国外废催化剂回收利用

1　日本日本由于缺乏各种金属资源 ,其生产催化剂的主要原料靠进口 ,因而早在 50年代日本就注意废催化剂的回收利用。早先主要回收贵金属 ,1955年以后开始回收废催化剂中的镍等有色金属。1970年日本就颁布了固体废物处理与清除法律 ,确认废催化剂为环境污染物。 70年代中期 ,日本建立了加氢脱硫回收装置。 1974年成立了废催化剂回收协会 ,会员约有 32家企业。其中丰田公司和日产汽车公司从事汽车排气净化催化剂的回收 ,三井金属矿业公司从事铂族金属的回收 ;八户冶炼公司的八户冶炼厂、矿业公司的敦贺工厂和三日市冶炼厂、大友化学工业公司…

On the Major Transformation of the Asia-Pacific Regional Structure北大核心CSSCISSCI

Recent years have witnessedsignificant changes in the Asia-Pacific regionalstructure featuring the shift in power balance among related countries as well as adjust-ments in their respective regional strategies. So what is the prevailing trend in thistransformation and what kind of regional order will likely emerge in the future？ To an-swer these questions, the paper tries to explore the following dimensions： the evolvingregional context, shift in power balance and power conversion, geo-political and geo-e-conomic developments and interactions between them, and evolving regional order. Asthe study shows, the broadening of regional geographical scope, the rise in the numberof actors involved, as well as changesin the relations among them, have combined tocast a pluralistic and complex flavor to the regional structure. While the power balanceamong China, the United States and Japan shifts, and power conversion is also occur-ring. China and Japan are paying increasing attention to their security roles, whereasthe United States under the Obama administration laid more stress on expanding itsgeo-economic clout. In spite of the intensifying geopolitical competition among China,the United States and Japan in recent years, a Sino-US strategic compromise-whichholds the key to regional geopolitics-isother front, some kind of geo-economicmore likely to take place in the future. On thecooperation will probably emerge. In the longerterm, it will be the geo-economic trend thatwill prevail over the geopolitical trend inthe region. Finally, the future evolution of regional order wiI1 mainly follow the eco-nomic logic, accompanied by the dilutionof its hegemonic and hierarchical nature.Hence, a pluralistic and complex regional community will emerge.     

Organization and incentives in the age of sail

The British Navy in the age of sail was the most successful bureaucracy of its time. Its organization and incentive structures differed importantly from contemporaneous private sailing ventures, but closely resembled those of today’s large corporations. To induce efficient effort, the navy used a hierarchical tournament, in which sailors competed for higher pay that came with promotions based on relative performance. Promotion probabilities, the option value of future promotions, and the higher effort required of men in higher ranks and on larger vessels, combined to yield a highly skewed pay structure.     

The German Hanse and Bergen – new perspectives on an old subject

Abstract

The Hanseatic League and her kontors (trading posts) were an integral part of the medieval trade system in Northern Europe. Hanse merchants dominated many markets in this region and managed to maintain a monopoly-like role in towns like Novgorod and Bergen for many centuries. Consequently, one focus of historical research about the Hanseatic League lay on the mechanisms that enabled the Hanse merchants to keep that strong of a position for such a long time.

This article is part of the discussion about this topic. Based on Lübeck merchants with business interest in the Norwegian town of Bergen, the so-called Bergenfahrers (Bergen travellers), it will give new insights into the Hansards' economical and social organization. The three main points are (a) the integration of the Bergen market in the Hanseatic trade network as an intermediary trading place on the vivid East–West route of Hanse trade; (b) the importance of the Bergenfahrers within the Hanse merchants' economical, social and political networks; and (c) the structure of the Bergenfahrers network patterns in the late Middle Ages.

In addition to new insights into the important role of Bergen and the Bergenfahrers within Lübeck's and the other Wendish Hanse towns' trading system, this articles provides further proof for the usefulness of the methods of Social Network Analysis in medieval economic research.     

Financial Reporting and Trade Credit: Evidence from Mandatory IFRS Adoption*

We investigate the effect of mandatory IFRS adoption on trade credit. We document that firms in countries that adopt IFRS receive more trade credit from their suppliers, consistent with improved financial reporting quality and comparability playing a role in facilitating informal financing. This increase is larger for countries with a low level of societal trust, a poor pre‐IFRS‐adoption information environment, and stronger legal enforcement. These cross‐sectional results suggest that the conditions under which higher‐quality information is made publicly available affect suppliers' decisions to provide trade credit. This increase is also larger for firms with greater exposure to foreign markets, a finding that highlights the importance of more comparable international financial reporting standards in facilitating cross‐country trade credit. We also find that IFRS adoption has a stronger positive effect on trade credit for firms with greater liquidity needs. Finally, we find that firms in countries that adopt IFRS also extend more trade credit to their customers. Overall, our results support the notion that financial reporting can have a causal effect on trade credit.

Integrated educational management for the universities

The research model investigates the integrated form of educational management for the universities. To enhance the operations, generate quality outcomes for the well-being of the society, this exploratory study depicts the two wings for the universities in four aspects including education development, education assessment, research development and research assessment. For the better understanding of education and research wings of the universities, the researchers identify different factors namely programs establishments, university culture, faculty capabilities and facilities those have been formularized by the structural equation modeling （SEM） through AMOS. The survey questionnaire was developed and analyzed the reliability and validity of the tools. The conceptual model for the universities provides a novel approach for decision makers to review and appraise their performance toward fulfillment of ultimate goals, i.e. producing high-caliber graduates and high-impact research outcomes for the betterment of the society. This research represents two contributions to the society including human resource contribution and research contribution.     

INFRASTRUCTURE POLICY IN INDONESIA, 1965–2015: A SURVEY

This survey, first, provides an overview of the main developments in the infrastructure sector in Indonesia during the past five decades and, second, considers what the main policy and management bottlenecks in infrastructure appear to be. The overview of main developments indicates that, in broad terms, most parts of the sector have expanded considerably but that the needs remain acute for further expansion and for attention to the maintenance of existing facilities. Demand for infrastructure is high, especially since the regulated prices set for infrastructure services are often low. Access is often difficult, however, because of shortages of infrastructure, and quality is often unsatisfactory because of poor maintenance and indifferent management. These problems of access are exacerbated by the regulation of prices. This overview also points to the markedly different performances of industries in which pro-competitive policies have been applied and those in which more traditional policies of close regulation have restricted the operation of markets.
