um estudo de caso com alunos do 4.º ano de escolaridade

O presente relatório, desenvolvido no âmbito do Mestrado em Ensino do 1.º Ciclo do Ensino Básico (CEB) e de Matemática e Ciências Naturais no 2.º CEB, está dividido em duas partes. A primeira parte é referente à dimensão reflexiva, na qual consta uma reflexão crítica e fundamentada sobre as práticas pedagógicas realizadas no 1.º CEB e no 2.º CEB, uma por capítulo. Para cada uma delas é feita uma breve caracterização dos contextos educativos, sendo apresentadas as aprendizagens e as dificuldades sentidas durante todo o percurso educativo, refletindo sobre os referentes considerados mais significativos, no processo de desenvolvimento de uma (futura) docente. A segunda parte, que corresponde à dimensão investigativa, apresenta um estudo desenvolvido numa turma de 4.º ano de escolaridade, no decorrer da Prática Pedagógica II em 1.º CEB. Este estudo, que tem como base um paradigma qualitativo, procura avaliar o contributo da Metodologia de Trabalho por Projeto para o desenvolvimento de aprendizagens sobre vulcões e sismos, uma temática cujo interesse foi suscitado pelos alunos. Para tal, foram inicialmente recolhidas as ideias e os interesses prévios dos alunos, para posteriormente se implementar a referida metodologia e, por fim, conhecer as perceções dos alunos sobre o processo e identificar as aprendizagens realizadas. Para a concretização destes objetivos, privilegiaram-se, sobretudo, a análise documental (das produções dos alunos), a observação direta participante (com registo escrito, fotográfico e audiovisual) e o inquérito (por questionário e entrevista – focus group). A análise dos dados recolhidos revela que, através da implementação da Metodologia de Trabalho por Projeto, os alunos desenvolveram aprendizagens significativas sobre a temática em estudo e reportam satisfação com esta metodologia de aprendizagem, destacando, no entanto, algumas dificuldades, sobretudo, na fase de execução (e.g., pesquisa) e na gestão do trabalho de grupo.This report, developed as part of the master’s degree in teaching in the 1st Cycle of Basic Education (CEB) and Mathematics and Natural Sciences in the 2nd CEB, is divided into two parts. The first part refers to the reflective dimension, which includes a critical and reasoned reflection on the teaching practices carried out in the 1st and 2nd cycles, one per chapter. For each of them, a brief characterization of the educational contexts is made, presenting the learning and difficulties experienced throughout the educational journey, reflecting on the references considered most significant in the development process of a (future) teacher. The second part, which corresponds to the investigative dimension, presents a study carried out in a 4th grade class, during Pedagogical Practice II in 1st CEB. This study, which is based on a qualitative paradigm, seeks to evaluate the contribution of The Project Method to the development of learning about volcanoes and earthquakes, a subject that students were interested in. To this end, the students' previous ideas and interests were first collected, then the methodology was implemented and, finally, the students' perceptions of the process and the learning achieved were identified. To achieve these objectives, we focused mainly on document analysis (of the students' productions), direct participant observation (with written, photographic, and audiovisual records) and surveys (questionnaires and focus group interviews). The analysis of the data collected reveals that, through the implementation of The Project Method, the students developed significant learning on the subject under study and report satisfaction with this learning methodology, highlighting, however, some difficulties, especially in the execution phase (e.g., research) and in the management of group work

Cork - a natural material for linalool controlled release

Controlled release of aromatic mixtures to the atmosphere is a requirement for scented systems for indoor applications. The product must smell nice, but also be able to last, slowly releasing the perfume over time. Several adsorption materials have been used, for this purpose. In this study, cork was investigated as a potential perfume adsorbent for application in scented drawer sachets and equivalent products. Cork was selected due to its adsorption properties and because it is a natural, renewable, sustainable material. Granulated cork is a significant by‐product in cork industries and it was chosen for adsorption in this work. Linalool, an enantiomeric monoterpene alcohol and one of the main components of several essential oils, was selected as the model compound for adsorption studies. Activated carbon (AC) was used as the reference material. The sorption of linalool to granulated cork and AC was evaluated by HS‐SPME‐GC‐FID. The linalool isotherm on cork was shown to follow a Brunauer‐Deming‐Deming and Teller, Type IV model. The isotherm data on AC can be adjusted to Langmuir and Freundlich models. A maximum adsorption capacity of 3.9x103μg/g was achieved for AC. Desorption studies were performed. Linalool was still released from granulated cork after three equilibrium stages of desorption, whereas only two desorption values were obtained for AC from the equilibrium with highest linalool concentration. Thus, AC demonstrated good adsorption but not good desorption properties. Sorption and desorption studies of linalool from granulated cork, showed that granulated cork could be an excellent material allowing controlled release of the aroma.info:eu-repo/semantics/publishedVersio

Auto-conceito / auto-estima e vinculação nas relações de namoro em estudantes do ensino secundário

Comunicação apresentada no VII Simpósio Nacional de Investigação em Psicologia realizado na Universidade do Minho em Fev. 2010.As relações de namoro, enquanto relações de vinculação, assumem uma importância fulcral no processo de desenvolvimento, com implicações no auto-conceito e na auto-estima. Este estudo visa avaliar o auto-conceito e auto-estima dos adolescentes, bem como a sua relação amorosa numa perspectiva de vinculação. Pretendemos igualmente analisar a relação entre estas variáveis e dados de caracterização sócio-demográfica e da relação de namoro. A amostra é constituída por 149 estudantes do 10.º, 11.º e 12.º anos. Recorreu-se à Escala de Auto-Conceito e Auto-Estima (Peixoto & Almeida, 1999) para a avaliação do auto-conceito e da auto-estima. Para estudar as representações da vinculação de adolescentes ao par romântico utilizou-se o Questionário de Vinculação Amorosa (QVA) (Matos & Costa, 2001). Os dados obtidos permitiram constatar a existência de diferenças em dimensões específicas do auto-conceito em função do sexo dos estudantes. Verificaram-se associações significativas entre aspectos específicos do auto-conceito e a vinculação ao par romântico

Effectiveness of Internet-Based or Mobile App Interventions for Family Caregivers of Older Adults with Dementia: A Systematic Review

Introduction: Global aging presents socioeconomic and health challenges. Dementia, a growing concern, affects millions of older adults, intensifying the burden on family caregivers. E-health interventions offer hope through technological solutions, although current research is limited. This study evaluated the effectiveness of internet-based or mobile app interventions for family caregivers of older adults with dementia. Methodology: A systematic review with a narrative synthesis was conducted using databases (PubMed, CINAHL, Scopus, LILACS, and PsycInfo) and the bibliographies of retrieved articles, with no restrictions on time or language. Results: The search yielded 2092 results, of which 22 studies met the inclusion criteria, encompassing a total of 2761 family caregivers. Twenty-one different outcomes were evaluated and classified into three main types of interventions: psychoeducational, psychotherapeutic, and multicomponent. Conclusions: The study highlights the importance of internet-based and mobile app interventions in supporting family caregivers of older adults with dementia. These interventions positively affect many aspects of caregiver well-being, suggesting their utility in addressing this group’s emotional, social, and self-care needs

Relationship between sense of coherence and health-related behaviours in adolescents and young adults: a systematic review

Background: The sense of coherence is developed through the learning process and contributes to the positioning of individuals in the health-disease continuum, facilitating successful and adaptive personal outcomes. Health-related behaviours represent a health determinant of utmost importance for public health and the development of adolescent and youth health promotion policies, as they are related to the main risk factors and problems of morbidity and mortality in our society. Previous studies have analysed the relationship between sense of coherence and only some individual health outcomes such as oral health, the relationship of sense of coherence with smoking and alcohol consumption, concluding that salutogenic factors are related to quality of life and preventive behaviours. The aim of this systematic review was to describe the relationship of sense of coherence with different health-related behaviours investigated so far in the adolescent and youth population. Methods: A systematic review was carried out in databases (PubMed, CINAHL, Scopus and PsycInfo) and in the bibliographies of the retrieved articles, without limitation of time or language. Associations between sense of coherence and health-related behaviours have been assessed. Results: A total of 1214 investigations were reviewed and 21 of them were included in this systematic review. The relationship between sense of coherence and eight health-related behaviours were identified (alcohol use, physical activity, tobacco use, eating habits, rest periods, use of illegal substances, behaviours related to oral health and time spent in games on the computer). Conclusions: Our results increase the available evidence and support the solid relationship of the sense of coherence with health behaviours both as a protective factor against risk behaviours and for its positive association with preventive and health promoting behaviours of adolescents, young adults and university students

Factors Influencing Nutritional Status in Hospitalized Individuals Aged 70 and above

: Background: Older adults are vulnerable to malnutrition due to physical, psychological, and social factors. Malnutrition, a prevalent and modifiable issue in this population, is associated with an elevated risk of adverse clinical outcomes. The purpose of the study is to assess the nutritional status of older adult individuals admitted to a general hospital and examine its correlation with socio-health and demographic variables. Methods: The study included 239 individuals aged 70 and above, employing a cross-sectional descriptive observational approach with a convenience sampling method. Sociodemographic information was gathered, and variables such as cognitive impairment, functional capacity, comorbidities, medication consumption, and nutritional status were evaluated. Statistical analysis involved descriptive calculations, bivariate analysis, and multivariate analysis, utilizing binary logistic regression. Results: Approximately half of the sample were at risk of malnutrition, with a more notable prevalence among women. Factors such as age (OR = 1.04), cognitive impairment (OR = 1.06), functional dependence (OR = 0.96), and comorbidities (OR = 1.08) were linked to an elevated risk of malnutrition. In our regression model, age, cognitive impairment, and drug consumption emerged as significant predictors of malnutrition risk. Conclusions: Individuals aged 70 and above have a notably high prevalence of malnutrition risk, particularly among those experiencing functional dependence and cognitive impairment. In our sample, cognitive impairment in older adults, coupled with above-median drug consumption, emerges as the primary predictor for malnutrition risk

Into the Wild: A New Approach to the Aquaculture Production of Brown Trout (Salmo trutta L.) to Enhance Restocking Success

The brown trout (Salmo trutta L.) is one of the most iconic native species from European river ecosystems and is also one of the main species of interest for recreational fishing activities (e.g., fly fishing). This species has a significant potential to attract anglers and related investment to the main fishing grounds, which are usually located in poorly developed areas and away from main city centers. Due to its environmental and socioeconomic value, this species is often targeted by management programs directed to the protection and sustainable exploitation of this valuable natural resource. One of the most common actions to enhance the abundance and condition of trout populations is the restocking of wild populations with fish from aquaculture facilities. However, most fish come from fishfarms using production methods such as high densities in the tanks, use of commercial food and standardized feeding methods, lack of environmental stimulus, and domestication of breeding stocks, which usually results in poor fitness and very low survival rates after release. This consequently leads to reduced success of these management actions. To contribute to solving these problems and enhancing the success of restocking actions for the recovery and sustainable enhancement of wild trout populations, we propose a novel approach to the production of this species, by testing and implementing a new protocol that aims to produce wild-reared trout. These fish come from wild breeders and will be produced with the least human contact in conditions that mimic their natural habitat. Taking advantage of a recently remodeled and re-equipped aquaculture facility, located in Central Portugal (Posto Aquícola de Campelo, Figueiró dos Vinhos), we are rearing trout in low densities (10–20 trout/m3 ), like the ones observed in natural habitats, using live food (larvae and insects), and subjected to environmental stimuli such as refuges, and water and flow variability, equivalent to those observed in local streams. Accompanied by a pre- and post-restocking monitoring program (e.g., evaluation of trout abundances and habitat in the target stream, dispersion and movement patterns and survival), this study will contribute to enhancing the success of future restocking actions, promoting the sustainable enhancement of wild trout populations, and, thus, increasing the interest of restocked fishing grounds for angling activities and associated incomes

Amyloid precursor protein interaction network in human testis: sentinel proteins for male reproduction

Background Amyloid precursor protein (APP) is widely recognized for playing a central role in Alzheimer's disease pathogenesis. Although APP is expressed in several tissues outside the human central nervous system, the functions of APP and its family members in other tissues are still poorly understood. APP is involved in several biological functions which might be potentially important for male fertility, such as cell adhesion, cell motility, signaling, and apoptosis. Furthermore, APP superfamily members are known to be associated with fertility. Knowledge on the protein networks of APP in human testis and spermatozoa will shed light on the function of APP in the male reproductive system. Results We performed a Yeast Two-Hybrid screen and a database search to study the interaction network of APP in human testis and sperm. To gain insights into the role of APP superfamily members in fertility, the study was extended to APP-like protein 2 (APLP2). We analyzed several topological properties of the APP interaction network and the biological and physiological properties of the proteins in the APP interaction network were also specified by gene ontologyand pathways analyses. We classified significant features related to the human male reproduction for the APP interacting proteins and identified modules of proteins with similar functional roles which may show cooperative behavior for male fertility. Conclusions The present work provides the first report on the APP interactome in human testis. Our approach allowed the identification of novel interactions and recognition of key APP interacting proteins for male reproduction, particularly in sperm-oocyte interaction.publishe

Migration Patterns and Behaviour of Trout (Salmo trutta L.) in the Southern Limit of the Species Distribution

The trout Salmo trutta L. is an iconic fish species very well studied across most of its range. However, there is a lack of information about the biology and ecology of S. trutta populations from southern European rivers, which coincide with the southern limit of its global distribution. This study aims to analyse the movement patterns and habitat use of S. trutta in the Mondego River basin, Central Portugal, and relate them with the environmental factors to which the species is exposed. Biotelemetry represents an important tool to obtain temporal and spatial specific details about the behaviour of target species and, in this work, we used a set of complementary techniques, namely acoustics, radio and PIT telemetry. A total of 114 trout specimens were tagged with PIT-tags, to be identified in future recaptures or detected at an antenna installed at Coimbra dam fish pass. From these, 18 were also tagged with Dual Mode transmitters, that include radio and acoustic telemetry signals, allowing to track the species’ movements from the estuary to the upstream freshwater sections. Results show the existence of a migratory peak between November and January that coincides with the reproduction season, while reinforcing the importance of Alva River to spawning S. trutta, one of the main tributaries in the study area. River fragmentation in the study area, particularly in the tributaries, is still limiting the vital area of the tracked individuals, although recent restoration actions provided easier access to some important areas in this river for distinct trout life-stages. This study aims to improve the knowledge of southern European trout populations, contributing to enhancing efforts for restoring and managing these populations inhabiting areas under severe climate change effects

Envolvimento Paterno e Temperamento Infantil: Revisão Sistemática de Literatura

Este estudo tem como objetivo apresentar uma revisão sistemática de literatura sobre envolvimento paterno e temperamento infantil, entre os anos de 2006 e 2017. Realizou-se uma busca nas seguintes bases de dados: LILACS, PePSIC, SciELO, Web of Science e PsycINFO (APA), por meio dos descritores father e temperament e seus respectivos termos em português e espanhol. Foram examinados 19 artigos cujo foco de investigação foram a relação entre o envolvimento do pai e o temperamento do(a) filho(a). Os resultados foram divididos em duas categorias: Parentalidade, avaliação e influência no temperamento infantil e Paternidade e temperamento infantil. Verificou-se que o tema vem sendo pouco estudado no Brasil, em comparação com outros países e diversas áreas da saúde. A partir dos estudos analisados pode-se inferir que o pai tem influência direta em todas as fases do desenvolvimento infantil e no temperamento do(a) filho(a), especialmente ao que concerne a socialização e regulação do humor. Portanto, aponta-se para a necessidade de ampliação de pesquisas com este foco, a fim de favorecer e estimular a elaboração de políticas públicas e possibilitar novos modos de fomentar o envolvimento paterno na vida dos(as) filhos(as), considerando as variáveis que interferem nesse fenômeno, como o temperamento da criança
