Hector Postigo: The Digital Rights Movement [Audio interview]
No full textHector Postigo is the author of The Digital Rights Movement: The Role of Technology in Subverting Digital Copyright, in which he presents three case studies of a broad group of loosely knit organizations and individuals that address issues concerning fair use, free speech, privacy, and innovation in the digital environment. None of these concerns are new but the digital medium has changed the social, legal, and economic configuration in which the stakeholders operate. Users are no longer simply passive receivers of content but producers as well. Anyone with a computer can generate new and original online content, or can reuse and remix content in creative ways. This is a real watershed for creation and innovation and the digital rights movement is motivated by a vision of culture as shared and participatory. Expanded conceptions of fair use and free speech are essential to facilitate this vision. Individuals, organizations, and businesses that “own” content through government-granted copyrights have an interest in maintaining control in their works, for commercial and other reasons. The lines dividing users, creators, and content owners are very fluid, so much of this story is about the evolution of legal rules – government regulation – with regards to copyright and digital technology. By looking at three different cases in which the nascent digital rights movement struggled with the owners and producers of technology and commercial media over the meaning of fair use, free speech, and cultural production, Hector Postigo provides a unique perspective on the profound changes that digital technology has set in motion for cultures, economies, and polities.

No full textIn April 2018, 7 Husbands for Hurmuz (7 Kocalı Hürmüz), a popular musical comedy farce from Turkey, was staged by Arcola Alaturka, a Turkish-speaking theatre group based in East London. This production was performed by migrant actors and musicians with a predominantly migrant audience in mind. A production of 7 Kocalı Hürmüz was included in the Ankara State Theatre’s 2017–18 season, and another large scale production directed and produced by established comedian Müjdat Gezen has, at the time of writing, been selling out in Istanbul.
Set in a time when a man was permitted more than one wife, the plot of 7 Husbands for Hurmuz is a reversal of this situation: the central character is a woman (Hurmuz) who has married six husbands – none of whom knows about the others – as a way of solving her money problems. She sees each husband on a different day of the week, but mayhem ensues when Hurmuz falls in love with a seventh man, and then all seven turn up to see her on the same day. Farce, slapstick and absurdity combine in a satire, which is also an extension of folk theatre forms relating to specific Asian performance styles – drawing on both ortaoyunu and meddah traditions in Turkey. It can be argued that 7 Husbands for Hurmuz has caused controversy because although the play features an array of strong female characters, it has been perceived as both feminist and anti-feminist.
The following piece is a conversation between Naz Yeni, the director of the Arcola production, and Alejandro Postigo, author and performer of The Copla Musical, a tribute to the anti-Franco Spanish drag artist La Gitana. The Copla Musical explores an intercultural adaptation of the early twentieth-century Spanish folkloric song-form of copla, merged with elements found in Anglo-American musical theatre structures such as book musicals, revues and jukebox shows. Copla ceased to develop during Franco’s regime (1939–1975). Forty years later, The Copla Musical aims to rejuvenate copla interculturally. The show is supported by academic research that questions how to share the Spanish experience of copla with an international audience of diverse cultural backgrounds, and how to introduce copla’s background as a storytelling form, a folkloric genre and a subversive tool beyond the Spanish twentieth-century zeitgeist. The conversation explores the many challenges of translating songs and theatre works from one language to another for a multicultural and multilingual audience

The obscured hyper-energetic GRB 120624B hosted by a luminous compact galaxy at z=2.20
No full textContext. Gamma-ray bursts (GRBs) are the most luminous explosions that we can witness in the Universe. Studying the most extreme cases of these phenomena allows us to constrain the limits for the progenitor models.
Aims. In this Letter, we study the prompt emission, afterglow, and host galaxy of GRB 120624B, one of the brightest GRBs detected by Fermi, to derive the energetics of the event and characterise the host galaxy in which it was produced.
Methods. Following the high-energy detection we conducted a multi-wavelength follow-up campaign, including near-infrared imaging from HAWKI/VLT, optical from OSIRIS/GTC, X-ray observations from the Chandra X-ray Observatory and at submillimetre/millimetre wavelengths from SMA. Optical/NIR spectroscopy was performed with X-shooter/VLT.
Results. We detect the X-ray and NIR afterglow of the burst and determine a redshift of z = 2.1974 ± 0.0002 through identification of emission lines of [O ii], [O iii] and H-α from the host galaxy of the GRB. This implies an energy release of Eiso,γ = (3.0 ± 0.2) × 1054 erg, amongst the most luminous ever detected. The observations of the afterglow indicate high obscuration with AV > 1.5. The host galaxy is compact, with R1/2 < 1.6 kpc, but luminous, at L ~ 1.5 L∗ and has a star formation rate of 91 ± 6 M⊙/yr as derived from Hα.
Conclusions. As for other highly obscured GRBs, GRB 120624B is hosted by a luminous galaxy, which we also prove to be compact, with very intense star formation. It is one of the most luminous host galaxies associated with a GRB, showing that the host galaxies of long GRBs are not always blue dwarf galaxies, as previously thought

Highly efficient photodegradation of methylene blue by a composite photocatalyst of bismuth nanoparticles on silicon nanowires
No full textWhen synthetic dyes are used to embellish the world, the wastewater holding these hazardous materials is wantonly released into the biosphere. Appropriate treatment for such effluents is thereby indispensable. In this context, the present study was conducted to fabricate an eco-friendly, cost-effective and new bismuth modified silicon nanowires (Bi@SiNWs)-based photocatalysts toward superior photocatalytic degradation of methylene blue (MB) dye under both UV and solar irradiations. SiNWs were synthesized by silver-assisted chemical etching while Bi nanoparticles were anchored onto the NWs via thermal evaporation. By assessing the morphology, elemental composition, structure and crystallinity characteristics, these Bi@SiNWs nanocomposites are systematically identified. Extensive investigations of blank SiNWs and Bi@SiNWs optical properties — reflectance, transmittance, absorption coefficient, absorbance and optical band-gap — are presented. Near-perfect absorbance above 97%, over the visible wavelength region, has been achieved owing to the synergistic effect of Bi decoration on SiNWs. Accordingly, Bi@SiNWs showed remarkable photocatalytic ability for the degradation of MB up to 44% and 89% under UV and solar irradiation, respectively, only within 120 min. Repeated cycle runs revealed that the Bi@SiNWs composite photocatalyst exhibits strong reusability and photo-stability. Lastly, we will thoroughly provide the plausible mechanism for the photocatalytic degradation of MB over Bi@SiNWs. Our outcomes validate the potent role of Bi@SiNWs photocatalysts for effective environmental remediation.M. Naffeti and P.A.

Human nature from the perspective of science: a transhumanist response to Elena Postigo
No full textIn the article «Bioethics and transhumanism from the perspective of human nature», bioethicist Elena Postigo Solana presented an objection to the vision of human nature proposed by transhumanist philosophy. This objection was based on personalism, a philosophical framework according to which human nature is considered as dual, both physical and non-corporeal. This paper offers a response to Postigo\u27s objection from a scientific philosophical framework, that is, from a perspective in continuous communication with the available scientific evidence. It is concluded that the idea of human nature developed by Postigo lacks empirical support, making the concept of human nature an empty one and typical of pseudosecular argumentation. Therefore, it is recommended to avoid the use of the concept of human nature in the bioethical discussion.En el artículo «Bioética y transhumanismo desde la perspectiva de la naturaleza humana», la bioeticista Elena Postigo Solana presentó una objeción a la visión de naturaleza humana propuesta por la filosofía transhumanista. Dicha objeción partió del personalismo, un marco filosófico según el cual la naturaleza humana es considerada como dual, tanto física como no corpórea. En el presente documento se ofrece una respuesta a la objeción de Postigo desde un marco filosófico científico, es decir, a partir de una perspectiva en continua comunicación con la evidencia científica disponible. Se concluye que la idea de naturaleza humana desarrollada por Postigo carece de sustento empírico, por lo que el concepto de naturaleza humana se torna un concepto vacío y propio de la argumentación pseudosecular. Por lo anterior, se recomienda evitar el uso del concepto de naturaleza humana en la discusión bioética.
