The recent emphasis placed by several mainstream nationalist parties in Europe on sovereignty objectives invites analysis of the drivers behind this phenomenon. Their evolution is characterized by a complex set of dynamics that influences their options when faced with strategic decisions over participation in an existing state and/or challenging it by pressing for statehood. Spain constitutes a major laboratory for studying such dynamics owing to a diverse range of nationally- oriented parties. The experiences of the Basque Country and Catalonia show the continued relevance of center-periphery cleavages, especially when aggravated by European and global pressures and constraints, but party positioning between accommodation and sovereignty politics is influenced too by changing relationships between Basque and Catalan nationalist elites and civil societies and between mainstream nationalist parties and their direct competitors within party systems.  相似文献

The United Kingdom continues to undergo a rapid process of constitutional change, with an ongoing redistribution of law‐making and governmental powers to different parts of the Union under an expanded rubric of ‘devolution'. This article illuminates a pervasive sense of territorial constitutional crisis and opportunity in the most recent period, familiarly associated with, but not confined to, Scotland. Constructive and flexible federal‐type responses inside a famously uncodified constitution are championed. Wales, commonly treated as a junior partner in the United Kingdom, presents special challenges for constitutional and legal analysis and distinctive perspectives on the Union which have not received the attention they deserve. In tackling this deficiency, the article elaborates a ‘new Union’ concept of a looser and less hierarchical set of constitutional arrangements in which several systems of parliamentary government are grounded in popular sovereignty and cooperate for mutual benefit.  相似文献

This paper argues that reform of the wrongful trading remedy in section 214 of the Insolvency Act 1986 is unlikely to yield significant increases in civil recovery for creditors of insolvent companies. The paper argues that the widely held view that procedural restrictions in the provision have unduly limited the application of the remedy are without foundation and, likewise, that there is little evidence that current modest levels of litigation under the provision demonstrate underperformance in the sanction relative to the scale of the misconduct against which it is directed. The paper draws on a wide range of analytical and empirical evidence to argue that the scope for application of the sanction is inherently limited by factors independent of the particular rules within the statutory remedy.  相似文献

Four fluorescent fingerprint powders (RedWop?, GreenWop?, Basic Yellow?, and Yellow Powder?) were evaluated as a marker for blow fly larvae. Administration methods included ingestion (high vs. low concentration) or topical. Ingestion of high concentrations of Basic Yellow? and RedWop? caused higher larval mortality. Basic Yellow? delayed development and adult emergence while RedWop? and Yellow Powder? had a significant effect on particular stages of development, however, emergence time was not altered. Optimal administration is through ingestion at low concentration levels (<10%) or topically, with GreenWop? demonstrating minimal adverse effects. Optimum wavelength for discrimination between powders was 450 nm. This research can aid in investigative training to increase visibility of larval and pupal blow flies. It can also be used in entomological studies to differentiate between larval blow flies (or other dipteran) species or individuals to further understand complex interactions and behavior during larval development.  相似文献

Political marketing advances by engaging with new and advanced concepts from both of its parent disciplines. One of the most recent fields of brand research—the study of the human brand—is taken into the political marketing arena in this essay. Human branding is an emergent topic in mainstream marketing. The value as a brand of a person who is well-known and subject to explicit marketing communications efforts is being investigated in many fields. The concept has clear prima facie value in political marketing, where the role of a political leader as part of the political marketing offer has been recognized extensively. Politics is also a unique context given the relationship between leaders and parties, each of which has some unique brand associations. The process of exploring the application of human branding in politics also provides a context in which some of the interactions among party and leader, human brand, and organizational brand can be explored and further developed. Among the conclusions are that political party leaders require brand authenticity as an advocate of the party policy platform and brand authority to command the organization and deliver on the policies being advocated. Implications for party and campaign management are outlined.  相似文献

We distinguish between (i) voting systems in which voters can rank candidates and (ii) those in which they can grade candidates, using two or more grades. In approval voting, voters can assign two grades only—approve (1) or not approve (0)—to candidates. While two grades rule out a discrepancy between the average-grade winners, who receive the highest average grade, and the superior-grade winners, who receive more superior grades in pairwise comparisons (akin to Condorcet winners), more than two grades allow it. We call this discrepancy between the two kinds of winners the paradox of grading systems, which we illustrate with several examples and whose probability we estimate for sincere and strategic voters through a Monte Carlo simulation. We discuss the tradeoff between (i) allowing more than two grades, but risking the paradox, and (ii) precluding the paradox, but restricting voters to two grades.  相似文献
