Since the energy crisis in 1960s, crucial research and activities were spurred to improve efficiency decrease environmental pollution. To deal with various problems construction industry are facing, concept of green buildings (GBs) has been gradually shaped put forward all over world, building rating systems (GBRSs) have developed. The GBs covers a wide range elements, its definition is constantly updated as develops. This paper compares development backgrounds statuses countries. It also...

Global greenhouse gas (GHG) emissions from the construction industry continue to increase at an annual rate of 1.5%. It is particularly important understand characteristics building life cycle reduce its environmental impact. This paper aims assess impact prefabricated buildings and traditional cast-in-situ over using a hybrid model. A case study with 40% assembly in Japan was employed for evaluation. concluded that total energy consumption, carbon 7.54%, 7.17%, respectively, less than...

ABSTRACT Using a sample of firms from 51 countries and difference-in-differences approach that exploits corporate governance shocks induced by cross-listing in the U.S., we find tend to engage less tax avoidance after cross-listing. This effect is more pronounced for experience significant improvements governance, with weaker shareholder protection disclosure requirements. Taken together, results indicate U.S. helps align interests managers shareholders reduces managerial diversion. Data...

We posit that geopolitical events elevate investor risk prompt equity investors to shift capital from emerging markets safer mature markets, raising the cost of for firms in economies. Using a sample 55,900 observations spanning 19 economies 1987 2018, we find higher increases capital, on average. further this effect is moderated by country-level institutional context (constraints executive branch government and regulatory arrangements) firm-level factors (cross-listing U.S. foreign sales).

Abstract In this article, we examine the effects of economic policy uncertainty (EPU) on insider trading. Two hypotheses predict that EPU is positively related to trading volume and profitability: (1) private benefits hypothesis, which states insiders exploit their information advantage realize abnormal profits, (2) signaling trade signal stock market participants. We find significantly profitability purchases, purchase more frequently during high‐EPU periods. Additional analysis provides...

Dynamic state estimation (DSE) plays an important role in the real-time control and monitoring of distribution systems, which are high-dimensional space–time systems. The degree nonlinearity system increases drastically with availability sustainable energy diversification load types, thereby reducing accuracy standard linear model. Under existing schemes, measurement noise may not follow a Gaussian distribution. Therefore, Koopman operator-based Kalman particle filter (KKPF) is proposed...

With China's urbanization process accelerated ceaselessly, construction developing rapidly, the great architectural waste discharge. At present, production but also has far exceeded rate of domestic can bear. Meanwhile, disposing mode, such as mechanical landfill and burned, resulting in huge resources environmental pollution. So how to efficiently processing using reasonable wastes have become our country now faces a severe ecological problem. This paper discusses causes, handling...

Using a sample 55,900 observations spanning 19 economies 1987 2018, we find higher increases capital, on average. further this effect is moderated by country-level institutional context and firm-level factors.

We examine the impact of sovereign wealth fund (SWF) investments on corporate socialresponsibility (CSR) practices investee firms in U.S. Employing a difference-in-differencesmethodology, we find significant increase CSR following by SWFs. Our resultshold for all components and are robust across various tests endogeneity alternativemodel specifications. Furthermore, effect is more pronounced SWFs with lowerlevels transparency accountability, higher levels political motivations. Overall,...

Abstract Sheep wool, an important natural raw material for textile industry. This article propose a watersaving sheep wool cleaning processing. For each kilogram of containing about 35% impurities, the water loss in washing is as low 2.5 liters. Wool sewage with high content COD (chemical oxygen demand), up to 20-30 g/L, treated by neutral detergent and then solid hydroxide (Calcium Hydroxide or Alum) cationic polyacrylamide (CPAM) order have fast flocculation waste. The wastewater can be...

We empirically investigate the effect of economic policy uncertainty (EPU) on corporate cash holdings using a large sample international firms. EPU intensifies concerns investors managerial self-dealing and political extraction. Consequently, potential cost (i.e., expropriation) outweighs its benefit precautious motive), optimal amount decreases. find supportive evidence that firms hold less when is high. further show market discounts excess under high uncertainty, but this negative...

This article examines the effects of economic policy uncertainty (EPU) on insider trading. Two hypotheses predict that EPU is positively related to trading volume and profitability: 1) private benefits hypothesis, insiders exploit their information advantage realize abnormal profits, 2) signaling trade signal stock market participants. We find significantly profitability purchases. also purchase more frequently during high-EPU periods. In additional analysis, we strong support for but no hypothesis.

With an emphasis on deliberative processes that occur between managers and stakeholders, the political corporate social responsibility (PCSR) literature has made important advances to our understanding of CSR activities. However, these contributions have tended focus exclusively organizational settings. We contend firm-level is incomplete without considering interrelations organizations wider socio-political environment. Building work in comparative politics about formal informal...
