Abstract: Digital 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. This paper investigates the recent observation that speech elements with a high degree of information can be robustly identified based on basic acoustic properties, i.e., function words have greater spectral tilt than content words for each of the 18 Danish talkers investigated. In this paper we examine these spectral tilt differences as a function of time based on a speech material six times the duration of previous investigations. Our results show that the correlation of spectral tilt with information content is relatively constant across time, even if averaged across talkers. This indicates that it is possible to devise a robust method for estimating information density in the speech signal based on computationally simple short-term band-level differences. The principle described here has the potential to improve speech transduction in hearing aids and cochlear implants. In addition, the concept of information-based speech transduction may also be applicable in automatic speech recognition systems. URI: http://hdl.handle.net/10398/8617 Files in this item: 1

Abstract: Hvordan kan man forklare, at små, nystartede, ressourcesvage virksomheder er i stand til at udfordre og sommetider udkonkurrere store, markedsledende foretagender – ofte med utroligt enkle virkemidler? Som er i stand til at ændre spillets regler på trods af intens konkurrence og høje adgangsbarrierer. Praksis viser, at teknologiske opdagelser, produktmæssig nyskabelse, speciel heldig timing eller særlig passivitet fra konkurrenters side langtfra altid er forklaring nok. Der må med andre ord eksistere en unik innovationsform eller -formel, der kan føre til konkurrencefordele ad helt andre veje! Dette paper præsenterer og diskuterer en sådan anden opfattelse af innovation og viden med fokus på den virksomhed eller iværksætter, som ikke har andet at ty til end idérigdom. Som er nødt til at bryde med spillets regler og betræde helt nye stier for at kunne konkurrere. Det har jeg kaldt strategisk innovation. Konklusionen er, at strategisk innovation frembringes af særlige kompetencer. Kompetencer, som den lille, ressourcemæssigt underlegne virksomhed eller outsideren har mindst lige så store chancer for at beherske som etablerede spillere i markedet. Nøglen til strategisk innovation er kreativ markedsviden omsat til ny, overraskende forretningslogik! URI: http://hdl.handle.net/10398/6303 Files in this item: 1

A Meta AnalysisMeyer, Klaus E.; Sinani, Evis (København, 2005)[More information][Less information]
Abstract: The extensive empirical literature analyzing productivity spillovers from foreign direct investment to local firms provides inconclusive results. Some studies find that foreign presence has a positive impact on the productivity of domestic firms, while others find no evidence or a negative effect. Differences in the results may be attributable to contexts, such as the structural differences between developed, developing and transition economies. However, results may also vary due to different empirical methodologies, notably the use of aggregate versus firm-level data and cross-section versus panel data analysis. We conduct a meta-analysis to investigate reasons for these conflicting results, and provide a revised interpretation of earlier research and its policy implications, and new priorities for future research. Our analysis suggests that the hypothesized spillovers are not confirmed for industrialized countries in the 1990s. Transition economies may experience spillovers, but these have been declining in recent years.

En rapport fra implementering af Sprogkernen I’s anbefalingerLenstrup, Christine; Faizi, A. Zaki; Pals Svendsen, Lisbet; Mondahl, Margrethe (, 2012)[More information][Less information]
Abstract: Formålet med denne rapport er at undersøge i hvilket omfang IKT skaber motivation, interaktion, samarbejde og refleksion i forbindelse med tilegnelsen af interkulturel handlingskompetence. Vores hypotese er, at anvendelsen af forskellige former for IKT i undervisningen kan være med til at øge elevernes motivation og arbejdsindsats og derigennem også deres udbytte af undervisningen, således at eleverne opnår en højere grad af deep learning end uden IKT. For at eftervise vores hypotese, gennemførte vi i efteråret og vinteren 2011/2012 kvalitative empiriske undersøgelser i samarbejde med to udvalgte gymnasieskoler. Mere præcist udførte vi fokusgruppeinterviews med elever og lærere. Efter at have analyseret vores data, kom vi frem til nogle resultater, hvoraf nogle er positive og andre mindre positive: • IKT skaber motivation • IKT har en positiv effekt på interaktion og samarbejde • IKT fremmer elevernes evne til at reflektere over egen læring Men: • IKT fører ikke nødvendigvis til internalisering af viden • IKT kan opfattes som useriøst og irrelevant i en læringssammenhæng Baseret på ovennævnte resultater, når vi frem til følgende 4 anbefalinger: • IKT skal italesættes i langt højere grad end hidtil og bør være tydeligt defineret som en løftestang i læringskonteksten • IKT skal italesættes systematisk, således at det er et relevant læringsværktøj • IKT muliggør etablering af sociale kontekster, som kan etablere interaktion med andre sprogbrugere, og bør derfor tilpasses den didaktiske kontekst og eksponere eleverne mindre end traditionel klasseundervisning. • IKT-‐anvendelse bør evalueres løbende i forhold til fagrelevans og læringsmål URI: http://hdl.handle.net/10398/8638 Files in this item: 1

Business Relationship Resroration After Severe Norm Violation Episodes.Houman Andersen, Poul; Ellegaard, Chris (Frederiksberg, 2010)[More information][Less information]
Abstract: Relational norms provide behavioural guidelines for individual actors interacting in business relationships. Frequently, norms are violated and the involved actors initiate a normalization process to restore exchange order. However, in rare instances violations occur with a severity where the exchange cannot be normalized by the means available in the interpersonal relationship. Furthermore, dissolution is not an option due to high perceived dependence. In this paper, we report on an investigation of three such severe norm violation episodes. We identify the violated norm sets and violating behaviours of core actors along with emotional reactions and effects on the business exchange. In addition, we map the processes of violation and normalization. We find evidence of serial norm violations, causing the interpersonal relationship to enter a state of suspension. Furthermore, cross case analysis shows that exchange was normalised through an organizational level process of alternative actor channel activation and executive intervention.

The role of the state in the development and reproduction of "the Danish model”Kaspersen, Lars Bo; Schmidt-Hansen, Ulrich (København, 2006)[More information][Less information]
Abstract: In the literature on the establishment and development of the Danish variant of corporatism, emphasis has most often been on the role of the social partners. Scholars rarely stress the crucial role which the state has played in the development of the system. We argue that several actors contributed to the development of the ‘Danish model’, but that these actors were often orchestrated by the state. At crucial moments the direction of these different actors was even determined by the state. In the first part of the article, it is argued that the state has been under-theorized and to some extent neglected in corporatist theory. In particular, we draw upon a conceptualization of the state developed by Michael Mann and Eric Nordlinger’s different forms of state autonomy. We propose a state-centered theoretical focus enabling us to grasp the role of the state in the dynamics of the corporatist system. In the second part of the article, we present an analysis of the establishment and evolution of the Danish corporatist system seen from this distinctively state-centered perspective. In the third part we look into the current system during the last decade of the 20th century. By newly- conducted empirical research, we examine the role of the state in the corporatist system during the 1990s in the labour market and within immigration integration policy. We conclude that due to its autonomous power, the state is still a key player in the corporatist system. URI: http://hdl.handle.net/10398/7362 Files in this item: 1

Abstract: Purpose: We have examined which dimensions are used by the largest Danish manufacturing companies to measure SCPM at operational, tactical and strategic level, how can these dimensions be classified, and how do these empirical results have implications for practice and selected SCPM-theories. Design/methodology/approach: A deductive structure based on a theoretical framework was used to design an empirical investigation of 54 Danish manufacturing companies, which all have revenue of more than DKK 500 million. Furthermore, qualitative investigation was done by analyzing four casecompanies in order to get a more in-depth picture of how SCPM is used in practice. Findings: The four most used SCPM metrics have downstream focus. Companies that use SCPM have a more deliberated split between metrics with focus on operational, tactical and strategic level. While the quantitative data indicates that non-financial measurements are most frequently used, the qualitative data implies that the companies use financial measures as basis for performance measurement and that results from non-financial measures have second priority. Research limitations/implications (if applicable): The model is limited to large Danish industrial companies and we propose to widen the model to upstream and downstream supply chain partners. Practical implications (if applicable): The paper shows the most important and most frequently used supply chain relevant key performance indicators as well as a process model of how to implement supply chain performance measurement in a company. Original/value: This paper closes the gap between theory and practice within the area of performance measurement and management within the context of supply chain management. The proposed SCPM model has been theoretically developed and empirically validated. URI: http://hdl.handle.net/10398/8331 Files in this item: 1

Abstract: For blot 15 år siden var det ved at blive en veletableret kendsgerning, at den suveræne stat eller den nationale stat var blevet ”svækket”, ”udhulet”, eller på anden vis ændret i retning af at blive en mindre vigtig faktor i organiseringen af sociale, økonomiske og politiske – nationale såvel som internationale - relationer. Den australske politolog Linda Weiss kritiserede denne trend og kaldte den for ”The State Denial”1. Hun henviste til en lang tradition for at trivialisere statens samfundsmæssige rolle indenfor samfundsvidenskaberne, men fremhævede også, hvordan trivialiseringen i 80`erne og 90`erne skabte en udbredt skepsis over for, at de nationale stater havde ressourcer og handlerum til at modstå kapitalstrømmenes globalisering og politikkens europæisering.

evalueringsrapport over Master of Public AdministrationRy Nielsen, Jens Carl (København, 2003)[More information][Less information]
Abstract: Med denne rapport ønsker vi at gøre status over de første 9 år med uddannelsen til Master of Public Administration (MPA) ved Handelshøjskolen i København. Grundlaget for rapporten er en selvevaluering, der i 2002 blev udarbejdet til den første officielle evaluering af masteruddannelser i Danmark. Danmarks Evalueringsinstitut under Undervisningsministeriet gennemførte her en evaluering af MPA-uddannelsen samt uddannelsen til Master of Public Management (MPM) ved Syddansk Universitet og uddannelsen til Master of Public Policy (MPP) ved Roskilde Universitetscenter. Resultatet af evalueringen er fremlagt i en samlet rapport: "Masteruddannelser" fra september 2003. Den eksterne evaluering giver MPA-uddannelsen en særdeles positiv vurdering, men indeholder også konstruktiv kritik. Generelt er studieledelsen og lærergruppen naturligvis meget glade for evalueringen, som til fulde bekræfter, at MPA-uddannelsen er et godt produkt, der har bevist sin berettigelse de seneste 9 år. I rapporten fra Danmarks Evalueringsinstitut indgår der naturligvis mange elementer fra MPA’s selvevalueringsrapport, men studieledelsen på MPA har skønnet, at en forkortet og revideret udgave af denne rapport kunne være nyttig i forbindelse med information om MPA-uddannelsen til ansøgere, aftagere, nye undervisere, rådgivere og andre interesserede. Denne reviderede rapport udgør derfor et vigtigt vidnesbyrd om grundlaget for og de løbende justeringer af uddannelsen. Rapporten indgår samtidig som et afgørende grundlag for det udviklingsarbejde, der i 2003 er sat i gang med henblik på at på at revidere og præcisere MPA-uddannelsens kompetenceprofil og herved fremtidssikre et godt produkt. J.C. Ry Nielsen, der er en af grundlæggerne af uddannelsen og i dag vicestudieleder for den internationale del, har på studieledelsens foranledning bearbejdet selvevalueringsrapporten til den her foreliggende udgave.

Abstract: This paper introduces the concept of a steepest ascent tariff reform for a small open economy. By construction, it is locally optimal in that it yields the highest gain in utility of any feasible tariff reform vector of the same length. Accordingly, it provides a convenient benchmark for the evaluation of the welfare effectiveness of other well known tariff reform rules, as e.g. the proportional and the concertina rules. We develop the properties of this tariff reform, characterize the sources of the potential welfare gains from tariff reform, use it to establish conditions under which some existing reforms are locally optimal, provide geometric illustrations and compare welfare effectiveness of reforms using numerical examples. Moreover, being a general concept, we apply it to the issue of market access and examine its implications. Overall, the paper’s contribution lies in presenting a theoretical concept where the focus is upon the size of welfare gains accruing from tariff reforms rather than simply with the direction of welfare effects that has been the concern of the literature.

Abstract: In his influential essay on markets, An essay on framing and overflowing (1998), Michel Callon writes that "the growing complexity of industrialized societies [is] due in large part to the movements of the technosciences, which are causing connections and interdependencies to proliferate". This paper is about tech-noscience, and about the proliferation of connections and interdependencies created by it. More specifically, the paper is about stem cells. Biotechnology in general has the power to capture the imagination. Within the field of biotechnology nothing seems more provocative and tantalizing than stem cells, in research, in medicine, or as products. URI: http://hdl.handle.net/10398/6727 Files in this item: 1

Abstract: This paper examines the macroeconomic effects of youth unemployment programmes in the form of vocational training (YUPs), developing a two sector general equilibrium model featuring matching frictions and worker-fi rm wage bargaining for skilled workers. Unskilled sector wages are indexed to skilled sector wages. Workers differ with respect to ability, having importance for the young worker s skill decision. Furthermore, a young worker may be offered vocational training through YUPs. The total number of skilled workers is therefore determined by these two channels and the interaction between them. We focus on the impact of of YUPs on skill division, unemployment distribution workers and aggregate unemployment.

Abstract: This paper presents stories from fieldwork among parking patrol officers and managers in a Danish municipal centre. The stories are about the hiring, firing and retention of parking officers. The centre is renowned for management’s active and ambitious work to improve the work environment for parking patrol officers, the quality of parking services and to employ diversity management. As many other types of unskilled work in Denmark, the job as parking patrol officer is a possible entry point to the labour market for people without formal education or people who have been worn out in other occupations. By presenting stories told by parking patrol officers and their managers at Centre for Parking, I wish to contribute to our understanding of the role of the public sector as an employer: the ambitions and limits of the public sector in regard to employing people for unskilled work and the dilemmas that follow. The aim of the paper is to show how these stories shape the simultaneous processes of professionalizing the traditionally unskilled work of parking patrolling and fulfilling a role as a socially inclusive workplace.
