Post occupancy evaluation of a building employing windcatchers for summer ventilation

A combined windcatcher and light pipe (SunCatcher) was installed in the seminar room at the University of Reading, UK. Monitoring of indoor environment in real weather conditions was conducted to evaluate the application of windcatchers for natural ventilation. In addition, a subjective occupancy survey was undertaken. External weather conditions and internal indoor air quality indicators were recorded. The “tracer-gas decay” method using SF6 was used to establish air change rate for various conditions. The results indicated that the ventilation rate achieved through the windcatcher depends on the difference between internal and external air temperatures, and on wind speed and direction, in agreement with other published work in the area. The indoor air quality parameters were found to be within acceptable levels when the windcatcher was in operation. The measured air change rate was between 1.5ac/h and 6.8ac/h. Occupants’ questionnaires showed 75 per cent satisfaction with the internal conditions and welcomed the installation of the systems in UK buildings.

Life histories of music service histories, the past in inductees' present

This article discusses inductee music service teachers (to 25 years of age). It explores how their lives, as perceived, shape current identities in teaching and result in several career problems. Respondents were drawn from a comprehensive life history study of 28 Local Education Authority employees. Of this larger cohort, four were age 25 years and below, and the remaining 24 teachers made retrospective comments. Data were collected and analysed between October 2002 and March 2004. Principal findings suggest that schooling failed to address these educators' needs as musical learners; key childhood experiences were external of schools. This often resulted in an idealistic trajectory, in teenage years, towards an occupation as a performer. An occupation in music education was entirely disregarded. Consequently, inductees now consider training experiences an inappropriate platform for their professional lives. Managing group teaching and children's behaviour engenders considerable anxiety. Music service work is also deemed a transient state of affairs. There are implications for training, retention and professional development.

Primary music education: the misrepresentation of the ideals of curricula in research

The author starts from a historical viewpoint to suggest that, at primary level, we have tended to perpetuate a nineteenth-century notion of music education. This is evident in the selection and organisation of musical content in curriculum documents, the scope of the teacher-pupil transaction implicit in these and the assumptions about music education which underpin research on practice conducted at official policy level. In light of the introduction of the 1999 Revised Primary School Curriculum, with its change in emphasis, she notes that it is timely to reconsider the situation. Central to this is the need to challenge the notion of music as a set of delineated skills, to explore the relationship between the primary teacher and music, and to move towards a notion of research which acknowledges the richness of multiple interpretations teachers bring to the curriculum.

One’s own soundtrack: affective music synthesis

Computer music usually sounds mechanical; hence, if musicality and music expression of virtual actors could be enhanced according to the user’s mood, the quality of experience would be amplified. We present a solution that is based on improvisation using cognitive models, case based reasoning (CBR) and fuzzy values acting on close-to-affect-target musical notes as retrieved from CBR per context. It modifies music pieces according to the interpretation of the user’s emotive state as computed by the emotive input acquisition componential of the CALLAS framework. The CALLAS framework incorporates the Pleasure-Arousal-Dominance (PAD) model that reflects emotive state of the user and represents the criteria for the music affectivisation process. Using combinations of positive and negative states for affective dynamics, the octants of temperament space as specified by this model are stored as base reference emotive states in the case repository, each case including a configurable mapping of affectivisation parameters. Suitable previous cases are selected and retrieved by the CBR subsystem to compute solutions for new cases, affect values from which control the music synthesis process allowing for a level of interactivity that makes way for an interesting environment to experiment and learn about expression in music.

Use of auditory cues for wayfinding assistance in virtual environment: music aids route decision

This paper addresses the crucial problem of wayfinding assistance in the Virtual Environments (VEs). A number of navigation aids such as maps, agents, trails and acoustic landmarks are available to support the user for navigation in VEs, however it is evident that most of the aids are visually dominated. This work-in-progress describes a sound based approach that intends to assist the task of 'route decision' during navigation in a VE using music. Furthermore, with use of musical sounds it aims to reduce the cognitive load associated with other visually as well as physically dominated tasks. To achieve these goals, the approach exploits the benefits provided by music to ease and enhance the task of wayfinding, whilst making the user experience in the VE smooth and enjoyable.
