This paper compares the recycling attitudes of consumers in Germany and Japan, based on our nationwide questionnaires. We analyzed consumption behavior as well as recycling behavior in narrow sense, becauseit is important to study the former to see how the supply of recycled materials is balanced with the demand, particularly in Japan which exports little recycled materials. Toilet paper was adopted as a specific good for study, because consumers have options of buying virgin products and recycled products. It was found that German households pay for waste collection specifically and have higher recycling rates than Japanese households. On the other hand, similar figures in German and Japanese consumers were observed with regard to consumption of recycled products. Their purchasing criteria and preference on virginand recycled products of toilet paper were examined by self-report and blind test with 2x 2 experimental design for toilet paper (German versus Japanese, virgin versus recycled). Blind test showed that people prefer domestic and virgin products in both countries. Half of respondents rating virgin products guessed that the products contained recycled material. For Japanese, the material of the sample toilet paper, made from virgin pulp, seems to be a more determining factor thanthe nationality of products, i.e. made in Japan. On the other hand, for Germans, the domestic nature seems to be a more dominant factor than the material, i.e. made from virgin material. Canonical discriminant analysis in conjunction with logistic regression based on self-reporting data detected the characters `multiplied', `appearance' and `brand' as major factors making the difference in preference between the two countries. The possible reasons causing the similarity and dissimilarity between the two countries are discussed with reference to the background history. [ABSTRACT FROM AUTHOR]

New inter-national and transnational complexities of economic and political relationships destabilize extant categories and units of analysis for studying trajectories of social change and explaining commonalities and differences of complex inequalities across countries. New insights on gender regime change emerge by shifting from a singular to a multi-scalar analytical frame. The paper argues that complex inequalities cannot be understood by studying a bounded geographic unit of analysis. Toward this end, the paper compares Germany and Japan in a world regional perspective, applying Walby's gender regime theory. Case comparisons of Germany and Japan not only reveal historical pathways of national developments, but also can show the benefits of a multi-scalar analytic in differentiating varieties and futures of gender regimes. An examination of the care economy shows why a multi-scalar analytic is critical for tracking the economic geographies of reproductive/care labor (both paid and unpaid). [ABSTRACT FROM AUTHOR]

Over the last five decades, there have been several phases of interest in the so-called hydrogen economy, stemming from the need for either energy security enhancement or climate change mitigation. None of these phases has been successful in terms of a major market development, mainly due to the lack of cost competitiveness and partially due to technology readiness challenges. Nevertheless, a new phase has begun very recently, which despite holding original objectives has the new motivation to be fully green, i.e. based on renewable energy. This new movement has already initiated bipartisan cooperation of some energy importing countries and those with abundant renewable energy resources and supporting infrastructure. One key challenge in this context is the diversity of pathways for the (national and international) export of non-electricity renewable energy. This poses another challenge, that is the need for an agnostic tool for comparing various supply chain pathways fairly while considering various techno-economic factors such as renewable energy sources, hydrogen production and conversion technologies, transport, and destination markets, along with all associated uncertainties. This paper addresses the above challenge by introducing a probabilistic decision analysis cycle methodology for evaluating various renewable energy supply chain pathways based on the hydrogen vector. The decision support tool is generic and can accommodate any kind of renewable chemical and fuel supply chain option. As a case study, we have investigated eight supply chain options composed of two electrolysers (alkaline and membrane) and four carrier options (compressed hydrogen, liquefied hydrogen, methanol, and ammonia) for export from Australian ports to three destinations in Singapore, Japan, and Germany. The results clearly show the complexity of decision making induced by multiple factors, and that the preferred supply chain combination (electrolyser technology, green energy carrier) in terms of least cost strongly depends on whether the expected levelized cost of hydrogen (ELCOH) or the expected levelized cost of energy (ELCOE) is used as a decision criterion. For instance, with ELCOH for the case study, under the given input parameters, the Ammonia combination with alkaline electrolysers (AE-NH 3) becomes the least-cost supply chain option for Singapore, Japan, and Germany with values of 8.60, 8.78 and 9.63 $/kgH 2 , respectively. This leaves liquid hydrogen (with alkaline electrolysers) as the second-best supply chain route, with ELCOH values of 9.05, 9.39 and 10.70 $/kgH 2 , respectively. However, with ELCOE, methanol (with alkaline electrolysers) becomes the preferred supply chain path for all destinations, and liquid hydrogen (with alkaline electrolysers) keeps its place as the second-best alternative.

• In this scenario, states vulnerable to impacts of climate change deploy solar geoengineering; the article provides insights into possible responses of a Great Power Bloc (Member of UN Security Council + Japan and Germany). • We investigate the differences of possible responses; esp. with regard to challenges linked to a "free-driver" dynamic. • Varying assumptions about international relations in 2040 substantially shape the responses by the different groups (between hegemonic & non-aligned approaches). • We explore prospects of multilateral governance of solar geoengineering and point to questions about the functioning and cohesion of alliances. The paper examines a scenario exercise concerning deployment of solar geoengineering by a small group of states that are particularly vulnerable to climate change. Two groups of participants were each asked to provide expert decision-making advice to an alliance comprising great powers, and to propose a political response to the deployment initiative. This paper discusses the initial governance proposals and examines differences and exchanges between the groups throughout the exercise. The two groups delivered distinct governance proposals. The differences, which were driven largely by divergent worldviews and assumptions about the geopolitical context, provide insights into the complexities of responses to "free-driving" the deployment of solar geoengineering, internal functioning and cohesion of coalitions, and interactions among multiple responses to climate change.

Abstract: Only three days after the beginning of the nuclear catastrophe in Fukushima, Japan, on 11 March 2011, the German government ordered 8 of the country''s 17 existing nuclear power plants (NPPs) to stop operating within a few days. In summer 2011 the government put forward a law – passed in parliament by a large majority – that calls for a complete nuclear phase-out by the end of 2022. These government actions were in contrast to its initial plans, laid out in fall 2010, to expand the lifetimes of the country''s NPPs. The immediate closure of 8 NPPs and the plans for a complete nuclear phase-out within little more than a decade, raised concerns about Germany''s ability to secure a stable supply of electricity. Some observers feared power supply shortages, increasing CO2-emissions and a need for Germany to become a net importer of electricity. Now – a little more than a year after the phase-out law entered into force – this paper examines these concerns using (a) recent statistical data on electricity production and demand in the first 15 months after the German government''s immediate reaction to the Fukushima accident and (b) reviews the most recent projections and scenarios by different stakeholders on how the German electricity system may develop until 2025, when NPPs will no longer be in operation. The paper finds that Germany has a realistic chance of fully replacing nuclear power with additional renewable electricity generation on an annual basis by 2025 or earlier, provided that several related challenges, e.g. expansion of the grids and provision of balancing power, can be solved successfully. Already in 2012 additional electricity generation from renewable energy sources in combination with a reduced domestic demand for electricity will likely fully compensate for the reduced power generation from the NPPs shut down in March 2011. If current political targets will be realised, Germany neither has to become a net electricity importer, nor will be unable to gradually reduce fossil fuel generated electricity. Whether the reduction in fossil fuel use will be sufficient to adequately contribute to national greenhouse gas mitigation targets significantly depends on an active policy to promote electricity savings, continuous efforts to increase the use of renewables and a higher share of natural gas (preferably used in combined heat and power plants) in fossil fuel power generation.

Graphical abstract Abstract In the photovoltaic (PV) industrial chain, polysilicon is the most vital product affecting the scale of the entire industry. Polysilicon trade holds the highest profit margin, and the technological developments among countries is unbalanced, promoting international trade among countries. Therefore, analysis of the international polysilicon trade is crucial for understanding the development of the global PV industry. In this paper, we use a social network analysis (SNA) method to study the structure of the global polysilicon trade network and each country's characteristics in the network based on international trade data from 2006 to 2016. Our results show that the network is very concentrated and shows an obvious core-periphery structure. The United States of America (USA), China, Germany and Japan are the most powerful countries in the trade network. We also find that the development of polysilicon trade can represent progress of the PV industry. [ABSTRACT FROM AUTHOR]

Abstract: This paper analyzes the existence of flights from stocks to bonds and vice versa. We propose a definition and a test for flight-to-quality, flight-from-quality and cross-asset contagion and examine their characteristics and effects for the financial system. The empirical analysis for eight developed countries including the US, the UK, Germany and Japan shows that flights exist and are a common feature in many crises episodes. Our findings also reveal that flights are not merely country-specific events but occur simultaneously across countries. This indicates that there is a link between the occurrence of flights and cross-country contagion. Moreover, we show that flights enhance the resiliency of the financial markets by providing diversification benefits in times when they are needed most. [Copyright &y& Elsevier]

Abstract: After 100years phenolic resins continue to be a prominent resin system with an impressive worldwide volume of nearly 6million tons/year. It is a ubiquitous adhesive for a diverse spectrum of materials such as wood, glass, metal, paper and rubber with several of these applications being developed by Baekeland during the early stages of his resin commercialization. Many recent technical conferences have been held and were identified with important early Baekeland advances such as Baekeland 2007, Baekeland 2009 and the more recent Baekeland 2011 – all commemorating different initial activities of Baekeland and centennial recognition of his 1907 patent, first production of phenolic resin in Erkner, Germany in 1909 and the centennial celebration of the production of phenolic resin in Japan in 1911. This presentation provides an overview and evaluation of large volume application markets for resole and novolak resins in 2011 and comments related to anticipated greater growth of novolak resins over resole resins. Both resole and novolak resins are viewed as reactive intermediates that undergo a variety of chemical transformations into various improved and in many instances upgraded resin systems that lead to both recognizable and newly reactive resins for value added products. New areas involving phenolic resins are described and consist of Phenol Resorcinol Formaldehyde (PRF) resins, Nanomodification, Novel Novolak Process, ionic liquids, Phenolic Hybrids, and Poly Aryl Ether Amide based on novolak and phenylene bisoxazoline (PBO).

• Median peaks of the return stroke current and the ICC fast pulses in this study are 6.4 kA and 3.0 kA, respectively. • Observed parameters do not show much difference from those observed at tall structures considering instrumental effect. • The local conditions do not have much inference on the parameters of the fast pulses as well as the return strokes. • The local conditions such as height of the different charge layer have some influence on the IS of the upward flashes. The authors have carried out measurement of the current waveforms associated with lightning discharges to wind turbines at Nikaho near the coast of the Sea of Japan since 2013. In this paper measured waveforms in winter up to 2020 are investigated and the current waveforms associated with return strokes after the extinction of the ICC (initial continuous current) and fast pulses superimposed on the ICC with the current peak of 2 kA or higher and with the risetimes of 8 µs or shorter are studied. The median current peaks of the 107 return strokes and the 123 fast pulses were 6.4 kA and 3.0 kA, respectively. The observed median current peaks of return strokes and fast pulses at the Nikaho wind turbines (6.4 kA and 3.0 kA) do not show much difference from those observed at the Gaisberg tower (9.2 kA and 4.2 kA), the Säntis tower (8 kA and 3.4 kA) and the Peissenberg tower in Germany (return stroke: 8.5 kA but no report on fast pulses) when the long sampling interval and the low upper cutoff frequency of the measuring system at the Nikaho wind turbines is taken into account.

Abstract: Renewable energy sources derived principally from solar energy have been gaining ground over the last few years and are now beginning to contribute to the global energy mix. Solar energy in the form of direct electricity conversion (photovoltaics) is already very popular in countries such as the United States, Germany and Japan. The enormous potential of photovoltaic (PV) technology is also obvious and favourable in countries with high irradiation such as the Mediterranean region. The objective of this paper is to review the different up and coming PV technologies, to explore the potential of different PV systems in countries with high solar irradiation and to compare their performance through the assessment of thirteen different types of PV systems that have been installed side by side in Nicosia, Cyprus and Stuttgart, Germany. Finally useful insight into the performance of the PV systems as a function of the meteorological conditions and location will be highlighted. [Copyright &y& Elsevier]

While Germany and Japan are going through major energy reforms, natural gas consumption is taking a growing share in their energy supply. This paper adopts a Machine Learning approach to assess the causal link between natural gas consumption and economic growth for both economies. A Causal Direction from Dependency (D2C) algorithm with the interconnection of the sub-class is employed using yearly data from 1970 to 2018. The interconnections of the sub-classes are found for both economies, indicating evidence of causalities operating in both directions. In addition, the propagation over the seven eras is linear and homogeneously continue for Japan, while this effect meets a stabilization phase in the fifth era for Germany. The empirical findings claim strong support for the existence of a bidirectional causality between these variables in Germany and Japan, which is in line with the "feedback hypothesis". Although the strength of this bidirectional relationship is clear for both economies, its time-propagation is expected to be longer for Japan. Accordingly, this study claims that the gas supply should be further strengthened to progressively replace the most polluting fuels (oil and coal) and ensure a feasible transition towards a renewable path. • The causal link between natural gas consumption and economic growth exists for both countries. • Predictive analysis highlights a propagation effect between natural gas consumption and economic growth for both economies. • We found empirical sustain for the "feedback hypothesis" for Germany and Japan.

Abstract: The different approaches that other countries take to land use reflect many national variables, including planning systems, institutional structures, socio-cultural characteristics, population pressures and environmental priorities. Literature reviews of relevant land-use issues in Germany, Japan, the Netherlands, New Zealand and Sweden provided the background material for this paper. Other European countries appear to offer models of more pro-active and indicative land-use planning, in contrast to the adversarial system in the UK, and a much stronger regional focus. This seems to have made it easier to implement other policies, for example on renewable energy. Experience with liberalisation of agricultural markets, and the promotion of environmentally sustainable farming are both relevant to an increasingly polarised agricultural sector in the UK. Cutting across all these themes is a reflection on governance of land use. Of the countries considered, Sweden''s focus on environmental sustainability, international responsibility and long-term consistency of direction appears to be most closely aligned to the coming land-use challenges. When drawing conclusions from this review it is important to bear in mind the effect of differences in bio-geographic factors, socio-economic conditions and political culture, both in other countries and within the UK.
