Toward the Green Economy: Assessing Countries' Green Power

The green power potential of a country is a central factor in the transformation to a green economy. This paper argues that green power will become a decisive factor for global change. Green power combines sustainability, innovation and power into one concept. By merging insights from political science, economics and innovation research, this paper develops a multidimensional, multilevel concept of green power that takes both resources and processes into account. A first empirical assessment of the current distribution of green power in global environmental governance shows that China and India, in particular, as well as Brazil and Costa Rica are catching up in clean technology and renewable energy. The European Union, Germany and the United States still dominate, but they are not fully maximizing their green power potential. In spite of their discursive power, the green power potential of the least developed countries is relatively small, making the jump toward a green economy unlikely

New Horizons for Germany's Africa Policy

This paper deals with Germany's new Africa policy. The Federal Ministry for Economic Cooperation and Development (BMZ) presented a new Africa concept in January 2017. The BMZ wants to counter the further marginalisation of Africa with inclusive and sustainable growth. Chancellor Angela Merkel will explain her new policy for Africa at the G20 summit in Hamburg in July 2017, in an attempt to gain the approval of the other G20 members for focused cooperation with Africa. The paper argues that it remains solely the duty of African states to take their development into their own hands. Cooperation can support this process, but it cannot assume what is each state's individual responsibility. The Marshall Plan with Africa aims to develop a joint agenda with the countries of Africa. Yet because the African countries did not participate in developing the concept, the plan derived so far is more of a plan for Africa, identifying which measures the BMZ would like to implement in order to contribute to sustainable and inclusive economic growth in Africa. Africa is becoming increasingly differentiated, and developing a joint strategy with individual countries or groups of countries that reflects the varying speeds at which changes are occurring would be a decisive step. The plan does not cover sufficient ground on this issue. In order to develop a coherent Africa concept for the German federal government, the participation of the most important ministries needs to be improved, and the chancellor needs to be in charge of the overall management. The paper concludes that Germany's Africa policy needs to be redesigned. The Marshall Plan has generated a shift, but it does not provide sufficient guidance to new horizons and away from the well-beaten track of traditional development cooperation. The departure to a new age that is defined by increased cooperation with democratic African countries which are capable of reform, and by a courageous and consistent stance in relation to non-democratic countries, has not yet taken place

Middle East - North Africa and the millennium development goals : implications for German development cooperation

          Closed-loop controlled combustion is a promising technique to improve the overall performance of internal combustion engines and Diesel engines in particular. In order for this technique to be implemented some form of feedback from the combustion process is required. The feedback signal is processed and from it combustionrelated parameters are computed. These parameters are then fed to a control process which drives a series of outputs (e.g. injection timing in Diesel engines) to control their values. This paper’s focus lies on the processing and computation that is needed on the feedback signal before this is ready to be fed to the control process as well as on the electronics necessary to support it. A number of feedback alternatives are briefly discussed and for one of them, the in-cylinder pressure sensor, the CA50 (crank angle in which the integrated heat release curve reaches its 50% value) and the IMEP (Indicated Mean Effective Pressure) are identified as two potential control variables. The hardware architecture of a system capable of calculating both of them on-line is proposed and necessary feasibility size and speed considerations are made by implementing critical blocks in VHDL targeting a flash-based Actel ProASIC3 automotive-grade FPGA

Preparation and characterization of calcium cobaltite for thermoelectric application

Abstract Starting powders of CaCO 3 with different Ca:Co ratio and three different sources of cobalt (II,III) oxide were mixed and calcined at 700-1100 o C. DTA/TG, mass changes, density, grain size distribution, phase composition were examined. It has been found that phase composition of the resulted product was dependent on calcination temperature and properties of starting cobalt oxide. Three stages of cobaltite formation were established: simultaneous decomposition of CaCO 3 with Ca 3 Co 4 O 9 formation (800-900 °C), decomposition of Ca 3 Co 4 O 9 and formation of Ca 3 Co 2 O 6 (about 950 °C) and the last stage at 1050°C was dependent on starting cation ratio and source of cobalt (II,III) oxide. It has been found that total decomposition of the previous phases was observed after calcinations at 1050 °C in the batches with Ca:Co=1:1 ratio if very pure Co 3 O 4 was used for preparation. Replacement of pure Co 3 O 4 by cobalt oxide contaminated by cobalt hydroxide lead to re-formation of Ca 3 Co 4 O 9 phase at 1050 °C in 1:1 batches. Residual Co 3 O 4 and CaO was always present in calcined specimens. It seems that prolonged heat treatment did not lead to better reaction degree

Treatment and management of primary antibody deficiency: German interdisciplinary evidence‐based consensus guideline

This evidence‐based clinical guideline provides consensus‐recommendations for the treatment and care of patients with primary antibody deficiencies (PADs). The guideline group comprised 20 clinical and scientific expert associations of the German, Swiss, and Austrian healthcare system and representatives of patients. Recommendations were based on results of a systematic literature search, data extraction, and evaluation of methodology and study quality in combination with the clinical expertise of the respective representatives. Consensus‐based recommendations were determined via nominal group technique. PADs are the largest clinically relevant group of primary immunodeficiencies. Most patients with PADs present with increased susceptibility to infections, however immune dysregulation, autoimmunity, and cancer affect a significant number of patients and may precede infections. This guideline therefore covers interdisciplinary clinical and therapeutic aspects of infectious (e.g., antibiotic prophylaxis, management of bronchiectasis) and non‐infectious manifestations (e.g., management of granulomatous disease, immune cytopenia). PADs are grouped into disease entities with definitive, probable, possible, or unlikely benefit of IgG‐replacement therapy. Summary and consensus‐recommendations are provided for treatment indication, dosing, routes of administration, and adverse events of IgG‐replacement therapy. Special aspects of concomitant impaired T‐cell function are highlighted as well as clinical data on selected monogenetic inborn errors of immunity formerly classified into PADs (APDS, CTLA‐4‐, and LRBA‐deficiency)
