The Multidimensionality of Presbycusis: Hearing Losses on the Content and Relational Dimensions of Speech

Presbycusis, the age associated decline in hearing and listening, has been traditionally conceptualized as the progressive inability to distinguish phonemes and hence to apprehend the content of spoken communication. Based on the distinction between the content and relational dimensions of communication, this study posed the possibility that presbycusis also involves a loss of listening ability along the relational dimension of communication. Using five measures of speech discrimination and listening, the study confirmed that aging is significantly associated with losses on the content and relational dimensions of listening. Furthermore, there are different rates of aging for these two dimensions. Whereas the loss on the content dimension is linearly related to age, the loss on the relational dimension is curvilinearly related to age with little decline in ability until a relatively drastic loss occurs in the early to mid-70s. These results indicate that the communicative impact of presbycusis is considerably greater for the old elderly than for the young elderly. Thus, this study constitutes initial evidence for a multidimensional conception of presbycusis.     

Maori and the New Zealand values survey: The importance of research relationships

Abstract

Requirements for non‐Maori researchers to consult with Maori compete with “by Maori for Maori” research agendas. Nevertheless, Maori provide varying forms of consultation, with Maori perspectives rarely being entered into the literature. Following an invitation from the Centre for Social Health Outcomes Research and Evaluation (SHORE), members of the Whariki Research Group agreed to take a consultative role, providing Maori input into the New Zealand Values Survey 2004. After initial examination of the survey instrument and follow‐up on previous consultation with Maori, Whariki's main role focused on questions relevant to the Treaty of Waitangi (signed in 1840 between the United Kingdom and Maori) and to Maori. The questions and related findings were of particular salience in the context of ongoing controversy and challenges to the status of the Treaty in New Zealand and to the position of Maori. Here we describe research processes and relationships and present the findings with reference to their social and political implications.     

Looking After Children: assessing outcomes in child care. The experience of implementation

A Department of Health initiative has supported the implementation of Looking After Children in over 90 per cent of local authorities in England. The process has required major organisational change and new values and attitudes towards children looked after away from home. Difficulties arise where management and monitoring systems are not available to support these wider changes and to assess the quality of practice. Nevertheless clear benefits to using the system can be identified. Pilot projects in Sweden, Canada and Australia provide an opportunity to compare experiences internationally; strong parallels are evident in some of the current issues facing child welfare.     

Fishing in a Polluted Estuary: Fishing Behavior, Fish Consumption, and Potential Risk

People make subjective judgments about hazards relying on what they know and feel. These risk perceptions may be based on accurate or inaccurate information and are often optimistically biased. The existence of uncertainties in the evaluation of many environmental hazards effects how risks are perceived. This paper examines fish consumption and risk perception of urban fishermen in the New York/New Jersey estuary, in areas where there were consumption advisories. We interviewed 318 fishermen and crabbers in the Arthur Kill, Raritan Bay, and New Jersey shore. Fish were eaten an average of at least four times per month in all regions, but fishermen in the Arthur Kill fished most frequently, averaging over eight times per month. Although 60% of fishermen and crabbers in the Arthur Kill reported hearing warnings about consuming fish caught in these waters, 70% of fishermen and 76% of crabbers said they ate their catch. Significantly fewer fishermen in the Bay and Shore regions had heard warnings (28% and 30%, respectively), and more reported consuming their catch (88% and 82%, respectively). In all regions, most people thought that the fish were safe to eat, many believing they were "fresher" than store bought fish. Thus, most people ignored the consumption advisories in effect for these waters. Some of these people are consuming high quantities of fish and crabs, and thus are exposed to potentially deleterious levels of contaminants. In general, people failed to consider the possibility of chronic effects and did not perceive that this enjoyable, familiar pastime could be hazardous. Further, fishermen generally had great confidence in their own knowledge, which proved to be inaccurate in many cases, and often expressed distrust in the information source (government). Clearly, simply issuing consumption advisories is insufficient to promote risk-reducing behavior.     

Now Being Social: The Barrier of Designing Outdoor Play Spaces for Disabled Children

The design of outdoor public play spaces such that disabled children can make use of them is set in the three constructs of play, childhood and disability, drawing upon academic learning, international policy and national policy in England. The suggestion is made that one of the main barriers to the adequate provision of such spaces is that providers and designers do not know how to design such spaces. The paper explores the knowledge which is available to overcome this barrier and which might lead to the provision and design of appropriate outdoor play spaces that disabled children can more fully use.
