To observe the clinical changes of meibomian gland dysfunctipn(MGD)and ocular Demodex infestation after intense pulsed light(IPL)treatment to further examine the mechanism of IPL treating patients with MGD and ocular Demodex *** medical records of 25 patients(49 eyes)with MGD treated with IPL,were retrospectively examined to determine *** ocular-surface parameters(ocular surface disease index,OSD1;lipid layer thickness,LLT;noninvasive first breakup time,NIF-BUT;noninvasive average breakup time,NIAvg?BUT;tear film breakup area,TBUA;Schirmer I Test,SIT;corneal fluorescein staining,CFS),eyelid margin abnormalities,meibum quality and expressibility,MG morphological parameters(macrostructure and microstructure),and the number of Demodex infestation were examined before and after *** MG microstructure and the Demodex infestation were examined via in vivo confocal microscopy(IVCM).The results showed that there were statistically significant differences in associated ocular-surface parameters(all P<0.05)before and after IPL treatment,except SIT(P=0.065).Eyelid margin abnormalities,meibum quality and expressibility obviously improved in upper and lower eyelid after IPL treatment(all P<0.0001).MG macrostructure(MG dropouts)decreased in upper(P=0.002)and lower eyelid(P=0.001)after IPL *** nine parameters of MG microstructure in upper and lower eyelid all distinctly improved after IPL treatment(all P<0.0001).The mean number of Demodex mites on the upper lid margin(6.59±7.16 to 3.12±3.81/9 eyelashes)and lower lid margin(2.55±2.11 to 1.29±1.53/9 eyelashes)significantly reduced after IPL treatment(all P<0.0001).The Demodex eradication rate was 20%(8/40)in upper lid margin and 34.15%(14/41)in lower lid *** findings indicate that IPL shows great therapeutic potential for patients of MGD and ocular Demodex infestation.

A theoretical model for enzyme entrapped conducting polymer modified electrodes is proposed and appropriate expressions are derived for the steady state current response of the enzyme electrode. More attention has been paid to the role of conducting polymer in electron transfer and the effect of mass transport. On the basis of kinetic analysis, the performance and optimum design of the second and third generation enzyme electrodes are discussed.

数智机器批判中的“马克思之手”

区别于工业时代蒸汽机般的热动力学机器的数智机器,已成为社会世界中一个重要组成部分。它改造了常人与自然世界的关系,在构造的社会世界中结成常人与数智机器的关系:常人建造数智机器,数智机器越来越像常人,并逆向影响常人,在这个社会世界中,数智机器令常人变成非常人,甚至变成常人与非常人的关系。借用“马克思之手”作为理论分析工具,可以对马克思的机器批判理论作出回顾,以作为“马克思之手”的劳动为现实底座,分析常人和机器的关系,以及常人变为非常人的原因,从而进一步增进我们理解数智机器批判的现实前提。非常人般的数智机器向常人般的数智机器发展的潜在要求,已经成为学术研究的新动向,常人般的计算实践则进一步说明了“马克思之手”对数智机器批判的现实意义。

马克思劳动概念的本体论和演化论路径分析

西南民族大学学报（人文社会科学版） 2020年第2期41卷 94-99页

作者：黄侃贵州大学哲学与社会发展学院

马克思的劳动概念是赋予人现实地位的重要概念。在哲学上它是唯物论解释人类社会历史发展的重要支点。它既有对超验的人做出批评的理论功能,还有对资本主义异化劳动进行揭示的现实功能。从劳动概念的现实主义立场出发进行分析,劳动赋予... 详细信息

马克思的劳动概念是赋予人现实地位的重要概念。在哲学上它是唯物论解释人类社会历史发展的重要支点。它既有对超验的人做出批评的理论功能,还有对资本主义异化劳动进行揭示的现实功能。从劳动概念的现实主义立场出发进行分析,劳动赋予人以动态的本体论地位,这一点无疑是支点作用的重要体现。另外,马克思从"对象性"和"感性"入手实现了与传统哲学对人做出抽象性解释相告别。然而,"对象性"和"感性"从演化心理学的角度指向了人的生理性和心理性,实际上异化的多面表现是生理性和心理性不适应所造成。

具身认知和延展认知为认知科学的"实践转向"做了重要贡献。但是在"实践"的名义下两者并没有走向同一条道路。借助科学实践哲学的研究成果来评估认知科学研究的实践进路,一方面有助于从科学哲学关于理论和实践的传统中找到"实践转向"的哲学基础;另一方面有助于从科学实践哲学的三重特征的分析中找到"实践转向"的哲学根据。从而表明,具身认知可以在实践传统中找到现象学的路子,延展认知可以在实践传统中找到实用主义的路子,这两条路子都够得上说是"实践的"。

数码技术和智能技术汇聚成数智技术,正颠覆性地介入人类社会生活和生产,加速建构数码人格。数码人格不属于自然哲学的研究范畴,也不是存在于自然世界中的研究对象,而是人工世界的产物;数码人格作为人类的另一面镜子,它是什么,从哪里来,我们如何认识它等问题正成为哲学研究的新任务。研究人格与数码人格的建构和两者的区别,有助于理解异化的数码人格在应用上的能力缺陷,数码人格成为个人的负担,加剧人的无产阶级化。个人与数码人格之间的错置是信息拜物教向数码拜物教升级的结果,为了摆脱或规避数码拜物教带来的不适,需要从新人文主义的立场来疏解数智技术遗留的哲学难题。
