Several concerted movements toward mathematical modeling have been seen in the last decade, reflecting the growing global relationship between the role of mathematics in the context of modern science, technology and real life. The literature has mainly covered the theoretical basis of research questions in mathematical modeling and the use of…

The Multidimensional Personality Questionnaire (MPQ) measures a wide range of personality traits associated with affect and temperament. However, the lengthy administration time may have hindered its widespread use in personality research. The National Survey of Midlife Development in the United States (MIDUS) has adapted a short version of the…

Earlier studies established the role of demographic and temperamental features (DTFs) in the adaptation of childhood stuttering. However, these studies have been short on examining the latent interrelationships among DTFs and not utilizing them in predicting this disorder. This research article endeavors to examine latent interrelationships among…

There is good evidence for an association between poor reading and anxiety, but the mechanisms responsible for this association are currently unknown. In this study, we used structural equation modeling of four large longitudinal databases from the United Kingdom (n = 7,870), the United States (ns = 8,001 and 7,160), and Australia (n = 768) to…

"Grit" is defined as passion and perseverance for achieving long-term goals and consists of two proposed subcomponents: consistency of interests and perseverance of effort. It has become a much-discussed construct even though research on its underlying factor structure has produced inconclusive results. Furthermore, grit as measured by…

Purpose: This study aims to empirically validate an innovative work behaviour-enhancing model of employability in small- and medium-sized enterprises (SMEs), and to examine possible moderating effects of age. Design/methodology/approach: Data have been collected from 487 pairs of employees and their immediate supervisors who worked in 151 SMEs.…

This paper highlights the importance of conducting studies to ascertain students' perceptions of the teaching-learning process, as this information can provide a valuable guide to course planning and enhance teaching. This study analyses, based on structural equation modelling, the relationship between students' academic performance in an…

Today, it is necessary to learn to manage and administer organizations based on values, which is also influenced by the culture and atmosphere of the organization. No comprehensive research has been done on organizational culture and personnel values. Therefore, the purpose of this study is to provide a theoretical framework based on the…

We present three statistical methods for causal analysis in life course research that are able to take into account the order of events and their possible causal relationship: a cross-lagged model, a latent growth model (LGM), and a synthesis of the two, an autoregressive latent trajectories model (ALT). We apply them to a highly relevant…

The purpose of this study was to determine what variables predict the use of instructional technology among community college instructors. Legislators, community college administrators, and students expect innovative lessons from instructors that use technology. This study addresses the problem of not knowing what predicts instructional technology…

This paper presents the results of a study that explored undergraduate students' perceptions of cognitive, social, and teaching presences in online business courses and their relationship to students' course satisfaction in addition to demographic variables. Student engagement has proven to be one of the main reasons for student retention and…

Despite recognition that youth civic engagement is multidimensional, different modeling approaches are rarely compared or tested for measurement invariance. Using a diverse sample of 2,467 elementary, middle, and high school-aged youth, we measured eight dimensions of civic engagement: social responsibility values, informal helping, political…

Although research suggests an interplay between identity development and self-esteem, most studies focused on the role of identity commitment and measured only level of self-esteem. This study examined longitudinal associations between Berzonsky's (2011) styles of identity exploration and two distinct features of self-esteem: level of self-esteem…

Bilingualism appears to be related to poor language and reading comprehension in the instructional language (L2). However, in the long term, an early age of second language acquisition (AoA) may produce higher levels of second language skills than a later onset of L2 exposure. Most studies on school-aged second language learners (L2 learners)…

This study focuses on the evaluation of academic conferences and ways of improving them. The study includes a case study of one university in Israel. Sixty two academic faculty members from varied departments completed a questionnaire, including 61.7% women and 38.3% men. The research participants were asked a single open question: "What do…
