National industry cluster templates and the structure of industry output dynamics: a stochastic geometry approach

Cluster analysis has been widely used in an Input-Output framework, with the main objective of uncover the structure of production, in order to better identify which sectors are strongly connected with each other and choose the key sectors of a national or regional economy. There are many empirical studies determining potential clusters from interindustry flows directly, or from their corresponding technical (demand) or market (supply) coefficients, most of them applying multivariate statistical techniques. In this paper, after identifying clusters this way, and since it may be expected that strongly (interindustry) connected sectors share a similar growth and development path, the structure of sectoral dynamics is uncovered, by means of a stochastic geometry technique based on the correlations of industry outputs in a given period of time. An application is made, using Portuguese input-output data, and the results do not clearly support this expectation.Clusters, Input-output analysis, Industry output dynamics

Psychological violence within a partner relationship and alcohol abuse of Portuguese women: the mediating role of resilience

In this study, we explored how psychological violence within a partner relationship relates to resilience and alcohol abuse of Portuguese women, particularly, testing the mediating role of resilience. A cross-sectional sample of 464 Portuguese women with a partner relationship was screened for psychological violence, alcohol abuse, and resilience. Results showed differences in terms of age, marital status, and current employment situation. Psychological violence was negatively related to resilience and positively related to alcohol consumption. Resilience also showed a negative relationship with alcohol consumption. A partial mediation was found between psychological violence and alcohol consumption through resilience, supporting the crucial role of resilience to break the negative “chain” between psychological violence and alcohol consumption.info:eu-repo/semantics/publishedVersio

Post-traumatic stress disorder in the military police of Rio de Janeiro: can a risk profile be identified?

Background: Significant exposure to critical incidents characteristic of military police work has a potentially traumatic effect and multiple consequences for the mental health of these professionals, such as Post Traumatic Stress Disorder (PTSD). This study aims to investigate the occurrence of PTSD in this occupational group and its correlations with socio-demographic and occupational variables. Methods: This is a cross-sectional study of Rio de Janeiro’s Military Police officers (n = 3.577). Data was collected from self-reported questionnaires applied in an institutional health program. Post-Traumatic Stress Disorder Checklist—Civilian version was used to assess PTSD. Results: Rates of 16.9% for full PTSD and 26.7% for partial PTSD were found. Based on logistic regression analysis, female officers and police officers in lower ranks of the military hierarchy and performing administrative duties were found to be at most risk of developing PTSD. Conclusions: These results suggest the need to further understand the predictive organizational and individual variables of PTSD correlated with the increased vulnerability of professionals in order to contribute to institutional policies for the prevention and rehabilitation of these cases.info:eu-repo/semantics/publishedVersio

Mértola in Late Antiquity: new archeological and epigraphic data

En Mértola se ha encontrado recientemente un considerable grupo de inscripciones paleocristianas que se asocian a dos monumentos de la Antigüedad Tardía. Uno de ellos parcialmente conocido, otro totalmente inédito. Los dos han sido objeto de excavaciones entre 2008 y 2009. Los nuevos textos epigráficos vienen a aumentar la ya numerosa colección epigráfica conocida y a reforzar la idea del uso de las lenguas griega y latina en el seno de una misma comunidad, la del puerto fluvial de Mértola, en el siglo VI d.C.Recently a new group of paleochristian inscriptions and two new monuments were found in Mértola. One of them was already known, but the other was ignored till now. Both were excavated between 2008 and 2009. The new epigraphic texts increase the large epigraphical collection already known, reinforcing the idea that both latin and greek were used within the same community, in the fluvial harbour of Mértola, in VI century a.C

Renormalisation scheme for vector fields on T2 with a diophantine frequency

We construct a rigorous renormalisation scheme for analytic vector fields on the 2-torus of Poincare type. We show that iterating this procedure there is convergence to a limit set with a ``Gauss map'' dynamics on it, related to the continued fraction expansion of the slope of the frequencies. This is valid for diophantine frequency vectors.Comment: final versio

A theoretical approach of adaptation to stress and implications for evaluation and research

[Excerpt] The study of adaptation to occupational stress is a major topic of research on psychology, and other social sciences. In fact, data suggests that employees face significant levels of tension at work, and that there is an increasing of sources of stress, both in terms of intensity and diversity [1]. In this chapter, we analyze adaptation to stress by focusing at the individual level, discussing how professionals evaluate and cope with stressors that impose significant efforts of adjusting. However, this does not mean that occupational stress is strictly an individual phenomenon; by the contrary, a better understanding of stress at work should assume a multifactor perspective, where the employee, the employer, the work organization, the public policies and laws of work, and the cultural values and norms that influence professional relations between all these agents, play together and determine if the working activity will be a pleasant or dysfunctional experience for professionals. Despite the importance of considering all these factors when studying the working activity, it is also obvious that the way each worker adapt to their working conditions is a pivotal factor to understand how this activity can represent a source of personal gratification or, by the contrary, can ended represent a negative, or even indifferent, experience.
