Krabbe disease or globoid cell leukodystrophy(GLD;MIM#245200)is a rare and fatal lysosomal storage disease with an autosomal recessive mode of inheritance that results from the deficiency of galactocerebrosidase(GALC;E.C.3.***.1.46),a lysosomal enzyme encoded by the GALC gene.1 GALC breaks down galactosylceramide,a cerebroside located mainly in the myelin *** in GALC cause the accumulation of a cytotoxic metabolite,galactosylsphingosine or psychosine,which can be toxic to oligodendrocytes and Schwann cells.2 The failure to digest galactosylceramide triggers the formation of multi-nucleated globoid cells,causing severe demyelination,axonopathy,and neuronal death.3 The reported frequency of Krabbe disease is 1 in 100,000 live births with symptoms including irritability,loss of motor ability,spasticity,ataxia,visual dysfunction,seizures,andcognitive impairment.

民族文化对人们的生活和经营方式有非常主要的影响。民族文化决定了组织文化和经营方式。Hofstede从五个方面分析了各国的文化:权力距离,对不确定因素的避免,个人主义/集体主义,男性化/女性化,以及长期/短期取向。有许多新旧理论解释领导风格。Avolio和Bass(2004)’s理论是最新的理论之一,它提供了三种领导风格,即变革型领导、交易型领导风格和被动领导风格。在国家层面上,有许多研究探讨民族文化与领导风格的关系。本研究探讨了民族文化对国际项目管理领导风格的影响。一个国际属于"一带一路"倡议的项目作为案例研究。利用CVSCALE和MLQ-5X调查表设计了调查表。CVSCALE是一个调查问卷,以衡量Hofstede的国家文化维度包括26个问题。MLQ-5X是由Avolio和Bass开发的领导调查表,包括36个问题。为了解在该项目中工作的中国员工的情况,本问卷翻译成中文。为检验假设,向项目中的低级、中级和高级管理人员、工程师和非管理人员分发了200份调查问卷,其中70份填写和归还。进行了相关性检验,检验了第一个假设,即民族文化与领导风格的关系。进行了相关性和回归分析为了检验第二种假设。所有检验都是使用统计软件SPSS 21版进行的。结果表明,各文化维度之间的相关性是正的。此外,所有民族文化方面都与不同的领导风格既有正相关和负相关,除了个人主义(IDV)于变革型领导风格(TFLS),以及男性主义(MSI)和个人主义(IDV)于交易领导风格。功率距离(PDI)与交易领导风格呈负相关。本研究是对国际项目管理中领导风格的理解的补充,将有助于人员为特定的国际背景选择合适的领导风格。

Here thermal dependence conductivity and nonlinear convection features in third-grade liquid flow bounded by moving surface having varying thickness are formulated. Stagnation point flow is considered. Revised FourierFick relations and double stratification phenomena are utilized for modeling energy and concentration *** model of considered physical problem is achieved by implementing the idea of boundary layer theory. The acquired partial differential system is transformed into ordinary ones by employing relevant variables. The homotopic scheme yield convergent solutions of governing nonlinear expressions. Graphs are constructed for distinct values of physical constraints to elaborate the heat/mass transportation mechanisms.
