Effects of the social dominance orientation on environmental attitudes of Chilean university students / Efectos de la orientación a la dominancia social sobre las actitudes ambientales de universitarios chilenos

By adopting a multidimensional approach to environmental attitudes (apathy, anthropocentrism, connectedness and emotional affinity with nature), this study explores the relationships between these dimensions, social dominance orientation (SDO) and political orientation. Two hundred and sixty-two Chilean university students filled out an ad hoc online questionnaire. Two confirmatory factorial analyses showed the four typologies of environmental attitudes and the two factors for SDO, which are labelled group dominance and opposition to equality. Through hierarchical regressions, group dominance showed higher explanatory power of environmental attitudes than political orientation. Furthermore, using the bootstrap procedure we showed that group dominance mediated between political orientation and attitudes of apathy, anthropocentrism and connectedness, while opposition to equality mediated between apathy and emotional affinity. We conclude that SDO is an important variable for measuring political ideology while also providing new nuances when analysing the relationships with environmental attitudes.     

Inequality and fiscal policies in Uruguay by race

The aim of this study is to analyze the effect of fiscal policy by race, disaggregating to consider Uruguayans with primarily European, African and indigenous ancestry. We perform an incidence analysis, an estimation of the effect of fiscal policy on the poverty exit rate and an assessment of the impact on the average ethno-racial gaps. The findings support the idea that fiscal policy reduces (but does not eliminate) ethnic gaps. This result is led by health care and educational transfers, and to a lesser degree by direct transfers. We do not consider quality issues with public services, which may affect the estimated narrowing of gaps. Finally, we find that Afro-descendants and indigenous individuals do not capture the full potential of education transfers because of their high drop-out rate.     

Musicians' social representations of health and illness: a qualitative case study about focal dystonia

Musicians are artists who use the entire body when playing their instruments. Since over-practicing may lead to physical problems, musicians might encounter focal dystonia, a hand's motor disorder. The cause seems to be the brain's confusion between afferent and efferent information transfer provoking a disharmony with the instrument. Although focal dystonia may have serious consequences for a musician's career, it is unclear how musicians perceive this trouble. This case study describes two musicians with focal dystonia. Qualitative research was used to study their social representations of health and illness. The results show the central role of the hand during music playing, the passion for music and the understanding for focal dystonia as "brain panic". Therapists should account for those specific features inherent to this population in order to better help them in their quest for art through music. Giving a voice to musicians may improve their quality of care.     

An experimental investigation of transitivity in set ranking

A decision under ‘complete uncertainty’ is one where the decision maker knows the set of possible outcomes for each decision, but cannot assign probabilities to those outcomes. This way, the problem of ranking decisions is reduced to a problem of ranking sets of outcomes. All rankings that have emerged in the literature in this domain imply transitivity. In the current study, transitivity is subjected to an empirical evaluation in two experiments, where subjects are asked to choose between sets of monetary consequences. After analysis with a Bayes Factor, very few violations of transitivity were found. It can be concluded that transitivity seems a plausible condition for the ranking of sets of monetary consequences.     

Brown rats (<Emphasis Type="Italic">Rattus norvegicus</Emphasis>) in urban ecosystems: are the constraints related to fieldwork a limit to their study?

Nowadays, the majority of human beings live in urban ecosystems, with this proportion expected to continue increasing in the future. With the growing importance of urban rat-associated issues (e.g. damages to urban infrastructures, costs of rat-control programs, rat-associated health risks), it is becoming indispensable to fill the identified gaps in knowledge on the urban brown rat regarding, among others, its density, home range, genetic structure, and infectious status. In this context, live-trapping is a crucial prerequisite to any scientific investigation. This paper assesses the main constraints and challenges regarding the urban field and describes the major steps to be considered when planning research on urban rats. The primary challenges are i) the characterization of the urban experimental unit; ii) the choice of a trapping design: the use of live-trapping in capture-mark-recapture design, in association with modern statistics, is highly recommended to answer ecological questions (although these methods, mostly developed in natural ecosystems, need to be implemented for the urban field); iii) the potential ethical considerations with regard to animal welfare and field-worker safety; iv) the building of mutually-beneficial collaborations with city stakeholders, pest control professionals, and citizens. Emphasis must be put on communication to the public and education of field-workers. One major need of modern urban rat research is a peer-validated field methodology allowing reproducibility, repeatability, and inference from urban field studies and enabling researchers to answer long-standing key questions about urban rat ecology.     

Nadaraya–Watson estimator for I.I.D. paths of diffusion processes

This paper deals with a nonparametric Nadaraya–Watson (NW) estimator of the drift function computed from independent continuous observations of a diffusion process. Risk bounds on the estimator and its discrete-time approximation are established. The paper also deals with extensions of the PCO and leave-one-out cross-validation bandwidth selection methods for our NW estimator. Finally, some numerical experiments are provided.     

A Review Essay on the Measurement of Child Well-Being

Research on indicators related to the state of child well-being is a growing field that has experienced several changes over time. The growing supply of data on children, as well as the need to facilitate conclusions and to track trends, has led researchers to develop a number of child well-being indexes. This paper critically reviews the most recent and relevant child well-being indexes, i.e., the Index of Child and Youth Well-Being in the United States, the Child Well-being Index for the European Union, the Microdata Child Well-being Index, and the Deprivation Index. The study focuses primarily on the contributions and innovations the indexes have brought to the field, making a critical assessment of the methods used in the construction of the indexes and identifying their main limitations.     

Unthinking the European Higher Education Area – differentiated integration and Bologna's different configurations

Differentiated integration was conceived of as a political methodology and as a technology to achieve a European “union” in the field of knowledge policies. However, the non-achievement with regard to the political goals of the European Higher Education Area has highlighted the limitations of this approach to promote furthering the EHEA. In this paper, unthinking is both a research strategy aiming to question those limits and a pedagogical tactic to question the assumptions about the futures. As a research strategy, articulations between unity and diversity are examined. Based on the analysis of the documents endorsed by the Education Ministers in keeping the pace of the Bologna process, the paper contributes to expand knowledge on the nature of Bologna’s differences and underlines the paradoxes in dealing with those differences. As a pedagogical tactic, unthinking questions the assumptions about the future scenarios sketched for higher education. Alternative ways to further integration are discussed on the basis of the idea of integration of the “differences”, bringing to the centre education as a political concern, as higher education institutions, professors, and students/graduates are those at the core of the political management of the “differences”.     

全球边疆：美国对外关系中的比较史与边疆研究路径

长期以来,美国对外关系研究的新路径并没有对例外论者的假设构成挑战,同时也无法对全球范围内的美国经验提供一个比较视角。最近开展的边地（borderland）和边疆（frontier）研究则为历史学家提供了一个深入到文化遭遇、文化认同转变以及国家政治边缘的富有价值的视角,并可以对周边地区的人力和自然资源如何整合到更大的经济交换体系这一过程进行分析。在对边疆研究的域外经验与实践进行系统梳理之后,本文指出,有必要将边疆路径引入美国对外关系研究的领域,这样不仅有助于相关研究的推进,而且能够突破特纳理论的局限,进而更全面地看待包括当代跨国市场等在内的美国的内部发展与海外扩张历程。     

Physical and postural aspects of teachers during work activity

Studies indicate that teachers constitute a professional segment, in which the work characteristics and the demands originating from the act of teaching, favor the emergence of sickness, concerning physical or emotional aspects. The present work aimed to describe physical and postural aspects during the working activity of teachers. A total of 120 elementary school teachers (1st to 8th grade) took part in the survey. For data collection, a questionnaire was applied: it included personal and occupational information, perception of discomfort and being off work; physical strength activities; posture at work and physical conditioning activities. The average age of teachers of the present sample corresponds to 35,8 years. In relation to activities which generate more physical strength, the answer none of the activities was predominant with 30 answers; followed by writing on the board, standing up during the period of classes, explanation of the subjects, class elaboration, correction of homework and others. The area of the body with higher amount of occurrences and prevalent discomfort referred to the lower limbs and spinal cord. These data inform the necessity of investing in prevention programs for the teachers, in order to develop strategies into the organizational context and interventions at the work environment.
