面向绿色制造的机床主轴加工工艺路线优化

针对机床主轴,提出面向绿色制造的工艺路线决策方法,旨在优化主轴制造工艺过程,减少能源消耗。通过对主轴各加工单元间的优先关系进行分析,建立加工工艺有向图,并对其进行分组拓扑排序和全拓扑排序,得出满足约束关系的所有可行路线,然后根据最优标准进行判断和评价,得出主轴加工的最优工艺路线。     

清代山东对琉球飘风难民的救助和抚恤

清代中琉封贡关系非常密切,除了官方的使节往来和朝贡贸易之外,双方的海难救助与抚恤也是重要内容。北至奉天,南至广东,都有琉球飘风难民所至,其中以福建、浙江为主。山东省虽然离琉球较远,但是对琉球飘风难民的救助和抚恤却不逊于其他省份。研究山东对琉球飘风难民的救助与抚恤,能够深化对我们对飘风难民问题的研究。同时,在中琉关系上,山东并非中心区域,对山东与琉球关系的考察能够帮助我们更加全面认识中琉关系。

Residential choices of immigrants in Australia

"In recent years Asian-Australians, especially those born in Indochina, have become a target of criticism by anti-immigration groups which accuse them of choosing to live only in ?closed societies' and ?ethnic ghettos' in Australian cities.... Evidence presented in the article shows clearly that while immigrant groups may prefer to settle in close proximity of their family and kin for practical and/or emotional reasons, their preference is not ethnically determined.... We also show that affordability, closeness to spouse's work, and neighbourhood services, rather than family and social contacts, are important factors for Asian-born immigrants when they move."

区域公共治理一体化中政治资源配置的理论借鉴与回应路径

政治资源配置对于区域公共治理一体化起着关键性的作用.当下,区域公共治理中政治资源配置面临着政府效用与公共效用、碎片化与共同利益、行政组织与行政区划、角色扮演与角色规定等诸多矛盾.资源依赖理论、网络理论、多中心理论对于区域政治资源优化配置提供了一定的理论借鉴.消解难点,优化区域政治资源配置的回应路径是:构建区域公共政策网络、完善多中心的区域公共治理机制、推进区域公共治理的制度安排.     

全球史观下的“澳门1601事件”

全球史观下的"澳门1601事件"反映出全球化早期不同文明相互影响的细节和模式。除了葡荷贸易竞争这个根本原因外,该事件亦掺杂了广东税吏与澳门葡人之间的利益冲突等诸多因素,而澳门因"双重效力"于两个贸易体系的特殊角色成为矛盾的焦点。该事件亦是葡荷两国、澳门与广东和明廷、广东地方与中央之间的诸多政治、宗教、财政、政策通过澳门相互作用的结果,从中可见澳门在世界贸易体系发展和变化过程中的特殊地位、历史作用及其具体机制。     

A Bayesian phase I/II design to determine subgroup-specific optimal dose for immunotherapy sequentially combined with radiotherapy

Sequential administration of immunotherapy following radiotherapy (immunoRT) has attracted much attention in cancer research. Due to its unique feature that radiotherapy upregulates the expression of a predictive biomarker for immunotherapy, novel clinical trial designs are needed for immunoRT to identify patient subgroups and the optimal dose for each subgroup. In this article, we propose a Bayesian phase I/II design for immunotherapy administered after standard-dose radiotherapy for this purpose. We construct a latent subgroup membership variable and model it as a function of the baseline and pre-post radiotherapy change in the predictive biomarker measurements. Conditional on the latent subgroup membership of each patient, we jointly model the continuous immune response and the binary efficacy outcome using plateau models, and model toxicity using the equivalent toxicity score approach to account for toxicity grades. During the trial, based on accumulating data, we continuously update model estimates and adaptively randomize patients to admissible doses. Simulation studies and an illustrative trial application show that our design has good operating characteristics in terms of identifying both patient subgroups and the optimal dose for each subgroup.     

汉唐土地、赋役制度与农民历史命运变迁--兼谈古代农民问题的研究视角

研究古代农民问题的传统视角是从地主和农民的阶级冲突层面分析农民破产、流亡的原因,对土地、赋役制度的缺陷注意不够.汉唐时代个体农民的普遍性是国家授田制的实施结果,无论是在授田,还是在占田、均田的名义之下,农民在本质上都是国家的课役农,都依附于国家;而以丁身定额征收田税、赋役的制度则加速了自耕农的破产,使农民由国家课役农转变为地主依附民,是赋役制度的缺陷使农民走上破产、流亡以至于揭竿起义之路的第一动因.两税法部分地舍人而税地,国家对农民人身控制弱化,也放弃了用行政手段调整土地占有状态的努力,农民与国家的关系、农民与地主的冲突进入到一个新的历史阶段.     

本体论的历史形态与当代视界

本体论伴随人类的生活实践经历了漫长的历史,其三种代表性存在方式却遭到现代人的质疑,以至于人们以为消解本体论十分必要。确认本体论的当代形态,改善了人们质疑本体论的现实状况。由于现代社会在物质繁荣的过程中产生了很多现实问题,又缺乏解决这类问题的有效手段,因此从本体论角度重审人类生活的本质规定是必要的。马克思对于本体论的态度对我们具有重要的启示意义,他"颠倒"了本体论的历史存在方式,他所勾勒的未来社会发展远景具有明显的本体论旨趣。当代哲学本体论开启了深远的意义视界,关注现代社会与现代人,融合理想指向与人类实践,明晰人文精神的"路标",使"爱智慧"的思维方式在"解释世界"和"改造世界"的过程中得到丰富和发展。
