    Corporate Real Estate Research within the Academy

    This study discusses the uniqueness and importance of corporate real estate asset management and distinguishes it from third party real estate investment management. A decline in corporate real estate research within the academy from 1995 through 1998 is documented and contrasted with the increasing research activity and interest in this area since 1995 by both consultants and trade associations. Reasons to account for this mismatch are canvassed from within the academy and offered herein. Finally, important questions about the future direction of corporate real estate research are posed.

    Lessons from the Past and Future Directions for Corporate Real Estate Research

    Get PDF
    This study seeks to answer several questions about corporate real estate research. The first, Where should corporate real estate research be focused in the future? is addressed by a proposed alternative corporate real estate research framework that differs from what has been followed in the past. A second question that follows from the first is then addressed: Given such an alternative research framework, what types of corporate real estate issues merit research consideration? Finally, a third closely related question is then examined: Which research methodologies, databases and statistical tools are likely to prove useful to academic researchers seeking promotion and tenure, as well as corporate executives and others interested in better understanding the impacts of corporate real estate decisions?

    Structuring the Corporate Real Property Function for Greater "Bottom Line" Impact

    This study reviews the tasks a corporate real estate (CRE) function should undertake to create more opportunities for a company's real estate-related decisions to increase shareholder wealth. The major obstacles thwarting many corporate real estate executives from gaining the support they have been seeking from senior management, to more fully participate in higher value strategic planning efforts, are synthesized from several recent surveys (Arthur Andersen, 1993; Lambert, Poteete and Waltch, 1995.) Following a discussion of what corporate real estate staffs should be doing to contribute more to shareholder wealth, and what usually stands in their way, a proactive strategy is put forth for overcoming these obstacles. Lastly, in light of recent contributions to the literature (Duckworth, 1993; Joroff, Louargand, Lambert, and Becker, 1993; Kimbler and Rutherford, 1993; Lambert et al., 1995; Noha, 1993; Nourse and Roulac, 1993) on how to integrate strategic management of a company's real estate assets with strategic management of its business units and overall corporate strategy, some suggestions are made for (1) how to best organize the CRE function within a company, (2) how to make the best use of outside CRE service providers, and (3) what skills should prove most valuable to corporate real estate executives and their staffs.

    Identifying stochastic oscillations in single-cell live imaging time series using Gaussian processes

    Multiple biological processes are driven by oscillatory gene expression at different time scales. Pulsatile dynamics are thought to be widespread, and single-cell live imaging of gene expression has lead to a surge of dynamic, possibly oscillatory, data for different gene networks. However, the regulation of gene expression at the level of an individual cell involves reactions between finite numbers of molecules, and this can result in inherent randomness in expression dynamics, which blurs the boundaries between aperiodic fluctuations and noisy oscillators. Thus, there is an acute need for an objective statistical method for classifying whether an experimentally derived noisy time series is periodic. Here we present a new data analysis method that combines mechanistic stochastic modelling with the powerful methods of non-parametric regression with Gaussian processes. Our method can distinguish oscillatory gene expression from random fluctuations of non-oscillatory expression in single-cell time series, despite peak-to-peak variability in period and amplitude of single-cell oscillations. We show that our method outperforms the Lomb-Scargle periodogram in successfully classifying cells as oscillatory or non-oscillatory in data simulated from a simple genetic oscillator model and in experimental data. Analysis of bioluminescent live cell imaging shows a significantly greater number of oscillatory cells when luciferase is driven by a {\it Hes1} promoter (10/19), which has previously been reported to oscillate, than the constitutive MoMuLV 5' LTR (MMLV) promoter (0/25). The method can be applied to data from any gene network to both quantify the proportion of oscillating cells within a population and to measure the period and quality of oscillations. It is publicly available as a MATLAB package.Comment: 36 pages, 17 figure

    The effect of anthocyanin filters on plant behavior and development

    The red color of leaves found in nature during various seasons has long intrigued scientists and laymen alike. The voluminous literature is also evidence of the interest the phenomenon has aroused. Onslow\u27s \u27Anthocyanin Pigments of Plants\u27 and \u27The Biological Effects of Radiation,\u27 edited by Dugger are the two most exhaustive books on the chemical and physical aspects of anthocyanin. Lippmma came to the conclusion that anthocyanin plays a role of protection and that it is a genetically controlled characteristic of plants. It is thought by some that the pigments aid in temperature rise and thus cause increased transpiration. Chemically, the anthocyanin pigments occur in a number of forms. The most common two are found in beets and grapes
