Social exclusion is a problem in today’s society that we feel public libraries can help resolve since they are based on the idea of equality and openness. The purpose of this essay is to examine how public librarians think and reason about the concept “integration” as well as what role public libraries can play in immigrants’ integration process. With Jose Alberto Diaz’ theory on the integration process, and Marianne Andersson and Dorte Skot-Hansen’s model for analysis of the local library profile as theoretical framework, we analyzed the responses from two qualitative interviews in small groups of 2-3 librarians from two different public libraries. The result of this study shows that some public librarians cannot give an accurate definition of the word integration; instead they define integration as mutual respect for cultural differences. Only two librarians included in their definition that integration means to become participants in society. Despite this lack of a comprehensive understanding of the concept the librarians have a positive attitude towards the public libraries’ ability to support the integration process through book collection and program activities. The librarians think that public libraries mostly support the integration by: 1) increasing the understanding between different cultures and thereby decreasing prejudice and fear in the society (personal integration), 2) help immigrants develop a social network with the majority culture (social integration), and 3) help immigrants with language development(communicative integration). This is done mostly by focusing on the public libraries’ role of knowledge and education as well as their social role.

Assim, a comunicação limitada - aqui entendida como baixo nível de representatividade -, leva a resultados limitados no aprofundamento da democracia na região. Isso afeta tanto a própria estrutura decisória do bloco, quanto a possibilidade da criação de uma sociedade ―regional‖ mais avançada em seus valores de respeito à liberdade e dignidade humana, seja por parte dos cidadãos ou por parte dos Estados. Diante disso, supomos que existe um descolamento entre exercício democrático e o processo decisório no Mercosul, que merece ser mais detidamente explorado. / If we take as reference a view of politics as a process of consensus building through dialogue, the current stage of Mercosur shows that there is no maturation of decision-making process nor the creation of a new regional public space. Thus, the limited communication - understood here as a low level representation - leads to limited results in democracy development in the region. This situation affects both their own decision-making structure of the block, and the possible creation of a regional society more advanced in their values of respect for human dignity and freedom, either by individuals or by states. Therefore, we assume that there is a detachment between democratic exercise and decision-making process in Mercosur, which deserves to be explored more closely.

In connection to an existing research project, Micro-migration and Integration with relevance for Uddevalla, this study aims to analyse and compare the subjective understandings of Somali women’s experiences in the integration process in the Swedish society. Integration is a multifaceted and ongoing process in which the self-understandings of this notion is bound to change over time in relation to socio-economic and cultural contexts. In light of this, the thesis employs a comparative case study that is based on data collected through focus group discussions with newly arrived women and women who have stayed in Sweden for a longer time. The analytical framework utilizes acculturation theory to study what traces of integration, assimilation, separation and marginalization can be identified in the selfunderstandings and how they develop over time. Some of the conclusions from the study by the interviewees notify language being crucial. Both groups understand that Swedish constitutes a step in the overall process for establishment and the newly arrived women showed an awareness about it being the ultimate factor that can speed up their own integration process. The findings of the research include that there is a deviation of the understandings between the groups when it comes to housing and identity. The group of newly arrived women with the exception of one participant, indicated a clear separation in regard to both aspects above whereas the women who have lived in Sweden for 9-10 years showed clear traces of integration. Hence, in the beginning of the integration process a person might have a theoretical understanding that indicates separation but experience a discursive shift towards the lens of integration.

Corporate acquisitions have long been seen as contributing to financial success. Other motives for acquisitions are the longing for power, more competitive advantages and growth. However, the majority of business acquisitions fail in practice, and many argue that the most difficult process in an acquisition is the integration process. A company that has recently been acquired is a Swedish manufacturing company, which has just been acquired by its American competitor. They are in the midst of integration where problems often arise. Integration occurs on an operational and a cultural front, which can be problematic. It is therefore interesting to study how the management control and organizational culture are affected in the acquired company, and whether this supports or prevents the integration process and thus affects the success of the acquisition. The purpose of the study is to describe and explain how the acquired company's management control and culture are affected by acquisitions. The study further intends to explain whether the changes support or hinder the integration process. The study will contribute to an increased understanding of how management control and culture can be managed in order for a business acquisition to be successful. To fulfill the purpose, a qualitative research method was used and an explanatory case study was applied. Theory was collected from books, scientific articles, newspaper articles and internal material. Empiri was collected through semi-structured interviews, which were then transcribed, which were sent to respondents for review. The material was then analyzed by a thematic analysis. In order to ensure that the study was of good quality, various quality criterias and ethical considerations were also taken into account. The acquisition of the company has been shown to influence both the management control and the culture of the acquired company. Management control is affected by the acquired company becoming more centralized, detail-controlled, a changed focus in strategies, tougher rules and increased communication and performance measurement, which are factors that hinder and/or support integration. The culture of the acquired company is influenced by elements of the national culture that the buyer has, such as a changed way of working, cooperation spirit and developed into a more international company, which supports and/or hinders integration. Improvement suggestions on how manangement control and culture could be managed to promote integration are through; focus more on human aspects, leadership, introduce reward systems, gather information on both company cultures, pay attention to employees' emotions and that the changes introduced are similar to the original culture of the acquired company.

Yes / The family environment plays a crucial role in child physical activity (PA). Wearable activity trackers (wearables) show potential for increasing children's PA; however, few studies have explored families' acceptance of wearables. This study investigated the acceptability of using wearables in a family setting, aligning experiences with components of the Technology Acceptance Model and Theoretical Domains Framework. Twenty-four families, with children aged 5-9 years, took part in a 5-week study, where all members were provided with a Fitbit Alta HR for 4 weeks. Acceptability was measured using weekly surveys and pre-post-questionnaires. Nineteen families participated in a focus group. Quantitative and qualitative data were integrated using the Pillar Integration Process technique. Pillars reflected (1) external variables impacting wearable use and PA and (2) wearable use, (3) ease of use, (4) usefulness for increasing PA and other health outcomes, (5) attitudes, and (6) intention to use a wearable, including future intervention suggestions. Families found the Fitbit easy to use and acceptable, but use varied, and perceived impact on PA were mixed, with external variables contributing towards this. This study provides insights into how wearables may be integrated into family-based PA interventions and highlights barriers and facilitators of family wearable use. / This study is funded as part of a Ph.D. studentship by the Born in Bradford study.

Les procédés d’oxydation chimique sont utilisés pour traiter des effluents contenant des composés organiques non biodégradables. Or, la présence de sels diminue l’efficacité de ce traitement. Dans ce travail, nous étudions un procédé couplé, comprenant une étape de déminéralisation par électrodialyse associée à une étape de photo oxydation (photo-Fenton). Une eau synthétique, contenant du NaCl et du phénol, est utilisée comme modèle. Chaque opération est étudiée en couplant des outils expérimentaux et théoriques. Concernant l’électrodialyse, l’influence des variables opératoires, comme la composition initiale de l’eau à traiter et la densité de courant, sur le taux de déminéralisation et le rendement en phénol, est évaluée. Différents types d’expériences sont réalisées pour dissocier les contributions des divers phénomènes au transfert d’eau, de sel et de phénol. Dans des conditions standard, outre la diffusion, une contribution additionnelle au transfert de phénol, directement proportionnelle au transfert d’eau et donc à la migration des sels, est mise en évidence. Un modèle phénoménologique est proposé pour relier les flux aux forces agissantes et les paramètres caractéristiques sont déterminés en ajustant les résultats expérimentaux avec ceux du modèle. Le procédé d’oxydation photo chimique (Fenton) est ensuite étudié suivant une approche similaire. La sensibilité du procédé, caractérisé par une vitesse de dégradation, aux variables d’entrée est évaluée. En particulier, on montre une influence de la présence de sels. Eu égard à la complexité du système réactionnel, un modèle de type réseau de neurones est choisi pour modéliser la relation entre l’efficacité de l’oxydation aux conditions opératoires. Dans un dernier temps, un modèle hybride est proposé en intégrant les modèles développés pour les étapes d’électrodialyse et d’oxydation. Ce modèle est testé en discutant différentes configurations vis-à-vis de considérations énergétiques. Il sera utilisé pour étudier les configurations les plus adaptées vis-à-vis d’autres critères, comme la qualité de l’eau traitée par exemple. / Chemical oxidation processes can be used to treat industrial wastewater containing non-biodegradable organic compounds. However, the presence of dissolved salts may inhibit or retard the treatment process. In this work, a coupled process is studied including a desalination step by electrodialysis (ED) associated with an advanced oxidation process (photo-Fenton) with a synthetic wastewater containing NaCl and phenol. The experimental study concerning ED was carried out using a pilot plant. The influence of process variables, like the initial water composition and the electrical current intensity, on the demineralization factor was investigated. Experiments were also performed without electrical current application, in order to determine the unfavorable phenol transfer through the membranes due to diffusion. The phenol and salt concentration variations in the ED compartments were measured over time, using dedicated procedures and an experimental design to determine the global characteristic parameters. A phenomenological approach was used to relate the phenol, salt and water fluxes with the driving force (concentration and electric potential gradients). Under normal ED conditions, two contributions were pointed out for the phenol transport, i.e. Diffusion and convection, this latter coming from the water flux due to electroosmosis related to the migration of salts. The fitting of the parameters of the transport equations resulted in good agreement with the experimental results over the range of conditions investigated. Photo- enton oxidation process was studied in a laboratory batch reactor. As expected, the results confirm the negative effect of the salt concentration on the phenol removal efficiency by oxidation. This effect was not found to be linear concerning salt concentration and degradation rate. Due to the complexity of these reaction systems, a model based on artificial neural networks has been developed to fit the experimental data. This model describes the evolution of the pollutant concentration i.e. phenol, by means of a reaction rate, during irradiation time under various operating conditions.

Os processos oxidativos podem ser utilizados no tratamento de efluentes contendo compostos orgânicos não-biodegradáveis. No entanto, a presença de sais dissolvidos pode inibir ou retardar o processo. Neste estudo, a dessalinização de efluentes por eletrodiálise (ED) associada a um processo de oxidação avançada (foto-Fenton) foi aplicada a uma solução aquosa contendo NaCl e fenol. O processo de ED foi avaliado em escala piloto. Um estudo experimental foi realizado no qual a influência das variáveis de processo na perda de fenol e remoção do cloreto de sódio foi investigada. Experimentos também foram realizados sem corrente elétrica para determinar a transferência de fenol devido à difusão. As variações de concentração de fenol e sal nos compartimentos do sistema de ED foram medidas com o tempo utilizando-se procedimentos pertinentes e um planejamento experimental para determinar os parâmetros característicos globais. Uma abordagem fenomenológica foi utilizada para relacionar os fluxos de fenol, sal e água com as forças motrizes (concentração e gradiente de potencial elétrico). Nas condições de ED estudadas duas contribuições ao transporte do fenol se destacaram: difusão e convecção, sendo a última devido ao fluxo de água relacionado com eletroosmose pela migração do sal. Os parâmetros estimados das equações de transporte possuem bom ajuste com os resultados experimentais na faixa de condições investigadas. O processo foto-Fenton foi estudado em um reator de batelada em escala de laboratório. Os resultados confirmam o efeito negativo da concentração de sal na eficiência de remoção de fenol por oxidação.

Devido à complexidade das reações do sistema, um modelo baseado em redes neurais artificiais foi desenvolvido para ajustar os dados experimentais no equacionamento da taxa de reação em função das variáveis de entrada. O modelo descreve a evolução da concentração do poluente, fenol, pela taxa de reação, durante o tempo de irradiação para diferentes condições operacionais. O modelo matemático das etapas de ED e de foto-oxidação foi utilizado para avaliar a sensibilidade do processo em relação às variáveis consideradas.

For many firms, particularly those operating in high technology and competitive markets, knowledge is cited as the most important strategic asset to the firm, which significantly drives its survival and success. Knowledge management (KM) impacts the firm's ability to develop process features that reduce manufacturing costs, product designs with the features and functionality to match consumer demand, and time to market. Unfortunately, many firms lack an understanding of how to develop and exploit knowledge capabilities for success. In this thesis I develop a rich and multifaceted understanding of how KM strategies lead to successful outcomes for a firm. The thesis comprises three essays, described below. The first essay (Chapter 2) examines how volume-based learning influences the relationship between a buyer and supplier in a two-period Stackelberg game. Three types of knowledge management practices are considered. First, in contrast to the literature, I recognize that knowledge accumulated from current in-house production contributes to the buyer's future product and process development efforts. Second, I allow the supplier to invest in integration process improvement (a form of knowledge development) to reduce the buyer's integration cost. Therefore, the supplier has two mechanisms to impact the buyer's demand: price and process improvement. Lastly, both the buyer and supplier benefit from volume-based learning that reduces their respective production costs. I provide conditions under which the buyer partially outsources component demand as opposed to fully outsourcing or fully producing in-house. In addition, I identify conditions for which the supplier's price and investment in integration process improvement can serve either as substitutes or complements. In the second essay (Chapter 3), I consider knowledge development (KD) strategies in a new product development (NPD) project with three stages of activities conducted concurrently: prototyping, pilot line testing, and production ramp-up. I capture the link between successive stages of engineering activities by recognizing that knowledge accumulated in one stage and transferred to another stage improves the efficiency of knowledge development in the recipient stage. A Base Model and two extensions are introduced that differ in the manner in which knowledge transfer (KT) occurs. I find that the NPD manager pursues different dynamic strategies for KD in each stage of the project. In addition, I explore how the effectiveness of KD and the returns to KT impact the optimal strategies adopted in each stage. In the third essay (Chapter 4), I introduce a dynamic model to explore the impact of KT on a manager?s pursuit of an existing product improvement project and a new product development project. These two projects consume costly knowledge development resources. A key feature of the model is the characterization of the knowledge transfer process from the new product development project to the existing product improvement project. As a result of KT, the ability of the existing product improvement project to generate new knowledge is enhanced. However, the ability of the new product to generate expected net revenue when it is released to the marketplace is reduced due to the loss of proprietary knowledge. I obtain dynamic optimal strategies of KD in both projects and the optimal strategy of KT from the new product development project to the existing product improvement project.
