Church Attendance: Another Look

This thesis investigates the effect of nine sociological variables on church attendance in two churches in Bowling Green, Kentucky. The sample was drawn from a Church of Christ (N=135) and a Southern Baptist church (N=105). The effects of these variables were determined by using the computer program Multiple Nominal Scale Analysis. The explanatory variables examined with church attendance were other religious activity, education, occupation, income, meaning, belonging, conservatism/ orthodoxy, a general sense of meaning, and the number of other voluntary associations belonged to. Meaning was defined as the belief that one belonged to the New Testament Church. Belonging was divided into two variables; the number of closest friends that attended one\u27s congregation and the number of closest friends in one\u27s denomination. Eight other variables were examined for their effect on belonging, defined as the number of closest friends in one\u27s congregation. They were how many years the subject has been attending his present church, how many years he has been a member of his present church, whether or not the subject\u27s mother and father are living and whether or not each of them attended church, and if so where. Subjects were also asked how long they had lived in or near Bowling Green, Kentucky, and the occupations of one\u27s five closest friends. The findings indicate that in both churches other religious activity was the most powerful predictor of church attendance. In the Church of Christ this was followed by belonging, defined as the number of closest friends in one\u27s congregation, and meaning. In the Baptist church social status variables such as income, number of other voluntary organizations belonged to and occupation ranked below other religious activity. This supported the principal hypothesis that attendance in the Church of Christ would be higher and that meaning and belonging would be better predictors of church attendance here than in the Baptist church. Concerning belonging, the findings indicate that the occupations of one\u27s closest friends is important in both churches but where the combined variable of number of years one has attended his present church and number of years he has been a member are important in the Baptist church, the background variable of the church one\u27s father attended is more important in the Church of Christ

Evaluation of risk and protective factors of substance use in the national association of intercollegiate athletics.

The NCAA and NAIA have conducted prevalence studies of substance use in their organizations but little research into risk and protective factors that influence usage. Substance use is associated with an array of consequences including negative academic impacts, criminal charges, health risks, and mental health. As the most reported substances used by student-athletes the study focused on alcohol, marijuana, and nicotine. This study specifically examined several risk and protective factors impacting substance use. This study utilized a secondary data analysis of information gathered from the NAIA Substance Use and Abuse Study conducted in 2020 with student-athletes (N=2489). Descriptive statistics, parametric tests, non-parametric tests, and multiple regression was utilized to conduct statistical analysis for the research questions. The researcher created composite variables of substance use that incorporated self-reported levels of current usage for alcohol, marijuana, and nicotine. Data for the three identified substances of interest were combined to create a global score of substance use. There were multiple significant findings identified in this research study. The first was reported levels of substance use significantly increased for males 21 and above from those 18-20. Substance use at public universities was significantly higher than at private universities, with the lowest usage at private faith-based institutions. Data shows that who a student-athlete lived with impacted their substance use and those living with fellow athletes have the highest rates of usage. A significant factor analyzed in this study for influencing current substance use was when they started using i.e., before high school, high school, or college. Results support that athletic departments need to address substance use for male athletes 21 and older. Public universities need to evaluate private institutions, specifically private faith-based institutions, to better understand what can be done to decrease substance use on their campuses. Athletic departments at the college and high school level should work to identify athletes with substance use early, increase education, and examine potential evidence-based interventions to decrease substance use. One potential concept for creating a positive impact on substance use among student-athletes is the incorporation of social workers in athletic departments and organizations across college sports

Observational analysis of cumulus and stratocumulus entrainment using ozone

October 1987.Also issued as Clark Jay Weaver's dissertation (Ph.D.) -- Colorado State University, 1987.Includes bibliographical references.This study demonstrates that ozone mixing ratio (03) is conserved during moist convection and can be used as a tracer for cloud entrainment studies. The approach in Part I is to apply mixing line analysis to pairs of Oe, 01, total water mixing ratio and 03 derived from aircraft penetrations of growing cumulus congestus. Conclusions about entrainment from the mixing diagrams employing 03 agree with those using thermodynamic quantities. Any disagreement uncovered deficiencies in the water substance measurement technique. Ozone is conserved / and recommended for future entrainments studies. Other conclusions were that strong updrafts, thought to be a diluted adiabatic core, entrained laterally from the environment at the observation level. In contrast, the downshear region of the cloud entrained air from above the observation level as well as laterally. Entrainment instability is thought to be a cause of stratocumulus break up. At the cloud-overlying air interface, mixtures may form which are negatively buoyant due to cloud droplet evaporation. In Part II, quantities devised to predict breakup, ~ 2 , X and ~m, are obtained from aircraft observations and are tested against cloud observations from satellite. Often, the parameters indicate that breakup should occur but the clouds remain, sometimes for several days. One possible explanation for break up is vertical motion from passing synoptic cyclones. Several cases suggest that break up is associated with the downward vertical motion from the cold air advection behind a eastward moving cyclone.Sponsored by the National Science Foundation ATM-8114575, ATM-8312615, ATM-8311405, and ATM-8614956

Technical characteristics of the OmniTRACS: The first operation mobile Ku-band satellite communications system

The techinical characteristics of the OmniTRACS system are described. The system is the first operational mobile Ku-band satellite communications system and provides two-way message and position determination service to mobile terminals using existing Ku-band satellites. Interference to and from the system is minimized by the use of special spread-spectrum techniques, together with low power and low data rate transmissions
