Portuguese Migrants in the German Labor Market: Selection and Performance1

The labor market performance of Portuguese workers in Germany is analyzed in this article. While previous work has compared wages and characteristics of migrants to natives only, this study also matches the data set with an equivalent survey from the sending country. The findings show that Portuguese migrants as a whole are negatively selected, with the exception of blue‐collar workers, the largest group among the movers. The finding that Portuguese migrants earn more than comparable Germans indicates that they have higher unobservable skills.     

A note on the information content of a consistent pairwise comparison judgment matrix of an AHP decision maker

A decision maker using the Analytic Hierarchy Process (AHP) could be consistent, and still provide no information in the resulting vector of priorities. An extreme example would be a pairwise comparison judgment matrix filled with 1s which is totally consistent under the various definitions of consistency, but has provided no information about the prioritization of alternatives resulting from the decision maker's judgments. In this paper, the quality of a consistent decision maker's judgments using the Analytic Hierarchy Process is placed in the context of the entropy of the resulting vector of priorities. Indeed, it is the purpose of this paper to provide a formal definition of this notion ofentropy of a priority vector, and to provide a framework for a quantitative measurement of the information content of consistent pairwise comparison judgment matrices of a decision maker who is using the Analytic Hierarchy Process. We will prove that the entropy of the vector of priorities for consistent matrices follows a normal distribution and discuss some general considerations of this result.     

The endogeneity of union status and the application of the hausman test

Union endogeneity in relative wage equations has been long recognized. Recently, a new specification test, parsimonious in its computational requirements, has been advocated. This paper investigates the suitability of the test in a switching regression framework and critiques its most widely cited application.     

Shaping ways of managing diversity in Portuguese schools,from the student's perspective

This article examines the results of an empirical research project that analysed the political socialisation processes of the students at three Portuguese public secondary schools in the Lisbon Metropolitan Area in 2011. Against the background of the implementation of an ‘education for citizenship’ programme in the official Portuguese school curriculum (2001), the project basically sought to know what attitudes the students mobilised in the face of a hypothetical situation involving the presence of ciganos (gypsies) in a school context. In this respect, and based on a pragmatic and comprehensive perspective, we attempted to test the concept of multiculturality and how it is seen and experienced by the students at these schools. Our aim is to answer the question: In a school context, how do students think the coexistence of gypsies and non-gypsies should be managed? In seeking to answer this question, the methodology that seemed to us most appropriate to this study's objectives is founded on the mobilisation of a scenario-based questionnaire, and to this purpose we surveyed 700 secondary students in a classroom environment. We were able to identify and characterise four possible coexistence formats within the overall framework of a synoptic vision of the available ways of managing a multicultural experience: separation; socialisation; universalism; and co-operation.     

Prevalence of Sexual Problems in Portugal: Results of a Population-Based Study Using a Stratified Sample of Men Aged 18 to 70 Years

Despite the use of different methodologies, target populations, and clinical definitions of sexual problems, recent epidemiological studies have shown that the occurrence of sexual difficulties is a very common experience among men from the general population regardless of their age. The objective of this study was to present epidemiological data on the prevalence of sexual difficulties in a community sample of 650 sexually active Portuguese men, stratified by age, marital status, and educational level. Participants completed a self-reported questionnaire assessing sexual function in the previous four weeks (International Index of Erectile Function). Results showed that sexual difficulties were relatively common among this sample. Rapid ejaculation was the most frequently reported sexual difficulty (23.2%), followed by erectile difficulties (10.2%), orgasm problems (8.2%), and low desire (2.9%) in the previous four weeks. With the exception of rapid ejaculation, all categories showed age-specific prevalence rates, with sexual difficulties increasing gradually in men above age 45. Age was a significant predictor of all sexual difficulties except rapid ejaculation, and lower educational levels were related to orgasm difficulties. Findings are consistent with the majority of epidemiological studies indicating a high prevalence of sexual difficulties among men in the general population and highlight the importance and the need to implement sexual health promotion programs in the target population.     

Mimicry and the Judgment of Emotional Facial Expressions

Lipps (1907) presented a model of empathy which had an important influence on later formulations. According to Lipps, individuals tend to mimic an interaction partner's behavior, and this nonverbal mimicry induces—via a feedback process—the corresponding affective state in the observer. The resulting shared affect is believed to foster the understanding of the observed person's self. The present study tested this model in the context of judgments of emotional facial expressions. The results confirm that individuals mimic emotional facial expressions, and that the decoding of facial expressions is accompanied by shared affect. However, no evidence that emotion recognition accuracy or shared affect are mediated by mimicry was found. Yet, voluntary mimicry was found to have some limited influence on observer' s assessment of the observed person's personality. The implications of these results with regard to Lipps' original hypothesis are discussed.     

Dysfunctional sexual beliefs as vulnerability factors to sexual dysfunction

The differences on sexual beliefs presented by men and women with sexual dysfunction and their sexually functional counterparts were investigated. A total of 488 participants (160 females and 232 males without sexual problems and 47 females and 49 males with a DSM-IV diagnosis of sexual dysfunction) answered the Sexual Dysfunctional Beliefs Questionnaire. Findings showed that, although effects have only reached statistical significance for the female group, both dysfunctional men and women endorsed more sexual dysfunctional beliefs than functional. Women presented significantly more age related beliefs (after menopause women loose their sexual desire, as women age, the pleasure they get from sex decreases) and body image beliefs (women who are not physically attractive cannot be sexually satisfied). Additionally, sexually dysfunctional males presented higher scores (not statistically significant) on 'macho' belief (a real man has sexual intercourse very often) and the beliefs about women satisfaction (the quality of the erection is what most satisfies women). Overall, findings support the idea that sexual beliefs may play a role as vulnerability factors for sexual dysfunction.     

Portuguese PR consultancy websites: Content and presence

The overall objective of this work is to understand the online presence of Portuguese PR, Consultancies associated with APECOM by undertaking an analysis of the content and features of their, websites. This analysis will demonstrate how the PR Consultancies are promoting themselves and their, services.     

Adapting The Revised Self-Leadership Questionnaire to The Portuguese Context

This study aimed to adapt the Revised Self-Leadership Questionnaire (RSLQ) (Houghton and Neck in J Manag Psychol 17(8):672?C691, 2002) for the Portuguese population. 720 professionals, and university and post-graduate students participated in this study. The RSLQ factorial structure was accessed through exploratory and multi group confirmatory factor analysis. From the 9 sub dimensional and 34 items original scale, only 7 sub dimensions and 21 items were preserved. The model tested through cross-validation multigroup analysis proved to be totally invariant across the groups, suggesting good model fit.     

Model selection for stock prices data

The geometric Brownian motion (GBM) is very popular in modeling the dynamics of stock prices. However, the constant volatility assumption is questionable and many models with nonconstant volatility have been developed. In the papers [7 M.L. Esquível and P.P. Mota, On some auto-induced regime switching double-threshold glued diffusions, J. Stat. Theory Pract. 8 (2014), pp. 760–771. doi: 10.1080/15598608.2013.854184.[Taylor &; Francis Online] , [Google Scholar],12 P. P. Mota and M.L. Esquível, On a continuous time stock price model with regime switching, delay, and threshold, Quant. Financ. 14 (2014), pp. 1479–1488. doi: 10.1080/14697688.2013.879990.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]] the authors introduce a regime switching process where in each regime the process is driven by GBM and the change in regime is defined by the crossing of a threshold. In this paper we used Akaike's and Bayesian information criteria to show that the GBM with regimes provides a better fit than the GBM. We also perform a forecasting comparison of the models for two selected companies.
