Investigation of ZnS Nanotubes Films: Morphological, Structural and Optical Properties
Authors: Abdallah Bassam , Kakhia M. , Alkafri N.
Published: November 2019

Pb doped ZnS nanotubes films have been deposited on glass and Si (100) substrates by a thermal evaporation technique. Energy dispersive spectroscopy (EDX) analysis has been used to identify the element’s compositions. Pb concentration in the prepared films was increased from 0 to about ~6 wt. %. The X- Ray Diffraction (XRD) pattern exhibited the wurtzite structure of ZnS with (002) preferred orientation. It shows that the calculated grain size increased with increase in Pb concentration. XRD analysis was also used to determine the strain in the films. Morphology and thickness of the films were obtained from surface and cross section of the films, using scanning electron microscopy (SEM) images. SEM images have confirmed the ZnS nanotubes and modifications of the morphology when adding Pb. Atomic force microscope (AFM) and SEM characterization have been shown dense structure and demonstrated the growth of spherical forms with nanostructure (nanotubes not created) for a film deposited without doping (0 wt. %). The transparency of the films has been deduced from UV-Vis spectra, where the band gap increased with increase in Pb concentration
Study on the Preparation and Properties of Micro-Nano Structure on the Surface of 304 Stainless Steel by One-Step Anodizing

Published: November 2019

The micro-nanostructures were prepared on the surface of 304 stainless steel by one-step anodizing with perchloric acid-ethylene glycol electrolyte. The morphologys, phase behaviour and microstructures of the prepared micro-nanostructures were characterized by SEM, XRD and metallographic examinations. The corrosion resistance and hydrophobic properties of 304 stainless steel after anodizing at different times were studied by Tafel test and contact angle test. The results show that when the anodization voltage is 30V, the electrolyte is 5vol% perchloric acid-ethylene glycol, the reaction temperature is 0 ± 5 ° C，and the anodization time is 15min, a honeycomb micro-nanostructure having an average pore diameter of 143 nm, an average pore spacing of 124 nm and a uniform distribution can be prepared on the surface of 304 stainless steel. The prepared nanostructure has a contact angle with water of 128° and a hydrophobicity of 86.3%, which corrosion resistance is 21 times higher than that of ordinary 304 stainless steel in 3.5 wt% NaCl solution. Metallographic microscopic observation and XRD indicate that the anodic oxidation begins along the grain boundary of the austenite, and then the micro-nano holes grow on the austenite and fill the entire austenite phase. Finally, Fe2O3 structure with uniformly distributed micro-nano pores is formed on the surface of the stainless steel.
Environmental indoor thermal control of extra virgin olive oil storage room with phase change materials
Authors: Barreca Francesco , Praticò Pasquale
Published: November 2019

The quality of extra virgin olive oil (EVOO) is strongly correlated to storage temperature, in fact the storage conditions (packaging material, oxygen, temperature, and light) alters not only the fatty acid alkyl esters (FAEE) of the olive oil but also other quality parameters such as peroxide, making the oil incompatible to the high quality EVOO. During storage of EVOO the polyphenols tend to decrease and compromise the dietetic and nutritional qualities and taste and produce harmful substances. The storage temperature, more than 24°C, influences quite a lot FAEE especially for long-term conservation. High storage temperature leads to degradation of oil quality in the long term while low temperature develops rancidity quickly, reducing the consumer’s demand. Low storage temperature also affects the EVOO quality but in a lesser way than high storage temperature. The present study proposes the use of a control temperature system based on the application of phase change materials (PCM) on the buildings envelope. A specific case study was considered to evaluate the effect on use of PCM. The building analysed was an olive mill building situated in Scido a small town in the province of Reggio Calabria located in southern Italy. The intervention on the EVOO storage room to improve the energy savings for temperature control was based on the insulation of the partitions and the installation of a false ceiling to limit the air volume, with a two layer panel sandwich, one of PCM and the other of a rigid polyurethane foam with a 4 cm thick metal cladding. A thermal analysis simulation, by means of DesignBuilder software, was conducted. To calculate the electric energy spent in a year to control air temperature in a range of 8- 22°C. The results were of 3590. 67 kWh/year for existing building and 2539.52 kWh/year for building with PCM, energy save of about 30%. A temperature decrease of about 3°C was measured inside the storage room without a cooling system during the hottest year period but the most important result was a thermal indoor air stabilisation in the storage room. This condition avoids a thermal fluctuation to the EVOO and it is the best storage condition.
Numerical simulations for the optimisation of ventilation system designed for wine cellars
Authors: Santolini Enrica , Barbaresi Alberto , Torreggiani Daniele , Tassinari Patrizia
Published: November 2019

The wine-ageing process is one of the most important phases of the wine production and it can be considerably affected by the micro-climatic conditions inside the ageing rooms. Underground wine cellars in small-medium wineries are designed with natural ventilation systems, able to maintain optimal indoor condition. However, critical factors emerge, such as mold growth or wine evapo-transpiration, where ventilation proved to be poorly designed, insufficient in the first case or excessive in the second one. The zones around the wooden barrels proved to be the most sensitive and problematic. These areas are the most investigated in terms of temperature and humidity values but surprisingly not in terms of air velocity. In this paper, a ventilation system has been designed and optimised to support the lack of ventilation, by means of computational fluid dynamics modelling. Eight configurations have been performed and analysed, identifying the best two according to the air velocity range. Specific parameters have been defined to appreciate the application limits of each configuration. These parameters can be used as reference for system design in similar studies and applications and can help scholars and professionals to identify the optimal configurations for the implementation and proper placement of the system inside a cellar.

Authors: Joubert Yvonne T. , Swart Christine
Published: November 2019

Orientation: This article focuses on the employees and managers’ experience of the effects of Neethling’s thinking style preference instrument on team performance.Research purpose: The purpose of this study was to compile a framework to apply Neethling’s thinking style preferences to team performance.Motivation for the study: Organisations today are aware that they need to increase quality, decrease costs, advance customer service, increase their adaptability to an increasingly competitive environment and decrease the time spent on creating new products. To realise these goals, organisations must convert their work teams into more cohesive and dedicated teams. No or limited research has been conducted on how the application of Neethling’s thinking style preferences may influence team performance.Research approach/design and method: A qualitative exploratory study was conducted with 19 participants working in the Financial and Insurance Department of a sales-driven organisation in Gauteng, South Africa. The data were collected by means of focus group and individual interviews.Main findings: The positive effects of the Neethling’s thinking style preferences on the team were that the participants understood people better, their conflict management skills increased, their self-awareness improved, the communication in the team increased and they experienced an increase in team cohesion. The negative experiences were task avoidance, labelling and wrong assessments of people, but the positive experiences exceeded the negative experiences. Due to the positive experiences, the organisation also benefitted in terms of improved customer service and increased productivity, which could lead to organisational success and a competitive advantage.Practical/managerial implications: When used in teamwork, the Neethling’s thinking style preference instrument shows positive outcomes regarding team performance.Contribution/value-add: The findings of this study contribute new knowledge regarding the application of Neethling’s thinking style preferences in team performance.

Published: November 2019

Abstract. This paper is about a study of diurnal tides on meteor wind observed simultaneously by two meteor radars sited on equatorial region. The radar are located in Santa Cruz (10.3° N, 85.6° W), Costa Rica (hereafter CR) and in São João do Cariri (7.4° S, 36.5° W), Brazil (hereafter CA). The distance between them is 5800 km. Harmonic analysis was used to get information of amplitude and phase (hour of peak amplitude) of diurnal, semidiurnal and terdiurnal tides between 82 and 98 km of height. The period of observation was from April 2005 to January 2006. The results were compared to GSWM00 model. In general, seasonal agreement between observation and model was satisfactory to zonal and meridional amplitudes. Values of zonal and meridional amplitudes from November to January to CR were very different of GSWM00. Peak of zonal amplitude (~ 25 m/s) to CR was observed in September and December between 90 and 94 km. On the other hand, meridional phase was excellent to both sites and vertical wavelength of 25 km was observed practically every month to CR and CA. The zonal phase presented some difficult to get vertical wavelength according to criteria adopted to calculate it. Considering diurnal zonal amplitude, when we compare CR and CA, we could expect a poor agreement of amplitude between them. That is normal if we believe that this is because the geographical location of both sites are completely different in terms of local climate even if they are close to the equator and effect of heat latent release could lead to different response at high altitudes.

E-Business, SMEs and Risks: Towards a Research Agenda
Authors: Sukumar Arun Chennakrishnan , Edgar David
Published: November 2019

Electronic business is a phenomenon that is becoming more widely researched and better understood. However, an extensive literature review has reviled limited understanding of the nature of e-business risk in organisations, and in particular in small to medium size organisations (SMEs). This paper explores the perceptions of five different stakeholder group respondents from across a range of SME organisations and members of e-business clubs. The results are intended to set an agenda for research into e-business risk and highlight that key themes revolve around strategic risk, customer risk, branding risk, security threats, legal and tax risks, leadership risks, outsourcing and dependency risk and technology risk. These themes are modelled to highlight theme dependencies and to assist in setting the research agenda.

Published: November 2019

Parental involvement is a key predictor of students’ success in academic and general life. Moreover, the integration of technology has had a massive influence on the learning process and in facilitating parents’ involvement. The current study aims to explore the role of parents in the achievements of English as a foreign language (EFL) learners via Edmodo, which is a platform consisting of three important main components. A descriptive method is used to conduct the research with a sample of 50 parents of female students at the intermediate stage of King Abdul Aziz private school, and using a questionnaire as an instrument. The results indicated a high level of parental involvement in supporting their daughters’ progress. Moreover, parents were pleased when the teachers kept them informed about their daughters’ progress in English. Communication with the school and supervision of homework had a positive effect on the quality of learning. The results revealed that parental involvement enhanced English language skills and increased learners’ motivation to work hard. In addition, the study discovers the positive perception of parents regarding the use of Edmodo.

Diálogo con jóvenes: voces, experiencias y narrativas sobre el suicidio
Authors: Chow Luis Carlos A. R.
Published: November 2019

En solo el año 2018, se contabilizaron a nivel mundial 800,000 muertes por suicidio. En América Latina el promedio de personas que cometen suicidio es 9.8 por cada 100,000 habitantes. El grupo etario en el que predomina este suceso se encuentra en un rango de 14 - 35 años. En Nicaragua las cifras de suicidios han tomado auge estrepitosamente, siendo el 2017 el año más alarmante con más de 300 casos registrados. Se han identificado las características del comportamiento suicida, habiendo predominancia en las zonas urbanas, entre edades de 12 a 35 años, entre ciudades del área Pacífico y Centro Norte y posteriormente al Caribe Sur. Entre los motivos identificados con los jóvenes que dialogué, destacan conflictos familiares, acoso escolar de tipo agresivo/psicológico, sistemas de creencias que los excluyen, discriminan y condenan; sistemas culturales de carácter patriarcal, procedimientos pedagógicos que pasaron por alto las situaciones específicas y no identificaron un patrón de conducta anormal, enfermedades mentales cuyos padecimientos se desconocían, imaginarios colectivos no compatibles con su identidad, y sobre todo, problemas de autoestima. El objetivo del artículo es acercar al lector sobre el fenómeno del suicidio desde las voces y narrativas de sus protagonistas, al igual que describir el comportamiento epidemiológico en la región latinoamericana y nacional.
Cultura de paz, pensar y repensar. Una respuesta al golpe
Authors: Rodríguez Corea Xavier Ernesto
Published: November 2019

La cultura de Paz, más que un concepto es una filosofía, una forma de ver el mundo y al otro ¿cómo concretamos esa visión en la vida cotidiana? , la cultura de paz puede ser entendida desde diversas posibilidades y por consiguiente se aplicaría a la vida misma de diversas formas. En este ensayo se busca reflexionar sobre este concepto, vital para Nicaragua luego del intento de golpe de estado fracasado y la necesidad de rematar cualquier asomo de fascismo, cada vez más popular entre algunos sectores como reacción al avance de los sectores populares en la patria grande. En un primer momento queremos abordar el contexto del golpe de estado en Nicaragua, luego reflexionar a modo de paréntesis, algunos elementos sobre la relación al devenir histórico del concepto de paz en diversas culturas y tiempos; finalmente regresar a Nicaragua a plantear algunos elementos de esta cultura de paz muy nuestra que estamos construyendo. Finalmente es importante dejar sentado que el escrito esta pensado desde la postura del intelectual orgánico (Gramsci) y huye de la posibilidad de analizar de forma neutral, muy de moda entre algunos académicos.
¿Cómo construimos un modelo de formación? El caso de la espiral 3D+
Authors: Ulloa Forero Luis Felipe
Published: November 2019

Este texto intenta relatar a los lectores que cuando hay ya un sentido que orienta la vida de un investigador, comunicador o educador, las opciones que toma en su campo responden a eso que ya trae, sin necesidad de hacerlo explícito. Los trayectos de vida de una persona visibilizan eso que da y eso que no da sentido a las acciones de una persona. De ahí que convertirlos en foco de estudio para sí mismos, es de interés, y ayuda a buscar coherencia entre su discurso y su acción. Partiendo de la experiencia de construcción de un modelo de formación, el autor propone a los lectores y lectoras convertir los propios trayectos profesionales en foco de estudio y compartirlos, explora el concepto de modelo, revisa las andanzas del autor en la construcción del modelo de formación en Espiral 3D+ (Hechos, momentos y trechos) para extraer aprendizajes, y reflexiones en el camino y relaciona la idea de Espiral con nuestras raíces.

Educação, contextos culturais e infância: diálogos com as produções sul-americanas
Authors: Voltarelli Monique Aparecida
Published: November 2019

A grande diversidade da América do Sul, em seus diversos países e diversas histórias, está mergulhada numa variedade de contextos que mescla linguagens, trajetórias políticas, econômicas, sociais e composições étnicas que perpassam a vida das crianças. Essa característica tem demandado esforços dos pesquisadores que focalizam as crianças como agentes sociais e produtoras de cultura, levando em consideração tais conceitos na compreensão da realidade sociocultural em que estão inseridas. A partir de uma investigação exploratória sobre os estudos e produções científicas da Sociologia da Infância na América do Sul em países hispano-falantes (VOLTARELLI, 2017), este artigo visa analisar as temáticas educacionais identificadas nas pesquisas com e sobre as crianças, considerando os contextos culturais, bem como apontar aspectos da educação nas produções dos países nos quais a presença do campo foi identificada com maior densidade. Aponta-se que os contextos culturais em que as crianças estão imersas, juntamente com as políticas sociais e educacionais direcionadas à infância, configuram as experiências nas instituições educativas, sendo importante considerar a diversidade e a multiplicidade das infâncias nos processos educativos.
O princípio responsabilidade e a educação: aportes freirianos para uma compreensão ecopedagógica da heurística do temor em Hans Jonas
Authors: Peroza Juliano
Published: November 2019

Este artigo apresenta uma reflexão sobre a ética da responsabilidade do filósofo alemão Hans Jonas, especificamente a partir da sua concepção de heurística do temor em diálogo com o pensamento de Paulo Freire. A reflexão objetiva compreender a expressão heurística do temor a fim de interpretar a contribuição do seu significado com algumas proposições pedagógicas para contribuir com as discussões sobre ética, responsabilidade e a ação educativa. A metodologia da abordagem é de cunho bibliográfico e hermenêutico. Discute-se que a educação pode assumir essa tarefa de produção intencional da representação dessa imagem do temor que ainda não foi experimentado, de modo que a mesma traduza em aspectos político-pedagógicos seus reais propósitos de problematizar conjunturas e conscientizar a partilha global da responsabilidade. Propõe-se, com base em Paulo Freire, uma educação conscientizadora, uma ecopedagogia para a cidadania planetária.
Usefulness of Soft Tissue Therapy in Patients with Shoulder Pain Syndrome
Authors: Brzozowski Arkadiusz , Chomiuk Tomasz , Lach Jacek , Mamcarz Artur
Published: November 2019

Background. Shoulder pain is among the most common musculoskeletal pain syndromes. This study aimed to compare the effectiveness of the worldwide renowned Kaltenborn and Evjenth manual therapy and the innovative concept of Fascial Distortion Model (FDM) in the treatment of patients suffering from shoulder pain.
Material and method. The study group consisted of 100 patients treated for shoulder pain (SP), who were randomly assigned to two groups: Group A, whose therapy involved FDM (51), and Group B, treated with Kaltenborn and Evjenth method (49). Exclusion criteria comprised age < 30 years, low threshold of sensitivity to pain, participation in another rehabilitation programme, uncontrolled arterial hypertension, neurological conditions associated with sensory impairment, connective tissue conditions and presence of ‘red flags’. The tools used in the study included a digital inclinometer to measure the range of joint mobility and a NeuroTrack device to assess neuromuscular conductivity. Statistical analysis used the non-parametric Mann-Whitney U test and non-parametric Wilcoxon signed rank test. The significance threshold was accepted as p ≤ 0.05.
Results. Both groups showed significant improvement (p<0.05) in the range of motion in the upper limb in all direc­tions (flexion, abduction and external rotation) and change in the function of the infraspinous muscle. The only significant difference between the groups was found for external rotation (p<0.05), with Group A displaying a superior range of motion.
Conclusions. 1. A single session of the Kaltenborn and Evjenth method and FDM in patients suffering from shoulder pain may increase their range of motion in the shoulder as well as improve the function of the infraspinous muscle. 2. Cur­rently there is insufficient evidence to warrant stronger recommendation of one of the study therapies over the other. 3. There is a need for further prospective randomised studies involving larger groups of patients and assessing long-term effec­tiveness of the therapies.
The Use of Cryotherapy in the Early Postoperative Period after Total Hip Arthroplasty
Authors: Okoro Tosan , Ibrahim Yousef , Mansour Nadia , Alderman Phillip , Evans Aled
Published: November 2019

Background. Recent evidence suggests that cryotherapy may be beneficial in reducing postoperative pain and blood loss in joint arthroplasty. The objective of this study was to review the use of cryotherapy in the early postoperative phase after total hip arthroplasty to assess the benefits in terms of pain relief and reduction in postoperative blood loss.
Material and methods. A prospective cohort study of the use of a cryotherapy device (Hilotherm) was performed in patients following total hip arthroplasty. The primary outcome measures were visual analogue score (VAS) for pain (at 24 and 48 hours postoperatively), and amount of postoperative blood loss, measured by change in haemoglobin (g/L). The secondary outcome measures were length of stay (days), duration of patient controlled analgesia (PCA) administered postoperatively (hours) and amount of analgesia used (mg) in the first 48 hours.
Results. 28 patients were recruited (n=13 Hilotherm; n= 15 non-Hilotherm). Hilotherm application reduced pain in the first 24 hours, non-significantly, (3.50±2.41 vs 4.90±2.95; p=0.185). This effect was not carried through at 48 hours postoperatively (5.68±1.94 vs 3.72±2.46; p=0.029). Hilotherm application significantly reduced postoperative blood loss (22.38±5.71 g/L vs 29.13±10.22 g/L; p=0.045). Hilotherm reduced length of stay by almost 1 day; however, this was not statistically significant (4.46±2.33 vs 5.20±3.55; p=0.528). There was no difference in the length of time PCA was administered (22.30±0.75 vs 22.02±3.26; p=0.763). Patients in the non-Hilotherm group required more paracetamol on average (p=0.001).
Conclusions. 1. Hilotherm application does not appear to significantly reduce pain postoperatively but re­sults in less postoperative blood loss. 2. There may be a role for the continued use of cryotherapy in the early period of rehabilitation following total hip arthroplasty, as it appears to result in more rapid ambulatory rehabilitation in patients, resulting in reduced length of stay.

Die Regulierung des Peer-to-Peer-Lending in Deutschland
Authors: Eberle Nicolas
Published: November 2019

Peer-to-peer lending, in its original form direct loan agreements between consumers, facilitated through an Internet platform, is the economically most relevant form of online alternative finance. This book features a comprehensive analysis of the regulatory framework applicable to peer-to-peer lending in Germany, including its consequences for entrepreneurial practice, consumer access to debt financing and its effects on competition for innovative, technology-driven business models in Germany. The author describes the different variants of peer-to-peer lending in the US and the United Kingdom from a factual and legal perspective, and explains their respective approaches to regulation. He subsequently develops suggestions for improvements to the German regulatory framework and the administrative practices of supervisory authorities regarding innovative, technology-driven businesses.
Vereinbarte Mitbestimmung und Aktionärsbeteiligung in der SE
Authors: Kleissler Max
Published: November 2019

The European Company (SE) is characterised by negotiable co-determination, which makes it attractive from the point of view of German companies in particular, despite incomplete legal regulations. However, the law assigns the negotiations on co-determination on the part of the companies exclusively to the so-called management bodies, although these are not only concerned with co-determination at an operational level, but also within the supervisory board. On the other hand, the law is extremely rudimentary on the participation of shareholders. It is precisely this shareholder participation that is the subject of the investigation, including its supplementation to a coherent system. Not only the formation procedure, but also the possibilities of participation are examined if there are renegotiations on the previously negotiated co-determination regime. Finally, the work deals with proposals to improve shareholder participation de lege ferenda.

Notas sobre o teatro de revista
Authors: Cordeiro Volmir Gionei , Collaço Vera Regina Martins
Published: November 2019

Uma Revista acomoda uma pertinência, uma insistência. Nela habitam pontos geradores de ação que convergem para impulsionar seu desenrolar. É dentro deste aspecto que o presente trabalho se viabiliza e propõe suscitar reflexão sobre tal modo de se fazer teatro. A idéia reside em reconhecer a estrutura convencional do Teatro de Revista a partir do texto de Nicolau Nagib Nahas, “A Ilha dos Casos Raros”(1927), detendo-se na figura central e sua busca, percebendo como se desloca a ação a partir do interesse de determinado personagem; se esta palavra se permite e como se vê tal convenção no Teatro de Revista. O modo como se organizam os quadros e que função exercem no todo da peça em questão e no teatro em discussão; a temática eminente e suas conexões com o ambiente na qual se inspira a Revista e ainda, o ator que a fabrica de acordo com as necessidades que a mesma lhe confere, fazendo dela uma arte popular e divertida, são abordagens oportunas no corpo deste estudo. O ponto de investigação do presente trabalho localiza-se na receita dada por Veneziano (1991) quanto à constituição dramatúrgica da revista, que segundo ela, era simples e se dava pela “busca ou perseguição á alguém ou alguma coisa, os personagens centrais caminhavam, corriam, andavam, procuravam ou fugiam. Havia continuamente alguém que perseguia alguém e alguém que escapava por um triz” (1991:88). Esta seria a organização-base da revista de ano. É por isso que no início apontamos que uma Revista adota uma insistência, porque é pela persistência da figura central, que emergem os quadros episódios, ou intermédios que vão criticar de forma mais concreta, ainda que não menos alusiva, a realidade presente.

Authors: Lampert Jociele
Published: November 2019

Este estudo objetiva averiguar alguns embates na formação docente em Artes Visuais partindo das tensões entre a cultura visual, as Artes Visuais e a Educação (enquanto formação docente). Desta forma, ampara-se em uma reflexão teórica da educação para a compreensão crítica da arte e no que confere a contemporaneidade aborda-se Debord (1997). A moda é um ponto articulador na cultura visual e também se constitui como elemento agenciador dos estudos culturais na contemporaneidade. Assim, a abordagem do sistema estético da moda em contra ponto com as Artes Visuais, pode sugerir a construção de uma reflexão crítica sobre a sociedade em que vivemos.

Império: uma civilização nos trópicos
Authors: Sant’Anna Mara Rúbia
Published: November 2019

O volume 2 da pesquisa Brasil por suas aparências ocupa-se da discussão das relações entre aparência, poder e identidade nacional desenvolvidas entre o período histórico, convencionalmente chamado, Brasil-Império. As conclusões preliminares evidenciam que a instituição da independência política da colônia portuguesa na América não representou rompimento dos modelos de aparências e nem reformulou as elites que conduziam a formulação de uma noção de identidade brasileira. A figura do imperador D. Pedro II foi de vital importância na catalisação dos anseios de parecer européia da elite imperial.

Aplicación de un modelo de analítica de texto para la detección y clasificación automática de tendencias de investigación en e-Learning (caso UOC)
Authors: López Ruiz José , Garcia Brustenga Guillem
Published: November 2019

La revisión de literatura científica es una tarea habitual entre investigadores que deseen detectar las tendencias que están influyendo como palancas de cambio en la evolución de una disciplina o ámbito concreto de investigación. Obtener tal conocimiento requiere de pesadas y repetitivas tareas de extracción, análisis, síntesis y clasificación de cientos, y en algunos casos miles, de referencias bibliográficas. Estas primeras fases requieren de un gran esfuerzo por parte del equipo de analistas para recoger y ordenar resultados de la evidencia científica en los que basar sus conclusiones, dedicación que puede incrementarse en función del zoom de cada búsqueda. En su facultad de observación del "mapamundi" del conocimiento para detectar y reflexionar acerca de las tendencias y acontecimientos que están transformando la educación superior en línea en el mundo, el eLC integra en su actividad tales tareas de revisión y prospectiva documental. Con la intención de facilitar el camino hacia el descubrimiento y análisis de la información relevante objetivo de cada estudio, el centro ha pilotado un proyecto consistente en automatizar parte de este proceso de revisión basándose en el uso de tecnologías de analítica y minería de texto.

Decomposed
Authors: Devine Kyle
Published: November 2019

The hidden material histories of music.

Music is seen as the most immaterial of the arts, and recorded music as a progress of dematerialization—an evolution from physical discs to invisible digits. In Decomposed, Kyle Devine offers another perspective. He shows that recorded music has always been a significant exploiter of both natural and human resources, and that its reliance on these resources is more problematic today than ever before. Devine uncovers the hidden history of recorded music—what recordings are made of and what happens to them when they are disposed of.

Devine's story focuses on three forms of materiality. Before 1950, 78 rpm records were made of shellac, a bug-based resin. Between 1950 and 2000, formats such as LPs, cassettes, and CDs were all made of petroleum-based plastic. Today, recordings exist as data-based audio files. Devine describes the people who harvest and process these materials, from women and children in the Global South to scientists and industrialists in the Global North. He reminds us that vinyl records are oil products, and that the so-called vinyl revival is part of petrocapitalism. The supposed immateriality of music as data is belied by the energy required to power the internet and the devices required to access music online. We tend to think of the recordings we buy as finished products. Devine offers an essential backstory. He reveals how a range of apparently peripheral people and processes are actually central to what music is, how it works, and why it matters.
Extraterrestrial Languages
Authors: Oberhaus Daniel
Published: November 2019

If we send a message into space, will extraterrestrial beings receive it? Will they understand?

The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In this book, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings' various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions: If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we) speak? Is there not only a universal grammar (as Noam Chomsky has posited), but also a grammar of the universe?

Oberhaus describes, among other things, a late-nineteenth-century idea to communicate with Martians via Morse code and mirrors; the emergence in the twentieth century of SETI (the search for extraterrestrial intelligence), CETI (communication with extraterrestrial intelligence), and finally METI (messaging extraterrestrial intelligence); the one-way space voyage of Ella, an artificial intelligence agent that can play cards, tell fortunes, and recite poetry; and the launching of a theremin concert for aliens. He considers media used in attempts at extraterrestrial communication, from microwave systems to plaques on spacecrafts to formal logic, and discusses attempts to formulate a language for our message, including the Astraglossa and two generations of Lincos (lingua cosmica).

The chosen medium for interstellar communication reveals much about the technological sophistication of the civilization that sends it, Oberhaus observes, but even more interesting is the information embedded in the message itself. In Extraterrestrial Languages, he considers how philosophy, linguistics, mathematics, science, and art have informed the design or limited the effectiveness of our interstellar messaging.
