Abstract:  为探讨高中生自杀意念的现状及影响因素,采用症状自评量表(SCL-90)、艾森克人格特征问卷(EPQ)、自杀意念发生率量表对重庆市14所高中10,384名学生进行问卷调查,发现:1) 重庆市高中生自杀意念低,自杀意念发生率为59.4%,自杀未遂率为2.6%。不同性别、来源高中生生自杀意念程度存在显著差异;不同性别、来源、年级高中生自杀意念发生率均存在显著差异。2) 忧郁、神经质、其他、强迫、敌对、人际、躯体、精神、内外向、精神质是高中生自杀意念的重要影响因素。建议学校在自杀预防与危机干预工作中加强对忧郁、情绪不稳定、饮食睡眠障碍、敌意、精神症状、内向、自我中心这类对象的关注。
To explore the status quo and the influence factors of senior high school students’ suicide ideation, 10,384 students who come from 14 high schools in Chongqing city were tested with the Symptom Check List (SCL-90), Eysenck Personality Questionnaire (EPQ) and the Incidence of Suicide Ideation Scale. The results were as follows: 1) The suicide ideation of senior high school students in Chongqing is low, the incidence of suicide ideation was 59.4% and the attempted suicide rate was 2.6%. There were significant differences for gender and backgrounds in the degree of suicide ideation of senior high school students; there were significant differences for gender, backgrounds and grades in the incidence of suicide ideation of senior high school students. 2) Melancholy, nervosity, others, compulsion, hostile, interpersonal relationships, physical symptoms, spirit, extroversion or introversion and psychoticism were the important factors on senior high school students’ suicide ideation. We suggest that suicidal prevention and crisis intervention should pay more attention to the students who are melancholy, low on emotional stability, have diet or sleep problems, hostility, psychotic symptoms, introversion,

 [PDF]

Abstract:
面对气候变化的严峻形势,我国在推进碳减排工作中制定了相关政策和实践。但是由于现行环境管理推进模式存在很多弊端,使得我国的碳减排工作困难重重。因此,我国必须探寻一种新型的碳减排制度,提高我国碳减排领域的效率,降低减排成本。国际社会上碳排放强度提出后,显示出其对经济增长和治理环境问题的重要作用。联合国气候大会上,我国政府提出了基于碳强度指标的自愿减排的目标。因此,本文采用规范分析方法,提出建立碳强度约束下的碳金融市场是我国应对气候变化的必然制度选择。最终得出结论,我国需要从特殊国情出发,将碳强度与碳市场进行有机结合,建立一个基于碳排放强度指标减排的碳金融市场。并需要在限定排放目标的基础上,明确买卖主体,完成碳强度指标与碳总量指标的转化,最终实现分行业、分地区的碳交易。
Face to the serious situation of climate change, China has made the related policies and practices in promoting carbon reduction work. But, the current environmental management advance mode has many disadvantages; it made the carbon reduction work hard. Therefore, China must explore a new type of carbon reduction system to improve the efficiency in the field of carbon emissions, and also reduce the costs. Now, the international community has raised carbon intensity reduction mode, and it has showed its important role in economic growth and governance facing to the en-vironmental problems. In the UN climate conference, the Chinese government has presented the carbon intensity of voluntary emission reduction targets. Therefore, the establishment of carbon financial market under the restriction of carbon intensity is the necessary choice in China using the standard analysis method. We need to start with special national conditions in China, combine the carbon intensity to carbon market, and finally create a carbon market based on carbon emission intensity target. And we need to clear trading bodies, complete the conversion of total carbon to carbon intensity index on the basis of defining emission targets, and ultimately complete industry and region carbon trade.
债券溢折价摊销的实际利率法

财会月刊 , 2008,
Abstract: 本文对企业债券发行实务中的具体数据进行了一般化的处理,并利用严密的数学推导,探讨了债券溢折价摊销的实际利率法的规律。  【关键词】实际利率法溢价摊销折价摊销企业会计准则要求对债券溢折价采用实际利率法进行摊销,这种方法是根据企业债券发行时的市场实际利率来计算每期利息费用,再与应付利息(票面利息)相比较,确定各期宜摊销的溢折价金额。然而,现有研究中几乎没有利用数学工具探求实际利率法一般规律和理论实质的文章,所以本文在一定程度上弥补了这方面理论研究的空白。笔者对具体数据做了一般化处理,通过严密的数学推导,得出实际利率法的规律和实质,便于读者对其有更全面、深入的了解。
庞德论中国法律:社会学法理学思想的一次应用

华东政法大学学报 , 2010,
Abstract: 1946年7月至1948年11月,罗斯科·庞德受聘担任了南京国民政府司法行政部和教育部顾问,帮助中国进行法制重建和司法改革。这段经历为晚年在思想上受到挑战的庞德提供了实践其理念的机遇。庞德对《中华民国宪法》草案的诊断,在某种程度上成为其理论体系盲点的注脚;但他对于中国法制的建言,贯彻了其社会学法理学的基本理念,其中的某些判断和建议,依然值得当代中国法律人借鉴和反思。
作为独立学科的考古学―――考古学、人类学、历史学学科体系之比较

东南文化 , 2001,
Abstract: ????关于中国考古学的学科归属问题一直存在着争议,一种意见认为考古学属于历史学的范畴;一种意见认为考古学应是人类学的分支学科之一。本文将考古学与历史学、人类学的学科体系加以比较,论述了在学科起源、研究内容、研究方法、研究对象、分支学科等方面,考古学与历史学和人类学的差异。从而认为考古学与人类学、历史学有极其密切的联系,但它作为独立学科的趋势是必然的。
国家、市场与牧民生计转变:草原生态问题的阐释——内蒙古巴图旗的案例研究

天府新论 , 2012,
Abstract: 纵观近十年来牧区现代化进程,国家和市场对牧民生计的影响重大.从宏观角度来看,国家推行的一整套现代化制度成为改造牧区的主要力量.从微观角度来看,牧民的放牧方式、牧业技术、生产组织等发生了很大转变.牧民逐渐成为追求利润的“小牧”,同时也承担着草原退化、沙化带来的环境风险.

Abstract:
综述了纳米CeO2的几种主要制备方法及其研究进展。对比分析了气相、固相、液相三种主要方法的优缺点,气相法所制备的样品纯度高、团聚小,但设备昂贵不易普及。液相法设别简单易普及但所制备的样品团聚严重,固相法工艺简单污染少但所制样品均匀性可控性较差。并对未来纳米CeO2制备方法的发展方向进行分析与展望。
Several main preparation methods of nano-CeO2 and their research progress are reviewed. The advantages and disadvantages of three major methods including gas phase, solid phase and liquid phase are analyzed and com- pared separately. Sample prepared by gas phase method has high purity and small reunion, but the expensive equipment makes it difficult to popularize. Liquid phase method is easy to popularize, but its sample has heavy reunion. The solid phase method has outstanding merits of simple production process and low pollution, while the uniformity of sample which prepared via this method is hard to control. The future directions of the preparation methods of nano-CeO2 are analyzed and prospected too.
