Yaxchilán: Chiapas
No full textLa información de esta miniguía se basa en los trabajos de Roberto García Moll y Daniel Juárez Cossío.Yaxchilán es uno de los sitios más notables del periodo Clásico de la región maya (250-900 d.C.). De pequeña aldea de agricultores y cazadores se convirtió en un lugar destacado en el ámbito de su región. Se piensa que fue importante desde el gobierno de Cráneo-Mahk'¡na l, señor de Yaxchilán, alrededor del año 410 d.C. Para ese momento Tikal dominaba aún la región y Yaxchilán era un puerto fluvial. Es probable que con el ascenso de Cráneo-Mahk'ina ll al trono de Yaxchilán (en 526 d.C.) la ciudad se convirtiera en capital regional, como lo denota la presencia de su glifo emblema en otras localidades.</p
Complex scale-free networks with tunable power-law exponent and clustering
No full textThis article is made available through the Brunel Open Access Publishing Fund. It is distributed under a Creative Commons License (http://creativecommons.org/licenses/by/3.0/). Copyright @ 2013 Elsevier B.V.We introduce a network evolution process motivated by the network of citations in the scientific literature. In each iteration of the process a node is born and directed links are created from the new node to a set of target nodes already in the network. This set includes mm “ambassador” nodes and ll of each ambassador’s descendants where mm and ll are random variables selected from any choice of distributions plpl and qmqm. The process mimics the tendency of authors to cite varying numbers of papers included in the bibliographies of the other papers they cite. We show that the degree distributions of the networks generated after a large number of iterations are scale-free and derive an expression for the power-law exponent. In a particular case of the model where the number of ambassadors is always the constant mm and the number of selected descendants from each ambassador is the constant ll, the power-law exponent is (2l+1)/l(2l+1)/l. For this example we derive expressions for the degree distribution and clustering coefficient in terms of ll and mm. We conclude that the proposed model can be tuned to have the same power law exponent and clustering coefficient of a broad range of the scale-free distributions that have been studied empirically.EPSR
Moral Reforma: Tabasco
No full textA través de las inscripciones mayas se sabe que muchos sitios, relativamente importantes dentro de su esfera geopolítica, poseían lo que entre los epigrafistas se denomina "glifo emblema", cuya representación se ha interpretado como una toponimia con la cual se identifican algunas "ciudades" del periodo Clásico. En el caso de Moral-Reforma se conoce el glifo emblema; sin embargo, éste aún no se ha descifrado con certeza. El sitio, según las referencias más tempranas que se conservan, y que datan de principios del siglo xx, recibió diversos nombres: La Reforma ll, Morales, Balancán o bien la combinación de éstos. Ello generó cierta confusión en cuanto a su identificación' Actualmente se ha respetado el nombre de Moral-Reforma.</p
Labirynt tożsamości. Czeczeńska lezginka w perspektywie antropologii tańca
No full textCelem pracy jest antropologiczna analiza wybranej formy tradycyjnego tańca czeczeńskiego, lezginki. Autor stawia tezę o istotnej roli tego fenomenu kultury w międzypokoleniowym przekazie kulturowym w społeczności Czeczenów (inaczej Wajnachów) oraz obecnych w tańcu, dających się obserwować uniwersaliach charakterystycznych dla ich zbiorowej tożsamości. W toku wywodu powołuje się na prace antropologów amerykańskich i polskich, wykorzystując do opisu pojęcia takie jak wiedza ucieleśniona, kontekst oraz uniwersalia kulturowe. Podejmuje analizę poszczególnych elementów tańca, w tym spiralę jako formę organizującą ruch tancerzy, a także relacje tancerz-tancerka oraz tancerz-widownia. Każdy z elementów opatruje komentarzem kulturowym. Ważnym punktem odniesienia jest kategoria labiryntu. Autor przywołuje badania potwierdzające związek lezginki ze starogreckim mitem o Tezeuszu i labiryntem jako bogatym semantycznie tropem interpretacji czeczeńskiego chełchar (tańca). W końcowej części pracy zawarty jest wniosek o ograniczeniach, jakim podlega antropologiczna analiza form tanecznych.The paper constitutes an anthropological analysis of a selected form of traditional Chechen dance – the Lezginka. The author formulates a hypothesis on the essential role of this cultural phenomenon in the intergenerational transmission of culture in the Chechen (sometimes referred to as Nakh/Vainakh) community, and on the observable universal traits present in the dance, characteristic for the Chechen collective identity. The author refers to works of American and Polish anthropologists, employing such notions as „embodied knowledge”, „context” and „cultural universals”. The author analyses various elements of the dance, including the spiral as a form organizing the dancers’ movement, as well as the relationship between the male and female dancers, and also between the dancer and the audience, providing a cultural commentary for each element. The category of the labyrinth is mentioned as well as an important point of reference; the author cites research validating the connection between the Lezginka and the ancient Greek myth of Theseus as well as with the motif of labyrinth as a semantically rich interpretative perspective on Chechen chelchar dance. The final part of the paper presents conclusions on the limitations to which an anthropological analysis of dance forms is subjected
John Gay's the beggar's opera: early eighteenth-century responses in the arts to cultural, sociological and political issues in London life
No full textDiffering responses in art media to these contemporary issues of London life are explored, taking John Gay's the Beggar's Opera as the focal point for discussion. Initially, a general survey is made of Gay's role as cultural, social and moral critic. Comparison with George Frederick Handel's Floridante allows Gay's work to be placed in the context of operatic responses to contemporary society, highlighting usage both of overt portrayal and indirect satire. Gay's approach to political issues is examined alongside that of Dean Swift's Gulliver's Travels enabling an estimation to be made of the effectiveness of these art media as tools of political propaganda. Similarly, responses in the field of painting are discussed in the light of representative works of James Thornhill and William Hogarth's A Harlot's Progress and A Rake's Progress. In considering all these responses it is noted that art can be interpreted at differing levels, from the sophisticated to the naive. All these art media are then placed in the context of artistic philosophy of the period, thus facilitating an objective assessment of the parallels and differences of art's responses to contemporary issues. Taking into account inherent limitations in the media, to conclude our study, Hogarth's The Beggar's Opera Scenes are compared and contrasted with Gay's prototype. The thesis highlights the trend towards realism in the arts during this period. Nevertheless, we are left with the conundrum that art, 'per se', can only 'mirror' life. It does not necessarily solve its problems. Thesis submitted in fulfilment of the requirements for the degree of Master of Arts in Music. University of Durham Department of Music 198

This volume presents eleven influential essays from throughout his career, as well as two new and previously unpublished essays, &apos;The Problem of Fr** W*ll&apos; and &apos;Ability&apos;. The essays include discussions of determinism, moral responsibility, &apos;Frankfurt counterexamples&apos;, the meaning of &apos;the ability to do otherwise&apos;, and the very definition of free will, as well as critiques of writings on the topic by Daniel Dennett and David Lewis. An introduction by the author discusses the history of his thinking about free will. The volume will be a valuable resource for those looking to engage with van Inwagen&apos;s significant contributions to this perennially important topic.</jats:p
Museo Baluarte de Santiago: Veracruz
No full textEsta miniguía se basa en los trabajos de la Mtra. Hist. Gema Aurora Lozano y Nathal, M. Arq. Rest. Juan José Ramírez Jara y Anaya, Antrop. Soc. Daniel Nahmad Molinari y Arqlgo. y M. C. A. Humberto Besso-Oberto González.En 1615, por acuerdo de Felipe ll, la Villa Rica de la Vera-Cruz fue elevad a la categoría de ciudad y en 1621, el ingeniero y cosmógrafo militar Adrián Boot fue nombrado por el virrey marqués de Gálvez, director y técnico de las obras para la defensa de la ciudad. Se construyen entonces dos baluartes frente al mar, el del norte y el del sur, que junto con San Juan de Ulúa formaron un triángulo estratégico para la protección de la ciudad y de las islas. La construcción del baluarte sur, diseñado por Boot, se concluyó en el año 1635.</p
The Soul of the Golem
No full textThere are many ways of interpreting the so-called ‘new technologies’. One of the most interesting is that which stems from defining them as a social imaginary, and therefore, as collective beliefs, fears and hopes. It is common to attribute to technologies all manner of threats that, founded or not, are real in the measure that the society makes decisions and acts in a way consistent with this conviction. The fears and anxieties of society lead to a consideration of the limits of the human that technologies transgress. Among the figures with which one speaks about these limits there is Frankenstein, the modern Prometheus, which threatens modern fantasies with its deformity. There is, however, another man-made creature that can serve to orient our reflection, the Golem.
In 1609, 400 years ago, Rabbi Loew died. He is credited with the creation of a homunculus by combining of secret codes. The problem of the Golem was its imperfect soul made manifest in its lack of speech. Its silent presence was a source of great fear in the community that finally asked to get rid of the creature. These figures of monstrosity, Frankenstein and above all Golem, will help us to make technologies understand from the fear that society projects onto them, and this will lead us to the question concerning the imaginary fears of the technological system
Exploration of the antimicrobial and magnetic properties of ƞ⁶-arene-ƞ⁵-cyclopentadienyliron(ll)-derived dendrimers
No full textThis thesis reports a new family of cationic organometallic dendrimers as an antimicrobial
platform and a magnetoceramic precursor. The synthesis of these dendrimers involved well-established
chemistries, especially the facile nucleophilic aromatic substitution (SNAr) reaction of
ƞ⁶-arene-ƞ⁵-cyclopentadienyliron(ll) ([ƞ⁶-chloroarene-ƞ⁵-CpFe]+) complex with a phenolic
nucleophile. The use of [ƞ⁶-chloroarene-ƞ⁵-CpFe]+ resulted in iron-containing dendrimers that
undergo SNAr reaction with nucleophilic functional molecules to give bifunctional dendrimers,
and also have implications for antimicrobial activity and ferromagnetism. Indeed, the dendrimers
yielded bifunctional, photoactive and redox-active, as well as dual-emissive dendrimers.
Importantly, the dendrimers were active against drug-resistant bacteria, including methicillinresistant
Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecium. The
activity depends on the nature of the counteranion because changing from BF4
- to PF6
-
counteranion enhanced activity. Also, the dendrimers induced oxidative stress on MRSA and
disrupted the microbial cell membrane. Functionalization of the dendrimers with known
antimicrobial agents, quaternary ammonium groups or 2-mercaptobenzothiazole, yielded hybrid
antimicrobial dendrimers with enhanced activity, especially at higher generation. On pyrolysis at
900 °C in an inert atmosphere, these dendrimers yielded ceramics with room temperature, soft
ferromagnetism. The magnetism was tuned via dendritic effects or functionalization with cobalt.
Indeed, saturation magnetization (Ms) and coercivity (Hc) decreased with increase in dendrimer
generation. Incorporating Co increased Ms and Hc at the second-generation but decreased these
properties at the zeroth- and first-generations. Overall, [ƞ⁶-chloroarene-ƞ⁵-CpFe]+ -derived
dendrimers are a versatile platform for accessing functional, in particular antimicrobial and
magnetic, materials
