Multilevel Dynamic Generalized Structured Component Analysis for Brain Connectivity Analysis in Functional Neuroimaging Data

We extend dynamic generalized structured component analysis (GSCA) to enhance its data-analytic capability in structural equation modeling of multi-subject time series data. Time series data of multiple subjects are typically hierarchically structured, where time points are nested within subjects who are in turn nested within a group. The proposed approach, named multilevel dynamic GSCA, accommodates the nested structure in time series data. Explicitly taking the nested structure into account, the proposed method allows investigating subject-wise variability of the loadings and path coefficients by looking at the variance estimates of the corresponding random effects, as well as fixed loadings between observed and latent variables and fixed path coefficients between latent variables. We demonstrate the effectiveness of the proposed approach by applying the method to the multi-subject functional neuroimaging data for brain connectivity analysis, where time series data-level measurements are nested within subjects.     

An fMRI study of advertising appeals and their relationship to product attractiveness and buying intentions

This study examines the effects of various visual apparel advertisements on consumers' brain activation during exposure to different types of advertising appeals (i.e., celebrity, non‐celebrity, and rational). The influence on consumer perceptions of products and their subsequent buying intentions are also measured. A repeated measures experimental design was employed, and the total of 27 right‐handed female subjects participated in the study. The results of the quantitative data showed significant differences in perceived product attractiveness for each of the three types of advertising appeals, but not in buying intentions. Regarding the fMRI results, our findings support the notion that celebrity advertising appeals are associated with heightened brain activation of memory‐related/retrieval regions, reflecting how consumers remember the ad and are influenced by the attractiveness of the source. Non‐celebrity advertising appeals were more closely associated with brain activation of regions thought to mediate self‐reflection and also engaging executive functions. For rational advertising appeals, our findings showed significant activation in brain areas associated with logical evaluative decision making reflecting more logical processing value assessments and reward potential. Therefore, retailers/marketers must be particularly mindful to match the appropriate advertising appeal to the specific purpose of the advertisement. This study also provides brain‐based insight into the effectiveness of different types of advertising appeals and whether or not they have the desired impact on the consumer.

Quality of Jobs for Female Workers: A Comparative Study of South Korea and Australia

This study conducts a comparative analysis regarding the quality of job in Australia and South Korea on the basis of ordered logit model using two countries’ household data sets during 2003–2009. We compose the quality of job into various subgroups by combining hourly wage, job security and working hours, and verify that despite having similar Affirmative Action (AA) systems in the two countries, Australian women are more likely to work in jobs with higher quality compared to South Korean women subject to the loose incentive operation of AA.     

The psychology of ongoing threat: relative risk appraisal, the September 11 attacks, and terrorism-related fears

There are now replicated findings that posttraumatic stress disorder (PTSD) symptoms related to the September 11, 2001, attacks occurred in large numbers of persons who did not fit the traditional definition of exposure to a traumatic event. These data are not explained by traditional epidemiologic "bull's eye" disaster models, which assume the psychological effects are narrowly, geographically circumscribed, or by existing models of PTSD onset. In this article, the authors develop a researchable model to explain these and other terrorism-related phenomena by synthesizing research and concepts from the cognitive science, risk appraisal, traumatic stress, and anxiety disorders literatures. They propose the new term relative risk appraisal to capture the psychological function that is the missing link between the event and subjective response in these and other terrorism-related studies to date. Relative risk appraisal highlights the core notion from cognitive science that human perception is an active, multidimensional process, such that for unpredictable societal threats, proximity to the event is only one of several factors that influence behavioral responses. Addressing distortions in relative risk appraisal effectively could reduce individual and societal vulnerability to a wide range of adverse economic and ethnopolitical consequences to terrorist attacks. The authors present ways in which these concepts and related techniques can be helpful in treating persons with September 11- or terrorism-related distress or psychopathology.

无边界职业生涯取向与青年员工职业成功：职业胜任力的中介作用

基于职业成功的胜任力模型,探讨无边界职业生涯取向与青年员工职业成功的关系。采用两阶段（two-wave）问卷调查法,以385名35岁以下的年轻员工为样本进行研究。结果表明,无边界思维模式与青年员工的主观职业成功、客观职业成功均显著地正相关,职业胜任力在其中起完全中介作用;组织流动性偏好与青年员工的主观职业成功、客观职业成功均显著地负相关,职业胜任力在其中起中介作用。研究证实了无边界职业生涯取向对青年员工职业成功的“双刃剑”效应,为青年员工的职业生涯管理提供了重要启示。     

Sacred Canopies or Religious Markets? The Effect of County-Level Religious Diversity on Later Changes in Religious Involvement

Secularization theories, such as Berger's Sacred Canopy argument, hold that religious diversity leads to a decline in religious participation. Religious market models (e.g., Finke and Stark) argue the opposite. Voas, Olson, and Crockett found that nearly all of the vast research exploring this important question prior to 2002 was flawed due to a previously unrecognized noncausal statistical relationship between measures of religious diversity and measures of religious participation. Since 2002, this methodological issue has largely stymied research on this important topic. We first describe how, following Voas et al.’s recommendations, longitudinal models can overcome these problems. We then apply these methods to data measuring the religious composition of all U.S. counties found in the Religious Congregations and Membership Studies from 1980, 1990, 2000, and 2010. Using multilevel longitudinal regression models, we find that greater county-level religious diversity is followed by later declines in county-level religious participation rates. The negative effect size of religious diversity is large and robust to changes in the control variables and different methods of measuring religious diversity.     

ACACIA: an agent-based program for simulating behavior to reach long-term goals

We present ACACIA, an agent-based program implemented in Java StarLogo 2.0 that simulates a two-dimensional microworld populated by agents, obstacles and goals. Our program simulates how agents can reach long-term goals by following sensorial-motor couplings (SMCs) that control how the agents interact with their environment and other agents through a process of local categorization. Thus, while acting in accordance with this set of SMCs, the agents reach their goals through the emergence of global behaviors. This agent-based simulation program would allow us to understand some psychological processes such as planning behavior from the point of view that the complexity of these processes is the result of agent–environment interaction.
