We model faction formation in a world where party politicians' objective is the development of an informed program of governance. Politicians' preferences reflect their own views and their information that, when aggregated via intraparty deliberations, influences the party manifesto. By joining a faction, a politician increases the influence of its leader on the manifesto, but foregoes his individual bargaining power. For broad model specifications, we find that a faction formation process allows power to be transferred to moderate politicians. This facilitates information sharing, increasing the capacity of the party to attain its objective. These positive welfare effects may hold even when factionalism restricts intraparty dialogue, and hold a fortiori when information is freely exchanged across factions. We conclude that the existence of ideological factions may benefit a party: It provides a means to tie uninformed or extremist politicians to more moderate and informed faction leaders. 相似文献

Management of a crime is the process of ensuring accurate and effective collection and preservation of physical evidence. Forensic botany can provide significant supporting evidences during criminal investigations. The aim of this study is to demonstrate the importance of forensic botany in the crime scene. We reported a case of a woman affected by dementia who had disappeared from nursing care and was found dead near the banks of a river that flowed under a railroad. Two possible ways of access to crime scene were identified and denominated “Path A” and “Path B.” Both types of soil and plants were identified. Botanical survey was performed. Some samples of Xanthium Orientalis subsp. Italicum were identified. The fall of woman resulted in external injuries and vertebral fracture at autopsy. The botanical evidence is important when crime scene and autopsy findings are not sufficient to define the dynamics and the modality of death. 相似文献

Various reformulations of the Coase theorem have developed normative corollaries on the choice of optimal remedies in the
presence of positive transaction costs. In this article, we consider the extent to which these propositions are affected by
the presence of asymmetric transaction costs, and we offer a reformulation of the Coase theorem which takes into account asymmetrical
transaction costs. Our analysis combines several insights from the existing literature on property-type vesus liability-type
remedies, identifying the conditions for the superiority of each type of remedy. Further, we consider the possible use of
mixed remedies and identify the optimal scope of such solution. 相似文献
