Fatal Case of Hydrophilic Polymer Emboli

Hydrophilic polymers are used to coat catheters and other intravascular devices. In general, these polymers have many salutary properties; however, in some instances, fragmentation of hydrophilic polymers coating intravascular devices can occur with fatal consequences. This report details the histopathologic changes in the lung seen following polymer fragmentation and embolization from a central venous catheter. Polymer emboli detected microscopically are intravascular and consist of basophilic, lamellated, and nonrefractile elements. Typically, an inflammatory response is present to a variable degree. Embolization can result in severe tissue injury with ischemia and infarction.     

Comparative Journal Ratings: A Survey Report

The expert survey and bibliometric methods of assessing the quality of work in political science are complementary. This project builds on previous surveys of academic political science journals conducted among US political scientists. The current wave extends the survey to political scientists in Canada and the UK. Preliminary results suggest both similarities and differences across the three countries. These results matter for policy debate in any country that is considering channelling flows of funds to universities in proportion to the quality of their research, and in helping to supply objective evidence about the research quality of work submitted by candidates for academic appointments and promotions.     

美中关系展望

中美关系是成熟、广泛、建设性和坦率的.双方知道如何处理一系列广泛问题才能使其不损害总体关系.但不幸的是,每一方仍对对方的长期意图存有疑虑.在2009年,双方仍须审慎对待既有的主要问题.但随着一个重要变化的出现,最重大的全球问题也正上升至美中关系的核心地位.其中最关键的两个问题分别是全球经济危机以及清洁能源和气候变化问题.美国希望大力加强与中国在这两大问题上的磋商与合作.这类合作可以把美中关系推进到一个新阶段,即两国关系更深入、更稳定、对世界其他地区更重要.随着时间的推移,这种合作还可以减少相互间对对方长期意图的疑虑.如果两国付出了努力,却在这些重大全球问题上未能展开合作,那么美中之间的不信任感或许会加深,两国关系或许会面临新的困难.     

China's Foreign Military Relations with Asia‐Pacific

The People's Liberation Army has always had a significant role in shaping and implementing the People's Republic of China's foreign policies. Over the past two decades, the PLA's role has increased considerably, and is likely to become even more important in the future as China develops its military capabilities and casts a broader shadow in the Asia‐Pacific region. The PLA's foreign relations program has several goals: to shape the international security environment in support of key Chinese national security objectives; to improve political and military relations with foreign countries; to enhance China's military and defense industry modernization; to provide military assistance to countries in the developing world; and, to acquire knowledge in modern military doctrine, operations, training, military medicine, administration, and a host of non-combat related areas. The PLA seeks to accomplish these goals through its military attache´ offices abroad and the use of an elaborate system of bilateral exchanges. Of these programs, the most visible relations involve high-level visits, functional exchanges, arms purchases, and ship visits.     

Dilemmas and Disappointments: Progressive Politics 1896–2016

Attempts at a Labour–Liberal Democrat Progressive Alliance came to nothing prior to the 1997 general election. The original idea of progressivism, first mooted in Britain in 1896, was an American one. Suggestions for a progressive alliance in the UK came from Lloyd George in 1914, and then again in 1931, each time with little effect. Nothing emerged after 1945 until the Lib–Lab pact negotiated by Callaghan and Steel in 1977, which led to electoral misfortune for both and the rise and fall of the SDP. In 2010 a coalition between the Lib Dems (under Clegg) and the Conservatives was always much the more likely option. Most Labour people no longer saw the Lib Dems as a party of the left. The Coalition Agreement in 2010 showed the idea of an alliance to be a centrist, elitist one with little grass‐roots support. Such an alliance would flourish through abstract pressure groups rather than popular democracy, especially with a Labour party led by Corbyn. In the US and the UK, progressivism went badly wrong in its politics: Theodore Roosevelt's New Nationalist campaign of 1912 divided American reformers fatally, as did Lloyd George's postwar Coalition in Britain after 1918. Now, even after Brexit, a progressive alliance seems further away than ever. The story of the ‘Progressive Dilemma’ remains one of unrealistic projects, invariably disappointed.
