Objective Results of the WHO European Childhood Obesity Surveillance Initiative indicated that on average one out of four primary-school children is overweight or obese. Portugal presented one of the highest prevalences of obesity. Childhood obesity prevention and treatment should be a top priority. The aim of the present study was to evaluate the effectiveness of Program Obesity Zero (POZ), a multi-component, community-, family- and school-based childhood obesity intervention. Design Parents and children attended four individual nutrition and physical activity counselling sessions, a one-day healthy cooking workshop and two school extracurricular sessions of nutrition education. Waist circumference, BMI, physical activity level, sedentary behaviours, and nutrition and physical activity knowledge, attitudes and behaviour were assessed at baseline and after 6 months. Diet was assessed using two 24 h recalls, at baseline and at 6 months. Setting Five Portuguese municipalities and local communities. Subjects Two hundred and sixty-six overweight children (BMI ≥ 85th percentile) aged 6-10 years, from low-income families in five Portuguese municipalities, were assigned to the intervention. Results Children showed reductions in waist circumference (-2·0 cm; P < 0·0001), mean BMI (-0·7 kg/m2; P < 0·0001) and BMI-for-age percentile (-1·7; P < 0·0001) at 6 months. Overall, children's intake of fruit and vegetables was <400 g/d throughout the intervention. After 6 months, higher fibre consumption and an apparent decrease in sugary soft drinks intake to a quarter of that observed at baseline (mean intake: 198 ml/d at baseline), with improvements in physical activity levels and screen time <2 h/d, were also observed. Conclusions The findings suggested that POZ is a promising intervention programme, at municipality level, to tackle childhood overweight and obesity. Copyright © The Authors 2013.

KEOD 2012 - Proceedings of the International Conference on Knowledge Engineering and Ontology Development | Year: 2012
Ontologies have been used to support both web agents reasoning and human decision making. However, ontology development is a new area and for some knowledge domains they are still rare. Although ontologies had been developed in the context of Semantic Web, it is the Web 2.0 content that is actually pervasive on the web. One of the properties of this content is to be multilingual, which requires multilingual resources to deal with it. Online reviews are examples of multilingual texts provided by products and services consumers. This paper presents a multilingual ontology for the accommodation sector. As a result, we deliver Hontology, a freely available domain-specific ontology. Hontology reuses concepts of other vocabularies such as Dbpedia.org and Schema.org. It is useful for a wide range of applications within the accommodation sector, including ontology-based information extraction, text annotation and information visualisation.

In recent years, the research in the area of ubiquitous healthcare has intensified. There are many technological advances regarding the development of unobtrusive sensors for cardiac and respiratory activity, but the current scenario is still far away from an everyday life fulfilled with ubiquitous healthcare systems. In this paper, it is described the usage of 24GHz microwave FMCW (frequency modulated continuous wave) Doppler radar (MDR) as one of the main components of a pervasive biomedical system that is part of an assistive environment for the people with less mobility or people with long term health condition. As parts of the present work, in this paper are mentioned the design and implementation of an assistive environment based on a MDR sensor, an experimental study concerning the microwave Doppler radar characteristics and remote sensing of heart rate and breath rate, based on acquisition and processing of the signals delivered by the used radar. ©2010 IEEE.

Ecology of Freshwater Fish | Year: 2010
Knowledge of patterns of refuge use by fish is critical for maintaining biodiversity in drought-prone streams. In this study, the fish assemblages of 21 dry-season pools in a Mediterranean stream were characterised and related to three sets of factors reflecting pool morphology, physicochemistry and spatial context. Fish were associated with the three sets of variables, with variation partitioning indicating that overall species richness and abundance were primarily related to pool morphology but relative species abundances were mainly associated with physicochemical contexts. In general, species richness was the highest but overall fish abundance was the lowest in large pools. Pools well shaded by riparian canopy held the highest richness and abundance of native fish, but relative species abundances and assembly structure varied among pools contingent on canopy cover, substrate composition and spatial location. These results suggested that conservation of fish diversity in Mediterranean streams requires networks of pools with diverse sizes and physicochemical contexts. © 2009 John Wiley & Sons A/S.

The positioning of a website in the first places of the rankings produced by the search engines makes it more visible to the eyes of Internet users, which is a clear competitive advantage over competing websites. In order to be able to achieve this competitive advantage it's important to perform a web site optimization towards being easily located and highly rated by search engines. This article identifies some of the main optimization techniques, and is based on the action research method to provide evidence that the positive evolution of some indicators, namely, the number of visits, internet traffic and better web site placement in SERP (Search Engine Results Page) resulted, in part, from the application of these optimization techniques to a vehicle auction website in Portugal. © 2014 AISTI.

Jacques Ellul's thoughts on the increasingly conspicuous role of persuasion techniques bring to the fore the persuasive and normative effects of new communication techniques at the core of contemporary consumer/citizen culture, as well as the limits of that instrumental stance towards mediated human communication. By drawing insights from authors who shared some of Ellul's concerns, such as Frankfurt School theorists, Vance Packard and Ivan Illich, this paper explores this "normative invasion" of human life by technique as a feature of contemporary information technology politics, specifically in (1) the historical context of normative and material technological colonization, and (2) the intertwining of propaganda and information warfare in the current reshaping of information politics.

In this paper Heart Rate Variability (HRV) and Blood Pressure Variability (BPV) were analyzed before the onset of cardiac arrhythmia in order to derive markers for short-term forecasting. The (a) coherence between systolic blood pressure (SBP) and cardiac oscillations in low-frequency (LF) and high-frequency (HF) band; (b) fluctuations of phase; (c) HRV and BPV as a LF power and HF power in frequency and time-frequency domain; (d) transfer function analysis of cardiovascular signals were analyzed. Arrhythmia was preceded by: a) lower coherence; b) increase in fluctuations of phase between signals; c) higher spectral energy associated with respiratory frequency in blood pressure signal; d) raise of sympathetic outflow to the heart; e) decreased HRV. Cardiac arrhythmia was characterized mainly by an increase in LF power of blood pressure, cardiac signal and transfer function. During self-termination of arrhythmia a larger increased in total BPV and HRV was recorded. These results suggest that important information about both neuronal cardiovascular control and risk for spontaneous arrhythmia can be provided by combined analysis of frequency, phase, and time-frequency analysis of blood pressure and cardiac oscillation.

The technological evolution allows us to have highly flexible solutions, easily accessible with lower investment values, which leads to many companies adopting SaaS (Software as a Service) to support their business processes. Nowadays, almost all of the IT strategies decision-makers in organizations are encouraged to consider the adoption of SaaS as an IT solution, because of the benefits of convenience associated with technology or market competition. Very often business strategies decision-makers only consider the attractive incentives of SaaS and they ignore the impacts associated with new technologies. A holistic view of the implications in the development, in the supply, in the use and in the operation of SaaS in different types of business organizations is necessary. © 2016 AISTI.

Purpose-This chapter examines and illustrates the judicial treatment of relevant concepts and norms of corporate sustainability and relevant implications for the implementation of the UN Global Compact. Methodology/approach-This is a conceptual examination of relevant legislation, cases and concepts used by judges in giving practical content to the concepts of 'sustainable development', 'sustainability' and 'corporate sustainability'. Findings-The judiciary has been fashioning applicable policy, resolving and balancing the clash of interests, setting guidelines and parameters for statutory interpretation in elucidating the concept of corporate sustainability. To that extent 'corporate sustainability law' is developing, not only in municipal public law where legislation is the key driver, but as 'soft' international law. Research limitations/implications-This is a general survey of trends in judicial reasoning from different countries and legal traditions and is not applicable exclusively to any jurisdiction. The implication is that there is room for detailed study of applicable rules in each jurisdiction. Practical implications-The chapter offers guidance for strategic implementation of the Global Compact, compliance to emergent obligatory principles, for shaping policy and corporate political management. Originality/value-This chapter contributes to an understanding of the role and impact of the judiciary in developing corporate sustainability law and congruent principles of the Global Compact.
