- Developing Supplemental Instructional Videos for Construction Management EducationBarnes, Andrew F.; McCoy, Andrew P.; Warnick, Quinn (MDPI, 2023-09-28)Technological advancements and lower production costs since the mid-1990s have dramatically improved opportunities for instructors to tailor self-made instructional videos for their students. However, video production technology has outpaced the development of educational theory, causing instructional videos to consistently fall short of their pedagogical potential. Responding to these shortcomings, scholars from various backgrounds have started publishing guidelines to help practitioners as they develop instructional videos for their respective fields. Using a rapid literature review, this article contributes to this ongoing effort by synthesizing theory-based, best-practice guidelines for a specific subcategory of educational videos called supplemental instructional videos (SIVs). SIVs are different from other types of instructional videos in that they are used to support and magnify other learning methods, mediums, and materials rather than substitute for them. Bringing the best-practice guidelines synthesized in this paper immediately into application, they were used to inform the production of SIVs for an undergraduate course that was held in the Building Construction Department of a major public university in the United States during the Spring 2020 semester. The methods used in the production of the SIV guidelines were systematically documented during the course for future researchers and practitioners to learn and build from.
- Exploring the Survival Mechanisms of Short-Term Rentals in Virginia: A Comparative Analysis of Rural versus Non-Rural MarketsChoi, Seungbee; Won, Jongho (MDPI, 2023-08-21)This study provides a comprehensive analysis of the survival mechanisms of STRs in Virginia, particularly focusing on rural versus non-rural markets. Utilizing data from AirDNA, we observe 16,852 active listings from 2018 to 2022. The study identifies the influence of various factors on STR longevity, including unit type, location, and the number of bedrooms. It is a unique attempt to bridge the gap in understanding the dynamics of short-term rentals (STRs) in rural and urban contexts. Our findings reveal differences in the survival patterns of STRs in rural versus non-rural markets. In particular, rural STRs exhibit higher survival probabilities compared to their non-rural counterparts. Furthermore, Full-Time STRs, which are primarily dedicated to short-term rentals, show significantly higher survival probabilities than Occasional STRs, regardless of their location. These findings serve as critical inputs for stakeholders involved in policymaking, regulation, and industry strategies. By highlighting the distinctive dynamics of rural and urban STR markets, we underscore the need for context-specific regulations that can balance the economic benefits of STRs with the preservation of local housing options.
- HIEE Energy Burden Brief 2022Jones O'Brien, Melissa (2022-05-12)Approximately 718,684 Virginia households pay more than six percent of their household income for electricity and other fuel costs. About 30 percent of these households, 210,344, have low incomes and among the highest energy costs (top 25%) for their region. These households are excellent candidates for energy efficiency interventions including weatherization and home energy upgrades, mobile home replacement, and/or opportunities to move to a more energy efficient and comfortable residence. Efforts to provide these households with more energy efficient residences would achieve dual goals of freeing up household income to meet other needs and conserving costly energy resources. VCHR analyzed energy costs, energy burden, and household characteristics that contribute to high energy costs and energy burden to prepare estimates of where households with high energy costs live. Though there are households with high energy costs and energy burdens throughout the state, these estimates highlight where large numbers of households with high energy costs are concentrated and where public investments are likely to have the greatest impact for individuals and communities.
- Effects of Top-Down Balanced Development Strategies on Regional Balance: Evidence from Public Big Data in KoreaYoo, Yejin; Choi, Seungbee (MDPI, 2022-12-05)The rapid economic growth of Korea was accompanied by the side effect of disproportionate growth between regions. The central government has implemented balanced development strategies by enacting the Special Act on Balanced National Development. For example, central administrative institutions were relocated to Sejong-si, which was built as the administrative capital. This study examines whether the top-down strategy promoted balanced growth between regions using public big data. We use various indicators to pay attention to not only quantitative growth, such as population size and economic growth, but also qualitative growth, such as life satisfaction. The results show that, despite the government’s efforts, the population was concentrated in the major metropolitan areas and the economic gap between regions did not narrow. While metropolitan areas achieved steady growth based on the preemption of spatial competitiveness, non-metropolitan areas did not take advantage of more investment from government. However, it shows a significant increase in job creation in Sejong-si, suggesting it is more efficient to move institutions in groups than to completely disperse public institutions in the balanced development strategy. In terms of the quality of life, Sejong-si had the lowest personal life satisfaction and local life satisfaction, indicating that the top-down strategy has failed to manage the quality of life. We propose that promoting a compact city with multiple functions in the non-metropolitan areas will help balance development. To achieve a better quality of life, centralized power should be transferred to local governments, and policies should be built based on communication with local residents. Innovative and sustainable policies that efficiently utilize the uniqueness and potential of the region are needed for balanced growth.
