    Professor Robert E Wright of the Department of Economics, University of Strathclyde organised a one-day workshop titled: "Demographic Change and Housing Markets", held in Glasgow on February 15, 2012. The workshop consisted of six presentations and was attended by over 40 participants from academia, government, charities and business. The workshop was funded by the Scottish Institute of Research in Economics (SIRE) and the Scottish Economic Society (SES). The workshop brought together individuals carrying out current and leading research into the major links between demographic change and housing markets

    Cost-sensitive Learning for Utility Optimization in Online Advertising Auctions

    One of the most challenging problems in computational advertising is the prediction of click-through and conversion rates for bidding in online advertising auctions. An unaddressed problem in previous approaches is the existence of highly non-uniform misprediction costs. While for model evaluation these costs have been taken into account through recently proposed business-aware offline metrics -- such as the Utility metric which measures the impact on advertiser profit -- this is not the case when training the models themselves. In this paper, to bridge the gap, we formally analyze the relationship between optimizing the Utility metric and the log loss, which is considered as one of the state-of-the-art approaches in conversion modeling. Our analysis motivates the idea of weighting the log loss with the business value of the predicted outcome. We present and analyze a new cost weighting scheme and show that significant gains in offline and online performance can be achieved.Comment: First version of the paper was presented at NIPS 2015 Workshop on E-Commerce: https://sites.google.com/site/nips15ecommerce/papers Third version of the paper will be presented at AdKDD 2017 Workshop: adkdd17.wixsite.com/adkddtargetad201

    Enron versus EUSES: A Comparison of Two Spreadsheet Corpora

    Full text link
    Spreadsheets are widely used within companies and often form the basis for business decisions. Numerous cases are known where incorrect information in spreadsheets has lead to incorrect decisions. Such cases underline the relevance of research on the professional use of spreadsheets. Recently a new dataset became available for research, containing over 15.000 business spreadsheets that were extracted from the Enron E-mail Archive. With this dataset, we 1) aim to obtain a thorough understanding of the characteristics of spreadsheets used within companies, and 2) compare the characteristics of the Enron spreadsheets with the EUSES corpus which is the existing state of the art set of spreadsheets that is frequently used in spreadsheet studies. Our analysis shows that 1) the majority of spreadsheets are not large in terms of worksheets and formulas, do not have a high degree of coupling, and their formulas are relatively simple; 2) the spreadsheets from the EUSES corpus are, with respect to the measured characteristics, quite similar to the Enron spreadsheets.Comment: In Proceedings of the 2nd Workshop on Software Engineering Methods in Spreadsheet

    The development of enterprises depends on the effective use of IT and e-business solutions. It is tied to the skillful investment, based on the long-haul and strategic decisions adapted from the BITA (Business IT Alignment) models. However, it appears that the workshop that supports professionally the BSC(IT) project work, in practice, is so complex and laborious, that it is destined principally for the large enterprises. This article, based on actual reports, depicts a certain distance between the companies. That distance, when left to itself, will eventually make the development of the small and medium-sized enterprises impossible

    Workflow support for simulation of service oriented B-to-C transaction

    Computation technologies and computer tools offer varied resources for the implementation of applications of electronic commerce (e-commerce). The current organizational models are based on nets of associations that are integrated to achieve business objectives. Therefore, the effectiveness of the commercial operation doesn't only depend on an appropriate configuration of technologies but also on efficiency in the business services. Service-Oriented Architecture (SOA) is an architectural style for distributed computation that considers the creation and administration of business services. With Web Services the services can be published in the Web and accessed by applications independently from language and technology. In this work a workflow support for the modeling and simulation of applications of e-commerce based on services and technologies Web Services is proposed. Tools are applied of processes modeling, with their integration in TIBCO that result in the modeling of a process business to consumer (b-to-c), their simulation and the evaluation of metrics of performanceI Workshop Innovación en Sistemas de Software (WISS)Red de Universidades con Carreras en Informática (RedUNCI

    This report summarises the presentations, discussions, and main results of the ECOOP’01 Workshop on Object-Oriented Business Solutions (WOOBS). It was not a pure scientific meeting, but a mixed gathering where people from the industry and the academia met to exchange ideas, experiences and build a network of relationships with others committed to the emergence of object-oriented business solutions. WOOBS had an invited talk on quality of service, twelve presentations and lively discussions during and after them. The main conclusions were on the importance of Multi-Organisational Web-Based Systems in today’s e-commerce world, which justifies the study of a new multidisciplinary paradigm called Web-Oriented Programming

    Pharmaceuticals and personal care products in the environment: What are the big questions?

    Get PDF
    Background: Over the past 10-15 years, a substantial amount of work has been done by the scientific, regulatory, and business communities to elucidate the effects and risks of pharmaceuticals and personal care products (PPCPs) in the environment. Objective: This review was undertaken to identify key outstanding issues regarding the effects of PPCPs on human and ecological health in order to ensure that future resources will be focused on the most important areas. Data sources: To better understand and manage the risks of PPCPs in the environment, we used the "key question" approach to identify the principle issues that need to be addressed. Initially, questions were solicited from academic, government, and business communities around the world. A list of 101 questions was then discussed at an international expert workshop, and a top-20 list was developed. Following the workshop, workshop attendees ranked the 20 questions by importance. Data synthesis: The top 20 priority questions fell into seven categories: a) prioritization of substances for assessment, b) pathways of exposure, c) bioavailability and uptake, d) effects characterization, e) risk and relative risk, f) antibiotic resistance, and g) risk management. Conclusions: A large body of information is now available on PPCPs in the environment. This exercise prioritized the most critical questions to aid in development of future research programs on the topic.Centro de Investigaciones del Medioambient
