O repertório cerâmico da sala nº 1(Vidigueira), na sequência Neolítico final e Calcolítico do Alentejo Médio

O trabalho aqui proposto tem como objectivo central, a realização de análises ao conjunto dos recipientes cerâmicos pertencentes ao povoado da Sala nº1. Repertório esse, que se baseou no acervo retirado do sítio arqueológico Sala nº1, intervencionado pelo Professor Victor S. Gonçalves (1988, 1989 e 1995). As análises e descrições efectuadas foram sempre norteadas para a tentativa de estabelecer uma sequência de formas que se pudesse verificar quanto à sua normalização e frequência nos contextos presentes ao povoado da Sala nº1. Traduzindo nessa realidade, a diacronia transversal entre os estratos arqueológicos pertencentes ao Neolítico final e os estratos pertencentes ao Calcolítico. Tendo sempre como parâmetros de análise, as metodologias e critérios descritivos dos recipientes cerâmicos, presentes nos trabalhos publicados sobre as realidades cronológicas semelhantes no Sul de Portugal. O próprio conjunto de recipientes cerâmicos aqui analisado foi submetido a essas metodologias, com fim de obter primordialmente as formas e as tipologias a que pertencem. Nesse sentido procurei criar um quadro de referência local e regional, e posteriormente coloca-lo num enquadramento geral do Neolítico final e início do Calcolítico do Alentejo Médio, tentando verificar as similitudes nos quadros tipológicos existentes, como os estabelecidos por Carlos Tavares da Silva e Joaquina Soares. Sendo este um estudo que abrange um tempo cronológico de praticamente 1500 anos, premiei através da amplitude dos contornos que moldaram esta análise, algumas perspectivas possíveis. Quer ao nível das tipologias, quer ao nível das estratégias de ocupação do território, aplicáveis para o espaço e o tempo em análise. Verificando a realidade escassa nos contextos alentejanos (publicados), em que a cultura material se integra numa estratigrafia e cronologias com uma diacronia semelhante à do povoado da Sala nº1. Tentei integrar este povoado num estudo que não sendo comparativo, tivesse essa componente em relação às tipologias e formas cerâmicas identificadas. Procurou-se dar enfase à realidade artefactual das taças carenadas, e à sua possível evolução para formas mais adaptáveis ao uso e consumo quotidiano das comunidades contemporâneas das fases Calcolíticas do povoado.

Cappadocia: where Greek prepositions come to die

The Cappadocian variety of Ulaghátsh is unique among the Greek-speaking world in having lost the inherited preposition ‘se’. The innovation is found with both locative and allative uses and has af-ected both syntactic contexts in which ‘se’ was originally found, that is, as a simple preposition (1) and as the left-occurring member of circumpositions of the type ‘se’ + NP + spatial adverb (2). (1) a. tránse ci [to meidán] en ávʝa see.PST.3SG COMP ART.DEF.SG.ACC yard.SG.ACC COP.3 game.PL.NOM ‘he saw that in the yard is some game’ (Dawkins 1916: 348) b. ta erʝó da qardáʃa évɣan [to qonáq] ART.DEF.PL.NOM two ART.DEF.PL.NOM friend.PL.NOM ascend.PST.3PL ART.DEF.SG.ACC house.SG.ACC ‘the two friends went up to the house’ (Dawkins 1916: 354) (2) émi [ta qonáca mésa], kiríʃde [to ʝasdɯ́q píso] enter.PST.3SG ART.DEF.PL.NOM house.PL.ACC inside hide.PST.3SG. ART.DEF.SG.ACC cushion.SG.ACC behind ‘he went into the houses and hid behind the cushions’ (Dawkins 1916: 348) In this paper, we set out to provide (a) a diachronic account of the loss of ‘se’ in Asia Minor Greek, and (b) a synchronic analysis of its ramifications for the encoding of the semantic and grammatical functions it had prior to its loss. The diachronic development of ‘se’ is traced by comparing the Ulaghátsh data with those obtained from Cappadocian varieties that have neither lost it nor do they show signs of losing it and, crucially, also from varieties in which ‘se’ is in the process of being lost. The comparative analysis shows that the loss first became manifest in circumpositions in which ‘se’ was preposed to the complement to which in turn a wide range of adverbs expressing topological relations were postposed (émi sa qonáca mésa > émi ta qonáca mésa). This finding is accounted for in terms of Sinha and Kuteva’s (1995) distributed spatial semantics framework, which accepts that the elements involved in the constructions under investigation—the verb (émi), ‘se’ and the spatial adverb (mésa)—all contribute to the expression of the spatial relational meaning but with differences in weighting. Of the three, ‘eis’ made the most minimal contribution, the bulk of it being distributed over the verb and the adverb. This allowed for it to be optionally dropped from circumpositions, a stage attested in Phlo-tá Cappadocian and Silliot, and to be later completely abandoned, originally in allative and subsequently in locative contexts (earlier: évɣan so qonáq > évɣan to qonáq; later: so meidán en ávʝa > to meidán en ávʝa). The earlier loss in allative contexts is also dealt with in distributed semantics terms as verbs of motion such as έβγαν are semantically more loaded than vacuous verbs like the copula and therefore the preposition could be left out in the former context more easily than in the latter. The analysis also addresses the possibility that the loss of ‘se’ may ultimately originate in substandard forms of Medieval Greek, which according to Tachibana (1994) displayed SPATIAL ADVERB + NP constructions. Applying the semantic map model (Croft 2003, Haspelmath 2003), the synchronic analysis of the varieties that retain ‘se’ reveals that—like many other allative markers crosslinguistically—it displays a pattern of multifunctionality in expressing nine different functions (among others allative, locative, recipient, addressee, experiencer), which can be mapped against four domains, viz. the spatiotemporal, the social, the mental and the logicotextual (cf. Rice & Kabata 2007). In Ulaghátsh Cappadocian, none of these functions is overtly marked as such. In cases like (1), the intended spatial relational meaning is arrived at through the combination of the syntax and the inherent semantics of the verb and the zero-marked NP as well as from the context. In environments of the type exemplified by (2), the adverb contributes further to the correct interpretation. The analysis additionally shows that, despite the loss of ‘se’, Ulaghátsh patterns with all other Cappadocian varieties in one important aspect: Goal and Location are expressed similarly (by zero in Ulaghátsh, by ‘se’ in the other varieties) whereas Source is being kept distinct (expressed by ‘apó’ in all varieties). Goal-Location polysemy is very common across the world’s languages and, most crucially, prevails over other possible polysemies in the tripartite distinction Source—Location—Goal (Lestrade 2010, Nikitina 2009). Taking into account this empirical observation, our findings suggest that the reor-anisation of spatial systems can have a local effect—in our case the loss of a member of the prepositional paradigm—but will keep the original global picture intact, thus conforming to crosslinguistically robust tendencies.  References Croft, W. 2001.

Utopia and its Discontents: Dreams of Catastrophe and the End of 'the End of History'

The institutionalization of Utopia Studies in the last decade is premised upon a specifically aesthetic reception of Ernst Bloch’s theory of the “utopian impulse” during the 1980s and 1990s. A postmodern uneasiness to both left and right formulations of the "End of History" during this period imposes a resistance to concepts of historical and political closure or totality, resulting in a "Utopianism without Utopia". For all the attractiveness of this pan-utopianism, its failure to consider the relation between historical representation and fulfillment renders it consummate with liberalism as a merely inverted conservatism. In contrast to this specific recuperation of a Bloch, the continuing importance of Walter Benjamin’s theory of the dialectical image and the speculative concept of historical experience which underlies it becomes apparent. The intrusion of the historical Absolute is coded throughout Benjamin’s thought as the eruptive and mortuary figure of catastrophe, which stands as the dialectical counterpart to the utopian wish images of the collective dream. Indeed, the motto under which the Arcades Project was to be constructed derives from Adorno: “Each epoch dreams of itself as annihilated by catastrophe”.

From syntagmatic to paradigmatic spatial zeroes: the loss of the preposition se in inner Asia Minor Greek

We trace the diachronic development of the preposition se in inner Asia Minor Greek from its use to mark a range of spatial functions to its ultimate loss and replacement by zero. We propose that, before spreading to all syntactic and semantic contexts, zero marking was contextually-dependent on the presence/absence of a prenominal genitive modifying the head noun of Ground-encoding NPs and on the presence/absence of Region-encoding postpositions. We attribute these developments to an informational load relief strategy aimed at producing more economical utterances as well as to language contact with Turkish, which favoured structural convergence on the adpositional level between the two languages.

Transmitting Chinese Medicine: Changing Perceptions of Body, Pathology, and Treatment in Late Imperial China

Historians of Chinese medicine acknowledge the plurality of Chinese medicine along both synchronic and diachronic dimensions. Yet, there remains a tendency to think of tradition as being defined by some unchanging features. The Chinese medical body is a case in point. This is assumed to have been formalised by the late Han dynasty around a system of internal organs, conduits, collaterals, and associated body structures. Although criticism was voiced from time to time, this body and the micro/ macrocosmic cosmological resonances that underpin it are seen to persist until the present day. I challenge this view by attending to attempts by physicians in China and Japan in the period from the mid 16th to the late 18th century to reimagine this body. Working within the domain of cold damage therapeutics and combining philological scholarship, empirical observations, and new hermeneutic strategies these physicians worked their way towards a new territorial understanding of the body and of medicine as warfare that required an intimate familiarity with the body’s topography. In late imperial China this new view of the body and medicine was gradually re-absorbed into the mainstream. In Japan, however, it led to a break with this orthodoxy that in the Republican era became influential in China once more. I argue that attending further to the innovations of this period—commonly portrayed as one of decline—from a transnational perspective may help to go beyond the modern insistence to frame East Asian medicines as traditional.

Alright: a distinctive pathway of change from the 18th century to the present day

The origins of the vast majority of the words we use in contemporary English go back as far as Old or Middle English. In contrast, alright and all right in their present-day application appear to be the result of a more recent evolution, as there is no evidence of their use, not even in the two-word form, in the published fiction before the 18th century. Furthermore, there are not in the research literature, at least to my knowledge, any previous linguistic studies on this specific subject matter. The present article is simply an attempt to describe the various processes of diachronic change that brought about the emergence of alright.

Hierarchy and Expansiveness in Two-Dimensional Subshifts of Finite Type

Subshifts are sets of configurations over an infinite grid defined by a set of forbidden patterns. In this thesis, we study two-dimensional subshifts offinite type (2D SFTs), where the underlying grid is Z2 and the set of for-bidden patterns is finite. We are mainly interested in the interplay between the computational power of 2D SFTs and their geometry, examined through the concept of expansive subdynamics. 2D SFTs with expansive directions form an interesting and natural class of subshifts that lie between dimensions 1 and 2. An SFT that has only one non-expansive direction is called extremely expansive. We prove that in many aspects, extremely expansive 2D SFTs display the totality of behaviours of general 2D SFTs. For example, we construct an aperiodic extremely expansive 2D SFT and we prove that the emptiness problem is undecidable even when restricted to the class of extremely expansive 2D SFTs. We also prove that every Medvedev class contains an extremely expansive 2D SFT and we provide a characterization of the sets of directions that can be the set of non-expansive directions of a 2D SFT. Finally, we prove that for every computable sequence of 2D SFTs with an expansive direction, there exists a universal object that simulates all of the elements of the sequence. We use the so called hierarchical, self-simulating or fixed-point method for constructing 2D SFTs which has been previously used by Ga´cs, Durand, Romashchenko and Shen.

Marginal/minority popular music : the concept of the "third space" and the case for "hybridities" of cultures/identities /

The topic of this thesis is marginaVminority popular music and the question of identity; the term "marginaVminority" specifically refers to members of racial and cultural minorities who are socially and politically marginalized. The thesis argument is that popular music produced by members of cultural and racial minorities establishes cultural identity and resists racist discourse. Three marginaVminority popular music artists and their songs have been chosen for analysis in support of the argument: Gil Scott-Heron's "Gun," Tracy Chapman's "Fast Car" and Robbie Robertson's "Sacrifice." The thesis will draw from two fields of study; popular music and postcolonialism. Within the area of popular music, Theodor Adorno's "Standardization" theory is the focus. Within the area of postcolonialism, this thesis concentrates on two specific topics; 1) Stuart Hall's and Homi Bhabha's overlapping perspectives that identity is a process of cultural signification, and 2) Homi Bhabha's concept of the "Third Space." For Bhabha (1995a), the Third Space defines cultures in the moment of their use, at the moment of their exchange. The idea of identities arising out of cultural struggle suggests that identity is a process as opposed to a fixed center, an enclosed totality. Cultures arise from historical memory and memory has no center. Historical memory is de-centered and thus cultures are also de-centered, they are not enclosed totalities. This is what Bhabha means by "hybridity" of culture - that cultures are not unitary totalities, they are ways of knowing and speaking about a reality that is in constant flux. In this regard, the language of "Otherness" depends on suppressing or marginalizing the productive capacity of culture in the act of enunciation. The Third Space represents a strategy of enunciation that disrupts, interrupts and dislocates the dominant discursive construction of US and THEM, (a construction explained by Hall's concept of binary oppositions, detailed in Chapter 2). Bhabha uses the term "enunciation" as a linguistic metaphor for how cultural differences are articulated through discourse and thus how differences are discursively produced. Like Hall, Bhabha views culture as a process of understanding and of signification because Bhabha sees traditional cultures' struggle against colonizing cultures as transforming them. Adorno's theory of Standardization will be understood as a theoretical position of Western authority. The thesis will argue that Adorno's theory rests on the assumption that there is an "essence" to music, an essence that Adorno rationalizes as structure/form. The thesis will demonstrate that constructing music as possessing an essence is connected to ideology and power and in this regard, Adorno's Standardization theory is a discourse of White Western power. It will be argued that "essentialism" is at the root of Western "rationalization" of music, and that the definition of what constitutes music is an extension of Western racist "discourses" of the Other. The methodological framework of the thesis entails a) applying semiotics to each of the three songs examined and b) also applying Bhabha's model of the Third Space to each of the songs. In this thesis, semiotics specifically refers to Stuart Hall's retheorized semiotics, which recognizes the dual function of semiotics in the analysis of marginal racial/cultural identities, i.e., simultaneously represent embedded racial/cultural stereotypes, and the marginal raciaVcultural first person voice that disavows and thus reinscribes stereotyped identities. (Here, and throughout this thesis, "first person voice" is used not to denote the voice of the songwriter, but rather the collective voice of a marginal racial/cultural group). This dual function fits with Hall's and Bhabha's idea that cultural identity emerges out of cultural antagonism, cultural struggle. Bhabha's Third Space is also applied to each of the songs to show that cultural "struggle" between colonizers and colonized produces cultural hybridities, musically expressed as fusions of styles/sounds. The purpose of combining semiotics and postcolonialism in the three songs to be analyzed is to show that marginal popular music, produced by members of cultural and racial minorities, establishes cultural identity and resists racist discourse by overwriting identities of racial/cultural stereotypes with identities shaped by the first person voice enunciated in the Third Space, to produce identities of cultural hybridities. Semiotic codes of embedded "Black" and "Indian" stereotypes in each song's musical and lyrical text will be read and shown to be overwritten by the semiotic codes of the first person voice, which are decoded with the aid of postcolonial concepts such as "ambivalence," "hybridity" and "enunciation."

Les représentations sociales du politique: une analyse sémantique de l'idéologie nationale fédéraliste québécoise durant les deux périodes référendaires

Dans ce mémoire, nous proposons l’étude des représentations sociales du politique dans la presse quotidienne. Notre objet d’étude est le sens de la nation au Québec dans une période historique où la notion idéologique de nation s’avère un cadre de référence en profonde mutation dans de nombreuses sociétés. Plus particulièrement, nous voulons nous situer au centre des tensions à propos de la représentation sociale nationale en prenant comme observatoire un travail idéologique fédéraliste par des Québécois, qui à la fois se posent comme promoteurs de la nation, et visent une intégration dans un autre espace national et juridique : le Canada. Les résultats de cette étude qualitative sont issus d’une analyse sémantique du discours éditorial du journal La Presse. Nous avons ainsi examiné les différentes catégories de connaissance mobilisées lors de l’évocation de l’espace national, ainsi que la façon dont elles sont organisées au sein du discours lors des deux périodes référendaires, soit en 1980 et 1995. C’est donc dans le cadre d’une sociologie de la connaissance journalistique que nous menons cette étude. Le discours social, à partir de l’étude des théories des représentations sociales et de la sociologie des contenus médiatiques, ne peut se considérer qu’à travers l’ensemble des relations sociales dont il est le produit. Nous nous attachons ici à définir d’une part les spécificités du discours éditorial, et d’autre part les différentes catégories de connaissances utilisées dans notre corpus qui font sens. On perçoit alors, grâce à une description diachronique, l’évolution des représentations sociales ayant a trait à l’espace national québécois entre les deux périodes étudiées. Après avoir défini ce dont on parle lorsqu’il est question de l’espace national, nous nous emploierons à analyser la façon dont ce discours est organisé. Ainsi, nous mettons en avant d’une part, les différentes formes discursives, rhétoriques et argumentatives, mises en place dans le but de persuader et de justifier l’action (le rejet des deux référendums, et l’adhésion aux promesses de renouvellement du fédéralisme), et d’autre part la logique discursive mobilisée consistant à placer la nation comme un objet politique rationnel ou non. En effet, le discours éditorial nous permet de mettre au jour une organisation cognitive de la connaissance, qui à quelques nuances près, est structurée de façon manichéenne entre le rationnel (l’éditorialiste, le fédéralisme, l’économique, l’universalisme, la raison de sens commun) et l’irrationnel (le souverainisme, ses dirigeants n’étant que des rêveurs et des passionnés), se plaçant dès lors dans un rapport de communication politique, plus proche de la propagande que de l’exemplarité réflexive que pose le discours éditorial.

L’institutionnalisation de la migration masculine chez les Mossi : une étude d’un changement socioculturel au Burkina Faso

Depuis plus de cent ans, les Mossi du Burkina Faso évoluent avec les migrations de travail. Entre les travaux forcés de l’ère coloniale et les flux migratoires actuels, la migration est devenue une institution centrale chez les Mossi. Elle s’est imposée comme une solution aux bouleversements engendrés par de l’économie de marché, la dégradation de leur environnement et les tensions internes. Il s’est développé un système normatif qui soutient et qui perpétue ces comportements migratoires. Cette intégration institutionnelle a cependant engendré un affaiblissement de la gérontocratie et du patriarcat ce qui a déséquilibré l’organisation sociale « traditionnelle ». À partir de la méthode de l’anthropologie du changement social, ce mémoire propose une étude locale et diachronique des transformations générées par le processus migratoire. Il explique comment la migration s’est institutionnalisée, quelles sont les conséquences sur les rapports de pouvoir et quels sont les innovations, les résistances et les métissages qui en découlent. Ainsi, les migrations de travail devaient être une réponse à la crise socioéconomique vécue par les Mossi, mais par son institutionnalisation, elles sont également apparues être l’une des principales causes de cette crise.
