From the medicalisation of dementia to the politics of memory and identity in three Spanish documentary films:Bicicleta, cullera, poma, Las voces de la memoria and Bucarest: la memòria perduda

This paper explores how the concept of Alzheimer’s disease (AD) is constructed through Spanish media and documentary films and how it is represented. The article analyses three documentary films and the cultural and social contexts in and from which they emerged: Solé´s Bucarest: la memòria perduda [Bucharest: Memory Lost] (2007), Bosch´s Bicicleta, cullera, poma [Bicycle, Spoon, Apple] (2010) , and Frabra’s Las voces de la memoria [Memory´s Voices] (2011). The three documentary films approach AD from different perspectives, creating well-structured discourses of what AD represents for contemporary Spanish society, from medicalisation of AD to issues of personhood and citizenship. These three films are studied from an interdisciplinary perspective, in an effort to strengthen the links between ageing and dementia studies and cultural studies. Examining documentary film representations of AD from these perspectives enables semiotic analyses beyond the aesthetic perspectives of film studies, and the exploration of the articulation of knowledge and power in discourses about AD in contemporary Spain

Build-up of auditory stream segregation induced by tone sequences of constant or alternating frequency and the resetting effects of single deviants

Three experiments investigated the dynamics of auditory stream segregation. Experiment 1 used a 2.0-s constant-frequency inducer (10 repetitions of a low-frequency pure tone) to promote segregation in a subsequent, 1.2-s test sequence of alternating low- and high-frequency tones. Replacing the final inducer tone with silence reduced reported test-sequence segregation substantially. This reduction did not occur when either the 4th or 7th inducer was replaced with silence. This suggests that a change at the induction/test-sequence boundary actively resets buildup, rather than less segregation occurring simply because fewer inducer tones were presented. Furthermore, Experiment 2 found that a constant-frequency inducer produced its maximum segregation-promoting effect after only 3 tone cycles - this contrasts with the more gradual build-up typically observed for alternating sequences. Experiment 3 required listeners to judge continuously the grouping of 20-s test sequences. Constant-frequency inducers were considerably more effective at promoting segregation than alternating ones; this difference persisted for ∼10 s. In addition, resetting arising from a single deviant (longer tone) was associated only with constant-frequency inducers. Overall, the results suggest that constant-frequency inducers promote segregation by capturing one subset of test-sequence tones into an on-going, pre-established stream and that a deviant tone may reduce segregation by disrupting this capture. © 2013 Acoustical Society of America.

QoE-aware power management in vehicle-to-grid networks:a matching-theoretic approach

Frequency, time and places of charging and discharging have critical impact on the Quality of Experience (QoE) of using Electric Vehicles (EVs). EV charging and discharging scheduling schemes should consider both the QoE of using EV and the load capacity of the power grid. In this paper, we design a traveling plan-aware scheduling scheme for EV charging in driving pattern and a cooperative EV charging and discharging scheme in parking pattern to improve the QoE of using EV and enhance the reliability of the power grid. For traveling planaware scheduling, the assignment of EVs to Charging Stations (CSs) is modeled as a many-to-one matching game and the Stable Matching Algorithm (SMA) is proposed. For cooperative EV charging and discharging in parking pattern, the electricity exchange between charging EVs and discharging EVs in the same parking lot is formulated as a many-to-many matching model with ties, and we develop the Pareto Optimal Matching Algorithm (POMA). Simulation results indicates that the SMA can significantly improve the average system utility for EV charging in driving pattern, and the POMA can increase the amount of electricity offloaded from the grid which is helpful to enhance the reliability of the power grid.
