Abstract

Studies of the radical environmental politics of the 1960s have tended to downplay the extent to which much of that countercultural intellectual and social ferment continued into the 1970s and 1980s. Canadian Countercultures and the Environment adds to our knowledge of this understudied period. This collection contributes a sustained analysis of the beginning of major environmental debates in this era and examines a range of issues related to broad environmental concerns, topics which emerged as key concerns in the context of Cold War military investments and experiments, the oil crisis of the 1970s, debates over gendered roles, and the increasing attention to urban pollution and pesticide use.No other publication dealing with this period covers the wide range of environmental topics (among others, activism, midwifery, organic farming, recycling, urban cycling, and communal living) or geographic locales, from Yukon to Atlantic Canada. Together, they demonstrate how this period influenced and informed environmental action and issues in ways that have had a long-term impact on Canadian society.With contributions by:Matt CaversMegan DaviesNancy JanovicekAlan MacEachernDavid NeufeldRyan O'ConnorDaniel RossHenry TrimSharon Weaver

Abstract

A geographer with extensive research experience in the Canadian North, Jack D. Ives has written a lively and informative account of several expeditions to Baffin Island during the "golden age" of federal research. In the 1960s, scientists from the Geographical Branch of Canada's Department of Energy, Mines, and Resources travelled to Baffin to study glacial geomorphology and glaciology. Their fieldwork resulted in vastly increased knowledge of the Far North-from its ice caps and glaciers to its lichens and microfossils. Drawing from the recollections of his Baffin colleagues as well as from his own memories, Ives takes readers on a remarkable adventure, describing the day-to-day experiences of the field teams in the context of both contemporary Arctic research and bureaucratic decision making. Along the way, his narrative illustrates the role played by the Cold War-era Distant Early Warning Line and other northern infrastructure, the crucial importance of his pioneering aerial photography, the unpredictable nature of planes, helicopters, and radios in Arctic regions, and of course, the vast and breathtaking scenery of the North. Baffin Island encompasses both field research and High Arctic adventure. The research trips to Baffin between 1961 and 1967 also served as a vital training ground in polar studies for university students; further, they represented a breakthrough in gender equality in government-sponsored science, thanks to the author's persistence in having women permitted on the teams. The book contains a special section detailing the subsequent professional achievements of the many researchers involved (in addition to the later career moves of Ives himself) and a chapter that delves deeper into the science behind their fieldwork in the North. Readers need not be versed in glaciology, however. Ives has produced a highly readable book that seamlessly combines research and adventure.

Abstract

Declining access to fresh water is one of the twenty-first century’s most pressing environmental and human rights challenges, yet the struggle for water is not a new cause. The 8,800-kilometer border dividing Canada and the United States contains more than 20 percent of the world’s total freshwater resources, and Border Flows traces the century-long effort by Canada and the United States to manage and care for their ecologically and economically shared rivers and lakes. Ranging across the continent, from the Great Lakes to the Northwest Passage to the Salish Sea, the histories in Border Flows offer critical insights into the historical struggle to care for these vital waters. From multiple perspectives, the book reveals alternative paradigms in water history, law, and policy at scales from the local to the transnational. Students, concerned citizens, and policymakers alike will benefit from the lessons to be found along this critical international border.With contributions by Andrea Charron, Alice Cohen, Dave Dempsey, Jerry Dennis, Colin A.M. Duncan, Matthew Evenden, James W. Feldman, Noah D. Hall, Lynne Heasley, Nancy Langston, Frédéric Lasserre, Daniel Macfarlane, Andrew Marcille, Jeremy Mouat, Emma S. Norman, Peter Starr, Joseph E.

Abstract

Research on technology acceptance in educational contexts often shows little or no influence of user acceptance on use intention or use behavior. While recent attempts to factor in learners’ motivation appear promising, the problem of limited explanatory value of technology acceptance models remains. This paper further explores the relationship between motivational and acceptance factors in different learning contexts. Data (N = 673) from four studies conducted among users of two online learning environments at a major university in Germany are analyzed using a combined data set containing items relating to user motivation (according to Self-Determination Theory) and technology acceptance (according to the Unified Theory of Acceptance and Use of Technology). The data show significant differences in acceptance and motivational levels between these four groups, as well as a connection between acceptance and motivation. Implications of these results include a recommendation to revisit UTAUT assumptions and variables in future research.

Abstract

Water is usually referred to as the ‘Molecule of Life’. It constitutes the most abundant molecule in living (micro)organisms and is also essential for critical biochemical reactions, both for the global functioning and maintenance of Ecosystems (e.g., Photosynthesis) and individual (microbial) cells (e.g., ATP hydrolysis). However, most of Earth’s terrestrial environments present deficiencies in bioavailable water. Arid environments cover around a third of the land’s surface, are found on the six continents and, with the anthropogenic desertification phenomenon, will increase. Commonly defined by having a ratio of precipitation to potential evapotranspiration (P/PET) below 1, arid environments, being either hot or cold, are characterized by scant and erratic plant growth and low densities in macro-fauna. Consequently, these ecosystems are microbially mediated with microbial communities particularly driving the essential Na and C biogeochemical cycles. Due to the relatively simple trophic structure of these biomes, arid terrestrial environments have subsequently been used as ideal ecosystems to capture and model interactions in edaphic microbial communities. To date, we have been able to demonstrate that edaphic microorganisms (i.e., Fungi, Bacteria, Archaea, and Viruses) in arid environments are abundant, highly diverse, different from those of other terrestrial systems (both in terms of diversity and function), and are important for the stability and productivity of these ecosystems. Moreover, arid terrestrial systems are generally considered Mars-like environments. Thus, they have been the favored destination for astro(micro)biologists aiming to better understand life’s potential distribution and adaptation strategies in the Universe and develop terraforming approaches. Altogether, these points demonstrate the importance of significantly improving our knowledge in the microbial community composition (particularly for Fungi, Archaea and Viruses), assembly processes and functional potentials of arid terrestrial systems, as well as their adaptation mechanisms to aridity (and generally to various other environmental stresses). This Research Topic was proposed to provide further insights on the microbial ecology of hot and cold arid edaphic systems. We provide a detailed review and nine research articles, spanning hot and cold deserts, edaphic, rhizospheric, BSC and endolithic environments as well as culture-dependent and -independant approaches.

Abstract

It is now accepted that immune molecules are not only present within the brain during pathology but they exert physiological functions in the "healthy" brain as well. Increasing evidence points to a neuro-modulatory role of cytokines and chemokines (CHEMOtactic cytoKINES) in basal transmission and plasticity processes where signaling between peri-synaptic astrocytes, microglia and neurons plays an important role. Nevertheless, the exact mechanisms as to how cytokines, and in particular chemokines, participate in the molecular and cellular processes thought to subserve memory formation, plasticity processes and responsiveness to environmental stimuli remain to be clarified. Interestingly, in in vitro preparations, molecules like TNF-a, interleukin (IL)-1ß, IL-6, CX3CL1, CXCL12, CCL2 and CCL3 are implicated in synaptic formation and scaling, in modulation of glutamatergic transmission, in plasticity and neurogenesis, in particular in the hippocampus. The hippocampus is an extremely plastic structure, one of the main neurogenic niches in the adult brain, that exhibits a marked sensibility to environmental stimuli. Indeed exposure of mice to environmental enrichment (EE) modifies learning and memory abilities increasing neurogenesis and neuronal plasticity whether exposure to severe stressful experiences diminishes neurotrophic support, impairs neurogenesis, plasticity and cognition. In the hippocampus cytokines play a key role in mediating both positive as well as negative effects of the environment affecting neuronal plasticity also in stress related pathologies, such as depression. It has been reported that mice lacking type 1 receptor for IL-1 display impaired hippocampal memory and LTP that are restored by EE; moreover negative effects on neuronal plasticity (and thus behavior) induced by stress exposure can be prevented by blocking IL-1 activity. In addition, mice lacking IL-6 have improved cognitive functions whereas the absence of microglia-driven CX3CR1 signaling increases hippocampal plasticity and spatial memory occluding the potentiating effects of EE. However, the factors mediating the effect of environmental stimuli on behavior and plasticity has been only partially identified. Interestingly, it has been suggested that chemokines can play a key role in the flexibility of hippocampal structure and may modulate neuronal signaling during behavior. The question is how cytokines may translate environmental stimuli in plasticity and behavioral changes. This research topic is proposed to explore the role of cytokines, and more in particular chemokines, in the modulation of neuronal activity as a fundamental step for the correct brain wiring, function and susceptibility to environment. We encourage the submission of original research reports, review articles, commentaries, perspectives or short communications, in the following (but not limited to) topics:- Role of cytokines and chemokines in neuronal plasticity- Immune molecules and responsiveness to environment- Role of chemokine in the flexibility of hippocampal structure

Abstract

Golf is a major global industry. It is played by more than 60 million people worldwide, and there are more than 32,000 courses across the globe in 140 countries. This book looks at the power relationships in and around golf, examining whether the industry has demonstrated sufficient leadership on environmental matters for the government to be able to trust them to make decisions with implications for public health. It is the first comprehensive study of the varying impacts of golf on the environment, and is based on extensive empirical research, including interviews with major stakeholders in the golf industry and members of protest groups. The authors examine golf as a sport and as a global industry, drawing on three discrete literatures – the study of sport as a global social movement, environmental sociology and the study of corporate environmentalism.
