“人肉搜索”的法理思考

"人肉搜索"作为一种网络新兴事物与现象,根据其对象和涉及事件类型的不同,可分为公众人物涉公事件型、非公众人物涉公事件型、公众人物涉私事件型和非公众人物涉私事件型四种类型.从法律角度而言,四类"人肉搜索"对个人隐私的侵入程度,呈依次递增趋势.同时,"人肉搜索"事件中涉及的网络信息发布者、网络信息传播者、网站三方,各主体责任也有所不同.     

突出地域特色的植物科学与技术专业教学改革

培养富有创新精神和开拓能力,理论坚实并具有现代植物生产技能,能够献身生态重建和区域农业发展的应用型高级技术人才。以此作为专业教学改革的基础目标,通过教师队伍素质和水平培养提高,着力相关课程改革,坚持理论教学面对区域农业发展实际,跟踪农业技术发展前沿,强化具有就业市场竞争能力的专业技能培养,通过办学条件的改善,使富有地域特色的专业教学改革取得初步而又明显的成效。     

“人肉搜索 ”的作用、风险及其控制

＂人肉搜索＂这种由人工参与解答,通过机器算法获得结果的搜索机制,在利用现代科技发展过程中逐渐形成了自己的特色。＂人肉搜索＂对社会产生了广泛影响,一方面起到打击违法犯罪,监督政府官员,强化道德压力和为民排忧解难的社会积极作用;另一方面也存在侵犯隐私的隐患和暴力性风险。借助道德的力量和法律的控制手段规约＂人肉搜索＂,可以避免其可能产生的隐患,发挥人肉搜索的积极效应,促进其健康发展。

完善非法侵入计算机信息系统罪的几点思考

非法侵入计算机信息系统罪是信息时代产生的一种新型犯罪，我国刑法第285条对此作出规定。然而，该罪在罪名、犯罪客体和对象、犯罪主体、刑种和量刑、刑事管辖权等方面都存在一些立法缺陷。因此，从立法层面应规范罪名的表述．适当扩大犯罪对象的范围，增加单位犯罪主体．增加本罪的刑种，提高本罪的刑度，明确本罪的刑事管辖权。

Plant closures,precariousness and policy responses: Revisiting MG Rover 10 years on

With automotive plants being closed in Australia and western Europe, this article reflects on the employment status of ex-MG Rover (MGR) workers following the closure of the Longbridge plant in 2005. In particular, it draws on Standing's typology of labour market insecurity and uses a mixed-methods approach including an analysis of a longitudinal survey of some 200 ex-MGR workers, and in-depth interviews with ex-workers and policy-makers. While the policy response to the closure saw significant successes in terms of the great majority of workers successfully adjusting into re-employment, and with positive findings in terms of re-training and education, the paper finds significant challenges in terms of security of employment, income, job quality and representation at work years after closure. In particular, the paper posits that the general lack of attention to employment security at the macrolevel effectively undermined elements of a positive policy response over the longer run. This in turn suggests longer-term policy measures are required to address aspects of precariousness at work.     

Redesigning a Cellular Manufacturing System to Handle Long-Term Demand Changes: A Methodology and Investigation*

Cellular manufacturing systems have been proposed as an alternative to the job shop since they provide some of the operational benefits of a flow line production process, while retaining to some extent the flexibility of job shops. However, this must be balanced against the possibility of additional initial investments in equipment to form the cells and a certain loss in manufacturing flexibility, particularly in terms of the ability to deal with long-term demand changes. This paper presents a model-based heuristic cell system redesign methodology to deal with such demand changes. The methodology is validated and applied to system designs generated from several data sets published in the literature. Results show that different kinds of demand changes incur distinct kinds of costs. Further, characteristics of cell designs that can handle long-term demand changes at least cost are identified.     

A Review of Plant Specific PRAs

A large number of PRA studies have been completed for specific plants at specific sites. From these studies, taken individually or collectively, many significant insights have evolved into items important to risk and safety. The content of this paper is primarily based on the material contained in the EPRI funded review of five PRA studies: Big Rock Point, Zion, Limerick, Grand Gulf, and Arkansas Nuclear One. The first three were the utility sponsored studies publicly available at the time of project initiation while the other two were deemed representative of the NRC's RSSMAP and IREP programs respectively. The results of PRA studies are usually expressed in terms of core melt frequencies, radionuclide release frequencies, and frequencies of occurrence of different reactor accident consequences (e.g., early and latent fatalities) depending on the level of PRA. These subjects are prominently addressed in this paper. One of the results of a PRA study is identification of a relatively small number of accident sequences that represent the dominant contributors to core melt. An analysis of the salient features of the dominant accident sequences from eleven PRA's yielded a characterization of accident sequence categories discussed at some length. Impact of external events is discussed very briefly. Next to an explicit quantification of public risk or core melt frequency, the identification of specific safety concerns and the evaluation of possible solutions to implement risk management are probably the best recognized and most widely used applications of PRA. Several illustrative examples are briefly discussed. Human interactions are extremely important contributors to safety and reliability of the plants. A review of PRA studies concluded that it was necessary to account for five types of human interactions; some of which may mitigate while others may exacerbate an accident sequence.
