Soziale Beziehungen in virtuellen kooperativen Lernszenarien

This paper focuses first on the importance of establishing and maintaining social relationships in computer supported cooperative learning (CSCL) scenarios. Furthermore, scales to measure the degree of social relationship building in CSCL-environments (Kreijns, 2004) are introduced based on the concept on sociable CSCL environments. These scales shall measure how far it is possible to build social relationships based on virtual learning platforms. Kreijns’ work, i.e. his concept of ‘sociability’ of virtual learning environments, is compared to own research on group based learning in virtual seminars (Schmidtmann, 2005) and examined in a small empirical study.     

Wirkungen des TV-Duells im Vorfeld der Bundestagswahl 2005 auf die Wahlentscheidung

During the election campaign to the German Federal Election 2005 the incumbent chancellor Gerhard Schröder and his challenger Angela Merkel met one another on the occasion of a televised debate, the so-called “TV-duel”. This debate was viewed by roughly one third of the German electorate. It is analyzed, whether the perception of the TV-duel winner has had an influence on the voting decision. In the empirical analyses special regard is given to the stability of the winner perception until election day and the influence of subjective expectations towards the debate performance of the candidates. The data analyzed were collected by means of a new interviewing technology via the television screen of the respondents. It is shown, that the winner perception was largely stable and only marginally influenced by the media coverage following the debate. Subjective expectations towards the debate performance of the candidates turn out to be of no importance for the voting decision. The effect of the winner perception on voting behaviour was mediated by changing candidate orientations.     

Gibt es die Generation Golf?

Florian Illies in his essay “Generation Golf” developed the thesis that traditional values are experiencing a revival among the generation born between 1965 and 1975. This thesis is read in the context of sociological theories of value change and empirically examined on the basis of time-series data. It can be shown, that “Generation Golf” as a clearly distinguished birth cohort with a specific value profile does indeed exist. Starting with “Generation Golf”, a process of averting from postmaterial values can be observed.     

Realisierung von Cross-Selling Potenzialen durch das Management von kundeninitiierten Kontakten

Existing research has not sufficiently addressed the question of how to cross-sell additional products and services to customers and what the behavioral consequences of cross-selling are. Moreover, these cross-selling-related questions have not been investigated in the context of customer-initiated contacts.The contribution of the paper is the empirical analysis of metrics which can be used to predict cross-selling success, e.g., in a call-center. The results show that two metrics, namely first contact resolution and reason for contact, significantly predict cross-selling success. Another contribution is the analysis of behavioral consequences. Here the results show that usage intensity significantly increases the time directly after the cross-selling took place but relapses to the original level within a few weeks.The results of the study can be used to derive managerial implications for managing and controlling cross-selling initiatives and for increasing and stabilizing cash-flows.     

How Social Relations and Structures can Produce Happiness and Unhappiness: An International Comparative Analysis

In this paper, subjective well being, as measured by survey questions on happiness and life satisfaction, is investigated from a sociological-comparative point of view. The central thesis is that happiness and satisfaction must be understood as the outcome of an interaction process between individual characteristics and aspirations on the one side, and social relations and macrosocial structures on the other side. A distinction is made between life satisfaction and happiness; the former is more seen as the outcome of an evaluation process including material and social aspirations and achievements, the latter as an outcome of positive experiences, particularly close personal relationships. The focus of this paper is on micro- and macrosocial conditions favouring or inhibiting the emergence of happiness and satisfaction. It is hypothesized that dense and good basic social relations, occupational involvement and success, sociocultural (religious and altruistic) orientations and participation are conducive to happiness and life satisfaction; the same should be true at the macrolevel for economic prosperity, relatively equal social structures, a well-established welfare state and political democracy. The latter conditions, however, should be more important for life satisfaction than for happiness. A comparative, multilevel regression analysis of happiness in 41 nations around the world is carried out (using the World Value Survey 1995–1997). Both our general assumption and most of the specific hypotheses could be confirmed. It turned very clearly that “happiness” and “life satisfaction” are two different concepts. It could be shown that microsocial embedding and sociocultural integration of a person are highly relevant for happiness. However, contrary to earlier studies, we find that macrosocial factors like the economic wealth of nation, the distribution of income, the extent of the welfare state and political freedom are also relevant, particularly for satisfaction. What counts most is the ability to cope with life, including subjective health and financial satisfaction, close social relations, and the economic perspectives for improvement in the future, both at the level of the individual and at that of the society. These abilities are certainly improved by favourable macrosocial conditions and institutions, such as a more equal income distribution, political democracy and a welfare state.     

The Impact of Complexity on Knowledge Transfer in Manufacturing Networks

Coordinating knowledge transfer within multi‐plant manufacturing networks is a challenging task. Using a computational model, we examine when it is beneficial to create production knowledge within a central unit, the “lead factory,” and transfer it to geographically dispersed plants. We demonstrate that the knowledge transfer generates a trade‐off between a positive cost‐saving effect due to fewer adaptations in each plant, and a negative transfer cost effect due to the costly knowledge transfer itself. The complexity of the production process moderates the performance implications of the knowledge transfer because it determines the relative strength of these two effects. For production processes with low complexity, knowledge transfer can engender superior network performance. Here, an optimal extent of knowledge transfer exists, and thus, a complete knowledge transfer is not performance maximizing. For production processes with medium and high levels of complexity, performance is reduced rather than enhanced through knowledge transfer so that it is optimal not to transfer any knowledge from the lead factory to the plants. While we analyze knowledge transfer within a manufacturing network, our results are transferable to other settings that consist of a knowledge sending and receiving unit.
