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.

Frequency of serum anti-cysticercus antibodies in the population of a rural Brazilian community (Cássia dos Coqueiros, SP) determined by ELISA and immunoblotting using Taenia crassiceps antigens

Considering the impact of cysticercosis on public health, especially the neurologic form of the disease, neurocysticercosis (NC), we studied the frequency of positivity of anti-Taenia solium cysticercus antibodies in serum samples from 1,863 inhabitants of Cássia dos Coqueiros, SP, a municipal district located 80 km from Ribeirão Preto, an area considered endemic for cysticercosis. The 1,863 samples were tested by enzyme linked immunosorbent assay (ELISA) using an antigenic extract from Taenia crassiceps vesicular fluid (Tcra). The reactive and inconclusive ELISA samples were tested by immunoblotting. Of the 459 samples submitted to immunoblotting, 40 were strongly immunoreactive to the immunodominant 18 and 14 kD peptides. Considering the use of immunoblotting as confirmatory due to its high specificity, the anti-cysticercus serum prevalence in this population was 2.1%.

Age-related seroprevalence study for St. Louis encephalitis in a population from Cordoba, Argentina

A serological screening was performed in 615 individuals aged 0-87 years, living in the city of Cordoba, Argentina to study the relationship between antibody prevalence for the SLE virus and age. A 13.98% prevalence of neutralizing antibodies was obtained and its relation to age was significantly high (p = 0.045). The highest seroprevalence was noted on individuals over 60 years old (>20%), whereas no subject under 10 was seropositive for this virus. Our results confirm that the agent is endemic in this area and neurological pathology studies should be performed on those individuals aged 60 since they represent the most susceptible group to SLE virus.

Contributo da manutenção técnica de edifícios para a sustentabilidade

A manutenção, durante vários anos, traduziu-se num conceito paliativo de instalações e equipamentos, o que se veio a revelar como uma atitude negligente perante o Homem e o Ambiente. As preocupações ambientais estão na ordem do dia e têm sido muitas as vozes que se têm levantado para que o consumo de energia seja mais equilibrado e para que as emissões de CO2 diminuam de forma a preservar o Planeta. De acordo com a resolução do Conselho Europeu, em 2007 (1), foi apresentado um pacote de propostas que visam a sustentabilidade e estimulam a Eficiência Energética (EE), com o objectivo de reduzir os consumos energéticos dos edifícios, quer estes sejam novos ou reabilitados. Segundo a Direcção Geral de Energia e Geologia os edifícios são responsáveis por 60% dos consumos de energia eléctrica, consumo esse que pode ser reduzido em mais de 50%, através de medidas de EE, traduzindo-se numa redução de 400 milhões de toneladas de CO2 por ano. (2) Para além de medidas de EE, também as práticas de manutenção preventiva podem contribuir para a diminuição dos consumos energéticos e de emissões de CO2. Segundo o Institute for Building Efficiency práticas de manutenção preventiva em equipamentos de Aquecimento Ventilação e Ar Condicionado (AVAC) reduzem os consumos energéticos de 10 a 20% e, em contrapartida, a negligência na execução da manutenção pode aumentar os consumos energéticos de 30 a 60%. (3) Uma outra análise de valores a ter em conta, é a Intensidade Energética (IE). Leia-se IE como sendo o valor global da energia consumida num país a dividir pelo seu produto interno bruto. A contribuição do sector dos serviços para a IE nacional era de 17% no ano de 2005. (4) Se a estes dados acrescentarmos que 70% dessa energia é consumida por equipamentos AVAC (5) e que práticas de manutenção reduzem esses valores entre 10 a 20%, pode concluir-se que a redução de custos energéticos associada à manutenção preventiva é efectiva e significativa. Apresentando um cenário ideal e hipotético, se ao contributo do sector dos serviços, para a IE nacional, se isolar o valor referente a equipamentos de AVAC, obtem-se uma IE de aproximadamente 12%. Se adicionalmente se considerar uma taxa de redução, relativa à execução da manutenção, entre 10 e 20%, Portugal obteria uma IE, relativamente aos consumos energéticos em edificios de serviços, não de 17% mas sim entre 14,6% e 15,8%. Neste trabalho pretende-se comprovar que um plano de actividades de manutenção equilibrado, monitorizado, e gerido de forma eficaz e funcional, é uma ferramenta fundamental no cumprimento de objectivos e metas europeias traçadas, que se reúnem num objectivo comum de preservação do planeta. A adopção deste tipo de medidas contribuirá para a racionalização dos consumos energéticos e para o aumento da vida útil dos equipamentos, bem como para a melhoria do desempenho económico e financeiro das organizações, tal como se poderá ler mais à frente neste trabalho. Será também analisado um caso prático, verificando a eficácia das medidas tomadas durante as intervenções preventivas de manutenção, sendo que para isso será estudado o comportamento de um equipamento, antes e após a realização de tarefas de manutenção preventiva. Tentar-se-á, junto de gestores de edifícios, recolher a opinião que têm sobre a importância da manutenção. Ao longo de toda a pesquisa foi possível consolidar a hipótese formulada inicialmente no que concerne ao contributo da manutenção para a sustentabilidade, quer através da revisão da literatura, quer nos testes efectuados a equipamentos. Foi possível confirmar que um plano de manutenção ajustado, monitorizado e cumprido é uma ferramenta na diminuição dos consumos energéticos, aumento da vida útil de equipamentos e por sua vez na diminuição de emissões de CO2. Verificou-se também que o controlo de poluentes e ventilação adequada dos edifícios são uma ferramenta essencial para a qualidade do ar interior, parâmetros facilmente controlados nas actividades de manutenção. O contributo das opiniões recolhidas entre os gestores de edifícios, para este estudo, foi também bastante importante, uma vez que todos eles reconhecem o papel importante da manutenção, mas nem todos estão sensibilizados para o seu papel na sustentabilidade do planeta. Nesta dissertação é deixado um alerta: o crescimento da população mundial e a consequente utilização de recursos naturais que são finitos, não sendo controlado de uma forma sustentada, pode resultar na destruição de um planeta único. O papel negativo do Homem nas alterações climáticas é inequívoco e é necessário melhorar a sua relação com o Ambiente. Cada ser humano está inserido na sua comunidade e dentro dela tem a sua função, cabe a cada um exercer esta responsabilidade nas suas actividades do dia-a-dia.

New prevalence estimate of TT virus (TTV) infection in low- and high-risk population from São Paulo, Brazil

The prevalence of TT virus (TTV) infection was investigated by Polymerase Chain Reaction (PCR) in low- (blood donors and healthy children/adolescents) and high-risk (hemophiliacs) groups from São Paulo, Brazil. Primers based on the untranslated region (UTR) of the viral genome proved to be much more ubiquitous, leading to much higher frequencies for both groups ( > or = 81%) than the earlier N22-PCR directed to the open reading frame 1 (blood donors, 5.5%, and hemophiliacs, 42.3%). The UTR-PCR also revealed an interesting profile for healthy children/adolescents: very high prevalence at the early years and significant decrease in male teenagers. The N22-PCR, in turn, demonstrated higher frequency in hemophiliacs treated with fresh blood products (58%), than in those treated with virus-inactivated clotting factors (9.4%) and blood donors (5.5%).

Comparison of different methods for work accidents investigation in hospitals: A Portuguese case study

BACKGROUND: The hospital environment has many occupational health risks that predispose healthcare workers to various kinds of work accidents. OBJECTIVE: This study aims to compare different methods for work accidents investigation and to verify their suitability in hospital environment. METHODS: For this purpose, we selected three types of accidents that were related with needle stick, worker fall and inadequate effort/movement during the mobilization of patients. A total of thirty accidents were analysed with six different work accidents investigation methods. RESULTS: The results showed that organizational factors were the group of causes which had the greatest impact in the three types of work accidents. CONCLUSIONS: The methods selected to be compared in this paper are applicable and appropriate for the work accidents investigation in hospitals. However, the Registration, Research and Analysis of Work Accidents method (RIAAT) showed to be an optimal technique to use in this context.

Seroprevalence of Helicobacter pylori infection in chronic chagasic patients, and in the rural and urban population from Uberlândia, Minas Gerais, Brazil

As patients with chronic Chagas disease exhibit morphological and functional changes of the stomach (hypomotility and hypochlorhydria), malnutrition, immunological deficiency and high prevalence of peptic disease associated to Helicobater pylori infection, the purpose of this study was to evaluate if the prevalence of H. pylori infection in chronic chagasic is higher than in non-chagasic individuals in the urban and rural population from Uberlândia, MG, Brazil. Serological determination of IgG antibodies to H. pylori was performed using a second-generation ELISA. Thus, 598 people were evaluated: 128 chagasic (CG), 222 non-chagasic living in urban area (U-NCG) and 248 non-chagasic living in rural area (R-NCG). Regarding the age range from 21 to 50 years, the prevalence of H. pylori infection in the CG (85.1%) was significantly higher than in the U-NCG (56.3%, p < 0.01) and the R-NCG (67.4%, p < 0.05). In the patients over 50 years, the prevalence in the CG (86.4%) was similar to the U-NCG (78.8%) and R-NCG (86.1%). Similar results were also found between the U-NCG and R-NCG for all age ranges, with prevalence rates of 29.1% and 35.3% for the age range from 5 to 13 years, and 47.2% and 40% for that from 14 to 20 years, respectively. We conclude that chagasic patients showed a higher seroprevalence of H. pylori infection than non-chagasic individuals, in the age range from 21 to 50 years, and that the prevalence of this infection was similar in the studied urban and rural non-chagasic population.

Prevalence of human herpesvirus 8 antibodies in the population of Belém, Pará, Brazil

Serum samples from 497 children and adults inhabiting two neighbourhoods (Guamá and Terra Firme) in Belém, Pará, North Brazil were screened for the presence of human herpesvirus 8 (HHV-8) antibody using an enzyme-linked immunosorbent assay. An overall 16.3% prevalence was found for these urban communities. Taken both genders together, prevalence rates of HHV-8 antibody increase gradually, across age-groups, ranging from 12.0% to 33.3%. When seroprevalence is analysed by gender, similar rates are found for female (18.4%) and male (14.0%) individuals. In the former gender group, seroprevalence rates increased from 10.3%, in children £ 10 years of age, to 30.0% in adults 41-50 years of age. Conversely, among male subjects, the prevalence of HHV-8 antibodies decreased from 13.3% in children/young adults aged £ 10 to 20 years of age to 6.1% in adults aged 21-30 years. From the 31-40 year-old group male onwards, seropositivity rates increased gradually, ranging from 8.3% to 66.7%. A significant difference in seropositivity rates was noted when comparing 21-30 age groups for female and male subjects: 23.3% and 6.1%, respectively (P = 0.03). Geometric mean optical densities were found to increase slightly from the lower to the higher age-groups. Our data suggest that transmission of HHV-8 occurs frequently in the general urban population of Belém, and that prevalence of antibody seems to increase with age.

Factores individuais que condicionam a Saúde : um estudo caso-controlo

RESUMO - O presente projecto enquadra-se no paradigma salutogénico e visa apurar alguns dos factores que determinam que algumas pessoas se apresentem mais saudáveis que a população em geral. Foi seleccionado um estudo, quantitativo, analítico tipo caso-controlo (1 caso para 3 controlos), em que os casos são constituídos por indivíduos integrando a Função Pública que se encontram acima do percentil 95 de assiduidade ao trabalho nos últimos dois anos e com uma auto-percepção de Saúde classificada como muito boa, os controlos são indivíduos que não obedecem à definição de caso. Os indivíduos serão emparelhados por idade, género, estado civil, carreira, categoria profissional e unidade funcional que integram. A assiduidade será calculada com recurso aos certificados de incapacidade temporária entregues nos respectivos serviços. Os factores a estudar são os mais citados na literatura como factores salutogénicos ou factores de protecção, são eles: - Sentido de Coerência de Antonowsky - Locus de controlo - Auto conceito -Auto Eficácia - Aptidão física nas três vertentes clássicas: Capacidade aeróbia, Composição corporal, Aptidão muscular. Todos estes factores serão estudados com recurso a questionários auto preenchidos devidamente testados e validados para o português de Portugal sendo a aptidão física apurada com recurso á bateria de testes "Fitness Gram" adoptada para Portugal pelo Instituto do Desporto de Portugal e pelo Ministério da Educação. Os resultados serão apurados com recurso ao software de análise epidemiológica EPIDAT. 3.1. ---------------- ABSTRACT - The present project follows the salutogénic paradigm and intends to identify some of the factors that determine why some people are healthier than the general population. It was selected a quantitative, analytic, case-control study type (1 case to 3 controls), in which the cases are constituted by individuals who are integrated in Public Services and find themselves above 95 percentile of assiduity in work in the last two years, and with a self-perception of Health classified as very good, the controls are individuals who don’t obey to the case definition. The individuals will be matched by age, gender, civil state, career, professional category and Functional Unity in the Health services. The assiduity will be calculated with the help of temporary incapacity certificates delivered in the respective services. The currently studying factors are the most cited in literature, like salutogenic factors or protection factors, are those: - Antonowsky’s Sense of Coherence - Locus Control - Self-concept - Self-Efficacy - The three classic strands of Physical Fitness: Aerobic Capacity, Corporal Composition, Muscular Fitness. All these factors will be studied with the resource of properly tested and validated self-filled questionnaires for Portugal Portuguese (language), with the Physical Fitness being determined with the resource of “Fitness Gram” test battery, adopted for Portugal by the Portuguese Sports Institute and the Education Ministry. The results will be determined with the resource of the epidemiologic analysis software EPIDAT. 3.1.

Characterization of the portuguese SSS into the Europe: a contribution

Nowadays, Short Sea Shipping (SSS) is an essential part in European multi-modal transport system, representing approximately thirty-seven per cent of intra-Community transactions in tonnes per kilometre (tkm). Since 2001, the European Shortsea Network (ESN) in partnership with the short-sea Promotion Centres (SPC) of each Member State of the European Union (EU) have managed to make significant progress in the promotion and development of this mode of transport. This paper aims to assess and analyse the SSS of containerised goods in Portugal and its articulation with other EU routes and also other transport modes. The current SSS infrastructure, how the sector is organized, as well as the future perspectives for the sector are also analysed for the case of Portugal. The analyses are based on a survey that was carried out on the logistics operators, navigation agents, freight forwarders, and the leading imports and exports manufacturers in Portugal.
