Three papers laying the foundation for regional CGE models with agglomeration characteristicsTermansen, Lars Brømsøe (Frederiksberg, 2008)[More information][Less information]
Abstract: The paper analyses the effects of introducing taxes and regional transfers on the equilibrium properties in a standard Core-Periphery model. A central government levies taxes on production factors and redistributes the revenue to all agents regardless of their location. In the case of Core-Periphery economy this is in effect a re-allocation of agglomeration rents. Simulations show that taxes and transfers alter the Core-Periphery model’s properties by moving the Break and Sustain points. The range of freeness of trade with Core-Periphery outcomes is reduced for transfers to the periphery, and increased for transfers to the core. The width of the overlap where the models exhibit hysteresis effects remains the same regardless of the transfers. The analysis reveals that in the Core-Periphery outcome the agglomeration rents can be taxed without exhausting the core’s scale effects. The tax revenues can then be redistributed such that periphery regions and the central government have incentives in promoting core regions, which function as industrial locomotives for the whole economy.

The Case of U.S. Chambers of CommerceCrawford, Brett (Frederiksberg, 2012)[More information][Less information]
Abstract: Much of the organizational institutionalism literature suggests that the phenomenon of interests is a central construct, however, portrays interests in an overly deterministic, rational, and liberal way. In this thesis, I challenge those views and suggest that interests are a complex and interdependent socially constructed phenomenon. Accordingly, interests represent an actor’s recognition, perceived importance, and participation in a number of figurations and social games. Illustrated through the institution of U.S. chambers of commerce, I explore how chambers of commerce have withstood a changing American culture to become both the world’s largest business federation and public-private partnership. Moreover, even as the United States represents the most liberal of liberal market economies, chambers of commerce represent a context where capitalists have set aside market competition and unified their interests to become one of the largest and most influential institutions in the world. Following a brief introduction of interests and chambers of commerce, this thesis begins with the first paper, which is a critical review of the phenomenon of interests within the organizational institutionalism literature. Tracing the conceptual variety of both the origins and functions of interests in institutional studies, I illustrate how an overly deterministic and rational view of interests is problematic. The critical review continues with a discussion of my critiques of the extant literature followed by an introduction of a less rational and calculative approach to interests by coupling Bourdieu’s (1998) conceptualization of interests with Elias’s (1978) sociology emphasizing figurations and social games. The three subsequent empirical papers test this approach to interests on macro-, meso-, and micro-levels of the institution of chambers of commerce.

Abstract: This Ph.D. thesis is concerned with the role of the business intelligence (BI) output in organizational decision-making processes. The primary focus of this thesis is to investigate how this BI output is employed and deployed by decision-makers to shape collective judgement and to reach organizational decisions. Concerning the role of the BI output in decision-making the BI literature is characterized by normative ideas of how the BI output should be used in decision-making and how it can enable people to make better decisions. Most previous work has concerned methods and technologies to collect, store and analyze BI. It has also, assumed a rational approach to decision making where data from information systems are used to inform decisions either by reducing uncertainty, ambiguity or complexity. This study attempts to establish knowledge about the role of the BI output in the IT project prioritization process of the Group IT of the Danske Bank Group. Hence, the starting point of this thesis is a 16-month long interpretive study from March 2010 till July 2011 during which I observed the prioritization process and collected various forms of data. I use a rich dataset built from this longitudinal study of the IT project prioritization process in Group IT where thematic analysis is used to analyze the data. Overall, the study operates under the interpretive paradigm, which assumes that the world and knowledge are socially constructed. URI: http://hdl.handle.net/10398/8664 Files in this item: 1

En analyse af coachingsdiskursens genealogi og governmentalityHede, Tobias Dam (Frederiksberg, 2011)[More information][Less information]
Abstract: Formålet med denne afhandling er at undersøge coachingdiskursens genealogi og ”governmentality”, dvs. dens historiske formationer og normative basis som ledelsesmodel og praksisregime. Problemfeltet formuleres igennem det såkaldte ”symmetriproblem”. Den væsentligste udfordring heri er spørgsmålet om, hvordan en coach kan bistå et andet menneske med at åbne sig for og vende sig imod det, der er væsentligt for den enkelte selv, og det fællesskab, han eller hun definerer sig i forhold til. I det perspektiv er symmetriproblemets analysestrategiske funktion at være samlebetegnelse for tre ”problematiseringslinjer” i coachingdiskursens genealogi og governmentality, der konstituerer sig igennem diskursive strategier for: 1) Ledelse, 2) erkendelse og 3) subjektivitet. Ud fra det perspektiv besvarer afhandlingen følgende research question: Hvordan problematiseres, idealiseres og tilegnes coaching som samtalekunst og ledelsesdisciplin på baggrund af symmetriproblemet? Afhandlingens formål og problemfelt vil i det følgende blive udfoldet i en mere generel indledning ud fra fem overskrifter: 1) Motivation af problemfeltets tilblivelse, aktualitet og relevans; 2) analysestrategisk greb; 3) genstandsfelt; 4) erkendelsesinteresser og forskningsbidrag, samt 5) analysestrategiens disposition og empiriske design.

Abstract: The regulatory approach to supply security in electricity markets has been substantially altered since power markets were partly privatized and reregulated in the mid 1990’s, when regulators chose to rely on market based prices and decentralized commercially based decisions on generation capacities. Prior to this market restructuring power systems basically worked as planned economies, however, the decentralization of production decisions introduced stochastic elements to electricity systems. Additionally, since the early 2000’s, power generating companies, often incentivized by the state, started increasing the share of renewable but intermittent energy sources in their generation portfolios. Due to its intermittency the production process of wind, solar and hydro power is difficult to plan and therefore the final amount of power that enters the market at each point in time becomes difficult to predict. As the level of power supply intermittency increases, so also do the number of challenges that market based approaches face in organizing secure power systems....

En socialpsykologisk analyse af forholdet imellem selvledelse, ledelse og stress i det moderne arbejdslivGroth-Brodersen, Signe (Frederiksberg, 2013)[More information][Less information]
Abstract: Afhandlingen rejser et kritisk perspektiv på individualiseringen af sundhedsfremme ud fra en diskussion af ledelse af selvledelse i det moderne arbejdsliv. Det er karakteristisk for den eksisterende danske og internationale forskning i selvledelse, at der er gennemført en begrænset empirisk udforskning af selvledelsens funktion og virke i arbejdslivets praksis. Det er i særlig grad empirisk underbelyst, hvordan variationer i forholdet imellem selvledelse og ledelse indvirker på forekomsten af stresssymptomer. Et nyere dansk empirisk projekt placerer selvledelse, beskrevet som en særlig form for selvorganiseringskompetence, i en positiv position i forhold til at håndtere det grænseløse arbejdsliv. Det grænseløse arbejdsliv beskrives her som det at have frie grænser i forhold til organiseringen af ’arbejdstid og arbejdssted’. Disse resultater udfordrer tidligere studier indenfor arbejdslivsforskning, hvor man i højere grad har set selvledelse koblet sammen med stress og stigende krav til individet (Phil-Tingvad, 2010; Allvin et. al., 2011, Lund & Hvid, 2007). I den internationale forskning beskrives selvledelse som ’Self-Leadership’. Self-Leadership handler om en særlig form for selvkontrol, hvor individet giver sig selv feedback og er selvmotiverende (Neck & Hougton, 2006; Manz & Neck, 2004). Self-Leadership er en teori, der arbejder med selvledelse uden en konkret kobling til arbejdslivet. Teorien beskæftiger sig derfor ikke med selvledelsens sammenspil med ledelsen og herunder betydningen af ledelse som relevant kontekstuelt parameter. Selvledelse bliver set som en eksistentiel form for egenledelse.... URI: http://hdl.handle.net/10398/8626 Files in this item: 1

An implementation and evaluationHalskov, Jakob (København, 2008)[More information][Less information]
Abstract: The research object of this thesis is the so-called knowledge patterns and their usefulness in automatically extracting specic semantic relations from unannotated and uncategorized text on the WWW so as to facilitate semi-automatic updating and extension of existing ontological and terminological resources. The main contribution of the thesis is the implementation of a com- plete ontology extension framework called WWW2REL which is 100% based on a knowledge-poor, domain-independent processing of WWW text snippets and includes the three stages of pattern discovery, pattern ltering and relation instance ranking. Unlike most comparable systems WWW2REL is special in that it is both highly portable, can be applied to any semantic relation type and operates directly on uncategorized WWW text snippets. The system is tested on the biomedical UMLS Metathesaurus for four dierent relation types and manually evaluated by four domain experts. It is demonstrated that high precision in the task of knowledge discovery from a noisy text source can be achieved using a very simple instance relevance measure and two ranking heuristics. In contrast, many comparable systems operate on richly annotated academic text and tend to apply heuristics which are custom-tailored to a specic domain and/or relation type. When selecting the overall best ranking scheme, average system performance across all four relation types ranges between 70% to 65% of the maximum possible F-score by top 10 and top 50 relation instances, respectively. Finally, the thesis experiments also examine the portability of individ- ual knowledge patterns and of the ranking heuristics. It is concluded that synonymy KPs are the most domain independent closely followed by ISA KPs, whereas patterns for "may_prevent" and especially "induces" are more dependent on the domain. Empirical experiments also suggest that a ranking heuristic which penalizes relation instances whose arguments occur frequently in a general language corpus can be highly eective, but may need to be adapted to the domain in question.

How do sensemaking processes with minimal sharing relate to the reproduction of organised action?Murphy, Tine (Frederiksberg, 2009)[More information][Less information]
Abstract: The thesis examines an underexplored area in sensemaking theory. The theme for the thesis is to examine the relation between sensemaking and the reproduction of organised action. Existing sensemaking theory focusses on how shared organising processes support the reproduction of organised action (Smircich & Morgan, 1986; Smircich & Stubbart, 1985; Weick, 2004; Maitlis, 2005; Donnellon et al, 1986). This thesis' contribution is to examine sensemaking processes which do not spring from shared articulation within the formal organisation and these processes' relation to the reproduction of organised action. In the thesis the phenomenon is illustrated with a case consisting of a younger voluntary organisation (called the Network Group) whose purpose is to provide tuition for children with another ethnic background than Danish. The organisation survives and meets its purpose. This, however, takes place largely without the voluntary tutors talking with each other to make sense of their shared action. This falls outside the expectations produced in the greater part of existing sensemaking theory. Apart from the relevancy for organisation theory, the interest in the phenomenon organised action with limited shared sensemaking and limited shared articulation – comes from a hypothesis that actors in latemodernity will be less inclined to invest in shared sensemaking because they zap between organisational contexts (Bauman 2000, Beck 1986, Beck & BeckGernsheim 2002 and Bellah et al 1985). This is a phenomenon which has drawn particular attention within the Danish voluntary sector in the last 10 years (Isen1, 1999; Goul Andersen et al, 2000; Hermansen & Stavnsager, 2000; Stavnsager & Jantzen, 2000; Christensen & Isen, 2001; Børch & Israelsen, 2001; Wollebæk & Selle, 2002; Nielsen et al 2004; Murphy 2004). Similar concerns in the U. S. are most notably expressed by Putnam (1990) in the book “Bowling Alone”. In Denmark the phenomenon is linked to perceived difficulties with filling positions at boards of voluntary organisations with younger volunteers.

A Neoinstitutional Analysis of the Emerging Organizational Field of Renewable Energy in ChinaHøyrup Christensen, Nis (Frederiksberg, 2013)[More information][Less information]
Abstract: Today, China is the world leading investor in renewable energy. At the heart of this effort lies China’s ability to shape markets through industrial policies. Through a neoinstitutional theoretical perspective this dissertation views China’s efforts within renewable energy as the emergence of a new organizational field. Despite the importance of organizational fields as a key concept in the neoinstitutional literature, there is a lack of studies on exactly how they emerge. Throughout four articles this dissertation scrutinizes therefore the emergence of the field of renewable energy in China and the mechanisms driving this emergence. Firstly, the relation between state and market is examined, and it is argued that Chinese state interventions in markets, for instance through subsidies, are based in deeply rooted historic grounds. Thus, the article explains the general context in which the Party-state handles subsidized markets, like renewable energy. Secondly, the specific development of the idea of sustainable development, and how it evolves into an institutional logic of its own, is analysed. It is around this institutional logic that renewable energy emerges as a field. The key mechanism in play is the idea work of the Party state by which sustainable development is positioned in the Partystate discourse. Thirdly, subsidization of renewable energy in China is examined as an important feature of the increasing institutionalization of the organizational field. It is shown how negotiation between companies and Party-state is the vital mechanism by which subsidies are determined.... URI: http://hdl.handle.net/10398/8627 Files in this item: 1

Enhancing Social Entrepreneurship and Stakeholder TheoryDacanay, Marie Lisa (Frederiksberg, 2012)[More information][Less information]
Abstract: This thesis develops a framework for understanding how social enterprises engage the poor and address poverty, a pressing global problem of the 21st century. Using casebased theory building, it studies a theoretical sample of three pairs of Philippine-based social enterprises, where the poor were suppliers, workers, and customers. In half of the cases, the poor were also owners. The research studies the roles and role changes of the poor in these social enterprises, how and why these roles changed, or did not change, and the impact of the roles and role changes, if any, on the social enterprises and the poor. Data for the research was gathered mainly from key informant interviews, published and unpublished organizational documents as well as previous studies done by external consultants on the case subjects. Based on a cross case analysis of the data from the theoretical sample, the thesis develops three models of stakeholder engagement among social enterprises with the poor as primary stakeholders or SEPPS, namely: control, collaboration and empowerment. This thesis provides insights and develops propositions about the importance of stakeholder engagement and the power and limitations of these three models in bringing about social inclusion and poverty reduction. These propositions are suggested to be applicable in countries in the South other than the Philippines where systemic poverty and inequality are exacerbated by the failure of state and market institutions to address the needs of the poor. This thesis makes a contribution to social entrepreneurship and stakeholder theory. It does so by sharing a perspective from the South and giving a voice to the poor as stakeholders. The researcher notes that overall, the poor and the South are under-represented in these discourses. On the whole, social entrepreneurship theorizing has been characterized as embryonic as a topic of academic inquiry. Stakeholder engagement is considered an under-theorized area in stakeholder theory. In developing a framework for understanding stakeholder engagement models involving the poor, this thesis makes a first step towards applying and extending stakeholder theory in SEPPS. The thesis likewise enriches social entrepreneurship theory by conceiving of SEPPS as a global social enterprise model that catalyzes South-North cooperation to address poverty and inequality.

Et mixed method studie, der belyser læringskonsekvenser af et lederkursus for et praksisfællesskab af offentlige mellemledereMoesby-Jensen, Cecilie K. (Frederiksberg, 2010)[More information][Less information]
Abstract: The English title of this dissertation, which in the outset was an integrated part of a larger intervention study on the effects of team manager training, is: Social learning and shared practice. A mixed method study showing the learning consequences of a training course for a community of practice of public middle managers. Due to the growth of the elderly population in Denmark and, simultaneously, the fact that a large part of Danish health care workers soon face retirement, in addition to the challenge regarding the recruitment and the holding on to employees in the public health care sector in Denmark in the coming years, this sector is confronted with the task of creating and sustaining sought-after workplaces and one way of doing this is by organizing the work in a efficient and attractive way for the employees, for instance in compliance with the idea of teamwork. This entails change, education and learning, and this dissertation investigates, in a case-study, the social learning consequences of a training course for middle managers in the Danish health care system, and thus poses the research question: What are the intended and unintended learning consequences of the training course ”Managing teams”?....

Change management challenges in the Danish police reformDegnegaard, Rex (Frederiksberg, 2010)[More information][Less information]
Abstract: Since its commencement in January 2007, the Danish police reform has been a hot topic in the media, at universities, dinner parties, and in waiting rooms. The general perception of the police reform is that it is a failure. During 2008, the reform has been subject to much public debate, which has linked many unfortunate cases of police neglect with the police reform. Furthermore, the public debate has created a picture of a police not in control and with the reform to blame. Given this troublesome context of the police reform, the question which everyone is asking is: why did it go wrong? Along with the question of: whose fault was it? The current thesis does not provide one single answer to the chaotic situation surrounding the police reform. Neither does it place the responsibility of the unforeseen consequences of the police reform. Rather, this thesis focuses on unforeseen consequences of the reform in regards to change management and organizational implications. This thesis is submitted as a doctoral thesis at Copenhagen Business School in completion of a three-year Ph.D. study. The thesis is the result of a longitudinal research study on change management challenges in the Danish police reform. The study rests on a multi-sited methodology compromising an array of research methods such as interviews, field studies, presentations, meetings, written document studies, etc. over the course of the three years’ duration of the study. The study draws from different strands of literature, primarily change management literature and institutional literature, including resource dependency theory. The research question, which guides the thesis, is as follows: What are the change management challenges and the organizational implications of introducing a reform, which has a functional-rational logic of modernization and efficiency to the Danish police, which is a strongly institutionalized organization? The research question has been answered through the analysis, which is divided into three sections: - Change management in the reform, - Content of the police reform, and - The external control of the police.

Kinra, Aseem (Frederiksberg, 2009)[More information][Less information]
Abstract: The spatial scope of organisations has recently been reemphasised in the context of supply chains and supply chain management. This scope is usually accompanied by uncertainty to organisations, especially for the extended supply chain with geographically dispersed operations and activities, thus posing environmental complexity in the form of risks and costs that organisations need to contend with. The main purpose of this dissertation is to create a deep understanding of this environmental complexity facing the extended supply chain, and the main research objective is to develop a construct, consisting of factors and measures, that can aid in describing its state in the context of logistics. Overall, the dissertation assumes an international business (IB) standpoint in undertaking this task whereby it is argued that countries and borders matter, and that differences between country environments lead to environmental complexity in the geographically dispersed supply chain. Country-oriented constraints may then exist at macro-economic level, or the micro-/meso- e.g. firm, network and industry levels of the business environment. In this dissertation, supply chain (logistics) environmental complexity is developed and operationalised in terms of the range and heterogeneity of country-oriented macro- logistics factors that need to be considered in extended, cross-border, or global supply chain (logistics) operations. The remainder of this dissertation is thereafter dedicated to finding these factors, and their respective information measures, by the application of a decision-making approach. A decision factor is one that influences the decision on selection with regards to environmental complexity, and an information measure is a unit of measurement that aids decision-making by providing some information on the factor. The findings of this dissertation are based upon multiple literature reviews, content analyses and expert opinions, and suggest the importance of 17 such decision factors and 187 different types of information measures, which describe the state of environmental complexity in extended, cross-border, or global supply chain operations. The study is particularly relevant from the perspective of strategy and design issues in global supply chain management, international operations management and international business, and more specifically for environmental scanning and decision-making applications such as site location and transport mode selection. By applying the results of this dissertation decision-makers may, for example, get a preliminary idea of the environmental complexity surrounding their extended supply chains.

Abstract: Reordering has been an important topic in statistical machine translation (SMT) as long as SMT has been around. State-of-the-art SMT systems such as Pharaoh (Koehn, 2004a) still employ a simplistic model of the reordering process to do non-local reordering. This model penalizes any reordering no matter the words. The reordering is only selected if it leads to a translation that looks like a much better sentence than the alternative. Recent developments have, however, seen improvements in translation quality following from syntax-based reordering. One such development is the pre-translation approach that adjusts the source sentence to resemble target language word order prior to translation. This is done based on rules that are either manually created or automatically learned from word aligned parallel corpora. We introduce a novel approach to syntactic reordering. This approach provides better exploitation of the information in the reordering rules and eliminates problematic biases of previous approaches. Although the approach is examined within a pre-translation reordering framework, it easily extends to other frameworks. Our approach significantly outperforms a state-of-the-art phrase-based SMT system and previous approaches to pretranslation reordering, including (Li et al., 2007; Zhang et al., 2007b; Crego & Mari˜ no, 2007). This is consistent both for a very close language pair, English-Danish, and a very distant language pair, English-Arabic. We also propose automatic reordering rule learning based on a rich set of linguistic information. As opposed to most previous approaches that extract a large set of rules, our approach produces a small set of predominantly general rules. These provide a good reflection of the main reordering issues of a given language pair. We examine the influence of several parameters that may have influence on the quality of the rules learned. Finally, we provide a new approach for improving automatic word alignment. This word alignment is used in the above task of automatically learning reordering rules. Our approach learns from hand aligned data how to combine several automatic word alignments to one superior word alignment. The automatic word alignments are created from the same data that has been preprocessed with different tokenization schemes. Thus utilizing the different strengths that different tokenization schemes exhibit in word alignment.

en analyse af diskussionen omkring indførelse af EPJ på en hospitalsafdelingSchnack, Morten (København, 2008)[More information][Less information]
Abstract: The aim of this thesis is to analyse how the implementation of electronic patient records (EPR) may affect cross-disciplinary clinical practice in a particular hospital department. The thesis presents a modified discourse analysis, a technology analysis, and some reflections on power. Using nineteen interviews of doctors and nurses in the Paediatric Department of Hvidovre Hospital, it emphasizes those actions in relation to the implementation of EPR that may either hinder or foster cross-disciplinary co-operation between doctors and nurses. The general pattern is that EPR fosters mono-disciplinarity, even though the management’s ambitions in regard to EPR had been to foster crossdisciplinarity. The overall conclusion of the thesis is that EPR has the capacity to open a space for cross-disciplinarity. The changes in the documentation practices of the doctors and the nurses that follow from the implementation of EPR have also brought changes in their communication and decision-making processes. This can be seen especially when they prepare for regular rounds, during rounds, and in the subsequent documentation of rounds. Also, the changes in both the structures of communication and the processes of decision-making do not seem to result in fundamental task slippage between the doctors and the nurses because the doctor maintains ultimate authority and responsibility in regard to diagnosis, prescriptions, and treatment plans, while the nurses remain responsible for patient care (nursing) and keeping the doctors informed. Like the paper-based patient record, EPR expresses the rationality of medical science but, unlike the paper-based patient record, the doctors no longer hold a monopoly on the expression of this rationality. The thesis focuses on the spaces of conduct that arise as a result of the managing doctor’s political intention to use the transformation of patient record technology as an occasion for managers and professionals to reconsider how they have hitherto organized the routines and tasks in the department.

Abstract: The three essays study the US corporate bond market with special attention to bond liquidity. All essays are empirical studies which rely heavily on the availability of transactions data. Earlier studies had to use quoted bond prices for empirical studies, but with the introduction of the TRACE system and with the following dissemination of transaction prices the data quality on corporate bonds has improved immensely. In the years after 2000 a range of studies assessed the performance of structural credit risk models and found that they were not able to fully explain the size of the average credit spread for corporate bonds. Huang and Huang (2003) suggested (among others) that the remaining non-default-component of the credit spread was an illiquidity premium. Using transaction data this thesis studies the impact of illiquidity and trading frictions on corporate bonds. URI: http://hdl.handle.net/10398/8198 Files in this item: 1
