Mortalidade por doenças infecciosas e parasitárias em Salvador - Bahia: evolução e diferenciais intra-urbanos segundo condições de vida

Analisa-se a evolução da mortalidade por DIP em Salvador-BA e seus diferenciais intra-urbanos mediante estudo de série temporal e de agregados espaciais, nos anos noventa. O DATASUS e declarações de óbitos foram as fontes de dados. Na análise temporal, empregou-se mortalidade proporcional, taxa de mortalidade e razão de mortalidade padronizada (RMP). No estudo espacial, analisou-se as taxas de mortalidade por DIP segundo um índice de condições de vida (ICV). Entre 1991 e 1995, a mortalidade proporcional por DIP foi de 8,3% e o risco de morrer variou entre 55,9 e 34,0 por 100 mil habitantes. No período seguinte, a variação foi entre 52,8 e 41,1 por 100 mil habitantes. A razão de mortalidade padronizada por doenças infecciosas e parasitárias em 1998 foi de 1,3. As doenças infecciosas intestinais continuam sendo uma das principais causas de morte desse grupo. As áreas da cidade onde as condições de vida eram mais baixas concentravam as maiores taxas de mortalidade por DIP. A despeito do declínio, ainda existe um excesso de mortalidade por DIP em Salvador. O modelo de desenvolvimento do país e a reemergência de algumas doenças podem estar contribuindo para este padrão.

Differences in ERP use and value across Iberian Manufacturing and Services SMEs

Enterprise Resource Planning (ERP) system literature reports very little research on post-adoption stages, that is, actual usage and value. Even fewer studies focus on the specificities of an industry analysis. Based on the Technology-Organizational-Environment (TOE) framework and the Resource-Based View (RBV) theory, we develop a research model to measure and examine determinants of ERP use and value and their impact in the Iberian region (Portugal and Spain) across Manufacturing and Services industries in Small and Medium Enterprises (SMEs). The empirical test was conducted through structural equation modelling, using data from 261 firms in the peninsula in the Manufacturing and Service industries. Results show that amongst ERP use determinants, Training is the most important determinant for Service firms and Compatibility for Manufacturing firms. Firm size, Analytics, and Collaboration contribute to ERP Value in both industries, with Analytics being more important for the Service industry. The paper provides insight into which determinants contribute to ERP use and ERP value in Iberian Manufacturing and Services SMEs, offering managerial and academic implications.

Modificações na prevalência das lesões intra-epiteliais escamosas cervicais e dos fatores de risco em pacientes HIV/AIDS atendidas em serviço especializado no sul do Brasil nos períodos 1995-1999 e 2006-2007

O objetivo deste trabalho foi estudar mudanças na prevalência de lesões intra-epiteliais escamosas cervicais entre mulheres HIV-1 positivas após a introdução da terapia antiretroviral altamente eficaz e avaliar modificações na prevalência de fatores de risco para lesões intra-epiteliais escamosas cervicais. Foram estudadas 50 pacientes em 1995-1999 e 120 pacientes em 2006-2007. Coletaram-se dados demográficos, comportamentais, laboratoriais. Calculou-se a prevalência de lesões intra-epiteliais escamosas cervicais entre os dois períodos, assim como as prevalências dos outros fatores de risco. No primeiro período, encontrou-se uma prevalência de lesões intra-epiteliais escamosas cervicais de 66% e no segundo de 43% (p=0,007). A média do CD4 em 1995-1999 foi de 275,71 (DP 283,23); a média do CD4 em 2006-2007 foi de 463,32 (DP 231.90), (p=0,001). Houve mudanças significativas nos fatores idade, cor, estado conjugal e fumo entre os dois períodos. A diminuição da prevalência de lesões intra-epiteliais escamosas cervicais pode estar relacionada ao uso da estratégia de terapia antiretroviral altamente eficaz assim como à mudança de fatores de risco para lesões intra-epiteliais escamosas cervicais ao longo do tempo.

Trust, alliance management capability and the alliance management function: A comparative analysis of Portuguese SMEs

Strategic alliances represent a key driver for internationalization and growth, being the purpose of this work project to better understand the intertwined relationship between trust and the existence of an alliance management position. Previous research supports the positive impact of such position in stock market returns. However, little attention has been given to the impact of such position on the level of trust in the collaborative arrangement, which is deemed to be a key driver for alliance success. A qualitative comparative case-study of three Portuguese SMEs is used to draw conclusions from the literature to real life business cases and it demonstrates the positive impact of an alliance management position on trust.

Enterprise risk management adoption: An empirical investigation of its effects on firm performance

Enterprise Risk Management (ERM) is gaining relevance among financial and non-financial companies but its benefits still are uncertain. This paper aims at investigating the relationship between ERM adoption and firm performance based on a sample of 1130 non-financial companies belonging to the STOXX® index. A content analysis of individual accounts is performed to distinguish adopters, and a regression analysis explores the effect of ERM adoption on firm performance, proxied by Tobin’s Q. The findings suggest that there is a statistical significant positive effect of ERM adoption on firm performance, meaning that firms are benefiting from the implementation of this process.

The firm delocalization decision

In the current paper, the determinants of firm international relocation decision in twenty-six European countries during the period 2004-2014 are analyzed. We demonstrate, at light of three different but complementary theories that neoclassical, behavioural and institutional „push‟ factors have an impact in a firm decision-making process. Findings support that firm size, access to a global network, foreign capital, and negative internal growth in the workforce induce firm relocation. On the other hand, the degree of sunk assets has a negative effect on the probability of relocation. Delocalization decisions are also sector-dependent with low-tech manufacturing firms paying high salaries relocating abroad with a greater likelihood.

The effectiveness of supply chain management on firm's performance: A comparative case study

The purpose of the paper is to investigate the effectiveness of supply chain management (SCM) practices to increase a company’s performance based on a cross-border and cross-sector analysis. The paper follows a comparative case study approach which was achieved by interviewing supply chain management experts of three companies operating in different industries and positions in a supply chain. Practices that were mutually applied by the firms and their contribution to achieve quality, economic, cost, and time advantages were analyzed. The paper revealed practices, which contribute the most to increase specific performance areas.

Implementação da Equipa de Emergência Médica Intra-hospitalar nos hospitais do Serviço Nacional de Saúde : análise de custo-efetividade perante a incidência da paragem cárdio-respiratória intra-hospitalar

RESUMO - Introdução: No âmbito das emergências intra-hospitalares investigou-se a hipótese da presença da Equipa Emergência Médica Intra-hospitalar (EEMI) (DGS, 2010) num Centro Hospitalar (CH), contribuir para a redução do número de mortos por Paragem Cárdiorespiratória (PCR) intra-hospitalar, quando comparado com outro CH dotado de uma equipa tradicional de resposta à PCR. Metodologia: Tratou-se de um estudo observacional, retrospetivo (2010 a 2014), com base nos dados do Grupo de Diagnóstico Homogéneo (GDH), analisado numa perspetiva de custo-efetividade no impacto sobre incidência de PCR e taxa de mortalidade. Resultados: Observou-se que o CH com EEMI apresentou uma Redução Risco Absoluto (RRA) de 9,01% de morte por PCR. A taxa de mortalidade calculada foi de 2,82 casos por 1000 episódios de internamento em que a incidência de PCR foi de 28,24 casos por cada 10 000 habitantes, duas vezes menor que CH em comparação. Quando introduzidas manobras de Ressuscitação Cárdiopulmonar (RCP), o mesmo CH teve um maior número de PCR revertidas, com uma taxa de mortalidade 2 vezes menor que o CH sem EEMI. Conclusão: Resultados demonstraram que os dois CH apresentaram riscos diferentes, em que a probabilidade do doente hospitalizado de morrer após ocorrência de PCR foi menor no grupo exposto à EEMI, com OR = 0,496 [IC 95% (0,372 a 0,662)] para dados populacionais (p = 0,0013), e OR = 0,618 [IC 95% (0,298 a 1,281)] para dados individuais, (p = 0,194). Face a melhores resultados em Saúde, considerou-se a implementação da EEMI, uma medida custo-efetiva, uma vez que o principal requisito traduz-se por reorganização das equipas tradicionais para uma vertente de prevenção da PCR.

Prenatal tracheal ligation or intra-amniotic administration of surfactant or dexamethasone prevents some structural changes in the pulmonary arteries of surgically created diaphragmatic hernia in rabbits

PURPOSE: Characterization of the structural changes occurring in the pulmonary arteries resulting from surgically produced congenital diaphragmatic hernia in rabbits, with particular emphasis on the preventive effects of prenatal tracheal ligation or administration of intra-amniotic dexamethasone or surfactant. METHODS: Twenty rabbit fetuses underwent surgical creation of a left-sided congenital diaphragmatic hernia on the 24th or 25th gestational day. They were divided according to the following procedures: congenital diaphragmatic hernia (n = 5), congenital diaphragmatic hernia plus tracheal ligation (n = 5), congenital diaphragmatic hernia plus intra-amniotic administration of dexamethasone 0.4 mg (n = 5) or surfactant (Curosurf 40 mg, n = 5). On gestational day 30, all the fetuses were delivered by caesarean section and killed. A control group consisted of five nonoperated fetuses. Histomorphometric analysis of medial thickness, cell nuclei density, and elastic fiber density of pulmonary arterial walls was performed. RESULTS: Arteries with an external diameter > 100 mum have a decreased medial thickness, lower cell nuclei density, and greater elastic fiber density when compared with arteries with external diameter <= 100 mum. Congenital diaphragmatic hernia promoted a significant decrease in medial thickness and an increase in cell nuclei density in artery walls with external diameter > 100 mum. Prenatal treatments with tracheal ligation or intra-amniotic administration of dexamethasone or surfactant prevented these changes. In arteries with external diameter <= 100 mum, congenital diaphragmatic hernia promoted a significant increase in medial thickness and in cell nuclei density and a decrease in elastic fiber density. The prenatal treatments with tracheal ligation or intra-amniotic administration of dexamethasone or surfactant prevented these changes, although no effect was observed in elastic fiber density in the congenital diaphragmatic hernia plus dexamethasone group. CONCLUSIONS: Congenital diaphragmatic hernia promoted different structural changes for large or small arteries. The prenatal intra-amniotic administration of dexamethasone or surfactant had positive effects on the lung structural changes promoted by congenital diaphragmatic hernia, and these effects were comparable to the changes induced by tracheal ligation.

Bias in returns to tenure when firm wages and employment comove: A quantitative assessment and solution

It is well known that, unless worker-firm match quality is controlled for, returns to firm tenure (RTT) estimated directly via reduced form wage (Mincer) equations will be biased. In this paper we show that even if match quality is properly controlled for there is a further pervasive source of bias, namely the co-movement of firm employment and firm wages. In a simple mechanical model where human capital is absent and separation is exogenous we show that positively covarying shocks (either aggregate or firm level) to firms employment and wages cause downward bias in OLS regression estimates of RTT. We show that the long established procedures for dealing with "traditional" RTT bias do not circumvent the additional problem we have identified. We argue that if a reduced form estimation of RTT is undertaken, firm-year fixed effects must be added in order to eliminate this bias. Estimates from two large panel datasets from Portugal and Germany show that the bias is empirically important. Adding firm-year fixed effects to the regression increases estimates of RTT in the two respective countries by between 3.5% and 4.5% of wages at 20 years of tenure over 80% (50%) of the estimated RTT level itself. The results extend to tenure correlates used in macroeconomics such as the minimum unemployment rate since joining the firm. Adding firm-year fixed effects changes estimates of these effects also.

Role of Intersectoral Collaboration in Mental Health Policy Formulation And Service Delivery in Saint Lucia

RESUMO: Santa Lúcia pequena ilha de país em desenvolvimento com recursos limitados e é confrontada com uma série de desafios socioeconômicos que exigem soluções criativas e inovadoras. É comprovado que a combinação de recursos entre setores para estabelecer os determinantes social, econômico e ambiental da saúde são uma estratégia útil para melhorar a saúde da população, principalmente a sua saúde mental. Este estudo, o primeiro do seu tipo em Santa Lúcia, procurou examinar até que ponto a disponibilidade de uma política nacional de saúde mental levou a ação intersetorial para o fornecimento de serviços e promoção da saúde mental. Além disso, o estudo examinou o nível de colaboração intersetorial que existe entre as agências que prestam cuidados diretos e serviços de suporte para pessoas com doenças mentais e problemas sérios de saúde mental. O estudo também teve como objetivo identificar os fatores que promovem ou dificultam a colaboração intersectorial e gerar recomendações que possam ser aplicadas para países muito pequenos e com perfis socioeconômicos semelhantes. Os dados gerados a partir de três (3) fontes foram sintetizados para formar uma visão ampla das questões. Uma avaliação da política de saúde mental de 2007, uma avaliação que identifica até que ponto a ação intersetorial atualmente deixa a prestação de serviços de saúde mental e a administração de entrevistas semiestruturadas nas mãos de gestores do programa de diferentes agências em todos os setores. O estudo concluiu que, apesar da disponibilidade de uma política de saúde mental, que articula clara e explicitamente a colaboração intersetorial como área prioritária para ação, quase não existe no sistema de fornecimento atual do serviço. Os provedores de serviços em todos os setores reconhecem que há os benefícios da colaboração intersectorial e com entraves significativos em relação à colaboração intersetorial, que por sua vez, impede uma abordagem nacional para o planejamento e o fornecimento do serviço. A colaboração intersetorial não será possível se os próprios setores dependerem da abordagem direta do setor da saúde ou se a atmosfera geral for ofuscada pela estigmatização das doenças mentais.------------------------------------------------------------------------ABSTRACT: Saint Lucia a small island developing country with limited resources, is faced with a number of socio-economic challenges which require creative and innovative solutions to address. Combining resources across sectors to address the social, economic and environmental determinants of health has proven to be a useful strategy for improving population health in particular mental health. This study, the first of its kind for Saint Lucia sought to examine the extent to which the availability of a national mental health policy led to intersectoral action for mental health promotion and service delivery. In addition the study examined the level of intersectoral collaboration which actually exist between agencies which provide direct care and support services to people with mental illnesses and significant mental health problems. The study also aimed to identify the factors which promote or hinder intersectoral collaboration and generate recommendations which can be applied to extremely small countries with similar socio-economic profiles. Data generated from three (3) sources was synthesized to form a broad picture of the issues. An evaluation of the mental health policy of 2007, an assessment of the extent to which intersectoral action currently exist in mental health service delivery and the administration of semi-structured interviews with program managers from different agencies across sectors to identify implementation issues. The study concluded that despite the availability of a mental health policy which clearly and explicitly articulates intersectoral collaboration as a priority area for action, very little exists in the current service delivery system. Services providers across sectors acknowledge the benefits of intersectoral collaboration and that there are significant barriers to intersectoral collaboration, which in turn hinders a national approach to service planning and delivery. Intersectoral collaboration is not possible if sectors themselves are dependent on a top-down health sector driven and dominated approach, or if the general atmosphere is clouded by stigmatization of mental health illnesses.

The relationship between the education level of successor's and the firm performance in German publicly listed family firms- an empirical analysis

The purpose of this thesis is to investigate how far the education level of the second or third generation of publicly traded German family firms affects the post-succession firm performance. By conducting a correlational and regression design, the aim is to examine how several variables influence the performance of family firms. Performance measures, for example ROA and Tobin’s q and variables, like Education level and succession periods, examine analytically that a positive succession trend will occur. However, with the used model, only a less rigid model shows empirical evidence.
