南海海洋设施渔业组织模式探析

邻国非法抢占中国南海岛礁资源和对资源的掠夺式破坏眭捕捞,致使中国南海渔业发展空间受限,严重影响了中国南海渔业的可持续发展。同时,邻国对南海主权的恶意挑衅,又严重威胁了我国南海渔业生产的安全。中国政府要进行南海维权,必须突出在南海的岛礁存在,发展海洋设施渔业,并探讨适应南海维权要求的海洋设施渔业的组织模式。本文设计的模式为：基于公共服务的国有公司模式,基于产业内的企业集团模式,基于产业间的战略联盟模式。     

The Effect of Housing on Perceptions of Quality of Life of Older Adults Participating in a Medicaid Long-Term Care Demonstration Project

Summary

As the nation struggles with the great increase in the numbers of older adults, many questions arise about how to provide housing and long-term care options that will ensure the quality of life of older adults. This study demonstrates that older adults and their families perceive quality of life more positively once moved from a nursing home to an assisted living facility using Medicaid funds. Results of this exploratory study are promising and suggest that having housing options available across the continuum of care with individualized case management offers older     

Risk Communication in the Real World

Rigorous health risk assessments of site-specific projects are generally little understood by nontechnical decision makers and the public and often appear to them to obfuscate a straightforward answer to their fundamental question: “Is the project safe?” The focus on risk, usually out of context of benefits, deprives the reader of the opportunity to make a fully informed decision on the proposal. While the risk assessment tools may need to be refashioned, confidence in the analytical process can be improved, partly through more citizen involvement, as well as through more effective communication of the conservatism of the assumptions, the thoroughness of the process, and the significance of the results in comparison to other commonly accepted involuntary exposures and risks.     

Approximation Algorithms for Bounded Facility Location Problems

The bounded k-median problem is to select in an undirected graph G = (V,E) a set S of k vertices such that the distance from any vertex v V to S is at most a given bound d and the average distance from vertices V\S to S is minimized. We present randomized algorithms for several versions of this problem and we prove some inapproximability results. We also study the bounded version of the uncapacitated facility location problem and present extensions of known deterministic algorithms for the unbounded version.     

A Parametric Approach for a Nonlinear Discrete Location Problem

A discrete location problem is formulated for the design of a postal service network. The cost objective of this problem includes a nonlinear concave component. A parametric integer programming algorithm is developed to find an approximate solution to the problem. The algorithm reduces the problem into a sequence of p-median problems and deals with the nonlinear cost by a node-replacement scheme. Preliminary computational results are presented.     

重庆市设施农业现状与问题分析

设施农业使有限的农业资源得到集约、高效的利用,能够大大提高农业效益与农产品质量,代表了现代农业的发展方向。目前,重庆市设施农业发展较快,但存在运行成本高、劳动生产率低、管理水平差、后续投入不足等诸多问题。基于重庆市特殊的自然环境和社会经济条件,重庆市应当合理定位,因地制宜地适度发展设施农业,加快相关科研工作,建立多渠道的投入体系,充分发挥其对推动农业结构调整、农民增收的示范和带动作用。     

基于时间满意的最大覆盖选址问题

传统的选址问题过于简单地考量时间这一对企业竞争力影响重大的因素,结合这一特点,本文对时间满意度函数进行了定义并提出了基于时间满意的最大覆盖选址问题。给定的网络G(V,A)中,在总的顾客对服务站响应速度的满意程度最大的目标下建立了最大覆盖选址问题模型,我们在讨论了问题的特点之后给出了基于拉格朗日松驰的启发式算法,并通过MATLAB进行了编程计算实验,分析了实验结果。     

Improving Australian Residential Aged Care Facilities: A Review of Minor Refurbishment Elements

The objective of this study is to identify elements pertaining to minor refurbishments of residential aged care facilities. A narrative review of relevant publications was conducted. Inductive content analysis was used to categorize coded data into major or minor refurbishment or staff practices. Further analysis identified minor refurbishment domains. There were 14 major refurbishment, seven minor refurbishment and two staff practices domains established. The minor refurbishment elements (n?=?7) identified were lighting, furniture, color and contrast, wayfinding, noise, signage, and flooring. Assessing these elements would assist residential aged care providers to prioritize the provision of minor improvements to the environment for residents.     

重大邻避设施决策风险评价的关系谱系与价值演进

重大邻避设施决策风险评价是一个体系,其中的经济评价、安全评价、环境评价和社会稳定评价虽然功能各异,但它们之间存在着内在的关联性。经济风险评价是基础,安全风险评价是保障,环境风险评价是深化,社会稳定风险评价是归宿。重大邻避设施决策风险评价体系的不断完善,本质上源自人们对生存不确定性的认识升华和价值演进,现实风险的类型及威胁程度影响着人们决策价值的选择方向与转换方式,从开发主义始,历经科学主义和生态环保主义,最终演进到包含环境正义观和后物质主义在内的邻避主义。     

单方拒绝交易的反垄断法规制问题

单方拒绝交易被认为是经营者滥用市场支配地位的行为,但支持反垄断法规制此类行为的"必要设施"理论是不充分的。规制单方拒绝交易行为和经营自主权有冲突,对经营者从事投资和创新的动机有负面影响,而且在救济措施方面也存在困难。美国反垄断法经过反复摸索已经放松了对拒绝交易行为的处理。中国反垄断法采取"过错推定"的做法,要求垄断经营者必须提供采取此类行为的正当理由,迫使垄断经营者承担了过多的法律风险,恰当的做法应当是"无罪推定"。
