A Handbook for the Beginning Teacher in Elementary School Physical Education

This handbook is the outgrowth of a desire on the part of the writer to provide helpful, easily accessible information to aid the beginning teacher in elementary-school physical education. The need for such information impressed the writer when as a teacher in elementary-school physical education she found few sources of helpful facts available. This handbook represents and effort to fulfill this need by presenting organized facts which may answer questions to many of the frequently encountered problems. It is hoped that the reader will not regard the information herein as mandatory for usage, but rather as suggestions which may be of help to the beginning teacher. Chapter I presents a discussion of the importance of special teacher introduction for the elementary-school physical education program. Chapter II points out items of primary importance to the beginning teacher and offers suggestions for dealing with each item. These suggestions are centered around such areas as an adequate philosophy of physical education, its policies, proper selection of activities, scheduling of classes, teaching load, lesson planning, safety, discipline, community relationships and school relationships. Chapter III contains a discussion of the concept of evaluation and its place in the elementary school program

Advantages and Disadvantages of Using Internet-Based Survey Methods in Aviation-Related Research

Within the last decade, numerous online populations, such as SurveyMonkey ® and Amazon’s ® Mechanical Turk ®(MTurk), have been established allowing researchers to gather data involving diverse populations. These resources offer an alternative to traditional laboratory settings hosted at universities, where many studies utilize students as the available and accessible population. While these online portals do provide new opportunities, they also contain unique advantages and disadvantages. This paper synthesizes the advantages and disadvantages of using online populations to conduct research in the aviation field. Some of the advantages are: easier access to new populations, larger sample sizes, more balanced ratio of genders, lower cost, more timely data collection, reliable data, and anonymity of participants. Some of the disadvantages are: unrepresentative samples, lower response rates, financial motivation issues, limited access to certain portals, limited length of study, non-behavioral data, and lack of follow-up data. In addition, the authors share their personal experiences of using these portals and summarize previous literature researching online populations

Attitudes Toward Controlled Rest in Position (CRIP): A Gender Comparison Between Pilots and Non-Pilots

Prior studies demonstrate that controlled rest in position (CRIP) may help compensate for pilot fatigue. CRIP allows for one pilot to nap in their cockpit seat during the cruise phase of flight, provided that certain policies and procedures are followed by the other crew members during this period. The purpose of this research was to gather information from consumers and pilots on their willingness to fly if the pilots utilized CRIP. Our project employed a two-study design that manipulated both the length of the flight and the number of passengers onboard. Additionally, affect measures were collected through the use of a valid Likert scale to determine if affect had any mediating effect on the willingness to fly of participants. Study 1 was deployed to consumers while Study 2 sampled from both consumers and pilots. The findings indicated female respondents were significantly less willing to fly when CRIP was used than males, while pilots were willing to fly across all conditions. Affect was shown to be a mediating variable in all but one condition in both Study 1 and Study 2 between the types of passengers. The paper provides a discussion on these findings, identifies practical implications, and provides suggestions for future research

Physical, Cardiovascular, & Metabolic Effects of Non-Exercise Weighted Vest Training

Introduction: The high prevalence of obesity and sedentary lifestyle contribute to the growing burden of health care costs, incidence of disease, and mortality, making a lifestyle that includes regular physical activity increasingly important. Low intensity resistance training has been studied as a possible intervention to increase physical activity in inactive individuals. Purpose: To determine the effects of a weighted vest treatment (WV) on steady state VO2, O2 deficit, VO2max, body mass index (BMI), and resting blood pressure (RBP). Methods: Fourteen college age women participated in a 4 week trial and completed both pre and posttest evaluations. These evaluations included a submaximal exercise bout, a maximal graded exercise test, determination of BMI, and measurement of RBP. Seven participants wore a weighted vest, fitted with 10% of their body weight, during normal daily activities for a minimum of 10 hours a day, 5 days each week. The remaining 7 participants served as a control group. ANCOVAs, with pretest measures serving as the covariates, were conducted to determine the effect of WV on posttest responses. Results: Mean (sd) pre-test O2 deficit values were 0.64 (0.18) and 0.68 (0.18) for the control and WV groups, respectively. Mean (sd) post-test O2 deficit values were 0.62 (0.15) and 0.38 (0.17) for the control and WV groups, respectively. Results of the ANCOVA revealed a significant effect of WV on O2 deficit with O2 deficit values being lower following WV (F(1,11) = 7.30, p = 0.02). Further, WV accounted for about 40% of the change observed in posttest O2 deficit values (ηp2 = 0.40). However, no significant effect of WV was seen on steady state VO2, VO2 max, BMI, or RBP. Conclusion: WV resulted in lower O2 deficit values suggesting that it could elicit training effects related to improved aerobic function. Possible explanations for the lack of effects on other variables could be related to the limitations imposed by the relatively small sample size and trial length. Future studies designed with larger sample sizes and longer trial periods might prove more effective in evaluating the effect of WV on eliciting health related benefits

What Factors Influence the Imposter Phenomenon amongst Collegiate Flight Students?

The need for commercial airline pilots has been increasing significantly, and with the mandatory retirements projected in the next decade, the airline pilot workforce will have an injection of younger pilots. Previous research has studied the effects and prevalence of the Imposter Phenomenon (IP) in young professionals, especially graduate students, and academics. The phenomenon is particularly prevalent for female graduate students and academics. The purpose of this study is to observe the prevalence of the Imposter Phenomenon in collegiate pilots. Participants for the study are recruited from amongst collegiate flight students enrolled in a 4-year aviation university in Florida. A multiple regression analysis using backward stepwise regression will be employed to determine which factors influence the presence of Imposter Phenomenon in collegiate Part 141 pilots. 11 factors are tested as potential predictors (independent variables) in the study. These are age, gender, ethnicity, education level, total flight hours, pilot certification level, personality, measure of self-efficacy, measure self-handicapping, and perceived organizational support. The dependent variable will the participants level of Imposter Phenomenon, measured by using the 20-question validated Clance (1985) Imposter Phenomenon scale. The data collection process in currently underway, with the data analysis and results being completed and compiled by the end of 2019. This is an initial study in a line of future studies seeking to collect data from outside the collegiate pilot population, with the objective of creating a prediction model of Imposter Phenomenon within the United States pilot population

A Conceptual Model for a Universal Severity of Emergency Report (USER): An Example in Aviation

In emergency situations, it is important that information be communicated quickly, concisely, and efficiently. Breakdowns can occur when the receiver of the emergency call does not fully understand the information that the person is sending. The purpose of this paper is to present a new model for enhancing communication between the sender and receiver in emergency situations. The Universal Severity of Emergency Report (USER) is a model designed to be used in emergency situations and convey more information about the current state of the person declaring the emergency than is currently offered by emergency communication channels. USER provides three key pieces of vital information: severity of the situation, capabilities of the sender, and ability to communicate. Severity identifies the level of the emergency on a scale of 1, 2, or 3. Capabilities use the colors white, yellow, and red to indicate the current self-determined capabilities of the individual. Communicate notifies the receiver if the individual is able to communicate or is unable to communicate. This paper presents this concept in an aviation context, but USER has the potential to be used in any number of industries, including medical, military, shipping, transportation, space flight, and law enforcement

Why People Are Not Willing to Let Their Children Ride in Driverless School Buses: A Gender and Nationality Comparison

As driverless vehicles proliferate, it is possible that this technology will be applied in mass transport vehicles. School buses may be suited for autonomous operations as they follow set routes and schedules. However, a research gap exists in whether or not parents would be willing to have their children ride in autonomously operated school buses. The purpose of this study was to examine parents’ willingness to allow their child to ride in an autonomous school bus. Participant gender and nationality were also two independent variables, along with affect measures as a possible mediating variable. The research used a two-study approach. In study one, it was found that participants were less willing to have their child ride in a driverless school bus than a traditional human-operated vehicle. In study two, findings suggest a significant interaction between the type of driver, participant gender, and nationality. In general, American females were less willing than Indian females and overall, Americans were less willing than Indians in the driverless conditions. Affect was found to be a mediating variable, which suggests that emotions were playing a role in the responses of participants. The paper concludes with theoretical contributions, practical applications, and suggestions for future research

Creation of Two Valid Scales: Willingness to Fly in an Aircraft and Willingness to Pilot an Aircraft

The purpose of the current study was to develop two scales that could be used concurrently or independently to measure passenger willingness to fly (WTF), and aviator willingness to pilot (WTP), respectively. This is especially useful to determine challenges involving acceptance of new aviation technology for both pilots and passengers. There were five stages in developing the WTF scale for passengers, following Hinkin’s scale development process. Cronbach’s Alpha and Guttmann’s Split Half tests were used to confirm high internal consistency and reliability, while factor analysis was used to confirm construct validity. The scale was tested in order to confirm sensitivity to differences in actual participant willingness to fly. After developing the WTF scale for passengers, researchers made minor lexical adjustments and created the WTP scale, calculating Cronbach’s Alpha, Guttmann’s Split Half test, and factor analysis; thus, ensuring high internal consistency, reliability and validity. These two scales may help provide researchers with a better applied understanding of applications within the aviation and consumer perceptions literature and also assist with pilot training and acceptance of new aviation technology

Optimized high-throughput microRNA expression profiling provides novel biomarker assessment of clinical prostate and breast cancer biopsies

BACKGROUND: Recent studies indicate that microRNAs (miRNAs) are mechanistically involved in the development of various human malignancies, suggesting that they represent a promising new class of cancer biomarkers. However, previously reported methods for measuring miRNA expression consume large amounts of tissue, prohibiting high-throughput miRNA profiling from typically small clinical samples such as excision or core needle biopsies of breast or prostate cancer. Here we describe a novel combination of linear amplification and labeling of miRNA for highly sensitive expression microarray profiling requiring only picogram quantities of purified microRNA. RESULTS: Comparison of microarray and qRT-PCR measured miRNA levels from two different prostate cancer cell lines showed concordance between the two platforms (Pearson correlation R(2 )= 0.81); and extension of the amplification, labeling and microarray platform was successfully demonstrated using clinical core and excision biopsy samples from breast and prostate cancer patients. Unsupervised clustering analysis of the prostate biopsy microarrays separated advanced and metastatic prostate cancers from pooled normal prostatic samples and from a non-malignant precursor lesion. Unsupervised clustering of the breast cancer microarrays significantly distinguished ErbB2-positive/ER-negative, ErbB2-positive/ER-positive, and ErbB2-negative/ER-positive breast cancer phenotypes (Fisher exact test, p = 0.03); as well, supervised analysis of these microarray profiles identified distinct miRNA subsets distinguishing ErbB2-positive from ErbB2-negative and ER-positive from ER-negative breast cancers, independent of other clinically important parameters (patient age; tumor size, node status and proliferation index). CONCLUSION: In sum, these findings demonstrate that optimized high-throughput microRNA expression profiling offers novel biomarker identification from typically small clinical samples such as breast and prostate cancer biopsies

What Type of Collegiate Pilot is Likely to Experience Imposter Phenomenon?

Background: Imposter Syndrome (IS), also called Imposter Phenomenon (IP), has been studied in a variety of paradigms over the past few decades. However, IP is not a well-researched concept in the field of aviation, and no studies that we know of have examined this phenomenon with student pilots. Method: Two hundred and forty-one student pilots were interviewed from two southeastern universities with flight schools. Participants were asked a series of questions about demographics, flight training, personality measures, self-efficacy, self-handicapping, and perceived organizational support. In addition, they responded to the Clance IP scale. Results: A regression equation was created from the first dataset and tested for model fit with a second dataset. Four factors were found to be significant, including measures of self-handicapping, measures of self-efficacy, income, and the type of flight school, accounting for approximately 40% of the variance in the data. Model fit was strong, providing future researchers with a predictive model of IP for student pilots. Conclusion: These findings show that IP is prevalent in student pilots and correlates with self-handicapping. This is a concern that should be addressed in aviation programs
