El proyecto de investigación se dirige a sistematizar un abordaje postfundacionalista de las identidades políticas en vistas a la construcción de un marco teórico-metodológico para el análisis histórico-político. Se parte de la creciente relevancia en las ciencias sociales de la cuestión de la “identidad” para indagar la singularidad del marco teórico adoptado en su estudio. Así, el postfundacionalismo da cuenta de una teoría de las subjetividades políticas que parte de procesos de identificación que suponen una articulación singular entre relativa estructuralidad y agencia. El sujeto emerge en un contexto nunca plenamente suturado ni plenamente abierto, sino a través de un anudamiento de diversas dimensiones reales, simbólicas e imaginarias. Esta visión es altamente productiva para generar conclusiones relevantes en el campo de la ciencia política y del análisis histórico político comparado. This research project seeks to systematise from a postfundationalist view of political identities a theoretico-methodological framework for historico political analysis. The project starts from the increasing relevance of the quistion of 'identity' for contremporary social sciences. Poststructuralism provides an insight of processes of identification that supposes a singular articulation between relative structurality and agency. The subject emerges in a neither fully structured nor fully opened context but through a knotting process of different registers: real, symblic and imaginary. This vision, we believe, is highly productive to generate meaningful conclusions in the field of political science and comparative political analysis.

This thesis investigates the challenges of establishing the electric vehicle (EV) in Ireland and how the Irish government and industry are trying to meet them. It further seeks to provide information on Irish consumers’ attitudes towards the electric vehicle and their willingness to purchase it. The review of the literature showed that the Irish government is investing significant funds in trying to establish the market for the electric vehicle and position itself as a world leader in adopting the electric vehicle. The EV will also have an important role to play in how Ireland meets its targets for CO2 reductions towards 2020. Climate change and use of fossil fuels are driving the need for increased use of renewable energy and increased energy independence while reducing the greenhouse gas emissions that are the leading cause of climate change. The transport sector is almost completely dependent on the use of fossil fuel and resultantly is one of the largest sources of these GHG emissions. These issues are leading to the design and production of more energy efficient and environmentally friendly vehicles. The ultimate goal is to achieve a zero emissions vehicle. The electric vehicle is presently the only vehicle being mass produced that has the potential to be zero emissions. There are however issues that customers may not be willing to overlook such as the lower range of the vehicle and the length of time it takes to recharge. Vehicle cost is also an important issue that customers may not overlook. Knowing what the consumer’s attitudes are towards the EV and their willingness to purchase them is important as these new vehicles begin to appear in the showrooms. The consumers will be vital to how successful this market becomes. Using an online questionnaire methodology, in a sample of 118 consumers, the major conclusion to be drawn from the research is that the vehicle price, the convenience to recharge and vehicle range were the three most essential issues for the consumers if they were purchasing an EV. The success of the electric vehicle market may depend on what measures are taken to overcome them.

En la recerca s’expliquen els resultats de la implementació d’un programa adreçat bàsicament al treball de la consciència emocional de l’intern penitenciari i la regulació d’aquesta consciència. El motiu és que en el plantejament teòric es parteix de les constatacions de molts autors que els programes que millor funcionen en la rehabilitació i tractament del delinqüent ingressat a presó són aquells que tenen en compte no només l’ambient del delinqüent, la seva família, la seva educació escolar i formativa a nivell laboral sinó també l’estudi del seus sentiments i de manera clau la seva cognició, el seu raonament, la seva comprensió i també els seus valors.És per això que els programes eficaços semblen ser aquells que inclouen tècniques adreçades a millorar les habilitats de raonament, la empatia, l’avaluació de les conseqüències de la seva conducta envers els altres i sobre ells mateixos, la reflexió abans de l’acció, les seves habilitats per a la resolució de problemes i també en moltes ocasions les pròpies habilitats socials poc desenvolupades. Els resultats obtinguts analitzen les dades referents a l’impacte de la intervenció envers els interns i de manera específica envers la seva conducta.

The problem of finding a feasible solution to a linear inequality system arises in numerous contexts. In [12] an algorithm, called extended relaxation method, that solves the feasibility problem, has been proposed by the authors. Convergence of the algorithm has been proven. In this paper, we onsider a class of extended relaxation methods depending on a parameter and prove their convergence. Numerical experiments have been provided, as well.

A Neospora caninum 17 kDa protein fraction (p17) has been described as an immunodominant antigen (IDA) under reducing and non-reducing conditions. The aim of the present study was to investigate the diagnostic utility of p17 in cattle. In order to achieve this, p17 was purified by electroelution from whole N. caninum tachyzoite soluble extract and a p17-based Western blot (WB-p17) was developed. The p17 recognition was measured by densitometry and expressed as OD values to check the validity of the WB-p17. A total of 131 sera including sequential samples from naturally- and experimentally-infected calves and breeding cattle were analysed by WB-p17 and compared with IFAT using whole formalin-fixed tachyzoites as a reference test. The results obtained highlight the feasibility of using the N. caninum p17 in a diagnostic test in cattle. Firstly, the assay based on the p-17 antigen discriminated between known positive and negative sera from different cattle populations, breeding cattle and calves. Secondly, the p17 antigen detected fluctuations in the antibody levels and seroconversion in naturally- and experimentally-infected cattle. Significant differences in p-17 antigen recognition were observed between naturally infected aborting and non-aborting cattle, as well as significant antibody fluctuations over time in experimentally infected cattle, which varied between groups. Furthermore, the results obtained with WB-p17 are in accordance with the results obtained with the IFAT, as high agreement values were obtained when all bovine subpopulations were included (kappa = 0.86).

Background: Hand hygiene in the health context is a complex behaviour. There have been rarely given the role of the knowledge and attitudes as predictors of hand hygiene behaviour. The main objective of this work is the description of the development of a questionnaire on hand hygiene and the analysis of their measurement properties. Method: An instrument which was designed and validated a questionnaire. It was held in January 2009. It finally has had 50 items that assess risk behaviour intention before and after contact with the patient, declarative knowledge and attitudes about hand hygiene. It has been applied to 431 students of health sciences at the University of Granada. Results: There were three factor analysis, ultimately obtaining a general convergence value that explains 46.01% of the total variance and high reliability (a=0,843). There is correlation between knowledge and behavior intentions before and after patient contact (p <0.01).In turn, the attitude correlates only with behavioral intention before (p <0.05). The hand hygiene behavior refers to a higher mean after the completion of various health activities before the same (4.26 and 3.96 respectively). Both declarative knowledge and attitudes significantly predict behavioral intention, in particular the conduct before the contact with the patient (R2 = 0.100, standardized Beta 0.256 for knowledge and 0.145 for attitudes). Conclusions: The questionnaire shows high internal consistency. We have obtained a valid tool for assessing risk behavior, knowledge and attitudes about students’ hand hygiene in health sciences. The tool detects deficiencies in basic skills in students.

INTRODUCTION Human host immune response following infection with the new variant of A/H1N1 pandemic influenza virus (nvH1N1) is poorly understood. We utilize here systemic cytokine and antibody levels in evaluating differences in early immune response in both mild and severe patients infected with nvH1N1. METHODS We profiled 29 cytokines and chemokines and evaluated the haemagglutination inhibition activity as quantitative and qualitative measurements of host immune responses in serum obtained during the first five days after symptoms onset, in two cohorts of nvH1N1 infected patients. Severe patients required hospitalization (n = 20), due to respiratory insufficiency (10 of them were admitted to the intensive care unit), while mild patients had exclusively flu-like symptoms (n = 15). A group of healthy donors was included as control (n = 15). Differences in levels of mediators between groups were assessed by using the non parametric U-Mann Whitney test. Association between variables was determined by calculating the Spearman correlation coefficient. Viral load was performed in serum by using real-time PCR targeting the neuraminidase gene. RESULTS Increased levels of innate-immunity mediators (IP-10, MCP-1, MIP-1beta), and the absence of anti-nvH1N1 antibodies, characterized the early response to nvH1N1 infection in both hospitalized and mild patients. High systemic levels of type-II interferon (IFN-gamma) and also of a group of mediators involved in the development of T-helper 17 (IL-8, IL-9, IL-17, IL-6) and T-helper 1 (TNF-alpha, IL-15, IL-12p70) responses were exclusively found in hospitalized patients. IL-15, IL-12p70, IL-6 constituted a hallmark of critical illness in our study. A significant inverse association was found between IL-6, IL-8 and PaO2 in critical patients. CONCLUSIONS While infection with the nvH1N1 induces a typical innate response in both mild and severe patients, severe disease with respiratory involvement is characterized by early secretion of Th17 and Th1 cytokines usually associated with cell mediated immunity but also commonly linked to the pathogenesis of autoimmune/inflammatory diseases. The exact role of Th1 and Th17 mediators in the evolution of nvH1N1 mild and severe disease merits further investigation as to the detrimental or beneficial role these cytokines play in severe illness.

BACKGROUND The re-emergence of tuberculosis (TB) in low-incidence countries and its disproportionate burden on immigrants is a public health concern posing specific social and ethical challenges. This review explores perceptions, knowledge, attitudes and treatment adherence behaviour relating to TB and their social implications as reported in the qualitative literature. METHODS Systematic review in four electronic databases. Findings from thirty selected studies extracted, tabulated, compared and synthesized. FINDINGS TB was attributed to many non-exclusive causes including air-born transmission of bacteria, genetics, malnutrition, excessive work, irresponsible lifestyles, casual contact with infected persons or objects; and exposure to low temperatures, dirt, stress and witchcraft. Perceived as curable but potentially lethal and highly contagious, there was confusion around a condition surrounded by fears. A range of economic, legislative, cultural, social and health system barriers could delay treatment seeking. Fears of deportation and having contacts traced could prevent individuals from seeking medical assistance. Once on treatment, family support and "the personal touch" of health providers emerged as key factors facilitating adherence. The concept of latent infection was difficult to comprehend and while TB screening was often seen as a socially responsible act, it could be perceived as discriminatory. Immigration and the infectiousness of TB mutually reinforced each another exacerbating stigma. This was further aggravated by indirect costs such as losing a job, being evicted by a landlord or not being able to attend school. CONCLUSIONS Understanding immigrants' views of TB and the obstacles that they face when accessing the health system and adhering to a treatment programme-taking into consideration their previous experiences at countries of origin as well as the social, economic and legislative context in which they live at host countries- has an important role and should be considered in the design, evaluation and adaptation of programmes.

INTRODUCTION: Morbid obesity has grown enormously in recent decades, representing a serious public health problem. It is characterized by the accumulation of body fat and the presence of diseases associated with it, which affects the physical, psychological and social level. It has been considered bariatric ciguría as the most effective treatment for weight loss, getting the welfare of the obese person in the above-described drawings. OBJECTIVE: To evaluate the impact on the quality of life of obese people before and after bariatric surgery be tapped using the technique of laparoscopic gastrectomy (GVL) in a follow short, medium and long term. METHOD: The study population are all people with morbid obesity and are candidates for surgery, presenting at Torrecárdenas Bariatric Surgery Hospital (Almería). The design is a descriptive, longitudinal study, prospective. RESULTS: After evaluation of the obese patients a year, two years and five years after surgery, there has been decrease in weight, therefore decrease in BMI and the degree of obesity, improvement or disappearance of comorbidities and increased CV variables. DISCUSSION: The GVL gets reduce excess weight and therefore BMI and the degree of obesity, as well as the number of obesity-associated diseases, thus increasing the CV.

O estudo teve por objetivo avaliar a efetividade de esquemas de monitorização domiciliar sangüíneo e urinário, na obtenção de adequado controle glicêmico, em pacientes com diabetes mellitus do tipo 1, em regime quinzenal de ajuste terapêutico; durante 6 meses de participação em grupos educativos. A amostra foi de 34 pacientes divididos em dois grupos. Os pacientes do grupo A realizaram monitorização domiciliar da glicemia capilar 1 vez ao dia e os do grupo B realizaram monitorização domiciliar da glicosúria 1 vez ao dia, conforme esquemas preconizados. Estes esquemas possibilitaram construção de perfis e de ajustes terapêuticos. Os resultados mostraram que o uso sistemático dos testes domiciliares sangúíneos e urinários da forma prescrita, não proporcionou melhora significante no controle metabólico em nenhum dos dois grupos. Entretanto, favoreceu o processo educativo e possibilitou reflexões sobre a necessidade de intensificação da monitorização glicêmica.
