新疆教育的反非传统恐怖功能

20世纪90年代以来,新疆境内外民族分裂势力、宗教极端势力、暴力恐怖势力制造了大量的传统恐怖犯罪活动和非传统恐怖犯罪活动,新疆＂7.5＂事件所呈现的参与犯罪人数多、使用棍棒和石头做武器、大量普通群众遭遇袭击、造成恐慌的反人性非传统恐怖,严重地影响了新疆乃至全国的安全与稳定,这对包括教育学在内的人文社会科学研究提出了新的...     

美国的特别区治理与公共服务提供

特别区是美国地方政府中一种独特类别,它们为居民提供单一、专门化的公共服务。随着公共事务日益复杂化,特别区逐渐成为美国最普遍的地方政府形态,通过建立特别区来为公众提供公共产品和服务也成为美国地方治理的一个鲜明特色。了解美国特别区的历史演变、特别区公共服务提供的逻辑原理、它们的功能与性质,以及特别区背后的理论争议,对于我国的公共服务提供具有一定的启发性价值。     

阿富汗问题与上海合作组织

阿富汗问题是影响欧亚大陆国际战略以及地区安全格局的一个焦点问题,也始终是上海合作组织客观上难以回避的一个重大现实问题。近年来,美国奥巴马政府的阿富汗战略展开重大调整,但阿富汗局势及其对中亚安全形势的影响再趋严峻,上海合作组织对阿富汗问题的政策和作为也日益凸显出其重要性和迫切性。上海合作组织必须推出与时俱进的阿富汗问题新战略。上海合作组织在阿富汗问题上的政策取向主要从改善安全环境、推进政治和解、参与经济和社会重建、加强国际合作四方面入手。在阿富汗问题上上海合作组织可以有所作为,但要恰当定位,把握好度,循序渐进。     

Investigation of trace inorganic elements in street doses of heroin

Sixteen trace elements found in 309 street heroin samples, piped water and contaminated water were determined using inductively coupled plasma-mass spectrometry. All the street heroin samples were found to contain high levels of sodium, a reflection of the use of sodium bicarbonate during heroin synthesis. Additionally, this element was also found to be one of the potential contaminants acquired from the piped water. Calcium could be derived from lime while iron, aluminum and zinc could have come from the metallic container used in the processing/cutting stage. The levels of these elements remained low in the heroin and it could be due to the dilution effects from the addition of adulterants. Statistical validation was performed with six links of related heroin samples using principal component analysis to find the best pretreatment for sample classification. It was obtained that normalization followed by fourth root showed promising results with 8% errors in the sample clustering. The technique was then applied to the case samples. Finally, the result suggested that the case samples could have originated from at least two major groups respectively showing unique elemental profiles at the street level.     

美国外交政策周期理论:视角、述评与现实检验

考察美国立国以来的外交政策演变轨迹的视角大体上有两种:一是阶段性演化视角,认为美国外交政策运行呈现出一种阶段性变化的演化轨迹;二是周期视角(或曰钟摆视角),认为美国外交政策演变遵循一定的钟摆定律,在两种情绪或范式之间不断转换。在研究美国外交政策历史时,学界大都运用前一种视角而忽视后一种视角。自20世纪50年代起,美国学界开始对美国外交政策演变的周期性规律进行研究,形成了以法兰克·克林伯格为代表的"内向—外向"情绪交替理论、迈克尔·罗斯金的"干涉主义—非干涉主义"范式转换理论以及杰克·霍尔姆斯的"情绪/利益"理论。美国外交政策周期理论既有学理价值,又存在难以克服的不足。研究该理论对于了解美国外交政策的演变规律、认清当前美国外交政策所处的周期阶段及其对华政策的影响均具有重要的现实意义。     

浅谈侦查理念创新

侦查理念是侦查理论研究和侦查实践活动的指导性观念。侦查理念创新,必须牢固树立科学发展侦查理念、以人为本侦查理念、法治化侦查理念、信息化侦查理念;侦查理念创新,必须坚持与时俱进、立足国情、法律至上、侦查为民的原则。为实现打击犯罪和保障人权,维护社会和谐稳定的目标,阐明了侦查理念创新的社会价值。     

The Rise of Public–Private Partnerships in China: An Effective Financing Approach for Infrastructure Investment?

The rise of public‐private partnerships (PPPs) in China has spurred heated debates about their purpose and effectiveness. This article traces the fluctuation of China's PPPs over several decades and finds that PPPs have played a supplementary role in China's infrastructure investment, as a response to the pressures of fiscal shortfalls and government debts. The resurgence of PPPs in recent years aims to bridge the infrastructure gap and alleviate ballooning local debts. These expectations, however, are hard to realize. China's PPPs mainly involve state‐owned enterprises and place increasing financial burdens on the government. The central government has taken measures to attract private sector investment to mitigate the financial risk, but the prospects for PPPs remain unclear.     

石油企业改革发展与核心价值观重塑

在石油企业迈向国际化的成长发展中,新常态、低油价、安全环保、制约生产因素增多,新体制、新问题、新矛盾也日益显现,企业员工的人生观、价值观也更加多样复杂。要推进石油企业体制机制改革,就必须构建符合石油企业改革发展需要的价值体系。构建石油企业核心价值观体系,必须坚持社会主义核心价值观在企业意识形态领域的主导地位,把握好重塑企业核心价值观的切入点,遵循价值观念形成的规律。
