When fit indices and residuals are incompatible

Standard chi-square-based fit indices for factor analysis and related models have a little known property: They are more sensitive to misfit when unique variances are small than when they are large. Consequently, very small correlation residuals indicating excellent fit can be accompanied by indications of bad fit by the fit indices when unique variances are small. An empirical example of this incompatibility between residuals and fit indices is provided. For illustrative purposes, an artificial example is provided that yields exactly the same correlation residuals as the empirical example but has larger unique variances. For this example, the fit indices indicate excellent fit. A theoretical explanation for this phenomenon is provided using relationships between unique variances and eigenvalues of the fitted correlation matrix.     

Exploring the Ethical Aspects of Leadership: From a Korean Perspective

Theories of ethical leadership provide important insights about the effect of leader’s ethics on the relationship between leaders and followers. However, there is an increasing demand for addressing key constructs that enhance the capacity to explain theoretical aspects of ethical leadership. The purpose of this study is to expand the theoretical framework of ethical leadership based on Korean traditional leadership by focusing on personal cultivation, morality, and social responsibility. Using a framework of intrapersonal process as leadership and core value and competence as components of leadership, this study examines the ethical aspects of Korean traditional leadership and provides the implications to further develop the theory of ethical leadership. It is found that ethical integrity ensued from sugi (self-cultivation) is an essential precondition to develop leadership, and the core value of ethical leadership includes Zhixin-Chijing (cultivation of the mind and internal piety) and the competence consists of both Ipzhi (setting a solid self-vision/establishing goal) and Silsim (practical mind, grasp changes in reality with a sound mind) in Korean traditional leadership that contributes to expanding the theoretical understanding of ethical leadership. Implications for future research in the area of ethical leadership are discussed.     

On the AlN precipitation and grain refinement in the Al(N)-added medium C–Mn steels

The precipitation of AlN particles and grain refinement in the Al(N)-added medium C–Mn steel have been studied using a Gleeble hot-deformation simulator and extraction replica TEM technique. No significant grain refinement occurs during either hot-rolling or hot-deformation/isothermal-holding, which is due to the absence of AlN precipitation; the lack of precipitation is caused by an unusually high-energy barrier for nucleation. Abrupt grain refinement occurs on reheating because of the copious precipitation of AlN during reheating. The copious precipitation of AlN during reheating is possible because thermally unstable Fe-rich sulphides act as precursors for AlN precipitation during reheating.     

Attitudes Toward Date Rape Among University Students in South Korea

The purpose of this study is to examine attitudes toward date rape among university students in South Korea. Participants included 163 students recruited from two universities in South Korea. Results show that male students were less rejecting of date rape-tolerant attitudes than female students were. Also, male students were less rejecting of the belief that the use of force to have sex on a date is acceptable under certain conditions. Attending a sexual assault educational program was associated with more rejection of date rape-tolerant attitudes among females, but not among males. The results will be of particular value to advocates who provide rape prevention and victim intervention programs.     

Board Certification in Psychology: Insights from Medicine and Hospital Psychology

For physicians board certification is an accepted tradition that research suggests improves services and outcomes. In contrast, relatively few psychologists pursue board certification suggesting ambivalence or limited contingencies reinforcing it. The authors report on medical school and hospital-based psychologists’ attitudes toward board certification and current certification status. About one-fifth (21.7%) of the sample were certified by the American Board of Professional Psychology, a greater proportion than psychologists generally: Highest rates were seen in neuropsychology (7.5%), clinical psychology (6.4%), clinical child and adolescent psychology (3.2%) and clinical health psychology (2.8%). Few (<2%) reported their hospitals required board certification. Half recognized benefits to the profession for psychologists pursuing board certification, yet 70% opposed requiring it for their hospital-based practice. Forces seeking to promote healthcare quality ultimately may increase expectations for board certification. If consumers, employers, hospitals and managed care organizations demand board certification for health professionals, greater numbers of psychologists would likely seek it.     

Developmental Changes in Visual and Auditory Inhibition in Early Childhood

The development of executive functions in the preschool years is not fully understood. Although there exists a large body of research investigating the maturation of executive functioning in school‐aged children, little is known about the emergence of such skills, in particular inhibition, among preschool‐aged children. Understanding developmental changes of inhibition proficiencies and deficiencies early in childhood is important for charting typical and atypical developmental trajectories. Using an adapted computerized paradigm, the present study examined age‐related changes in visual and auditory inhibition in 68 typically developing children aged 3 to 6 years. The results indicated that although similar age‐related gains in performance occurred across both visual and auditory inhibition tasks, certain modality‐specific differences emerged in terms of accuracy and reaction time. These results suggest that the newly adapted measures used are sensitive enough to capture developmental variations in inhibition. Copyright © 2012 John Wiley & Sons, Ltd.     

Emotion Regulation: The Interplay of Culture and Genes

Given the mounting empirical evidence to support both the cultural and biological shaping of emotional processes, there is a clear need to integrate these determinants of emotional processes. Much in the same vein as these efforts, in our research on gene‐culture interactions, we have examined how cultural and biological factors jointly influence emotion regulation. The present paper specifically aims to present research considering both cultural and genetic factors as two interacting influences that shape emotion regulation. A series of studies conducted to test the gene‐culture interaction involving OXTR rs53576 consistently show that individuals with the variant that is associated with socio‐emotional sensitivity tend to utilize culturally normative forms of emotion regulation more than those without it. These findings underscore the importance of considering the interplay between socio‐cultural and genetic factors that shape social behaviors.     

The Mediating Effects of Motivation for Playing Pokémon Go on Internet Gaming Disorder and Well–Being

This study explored the influence of parenting, middle school students’ temperament, motivation for playing Pokémon Go on Internet Gaming Disorder and well-being. In particular, the mediating effects of motivation for playing Pokémon Go between parenting and Internet Gaming Disorder, as well as between students’ temperament and well-being were also examined. A total of 500 students were selected to participate in an experiment involving Pokémon Go gaming. Students were required to complete scales that measured parenting, temperament, motivation for playing Pokémon Go, well-being, and the IGD-20 test after 6?weeks of game playing.     

Mobile Persuasion: Can Screen Size and Presentation Mode Make a Difference to Trust?

Guided by the Modality, Agency, Interactivity, and Navigability (MAIN) model of technology effects and the heuristic–systematic model (HSM) of information processing, this study explicates underlying mechanisms by which variations in screen size (large vs. small) and presentation mode (video vs. text) contribute to user perceptions of media content on their smartphones. Results from a between‐subjects experiment (N = 120) indicate that large screen size and video mode promote heuristic processing while small screen size and text mode encourage systematic processing. Heuristic processing leads to greater affective and behavioral trust while systematic processing is associated with cognitive trust. Phantom model analysis reveals the effects of large screen size and video mode on purchase intentions are sequentially mediated by type of information processing and multidimensional trust.
