Legal context: The income streams of originating pharmaceutical manufacturersare under pressure as never before, from increasing R&Dcosts, regulatory pressures, and competition from generic manufacturers.This article examines the various strategies which originatingpharmaceutical manufacturers have adopted in response to thesethreats. Key points: The authors consider various strategies, including SupplementaryProtection Certificates, life-cycle management (‘evergreening’),second pharmaceutical use claims, trade marks, and the use ofdata exclusivity and interim injunctions, in order to prolongthe protection given to existing products, and to manage competitionfrom generic manufacturers. Practical significance: The authors also include two real-life case studies in orderto illustrate the practical applications of the strategies discussedin the article.  相似文献

Martha Joynt Kumar is a professor of political science at Towson University. Her book, Managing the President’s Message: The White House Communications Operation (Johns Hopkins University Press, 2007), examines the media and communications operations of the administrations of Presidents Bill Clinton and George W. Bush. In March 2008, Professor Kumar was interviewed in the White House Press Briefing Room by Kevin R. Kosar on behalf of Public Administration Review. As this interview went to press, the American Political Science Association’s Presidency Research Group announced that it had awarded Managing the President’s Message the Richard E. Neustadt Award for best book on the U.S. presidency published in 2007.  相似文献

Political scientists lack domain‐specific measures for the purpose of measuring the sophistication of political communication. We systematically review the shortcomings of existing approaches, before developing a new and better method along with software tools to apply it. We use crowdsourcing to perform thousands of pairwise comparisons of text snippets and incorporate these results into a statistical model of sophistication. This includes previously excluded features such as parts of speech and a measure of word rarity derived from dynamic term frequencies in the Google Books data set. Our technique not only shows which features are appropriate to the political domain and how, but also provides a measure easily applied and rescaled to political texts in a way that facilitates probabilistic comparisons. We reanalyze the State of the Union corpus to demonstrate how conclusions differ when using our improved approach, including the ability to compare complexity as a function of covariates.  相似文献

While research suggests that public service motivation may be a dynamic trait in individuals, particularly early in their careers, other recent research has found that PSM may be relatively stable upon entry into the workforce (Vogel and Kroll 2016). To identify more precisely the decision point among individuals considering a public service career, the present study uses the antecedents of public service motivation framework (Perry 1997) to predict participation in AmeriCorps, a voluntary national service program in the United States. Findings reveal that antecedent conditions of PSM, including the prevalence of seeing family members and mentors help others as well as participation in student government, predict whether an individual will join an AmeriCorps programs. Many of these self-reported motivations support the argument that people attracted to public service hold strong other-regarding values. These findings suggest that human resources managers would be wise to consider these antecedent conditions to public service motivation when identifying pools of talent for recruiting and selecting prospective employees.  相似文献
