Yablo's paradox and referring to infinite objects

The blame for the semantic and set-theoretic paradoxes is often placed on self-reference and circularity. Some years ago, Yablo [1985; 1993] challenged this diagnosis, by producing a paradox that's liar-like but does not seem to involve circularity. But is Yablo's paradox really non-circular? In a recent paper, Beall [2001] has suggested that there are no means available to refer to Yablo's paradox without invoking descriptions, and since Priest [1997] has shown that any such description is circular, Beall concludes that Yablo's paradox itself is circular. In this paper, we argue that Beall's conclusion is unwarranted, given that (1) descriptions are not the only way to refer to Yablo's paradox, and (ii) we have no reason to believe that because the description involves self-reference, the denotation of the description is also circular. As a result, for all that's been said so far, we have no reason to believe that Yablo's paradox is circular.

A conspiracy theory for clefts : the syntax and interpretation of cleft constructions

O objetivo final deste estudo é contribuir para a discussão sobre qual a medida em que conceitos semânticos e discursivos estão sintaticamente codificados. Mais especificamente, investiga-se se existe alguma correlação consistente entre alguns aspetos interpretativos e sintáticos de quatro construções clivadas do Português Europeu, e como se deve dar conta teoricamente destas potenciais correlações. As clivadas consideradas são as clivadas canónicas, as pseudoclivadas, as clivadas de é que e as clivadas de SER. Sintaticamente podemos distinguir dois tipos: clivadas bioracionais (canónicas e pseudoclivadas) e clivadas mono-oracionais (clivadas de é que e de SER). Todas as estruturas têm um constituinte clivado focalizado que pode constituir tanto um foco informacional como um foco contrastivo, e uma oração clivada que introduz uma pressuposição existencial. Adicionalmente, o constituinte clivado identifica exaustivamente uma posição vazia na oração clivada. Adota-se a semântica alternativa para o foco (Rooth 1985), segundo a qual o foco entoacional contribui uniformemente um conjunto de alternativas na Forma Lógica. Regras pragmáticas operando neste conjunto dão origem a duas implicaturas que podem ser suspensas: pressuposição existencial e exaustividade. Dado que as clivadas de é que e as de SER têm a mesma interpretação que orações não-clivadas, conclui-se que a sua estrutura sintática particular não contribui para estas propriedades interpretativas. Em contrapartida, as clivadas bioracionais, que são orações copulativas especificacionais, têm uma presuposição existencial e uma interpretação exaustiva que não pode ser suspensa, tal como as orações especificacionais não-clivadas. Argumenta-se que isto se deve ao facto de o constituinte clivado identificar uma variável introduzida por uma descrição definida. Demonstra-se que a oração clivada, uma relativa em posição de complemento de um determinador definido nas clivadas canónicas e uma relativa livre nas pseudoclivadas, tem a mesma denotação que um DP definido, e portanto tem uma pressuposição existencial inerente. A interpretação exaustiva deve-se à relação identificacional entre o constituinte clivado e a descrição definida. Além disso, defende-se que em Português Europeu um traço de foco não desencadeia movimento-A’ para um FocP especializado. Os constituintes focalizados movem-se antes por razões independentes do foco. Isto é confirmado pelo facto de apenas o constituinte clivado das clivadas de é que ter propriedades de movimento A’, os outros parecem estar in situ. Propõe-se que o constituinte clivado das clivadas de é que é um tópico com um traço de foco que se move para um TopP. Esta análise dá conta da existência de restrições discursivas semelhantes para tópicos não focalizados e para o constituinte clivado das clivadas de é que. O traço quantificacional de foco arrastado pela topicalização dá origem a efeitos de intervenção, causando a não-recursividade do foco na periferia esquerda e a sua incompatibilidade com movimento de outros constituintes com traços quantificacionais. A análise prediz as restrições de encaixe observadas para as clivadas de é que. Finalmente, desenvolve-se uma análise sintática das clivadas de SER que aproxima estas estruturas das estruturas com partículas de foco. Propõe-se que a cópula é um operador sensível ao foco que é merged juntamente com o constituinte clivado. As restrições distribucionais da cópula devem-se a requisitos selecionais de núcleos.

Emphatic Polarity from Latin to Romance

This paper offers an analysis of some emphatic polarity constructions in Spanish and Catalan from a diachronic and comparative perspective. We focus on the syntactic processes involved in the verbalization of this polarity, in both its positive and negative expression. Our main proposal is that the markers used in Spanish and Catalan (as well as other Romance languages) to reinforce polarity have acquired their status as the consequence of a focalization process. It will be argued that these elements have undergone leftward movement from their base-generated hierarchically low position to a prominent position in the left periphery of the sentence (see Rizzi 1997) and subsequently experienced a progressive bleaching of their original value (which is related to a verbal denotation) to end up being reanalyzed / grammaticalized as polarity markers

Wörter stehen da einige. On nominal split topicalization in non-standard viennese german

This work investigates the syntactic, semantic, and pragmatic properties of nominal Split Topicalization (ST) constructions in Standard and non-Standard German. The topic phrase denotes a property, and the MF phrase either modifies this property or picks out a specific entity. Semantically, the topic phrase will be analysed as a property-denoting expression which restricts the denotation of the verbal predicate, while the MF phrase is composed either via specify or restrict (cf. Chung and Ladusaw, 2003). Syntactically, the base position of the topic phrase is the (incorporating) verb, and the MF phrase is generated independently as the complement of the verb containing an empty pronoun. Since predicates introduce abstract discourse referents, the topic phrase can be resumed via "pro" in the MF phrase.

The concept of emerging power in international politics and economy

ABSTRACT This paper aims to analyze the concept of emerging power established to the understanding of international affairs. The work observes that the use of the lexicon emerging - regarding to markets, countries or powers - as qualifier for a range of international relations phenomena became a constituent part of the matter. In spite of that, the empirical denotation of the predicate is ahead of the amount of efforts on its theoretical contextualization. Our methodological hypothesis is that the rational denial of the concepts prevailing connotative spectrum by acknowledging the embedded wisdom about cognate phenomena synthesizes a theoretical framework on its accurate use.

A review of pharmacokinetic parameters of metabolites and prodrugs

In drug discovery and development, the kinetic study of active metabolites plays an important role, helping to define the time course of the drug in the body and its activity or toxicity. After a pharmacokinetics assessment of a drug and its metabolite or a prodrug and its parent-drug, several parameters can be calculated. In some cases, achieving the objective of the study does not require all possible parameters to be calculated. When parameters are calculated, it is essential that their denotations are widely accepted and used. However, some parameters undergo a certain variability of denotation, which may confuse some readers. Thus, this review summarizes the current published data for experimental pharmacokinetic parameters of metabolites and the calculations involved in simple metabolite pharmacokinetic studies. It also evaluates the most common pharmacokinetic parameters in the literature and suggests metabolite parameters that could be determined to help advance metabolite kinetic models.

Identifizierung und Charakterisierung von Intermediärfilament-Organisatoren in Caenorhabditis elegans

Intermediärfilamente (IFs) sind neben Mikrotubuli und Aktinfilamenten die dritte filamentäre Komponente des Zytoskeletts. Sie wirken als mechanische Stabilisatoren, sind außerdem an Zelldifferenzierung, Proliferation und Apoptose beteiligt und tragen zu Zellpolarität bei. IFs sind dynamische Strukturen, die zelltypspezifisch in unterschiedlichen Anordnungen und Abundanzen vorkommen und von Signalkaskaden beeinflusst werden. Die zugrundeliegenden molekularen Mechanismen dieser fein abgestimmten Prozesse sind weitgehend unbekannt. In dieser Arbeit sollte deswegen ein Tiermodell entwickelt werden, um Regulatoren der IF-(Netzwerk)-Organisation in vivo zu untersuchen und zu identifizieren. Dazu wurde C. elegans ausgewählt, da es sich hierbei um einen genetisch gut charakterisierten und leicht manipulierbaren Organismus handelt, in dessen Genom elf Gene für zytoplasmatische IFs kodieren. Zunächst wurden stabil transgene C. elegans-Linien generiert, die fluoreszierende IFs exprimieren. Es konnte gezeigt werden, dass das darmspezifische IFB-2::CFP im Bereich des apikalen Junktionskomplex verankert ist und nahezu vollständig im subapikalen Terminalgeflecht der Enterozyten lokalisiert, das als Teil der endotube besonders stabil und widerstandsfähig ist. Wenn diese Tiere mit dsRNA gegen das ebenfalls im Terminalgeflecht exprimierte IF ifc-2 behandelt wurden, entwickelten sich blasenförmige Ausstülpungen des Darmlumens, die auf eine Schwächung der rigiden und formgebenden endotube hinwiesen und damit einen direkten in vivo-Beweis für die stressprotektive Funktion des intestinalen IF-Netzwerks lieferten. Die leichte Detektierbarkeit des IFB-2::CFP-Musters wurde in einem optischen Screen ausgenutzt, bei dem nach chemischer Mutagenese nach Veränderungen im IF-Muster gefahndet wurde. Hierbei wurden drei Mutanten isoliert. In Komplementationsanalysen stellte sich heraus, dass es sich in zwei Fällen um Allele desselben Gens handelt. Die Identifizierung der betroffenen Gene gelang durch eine PCR-basierte Kartierung von single nucleotide polymorphisms nach Verpaarung mit dem Hawaii-Stamm (snp-mapping) und anschließender RNAi-Analyse der Einzelgene in den identifizierten Chromosomenabschnitten. Im einen Fall handelte es sich um das sma-5-Gen, einer Serin/Threonin-Kinase mit Homologie zu den MAP-Kinasen MAPK7/ERK5 der Säuger. Hier wurden, ebenso wie beim ifc-2 (RNAi)-Phänotyp, progressive blasenförmige Ausstülpungen des Darmlumens beobachtet. Die beiden anderen Allele tragen Mutationen in einem bisher nicht näher charakterisierten Gen. In diesen Würmern kommt es zu einem vollständigen Auflösung des IFB-2::CFP-Netzwerks mit prominenten Akkumulationen um die apikalen Junktionen. Das Darmlumen ist stellenweise geweitet und das elektronendichte Terminalgeflecht fehlt fast vollständig, die Integrität des Darmepithels ist jedoch nicht kompromittiert. Die anderen IFs des Terminalgeflechts sind ebenfalls fehlverteilt, und die intestinale Expression von Aktin ist stark reduziert. Expressionskonstrukte des Gens zeigten weiterhin, dass es darmspezifisch synthetisiert wird und mit den IFs im Terminalgeflecht kolokalisiert. Das Protein ist, ähnlich wie das IF-assoziierte Filaggrin der Säuger ausgesprochen histidinreich. Es enthält außerdem eine Prolin-reiche Domäne, die Teil einer potentiellen Aktin-Bindedomäne ist. Auf Grund all dieser Eigenschaften wird die Bezeichnung IFO-1 (intermediate filament organizer) für das neue Protein vorgeschlagen, das möglicherweise als struktureller Zytoskelett-Linker wirkt. Die vorgestellten Ergebnisse untermauern die Bedeutung von C. elegans für die Identifizierung von Faktoren, die IF-Netzwerke regulieren, und die Möglichkeit, Defekte im lebenden Gesamtorganismus zu bestimmen.

The Representation of Motherhood in Polish Cinema

The project aimed to analyse representations of motherhood in Polish cinema as a special case of a more general system within the representation of women. It concentrated on the image of the Polish Mother created during the 19th century in Polish culture under the influence of specific political, social and religious factors. Ms. Ostrowska's initial hypothesis was that this symbolic image became one of the most stable elements in Polish cinema and as her research revealed, it was valuable for the preservation of national identity but nevertheless a fiercely constraining model for Polish femininity. In order to fully understand the nature of this persistent image it was initially necessary to related it to broader contexts and issues in representation. These included the image of the Polish Mother within general mythological structures (using the notion of myth in the Barthesian sense). Following her initial research Ms. Ostrowska felt that it was most appropriate to view the myth of the Polish Mother as a dominant ideological structure in the discourse of motherhood within Polish culture. An analysis of the myth of the Polish Mother can provide an insight into how Polish society sees itself at different periods in time and how a national identity was constructed in relation to particular ideological demands stemming from concrete historical and political situations. The analysis of the film version of this myth also revealed some aspects of the national character of Polish cinema. There the image of woman has become enshrined as the "eternal feminine", with virtues which are inevitably derived directly from Catholicism, particularly in relation to the networks of meanings around the central figure of Mary, Mother of God. In 19th century Poland these were linked with patriotic values and images of woman became part of the defence of the very idea of Poland and Polishness. After World War Two, this religious-political image system was adapted to the demands of the new communist ideology. The possibility of manipulating the ideological dimensions of the myth of the Polish Mother is due to the very nature of the image, which as a symbol of civil religion had been able to function independently of any particular state or church institution. Although in communist ideology the stress was on the patriotic aspect of the myth, its pronounced religious aspect was also transmitted, consciously or not, in the denotation process, this being of great significance in the viewer's response to the female character. This appropriation of elements derived from the national patriotic tradition into the discourse of communist ideology was a very efficient strategy to establish the illusion of continuity in national existence, which was supposed to convince society of the rightness of the new political situation. The analysis of films made in the post-war period showed the persistence of this discourse on motherhood in a range of cinematic texts regardless of the changing political situation. Ms. Ostrowska claims that the stability of this discursive formation is to a certain extent the result of the mythological aspect of the mother figure. This mythological structure also belongs to the ideology of Romanticism which in general continues to prevail in Polish cultural discourse as a meta-language of national community. The analysis of the films confirmed the hypothesis of the Polish Mother as a myth-sign whose signifier is stable whereas the signified depends on the specific historical conditions in which it is set. Therefore in the famous propaganda documentary Kobiety naszych dni (Women of Our Days, 1951) by Jan Zelnik, and in other films made after the October 1956 "thaw" it functions as an "empty sign. She concludes that it would be difficult to deny that the myth of the Polish Mother has offered Polish women a special role in national life, granting them a high moral position in the social, hierarchy. However the processes of idealisation involved have resulted in a deprivation of her subjectivity and the right to decide about her own life. This idealisation also served to strengthen traditional patriarchal structures through this set of female obligations to the mother land. In Polish ideology it is not a man who demands sacrifice from a woman but the motherland, which, deprived of the institutions of male power for nearly 150 years, had functioned as a feminine structure. That is why oppressive aspects of the myth have been obscured for so long. While Polish women were doubtless able to accept the constrictions because of their sense of national duty and any misgivings were overridden by the argument of the cause, it is important to recognise that the strength of these constructions, compounded by the ways in which they spoke of and continue to speak of a certain perfection, make them persist into contemporary Poland. Poland is however no longer embattled and the signs that made these meanings are potentially empty. This space for meaning will be and is already being contested and increasingly colonised by current western models of femininity. Ms. Ostrowska's final question is whether this will help to prevent a possible resentful victimisation of the silent and noble Polish Mother.

Community

The term community in the English language can be traced back to the 14th century and originates from the French word comuneté and the Latin word communitatem. In English the term initially came to denote five distinct senses. Community served as a distinction of the common people from those of rank (1), as a denotation of a state or organized society (2), the people of a district (3), as a designation for the community of shared interests (4) and as a sense of common identity and characteristics (5). In these early meanings of the term it is important to note the distinction between the designation of actual social groups on the one hand and the indication of a particular relational quality on the other.
