Lower bound of average centered L2-discrepancy for U-type designs

Uniform designs are widely used in various scientific investigations and industrial applications. By considering all possible level permutation of the factors, a connection between average centered L₂-discrepancy and generalized wordlength pattern for asymmetrical fractional factorial designs is derived. Moreover, we present new lower bounds to the average centered L₂-discrepancy for symmetrical and asymmetrical U-type designs. For illustration of the theoretical results, the lower bounds for symmetrical and asymmetrical U-type designs are tabulated, and numerical results indicate that our lower bounds behave well and can be recommended for use in practice.     

Impact of mindful self-care and perceived stress on the health related quality of life among young-adult students in West Virginia

ABSTRACT

There are substantial gaps in research on Health Related Quality of Life (HRQoL) in students aged 18 and above in West Virginia. The purpose of this study is to explore the associations between mindful self-care, perceived stress, and the HRQoL in this population. We conducted a cross-sectional study between March and April 2017. We included participants who were students, aged 18 years and above, living in West Virginia and were able to answer online questions in English. Data was obtained from an online survey using a structured questionnaire, including the SF12v2®, mindful self-care scale- SHORT, and Perceived Stress Scale (PSS)-10. We applied linear regressions to determine the predictors of HRQoL (physical health and mental health) using SF12v2®. 194 participants met the inclusion criteria of the study. Mindful self-care was negatively associated with perceived stress. Better mindful self-care mediated the relationship between perceived stress and psychological well-being, controlling for gender, age, race, marital status, education level, annual household income, and chronic disease status. Perceived stress and mindful self-care were not related to the physical well-being. Better mindful self-care may safeguard against perceived stress among students aged 18 years and above. Our findings in this study recommend more mindfulness-based interventions targeted to this subpopulation to improve psychological well-being.     

语料库在医学英语词汇教学中的应用

让语料库说话已经成为了语言学界的一个共识,真实的语料结合理性的分析不仅是语言研究也是英语词汇学习的重要 途径。语料库在医学英语词汇教学中有着巨大的潜力,通过语料库检索软件,引导学生对真实自然的语料进行按部就班的分 析、模仿、学习、应用,可以在很大程度上提升医学英语的词汇学习效率。     

将审计风险理论引入内部审计实践

审计风险 ,是指会计报表存在重大错报或漏报 ,而注册会计师审计后发表不恰当审计意见的可能性。在审计界审计风险日益得到认识和重视 ,内部审计人员有责任探究审计风险理论 ,充分认识审计风险的概念、特征及其产生的原因 ,探索审计风险的防范措施 ,并将其运用到内部审计实践当中 ,建立控制审计风险体系 ,从而达到规避审计风险 ,提高审计工作质量 ,巩固内审部门地位的目的     

绿色贸易壁垒与我国纺织品出口对策

在纺织品服装领域存在四种绿色贸易壁垒——国际环境管理体系系列标准、生态纺织品认证标准、绿色标志制度、绿色法规，对我国入世后纺织品、服装出口具有重要影响，我国政府和企业应采取的对策是提高环保意识、发展企业的绿色生产、加强环保法规和标准建设、加强绿色纺织品的科研与开展等。     

基本养老保险实现全国统筹的理论支撑与实践操作

基本养老保险全国统筹涉及多视角理论依据,其主要支撑理论包括大数法则原理、社会公平理论、收入再分配理论和博弈理论,其现实依据在于目前我国基本养老保险统筹层次过低导致的突出问题和提高统筹层次面临的障碍。顺利实现基本养老保险全国统筹,应不断完善基本养老保险制度和相关配套设施的建设。     

我国刑法典的轻罪化改造

由立法定性加立法定量的犯罪设定模式所决定,我国现行刑法典呈现出明显的重罪重刑的特点。这使得刑法典原本设定的限缩式的犯罪圈出现不断任意扩张的趋势,同时又陷入在重刑基础上再加大刑罚投入量的恶性循环。在不彻底动摇我国刑法典中立法定性加立法定量的犯罪设定模式的前提下,就消减"重罪重刑"式的刑法典存在的上述弊端而言,需要对刑法典进行轻罪化改造。具体而言,一方面应对现行刑法典划定的犯罪圈进行轻罪化改造,即适度扩张犯罪圈,将更多的轻罪纳入刑法处罚的范围;另一方面,应摒弃传统的重刑主义观念,对现行刑法典中的法定刑作轻刑化改造,即从总体上对已有的法定刑刑种作轻刑化调整,并为部分犯罪增加轻刑的法定刑档次,从而使轻刑的适用具有法律上的根据,为这些犯罪增加轻罪的情形。

基于经济全球化视角的中国民族企业跨文化营销战略研究

经济全球化必然伴随着国际区域经济的一体化,跨文化营销实践在这一进程中得到不断深化,并成为影响现代国际市场竞争格局的重要因素。以美国、日本等为代表的现代市场经济体,在不同文化背景下的各个海外目标市场经营取得了成功。这为我国企业开拓海外市场提供了很多有益的启示。     

论我国宪法的司法适用性

宪法具有司法适用性,已成为当代宪法发展的重要趋势之一.但是,在我国,由于认识上的偏差、理论研究的缺失以及不适当的司法解释,学术界和司法界普遍认为我国宪法不具有司法适用性.本文认为,作为对当代宪法发展趋势的积极回应,我国宪法应当具有司法适用性,并且我国宪法司法适用性具有法律的、实践的充分依据.
