A comparison of neural networks to ols regression in process/quality control applications

Nam, Kyungdoo,Sanford, Clive C.,Jayakumar, Maliyakal D. The Korean Operations Research and Management Scie 1994 經營 科學 Vol.11 No.2

This study compares the performance of neural networks and ordinary least squares regression with quality-control processes. We examine the applicability of neural networks because they do not require any assumptions regarding either the functional from of the underlying process or the distribution of errors. The coefficient of determination($R^2$), mean absolute deviation(MAD), and the mean squared error(MSE) metrics indicate that neural networks are a viable and can be a superior technique. We also demonstrate that an assessment of the magnitude of the neural notwork input layer cumulative weights can be used to determine the relative importance of predictor variables.

An Exploratory Study on Maximizing Tendency and Continuance Intention of Web Sites

이규동,이재은,Clive Carlton Sanford 한국경영정보학회 2010 Asia Pacific Journal of Information Systems Vol.20 No.3

Although research on acceptance of information systems provides useful insights in understanding users’ behavior, we need to further understand factors that cause long-term or continued use. This article therefore examines the role of users’ maximizing tendency (i.e., individual differences in pursuing the best option) in continuance intention of Web sites. By controlling for disconfirmation, ease of use, and product involvement, we empirically investigate the relationships between satisfaction, usefulness, and continuance intention to online bookstore Web sites. As suggested by the information technology continuance model, the effects of satisfaction to and perceived usefulness on continuance intention to Web sites are positive for individuals with low maximizing tendency (i.e., satisficers). Satisfaction and usefulness, however, are not associated with continuance intention for individuals with a high maximizing tendency (i.e., maximizers). The implications for both researchers and practitioners are discussed.

Trust, perceived relationship investment, and the moderating role of regret proneness on continuance intention of online bookstores

이규동,이재은,Clive Carlton Sanford 한국유통경영학회 2012 유통경영학회지 Vol.15 No.2

This study investigates the roles of relational factors on continuance intention of Web sites in the consumer-business context. Based on the information technology continuance model, we explore the effects of trust and perceived relationship investment on the use of online bookstores including control variables such as satisfaction and perceived usefulness. The results of our survey (N = 191) show that there are significant relationships between trust, perceived relationship investment, satisfaction, perceived usefulness, and continuance intention of Web sites. In addition, this paper employs regret proneness to explore individual differences in the switching behavior. Regret proneness moderates the effects of trust and the perception of relationship investment on the continuance intention. For individuals with low regret proneness, trust and perceived relationship investment are not significant antecedents of continuance intention. However, the relationships are positive for those with high regret proneness. Results suggests better understanding of continued use of online distribution channels. Theoretical and practical implications are discussed.

DIFFUSION of SOFTWARE INNOVATION : A MIGRATION THEORY PERSPECTIVE

HAN JIYEON,Clive Carlton Sanford,OOK LEE 한국경영정보학회 2010 한국경영정보학회 학술대회논문집 Vol.2010 No.1

This project will theorize and validate a model of user switching of information technology (IT) products. Drawing from migration theory from human geography, we hypothesize push factors, pull factors, intervening obstacles, and individual differences as predictors of IT switching, operationalize these constructs within the IT switching context, and postulate nomological relationships to explain IT switching intention. Empirical data from a field survey of international SoC (Systems on Chip) designers on how and why they either continue to use or switch to other systems development software for multiprocessors will be used to test our hypothesized model of IT switching. This study will contribute to research by postulating a preliminary theory of IT switching that can serve as a starting point for further research in this area, providing a linkage between the IT acceptance and continuance streams of research, and presenting human geography as a referent discipline for IT usage research. For practitioners, this study alerts organizational managers, IT vendors, and systems developers to the challenges and opportunities of IT switching and suggests strategies to help enable or mitigate IT switching in their target populations

신뢰, 지각된 관계 투자 및 후회 성향의 조절 효과가 온라인 서점의 지속 사용에 미치는 영향

( Gyu Dong Lee ),( Jae Eun Lee ),( Clive Sanford ) 한국유통경영학회(구 한국유통정보학회) 2012 유통정보학회지 Vol.15 No.2

본 연구는 소비자-기업 맥락에서 웹사이트의 지속 사용에 영향을 미치는 관계적인 요소들에 대해 탐색했다. 저자들은 정보기술 지속 사용 모델에 근거해서 소비자의 신뢰와 지각된 관계 투자 노력이 온라인 서점의 지속 사용 의도에 미치는 영향을 파악했다. 본 연구는 웹사이트의 최초 수용과 수용 후 지속 사용 단계를 체계적으로 이해하기 위하여, 만족과 유용성에 대한 지각을 통제 변수로 반영했다. 유용성에 대한 지각과 만족은 웹사이트 수용시의 주요 요인이 될 수 있으나, 최초 수용 후 지속적인 사용에 있어서는 그 영향이 명확하지 않기 때문에 본 연구에서는 통제 변수로 사용되었다. 또한 소비자가 후회를 경험하는 정도를 의미하는 후회 성향이라는 개인 차이를 조절 변수로 반영했다. 설문 조사(N = 191) 결과, 신뢰와 지각된 관계 투자, 만족, 유용성, 그리고 지속 사용 의도 사이에는 유의한 관계가 있는 것으로 나타났다. 후회성향은 신뢰와 지각된 관계 투자가 지속 사용 의도에 미치는 영향을 조절했다. 즉, 후회 성향이 낮은 사람들에게는 신뢰와 관계 투자 지각이 지속 사용에 영향을 주지 못했다. 그러나 높은 후회성향을 가진 사람들에게서는 두 변수들이 긍정적으로 지속 사용 의도에 영향을 미쳤다. 이는 후회 성향이 온라인 유통 채널의 지속적인 사용에 있어서 웹사이트 전환 행동에 대한 설명과 세분화 변수로 사용될 수 있음을 시사한다. 이론적, 실무적 시사점이 본문에 논의되었다.

소셜 네트워크 사이트에서의 자기의식과 자기개방의 심리적 성과

이규동(Lee, Gyudong),이재은(Lee, Jaeeun),Clive Sanford 한국상품학회 2013 商品學硏究 Vol.31 No.1

연구목적: 사람들은 소셜 네트워크 사이트를 통해서 쉽게 자신을 표현하고 상호 교류를 하고 있지만, 이에 대한 긍정적인 성과에 대한 연구는 아직 부족하다. 이에 본 연구는 사적/공적 자기의식과 자기개방이 주관적인 안녕감과 소셜 네트워크 사이트에 대한 애착에 미치는 영향을 탐구한다. 연구설계 및 방법론: 저자들은 두 단계에 걸친 설문 조사 방법을 사용하였다. 첫 단계에서 참여자들은 자기의식 및 성격 차원에 대한 문항들을 답변하였다. 2주 후에 해당 참여자들은 소셜 네트워크 사이트 사용과 관련한 설문 및 인구통계 정보에 응답하였다. 설문은 300명의 한국 대학생들을 대상으로 진행되었다. 분석 및 연구 결과: 연구 결과, 자기개방은 소셜 네트워크 사이트에 대한 애착과 긍정적인 관계를 보였다. 또한 소셜 네트워크 사이트를 통한 자기개방은 삶의 만족, 긍정 정서 및 주관적 안녕감과도 긍정적인 관계를 보였다. 그러나 사적 자기의식은 소셜 네트워크 사이트에 대한 애착과 부정적인 관계를 보였다. 시사점 및 연구의 한계점: 사람들은 대인적 목적 달성을 위해 소셜 네트워크 사이트를 사용하며, 그 결과 자신의 주관적 안녕감을 높일 수 있다는 점을 확인하였다. 인터넷을 통한 자기표현을 촉진시키기 위해서 정책 결정자나 기업 실무자들은 안전하고 편리한 수단들을 제공할 필요가 있다. 향후 연구방향: 본 연구에서 사용한 행복에 대한 쾌락적 측면과 달리, 의미, 자아실현, 자기 수용 등과 같은 유대모니아적 행복에 대한 추가 연구가 필요하다. 공헌점: 본 연구는 정보기술의 사회적 사용을 긍정심리학적 관점으로 재조명했다. 이를 통해 소셜 네트워크 사이트에 대한 애착 현상과 주관적 안녕감을 설명하였다. Purpose: Although people easily express themselves and interact with others through social network sites (SNSs), research on the positive outcomes of using SNSs is insufficient. This article investigates the impacts of private and public self-consciousness and self-disclosure on subjective well-being. and on attachment to social network sites. Design/methodology/approach: A survey method was used. During the first stage of this survey, participants completed a test of their self-consciousness and personality dimensions. Two weeks later, they participated in another survey where they answered SNS-related questions. In this survey, participants were asked about their usage period of SNSs, the URL (uniform resource locator) of their SNSs, and other demographic variables. Three hundred participants were recruited from a large university in South Korea. Results/findings: The results indicate that self-disclosing behavior is positively related to attachment to their social network sites. Private self-consciousness, however, has a negative impact on attachment to social network sites. Self-disclosing on social network sites is positively associated with life satisfaction, positive affect, and aggregated subjective well-being. Research implications/limitations: The findings suggest that individuals use SNSs for interpersonal purposes, and thereby increase their subjective well-being. Thus, policy makers and practitioners should provide safe and convenient methods to foster this kind of self-revealing behavior on the Internet. Future work/research: Unlike hedonic aspect in this paper, an examination of the eudaimonic approach to happiness, which focuses on meaning. self-realization, and self-acceptance, is required. Originality/value: We revisit the social use of information technology from a positive psychology perspective, and explain attachment to SNSs and subjective well-being.
