In this paper we propose a formal theory of metaphors called Constrained Semantic Transference [CST]. We start from the assumptions that metaphors are characterized by the description of one domain, called the target domain, in terms of another domain, called the source domain; and that a metaphor works by transferring a set of structural relationships from the source domain to the target domain coherently.Starting from these assumptions, we formally define the concept of T-MAPs which are partial coherent mappings from the (...) source domain to the target domain. We also define two operators, called Augmentation and Positing Structure that extend a given T-MAP by adding new structure to the target domain. (shrink)

Both mainstream and art comics often use various flourishes surrounding characters’ heads. These so-called “pictorial runes” help convey the emotional states of the characters. In this paper, using panels from Western and Indian comic albums as well as neutral emoticons and basic shapes in different colors, we focus on the following two issues: whether runes increase the awareness in comics readers about the emotional state of the character; and whether a correspondence can be found between the types of runes and (...) specific emotions. Our results show that runes help communicate emotion. Although no one-to-one correspondence was found between the tested runes and specific emotions, it was found that droplets and spikes indicate generic emotions, spirals indicate negative emotions, and twirls indicate confusion and dizziness.

In this paper we start from the assumption that in a metaphor, or an analogy, some terms belonging to one domain (source domain) are used to refer to objects other than their conventional referents belonging to a possibly different domain (target domain). We describe a formalism, which is based on the First Order Predicate Calculus, for representing the knowledge structure associated with a domain and then develop a theory of Constrained Semantic Transference [CST] which allows the terms and the structural (...) relationships of the source domain to be transferred coherently across to the target domain. We show how metaphors and analogies can be characterized in CST in such a way that many of their cognitive properties con be explained.We then propose a theory of Approximate Semantic Transference [AST] which is a computational version of CST and is derived from it by replacing the coherency requirement with approximate coherency. We show how AST can be used as a basis for designing models of cognitive processes involved in comprehending metaphors and analogies. (shrink)

This paper begins with a rigorous critique of David Stove''s recent bookThe Rationality of Induction. In it, Stove produced four different proofs to refute Hume''s sceptical thesis about induction. I show that Stove''s attempts to vindicate induction are unsuccessful. Three of his proofs refute theses that are not the sceptical thesis about induction at all. Stove''s fourth proof, which uses the sampling principle to justify one particular inductive inference, makes crucial use of an unstated assumption regarding randomness. Once this assumption (...) is made explicit, Hume''s thesis once more survives.The refutation of Stove''s fourth proof leads to some observations which relate Goodman''s grue paradox with randomness of a sample. I formulate a generalized version of Goodman''s grue paradox, and argue that whenever a sample, no matter how large, is drawn from a predetermined smaller interval of a population that is distributed over a larger interval, any conclusion drawn about the characteristics of the population based on the observed characteristics of the sample is fatally vulnerable to the generalized grue paradox.

The present study examines the relationship between pictorial similes and hybrid pictorial metaphors. The results suggest that hybrid pictorial metaphors are perceived more strongly than pictorial similes when they are presented on their own and in corrective convention but not when they are verbalized. We argue that hybrid pictorial metaphors have transformational effects as the fusion of two concepts allow the reader to see one thing in terms of another. Juxtaposition in a pictorial simile merely suggests a search for similarity, (...) which is not explicit. Results also showed that verbalized metaphor (X is Y) or the simile (X is like Y) forms are often used to convey a similar meaning and strength for pictorial simile and pictorial metaphor. However, in corrective scenarios participants are forced to reassess visual features: in this situation, pictorial metaphors are considered more strongly than pictorial similes even when they are verbalized.

A metaphor can often create novel features in an object or a situation. This phenomenon has been particularly hard to account for using amodal symbol systems: although highlighting and downplaying can explain the shift of focus, it cannot explain how entirely new features can come about. We suggest here that the dynamism of perceptual symbol systems, particularly the notion of simulator, provides an elegant account of the creativity of metaphor. The elegance lies in the idea that the creation of new (...) features by a metaphor proceeds in the same way as the creation of regular features in a perceptual symbol. (shrink)

Focusing on the mirror system and imitation, I examine the role of metaphor and projection in evolutionary neurolinguistics. I suggest that the key to language evolution in hominid might be an ability to project one's thoughts and feelings onto another agent or object, to see and feel things from another perspective, and to be able to empathize with another agent.

Considerations from an interaction-based approach to the evolution of language and the role of word-sentences therein show that the object-attribute ontology is arrived at a much later stage. Therefore, Hurford's arguments, by focusing on the predicate-argument structure, seem to miss out on most of the interesting aspects of the early stages in language evolution.

The role of figurative languages such as metaphor and metonymy in creativity has been studied in cognitive linguistics. These methods can also be applied to analyze non-linguistic data such as pictures and gestures. In this paper we analyze fashion design by focusing on visual metaphor and metonymy. The nature of creativity in fashion design is not fully studied from a cognitive perspective compared to other related fields such as art. We especially focus on the aspect of fashion design as a (...) communication tool between the designer and the audience to convey designer’s image of human. Photos from two fashion shows are analyzed. We carried out an experiment to compare how human images in two shows are interpreted by those who are familiar with fashion and those who are not. We got three results: (1) As far as figurative (metaphorical and metonymic) interpretations of human image are concerned, two groups with different familiarity to fashion have significantly different patterns of responses to two shows. (2) For non-figurative interpretations (such as physical or personal attributes), no significant difference in the pattern of response to the show was observed between two groups. The participants as a whole, however, responded to the two shows differently. (3) In addition for non-figurative interpretation, fashion experts found significantly more attributes in human images than the others. The results show that the analysis of figurative interpreations is effective in seeing how the familiarity to fashion affects the mode of seeing fashion shows. (shrink)

Community engagement is increasingly recognized as a critical element of medical research, recommended by ethicists, required by research funders and advocated in ethics guidelines. The benefits of community engagement are often stressed in instrumental terms, particularly with regard to promoting recruitment and retention in studies. Less emphasis has been placed on the value of community engagement with regard to ethical good practice, with goals often implied rather than clearly articulated. This article outlines explicitly how community engagement can contribute to ethical (...) global health research by complementing existing established requirements such as informed consent and independent ethics review. The overarching and interlinked areas are respecting individuals, communities and stakeholders; building trust and social relationships; determining appropriate benefits; minimizing risks, burdens and exploitation; supporting the consent process; understanding vulnerabilities and researcher obligations; gaining permissions, approvals and building legitimacy and achieving recruitment and retention targets.

BackgroundHealthcare ethics is neglected in clinical practice in LMICs such as Nepal. The main objective of this study was to assess the current status of knowledge, attitude and practice of healthcare ethics among resident doctors and ward nurses in a tertiary teaching hospital in Nepal.MethodsThis was a cross sectional study conducted among resident doctors and ward nurses in the largest tertiary care teaching hospital of Nepal during January- February 2016 with a self-administered questionnaire. A Cramer’s V value was assessed to (...) ascertain the strength of the differences in the variables between doctors and nurses. Association of variables were determined by Chi square and statistical significance was considered if p value was less than 0.05.ResultsOur study demonstrated that a significant proportion of the doctors and nurses were unaware of major documents of healthcare ethics: Hippocratic Oath, Nuremberg code and Helsinki Declaration. A high percentage of respondents said that their major source of information on healthcare ethics were lectures, books, and journals. Attitude of doctors and nurses were significantly different in 9 out of 22 questions pertaining to different aspects of healthcare ethics. More nurses had agreement than doctors on the tested statements pertaining to different aspects of healthcare ethics except for need of integration of medical ethics in ungraduate curricula,paternalistic attitude of doctor was disagreed more by doctors. Notably, only few doctors stood in support of physician-assisted dying.ConclusionsSignificant proportion of doctors and nurses were unaware of three major documents on healthcare ethics which are the core principles in clinical practice. Provided that a high percentage of respondents had motivation for learning medical ethics and asked for inclusion of medical ethics in the curriculum, it is imperative to avail information on medical ethics through subscription of journals and books on ethics in medical libraries in addition to lectures and training at workplace on medical ethics which can significantly improve the current paucity of knowledge on medical ethics.

Cognitive dysfunction in Alzheimer’s disease is caused by disturbances in neuronal circuits of the brain underpinned by synapse loss, neuronal dysfunction and neuronal death. Amyloid beta and tau protein cause these pathological changes and enhance neuroinflammation, which in turn modifies disease progression and severity. Vagal nerve stimulation, via activation of the locus coeruleus, results in the release of catecholamines in the hippocampus and neocortex, which can enhance synaptic plasticity and reduce inflammatory signalling. Vagal nerve stimulation has shown promise to enhance (...) cognitive ability in animal models. Research in rodents has shown that VNS can have positive effects on basal synaptic function and synaptic plasticity, tune inflammatory signalling, and limit the accumulation of amyloid plaques. Research in humans with invasive and non-invasive VNS devices has shown promise for the modulation of cognition. However, the direct stimulation of the vagus nerve afforded with the invasive procedure carries surgical risks. In contrast, non-invasive VNS has the potential to be a broadly available therapy to manage cognitive symptoms in early AD, however, the magnitude and specificity of its effects remains to be elucidated, and the non-inferiority of the effects of non-invasive VNS as compared with invasive VNS still needs to be established. Ongoing clinical trials with healthy individuals and patients with early AD will provide valuable information to clarify the potential benefits of non-invasive VNS in cognition and AD. Whether invasive or non-invasive VNS can produce a significant improvement on memory function and whether its effects can modify the progression of AD will require further investigation. (shrink)

Metaphor is one of the most frequently evoked but at the same time most poorly understood concepts in philosophy and literary theory. In recent years, several interesting approaches to metaphor have been presented or outlined. In this volume, authors of some of the most important new approaches re-present their views or illustrate them by means of applications, thus allowing the reader to survey some of the prominent ongoing developments in this field. These authors include Robert Fogelin, Susan Haack, Jaakko Hintikka (...) (with Gabriel Sandu), Bipin Indurkhya and Eva Kittay (with Eric Steinhart). Their stance is in the main constructive rather than critical; but frequent comparisons of different views further facilitate the reader's overview. In the other contributions, metaphor is related to the problems of visual representation (Noël Carroll), to the open class test (Avishai Margalit and Naomi Goldblum) as well as to Wittgenstein's idea of `a way of life' (E.M. Zemach). (shrink)

Empirical analyses have provided some important constraints for computational theories of metaphor. Three such constraints relate to (1) the similar processing time for literal and metaphorical language, (2) the time‐limited processing of many metaphors, and (3) the dissociation of metaphor comprehension and appreciation. Indurkhya's (1986, 1987) model is discussed with respect to these issues.
