The Effect of Different Price Presentations on Consumer Impulse Buying Behavior: The Role of Anticipated Regret  [PDF]
Hong Zhou, Zhe Gu
American Journal of Industrial and Business Management (AJIBM) , 2015, DOI: 10.4236/ajibm.2015.51004
Abstract: Previous research has shown that personal qualities and shopping situations affect choice of consumer impulse buying behavior during sales promotion. When implementing a price reduction, retailers tend to favor one practice over the other. Yet how different implementations of a price promotion influence consumer impulse buying behavior has been insufficiently studied. Here, we framed a price reduction in the amount of money versus percentage on products to investigate how the underlying mechanism (anticipated regret) influences likelihood to impulse buying. Compared with percentage-off presentation, the findings indicate that presentation shown at the amount of money leads to higher anticipated regret and consumer impulse buying intention. We also find that the price level of product is the boundary condition, which plays a moderating role.
Computational Studies on Detecting a Diffusing Target in a Square Region by a Stationary or Moving Searcher  [PDF]
Hongyun Wang, Hong Zhou
American Journal of Operations Research (AJOR) , 2015, DOI: 10.4236/ajor.2015.52005
Abstract: In this paper, we compute the non-detection probability of a randomly moving target by a stationary or moving searcher in a square search region. We find that when the searcher is stationary, the decay rate of the non-detection probability achieves the maximum value when the searcher is fixed at the center of the square search region; when both the searcher and the target diffuse with significant diffusion coefficients, the decay rate of the non-detection probability only depends on the sum of the diffusion coefficients of the target and searcher. When the searcher moves along prescribed deterministic tracks, our study shows that the fastest decay of the non-detection probability is achieved when the searcher scans horizontally and vertically.
Searching for a Target Traveling between a Hiding Area and an Operating Area over Multiple Routes  [PDF]
Hongyun Wang, Hong Zhou
American Journal of Operations Research (AJOR) , 2015, DOI: 10.4236/ajor.2015.54020
Abstract: We consider the problem of searching for a target that moves between a hiding area and an operating area over multiple fixed routes. The search is carried out with one or more cookie-cutter sensors, which can detect the target instantly once the target comes within the detection radius of the sensor. In the hiding area, the target is shielded from being detected. The residence times of the target, respectively, in the hiding area and in the operating area, are exponentially distributed. These dwell times are mathematically described by Markov transition rates. The decision of which route the target will take on each travel to and back from the operating area is governed by a probability distribution. We study the mathematical formulation of this search problem and analytically solve for the mean time to detection. Based on the mean time to capture, we evaluate the performance of placing the searcher(s) to monitor various travel route(s) or to scan the operating area. The optimal search design is the one that minimizes the mean time to detection. We find that in many situations the optimal search design is not the one suggested by the straightforward intuition. Our analytical results can provide operational guidances to homeland security, military, and law enforcement applications.
Non-Detection Probability of a Diffusing Target by a Stationary Searcher in a Large Region  [PDF]
Hongyun Wang, Hong Zhou
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.73023
Abstract:

We revisit one of the classical search problems in which a diffusing target encounters a stationary searcher. Under the condition that the searcher’s detection region is much smaller than the search region in which the target roams diffusively, we carry out an asymptotic analysis to derive the decay rate of the non-detection probability. We consider two different geometries of the search region: a disk and a square, respectively. We construct a unified asymptotic expression valid for both of these two cases. The unified asymptotic expression shows that the decay rate of the non-detection probability, to the leading order, is proportional to the diffusion constant, is inversely proportional to the search region, and is inversely proportional to the logarithm of the ratio of the search region to the searcher’s detection region. Furthermore, the second term in the unified asymptotic expansion indicates that the decay rate of the non-detection probability for a square region is slightly smaller than that for a disk region of the same area. We also demonstrate that the asymptotic results are in good agreement with numerical solutions.

Performance of Stochastically Intermittent Sensors in Detecting a Target Traveling between Two Areas  [PDF]
Hongyun Wang, Hong Zhou
American Journal of Operations Research (AJOR) , 2016, DOI: 10.4236/ajor.2016.62021
Abstract: We study the problem of detecting a target that moves between a hiding area and an operating area over multiple fixed routes. The research is carried out with one or more cookie-cutter sensors with stochastic intermission, which turn on and off stochastically governed by an on-rate and an off-rate. A cookie-cutter sensor, when it is on, can detect the target instantly once the target comes within the detection radius of the sensor. In the hiding area, the target is shielded from being detected. The residence times of the target, respectively, in the hiding area and in the operating area, are exponentially distributed and are governed by rates of transitions between the two areas. On each travel between the two areas and in each travel direction, the target selects a route randomly according to a probability distribution. Previously, we analyzed the simple case where the sensors have no intermission (i.e., they stay on all the time). In the current study, the sensors are stochastically intermittent and are synchronized (i.e., they turn on or off simultaneously). This happens when all sensors are affected by the same environmental factors. We derive asymptotic expansions for the mean time to detection when the on-rate and off-rate of the sensors are large in comparison with the rates of the target traveling between the two areas. Based on the mean time to detection, we evaluate the performance of placing the sensor(s) to monitor various travel route(s) or to scan the operating area.
Absorption Rate into a Small Sphere for a Diffusing Particle Confined in a Large Sphere  [PDF]
Hongyun Wang, Hong Zhou
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.77065
Abstract: We study the problem of a diffusing particle confined in a large sphere in the n-dimensional space being absorbed into a small sphere at the center. We first non-dimensionalize the problem using the radius of large confining sphere as the spatial scale and the square of the spatial scale divided by the diffusion coefficient as the time scale. The non-dimensional normalized absorption rate is the product of the physical absorption rate and the time scale. We derive asymptotic expansions for the normalized absorption rate using the inverse iteration method. The small parameter in the asymptotic expansions is the ratio of the small sphere radius to the large sphere radius. In particular, we observe that, to the leading order, the normalized absorption rate is proportional to the (n 2)-th power of the small parameter for \"\".
The Impact of Online Additional Comments on Consumers’ Information Adoption  [PDF]
Hong Zhou, Sujuan Li
Sociology Mind (SM) , 2017, DOI: 10.4236/sm.2017.72005
Abstract: Online additional reviews, as an effective complement to network commentary system, provide an important reference during the process of consumers’ purchase and businesses’ operation decision-making. In this paper, we explored the impact of additional comments on consumers’ information adoption in different comment combinations. At the same time, we also analyzed the moderating role of consumers’ ambivalent attitude. The results show that, when initial comment is positive, compared with the consistent comments (positive initial comments and positive additional comments), consumers have a higher degree of adoption of inconsistent comments (positive initial comments and negative additional comments). On the contrary, when initial comment is negative, consistent comments (negative initial comments and negative additional comments) are more easily adopted by the consumer. Compared with the low ambivalent attitude consumers, customers with high ambivalent attitude tend to adopt negative comments.
Red or Blue? The Influence of Background Color on Promotion Value Perception  [PDF]
Yanxin Yu, Hong Zhou
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.83041
Abstract: Promotions are commonly used marketing tools for enterprises; the effectiveness of promotional posters is related to the success or failure of promotional activities. This paper embarks from two major elements of poster-promotional information and background color, and studies the effects of different promotional frames and background colors on the perceived value of consumer activity. This study divides the promotional framework into positive promotional framework and negative promotion framework. Through two experiments, the paper discusses how the matching of promotional frame and background color affects consumers value perception of promotional activities, and studies the mediating effect of perceptual diagnosis on the relationship, and the moderating effect of individual control sense on the relationship. The conclusion of the experiment is that the match between the promotional frame and the background color has an interactive effect on the value perception of the promotional activities. The experiment second verifies the existence of this interaction effect and verifies the mediating effect of perceptual diagnostics.

Zhenjun Niu, Hong Zhou
Yangtze Medicine (YM) , 2018, DOI: 10.4236/ym.2018.22008
Abstract: Objective: To understand the status of cognition of palliative nursing among nursing students at different levels, and provide a basis for palliative nursing education. Methods: 268 nursing students from different levels were investigated by the palliative nursing cognition questionnaire and Chinese version of palliative nursing knowledge questionnaire (PCQN). Results: Students with clinical probation and from non single parent family normally have higher knowledge scores than those without clinical probation and from single parent families (p < 0.05); statistical differences were observed in seven aspects of palliative care (p < 0.05); the undergraduates have higher scores, compared to students of junior college and secondary school in dimension two and total score (p < 0.05); the factors include the experience of probation and the grade getting from internship hospital. Conclusion: It’s important for schools and hospitals to strengthen the theory teaching of palliative nursing, combine clinical practice with the theory education closely and improve the teaching level of teachers, which are aimed to promote the rapid development of palliative care.
The Influence of Time Landmarks on Consumers’ Advertising Appeal Preferences  [PDF]
Chunxiu Ye, Hong Zhou
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.104036
Abstract: As one of the main carriers of corporate product promotion—advertising plays a vital role, and advertising always contains the words of time landmarks or the time landmarks embedded in its content, so this article from the two major advertising The constituent elements—time landmarks (fresh/ ending) and the type of advertising appeal (emotional/rational appeal), start to study the influence of time landmarks on the preference of consumers’ advertising appeals. This study explores the impact of time landmarks on consumer preference type’s preferences through two experiments, and studies the mediating role of self-depletion perception. Consumers who activate the fresh time landmarks prefer a rational advertising appeal, while consumers who activate the ending time landmarks prefer an emotional advertising appeal.
