Persistence of Career Choice Among Graduates of the College of Education, Louisiana State University, Baton Rouge Campus.

The purpose of the study was to investigate the existence or non-existence of patterns and trends regarding the persistence of career choice among graduates of the College of Education, Louisiana State University, Baton Rouge Campus. The problem was stated as: 1. What are the patterns in the persistence of career choice among graduates of the College of Education, Louisiana State University, Baton Rouge, during their undergraduate studies? 2. What are the trends in the persistence of career choice among graduates of the College of Education, Louisiana State University, Baton Rouge, during their undergraduate studies? The population, 1,141 students, represented the years 1960, 1965 and 1970. Each year group was examined in isolation for the purpose of identifying any significant patterns, while the total group was examined for possible trends. Students were examined on the basis of their records in the College of Education. The research design called for the evaluation of year groups on the basis of: 1. Sex--male versus female 2. Classification--the student\u27s university classification at the time of entrance into the College of Education. 3. Curriculum--the course of study chosen by the student. 4. Continuity of Enrollment--excluding the surmner sessions, the consistency of continued enrollment in Louisiana State University, Baton Rouge The following conclusions were reported as trends: 1. Women outnumbered men in all areas of this study. 2. The number of men graduating from the College of Education decreased. 3. During the decade under study an increasing percent of the graduates did not enter the College of Education from Junior Division. 4. Most female elementary majors chose the lower elementary program while most male elementary majors chose the upper elementary program. 5. Physical education and Ul.lsic education majors were more persistent than students in either of the other two general curriculums. 6. Among all secondary majors, social studies was the most frequently chosen major. 7. Among all secondary majors, social studies and English were the most frequently chosen minors. 8, For the period under study, more women than men came to the College of Education from other Louisiana Colleges and out-of-state institutions. 9. The fact that only 68 students broke their continuity of enrollment indicates that persistence was high during the study period in the College of Education. 10. Sixty-four of the 68 students breaking continuity of enrollment had come from Junior Division. 11. The majority of the breaks in continuity resulted from changes in curriculum within the College ot Education. Changing from the elementary curriculum to the secondary curriculum or from secondary to elementary were the common breaks of this kin

Kolker is with Louisiana Universities Marine Consortium, Chauvin, LA, USA. -- Wei Wu is with the Department of Coastal Sciences, Gulf Coast Research Laboratory, The University of Southern Mississippi, Ocean Springs, MS, USA.Background: Coastal sediments in the northern Gulf of Mexico have a high potential of being contaminated by petroleum hydrocarbons, such as polycyclic aromatic hydrocarbons (PAHs), due to extensive petroleum exploration and transportation activities. In this study we evaluated the spatial distribution and contamination sources of PAHs, as well as the bioavailable fraction in the bulk PAH pool, in surface marsh and shelf sediments (top 5 cm) of the northern Gulf of Mexico. Results: PAH concentrations in this region ranged from 100 to 856 ng g−1, with the highest concentrations in Mississippi River mouth sediments followed by marsh sediments and then the lowest concentrations in shelf sediments. The PAH concentrations correlated positively with atomic C/N ratios of sedimentary organic matter (OM), suggesting that terrestrial OM preferentially sorbs PAHs relative to marine OM. PAHs with 2 rings were more abundant than those with 5–6 rings in continental shelf sediments, while the opposite was found in marsh sediments. This distribution pattern suggests different contamination sources between shelf and marsh sediments. Based on diagnostic ratios of PAH isomers and principal component analysis, shelf sediment PAHs were petrogenic and those from marsh sediments were pyrogenic. The proportions of bioavailable PAHs in total PAHs were low, ranging from 0.02% to 0.06%, with higher fractions found in marsh than shelf sediments. Conclusion: PAH distribution and composition differences between marsh and shelf sediments were influenced by grain size, contamination sources, and the types of organic matter associated with PAHs. Concentrations of PAHs in the study area were below effects low-range, suggesting a low risk to organisms and limited transfer of PAHs into food web. From the source analysis, PAHs in shelf sediments mainly originated from direct petroleum contamination, while those in marsh sediments were from combustion of fossil fuels.Marine [email protected]
