Struktur und Entwicklung der Controllingforschung — Eine Zitations-und Kozitationsanalyse von Controllingbeiträgen in deutschsprachigen wissenschaftlichen Zeitschriften von 1970 bis 2003

Zusammenfassung  Controlling ist eine vergleichsweise junge Teildisziplin der Betriebswirtschaftslehre, die sich mittlerweile in Praxis und Wissenschaft etabliert hat. Das Wissen über seine Entwicklung ist in weiten Teilen noch unscharf und weitgehend durch „anecdotal evidence” bestimmt. Die Autoren verfolgen daher in ihrem Aufsatz das Ziel, einen Beitrag zum besseren Verst?ndnis der Strukturen und Entwicklung der deutschsprachigen Controllingforschung zu leisten. Hierfür analysieren sie die Zitations-und Kozitationsstrukturen in 643 Beitr?gen zu Controllingthemen, die im Zeitraum von 1970 bis 2003 in sechs führenden wissenschaftlichen Zeitschriften im deutschen Sprachraum ver?ffentlicht wurden. Diese Beitr?ge enthalten insgesamt 18.125 Quellen. Im Ergebnis der Analysen zeigt sich, dass das Zitierverhalten in der Controllingforschung im Vergleich zu anderen betriebswirtschaftlichen Teildisziplinen durch eine Reihe von Besonderheiten gepr?gt ist und dass sich die Strukturen der deutschsprachigen Controllingforschung über die Zeit stark ver?ndert haben.

Structure and development of research on controlling — a citation analysis papers on controlling in German speaking journals from 1970 through 2003

Summary  Controlling is a relatively young discipline in the field of business administration, which has now established itself in practice as well as in theory. Our knowledge about its development is for the most part still diffuse and dominated by anecdotal evidence. In their paper, the authors pursue the goal of contributing to a better understanding of the structures and the development of the German-speaking research in controlling. For this purpose, they analyze the citations-and co-citations structures of 643 articles, focusing on controlling aspects published in six leading Germanic academic journals between 1970 and 2003. These papers comprise a total of 18,125 sources. The results of the analyses show that the attitude to cite in controlling research, compared to other disciplines in business administration, is characterized by a number of features. Furthermore, the structures of German controlling research have changed significantly over time.

     

Portfolio optimization: New capabilities and future methods

Summary  This paper addresses the problem of portfolio selection in finance. In many cases, currently available software to compute the efficient frontier runs into difficulty in problems with more than about 600 securities. To proceed beyond this size, it is often necessary to modify the problem in which case there is typically a loss of information. In this paper, we discuss a computer capability that can exactly compute mean-variance efficient frontiers of problems with up to 2,000 securities in very reasonable time (even if a problem’s covariance matrix is 100% dense). The paper also discusses an augmentation to the theory of portfolio selection that allows multiple objectives (such as dividends, liquidity, social responsibility, amount invested in R&D, and so forth) to be incorporated into the portfolio selection process. In such problems, the efficient set is no longer a “frontier,” but is now best described as a “surface” with the interesting property that it is composed of platelets (like on the back of a turtle). Moreover, the computer capability that can compute the exact efficient frontier of a mean-variance problem with up to 2,000 securities also has, after additional coding, the ability to compute exactly all platelets of the efficient surface of a tri-criterion portfolio problem with up to 400 securities.

Zusammenfassung  In dieser Arbeit stellen wir einen leistungsf?higen Rechenalgorithmus vor, um den effizienten Rand (die nichtdominierten Alternativen) von Portfolio-Auswahlproblemen in der Finanzierung zu bestimmen. Wir bezeichnen den Berechnungsalgorithmus, der in Java programmiert ist, mit MPQ (multi-parametric quadratic programming). MPQ weist gegenüber bisherigen Berechnungsverfahren eine Reihe von Vorteilen auf: Es kann für umfangreiche Anwendungsf?lle genutzt werden, ist durch passable Rechenzeiten charakterisiert und kann die Menge effizienter Alternativen in einem Bruchteil bisher üblicher Rechenzeiten bestimmen.

     

Mehrperiodige Bewertung mit dem Tax-CAPM und Kapitalkostenkonzept

Zusammenfassung  Aus der Empfehlung des IDW, die für die Unternehmensbewertung mittels der DCF-Verfahren erforderlichen Kapitalkosten aus dem einperiodigen Tax-CAPM abzuleiten, ergibt sich die Notwendigkeit, dieses Modell mehrperiodig anzuwenden. Sowohl die hierzu erforderlichen Pr?missen als auch die Struktur der aus der mehrperiodigen Anwendung resultierenden Bewertungsgleichungen sind bislang ungekl?rt. Der vorliegende Beitrag spezifiziert ein mehrperiodiges Tax-CAPM, welches zur Bewertung mehrperiodiger stochastischer Cash-Flows bei differenzierter Besteuerung von Zinsen, Dividenden und Wert?nderungen eingesetzt werden kann. Die aus der Anwendung dieses Modells resultierenden Bewertungsgleichungen erm?glichen die Abbildung sowohl des Risikos als auch der Besteuerung einer durch den Kapitalmarkt bestimmten Alternativanlage mittels deterministischer Diskontierungsfaktoren, welche die Kapitalkosten der zu bewertenden Cash-Flows darstellen. Unter den restriktiven Pr?missen des vorliegenden Modells ist es demnach m?glich, die Einkommensbesteuerung der Kapitalgeber konsistent in die DCF-Verfahren zu integrieren. Der Autor dankt zwei anonymen Gutachtern der ZfB für wertvolle Hinweise und Verbesserungsvorschl?ge.     

Trends in the association between educational attainment and class destinations in West Germany: Looking inside the service class

The paper investigates long-term trends in the association between educational attainment and class destinations in Germany. Most recent evidence for several European countries reveals a downward effect of education on social class. To test changes in the association in Germany I use the 1976–2007 waves of the German Microcensus (GMC), which is a nationally representative, repeated cross-sectional survey. For Germany, log-linear models indicate that the relationship between education and class destinations remains rather constant for both sexes. I also find that returns to higher education in access to service class positions do not consistently decline either. Only university graduates’ relative access chances slightly decreased in comparison to Abitur-holders from the 1980s to the 1990s. In order to consider compositional changes in the service class in more detail, I further disaggregate the service class into three types of employment: administrative/managerial positions, professional experts and professional positions in the social services. In fact, I find that access to administrative and managerial positions is less dependent on education than access to the professions. While professional positions in the social services become less stratified by education over time, it is compensated by a reverse development for professional experts. As substantially more employees work in administrative and managerial jobs since the 1970s, the slight reduction in university returns can indeed be attributed to a compositional effect. In spite of these qualitative and quantitative changes, the strong impact of education on access to the service class does not become blurred. The paper concludes that the persistent institutional framework in Germany does not lead to a decline in the overall association between educational attainment and class destinations.     

Mother–infant Interaction Quality and Infants' Ability to Encode Actions as Goal‐directed

The current study investigated the relationship between mother–child interaction quality and infants' ability to interpret actions as goal‐directed at 7 months in a sample of 37 dyads. Interaction quality was assessed in a free play interaction using two distinct methods: one assessed the overall affective quality (emotional availability), and one focused on the mother's proclivity to treat her infant as an intentional agent (mind‐mindedness). Furthermore, infants' ability to interpret human actions as goal‐directed was assessed. Analyses revealed that only maternal emotional availability, and not maternal mind‐mindedness, was related to infants' goal‐encoding ability. This link remained stable even when controlling for child temperament, working memory, and maternal education. These findings provide first evidence that emotionally available caregiving promotes social‐cognitive development in preverbal infants.     

The new ‘sustainable communitarian’ logging schemes and their critique inside multiple-use conservation areas in the Brazilian Amazon: preliminary notes

Deforestation has risen sharply in Brazil since 2012, and conservation areas are facing increased pressure. This article studies the rise of so-called ‘sustainable’, ‘communitarian’, and/or ‘cooperative’ logging schemes inside multiple-use conservation areas in the Amazon. The findings, based on fresh field research in Acre and Pará, reveal conflicts, problems, and risks associated with logging schemes, although they are portrayed in the international timber trade as certified and socio-environmentally sustainable solutions that help conservation. However, the expansion of logging presents a danger for curtailing forest degradation, fires, and corruption that is linked to the fast returns from sale of timber, especially inside conservation areas that have been mostly intact until now. There is an urgent need to change the strategy of promoting logging as a key source of income for forest-dwellers, and a need to change the policies allowing the expansion of ‘sustainable logging’.     

Kooperation unter Konkurrenten? Regionale Kulturmuster und soziale Praktiken betriebsübergreifender Personalwirtschaft

During the recent financial and economic crisis, trade unions and employers’ associations have increasingly concluded collective agreements on so-called “collegial temporary work” that enables flexible deployment of employees, especially for small and medium sized enterprises. Empirical results show large differences in the application of those collective agreements: While the possibilities of the agreements were sometimes actively used in some regions, companies in other regions avoided implementation – despite their potential to cope with important challenges of economic crises and skill shortages. The paper selects a structuration theory perspective to analyze the reasons for the differences in the practice of this human resource management strategy by comparing two German regions (Braunschweig and the Ruhr area). The differences in the practices can be traced back to regional cultural patterns, interests of key actors, and the degree of involvement during the implementation period.     

Slug grazing effects on seedling and adult life stages of North American Prairie plants used in designed urban landscapes

Designed vegetation is a major contributor to ecosystem service provision in cities, and as such the study of how herbivory and other ecological factors determine its capacity to deliver such services, is long overdue. This study investigated the effect of slug grazing on the establishment and development of 26 species of North American prairie forbs and grasses used in sown or planted naturalistic communities in urban greenspace. The experiment was designed to provide slugs with the opportunity to choose between the plant species used, to mirror the situation that prevails in public greenspace. Slug density was manipulated through baiting with metaldehyde at different frequencies. Seedlings of prairie species were more palatable to slugs than adults. Seedling establishment was significantly reduced in most species by slug grazing, with only seven species showing no significant increase in establishment in response to baiting with metaldehyde. In many species successful establishment was based on moderate-high unpalatability and large or fast growing seedlings. Adult prairie plants were typically more able to withstand slug damage, and once their shoots reached a certain size, grazing declined. This was not true of the most palatable species, which even as adults were eventually eliminated by grazing in the absence of baiting. Phenology plays an important role in the survival of adults, with early emerging species potentially subject to severe damage due to the limited availability of alternate food plants. As a group, prairie forbs are typically palatable to slugs, and unlikely to be persistent in the most slug-rich urban situations.     

Dispositions to Act in Favor of the Environment: Fatalism and Readiness to Make Sacrifices in a Cross‐National Perspective1

This article hypothesizes that individuals’ environmental attitudes depend not only on their knowledge, interests, emotions, and values but also on the social context in which they live. We test this hypothesis by analyzing the 2000/01 ISSP‐II Survey on Environmental Attitudes; the data include respondents from 23 countries. Our findings show that individual characteristics influence both “pessimistic environmental orientations” and “the willingness to act in favor of the environment.” As for social context, the level of development and affluence, the degree of political centralization, the presence of green movements and parties, and the degree of objective pollution in a country are all important. However, their influences on fatalism and willingness vary.
