Yes / The goal of this study was to investigate the reference frames used in perceptual encoding and storage of visual motion information. In our experiments, observers viewed multiple moving objects and reported the direction of motion of a randomly selected item. Using a vector-decomposition technique, we computed performance during smooth pursuit with respect to a spatiotopic (nonretinotopic) and to a retinotopic component and compared them with performance during fixation, which served as the baseline. For the stimulus encoding stage, which precedes memory, we found that the reference frame depends on the stimulus set size. For a single moving target, the spatiotopic reference frame had the most significant contribution with some additional contribution from the retinotopic reference frame. When the number of items increased (Set Sizes 3 to 7), the spatiotopic reference frame was able to account for the performance. Finally, when the number of items became larger than 7, the distinction between reference frames vanished. We interpret this finding as a switch to a more abstract nonmetric encoding of motion direction. We found that the retinotopic reference frame was not used in memory. Taken together with other studies, our results suggest that, whereas a retinotopic reference frame may be employed for controlling eye movements, perception and memory use primarily nonretinotopic reference frames. Furthermore, the use of nonretinotopic reference frames appears to be capacity limited. In the case of complex stimuli, the visual system may use perceptual grouping in order to simplify the complexity of stimuli or resort to a nonmetric abstract coding of motion information.

Summary: This thesis builds on current research about image schema PATH in Czech language. After a theoretical introduction of the cognitive-linguistic theory of conceptual, or image schemas and about iconic and iconic-metaphorical (double) mapping of sign language existing theoretical and methodological knowledge is compared with language material that captures expressions schema PATH in the Czech sign language. For these purposes a corpus of signs of Czech sign language that make use of the schema of PATH was acquired. Analyzed signs are categorized by target areas (semantic circuits) and also according to the criteria of phonological structure. Key words: cognitive linguistics, Czech sign language, metaphor, iconic mapping, iconic-metaphoric (double) mapping, image schema, image schema PATH

This thesis is focused on the conceptualisation of emotions in Czech Sign Language with the emphasis on the linguistic conceptualisation of anger. At the beginning the author reveals basic theoretical issues of the cognitive linguistics of spoken and sign linguistics. Afterwards she presents some general facts about metaphor and metonymy in spoken and sign languages - with the main focus on the metaphorical-metonymic conceptualisation of anger - and shows metaphors and metonymies of anger in the English, Polish and Czech language. The core of the thesis consists of the linguistic research of anger in Czech Sign Language. The author identifies basic metaphors and metonymies of the concept of ANGER in Czech Sign Language within the empirically gained linguistic material. The gained data from all four languages are compared and presented in a table at the end of this paper. Key words: cognitive linguistics, emotions, conceptualisation of emotions, the concept of ANGER, Czech Sign Language, metaphor, metonymy, metaphorical mapping, iconic mapping, iconic-metaphorical mapping.

O presente estudo tem por objetivo compreender o consumo de marcas icônicas globais por consumidores de alto poder econômico e baixo capital cultural, em um contexto de país em desenvolvimento. O consumo de marcas icônicas globais auxilia os indivíduos a construir e a sinalizar sua identidade social. O uso e a forma de apropriação de marcas icônicas globais, no contexto brasileiro, atuam como um mecanismo empregado para demarcar uma posição favorável dentro da hierarquia social e gerar distinção entre indivíduos e grupos sociais. Especificamente, buscou-se analisar e compreender os discursos empregados pelas consumidoras para significar, enquadrar, justificar e legitimar o consumo dessas marcas. A pesquisa tem caráter qualitativo e descritivo e foi realizada por meio de entrevistas em profundidade e de observação com vinte e uma mulheres de alto poder econômico e baixo capital cultural. Como resultados desta pesquisa, com base nas distintas narrativas identificadas, categorizou-se os discursos das consumidoras de marcas icônicas globais em quatro grupos. As utilitárias verbalizam que consomem pelos benefícios funcionais, não admitindo consumir o simbolismo. As racionais revelam que alcançam o prazer individual, mas descartam o consumo exibicionista. As ascendentes consomem como fonte de prazer individual e pelo simbolismo do prestígio alcançado por conta da ascensão profissional e social. Por fim, as exibicionistas consomem prioritariamente o valor simbólico do prestígio a fim de sinalizar a diferenciação social perante os demais e pares. Além disso, verificou-se que as consumidoras são fortemente impactadas pela cultura global do consumo, emulando o consumo de países desenvolvidos e, similarmente, o da elite brasileira. Esta pesquisa adiciona nuances à análise do consumo de tais marcas dentro do estrato de alto poder econômico e baixo capital cultural, superando a análise binária de alto e baixo capital cultural de estudos anteriores, identificando e classificando quatro diferentes tipos de narrativas quanto a práticas e significados vinculados ao consumo dessas marcas. / The present study aims to understand the consumption of global iconic brands by consumers with high economic power and low cultural capital, in a developing country context.

This thesis focuses on the use of smart materials in microrobotic applications. The development of materials with the capabilities to mechanically respond to electrical stimuli or, at the same time, to electrically respond to mechanical stimuli, has entailed the microrobotics rapid evolution. Along this thesis the use of three smart materials families in the filed of microrobotics is studied. The materials used are the piezoelectric ceramics, the piezoelectric polymers and the ionic polymers metal composites IPMC. The similitude in the way they respond to external stimuli has motivated this study. The three materials respond with an induced mechanical strain under the application of an electric field and respond with an induced electrical charge variation when a mechanical pressure is applied. Although these materials respond similarly, their application in microrobotic systems entails different problems. In this thesis their use in different applications is studied and the problems enclosed with their use are treated. First of all in this thesis the use of piezoelectric polymers and ionic polymers as materials for motion control of microrobots is studied. Their flexibility opens the door to new applications for microrobot systems as is the case of biomimetics. The first application regards the use of piezoelectric polymers in insect-like mm3 microrobot. The microrobot is composed with three legs and one antenna or tool for object collision based on piezoelectric polymers. The object collision tool is used as a sensor for motion control to avoid collisions with other objects. The work presented consists on the development of theoretical models to predict the motion of he leg and the tool of the microrobot. The second application regards the development of a control system for controlling the motion of an ionic polymer IPMC underwater. It is difficult to obtain physical models that describe the motion of these materials, thus it is important to design control strategy to work with IPMCs. Furthermore in this thesis, the problem of manufacturing electrodes for IPMC is also treated.In the second part of the thesis the use of piezoelectric ceramics to harvest power from mechanical vibrations is studied. Piezoelectric ceramics have higher energy densities compared with other methods for power harvesting from vibrations. In comparison with the piezoelectric polymers, the piezoelectric ceramics produce voltages and current levels more acceptable. From the study performed in this thesis the conditions for a maximum power generation are obtained and an optimum electronic circuit for energy storage and management is designed. At the end of the thesis the capabilities to harvest power using ionic polymers are studied.KEY WORDS: Smart Materials, Microrobotic, Harvesting, Motion Control, Fonic Polimer, FPMC Piezoelectric, Modelling / Aquesta tesis es centra en l'ús de materials "smart" o intel·ligents en aplicacions de microrobòtica.

The goal I have pursued in writing this dissertation has been to provide the most complete account that I could manage of the various aspects of language that can be labelled metalinguistic, both in the language-system and in discourse. On a rough characterisation, metalanguage is language about language. Since I understand language both as a ‘potential’ (the language-system) and as its actualisation (language as discourse), there are theoretically four situations that can be subsumed under the term ‘metalanguage’: 1. there are lexical items (units in the system) that denote aspects of the system (preposition, noun, conjugation, plural, etc.); 2. there are items that denote elements of discourse (words and phrases like the aforementioned, the latter, etc.). At the same time, there are 3. utterances about the system (e.g. ‘Boston’ is a noun), and 4. utterances about discourse (i.e. about other utterances or parts of utterances, e.g. The old cow said teddible instead of terrible). In both 3 and 4, we have words that reflexively mention linguistic sequences. Following Rey-Debove, I have chosen to call these ‘autonyms’.Note also that discourse about language can be combined with discourse about extralinguistic reality. An utterance about a situation in the world can secondarily say something, for example, about language use; such is the case in The U.S. advocates ‘military action’, as newspapermen call it now, where a comment about a euphemism is appended to a statement about ‘the world’.All in all, this amounts to a fairly large body of data that is varied in kind. My goal has been to bring some order to this variegated set, to highlight in what respects its elements are similar and dissimilar. Thus, I have sought to sort out a number of issues that had not, as far as I could judge, been treated satisfactorily on previous occasions, and to make my descriptions compatible with the theory that was gradually taking shape. In particular, I have underlined the strong connections between the system-level aspects of metalanguage and its discourse manifestations, and I have been led to suggest that the latter ‘leak into’ the system. Besides, I have tried to give a more thorough account of certain properties of metalinguistic discourse, notably the recursiveness of mention or quotation, and its referential diversity. When I felt that I had come to an adequate account of metalinguistic discourse, I have attempted to supply a typology of its various manifestations that would integrate most of the criteria brought up in previous attempts. In the final part of the dissertation, I have brought together what I regard as a series of genuine challenges to the best existing theories of metalinguistic discourse, and have attempted to frame what possible solutions could be.THINGS IN SENTENCES, INFINITE LEXICON? P-ÊÊ UNE CODA APRÈS RECA + CHAPTER 8***The very notion of metalanguage originated in formal logic in the first half of the 20th c. Soon, some of the concepts developed by logicians were taken over by philosophers of language (and subsequently by a few linguists). That was notably the case with the distinction between the use and the mention of a linguistic sequence; use designating the ordinary, transparent, employment of an expression to denote something outside language and mention its being chosen as a topic for discussion. When the subject came under the scrutiny of philosophers of language, the essentially prescriptive approach of the logician (the logician decreed which features his languages and metalanguages should possess), was turned into an attempt at describing actual linguistic mechanisms. It is in this tradition that I situate myself.Philosophers of language have turned out to be particularly interested in quotation (the mention of linguistic expressions), but I have thought it useful to introduce a term that covered not just quotation, but also mention-without-quote-marks, as well as hybrid cases like example 5. This term is reflexive metalinguistic demonstration, but for convenience’ sake I shall make do with metalinguistic demonstration.In Chapter 2, I have examined in detail the main theories of metalinguistic demonstration put forward in the course of the 20th c. namely the Name, Description, Demonstrative and Identity theories. In the process, I have been able to gradually identify the various properties of metalinguistic demonstrations that should be regarded as essential. And I have also formed a clearer idea of the body of data that a theory should be able to account for. In the end, I have been able to outline what I believe is a sound theory of metalinguistic demonstrations. This theory is chiefly informed by the proposals of François Recanati (2000, 2001), supplemented with insights of Paul Saka (1998), both of whom are indebted to the Demonstrative and Identity accounts.My reasons for using Recanati (2001) as the backbone of my own theory are the following. Recanati has successfully drawn the line between two types of meaning conveyed by metalinguistic demonstrations, namely ‘pictorial’ and ‘conventional linguistic’ meaning, something that had not been done with that clarity before. Besides, he has had the wisdom to give up the standard assumption that all metalinguistic demonstrations are referential, an assumption that inevitably led to theoretical dead ends. Moreover, drawing on the first two insights, Recanati has also separated out the syntactic and pragmatic aspects that were often confused in previous approaches.There is no doubt that the theory put forward by Recanati in 2001 is the most empirically adequate that can be found in the literature. Besides, it also accounts for an impressive range of key properties. Still, there are two interesting properties that received very little attention from Recanati, that is, referential diversity and recursiveness. Though Paul Saka has argued in favour of both in a 1998 paper, I believe his defence to have been somewhat clumsy. And therefore I have tried to offer more convincing evidence in favour of these properties.Let’s start with ReferenceAs Recanati has shown, not all metalinguistic demonstrations are referential expressions. But there is one aspect of reference that he says very little about: the sort or sorts of referents that a referential autonym can have. The theory implicitly suggests that autonyms can only refer to types. (Many writers have claimed more robustly and more explicitlythat there was only one sort of referents for autonyms, always either types or classes of tokens).I hold this view to be incorrect. As I’ve indicated in Chapter 4 of the thesis, I believe that several sorts of referents must be distinguished. Let us have a few examples:Run is a verbRun has three lettersShe said, “I ain’t EVER gonna tell ya”The first refers to a lexeme, since the predicate applies to runs, ran, running, as well.The second, only to a form (since not true of running or runs).Both could still be said to be abstract objects, and one might wish to call these ‘types’.The third, however, well and truly seems to refer to a token, the particular utterance produced by the woman behind she, witness the mimicry involved in the direct speech report.In my discussion of the next property, I offer a further argument in favour of referential diversity.2. Metalinguistic demonstrations can be iterated (repeated), a property usually described as recursiveness, and which has given rise to some controversies. Some demonstrativists, notably Cappelen & Lepore, because they hold the interior of a quotation to be semantically inert, have rejected the idea of recursiveness. I think, however, that their rejection comes from their failure to discern several types of recursiveness. In my dissertation, I have distinguished three; I shall only sketch two here.“ ‘Boston’ ” is an autonym.Typographical recursiveness: hardly very interesting, since it is a mechanical operation that can be repeated at will.The next pair of examples throws a more interesting light on the matter:‘Boston’ is a six-letter word.In each utterance of the previous example, “ ‘Boston’ ” is used to refer to an orthographic formBoston enclosed in two pairs of quote marks refers to particular tokens of Boston in a single pair of quote marks, as are produced when uttering a token of the first sentence, ‘Boston’ is a six-letter word. In each utterance of that sentence, the subject, ‘Boston’, itself refers, this time to the name Boston. This means that we have a situation in which an autonym refers to another autonym which also refers: reference here is iterated.This is actually no problem for the assumption of the inertness of the interior of the quotation, because reference is directed outwards: the interior of the quotation itself (the token displayed) remains inert. Note that referential recursiveness is only possible when one has a meta-quotation that refers to a token that is itself a referential autonym. This confirms the need for the theory to accommodate reference to particular tokens.I have made further use of the theory of metalinguistic demonstrations in Chapter 6 of the thesis, which is devoted to sketching a typology of metalinguistic demonstrations. In this connection, I have tried to bring together different types of discriminating factors that had been used in previous classifications (syntactic, semantic, pragmatic, typographical, lexical). These did not seem to be compatible from the outset, but then I realised that they might perhaps all be integrated into a single typology if I adopted an interpreter’s perspective. I reflected that that perspective provided a criterion for determining which characteristics of metalinguistic demonstrations would count as relevant variables for a typology: only those that made a ‘difference for the interpreter’ (i.e. affected his/her interpretative processes) would be retained.I also took advanatge of the general theory for the interpretation of utterances that has been set out in some recent publications, notably by Bach and Recanati (and which I outline in Chapter 3 of the thesis), and eventually reached what I regard as a decent result. Moreover, I also made a couple of interesting discoveries. The first one is that quite a bit of the interpretation of an utterance takes place at a ‘pre-interpretative’ level, that is, befor a sentence has been clearly identified (disambiguated). In particular, there are significant pictorial aspects of metalinguistic demonstrations that enter into the disambiguation process rather than into interpretation proper. The second one is that there is an impressive number of aspects of meaning that are linked to the speaker’s intentions, and should theoretically require access to the wide context of an utterance to be processed, that can be accessed at very low (semantic) levels of interpretation.In the final part of this presentation, I wish to examine a couple of instances of hybridity that face the theory with a more serious challenge than example 5 on the first slide. That example was easily explained in terms of simultaneous use and mention (the standard account in the literature): the same sequence, military action, was used ordinarily and, secondarily, demonstrated as being a particular form of euphemism. Other hybrids, on the other hand, do not lend themselves to such an analysis in a straightforward way. The first example I wish to bring up raises an interesting problem in connection with the notion of grammaticality:Robbe-Grillet describes himself in his introduction as “volontiers professeur de moi-même”.This can be rewritten as a pair of sentences, one for use the other for mention. We get:Use :Robbe-Grillet describes himself in his introduction as volontiers professeur de moi-même.Mention :Robbe-Grillet uses the expression “volontiers professeur de moi-même”.Although the mention line raises no special issues, there are great doubts as to the grammaticality of the ordinary-use line: a language-shift occurs in the middle of the sentence, and is not signalled by any marker, unlike in the initial hybrid. Though Recanati’s framework allows for language-shifts, and could therefore be relied on to argue that the correct interpretation can be ascribed to the French words in the example, it does not state rules determining at which spot in an utterance such a shift is acceptable grammatically. In other words, it says nothing about the possibility of a grammar that would straddle English and French. Fortunately, the idea of such grammars is supported by the limited research that has been carried out about code-switching. So, there may be theoretical backing for the assumption that the use line may after all be grammatical (with respect to a hybrid grammar).Note that these remarks are valid, I believe, not just for the use line of the twofold paraphrase, but for the initial hybrid too. Indeed, it is not clear — though some would be ready to say so — that the presence of quote marks is enough to alter the grammaticality of an utterance.Note also that an example like the previous one is a reminder of an essential fact about the work of language scholars: they start out to describe and/or explain some empirical data they find significant. But as things get more complicated, they must continually make decisions as to what must be acknowledged as relevant data for their research. Every step of the way, there may be a temptation to dismiss data — in the present case, on grounds of ungrammaticality — because these data threaten the validity of the theory being devised. Here, thanks to an analogy with grammatical accounts of code-switching, a case can be made for the grammaticality of utterances like the one under consideration. It is these kinds of extensions that broaden the linguist’s horizons and make research worthwhile.The second example I wish to examine raises interesting issues concerning iconicity. Though I have said nothing about it so far, iconicity is perhaps the single most important notion in any discussion of metalinguistic demonstration. In a nutshell, the basic assumption about ‘how such a demonstration makes sense’ is that the tokens displayed in a mentioning utterance are iconically related to the target of the demonstration. Iconicity can initially be understood as a matter of formal resemblance (cf the first batch of examples on Slide 1). The following example shows that the notion must be made more flexble than that:Descartes said that man “is a thinking substance”.Use: Descartes said that man is a thinking substance.Mention: Descartes said “is a thinking substance”.It can be seen that the mention line of the paraphrase is truth-conditionally incorrect: Descartes did not produce a token of is a thinking substance, since he was writing in Latin, not English. What Descartes said was est res cogitans. This might be taken to imply that the relation between the English tokens displayed and the Latin target is not a matter of iconicity. I would, with several other writers, suggest another direction: There is iconicity in this example, but the concept must be understood to be flexible and adaptable to contextual constraints. I believe such a conception to be necessary if one wants to be able to account for metalinguistic demonstrations within a single explanatory framework. There are too many instances of quotations that are not supported by formal identity to maintain a rigid notion of iconicity. I have added a last example on the slideConclusionAlthough I originally aspired to a comprehensive survey of things metalinguistic, I cannot but concede that there are still multiple aspects of the reflexive use of language that need looking into. I believe, however, that I have been able to shed some light on some areas of the debate. For instance, I believe that my discussion of the recursiveness and referential diversity of autonyms goes one step further than previous discussions. In particular, I hope to have been able to show convincingly that, contrary to a widespread opinion, an autonym can refer to various object, notably individual tokens. When these results are added to an excellent theory like Recanati’s, one ends up with a powerful explanatory apparatus. Moreover, this apparatus has the added advantage that it can easily be integrated into the general theory for the interpretation of utterances which I have alluded to before.I have taken advantage of this compatibility to outline my interpreter’s typology of metalinguistic demonstrations. Whether that effort was entirely successful or not, I think it has incidentally provided an excellent testing ground for the general theory. If only in that respect, the attempt was worth a try, since it shed light on the importance of pre-interpretative processes and on the conventional encoding of aspects of meaning that are otherwise heavily dependent on speaker’s intentions.Finally, I believe that the work doen in Chapter 8 has brought to the fore a number of question that deserve to be investigated at greater length in future. There are still dark areas in the study of world/language hybrids, but there also more general questions, e.g. regarding grammaticality and iconicity that need looking into. / Doctorat en philosophie et lettres, Orientation langue et littérature / info:eu-repo/semantics/nonPublished

This thesis is based and developed on the ambiguous and open conception, iconic species, which reveals the relationship between human society and non-human species that goes be- yond its biological status. From the case of the giant panda, I attempt to deconstruct the shap- ing process of an iconic species from multiple perspectives, which includes how a specific cultural context, or a specific historical period contributes to the shaping process and how the government and the public diverge or even clash around the shaping process. Then, I introduce my fieldwork where I through observing both giant pandas and red pandas in the exhibition centres called panda bases to analyse the encountering an iconic species in reality and their different influences on public awareness of the wildlife conservation. I also attempt to explore the various representative forms of an iconic species such as the Tibetan antelope ranging from the mascot to the film and follow the changes of its symbolic meanings in different forms. In conclusion, the thesis is aimed to reflect the hybrid features of the iconic species and pro- vide in-depth interpretation of the endless interactions between the human beings and other species.
