Why are some companies more successful than others? An exploration into organizational culture and dynamic capabilities

Why are some companies more successful than others? This thesis approaches the question by enlisting theoretical frameworks that explain the performance with internal factors, deriving from the resource-based view, namely the dynamic capabilities approach. To deepen the understanding of the drivers and barriers towards developing these higher order routines aiming at improving the operational level routines, this thesis explores the organisational culture and identity research for the microfoundational antecedents that might shed light on the formation of the dynamic capabilities. The dynamic capabilities framework in this thesis strives to take the theoretical concept closer to practical applicability. This is achieved through creation of a dynamic capabilities matrix, consisting of four dimensions often encountered in dynamic capabilities literature. The quadrants are formed along internal-external and resources-abilities axes, and consist of Sensing, Learning, Reconfiguration and Partnering facets. A key element of this thesis is the reality continuum, which illustrates the different levels of reality inherent in any entity of human individuals. The theoretical framework constructed in the thesis suggests a link between the collective but constructivist understanding of the organisation and both the operational and higher level routines, evident in the more positivist realm. The findings from three different case organisations suggest that the constructivist assumptions inherent to an organisation function as a generative base for both drivers and barriers towards developing dynamic capabilities. From each organisation one core assumption is scrutinized to identify its connections to the four dimensions of the dynamic capabilities. These connections take the form of drivers or barriers – or have the possibility to develop into one or the other. The main contribution of this thesis is to show that one key for an organisation to perform well in a turbulent setting, is to understand the different levels of realities inherent in any group of people. Recognising the intangible levels gives an advantage in the tangible ones.

Role of Platinum Deposited on TiO2 in Photocatalytic Methanol Oxidation and Dehydrogenation Reactions

Titania modified nanoparticles have been prepared by the photodeposition method employing platinum particles on the commercially available titanium dioxide (Hombikat UV 100). The properties of the prepared photocatalysts were investigated by means of the Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), atomic force microscopy (AFM), and UV-visible diffuse spectrophotometry (UV-Vis). XRD was employed to determine the crystallographic phase and particle size of both bare and platinised titanium dioxide. The results indicated that the particle size was decreased with the increasing of platinum loading. AFM analysis showed that one particle consists of about 9 to 11 crystals. UV-vis absorbance analysis showed that the absorption edge shifted to longer wavelength for 0.5% Pt loading compared with bare titanium dioxide. The photocatalytic activity of pure and Pt-loaded TiO2 was investigated employing the photocatalytic oxidation and dehydrogenation of methanol. The results of the photocatalytic activity indicate that the platinized titanium dioxide samples are always more active than the corresponding bare TiO2 for both methanol oxidation and dehydrogenation processes. The loading with various platinum amounts resulted in a significant improvement of the photocatalytic activity of TiO2. This beneficial effect was attributed to an increased separation of the photogenerated electron-hole charge carriers.

Which way out of poverty? the human capital versus human capabilities approaches

La pobreza es un problema mundial que afecta a personas de diferentes maneras. El propósito de este artículo es explorar dos teorías principales que abordan la pobreza y la posibilidad de su superación, que son los enfoques de capital humano y de capacidades humanas. El enfoque del capital humano se centra exclusivamente en la faceta económica de la pobreza; en esta perspectiva, la pobreza se define como la falta de dinero y puede abordarse mediante el aumento de los ingresos financieros de las personas que viven en la pobreza. El enfoque de las capacidades humanas ve la pobreza como un problema multidimensional que va más allá de la economía para áreas como la salud, la educación y la libertad. Este enfoque se orienta hacia el cambio social y ayudar a las personas en situación de pobreza para descubrir y desarrollar su potencial. El autor considera que las capacidades humanas abarcan con mayor precisión el alcance de la pobreza y las personas afectadas por el mismo, aunque debido a su amplia gama ha sido difícil diseñar e implementar políticas eficaces que aborden todas las facetas de la pobreza.

Bibliometría

A principios de 1990, los documentalistas comienzan a interesarse en hacer aplicaciones matemáticas y estadísticas en las unidades bibliográficas. F. J. Coles y Nellie B. Eales en 1917 hicieron el primer estudio con un grupo de títulos de documentos cuyo análisis consideraba el país de origen (White, p. 35). En 1923, E. Wyndham Hulme fue la primera persona en usar el término "estadísticas bibliográficas".Y propuso la utilización de métodos estadísticos para tener parámetros que sirvan para conocer el proceso de la comunicación escrita y, la naturaleza y curso del desarrollo de una disciplina. Para lograr ese aspecto empezó contando un número de documentos y analizando varias facetas de la comunicación escrita empleada en ellos (Ferrante, p. 201). En un documento escrito en 1969, Alan Pritchard propuso el término bibliometría para reemplazar el término "estadísticas bibliográficas" empleado por Hulme, argumentando que el, término es ambiguo, no muy descriptivo y que puede ser confundido con las estadísticas puras o estadísticas de bibliografías. El definió el término bibliometría como la aplicación de la matemática y métodos estadísticos a los libros y otros documentos (p. 348-349). Y desde ese momento se ha utilizado este término.

Les stratégies syndicales face aux restructurations d’entreprises : une étude comparative des contre-pouvoirs syndicaux dans le secteur des équipementiers automobiles en France et au Canada

Cette thèse tente de comprendre l’impact des restructurations des entreprises multinationales sur les stratégies syndicales. Les acteurs syndicaux locaux sont-ils déterminés par l’appartenance à des régimes nationaux et à des contingences organisationnelles ou peuvent-ils influencer des décisions objectives comme les restructurations ? Cette recherche s’insère dans une problématique large qui fait la jonction entre la mondialisation économique sur une base continentale, la réorganisation productive des entreprises multinationales et l’action syndicale. Au plan théorique, nous confrontons trois grandes approches analytiques, à savoir : le néo-institutionnalisme et les structures d’opportunités ; l’économie politique critique et la question du pouvoir syndical ; la géographie économique critique mettant de l’avant les contingences, l’encastrement et l’espace concurrentiel. Sur la base de ces trois familles, nous présentons un modèle d’analyse multidisciplinaire. Au plan méthodologique, cette thèse est structurée autour de quatre études de cas locales qui ont subi des menaces de restructurations. Cette collecte a été effectuée dans deux pays (la France et le Canada) et dans un secteur particulier (les équipementiers automobiles). Trois sources qualitatives forment le cœur empirique de cette thèse : des statistiques descriptives, des documents de sources secondaires et des entretiens semi-dirigés (44), principalement avec des acteurs syndicaux. L’analyse intra et inter régime national éclaire plusieurs aspects de la question des stratégies syndicales en contexte de restructurations. Les principales contributions de cette thèse touchent : 1. l’impact des facteurs relationnels et des ressources de pouvoir développées par les syndicats locaux sur les structures d’opportunités institutionnelles; 2. l’importance des aspects « cognitifs » et d’envisager le pouvoir de manière multi-niveaux; 3. l’importance de l’encastrement social et des dynamiques relationnelles entre syndicats et patronats; 4. l’influence de la concurrence internationale/nationale/régionale/locale dans le secteur des équipementiers automobiles; et 5. l’importance des arbitrages et des relations entre les acteurs de l’entreprise par rapport à la théorie de la contingence pour comprendre les marges structurelles des syndicats locaux. Notre recherche invite les acteurs sociaux à repenser leur action dans le cadre des restructurations. En particulier, les syndicats locaux se doivent d’explorer de nouveaux répertoires stratégiques pour répondre aux nombreux défis que posent le changement économique et les restructurations.

O desenvolvimento e as transições da carreira atlética dos jogadores de futebol de elite : estudo de caso num contexto de Seleção Nacional

A compreensão do desenvolvimento da carreira atlética e, em particular, das estratégias de ajustamento dos desportistas aos momentos de mudança no seu percurso de envolvimento no desporto, é fundamental para desenhar as facetas dos contextos promotores do talento, às quais a investigação tem vindo a destacar uma atenção especial nas últimas décadas. Nesse sentido, este estudo teve como objetivo descrever o processo de desenvolvimento e transições da carreira de futebolista de elite, esclarecendo as principais características e vivências ao longo do seu percurso desportivo. Para o efeito, foram realizados três estudos onde se incluem uma revisão sistemática de literatura e dois estudos de caso, com recurso a entrevistas semiestruturadas a 11 atletas de elite retirados que exercem funções nas seleções nacionais de futebol. Os resultados esclarecem o papel da prática precoce e diversificada, do suporte parental e da relação com o treinador como determinantes da carreira atlética. A participação em atividades desportivas informais e diversificadas é percecionada como promotora do desenvolvimento de competências técnicas e de relacionamento com pares, enquanto a especialização é observada como potenciadora, sobretudo, das competências de nível motor. Ao contrário de outros estudos realizados, as transições de júnior para sénior e do término da carreira foram identificadas como processos que não constituíram uma ameaça para os futebolistas. Finalmente, conclui-se que os atletas de elite vivenciam grandes dificuldades em conciliar as atividades académicas com a prática do futebol e o risco de abandono dos estudos surge regularmente associado à aproximação da subida ao escalão sénior pelo aumento da exigência e do investimento numa carreira profissional.

Electron tomography of (In,Ga)N insertions in GaN nanocolumns grown on semi-polar (11(2)over-bar2) GaN templates

We present results of scanning transmission electron tomography on GaN/(In,Ga)N/GaN nanocolumns (NCs) that grew uniformly inclined towards the patterned, semi-polar GaN( 112̄ 2 ) substrate surface by molecular beam epitaxy. For the practical realization of the tomographic experiment, the nanocolumn axis has been aligned parallel to the rotation axis of the electron microscope goniometer. The tomographic reconstruction allows for the determination of the three-dimensional indium distribution inside the nanocolumns. This distribution is strongly interrelated with the nanocolumn morphology and faceting. The (In,Ga)N layer thickness and the indium concentration differ between crystallographically equivalent and non-equivalent facets. The largest thickness and the highest indium concentration are found at the nanocolumn apex parallel to the basal planes.

Women Creators: Artistry and Sacrifice in the Novels of Virginia Woolf

This thesis examines different facets of feminine artistry in Virginia Woolf's novels with the purpose of defining her conception of women artists and the role sacrifice plays in it. The project follows characters in "Mrs. Dalloway," "To the Lighthouse," and "Between the Acts" as they attempt to create art despite society's restrictions; it studies the suffering these women experience under regimented institutions and arbitrary gender roles. From Woolf’s earlier texts to her last, she embraces the uncertainty of identity, even as she portrays the artist’s sacrifice in the early-to-mid twentieth century, specifically as the creative female identity fights to adapt to male-dominated spaces. Through a close-reading approach coupled with biographical and historical research, this thesis concludes that although the narratives of Woolf's novels demand the woman artist sacrifice for the sake of pursuing creation, Woolf praises the attempt and considers it a crueler fate to live with unfulfilled potential.

Acceptance of smartphone-based mobile shopping:mobile benefits, customer characteristics, perceived risk and the impact of application context

Despite their generally increasing use, the adoption of mobile shopping applications often differs across purchase contexts. In order to advance our understanding of smartphone-based mobile shopping acceptance, this study integrates and extends existing approaches from technology acceptance literature by examining two previously underexplored aspects. Firstly, the study examines the impact of different mobile and personal benefits (instant connectivity, contextual value and hedonic motivation), customer characteristics (habit) and risk facets (financial, performance, and security risk) as antecedents of mobile shopping acceptance. Secondly, it is assumed that several acceptance drivers differ in relevance subject to the perception of three mobile shopping characteristics (location sensitivity, time criticality, and extent of control), while other drivers are assumed to matter independent of the context. Based on a dataset of 410 smartphone shoppers, empirical results demonstrate that several acceptance predictors are associated with ease of use and usefulness, which in turn affect intentional and behavioral outcomes. Furthermore, the extent to which risks and benefits impact ease of use and usefulness is influenced by the three contextual characteristics. From a managerial perspective, results show which factors to consider in the development of mobile shopping applications and in which different application contexts they matter.

A multidimensionalidade da adaptação escolar na pré-adolescência

A presente investigação procura fomentar a reflexão e a compreensão do fenómeno da adaptação escolar. Partindo da exploração da literatura e de um conjunto de pressupostos teóricos de ordem desenvolvimental e ecológica, foi concetualmente delineado e testado um modelo multidimensional de adaptação escolar na pré-adolescência. O modelo examina principalmente dimensões sociais, mas também a dimensão académica e o nível socioeconómico familiar, propondo uma visão integrada da adaptação escolar. O estudo empírico desenvolveu-se junto de 706 estudantes pré-adolescentes e avaliou as perceções do próprio estudante e as perceções dos professores e pares acerca da competência social dos estudantes. O teste empírico ao Modelo de Adaptação Escolar evidencia um ajustamento global razoável, suportando as associações preconizadas entre as componentes da competência social e entre estas componentes sociais e a realização académica e o nível socioeconómico e cultural da família. Estes resultados sublinham a necessidade de considerar múltiplas facetas na avaliação e promoção da adaptação escolar, reconhecendo-se que esta engloba especialmente conexões entre a competência social e realização académica do estudante. Estes resultados serão ainda alvo de reflexão e discussão, sendo extraídas implicações para a investigação, teoria e intervenção.

What's so funny? An evaluation of the relations among humour use, mirth, and depressive symptomatology

Humour production and showing mirth (i.e., smiling and laughing) confer prosocial advantages. However, there is a paucity of literature evaluating how humour manifests in psychopathology. Humour and mirth may be especially relevant in depression, wherein profound impairments are evident in emotional and social functioning. Chapters 2 and 3 present correlational and predictive relations of depressive, social anxiety, and social anhedonia symptoms with humour styles, and consider the role of motivational systems and expressivity of positive affect as they relate to humour. As expected, symptoms and avoidance-based motivation were positively related to maladaptive humour styles and negatively related to adaptive humour styles. Interestingly, the pattern of relations shifted when considered among individuals in a depressive episode; acutely depressed individuals generally shy away from any humour style rather than gravitating toward specific styles. In a mediation model, the inverse relation between depressive symptoms and affiliative humour was fully mediated by approach-based motivation and expressivity of positive emotions. Chapters 4 and 5 examined subjective and observed mirth responses (facial affect and laughter) demonstrated by depressed and healthy comparison groups. Relative to non-depressed individuals, depressed persons reported less enjoyment, lower ratings of funniness, and fewer instances and shorter durations of positive facial affect and laughter when viewing humourous videos. There was no significant change in retrospective ratings of enjoyment and funniness at a one-week follow-up. The pattern of responsivity by depressed persons shifted when they viewed humourous videos while hearing others laughing. Both groups demonstrated more mirth when hearing others laugh; there were no differences between groups on mirthful behaviours. The one exception was that the total duration of laugher produced by depressed individuals was shorter than that produced by individuals in the healthy comparison group. This research project demonstrates that facets of depressive symptomatology are differentially associated with humour use and depressed individuals show blunted emotional responsivity to humourous stimuli. However, the pattern of reduced affective responsivity is context specific in that it fluctuates in response to hearing others’ laughter. These findings have important implications for the conceptualization of depression and the subsequent avenues for the treatment of individuals with depression.
