Bayes and maximum likelihood for L^1-Wasserstein deconvolution of Laplace mixtures
No full textWe consider the problem of recovering a distribution function on the real line from observations additively contaminated with errors following the standard Laplace distribution. Assuming that the latent distribution is completely unknown leads to a nonparametric deconvolution problem. We begin by studying the rates of convergence relative to the -norm and the Hellinger metric for the direct problem of estimating the sampling density, which is a mixture of Laplace densities with a possibly unbounded set of locations: the rate of convergence for the Bayes' density estimator corresponding to a Dirichlet process prior over the space of all mixing distributions on the real line matches, up to a logarithmic factor, with the rate for the maximum likelihood estimator. Then, appealing to an inversion inequality translating the -norm and the Hellinger distance between general kernel mixtures, with a kernel density having polynomially decaying Fourier transform, into any -Wasserstein distance, , between the corresponding mixing distributions, provided their Laplace transforms are finite in some neighborhood of zero, we derive the rates of convergence in the -Wasserstein metric for the Bayes' and maximum likelihood estimators of the mixing distribution. Merging in the -Wasserstein distance between Bayes and maximum likelihood follows as a by-product, along with an assessment on the stochastic order of the discrepancy between the two estimation procedures
Adding Value by Health Care Real Estate: Parameters and Priorities
No full textPurpose Due to the transition of the Dutch health care sector from a governmentally steered domain towards regulated market forces, health care organisations have become fully responsible for their real estate. This paper explores if/how Dutch health care organisations adopt the concept of adding value by corporate and public real estate, which value parameters are included in daily practice and how, and which values are prioritized. Methodology Literature study and interviews with CEOs, project leaders, real estate managers and facility managers working in Dutch hospitals, assisted living facilities for the elderly, and mental health care facilities. The interviews were jointly prepared by students and the author of this paper being their main supervisor. Findings End-user satisfaction, stimulating innovation and increasing productivity are highly prioritized. The operationalisation into concrete design choices and strategic management of buildings-in-use is still underdeveloped. Which values are prioritized depends on the organisational objectives, the target group, the available budget, and the external context, in particular governmental policy and competition with other health care suppliers. Research implications Although much work has been done to operationalise the added value of corporate real estate and building related facilities, there is still a lack of a widely agreed taxonomy of added values and how to measure and manage these values. Ongoing international collaboration between researchers and practitioners is needed to build a common framework and to develop standardised measurement methods. Practical implications The insights can support decision makers in how to add value by public and corporate real estate, to explore conflicting values, and to improve current corporate and public real estate management by incorporating adding value parameters and taking into account the needs and interests of different stakeholders. Social implications A clear insight in value adding management of corporate real estate may result in a better fit between real estate and organisational objectives and individual needs. Originality/value The findings link added value theory to Corporate Real Estate Management in Dutch health care practice.Real Estate and HousingArchitecture and The Built Environmen
The Strategic Real Estate Framework: Processes, Linkages, Decisions
No full textThe intention of this work is to provide a contemporary perspective for understanding the real estate markets that can guide the involvement and decisions for all sectors of society's direct and indirect involvements with the real estate process, resources and market participants. Comprehension of the multifaceted, multidimensional, substantial segment of the economy known as real estate is best accomplished through a strategic framework. Because the real estate discipline lacks coherence and concurrence about what is the essence of real estate and what are the operative paradigms for comprehending and making order of the discipline, there is need for a strategic framework that is simultaneously synthesizing, integrating and comprehensive. The concept of the real estate strategy framework both provides the basis for gaining insights into the real estate discipline and also presents a means to connect a strategic approach to real estate with the act of real estate decision-making. By understanding the real estate process, those strategic influences on transactions that follow from the real estate process can be identified. This framework can enhance the quality, reliability and prudence of real estate decisions. By understanding these interdependencies and linkages, more effective decisionmaking concerning real estate interests and the objectives of participants in the real estate markets can be achieved.
Posterior rates of convergence for Dirichlet mixtures of exponential power densities
No full textA Dirichlet mixture of exponential power distributions, as a prior on densities supported on the real line in the problem of Bayesian density estimation, is a natural generalization of a Dirichlet mixture of normals, which has been shown to possess good frequentist asymptotic properties in terms of posterior consistency and rates of convergence. In this article, we establish upper bounds on the rates of convergence for the posterior distribution of a Dirichlet mixture of exponential power densities, assuming that the true density has the same form as the model. When the kernel is analytic and the mixing distribution has either compact support or sub-exponential tails, a nearly parametric rate, up to a logarithmic factor whose exponent depends on the tail behaviour of the base measure of the Dirichlet process and the exponential decay rate at zero of the prior for the scale parameter, is obtained. The result covers the important special case where the true density is a location mixture of normals and shows that a nearly parametric rate arises also when the prior on the scale contains zero in its support, provided it has a sufficiently fast decay rate at zero. This improves on some recent results on density estimation with Dirichlet mixtures of normals by allowing the inverse-gamma distribution, which is a commonly used prior on the square of the bandwidth. When the kernel is not infinitely differentiable at zero, as the case may be depending on the shape parameter, the posterior distribution is shown to concentrate around the sampling density at a slower rate
Towards an HLA Run-time Infrastructure with Hard Real-time Capabilities
No full textOur work takes place in the context of the HLA standard and its application in real-time systems context. The HLA standard is inadequate for taking into consideration the different constraints involved in real-time computer systems. Many works have been invested in order to providing real-time capabilities to Run Time Infrastructures (RTI) to run real time simulation. Most of these initiatives focus on major issues including QoS guarantee, Worst Case Transit Time (WCTT) knowledge and scheduling services provided by the underlying operating systems. Even if our ultimate objective is to achieve real-time capabilities for distributed HLA federations executions, this paper describes a preliminary work focusing on achieving hard real-time properties for HLA federations running on a single computer under Linux operating systems. Our paper proposes a novel global bottom up approach for designing real-time Run time Infrastructures and a formal model for validation of uni processor to (then) distributed real-time simulation with CERTI

Real estate implications of transitions in Dutch health care institutions
No full textDue to structural changes in laws and regulations and ways of financing, Dutch health care organisations are in a phase of reorientation and transition. As such, many strategical issues have to be solved that will influence their corporate real estate strategy. In such a dynamic context real estate represents a high risk. The transition requires increased transparency and understanding of performance. The current Dutch situation can be described as:•Increased vacancy arouses. Hypothesis: Health care organisations prevent vacancy by disposing of or reinvestments in existing locations, with improved quality of the remaining real estate.•Lower rates and increased uncertainty. Hypothesis: The response will consists of increased focus, demanding a proper preparation.•A growing dilemma of lower budget for real estate and high need for investments. Hypothesis: The level of available financial resources for the renewal of the stock and guaranteed sound management is questionable.The purpose of the research is to test these hypotheses in order to gain a better understanding of the qualitative and quantitative (financial) mutations in health care real estate and to bridge the gap between the current supply and the future demand.To which extent are Dutch health care organisations ready to realise the transition by the introduction of new concepts, in order to meet the future demand of health care real estate?Based on a survey, relevant real estate related data including performance parameters has been collected by AAG, a consultancy firm and shared service centre for health and care, in 2015 and 2016. This database is the starting point for benchmark analyses on the resilience and flexibility of health care organisations to provide the required transition.The data include qualitative data about the location, building, and user experience, and quantitative information (financial, physical, features). Mapping the current situation (IST) generates a better understanding of the (im)possibilities of the health care real estate in the Netherlands (1). In order to forecast the effects of the transition it is necessary to use future scenarios (SOLL) to reveal resilience and flexibility (2). Such scenarios are qualitative as well as quantitative – determining the possible maximum investment and improvement (3). These scenarios will be hold against the actual plans of the health care organisation (4).Design & Construction ManagementReal Estate Managemen
