The effect of the leadership style of the secondary school principal on student achievement in select public schools in Louisiana was examined in this study. The null hypothesis was that there was no statistically significant difference between principal leadership style and student academic achievement. The researcher submitted the LEAD-Self…

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. This…

Purpose of the Study: The present study examined the characteristics of health disparities grants funded by National Institute on Aging (NIA) from 2000 to 2010. Objectives were (a) to examine longitudinal trends in health disparities-related grants funded by NIA and (b) to identify moderators of these trends. Design and Methods: Our primary data…

Primary literature is essential for scientific communication and is commonly utilized in undergraduate biology education. Despite this, there is often little time spent "training" our students how to critically analyze a paper. To address this, we introduced a primary literature module in multiple upper-division laboratory courses. In…

This study had a three-fold purpose: first, to assess the attitudes of student affairs administrators working in the Florida College System (FCS) about globalization, internationalization, and their strategies for effecting internationalization efforts at their community/state colleges. This study also investigated the relationship between student…

In multilevel modeling, group-level variables (L2) for assessing contextual effects are frequently generated by aggregating variables from a lower level (L1). A major problem of contextual analyses in the social sciences is that there is no error-free measurement of constructs. In the present article, 2 types of error occurring in multilevel data…

Race group differences in suicide death classification in a sample of 109 Black and White university students were examined. Participants were randomly assigned to read three vignettes for which the vignette subjects' race (only) varied. The vignettes each described a circumstance (terminal illness, academic failure, or relationship difficulties)…

Group differences in resting state functional magnetic resonance imaging connectivity between individuals with autism and typically developing controls have been widely replicated for a small number of discrete brain regions, yet the whole-brain distribution of connectivity abnormalities in autism is not well characterized. It is also unclear…

Publication patterns of articles in "Adultspan" from 1999 to 2009 were reviewed. Author characteristics and article content were analyzed to determine trends over time. Research articles were analyzed specifically for type of research design, classification, sampling method, types of participants, sample size, types of statistics used, and…

Several psychophysical and neuropsychological investigations have suggested that the mental representation of numbers takes the form of a number line along which magnitude is positioned in ascending order according to our reading habits. A longstanding debate is whether this spatial frame is triggered automatically as intrinsic part of the number…

Although the relationship between students' perceptions of quality of teaching and student satisfaction may seem self-evident, the interaction between these concepts and related methods of assessment is rarely examined. The findings reveal that the perceived teaching quality categorization emerges as a concept with multiple facets centered on…

Despite a continuing record of interest over the years, few studies have documented the demographics of grade retention or the relationship between it and academic achievement across multiple grades and groups of students. In this research, we were interested in the characteristics and consequences of retaining students in elementary (K-5) and…

This case study analyzes how and why student engagement differs across 581 classes in one diverse high school. Factor analyses of surveys with 1,132 students suggest three types of engaging teaching practices--connective instruction, academic rigor, and lively teaching. Multilevel regression analyses reveal that connective instruction predicts…

Background: Recent models of the early emergence of autism spectrum disorder (ASD) propose that infant intrinsic risk susceptibilities in behaviour may be amplified by interaction within the early social environment into an increasingly atypical developmental trajectory. This study examines whether 6- and 12-month parent-infant interactions in…

This study examined associations between Asian international students' perceived quality of contact with faculty, administrative personnel and other students, and self-reported gains in areas identified in "College Students Experience Questionnaire." The sample included 705 Asian students from 25 research universities across the United…
