Asymptotic linearity and limit distributions,approximations

Linear and quadratic forms as well as other low degree polynomials play an important role in statistical inference. Asymptotic results and limit distributions are obtained for a class of statistics depending on μ+X$\mu +\mathbf{X}$, with X any random vector and μ$\mu$ non-random vector with ∥μ∥→+∞$\parallel \mu \parallel \to +\infty$. This class contain the polynomials in μ+X$\mu +\mathbf{X}$. An application to the case of normal X is presented. This application includes a new central limit theorem which is connected with the increase of non-centrality for samples of fixed size. Moreover upper bounds for the suprema of the differences between exact and approximate distributions and their quantiles are obtained.     

States and the nuclear power. An international perspective

This paper analyzes the evolution of public policies on nuclear energy from an international perspective highlighting an interesting sociological paradox: the opposition to nuclear power contributed to the development of the environmental movement; and at present, the promoters of this kind of energy are including environmental arguments in their discourses, the fear of climate change and the reduction of CO₂. Although the Kyoto Protocol does not accept this kind of energy as a clean development mechanism (CDM), its promotion is carried out on the basis of environment objectives, so that the nuclear lobby is obtaining more social acceptation thanks to the environmental discourse in the last four decades. For this research, the nuclear policies at an international level are analyzed inside a wider research about the nuclear debate financed by Encuentro Foundation (Spain).     

School pathways and economic practices of Portuguese Ciganos: some continuities and changes

The main aim of this article is to offer a comprehensive perspective to a better understanding of the actual situation of Portuguese Ciganos.¹ In Portugal, the lack of recognition of Ciganos (Roma) and the sometimes incorrect ‘knowledge’ about them which are reflected in images that are limitative and distorted, suggest inferiority and are full of disdain, all of which negatively affects and restricts the life of Ciganos persons. This article intends to presents some of the main results of two qualitative studies conducted between 2004–2010, one of which sought to get to know Ciganos’ representations of domains, practices and situations perceived as discriminatory, while the other looked at the social integration paths of these persons. These studies produce new knowledge about both individual academic and occupational trajectories, and some of the main intergenerational changes that have occurred among Portuguese Ciganos. In addition, the article offers a new view about some social policies in Portugal and its impacts on Ciganos singularities. In fact, it’s possible to conclude that the universalism of the national social policies has not produced the desired effects in terms of a reduction in levels of poverty, exclusion, discrimination among Portuguese Ciganos.     

Marginal Nested Interactions for Contingency Tables

We introduce a new definition of generalized marginal interactions, called marginal nested interactions, which includes baseline, local, continuation and reverse continuation logits and odds ratios as special cases. The significant aspect of this definition is the inclusion of new types of logits and odds ratios that can handle non-ordinal, ordinal and partially ordered categorical variables in a flexible and appropriate way. It is proved also that the marginal nested interactions define a saturated model of a multi-way contingency table.     

The Activation of Incompetence Schemas in Response to Negative Sexual Events in Heterosexual and Lesbian Women: The Moderator Role of Personality Traits and Dysfunctional Sexual Beliefs

Personality traits and dysfunctional sexual beliefs have been described as vulnerability factors for sexual dysfunction in women, and have also been proposed as dispositional variables for the activation of incompetence schemas in response to negative sexual events. However, no study has tested the role of personality traits and dysfunctional sexual beliefs in the activation of incompetence schemas. The current study aimed to assess the moderator role of neuroticism, extraversion, and dysfunctional sexual beliefs in the association between frequency of unsuccessful sexual episodes and activation of incompetence schemas in heterosexual and lesbian women. An online survey was completed by 1,121 women (831 heterosexual; 290 lesbian). Participants completed the NEO Five-Factor Inventory (NEO-FFI), the Sexual Dysfunctional Beliefs Questionnaire—Female Version (SDBQ), and the Questionnaire of Cognitive Schemas Activated in Sexual Context (QCSASC). Findings indicate that neuroticism moderates the association between frequency of negative sexual events and activation of incompetence schemas in heterosexual women. Moreover, several sexual beliefs also act as moderators of the relationship between negative sexual episodes and the activation of cognitive schemas in both heterosexual and lesbian women. Overall, findings support the cognitive-emotional model of sexual dysfunctions, emphasizing the role of personality traits and dysfunctional sexual beliefs as facilitators of the activation of incompetence schemas in response to negative events in women.     

Interest rate pass-through in the Euro area during the financial crisis: A multivariate regime-switching approach

In this paper we use a Markov-switching vector autoregressive model to analyse the interest rate pass-through between interbank and retail bank rates in the Euro area. Empirical results, based on monthly data for the period 2003–2011, show that during periods of financial distress bank lending rates to both households and non-financial corporations show a reduction of their degree of pass-through from the money market rate. Significant sectoral heterogeneities characterise the transmission mechanism of monetary policy impulses, with rates on loans to non-financial firms being more affected by changes in the interbank rate than loans to households, both in times of high volatility and in normal market conditions.     

Two-Way Street. Moderne(n), Verwobenheit und Kolonialität

By reducing the multiplicity of paths to modernity to the cultural level and attributing Western Europe a key role in generating it, “multiple modernities” authors reinforced the modernizationist notion of an autonomous Western modernity that they themselves criticized. In turn, the post- and decolonial approaches of entangled modernities and modernity/coloniality make colonial ties an important factor in the explanation of global processes. The article first examines these approaches’ relationship to the model of multiple modernities in order to assess conceptual and theoretical similarities and differences between them. Second, the two approaches are considered against the background of their respective empirical reference—India for entangled modernities and Latin America for modernity/coloniality—and possibilities of a theoretical synthesis between them as a potential for South-South dialogue are explored.

Immigrant perceptions of ethnic and racial discrimination: patterns and singularities in a municipality in the Lisbon Metropolitan Area

In Portugal, studies on discrimination against immigrants have focused almost exclusively either on the indigenous population, or on the foreign population. The former have tended to deploy quantitative and extended methodologies, while the latter studies have opted predominantly for qualitative or intensive methodologies, focusing on particular groups. There are few studies in which the immigrant population is extensively surveyed, covering its diverse origins, life trajectories, and social position in the host society.

In this analysis we examine the main factors that shape the perceptions of ethnic and racial discrimination among immigrant groups living in the Oeiras municipality in the Lisbon Metropolitan Area. This analysis is based on a quantitative analysis of a survey of 422 immigrants, of whom approximately half reported having been discriminated against since their arrival in Portugal. The study is focused on three main explanations related to predictive variables: sociographic, acculturation/cultural proximity, and opportunities for contact with the autochthonous population. A multivariate logistic regression demonstrates that there is a statistically significant relationship between perceived discrimination and some sociographic variables including cultural proximity, especially for Brazilians.     

Kommunikation in E-Learning-Veranstaltungen. Erfahrungen der Studierenden und ihre Präferenzen für Online- oder Face-to-Face-Kommunikation

Altogether, 2,196 students from 29 Austrian universities took part in an empirical investigation on learning and communication in e-learning courses. The students completed a questionnaire on their experiences in an actual e-learning course, on their perceived learning achievements, and their enjoyment of the course. Furthermore, they expressed their preferences for online or face-to-face communication. All in all, students were satisfied with their course. They did not prefer one communication setting over another. They preferred online-communication for the distribution of information but advocated face-to-face communication when joint learning and cooperation are important or when socio-emotional relations are to be developed. The results of the study advocate blended-learning designs and give recommendations for which communication purposes online and for which face-to-face settings are more adequate.
