Much of our know-how is acquired through practice: we learn how to cook by cooking, how to write by writing, and how to dance by dancing. As Aristotle argues, however, this kind of learning is puzzling, since engaging in it seems to require possession of the very knowledge one seeks to obtain. After showing how a version of the puzzle arises from a set of attractive principles, I argue that the best solution is to hold that knowledge-how comes in degrees, (...) and through practice a person gradually learns how to do something. However, the two standard accounts of know-how in the literature, intellectualism and anti-intellectualism, cannot properly account for the distinctive way in which know-how is gradually acquired by practice, a process in which conceptual representations and practical abilities are intimately interwoven. Drawing on Gareth Evans's work, I outline an account that may do so, and use this account to distinguish between two forms of learning to explain why skill generally cannot be learnt through testimony, and requires practice.

We consider an objection of Hans Kamp (based on an example by Barbara Partee) to Robert Stalnaker's model of context.

We address the need for a model by considering two competing theories regarding the origin of life: (i) the Metabolism First theory, and (ii) the RNA World theory. We discuss two interrelated points, namely: (i) Models are valuable tools for understanding both the processes and intricacies of origin-of-life issues, and (ii) Insights from models also help us to evaluate the core objection to origin-of-life theories, called “the inefficiency objection”, which is commonly raised by proponents of both the Metabolism First theory (...) and the RNA World theory against each other. We use Simpson’s Paradox (SP) as a tool for challenging this objection. We will use models in various senses, ranging from taking them as representations of reality to treating them as theories/accounts that provide heuristics for probing reality. In this paper, we will frequently use models and theories interchangeably. Additionally, we investigate Conway’s Game of Life and contrast it with our SP-based approach to emergence-of-life issues. Finally, we discuss some of the consequences of our view. A scientific model is testable in three senses: (i) a logical sense, (ii) a nomological sense, and (iii) a current technological sense. The SP-based model is testable in the first two senses but it is not feasible to test it using current technology. (shrink)

Our contention is that while what may be termed woke capitalism is the result of real changes in both the material structure of capitalism and its ideological superstructure, those are not changes pulling in the same direction. The main material development is the consolidation of the shift from a quasi-deterministic to a more pronouncedly probabilistic nexus of class and race. But it is unclear that this makes much difference to the material prospects of the vast majority of people of color (...) or indeed of people in general. Indeed, the racial permeability of the upper classes is accompanied by an increased and inverse racial permeability of the underclass. Diversification is so elite-driven that it is unlikely to proceed beyond the cosmetic, and for that reason it seems that diversification does not necessarily correspond to any major structural changes in the relations between groups of people, whether we consider them as arranged by class, race, or the intersection of the two. It follows that the politics of representation should not be regarded as a vehicle for the agenda of the materialist left. We propose instead a responsive universalist approach—responsive to racism and all other forms of marginalization and different from the homogenizing universalism of class-only politics. (shrink)

Nicholas Shea offers Varitel Semantics as a naturalistic account of mental content. I argue that the account secures determinate content only by appeal to pragmatic considerations, and so it fails to respect naturalism. But that is fine, because representational content is not, strictly speaking, necessary for explanation in cognitive science. Even in Shea’s own account, content serves only a variety of heuristic functions.

Is understanding subject to a factivity constraint? That is, must the agent’s representation of some subject matter be accurate in order for her to understand that subject matter? ‘No’, I argue in this paper. As an alternative, I formulate a novel manipulationist account of understanding. Rather than correctly representing, understanding, on this account, is a matter of being able to manipulate a representation of the world to satisfy contextually salient interests. This account of understanding is preferable to factivism, I argue, (...) mainly for simplicity reasons. While it explains the intuitive data about understanding as successfully as factivist accounts, it is simpler by virtue of reducing the value truth bestows on understanding to that of usability.

A belief in a firm correspondence between objects, ideas, and their representation in language pervaded the works of Anne Robert Jacques Turgot

(1727–1781) in 1750. This conviction is particularly manifest in Turgot’s sharp critique of Berkeley’s philosophical system and his remarks on Maupertuis’s reconstruction of the origin of language. During the 1750s Turgot’s epistemological views underwent a change, apparent in two of his contributions to the Encyclopédie: the entries Existence and Étymologie (1756). These articles included a reassessment of Berkeleyan immaterialism, facing (...) an ultimate crisis of definition and representation. A similar development may be traced in contemporary works by Condillac and Diderot. Turgot’s Encyclopédie entries also envisaged a new science, an archeology of the human mind aided by the examination of linguistic development and change. This entailed the scientific verification of conjectures in any historical account of ideas, turning etymological

and psychological inquiries into what Turgot termed ‘experimental metaphysics’. (shrink)

It is truly critical and crucial to analyze the revolutionary and radical role of technology in defining the aesthetic experience of modern man. Printmaking has initiated mass communication of visuals, and photography has re-defined realism, creating an alternate possibility of ‘seeing’ other than physically being with the object itself. Virtual reality and other artificial platforms are further facilitating this change in unpredictable ways. Inevitably, the criteria for aesthetic appreciation has transcended its traditional norms, related to concepts like ‘originality’ and asks (...) critical questions addressing the newer problems of aesthetics, in the background of mechanical reproduction and the irrevocable alteration it has brought to the sensorial experience of the new age. This article attempts to trace the status of these questions by analyzing the historiography of photographs, and graphic prints and their relationship with the new aesthetic idiom as well. (shrink)

I compare two different arguments for the importance of bringing new voices into science: arguments for increasing the representation of women, and arguments for the inclusion of the public, or for “citizen science”. I suggest that in each case, diversifying science can improve the quality of scientific results in three distinct ways: epistemically, ethically, and politically. In the first two respects, the mechanisms are essentially the same. In the third respect, the mechanisms are importantly different. Though this might appear to (...) suggest a broad similarity between the cases, I show that the analysis reveals an important respect in which efforts to include the public are more complex. With citizen science programs, unlike with efforts to bring more women into science, the three types of improvement are often in conflict with one another: improvements along one dimension may come at a cost on another dimension, suggesting difficult trade-offs may need to be made.

Here we present what we believe is a novel account of what languages are, along with an axiomatically rich representation of languages and language-related data that is based on this account. We propose an account of languages as aggregates of dispositions distributed across aggregates of persons, and in doing so we address linguistic competences and the processes that realize them. This paves the way for representing additional types of language-related entities. Like demographic data of other sorts, data about languages may (...) be of use to researchers in a number of areas, including biomedical research. Data on the languages used in clinical encounters are typically included in medical records, and capture an important factor in patient-provider interactions. Like many types of patient and demographic data, data on a person’s preferred and primary languages are organized in different ways by different systems. This can be a barrier to data integration. We believe that a robust framework for representing language in general and preferred and primary language in particular – which has been lacking in ontologies thus far – can promote more successful integration of language-related data from disparate data sources.

We extend the framework of Inductive Logic to Second Order languages and introduce Wilmers' Principle, a rational principle for probability functions on Second Order languages. We derive a representation theorem for functions satisfying this principle and investigate its relationship to the first order principles of Regularity and Super Regularity.

This paper reconsiders Ockham's critique of the species theory of cognition. As Ockham understands this theory, it says that the direct objects of cognition are mental representations, or species. According to many commentators, one of Ockham's main objections to this theory was that, if the direct objects of cognition are species rather than external objects, we will never be able to establish whether or not a given species is a veridical representation of the world. In this paper I argue (...) that this line of interpretation sits uneasily with Ockham's epistemology, and offer a new interpretation of Ockham's critique of species. (shrink)

Nick Shea’s Representation in Cognitive Science commits him to representations in perceptual processing that are about probabilities. This commentary concerns how to adjudicate between this view and an alternative that locates the probabilities rather in the representational states’ associated “attitudes”. As background and motivation, evidence for probabilistic representations in perceptual processing is adduced, and it is shown how, on either conception, one can address a specific challenge Ned Block has raised to this evidence.

This chapter uncovers the complex negotiations for authority in various representations about futures of life which have been advanced by different branches of the sciences, and have culminated in the emerging concept of life as algorithm. It charts the historical shifts in expertise and representations of life, from naturalists, to mathematical modellers, and specialists in computation, and argues that physicists, game theorists, and economists now take a leading role in explaining and projecting futures of life. The chapter identifies (...) Richard Dawkins and Max Tegmark at the forefront of the concept of life as algorithm: the first inspired by game theory as a means to study evolution; the second proposing that a materialist basis of life could place humans and artificial intelligence on an equal footing. Through close reading of their respective texts, the chapter demonstrates that both thinkers consider life as an algorithm programmed to achieve success in survival and reproduction. (shrink)

This article proposes to read John Banville’s The Book of Evidence, a crime story narrated from the protagonist’s first-person gaze, from a Lacanian perspective by referring to his mirror stage theory. As an extension of testimonial literature, the novel is deemed to be a narrative of introspective self-examination, thus introducing a creation of “the self” paralleling the text. The protagonist’s mnemonic narrative is accompanied by the idea of an alternative world of not only self-expression but also self-depiction and presentation, as (...) in Lacan’s Imaginary. This self-creation, however, may not be as innocent as it seems. The reason for this is that although the mirror phase involves a transition from the Imaginary to the Symbolic, it presupposes the role of the other, biologically (m)other, in order to accustom the subject to the law of society. However, just because the protagonist, Freddie, mentions his mother’s presence as “nothing,” there is no soothing force for his adaptation to societal laws. Here, Freddie is subject to what Lacan sees as a minor prototype who lives in a society and yet is attached to his own rules, which is the first principle of male violence associated with this novel. Therefore, this article also tries to find answers for Freddie’s performance of male violence within the axis of psychoanalytic postulations elaborated on Lacan’s identity theory. (shrink)

This paper explores the relationships between perception, representation and appetition in Leibniz's later metaphysics, and defends four theses. First, for Leibniz perceptions are not the carriers of content, but they are identical to representational content. Second, Leibniz's appetitions are the carriers of content and he should be taken at his word when he declares, "Thought consists in conatus". Third, while it is true that for Leibniz representational content is determined by a species of mapping or function from representation to what (...) is represented, this is not the only component that determines representational content for Leibniz. The correspondence in terms of which Leibniz characterizes representation includes an ontological component, namely a lineage or trace from representation to represented object via God's creation, and appetitions constitute this trace. Finally, Leibniz's account of how ideas represent and how perceptions represent are distinct, and derivation plays a key role in how ideas represent. (shrink)

ABSTRACT This essay deals with the relation between representation, imitation, and the affects in Don Quixote. In so doing, it focuses on Cervantes’s Platonist poetics and his own views of imitation and the books of knighthood. Although most readers, translators, and critics have until now deemed Cervantes’s use of the word “republic” in Don Quixote unimportant, the word “república” or republic is in fact the entry point to Cervantes’ Platonist critique of the novels of knighthood, and his notions of writing, (...) imitation, and the emotions.

I demonstrate that analogies, both explicit and implicit, between Wittgenstein’s discussion of rituals, aesthetics, and psychoanalysis (and, indeed, his own philosophical methodology) suggest that he entertained the idea that Freud’s psychoanalytic project, when understood correctly—that is, as a descriptive project rather than an explanatory-hypothetical one—provides a “surveyable representation” (übersichtliche Darstellung) of certain psychological facts (as opposed to psychological concepts). The consequences of this account are that it offers an explanation of Wittgenstein’s admiration for and self-perceived affinity to Freud, as well (...) as of his apparent “know-nothing approach” to empirical psychology.

This is a critique of Lloyd's theory which appeared in his book, Simple Minds.

An important objection to signaling approaches to representation is that, if signaling behavior is driven by the maximization of usefulness, then signals will typically carry much more information about agent-dependent usefulness than about objective features of the world. This sort of considerations are sometimes taken to provide support for an anti-realist stance on representation itself. The author examines the game-theoretic version of this skeptical line of argument developed by Donald Hoffman and his colleagues. It is shown that their argument only (...) works under an extremely impoverished picture of the informational connections that hold between agent and world. In particular, it only works for cue-driven agents, in Kim Sterelny’s sense. In cases in which the agents’ understanding of what is useful results from combining pieces of information that reach them in different ways, and that complement one another, maximizing usefulness involves construing first a picture of agent-independent, objective matters of fact.

Although Hume appeals to the representational features of perceptions in many arguments in the Treatise, his theory of representation has traditionally been regarded as a weak link in his epistemology. In particular, it has proven difficult to reconcile Hume's use of representation as causal derivation and resemblance (the Copy Principle) with his use of representation in the context of impressions and abstract ideas. This paper offers a unified interpretation of representation in Hume that draws on the resources of Berkeley's doctrine (...) of signs. On this account, while the Copy Principle still occupies the core of Hume's "content empiricism," the manner in which any perception represents is understood as involving a relation of sign to thing signified. A sign/signified interpretation has the virtue of allowing Hume to remain within the strictures of his empiricism, while underwriting the various senses in which an impression or idea could possess content. Such an interpretation is not only adequate to account for the role that mental representations play in everyday behavior, but also for the purposes of elaborating the foundations of civil society that are Hume's concern in Book 3 of the Treatise.

In her landmark book, Language, Thought, and Other Biological Categories (Millikan1984),1 Ruth Garrett Millikan utilizes the idea of a biological function to solve philosophical problems associated with the phenomena of language, thought, and meaning. Language and thought are activities of biological organisms, according to Millikan, and we should treat them as such when trying to answer related philosophical questions. Of special interest is Millikan’s treatment of intentionality. Here Millikan employs the notion of a biological function to explain what it is (...) for one thing in nature, a bee dance (43), for example, to be about another, in this case, the location of a nectar source. My concern in this paper is to understand whether Millikan’s account of intentionality adequately explains how humans achieve reference, in language or thought, to individuals and groups in their environment. In bringing her theory of intentional content to bear on human activities, Millikan focuses largely on natural language. Thus, in what follows, I begin by laying out the biology-based principles that underlie Millikan’s theory of content, then proceed with an explanation of how the theory is to apply to natural language. As it appears, Millikan’s account of how content is determined for natural language terms and sentences rests on the determinacy of intentional content at the psychological level. This leads me to take a careful look at what Millikan says about the content of mental representations, in hopes of finding a sufficient basis there for the application of Millikan’s theory of content to natural language. Ultimately, I conclude that Millikan’s theory faces a problem of vacuity. If we approach the theory as a theory of intentional content, intended to explain the nature of reference, the theory is lacking in an extremely important respect: Millikan explains how it could be one of the biological functions of a mental or natural language term to refer, without telling us precisely what in the natural order constitutes the reference relation..

Deleuze’s philosophy of painting can be seen to pose certain challenges to a phenomenological approach to philosophy. While a phenomenological response to Deleuze’s philosophy is clearly needed, I show in this article how an approach taken in a recent paper by Christian Lotz proves inadequate. Lotz argues that through Deleuze’s refusal to accept the place of representation in art, he is unable to distinguish art from decoration, or to give a coherent account of how the content of art can be (...) represented. I show that this criticism emerges from a misreading of the place of representation in Deleuze’s philosophy. I will argue that by failing to take account of some of the key features of Deleuze’s wider ontology, such as the importance of both the virtual and the actual for his analysis of objects, Lotz’s critique proves unsuccessful. In particular, I want to show that Lotz’s criticisms rest on a failure to attend to the systematic nature of Deleuze’s philosophy, and in particular, the place of Deleuze’s analysis of Bacon within the system as a whole. I will further show that Lotz’s phenomenological defence commits the fallacy of petitio principii, assuming the validity of the phenomenological method in order to justify the phenomenological approach.

According to general wisdom, Carnap's quasianalysis is an ingenious but definitively flawed approach to epistemology and philosophy of science. I argue that this assessment is mistaken. Rather, Carnapian quasianalysis can be reconstructed as a special case of a general theory of structural representation. This enables us to exploit some interesting analogies of quasianalysis with the representational theory of measurement. It is shown how Goodman's well-known objections against the quasianalytical approach may be defused in the new framework. As an application, I (...) sketch how the thesis of empirical underdetermination of theories may be elucidated in the framework of quasianalysis. (shrink)

In this paper we argue that the different positions taken by Dyson and Feynman on Feynman diagrams’ representational role depend on different styles of scientific thinking. We begin by criticizing the idea that Feynman Diagrams can be considered to be pictures or depictions of actual physical processes. We then show that the best interpretation of the role they play in quantum field theory and quantum electrodynamics is captured by Hughes' Denotation, Deduction and Interpretation theory of models (DDI), where “models” are (...) to be interpreted as inferential, non-representational devices constructed in given social contexts by the community of physicists.

This paper develops a theory of analog representation. We first argue that the mark of the analog is to be found in the nature of a representational system’s interpretation function, rather than in its vehicles or contents alone. We then develop the rulebound structure theory of analog representation, according to which analog systems are those that use interpretive rules to map syntactic structural features onto semantic structural features. The theory involves three degree-theoretic measures that capture three independent ways in which (...) a system can be more or less analog. We explain how our theory improves upon prior accounts of analog representation, provides plausible diagnoses for novel challenge cases, extends to hybrid systems that are partially analog and partially symbolic, and accounts for some of the advantages and disadvantages of representing analogically versus symbolically.

Whether visual perceptual consciousness is gradable or dichotomous has been the subject of fierce debate in recent years. If perceptual consciousness is gradable, perceivers may have less than full access to—and thus be less than fully phenomenally aware of—perceptual information that is represented in working memory. This raises the question: In virtue of what can a subject be less than fully perceptually conscious? In this chapter, we provide an answer to this question, according to which inexact categorizations of visual input (...) may result in a representation of the visual information in working memory that is less than fully available to the perceiver, and of which the perceiver is therefore less than fully phenomenally aware. The latter proposal is a natural extension of a theory of perception we have proposed in previous works, namely, the template tuning theory (TTT). We argue that although TTT is compatible with both gradable and dichotomous conceptions of perceptual consciousness, the available empirical evidence favours a gradable conception of perceptual consciousness.

Humans possess two nonverbal systems capable of representing numbers, both limited in their representational power: the first one represents numbers in an approximate fashion, and the second one conveys information about small numbers only. Conception of exact large numbers has therefore been thought to arise from the manipulation of exact numerical symbols. Here, we focus on two fundamental properties of the exact numbers as prerequisites to the concept of EXACT NUMBERS : the fact that all numbers can be generated by (...) a successor function and the fact that equality between numbers can be defined in an exact fashion. We discuss some recent findings assessing how speakers of Munduruc (an Amazonian language), and young Western children (3-4 years old) understand these fundamental properties of numbers. (shrink)

This paper presents a novel theory of what it is that makes vision a representational affair. Vision is a process of representation; a fact that does not depend on it being "contentfull" or "indirect". Even if it turns out that vision is direct and/or intrinsically "contentless", it is nevertheless defined by features that decisively make it count as a process or representation. The phenomenology of vision is key here: as we see, we are directly presented with aspects of the environment (...) that are at various distances away from us. Through the process of vision, aspects of the environment that would otherwise still be unavailable or “absent”, are made (quasi-)available, or (quasi-)present. This already by itself makes vision deserving of the name ‘representational’, even if those distant aspects of the world are presented to us directly and contentless. In part I, I provide a bit of an overview of the relevant theoretical landscape, and I give my own take on how we may frame and approach some of the issues with respect to mental representation. Then, in part II, I argue that the representational features of vision must primarily be sought at the level of conscious experience. In part III, I elaborate on the two most common theories that are associated with the view that vision is ‘representational’, and proceed to show that there is in fact a third, more direct, way in which vision can be considered as essentially a process of representation. Finally, in part IV, I show that the kind of interaction problems that arise with the more traditional notions of representation also arise with this newer, more direct, notion. (shrink)

Although other animals can make simple tools, the expanded and complex material culture of humans is unprecedented in the animal kingdom. Tool making is a slow and late-developing ability in humans, and preschool children find making tools to solve problems very challenging. This difficulty in tool making might be related to the lack of familiarity with the tools and may be overcome by children's long term perceptual-motor knowledge. Thus, in this study, the effect of tool familiarity on tool making was (...) investigated with a task in which 5-to-6-year-old children (n = 75) were asked to remove a small bucket from a vertical tube. The results show that children are better at tool making if the tool and its relation to the task are familiar to them (e.g., soda straw). Moreover, we also replicated the finding that hierarchical complexity and tool making were significantly related. Results are discussed in light of the ideomotor approach. (shrink)

According to orthodox representationalism, perceptual states have constitutive veridicality or accuracy conditions. In defense of this view, several philosophers—most notably Tyler Burge—employ a realist strategy that turns on the purported explanatory ineliminability of representational posits in perceptual science. I argue that Burge’s version of the realist strategy fails as a defense of orthodox representationalism. However, it may vindicate a different kind of representationalism.

In IVP50S, Spinoza claims that “one who is moved to aid others neither by reason nor by pity is rightly called inhuman. For (by IIIP27) he seems to be unlike a man” (IVP50S). At first blush, the claim seems implausible, as it relies on the dubious assumption that beings will necessarily imitate the affects of conspecifics. In the first two sections of this paper, I explain why Spinoza accepts this thesis and show how this claim can be made compatible with (...) his account of representation. In the third and final section I offer an auxiliary defense of the thesis, showing that, according to Spinoza, to be human is to sociable, and sociability depends on the imitation of the affects.

The processing of time intervals in the sub- to supra-second range by the brain is critical for the interaction of primates with their surroundings in activities, such as foraging and hunting. For an accurate processing of time intervals by the brain, representation of physical time within neuronal circuits is necessary. I propose that time dimension of the physical surrounding is represented in the brain by different types of neuronal oscillators, generating spikes or spike bursts at regular intervals. The proposed oscillators (...) include the pacemaker neurons, tonic inputs, and synchronized excitation and inhibition of inter-connected neurons. Oscillators, which are built inside various circuits of brain, help to form modular clocks, processing time intervals or other temporal characteristics specific to functions of a circuit. Relative or absolute duration is represented within neuronal oscillators by “neural temporal unit,” defined as the interval between regularly occurring spikes or spike bursts. Oscillator output is processed to produce changes in activities of neurons, named frequency modulator neuron, wired within a separate module, represented by the rate of change in frequency, and frequency of activities, proposed to encode time intervals. Inbuilt oscillators are calibrated by (a) feedback processes, (b) input of time intervals resulting from rhythmic external sensory stimulation, and (c) synchronous effects of feedback processes and evoked sensory activity. A single active clock is proposed per circuit, which is calibrated by one or more mechanisms. Multiple calibration mechanisms, inbuilt oscillators, and the presence of modular connections prevent a complete loss of interval timing functions of the brain. (shrink)

One of the most significant characteristics of intentional states is the fact that they represent their intentional objects under selec￾tive aspects (or modes of presentation); that is, that they manifest an aspectual shape (Searle, 1992). Surprisingly however, although this remarkable feature is widely recognized little has been done to explain what makes representation aspect-relative in the first￾place. In this article I attempt to outline an answer to this question. I begin with a critique of Searle’s explanation of aspectual shape as (...) nchored in conscious experience. I argue next that, since to represent an object under an aspect is to represent it relative to a selective set of properties, the task – from the perspective of a theory of mental representation – is to explain what makes intentional states property-relative. It is then argued that while this task cannot be handled properly by standard (in particular computational-representational) theories of mental representa￾tion, a shift towards an action-based framework for theories of perception and representation promises to provide the key with which to unlock the puzzle.

David Lewis (1974, 1994/1999) proposed to reduce the facts about mental representation to facts about sensory evidence, dispositions to act, and rationality. Recently, Robert Williams (2020) and Adam Pautz (2021) have taken up and developed Lewis’s project in sophisticated and novel ways. In this paper, we aim to present, clarify, and ultimately object to the core thesis that they all build their own views around. The different sophisticated developments and defenses notwithstanding, we think the core thesis is vulnerable. We pose (...) a dilemma by considering the two sides of a current epistemological controversy over the relation between evidence and rational belief: permissivism vs. uniqueness. As we argue, the prospects for the Lewisian project look dim when either supposition is clearly made. (shrink)

Artificial intelligence (AI) is an area of computer science that emphasizes the creation of intelligent machines or software that work and reacts like humans, some of the computer activities with artificial intelligence are designed to include speech, recognition, learning, planning and problem solving. Deep learning is a collection of algorithms used in machine learning, it is part of a broad family of methods used for machine learning that are based on learning representations of data. Deep learning is used as (...) a technique to produce brain tumor detection and classification models using Magnetic Resonance Imaging (MRI) imaging for rapid and easy detection and identification of brain tumor. In this thesis, some ways and mechanisms will be reviewed to use deep learning techniques to produce a model for brain tumor detection. The goal is to find a good and effective way to detect brain tumor based on MRI to help the brain doctor in making decisions easily, accurately and rapidly. A recent report by the World Health Organization in February 2018 showed that the death rate from brain cancer or central nervous system (CNS) is the highest in the Asian continent. It is important to detect cancer early so that many of these lives can be saved. The model has been designed and implemented, including a dataset which consist of 10,000 images for brain tumor detection through the use of Deep learning algorithms based on neural networks. For testing, we have used our model, Inception, VGG16, MobileNet and ResNet models. The f-score accuracy we got for each model was as follows: Our model was 98.28, VGG16 was 99.86%, ResNet50 was 98.14%, MobileNet was 88,98%, and InceptionV3 was 99.88%. (shrink)

Regarding the connection between the Qur'an and the New Testament, we noted that Jesus Christ is often presented in the pages of the Qur'an as a moral model, along with his mother Mary. The events of the life of "Qur'an Jesus" are marked by marginal Christianity of the Monophysitism and by the Christian apocrypha circulating in the time of Muhammad in the Eastern space. The Qur'anic images of the figure of Jesus Christ present Him in His dignity as the Messiah, (...) the Prophet, the Divine Sign, and the Word of God. The Qur'anic exegesis proposes variants that diminish the image of Jesus in the Qur'an, reducing him to a mere Prophet, despite obvious Qur'anic texts that state otherwise. The Qur'an does nothing but reforms the Christian morality and change the sense to other meanings assessed by Muhammad and the Caliphs of Islam as suitable for the social life of Muslim communities. References to the Biblical Jesus Christ in the text of the Qur'an are generally divided into four main themes, which are discussed in detail in this article: Birth and Childhood; Teaching and Miracles; Nature and Status before God (Allah); The Death and the Resurrection.

UNRWA’s Mediation Process is a key element in the organization’s efforts to strengthen its internal justice system. The research aims to study the reality of mediator competencies, emotional intelligence and case characteristics variables, (UNRWA) Gaza. The research also aims at identifying the differences between respondents as attributed to their professional and personal traits of age, gender, educational level, distribution of department, dispute resolution experience and representation party. The researchers adopted mixed data collection methods; quantitative and qualitative. For qualitative, a semi-structured (...) interview was conducted with (9) officials including management, staff unions and expert external mediators. (63) Questionnaires were distributed to a systematic random sample population; (56) were received, with a response rate 88.9%. The results proved that there are no significant differences among respondents attributed to personal and professional traits of age, academic background, gender, department, years’ of experience, educational degree and representation party. The research has presented some recommendations concerning the factors affecting the mediation outcomes of workplace disputes resolution. The recommendations include: UNRWA should adopt mediation as a method to resolve disputes at workplace instead of following litigation before the courts, as many organizations today increasingly started to adopt mediation as a method to resolve disputes at workplace. This will help decreasing the high cost, non-flexibility, and threatening features of disputes and conflicts resolution before courts, as well as enhance the relationship between disputant parties. Mediators are essentially recommended to attend regular training such as guiding negotiation processes, employing group sessions properly, overcoming obstacles, summarizing & analytical skills and selecting emotional words and phrases, it is also important to encourage the mediation experts' training workshops and meetings. Regular training sessions will not only improve skills and abilities, but will also imply variety and flexibility. This leads to having competent qualified mediators who are able to resolve organization’s workplace disputes in a way, which satisfies the need of disputants. (shrink)

I demonstrate that analogies, both explicit and implicit, between Wittgenstein’s discussions of rituals, aesthetics, and aspect-perception, have important payoffs in terms of understanding his notion of a “surveyable representation” (übersichtliche Darstellung) as it applies to phenomena that are not exclusively grammatical in nature. In particular, I argue that a surveyable representation of certain anthropological and aesthetic facts allows us to see, qua form of aspect-perception, internal relations and formal connections, so that the inner nature of a ritual or the solution (...) of an aesthetic puzzle is exhibited. This particular form of seeing both explains why Wittgenstein thought that hypothetical explanations about the origins of a ritual are irrelevant to appreciating its meaning and elucidates his understanding of rituals, which involves seeing “internal relations” and “formal connections.” The upshots of the account for work in anthropology are discussed.

We discuss cases where subjects seem to enjoy conscious experience when the relevant first-order perceptual representations are either missing or too weak to account for the experience. Though these cases are originally considered to be theoretical possibilities that may be problematical for the higher-order view of consciousness, careful considerations of actual empirical examples suggest that this strategy may backfire; these cases may cause more trouble for first-order theories instead. Specifically, these cases suggest that (I) recurrent feedback loops to V1 (...) are most likely not the neural correlate of first-order representations for conscious experience, (II) first-order views seem to have a problem accounting for the phenomenology in these cases, and either (III) a version of the ambitious higher-order approach is superior in that it is the simplest theory that can account for all results at face value, or (IV) a view where phenomenology is jointly determined by both first-order and higher-order states. In our view (III) and (IV) are both live options and the decision between them may ultimately be an empirical question that cannot yet be decided. (shrink)

COVID science is being both done and circulated at a furious pace. While it is inspiring to see the research community responding so vigorously to the pandemic crisis, all this activity has also created a churning sea of bad data, conflicting results, and exaggerated headlines. With representations of science becoming increasingly polarized, twisted and hyped, there is growing concern that the relevant science is being represented to the public in a manner that may cause confusion, inappropriate expectations, and the (...) erosion of public trust. Here we explore some of the key issues associated with the representations of science in the context of the COVID-19 pandemic. Many of these issues are not new. But the COVID-19 pandemic has placed a spotlight on the biomedical research process and amplified the adverse ramifications of poor public communication. We need to do better. As such, we conclude with ten recommendations aimed at key actors involved in the communication of COVID-19 science, including government, funders, universities, publishers, media and the research communities.

In the Critique of the Power of Judgment, Kant introduces the notion of the reflective judgment and the a priori principle of purposiveness or systematicity of nature. He claims that the ability to judge objects by means of this principle underlies empirical concept acquisition and it is therefore necessary for cognition in general. In addition, he suggests that there is a connection between this principle and judgments of taste. Kant’s account of this connection has been criticized by several commentators for (...) the reason that it leads to the ‘everythingisbeautiful’ problem. In this paper I argue, contrary to these objections, that both finding an object beautiful and acquiring the concept represent the satisfaction of the same principle of nature’s purposiveness, which refers to the same cognitive need we have, that is, to systematize experience. I avoid the ‘everything is beautiful’ problem by arguing that aesthetic reflection refers to the synthesis of object’s individual and distinctive properties, while logical reflection refers to the synthesis of object’s general properties that it shares with other objects of its kind. Because aesthetic purposiveness is different from logical purposiveness, this allows for the possibility that we can have an object of cognition, without finding this object beautiful. (shrink)

Artificial intelligence (AI) is an area of computer science that emphasizes the creation of intelligent machines or software that work and react like humans. Some of the activities computers with artificial intelligence are designed for include, Speech, recognition, Learning, Planning and Problem solving. Deep learning is a collection of algorithms used in machine learning, It is part of a broad family of methods used for machine learning that are based on learning representations of data. Deep learning is a technique (...) used to produce Pneumonia detection and classification models using x-ray imaging for rapid and easy detection and identification of pneumonia. In this thesis, we review ways and mechanisms to use deep learning techniques to produce a model for Pneumonia detection. The goal is find a good and effective way to detect pneumonia based on X-rays to help the chest doctor in decision-making easily and accuracy and speed. The model will be designed and implemented, including both Dataset of image and Pneumonia detection through the use of Deep learning algorithms based on neural networks. The test and evaluation will be applied to a range of chest x-ray images and the results will be presented in detail and discussed. This thesis uses deep learning to detect pneumonia and its classification. (shrink)

The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis. Accordingly, we initiated the (...) development of the community-based Coronavirus Infectious Disease Ontology in early 2020. -/- As an Open Biomedical Ontology (OBO) library ontology, CIDO is open source and interoperable with other existing OBO ontologies. CIDO is aligned with the Basic Formal Ontology and Viral Infectious Disease Ontology. CIDO has imported terms from over 30 OBO ontologies. For example, CIDO imports all SARS-CoV-2 protein terms from the Protein Ontology, COVID-19-related phenotype terms from the Human Phenotype Ontology, and over 100 COVID-19 terms for vaccines (both authorized and in clinical trial) from the Vaccine Ontology. CIDO systematically represents variants of SARS-CoV-2 viruses and over 300 amino acid substitutions therein, along with over 300 diagnostic kits and methods. CIDO also describes hundreds of host-coronavirus protein-protein interactions (PPIs) and the drugs that target proteins in these PPIs. CIDO has been used to model COVID-19 related phenomena in areas such as epidemiology. The scope of CIDO was evaluated by visual analysis supported by a summarization network method. CIDO has been used in various applications such as term standardization, inference, natural language processing (NLP) and clinical data integration. We have applied the amino acid variant knowledge present in CIDO to analyze differences between SARS-CoV-2 Delta and Omicron variants. CIDO's integrative host-coronavirus PPIs and drug-target knowledge has also been used to support drug repurposing for COVID-19 treatment. -/- CIDO represents entities and relations in the domain of coronavirus diseases with a special focus on COVID-19. It supports shared knowledge representation, data and metadata standardization and integration, and has been used in a range of applications. (shrink)

According to the logical positivists, signs (words and pictures) of imaginary beings have no referent (Goodman). The semiotic theory behind this assumption is dualistic and Cartesian: signs vs. nonsigns as well as the mental vs. the material world are in fundamental opposition. Peirce’s semiotics is based on the premise of the sign as a mediator between such opposites: signs do not refer to referents, they represent objects to a mind, but the object of a sign can be existent or nonexistent, (...) a feeling or an idea, something merely imaginary or even something false. The paper examines the nature of imaginary, nonexistent, and nonfigurative objects, such as unicorns, phoenixes, or nonrepresentative paintings, and shows why verbal or visual representations of imaginary beings and even nonfigurative paintings, which seem to represent nothing, are fully developed signs with a variety of objects determining their representation.

A long series of studies in social psychology have shown that the explanations people give for their own behaviors are fundamentally different from the explanations they give for the behaviors of others. Still, a great deal of uncertainty remains about precisely what sorts of differences one finds here. We offer a new approach to addressing the problem. Specifically, we distinguish between two levels of representation ─ the level of linguistic structure (which consists of the actual series of words used in (...) the explanation) and the level of conceptual structure (which consists of the concepts these words are used to express). We then formulate and test hypotheses both about self-other differences in conceptual structure and about self-other differences in the mapping from conceptual structure to linguistic structure.

In some recent papers (G. ‘t Hooft and others), it has been argued that quantum mechanics can arise from classical cellular automata. Nonetheless, G. Shpenkov has proved that the classical wave equation makes it possible to derive a periodic table of elements, which is very close to Mendeleyev’s one, and describe also other phenomena related to the structure of molecules. Hence the classical wave equation complements Schrödinger’s equation, which implies the appearance of a cellular automaton molecular model starting from classical (...) wave equation. The other studies show that the microworld is constituted as a tessellation of primary topological balls. The tessellattice becomes the origin of a submicrospic mechanics in which a quantum system is subdivided to two subsystems: the particle and its inerton cloud, which appears due to the interaction of the moving particle with oncoming cells of the tessellattice. The particle and its inerton cloud periodically change the momentum and hence move like a wave. The new approach allows us to correlate the Klein-Gordon equation with the deformation coat that is formed in the tessellatice around the particle. The submicroscopic approach shows that the source of any type of wave movements including the Klein-Gordon, Schrödinger, and classical wave equations is hidden in the tessellattice and its basic exciations – inertons, carriers of mass and inert properies of matter. We also discuss possible correspondence with Konrad Zuse’s calculating space. (shrink)
