The beginnings of geography teaching and research in the University of Glasgow: the impact of J.W. Gregory

J.W. Gregory arrived in Glasgow from Melbourne in 1904 to take up the post of foundation Professor of Geology in the University of Glasgow. Soon after his arrival in Glasgow he began to push for the setting up of teaching in Geography in Glasgow, which came to pass in 1909 with the appointment of a Lecturer in Geography. This lecturer was based in the Department of Geology in the University's East Quad. Gregory's active promotion of Geography in the University was matched by his extensive writing in the area, in textbooks, journal articles and popular books. His prodigious output across a wide range of subject areas is variably accepted today, with much of his geomorphological work being judged as misguided to varying degrees. His 'social science' publications - in the areas of race, migration, colonisation and economic development of Africa and Australia - espouse a viewpoint that is unacceptable in the twenty-first century. Nonetheless, that viewpoint sits squarely within the social and economic traditions of Gregory's era, and he was clearly a key 'Establishment' figure in natural and social sciences research in the first half of the twentieth century. The establishment of Geography in the University of Glasgow remains enduring testimony of J.W. Gregory's energy, dedication and foresight

Photo-controlled permeation of spiropyran modified gramicidin A ion channel

Thesis (M.S.) University of Alaska Fairbanks, 2006Biomimetic devices show great potential as being molecular sensors of biological species. Gramicidin A (gA) is a well studied ionophore that can be easily modified at the C-terminus to be incorporated into phosphotidylcholine bilayer membrane systems. Potassium permeation of modified gA attached to spiropyran can be controlled with light. Upon ultra-violet irradiation spiropyran transforms to the more polar form merocyanine. The process back to spiropyran is completely reversible upon irradiation with 550 nm light or thermally. Free bilayer membrane vesicles are employed to describe the characteristics of modified ion channels. Characteristics of gA modified with spiropyran are described herein. A device has been created and characterized using electrochemical impedance spectroscopy to analyze potassium permeation through a tethered bilayer membrane system (tBMS) on a sheet of gold utilizing sulfur anchors. The device consists of a tethered phase and a mobile upper phase. The mobile lipid layer incorporates gA modified with spiropyran. The modification allows for control of potassium permeation across the tBMS. Impedance analysis shows good agreement with the ability to control potassium permeation to that of the free vesicle

All Things Reconciled: A Dialogue with Science from a Reformed Perspective

In this essay, the author examines some of the troubled interactions between science and religion in the West, attributing part of the trouble to a reliance upon anthropomorphic models of God and to an illusion of human separateness from the rest of creation. Citing recent findings of biology, neuroscience, and cognitive science, he argues that the human species is religious by its very nature
