Eine soziologische Systemanalyse und sozio-ökonomisches Review der Soziotechnik Energiewende

The transition of the energy supply system in Germany from fossil-nuclear energy resources to renewable energies is a policy issue and defines a society technics. Society technics takes responsibility for an essential societal need and should be based on an agreement between all actors in all involved systems. According to a society-technics there are benefits for encouraging research, good governance for political support, public understanding of science (PUSH), and academic consultation for politics.Positive implementation will results in optimal coordination as all systems will function and all actors will work for synergy-effects. But a sociological system analyses works out many “dyssynergies”, handling the transition only as technological challenges and failing in underlying this transformation as a socio-technical system. Using renewable energies will not only change the technological system architecture but also modifying social systems and individual attitudes.     

New Zealand secondary technology teachers’ perceptions: “technological” or “technical” thinking?

Technology education in the New Zealand context has seen significant change since it’s inception as a technical subject. The changing nature of the subject in New Zealand secondary schools is influenced by some teachers’ preoccupation with the making of quality product outcomes, rather than their enactment of the curriculum, which conceptualises a wider remit. Research into the perceptions of technology teachers’ interpretation and enactment of the curriculum suggests that to enable change, teachers need to adopt a form of “technological thinking”, in support of their “technical thinking”. Technological thinking is a notion presented to support teachers to explore a range of differing pedagogical approaches and learning outcomes, reflective of the intent of the New Zealand curriculum, which aims to foster learning environments that are innovative and responsive to students’ social and academic needs.     

Back to Basics: Remittances in the Keynesian Macroeconomic Framework

This paper examines a remittance multiplier based on the short-run Keynesian equilibrium approach and shows how income may be affected by remittance inflows. We explore this through the equilibrium in the goods and money markets, where remittances can affect both consumption and the demand for real money balances. We present this simple theoretical model utilizing a standard Keynesian framework. The short-run Keynesian equilibrium approach provides insight into how remittances affect output and income, and its potential multiplier effects. The model used is indicative of a positive relationship between the marginal propensity to consume out of remittances and the multiplier. The framework also shows that remittances will have a greater impact if its marginal propensity to consume is greater than that for standard disposable income.     

Cuba,Trade Dependency and the GATT/WTO System

Cuba sought economic independence from the U.S. and its reliance on sugar exports after its 1959 revolution, but subsequently developed new dependency relationships. In the meantime, Cuba remained inside the General Agreement on Tariffs and Trade (GATT), despite conducting most of its trade outside it. This paper explores the political economy of Cuba’s participation in the GATT and later the World Trade Organization (WTO). Documents show that Cuba sought to use its participation to gain new markets and influence in the developing world. While Cuba has gained little economically from its participation, in recent years it has diversified its exports and trade partners, and its trade interests now align more closely with WTO rules. Economic reforms will be necessary in order for Cuba to benefit.     

Corruption and Its Effects on FDI: Analysing the Interaction Between the Corruption Levels of the Home and Host Countries and Its Effects at the Decision-Making Level

This study furthers our understanding of how corruption affects the decision-making process of allocating foreign direct investment. Drawing on the responses of 28 managers in charge of establishing operations in a highly corrupt host country, we argue that those firms based in home countries with low levels of corruption are more proactive in preparing to face corruption abroad than those based in countries with high corruption levels. This means that firms from less corrupt home countries have strategies in place to deal with high corruption abroad. This finding is based on the fact that these firms have stronger pressures to not engage in corruption from their home stakeholders. Also, these firms might not have the experience of dealing with corruption at home, which hinders their potential to deal with corruption abroad. On the other hand, those firms based in highly corrupt home countries do not have clear strategies to deal with corruption abroad. This assertion is based on the fact that these firms might have familiarity in dealing with corruption and thus, might not see it as an obstacle to operating abroad.     

Stochastic non-smooth envelopment of data for multi-dimensional output

The proposed method of Stochastic Non-smooth Envelopment of Data (StoNED) for measuring efficiency has to date mainly found application in the analysis of production systems which have exactly one output. Therefore, the objective of this paper is to examine the applicability of StoNED when a ray production function models a production technology with multi-dimensional input and output. In addition to a general analysis of properties required by a ray production function for StoNED to be applicable, we conduct a Monte Carlo simulation in order to evaluate the quality of the frontier and efficiencies estimated by StoNED. The results are compared with those derived via Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA). We show that StoNED provides competitive estimates in regard to other methods and especially in regard to the real functional form and efficiency.     

Modularization of hybrid censoring schemes and its application to unified progressive hybrid censoring

In this paper, a structural analysis of hybrid censoring models is presented. This new modularization approach to hybrid censoring models enables a convenient derivation of distributional results. For instance, it allows to derive the exact distribution of the MLEs under an exponential assumption for very complex hybrid scenarios. In order to illustrate the benefit of this idea, we apply it to four new unified progressive hybrid censoring schemes. They are extensions of already proposed unified Type-I/II/III/IV hybrid censoring schemes to progressively Type-II censored data. The resulting analysis shows that the modularization approach provides a powerful, efficient, and elegant tool to study even more complex hybrid censoring models.     

Smart Meter-Angebote: Eine empirische Untersuchung von Kundenpräferenzen

The implementation of smart meters in German households by 2032 is a major step in the transition towards an intelligent and connected energy system. Despite of federal legislation providing a structured plan for the nationwide smart meter rollout including basic product requirements, actors within the energy market have the opportunity to take an active part in shaping the market through appealing product offers and hence to create competitive advantage. This study identifies relevant features of smart meters from literature und business practice, and measures customer’s preferences for these features. Results indicate predominantly positive customer evaluations of smart meter features, amongst which the availability of consumption data, the installation price and rental charges as well as time variable tariffs contribute most to overall utility of smart meters. Finally, findings suggest targeting customers by defining strategies to address privacy concerns, to educate about saving potentials as well as to create differentiated pricing schemes.
