Abstract: Modern hearing aids use a variety of advanced digital signal processing methods in order to improve speech intelligibility. These methods are based on knowledge about the acoustics outside the ear as well as psychoacoustics. We present a novel observation based on the fact that acoustic prominence is not equal to information prominence for time intervals at the syllabic and sub-syllabic levels. The idea is that speech elements with a high degree of information can be robustly identified based on basic acoustic properties. We evaluated the correlation of (information rich) content words in the DanPASS corpus with fundamental frequency (F0) and spectral tilt across four frequency bands. Our results show a correlation of certain band-level differences and the presence of content words. Similarly, but to a lesser extent, a correlation between F0 and the presence of content words was found. The principle described here has the potential to improve the “information-to-noise” ratio in hearing aids. In addition, this concept may also be applicable in automatic speech recognition systems.

Abstract: In this short paper, I put forward an argument about trust based upon an information cost perspective. I argue that, in different contexts, different origins of trust come to dominate. This is so, because different possible origins of trust have a different information cost, and different contexts have different information availability. Agents learn about this, and place their trust accordingly. I provide an empirical example, and list some traits of information availability between geographically proximate firms. The information cost argument explains why a particular way of trusting is prevalent in some proximate ‘communities’ of agents. URI: http://hdl.handle.net/10398/8096 Files in this item: 1

A multi-method inquiry on online communitiesKorfiatis, Nikolaos Theodoros (, 2009)[More information][Less information]
Abstract: This dissertation studies the behavioral characteristics of participants engaged in information exchange in the context of online communities. Online communities are defined as collectives of individuals that use computer mediated communication to facilitate interaction over a shared purpose and/or objective. It is argued that this interaction creates externalities, for example, in the form of codified information that others can use through web search tools. These externalities assemble a virtual form of social capital, a commonly shared resource. The research objective of this thesis is to examine how the behavioral tendencies of the participants in online communities are affected by the way this common resource is formatted, administered and shared. The dissertation consists of two parts: a theoretical part where the empirical background and the object of research inquiry is highlighted, and an empirical part which consists of four empirical studies carried out in the context of three online communities, namely, Google Answers, Yahoo!Answers and Amazon Online Reviews. The empirical part of this dissertation starts with a controlled experiment emulating a well known social dilemma: the public goods game. It provides substance as to whether and when participants in online communities behave (un) cooperatively. The next two studies focus on a special case of online communities where participants ask questions and other participants post answers conditionally on social and monetary incentives. The results of these two studies confirm that community participants do care about the contributions of others and engage in incentive compatible behavior. Yahoo!Answers participants exercise effort in the community by posting answers to questions conditionally on benefits provided by other participants. The empirical findings show that contributing participants in an online community receive answers faster, while those that do not contribute much effort are sanctioned in the form of longer response-time to their questions. In Google Answers this thesis, interactions can be observed that are based on monetary rewards (rather than social rewards in the form of a reputation index as in Yahoo Answers). Participants make use of voluntarily awarded payoffs (tips) along with stated rewards, in order to motivate those that provide answers (answerers) to provide better quality in their responses. The findings of this study confirm the symmetric effect between monetary rewards and quality. However, this study also identifies cases where social norms have a significant effect on response behavior. When participants seek to get better service with less effort (in terms of total cost), a reputation index which is constructed by the history of their previous interactions supports such an attempt. In other words, reputation history influences information sharing behavior in online communities. The last chapter of the empirical part focuses on another crucial aspect of information as a shared resource: Clarity and understandability. The study examines online product reviews on Amazon.com. The results suggest that participants do care about the clarity of this codified form of experience which increases a helpfulness index accordingly. The thesis overall finds symmetric effects between participation in online communities and output of interaction, but also identifies the ability of the participants to interact strategically as they seek to minimize the effort they provide in order to find the information they seek. The results underline the importance of signaling and quality evaluation mechanisms as counter-balancing control that can enhance activity on online communities.

Abstract: In the economics literature, various views on the likely (efficiency) effects of information exchange, communication between firms and market transparency present themselves. Often these views on information flows are highly conflicting. On the one hand, it is argued that increased information dissemination improves firm planning to the benefit of society (including customers) and/or allows potential customers to make the right decisions given their preferences. On the other hand, the literature also suggests that increased information dissemination can have significant coordinating or collusive potential to the benefit of firms but at the expense of society at large (mainly, potential customers). In this chapter, we try to make sense of these views, with the aim of presenting some simple lessons for antitrust practice. In addition, the chapter presents some cases, from both sides of the Atlantic, where informational issues have played a significant role. URI: http://hdl.handle.net/10398/7533 Files in this item: 1

How knowledge workers act as amateurs when using information at workConstantiou, Ioanna; Madsen, Sabine; Papazafeiropoulou, Anastasia (, 2011)[More information][Less information]
Abstract: The proliferation of Internet technologies in the workspace provides tremendous possibilities for knowledge workers to access vast amounts of information from a large number of sources. The information abundance offers new opportunities which empower the knowledge worker but at the same time may create information overload. This study explores academics’ information management practices, by applying a theoretical framework build on three theoretical perspectives. These involve mindfulness, sense-making, and decision-making heuristics. The theoretical framework is used to analyse diary data about three tasks: email management, communication with colleagues, and information search. Our findings show that the knowledge workers have developed their own relatively simple but seemingly suitable practices for dealing with information overload and being empowered from the abundant information available to them. The relative amateurism and professionalism of the participants are discussed and limitations of this study as well as areas for future research are delineated.

- Results from a survey.Moelbjerg Joergensen, Kenneth (København, 1998)[More information][Less information]
Abstract: The aim of this paper is to explore the relationship between organizational change and information technology (IT) in Danish manufacturing and service companies. The data material is a survey covering 1900 Danish companies. In the paper it is shown that there in a three-year period are major correlations between introductions of IT´s and movements towards more integrative organizations. These moves are evident in companies which in the three-year period both have introduced IT and changed their organizations. However in organizations which have introduced IT but reported that they have not changed their organizations, there also seem to be this movement compared to companies which have not done anything. Accordingly moves towards integrative organizations seem to a high degree to go hand in hand with introductions of IT. Three conclusions are deduced from these results. First, that Danish companies apparently have learned the lesson from the mideighties, to think in terms of organization instead of technology when implementing IT. Second, that the word IT apparently comprises powerful technical systems that, when faced, pushes companies towards organizational change. Third I consider if the organizational changes reflect a new learning paradigm or another paradigm labelled reliability. URI: http://hdl.handle.net/10398/8107 Files in this item: 1

Abstract: Business model innovation plays a very important role in developing competitive advantage when multinational small and medium-sized enterprises (SMEs) from developed country enter into emerging markets because of the large contextual distances or gaps between the emerging and developed economies. Many prior researches have shown that the foreign subsidiaries play important role in shaping the overall strategy of the parent company. However, little is known about how subsidiary specifically facilitates business model innovation (BMI) in emerging markets. Adopting the method of comparative and longitudinal case study, we tracked the BMI processes of four SMEs from Denmark operating in China. Using resource-based view (RBV), we develop one theoretical framework which indicates that initiative-taking and improvisational capability of subsidiary are the two primary facilitators of business model innovation in emerging markets. We find that high initiative-taking and strong improvisational capability can accelerate the business model innovation. Our research contributes to the literatures on international and strategic entrepreneurship. URI: http://hdl.handle.net/10398/8814 Files in this item: 1

Abstract: I velfærdsstaten kommunikeres borgerne i roller, som har betydning for deres indoptagelse. Der er hægtet forventninger til rollerne, og borgerne må leve op til bestemte normer og værdier. Nogle brugergrupper forventes aktivt deltagende andre mere afventende. Ofte vil der være vidt forskellige rolleforventninger rettet mod de samme borgere. I nærværende artikel stilles skarpt på de forventninger, der møder de ældre, når de træder ind i velfærdsstaten. Det vises, at to situationer er helt afgørende. Dels er der "det forebyggende hjemmebesøg", som er de ældres første møde med ældreområdet, dels visitationen, hvor der besluttes om de ældres behov. Artiklen diskuterer modsætninger i de to situationers krav til de ældre. På den ene side forstås de ældre som aktive og ansvarliggjorte dialogparter, på den anden side som passive aftagere udsat for benhård behovsvurdering. Optikken for artiklens analyser er systemteoretisk. URI: http://hdl.handle.net/10398/6358 Files in this item: 1

Abstract: The dialectical aspect in the work of George Bataille is often neglected. At the suggestion of Foucault and Derrida, Bataille is most often even taken to be a non-dialectical thinker. But Bataille worked intensely with Hegel's ideas, his thought was expressed in Hegelian terms, and both his epistemology and his ontology can be considered a determinate negation of Hegel’s position in the Phenomenology. This is shown, first, by analyzing Bataille’s notions of ‘inner experience’, and, second, by showing how Bataille extends dialectics to the natural, non-human realm, and even conceives the link between the human and non-human as itself dialectical. However, once we see the dialectical nature of his theoretical stance, we are struck by a great vagueness in his practical conception of where society ought to be going.

Lessons learned from testing a prototype combining talent development and leadership innovation in a Scandinavian hospital settingIngerslev, Karen; Bjørn, Kasper; Johansen, Jørgen (, 2012)[More information][Less information]
Abstract: This paper addresses the potential clash between the “non-failure” culture of the hospital and the “fail-fast-forward” approach of innovation by sharing and analysing narratives from a field study of innovation processes. The case is a large university hospital in Scandinavia and the health care sector in general is outlined as context of the challenges addressed by the innovation processes. The narratives fall into three overlapping categories; the product, the process and the culture of innovation. Regarding the product of innovation, we outline the lessons learned about tensions created by ambitions of radical innovation in a public sector context, challenged by the idea of small-scale experiments and the participant’s feelings of inferiority. As for the process of innovation: we share the lessons learned about how linear and non-linear thinking affects the process of innovation. Addressing the culture of innovation, we discuss the lessons learned from working with a prototype testing approach in a system characterized by an evidence-based non-failure culture. Finally we summarize the lessons learned and share concluding perspectives. URI: http://hdl.handle.net/10398/8647 Files in this item: 1

Abstract: This article studies the theoretical and applied development of the creative economy. There exists many definitions of creative industries, creative economy and experience economy, all dealing with the same core problematic. It is why it is chosen in this article to talk about the creative economy complex. The ideas to the different elements in the complex have been developed over the last 20 years. A conclusion on experience economy and creative industries is presented on page 7. It is followed by a presentation of how the creative economy complex has been applied in the Baltic Sea Countries and by a section on the development of the creative economy complex after the financial crisis in 2008. It is found that the complex and its development has been closely related to the business cycle development, implying that the complex from being a general theory in times with positive business cycle development has changed to become more specific and integrated into marketing, regional economy and innovation theory when the business cycle changes to recession and when state debt becomes a main economic problem.

A potential for local business development?Tetzschner, Helge; Herlau, Henrik (København, 2003)[More information][Less information]
Abstract: Over the past few years, the tourist industry has come to be recognised as a way of providing strategic support for sustainable local business development. In this article we attempt to define an appropriate innovation concept in relation to tourism on the basis of an attractor principle. We then discuss the concept of entrepreneurship in connection with tourism, looking at its significance in its relationship with local business development, thereby positing the premise of social entrepreneurship. This frame of reference is used in five cases in the analysis. The analysis shows that it is possible to innovate and draw up plans for new attractors but that it is considerably more difficult to convert these plans into reality through social entrepreneurship. The conclusion is that we need to focus upon organisation of semi-public tourist organisations, if we want tourism to promote local business development.

A Case Study of the Laundry Detergent Market in JapanFujiwara, Masatoshi (Frederiksberg, 2011)[More information][Less information]
Abstract: This paper aims to describe how a commercially successful innovation occurs with the altering of the existing competitive structure in a market under environmental and competitive pressures. I study the history of the laundry detergent market in Japan and elucidate the manner in which Kao accomplished an innovation and increased their market share during the late 1980s. Kao introduced their new detergent Attack through a biotechnological innovation and dramatically changed the competitive structure to their advantage. The innovations introduced were of two kinds 1) fermentation engineering technologies to improve the cleaning performance of detergents by using alkaline cellulase, and 2) concentration of detergents to four times their earlier strength through changes in their powder processing technologies. This historical innovation that occurred in the laundry detergent market in Japan has a contemporary implication because combining firms’ activities and environmental sustainability has been one of the most crucial topics over recent years.

Abstract: An earlier version of this paper was prepared for the joint OECD/Eurostat workshop on innovation surveys, OECD, Paris, June 30th 1999. The paper addresses some issues about the nature of innovation surveys (particularly the new Community Innovation Surveys) and how they might be improved to take on board several crucial developments in contemporary advanced economies. In particular the following topics are discussed: the increased distribution of innovative activity across firms and networks; the problems of service sector innovation and the comparability of services and manufacturing firms; and the problems of labour in the innovation process.

The Case of the Executive Master of Public Governance Program in Copenhagen, Denmark: A co-operation between University of Copenhagen and Copenhagen Business SchoolGreve, Carsten (Frederiksberg, 2011)[More information][Less information]
Abstract: This paper gives an introduction to the Executive Master of Public Governance degree program in Copenhagen, Denmark – a joint effort by University of Copenhagen and Copenhagen Business School aided by Aalborg University. The degree program itself began its first intake of executive students in August 2009. The average age of participants is 45 years. By the summer of 2011, the Copenhagen MPG program had enrolled 500+ public managers from Denmark as executive master students. In order to understand the context of the program, the paper gives an introduction to the background of the establishment of the program which was a result of a government reform – the Quality Reform – agreed and also funded partly by the Danish Parliament in 2008. The second part of the paper describes the organization and purpose of the program. The third part presents the content of the degree program. The paper ends by pointing to some preliminary lessons learned and future directions for the program. URI: http://hdl.handle.net/10398/8571 Files in this item: 1
