Joint TAS and Power Allocation for SDF Relaying M2M Cooperative Networks
Authors: Xu Lingwei , Zhang Hao , Wang Jingjing
Published: April 2016

The outage probability (OP) performance of multiple-relay-based selective decode-and-forward (SDF) relaying mobile-to-mobile (M2M) networks with transmit antenna selection (TAS) overN-Nakagami fading channels is investigated. The exact closed-form expressions for OP of the optimal and suboptimal TAS schemes are derived. The power allocation problem is formulated for performance optimization. Then, the OP performance under different conditions is evaluated through numerical simulations to verify the analysis. The simulation results showed that optimal TAS scheme has a better OP performance than suboptimal TAS scheme. Further, the power allocation parameter has an important influence on the OP performance.

Authors: Ismailov Migdad , Guliyeva Fatima , Nasibov Yusif
Published: April 2016

The concept ofb-frame which is a generalization of the frame in Hilbert spaces generated by the bilinear mapping is considered.b-frame operator is defined; analogues of some well-known results of frame theory are obtained in Hilbert spaces. Conditions for the existence ofb-frame in Hilbert spaces are obtained; the relationship between the definite bounded surjective operator andb-frame is also studied. The concept ofb-orthonormalb-basis is introduced.
Microwave-Assisted Solvent-Free Synthesis of Zeolitic Imidazolate Framework-67
Authors: Zhang Heng , Zhong Jing , Zhou Guoxiang , Wu Junliang , Yang Zhenyu , Shi Xianming
Published: April 2016

A microporous metal-organic framework (MOF), cobalt-based zeolitic imidazolate framework-67 (ZIF-67), was synthesized by the combination of solvent-free hand-mill and microwave irradiation, without any organic solvent and within 30 minutes. The hand-milling process can mix the reactants well by the virtue of high moisture/water absorption capacity of reactants. In addition, the outstanding electromagnetic wave absorption capability of cobalt leads to efficient conversion to MOF structures before carbonization. The obtained ZIF-67 possesses high surface area and micropore volume.

Published: April 2016

Non–muscle-invasive bladder cancer (NMIBC) may progress to muscle-invasive disease, but no effective preventive treatments are available. In addition, no reliable prognostic biomarkers have been identified. We assessed the long-term effect of the oral retinoid fenretinide and the prognostic value of circulating VEGF levels. We updated through the Tumor Registry the vital status of 99 patients with resected Ta/T1 bladder tumors who were recruited in a randomized trial of 2 years of fenretinide or no treatment in 1993–1994. Serum VEGF levels measured at baseline and 12 months were available in a subgroup of 62 patients. After a median of 20.5 years, 54 subjects died, 35 of any cancer and 14 of bladder cancer. Neither overall survival (OS), nor cancer survival (CS) or bladder cancer survival (BCS) was affected by fenretinide (log-rank P ≥ 0.2). DNA aneuploidy in bladder washing was associated with shorter OS (P = 0.02), CS (P = 0.05), and BCS (P = 0.09). Subjects with baseline VEGF levels in the top quintile (≥350 pg/mL) had a significantly shorter OS (P = 0.01), CS (P = 0.02), and BCS (P = 0.008). The trend across quintiles of VEGF was significant for BCS (P = 0.007). Multivariate analyses showed that, in addition to smoking status, VEGF level in the top quintile was an independent prognostic factor for OS (HR = 2.7; 95% CI, 1.1–6.5), CS (HR = 3.3; 95% CI, 1.1–9.4) and BCS (HR = 8.9; 95% CI,1.3–61). Fenretinide did not affect the long-term outcome of patients with NMIBC. High serum VEGF level was a significant predictor of overall and cancer death and may help to identify high-risk subjects who may benefit from a preventive therapy.

Published: April 2016

Background/Aims: To enable the diagnosis of moyamoya disease (MMD), detection of distal internal carotid artery stenosis and hazy network of basal collaterals (BCs) are required. This study aimed at evaluating the factors that could determine the degree of BCs in patients with angiographically confirmed MMD. Methods: We analyzed 146 consecutive patients with MMD (age 26.2 ± 19.6, range 1-75). The degree of BCs (%) was measured based on conventional angiography. Factors associated with the degree of BCs, including clinico-radiological and genetic factors (p.Arg4810Lys variant), were analyzed. Results: The degree of BCs varied among MMD patients and significantly decreased with an increase in the age of diagnosis of MMD (coefficient -1.55; p < 0.001). Although the degree of BC development depends on the MMD stage (Suzuki stage), it is less prominent in adult-onset (>18 years) MMD compared to childhood MMD. The presence of p.Arg4810Lys variant, types of MMD (bilateral vs. unilateral) and stroke (ischemic, hemorrhagic, or asymptomatic), shrinkage (outer diameter) of intracranial vessels, external carotid collateral status, and cortical neovascularization were not associated with the degree of BCs. Conclusion: Although prominent BCs are required for diagnosis of MMD, BCs are decreased with aging, suggesting that angiogenic capacity is altered in adult onset MMD compared to childhood MMD.
Uma investigação sobre os paradigmas da visão a partir de duas versões da Última ceia.
Authors: Bracchi Daniela
Published: April 2016

Seguindo o caminho de duas versões da cena da Última ceia, este artigo busca investigar o paralelismo existente entre a produção de obras visuais que convocam uma maior tatilidade e a adoção de um paradigma sobre a visão diferente do ótico e sem a separação e hierarquização dos sentidos. Propõe-se o paradigma háptico como um aglutinador de conhecimentos e práticas que integram os sentidos e propõem um maior engajamento corpóreo do enunciatário. Nesse contexto, a noção de sinestesia se torna o centro conceitual capaz de explicar essa integração dos sentidos. A partir de tal noção, investiga-se os efeitos de sentido advindos de uma maior tatilidade estimulada visualmente pela obra da Última ceia, de David Lachapelle, analisada ao final do artigo.

O jogo de debreagens na narrativa “O espelho de tinta”
Authors: Cardoso Maurício Moreira
Published: April 2016

O presente artigo contempla o estudo do jogo debreativo no conto “O Espelho de Tinta”, de Jorge Luis Borges. A acenada narrativa insere-se na Escola Literária conhecida como Realismo Fantástico ou Realismo Mágico, que tem o citado autor como um de seus principais expoentes. O jogo debreativo resulta da conjunção dos aspectos componentes da noção debreagem. A debreagem, por seu turno, define-se como a operação através da qual a instância da enunciação disjunge e projeta para além de si certos termos ligados à sua estrutura base, de modo que possa constituir os elementos que servem de fundação ao enunciado-discurso. A debreagem se divide em debreagem actancial (referente à categoria de pessoa), debreagem temporal (referente à categoria de tempo) e debreagem espacial (referente à categoria de espaço). Propusemo-nos fornecer evidências de que o referido jogo contribui para construir certo efeito de sentido de veridicção. Teoricamente (cf. Barros, 2001; Greimas e Courtés ,2008), abraçamos os fundamentos da Semiótica Greimasiana no que diz respeito ao significado de enunciação, enunciador, debreagem. Nossos procedimentos metodológicos consistiram em identificar os elementos debreativos presentes no mencionado conto e analisá-los como geradores de um efeito veridictório. Conclusivamente, pudemos estabelecer uma relação entre os elementos de debreagem presentes na narrativa e o dizer verdadeiro – o efeito veridictório – ali presente, o que nos autoriza a afirmar que o contrato de veridicação se mostrou eficaz em “O Espelho de Tinta”.
Entre exercício e acontecimento - uma leitura do folhetim O estudante de Salamanca.
Authors: Garcia Débora Cristina Ferreira
Published: April 2016

Observar o acontecimento possibilita à semiótica investigar a narrativa como um processo que atinge tanto o sujeito do enunciado como da enunciação do ponto de vista sensível, tornando-se uma ferramenta profícua para reflexões como a que faremos neste artigo, já que nossa intenção é a de verificar como os textos folhetinescos eram produzidos para agirem sobre os leitores do século XIX, mais especificamente, sobre os leitores da seção folhetim do jornal Correio Paulistano. Muitos estudiosos que se dedicaram ao romance-folhetim enumeram diversos procedimentos bastante comuns na produção desse tipo de texto e que apontam para uma certa eficácia do procedimento, dada sua aceitação entre o público para o qual se destinava. Fundamentados nos conceitos desenvolvidos pela semiótica tensiva, mais especificamente acerca do acontecimento e do exercício, faremos uma análise dos primeiros capítulos do folhetim O estudante de Salamanca, publicado no jornal acima referido no ano de 1877, com o intuito de refletirmos sobre a importância da forma de narrar que se apresenta tão ou até mais importante que a história narrada para manter a atenção desses leitores. Veremos que recursos narrativos que produzissem a surpresa e o suspense tinham impacto sobre um dado público leitor a ponto de mantê-lo preso à trama por semanas, meses e até anos a fio. Cabia ao enunciador organizar muito bem esse jogo de revelação e de ocultação de informações para garantir a desejada fidelização dos leitores aos folhetins e, consequentemente, aos periódicos que os publicavam.
O semissimbolismo na propaganda audiovisual: uma análise de Paint.
Authors: Silva Cintia Alves da
Published: April 2016

Este trabalho tem como objetivo analisar o semissimbolismo existente em Paint, um dos comerciais da campanha Colour like no other, lançada pela Sony para a linha de televisores de LCD Bravia, em 2006. Premiado com o leão de ouro em Cannes, em 2007, Paint surpreendeu tanto por sua complexa produção quanto pelos números que confirmaram o seu sucesso: o aumento expressivo nas vendas do televisor e mais de um milhão de acessos ao site do produto. A megaestrutura envolvida na produção de Paint fez com que o público não somente assistisse a propaganda nos veículos midiáticos, mas também buscasse informações sobre como seria – e se seria – possível um espetáculo de tais proporções sem a utilização de recursos de computação gráfica. Assim, com base nos pressupostos da semiótica plástica, especialmente nas contribuições de Jean-Marie Floch para o estudo das relações semissimbólicas, isto é, dos processos de geração de sentido que se dão a partir da homologação entre o plano do conteúdo e o plano da expressão, pretende-se discutir as implicações entre as expressões plástica e musical na composição da propaganda audiovisual, que resultam em efeitos de sentido de verdade e autenticidade, cujo teor persuasivo mostra-se fundamental ao estabelecimento do contrato fiduciário.

Authors: Lamonato Creici , Presser Nadi Helena
Published: April 2016

Delineia as competências profissionais requeridas na execução das tarefas dos trabalhadores que atuam nos meios de hospedagem, por meio da decomposição da classe de comportamentos que determinado cargo demanda. Pesquisa descritiva, coletou dados de 52 vagas de trabalho anunciadas em cinco sites de divulgação de vagas nacionais: Sine, Catho, Indeed, Pense Emprego e Manager. Os dados foram classificados e analisados de acordo com as variáveis dispostas nos anúncios de vagas de empregos analisados. O estudo identificou dez classes de comportamentos, as quais foram traduzidas em diversas classes de comportamentos intermediários dos cargos: comunicar-se com o cliente, relacionar-se com o cliente, agir com proatividade, organizar as atividades, atuar com agilidade, concentrar-se para solução de problemas, trabalhar em equipe, planejar ações, realizar as atividades técnicamente, e liderar com foco para o resultado. Igualmente, no que se refere à escolaridade, o estudo constatou que 73% das vagas do nível operacional e gerencial primam pela absorção de profissionais que possuam no mínimo ensino médio ou superior, porém apenas seis vagas de nível superior solicitam formação na área de Hotelaria, Turismo e Gastronomia. O estudo também apontou que somente 27% das vagas requerem profissionais com domínio de outros idiomas.
Satisfação e Apego ao Lugar: implicações para qualidade de vida em uma visão de marketing de lugares
Authors: Medeiros Fabiana Gama de , Costa Francisco José da
Published: April 2016

Esse estudo busca compreender a relação entre a satisfação ao lugar, o apego ao lugar e a qualidade de vida percebida pelos residentes de um lugar. A análise preliminar dos estudos realizados mostrou que o foco de marketing de lugares tem sido predominantemente voltado para aplicar as ferramentas tradicionais de marketing aos lugares, na busca de atrair visitantes, investidores e novos residentes, com menor ênfase aos agentes residentes dos lugares. Isto justificou o foco deste estudo nos residentes. A partir da revisão da literatura, foi proposto um modelo de relações entre os construtos, testado empiricamente através de modelagem de equações estruturais em amostras de residentes das cidades de João Pessoa, Campina Grande, Guarabira e suas cidades circunvizinhas, no estado da Paraíba. Além do modelo, também testamos e propomos uma escala para medir o construto satisfação com o lugar. Os resultados confirmam as hipóteses e apresentam a satisfação com o lugar e o apego ao lugar como preditores do construto qualidade de vida percebida; uma escala de satisfação com o lugar foi desenvolvida e proposta; e foram identificados os fatores específicos de um lugar que contribuem para a satisfação geral com o lugar.

Relações entre fenomenologia e memória: possíveis reflexões sobre a exclusão social em bibliotecas públicas
Authors: Silva Ana Claudia Perpétuo de Oliveira da
Published: April 2016

O artigo propõe para os bibliotecários, mais precisamente de bibliotecas públicas, uma reflexão sobre a questão da exclusão social. Através da visão de mundo fenomenológica e a extração do componente “memória” neste contexto, objetiva suscitar a reflexão de âmbito filosófica a partir do resgate de pensamentos acerca da exclusão. Ressalta questões relativas à memória como transcendência da “morte” e o acúmulo de conhecimento e, partir deste enfoque, traça possíveis relações com as práticas de bibliotecários, de caráter ético e político, como a exclusão social em bibliotecas públicas.
O modelo de excelência da gestão (MEG) favorece a existência das organizações do conhecimento de Chun W. Choo?
Authors: Garcia Leonardo Guimarães
Published: April 2016

O presente artigo discute se o fato de uma organização utilizar plenamente o Modelo de Excelência da Gestão (MEG) favorece sua transformação no que Choo (2006) denomina “Organização do Conhecimento”. Para tanto, realizou-se um levantamento bibliográfico do qual se extraiu os elementos essenciais do MEG e das organizações do conhecimento de Choo, permitindo assim a comparação entre os modelos. Desse confronto, conclui-se que, em tese, o MEG favorece a existência das organizações do conhecimento, mas que a exploração efetiva dos benefícios oferecidos pelo MEG carece da intervenção de profissionais da informação, por meio de uma gestão da informação que compatibilize as demandas organizacionais às especificidades do modelo de Choo.

Por um dicionário bilíngue pedagógico para a leitura em língua estrangeira
Authors: Loguercio Sandra Dias
Published: April 2016

Este trabalho reflete sobre a natureza da informação lexicográfica dos dicionários bilíngues e seu uso para atividades de leitura-compreensão por um público não proficiente na língua de recepção, propondo, a partir daí, um dicionário bilíngue pedagógico para a leitura em língua estrangeira. Por se tratar de leitores cuja experiência de estudo dessa língua é bastante limitada, exigindo de sua parte uma autonomia precoce de aprendizagem, esse dicionário deve reunir as funções comunicativa, fornecendo a informação buscada na situação de leitura, e cognitiva, favorecendo a aprendizagem de saberes lexicais e gramaticais que incidam na competência leitora. Para isso, é proposta uma reformulação de sua microestrutura que passa pelo tratamento da unidade lexical, do modo de criação referencial, contextual e por uma organização hipertextual, elementos ilustrados aqui através do par de línguas francês-português.
In Pulmonary Arterial Hypertension, Reduced BMPR2 Promotes Endothelial-to-Mesenchymal Transition via HMGA1 and Its Target Slug

Published: April 2016

Background—

We previously reported high-throughput RNA sequencing analyses that identified heightened expression of the chromatin architectural factor High Mobility Group AT-hook 1 (HMGA1) in pulmonary arterial endothelial cells (PAECs) from patients who had idiopathic pulmonary arterial hypertension (PAH) in comparison with controls. Because HMGA1 promotes epithelial-to-mesenchymal transition in cancer, we hypothesized that increased HMGA1 could induce transition of PAECs to a smooth muscle (SM)–like mesenchymal phenotype (endothelial-to-mesenchymal transition), explaining both dysregulation of PAEC function and possible cellular contribution to the occlusive remodeling that characterizes advanced idiopathic PAH.

Methods and Results—

We documented increased HMGA1 in PAECs cultured from idiopathic PAH versus donor control lungs. Confocal microscopy of lung explants localized the increase in HMGA1 consistently to pulmonary arterial endothelium, and identified many cells double-positive for HMGA1 and SM22α in occlusive and plexogenic lesions. Because decreased expression and function of bone morphogenetic protein receptor 2 (BMPR2) is observed in PAH, we reduced BMPR2 by small interfering RNA in control PAECs and documented an increase in HMGA1 protein. Consistent with transition of PAECs by HMGA1, we detected reduced platelet endothelial cell adhesion molecule 1 (CD31) and increased endothelial-to-mesenchymal transition markers, αSM actin, SM22α, calponin, phospho-vimentin, and Slug. The transition was associated with spindle SM-like morphology, and the increase in αSM actin was largely reversed by joint knockdown of BMPR2 and HMGA1 or Slug. Pulmonary endothelial cells from mice with endothelial cell–specific loss of
Bmpr2
showed similar gene and protein changes.

Conclusions—

Increased HMGA1 in PAECs resulting from dysfunctional BMPR2 signaling can transition endothelium to SM-like cells associated with PAH.
Development and Characterization of an Inducible Rat Model of Chronic Thromboembolic Pulmonary Hypertension
Authors: Arias-Loza Paula-Anahi , Jung Pius , Abeßer Marco , Umbenhauer Sandra , Williams Tatjana , Frantz Stefan , Schuh Kai , Pelzer Theo
Published: April 2016

Chronic thromboembolic pulmonary hypertension (CTEPH) is an entity of PH that not only limits patients quality of life but also causes significant morbidity and mortality. The treatment of choice is pulmonary endarterectomy. However numerous patients do not qualify for pulmonary endarterectomy or present with residual vasculopathy post pulmonary endarterectomy and require specific vasodilator treatment. Currently, there is no available specific small animal model of CTEPH that could serve as tool to identify targetable molecular pathways and to test new treatment options. Thus, we generated and standardized a rat model that not only resembles functional and histological features of CTEPH but also emulates thrombi fibrosis. The pulmonary embolism protocol consisted of 3 sequential tail vein injections of fibrinogen/collagen-covered polystyrene microspheres combined with thrombin and administered to 10-week-old male Wistar rats. After the third embolism, rats developed characteristic features of CTEPH including elevated right ventricular systolic pressure, right ventricular cardiomyocyte hypertrophy, pulmonary artery remodeling, increased serum brain natriuretic peptide levels, thrombi fibrosis, and formation of pulmonary cellular-fibrotic lesions. The current animal model seems suitable for detailed study of CTEPH pathophysiology and permits preclinical testing of new pharmacological therapies against CTEPH.
Disposable Music
Authors: Hajdu Georg
Published: April 2016

This article introduces the concept of real-time composition and composition as a “dispositif” in the sense of Foucault and Deleuze, defining it as a heterogeneous ensemble of pieces that together form an apparatus. The introduction situates the dispositif in the context of cultural developments, most notably its slow but steady shift away from textualization in digital media. As musicians are adapting to ensuing cultural and, above all, economic changes, new musical forms emerge that rely to a lesser degree on fully notated scores, such as “comprovisation” or laptop performance. Antithetically, the computer also allows the creation of “authorless” notated scores in real time to be sight-read by capable musicians—a practice for which special software has been developed in recent years. Because these scores are not meant to be kept and distributed, they are ephemeral and, therefore, disposable. Three examples by the author are given to illustrate the interwovenness of this approach, where carefully selected narratives and dramaturgies make up for the inherent unpredictability of the outcome.
Generative Audio Systems Using Power-Preserving All-Pass Filters
Authors: Surges Greg , Smyth Tamara , Puckette Miller
Published: April 2016

This article describes the use of second-order all-pass filters as components in a feedback network, with parameters made time varying to enable effects such as phase distortion in a generative audio system. The term “audio” is used here to distinguish from generative “music” systems, emphasizing the strong coupling between processes governing the production of high-level music and lower-level audio. The classical time-invariant implementation of an all-pass filter is subject to issues of instability that can arise when time-invariant filter parameters are allowed to vary over time. These instabilities are examined, along with the adoption of a power-preserving rotation matrix formulation of the all-pass filter to ensure stability and ultimately an improved synthesis for a generative audio system.
The Vienna Method in Amsterdam: Peter Alma's Office for Pictorial Statistics
Authors: Benus Benjamin , Jansen Wim
Published: April 2016

Over the course of the 1930s, the Dutch artist and designer, Peter Alma, produced an extensive body of information graphics. Working for a wide variety of corporate clients seeking to provide social and economic information to general audiences, Alma was one of the principal Dutch practitioners and promoters of the approach to information design known as the “Vienna Method of Pictorial Statistics,” initially developed by the social scientist Otto Neurath and the graphic artist Gerd Arntz. In addition to providing an account of Alma's role in the further development and dissemination of this method, this essay assesses the nature of Alma's contribution to the field of visual education and considers the place of his pictorial statistics production within his broader artistic oeuvre.
Material Semiotics of Form Giving: The Case of the Electric Turkish Coffee Pot
Authors: Kaygan Harun
Published: April 2016

The article discusses material semiotics as a valuable framework for the analysis of design processes, and focuses on form giving practices. For this purpose, the design processes of electric Turkish coffee pots are studied through interviews and document analyses. It is argued that neither form giving nor product form can be considered to be singular or stable throughout a design process, and that semantic and material relations that are built and maintained around the product form need to be traced for a fuller understanding.
Digesting djd 12: Its Contribution to the Textual Criticism of the Pentateuch
Authors: Rofé Alexander
Published: April 2016

The contribution of the fragmentary scrolls of Genesis-Numbers to the history of the biblical text lies in both primary and secondary readings. The former consist of variants to Gen 22:14; Exod 1:5; 39:21; Lev 26:30–31; Num 32:30. The latter are extant in Exod 2:3; Lev 1:1–7; 17:4; Num 18:26; 20:13 and chapters 27 + 36. The secondary readings are instructive concerning the transmission of the biblical text during the Second Commonwealth. They derived from ideological motives or literary concerns.
A “Chariot of Fire” in Amos 7:4: A Text Critical Solution for qōrē’ lārīb bā’ēš
Authors: Simone Michael R.
Published: April 2016

mt Amos 7:4 has a number of difficulties, one of which is the phrase qōrē’ lārīb bā’ēš. Although all ancient versions agree in some way with the Hebrew, differences among them reveal the difficulty that ancient scholars encountered when interpreting the phrase. The difficult Hebrew and the multiple ancient versions together have led many modern scholars to attempt an emendation. The textual corrections suggested by Hendrik Elhorst and Delbert Hillers appear in important English biblical translations, but both are problematic. This study suggests the emendation qōrē’ lǝrekeb ’ēš as a solution to the crux. The initial error was caused by misdivision of words coupled with bet-kaf confusion. Unlike the other suggestions, this correction has three strengths to recommend it: the error was simple, the corrected words appear elsewhere in Hebrew, and the image of a fiery divine chariot has counterparts in cognate ancient Near Eastern literature.
Bin ich Hüter meines Bruders?
Authors: Bae Hee-Sook
Published: April 2016

The reason underlying God’s divergent actions towards the offerings of Cain and Abel has been highly disputed. It has been often assumed that the reason mainly lies in the two offerers’ differing dispositions and attitudes or in the quality and character of their offerings. However, the close relationship between YHWH and Cain and the differences between the text’s descriptions of Cain and of Abel provide a more concrete rationale for God’s action: Through the seemingly unjust rejection of Cain’s offering, YHWH calls on him to recognize his relationship and responsibility for his inferior brother. That the relation to others is inseparable from the relation to God becomes evident once more in the punishment.
Πάντα πράττειν. SOCRATE E IL BENE NELLA REPUBBLICA
Authors: FERBER RAFAEL
Published: April 2016

In this I draw attention to the strangeness (atopia) that Plato’s Republic has not only for Plato’s contemporaries, but also for us. This strangeness for us consists of the fact that Plato’s Republic does not allow for a plurality of philosophical opinions, but enforces one true philosophy (philosophia alêthê) or one conception of the Good to all citizens. The platonic Republic describes not only a state, but also a kind of pre-Christian church. Second, I emphasize that the Socratic principle in which every soul does everything for the Good (panta prattei) can be translated in two ways: Every soul does everything for the sake of the Good, or goes to all lengths for the sake of the Good. Depending on the different translations, we have a different picture of the platonic Socrates in the Republic, an intellectualiste Socrates for whom irrational desires do not exist, or a Socrates who also accepts irrational desires. Third, I discuss the laughter after Socrates’ claim that the Good is even “beyond being”. Who here is laughing about whom, Glaucon about Socrates, or Socrates about Glaucon, or perhaps Plato about himself?
SENOFANE FRA I SOFISTI. DAI LIMITI DELLA CONOSCENZA (21B34 DK) AL PARADOSSO ERISTICO (PLAT. MEN. 80D5-E5)
Authors: SASSI MARIA MICHELA
Published: April 2016

I argue in this paper that the formulation of the eristic paradox in Plato’s Meno (80d5-e5) echoes Xenophanes’ Frg. 34, by drawing attention to a number of significant similarities of expression and to equally significant points of theoretical tension between the two texts. Bringing into focus such further authors as Protagoras, Gorgias, and Metrodorus of Chius, I claim that Xenophanes’ epistemological option was central to the philosophical debate in the Sophistic milieu, and that here started a “pre-skeptical” reading of Frg. 34, which was to affect Plato’s.

Anaxagoras brought to Athens the hope that becoming, despite the tradition of the Eleatic school, might still be intelligible, not only because he sees it as the effect of an order crafted by a divine mind, but also because he opposes the Parmenidean claim that there is no point in trying to know the ϕύσις (i.e. essence) of things that need to grow (ϕύεσθαι). Anaxagoras finds in the growth (ϕύεσθαι) of vegetais a principle of identity that makes becoming intelligible. Using parts of animals to which ancient Greek also applies the same verb (we grow flesh, nails and hair), Anaxagoras extends the consistency of vegetal becoming to all beings, all of them now coming from seeds. The essence (ϕύσις) of things, can now be explained through its origins -that from which it grows (ϕύεσθαι). The new philosophical fifth century meaning of ϕύσις, as origin, could have stemmed from such a new impulse to inquire about the seeds of all things.
CRATYLE ET LA RÉCEPTION D’HÉRACLITE À ATHÈNES
Authors: PONCHON PIERRE
Published: April 2016

The « problem of Cratylus » consists in the difficulty of combining his two main theseis, that is the universal flow and the natural rectitude of nouns. Aim of this paper is to show that this evolution can be recomposed more precisely than it used to be. The first step of Cratylus’ thought is an etymological and lexical attempt to find the logos contained in the noun, which expresses its true nature, following a method already used by Heraclitus. Considering the deficiencies of this solution, and particularly the problem of the fixity of the meaning of nouns by comparison with verbs which indicate a movement, Cratylus explorated a syntactical way to mould the flow of the reality into the flow of the language itself. This peculiar language is based on the use of neutral present participles. But once again some difficulties, maybe derived from the consideration of Eleatic arguments on the impossibility for language, as runnig after thing, to move and change as fast as the reality does, force Cratylus to leave out this project. This respect for the Heraclitean flow leads him to modify in a more radical sense the Heraclitus’ river flow formula and to search refuge in silence. The evolution of Cratylus, hence, would testify to the presence in Athens of an Heraclitean circle, which is not impermeable to the arguments of the Eleatic followers and which contributes both to reduce the doctrine of Heraclitus to the theory of flow and to contrast it with that of Parmenides and Zeno.
LA “DOTTRINA RISERVATA” DI PROTAGORA (PLAT. THEAET. 152c7-E1)
Authors: BRANCACCI ALDO
Published: April 2016

In modern studies it has been largely denied that the so-called “secret doctrine” (which would be more correct to call “private teaching”) of the Theaetetus can be traced back to Protagoras. However, reasons why this doctrine can not be his own, have never been explained. At the same time, an appropriate justification of the hypothesis that it would be considered a pure Platonic creation has never been offered, nor was explained why it would be attributed to followers of Protagoras, but not to Protagoras himself. This article examines the Platonic text in an analytical way, shows how Plato repeatedly attributes to the sophist of Abdera the content of this doctrine, and, based on fragments of Protagoras and other doctrines related to him by ancient sources, it is evident that nothing in Protagorean concepts comes into conflict with Theaetetus so-called “secret doctrine”, and how actually is completely coherent with it.
NI EL HOMBRE ES BLANCO NI EL CABALLO CORRE. ARGUMENTOS ANTIPLATÓNICOS EN ESTILPÓN DE MÉGARA
Authors: MÁRSICO CLAUDIA
Published: April 2016

The testimonies of Stilpo of Megara show an anti-Platonic position within the megaric program against fundationists attempts. This paper studies a particular point of this deployment. We will review the origin of the views that locate thruth on the onomastic or on the predicative level. This initial survey will provide the basis for the study of the paradoxes of the nomination, an element Stilpo used as a tool to challenge the theory of Forms, and the analysis of the aporias of predication, through which he rejects the combination of parts of the sentence in order to represent reality. The figure of Stilpo reveals the dialogical context in which ancient philosophies developed and, at the same time, displays ways of thinking the relationship between language and reality often forgotten.
EL ENCOMIO DE HELENA Y LA RESPONSABILIDAD MORAL
Authors: ECHEÑIQUE JAVIER
Published: April 2016

In his Encomium of Helen, Gorgias provides us with a variety of arguments in order to show that Helen was not to be held accountable for having eloped with Paris. The main thesis advanced in this article is that these arguments, despite their apparent diversity, are given a unitary structure by the concept of force, and by the analogy that Gorgias estalishes between persuasion, the emotions, and sense-perception on the one hand, and this concept on the other. If this argument is successful, it shows that practically none of our actions are such that we are morally responsible for them. I discuss the cogency of this argument in connection with Aristotle’s objections to it.
IL BELLO NEL SIMPOSIO: SOGNO 0 VISIONE?
Authors: GONZALEZ FRANCISCO J.
Published: April 2016

What is often identified with Plato’s doctrine of love is greatly complicated, if not even compromised, by the dialogical form in which it is presented. In the first place, this account of love in placed in the mouth of a character, Diotima, who as priestess and woman seeking to initiate Socrates into mysteries he may not be able to follow is sharply distinguished from the philosopher. Furthermore, even the ideal portrait of the philosopher we find in the character of Socrates is rendered suspect by the fanaticism and erotic idolatry of those who narrate the dialogue, Apollodorus and Aristodemus. When these narrative complications are taken into account, what emerges is a tension between the mortal knowledge of the philosopher, continually demanding to be reborn by its continual retreat into oblivion, and that secure knowledge and possession of divine reality that the philosopher can only dream of.
PARMÉNIDES CIENTÍFICO Y LAS OPINIONES DE LOS MORTALES (APUNTES PARA UNA NUEVA INTERPRETACIÓN)
Authors: BREDLOW LUIS ANDRÉS
Published: April 2016

The aim of this paper is to suggest a possible way of understanding Parmenides' so-called doxa, starting from the clear and lucid formulation of the problem which is offered to us in some recent writings of N.-L. Cordero. We agree with Cordero (and some others) on the need to distinguish between the "opinions of mortals" and Parmenides' own physical theories, usually confused under the label of the doxa or "way of opinion" (I-II); not so with his proposal to insert the 'scientific' fragments into the discourse on Truth, which seems rather incompatible with the sources (III) and ultimately grounded on the confusion –shared by most interpreters– of the ordering of the parts of the Poem, enounced at the end of fr. 1 (IV), with the "ways of inquiry" of frs. 2 and 6-7 (V). This is followed by an outline of a tentative reconstruction of Parmenides' polemics against the beliefs of mortals (VI-VIII). The guiding principle of Parmenides' physics is the mixture and interpenetration of the apparent opposites separated by mortals (VI), beginning with the antithesis 'light' / 'darkness', i. e. 'life' / 'death', the dominions of Zeus and of Hades in the traditional world vision which is refuted by the new cosmology of Parmenides (VII). But even so, the new cosmos is in its own way a "deceptive order" as well: since what-is is continuous and homogeneous, the entities postulated by the physical theory have to be necessarily fictitious or conventional; only the explicit acknowledgement of this status prevents the theory from the error of mortals, which consists in taking linguistic convention for the true being of things (VIII).
NOUS AND AISTHĒSIS: TWO COGNITIVE FACULTIES IN ARISTOTLE
Authors: RENERO ADRIANA
Published: April 2016

In disagreement with Claudia Baracchi's controversial thesis that there is a 'simultaneity and indissolubility' if not an 'identity' of intelligence (nous) and perception (aisthēsis) at the core of Aristotle's philosophy, I will argue that Aristotle maintains a fundamental distinction between these cognitive faculties. My goal in this paper is to examine specific parts of two central and complex passages, VI.8, 1142al2-30 and VI. 11, 1143a33-bl5, from the Nicomachean Ethics to show that Baracchi's view is unpersuasive. I will show that Aristotle considers nous to be a different capacity than mere perception and one through which particulars and indemonstrable principles become intelligible. Moreover, I will show that Aristotle considers that the objects of nous differ in kind from those that sensation (our senses) and perception (inference from our senses) grasp. After examining critically Baracchi's thesis in light of a close reading of those two relevant passages, I will conclude the paper by showing the significance of Aristotle's claim that a state is defined in terms of its objects of apprehension for understanding the distinction between nous and aisthēsis.
THE ROLE OF GRACE IN ARISTOTLE'S THEORY OF EXCHANGE
Authors: GALLAGHER ROBERT L.
Published: April 2016

Aristotle's unusual view that charis should play a role in exchange is defended from the criticisms of Meikle and others. Aristotle proposes to amend the conventional Athenian status transaction so that it benefits the weaker party. The stronger is rewarded with honour and increased social influence, which could protect him/her from punitive taxation or court judgments. The relations between Aristotle's views and those of Polanyi are indicated.
Articoli: ALHΘEIA LOGICA, ALHΘEIA ONTOLOGICA IN PLATONE
Authors: CENTRONE BRUNO
Published: April 2016

My paper aims to analyse the Platonic conception of ontological ὰλήθεια and verify whether or not this conception depends on the etymological origin of the Greek word as a derivative noun from λανθάνειν. I shall start my inquiry by referring to Heidegger’s philosophical characterisation of ὰλήθεια as Unverborgenheit, and move on to quote relevant passages from the Homeric poems. I shall try to demonstrate – through the evidence from some key-passages of the Republic, the Phaedo, the Phaedrus and the Philebus – that, even if we can find an ontological conception of the truth in Plato, this does not depend on the Greek etymology of ὰλήθεια, but rather on the archaic correspondance between being and thought.

The known morphological features in identifying common species of foliose Bangiales (e.g., members of Pyropia and Porphyra), which are very few and often overlapping, are recently resolved using comparative analysis of DNA sequences and statistics.  Records of foliose Bangiales in the Philippines were historically identified based on morphology. Considering the recent radical changes in the taxonomy among these rhodophytes and problems posed by morphology-based identification, taxonomic re-appraisal of Philippine foliose Bangiales based on critical morphological and molecular studies is needed.  This study used plastid rbcL and mitochondrial COI-5P gene sequences to investigate the identity of foliose Bangiales collected in Palaui Is., Sta. Ana, Cagayan, Philippines. Observation of key phenotypes revealed the identity of the collected materials as Py. tanegashimensis. Resulting phylogenetic trees showed placement of our collected specimens into a highly supported Py. tanegashimensis clade from Japan and Brazil. Our molecular analysis also suggested that the Philippine Py. tanegashimensis includes endemic populations distinct from the introduced strain originally reported from Brazil.
Rediscovery, typification, and conservation assessment of Saranthe ustulata (Marantaceae)
Authors: FUNEZ LUÍS ADRIANO , HASSEMER GUSTAVO , TREVISAN RAFAEL
Published: April 2016

Saranthe ustulata was described by Otto Georg Petersen in 1890 based on undated material collected by Johann Friedrich Theodor Müller in southern Brazil during the nineteenth century. Since then, absolutely no information was available about this species, and it has even recently been thought as probably extinct. More than a century later, we discovered in the “Railroad of Bromeliads” (Apiúna municipality, Santa Catarina state, Brazil) a population of S. ustulata. A detailed description of this species is provided and its conservation status is assessed. Furthermore, we designed a lectotype and an epitype for this name. Our results reinforce the urgent need of more taxonomic research both in tropical regions, and in older herbaria, where a multitude of new species still await discovery and description.
Revision of the family Nothybidae (Diptera: Schizophora)
Authors: LONSDALE O. , MARSHALL S.A.
Published: April 2016

The family Nothybidae (Diptera: Schizophora) is revised. The family consists of 11 species in the single genus Nothybus Rondani, which occurs in Papua New Guinea, Nepal and much of the Oriental Region. Three species are described as new: N. absens spec. nov. (China), N. cataractus spec. nov. (Laos, Thailand) and N. procerus spec. nov. (India). Nothybus longithorax Rondani, 1875 is treated as a junior synonym of N. longicollis (Walker, 1856). Nothybus decorus Meijere, 1924 syn. nov. is included as a junior synonym of N. lineifer Enderlein, 1922.
