论大学生权利的维护

高校享有办学自主权,但这并不意味着高校可以任意处分学生,新《普通高等学校学生管理规定》的颁布,使学生原本被限制和剥夺的一些法定基本权利得到了保护。学生合法权益的维护直接关系到高校的稳定,围绕学校和学生纠纷争议的逃课和作弊两大热点问题,就学校制定的一些不利于学生权利维护的校纪校规进行剖析,提出大学生权利维护的教育申诉制度和教育行政诉讼途径。     

新闻职业伦理四大争议问题评析

本文基于伦理和道德问题的分殊,重点探究当代新闻伦理四个基本问题。本文认为,在当今的全球化时代,许多社会基本问题充满了伦理争议,对于深刻影响社会的新闻传播职业来说,情况尤其是如此。如果说人们对于虚构造假、漠视生命等新闻职业道德问题通常可以明辨是非的话,那么新闻传播职业伦理问题则复杂得多,而且即便经过百家争鸣式的讨论,也难以求得一致意见。但是,我们通过这种以反思批判为特征的讨论,至少可以建立这样的共识:伦理思考和争论是一种极好的思维和表达训练,它对新闻从业者个人人格的完善、职业伦理以及公共伦理的养成和发展都是至关重要的。     

京津风沙源治理工程效益分析

国家林业局经济发展研究中心对京津风沙源治理工程进行了连续7年的跟踪监测,结果表明：京津工程进展顺利,工程在林业建设、农业措施、水利设施以及生态移民等方面的任务完成情况良好。但是,工程建设也面临一些问题：缺少管护经费、林牧矛盾突出、林业产出缺少政策扶持等。针对以上问题,提出增加管护经费、调整工程规划等政策建议。     

维权话语与抗争逻辑——中国农村群体性抗争事件研究的回顾与思考

从理论发展的角度来看,中国农村群体性抗争事件的研究围绕着农民维权话语的建构和农民群体性抗争模式总结两条主线展开。转型时期农民平等权的缺失成为维权话语建构的社会基础。在农民维权的大背景下,学术界对农民的群体性抗争行为进行了总结,提出“日常抵抗”、“依法抗争”、“以法抗争”、“草根动员”和“依势博弈”等五种抗争模式。本文在回顾五种抗争模式的基础上对各种模式存在的问题做了分析和说明。并就农村群体性抗争事件研究中存在的问题进行了思考。     

Random effects models for operational patient pathways

Patient flow modeling is a growing field of interest in health services research. Several techniques have been applied to model movement of patients within and between health-care facilities. However, individual patient experience during the delivery of care has always been overlooked. In this work, a random effects model is introduced to patient flow modeling and applied to a London Hospital Neonatal unit data. In particular, a random effects multinomial logit model is used to capture individual patient trajectories in the process of care with patient frailties modeled as random effects. Intuitively, both operational and clinical patient flow are modeled, the former being physical and the latter latent. Two variants of the model are proposed, one based on mere patient pathways and the other based on patient characteristics. Our technique could identify interesting pathways such as those that result in high probability of death (survival), pathways incurring the least (highest) cost of care or pathways with the least (highest) length of stay. Patient-specific discharge probabilities from the health care system could also be predicted. These are of interest to health-care managers in planning the scarce resources needed to run health-care institutions.     

On the comparison of the Fisher information of the log-normal and generalized Rayleigh distributions

Surles and Padgett recently considered two-parameter Burr Type X distribution by introducing a scale parameter and called it the generalized Rayleigh distribution. It is observed that the generalized Rayleigh and log-normal distributions have many common properties and both distributions can be used quite effectively to analyze skewed data set. In this paper, we mainly compare the Fisher information matrices of the two distributions for complete and censored observations. Although, both distributions may provide similar data fit and are quite similar in nature in many aspects, the corresponding Fisher information matrices can be quite different. We compute the total information measures of the two distributions for different parameter ranges and also compare the loss of information due to censoring. Real data analysis has been performed for illustrative purposes.     

论抵押权实现的非讼程序构建

《物权法》对抵押权实现做出了不同于《担保法》的规定。该法第195条第2款直接规定了抵押权人在达不成实现方式协议时,可以请求法院拍卖变卖抵押物。但这个创新性的民事实体法条文,究竟该适用我国民诉法中何种程序,目前还处于争议状态。从民诉法理论分析和比较法角度看,抵押权实现应当适用民事非讼程序,而非讼程序的制度构建正是文章的重点。      

Tracing ‘driver’ versus ‘modulator’ information flow throughout large-scale,task-related neural circuitry

Primary objective: To determine the relative uses of neural action potential (‘spike’) data versus local field potentials (LFPs) for modeling information flow through complex brain networks. Hypothesis: The common use of LFP data, which are continuous and therefore more mathematically suited for spectral information-flow modeling techniques such as Granger causality analysis, can lead to spurious inferences about whether a given brain area ‘drives’ the spiking in a downstream area. Experiment: We recorded spikes and LFPs from the forelimb motor cortex (M1) and the magnocellular red nucleus (mRN), which receives axon collaterals from M1 projection cells onto its distal dendrites, but not onto its perisomatic regions, as rats performed a skilled reaching task. Results and implications: As predicted, Granger causality analysis on the LFPs—which are mainly composed of vector-summed dendritic currents—produced results that if conventionally interpreted would suggest that the M1 cells drove spike firing in the mRN, whereas analyses of spiking in the two recorded regions revealed no significant correlations. These results suggest that mathematical models of information flow should treat the sampled dendritic activity as more likely to reflect intrinsic dendritic and input-related processing in neural networks, whereas spikes are more likely to provide information about the output of neural network processing.     

继承法上配偶法定居住权立法研究

我国《继承法》在配偶继承利益保护中存在制度性设计缺陷,与当代各国逐步提高配偶的继承地位、扩大配偶的继承份额的继承法发展趋势不符.两大法系很多国家的立法都规定配偶对婚姻住房享有居住权或优先权.法国、美国关于配偶居住权的规定对配偶生存利益的保护较为周全,值得我国借鉴.我国继承法修改过程中,应明确配偶对婚姻住房享有法定居住权,并对生存配偶法定居住权的成立要件、必要限度、权利丧失情形等方面作出详细规定,从而在切实保护配偶继承利益的同时实现继承人利益的平衡.     

大数据时代的意识形态话语权：挑战及应对

大数据作为一场深刻的社会变革产生了巨大影响,相关关系与混杂性的凸显,海量信息与交换方式的多样化等替代了因果关系,弱化了精确性、客观性以及真理的唯一性,改变了人们的认知模式和交往方式,消解了人们对于主流意识形态的认同。不仅如此,大数据的应用促进了互联网的开放性和各种自媒体的发展,为多元思潮、多元文化和多元意识形态的发展与竞争提供了更大的空间,给我国主流意识形态及其安全带来了很大挑战。认真研究大数据产生的影响,强化意识形态观念,利用大数据及各种新兴媒体与互联网,加强我国主流意识形态建设,以马克思主义意识形态和社会主义核心价值观整合和引领多元思潮、多元文化和多元意识形态,增强主流意识形态的感染力与指导作用,为习近平新时代社会主义事业提供坚强思想基础和政治保障,是一项必须完成的重要任务。
