We investigate the possibility to characterize (multi) functions that are Σ b i -definable with small i (i = 1, 2, 3) in fragments of bounded arithmetic T 2 in terms of natural search problems defined over polynomial-time structures. We obtain the following results: (1) A reformulation of known characterizations of (multi)functions that are Σ b 1 - and Σ b 2 -definable in the theories S 1 2 and T 1 2 . (2) New characterizations of (multi)functions that are (...) Σ b 2 - and Σ b 3 -definable in the theory T 2 2 . (3) A new non-conservation result: the theory T 2 2 (α) is not ∀Σ b 1 (α)-conservative over the theory S 2 2 (α). To prove that the theory T 2 2 (α) is not ∀Σ b 1 (α)-conservative over the theory S 2 2 (α), we present two examples of a Σ b 1 (α)-principle separating the two theories: (a) the weak pigeonhole principle WPHP (a 2 , f, g) formalizing that no function f is a bijection between a 2 and a with the inverse g, (b) the iteration principle Iter (a, R, f) formalizing that no function f defined on a strict partial order ( $\{0,\dots,a\}$ , R) can have increasing iterates.

We investigate the problem how to lift the non - $\forall \Sigma^b_1(\alpha)$ - conservativity of $T^2_2(\alpha)$ over $S^2_2(\alpha)$ to the expected non - $\forall \Sigma^b_i(\alpha)$ - conservativity of $T^{i+1}_2(\alpha)$ over $S^{i+1}_2(\alpha)$ , for $i > 1$ . We give a non-trivial refinement of the “lifting method” developed in [4,8], and we prove a sufficient condition on a $\forall \Sigma^b_1(f)$ -consequence of $T_2(f)$ to yield the non-conservation result. Further we prove that Ramsey's theorem, a $\forall \Sigma^b_1(\alpha)$ - formula, is not provable (...) in $T^1_2(\alpha)$ , and that $\forall \Sigma^b_j(\alpha)$ - conservativity of $T^{i+1}_2(\alpha)$ over $T^{i}_2(\alpha)$ implies $\forall \Sigma^b_j(\alpha)$ - conservativity of the whole $T_2(\alpha)$ over $T^{i}_2(\alpha)$ , for any $j \geq 2$.

They work and live in Milan.Girls Just wanna have fun: Goldschmied & Chiari's Irreverent HumorHumor is not a trait for women, even less so for women artists in the Italian art world, where women's creativity has historically focused either on intimacy or on abstraction. In order to be taken into consideration by a male-dominated art scene, women artists working in the Italian peninsula have, since the '70s, consistently been obliged to be extremely serious about their work and its content. This trait can be traced all the way to the present with few exceptions, making Goldschmied & Chiari's (Sara Goldschmied and Eleonora Chiari) artistic practice exceptional in its constant employment of a peculiar, irreverent form of humor that functions as subliminal social critique.Humor used as a strategy to reconsider historical events in a post-ideological form of feminism develops in their work in witty installations that articulate a lucid critique of contemporary society and its relationship to history. Radically distancing themselves from the stereotype of authoritative and earnest feminism, Goldschmied & Chiari turn laughter into a metaphor for transformation. Their images trigger subtle political disruptions, allowing them to delve into the complex history of post-Cold War narratives, offering the public a new understanding of the relationships between the symbolic and the social.My first encounter with Goldschmied & Chiari's work (goldiechiari at the time) dates back to 2002 when I was working on a large survey show of emerging Italian art, exIT: Nuove geografie della creatività italiana, curated by Francesco Bonami. I was surprised by their work Senza titolo #17 that portrayed in a full-color photograph two girls dressed as if they were in boarding school, in plaid skirts and colored stockings, with long braids, sitting on the floor helping an elderly "grandmother" knitting in her armchair by making a hank of yarn. Looking closer, one sees that the girls were actually adolescents trapped in a parody that the artists further highlighted by installing in front of the photo what looked like a gigantic ball of yarn but was actually a sphere made of 1,500 cm of barbed wire (Sfera, 2002). The "tableau vivant" quality of the image made it both funny and critical, as visitors could relate as much to the stereotyped enactment of women's domestic roles as to the artists' rebellious desire. Instead of relegating their creativity to the domestic sphere, these "mischievous little girls" had wound a menacing barbed-wire ball that evoked Italy's recent past of social unrest and urban guerrillas. The assumption of ironic activist alter egos in one way referenced feminist practices of the '70s, yet at the same time seemed to mock the violence associated with protest and its success. [End Page 116]This type of atmosphere linked to city barricades and acts of protest is the inspiration for a large... (shrink)

Resumo: O propósito deste artigo é apresentar alguns traços peculiares do Programa de Pós-Graduação em Filosofia em Rede Nacional, o PROF-FILO, com destaque para certas discrepâncias observadas no seu surgimento e para o modo como elas participam no estabelecimento dos contornos que ele adquire e do papel que assume em seus primeiros anos de existência. Conforme veremos, tais discrepâncias, que imprimem claros limites ao novo programa, possibilitam também a ele cumprir um papel peculiar para a consolidação da disciplina de Filosofia (...) no Ensino Médio e, indiretamente, para a Área de Filosofia no país, oferecendo novos elementos para os debates sobre a identidade da Filosofia nas terras tupiniquins. Palavras-chave: PROF-FILO; Mestrado Profissional; Ensino de Filosofia; Formação de Professores PROF-FILO: discrepancies and perspectives of a Professional Master in Philosophy Abstract: The purpose of this article is to present some peculiar traits of the Graduate Program in Philosophy in the National Network, the PROF-FILO, highlighting the discrepancies observed in its emergence and the way they relate to the format it takes on and the role it assumes in its early years of existence. As we will see, such discrepancies that set clear limits to the new program, also allow it to fulfill a peculiar role for the consolidation of the discipline of Philosophy in High School and, indirectly, for the area of Philosophy in the country, offering new elements for the debates. on the identity of Philosophy in Tupiniquin lands.

Come vedremo, queste discrepanze, che danno chiari limiti al nuovo programma, gli permettono anche di svolgere un ruolo peculiare per il consolidamento della disciplina della Filosofia nell'Educazione Secondaria e, indirettamente, per il campo della Filosofia nel Paese, offrendo nuovi elementi per i dibattiti sull'identità della Filosofia in Brasile.

Many different writers have employed what might be termed the ‘existence criterion’ when offering realist analyses of perception. In all these realist accounts, a basic argument may be detected. If any experience—e.g. the having of either a sensory or a mental image—is to be a form of perceiving, then the statement reporting that experience must satisfy a condition which applies to all perceiving-statements. Any putative perceptual statement of the form ‘S perceives x’ must entail a statement to the effect that (...) x, or some y, does exist as a public perceptual object in S’s perceptual range. For example, my statement ‘I see Peter’ will be a proper perceptual statement only if Peter is a public perceptual object now in my line of vision, or only if I take some other public perceptual object now in my line of vision to be Peter. Statements about our having images of things, this basic argument continues, cannot satisfy this condition. The object imaged —e.g. Peter—is not always present in the subject’s perceptual range at the time of the imaging, and the subject does not necessarily take a public perceptual object in his perceptual range to be that object. Hence, any statement reporting our imaging something must be false if it is construed as a report of a perceiving. (shrink)
