A skew extension of the slash distribution via beta-normal distribution

In this work we introduce a generalization of the slash distribution using beta-normal distribution. This newly defined generalization is more flexible than the ordinary slash distribution and contains distributions that can be not only symmetric and unimodal, but also asymmetric and bimodal. We study the properties of the new generalized distribution and demonstrate its use on some real data sets considering maximum likelihood estimation procedure.     

Asymptotic and Bootstrap Inference for AR(∞) Processes with Conditional Heteroskedasticity

The main contribution of this paper is a proof of the asymptotic validity of the application of the bootstrap to AR(∞) processes with unmodelled conditional heteroskedasticity. We first derive the asymptotic properties of the least-squares estimator of the autoregressive sieve parameters when the data are generated by a stationary linear process with martingale difference errors that are possibly subject to conditional heteroskedasticity of unknown form. These results are then used in establishing that a suitably constructed bootstrap estimator will have the same limit distribution as the least-squares estimator. Our results provide theoretical justification for the use of either the conventional asymptotic approximation based on robust standard errors or the bootstrap approximation of the distribution of autoregressive parameters. A simulation study suggests that the bootstrap approach tends to be more accurate in small samples.     

An Ex-Post View of Inequality of Opportunity in France and its Regions

This paper proposes an ex-post measure of inequality of opportunity in France and its regions by assessing the inequality between individuals exerting the same effort. To this end, we define a fair income that fulfils ex-post equality of opportunity requirements. Unfairness is measured by an unfair Gini based on the distance between the actual income and the fair income. Our findings reveal that the measures of ex-post inequality of opportunity largely vary across regions, and that this is due to differences in reward schemes and in the impact of the non responsibility factors of income. We find that most regions have actual incomes closer to fair incomes than to average income, excepted Ile de France where the actual income looks poorly related to effort variables. Finally, we find that income inequality and inequality of opportunity are positively correlated among regions.     

Validity evidence of the Portuguese adaptation of the Ambivalent Sexism Inventory / Evidencias de validez de la adaptación portuguesa de la Escala de Sexismo Ambivalente

Abstract

Modern forms of sexism have promoted the development of new scales and evaluation tools. The Ambivalent Sexism Inventory (ASI) (Glick & Fiske, 1996) aims to assess sexism along two dimensions: hostile sexism and benevolent sexism. The aim of this study is to present evidence of the validity of the factor structure of the Portuguese version of the ASI by analysing its structure and its relationships with neosexism and social dominance. The sample consisted of 446 Portuguese participants (68.6% female) between 17 and 77 years old. Results confirmed the two-factor structure; however, the best fit was registered with a four-factor structure: one hostile factor and three benevolent factors. Both hostile and benevolent sexism were correlated with neosexism and social dominance orientation. Future research should explore the dimensionality of the scale based on a four-dimension structure and its relationship to others sexism issues.     

Queering Child and Adolescent Mental Health Services: The Subversion of Heteronormativity in Practice

This article explores the exercise of heterosexist‐infused power relations within a Child and Adolescent Mental Health Services (CAMHS) inpatient unit in the UK. The ways in which heterosexism may wield its power within CAMHS in conjunction with the support of sexism, adultism, classism and sanism are discussed. That is, this article contributes to the understanding and subverting of heteronormativity in practice. With this focus in mind, other forms of intersecting oppressions are detailed to highlight the role they play in both controlling young people and teaching them about the workings of patriarchy and social norms. The aim of the article is to contribute to the disruption of the heteronormativity inherent in the arrangements within CAMHS and the dominant normative practice that produces multiple subjectivities in this setting.     

Difficulties in Diagnosing Sexual Abuse in Children with Condyloma Acuminata in Turkey

Human papillomavirus is responsible for anogenital warts and could be regarded as an indicator of possible sexual abuse in children. A genital wart was detected during an investigation of anti–hepatitis C virus positivity in a four-year-old male patient. No pathological findings of another sexually transmitted disease were found except complete cleft palate and circumferential lesions in the perianal region. No family member was anti-hepatitis C virus positive, but the patient's uncle and his wife had genital condylomata. Although detailed physical examination uncovered no other findings indicative of sexual abuse, suspicion of abuse could not be eliminated. Therefore, we wanted to draw the attention of health professionals to the association of anogenital warts and sexual abuse.

Lottery marketing in Québec and social deprivation: excessive exposure,insufficient protection?

In 2008, the Institut national de santé publique du Québec (INSPQ) undertook a research programme on lotteries. The preliminary qualitative exploratory component enabled us to observe the diversity and ubiquity of lottery advertising to which the vast majority of the population is exposed, including minors and non-players. The aim of a second component was to better comprehend the relationships between exposure to lottery marketing, lottery purchasing habits, attitudes towards gambling, and socio-economic vulnerability indicators. The study's data was collected by a polling firm from a representative sample of adults in the Québec population (n = 2001). Our survey revealed significant links between exposure, gambling behaviour and certain socio-economic indicators: for example, individuals with lower levels of education more often play the lotteries and spend the most on them. In addition, a greater number of people who are less educated and from a low-income household considered that lottery advertising was very or excessively present in their daily lives and that the amount of advertising has increased in recent years. From the perspective of creating healthy environments and protecting vulnerable populations, legislative measures to control the quantity, location and contents of gambling marketing would be promising preventive measures.     

Book Reviews

In censuses and surveys in most African countries it has become the practice to estimate informants' age by the method of the historical calendar. This involves an attempt to relate a remembered historical event, occurring during the subject's childhood, with his age at the time.

This paper attempts a first evaluation of the method with particular reference to the 1961–63 multi-round survey in rural Morocco. It is shown that in practice the method is highly complex and easily misunderstood by interviewers and respondents. An attempt to lay down a precise procedure by means of a very detailed questionnaire appeared to yield at best only marginally more accurate results than the simpler procedure used in an earlier round. The more complex questionnaire did, however, introduce new patterns of misuse by the interviewer. There was evidence that the historical calendar gave somewhat better data than eye estimates, but results were highly defective for both methods.

It is clear that the method is far from perfect. Interviewer training and supervision remain the key to accurate age determination. If the potential benefits of the complex historical calendar method are to be realized, training and supervision need to be even more thorough than where simpler methods are used.
