We present a new approach for classifying MPEG-2 video sequences as dasiacartoonpsila, dasiacommercialpsila, dasiamusicpsila, dasianewspsila or dasiasportpsila by analyzing specific, high-level audio-visual features of consecutive frames in real-time. This is part of the well-known video-genre-classification problem, where popular TV-broadcast genres are studied. Such applications have also been discussed in the context of MPEG-7 [1]. In our method the extracted features are logically combined using a set of classifiers to produce a reliable recognition. The results demonstrate a high identification rate based on a large representative collection of 100 video sequences (20 sequences per genre) gathered from free digital TV-broadcasting in Europe.
In this paper we describe in detail the recent publications related to video-genre-classification and present our improved new approaches for classifying video sequences in real-time as 'cartoon', 'commercial', 'music', 'news' or 'sport' by analyzing the content with new high-level audio-visual descriptors and classification methods. Such applications have also been discussed in the context of MPEG-7. The results demonstrate identification rates of more than 90% based on a large representative collection of 100 videos gathered from free digital TV and Internet.
Wo genau liegt der technische Unterschied zwischen Fernsehern mit HD-ready und Full-HD? Welche Übertragungswege und Empfangsmöglichkeiten gibt es, und welche Zusatzgeräte brauchen die Verbraucher, um die verbesserte Bildqualität ihrer hochauflösenden TV-Geräte voll nutzen zu können? Und ist es wichtig, ob sich das Fernsehbild „progressiv“ oder „interlaced“ aufbaut? Antworten auf diese und weitere Fragen gibt die neue Publikation „HD-TV – Technologische Einblicke in das hochauflösende Fernsehen der Zukunft“.
Dr. Ronald Glasberg (Technische Universität Berlin) hat im Auftrag des BITKOM einen Leitfaden zu grundlegenden, technologischen Einblicken in das hochauflösende Fernsehen der Zukunft erstellt. Die Publikation weist die optionalen Übertragungswege via Terrestrik, Kabel, Satellit, Mobilfunk oder Internet auf. Vor allem die digitalen Übertragungswege ermöglichen dem Konsumenten viele Annehmlichkeiten wie zeitversetztes Fernsehen, Video-on-Demand, das Auffinden von Schlüsselbegriffen im laufenden Programm sowie zukünftig mehr Interaktivität.
It is often claimed that work opportunities decline with age, that hiring chances of older persons are poor. We investigate this by collecting questionnaire responses from personnel managers of German manufacturing firms, eliciting a hypothetical hiring decision based on three fictitious candidates. We rely on an age-neutral job and a small age-gap of 14 years between the youngest and the oldest candidate. The quasi-experimental design of the questionnaire allows us to control for possible productivity differences and other economic explanations for declining hiring chances. The data show a 60 percentage point difference in hiring probabilities between the youngest and oldest candidate.
Using a questionnaire and a sample of students and personnel managers we establish the existence of age discrimination in the hiring process in Germany and Norway. As expected, age discrimination is more prominent in Germany where the hiring probability of equally qualified applicants is reduced by about 22 percentage points due to an age differential of 14 years as opposed to only 12 percentage points in Norway. Within both countries the tendency to discriminate does not differ between students and personnel managers and does not depend on the age of the decision maker.
Teams with strong faultlines often do not achieve their full potential because their functioning is impaired. We argue that strong diversity beliefs held by team leaders mitigate the negative impact of socio-demographic and experience-based faultlines on team functioning. In a heterogeneous multisource field sample of 217 employees nested in 44 teams and their leaders, we tested our assumptions. Results of a path-analytic model showed that socio-demographic faultlines were negatively related to perceived cohesion and positively related to perceived loafing. The impact of sociodemographic faultlines on team functioning was less detrimental when leaders held strong diversity beliefs. Against our expectations, we found no support for an impact of experience-based faultlines on perceived cohesion or a moderating role of leaders’ diversity beliefs in this context. Potential explanations for these results and implications for organizations and team leaders are discussed.
The skill shortage is becoming an ever-increasing challenge for IT departments. Allocation of resources in the best possible way is even more important. The challenge is to improve the enterprise not only on the side of the organizational and process level, but to develop new strategies and approaches in human resource management. Only a symbiosis of the disciplines economics, psychology and information technology will enable relevant and indispensable employees and promote loyalty to the company. A frequent change of the work place, for a well-trained professional, is so long associated with normality until they find the best environment for fulfilling their needs and expectations. These expectations are no longer just on a financial level. This paper will analyse the previous work on these topics and demonstrate first conclusions regarding a way forward.
This essay develops an entrepreneur-oriented theory of risk-taking and innovation that is used to examine the different leadership styles of family business owners. This theory is based on the works of Schumpeter, who mainly focussed on the potential of supply in the competition for innovation, and the works of Hayek, who emphasized the importance of demand in this competition. By combining these two theories, a comprehensive understanding of economic innovation processes is presented. In the subsequent empirical section of the essay, these theoretical ideals of supply-oriented and demand-oriented innovators will be examined for what they look like in practice. Data from India and Japan is analysed in this explorative empirical research to examine the influence of cultural, social and legal norms on entrepreneurial risk-taking and innovation behaviour. The perspectives on “foreign cultures” expand our understanding of management in a way that encourages innovation- friendly entrepreneurship.
Das Studium der Rechtswissenschaften ist als eigenständiger Bestandteil in den meisten deutschen Studiengängen der Wirtschaftswissenschaft fest verankert. Der Aufsatz hat zum Ziel, die Inhalte und Lehrmethoden kritisch zu prüfen, die mehrheitlich in den juristischen Pflichtveranstaltungen im Wirtschaftsstudium verwendet werden. Sowohl Inhalte als auch Methoden der Lehre werden in der Regel aus der Ausbildung der Volljurist/innen übernommen. Ob aber Verfahren der Lehre, die für die Ausbildung von Jurist/innen entwickelt worden sind, uneingeschränkt auch für Wirtschaftswissenschaftler/innen geeignet sind, wurde im deutschsprachigen Raum bisher kaum diskutiert. Im Weiteren wird gezeigt, zu welchen Problemen die unreflektierte Übernahme von Lehrinhalten und Lehrmethoden ohne zielgruppengerechte Anpassung führt. Auf dieser Basis wird ein Vorschlag für die praxisorientierte Lehre rechtswissenschaftlicher Inhalte entwickelt. Es gilt, die in den Rechtswissenschaften bewährten Konzepte der Lehre den Bedürfnissen der Wirtschaftswissenschaftler/innen anzupassen und weiterzuentwickeln. Danach werden der rechtliche Lebenszyklus eines Unternehmens und Management-Fallstudien zu rechtlichen Problemen als didaktische Modelle vorgestellt und praktische Fragen der Lehre diskutiert. Ziel ist es, die Studierenden für die rechtlichen Probleme zu sensibilisieren, die in der betrieblichen Praxis von Bedeutung sind, und ihnen Kompetenzen zu vermitteln, mit deren Hilfe sie die in ihrem späteren beruflichen Alltag auftretenden Probleme erfolgreich bewältigen können.
The aim of this study is to carry out an economic analysis of the consequences that arose following the decriminalization of the issuance of bad checks in Turkey. In our statistical analysis we examined the legal situation of bouncing checks in three periods: before 2009 when the issuance of bad checks was subject to imprisonment, between 2009-2012 when a partial decriminalization took place and between 2012-2014 when the issuance of bouncing checks was fully decriminalized and penalties were reduced to only administrative fines. We test the hypotheses that partial or full decriminalization led to a rise in the number of bad checks in Turkey. We find that there is no statistical evidence for an association between the first, modest step of the decriminalization process (Law No. 5941) and the frequency with which checks bounced in Turkey. However, full decriminalization of bouncing checks (Law No. 6273) led to an increase in the frequency of bad checks. We also find that the establishment of a Risk Center by the Bank Association of Turkey helped to identify customers not worthy of credit and was successful in decreasing the frequency of bad checks. We conclude that in the case of Turkish check law imprisonment was more effective in deterring writers of bad checks than the administrative and civil sanctions that are now in place. Nonetheless, private credit screening efforts also promoted the targeted policy goal of limiting the number of bad checks in Turkey.

Organisations, Individuals as Employees, Individuals as Consumers and the Relationships Between Them
(2014)
Organisations of all shapes and sizes face a significant number of challenges that they must meet if they are to thrive in today’s globally hypercompetitive environment. Our aim is to help them deal with some of the most critical. An organisation is a collection of individuals working together in a structured way to achieve certain goals, and this understanding is central to our research interests. We aim to provide insights on current and emergent issues related to the three interconnected themes we focus on:
● the relationship between the individual as an employee and the organisation
● the relationship between the individual as a consumer and the organisation
● the relationship between the individual and the digitalised world.
The recommendations that flow from our research all have in common that they are corporately socially responsible. Our framework is based on CSR, sustainability and an ethical approach.
Reputationsmanagement
(2015)
Anabel Ternès und Christopher Runge zeigen am Beispiel Medical Care, dass es sich auszahlt, in eine hohe Reputation zu investieren. Unternehmen mit einem guten Ansehen können höhere Preise verlangen, Kunden gewinnen und binden, die besten Mitarbeiter für sich gewinnen und insbesondere in Krisenzeiten von ihrer Reputation als immateriellem Wert als Wettbewerbsvorteil zehren. Voraussetzung hierfür ist ein systematisches, professionell begleitetes Reputationsmanagement, das gewährleistet, in Zukunft zu agieren statt nur zu reagieren. Gutes Reputationsmanagement erfordert einzelne, aufeinander abgestimmte Schritte, die sich gegenseitig perfekt ergänzen – zum Aufbau, zum Erhalt und zur Verbesserung einer positiven Unternehmensreputation.
Die Digitalisierung, Globalisierung und der demographische Wandel verstärken bestehende Diskrepanzen zwischen dem Vertrieb und anderen Unternehmensbereichen. Eine marktgerechte und wertorientierte Ausrichtung des Vertriebs kann hier unterstützen. Zielführend ist allerdings ein konsequentes Schnittstellenmanagement, das die enormen Informationsmengen und -geschwindigkeiten beherrscht.
Anabel Ternès, Ian Towers und Marc Jerusel gehen der Frage nach, welche neuen Konsummuster sich aufbauend auf den Begriffen Individualisierung und Nachhaltigkeit herausbilden könnten. Denn der Trend nach nachhaltigen und individualisierten Produkten ist bereits seit mehreren Jahren spürbar, gilt jedoch weiterhin als Trend für den Privatkonsum der kommenden Jahre. Im Bereich Individualisierung erläutern die AutorInnen dafür zum Beispiel das Produktionsprinzip der Mass Customization. Nachhaltig Denkende versuchen dagegen, bewusste Konsumentscheidungen zu treffen.
Metamorphose für Verkäufer
(2015)
Für einen nachhaltigen Erfolg im Vertrieb sind neue Qualitäten notwendig: weniger Rhetorik — mehr Empathie, weniger Produktpräsentation — mehr Entwicklung von individuellen Lösungen, weniger Verkäufer — mehr Berater. Denn der Kunde von heute ist anspruchsvoller als früher, er ist gut informiert und nimmt sein Recht auf umfassenden Service wahr.
Anabel Ternès, Ian Towers und Marc Jerusel widmen sich der Frage, welche Konsummuster den Privatkonsum im Deutschland der kommenden zehn Jahren verändern werden. Dabei wird auf bereits absehbare Konsumtrends wie zum Beispiel E- und M-Commerce sowie Connected Retail Bezug genommen. Im Vordergrund stehen die Auswirkungen der Digitalisierung auf den stationären Handel und die Konsumenten. Die AutorInnen stellen u.a. dar, dass eine der zentralen Herausforderungen darin liegen wird, sich der Digitalisierung proaktiv zu stellen, um das Konsumerlebnis der Verbraucher zu verbessern. Doch auch die Grenzen des Onlinehandels werden aufgezeigt.
Interactions among people have substantially changed since the emergence of social networks, the expansion of the Internet and the proliferation of connected mobile devices, and so have the possibilities of collaborative learning, with the inclusion of new e-learning platforms. From this point, assessing human knowledge in these virtual environments is not a trivial task. This work presents a novel cloud-computing-based service which relies on advanced artificial intelligence mechanisms to infer knowledge and interest from users considering the aggregated data presented from/to these users in different social networks. This way it is possible to assess with a certain degree of confidence the user knowledge level in different topics as well as recommend additional specific education related to his/her former studies in order to get a better/desired job.

The reporting of Corporate Social Responsibility (CSR) in hotels plays a crucial role in the assessment of their sustainability activities. Research shows, that if the CSR commitment of hotels is interpreted by guests as a real public interest, CSR has a positive impact on brand evaluation as well as on guest satisfaction. However, the sustainability efforts of hotels are often perceived as pure self-interest and the charge of greenwashing is in the air. Thus, standards in CSR reporting are urgently required. In hospitality so far, neither guidelines for CSR reporting nor third party monitoring organizations exist so far. This paper presents a six-step framework encouraging bilateral sustainability communication in the hotel industry. The common method to proclaim sustainability via reports or websites is typically one-directional from the hotel to the guest (typically referred to as signalling approach). In the long run, this is not enough. Thus, the other direction (typically referred to as screening approach), should particularly be considered as well. Screening is achieved through the use of user generated content (UGC) and electronic word of mouth (eWOM) via evaluation platforms, which nowadays enjoy wide acceptance by guests.
In the presented framework, CSR reporting and CSR rating are outsourced to the guest and the corresponding crowd. This procedure includes several advantages for hotels. First, the efforts and costs of CSR reporting are reduced. Second, the general public is used as a third-party control mechanism for the CSR reporting (typically referred to as monitoring approach). Finally, following this monitoring aspect, the perceived credibility of the CSR reporting in turn will be higher.
Since the credibility and reputation of eWOM largely depend on the number of existing reviews, it is important to generate sustainability-oriented eWOM and to utilize guests for CSR reporting issues. Therefore, based on the well-known phases of service marketing, a five-step-approach is integrated in the framework.
This paper aims to present a solution that enables organizations to monitor and analyse the performance of their business processes by means of Big Data technology. Business process improvement can drastically influence in the profit of corporations and helps them to remain viable. However, the use of traditional Business Intelligence systems is not sufficient to meet today's business needs. They normally are business domain-specific and have not been sufficiently process-aware to support the needs of process improvement-type activities, especially on large and complex supply chains, where it entails integrating, monitoring and analysing a vast amount of dispersed event logs, with no structure, and produced on a variety of heterogeneous environments. This paper tackles this variability by devising different Big Data based approaches that aim to gain visibility into process performance.
