Company financial performance: Does board size matter? Case of the EUROSTOXX50 index

[EN] This study analyzes the relationship between board size and economic-financial performance in a sample of European firms that constitute the EUROSTOXX50 Index. Based on previous literature, resource dependency and agency theories, and considering regulation developed by the OECD and European Union on the normative of corporate governance for each country in the sample, the authors propose the hypotheses of both positive linear and quadratic relationships between the researched parameters. Using ROA as a benchmark of financial performance and the number of members of the board as measurement of the board size, two OLS estimations are performed. To confirm the robustness of the results the empirical study is tested with two other similar financial ratios, ROE and Tobin s Q. Due to the absence of significant results, an additional factor, firm size, is employed in order to check if it affects firm performance. Delving further into the nature of this relationship, it is revealed that there exists a strong and negative relation between firm size and financial performance. Consequently, it can be asseverated that the generic recommendation one size fits all cannot be applied in this case; which conforms to the Recommendations of the European Union that dissuade using generic models for all countries.

Os caminhos da avaliação de desempenho do setor saúde no Brasil: os dois lados do mesmo sistema de saúde

Esta revisão de literatura é fruto de indagações sobre a mudança na postura do Estado brasileiro no que concerne à avaliação na atualidade. A temática desta pesquisa é a inserção da ferramenta da avaliação de desempenho da saúde no Brasil. Mais precisamente, o estudo traz uma análise dos índices de desempenho do subsistema público (IDSUS) e do índice elaborado pela Agência Nacional de Saúde (ANS) para avaliar o subsistema privado da saúde (IDSS). Dessa maneira, esta dissertação tem como objetivo analisar os programas de qualificação do sistema de saúde brasileiro através da avaliação do Índice de Desempenho da Saúde Suplementar (IDSS) e do Índice de Desempenho do SUS (IDSUS), considerando seus impactos na relação público-privado do setor saúde. Para dar conta desses objetivos, a pesquisa examinou os Programas de Qualificação do Sistema de Saúde Brasileiro tanto na sua face pública quanto na privada, utilizando as técnicas de análise documental e bibliográfica. A análise transcorreu a partir do levantamento de documentos oficiais e da literatura produzida sobre o tema. Além da leitura de documentos da Agência Nacional de Saúde (ANS), Ministério da Saúde (MS), Instituto de Estudos da Saúde Suplementar (IESS), Federação de Seguros (FENASEG), Associação Brasileira de Medicina de Grupos (ABRAMGE) e Instituto Brasileiro de Geografia e Estatística (IBGE), foram consultados trabalhos acadêmicos e selecionados textos jornalísticos que evidenciaram o processo de implantação e utilização do Programa de Qualificação da Saúde no Brasil. A dissertação então trouxe à tona, admitindo como base a análise do IDSUS recentemente criado e do IDSS, a necessidade de se rediscutir as finalidades das avaliações de desempenho propostas. Tanto o IDSS quanto o IDSUS são iniciativas pioneiras positivas que podem e devem ser aprimoradas, para que possam de fato instrumentalizar o controle social e o gestor na priorização e no planejamento das ações de saúde. O instrumento utilizado pela ANS foi considerado eficaz, democrático e participativo no que diz respeito ao alcance dos objetivos do Programa de Qualificação das Operadoras de Planos de Saúde. O mesmo conseguiu integrar pressupostos de modelos e instrumentos de gestão referenciados pela literatura como modernos e eficazes, como a gestão por resultados. Promoveu não só mais transparência ao subsistema privado, mas induziu, em certa medida, a concorrência do setor. Já em relação à face pública, percebeu-se que mesmo em face da jovialidade da proposta do IDSUS, o mesmo mapeou alguns pontos críticos do subsistema e apontou a necessidade de se trabalhar o setor de forma mais eficiente. Entretanto, esta pesquisa concluiu que ambos os movimentos de avaliação dos subsistemas público e privado não se completam, não dialogam como deveriam, evidenciando uma dificuldade em perceber e organizar o sistema como um todo.

Avaliação da metodologia IQAFAL nas bacias contribuintes da Lagoa Rodrigo de Freitas, RJ, Brasil.

A pressão antrópica crescente impõe a necessidade de um monitoramento sistemático da água e de seus ambientes aquáticos. O desenvolvimento de Índices de Qualidade de Água (IQAs) tem como objetivo transformar dados em informações acessíveis e de fácil entendimento para os gestores e usuários das águas, visando refletir a deterioração deste recurso em nível de bacia hidrográfica e ao longo do tempo. O Instituto Estadual do Ambiente (INEA) adotou um novo Índice de Qualidade de Água para ambiente lótico, baseado em lógica nebulosa, o IQAFAL, desenvolvido no âmbito do rio Paraíba do Sul. O objetivo principal deste estudo consiste em aplicar o IQAFAL aos rios dos Macacos, Cabeça e Rainha, contribuintes da bacia de drenagem da Lagoa Rodrigo de Freitas, de grande interesse sócio-político-ambiental para a cidade do Rio de Janeiro. Busca-se analisar a sua adequação em sintetizar a qualidade de água em bacias hidrográficas de pequeno porte e primordialmente urbana. Para tanto, utilizam-se dados físicos, químicos e biológicos do INEA, no período 2003 - 2010. Os resultados mostraram que o IQAFAL foi capaz de refletir a qualidade da água de modo satisfatório e compatível com os registros disponíveis e a percepção de especialistas acerca da real qualidade dos rios. Ou seja, este Índice se mostrou mais sensível às condições ruins, traduzindo a verdadeira condição destes corpos dágua, ao contrário do IQACETESB, que classifica estas águas como de qualidade mediana. Os resultados confirmam também as vantagens deste índice, observadas em estudos anteriores, sobretudo quanto à capacidade de identificar as variáveis de qualidade de água que são mais determinantes para o resultado final do Índice, através do estudo dos subíndices.

Weather index insurance: Lessons learned and best practices for Bangladesh

WorldFish and the International Centre for Climate Change and Development (ICCCAD) held a two-day workshop on the topic of Weather Index-Based Insurance: Lessons Learned and Best Practices for Bangladesh. Weather index insurance is based on a predefined weather event which when triggered ensures automatic payout to farmers who have taken out insurance. For example, the climatic trigger could be a predefined consecutive number of days where rainfall is below a set level or when the floodwater level reaches above a certain point. Index insurance has been operating for about 10 years in many countries but is still at an early stage in Bangladesh, where there are two schemes currently being piloted and three other projects being developed. The aim of the two-day workshop was twofold: to ascertain the present state of index insurance in Bangladesh and elsewhere, and to work together to identify ways forward.

mHealth and global mental health: still waiting for the mH2 wedding?

BACKGROUND: Two phenomena have become increasingly visible over the past decade: the significant global burden of disease arising from mental illness and the rapid acceleration of mobile phone usage in poorer countries. Mental ill-health accounts for a significant proportion of global disability-adjusted life years (DALYs) and years lived with disability (YLDs), especially in poorer countries where a number of factors combine to exacerbate issues of undertreatment. Yet poorer countries have also witnessed significant investments in, and dramatic expansions of, mobile coverage and usage over the past decade. DEBATE: The conjunction of high levels of mental illness and high levels of mobile phone usage in poorer countries highlights the potential for "mH(2)" interventions--i.e. mHealth (mobile technology-based) mental health interventions--to tackle global mental health challenges. However, global mental health movements and initiatives have yet to engage fully with this potential, partly because of scepticism towards technological solutions in general and partly because existing mH(2) projects in mental health have often taken place in a fragmented, narrowly-focused, and small-scale manner. We argue for a deeper and more sustained engagement with mobile phone technology in the global mental health context, and outline the possible shape of an integrated mH(2) platform for the diagnosis, treatment, and monitoring of mental health. SUMMARY: Existing and developing mH(2) technologies represent an underutilised resource in global mental health. If development, evaluation, and implementation challenges are overcome, an integrated mH2 platform would make significant contributions to mental healthcare in multiple settings and contexts.

Trapping of low-refractive-index particles with azimuthally polarized beam

Azimuthally polarized beams, focused by a high-numerical-aperture (NA) objective lens, form a hollow intensity distribution near the focus, which is appropriate for trapping low-refractive-index particles, in contrast to common linearly polarized or radially polarized beams. In this paper, the field distribution of the azimuthally polarized beam focused by a high-NA objective is described by the vectorial diffraction integral, and then the radiation forces on spherical particles with different parameters such as radius and refractive index are calculated by the T-matrix method. Numerical results show that the azimuthally polarized beam not only can steadily trap low-refractive-index particles at the focus center but also can trap multiple high-refractive-index particles around the focus center by virtue of the hollow-ring configuration. The range of the sizes of low-refractive-index particles that can be trapped steadily are presented, corresponding to different parameters such as the NA of the objective and the relative refractive index, based on which the NA of the objective can be selected to trap the appropriate size of particles.

An Examination of the Use of Coercion by Assertive Outreach and Community Mental Health Teams in Northern Ireland.

In mental health services over recent decades, the positive move away from hospital-based care to community-based services has entailed that people with higher levels of need are being supported by community mental health services. This paper begins by reviewing the literature on coercion in the field of community-based mental health care and treatment. It is argued that the lack of a critical understanding of the concept and how it is used by practitioners and agencies can have serious repercussions for the rights of service users. Using a quasi-experimental, longitudinal design, the authors then seek to test some of the ideas about coercion by comparing the activities of assertive outreach and community mental health teams in Northern Ireland, particularly the key ideas of perceived coercion, workers’ strategies and engagement with services. Key findings were that assertive outreach appeared to be more successful at reducing perceived coercion, minimizing the need for coercive strategies, engaging high-risk clients and reducing inpatient bed use. These findings are compared with other studies in this area. The authors also argue that there is a need for greater transparency in the way that practitioners use coercive measures and more explicit guidance is required in this crucial area of mental health practice.

Obesity in People with Learning Disabilities: the impact of nurse led health screenings and health promotion activities

Background. Obesity appears to be more common among people with intellectual disabilities, with few studies focusing on achieving weight reduction. Aim. Firstly, to follow up people identified as overweight and obese following special health screening clinics and to determine the actions taken. Secondly, to evaluate the impact of health promotion classes on participants' weight loss. Methods. A clinic led by two learning disbaility nurses was held for all people aged 10 years and over (n=464) who attended special services within the area of one Health and Social Services Trust in Northern Ireland. In a second study, the nurses organised health promotion classes for 20 people over a 6 - 8 week period. Findings. The health screen identified 64% of adults and 26% of 10 - 19 year olds as being overweight or obese. Moreover, those aged 40 - 49 years who were obese had significantly higher levels of blood pressure. However, information obtained from a follow up questionnaire sent after 3 months suggested that of the 122 people identified for wiehgt reduciton, action had been taken for only 34% of them and only three were reported to have lost weight. The health promotion classes, however, led to a significant reduction in weight and body mass index scores. Conclusion. Health screening per se has limited impact on reducing obesity levels in this client group. Rather, health personnel such as general practitioners, nurses and health promotion staff need to work in partnership with service staff, carers and people with intellectual disabiltieis to create more active lifestyles.

Recognising the co-occurance of domestic and child abuse: a comparison of community and hospital-based midwives

This study aimed to compare and contrast how midwives working in either hospital or community settings are currently responding to the cooccurrence of domestic and child abuse (CA), their perceived role and willingness to identify abuse, record keeping, reporting of suspected or definite cases of CA and training received. A survey questionnaire was sent to 861 hospital and community midwives throughout Northern Ireland which resulted in 488 midwives completing the questionnaire, leading to a 57% response rate. Comparisons were made using descriptive statistics and cross-tabulation, and the questionnaire was validated using exploratory factor analysis. Community midwives reported receiving more training on domestic and CA. Although a high percent of both hospital and community midwives acknowledged a link between domestic violence (DV) and CA, it was the community midwives who encountered more suspected and definite (P <0.001) cases of CA. More community midwives reported to be aware of the mechanisms for reporting CA. However, an important finding is that although 12% of community midwives encountered a definite case of CA, only 2% reported the abuse, leaving a 10% gap between reporting and identifying definite cases of CA. Findings suggest that lack of education and training was a problem as only a quarter of hospital-based midwives reported to have received training on DV and 40% on CA. This was significantly less than that received by community midwives, as 57% received training on DV, and 62% on CA. The study suggests that midwives need training on how to interact with abused mothers using non-coercive, supportive and empowering mechanisms. Many women may not spontaneously disclose the issues of child or domestic abuse in their lives, but often respond honestly to a sensitively asked question. This issue is important as only 13% of the sample actually asked a woman a direct question about DV.

Mental Health nurses' attitudes towards personality disorder

The importance of the impact of nurses views towards personality disorder and their place in acute mental health environments are surveyed.A total of 49 registrants were surveyed all with at least one years experience and all on part one of the active register. Overall 66% of respondents did not feel that patients with a personality disorder should be treated in an acute inpatient setting, with only 36% reporting feeling confident in their abilities when working with this patient group. Almost all respondents 98% called for more training which the authors feel is a positive reflection on the profession.

Accessibility and Health: Towards Walkability Tools for Planning Practice

There is increasing research interest in how we can most effectively intervene in the built environment to change behaviours such as physical activity and improve health. Much of this work has focussed around the concept of walkability and the identification of those attributes of our cities that encourage pedestrian activity, including density, connectivity and the aesthetic of the urban realm (Saelens et al 2003, Frank et al 2010). Much of the existing research has clarified the strength of the relationships between various environmental attributes and the differential impact on different demographic groups (e.g. Panter et al 2011). This has not yet been effectively translated into tools to help integrate the concepts of walkability into decision-making by statutory authorities that can help shape the spatial development and delivery of public services which can support more active lifestyles. A key reason for this has been that standard models for transport planning and accessibility are based on networks of road infrastructure, which provides a weak basis for modelling pedestrian accessibility (Chin et al 2008).

This paper reports the findings of Knowledge Exchange project funded by UK’s Economic and Social Research Council (ES/J010588/1) and partners including Belfast and Derry City Councils and Northern Ireland’s Public Health Agency, the Department of Regional Development and Belfast Healthy Cities, that has attempted to address this problem. This project has mapped city-wide footpath networks and used these to assist partner organisations in developing the evidence base for making decisions on public services based on health impacts and pedestrian access. The paper describes the tool developed, uses a number of examples to highlight its impact on areas of decision-making and evaluates the benefits of further integrating walkability into planning and development practice.

First steps: study protocol for a randomized controlled trial of the effectiveness of the Group Family Nurse Partnership (gFNP) program compared to routine care in improving outcomes for high-risk mothers and their children and preventing abuse

Background: Evidence from the USA suggests that the home-based Family Nurse Partnership program (FNP), extending from early pregnancy until infants are 24 months, can reduce the risk of child abuse and neglect throughout childhood. FNP is now widely available in the UK. A new variant, Group Family Nurse Partnership (gFNP) offers similar content but in a group context and for a shorter time, until infants are 12 months old. Each group comprises 8 to 12 women with similar expected delivery dates and their partners. Its implementation has been established but there is no evidence of its effectiveness.

Methods/Design: The study comprises a multi-site randomized controlled trial designed to identify the benefits of gFNP compared to standard care. Participants (not eligible for FNP) must be either aged <20 years at their last menstrual period (LMP) with one or more previous live births, or aged 20 to 24 at LMP with low educational qualifications and no previous live births. 'Low educational qualifications' is defined as not having both Maths and English Language GCSE at grade C or higher or, if they have both, no more than four in total at grade C or higher. Exclusions are: under 20 years and previously received home-based FNP and, in either age group, severe psychotic mental illness or not able to communicate in English. Consenting women are randomly allocated (minimized by site and maternal age group) when between 10 and 16 weeks pregnant to either to the 44 session gFNP program or to standard care after the collection of baseline information. Researchers are blind to group assignment. The primary outcomes at 12 months are child abuse potential based on the revised Adult-Adolescent Parenting Inventory and parent/infant interaction coded using the CARE Index based on a video-taped interaction. Secondary outcomes are maternal depression, parenting stress, health related quality of life, social support, and use of services.

Discussion: This is the first study of the effectiveness of gFNP in the UK. Results should inform decision-making about its delivery alongside universal services, potentially enabling a wider range of families to benefit from the FNP curriculum and approach to supporting parenting.

Lung Clearance Index Is a Repeatable and Sensitive Indicator of Radiological Changes in Bronchiectasis

RATIONALE: In bronchiectasis there is a need for improved markers of lung function to determine disease severity and response to therapy.

OBJECTIVES: To assess whether the lung clearance index is a repeatable and more sensitive indicator of computed tomography (CT) scan abnormalities than spirometry in bronchiectasis.

METHODS: Thirty patients with stable bronchiectasis were recruited and lung clearance index, spirometry, and health-related quality of life measures were assessed on two occasions, 2 weeks apart when stable (study 1). A separate group of 60 patients with stable bronchiectasis was studied on a single visit with the same measurements and a CT scan (study 2).

MEASUREMENTS AND MAIN RESULTS: In study 1, the intervisit intraclass correlation coefficient for the lung clearance index was 0.94 (95% confidence interval, 0.89 to 0.97; P < 0.001). In study 2, the mean age was 62 (10) years, FEV1 76.5% predicted (18.9), lung clearance index 9.1 (2.0), and total CT score 14.1 (10.2)%. The lung clearance index was abnormal in 53 of 60 patients (88%) and FEV1 was abnormal in 37 of 60 patients (62%). FEV1 negatively correlated with the lung clearance index (r = -0.51, P < 0.0001). Across CT scores, there was a relationship with the lung clearance index, with little evidence of an effect of FEV1. There were no significant associations between the lung clearance index or FEV1 and health-related quality of life.

CONCLUSIONS: The lung clearance index is repeatable and a more sensitive measure than FEV1 in the detection of abnormalities demonstrated on CT scan. The lung clearance index has the potential to be a useful clinical and research tool in patients with bronchiectasis.

Recruiting schools, adolescents and parents to a sexual-health trial: experiences, challenges and lessons learned from the Jack Trial

Background
Recruitment to school-based randomised trials is challenging; even more so when the focus of the study is a sensitive issue such as sexual health. The Jack Feasibility Trial aims to determine the facilitators and barriers to recruitment and retention to a school-based sexual health trial and identify optimal multi-level strategies for a full trial.
Method
The Jack Trial is an NIHR-funded feasibility study of a film-based sexual health intervention, recruiting over 800 adolescents from 8 post-primary schools in Northern Ireland. In order to examine the feasibility of piloted recruitment and retention methods and assess acceptability of participation across the range of schools and individuals approached, we analysed qualitative data from triangulated sources including a parents’ survey and semi-structured interviews with principals, vice-principals, teachers and parents recruited to the study.
Results
With reference to Social Learning Theory, we identified a number of individual, behavioural and environmental level factors which influenced recruitment and retention. Commonly identified facilitators included the perceived relevance and potential benefit of the intervention to adolescents, the credibility of the organisation running the study, support offered by trial staff, and financial incentives. Key barriers were prior commitment to other research, lack of time and resources, and perceptions that the intervention was incompatible with adolescent needs or school ethos.
Conclusion
This study highlights pertinent general and trial-specific facilitators and barriers to recruitment to a sexual health trial in a school setting, which will prove useful for successful conduct of future trials with schools, adolescents and parents.

Implementation progress of mental health services in Rwanda: Bugesera district case

RESUMO: O Ministério da Saúde do Governo do Ruanda identifica a saúde mental como uma área de prioridade estratégica para a intervenção em resposta à alta carga dos transtornos mentais no Ruanda. Ao longo dos últimos 20 anos após o genocídio, o sector público reconstruiu sua Resposta Nacional de Saúde Mental com base no acesso equitativo aos cuidados, através do desenvolvimento de uma Política Nacional de Saúde Mental e novas estruturas de saúde mental. A política de Saúde Mental do Ruanda, revista em 2010, prima pela descentralização e integração dos serviços de saúde mental em todas as estruturas nacionais do sistema de saúde e ao nível da comunidade. O presente estudo de caso tem como objetivo avaliar a situação do sistema de saúde mental de um distrito típico de uma área rural no Ruanda, e sugerir melhorias, incluindo algumas estratégias para monitoras as mudanças. Os resultados do estudo permitirão ao Ruanda reforçar a sua capacidade para implementar o Plano Nacional de Saúde Mental ao nível dos distritos. O relatório também será útil para monitorar o progresso da implementação de serviços de saúde mental nos distritos, incluindo a prestação de serviços de base comunitária e a participação dos usuários, suas famílias e outros interessados na promoção, prevenção, assistência e reabilitação em saúde mental. Este estudo também procurou avaliar o progresso da implementação dos cuidados de saúde mental a nível descentralizado, com vista a compreender as implicações em termos de recursos desses processos. Foi realizada uma análise situacional num local do distrito, baseado em entrevistas com as principais partes interessadas responsáveis, usando o Instrumento de Avaliação de Sistemas de Saúde Mental da Organização Mundial da Saúde (WHO-AIMS). Os resultados sugerem que os recursos humanos para a saúde mental e serviços de base comunitária de saúde mental no distrito continuam a ser extremamente limitados. Os profissionais de saúde mental são adicionalmente limitados na sua capacidade para oferecer intervenções de emergência a pacientes psiquiátricos e garantir a continuidade do tratamento farmacológico a pacientes com condições crônicas. Para planejar efetivamente, de acordo com as necessidades da comunidade, sugerimos que o sistema de saúde mental deve envolver também os representantes das famílias e dos usuários no processo de planificação de modo a melhorar a sua contribuição no processo de implementação das atividades de saúde mental. Este estudo de caso do Distrito de Bugesera oferece a primeira análise de nível distrital dos serviços de saúde mental no Ruanda, e pode servir como uma mais-valia para a melhoria do sistema de saúde mental, incluindo a advocacia para a melhoria da qualidade dos cuidados de saúde mental a este nível, aumentando o financiamento para a implementação de serviços clínicos de saúde mental e os recursos humanos disponíveis para a prestação de cuidados de saúde mental, principalmente a nível dos cuidados primários.--------------------- ABSTRACT: To deal with the high burden of mental health disorders resulting from consequences of the 1994 genocide against Tutsis, the Rwanda Ministry of Health (MoH) considers mental health as a priority intervention. For the last 20 years, Ministry of Health focused on rebuilding a national and equity-oriented mental health program responding to the population needs in mental health. Mental health services are now decentralized and integrated in the national health system, from the community level up to the referral level. This study assessed the situation of mental health services in one rural district in Rwanda. It was aimed at assessing the progress of implementation of mental health care at the decentralized level, focusing on resource implications and processes. This study is based on interviews conducted with key stakeholders, using the World Health Organization's Assessment Instrument for Mental Health Systems (WHO-AIMS). Findings show that human resources for mental health care and community-based mental health services of the assessed district remain extremely limited. Mental health professionals face limitation regarding the ability to provide emergency management of psychiatric patients and to ensure continuity of psychopharmacological treatment of patients with chronic conditions. To improve the implementation process of mental health interventions and activities, a planning process based on community needs and the involvement of representatives of families and users in planning process should be considered. The Bugesera case study on the situation of mental health services can serve as a baseline for improvement of the mental health program in Rwanda, in terms of quality care services, infrastructure and equipment, human and financial resources.
