Proportions of r-regular elements in finite classical groups

For a prime $r$, we obtain lower bounds on the proportion of $r$-regular elements in classical groups and show that these lower bounds are the best possible lower bounds that do not depend on the order of the defining field. Along the way, we also provide new upper bounds and answer some open questions of the first author, P\'{a}lfy and Saxl.Comment: 22 page

Entrepreneurship: a unit experimentally implemented in secondary vocational home economics programs

The purpose of this study was to experimentally evaluate the implementation of a unit exploring entrepreneurship as a career option in secondary vocational home economics programs. The study was conducted in three phases which included: (1) research on home economics related small businesses and their owners, (2) pilot test of the career exploration unit on entrepreneurship, and (3) field test of the unit in twelve secondary vocational home economics classes;A survey was conducted to determine characteristics of home economics related small businesses and their owners in Iowa. Ninety-five women and 84 men, 56% of the invited sample, completed the questionnaire in 1979. Chi square values were computed to identify significant differences between male and female owners;Female small-business owners earned less money, started with less capital, and had lower gross receipts than male small-business owners. Men had more managerial experience prior to business ownership, yet women were older than men when starting their first business;The pilot test of the career exploration unit in three classes indicated that entrepreneurship was a viable topic for vocational home economics classes. High school students were able to understand entrepreneurial concepts and classroom teachers were enthusiastic about the topic;A nonequivalent control group design was used to experimentally evaluate the implementation of the unit for the field test. Two types of vocational home economics programs were used: (1) consumer and homemaking and (2) occupational programs;Achievement test data were analyzed by class mean scores in an analysis of covariance (ANACOVA) design. Significant differences were found with the experimental group having higher mean scores than the control group. Type of home economics program did not produce significantly different mean scores. The attitude device was analyzed using class means for individual items in an ANACOVA design. Some significant differences were found, but overall impact on student attitudes was not tremendous;Teacher and student evaluation instruments were assessed by content analysis. Teacher believed career exploration of entrepreneurship was appropriate in both consumer and homemaking and occupational classes. Students enjoyed reviewing entrepreneurial concepts and exploring entrepreneurship as a career

Forced Isolation in an Era of Inclusion Within U.S. K-12 Public School Communities

The COVID-19 pandemic brought to the forefront disparities and inequities in U.S. K–12 public school systems that affected both educators and the students they served—not only during school closures but also after in-person instruction resumed. The purpose of this scholarly essay is to shed light on the levels of isolation that occurred during the pandemic and still affect educators in K–12 public schools as they seek to foster academically rigorous and inclusive school communities. Recognizing, and then quickly responding to, historic events by implementing strategies that take into account the social determinants of learning and health is the starting point to helping the education stakeholders heal, which will then facilitate students to regain their personal and academic confidence and abilities as we move to a post-pandemic world

Insulin Pump Class: Back to the Basics of Pump Therapy

Insulin pump therapy is a common mechanism for insulin delivery in Type 1 diabetes mellitus as well as in some patients with Type 2 diabetes mellitus. At the Longstreet Clinic, approximately 3% of patients on insulin therapy utilize insulin pumps. After several patients on insulin pump therapy experienced severe hypoglycemic episodes while driving, the need for review of insulin pump survival skills were identified. The insulin pump class which was conducted in a small group setting reviewed all of the necessary survival skills for effective insulin pump therapy. Pre- and post-class hemoglobin A1c values and emergency room visits as well as patient satisfaction survey were the measured outcomes

Education Licensure Candidates During the Time of COVID-19: University Supervisors’ Reflections About the Forgotten Few

Education at K–12 through university levels has faced extraordinary upheaval in the time of COVID-19. As universities and K–12 school systems struggled independently to adapt to rapidly changing demands, teacher and administrator licensure candidates were confronted with unprecedented challenges in both worlds simultaneously. The licensure candidates were the forgotten few, stuck between higher education and K–12 education, while struggling to keep up with the demands of their personal lives and professional futures. With limited guidance from their universities and school systems, licensure candidates turned to their university field placement supervisors for direction. In response, supervisors became adaptive leaders and flexible problem solvers with compassionate hearts focused on supporting candidates’ success against all odds. Through the reflections of university supervisors, this scholarly essay provides a window into the unique experiences of education licensure candidates and their university supervisors as they navigate the worlds of higher education and K–12 education

DEVELOPING A PRINCIPAL INDUCTION PROGRAM FOR CRAVEN COUNTY SCHOOLS

The demands of principals have increased drastically over the years and principals are overwhelmed as they accept the responsibility for an entire school. With an emphasis on performance and accountability and realizing that the principal’s contribution to student learning is second only to the teacher, school districts are seeking tools to develop highly effective principals. This study investigated the problem of too few experienced administrators in Craven County Schools. The problem of practice grew out of concern from Superintendent Dr. Lane Mills and the district leadership team as they reviewed the experience levels of the principals. The questions examined were: 1. Using the continuous improvement model, what is the comprehensive design of a Principal Induction Program to prepare school leaders for effective leadership in Craven County? 2. Based on the literature review, anecdotal notes, surveys, emotional intelligence test, and interviews, what components are deemed essential to be a highly qualified principal in Craven County? The results of the data collected found: (1) The principalship requires a multidimensional leader (2) Principals of various experience levels perceive themselves differently than others; and (3) Principals support should include a multifaceted approach through individualized and cohort based activities. Findings from this research reinforced the importance of a Craven County Principal Induction Program. The data collected will be used in preparing Craven County Schools’ administrators for the work of a twenty-first century principal, one who focuses on learning and balances the managerial responsibilities. Z. Smith Reynolds recognized the Craven County Schools commitment to leadership and the district was awarded a grant of ninety thousand dollars to ensure that support for their leaders continue

A new experimental approach for studying bacterial genomic island evolution identifies island genes with bacterial host-specific expression patterns

BACKGROUND: Genomic islands are regions of bacterial genomes that have been acquired by horizontal transfer and often contain blocks of genes that function together for specific processes. Recently, it has become clear that the impact of genomic islands on the evolution of different bacterial species is significant and represents a major force in establishing bacterial genomic variation. However, the study of genomic island evolution has been mostly performed at the sequence level using computer software or hybridization analysis to compare different bacterial genomic sequences. We describe here a novel experimental approach to study the evolution of species-specific bacterial genomic islands that identifies island genes that have evolved in such a way that they are differentially-expressed depending on the bacterial host background into which they are transferred. RESULTS: We demonstrate this approach by using a "test" genomic island that we have cloned from the Salmonella typhimurium genome (island 4305) and transferred to a range of Gram negative bacterial hosts of differing evolutionary relationships to S. typhimurium. Systematic analysis of the expression of the island genes in the different hosts compared to proper controls allowed identification of genes with genera-specific expression patterns. The data from the analysis can be arranged in a matrix to give an expression "array" of the island genes in the different bacterial backgrounds. A conserved 19-bp DNA site was found upstream of at least two of the differentially-expressed island genes. To our knowledge, this is the first systematic analysis of horizontally-transferred genomic island gene expression in a broad range of Gram negative hosts. We also present evidence in this study that the IS200 element found in island 4305 in S. typhimurium strain LT2 was inserted after the island had already been acquired by the S. typhimurium lineage and that this element is likely not involved in the integration or excision of island 4305. CONCLUSION: The "clone-and-transfer" approach of evolutionary study identifies genes whose expression patterns indicate the existence of genera-specific regulatory mechanisms that influence the expression of horizontally-transferred DNA sections. The results provide key information that can be used to facilitate the identification of these regulatory mechanisms

Interdisciplinary Collaborative Research for Professional Academic Development in Higher Education

Although faculties are more diverse, decentralized, and increasingly isolated in technology-supported modern universities, effective technology use can also foster faculty professional academic development and collegiality. This scoping literature review applied Cooper’s systemic review model and a categorical content analysis technique targeting decentralized collaborative research teams in higher education. Findings indicate technology supports formal and informal university and nonuniversity networks, as well as various collaborative research structures; all contributing to professional academic development. Shared attributes of successful collaborative online teams include a sense of social presence, accountability, institutional and team leadership. Collaborative teams are integral to research and allow more faculty members to contribute and benefit from professional academic development through scholarship. Collaborative team research should be investigated further to understand and promote cross-discipline and cultural collaboration potential for research and professional academic development possibilities with special attention given to opportunities for women, online, and adjunct facult
