A Comparison of Horse-Race, Bingo, and Video Poker Gamblers in Brazilian Gambling Settings

In the present study Brazilian gamblers from different settings were compared on socio-demographic characteristics, gambling behavior, and use of drugs. The SOGS was administered to 171 subjects at bingo (BG), video poker (VP), and horse-racing clubs (HR) of São Paulo. BG concentrated most women, VP the youngest and single gamblers, and HR the lowest income subjects. More VP than HR or BG gamblers reported taking time off work to gamble, as well as returning another day to win back lost money. They also had a higher number of scorable responses on the SOGS. The differences observed suggest that VP gamblers bear a greater risk of developing a pathological gambling pattern. The authors suggest that measures should be taken aimed at the prevention of pathological gambling, particularly among the young population of video poker gamblers.     

Patient progress modelling and results in Wilm's Tumour

The report describes the development of a mathematical model of the progress of patients with Wilm's Tumour using the methodology developed by Jackson & Aspden [1, 2]. The model incorporates two prognostic factors which are shown to influence patient progress. These are the stage of the tumour and the age of the patient at presentation. The model proved adequate to represent an initial set of patient data, and comparison runs were performed with data from a later time period. These runs highlighted changes in patient progress between the two groups and illustrated the usefulness of the model in this type of analysis. The analysis also underlined the poor prognosis of patients over 5 years old who relapsed.     

Bootstrap Tests of Nonnested Hypotheses: Some Further Results

Nonnested models are sometimes tested using a simulated reference distribution for the uncentred log likelihood ratio statistic. This approach has been recommended for the specific problem of testing linear and logarithmic regression models. The general asymptotic validity of the reference distribution test under correct choice of error distributions is questioned. The asymptotic behaviour of the test under incorrect assumptions about error distributions is also examined. In order to complement these analyses, Monte Carlo results for the case of linear and logarithmic regression models are provided. The finite sample properties of several standard tests for testing these alternative functional forms are also studied, under normal and nonnormal error distributions. These regression-based variable-addition tests are implemented using asymptotic and bootstrap critical values.     

Webster‐Stratton Incredible Years Basic Parent Programme (IY) in child care placements: residential staff carers' satisfaction results

The aim of the present study was to investigate residential child care staff satisfaction with their involvement in the Webster‐Stratton Incredible Years Basic Parent Programme (IY). In an exploratory, not randomized study, 27 professionals from two different short‐term Portuguese residential child care centres (IG1, n = 15; IG2; n = 12) completed weekly IY evaluations and an overall satisfaction questionnaire at the end of their participation in the IY intervention. The weekly level of satisfaction was assessed with regard to each of the programme's components (content, DVDs, group leaders, group discussion). At the last session, they filled out a questionnaire aimed to evaluate the levels of satisfaction regarding the programme overall, the teaching format, the group leader(s) and the usefulness of specific educational techniques they learned. Data indicated that residential staff carers were highly satisfied with the weekly sessions and with the overall usefulness of the intervention programme. Results are discussed in terms of implications and future research directions.     

A new skew-bimodal distribution with applications

The modeling and analysis of experiments is an important aspect of statistical work in a wide variety of scientific and technological fields. We introduce and study the odd log-logistic skew-normal model, which can be interpreted as a generalization of the skew-normal distribution. The new distribution can be used effectively in the analysis of experiments data since it accommodates unimodal, bimodal, symmetric, bimodal and right-skewed, and bimodal and left-skewed density function depending on the parameter values. We illustrate the importance of the new model by means of three real data sets in analysis of experiments.     

A Research Note on Family and Income Distribution: The Equalizing Impact of Married Women's Earnings in Metropolitan Brazil*

Using the 1985 Brazilian Annual Household Survey (PNAD), this study analyzes the extent to which the labor force participation of married women influenced familyincome inequality. The marginal impact on family earnings is decomposed into two components, one generated uniquely by differences in earnings inequality between spouses and another produced by imperfect assortive mating on spouses' earnings. Results show that the correlation among spouses' earnings is significantly less than one (0.4), and that the level of earnings inequality is more than 50 percent higher among wives than husbands. Because these forces are offsetting, wives' labor income has a negligible impact on family-income inequality in Brazil. The results demonstrate the importance of isolating the influence of imperfect assortive mating from that due to inequality in earnings between men and women.     

The Atlantic Slave Trade to Maranhão, 1680–1846: Volume,Routes and Organisation

Maranhão has the best documented slave trade in all Portuguese America. However, it is one of the least studied branches of the Atlantic slave trade. This article provides an assessment of the volume, routes and organisation of the slave trade to Maranhão, in northern Brazil. It shows that, although small in scale, the slave trade to Maranhão displayed important features concerning the routes and organisation of the Atlantic slave trade. Finally, because of the late European occupation and relative isolation, the slave trade to Maranhão offers ideal conditions for observing the rise and fall of African slavery in the New World.     

Building political competencies for the transformation of racism in Aotearoa

Abstract

In the face of enduring systemic racial disparities between Māori and non-Māori, we invite Pākehā health, education and social service professionals to review their ethical conduct and to enhance their political competencies to help transform racism. This paper examines how Pākehā became beneficiaries of racism and how libertarian discourses are used to distract attention away from the associated privileges. Based on experience in the anti-racism movement, we (the Pākehā authors) advocate for the grounding of Pākehā practitioners in a deeper understanding of colonial history. We invite closer attention to structural analysis as a means of gaining the understanding needed to strengthen political competence in order to avoid collusion with institutional racism. We make a case to develop co-intentional relationships with Māori through active whanaungatanga and the applications of the teachings of Freire as pathways for strengthened practice.     

An overview of occupational accidents notification systems within the enlarged EU

This paper describes a comparative analysis of the official forms used for reporting occupational accidents within the EU-27 member states. The comparison is based on two analysis grids (coding schedule) created to that effect, which incorporate a set of evaluation criteria and an interpretation key. The results obtained in the analysis allowed for attention to be drawn to the relevant attributes of such forms in terms of their content and format/structure. It also revealed the main similarities and differences between each country, providing a complete assessment of the 27 member states. The discussion gives account of the level of implementation of the "new" Eurostat variables within the European Statistics of Accidents at Work (ESAW). Furthermore, the study shows that certain formats (structure of information fields) appear to facilitate completeness of the information collected. It has also demonstrated that the European harmonisation process is still far from completion, although the newcomer states seem to be adjusting quickly to the process. The findings of this study may bring useful insights to national authorities and European policy-makers, or to employers/enterprises wishing to implement their internal procedures aligned with the ESAW methodology. The scientific community is another interest group, whose research relies on official statistics, preferably comparable across all countries.
