Open Educational Resources In The United States: Insights From University Foreign Language Directors, Joshua J. Thoms, Becky L. Thoms
Open Educational Resources In The United States: Insights From University Foreign Language Directors, Joshua J. Thoms, Becky L. Thoms
Joshua J. Thoms
This study reports the results of a survey completed by 155 university foreign language (FL) directors in the United States (US) during Fall 2012. Survey respondents come from a variety of institutions and direct a range of FL programs. The objectives of the study are to (a) determine what FL directors know about open educational resources (OER), (b) understand respondents’ perceived benefits and challenges of using OER, and (c) determine what resources and support are critical to establish or expand the use of OER in FL courses in the US. Results indicate that while 66% of FL directors do not …
Birkhoff Theorems In General Relativity, Charles G. Torre
Birkhoff Theorems In General Relativity, Charles G. Torre
Charles G. Torre
In the following Maple worksheet I demonstrate three versions of Birkhoff's theorem, which is a characterization of spherically symmetric solutions of the Einstein equations. The three versions considered here correspond to taking the "Einstein equations" to be: (1) the vacuum Einstein equations; (2) the Einstein equations with a cosmological constant (3) the Einstein-Maxwell equations.

Women In Business Leadership: A Comparative Study Of Countries In The Gulf Arab States, Susan R. Madsen, Linzi Kemp, James Davis
Susan R. Madsen
The purpose of this study is to investigate the status of women in leadership positions (senior executive and management roles) in private companies within the countries of the Gulf Cooperation Council (i.e., Kingdom of Bahrain, State of Kuwait, Kingdom of Saudi Arabia, Sultanate of Oman, State of Qatar, and United Arab Emirates). Henceforth in this article we refer to the countries collectively as either the Gulf Arab states or the GCC countries, and the countries by their common or shortened names (e.g., Bahrain, UAE). The study explores where women are located within the organizations (e.g., as board members, chief officers, …

Advancing Research On Women And Leadership: Developing An Hrd Scholarly Agenda, Susan R. Madsen, Julia Storberg-Walker, Kristina Natt Och Dag
Susan R. Madsen
Clearly, the topic of developing leaders is of utmost importance in all contexts and it is particularly important for the HRD discipline: over 1,400 journal articles in AHRD journals have the word ‘leadership’ as one of their subject terms. Almost monthly the front cover of the Harvard Business Review has ‘leadership’ boldly displayed, either as the main article or as a supporting news brief. Scholarly research abounds, and there are many leadership frameworks, models, and theories contributing to the quantity of research articles. Unfortunately, however, the diversity of ideas and the explosion of interest has generally not focused on an …

Measuring The Value Of Plastic And Reusable Grocery Bags, Jarod Dunn, Arthur J. Caplan, Ryan Bosworth
Measuring The Value Of Plastic And Reusable Grocery Bags, Jarod Dunn, Arthur J. Caplan, Ryan Bosworth
Arthur J. Caplan
Using data from an online survey of grocery store customers in Logan, Utah, we estimate the marginal effects on willingness to pay (WTP) for continued use of plastic grocery bags, and the marginal effects on willingness to accept (WTA) for switching to reusable grocery bags. We find both non-parametric and parametric evidence suggesting that individuals respond quite dramatically to moderate plastic-bag tax rates and reusable-bag subsidy rates. All else equal, older and lower-to-middle income individuals, as well as larger-sized households, are more likely to switch to using reusable bags exclusively when faced with a tax on plastic bags. Lower-to-middle income …
Measuring The Surplus Of Superficiality: The Case Of Dented Bumper Repair, Arthur Caplan
Measuring The Surplus Of Superficiality: The Case Of Dented Bumper Repair, Arthur Caplan
Arthur J. Caplan
This article uses data from a survey administered to 400 automobile owners in northern Utah to estimate willingness-to-pay (WTP) for removal of a superficial dent in the bumper of a typical owner’s vehicle. A unique set of controls are used to estimate the determinants of WTP for this particular manifestation of superficiality. Both parametric and nonparametric measures of meanWTP are also derived. To the extent that a driver’s demand for superficiality represents a market failure, e.g., due to imperfect information, or, in a normative sense, the influence of wasteful social norms, our welfare measures represent estimates of the potential social …
Playing With A Robot To Learn English Vocabulary, Yanghee Kim
Playing With A Robot To Learn English Vocabulary, Yanghee Kim
Yanghee Kim
A robot-based English curriculum called The Missing Code has been developed to teach English vocabulary to young children whose home language is one other than English. Guided by theories in children’s learning and motivation, the curriculum was designed to be developmentally appropriate and engaging for children that were 3-5 years old, carefully balancing the familiar and the new. The development process was characterized by iterative cycles of initial design, user testing, and refinement. Through multiple observations of child-robot play in situ, it was noted that children easily learned how to interact with the robot and showed sustained interest and engagement …

Promoting And Evaluating Online Learner-Instructor Relationships, Yanghee Kim, R Burdo, T Chen
Yanghee Kim
Emotions that a learner brings to the learning context can influence engagement, self-regulation, and achievement. Recently, researchers have called for examination on the impact of learner emotions in online learning environments. This study examines how to incorporate learner/instructor relationship aspects in online instruction and promote affective relationships with the learners. Participants enrolled in a college statistics course took a weeklong video-based module covering Normal Distribution. Learner attitudes, learner self-efficacy, learner/instructor relationship, and learning gains were evaluated. The relationship building strategies were found to have positive impacts on learner attitudes and self-efficacy. The inclusion of the relationship building strategies, however, did …

Instructional Design Affects The Efficacy Of Simulation-Based Training In Central Venous Catheterization, David F. Feldon
Instructional Design Affects The Efficacy Of Simulation-Based Training In Central Venous Catheterization, David F. Feldon
David F Feldon
Background: Simulation-based learning is a common educational tool in healthcare training and frequently employs instructional designs based on Experiential Learning Theory (ELT). However, little research explores the effectiveness and efficiency of different instructional design methodologies appropriate for simulations. This study compares two instructional design models, ELT and Guided Experiential Learning (GEL), to determine which is more effective for training the central venous catheterization (CVC) procedure. Methods: Using a quasi-experimental randomized block design, nurse anesthetists completed training under one of the two instructional design models. Performance was assessed using a checklist of CVC performance, pass rates, and critical action errors. Results: …

Faculty Perceptions Of Common Challenges Encountered By Novice Doctoral Writers, Michelle Maher, David F. Feldon, Briana Timmerman, Jie Chao
David F Feldon
Although learning to write for publication is an important outcome of doctoral education, it has received surprisingly little scholarly attention. Within a socialization and supervisor pedagogy framework, this study uses narratives of faculty who regularly write with their doctoral students for publication to expose challenges students commonly encounter in the writing process. Common challenges include international students’ ‘writing problem’, misconstruing the nature of disciplinary writing and not realizing that ‘public’ is part of publication.
An Ecological View Of Whole-Class Discussions In A Second Language Literature Classroom: Teacher Reformulations As Affordances For Learning, Joshua J. Thoms
An Ecological View Of Whole-Class Discussions In A Second Language Literature Classroom: Teacher Reformulations As Affordances For Learning, Joshua J. Thoms
Joshua J. Thoms
This article analyzes whole-class discussions between a teacher and her students in a Latin American Colonial literature course at the college level. The study is theoretical–exploratory in nature in that it (a) articulates theoretical assumptions inherent in an ecological perspective on second language learning and teaching, and (b) attempts to operationalize the affordance construct (van Lier, 2000, 2004) in the context of a second language (L2) literature classroom. The study’s findings underscore the importance of teacher reformulations when engaging students in whole-class discussions, as well as students’ engagement with and awareness of the unfolding talk. Furthermore, how the teacher dynamically …
Benchmarking An Optimal Pattern Of Pollution Trading: The Case Of Cub River, Utah, Arthur Caplan, Yuya Sasaki
Benchmarking An Optimal Pattern Of Pollution Trading: The Case Of Cub River, Utah, Arthur Caplan, Yuya Sasaki
Arthur J. Caplan
This paper employs a recently developed, dynamic trading algorithm to establish a benchmark pattern of trade for a potential water quality trading (WQT) market in the Cub River sub-basin of Utah; a market that would ultimately include both point and nonpoint sources. The algorithm accounts for three complications that naturally arise in trading scenarios: (1) combinatorial matching of traders, (2) trader heterogeneity, and (3) discreteness in abatement technology. The algorithm establishes as detailed a reduced-cost benchmark as possible for the sub-basin by distinguishing a specific pattern of trade among would-be market participants. As such, the algorithm provides a benchmark against …

Cultural Variation In Life Phases., David F. Lancy, M. Annette Grove
David Lancy
The knowledge base in the study of human development is built primarily from work with children from the modern, global, post-industrial population. This population is unrepresentative in many respects, not least in that childhood and adolescence is dominated by the experience of formal schooling—an experience missing from the lives of most of the world’s children until very recently. This entry will examine child development from the perspective of pre-modern societies as described in the ethnographic, archaeological and historic records. Specifically, we will review material indicative of cultural or indigenous models of development, phases and phase transitions, in particular.

The emphasis on improving writing instruction, especially the writing of non-narrative texts, may lead some teachers to seek effective ways to teach students. The IMSCI model, a scaffolded model for writing instruction, is useful for planning effective instruction. This article describes a research project conducted in a 4th grade classroom emphasizing the combined benefits of scaffolded instruction and genre study and testing scaffolded persuasive writing lessons based on the IMSCI model. Researchers wrote lesson plans using the IMSCI model as the underlying structure and tied the lessons to science objectives for fourth grade. Teachers implemented the lessons in their classrooms …

Justice And Immigrant Latino Recreation Geography In Cache Valley, Utah, Jodie Madsen, Claudia Radel, Joanna Endter-Wada
Justice And Immigrant Latino Recreation Geography In Cache Valley, Utah, Jodie Madsen, Claudia Radel, Joanna Endter-Wada
Joanna Endter-Wada
Latinos are the largest U.S. non-mainstreamed ethnic group, and social and environmental justice considerations dictate recreation professionals and researchers meet their recreation needs. This study reconceptualizes this diverse group’s recreation patterns, looking at where immigrant Latino individuals in Cache Valley, Utah do recreate rather than where they do not. Through qualitative interviews and interactive mapping, thirty participants discussed what recreation means to them and explained their recreation site choices. Findings suggest that recreation as an activity done outside the home, for fun with others, leads participants to seek spaces with certain characteristics. Reconceiving recreation more broadly and framing it from …
Native And Domestic Browsers And Grazers Reduce Fuels, Fire Temperatures, And Acacia-Ant Mortality In An African Savanna, Kari E. Veblen
Native And Domestic Browsers And Grazers Reduce Fuels, Fire Temperatures, And Acacia-Ant Mortality In An African Savanna, Kari E. Veblen
Kari E. Veblen
Despite the importance of fire and herbivory in structuring savanna systems, few replicated experiments have examined the interactive effects of herbivory and fire on plant dynamics. In addition, the effects of fire on associated ant-tree mutualisms have been largely unexplored. We carried out small controlled burns in each of 18 herbivore treatment plots of the Kenya Long-term Exclosure Experiment (KLEE), where experimentally excluding elephants has resulted in 42% greater tree densities. The KLEE design includes six different herbivore treatments that allowed us to examine how different combinations of megaherbivore wildlife, mesoherbivore wildlife, and cattle affect fire temperatures and subsequent loss …
Monitoring Of Livestock Grazing Effects On Bureau Of Land Management Land, Kari E. Veblen
Monitoring Of Livestock Grazing Effects On Bureau Of Land Management Land, Kari E. Veblen
Kari E. Veblen
Public land management agencies, such as the Bureau of Land Management (BLM), are charged with managing rangelands throughout the Western United States for multiple uses such as livestock grazing and conservation of sensitive species and their habitats. Monitoring of condition and trends of these rangelands, particularly with respect to effects of livestock grazing, provide critical information for effective management of these multi-use landscapes. We therefore investigated the availability of livestock grazing-related quantitative monitoring data and qualitative region-specific Land Health Standards (LHS) data across BLM grazing allotments in the Western United States. We then queried university and federal rangeland science experts …
