Auction Design with Loss Averse Bidders: The Optimality of All Pay Mechanisms
Auctioneers who have an indivisible object for sale and believe that bidders are risk neutral can find the recipe for an optimal auction in Myerson (1981); auctioneers who believe that bidders are loss averse can find it here: An optimal auction is an all pay auction with minimum bid, and any optimal mechanism is all pay
Quality of Life in Orthodontics
Orthodontic treatment goes beyond mere cosmetic enhancement; it significantly impacts various aspects of an individual\u27s quality of life. Beyond the physical benefits of improved oral function and prevention of dental issues, orthodontics also yields profound psychological benefits. Aligned teeth enhance self-confidence, reduce social anxiety, and contribute to better relationships and professional opportunities. Moreover, addressing dental concerns through orthodontic treatment reduces psychological distress and promotes overall happiness and satisfaction. Real-life case studies vividly illustrate the transformative effects of orthodontic interventions, emphasizing the importance of considering quality of life outcomes in dental care
Hypocoercivity for infinite-dimensional non-linear degenerate stochastic differential equations with multiplicative noise
We analyze infinite-dimensional non-linear degenerate stochastic differential
equations with multiplicative noise. First, essential m-dissipativity of their
associated Kolmogorov backward generators on defined on
smooth finitely based functions is established. Here is an appropriate
potential and is the invariant measure with density
w.r.t. an infinite-dimensional non-degenerate Gaussian measure. Second, we use
resolvent methods to construct corresponding right processes with infinite
lifetime, solving the martingale problem for the Kolmogorov backward
generators. They provide weak solutions, with weakly continuous paths, to the
non-linear degenerate stochastic partial differential equations. Moreover, we
identify the transition semigroup of such a process with the strongly
continuous contraction semigroup generated by the
corresponding Kolmogorov backwards generator. Afterwards, we apply a refinement
of the abstract Hilbert space hypocoercivity method, developed by Dolbeaut,
Mouhot and Schmeiser, to derive hypocoercivity of . I.e. we
take domain issues into account and use the formulation in the Kolmogorov
backwards setting worked out by Grothaus and Stilgenbauer. The method enables
us to explicitly compute the constants determining the exponential convergence
rate to equilibrium of . The identification between
and the transition semigroup of the process yields
exponential ergodicity of the latter. Finally, we apply our results to second
order in time stochastic reaction-diffusion and Cahn-Hilliard type equations
with multiplicative noise. More generally, we analyze corresponding couplings
of infinite-dimensional deterministic with stochastic differential equations
The Team-Mate Identification (TM-ID) Test: A Portable Apparatus for Collecting Decision Latencies for Players in Team Invasion Sports
Abstract. In team sports, effective execution of a pass depends on correctly and quickly identifying the intended receiver as a team-mate. The ability to make such identifications has been tested by showing players short video-clips of moving players. However, an apparatus is needed to enable researchers to collect latency data for these decisions at a standard that provides suitable accuracy for scientific research. For the TeamMate Identification (TM-ID) test, both identification times and response selections made by team players after viewing brief video-clips of moving athletes must be collected on response keys, for subsequent signal detection analysis. To do this, a timer is initiated when a light sensor fixed to the corner of a monitor screen detected a white square that had been edited into the video-clips. The observing player presses down on a home key, with six selection keys arranged in a semi-circular pattern. Decision time to release the home key and the selection key pressed ware then recorded. Using this apparatus participants view a series of randomly sequenced video-clips of the relevant locomotor skill, e.g., swimming or running performed by team-mates and unknowns. The apparatus designed and built for the TM-ID test is a compact and portable device, designed in this instance to work with a PC laptop system that provides a portable testing apparatus that could be taken to the athlete
Developing Crosslingual Ontologies in WissKI: Transcontinental Research Collaboration in the Africa Multiple Cluster of Excellence
Since July 2019, the Africa Multiple Cluster of Excellence at the University of Bayreuth has been funding a project dedicated to the creation of an Islamic Cultural Archive (ICA), a database designed for collaborative research in English, French and Arabic connecting researchers based in Germany and four African countries. The ICA project pursues individual but interconnected studies revolving around Islamic learning in Africa. Supported by IT specialists, we develop a digital platform that meets the related requirements. The ICA seeks to develop new approaches to the handling of data through establishing an ontology-based digital research environment building on WissKI, a set of modules that extends the content management system Drupal with semantic web technology. The chapter sheds light on the technical implications of our endeavor to connect diverse alphabets and data from various digital and digitized media. The research team members connect their diverse data sets to create synergies between various research foci and interests, ranging from the nexus of Islamic knowledge production, dissemination, and acquisition to the socio-religious, political-economic, and cultural dimensions of Islamic learning. The chapter shows how our system allows us to collect and archive different types of data, generate metadata through an ontology, and connect data beyond language barriers. Most notably, our data description method links the data through multilayered and multilingual tags, as well as through comprehensive cross-references, thus constituting an innovative way of data handling that can benefit researchers in Islamic Studies as well as cultural and literary studies more broadly

Clinical Oncology Society of Australia: Position statement on cancer-related malnutrition and sarcopenia
© 2020 The Authors. Nutrition & Dietetics published by John Wiley & Sons Australia, Ltd on behalf of Dietitians Australia. This position statement describes the recommendations of the Clinical Oncology Society of Australia (COSA) regarding management of cancer-related malnutrition and sarcopenia. A multidisciplinary working group completed a review of the literature, focused on evidence-based guidelines, systematic reviews and meta-analyses, to develop recommendations for the position statement. National consultation of the position statement content was undertaken through COSA members. All people with cancer should be screened for malnutrition and sarcopenia in all health settings at diagnosis and as the clinical situation changes throughout treatment and recovery. People identified as “at risk” of malnutrition or with a high-risk cancer diagnosis or treatment plan should have a comprehensive nutrition assessment; people identified as “at risk” of sarcopenia should have a comprehensive evaluation of muscle status using a combination of assessments for muscle mass, muscle strength and function. All people with cancer-related malnutrition and sarcopenia should have access to the core components of treatment, including medical nutrition therapy, targeted exercise prescription and physical and psychological symptom management. Treatment for cancer-related malnutrition and sarcopenia should be individualised, in collaboration with the multidisciplinary team (MDT), and tailored to meet needs at each stage of cancer treatment. Health services should ensure a broad range of health care professionals across the MDT have the skills and confidence to recognise malnutrition and sarcopenia to facilitate timely referrals and treatment. The position statement is expected to provide guidance at a national level to improve the multidisciplinary management of cancer-related malnutrition and sarcopenia
