摩天时代背景下当代城市建设的反思

摩天大楼成为近年来中国城市建设的重要特征。摩天大楼时代到来的同时，也带来了高楼建筑的社会问题，如安全问题、能原消耗问题、投资风险等。欧洲城市在建造高楼方面，保持了克制与理智的态度，欧洲国家纷纷制定各种法令限制摩天大楼的建设。作为河北省省会城市，2008年开始的“三年大变样”，使石家庄的城市建设步入摩天时代。2012年，石家庄市城乡规划局出台了《石家庄市城市风貌特色管理暂行规定》，石家庄将加强城市风貌特色管理，提高城市品位。人与高楼的和谐共融才是城市建筑存在的重要意义，如此，高楼大厦才会有灵魂，城市才会有未     

高新企业并购中的人力资源整合管理

在产业升级、结构调整以及经济一体化等因素的推动下,我国高新技术企业的并购规模和数量一直呈现不断上升趋势,并购的地域范围不再限于国内,全球范围的并购案例也迅速增长。越来越多的高新技术企业寻求通过并购方式来提高企业核心竞争能力,谋求企业的可持续发展。然而,并非所有的并购都能成功。     

Modified chain sampling plans for lot inspection by variables and attributes

The purpose of acceptance sampling is to develop decision rules to accept or reject production lots based on sample data. When testing is destructive or expensive, dependent sampling procedures cumulate results from several preceding lots. This chaining of past lot results reduces the required size of the samples. A large part of these procedures only chain past lot results when defects are found in the current sample. However, such selective use of past lot results only achieves a limited reduction of sample sizes. In this article, a modified approach for chaining past lot results is proposed that is less selective in its use of quality history and, as a result, requires a smaller sample size than the one required for commonly used dependent sampling procedures, such as multiple dependent sampling plans and chain sampling plans of Dodge. The proposed plans are applicable for inspection by attributes and inspection by variables. Several properties of their operating characteristic-curves are derived, and search procedures are given to select such modified chain sampling plans by using the two-point method.     

日本新订高中历史课程之特点与启示

2018年3月,日本发布新的《高等学校学习指导要领》。这是日本自第二次世界大战后70多年来,对高中课程最大规模的一次修订,体现了日本高中教育发展的新趋势,标志着日本从此告别“宽松教育”而走向“生存能力”教育。由“历史综合”“日本史探究”“世界史探究”组成的新高中历史课程,立足“人”的发展,构建了“必修+选修、通史+专题”的课程体系,课程内容更加突出本国史与世界史的联系,课程学习倡导“主题+探究”的学习方式。日本高中历史课程的内容设置及特点启示我们,高中历史课程编制应加强中国史与世界史的横向关联,课程内容应体现探究性学习要求。     

Transition probabilities and ARL performance of Six Sigma zone control charts

In this article, Six Sigma zone control charts (SSZCCs) are proposed for world class organizations. The transition probabilities are obtained using the Markov chain approach. The Average Run Length (ARL) values are then presented. The ARL performance of the proposed SSZCCs and the standard Six Sigma control chart (SSCC) without zones or run rules is studied. The ARL performance of these charts is then compared with those of the other standard zone control charts (ZCCs), the modified ZCC and the traditional Shewhart control chart (SCC) with common run rules. As expected, it is shown that the proposed SSZCC outperforms the standard SSCC without zones or run rules for process shifts of any magnitude. When compared to the other standard ZCCs and the Shewhart chart with common run rules, it is observed that the proposed SSZCCs have much higher false alarm rates for smaller shifts and hence they prevent unwanted process disturbances. The application of the proposed SSZCC is illustrated using a real time example.

Identifying Latent Structures in Panel Data

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized techniques. We consider both linear and nonlinear models where the regression coefficients are heterogeneous across groups but homogeneous within a group and the group membership is unknown. Two approaches are considered—penalized profile likelihood (PPL) estimation for the general nonlinear models without endogenous regressors, and penalized GMM (PGMM) estimation for linear models with endogeneity. In both cases, we develop a new variant of Lasso called classifier‐Lasso (C‐Lasso) that serves to shrink individual coefficients to the unknown group‐specific coefficients. C‐Lasso achieves simultaneous classification and consistent estimation in a single step and the classification exhibits the desirable property of uniform consistency. For PPL estimation, C‐Lasso also achieves the oracle property so that group‐specific parameter estimators are asymptotically equivalent to infeasible estimators that use individual group identity information. For PGMM estimation, the oracle property of C‐Lasso is preserved in some special cases. Simulations demonstrate good finite‐sample performance of the approach in both classification and estimation. Empirical applications to both linear and nonlinear models are presented.     

陕西地方院校高层次人才引进策略研究?

陕西地方院校长期存在着学校知名度不高,教师收入水平低,高层次人才储备不足、引进困难和增长缓慢的不良现状。为改善这一现状,有效加强高层次人才引进工作力度,陕西地方院校应以重点学科为突破点,以实际需求为导向,牢固树立成本意识,理性制定高层次人才引进策略;应增强引才主动意识,积极学习西方发达国家引才理念,善于利用政府牵引模式下的高层次人才引进合力,全面活化高层次人才引进手段;应注重经济契约与心理契约有机结合,刚性管理与柔性管理有机结合,将团队建设纳入考核内容之中,切实加强对高层次人才的管理。
