Based on the protection motivation theory and previous studies that discussed the effects of risk perception, perceived response effectiveness, and self-efficacy on behavioral intentions and changes in behavior, this study conducted an experiment to examine the effects of the Metropolitan Police Department's crime deterrence task force’s official Twitter account on crime prevention behavior. Information on the threat of communications fraud, the effectiveness of preventive behavior, and self-efficacy was presented via Twitter, and changes in behavioral intention, behavior, fear, effectiveness, and self-efficacy were checked over time. Participants in their 20s to 50s were assigned to a Metropolitan Police Department group presented with tweets about scams or to a control group presented with other tweets. The results of the analysis of the 60 participants in the police department group and the 49 participants in the control group showed that the presentation of information increased behavioral intention, but it did not necessarily lead to changes in behavior. Therefore, it was suggested that there may be other factors that increase behavioral intention and changes in behavior.

都道府県警察が公開する犯罪発生マップでは,カーネル密度地図(KD図)の活用が推奨されている.KD図においては,その配色パターンと階級区分の組み合わせで地図の印象は異なるが,適切な組み合わせは明らかになっていない.本研究では,犯罪発生マップの地図表現の実態調査と,2つの実験により,KD図の配色・分類手法(階級区分)が犯罪多発地域の位置推定と犯罪発生頻度の見積もりに与える影響を明らかにした.実験の結果,等量分類が犯罪多発地域の位置推定を不正確にし,また犯罪発生頻度を多く見積もらせることなどが明らかになった.結果に基づき,犯罪発生マップをKD図で表現する際に留意すべき事項などについて議論した.

1. Background and objectiveThis study examines the methodology of "individual scaling method" in order to value each person's vocabulary and viewpoints. "Individual scales" refers to evaluation items made by subjects' own terms. Thus, these scales are different from person to person. In the previous report, we proposed principal component analysis (PCA) method for evaluation data measured by individual scales. In this PCA method, evaluation object is regarded as observations, and individual scales of all subjects is regarded as variables. And, individual difference in vocabulary and viewpoint is described as difference in distribution of factor loadings vectors in principal component space. Therefore, it is difficult to analyze individual difference of each object. In this paper, methodology for analyzing individual differences of each object in individual scales method was studied and proposed.2. Methodology of analysisFor the above purpose, the application method of "partial score" used in the analysis method called MFA (MultipleFactor Analysis) was discussed. And the following method was proposed.1) Exclude subjects with low correlation between partial score and global score (principal component score).2) Use "standardized partial score" to analyze individual differences for each object.3) Correcting techniques for "ipsative data" may be necessary when analyzing individual or group differences between multiple objects.In addition, using "HCA (Hierarchical Component Analysis)" as the analysis method is expected to improve the performance of partial scores.3. Case studyAs a case study, a survey on positioning analysis for dental clinic was conducted. The background, purpose and method of this survey were described.4. Analysis and discussionPCA, MFA (Block-based PCA), and HCA were applied to the case study data, and the following results were obtained.1) The output principal component scores did not differ between the methods.2) HCA was the best in the performance of statistical tests for partial scores. This shows that reliability of partial score by HCA is higher than that of other methods.3) It was found that the positioning of the dental clinic is different between those who are positive for visiting dental clinic and those who are not.5. Consideration on Methodology of AnalysisBased on the results of analysis as a case study, methodology was further considered. First, as a criterion to exclude subjects with low correlation between partial score and global score , “R-square≧0.4” was proposed. Next, how to use FA and PCA properly was considered, and necessity of correcting techniques for "ipsative data" was discussed.6. Future tasks and prospectsThe future tasks are to apply the proposed method to many cases. And, using partial scores, it seems possible to analyze individual scale method data, including different objects for each person. It is also a future task to consider this method.

Miyashita, Kimura, & Oka (2017) demonstrated that openness in the big-five personality traits did not relate to aesthetic evaluations of paintings while the aesthetic dimension of value did. Conversely, previous studies showed that openness affects preferences for specific artistic paintings after predicting general preferences as a latent variable. Thus, the present study explored whether openness would affect aesthetic evaluation of paintings via mediating variable (i.e., aesthetic dimension of value). In our survey, 323 undergraduates were asked to evaluate 24 paintings using 4 scales of aesthetic evaluation. They were also asked to complete a questionnaire assessing their degrees of openness and the aesthetic dimension of value. Results demonstrated that openness did not directly relate to aesthetic evaluations of paintings but that it indirectly related to those via the aesthetic dimension of value. These results suggest that the aesthetic dimension of value relates to openness as a mediator of aesthetic evaluations.
