Josep Claret: arquitectura i societat

El gironí Josep Claret Rubira (1908-1988), arquitecte de professió i artista-dibuixant de vocació, va obtenir el títol l'any 1933, a l'Escola d'Arquitectura de Barcelona. D'ençà d'aquella data i fins a mitjan dels anys 70, va projectar una quantitat enorme d'edificis de múltiples tipologies i nombrosos plans d'urbanització, arreu de les comarques gironines i menorquines. Amb ideologia primerenca propera a les esquerres catalanistes, es va haver d'adaptar al règim franquista, per poder continuar treballant i vivint a Catalunya. Malgrat que inicialment li deuria costar un gran esforç, el procés d'amotllament el va tenir planer (almenys aparentment), gràcies al seu parentiu -per via matrimonial- amb una família que hi estava estretament vinculada. És autor d'obres d'elevat nivell arquitectònic -amb poques que siguin conegudes i reconegudes- i un clar conformador del paisatge de les seves contrades, fet influent en la societat que hi ha estat habitant i que hi viu encara avui dia. La seva arquitectura és un magnífic exemple del que agradava a les generacions de durant cinc dècades. És també autor d'obres que, moltes vegades, no s'adiuen gens amb el que la Història de l'Arquitectura dóna per bones, però que reflecteixen el gust, les preferències i les prioritats d'una societat determinada.

The future of veterinarians in dairy herd health management

The future of the Veterinary Practice in Dairy Health Management has changed and will change more drastically from our point of view in the next years. The consumer’s pressure and the Media are more and more concerned about animal welfare, traceability of animal products and safety of products of animal origin. On the other hand the Farmers in Europe have to produce under strong rules (competing with other countries outside Europe), which are normally very expensive to put in practice, and the veterinarians should adapt their knowledge to the new challenges, because without their work and cooperation, dairy farming will have no future. In that sense, the old veterinary practice has to go in other ways, otherwise the Veterinarians will loose clients and the animal population in Europe will be reduced. The Dairy farmers will ask for support in other areas besides clinical: efficacy, management, welfare, profitability, nutrition, prophylaxis, economics, reproduction, environmental protection, grassland management, etc. Cattle practitioners should be able to give answers in several subjects and this sets the challenge to our profession - Veterinary preparation has to be very strong in single animal species, particularly in Dairy or beef cows. The cattle practitioner has to look beyond, but he should never forget that “the single animal” has to be looked at as one unit of the herd, which means that without a very good knowledge of the single animal he will be insufficiently prepared to solve herd problems, and the Herd is the sum of several animals. We all know that very often one single animal allows us to implement herd strategies and develop prophylactic programs. We are convinced that the veterinary profession, and in our case the Cattle Medicine should have the ability to evolve, otherwise the Veterinarian as we know him will miss the train in the next years.

Educação física e conhecimentos na promoção de estilos de vida ativos

A atividade física e desportiva é fundamental para o desenvolvimento equilibrado dos adolescentes, devendo os hábitos de prática serem adquiridos precocemente, para que façam parte integrante do seu estilo de vida. O estudo teve como objetivo geral caracterizar o estilo de vida dos alunos da Escola Secundária de Silves, relacionando-o com os seus conhecimentos de aptidão física e condição física. A população é composta por 89 alunos que frequentavam o 12º ano da Escola Secundária de Silves, 21 rapazes e 68 raparigas. Os resultados revelam que a maioria dos alunos apresenta uma atitude favorável face às aulas de educação física. Estudando a prática da atividade física e desportiva formal e informal, verificámos que maioritariamente os alunos não acumulam a quantidade de prática diária recomendada, considerando-se pouco ativos ou sedentários, sendo os rapazes mais ativos do que as raparigas. Verificámos grande debilidade dos conhecimentos nas questões relacionadas com as recomendações de prática, benefícios para a saúde associados a um estilo de vida ativo e perigos associados à inatividade física. Não há diferenças significativas entre os conhecimentos dos rapazes e os das raparigas. Não há diferenças significativas entre conhecimentos e estilo de vida. Há uma correlação fraca entre prática da atividade física formal e conhecimentos.

The new professional: underdog or expert? New Museology in the 21th century

For a long time, museum’s form and function were impregnated with social exclusion, only accessible for a prosperous and educated minority. It held the monopoly on the past and therefore in a way on the present and the future. However times have changed and different perspectives on museum practices have been taken. In 1989 the British Peter Vergo mentioned as quoted below, a number of possible museologies, including a ‘new’, and therefore presumably an ‘old’ type of museology: “At the simplest level I would define it, as a state of widespread dissatisfaction with the ‘old’ museology, both within and outside the museum profession; and though the reader may object that such a definition is not merely negative, but circular, I would retort that what is wrong with the ‘old’ museology is that it is too much about museum methods, and too little about purposes of museums; that museology has in the past only frequently been seen, if it has been seen at all, as a theoretical and humanistic discipline.” (Vergo, 1989)

A influência da publicidade na obesidade infantil

A obesidade infantil apresenta-se como uma epidemia que afeta milhares de crianças em todo o Mundo, e a publicidade tem sido apontada por inúmeros autores como sendo a principal causa por este problema global. Ao longo deste estudo, tivemos como objetivo analisar se existe algum efeito da publicidade na obesidade infantil, tendo em conta o estímulo ao consumo de grande variedade de alimentos com alta intensidade calórica, por via das estratégias de marketing. Para enquadrar este estudo, procuramos identificar o papel da publicidade na vida das crianças, nas atividades desenvolvidas nos tempos livres, a influência do estilo de vida nas atividades físicas, e por fim tentar perceber o papel que a publicidade, os tempos livres e o estilo de vida têm na obesidade infantil. A investigação apresenta-se como um estudo de caso exploratório qualitativo, onde foram utilizadas entrevistas estruturadas e não estruturadas individuais, bem como de grupo utilizando a técnica de Focus Grupo num infantário privado no concelho de Cascais. A amostra analisada contou com 12 crianças com idades compreendidas entre os 2 anos e os 5 anos, 10 encarregados de educação, entre eles 3 homens e 7 mulheres com idades compreendidas entre os 27 anos e os 45 anos. Foram incluídas ainda na amostra uma educadora de infância e a directora do infantário, o que permitiu estabelecer uma relação entre as diversas variáveis em estudo. Desta forma, foi possível chegar a resultados que nos indicaram em primeiro lugar, que as crianças nesta faixa etária estão expostas a um número muito elevado de mensagens publicitárias, e que a publicidade já faz parte integrante da sua vida. Percebemos ainda que alguns pais tentam controlar o número de horas de exposição à publicidade, na televisão, bem como os canais visualizados pelos filhos. No entanto não o conseguem, por eles estarem em contato com a publicidade através dos mais variados meios. Verificou-se deste modo que as crianças já conhecem muitas marcas, embalagens e as respectivas mascotes e que por isso solicitam a sua compra. A embalagem reforçou neste estudo a sua importância, uma vez que se apresenta em alguns casos como a grande atração no ponto de venda independentemente do tipo de produto. Relativamente aos tempos livres, existe um padrão de comportamentos onde as crianças praticam mais actividades no verão e aos fins-de-semana devido à disponibilidade dos pais, sendo que no restante período o sedentarismo é muito grande e que a exposição à televisão é muito acentuada. Os factores económicos, sociais e tecnológicos apresentam-se como os principais influenciadores relativamente ao estilo de vida. Como conclusão, consideramos que a obesidade nas crianças é multifacetada e que a publicidade não é o seu principal influenciador, é apenas mais um factor que poderá agravar a situação de muitas crianças quando não têm o devido acompanhamento familiar.

Comunicação nas organizações e tácticas de socialização : o caso dos estagiários de jornalismo televisivo

A presente investigação trata um tema muito discutido hoje em dia nos meios da comunicação social em Portugal, mas que se relaciona com uma problemática mais ampla de comunicação nas organizações: a integração dos estagiários de jornalismo nas estruturas redactoriais. Vários autores como Sara Meireles Graça, Paulo Faustino e José Luís Garcia têm-se debruçado sobre o problema do “corrupio” de jornalistas estagiários nas redacções e sobre outro tema muito controverso, directamente relacionado, que é o “trabalho escravo” no jornalismo (Garcia et. al., 2009, p. 147). Pretendemos aprofundar estas questões, averiguando a sua dimensão e qual o interesse das empresas neste e noutros processos de recrutamento e integração organizacional, assim como o que pensam sobre tudo isto os estagiários e outros intervenientes. O estudo terá como objecto as três estações generalistas de televisão em Portugal. A pesquisa empírica desenvolveu-se nestas três estações de televisão que, salvaguardando as suas particularidades, foram tomadas como organizações-exemplo para a análise dos processos de integração e socialização organizacional. Realizámos um estudo longitudinal com base numa metodologia de cariz qualitativo a partir do olhar, nomeadamente, dos responsáveis pelos estágios nas redacções e dos estagiários, que são os principais atores neste processo. Os resultados apontam para a existência em algumas televisões, de estagiários curriculares a desempenhar funções como se de jornalistas profissionais se tratassem. Em relação a este tema, também existem divergências de opinião entre as entidades que regulam a profissão e as que representam as televisões. Quanto às tácticas de socialização, as televisões conseguem formar profissionais autónomos, apesar da existência de alguns casos de insatisfação e desinvestimento por parte de estagiários.

Escenarios de colonialismo y (de) colonialidad en la construcción del Ser Negro. Apuntes sobre las relaciones de género en comunidades negras del Pacífico colombiano (Tema Central)

Las relaciones de género en las comunidades negras están mediadas por el legado esclavista a la que fue sometida la población afro descendiente en las Américas, éstas se forjaron en la construcción histórica del ser negros. Aun la estructura patriarcal fue una potestad de los amos esclavistas, no del negro despojado de sí mismo, tanto el hombre como la mujer negro-negra esclavos fueron mercancías, su sexualidad y sus relaciones hicieron parte de la función de mercantil que le infringieron los amos, la maternidad fue un oficio y el hombre negro un reproductor de bienes. El derecho a Ser es el primer principio en la propuesta organizativa del Proceso de Comunidades Negras –PCN– como estrategia de dignificación del ser negros y de descolonización interna y externa desde el sujeto mismo hacia y desde la sociedad que le rodea.

Mammal reproductive strategies driven by offspring mortality-size relationships

Trade-offs have long been a major theme in life-history theory, but they have been hard to document. We introduce a new method that reveals patterns of divergent trade-offs after adjusting for the pervasive variation in rate of resource allocation to offspring as a function of body size and lifestyle. Results suggest that preweaning vulnerability to predation has been the major factor determining how female placental mammals allocate production between a few large and many small offspring within a litter and between a few large litters and many small ones within a reproductive season. Artiodactyls, perissodactyls, cetaceans, and pinnipeds, which give birth in the open on land or in the sea, produce a few large offspring, at infrequent intervals, because this increases their chances of escaping predation. Insectivores, fissiped carnivores, lagomorphs, and rodents, whose offspring are protected in burrows or nests, produce large litters of small newborns. Primates, bats, sloths, and anteaters, which carry their young from birth until weaning, produce litters of one or a few offspring because of the need to transport and care for them.

Inulin-type fructans in healthy aging

Worldwide, the population is aging, with estimates of 1 billion people aged 60 y or over within the next 20 y. With aging comes a reduction in overall health and increased morbidity and mortality due to infectious disease. Mortality due to gastrointestinal infections is up to 400 times higher in the elderly compared with younger adults. Recent studies have shown that the gut microbiota changes in old age, with an increased number of bacterial groups represented in the predominant elderly gut microbiota. This change in species "evenness" coincides with parallel changes in immune function, diet, and lifestyle and may contribute to disease susceptibility and severity in old age. The intestinal microbiota may thus be identified as an important target for improving health through reduced disease risk. Here, the application of prebiotics, especially the inulin-type fructans, and synbiotics (prebiotics combined with efficacious probiotic strains) will be discussed in terms of microbiota modulation and impact on disease risk in the aged population. Recent human intervention studies have confirmed the microbiota modulatory capability of the inulin-type fructans in the elderly and there is some evidence for reduced risk of disease. However, there is a need for more and larger human intervention studies to determine the efficacy of prebiotics in the elderly, particularly studies that take advantage of recent high resolution analytical methodologies like metabonomics, to shed light on possible prebiotic mechanisms of action.

The acceptability of isoflavones as a treatment of menopausal symptoms: a European survey among postmenopausal women

Objective: To investigate determinants of the acceptability of isoflavone products among postmenopausal women with regard to social and lifestyle factors, dietary habits, health concerns, food beliefs, menopausal symptoms and therapies, and to elucidate preferences for specific products. Methods: A consumer survey was conducted among postmenopausal women in four European countries (Germany, Denmark, Italy and the UK), including a total of 465 respondents. Results: The declared acceptability of isoflavones was highest in Germany (80%), followed by Italy (75%), the UK (59%) and Denmark (55%; p < 0.001). Among other factors, prior information about isoflavones (odds ratio (OR) 2.64, 95% confidence interval (CI) 1.54-4.51, p < 0.001) and belief that foods can be used to treat medical conditions (OR 2.18, 95% CI 1.17-4.05, p=0.014) were the strongest predictors of potential acceptability. The preferred forms in which isoflavones might be taken differed markedly between countries. Conclusions: Information about the health effects of isoflavones and health-diet links should be considered the most important factors in attempts to influence the potential acceptability of isoflavone products. Foods enriched with isoflavones need to be developed with regard to specific cultural demands in order to assure consumer acceptance on the marketplace.

The impact of substituting SFA in dairy products with MUFA or PUFA on CVD risk: evidence from human intervention studies

With the substantial economic and social burden of CVD, the need to modify diet and lifestyle factors to reduce risk has become increasingly important. Milk and dairy products, being one of the main contributors to SFA intake in the UK, are a potential target for dietary SFA reduction. Supplementation of the dairy cow's diet with a source of MUFA or PUFA may have beneficial effects on consumers' CVD risk by partially replacing milk SFA, thus reducing entry of SFA into the food chain. A total of nine chronic human intervention studies have used dairy products, modified through bovine feeding, to establish their effect on CVD risk markers. Of these studies, the majority utilised modified butter as their primary test product and used changes in blood cholesterol concentrations as their main risk marker. Of the eight studies that measured blood cholesterol, four reported a significant reduction in total and LDL-cholesterol (LDL-C) following chronic consumption of modified milk and dairy products. Data from one study suggested that a significant reduction in LDL-C could be achieved in both the healthy and hypercholesterolaemic population. Thus, evidence from these studies suggests that consumption of milk and dairy products with modified fatty acid composition, compared with milk and dairy products of typical milk fat composition, may be beneficial to CVD risk in healthy and hypercholesterolaemic individuals. However, current evidence is insufficient and further work is needed to investigate the complex role of milk and cheese in CVD risk and explore the use of novel markers of CVD risk.

‘Purpose’ as a way of helping white trainee history teachers engage with diversity issues

Based on a three year action research project, this study examines one strand of that research, namely the impact that ‘purpose’, i.e. exploring the range of rationales for studying a subject, has in helping white trainee teachers embrace cultural and ethnic diversity within their teaching. Through ‘purpose’ trainees explored different reasons why history should be taught (and by implication what content should be taught and how it should be taught) and the relationship of these reasons to diversity. Focusing on ‘purpose’ appears to have a positive impact on many trainees from white, mono-ethnic backgrounds, enabling them to bring diversity into the school curriculum, in this case history teaching. It offers one way to counter concerns about issues of ‘whiteness’ in the teaching profession and by teaching a more relevant curriculum has a potential positive impact on the achievement of students from minority ethnic backgrounds.

One size fits all: the increasing standardisation of English teachers' work in England

English teachers in England have experienced a lengthy period of external constraint, increasingly controlling their practice. This constraint was originated in the 1989 National curriculum. Although in its first version it was in harmony with practice, its numerous revisions have moved it a long way from teachers’ own values and beliefs. This move is illustrated through research into the teaching of literature, which is seen by English teachers as often arid and driven by examinations alone. This period has been increasingly dominated by high-stakes testing, school league tables and frequent school inspections. Another powerful element has been the introduction of Standards for teachers at every career level from student teachers to the Advanced Skills Teachers. Research demonstrates that this introduction of Standards has had some beneficial effects. However, research also shows that the government decision to replace all these, hierarchically structured standards, with a single standard is seen by many teachers as a retrograde step. Evidence from Advanced Skills Teachers of English shows that the government’s additional proposal to bring in a Master Teacher standard is equally problematic. The decline of the National Association for the Teaching of English, the key subject association for English teachers, is discussed in relation to this increasingly negative and constraining environment, concluding that many English teachers are choosing a form of local resistance which, while understandable, weakens the credibility of the profession and erodes the influence of its key voice, NATE.

An insight into the public acceptance of nutrigenomic-based personalised nutrition.

It is predicted that non-communicable diseases will account for over 73 % of global mortality in 2020. Given that the majority of these deaths occur in developed countries such as the UK, and that up to 80 % of chronic disease could be prevented through improvements in diet and lifestyle, it is imperative that dietary guidelines and disease prevention strategies are reviewed in order to improve their efficacy. Since the completion of the human genome project our understanding of complex interactions between environmental factors such as diet and genes has progressed considerably, as has the potential to individualise diets using dietary, phenotypic and genotypic data. Thus, there is an ambition for dietary interventions to move away from population-based guidance towards 'personalised nutrition'. The present paper reviews current evidence for the public acceptance of genetic testing and personalised nutrition in disease prevention. Health and clear consumer benefits have been identified as key motivators in the uptake of genetic testing, with individuals reporting personal experience of disease, such as those with specific symptoms, being more willing to undergo genetic testing for the purpose of personalised nutrition. This greater perceived susceptibility to disease may also improve motivation to change behaviour which is a key barrier in the success of any nutrition intervention. Several consumer concerns have been identified in the literature which should be addressed before the introduction of a nutrigenomic-based personalised nutrition service. Future research should focus on the efficacy and implementation of nutrigenomic-based personalised nutrition.
