双向吸收—抑制改良试验检测人指甲内,ABH血型物质

本文应用96孔Ⅴ型微量酶标板，采用双向吸收-抑制试验对人指甲内ABH血型物质的测定进行了初步探索，对8例A型、8例B型、6例AB型和5例O型人的指甲进行了检测，其结果与已知血型完全相符。实验表明，用96孔Ⅴ型微量酶标板进行双向吸收一抑制试验，检测人指甲内ABH血型物质是可行的。     

Partisanship and public reason

In the large body of literature concerning John Rawls’s Political Liberalism (1993) and his conception of public reason, little attention has been paid to the implications that the constraints of public reason have for partisans, i.e. citizens who participate in politics through political parties. This paper argues that even on the basis of a ‘mild’ understanding of Rawls’s conception of the constraints of public reason, which takes into account the various stipulations Rawls provided throughout his later work, when applied to partisans the constraints of public reason lose none or little of their hindering force. This seriously undermines the contribution that parties and partisans can provide to the change and the varieties of public reason that Rawls himself advocates as a response to social change and, therefore, to political justification and legitimacy. Parties articulate, coordinate and enhance societal demands which, without their support, may remain unheard and fail to change the acceptable terms of public reason and political justification. If the political speech of partisans is restrained, this potential for change (and, therefore, its contribution to political legitimacy) is seriously undermined.     

Institutional Models for Track Two Interventions

Conflict resolution as an academic field was built by pioneers like John Burton on the idea that conflict resolution academics must accomplish three basic interlocking tasks: conduct cutting‐edge research, educate students, and make a positive contribution to the real‐world work of practitioners engaged in resolving actual conflicts. Over time and as the field has grown, so have the demands to produce research deemed rigorous enough according to increasingly competitive and rigid traditional standards and so too have the demands of teaching growing numbers of students. Research and teaching commitments thus diminish the time and support available to engage in practice. In this article, I consider those pressures within universities and also consider the options available to conflict resolution scholar–practitioners outside the traditional university     

兔F型多杀性巴氏杆菌的分离鉴定及其致病性

对从山东某獭兔养殖场病死仔兔肺中分离的1株疑为巴氏杆菌菌株进行了菌落形态学观察及培养特性、革兰氏染色、生化反应、仔兔致病性回归试验、小鼠毒力试验,并采用PCR方法对该分离株进行了种属及荚膜血清型鉴定。结果显示,该分离菌株革兰氏染色阴性,生化试验及PCR鉴定结果显示为F型多杀性巴氏杆菌,能引起獭兔仔兔肺出血、坏死,并致部分仔兔死亡。表明该分离菌株为比较少见的兔F型多杀性巴氏杆菌。     

Cross-border Mergers and Acquisitions in different legal environments

The aim of this paper is to analyze the influence of the legal and institutional environment on bidder firm returns around the announcement date of cross-border Mergers and Acquisitions (M&As). The database includes 469 M&As of European (221 cross-border and 248 domestic) listed firms, with target firms being worldwide public or private firms (40 countries), over the 2002–2006 period.Shareholders of acquiring firms place greater value on cross-border M&A announcements than on domestic ones. The stronger (weaker) the legal and institutional environment of the acquirer firm country in comparison with that of the target firm country, the more positive (negative) the effect on acquiring-firm shareholders’ valuation of M&As.     

Technology and torts: Memory costs, nondurable precautions and interference effects

This article examines the influence of nondurable precaution technologies on the expansion of tort awards. We provide four contributions to the literature. First, we present a general, formal model on durable and non-durable precaution technology that focuses on memory costs. Second, because liability exposure creates interference, we argue that tort law perpetuates the expansion of awards. Third, because plaintiffs do not consider the social costs of interference effects, private litigation induces socially excessive suits. Fourth, while new harm-reducing technologies likely increase accident rates, such technologies also raise the ratio of trial costs to harm, leaving undetermined the overall effect of new technologies on the rate of litigation.     

Perfect Failure: the USA,Cuba and the Bay of Pigs, 1961

In 1961 the US Central Intelligence Agency master‐minded a sea‐borne invasion by Cuban exiles aimed at overthrowing the regime headed by Fidel Castro. With minimal logistical support from the USA the attempted counter‐coup launched at the Bay of Pigs was an unqualified disaster: a ‘perfect failure’, in the words of an authoritative contemporary. This essay locates the fiasco in the longer history of US–Cuban relations, concentrating on the Cold War years, the history of US political intervention and subversion in Latin America, and the dictatorship of Fulgencio Batista and the rise of Castro himself—both men offering different models of Latin American caudillismo (the power and cult of military strongmen). The essay concludes with an analysis of Cuba as an issue in US domestic politics and the impact of the Bay of Pigs in consolidating the Cuban revolution and setting the framework for the Cuban Missile Crisis of October 1962.     

STRtyper-10F/G联合CODIS系统鉴定突变三联体和二联体

目的 评估STRtyper-10F/G、CODIS系统联合应用在突变三联体和二联体亲子鉴定中的鉴定能力.方法 104例亲子鉴定样本,采用CODIS检测,其中3例三联体发现突变的案例以及101例二联体中73例认定和28例排除案例,分别再使用STRtyper-10F/G检测;统计认定和排除情况、比较单独使用和联合使用在排除关系案例中的表现和法医学参数(H、DP、PE、PIC、TPI).结果 3例存在突变基因的三联体案例加做STRtyper-10F/G未发现更多的矛盾基因座,PI值均大于10 000,可作出认定结论;73例二联体认定案例中13例PI不足10 000,加做STRtyper-10F/G系统后PI＞10 000,可确认认定;28例排除案例最高排除率CODIS为50.00％、STRtyper-10F/G为64.29％;两个体系均具有较高的杂合度(H≥0.7)和信息量(PIC ＞0.7),联合应用CEP为0.999 999 999 505 3.结论 STRtyper-10F/G和CODIS系统联合应用可满足突变三联体和二联体亲子鉴定的需要.
