Power distribution in the maritime commons is changing. The inevitable relative decline of U.S. sea power provides an opening not only for China as a rising challenger but also for the European Union as a cooperative security provider. Although such a claim may have seemed farfetched a few years ago, the performance of the European Union in the counter-piracy Operation Atalanta off the coast of Somalia and in the Gulf of Aden, illustrates the possibility that the European Union will prove to be an unexpected player in the maritime commons in the twenty-first century. This possibility suggests a renewed transatlantic dialog over the governance of the maritime commons.  相似文献

The post-9/11 threats to American security require a complete revision of American national strategy. For too long, presidents have had to favor quick, cheap solutions to crises, unable to count on support from the “homebody” public for long, drawn-out conflicts. “Cheap hawks” among them have hoped that apocalyptic rhetoric will suffice when resources fall short; “cheap doves” hope that by ignoring the threat, it will go away. But with the war on terror, the revival of geopolitics, and ever-accelerating globalization, the U.S. tradition of bellicose rhetoric backed by underwhelming force is a recipe for failure. To effectively manage its threats, America needs a new catechism and to make sure its economic, energy, and military policies support this.  相似文献

After months of bombing, NATO achieved only a stalemate in Libya. That disappointing result may reflect NATO's commitment to respect “international humanitarian law,” now understood to impose severe limits on military operations that might harm civilians. This body of rules is a departure from traditional understandings of the law of war. The embrace of these inhibiting rules raises serious questions about whether western nations are now prepared to fight and win actual wars.  相似文献

Purpose

Tests of social support theory have relied on aggregate crime rates as the outcome of interest, but such a focus ignores the potentially important macro-level processes and effects on individual-level behavior We thus perform the first multi-level investigation of social support theory.

Methods

Multilevel modeling is used to explore whether the two varieties of county-level social support - the presence of charitable organizations and AFDC expenditures - are associated with recidivism in a sample of Florida prison releasees.

Results

Results show that while social support explains little variation in individual-level recidivism, a combination of private and public social support may reduce the likelihood of reconviction for drug offenses.

Conclusion

Findings provide mixed evidence for the prospect that social support—whether governmental or nongovernmental—is associated with recidivism among recently-released inmates.  相似文献

With continual advances in Internet capability the child pornography market is experiencing a boom in demand and supply. Attempts to reduce the market challenge legislators, law enforcement agencies, practitioners and researchers alike – due in large part to the decentralised and global nature of the Internet. Much research has focused on frequent users of child pornography and whether such behaviour is interrelated with child sexual assaults. This article instead draws attention to onset, the first deliberate viewing of child pornography. It presents the results of a three-month study of a global Peer-to-Peer network, isoHunt. Analysis of the site’s Top 300 search terms indicated that child pornography is consistently shared. Risk factors for onset are discussed, including the potential normalisation of child pornography among Internet subcultures. Strategies are discussed to encourage subcultures to inhibit child pornography use and to increase understanding of the harms associated with such material. Implications for legal systems, policy and research are explored.  相似文献

“The task of a leader is to get his people from where they are to where they have not been” Henry A. KissingerWith stuttering growth in the Western economies where major sourcing and TMT (Technology, Media & Telecoms) contracts are pervasive, it is perhaps not surprising that internal and external legal counsel are increasingly being called upon to advise clients on termination options and strategies to effect or oppose a threatened termination for breach of contract. This short paper considers why this has happened and the other factors which are in play which have meant that advice on termination and the renegotiation of contracts in this context has become more common. Expertise in this area is part of an IT lawyer’s tool kit and we consider that this is an area where internal and external legal counsel can make a substantial difference in delivering solutions to their clients.In this paper I talk about termination and renegotiation interchangeably. The reason for this as will become clear is that all forms of termination, whether they are consensual or contested, will involve some form of renegotiation of the terms of the contract between the parties. This is because it is almost impossible except perhaps in the simplest of installations to predict the nature in which a supplier or a customer may wish to change the services provided, and consequently even the most carefully crafted of exit and transition clauses, schedules and plans will require some form of post-contract negotiation between the customer, the outgoing supplier and potentially a new supplier or suppliers. This will necessarily involve some form of renegotiation of the terms of the contract between the parties.This paper looks at renegotiation in the context of a termination scenario rather than dealing with renegotiation during the normal course of operation of the contract.  相似文献

The popular social networking site, Facebook, recently launched a facial recognition tool to help users tag photographs they uploaded to Facebook. This generated significant controversy, arising as much as anything, from the company’s failure to adequately inform users of this new service and to explain how the technology works.The incident illustrates the sensitivity of facial recognition technology and the potential conflict with data privacy laws. However, facial recognition has been around for some time and is used by businesses and public organisations for a variety of purposes – primarily in relation to law enforcement, border control, photo editing and social networking. There are also indications that the technology could be used by commercial entities for marketing purposes in the future.This article considers the technology, its practical applications and the manner in which European data protection laws regulate its use. In particular, how much control should we have over our own image? What uses of this technology are, and are not, acceptable? Ultimately, does European data protection law provide an adequate framework for this technology? Is it a framework which protects the privacy of individuals without unduly constraining the development of innovative and beneficial applications and business models?  相似文献
