paper are firstly to identify the problems which inflation creates in the context of conventional accounting methods, secondly to consider the alternative forms of inflation accounting which have been proposed, thirdly to look in more detail at the particular method which is to be adopted in the UK, and finally to consider the effects which that method will have on company results and on broader economic issues.     

A hierarchical theory of occupational segregation and wage discrimination

Becker's model of discrimination is extended to the case where men exhibit distastes for working under female managers. The distribution of women in the resulting occupational hierarchy depends on the number of women in lower occupations, the wages of male workers in lower occupations, and male distastes for female management. Thus, there exists an occupational sorting function, related to wages, that determines the occupational distribution of women. We integrate this sorting function into a standard wage equation to derive a new decomposition of male-female wage differentials and apply it to a sample of insurance industry workers from the 1988 CPS.     

Post‐Fordist reconfigurations of gender,work and life: theory and practice

Based on an in‐depth study with 56 informants (25 women and 31 men), across the ICT (information and communication technology), creative and academic sectors in one city/regional hub in Ireland, this article investigates the so‐called revolution in work/life practices associated with the post‐Fordist labour processes of the Knowledge Economy from the perspectives of workers themselves. Recent theorizations of post‐Fordist work patterns emphasize a rearranging of work and life place boundaries; a reconfiguring of work and life time boundaries; and a dissolving of the gendered boundaries of work and life (production and social reproduction) (Adkins and Dever 2014 ; Morini and Fumagalli 2010 ; Gill and Pratt 2008 ; Weeks 2007 ; Hardt and Negri 2004 ). Our findings suggest that, instead of dissolving boundaries, workers constantly struggle to draw boundaries between what counts as work and as life, and that this varies primarily in relation to gender and stage in a gendered life trajectory. Work extensification is compensated for via a perceived freedom to shape one's own life, which is articulated in terms of individualized boundary‐drawing. While younger men embraced ‘always on’ work, they also articulated anxieties about how these work habits might interfere with family aspirations. This was also true for younger women who also struggled to make time for life in the present. For mothers, boundary drawing was articulated as a necessity but was framed more in terms of personal choice by fathers. Although all participants distinguished between paid work and life as distinct sites of value, boundaries were individually drawn and resist any easy mapping of masculinity and femininity onto the domains of work and life. Instead, we argue that it is the process of boundary drawing that reveals gendered patterns. The personalized struggles of these relatively privileged middle‐class workers centre on improving the quality of their lives, but raise important questions about the political possibilities within and beyond the world of post‐Fordist labour.     

Psychological Flexibility and Self-Compassion in Gay and Heterosexual Men: How They Relate to Childhood Memories,Shame, and Depressive Symptoms

This study explores differences between men who are gay (n = 53) and men who are heterosexual (n = 52) regarding memories of shame events and of warmth and safeness experiences with parents during childhood and adolescence, self-compassion, psychological flexibility, internal shame, and depression. Also, it aims to explore whether psychological flexibility and self-compassion play a role in the association between these memories and internal shame and depressive symptoms. Results confirmed the mediating role of psychological flexibility and self-compassion. These findings suggest the appropriateness of promoting acceptance and self-compassion towards difficult memories in a therapeutic setting with men who are gay experiencing shame and depressive symptoms.     

Ergonomics and accessibility for people with visual impairment in hotels

This article presents a diagnosis of luxury or superior hotels in the city of Natal, located in the state of Rio Grande do Norte, in northeastern Brazil, in what concerns accessibility to the visually impaired. The main objective is to present the guiding principles to design actions and interventions that must be considered in the preparation or revision of technical standards and manuals of good practice in accessibility related to people with visual impairments who are hotel users. The survey showed that the hotels do not meet the normative indications of accessibility, their facilities are in-accessible (have prevented access) or of reduced accessibility and its employees are not prepared to provide adequate hospital services for people with visual impairment. It was concluded that some of the accessibility problems faced by people with visual impairments are also faced by people in general.
