Overview on incorporating computer-aided diagnosis systems for dementia: Early detection of Alzheimer's disease
No full textDementia is one of the major issues in public health all over the world. Alzheimer's disease (AD) is its most common and famous form. Late detection of AD has irreparable effects for the people suffering from it. Cognitive assessment tests are the conventional approach to detect AD. They are quick to do, and not costly. However, they have low predictive values. Therefore, other ways such as magnetic resonance imaging (MRI) are used. Recently, advances in computer-aided diagnosis system (CADS) using MRI have provided useful information in the quantitative evaluation of AD at an early stage. Although it cannot be substituted with the doctors, but it helps. Many algorithms for CADS were presented, which means CADS is one of the growing techniques in this field. Because there is no standardized approach to determine the best one, it is essential to be familiar with general approaches to design a CADS. This chapter deals with a general approach for design and develop a reliable CADS using biomarkers extracted from MRI. The advancement of using CAS and MRI for AD are discusse
Process mining case study approach: Extraction of unconventional event logs to improve performance in Hospital Information Systems (HIS)
Get PDFBackground: Due to recent advancements in the computing technologies, process-mining algorithms can consequently apply complex numerical calculations in big data analysis with quick repetitions. It involved primarily in real-time systems such as banking, transport, and hospitals. However, process mining tending to play a vital role in the healthcare domain with promising results.
Objective: The goal is to extract the unconventional event log file from the process to improve system performance and to propose solutions to enhance system performance
Methods: The present research incorporated the performance filter technique to sort out misbehaved event logs from the process. We consider a sample of 100,000 patient cases over three-years from the local Hospital information systems (HIS).
Results: Results were emphasized with precise coordination, performance assessment by specific mining tool has done. Percentage of time taken to process unconventional event log files is validated as 63.67%, which means system performance getting low due to these events
Conclusion: In particular, to gain competitive advantage hospitals are trying to streamline their processes through an accurate view of the care flows. Several studies were done to integrate these techniques with hospital software systems, and we are come up with the contemporary idea of event log filtering
Keywords: Process mining, Process discovery, Event logs, HIS, and Process enhancement
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
