With the Obama Administration’s foreign policy pivot to Asia, the Chinese government is concerned about the possibility of new challenges in their foreign policy sphere of influence. Since the 1990s, many political and military analysts have explored the eventual rivalry between these two states. However, events in the Middle East preoccupy U.S. attention, leaving China moderately free in Southeast Asia, though it is uncertain for how long this will persist and if the United States will reallocate its attention to contain China. In this case, the Chinese government will need to develop countermeasures to sustain its geopolitical interests. There are two focuses in this analysis: (1) the Chinese geopolitical naval situation, exploring the problems in the geosphere surrounding China and the eventual competition with other regional powers and the United States in East Asia; and (2) the potential for space program cooperation with Russia and Brazil, which, in turn, dramatically changes the balance of power in outer space through positive aspects of Russian technical capabilities and strategic Brazilian geographic (Alcântara launch site). 相似文献

The article suggests that strategies for African engagement can no longer take sweeping views of the continent but need to differentiate policy responses. It also suggests that the real key to improving Africa lies with African leadership rather than external agencies and assistance. 相似文献

Coups d’etat continue to be common around the world, often leading to changes in leaders and institutions. We examine the relationship between military spending and coups and find that (i) successful coups increase military spending by more than failed attempts, and (ii) coups are more likely when military spending as a share of GDP is relatively low. Our identification strategy deals with the problem of reverse causality between coups and military spending by exploiting the conditional independence between a coup’s outcome and the change in military spending that follows it. We interpret our results as evidence that the military may stage coups in order to increase its funding, and rule out several alternative explanations. 相似文献

Abstract: Often carrion decomposition studies are conducted using a single carcass or a few carcasses sampled repeatedly through time to reveal trends in succession community composition. Measurements of biomass and other abiotic parameters (e.g., temperature) are often collected on the same carcasses but are rarely a focal point of the studies. This study investigated the effects that repeated sampling during experiments have on the decomposition of carrion, measured as both gross biomass (carcass plus fauna) and net biomass (carcass only), on carcasses disturbed on every visit (with weighing only or also with the collection of fauna) and on carcasses disturbed only once. Each trial lasted at least 21 days, with samples taken in triplicate. Rat carcasses used in this study were placed in the field on the same day and either weighed on every visit or ignored until a given day. Internal and ambient air temperatures were recorded on each carcass at the time of sampling and on undisturbed carcasses using temperature loggers. The presence of succession fauna did not result in significant biomass loss on most days; however, there were individual days early in decomposition (days 3 through 6) when the succession fauna comprised a large portion of the gross biomass. With the exception of biomass loss by the emigration of maggots on days 4 and 5, neither repeated weighing of the carcasses nor repeated weighing and faunal sampling of the carcasses statistically affected the rate of biomass loss. Internal temperatures of carcasses sampled repeatedly were frequently 2–5°C lower than those that had not been disturbed, and ambient temperatures differed significantly depending on the location of measurement device. Results indicate that methods used historically for biomass loss determination in experimental forensic entomology studies are adequate, but further refinements to experimental methodology are desirable. 相似文献

Bloodstain pattern analysis can be critical to accurate crime scene reconstruction. However, bloodstain patterns can be altered in the presence of insects and can confound crime scene reconstruction. To address this problem, we conducted a series of controlled laboratory experiments to investigate the effect of Lucilia sericata (Meigen) on impact bloodstains and pooled bloodstains in association with three combinations of common surfaces (linoleum/painted drywall, wood floor/wallpaper, and carpet/wood paneling). L. sericata fed from the pooled bloodstains and added insect stains through regurgitation and defecation of consumed blood. L. sericata formed defecatory trails of insect stains that indicated directionality. Defecatory stains fluoresced when viewed at 465 nm with an orange filter. These observations differed from Calliphora vicina insect stains because feeding on blood spatter was not observed and trails of insect stains were formed by L. sericata. The fluorescence of defecatory stains can be used as a method to detect insect stains and discriminate them from real bloodstains. 相似文献
