An Evaluation of Twenty Modern Elementary Arithmetic Textbooks

An Evaluation of Twenty Modern Elementary Arithmetic Textbooks

Date: 1950
Creator: Murphree, Bessie
Description: The purpose of this study is threefold: (1) to review briefly important studies and recommendations relating to curriculum construction in elementary arithmetic; (2) to develop a set of criteria for judging elementary arithmetic textbooks; and (3) to apply the criteria to a selected number of elementary arithmetic textbooks.

An Evaluation of Two Methods of Teaching Social Studies in Junior High School

An Evaluation of Two Methods of Teaching Social Studies in Junior High School

Date: 1950
Creator: King, Oma Allie
Description: The objective of this study is to evaluate the effectiveness of two methods of teaching the social studies to junior high school pupils. An attempt has been made to ascertain the relative progress in the studying efficiency of a group of children in social studies taught by the basic-study-skills plan, as compared to that of a group of children taught by the assign-study-recite-test plan so commonly employed.

An evaluation of two performance pay systems on the productivity of employees in a certified public accounting firm.

An evaluation of two performance pay systems on the productivity of employees in a certified public accounting firm.

Date: December 2005
Creator: Shelton, Bryan
Description: This study examined the effects of switching from an incentive pay system solely based on productivity to a scorecard-based incentive pay system. Performance of staff and senior accountants was analyzed across three departments for a two-year baseline and a three-year intervention period. Results showed that percent of charge hour goal remained high during the study. Once the scorecard-based incentive system was implemented, performance on the other line items increased or remained at or above goal levels. Incentive payouts were generally higher under the second incentive plan than under the first for top performers. Possible explanations for data trends, weaknesses of the measures within the scorecard, measure/line item alternatives and implications for future research are also discussed.

Evaluation of virulence in wild type and pyrimidine auxotrophs of  Pseudomonas aeruginosa using the eukaryotic model system  Caenorhabditis elegans.

Evaluation of virulence in wild type and pyrimidine auxotrophs of Pseudomonas aeruginosa using the eukaryotic model system Caenorhabditis elegans.

Access: Use of this item is restricted to the UNT Community.
Date: August 2004
Creator: Anvari, Sara
Description: The human opportunistic pathogen, Pseudomonas aeruginosa PAO1, has been shown to kill the nematode Caenorhabditis elegans. C. elegans has been a valuable model for the study of bacterial pathogenesis, and has reinforced the notion that common virulence and host defense mechanisms exist. Recently, the pyrimidine pathway was shown to regulate virulence levels. Therefore, mutations in the pyrimidine pathway of PAO1 showed decrease virulence in the nematode. When starving the nematode, bacterial resistance was also shown to increase. It was hypothesized that starvation induced the DAF pathway, which regulates the transcription of genes involved with the antibacterial defense mechanism. Further research will be conducted to test this theory by performing RNAi experiments for the genes functioning in the antibacterial defense mechanism.

The Evaluation of Youth Workers in Institutions for Juvenile Delinquents

The Evaluation of Youth Workers in Institutions for Juvenile Delinquents

Date: January 1962
Creator: Walther, Richard Ernest
Description: The purpose of the study was to determine trends between selected factors in the study. Trends between thirty position qualifications and proficiency with children, proficiency with staff, education, age, sex, and length of service were examined, trends between the type of institution, areas of duty, and general proficiency were also examined.

Evaluation of zinc toxicity using neuronal networks on microelectrode arrays: response quantification and entry pathway analysis.

Evaluation of zinc toxicity using neuronal networks on microelectrode arrays: response quantification and entry pathway analysis.

Date: August 2007
Creator: Parviz, Maryam
Description: Murine neuronal networks, derived from embryonic frontal cortex (FC) tissue grown on microelectrode arrays, were used to investigate zinc toxicity at concentrations ranging from 20 to 2000 mM total zinc acetate added to the culture medium. Continual multi-channel recording of spontaneous action potential generation allowed a quantitative analysis of the temporal evolution of network spike activity generation at specific zinc acetate concentrations. Cultures responded with immediate concentration-dependent excitation lasting from 5 to 50 min, consisting of increased spiking and enhanced, coordinated bursting. This was followed by irreversible activity decay. The time to 50% and 90% activity loss was concentration dependent, highly reproducible, and formed linear functions in log-log plots. Network activity loss generally preceded morphological changes. 20% cell swelling was correlated with 50% activity loss. Cultures pretreated with the GABAA receptor antagonists bicuculline (40 mM) and picrotoxin (1 mM) lacked the initial excitation phase. This suggests that zinc-induced excitation may be mediated by interfering with GABA inhibition. Partial network protection was achieved by stopping spontaneous activity with either tetrodotoxin (200 nM) or lidocaine (250 mM). However, recovery was not complete and slow deterioration of network activity continued over 6 hrs. Removal of zinc by early medium changes showed irreversible, catastrophic ...

Evaluation Practices of Community College Faculty Development Programs

Evaluation Practices of Community College Faculty Development Programs

Date: December 2014
Creator: Bunyard, Magen Lynn
Description: The purpose of this quantitative study was to determine the current state of community college faculty development program evaluation and identify possible influences on evaluation practices. Data from 184 survey responses and the Integrated Postsecondary Education Data System (IPEDS) were analyzed to answer three research questions. Multiple regression was used to determine if a relationship existed between the dependent/outcome variable (evaluation utilization score) and the independent/predictor variable (accrediting agency affiliation: MSCHE, NEASC, NCA, NWCCU, SACS, and WASC) and/or control variables (institution locale, student FTE, expenses per student FTE, percent spent on instruction, and percent of full-time faculty). Results were not statistically significant, F (12, 163) = 1.176, p = .305. The mean evaluation scores were similar for all six accrediting agencies ranging from 60-69. The rural variable was statistically significant with p = .003 and alpha = .05, but it only accounted for 3.6% of the variance explained. Logistic regression was used to determine if a relationship existed between the dependent/outcome variable (use of evaluation) and the above-specified independent/predictor variable and/or control variables for six faculty development program activities. Results revealed that significant predictor variables for the use of evaluation vary based on the faculty development program activity. Statistically significant ...
