Abstract:

In the face of knowledge deficits in and poor outcome assessments of Organisation Transformation (OT), there is a need for a better understanding of the relationship between change leader interventions and qualitative organisational schema change, the collective knowledge structures that must be replaced or significantly elaborated if OT is to be realised. Previous research on this relationship has (a) focused on imposed structural interventions and given little attention to large-scale human process interventions, (b) given little attention to the radical structural interventions frequ

Abstract:

To lead an organization in change is complex. Leaders today struggle with how to adapt to the digital transformational change organizations are being exposed to. Digitalization forces leaders to go beyond the traditional way of leading when professions are getting automated. This requires leaders to engage subordinates in the leadership to handle a transformational change since both subordinates and leaders are expected to adapt to technological development. Here is when the role of shared leadership becomes preferable. To investigate this complexity in the banking industry, a case study has b

Abstract:

When integrating sustainability, companies are often overlooking the changes needed in their organisational culture. This hinders organisations’ core business to efficiently embed sustainability and dooms corporate sustainability initiatives to be superficial. A possible solution is for organisations to develop a sustainability- oriented organisational culture that engages employees with the sustainability change and that develops a leadership supportive of the engagement of their employees. As a result, this thesis aims at exploring how organisations can change their organisational culture in

Abstract:

Following exposure to consistent stimulus–stop mappings, response inhibition can become automatised with practice. What is learned is less clear, even though this has important theoretical and practical implications. The main contribution of this thesis is to investigate how stimulus-stop associations are acquired and the conditions under which they influence behaviour. To this end, this thesis addressed several outstanding issues concerning the associative architecture of stop learning, the role of expectancies, and the specificity of learning in inhibition tasks.

Although the importance of such shared ideas is often pointed out by practitioners as well as researchers within the field of school development, there is little consensus about their meaning. When it comes to questions about the actual function and character of such an idea, or set of ideas, little guidance is found

The purpose of this work is to explore a method that combines both top-down and bottom-up elements to fabricate electronic devices made from graphene, a single sheet of carbon atoms related to carbon nanotubes and graphite.

However, its lack of a band gap, and a lack of viable options for creating one in the material, suggests a limited future as a silicon replac

From the bottom-up approach (independent of string theory), using Bayesian inference techniques, we make the first complete model-independent scan of the low energy phenomenological MSSM (pMSSM) parameter space.

Abstract:

This dissertation concerns itself with the problem of constructing multi asset class portfolios. The investment process is aimed at solving two problems. The first problem is estimating the future returns of individual securities, which is an exercise fraught with uncertainty as the future is fundamentally unpredictable. This uncertainty means that the investor must allocate his portfolio to a number of assets instead of just one, in case his predicted future returns do not materialize. This leads the investor to the second problem of how best to construct the portfolio. It is this part of the

Abstract:

The prevalent view in computer vision since Marr is that visual perception is a data-driven bottom-up process. In this view, image data is processed in a feed-forward fashion where a sequence of independent visual modules transforms simple low-level cues into more complex abstract perceptual units. Over the years, a variety of techniques has been developed using this paradigm. Yet an important realization is that low-level visual cues are generally so ambiguous that they could make purely bottom-up methods quite unsuccessful. These ambiguities cannot be resolved without taking account of high-

Abstract:

Le travail présenté est une contribution au développement de dispositifs pour la nanoélectronique en associant les techniques de fabrication top-down et bottom-up. Notre choix s'est porté sur l'intégration de nano-objets (réseau 3D ou 2D ou bien objet unique) dans un dispositif à géométrique planaire composé de deux électrodes séparées par un intervalle nanométrique. Nous présentons tout d'abord les différents procédés technologiques (basé principalement sur la lithographie électronique) utilisés pour la fabrication de nanoélectrodes métalliques (or) ou métalliques magnétiques (cobalt) sur un

Abstract:

Background: Although several neurophysiological models have been proposed for panic disorder with agoraphobia (PD/AG), there is limited evidence from functional magnetic resonance imaging (fMRI) studies on key neural networks in PD/AG. Fear conditioning has been proposed to represent a central pathway for the development and maintenance of this disorder; however, its neural substrates remain elusive. The present study aimed to investigate the neural correlates of fear conditioning in PD/AG patients. Method: The blood oxygen level-dependent (BOLD) response was measured using fMRI during a fear

Abstract:

Democracy promotion is a key objective in both US and EU foreign development policy. The study attempts to provide a better understanding of both actors democracy promotion in Afghanistan. The US and the EU are perceived to have different approaches regarding democracy promotion. Therefor the study examines if US used top-down and EU bottom-up approaches respective coercive and persuasive methods. Approaches used by actors are examined in the study regarding democracy promotion in the case of Afghanistan. It is a case study with qualitative text analysis and the theories used are top-down and

Abstract:

Today, activities funded with public funds needs to present relevant and reliable information which shows the results obtained. Requirements increase in welfare activities to be run based on scientific, empirical knowledge. This applies particularly to social work. The social work is, however, poorly researched in areas such as knowledge of interventions in the content, context and effects. One way to evidence-base social work can be to conduct regular and qualified assessments. To evaluate, however, is complex, and knowledge of the evaluations are deficient in those who plan and execute them.

Abstract:

This dissertation aims to discover synergistic combinations of top-down (ontologies), interactive (relevance feedback), and bottom-up (machine learning) knowledge encoding techniques for text mining. The strength of machine learning techniques lies in their coverage and efficiency because they can discover new knowledge without human intervention. The output, however, is often imprecise and irrelevant. Human knowledge, top-down or interactively encoded, may remedy this. The research question addressed is if knowledge discovery can become more precise and relevant with hybrid systems. Three dif
