An Investigation of the Awareness of Recycling Services at Student Family Housing UnitsAba, Eli KofiThis research investigated the awareness of recycling programs at student family housing units at Indiana State University. The purpose of this research was to find out the awareness of recycling in these areas. It allowed the researcher to examine the recycling awareness among other variables such as willingness to take part in pickup and willingness to take part in drop-off, among students at these areas. The researcher employed IRB (Institutional Review Board) approved survey to survey students who resided in four units, and who were willing to participate in the study. An introduction of the researcher, his background and objectives of the study, along with contact information of the researcher, the committee chair, and the IRB was given to each participant The researcher used systematic sampling to sample the population to get the 240 sample size. Based on a coin toss, every odd apartment number from the apartment numbers of the family housing units was selected for the one-month survey. The data was coded into value labels and recorded in SPSS for a statistical analysis. Bar charts, chi-square, and cross-tabulations were used for the analysis of the data at 0.05 significance levels. Descriptively, 59 % family housing residents were not aware of recycling program. However, 88 % of them believed that recycling would help them dispose of their trash. 78 % of them were willing to take part in pickup, while 70 % would also do so in drop-off. About 45 % were confident that the recycling center would recycle the materials they sorted for recycling,while 22 % recorded inconvenience as the reason for not taking part in both pickup and drop-off programs. About 34 % wanted ISU authorities to promote pickup recycling in order to make recycling appealing or convenient to them. All the null hypotheses were retained except there were statistically significant differences between the awareness of recycling center, awareness of recycling program, willingness to take part in pickup, willingness to take part in drop-off counts and the two categories of nationality of students, and the awareness of recycling center and gender counts.
Impact of ISO 9001 Certification on United States Firms’ Financial PerformanceAba, Eli KofiOne of the greatest demands in our global economy that have compelled firms to invest increasingly in resources for the enhancement of their management practices is organizational competitiveness. Standards have played an increasingly important role in economic and market globalization. Studies on the financial impact of ISO 9001 on firms are still inadequate to make definitive conclusions on the financial impact of ISO 9001 on firms. Furthermore, there is no clear position on the financial benefits of ISO 9001 standard in literature. Therefore, the researcher investigated the impact of ISO 9001 certification on United States firms’ financial performance for a period of five years including one-year prior to certification, year of certification, and three fiscal years after certification. A sample of 397 firms that had received ISO 9001 certification from 1991 to 2002 was examined. Certified-firm and non-certified-firm operating performances were examined over the same period based on the ratio of pre-tax operating income to total assets (EBITA/TA). Wilcoxon signed-rank test was used to test for significant differences in operating performance between the firms. There was significant improvement performance from prior year to year of certification. The certified firms performed better in the five-year period than the non-certified and the matched-control firms.
