The use of public transport in coastal Australia : modes of travel to work and greenhouse emissions

Commuting to work is one of the most important and regular routines of transportation in towns and cities. From a geographic perspective, the length of people’s commute is influenced, to some degree, by the spatial separation of their home and workplace and the transport infrastructure. The rise of car ownership in Australia from the 1950s to the present was accompanied by a considerable decrease of public transport use. Currently there is an average of 1.4 persons per car in Australia, and private cars are involved in approximately 90% of the trips, and public transportation in only 10%. Increased personal mobility has fuelled the trend of decentralised housing development, mostly without a clear planning for local employment, or alternative means of transportation. Transport sector accounts for 14% of Australia’s net greenhouse gas emissions. Without further policy action, Australia’s emissions are projected to continue to increase. The Australian Federal Government and the new Department of Climate Change have recently published a set of maps showing that rising seas would submerge large parts of Victoria coastal region. Such event would lead to major disruption in planned urban growth areas in the next 50 years with broad scale inundation of dwellings, facilities and road networks. The Greater Geelong Region has well established infrastructure as a major urban centre and tourist destination and hence attracted the attention of federal and state governments in their quest for further development and population growth. As a result of its natural beauty and ecological sensitivity, scenarios for growth in the region are currently under scrutiny from local government as well as development agencies, scientists, and planners. This paper is part of a broad research in the relationship between transportation system, urban form, trip demand, and emissions, as a paramount in addressing the challenges presented by urban growth. Progressing from previous work focused on private cars, this present paper investigates the use of public transport as a mode for commuting in the Greater Geelong Region. Using a GIS based interaction model, it characterises the current use of the existing public transportation system, and also builds a scenario of increased use of the existing public transportation system, estimating potencial reductions in CO2 emissions. This study provides an improved understanding of the extent to which choices of transport mode and travel activity patterns, affect emissions in the context of regional networks. The results indicate that emissions from commuting by public transportation are significantly lower than those from commuting by private car, and emphasise that there are opportunities for large abatment in the greenhouse emissions from the transportation sector related to efforts in increasing the use of existing public transportation system.

Lost in Hanoi : disorientation, travel, and urban space

Using a 2010 trip to Hanoi, Vietnam, this article looks at the ways that disorientation is used as a  trope within the urban environment and to create the traveling subject. Suggesting that travel is a form of deliberate disorientation/ orientation, the article focuses on ideas of disorientation within the urban environment and the ways they have been portrayed in Western cultural forms (the flâneur; the dérive) while suggesting these forms are not sufficient to understand the dynamics of travel. Moreover, the article focuses on two forms of travel as disorientation derived from John Zilcosky—the trope of being “lost and found” and that of  “the return.” Finally, the article suggests that Marcus Auge’s idea of non-place is not only a sufficient way of conceptualizing contemporary notions of travel, but is also an indicator of something beyond its scope—that of globalization.

Identifying the extent, motivations and barriers to outsourcing of accounting services

In this paper we analyse the oursourcing of accounting services. The extent to which firms are currently outsourcing, or considering outsourcing such services, and the motivations and barriers associated with outsourcing are identified. Empirical data from a random sample of accounting firms are used in this analysis. Data indicate that the majority of accounting firms are either currently outsourcing or considering outsourcing and that they exopect the volume of oursourced services to increase. In contrast to the scholarly literature advocating labor arbitrage as the primary driver for organizations choosing to outsource, in this study it was found that the main factors underpinning the decision to outsource were the expediting of service delivary to clients, and to enable the firm to focus on its core competencies.

Evaluating the travel, physical activity and carbon impacts of a 'natural experiment' in the provision of new walking and cycling infrastructure : methods for the core module of the iConnect study

Introduction Improving infrastructure to support walking and cycling is often regarded as fundamental to encouraging their widespread uptake. However, there is little evidence that specific provision of this kind has led to a significant increase in walking or cycling in practice, let alone wider impacts such as changes in overall physical activity or carbon emissions. Connect2 is a major new project that aims to promote walking and cycling in the UK by improving local pedestrian and cycle routes. It therefore provides a useful opportunity to contribute new evidence in this field by means of a natural experimental study.

Methods and analysis iConnect is an independent study that aims to integrate the perspectives of public health and transport research on the measurement and evaluation of the travel, physical activity and carbon impacts of the Connect2 programme. In this paper, the authors report the study design and methods for the iConnect core module. This comprised a cohort study of residents living within 5 km of three case study Connect2 projects in Cardiff, Kenilworth and Southampton, supported by a programme of qualitative interviews with key informants about the projects. Participants were asked to complete postal questionnaires, repeated before and after the opening of the new infrastructure, which collected data on demographic and socioeconomic characteristics, travel, car fuel purchasing and physical activity, and potential psychosocial and environmental correlates and mediators of those behaviours. In the absence of suitable no-intervention control groups, the study design drew on heterogeneity in exposure both within and between case study samples to provide for a counterfactual.

Ethics and dissemination The study was approved by the University of Southampton Research Ethics Committee. The findings will be disseminated through academic presentations, peer-reviewed publications and the study website (http://www.iconnect.ac.uk) and by means of a national seminar at the end of the study.

Prediction intervals to account for uncertainties in travel time prediction

The accurate prediction of travel times is desirable but frequently prone to error. This is mainly attributable to both the underlying traffic processes and the data that are used to infer travel time. A more meaningful and pragmatic approach is to view travel time prediction as a probabilistic inference and to construct prediction intervals (PIs), which cover the range of probable travel times travelers may encounter. This paper introduces the delta and Bayesian techniques for the construction of PIs. Quantitative measures are developed and applied for a comprehensive assessment of the constructed PIs. These measures simultaneously address two important aspects of PIs: 1) coverage probability and 2) length. The Bayesian and delta methods are used to construct PIs for the neural network (NN) point forecasts of bus and freeway travel time data sets. The obtained results indicate that the delta technique outperforms the Bayesian technique in terms of narrowness of PIs with satisfactory coverage probability. In contrast, PIs constructed using the Bayesian technique are more robust against the NN structure and exhibit excellent coverage probability.

Insights into international travel by students

Although research on international travelers abounds in the literature, international travel by students remains a neglected area of research. This article reports the findings from a survey of 370 university students in New Zealand. The survey identified student motives for undertaking international travel, the planning process, and the preferred destinations and methods of financing international trips. Logit models were developed and estimated for two important aspects of international travel by students. In addition, the study also included cross-cultural comparisons of travel behavior. The findings indicate that students traveling overseas represent a distinct market with specific needs and preferences. Travel behaviors vary significantly for different cultures and the article shows that it is possible to model such behaviors.

Crowdsourcing motivations in a not-for-profit GLAM context : the Australian newspapers digitisation program

Crowdsourcing in recent times has become popular among not-for-profits as a means of eliciting members of the public to contribute to activities that would normally have been carried out by staff or by contracting external expertise. The GLAM (galleries, libraries, archives, museums) sector does have a history of involving online volunteers (e.g. reviewing books). Extending that tradition, some GLAM institutions are engaging in crowdsourcing projects to enhance and enrich their collections. But what motivates the public to participate in these crowdsourcing activities? Understanding the unique motivations of participants is needed to establish a motivational framework for GLAM organisations in their not-for-profit context. We present findings from a study of the motivational factors affecting participation in the Australian Newspapers Digitisation Program (ANDP) by the National Library of Australia (NLA). Based on motivational theories and frameworks the study shows that the participants are motivated by a complex framework of personal, collective and external factors. Participants were highly intrinsically motivated, but valued altruistic and community motivations as well. Community and external factors played a vital role in their continued involvement. The paper concludes with a conceptual framework of the motivational factors for crowdsourcing participants in a GLAM context based on the motivational dynamics observed in the ANDP case.

Understanding pentecostal motivations for undertaking community development in South East Asia : evidence of an expanded understanding of holistic mission

A shift has been observed in the activities of by Western-based, pentecostal mission organisations in mainland South East Asia. Where once these mission organisations avoided formal community development programs as a distraction to their understanding of mission, the funding for and implementation of such programs has increased dramatically in recent times. This shift in focus is best understood by considering motivations and changing pentecostal perceptions of mission. The research is based on new primary data collected through interviews with long-term and senior pentecostal mission practitioners engaging in development projects in mainland South East Asia. It explores their motivations for engaging in community development, and in particular the extent to which community development programs are seen as a strategy for proselytisation as compared the extent to which they are conducted out of other humanitarian motivations. Analysis of this data challenges preconceived notions of proselytisation being the primary motive of pentecostal mission agencies, and demonstrates a more holistic idea of mission.

Helping others or a rewarding career? Investigating student motivations to train as social workers in England

• Summary: Understanding why people want to be social workers is important both for developing social work education and for the profession as a whole. This article presents evidence about the motivations of students enrolled on social work degree programmes in England and draws on data from 3000 responses of three successive intakes of students responding to six online surveys and 26 focus group interviews involving 168 students from nine different social work programmes in six case study sites. The article locates these data in the context of earlier studies of social workers’ motivations, the changing policy context and the changes introduced by the new degree.

• Findings: Similar to previous studies, the current analysis shows that altruistic motivations dominated, but students were also influenced by career issues and the day-to-day aspects of social work. The data highlight continuities with the former qualification in social work in the UK (the DipSW) and provide evidence that the introduction of the social work degree has not dramatically changed the underlying motivations of social work students.

• Applications: Understanding student motivations is important in terms of recruitment to social work qualifying programmes and subsequent retention within the profession. Social work educators and employers need to pay attention to the consequences of mismatches between motivations and expectations about what professional practice involves.
