Este volume resume as palestras apresentadas durante o simpósio comemorativo dos "100 Anos da Física Quântica", realizado no Instituto de Física da USP. Para avaliar o significado dessa comemoração, basta lembrar que a Física no século XIX parecia estar completa. Os textos agrupados neste volume tratam de aspectos históricos associados à emergência inicial da teoria quântica, de desenvolvimentos relacionados com algumas das suas mais notórias conseqüências, e de aplicações abrangendo fenômenos desde a escala sub-atômica, atômica e molecular, até as dimensões (...) do universo como um todo.

A partire dalla metà del Novecento, dopo una modernità dominata da prospettive di stampo deontologistico o utilitaristico, la filosofia pratica contemporanea ha visto il sorgere di una ripresa di interesse per un’etica “in prima persona”, in grado di offrire una prospettiva integrale sul soggetto e centrata sullo sviluppo del suo carattere e della sua personalità; in breve, si è assistito a un nuovo potente ingresso in scena dell’idea del bene, e, con essa, della virtù quale via maestra per conseguire il (...) fine adeguato della vita umana. Il volume si propone di rendere conto – anche in correlazione al ruolo delle emozioni, ma non solo – del percorso filosofico della virtù: dall’indagine delle sue fonti “classiche”, all’inizio del suo declino nella modernità, al risorgere della sua vitalità negli ultimi decenni nelle diverse aree linguistico-culturali, tenendo anche conto delle differenti discipline con cui si è interfacciata. Esso non pretende di esaurire i percorsi e le suggestioni che una tematica così vasta presenta, né di coprirne tutta la storia; piuttosto, vuole rappresentare uno stimolo alla ricerca, ponendo in connessione tagli disciplinari e metodologici differenti per offrire una riflessione a tutto campo, che metta in dialogo studiosi provenienti da ambiti diversi ed apra nuove prospettive.Saggi di: Francesco Camera, Angelo Campodonico, Elisabetta Cattanei, Michel Croce, Elisa Cuttini, Marco Damonte, Elisa Grimi, Simona Langella, Alberto Masala, Alma Massaro, Letterio Mauro, Giacomo Samek Lodovici, Maria Silvia Vaccarezza, Paolo Vignola, Lodovica Maria Zanet, Matteo Zoppi.

La antropología filosófica de L. Wittgenstein está siendo discutida intensamente desde diferentes puntos de vista. El libro reflexiona alrededor de la propuesta de P. M. S. Hacker de su trabajo ‘El enfoque antropológico y etnológico de Wittgenstein’. El autor se interroga si cuando adoptamos una visión antropológica ubicamos nuestra posición externamente, para ver las cosas objetivamente. Para ello, se analiza el problema vinculado a la gramática y su constitución conceptual. Plantea hasta que punto compartimos los conceptos que usamos en nuestro (...) enfoque antropológico. V. Sanfélix entiende que L. Wittgenstein ha ido desarrollando un historicismo sin historia y una etnología sin etnografía e indica que la utilidad de esta “etnología fantástica” ayuda a ganar una visión sinóptica de la gramática de nuestros conceptos. A. Tomasini Bassols reflexiona alrededor la plataforma sobre la que elabora la antropología filosófica y si se puede sostenerse que la obra de Wittgenstein contiene una antropología filosófica. L. Hertzberg examina el modo como Hacker analiza los conceptos. Repasa la distinción “analítico/sintético” y el “historicismo sin historia”. M. Holguín razona acerca de la “historia natural”. Desde su punto de vista, Hacker justifica los calificativos de aproximación “antropológica” o “etnológica” con el fin de describir una nueva perspectiva que le permite abordar los problemas conceptuales. W. Jacorzynski reconsidera el enfoque etnológico de Wittgenstein y se para a considerar el análisis conductual, la regularidad/uniformidad, la historicidad (“sin historia”), la autonomía y la arbitrariedad de la gramática. J. Sádaba profundiza acerca del esquema general desde donde se interpreta nuestra actividad existencial sin que por ello se proponga describir historiográficamente los recorridos de la humanidad. J. Padilla Gálvez ubica el programa antropológico en una fenomenología epistemológica que se caracteriza por el estudio del análisis del lenguaje usado y conjetura que el proyecto fenomenológico quedaría corto si analiza exclusivamente la gramática ya que esta carece de perspicuidad. Por esta razón, el programa requiere de un análisis amplio cuyo proyecto se complemente con la “representación perspicua”. (shrink)

En este artículo, examino algunas características importantes de las teorías de conciencia y autoconciencia de Brentano y Rosenthal. En particular, analizo la distinción entre estados mentales y estados conscientes, y la cuestión relacionada con de determinar si todos los estados mentales pueden convertirse en estados conscientes. Interpreto la teoría de Brentano como una teoría de la mente de un nivel que está de acuerdo con la fusión cartesiana entre los estados mentales y la conciencia. Argumento que los problemas que surgen (...) de la posición de Brentano son, hasta cierto punto, superados por una teoría de orden superior, de modo que la posición de Rosenthal es más precisa. Sin embargo, estoy en desacuerdo con ambos en la interpretación de la consciencia de un estado mental como autoconciencia. Desarrollo los fundamentos de una teoría basada en la primacía del organismo y su mundo vital, y de la experiencia consciente como la forma superior de la vida mental, que tiene, sin embargo, sus raíces en la compleja red de estados mentales que son no estados conscientes.In this paper, I examine some important features of Brentano’s and Rosenthal’s theories of consciousness and self-consciousness. In particular, I discuss the distinction between mental states and conscious states, and the related question of determining whether all mental states can become conscious states. I interpret Brentano’s theory as a one-level theory of mind which is in keeping with the Cartesian conflation between mental states and conscious-ness. I argue that the problems arising from Brentano’s position are to a certain extent surpassed by a higher-order theory, so that Rosenthal’s position is more accurate. Nevertheless, I disagree with both in the construal of the consciousness of a mental state as self-consciousness. I develop then the fundamentals for a theory based on the primacy of the organism and its vital world, and of conscious experience as the higher form of mental life, which has, however, its roots in the complex net of mental states which are not conscious states.

Speaker recognition under mismatched conditions is a challenging task. Speech signal is nonlinear and nonstationary, and therefore, difficult to analyze under realistic conditions. Also, in real conditions, the nature of the noise present in speech data is not known a priori. In such cases, the performance of speaker identification or speaker verification degrades considerably under realistic conditions. Any SR system uses a voice activity detector as the front-end subsystem of the whole system. The performance of most VADs deteriorates at the (...) front end of the SR task or system under degraded conditions or in realistic conditions where noise plays a major role. Recently, speech data analysis and processing using Norden E. Huang’s empirical mode decomposition combined with Hilbert transform, commonly referred to as Hilbert–Huang transform, has become an emerging trend. EMD is an a posteriori, adaptive, data analysis tool used in time domain that is widely accepted by the research community. Recently, speech data analysis and speech data processing for speech recognition and SR tasks using EMD have been increasing. EMD-based VAD has become an important adaptive subsystem of the SR system that mostly mitigates the effect of mismatch between the training and the testing phase. Recently, we have developed a VAD algorithm using a zero-frequency filter-assisted peaking resonator and EMD. In this article, the efficacy of an EMD-based VAD algorithm is studied at the front end of a text-independent language-independent SI task for the speaker’s data collected in three languages at five different places, such as home, street, laboratory, college campus, and restaurant, under realistic conditions using EDIROL-R09 HR, a 24-bit wav/mp3 recorder. The performance of this proposed SI task is compared against the traditional energy-based VAD in terms of percentage identification rate. In both cases, widely accepted Mel frequency cepstral coefficients are computed by employing frame processing from the extracted voiced speech regions using the respective VAD techniques from the realistic speech utterances, and are used as a feature vector for speaker modeling using popular Gaussian mixture models. The experimental results showed that the proposed SI task with the VAD algorithm using ZFFPR and EMD at its front end performs better than the SI task with short-term energy-based VAD when used at its front end, and is somewhat encouraging.

Unamuno’nun Sis adlı romanı gerçekliğin doğasına ilişkin felsefi bir sorgulama edimini bir aşk hikâyesi etrafında sembolize ederek dolaylı bir biçimde okuyucuya sunmaktadır. Eserin kahramanı Augusto Pérez’in varoluşsal krizinin kurgu ve gerçeklik arasındaki ilişkiyle birlikte farklı bir boyuta taşındığı bu roman, hayatın anlamı, ölümsüzlük arzusu ve bireyin tanrıyla olan ilişkisi gibi temaları varoluş ve kimlik arayışı ekseni etrafında şekillendirerek tartışmaya açmaktadır. Nesnel gerçeklik ve öznel hakikat arasında gidip gelen bu tartışma, Unamuno’nun varoluşçuluğu hakkında önemli ipuçları taşımakta ve kavramsal kişilikler aracılığıyla ustaca (...) ortaya koyduğu diyalog yöntemini dâhiyane edebi üslubuyla birleştirmektedir. Hayatın muğlaklıklarla dolu belirsiz bir yapısı olduğunu ifade eden Unamuno için yaşamın kendisi bir sistir. Dahası, yaşamın tüm canlılığının ve dinamikliğinin taşıyıcısı olan bu sisi aklın ve mantığın ışığında dağıtmaya ve berraklaştırmaya çalışmanın kendisinin komik olduğunu belirten Unamuno, yaşamın anlamının tam da bu trajik anlamı içinde ortaya çıktığını iddia eder. Aklın bildikleri ile kalbin inandıkları arasında insan absürt ve paradoksal olana adeta Kierkegaardcı bir iman sıçramasıyla bağlanmalıdır. Unamuno’nun varoluşçuluğunu gerçeklik problemi bağlamında değerlendirmeye çalışan bu makalenin amacı, varoluşun kurgu ve gerçeklik arasındaki özel yerini öznel bir iç hesaplaşmaya dönüştürme gerekliliğine dikkat çekmektir.

Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing photon budget during the epoch of reionization, but their escaping photons cannot be detected directly due to inter-galactic medium opacity. Hence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum photon leakage up to z 4 to (...) define indirect indicators allowing analogues to be found at the highest redshift. Aims. Long gamma-ray bursts explode typically in star-forming regions of faint, star-forming galaxies. Through LGRB afterglow spectroscopy it is possible to detect directly LyC photons. Our aim is to use LGRBs as tools to study LyC leakage from faint, star-forming galaxies at high redshift. Methods. Here we present the observations of LyC emission in the afterglow spectra of GRB 191004B at z = 3:5055, together with those of the other two previously known LyC-emitting LGRB, to determine their LyC escape fraction and compare their properties. Results. From the afterglow spectrum of GRB 191004B we determine a neutral hydrogen column density at the LGRB redshift of og =17:2 0:15, and negligible extinction. The only metal absorption lines detected are C iv and Si iv. In contrast to GRB 050908 and GRB 060607A, the host galaxy of GRB 191004B displays significant Ly emission. From its Ly emission and the non-detection of Balmer emission lines we constrain its star-formation rate to 1 SFR 4:7 M yr. 1. We fit the Ly emission with a shell model and find parameters values consistent with the observed ones. The absolute LyC escape fractions we find for GRB 191004B, GRB 050908 and GRB 060607A are of 0:35+0:10.0:11, 0:08+0:05.0:04 and :20+0:05.0:05, respectively. We compare the LyC escape fraction of LGRBs to the values of other LyC emitters found from the literature, showing that LGRB afterglows can be powerful tools to study LyC escape for faint high-redshift star-forming galaxies. Indeed we could push LyC leakage studies to much higher absolute magnitudes. The host galaxies of the three LGRB presented here have all M1600 >.19:5 mag, with the GRB 060607A host at M1600 >.16 mag. LGRB hosts may therefore be particularly suitable for exploring the ionizing escape fraction in galaxies that are too faint or distant for conventional techniques. Furthermore the time investment is very small compared to galaxy studies. (shrink)

The sphere of manifestation of philosophy is thinking. Thinking itself appears and is reflected in different forms, which contributes to a different perception of philosophy. The study and teaching of philosophy as a science is its main direction, an important condition for which is the disclosure of truth. Throughout history, this process manifested itself first as a manifestation of philosophy in theology, and then as its reflection in poetry. "Philosophy of Azerbaijani Studies" by Heydar Aliyev is a discourse aimed at (...) the formation and development of society. In other words, the national leader directed philosophy to its practical implementation in statehood and human life. According to our conclusions, Heydar Aliyev's "philosophy of Azerbaijani studies" was not only an intention, but also a means. The basis of this philosophy was laid in advance, but its full formation took place during the period of independence of Azerbaijan. The main tasks in this situation were self-consciousness, self-return and self-expression. The basis of the essence of the “philosophy of Azerbaijani studies” is, regardless of the affiliation and dissent of the people, to preserve and maintain the main traditions and cultural heritage. It is precisely such efforts that ensure the ideological security of society and actually prevent the creation of problems and barriers that block its development. Heydar Aliyev combined various understandings of globalization, multiculturalism and cosmopolitanism in a single understanding and reunited them in a common philosophy, which was called the “philosophy of Azerbaijani studies”. In his reports and speeches, explaining the essence of the "philosophy of Azerbaijani studies", he referred to a single whole of different cultures and noted the importance of solitude. The strategic plan and the main elements of the “philosophy of Azerbaijani studies” are the development of the Azerbaijani language, religion and culture, as well as the preservation of national and spiritual values and traditions. In the article, all these concepts are explained with illustrative examples. In integrity, Heydar Aliyev's "philosophy of Azerbaijani studies" serves to unite, preserve, develop the tradition of independence and create a legal-social state. (shrink)

Laudato si’, with its articulation of a familial ecology reflecting Francis’s Latin American context, expands the subject of solidarity in Catholic social teaching and thought. Yet, this ecological vision of family fails to attend to the problem of gender subordination latent in Catholic social teaching, including in its approaches to ecology. A vision of solidarity that eradicates gender and ecological subordination must elaborate a familial ecology characterized by both mercy and equality.

Domination is a structural complexity of chemical molecular graphs. A dominating set in a graphG=V,Eis a subsetS⊆Vsuch that each vertex inV\Sis adjacent to at least one vertex inS. The domination numberγGof a graphGis the minimum size of a dominating set inG. In this paper, computer-aided approaches for obtaining bounds for domination number on torus graphs are here considered, and many new exact values and bounds are obtained.

Mimarlık felsefesinde ―yer‖, ―mekan‖, ―uzam‖, ―boyut‖ gibi kavramlar sıklıklar tekrar tekrar ele alınıp tartışılır. Bu makalede en temelde aynı şeyin ―içerisi‖ ve ―dışarı‖ kavramları için yapılması denenmiştir. İç mekanlar genellikle binaların içi olarak düşünülür ve söz konusu bir dış mekan olduğunda, bu mekanın ―içerisi‖ olarak düşünülemeyeceği varsayılır. Dışarısı asla tam olarak bir iç mekan değildir. Bu makalede, bu görüş problematize edilmiş ve ―dışarının‖ da bir ―içerisi‖ olarak deneyimlenip deneyimlenemeyeceği araştırılmıştır. İlk olarak mekan sorununu ve bunun insan ile karşılıklı ilişkisini ele (...) alındı. Mekanı deneyimleme şekillerimiz ve bunların insan bedeni ve duyularıyla özsel ilişkisi içerinin ve dışarının anlamını tanımlamada bir zemin oluşturdu.

THE methodological principle known as Ockham’s Razor is usually formulated as “Entia non sunt multiplicanda praeter necessarium”. However, it is well known that neither this formulation of the principle nor the idea behind it come originally from William of Ockham. This particular formula is due to Leibniz, though Ockham’s works contain equivalent formulas: “Pluralitas non est ponenda sine necessitate”; “Si duae res sufficiunt ad eius veritatem, superfluum est ponere aliam rem”; “Frustra fit per plura, quod potest fieri per pauciora”. But (...) Duns Scotus had also used the same principle before Ockham and he refers it directly to Aristotle. If the Razor belongs to anyone then, it belongs to Aristotle, and the study of its exact meaning and value must begin with Aristotle’s views about it. It is interesting to note, in this respect, that the principle was recognized as Aristotle’s at least until the time of Galileo. Thus in his Dialogue concerning the Two chief World Systems Galileo supports his theory that “diurnal motion belongs to the earth alone rather than to the rest of the universe excepting the earth” by referring to “a very true maxim of Aristotle’s which teaches that ‘frustra fit per plura quod potest fieri per pauciora’.”.

There is a tension between Laudato si's consistent emphasis on relationships and interconnectedness and its acceptance of anthropocentrism. While Laudato si’ does reject certain problematic forms of anthropocentrism, the encyclical does not assert an alternative to this traditional framework. This article contends that “relatiocentrism” provides the best avenue for developing the convictions expressed within Laudato si’ while moving beyond the limitations of the encyclical itself. In so doing, this essay explores the use of narrative as a means of shaping identity (...) by mapping significant relationships and points of meaning. It examines the central anthropological claims of the encyclical and the tensions these create with anthropocentric narratives. And it examines relatiocentrism in light of the biblical creation accounts, the eschatological perspective of Laudato si’, and virtue ethics. The essay concludes by suggesting further theological and moral implications of this shift in perspective. (shrink)

The main point of our study is that the Kantian problem of a suitability between theory and practice, one of the key issues in Kant’s practical thinking in general, was erroneously perceived not only by those who defended it, and conceived of its possibility, but also by those who denied it and defended its impossibility. Our position, conversely, is that Kant, upon approaching a seemingly irresoluble problem, was forced to conceive of a via media, an “intermediate member of connection” between (...) theory and practice; an alternative which, in our view, does not arise out of mere necessity, rather is intimately interconnected from the mid-1770s onwards with the formation of Kant’s fundamental scheme of human knowledges, a scheme which, in its tridimensionality, establishes Pragmatic Anthropology as a third dimension of human knowledge and therefore as the only suitable soil for the dialogue between theory and practice, beyond the mere possibility or impossibility of the problem. This proposition, we hope, will enable us to ascertain what Kant envisages by the “talent of nature”, the special “act of the power of judgment” that is to serve as connecting member between theory and practice; to explain how Anthropology is to be seen as the natural abode for this mediating interplay; and, finally, to better position, as well as delimit, the scope of Kant’s anthropo-cosmological view of Man in the World, which is to be seen precisely between the merely rational of theory and the merely empirical of practice.

The central Fodorian objections to Inferential Role Semantics can be taken to include an ‘Analyticity Challenge’ and a ‘Circularity Challenge’, which are ultimately challenges to IRS explanations of concept possession. In this paper I present inferential role theories, critically examine those two challenges and point out two misunderstandings to which the challenges are exposed. I then state in detail a rationalist version of IRS and argue that this version meets the Fodorian challenges head on. If sound, this line of argument (...) shows that there is no problem of principle in the consideration of IRS as a good candidate for a theory of concepts.Las objeciones fodorianas en contra de una Semántica del Papel Inferencial pueden concebirse como incluyendo un ‘Reto de la Analiticidad’ y un ‘Reto de la Circularidad’, los cuales son principalmente retos a las explicaciones que SPI proporciona sobre la posesión de conceptos. En este artículo presento las teorías del papel inferencial, examino críticamente estos retos y señalo dos malentendidos a los cuales están expuestos. A continuación, presento con detalle una versión racionalista de SPI y defiendo que esta versión supera los retos fodorianos directamente. Si es correcta, esta línea argumentativa muestra que no hay un problema de principio en la consideración de SPI como una buena candidata para una teoría de los conceptos. (shrink)

Çin, son dönemlerde Körfez Bölgesine yönelik izlediği aktif politika, Çin Devlet Başkanı Xi Jipping’in (Şi Cinping), 7-9 Aralık 2022 tarihinde Körfez’e gerçekleştirdiği kapsamlı ziyaretle birlikte daha fazla dinamizm kazanmıştır. Bu ziyareti takiben yapılan analizler Çin’in, Körfez açılımını ABD’nin bölgesel hegemonyasını zayıflatmaya yönelik bir girişim olarak değerlendirmektedirler. Aynı ziyaret sırasında Pekin ve Riyad yönetimleri arasında imzalanan kapsamlı anlaşmalar ise ABD’nin Körfezdeki uzun erimli güvenlik partneri Suudi Arabistan’a ilişkin “eksen kayması” tartışmalarını başlattı. Bu çalışma güncelliğini koruyan iki tartışmanın kapsamlı bir muhakemesini yapmayı (...) hedeflemektedir. Bu amaçla uluslararası ilişkiler disiplinin son dönem fenomen teorisi olan hiyerarşinin ilgili argümanları kullanılmaktadır. Bu teorik çerçeveden hareketle, çalışmada ilk olarak Çin’in Körfez siyasetini şekillendiren stratejilerin fiyat arttırma (oubidding) ve negatif dengeleme (negative balancing) olduğu ve bu stratejilerin Körfez Bölgesi ülkeleri açısından yeni imkânlar yarattığı tespitinde bulunulmaktadır. Bunun yanı sıra Suudi Arabistan’ın, Çin ile gelişen ikili ilişkilerini hâlihazırda ABD ile sürdürmekte olduğu ilişkisine bir alternatif olarak görmediği, aksine Çin’in bahsi geçen stratejilerinden maksimum kazanım elde ederek otonomisini arttırmaya çalıştığı ayrıca belirtiliyor.

La filosofía nace y hunde sus raíces en ese tempestuoso navegar en el que se desenvuelve la vida de los hombres, tratando siempre de responder a necesidades históricas concretas y de buscar respuestas a los problemas de su propio tiempo. Esta solidaridad de la palabra filosófica con ese continuo variar que constituye la vida humana es lo que explica el hecho de que las concepciones filosóficas sean inevitablemente múltiples y diversas, y que los textos de los filósofos no puedan leerse, (...) si se quieren evitar deformaciones de todo tipo, aislándolos del contexto en el que surgieron. Los esfuerzos de aquellos que pretenden situar al discurso filosófico al margen y fuera de la historia real, presentando a la historia de la filosofía como una generación de conceptos nacidos de unos seres que parecen estar situados fuera del espacio y del tiempo, están condenados al fracaso, pues olvidan el hecho de la historicidad misma de la filosofía que va unida a una cultura y a una época determinadas. El presente volumen pretende mostrar el nexo constante que existe entre la historia de la filosofía y la vida de los hombres a través del análisis de cómo pensaron y qué significado y valor dieron a sus propios pensamientos algunos de los más ilustres filósofos que vivieron en tiempos históricos muy diversos. El estudio de los mismos, llevado a cabo por distintos especialistas, nos permitirá contemplar la pluralidad de distintos modos de filosofar y de las filosofías resultantes. (shrink)

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)
