The U.S. Radium Industry: Industrial In-house Research and the Commercialization of Science

A fierce debate ensued after the announcement in 1913 in the U.S.A. that all rights and ownership of radium-bearing ores found on public land would be reserved by the government. At stake was the State monopolization of radium that pitted powerful industrialists with radium claims, mainly in the Colorado area, against the Bureau of Mines and prestigious physicians who wished to reserve radium for medical uses. This article describes the strategies of one of the biggest U.S. radium industries that dominated the radium market, created huge customer bases, and legitimized their role within the scientific community. In contrast to the European “radium situation,” radium extraction, production, and marketing in the United States was controlled by the industry; and industrial in-house research was clearly separate from that done in academic circles. The production of knowledge was ready-made in the factory and was entangled with commercial orders and advertising patterns.

Intellectual property rights and U.S. information goods exports: the role of imitation threat

Trade in information goods is particularly sensitive to the strength of intellectual property rights (IPR) and encounters an apparently different pattern of imitation threat compared with manufacturing trade, but the information goods trade–IPR nexus is less systematically investigated. This article analyzes whether and how U.S. information goods exports are sensitive to national differences in IPR protection and the degree of threat-of-imitation from the dynamic perspective. Employing the technique of instrumental variables for a dynamic panel model to consider the hysteretic effect and controlling the endogeneity problem, the empirical results show that the strength of the importing country’s IPR protection overall exhibits a trade-enhancing effect, supporting the standpoint that stronger IPR protection will induce more trade. Moreover, we adopt the piracy rate as a proxy for threat-of-imitation to examine its role on the information goods trade–IPR nexus. Empirical findings validate the prevalence of the market expansion effect wherever the degree of imitation threat of importing countries is high or low, because the technology level and production cost of reproduction are very low. It implies that the existing theory on threat-of-imitation may not apply to the information goods trade.

The Economics of Monomedia and Cross-Media Expansion: A Study of the Case Favouring Deregulation of TV and Newspaper Ownership in the U.K.

Since the early 1990s, regulators across the globehave faced increasing pressure from media firms toliberalise domestic media and cross-media ownershiprestrictions. Based on empirical research carried outin the U.K., this paper examines the ``economic' case putforward in favour of deregulation. Findings suggestthat, although factors other than size will affectperformance, there is generally a strong and positivecorrelation between the market share and the operatingprofitability of firms involved in either televisionor radio broadcasting or newspaperpublishing. But, with regard to cross-media ownershipof television and newspapers, there is nocompelling evidence that diagonal integration bringsabout inherent synergies, economies of scope or othereconomic benefits. Thus, whereas a variety ofeconomic efficiency gains may be available to justifya relaxation of restrictions over monomedia expansion,few such benefits can be found in support ofderegulating cross-ownership of television andnewspapers.     

The Dynamics of Chart Success in the U.K. Pre-Recorded Popular Music Industry

In this paper we investigate the dynamics of chartsuccess in the U.K. pre-recorded popular music industryover the period 1980 to 1993 using the British albumchart listings. We find that the incidence of chartsuccess is substantially skewed to the right, whethermeasured by total weeks spent per artist, averageweeks spent per album, or the total number of albumslisted per artist. We subsequently investigatepossible determinants of the length of chart survivalof albums in order to determine what may be drivingthe observed skewness. Our results indicate that thetype of album, seasonal demand, and initial popularityplay an important role in ensuring continued chartlisting of an album.     

敦煌写卷S.526考

本文首先从s.526卷尾所署的闰月切入,然后结合敦煌写卷、敦煌石窟等原始材料,认为卷中的阴氏夫人是张承奉的母亲,阿郎是张承奉,该写卷产生于张承奉时期,这个时期有一位阴姓的国舅.该写卷所反映的州主阿郎和和尚尊师之间的紧张关系,以及纪年未用中原年号等变化,正符合张承奉时期由于金山国的建立随之而带来的宗教政策以及与中原政权关系上的变化.最后断代在912年.
