  • Purpose - For the past several decades, behavioral economics or behavioral decision theory has undergone rapid development. This study provides a critical review of the development of behavioral economics with a focus on what are deemed to be core theories in the field. Starting from the utility function proposed by Daniel Bernoulli in the 18th century, the development history of utility functions until the emergence of the prospect theory is thoroughly reviewed. Some of the experimental results violating the traditionally assumed utility function and supporting the prospect theory value function are summarized. The most representative principles of rational choice are transitivity, independence from irrelevant alternatives (IIA), and regularity. The development of behavioral economics has been triggered by finding counter-examples to these principles. Some of the choice behaviors discussed in this study as counter-examples to the traditional theories of rational choice are the St. Petersburg paradox; the Allais paradox; gambling behavior; and the various context effects including the similarity effect, attraction effect, and the compromise effect. The Elimination-by-Aspects (EBA) model, which was proposed as an explanation for the similarity effect, is discussed in detail as well. Based on the literature review and further analysis, this study summarizes the relationship between the context effects, prospect theory, and EBA model. Research design, data, and methodology - This study provides an extensive literature review on several important theories in the field of behavioral decision theory and adds some critical comments to the theories and the relationships among them. This study first reviews the development of utility functions. Daniel Bernoulli introduced the concept of utility function to solve the St. Petersburg paradox. In the mid-20th century, Herbert Simon proposed the "satisficing" heuristic and presented a value function with a shape different from traditional utility functions. This study highlights the strengths and weaknesses of several utility functions proposed until the emergence of the prospect theory value function. Results - This study posits that prospect theory and EBA model are the two most important theories in the field of behavioral decision theory. They can explain various choice behaviors that traditional utility maximization analysis has been unable to. The application of these models to various fields is further increasing nowadays. This study explains how prospect theory and the EBA model can be used to explain the context effects. Conclusions - The traditional economic theory relies on a single variable called "utility" in explaining consumer choice. However, this study argues that, in investigating consumer choice, several other variables should also be considered. These are the similarity among alternatives, an alternative's prototypicality within the category, the dominance relationship between alternatives, and the reference point in evaluating alternatives. Due to the development of behavioral economics, we are now closer to a more complete understanding of consumer choice behavior than in the past when we had only a single tool called utility.

  • This study identified the health, academic attainment, violence and abuse factors on predicting the conduct development and emotional symptoms in 'looked after children' placement. A sample of 1,543 children was interviewed regarding emotional and behavioral symptoms and risk factors. Logistic regression was used to assess whether selected variables predicted emotional and behavioral symptoms in 'looked after children'. All placement, health, academic, violence, and abuse factors differentiated behavioral and emotional symptom differences according to selected variables. Binary logistic regression indictors of conduct behavior symptom among 'looked after children', included gender, age, placement, health, violence, and abuse. Placement, health, reading ability, violence, and witnessing domestic violence further predicted emotional and behavioral symptoms. These findings highlight multidimensional approaches to address various vulnerability indicators that have a direct application to prevention and intervention efforts to designed for emotional and behavioral problems among children in public care.

  • The effects of grandparenting involvement and emotional attachments on emotional and behavioral development among adolescents were explored through the use of a UK cross-sectional national data of 1,566 adolescents aged eleven to sixteen years old receiving some form of grandparenting. A correlation and logistic regression analyses yielded results that supported the positive effects of grandparenting on the emotional and behavioral disorder symptoms of adolescents. The results indicate that most selected socio-demographic, grandparenting involvement, and the emotional attachment variables of grandchildren influenced the likelihood of increasing or decreasing emotional disorder symptoms among adolescents. However, no support was found for perceiving emotional attachments with grandparents as a predictor of behavioral disorder symptoms among youth, whereas socio-demographic and grandparenting involvement variables showed significant impacts on behavioral disorder symptoms. The findings highlight the importance of a systematic approach about the socio-demographic characteristics, levels of grandparenting, and emotional attachment levels with grandparents to understand youth cared for by grandparents that experience emotional and/or behavioral disorder symptoms, when intervention or prevention programs are considered.

  • The present study was investigated the effect of berberine on the development of behavioral sensitization by morphine, methampethamine, and cocaine. Repeated administration of morphine (10 mg/kg), methampethamine (2 mg/kg), and cocaine (15 mg/kg) produced behavioral sensitization in mice. Pretreatment with berberine (2 mg/kg) did not inhibit methampethamine-and cocaine-induced behavioral sensitization. (omitted)

  • This study investigated relationships among infant development, teacher's sensitivity, home literacy environment, and infant-teacher interaction in the child care setting. Verbal and behavioral interactions between 30 2-year-old infant-teacher pairs were video-recorded during free play activities; teachers' sensitivity was observed by trained observers; infant development was assessed by teachers; data on the early home literacy environment were gathered through maternal self-reported questionnaires. Data were analyzed by descriptive statistics, t-tests, and correlation analyses. Results indicated that boys showed more naming; girls showed more physical contact with teachers. Infants high in overall developmental level showed more behavioral interaction with teachers. Teacher's sensitivity correlated positively with behavioral imitating and negatively with questioning and nodding. Verbal interaction in the home correlated positively with nodding.

  • Purpose: In this study, behavioral styles of Dominance, Influence, Steadiness, and Conscientiousness (DISC) were examined and differences in job satisfaction and clinical competence among newly hired nurses were explored. Methods: For this explanatory correlational research, 176 newly hired clinical nurses were recruited from three university hospitals and one general hospital located in Seoul and Gyeonggi province. Data were collected in August, 2013 though self-report questionnaires. Results: The distribution of behavioral styles was 11.4%, 42%, 29% and 17.6% for Dominance, Influence, Steadiness, and Conscientiousness respectively. DISC behavioral styles were associated with sub-areas of job satisfaction such as professional position and doctor-nurse relationship. DISC behavioral styles were significantly associated with the total score for clinical competence and sub-areas of data collection, basic nursing skills, critical thinking, education and leadership, and attitudes toward professional development and practical skills. Multiple linear regression analysis showed that DISC behavioral styles predicted clinical competence (Adj. $R^2$=.14, F=9.42, p<.001). Conclusion: A focus on cultivating influential and steady behavioral styles among newly hired nurses can be helpful in improving job satisfaction and clinical competence. There is a need to improve interpersonal relationships through a deeper understanding of each person's behavioral style based on the analysis of DISC behavioral styles.

  • This study aims to examine the structural relationships of the consumers' understanding on the event, product satisfaction, promotional strategies, and behavioral intention in a promotional event for agricultural senary industry. The study conducted a survey among the participants in promotional events. The result showed that the understanding of promotional event had a positive effect on consumer behavioral intention, which means that the greater the understanding of The senary industry and the purpose of the event, the greater the consumer behavioral intention. The consumer satisfaction on products also had a positive effect on consumer behavioral intention, implying that the consumer behavioral intention increased when their satisfaction in terms of the taste and price of the products is higher. Further, the higher the satisfaction of the promotional strategy, the higher the consumer behavioral intention. Lastly, the promotional strategy played a mediating role between the consumer's understanding of the event and the satisfaction of the product, and the consumer behavioral intention. The result suggests that the different promotional strategies including discounts, freebies, or free-samples are able to maximize the effect of promotional events through its mediating effect.
