Global Real Estate Markets - Cycles and Fundamentals
The correlations among international real estate markets are surprisingly high, given the degree to which they are segmented. While industrial, office and retail properties exist all around the world, they are not economic substitutes because of locational specificity. In addition, the broad securitization of real estate property companies has, until recently, lagged that of other types of companies. Never-the-less, international property returns move together in dramatic fashion. In this paper, we use eleven years of global property returns to explore the factors influencing this co-movement. We attribute a substantial amount of the correlation across world property markets to the effects of changes in GNP, suggesting that real estate is a bet on fundamental economic variables which are correlated across countries. A decomposition shows that a local production factor is more important in some countries than in others.
Working Memory Deficits in Students with ADHD: Implications for Developing Curriculum on Introductory Trigonometric Functions and the Unit Circle
Attention Deficit Hyperactivity Disorder (ADHD) is one of the most prevalently diagnosed disorders in children in the United States today (Zentall, 2007, p. 219; American Psychiatrica Association, 2000; Faraone, Sergant, Gillberg & Bierderman, 2003). “Teachers report that they are unprepared to work with [students with ADHD] and only those educators who have experience with students with ADHD or who have education about them [are] willing to make instructional changes” (Zentall & Javorsky, 2007, p.78; Reid, Vasa, Maag & Wright, 1994). The relatively new implementation of the Common Core State Standards (CCSS) has brought on “rigorous grade-level expectations in the area of mathematics” (Common Core State Standards Initiative, 2014, p.1) According to the guidelines of CCSS, students identified as having a disability under the Individuals with Disabilities Education Act (IDEA) will also be held to the same high standards as all students in the general classroom. The Cognitive Load Theory (CLT) lays a foundation for the following curriculum. The purpose of this curriculum project is to develop a unit in the field of introductory trigonometric functions and the unit circle that addresses specific needs of students with ADHD while still holding the high expectations implemented by the CCSS
Mortgage Default Risk and Real Estate Prices: The Use of Index-Based Futures and Options in Real Estate
Evidence is shown, using US foreclosure data by state 1975-93, that periods of high default rates on home mortgages strongly tend to follow real estate price declines or interruptions in real estate price increase. The relation between price decline and foreclosure rates is modelled using a distributed lag. Using this model, holders of residential mortgage portfolios could hedge some of the risk of default by taking positions in futures or options markets for residential real estate prices, were such markets to be established.
Verification of the Convection-Allowing Ensemble System over the Hindu Kush Himalaya Region During the 2018 and 2019 Pre-Monsoon Severe Thunderstorm Seasons
Some of the most intense thunderstorms on the planet occur in the Hindu Kush Himalaya (HKH) region of South-Central Asia. NASA/SERVIR Applied Sciences Team competitive project to develop capacity of severe thunderstorm monitoring and forecasting tool for HKH. Project Goal: Use [NASA] modeling and remote-sensing assets to build early warning capabilities and facilitate timely disaster response for high impact weather events in the HKH region. Specific objectives: 1. Prototype and transition High-Impact Weather Assessment Toolkit (HIWAT) 2. Jointly develop HIWAT capabilities & training with SERVIRs hub in Kathmandu, Nepal: International Centre for Integrated Mountain Development (ICIMOD) 3. Demonstrate capacity in end-user environment 4. Transition HIWAT system to ICIMOD for future maintenance
Mechanical regulation of chondrogenesis.
Mechanical factors play a crucial role in the development of articular cartilage in vivo. In this regard, tissue engineers have sought to leverage native mechanotransduction pathways to enhance in vitro stem cell-based cartilage repair strategies. However, a thorough understanding of how individual mechanical factors influence stem cell fate is needed to predictably and effectively utilize this strategy of mechanically-induced chondrogenesis. This article summarizes some of the latest findings on mechanically stimulated chondrogenesis, highlighting several new areas of interest, such as the effects of mechanical stimulation on matrix maintenance and terminal differentiation, as well as the use of multifactorial bioreactors. Additionally, the roles of individual biophysical factors, such as hydrostatic or osmotic pressure, are examined in light of their potential to induce mesenchymal stem cell chondrogenesis. An improved understanding of biomechanically-driven tissue development and maturation of stem cell-based cartilage replacements will hopefully lead to the development of cell-based therapies for cartilage degeneration and disease

Student Attitudes Towards Distance Education: A Comparison of Views in Australia and the US
There have been frequent and repeated calls for empirical studies examining distance learning. This paper presents the results of a study that compares US and Australian post-graduate students involved in similar courses. It finds marked differences in perceptions between those involved in distance education and those studying by more traditional means. Differences between the two nationalities are also noted. The paper calls for further work in this area and invites a series of collaborative studies
