An evaluation of tobacco brief intervention training in three Indigenous health care settings in north Queensland

Objective: To evaluate the pilot phase of a tobacco brief intervention program in three Indigenous health care settings in rural and remote north Queensland. Methods: A combination of in-depth interviews with health staff and managers and focus groups with health staff and consumers. Results: The tobacco brief intervention initiative resulted in changes in clinical practice among health care workers in all three sites. Although health workers had reported routinely raising the issue of smoking in a variety of settings prior to the intervention, the training provided them with an additional opportunity to become more aware of new approaches to smoking cessation. Indigenous health workers in particular reported that their own attempts to give up smoking following the training had given them confidence and empathy in offering smoking cessation advice. However, the study found no evidence that anybody had actually given up smoking at six months following the intervention. Integration of brief intervention into routine clinical practice was constrained by organisational, interpersonal and other factors in the broader socio-environmental context. Conclusions/implications: While modest health gains may be possible through brief intervention, the potential effectiveness in Indigenous settings will be limited in the absence of broader strategies aimed at tackling community-identified health priorities such as alcohol misuse, violence, employment and education. Tobacco and other forms of lifestyle brief. intervention need to be part of multi-level health strategies. Training in tobacco brief intervention should address both the Indigenous context and the needs of Indigenous health care workers.

Risk factors and prevalence of antibodies against hepatitis A virus (HAV) in children from day-care centers, in Goiania, Brazil

A seroepidemiologic survey about hepatitis A virus (HAV) infection was carried out in a group comprising 310 children, ranging in age from 3 months to 9 years, from day-care centers, in Goiania, a middle sized city in the central region of Brazil. The biomarkers employed in the investigation of previous infection include total IgG and IgM anti-HAV antibodies, and for the detection of more recent infection, IgM anti-HAV antibodies were analyzed. The study was performed in 1991 and 1992. According to the results, 69.7% of the children presented total IgG/IgM anti-HAV antibodies, with 60% of the group in the age range of 1 to 3 years. Among 10 day-care centers analyzed, the prevalence of the biomarker IgM anti-HAV was 3.2%, with an uniform distribution of the cases in the group of children ranging in age from 1 to 4 years. Multi-variate analysis was performed to investigate the sociodemographic factors that could influence the results. It was verified that the risk for the infection increased with the length of the attendance in the day-care centers, i.e., the risk for children with attendance of one year or more was 4.7 times higher, when compared with children with one month attendance (CI 95% 2.3-9.9). According to the results, hepatitis A is an endemic infection in day-care centers in the study area. The length of attendance in the day-care settings was demonstrated to be a risk factor for the HAV infection. Such findings suggest that if hepatits A vaccination becomes available as a routine policy in our region, the target group should be children under one year. Moreover, those children should receive the vaccine before they start to attend the day-care centers.

Os sistemas de informação geográfica e a análise multicritério para o estudo da acessibilidade e mobilidade da rede escolar no município da Humpata (Angola)

O presente trabalho faz uma abordagem aos Sistemas de Informação Geográfica (SIG) e a análise multicritério (AMC) para o estudo da acessibilidade da rede escolar do município de Humpata, província da Huíla, situada em Angola. Neste trabalho pretende-se demonstrar as dificuldades de acessibilidade e mobilidade tendo em conta aos principais factores que condicionam a rede escolar e também a acessibilidade em termos de oferta e recursos, analisando com algum pormenor as condições de ensino que as escolas oferecem. Por outro lado foram também elaborados modelos de velocidade com o objectivo de verificar a distância-tempo percorrida pelos usuários considerando o declive do terreno. Ficou demonstrado que, para o estudo da acessibilidade da rede escolar, o uso dos SIG e a AMC fornecem resultados com relevância na tomada de decisão. A AMC conjugada com a álgebra de mapas, permitiu registar as disparidades de acessibilidade entre diferentes povoações que compõem o município. Aconselha-se por isso a utilização de ferramentas de análise espacial como os SIG, em contextos como o do município de Humpata onde os recursos escassos devem ser bem geridos, de forma a levar os serviços públicos e privados à maior parte da população e às povoações que mais necessitam através da localização óptima dos futuros serviços, que no caso das instituições escolares concorrera para garantia do sucesso escolar.

Correlates of intergenerational mobility and political violence

This work project aims at exploring the role of intergenerational immobility in political violence. A cross-country macro-level analysis is done where no significant results are found. Additionally, an individual micro-level analysis is done where intergenerational mobility (measured through a proxy variable) has a negative significant effect in political violence

Cell functional enviromics: applications to Pichia pastoris

The present PhD thesis develops the cell functional enviromics (CFE) method to investigate the relationship between environment and cellular physiology. CFE may be defined as the envirome-wide cellular function reconstruction through the collection and systems-level analysis of dynamic envirome data. Throughout the thesis, CFE is illustrated by two main applications to cultures of a constitutive P. pastoris X33 strain expressing a scFv antibody fragment. The first application addresses the challenge of culture media development. A dataset was built from 26 shake flask experiments, with variations in trace elements concentrations and basal medium dilution based on the standard BSM+PTM1. Protein yield showed high sensitivity to culture medium variations, while biomass was essentially determined by BSM dilution. High scFv yield was associated with high overall metabolic fluxes through central carbon pathways concomitantly with a relative shift of carbon flux from biosynthetic towards energy-generating pathways. CFE identified three cellular functions (growth, energy generation and by-product formation) that together described 98.8% of the variance in observed fluxes. Analyses of how medium factors relate to identified cellular functions showed iron and manganese at concentrations close to PTM1 inhibit overall metabolic activity. The second application addresses bioreactor operation. Pilot 50 L fed-batch cultivations, followed by 1H-NMR exometabolite profiling, allowed the acquisition of data for 21 environmental factors over time. CFE identified five major metabolic pathway groups that are frequently activated by the environment. The resulting functional enviromics map may serve as template for future optimization of media composition and feeding strategies for Pichia pastoris. The present PhD thesis is a step forward towards establishing the foundations of CFE that is still at its infancy. The methods developed herein are a contribution for changing the culture media and process development paradigm towards a holistic and systematic discipline in the future.

Humble leadership and team voice

This study examines the direct and indirect effects of humble leadership on team voice. Although the relationship between leadership styles and voice is widely investigated, humble leadership and team voice, both relatively new constructs, remained out of sight. Drawing upon social interdependence theory, information exchange, team psychological safety, and team-efficacy are proposed to mediate the relationship between humble leadership and team voice. Research is conducted at the team-level analysis and involved 209 team members from 52 teams in 21 companies collected through a snowball sample. Results were provided by the SPSS macro PROCESS using the regression-based approach and bootstrapping techniques. Findings showed that humble leadership is positively related to team voice. Furthermore, findings supported the mediating effect of information exchange. However, no support was given for the mediating effects of team psychological safety and team-efficacy. Theoretical and practical implications of the findings are addressed.

Envolvimento parental no desporto

O presente conjunto de investigações pretendeu estudar o envolvimento parental na competição desportiva de crianças e jovens. Baseado no modelo do envolvimento parental no desporto (Teques & Serpa, 2009), o estudo permitiu concretizar dois objectivos fundamentais. Primeiro, desenvolver um conjunto de escalas válidas e fidedignas para aceder aos constructos incluídos no modelo teórico. Segundo, testar as hipóteses fundamentadas na estrutura conceptual do modelo com o propósito de compreender (1) a razão porque os pais se envolvem no desporto dos filhos, (2) quais os comportamentos utilizados pelos pais durante o envolvimento, e (3) como é que o envolvimento influencia o contexto de realização do jovem atleta. No total, participaram voluntariamente 1620 pais e 1665 jovens atletas de vários desportos individuais e coletivos, com idades compreendidas entre os 9 e os 18 anos. A prossecução dos objectivos teve por base uma série de três estudos independentes. Os resultados do primeiro estudo sugerem que as crenças do papel parental, a auto-eficácia, a perceção das invocações oriundas do treinador e do jovem atleta, o tempo e energia disponíveis, e os conhecimentos e competências relacionam-se com as atividades de envolvimento dos pais. No segundo estudo, os resultados demonstraram que as perceções dos comportamentos parentais de encorajamento, reforço, instrução, e modelagem medeiam a relação entre os comportamentos reportados pelos pais e as variáveis psicológicas de auto-eficácia, auto-eficácia social, motivação intrínseca, e estratégias de autorregulação dos jovens. Os resultados do terceiro estudo indicam que as perceções dos comportamentos dos pais relacionam-se com a realização desportiva através dos efeitos de mediação da auto-eficácia, autoeficácia social e das estratégias de autorregulação. Implicações para a intervenção, limitações e direções futuras para a investigação são também discutidas.

What is the european social model? an aproximation based on Spanish case

The public perception of the EU in Spain varies greatly. The most positive aspects of Spanish membership are associated with the consolidation of democracy, economic growth, the introduction of the euro, the growth in employment and structural and cohesion funds, the increase in the female participation rate, and the equal opportunities policies. The analysts are in favour of common objectives in the employment policy and multi-level government. The less positive aspects of the EU are the risks of losing social protection and loss of employment in some sectors due to mergers of multinationals and delocalization of companies towards Eastern Europe. The continuous demands for reform of the welfare state, the toughening of the conditions of access to social benefit and the reform of the labour market are also seen as problematic issues. Risks of competitive cuts and social dumping.

Public Sector Pay in Finland

This study analyses the forces determining public and private sector pay in Finland. The data used is a 7 per cent sample taken from the Finnish 2001 census. It contains information on 42 680 male workers, of which 8 759 are employed in public and 33 921 in the private sector. The study documents and describes data by education, occupation and industry. We estimate earnings equations for the whole sample as well as for four industries (construction, real estate, transportation and health) that provide an adequate mix of both public and sector workers. The results suggest that the private-public sector pay gap of about one per cent can be accounted for by differences in observable characteristics between the sectors (3.4 per cent) and lower returns from these characteristics (-2.3 per cent). However, the industry-level analysis indicates that the earnings gaps vary across industries, and are negative in some cases. These inter-industry differences in public-private gaps persist even when the usual controls are introduced. This suggests that public sector wage setters need greater local flexibility, which should result in less uniform wages within the public sector.
