基于Agent模型的生态公平指数构建与模拟

伴随着社会经济的发展,社会公平逐渐成为热点话题。社会公平问题不但体现在社会现象上,还对生态系统起着重要的影响。通过构建资本交换自主体模型,模拟社会财富分配动态过程,可观测资本交换熵指数变化情况,从而解释熵增原理。除此以外,不同系统的最终状态能达到的最大熵指数不同,用熵增原理与本文构建的最大熵指数模型可以对系统的生态公平进行纵向或横向评价。构建的资本交换熵模型也可以证明最大熵原理,同时,财富集中的现象将会使生态环境的选择权完全交予富人群体,影响可持续发展。     

Age‐related inequalities in health and healthcare: the life stages approach

How should healthcare systems prepare to care for growing numbers and proportions of older people? Older people generally suffer worse health than younger people do. Should societies take steps to reduce age‐related health inequalities? Some express concern that doing so would increase age‐related inequalities in healthcare. This paper addresses this debate by (1) presenting an argument in support of three principles for distributing scarce resources between age groups; (2) framing these principles of age group justice in terms of life stages; and (3) indicating policy implications that merit further attention in light of rapidly aging societies.     

Should Persons Detained During Public Health Crises Receive Compensation?

One of the ways in which public health officials control outbreaks of epidemic disease is by attempting to control the situations in which the infectious agent can spread. This may include isolation of infected persons, quarantine of persons who may be infected and detention of persons who are present in or have entered premises where infected persons are being treated. Most who have analysed such measures think that the restrictions in liberty they entail and the detriments in welfare they impose can be justified and this paper proceeds from the assumption that detention measures are justifiable in some circumstances. Such measures are often implemented without any compensation being given to the persons who are detained. This raises the question: What do we owe to those whose liberty is justifiably restricted (e.g. through isolation, quarantine or detention) as a public health measure during a public health emergency? More specifically, do we owe them compensation for any losses they experience? The paper falls in four main sections. The first section provides examples of the current regulatory state of affairs from the US, Canada and WHO. The second section lays out the liberal, welfarist and pragmatic arguments for providing compensation. The third section discusses the arguments against compensation and the fourth and final section provides the conclusion. It is argued that the arguments for providing compensation clearly outweigh the counterarguments and that the default public policy therefore should be that compensation is provided.     

Organ Donation: Who Should Decide?—A Canadian Perspective

This paper examines an under-explored issue in organ donation: whose decision making authority should be privileged posthumously in the context of known, explicit consent for donation? Current practices in Canada support the family as the ultimate decision maker, despite the existence of legislative support in many Canadian provinces for the potential donor as legitimate decision maker. Arguments for and against privileging the family and the potential donor are identified. Informing the question of “who should decide” are considerations of individual and relational autonomy, distributive and social justice, personhood, and arguments “from distress”. Tensions and competing obligations emerge from an exploration of these considerations that call for further, inclusive dialogue and deliberation on this important organ donation issue.     

Generating power: gender,ethnicity and empowerment in India's Narmada Valley

Current analyses of issues relating to ethnicity and empowerment are silent about the significance of the environment in shaping and being shaped by human relations. For its part, environmental policy research, with few exceptions, has also ignored the dynamics of identity construction and cultural values that inform human relationships with the environment and thus affect environmental sustainability. I address this gap in the scholarship through an analysis of the Sardar Sarovar Project [SSP] in India. I explore the interweaving of the constructions of gender, ethnicity and empowerment and their implications for a new politics of the environment - the politics of environmental justice. I argue that discourses of modernization underpin the arguments of all those who discuss the SSP, whether in favour or against.     

The 1985 guinea/guinea‐bissau maritime boundary case and its implications

The 1985 Guinea/Guinea‐Bissau maritime boundary case was a landmark decision in maritime delimitation. For the first time, sub‐Saharan African states resorted to third‐party settlement, thereby making a significant contribution to the developing state practice on maritime delimitation. The Arbitration Tribunal took an unprecedented “regional approach,”; which had a direct effect on the two neighboring countries, Senegal and Sierra Leone. The Award provides lessons for unresolved conflicts and has implications for areas of future dispute such as in the Gulf of Guinea, where Cameroon has initiated proceedings against Nigeria.     

Administrative gatekeeping - a third way between unrestricted patient advocacy and bedside rationing

The inevitable need for rationing of healthcare has apparently presented the medical profession with the dilemma of choosing the lesser of two evils. Physicians appear to be obliged to adopt either an implausible version of traditional professional ethics or an equally problematic ethics of bedside rationing. The former requires unrestricted advocacy of patients but prompts distrust, moral hazard and unfairness. The latter commits physicians to rationing at the bedside; but it is bound to introduce unfair inequalities among patients and lack of political accountability towards citizens. In this paper I shall argue that this dilemma is false, since a third intermediate alternative exists. This alternative, which I term 'administrative gatekeeping', makes it possible for physicians to be involved in rationing while at the same time being genuine advocates of their patients. According to this ideal, physicians are required to follow fair rules of rationing adopted at higher organizational levels within healthcare systems. At the same time, however, they are prohibited from including considerations of cost in their clinical decisions.     

Physically strong men are more militant: A test across four countries

There is substantial evidence from archaeology, anthropology, primatology, and psychology indicating that humans have a long evolutionary history of war. Natural selection, therefore, should have designed mental adaptations for making decisions about war. These adaptations evolved in past environments, and so they may respond to variables that were ancestrally relevant but not relevant in modern war. For example, ancestrally in small-scale combat, a skilled fighter would be more likely to survive a war and bring his side to victory. This ancestral regularity would have left its mark on modern men's intergroup psychology: more formidable men should still be more supportive of war. We test this hypothesis in four countries: Argentina, Denmark, Israel, and Romania. In three, physically strong men (but not strong women) were significantly more supportive of military action. These findings support the hypothesis that modern warfare is influenced by a psychology designed for ancestral war.     

校园再生水回用人工湿地景观绩效评价及优化设计——以辽宁公安司法管理干部学院为例

设计生态是相对于自然的生态而言的人工设计的生命与自然环境相互作用的系统,其是解决当代生态问题的新范式。从环境、社会、经济3个方面对辽宁公安司法管理干部学院人工湿地的设计生态的景观绩效进行了评价,主要得到以下结论:(1)人工湿地能对回用再生水产生一定的净化作用。再生水经过人工湿地后,TP、TN、NH_3-N、COD、SS分别减少74.9%、6.66%、61%、41.18%和64.71%,但整体水质类别保持不变。湿地基质土壤中TN、TP的含量与湿地水体有密切关系,再生水回用于人工湿地可以提高湿地基质中的土壤肥力。湿地周边植物生境类型为落叶阔叶林、灌木丛、草丛、浅水沼泽,其结构、优势种、下层植物差异明显。植物群落地域特征十分明显,整体多样性较为丰富,共计22科,37属,37种。(2)人工湿地景观为校园师生提供了较好的游憩、社交和视觉景观服务,超过80%的使用者对其总体评价在"满意"以上。同时,人工湿地运行、维护成本低,约每年可节约用水成本6.7万元。(3)以提供生态系统服务为目标的景观在设计初期,应当全面考虑运行中的地域独特性,提高设计绩效的预见度。     

Equitable maritime boundary delimitation,as exemplified in the work of the international court of justice during the presidency of sir Robert Yewdall Jennings and Beyond

The article contains a systematic survey of decisions rendered by the International Court of Justice (and its Chamber) under the presidency of Sir Robert Yewdall Jennings in three cases (Guinea Bissau v. Senegal, Gulf of Fonseca, and Denmark v. Norway,) involving equitable maritime delimitation, and in one case (East Timor) settled after Sir Robert's presidency. Distinct features, which are particularly pronounced in the landmark Denmark v. Norway Judgment, are the increased consistency and degree of predictability in the complex process of applying equity in maritime delimitation, of which Sir Robert has been a strong advocate. The important procedural aspects of the case law under Sir Robert's presidency are also analyzed. These are exemplified by the role of the Court as a partner in preventive diplomacy and by the precedential permission granted a third state to intervene as a nonparty. While highlighting the two presently pending cases (Qatar/Bahrain and Cameroon v. Nigeria), the author hopes that these settlements will significantly benefit from substantial and procedural solutions endorsed by the Court during Sir Robert's presidency.
