Women's bodies, self perception and physical activity : a naturalistic study of women's participation in aerobics classes

The aim of this study was to describe the behaviour and perceptions of women in aerobic or exercise to music classes. In particular, the study examined the meaning women attach to this activity choice and the interaction of aerobics participation with cultural pressures and beliefs such as that of the ‘ideal female bodyshape’. A naturalistic method of study was chosen in order to gain a comprehensive view of the subjective experience of aerobics participation. Approximately fifty female health club members were observed over a three month period in order to identify and describe patterns of involvement, behaviour and perception and the factors affecting them. Six groups of women were identified. These were ‘Naturals’, ‘Compulsive’, ‘Functional Feminist’. Several factors were observed as potentially contributing to the patterns observed. These included attitude toward perceived cultural ideals and pressures of female expectation and shape, perceptions of aerobics and exercise, pre-occupation with slenderness and bodyshape, self-image and body image. The relationship between these factors was found to be dynamic and reciprocal, with participation possibly intensifying or alternately reducing bodyshape concern. Aerobics was seen to have a multifaceted yet very individual and important appeal to the women observed.

The effects of phonological and morphological training on speech perception scores and grammatical judgments in deaf and hard-of-hearing children

Seventeen primary school deaf and hard-of-hearing children were given two types of training for 9 weeks each. Phonological training involved practice of /s, z, t, d/ in word final position in monomorphemic words. Morphological training involved learning and practicing the rules for forming third-person singular, present tense, past tense, and plurals. The words used in the two training types were different (monomorphemic or polymorphemic) but both involved word final /s, z, t, d/. Grammatical judgments were tested before and after training using short sentences that were read aloud by the child (or by the presenter if the child was unable to read them). Perception was tested with 150 key words in sentences using the trained morphemes and phonemes in word final position. Grammatical judgments for sentences involving the trained morphemes improved significantly after each type of training. Both types of training needed to be completed before a significant improvement was found for speech perception scores. The results suggest that both phonological and morphological training are beneficial in improving speech perception and grammatical performance of deaf and hard-of-hearing children and that both types of training were required to obtain the maximum benefit.

Separating the contributions of hearing, lexical knowledge and speech production to speech perception scores in children with hearing impairments.

Open-set word and sentence speech-perception test scores are commonly used as a measure of hearing abilities in children and adults using cochlear implants and/or hearing aids. These tests are usually presented auditorily with a verbal response. In the case of children, scores are typically lower and more variable than for adults with hearing impairments using similar devices. It is difficult to interpret children's speech-perception scores without considering the effects of lexical knowledge and speech-production abilities on their responses. This study postulated a simple mathematical model to describe the effects of hearing, lexical knowledge, and speech production on the perception test scores for monosyllabic words by children with impaired hearing. Thirty-three primary-school children with impaired hearing, fitted with hearing aids and/or cochlear implants, were evaluated using speech-perception, reading-aloud, speech-production, and language measures. These various measures were incorporated in the mathematical model, which revealed that performance in an open-set word-perception test in the auditory-alone mode is strongly dependent on residual hearing levels, lexical knowledge, and speech-production abilities. Further applications of the model provided an estimate of the effect of each component on the overall speech-perception score for each child.

Stimulus determinants and receptor mechanisms involved in the tactual perception of woollen fabrics

The dimensions of touch sensations were investigated in a series of human psychophysical experiments using woollen fabrics as stimuli and words from the textile industry literature as verbal descriptors of touch sensations. Roughness was shown to be an important dimension and was found to be encoded by two out of the four receptors in the skin that respond to specific frequencies of mechanical vibration.

Risk perception, risk communication and message framing : breast cancer and family history

Examines the relationships between risk perception, risk communication, and health protective behaviour in relation to breast cancer and family history. Qualitative research was conducted to develop a printed community resource. Theoretical and practical implications for health behaviour theory and risk communication are identified.

The roles of object-image relative motion and static depth information in the perception of heading

Investigates visual information that enables human to effectively guide their movement through the environment. This problem is fundamental to the study of human behaviour, since survival is contingent upon the acquisition of resources that lie in different locations throughout the environment.

Location, perception and dissolution of form 1991-1993

The thesis covers a series of two and three-dimensional installations created in the investigation of both metaphorical and literal perceptions of form. The journey leads from the idea of painted-related dissolution of form in the early works, to the translation from three-dimensional to two-dimensional installations, and lastly, to experimentation with sound works where non-physical form is explored.

User-centered evaluation of a virtual environment training system : utility of user perception measures

This study assessed the utility of measures of Self-efficacy (SelfEfficacy) and Perceived VE efficacy (PVEefficacy) for quantifying how effective VEs are in procedural task training. SelfEfficacy and PVEefficacy have been identified as affective construct potentially underlying VE efficacy that is not evident from user task performance. The motivation for this study is to establish subjective measures of VE efficacy and investigate the relationship between PVEefficacy, SelfEfficacy and User task performance. Results demonstrated different levels of prior experience in manipulating 3D objects in gaming or computer environment (LOE3D) effects on task performance and user perception of VE efficacy. Regression analysis revealed LOE3D, SelfEfficacy,
PVEefficacy explain significant portions of the variance in VE efficacy. Results of the study provide further evidence that task performance may share relationships with PVEefficacy and SelfEfficacy, and that affective constructs, such as PVEefficacy, and SelfEfficacy may serve as alternative, subjective measures of task performance that account for VE efficacy.

Cross-cultural assumptions about perception and identity in western socio-legal frameworks

Socio-legal analysis has relied heavily on Mnookin and Kornhauser's "bargaining in the shadow of the law" and Galanter's "litigotiation" concepts. These concepts provide a framework for examining the relationship between formal legal rules and other normative sources in out-of-court activity. In this paper we explore the extent to which these frameworks' Western assumptions about individualism, conflict and the rule of law would require adaptation if they were to be used to examine such phenomena in Chinese culture or in Australian-Chinese negotiations. In particular, we focus on the "difference" between: i) China and Confucian culture; and ii) Western society in terms of the Confucian principles relating to hierarchy, harmony, collectivism and face. These principles have fundamental implications for Chinese perceptions of appropriate dispute resolution behaviour. Western researchers who omit consideration of these perceptions and neglect the defining characteristics of Chinese identity will emerge with flawed projects.

Spoken language and speech perception abilities in deaf children

Despite early diagnosis, early fitting of more advanced sensory aids, early intervention, and intensive educational management, many children with severe to profound hearing loss are delayed in their acquisition of spoken language compared with their peers with normal hearing. More...Some of the greatest challenges facing educators of deaf children include determining where to focus intervention in order to maximise benefit, and establishing the most effective strategies for the development of age-appropriate language. The experimental research in this book examined the relationship between hearing, speech production, and vocabulary knowledge, and investigated the contributions of these factors to the overall speech perception performance of deaf children. This research also investigated the areas in which intervention would be most beneficial, and examined the effects of different types of intervention on the development of spoken language and speech perception skills in deaf children. The evaluation, analysis and intervention methods reported in this book provide an experimentally validated program for improving speech perception, speech production and spoken language skills of deaf children.

Creating digital divas-scaffolding perception change through secondary school and university alliances

Over the last 20 years much has been done to encourage female students to choose computing courses and computing careers. Some instances of positive effects have been reported, yet the proportional disparity in gender in this discipline continues to grow. This paper reports on a program called 'Digital Divas'. Digital Divas aims to scaffold positive perceptions around computing in the early years of secondary school by involving female students in upbeat computing experiences over a semester. It introduces university undergraduates to the secondary classroom to provide informal role models and mentors, as well as interactions with young computing professionals. This classroom environment enables computer applications to be more strongly linked with future careers. The commitment to a semester length unit was influential in changing perceptions about girls and computing, and the program was supported by the wider school community. We posit that this type of curriculum intervention is needed and has the potential to build technical human capital in female students.

Effects of parental perception of neighbourhood deprivation and family environment characteristics on pro-social behaviours among 4-12 year old children

Objective : To assess the effect family environment stressors (e.g. poor family functioning and parental psychological distress) and neighbourhood environment on child prosocial behaviour (CPB) and child difficulty behaviour (CDB) among 4-to-12 year old children.

Methods : Analysis of the 2006 Victorian Child Health and Wellbeing Survey (VCHWS) dataset derived from a statewide cross-sectional telephone survey, with a final total sample of 3,370 children.

Results : Only family functioning, parental psychological distress, child gender, and age were associated with CPB, explaining a total of 8% of the variance. Children from healthily functioning families and of parents without any psychological distress exhibited greater prosocial behaviours than those from poorly functioning families and of parents with mental health problems. Neighbourhood environment was not found to contribute to CPB. A total of eight variables were found to predict CDB, explaining a total of 16% of the variance. Poor family and parental psychological functioning as well as poor access to public facilities in the neighbourhood were associated with conduct problems in children.

Conclusion : Our results point to the importance of the family environment in providing a context that fosters the development of empathic, caring and responsible children; and in buffering children in exhibiting behaviour difficulties during the formative years of life. Programs aimed at promoting prosocial behaviours in children need to target stressors on the family environment.
