No full textA. Solomonson & W. Kerr Minnesota State University, Mankato, MN
Purpose: We investigated the use of the 3 minute all-out running test for use with tactical populations, examining the difference between externally loaded (18.63 kg) and unloaded 3 min-all out running test running test performance, comparing maximal steady state (CS) and curvature constant (D’) with respect to percent of body mass of the external load. Methods: Seven recreationally active subjects participated in two 3 minute all-out running tests, one weighted, using an adjustable weight vest, and another un-weighted. Critical Speed and curvature constants (D’) were established for both trials. Comparisons were made using ∆CS and ∆D’ between weighted and un-weighted trails, with the percentage of body mass that the vest represented. Results: Critical speeds and D’ of weighted and un-weighted trails were 3.11± .33 m/s, 225.93±44.43 m and 3.85±.44 m/s, 200.10±35.42 respectively. ∆CS and ∆D’ were .74±.26 m/s and -26.55±40.64 m. Change in critical speed when compared to % body mass (BM) had an R value of .73, while the R value comparing ∆D’ and %BM was .17. Conclusions: Similar to the un-weighted 3MT performance, running velocity quickly peaked and subsequently declined to a steady state approximately during the last 30 s. of the test. As expected the change in critical speed correlated with the % BM that the vest represented, leading to the assumption that exercise performance is less affected by the addition of an external load than that of those which the external load represents a greater percentage.

Over The Edge: Factors Nudging Mid-Career, School-Based Agriculture Teachers Out of the Profession
No full textThe field of agricultural education has experienced a consistent labor shortage the past several decades. Consequently, many school districts struggle to fill their open positions, while others are forced to shut down their agricultural programs completely due to inadequate staffing. Teacher attrition has been identified as a predominant factor behind the teacher shortage. The purpose of this mixed-methods study was to identify factors influencing mid-career school-based agriculture teachers’ decision to stay in or leave the secondary agriculture teaching profession. Researchers developed and administered questionnaires, as well as conducted interviews, to gather data from current, mid-career agriculture teachers to answer the research questions. The researcher’s discovered mid-career agriculture teachers are satisfied with their careers and significant differences do not exist in overall job satisfaction between those contemplating leaving and those who were not. However, differences existed between groups in areas related to recognition and school policy and administration. Additional findings suggest mid-career agriculture teachers value student and program successes, autonomy and variety, and stakeholder support. Moreover, the researcher’s discovered mid-career agriculture teachers experience similar frustrations as teachers in other professional life stages; however, they seem to struggle more with balancing their personal and professional lives due to changing family dynamics.This article is published as Solomonson, J.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Why Do They Leave and Where Do They Go? A Qualitative Study of Illinois School-Based Agriculture Teachers Who Left The Profession
No full textApproximately half of a million educators move or leave the profession each year with an estimated 41% of all educators exiting within the first five years. Additionally, agriculture teacher preparation programs are not producing enough graduates to meet current demands with 1,476 agricultural teacher vacancies existing in 2016 and only 772 individuals completing an approved teacher preparation program to become fully licensed. While the lack of young people entering the teaching profession is concerning, researchers have suggested teacher attrition is the predominant reason behind the ongoing teacher shortage. The purpose of this qualitative study was to identify factors influencing former agriculture teachers’ decision to leave the classroom. Themes developed that stem from unrealized expectations for one’s career and the belief that being an excellent agriculture teacher is incompatible with a satisfying personal life. A final theme indicated the need for additional support alongside a philosophical shift in the profession that dictates “more is not always better.” Recommendations are made for further research along with ideological and practical shifts needed within the profession to improve teacher retention.This article is published as Solomonson, J.

Factors contributing to Illinois school-based agriculture teachers’ final decision to leave the classroom
No full textTeacher attrition is a significant problem nationally and a special challenge for school-based agriculture education programs. The purpose of this study was to investigate contributing variables associated with former Illinois school-based agriculture teachers and their decision to leave the profession. A four-factor conceptual model is proposed as a framework for explaining agriculture teacher retention or attrition and includes the multivariate constructs of Personal Factors, Working Conditions, Teacher Development, and Compensation. Demographic characteristics are explored as well as difference between novice and experienced teachers and their perceptions of attrition influences. This study is unique in that it reports survey data from teachers who have left the profession (n = 91) and explores their reflective perceptions about reasons for leaving. Among all teachers, Personal Factors and Teacher Development were found to have the most impact on decisions to leave the profession. Compensation was found to be a more significant attrition influence for novice teachers than for experienced teachers. Recommendations for organizations hoping to promote agriculture teacher retention are discussed.This article is published as Solomonson, J. K., Korte, D. S., Thieman, E. B., Retallick, M.

fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
