The rapid growth of the populous Asian economies provokes profound economic changes and a shift in the balance of power. On the economic front, Asian leaders are confronted with the need to preserve the stability that has underpinned their prosperity, maintain an environment conducive to trade and investments and encourage domestic consumption while avoiding ecological disasters. Internationally, business competition will intensify with the strong presence of Asian manufacturers in global supply chains, growing price competition from Asian firms in domestic markets and global competition for energy, food, minerals and other commodities. Geopolitical concerns stem, in part, from Asia’s global quest for critical resources, conflicting territorial and maritime disputes and increasing military expenditures which affect security dynamics. China’s assertiveness over its periphery prompts an arm’s race in the region and concerns about Sino-American relations even though U.S.-Chinese relations may be less risky than China’s relations with its neighbours. The United States remains a key player in the Asia-Pacific region, with the capacity to alter balances and affect outcomes. Globally, the United States capacity to lead is now diminished and will continue to be so for the foreseeable future. Since no rising power is capable of exercising global leadership, a return to the "old normal" where no one power in geopolitical or economic terms dominates the world is to be expected.

Lorsque la guerre européenne éclate en août 1914, les États-Unis adoptent officiellement une position de stricte neutralité. Le pays n’en est pas moins tiraillé de l’intérieur pour autant. Au cours des quelque deux années et demi de neutralité, plusieurs moments forts et thématiques ont redéfini le rapport des États-Unis à la guerre européenne, jusqu’à justifier l’entrée en guerre en avril 1917, et propulsant par le fait même le pays à l’avant de la scène internationale. Cependant, les analyses relatives à la couverture de la guerre par la presse américaine pendant cette période sont pratiquement inexistantes. En se penchant sur les articles en une et les éditoriaux du quotidien The New York Times, il est possible de suivre l’évolution des thématiques liées au conflit et de comparer certains évènements que l’historiographie a ciblés comme étant à l’origine de l’entrée en guerre. Le but est de voir comment le NYT présente le conflit européen, de quelles façons le journal cherche à influencer son lectorat et, surtout, comment il « voit » peu à peu le conflit s’immiscer dans la vie des Américains. Certains thèmes comme le mouvement du preparedness et le traitement de la communauté germano-américaine nous renseignent sur les changements de perception qui s’opèrent dans la couverture du NYT. L’historiographie classique présente le torpillage du paquebot Lusitania le 7 mai 1915 comme le point à l’origine de la rupture officieuse de la neutralité américaine, au profit d’un sentiment proallié. Notre analyse tend à nuancer fortement cette affirmation. D’autres moments-clés et thématiques présentées dans le NYT ont eu plus d’impact sur la neutralité américaine. Nos résultats de recherche questionnent en fait la nature et la temporalité de la « neutralité » américaine. Est-ce réellement, comme le souhaitait au départ le président américain Wilson une « neutralité bienveillante », ou de la poudre aux yeux?

Objective To provide 2-year clinical- and patient-oriented data with regard to mandibular overdenture assisted by 2 immediately loaded unsplinted implants. Material and methods In this pre-post design, Phase-I clinical trial, 18 edentate individuals (62.4 ± 7.7 years) received a new set of complete denture. Then, following standard procedures, 3 threaded implants (OsseoSpeed TX™, Dentsply Implants, Mölndal, Sweden) were placed in the mandible in each patient, and locator abutments (Zest Anchors LLC, Escondido, U.S.A.) were inserted on the right and left side implants. The midline implant served as a control for within-patient comparison. The immediate loading was conducted within 24 h of surgery. Data were collected at baseline (T0), 12 (T1) and 24 (T2) months after immediate loading. The clinical outcomes included implant survival rate, crestal bone level changes and implant stability. These criteria were assessed through clinical and radiographic examinations as well as resonance frequency analysis. Patient-centered outcomes included patient satisfaction and oral health-related quality of life measured using validated questionnaires. Brunner-Langer approach was used for statistical analysis. Results Implant survival rate for immediate loaded implants was 91.7% at 2-year follow-up. None of the unloaded implants failed. There was no statistically significant difference at baseline and follow-ups with regard to clinical outcomes between loaded and unloaded implants. Patient satisfaction and quality of life improved (p < 0.0001) from baseline to 2-year follow-up. Conclusion Immediate loading protocol did not negatively affect clinical outcomes, satisfaction and quality of life of patients wearing 2-unsplinted-implant mandibular overdenture for 2 years. This conclusion requires confirmation by randomized control trials. Clinical significance statement Mandibular overdenture assisted by two immediately-loaded unsplinted implants is successful treatment based on 2-year clinical and patient-based outcomes.
