This paper is based on a modified Peltzman model from 1975 and it estimates coefficients of legal variables (alcohol law and helmet law, both defined as the highest monetary fine for violating the respective law in real terms) and socioeconomic variables (real disposable income per capital, real price of alcohol, real price of fuel, unemployment rate, number of vehicles, and secular trend) against monthly numbers of fatalities in 1991- 2012 time period by using time series OLS multiple regression analysis. The result reveals that helmet law together with unemployment rate and secular trend have a significantly reducing effect whereas real disposable income and number of vehicles have a significantly increasing effect on fatalities. Particular emphasis was laid on explaining the reducing impact of helmet law. Implications and suggestions are also addressed.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82019523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study reports on its findings on 49 risk factors by using grounded theory and conducting expert questionnaires. The identified factors are further classified into nine categories based on work system method, and a risk management mechanism is developed thereafter. Finally, two cases are selected to examine the feasibility of the mechanism. The developed mechanism is found to be a practical and proper ERP system risk management tool that can assist enterprises in identifying, analyzing, assessing, and responding to potential risks.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87444726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet most research has formulated them independently in prediction models. This paper proposes a prediction model of customer monetary spending using information on interpurchase time. Unlike previous research, we consider interpurchase time according to geometric distribution. Moreover, our monetary prediction model combines interpurchase time and an underlying (basic unit) monetary amount which is assumed as log normal distribution. This study collects empirical data to validate the proposed model and estimate its parameters. We also compare our results with those of interpurchase time following exponential distribution. The results show that our proposed model performances better at monetary forecasting than the exponential model does.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"6 1","pages":"181-194"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78704304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to cope with this problem, we use both of the advantages of support vector regression model and grey theory to construct a new grey support vector regression (GSVR) model for solving limited data with some fluctuations.

Thus, producers or marketers of cultural brands could improve consumer-brand relationships by promoting cultural stories at exhibitions associated with their brands. To attract visitors, they could arouse cultural resonance by sharing the creative ideas that inspired their unique products.

Multiple common due windows, an extension of single common due window, allow a job to fit one from multiple common due windows. We assume that the number of common due windows to be assigned to the jobs is given. Two resource allocation models are examined, namely the linear resource consumption model and the convex re-source consumption model. The actual processing time of a job is a function of its scheduled position in a sequence and its resource allocation. We aim to determine jointly the optimal common due window positions and sizes, the set of jobs assigned to each common due window, the optimal resource allocations, and the optimal schedule for minimizing an objective function which includes earliness, tardiness, common due windows assignment, makespan, and resource consumption costs. We provide some properties of the optimal schedule for the problem and propose polynomial time algorithms for all the problems considered.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"34 1","pages":"101-120"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80050282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It conducts a Modified Delphi expert consensus process and analytic network process (ANP) to explore the associations and weights of the factors in the evaluation model. The results demonstrate that the government factors, including government support and the legal system, are the most important competitive factors of the medical tourism industry. High-ranking sub-criteria, including the marketing strategy and physician training systems, are related to the government factor. Short-term treatment medical programs, such as cosmetic surgery and dentistry, are priorities for development. A friendly legal system and government-led marketing strategies are strongly suggested for development in Taiwan. Superior healthcare quality and a well-established and a physician training system are Taiwans main competitive advantages compared with the rest of Asia. The model provides an objective view for evaluating the importance of competitive factors for developing medical tourism and builds a framework to analyze the regional competition of medical tourism.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"468 1","pages":"139-156"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77739040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, the quarterly global sales volumes of Apple's iPhone are highly autocorrelated over time although the time lag is as long as 10 quarters. Based on such empirical evidence, an autocorrelated demand process referred to as fractional Brownian motion is adopted in this paper. It is assumed that there are two echelons in the supply chain: business and consumer markets. The information flows fall into four categories: demand flow, marketing info flow, uncertainty flow, and premium charge flow. The downstream agent can transfer demand uncertainty to the upstream firm (uncertainty flow) by signing a supply contract (contracting agent). The demand in the consumer market is assumed to follow a fractional Brownian motion. Based on the fractional Ito formula for the real option model, the result demonstrates that the real option value can be an increasing or decreasing function of the degree of autocorrelation in which the real option value reaches its maximum at the critical point. As a consequence, the trading price determined in the supply contract without considering the autocorrelation of demand could be significantly undervalued or overvalued. In other words, to ensure a fair game in a contracting activity, the upstream agent should charge more for the trading price depending on the degree of autocorrelation in demand.","PeriodicalId":39953,"journal":{"name":"International Journal of Information and Management Sciences","volume":"33 1","pages":"35-49"},"PeriodicalIF":0.0,"publicationDate":"2014-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78755532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Raw data analysis indicated that 40% of the respondents were willing to pay for in-flight WIS. Among the respondents who were willing to pay, the maximal and minimal stated WTP for unlimited use of in-flight WIS were US$48 and US$6, respectively.
