Does online ticket booking system make people better off? An empirical study on railway service

The Spring Festival Travel Rush (SFTR) as the largest annual migration on earth has been a serious challenge for the railway system in China. In order to reduce the difficulty of ticket purchase, Chinese government has adopted information and communications technology (ICT) include online ticket booking system so that more ticket channels are available for passengers to choose from. However, whether the online ticket booking system in transportation can improve passengers’ well-being with the Spring Festival experience remains unknown. In this study, a structural equation model is developed to investigate the impact of online ticket booking system, socioeconomic status and perceived control on passengers’ well-being during SFTR. Results show that online ticket booking system has a direct positive influence on passengers’ well-being. In addition, the application of online ticket booking system and perceived control play an important mediating role between socioeconomic status and passengers’ well-being of Spring Festival. In particular, online ticket booking system had made it easier for people of lower socioeconomic status to purchase tickets and thus significantly raised their well-being.     

School and individual factors on game addiction: A multilevel analysis

This study investigated the protective or risk factors of game addiction at individual and school-level using multilevel modelling. Data from Korea Children and Youth Panel Survey was used for the analyses. The findings revealed that individual-level variables, including gender, delinquency, family intimacy, stress, self-esteem and self-control, were significant predictors of game addiction. Furthermore, protective school climate contributed to decreasing the level of game addiction and risky school climates positively predicted game addiction. The effect of individual-level variables on game addiction was different depending on the type or level of school-level variables. Based on the findings, implications and suggestions for future studies were discussed.     

Motivational dynamics in the development of career attitudes among adolescents

Super (1990) proposed that the psychological determinants of career development attitudes are time perspective, self-esteem, and causal attributions. The present study analyzed the effects of these determinants on the career development attitudes of 320 students from grade 9 and 300 students from grade 12. The analysis of the data using structural equations modeling (LISREL) showed both similarities and differences in the effects of the determinants of career attitudes between the two grade levels. The results are discussed in the context of the career maturity model.     

On growth curves and mixture models

The multilevel model of change and the latent growth model are flexible means to describe all sorts of population heterogeneity with respect to growth and development, including the presence of sub‐populations. The growth mixture model is a natural extension of these models. It comes at hand when information about sub‐populations is missing and researchers nevertheless want to retrieve developmental trajectories from sub‐populations. We argue that researchers have to make rather strong assumptions about the sub‐populations or latent trajectory classes in order to retrieve existing population differences. A simulated example is discussed, showing that a sample of repeated measures drawn from two sub‐populations easily leads to the mistaken inference of three sub‐populations, when assumptions are not met. The merits of methodological advises on this issue are discussed. It is concluded that growth mixture models should be used with understanding, and offer no free way to growth patterns in unknown sub‐populations. Copyright © 2006 John Wiley & Sons, Ltd.     

An investigation into the relationship between the reported experience of negative life events,trait stress-sensitivity and false confessions among further education students in Iceland

This study investigates the interplay between the reported experiences of negative life events, reported levels of nerves, fear and tension experienced over the past 30 days, and reported false confessions. Data were obtained from 11,388 students in further education in Iceland, out of which 5439 participants were male and 5837 were female. Single level, random intercept, structural equation models were fitted showing that latent stress-sensitivity, indicated by levels of nerves, tension, fear, and the number of negative life events experienced exerted a significant direct effect on the likelihood of false confessions. Stress-sensitive interviewees (those reporting high levels of nerves, fear, tension and negative events) may be more susceptible to environmental influences, due to heightened physiological responsiveness towards and a negative perception of situations and social encounters, with false confessions being a direct consequence of this. A suggestion from the findings is that the type of false confession (the reason for it) may possibly dependent upon which contextual trigger has influenced the interviewee the most – those within the police interview itself and/or pressures from the wider environment within which they reside.     

Phase-field simulations of the interaction between a grain boundary and an evolving second-phase particle

We performed phase-field simulations to analyse the interaction of a migrating grain boundary with an evolving second-phase particle. It is found that depending on the difference between the interfacial energies of the particle–matrix interface for the two grain orientations involved and the driving force for grain boundary movement, particles with a particle size well above the critical limit can dissolve due to passage of the boundary.     

Strength contributions from precipitates

A theory for the strength contribution from precipitates is developed based on the statistical particle-size and shape distributions and the corresponding obstacle strengths. The generic case of spherical precipitates and the special case of needle-shaped precipitates in the 6xxx aluminium alloy series are considered. It is accounted for that the largest precipitates are stronger and at the same time, intersect a larger number of slip planes than the smaller ones. For a considered peak aged AA6082, the improved model gives a 59% higher strength, which fits the experiments well without the need of previously introduced calibration parameter for the mean effective particle spacing in the slip plane.     

Further evidence for a bifactor solution for the Consideration of Future Consequences Scale: Measurement and conceptual implications

The Consideration of Future Consequences construct has been found to relate meaningfully to several positive outcomes in temporal research. Researchers have proposed 1-factor, 2-factor, and bifactor solutions to the Consideration of Future Consequences Scale (CFCS). Using 313 British University undergraduates, we tested four competing models: (a) a 12-item unidimensional model, (b) a model fitted for two uncorrelated factors (CFC-Immediate and CFC-Future), (c) a model fitted for two correlated factors (CFC-I and CFC-F), and (d) a bifactor model. Results supported the bifactor model, suggesting that the two hypothesized factors are better understood as grouping factors. Accordingly, the present study supports the CFCS as a unidimensional global future orientation measure. These results have important implications for the study of future orientation using the CFCS. Researchers using the CFCS are encouraged to examine a bifactor solution for the scores.
