Multiple lo...

Microlearning has been predicted as a promising learning trend to cope with the rapidly changing world. The technology-mediated short form of learning also received language partitioners’ and researchers’ interest in adopting microlearning in language education. Notably, most existing studies focused on vocabulary or structural learning instead of...

Two studies were conducted to investigate the career decision status (CDS) of culturally Chinese people in Taiwan (henceforth referred to as Taiwanese CDS [TCDS]). The first study established a conceptual framework for measuring TCDS. Using a qualitative design, we collected and conceptualised the self-reported CDS of 289 participants, who were sub...

ABSTRACT Research is sparse on who targets whom in peer aggression. In this study, we investigated the harm associated with the type of relationship between aggressed and aggressor with an international sample of over 5,000 students aged 11–16, living in 12 nations. Best friends and individuals with whom the respondent had no relationship were the...

The relationship between victims and perpetrators has been under-researched. In this study we examined this relationship among a diverse sample of 405 Taiwanese adolescents aged 11 to 16. Our findings revealed that most students’ participation in peer aggression was harmless banter between best friends, friends, and classmates. Approximately 75% of...

We examined flight attendants’ career satisfaction and addressed how career stress affects the relationship between personality and career satisfaction. After conducting a focus group interview with 6 flight attendants and 3 senior flight attendants and a pilot study with 122 employees of a large airline corporation in Taiwan to develop the Career...

While the poor psychosocial outcomes of young people who have experienced bullying are well known, the harm associated with experiences that do not meet the bullying criteria is not well understood. The aim of this study was to examine the level of harm associated with experiences of peer aggression, as well as bullying, by directly measuring the f...

The indigenous Austronesian minority of Taiwan is heavily affected by health disparities which may include suffering from a greater burden of the tobacco epidemic. While a lack of representative data has historically precluded an investigation of the differences in smoking between Taiwanese ethnicities, these data have recently become available thr...

The use of Structural Equation Modeling (SEM) in research has increased in psychology, sociology, education, and economics since it was first conceived by Wright (1918), a biometrician who was credited with the development of path analysis to analyze genetic theory in biology (Teo & Khine, 2009). In the 1970s, SEM enjoyed a renaissance, particularl...

This study proposes the learning vector quantization estimated stratum weight (LVQ-ESW) method to interpolate missing group membership and weights in identifying the accuracy of measurement invariance (MI) in a stratified sampling survey. Survey data is rife with missing information, such as gender and race, which is critical for identifying MI, an...

The goal of this study is to explore the factor effect of learning vector quantization. The manipulated factors are training pattern, learning rate, types of mixed data, and hidden node. The results showed that the average accuracy for severe overlap data was significantly lower than for those of slight and moderate overlap data. The worst classifi...

BACKGROUND: The prevalence of physical inactivity among housewives is high, yet little research has assessed their usual physical activity. OBJECTIVES: To develop a scale to assess the risk of physical inactivity and strength of association with clinical correlates of the Chinese short version of the International Physical Activity Questionnaire (I...

The aim of this study is to provide latent variable models (LVM) to evaluate interaction effects between functional brain cortical regions. Rapidly developed imaging techniques and methods, for instance, ERP and fMRI, can serve as feasible accessories on mapping brain functions by monitoring activities among different cortical regions. Without capa...

As a result of the severe acute respiratory syndrome (SARS) pandemic, the World Health Organization placed Taiwan on the travel alert list from May 21 to July 5, 2003. The aim of this study was to explore the post-crisis psychological distress among residents in Taiwan after the SARS epidemic. The target population consisted of a nationwide represe...

A supervised learning vector quantization (LVQ) method is proposed in this paper to project stratified random samples to infer hierarchical neural networks. Comparing with two traditional methods, i.e., list-wise deletion (LWD), and non-amplified (NA), the supervised LVQ shows satisfying efficiencies and accuracies in simulation studies. The accomp...

Background/PurposeThis study was designed to examine how psychological factors related to premenstrual syndrome (PMS) influence adherence to medical regimens for patients with breast pain.

Background: A rare disease is generally considered to have a prevalence of less than one affected individual per 10,000 populations as well as identified in the rare disease list or announced by the Department of Health. Relatively few studies have been conducted concerning rare disease in Taiwan. Objective: To identify the special health care ne...

This study implements a scale purification procedure onto the standard MIMIC method for differential item functioning (DIF) detection and assesses its performance through a series of simulations. It is found that the MIMIC method with scale purification (denoted as M-SP) outperforms the standard MIMIC method (denoted as M-ST) in controlling false-p...

Ecological-inference-based statistical methods employ aggregated (ecological) data to approximately infer individual-level structures of interests when individual-level data were not available. Under the same conceptual frames, we introduce the ecological-inference-based latent growth model (EI-LGM) to analyze cross-years latent trends of a general...

The multiple indicators multiple causes (MIMIC) latent class analysis (LCA) model is an excellent classification method when researchers cannot find a "gold standard" to classify participants. The MIMIC-LCA model includes features of a typical LCA model and also introduces a new relation between the latent class and covariates. In other words, a lo...

This paper proposes growth mixture modeling to assess intervention effects in longitudinal randomized trials. Growth mixture modeling represents unobserved heterogeneity among the subjects using a finite-mixture random effects model. The methodology allows one to examine the impact of an intervention on subgroups characterized by different types of...

A longitudinal study was carried out to study various growth patterns in the early learning of the Chinese language. We investigate different developmental trajectories during early learning stages of Chinese linguistic abilities. Cognitive development of Chinese reading process, i.e., phonemic/tonic awareness and word recognition can be thus revea...

Finite mixture multivariate generalized linear modeling has been shown to be an important analytic tool for many research fields, for example, image recognition, astronomical data classification, biomedicine diagnosis, and biological classification. Recent statistical and computational advances have further encouraged researchers to explore the mod...

Recent statistical advances, for example, Bandeen-Roche, Miglioretti, Zeger and Rathouz (1997); Jedidi, Jagpal and DeSarbo (1997); and Wang and Puterman (1998) have made it feasible to fit finite mixture models in a wide range of applications. With a collection of plausible models for a given data set, problems of model selection arise. Selection a...
