An Examination of How Teacher Tenure and Job Satisfaction Affect Student Achievement

This applied dissertation was designed to examine the correlation between teacher job satisfaction, job retention, tenure and its effect on student achievement and the adjusted cohort graduation rate. This study involved the use of a sequential exploratory qualitative design as a pragmatic philosophical approach to examining the correlation. The researcher utilized three distinct datasets: The OECD Teaching and Learning International Survey (TALIS) 2018; The National Center for Educational Statistics, Adjusted Cohort Graduation Rate; and the Ohio Department of Education, Ohio Teacher Evaluation System. An analysis of the data revealed that statistically significant themes emerged among the datasets for the job satisfaction and job retention of teachers. The most successful themes involved hierarchy of needs characteristics such as: equitable compensation, employment contract length, coworker relationships, working environment, self-efficacy, and self-actualization. Obviously, these findings raise questions about the dynamic and credibility of the hierarchy of needs for teachers and their correlation in motivating students to achieve the adjusted cohort graduation rate. As, current research provided little to no evidence to suggest the correlation between teacher job satisfaction, job retention, tenure and how it affects student achievement. Characteristic variables, which have frequently been used to define high value teachers, such as value-added models (VAMs) purport to be able to identify a teacher’s effect on students’ test scores. Even though VAMs evaluate a teachers’ contribution in any given year by comparing current test scores of students to the previous year, value-added modeling completed dismisses the correlation of the hierarchy of needs for teachers to student achievement and the adjusted cohort graduation rate

A vacuum induction furnace for pyrometric cone equivalent determinations

Various furnaces which are commonly used for P.C.E. determinations were compared from a literature review. The inadequacies of these furnaces were noted and a furnace was designed, constructed, and evaluated in an effort to minimize or eliminate some of the indicated problems. For this furnace heat is developed in opposed cones (susceptors), which are fabricated from 0.005” molybdenum sheet, by induced (induction) currents from a 10 KW vacuum tube generator. The furnace components are enveloped by a pyrex cylinder in which a vacuum (approximately 1 to 5 micron pressure absolute) is maintained during operation --Abstract, page ii

Heavy minerals of the Cretaceous Hell Creek and Paleocene Ludlow Formations of Slope and Bowman counties, North Dakota

The Cretaceous Hell Creek and Paleocene Ludlow Formations of southwestern North Dakota are nonmarine sediments of alluvial origin. The heavy minerals of these formations were specifically studied to determine the source rock types and their provenance, and generally assess the diagenetic processes which affected the heavy minerals. The heavy minerals include zircon, rutile, tourmaline, garnet, ilmenite, spinel, apatite, epidote, sphene, pyroxene, dolomite, biotite, andalusite, pyrite, monazite, and barite. Most of the heavy minerals have angular shapes, indicating one cycle of erosion and deposition. The heavy mineral percentages of the concretions and surrounding sediments were compared within and between the Hell Creek and Ludlow Formations using linear discriminant analysis. The comparisons between the heavy mineral percentages of the concretions and surrounding sediments within the Hell Creek and Ludlow Formations showed no significant differences. The comparison of the concretions of the Hell Creek and Ludlow Formations showed no significant difference in the heavy mineral percentages. The heavy minerals in the surrounding sediments of the Hell Creek and Ludlow Formations are significantly different at the .99 confidence level. The T test was used to compare the mean heavy mineral values of the concretions and surrounding sediments between the Hell Creek and Ludlow Formations. The results of the T-test support the results of the linear discriminant analysis. The comparison of the heavy mineral means of the surrounding sediments, between the Hell Creek and Ludlow Formations shows that tourmaline, rutile, epidote, garnet and zircon are significantly different. In the comparison of the mean heavy mineral values of the concretions between the formations only garnet was significantly different. The difference between the heavy mineral percentages of the concretions and surrounding sediments within each formation has been attributed to the re placement of minerals by calcite within the concretions. The difference between the heavy mineral percentages of the Hell Creek and Ludlow surrounding sediments is probably due to subtle changes in source rock types from the Hell Creek to Ludlow time. The source rock types associated with the heavy minerals in these two formations are volcanic and intrusive igneous, thermal metamorphic, and reworked sedimentary rocks. The provenance of these sediments is thought to be the Elkhorn Mountains Volcanic Complex and adjacent rocks of western Montana, because of the similar mineralogies and timing (82 myrs to 71 myrs) and volume of volcanic activity in the complex. The comparison of the heavy mineral percentages indicates no major change in provenance from Hell Creek to Ludlow time

Network Propaganda

"Is social media destroying democracy? Are Russian propaganda or ""Fake news"" entrepreneurs on Facebook undermining our sense of a shared reality? A conventional wisdom has emerged since the election of Donald Trump in 2016 that new technologies and their manipulation by foreign actors played a decisive role in his victory and are responsible for the sense of a ""post-truth"" moment in which disinformation and propaganda thrives. Network Propaganda challenges that received wisdom through the most comprehensive study yet published on media coverage of American presidential politics from the start of the election cycle in April 2015 to the one year anniversary of the Trump presidency. Analysing millions of news stories together with Twitter and Facebook shares, broadcast television and YouTube, the book provides a comprehensive overview of the architecture of contemporary American political communications. Through data analysis and detailed qualitative case studies of coverage of immigration, Clinton scandals, and the Trump Russia investigation, the book finds that the right-wing media ecosystem operates fundamentally differently than the rest of the media environment. The authors argue that longstanding institutional, political, and cultural patterns in American politics interacted with technological change since the 1970s to create a propaganda feedback loop in American conservative media. This dynamic has marginalized centre-right media and politicians, radicalized the right wing ecosystem, and rendered it susceptible to propaganda efforts, foreign and domestic. For readers outside the United States, the book offers a new perspective and methods for diagnosing the sources of, and potential solutions for, the perceived global crisis of democratic politics.

Achieving Successful Long-Term Recovery and Safety from a Catastrophe: Recommendations for Public Assistance

There have been numerous complaints, testimonies, studies, reports and recommendations regarding problems with the Public Assistance (PA) program after Hurricanes Katrina and Rita. Congress has addressed some of them as part of the Post Katrina Emergency Management Reform Act (PKEMRA) and continues to monitor progress in FEMA and in the field. Our report today draws upon the existing literature and our own investigations in Louisiana and Mississippi to reach a series of findings about the nature of aid needed in catastrophes and to offer recommendations

The collisional de-excitation of neon at various pressures.

It was proposed to observe the spectral intensities of the 5852. 5A o line in Neon I, and 3664. 1A line in Neon II to obtain collisional deexcitation cross sections, a,, and de-excitation reaction rates, K... d 1 However, due to a series of problems with the Van De Graaff accelerator in the proton configuration no reproducible data was obtained. The majority of the time was thus spent converting the accelerator to the electron configuration and attempting to make the system operational o again. In this light trial runs were made on the 3371. 3A spectral line of nitrogen using electrons as the excitation source. Values obtained in these runs were off by a factor1 of one thousand from those obtained by A. R. Smelley [Ref. M] using protons.http://archive.org/details/collisionaldeexc00farrMajor, United States ArmyApproved for public release; distribution is unlimited
