A pesar de la importancia de la exclusión social, no existe consenso sobre como se debe definir este fenómeno, ni de cómo debe medirse. El objetivo de esta tesis es afrontar estos problemas, definiendo una medida adecuada de exclusión social, para analizar posteriormente su dinámica. He desarrollado un enfoque de medición, de acuerdo con la definición operativa de exclusión social (considerando también estudios anteriores), para establecer si la exclusión social es un fenómeno parcialmente transitorio, así como para analizar las eventuales trayectorias de dependencia que la exclusión puede generar. Mi análisis es un nuevo enfoque para estudiar la exclusión social, y ofrece nueva evidencia empírica sobre la dinámica de la exclusión social en España desde el 1994 hasta el 2000 (usando los datos del panel europeo).He definido exclusión social como el proceso multi-dimensional que lleva a un estado individual de exclusión respecto al resto de la sociedad donde el individuo vive. La exclusión social en un instante del tiempo se define como la imposibilidad de conseguir algunos importantes "functionings". La elección de una medida adecuada de exclusión social no es nada fácil. Propongo usar un caso especial de la generalization multidimensional del índice de Foster-Green-Thorbecke. La motivación principal es que este índice tiene buenas propiedades axiomáticas (Bourguignon and Chakravarty, 2003) y es capaz de operazionalizar el enfoque de la capacidad de Sen. Remarcar que este índice es también adecuado para capturar la multidimensionalidad de la exclusión social y da una idea sobre la intensidad de la exclusión.He estudiado en profundidad la movilidad de la exclusión social siguiendo un enfoque relativo y utilizando las matrices de transición (análisis "two-stages"). Los principales motivos para usar las matrices de transición son los siguientes: primero, el análisis "two-stages" nos da una imagen sencilla de los movimientos de los individuos entre las clases especificas de exclusión social y, segundo, este análisis es robusto frente a la contaminación de los datos. Este tipo de análisis muestra que la exclusión social fue parcialmente un fenómeno transitorio. Me he centrado también en las causas del proceso de exclusión social, y encontré que un individuo que experimenta exclusión hoy, tiene mayor probabilidad de experimentar exclusión mañana, debido a la heterogeneidad observable y no-observable entre individuos, así como a la existencia de un verdadero estado de dependencia. El análisis ha consistido en estimar un modelo no-lineal de datos de panel. He utilizado un enfoque "random effects", y he elegido la solución propuesta en Wooldridge (2002) para solucionar el problema de las condiciones iniciales. Este enfoque muestra la importancia de la existencia de un verdadero estado de dependencia, así como de heterogeneidad entre individuos tanto observable como no-observable. / Despite its importance, there is remarkably little consensus among scientists on the definition of "social exclusion" and, therefore, on the best way to measure it. My aim in this thesis has been to address key problems regarding how to identify an adequate measure of social exclusion and how to analyse social exclusion dynamics. I then proceeded to develop an approach to measurement which was in accord with the working definition of social exclusion (considering also the previous literature), and I used it to establish if social exclusion was partially transitory, and to study eventual dependence paths that exclusion might generate. Note that my analysis proposes new approaches to study social exclusion and offers fresh empirical evidence on social exclusion dynamics in Spain from 1994 to 2000 (using ECHP data).I define social exclusion as a multidimensional dynamic process leading to a state of individual exclusion relative to the rest of the society where the individual lives in. Social exclusion at a point in time is defined as the impossibility to achieve some relevant functionings. The choice of an index able to adequately measure exclusion is not easy. I have proposed to use a special case of the multidimensional generalization of the Foster-Green-Thorbecke index. The main reason has been that this index fulfils a set of axiomatic properties (Bourguignon and Chakravarty, 2003) and it is able to operazionalize Sen's capability approach. Note that this index is also adequate to capture the multidimensionality of social exclusion and gives us information about the intensity of exclusion.I have performed a detailed analysis of social exclusion mobility following the relative approach and using transition matrices (two-stage analysis). The main advantages of using transition matrices are the following: first, two-stage analysis provides a simple picture of the "movement" of the individuals among the specific social exclusion classes and, second, it is shown to be robust to data contamination. This kind of analysis have shown that social exclusion was partially a transitory phenomenon. I have also focused on the causes leading to social exclusion process. I did find that an individual experiencing exclusion today was more likely to experience exclusion tomorrow due to both observed and unobserved individual heterogeneity and true state of dependence. The analysis has been done estimating a dynamic non-linear panel data model. I have used the random effects approach, and I have applied the solution proposed by Wooldridge (2002) to solve the initial condition problems. This approach have shown evidence of the importance of both true state dependence and observed/unobserved heterogeneity.

In Virginia Woolf’s A Room of One’s Own the narrator clearly expresses her rage and resentment exposing the absence and exclusion of women through history and she also focuses on the unfair position of women in her contemporary society. The narrator encourages women to emancipate themselves and to be aware of the idiosyncratic nature of society that restricts them to the private sphere. The aim of this paper is to offer a different interpretation of A Room of One’s Own and demonstrate how Woolf excludes contemporary working-class women from partaking in her feminist message. In order to demonstrate the exclusion of working-class women three major perspectives have been integrated throughout the text: readings of A Room of One’s Own, a historical aspect including classism, and the significance of Woolf’s biographical background. My analysis highlights Woolf’s unintentional class bias, her ladylike manner, and the centrality of financial independence in A Room of One’s Own and displays how these features entail the exclusion of working-class women. The conclusion demonstrates that the amalgamation of the three perspectives mentioned above provides a nuanced and critical reading of A Room of One’s Own.

The aim of this study was to explore refugees experiences of an introduction program in a small Swedish municipality. The study was based on semi-structured interviews with six refugees and was conducted to explore how the introduction program contributed or has not contributed to feelings of being integrated. Our informants have got different backgrounds but have all been forced to flee their home country to Sweden. The interview data was interpreted through earlier research, theories about social exclusion and concepts which were relevant for our study. Our study showed that the informants felt kindly received in the small municipality. The informants emphasizes the small village where segregation among Swedes and refugees was less of a problem. The different parts of the introduction program was of importance, according to the informants, but they also stressed that the introduction program, in itself, isn’t enough to become integrated in the Swedish country. The informants explained that the individual person must take responsibility for its own integration beside taking part of the introduction program. The study showed that the most difficult problems occur when the introduction program is ended and the time to find “established” employment has come.

Previous reports have shown that some bacteria utilize a dissimilatory nitrate reductase enzyme (NR) in anaerobic environments. This enzyme reduces nitrate to nitrite and also has been shown to co-metabolize chlorate to cytotoxic chlorite. A commercially available competitive exclusion (CE) product was evaluated for its nitrate reductase activity and therefore its experimental chlorate product (ECP) sensitivity. Of the 29 constituent bacteria of the CE culture, 11 had slight utilization of NR, 3 had moderate utilization of NR; the remaining were NR negative (with slight and moderate utilization: >0.1 to < 1.0 mM and > 1.0 mM nitrate utilized within 6 h, respectively). In vivo studies utilizing CE and ECP showed significant reductions in Salmonella. Although some of the bacteria were affected by ECP, the combined effect of the CE culture and ECP were effective in reducing Salmonella. Clostridium perfringens (CP) is a pathogen in the commercial poultry industry, which is the etiologic agent of necrotic enteritis (NE). Day-of-hatch broilers were fed a wheat diet and assigned to the following groups: control, commercial coccidia vaccine, commercial bursal disease vaccine, or the combination of the two, and challenged with CP in order to develop a disease model. Broilers in each treatment group had significant increases (P≤ 0.05) in lesion scores, mortality, and CP incidence. As pressure mounts for discontinuing the use of antibiotics in the agriculture industry, it is important to develop new strategies to combat these costly enteric pathogens. In vitro investigations evaluated a mixed gut culture with CP and the ECP at 5 mM or a 10 mM concentrations, over time. By 3 h there was a reduction (P≤ 0.05) in the 5 mM ECP and 10 mM ECP treatment groups. In vivo studies showed significant reductions in the incidence of CP and populations of intrinsic E. coli in all of the chickens provided ECP in the drinking water. Birds administered ECP in the feed showed significant reductions in lesion scores, incidence of CP and also had reduced E. coli log10 values. These results show that an ECP could provide the industry with a new management tool for controlling NE.

The disproportionate exposure to exclusionary discipline for students with disabilities is an acknowledged phenomenon. However, a theoretical understanding for this phenomenon is unknown. Recent claims have been made that the disproportionate use of exclusionary discipline for students with disabilities results from a long-standing historical pattern of discrimination. The use of exclusionary discipline for students with disabilities results in the denial of opportunities and services at a more frequent rate than their peers without disabilities. This denial would indicate the possibility of prejudice, a construct understood to arise from the existence of a perception of threat by the ingroup in an intergroup relationship. The purpose of this study was to (a) determine if school administrators hold perceptions of threat from students with disabilities and (b) if a relationship exists between identified threats and disciplinary decisions. A survey measured threat perception, administrators' attitude toward students with disabilities, and administrators' disciplinary action preference in instances involving students with disabilities. It was hypothesized: H1. Perceived realistic threats will have a direct effect on administrator disciplinary decisions. H2. Perceived threats (both realistic and symbolic) will have a direct effect on administrator attitudes towards students with disabilities. H3. Perceived threats (both realistic and symbolic) will have an indirect effect through attitude on administrator disciplinary decisions. Confirmatory factor analysis revealed an acceptable model fit of the four latent variables of realistic and symbolic threat, educational administrator attitude toward students with disabilities, and educational administrator discipline decisions for students with disabilities. An acceptable fit was found for the originally hypothesized structural model, and no improved alternative models were identified. Realistic threat was found to have a significant relationship to educational administrators' disciplinary decisions for students with disabilities. No significant paths were identified for symbolic threat or attitude. / text
