The legal and technological battle in the music industry: Information-push versus information-pull technologies 总被引:2,自引:0,他引:2
Peer-to-peer (P2P) technologies are often seen as a threat by copyright owners because they encourage piracy by making digital copies easier to obtain. In response, major record companies have come up with new devices designed to protect original material, and lobbied to reinforce legal protection. We view traditional distribution as an information-push technology in which the firm pays to provide information to consumers and P2P as an information-pull technology where consumers spend resources to acquire information on products they have a potential interest in by searching, downloading and testing digital copies of original products before they make their purchase decision. We determine copyright owners’ protection strategies according to the level of legal protection, and we study their effects on profits and consumers’ surplus with the two different information transmission technologies. 相似文献

Trade volume between Central Asia and China has tripled since 2002. This study, which is based on Chinese sources, explains the reasons for this expansion in trade. Even if numerous obstacles remain, Government development policy in China’s western regions has induced trade growth between Xinjiang and Central Asia. Trade flows mainly consist of three blocks: economic activities of the Xinjiang Production and Construction Corps, commerce conducted by traders of the coastal province of Zhejiang, based in Xinjiang, and petty trade notably between Kazakhstan and Xinjiang. 相似文献

Politics must address multiple problems simultaneously. In an ideal world, political competition would force parties to adopt priorities that reflect the voters' true concerns. In reality, parties can run their campaigns in such a way as to manipulate voters' priorities. This phenomenon, known as priming, may allow parties to underinvest in solving the issues that they intend to mute. We develop a model of endogenous issue ownership in which two vote‐seeking parties (a) invest in policy quality to increase the value of their platform and (b) choose a communication strategy to prime voters. We identify novel feedback between communication and investment. In particular, we find that stronger priming effects can constrain parties to invest more resources in all issues. We also identify the conditions under which parties prefer to focus on their “historical issues” or to engage in “issue stealing.” 相似文献

This essay explores the imposition of the penal process in the Nouveau-Quebec Inuit area and makes explicit the diversity
in the modes of intervention and in the conceptions of state justice since the turn of the century. Four periods corresponding
to various goals and issues of penal intervention as well as four debates emerging around this intervention are identified.
The analysis shows that the intricacy of political, economic, and cultural identity is put into jeopardy when the implementation
of penal justice in an Inuit environment is attempted.

About 120,000 reference samples are analyzed each year in the Forensic Laboratory of Lyon. A total of 1640 positive control experiments used to validate and optimize the analytical method in the routine process were submitted to a multivariate exploratory data analysis approach with the aim of better understanding the underlying sources of variability. The peak heights of the 16 genetic markers targeted by the AmpF?STR® Identifiler® STR kit were used as variables of interest. Six different 3130xl genetic analyzers located in the same controlled environment were involved. Two major sources of variability were found: (i) the DNA load of the sample modulates all peak heights in a similar way so that the 16 markers are highly correlated, (ii) the genetic analyzer used with a locus‐specific response for peak height and a better sensitivity for the most recently acquired. Three markers (FGA, D3S1358, and D13S317) were found to be of special interest to predict the success rate observed in the routine process. 相似文献

Cycads in South Africa are facing an extinction crisis due to the illegal extraction of plants from the wild. Proving wild origin of suspect ex situ cycads to the satisfaction of a court of law is difficult, limiting law enforcement efforts. We investigated the feasibility of using multiple stable isotopes to identify specimens removed from the wild. Relocated and wild specimens from two species in the African genus Encephalartos (E. lebomboensis and E. arenarius) were sampled. 14C analysis indicated that a ± 30‐year chronology could be reliably obtained from the cycads. For E. arenarius, pre‐relocation tissue was consistent with a wild origin, whereas tissue grown post‐relocation was isotopically distinct from the wild for 87Sr/86Sr and δ15N. For E. lebomboensis, δ34S, δ18O, and 87Sr/86Sr were different between relocated and control plants, consistent with the >30 years since relocation. Our findings demonstrate the potential for a forensic isotope approach to identify illegal ex situ cycads. 相似文献
