From stars to patients: Lessons from space science and astrophysics for health care informatics

Big Data are revolutionizing nearly every aspect of the modern society. One area where this can have a profound positive societal impact is the field of Health Care Informatics (HCI), which faces many challenges. The key idea behind this study is: can we use some of the experience and technical and methodological solutions from the fields that have successfully adapted to the Big Data era, namely astronomy and space science, to help accelerate the progress of HCI? We illustrate this with examples from the Virtual Observatory framework, and the NCI EDRN project. An effective sharing and reuse of tools, methods, and experiences from different fields can save a lot of effort, time, and expense. HCI can thus benefit from the proven solutions to big data challenges from other domains

Characteristics of Pro-c Analogies and Blends between Research Publications

Dr Inventor is a tool that aims to enhance the professional (Pro-c) creativity of researchers by suggesting novel hypotheses, arising from analogies between publications. Dr Inventor processes original research documents using a combination of lexical analysis and cognitive computation to identify novel comparisons that suggest new research hypotheses, with the objective of supporting a novel research publication. Research on analogical reasoning strongly suggests that the value of analogy-based comparisons depends primarily on the strength of the mapping (or counterpart projection) between the two analogs. An evaluation study of a number of computer generated comparisons attracted creativity ratings from a group of practising researchers. This paper explores a variety of theoretically motivated metrics operating on different conceptual spaces, identifying some weak associations with user's creativity ratings. Surprisingly, our results show that metrics focused on the mapping appear to have less relevance to creativity than metrics assessing the inferences (blended space). This paper includes a brief description of a research project currently exploring the best research hypothesis generated during this evaluation. Finally, we explore PCA as a means of specifying a combined multiple metrics from several blending spaces as a basis for detecting comparisons to enhance researchers’ creativity

Extension of thermonuclear functions through the pathway model including Maxwell-Boltzmann and Tsallis distributions

The Maxwell-Boltzmannian approach to nuclear reaction rate theory is extended to cover Tsallis statistics (Tsallis, 1988) and more general cases of distribution functions. An analytical study of respective thermonuclear functions is being conducted with the help of statistical techniques. The pathway model, recently introduced by Mathai (2005), is utilized for thermonuclear functions and closed-form representations are obtained in terms of H-functions and G-functions. Maxwell-Boltzmannian thermonuclear functions become particular cases of the extended thermonuclear functions. A brief review on the development of the theory of analytic representations of nuclear reaction rates is given.Comment: 16 pages, LaTe

System occupancy of a two-class batch-service queue with class-dependent variable server capacity

Due to their wide area of applications, queueing models with batch service, where the server can process several customers simultaneously, have been studied frequently. An important characteristic of such batch-service systems is the size of a batch, that is the number of customers that are processed simultaneously. In this paper, we analyse a two-class batch-service queueing model with variable server capacity, where all customers are accommodated in a common first-come-first served single-server queue. The server can only process customers that belong to the same class, so that the size of a batch is determined by the number of consecutive same-class customers. After establishing the system equations that govern the system behaviour, we deduce an expression for the steady-state probability generating function of the system occupancy at random slot boundaries. Also, some numerical examples are given that provide further insight in the impact of the different parameters on the system performance

Somatization among ethnic minorities and immigrants: Why does it matter to Consultation Liaison Psychiatry?

The article describes the reasons why psychiatrists working in the field of consultation-liaison should be trained and aware of the relevance of culture in their everyday work. Moreover, the article aims at advertising the special-interest group on cultural CLP, a network of clinicians and researchers within the European Association of Psychosomatic Medicine that share their interest and activities in this subject

Solid weak BCC-algebras

We characterize weak BCC-algebras in which the identity $(xy)z=(xz)y$ is satisfied only in the case when elements $x,y$ belong to the same branch

Improving the Accuracy of Action Classification Using View-Dependent Context Information

Proceedings of: 6th International Conference, HAIS 2011, Wroclaw, Poland, May 23-25, 2011This paper presents a human action recognition system that decomposes the task in two subtasks. First, a view-independent classifier, shared between the multiple views to analyze, is applied to obtain an initial guess of the posterior distribution of the performed action. Then, this posterior distribution is combined with view based knowledge to improve the action classification. This allows to reuse the view-independent component when a new view has to be analyzed, needing to only specify the view dependent knowledge. An example of the application of the system into an smart home domain is discussed.This work was supported in part by Projects CICYT TIN2008-06742-C02-02/ TSI, CICYT TEC2008-06732-C02-02/TEC, CAM CONTEXTS (S2009/ TIC-1485) and DPS2008-07029-C02-02.Publicad

A Gradualist Approach to Criminality: Early British Socialists, Utopia and Crime

The attitudes of early British socialists to criminality are a thoroughly under-researched area of historical scholarship. This paper draws on the utopian ideas of Robert Owen, William Morris, H. G. Wells, Robert Blatchford, Edward Carpenter and Ramsay MacDonald as a vehicle for investigating the attitudes of mainstream fin de siècle British socialists to crime, punishment and penal reform. Placing these figures and their utopias along a spectrum that sees radical ‘Arcadian’ socialists on the far left, ‘technological’ socialists on the far right, and moderate socialists occupying the middle ground, it presents two principal findings. First it demonstrates how crime was predicted by most of the left to decrease to a minimum level under socialism. ‘Arcadians’, ‘technological’ and moderate socialists invoked different methods in this pursuit, but each were in essence grappling with the same broader issue of the relationship of the individual to the state under socialism. Secondly, examining the multifaceted ideological heritage of the British left in relation to their approaches to crime, it is argued that, despite the left’s gradualist philosophy, their own attitudes to criminality actually closely reflected utopian conceptions. Examination of these issues offers an important opportunity to re-evaluate the evolution of British socialist thought
