An economic-statistical design of double sampling control chart

The double sampling (DS) chart can reduce the sample size when monitoring the process mean. In this study, Duncan's cost model was modified by adding the statistical constraints to develop the design model of DS chart for the optimization of design parameters—sample size, control limit coefficient, warning limit coefficient and sampling interval. A numerical example was provided to illustrate the use of this model. A sensitivity analysis of the effects of model parameters and statistical constraints on the optimal design of DS chart was also performed.

Features of Tradi tional Arab Management and Organization in the Jordan Business Environment

Abstract

Re search into Arab man age ment and or ga ni za tion is recent and en tails a con tra dic tory vi sion about what type of man age ment is found in Arab busi ness or ga ni za tions. This pa per sug gests that at this in-cip i ent stage of re search into Arab man age ment and or ga ni za tion, the pri mary ob jec tive of re search should be to ex plore the main fea tures of Arab man age ment in an at tempt to de velop Arab man age ment and ad -vance its or ga ni za tion. The pa per, based on the out come of a com par ative em pir i cal re search, takes into con sid er ation ma jor the o ret i cal and meth od olog i cal short com ings of re lated re search and at tempts to build a ‘bal anced’ pic ture of Arab man age ment and or ga ni za tion. Evidence in di cates that Arab man age ment and or ga ni za tion in Jor dan are, largely, tra di tional and man i fested in spe cific fea tures (lim ited future ori en ta tion and ex ces sive lack of del e ga tion of au thor ity) re flect ing on their sys tems and prac tices.     

Satisfaction measures with monetary and non-monetary components: Hotel’s overall scores

Hotel scores are critical indicators of satisfaction. However, the diversity of methodologies for calculating these indicators leads to notable differences. To explore such discrepancies, this study investigated the differences when monetary and non-monetary components are included in the measures of satisfaction. The empirical test conducted on over 26,000 hotels revealed that exclusively using non-monetary components in satisfaction measures (e.g., arithmetic mean of non-monetary attributes) leads to higher values than using monetary measures of satisfaction (e.g., value for money). The deviations between attribute performance and its expected value explained the difference between both satisfaction measures. In addition, the attributes to which people seem to be monetarily sensitive are “comfort,” “staff,” and “services.” This study provides a tool for decision-makers to identify the best method for communicating the hotel’s satisfaction measures via its position in the market and attributes that require reinforcement.

Unveiling the cloak of deviance: Linguistic cues for psychological processes in fake online reviews

Although fake online reviews have been gaining more attention from both academics and practitioners, little effort has been made to explore the linguistic characteristics of the psychological processes related to fake reviews. This research proposes four linguistic cues (i.e., affective, cognitive, social, and perceptual) related to a reviewer’s psychological processes and explores their relationships with fake reviews while examining the influence of time distance and reviewer location on these reviews. The results of logistic regression analysis of 43,496 reviews from Yelp.com suggest that affective, social, and perceptual cues are significantly related to fake reviews with the presence of the significant effects of time distance and reviewer location. Further, the results of post-hoc analysis confirm that the effect of photos on fake reviews is limited. This study contributes to the body of knowledge on online reviews and interpersonal deception theory, providing valuable implications for practitioners in the hospitality and tourism industry.     

The association between spatial attributes and neighborhood characteristics based on Meituan take-out data: Evidence from shanghai business circles

The success of a city increasingly depends on its role as a consumer centre. The new form of consumption is increasingly playing the leading role in urban consumption growth. Based on Meituan take-out data, this paper investigates quantitatively the spatial differences and explores the associations of the number of take-out with neighborhood characteristics on the scale of business circles in Shanghai by spatial econometric model. The results show that: (1) the average order quantity and consumption amount have the gradient consumption trend of the inner ring > the middle ring > the outer ring > the suburban ring. The spatial distribution of take-out in business circles is bounded by the Huangpu River, with an obvious pattern of more in the west and less in the east. (2) Three types of food distributions, traditional take-out, fashion casual take-out and supermarket and fresh take-out within business circles have obvious differences. In many business circles, fashion and leisure food delivery is significantly higher than traditional food delivery. Supermarket and fruit and vegetable take-out is scattered among business circles and is evenly distributed around the inner ring. (3) Economic level, population concentration, office and traffic factors have significant effect on the number of take-out. In detail, the impact on the volatility of dependent variables is as follows: catering industry > the number of white collars > population density > per capita consumption > traffic facility. This study proposes that office and catering industry, multi-centre city and traffic accessibility should be further strengthened in the coordinated development of Shanghai business circles so as to improve take-out economy.
