Evolving definition of sociomuseology : proposal for reflection

Sociomuseology expresses a considerable amount of the effort made to suit museological facilities to the conditions of contemporary society. The process of opening up the museum, as well as its organic relation with the social context that infuses it with life, has resulted in the need to structure and clarify the relations, notions and concepts that may define this process. Sociomuseology is thus a scientific field of teaching, research and performance which emphasizes the articulation of museology, in particular, with the areas of knowledge covered by Human Sciences, Development Studies, Services Science, and Urban and Rural Planning. The multidisciplinary approach of Sociomuseology aims to strengthen the acknowledgement of museology as a resource for the sustainable development of Humanity, based on equal opportunities as well as social and economic inclusion. Sociomuseology bases its social intervention on mankind’s cultural and natural heritage, both tangible and intangible. What characterizes Sociomuseology is not so much the nature of its premises and its goals, as is the case with other areas of knowledge, but the interdisciplinary focus which makes it draw on perfectly consolidated areas of knowledge and relate them with Museology itself.

Estudios sonoros desde la Región Andina UIO-BOG = Sonic Studies from the Andean Region

El presente trabajo se basa en el análisis de las prácticas sonoras y, a partir de ahí, de una apuesta por un nuevo campo de estudios, el de los Estudios Sonoros; cuyo fin último es establecer una perspectiva epistemológica y política de las prácticas experimentales con sonido, en diálogo con proyectos provenientes de los Estudios Culturales, como son el proyecto modernidad/ colonialidad, las teorías poscoloniales y los estudios subalternos. Desde estas posiciones teóricas y políticas, estoy conciente de que el sonido, y sus posibilidades experimentales, articulan un régimen influyente en el mundo contemporáneo. Razón por la cual, sobre todo, esta es una reflexión desde las prácticas sonoras que surgen en dos ciudades andinas: Quito y Bogotá, como una expresión emergente para establecer encuentros Sur-Sur, que puedan generar diálogos epistemológicos sobre el sonido. En otras palabras, en este libro estoy proponiéndo a mis lectoras y lectores, una especie de “juego epistémico”: comprender el sonido como un lugar de conocimiento.Y el sonido es conocimiento precisamente porque el sonido nos permite vernos (y permite verme) como un sujeto históricamente ubicado. En el capítulo primero abordaré la pregunta de cómo se fue articulando el régimen discursivo del sonido como arte, dentro de diálogos y conflictos que se generaron en el contexto de la Guerra Fría que, para el caso de Latinoamérica, constituyó la transferencia de conocimientos articulados desde promesas como el desarrollismo y la modernización. También analizaré el cómo se configuraron, tanto en Quito como en Bogotá, las nuevas subjetividades “artísticas” frente al discurso de las vanguardias europeas del siglo XX y el experimentalismo estadounidense. Como verán mis lectoras y lectores, estos modelos, aparentemente originales e innovadores, fueron influidos por formas de saber y poder moduladas alrededor de la idea de la renovación de las artes a través del sonido, formulación que instaló el sonido como dispositivo/materia desde el cual, en detrimento de lo local, se articuló la fantasía de un universal deseado: las máquinas de sonido y de reproducibilidad técnica. En el segundo capítulo me centraré en algunas prácticas de experimentación sonora para indagar cuestiones como el estilo, procedimiento posmodernista ampliamente diseminado dentro de las instituciones artísticas y de éstas hacia la vida cotidiana. A partir de lo cual intentamos esclarecer el porqué de la confiscación y sometimiento de lo sonoro bajo el cuidadoso encierro del régimen discursivo del arte, que de manera eficiente lo absorbe como un “nuevo” medio para disciplinarlo y nombrarlo como proyecto sonoro, pieza sonora, instalación sonora, performance sonoro, acción sonora, objeto sonoro, paisaje sonoro, composición, loop. En otras palabras, cómo todo lo que genera el posmodernismo es apropiado por las universidades para crear la noción de “pastiche”, en donde todo cabe, bajo la indulgencia del “estilo”, procedimiento desde el cual se va instalando el régimen de verdad de un nuevo universal deseado: El Arte Sonoro. En este mismo capítulo, indagamos sobre las lógicas de producción de estas prácticas, para avanzar hacia las lógicas culturales donde lo sonoro se define y redefine por el posicionamiento y el lugar desde el que actúan los sujetos. Bajo estas consideraciones, queda planteada la propuesta, acuñada por esta investigación, la de un nuevo campo de estudio: Los Estudios Sonoros, propuesta que debe ser entendida como lo que algunos intelectuales latinoamericanos llaman epistemes emergentes11, precisamente porque esta investigación hace un esfuerzo por esclarecer las interdependencias existentes entre prácticas artísticas con sonido, el campo discursivo del arte y otras construcciones discursivas de la modernidad-colonialidad que establecen y regulan la formación del régimen sonoro. En el capítulo tercero analizaré cómo un “medio de creación” se vuelve hegemónico y cómo ciertos artistas que usan el sonido, bajo la pretensión de representar la marginalidad, marginalizan aún más a las personas que han sido históricamente subalternizadas. Seguido de este análisis, en el capítulo cuarto, indagamos sobre las tácticas que marcan nuevas formas de adhesión, de representación y de resistencia cultural, las mismas que son estrategias suplementarias frente, y en contra, de los discursos dominantes de las prácticas artísticas con sonido y las geopolíticas de conocimiento.

A similarity solution for a shock reflection problem in isentropic gas dynamics

A one-dimensional shock-reflection test problem in the case of slab, cylindrical, or spherical symmetry is discussed. The differential equations for a similarity solution are derived and solved numerically in conjunction with the Rankie-Hugoniot shock relations.

Synthesis of broadband anti-reflection coatings for spaceflight infrared optics

A synthesis method is outlined for the design of broadband anti-reflection coatings for use in spaceborne infrared optics. The Golden Section optimisation routine is used to make a search, using designated non-absorptive dielectric thin film combinations, for the coating design which fulfils the required spectral requirements using the least number of layers and different materials. Three examples are given of coatings designed by this method : (I) 1µm to 12µm anti-reflection coating on Zinc Sulphide using Zinc Sulphide and Yttrium Fluoride thin film materials. (ii) 2µm to 14µm anti-reflection coating on Germanium using Germanium and Ytterbium Fluoride thin film materials. (iii) 6µm to 17µm anti-reflection coating on Germanium using Lead Telluride, Zinc Selenide and Barium Fluoride. The measured spectral performance of the manufactured 6µm to 17µm coating on Germanium is given. This is the anti-reflection coating for the germanium optics in the NASA Cassini Orbiter CIRS instrument.

Precision of quasi-optical null-balanced bridge techniques for transmission and reflection coefficient measurements

The precision of quasioptical null-balanced bridge instruments for transmission and reflection coefficient measurements at millimeter and submillimeter wavelengths is analyzed. A Jones matrix analysis is used to describe the amount of power reaching the detector as a function of grid angle orientation, sample transmittance/reflectance and phase delay. An analysis is performed of the errors involved in determining the complex transmission and reflection coefficient after taking into account the quantization error in the grid angle and micrometer readings, the transmission or reflection coefficient of the sample, the noise equivalent power of the detector, the source power and the post-detection bandwidth. For a system fitted with a rotating grid with resolution of 0.017 rad and a micrometer quantization error of 1 μm, a 1 mW source, and a detector with a noise equivalent power 5×10−9 W Hz−1/2, the maximum errors at an amplitude transmission or reflection coefficient of 0.5 are below ±0.025.

Mountain waves in two-layer sheared flows: Critical-level effects, wave reflection, and drag enhancement

Internal gravity waves generated in two-layer stratified shear flows over mountains are investigated here using linear theory and numerical simulations. The impact on the gravity wave drag of wind profiles with constant unidirectional or directional shear up to a certain height and zero shear above, with and without critical levels, is evaluated. This kind of wind profile, which is more realistic than the constant shear extending indefinitely assumed in many analytical studies, leads to important modifications in the drag behavior due to wave reflection at the shear discontinuity and wave filtering by critical levels. In inviscid, nonrotating, and hydrostatic conditions, linear theory predicts that the drag behaves asymmetrically for backward and forward shear flows. These differences primarily depend on the fraction of wavenumbers that pass through their critical level before they are reflected by the shear discontinuity. If this fraction is large, the drag variation is not too different from that predicted for an unbounded shear layer, while if it is small the differences are marked, with the drag being enhanced by a considerable factor at low Richardson numbers (Ri). The drag may be further enhanced by nonlinear processes, but its qualitative variation for relatively low Ri is essentially unchanged. However, nonlinear processes seem to interact constructively with shear, so that the drag for a noninfinite but relatively high Ri is considerably larger than the drag without any shear at all.

Reflection iii: Transnationalisation, Television Formats and the Universal

This reflection argues that, despite various good reasons for approaching the notion of the ‘universal’ with caution, cultural theorists should give up their resistance to the universal. The prominence of formats in today’s television suggests that the time is ripe to do. Intentionally or not, accounts of difference implicitly also often reveal sameness; the more we probe heterogeneity, the more likely we are to encounter something that remains consistent and similar. Thus, it is time to collaborate with scholars from the numerous disciplines for which the universal has long had validity and pertinence.

MOOC experience: a participant's reflection

In this article the author reflects on the experiences of three Massive Open Online Courses (MOOCs): Edfuture (CHFE), Learning Design for 21st Century Curriculum (OLDS-MOOC), and Open Education (H817). Discussion draws on the perceived differences between OERs and MOOCs and questions the definitions of 'success', 'engagement', 'completion', and 'drop out' in a MOOC. Some lessons learnt as a participant are also discussed.

Projecting social and discursive identities through code-switching on facebook: the case of Greek Cypriots

Two varieties of Greek are spoken on the island of Cyprus: the local dialect, namely the Greek-Cypriot Dialect (GCD), and Standard Modern Greek (SMG). English is also influential, as Cyprus was an English colony until 1960. The dialect is rarely employed for everyday written purposes; however, it is now evident in computer-mediated communication (CMC). As a contribution to the field of code-switching in writing, this study examines how Greek-Cypriot internet users employ GCD, SMG, and English in their Facebook interactions. In particular, we investigate how identities (discursive and social) are performed and indexed through the linguistic choices of Greek-Cypriot internet users. The findings indicate that switches to GCD add a humorous tone and express solidarity and informality. SMG is mostly used for ‘official’ statements, and it is preferred by mature internet users, while English is used with expressions of affect and evaluative comments.

Unwriting food labels: discursive challenges in the regulation of package claims

This article examines the challenges resulting from the regulation of written discourse on food packages. It uses as a case study Hong Kong’s strict new food-labeling law that requires distributers and retailers to remove certain nutritional claims from packages of imported food before they sell them. This practice of redacting unlawful text on packages requires that distributers and retailers engage in complex processes of discursive reasoning, and it some- times results in packages that are difficult for customers to interpret. The case study highlights important issues in the regulation of commercial texts concerning collaboration, intertextuality, and the conflicts that can arise when the principals, authors, and animators of such texts have different agendas.
