The level of sunk cost and risk-taking theory have been offered as one explanation for the escalation of commitment behavior. This Study attempted to replicate Keil's study in Korea. Keil examined the level of sunk cost associated with the risk propensity and risk perception of decision-makers, and these factors are assessed for cross-cultural robustness using matching laboratory experiments carried out in three countries. The level of sunk cost and the risk perception of decision-makers contributed significantly to their continuous willingness to their project. Moreover, the risk propensity of decision-makers was inversely related to risk perception, and this inverse relationship was significantly more weak in Korea than in Singapore. These results show that the sunk-cost effect exists across cultures, and that the risk-taking behaviors are partially mediated by cultural factors.

This ethnographic study investigated aspects of negative social power in 4-year-old children and characteristics of the children who use it. The negative use of social power included taking the possessions of peers without permission, ignoring classroom rules, controlling, rejecting, and threatening others. Most children who abused social power behaved as controllers and were popular children or had a following within the group. They were physically superior to peers, of competitive disposition, and had a well-developed capacity for verbal expression; they were self-centered and had a high level of cognitive ability. Further areas for ethnographic research into the nature of the negative use of social power in young children include training in perspective taking, age differences, and factors that contribute to the development of negative social power in young children.

One way for phatic communication to be linguistically realized involves ritual activities, such as greetings and leave-takings. These conventionalized acts in medical contexts can significantly influence both transactional and interpersonal goals. The analysis in this paper confirms that exchanging rituals such as greeting and leave-taking between doctors and patients is not a simple exchange of conventionalized linguistic symbols. In addition, the use of discursive strategies means that to determine whether an expression is phatic or not, it is necessary to analyze it from the multidimensional perspective. The phaticity is established based on the negotiation between the participants during the interaction. We have found that the interrogative form of greeting like "¿Qué tal?" (How are you?) becomes a versatile resource in the medical context. Thus, professionals need to be attentive to the discourse progress, because the phaticity of the interrogative greetings (illocutionary force) is linked, in the vast majority, with the reaction of the patients. Also, the data confirms that when participants coordinate closings, the exchange of turns lengthens and the intervention of various discursive strategies for phatic communion becomes more prominent.

Recent technological advancements have had a substantial impact on consumer buying behavior. This research aims to determine the factors affecting consumer behavior related to the adoption of self-service technologies (SSTs). The intended findings of this study are expected to contribute to understanding consumer behavior towards the adoption of SSTs taking into account the logic of two main theories in this regard: the Technology Acceptance Model (TAM) and the assumptions of the Behavioral Perspective Model (BPM). This research follows a triangulation approach. Consequently, a number of semi structured interviews were conducted with experts and executive directors from selected SSTs providers in Jordan. In addition, the convenience sampling technique was employed focusing on current (or) previous users of SSTs in the public and private sectors in Jordan using a self-administrative questionnaire (66% response rate). The results confirmed the influence (direct and indirect) of previous experience and personal initiatives and characteristics on consumer intention to use SSTs. In addition, the results indicated the important role of the mediator variables namely: perceived ease of use (EOU), perceived risk (PR), and perceived usefulness (PU) on consumer attitude towards SSTs which in turn will positively affect consumer intention to use SSTs.

This study investigated the effects of critical thinking and empathy on the cultural competence of dental hygienists and students. A total of 529 dental hygiene students were randomly sampled and included as subjects. PASW Statistics for Windows ver. 18.0 was used to obtain the following results. Among the critical thinking sub-domains, cognitive integration was the highest and the lowest. Empathic ability had the highest acceptance factor among the sub-domains. Cultural competence was the highest among the sub-domains, while cultural knowledge was the lowest. According to their general characteristics, subject age, grade, religion, and economic level influenced the cultural capacity. Cultural awareness and sensitivity were high when there were foreign visiting experiences. Cultural awareness, sensitivity, skills, and knowledge were high when subjects had experienced multicultural education (p<0.05). Cultural awareness, sensitivity, skill, experience, and knowledge were correlated with critical thinking and cultural competence, among which cultural sensitivity showed the highest correlation (p<0.001). There was a correlation between cultural awareness and sensitivity, skill, and experience among the empathy and cultural competency sub-domains (p<0.001). The factors influencing cultural awareness included intellectual integration, openness, prudence, and perspective-taking (p<0.001). The factors influencing cultural sensitivity included intellectual integration, openness, and empathic concern (p<0.001). The factors influencing cultural skill included intellectual integration, creativity, and conductivity (p<0.001). The factors influencing cultural experience included prudence, objectivity, perspective-taking, and personal distress (p<0.001). Finally, the factors influencing cultural knowledge included creativity and conductivity (p<0.001). The results indicate that dental hygiene students should be equipped with cultural competence to enhance critical thinking and empathy required by the modern society and optimized dental hygiene courses should be provided for multicultural subjects.

This study identified the mediating effect of the child's emotional expression on the relationship between the mother's empathy and the child's prosocial behavior. The participants included 310 mothers of children between the ages of 2 and 5 from two kindergartens and four day care centers located in Gyeonggi-do. The mother's empathy was measured using the Interpersonal Reactivity Index. The child's prosocial behavior was measured using the Preschoolers' Prosocial Behavior Index. The child's emotional expression was assessed using a questionnaire from previous research. First, older mothers and less educated mothers showed a higher level of empathy. Mothers over the age of 30 were more likely to have the ability to imagine other roles in movies or books, and to show empathic concern than those under 36. Mothers without a college degree showed a higher level of perspective-taking than those with a college degree. Second, girls were more likely to engage in prosocial behaviors and show emotional expressions than boys. Three-year-old children were more likely to share than two-year-old children, showed more initiative than two- and four-year-old children. Third, the mother's perspective-taking and empathic concern were significantly related to the child's prosocial behavior and emotional expression. The mother's personal distress was related to the child's control over emotions and awareness of other's emotion. Finally, the child's emotional expression had a mediating effect on the relationship between the mother's empathy and the child's prosocial behavior.

Objectives: The purpose of this study was to suggest the strategies for improvement of home-delivered meal services for the elderly, to identify reasons for recipients to get started with the services and to evaluate the attitude, acceptability and adaptation of recipients to the services from the perspective of life context. Methods: The data was collected through face-to-face in-depth interviews with eighteen low-income elderly recipients of home-delivered meals and analyzed using a qualitative research method. Results: The results were deduced as four themes which comprised of long-term vulnerable socioeconomic contexts resulted in entry to the services, conflicting acceptability to the services, passive adaptation to taking the services, and positive practices to cope with supplement free meals or other services. The service participation was initiated because of a combination of prolonged, vulnerable socioeconomic contexts, including poverty and unexpected life events such as diseases, disability, living alone, aging and unemployment. With regard to taking the services, conflicting acceptability was observed: positive aspects including saving living cost and good quality of meals, and negative aspects including lack of a tailored service and feeling of stigma. Although the recipients needed an individualized service, they did not express their needs and demands for the services and they accepted the unavailability as an accustomed, prolonged vulnerable socioeconomic context. With regard to lack of tailored services, either self-solution such as modification of eating patterns or community-based network and services were used. Conclusions: We suggest that a system to concretely identify recipients' attitude, acceptability and adaptation for home-delivered meal services should be developed in the establishment of a tailored nutrition support system for the low-income elderly.
