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. We achieve a 38% error reduction for the automatic word alignment URI: http://hdl.handle.net/10398/7922 Files in this item: 1

Approaches to Knowledge Management PracticeSanchez, Ron (København, 2004)[More information][Less information]
Abstract: This paper explains two fundamental approaches to knowledge management. The tacit knowledge approach emphasizes understanding the kinds of knowledge that individuals in an organization have, moving people to transfer knowledge within an organization, and managing key individuals as knowledge creators and carriers. By contrast, the explicit knowledge approach emphasizes processes for articulating knowledge held by individuals, the design of organizational approaches for creating new knowledge, and the development of systems (including information systems) to disseminate articulated knowledge within an organization. The relative advantages and disadvantages of both approaches to knowledge management are summarized. A synthesis of tacit and knowledge management approaches is recommended to create a hybrid design for the knowledge management practices in a given organization.

Jeppesen, Soeren (, 2009)[More information][Less information]
Abstract: The international literature on Corporate Social Responsibility (CSR) has focused on large rms, in the North, mostly applying normative, universal and positivist approaches. However, over the last 10-15 years increasing attention has been directed towards micro, small and medium-sized rms, SMEs. While the focus on CSR in SMEs mainly has been con ned to a Northern context, limited, though growing, focus has been on CSR in SMEs in a Southern or developing country context. The paper assesses the contributions on CSR and SMEs in Development. It does so by presenting three dominant and con icting perceptions of SMEs in the CSR literature (SMEs as problems vs. SMEs as innovators; SMEs as miniature versions of large rms vs. SMEs in their own right; SMEs responding to voluntary approaches vs. SMEs responding to state regulation). The paper then takes stock of what we know about CSR, SMEs and Development (concerning environmental issues; labour, safety & health; global supply chains; and nally CSR and SMEs in Clusters) and what we don’t know. The paper nally argues in favour of a critical research based on a) focus on Southern perspectives, b) SMEs in their own right, and c) application of context-sensitive approaches. It advocates the key issues of a critical CSR in SMEs in Development research agenda should be focused at the interface between SME, CSR and Development issues. It presents four main parts or areas of such an agenda and three suggestions concerning policy initiatives, before it brie y concludes on the changes that the eld has undergone over the 10-15 years observed.

What Do We Know? Where Do We Go?Leca, Bernard; Battilana, Julie; Boxenbaum, Eva (København, 2006)[More information][Less information]
Abstract: This paper analyzes the literature that has been published on institutional entrepreneurship since Paul DiMaggio introduced this notion in 1988. Based on a systematic selection and analysis of articles, the paper outlines an emerging consensus on the definition and process of institutional entrepreneurship. It also presents the enabling conditions that have been previously identified and reviews the research methods that have been applied to the study of institutional entrepreneurship. Finally, based on this analysis, this paper highlights future directions for research on this topic. Researchers may use this paper to build targeted and sophisticated research designs that add value to the emerging body of literature on institutional entrepreneurship.

Abstract: This paper suggests that it is time to take the agency of teams seriously. Whereas the debate has previously focused on how firms may function more effectively by using team-based work-organization, our aim is to discuss and understand how teams effect the evolutionary dynamic of companies. Fieldwork in four Danish manufacturing companies helped us discover that firms as “communities of teams” are highly dynamic entities with complex layers of different team forms that operate, innovate and improve by constantly recombining work, collaborating across organizational divisions and redistributing authority, thereby challenging some of the existing “idioms” of team research and theories of the firm. The paper builds on these findings as we attempt to rethink research on teams by re-describing the evolutionary dynamics of firms and suggesting some themes that call for comparative research.

A Useful Way of Burning MoneyBechmann, Ken L.; Raaballe, Johannes (København, 2005)[More information][Less information]
Abstract: Firms pay out cash using both dividends and share repurchases. In many aspects these two means are similar, but one important difference is that dividends are generally taxed more heavily than share repurchases. Nevertheless firms persist in paying out large amounts in dividends. This paper provides an explanation for this dividend puzzle by developing a class of signaling models violating the "single-crossing" property in which information about the quality of the firm is asymmetric between the management and the shareholders. In these models a high-quality firm can always signal its quality by using share repurchases only. However, in certain cases share repurchases become costlier on the margin for a high-quality firm than for a low-quality imitator. In such cases, the high-quality firm signals most cost efficiently by means of a combination of share repurchases and taxable cash dividends financed by the issuance of new shares. Taxable cash dividends financed by the issuance of new shares then can be considered a positive kind of money burning whose role is to signal a firm’s high quality. The implications of the models are consistent with several important empirical facts about dividends and share repurchases. Thus, this paper’s main contribution is to examine a range of new signaling models that provides a role for taxable cash dividends and share repurchases and to derive their empirical implications.

Lund, Diderik (København, 2003)[More information][Less information]
Abstract: Abstract Lund (2002a) showed in a CAPM-type model how tax depreciation schedules affect required expected returns after taxes. Even without leverage higher tax rates implied lower betas when tax deductions were risk free. Here they are risky, and marginal investment is taxed together with inframarginal in an analytical model of decreasing returns. With imperfect loss offset tax claims are analogous to call options. The beta of equity is still decreasing in the tax rate, but increasing in the underlying volatility. The results are important if market data are used to infer required expected returns, and in discussions of tax design.

Abstract: In recent years, venture capital has increasingly become a factor in the financing of new firms. We examine how the value of mature firms determines the incentives of entrepreneurs to start up new firms and of venture capitalists to finance and advise them. We examine how capital gains taxes as well as subsidies to start-up costs of new firms affect venture capital-backed entrepreneurship. We also argue that dividend and capital gains taxes on mature firms have important consequences for start-up firms as well.

Abstract: We examine how a multinational’s choice to centralize or de-centralize its decision structure is affected by country tax differentials. Within a simple model that emphasizes the multiple conflicting roles of transfer prices in MNEs — here, as a strategic pre-commitment device and a tax manipulation instrument —, we show that decentralization is preferred in case of small tax differentials, whereas centralization can be more profitable, when tax differentials are large. In essence, the organizational flexibility of MNEs is triggered by the scope for tax minimization. Our analysis allows for both commitment and non-commitment to transfer prices, and for alternative modes of competition. Keywords: Centralized vs. de-centralized decisions, taxes, transfer prices, MNEs. JEL-Classification: H25, F23, L23. URI: http://hdl.handle.net/10398/7509 Files in this item: 1

Abstract: This paper provides an assessment of Greenland's tax system and contemplates changes that may be undertaken in the future to prepare for greater economic self-reliance and for the country's participation in the wider world economy. At the outskirts of Europe, Greenland is an autonomous part of the Danish kingdom, though currently not a member of EU. However, its cooperation with European countries and its dependency on international trade renders it necessary for the tax system in Greenland to be attuned to developments in the rest of the world. Drawing on a thorough international benchmarking analysis of Greenland's tax system, the paper's special focus will be on the corporate tax system and its interplay with personal taxation, as well on as the system of import duties. In particular, we carry out computations of effective marginal and average corporate tax rates, as well as average effective tax burdens on consumption, labour income and capital income, and compare these to similar measures for EU countries. In addition, we outline how Greenland's economic policy in other areas interferes with tax policy. Especially fishery regulation, management of government-owned companies, and housing policy have major implications for the tax system.

Abstract: In this paper I explore the constructive links between co-operation, rivalry, and learning within the structure of team communities. Drawing upon social learning theory, the main purpose of this paper is to argue that both co-operation and rivalry are important triggers for mobilizing learning processes within and between teams. However, social learning theory tends to disregard the positive aspects of rivalry. Consequently, this paper will argue for the need to extend social learning theory beyond its rather harmonious learning perspective. URI: http://hdl.handle.net/10398/7369 Files in this item: 1

Foss, Nicolai J. (Frederiksberg, 2011)[More information][Less information]
Abstract: A concern with teams was central to early attempts to grasp the nature of the firm, but fell out of favor in later work. We encourage a return to the emphasis on teams, but argue that the idea of teams as central to the nature of the firm needs to be grounded in an appreciation of the importance of We frames and group agency. We use converging insights from evolutionary anthropology, cognitive social psychology and work on team agency to develop such a grounding, and link it to the issues of the existence and boundaries of firms.

Abstract: A development in Information and Communication Technologies promising to have a large impact on tourism is the phenomenon known as the Web 2.0. A key to this development is the encouraging of interactivity due to User Generated Content (UGC). This paper focuses on a specific type of UGC: Tourist Created Content (TCC). Based on an exploratory examination of the Web and an extensive analysis of the content, the study systematizes the knowledge about TCC, presents a classification system and provides an overview of its characteristics. The paper shows the processes that allow the tourist to digitalize content and reveals how TCC relates to the cultures of the Internet and shapes the tourism experience.

Or how materials produce degrees of humanity in strategic research and practiceTryggestad, Kjell (København, 2003)[More information][Less information]
Abstract: The aim of this article is to inquire into the possible significance of materials in the production of emerging strategic outcomes. The article first sets out to discuss the different ways contemporary strategy research define the identity of strategic actors. It is argued that the various schools of strategy research, although different in important respects, operate with a common human centered assumption: Humanity is treated as given – the strategic actor or subject is assumed to be an individual human or a collective of humans. By adding the possible significance of materials and other non-human entities to the explanatory repertoire of strategy research, another line of inquiry is pursued. The performative perspective thus proposed, is inspired by the classical work of Von Clausewitz and the recent anthropology of science, technology and organizational identities. In the proposed perspective, the human centered assumption is no longer just a premise for doing strategy research, but instead considered an interesting emerging outcome to be explained. Further more, the performative perspective allows strategy research to extend the notion of emergent strategies so as to include the possible significance of materials and other non-human entities in the explanation of 2 emerging strategic identities and outcomes. Hence, also a new task has been added to strategy research: To explain how emerging strategic identities – consisting of both humans and non-humans, are produced as part of strategic outcomes. Three cases are presented, each of them with a particular bearing on how materials participate in the making of emerging strategic identities and outcomes: The first case account for strategies transforming plans into anti-plans. This is a case of how a strategic plan is betrayed (or rejected) by an emerging collective consisting of both humans and diverse materials like a paper inscription and heavy machinery. The second case account for how the emerging twin identities of the strategic management subject and the human object are co-produced in interaction with a machine delegate. Finally, the third case account for how the strategic technology and the strategic collective emerge and co-produce each other as a macro-actor, only to become transformed in unexpected ways - as common technology and reflective human subjects. In the concluding section, it is argued that the humanity of the reflective human subject should be regarded as an emerging identity, co-produced in interaction with diverse materials like machinery. It is further argued that strategy research has slowly written out Von Clausewitz original insight in this respect. The complexity Von Clausewitz introduced with the notion of ‘degrees of humanity’ has been replaced with a given humanity, yet the costs of doing so remain outside the frames of contemporary strategy research. Failing to attend to the possible significance of materials in producing degrees of humanity has made strategy research as much producers of strategic outcomes, as providers of explanations and observations. The expression ‘technological strategy as macro-actor’ summarizes these findings and the associated implications for research and practice. URI: http://hdl.handle.net/10398/6699 Files in this item: 1

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.
