Creating value from Social Big Data: Implications for Smart Tourism Destinations     

Pasquale Del Vecchio  Gioconda Mele  Valentina Ndou  Giustina Secundo 《Information processing & management》2018,54(5):847-860

This paper aims to demonstrate how the huge amount of Social Big Data available from tourists can nurture the value creation process for a Smart Tourism Destination. Applying a multiple-case study analysis, the paper explores a set of regional tourist experiences related to a Southern European region and destination, to derive patterns and opportunities of value creation generated by Big Data in tourism. Findings present and discuss evidence in terms of improving decision-making, creating marketing strategies with more personalized offerings, transparency and trust in dialogue with customers and stakeholders, and emergence of new business models. Finally, implications are presented for researchers and practitioners interested in the managerial exploitation of Big Data in the context of information-intensive industries and mainly in Tourism.  相似文献   

工作资源对高校图书馆员敬业度影响机制的实证研究     

康超群  杨晴 《图书情报工作》2019,63(17):69-76

[目的/意义]探讨工作资源对高校图书馆员敬业度的影响与机制，以期为高校图书馆实施人力资源管理和提升图书馆员的敬业度提供参考。[方法/过程]选取湖南各高校图书馆的358名馆员为研究对象，考察工作资源对高校图书馆员敬业度的预测作用以及心理资本与组织承诺在两者之间的中介作用。[结果/结论]描述性统计与差异分析、相关分析和逐步回归分析的结果表明，不同性别的高校图书馆员在组织承诺量表得分上存在显著性差异，男性馆员组织承诺得分显著高于女性，不同性别馆员在其余得分上均不存在显著性差异。不同婚姻、年龄、学历、职位、职称者在各量表得分上均不存在显著性差异。高校图书馆员工作资源、心理资本、组织承诺与敬业度的两两相关都达到统计显著性水平。工作资源对高校图书馆员的敬业度具有正向预测作用，心理资本和组织承诺能够在工作资源对高校图书馆员敬业度的影响中起部分中介作用。丰富高校图书馆员工作资源，增进其组织支持感，增强其心理资本和组织承诺，是促进高校图书馆员敬业度提升的有效路径。  相似文献

Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com     

Wenchao Ma  Jimmy de la Torre 《Educational Measurement》2019,38(2):114-115

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.  相似文献   

混合式教学在安全系统工程中的应用模式研究     

孙晓元  李俊吉  谢建林 《教育教学论坛》2020,(16):264-267

为实现利用较少学时来丰富教学内容、改善教学质量、革新教学方法和提升教学效率的基本目标,文章以安全系统工程这一核心课程为研究对象,通过梳理课程脉络结构、分析理论知识体系、调研学生期望与社会需求等环节,初步构建了基于“互联网+”的“线上”+“线下”混合式教学模式。实证研究表明,混合式教学模式的应用有助于提升教学质量,增强学习效果,并为教学目标的达成和人才培养的实现提供有力支撑。  相似文献   

异议模式及其语用功能探究     

杨佩佩 《鸡西大学学报》2014,(1):126-129

在交流日益频繁的今天,表达异议也日显重要。作为一种本质上不合作、不礼貌的重要言语行为,异议却往往容易被研究者忽视。基于异议在日常交往、辩论访谈等活动中的实证分析,可以尝试对其主要模式进行分类,探讨不同模式的语用功能。并且为了便于实践中表达异议时模式的选择,影响选择的强弱、显隐、直接间接三对参数被提出。研究旨在补充异议这一言语行为在语用学中的研究,促进人们更好地交换意见。  相似文献   

Reconsidering Reliability in Classroom Assessment and Grading   总被引：1，自引：0，他引：1  

Jeffrey K. Smith 《Educational Measurement》2003,22(4):26-33

It is argued that classroom assessment evolves from a different set of issues and demands from more traditional measurement concerns and that approaches to reliability developed from traditional concerns are not appropriate for most classroom settings. The assessment and grading issues for high school instruction are examined from the perspective of reliability. An alternative conceptualization of reliability, sufficiency of information, is proposed and explored. This conceptualization is based on the argument that at a rudimentary level, reliability theory is based on the notion of having enough information to make decisions or draw inferences.  相似文献

Testing Measurement Invariance Across Unobserved Groups: The Role of Covariates in Factor Mixture Modeling     

Yan Wang  Eunsook Kim  John M. Ferron  Robert F. Dedrick  Tony X. Tan  Stephen Stark 《Educational and psychological measurement》2021,81(1):61

Factor mixture modeling (FMM) has been increasingly used to investigate unobserved population heterogeneity. This study examined the issue of covariate effects with FMM in the context of measurement invariance testing. Specifically, the impact of excluding and misspecifying covariate effects on measurement invariance testing and class enumeration was investigated via Monte Carlo simulations. Data were generated based on FMM models with (1) a zero covariate effect, (2) a covariate effect on the latent class variable, and (3) covariate effects on both the latent class variable and the factor. For each population model, different analysis models that excluded or misspecified covariate effects were fitted. Results highlighted the importance of including proper covariates in measurement invariance testing and evidenced the utility of a model comparison approach in searching for the correct specification of covariate effects and the level of measurement invariance. This approach was demonstrated using an empirical data set. Implications for methodological and applied research are discussed.  相似文献   

A Simple Model to Determine the Efficient Duration of Exams     

Jules L. Ellis 《Educational and psychological measurement》2021,81(3):549

This study develops a theoretical model for the costs of an exam as a function of its duration. Two kind of costs are distinguished: (1) the costs of measurement errors and (2) the costs of the measurement. Both costs are expressed in time of the student. Based on a classical test theory model, enriched with assumptions on the context, the costs of the exam can be expressed as a function of various parameters, including the duration of the exam. It is shown that these costs can be minimized in time. Applied in a real example with reliability .80, the outcome is that the optimal exam time would be much shorter and would have reliability .675. The consequences of the model are investigated and discussed. One of the consequences is that optimal exam duration depends on the study load of the course, all other things being equal. It is argued that it is worthwhile to investigate empirically how much time students spend on preparing for resits. Six variants of the model are distinguished, which differ in their weights of the errors and in the way grades affect how much time students study for the resit.  相似文献
