We examine whether business groups' influence on cash holdings depends on ownership. Group affiliation can increase firms' agency costs or benefit firms by providing an internal capital market, especially in transition economies characterized by weak investor protection and difficult external capital acquisition. A hand-collected dataset of Chinese firms reveals that group affiliation decreases cash holdings, alleviating the free-cash-flow problem of agency *** ownership and control of listed firms moderate this benefit, which is more pronounced when the financial market is less liquid. Group affiliation facilitates related-party transactions, increases debt capacity and decreases investmentcash-flow sensitivity and overinvestment. In transitional economies, privately controlled firms are more likely to benefit from group affiliation than statecontrolled firms propped up by the government.

AIM: To evaluate the prevalence and characteristics of colorectal adenoma and carcinoma in an inner city Hispanic ***: We reviewed the reports of 1628 Hispanic patients who underwent colonoscopy at Howard University from 2000 to 2010. Advanced adenoma was defined as adenoma ≥ 1 cm in size,adenomas with villous histology,high grade dysplasia and/or invasive cancer. Statistical analysis was performed using χ2 statistics and ***: The median age of the patients was 54 years,64.2% were females. Polyps were observed in 489(30.0%) of patients. Adenoma prevalence was 16.8%(n = 273),advanced adenoma 2.4%(n = 39),and colorectal cancer 0.4%(n = 7). Hyperplastic polyps were seen in 6.6% of the cohort(n = 107). Adenomas predominantly exhibited a proximal colonic distribution(53.7%,n = 144); while hyperplastic polyps were mostly located in the distal colon(70%,n = 75). Among 11.7%(n = 191) patients who underwent screening colonoscopy,the prevalence of colorectal lesions was 21.4% adenoma,2.6% advanced adenoma; and 8.3% hyperplastic ***: Our data showed low colorectal cancer prevalence among Hispanics in the Washington DC area. However,the pre-neoplastic pattern of colonic lesions in Hispanics likely points toward a shift in this population that needs to be monitored closely through large epidemiological studies.

Portal hypertension is a common clinical syndrome, defined by a pathologic increase in the portal venous pressure. Increased resistance to portal blood flow, the primary factor in the pathophysiology of portal hypertension, is in part due to morphological changes occurring in chronic liver diseases. This results in rerouting of blood flow away from the liver through collateral pathways to low-pressure systemic veins. Through a variety of computed tomographic, sonographic, magnetic resonance imaging and angiographic examples, this article discusses the appearances and prevalence of both common and less common portosystemic collateral channels in the thorax and abdomen. A brief overview of established interventional radiologic techniques for treatment of portal hypertension will also be provided. Awareness of the various imaging manifestations of portal hypertension can be helpful for assessing overall prognosis and planning proper management.

本文报道在美国农业研究中心用臭氧在室内熏蒸和田间开顶熏蒸植物,用此饲养墨西哥豆瓢虫的实验,以及熏蒸后植物体内某些化合物含量变化的测定。结果表明,墨西哥豆瓢虫(Epilachna varivestis Mulsant)喜食臭氧(O_3)污染的植物,幼虫取食O_3污染植物后蛹显著重于取食未受污染植物所形成的蛹。根据豆瓢虫食性和植物体内糖含量的测定,可以认为,低浓度O_3污染导致植物体内糖含量的增加,是促使豆瓢虫取食量和蛹重增加的重要因素。

本文研究我国政府出台的经济刺激政策对企业投资效率的影响。本文以2004-2013年中国上市公司为样本、以"四万亿投资"政策为外部冲击,探讨了我国政府就应对金融危机出台的经济刺激计划对企业投资效率的影响、作用路径和经济后果。研究发现,"四万亿投资"政策导致企业投资效率下降,并且这种下降效应在刺激政策实施期间政府补贴增加的企业和银行贷款增加的企业中都更为明显,而较好的信息披露质量在一定程度上能缓和"四万亿投资"政策带来的投资效率损失。进一步分析发现,政策实施期间的企业投资对其后续几年的股票回报率有显著的负向作用。本文提供了我国政府出台刺激政策经济后果的证据,对于理解政府在市场经济中的角色有一定的帮助。
