Abstract: Recent research in the field of computational social science have shown how data resulting from the widespread adoption and use of social media channels such as twitter can be used to predict outcomes such as movie revenues, election winners, localized moods, and epidemic outbreaks. Underlying assumptions for this research stream on predictive analytics are that social media actions such as tweeting, liking, commenting and rating are proxies for user/consumer’s attention to a particular object/product and that the shared digital artefact that is persistent can create social influence. In this paper, we demonstrate how social media data from twitter can be used to predict the sales of iPhones. Based on a conceptual model of social data consisting of social graph (actors, actions, activities, and artefacts) and social text (topics, keywords, pronouns, and sentiments), we develop and evaluate a linear regression model that transforms iPhone tweets into a prediction of the quarterly iPhone sales with an average error close to the established prediction models from investment banks. This strong correlation between iPhone tweets and iPhone sales becomes marginally stronger after incorporating sentiments of tweets. We discuss the findings and conclude with implications for predictive analytics with big social data. URI: http://hdl.handle.net/10398/8985 Files in this item: 1

Abstract: The purpose of the current investigation is to predict post-editor profiles based on user be- haviour and demographics using machine learning techniques to gain a better understanding of post-editor styles. Our study extracts process unit features from the CasMaCat LS14 database from the CRITT Translation Process Research Database (TPR-DB). The analysis has two main research goals: We create n-gram models based on user activity and part-of-speech sequences to automatically cluster post-editors, and we use discriminative classifier models to character- ize post-editors based on a diverse range of translation process features. The classification and clustering of participants resulting from our study suggest this type of exploration could be used as a tool to develop new translation tool features or customization possibilities.

A Machine Learning ApproachSaikh, Tanik; Bangalore, Srinivas; Carl, Michael; Bandyopadhyay, Sivaji (, 2015)[More information][Less information]
Abstract: In this paper an attempt has been made to predict the gaze fixation duration at source text using supervised learning techniques. The machine learning models used in the present work make use of lexical, syntactic and semantic information for predicting the gaze fixation duration. Different features are extracted from the data and models are built by combining the features. Our best set up achieves close to 50% classification accuracy.

Abstract: Sustainable work behavior is an important issue for operations managers – it has implications for most outcomes of OM. This research explores the antecedents of sustainable work behavior. It revisits and extends the sociotechnical model developed by Brown et al. (2000) on predicting safe behavior. Employee characteristics and general attitudes towards safety and work condition are included in the extended model. A survey was handed out to 654 employees in Chinese factories. This research contributes by demonstrating how employee- characteristics and general attitudes towards safety and work condition influence their sustainable work behavior. A new definition of sustainable work behavior is proposed. URI: http://hdl.handle.net/10398/8775 Files in this item: 1

Abstract: This paper expands entry mode literature by referring to multiple modes exerted in different value chain activities within and across host markets, rather than to a single entry mode at the host market level. Scale of operations and knowledge intensity are argued to affect firms’ entry mode diversity across value chain activities and host markets. Analyzing a sample of Israeli based firms we show that larger firms exhibit a higher degree of entry mode diversity both across value chain activities and across host markets. Higher levels of knowledge intensity are also associated with more diversity in firms’ entry modes across both dimensions. URI: http://hdl.handle.net/10398/7445 Files in this item: 1

The Sensing of Frontline Employees Against Executive ExpectationsHallin, Carina Antonia; Andersen, Torben J.; Tveterås, Sigbjørn (Frederiksberg, 2012)[More information][Less information]
Abstract: The literature suggests that important strategic initiatives can derive from employees within the organization as they respond to needs and opportunities observed in daily operations. This seems to indicate that employees have a good sense of the firm’s operational capabilities observed through direct interactions with colleagues, customers and partners. Executives make their own judgments about the corporate capabilities from discussions with various managers, other executives and industry specialists. But, the information gathered by executives may be qualitatively different from the conditions sensed by the employees. So, we arranged a contest between operational capabilities assessed by employees and executives and the relationship to subsequent firm performance. Based on more than 400 individual data points collected from two medium-sized organizations over a period of eighteen months, advanced distributed lag time-series analyses show that the sensing of front-line employees (surprisingly) is a better medium-term predictor of organizational performance than executive judgments. These results have implications for the way organizations set up their management information and communication structure. URI: http://hdl.handle.net/10398/8471 Files in this item: 1

Based on a conceptual model of social data consisting of social graph (actors, actions, activities, and artefacts) and social text (topics, keywords, pronouns, and sentiments), we develop and evaluate linear regression models that transform (a) iPhone tweets into a prediction of the quarterly iPhone sales with an average error close to the established prediction models from investment banks (Lassen, Madsen, & Vatrapu, 2014)and (b) facebook likes into a prediction of the global revenue of the fast fashion company, H&M.

Abstract: The standard of proof in criminal law a®ects retributive justice through the number of wrong convictions and wrong acquittals. It also a®ects the level of crime, since a higher standard of proof implies less deterrence and less incapacitation. This article derives an expression for the optimal standard from a trade-o® between these e®ects, and applies the expression to the crime of sexual violation against women. For this crime, social preferences for justice versus prevention of crime are elicited through a survey and inserted into the expression for the optimal standard. The result indicates that the concern for prevention of crime may have a signi¯cant e®ect on the optimal standard of proof. URI: http://hdl.handle.net/10398/6785 Files in this item: 1

Abstract: Price-earnings ratios are part of the toolkit that is used for assessing the valuation of individual firms on the stock market as well as the entire market itself. This paper presents consistent P/E series for the liquid Danish shares adjusted for share buybacks. The results show that over the period from 1969 to 2003, the average (trailing) P/E equals 13.5. The P/E reaches its lowest level in 1980, which is likely to be due to a soaring oil price, high wage increases and interest rates approaching 20 percent. Notwithstanding optimistic equity pricing also in Denmark in the late 1990s, the upturn in Danish valuations was more moderate than in the US. The correction that sets in subsequently reversed essentially the gains in the Danish P/E in the 1990s. URI: http://hdl.handle.net/10398/7620 Files in this item: 1

Boom, Anette (Frederiksberg, 2015)[More information][Less information]
Abstract: Inspired by recent regulations in the New York ICAP market, this paper examines the e ect of price regulations on a multi-unit uniform price auction. General bid caps reduce the maximum price below the bid cap, but also the minimum potential market price below the cap. A bid cap only for the larger rms does not guarantee a market price below the cap. A su ciently high bid oor only for relatively small rms destroys some or all pure strategy equilibria with equilibrium prices above the marginal costs. With a general bid oor this happens only with considerably larger bid oors. URI: http://hdl.handle.net/10398/9245 Files in this item: 1

The Role of Mentalizing for Reward Design and Managenemt in Principal-Agent RelationsFoss, Nicolai J.; Stea, Diego (Frederiksberg, 2013)[More information][Less information]
Abstract: Agency theory is one of the most important foundational theories in management research, but it rests on tenuous cognitive assumptions. We combine classical agency theory with a realistic theory of the intrinsically imperfect human potential for interpersonal sensemaking. This allows us to systematically show how the principal’s ability to mentalize with the agent influences value creation in principal-agent relations, and to link this to organizational sensemaking instruments.

Separating the Impact of Dual Class Shares, Pyramids and Cross-ownership on Firm Value Across Legal Regimes in Western EuropeBennedsen, Morten; Meisner Nielsen, Kasper (København, 2005)[More information][Less information]
Abstract: Recent policy initiatives within the harmonization of European company laws have promoted a so-called "principle of proportionality" through proposals that regulate mechanisms opposing a proportional distribution of ownership and control. We scrutinize the foundation for these initiatives by analyzing the use of instruments to separate ownership from control across legal regimes in a sample of over 4,000 publicly traded firms from 14 Western European countries. First, we confirm the negative impact on firm value from disproportional ownership structures previously established in a sample of Asian firms by Claessens et al. (2002). Second, we show that dual class shares have a larger and more significant negative effect on firm value than pyramids and cross holdings. Third, we find that the impact of disproportionality and the underlying instruments is inversely related to the level of investor protection. Thus, dual class shares and pyramids substitute legal protection in countries with inadequate investor protection. Fourth, we find no evidence of a significant effect of disproportionality instruments on earnings performance. Finally, we discuss policy implications of these findings in relationship to the process of harmonization of the European capital markets.

Abstract: These lecture notes present the basic principles of phrase structure that apply in English. We start by presenting in some detail the most complex phrase type in English, the noun phrase. Having done that, we demonstrate that all the other main phrase types, the AP, the PP and the VP, are modelled on the same structural principles as noun phrases.

Reflecting and Reinforcing Neo-Liberal GovernmentalityLeander, Anna (København, 2006)[More information][Less information]
Abstract: This article argues that the role of Private Security Contractors in Darfur reflects and reinforces neo-liberal governmentality in contemporary security governance. It is an argument (in line with other articles in this special issue) which is more interested in discussing how the privatization of security alters security practices (including those involving states) than in thinking about their impact on an idealised public monopoly on the use of force. To make its point, the article begins by drawing on Foucauldian work to clarify the meaning of neo-liberal governmentality in security. It underlines that governance is increasingly taking place through a set of (quasi-) markets, it is marked by entrepreneurial values, and a hands off approach to governance. We then discuss the way this overall change is reflected in and reinforced by the role of private security contractors in Darfur. Drawing on a framework of analysis inspired by Bourdieu, we show that neo-liberal governmentality is reflected in the dispositions of security actors as well as in their relative positions. The resulting security practices reinforce dispositions and positions that reproduce neo-liberal governmentality. Looking at these processes is necessary to understand the role of private security contractors in Darfur. But more than this, practices in Darfur entrench neo-liberal governmentality in security more generally. The managerial and ‘de-politicizing’ approach to security in Darfur displaces alternative views not only in the Darfuri context. It is taken into other contexts where it bolsters neo-liberal governmentality. This spiralling neo-liberal governmentality rather than diminished state control and authority is, we argue, the most significant consequence of the presence of private security contractors in Darfur.

The Emergence of Stakeholder CapitalismMeyer, Klaus E. (København, 2003)[More information][Less information]
Abstract: An unintended outcome of transition is the emergence of new forms of governance. Stakeholders other than shareholders influence corporate management to a higher degree than in mature market economies. Employees gained influence through ownership stakes or work councils, while elsewhere investment funds or governmental authorities retain influence via equity stakes or otherwise. This paper reviews privatisation and the newly created forms of private ownership to document the evolution of stakeholder capitalism and to discuss the opportunities and dangers that it may create for businesses in the region.
