Beggars can be choosers: Resource scarcity,dynamism, search activities,and their joint impact on performance

Research on firm search stresses the need for firms to adapt and align concurrently with their environment to optimize the ability to sense and seize opportunities for sustained performance. We postulate resource scarcity as an important contingency factor for the search-performance relationship, and assess its joint influence with high and low dynamism. Using a dataset spanning 23 years, we examine the performance implications of combinations of internal and external exploratory and exploitative search in resource-scarce environments, under conditions of high and low dynamism. We find that resource scarcity is an important condition for performance stemming from exploratory and exploitative search: even under conditions that involve low dynamism, but joined with resource scarcity, firms may benefit from pursuing exploratory and exploitative knowledge simultaneously.

于根元先生的语言规划观

于根元先生的语言规划观主要体现在“语言规范观”“语言主体多样观”“语言服务观”三个方面。在语言规划研究方面,于先生提出了许多具有鲜明特色的重要命题,如语言规范的参照项是交际值、检验规范的成效是对语言生活的影响、语言规范制定时应重视语言的可预测性、规范就是服务等,这些命题如今看来,依然具有学习借鉴的理论意义和实践价值。     

《粮油食品工艺学》课程思政元素的挖掘与设计

文章从课程建设是思政教育的"主战场",在《粮油食品工艺学》课程中的嵌入性有待加强.围绕《高等学校课程思政建设指导纲要》中习近平新时代中国特色社会主义思想、社会主义核心价值观、中华优秀传统文化、宪法法治教育以及职业理想和职业道德教育等5点内容重点挖掘课程思政元素,并设计了包括确定课程思政目标、重构课程思政内容、融入课程思政活动和实施课程思政评价等四个步骤的课程思政框架.通过将食品专业知识教学与课程思政教学有机结合,实现培养学生专业技能和引领价值塑造的双重教学目标.     

视频UGC流行度影响因素研究——基于Bilibili网站数据

[目的/意义]Web 2.0环境下,短视频UGC新形式的Vlog有效促进了用户间的交流互动及平台的活跃.目前针对Vlog的研究集中于讨论Vlog的分享动机及传播后的影响,但在海量信息传播的社交平台,并非所有的Vlog都有显著的传播效果,但现有文献鲜有关注Vlog流行度的影响因素.[设计/方法]聚焦Vlog的视频特征(视频时长、视频质量以及弹幕数量)与发布者特征(专业性、个人声誉以及个人等级),提出了基于信号理论的研究模型.通过爬取Bilibili平台的18431条Vlog有效数据,采用实证分析方法对模型进行了验证.[结论/发现]视频时长对Vlog流行度产生负向影响,视频质量、弹幕数量、专业性以及个人声誉具有显著的正向影响,而个人等级对Vlog流行度正向影响的假设不成立.该分析结果丰富了已有关于Vlog流行度的研究,并为个人及平台提升Vlog传播效果提出了相关的对策建议.     

顾客第一论

“顾客第一”有其特定的内涵,它充分体现社会主义企业的根本目的,因而是企业所有经营观念中的一个根本性观念,也是企业生产经营的一个根本指导思想。企业要实现其双重目的,促进物质文明和精神文明建设的发展,并树立各种现代经营观念,就必须坚持顾客第一。

Chinese version of the OSI: A validation study

This article examines the construct validity of the Occupational Stress Indicator (OSI) in its Chinese version as well as its criterion-oriented validity against self-reported data on absenteeism and accidents, using a final sample of 1054 workers in the Chinese manufacturing and power industries. The divergent and convergent validities of five of the OSI scales—Job satisfaction, Physical ill-health, Mental ill-health, Type A behaviour and Control—were examined by a multimethod-multitrait matrix technique. Results indicated that the Chinese OSI had fairly good validity in relation to other well-established measures as well as relevant organizational behaviours.     

Energy conservation through resource-aware movement in heterogeneous mobile ad hoc networks

Energy conservation in mobile ad hoc networks is of paramount importance because most mobile nodes usually have very limited energy supply. Previous research on this issue focused on the design at the network or MAC or physical layer. In this paper, we study this problem from the new perspective of node mobility, i.e., analyzing the impact of node movement on energy conservation. In particular, armed with the inherent resource heterogeneity in mobile ad hoc networks, we propose a novel resource-aware movement strategy to make better use of some powerful nodes to achieve energy conservation. We also formulate the resource-aware movement as a NP-complete distance-constrained least-cost (DCLC) routing problem and propose an efficient heuristic solution. Extensive simulations have been used to demonstrate the effectiveness of the proposed schemes.
