This article considers three questions: 1) what progress has been made in achieving MDG1 targets?; 2) what challenges remain?; and 3) what more could and should be done? To examine these questions, the article assesses the progress of Southeast Asia in seeking to achieve MDG1. It argues that the region is 'on track' to achieve MDG 1 targets, although significant challenges such as inequality remain. Economic growth, significant structural change and incorporation into global value chains have contributed to MDG progress. However, this is a double-edged sword as exposure to global economic turbulence can increase. The longer-term reduction of poverty, inequality and social exclusion is a question of empowerment of local producers within value chains-a shift in economic power and control through pro-poor strategies strong enough to effect substantive structural change. The article outlines key concepts; identifies the main characteristics of Southeast Asian poverty; outlines what more needs to be done; and concludes by reprising the article's findings and weighing the prospects for 2010-15 and beyond. 相似文献

C.E.R.A. (Continuous Erythropoietin Receptor Activator) is a new third-generation erythropoiesis-stimulating agent that has recently been linked with abuse in endurance sports. The anti-doping community rapidly reacted by releasing a high-throughput screening ELISA allowing the detection of C.E.R.A. doping in athletes' blood. In order to return adverse analytical findings, anti-doping laboratories, however, need, as far as possible, to confirm the presence of the drug in athletes' samples through orthogonal methods. This article focuses on the comparison of 2 proposed confirmation assays based on gel electrophoresis that were coupled with a new sample immunopurification method. IEF, the classical method used to target erythropoietin (EPO) and its recombinant analogues in athletes' samples, and SARKOSYL-PAGE were applied to the plasma samples of subjects having received a single injection of C.E.R.A. It was demonstrated that SARKOSYL-PAGE was at least 6 times more sensitive than IEF, with comparable specificity. A longer detection window coupled with easier interpretation criteria led us to recommend the use of SARKOSYL-PAGE to confirm C.E.R.A. presence in athletes' blood. 相似文献

Does partisan conflict damage citizens’ perceptions of Congress? If so, why has polarization increased in Congress since the 1970s? To address these questions, we unpack the “electoral connection” by exploring the mass public's attitudes toward partisan conflict via two survey experiments in which we manipulated characteristics of members and Congress. We find that party conflict reduces confidence in Congress among citizens across the partisan spectrum. However, there exists heterogeneity by strength of party identification with respect to evaluations of members. Independents and weak partisans are more supportive of members who espouse a bipartisan image, whereas strong partisans are less supportive. People with strong attachments to a political party disavow conflict in the aggregate but approve of individual members behaving in a partisan manner. This pattern helps us understand why members in safely partisan districts engage in partisan conflict even though partisanship damages the collective reputation of the institution. 相似文献

Animals may be responsible for an array of potentially lethal injuries. Blunt force injuries characteristically involve larger animals such as cattle or horses that may kick, crush, or trample a victim causing head and facial injuries. Farm workers in particular are at high risk of lethal injuries involving the head and torso. Significant blunt trauma may be found in vehicle occupants after collisions with large animals such as camels or moose. Rarely, zookeepers may be crushed by particularly massive animals such as elephants. Sharp force injuries usually involve carnivore bites, most often from dogs with a "hole and tear" pattern of wounding. Injuries from animals such as alligators and sharks may have a significant component of crushing. Incised wounds may result in death from exsanguination and air embolism. On occasion, blunt or sharp trauma from animal activity may be confused with postmortem damage or with inflicted injury from an assault. 相似文献

When compared with simultaneous lineup presentation, sequential presentation has been shown to reduce false identifications to a greater extent than it reduces correct identifications. However, there has been much debate about whether this difference in identification performance represents improved discriminability or more conservative responding. In this research, data from 22 experiments that compared sequential and simultaneous lineups were analyzed using a compound signal-detection model, which is specifically designed to describe decision-making performance on tasks such as eyewitness identification tests. Sequential (cf. simultaneous) presentation did not influence discriminability, but produced a conservative shift in response bias that resulted in less-biased choosing for sequential than simultaneous lineups. These results inform understanding of the effects of lineup presentation mode on eyewitness identification decisions. 相似文献

This paper examines innovation among very small firms and provides new insights into both internal and external determinants of patenting. Applying a non-linear panel data approach to about 160,000 observations on manufacturing firms in Sweden for the period 2000?C2006, the following facts emerge: (i) in contrast to larger firms, innovation in micro firms with 1?C10 employees is not sensitive to variation in internal financial resources, (ii) skilled labour is even more important for innovation among micro firms compared to other firms, (iii) affiliation to a domestically owned multinational enterprise group increases the innovation capacity of small businesses, (iv) small firms?? innovation is closely linked to participation in international trade and exports to the G7-countries, and (v) there is no statistically significant evidence that proximity to metropolitan areas, or presence in a specialized cluster, increases the innovativeness of the smallest firm. 相似文献
