  22. The effect of time pressure on metacognitive control: developmental changes in self‑regulation and efficiency during learning.Gökhan Gönül, Nike Tsalas & Markus Paulus - forthcoming - Metacognition and Learning.
    The effect of time pressure on metacognitive control is of theoretical and empirical relevance and is likely to allow us to tap into developmental differences in performances which do not become apparent otherwise, as previous studies suggest. In the present study, we investigated the effect of time pressure on metacognitive control in three age groups (10-year-olds, 14-year-olds, and adults, n = 183). Using an established study time allocation paradigm, participants had to study two different sets of picture pairs, in an (...)

    Thinking Out Loud on Early Creation through the Lens of Hermeneutics of Sherlock Holmes (Towards a Model of Universe based on Turbulence-Generated Sound Theory).Victor Christianto & Florentin Smarandache - manuscript
    In recent years, apparently the Big Bang as described by the Lambda CDM-Standard Model Cosmology has become widely accepted by majority of physics and cosmology communities. Even some people have concluded that it has no serious alternative in horizon. Is that true? First, as we argued elsewhere, Big Bang story relies on singularity. In other words, when we are able to describe the observed data without invoking singularity, then Big Bang model is no longer required. Therefore, here we explore a (...)

  24. Generation of Biological Patterns and Form: Some Physical, Mathematical and Logical Aspects.Alfred Gierer - 1981 - Progress in Biophysics and Molecular Biology 37 (1):1-48.
    While many different mechanisms contribute to the generation of spatial order in biological development, the formation of morphogenetic fields which in turn direct cell responses giving rise to pattern and form are of major importance and essential for embryogenesis and regeneration. Most likely the fields represent concentration patterns of substances produced by molecular kinetics. Short range autocatalytic activation in conjunction with longer range “lateral” inhibition or depletion effects is capable of generating such patterns (Gierer and Meinhardt, 1972). Non-linear reactions (...)

  25. Gun Control: A European Perspective.Vincent C. Müller - 2015 - Essays in Philosophy 16 (2):247-261.
    From a European perspective the US debate about gun control is puzzling because we have no such debate: It seems obvious to us that dangerous weapons need tight control and that ‘guns’ fall under that category. I suggest that this difference occurs due to different habits that generate different attitudes and support this explanation with an analogy to the habits about knives. I conclude that it is plausible that individual knife-people or gun-people do not want tight regulatory legislation—but tight knife (...)

    Abstract—Generator set (genset) is a backup power supply which is used when the PLN supply is off. With such an important function, the generator set maintenance must be taken care of for long life durability. Monitoring activity is usually conducted on a regular basis, but still run manually by relying on operators who go directly to the plant. This research goes over the making of HMI remote control system for generator set in order to produce effective and continuous reporting. HMI (...)

  28. Robust Multiple Authority and Attribute Based Encryption for Access Control in Cloud Computing.P. S. Mona & M. Dhande ProfNutan - 2018 - International Journal on Recent and Innovation Trends in Computing and Communication 6 (3).
    Data access control is a challenging issue in public cloud storage systems. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) has been adopted as a promising technique to provide flexible, fine-grained and secure data access control for cloud storage with honest-but- curious cloud servers. However, in the existing CP-ABE schemes, the single attribute authority must execute the time-consuming user legitimacy verification and secret key distribution, and hence it results in a single-point performance bottleneck when a CP-ABE scheme is adopted in a large-scale cloud (...)

We have given far less attention to the issue of how to thoughtfully apply the evidence once we have it. That’s fine if all we care about is that our clinical decisions are evidence-based, but not so good if we also want them to be well-reasoned. Let us not forget that evidence based medicine (EBM) grew out of an interest in making medicine ‘rational’, (...)

  34. Coherent Causal Control: A New Distinction within Causation.Marcel Weber - 2022 - European Journal for Philosophy of Science 12 (4):69.
    The recent literature on causality has seen the introduction of several distinctions within causality, which are thought to be important for understanding the widespread scientific practice of focusing causal explanations on a subset of the factors that are causally relevant for a phenomenon. Concepts used to draw such distinctions include, among others, stability, specificity, proportionality, or actual-difference making. In this contribution, I propose a new distinction that picks out an explanatorily salient class of causes in biological systems. Some select causes (...)

  35. A Case for Virtue: Aristotle’s Psychology and Contemporary Accounts of Emotion Regulation.Paul Carron - 2014 - Images of Europe. Past, Present, Future: ISSEI 2014 - Conference Proceedings.
    This essay argues that recent evidence in neurobiology and psychology supports Aristotle’s foundational psychology and account of self-control and demonstrates that his account of virtue is still relevant for understanding human agency. There is deep correlation between the psychological foundation of virtue that Aristotle describes in The Nicomachean Ethics (NE)—namely his distinction between the rational and nonrational parts of the soul, the way that they interact, and their respective roles in self-controlled action—and dual-process models of moral judgment. Furthermore, Aristotle’s conception (...)

    Starting from the observation of the binary character YES/NOT of our decisions in relation to the information received from the environment, determining both our life and specie evolution by adaptation, it is defined the info-creational field and thought as an information operator on this field, allowing to describe the individual EGO as a receiver and producer information system, based on an operational and a programmed informational subsystem. Consciousness appears thus be an integrated information system which allows the adaptation to (...)

    Autism has been defined as a disorder of social cognition, interaction and communication where ritualistic, repetitive behaviors are commonly observed. But how should we understand the behavioral and cognitive differences that have been the main focus of so much autism research? Can high-level cognitive processes and behaviors be identified as the core issues people with autism face, or do these characteristics perhaps often rather reflect individual attempts to cope with underlying physiological issues?

Evolution drives natural selection while geometry may capture the logic of this selection and express it visually, in terms of specific generic properties representing some kind of advantage. Geometry is ideally suited for expressing the logic of evolutionary selection for symmetry, which is found in the shape curves of vein systems and other natural objects such as leaves, cell membranes, or tunnel systems built by ants.

  39. Philosophical controversies in the evaluation of medical treatments : With a focus on the evidential roles of randomization and mechanisms in Evidence-Based Medicine.Alexander Mebius - 2015 - Dissertation, Kth Royal Institute of Technology
    This thesis examines philosophical controversies surrounding the evaluation of medical treatments, with a focus on the evidential roles of randomised trials and mechanisms in Evidence-Based Medicine. Current 'best practice' usually involves excluding non-randomised trial evidence from systematic reviews in cases where randomised trials are available for inclusion in the reviews. The first paper challenges this practice and evaluates whether adding of evidence from non-randomised trials might improve the quality and precision of some systematic reviews. The second paper compares the (...)

    The field of mindfulness and the emerging science of heroism have a common interest in the causes and conditions of selfless altruism though up to this point there has been little cross-pollination. However, there is increasing evidence that mindfulness training delivers heroically relevant qualities such as increased attentional functioning, enhanced primary sensory awareness, greater conflict monitoring, increased cognitive control, reduced fear response, and an increase in loving kindness and self-sacrificing behaviors. Predicated on the notion of a “no self,” traditional mindfulness (...)

    Benchmarking automated theorem proving (ATP) systems using standardized problem sets is a well-established method for measuring their performance. However, the availability of such libraries for non-classical logics is very limited. In this work we propose a library for benchmarking Girard's (propositional) intuitionistic linear logic. For a quick bootstrapping of the collection of problems, and for discussing the selection of relevant problems and understanding their meaning as linear logic theorems, we use translations of the collection of Kleene's intuitionistic theorems (...)

  43. Meaning generation for constraint satisfaction. An evolutionary thread for biosemiotics (Biosemiotics Gatherings 2016).Christophe Menant - manuscript
    One of the mains challenges of biosemiotics is ‘to attempt to naturalize biological meaning’ [Sharov & all 2015]. That challenge brings to look at a possible evolutionary thread for biosemiotics based on meaning generation for internal constraint satisfaction, starting with a pre-biotic entity emerging from a material universe. Such perspective complements and extends previous works that used a model of meaning generation for internal constraint satisfaction (the Meaning Generator System) [Menant 2003a, b; 2011]. We propose to look at such (...)

    Abstract— In parallel to developing technology, demand for more energy makes us seek new energy sources. Wind and solar energy are the most popular ones owing to their abundance, ease of availability and convertibility to electric energy. This work covers realization of a hybrid renewable energy system. The scheme involves conversion of solar power and wind power into usable electrical energy using solar panel and by designing a wind turbine with appropriate calculations and specifications. Battery in this system is charged (...)

  46. Facilitating pre-service teachers to develop Regulation of Cognition with Learning Management System.Mary Gutman & Maria Gutman - 2017 - Educational Media International 54 (3):199-214.
    The object of the present study is to propose a technologically-based method for developing Regulation of Cognition (RC) among pre-service teachers in a pedagogical problem context. The research intervention was carried out by two groups during a Teaching Training Workshop, based on the IMPROVE instructional method, which was implemented in the Learning Management System (LMS). The first group (N=53) investigated the pedagogical problems with "dual perspectives (teacher and learner), and the other group (N=47) analyzed the same problems from (...)

British Journal of Health Psychology, 22, 186-206.William Van Gordon, Edo Shonin, Thomas Dunn, Javier Garcia-Campayo & Mark Griffiths - 2017 - British Journal of Health Psychology 22:186-206.
    Objectives. The purpose of this study was to conduct the first randomized controlled trial (RCT) to evaluate the effectiveness of a second-generation mindfulness-based intervention (SG-MBI) for treating fibromyalgia syndrome (FMS). Compared to first generation mindfulness-based interventions, SG-MBIs are more acknowledging of the spiritual aspect of mindfulness. Design. A RCT employing intent-to-treat analysis. Methods. Adults with FMS received an 8-week SG-MBI known as meditation awareness training (MAT; n = 74) or an active control intervention known as cognitive behaviour theory (...)

  49. Regulation of Trace Elements by Vitamin A in Paracetamol-induced Liver Toxicity in Rats.Amna Abdallah Ali, Khalda Awad Albdwai, Wafaa Ali Siddeg & Omer Mohamed Abdalla - 2019 - IJAMR 3 (3):1-9.
    Abstract: This study was aiming to determine the effect of the Vitamin A on paracetamol-induced hepatotoxicity. Fifteen rats were randomly divided into five groups; (three rats each) control group, paracetamol (1000 mg/kg body weight) was used to induce hepatotoxicity in albino rats. Vitamin A (Retinyl palmtate) administered at the dose levels of 100, 500 and1000 IU/kg body weights orally for 7 days prior to paracetamol dose. Hepatic toxicity was observed in paracetamol group; aspartate aminotransaminase (AST) level was high as compared (...)

  50. Logics Based on Linear Orders of Contaminating Values.Roberto Ciuni, Thomas Macaulay Ferguson & Damian Szmuc - 2019 - Journal of Logic and Computation 29 (5):631–663.
    A wide family of many-valued logics—for instance, those based on the weak Kleene algebra—includes a non-classical truth-value that is ‘contaminating’ in the sense that whenever the value is assigned to a formula φ⁠, any complex formula in which φ appears is assigned that value as well. In such systems, the contaminating value enjoys a wide range of interpretations, suggesting scenarios in which more than one of these interpretations are called for. This calls for an evaluation of systems with multiple (...)
