Residential Real Estate Prices: A Room with a View

This article is the winner of the Real Estate Broker / Agency manuscript prize (sponsored by the Center for the Study of Real Estate Brokerage/ Agency at Cleveland State University) presented at the 2001 American Real Estate Society Annual Meeting. This study examines the effect that a view of Lake Erie has on the value of a home. Unlike previous studies, the current investigation is able to successfully control for view. That is, because of the unique building codes of lakefront homes in this sample, homes analyzed either do or do not have a view. Moreover, transaction-based home prices are used which is an improvement over previous studies that rely on appraisal-based data. The results indicate that square footage and lot size also significantly affect a home’s value. More importantly, having this very desirable view adds $256,544.72 (an 89.9% premium) to the value of the home.

Real Estate Returns and Inflation: An Added Variable Approach

This study analyses the inflation hedging effectiveness of residential real estate over the 1969-94 period. The results indicate that residential real estate is a significant hedge against both expected and unexpected inflation. These results indicate that since financial assets are not good inflation hedges in periods of high unexpected inflation, including real estate in a portfolio should decrease the variance of the portfolio returns. These results were made possible by the use of the Added Variable Regression Method (AVRM), a measure which has yet to be employed in this context. There are nine variables included in the AVRM framework which are also found to have significant explanatory power relative to residential real estate returns.

Comment on `Hawking radiation from fluctuating black holes'

Takahashi & Soda (2010 Class. Quantum Grav. v27 p175008, arXiv:1005.0286) have recently considered the effect (at lowest non-trivial order) of dynamical, quantized gravitational fluctuations on the spectrum of scalar Hawking radiation from a collapsing Schwarzschild black hole. However, due to an unfortunate choice of gauge, the dominant (even divergent) contribution to the coefficient of the spectrum correction that they identify is a pure gauge artifact. I summarize the logic of their calculation, comment on the divergences encountered in its course and comment on how they could be eliminated, and thus the calculation be completed.Comment: 12 pages, 1 fig; feynmp, amsref

TikTok, CFIUS, And The Splinternet

This note will discuss the role that the Committee on Foreign Investment in the United States (“CFIUS” or “the Committee”) has played in foreign relations and how it contributes to the balkanization of the internet today. The Committee is an interagency body that reviews foreign investments for potential national security threats. Recently, CFIUS has been in the spotlight for its role in the sale of TikTok, a cellphone app owned by a popular Chinese corporation, ByteDance. While much of CFIUS’ review in the past has been focused on Chinese-owned corporations, there is much debate about whether or not countries should opt to sever the internet due to political, social, or economic pressures. Through the example of TikTok, this note will analyze what the right balance is between protecting national security and maintaining a united interne

Detailed Visual Cortical Responses Generated by Retinal Sheet Transplants in Rats with Severe Retinal Degeneration.

To combat retinal degeneration, healthy fetal retinal sheets have been successfully transplanted into both rodent models and humans, with synaptic connectivity between transplant and degenerated host retina having been confirmed. In rodent studies, transplants have been shown to restore responses to flashes of light in a region of the superior colliculus corresponding to the location of the transplant in the host retina. To determine the quality and detail of visual information provided by the transplant, visual responsivity was studied here at the level of visual cortex where higher visual perception is processed. For our model, we used the transgenic Rho-S334ter line-3 rat (both sexes), which loses photoreceptors at an early age and is effectively blind at postnatal day 30. These rats received fetal retinal sheet transplants in one eye between 24 and 40 d of age. Three to 10 months following surgery, visually responsive neurons were found in regions of primary visual cortex matching the transplanted region of the retina that were as highly selective as normal rat to stimulus orientation, size, contrast, and spatial and temporal frequencies. Conversely, we found that selective response properties were largely absent in nontransplanted line-3 rats. Our data show that fetal retinal sheet transplants can result in remarkably normal visual function in visual cortex of rats with a degenerated host retina and represents a critical step toward developing an effective remedy for the visually impaired human population.SIGNIFICANCE STATEMENT Age-related macular degeneration and retinitis pigmentosa lead to profound vision loss in millions of people worldwide. Many patients lose both retinal pigment epithelium and photoreceptors. Hence, there is a great demand for the development of efficient techniques that allow for long-term vision restoration. In this study, we transplanted dissected fetal retinal sheets, which can differentiate into photoreceptors and integrate with the host retina of rats with severe retinal degeneration. Remarkably, we show that transplants generated visual responses in cortex similar in quality to normal rats. Furthermore, transplants preserved connectivity within visual cortex and the retinal relay from the lateral geniculate nucleus to visual cortex, supporting their potential application in curing vision loss associated with retinal degeneration

On the Structure of the Observable Algebra of QCD on the Lattice

The structure of the observable algebra ${\mathfrak O}_{\Lambda}$ of lattice QCD in the Hamiltonian approach is investigated. As was shown earlier, ${\mathfrak O}_{\Lambda}$ is isomorphic to the tensor product of a gluonic $C^{*}$-subalgebra, built from gauge fields and a hadronic subalgebra constructed from gauge invariant combinations of quark fields. The gluonic component is isomorphic to a standard CCR algebra over the group manifold SU(3). The structure of the hadronic part, as presented in terms of a number of generators and relations, is studied in detail. It is shown that its irreducible representations are classified by triality. Using this, it is proved that the hadronic algebra is isomorphic to the commutant of the triality operator in the enveloping algebra of the Lie super algebra ${\rm sl(1/n)}$ (factorized by a certain ideal).Comment: 33 page

Manifestation of a sellar hemangioblastoma due to pituitary apoplexy: a case report

Introduction Hemangioblastomas are rare, benign tumors occurring in any part of the nervous system. Most are found as sporadic tumors in the cerebellum or spinal cord. However, these neoplasms are also associated with von Hippel-Lindau disease. We report a rare case of a sporadic sellar hemangioblastoma that became symptomatic due to pituitary apoplexy. Case presentation An 80-year-old, otherwise healthy Caucasian woman presented to our facility with severe headache attacks, hypocortisolism and blurred vision. A magnetic resonance imaging scan showed an acute hemorrhage of a known, stable and asymptomatic sellar mass lesion with chiasmatic compression accounting for our patient's acute visual impairment. The tumor was resected by a transnasal, transsphenoidal approach and histological examination revealed a capillary hemangioblastoma (World Health Organization grade I). Our patient recovered well and substitutional therapy was started for panhypopituitarism. A follow-up magnetic resonance imaging scan performed 16 months postoperatively showed good chiasmatic decompression with no tumor recurrence. Conclusions A review of the literature confirmed supratentorial locations of hemangioblastomas to be very unusual, especially within the sellar region. However, intrasellar hemangioblastoma must be considered in the differential diagnosis of pituitary apoplexy

Topological Charge Correlators, Spectral Bounds, and Contact Terms

The structure of topological charge fluctuations in the QCD vacuum is strongly restricted by the spectral negativity of the Euclidean 2-point correlator for $x\neq 0$ and the presence of a positive contact term. Some examples are considered which illustrate the physical origin of these properties.Comment: Lattice 2002 Conference Proceeding
