Work ethic and the legacies of political regimes

This article studies the cross-country differences in work ethic and claims that different political regimes transmitted different work ethics that still persist today. Using the World Values Survey and starting our political regime analysis in 1900, we find that Democratic regimes promote more effectively work relevance and competitiveness than Autocratic and Anocratic regimes, and that the political regime history of the country is more important than the present level of democracy. Moreover, we prove that this differences were transmitted through generations by parents, who optimally choose what work ethic to transmit taking into account their own values.

NSP work project investment styles

This paper analyzes the Nova Student Portfolio (NSP) with the objective to understand performances of the fund. Each investment style has been analyzed (growth, value and momentum) in order to highlight what style allocation contributed positively and which had a negative impact. The results show that the team mainly invested in value stocks, which contributed positively but that its growth investments had a negative impact on the stock picking performance. The stock selection shows a major influence of the value investment style. A statistical approach shows that the market factor was the one explaining the most the NSP returns.

Avaliação do risco de LMEMSLT : aplicação dos métodos RULA e SI / Florentino , António de Sousa Uva

RESUMO - A frequente insuficiência de informação e até, eventualmente, a presença de elementos cientificamente pouco robustos (ou mesmo hipotéticos) no procedimento de obtenção dos resultados finais (scores) com os diversos métodos de avaliação do risco, julga-se determinar a obtenção de distintos resultados no mesmo posto de trabalho e que interessam analisar. O presente estudo foi efectuado numa empresa da indústria automóvel e pretendeu contribuir para a efectividade do processo de avaliação do risco destas lesões em meio industrial. Utilizaram-se como ponto de partida as classificações de risco em postos de trabalho onde a aplicação do método OCRA — base do projecto de norma Europeu prEN 1005-5 para a estimativa do risco de LMEMSLT (Lesões Musculoesqueléticas do Membro Superior Ligadas ao Trabalho) — identificou níveis de risco moderados e/ou elevados (score OCRA ≥ 16,5). Assim nos postos de trabalho (n = 71) registou-se em vídeo a actividade de trabalho. Analisaram-se os principais factores de risco (postura, força, repetitividade e exposição a vibrações) com uma amostragem de segundo em segundo e aplicaram-se dois métodos: 1) RULA (McAtamney; Corlett, 1993); 2) SI (Moore; Garg, 1995). Dos resultados globais da aplicação dos métodos identificam- se discrepâncias evidentes: o método SI classificou 41 postos de risco elevado e o método RULA classificou apenas 26 postos de risco. Destaque para as divergências entre os postos classificados de risco elevado como, por exemplo: de entre os 41 postos com scores de risco da aplicação do método SI apenas se encontram 12 postos classificados de risco pelo método RULA. Os resultados permitem evidenciar validades preditivas diversas para os factores de risco analisados: 1) situações de aplicação de força (SI = 0,80; RULA = 0,66); 2) presença de posturas extremas (SI = 0,68; RULA = 0,48); 3) repetitividade (SI = 0,35; RULA = 0,43). Conclui-se pela divergência de resultados dos métodos SI e RULA aplicados nos mesmos postos de trabalho que tal situação alerta para a pertinência da utilização de um filtro que permita a identificação dos factores de risco presentes em cada posto de trabalho e que, por consequência, oriente a selecção do método mais indicado ou ainda, em oposição, do método contra-indicado. Este trabalho, como um contributo para uma efectiva identificação e avaliação do risco de LMEMSLT, conduz, no limite, à necessidade de elaboração de uma «grelha» das «grelhas» e de informação mais precisa sobre os métodos e sua aplicação, permitindo, desse modo, uma mais efectiva gestão do risco destas lesões.

‘Wooden Man’? : Masculinities in the Work of J. M. Coetzee (Boyhood, Youth and Summertime)

In seeking to advance the possibility of justice, gender and postcolonial studies have argued for the importance of the study of masculinities, through the acknowledgment that a richer understanding of such gendered formations may provide the basis for recognition of the Other and that, left uncriticised, such formations may be continuously delineated by the reproduction of systems of domination. The current study finds as its object the representations of masculinities in J. M. Coetzee’s Boyhood (1997), Youth (2002) and Summertime (2009). As works of transition in terms of Coetzee’s oeuvre - post-apartheid and post-Disgrace - the trilogy provides an account of the development of a man through several stages of life. While portraying the tensions of different geographical and cultural locations, such as apartheid South Africa and the London of the Sixties, the trilogy articulates the various norms that impact in the formation of gender, particularly of masculinities, through a complex system of power relations. The adherence to such norms is never linear, as the trilogy provides imaginative accounts of the contradictions that assist in the formulation of gender, depicting both the allure and the terror that constitute hegemonic masculinity. Located in the intersection of gender and postcolonial studies, the present study is based on the works by Raewyn Connell on masculinities. Animated by such a critical framework, the main research question of the present study is whether the trilogy advances a notion of masculinity that differs from the traditional rigid model, that is, whether there is resistance to hegemonic masculinity and what the spaces inhabited by the subaltern are. It is suggested that the trilogy presents the reader with instances of resistance to normative formulations of masculinity, by contrasting domination with the possibility of justice, and advancing an understanding of the often fatal consequences of gender norms to one’s sense of being in the world.

Seasonality, parity rates and transmission indices of Mansonella ozzardi (Manson) (Nematoda: Onchocercidae) by Cerqueirellum argentiscutum (Shelley & Luna Dias) (Diptera: Simulidae) in a lower Solimões River community, Amazonas, Brazil

Mansonella ozzardi is transmitted by two dipterian families, Ceratopogonidae (midges) and Simuliidae (black flies). In Brazil, black flies are vectors for this filariasis until now. In this paper, we determined the seasonality, parity capacity and parasitic infection rate of Cerqueirellum argentiscutum. The work was carried out in the Porto Japão community, Lower Solimões River, Amazonas, Brazil. Results show that the black flies were more abundant during the rainy season (from December to May). The number of parous flies was higher in every sampling during the course of year. Monthly Biting Rate (MBR1 123742.00, MBR2 86701.50) was high, although Parasitic Infection Rate (PIR1 0.06, PIR2 0.08) and Annual Transmission Potential (ATP 7.25) were low in numbers.

The impact of work clothing design on workers’ comfort

Physical and physiological comfort, at work and during leisure time, is important to human health and motivation. A growing number of jobs require workers to sit. Most clothes, except those intended for wheelchair users, were designed for walking or the standing position. Clothing designs should be user-oriented and meet users’ needs. Garment design should conform to body position and posture, not just shape and size. In this paper we present the ergometric impact of a new type of trousers designed to adapt to changes in position. Concentrations of compression forces, temperature and pressure were documented in an exploratory pilot study and contrasted to traditional designs. The new trousers showed significant decreases in compression force concentration, especially in and around the knees and waist. Most participants identified comfort as an important factor when purchasing a pair of trousers and that, for working purposes, they would prefer these special trousers rather than traditional designs.

Measuring university-to-work success: development of a new scale

Purpose – The purpose of this paper is to develop a subjective multidimensional measure of early career success during university-to-work transition. Design/methodology/approach – The construct of university-to-work success (UWS) was defined in terms of intrinsic and extrinsic career outcomes, and a three-stage study was conducted to create a new scale. Findings – A preliminary set of items was developed and tested by judges. Results showed the items had good content validity. Factor analyses indicated a four-factor structure and a second-order model with subscales to assess: career insertion and satisfaction, confidence in career future, income and financial independence, and adaptation to work. Third, the authors sought to confirm the hypothesized model examining the comparative fit of the scale and two alternative models. Results showed that fits for both the first- and second-order models were acceptable. Research limitations/implications – The proposed model has sound psychometric qualities, although the validated version of the scale was not able to incorporate all constructs envisaged by the initial theoretical model. Results indicated some direction for further refinement. Practical implications – The scale could be used as a tool for self-assessment or as an outcome measure to assess the efficacy of university-to-work programs in applied settings. Originality/value – This study provides a useful single measure to assess early career success during the university-to-work transition, and might facilitate testing of causal models which could help identify factors relevant for successful transition.

Bootstrap performance profiles in stochastic algorithms assessment

Optimization with stochastic algorithms has become a relevant research field. Due to its stochastic nature, its assessment is not straightforward and involves integrating accuracy and precision. Performance profiles for the mean do not show the trade-off between accuracy and precision, and parametric stochastic profiles require strong distributional assumptions and are limited to the mean performance for a large number of runs. In this work, bootstrap performance profiles are used to compare stochastic algorithms for different statistics. This technique allows the estimation of the sampling distribution of almost any statistic even with small samples. Multiple comparison profiles are presented for more than two algorithms. The advantages and drawbacks of each assessment methodology are discussed.

The effects of introducing the Amazonian squirrel monkey on the behavior of the northeast marmoset

The squirrel monkey Saimiri sciureus, an endemic primate of the Amazonian Basin, has been introduced in many localities of the Atlantic Forest biome. Introduced exotic species gain a competitive advantage in their new environment because of a lack of natural predators, competitors or diseases. This advantage can result in a reduction in the resources for the endemic species. The aims of this work were to evaluate the level of adaptation, and monitor the forms of interaction and the impact caused by S. sciureus on the behavior of the native species Callithrix jacchus in the Saltinho Biological Reserve, Tamandaré, Pernambuco, Brazil. The behavior was assessed by use of scan sampling method, every 5 min. A total of 382 h (191 h or 2,292 scans per group) of time sampling was performed. Sixteen interactions were recorded. The interaction index was low and represented 2.4% of the total observation time. Interactions were significantly higher during the dry season (58.5%) relative to the rainy season (41.5%). Callithrix jacchus was intolerant to the presence of S. sciureus and the last one was more tolerant during the interactions. In the presence of S. sciureus, C. jacchus eating, foraging, resting, socializing, and self-grooming behaviors were reduced while alertness was increased. Territorial behavior showed no significant difference. In the presence of S. sciureus, on average, the group of marmosets assembled at a higher layer of the forest stratum. The results might indicate a negative effect of S. sciureus on the native species, C. jacchus.

Establishing the prevalence of hypertension. Influence of sampling criteria

OBJECTIVE: To compare the prevalence of systemic hypertension in two different populations: a representative sample of the adult urban population of Porto Alegre, and individuals who sought blood pressure measurement in a hypertension prevention and control campaign. METHODS: A cross-sectional study was carried out involving a representative sample of the adult urban population of Porto Alegre and a population sample obtained from a hypertension prevention and control campaign, which included all the individuals who sought the blood pressure assessment unit at the Hospital das Clínicas in Porto Alegre. The following parameters were investigated: history of hypertension, use of antihypertensive drugs, age, and sex. Adjustments for age and sex in the prevalence rates were performed to make them comparable. RESULTS: Hypertension prevalence, defined as values > or = 160/95mmHg or treatment with antihypertensive drugs, was higher in the campaign sample (42%) as compared with the population sample (24%). Among those who were aware of their hypertensive condition and were under medication, 54% of the campaign sample and 62% of the representative population sample maintained their pressure levels <160/90mmHg. CONCLUSION: Prevalence rates of hypertension differed a lot in the campaign sample and in the representative population sample, showing that the sampling criterion may influence assessment of risk factors and bias the association between risk factors and health aggravations.

Interpersonal and attitudinal factors in women's work role: Cross-cultural comparison

The last four decades have seen a dramatic increase in the number of women entering employment. This is particularly true in Europe and although more European women are working outside the home, the patterns of female employment have changed very little. An analysis of these patterns is presented. It was found that women continue to dominate specific fields, particularly teaching and service providing. An investigation of the interpersonal behavior differences among 117 American women from the southeastern United States in three work roles--homemakers, women in traditional occupations, and in nontraditional occupations--was conducted and the sex-role orientation, attitudes toward success, and demographic indicators were examined in order to consider the interplay of these variables with female occupational role and interpersonal behavior. A second focus of the study is on the cross-cultural comparison of the psychological and work variables in women of two different cultures: America and Portugal. Thirty-one Portuguese women were a preliminary comparison sample. The American results showed significant differences between groups in self-perceived interpersonal behaviors and the findings contradicted current stereotypes. The cross-cultural data, although preliminary, indicates differences between the countries in social desirability, aggressive and assertive behaviors, and in sex-role attitudes, which seem to reflect the different stages of economic development.

The construction of professional identities in the contexts of work

This chapter identifies and analyzes some characteristics of working situations that are important in the construction of professional identities. It is claimed that professional identity presumes a dynamic process and is constructed and reconstructed in social situations and interactions. Work has a central place in the life of individuals and societies. The contexts of work are places par excellence for investment, expression, negotiation and recognition of the actor themselves and of others. They are, thus, situations for the attribution offeelings about work, ofrelational transactions, oflearning and production of professional know ledge, which are fundamental elements in the (re )construction of professional identity and which are emphasized here below.
