Most attempts at Bayesian analysis of neural networks involve hierarchical modeling. We believe that similar results can be obtained with simpler models that require less computational effort, as long as appropriate restrictions are placed on parameters in order to ensure propriety of posterior distributions. In particular, we adopt a model first introduced by Lee (1999) that utilizes an improper prior for all parameters. Straightforward Gibbs sampling is possible, with the exception of the bias parameters, which are embedded in nonlinear sigmoidal functions. In addition to the problems posed by nonlinearity, direct sampling from the posterior distributions of the bias parameters is compounded due to the duplication of hidden nodes, which is a source of multimodality. In this regard, we focus on sampling from the marginal posterior distribution of the bias parameters with Markov chain Monte Carlo methods that combine traditional Metropolis sampling with a slice sampler described by Neal (1997, 2001). The methods are illustrated with data examples that are largely confined to the analysis of nonparametric regression models.

The study aims to investigate methods for companies to contribute to not only social and national developments, but also on the promotion of individuals and companies by re-examining the various phenomena that define companies. The study examines the relationship between subordinate factors of social responsibility activities and job performances as well as the role of CEOs in showing authentic leadership and meaningfulness of work. A total of 312 valid questionnaires were obtained, and hypotheses were tested using regression analysis, hierarchical regression analysis, and 3-way interactions. The results suggest that corporate social responsibility activities not only enhanced the performance of the members, but also confirmed the importance of the authentic leadership of the CEO. Additionally, the role of the members in the company also showed to play a very significant role in a company's developments. The results also show that the CEO and members need to make efforts to increase ethics as well as gain more competitiveness and improve their reputation by promoting their sense of calling and feeling of compassion in the workplace. In other words, the members of the high-ranking book and the members of the relatively low position will have different degrees of information transfer and evaluation of the company policy may be different.

Purpose- This study seeks to investigate the impact of foreign remittances on private sector investment and the moderating role of banking sector development in Sub-Saharan African Countries. Research design, data, and methodology-The study has used a sample of 15 Sub-Saharan African countries and data for the years 1986 - 2017. Data was obtained from the World Bank Development Indicator (WDI) Database. Panel data diagnostic tests were conducted to ascertain the suitability of the data for regression analysis. The data was analyzed through descriptive and inferential statistics, while the hypothesis was tested through hierarchical regression analysis. Results- The finding of this study indicates that foreign remittances and banking sector development had a significant and positive effect on private investment in Sub-Saharan Africa. Besides, the banking sector development significantly moderated the foreign remittances and private sector investment relationship. Conclusions- Based on the results, the study concludes that banking sector development has an important influence on foreign remittances and private sector investment nexus. Due to the antagonistic interaction between foreign remittance and banking sector development, the study recommends the use of alternative ways of channeling remittances to private investment such as; issuance of diaspora bonds and appeal for direct investment by citizens living abroad.

The purpose of this study is to derive various clues for the establishment of marketing strategies for companies that produce and sell high-involvement products for Millennials who are not the subject of current consumption but who will lead future consumption. For this purpose, this study aimed to derive 17 factors of high-involvement product selection attributes through FGI, and its relationship on repurchase intention after make a variable through PCA. A total of 158 valid questionnaires were used, and IPA, independent sample t-test, regression analysis, and hierarchical controlled regression analysis were performed. The results showed that overall, external and internal selection factors had a positive influence on repurchase intentions, and in particular, appealing to internal and external selection factors in order to promote repurchase intention. Meanwhile, the Millennials were found to have no gender difference. Therefore, the company producing and selling high-involvement products suggests that it is necessary to make a priority effort to secure brand awareness, trust in product producers, store trust, and product self-reputation as components of internal selection factors. It was also concluded that more strategic efforts were needed to focus on and appeal to the characteristics of the Millennial itself rather than to consider gender differences.

Purpose: The purpose of this study was to identify factors in the clinical learning environment that affect clinical practice stress and anxiety in nursing students. Methods: Participants were 210 senior nursing students from two universities who had completed their clinical experience. Data were collected from self-report questionnaires and analyzed using t-test, ANOVA, and hierarchical multiple regression analysis with the SPSS/WIN 21.0 Program. Results: The mean scores for the clinical learning environment, the clinical practice stress, and anxiety were $3.16{\pm}0.68$, $2.98{\pm}0.66$, and $43.74{\pm}10.18$ points, respectively. The regression analysis showed that the clinical learning environment contributed to 13% of the stress and 20% of the anxiety in the nursing students with the conditions controlled for general characteristics, department satisfaction and social support. Conclusion: The results of this study suggest that the clinical learning environment should be carefully assessed to reduce nursing students' stress and anxiety from clinical practice. Therefore, collaboration between nursing universities and teaching hospitals is necessary to optimize clinical learning environment.

Purpose: The positive effects of health behaviors in older population are well recognized, but maintenance of health habits was more difficult than initiation. The purposes of the study were to identify predictors of health behavior based on motivation theories, and to analyze predicting power of motivational factors to explain health behaviors in older adults. Methods: The data were collected from older adults either institutionalized or living in the community. Total of 159 subjects with 72 years old in average were recruited for an interview. Hierarchical multiple regression analysis were utilized to analyze the data with age, residential type, and motivational variables. Results: The results of the multiple regression analysis showed that age and residential type explained 3% of variance in health behaviors (F=3.705, p=0.027). When motivational variables were entered, additional 56.9% of variance were explained by the model (F=33.275, p< 0.001). Among motivational variables, perceived benefits was the most important variable (${\beta}=0.346$, t=4.582, p<0.001), followed by self efficacy, emotional salience, and perceived barriers. Conclusion: Considering the importance of each motivational variable, the focus of intervention strategies to assist older adults to maintain health behaviors should be on modifiable and important motivational variables, such as self-efficacy, perceived benefits and barriers, and emotional salience.
