Tacit collusion between National Power and PowerGen, the dominant generators in England and Wales for most of the 1990s, was widely speculated but was not definitively proven. In the event of a legal determination, the best available evidence is a test of suspicious patterns of bidding behavior. The methodology has two stages: the first is to show that the suspects behave differently from the rest, which are assumed competitive; the second stage is to ask whether or not strategies of suspects affect one another. Results: the impact of suspects on the aggregate bid function can not be explained away by costs and common market events, and a seemingly unrelated regression (SUR) on strategies of the suspects reveals bid inter-dependence and co-ordination on demand trends. A quarter of the dynamic indicators support an inference of tacit collusion. The existence of multiple equilibria in supergames, however, prevents a conclusive statement.  相似文献

Among currently available technologies, transcranial direct current stimulation (tDCS) is one of the most promising neuroenhancements because it is relatively effective, safe, and affordable. Recently, lay people have begun to build—or purchase—the tDCS device to use it at home for treatment or as a cognitive enhancer. The tDCS device is currently not covered by the existing regulatory framework, but there are still significant potential risks of misusing this device, and its long-term effects on the brain have not been fully explored. Thus, researchers have argued the need for regulations or official guidelines for the personal use of tDCS. However, until now, no systematic research on the do-it-yourself (DIY) tDCS user community has been done. The present study explores the basic demographic characteristics of DIY tDCS users as well as why and how they are using this device through a questionnaire survey, in-depth interviews, and a content analysis of web postings on the use of tDCS. This preliminary but valuable picture of the DIY tDCS user community will shed light on future studies and policy analysis to craft sound regulations and official guidelines for the use of tDCS.  相似文献

This Article addresses the issue of whether a court may appoint a Parenting Coordinator (PC) with decision‐making authority in the absence of a statute or court rule. The Article identifies possible sources of authority for the appointment of a PC with decision‐making authority in a state with no authorizing statute or court rule. It also provides a paradigm for constructing an appointment that allows for the benefits of Parenting Coordination but does not delegate decision‐making authority to an extent that it would constitute an impermissible delegation of judicial authority.
    Key Points for the Family Court Community:
  • Where a court seeks to appoint a PC with decision‐making authority in the absence of an authorizing statute or court rule, the court may find some authority allowing the appointment in (1) its equitable authority over child custody and visitation, (2) its authority to enforce its own orders, or (3) its authority to appoint other extrajudicial assistants such as a special master or mediator.
  • Where a court seeks to appoint a PC with decision‐making authority in the absence of an authorizing statute or court rule, the court must craft an appointment that delegates enough decision‐making authority to the PC for parenting coordination to be effective yet, at the same time, not so much decision‐making authority as to render the appointment an impermissible delegation of a judicial function, specifically:
    • The PC's role should be limited to assisting the parties in implementing custody and visitation terms already decreed by the trial court.
    • A PC should be appointed only if the parties to the divorce consent to the appointment or if the trial court makes a finding that the case is a high‐conflict case.
    • The parties must have the opportunity for the trial court to meaningfully review any decision of the PC so that the trial court retains ultimate decision‐making authority.

This paper explores the roles played by law in crisis management of financial markets and some possible consequences. Three questions are raised ‐‐about the ‘elastic’ use of law, about ‘sidestepping’ existing legal order by invention of new structures and about redistributive consequences. These questions are appraised empirically in relation to three areas of financial market law: public support given to banking from 2008 onwards; English case law concerning derivatives contracts when confronted with Lehman‐style insolvencies; and the European Stability Mechanism, which during summer 2015 was being primed in relation to Greece. On the first two case studies, law, having been mightily stretched, did not break. Likewise, legal sidestepping, as epitomised by the European Stability Mechanism, may result in a less coherent legal structure; however such incoherence may be not be fatal to the ensemble. On all three fronts, redistributive questions remain controversial, but controversy in itself does not undermine legal structures. A particular form of theory, the Legal Theory of Finance, is discussed in light of the case studies. Such theory may have an unfulfilled longing to discern law‐like regularities (ironically chasing economics).  相似文献

This study examines whether Criminology's Routine Activities Theory (RAT) and related Lifestyle Theory (LST) can account for variation between the attributes of victims of fatal ideologically motivated attacks (akin to terrorism) and the victims of non-ideologically motivated homicide incidents committed by far-Right extremists in the United States. This article makes four contributions. First, we empirically test Criminology theory in the context of terrorism by using routine activities to devise four core hypotheses to explain differences between the two types of victims. Second, our investigation uniquely includes a non-terrorist comparison group (i.e., victims of homicides committed by extremists for personal reasons like greed). Third, our study focuses on ideological victimization. Terrorism researchers have usually ignored victims because of the difficulty in accessing the necessary data. Finally, we also make a methodological contribution by showing that criminology can build upon the terrorism literature by utilizing open-sources. Using data from the Extremist Crime Database (ECDB), the results of a multivariate analysis partially supported the hypotheses, showing that RAT and LST offer empirically supported theoretical constructs that have the ability to differentiate between ideological and non-ideological homicides.  相似文献

The pastoralism of the Turkana has persisted in the challenging environment of northwestern Kenya for some 200 years. Yet many pastoralists find that they increasingly rely on food relief during droughts and famines. This article contextualises emergency responses to famine among Turkana pastoralists by considering their encounters with colonialism, development, and humanitarian interventions. It uses key informant interviews, participant observation, and content analysis, to analyse the benefits and challenges of a small-scale food relief programme. The article argues that such programmes can weaken the viability of pastoralism, and concludes with considerations for future policy and programming.  相似文献

This paper explores the political structures suitable for the realization of John Rawls’ The Law of Peoples (1999). In particular, it explores whether Rawls’ principles and fundamental foundations recommend establishing global institutions and, if so, whether, and in what sense, these institutions should be democratic. It is often suggested, either implicitly or explicitly, that The Law of Peoples would operate through the bilateral and multilateral interactions of, ideally conceived, nation-states. This paper argues, on the contrary, that it would advise a series of democratic global institutions. The case is developed with respect to the idea of a global institution with the remit of regulating international trade and applied, in the contemporary context, to the World Trade Organization (WTO).  相似文献
