B创新之难？公司创业的禀赋效应/B

公司创业是现有企业重塑活力的契机。面对机会采纳/替代两种常见的模式选择,决策者有何种表现？通过对277名企业家调研,协方差分析和分组回归分析结果表明,机会替代模式下的决策速度、认同度显著低于机会采纳,而正确度略高。进一步分析了机会识别与决策效标之间随着模式变化引起的调节作用。     

Reprint requesting: A possible adjunct to citation analysis for judging research: Preliminary questions and findings

Interest in the quality of published research is evident across the range of disciplines including education. Several comprehensive studies either sponsored or published by the American Educational Research Association attest to this fact. In the sciences, citation analysis is attracting interest as a methodology for assessing research. The procedure has both theoretical and practical promise. The present study considers an overlooked source of information, reprint requesting, as a possible adjunct to citation analysis. The study stems from the questionnaire responses of 24 reprint requestors for an article by the authors. Requestor characteristics, motives, and reprint uses are considered. Implications for further research are advanced.

Association of maternal developmental disorder traits with child mistreatment: A prospective study in Japan

Maternal mental disorders are known risk factors for child mistreatment. However, little is known about the involvement of maternal developmental disorder traits. The aim of this study was to examine maternal traits related to Pervasive Developmental Disorder (PDD) and Attention Deficit Hyperactivity Disorder (ADHD), and their possible association with child mistreatment. Maternal PDD and ADHD were assessed through a self-administered questionnaire (N = 846) during mid-pregnancy using the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS) and Adult ADHD Self-Report Scale (ASRS). The mothers completed another questionnaire on child mistreatment when the offspring was approximately 18 months of age. The associations between maternal PDD and ADHD traits and child mistreatment score were analyzed using linear regression models adjusted for covariates. Mothers who exhibited stronger PDD traits showed significantly higher child mistreatment score, even after adjustment for maternal characteristics at baseline and ADHD traits. At the same time, ADHD traits were significantly associated with child mistreatment after adjustment of covariates, although the association became non-significant after adjustment of PDD traits. Mothers who showed PDD and ADHD traits during pregnancy were more likely to mistreat their children. It is essential to educate mothers with such traits with appropriate, easy-to-follow childcare instructions, preferably in simple language combined with pictorial aids.     

Big data analytics in health sector: Theoretical framework,techniques and prospects

Clinicians, healthcare providers-suppliers, policy makers and patients are experiencing exciting opportunities in light of new information deriving from the analysis of big data sets, a capability that has emerged in the last decades. Due to the rapid increase of publications in the healthcare industry, we have conducted a structured review regarding healthcare big data analytics. With reference to the resource-based view theory we focus on how big data resources are utilised to create organization values/capabilities, and through content analysis of the selected publications we discuss: the classification of big data types related to healthcare, the associate analysis techniques, the created value for stakeholders, the platforms and tools for handling big health data and future aspects in the field. We present a number of pragmatic examples to show how the advances in healthcare were made possible. We believe that the findings of this review are stimulating and provide valuable information to practitioners, policy makers and researchers while presenting them with certain paths for future research.

A case of cooperation in the European OR education

European cooperation is a relevant subject that contributes to building a competitive network of high education institutions. A case of teacher mobility on behalf of the Erasmus programme is presented: it considers some Operations Research topics and the development of the Lego on My Decision module. The module considers eight lecture hours in four sessions: (i) the introductory session, to focus on the basics of computational linear algebra, linear programming, integer programming, with computational support (Excel®); (ii) the interim session, to address modelling subjects in a drop by-session; (iii) the advanced session, on the sequence of (i), to consider uncertainty and also how to use multi-criteria decision-making methods; (iv) the final session, to perform the evaluation of learning outcomes. This cooperation at European level is further exploited, including curricula normalisation and adjustments, cultural exchanges and research lines sharing in the idea of promoting the mobility of students and faculty.
