Measuring servitization progress and outcome: the case of ‘advanced services’

The purpose of this paper is to establish a framework for assessing the progress and outcome of a manufacturer’s transformation towards becoming a provider of ‘advanced services’ – a complex bundling of products and services, whereby manufacturers offer capabilities and outcomes instead of products alone. ‘Advanced services’ represent the most complex offering in the current servitization trend amongst manufacturers. However, current performance measures lack the breadth and focus to assess progress or outcomes, and so support research and practice of organisational transformation efforts required. To address this gap the paper investigates how a manufacturer’s efforts to become an ‘advanced services’ provider can be comprehensively measured, and develops a framework for assessing the transformation journey towards becoming an ‘advanced services’ provider. The research method is based on (1) a systematic literature review process to create a comprehensive set of service-related performance measures that are available to assess a manufacturer’s servitization efforts, followed by (2) an engagement with an expert panel to synthesise the identified measures and create a set of ‘advanced services’ performance measures. The proposed framework is presented as a scorecard that can be used in practice to assess the progress and outcome of a manufacturer’s transformation towards becoming a provider of ‘advanced services’.     

Producing mobility: visual narratives of the rural migrant worker in Chinese television

This paper employs literatures of mobility to explore the ways which rural migrant workers in China are represented publicly via television drama. Through an analysis of the popular serial Mingong, the paper examines the underlying politics of contemporary migration in China through three themes: the territorialisation of rural and urban spaces; the embodiment of boundaries via corporeal practices and subjectivities; and the politicisation of rural migrant desires. This analysis demonstrates the significance of television in crafting discursive understandings of mobility and migrants that are suffused with contemporary governmentalities of generating but also managing and excluding migration.     

Cross Validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS) on a Sample of Ontario High School Students

This paper reports on the cross validation of the Gambling Problem Severity Subscale of the Canadian Adolescent Gambling Index (CAGI/GPSS). The CAGI/GPSS was included in a large school based drug use and health survey conducted in 2015. Data from students in grades 9–12 (ages 13–20 years) derived from the (N = 3369 students). The CAGI/GPSS produced an alpha of 0.789. A principle component analysis revealed two eigenvalues greater than one. An oblique rotation revealed these components to represent consequences and over involvement. The CAGI/GPSS indicated that 1% of the students fell into the “red” category indicating a severe problem and an additional 3.3% scored in the “yellow” category indicating low to moderate problems. The CAGI/GPSS was shown to be significantly correlated with gambling frequency (r = 0.36), largest expenditure (r = 0.37), sex (more likely to be male) (r = ?0.19), lower school marks (r = ?0.07), hazardous drinking, (r = 0.16), problem video game play (r = 0.16), as well as substance abuse. The CAGI/GPSS was cross validated using a shorted version of the short SOGS, r = 0.48. In addition the CAGI/GPSS and short SOGS produced very similar patterns of correlations results. The results support the validity and reliability of the CAGI/GPSS as a measure of gambling problems among adolescents.

A primal dual active set with continuation algorithm for high-dimensional nonconvex SICA-penalized regression

The smooth integration of counting and absolute deviation (SICA) penalty has been demonstrated theoretically and practically to be effective in nonconvex penalization for variable selection and parameter estimation. However, solving the nonconvex optimization problem associated with SICA penalty in high-dimensional setting remains to be enriched, mainly due to the singularity at the origin and the nonconvexity of the SICA penalty function. In this paper, we develop a fast primal dual active set (PDAS) with continuation algorithm for solving the nonconvex SICA-penalized least squares in high dimensions. Upon introducing the dual variable, the PDAS algorithm iteratively identify and update the active set in the optimization using both the primal and dual information, and then solve a low-dimensional least square problem on the active set. When combined with a continuation strategy and a high-dimensional Bayesian information criterion (BIC) selector on the tuning parameters, the proposed algorithm is very efficient and accurate. Extensive simulation studies and analysis of a high-dimensional microarray gene expression data are presented to illustrate the performance of the proposed method.     

重大工程复杂性与适应性组织——港珠澳大桥的案例

 重大工程通常由技术难度、系统关联性、未知因素存在巨大差异的异质性子工程组成，不同子工程往往采取不同的组织模式。传统权变理论认为，不同的外部环境需要采用不同的组织模式，组织的构建要适应外部环境的不确定性。但在重大工程中，子工程本身及其环境的复杂性均会产生不确定性，组织模式的选择和构建与子工程的复杂性具有重要的联系。因此，有必要从复杂性的视角解释重大工程的组织多样化现象。        在梳理重大工程复杂性及组织适应性研究的基础上，选择港珠澳大桥工程中的岛隧工程、钢结构工程、路面铺装工程、海事工程等子工程的组织管理实践作为研究对象，通过访谈、参与式专家和文档资料等方式获取相关数据，从复杂性视角对子工程进行分类，界定重大工程适应性组织概念，解析重大工程中不同子工程采取不同组织模式的适应性组织现象，总结构建适应性组织的路径。        基于重大工程复杂性的具体表现即工程技术方案与外部环境的关联性和认知不完备性，构建子工程复杂性评价指标体系，据此将子工程分为复杂性工程、创新性工程、关联性工程和简单工程4种类型；提出重大工程适应性组织概念；得出重大工程适应性组织构建的路径包括组织需求设计和匹配、工程主体创新和构建、组织系统形成和集成、组织职能实现和协同4个步骤。        研究旨在提出重大工程适应性组织概念，揭示重大工程组织模式选择和构建的机理及动态过程，说明重大工程组织模式与工程复杂性之间的关联性，指导其他重大工程组织管理模式的选择和构建。由于单案例研究的局限性，有必要在其他重大工程中对所提出的重大工程适应性组织概念及适应性组织构建过程进行进一步的完善和验证。     

近二十年出土文献字词对应考察研究综述

"出土文献字词对应考察研究"指以历史上某一个或几个时期的出土文献为材料,对其中一字记多词、一词用多字、字词交叉对应等复杂字词关系开展的整理研究.考察可知,近二十年出土文献字词对应考察研究的理论、视角、术语、方法都有差异.如研究视角有"单向视角与双向视角""静态视角与动态视角""封闭视角与开放视角"的不同,研究术语有字用与用字、字与词、通假与假借的区别,等等.综合而言,近二十年出土文献字词对应考察研究存在少见对复音词对应关系的考察研究、词的界定问题还有较大讨论空间、缺少动因探讨等不足.这些都是今后研究应该填补和加强的.     

当代大学生社会主义制度认同与制度自信?

制度认同在社会政治生活中占有十分重要的地位,它可以坚定人们的社会主义价值理念,唤起人们积极的制度化参与,增强人们对制度的自信心,进而增强全社会的向心力和凝聚力,巩固党执政的社会基础。制度认同与制度自信互为条件,互相促进,相辅相成。当前大学生制度认同存在问题,主要体现为对分配制度的公正性和对政治制度的规范性缺乏认同。培养大学生的制度认同与制度自信,要不断推进社会主义制度的改革和完善,要加强社会主义文化建设,要切实提高大学生马克思主义理论素养。这对于保证国家长远持续稳定发展,构建社会主义和谐社会,具有重大和深远的现实意义。

四川盆地中三叠世盐盆分布与演化特征研究

四川盆地卤水分布广泛，资源丰富, 早为世人所瞩目，中三叠统雷口坡组是四川盆地最早开采天然气和盐卤的层系之一。根据盆地雷口坡组大量钻井资料研究表明，盆地雷口坡组主要成盐期分别为雷三2 期和雷四2 期，在盆地东部和南部由于受到古隆起的影响，盐岩地层已被剥蚀难以保存，现今盐岩主要分布在开江古隆起和泸州古隆起的西部以及天井山古隆起的南部（华蓥山以西—龙门山以东的川西—川中地区）。印支运动对盆地雷口坡组盐岩在平面的迁移起着十分重要的作用，根据不同时期盐岩统计数据看，两期盐盆在平面上具有向西迁移、叠加的特征，其中川中的GS1 井就钻遇了这两期的盐岩。
