Grounded Theory und ihre bisherige Anwendung in der empirischen Controlling- und Rechnungswesenforschung

Zusammenfassung  Die Bildung von Forschungshypothesen ist zwar immer ein kreativer, sollte aber gleichzeitig kein unsystematischer Prozess sein. Im vorliegenden Artikel liegt der Fokus auf der Methodenunterstützung des Entdeckungszusammenhangs. Die Methode der Grounded Theory bietet einen Bezugsrahmen für qualitative empirische Studien, mit dem Theorien entwickelt werden, die aus dem Textmaterial zu begründen sind. Eine Literaturanalyse verdeutlicht, dass das Potenzial dieser Methode bisher in der Controlling- und Rechnungswesenforschung weitgehend ungenutzt bleibt. Anhand einer Diskussion empirischer Studien, welche auf die Methode zurückgreifen, werden Anwendungsm?glichkeiten der Grounded Theory für diese Disziplinen aufgezeigt.

Summary  Creating research hypotheses is always a creative but not necessarily an unsystematic process. In our study we introduce a method supporting the logic of discovery. The grounded theory approach provides a framework for a systematic development of theories emerging from empirical data. A literature review stresses that the potential of the method so far is unused in accounting research. The grounded theory approach is introduced to support empirical work within this research field. Options for an application of the method in accounting research are shown by the means of a discussion of empirical studies. Furthermore the reader gets hints for reference studies.

     

Temporal Hydrologic Alterations Coupled with Climate Variability and Drought for Transboundary River Basins

Climate change (CC) and drought episode impacts linked with anthropogenic pressure have become an increasing concern for policy makers and water resources managers. The current research presents a comprehensive methodology but simple approach for predicting the annual streamflow alteration based on drought indices and hydrological alteration indicators. This has been achieved depending on the evaluation of drought severity and CC impacts during the human intervention periods to separate the influence of climatic abnormality and measure the hydrologic deviations as a result of streamflow regulation configurations. As a representative case study, the Lesser Zab River Basin in northern Iraq has been chosen. In order to analyse the natural flow regime, 34 hydrological years of streamflow (1931–1965) prior to the main dam construction were assessed. The Indicators of Hydrologic Alteration (IHA) method has been applied to quantify the hydrological alterations of various flow characteristics. In addition, an easy approach for hydrological drought prediction in relatively small basins grounded on meteorological parameters during the early months of the hydrological year has been presented. The prediction was accomplished by implementing the one-dimensional drought examination and the reconnaissance drought index (RDI) for evaluating the severity of meteorological drought. The proposed methodology is founded on linear regression relations connecting the RDI of 3, 6, and 12 months and the streamflow drought index (SDI). The results are critical for circumstances where an early exploration of meteorological drought is obtainable. Outcomes assist water resources managers, engineers, policy makers and decision-makers responsible for mitigating the effects of CC.     

Some properties of the length of the shortest half

This paper discusses some properties of the length of the shortest half proposed by Rousseeuw and Leroy (1988) as a robust scale estimator.     

Einnahmen- und ausgabenseitige Multiplikatoren der deutschen Volkswirtschaft

Theoretically based on the Haavelmo theorem, this study analyses the economic effects that increasing public expenditure or reducing public income have on the gross domestic product of Germany, with the help of two medium-sized macro-econometric models, the RWI business cycle model and the Econometric Model of the German Economy. The major finding is that most of the public revenue multipliers are considerably lower than most of the public spending multipliers. However, both the dimension and the time course of the effects are a function of the specific kind of politico-economic measures taken by the government.     

Social networks and small business performance in West African border regions

This paper studies the links between economic performance and social networks in West Africa. Using data collected on 358 small-scale traders in five border markets, we show that social networks can be simultaneously a resource which positively contributes to labour market outcomes and a social burden that has a negative economic impact. Testing the effect of social networks between small traders and three categories of actors, we find that the most well-connected actors are also the most successful in terms of monthly profit. The effects of social networks are, however, dependent on the type of persons with whom traders are connected. We show that support received from state representatives and politicians is converted into economic performance, while the impact of law enforcement officers on the monthly profits of traders is not significant. We also find that interacting with traditional religious leaders has a negative effect on economic performance. Our work has two implications: Firstly, collecting data on social networks remains challenging due to endogeneity. Secondly, network-enhancing policies should aim at improving both the internal connectivity of economic actors at the local level and their external connectivity with the rest of the world.     

Ist die Katharsis-Theorie zu retten?

Catharsis theory is regarded as refuted. This widespread belief can be questioned for two reasons. First, most test films used in experimental studies do not meet the requirements of catharsis theory; second the social consequences of catharsis were not measured. Two films were produced for our experiment, one which meets the requirements of catharsis theory and should reduce aggressiveness and one which, according to alternative theories, should increase aggressiveness. A control group saw a neutral film. As dependent variables (a) level of general aggression, (b) aggressive inclinations in social situations, and (c) willingness to use aggressive stereotypes were measured. The film that was assumed to reduce aggressiveness increased aggressiveness even more than the film that was assumed to increase it. This surprising finding and its consequences are discussed.

Biomic river restoration: A new focus for river management

River management based solely on physical science has proven to be unsustainable and unsuccessful, evidenced by the fact that the problems this approach intended to solve (e.g., flood hazards, water scarcity, and channel instability) have not been solved and long‐term deterioration in river environments has reduced the capacity of rivers to continue meeting the needs of society. In response, there has been a paradigm shift in management over the past few decades, towards river restoration. But the ecological, morphological, and societal benefits of river restoration have, on the whole, been disappointing. We believe that this stems from the fact that restoration overrelies on the same physical analyses and approaches, with flowing water still regarded as the universally predominant driver of channel form and structural intervention seen as essential to influencing fluvial processes. We argue that if river restoration is to reverse long‐standing declines in river functions, it is necessary to recognize the influence of biology on river forms and processes and re‐envisage what it means to restore a river. This entails shifting the focus of river restoration from designing and constructing stable channels that mimic natural forms to reconnecting streams within balanced and healthy biomes, and so levering the power of biology to influence river processes. We define this new approach as biomic river restoration.     

Endogenous Property Rights in a Hold‐up Experiment

In a hold‐up experiment designed to test theoretical predictions following from Hart and deMeza and Lockwood regarding investment behavior, Sonnemans, Oosterbeek and Sloof (SOS) find only a partial confirmation of theory. According to SOS these deviations from standard theory can be explained by positive reciprocal behavior. In this paper, we replicate the experiment by SOS and add another group of treatments in which asset ownership is endogenized by auctioning off the assets. Our experiment shows that the results by SOS crucially depend on the ownership structure being exogenously assigned by the experimenter. We present experimental evidence that, by and large, corroborates the theoretical predictions made by Hart.
