Small-scale farmers’ coping strategies to extreme weather events in Upper Guinea
(2023-03-06)
Extreme weather events pose a serious threat to subsistence farming and food security in Upper Guinea, where most farmers rely heavily on rain-fed agriculture. Following crop failures, farmers use what is available to them to try to maintain household food security. This paper investigated the coping strategies chosen by farmers in Upper Guinea and the motivating factors behind them. A multistage sampling method was used to select a purposive random sample of 1,500 farm households within nine selected livelihood zones ...

Practical application of active premagnetization in transformerless DC/DC converters
(2023-05-17)
Magnetic devices are used in almost every power electronic system. Therefore, their purpose and with that their requirements can vary in a wide range. The consequence is a large number of options regarding the priority of optimisation. In this work, the focus is on reducing the volume or weight of inductors in transformerless DC-DC converters. Active prmeagnetization is choosed as an optimisation approach. The technique enables an operation of the DC-DC-converter in the Triangular Current Mode (TCM), whereby ...

Does Political Resource Curse Really Exist? Evidence from the Rentier States in the Greater Middle East
(2023)
This Extractivism Policy Brief shows:
• Oil rents may affect the political regimes through influencing both defense and non-defense expenditures.
• Defense expenditures are considerably influenced by oil rents fluctuations and the quality of political system.
• The rent-seeking by incumbent autocrats may take the form of misappropriation of government revenues away from public services towards patronage.
• Being a ‘political curse’, natural resources could be detrimental to democracy and enhance regime ...

Fabrication and Investigation of Diamond Membranes for Photonic Nanostructures
(2023)
Due to its exceptional physical and chemical characteristics, diamond in a form of thin membranes is a particularly promising material for the fabrication of high-quality photonic devices. Especially for envisioned applications in quantum information technologies and communication, diamond gained, as a host material, an ever-increasing scientific interest based on remarkable properties of different color centers in its crystal lattice, e.g. nitrogen-vacancy centers, serving as single-photon emitters. As a high index ...

Environmental Tax Reform in Latin America
(2023)
• Latin American countries need to implement an agenda of green tax reforms to adapt their current development path and better respond to climate change. The decarbonization of the energy matrix is essential to mitigate future challenges.
• These governments have the potential to raise environmentally oriented taxes to generate additional revenues. Objective should be to adapt to the energy transition, attenuate extractivism and promote better income distribution and growth.
• The design and implementation of green ...

Verfassungsrechtliche Analyse der Modernisierung des Besteuerungsverfahrens
(2023)
Große Teile des „Gesetz[es] zur Modernisierung des Besteuerungsverfahrens“ traten am 1. Januar 2017 in Kraft. Mit diesem Gesetz wollte der Gesetzgeber eine Zeitenwende im steuerlichen Verfahrensrecht einläuten, indem er die seit langem in der Verwaltungspraxis verwendete Möglichkeit, Verwaltungsakte ausschließlich automationsgestützt zu erlassen, erstmals gesetzlich regelte. Kernstück dieses Gesetzgebungspaketes ist die erstmalige gesetzliche Regelung eines Risikomanagementsystems zur Prüfung von Steuererklärungen.

Characterisation of Cold Asphalt Mixtures with the Addition of Active Fillers
(2023)
Climate change, the limited availability of natural resources, and energy crises are putting pressure on the global societies? to employ low-energy and low-emission technologies for road pavement construction. Cold Recycled Materials (CRM) is an efficient and low-impact solution. CRM with Bituminous Emulsion (CRM-BE) is one of the most common types of CRM. CRM-BEs are created at ambient temperature by combining a high amount of Reclaimed Asphalt (RA) with Bitumen Emulsion (BE). BE used in CRM is typically composed ...

Capital Accumulation, Sector Productivity, and Economic Growth
(2023)
This dissertation is motivated by the research results of Benigno and Fornaro (2014). Benigno and Fornaro (2014) research, how low interest rates impact the productivity of economies.
This dissertation implements extensions of the Benigno and Fornaro (2014) model, that particularly address the capital accumulation, the production functions, and the technology accumulation. In doing so, this dissertation shows that some of the Benigno und Fornaro (2014) research results require specific assumptions, to qualitatively ...
