An overlook on statistical inference issues for stochastic damping hamiltonian systems under the fluctuation-dissipation condition

ABSTRACT

In this paper, we are interested in nonparametric inference issues for stochastic damping hamiltonian systems under the fluctuation-dissipation condition. This condition relates the magnitude of the dissipative term and the magnitude of the random term. The precise balance between the drift term which removes energy in average and the stochastic term provided by the fluctuation-dissipation relation insures that the canonical measure is preserved by the dynamics. In this framework, it is possible to give an explicit construction of a Lyapunov function and thus to prove exponential ergodicity. Then, we consider various estimation procedures and provide also a numerical section, where simulations are conducted.     

The Distribution of Returns to Education for People with Disabilities

This article takes a first look at the distribution of returns to education for people with disabilities, a particularly disadvantaged group whose labor market performances have not been well studied or documented. Using a nonparametric approach, we uncover significant heterogeneity in the returns to education for these workers, which is drastically masked by conventional parametric methods. Based on these estimates, we construct the Sharpe ratio of human capital investment (taking into account its substantial risk), and our results corroborate the claimed importance of human capital in improving these workers’ wages. Our stochastic dominance tests show that the returns to education for workers with disabilities, as a group, may have been affected more adversely in the most recent recession, relative to their non-disabled counterparts.     

Psychological Mediators of the Sport Injury—Perceived Risk Relationship

Drawing upon both heuristic‐ and threat‐based approaches, we sought to examine whether perceived similarity with injury‐prone people and perceived control over injury occurrence would directly contribute to perceived risk and whether these variables would mediate the previous injury–perceived risk relationship. Judokas (n = 207) reported the number of injuries experienced in the past year and then completed measures of perceived similarity, perceived control, and injury risk perception. Analyses revealed that perceived similarity and perceived control directly contributed to perceived risk of injury; only perceived similarity acted as a partial mediator of the injury–perceived risk relationship. These findings are discussed in relation to the potential influence of the sport context, which universally involves the acceptance of a high risk of injury.     

干部人事制度：新中国60年的演变与启示

干部人事制度包括干部管理机构、管理体制、管理程序等多方面内容,它是政治制度的重要组成部分,受制于社会政治经济文化等因素,又反过来影响着这些因素。新中国干部人事制度是在新民主主义革命时期干部工作的传统和经验的基础上建立和发展起来的,改革开放以后,进行了一系列改革,建立了公务员制度。法制化、科学化、民主化是干部人事制度发展的基本要求,公开、公平、竞争、择优是其发展的基本方向,服务于社会经济的发展和人民权益的实现是其基本价值取向。     

论行业语境下高校校友资源的开发与利用

校友资源是高校最富饶的人才资源。本文试图在行业语境中，讨论高校发展与校友资源之间的辩证关系，并以此为基础，提出开发和利用高校校友资源的对策。     

例论中越边境地区跨国婚姻子女的政治社会化

母亲是外国人,父亲是中国人,而且又位于偏远的边境和少数民族地区,所以这种跨国婚姻的子女在政治认同方面比一般小孩更加冷漠;在国家认同方面他们也为自己的母亲难以成为中国人而遗憾;在行为规范引导方面,他们地处走私、贩毒、拐卖妇女儿童等违法犯罪现象比较普遍的边境地区,在族群文化和国家主体文化及法律存在冲突的情况下,他们也面临着一些迷茫。边境跨国婚姻的子女也是祖国边疆的花朵,尤其需要呵护。在家庭方面,需要正视他们家庭不完整、家庭功能难以正常发挥的问题,需要帮助他们解决家庭的特殊困难;在社会方面,需要通过依法加强民主政治实践来强化他们对国家政治的认可;在学校教育方面,需要加强法制教育。     

伊拉克联邦制构建与境内库尔德人问题

萨达姆政权被推翻后,伊拉克新宪法草案所确立的国家联邦制结构,对国内库尔德人问题的解决乃至西亚地区库尔德人问题的走向无疑具有重要影响。本文认为,联邦制虽然能够满足少数民族的自治要求,但也容易刺激少数民族的分离欲望,而且少数民族与居人口多数的主体民族对联邦制的理解和要求存在差异,因而联邦制并非从根本上解决多民族国家民族矛盾和冲突的灵丹妙药;伊拉克的民族、教派冲突根深蒂固,国家构建任重道远,联邦制难以从根本上解决库尔德人问题。     

"阴阳合德":壮族传统文化的精华——《布洛陀经诗》的性别哲学研究之二

《布洛陀经诗》虽然已超越"孤雌繁殖"的认识阶段,但却没有完全陷入男性"惟我独尊"的窠臼。其中关于男女祖神并尊的唱颂,以及对妇女地位和作用的某种肯定,都在一定程度上体现了壮族性别哲学的精髓。这些思想是我们在寻求性别和谐发展之道时可以借鉴的。     

清代黔东南文斗苗族林业契约补论

针对此前学界认为在锦屏人工林业产权结构中 ,林地的所有制形式是“家族共有制”即“林地家族共同占有 ,而林地上经营的林木归家庭个体所有”的观点 ,笔者以充分的材料论证林业契约是林地“家庭私有制”的产物。文章还论述了文斗和锦屏林地主要在家族内部交易的原因。
