A note on the asymptotic distribution of the process capability index C pmk

Process capability indices have been widely used to evaluate the process performance to the continuous improvement of quality and productivity. The distribution of the estimator of the process capability index C _pmk is very complicated and the asymptotic distribution is proposed by Chen and Hsu [The asymptotic distribution of the processes capability index C _pmk , Comm. Statist. Theory Methods 24(5) (1995), pp. 1279–1291]. However, we found a critical error for the asymptotic distribution when the population mean is not equal to the midpoint of the specification limits. In this paper, a correct version of the asymptotic distribution is given. An asymptotic confidence interval of C _pmk by using the correct version of asymptotic distribution is proposed and the lower bound can be used to test if the process is capable. A simulation study of the coverage probability of the proposed confidence interval is shown to be satisfactory. The relation of six sigma technique and the index C _pmk is also discussed in this paper. An asymptotic testing procedure to determine if a process is capable based on the index of C _pmk is also given in this paper.     

任务分解式教学法在检测技术实训中的应用

如何提高实践教学的教学质量是高校教育中亟待解决的问题。以安全检测技术实训为例,采用任务分解式教学方法对这一问题进行了探讨,在实训过程中,通过不断增加具体任务难度、分组打擂、优秀组讲解程序等方式,将安全检测技术各个部分内容有机结合起来,从而为实践教学环节提供一些有益的思路。     

习近平关于人民健康重要论述的思想内涵与实践价值研究

人民健康是人民福祉之本、强国建设之基。习近平关于人民健康重要论述基于“健康中国”战略和全面建成小康社会的 时代背景下，针对突发公共卫生事件应急管理能力滞后以及传染病等问题，系统阐述了习近平把人民群众生命安全和身体健 康放在第一位；以人民为中心，以健康为根本的思想；大卫生、大健康新理念；人民健康是最大的生产力；人民健康是全面的健 康以及习近平关于新冠肺炎防控的思想内涵。通过研究习近平关于人民健康重要论述的实践价值，有利于推进国家治理体系 和治理能力现代化，更好地应对国内出现的重大疫情，实现“健康中国2030”战略，维护国家安宁与国际稳定，更好地体现中国 防疫经验的世界意义。     

应用型高校与企业共建产业学院的优势与困惑

产业学院是应用型高校为服务地方社会经济的发展而与企业深度合作形成的新型办学机构，由高校和企业共同投资，实行理事会领导、院长负责的管理体制，校企协同育人，重视实践教学，组织特征鲜明，办学优势突出。但是，产业学院在发展过程中面临诸多不足：独立法人地位尚未确立，进一步发展缺乏法律保障和依据；现代治理方式和结构尚未建立，具体工作受高校干扰较多，行政化色彩浓厚；运行成本大，缺乏市场化运行机制。为了促进产业学院发展，国家应确立其独立的法律地位，营造发展的政策环境和建立现代化的治理方式与结构；产业学院应建立市场化运行机制，激发面对市场的应变能力，最大限度地发挥自身优势，化解发展过程中的短板。     

“GPS测量与数据处理”课程教学与改革

卫星导航定位是测绘工程中发展较快、应用较广的一项热门技术,“GPS测量与数据处理”课程也一直是测绘专业本科教学的主干课程,具有更新快、理论深、实践性强等特点,对教师授课及学生学习都具有较高的要求。文章对东华理工大学测绘工程专业GPS课程的授课内容、授课方式、实践教学及考核模式等方面存在的问题进行了分析,并提出了相应的教学改革建议。     

当代中国马克思主义大众化的理论创新与实践创新

任何理论的演化都无法脱离其所属的时代。马克思主义大众化的演化历程反映了马克思主义基本原理不断融入中国革命和改革开放实践的过程,马克思主义在中国的演化过程与中国的时代背景密切相关。马克思主义大众化是理论创新和实践创新不断结合的过程,包含着对理论与实践关系的理解,是指在国内外形势之下马克思主义由理论到实践、由书斋到世俗、由被少数人推崇到被人民群众所接受的历程。创新是马克思主义大众化和现代化建设实践相统一的基本途径,彰显了马克思主义演化过程中理论创新和实践创新的不断融合。在当代中国,从理论与实践的层面上分析马克思主义大众化何以可能的问题,对指导当代中国马克思主义创新有一定意义。

Repetitive variable acceptance sampling plan for one-sided specification

In this paper, a variable repetitive group sampling plans based on one-sided process capability indices is proposed to deal with lot sentencing for one-sided specifications. The parameters of the proposed plans are tabulated for some combinations of acceptance quality levels with commonly used producer's risk and consumer's risk. The efficiency of the proposed plan is compared with the Pearn and Wu [Critical acceptance values and sample sizes of a variables sampling plan for very low fraction of defectives. Omega – Int J Manag Sci. 2006;34(1):90–101] plan in terms of sample size and the power curve. One example is given to illustrate the proposed methodology.     

高技能人才职业素养形成规律及其养成

文章分析了职业素养的内涵及在职业生涯中的主导作用,分析了装备制造业高技能人才职业素养的形成规律,指出实践教学在形成高职工科学生的职业习惯、职业意识和职业道德中具有不可替代的作用。把职业素养培养和专业教学相结合,充分利用实践教学资源,特别是顶岗实习环节,是提升学生职业素养的基本途径。在专业性的实践教学中,教师要发挥表率引导作用、课程设置要体现专业性、教学组织要体现职业性,在顶岗实习中要加强协调,保证实习效果。     

Shared service center research: A review of the past,present, and future

More than 75% of Fortune 500 companies have established models of shared services with the aim of gaining superior performance by cost savings and service enhancements. Despite scholars' complaints about scant shared service center (SSC) research, this study shows that the actual shortcoming in this stream concerns a high fragmentation of the academic literature (e.g., we found 137 works in the initial search and 83 works in a refined screen). In this first comprehensive literature review, we synthesize peer-reviewed articles and classify them into 4 perspectives according to their research questions (i.e., determinant, process, control, and outcome). We identify 17 major research areas across these perspectives. Additionally, we provide information on methodologies and theories. On the basis of the literature synthesis, we discuss opportunities and gaps and propose an agenda for future research. Specifically, we suggest 3 potential research directions (i.e., direct relationships, mediating, and outcome effects) regarding SSCs during their operational maturity phase.
