Incident cancer burden attributable to excess body mass index in 30 European countries

Excess adiposity is associated with increased risks of developing adult malignancies. To inform public health policy and guide further research, the incident cancer burden attributable to excess body mass index (BMI >or= 25 kg/m(2)) across 30 European countries were estimated. Population attributable risks (PARs) were calculated using European- and gender-specific risk estimates from a published meta-analysis and gender-specific mean BMI estimates from a World Health Organization Global Infobase. Country-specific numbers of new cancers were derived from Globocan2002. A ten-year lag-period between risk exposure and cancer incidence was assumed and 95% confidence intervals (CI) were estimated in Monte Carlo simulations. In 2002, there were 2,171,351 new all cancer diagnoses in the 30 countries of Europe. Estimated PARs were 2.5% (95% CI 1.5-3.6%) in men and 4.1% (2.3-5.9%) in women. These collectively corresponded to 70,288 (95% CI 40,069-100,668) new cases. Sensitivity analyses revealed estimates were most influenced by the assumed shape of the BMI distribution in the population and cancer-specific risk estimates. In a scenario analysis of a plausible contemporary (2008) population, the estimated PARs increased to 3.2% (2.1-4.3%) and 8.6% (5.6-11.5%), respectively, in men and women. Endometrial, post-menopausal breast and colorectal cancers accounted for 65% of these cancers. This analysis quantifies the burden of incident cancers attributable to excess BMI in Europe. The estimates reported here provide a baseline for future modelling, and underline the need for research into interventions to control weight in the context of endometrial, breast and colorectal cancer.

Secado de ajo elefante : allium ampeloprasum

Los estudios realizados en la Argentina sobre poscosecha del género Allium se refieren a A. sativum, no habiéndolos sobre Allium ampeloprasum (ajo elefante), de buenas características organolépticas (sabor más suave) y creciente demanda en los mercados internos y externos. Por tal motivo se decidió investigar la incidencia del método de secado en su pérdida de peso comparando el procedimiento tradicional en caballete con el realizado en horno solar con circulación forzada de aire. En ambos casos se efectuaron 5 repeticiones para control de pérdida de peso. Se sacaron muestras al azar de los distintos niveles de las paseras para establecer la humedad en bulbo entero, bulbo pelado y hojas, efectuando 3 repeticiones para cada determinación y tratamiento. La duración de los tratamientos se determinó en base a la humedad en hoja y bulbo entero, puesto que la variación en bulbo pelado no fue significativa. Los datos fueron evaluados con el análisis de la varianza utilizando un nivel de significancia del 5 % y la prueba de Duncan. En las condiciones del ensayo, el secado en horno solar adelanta 6 días la terminación, con una pérdida de peso del 30,7 %.

Planeamento e controlo dos custos da qualidade nas empresas certificadas

A presente dissertação aborda a importância do planeamento e controlo dos custos da qualidade para a gestão da qualidade, postura fundamental na estratégia das organizações, que procuram vantagens competitivas para assegurarem a sua continuidade num mundo globalizado. Apesar do movimento da qualidade estar intimamente associado à certificação dos sistemas de gestão da qualidade, os mesmos, por si só, não são suficientes para assegurar a competitividade das organizações nos mercados altamente competitivos. Hoje em dia, as empresas dispõem, regra geral, de menos recursos do que no passado, o que as obriga a geri-los de forma mais criteriosa e racional. Assim, as organizações, cada vez mais, têm que ser eficientes na sua gestão e procuram medir a qualidade em termos monetários, através de sistemas de gestão de custos da qualidade, destacando assim a validade e utilidade do planeamento e controlo dos custos da qualidade, como instrumento de gestão. Assim sendo, este estudo apresenta como objetivo principal conhecer os procedimentos adotados no planeamento e controlo dos custos da qualidade nas empresas portuguesas certificadas, bem como verificar se elaboram relatórios de gestão que permitam determinar o retomo financeiro dos investimentos efetuados em qualidade. Os resultados obtidos evidenciam uma reduzida adesão da maioria das empresas respondentes em relação à implementação de sistemas formais, que quantificam e controlam os custos de qualidade, bem como à identificação explícita e isolada dos custos da qualidade nos relatórios de gestão. Também ficou averiguado o baixo nível de controlo dos investimentos efetuados em qualidade e, evidentemente, tal procedimento acarreta dificuldades na quantificação dos retornos obtidos nas empresas portuguesas certificadas. ABSTRACT: The present dissertation approaches the importance of planning and control quality costs for the management of quality, a key element for the strategy of the organizations that seek out competitive advantages to assure the continuity in a globalized world. Despite of the movement of the quality being intimately associated to the certification of the quality management systems, they are not enough to assure the competitiveness of organizations in highly competitive markets. Presently, organizations are facing a reduction in the amount of available resources, forcing them to manage those resources in a more discerning and rational way. More and more, the organizations have to be efficient and attempt to measure the quality in financial terms, through cost of quality management systems, thus showing the validity and usefulness of planning and control the costs of quality as a management instrument. ln this way, the main purpose of the study is to know the practices adopted by certified Portuguese companies concerning to the planning and control of quality costs, as well as to know if those companies are preparing management reports that allow them to verify the financial return of the investments in quality. The results showed that only a few number of the inquired companies have implemented formal systems that quantify and control the quality costs, and identify in an explicit and segregate way the quality costs in management reports. The results also showed the low level of control related to the investments in quality and the resultant problems in quantifying the returns of quality investments by the certified Portuguese companies.

A Formação de Oficiais de Administração: Especificidades, Oportunidades e Contingências na senda de uma Carreira Profissional

Face ao paradigma atual onde são constantemente impostas às entidades públicas medidas para a racionalização de recursos, os Estabelecimentos de Ensino Superior Público Universitário Militar não são exceção tornando-se cada vez mais premente a aposta numa gestão eficiente e eficaz. Neste âmbito, a Contabilidade Analítica assume de forma crescente um papel dominante na análise e controlo dos custos por atividade. O presente Trabalho de Investigação Aplicada encontra-se subordinado ao tema “A Formação de Oficiais de Administração: Oportunidades, Especificidades e Contingências na senda de uma Carreira Profissional”. Assim, o objetivo geral do presente trabalho passa pelo cálculo do custos de formação dos alunos de Administração dos três ramos das Forças Armadas e desta forma, optar pelo modelo mais rentável economicamente. Para o cálculo do custo, de entre as inúmeras opções existentes relativamente a sistemas de custeio, baseámo-nos no método das Secções Homogéneas ou Centros de Custos. A estrutura do trabalho pode ser dividida em duas partes, a primeira de cariz teórico e a segunda uma vertente prática. A metodologia adotada teve como referência o método de investigação em Ciência Sociais, isto é, partindo de uma pergunta central de investigação, que origina perguntas derivadas, procuram-se respostas através da formulação, exploração e teste de hipóteses. De acordo com os resultados do presente estudo podemos verificar que é o modelo de formação utilizada na Academia Militar o mais rentável economicamente. Desta forma, dadas as evidentes afinidades científicas existentes entre os cursos seria pertinente uma reconfiguração da estrutura científica, durações e do perfil formativo dos diferentes cursos. Assim, uma reorganização que elimine redundâncias e promova a partilha de recursos possibilitará ganhos de eficiência na gestão e consequentemente redução de custos.

Salt promotes passive overconsumption of dietary fat in humans

BACKGROUND: Excess fat consumption has been linked to the development of obesity. Fat and salt are a common and appetitive combination in food; however, the effect of either on food intake is unclear. Fat taste sensitivity has been negatively associated with dietary fat intake, but how fat taste sensitivity influences the intake of fat within a meal has, to our knowledge, not yet been investigated.

OBJECTIVES: Our objectives were, first, to investigate the effects of both fat and salt on ad libitum food intake and, second, to investigate the effects of fat taste sensitivity on satiation responses to fat and whether this was affected by salt.

METHODS: Forty-eight healthy adults [16 men and 32 women, aged 18-54 y, body mass index (kg/m(2)): 17.8-34.4] were recruited and their fat taste sensitivity was measured by determination of the detection threshold of oleic acid (18:1n-6). In a randomized 2 × 2 crossover design, participants attended 4 lunchtime sessions after a standardized breakfast. Meals consisted of elbow macaroni (56%) with sauce (44%); sauces were manipulated to be1) low-fat (0.02% fat, wt:wt)/low-salt (0.06% NaCl, wt:wt),2) low-fat/high-salt (0.5% NaCl, wt:wt),3) high-fat (34% fat, wt:/wt)/low-salt, or4) high-fat/high-salt. Ad libitum intake (primary outcome) and eating rate, pleasantness, and subjective ratings of hunger and fullness (secondary outcomes) were measured.

RESULTS: Salt increased food and energy intakes by 11%, independent of fat concentration (P= 0.022). There was no effect of fat on food intake (P= 0.6), but high-fat meals increased energy intake by 60% (P< 0.001). A sex × fat interaction was found (P= 0.006), with women consuming 15% less by weight of the high-fat meals than the low-fat meals. Fat taste sensitivity was negatively associated with the intake of high-fat meals but only in the presence of low salt (fat taste × salt interaction on delta intake of high-fat - low-fat meals;P= 0.012).

CONCLUSIONS: The results suggest that salt promotes passive overconsumption of energy in adults and that salt may override fat-mediated satiation in individuals who are sensitive to the taste of fat.

Implementação da contabilidade analítica no Instituto Politécnico de Beja

A opção por uma gestão eficiente e eficaz é a resposta a dar à crescente racionalização de recursos que tem vindo a ser imposta às entidades públicas portuguesas e à qual não escapam as instituições que integram o sector do ensino superior. Assim sendo, estas entidades devem desenvolver e ao mesmo tempo, adoptar mecanismos que lhes permitam gerir recursos, quer os colocados à sua disposição, quer os gerados internamente, tendo em vista a sua optimização. Actualmente a prática da Contabilidade Analítica nas Instituições assume, cada vez mais, um papel dominante na análise e controlo dos custos, mas também dos proveitos e resultados por actividade. O objectivo da implementação deste Projecto, além de ser um desafio pessoal e Institucional, é uma obrigação legislativa, à qual pretendemos responder ao colocarmos em prática a Contabilidade Analítica, inserida no Plano Oficial de Contabilidade para o Sector Público - Sector da Educação, aprovado pela Portaria nº 794/2000, de 20 de Setembro. ABSTRACT: The choice of an efficient and effective management is the answer to the increasing rationalization of resources that have been imposed on portuguese public entities and of which the institutions from the higher education sector do not escape. Therefore, these entities must develop, and at the same time, adopt mechanisms that allow them to manage resources, both those placed at their disposal, and those that are internally generated, with an aim of optimization. Currently the practice of management accounting in the institutions assumes an increasingly a dominant role in the analysis and control of costs, but also in the income and earnings per activity. The purpose of implementing this project, besides being a personal and institutional challenge, is a legislative requirement that must be dealt with, by putting into practice the Management Accounting, inserted in the Official Accounting Plan for the Public Sector- Education Sector, approved by the Ordinance Nº 794/2000 of September 20.

Self-referencing and consumer evaluations of larger-sized female models : a weight locus of control perspective

In two experiments, we show that the beliefs women have about the controllability of their weight (i.e., weight locus of control) influences their responses to advertisements featuring a larger-sized female model or a slim female model. Further, we examine self-referencing as a mechanism for these effects. Specifically, people who believe they can control their weight (“internals”), respond most favorably to slim models in advertising, and this favorable response is mediated by self-referencing. In contrast, people who feel powerless about their weight (“externals”), self-reference larger-sized models, but only prefer larger-sized models when the advertisement is for a non-fattening product. For fattening products, they exhibit a similar preference for larger-sized models and slim models. Together, these experiments shed light on the effect of model body size and the role of weight locus of control in influencing consumer attitudes.

Liking vs. wanting food : importance for human appetite control and weight regulation

Current train of thought in appetite research is favouring an interest in non-homeostatic or hedonic (reward) mechanisms in relation to overconsumption and energy balance. This tendency is supported by advances in neurobiology that precede the emergence of a new conceptual approach to reward where affect and motivation (liking and wanting) can be seen as the major force in guiding human eating behaviour. In this review, current progress in applying processes of liking and wanting to the study of human appetite are examined by discussing the following issues: How can these concepts be operationalised for use in human research to reflect the neural mechanisms by which they may be influenced? Do liking and wanting operate independently to produce functionally significant changes in behaviour? Can liking and wanting be truly experimentally separated or will an expression of one inevitably contain elements of the other? The review contains a re-examination of selected human appetite research before exploring more recent methodological approaches to the study of liking and wanting in appetite control. In addition, some theoretical developments are described in four diverse models that may enhance current understanding of the role of these processes in guiding ingestive behaviour. Finally, the implications of a dual process modulation of food reward for weight gain and obesity are discussed. The review concludes that processes of liking and wanting are likely to have independent roles in characterising susceptibility to weight gain. Further research into the dissociation of liking and wanting through implicit and explicit levels of processing would help to disclose the relative importance of these components of reward for appetite control and weight regulation.

Overeating as a clue to weight gain: behavioural and physiological interactions in the control of food intake

It has been estimated that 25-50% of people in most affluent societies are either obese or overweight. These disorders are the result of an imbalance between calorific intake and energy expenditure over a prolonged time period. These types of disorders are among the most common health problems in industrialized societies. Addressing these issues and offering new strategies, this thorough new study draws together contributions from interdisciplinary and international group of specialists, includes recent research on genetic influences, features discussions of epidemiological studies and covers both biological and social aspects of obesity.

Acute and long-term effects of exercise on appetite control: Is there any benefit for weight control?

Purpose of review: To examine the relationship between energy intake, appetite control and exercise, with particular reference to longer term exercise studies. This approach is necessary when exploring the benefits of exercise for weight control, as changes in body weight and energy intake are variable and reflect diversity in weight loss. Recent findings: Recent evidence indicates that longer term exercise is characterized by a highly variable response in eating behaviour. Individuals display susceptibility or resistance to exercise-induced weight loss, with changes in energy intake playing a key role in determining the degree of weight loss achieved. Marked differences in hunger and energy intake exist between those who are capable of tolerating periods of exercise-induced energy deficit, and those who are not. Exercise-induced weight loss can increase the orexigenic drive in the fasted state, but for some this is offset by improved postprandial satiety signalling. Summary: The biological and behavioural responses to acute and long-term exercise are highly variable, and these responses interact to determine the propensity for weight change. For some people, long-term exercise stimulates compensatory increases in energy intake that attenuate weight loss. However, favourable changes in body composition and health markers still exist in the absence of weight loss. The physiological mechanisms that confer susceptibility to compensatory overconsumption still need to be determined.

How do consumers react to physically larger models? Effects of model body size, weight control beliefs and product type on evaluations and body perceptions

The purpose of this article is to examine how a consumer’s weight control beliefs (WCB), a female advertising model’s body size (slim or large) and product type influence consumer evaluations and consumer body perceptions. The study uses an experiment of 371 consumers. The design of the experiment was a 2 (weight control belief: internal, external) X 2 (model size: larger sized, slim) X 2 (product type: weight controlling, non-weight controlling) between-participants factorial design. Results reveal two key contributions. First, larger sized models result in consumers feeling less pressure from society to be thin, viewing their actual shape as slimmer relative to viewing a slim model and wanting a thinner ideal body shape. Slim models result in the opposite effects. Second this research reveals a boundary condition for the extent to which endorser–product congruency theory can be generalized to endorsers of a larger body size. Results indicate that consumer WCB may be a useful variable to consider when marketers consider the use of larger models in advertising.
