An Exploration of the Sexual Orientation and Educational Outcomes of Undergraduate Fraternity Members

Previous research found an unwelcoming environment may hinder the identity development of college students. Furthermore, studies revealed gay, bisexual, and questioning (GBQ) students may encounter a hostile environment in college fraternities. This influenced the researcher to question if fraternities are as effective in producing educational gains for GBQ members as for heterosexual members. In the present study, the researcher sampled 286 GBQ and 286 heterosexual fraternity members from the aggregate results of the campuses that used the AFA/EBI Fraternity/Sorority Assessment in 2009 or 2010. The researcher conducted rank-based analyses of variance to assess the differences in personal gains, alcohol use, leadership experience, and satisfaction of fraternity members by sexual orientation. Results revealed heterosexual fraternity members reported greater gains as a result of their fraternity experience for the majority of the personal gains measures. There were no differences in alcohol use, leadership experience, and satisfaction of fraternity members by sexual orientation

Education & Crime: A Study in Student Perceptions of Culpability

Criminological research has long been concerned with how stereotypes of offender race and gender affect perceived culpability and policy formation. Using data collected from a college student population that were administered six vignettes written in the form of police blotters that depicted different crimes being committed by offenders with differing educational characteristics, this study seeks to identify whether or not an offender’s educational characteristics affect their perceived culpability. Although the data indicates that offender’s are seen as culpable regardless of their educational characteristics, it is evident that some degree or sociopathy is assessed to offender’s that are seen as educated and commit both White Collar and Street crimes

A Multivariate Analysis of the Relationship Between Undergraduate Fraternity/Sorority Involvement and Academic Performance

This study explored the relationship between potential time commitments of fraternity and sorority members and academic performance. A secondary analysis of data collected using the Fraternity/Sorority Experience Survey revealed statistically significant relationships between cumulative grade point average and chapter involvement, engagement in academic activities, part-time work, and alcohol use. Chapter involvement, engagement in academic activities, and part-time work were positively associated with academic performance. Alcohol use was negatively related to academic performance. Implications for practice include establishing a culture of academic achievement in fraternal organizations, minimizing the use of alcohol, identifying and approaching academically at-risk members, and establishing initiatives to support the academic achievement of fraternity members

An exploratory study of communication roles as predictors of job satisfaction and management preference.

This investigation explored ways in which communication roles and actor properties are related to job satisfaction and management preferences of organizational members. Expectations relating communication role and actor variables with job satisfaction and management preference were generated from a functional model of communication roles. It was determined that communication role enactment and actor properties are highly significant predictors of expressed levels of job satisfaction and preferences of Theory X and interpersonal relations-oriented management philosophies. Specifically, the data analyses showed that source-receiver and task-socio-emotional distinctions in role enactment and actor properties were most effective for predicting the criterion variables selected for the study.The research design permitted the development of reliability indices for factor structures and predictive validity for the Communication Role Assessment Measure (Cummings, Long, and Lewis, 1979). This favorable assessment lends credence to the rationale and justification for functional communication role research

The More You Put Into It, the More You Get out of It: The Educational Gains of Fraternity/Sorority Officers

The purpose of this study was to determine if undergraduate fraternity and sorority members who serve as chapter officers report different experiences and gains compared to non-officers. The researchers sampled 3,008 fraternity members and 3,745 sorority members from the aggregate results of the institutions that used the AFA/EBI Fraternity/Sorority Assessment during the 2009-2010 academic year. Differences by leadership experience were tested using Cliff’s delta. The researchers found significant differences in the development of chapter officers and non-officers for eight of nine educational gains measures with chapter officers reporting greater gains in these areas. Chapter officers were also more likely to be satisfied with their fraternity/sorority experience than non-officers. There was no statistically significant difference in the alcohol use of officers and non-officers

Age-distribution estimation for karst groundwater: Issues of parameterization and complexity in inverse modeling by convolution

Convolution modeling is useful for investigating the temporal distribution of groundwater age based on environmental tracers. The framework of a quasi-transient convolution model that is applicable to two-domain flow in karst aquifers is presented. The model was designed to provide an acceptable level of statistical confidence in parameter estimates when only chlorofluorocarbon (CFC) and tritium (3H) data are available. We show how inverse modeling and uncertainty assessment can be used to constrain model parameterization to a level warranted by available data while allowing major aspects of the flow system to be examined. As an example, the model was applied to water from a pumped well open to the Madison aquifer in central USA with input functions of CFC-11, CFC-12, CFC-113, and 3H, and was calibrated to several samples collected during a 16-year period. A bimodal age distribution was modeled to represent quick and slow flow less than 50 years old. The effects of pumping and hydraulic head on the relative volumetric fractions of these domains were found to be influential factors for transient flow. Quick flow and slow flow were estimated to be distributed mainly within the age ranges of 0–2 and 26–41 years, respectively. The fraction of long-term flow (\u3e50 years) was estimated but was not dateable. The different tracers had different degrees of influence on parameter estimation and uncertainty assessments, where 3H was the most critical, and CFC-113 was least influential

Prediction of Cardiac Response to Physical Stress

This paper presents a method for predicting an individual's cardiac response to a series of fixed intensity tasks. It was determined that cardiac responses to exercise at given work loads are similar for subjects of the same sex and level of physical fitness when they are expressed in terms of resting heart rate. Using this observation as a basis, a prediction model was developed by extrapolating from emperically derived heart rate patterns. The prediction error was no more than five to ten percent of the actual heart rate value in ninety percent of the predictions.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Chemical Analyses of Water from Selected Wells and Springs in the Yucca Mountain Area, Nevada and Southeastern California

Chemical analysis of water samples from 279 wells and springs in the Yucca Mountain area are presented. Where data are available, this report includes: site location expressed as Nevada Central Coordinates and latitude and longitude; source of data; name of analyzing laboratory; geologic unit from which water was obtained; lithology; water use; elevation of well or spring; well depth; depth to water; time pumped before taking the sample; yield; type of filtration; sampling method; date the sample was collected; and anion-cation balance. Yucca Mountain, Nevada (fig. 1), is being investigated by the U.S. Geological Survey, in cooperation with the U.S. Department of Energy, as a possible repository for the disposal of high-level nuclear wastes. Yucca Mountain is underlain by partially altered volcanic tuffs that probably extend to depths greater than 3,000 m (Snyder and Carr, 1982). If approved, the repository will most likely be excavated within the unsaturated zone, 150 to 300 m above the water table. One concern is that radionuclides might be leached from the stored wastes and eventually reach the saturated zone, where they would be transported in the ground-water system away from the repository. The purpose of this report is to present a data base that consolidates the available ground-water data for the area surrounding the potential Yucca Mountain nuclear-waste repository. The objective of assembling this data is to provide a data base that potentially could be used to help determine: (1) Ground-water flow paths; (2) velocities and residence times of ground water; (3) the degree of vertical and lateral chemical heterogeneity of the ground-water system; and (4) chemical processes that affect the potential movement radionuclide species
