More on the ontological status of autism and double empathy

This response to Milton’s recent article on the ontological status of autism and double empathy also explores, through the lens of ‘double empathy’ and ‘theory of mind’, the issues of relationality and interaction that researchers in the fields of cognitive neuroscience and psychology hardly acknowledge. I go on to consider Wittgenstein’s criteriological view of mind, propose a synthesis of theory to describe autism, and suggest that public criteria of a non-autistic ontology enable many autistic people to eventually develop the understanding of other (non-autistic) minds that, in turn, enables them to survive, and even thrive.     

“科学技术是双刃剑”质疑

在学术界,持"科学技术是双刃剑"论的学者,似乎没有真正搞清楚科学技术的基本性质,因而他们的观点存在诸多明显缺陷。科学技术具有真、善、美的本性。具有真、善、美本性的科学技术,不可能同时包含着假、恶、丑的内容,因而"科学技术是双刃剑"的命题不合逻辑。人类在利用科学技术从事实践活动的过程中,常常会受到来自自然界盲目力量的报复,那是因为人类的无知。而一些个人、团体和国家利用科学技术从事犯罪活动,则根源于他们的贪婪,没有理由把他们犯下的罪行归咎于科学技术。     

On characterizing the normal and poisson distributions

Multivariate normal, correlated multivariate Poisson and multiple Poisson distributions are characterized, in the class of exponential-type distributions, by the properties of the linear combinations of the variables, the properties of their cumulants and the recurance relation between the cumulants.     

关于高校管理中“双肩挑”问题的探讨

为了做好专业技术岗位聘用工作,高校应该认真研究普遍存在的“双肩挑”人员的管理现状和探索新的使用方法。笔者对高校中“双肩挑”管理模式现行管理政策与措施进行了调查和研究,提出了应加强对“双肩挑”岗位设置的管理,同时,应注重管理队伍朝着专职和专业的方向发展,并在高校中逐步提高学术权力的领导地位、建立新时期高校管理体制的新格局和确保高校人事管理科学发展的建议。     

Repurposing Materials and Waste through Online Exchanges: Overcoming the Last Hurdle

Online material and waste exchanges (OMWEs) provide online channels to repurpose by‐products, unused materials and waste from industrial and commercial facilities. Unfortunately, OMWE's also have challenges. First, sellers may have access to other disposal options and, as a result, may not fully commit to the exchange. Second, buyers can face high uncertainty about the product exchanged and the transaction being undertaken. Overcoming these challenges is the “last hurdle” to making OMWEs successful. This study investigates the factors that reduce the buyers' uncertainty and increase the sellers' commitment to the OMWE. We analyze novel transaction‐level data from an online exchange (MNExchange.org) combined with other archival public records on county‐level repurposing and disposal statistics. First, we find that regional repurposing policies and alternatives have a complementary effect on sellers' commitment toward OMWEs, resulting in increased OMWE exchanges. However, regional disposal policies and alternatives have a substitution effect on sellers' commitment, resulting in reduced exchange success. Further, greater product and transaction information reduce the buyer's uncertainty and increase exchange success. Finally, the analysis shows that users' (buyers and sellers) heavily rely on their prior experience with OMWEs. Specifically, higher familiarity between the buyer–seller pair and familiarity with the OMWE system leads to higher likelihood of exchange success. This study lays the foundation for understanding OMWEs and has important implications for developing policies and operations to increase online transactions of by‐products, materials and wastes.     

中国粮食价格形成机制逆市场化的逻辑:观念的局限与体制的制约

近十年来,中国粮食价格形成机制日益逆市场化,并最终固化为以政府定价为核心.这种逆市场化的价格形成机制,在短期内增强粮食产能和助力农民增收的同时,也在中长期内导致中国粮食生产、流通、进口、库存、加工、消费的全面扭曲.文章着重从观念和体制角度,探讨了中国粮食价格形成机制逆市场化的内在逻辑:观念的局限主要在于不信任市场,对粮食供求形势过分紧张,过度强调粮食总产量,而静态化思维、历史记忆、惯性判断及前期经验又强化了以上观念;体制的制约主要在于独大且难以监控的单一政府储备主体与叠床架屋的涉粮行政管理体制.中国粮食价格形成机制逆市场化,源于落伍的观念与体制的制约之间的相互强化,因而,中国粮食价格形成机制改革,必须同时转变观念与加快体制调整.     

A Rejection Principle for Sequential Tests of Multiple Hypotheses Controlling Familywise Error Rates

We present a unifying approach to multiple testing procedures for sequential (or streaming) data by giving sufficient conditions for a sequential multiple testing procedure to control the familywise error rate (FWER). Together, we call these conditions a ‘rejection principle for sequential tests’, which we then apply to some existing sequential multiple testing procedures to give simplified understanding of their FWER control. Next, the principle is applied to derive two new sequential multiple testing procedures with provable FWER control, one for testing hypotheses in order and another for closed testing. Examples of these new procedures are given by applying them to a chromosome aberration data set and finding the maximum safe dose of a treatment.     

Combining Inverse Probability Weighting and Multiple Imputation to Improve Robustness of Estimation

Inverse probability weighting (IPW) and multiple imputation are two widely adopted approaches dealing with missing data. The former models the selection probability, and the latter models data distribution. Consistent estimation requires correct specification of corresponding models. Although the augmented IPW method provides an extra layer of protection on consistency, it is usually not sufficient in practice as the true data‐generating process is unknown. This paper proposes a method combining the two approaches in the same spirit of calibration in sampling survey literature. Multiple models for both the selection probability and data distribution can be simultaneously accounted for, and the resulting estimator is consistent if any model is correctly specified. The proposed method is within the framework of estimating equations and is general enough to cover regression analysis with missing outcomes and/or missing covariates. Results on both theoretical and numerical investigation are provided.     

金沙古史探微

在成都摸底河两岸发现的金沙遗址是历史上开明王朝生活于此的文化遗存.开明族富于治水经验,他们进入成都平原后很快就取代了出自西山的古蜀族,建立了金沙古城,因此这里并无望帝于丛帝禅让的情况.而古蜀族地位逐渐下降,其沦为二等公民殆无疑义.金沙古城与十二桥遗址相近,应是同时代的双子城.金沙时代气候温暖潮湿,其自然环境与三星堆时代迥然不同.距今约2300年前,金沙古城毁于洪水,不久强秦入侵,开明族统治结束,亦即古蜀最后覆亡.     

以目的与背景知识为双条件的逻辑AKC

首先,我们构造以目的和背景知识为双条件的条件句系统AKC,给出它的一些证明论结果。其次,我们引入有序邻域语义,给出描述AKC的特征公理和推理规则的框架条件,证明AKC相对这些框架条件是框架可靠的。最后,我们证明AKC相对这些框架条件也是框架完全的。
