Smart meter devices and the effect of feedback on residential electricity consumption: Evidence from a natural experiment in Northern Ireland

Using a unique set of data and exploiting a large-scale natural experiment, we estimate the effect of real-time usage information on residential electricity consumption in Northern Ireland. Starting in April 2002, the utility replaced prepayment meters with advanced meters that allow the consumer to track usage in real-time. We rely on this event, account for the endogeneity of price and payment plan with consumption through a plan selection correction term, and find that the provision of information is associated with a decline in electricity consumption of 11-17%. We find that the reduction is robust to different specifications, selection-bias correction methods and subsamples of the original data. The advanced metering program delivers reasonably cost-effective reductions in carbon dioxide emissions, even under the most conservative usage reduction scenarios.

The principles and practice of interpreting cardiac rhythm strips: a seven-step model

This open learning zone article examines the cardiac cycle and the interpretation of cardiac rhythm strips. The article begins with a brief revision of related physiology followed by a description of normal sinus rhythm and the main cardiac rhythm abnormalities. The article concludes by providing easy to follow steps for use in the interpretation of cardiac rhythm strips with practice examples presented in the CPD task section.

(Dis‑)Harmony in movement: effects of musical dissonance on movement timing and form

While the origins of consonance and dissonance in terms of acoustics, psychoacoustics and physiology have been debated for centuries, their plausible effects on movement synchronization have largely been ignored. The present study aims to address this by investigating whether, and if so how, consonant/dissonant pitch intervals affect the spatiotemporal properties of regular reciprocal aiming movements. We compared movements synchronized either to consonant or to dissonant sounds, and showed that they were differently influenced by the degree of consonance of the sound presented. Interestingly, the difference was present after the sound stimulus was removed. In this case, the performance measured after consonant sound exposure was found to be more stable and accurate, with a higher percentage of information/movement coupling (tau-coupling) and a higher degree of movement circularity when compared to performance measured after the exposure to dissonant sounds. We infer that the neural resonance representing consonant tones leads to finer perception/action coupling which in turn may help explain the prevailing preference for these types of tones.

Gesture interaction in music for instruments and electroacoustic sounds

Esta tese apresenta alguns aspectos em como o fenómeno do gesto musical pode ser compreendido na percepção da interação musical na música para instrumentos e sons electroacústicos. Através de exemplos de análise, classificação e categorização de diferentes relacões gestuais entre instrumentos e sons electroacústicos, pretende-se estabelecer modelos específicos de interacção que podem ser aplicados como método analítico assim como na composição musical. A pesquisa parte de uma variedade de definições sobre gesto musical na música em geral, na música contemporânea e na música electroacústica em particular, para subsequentemente incluir as relações entre dois eventos sonoros com características diferentes - o electroacústico e o instrumental. São essencialmente abordadas as relações entre gestos musicais através da análise de diversas características: altura, ritmo, timbre, dinâmica, características contrapontísticas, espectromorfológicas, semânticas e espaciais. O resultado da pesquisa teórica serviu de suporte à composição de diversas obras, onde estes aspectos são explorados sob o ponto de vista da criação musical.

Sociology and Music Education. 'Sociología y Educación Musical'.

La comunidad académica y profesional de la educación musical analiza los problemas a los que se enfrentan en la educación desde un punto de vista sociológico. En primer lugar, se introduce al concepto de sociología y educación musical. Seguidamente, se exponen teorías con ejemplos prácticos de innovaciones pedagógicas aplicadas a la sociología en el marco de la educación musical en Europa y especialmente en Reino Unido.

Effect of priming cooperation or individualism on a collective and interdependent task: changeover speed in the 4 x 100-meter relay race

Priming effects of cooperation vs. individualism were investigated on changeover speed within a 4 x 100-m relay race. Ten teams of four adult beginner athletes ran two relays, a pretest race and an experimental race 3 weeks later. Just before the experimental race, athletes were primed with either cooperation or individualism through a scrambled-sentence task. Comparing to the pretest performance, cooperation priming improved baton speed in the exchange zone (+30 cm/s). Individualism priming did not impair changeover performance. The boundary conditions of priming effects applied to collective and interdependent tasks are discussed within the implicit coordination framework.
