Persistence and existence of stationary measures for a logistic growth model with predation

We consider a stochastic logistic growth model with a predation term, and a diffusive stochastic part with a power-type coefficient. We provide criteria for the persistence of the population and for the existence and uniqueness of a stationary measure. Furthermore, we perform a detailed study of the densities of the stationary measures resorting to the forward Kolmogorov equation. We compile our results in a stochastic bifurcation diagram, drawing comparisons with the corresponding deterministic model.     

Counterfactual reasoning,responsibility and blame for serial murders: the perception and prevention of violent crimes / Razonamiento contrafáctico,responsabilidad y culpa de los asesinatos en serie: la percepción y prevención de los crímenes violentos

The present research evaluates people’s perception of serial murders, analysing the effects of controllability in counterfactual reasoning about the past and the future, as well as attributions of responsibility and blame. Besides, the research analyses the effects of perspective (one’s own versus other people’s) in these attributions. Participants were 442 students who answered open-ended questions designed for this study. The first experiment shows that people focus on controllable factors previous to these events. When considering the avoidance and prevention of general serial murders, they focus on representatives of formal authority. Moreover, when judging from their own perspective, blame is attributed to the perpetrator and responsibility to both parties; while from another person´s perspective, they attribute feelings of either responsibility or guilt to the representatives of formal authority and a lack of these feelings to the perpetrator. The second experiment shows identical results regarding the specific case of a well-known serial killer in England and Spain. These findings demonstrate that this perception has implications for the legal framework and the prevention of violent crimes.     

Comparing postcolonial identity formations: legacies of Portuguese and British colonialisms in East Africa

Colonial ties constitute the basis upon which Indian migration to the UK occurred. In the post-war years, while Punjabi migrants more than fulfilled the gap in expanding British industry, Indian elites also arrived to take up professional jobs. During the 1960s and 1970s, in a context of increasingly restrictive (and racially politicized) immigration legislation, there was a significant settlement of the so-called East African Indians, among them an important percentage of East African Gujaratis who had close links with England long before the processes of Africanisation began. Since the 1990s, those East African families also were the ‘hosts’ of a considerable number of Portuguese Indians of Gujarat origin, most of whom had been born in Mozambique during the colonial period and had lived in post-colonial Portugal. This paper will attempt to show how different experiences of intersubjectivity between colonizers and colonized in British and Portuguese African colonial contexts still constitute a source of (re)invention and pluralization of identities within post-colonial Gujarat diasporas settled in the UK. An analysis of these narratives in process will serve to underline the significance of dialectic processes of remaking colonial and post-colonial experiences in order to understand post-colonial identity formations, their ex-tensions and in-tensions, as well as the identity strategies of postcolonial subjects to deal with ‘old’ and ‘new’ multicultural dilemmas.     

Professional Perceptions of Intervention with Families in a Crisis Context

The family institution is a key aspect of the welfare regimes of southern Europe, a crisis-affected situation in which social workers play an important role. This paper analyzes the statements of social workers regarding professional intervention and the families with whom they work within the Spanish context, which involves a strong economic crisis and the reduction of public policies. A relational and qualitative study was conducted of 15 professional perceptions of cutbacks, family demands, the profiles of the user families, and the privatization of social services. In addition, proposals for improvement and challenges are analyzed. The main results involve the relationships among dwindling resources, increasing family demands and family dependence on the system, the disadvantages of privatization, excessive bureaucratization, and adverse labor conditions. The main conclusions include the inadequacy of public policies to meet the needs of at-risk families in a crisis context. About future, the research on professional decision making and professional intervention models will be studied in greater depth.     

Missingness Amount and Mechanisms in Family Economic Stress Research: Mapping (Non)answers to Economic-Related Variables of Fathers,Mothers, and Emerging Adult Children

The percentage of missing data among economic-related items is likely to be particularly high. This study aimed at examining the amount, mechanisms, and variables associated with missingness of different family members participating in a family economic stress study. Portuguese emerging adults (N?=?418) and their parents (N?=?748) were required to answer objective and subjective economic items and complete measures assessing individual and family psychological functioning. Results showed that, for all participants, non-response was more likely to occur among objective economic items than among subjective ones. Children presented higher percentages of item/construct-level missingness than parents, which could reflect a reduced financial awareness on the part of these family members. Although the identification of mechanisms explaining missing data proved to be complex, family members’ missingness was associated with sociodemographic and psychological indicators, suggesting that non-answers do not occur purely by chance. Implications of these findings for further family economic stress research are discussed.

     

Intangible culture,cooperation and intercultural dialogue among university students

This paper focuses on intercultural competence and dialogue across cultural borders between university students from different Portuguese‐speaking countries. Various principles and strategies for intercultural education are summarised, and the project cultures@esec, based on such principles and strategies, is described. The project was focused on cultural heritage. The identities of African students and the intangible culture were also explored. Part of the project involved frequent contacts between domestic and international students, cooperation under equal‐status conditions, joint decision‐making and active learning. Results show that sharing knowledge and ideas, and working under pleasant learning conditions, can help reduce cultural barriers and prejudice and contributes to intercultural sensitivity and competence.

Este artigo centra‐se na competência intercultural dos estudantes universitários de países lusófonas e no diálogo entre culturas. São identificados, de forma sumária, alguns princípios e estratégias de educação intercultural e apresentado o projecto cultures@esec, que se baseia em tais princípios. O projecto esteve orientado para a valorização da herança cultual dos estudantes africanos e respectivas identidades e explorou a cultura intangível dos seus países. O trabalho desenvolvido implicou frequentes contactos entre os estudantes nacionais e estrangeiros, decisões conjuntas e cooperação em igualdade de estatuto. Os resultados mostram que partilhar conhecimentos e ideias e trabalhar em condições de aprendizagem agradáveis ajuda a quebrar barreiras culturais e a combater o preconceito e estimula a sensibilidade e a competência intercultural dos estudantes.     

Cross‐Cultural Validity of Bowen Theory in Southern European Countries

We present a comparison between Italy, Spain, Greece, and Portugal to test the cross‐cultural validity of the Differentiation of Self Inventory Revised (DSI‐R) Scales of emotional cut‐off (EC) and emotional reactivity (ER). Our study focuses on the importance of in‐depth analyses of the differentiation of self‐constructs from a cross‐cultural perspective and reflects on the possibility of conceptualising the universality of Bowen theory in southern European countries. The study involved 1,807 healthy individuals. All participants completed the DSI‐R (Skowron & Schmitt, 2003). It was found that the measurement models had a suitable fit for each country group. Nevertheless, in our study, the two DSI‐R subscales, ER and EC, highlighted a weak invariance, specifically demonstrating only the invariance of the pattern factor loadings and the magnitude of factor loadings in the four samples. The empirical and clinical implications of these data are discussed.     

Obstacles invisibles et représentation des femmes aux postes de décision en Espagne

Les auteurs présentent les résultats d'une étude sur les caractéristiques personnelles et les qualifications d'hommes et de femmes assumant des fonctions de direction dans des entreprises espagnoles, leur situation professionnelle et leur point de vue sur l'égalité des sexes. Par rapport à leurs homologues masculins, les Espagnoles occupant des postes à responsabilités sont plus jeunes mais aussi qualifiées, voire plus, et elles ont moins d'enfants. Cependant, elles sont toujours confrontées à des obstacles qui empěchent la pleine exploitation d'un capital humain précieux. Malgré les mesures adoptées, plus de neuf postes de décision sur dix sont toujours occupés par des hommes.
