Microwave-promoted One-pot Synthesis of Imidazo[1,2-a]pyridines in Lemon Juice
Authors: Saeed Hani Yeslam , Wagare Devendra S. , Shaikh Mujahed , Durrani Ayesha 
Published: October 2020

Objective:
A simple and highly efficient microwave-promoted procedure for the synthesis
of imidazo[1,2-a]pyridine derivatives from the reaction of aromatic ketones, N-bromosuccinimide,
and 2-aminopyridines in lemon juice was designed. The main advantages of this protocol,
such as clean reaction profile, mild reaction condition, high yield, and minimum reaction time,
were compared to other previously developed methods.

Method:
A mixture of aromatic ketones (1a-m) (0.005 m), N-bromosuccinimide (NBS) (0.005 m),
and lemon juice (10 ml) was irradiated by microwave at 400-watt power at 85°C, and the formation
of α- bromoketones was monitored by Thin Layer Chromatography (TLC). After completion
of α-bromination, 2-aminopyridines (0.005 m) was added to the reaction mixture and it was further
irradiated at the same reaction condition. After completion of the reaction, the reaction mass was
poured in ice-cold water, the solid product obtained was filtered, washed with cold water, and recrystallized
from aqueous ethanol.

Result:
In the present investigation, we have developed an environmentally benign, easy, and highly
efficient one-pot procedure for the synthesis of 2-phenylimidazo [1, 2-a] pyridines from the reaction
of aromatic ketones, N-bromosuccinimide, and 2-aminopyridines in lemon juice as a natural
acid catalyst and solvent under microwave irradiation. This new protocol offers very attractive features
such as minimum reaction time, clean reaction profile, mild reaction condition, and green aspects
such as avoid poisonous catalyst, hazardous solvents, ease of the work-up procedure, and
higher yield.

Conclusion:
In the present investigation, we have developed an environmentally benign, easy, and
highly efficient one-pot procedure for the synthesis of 2-phenylimidazo [1, 2-a] pyridines from the
reaction of aromatic ketones, N-bromosuccinimide, and 2-aminopyridines in lemon juice as a natural
acid catalyst and solvent under microwave irradiation. This new protocol offers very attractive
features such as minimum reaction time, clean reaction profile, mild reaction condition, and green
aspects such as no need for a poisonous catalyst and hazardous solvents, ease of work-up procedure,
and higher yield.
The Role of Technology and the Continuum of Care for Youth Suicidality: Systematic Review
Authors: Szlyk Hannah , Tan Jia 
Published: October 2020

Background
Youth suicide is a global public health issue, and using technology is one strategy to increase participation in preventive interventions. However, there is minimal knowledge on how technology-enhanced interventions for youth correspond to the stages of care, from illness or risk recognition to treatment follow-up.

Objective
This systematic review aims to examine the efficacy of technology-enhanced youth suicide prevention and interventions across the continuum of care.

Methods
Four electronic databases were searched up to spring 2019 for youth suicide preventive interventions that used technology. The review was not restricted by study design and eligible studies could report outcomes on suicidality or related behaviors, such as formal treatment initiation. An adapted version of the Methodological Quality Ratings Scale was used to assess study quality.

Results
A total of 26 studies were identified. The findings support the emerging efficacy of technology-enhanced interventions, including a decline in suicidality and an increase in proactive behaviors. However, evidence suggests that there are gaps in the continuum of care and recent study samples do not represent the diverse identities of vulnerable youth.

Conclusions
The majority of identified studies were conducted in school settings and were universal interventions that aligned with the illness and risk recognition and help-seeking stages of the continuum of care. This field could be strengthened by having future studies target the stages of assessment and treatment initiation, include diverse youth demographics, and examine the varying roles of providers and technological components in emerging interventions.
Capturing, Exploring and Sharing People’s Emotional Bond with Places in the City using Emotion Maps
Authors: Stals Shenando , Smyth Michael , Mival Oli 
Published: October 2020

With the vision of ubiquitous computing becoming increasingly realized through smart city solutions, the proliferation of smartphones and smartwatches, and the rise of the quantified-self movement, a new technological layer is being added to the urban environment. This technological layer offers the possibility to capture, track, measure, visualize, and augment our experience of the urban environment. But to that end, there is a growing need to better understand the triangular relationship between person, place, and technology.
Urban HCI studies are increasingly focusing on emotion and affect to create a better understanding of people’s experience of the city, and to investigate how technology could potentially play a role in augmenting this urban lived experience. Artist Christian Nold for example, used wearable technology to measure people's arousal levels as they walked freely through the urban environment, identifying locations in the city that evoked an emotional response from people. After these walks, people’s arousal levels were superimposed on a map of the city and participants were asked to interpret their own data, resulting in aggregated, fully annotated, and beautifully visualized emotion maps of the city.
Based on a systematic review of emotions maps in existing literature, and our own work which seeks to understand how people’s experiences of places in the urban environment that are meaningful to them on a personal level, for example the place where they have met their partner, could potentially inform the design of future technological devices and services, this journal paper discusses the strengths, limitations and potential of capturing, representing, exploring and sharing this personal, geo-located emotion data with other people using emotion maps. Although our analysis seems to indicate that emotion maps in their current form are only of limited efficacy in accurately capturing, representing and communicating the profound, complex emotional bond that people have with personally meaningful places in the city, there appears to be potential for the use of emotion maps as a provocation in a speculative design approach.
Composer-composer collaboration and the difficulty of intradisciplinarity
Authors: Scheuregger Martin , Efthymiou Litha 
Published: October 2020

Research and practice involving parties from different disciplines is of increasing importance in many fields. In the arts, this has manifested itself in both increasing attention on established collaborative partnerships – composers, for example, collaborating with writers, choreographers and directors – and a move towards more overtly cross-, multi-, inter- and/or trans-disciplinary forms of working – a composer working with a physicist, philosopher or psychologist. Composer-composer partnerships are far less common, meaning intradisciplinary collaboration is little explored in relation to practice research in music.
This article takes the collaborative music theatre composition I only know I am (2019) created by the authors – Litha Eftythmiou and Martin Scheuregger – as a case study, outlining the issues and opportunities that arise through combining two compositional practices in an effort to create a single artistic output. Ways in which the composers managed this process are detailed in the context of communication, technology, and the issue of tacit knowledge (of both individual compositional process and the working of intradisciplinary collaboration). In particular, reflections on their experience during a week-long residency, in which they collaborated on a single musical work, is discussed in order to understand to what extent two aesthetic approaches can be reconciled to create work satisfactory to both parties.
Notions of composition as an inherently collaborative process are used to contextualise the means by which composer-composer collaborations might be understood. The authors reflect on an understanding of intradisciplinarity in the context of their practice as composers in order to draw conclusions that will allow them, and others, to approach composer-composer collaboration in an informed manner.
Embodied Complexity in Choral Singing
Authors: Galbreath Daniel 
Published: October 2020

Amateur musical ensembles draw participants from widely varying disciplines into shared artistic activity in a way that few other artforms do; in particular, choral music, in which bodies both create and directly receive sound, raises profound questions of how performers’ uniquely embodied creative approaches interact. Amateur choral singing therefore offers a lens into how musical creativity is distributed among, and emergent from, a diverse group of individuals. This article explores how the performance of indeterminate and improvisatory choral works offers a powerful example of this distributed creative agency via a network of sounding bodies.
This article centres on a case study (March–October 2017) involving three British amateur choirs in the performance of improvisatory choral scores by Kerry Andrew (2005) and Cornelius Cardew (1968–70). Complexity Theory (Davis and Sumara 2006) offers a useful framework for understanding how creative impulses and constructions interact; both the vocal expression and corporeal receipt of these creative ideas occurs in an embodied way, drawing on dance and embodiment theory (Sheets-Johnstone 2009, Downey 2002). The research process and qualitative-data-processing methodology (Charmaz 2014) of the case study are described, before findings are laid out with a view to how they point towards ideas of embodied, complex interaction. These findings offer an important, and hitherto unexplored, view into how Complexity Theory (a common theoretical framework in other fields across the sciences and humanities) might usefully describe musical performance. In transcending attempts to atomise ensemble interaction according to shared intellectual knowledge and verbal communication, the complex, embodied interaction of diverse singers, through the physical connection of sound, might involve those singers in the distributed authorship of a musical work.
Presentación

Una vez más los gobiernos de los países más contaminantes, las corporaciones del petróleo, el gas y el plástico, los bancos y fondos de inversión con negocios fósiles, las autoridades de organismos internacionales y los “economistas” si es que pueden merecer ese nombre nos han condenado a enfrentar un mundo en llamas. Desde abril de 1995, cuando se realizó la primera Conferencia de las Partes (COP) en Berlín, Alemania, todas las reuniones han “fallado” en establecer mecanismos vinculantes obligatorios para reducir drásticamente las emisiones de gases de efecto invernadero (GEI); y lo mismo ha sucedido recientemente en diciembre de 2019, durante la COP25 realizada en Madrid, España. Frente a la catástrofe climática, los “tomadores de decisiones” respondieron con tecnicismos y pasividad, aplazando un año más la aplicación de soluciones estructurales. Con éste ¡ya son 25 años perdidos en “negociaciones” internacionales! (Harvey, 2019).
Capitalismo omnicida y “nacional-trumpismo”: impulso bélico-industrial, bancario y financiero hacia el colapso bio-climático
Authors: Saxe-Fernández John 
Published: October 2020

Este trabajo es una aproximación al encadenamiento estructural de suicidio, genocidio y omnicidio colectivos, presente en la fusión entre una mayor movilización bélico-industrial para una Tercera Guerra Mundial a base de combustibles fósiles y explosivos nucleares, y la aceleración bancario-financiera del colapso bio-climático capitalogénico, vía el incremento anual de la inversión mundial en el sector de los combustibles fósiles. El omnicidio se asocia al negacionismo climático del “nacional-trumpismo”, como una excreción de la crisis del capital monopólico-financiero que se gesta en el epicentro capitalista en crisis hegemónica, y que tiene manifestaciones devastadoras para las naciones de América Latina y para el planeta entero. Por su peligrosidad, resaltan los proyectos de fracking propuestos hasta ahora para ser desplegados en México.

Published: October 2020

Resumen: Este artículo recoge los resultados de una tesis doctoral realizada en el período 2013-2018, en donde se analiza la configuración del circuito de rock de la ciudad de La Plata. Retomando algunos resultados, aquí analizaremos los itinerarios de un conjunto de músicos/as integrantes del circuito, enfocándonos en sus trayectorias, en los trayectos que realizan en el espacio urbano y en las lógicas que organizan sus andares. Sostenemos como hipótesis que son las trayectorias de los actores las que modulan los trayectos que realizan, así como son esos recorridos espaciales los que poseen un carácter performativo sobre sus biografías. La estrategia metodológica será de tipo cualitativa, utilizando diversas herramientas de producción de datos, en donde se destaca la técnica de sombreo (Jirón, 2012). Asimismo, este artículo también brinda una reflexión sobre herramientas metodológicas para estudiar prácticas artísticas en la ciudad y su reciprocidad: el modo en que la ciudad condiciona las prácticas, las formas en que estas prácticas producen ciudad.Palabras Clave: Circuito.

This article collects the results of a doctoral thesis carried out in the period 2013-2018, where the configuration of the circuit of rock in La Plata city. Returning to some results, here we will analyze the itineraries of a group of musicians who are members of the circuit, focusing on their trajectories, the journeys they make in the urban space and the logics that organize their gait. We hypothesize that it’s the trajectories of the actors that modulate the paths they make, as well as those spatial paths that have a performative character about their biographies. The methodological strategy will be qualitative, using various data production tools, where the shadow (Jirón, 2012) stands out as a technique.Likewise, this article also provides a reflection on methodological tools to study artistic practices in the city and their reciprocity: the way the city conditions practices, the ways in which these practices produce city.Keywords: Circuit.

Published: October 2020

Resumo: Buscamos compreender os dilemas em torno da ação de uma artista que pixou a palavra “NAUFRÁGIO” no corpo sintético de uma das vacas da CowParade Belém 400 anos, evento internacional de arte na rua que aconteceu na capital do estado do Pará, no ano de 2016. A pixação enquanto uma agência de significativa inserção ético-estética conectou dois episódios de grande impacto no contexto paraense: 1. O episódio envolvendo “bovinos” chamado CowParade, no qual 50 vacas de fibra de vidro foram customizadas por artistas locais e expostas na cidade. 2. O naufrágio de um navio carregado de bois vivos no porto de Vila do Conde a poucos quilômetros de Belém, que matou milhares de bovinos (resultando em 2.450 toneladas de carcaças) num grande desastre socioambiental com repercussões econômicas sérias para as comunidades locais, já que os resíduos do desastre (carcaças e óleo) confundem as ordens do limpo e do sujo, do lixo e do asseio nas paisagens, impossibilitando o curso normal da vida no mundo urbano.
