Bumble bees are valuable pollinators of native and cultivated flora. Despite our knowledge of bumble bee nest site selection, most efforts to attract bumble bees to artificial domiciles have been met with limited success. Creating and evaluating artificial domiciles provides students an opportunity to investigate a real problem. In this lesson,…

We argue that the global digital divide, as measured by cross-national differences in Internet use, is the result of the economic, regulatory and sociopolitical characteristics of countries and their evolution over time. We predict Internet use to increase with world-system status, privatization and competition in the telecommunications sector,…

Videoconferencing (VC) technology has been used successfully to provide psychiatric services to patients in rural and otherwise underserved settings. VC-based diagnostic interviewing has shown good agreement with conventional face-to-face diagnosis of dementia in several investigations, but extension of this technology to neurocognitive assessment…

Alcohol's psychological, cognitive, and motor effects contribute to rape. Based on theory and past research, we hypothesized that there would be a curvilinear relationship between the quantity of alcohol consumed by perpetrators and how aggressively they behaved. Moderate levels of intoxication encourage aggressiveness; however, extreme levels…

Intergroup attitudes were assessed in European-American first grade (M=6.8 years) and fourth grade (M=9.9 years) boys and girls (N=94) to test hypotheses about implicit racial biases, perceptions of similarity between peer dyads, and judgments about cross-race friendships. Two assessments, an ambiguous situations task and a perceptions of…

This study set out to investigate the self-teaching of good and poor readers in pointed Hebrew--a highly regular orthography. Four groups of children (three groups in Grades 4 to 6, and one group in Grade 2) were included in this study; poor readers with large discrepancies between IQ and reading ("dyslexics"), IQ-nondiscrepant poor…

Often quantitative data in the social sciences have only ordinal justification. Problems of interpretation can arise when least squares multiple regression (LSMR) is used with ordinal data. Two ordinal alternatives are discussed, dominance-based ordinal multiple regression (DOMR) and proportional odds multiple regression. The Q[superscript 2]…

We report on a study of the relationship between calculator technology and student learning in two introductory statistics class sections taught by the same instructor at the University of Texas at San Antonio. At the introduction of hypothesis testing and confidence intervals, one class section (A) was given graphing calculators capable of…

The outcome results of home visiting programs have been mixed and modestly encouraging at best. To further understand this phenomenon it is important to understand what influences participation in home visiting programs. This study explores the relationship between housing stability and level of participation in an Early Head Start home visiting…

Students and parents base college selection on how well the college will overcome the perceived financial, social, psychological, physical, and functional risks associated with the college experience. Nineteen criteria associated with these risks were evaluated for significant differences between students and parents as well as for their level of…

Introduction: This research addresses preschoolers' intuitive understanding of rectilinear movement and some variables which affect it, and the type of arguments used when related knowledge states are justified. A first working hypothesis is that the resolution of practical, functional situations would be based on self-regulation processes. A…

In hypothetical scenarios involving two groups (nations or groups of workers), subjects voted on three proposals: one helped group A (their group), one helped B, and one helped both groups, more than the average of the first two but less than their maximum. When subjects voted for one proposal, most voted for the one that helped group A. This…

Teaching practicum requires a philosophy to give directions to values and actions. The philosophy proposed here aims for the development of a reflective and reflexive learner who learns through situational analyzing, theorizing, hypothesis testing, inquiring, experimenting, and justifying. Such development has to be built around the searching and…

Attitudinal data tested hypotheses that students have more positive attitudes toward science when teachers regularly emphasize hands-on laboratory activities and when students more frequently experience higher levels of experimentation or inquiry. The first predicted that students would have more positive attitudes toward science in classrooms…

Nicotine replacement therapy (NRT) repeatedly has been shown to improve smoking treatment outcome. The major mechanism posited for this improvement in outcome is that NRT reduces nicotine craving and withdrawal. The authors tested this hypothesized mechanism of action using real-time data on craving and withdrawal, collected by ecological…
