Like two ships

In this video, the words animated on screen are sometimes the same and sometimes different from those spoken by a male voice. Both narratives, written and spoken, are constructed entirely from clichés and mixed metaphors. This work examines processes of signification. It emphasizes disruption and disconnection as fundamental and generative operations in making meaning. Extending on post-structural and deconstructionist ideas, this work questions the relationship between written and spoken words. It upsets the assumed efficacy of metaphors and clichés to question the sites and mechanisms of signification.

Why the long face?

In this video, a male voice recites a script comprised entirely of jokes. Words flash on screen in time with the spoken words. Sometimes the two sets of words match, and sometimes they differ. This work examines processes of signification. It emphasizes disruption and disconnection as fundamental and generative operations in making meaning. Extending on post-structural and deconstructionist ideas, this work questions the relationship between written and spoken words. By deliberately confusing the signifying structures of jokes and narratives, it questions the sites and mechanisms of comprehension, humour and signification.

Then I let you

In this video, a male voice recites a teenage love poem. Words flash on screen in time with the spoken words. Sometimes the two sets of words match, and sometimes they differ. This work examines processes of signification. It emphasizes disruption and disconnection as fundamental and generative operations in making meaning. Extending on post-structural and deconstructionist ideas, this work questions the relationship between written and spoken words. By actively disrupting the sincerity of a teenage love poem, it questions the sites and mechanisms of comprehension, poetry and signification.

When There's Love

This work is an installation featuring three video projections, music and mirror balls. The three projections fill the walls with scrolling text borrowed from love song lyrics. Headphones in the gallery space allow you to hear a male voice sing the same words to an impromptu tune. Mirror balls send fragments of light spinning around the room while The Righteous Brothers’ Unchained Melody plays on repeat. This work emphasizes fragmentary, repetitious and spatio-temporal experiences of language in order to question the symbolic conventions of romance. By exaggerating and mixing hackneyed symbolic elements, this work extends on some of Nicolas Bourriaud’s theoretical insights into the creative and critical strategies of ‘postproduction’. In particular, it toys with the intersections between popular culture and inter-subjective experiences.

Bang

In this video, a male voice performs a script combining stories sourced from an anonymous confessions website. On screen, imagery of fireworks repeats into increasingly kaleidoscopic patterns. This work engages with the relationship between screen culture and contemporary subjectivity. It contrasts private confessions with the public spectacle of fireworks to question the ways screen cultures are informing constructions of subjectivity. By extending on some of Nicolas Bourriaud’s ideas around ‘postproduction’ and the creative and critical strategies of ‘editing’, it offers a speculative understanding of the contemporary tension between public and private.

Swell

In this video, an abstract kaleidoscopic pattern slowly morphs and changes colour. It is accompanied by a male voice performing a word association or stream-of-consciousness activity. This work examines the nature of consciousness and identity in a contemporary context. It mixes the languages of meditation, new age philosophy and pop-psychology. Drawing on Zygmunt Bauman’s theoretical work on “liquid modernity”, this work questions how and where we find space for contemplation in a contemporary context increasingly defined by temporary social bonds, consumer choices and private anxieties.

CIRQUE DE LA VOIX: VOCAL PERFORMANCES FOR THE 21st CENTURY AUDIENCE

This dissertation addresses the growing need to entice people to attend a classical solo vocal recital by incorporating thematic programming, multi-media presentations, collaborations and innovative marketing. It comprises four programs that use the above tactics, creating live performances of classical vocal music that appeal to the attention deficient 21st-century audience. Each program focuses on repertoire appropriate for the male alto voice and includes elements of spoken word, visual imagery and for movement through collaborations with actors, singers, dancers, designers and visual artists. Program one (March 1, 2004), La Voix Humaine: The Life of an Englishwoman in Music, Poetry, & Art, outlines the life of a fictitious Englishwoman through a self-composed narration, spoken by an actress, a Power Point presentation of visual art by 20th-century English artists and musical commentary provided by the collaboration of a vocalist and a pianist. Program two (October 15, 2004), La Voix Thfrmatique: Anima - Music that Moves, is a program of pieces ranging from the 14th- to the 20th-centuries of which half are choreographed by members of the University of Maryland Dance Department. Program three is a lecture recital entitled L 'Haute Voix: Identifying the High Male Voice and Appropriate Repertoire which is presented in collaboration with three singers, a pianist, a harpsichordist and a cellist. Program four, La Voix Dramatique: Opera Roles for the Countertenor Voice, comprises performances of George Frederic Handel's Giulio Cesare in Egitto (1724) in collaboration with the Maryland Opera Studio and the Clarice Smith Performing Arts Center (Leon Major, director; Kenneth Merrill, conductor). There are two performances each of the title role, Cesare (April 15 & 17, 2005), and his nemesis, Tolomeo (April 21 & 23,2005). All programs are documented in a digital audio format available on compact disc and are accompanied by program notes also available in digital format. Programs two and four are also documented in digital video format available on digital video disc.

Acústica de las iglesias jesuíticas como parte del patrimonio integral en Córdoba y San Ignacio Miní

En esta investigación se aborda el tema del comportamiento acústico de las Iglesias Jesuíticas de la ciudad de Córdoba (Argentina) y San Ignacio Mini ubicada en la localidad de San Ignacio, provincia de Misiones (Argentina), construidas hace dos siglos atrás y declaradas Patrimonio de la Humanidad, con el objetivo de evaluar los parámetros que determinan la comprensión de la palabra y la aptitud de cada una de las iglesias para el canto y la música religiosa. En una primera etapa la investigación se orientó a profundizar en las características constructivas interiores de cada templo y a proponer una metodología de análisis para comparar los resultados de las mediciones objetivas, realizadas mediante la implementación de mediciones in situ, con los resultados de las apreciaciones subjetivas resultantes de la elaboración de encuestas, a los fines de caracterizar acústicamente cada espacio sonoro. Se seleccionaron, para la caracterización objetiva de cada templo, aquellos parámetros que permiten sintetizar las propiedades acústicas relacionadas con la música y la palabra, y aquellos que posibilitan medir la proporción efectiva de las primeras reflexiones, consideradas como índices subjetivos de la capacidad de distinción del sonido por parte del oyente. Se comparan los valores alcanzados con las preferencias subjetivas obtenidas en las encuestas de opinión. Se relevaron tiempos de reverberación altos en todas iglesias, fuera de los considerados óptimos para cada recinto. Se analizaron los índices de calidad y se comprobó cómo influyen los diferentes materiales en el comportamiento acústico de cada recinto. Para la evaluación subjetiva se implementó una encuesta ya validada en la que se privilegió la fácil asociación entre parámetros acústicos y psicoacústicos, esto posibilitó encontrar aquellos parámetros objetivos, simulados con público, que estuviesen fuertemente relacionados con el juicio subjetivo, así como aquellos con menor correlación. La búsqueda y relevamiento de material grafico, fotográfico y otros documentos históricos posibilitó la reconstrucción de cada iglesia para su modelización y la evaluación del comportamiento de todos los templos con la presencia de feligreses, no habiéndose podido realizar mediciones bajo esta condición. El interés por obtener datos acústicos más precisos de la Iglesia San Ignacio Mini, que actualmente se encuentra en ruinas, llevó a utilizar herramientas más poderosas de cálculo como el método de las fuentes de imagen “Ray Tracing Impact” por medio del cual se logró la auralización. Para ello se trabajó con un archivo de audio que representó la voz masculina de un sacerdote en el idioma jesuítico-guaraní, recuperando así el patrimonio cultural intangible. ABSTRACT This research addresses the acoustic behavior of the Jesuit Churches in Cordoba City (Argentina) and San Ignacio Mini (located in the town of San Ignacio, Misiones, Argentina), built two centuries ago and declared World Heritage Sites, with the objective to evaluate the parameters that determine the speech comprehension and the ability of each of the churches for singing of religious music. The first step of the work was aimed to further investigate the internal structural characteristics of each temple and to propose an analysis methodology to compare the objective results of in situ measurements with the subjective results of surveys, in order to characterize acoustically each sound-space. For the subjective characterization of each temple, those parameters that allow synthesizing the acoustic properties related to music & speech and measuring the subjective indices for the recognition of sounds, were selected. Also, the values were compared with the ones obtained from the surveys. High reverberation times were found in all churches, which is not considered optimal for the enclosed areas of the temples. The quality indices were analyzed and it was found how the different materials influence in the acoustic behavior of each enclosure. For subjective evaluation, a survey was implemented (that was previously validated) where the association between acoustic and psychoacoustic parameters was privileged; this allowed to find those objective parameters who were strongly related to the subjective ones, as well as those with lower correlation. Photographic and graphic material and other historical documents allowed the reconstruction of each church for its modeling, and also the evaluation of the performance of all the temples in the presence of their congregation. The interest in obtaining more accurate acoustic data of the San Ignacio Mini Church, which is now in ruins, led to the use of most powerful methods, as for example the image-sources "Ray Tracing Impact" method. For this, an audio archive was used, representing a male voice of a priest in the Jesuit-Guaraní language; recovering in this way intangible cultural heritage.

"Things I did not know”: Retrospectives on a Canadian rural male youth suicide using an instrumental photo voice case study

In Canada, it is young rural based men who are at the greatest risk for suicide. While there is no consensus on the reasons for this, evidence points to contextual social factors including isolation, lack of confidential services and pressure to uphold restrictive norms of rural masculinity. In this article we share findings drawn from an instrumental photo voice case study to distil factors contributing to the suicide of a young Canadian rural based man. Integrating photo voice methods and in-depth qualitative we conducted interviews with 7 family members and close friends of the deceased. The interviews and image data were analyzed using constant comparative methods to discern themes related to participants’ reflections on and perceptions about rural male suicide. Three inductively derived themes, “Missing the signs”, “Living up to his public image” and “Down in Rural Canada ” reflect the challenges that survivors and young rural men can experience in attempting to be comply with restrictive dominant ideals of masculinity. We conclude that community based suicide prevention efforts would benefit from gender-sensitive and place specific approaches to advancing men’s mental health by making tangibly available and affirming an array of masculinities to foster the well-being of young rural based men.

An innovative approach to the assessment of nutrient intake in adults with type 2 diabetes : the development, trial and evaluation of a mobile phone photo/voice dietary record

Nutrition interventions in the form of both self-management education and individualised diet therapy are considered essential for the long-term management of type 2 diabetes mellitus (T2DM). The measurement of diet is essential to inform, support and evaluate nutrition interventions in the management of T2DM. Barriers inherent within health care settings and systems limit ongoing access to personnel and resources, while traditional prospective methods of assessing diet are burdensome for the individual and often result in changes in typical intake to facilitate recording. This thesis investigated the inclusion of information and communication technologies (ICT) to overcome limitations to current approaches in the nutritional management of T2DM, in particular the development, trial and evaluation of the Nutricam dietary assessment method (NuDAM) consisting of a mobile phone photo/voice application to assess nutrient intake in a free-living environment with older adults with T2DM. Study 1: Effectiveness of an automated telephone system in promoting change in dietary intake among adults with T2DM The effectiveness of an automated telephone system, Telephone-Linked Care (TLC) Diabetes, designed to deliver self-management education was evaluated in terms of promoting dietary change in adults with T2DM and sub-optimal glycaemic control. In this secondary data analysis independent of the larger randomised controlled trial, complete data was available for 95 adults (59 male; mean age(±SD)=56.8±8.1 years; mean(±SD)BMI=34.2±7.0kg/m2). The treatment effect showed a reduction in total fat of 1.4% and saturated fat of 0.9% energy intake, body weight of 0.7 kg and waist circumference of 2.0 cm. In addition, a significant increase in the nutrition self-efficacy score of 1.3 (p<0.05) was observed in the TLC group compared to the control group. The modest trends observed in this study indicate that the TLC Diabetes system does support the adoption of positive nutrition behaviours as a result of diabetes self-management education, however caution must be applied in the interpretation of results due to the inherent limitations of the dietary assessment method used. The decision to use a close-list FFQ with known bias may have influenced the accuracy of reporting dietary intake in this instance. This study provided an example of the methodological challenges experienced with measuring changes in absolute diet using a FFQ, and reaffirmed the need for novel prospective assessment methods capable of capturing natural variance in usual intakes. Study 2: The development and trial of NuDAM recording protocol The feasibility of the Nutricam mobile phone photo/voice dietary record was evaluated in 10 adults with T2DM (6 Male; age=64.7±3.8 years; BMI=33.9±7.0 kg/m2). Intake was recorded over a 3-day period using both Nutricam and a written estimated food record (EFR). Compared to the EFR, the Nutricam device was found to be acceptable among subjects, however, energy intake was under-recorded using Nutricam (-0.6±0.8 MJ/day; p<0.05). Beverages and snacks were the items most frequently not recorded using Nutricam; however forgotten meals contributed to the greatest difference in energy intake between records. In addition, the quality of dietary data recorded using Nutricam was unacceptable for just under one-third of entries. It was concluded that an additional mechanism was necessary to complement dietary information collected via Nutricam. Modifications to the method were made to allow for clarification of Nutricam entries and probing forgotten foods during a brief phone call to the subject the following morning. The revised recording protocol was evaluated in Study 4. Study 3: The development and trial of the NuDAM analysis protocol Part A explored the effect of the type of portion size estimation aid (PSEA) on the error associated with quantifying four portions of 15 single foods items contained in photographs. Seventeen dietetic students (1 male; age=24.7±9.1 years; BMI=21.1±1.9 kg/m2) estimated all food portions on two occasions: without aids and with aids (food models or reference food photographs). Overall, the use of a PSEA significantly reduced mean (±SD) group error between estimates compared to no aid (-2.5±11.5% vs. 19.0±28.8%; p<0.05). The type of PSEA (i.e. food models vs. reference food photograph) did not have a notable effect on the group estimation error (-6.7±14.9% vs. 1.4±5.9%, respectively; p=0.321). This exploratory study provided evidence that the use of aids in general, rather than the type, was more effective in reducing estimation error. Findings guided the development of the Dietary Estimation and Assessment Tool (DEAT) for use in the analysis of the Nutricam dietary record. Part B evaluated the effect of the DEAT on the error associated with the quantification of two 3-day Nutricam dietary records in a sample of 29 dietetic students (2 males; age=23.3±5.1 years; BMI=20.6±1.9 kg/m2). Subjects were randomised into two groups: Group A and Group B. For Record 1, the use of the DEAT (Group A) resulted in a smaller error compared to estimations made without the tool (Group B) (17.7±15.8%/day vs. 34.0±22.6%/day, p=0.331; respectively). In comparison, all subjects used the DEAT to estimate Record 2, with resultant error similar between Group A and B (21.2±19.2%/day vs. 25.8±13.6%/day; p=0.377 respectively). In general, the moderate estimation error associated with quantifying food items did not translate into clinically significant differences in the nutrient profile of the Nutricam dietary records, only amorphous foods were notably over-estimated in energy content without the use of the DEAT (57kJ/day vs. 274kJ/day; p<0.001). A large proportion (89.6%) of the group found the DEAT helpful when quantifying food items contained in the Nutricam dietary records. The use of the DEAT reduced quantification error, minimising any potential effect on the estimation of energy and macronutrient intake. Study 4: Evaluation of the NuDAM The accuracy and inter-rater reliability of the NuDAM to assess energy and macronutrient intake was evaluated in a sample of 10 adults (6 males; age=61.2±6.9 years; BMI=31.0±4.5 kg/m2). Intake recorded using both the NuDAM and a weighed food record (WFR) was coded by three dietitians and compared with an objective measure of total energy expenditure (TEE) obtained using the doubly labelled water technique. At the group level, energy intake (EI) was under-reported to a similar extent using both methods, with the ratio of EI:TEE was 0.76±0.20 for the NuDAM and 0.76±0.17 for the WFR. At the individual level, four subjects reported implausible levels of energy intake using the WFR method, compared to three using the NuDAM. Overall, moderate to high correlation coefficients (r=0.57-0.85) were found across energy and macronutrients except fat (r=0.24) between the two dietary measures. High agreement was observed between dietitians for estimates of energy and macronutrient derived for both the NuDAM (ICC=0.77-0.99; p<0.001) and WFR (ICC=0.82-0.99; p<0.001). All subjects preferred using the NuDAM over the WFR to record intake and were willing to use the novel method again over longer recording periods. This research program explored two novel approaches which utilised distinct technologies to aid in the nutritional management of adults with T2DM. In particular, this thesis makes a significant contribution to the evidence base surrounding the use of PhRs through the development, trial and evaluation of a novel mobile phone photo/voice dietary record. The NuDAM is an extremely promising advancement in the nutritional management of individuals with diabetes and other chronic conditions. Future applications lie in integrating the NuDAM with other technologies to facilitate practice across the remaining stages of the nutrition care process.

Students’ perceptions of their own victimization: A youth voice perspective

This article investigates the perceptions of 156 students who were victims of both traditional and cyberbullying (117 female, 45 male), ages 10 to 17 years, as to which form of bullying was more hurtful. Overall, students perceived traditional victimization to be more hurtful than cyber victimization. Reasons identified in the data to explain the different perceptions of victims were categorized and found to relate to: the bully, the bystanders, the bullying incidents, the emotional impact on the victim, and the victim’s ability to respond. The perceptions of these students challenge a number of suppositions presented in the literature that attempt to explain why cyberbullying is associated with more negative outcomes than traditional bullying. The implications for antibullying programs to address these issues are discussed.

On the development of an automatic voice pleasantness classification and intensity estimation system

In the last few years, the number of systems and devices that use voice based interaction has grown significantly. For a continued use of these systems, the interface must be reliable and pleasant in order to provide an optimal user experience. However there are currently very few studies that try to evaluate how pleasant is a voice from a perceptual point of view when the final application is a speech based interface. In this paper we present an objective definition for voice pleasantness based on the composition of a representative feature subset and a new automatic voice pleasantness classification and intensity estimation system. Our study is based on a database composed by European Portuguese female voices but the methodology can be extended to male voices or to other languages. In the objective performance evaluation the system achieved a 9.1% error rate for voice pleasantness classification and a 15.7% error rate for voice pleasantness intensity estimation.
