Abstract: We propose a novel machine learning technique that can be used to estimate probability distributions for categorical random variables that are equipped with a natural set of classification hierarchies, such as words equipped with word class hierarchies, wordnet hierarchies, and suffix and affix hierarchies. We evaluate the estimator on bigram language modelling with a hierarchy based on word suffixes, using English, Danish, and Finnish data from the Europarl corpus with training sets of up to 1–1.5 million words. The results show that the proposed estimator outperforms modified Kneser-Ney smoothing in terms of perplexity on unseen data. This suggests that important information is hidden in the classification hierarchies that we routinely use in computational linguistics, but that we are unable to utilize this information fully because our current statistical techniques are either based on simple counting models or designed for sample spaces with a distance metric, rather than sample spaces with a non-metric topology given by a classification hierarchy.

Abstract: Kinks and jumps in the payoff function of option contracts prevent an effective implementation of higher-order numerical approximation methods. Moreover, the derivatives (the greeks) are not easily determined around such singularities, even with standard lower-order methods. This paper suggests a transformation to turn the original ill-conditioned pricing problem into a well-behaved numerical problem. For a standard test case, both vanilla- and binary call price functions are approximated with (tensor) B-splines of up to 10’th order. Polynomial convergence rates of orders up to approximately 10 are obtained for prices as well as for first and second order derivatives (delta and gamma). Unlike similar studies, numerical approximation errors are measured both as weighted averages and in the supnorm over a state space including time-to-maturities down to a split second.

Abstract: Housing markets in several countries are suffering. The prolonged and strong housing price rises of recent years have turned around. Historical records suggest that housing price drops may happen slowly but be large. Housing prices continue to fall because capital losses have substituted capital gains, housing equities are falling, and housing price expectations have become negative. Household debt had increased to the same degree as housing prices or even more in some countries. Access to mortgage and credit had improved and lenders used "cruise control” when financing still higher housing market prices. Now, housing demand is further weakened because access to credit has been tightened. During a downturn, owner-occupiers’ housing price risk is increased and a growing number of owners have negative equity and payment troubles. Under these conditions, arrears and foreclosures will be widespread in owner-occupation. The effects on the wider economy of a housing price downturn are discussed. Not only does the lenders’ increased credit risk lead to tightened credit access, losses threaten the banks and can create financial crises. Falling housing prices clearly depress the housing market and housing construction activities and thereby the contribution of residential investments to economic growth, while it is less obvious that average housing consumption and residential investments over the whole cycle are affected. The reduction of non-housing consumption as a result of a wealth effect is a reality for years for depressed owner-occupiers but in the aggregate, the housing wealth effect is more dubious.

Toward an Alternative Epistemology for Gender Research in OrganizationsEllehave, Camilla Funck (København, 2004)[More information][Less information]
Abstract: "How becoming!" we say (though often with a subtle ironic twist) when someone says or does something that we find is suitable or appropriate for him- or her or the situation in which he or she is. And while it may be old-fashioned, the phrase is also used when the clothes people are wearing make them look attractive. By pronouncing: ‘how becoming!’ we condone the appearance, the saying or the doing by making a reference to the appropriateness of somebody’s attire, words and deeds. However, the appropriateness is situated in that it is based on cultural conventions of a particular time and space, and simultaneously produces culturally accepted boundaries around what denotes culturally intelligible identities or subject positions (parallel to suggesting that something is "for the likes of you/us" versus "not for the likes of you/us" (Bourdieu, 1990:55-56)).

A network management perspectiveSundtoft Hald, Kim; Sigurbjornsson, Tomas (Frederiksberg, 2013)[More information][Less information]
Abstract: The aim of this research is to explore the managerial role of category managers in purchasing. A network management perspective is adopted. A case based research methodology is applied, and three category managers managing a diverse set of component and service categories in a global production firm is observed while providing accounts of their progress and results in meetings. We conclude that the network management classification scheme originally developed by Harland and Knight (2001) and Knight and Harland (2005) is a valuable and fertile theoretical framework for the analysis of the role of the category manager in purchasing.

An Examination of Government Policies and Company Initiatives in Denmark and the UKBrown, Dana; Steen Kundsen, Jette (, 2012)[More information][Less information]
Abstract: The literature explains the link between CSR and domestic institutions in terms of the presence of national institutional complementarities as a key determinant of a company’s CSR initiatives. One set of explanations sees CSR as fitting in with domestic institutional structures as either `substituting’ or ‘mirroring’ government policies. A second set of explanations views CSR as driven by variations in competitive needs across countries, reflecting in particular the degree of international market exposure. Both sets of literature look at the level of CSR in companies from different countries. Focusing on the UK and Denmark we study the link between CSR and domestic institutions by examining the content of both government CSR policies and company CSR initiatives. We find that CSR can be a substitute for government regulation, but in contrast to 2 existing literatures we show that this is more likely in the context of host countries rather than in home countries.

A Case Study of Indian FirmsSudhanshu, Rai (Frederiksberg, 2010)[More information][Less information]
Abstract: In this paper I ask the basic question highlighted in the title, how does innovative potential and collaborative capacity contribute to a firm’s innovativeness? To address this central question I draw on innovative potential and collaborative capacity as a dynamic notion evaluates the data from India. This paper tries to create a framework creating a sustainable environment for ICT Innovation. To do that I argue that innovative potential and collaborative capacity provide a constellation of inputs to the firm to address both internal and external challenges. For instance while innovative potential works at a project or an individual level while collaborative capacity is seen to work at a firm or perhaps at the inter firm level. This does not mean IP acts only at the locus stated. I conjecture that IP/CC interact with each other at defferent levels, where each takes turn in driving the process of ICT Innovation.

Abstract: Adopting a survey approach, our study examines how firms implement impairment test of goodwill. We focus on how firms define and measure the recoverable amount of CGU. The survey includes 58 completed questionnaires representing 73% of the firms on the Copenhagen Stock Exchange that recognise goodwill in the balance sheet. Our survey generally supports that a common practice on impairment tests of goodwill has not yet been established. Based on our analysis it is difficult to determine whether this simply reflects that firms adopt an approach suited to their organisational and economic structures or if it exposes that firms are uncertain as how to apply a standard. The analysis also reveals that some of the methods used when defining a CGU are not in compliance with IAS 36. In addition, we find inconsistencies in the way that firms estimate the recoverable amount. Our analysis should be of interest to a number of parties including firms, financial advisors, auditors, standard setters and users of financial statements. Impairment tests, IAS 36, compliance, goodwill, value in use, valuation techniques. URI: http://hdl.handle.net/10398/6744 Files in this item: 1

Abstract: How to motivate knowledge sharing is of crucial importance to many companies. This paper analyzes individual knowledge sharing behavior in a self-determination theory (SDT) perspective. The primary aim is to explore what type of motivation predicts knowledge sharing behavior and how this type of motivation is affected by reward structures and management styles in organizations. The paper builds on survey and interview data from a pilot case study and provides statistical evidence of a strong positive relationship between autonomous motivation and knowledge sharing behavior. Furthermore, tangible rewards are found to correlate negatively with autonomous motivation for knowledge sharing. The more employees perceive knowledge sharing to lead to tangible rewards, the less they are autonomously motivated to share. On the other hand, a management style supportive of employees’ needs for autonomy is found to promote autonomous motivation for knowledge sharing.

Abstract: The IB literature informs us of several ways to measure firms’ degree of internationalization. In this paper we make the argument that in fact none of the existing indices really measure firms’ degree of "global specialization", that is, to what extent their allocation of resources is multidomestic or global. As argued, all the existing measures may gauge a purely multidomestic firm as having a high degree of internationalization, whereas a truly global firm may be ranked low. In order to remedy this we introduce a complementary index measuring how firms are configuring their value chains – whether they are replicating value chain activities from country to country or locating them in globally specialized units in order to exploit an international division of labor. In addition to mathematical modeling and numerical examples, we examine the relevance of the new index of global specialization on data of Danish MNCs by looking at the correlation between the new global specialization index and existing indices of firms’ degree of internationalization. We find that the index is able to identify a distinct group of firms with significantly higher degrees of global value chain configuration. Key words: Internationalization, value chain, global configuration. JEL Codes: F02, F23, L22, L23 URI: http://hdl.handle.net/10398/7480 Files in this item: 1

A longitudinal study of the adoption of online interactive and social media by luxury fashion brandsHansen, Rina (Turku, 2011)[More information][Less information]
Abstract: Most luxury fashion brands have yet to develop a clear and focused integrated online strategy, as they have struggled with the dilemma of interacting with fans and customers online. We observed how 35 luxury fashion brands utilized social and interactive online technologies since 2006 by formulating a framework for assessing fashion websites and brand controlled social media sites. Our findings illustrate that the observed luxury brands have increased their adoption of social and interactive digital technologies since 2006, and that with the help of Web 2.0 technologies fashion brands can create an immersing and innovative environment online.The findings also have relevance for practitioners, as the developed 8C framework can function as a checklist for fashion brand website creation.
