Previous research reported that college students' symbolic addition and subtraction fluency improved after training with non-symbolic, approximate addition and subtraction. These findings were widely interpreted as strong support for the hypothesis that the Approximate Number System (ANS) plays a causal role in symbolic mathematics, and that this relation holds into adulthood. Here we report four experiments that fail to find evidence for this causal relation. Experiment 1 examined whether the approximate arithmetic training effect exists within a shorter (...) training period than originally reported (2 vs 6 days of training). Experiment 2 attempted to replicate and compare the approximate arithmetic training effect to a control training condition matched in working memory load. Experiments 3 and 4 replicated the original approximate arithmetic training experiments with a larger sample size. Across all four experiments (N = 318) approximate arithmetic training was no more effective at improving the arithmetic fluency of adults than training with control tasks. Results call into question any causal relationship between approximate, non-symbolic arithmetic and precise symbolic arithmetic. (shrink)

Some normative theorists believe that there is a principled moral reason not to retain benefits realized by injustice or wrongdoing. However, critics have argued that this idea is implausible. One purported problem is that the idea lacks an obvious rationale and that attempts to provide one have been unconvincing. This paper articulates and defends the idea that the principled reason in question has an expressive quality: it gets its reason-giving force from the symbolic aptness of such an act (...) as an expressive response to wrongdoing. The paper thus argues that at least in a certain subset of cases, renouncing benefits realized by injustice amounts to a powerful and uniquely apt expression of protest against the disrespect for the victim that is implied by the wrongdoer’s actions. The paper shows how this idea can inform the question of reparations for slavery and its aftermath in the United States. Lastly it develops an important objection to the argument presented and gives an account of how this objection can be met. (shrink)

This paper examines the logic and morality of the German Stem Cell Act of 2002. After a brief description of the law’s scope and intent, its ethical dimensions are analysed in terms of symbolic threats, indirect consequences, and the encouragement of immorality. The conclusions are twofold. For those who want to accept the law, the arguments for its rationality and morality can be sound. For others, the emphasis on the uniqueness of the German experience, the combination of absolute and (...) qualified value judgments, and the lingering questions of indirect encouragement of immoral activities will probably be too much.

This article examined the effects of body–object interaction (BOI) on semantic processing. BOI measures perceptions of the ease with which a human body can physically interact with a word's referent. In Experiment 1, BOI effects were examined in 2 semantic categorization tasks (SCT) in which participants decided if words are easily imageable. Responses were faster and more accurate for high BOI words (e.g., mask) than for low BOI words (e.g., ship). In Experiment 2, BOI effects were examined in a semantic (...) lexical decision task (SLDT), which taps both semantic feedback and semantic processing. The BOI effect was larger in the SLDT than in the SCT, suggesting that BOI facilitates both semantic feedback and semantic processing. The findings are consistent with the embodied cognition perspective (e.g., Barsalou's, 1999, Perceptual Symbols Theory), which proposes that sensorimotor interactions with the environment are incorporated in semantic knowledge.

Humans are often extraordinary at performing practical reasoning. There are cases where the human computer, slow as it is, is faster than any artificial intelligence system. Are we faster because of the way we perceive knowledge as opposed to the way we represent it? -/- The authors address this question by presenting neural network models that integrate the two most fundamental phenomena of cognition: our ability to learn from experience, and our ability to reason from what has been learned. This (...) book is the first to offer a self-contained presentation of neural network models for a number of computer science logics, including modal, temporal, and epistemic logics. By using a graphical presentation, it explains neural networks through a sound neural-symbolic integration methodology, and it focuses on the benefits of integrating effective robust learning with expressive reasoning capabilities. -/- The book will be invaluable reading for academic researchers, graduate students, and senior undergraduates in computer science, artificial intelligence, machine learning, cognitive science and engineering. It will also be of interest to computational logicians, and professional specialists on applications of cognitive, hybrid and artificial intelligence systems. (shrink)

The last two decades have produced unprecedented successes in the fields of artificial intelligence and machine learning (ML), due almost entirely to advances in deep neural networks (DNNs). Deep hierarchical memory networks are not a novel concept in cognitive science and can be traced back more than a half century to Simon's early work on discrimination nets for simulating human expertise. The major difference between DNNs and the deep memory nets meant for explaining human cognition is that the latter are (...) symbolic networks meant to model the dynamics of human memory and learning. Cognition-inspired symbolic deep networks (SDNs) address several known issues with DNNs, including (1) learning efficiency, where a much larger number of training examples are required for DNNs than would be expected for a human; (2) catastrophic interference, where what is learned by a DNN gets unlearned when a new problem is presented; and (3) explainability, where there is no way to explain what is learned by a DNN. This paper explores whether SDNs can achieve similar classification accuracy performance to DNNs across several popular ML datasets and discusses the strengths and weaknesses of each approach. Simulations reveal that (1) SDNs provide similar accuracy to DNNs in most cases, (2) SDNs are far more efficient than DNNs, (3) SDNs are as robust as DNNs to irrelevant/noisy attributes in the data, and (4) SDNs are far more robust to catastrophic interference than DNNs. We conclude that SDNs offer a promising path toward human-level accuracy and efficiency in category learning. More generally, ML frameworks could stand to benefit from cognitively inspired approaches, borrowing more features and functionality from models meant to simulate and explain human learning.

The paper distinguishes between two kinds of products, `symbolic' and `substantive'. While substantive products confer welfare utility in the sense of pecuniary benefits, symbolic products accord self-regarding utility. Symbolic products enter the utility function in a way which differs from substantive ones. The paper distinguishes among three kinds of symbolic products and proposes that each has a distorted form. If symbolic products result from forward-looking evaluation, they act as `prestige goods' which please admiration or, (...) when distorted, as `vanity goods' which satiate pretentiousness. When symbolic products originate from forward-looking action, they act as `pride goods' which satisfy respect or, when distorted, as `deference goods' which indulge pomposity. When symbolic products arise from backward-looking evaluation, they act as `identity goods' which enhance dignity or, when distorted, as `reification goods' which gratify reverence. (shrink)

In ‘‘Why brains matter: an integrational perspective on The Symbolic Species’’ Cowley (2002) [Language Sciences 24, 73–95] suggests that Deacon pictures brains as being able to process words qua tokens, which he identifies as the theory’s Achilles’ heel. He goes on to argue that Deacon’s thesis on the co-evolution of language and mind would benefit from an integrational approach. This paper argues that Cowley’s criticism relies on an invalid understanding of Deacon’s use the concept of ‘‘symbolic reference’’, which (...) he appropriates from Peirce’s semiotic. Peirce’s analysis as well as Deacon’s appropriation will be examined in detail. Consequently it will be argued that an integrationist reading would add very little to Deacon’s core thesis. (shrink)

Human cognition and behavior are dominated by symbol use. This paper examines the social learning strategies that give rise to symbolic communication. Experiment 1 contrasts an individual-level account, based on observational learning and cognitive bias, with an inter-individual account, based on social coordinative learning. Participants played a referential communication game in which they tried to communicate a range of recurring meanings to a partner by drawing, but without using their conventional language. Individual-level learning, via observation and cognitive bias, was (...) sufficient to produce signs that became increasingly effective, efficient, and shared over games. However, breaking a referential precedent eliminated these benefits. The most effective, most efficient, and most shared signs arose when participants could directly interact with their partner, indicating that social coordinative learning is important to the creation of shared symbols. Experiment 2 investigated the contribution of two distinct aspects of social interaction: behavior alignment and concurrent partner feedback. Each played a complementary role in the creation of shared symbols: Behavior alignment primarily drove communication effectiveness, and partner feedback primarily drove the efficiency of the evolved signs. In conclusion, inter-individual social coordinative learning is important to the evolution of effective, efficient, and shared symbols. (shrink)

We examine over 100 top performing Canadian firms in visibly polluting industries as we seek to answer four research questions: What specific environmental issues are firms addressing? How do these issues differ between industries? Are both symbolic and substantive actions financially beneficial? Does green-washing, measured as the difference between symbolic and substantive action, and/or green-highlighting, measured as the combined effect of symbolic and substantive actions, pay? We find that substantive actions of environmental issues (green walk) neither harm (...) nor benefit firms financially, but symbolic actions (green talk) are negatively related to financial performance. We also find that green-washing (discrepancy between green talk and green walk) has a negative effect on financial performance and green-highlighting (concentrated efforts of the talk and walk) has no effect on financial performance. In this article, we provide explanations of our findings and put forth future research directions. (shrink)

The business ethics field contains a number of explanations for the imagination’s influence on decision-making. This has benefited moral theorizing because approaches that utilize the imagination tend to acknowledge important biological and psychological forces that influence the way we understand situations, develop strategies for problem-solving, and choose courses of action. But, I argue, the broad range of approaches has also served as an obstacle to theory development in the field. Given the variety of theoretical and disciplinary approaches, coupled with the (...) diversity of applications, it would be fair to judge the current state of theory as fractured. To bring focus to theory development, this conceptual study of the moral imagination is grounded in the work of one discipline, one theorist, one text: Plato’s Republic. The primary outcome of this study is the demonstration of the conditions under which the imagination serves to augment and support rationality rather than serving as an impediment. The systematic nature of Plato’s theory aids in the formation of more coherent conceptual grounding than currently available in the field. A final contribution of this study is the positioning of Plato as a proper beginning or foundation to any further theory development in the moral imagination. (shrink)

On both sides of the debate on the use of embryos in stem cell research, and in reproductive technologies more generally, rhetoric and symbolic images have been evoked to influence public opinion. Human embryos themselves are described as either “very small human beings” or “small clusters of cells.” The intentions behind the use of these phrases are clear. One description suggests that embryos are already members of our community and share with us a right to life or at least (...) respectful treatment, whereas the other focuses on the differences between embryos and adult human beings with normal capacities, that is, their lack of sentience and of personal identity. The research on stem cells has been nicknamed “Frankenstein science” or presented as “research that could stop Parkinson disease.” Again, one description reminds us of scary science-fiction scenarios where the scientist is guilty of “playing God,” whereas the other description highlights the worth and potential benefits of the research outcomes.

Abduction is or subsumes a process of inference. It entertains possible hypotheses and it chooses hypotheses for further scrutiny. There is a large literature on various aspects of non-symbolic, subconscious abduction. There is also a very active research community working on the symbolic (logical) characterisation of abduction, which typically treats it as a form of hypothetico-deductive reasoning. In this paper we start to bridge the gap between the symbolic and sub-symbolic approaches to abduction. We are interested (...) in benefiting from developments made by each community. In particular, we are interested in the ability of non-symbolic systems (neural networks) to learn from experience using efficient algorithms and to perform massively parallel computations of alternative abductive explanations. At the same time, we would like to benefit from the rigour and semantic clarity of symbolic logic. We present two approaches to dealing with abduction in neural networks. One of them uses Connectionist Modal Logic and a translation of Horn clauses into modal clauses to come up with a neural network ensemble that computes abductive explanations in a top-down fashion. The other combines neural-symbolic systems and abductive logic programming and proposes a neural architecture which performs a more systematic, bottom-up computation of alternative abductive explanations. Both approaches employ standard neural network architectures which are already known to be highly effective in practical learning applications. Differently from previous work in the area, our aim is to promote the integration of reasoning and learning in a way that the neural network provides the machinery for cognitive computation, inductive learning and hypothetical reasoning, while logic provides the rigour and explanation capability to the systems, facilitating the interaction with the outside world. Although it is left as future work to determine whether the structure of one of the proposed approaches is more amenable to learning than the other, we hope to have contributed to the development of the area by approaching it from the perspective of symbolic and sub-symbolic integration.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.1 (2003) 17-21 [Access article in PDF] Self-Injury:Symbolic Sacrifice/Self-Assertion Renders Clinicians Helpless Christa Krüger Keywords feminism, iconic communication, moral conflict, oppression, psychiatrist/psychologist roles, societal norms. POTTER'S PAPER CONSIDERS self-injury in women diagnosed with borderline person ality disorder (BPD) to be a form of body modification where the body is used to communicate meaning. She touches on symbolism as a possible explanatory theory for this (...) sort of self-injury. She also refers to the culture of body commodification as underlying self-injury. She then argues that clinicians have a duty to give uptake to the patient's own interpretations about the meaning of the self-injury. Giving uptake is a virtuous approach for ethical interactions with people diagnosed with BPD who self-injure, and it aims to preserve the communicator's integrity, along with other benefits. Potter offers five maxims for giving uptake properly. However, I shall argue that giving uptake can be very difficult for clinicians, and that an appreciation of this difficulty depends on an expansion and linkage of some of the theories that she touched on. Self-injury is revisited experimentally as a double-edged sword of symbolic sacrifice and iconic-symbolic self-assertion. This revisiting aims to illustrate how clinicians might be caught in a double bind, where giving uptake properly might be very difficult if not more or less doomed to fail.Potter's paper starts by situating self-injury in a broader discourse of body modifications. In this discourse the body is being used as a text, a tool to communicate meaning. The meaning that is communicated might be difficult or impossible to articulate otherwise (by using words, for example). The meaning of the communication is embedded in a context of social, cultural, religious, political, and other norms. Potter explores possible interpretations of the meaning of self-injury in women with BPD, including an interpretation of self-injury as symbolic sacrifice. She suggests that a cultural understanding/nonunderstanding of the meaning of a particular instance of self-injury is an important determinant of whether such self-injury is considered pathological/nonpathological. She then shifts the focus to the present-day culture in which women's bodies are commodified and objectified, and where women become alienated from their bodies. Self-injury might then be interpreted as an attempt to re-own one's body as a part of oneself. This re-owning is a socially transgressive act that violates repressive norms for the bodies of women. [End Page 17]Notwithstanding these possible significations of self-injury, Potter then argues that clinicians have a duty to give uptake to the patient's own interpretations, instead of jumping to conclusions (my oversimplification) about the meaning of the self-injury. Giving uptake, then, constitutes a framework for ethical interactions with people diagnosed with BPD who self-injure, and it aims to preserve the communicator's integrity. Potter offers five maxims for giving uptake properly.At the risk of losing their essence, I translate the five maxims for practicing psychiatrists as involving the following: critical self-reflection about one's own conceptual framework and cultural context; being receptive to the patient's conceptual framework and cultural context; giving the patient the benefit of the doubt; being open to the emergence of new meanings of self-injury; and keeping a range of possible interpretative options open, rather than insisting on having the final word. We should try to understand what the world looks like from the patient's position. All of this requires some moral effort.Potter describes a number of benefits that result from giving uptake. Giving uptake is a crucial corrective to the human tendencies of becoming overly committed to prevailing societal norms and conceptual schemes (stuck in our ways), of imposing our views on others, and of silencing or distorting the communications of our patients. Giving uptake allows clinicians to be dialogically responsive and to treat patients with respect and dignity. Giving uptake fosters trust in a therapeutic relationship where clinicians do not exploit their patients' vulnerabilities. Giving... (shrink)

This paper describes two collaborative projects that illustrate the value of learning symbolic logic and provide students (and instructors) a break from the routine work of learning new symbols or proof techniques. The first project has students work together to reconstruct the argument in Peter Singer’s “Famine, Affluence, and Morality”. This project has the benefit of showing students that what they are reading in college has an underlying logical structure and that their knowledge of conditionals, conjunctions, etc. functions in (...) real, argumentative discourse. The second project introduces students to four key concepts: self-reference, paradox, and metatheory, and then exposes them to key metatheoretic concepts (consistency and completeness) and to Gödel’s incompleteness proof.

Scientific interest in genomics in Africa is on the rise with a number of funding initiatives aimed specifically at supporting research in this area. Genomics research on material of African origin raises a number of important ethical issues. A prominent concern relates to sample export, which is increasingly seen by researchers and ethics committees across the continent as being problematic. The concept of genomic sovereignty proposes that unique patterns of genomic variation can be found in human populations, and that these (...) are commercially, scientifically or symbolically valuable and in need of protection against exploitation. Although it is appealing as a response to increasing concerns regarding sample export, there are a number of important conceptual problems relating to the term. It is not clear, for instance, whether it is appropriate that ownership over human genomic samples should rest with national governments. Furthermore, ethnic groups in Africa are frequently spread across multiple nation states, and protection offered in one state may not prevent researchers from accessing the same group elsewhere. Lastly, scientific evidence suggests that the assumption that genomic data is unique for population groups is false. Although the frequency with which particular variants are found can differ between groups, such genes or variants per se are not unique to any population group. In this paper, the authors describe these concerns in detail and argue that the concept of genomic sovereignty alone may not be adequate to protect the genetic resources of people of African descent.

Jason Brennan and Peter Jaworski reject expressive objections to markets on the grounds that market symbolism is culturally contingent, and contingent cultural symbols are less important than the benefits markets offer. I grant and, but I deny that these points suffice as grounds to dismiss expressive critiques of markets. For many plausible expressive critiques of markets are not symbolic critiques at all. Rather, they are critiques grounded in the idea that some market transactions embody morally inappropriate normative stances (...) toward the goods or services on offer. (shrink)

Concretization is a concept that has different meanings in different psychological theories and varying manifestations in different psychotherapies. In psychodrama, much of the available information on concretization draws on J. L. Moreno’s initial conceptualization, descriptive case studies, and interpretations in the various approaches. However, concretization has not been empirically studied as a concept or as a therapeutic mechanism of change. Therefore, the purpose of this qualitative study was to generate an empirically based conceptualization and operationalization of concretization as well as (...) to identify its clinical benefits in psychodrama. To this end, semistructured in-depth interviews were conducted with seven experienced psychodrama therapists. Using a grounded theory approach for the data analysis, the model that emerged consists of three pathways toward concretization: realistic concretization, symbolic concretization, and integrated concretization. The findings suggest a sequential multistep operation that can be linear or nonlinear, depending on the protagonist’s need. The findings also underscore four benefits of concretization as a mechanism of change in psychodrama: reducing the ambiguity of the problem, externalizing the protagonist’s problem, enhancing the therapist-protagonist therapeutic bond, and bypassing the protagonist’s defense mechanisms. The model is discussed in light of the findings and the literature, and future directions are suggested. (shrink)

This article examines two disputes within sex and gender movements, using them to think through inclusion/exclusion processes, the place of such explosions in the construction of collective identity, and the gendered nature of social movements. Literatures on collective identity emphasize the ways boundary negotiation reinforces the solidarity necessary for collective action and note benefits of solid boundaries, yet downplay the role of internal conflict in the making of collective identities. The cases examined here both involved the explicit expulsion of (...) some “members”: the North American Man/boy Love Association from the International Lesbian and Gay Association, and transsexuals from the Michigan Womyn's Music Festival. An incongruence between practical participation and symbolic exclusion suggests that internal movement debates are best understood as public communications, depending heavily on the communicative environment. Finally, these stories raise questions about the gendered nature of collective identity construction in social movements more generally. (shrink)

This title is playful, of course. It is designed merely to attract curiosity and attention … It dates back to a childhood game of which I have forgotten both rules and stakes. An imaginary sovereign was roused from his indifference and responded with an approximate repetition of Marie-Antoinette's suggestion that if the people were hungry, food should be thrown to them. I took such caricatures of kings as anti-models, replacing bread with symbols. Now we are all too disturbed, individually and (...) collectively, by the economic discomfort which is a generalized hunger and, in too many parts of the world and - not only in the third world - by actual famines, not to be aware, on a daily basis, of the responsibility it is to cultivate and transmit to others substance which is purely symbolic. Certain statistics, which now form part of our daily life, are capable of discrediting definitively the ivory tower which our universities are accused of representing, or of having represented in the past. In my own country, Canada, one child in five lives in poverty. The economic worth of the poorest forty-eight countries in the world is equal to the combined wealth of the ten richest individuals. There were twenty million refugees in 1997. One billion two hundred million human beings are short of fresh water this year, etc. This type of figure is, sadly, all too familiar. And it is a case of preaching to the converted to assert the extent to which culture, education and all their constituent disciplines are nourishment of a different order to physical food, because intellectual work is genuine work, providing a living for those who work at it professionally, and above all also those who benefit from its immediate and continuing fruits - i.e. ideally, the whole of society, and in all countries. In this respect - and this is implicit, but through depending habitually on what is implicit nothing is ever sufficiently explicit - it is generally acknowledged (thanks to UNESCO in particular) to what extent the development of economic resources is linked with the advancement and communication of knowledge, on a scale which is regional as well as national, within cities, rural communities, families.

Use of symbols, the key to the biosemiotics field as to many others, required bigger brains which implied a promissory note for greater energy consumption; symbols are obviously expensive. A score years before the current estimate of 18–20% for the human brain’s metabolic demand on the organism, it was known that neural tissue is metabolically dear. This paper first discusses two evolutionary responses to this demand, on both of which there is some consensus. The first, assigning care of altricial infants (...) with burgeoning brains (and in human infants the metabolic demand peaks at 65% of the total) to “allomothers” is not unique to humans. The second, using relatively small neurons as primates do, risks misfires past a certain minimal value. Moreover, in apparent paradox, there is an increasing consensus that large “Von Economo” neurons are critical for communication. This paper’s main contribution is the discussion of two further evolutionary tricks. The first is the use of self-similarity in the cortex, both in structure and process, to allow the cortex readily—and in energetic terms, parsimoniously—to shift between states in a high-dimensional space. This leads to discussion of the kind of formalism appropriate to model these shifts, a formalism which—it is tentatively suggested—may do double duty for the modeling of symbolic thought. The second trick is the superimposition on the background “white noise” of neural firing of EEG-detected waves like gamma. The paper describes a method, using the Hilbert transform, of calculating the dips in energy consumption as the brain is transitioned by gamma waves. It is hypothesized that consciousness may be a spandrel, the incidental result of a neurodynamic imperative that the brain enter a maximally sensitive (in sensory terms) “zero power” state a few times a second. If that is the case, then there are obvious benefits for health in meditation, which can be viewed as a state of consciousness extended over time by limiting afferent stimuli. (shrink)

When Communism collapsed in Central and Eastern Europe women seemed to lose the control they had gained over their reproductive lives. Abortion rights became more limited as did access to childcare and maternity benefits. The authors argue that this picture conceals two key points. First, the effects of both Communism and post-Communism for women's reproductive lives need to be understood as byproducts of state initiatives geared towards the fulfilment of quite different political goals – and not attempts to intervene (...) in women's health and well-being per se. Second, these effects are very varied and cannot be attributed to a single cause. ‘Central and Eastern Europe’ comprises a whole range of political, ethnic and religious groupings, the result being that women's reproductive lives have been shaped within a diversity of political processes. Some women have faced pressures from the state to reproduce, some have lost the conditions necessary for them to continue paid work after childbirth, others have lost abortion rights. To understand these very different outcomes of post-Communism, this article looks beyond women's issues per se to unravel their role as symbolic resources which have been drawn upon in power struggles taking place in political arenas which exclude the majority of women. This argument is elaborated through empirical evidence from Poland, Serbia and East Germany. (shrink)

Barsalou's theory of perceptual symbol systems is considered from a metacognitive perspective. Two examples are discussed in terms of the proposed perceptual symbol theory. First, recent results in research on feeling-of-knowing judgement are used to argue for a representation of familiarity with input cues. This representation should support implicit memory. Second, the ability of maintaining a theory of other people's beliefs (theory of mind) is considered and it is suggested that a purely simulation-based view is insufficient to explain the available (...) evidence. Both examples characterize areas where Barsalou's theory would benefit from additional detail. (shrink)

Music is an artistic cultural innovation, and therefore it may be considered as intuitive thought expressed in symbols, which can efficiently convey multiple meanings in learning, thinking, and transmission, selected for and passed on through cultural evolution. The symbolic system has personal adaptive benefits besides social ones, which should not be overlooked even if music may tend more to the latter.

Although several articles have investigated ethical product attributes, earlier research has not empirically examined different benefits offered by ethical attributes. This study demonstrates that ethical attributes have functional benefits as well as symbolic benefits. More importantly, when the ethical attribute benefit is congruent with the product category benefit, ethical attributes improve product evaluations. In addition, products with a higher degree of physical contact with consumers are affected more positively by benefit congruity of ethical attributes. For products (...) with lower degree of physical contact, benefit congruity of ethical attributes still has a positive impact, but not for consumers who have strong price–quality beliefs. (shrink)

This paper explores how English language has gradually become a linguistic form of cultural capital in China’s zigzag journey to modernization. It situates English’s status in flux in historical context, with an analysis at both the international and intra-national level. It showcases the necessity to embed cultural capital within Bourdieu’s full framework, and evidences the arbitrary nature of this form of cultural capital for its intimate tie to power and politics. By revealing how English has been officially consecrated as a (...) global lingua franca and then socially recognized for material and symbolic benefits, this paper implicitly problematizes the officially validated cultural hierarchy, argues that the value of a cultural capital is context-dependent, politically and socially constructed, inseparable from the field where it is produced. The present-day English manifests its symbolic power in classification and social stratification, entrenching the already entrenched inequality within and without the national state. (shrink)

In 1998, the Labour government introduced legislation broadening British sentencing powers in relation to crimes aggravated by the offender's hostility towards the victim's actual or perceived race, religion, sexual orientation or disability. Gender is a notable omission from this list. Through a survey of eighty-eight stakeholders working in the violence against women (VAW) sector, this paper explores both the potential benefits and possible disadvantages of adding a gender-based category concerned with VAW to British hate crime legislation. The majority of (...) participants believed that a hate crime approach would offer significant benefits, especially in terms of the symbolic power of the law to send a message to society that VAW is unacceptable. However, most also recognised that the addition of a VAW category to current legislation would involve major practical and conceptual difficulties, not least those resulting from problematic assumptions about the nature of hate crimes versus VAW, and a general unwillingness on the part of policy-makers to address the socio-cultural inequalities that underpin VAW. Overall, the fact that the majority of participants favoured inclusion, on the basis that the possible symbolic benefits were likely to outweigh the potential practical disadvantages, is significant: it speaks to the power of hate crime legislation to challenge many forms of inequality and discrimination still endemic in British society.

Undergraduate students with no prior classroom instruction in mathematical logic will benefit from this evenhanded multipart text by one of the centuries greatest authorities on the subject. Part I offers an elementary but thorough overview of mathematical logic of first order. The treatment does not stop with a single method of formulating logic; students receive instruction in a variety of techniques, first learning model theory (truth tables), then Hilbert-type proof theory, and proof theory handled through derived rules. Part II supplements (...) the material covered in Part I and introduces some of the newer ideas and the more profound results of logical research in the twentieth century. Subsequent chapters introduce the study of formal number theory, with surveys of the famous incompleteness and undecidability results of Godel, Church, Turing, and others. The emphasis in the final chapter reverts to logic, with examinations of Godel's completeness theorem, Gentzen's theorem, Skolem's paradox and nonstandard models of arithmetic, and other theorems.

The list of saints dragonslayers is long in Western tradition: from archangel Michael, Saint George, Saint Marcel up to captain Nemo from the famous Jules Verne’s novel. It is quite different in East Asia and especially in China, where the dragon benefits from an extremely positive valuation. What are the causes of such a symbolic reversal? This is what we are trying to elucidate in this paper. The dragon, so laden with malignity in the West and requiring a (...) hero to fight it and to restore, against multiple perversity, the solidity of the concept of being, is an auspicious image in the Chinese world that benefits from the riches of multiplicity: assimilated to the “Son of Heaven”, emperor of all under heaven, located in the center of the changing world, he ensures the correct order of political, geographic, calendar, or anthropological pluralities. Two world views stand face to face: one that saves being by slaying the dragon, the other which recognizes the value of changes and transformations. (shrink)

The fundamental assumptions in Dijkstra''s influential article on computing science teaching are challenged. Dijkstra''s paper presents the radical novelties of computing, and the consequent problems that we must tackle through a formal, logic-based approach to program derivation. Dijkstra''s main premise is that the algorithmic programming paradigm is the only one, in fact, the only possible one. It is argued that there is at least one other, the network-programming paradigm, which itself is a radical novelty with respect to the implementation of (...) problems on computers. And, as one might expect of a radical alternative, it shows much of the conventional wisdom concerning computing science, which Dijkstra variously attacks and dispenses, to be special pleading; not universals of computing at all. Finally, we explore what is known of this new paradigm in order to see what light it sheds on the fundamental problems that computing really does present to us. Not surprisingly, some become less problematic, some disappear altogether and others take their place, but, in general, it must be of benefit to modern computer technology to gain a wider perspective on the possibilities instead of seeing everything through the traditional tunnel of programming as formula derivation, and computers as the requisite, special type of symbol manipulation device.

The paper analyses the use of the Romani language in the Slovak educational system. It focuses on the informal use of Romani in schools, as about 10% of all pupils speak Romani as their mother tongue but there are no schools that use Romani as the language of instruction. The theoretical framework draws mainly on the work of P. Bourdieu and S. May on the symbolic power of language. The empirical chapter is based on qualitative data collected at ten (...) primary schools in different parts of Slovakia, as well as interviews with decision makers and experts. On the basis of the empirical research, three questions are posed. (1) Is Romani used in schools and if so how? (2) What attitudes do school staff have on the use of Romani? (3) Is the theory of Stephen May applicable to Slovakia and is Romani perceived to have merely sentimental value while Slovak is considered to have instrumental value? The article concludes that the perceived value of Romani in Slovakia is very low. From the point of view of school staff, it has no instrumental value and is perceived as a barrier rather than a benefit. (shrink)

Connectionist attention to variables has been too restricted in two ways. First, it has not exploited certain ways of doing without variables in the symbolic arena. One variable-avoidance method, that of logical combinators, is particularly well established there. Secondly, the attention has been largely restricted to variables in long-term rules embodied in connection weight patterns. However, short-lived bodies of information, such as sentence interpretations or inference products, may involve quantification. Therefore short-lived activation patterns may need to achieve the effect (...) of variables. The paper is mainly a theoretical analysis of some benefits and drawbacks of using logical combinators to avoid variables in short-lived connectionist encodings without loss of expressive power. The paper also includes a brief survey of some possible methods for avoiding variables other than by using combinators. (shrink)

Niche construction theory highlights the active role of organisms in modifying their environment. A subset of these modifications is the developmental niche, which concerns ecological, epistemic, social and symbolic legacies inherited by organisms as resources that scaffold their developmental processes. Since in this theory development is a situated process that takes place in a culturally structured environment, we may reasonably ask if implicit cultural biases may, in some cases, be responsible for maladaptive developmental niches. In this paper we wish (...) to argue for an affirmative answer. In order to do so, we first propose to conceptualize implicit bias as embodied perceptual habits, and then proceed to show that these habits are at least partially responsible for maladaptive developmental niches of children with Down syndrome and autism. With this framework we thus hope to bring together two fields of research that haven’t been explicitly connected: implicit bias and niche construction theory. Linking these two theories may bring benefits both to implicit bias researchers, who can extend this concept to characterize other sets of processes as biased, as well as to niche construction theorists, who will have a useful theoretical tool to diagnose maladaptive features of niches brought about by sociocultural biases.

As Mircea Eliade’s translator and biographer Mac Linscott Rickett states, Eliade involved the whole discipline of the history of religions in the quest for meaning. The paper examines Eliade’s approach of religious documents, with benefits and shortcomings as appraised by some of his American critics, and looks closely at the Eliadean creative hermeneutics and the ambitious mission he envisaged for the discipline he has founded in the United States.

Mathematical game theory has been embraced by a variety of scholars: social scientists, biologists, linguists, and now, increasingly, logicians. This volume illustrates the recent advances of game theory in the field. Logicians benefit from things like game theory's ability to explain informational independence between connectives; meanwhile, game theorists have even begun to benefit from logical epistemic analyses of game states. In concert with such pioneering work, this volume also present surprising developments in classical fields, including first-order logic and set theory.
