Factors Affecting Adoption and Diffusion of Distance Education Among Health Education Faculty

Background: In the past decade, distance education enrollment has become more common in colleges and universities, increasing from 1.6 million students in 1998 to an estimated 6.7 million in 2012. The purpose of this study was to identify which constructs in Rogers\u27 (2003) diffusion of innovation theory are more likely to contribute to adoption and diffusion of distance education in health education. Health education instructors and faculty can use the information obtained from the results of this study if they want to implement distance education. Methods: A quantitative, cross-sectional, descriptive, and correlational survey design was used in this study. An instrument designed to measure constructs and factors affecting the adoption and diffusion of distance education in health education were developed for the study. Health educators employed by health education departments listed in the AAHE (2011) Directory (N=498) were contacted by email and asked to participate in this study. The survey was distributed through SurveyMonkeyTM survey software that was activated December 2012 - January 2013. Results and Conclusions: A total of 245 health education faculty completed the instrument, but 21 participants were omitted because they did not complete at least 95% of the survey instrument. A total of 224 survey instruments were retained and included in the analysis, providing a 44.9% response rate. Based on the Pearsons correlation and multiple linear regression it can be concluded that the likelihood of distance education adoption by health education faculty is highly dependent on the communication channels and characteristics of the innovation (distance education) constructs of the diffusion of innovation theory. There was a large majority of participants in the early majority adopter category and this is because of two reasons. The first reason is that participants had not decided whether to accept or reject distance education. The other reason is that distance education is a relatively new innovation and it has not fully diffused through the health education profession. Experience with distance education was not shown to increase the likelihood of distance education adoption because the majority of participants have not yet decided whether to accept or reject distance education. The social system construct was the least predictive of distance education adoption. If distance education has not yet fully diffused through the health education profession then it is hard for the social system to impact the likelihood of distance education adoption

Retrospective Evaluation of High School Primary Physical Activities and Adulthood Physical Activity Need Satisfaction

Presumably, individuals are taught skills throughout their primary education that are required to live a healthy lifestyle throughout the lifespan. The primary purpose of this study was to assess adult psycho- logical need satisfaction in relation to high school participation. Participation included university employees and students of two mid-sized universities and members of a state health organization. Participants (n = 512) completed the Psychological Need Satisfaction in Exercise (PNSE) and the International Physical Activity Questionnaire (IPAQ). The current study found modest associations between measured motivation constructs on physical activity levels. Standardized coefficients report competence and autonomy had a significant effect on physical activity in predicting adult physical activity levels. Results of this study provide insight into the determinants underlying the development of physical activity tendencies in adults and suggest high school physical education and sport participation have an equal influence on adult physical activity levels

Adolescent Healthcare Brokering: Prevalence, Experience, Impact, and Opportunities

BACKGROUND: Limited health literacy disproportionately affects those with limited English proficiency (LEP). Parents with LEP might rely on their adolescent children to interpret health information. We call this adolescent health care brokering. This study uncovers the prevalence of brokering, kinds of tasks, emotional and academic impact, and desired support. METHODS: We invited 165 students from health classes (in a community in which 29.8% are foreign-born and 53.4% speak another language at home) to complete a survey. We used IBM SPSS to calculate descriptive statistics. RESULTS: Of the 159 who received parental consent and assented, 54.1% (n=86) assist with healthcare tasks. When brokering, 80.2% (n=69) translate. Most common tasks were talking to a doctor, reading prescriptions, and searching on the Internet. Participants were most confident reading prescriptions and talking to a doctor and least confident finding healthcare services. Among brokers, 29.1% (n=24) missed school; 33.7% did not complete homework. They most wanted to learn about filling out insurance forms and talking to doctors. CONCLUSIONS: Despite assurances that children are not permitted to interpret, adolescents are acting as healthcare brokers. The impact can be academic and emotional. Findings indicate a need for further research and support for adolescents who want to learn about healthcare tasks

The Adolescent Health Care Broker – Adolescents Interpreting for Family Members and Themselves in Health Care

Parents with limited English proficiency might rely on their adolescent children to interpret health information. We call this adolescent healthcare brokering. Using a mixed-methods, transformative research approach rooted in grounded theory, we sought to answer these questions: (a) “What is happening? What are people doing?” and (b) “What do these stories indicate? What might they suggest about social justice?” High school students from a community in which 53.4% speak another language at home were invited to participate in a survey and focus groups. Of 238 survey participants, 57.5% (n=137) indicated they assisted with healthcare tasks. When doing so, 81.7% (n=112) translated. Common tasks were reading prescriptions and talking to doctors. While some participants cited negative emotions associated with brokering, the net emotion was positive. Focus groups (n=11) revealed that tasks varied broadly in complexity and type, emotional experiences were dichotomous, and access to interpreting services and other supports was inconsistent

Weyl's Lagrangian in teleparallel form

The main result of the paper is a new representation for the Weyl Lagrangian (massless Dirac Lagrangian). As the dynamical variable we use the coframe, i.e. an orthonormal tetrad of covector fields. We write down a simple Lagrangian - wedge product of axial torsion with a lightlike element of the coframe - and show that this gives the Weyl Lagrangian up to a nonlinear change of dynamical variable. The advantage of our approach is that it does not require the use of spinors, Pauli matrices or covariant differentiation. The only geometric concepts we use are those of a metric, differential form, wedge product and exterior derivative. Our result assigns a variational meaning to the tetrad representation of the Weyl equation suggested by J. B. Griffiths and R. A. Newing

An Examination of Estimated BMI and Perceived Wellness among Students at a Midsized Midwest University

Health is complex and the perception of individual wellness can be influenced by various factors. Students at a Midwestern university estimated their BMI, completed the Perceived Wellness Survey, and had their BMI calculated. Measured BMI was significantly higher than estimated [F(2,155) = 62.03, p = 0.001]. Associations existed between the measured constructs of psychological (r = -0.231; p = 0.004), spiritual (r = 0.248; p = 0.002), and estimated BMI. Data indicates that perceived body composition is related to wellness. False perception of body composition could lead to wellness deficiencies

Approaches for advancing scientific understanding of macrosystems

The emergence of macrosystems ecology (MSE), which focuses on regional- to continental-scale ecological patterns and processes, builds upon a history of long-term and broad-scale studies in ecology. Scientists face the difficulty of integrating the many elements that make up macrosystems, which consist of hierarchical processes at interacting spatial and temporal scales. Researchers must also identify the most relevant scales and variables to be considered, the required data resources, and the appropriate study design to provide the proper inferences. The large volumes of multi-thematic data often associated with macrosystem studies typically require validation, standardization, and assimilation. Finally, analytical approaches need to describe how cross-scale and hierarchical dynamics and interactions relate to macroscale phenomena. Here, we elaborate on some key methodological challenges of MSE research and discuss existing and novel approaches to meet them

Andrew Melville, sacred chronology and world history: the Carmina Danielis 9 and the Antichristus

The accepted view of the ecclesiastical reformer Andrew Melville (1545–1622) as the dynamic leader of the Presbyterian movement in Jacobean Scotland has been severely eroded in recent years, with particular criticism of the actual importance of his contribution to the Kirk and to Scottish higher education. While this reductionism has been necessary, it has resulted in an inversion of the overwhelmingly positive traditional image of Melville, and does not give us a rounded assessment of his life and works. This article attempts to partially redress this balance by looking at a neglected aspect of Melville's Latin writings, which showcase his talents as a humanist intellectual and biblical commentator. It focuses on two long poems that are both commentaries and paraphrases of Daniel and Revelation: the Carmina Danielis and the Antichristus. Through these poems, we see how Melville engaged with two problems exercising reformed theologians across Europe: the dating of key biblical events and the historicised meaning of prophecies within these texts. We also find evidence that Melville read widely among both contemporary and ancient commentators on both these issues

Sulfur geochemistry of hydrothermal waters in Yellowstone National Park, Wyoming, USA. III. An anion-exchange resin technique for sampling and preservation of sulfoxyanions in natural waters

A sampling protocol for the retention, extraction, and analysis of sulfoxyanions in hydrothermal waters has been developed in the laboratory and tested at Yellowstone National Park and Green Lake, NY. Initial laboratory testing of the anion-exchange resin Bio-Rad™ AG1-X8 indicated that the resin was well suited for the sampling, preservation, and extraction of sulfate and thiosulfate. Synthetic solutions containing sulfate and thiosulfate were passed through AG1-X8 resin columns and eluted with 1 and 3 M KCl, respectively. Recovery ranged from 89 to 100%. Comparison of results for water samples collected from five pools in Yellowstone National Park between on-site 1C analysis (U.S. Geological Survey mobile lab) and IC analysis of resin-stored sample at SUNY-Stony Brook indicates 96 to 100% agreement for three pools (Cinder, Cistern, and an unnamed pool near Cistern) and 76 and 63% agreement for two pools (Sulfur Dust and Frying Pan). Attempts to extract polythionates from the AG1-X8 resin were made using HCl solutions, but were unsuccessful. Bio-Rad™ AG2-X8, an anion-exchange resin with weaker binding sites than the AG1-X8 resin, is better suited for polythionate extraction. Sulfate and thiosulfate extraction with this resin has been accomplished with KCl solutions of 0.1 and 0.5 M, respectively. Trithionate and tetrathionate can be extracted with 4 M KCl. Higher polythionates can be extracted with 9 M hydrochloric acid. Polythionate concentrations can then be determined directly using ion chromatographic methods, and laboratory results indicate recovery of up to 90% for synthetic polythionate solutions using AG2-X8 resin columns
