我国农村养老保险的现状及发展路径分析

农村养老保险的制度缺陷和资源稀缺严重阻碍农村经济的可持续发展和农民收入水平的提高,影响社会安定和社会公正,影响社会主义和谐社会的构建。因此,适时开展农村社会保障制度建设尤其是农村社会养老保险体系建设,是我国市场经济发展的客观需要,也是我们构建社会主义和谐社会的必要条件。

韩国的FTA战略

随着经济全球化的发展,国际贸易竞争日趋激烈。长期奉行“贸易立国”的韩国对外依存度极高,东南亚金融危机后,经济持续低迷。为抢占世界市场,缓解能源危机,扩大地区影响,韩国大力推行FTA战略。与多国展开FTA协商(谈判),争做世界贸易大国。设立专门机构,完善配套政策,使FTA走向制度化。韩国的FTA战略对我国不无借鉴意义。中国应尽快确立FTA战略,加强对FTA的系统研究,建立专门机构具体组织实施FTA战略。     

深圳地区大头金蝇年生长发育规律观察

目的观察深圳地区优势嗜尸性蝇种大头金蝇在尸体腐败分解过程中的发育历变化规律,并探讨其用于死亡时间推断的可能性。方法在调查深圳地区嗜尸性昆虫物种谱系的基础上,设置自然环境下的家猪尸体腐败模型,观察记录大头金蝇到达尸体、蝇蛆出现、大量出现、开始离食、大量离食、开始化蛹、大量化蛹,蛹开始羽化和大量羽化9个发育历期关键时间点。同时,收集处理成虫和幼虫,测量体长并模拟二元方程用于死亡时间推断。结果深圳地区不同季节中,大头金蝇在尸体上的生长发育具有规律性,蛆虫的离食时间点和羽化时间点对应的腐败分期在各个季节基本相同,前者基本处于腐败期,后者处于后腐败期。该地区四季蝇蛆长随死亡时间的变化模拟成二项式方程,分别为春季:y=-0.000 2x2+0.147 5x-0.925(R2=0.989 3);夏季:y=-0.001 4x2+0.316 6x-4.499 8(R2=0.970 1);秋季:y=-0.000 4x2+0.187 8x-1.107 9(R2=0.987 8);冬季:y=0.000 4x2-0.080 3x+4.367(R2=0.994 9)。结论大头金蝇在尸体上发育历期有一定的规律性,特别是蛆虫的离食时间点和羽化时间点对死亡时间推断的参考价值。     

Neighborhood Opportunity and Location Affordability for Low-Income Renter Families

Abstract

We use the Location Affordability Index (LAI) and the newly developed Child Opportunity Index (COI) to assess, for the first time, the tradeoff between neighborhood opportunity and housing/transportation affordability facing low-income renter families in the 100 largest metropolitan areas. In addition to describing the opportunity/affordability relationship, we explore the level of balance between neighborhoods’ relative cost burden and their corresponding opportunity levels to determine whether children of different racial/ethnic groups are more (or less) likely to experience cost-opportunity imbalance. Our multilevel analyses show that housing affordability is largely accounted for by the neighborhood opportunity structure within each metropolitan area. The metropolitan characteristics examined account for only a small proportion of the between-metro variance in the opportunity/affordability gradient for housing, presumably because the neighborhood opportunity structure already reflects metro area factors such as fragmentation and segregation. On the other hand, transportation affordability shows a weaker association with neighborhood opportunity. The COI/LAI association is much weaker for transportation than for housing, and a large part of the variation in the transportation gradient occurs at the metropolitan area level, not the neighborhood level. Sprawl is particularly associated with transportation affordability, with lower sprawl areas having lower transportation-cost burden. We discuss the implications of the empirical findings for defining affordability in housing assistance programs. We recommend that housing policy for low-income renter families adopt an expanded notion of affordability (housing, transportation, and opportunity) and explicitly consider equity (e.g. cost-opportunity imbalance) in the implementation of this expanded affordability definition.     

政治理论课多媒体技术运用存在的误区及对策

随着科技的进步,多媒体已经成为当今教学领域的热点,多媒体技术作为有效的辅助教学手段,在政治理论课教学中产生了积极的作用。然而,一些教师在制作与运用多媒体课件的过程中仍然存在一定的误区。文章就政治理论课教学中多媒体技术制作与运用中存在的误区及对策展开了探讨。     

禁止集体建设用地使用权进入房地产市场的正当性质疑

政府允许集体建设用地使用权流转却禁止其开发房地产,其理由不外乎是防止耕地流失、农村土地开发房地产与现行农村宅基地使用权制度相冲突、需要保持政府对房地产市场用地的垄断,这些理由并不充分和正当。从禁止所产生的后果来看,禁止也不具有正当性。政府在重新配置集体建设用地使用权时,要将公平与正义作为核心价值理念,充分尊重农民土地权益,平等对待国有、集体建设用地使用权,以实现城乡房地产市场的一体化发展。     

Statistical analysis of DNA mixtures using peak area information and allelic drop out

A case of a woman killed in Perugia is reported. The woman was beaten to death and the body showed evidence of bites, kicks and punches. The request of the Court was to verify the presence of bites and if they belonged to humans. Morphological examination and genetic analysis with human Y-specific markers were performed in order to verify the origin of the bites. The DNA profile from the surrounded area of the traces was compared with the profile of the victim's husband (the suspect).The results showed a match between the profile of the suspect and that of the traces for all loci examined. Due to the fact that also other relatives of the husband's male lineage lived in the same house, it was not possible to identify the man who really contributed to the traces. Therefore, the analysis was implemented with autosomal STR markers, which showed a mixed genetic profile. In order to verify the number and the identity of the contributors, statistical analysis based upon peak area information was performed with Probabilistic Expert Systems.     

父爱主义与“还地于民”

农村经济体制改革的进程就是一个“还地于民”的过程。因为流转上的障碍,农村土地权利并未真正物权化。流转管制背后蕴藏着父爱主义理念。父爱主义没有随着市场经济的发展而消解,反而重新抬头。但逻辑上父爱主义的预设前提并不存在,且潜伏着无效率和不自由的危险。父爱主义本质上是一种精英主义,土地管制所借助的三个正当化理由都有反思的必要。目前全球金融危机为“还地于民”提供了历史契机,摒弃父爱主义有助于实现农村土地资产彻底物权化和农民身份彻底市民化,并为克服危机提供动力。     

Lack of European Identity and the Failure of the Eurozone

Since late 2007, the Eurozone has been embroiled in a crisis that has seen GDP per capita stagnate, public debt soar, and unemployment reach record levels. This article argues that the Eurozone crisis will inevitably force fundamental changes in the structure of the EU. The only way to make the Eurozone work is through deeper fiscal integration of Eurozone economies. Yet wholesale fiscal integration cannot be achieved in the near term, due to the fact that EU citizens continue to identify more with their own nationalities than with Europe as a whole. The Eurozone economies of southern Europe will, therefore, continue to flounder, leading to further anti‐EU sentiment. Anti‐EU sentiment may eventually increase up to the point where one or all of these countries leave the Eurozone or the EU altogether. These propositions are supported with arguments from economic theory, and are bolstered by evidence from surveys and opinion polls.
