Moving Home: Gender, Place, and Travel Writing in the Early Black Atlantic
No full textIn Moving Home, Sandra Gunning examines nineteenth-century African diasporic travel writing to expand and complicate understandings of the Black Atlantic. Gunning draws on the writing of missionaries, abolitionists, entrepreneurs, and explorers whose work challenges the assumptions that travel writing is primarily associated with leisure or scientific research. For instance, Yoruba ex-slave turned Anglican bishop Samuel Ajayi Crowther played a role in the Christianization of colonial Nigeria. Sarah Forbes Bonetta, a formerly enslaved girl "gifted" to Queen Victoria, traveled the African colonies as the wife of a prominent colonial figure and under the protection of her benefactress. Alongside Nancy Gardiner Prince, Martin R. Delany, Robert Campbell, and others, these writers used their mobility as African diasporic and colonial subjects to explore the Atlantic world and beyond while they negotiated the complex intersections between nation and empire. Rather than categorizing them as merely precursors of Pan-Africanist traditions, Gunning traces their successes and frustrations to capture a sense of the historical and geographical specificities that shaped their careers.Sandra Gunning is Professor of American Studies and Afroamerican and African Studies at the University of Michigan, Ann Arbor, author of Race, Rape, and Lynching: The Red Record of American Literature, 1890–1912 and coeditor of Dialogues of Dispersal: Gender, Sexuality, and African Diasporas.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/170929/1/Gunning_MovingHome_9781478092636.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/170929/2/Gunning_MovingHome_frontcover.jpgDescription of Gunning_MovingHome_9781478092636.pdf : TextDescription of Gunning_MovingHome_frontcover.jpg : CoverSEL
Detection of gases and gas mixtures by correlation spectroscopy
No full textThe reliable detection and monitoring of gases and gas mixtures is known to play a crucial role in many real-world environmental and industrial applications. It is of considerable importance to utilise techniques that are not susceptible to poisoning, are specific to a target gas in a mixture, are unaffected by contaminants, and can be adapted for in-process monitoring. Ever-more stringent requirements in this field dictate a need for ongoing research in this area. As many common gases exhibit their fundamental optical absorption in the infra-red and visible regions, novel optical absorption methods for the detection of gases and gas mixtures have application in a variety of real-world situations. Of these, correlation spectroscopy is an established non-dispersive technique that is attractive in offering appreciable sensitivity and discrimination for gas detection, with the potential for real-time measurement of different gas species within a mixture using a single sensing instrument. We present new results for the detection of O2, CO, and CO2 gases using a method of real-time correlation spectroscopy involving the modulation of the absorption spectrum of a reference gas sample relative to that of the gas to be measured. We believe it is the first time O2 has been sensed in this manner and the use of low-cost sources and detectors suggests attractive commercial potential for this device. <br/
Growth and Risk: Methodology and Micro Evidence
No full textThere has been a revival of interest in the effect of risk on economic growth. We quantify both ex ante and ex post effects of risk using a stochastic version of the Ramsey model. We develop a simulation-based econometric methodology which allows us to estimate the model in the structural form suggested by theory. The methodology is applied to micro data from a remarkable long-running panel data set for rural households in Zimbabwe. We find that risk substantially reduces growth: in the ergodic distribution the mean (across households) capital stock is 46% lower than in the absence of risk. About two-thirds of the impact of risk is due to the ex ante effect (i.e. the behavioral response to risk) which is usually not taken into account in policy design. Our results suggest that the e¤ectiveness of policy interventions which reduce exposure to shocks or help households in risk management may be seriously underestimated.Farm household models, stochastic Ramsey growth models, estimation by simulation.
Assessing environmental footprints induced by geo-energy exploitation: the shale gas case
No full textThis Special Issue describes the main outcomes from the SHEER (SHale gas Exploration and Exploitation induced Risks)
project, a 3 year EC Horizon 2020 funded investigation into environmental risk associated with shale oil and gas development
within the European Union. A key feature of the programme of work has been the independent monitoring of a shale
gas well at Wysin, Poland, through a network of seismic, groundwater and air quality measurement arrays and shallow
borehole sensors both in advance of and subsequent to hydraulic fracturing operations. In conjunction with the environmental
monitoring programme, a multi-hazard risk assessment technique has been applied to shale gas operations to identify
and assess the likelihood of occurrence of incidents and their potential impacts on the surrounding environment. Given the
limited development of shale oil and gas in Europe experience out-with the European Union, particularly in the USA and
Canada, has been integrated into the project. A further element of the research has been the dissemination of results through
academic publications, a large number of presentations to conferences and at SHEER events in Italy, Poland and the UK.
This introductory paper provides a brief synopsis of the research and development that has been carried out, with a primary
focus on the best practice recommendations, policy guidelines and key learning that have been developed during the course
of the project. Policy guidelines include issues of relevance to regulators and government in providing effective regulatory
oversight of shale gas operations within the European Union. Recommendations for best practice are primarily related to the
monitoring and evaluation of environmental risk in the development of shale gas within the European Union
