Today's Performance Research Articles

On the Problem of Collective Identity in Beijing's East Village

Since its emergence in China in the 1980s, performance art has been one of the most pioneering art forms in modern art. In the early days, the group behavior of the artists in Dongcun, Beijing, China, had a strong impact on today's performance art form. In this paper, taking "Adding One Meter to the Nameless Mountain" as an example, the author gives some thoughts on the collective identity of Beijing Dongcun's art, and gives a rough explanation from the perspectives of the background of the artwork, the process of its creation, and the subsequent derivation of the artwork.

Critical life cycle assessment of the innovative passive nZEB building concept ‘be 2226’ in view of net-zero carbon targets

Buildings constructed today need to be nearly-zero energy/emission buildings (nZEB) during operation. Amongst strategies to meet today's nZEB performance requirements are passive building concepts. However, it is unclear to which degree such concepts aid buildings to achieve net-zero carbon targets. To address this research gap, we conduct a life cycle assessment (LCA) of the passive nZEB concept '2226' based on its original prototype office building in Austria. We deploy a quantity takeoff and the measured end-energy demand to calculate the embodied and operational GHG emissions. In line with the recent draft of the building LCA standard EN15978, we split energy usage into building-integrated and non-integrated systems. Embodied GHG emissions make up about a third of the total life cycle GHG emissions (33%), and operational energy use accounts for two-thirds (67%) of the life cycle GHG emissions, considering the current Austrian energy grid mix. The contextualisation with the literature shows better performance in comparison to existing building standards, yet no reduction is achieved compared to buildings with similar nZEB ambitions. The measured end-energy analysis shows that two-thirds (68%) of the operational GHG emissions are allocated to building-integrated systems, i.e., those regulated by today's EU Energy Performance of Buildings Directive. Almost a third (30%) of the operational GHG emissions can be allocated to non-integrated systems, currently being reported as optional in the latest draft of the standard EN15978. We recommend extending the system boundary of building LCA including these end-energy uses by non-integrated systems in future building regulation and building LCA practice. • LCA of an innovative passive nZEB office building in Austria. • Embodied GHG emissions from BIM-based quantity take off; operational GHG emissions from measured data. • Allocation of operational GHG emissionsin distinct sub-modules B6.1, B6.2 and B6.3 • 30% of operational GHG emissions allocated to non-building integrated systems. • Reflections on other studies and critical discussion in relation to net-zero carbon targets.

Evaluation of the physical and rheology properties of rubberized asphalt cement

Asphalt cement is a viscoelastic substance that operates like an elastic solid at low service temperatures or under rapid loading. Whenever loaded slowly or at high temperatures, it behaves like a viscous liquid. This classic duality necessitates enhancing the efficiency of an asphalt binder to decrease stress cracking at cold temperatures (fatigue) and plastic deformation at hot temperatures (rutting). The use of polymer-modified asphalt binder is one solution for satisfying today's pavement performance standards. The purpose of this study was to determine the impact of asphalt cement modifiers on the physical and rheological properties of asphalt cement. This study used asphalt cement with a penetration grade of 40-50, modified with styrene-butadiene rubber (SBR) at four different levels of modification, specifically 0%, 2%, 4%, and 6% by weight of asphalt cement. Depending on Rotational viscosity and dynamic shear rheometer, and the traditional test. The mixes modified with SBR polymer showed enhanced physical and rheology characteristics, with decreased penetration and ductility and increased viscosity and softening point, as well as a lower rutting factor, indicating an increase in rutting resistance, according to the experimental data. The performance grade for original asphalt cement was 64-16, and for SBR at 2% additive, the original PG was improved to PG70-16. Adding 4% additive to asphalt cement improved the performance grade to PG76-16, and using 6% increased the performance grade to PG82-16.

A Blockchain Based Lifelong Learning Platform: The Smart University

According to today's education system, the content, applicability, quality and performance measurement criteria of the courses may vary according to countries, educational institutions and educators. Because of incorrect performance measurement, hidden skills disappear before they appear. Thanks to the graduation diploma it is observed that people with less than professional knowledge and skills come to better places than those who are more knowledgeable and skilled. In addition, due to the lack of a proper training plan according to the target learning community, boredom and financial problems may arise due to long periods of education. In this study, while trying to avoid material and temporal problems, a blockchain-based lifelong learning platform whose content, processing, reliability, decentralized, open to continuous and rapid accessibility, and evaluation criteria and method is completely objective is proposed. Thanks to this platform, the diplomas to be received by the students who have successfully passed the end-of-education exams will be time-stamped, immutable, safe and traceable. At the same time, all these documents, storage of training contents, diplomas, certificates, post-training exams and all related files , will be kept accessible, secure and immutable thanks to IPFS, the Inter Planetary File System. Achievements, employer and employee pools to be created according to the achievements, and a recruitment contract to be realized will be controlled by smart contracts and absolute reliability and objectivity will be ensured. All these concepts will be made available through a decentralized application (DApp) which will run on a private blockchain network that requires a partial permission to be established.

National image in ukrainian opera: scientific aspect of directing interpretations

The aim of the study is to determine the director's approaches to the creation of national images in Ukrainian opera on the basis of social origin, age, gender, peculiarities of living conditions in a particular environment, the characteristics of the characters. The object of research was M. Lysenko's opera "May Night, or Drowned" in the conceptual design of the composer and his various directorial incarnations. The methodology of research of the chosen problems uses the system-analytical and typological method. Their application contributes to a comprehensive approach in the study of factors shaping the formation of national characteristics of the Ukrainian ethnos, in identifying its individual characteristics and necessary features, their manifestations in creating an artistic image of the character. The relevance of the study is due to the need for historically reliable embodiment of the images of the Ukrainians in today's opera performances. Today's Ukrainian musical theatre, which is developing in the direction of globalization, does not avoid the positive and negative consequen-ces of the so-called "theatrical integration", which, in turn, leads to a conditional image of the Ukrainians, avoiding a historically accurate view of social status, coverage, clothing, character and so on. Often the director's interpretation of the images of Ukrainian characters is simplified, and sometimes distorted due to self-identity. The formation of the Ukrainian ethnos took place under the influence of certain factors that influenced the formation of its characteristics, features of life and customs, traditions, customs, rituals, which requires scientific understanding to accurately reflect these aspects in operas on national themes. Findings and conclusions. The Ukrainian theatre did not escape the influence of globalization and integration processes, which had both positive and negative consequences. The positive ones include allowing Ukrainian artists to join joint international opera’s projects, to solve joint problematic opera`s regimes, to exchange creative achievements and discoveries, and so on. To the negative ones - the mechanical transfer of foreign directing experience, avoiding its rethinking, on domestic soil without taking into account the peculiarities of the mental perception of the Ukrainian ethnic group of foreign traditions, way of life, means of communication and more. The analysis of the scientific work on the selected issues allows to state the fragmentary nature of research in the stage incarnations of artistic images of Ukrainians in the national opera. Solving the national image in Ukrainian opera requires a comprehensive cross-sectoral approach in determining the characteristics of the characters through the prism of ethnic identity, age, gender, social status, which affects their directorial interpretations. The director must conduct research work to determine the factors influencing the formation of the characteristics of a particular character in order to historically and reliably address the image of the Ukrainian in the opera. Isolation of different archetypes of the Ukrainian ethnos allows to create a more complete psychological portrait of the opera character, which, acting in the "proposed circumstances", will be historically authentic, as in the stage image of life, rituals and ceremonies with appropriate selection of means of communication. social status, age, gender and other characteristics of the actors. Prospects for further research are seen in the in-depth study and creation of a historically authentic national image of the character in the musical and theatrical arts.

Education Values in Wayang Wong Innovative Arts ‘Cupu Manik Astagina’

This article was compiled based on the results of research aimed at being able to understand the values of education in the innovative art performance of Wayang Wong Cupu Manik Astagina. This research was conducted because there was an imbalance in the field. Generally, in Bali, the Wayang Wong performance is only played by a group of parents. Unlike the case with the Cupu Manik Astagina Innovative Wayang Wong performance. Although the innovative Wayang Wong performance art is also presented in the form of drama children and young people in Bali still enjoy this show. Questions: (1) Why do children and young people in Bali enjoy the Wayang Wong Innovative Cupu Manik Astagina performance?; (2) what educational values are found in this performing art?; (3) how do children and adolescents in Bali interpret this innovative Wayang Wong performance? This paper is the result of qualitative research with a cultural studies approach. Data collection was carried out through document studies, observations of Wayang Wong performances, and in-depth interviews with 10 informants from the actors of puppet art, observers and the community of puppet art lovers in Bali.

Serious Gaming as an Additional Learning Tool for Medical Education

Computer-based learning methodologies have become more prevalent in the last decade. Web-based serious gaming and virtual patients are novel in medical education, which has the potential to become important tools to improve today's medical students' knowledge and performance. A total of 81 medical students participated in our study. They were either assigned to an intervention group or a control group. The intervention group completed a serious game module designed for Basic Life Support education. The control group received a theoretical lecture on the same content. On the next day, both groups received simulation-based hands-on training for BLS using the same criteria. All students were assessed with an Objective Structured Clinical Examination (OSCE) the following week. There was no difference between the intervention group using a web-based serious game module for BLS and the control group that received a standard theoretical lecture from the faculty. Computer-based interactive serious games seem to present a favourable additional tool for medical education. OSCE results imply, that the use of serious games as a self-learning strategy can be as useful as theoretical lectures; which means that it is saving the time of learners and educators.

High temperature superconductor cables for EU-DEMO TF-magnets

Actual progress of High Temperature Superconductor (HTS) REBCO tapes show an enormous increase of critical current density especially at highest field. These results offer new possibilities for the application of REBCO for large fusion magnets with a magnetic field well above 13T at the conductor and a large temperature margin >10K. In parallel promising new proposals for the formation of high current HTS fusion conductors from these REBCO tapes are emerging, promising the applicability for fusion magnets, e.g. for a TF magnet of an European DEMO.The actual progress of REBCO tapes and several promising HTS fusion cable proposals will be highlighted which open the path to future high field HTS magnets for fusion. Using such REBCO tape data, calculations and modeling of a TF coil for an EU-DEMO based on the PROCESS code will be presented, showing that with today's HTS performance an EU-DEMO TF conductor is feasible, which can be operated at 4.5K with a maximum field at the conductor of approximately 13.3T (magnetic field at the plasma center approximately 6.8T) with a temperature margin of approximately 12K.Special attention will be given to a new stacked HTS conductor fabrication technique proposed by KIT which is optimized for long length production of HTS strands with high engineering current density. Due to the cross shape of the soldered superconductor stacked, this type of strand is called HTS CrossConductor or HTS CroCo. The implementation of the simple, reliable and easily scalable fabrication routine will be outlined. Measurement results of first samples show the expected critical current calculated from the individual tape opening the way to a compact kA-class HTS strands. These HTS strands can be used as a basis to build a fusion cable for a TF-coil for an EU-DEMO.

Performance Management: Embracing Complexity, Evading Reductionism, and Moving to Outcome-Based Approaches

Adler et al. (2016) open with a summary of the business case driving our field to change and close by providing principles for accomplishing that change, where they conclude that “there is no right answer to the ratings question” (p. 244). Lying between the opening and closing sections is a series of arguments for and against today's performance rating status quo, arguments illustrating just what happens when too many years are spent seeking answers along too narrow a path. In this commentary, we provide additional support for the strategy- and outcome-driven approach to performance management advocated in the article. In addition, we offer ideas for what has contributed to getting us and keeping us where we are. Unless we understand what has driven performance ratings research and practice to be the object of an intense and lengthy debate, these same forces may well drive us to carry out years-long experiments of questionable value along similarly narrow paths. We want to offer our views on how to foster outcome-based practice more broadly.

From Jim Crow to Jay-Z: Race, Rap, and the Performance of Masculinity by Miles White (review)

IDENTITIES Jim Crow to Jay-Z: Race, Rap, and the Performance of Masculinity. By Miles White. (African American Music in Global Perspective.) Urbana: University of Illinois Press, 2011. [163 p. ISBN 9780252036620 (hardcover), $60; ISBN 9780252078323 (paperback), $22.] Appendix, bibliography, index.In Jim Crow to Jay-Z: Race, Rap, and the Performance of Masculinity, Miles White traces the ways in which racial masquerade has proven central to the development of working-class masculinities from nineteenth-century blackface minstrelsy through today's performances of hip-hop. Establishing the contradictory ways that American minstrelsy objectified, fetishized, and commodified representations of in the first chapters, White's body-centered text then examines how hip-hop performance has helped to articulate new models of self and for youth and for white-and notably, for better and for worse (p. 3). Building on the foundational work of Eric Lott's Love and Theft: Blackface Minstrelsy and the American Working Class (New York: Lexington Books, 1992), he examines the profound consequences of minstrelsy on subsequent representations of African-American men, arguing that tropes of the brute reached an apotheosis with hip-hop culture and rap music beginning in the 1980s (p. 4). While the stoic hardness of hip-hop artists after Run-D.M.C. provided appealing images of power and self-reliance to young men, White also stresses how hiphop performance nonetheless retained notions of deviant male subjectivity as its most defining subtext, especially in the racial play of white hip-hop artists (p. 3).The pivotal turn, according to White, is a move from hard to hardcore hip-hop after N.W.A. stories of inner-city violence a commercial success (ostensibly an argument about the shiftfrom nascent gangsta rap to commercial gangsterized rap). Extending the frame of John W. Roberts's From Trickster to Bad Man (from The Black Folk Hero in Slavery and Freedom [Philadelphia: University of Pennsyl vania Press, 1989]), the author examines the ways that hip-hop eschewed the trope of the bad man folk hero for the self-interested bad nigger stereotype abhorred by whites and blacks alike. Thus, argues White, N.W.A. reformulated minstrelsy's black brute as rapper, and transformed males from the 'hood into totemic performers of a powerful masculine authenticity and identity at a time in which there appeared to be few real men left (p. 64).In the first three chapters White's book really sings. His reading of racial masquerade and its centrality to the formation of American masculinities is crafted with nuance and rife with searing insights on performances of blackness in popular music. Chapter 1, and Act: American Popular Music and the Absent Black Presence, tracks the ways that technologies from burnt cork and sheet music to grease paint and recording technologies made possible a distancing of music from its socio-cultural origins and opened the floodgates for new racial commodities (p. 9). (Each chapter title riffs on titles of influential books, here on Ralph Ellison's classic collection Shadow and Act [New York: Vintage International, 1953], which contains the relevant essay Change the Joke and Slip the Yoke.) Especially instructive is the author's explanation of how the ideas of a uniquely American popular culture and normative whiteness were constructed together around (mis)representations of blackness and music. By policing the body in public space and covering music on the stage and later on the airwaves, this process simultaneously centered stereotypes of masculinity and denied the agency of masculine power to men. While he does not delve into the specific musical sleights of hand in blackface minstrelsy, his argument accurately stresses the ways that commercially available music was constructed largely without regard to African-American musical performance practice. …

Refactoring network infrastructure to improve manageability

Managing a home network is challenging because the underlying infrastructure is so complex. Existing interfaces either hide or expose the network's underlying complexity, but in both cases, the information that is shown does not necessarily allow a user to complete desired tasks. Recent advances in software defined networking, however, permit a redesign of the underlying network and protocols, potentially allowing designers to move complexity further from the user and, in some cases, eliminating it entirely. In this paper, we explore whether the choices of what to make visible to the user in the design of today's home network infrastructure, performance, and policies make sense. We also examine whether new capabilities for refactoring the network infrastructure - changing the underlying system without compromising existing functionality - should cause us to revisit some of these choices. Our work represents a case study of how co-designing an interface and its underlying infrastructure could ultimately improve interfaces for that infrastructure.

A framework for analysing supply chain performance evaluation models

Abstract Supply chain management creates value for companies, customers and stakeholders interacting throughout a supply chain. The strategic dimension of supply chains makes it paramount that their performances are measured. In today's performance evaluation processes, companies tend to refer to several models that will differ in terms of corporate organisation, the distribution of responsibilities and supply chain maturity. The present article analyzes various models used to assess supply chains by highlighting their specific characteristics and applicability in different contexts. It also offers an analytical grid breaking these models down into seven layers. This grid will help managers evolve towards a model that is more suitable for their needs.

MedRen 2010

July 2010 saw music students, scholars and performers from across the world descend on Royal Holloway, University of London, for the annual Medieval and Renaissance Music Conference. A total of 177 delegates attended over the four days, a record figure in the conference's history. The event was organized and impeccably run by Helen Deeming and a team of her students. The conference reflected some of the leading research currently taking place in medieval and Renaissance music. Ninety-eight papers, most in English but with a small number in other European languages, were given by speakers from 21 countries. Subjects ranged from studies of pre-Gregorian chant, through to the considerations of song and gender in the Middle Ages and the present-day marketing of polyphony. The latter paper, ‘The production and marketing of Renaissance polyphony in the modern age’ was given by freelance conductor and performer David Allinson, who discussed the place of sacred polyphony within today's secular performance and recording contexts. Allinson's enlightening and entertaining paper was followed by a response from Matthew O’Donovan, a member of Stile Antico, who was able to share his first-hand experience of the promotion of early music. Allinson's paper was one of nine given on the topic of Music in Tudor and Stuart England. Other papers within this topic included discussions of Byrd, Browne, Sheppard, music for Queen Elizabeth I's Accession, Edward Paston's music collection, and a newly discovered portrait of Nicholas Lanier. In addition there were a number of panels devoted to music in 16th-century Italy, covering topics such as secular music, publishing in Counter-Reformation Rome, Willaert and Weerbeke in Venice, and courtly patronage and public performance. Also well represented was Iberia, with papers ranging from reflections of 15th-century Iberian chapels in the Vatican Archives, to Royal exequies in early 16th-century Spain and an anonymous Requiem Mass. Pierre de la Rue was given particular prominence, with seven papers dedicated to his motets.

Incremental and Verified Modeling of the PCI Express Protocol

PCI Express is a modern, high-performance communication protocol implementing sophisticated features to meet today's performance demands. Although an off-chip protocol, PCI Express implements many principles of future on-chip communication architectures. It is a highly complex protocol that is hard to verify formally. We present the application of a new approach to the PCI Express transaction and data link layers. The methodology is based on a series of model transformation steps and revises the traditional modeling and verification workflow for designing on-chip protocols. Major parts of PCI Express, including performance-related optimizations and fault-tolerance features, are modeled incrementally to control the complexity and composed to a single model. The work has been accomplished in the Isabelle/HOL theorem prover. By restricting the models to an executable subset of the specification language, we have been able to combine the advantages of specifying in a theorem prover with the advantages of executable models in a functional programming language.

32.4: Quantum Dot Light Emitting Diodes for Full‐color Active‐matrix Displays

AbstractQuantum dot light emitting diodes (QLEDs) are a printable thin film electroluminescent technology that delivers exceptional color and efficiency at low cost of manufacture for display and solid‐ state lighting applications. We report on our progress developing efficient, stable QLEDs for full‐color active‐matrix displays, including recent advances in device performance, lifetime and Cadmium‐free QLEDs. Current QLED devices exhibit peak luminance efficiencies exceeding 50 cd/A, luminous power efficiencies greater than 20 lm/W and operational lifetimes exceeding 300 hours at 1,000 nits. Our most recent QLED efficiency results suggest that today's QLED performance is within a factor of two of the theoretical limit.

A GHz Spintronic-Based RF Oscillator

A nano-sized oscillator for RF applications is presented which is based on two spintronic effects, the tunneling magnetoresistance (TMR) and the spin momentum transfer torque. The oscillation frequency is several GHz and can be tuned by both a DC bias current and an external DC magnetic field. High compactness, high tunability and full compatibility with standard CMOS process make this spin torque nano-oscillator (STNO) a promising candidate for future RF transceivers. The main issues to be addressed are spectral purity and output power. First measurements on a hybrid built connecting the STNO to a dedicated wideband amplifier show that today's performance in terms of power is close to but not yet compatible with telecommunication standard requirements. Using time domain analysis we show that frequency fluctuations are an issue for spectral purity. Frequency synthesis concepts based on STNOs are also discussed.

A generic environment for modelling future launch operations—GEM-FLO: a success story in generic modelling

Several NASA programs have been established to study and improve the current launch capability to meet the need for more aggressive space exploration in the future. Numerous launch systems have been proposed by different government and commercial organizations with the potential goal of replacing the Space Shuttle. NASA must evaluate new designs and technologies with the objective of improving upon today's Shuttle cost, performance, and turnaround time, before the government or commercial organizations pursue the large undertaking of a new launch system. To address this issue, the Generic Simulation Environment for Modelling Future Launch Operations (GEM-FLO) was developed to accurately predict processing turnaround times and other effectiveness criteria and support making key business and program decisions. GEM-FLO utilizes a generic modelling paradigm to provide a single platform for modelling different designs, which helped significantly cut the cost of these studies. This paper documents a success story in generic simulation modelling.
