Multi‐Domain User‐Generated Content Based Model to Enrich Road Network Data for Multi‐Criteria Route Planning

By utilizing today's web‐based technologies, people can act as sensors and share their perceptions, emotions and observations in a variety of data forms, such as images, videos, texts, Global Positioning System (GPS) trajectories and maps. These forms are collectively called user‐generated content (UGC). These data are in different domains and have a multi‐modality nature. Although recent efforts have probed the acquisition of local knowledge by using single‐domain UGC data in specific applications, such efforts have not thus far presented a model considering multi‐domain UGC specifically to enrich road network data. This article aims at presenting such a model wherein, with the help of each data domain of UGC, one aspect of people knowledge about the road segment is obtained. These different aspects of knowledge are integrated using a Skyline operator to support multi‐criteria route finding. We name this model ERSBU (enriching road segments based on UGC). In ERSBU, road segments are basic spatial units, and their subjective properties have been extracted by using available UGC. The scenic score for each road segment was computed by using geo‐tagged Panoramio photos. The accessibility level of each road segment to different facilities was calculated based on data captured from Wikimapia and OpenStreetMap. Moreover, for measuring the movement popularity of each road segment, Wikiloc and Everytrail GPS trajectories were utilized. For the implementation of the ERSBU model, Tehran region 6 was considered the case study area. The Evaluation of the results proved that road segments that achieved a high score based on knowledge extracted from UGC also mostly gained top scores by analyzing traditional maps. ERSBU allows users to accomplish more‐qualitative path finding by considering the multi‐view characteristics of road segments.     

Regulatory Reform and the Management of Intergovernmental Relations in Australia

There have been three waves of regulatory reform in Australia since the 1980s, each informed by broadly similar neoliberal political and economic objectives, but with important differences of emphasis that reflect key priorities and changing contexts. This article argues that the second and third waves brought with them three significant developments: (1) A substantially enhanced capacity for the organisation and management of intergovernmental relations in Australia; (2) a new, national emphasis on the need for microeconomic reform, reinvigorated and broadened in the third wave by a broadening of the national ‘productivity and efficiency’ debate through the Human Capital agenda of Council of Australian Governments (COAG); and (3) markedly changed funding and policy responsibilities between the levels of government. These changes include new arrangements for intergovernmental funding; a new performance oversight body, the COAG Reform Council; a revised Intergovernmental Agreement on Federal Financial Relations; and a new role for Commonwealth ministers in chairing COAG working parties.

Producing North and South: a political geography of hydro development in Québec

Since the 1970s, the tapping of James Bay's hydroelectric potential has been synonymous with the tapping of divergent national imaginaries for native and non-native people in Québec. Exploitation of natural resources in the region has activated different narratives of political identity for each community. I explore this evolving political context by examining how, for each group, water has emerged simultaneously as a physical entity possessing economic value and a social artefact supporting the consolidation of national boundaries. I do so by analysing three phases of changing relationships around resource management, namely: hydroelectric development on the La Grande river in the 1970s; the Cree opposition to Great Whale in the 1990s; and the recent agreement concerning a new relationship between the two parties. In each of these phases, nature has been both the symbolic and material tie that binds different national identities and materialises their boundaries. While these are not boundaries in the traditional geopolitical understanding of the term, the forging of an equitable framework of development in the region depends on the recognition of nature as a historical and political formation that answers to different sets of national preoccupations.     

A Route Map for Successful Applications of Geographically Weighted Regression

Geographically Weighted Regression (GWR) is increasingly used in spatial analyses of social and environmental data. It allows spatial heterogeneities in processes and relationships to be investigated through a series of local regression models rather than a single global one. Standard GWR assumes that relationships between the response and predictor variables operate at the same spatial scale, which is frequently not the case. To address this, several GWR variants have been proposed. This paper describes a route map to decide whether to use a GWR model or not, and if so which of three core variants to apply: a standard GWR, a mixed GWR or a multiscale GWR (MS-GWR). The route map comprises 3 primary steps that should always be undertaken: (1) a basic linear regression, (2) a MS-GWR, and (3) investigations of the results of these in order to decide whether to use a GWR approach, and if so for determining the appropriate GWR variant. The paper also highlights the importance of investigating a number of secondary issues at global and local scales including collinearity, the influence of outliers, and dependent error terms. Code and data for the case study used to illustrate the route map are provided.

‘Main Bhi to Hindostaan Hoon’: gender and nation-state in India’s Border Roads Organisation*

In this ethnography of India’s border roads, I follow the circular/seasonal journeys of migrant road labourers from Jharkhand to the upper reaches of the Himalayas and back. I pay particular attention to the notions of masculinity and nation-building as they reveal themselves in their travel narratives. These migrants travel every May to work as road construction labour for the Border Roads Organisation (BRO) of India working in the Himalayan frontiers. While the BRO advertises its roles through various road signs claiming to be ‘creating, connecting and caring’ (for) the nation – it is the ambivalent construction of the labourers gendered national subjectivities emerging in the narratives of and about the migrant labour that is of particular interest to this article. One of the central contributions of this article is to show how hierarchical domains of the nation and the hierarchical structures within masculinity intersect and rely upon each other to build gendered national subjects. This research is based on over five years of a very mobile ethnography.

An alternative classification of Australian elections

Attempts have been made to apply to Australia the classification of elections developed by researchers at the University of Michigan. However, the American model is not suitable for Australian elections on a number of grounds. An alternative classification of Australian elections could be made by modifying the basic scheme developed for New Zealand elections.     

A Speculative Model of Population Influences on Australian Ecology,Economy and Society

A lack of empirical data and sufficient conceptual frameworks precluded the 1994 national population inquiry from proposing demographic targets for the future ‘carrying capacity’ of Australia. A speculative model is proposed here of population impacts in the ecological, economic, social and relational domains. The model is ‘run’ under scenarios of growing and stable population so that key interactions can be explored and thereby advance debate about broader population policy in Australia.     

清代新疆冰岭道建置考

冰岭道作为乾隆平回之后为屯田伊犁而设的首条官方台路,其重要性自不待言。然而,长期以来,学界对这一问题的研究却较为缺乏。近年来,虽有学者对冰岭道做了专门探讨,但对于此路最为重要且变化最为剧烈的建置初期的情形,却由于汉文史料的匮乏而论述简略,考证失实。有鉴于此,本文在吸收前人经验的基础上,充分利用满汉文史料,对冰岭道的建置情形进行了考察。首先,证实了冰岭道建置初期并非仅有两阶段,而是有着层次分明的三个阶段。其次,对三阶段中所设台站的兴废增减进行了梳理,并阐明其调整过程不仅反映了台站职能的变化,更体现了清廷对新疆统治思想的变迁。最后,考证出伊犁驻防建设初期,伊犁地区与外界沟通的官方台路仅有冰岭道一条。     

STRUCTURAL IMPERATIVES BEHIND RACIAL CHANGE IN BIRMINGHAM, ALABAMA

While it is agreed that capital made use of race to restructure for more profitable production, there have been few attempts to incorporate race within the general framework of historical materialist inquiry and class politics. This paper discusses the social construction of race in Birmingham, Alabama for the industrial, Fordist, and post-Fordist phases of U.S. capitalist development. No other industrial city in America would rely upon black labor so early in its industrial development as Birmingham, providing the opportunity to examine the social construction of race from an early stage of industrial capitalism. While southern periodizations of capitalist development correspond in some ways to those of the regulationists, they also diverge in other important ways, precisely because the southern road to capitalism was different, defining the path for the entry of blacks into capital-labor relations.

The Nature and Genesis of the Peutinger Map

The place of the Peutinger map in the history of both ancient and medieval geography and cartography is controversial. Many basic questions as to its sources, dating and purpose remain unanswered. In the light of various pieces of new evidence these problems are reassessed. It is argued that the Peutinger map does derive from a Roman original but that, without precedent in Roman cartography or impact on later medieval cartography, the mapping of itinerary data onto a base map of the oecumene is likely to be a genuine innovation of the designer of the archetype. There is no need to suppose the map to be an officially state‐sponsored product. The sources relied upon were commonly available and would have been familiar to the public in late antiquity. The purpose of the map is more likely to have been ornamental than practical. It is impossible to determine a precise date or location for the creation of the archetype, but the cultural viewpoint embodied in the map is undoubtedly antique, Latin and western.     

Assessing Australia’s options in the context of Brexit: engaging with the UK and the European Union

ABSTRACT

The Brexit vote will fundamentally transform the European Union (EU) and will change how the UK relates to Europe and the rest of the world. What are the implications for Australia at this critical juncture? The UK has been a major player in the Australia–EU relationship, and Australia will now need to recalibrate its approach to both the UK and the EU across a range of policy areas. This article examines the future of Australia–UK and Australia–EU relations in the wake of Brexit, and assesses Australia’s options going forward. The authors advance three considerations. Firstly, Australia’s national interests are best served by adopting a pragmatic rather than nostalgic approach towards future relations with the UK and the EU. Secondly, Australia should avoid pursuing one relationship at the expense of the other and creating a zero-sum dynamic. Finally, Australia’s future strategy must consider broader global developments, such as events within its own region and the US presidency.

Electoral politics in the Australian Journal of Political Science: A review

Australia’s constant experimentation with electoral system design, and its effects on voter behaviour, have been consistent themes in the Australian Journal of Political Science and its predecessor, Politics, for half a century. This article examines this research in the context of three areas: electoral institutions; election campaigns; and voter behaviour. Three distinct stages in the research are identified, starting with basic fact-gathering, then progressing to the application of rigorous methods and evidence to real-world questions. In the third stage, scholarly attention has been devoted to placing Australia within a comparative framework. An underlying theme in the research is Australian exceptionalism in electoral politics.

Human security in Australia: public interest and political consequences

The new human security paradigm has reconceptualised security beyond traditional physical threats to encompass ‘lifestyle’ concerns, such as health and environmental security. This article uses national survey data collected in Australia in 2007 to examine how public opinion views this new paradigm and to evaluate its political consequences. The results show that the public makes a clear distinction between all four types of human security—health, the environment, national security and the economy. Longitudinal analysis shows that health and the environment have gained greater prominence with the public since 1990. Each dimension of human security has only limited roots in the social structure. However, each has important consequences for the ideological orientation of the public, and for party support. The authors conclude that as ‘lifestyle’ concerns become more prominent for the public, parties of the right will have to adapt to the new paradigm in order to ensure that they are not electorally disadvantaged.     

Preparation of Engineering Geological Maps of Bam City Using Geophysical and Geotechnical Approach

Engineering geological mapping was carried out at a scale of 1:25000 in the city of Bam, located in southeastern Iran, to provide engineering geological information as a base for seismic microzonation of the city. In this study, Seismic Refraction and Vertical Seismic Profiling (VSP) surveys were employed along with boreholes in order to identify the characteristics of subsurface material in Bam city. A number of different kinds of maps of the city were prepared consisting of Iso-depth, Iso-velocity, and Iso-Poisson's Ratio maps. The study also involves trial pitting and continuous core recovery, in-situ, and laboratory tests. Borehole data, index properties of soils, and standard penetration test results were used to assess subsurface conditions. Geophysical and geotechnical data were combined to simulate geotechnical boreholes and prepare engineering geological maps to provide basic data for seismic geotechnical microzonation to facilitate in the reconstruction of the city of Bam.
