John Muir has long been known as a significant figure in the history of conservation, including for promoting the recognition of the Yosemite Valley in the Sierra Nevada Mountains of California as a national park by the American people and government. Muir is known particularly for his pivotal involvement in the establishment of the Sierra Club, one of North America’s leading conservation associations. His place in the history of biogeography has been largely unrecognized, although a reading of his books shows that there is a rich seam of innovative historical and ecological biogeographical ideas resulting from his many years living in the Sierras. Added to Muir’s interests in the Sierra Mountains and the Sierra Club were his explorations of the mountain ranges and forests of Alaska, as well as his near world‐wide travels to Europe, Asia, Africa, South America and the Pacific. The literature on biogeography has remained very largely isolated from Muir’s writing, a dissociation that the present paper seeks to remedy.  相似文献

D'Arcy Thompson was a biologist, a mathematician and a classicist. His writing was great literature as well as great science. He is primarily known for a single book--On Growth and Form--and indeed for a single chapter within it, on his 'theory of transformations', which shows how the differences between the forms of related species can be represented geometrically. This theory cries out for causal explanation, which is something the great man eschewed. Perhaps the time is close when comparative developmental genetics will be able to provide such an explanation.  相似文献

This paper seeks to reinterpret the life and work of J. B. S. Haldane by focusing on an illuminating but largely ignored essay he published in1927, “The Last Judgment” – the sequel to his better known work, Daedalus (1924). This astonishing essay expresses a vision of the human future over the next 40,000,000 years, one that revises and updates Wellsian futurism with the long range implications of the “new biology” for human destiny. That vision served as a kind of lifelong credo, one that infused and informed his diverse scientific work, political activities, and popular writing, and that gave unity and coherence to his remarkable career.

Tracing the contributions of Edgar Anderson (1897--1969) of the Missouri Botanical Garden to the important discussions in evolutionary biology in the 1940s, this paper argues that Anderson turned to corn research rather than play a more prominent role in what is now known as the Evolutionary Synthesis. His biosystematic studies of Iris and Tradescantia in the 1930s reflected such Synthesis concerns as the species question and population thinking. He shared the 1941 Jesup Lectures with Ernst Mayr. But rather than preparing his lectures as a potentially key text in the Synthesis, Anderson began researching Zea mays -- its taxonomy, its origin, and its agronomic role. In this study, Anderson drew on the disciplines of taxonomy, morphology, genetics, geography, anthropology, archaeology, and agronomy among others in his own creative synthesis. Though his maize research in the 1940s represented the most sustained work of his career, Anderson was also drawn in many directions during his professional life. For example, he enjoyed teaching, working with amateurs, and popular writing. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

This article presents glimpses of the life and fieldwork of Grant Evans, the foremost anthropologist and historian to work on Laos in recent decades. It explores his youth in rural Australia, his tumultuous student years, and the challenges he faced as a professional scholar negotiating the Lao PDR bureaucracy. It draws insights from some of his early writing for alternative publications in Australia, as well as extensive discussions and correspondence with family, friends, professional counterparts and former students. It identifies factors in Grant's early life that were instrumental in his ability to research the Lao PDR. Ultimately, Grant possessed wide‐ranging academic and non‐academic interests. He was highly respected as a scholar and was a very decent human being.  相似文献

Robert Chambers and Thomas Henry Huxley helped popularize science by writing for general interest publications when science was becoming increasingly professionalized. A non-professional, Chambers used his family-owned Chambers' Edinburgh Journal to report on scientific discoveries, giving his audience access to ideas that were only available to scientists who regularly attended professional meetings or read published transactions of such forums. He had no formal training in the sciences and little interest in advancing the professional status of scientists; his course of action was determined by his disability and interest in scientific phenomena. His skillful reporting enabled readers to learn how the ideas that flowed from scientific innovation affected their lives, and his series of article in the Journal presenting his rudimentary ideas on evolution, served as a prelude to his important popular work, Vestiges of the Natural History of Creation. Huxley, an example of the new professional class of scientists, defended science and evolution from attacks by religious spokesmen and other opponents of evolution, informing the British public about science through his lectures and articles in such publications as Nineteenth Century. He understood that by popularizing scientific information, he could effectively challenge the old Tory establishment -- with its orthodox religious and political views -- and promote the ideas of the new class of professional scientists. In attempting to transform British society, he frequently came in conflict with theologians and others on issues in which science and religion seemed to contradict each other but refused to discuss matters of science with non-professionals like Chambers, whose popular writing struck a more resonant chord with working class readers.

This paper was prepared in honor of Marcel Florkin's eightieth birthday, before which he was stricken. Professor Florkin did attain, or rather had bestowed upon him, leadership in several areas of science, especially biochemistry. In his writing, in his editorships, in his organizational activities, and in his investigations he stressed meaningful overviews as well as accurate specialization. He understood the nature of the demanding efforts required to attain significant insight. All who knew him personally recall a thoughtful, friendly, occasionally jolly, personality. He epitomized the senior statesman of science. He will be sorely missed, and long remembered.  相似文献

Not so long ago I happened to treat a Jewish eighth-grade gymnasium student brought to Petrograd from a province. It was fall and the following spring he was to take his qualifying examinations. The young man, who belonged to a prosperous family, had brilliant abilities and graduated from each class with excellent grades—what would you think his illness was? He suffered—in his own words—from the throes of creative writing. Days and nights he poured over a notebook with his compositions in search of the best form to express his thoughts. Only after applying incredible efforts could one tear him away from his note-books and send him to bed at five or six o'clock in the morning, and this happened on a daily basis. With each day his mental health grew worse. It was clear that the young man undermined his health by overstudying, and that he had reached the point where he needed to worry about his health, not his studies, because a serious mental illness was descending upon him. The young man was well liked by everyone in his high-school. The teachers considered him the best student, and having learned about his illness, they promised to petition to grant him the right to graduate from school without the final examination and with a certificate of excellent. But none of that helped. The young man could not relax, spending days and nights over his compositions and constantly tormenting himself with his "throes of creative writing."  相似文献

Matt Ridley, the science writer, is married to Anya Hurlbert, reader in visual neuroscience at the University of Newcastle. She studied physics at Princeton University as an undergraduate, then went to Cambridge University as a Marshall Scholar, where she took a Part III diploma in theoretical physics and an MA in physiology. She returned to the States to do the HST MD-PhD program at Harvard-MIT, studying with Tomaso Poggio for her PhD. Matt trained as a zoologist at Oxford, and after completing his PhD on the mating habits of the pheasant, turned to journalism. They met when, as science editor for The Economist, Matt interviewed Anya, and they married while he was the magazine's Washington correspondent. They moved to England, she to Oxford for postdoctoral research, he to become American editor of The Economist. After writing as a columnist for the Daily Telegraph and other papers, Matt turned to writing books: his titles include The Red Queen, The Origins of Virtue, Genome and Nature via Nurture. They now live in rural Northumberland with their two children.  相似文献

Jules Cotard was a psychiatrist at the Vanves asylum. Described as a sharp observer and clinician, he also had a passion for clinical research. Jules Cotard was always ready to modify, question, or even abandon a hypothesis if clinical facts and scientific analysis made him deem it necessary to do so. He devoted most of his writing to “negation delirium”, (also known as “nihilistic delusion”): “Du délire hypochondriaque dans une forme grave de mélancolie (“Concerning hypochondriac delusion in serious melancholy”)” in 1880, “Du délire des négations (“Concerning negation delirium”)” in 1882, “Perte de la vision mentale dans une mélancolie anxieuse (“Loss of mental vision in anxious melancholy”)” in 1884 and “Du délire d’énormité (“Concerning delusions of enormity”)” in 1888. Long after his death, there was much controversy and debate about the existence of negation delirium. J. Séglas and J. Régis were the main contributors to the development and clarification of his work. Thus it is this most unusual of syndromes, Cotard’s syndrome, that has caused Jules Cotard to be part of the history of French psychiatry since the end of the 19th century.  相似文献

Mitchell's formulation of the chemiosmotic theory of oxidative phosphorylation in 1961 lacked any experimental support for its three central postulates. The path by which Mitchell reached this theory is explored. A major factor was the role of Mitchell's philosophical system conceived in his student days at Cambridge. This system appears to have become a tacit influence on his work in the sense that Polanyi understood all knowledge to be generated by an interaction between tacit and explicit knowing. Early in his life Mitchell had evolved a simple philosophy based on fluctoids, fluctids and statids which was developed in a thesis submitted for the z at the University of Cambridge, England. This aspect of his work was rejected by the examiners and became a tacit element in his intellectual development. It is argued from his various publications that this philosophy can be traced as an underlying theme behind much of Mitchell's theoretical writing in the 50's leading, through his notion of vectorial metabolism, to the formulation and amplification of the chemiosmotic theory in the sixties. This philosophy formed the basis for Mitchell of his understanding of biological systems and gave him his unique approach to cell biology.

Adding a strong conclusion can alter a cookbook lab into an inquiry lab by challenging the student to defend relevant data and clearly communicate his or her findings. A well-organized scoring guide makes it easier for students to understand what is involved in writing a strong conclusion. Examples of student writing that are accompanied with the scoring guide are shown. A framed conclusion for younger grades or special-needs students is also included.  相似文献

A gift from a patient drew Hope, BC, family physician Gerd Asche irrevocably into the local medical history of the 1858 Fraser River Gold Rush. Because of his interest in Dr. Max William Fifer, Asche undertook research missions in British Columbia, England and the US, converted his computer room to a research and writing centre, and wrote a biography of his predecessor and colleague. He recounts his experience and the growing satisfaction provided by his interest in medical history.  相似文献

The paper discusses A.W. Howitt's position as an amateur of science in colonial Gippsland, and explores connections between his geological and anthropological endeavours. Two contexts contributed to the kind of anthropology he did. and the kinds of works he wrote. One is the point on the trajectory of the colonial history of Victoria when Howitt joined it and began his researches. The other is the moment in the development of anthropology when he and his sister Anna Mary Howitt began to read and correspond about the discipline, and he began to correspond with other practitioners. Geology was linked to Howitt's anthropology in two ways: through his working life in Gippsland, and in models that informed the evolutionary paradigm within which his anthropological research and writing were situated.  相似文献

The title of this essay sets its dialogic structure. Ronald Berndt's writing at times obscured the core insights that he had about Yolngu society, and partly as a consequence Australian anthropology has not yet made the best use of the immense richness of his ethnographic legacy. In retrospect, in many areas of their research the Berndts were pioneers addressing themes and topics that had been for too long ignored. They opened up new fields of study and redressed some of the imbalances associated with functionalism, the dominant paradigm of their early years as anthropologists. In this essay I examine two areas of Ronald Berndt's writings in which he had insights that were not fully appreciated at the time: the analysis of Yolngu social organisation and the analysis of Yolngu sexual symbolism. In both cases, his absorption in Yolngu ethnography made him aware that his predecessors had overlooked important themes of Yolngu society, yet in both cases his analysis was less convincing than it might have been.  相似文献

This paper is a critique of certain moral perspectives that are found in the second edition of Engelhardt's Foundation of Bioethics. These views are spelled out in explicit detail in his second edition, and follow on the heels of a profound religious conversion. Engelhardt is an eminent bioethicist with strong religious convictions that overlay much of his writing. The author wishes to question some of the conclusions that Engelhardt reaches as they touch upon moral frameworks, pluralism, and a 'secular' bioethics.  相似文献
