Abstract: (1) The essence of Yin-Yang is that yin and yang are contrary yet complementary. 阴阳的本质是阴阳是相生相克的关系。 (2) This contrary yet complementary relationship can be described by three characteristics of Yin-Yang: nonexclusivability, transformability, and coopetitionability. Nonexclusivability means that anything contains yin and yang elements and neither yin nor yang elements can be excluded because within both elements there is a seed of the opposite element. Due to the existence of a seed of the opposite element, the yin and yang elements can be mutually transformed when the opposite seed grow to a certain size. Due to this possible growth of the inside opposite element, the relationship between yin and yang and their inside opposite element is one of competition and cooperation, i.e. coopetition. When the configuration ratio of an element’s opposite seed is within the range of 1% to 25%1, their relationship is more co-operative than competitive, and therefore there is more synergy than tradeoff between them. The closer the ratio is to 25%, the stronger the synergy. When the ratio is within the range of 25% to 49%, their relationship is more competitive than cooperative, and therefore there is more tradeoff than synergy between them. The closer the ratio is to 49%, the stronger the tradeoff. 阴阳的相生相克关系可以描述为三个特性：不可排除性、相互转化性、竞 争合作性。不可排除性是指任何事物都包含阴阳两个对立元素，二者之任 何一个均不可能被排除在我，这是因为在阴或阳元素内部天然的包含着对 立元素的种子。正是因为这个种子的天然存在，阴和阳元素可以互相转 化，这种转化发生在对立元素种子成长到一定程度的时候。正是由于这种 对立元素的成长可能性，阴或阳元素和它内部的对立元素之间的关系是既 竞争又合作的。当内部的对立元素占总体元素的力量比例在1%到25%之 间时，两者的关系是合作多于竞争，越靠近25%这个点，这种合作的协同 效果也强烈。当这个搭配比例处于25%到49%之间时，它们的关系将是 竞争多于合作，也就是他们更多互相排斥而非互相促进。当这个比例越靠 近49%，这种排斥效应越强烈。 URI: http://hdl.handle.net/10398/8891 Files in this item: 1

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: Abstract We analyze firms’ incentives to cluster in an industrial district to benefit from reciprocal technology spillovers. A simple model of cumulative innovation is presented where technology spillovers arise endogenously through labor mobility. It is shown that firms’ incentives to cluster are the strongest when the following three conditions are met: 1) technological progress is rapid; 2) competition in the product market is relatively soft; 3) the probability of a single firm to develop an innovation is neither very high nor very low. We show that some trade secret protection is always beneficial for firms’ profits and stimulates clustering. Excessive protection may impede technology spillovers and reduce firms’ incentives to cluster. JEL Codes: J3, K2, L1, O32, O34.

Accentuated challenges of IT & Operations-based value creationToppenberg, Gustav (Frederiksberg, 2013)[More information][Less information]
Abstract: Technology driven industries have seen fast moving technology changes, higher complexity and reduced product life cycles. These emerging trends present challenges for companies in industries where technology is at the forefront. The extant research deals with ‘low-tech’ industries and majority of findings are not applicable to the high-tech industry; in fact this industry has many additional challenges. In this study, we aim to explore the process of M&A in the high-tech industry by drawing on extant literature and empirical field work. The paper outlines a research project in progress which intends to provide theoretical, empirical and practical contributions in answering the research question: what role does Operations and IT play in creating value in high-tech M&As? The research adds a needed perspective on M&A literature by unveiling unique challenges and opportunities faced by the M&A teams in this sector. The phenomenon is studied from multiple perspectives: integration team, acquiring group and the company being acquired. URI: http://hdl.handle.net/10398/8787 Files in this item: 1

Er Danskere Specielle?Munch, Jakob Roland; Rose Skaksen, Jan; Schroll, Sanne; Malchow-Møller, Nikolaj (København, 2006)[More information][Less information]
Abstract: Denne artikel belyser holdninger til immigration blandt borgere i Danmark og de øvrige EU-15 lande - herunder holdningerne til immigration, der følger af den seneste EU-udvidelse. Det analyseres, hvilke faktorer der ligger til frund for disse holdninger, samt i hvilken udstrækning danskere afviger fra EU-gennemsnittet. Den typiske dansker er lidt mere skeptisk overfor immigration end andre europæere. Danskerne afskiller sig desuden ved, at forholdsvis få forbinder øget immigration med negative konsekvenser for arbejdsmarkedet, men forholdsvis mange forbinder det med højere omkostninger for velfærdsstaten. Når der tages hensyn til opfattelserne af de økonomiske konsekvenser af immigration, kommer Danmark til at fremstå som et væsentligt mere immigrationsskeptisk land, end hvad der kommer til udtryk i de ukorrigerede holdninger.

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.

Abstract: The paper develops theory to propose how considering digital information good characteristics modify and extends existing explanations with regard to entry mode choices (in single markets) and internationalization paths (across countries). Explanations offered relate to network and lock-in effects, complementary infrastructure investments, branding, and customer learning – factors that are particular important for understanding international market entry of digital information good providers.
