Realist Evaluation: a theory driven approach.

Realistic Evaluation assumes that all programmes implemented in practice have an underlying theory to explain how a particular intervention is meant to work. The purpose of realist evaluation is to test the theoretical propositions underpinning the implementation of a programme in order to understand how and why it works, or might not work, in certain circumstances. The first stage of the realist evaluation is to track and articulate the programme theories to determine the evidence on the ‘official conjecture’ (Pawson et al 2004 pg 16) of how the programme is suppose to work in practice. These official conjectures are then tested and refined by gathering empirical evidence to establish causal relationships between a programme and its outcome. Evaluation of the factors and interactions between factors, supporting or hindering the implementation of a programme in practice facilitate theory refinement. Theory refinement is viewed as an iterative and cyclical process undertaken to synthesise the empirical evidence and develop mid-range theories which can be generalised and applied to other programmes to improve implementation and sustainability. In this symposium an example of realist evaluation used to test and refine the theory underpinning the implementation of Early Warning Systems (EWS) is provided to clarify how this theory driven approach can be applied in practice.

Electron-Impact Uncertainty Analysis and its Impact on Certain Temperature Diagnostics

In this study we calculate the electron-impact uncertainties in atomic data for direct ionization and recombination and investigate the role of these uncertainties on spectral diagnostics. We outline a systematic approach to assigning meaningful uncertainties that vary with electron temperature. Once these uncertainty parameters have been evaluated, we can then calculate the uncertainties on key diagnostics through a Monte Carlo routine, using the Astrophysical Emission Code (APEC) [Smith et al. 2001]. We incorporate these uncertainties into well known temperature diagnostics, such as the Lyman alpha versus resonance line ratio and the G ratio. We compare these calculations to a study performed by [Testa et al. 2004], where significant discrepancies in the two diagnostic ratios were observed. We conclude that while the atomic physics uncertainties play a noticeable role in the discrepancies observed by Testa, they do not explain all of them. This indicates that there is another physical process occurring in the system that is not being taken into account.

Carers and Co-Production: Enabling Expertise through Experience?

Purpose To provide a brief overview of the literature to date which has focussed on co-production within mental healthcare in the UK, including service user and carer involvement and collaboration. Design The paper presents key outcomes from studies which have explicitly attempted to introduce co-produced care in addition to specific tools designed to encourage co-production within mental health services. The paper debates the cultural and ideological shift required for staff, service users and family members to undertake co-produced care and outlines challenges ahead with respect to service redesign and new roles in practice. Findings Informal carers (family and friends) are recognised as a fundamental resource for mental health service provision, as well as a rich source of expertise through experience, yet their views are rarely solicited by mental health professionals or taken into account during decision-making. This issue is considered alongside new policy recommendations which advocate the development of co-produced services and care. Research Limitations Despite the launch of a number of initiatives designed to build on peer experience and support, there has been a lack of attention on the differing dynamic which remains evident between healthcare professionals and people using mental health services. Co-production sheds a light on the blurring of roles, trust and shared endeavour (Slay and Stephens, 2013) but, despite an increase in peer recovery workers across England, there has been little research or service development designed to focus explicitly on this particular dynamic. Practical Implications Despite these challenges, coproduction in mental healthcare represents a real opportunity for the skills and experience of family members to be taken into account and could provide a mechanism to achieve the ‘triangle of care’ with input, recognition and respect given to all (service users, carers, professionals) whose lives are touched by mental distress. However, lack of attention in relation to carer perspectives, expertise and potential involvement could undermine the potential for coproduction to act as a vehicle to encourage person-centred care which accounts for social in addition to clinical factors. Social Implications The families of people with severe and enduring mental illness (SMI) assume a major responsibility for the provision of care and support to their relatives over extended time periods (Rose et al, 2004). Involving carers in discussions about care planning could help to provide a wider picture about the impact of mental health difficulties, beyond symptom reduction. The ‘co-production of care’ reflects a desire to work meaningfully and fully with service users and carers. However, to date, little work has been undertaken in order to coproduce services through the ‘triangle of care’ with carers bringing their own skills, resources and expertise. Originality/Value This paper debates the current involvement of carers across mental healthcare and debates whether co-production could be a vehicle to utilise carer expertise, enhance quality and satisfaction with mental healthcare. The critique of current work highlights the danger of increasing expectations on service providers to undertake work aligned to key initiatives (shared decision-making, person-centred care, co-production), that have common underpinning principles but, in the absence of practical guidance, could be addressed in isolation rather than as an integrated approach within a ‘triangle of care’.

Adesão ao regime terapêutico na pessoa com enfarte agudo do miócardio: contributo dos enfermeiros no internamento hospita

RESUMO: O Enfarte Agudo do Miocárdio (EAM) representa um dos principais problemas de saúde pública em Portugal. A rápida intervenção nos factores de risco determinantes da saúde cardíaca pode ter um impacto positivo em vários indicadores de saúde. O objectivo final dessa intervenção passa por capacitar a pessoa, para que, autonomamente, adopte um conjunto de comportamentos de saúde, baseados em estilos de vida protectores da saúde cardíaca, que favorecem positivamente o processo de reabilitação. Esta procura e aquisição do comportamento de saúde, adesão ao regime terapêutico, deve ser desenvolvido em parceria com os profissionais de saúde. O hospital representa a porta de entrada da pessoa com EAM no sistema de saúde. É neste contacto que se inicia uma intervenção de sensibilização e promoção da adesão ao regime terapêutico. Sendo os enfermeiros um grupo profissional que estabelece uma relação continua com a pessoa, importa conhecer um conjunto de dimensões do desempenho dos enfermeiros na promoção da adesão ao regime terapêutico. Breve referência ao desenho de estudo. Foram incluídas no estudo 143 enfermeiros de 9 serviços hospitalares da Região de Saúde de Lisboa e Vale do Tejo. Os dados foram obtidos através de um questionário auto-preenchido. Os dados mostraram que a população de enfermeiros é jovem (M= 30,5: dp= 8,0), 49% têm uma idade £ 26 anos e apresenta pouca experiência profissional (M=7,7; dp= 7,6), 48,2% exerce a profissão há menos de 3 anos. A antiguidade no serviço actual é reduzida (M= 4,7; dp= 4,6), 48,9% estão no serviço há menos de 2 anos. Os enfermeiros acreditam que deviam intervir com mais frequência nos factores de risco fisiológicos e comportamentais que nos factores psicossociais e ambientais; a confiança que têm nas capacidades para intervir nos factores de risco fisiológicos e comportamentais é maior que nos factores psicossociais e ambientais e no último ano, intervieram mais frequentemente nos factores de risco fisiológicos e comportamentais que nos psicossociais e ambientais. O “ensaio” da validação da escala de Will scale de Anderson et al (2004), sobre a capacidade de intervenção na saúde cardíaca, mostrou que o teste de Esfericidade de Bartlett e Medida de adequação da amostragem de Kaiser-Meyer- Olkin (KMO) permitiram a realização da análise factorial em componentes principais (AFCP). Da AFCP emergiram 16 factores, os mesmos que no estudo original de Anderson et al (2004), que revelaram boa consistência interna, com valores de alpha de Cronbach que variaram entre 0,71 a 0,98. Os resultados revelam a necessidade de sensibilizar os enfermeiros para valorizar a intervenção no âmbito dos factores de risco psicossociais e ambientais para promover a adesão ao regime terapêutico. Sugerem ainda que a intervenção baseada na evidência pode ser potenciada de forma a melhorar as práticas de cuidados dos enfermeiros. ABSTRACT: Myocardial infarction (MI) is one of the most important problems in public health in Portugal. A prompt intervention in cardiac health determinants means a positive impact in health outcomes, individually and collectively. The main purpose of this intervention lays on patient’s empowerment so he or she becomes able to choose healthy behaviours, based on heart health protective life styles, and therefore to manage his/hers therapeutic regime. This search and acquisition of health behaviours leading to therapeutic regime adherence may positively have an influence on the whole rehabilitation process and it must be developed in partnership with health workers. MI patients’ first contact with the Health System usually happens at the Hospital. Here the first steps are taken to start an intervention in order to promote therapeutic regime adherence. Nurses are a group of health workers who establish a unique and continuous relation with patients, so it matters to have knowledge of their performance skills that can actually promote a healthy behaviours and increase therapeutic regime adherence. Short Study design The study sample includes 143 nurses working on 9 different hospital wards, belonging to the Lisboa and Tejo’s Valley Health Region, in the district of Lisbon. Data were collected trough a self-administered questionnaire. It revealed that the nurses sample is a young population (M=30,5; dp=8,0), 49% of whom are aged less than 26 years old and has little professional experience (M=7,7; dp= 7,6); 48,2% work has nurses for less than 3 years. There’s a low percentage of seniority (M=4,7; dp=4,6), 48,9% of nurses work in these wards for less than 2 years. Nurses believe they should have intervene more frequently in physiological and behaviour risk factors than in psychological, social and environmental factors; they have greater confidence in their ability to intervene in physiological and behaviour risk factors than to intervene in psychological, social and environmental factors. In last year they took interventions more frequently in physiological and behaviour risk factors than in the other health determinants. The Scale Validation “essay” on Will Scale (Anderson et al, 2004), about heart health intervention capacity, revealed that the Bartlett’s test sphericity and the Kaiser-Meyer- Olkin’s (KMO) appropriate sample measure allowed the factorial analysis on main components (FAMC). From FAMC emerged 16 factors, the same number found on Anderson’s et al (2004) study, revealing good internal consistence, with Cronbach’s alpha values that varied between 0,71 and 0,98. The results point a need for nurses to attribute bigger value to other health determinants intervention - such as psychological, social and environmental determinants - so they’ll take part in promoting therapeutic regime adherence. The results also suggest t

Medidas Fonológicas em Crianças com Perturbação dos Sons da Fala. Estudo comparativo entre o português europeu e o português brasileiro.

O objetivo deste estudo é comparar as características de dois grupos de crianças com diagnóstico de Perturbação dos Sons da Fala (PSF), falantes de português europeu (PE) e falantes de português brasileiro (PB), considerando um conjunto de medidas fonológicas que incluem Percentagem de Consoantes Corretas (PCC), Percentagem de Consoantes Corretas Revista (PCC-R), Process Density Index (PDI), Índices Absolutos (IA) e Índices Relativos (IR) de Substituição, Omissão e Distorção, tipos de Processos Fonológicos e Percentagem de Acerto por Fonema (PAF). Método: Neste estudo participaram dezoito crianças com diagnóstico de Perturbação dos Sons da Fala (PSF), com idades compreendidas entre os cinco anos e dois meses e os sete anos e 11 meses, sendo doze do sexo masculino e seis do sexo feminino, divididas em dois grupos - falantes de português europeu (GPE) e falantes de português brasileiro (GPB) - emparelhadas por idade, sexo e valor de PCC. A partir da análise das transcrições fonéticas constantes nas folhas de registo de cada subteste de nomeação de cada sujeito - Teste Fonético-Fonológico - Avaliação de Linguagem Pré-Escolar (TFF - ALPE) (Mendes et al., 2009) para o português europeu, e provas de fonologia do Teste de Linguagem Infantil ABFW (Andrade et al., 2004) para o português brasileiro,- foram calculadas e comparadas as medidas fonológicas referidas, recorrendo a testes estatísticos (paramétricos e não paramétricos). Resultados: O emparelhamento do GPE com o GPB foi bem sucedido. Não existiram diferenças estatísticamente significativas nas medidas fonológicas em estudo entre o GPE e o GPB. No Estudo 1, não existiram diferenças nos tipos de erros à exceção do erro de omissão. No Estudo 2, no GPE verificamos um menor número de erros de distorção e um maior número de erros de omissão. Existem algumas particularidades devido à variante da língua, nomeadamente no processo fonológico de PAL e de DESV. Conclusão: Esta investigação permitiu realizar a comparação do GPE e do GPB com a utilização de dois instrumentos recolha de dados diferentes. Os resultados foram de encontro ao que é descrito por outros estudos nesta área de investigação. As poucas diferenças que se observaram podem ser explicadas pelas diferenças existentes entre os sistemas fonético-fonológicos das duas variedades linguísticas. É extremamente importante a metodologia de recolha de dados para a avaliação das PSF. A mais valia desta pesquisa é o contributo de indicadores clínicos para diagnóstico, prognóstico e intervenção terapêutica nas PSF.

Creating and Enabling a Sustainable Livelihood for Persons with Intellectual Disabilities: A Comparative Case Study of Ghana and Canada.

Abstract Despite the plethora of published studies on rights, including employment rights, for persons with intellectual disabilities (Hatton, 2002; Tarulli, et al., 2004; Ward & Stewart, 2008), relatively few have discussed their applicability to individuals with intellectual disabilities to facilitate their full involvement in socio-economic development. This study explored the mechanisms facilitating and inhibiting the full participation of persons with intellectual disabilities in the area of employment through a comparative case analysis of policies and practices in Ontario, Canada (a developed country) and in Ghana (a developing country) both of which are signatories to the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD). The study employed targeted recruitment based on the nature of the research which is a combination of policy and practice investigation.

The Discourse of Home Recording : Accessibility, Exclusion and Power

Ce mémoire propose une analyse critique du discours de l’enregistrement sonore à domicile (home recording). Dans la foulée des propos mettant de l’avant l’ «accessibilité» et la «démocratisation» de l’enregistrement sonore, ce mémoire analyse les relations de savoir/pouvoir produites et légitimées par le discours, ce qu’elles permettent et contraignent, autorisent et excluent. Le corpus à l’étude est issu de la presse musicale ainsi que de forums de discussion en ligne relevant de sites spécialisés. Les méthodes utilisées sont inspirées de l’approche du discours développées par Michel Foucault et de ce que Johnson et. al. (2004) appellent l’interprétation critique. L’analyse met en évidence les deux principaux sujets du discours de l’enregistrement sonore à la maison : les professionnels de l’enregistrement et les «pros» de l’enregistrement à domicile, deux groupes constitués d’hommes financièrement aisés. Les règles qui régissent l’enregistrement à domicile semblent reprendre, en les adaptant, celles régissant les studios professionnels. Ce mémoire suggère que la «démocratisation» telle qu'énoncée dans ce discours articule l'«accessibilité contemporaine» à certains savoirs et certaines technologies à des exclusions singulières – comme des femmes et des personnes de moyens limités – qui rendent ce discours possible. Être dans le vrai, dans ce discours, c’est échanger, argumenter, discuter et prescrire des façons de faire et de dire qui font des studios professionnels l’espace des normes et des légitimités. Mots clés: enregistrement, musique, maison, domicile, studio, démocratisation, technologie, l'analyse du discours, relations de pouvoir/savoir, Michel Foucault.

Application of Biofloc Technology (BFT) in the nursery rearing and farming of giant freshwater prawn, Macrobrachium rosenbergii (deMan)

In India a study conducted by CIFE and CIBA (1997), concluded that shrimp farming does more good than harm and it is not eco-unfriendly (Krishnan and Birthal, 2002). Upsurge in coastal aquaculture activity induced by high profitability is reported to have caused adverse impacts on coastal ecosystems and social environments (Parthasarathy and Nirmala, 2000). The crustacean farming sector has received criticism for excessive use of formulated feed containing high protein, of which around 50% gets accumulated at the pond bottom as unconsumed (Avnimelech, 1999; Hari et al., 2004, 2006). The wasted feeds undergo the process of degradation and results in the release of toxic metabolites to the culture system. Reduction of protein in the feed, manipulation and utilisation of natural food in the culture system are the remedy for the above problems. But before reducing the feed protein, it should be confirmed that the feed with reduced protein is not affecting the growth and health of the cultured animal. In the present study, biofloc technology is identified as one of the innovative technologies for ensuring the ecological and environmental Sustainability and examines the compatibility of BFT for the sustainable aquaculture of giant prawn, M. rosenbergii. This thesis starts with a general introduction (Chapter-1), a brief review of the most relevant literature (Chapter-2), results of various experiments (Chapter-3-6), summary (Chapter-7) and recommendations and future research perspectives in the field of biofloc based aquaculture (Chapter – 8). The major objectives of this thesis are, to improve the ecological and economical sustainability of prawn farming by the applicationof BFT and to improve the nutrient utilisation in aquaculture systems.
