儿童性侵犯的犯罪心理分析及防治对策

对儿童性侵犯是一种性质极其恶劣的犯罪行为,会给受害儿童及其家庭带来深重的伤害。因此,如何有效地预防和制止这类犯罪,使我们的孩子免受伤害,是所有家长、教育部门、司法部门和公民应共同承担的责任。针对性侵犯对儿童的伤害、性侵犯者的类型及行为动机进行了心理分析,并在此基础上提出了防治对策。

A Probabilistic Approach to Assess External Doses to the Public Considering Spatial Variability of Radioactive Contamination and Interpopulation Differences in Behavior Pattern

Dose assessment is an important issue from the viewpoints of protecting people from radiation exposure and managing postaccident situations adequately. However, the radiation doses received by people cannot be determined with complete accuracy because of the uncertainties and the variability associated with any process of defining individual characteristics and in the dose assessment process itself. In this study, a dose assessment model was developed based on measurements and surveys of individual doses and relevant contributors (i.e., ambient dose rates and behavior patterns) in Fukushima City for four population groups: Fukushima City Office staff, Senior Citizens’ Club, Contractors’ Association, and Agricultural Cooperative. In addition, probabilistic assessments were performed for these population groups by considering the spatial variability of contamination and interpopulation differences resulting from behavior patterns. As a result of comparison with the actual measurements, the assessment results for participants from the Fukushima City Office agreed with the measured values, thereby validating the model and the approach. Although the assessment results obtained for the Senior Citizens’ Club and the Agricultural Cooperative differ partly from the measured values, by addressing further considerations in terms of dose reduction effects due to decontamination and the impact of additional exposure sources in agricultural fields, these results can be improved. By contrast, the measurements obtained for the participants from the Contractors’ Association were not reproduced well in the present study. To assess the doses to this group, further investigations of association members’ work activities and the related dose reduction effects are needed.     

中国共产党早期媒介批评实践与思想论略

中国共产党早期媒介批评是中国共产党媒介批评史的源头,它的产生在一定程度上是政治论战的结果和需要,受到蓬勃发展的中国现代新闻传播事业的润泽和苏俄党报理论的影响。回顾、检讨和批评党内在宣传领域的种种不正确的表现,对外国侵略者利用新闻媒体干涉中国主权进行文化侵略的揭露和批判,是中国共产党早期媒介批评的重要内容,其特色是长于从新闻报道的政治性、全面性、真实性角度分析新闻传播现象。     

常德"抗战碉堡"质疑

今常德城区及近郊存有多座旧式水泥碉堡,传为1943年常德会战中国军队抗击日寇所存留下来的"抗战碉堡",市政府计划拨款对其修葺保护,以作爱国主义遗迹供人景仰。但考察这些碉堡,没有战斗痕迹,并且常德会战后许多记录会战战况的书籍也没有关于这些水泥碉堡的记载,乃至日本方面的相关资料亦没有这些水泥碉堡的记载。另从有些资料看,今存这批水泥碉堡可能是1949年国民党军阻止中共军队南下所修建。

Competition and evolutionary stability of plants in a spatially structured habitat

We modelled the population dynamics of two types of plants with limited dispersal living in a lattice structured habitat. Each site of the square lattice model was either occupied by an individual or vacant. Each individual reproduced to its neighbors. We derived a criterion for the invasion of a rare type into a population composed of a resident type based on a pair-approximation method, in which the dynamics of both average densities and the nearest neighbor correlations were considered. Based on this invasibility criterion, we showed that, when there is a tradeoff between birth and death rates, the evolutionarily stable type is the one that has the highest ratio of birth rate to mortality. If these types are different species, they form segregated spatial patterns in the lattice model in which intraspecific competitive interactions occur more frequently than interspecific interactions. However, stable coexistence is not possible in the lattice model contrary to results from completely mixed population models. This clearly shows that the casual conclusion, based on traditional well mixed population models, that different species can coexist if intraspecific competition is stronger than interspecific competition, does not hold for spatially structured population models.     

我国野生动物外来物种入侵的法律应对——兼谈对环境法“调整论”反思的反思

为有效应对野生动物外来物种入侵问题,我国应当借鉴美、日等国家的有益经验,及时修改《野生动物保护法》等立法,健全完善由外来物种的分类管理、风险评估、引进和放生许可、监测预警、应急反应等组成的制度体系。同时,还应当修改《侵权责任法》,将生态破坏侵权纳入统一的环境侵权责任制度;修改《刑法》,创设破坏生态罪的新罪名。此外,还应推进行政监管体制改革,成立专司生态保育工作的生态部,并在其下设立生物多样性管理局,实现对生物入侵应对事宜的统一监管。从理论上看,研究应对外来物种入侵的法律调整机理,不仅有助于理解关于环境法可以调整“人-自然”关系之“调整论”的可贵之处,还有利于揭示“自然体权利论”和“非人类中心主义”等极端观点的谬误所在,进而修正和完善环境法“调整论”。     

高空抛物的法理分析

高空抛物伤人事件屡禁不止.舆论的谴责对不良行为者,只是隔山打牛,不痛不痒,没有强制约束力和制裁力,不是治本之策.相关法律理论的不成熟和法律的缺失直接导致受害者合法权益不能得到有效的保护,而且也致使法院在受理类似案件难以决断.因此,需要加强相关法律研究及有关法规的制订.
