Sentencing indigenous and non-indigenous women in Western Australia's higher courts : A summary of the main findings of a narrative study

This paper presents the main findings of a narrative examination of higher court sentencing remarks to explore the relationship between Indigeneity and sentencing for female defendants in Western Australia. Using the theoretical framework of focal concerns, we found that key differences in the construction of blameworthiness and risk between the sentencing stories of Indigenous and non-Indigenous female offenders, through the identification of issues such as mental health, substance abuse, familial trauma and community ties. Further, in the sentencing narratives, Indigenous women were viewed differently in terms of social costs of imprisonment.

The struggle for protection of environmental refugees: who's responsibility? Discourses from the United Nations and Non-governmental organizations

This thesis identifies, examines and problematizes some of the discourses that have so far come to light on the issue of protection for environmental refugees. By analyzing the discourses produced by the United Nations Office of the High Commissioner for Refugees (UNHCR) and two non-governmental organizations - the Environmental Justice Foundation (EJF) and Equity and Justice Working Group Bangladesh (EquityBD), I examine the struggling discourses that have emerged about how protection for environmental refugees has been interpreted. To do this, I rely on Ernesto Laclau and Chantal Mouffe's theory and method of discourse analysis. The results show that responsibilization is the main point of struggle in the discussions on the protection of environmental refugees. As a floating signifier, it was utilized by the discourses produced by the UNCHR and the selected NGOs in contingent ways and with different political objectives. The UNHCR discourse responsibilized both the environmental refugees for their own protection and the individual states. The EJF and EquityBD, by contrast, allocated responsibility for the protection of environmental refugees to the international community. These contingent understandings of responsibilization necessitated different justifications. While the EJF discourse relied on humanitarianism for the assistance of environmental refugees, the EquityBD discourse constructed a rights based, more permanent solution. The humanitarian based discourse of the EJF was found to be inextricably linked with the neoliberal discourse produced by the UNHCR. Both these discourses encouraged environmental refugees to stay in their homelands, undermining the politics of protection. Another way in which protection was undermined was by UNHCR's discourse on securitization. In this context, climate change induced displacement became threat to developed countries, the global economy and transnational classes. The struggling discourses about who/what has been allocated responsibility for the protection of environmental refugees also meant that identities of the displaced be constructed in specific ways. While the UNHCR discourse constructed as voluntary migrants and predators, the EJF and EquityBD discourses portrayed them as victims. However, even though the EJF discourse constructed them as victims, their reliance on humanitarianism could also be interpreted as a way of giving the environmental refugee a predator like identity. These discourses on responsibilization and identity formation clashed with each other in the aim of achieving a hegemonic position in discussions and debates about the protection of environmental refugees.

A Habermasian model of stakeholder (non)engagement and corporate (ir)responsibility reporting

Inspired by Habermas’ works, we develop a prescriptive conceptual model of stakeholder engagement and corporate social responsibility (CSR) reporting against which empirical descriptions can be compared and contrasted. We compare the high profile case of Kraft's takeover of Cadbury with the conceptual model to illustrate the gap between an ideal speech situation and practice. The paper conducts a desk study of documents relating to the takeover and interviews with stakeholders from the local community to gauge their views of stakeholder engagement and CSR reporting by Cadbury/Kraft. The findings lead to policy recommendations for enhancing stakeholder accountability through improved steering mechanisms.

Global civil society and adult education for social change : a postcolonial perspective

Adult education plays an important role in global economic development and features prominently in debates about changing requirements of post-industrial knowledge societies. This dominant technical-instrumental understanding of adult education in public discourse masks the transformative function of certain types of adult education - that is, the possibilities of adult education to improve social justice issues such as workers’ rights, human rights, civic participation in governance and socially just development. Given the increasing social stratification between and within the North and South in the global era, the potential of adult education to effect social change has been rediscovered by organisations within global civil society, namely international non-governmental organisations (INGOs). The broad objective of this research was to carry out an in-depth qualitative case study of a human rights advocacy program provided by a Northern INGO predominantly operating within the global South. The study analyses how participants see this program in terms of its potential to contribute to progressive social change in their home communities across the Asia-Pacific region. The following questions guided the study: 1. To what extent does this adult education program challenge existing systems of domination and marginalisation? 2. How did completion of the program affect participants’ views of their abilities to facilitate social action within their communities? Data sources for this research were interviews with 19 participants and staff and questionnaires from 28 participants of the program from a variety of countries in the Asia-pacific region. The gap in the literature that this study addressed is that existing empirical research sidelines the analysis of the globalisation, adult education, and social change nexus from a perspective that takes the marginalised other seriously, tending instead to mirror the material subjugation of the South in discursive practices. Social change is highly context-specific and strategies to advance it depend on the way in which people understand their reality and are affected by adverse social conditions. The present study employed a postcolonial framework that provided a holistic approach to analysing adult education for social change inclusive of material, political, and social conditions and the interplay between these from the local to the global level. The program convincingly exemplified an example of adult education for counter-hegemonic resistance against the dominant neoliberal discourse. It achieved this by enabling participants, based on Freirian pedagogical principles, to locate the problem of social change and frame their strategies to address it within mutually constitutive local and global developments and the discourses that describe them. It provided the underpinning knowledge and skills for effective advocacy and created opportunities to build networks between various stakeholders. At minimum, most advocates accord their participation in the program a supporting role in enhancing their ability to examine causes for social injustices and ways to address these. Some advocates even regarded their program participation as fundamental in understanding these issues. Almost all participants reported an increased skill-set that enabled them to become more effective advocates.

A microscopic simulation model to estimate Bus Rapid Transit (BRT) station service capacity with mixed stopping and non-stopping bus operation

Bus Rapid Transit (BRT) station is the interface between passenger and service. The station is crucial to line operation as it is typically the only location where buses can pass each other. Congestion may occur here when buses maneuvering into and out of the platform lane interfere with bus flow, or when a queue of buses forms upstream of the platform lane blocking the passing lane. However, some systems include operation where express buses pass the critical station, resulting in a proportion of non stopping buses. It is important to understand the operation of the critical busway station under this type of operation, as it affects busway line capacity. This study uses micro simulation to treat the BRT station operation and to analyze the relationship between station Limit state bus capacity (B_ls), Total Bus Capacity (B_ttl). First, the simulation model is developed for Limit state scenario and then a mathematical model is defined, calibrated for a specified range of controlled scenarios of mean and coefficient of variation of dwell time. Thereafter, the proposed B_ls model is extended to consider non stopping buses and B_ttlmodel is defined. The proposed models provides better understanding to the BRT line capacity and is useful for transit authorities for designing better BRT operation.

Pre-crash and non-crash traffic flow trends analysis on motorways

Crashes that occur on motorways contribute to a significant proportion (40-50%) of non-recurrent motorway congestions. Hence, reducing the frequency of crashes assists in addressing congestion issues (Meyer, 2008). Crash likelihood estimation studies commonly focus on traffic conditions in a short time window around the time of a crash while longer-term pre-crash traffic flow trends are neglected. In this paper we will show, through data mining techniques that a relationship between pre-crash traffic flow patterns and crash occurrence on motorways exists. We will compare them with normal traffic trends and show this knowledge has the potential to improve the accuracy of existing models and opens the path for new development approaches. The data for the analysis was extracted from records collected between 2007 and 2009 on the Shibuya and Shinjuku lines of the Tokyo Metropolitan Expressway in Japan. The dataset includes a total of 824 rear-end and sideswipe crashes that have been matched with crashes corresponding to traffic flow data using an incident detection algorithm. Traffic trends (traffic speed time series) revealed that crashes can be clustered with regards to the dominant traffic patterns prior to the crash. Using the K-Means clustering method with Euclidean distance function allowed the crashes to be clustered. Then, normal situation data was extracted based on the time distribution of crashes and were clustered to compare with the “high risk” clusters. Five major trends have been found in the clustering results for both high risk and normal conditions. The study discovered traffic regimes had differences in the speed trends. Based on these findings, crash likelihood estimation models can be fine-tuned based on the monitored traffic conditions with a sliding window of 30 minutes to increase accuracy of the results and minimize false alarms.

Analyzing busway station potential capacity under mixed stopping and non-stopping operation

Busway stations are the interface between passengers and services. The station is crucial to line operation as it is typically the only location where buses can pass each other. Congestion may occur here when buses manoeuvring into and out of the platform lane interfere with bus flow, or when a queue of buses forms upstream of the platform lane blocking the passing lane. Further, some systems include operation where express buses do not observe the station, resulting in a proportion of non-stopping buses. It is important to understand the operation of the station under this type of operation and its effect on busway capacity. This study uses microscopic simulation to treat the busway station operation and to analyse the relationship between station potential capacity where all buses stop, and Mixed Potential Capacity where there is a mixture of stopping and non-stopping buses. First, the micro simulation technique is used to analyze the All Stopping Buses (ASB) scenario and then statistical model is tuned and calibrated for a specified range of controlled scenarios of dwell time characteristics Subsequently, a mathematical model is developed for Mixed Stopping Buses (MSB) Potential Capacity by introducing different proportions of express (or non-stopping) buses. The proposed models for a busway station bus capacity provide a better understanding of operation and are useful to transit agencies in busway planning, design and operation.

Modelling busway operation with mixed stopping and non-stopping buses

This thesis investigated the complexity of busway operation with stopping and non-stopping buses using field data and microscopic simulation modelling. The proposed approach made significant recommendations to transit authorities to achieve the most practicable system capacity for existing and new busways. The empirical equations developed in this research and newly introduced analysis methods will be ideal tools for transit planners to achieve optimal reliability of busways.

The role of regulatory frameworks and non-state actors in creating sustainable diets

This presentation discussed the growing recognition of sustainable diets at international governance levels and how this reflects the challenges and win-win opportunities of living within our ecological limits. I assert that sustainable diets provide an example of how living within our ecological limits would actually make us better off even apart from environmental benefits. After determining whether Australians’ generally have a sustainable diet, I outlined how Australian regulators are attempting to address sustainable diets. I argued that the personal responsibility approach coupled with the focus on preventing or reducing overweight and obesity levels are proving incapable of bringing about long-term sustainable diets that will contribute to the health and well-being of Australian people.

A comparison of road traffic crashes along mountainous and non-mountainous roads in Sabah, Malaysia

Constrained topography and complex road geometry along rural mountainous roads often represent a demanding driving situation. As a result, traffic crashes along mountainous roads are likely to have different characteristics to crashes on roads in flatter areas; however, there is little research on this topic. The objective of this study is to examine the characteristics of road traffic crashes on rural mountainous roads and to compare these with the characteristics of crashes on non-mountainous roads. This paper explores and compares general crash characteristics including crash type, crash severity, roadway geometric features and environmental factors, and road user/vehicle characteristics. Five years of road traffic crash data (2008-2012) for Sabah were obtained from the Malaysian Institute of Road Safety Research. During this period, a total of 25,439 crashes occurred along federal roads in Sabah, of which 4,875 crashes occurred in mountainous areas. Categorical data analysis techniques were used to examine the differences between mountainous and non-mountainous crashes. Results show that the odds ratio of ‘out-of-control’ crashes and the crash involvement due to speeding are respectively about 4.2 times and 2.8 times higher on mountainous than non-mountainous roads. Other factors and crash characteristics that increase the odds of crashes along mountainous roads compared with non-mountainous roads include horizontal curved sections compared with straight sections, single-vehicle crashes compared with multi-vehicle crashes and weekend crashes compared with weekday crashes. This paper identifies some of the basic characteristics of crashes along rural mountainous roads to aid future research on traffic safety along mountainous roads.
