The Rumours of the Dollar's Death are Much Exaggerated北大核心CSSCISSCI

It is the season of dollar panic.These panic-mongers are varied: goldbugs, fiscal hawks and many others agree that the dollar, the dominant currency since the first world war, is on itsdeath bed. Hyperinflationary collapse     

Development of onshore wind energy utilisation in Germany

Onshore wind energy utilisation in Germany has developed very dynamically in the last decade. This has mainly been driven by the renewable energy laws that systematically support the expansion of renewable energy in the electricity sector. In 2009 a revised law with increased feed-in tariffs for wind energy has come into force. Existing studies already predict a wide range of development patterns under the Renewable Energy Sources Acts 2000 and 2004. This paper investigates the long term impact of different feed-in tariffs implemented by the legislative authorities and it provides corresponding future development patterns of onshore wind energy utilisation in Germany. The underlying System Dynamics model considers technical as well as economic conditions and constraints. The approach and the model’s results are contrasted with other published predictions qualitatively and quantitatively. This comparison shows that the model’s outcome lies in the range of predictions by existing studies, but also shows some interesting differences.

Zusammenfassung  Die Entwicklung der Windenergienutzung in Deutschland wahrend der letzten Dekade verlief sehr dynamisch. MagBgeblich dafur war die systematische Forde-rung mittels der Erneuerbare Energien Gesetze (EEG) bzw. deren Vorlaufer. Vom Jahr 2009 an gilt ein uberarbeitetes Gesetz, welches u.a. erhohte Einspeisever-gutungen furWindenergie beinhaltet.Vorliegende Studien, die sich mit derzu-kunftigen Entwicklung auseinandersetzten, zeigen bereits deutlich unterschied-liche Szenarien fur die Entwicklung unter dem EEG 2000 und 2004. Diese Arbeit setzt sich mit den langfristigen Auswirkungen der verschiedenen vom Gesetz-geber festgelegten Einspeisetarife auseinander und stellt entsprechend unter-schiedliche Ausbauszenarien fur die deutsche Onshore Windenergienutzung dar. Das zugrunde liegende System Dynamics Modell berucksichtigt dabei sowohl technische als auch okonomische Parameter. Der Ansatz sowie die Ergebnisse werden anderen veroffentlichten Prognosen gegenubergestellt. Die Ergebnisse liegen innerhalb der Spannbreite der anderen berucksichtigten Studien, zei-gen jedoch auch interessante Unterschiede.

     

Innovativer Energiespeicher Bundeswasserstraßen

The present analysis provides a contribution to the question of how a system integration of large-scale energy storages can be implemented. It is to be investigated if and how federal waterways can be used for this purpose. Initially, a baseline study was carried out in which the federal waterways are systematically assessed with regard to their suitability for/as energy storage systems. Apart from the technical and the hydro mechanical implementation of the storage process, the advantages and disadvantages of the federal waterways in comparison to conventional pump storage stations play a significant role. A presentation and classification of the potentially available canal sections provides an overview of the suitable storage systems of the federal waterways. A specifically designed storage simulation on the basis of a sample application is used, in order to determine the capacity of the canal system for energy storage. Consequently, the simulation showed the theoretical capability of the federal waterways as energy storage systems, through their ability to balance the load and temporal fluctuations of the energy input. The simulation program Matlab was used on the basis of the synthetic load and delivery profiles. Finally, based on the example of the ships lock in Uelzen and the Scharnebeck boats lift, a simulation of the possible re-equipping options will be described, technically abstracted, economically analysed and combined with renewable energy facilities within a virtual power plant. The detailed formulation of further approaches and the calculation of possible application scenarios play a central role within this analysis.     

The impact of stakeholder orientation on sustainability and cost prevalence in supplier selection decisions

The stakeholder approach has taken a prominent role in the discussion of sustainability measures at varying strategic levels and corporate functions. Literature on sustainability suggests that firms have to cope with enhanced pressure from different stakeholder groups regarding their upstream supply management practices. At the same time purchasing managers face the trade-off between sustainability and cost prevalence in selecting new suppliers. Thus, it is of major concern for companies in general and purchasing organizations in particular to know and understand how purchasing managers react to the influence of specific stakeholder groups when it comes to supplier selection decisions. Following this notion we formulate six sets of hypotheses linking the adoption of ethical business culture to the prevalence of sustainability and cost criteria in supplier selection decisions to be tested in a path analytical model.Based on the results of an empirical study conducted with purchasing managers from multi-national firms located in Germany, this paper makes two major contributions: first, it sheds light on direct effects of shareholder, public, and customer orientation on the evaluation of the outlined-trade off; second, it investigates the indirect effects by introducing the formalization of ethical culture as a mediating variable to assess the impact of the three kinds of shareholder orientation on the propensity to select suppliers based on their performance in terms of social and environmental criteria as well as cost performance.     

Career patterns of top management team members in five countries: an optimal matching analysis

This paper introduces optimal matching analysis (OMA) to the field of top management research. With this method, we develop six career patterns of top management team (TMT) members from five countries based on their international experience, organizational tenure and professional experience. The results provide strong support for the significance of these patterns, since each country (Denmark, Germany, Japan, the United Kingdom and the United States) shows one to four predominant career patterns of their managers and the occurrence of these patterns also differs significantly between the fields of activity within the TMT (chairperson, head of a division, primary activities and support activities).     

Towards a classification of marine wildlife crime: Marketing strategies to curtail illegal fishing,malicious acts,and waterway pollution

Much effort has been dedicated to fighting wildlife crime with modest results. This paper focuses on marine wildlife crime, which suffers from a certain level of neglect due to terrestrial bias (a predominant focus on land animals). Despite legislative and enforcement efforts, there has been little integration of marketing techniques to curtail marine wildlife crime. For these reasons, we set out to study current issues surrounding marine wildlife crime by conducting interviews with three experts in areas of marine education, research, and legislation. The interviews provide an overview of the threats to marine wildlife, aid in the development of a classification of marine wildlife crime, and provide strategies as to what marketing actions may be useful to reduce it.     

MARKET TRANSACTIONS IN THE NATIONAL ACCOUNTS

This paper explains the treatment of market and non-market transactions in the national accounts. Different possibilities of defining these two types of transactions are discussed, and it becomes evident that a strong restriction of national accounts to market transactions only cannot be seriously taken into consideration. On the other hand, a system of supplementary tables is proposed which shows the market and the non-market transactions as such. Examples of tables of this kind are presented for the Federal Republic of Germany.
