In a remarkable development, I have constructed a new definition for a self-delimiting universal Turing machine (UTM) that is easy to program and runs very quickly. This provides a new foundation for algorithmic information theory (AIT), which is the theory of the size in bits of programs for selfdelimiting UTM's. Previously, AIT had an abstract mathematical quality. Now it is possible to write down executable programs that embody the constructions in the proofs of theorems. So AIT goes from dealing (...) with remote idealized mythical objects to being a theory about practical down-to-earth gadgets that one can actually play with and use. (shrink)

This study investigates the joint influences of three factors on the discovery of new word‐like units in a continuous artificial speech stream: the statistical structure of the ongoing input, the initial word‐likeness of parts of the speech flow, and the contextual information provided by the earlier emergence of other word‐like units. Results of an experiment conducted with adult participants show that these sources of information have strong and interactive influences on word discovery. The authors then examine the (...) ability of different models of word segmentation to account for these results. PARSER (Perruchet & Vinter, 1998) is compared to the view that word segmentation relies on the exploitation of transitional probabilities between successive syllables, and with the models based on the Minimum Description Length principle, such as INCDROP. The authors submit arguments suggesting that PARSER has the advantage of accounting for the whole pattern of data without ad‐hoc modifications, while relying exclusively on general‐purpose learning principles. This study strengthens the growing notion that nonspecific cognitive processes, mainly based on associative learning and memory principles, are able to account for a larger part of early language acquisition than previously assumed.

Critical reasoning (CR) when confronted with contradictory information from multiple sources is a crucial ability in a knowledge-based society and digital world. Using information without critically reflecting on the content and its quality may lead to the acceptance of information based on unwarranted claims. Previous personal beliefs are assumed to play a decisive role when it comes to critically differentiating between assertions and claims and warranted knowledge and facts. The role of generic epistemic beliefs on critical (...) stance and attitude in reflectively dealing with information is well researched. Relatively few studies have been conducted on the influence of domain-specific beliefs, i.e. beliefs in relation to specific content encountered in a piece of information or task, on the reasoning process, and on how these beliefs may affect the information-processing and decision-making processes. This study focuses on students’ task- and topic-related beliefs that may influence their reasoning when dealing with multiple and partly contradictory sources of information. To validly assess CR among university students, we used a newly developed computer-based performance assessment in which the students were confronted with an authentic task which contains theoretically defined psychological stimuli for measuring CR. To investigate the particular role of task- and topic-related beliefs on CR, a purposeful sample of 30 university students took part in a performance assessment and then were interviewed immediately afterwards. In the semi-structured cognitive interviews, the participants’ task-related beliefs were assessed. Based on qualitative analyses of the interview transcripts, three distinct profiles of decision-making among students have been identified. More specifically, the different types of students’ beliefs and attitudes derived from the cognitive interview data suggest their influence on information processing, reasoning approaches and decision-making. The results indicated that the students’ beliefs had an influence on their selection, critical evaluation and use of information as well as on their reasoning processes and final decisions. (shrink)

This article will address the issue of using understandings of psychodynamic interrelations as a means to grasp how social and cultural dynamics are processed individually and collectively in narratives. I apply the two theoretically distinct concepts of inter- and intrasubjectivity to gain insight into how social and cultural dynamics are processed as subjective experiences and reflected in the interrelational space created in narrative interviews with trainee social educators. By using a combination of interactionist theory and psychosocial theory in the analysis (...) of an interview with a student of social education, I demonstrate how the often conflicting demands and expectations are being played out in the interrelational tension between the researcher (myself) and the interviewee or narrator. In a confrontation with "inner" expectations and concerns regarding a future profession and one's ability to cope, and the "outer" socially and culturally embedded discourses as they are played out in the objectives of self-development and education, the narrative about a forthcoming internship is filled with tension and contradiction. In this article I will demonstrate how such tensions and contradictions are valuable sources of information in understanding the process of becoming a social educator. (shrink)

The paper examines the realignment of the legal sources in an information society, by considering first of all the differences with the previous system of sources, dubbed as the “Westphalian model”. The current system is tripartite, rather than bipartite, for the sources of transnational law should be added to the traditional dichotomy between national and international law. In addition, the system is dualistic, rather than monistic, because the tools of legal constructivism, such as codes or statutes, (...) have to be complemented with the rules of customary law and contracts. In light of the canonical version of the law as a set of commands enforced through the threat of physical sanctions, however, two further novelties must be stressed, namely the soft law-tools of governance as a source of the system and the aim to embed normative constraints into technology, in order to enforce the law through the use of filtering systems, self-enforcing technologies, etc. This latter approach impacts on functions and requirements of the system, by transferring the normative side of the law from the traditional “ought to” of legal commands to what actually is on the basis of automatic techniques, thus affecting the very notion of source. The overall aim of the paper is to show that rearrangements of the legal sources are intertwined with redistributions of power and hence, a normative standpoint is needed, so as to determine whether scholars can obtain the solution that best justifies the integrity of the law before its hard cases, or the answer is a reasonable compromise between many conflicting interests.

Though Aristotle is universally acknowledged as having a mighty influence on the history of philosophy, large parts of his writings are often thought to be interesting to nobody except the historian. This includes those treatises known as the theoretical works (preeminently the Metaphysics, Physics, De Anima, and Posterior Analytics). However, the contributions in this book show that these old treatises are still profound resources for philosophical inquiry. Not only do they inform us about the origins of our ideas, but equally (...) they express insights that always stand in need of reinterpretation, and thus challenge our understanding. That challenge to understanding - and ultimately the desire for self-understanding, the desire to know what stands at the source of thinking itself - this was at the heart of the Greek ideal of philosophy, and some would say that this is still the task of the discipline. The essays included here cover a wide range of topics, including Aristotle's treatment of non-contradiction, the tension between his conceptions of knowledge and being, the complexity of the term 'potency,' and the relation between psychology and physics.

This short work presents a popular fringe theory as a source of case studies for use in teaching informal logic in an introductory course. It puts forward ancient astronaut theory as the candidate source, together with a characterization of why it fits the bill. The televised material associated with that theory is well suited to being used as case studies given that they are easy to follow, contain a surprising number of arguments and fallacies, and keep students reliably engaged. The (...) paper includes an overview of the forms of argumentation and fallacies that these cases may be used to teach, along with a sketch of how to best implement them in the classroom. (shrink)

Perceivers generally show a poor ability to detect changes, a condition referred to as “Change Blindness” . They are, in addition, “blind to their own blindness”. A common explanation of this “Change Blindness Blindness” is that it derives from an inadequate, “photographical” folk-theory about perception. This explanation, however, does not account for intra-individual variations of CBB across trials. Our study aims to explore an alternative theory, according to which participants base their self-evaluations on two activity-dependent cues, namely search time and (...) perceived success in prior trials. These cues were found to influence self-evaluation in two orthogonal ways: success-feedback influenced self-evaluation in a global, contextual way, presumably by recalibrating the norm of adequacy for the task. Search time influenced it in a local way, predicting the success of a given trial from its duration. (shrink)

Using data from the China Family Panel Studies, this paper investigates the effects of Internet use on residents’ risk attitudes. Both Generalized Ordered Logit Model and Logit model are used to identify the effects of Internet use. The results reveal an association between Internet use and increases in both subjective and objective risk preferences that remains even after we adjust for possible endogeneity. The heterogeneity analysis also reveals that these impacts are different among groups with different reasons for Internet use (...) and different personal characteristics. Our study expands the research on the effects of Internet on people’s concepts from the micro perspective and suggests that while promoting the application of information technology we should also pay attention to the individual characteristics of residents so that we can better share the “digital dividend” brought by the popularization of information technology in the whole society.

All information results from a process, intrinsic to living beings, of info-autopoiesis or information self-production; a sensory commensurable, self-referential feedback process immanent to Bateson’s ‘difference which makes a difference’. To highlight and illustrate the fundamental nature of the info-autopoietic process, initially, two simulations based on one-parameter feedback are presented. The first, simulates a homeostatic control mechanism (thermostat) which is representative of a mechanistic, cybernetic system with very predictable dynamics, fully dependent on an external referent. The second, simulates a (...) homeorhetic process, inherent to biological systems, illustrating a self-referenced, autonomous system. Further, the active incorporation/interference of viral particles by prokaryotic cells and the activation of CRISPR-Cas can be understood as info-autopoiesis at the most fundamental cellular level, as well as constituting a planetary network of self-referenced information. Moreover, other examples of the info-autopoietic nature of information are presented to show the generality of its applicability. In short, info-autopoiesis is a recursive process that is sufficiently generic to be the only basis for information in nature: from the single cell, to multi-cellular organisms, to consideration of all types of natural and non-natural phenomena, including tools and artificial constructions.

We develop a probabilistic criterion for belief expansion that is sensitive to the degree of contextual fit of the new information to our belief set as well as to the reliability of our information source. We contrast our approach with the success postulate in AGM-style belief revision and show how the idealizations in our approach can be relaxed by invoking Bayesian-Network models.

Image has been considered an influential factor in tourists’ perceptions and evaluations of a destination. This paper analyzes the formation of the tourist destination image of Segóbriga Archaeological Park, a cultural destination of great heritage value, located in the province of Cuenca (Spain). The image is analyzed using a multidimensional approach, considering not only its cognitive and affective components, but also the unique-image component. The latter has received less attention in the literature and is a novelty in the context of (...) this type of cultural destination. The results show that this component is essential to the overall image of an archaeological destination and that it is not influenced by information sources. PLS-SEM was used. (shrink)

Looks into evaluation of information provision probability from different sources, based on use of linguistic variables. Formation of functions appurtenant for its unclear variables provides for adoption of decisions by the decision maker, in conditions of nonprobabilistic equivocation. The development of market relations in Ukraine increases the independence and responsibility of enterprises in justifying and making management decisions that ensure their effective, competitive activities. As a result of the analysis, it is determined that the condition of economic facilities (...) can be described and determined by the decision-maker, in the presence of the necessary information. The confidence of the decision-maker in the information received is different and the decisions made have a correspondingly different level of information risk. It is important to substantiate the procedure for assessing the numerical extent of information risk in decision-making based on the information obtained in conditions of uncertainty. The use of a linguistic variable in the processing of expert data presented in the form of a matrix of binary relations of values of the membership function, which allowed to move to further processing of knowledge to support decision-making in the management of industrial, commercial, financial and other activities. As a mathematical model for estimating the numerical measure of information risk when making decisions based on the information obtained in conditions of non-stochastic uncertainty, a model has been developed to model natural language uncertainties, which differs from existing ones by formalizing knowledge taking into account uncertainty of input information. Making such a clear decision in a fuzzy environment has appropriate values of effectiveness and risk. The paper proposes all the functions and accessories of indicators of both quantitative nature and qualitative nature to bring their values in the field of definition to one scale. Then the indicator of the effectiveness of decision-making will be a measure of the clarity of the cross-section of fuzzy subsets, which correspond to the introduced indicators of information risk. The condition of economic facilities can be described and determined by the decision-maker, if the necessary information is available. Decision-making on thenumerical measure of information risk must be determined by a set of basic indicators, which can be both quantitative and qualitative in nature. Predictive values of indicators should be determined in conditions of nonstochastic uncertainty. In this case, the indicators of a quantitative nature can be determined by fuzzy triangular numbers, which implement a high level of confidence in the subjective judgments of experts. Indicators of qualitative nature should be presented in linguistic variables. The values of the indicators of qualitative nature that are predicted must be considered for all fuzzy variable terms-sets of linguistic variables introduced into consideration. For any fuzzy variable, the introduction to the consideration of a clear set of values as carriers of the α-level of its membership function allows to reduce to a single interpretation of the predicted values of indicators of quantitative and qualitative nature in terms of non-stochastic uncertainty.

Background/ObjectiveJudicial decisions must rest on formal reasoning. Nevertheless, informal reasoning sources were observed in judicial judgment making. Literature has identified sexual aggression cases as the most favorable for informal reasoning. Thus, a field study was designed with the aim of assessing the incidence and effects of cognitive and motivational biases in judicial agents in a case to rape to a woman.MethodsAs for this, Chilean judicial agents assessed an allegation of sexual assault in a case where the perpetrator was known (...) or unknown to the victim. The judicial agents answered to a measure of the myths about sexual aggression, the attribution of responsibility to complainant, the attribution of responsibility to accused, the attribution of credibility to the complainant testimony, the attribution of a nature of a rape to the alleged facts and an estimation of the probability of false/unfounded accusations.ResultsThe results revealed an estimation of false/unfounded accusations of sexual aggression significantly higher than the mean of the best estimates, but into the upper limit of the best estimates; that the studied population did not share, in general, the myths about sexual aggression; and that the sources of attributional biases were driven in favor and against the complainant. Nevertheless, the case study showed that a large number of judicial agents participated of an overestimation of the probabilities of false or unfounded allegations, and of the myths about sexual aggressions and of attributional biases against the complainant.ConclusionIn conclusion, informal reasoning sources were observed in judicial agents when only formal reasoning should prevail. Thus, judicial agents should be trained to control these sources of bias substituting them by formal reasoning. (shrink)

This book provides an introduction to semiotic through readings from classic works in the field. In contrast with descriptions of communication systems based on the methods of empirical linguistics and interpretive studies of artistic means of communication, this text delimits semiotic as a logical study with its foundations in the theories of Greek and medieval logicians and the classifications of Charles Peirce. Clarke defines semiotic as the general theory that attempts to specify the logical features of signs and the similarities (...) and differences among the great variety of forms they can take. He samples readings from the field and explains their role in the development of the subject. His discussion begins with the treatment of signs in the early Greek period, starting with Aristotle and ending with Sextus Empiricus. He proceeds through an examination of the works of the medieval philosophers Augustine and Ockham, of post-Cartesians Arnauld, Reid, and Berkeley, and of the founder of modern semiotic, Charles Peirce. Final chapters cover the major writings of those who have shaped the development of the field in the twentieth century: Morris, Skinner, and Carnap of the behavioral school of semiotic; Saussure, Hjelmslev, Barthes, and Jakobson of the Continental school; and the analytic philosophers Strawson, Bennett, Lewis, and Goodman. Each selection, accompanied by Clarke’s commentary, works to restore the links between semiotic and medieval discussions of signs that inform this work. Throughout, Clarke offers students a history that is also an aid for charting a course through the present-day maze of divergent approaches and conflicting methodologies. (shrink)

Virtues are habits of character that advance excellence in all of ones endeavors. In the Aristotelian formulation, training in the virtuesis driven by a sense of the “good,” that is, by a widely shared agreement on the components of a good society and on the roles (and appropriate virtues or excellencies) of the “social animals” that energize that society. In the modern era, however, a strong sense of community has been much diminished. Freedom from the restraints of the Church and (...) other social institutions and an emphasis on individual autonomy has fostered a different ethical perspective, a perspective in which the market enters importantly into one’s conception of the good. Does the market generate virtues which in turn sustain it? What guides the development of virtue in market economies that are entering the “information superhighway,” and a new millennium as well?

Summary Gessner's sources for the pictures in his Historia animalium were varied in kind and in quality. This should be understood within the larger context of the Historia animalium in which Gessner sought to collect everything ever written about animals, an enterprise that could not be completed by a single individual. Just as Gessner did not distil or reduce similar texts but retained these as well as contradictory or false textual descriptions as part of a repository of knowledge, so (...) also Gessner included several pictures of the same animal, false or badly drawn ones, and juxtaposed erroneous and ?true? images. The attribution of images to witnesses and correspondences also reflects Gessner's strategy to credit those who drew his attention to new information first. The sources of Gessner's images thus indicate how his visual world encompassed more than the strictly self-observable, and a pictorial practice that was intimately connected with textual traditions and intellectual networks.

In lieu of an abstract, here is a brief excerpt of the content:The Sources of MemoryJeffrey Andrew Barash“What does it mean to remember?” This question might seem commonplace when it is confined to the domain of events recalled in past individual experience; but even in this restricted sense, when memory recalls, for example, a first personal encounter with birth or with death, the singularity of the remembered image places the deeper possibilities of human understanding in relief. Such experiences punctuating (...) everyday life highlight the central place of memory as a source of human identity.With a few notable exceptions, such as Henri Bergson or Maurice Halb-wachs, this central role of memory was rarely a topic of interest in the theoretical orientations of our century. It played only a peripheral role in the different philosophical orientations and in the human sciences of this century until, very recently, new attempts have been made to comprehend the significance of memory, above all in the fields of intellectual history and philosophy. Without dealing exhaustively with the bibliography of works on memory, I will mention what seem to me to be the signs of a recent renewal of questioning in this area of interest to historians and philosophers alike. This will lead me to the specific problem I will address in the pages that follow.One of the chief sources of the historian’s recent interest in memory has been the historians’ conflict (Historikerstreit) of the 1980s concerning the interpretation of the German and European past since the rise to power of Nazism and in the aftermath of World War II. As the generations who lived through and—from a given perspective—remembered these events increasingly disappear, the question concerning their precise historical meaning has reemerged with a new urgency. In this vein, for example, as the relatively new periodical History and Memory: Studies in the Representation of the Past and the collection of essays Probing the Limits of Representation: Nazism and the “Final Solution,” edited by Saul Friedlander, amply attest, the relation of memory to historical narrative is as important as it is problematic: to the extent that eyewitness memory claims a status of objectivity beyond the fictional sphere of [End Page 707] the imagination, its role in informing historical narrative involves the very issue of objectivity itself. 1Independently of this query concerning the relation of memory and history in recent scholarship focusing on the twentieth century, a number of studies have attempted to place the idea of memory in historical perspective during premodern periods. In this regard, we may cite Janet Coleman’s recently published work, Ancient and Medieval Memories: Studies in the Reconstruction of the Past and Mary Carruthers’s treatment of the subject of memory in the medieval period in The Book of Memory: A Study of Memory in Medieval Culture. 2 A number of other recent works in the field of intellectual history have attempted to grapple with the intriguing problem of the historicity of the phenomenon of memory in the West. This idea of the historicity of memory has been inspired at least in part by Pierre Nora’s essay, “Between Memory and History,” which introduced the multi-volume series he directed, Les Lieux de mémoire. In this vein, Patrick H. Hutton’s History as an Art of Memory, Matt K. Matsuda’s The Memory of the Modern, and Richard Terdiman’s Present Past: Modernity and the Memory Crisis all center on the historical transforma-tions to which, according to the different perspectives of their works, “memory” has been subject. 3 Like Nora, they link this historicity of the social and cultural role of memory to the radical transformations that Western civilization has undergone in the modern period.In a philosophical perspective David Farrell Krell’s work, Of Memory, Reminiscence, and Writing: On the Verge, presents a very different idea of the phenomenon of memory. 4 Where the intellectual historians of modernity stress the mutations in the role of memory, Krell, following in the footsteps of Jacques Derrida, emphasizes one essential line of continuity that, to his mind, has tied [End Page 708] together the tradition of philosophical reflection on memory from Plato and Aristotle up until Freud: the metaphoric reference to memory as the faculty...

When government officials can look you in the eye and invoke the Federal Freedom of Information Act, they know full well that they have donned a cloak of invisibility. They are saying, in effect, "You can't touch me," and they are calculating that you will get the message and go away. Worse yet, they are putting a premium on "access" journalism—they are elevating the importance of access, of authorized leaks, of journalists currying favor with the right government officials to (...) get information and to get information quickly, when they are on deadline and they need answers. Simply put, if journalists cannot rely on being able to go to source documents in a reasonably fast way, they are in a terribly weakened position when it comes to actually dealing day-in and day-out with high government officials.

A consumer health information system must be able to comprehend both expert and non-expert medical vocabulary and to map between the two. We describe an ongoing project to create a new lexical database called Medical WordNet (MWN), consisting of medically relevant terms used by and intelligible to non-expert subjects and supplemented by a corpus of natural-language sentences that is designed to provide medically validated contexts for MWN terms. The corpus derives primarily from online health information sources targeted (...) to consumers, and involves two sub-corpora, called Medical FactNet (MFN) and Medical BeliefNet (MBN), respectively. The former consists of statements accredited as true on the basis of a rigorous process of validation, the latter of statements which non-experts believe to be true. We summarize the MWN / MFN / MBN project, and describe some of its applications. (shrink)

Information is a peculiar quantity. Unlike matter and energy, which are conserved by the laws of physics, the aggregation of knowledge from many sources can in fact produce more information (synergy) or less (redundancy) than the sum of its parts. This feature can endow groups with problem‐solving strategies that are superior to those possible among noninteracting individuals and, in turn, may provide a selection drive toward collective cooperation and coordination. Here we explore the formal properties of (...) class='Hi'>information aggregation as a general principle for explaining features of social organization. We quantify information in terms of the general formalism of information theory, which also prescribes the rules of how different pieces of evidence inform the solution of a given problem. We then show how several canonical examples of collective cognition and coordination can be understood through principles of minimization of uncertainty (maximization of predictability) under information pooling over many individuals. We discuss in some detail how collective coordination in swarms, markets, natural language processing, and collaborative filtering may be guided by the optimal aggregation of information in social collectives. We also identify circumstances when these processes fail, leading, for example, to inefficient markets. The contrast to approaches to understand coordination and collaboration via decision and game theory is also briefly discussed. (shrink)
