Consumers earn a number of points for every purchase and then they can exchange a specified number of points for a desired reward in a typical loyalty program. The immediate payoff of their effort given as points is not the real reward they actually care about. It is merely an instrument (or medium) which has no value in itself. In a real world, consumers frequently choose the option with a bigger medium even though the economic value of the option is not changed by the medium. We call it 'medium effect'. In this study we explored if the size of medium affects on consumers' preferences. For this we controlled the reward options with three types of medium (small, medium, big) and measured the magnitude of preference difference among the three types of reward options. In addition, we manipulated comparability of reward options with wine and gas discount coupon. We confirmed that choosing one of two wines was easier than that of the two gas coupons. 164 respondents were allocated into three experimental groups and one control group. In three experimental groups, the ratios of the focused reward option's medium to the compared reward option's medium were different. For example, the focused reward option has 10 million points whereas the compared reward option has 10 million points for 1 million won purchase amount in the first group. Then each respondent was asked to choose one of two loyalty programs (focused program vs. compared program) in two different conditions (comparability between reward options: easiness vs. difficulty). To compare the medium effects among the experiment conditions we used chi-squares tests. The empirical results show the medium effect increases and then decreases as the ratio of reward mileages/points to purchase amount increases. Additionally, they let us know that comparability of alternatives affects on the medium effects depending on the ratio of reward mileages/points to purchase amount.

In three experimental grounds, the ratios of the focused reward option's medium to the compared reward option's medium were different. For example, the focused reward option has 10 million points whereas the compared reward option has 10 million points for 1 million won purchase amount in the first group. Then each respondent was asked to choose one of two loyalty programs (focused program vs. compared program) in two different conditions (comparability between reward options. easiness vs. difficulty). To compare the medium effects among the experiment conditions we used chi-squares tests. The empirical results show consumer preference increases and then decreases as reward mile-ages/points given according to purchase amount increase. Additionally, they let us know that comparability of alter natives affects change of consumer preference by reward mileages/points.

Purpose: This study aimed to identify the influence of effort-reward imbalance and job satisfaction on turnover intention among hospital nurses. Methods: Data were collected from January 28 to February 10, 2022, from 237 nurses from five hospitals including clinics, general hospitals, and tertiary care hospitals located in B city. The collected data were analyzed using descriptive statistics, t-test, ANOVA, the Scheffe test, Pearson's correlation coefficients, and multiple linear regression analysis, using SPSS/WIN 26.0. Results: The average of the effort-reward ratio, an indicator of effort-reward imbalance, was 1.67±0.66, and 86.5% of the participants had a value of 1 or more. The mean job satisfaction and turnover intention were 3.32±0.48 and 3.69±0.89 on a 5-point scale, respectively. Multiple regression revealed that factors affecting turnover intention among hospital nurses included effort-reward imbalance (β=.30, p<.001) and job satisfaction (β=-.32, p<.001), and these variables explained 29.0% of turnover intention. Conclusion: These findings indicate that effort-reward imbalance and job satisfaction are associated with turnover intention. Therefore, to decrease the turnover intention of hospital nurses, interventions and policies should be prepared to resolve the nurse's effort-reward imbalance and increase job satisfaction at regional or national level hospitals.

This study explores incomplete decision-making dynamics on reward-based crowdfunding platforms, focusing on temporal and social factors influencing backers' decisions. Utilizing the temporal aspect (i.e., pledging campaign phase) and social aspect (i.e., current pledged amount ratio) as stimuli within the stimulus-organism-response framework, our findings reveal that nearly 50.9% of respondents change their initial decisions, highlighting widespread incomplete information processing. Backers are more prone to altering decisions under heightened time pressure and display herding behaviors. Furthermore, backers exhibit an increased likelihood of changing decisions under heightened time pressure, coupled with a greater chance that the pledged goal amount will not be achieved. The study discusses theoretical and practical implications.

Looking back at the last 10 years of the enactment of the Game Industry Act, the law was revised as a regulation rather than a promotion of the game. The objective of this study is to investigate where game regulation originated and derived through the history of those, and to find out what areas were missed, and to solve the tangled threads by regulation. For this purpose, we reviewed the implications of 10,000 won per hour, and discussed alternatives. Data were collected and analyzed on the basis of a review of regulatory literature and in - depth interviews with experts. When regulating games, we found that the side effects were further amplified by simply regulating the amount. Especially, we found that the vicious cycle in which functions such as indication, hit repeatedly, and automatic progress are made and immediately following prohibited is repeated. The point at which there is a sharp interest between the game user and the game operator in the game progression is the 'reward ratio for betting'. This is the key to protecting users. This could be a regulation considering the mechanism of the game. If the regulatory paradigm shifts in the future due to game regulations that take into account the 'reward ratio for betting' in the future, it is expected to minimize the side effects of price regulation and create a sound game ecosystem.

We devise a collaboration construction method based on the SPRT (Sequential Probability Ratio Test) for malware detection in IoT. In our method, high-end IoT nodes having capable of detecting malware and generating malware signatures harness the SPRT to give a reward of malware signatures to low-end IoT nodes providing useful data for malware detection in IoT. We evaluate our proposed method through simulation. Our simulation results indicate that the number of malware signatures provided for collaboration is varied in accordance with the threshold for fraction of useful data.

Construction Projects have many participants by characteristic, scale and contract. Those also have complicated communication structure. So, claim and dispute occur continuously for conflicting communication. In many claim and dispute cases, it usually occurs between builder and owner. Unfair practices by owners position cause main claim and dispute. This study analyses judgment type, cause and compensation ratio in korean commercial arbitration case and provides the dispute information for builder that has weak position by contract. It draws analysis information for managing and controlling dispute that order type, judgement type, cause and failure case. Using these analysis information, it hopes to help inducement of dispute agreement and save time and economic damage for builder during construction. It also hopes to rise construction completeness by providing dispute management information.

Purpose: To investigate the work associated stress and nicotine dependence among law enforcement personnel in Mangalore, India. Materials and Methods: A cross-sectional questionnaire survey was conducted among law enforcement personnel in Mangalore, India. Demographic details, stress factors experienced at work and nicotine dependency were the variables studied. The extent of stress factors experienced at work was assessed using the Effort-Reward Imbalance scale (ERI). Nicotine dependence was measured using the Fagerstrom Test for Nicotine Dependence (FTND) and the Fagerstrom Test for Nicotine Dependence-Smokeless Tobacco (FTND-ST). Logistic regression was used for the statistical analysis. Results: Three hundred and four law enforcement personnel participated in the study, among whom 68 had the presence of one or more habits like tobacco smoking, tobacco chewing and alcohol use. The mean effort score was $15.8{\pm}4.10$ and the mean reward and mean overcommitment scores were $36.4{\pm}7.09$ and $17.8{\pm}5.32$ respectively. Effort/Reward ratio for the total participants was 1.0073 and for those with nicotine habit was 1.0850. Results of our study demonstrated no significant association between domains of ERI scale and presence of habits but work associated stress was associated with the presence of one or more habits. Compared to constables, head constables had 1.12 times higher risk of having a nicotine habit. Conclusions: Our study implies job designation is associated with nicotine habits. However, there was no association between work associated stress and nicotine dependence among law enforcement personnel in Mangalore.

Background: In contemporary China, most parents are dual-earner couples and there is only one child in the family. We aimed to examine the associations of parents' work stress with suicidal ideation among the corresponding adolescent. We further hypothesized that low parental support experienced by adolescents may mediate the associations. Methods: Cross-sectional data from school students and their working parents were used, with 907 families from Kunming City, China. Stress at work was measured by the effort-reward imbalance questionnaire. Perceived parental support was assessed by an item on parental empathy and their willingness to communicate with the adolescent. Suicidal ideation was considered positive if students reported thoughts about suicide every month or more frequently during the previous 6 months. Logistic regression was used to examine the associations. Results: We observed that parents' work stress was positively associated with low parental support, which was in turn associated with adolescent suicidal ideation. The odds ratio for parents' work stress and adolescent suicidal ideation was 2.91 (95% confidence interval: 1.53-5.53), and this association was markedly attenuated to 2.24 (95% confidence interval: 1.15-4.36) after additional adjustment for parental support. Notably, mothers' work stress levels exerted stronger effects on children's suicidal ideation than those of fathers. Conclusion: Parents' work stress (particularly mother's work stress) was strongly associated with adolescent's suicidal ideation, and the association was partially mediated by low parental support. These results need to be replicated and extended in prospective investigations within and beyond China, in order to explore potential causal pathways as a basis of preventive action.

This study investigates customers' different behavior in accumulating and redeeming points and focuses on the moderating effect of usage level. We measure the hedonic accumulation and redemption ratio and usage level using loyalty program transaction data and link them to the survey data of loyalty and satisfaction. By doing so, we examine the effects of hedonic accumulation and redemption ratio on a consumer's loyalty intention and his or her satisfaction and the moderating effect of usage level. The result shows that there is a significant positive effect of hedonic accumulation and redemption ratio on customer loyalty and the mediating role of satisfaction on customer loyalty in both stages. And accumulation and redemption most importantly, we find an interaction effect of usage level on outlet type in point redemption stage while no effect in accumulation stage. That is if customers accumulate and redeem points at a hedonic outlets in both stages, it will give him a feeling of satisfaction and finally it will enhance the loyalty toward the focal loyalty program. And light buyers' loyalty increase more than those of heavy buyers when they redeem points in hedonic outlet. Our findings will help marketing managers of loyalty program to apply the effective segmentation strategy to the reward program which affects the customer's satisfaction and loyalty.
