Residential field courses are important and should be designed and delivered to maximize their value to students, staff and institutions. In this context, we use a novel approach involving analysis of the daily affective and conative reflections of students immersed in the field course experience to better understand student engagement with fieldwork. We show that students base their field course choice on a range of factors (costs and benefits) and that these choices subsequently influence student expectations and motivation to engage with fieldwork. We also show that the motivation of students to engage with fieldwork-based learning varies from person to person and from day to day. Our findings suggest that having a more nuanced understanding of the decisions students make when deciding which field course to enrol upon would enhance our ability to design attractive, accessible and useful field courses; that having an awareness of the expectations of students around field courses would enable us to better prepare them to undertake them; and that students are more motivated when they are afforded an opportunity to work independently and perceive themselves to have ownership of their learning.  相似文献

Roads have manifold social and environmental impacts, including regional development, social conflicts and habitat fragmentation. ‘Road ecology’ has emerged as an approach to evaluate the various ecological and hydrological impacts of roads. This article aims to complement road ecology by examining the socio‐spatial processes of road building itself. Focusing on the Brazilian Amazon, a heavily‐studied context due to forest fragmentation by roads, the authors consider non‐state social actors who build ‘unofficial roads’ for the purpose of gaining access to natural resources to support livelihoods and community development. They examine four case studies of roads with distinct histories in order to explain the socio‐spatial processes behind road building in terms of profit maximization, land tenure claims, co‐operative and conflictive political ecologies, and constraints as well as opportunities afforded by the biophysical environment. The study cases illustrate the need for a multi‐pronged theoretical approach to understanding road building, and call for more attention to the role of non‐state actors in road construction.  相似文献

In this article, we use a dynamic spatial microsimulation model of Britain for the analysis of the geographical impact of policies that have been implemented in Britain in the last 10 years. In particular, we show how spatial microsimulation can be used to estimate the geographical and socio-economic impact of the following policy developments: introduction of the minimum wage, winter fuel payments, working families tax credits, and new child and working credits. This analysis is carried out with the use of the SimBritain model , which is a product of a 3-year research project aimed at dynamically simulating urban and regional populations in Britain. SimBritain projections are based on a method that uses small area data from past Censuses of the British population in order to estimate small-area data for 2001, 2011, and 2021.  相似文献

ABSTRACT.  In this paper we employ dichotomous, multinomial and conditional logit models to analyze the employment-migration behavior of some 380,000 U.K. university graduates. By controlling for a range of variables related to human capital acquisition and local economic conditions, we are able to distinguish between different types of sequential migration behavior from domicile to higher education and on to employment. Our findings indicate that U.K. female graduates are generally more migratory than male graduates. We suggest that the explanation for this result lies in the fact that migration can be used as a partial compensation mechanism for gender bias in the labor market.  相似文献

Regulatory compliance has emerged as a central feature in the legitimization of the planning system, yet it remains relatively marginalized from academic scrutiny. This paper investigates the relationship between regulatory compliance and projects subjected to Environmental Impact Assessments (EIAs). It reviews, through an empirical field study, the levels of conformity with EIA driven planning approvals and considers, with the assistance of inputs from experienced professionals and theoretical perspectives of regulatory compliance how these might be improved.  相似文献

Geography: Shaping Australia's Future (2018) provides a ‘strategic plan’ for geography aligned with the national research priorities, as well other key areas where Australian geographers are addressing environmental and societal challenges. To provide context, we first describe the state of geography in Australian universities. We then articulate ways forward for strengthening Australian geography—both within the discipline and how we interact externally. We describe how geography may better contribute to policy agendas, capitalising on our unique perspectives of space, place and the environment, but also highlight how we might improve these contributions through a more unified approach across human and physical geography. Third, we discuss opportunities for geographers to build the reputation of the discipline and ways to advocate for its importance in the wider academy, school curricula and community. We conclude with some preliminary suggestions on how Australian geographers may better engage and contribute to the United Nations Agenda 2030 Sustainable Development Goals.  相似文献

Theodore Roosevelt circumvented Congress and expanded presidential power at the beginning of the 20th century, in part, by using the press to establish executive leadership of public opinion. This article describes how Roosevelt and his chief forester, Gifford Pinchot, launched a crusade in the press for Progressive conservation despite the opposition of congressmen who tried to block the use of publicists by executive agencies. Although Congress forbade the hiring of "publicity experts" in 1913, they were already common in executive agencies.  相似文献

Canada’s climate change strategy faces an uncertain future since the country’s withdrawal from the Kyoto Protocol in 2011, making domestic public debate and awareness critical in the search for effective mitigation policies. This article presents a spatio-temporal analysis of newspaper reporting across Canada on climate change and carbon reduction approaches, ranging from renewable energies (solar, wind, hydro power) to carbon management (e.g., carbon capture and storage [CCS]) and economic approaches (e.g., carbon trade, ecological fiscal reform). The findings of a news article keyword analysis show that the overall growth of the Canadian news coverage during this time period was significantly fragmented into isolated peaks of activity rather than continuous growth of the topic of climate change. Furthermore, the study finds a strong news emphasis on technology- and growth-oriented solutions as opposed to a comprehensive ecological modernization that would encourage a deeper structural discussion about Canada’s much-criticized carbon-intensive energy economy.  相似文献
