Intuitively, we associate different political parties with different types of policy. In contrast, this paper shows that in the absence of differential costs of membership among parties (that is, if party membership ischeap talk), party labels cannot perfectly signal the ideologies of candidates. However, under certain conditions parties can signal candidate types imperfectly. The paper therefore also provides an example of how costless communication can be effective in games of partial conflict. 相似文献

AbstractTwo approaches to identity have been employed to explore issues in Japan's international relations. One views identity as constituted by domestic norms and culture, and as constitutive of interests, which in turn cause behaviour. Proponents view Japan's ‘pacifist’ and ‘antimilitarist’ identity as inherently stable and likely to change only as a result of material factors. In the other approach, ‘Japan’ emerges and changes through processes of differentiation vis-à-vis ‘Others’. Neither ‘domestic’ nor ‘material’ factors can exist outside of such identity constructions. We argue that the second, relational, approach is more theoretically sound, but begs three questions. First, how can different identity constructions in relation to numerous Others be synthesised and understood comprehensively? Second, how can continuity and change be handled in the same relational framework? Third, what is the point of analysing identity in relational terms? This article addresses the first two questions by introducing an analytical framework consisting of three mutually interacting layers of identity construction. Based on the articles in this special issue, we argue that identity entrepreneurs and emotions are particularly likely to contribute to change within this model. We address the third question by stressing common ground with the first approach: identity enables and constrains behaviour. In the case of Japan, changes in identity construction highlighted by the articles in this special issue forebode a political agenda centred on strengthening Japan militarily. 相似文献

Banknote evidence is often submitted after a suspect has attempted to disguise or remove red dye stain that has been released because of an anti-theft device that activates after banknotes have been unlawfully removed from bank premises. Three chlorinated compounds have been synthesized as forensic chemical standards to indicate bank security dye bleaching as a suspect's intentional method for masking a robbery involving dye pack release on banknotes. A novel, facile synthetic method to provide three chlorinated derivatives of 1-(methylamino)anthraquinone (MAAQ) is presented. The synthetic route involved Ultra Clorox bleach as the chlorine source, iron chloride as the catalyst, and MAAQ as the starting material and resulted in a three-component product mixture. Two mono-chlorinated isomers (2-chloro-1-(methylamino)anthraquinone and 4-chloro-1-(methylamino)anthraquinone) and one di-chlorinated compound (2,4-dichloro-1-(methylamino)anthraquinone) of the MAAQ parent molecule were detected by gas chromatography mass spectrometry (GC-MS), and subsequently isolated by liquid chromatography (LC) with postcolumn fraction collection. Although GC-MS is sensitive enough to detect all of the chlorinated products, it is not definitive enough to identify the structural isomers. Liquid-state nuclear magnetic resonance (NMR) spectroscopy was utilized to elucidate structurally the ortho- and para-mono-chlorinated isomers once enough material was properly isolated. A reaction mechanism involving iron is proposed to explain the presence of chlorinated MAAQ species on stolen banknotes after attempted bleaching. 相似文献

Gladiator remains from a recently unearthed cemetery in ancient Ephesus (Turkey) offer a unique opportunity for proving common theories involving the weaponry and techniques of gladiator fighting based on the evidence supplied by cranial bones. This mass grave is the first of its kind to undergo a thorough osteological and forensic examination. A minimum number of individuals (MNI) analyses revealed that at least 68 individuals. All individuals found turned out to have been males aged between 20 and 30 years, except for one female associated with a female slave gravestone, and one male aged 45-55 years, had been buried in this area of the cemetery. The male mean body height was 168 cm (S.D.=5 cm), which lies inside the normal range of height for Roman populations at those times. Eleven (16% of MNI) individuals exhibit a total of 16 well-healed antemortal cranial traumata. Five of the 11 individuals showed multiple trauma. Ten (15% of MNI) individuals exhibited a total of 10 perimortal cranial traumata. This is a surprisingly high frequency of deadly head injuries, taking into account that most of the gladiator types wore helmets. A possible explanation could be the frequently reported deathblow technique used by the hammer-carrying death god "Dis Pater". The gladiator weaponry is well known through historical sources. At least one injury per known type of offensive weapon could be identified, as well as evidence for the most popular, the gladiator trident, which was found to be represented by one perimortem and two antemortem injuries. Overall the reportedly very strict nature of combat rules for gladiator fights could be confirmed by the absence of multiple perimortal traumatized individuals, showing a lack of the excessive violence commonly observed on medieval battle ground victims. This graveyard gives the opportunity to confirm historical aspects and to check the reliability of forensic methods for identification of antemortem, perimortem, or postmortem bone lesions. Typical examples for these kinds of lesions and injuries are presented. The colour of the margins of the traumata proved to be the most distinguishing feature for postmortal lesions. 相似文献

If the defendant in a lawsuit is better informed than the plaintiff about the value of damages that could potentially be assigned by the court, biasing the burden of proof toward the plaintiff may lower aggregate efficiency losses from litigation. 相似文献

Using stochastic methods we illustrate that the Provisional Irish Republican Army's (PIRA) network is clustered along three primary dimensions: (a) brigade affiliation, (b) whether the member participated in violent activities, and (c) task/role within PIRA. While most brigades tended to foster connections within the brigade (that is, “closure”), the tendency to do so varied across the organization. Members who engaged with violent activities were far more likely to connect with each other; in later periods there is polarization into those who engage in violent activities and those who do not. Across brigades, those who engage in a particular task and role (improvised explosive device [IED] constructor, IED planter, gunman, robber/kidnapper/drug smuggler/hijacker) are more likely to connect with others who do the same task or play the same role than with other members who fulfill other roles. Standard forms of homophily (that is, the tendency to make connections with people who are similar in terms of demography or status) play a very weak role in explaining which members interact with one another. Finally, our analysis illustrates clear patterns of relational change that correspond to changes in the formal structures that PIRA's leadership promoted. 相似文献
