RESUMEN

Physical attractiveness has long been established as a desirable trait in society. Physically attractive individuals are considered more competent, successful, and sociable. Numerous studies have examined the influence of makeup on physical attractiveness and its subjective psychological effects. However, the effect of nail care has not yet been examined. This study aimed to explore the psychological effects of nail care. Female Japanese participants (N = 334) completed an online questionnaire. The results showed that nail care positively elevated three aspects: positive emotions, relaxation, and vitalization. Moreover, they confirmed significant differences between receiving nail care from salon manicurists and self-performed nail care in terms of positive emotions and relaxation. The results indicated that nail care altered the appearance of the recipients' nails and their self-esteem, including their feelings, mood, and motivation. Furthermore, this study indicates that it may be preferable for both manicurists and clients not to self-disclose in-depth, as this would negate the positive effects of nail care. The study concludes with recommendations for future research.

RESUMEN

Several studies on tourism have examined the effects of vacation and travel on individuals' wellbeing. However, relatively little is known about the underlying psychological factors and mechanisms. Therefore, this study aimed to investigate the effects of a winter vacation on individuals' wellbeing. A total of 507 participants (255 men and 252 women) completed three questionnaires at three different time points. The questionnaires comprised psychological scales and items to seek demographic information so that the changes in their wellbeing could be assessed. The results revealed that people who traveled had higher subjective wellbeing than those who did not. Moreover, out of the four elements of the recovery experience, mastery was the only one influenced subsequent subjective wellbeing. The findings suggest that it is crucial to take vacations and to savor recovery experiences while off work. In particular, experiencing new and challenging events during a vacation was the most significant predictor of vacationers' subsequent wellbeing. Our results clarify what type of vacation is most effective for wellbeing. The results can help tourism practitioners manage their customers' experiences better during their vacations, and these efforts will arguably contribute not only to the wellbeing of vacationers but also to future company growth.

RESUMEN

This work aims at evaluating the sensitivity of landslide susceptibility mapping (LSM) to sampling design in lithologically-heterogeneous areas. We hypothesize that random sampling of the landslide absence data in such areas can be biased by statistical aggregation of the explanatory variables, which impact the model outputs. To test this hypothesis, we train a Random Forest (RF) model in two different domains, as follows: (1) in lithologically heterogeneous areas, and (2) in lithologically homogeneous domains of the respective areas. Two heterogeneous areas are selected in Japan (125 km2) and Romania (497 km2), based on existing landslide inventories that include 371 and 577 scarps, respectively. These areas are divided into two, respectively three domains, defined by lithological units that reflect relatively homogeneous topographies. Fourteen terrain attributes are derived from a 30 m SRTM digital elevation model and employed as explanatory variables. Results show that LSM is sensitive to a random sampling of the absence data in lithologically heterogeneous areas. Accuracy measures improve significantly when sampling and LSM are conducted in lithologically homogeneous domains, as compared to heterogeneous areas, reaching an increase of 9% in AUC and 17% in the Kappa index.

RESUMEN

The objective of this study is to empirically analyze and model the stop-go decision behavior of drivers at rural high-speed intersections in China, where a flashing green signal of 3s followed by a yellow signal of 3s is commonly applied to end a green phase. 1, 186 high-resolution vehicle trajectories were collected at four typical high-speed intersection approaches in Shanghai and used for the identification of actual stop-go decision zones and the modeling of stop-go decision behavior. Results indicate that the presence of flashing green significantly changed the theoretical decision zones based on the conventional Dilemma Zone theory. The actual stop-go decision zones at the study intersections were thus formulated and identified based on the empirical data. Binary Logistic model and Fuzzy Logic model were then developed to further explore the impacts of flashing green on the stop-go behavior of drivers. It was found that the Fuzzy Logic model could produce comparably good estimation results as compared to the traditional Binary Logistic models. The findings of this study could contribute the development of effective dilemma zone protection strategies, the improvement of stop-go decision model embedded in the microscopic traffic simulation software and the proper design of signal change and clearance intervals at high-speed intersections in China.

RESUMEN

The Thinking About Life Experiences (TALE) Scale (Bluck & Alea, 2011) has three subscales that assess the self, social, and directive functions of autobiographical memory. This study constructs a Japanese version of the TALE Scale and examines its reliability and validity. Fifteen items that assess the three functions of autobiographical memory were translated into Japanese. We conducted an online investigation with 600 men and women between 20-59 years of age. In Study 1, exploratory and confirmatory factor analysis identified that the three-factor structure of the Japanese version of the TALE Scale was the same as the original TALE Scale. Sufficient internal consistency of the scale was found, and the construct validity of the scale was supported by correlation analysis. Study 2 confirmed that the test-retest reliabilities of the three subscales were sufficient. Thus, this Japanese version of the TALE Scale is useful to assess autobiographical memory functions in Japan.

RESUMEN

This study examined the nature and origin of 'sense of nigate,' which is an awkward and uncomfortable feeling one has toward specific, relatively few others, especially in a interpersonal situation. Study 1 investigated its nature with a questionnaire administered to company employees (200 men and 45 women) and undergraduates (243 men and 205 women). Two factors were found for the sense: troublesomeness and apprehension. It should be noted that apprehension was lower for management than non-management workers. This tendency was due to the worker position, rather than his/her age. In Study 2, self-monitoring scale (Lennox & Wolfe, 1984) was administered to 60 high school students (12 men, 47 women, and one unknown), to investigate the origin of the sense. As predicted, sense of nigate had a negative correlation with the ability to modify self-presentation, and positive one with the sensitivity to expressive behavior in others.
