论维柯《新科学》的美学意义

维柯《新科学》在西方思想史上占据着特殊地位,它为多个学科开辟了道路。就美学较适宜的界定"感性学"而言,《新科学》的美学意义体现于五个方面:第一,辟开"诗性文化"世界;第二,在包括感性在内的人性研究上,得出不少重要的发现或假说;第三,在诗学上,特别是在语言的发生研究与史诗的个案研究领域实现了突破;第四,艺术哲学上,揭示出艺术的社会功能和艺术发展史中的人类需求规律;第五,审美学上,维柯停留于古希腊哲学或经院哲学的美之观念层面。     

Delicious molecules: big food science,the chemosenses,and umami

Abstract

Since the closing decades of the twentieth century, molecular techniques of mapping chemosensation (the chemical senses of taste and smell) have been woven into a universalizing, evolutionary explanation for human eating behavior. In a prominent example, umami (translated from Japanese as “savory deliciousness”) has come to be understood as the “fifth basic taste sensation,” elicited by the common flavor enhancer monosodium glutamate (MSG) along with other amino acids and ribonucleotides. Meanwhile, socialized associations of food desirability, undesirability, pleasure, and disgust have likewise come to be interrogated on the molecular level – in the oral cavity, in the brain, and throughout the gastrointestinal tract. In this paper, I abridge this molecularization of sensuous eating with the provocation that the sensory is affective is molecular is political. This phrase signals the stakes with which taste and smell are ontologized as fundamentally embedded in memory (and thus in affect and in culture); as conducted in train with corporate food and beverage research and development; and effected at molecular sites of transduction (chemical reception). It is to say that, in recent decades, the sensory and affective domains have been made molecular. And in the context of food science, that molecular knowledge is interested. This paper conducts a brief, critical accounting of how chemosensation is made knowable and actionable, and for what purposes. It suggests that the most authoritative knowledge of how taste and smell mediate human health (the sensory) is shaped by the corporate imperative to determine what chemical compounds humans register as pleasurable (the affective), and thus what food products humans can be relied upon to buy (the political). As a result, a lack of scientific consensus on wider questions of metabolism – of glutamate, for instance – is built into chemosensory science, which has privileged the work of product design.     

Analytical expression for the integrated squared density partial derivative of a multivariate normal mixture distribution

This paper describes the derivation of the analytical expression for the integrated squared density partial derivative (ISDPD) in a multivariate normal mixture model. The analytical expression of the ISDPD is derived for arbitrary dimensions with partial derivative orders up to four. Although the value of the ISDPD can be obtained by using the common numerical integration via mathematical software (such as Maple, Mathematica, Matlab, etc), it suffers from the limitation of computation time when the dimension or the number of mixture components of the considered multivariate normal mixture model are large. Moreover, numerical comparison indicates the benefits of speed offered by our proposed analytical expression are far superior to the numerical integration performed by Maple. With this analytical expression, the ISDPD can apace be calculated with no assistance of numerical integration.     

科研评价体系中学术论文评价实证分析

针对当前科研评价体系中中对学术论文质量的评价存在局限性的问题,以计算机学科中的学术论文评价为实证,以某大学的科研评价标准体系与考核指标为案例,地学术论文评价的相关问题进行研究。研究认为,如何定位会议论文和SCI期刊论文在科研评价体系中的价值与定位,能否坚持正确导向是科研管理评价体系面临的主要问题;在计算机学科中,国际上大部分的标志性成果都会在顶级会议上发表论文,但中国的科研评价体系仍以SCI期刊论文为主,中国学者在国际计算机学会的权威会议上参与与发文量均较低;中国的科研评价体系中应重视顶级会议论文的重要性,平衡不同评价指标的权重,平衡不同学科领域之间的差异,提高会议论文认定的等级,发挥评价体系的导向作用,制定科学的评价指标,完善科研评价管理制度;某高校制定了分学科科研评价标准体系和差异化的考核指标,依据不同的专业领域拟定了同行专家评价认可的期刊与会议列表,规范了期刊文章和会议文章的量化指标来综合衡量学术论文的学术和文献价值,在学术科研的国际化方面取得了显著成绩。     

论我国民间信仰的多元一体化格局

我国民间信仰存在多元一体化之格局。所谓＂多元＂,是各地民间信仰表现的极端多样化;所谓＂一体＂,是全民族大体一致的以＂天地君亲师＂为至尊的信仰秩列。民间信仰多元一体化格局的形成具有多方面的原因;形成之路径,主要有民族迁徙与神道设教、感恩祈福等方面。民间信仰以社神和祖先崇拜为根基,＂天地君亲师＂五位亦以地（社）、亲（祖先）为核心,故中国民间信仰宜称为＂社祖教＂。
