Participatory sensing and education: helping the community mitigate sleep disturbance from traffic noise

Purpose – This paper aims to present a project in Australia, where participants use smartphones to measure the level of traffic noise in their homes. Through the data collected, participants learn if they are subjected to sleep disturbances and, if so, understand how they can manage the issue to protect their health. The project also has a secondary purpose: the local council would like to engage its community through the exercise and be seen as acting on the community’s problems.

2Loud? Monitoring traffic noise with mobile phones

The World Health Organization has recently focused attention on guidelines for night noise in urban areas, based on significant medical evidence of the adverse impacts of exposure to excessive traffic noise on health, especially caused by sleep disturbance. This includes serious illnesses, such as hypertension, arteriosclerosis and myocardial infarction. 2Loud? is a research project with the aim of developing and testing a mobile phone application to allow a community to monitor traffic noise in their environment, with focus on the night period and indoor measurement. Individuals, using mobile phones, provide data on characteristics of their dwellings and systematically record the level of noise inside their homes overnight. The records from multiple individuals are sent to a server, integrated into indicators and shared through mapping. The 2Loud? application is not designed to replace existing scientific measurements, but to add information which is currently not available. Noise measurements to assist the planning and management of traffic noise are normally carried out by designated technicians, using sophisticated equipment, and following specific guidelines for outdoors locations. This process provides very accurate records, however, for being a time consuming and expensive system, it results in a limited number of locations being surveyed and long time between updates. Moreover, scientific noise measurements do not survey inside dwellings. In this paper we present and discuss the participatory process proposed, and currently under implementation and test, to characterize the levels of exposure to traffic noise of residents living in the vicinity of highways in the City of Boroondara (Victoria, Australia) using the 2Loud? application.

Reflecting on participatory research in environmental education : some issues for methodology

We reflect on methodological issues arising in two of our own research projects as a form of practice, as a way of engaging in a praxis of project research. The projects chosen for this purpose are themselves concerned with teacher education and curriculum development in environmental education: they include participatory “reflective practice” processes in exploring issues relating to formal education in schools and informal education in communities and are grounded in the specific contexts of developing countries.
We discuss issues in participatory research such as:
• Whose research agenda gets to be explored?
• The importance of project partnerships
• Participants’ preconceptions about the nature of research
• What is “rigor” in participatory research in environmental education?
• The Colonialist Dilemma: Avoiding the “package or perish” mentality
• The Bigger Picture: Technocratic Rationality and Participatory Research.

Investigating the distribution of acacia longifolia ssp. sophorae in south-west Victoria using satellite remote sensing and GIS

Mapping and analysis of the distribution of environmental weeds is an important component of strategic weed management. Such information is particularly important in managing 'native invaders', where invasion characteristics must be clearly understood prior to any management action being taken. This paper reports on an investigation of the current distribution of the native invader Acacia longifolia ssp. sophorae (Labill.) Court (coast wattle) in south-west Victoria, using remote sensing and Geographic Information Systems (GIS). Coast wattle was successfully mapped from Landsat ETM imagery using a supervised classification procedure, with 82%, of coast wattle shown on the map accurately depicting coast wattle on the ground. An estimated 11,448 ha were classified as supporting coast wattle, representing 12% of native vegetation in the study area. A more detailed GIS analysis in the Lower Glenelg National Park revealed coast wattle has invaded a limited number of vegetation types, and is more prevalent close to roads and within management zones associated with disturbance. The current regional extent of the species means widespread control is unlikely; hence the immediate focus should be on preventing further spread into areas where it is currently absent. Landsat imagery also proved to be a successful tool for mapping large scale coast wattle distribution, and could be used in long-term monitoring of the species.

Participatory research in EE: some issues of epistemology and methodology

The conference theme of epistemology and methodology suggests an interest in epistemological issues in environmental education research. I have argued previously that for too long there seemed to be a blindness in environmental education research: that there was an unwarranted assumption that all research in environmental education was and should be conducted within an applied science conceptual framework that did not recognise nor problematise the epistemological assumptions of research. In this paper I intend to address the issue of epistemological coherence between the substantive subject matters of environmental education on the one hand and research, methodology on the other. The paper will draw upon two recent international environmental education projects to explore issues concerning the nature, status and role of research in environmental education. A number of features of community-based environment development projects in two different settings will be described, illustrating the complexity and contextuality of environmental issues as subject matters for environmental education. The implications for research that seeks to acknowledge and respect relationships within community contexts will be considered in relation to the following questions: Whose research agenda? The importance of project partnerships Participants' preconceptions about the nature of research. What is 'rigor' in participatory research in environmental education'?

Getting it right: participatory information research with people with disabilities

Over the past two decades there has been a growing understanding of consumer requirements and advances in the design and development of accessible technology. However, research over the past decade confirms that significant barriers still exist for people with disabilities. These individuals constitute a diverse group of consumers who experience physical, cognitive, literacy, financial and attitudinal barriers to the use of technology or information. They regard themselves as experts on their access issues yet have been provided with few opportunities to participate in technology research that seeks to explore issues and provide consumer-focused solutions.

In this paper, the benefits of collaborative research and the use of participatory methods in a funded research project on accessible telecommunications information are described. The target consumer group for the project was people with significant communication difficulties, a group who are particularly disadvantaged due to speech, literacy and physical access issues with technology and information. The strategies used to facilitate participation are discussed and criteria from Zarb (1992) and Barnes (2003) are used to evaluate the participatory aspect of the project.

Development of low cost motion-sensing system

Micro-electro-mechanical system (MEMS) technology offers sensors with lower cost, smaller size, lower power consumption. In this paper, a kind of low cost motion-sensing system based MEMS sensors is developed. The objective of the design is low cost, small volume and light weight in order to be used in many fields. The constituting principle of the system is described. Algorithms and hardware of the system are researched. And the definition of coordinate, calculation of pose angle, transform of acceleration and calculation of the velocities and displacement of the moving object are presented with corresponding mathematics model and algorithms. The experiments are carried out in principle and results are given. It is proved that the low cost motion-sensing system is effective and correct.

Anion recognition and sensing in organic and aqueous media using luminescent and colorimetric sensors

This review article focuses primarily on the work carried in our laboratories over the last few years using luminescent and colorimetric sensors, where the anion recognition occurs through hydrogen bonding in organic or aqueous solvents. This review begins with the story of the discovery of fluorescent photoinduced electron transfer (PET) sensors for anions using charged neutral urea or thiourea receptors where both fluorescent and NMR spectroscopic methods monitored anion recognition. This work led to the development of dual luminescent and colorimetric anion sensors based on the use of the ICT based naphthalimide chromophore, where ions such as fluoride gave rise to changes in both the fluorescence and the absorption spectra of the sensors, but at different concentrations. Here, the former changes were due to hydrogen bonding interactions, whereas the latter was due to the deprotonation of acidic protons, giving rise to the formation of the bifluoride anion (HF2−). Modification of the 4-amino-l,8-naphthalimide moiety has facilitated the formation of colorimetric anion sensors that work both in organic or aqueous solutions. Such charge neutral receptor motifs have also been incorporated into organic scaffolds with norbomyl and calixarene backbones, which have enabled us to produce anion directed self-assembled structures.

Reconstructing child welfare through participatory and child centred professional practice

This questionnaire study examined the adjustment of 245 lone-parenting women following marital separation. A composite model included intrapsychic variables as intervening between demographic and contextual variables and adjustment (life satisfaction). Regression analyses showed that the demographic and contextual variables were partially mediated by the intrapsychic variables. The path model indicated that the intrapsychic variables (sense of coherence, control, depression, and grief) had a direct impact on life satisfaction and that there was an indirect path for depression through sense of coherence (SOC) and control. It was concluded that the intrapsychic variables had a more powerful relationship with women's post-separation life satisfaction than did the demographic/contextual variables. Social implications and recommendations for future policy are considered.

Are the potential benefits of a community-based participatory approach to public health research worth the potential cost?

Much of public health research is conducted in a community setting or is designed to target particular population groups. Community-based participatory research (CBPR) is gaining recognition as good practice in studies of this type(Flicker et al 2007). Its merit is based on the inclusion of the community as active participants at all stages of the research process (Goodman 2006). The focus on justice and equity in this approach is seen to contribute to a range of additional potential research benefits including increased relevance and sustainability of interventions arising from the research ( Blumenthal 2004; Wallestein 2006) However, it is widely acknowledged that adoption of a consciously CBPR approach requires additional expertise. time and resources from researchers and from communities (Tanjasiri et al 2002; Massaro & Claiborne 2001; Israel et al 1998). Adoption of CBPR is also limited by existing infrastructures which are supportive of more· traditional models of research. Changes to professional development programs, funding guidelines and criteria. grant review processes and ethics requirements are needed to support increased application of this approach (Israel et al 2001). As all research resources are limited, the potential additional benefits offered by CBPR over and above a more traditional research approach need to be weighed against the potential additional costs involved. Changes to research infrastructure are unlikely to occur until the costs and
benefits of a consciously CBPR approach as compared to a more traditional research approach can be demonstrated.

This is an exploratory paper that summarises the arguments put forward to date in relation to CBPR. A research case study and an evaluation framework are then used for a conceptual analysis of differences in the potential costs and benefits of the two approaches. Firstly, the paper describes the differences between traditional and consciously CBPR approaches. The reported benefits of CBPR are then outlined, followed by a discussion of the potential costs. Finally, the potential costs are compared to the potential benefits of using a CBPR approach, using a case study of existing research.

Reconstructing child welfare through participatory and child-centred professional practice : a conceptual approach

The 'child' in child welfare/protection is seen as a dependent waif and an object of interest, on whose behalf adults speak and act. An alternative perspective has argued for child-centredness, and includes concepts of child liberation, rights and citizenship. Policymakers and practitioners who may accept the underlying principles may be concerned about the appropriateness and applicability of such principles in relation to practice with children and their parents in child welfare/protection cases. This paper discusses a conceptual framework for research that aims to explore participatory and child-centred professional practice by critically evaluating and developing, for professional practice, the practical meanings of 'participatory' and 'children as citizens'. We do not present research outcomes based on empirical data; instead, we present our conceptual framework as the first stage of research in progress into participatory and child-centred professional practice.
