Managing Health Care in Oregon: The Search for a Civic Bioethics

Managed health care deliberations in Oregon point to a "civic bioethics" model to resolve allocation issues through publicly articulated community values and priorities that influence legislative action. Communication practices in the Oregon experiment provide data to develop an evaluative framework to assess public moral deliberation in value-laden contexts such as health care distribution. The Oregon experience also points to dialogical virtues to heighten citizens' ethical sensibilities and political will, discursive tools to inform ethical communication practices in a civic bioethics model.

Child maltreatment reporting in the general population: Examining the roles of community,collective efficacy,and adverse childhood experiences

According to bystander theory, factors such as the community environment, collective efficacy, and history of adverse childhood experiences could be related to likelihood of reporting or intervening against maltreatment. An online survey was conducted with 946 general population Californians obtained through mixed-mode random probability and quota-based recruitment methods. Using an experimental vignette design, participants were randomly assigned to two scenarios: a) potential child abuse occurring in their neighborhood; b) potential child abuse in an unfamiliar neighborhood. Weighted multivariate logistic regression models assessed relationships between the vignette condition, collective efficacy, appraisal of the behavior, and likelihood of reporting or intervening. The results suggested that perceiving the vignette as occurring in your own neighborhood was associated with lower odds of viewing the behavior as appropriate and considering it abusive. Higher collective efficacy scores were associated with lower odds of viewing the incident as inappropriate but higher odds of personally intervening. Adverse childhood experiences were positively related to reporting the incident to child protective services and intervening. Bystanders may be more likely to give parents in their own neighborhood "the benefit of the doubt" by viewing their abusive behaviors as less severe, potentially leading to underreporting. Neighborhood collective efficacy might increase willingness to personally intervene, but not contact systems such as child protective services or police, suggesting that enhanced trust in communities does not extend to these institutions. Our findings have implications for neighborhood and education interventions to enhance understanding of and willingness to intervene on behalf of children.     

基于频度演化的领域知识关联关系涌现

领域知识的生长演化问题一直是图书情报学界重点关注的主题。以网络科学思维探索知识生长过程中的关联关系涌现问题,能够对知识关联的生长模式与机制进行揭示。本研究提取知识关联关系累计44万余对,关联频度87万余次,共划分为11个时间窗口。在对时间序列领域知识网络结构属性初步判识的基础上,对关联频度分布进行时间序列分析。并从领域知识生长过程中的关联频度数量、关联频度占比、邻近窗口状态等方面,对知识关联关系及其频度进行跟踪与分析。研究结果表明,知识关联关系生长过程中,关联关系频度的分布符合幂律分布,且在领域知识发展的成熟期表现得更好。知识关联关系的生长过程具有频度层面的“富者更富”的属性,且主要遵循“择优强化”机制。尽管研究所使用的基于社会化标注系统的知识网络尚不足以囊括所有类型的知识网络,但是基于频度演化的知识关联关系涌现模式与机制,有助于促进知识网络、知识生长等领域的研究工作,对于社交网络、传播网络、交通网络等研究不无裨益。图5。表4。参考文献30。     

Correlation analysis-based image segmentation approach for automatic agriculture vehicle

INTRODUCTION In recent years,harvesting crop by combine has become more and more popular in China.In2003,combines were used to harvest23%of rice and71%of wheat.The work described here is part of a pro-ject aimed at researching automatic combines who follow the cut-uncut edge of the crops automatically to reduce the driver’s fatigue from the intensive work.Much attention has been focused on vision-bas-ed automatic agriculture vehicle.Image segmenta-tion is the key to extracting the guida…     

中国农村土地权利冲突及制度生成

中国农村土地权利冲突问题实质上是中国政治、经济、法律、社会、道德、习惯等各种力量的冲突,冲突的复杂性造成了中国农村土地使用规则的不确定性。只有建立起农村土地“制度生成”的“公共议论场所”,让各种对立的权利和主张权利的力量和利益充分地博奕,才能从根本上化解权利冲突,生成制度,从而促进制度文明的进步。
