Grounded in the intersection between gender politics and electoral studies, this dissertation examines the demobilizing effects of violations of personal space (in the form of domestic violence, control over mobility, emotional abuse, and sexual harassment) on the propensity to vote. Using quantitative methods across four survey datasets concerning Lebanon, the United States, Morocco, and Yemen, this research concludes that cross-regionally, familial control over mobility reduces the propensity to vote among women. Conversely, mechanisms of empowerment such as education and employment increase the propensity to vote.

O Plano Tecnológico de Educação (PTE) pretendeu equipar tecnologicamente as escolas públicas de Portugal continental, procurando introduzir, por essa via, alterações e inovação no ensino e na aprendizagem. Neste contexto, importa destacar o papel que os coordenadores do PTE tiveram localmente, já que foram os responsáveis pela sua implementação dentro das escolas. Focámos assim a nossa investigação na figura dos CPTE, de forma a percebermos como o PTE tinha sido implementado e liderado nas escolas. Partimos de um enquadramento do problema, perspetivado em torno de três temas: a construção do Plano Tecnológico de Educação, destacando os seus três eixos e projetos, a problemática da incorporação das tecnologias de informação e comunicação na educação e o papel da liderança em projetos de inovação e mudança. O estudo empírico realizado apoiou-se fundamentalmente em métodos quantitativos, complementado por elementos qualitativos. Foi aplicado um inquérito a uma amostra com representação nacional, de 100 CPTE, de agrupamentos de escolas e escolas não agrupadas de Portugal continental com ensino secundário. Este inquérito permitiu perceber quem foram estes coordenadores ao definirmos o seu perfil relativamente às suas características pessoais e profissionais, às suas competências nas dimensões previstas para a função, bem como à sua liderança, neste caso concreto através da utilização do MLQ, de Bass & Avolio. Permitiu ainda determinar as condições de implementação do PTE e os principais constrangimentos. Os resultados obtidos comprovaram que nem todos os objetivos inicialmente propostos para o PTE foram concluídos ou implementados. No entanto, o balanço a nível tecnológico e de gestão é bastante positivo e menos a nível pedagógico. A liderança desempenhada pela generalidade dos CPTE enquadrou-se no perfil ideal identificado por Avolio & Bass (1995), onde as características de liderança transformacional são as mais manifestadas, complementando-se com algumas de liderança transacional.

For a long time, electronic data analysis has been associated with quantitative methods. However, Computer Assisted Qualitative Data Analysis Software (CAQDAS) are increasingly being developed. Although the CAQDAS has been there for decades, very few qualitative health researchers report using it. This may be due to the difficulties that one has to go through to master the software and the misconceptions that are associated with using CAQDAS. While the issue of mastering CAQDAS has received ample attention, little has been done to address the misconceptions associated with CAQDAS. In this paper, the author reflects on his experience of interacting with one of the popular CAQDAS (NVivo) in order to provide evidence-based implications of using the software. The key message is that unlike statistical software, the main function of CAQDAS is not to analyse data but rather to aid the analysis process, which the researcher must always remain in control of. In other words, researchers must equally know that no software can analyse qualitative data. CAQDAS are basically data management packages, which support the researcher during analysis.

O projeto realizou-se num contexto onde as organizações mantêm os funcionários conectados, motivados, e satisfeitos pessoal e profissionalmente, onde em companhia dos seus líderes, marcham em busca da tão desejada progressão organizacional, maximizando o lucro e minimizando os custos continuamente. Por este motivo, decidiu-se elaborar o projeto, cujo objetivo é avaliar/examinar duas variáveis, a Satisfação Laboral e o Compromisso Organizacional, destacando uma possível associação entre ambas. O universo em análise é a população da empresa angolana no sector da informação, empresa integrada no mercado angolano, cujo objeto de trabalho passa por recolher, tratar e distribuir a informação, nacional e internacionalmente. A mesma teve a amabilidade que disponibilizar os seus 172 colaboradores como amostra para fazer parte deste projeto. Para o estudo foram utilizadas metodologias quantitativas, aplicando-se dois questionários. O primeiro, de Warr, Cook e Wall referente a Satisfação Laboral, e o segundo, de Allen Meyer, refere-se ao Compromisso Organizacional, ambos previamente aprovados/certificados, e utilizados anteriormente com as referidas variáveis. Relativamente aos resultados, observou-se a existência de um impacto significativo entre a variável Satisfação Laboral e a variável Compromisso Organizacional; tento a primeira uma influência positiva sobre a segunda. Os resultados do estudo concluíram que os valores provenientes da correlação de Pearson (Tabela) demonstram o esperado, isto é, existe uma associação positiva com intensidade moderada, fortes e muito fortes (0.60 a 0.97) entre a variável Satisfação laboral Compromisso laboral.

Esta tese pretende contribuir para o conhecimento da migração de treinadores desportivos. Foram realizados quatro estudos para examinar quais os fatores envolvidos na migração de treinadores desportivos. Os dados recolhidos foram tratados através de métodos de análise qualitativa e quantitativa. O primeiro estudo permitiu identificar que estudos sobre a migração no desporto utilizam as dimensões macro e micro de forma independente. As metodologias utilizadas nos estudos, qualitativa ou quantitativa, variam de acordo com a dimensão de definida para o estudo da migração (macro ou micro). Foi também identificado um número bastante reduzido de estudos sobre a migração dos treinadores desportivos. O segundo estudo permitiu identificar que a migração de treinadores desportivos está predominantemente relacionada com mecanismos informais de recrutamento. As motivações dos treinadores para migrar estão maioritariamente relacionadas com três categorias identificadas em estudos anteriores, nomeadamente as categorias: ambicioso, cosmopolita e pioneira. As experiências dos treinadores são focadas principalmente em aspetos desportivos. O terceiro estudo, permitiu identificar um padrão de migração de treinadores desportivos que envolve a sobreposição de fatores económicos, históricos e culturais. De salientar, a importância das relações socias na migração de treinadores para zonas de maior prestígio e para zonas com melhor situação financeira. O quarto estudo, permitiu demonstrar que existe uma polarização no discurso dos meios de comunicação social relativamente aos treinadores estrangeiros. Este tipo de discurso está relacionado, por um lado com o reconhecimento do treinador estrangeiro como essencial no desenvolvimento e sucesso desportivo do país de acolhimento. Por outro lado, o discurso dos meios de comunicação social está relacionado com a estigmatização do treinador estrangeiro como o principal responsável pelo subdesenvolvimento do desporto do país de acolhimento. Os meios de comunicação social do país de acolhimento tendem a estigmatizar os treinadores estrangeiros de mercenários, não comprometidos com o desenvolvimento desportivo nacional. Os resultados globais permitiram propor um quadro conceptual sobre a migração de treinadores desportivos.

A Qualidade é um dos fatores dinâmicos de competitividade e é, incontestavelmente, um dos pilares fundamentais para a construção do sucesso das organizações. O conceito de Qualidade não é de fácil definição, dado que é algo complexo e de difícil consenso. E muitas são as noções de Qualidade existentes na literatura, mas todas elas convergem num sentido único da busca da melhoria contínua e da excelência. Por outro lado, a implementação da Contabilidade de Gestão (designadamente o Custeio Baseado em Atividades - ABC) numa organização, sobretudo numa instituição de ensino, fornece recursos suficientes para a identificação dos melhores indutores de custo. Assim, toma-se inevitável observar as atividades, inquirir os colaboradores internos e externos, desenvolver e aplicar métodos quantitativos que monitorizem os processos e os procedimentos e, especialmente, que exista o empenho da gestão de topo, de modo a que a estratégia e a qualidade organizacional se inter-relacionem. Este trabalho apresenta diversos aspetos referentes à temática dos custos da qualidade (ou da não qualidade), a própria técnica contemporânea ABC e os principais resultados obtidos através da aplicação de listas de verificação e de um inquérito por questionário, junto dos alunos, colaboradores docentes e não docentes, com o objetivo de analisar a situação dos custos da qualidade baseados na contabilidade e avaliar o grau de satisfação/motivação com a qualidade do serviço prestado na sede do Agrupamento de Escolas do concelho de Estremoz. Os resultados do presente estudo evidenciaram alguns benefícios e dificuldades da aplicabilidade da Gestão da Qualidade numa instituição de ensino. A cultura organizacional deste tipo de instituições será um dos aspetos a ter em consideração, de modo a que os princípios da Gestão da Qualidade sejam implementados de forma harmoniosa e que poderá encaminhar essas organizações num verdadeiro percurso de qualidade, numa filosofia de melhoria contínua até à excelência. ABSTRACT: As a crucial factor for competitiveness, quality is undoubtedly one of the foundations on which a successful organization rests. The complexity surrounding the notion of quality makes it hard to reach a consensus about its meaning, and that is why it has so many different definitions. However, all of them have one thing in common - that it involves a continuous search for improvement and excellence. Nowadays, an organization that uses accounting methods to support management (namely the Activity-based Costing method) has the necessary means to identify where the main costs are originating from, particularly if the organization is somehow related to teaching. It is therefore inevitable to study activities, inquire everyone involved in the organization's activities, as well as develop and apply quantitative methods to monitor processes and procedures. Moreover, it is especially important that top management is fully committed to quality in order to reflect it on its strategy. This work focuses on several aspects pertaining costs associated with quality- and lack of quality­ and shows the Activity-based Costing method in particular, as well as the main results gathered from the verification lists and questionnaires made to students, teachers and staff, with the purpose of analyzing - based on accounting - the amount of costs derived from quality, and evaluating the degree of satisfaction and/or motivation as regards the quality of service provided at a group of schools in Portuguese region of Estremoz. The results of this study show that there are some benefits in applying quality management to teaching institutions, but there are also some difficulties. The organizational culture of these institutions is one aspect that should be taken into consideration, so that quality management principles can be implemented harmoniously. This may direct these organizations to the true path of quality, so they can continuously seek improvement and achieve excellence.

O Oficial de Polícia formado pelo Instituto Superior de Ciências Policias e Segurança Interna (ISCPSI) é a figura essencial, enquanto futura chefia superior da Polícia de Segurança Pública (PSP), uma vez que cai sobre a sua responsabilidade levar a cabo que sejam cumpridos os objetivos da Instituição. Como tal, a formação ministrada no ISCPSI revela-se de uma elevada importância, pois permite dotar os seus Oficiais com os conhecimentos e as competências necessárias para o desempenho das suas funções. O presente estudo, baseado em métodos qualitativos e quantitativos, tem como objetivos, por um lado, compreender se existem diferenças ao nível da aquisição de conhecimentos e de competências dos Oficiais de Polícia da PSP que terminaram o Curso de Mestrado Integrado em Ciências Policiais (CMICP) na modalidade de internato em contrapartida com a modalidade de externato e, por outro lado, perceber se os custos associados ao regime de internato justificam a sua manutenção. Realizou-se um estudo de caso que incidiu nos três cursos do CMICP do ISCPSI, onde se realizaram entrevistas aos Diretores e Comandantes do Corpo de Alunos durante a formação dos três cursos e se aplicaram questionários a uma amostra significativa de formandos desses mesmos cursos que frequentaram, uns o regime de internato e outros o regime de externato. Como resultado da investigação verifica-se que na perspetiva dos inquiridos não existem diferenças entre os Oficiais de Polícia que concluíram o curso em regime de internato perante os que o concluíram em regime de externato, no que diz respeito à aquisição de conhecimentos e competências adquiridas. Nesta conformidade, não se justifica a manutenção do regime de internato porque não há perda de qualidade da formação recebida e, traduz-se um ganho significativo com os custos suportados com o regime de internato.

Since the beginning of the National Program for Production and Use of Biodiesel in Brazil, in 2004, different raw materials were evaluated for biodiesel production, trying to combine the agricultural diversity of the country to the desire to reduce production coasts. To determine the chemical composition of biodiesel produced from common vegetables oils, international methods have been used widely in Brazil. However, for analyzing biodiesel samples produced from some alternative raw materials analytical problems have been detected. That was the case of biodiesel from castor oil. Due the need to overcome these problems, new methodologies were developed using different chromatographic columns, standards and quantitative methods. The priority was simplifying the equipment configuration, realizing faster analyses, reducing the costs and facilitating the routine of biodiesel research and production laboratories. For quantifying free glycerin, the ethylene glycol was used in instead of 1,2,4-butanetriol, without loss of quality results. The ethylene glycol is a cheaper and easier standard. For methanol analyses the headspace was not used and the cost of the equipment used was lower. A detailed determination of the esters helped the deeper knowledge of the biodiesel composition. The report of the experiments and conclusions of the research that resulted in the development of alternative methods for quality control of the composition of the biodiesel produced in Brazil, a country with considerable variability of species in agriculture, are the goals of this thesis and are reported in the following pages

Exploring the relationship between early oral reading fluency ability and reading comprehension achievement among an ethnically and racially diverse sample of young learners from low-income families, attending elementary school within a large public school district in southeast Florida is the purpose of this longitudinal study. Although many studies have been conducted to address the relationship between oral reading fluency ability and reading comprehension achievement, most of the existing research failed either to disaggregate the data by demographic subgroups or secure a large enough sample of students to adequately represent the diverse subgroups. The research questions that guided this study were: (a) To what extent does early oral reading fluency ability measured in first, second, or third grade correlate with reading comprehension achievement in third grade? (b) To what extent does the relationship of early oral reading fluency ability and reading comprehension achievement vary by demographic subgroup membership (i.e., gender, race/ethnicity, socioeconomic status) among a diverse sample of students? A predictive research design using archived secondary data was employed in this nonexperimental quantitative methods study of 1,663 third grade students who attended a cohort of 25 Reading First funded schools. The data analyzed derived from the Dynamic Indicators of Basic Early Literacy Skills Oral Reading Fluency (DIBELS ORF) measure administered in first, second, and third grades and the Florida Comprehensive Assessment Test of the Sunshine State Standards (FCAT-SSS) Reading administered in third grade. Linear regression analyses between each of the oral reading fluency and reading comprehension measures produced significant positive correlations. Hierarchical regression analyses supported the predictive potential of all three oral reading fluency ability measures toward reading comprehension achievement, with the first grade oral reading fluency ability measure explaining the most significant variance in third grade reading comprehension achievement. Male students produced significant overall differences in variance when compared to female students as did the Other student subgroup (i.e., Asian, Multiracial, and Native American) when compared to Black, White, and Hispanic students. No significant differences in variance were produced between students from low and moderate socioeconomic families. These findings are vital toward adding to the literature of diverse young learners.

The purpose of the study was to compare the English III success of students whose home language is Haitian Creole (SWHLIHC) with that of the more visible African American high school students in the Miami Dade County Public Schools System, in an effort to offer insight that might assist educators in facilitating the educational success of SWHLIHC in American Literature class. The study was guided by two important theories on how students interact with and learn from literature. They are Reader Response Theory which advocates giving students the opportunity to become involved in the literature experience (Rosenblatt, 1995), and Critical Literacy, a theory developed by Paolo Freire and Henry Giroux, which espouses a critical approach to analysis of society that enables people to analyze social problems through lenses that would reveal social inequities and assist in transforming society into a more equitable entity. Data for the study: 10th grade reading FCAT scores, English III/American Literature grades, and Promotion to English IV records for the school year 2010-2011 were retrieved from the records division of the Miami Dade County Public Schools System. The study used a quantitative methods approach, the central feature of which was an ex post facto design with hypotheses (Newman, Newman, Brown, & McNeely, 2006). The ex post facto design with hypotheses was chosen because the researcher postulated hypotheses about the relationships that might exist between the performances of SWHLIHC and those of African American students on the three above mentioned variables. This type of design supported the researcher’s purpose of comparing these performances. One way analysis of variance (ANOVA), two way ANOVAs, and chi square tests were used to examine the two groups’ performances on the 10th grade reading FCAT, their English III grades, and their promotion to English IV. The study findings show that there was a significant difference in the performance of SWHLIHC and African American high school students on all three independent variables. SWHLIHC performed significantly higher on English III success and promotion to English IV. African American high school students performed significantly higher on the reading FCAT.

The overall aim was to investigate the quality of palliative care from the patient perspective, to adapt and psychometrically evaluate the Quality from Patients’ Perspective instrument specific to palliative care (QPP-PC) and investigate the relationship between the combination of person- and organization-related conditions and patients’ perceptions of care quality. Methods: In the systematic literature review (I), 23 studies from 6 databases and reference lists in 2014 were synthesized by integrative thematic analysis. The quantitative studies (II–IV) had cross-sectional designs including 191 patients (73% RR) from hospice inpatient care, hospice day care, palliative units in nursing homes and home care in 2013–2014. A modified version of QPP was used. Additionally, person- and organization-related conditions were assessed. Psychometric evaluation, descriptive and inferential statistics were used. Main findings: Patients’ preferences for palliative care included living a meaningful life and responsive healthcare personnel, care environment and organization of care (I). The QPP-PC was developed, comprising 12 factors (49 items), 3 single items and 4 dimensions: medical–technical competence, physical–technical conditions, identity–oriented approach, and socio-cultural atmosphere (II). QPP-PC measured patients’ perceived reality (PR) and subjective importance (SI) of care quality. PR differed across settings, but SI did not (III). All settings exhibited areas of strength and for improvement (II, III). Person-related conditions seemed to be related to SI, and person- and organization-related conditions to PR, explaining 18–30 and 22-29% respectively of the variance (IV). Conclusions: The patient perspective of care quality (SI and PR) should be integrated into daily care and improvement initiatives in palliative care. The QPP-PC can measure patients’ perceptions of care quality. Registered nurses and other healthcare personnel need awareness of person- and organization-related conditions to provide high-quality person-centred care.

The aim of this thesis was to describe and explore how the partner relationship of patient–partner dyads isaffected following cardiac disease and, in particular, atrial fibrillation (AF) in one of the spouses. The thesis is based on four individual studies with different designs: descriptive (I), explorative (II, IV), and cross-sectional (III). Applied methods comprised a systematic review (I) and qualitative (II, IV) and quantitative methods (III). Participants in the studies were couples in which one of the spouses was afflicted with AF. Coherent with a systemic perspective, the research focused on the dyad as the unit of analysis. To identify and describe the current research position and knowledge base, the data for the systematic review were analyzed using an integrative approach. To explore couples’ main concern, interview data (n=12 couples) in study II were analyzed using classical grounded theory. Associations between patients and partners (n=91 couples) where analyzed through the Actor–Partner Interdependence Model using structural equation modelling (III). To explore couples’ illness beliefs, interview data (n=9 couples) in study IV were analyzed using Gadamerian hermeneutics. Study I revealed five themes of how the partner relationship is affected following cardiac disease: overprotection, communication deficiency, sexual concerns, changes in domestic roles, and adjustment to illness. Study II showed that couples living with AF experienced uncertainty as the common main concern, rooted in causation of AF and apprehension about AF episodes. The theory of Managing Uncertainty revealed the strategies of explicit sharing (mutual collaboration and finding resemblance) and implicit sharing (keeping distance and tacit understanding). Patients and spouses showed significant differences in terms of self-reported physical and mental health where patients rated themselves lower than spouses did (III). Several actor effects were identified, suggesting that emotional distress affects and is associated with perceived health. Patient partner effects and spouse partner effects were observed for vitality, indicating that higher levels of symptoms of depression in patients and spouses were associated with lower vitality in their partners. In study IV, couples’ core and secondary illness beliefs were revealed. From the core illness belief that “the heart is a representation of life,” two secondary illness beliefs were derived: AF is a threat to life, and AF can and must be explained. From the core illness belief that “change is an integral part of life,” two secondary illness beliefs were derived: AF is a disruption in our lives, and AF will not interfere with our lives. Finally, from the core illness belief that “adaptation is fundamental in life,” two secondary illness beliefs were derived: AF entails adjustment in daily life, and AF entails confidence in and adherence to professional care. In conclusion, the thesis result suggests that illness, in terms of cardiac disease and AF, affected and influenced the couple on aspects such as making sense of AF, responding to AF, and mutually incorporating and dealing with AF in their daily lives. In the light of this, the thesis results suggest that clinicians working with persons with AF and their partners should employ a systemic view with consideration of couple’s reciprocity and interdependence, but also have knowledge regarding AF, in terms of pathophysiology, the nature of AF (i.e., cause, consequences, and trajectory), and treatments. A possible approach to achieve this is a clinical utilization of an FSN based framework, such as the FamHC. Even if a formalized FSN framework is not utilized, partners should not be neglected but, rather, be considered a resource and be a part of clinical caring activities. This could be met by inviting partners to take part in rounds, treatment decisions, discharge calls or follow-up visits or other clinical caring activities. Likewise, interventional studies should include the couple as a unit of analysis as well as the target of interventions.

The physical environment can influence older people’s health and well-being, and is often mentioned as being an important factor for person-centred care. Due to high levels of frail health, many older people spend a majority of their time within care facilities and depend on the physical environment for support in their daily life. However, the quality of the physical environment is rarely evaluated, and knowledge is sparse in terms of how well the environment meets the needs of older people. This is partly due to the lack of valid and reliable instruments that could provide important information on environmental quality. Aim: The aim of this thesis was to study the quality of the physical environment in Swedish care facilities for older people, and how it relates to residents’ activities and well-being. Methods: The thesis comprises four papers where both qualitative and quantitative methods were used. Study I involved the translation and adaptation of the Sheffield Care Environment Assessment Matrix (SCEAM) into a Swedish version (S-SCEAM). Several methods were used including forward and backward translation, test of validity via expert consultation and reliability tests. In Study II, S-SCEAM was used to assess the quality of the environment, and descriptive data were collected from 20 purposively sampled residential care facilities (RCFs). Study III was a comparative case study conducted at two RCFs using observations, interviews and S-SCEAM to examine how the physical environment relates to older people’s activities and interactions. In study IV, multilevel modeling was used to determine the association between the quality of the physical environment and the psychological and social well-being of older people living in RCFs. The data in the thesis were analysed using qualitative content analysis, and descriptive, bivariate and multilevel statistics. Results: A specific result was the production of the Swedish version of SCEAM. The instrument contains 210 items structured into eight domains reflecting the needs of older people. When using S-SCEAM, the results showed a substantial variation in the quality of the physical environment between and within RCFs. In general, private apartments and dining areas had high quality, whereas overall building layout and outdoor areas had lower quality. Also, older people’s safety was supported in the majority of facilities, whereas cognitive support and privacy had lower quality. Further, the results showed that environmental quality in terms of cognitive support was associated with residents’ social well-being. Specific environmental features, such as building design and space size, were also noted, through observation, as influencing residents’ activities, and several barriers were found that seemed to restrict residents’ full use of the environment. Conclusions: This thesis contributes to the growing evidence-based design field. The S-SCEAM can be used in future research on the association between the environment and people’s health and well-being. The instrument could also serve as a guide in the planning and design process of new RCFs.
