"Being busy is the only way to recover": occupation and employment influence in drug misuse recovery

A literatura tem identificado a importância do contexto na experiência de recuperaçãode uma adição. Assim, é crucial considerar fatores socio-ambientais como influenciadoresda recuperação, como por exemplo a ocupação, que previne a recaída. Esta investigação estáinserida no projeto europeu D.U.R.E.S.S. (Drug Use Recovery, Environment and SocialSubjectivity), financiado pelo SICAD (Serviço de Intervenção nos ComportamentosAditivos e nas Dependências) e emergiu do projeto europeu do ERANID. Pretendecompreender qual a influência da ocupação na recuperação do abuso de drogas, quais asocupações mais uteis na recuperação e quais as maiores dificuldades e benefícios de ter umaocupação. Cada um dos dezanove participantes em programa de metadona manteve umdiário de saúde durante, aproximadamente, seis meses, onde registaram as suas ideias acercada ocupação. Os dados foram analisados através de uma análise de conteúdo temática. Osresultados sugerem que a ocupação influencia muito a recuperação de abuso de drogas. Asmais importantes são o emprego, os cursos e as atividades ocupacionais, que permitem queos utilizadores de drogas estejam ocupados e não pensem em drogas, tornando a recuperaçãomais fácil. Elas dão-lhes estabilidade, aumento de responsabilidade, autorrealização econtacto social, enquanto permitem a aprendizagem e integração na sociedade. Eles sentemalgumas dificuldades como a relação com colegas, cansaço, stress e injustiças,nomeadamente no que toca ao horário. As ocupações devem ser interessantes e adequadasàs suas necessidades, sendo que os centros de tratamento deveriam criá-las, permitindo odesenvolvimento de competências

Religious discrimination toward other religious groups by descendants of religiously heterogamous versus homogamous parents

This study aimed to develop a model that explains personal attitudes toward religious groups and the role of parental religious heterogamy and homogamy. The sample included 32,595 participants from 26 countries around the world and was obtained from the International Social Survey Programme. Participants whose parents were religiously homogamous presented higher well-being, better health perception, and higher religiosity than participants whose parents were religiously heterogamous. Having had parental heterogamy or homogamy is a moderator of the relationship between religious practice and attitudes toward religious groups, with this relationship being stronger among participants who had parental homogamy. Religious variables are directly related to heterogamy/homogamy and indirectly related to well-being and personal attitude toward religious groups through parents’ religious heterogamy/homogamy. Religious variables are related to personal attitudes toward religious groups through patents’ religious heterogamy/homogamy and well-being. Participants whose parents are religiously heterogamous present a more negative attitude toward Christians, Muslims, Hindus, and Jews, and participants whose parents are religiously homogamous present a more negative attitude toward atheists or nonbelievers. In the context of globalization and the merging of cultures, these results open new research questions and may support religious, spiritual, and clinical practitioners in their approach to religious discrimination.info:eu-repo/semantics/acceptedVersio

Religious identity, religious practice, and religious beliefs across countries and world regions

The aim of this study was to evaluate the structure and measurement invariance of the religious identity, religious practice, and religious beliefs across cultures in six world regions (Asia, non-Western Europe, North America, Oceania, South America, and Western Europe) and across Western, Educated, Industrialized, Rich, and Democratic regions (WEIRD) and non-WEIRD world regions. Confirmatory factory analysis examined whether the hypothesized measurement model fits the data; several multi-group confirmatory factor analyses were performed to examine measurement invariance through a progressive analytic strategy involving three invariance conditions of configural, metric, and scalar invariance. The results generally supported the adequate fit to the data of the three correlated factors model (religious identity-RII, religious practice-RPI, and religious beliefs—RBI); it was found to be full metric invariance for WEIRD regions (RII), North America (RII and RBI), Western Europe (RII) and Non-Western Europe (RII), and South America (RII and RBI). Finally, for RII, it was found to be full configural invariance in almost all regions, except North America and Oceania; for RPI, it was found to be full configural only in North America and Non-WEIRD regions; and for RBI, it was found to be full configural only in North America, Asia, and South America, being that women scored significantly higher than men in all three indices all over the world; finally, it was found to be configural, but not metric or scalar invariance across WEIRD and non-WEIRD world regions.info:eu-repo/semantics/publishedVersio

Comprehensive analysis and evaluation of cogging torque in Axial Flux Permanent Magnet machines

Evaluation and minimization of cogging torque in Axial Flux Permanent Magnet (AFPM) machines become essential specially in direct drives for low speed applications. This paper presents a comprehensive analysis of the cogging torque in AFPM machines designed for low speed applications and mitigation methods are proposed. Evaluation methodologies of the cogging torque based on Finite Element Analysis (FEA) computations are discussed and applied to a double-sided, internal rotor, AFPM reference machine. From the performance comparison of Maxwell stress tensor and virtual work methods on the evaluation of cogging torque, it is possible to conclude that the latter overestimates the amplitude of the cogging torque into a considerable extent.info:eu-repo/semantics/publishedVersio

Bidirectional vehicle-to-grid interface under a microgrid project

In the emergent deployment of smart grids, storage systems play an important role into assets utilization optimization, providing backup power and peak-shaving. This concept becomes more critical in the context of microgrids with a high penetration of renewable energy resources. Plug-in electric vehicles provide an enormous distributed storage capability, which favours the technical and economical exploitation of such systems. This paper presents a comprehensive implementation and control of a bidirectional power converter for vehicle-to-grid integration, based on a bidirectional DC/DC converter followed by a full bridge DC/AC converter.info:eu-repo/semantics/publishedVersio

On the implementation of a microgrid project with renewable distributed generation

This paper describes the on-going implementation of a microgrid project with renewable distributed generation under the context of an initiative with demonstration purposes in an university campus. In the actual context of the electrical energy demand increase and limited conventional resources, along with the consciousness of the climate changes and the need to invest in clean energies, microgrids allows the integration of dispersed energy sources, mainly renewable, which make them cost effective, providing a viable alternative to centralized production, transmission and distribution system for remote community areas. The design concept of the microgrid and a description of the base equipment and energy sources already integrated are presented. From the on-going projects to be integrated on the microgrid, it is presented the Grid-to- Vehicle and Vehicle-to-Grid concept, which will provide a second energy storage element using the battery of an electric vehicle. To accomplish this objective, a bi-directional power converter is being developed and simulation results of its power structure and control are presented

Improving the storage capability of a microgrid with a vehicle-to-grid interface

In the emergent deployment of microgrids, storage systems play an important role providing ancillary services, such as backup power and reactive power support. This concept becomes crucial in the context of microgrids with a high penetration of renewable energy resources, where storage systems may be used to smooth the intermittency and variability of most of them. Plug-in electric vehicles provide an enormous distributed storage capability, which favours the technical and economical exploitation of such systems. This paper presents a comprehensive implementation and control of a bidirectional power converter for Vehicle-to-Grid integration, based on a bidirectional DC/DC converter followed by a full bridge DC/AC converter. The evaluation of the adopted topology and its control is performed through MATLAB/Simulink simulation.info:eu-repo/semantics/publishedVersio

Dark personality traits and online behaviors: Portuguese versions of Cyberstalking, Online Harassment, Flaming and Trolling Scales

The main objective of this study is to assess moderation effects of online behaviors between personality traits and addiction to Internet. To this end, four instruments were validated for Portuguese version through confirmatory factor analysis and exploratory factor analysis (Study 1) Multiple regression analysis was applied to examine the personality predictors of specific online behaviors while controlling for gender and age; and moderation effects were assessed (Study 2). Results showed good psychometric properties for the four validated scales. Machiavellianism is positively associated with all the dimensions of this study. Psychopathy is positively associated with total Cyberstalking, Cyberstalking Control, Flaming and Trolling. Narcissism is positively associated with all the dimensions, except Online Harassment and Flaming. Machiavellianism is positively associated with Addiction to Internet through Cyberstalking, Flaming and Trolling. Psychopathy is positively associated with Addiction to Internet through Cyberstalking Control and Flaming. Narcissism is also positively associated with Addiction to Internet through Cyberstalking and Trolling. This study demonstrates that dimensions of the dark triad of personality play an important role in Internet addiction through online behaviors. The results of this study have theoretical and practical implications: on the one hand, they reinforces the findings of other studies showing that dimensions of the dark personality triad play an important role in Internet and social network addition, contributing to the literature; and, on the other hand, on a practical level, they allow to conduct awareness campaigns in communities, schools, and work to understand that one can be exposed to unpleasant situations due to behaviors that some people with personality traits of Machiavellianism, narcissism and/or psychopathy that may cause problems affecting the mental, emotional and psychological health of others.info:eu-repo/semantics/publishedVersio

Validation of the Portuguese version of Hoge Intrinsic Motivation Religiosity Scale and Rohrbaugh and Jessor Religiosity Scale

This study aims to validate, for the Portuguese population, the bidimensional structure of the Hoge Intrinsic Motivation Religiosity Scale (HIMRS) and the four-dimensional structure of the Rohrbaugh and Jessor Religiosity Scale (RJRS); it also aims to establish an association between the two religious scales and religious identity. To this end, an exploratory factor analysis (EFA) with polychoric matrix (for ordinal data) and a confirmatory factor analysis (CFA) with maximum likelihood estimation (MLE) were carried out. Besides reliability, convergent and discriminant validity were assessed by Cronbach’s alpha coefficient, composite reliability (CR), average variance extracted (AVE), and AVE squared roots. The Portuguese versions of the HIMRS and RJRS presented good model fit. These instruments correlated with each other and with religious identity. Differences in religious motivation and in religious identity concerning sociodemographic variables were found: women, divorced, and older participants define themselves as being more spiritual or religious persons than men, single or married, and younger participants. Also, years of education were positively associated with religious intrinsic motivation and negatively associated with religious extrinsic motivation. This study provides two more instruments with adequate properties to assess intrinsic religious motivations, past-year frequency of religious service attendance, and personal religiosity for the Portuguese population.info:eu-repo/semantics/publishedVersio
