对农传播中的农民权益问题:基于受众本位论的分析

我国对农传播中农村居民的受众角色与地位一直是人们关注和探讨的问题。从受众本位论的角度来看,农村居民的受众角色获得及受众权利保障既具有可能性又具有必要性。在目前我国对农传播中农村居民受众角色缺席的背后,实际上是媒体责任和政府义务的双重缺位。承认且保障农村居民受众权利,本质上是对其公民权和公共物品选择权的尊重。实行多元治理与商业逻辑的协商与共谋,是确立农村居民受众地位和提高对农传播效果的必然之路。     

甲胺磷在犬体内的死后分布

目的建立甲胺磷的犬灌胃染毒致死模型,观察甲胺磷在犬体内的死后分布规律。方法犬经8倍LD50（7.4mg/kg）剂量甲胺磷灌胃后,观察其中毒症状,死亡后即刻解剖,分别取心、肝、脾、肺、肾、脑、右上肢肌、右下肢肌、胸肌、胃组织、心血、胆汁、玻璃体液和尿液,GC/MS和GC法检测其中甲胺磷含量。结果犬8倍LD50甲胺磷灌胃染毒后20min内出现中毒症状（,53.3±14.1）min死亡。各组织脏器及体液中甲胺磷含量由高到低分别为胃（99.84±0.87）μg/g、脾（46.87±28.67）μg/g、肝（43.82±22.74）μg/g、肾（43.79±29.04）μg/g、心血（35.36±13.98）μg/mL、肺（35.25±18.59）μg/g、尿34.81μg/mL、胸肌（19.23±17.18）μg/g、右上肢（16.92±8.98）μg/g、心（15.09±6.11）μg/g、右下肢（12.83±7.63）μg/g、脑（10.91±4.13）μg/g、胆汁（6.75±1.45）μg/mL、玻璃体液（6.22±4.97）μg/mL。结论甲胺磷在犬体内死后分布不均,胃、脾、肝、肾、心血、肺、尿检材中含量较高,可作为疑似甲胺磷中毒毒物分析的检材。     

Characterization of Mitochondrial DNA Sequence Heteroplasmy in Blood Tissue and Hair as a Function of Hair Morphology*,†,‡

Abstract: This study characterizes mitochondrial DNA (mtDNA) sequence heteroplasmy in blood tissue and hair as a function of hair morphology. Bloodstains (127 individuals) and head hairs (128 individuals) were typed using the mtDNA LINEAR ARRAY? assay. A total of 1589 hairs were interpreted: 1478 (93%) were homoplasmic and 111 (7%) exhibited heteroplasmy at one or more positions. Seventy‐one percent (82/116) of individuals were homoplasmic, whereas 29% (34/116) exhibited heteroplasmy in at least one hair. The results demonstrate intra‐ and inter‐tissue differences in heteroplasmy within individuals. Sequence heteroplasmy among hairs from each individual varied from 0 to 90%; the frequency does not differ significantly with population group, cosmetic treatment, age, gender, medulla morphology, region of the scalp, hair growth phase, or, when comparing living and deceased donors. However, the results support a correlation between heteroplasmy and hair pigmentation; typically, lighter‐pigmented hairs exhibit a higher incidence of sequence heteroplasmy compared to darker hairs.

民营经济良性发展的着眼点在于城市管理的创新

近年来,我国民营经济得到了长足发展,但城市管理明显滞后,阻碍了民营企业的快速发展。其原因在于城市管理者的观念落后,职能转变不到位,政策不够完善,社会化服务体系不能满足民营经济发展的需要,民营企业自身素质不高等等。因此,以城市管理的创新来推动民营经济的良性发展是最佳选择。     

农村基层治理机制的创新实践与启示——基于浙江仙居横溪镇村干部"创业积分制"的调研

农村基层组织是党的工作和战斗力的基础。在新形势下,如何在总结各地实践经验的基础上,进一步完善符合中国国情的农村基层治理机制显得尤为迫切。而浙江仙居横溪镇的村干部创业积分制,就是在乡镇党委政府主导下,充分发挥农民主体参与动力以实现村两委(干部)主动创业的互动参与式乡村治理运行机制的构建。在多年的实践中,实现了乡镇党委政府赢信任、村两委(干部)创业绩、村民得实惠的多赢格局,发展了农村经济,维护了农村社会稳定。因此,这种植根于乡土社会的实践探索,无疑可以为中国乡村善治之路的理论资源和政治智慧的积累提供经验借鉴和实践样本。

加强和改进流动党员管理的难点及对策

加强流动党员管理既是一个热点问题,又是新形势下党建工作不容回避的难点问题。其难点主要表现为个体流动、行踪无常,党组织组建率低、稳定性差,管理机制滞后、管理渠道不畅,党务工作者队伍建设和管理弱化。要从根本上解决这些问题,必须实现思想、方法和网络上的统筹,推进城乡一体化党员动态管理。与此同时,还要建立健全流动党员教育管理信息网络建设机制,构建城乡一体化党员动态管理的保障机制,健全城乡党的基层组织互帮互助机制,培养建立稳定的党务工作者队伍。
