产品服务供应链的“双重收益共享”合作机制

产品与服务融合缓解了"供需错位"矛盾，使得产品服务供应链探索成为"供给侧结构性改革"下供需结构性匹配的重要路径。本文刻画产品服务视角下供应链组织结构的本质特征，构建产品服务供应链合作模型，探讨合作机制下"帕累托改进"区间存在性，揭示合作机制对产品服务供应链效率的作用机理。核心研究发现：供应链多元化组织结构加剧收益分配冲突，并导致服务规模与供应链效率"倒挂"现象，而合作机制下"双重收益共享"合作模型能提升产品服务供应链效率。

Housing hardship and energy insecurity among native-born and immigrant low-income families with children in the United States

The costs for rent and utilities account for the largest share of living expenses, yet these two critical dimensions of material hardship have seldom been examined concurrently in population-based studies. This paper employs multivariate statistical analysis using American Community Survey data to demonstrate the relative risk ratio of low-income renter-occupied households with children experiencing ‘rent burden', ‘energy insecurity', or a ‘double burden’ as opposed to no burden. Findings suggest that low-income households are more likely to experience these economic hardships in general but that specific groups are disproportionately burdened in different ways. For instance, whereas immigrants are more likely to experience rental burden, they are less likely to experience energy insecurity and are also spared from the double burden. In contrast, native-born African Americans are more likely than all other groups to experience the double burden. These results may be driven by the housing stock available to certain groups due to racial residential segregation, decisions regarding the quality of housing low-income householders are able to afford, as well as home-country values, such as modest living and energy conservation practices, among immigrant families. This paper also points to important policy gaps in safety net benefits related to housing and energy targeting low-income households.     

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。     

写作表述的三级范式

写作表述在文句、层次和篇章等三个层级上都有一定的范式。表述范式在不同基本文体的层次范式之间、篇章范式之间,以及篇章范式和层次范式之间,虽然各有不同,但也有共同之处。这些表述范式分别都是其同类相仿的写作表述模式构造,能为写作者实施写作表述提供可以借鉴的基本经验。
