Strategies of Active Dissemination of Workplace Health Promotion

Purpose – A growing body of literature provides evidence for the efficacy of workplace health promotion (WHP). However, little is known about effective dissemination strategies for WHP interventions. The purpose of this paper is to describe how a WHP agency in Zurich, Switzerland, used bulk mailings, information events, telephone marketing and free initial consultations for the large-scale geographic marketing of WHP services, with a focus on tobacco prevention (TP). Design/methodology/approach – To analyze the number of companies responding positively to solicitation, examine the predictors of positive responses and explore the reasons for negative responses, the authors used both quantitative (e.g. a standardized questionnaire) and qualitative (telephone interviews) methods. Findings – The results show that except for telephone marketing (69 percent), the success rates of dissemination activities were very low (3-9 percent). Predictors for a positive response were institutionalization of WHP, the representative’s personal concern about TP, and problems with environmental tobacco smoke within the company. The most prominent reason for a negative Response was that the companies had already implemented TP measures by themselves and needed no further external support. Practical implications – It is suggested that TP was the wrong emphasis for a WHP program to be disseminated at that particular time, because a law on protection from passive smoking was introduced in Switzerland shortly afterwards. Originality/value – The study examines dissemination strategies under real-life Consulting conditions. It builds on on a large sample of companies and uses both quantitative and qualitative research methods. It reports specific numbers and success rates of marketing activities and thereby contributes to the knowledge about an important issue for intervention planning in the field of WHP.

A VERDADE É A CONVERSA: Aproximações inesperadas entre o neo-pragmatismo de Richard Rorty e a Teologia da Libertação em Juan Luis Segundo

Este estudo é uma tentativa de promover uma partilha de perspectivas entre o neo-pragmatismo do filósofo Richard Rorty, mormente a partir das obras Filosofia e o espelho da natureza e Contingência, Ironia e Solidariedade e a Teologia da Libertação, em seu mais proeminente representante, Juan Luis Segundo, com o foco principal nas obras Libertação da teologia e O dogma que liberta. Desenvolve-se aqui uma aproximação de olhares para a verdade e a revelação, concebendo-as como processos pedagógicos. A verdade, como conceito não apenas religioso, do que se busca para dar sentido ao mundo e a vida humana e a revelação, como uma experiência marcada pela linguagem e expectativas religiosas de significado existencial são experiências similares e constituem-se não como o resultado de um processo de aprendizagem, mas como o processo em si mesmo, aberto e em constante renovação. A verdade, assim, não seria aonde se chega, mas os caminhos pelos quais se vai. Encontrar os pontos de contato e as possíveis mútuas contribuições do pensamento do filósofo Richard Rorty, e sua filosofia edificante, e do teólogo Juan Luis Segundo, e sua ideia de revelação como processo pedagógico, será meu esforço de aproximação entre suas proposições e a construção de uma proposta que não fuja à linguagem e condição humanas. O humano, que marcado pela liberdade, tem na contingência de suas construções um limite para as suas conquistas e um espaço para a sua libertação de qualquer processo desumanizador.

Physical Design Methodologies for Low Power and Reliable 3D ICs

As the semiconductor industry struggles to maintain its momentum down the path following the Moore's Law, three dimensional integrated circuit (3D IC) technology has emerged as a promising solution to achieve higher integration density, better performance, and lower power consumption. However, despite its significant improvement in electrical performance, 3D IC presents several serious physical design challenges. In this dissertation, we investigate physical design methodologies for 3D ICs with primary focus on two areas: low power 3D clock tree design, and reliability degradation modeling and management. Clock trees are essential parts for digital system which dissipate a large amount of power due to high capacitive loads. The majority of existing 3D clock tree designs focus on minimizing the total wire length, which produces sub-optimal results for power optimization. In this dissertation, we formulate a 3D clock tree design flow which directly optimizes for clock power. Besides, we also investigate the design methodology for clock gating a 3D clock tree, which uses shutdown gates to selectively turn off unnecessary clock activities. Different from the common assumption in 2D ICs that shutdown gates are cheap thus can be applied at every clock node, shutdown gates in 3D ICs introduce additional control TSVs, which compete with clock TSVs for placement resources. We explore the design methodologies to produce the optimal allocation and placement for clock and control TSVs so that the clock power is minimized. We show that the proposed synthesis flow saves significant clock power while accounting for available TSV placement area. Vertical integration also brings new reliability challenges including TSV's electromigration (EM) and several other reliability loss mechanisms caused by TSV-induced stress. These reliability loss models involve complex inter-dependencies between electrical and thermal conditions, which have not been investigated in the past. In this dissertation we set up an electrical/thermal/reliability co-simulation framework to capture the transient of reliability loss in 3D ICs. We further derive and validate an analytical reliability objective function that can be integrated into the 3D placement design flow. The reliability aware placement scheme enables co-design and co-optimization of both the electrical and reliability property, thus improves both the circuit's performance and its lifetime. Our electrical/reliability co-design scheme avoids unnecessary design cycles or application of ad-hoc fixes that lead to sub-optimal performance. Vertical integration also enables stacking DRAM on top of CPU, providing high bandwidth and short latency. However, non-uniform voltage fluctuation and local thermal hotspot in CPU layers are coupled into DRAM layers, causing a non-uniform bit-cell leakage (thereby bit flip) distribution. We propose a performance-power-resilience simulation framework to capture DRAM soft error in 3D multi-core CPU systems. In addition, a dynamic resilience management (DRM) scheme is investigated, which adaptively tunes CPU's operating points to adjust DRAM's voltage noise and thermal condition during runtime. The DRM uses dynamic frequency scaling to achieve a resilience borrow-in strategy, which effectively enhances DRAM's resilience without sacrificing performance. The proposed physical design methodologies should act as important building blocks for 3D ICs and push 3D ICs toward mainstream acceptance in the near future.

Cardiovascular disease and the changing face of global public health : a focus on low and middle income countries

Eighty percent of the global 17 million deaths due to cardiovascular disease (CVD) occur in low and middle income countries (LMICs). The burden of CVD and other noncommunicable diseases (NCDs) is expected to markedly increase because of the global aging of the population and increasing exposure to detrimental lifestyle-related risk in LMICs. Interventions to reduce four main risks related to modifiable behaviors (tobacco use, unhealthy diet, low physical activity and excess alcohol consumption) are key elements for effective primary prevention of the four main NCDs (CVD, cancer, diabetes and chronic pulmonary disease). These behaviors are best improved through structural interventions (e.g., clean air policy, taxes on cigarettes, new recipes for processed foods with reduced salt and fat, urban shaping to improve mobility, etc.). In addition, health systems in LMICs should be reoriented to deliver integrated cost-effective treatment to persons at high risk at the primary health care level. The full implementation of a small number of highly cost effective, affordable and scalable interventions ("best buys") is likely to be the necessary and sufficient ingredient for curbing NCDs in LMICs. NCDs are both a cause and a consequence of poverty. It is therefore important to frame NCD prevention and control within the broader context of social determinants and development agenda. The recent emphasis on NCDs at a number of health and economic forums (including the September 2011 High Level Meeting on NCDs at the United Nations) provides a new opportunity to move the NCD agenda forward in LMICs.

Effect of Nd:YAG laser combined with fluoride on the prevention of primary tooth enamel demineralization

Most studies dealing with the caries preventive action of Nd:YAG laser have been done in permanent teeth and studies on primary teeth are still lacking. The aim of this study was to evaluate in vitro the effect of Nd:YAG laser combined or not with fluoride sources on the acid resistance of primary tooth enamel after artificial caries induction by assessing longitudinal microhardness and demineralization depth. Sixty enamel blocks obtained from the buccal/lingual surface of exfoliated human primary molars were coated with nail polish/wax, leaving only a 9 mm² area exposed on the outer enamel surface, and randomly assigned to 6 groups (n=10) according to the type of treatment: C-control (no treatment); APF: 1.23% acidulated phosphate fluoride gel; FV: 5% fluoride varnish; L: Nd:YAG laser 0.5 W/10 Hz in contact mode; APFL: fluoride gel + laser; FVL: fluoride varnish + laser. After treatment, the specimens were subjected to a des-remineralization cycle for induction of artificial caries lesions. Longitudinal microhardness data (%LMC) were analyzed by the Kruskal-Wallis test and demineralization depth data were analyzed by oneway ANOVA and Fisher’s LSD test (á=0.05). APFL and APF groups presented the lowest percentage of microhardness change (p<0.05). Demineralization depth was smaller in all treated groups compared with the untreated control. In conclusion, Nd:YAG laser combined or not with fluoride gel/varnish was not more effective than fluoride alone to prevent enamel demineralization within the experimental period.

National suicide prevention strategy for Afghanistan (NSPS)

RESUMO: Do suicídio no Afeganistão é uma prioridade de saúde pública. O Afeganistão é um país de baixo rendimento, emergindo de três décadas de conflitos. Há uma alta prevalência de sofrimento psicológico, perturbações mentais e abuso de substâncias. Existem várias questões sociais, tais como, desequilíbrio/violência de género, pobreza, atitudes e costumes obsoletos, rápidas mudanças sócio-culturais, violação dos direitos humanos e especialmente dos direitos das mulheres e das crianças. Estes fatores de risco contribuem para o aumento da vulnerabilidade da população em relação ao suicídio. A relativa alta taxa de suicídio no Afeganistão é especialmente significativa comparada com as taxas baixas em todos os países islâmicos. Os estudos mostraram predominância de suicídio nas mulheres (95%) e em pessoas jovens. Existe, por isso, uma necessidade urgente do país ter uma estratégia de prevenção do suicídio. A estratégia foi desenvolvida pela criação de um grupo técnico/ de assessoria multi-sectorial de diferentes intervenientes tais como governo, ONGs, agências doadoras, as famílias das vítimas e outraas partes interessadas. A estratégia baseia-se os seguintes valores chave:, respeito pelas diversidades; sensibilidade para as questões sócio-cultura-religiosa e de género; promoção da dignidade da sociedade; respeito pelos direitos humanoss.. Os 'seis pontos estratégicos' são: envolvimento das principais partes interessadas e criação de colaboração intersectorial coordenada; fornecimento de cuidados às pessoas que fazem tentativas de suicídio e às suas famílias; melhoria dos serviços para pessoas com doença mental e problemas psicossociais; promover uma comunicação e imagem adequada dos comportamentos suicidas, pelos meios de comunicação; reduzir o acesso aos meios de suicídio e coligir informação sobre as taxas de suicídio, os fatores de risco, os fatores protetores e as intervenções eficazes. A estratégia nacional de prevenção do suicídio será inicialmente implementada por 5 anos, com uma avaliação anual do plano de acção para entender os seus pontos fortes e limitações. Recomendações e sugestões serão incorporadas nos próxima planos anuais para uma intervenção eficaz. Um sistema de monitorização irá medir o progresso na implementação da estratégia.-----------------------------ABSTRACT: Suicide in Afghanistan is a public health priority. Afghanistan is a low-income country, emerging from three decades of conflicts. There is high prevalence of mental distress, mental disorders and substance abuse. There are multiple social issues, such as gender imbalance/violence, poverty, obsolete attitudes and customs, rapid social-cultural changes, human right violations, and especially women and children rights. These risk factors contribute to increase the vulnerability of the population for suicide. The relative high rate of suicide in Afghanistan is especially significant as the rates are low in all Islamic countries. Research studies have shown predominance of suicide in women (95%) and in young age people. There is an urgent need for the country to have a suicide prevention strategy. The strategy has been developed by establishing a multi-sectoral technical/advisory group of different stakeholders from government, NGOs, donor agencies, victim’s families, and interested parties. The strategy is based on the following key values, namely, respect for diversities; sensitiveness to socio-culture-religious and gender issues; promotion of the society dignity and respect for the human rights of people. The six ‘Strategic directions’ are: involving key stakeholders and creating coordinated inter-sectoral collaboration; providing after care for people making a suicide attempt and their families; improving services for people with mental disorders and psycho-social problems; promoting the safe reporting and image of suicidal behaviour by media; reducing access to the means of suicide and gathering information about suicide rates, risk factor, protective factors and effective interventions. The National Suicide Prevention Strategy will be initially implemented for 5 years, with an annual evaluation of the action plan to understand the strengths and limitations. Recommendations and suggestions will be incorporated into the next annual plans for effective intervention. A monitoring framework will measure progress in implementing the strategy.

Temporal variability and trends of the downward solar radiation over Europe during the 20th century, with regional focus in the dimming/brightening phenomena on the Iberian Peninsula

Proyecto de investigación elaborado a partir de una estancia en el Institute for Atmospheric and Climate Science, a Alemanya, entre 2010 y 2012. La radiación solar que alcanza la superficie terrestre es un factor clave entre los procesos que controlan el clima de la Tierra, dado el papel que desempeñan en el balance energético y el ciclo hidrológico. Establecer su contribución al cambio climático reciente supone una gran dificultad debido a la complejidad de los procesos implicados, la gran cantidad de información requerida, y la incertidumbre de las bases de datos disponibles en la actualidad. Así, el objetivo principal del proyecto ha consistido en generar una base de datos de insolación incluyendo las series más largas (desde finales del siglo XIX) disponibles en toda Europa. Esta base de datos complementa para nuestro continente el Global Energy Balance Archive (GEBA) que mantiene y gestiona el grupo que ha acogido al receptor de la ayuda postdoctoral, y permite extender espacial (especialmente en países del sur de Europa) y temporalmente las series climáticas disponibles de mediciones de irradiancia solar. Como la insolación es un proxy de la irradiancia solar, el proyecto actual también ha tratado de calibrar de forma exhaustiva ambas variables, a fin de generar una nueva base de datos reconstruida de esta segunda variable que esté disponible desde finales del siglo XIX en Europa. Un segundo objetivo del proyecto ha consistido en continuar trabajando a escala de mayor detalle sobre la Península Ibérica, con el fin de proporcionar una mejor comprensión del fenómeno del “global dimming/brightening” y su impacto en el ciclo hidrológico y balance energético. Finalmente, un tercer objetivo del presente proyecto postdoctoral ha consistido en continuar estudiando los posibles ciclos semanales a gran escala de diferentes variables climáticas, línea de investigación de interés para la detección de posibles efectos de los aerosoles antrópicos en el clima a escalas temporales breves, y consecuentemente estrechamente vinculado al fenómeno del “global dimming/brightening”.

Burnout syndrome and Brazilian civil aviation: a short essay on the focus on prevention

Introduction: At the same time that there are increased demands we have become more sedentary, increasing risk factors for new diseases. All this reflects on our quality of life with special emphasis upon a particular syndrome called Burnout. Aviation is no exception and packed into its processes each day more expeditious, promotes a perfect environment for the development and spread of the syndrome. Aim: To evaluate the quality of life, organizational climate, and the level of physical activity among employees of a Brazilian airline. Methods: A cross-sectional design was conducted with 8 subjects. Results: Total score on the WHOQOL quality of life questionnaire was 64.7 (SD 10.8), and the environmental field showed the lowest score. Nevertheless, the sedentary risk factor was performed in 25% of the sample. About the organizational climate, it can be seen that 6.12% of the sample was framed in "Professional Exhaustive", 29.60% in the condition of "Warning", and 64.37% in the condition of "Professional Efficiency". Conclusion: the study found a low quality of life, especially in the environmental category, sedentary people and a large proportion of employees in this Brazilian airline with negative scores on the Organizational Climate.

Influence of gender on the clinical and laboratory spectra of patients with primary antiphospholipid syndrome

The objectives of this cross-sectional study were to evaluate the differences between males and females in the clinical and biochemical manifestations of primary antiphospholipid antibody syndrome (PAPS). The method involved 49 patients (38 premenopausal females and 11 males) diagnosed with PAPS (according to the Sapporo criteria) and their demographic data, clinical data, medications used and antiphospholipid antibodies were analyzed. The results of this study are as follows. Both the groups of patients were statistically similar regarding age, race, weight and body mass index. However, males were significantly taller than females (172 +/- A 8.9 vs. 159.2 +/- A 6.2 cm, p < 0.0001). The duration of disease was similar for females and males. The prevalence of pulmonary thromboembolism was higher in females than in males (34.2 vs. 0.0%, p = 0.024). Regarding other PAPS manifestations (arterial events, venous events, deep venous thrombosis, thrombocytopenia, acute myocardial infarction, angina, cerebrovascular accidents and Sneddon syndrome), comorbidities (arterial hypertension and dyslipidemia), lifestyle (physical activity, previous smoking and current smoking) and the use of medications (current and previous use of corticosteroids, as well as the use of statins or chloroquine), both groups were statistically similar (p > 0.05). More females than males tested positive for IgM anticardiolipin antibodies (76.3 vs. 36.4%, p = 0.025) or for at least one of the antiphospholipid antibodies tested (either IgM anticardiolipin or IgG anticardiolipin 84.2 vs. 45.5%, p = 0.016). However, both groups were similar regarding the frequency of positivity for lupus anticoagulant and isolated IgG anticardiolipin, as well as regarding mean levels of IgG and IgM anticardiolipin (p > 0.05). We concluded that, among PAPS patients, the frequency of pulmonary thromboembolism and of positivity for IgM anticardiolipin is higher in females than in males. Our findings show that there are gender differences in PAPS, differences that might be related to alterations in sex hormones.
