This study examined whether counting and rapid automatized naming (RAN) could operate as significant predictors of both later arithmetic calculation and reading fluency. The authors also took an important step to clarify the cognitive mechanisms underlying these predictive relationships by controlling for the effect of phonological awareness and…

Data security breaches are categorized as loss of information that is entrusted in an organization by its customers, partners, shareholders, and stakeholders. Data breaches are significant risk factors for companies that store, process, and transmit sensitive personal information. Sensitive information is defined as confidential or proprietary…

Transformational leadership has been shown to affect organizational commitment, capacity development, and performance. However, these relationships have received very little attention in schools, especially high schools in the United States that are experiencing educational reform initiatives under No Child Left Behind. Using a sample of 1403 high…

This dissertation is composed of four stand-alone yet linked chapters. Chapter 1 provides an overview of the theoretical underpinnings of the constructs of adaptive behavior and support needs and their evolution throughout history. There is also a review of the limited literature available examining the relationship between the two constructs that…

The present study aims to examine the mediating effects of achievement emotions between action control and learning strategies. Two hundreds and twenty-six undergraduates (125 males and 101 females) participated to complete a questionnaire consisting of three scales. To analyze the data, path analyses and structural equation modeling were used.…

This study examined reliability and validity of the Devereux Early Childhood Assessment (DECA), based on samples of parents and teachers' ratings of 1,145 entering kindergartners in the Southwest. Confirmatory factor analysis showed that DECA presented good reliability and validity for manifest variables, corroborating previous findings. Three…

Drawing on data from a three-wave longitudinal study, the present research examined predictors of young adults' intentions to participate in politics and their actual political activities while referring to the broader assumptions of the theory of planned behavior. The analyses were based on a sample of university students from the federal state…

Traditional methods of assessing construct stability are reviewed and longitudinal mean and covariance structures (LMACS) analysis, a modern approach, is didactically illustrated using psychological entitlement data. Measurement invariance and latent variable stability results are interpreted, emphasizing substantive implications for educators and…

Few studies in medical education have studied effect of quality of motivation on performance. Self-Determination Theory based on quality of motivation differentiates between Autonomous Motivation (AM) that originates within an individual and Controlled Motivation (CM) that originates from external sources. To determine whether Relative Autonomous…

Globalization brings change in all aspect of human life, including in how job and organizations operate. These changes create strain and stress not only among employee at business organization, but also among academic staff. The dean of faculty or department at university has important role in prevent the effects of job stress among the academic…

Social, economic, violence, political, and gun access predictors of suicide and gun suicide were examined via sociological autopsy. The model predicting suicide rates overall had the best results, X[superscript 2](9, N = 50) = 5.279 (CMIN, the goodness of fit statistic that represents the minimum discrepancy between the unrestricted sample…

In addition to evaluating a structural equation model (SEM) as a whole, often the model parameters are of interest and confidence intervals for those parameters are formed. Given a model with a good overall fit, it is entirely possible for the targeted effects of interest to have very wide confidence intervals, thus giving little information about…

Working memory is crucial for many higher-level cognitive functions, ranging from mental arithmetic to reasoning and problem solving. Likewise, the ability to learn and categorize novel concepts forms an indispensable part of human cognition. However, very little is known about the relationship between working memory and categorization, and…

Empowerment theory provides both a value orientation for community-based research and practice, and a conceptual framework for understanding and evaluating interventions. One critical question in empowerment theory involves whether a reciprocal (bidirectional) relationship exists between community participation (CP) and psychological empowerment…

This study examined the working mechanisms of social support for victims of bullying. Structural equation modeling analyses based on retrospective survey data (N = 448) revealed that the effects of supportive messages varied distinctively, depending on the content of the messages; emotional and esteem support enhanced, but network support impeded,…
