Romaphobia and the media: mechanisms of power and the politics of representations

ABSTRACT

This special issue of Identities, entitled ‘Romaphobia and the media’, examines entrenched and ongoing media coverage of Roma, Gypsy and Traveller people across Europe. The focus is on how the media problematises the Roma, how it constructs a ‘conceptual map’ about Roma people and what this tells us about the societies we live in. This special issue includes five academic articles all examining the constructions and stereotypes used in the media in various formats and European countries. After these academic articles, this special issue then deviates from the normal journal structure by including three commentary pieces from professionals from varying Roma backgrounds to give their views and experiences on how they tackle Romaphobia and the media. The inclusion of these commentary pieces are very powerful in offering a perspective of active interventions and resistance that we should not forget amidst the depressing continued circulation of racialised stereotypes.     

Frailty models power variance function with cure fraction and latent risk factors negative binomial

In this article, we propose a flexible cure rate model, which is an extension of Cancho et al. (2011 Cancho, V.G., Rodrigues, J., de Castro, M. (2011). A flexible model for survival data with a cure rate: A Bayesian approach. J. Appl. Stat. 38:57–70.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) model, by incorporating a power variance function (PVF) frailty term in latent risk. The model is more flexible in terms of dispersion and it also quantifies the unobservable heterogeneity. The parameter estimation is reached by maximum likelihood estimation procedure and Monte Carlo simulation studies are considered to evaluate the proposed model performance. The practical relevance of the model is illustrated in a real data set of preventing cancer recurrence.     

The Practice of Puxa-Puxa among Mozambican Women: A Systematic Inventory of Motives

Puxa-puxa is the elongation of the labia minora of the genital organs. It is one of the most widespread genital practices among women in Mozambique, and the practice seems to be specific to this country. The motives underlying this practice and its abandonment were examined in a theory-driven way. A total of 616 women currently living in the provinces of Maputo, Zambezia, and Nampula, aged 18 to 62, were presented with one of two questionnaires that contained items about possible motives for practicing puxa-puxa or possible motives for not practicing it. Seven separable motives for practicing puxa-puxa were found, and the most highly rated were “Having a satisfying sexual life”; “Satisfying my sexual partner”; and “Gaining self-control.” Five separable motives for not practicing puxa-puxa were found, and the most highly rated were “Disliking a painful practice”; “Affirming one's value as a person”; and “Avoiding contamination.” The main findings of the study are that the practice of puxa-puxa is associated with deep psychological motives common to most women in most cultures, namely having a satisfying sexual life with a reliable partner, creating the conditions for having children, and being able to care for them. The abandonment of this practice is largely the result of personal decisions, which are not taken under constraint and which are not exclusively taken from fear of illness.     

Accessibility for all: going from theory to practice

The present work demonstrates, through a case study, the importance of theoretical knowledge in practical application of spatial accessibility in order to guarantee equal conditions for all people in the movement and use of space. Initially there was a literature review on the accessibility of space and how design in a accessible way. Next, we show one makeover proposal in one public school that wants to provide access to people with disabilities. This makeover was done and so we could evaluate the buildings changes through the method of accompanied walk with two people. Finally we present the main results and discussions.     

Measuring organizational effectiveness in information and communication technology companies using item response theory

The aim of this paper is to measure the effectiveness of the organizations Information and Communication Technology (ICT) from the point of view of the manager, using Item Response Theory (IRT). There is a need to verify the effectiveness of these organizations which are normally associated to complex, dynamic, and competitive environments. In academic literature, there is disagreement surrounding the concept of organizational effectiveness and its measurement. A construct was elaborated based on dimensions of effectiveness towards the construction of the items of the questionnaire which submitted to specialists for evaluation. It demonstrated itself to be viable in measuring organizational effectiveness of ICT companies under the point of view of a manager through using Two-Parameter Logistic Model (2PLM) of the IRT. This modeling permits us to evaluate the quality and property of each item placed within a single scale: items and respondents, which is not possible when using other similar tools.     

Preliminary Findings on Men's Sexual Self-Schema and Sexual Offending: Differences Between Subtypes of Offenders

Available literature suggests that sexual self-schemas (i.e., cognitive generalizations about sexual aspects of oneself) influence sexual behavior. Nonetheless, there is a lack of research regarding their role in sexual offending. The aim of the present study was to investigate the relationship between the men's sexual self-schema dimensions (passionate-loving, powerful-aggressive, and open-minded-liberal) and different types of sexual-offending behavior. A total of 50 rapists, 65 child molesters (21 pedophilic, 44 nonpedophilic), and 51 nonsexual offenders answered the Men's Sexual Self-Schema Scale, the Brief Symptom Inventory (BSI), and the Socially Desirable Response Set Measure (SDRS-5). Data were analyzed using multinomial logistic regression, controlling for age, school education, psychological distress, and social desirability. Results showed that rapists as well as nonsexual offenders were more likely to hold the powerful-aggressive sexual self-view compared to pedophilic and nonpedophilic child molesters. Overall, findings seem to be consistent with both a sociocultural component of aggression and the general cognitive profile of offenders. If further research corroborates these preliminary findings, sexual self-concept may be integrated into a comprehensive multifactorial approach of offending behavior.

Sliders,visual analogue scales,or buttons: Influence of formats and scales in mobile and desktop surveys

ABSTRACT

In an experiment dealing with the use of personal computer, tablet, or mobile, scale points (up to 5, 7, or 11) and response formats (bars or buttons) are varied to examine differences in mean scores and nonresponse. The total number of “not applicable” answers does not vary significantly. Personal computer has the lowest item nonresponse, followed by mobile and tablet, and a lower mean score than for mobile. Slider bars showed lower mean scores and more nonresponses than buttons, indicating that they are more prone to bias and difficult in use. Sider bars, which work with a drag-and-drop principle, perform worse than visual analogue scales working with a point-and-click principle and buttons. Five-point scales have more nonresponses than eleven-point scales. Respondents evaluate 11-point scales more positively than shorter scales.     

Defective models induced by gamma frailty term for survival data with cured fraction

In this paper, we propose a defective model induced by a frailty term for modeling the proportion of cured. Unlike most of the cure rate models, defective models have advantage of modeling the cure rate without adding any extra parameter in model. The introduction of an unobserved heterogeneity among individuals has bring advantages for the estimated model. The influence of unobserved covariates is incorporated using a proportional hazard model. The frailty term assumed to follow a gamma distribution is introduced on the hazard rate to control the unobservable heterogeneity of the patients. We assume that the baseline distribution follows a Gompertz and inverse Gaussian defective distributions. Thus we propose and discuss two defective distributions: the defective gamma-Gompertz and gamma-inverse Gaussian regression models. Simulation studies are performed to verify the asymptotic properties of the maximum likelihood estimator. Lastly, in order to illustrate the proposed model, we present three applications in real data sets, in which one of them we are using for the first time, related to a study about breast cancer in the A.C.Camargo Cancer Center, São Paulo, Brazil.
