Résumé :

The article introduces the topic of Latvian documentary theatre of the second decade of the twenty-first century using Michael Foucault’s concept of counter-memory. The article analyses a series of performances by artists of the Latvian post-Soviet and post-memory generation dealing with history and memory discourses and highlights the main strategies of use of countermemory discourses in the creation of national, cultural, and individual identities; emphasizing memory as a construct and highlighting strategies of its creation and maintenance; emphasizing the oppressive nature of dominant-disc

Résumé :

Step counting represents a valuable approach to monitor the amount of daily physical activity. The feet, wrist and trunk have been demonstrated as the ideal locations to automatically detect the number of steps through body-worn devices (i.e., step counters). Key features of such devices are high usability, practicality and unobtrusiveness. Therefore, the opportunity to integrate step-counting functions in daily worn accessories represents one of the recent and most important challenges. In this context, the present study aimed to investigate the validity of a smart-glasses-based step-counter

Résumé :

Low-level radiocarbon measurements were made using two liquid scintillation (LS) counters, both with passive lead shields of approximately the same dimensions. The first one had a conventional background reduction with low-activity lead and “high-low” coincidence bias selection, and the second one had a spectrum analysis background reduction based on the different three-dimensional pulse-height signal of background and beta pulses. The performance of commercial teflon-copper and glass vials were compared with both LS counters. Optimum counting conditions for the two detectors studied were also

The aerodynamic performance of a counter-rotating ducted fan in hover mode is numerically analyzed for different rotor spacings and duct diffusion angles. The design of the counter-rotating fan is inspired by a custom-designed single rotor ducted fan used in a previous study. The numerical model to predict the aerodynamic performance of the counter-rotating ducted fan is developed by adopting the frozen rotor approach for steady-state incompressible flow conditions. The relative angle between the front and the rear rotor is examined due to the usage of the frozen rotor model. The results show

Abstract. Eight rainfall events recorded from May to September 2013 at Hong Kong International Airport (HKIA) have been selected to investigate the performance of post-processing algorithms used to calculate the rainfall intensity (RI) from tipping-bucket rain gauges (TBRGs). We assumed a drop-counter catching-type gauge as a working reference and compared rainfall intensity measurements with two calibrated TBRGs operated at a time resolution of 1 min. The two TBRGs differ in their internal mechanics, one being a traditional single-layer dual-bucket assembly, while the other has two layers of

Résumé :

Purpose This paper aims to examine tensions around play, performance and artmaking as becoming in the mix of expected and taken-for-granted discourses implicit in an after-school ceramics makerspace (Perry and Medina, 2011). The authors look closely at one adolescent girl’s embodied performance to see how it ruptures the scripts for compliant bodies in the after-school program. While these performances take place out-of-school and in an arts studio, the tensions and explorations also resonate with broader issues around student embodied, performative and becomings that run counter to normalized

Résumé :

The present study examined the relationship between self-generated emotions and physical performance. All participants took part in five emotion induction conditions (happiness, anger, anxiety, sadness, and an emotion-neutral state) and we investigated their influence on the force of the finger musculature (Experiment 1), the jump height of a counter-movement jump (Experiment 2), and the velocity of a thrown ball (Experiment 3). All experiments showed that participants could produce significantly better physical performances when recalling anger or happiness emotions in contrast to the emotion

Résumé :

In this article, we explore the ongoing negotiations and tensions involved in creating high-performance play and livestreaming practices, produced through assemblages of creative networked actions between individuals, institutions, infrastructures and communities. From speedrunning communities to esports leagues, expert game cultures offer key cases to explore the conventions of expert gameplay, the politics of digital play itself and the formation of networked careers. These include performances (on/off screen, by players and spectators), ownership/governance (of the game, of third-party orga

Résumé :

Turbomachinery with double counter-rotating impellers offers more degrees of freedom in the choice of design and control parameters compared to conventional machines. For these innovative machines, the literature review shows that more publications concerning axial type turbomachines are available than centrifugal ones. This work deals with a design and experimental performance analysis, applied to two counter-rotating impellers of a centrifugal compressor “CRCC”. CRCC was designed with a specifically developed tool based on mean-line approach coupled with optimization algorithms and a stream-

AbstractThis special issue builds on empirical research to provide new insights into the interrelations between collective memory and legacies of political violence in the Balkans. The contributions pay particular attention to two major issues: First, they explore the ways in which individuals and groups respond to and cope with violent pasts by investigating commemorative practices including public performances, narratives, and negotiations of counter-memories. Second, they make explicit how people select and reassemble collective memories through remembering violent pasts to create and disse

Résumé :

This article argues for the consideration of the lecture-performance as a genre that offers rich possibilities for critical fashion discourse, one that is uniquely suited to the material, embodied nature of clothing.The article recounts a lecture-performance by Australian-based design group The Stitchery Collective, which explored moments in history that demonstrate fashion’s capacity to resist, rebel and turn the political into the fabulous. From Amelia Bloomer’s bloomers to the sans-culottes of revolutionary France, fashion has acted as a tool and medium for great social protest and momentum

Résumé :

Although antecedents of choking under pressure have been studied, prevention efforts have been somewhat inconsistent. Current choking-susceptibility criteria include trait anxiety (TA), self-consciousness (SC), and coping style. In the present case study, a college track-and-field athlete was self-identified as choking susceptible (CS), and a sport-specific mindfulness intervention to reduce levels of TA, SC, and alter coping to reduce choking susceptibility was implemented. The athlete identified as CS completed the 6-wk Mindful Sport Performance Enhancement (MSPE) program. Trait and state mi

Résumé :

In early modern Italy, an unusual form of exchange between Jewish and Christian communities materialized in Mantua: Jews in Mantua were required to perform an annual play as a tribute to their Gonzaga rulers. Elsewhere in the Italian peninsula, far more onerous “performances” were extorted from the Jews during carnival, but in the Mantuan performances, several communities—the ruling Gonzaga family, the Jewish community, and Christian audience members—interacted. I consider these performances a form of taxation because the full cost, which was extensive, was borne by the Jewish community. Howev

Résumé :

In this paper we show that poor student performance in a rural school is influenced by the classifications used for student learning and behaviour. We propose that the institution's organisation is conveyed via a classification schema that permeates and informs judgments about student progress and holds sway over teacher cognition. Category boundaries are set and differentiate between compliant and non-compliant students in the school in question. Conformity to expectations by compliant students can be mistaken for academic security. Rectifying disruptive and off-task behaviours can replace te

Résumé :

Hawai'i's most renowned song, "Aloha 'Oe," was composed by Queen Lili'uokalani before she was deposed by missionary settlers. Circulating in the cultural imaginary since the late nineteenth century, "Aloha 'Oe" was transformed from a love song into a dirge that erased the sovereign rights of Lili'uokalani in and beyond Hawai'i. This article theorizes "settler colonial nostalgia" as a gendered material and symbolic process of effecting indigenous displacement and expropriation. Providing an alibi for settler society and its beneficiaries, performances of the song center settler subjects as nost
