Strategic Drivers for Implementing Sustainability Programs in Portuguese Organizations– Let’s Listen to Aristotle: From Triple to Quadruple Bottom Line

This article describes a study that investigated the main strategic drivers that influence the implementation of sustainability/social responsibility programs. An online survey was administered to managers of Portuguese organizations with certified management systems. The findings suggest that the implementation of such programs is mainly correlated to: 1.) the approach to understanding and working toward the satisfaction of the community’s needs (in the broad sense of social responsibility); 2.) how systematically sustainability within the organization is identified and managed (e.g., pollution prevention, improved environmental performance, and compliance with the applicable environmental laws); and 3.) the degree to which the organization tries to understand the needs of the employees and works toward satisfying them. In addition to the survey, five interviews with top managers of the surveyed organizations provided some useful insights. There was no consensus on the meaning of sustainability and social responsibility: some described it as an instrumental approach for obtaining better organizational results, while others regarded it as the right thing to do (i.e., it is values driven). In all cases, however, the managers supported a kind of umbrella construct under which different size corporations use different models (for example, the Dow Jones Sustainability Index (DJSI), Global Reporting Initiative (GRI), ISO 14001 environmental management systems), although some managers reported that they simply do not know what to do. All of those surveyed agreed that the lack of a systematic approach could represent a major threat to their organization, making them willing to pay more attention and take more action on the issue of sustainability. An additional suggestion made by managers was to change from a triple bottom line (economic dimension, environmental dimension, social equity dimension) to a quadruple bottom line by adding another dimension: personal and family happiness. This fourth dimension was recognized by the Greek philosopher/thinker Aristotle (384-322 BCE) who thought of happiness as the highest good (virtue) and ultimate goal and purpose of life, achieved through living well, in harmony. Such harmony suggests a balance and a lack of excess—in other words a sustainable existence.

Leptospirosis severity may be associated with the intensity of humoral immune response

Leptospirosis severity may be increasing, with pulmonary involvement becoming more frequent. Does this increase result from an intense immune response to leptospire? Notice that renal failure, thrombocytopenia and pulmonary complications are found during the immune phase. Thirty-five hospitalized patients with Weil's disease had 5 blood samples drawn, from the 15th day to the 12th month of symptoms, for ELISA-IgM, -IgG and -IgA specific antibody detection. According their 1st IgG titer, the patients were divided into: group 1 (n = 13) titer > 1:400 (positive) and group 2 (n = 22) titer <=1:400 (negative). Early IgG antibodies in group 1 showed high avidity which may indicate reinfection. Group 1 was older, had worse pulmonary and renal function, and fever for a longer period than group 2. Throughout the study, IgG and IgA titers remained higher in group 1. In conclusion, the severity of Weil's disease may be associated with the intensity of the humoral immune response to leptospire.

Stackelberg leadership with demand uncertainty in a differentiated duopoly

On a symmetric differentiated Stackelberg duopoly model in which there is asymmetric demand information owned by leading and follower firms, we show that the leading firm does not necessarily have advantage over the following one. The reason for this is that the second mover can adjust its output level after observing the realized demand, while the first mover chooses its output level only with the knowledge of demand distribution.

Quantity-setting competition under uncertain demand

We consider a quantity-setting duopoly model, and we study the decision to move first or second, by assuming that. the firms produce homogeneous goods and that. there is some demand uncertainty. The competitive phase consists of two periods, and in either period, the firms can make a production decision that is irreversible. As far as the firms are allowed to choose (non-cooperatively) the period they make the decision, we study the circumstances that favour sequential rather than simultaneous decisions.

25 anos de Inquérito Nacional de Saúde em Portug

RESUMO - O Inquérito Nacional de Saúde é um instrumento de observação em saúde promovido pelo Ministério da Saúde desde 1987, em resposta às necessidades crescentes de informação de saúde ligadas ao estabelecimento e às exigências de planeamento e avaliação decorrentes da instituição do Serviço Nacional de Saúde. O Inquérito Nacional de Saúde conta, até agora, com quatro edições. Os dados provêm através do estudo transversal de amostras probabilísticas da população portuguesa, através de entrevistas no domicílio, utilizando instrumentos e métodos válidos e estáveis. Os indicadores gerados descrevem o estado de saúde, utilização de cuidados de saúde e determinantes de saúde da população portuguesa residente em unidades de alojamento familiar e tem representatividade a nível nacional e regional. Além de útil para a investigação dos padrões e tendências na área da saúde da população, esta informação é importante como elemento de planeamento, na identificação de necessidades em saúde e na avaliação dos eventuais efeitos e impactes das intervenções realizadas na saúde da população. A evolução do Inquérito Nacional de Saúde depende da definição das necessidades de informação epidemiológica por parte do Estado e da sua integração no sistema europeu de inquéritos de saúde. --------------------------ABSTRACT – The National Health Interview Survey is an instrument of observation in health promoted by the Ministry of Health since 1987, in response to the growing demand for health information, derived from the institution of the National Health Service, as well as its planning and evaluation activities. The National Health Interview Survey has had four editions so far. Data are obtained through the cross-sectional study of probabilistic samples of the Portuguese population, through interviews at home, using valid and stable instruments and methods. Obtained indicators describe the state of health, use of health care and health determinants of the Portuguese population living in familiar dwellings, and are representative at national and regional levels. Besides its usefulness for the study of patterns and trends, this information is important for planning purposes, in the identification of health needs and for the evaluation of the eventual effects of the planned health interventions. The future of the National Health Interview Survey depends on the State’s definition of the needs of epidemiological information and also on its participation in the European system of health surveys.

Microcystin-LR detection in water by the Fabry–Pérot interferometer using an optical fibre coated with a sol–gel imprinted sensing membrane

Cyanobacteria deteriorate the water quality and are responsible for emerging outbreaks and epidemics causing harmful diseases in Humans and animals because of their toxins. Microcystin-LR (MCT) is one of the most relevant cyanotoxin, being the most widely studied hepatotoxin. For safety purposes, the World Health Organization recommends a maximum value of 1 μg L−1 of MCT in drinking water. Therefore, there is a great demand for remote and real-time sensing techniques to detect and quantify MCT. In this work a Fabry–Pérot sensing probe based on an optical fibre tip coated with a MCT selective thin film is presented. The membranes were developed by imprinting MCT in a sol–gel matrix that was applied over the tip of the fibre by dip coating. The imprinting effect was obtained by curing the sol–gel membrane, prepared with (3-aminopropyl) trimethoxysilane (APTMS), diphenyl-dimethoxysilane (DPDMS), tetraethoxysilane (TEOS), in the presence of MCT. The imprinting effect was tested by preparing a similar membrane without template. In general, the fibre Fabry–Pérot with a Molecular Imprinted Polymer (MIP) sensor showed low thermal effect, thus avoiding the need of temperature control in field applications. It presented a linear response to MCT concentration within 0.3–1.4 μg L−1 with a sensitivity of −12.4 ± 0.7 nm L μg−1. The corresponding Non-Imprinted Polymer (NIP) displayed linear behaviour for the same MCT concentration range, but with much less sensitivity, of −5.9 ± 0.2 nm L μg−1. The method shows excellent selectivity for MCT against other species co-existing with the analyte in environmental waters. It was successfully applied to the determination of MCT in contaminated samples. The main advantages of the proposed optical sensor include high sensitivity and specificity, low-cost, robustness, easy preparation and preservation.

Caracterização da utilização da urgência pediátrica num hospital da área metropolitana de Lisboa

RESUMO - Introdução: Actualmente o uso excessivo dos serviços de Urgência Pediátrica hospitalares constitui uma das preocupações de gestores e administradores hospitalares. Esta má utilização pode contribuir para o aumento descomedido dos custos uma vez que a procura não é adequada para este tipo de serviço. A procura de respostas rápidas aos problemas de saúde contribui para a afluência exagerada e por vezes injustificada por parte da população. Objectivo: O objectivo deste estudo foi efectuar a caracterização da utilização da urgência pediátrica num hospital da área metropolitana de Lisboa, no sentido de compreender se existe, ou não, procura injustificada de cuidados de saúde. Material e métodos: Foi utilizado como suporte metodológico uma abordagem quantitativa, num estudo descritivo - correlacional. Foram analisados 36932 episódios de Urgência Pediátrica ocorridos num período de 6 meses (Julho 2010 a Janeiro 2011). Resultados: A amostra é constituída por 53,6% utentes do sexo masculino e por 46,4% do sexo feminino; onde o intervalo de idades mais representativo situa-se entre o 1 ano e 5 anos de idade. O concelho de Sintra apresenta 61% dos episódios, no entanto proporcionalmente o concelho de Amadora recorre mais à Urgência Pediátrica com 7,48% dos episódios. O dia com maior afluência é Segunda-feira com 17% dos episódios; 75% dos epsiódios ocorre entre as 8h - 20h, periodo de funcionamento dos Centros de Saúde. Foram considerados como não urgentes, 54,9% dos episódios, 88,8% destes são encaminhados para o Centro de Saúde. São não referenciados 90% dos episódios. Existe evidência de utilização injustificada do Serviço de Urgência Pediátrica por 49,5% dos utentes. Verifica-se que a utilização do serviço de urgência depende da residência dos utentes (p=0,001), a população da Amadora recorre mais à urgência. Existe evidência de relação entre o dia da semana e o acesso injustificado (p <0,001), quinta-feira apresenta 17,3% dos episódios não justificados. A recorrência injustificada ao serviço de urgência não depende do género (p=0,137). Existe relação entre a idade e a recorrência justificada, sendo estatisticamente significativa (p=0,006). Conclusão: Pode concluir-se que a “sobre utilização” e “inadequação” da procura são fenómenos presentes no Serviço de Urgência Pediátrica. Assim urgem medidas de contenção da utilização indevida, passando estas provavelmente por uma consciencialização e educação da população. - ABSTRACT - Introduction: Currently the overuse of Pediatric Emergency hospital services is a major concern of managers and hospital administrators. This misure may contribute to increased costs because of the inordinate demand is not appropriate for this type of service. The demand for rapid response to health problems contributing to the influx exaggerated and sometimes unjustified by the population. Objective: The aim of this study was carried out to characterize the use of emergency pediatric hospital in the metropolitan area of Lisbon, in order to understand whether there is or not unjustified demand for health care. Methods: We used it as a methodological support a quantitative approach, a descriptive study - correlation. We analyzed 36,932 episodes of pediatric emergency occurring in a period of six months (July 2010 to January 2011). Results: The sample consists of 53.6% of male users and 46.4% female, where the most representative age range is between 1 and 5 years old. The Municipality of Sintra has 61% of the episodes, but the proportion of the county Amadora Pediatric Emergency appeals more to the 7.48% of the episodes. Monday 17% of the episodes is the busiest day, 75% of episodes occurs between 8 am - 20 h period of operation of the Health Centres were considered non-urgent, 54.9% of episodes, 88.8 % of these are referred to the Health Center They are not referenced 90% of episodes. There is evidence of unjustified use of the Pediatric ER for 49.5% of users. It appears that the use of emergency service depends on the residence of users (p = 0.001), the population of Amadora uses more urgency. There is evidence of a relationship between the day of the week and unjustified access (p <0.001), Thursday shows 17.3% of the episodes are not justified. Recurrence unjustified the emergency room does not depend on gender (p = 0.137). There is a relationship between age and recurrence justified statistically significant (p = 0.006). Conclusion: It can be concluded that "on use" and "inadequacy" of demand phenomena are present in the Pediatric ER. So urge measures to curb misuse, these probably passing an awareness and education of the population.
