The role of qualitative data and systems thinking in addressing service decline in market towns

Retail services are a main contributor to municipal budget and are an activity that affects perceived quality-of-life, especially for those with mobility difficulties (e.g. the elderly, low income citizens). However, there is evidence of a decline in some of the services market towns provide to their citizens. In market towns, this decline has been reported all over the western world, from North America to Australia. The aim of this research was to understand retail decline and enlighten on some ways of addressing this decline, using a case study, Thornbury, a small town in the Southwest of England. Data collected came from two participatory approaches: photo-surveys and multicriteria mapping. The interpretation of data came from using participants as analysts, but also, using systems thinking (systems diagramming and social trap theory) for theory building. This research moves away from mainstream economic and town planning perspectives by making use of different methods and concepts used in anthropology and visual sociology (photo-surveys), decision-making and ecological economics (multicriteria mapping and social trap theory). In sum, this research has experimented with different methods, out of their context, to analyse retail decline in a small town. This research developed a conceptual model for retail decline and identified the existence of conflicting goals and interests and their implications for retail decline, as well as causes for these. Most of the potential causes have had little attention in the literature. This research also identified that some of the measures commonly used for dealing with retail decline may be contributing to the causes of retail decline itself. Additionally, this research reviewed some of the measures that can be used to deal with retail decline, implications for policy-making and reflected on the use of the data collection and analysis methods in the context of small to medium towns.

Medium access control design for distributed opportunistic radio networks

Existing wireless networks are characterized by a fixed spectrum assignment policy. However, the scarcity of available spectrum and its inefficient usage demands for a new communication paradigm to exploit the existing spectrum opportunistically. Future Cognitive Radio (CR) devices should be able to sense unoccupied spectrum and will allow the deployment of real opportunistic networks. Still, traditional Physical (PHY) and Medium Access Control (MAC) protocols are not suitable for this new type of networks because they are optimized to operate over fixed assigned frequency bands. Therefore, novel PHY-MAC cross-layer protocols should be developed to cope with the specific features of opportunistic networks. This thesis is mainly focused on the design and evaluation of MAC protocols for Decentralized Cognitive Radio Networks (DCRNs). It starts with a characterization of the spectrum sensing framework based on the Energy-Based Sensing (EBS) technique considering multiple scenarios. Then, guided by the sensing results obtained by the aforementioned technique, we present two novel decentralized CR MAC schemes: the first one designed to operate in single-channel scenarios and the second one to be used in multichannel scenarios. Analytical models for the network goodput, packet service time and individual transmission probability are derived and used to compute the performance of both protocols. Simulation results assess the accuracy of the analytical models as well as the benefits of the proposed CR MAC schemes.

Future gender relations in global restructuring processes case study evidence from knowledge-intensive, manufacturing and service occupations

Global restructuring processes have not only strong implications for European working and living realities, but also have specific outcomes with regard to gender relations. The following contribution analyses in which way global restructuring shapes current gender relations in order to identify important trends and developments for future gender (in)equalities at the workplace. On the basis of a large qualitative study on global restructuring and impacts on different occupational groups it argues that occupational belonging in line with skill and qualification levels are crucial factors to assess the further development of gender relations at work. Whereas global restructuring in knowledge-based occupations may provide new opportunities for female employees, current restructuring is going to deteriorate female labour participation in service occupations. In contrast, manufacturing occupations can be characterised by persistent gender relations, which do not change in spite of major restructuring processes at the work place. Taking the institutional perspective into account, it seems to be crucial to integrate the occupational perspective in order to apply adequate policy regulations to prevent the reinforcement of gender related working patterns in the near future.

Characterization of cleaners accidents in the Portuguese service sector

This paper characterizes work accidents at Portuguese industrial cleaning companies, operating in the service sector, through the application of ESAW methodology. Data was codified based on the analysis of 748 accident claims to insurance companies (number of days lost 1 working day) in 3 large industrial cleaning companies for the period 2001-2003. Slipping and falling in the same level was the main deviation from the normal working process in the moment of the accident (in 25% of the accidents); uncoordinated movements was the second cause of accidents (14%); falls of persons to a lower level was the third cause of accidents (~10%), including falls from stairs (~7%) and falls from ladders and mobile ladders (~2%); globally, body movement under or with physical stress, including lifting, carrying, putting down, bending down, twisting, turning, trading badly, twisting leg or ankle and slipping without falling, were the cause in 17% of the accidents. Lower limbs were injured in ~25% of the accidents, hand and fingers in ~14%, the eye in ~4% and the back in ~9% of the accidents. An incidence rate of 3,580 accidents/100,000 employees was found to the sector (2003 data).

Estudo descritivo do perfil de utilizador da linha Saúde 24 com análise de impacto ao nível da eficiência, equidade e empowerment em comparação com o modelo inglês NHS Direct

RESUMO - A 8 de Maio de 2008 surgiu o centro de atendimento “Linha Saúde24” (S24) no sentido de modernizar o SNS, aproximando-o do cidadão. O serviço surge baseado no modelo inglês – o NHS Direct – que pode ser encarado como um serviço de informação telefónico apoiado por enfermeiros, disponível 24h por dia, concebido para expandir os serviços púbicos de acesso à rede prestadora de cuidados com intuito de aliviar a pressão da procura na rede de urgências hospitalares e médicos de família, assim como diluir as iniquidades regionais na prestação de serviços. A S24 assenta na perspectiva de ser um ponto de contacto inicial do utente com a rede de prestação de cuidados de saúde com capacidade de orientação. O objectivo da linha está na tentativa mais eficiente no uso dos recursos disponíveis, ao mesmo tempo que delega responsabilidade no cidadão na forma como este utiliza os recursos disponíveis, com melhor racionalização financeira na área da saúde aliada a uma melhor qualidade de serviço prestada e adequada, colocando os cidadãos no mesmo patamar, diluindo as dificuldades de acesso a aqueles que necessitam na tentativa de harmonizar e racionalizar o consumo de serviços de saúde. Esta estrutura permite ao cidadão conhecer melhor o seu estado de saúde e decidir mais acertadamente quanto à decisão a tomar. Com este estudo, e com base na literatura nacional e internacional, pretende-se descrever o perfil de utilizador que acede à S24 – definir o tipo de utilizador, disposição geográfica, motivos pelo qual acede ao serviço e qual o seu destino final, fazendo comparação com o perfil do NHS Direct. Assim, e com os dados obtidos, far-se-á uma avaliação preliminar em termos do contributo da linha S24 no que concerne à sua eficiência, equidade e empowerment dado ao utilizador. --- ------------------------------ABSTRACT - Saúde 24 (S24) is a national 24-hour health line initiated in May 2008 aiming at modernizing the Portuguese NHS by bringing it closer to the citizen. Indeed, S24 be seen as an initial contact point between the patient and the healthcare network, facilitating a better a management of health care demand. The service is inspired on the UK NHS Direct – a nurse-led telephone line to provide easier and faster advice information to people about health, illness and NHS services. It is expected to provide information so that people can deal with their health problems or their families´ on their own, with the purpose of reducing demand to A&E department and out-of-hours GP services. Additionally it can contribute to a reduction in regional inequities in healthcare provision through bringing health care advice to remote areas. The purpose of S24 is to handle more efficiently the available resources by enabling responsibilities in citizens. By doing so, S24 encourages a more appropriate use of available resources, with better financial outcomes and a better quality of care. It is meant, in terms of empowerment, to help people to be in control of their health and healthcare interactions by participating in the final decision. Based on quantitative data, this study defines the S24 caller user profile in terms of type, geographical reference, reasons for calling and outcome. This analysis allows us to perform a preliminary evaluation of the S24 in terms of its contribution to efficiency, equity and empowerment. Then the S24 is compared to
