Digital reading roomAngelė Pečeliūnaitė Summary The article actualizes electronic information services provided by a library. In order to better meet the in­creased needs of the readers, we propose to use the Cloud Computing technologies. These technological solutions facilitate the libraries’ “survival” issues and make it possible to offer the next-generation e-services – virtual digital reading rooms. The paper discusses changes of the readers’ in­formation needs, the identified problems and chal­lenges of libraries. The author models the flowchart of the modern library in the Community Cloud by applying the IaaS and SaaS Cloud Computing ser­vices. The proposed library structure provides a vir­tual space as desktop, which is identified as a virtual digital reading room whose features and options for users are discussed. Lent control of digital editions is offered by the 3M Cloud Library program which is tested in the world practice. According to the pro­posed scheme, the modeled virtual Cloud Library ef­fectively meets consumers’ needs and has become a library as a third place online.

Nowadays, ICTs is one of the major factors influencing urban development. Consequently, public spaces – an important urban subsystem – are shaped by interaction with the new technologies. This paper aims to present the ways, in which different ICT tools can increase the attractiveness and competitiveness of public spaces, in opposition to several approaches stating that technologies can only encourage segregation of individuals. The article is focused on possibilities to open the public realm for functions and activities that are usually regarded as private. The major roles that ICTs can play in the public space are: education, information, art and entertainment. Based on this classification various examples and proposals of ICTs interventions in public spaces are presented and analysed, including the Zaragoza’s Digital Mile, the Cloud at Athens and the concept of Flux Space. The specificity of this paper rests on a constant parallel drawn between the interventions around the globe and Romania, aiming to highlight the potential for competitiveness of Romanian public spaces, as a result of using various ICTs tools. Santrauka Pastaruoju metu IKT (informacijos ir komunikavimo technologijos) yra vienas pagrindinių miestų vystymui įtaką darančių veiksnių. Todėl viešosios erdvės – svarbus miestų posistemis – formuojamos veikiant naujosioms technologijoms. Šiame straipsnyje siekiama pristatyti būdus, kaip įvairiomis IKT priemonėmis pakelti viešųjų erdvių patrauklumą ir konkurencingumą, prieštaraujant požiūriams, teigiantiems, kad naujosios technologijos skatina žmonių atsiskyrimą. Pagrindinis dėmesys skiriamas galimybėms atverti į viešumą veiklas, įprastai laikomas privačiomis. Viešosiose erdvėse IKT priemonės daugiausia galėtų būti išnaudojamos lavinimui, informavimui, meninei veiklai ir pramogoms. Remiantis šiuo skirstymu analizuojami ir pristatomi įvairūs IKT naudojimo viešosiose erdvėse pavyzdžiai ir siūlymai: „Skaitmeninė mylia“ Saragosoje, „Debesys“ Atėnuose, „Flux erdvė“ ir kiti. Straipsnyje nuolat lyginamas patyrimas Rumunijoje ir patyrimas pasauliniu mastu, siekiant pabrėžti viešųjų erdvių Rumunijoje konkurencingumo potencialą, naudojant įvairias IKT priemones.

In the method that the oxygen-free copper strips are produced through undercurrent horizontal continuous casting-cold rolling process, there are some coarse grains, microscopic cracks, shrinkage, shrinkage and segregation defects in the oxygen-free copper strip billet, which debase the densities of the strip billet, and are the main reasons for rejected castings during machining operation. Through the orthogonal experiment of the technical factors in the casting process, the mapping model of artificial neural networks have been established using the data obtained in the experiments, which built the relationship among the densities of casting blank and technological factors. With the help of this model, the optimal casting conditions have been researched by using GA optimizations method and real experiments. The results show that micro-structure of castings was improved and the densities of the strip billets are enhanced.

Bipolar flaking as a means of reducing lithic raw material is known to have occurred since the time of the Lower Palaeolithic. As a strategy for working small bits of raw material, it is probable that it has a variety of important selective contexts. Assemblages from northeastern United States Paleo-Indian sites are used to test the hypothesis that bipolar artifacts in these systems represent a method of extending the utility of a transported, highly curated lithic toolkit through recycling. It is shown that what have been called pièces esquillées among these sites are in all probability cores for the derivation of small flakes. This is demonstrated by citing ethnoarcheological and technological data and by a spatial-statistical analysis of the distribution of “pièces esquillées” at the Debert site. The methodological problems related to the accurate functional identification of artifacts are explored and their impacts on archaeological arguments are also discussed. Also discussed are the difficulties in interpreting site activities on the basis of inter site differences in tool frequencies and proportions where assemblages have been affected by lithic recycling. Last, the theoretical significance of recycling through bipolar reduction is outlined as a strategy for solving the raw material and tool replacement problems as conditioned by Paleo-Indian settlement and technological systems.

Cualquiera que sea el enfoque adoptado para la enseñanza de la escritura, éste deberá lograr que todos los niños y jóvenes lleguen a dominar el sistema gráfico y ortográfico de su lengua, y para ello la didáctica prevista deberá otorgarle un espacio y un tiempo para su enseñanza, según el desarrollo de los proyectos y las secuencias didácticas planeadas. Comprender ese sistema gráfico y ortográfico es una condición necesaria, aunque no suficiente, para dominarlo, y dicha comprensión no debe confundirse con la memorización de las “reglas de ortografía” ni puede ser reemplazada por la tecnología de apoyo a la escritura, como los correctores ortográficos de los procesadores de texto, mediocres y poco sensibles al contexto sintáctico. Además, aunque se estén extendiendo usos relajados “del código” de escritura mediante ciertas tecnologías de la comunicación (en mensajes por celular, chats, blogs), los usuarios han de conocer todos los “registros” ortográficos y poder usarlos en los contextos apropiados. Finalmente, dicha comprensión es indispensable para entender y tomar una postura frente a las reformas ortográficas, más o menos frecuentes.Por lo anterior, compartimos con los maestros un conjunto de reflexiones y de tipos de actividades útiles para abordar la enseñanza de la ortografía del español en la escuela primaria, actividades cuya eficiencia se probó en la práctica con niños durante casi una década. Estos tipos de ejercicios son sólo una muestra, abierta para que el maestro pueda adaptarla, en contenido y forma, a la población de niños con la que trabaja. AbstractAny approach that could be adopted to teach writing must make that all children master the graphic and orthographic system of his language and, for that, the didactic design must include space and time enough for its teaching in accordance with the projects development and the planed didactic sequences. Understanding that graphic and orthographic system is a necessary but not sufficient condition to master it, and such comprehension must not be confused for the mechanic memorization of any set of "orthographic rules", either replaced by technological supports for writing such as word processors' spell checkers, particularly inefficient (in the case of Spanish writing) because of its lack of sensibility to syntactic context. Even if certain uses of "relaxed" orthographic codes are spread out by some communication platforms like cellular phones, chats and blogs, the users must handle all the orthographic registers and use them in appropriate contexts. Finally, such comprehension is indispensable for the treatment and adoption of a personal posture facing the more than less frequent orthographic reforms.So, we share with teachers a set of reflections and a set of types of activities useful for the teaching of the Spanish spelling at the primary school. The efficiency of those activities has been proved in practice with children during almost a decade. These kinds of exercises are only an open sample that the teacher could adapt, in form and content, to the population he is working with.Recibido: 05 de octubre de 2012Aceptado: 01 de abril de 2013

Este trabajo surge a partir de la investigación general de las técnicas hidropónicas teniendo en cuenta sus ventajas y desventajas para de esta forma poder encontrar aquel factor determinante a través de una comparación de técnicas hidropónicas que permitan clasificarlas y escoger la mejor opción que genere menos impacto ambiental negativo y demuestre ser más productivo en los entornos urbanos. Adicionalmente, un factor determinante en las ciudades es su espacio limitado por lo que la mejor opción también deberá incluir un óptimo manejo del espacio que permita a casi cualquier individuo poder aplicarlos desde su entorno sin recurrir a excesivas modificaciones. Como principal resultado se escogió a la Hidroponía recirculante como método predominante por los excelentes resultados que se obtienen con relación a los demás, adicionalmente, este puede ser fácilmente aplicado en los ambientes urbanos por su versatilidad y buen manejo de recursos.

ResumenLa mecánica de las estructuras de fábrica ha sido durante mucho tiempo de alguna manera abandonada en la enseñanza universitaria durante la licenciatura de arquitectura, en comparación con otros campos del conocimiento, como el hormigón armado, el acero y la madera. Una parte importante de nuestro patrimonio arquitectónico se erigió empleando estas técnicas ampliamente difundidas antaño, pero ahora olvidadas tanto en la práctica constructiva como en el marco teórico de la universidad, más centrado en tecnologías contemporáneas e innovadoras. Los avances del software computacional como son los modelos macro/micro de elementos finitos nos permiten realizar un análisis extremadamente complejo de estructuras de mampostería, pero paradójicamente, al mismo tiempo, se distancian de las limitaciones y la forma en que los antiguos concibieron y entendieron la arquitectura. Los maestros canteros fueron capaces de construir perfectamente sin la ayuda de tales pruebas precisas sobre los materiales. Por lo tanto, la mentalidad que hay que adoptar a la hora de abordar la enseñanza del comportamiento de las estructuras de mampostería es aquella en la que se estimule al alumnado a apropiarse del conocimiento no solo de la geometría, sino también y principalmente de las fases del proceso constructivo y de las técnicas acordes al período histórico. Solo una vez elaboradas ciertas hipótesis sobre ellas, se deberá comenzar con el cálculo gráfico-numérico. El objetivo del presente trabajo es exponer una metodología de enseñanza basada en programas de optimización y ejemplificada con el estudio de un caso concreto: el análisis de las arquerías de la Mezquita de Córdoba y de los posibles sistemas de contrarresto provisionales de empujes mediante tirantes y apeos, buscando la rentabilidad material de los mismos. Se plantea un recorrido progresivo, con un gradiente de conocimiento, a través de un estudio gráfico-numérico que engloba cuatro programas de diferente complejidad: Geogebra, Autocad + Excel, Maple y Sap2000, partiendo siempre de una hipótesis constructiva razonada. De esta manera, se resuelve el mismo problema de maneras diferentes para entender la estática gráfica desde varias perspectivas y ver cómo agilizar y “sistematizar” el cálculo de este tipo de estructuras mediante modelos elaborados con software de optimización matemática y programación simbólica, aprendiendo a la vez, cuáles son sus limitaciones y dificultades.Abstracthe mechanics of masonry structures have been for a long time pushed aside in university teaching during the bachelor degree of architecture in comparison with other fields of knowledge, such as reinforced concrete, steel and wood. An important part of our building heritage is raised using techniques once widely spread but now forgotten in the construction practice as well as in the theoretical university framework, more focused on contemporary and innovative technologies. Developments regarding computational software like FEM macro/micro modelling and discrete element methods allow us nowadays to carry out extremely complex analysis of accomplished masonry structures. Paradoxically, at the same time, this distances itself from the limitations and the way ancients conceived and understood architecture. Master bricklayers and stonemasons were able to build wonderfully without the help of such precise tests on the materials. Therefore, the mind-set when tackling the teaching of masonry structures should be that one where it is forced to the student body to take ownership of the knowledge of the geometry, constructive techniques and processes according to the precise historic period, keeping the tradition alive. The purpose of this work is to present a teaching methodology mainly based on optimization programs for masonry structures. It is illustrated with the analysis of the construction process of the colonnaded portico with double arches of the Great Mosque of Cordoba. The requirement of hypothetical auxiliary resources, such as wood props for the fixation of the capitals and tightening structures will also be considered. This methodology should be understood as a progressive path with a knowledge gradient through a graphical-numerical study that involves the use of four programs: Geogebra, Autocad + Excel, Maple and Sap2000. In this way, the same problem of the thrust line falling within the boundaries of the archery is solved in various ways to understand graphic statics from different perspectives. Moreover, creating a personal optimization model sheet will be taught as a way of accelerating and “systematizing” the calculation. The study will be followed by more complex analysis using symbolic calculation programs. As a result of the learning process described, the limitation and difficulties of each way of approaching the stability problem of the archery will be understood. Not only that, but also students will take advantage of the freedom offered when proceeding to the limit analysis suited to their own interests, always having graphical support.

A fines del año 2016 “CajaVecina”, filial del BancoEstado de Chile, único banco público, celebraba 10 años. La filial nacía como un modelo de negocio que buscaba democratizar los servicios financieros a todos los sectores del país, implementado en comercios del segmento microempresario por medio de un dispositivo electrónico “POS”. Más de 12 millones de clientes y no clientes de BancoEstado efectúan transacciones en línea. Con el paso del tiempo CajaVecina se convirtió en el servicio de corresponsalía bancaria más grande y exitoso del país, con una red de servicios financieros y no financieros distribuidos en todo el país a través del “Almacén de su barrio”, con más de 19 mil puntos de red. A pesar de lo anterior, BancoEstado y CajaVecina enfrentaba nuevos desafíos. La gran cantidad de clientes y de transacciones no eran fácil de sostener y hacían necesario implementar rápidamente una “estrategia de digitalización” planteada por el comité Ejecutivo para los años 2017-2020. La Gerente General de Caja Vecina, Marta Jancso, era consciente que a pesar de que contaba con la red de atención más extensa del país (equivalente a más de 8 veces la cantidad de sucursales bancarias existentes en Chile), era necesario un nuevo replanteamiento de la estrategia, ad portas de iniciar el nuevo ejercicio presupuestario. Ella miraba el mapa transaccional de los clientes de BancoEstado y la estrategia de digitalización del Banco para igual periodo y se pregunta si CajaVecina podrá continuar expandiendo su red de atención y sus servicios con el formato actual o debería efectuar ajustes a su estrategia, a la oferta de valor, a los servicios, a la tecnología o simplemente deberá resignarse a ver como las transacciones financieras en los celulares e internet terminan por derrumbar el presente exitoso de CajaVecina.

La presente investigación realizada en la Universidad Península de Santa Elena evalúa los sistemas de creencias que se vienen incrementando en las carreras sociales y tecnológicas en las que el sentido de valores es importante e indispensable, los postulantes de las ocho carreras ofertadas tales como Contadores Públicos, Enfermería, Turismo, Informática, Ingeniería civil, ingeniería en petróleos, Administración y Biología Marina mantienen sistemas de creencias puede incidir en el rendimiento escolar y en las expectativas con las que ingresan al sistema de educación superior. Se evalúan diez áreas de la prueba TCI Test de Ideas Irracionales Versión corregida y abreviada como son la Necesidad de aceptación, la presencia de auto expectativas, culpabilización, intolerancia a la frustración, niveles de preocupación y ansiedad, irresponsabilidad emocional, evitación de problemas, dependencia, indefensión y perfeccionismo. Este es un primer ensayo de sondeo sobre sistema de creencias basado en otros estudios de nivel superior y de poblaciones similares en que los resultados muestran índices parecidos de sistemas de creencias entre los estudiantes de las carreras en mención y luego se realiza un estudio comparativo con una población de la Carrera de Psicología que está por egresar. El análisis estadístico de los datos demostraría las áreas en las que desde el departamento de Bienestar Estudiantil convendría trabajar para cambiar ciertos esquemas de pensamiento que no permiten el normal desarrollo de actividades académicas. Se hace además un análisis por ítems de los porcentajes de irracionalidad en las áreas. Con la finalidad de conocer nuestra población estudiantil y poder preveer un mejor desempeño en su paso así como su permanencia por esta institución de educación superior. Se evaluó sin distinción a toda la población que ha sido convocada porque de esa manera se puede verificar con mayor exactitud los datos en mención. Se propone en base de esos datos iniciar un programa de intervención psicológica que permita afianzar de manera integral los cambios de sistemas de creencias y fomentar valores que vayan acordes con los cambios tecnológicos del área social así como rescatar principios y formas de pensamiento propios de la región y que vayan en función del buen vivir. La proyección que tengan sobre las escuelas y facultades deberá estar en relación con los perfiles profesionales de cada área de estudio.AbstractThis research conducted at the Santa Elena Peninsula University evaluates the belief systems that have been increasing in the social and technological careers in the sense of values is important and essential, applicants offered eight careers such as Accountants, nursing, Tourism, IT, civil engineering, petroleum engineering, Administration and Marine Biology held belief systems can affect school performance and expectations with entering the higher education system. Ten areas of the TCI Test Irrational ideas are revised and abbreviated version Need for acceptance test, the presence of self expectations, guilt, frustration intolerance, levels of worry and anxiety, emotional irresponsibility, problem avoidance, dependence are evaluated , helplessness and perfectionism. This is a first test survey on belief system based on other higher studies in similar populations and the results show similar levels of belief systems among students majoring in question and then a comparative study with a population of the School of Psychology that is graduating. Statistical analysis of the data would show the areas where from the Student Welfare Department should work to change certain ways of thinking that do not allow the normal development of academic activities. An analysis of the percentages for items of irrationality in the areas further ago. In order to meet our student population and to anticipate better performance in their step and their permanence in the institution of higher education. Were evaluated without regard to the whole population has been called because that way you can check more accurately the data in question. Is proposed on the basis of these data to initiate a program of psychological intervention to strengthen comprehensively changes belief systems and values that will promote technological change in line with the social area and rescue principles and ways of thinking from the region and to be based on good living. The projection having on schools and colleges should be related to the professional profiles of each study area.

What are the possibilities of a body? This is a question that is answered best by thinking prosthetically. After all, the possibilities of a body extend beyond flesh and bone. Asked another way, one might query: what are the affective capacities of bodies—animal or otherwise? Philosophers Gilles Deleuze and Félix Guattari focus on affectivity as capacity, on what the body does or can do; thinking through Baruch Spinoza’s writing on the body, they state, “we know nothing about a body until we know what it can do, in other words, what its affects are, how they can or cannot enter into composition with other affects” (257). If bodies are defined by their affective capacities, I wonder: how can prosthetics be used to alter dominant and dominating relationships between the human and the non-human animal, particularly as these relationships bear on questions of race? In this essay, I forward a contemporary media installation, “The Slug Princess”, as a productive site for thinking through the prosthetic possibilities around issues of race, animality, and aesthetics. I contend that the Degenerate Art Ensemble’s installation works through uncommon prosthetics to activate what Deleuze and Guattari describe as becoming-animal. While animality has historically been mobilized to perpetuate Orientalist logics, I argue that DAE’s becoming-slug rethinks the capacities of the body prosthetically, and in so doing dismantles the hierarchy of the body normativity.The Degenerate Art Ensemble (DAE) is a collective of artists with international showings co-directed by Haruko Crow Nishimura, originally from Japan, and Joshua Kohl, from the United States. The ensemble is based in Seattle, Washington, USA. The group’s name is a reference to the 1937 Degenerate Art Exhibition in Munich, Germany, organized by Adolf Ziegler and the Nazi Party. The exhibition staged 650 works from what Nazi officials referred to as “art stutterers”, the pieces were confiscated from German museums and defined as works that “insult German feeling, or destroy or confuse natural form or simply reveal an absence of adequate manual and artistic skill” (Spotts 163). DAE “selected this politically charged moniker partly in response to the murder in Olympia [Washington] of an Asian American youth by neo-Nazi skinheads” (Frye). DAE’s namesake is thus an embrace of bodies and abilities deemed unworthy by systems of corrupt power. With this in mind, I argue that DAE’s work provides an opportunity to think through intersections of prostheticity, animality, and race.“The Slug Princess” is part of a larger exhibition of their work shown from 19 March to 19 June 2011 at the Frye Art Museum in Seattle. The installation is comprised of two major elements: a crocheted work and a video projection. For me, both are prosthetics.A Crocheted Prosthetic and Orientalist AnimalityThe crocheted garment is not immediately recognizable as a prosthetic. It is displayed on a mannequin that stands mostly erect. The piece, described as a headdress, is however by no means a traditional garment. Yellow spirals and topographies flow and diverge in tangled networks of yarn that sometimes converge into recognizable form. The knit headdress travels in countless directions, somehow assembling as a wearable fibrous entity that covers the mannequin from head to ground, spreading out, away, and behind the figuration of the human. In slumped orbs, green knit “cabbages’ surround the slug princess headdress, exceeding the objects they intend to represent in mass, shape, and affect. In this bustling excess of movement, the headdress hints at how it is more than a costume, but is instead a prosthetic.The video projection makes the prosthetic nature of the crocheted headdress evident. It is a looped performance of Nishimura that runs from ceiling to floor and spans the semi-enclosed space in which it is displayed. In the video, Nishimura walks, then crawls – slowly, awkwardly – through a forest. She also eats whole cabbages, supporting procedure with mouth, foot, and appendage, throwing the function of her body parts into question. The crocheted element is vital to her movement and the perception of her body’s capacities.As Nishimura becomes slug princess, the DAE begins to intervene in complex regimes of racial identification. It is imperative to note that Nishimura’s boy gets caught up in interpretive schemas of Western constructions of Asians as animals. For example, in the early diaspora in the United States, Chinese men were often identified with the figure of the rat in 19th-century political cartoons. Mel Y. Chen points to the ways in which these racialized animalities have long reinforcing the idea of the yellow peril through metaphor (Chen 110-111). These images were instrumental in conjuring fear around the powerfully dehumanizing idea that hordes of rats were infesting national purity. Such fears were significant in leading to the Chinese exclusion acts of the United States and Canada. Western tropes of Asians find traction in animal symbolism. From dragon ladies to butterflies, Asian femininity in both women and men has been captured by simultaneous notions of treachery and passivity. As Nishimura’s body is enabled by prosthetic, it is also caught in a regime of problematic signs. Animal symbolism persists throughout Asian diasporic gender construction and Western fantasies of the East. Rachel C. Lee refers to the “process whereby the human is reduced to the insect, rodent, bird, or microbe” as zoe-ification, which she illustrates as a resolute means of excluding Asian Americans from species-being (Lee Exquisite 48). DAE’s Slug Princess, I argue, joins Lee’s energies herein by providing and performing alternative modes of understanding animality.The stakes of prosthetics in becoming-animal lie in the problem of domination through definition. Orientalist animality functions to devalue Asians as animals, ultimately justifying forms of subordination and exclusion. I want to suggest that becoming-slug, as I will elaborate below, provides a mode of resisting this narrow function of defining bodies by enacting prosthetic process. In doing so, it aligns with the ways in which prosthetics redefine the points of delineation against normativity. As Margarit Shildrick illuminates, “once it is acknowledged that a human body is not a discrete entity ending at the skin, and that material technologies constantly disorder our boundaries, either through prosthetic extensions or through the internalization of mechanical parts, it is difficult to maintain that those whose bodies fail to conform to normative standards are less whole or complete than others” (24). DAE’s Slug Princess transmutates how animality functions to Orientalize Asians as the degenerate other, heightening the ways in which prosthetics can resist the racialized ideologies of normative wholeness.Why Prosthetics? Or, a Comparative Case in Aesthetic AnimalityDAE is of course not alone in their animalistic interventions. In order to isolate what I find uniquely productive about DAE’s prosthetic performance, I turn to another artistic alternative to traditional modes of Orientalist animality. Xu Bing’s performance installation “Cultural Animal” (1994) at the Han Mo Art Center in in Beijing, China can serve as a useful foil. “Cultural Animal” featured a live pig and mannequin in positions that evoked queer bestial sexuality. The pig was covered in inked nonsensical Roman letters; the full body of the mannequin was similarly tattooed in jumbled Chinese characters. The piece was a part of a larger project entitled “A Case Study of Transference”. According to Xu’s website, “the intention was both to observe the reaction of the pig toward the mannequin and produce an absurd random drama—an intention that was realized when the pig reacted to the mannequin in an aggressively sexual manner” (Xu). The photographs, which were a component of the piece, indeed evoke the difficulty of the concept of transference, imbricating species, languages, and taboos. The piece more generally enacts the unexpected excesses of performance with non-scripted bodies. The pig at times caresses the cheek of the mannequin. The sensuous experience is inked by the cultural confusion that images the seeming sensibility of each language. Amidst the movement of the pig and the rubbings of the ink, the mannequin is motionless, bearing a look of resigned openness. His eyes are closed, with a slight furrowing of the brow and calm downturned lips. The performance piece enacts crossings that reorient the historical symbolic force of racialization and animality. These forms of species and cultural miscegenation evoke for Mel Y. Chen a form of queer relationality that exemplifies “animalities that live together with race and with queerness, the animalities that we might say have crawled into the woodwork and await recognition, and, concurrently, the racialized animalities already here” (104). As such, Chen does the work of pointing out how Xu destabilizes notions of proper boundaries between human and animal, positing a different form of human-animal relationality. In short, Xu’s Cultural Animal chooses relationality. This relationality does not extend the body’s capacities. I argue that by focusing in on the pivotal nature of prosthesis, DAE’s slug activates a becoming-animal that goes beyond relationship, instead rethinking what a body can do.Becoming-Slug: Prosthetics as InterventionBy way of differentiation, how might “The Slug Princess” function beyond symbolic universalism and in excess of human-animal relations? In an effort to understand this distinction, I forward DAE’s installation as a practice of becoming-animal. Becoming-animal is a theoretical intervention in hierarchy, highlighting a minoritarian tactic to resist domination, akin to Shildrick’s description of prosthetics.DAE’s installation enacts becoming-slug, as illustrated in an elaboration of Deleuze and Guattari’s concept they argue: “Becoming-animal always involves a pack” “a multiplicity” (Deleuze and Guatttari 239). The banner of becoming-animal is “I am legion”. DAE is and are a propagation of artists working together. They enact legion. Led by a pack of collaborators, DAE engage a range of artists in continual, ongoing, and fluctuating process. Their current collaborators include (and surpass): architect/designer Alan Maskin, costume designer ALenka Loesch, dancer/singer Dohee Lee, performance artist/expressionist/songwriter/shape-shifter Okanomodé, and sound/installation artist Robb Kunz. For the broader exhibition at the Frye, they listed the biographies of fifteen artists and the names of around 200 artists. Yet, it is not the mere number of collaborators that render DAE a multiplicity – it is the collaborative excess of their process that generates potential at the intersection of performance and prosthetic. Notably, it is important that the wearable prosthetic headpiece used in “Slug Princess” was created in collaboration. “The contagion of the pack, such is the path becoming-animal takes” (Deleuze and Guattari, 243). Created by Many Greer but worn by Nishimura, it weighs on Nishimura’s body in ways that steer her performance. She is unable to stand erect as the mannequin in the exhibition. The prosthetic changes her capacities in unpredictable ways. The unexpected headdress causes her to hunch over and crawl, pushing her body into slow contact with the earth. As the flowing garment slows her forward progress, it activates new modes of movement. Snagging, and undulating, Nishimura moves slowly over the uncertain terrain of a forest. As Greer’s creation collides with Nishimura’s body and the practice of the dance, they enact becoming-slug. This is to suggest, then, following Deleuze and Guattari’s affective understanding of becoming-animal, that prosthetics have a productive role to play in disrupting normative modes of embodiment.Further, as Deleuze and Guattari indicate, becoming-animal is non-affiliative (Deleuze and Guattari 238). Becoming-animal is that which is “not content to proceed by resemblance and for which resemblance, on the contrary, would represent an obstacle or stoppage” (Deleuze and Guattari 233). Likewise, Nishimura’s becoming-slug is neither imitative (305) nor mimetic because it functions in the way of displaced doing through prosthetic process. Deleuze and Guattari describe in the example of Little Hans and his horse, becoming-animal occurs in putting one’s shoes on one’s hands to move, as a dog: “I must succeed in endowing the parts of my body with relations of speed and slowness that will make it become dog, in an original assemblage proceeding neither by resemblance nor by analogy” (258). The headdress engages an active bodily process of moving as a slug, rather than looking like a slug. Nishimura’s body begin as her body human begins, upright, but it is pulled down and made slow by the collaborative force of the wearable piece. As such, DAE enacts “affects that circulate and are transformed within the assemblage: what a horse [slug] ‘can do’” (257). This assemblage of affects pushes beyond the limited capacities of the screen, offering new productive entanglements.The Stuplime Loop as ProstheticTo the extent that conceiving of a headdress as a collaborative bodily prosthetic flows from common understandings of prosthetic, the medial interface perhaps stirs up a more foreign example of prosthesis and becoming-animal. The medial performance of DAE’s “The Slug Princess” operates through the video loop, transecting the human, animal, and technological in a way that displaces being in favor of becoming. The looping video creates a spatio-temporal contraction and elongation of the experience of time in relation to viewing. It functions as an experiential prosthetic, reworking the ability to think in a codified manner—altering the capacities of the body. Time play breaks the chronological experience of straight time and time as mastery by turning to the temporal experience as questioning normativity. Specifically, “The Slug Princess” creates productive indeterminacy through what Siane Ngai designates as “stuplimity”. Ngai’s punning contraction of stupidity and sublimity works in relation to Deleuze’s thinking on repetition and difference. Ngai poses the idea of stuplimity as beginning with “the dysphoria of shock and boredom” and culminating “in something like the ‘open feeling’ of ‘resisting being’—an indeterminate affective state that lacks the punctuating ‘point’ of individuated emotion” (284). Ngai characterizes this affecting openness and stupefying: it stops the viewer in their/her/his tracks. This importation of the affective state cannot be overcome through the exercise of reason (270). Departing from Kant’s description of the sublime, Ngai turns to the uglier, less awe-inspiring, and perhaps more debase form of aesthetic encounter. This is the collaboration of the stupid with the sublime. Stuplimity operates outside reason and sublimity but in alliance with their processes. Viewers seem to get “stuck” at “The Slug Princess”, lost in the stuplimity of the loop. Some affect of the looping videos generates not thoughtfulness or reflection, but perhaps cultural stupidity – the relative and temporary cessation or abatement of cultural logics and aesthetic valuations. The video loop comes together with the medial enactment of becoming-slug in such a manner that performs into stuplimity. Stuplimity, in this case, creates an opening of an affectively stupid or illegible (per Xu) space/time alternative being/becoming. The loop is, of course, not unique to the installation and is a common feature of museum pieces. Yet, the performance, the becoming-slug itself, creates sluggishness. Ngai posits that sluggishness works out the boredom of repetition, which I argue is created through the loop of becoming-slug. The slug princess’ slowness, played in the loop creates a “stuplimity [that] reveals the limits of our ability to comprehend a vastly extended form as totality” (271). That is, the loop, by virtue of its sluggishness, opens up becoming-animal not as a finite thing, but as an ongoing, cycling, and thoughtlessly tedious process. DAE’s installation thus demonstrates an attempt to adopt prosthetics to rethink the logics of control and power. In his writing on contemporary shifts in prosthetic function, Paul Preciado argues that digitalization is a core component of the transition from prosthetics to what emerge as “microprosthetic”, in which “power acts through molecules that incorporate themselves into our [bodies]” (78-79). I would like to consider the stuplime loops of becoming-slug to counter what Preciado describes as an “ensemble of new microprosthetic mechanisms of control of subjectivity by means of biomolecular and multimedia technical protocols” (33). Emerging in the same fashion as microproesthetics, which function as modes of control, the stuplime loops instead suspend the logics of control and power enabled by dominant modes of microprosthetic technologies. Rather than infesting one’s body with modes of control, the stuplime loops hijack the digital message and present the possibility of thinking otherwise. In her writing on queer cyborgs, Mimi Nguyen argues that “as technologies of the self, prostheses are both literal and discursive in the digital imaginary. They are a means of habitation and transformation, a humanmachine mixture engaged as a site of contest over meanings – of the self and the nonself” (373). Binaries perhaps structure a thinking between human and animal, but prosthetics as process goes beyond the idea of the cyborg as a mixture and maps a new terrain altogether.ReferencesChen, Mel Y.
