The red swamp crayfish Procambarus clarkii in Europe: Impacts on aquatic ecosystems and human well-being

Procambarus clarkii is currently recorded from 16 European territories. On top of being a vector of crayfish plague, which is responsible for large-scale disappearance of native crayfish species, it causes severe impacts on diverse aquatic ecosystems, due to its rapid life cycle, dispersal capacities, burrowing activities and high population densities. The species has even been recently discovered in caves. This invasive crayfish is a polytrophic keystone species that can exert multiple pressures on ecosystems. Most studies deal with the decline of macrophytes and predation on several species (amphibians, molluscs, and macroinvertebrates), highlighting how this biodiversity loss leads to unbalanced food chains. At a management level, the species is considered as (a) a devastating digger of the water drainage systems in southern and central Europe, (b) an agricultural pest in Mediterranean territories, consuming, for example, young rice plants, and (c) a threat to the restoration of water bodies in north-western Europe. Indeed, among the high-risk species, P. clarkii consistently attained the highest risk rating. Its negative impacts on ecosystem services were evaluated. These may include the loss of provisioning services such as reductions in valued edible native species of regulatory and supporting services, inducing wide changes in ecological communities and increased costs to agriculture and water management. Finally, cultural services may be lost. The species fulfils the criteria of the Article 4(3) of Regulation (EU) No 1143/2014 of the European Parliament (species widely spread in Europe and impossible to eradicate in a cost-effective manner) and has been included in the “Union List”. Particularly, awareness of the ornamental trade through the internet must be reinforced within the European Community and import and trade regulations should be imposed to reduce the availability of this high-risk species.

the health and well-being of nursing students in clinical practice . what prevents it? what promotes it?

Introduction: The training of nursing students in the context of clinical practice, is characterized by educational experiences, subject to various emotional stress (stress, ambivalence, frustration, conflict), sometimes making it very vulnerable student.However not all students use the same strategies minimizing their meanings and negative effects on the level of your health and well-being Objetiv:To analyze the perception that nursing students have about the determinants of their health status and well-being in clinical practice Methods: Exploratory research Results:The results reveal the complexity of the teaching / learning process in clinical practice, identified determinants that limit and / or promote health and well-being of students, or not contributing to their motivation, self-confidence and learning. All students value the presence of the following dimensions: affective-emotional (humanization in learning experiences); relational dynamics (interactions developed with all stakeholders); methods used (professional competence of the clinical supervisor and teacher); school curriculum (adaptation of learning in theory); socialization to the profession (become nurse).Conclusions: The results indicate, that although all students evidencing the dimensions described as fundamental to learning in clinical practice, the study results are dichotomous and ambivalent. Students 2nd and 3ºanos refer a low perception in clinical practice, the indicated dimensions, and for these source of concern and uncertainty in learning, such as limiting their health condition and well-being. For students of the 4th year, these dimensions are percecionadas as gifts, and sources of motivation, learning and catalysts such as promoting their health and well-being.

Imagens das emoções na infância: Representações sociais da alegria e da tristeza entre crianças em idade pré-escolar

As crianças são muito sensíveis a qualquer mudança no meio familiar ou social. O modo como apreendem, vivenciam e exprimem emoções ou sentimentos, em interacção com o meio - pais, professores e colegas determina, em muito, o seu desenvolvimento, nomeadamente a nível cognitivo, emocional e social. Nesta investigação averiguámos as representações sociais dos sentimentos, em particular da alegria e da tristeza, entre crianças com 5 e 6 anos, de ambos os sexos, que frequentam Jardins de Infância em Lisboa. Enquadrámos teoricamente a investigação na teoria das Representações Sociais (e.g. Moscovici,1976). Os dados foram recolhidos através de desenhos e por associação livre de palavras, a questões colocadas individualmente às crianças, e tratados através de AFO. Os resultados revelaram bastante acerca dos sentimentos das crianças, o que também nos estimula a reflectir sobre o modo mais cuidado para actuar com elas, contribuindo para o seu bem-estar psíquico e social, e aprendizagem. ABSTRACT; Children are deeply sensitive to any change in the family or social environment. The way in which they perceive, experience, and express emotions or feelings when interacting with the environment - parents, teachers, and fellow students - largely determines their development namely on a cognitive, emotional and social level. This research examines the social representations of feelings, particularly of joy and sadness, among children aged 5 and 6 years old, of the both sexes, and attending Kindergartens in Lisbon. On a theoretical perspective, the empirical research is framed on the Social Representations theory (e.g., Moscovici,1976). The data was gathered using drawings and free association, from questions individually made to the children, and examined through FCA2. The results showed quite a lot about the feelings of the children, which also leads us to reflect on the most careful way to act with them, as to contribute to their psychic and social well being, as well as their learning

Relationship between blood pressure and psychological features of experience and behaviour among teachers

Purpose: Relationships between psychic features and psychophysical parameters, such as blood pressure, have a high relevance in research on coping with stress. We want to investigate the correlation between blood pressure and this psychic features. Methods: We investigated 79 teachers from high schools and secondary schools in and around Leipzig, Germany. Using the systolic blood pressure as an indicator, we built three groups: hypotonics, normotonics, and hypertonics. We assessed several health psychologically dependent variables and looked for differences between these groups (Chi-Square-Test). Results: Hypotonics experienced more stress and less planning and goal behaviour. Furthermore, they more often use physical exercises in order to increase their social well-being. Hypertonics, on the other hand, were driven by fear of loss of control and show a higher sense of feeling threatened. Conclusions: We could find for each group different relationships that are highly relevant to health. This results shows how psychological features and physiological regulation mechanisms are linked.

On the Social Aspects of Unemployment: The Case of Life Satisfaction

Unemployment is related to economic, political and social aspects. One of the least analysed social aspects is the relationship between unemployment and the (individual) perceived levels of well-being, such as life satisfaction or happiness. This chapter complements previous work on the subject, using a panel-data econometrics methodology to analyze the relationship between unemployment and life satisfaction in a wide range of countries worldwide. The results confirm that unemployment has a negative effect, statistically significant, on life satisfaction, either for men or for women.

Social Representations of Violence against the Elderly

The repercussions of violence on the mental, social, and physical well-being of the elderly are some of the most challenging problems in public health today. Using a qualitative design, we conducted a study in Portugal and the United States that applied both descriptive and comparative methods in order to understand the social representations of violence against the elderly. Utilizing the Theory of Social Representations, we explored the perspectives of the elderly, their families, and healthcare professionals on the subject of violence against the elderly. The data on which the findings were based were obtained in two very different cultural contexts, yet the representations of violence against the elderly revealed no significant cross-cultural differences. However, conceptualizations regarding expectations of care and protection for the elderly proved to be distinct. We discussed concerns about the general attitudes of tolerance toward violence, including those of the elderly who self-identified as eventual victims. Violence against the elderly was portrayed as a part of old age and also somehow was justified by it. The results also indicated the need to better prepare healthcare professionals and society in general to deal with the consequences of the problem and not, as we would like to report, to prevent it from happening.

Estudo comparativo de professores de ensino regular e educação especial em escolas públicas portuguesas: stresse, bem estar, suporte social e burnout

Sendo a docência umas das profissões onde existem elevados níveis de stresse e burnout, este estudo objetivou comparar estes níveis em professores de ensino regular que trabalham com alunos com Necessidades Educativas Especiais e professores de educação especial. Estudou-se também o bem-estar psicológico manifestado por este grupo, bem como a percepção do suporte social, o qual tem um efeito direto positivo sobre o burnout. Os resultados revelam que, relativamente ao stresse, no grupo de ensino regular são os homens que manifestam um nível mais elevado, enquanto que no grupo de educação especial, são as mulheres. Foram identificadas também diferenças no bem-estar e percepção do suporte social, tendo estes resultados sido obtidos para os docentes de educação especial, homens e mulheres, respetivamente. No que concerne ao burnout, foram observadas diferenças em função do género e habilitações literárias, tendo estas sido verificadas no grupo de professoras de ensino regular que possuem o bacharelato e professores que possuem mestrado e doutoramento. No grupo de educação especial, as diferenças foram obtidas nas professoras com doutoramento e nos homens que possuem a licenciatura; Comparative study of regular education teachers and special education in Portuguese public schools: stress, welfare, social support and burnout Abstract: Being a teaching professions where there are high levels of stress and burnout, this study aimed to compare these levels in regular education teachers who work with students with special educational needs and special education teachers. It is also studied the psychological well-being manifested by this group, as well as the perception of social support, which has a positive direct effect on burnout. The results show that for the stress in the regular education group are men who express a higher level, while the special education group, are women. They were also identified differences in well-being and perceived social support, and these results have been obtained for special education teachers, men and women, respectively. Regarding the burnout, differences were observed in gender and qualifications, and these were verified on the regular education teachers group who have a bachelor's degree and teachers who hold master's and doctorate. In the special education group, the differences were obtained in teachers with doctoral and men who have a degree.
