    Determining the Number of Attributes in Cognitive Diagnosis Modeling.Pablo Nájera, Francisco José Abad & Miguel A. Sorrel - 2021 - Frontiers in Psychology 12.
    Cognitive diagnosis models allow classifying respondents into a set of discrete attribute profiles. The internal structure of the test is determined in a Q-matrix, whose correct specification is necessary to achieve an accurate attribute profile classification. Several empirical Q-matrix estimation and validation methods have been proposed with the aim of providing well-specified Q-matrices. However, these methods require the number of attributes to be set in advance. No systematic studies about CDMs dimensionality assessment have been conducted, which contrasts with the (...)

    How important is social support in determining patients’ suitability for transplantation? Results from a National Survey of Transplant Clinicians.Keren Ladin, Joanna Emerson, Zeeshan Butt, Elisa J. Gordon, Douglas W. Hanto, Jennifer Perloff, Norman Daniels & Tara A. Lavelle - 2018 - Journal of Medical Ethics 44 (10):666-674.
    BackgroundNational guidelines require programmes use subjective assessments of social support when determining transplant suitability, despite limited evidence linking it to outcomes. We examined how transplant providers weigh the importance of social support for kidney transplantation compared with other factors, and variation by clinical role and personal beliefs.MethodsThe National survey of the American Society of Transplant Surgeons and the Society of Transplant Social Work in 2016. Using a discrete choice approach, respondents compared two hypothetical patient profiles and selected one (...)

  3. Simulated Annealing with a Temperature Dependent Penalty Function.Julio Michael Stern - 1992 - ORSA Journal on Computing 4:311-319.
    We formulate the problem of permuting a matrix to block angular form as the combinatorial minimization of an objective function. We motivate the use of simulated annealing (SA) as an optimization tool. We then introduce a heuristic temperature dependent penalty function in the simulated annealing cost function, to be used instead of the real objective function being minimized. Finally we show that this temperature dependent penalty function version of simulated annealing consistently outperforms the standard (...)

    Multi-formalism modelling and simulation: Application to cardiac modelling.A. Defontaine, A. Hernández & G. Carrault - 2004 - Acta Biotheoretica 52 (4):273-290.
    Cardiovascular modelling has been a major research subject for the last decade. Different cardiac models have been developed at a cellular level as well as at the whole organ level. Most of these models are defined by a comprehensive cellular modelling using continuous formalisms or by a tissue-level modelling often based on discrete formalisms. Nevertheless, both views still suffer from difficulties that reduce their clinical applications: the first approach requires heavy computational resources while the second one is not (...)

    Design, Development, and Evaluation of a Second Generation Interactive Simulator for Engineering Ethics Education (SEEE2).Michael Alfred & Christopher A. Chung - 2012 - Science and Engineering Ethics 18 (4):689-697.
    This paper describes a second generation Simulator for Engineering Ethics Education. Details describing the first generation activities of this overall effort are published in Chung and Alfred (Sci Eng Ethics 15:189–199, 2009). The second generation research effort represents a major development in the interactive simulator educational approach. As with the first generation effort, the simulator places students in first person perspective scenarios involving different types of ethical situations. Students must still gather data, assess the situation, and make decisions. The (...)

    Estimation for Akshaya Failure Model with Competing Risks under Progressive Censoring Scheme with Analyzing of Thymic Lymphoma of Mice Application.Tahani A. Abushal, Jitendra Kumar, Abdisalam Hassan Muse & Ahlam H. Tolba - 2022 - Complexity 2022:1-27.
    In several experiments of survival analysis, the cause of death or failure of any subject may be characterized by more than one cause. Since the cause of failure may be dependent or independent, in this work, we discuss the competing risk lifetime model under progressive type-II censored where the removal follows a binomial distribution. We consider the Akshaya lifetime failure model under independent causes and the number of subjects removed at every failure time when the removal follows the binomial distribution (...)

    Incidence of dispersion of refractoriness and cellular coupling resistance on cardiac reentries and ventricular fibrillation.A. L. Bardou, R. G. Seigneuric, J.-L. Chassé & P. M. Auger - 1999 - Acta Biotheoretica 47 (3-4):199-207.
    We used computer simulations to study the possible role of the dispersion of cellular coupling, refractoriness or both, in the mechanisms underlying cardiac arrhythmias. Local ischemia was first assumed to induce cell to cell dispersion of the coupling resistance (Case 1), refractory period (Case 2), or both of them (Case 3). Our numerical experiments based on the van Capelle and Durrer model showed that vortices could not be induced by cell to cell variations. With cellular properties dispersed in a patchy (...)

    Design, development, and evaluation of an interactive simulator for engineering ethics education (seee).Christopher A. Chung & Michael Alfred - 2009 - Science and Engineering Ethics 15 (2):189-199.
    Societal pressures, accreditation organizations, and licensing agencies are emphasizing the importance of ethics in the engineering curriculum. Traditionally, this subject has been taught using dogma, heuristics, and case study approaches. Most recently a number of organizations have sought to increase the utility of these approaches by utilizing the Internet. Resources from these organizations include on-line courses and tests, videos, and DVDs. While these individual approaches provide a foundation on which to base engineering ethics, they may be limited in developing (...)

    The public health implications of maternal care trade-offs.A. Magdalena Hurtado, Carol A. Lambourne, Kim R. Hill & Karen Kessler - 2006 - Human Nature 17 (2):129-154.
    The socioeconomic and ethnic characteristics of parents are some of the most important correlates of adverse health outcomes in childhood. However, the relationships between ethnic, economic, and behavioral factors and the health outcomes responsible for this pervasive finding have not been specified in child health epidemiology. The general objective of this paper is to propose a theoretical approach to the study of maternal behaviors and child health in diverse ethnic and socioeconomic environments. The specific aims are: (a) to describe (...)

    An Empirical Inquiry on Knowledge Sharing Among Academicians in Higher Learning Institutions.T. Ramayah, Jasmine A. L. Yeap & Joshua Ignatius - 2013 - Minerva 51 (2):131-154.
    Universities are expected to be places where knowledge is shared freely among academicians. However, the reality shows that knowledge sharing is barely present within universities these days. As Malaysia shifts towards building a knowledge-based society, academic institutions, particularly the public universities, now face ever-growing faculty demands for sharing quality resources and expertise. As a result, knowledge sharing in academia has become a rising concern. The purpose of this study, then, is to uncover the factors that propel knowledge sharing among (...)

    An Examination of Mind Perception and Moral Reasoning in Ethical Decision-Making: A Mixed-Methods Approach.Isaac H. Smith, Andrew T. Soderberg, Ekaterina Netchaeva & Gerardo A. Okhuysen - 2022 - Journal of Business Ethics 183 (3):671-690.
    Taking an abductive, mixed-methods approach, we explore the content of people’s moral deliberations. In Study 1, we gather qualitative data from small groups of graduate business students discussing moral dilemmas. We analyze their conversations with a focus on how participants perceive others’ thoughts, opinions, and evaluations about the dilemmas and incorporate them into their reasoning. Ascribing such capacities to think and feel to others—i.e., mind perception—is central to morality. We use the conversations in Study 1 to identify whose minds (...)

    Hessenberg factorization and firework algorithms for optimized data hiding in digital images.Salama A. Mostafa, Jamal N. Hasoon, Muhanad Tahrir Younis & Methaq Talib Gaata - 2022 - Journal of Intelligent Systems 31 (1):440-453.
    Data hiding and watermarking are considered one of the most important topics in cyber security. This article proposes an optimized method for embedding a watermark image in a cover medium (color image). First, the color of the image is separated into three components (RGB). Consequently, the discrete wavelet transform is applied to each component to obtain four bands (high–high, high–low, low–high, and low–low), resulting in 12 bands in total. By omitting the low–low band from each component, a new square matrix (...)

    Towards using Unmanned Aerial Vehicles (UAVs) in Wilderness Search and Rescue.Michael A. Goodrich, Bryan S. Morse, Cameron Engh, Joseph L. Cooper & Julie A. Adams - 2009 - Interaction Studies. Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies / Social Behaviour and Communication in Biological and Artificial Systemsinteraction Studies 10 (3):453-478.
    Wilderness Search and Rescue is the process of finding and assisting persons who are lost in remote wilderness areas. Because such areas are often rugged or relatively inaccessible, searching for missing persons can take huge amounts of time and resources. Camera-equipped mini-Unmanned Aerial Vehicles have the potential for speeding up the search process by enabling searchers to view aerial video of an area of interest while closely coordinating with nearby ground searchers. In this paper, we report on lessons learned by (...)

    Linking the Governance of Research Consortia to Global Health Justice: A Case Study of Future Health Systems.Bridget Pratt & Adnan A. Hyder - 2017 - Journal of Law, Medicine and Ethics 45 (4):664-681.
    Global health research partnerships are increasingly taking the form of consortia. Recent scholarship has proposed what features of governance may be necessary for these consortia to advance justice in global health. That guidance purports three elements of global health research consortia are essential — their research priorities, research capacity development strategies, research translation strategies — and should be structured to promote the health of the worst-off globally. This paper adopted a reflective equilibrium approach, testing the proposed ethical guidance against (...)

    Islamic Governance, National Governance, and Bank Risk Management and Disclosure in MENA Countries.Hussein A. Abdou, Collins G. Ntim & Ahmed A. Elamer - 2020 - Business and Society 59 (5):914-955.
    We examine the relationships among religious governance, especially Islamic governance quality (IGQ), national governance quality (NGQ), and risk management and disclosure practices (RDPs), and consequently ascertain whether NGQ has a moderating influence on the IGQ–RDPs nexus. Using one of the largest data sets relating to Islamic banks from 10 Middle East and North Africa (MENA) countries from 2006 to 2013, our findings are threefold. First, we find that RDPs are higher in banks with higher IGQ. Second, we (...)

  18. Tradable Permit Markets for the Control of Point and Nonpoint Sources of Water Pollution: Technology-Based V. Collective Performance-Based Approaches.Michael A. Taylor - 2003 - Dissertation, The Ohio State University
    The United States Environmental Protection Agency has begun to encourage innovative market-based approaches to address nonpoint source water pollution. These water quality trading programs have the potential to achieve environmental standards at a lower overall cost. Two fundamental questions must be answered before these benefits can be realized: How will trades between point and nonpoint sources be monitored and enforced? and, How will nonpoint sources be included within a trading market? ;Point-nonpoint source trading can be accommodated through either a (...)

    Knill, Kersten, & Mamassian (Chapter 6) provide an interesting discussion of how the Bayesian formulation can be used to help investigate human vision. In their view, computational theories can be based on an ideal observer that uses Bayesian inference to make optimal use of available information. Four factors are important here: the image information used, the output structures estimated, the priors assumed (i.e., knowledge about the structure of the world), and the likelihood function used (i.e., knowledge about the projection of (...)

    Examining Quadratic Relationships Between Traits and Methods in Two Multitrait-Multimethod Models.Fred A. Hintz, Christian Geiser, G. Leonard Burns & Mateu Servera - 2019 - Frontiers in Psychology 10:389755.
    Multitrait-multimethod (MTMM) analysis is one of the most frequently employed methods to examine the validity of psychological measures. Confirmatory factor analysis (CFA) is a commonly used analytic tool for examining MTMM data through the specification of trait and method latent variables. Most contemporary CFA-MTMM models either do not allow estimating correlations between the trait and method factors or they are restricted to linear trait-method relationships. There is no theoretical reason why trait and method relationships should always be linear, and (...)

    Maximizing the Benefits of Participatory Design for Human–Robot Interaction Research With Older Adults.Wendy A. Rogers, Travis Kadylak & Megan A. Bayles - 2021 - Human Factors 64 (3):441–450.
    Objective We reviewed human–robot interaction (HRI) participatory design (PD) research with older adults. The goal was to identify methods used, determine their value for design of robots with older adults, and provide guidance for best practices. Background Assistive robots may promote aging-in-place and quality of life for older adults. However, the robots must be designed to meet older adults’ specific needs and preferences. PD and other user-centered methods may be used to engage older adults in the robot development process (...)

    Self-Interest, Deprivation, and Agency.Douglas A. Hicks - 2005 - Journal of the Society of Christian Ethics 25 (1):147-167.
    IN THIS ESSAY I ENGAGE THE DEBATE AMONG THEOLOGIANS, PHILOSOphers, and economists on the proper role of self-interest in the pursuit of economic well-being. Often, neither economists' use of self-interest nor critics' rejection of it is carefully specified. I consider conditions under which acting in one's self-interest is theologically and morally proper. Specifically, I argue that for socioeconomically disadvantaged persons, increased exercise of self-interest should not be regarded as sinful but as a fitting expansion of agency and well-being. Contextual factors (...)

    The quality of the products coming from different lines of production requires some tests called comparative life tests. For lines having the same facility, the lifetime of the product is distributed by Burr XII, the lifetime distribution, and units are tested under type-I generalized hybrid censoring scheme. The observed censoring data are used under maximum likelihood and the Bayes method to estimate the model parameters. The theoretical results are discussed and assessed through data analysis and Monte Carlo simulation study. (...)

    About one third of patients with epilepsy have seizures refractory to the medical treatment. Electrical stimulation mapping is the gold standard for the identification of “eloquent” areas prior to resection of epileptogenic tissue. However, it is time-consuming and may cause undesired side effects. Broadband gamma activity recorded with extraoperative electrocorticography during cognitive tasks may be an alternative to ESM but until now has not proven of definitive clinical value. Considering their role in cognition, the alpha and beta bands could further (...)

    When Treatment Pressures Become Coercive: A Context-Sensitive Model of Informal Coercion in Mental Healthcare.Christin Hempeler, Esther Braun, Sarah Potthoff, Jakov Gather & Matthé Scholten - forthcoming - American Journal of Bioethics:1-13.
    Treatment pressures are communicative strategies that mental health professionals use to influence the decision-making of mental health service users and improve their adherence to recommended treatment. Szmukler and Appelbaum describe a spectrum of treatment pressures, which encompasses persuasion, interpersonal leverage, offers and threats, arguing that only a particular type of threat amounts to informal coercion. We contend that this account of informal coercion is insufficiently sensitive to context and fails to recognize the fundamental power imbalance in mental healthcare. Based on (...)

    A Lasso approach to covariate selection and average treatment effect estimation for clustered RCTs using design-based methods.Peter Z. Schochet - 2022 - Journal of Causal Inference 10 (1):494-514.
    Statistical power is often a concern for clustered randomized control trials (RCTs) due to variance inflation from design effects and the high cost of adding study clusters (such as hospitals, schools, or communities). While covariate pre-specification can improve power for estimating regression-adjusted average treatment effects (ATEs), further precision gains can be achieved through covariate selection once primary outcomes have been collected. This article uses design-based methods underlying clustered RCTs to develop Lasso methods for the post-hoc selection of covariates for ATE (...)

    The parameters governing our behavior are in constant flux. Accurately capturing these dynamics in cognitive models poses a challenge to modelers. Here, we demonstrate a mapping of ACT-R's declarative memory onto the linear ballistic accumulator (LBA), a mathematical model describing a competition between evidence accumulation processes. We show that this mapping provides a method for inferring individual ACT-R parameters without requiring the modeler to build and fit an entire ACT-R model. Existing parameter estimation methods for the LBA can be (...)

    Constructing a Reward-Related Quality of Life Statistic in Daily Life—a Proof of Concept Study Using Positive Affect.Simone J. W. Verhagen, Claudia J. P. Simons, Catherine van Zelst & Philippe A. E. G. Delespaul - 2017 - Frontiers in Psychology 8:294592.
    Background: Mental healthcare needs person-tailored interventions. Experience Sampling Method (ESM) can provide daily life monitoring of personal experiences. This study aims to operationalize and test a measure of momentary reward-related Quality of Life (rQoL). Intuitively, quality of life improves by spending more time on rewarding experiences. ESM clinical interventions can use this information to coach patients to find a realistic, optimal balance of positive experiences (maximize reward) in daily life. rQoL combines the frequency of engaging in a relevant (...)

    A Semi-supervised Learning-Based Diagnostic Classification Method Using Artificial Neural Networks.Kang Xue & Laine P. Bradshaw - 2021 - Frontiers in Psychology 11.
    The purpose of cognitive diagnostic modeling is to classify students' latent attribute profiles using their responses to the diagnostic assessment. In recent years, each diagnostic classification model makes different assumptions about the relationship between a student's response pattern and attribute profile. The previous research studies showed that the inappropriate DCMs and inaccurate Q-matrix impact diagnostic classification accuracy. Artificial Neural Networks have been proposed as a promising approach to convert a pattern of item responses into a diagnostic classification in (...)

    Gathering Is Not Only for Girls.Guillermo Zorrilla-Revilla, Jesús Rodríguez & Ana Mateos - 2021 - Human Nature 32 (3):582-602.
    In some small-scale societies, a sexual division of labor is common. For subadult hunter-gatherers, the onset of this division dates to middle childhood and the start of puberty; however, there is apparently no physiological explanation for this timing. The present study uses an experimental approach to evaluate possible energetic differences by sex in gathering-related activities. The energetic cost of gathering-related activities was measured in a sample of 42 subjects of both sexes aged between 8 and 14 years. Body mass (...)

    A Rasch modeling approach to analyzing students’ incorrect answers on multiple-choice questionsPrimjena Rasch modeliranja u analizi netočnih odgovora studenata na pitanja višestrukog izbora.Džana Salibašić Glamočić & Vanes Mešić - 2022 - Metodicki Ogledi 29 (1):217-240.
    An analysis of students’ difficulties for a curricular topic may help the educator to gain better insight into students’ reasoning about that topic which is a prerequisite for high-quality teaching. The purpose of this study was to demonstrate how distractor analysis may be used for identifying students’ difficulties in a certain topic. In order to be in position to perform invariant measurement and to easily relate students’ difficulties to their achievement levels, we decided to take a Rasch modeling (...). Our study included 14 wave optics items and 286 students from five universities in Slovenia, Croatia, and Bosnia and Herzegovina. Rasch modeling was used to estimate item and student measures, as well as to create option probability curves which allowed us to relate students’ achievement levels to the choice of individual distractors. It has been found that all 14 included items function in line with the Rasch model. In 10 out of 14 items there were distractors chosen by at least 25% of students. For several out of these 10 items, the option probability curves indicated that attractiveness of individual distractors depended on students’ ability levels. We could conclude that the Rasch-based distractor analysis may provide very useful information for differentiation of physics instruction. Analiza studentskih poteškoća vezanih za određenu nastavnu temu može pomoći predavaču u stjecanju boljeg uvida u studentsko razumijevanje određene teme, što je preduvjet za visokokvalitetnu nastavu. Svrha ovog istraživanja sastojala se u demonstriranju načina na koji analize ometača mogu biti iskorištene za identificiranje studentskih poteškoća u određenom području. Kako bismo mogli provoditi invarijantna mjerenja i lako povezati studentske poteškoće s razinama njihovih postignuća, odlučili smo se studiju provesti u okviru Rasch formalizma. Naše istraživanje obuhvatilo je 14 zadataka iz područja valne optike i 286 studenata s pet sveučilišta u Sloveniji, Hrvatskoj te Bosni i Hercegovini. Rasch modeliranje korišteno je za procjenu težine zadataka i sposobnosti studenata, kao i za kreiranje krivulja vjerojatnosti ponuđenih opcija što nam je omogućilo povezivanje razine razumijevanja studenata s izborom pojedinačnih ometača. Utvrđeno je da svih 14 zadataka funkcionira u skladu s Rasch modelom. Za 10 zadataka imali smo ometače koje je odabralo najmanje 25 % studenata. Kod nekoliko od ovih 10 zadataka krivulje vjerojatnosti ponuđenih opcija ukazuju na to da atraktivnost pojedinačnih ometača ovisi o razinama sposobnosti učenika. Možemo zaključiti da analiza ometača primjenom Rasch modeliranja može dati vrlo korisne informacije za diferencijaciju nastave fizike. (shrink)

    Exploring Quality Evaluation of Innovation and Entrepreneurship Education in Higher Institutions Using Deep Learning Approach and Fuzzy Fault Tree Analysis.Changlin Wang, Puyang Zheng, Fengrui Zhang, Yufeng Qian, Yiyao Zhang & Yulin Zou - 2022 - Frontiers in Psychology 12.
    The quality of Innovation and Entrepreneurship Education in higher institutions is closely related to the degree to which the undergraduates absorb relevant innovation and entrepreneurship knowledge and their entrepreneurial motivation. Thus, an effective Evaluation of Educational Quality is essential. In particular, fault tree analysis, a common EEQ approach, has some disadvantages, such as fault data reliance and insufficient uncertainties handleability. Thereupon, this article first puts forward a theoretical model based on the deep learning method to analyze the (...)

    A Deep Evolutionary Approach to Bioinspired Classifier Optimisation for Brain-Machine Interaction.Jordan J. Bird, Diego R. Faria, Luis J. Manso, Anikó Ekárt & Christopher D. Buckingham - 2019 - Complexity 2019:1-14.
    This study suggests a new approach to EEG data classification by exploring the idea of using evolutionary computation to both select useful discriminative EEG features and optimise the topology of Artificial Neural Networks. An evolutionary algorithm is applied to select the most informative features from an initial set of 2550 EEG statistical features. Optimisation of a Multilayer Perceptron is performed with an evolutionary approach before classification to estimate the best hyperparameters of the network. Deep learning and tuning (...)

    Recurrent variational autoencoder approach for remaining useful life estimation.Nahuel Costa & Luciano Sánchez - forthcoming - Logic Journal of the IGPL.
    A new method for evaluating aircraft engine monitoring data is proposed. Commonly, prognostics and health management systems use knowledge of the degradation processes of certain engine components together with professional expert opinion to predict the Remaining Useful Life (RUL). New data-driven approaches have emerged to provide accurate diagnostics without relying on such costly processes. However, most of them lack an explanatory component to understand model learning and/or the nature of the data. A solution based on a novel recurrent version of (...)

    A Multifocal and Integrative View of the Influencers of Ethical Attitudes Using Qualitative Configurational Analysis.Nicole A. Celestine, Catherine Leighton & Chris Perryer - 2020 - Journal of Business Ethics 162 (1):103-122.
    Ethical attitudes and behaviour are complex. This complexity extends to the influencers operating at different levels both outside and within the organisation, and in different combinations for different individuals. There is hence a growing need to understand the proximal and distal influencers of ethical attitudes, and how these operate in concert at the individual, organisational, and societal levels. Few studies have attempted to combine these main research streams and systematically examine their combined impact. The minority of studies that have taken (...)

  47. A Comparison of Penalized Maximum Likelihood Estimation and Markov Chain Monte Carlo Techniques for Estimating Confirmatory Factor Analysis Models With Small Sample Sizes.Oliver Lüdtke, Esther Ulitzsch & Alexander Robitzsch - 2021 - Frontiers in Psychology 12.
    With small to modest sample sizes and complex models, maximum likelihood estimation of confirmatory factor analysis models can show serious estimation problems such as non-convergence or parameter estimates outside the admissible parameter space. In this article, we distinguish different Bayesian estimators that can be used to stabilize the parameter estimates of a CFA: the mode of the joint posterior distribution that is obtained from penalized maximum likelihood estimation, and the mean, median, or mode of the marginal (...)

  48. Explaining Altruism: A Simulation-Based Approach and its Limits.Eckhart Arnold - 2008 - Ontos Verlag.
    Employing computer simulations for the study of the evolution of altruism has been popular since Axelrod's book "The Evolution of Cooperation". But have the myriads of simulation studies that followed in Axelrod's footsteps really increased our knowledge about the evolution of altruism or cooperation? This book examines in detail the working mechanisms of simulation based evolutionary explanations of altruism. It shows that the "theoretical insights" that can be derived from simulation studies are often quite arbitrary and of little use for (...)

    A generalized double robust Bayesian model averaging approach to causal effect estimation with application to the study of osteoporotic fractures.Claudia Beaudoin & Denis Talbot - 2022 - Journal of Causal Inference 10 (1):335-371.
    Analysts often use data-driven approaches to supplement their knowledge when selecting covariates for effect estimation. Multiple variable selection procedures for causal effect estimation have been devised in recent years, but additional developments are still required to adequately address the needs of analysts. We propose a generalized Bayesian causal effect estimation algorithm to perform variable selection and produce double robust estimates of causal effects for binary or continuous exposures and outcomes. GBCEE employs a prior distribution that targets the (...)

  50. Quality of life--a response to K C Calman.A. Cribb - 1985 - Journal of Medical Ethics 11 (3):142-145.
    There is no technical language with which to speak of patients' quality of life, there are no standard measures and no authority to validate criteria of measurement. It is well known that 'professionals' tend, often for institutional reasons, to play down or undervalue factors which are not defined by their particular expertise. It is fortunate that, despite this tendency, there is a growing interest in broadening the evaluation of medical care, but there is still a need to clarify what (...)
