南方丝绸之路对大理的影响及当前的对策

大理历史悠久,文化灿烂,风光秀丽,古道纵横。过去南方丝绸之路对大理的经济、政治、交通、文化、宗教等有较大的影响,今天在国家"一带一路"的大战略背景下,大理应该怎么办,大理学院应该怎么办,这是当代学人的新课题。以古代南方丝绸之路为出发点,建议今天大理的"一带一路"定位为交往之路、人情之路。     

上海黄浦江两支流河流甲烷含量研究

甲烷是一种重要的温室气体,虽然目前大气中含量远小于二氧化碳,但排放增长率却大于后者.研究区域为上海市黄浦江支流苏州河和淀浦河,通过实验数据对比城郊春夏的甲烷排放的差异,探讨甲烷产生的机制及其与环境因子的关系,这将有助于研究河流甲烷排放对于环境变化的影响.研究结果认为河流甲烷主要来源于水中沉积物,其产生与水质、温度等因素相关;同时甲烷摩尔浓度与硝酸根离子质量体积比存在负相关性,与铵根离子质量体积比和有机碳质量分数存在正相关性.     

和谐边疆构建下的宗教渗透问题研究——基于对云南跨境民族的田野调查

通过对云南跨境民族地区的田野调查,该区域宗教渗透不仅没有停止,反而呈现出多样性、隐蔽性等特点。宗教渗透对跨境民族的国家政治认同等造成了严重破坏,对云南边疆社会的稳定构成了较大的威胁,成为了云南边疆地区非传统安全问题中最敏感、最复杂、最难解决的问题之一。抵御宗教渗透不仅要完善政府宗教管理能力、改善经济条件等,更要调动作为文化主体者的跨境民族自身的"文化自觉",以主动抵御宗教渗透。只有如此才是最有效的抵御宗教渗透举措,才最终有利于和谐边疆的构建。     

Reconsideration on Homogeneous Quadratic Riemann Boundary Value Problem

The homogeneous quadratic Riemann boundary value problem (1) with Hoelder continuous coefficients for the normal case was considered by the author in 1997. But the solutions obtained there are incomplete. Here its general method of solution is obtained.     

Empirical Test for Earnings Management of Top Managers＇ Change in Listed Companies

Top managers play a significant role on business decision in listed companies. The frequency of top managers＇ change is rather high all along. Whether those listed companies which top managers changed can really improve performances？ In this paper, we will discuss whether listed companies improve the financial index through earning management and give some advice on top managers＇ change in listed companies in China.

望江矶雨花台砾石层工程地质特性及形成机理

根据野外考察与实验资料，对南京雨花区望江矶的雨花台砾石层的工程地质性质作出初步评价认为该砾石层具有一定的固结性，较好的水稳性，较强的抗剪性，中低压缩性不同于现代松散的砂砾石堆积体，作者还运用沉积原理及风化理论对影响其工程地质性质的作用因素进行了探讨。

The Difference of the Pulmonary-Artery Pressure of the Migrants from Difference Elevation at the 4636 - 4907 m Altitude

Study Objective： To compare and analyze the changes of the pulmonary-artery pressure of the migrants coming from different elevation in the hypoxic environment of 4636 - 4907 m extreme altitude. To explore the susceptibility to hypoxic pulmonary-artery hypertension （PH） in the subjects from different altitude and profession. Methods： By using Color Doppler Ultmsonography （CDU）, measuring the pulmonary-artery pressure of 207 healthy men, who had continuously being lived and worked at the extreme altitude for more than six months, and then were divided into three groups according to their profession and the altitude of original living place. Results： There was a significant difference in the outcomes of pulmonary-artery pressure from the 3 groups. Conclusions： Altitude of original living place, labor intensity are some of factors that impact the pulmonary-artery pressure of the people who exposure to a hypoxic environment. The pulmonary- artery pressure of person without strenuously physical work experience was more sensitive to hypoxic surroundings than that of labor workers. It was not always the fact at an extreme altitude that the moderate altitude mountaineers were superior to other migrants from a lower altitude or plain. The higher PH was found in the groups of the moderate altitude mountaineers and labor workers. It is unlikely certain that one with PH would surfer from HAPE.
