Bringing Computational Thinking to STEM Education
No full textAbstractToday, as advanced technologies and cloud computing tools emerge, it is imperative that such innovations are sustained with knowledge and skill set among STEM educators and practitioners. In this paper, the author reports on a project, HBCU-UP II, that works on bringing Computational Thinking to Science, Technology, Engineering, and Mathematics (STEM) disciplines. A Computational-Thinking based strategy is adopted to enforce thinking computationally in STEM gate-keeping courses. The paper presents framework, implementation and outcomes. This on-going project contributes to efforts to establish computational thinking as a universally applicable attitude that is meshed within STEM conversations, education, and curricula. This paper will be particularly useful for researchers interested in Computational Thinking and its applications in STEM education, in particular and higher education in genera
Developing an Instrument for Measuring Electronic Shopping Service Quality: E-SQUAL
Get PDFIn contrast to service quality in traditional facilities (e.g., stores, restaurants, clinics) that enjoyed an extensive research during the last 20 years and resulted in a solid base for service quality measurement and management, service quality that is delivered via the web, termed here electronic service quality, lacks maturity. The present study develops and validates an instrument for measuring electronic service quality of online shopping sites. Using two independent datasets, a conceptual framework of e-service quality is proposed and empirically tested. This research develops an E-SQUAL scale consisting of six dimensions: information quality, web usability, reliability, responsiveness, assurance and personalization. The developed scale demonstrates strong psychometric properties in terms of reliability and validity. Conclusion, implications and limitations of the study are presented
HeWEK: Measuring the Health Website Quality From the Perception of the African American
Get PDFUnintentionally, the growth of health websites deepened health disparities between population subgroup as it considers the perception of some sub-populations and ignore the needs of others when designing health websites. This paper presents a study that aims onto considering the perception of the African American in identifying the quality attributes of health websites. Based on focus group research and two-round factor analysis, findings indicate that quality of health websites is a function of dimensions of Aesthetic Design’, ‘Website Usability’, ‘Information Quality’, ‘Information Architecture’, ‘Responsiveness’, ‘Trust’, ‘Identity’, ‘Appropriateness to Culture’, and ‘Learnability’. The paper provides useful messages for website designers, website content mangers, usability practitioners, and web-based healthcare program managers. Also, theoretical implications and limitation of the study are presented
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Key Dimensions of E-commerce Service Quality and Its Relationships to Satisfaction and Loyalty
Get PDFEvidence exists that one successful strategy to satisfy and retain customers is offering superior service quality. Motivated by the growing interest in e-commerce, we focus our research questions on identifying the key dimensions of e-commerce service quality and its relationships to customer satisfaction and loyalty. In exploring answers to our research questions a hypothesized model is proposed and empirically tested using a research survey with 370 online shoppers. Salient results include: (1) key dimensions of e-commerce service quality are website usability, information quality, reliability, responsiveness, assurance and personalization; (2) customer satisfaction is influenced mostly with the perception of reliability, while customer loyalty is affected by the perception of assurance; (3) customer retention is predicted by the customer satisfaction index. Results of the study contribute to the nascent body of research in e-service quality and offer unique insights for managers of online firms on how to manage the quality of their e-commerce e-service
