T1 - A competence portfolio for professionals in the creative industries
JF - Creativity and innovation management
N2 - Within the last decade, the role of the Creative Industries has grown to become an important part of the economic system. The increasing acceleration of new developments in media and ICT technologies greatly affected the Creative Industries' dynamic with a direct impact on the people working in this sector. Since only a few studies focus on competences needs, more or less isolated from the trends within the industry, we address the topic of individual competence shifts in the turbulent environment of the Creative Industries. We investigated the trends regarding competence shifts and their implications as well as the competences which are essential for creative professionals. We conducted a broad literature review as well as a qualitative study, which includes interviews and workshops with industry experts on trends within the Creative Industries and corresponding dimensions and demands for competences. We present four requirements that call for shifts in the education of competences. Based on the discussion of requirements, we present a competence portfolio for the Creative Industries along the dimensions of professional, methodological and personal-social competences. The portfolio clearly indicates which competences should be taken into consideration for the development of curricula and study programmes in the education of creative professionals. A generalization of these findings suggests new challenges for companies relying on creative professionals.

T1 - A conceptual model of knowledge dynamics in the industry 4.0 smart grid scenario
JF - Knowledge management research & practice : KMRP
N2 - Technological advancements are giving rise to the fourth industrial revolution - Industry 4.0 -characterized by the mass employment of smart objects in highly reconfigurable and thoroughly connected industrialproduct-service systems. The purpose of this paper is to propose a theory-based knowledgedynamics model in the smart grid scenario that would provide a holistic view on the knowledge-based interactions among smart objects, humans, and other actors as an underlyingmechanism of value co-creation in Industry 4.0. A multi-loop and three-layer - physical, virtual, and interface - model of knowledge dynamics is developedby building on the concept of ba - an enabling space for interactions and theemergence of knowledge. The model depicts how big data analytics are just one component inunlocking the value of big data, whereas the tacit engagement of humans-in-the-loop - theirsense-making and decision-making - is needed for insights to be evoked fromanalytics reports and customer needs to be met.

T1 - A decision maxim for efficient task realization within analytical network infrastructures
JF - Decision support systems : DSS ; the international journal
N2 - Faced with the increasing needs of companies, optimal dimensioning of IT hardware is becoming challenging for decision makers. In terms of analytical infrastructures, a highly evolutionary environment causes volatile, time dependent workloads in its components, and intelligent, flexible task distribution between local systems and cloud services is attractive. With the aim of developing a flexible and efficient design for analytical infrastructures, this paper proposes a flexible architecture model, which allocates tasks following a machine-specific decision heuristic. A simulation benchmarks this system with existing strategies and identifies the new decision maxim as superior in a first scenario-based simulation.

T1 - A distributional analysis of recent reform proposals on the german income tax rate
JF - Jahrbücher für Nationalökonomie und Statistik = Journal of economics and statistics
N2 - The present paper investigates potential fiscal and distributional effects which emerge due to four reform scenarios on the German income tax rate. The analysis is based on a static simulation model for the German tax system using income tax micro-data. The data shows that changing the present progressive tax system to a flat-tax, which was proposed by the FDP in 2010, could reduce the tax revenue by 15 billion Euro. Such a tax regime would increase the unequal distribution and polarisation of net incomes. The IW Koln suggested an alternative tax rate in 2008. This regime would increase unequal distribution and polarisation of disposable incomes to a greater extent than the FDP-tax rate. An implementation of this income tax scale would go along with losses in tax revenue of 18.8 billion Euro. Likewise, the implementation of a 2009 SPD tax rate proposal would reduce tax revenue by 14.8 billion Euro. Although this regime would reduce unequal distribution, the effect on the polarization of disposable incomes is not definitely predictable. In contrast to all the other scenarios, the realisation of the recent SPD tax rate proposal from 2011 could enlarge tax revenue by 4.7 billion Euro. This tax regime would reduce unequal distribution and polarisation of disposable incomes even more than the present tax system.

T1 - A dynamic life cycle model for Germany with unemployment uncertainty
T1 - Ein dynamisch, stochastisches Lebenszyklusmodell für Deutschland mit Beschäftigungsunsicherheit
N2 - This work analyzes the saving and consumption behavior of agents faced with the possibility of unemployment in a dynamic and stochastic life cycle model. The intertemporal optimization is based on Dynamic Programming with a backward recursion algorithm. The implemented uncertainty is not based on income shocks as it is done in traditional life cycle models but uses Markov probabilities where the probability for the next employment status of the agent depends on the current status. The utility function used is a CRRA function (constant relative risk aversion), combined with a CES function (constant elasticity of substitution) and has several consumption goods, a subsistence level, money and a bequest function.
N2 - Diese Arbeit modelliert das Spar- und Konsumverhalten von Individuen in Deutschland mit einem Lebenszyklusmodell. Dabei hat das Modell zwei Besonderheiten, erstens trifft die Möglichkeit arbeitslos zu werden nicht jeden Agenten des Models mit der gleichen Wahrscheinlichkeit, sondern wird von Bildungsabschluss und dem Beschäftigungsstatus des Agenten beeinflußt und zweitens weicht die verwendete Nutzenfunktion von den Standardnutzenfunktionen ab und implementiert Vererbung, Geld, verschiedene Güter und Subsistenzlevel. Der Optimierungsalgorithmus basiert auf Dynamischer Programmierung.

T1 - A factory operating system for extending existing factories to Industry 4.0
JF - Computers in industry : an international, application oriented research journal
N2 - Cyber-physical systems (CPS) have shaped the discussion about Industry 4.0 (I4.0) for some time. To ensure the competitiveness of manufacturing enterprises the vision for the future figures out cyber-physical production systems (CPPS) as a core component of a modern factory. Adaptability and coping with complexity are (among others) potentials of this new generation of production management. The successful transformation of this theoretical construct into practical implementation can only take place with regard to the conditions characterizing the context of a factory. The subject of this contribution is a concept that takes up the brownfield character and describes a solution for extending existing (legacy) systems with CPS capabilities.

T1 - A Local Dimension of Integration Policies? A Comparative Study of Berlin, Malmo, and Rotterdam
JF - International migration review
N2 - This study examines three theses on local integration policies by a qualitative comparative case study of integration policies in three cities in three different countries (Berlin, Malmo, and Rotterdam). We found little evidence of a congruent local dimension of integration policies. Local policies resemble their national policy frameworks fairly well in terms of policy approaches and domains. Our multi-level perspective shows that this is not the result of top-down hierarchical governance, but rather of a multilevel dynamic of two-way interaction. Local policy legacies and local politics matter and national policies are also influenced by local approaches of integration.

T1 - A note on merger in mixed duopoly - Bertrand versus Cournot
JF - Journal of economics
N2 - In this note we analyze the incentives to merge in a mixed duopoly if firms compete in prices or quantities. Our model framework mainly follows Barcena-Ruiz and Garzon (J Econ 80:27-42, 2003) who set up the model with quantity competition. We extend their analysis by analyzing the case of competition in prices. Further we compare the incentives to merge with Bertrand and Cournot competition. Comparing quantity with price competition we can show that a merger is more likely with Cournot competition than with Bertrand competition.

T1 - A paradox perspective on the interactive effects of visionary and empowering leadership
JF - Organizational Behavior and Human Decision Processes
N2 - In a multi-source, lagged design field study of 197 leader-follower dyads, we test a model that predicts positive interactive effects of visionary and empowering leadership on follower performance. Based on the paradox perspective, we argue that visionary and empowering leadership are synergistic in that their combination enables leaders to address a key paradox inherent to leader behavior identified by Waldman and Bowen (2016): Maintaining control while simultaneously letting go of control. We argue that visionary leadership addresses the former and empowering leadership addresses the latter pole of this pair of opposites. Hence, in line with paradox thinking, we posit that leaders will engender more positive effects on follower performance when they enact visionary and empowering leadership behaviors simultaneously and adopt a "both-and" approach, rather than focus on one of these behaviors without the other. Our results support our hypothesized interactive effect of visionary and empowering leadership on goal clarity, as well as a conditional indirect effect such that goal clarity mediates the interactive effect of visionary and empowering leadership on individual follower performance.

T1 - A Procedural Model for the Production of reusable and standard-compliant E-Learning Offerings
N2 - Cost-efficient production of high-quality learning contents is an important success factor for a sustainable and economic realisation of E-Learning. This necessitates the design of sustainable production processes, which create reusable Learning Objects and require minimal resources. In such a context, this contribution introduces a practical and business-process oriented Procedural Model for the Production of reusable and standard-compliant E-Learning Offerings. It has been developed and applied in a project that produces learning contents for a Master program of an international virtual university. After the introduction of a reengineering method, a special analysis instrument for E-Learning has been designed to analyse the existing production processes and to improve them in terms of efficiency, costs, standard- compliance, and process automation. The method introduced is hence not focussing on individual technical solutions but on the efficiency of the whole E-Learning production and value chain. It gives an orientation for establishing and maintaining sustainable and competitive E-Learning production processes with appropriate effort.

T1 - A question of time: responsive and responsible democratic politics
JF - West European politics
N2 - Since 2008, European crisis politics have thrown the importance of time in democracy into sharp relief. The need for rapid action by national authorities, the EU and international organisations conflicts with the time-consuming nature of democratic deliberation; short-term political firefighting has given little consideration to the long-term sustainability and time consistency of policies; and decentralised decisions threaten effective synchronisation within multi-level governance systems. This article suggests that democratic politics requires a balance between the temporal characteristics of responsive and responsible politics. The timeframe for responsive politics is shaped by electoral cycles that encourage speedy action; short-term lags between political choices and their effects; and temporal discretion of decision-makers. The timeframe for responsible politics is characterised by time-consuming procedures; solutions that take time to unfold and are sustainable in the longer term; and the purposive synchronisation amongst actors and across policy domains and levels of policy-making. The finely balanced temporal constitution of democracy has been challenged in two fundamental ways. First, as the ability of decision-makers to work within the time limits of their mandates and to respond to the temporal expectations of the electorate decreases, the temporal ties that ensure the responsiveness of political authority to the electorate weaken. Second, the distinct temporal qualities of majoritarian and non-majoritarian institutions that encourage responsibility are called into question. Consequently, political time in Europe runs the risk of becoming both less responsive and less responsible.

In this contribution an evolutionary simulation based on a monocentric city model with externalities among households is used to discuss the spatial segregation patterns of four groups. The resulting complex spatial patterns can be shown as graphic animations. They can be applied as initial situation for the analysis of the effects a rent control has on segregation.

T1 - A sustainable pathway to consumer wellbeing
BT - the role of anticonsumption and consumer empowerment
JF - The Journal of consumer affairs
N2 - This study investigates the effect of different anticonsumption constructs on consumer wellbeing. The study assumes that people will only lower their level of consumption if doing so does not also lower personal wellbeing. More precisely, this research investigates how specific subtypes of sustainable anticonsumption (e.g., voluntary simplicity, collaborative consumption, and debt-free living) relate to different states of consumer's wellbeing (e.g., financial, psychosocial, and subjective wellbeing). This work also examines whether consumer empowerment can improve personal wellbeing and strengthen the anticonsumption wellbeing relationship. The results show that voluntarily foregoing consumption does not reduce wellbeing and consumer empowerment plays a significant role in supporting sustainable pathways to consumer wellbeing. This study reasons that empowerment improves consumer sovereignty, but may be detrimental for consumers heavily concerned about debt-free living. The present investigation concludes by proposing implications for public and consumer policymakers wishing to promote appropriate sustainable (anticonsumption) pathways to consumer wellbeing.

T1 - A tale of two tails: Explaining extreme events in financialized agricultural markets
JF - Food policy : economics planning and politics of food and agriculture
N2 - The substantial booms and busts in agricultural prices marked by extreme events across commodities lead to heated debates about the effects of speculative trading on commodity price fluctuations. This study proposes a new approach to understanding extreme events and boom-bust processes in agricultural markets. Using weekly futures data for twelve indexed agricultural commodities during 2006 to 2016, we find that extreme price changes, located in the 10% tails of the distribution, cluster across agricultural markets. We then implement a multinomial logit model to investigate which factors are associated with the propagation of extreme events. Specifically, we disentangle three transmission conduits. (1) The macroeconomic conduit captures the possibility that the synchronized extreme price events are generated by business-cycle driven demand shifts mainly in emerging economies. (2) The financial conduit refers to potential links between extreme returns and the increasing flow of money from financial participants into agricultural futures markets. (3) Finally, the energy conduit accounts for possible spillover effects due to oil price shocks. Our results indicate an important role of managed money positions and oil prices while the real demand channel remains mostly insignificant. (C) 2017 Elsevier Ltd. All rights reserved.

T1 - A vector error correction model for the relationship between public debt and inflation in Germany
N2 - In the paper, the interaction between public debt and inflation including mutual impulse response will be analysed. The European sovereign debt crisis brought once again the focus on the consequences of public debt in combination with an expansive monetary policy for the development of consumer prices. Public deficits can lead to inflation if the money supply is expansive. The high level of national debt, not only in the Euro-crisis countries, and the strong increase in total assets of the European Central Bank, as a result of the unconventional monetary policy, caused fears on inflating national debt. The transmission from public debt to inflation through money supply and long-term interest rate will be shown in the paper. Based on these theoretical thoughts, the variables public debt, consumer price index, money supply m3 and long-term interest rate will be analysed within a vector error correction model estimated by Johansen approach. In the empirical part of the article, quarterly data for Germany from 1991 by 2010 are to be examined.

Planetary boundaries define limits for biophysical systems and processes that regulate the stability and life support capacity of the Earth system, and thereby also define a safe operating space for humanity on Earth. Budgets associated to planetary boundaries can be understood as global commons: common pool resources that can be utilized within finite limits. Despite the analytical interpretation of planetary boundaries as global commons, the planetary boundaries framework is missing a thorough integration into economic theory. We aim to bridge the gap between welfare economic theory and planetary boundaries as derived in the natural sciences by presenting a unified theory of cost-benefit and cost-effectiveness analysis. Our pragmatic approach aims to overcome shortcomings of the practical applications of CEA and CBA to environmental problems of a planetary scale. To do so, we develop a model framework and explore decision paradigms that give guidance to setting limits on human activities. This conceptual framework is then applied to planetary boundaries. We conclude by using the realized insights to derive a research agenda that builds on the understanding of planetary boundaries as global commons.

N2 - Wandlungsfähigkeit von Informationssystemen ist zu einem wesentlichen Wettbewerbsfaktor geworden. Die derzeit unzureichende methodische Unterstützung zur Umsetzung von Wandlungsfähigkeit führt in Unternehmen häufig zu ungenutzten Potentialen einer leistungsfähigen Struktur durch die eingesetzte Informationstechnologie. Ziel des Forschungsprojektes CHANGE ist es, Methoden und Vorgehensmodelle zu entwickeln, die eine dauerhafte Wandlungsfähigkeit von Informationssystemen unterstützen. Dazu wird im Rahmen dieses Beitrages ein Verfahren vorgestellt, welches der Forderung zur Ermittlung der notwendigen Wandlungsfähigkeit unter Einbeziehung des Unternehmensumfeldes nachkommt. Als wesentliches Ergebnis wird ein Kennzahlensystem entwickelt, das zum einen die Umweltsituation als Indikator für den Wandlungsdruck eines Unternehmens beschreibt. Im nächsten Schritt werden Kriterien zur Ermittlung des Wandlungspotentials der eingesetzten IT herangezogen. Abschließend werden beide Dimensionen zusammengeführt und in ihrer Bedeutung für die IT Strategie eines Unternehmens interpretiert.

T1 - Active social media use and its impact on well-being
BT - an experimental study on the effects of posting pictures on Instagram
JF - Journal of computer-mediated communication : a journal of the International Communication Association
N2 - Active use of social networking sites (SNSs) has long been assumed to benefit users' well-being. However, this established hypothesis is increasingly being challenged, with scholars criticizing its lack of empirical support and the imprecise conceptualization of active use. Nevertheless, with considerable heterogeneity among existing studies on the hypothesis and causal evidence still limited, a final verdict on its robustness is still pending. To contribute to this ongoing debate, we conducted a week-long randomized control trial with N = 381 adult Instagram users recruited via Prolific. Specifically, we tested how active SNS use, operationalized as picture postings on Instagram, affects different dimensions of well-being. The results depicted a positive effect on users' positive affect but null findings for other well-being outcomes. The findings broadly align with the recent criticism against the active use hypothesis and support the call for a more nuanced view on the impact of SNSs.

N2 - This paper studies the effect of cultural attitudes on childcare provision, fertility, female labour supply and the gender wage gap. Cross-country data show that fertility, female labour force participation and childcare provision are positively correlated with each other, while the gender wage gap seems to be negatively correlated with these variables. The paper presents a model with endogenous fertility, female labour supply and childcare choices driven by cultural attitudes which fits these facts. There may exist multiple equilibria: one with zero childcare provision, low fertility and female labour supply and high wage gap and one with high childcare provision, high fertility and female labour supply and low wage gap.

T1 - Adopting wearables to customize health insurance contributions
BT - a ranking-type Delphi
JF - BMC medical informatics and decision making
N2 - Background
Wearables, as small portable computer systems worn on the body, can track user fitness and health data, which can be used to customize health insurance contributions individually. In particular, insured individuals with a healthy lifestyle can receive a reduction of their contributions to be paid. However, this potential is hardly used in practice.
Objective
This study aims to identify which barrier factors impede the usage of wearables for assessing individual risk scores for health insurances, despite its technological feasibility, and to rank these barriers according to their relevance.
Methods
To reach these goals, we conduct a ranking-type Delphi study with the following three stages. First, we collected possible barrier factors from a panel of 16 experts and consolidated them to a list of 11 barrier categories. Second, the panel was asked to rank them regarding their relevance. Third, to enhance the panel consensus, the ranking was revealed to the experts, who were then asked to re-rank the barriers.
Results
The results suggest that regulation is the most important barrier. Other relevant barriers are false or inaccurate measurements and application errors caused by the users. Additionally, insurers could lack the required technological competence to use the wearable data appropriately.
Conclusion
A wider use of wearables and health apps could be achieved through regulatory modifications, especially regarding privacy issues. Even after assuring stricter regulations, users’ privacy concerns could partly remain, if the data exchange between wearables manufacturers, health app providers, and health insurers does not become more transparent.

JF - Information systems and e-business management
N2 - The paper presents the implementation of Business Process Management in a large international company. The business case illustrates the main objectives and approach taken with the BPM initiative. Central element of the BPM implementation was the development of a process framework which consists of a reference process house (RPH) and common methods for process management across the company. In order to assess the implementation of Business Process Management and the achievements a process management maturity assessment was developed and implemented. The maturity model is based on nine categories which comprehensively cover all aspects which impact the success of Business Process Management. Some findings of the first assessment cycle are pinpointed to illustrate the benefits and best practice exchange as a result of the assessment.

T1 - Aktuelle Entwicklungen des Hochschulmarketing in Deutschland : am Beispiel der Region Berlin/Brandenburg
T1 - Current developments in the marketing of Germany’s higher education system : the example of the region Berlin/Brandenburg
N2 - 1. Problemstellung und Relevanz des Themas Die deutsche Hochschullandschaft hat in den letzten Jahren zahlreiche Veränderungen bewältigen müssen und steht weiterhin großen Herausforderungen gegenüber, durch welche sich zunehmend wettbewerbsähnliche Merkmale in diesem Sektor verfestigen: • Umstellung auf international vergleichbare Studiengänge • Neuregelung der Studienplatzvergabe • Einführung von Studiengebühren in einigen Bundesländern • Leistungsindikatoren zur Verteilung der staatlichen Haushaltsmittel • Demographischer Wandel Eine Bildungseinrichtung besitzt mehrere Anspruchsgruppen: die Studierenden, welche Bildungsleistungen nachfragen, den Staat, der für die Leistungen zahlt, die Öffentlichkeit, die an Grundlagenforschungen interessiert ist und schließlich die Wirtschaft, die Absolventen rekrutiert (vgl. Berthold, C. 2001, S.431). Die Hochschulen befinden sich untereinander verstärkt im Wettbewerb um qualifizierte (und ggf. zahlungswillige) Studierende, um finanzielle Mittel vom Staat oder aus der Privatwirtschaft und um renommierte Wissenschaftler. Hochschulen müssen sich nun den veränderten Bedingungen anpassen, um auch weiterhin im nationalen und internationalen Wettbewerb überlebensfähig zu bleiben. Grundsätzlich kann sich hierbei an in der Privatwirtschaft erfolgreich eingesetzten Marketinginstrumenten orientiert werden. 2. Zielsetzung und Aufbau der Arbeit Nach einer Analyse der oben genannten Rahmenbedingungen, wird im ersten Teil dieser Arbeit gezeigt, welche Erkenntnisse aus dem Marketing auf Hochschulen übertragen werden können. Dabei werden sowohl strategische Fragen beleuchtet als auch die Instrumente des Marketing-Mix vorgestellt. In einer anschließenden Untersuchung wurden Faktoren bestimmt, welche sich positiv auf den Entwicklungsstand von Marketingaktivitäten an Hochschulen auswirken. Dabei konnten - beispielhaft für die Region Berlin/Brandenburg - sechs verschiedene Hochschultypen identifiziert werden. Diese weisen, in Abhängigkeit der verschiedenen Eigenschaften der jeweiligen Institutionen, einen unterschiedlichen Entwicklungsstand oder ein anderes Verständnis von Hochschulmarketing auf. Aufgrund dessen erscheinen für sie jeweils andere Marketingstrategien empfehlenswert. Die größte Rolle für den differenzierten Status quo im Hochschulmarketing an Berliner und Brandenburger Hochschulen spielt die Stärke des äußeren Drucks unter dem sich die Hochschule befindet, um ihre Auslastung und die notwendige finanzielle Ausstattung sicherzustellen. Ferner unterscheiden sich die Hochschulleitungen erheblich in ihrem Engagement und der Bereitschaft, diesen Herausforderungen mit Marketinginstrumenten zu begegnen. Trotz der gestiegenen Anzahl von Beiträgen zur Notwendigkeit der Einführung von ökonomischen Überlegungen auch im Hochschulmanagement gibt es viele Kritiker, die ein Ende der Freiheit für Forschung und Lehre prophezeien, wenn der Marketing-Gedanke verstärkt auch an Bildungseinrichtungen Einzug hält. Unumstritten ist, dass Managementansätze aus der privaten Wirtschaft nicht ohne weiteres auf eine Hochschule adaptiert werden können. Wahrscheinlich besteht jedoch die größere Gefahr für Freiheit und Erfolg von Forschung und Lehre in der Missachtung dieser aktuellen Tendenzen (vgl. Tutt 2006, S. 171)!
N2 - 1. Problem and Importance Germany’s academic landscape has dealt with several transformations recently and still faces enormous challenges, which have resulted in the ever-increasing competitive nature within the educational sector: • reorganization of educational degrees for international comparability • adjustments in the allocation of places available for study • initiation of tuition fees in some federal states • efficiency indicators for resource allocation of public funds • demographic change An educational institution has several groups of interest: students who demand educational services, the state which pays for the these services, the general public that is interested in fundamental research and an economic system that recruits qualified graduates (cf. Berthold, 2001, p. 431). Institutions of higher education compete among each other for competent students (who are willing to pay if necessary), qualified scientists and public funding or means from the private sector. To remain viable competitors on a national and international level, institutions of higher education need to adapt themselves to changing conditions. Here it is possible to utilize the successfully applied marketing tools from the private sector. 2. Goal and Structure of this Thesis After an analysis of the above mentioned general conditions, the first part of this thesis will explore which marketing strategies can be adapted for higher education institutions. Both, strategic questions and marketing tools will be discussed. A subsequent research defined criteria, which have a positive impact on the stage of development of marketing-activities in institutions of higher education. Six different types of educational institutions could be identified for the region Berlin/Brandenburg. Depending on the different characteristics ofeach institution, they exhibit a variety of stages of development or diverse understandings of marketing for higher education. Thus, differing marketing strategies can be recommended in each case. The most important factor in the differences in the marketing management of higher education institutions in Berlin and Brandenburg is the level of intensity of external pressure put on these establishments in order to guarantee the maximum utilization of resources and financial strength. Furthermore, the institution’s administrations differ in the commitment and willingness to respond to these challenges with marketing tools. Despite the increasing number of papers written on the necessity to introduce economic considerations into the management of higher education institutions, there are many critics that prognosticate the end of freedom within research and teaching if the spirit of marketing enters into education. Though it is an indisputable fact that management approaches from the private sector cannot be adapted into educational institutions without changes, freedom within research and teaching possibly faces a bigger threat from the disregard of these current changes and developments (cf. Tutt 2006, p. 171)!

T1 - Alcohol availability and alcohol-attributable mortality
BT - economic implications following a change in sales policy
JF - CESifo economic studies : CESifo, a joint initiative of the University of Munich's Center for Economic Studies and the Ifo Institute
N2 - It is commonly known that irresponsible alcohol use can have adverse effects. For some people, it results in health problems, for others in productivity loss, and some experience the worst possible outcome of alcohol misuse - death. This paper estimates the effect of reduced alcohol sales hours on alcohol-attributable mortality (AAM) in Estonia. Using novel mortality data from 1997 to 2015, this paper analyzes the effect of alcohol sales policies at both the county level and the country level. By applying the difference-in-differences method and the ARIMA model, this paper finds that the alcohol sales policy reduced AAM to between 1.710 and 2.401 deaths per 100,000 per month, which equals a reduction of 31% to 40% in AAM deaths. These findings suggest that individuals who are the most at risk of dying from alcohol-attributable causes of death benefit remarkably from reduced alcohol availability.

T1 - Alcohol control policies in Former Soviet Union countries
BT - a narrative review of three decades of policy changes and their apparent effects
JF - Drug and alcohol review
N2 - Issues The last Soviet anti-alcohol campaign of 1985 resulted in considerably reduced alcohol consumption and saved thousands of lives. But once the campaign's policies were abandoned and the Soviet alcohol monopoly broken up, a steep rise in mortality was observed in many of the newly formed successor countries, although some kept their monopolies. Almost 30 years after the campaign's end, the region faces diverse challenges in relation to alcohol.
Approach The present narrative review sheds light on recent drinking trends and alcohol policy developments in the 15 Former Soviet Union (FSU) countries, highlighting the most important setbacks, achievements and best practices. Vignettes of alcohol control policies in Belarus, Estonia, Kazakhstan, Lithuania and Uzbekistan are presented to illustrate the recent developments.
Key Findings Over the past decade, drinking levels have declined in almost all FSU countries, paralleled by the introduction of various alcohol-control measures. The so-called three 'best buys' put forward by the World Health Organization to reduce alcohol-attributable burden (taxation and other measures to increase price, restrictions on alcohol availability and marketing) are relatively well implemented across the countries.
Implications In recent years, evidence-based alcohol policies have been actively implemented as a response to the enormous alcohol-attributable burden in many of the countries, although there is big variance across and within different jurisdictions.
Conclusion Strong declines in alcohol consumption were observed in the 15 FSU countries, which have introduced various alcohol control measures in recent years, resulting in a reduction of alcohol consumption in the World Health Organization European region overall.

T1 - Algorithmic Trading
BT - Analyse von computergesteuerten Prozessen im Wertpapierhandel unter Verwendung der Multifaktorenregression
BT - analysis of computer driven processes in securities trading using a multifactor regression model
N2 - Die Elektronisierung der Finanzmärkte ist in den letzten Jahren weit vorangeschritten. Praktisch jede Börse verfügt über ein elektronisches Handelssystem. In diesem Kontext beschreibt der Begriff Algorithmic Trading ein Phänomen, bei dem Computerprogramme den Menschen im Wertpapierhandel ersetzen. Sie helfen dabei Investmententscheidungen zu treffen oder Transaktionen durchzuführen. Algorithmic Trading selbst ist dabei nur eine unter vielen Innovationen, welche die Entwicklung des Börsenhandels geprägt haben. Hier sind z.B. die Erfindung der Telegraphie, des Telefons, des FAX oder der elektronische Wertpapierabwicklung zu nennen. Die Frage ist heute nicht mehr, ob Computerprogramme im Börsenhandel eingesetzt werden. Sondern die Frage ist, wo die Grenze zwischen vollautomatischem Börsenhandel (durch Computer) und manuellem Börsenhandel (von Menschen) verläuft. Bei der Erforschung von Algorithmic Trading wird die Wissenschaft mit dem Problem konfrontiert, dass keinerlei Informationen über diese Computerprogramme zugänglich sind. Die Idee dieser Dissertation bestand darin, dieses Problem zu umgehen und Informationen über Algorithmic Trading indirekt aus der Analyse von (Fonds-)Renditen zu extrahieren. Johannes Gomolka untersucht daher die Forschungsfrage, ob sich Aussagen über computergesteuerten Wertpapierhandel (kurz: Algorithmic Trading) aus der Analyse von (Fonds-)Renditen ziehen lassen. Zur Beantwortung dieser Forschungsfrage formuliert der Autor eine neue Definition von Algorithmic Trading und unterscheidet mit Buy-Side und Sell-Side Algorithmic Trading zwei grundlegende Funktionen der Computerprogramme (die Entscheidungs- und die Transaktionsunterstützung). Für seine empirische Untersuchung greift Gomolka auf das Multifaktorenmodell zur Style-Analyse von Fung und Hsieh (1997) zurück. Mit Hilfe dieses Modells ist es möglich, die Zeitreihen von Fondsrenditen in interpretierbare Grundbestandteile zu zerlegen und den einzelnen Regressionsfaktoren eine inhaltliche Bedeutung zuzuordnen. Die Ergebnisse dieser Dissertation zeigen, dass man mit Hilfe der Style-Analyse Aussagen über Algorithmic Trading aus der Analyse von (Fonds-)Renditen machen kann. Die Aussagen sind jedoch keiner technischen Natur, sondern auf die Analyse von Handelsstrategien (Investment-Styles) begrenzt.
N2 - During the last decade the electronic trading on the stock exchanges advanced rapidly. Today almost every exchange is running an electronic trading system. In this context the term algorithmic trading describes a phenomenon, where computer programs are replacing the human trader, when making investment decisions or facilitating transactions. Algorithmic trading itself stands in a row of many other innovations that helped to develop the financial markets technologically (see for example telegraphy, the telephone, FAX or electronic settlement). Today the question is not, whether computer programs are used or not. The question arising is rather, where the border between automatic, computer driven and human trading can be drawn. Conducting research on algorithmic trading confronts scientists always with the problem of limited availability of information. The idea of this dissertation is to circumnavigate this problem and to extract information indirectly from an analysis of a time series of (fund)-returns data. The research question here is: Is it possible to draw conclusions about algorithmic trading from an analysis of (funds-)return data? To answer this question, the author develops a complete definition of algorithmic trading. He differentiates between Buy-Side and Sell-Side algorithmic trading, depending on the functions of the computer programs (supporting investment-decisions or transaction management). Further, the author applies the multifactor model of the style analysis, formely introduced by Fung and Hsieh (1997). The multifactor model allows to separate fund returns into regression factors that can be attributed to different reasons. The results of this dissertation do show that it is possible to draw conclusions about algorithmic trading out of the analysis of funds returns. Yet these conclusions cannot be of technical nature. They rather have to be attributed to investment strategies (investment styles).

BT - Leveraging the composition and size of the negotiating package
JF - The journal of business & industrial marketing
N2 - Purpose:
While industrial marketers have long bundled their products and services to sell them as packages, to what extent should negotiators also rely on packaging their offers? Clearly, negotiating at a package level can tax the cognitive capacity of the involved parties at some point. Therefore, this study aims to analyze the impact of the number and type of issues that should be negotiated simultaneously to leverage the package strategy efficiently and effectively in multi-issue buyer-seller negotiations.
Design/methodology/approach:
The authors conducted and analyzed negotiation simulations with 676 students from 2 public universities.
Findings:
The authors’ results suggest that negotiating three out of six issues simultaneously is the least efficient but most effective strategy in multi-issue buyer-seller negotiations. Moreover, they found that bundling distributive and integrative issues is more efficient and effective than only bundling distributive or integrative negotiation issues in a package offer.
Originality/value:
Past research has examined the impact of negotiating a package as compared to each issue separately; however, little empirical attention has been directed toward understanding how to apply a package strategy in complex multi-issue negotiations.

BT - climate policy when assets can become stranded
JF - Journal of environmental economics and management
N2 - This paper develops a new perspective on stranded assets in climate policy using a partial equilibrium model of the energy sector. Political-economy related aspects are considered in the government's objective function. Lobbying power of firms or fiscal considerations by the government lead to time inconsistency: The government will deviate from a previously announced carbon tax which creates stranded assets. Under rational expectations, we show that a time-consistent policy outcome exists with either a zero carbon tax or a prohibitive carbon tax that leads to zero fossil investments - an "all-or-nothing" policy. Although stranded assets are crucial to such a bipolar outcome, they disappear again under time-consistent policy. Which of the two outcomes (all or nothing) prevails depends on the lobbying power of owners of fixed factors (land and fossil resources) but not on fiscal revenue considerations or on the lobbying power of renewable or fossil energy firms.

N2 - In the past academic libraries in Germany have been successfully undertaking joint endeavors toward a social and political definition of the knowledge society by cooperatively developing ways to provide information and increasing the digital forms of metadata and media. In doing so, they have unintentionally created the basis for a competitive playing field in which the individual library must establish strategic positions for success if it is to maintain viability and ensure continuous flow of resources. This article develops a framework for discussing such alternative and potentially successful strategies from the point of view of a university library

JF - Electronic markets : EM ; the international journal of electronic commerce and business media
N2 - The healthcare industry has been slow to adopt new technologies and practices. However, digital and data-enabled innovations diffuse the market, and the COVID-19 pandemic has recently emphasized the necessity of a fundamental digital transformation. Available research indicates the relevance of digital platforms in this process but has not studied their economic impact to date. In view of this research gap and the social and economic relevance of healthcare, we explore how digital platforms might affect value creation in this market with a particular focus on Google, Apple, Facebook, Amazon, and Microsoft (GAFAM). We rely on value network analyses to examine how GAFAM platforms introduce new value-creating roles and mechanisms in healthcare through their manifold products and services. Hereupon, we examine the GAFAM-impact on healthcare by scrutinizing the facilitators, activities, and effects. Our analyses show how GAFAM platforms multifacetedly untie conventional relationships and transform value creation structures in the healthcare market.

Drawing on 18 months of participant observations and 38 interviews conducted in a Big 4 accounting firm, we develop a multi-level model of error management. With this model, we propose how organizational structures, team procedures and practices, and individual cognitions and emotions interact to manage errors. The multi-level model of error management allows us to conceptually integrate previous behavioral and social research on audit quality, contributes to the rising accounting firm error management literature, and explains how and why two general approaches from the broader error management literature to errors that are usually considered as opposing each other, i.e., error prevention and error resilience, may interact and actually entail each other in accounting firms.

T1 - An expert-based Bayesian investigation of greenhouse gas emission reduction options for German passenger vehicles until 2030
T1 - Eine Expertenbasierte Bayesianische Untersuchung von Möglichkeiten zur Reduktion der Treibhausgasemissionen der Deutschen Neuwagenflotte bis 2030
N2 - The present thesis introduces an iterative expert-based Bayesian approach for assessing greenhouse gas (GHG) emissions from the 2030 German new vehicle fleet and quantifying the impacts of their main drivers. A first set of expert interviews has been carried out in order to identify technologies which may help to lower car GHG emissions and to quantify their emission reduction potentials. Moreover, experts were asked for their probability assessments that the different technologies will be widely adopted, as well as for important prerequisites that could foster or hamper their adoption. Drawing on the results of these expert interviews, a Bayesian Belief Network has been built which explicitly models three vehicle types: Internal Combustion Engine Vehicles (which include mild and full Hybrid Electric Vehicles), Plug-In Hybrid Electric Vehicles, and Battery Electric Vehicles. The conditional dependencies of twelve central variables within the BBN - battery energy, fuel and electricity consumption, relative costs, and sales shares of the vehicle types - have been quantified by experts from German car manufacturers in a second series of interviews. For each of the seven second-round interviews, an expert's individually specified BBN results. The BBN have been run for different hypothetical 2030 scenarios which differ, e.g., in regard to battery development, regulation, and fuel and electricity GHG intensities. The present thesis delivers results both in regard to the subject of the investigation and in regard to its method. On the subject level, it has been found that the different experts expect 2030 German new car fleet emission to be at 50 to 65% of 2008 new fleet emissions under the baseline scenario. They can be further reduced to 40 to 50% of the emissions of the 2008 fleet though a combination of a higher share of renewables in the electricity mix, a larger share of biofuels in the fuel mix, and a stricter regulation of car CO$_2$ emissions in the European Union. Technically, 2030 German new car fleet GHG emissions can be reduced to a minimum of 18 to 44% of 2008 emissions, a development which can not be triggered by any combination of measures modeled in the BBN alone but needs further commitment. Out of a wealth of existing BBN, few have been specified by individual experts through elicitation, and to my knowledge, none of them has been employed for analyzing perspectives for the future. On the level of methods, this work shows that expert-based BBN are a valuable tool for making experts' expectations for the future explicit and amenable to the analysis of different hypothetical scenarios. BBN can also be employed for quantifying the impacts of main drivers. They have been demonstrated to be a valuable tool for iterative stakeholder-based science approaches.
N2 - Die vorliegende Arbeit verfolgt zwei Forschungsziele - ein inhaltliches und ein methodisches. Auf der inhaltlichen Ebene wurde die Entwicklung der CO2-Emissionen der deutschen Neuwagenflotte bis 2030 untersucht. Es wurden verschiedene technische Möglichkeiten daraufhin überprüft, inwieweit sie zur Emissionsminderung beitragen können, wie wahrscheinlich es ist, dass sie umgesetzt werden, und welche Voraussetzungen und Rahmenbedingungen bedeutenden Einfluß haben. Die methodische Innovation dieser Arbeit besteht darin, subjektive Einschätzungen von Experten mit einem Bayesianischen Netzwerk zu verknüpfen, um die Anwendung solcher Netzwerke auf Situationen von Unsicherheit im Knight'schen Sinne zu erweitern, hier am Beispiel der zukünftigen, heute nicht vorhersagbaren Entwicklung der CO2-Emissionen der deutschen Neuwagenflotte. Ein erster Schritt dieser Untersuchung bestand in der Erhebung und Auswertung der Einschätzungen von 15 Experten in Bezug auf die Möglichkeiten, die CO2-Emissionen neuer PKW in Deutschland bis 2020 zu senken. Erhoben wurden Aussagen über verfügbare Technologien, ihre Einsparpotenziale, ihre Umsetzungswahrscheinlichkeiten sowie wichtige Rahmenbedingungen. Ziel war es, wesentliche Variablen und deren Abhängigkeiten zu identifizieren, um eine Grundlage für die spätere Modellierung zu schaffen. Um die Untersuchung auf eine breite Basis zu stellen, wurden Experten von Autobauern und Zulieferern, Nichtregierungsorganisationen, Verbänden sowie solche aus Wissenschaft und Journalismus einbezogen. Aufbauend auf diesen Ergebnissen wurde in einem zweiten Schritt ein Bayesianisches Netzwerk entwickelt, mit dem die CO2-Emissionen der deutschen Neuwagenflotte im Jahr 2030 quantifiziert werden können. Außerdem sollten die Marktchancen verschiedener Fahrzeugtypen untersucht werden. Ein weiteres Ziel war es, den Einfluss verschiedener technologischer und regulatorischer Einflussfaktoren zu quantifizieren, die in der ersten Interviewrunde identifiziert worden waren. Gegenüber der ersten Interviewrunde wurde der zeitliche Rahmen der Untersuchung um 10 Jahre auf das Jahr 2030 erweitert. Das Bayesianische Netz erstreckt sich auf die zukünftigen Eigenschaften und Marktchancen von drei Fahrzeugtypen: Verbrennungsmotorische Fahrzeuge einschließlich aller Hybridvarianten bis hin zum Vollhybrid, Plug-In Hybride und Batterie-Elektrofahrzeuge. Das Netzwerk umfasst 46 miteinander verknüpfte Variablen. Für zwölf entscheidende Variablen wurden per Expertenbefragung bedingte Wahrscheinlichkeiten erhoben. Befragt wurden sieben Experten, fast alle hochrangige F&E- oder Umweltexperten bei deutschen Autobauern. Für jeden Experten entstand ein individuell quantifiziertes Netzwerk. Um mögliche Technologie- und Emissionspfade zu untersuchen, wurden verschiedene Szenarien definiert, die unterschiedliche Regulierungen, Batterie-Entwicklungspfade und CO2-Intensitäten von Treibstoffen und elektrischer Energie in Betracht ziehen. Im Basis-Szenario liegen die Erwartungswerte der CO2-Emissionen der deutschen Neuwagenflotte 2030 nach Einschätzung der Experten bei 50 bis 65% der Emissionen der Neuwagenflotte 2008. Kombiniert man einen gesteigerten Anteil erneuerbarer Energien im Strommix, einen größeren Anteil von Biotreibstoffen im Treibstoff-Mix und eine strengere CO2-Emissionsregulierung seitens der Europäischen Union, liegen die erwarteten Emissionen der Neuwagenflotte 2030 bei 40 bis 50% der Emissionen der Neuwagen 2008. Die Erwartungswerte der Neuflotten-Emissionen 2030 können in den verschiedenen BBN auf minimale Werte von 18 bis 44% der Emissionen der deutschen Neuwagenflotte von 2008 festgelegt werden. Es ist in den BBN durchaus möglich, aber in den betrachteten Szenarien unwahrscheinlich, die Emissionen so stark zu senken. Neben der Untersuchung von Fahrzeugtechnologien und CO2-Emissionen bis 2030 verfolgte die vorliegende Arbeit das Ziel, eine innovative Methode zu erproben. Es hat meines Wissens bisher kein Experten-basiertes BBN gegeben, das zukünftige Entwicklungen untersucht. Eine weitere Besonderheit des Ansatzes ist, dass für jeden Experten ein eigenes BBN quantifiziert wurde, so dass eine Schar von Netzwerken entstanden ist, deren Aussagen verglichen werden können. Dadurch war es möglich, die Bandbreite der Erwartungen verschiedener Experten abzuleiten und festzustellen, wo Erwartungen relativ konsistent sind, und wo sie weit auseinander liegen. Daraus lassen sich wertvolle Schlüsse ableiten, an welchen Punkten weitere Forschung besonders erfolgversprechend ist. BBN haben sich damit als nützliches Werkzeug für Stakeholder-basierte iterative Forschungsprozesse erwiesen. Insgesamt hat es sich als fruchtbarer neuer Ansatz erwiesen, Experten-basierte Bayesianische Netzwerke zur Untersuchung zukünftiger Entwicklungsmöglichkeiten heranzuziehen. Die Methode ermöglicht es auch, den Einfluß von Rahmenbedingungen zu bestimmen.

T1 - An individual perspective on open innovation capabilities in the context of haute cuisine
JF - International journal of innovation in management
N2 - Previous research on open innovation (OI) has primarily focused on the organisational level of R&D intensive industries. With this paper, we contribute to research on the individual level of analysis by analysing specific perspectives in the context of creative industries. Our study is based on 36 interviews with Haute cuisine chefs in France, Germany, Great Britain, Italy, Spain, Sweden, and Switzerland listed in the 2012 Michelin Guide. Building on the OI capability concept, our results demonstrate that chefs use absorptive and desorptive capacity (AC, DC) as means to generate and market culinary innovations, respectively. Moreover, we found that chefs almost exclusively rely on their own inventive and innovative capabilities in the early stages of the culinary innovation process. In subsequent phases, however, chefs increasingly integrate other sources such as employees, suppliers, and guests. Our study contributes to the literature in two ways. First, we research the individual level within the OI process, and second, we provide insight into OI practices in the creative industries.

T1 - An overwiew of benefits and risks in open innovation projects and the influence of intermediary participation, decision-making authority, experience, and position on their perception
JF - International journal of innovation management : IJIM
N2 - This paper presents an exploratory study investigating the influence of the factors (1) intermediary participation, (2) decision-making authority, (3) position in the enterprise, and (4) experience in open innovation on the perception and assessment of the benefits and risks expected from participating in open innovation projects. For this purpose, an online survey was conducted in Germany, Austria and Switzerland. The result of this paper is an empirical evidence showing whether and how these factors affect the perception of potential benefits and risks expected within the context of open innovation project participation. Furthermore, the identified effects are discussed against the theory. Existing theory regarding the benefits and risks of open innovation is expanded by (1) finding that they are perceived mostly independently of the factors, (2) confirming the practical relevance of benefits and risks, and (3) enabling a finer distinction between their degrees of relevance according to respective contextual specifics.

N2 - Helping overcome distance, the use of videoconferencing tools has surged during the pandemic. To shed light on the consequences of videoconferencing at work, this study takes a granular look at the implications of the self-view feature for meeting outcomes. Building on self-awareness research and self-regulation theory, we argue that by heightening the state of self-awareness, self-view engagement depletes participants’ mental resources and thereby can undermine online meeting outcomes. Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment. The criticality of the communication role is put forward: looking at self while listening to other attendees has a negative direct and indirect effect on meeting outcomes; however, looking at self while speaking produces equivocal effects.
