Causal attributions of dementia among Korean American immigrants

To better understand conceptualizations of dementia, this study explored causal attributions of dementia among 209 Korean Americans, using a self-administered questionnaire in Korean. Findings show that Korean Americans endorsed various causal attributions. Factor analysis yielded 3 dimensions of their attributions including psychological, physical/environmental, and cognitive/social. Bivariate analyses showed that younger age and higher education were related to more physical/environmental attributions, and younger age was related to more cognitive/social attributions. The study provides an understanding of causal attributions of dementia that practitioners need to understand to provide culturally competent practice and highlights a need to customize public education messages by specific ethnic groups.

A Methodology for More Efficient Tail Area Sampling with Discrete Probability Distributions

Monte Carlo Method is commonly used to observe the overall distribution and to determine the lower or upper bound value in statistical approach when direct analytical calculation is unavailable. However, this method would not be efficient if the tail area of a distribution is concerned. A new method, entitled Two-Step Tail Area Sampling, is developed, which uses the assumption of discrete probability distribution and samples only the tail area without distorting the overall distribution. This method uses a two-step sampling procedure. First, sampling at points separated by large intervals is done and second, sampling at points separated by small intervals is done with some check points determined at first-step sampling. Comparison with Monte Carlo Method shows that the results obtained from the new method converge to analytic value faster than Monte Carlo Method if the numbers of calculation of both methods are the same. This new method is applied to DNBR (Departure from Nucleate Boiling Ratio) prediction problem in design of the pressurized light water nuclear reactor.     

Order test for high-dimensional two-sample means

We propose a new method to test the order between two high-dimensional mean curves. The new statistic extends the approach of Follmann (1996) to high-dimensional data by adapting the strategy of Bai and Saranadasa (1996). The proposed procedure is an alternative to the non-negative basis matrix factorization (NBMF) based test of Lee et al. (2008) for the same hypothesis, but it is much easier to implement. We derive the asymptotic mean and variance of the proposed test statistic under the null hypothesis of equal mean curves. Based on theoretical results, we put forward a permutation procedure to approximate the null distribution of the new test statistic. We compare the power of the proposed test with that of the NBMF-based test via simulations. We illustrate the approach by an application to tidal volume traces.     

中西部地区新型城镇化及其推进:湖南个案

中西部地区新型城镇化是我国推进新型城镇化战略的重点和难点。浏阳经济技术开发区在推进新型工业化过程中,实施了低成本战略,以"绝对成本优势"确定产业定位,以"比较成本优势"招商引资,以"低风险成本"助推产业扩张。在推进城镇化时,浏阳经济技术开发区从降低交易成本切入,亦实施了低成本战略。浏阳经济技术开发区的城镇化路径,为中西部地区城镇化提供了如下启示:城镇化发展要以工业化为依托、不可盲目造城;工业化发展必须因地制宜、立足本地优势;推动城镇化政府要有所作为,更要发挥市场决定性作用。

Factors associated with the preventive healthcare service use among older adults in Korea: Focusing on age variation

The importance of preventive health examinations for older adults has been well emphasized due to an increase in chronic diseases associated with age. In this study, we estimated the preventive health examination participation rate and its associated factors among the elderly with specific focuses on the moderating effects between age and socioeconomic status. We used data drawn from the first to sixth waves (4164 people) of the Korean Longitudinal Study of Aging for the elderly aged 65 and over. A generalized linear model was used to address research questions. The results showed that the participation rate decreased as older adults age. The interaction between age and education was also significant, indicating that older adults with higher education were more likely to use a preventive health examination compared to those with lower education. There were no significant interaction effects between income and age. Based on the findings, implications for theory and practice were discussed with specific focuses on age‐specific approaches in preventive healthcare services for older adults.

Production quantity allocation for order fulfilment in the supply chain: a neural network based approach

In the current global business environment, it is very important to know how to allocate products from the producer to buyers (or distributors). If products are not appropriately distributed due to absence of an effective allocation policy, the producer and buyers cannot expect to increase customer satisfaction and financial profit. Sometimes some buyers can order more than the actual demand due to inappropriately forecasting customer orders. This is the big obstacle to the effective allocation of products. If the producer can become aware of buyers’ actual demands, it is possible to realise high-level order fulfilment through the effective allocation of products. In this study, new allocation policies are proposed considering buyers’ demands. The back propagation algorithm, one of the learning algorithms in neural network theory, is used to recognise actual demands from the previous buyers’ orders. After excluding surplus demands included in buyers’ demands, products are allocated to buyers according to one of the existing allocation policies depending on the company's decision. In the numerical examples, new allocation policies reducing buyers’ surplus demands outperform previous allocation policies with respect to average amount of backorder.     

How to Make a Newcomer Happy? The Mediating Role of Career Commitment on the Relationship Between Unmet Expectations and Job Satisfaction

This study focuses on the relationships of unmet expectations to occupational commitment and job satisfaction. The direct and indirect (via occupational commitment) effects of unmet expectations on job satisfaction were investigated in 397 new Chinese employees. For this purpose, structural equation modeling and bootstrap method was used, and fit indices and Chi square values were compared between partially-mediated and fully-mediated models. Results confirmed the ubiquity of unmet expectations in newcomers, and confirmatory factor analysis verified its latent structure including unmet prestige, unmet health, and unmet progress. Structural equation modeling and Chi square test indicated the partial mediation of occupational commitment on the relationship between unmet expectations and job satisfaction. Testing the mediating effects using the bootstrap method also revealed a significant path from unmet expectations to job satisfaction through occupational commitment. Findings extended those of prior studies and shed light on the protection of occupational commitment to job satisfaction; these findings provide enlightenment on promoting job satisfaction for new employees in their first few days.
