Desenvolvimento psicossocial e ansiedades nos jovens

Este estudo, baseado na perspectiva do desenvolvimento psicossocial de Erikson, teve como principal objectivo estudar a relação entre as diferentes tarefas desenvolvimentais e a ansiedade nos jovens. Na presente investigação foi utilizada uma amostra de 511 jovens portugueses, com idades compreendidas entre os 17 e os 26 anos, que frequentavam diferentes cursos universitários em estabelecimentos de ensino superior da área metropolitana do Porto. De modo geral, verifica-se que a uma resolução das tarefas psicossociais de forma construtiva corresponde uma menor tendência para a ansiedade. Relativamente ao género, registam-se efeitos significativos nos medos, pensamentos obsessivos e comportamentos compulsivos e nos estádios do desenvolvimento psicossocial. Verifica-se que o género feminino assume médias mais elevadas na maior parte dos medos e o género masculino nas características obsessivo- compulsivas. O efeito do género nas diferentes tarefas psicossociais só se mostra significativo para a confiança vs. desconfiança em que as raparigas apresentam médias mais baixas comparativamente aos rapazes e médias mais elevadas na tarefa da indústria vs. inferioridade.This research, based on the Erikson’s psychosocial development perspective, has as its fundamental goal to study the relations between developmental psychosocial tasks and anxiety in young people. In this study we used a sample of 511 Portuguese young people, with ages between 17 and 26 years, which attended several higher education courses in the Porto area. Globally, results show that a constructive resolution of psychosocial tasks corresponds to a smaller tendency for anxiety. Results also allow the understanding of the specific contribution each stage has concerning the development of different anxious structures. As for gender, results indicate the presence of significant effects for fears, obsessive thoughts and compulsive behaviours, as well as for psychosocial developmental stages.info:eu-repo/semantics/publishedVersio

Mixing efficiency on plant cell growth and proteinase production in a stirred tank reactor

Mixing efficiency is one of the most significant factors in bioprocess productivity. The major role of agitation is to improve broth homogenization, mass and heat transfer inside the bioreactors

Alpha-Hemoglobin-Stabilizing Protein: An Erythroid Molecular Chaperone

Alpha-hemoglobin-stabilizing protein (AHSP) is an erythroid-specific protein that acts as a molecular chaperone for the free α chains of hemoglobin. Evidence strongly suggests that AHSP participates in hemoglobin synthesis and may act to neutralize the cytotoxic effects of excess free alpha-globin subunits that accumulate both in normal and beta-thalassemic erythroid precursor cells. As such, AHSP seems to be essential for normal erythropoiesis, and impaired upregulation of AHSP may lead to premature erythroid cell death, resulting in ineffective erythropoiesis. Reduced AHSP mRNA expression has been associated with clinical variability in some cases of β-thalassemia. It has been shown that αHb variants may also impair AHSP-αHb interactions, leading to pathological conditions that resemble α-thalassemia syndromes. The aim of this paper is to summarize current information concerning the structure and function of AHSP, focusing on its role in normal erythropoiesis and its relevance in health and disease

The performance of an aerated stirred tank reactor on VHG batch fermentations

The quest for new and renewable energy sources has greatly increased due to the depletion of fossil fuels reserves. Agro-food wastes appear as a cheap and renewable energy source that can contain great amounts of carbon to be transformed in bioethanol that can be used as additive to gasoline

Cinética do crescimento de células em suspensão de Cynara cardunculus em reactores biológicos

Tese de Doutoramento, Biotecnologia Vegetal, Unidade de Ciências e Tecnologias Agrárias, Universidade do Algarve, 1994A espécie vegetal Cynara cardunculus L., vulgarmente conhecida por cardo das hortas ou cardo do coalho, encontra-se disseminada por toda a bacia mediterrânica, quer sob a forma espontânea quer sob a forma cultivada. Para além de diversas aplicações no campo terapêutico, das suas folhas e raízes, é reconhecida a elevada capacidade das flores para coagular o leite. Esta propriedade tem sido atribuída à presença de proteases na planta e tem possibilitado a utilização, no nosso país, das flores secas desta planta, no fabrico artesanal de queijo.The thistle Cynara cardunculus L. is wide spread in the mediterranean and is traditionally used in Portugal in farm house cheese-making, due to the milk clotting activity of the proteases. It has also been used, since early days, as medicine and has several curative properties

Contribution of strategic information distribution to the decision making processes - an empirical

As an organizational asset, data is one of the great sources of competitive advantage of organizations, so that its publication and storageg, aligned with the organizations\u27 strategic and operational metrics, has become a matter of great discussion and concern among decision makers. This study aims to carry out a study about the contributions of the strategic distribution of information to decision-making processes in organizations. The methodology used, of an exploratory qualitative nature, applied the study of multiple cases, through the collection and analysis of data from semi-structured interviews with several employees of organizations that use tools for collecting, processing and disseminating information. The research shows how the information and technologies applied to its treatment collaborate with decision-making processe

The methodology is presented as a qualitative exploratory research using bibliographic procedures, using a multiple case study strategy, with data collection processes through semi-structured interviews with employees of medium and large companies. size of the state of Rio Grande do Sul, which adopt business intelligence solutions and software in their corporate activity and data analysis is done through content analysis. The research highlights business intelligence as a tool for distributing information strategically in decision-making processes within companies

A web-based psychoeducational simulation game for adults in stepfamilies (GSteps)-study protocol for a randomized controlled feasibility trial

BACKGROUND: Stepfamilies are a prevalent family form. However, less stable than nuclear, first marriage families due to the presence of risk factors such as the absence of social norms and the presence of stepchildren. Stepfamilies have unique educational needs regarding stepparenting and co-parenting issues. The development and documentation of psychoeducational intervention strategies can facilitate dissemination of ongoing studies and promote transparency. This article describes the background, design and protocol of a randomized controlled trial (RCT) evaluating the eficacy and feasibility of a web-based Psychoeducational Simulation Game (GSteps). Behavior-modeling video training (BMT) is used to demonstrate and promote relational skills, stepparenting and co-parenting effective strategies for adults in stepfamilies. A mental health professional will be available within the GSteps platform for clarification or emotional support. METHODS/DESIGN: A RCT design is presented to evaluate the outcomes of a self-administered, interactive and web-based psychoeducational Game targeting dyadic marital adjustment and interpersonal skills as the primary outcomes and remarriage beliefs, family function and stepparenting and co-parenting attitudes as the secondary outcomes. Other outcome measures include satisfaction with GSteps, participants’ knowledge learned after the intervention and a purposive sampling method will be used to access feasibility. The minimum required sample size is 112 participants (56 per condition) randomly allocated either to an experimental group (EG), receiving GSteps intervention, or to a wait-list control group (CG). A survey is conducted electronically. Assessments take place at baseline (T(0)), after the intervention (T(1)) and 1-month follow-up (T(2)). DISCUSSION: This protocol presents a RCT aimed at evaluating the efficacy of a web-based psychoeducational intervention (GSteps) designed for improving marital, stepparenting and co-parenting skills in adults who live in stepfamilies. The use of the protocol and results of intervention studies may guide the use and refinement of web-based psychoeducational intervention for stepfamilies. Additionally, GSteps may become a tool for health professionals to enhance stepfamily functioning, stepparenting skills, and marital adjustment of remarried adults
