Utilidade das necrópsias para o diagnóstico das doenças

O período neonatal é um dos mais críticos para a sobrevivência dum animal. A morbilidade e a mortalidade nas primeiras semanas de vida são muito eleva- das o que causa elevados prejuízos económicos nas explorações pecuárias, nomeada- mente nas de pequenos ruminantes. A mortalidade nesta fase não pode ser considerada “normal” e por isso des- prezada, mas deverão ser feitos todos os esforços no sentido de identi car as suas causas para que haja posteriormente uma melhoria do maneio, das condições de ex- ploração e se necessário a implementação de medicação adequada. Após cada época de reprodução deve fazer-se uma análise detalhada de forma a tentar perceber quantos animais morreram e com que idade morreram. O ideal será sempre determinar a causa da morte das crias, sendo por isso neces- sário proceder à NECRÓPSIA.info:eu-repo/semantics/publishedVersio

Impact of environmentally sustainable practices on corporate financial performance : empirical findings from portuguese SMEs

Nowadays, we are surrounded by environmental, social, and economic challenges, which have triggered the increasing interest from governments, businesses, and individuals in sustainability. Furthermore, the evidence of the environmental repercussions caused by corporations has intensified the pressures from external and internal entities to shift towards more sustainable businesses. This study aims to assess the relationship between financial performance and the implementation of environmentally sustainable practices. The analysis focuses on Portuguese small and medium enterprises (SMEs) between 2010 and 2017 and intends to understand if financial performance can be an attractive incentive for SMEs to invest in greener practices. A quantitative approach was employed, using a questionnaire database from Instituto Nacional de Estatística (INE). The findings indicate mixed conclusions depending on the measure of financial performance considered and also suggest statistically significant relationships between most of the sustainability and financial performance measures. A negative linkage was concluded between environmental performance measured by green investments and financial performance, when measured as the ROA, ROE, sales growth or assets growth. However, when measuring sustainability as energy efficiency or green hiring the findings demonstrate a non-statistically significant but positive correlation with financial performance. Besides, there is a direct relationship between Debt Ratio and green investing, and overall, a company with a better performance regarding the environment is expected to have higher leverage.Atualmente, estamos rodeados de desafios ambientais, sociais e económicos, que têm vindo a despoletar o crescente interesse dos Governos, empresas e indivíduos por temas de sustentabilidade. Para além disso, a clara evidência das repercussões ambientais causadas pelas empresas tem intensificado pressões de entidades externas e internas para tornar os negócios mais sustentáveis. Este estudo pretende avaliar a relação entre a performance financeira e a implementação de práticas de sustentabilidade ambiental. Com um foco nas pequenas e médias empresas (PMEs) portuguesas entre 2010 e 2017, intenta-se perceber se a performance financeira pode ser um incentivo atrativo para as PMEs investirem em práticas mais verdes. O estudo teve uma abordagem quantitativa, utilizando uma base de dados de questionários do Instituto Nacional de Estatística (INE). Os resultados indicam conclusões mistas, dependendo da medida de performance financeira considerada e sugerem ainda relações estatisticamente significativas entre a maioria das medidas de sustentabilidade e performance financeira. Concluiu-se uma ligação negativa entre performance ambiental avaliada pela dimensão dos investimentos ambientais e a performance financeira, enquanto retorno dos ativos, retorno do capital, crescimento de vendas e crescimento de ativos. No entanto, considerando a sustentabilidade como a eficiência energética ou como a contratação de trabalhadores com responsabilidades ambientais, os resultados, apesar de demonstrarem uma ligação não estatisticamente significativa, revelam uma relação positiva com a performance financeira. Ainda, existe uma relação direta entre o Índice de Dívida e o investimento verde e, em geral, uma empresa com melhor desempenho em relação ao meio ambiente terá maior alavancagem

Changing elderlies strength levels with a four months multicomponent training program

The multicomponent training seems to positively influence elderly’s physical fitness. It is unclear the effects of this type of training with less intervention time in strength levels. Thus, the aim of this study was to assess the effects of a multicomponent training program with four months in elderly’s strength levels. The sample of this study was composed by 30 subjects with 69.30 (± 5.45) years old and 71.80 (± 8.97) Kg. Body weight was assessed with a bioimpedance balance. The knee flection and extension, arm curl and abduction were assessed with a strain gauge in kilograms of force (Kgf). There were no significant differences between the two moments. However, the mean body weight, knee flection and extension strength levels increased. A four months multicomponent training program seem to be insufficient to improve strength levels in elderlies.info:eu-repo/semantics/publishedVersio

o seu impacto no contexto artístico português entre 2000 e 2010 e especificidades no ano 2007

Tese de mestrado, Estudos Curatoriais, Universidade de Lisboa, Faculdade de Belas Artes, 2013This is a study that focuses on young artists prizes in Portugal in the first decade of the XXI century. It begins in the modern cultural prize ascendency, and goes ahead passing through its close relation to competition, providing an alternative to it, cooperation, and exploring that decade more closely to understand if this prize is in fact one of the events evolved in the contemporary art system. EDP Novos Artistas, BES Revelação, Anteciparte, Fidelidade Mundial Jovens Pintores and Concurso Jovens Criadores are the prizes that are here analysed in detail and deconstructed in their elements, regulation, judges and their selection criteria, the exhibition where the selected artists are presented, the prize value and their Maecenas. It presents a collection of the marking point of these artists, selected to these prizes, career, such as schools and courses, exhibition places, grants, other prizes, biennials, fairs and projects. It focuses on the year 2007 in order to understand the impact that this prizes can have in these artists career, based on the exhibition catalogues, interviews with some of the selected artists of this year, André Romão, Pedro Neves Marques, Liene Bosquê, Sónia Almeida, João Biscainho and Simão Palmeirim, and on their curriculum vita

Are consumers beef quality perceptions in accordance with objective beef quality?

The consumer has the final word in food choice, which is determined by his perceived quality. Within a project coordinated by the Faculty of Veterinary Medicine we tried to relate objective quality with the consumer quality evaluation. To do so, we have measured the expected and experienced quality of a sample of Portuguese consumers towards three types of beef (PDO, national and imported) at the shop, and compared this subjective evaluation with the beef objective quality. Results at the consumer level show that respondents perceived PDO beef to be of higher quality than the two other types of beef for different attributes and for overall quality at the shop location. In terms of objective quality results, the three types of beef showed highly similar physicochemical characteristics and there were no differences, on average, in terms of the aspects mostly considered by the consumers - tenderness, colour and fat content. Hence, it was not possible to show that physicochemical characteristics are good predictors of consumer preferences. However shear force revealed a positive asymmetry showing a higher probability to find a tender beef in PDO than in the other types of beef. This should constitute an area for further research.PDO beef, perceived quality, objective quality, Food Consumption/Nutrition/Food Safety, Q130,

Caracterização das explorações de pequenos ruminantes da região da Beira Serra

Dissertação de Mestrado em Tecnologias da Produção AnimalEste trabalho teve como objetivo o estudo das explorações de pequenos ruminantes, através de uma análise do sistema de exploração. O trabalho realizou-se na área geográfica da Beira Serra, do distrito de Coimbra, concelhos de Arganil, Góis, Tábua e Oliveira do Hospital. A informação recolhida é de rebanhos pertencentes aos produtores da Associação Nacional de Criadores de Ovinos da Serra da Estrela (ANCOSE), que foi constituída em 1981 e tem sede em Oliveira do Hospital. Têm como área de intervenção o Parque Natural da Serra da Estrela, alargando-se a outros concelhos, contabilizando na totalidade cerca de 2800 produtores aderentes. Esta associação presta serviços e apoio técnico às explorações, respeitante ao maneio do rebanho de uma forma geral, em 3407 explorações, num total de 89 128 animais. Verificámos que a região Beira Serra ocupa no contexto nacional, um lugar relevante no que diz respeito ao número de explorações, 1964. Esta explorações têm grande tradição e possuem condições propícias para esta atividade, tendo um total de 19 774 animais. Assim sendo, a elaboração deste trabalho visa o estudo das práticas e dos métodos utilizados nestas explorações, a identificação e caracterização das condições da região, conhecer a importância dos efetivos e caracterizar as pessoas que se dedicam à exploração de pequenos ruminantes. De uma forma global, este estudo pretende ser mais um contributo para a identificação das potencialidades, dos estrangulamentos e das perspetivas de evolução deste setor típico desta região. É de denotar que os produtores têm em média 66 anos de idade e possuem mais de 31 anos de experiência, afirmando não haver ninguém para os substituir. A exploração é de índole familiar, os produtores não estão endividados mas também não fazem melhoramentos na exploração. Têm menos de 5 animais por efetivo e não tencionam aumentar devido à falta de saúde e à escassez de mão-de-obra.Todos os produtos resultantes da exploração são para autoconsumo. Os produtores não fazem o desmame das crias, uma vez que não lhes interessa tirar rentabilidade do leite e assim o maneio é mais simples e prático sendo menos trabalhoso. Os produtores dão medicação sem consentimento do veterinário mas respeitam os intervalos de segurança, talvez por já terem tido dissabores.ABSTRACT: The objective of this paper is study in a general way, the livestock farms of small ruminants, through the analysis of the operating system. The work developed in the geographic area of Beira Serra, in the region of Coimbra, Arganil, Góis, Tábua and Oliveira do Hospital. The used data is from flocks belonging to breeders of ANCOSE (National Association of Serra da Estrela Sheep Breaders), which was founded in 1981. They act in the area of the Natural Park of Serra da Estrela, and surrounding areas, having a total of 2800 registered members. This association provides services and technical support to their members, in the management of the herd. Starting with a comparative analysis of flocks from different areas, we do an avaluation of the importance of herds in this region. We verified that this particular region occupies in the national context, an important position regarding the number of livestock farms. These livestock farms have great tradition and very good conditions to this activity. This paper has the aim of studying livestock farms of small ruminants, the ways and methods used, the way they operate, identification and characterization of the region conditions to breeding, learn the way they do it, learn the importance of flocks and understand better the people that dedicate theirs life's to this activity. Identify strenghs and weaknesses, and the future trend of goat and sheep breeding in the region. We can not that producers have about 66 years of age and more than 31 years of experience. They always say that there is no one to replace them. Livestock farm is based on familiar environment, producers normally don't have loans, but are also not eager to improve their facilities. Normally they have less than 5 animals per flock and don't intent to increase the number due to the advance age and lack of workforce, all the products that result from this activity are for own consumption. The producers normally don't wean the offspring, because they don't seek income from the milk and being easier to manage the flock. They usually medicate their animals without proper technical advisement of veteriaries but they respect the safety intervals, probably due to previous setbacks

Towards a classification of technology strategy frameworks

The formulation of a technology strategy is a critical first stage in the process of managing technology inside organizations. Numerous technology strategy frameworks have been proposed in the literature to provide structure to the communication of complex ideas and to contribute to the traceability and transparency of information flows during the strategic decision making process. This research field has evolved considerably in the last decades and the varied contributions indicate a need for a novel classification to support the identification of relevant topics for further research. This paper presents a review of a number of technology strategy frameworks from the scientific literature. These frameworks are analysed according to the attributes (conceptual, applied, static and dynamic) of a meta-framework proposed by Shehabuddeen et al. (2006) aimed at improving the understanding of management frameworks. The frameworks are also analysed through the lens of two prominent schools of strategy: the positioning and resource based view schools. Based on the interpretation of underlying concepts and ideas, the reviewed frameworks are positioned in a three dimensional chart where two axes portray the attributes of the meta-framework and the remaining axis, the opposing schools of strategy. The classification of the reviewed frameworks in divergent axes suggests a dichotomous approach that has been followed in the development of technology strategy frameworks, where new developments attempt to challenge the ideas of previous models. The proposed classification also extends previous models, namely by Arasti and Packniat (2006). In the case of applied frameworks, their observation also revealed that the technology strategy formulation process has been consolidated into four core activities, each one of them encompassing a number of applicable tools. This investigation demonstrates the increasing centrality of the resource based view paradigm in the development of technology strategy frameworks, which can indicate a chaninfo:eu-repo/semantics/publishedVersio

Alternatives to Sedum on green roofs: Can broad leaf perennial plants offer better ‘cooling service’?

Green roof plants alter the microclimate of building roofs and may improve roof insulation. They act by providing cooling by shading, but also through transpiration of water through their stomata. However, leaf surfaces can become warmer when plants close the stomata and decrease water loss in response to drying substrate (typically associated with green roofs during summers), also reducing transpirational cooling. By using a range of contrasting plant types (Sedum mix – an industry green roof ‘standard’, Stachys byzantina, Bergenia cordifolia and Hedera hibernica) we tested the hypothesis that plants differ in their ‘cooling potential’. We firstly examined how leaf morphology influenced leaf temperature and how drying substrate altered that response. Secondly, we investigated the relationship between leaf surface temperatures and the air temperatures immediately above the canopies (i.e. potential to provide aerial cooling). Finally we measured how the plant type influenced the substrate temperature below the canopy (i.e. potential for building cooling). In our experiments Stachys outperformed the other species in terms of leaf surface cooling (even in drying substrate, e.g. 5 oC cooler compared with Sedum), substrate cooling beneath its canopy (up to 12 oC) and even - during short intervals over hottest still periods - the air above the canopy (up to 1 oC, when soil moisture was not limited). We suggest that the choice of plant species on green roofs should not be entirely dictated by what survives on the shallow substrates of extensive systems, but consideration should be given to supporting those species providing the greatest eco-system service potential

Prehospital interventions to reduce discomfort caused by immobilization in adult trauma victims: a scoping review protocol

Objective: The objective of this review is to identify the level of discomfort caused by immobilization as reported by trauma victims, and to map all the interventions in the prehospital context where they have been implemented and evaluated in order to reduce discomfort in adult victims of trauma. Introduction: Immobilization is a cause of discomfort for trauma victims, which has important implications for the deterioration of vital signs and quality of life. However, discomfort caused by immobilization remains an underexplored topic by the scientific community. Inclusion criteria: This scoping review will consider studies of adult victims of trauma, aged 18 years or over, in prehospital emergency care. Studies that focus on interventions designed to reduce immobilization discomfort, implemented and evaluated by health professionals, of any form, duration, frequency, and dose will be considered. Methods: An initial search of PubMed and CINAHL will be undertaken, followed by a second search for published and unpublished studies without time restrictions, in major health care–related electronic databases. Studies in English, French, Spanish, and Portuguese will be included. Data extraction will be performed independently by 2 reviewers in a tabular format and will include details about the level of discomfort, interventions, populations, study methods, and outcomes of interest. A narrative synthesis will accompany the results and will describe how they relate to the review objectives.info:eu-repo/semantics/publishedVersio

Rivalidade ou Violência? A percepção de Estudantes Universitários Vítimas de Violência por parte de Irmãos

This study aimed to investigate the perception of victims of sibling violence (physical, sexual and psychological). It is part of a larger investigation that analyzed the different types of violence and its frequency in early adolescence. In the present study, the participants classified the mistreatments they suffered on the Self-Labelling of Personally Experienced Violence. In the explanation of the occurrences, youngsters enduring all types of sibling victimization (physical, sexual and psychological) attributed “sibling rivalry” significantly more importance than their colleagues who were victims of only one or two violence type(s) (physical, psychological, or psychological + physical + or psychological + sexual). The results are discussed according to ‘normalization of aggression’ perspectives that help to understand the maintenance of abusive behavior towards siblings.Este estudo pretende avaliar a perceção das vítimas relativamente a comportamentos de cariz físico, sexual e psicológico, perpetrados por irmãos. Faz parte de uma investigação mais vasta na qual foram avaliados os diferentes tipos de violência e a sua frequência no início da adolescência. Neste estudo, os participantes classificaram os abusos sofridos com recurso ao Self-Labelling of Personally Experienced Violence. Os resultados indicam que os jovens que sofreram todos os tipos de vitimizações (físicas, psicológicas e sexuais) atribuíram os incidentes à “rivalidade entre irmãos”, de modo significativo, quando comparados com os jovens que só sofreram um ou dois tipos de vitimização (psicológicas, físicas, psicológicas+físicas ou psicológicas+sexuais). Os resultados são discutidos segundo perspetivas de ‘normalização de agressões’, as quais explicam a manutenção de comportamentos abusivos contra irmãos
