| Summary/Abstract |
Larger wind turbines are developed to harvest greater amounts of wind energy. This development increases the dilemma between ensuring aviation safety through obstruction lights and reducing citizen annoyance and possible stress effects caused by obstruction lights. In this study, a unique Danish sample is contrasted with a combined German-Swiss sample. Stronger stress effects due to the lights for the Danish sample compared to the German-Swiss study were found, an issue that could be related to the specific technical and site conditions. The prevalence of strongly annoyed residents was low. Significant factors for predicting obstruction light annoyance stress were identified, including: perceived fairness, consideration of the interests of the community, landscape change annoyance stress, number of visible wind turbines and age. It is recommended to enhance the planning process to reduce the stress among citizens, e.g. through improved communication, and to enhance the participation of residents in a way that allows for a meaningful consideration of people's concerns.

| Summary/Abstract |
The existing literature on the construction costs of nuclear power reactors has focused almost exclusively on trends in construction costs in only two countries, the United States and France, and during two decades, the 1970s and 1980s. These analyses, Koomey and Hultman (2007); Grubler (2010), and Escobar-Rangel and Lévêque (2015), study only 26% of reactors built globally between 1960 and 2010, providing an incomplete picture of the economic evolution of nuclear power construction. This study curates historical reactor-specific overnight construction cost (OCC) data that broaden the scope of study substantially, covering the full cost history for 349 reactors in the US, France, Canada, West Germany, Japan, India, and South Korea, encompassing 58% of all reactors built globally. We find that trends in costs have varied significantly in magnitude and in structure by era, country, and experience. In contrast to the rapid cost escalation that characterized nuclear construction in the United States, we find evidence of much milder cost escalation in many countries, including absolute cost declines in some countries and specific eras. Our new findings suggest that there is no inherent cost escalation trend associated with nuclear technology.

| Summary/Abstract |
Using an internationally linked patent database, this paper compares the types of R&D activities undertaken by multinationals in China by home country and industry. In China, multinationals recently began investing in R&D, mainly in the areas of product and manufacturing process development. However, US firms, which are the most actively invested in R&D, are involved in some technology-driven R&D activities; European firms are inclined toward market-driven R&D, while Japanese firms, which lag behind the other two, focus on production-driven R&D. This pattern may be related to the relative competitiveness of each country: Japanese firms are strong in electronics and automobiles, where production process improvement is important, while US firms flourish in science-based industries, such as pharmaceuticals and software, where interacting with the local science base is a critical factor.

| Summary/Abstract |
As an extension of traditional trade, digital trade is a new type of trade in the era of the digital economy. In this paper, we first analyze the digital trade‐related strategies of eight leading economies through word clouds and dissect China's digital trade‐related policies using the word frequency method by sorting through the digital trade‐related policy documents of 26 economies and Chinese provinces. We then evaluate the status quo of digital trade development in 111 countries and Chinese provinces by building a digital trade index system to determine the development environment and market potential. The results show that all countries attach great importance to digital technology, data and government guidance in the development of digital trade. The results also reveal that “development,” “service” and “construction” are the three most frequently used words in various Chinese documents. The overall level of China's digital trade is at the global vanguard, but is characterized by uneven regional development. In the era of digital trade, traditional international trade theory is also in urgent need of breakthroughs and innovation.
