Attention to 'sustainability' and energy efficiency rating schemes in the commercial property sector has increased rapidly during the past decade. In the UK, commercial properties have been certified ...under the BREEAM rating scheme since 1999, offering fertile ground to investigate the economic dynamics of 'green' certification in the commercial property market. This paper documents that, over the 2000–09 period, the expanding supply of green buildings within a given London neighbourhood had a positive impact on average rents and prices, but reduced rents and prices for environmentally certified real estate. The results suggest that there is a gentrification effect from green buildings. However, each additional "green" building decreases the marginal effect of certification in the rental and transaction markets by 2 per cent and 5 per cent respectively. In addition, controlling for lease contract features, like contract length and the rent-free period, modifies the impact of environmental certification on rental prices.
PulseNet International is a global network dedicated to laboratory-based surveillance for food-borne diseases. The network comprises the national and regional laboratory networks of Africa, Asia ...Pacific, Canada, Europe, Latin America and the Caribbean, the Middle East, and the United States. The PulseNet International vision is the standardised use of whole genome sequencing (WGS) to identify and subtype food-borne bacterial pathogens worldwide, replacing traditional methods to strengthen preparedness and response, reduce global social and economic disease burden, and save lives. To meet the needs of real-time surveillance, the PulseNet International network will standardise subtyping via WGS using whole genome multilocus sequence typing (wgMLST), which delivers sufficiently high resolution and epidemiological concordance, plus unambiguous nomenclature for the purposes of surveillance. Standardised protocols, validation studies, quality control programmes, database and nomenclature development, and training should support the implementation and decentralisation of WGS. Ideally, WGS data collected for surveillance purposes should be publicly available, in real time where possible, respecting data protection policies. WGS data are suitable for surveillance and outbreak purposes and for answering scientific questions pertaining to source attribution, antimicrobial resistance, transmission patterns, and virulence, which will further enable the protection and improvement of public health with respect to food-borne disease.
Agents are often better informed than the clients who hire them and may exploit this informational advantage. Real estate agents have an incentive to convince clients to sell their houses too cheaply ...and too quickly. We test these predictions by comparing home sales in which real estate agents are hired to when an agent sells his own home. Consistent with the theory, we find homes owned by real estate agents sell for 3.7% more than other houses and stay on the market 9.5 days longer, controlling for observables. Greater information asymmetry leads to larger distortions.
Provides a revolutionary conceptual framework and practical tools to quantify uncertainty and recognize the value of flexibility in real estate development This book takes a practical "engineering" ...approach to the valuation of options and flexibility in real estate. It presents simple simulation models built in universal spreadsheet software such as Microsoft Excel®. These realistically reflect the varying and erratic sources of uncertainty and price dynamics that uniquely characterize real estate. The text covers new analytic procedures that are valuable for existing properties and enable a new, more profitable perspective on the planning, design, operation, and evaluation of large-scale, multi-phase development projects. The book thereby aims to significantly improve valuation and investment decision making. Flexibility and Real Estate Valuation under Uncertainty: A Practical Guide for Developers is presented at 3 levels. First, it introduces and explains the concepts underlying the approach at a basic level accessible to non-technical and non-specialized readers. Its introductory and concluding chapters present the important "big picture" implications of the analysis for economics and valuation and for project design and investment decision making. At a second level, the book presents a framework, a roadmap for the prospective analyst. It describes the practical tools in detail, taking care to go through the elements of the approach step-by-step for clarity and easy reference. The third level includes more technical details and specific models. An Appendix discusses the technical details of real estate price dynamics. Associated web pages provide electronic spreadsheet templates for the models used as examples in the book. Some features of the book include: • Concepts and tools that are simple and accessible to a broad audience of practitioners; • An approach relevant for all development projects; • Complementarity with the author's Commercial Real Estate Analysis & Investments—the most-cited real estate investments textbook on the market. Flexibility and Real Estate Valuation under Uncertainty: A Practical Guide for Developers is for everyone studying or concerned with the implementation of large-scale or multi-phase real estate development projects, as well as property investment and valuation more generally.
The subject of real estate is increasingly becoming important, especially in the countries of the developing world. States and governments realise that real estate is a corner stone of socio-economic ...development. Real estate development contributes immensely to the gross physical capital formation. Its formation, construction and ancillary sectors contribute to the employment, infrastructure development and gross domestic product. The main challenges about real estate is about where to develop it, how to develop it, how to manage and compute valuations about it. Such are the issues discussed in this volume. The book draws on Zimbabwe as a case study, to demonstrate the critical aspects that define theory and real estate practice in various contexts - national, regional and international.
We present a simple, fully-convolutional model for real-time (<inline-formula><tex-math notation="LaTeX">>30</tex-math> ...<mml:math><mml:mrow><mml:mo>></mml:mo><mml:mn>30</mml:mn></mml:mrow></mml:math><inline-graphic xlink:href="zhou-ieq1-3014297.gif"/> </inline-formula> fps) instance segmentation that achieves competitive results on MS COCO evaluated on a single Titan Xp, which is significantly faster than any previous state-of-the-art approach. Moreover, we obtain this result after training on only one GPU . We accomplish this by breaking instance segmentation into two parallel subtasks: (1) generating a set of prototype masks and (2) predicting per-instance mask coefficients. Then we produce instance masks by linearly combining the prototypes with the mask coefficients. We find that because this process doesn't depend on repooling, this approach produces very high-quality masks and exhibits temporal stability for free. Furthermore, we analyze the emergent behavior of our prototypes and show they learn to localize instances on their own in a translation variant manner, despite being fully-convolutional. We also propose Fast NMS, a drop-in 12 ms faster replacement for standard NMS that only has a marginal performance penalty. Finally, by incorporating deformable convolutions into the backbone network, optimizing the prediction head with better anchor scales and aspect ratios, and adding a novel fast mask re-scoring branch, our YOLACT++ model can achieve 34.1 mAP on MS COCO at 33.5 fps, which is fairly close to the state-of-the-art approaches while still running at real-time.
A new revolution in homeownership and living has been sweeping the booming cities of China. This time the main actors on the social stage are not peasants, migrants, or working-class proletariats but ...middle-class professionals and entrepreneurs in search of a private paradise in a society now dominated by consumerism. No longer seeking happiness and fulfillment through collective sacrifice and socialist ideals, they hope to find material comfort and social distinction in newly constructed gated communities. This quest for the good life is profoundly transforming the physical and social landscapes of urban China.
Li Zhang, who is from Kunming, the capital of Yunnan province, turns a keen ethnographic eye on her hometown. She combines her analysis of larger political and social issues with fine-grained details about the profound spatial, cultural, and political effects of the shift in the way Chinese urban residents live their lives and think about themselves.In Search of Paradiseis a deeply informed account of how the rise of private homeownership is reconfiguring urban space, class subjects, gender selfhood, and ways of life in the reform era.
New, seemingly individualistic lifestyles mark a dramatic move away from yearning for a social utopia under Maoist socialism. Yet the privatization of property and urban living have engendered a simultaneous movement of public engagement among homeowners as they confront the encroaching power of the developers. This double movement of privatized living and public sphere activism, Zhang finds, is a distinctive feature of the cultural politics of the middle classes in contemporary China. Theoretically sophisticated and highly accessible, Zhang's account will appeal not only to those interested in China but also to anyone interested in spatial politics, middle-class culture, and postsocialist governing in a globalizing world.
