Archaeobotany is the study of plant remains from archaeological contexts. Despite Australasian research being at the forefront of several methodological innovations over the last three decades, archaeobotany is now a relatively peripheral concern to most archaeological projects in Australia and New Guinea. In this paper, many practicing archaeobotanists working in these regions argue for a more central role for archaeobotany in standard archaeological practice. An overview of archaeobotanical techniques and applications is presented, the potential for archaeobotany to address key historical research questions is indicated, and initiatives designed to promote archaeobotany and improve current practices are outlined. ,


What We Talk About When We Talk About The Soul, Stephen Asma May 2010

What We Talk About When We Talk About The Soul, Stephen Asma

Stephen T Asma

The author discusses the popularity among college students of the concept of the soul, and attempts to place it in its proper context. He dispenses with orthodox theological arguments and New Age arguments as scientifically untenable. He takes a so-called Wittgensteinian approach, noting soul's linguistic significance. He analyzes expressions which use the concept of soul and concludes that they are qualitatively different from testable factual expressions. He notes that soul talk is about hopes and aspirations, inspiration, or feelings deeper than friendship. He assigns it meaning outside of scientific concepts. He likens expressions of soul to creative and ethical acts, …


Do We Teach Disciplines Or Do We Teach Students?—What Difference Does It Make?, Marshall W. Gregory Apr 2010

Do We Teach Disciplines Or Do We Teach Students?—What Difference Does It Make?, Marshall W. Gregory

Marshall W. Gregory

The single most difficult notion for graduate students and new professors to grasp about teaching--and, indeed, many experienced teachers never grasp this point either--is that successful teaching to undergraduates has little to do with the degree of one's mastery of disciplinary knowledge.


Capturing Genetic Variation During Ecological Restorations: An Example From Kankakee Sands In Indiana, Rebecca W. Dolan, Deborah L. Marr, Andrew Schnabel Apr 2010

Capturing Genetic Variation During Ecological Restorations: An Example From Kankakee Sands In Indiana, Rebecca W. Dolan, Deborah L. Marr, Andrew Schnabel

Rebecca W. Dolan

Genetic variation in populations, both natural and restored, is usually considered crucial for response to short term environmental stresses and for long term evolutionary change. To have the best chance of successful long-term survival, restored populations should reflect the extant variation found in remnants, but restored sites may suffer from genetic bottlenecks as a result of founder effects. Kankakee Sands is a large-scale restoration being conducted by The Nature Conservancy (TNC) in northwestern Indiana. Our goal was to test for loss of genetic variation in restored plant populations by comparing them with TNC’s seed source nursery and with local remnant …

Sex Steroid Metabolism Polymorphisms And Mammographic Density In Pre- And Early Perimenopausal Women, Carolyn J. Crandall, Mary E. Sehl, Sybil L. Crawford, Ellen B. Gold, Laurel A. Habel, Lesley M. Butler, Mary Fran R. Sowers, Gail A. Greendale, Janet S. Sinsheimer Apr 2010

Sex Steroid Metabolism Polymorphisms And Mammographic Density In Pre- And Early Perimenopausal Women, Carolyn J. Crandall, Mary E. Sehl, Sybil L. Crawford, Ellen B. Gold, Laurel A. Habel, Lesley M. Butler, Mary Fran R. Sowers, Gail A. Greendale, Janet S. Sinsheimer

Sybil L. Crawford

INTRODUCTION : We examined the association between mammographic density and single-nucleotide polymorphisms (SNPs) in genes encoding CYP1A1, CYP1B1, aromatase, 17beta-HSD, ESR1, and ESR2 in pre- and early perimenopausal white, African-American, Chinese, and Japanese women. METHODS : The Study of Women's Health Across the Nation is a longitudinal community-based cohort study. We analyzed data from 451 pre- and early perimenopausal participants of the ancillary SWAN Mammographic Density study for whom we had complete information regarding mammographic density, genotypes, and covariates. With multivariate linear regression, we examined the relation between percentage mammographic breast density (outcome) and each SNP (primary predictor), adjusting for …

CONTEXT: Reproductive hormones are incompletely characterized during the menopause transition (MT). Hypothesis: Increased anovulation and decreased progesterone accompany progress through the MT. DESIGN: The Daily Hormone Study (DHS) of the Study of Women's Health Across the Nation (SWAN) included 848 women aged 43-53 yr at baseline who collected daily urine for one cycle or up to 50 d annually for 3 yr. MAIN OUTCOME MEASURES: LH, FSH, estrone conjugates, and pregnanediol glucuronide levels were assessed. Cycles were classified by presumed luteal (ovulatory) status and bleeding. Hormones were related to time in study, age, menopausal status, and selected variables. RESULTS: Ovulatory-appearing …


Comparative Genetics Of Seven Plants Endemic To Florida’S Lake Wales Ridge, Eric S. Menges, Rebecca W. Dolan, Rebecca Yahr, Doria R. Gordan Apr 2010

Comparative Genetics Of Seven Plants Endemic To Florida’S Lake Wales Ridge, Eric S. Menges, Rebecca W. Dolan, Rebecca Yahr, Doria R. Gordan

Rebecca W. Dolan

Here we submit that mathematical tools used in population viability analysis can be used in conjunction with floristic and faunistic surveys to predict changes in biogeographic range. We illustrate our point by summarizing the results of a demographic study of Lobelia boykinii. In this study we used deterministic and stochastic matrix models to estimate the growth rate and to predict the time to extinction for three populations growing in the Carolina bays. The stochastic model better discriminated among the fates of the three populations. It predicted extinction for two populations in the next 25 years but no extinction of the …


Was Jesus Illegitimate? The Evidence Of His Social Interactions, James F. Mcgrath Apr 2010

Was Jesus Illegitimate? The Evidence Of His Social Interactions, James F. Mcgrath

James F. McGrath

This article examines the social status of the historical Jesus in relation to recent studies that place Jesus into the social category of an illegitimate child. After surveying the evidence with respect to the situation of such individuals in first century Mediterranean and Jewish society, we shall proceed to examine whether Jesus' implied social status (as evidenced by accounts of his adult social interactions) coheres with what one would expect in the case of someone who bore the stigma of that status. Our study suggests that the scandal caused by Jesus' association with the marginalized clearly implies that he did …

The Clute Holotypes And The Herbarium Of Willard Nelson Clute In The Friesner Herbarium Of Butler University, Rebecca W. Dolan Apr 2010

The Clute Holotypes And The Herbarium Of Willard Nelson Clute In The Friesner Herbarium Of Butler University, Rebecca W. Dolan

Rebecca W. Dolan

The herbarium of Willard Nelson Clute is housed in the Friesner Herbarium (BUT). Clute, co-founder of the American Fern Society, was a staff member at Butler University in the 1920's and 30's. His collection of ferns and fern allies from the tum of the century is significant for its selected regional coverage and for type specimens of taxa described by Clute and other fern specialists of the day.


Rethinking Mechanistic Explanation, Stuart Glennan Apr 2010

Rethinking Mechanistic Explanation, Stuart Glennan

Stuart Glennan

Philosophers of science typically associate the causal-mechanical view of scientific explanation with the work of Railton and Salmon. In this paper I shall argue that the defects of this view arise from an inadequate analysis of the concept of mechanism. I contrast Salmon's account of mechanisms in terms of the causal nexus with my own account of mechanisms, in which mechanisms are viewed as complex systems. After describing these two concepts of mechanism, I show how the complex-systems approach avoids certain objections to Salmon's account of causal-mechanical explanation. I conclude by discussing how mechanistic explanations can provide understanding by unification.


Genetic Variation In Past And Current Landscapes: Conservation Implications Based On Six Endemic Florida Scrub Plants, Eric S. Menges, Rebecca W. Dolan, Robert Pickert, Rebecca Yahr, Doria R. Gordon Mar 2010

Genetic Variation In Past And Current Landscapes: Conservation Implications Based On Six Endemic Florida Scrub Plants, Eric S. Menges, Rebecca W. Dolan, Robert Pickert, Rebecca Yahr, Doria R. Gordon

Rebecca W. Dolan

If genetic variation is often positively correlated with population sizes and the presence of nearby populations and suitable habitats, landscape proxies could inform conservation decisions without genetic analyses. For six Florida scrub endemic plants (Dicerandra frutescens, Eryngium cuneifolium, Hypericum cumulicola, Liatris ohlingerae, Nolina brittoniana, and Warea carteri), we relate two measures of genetic variation, expected heterozygosity and alleles per polymorphic locus (APL), to population size and landscape variables. Presettlement areas were estimated based on soil preferences and GIS soils maps. Four species showed no genetic patterns related to population or landscape factors. The other two species showed significant but inconsistent …


Why I Am A Buddhist, Stephen Asma Feb 2010

Why I Am A Buddhist, Stephen Asma

Stephen T Asma

Profound and amusing, this book provides a viable approach to answering the perennial questions: Who am I? Why am I here? How can I live a meaningful life? For Asma, the answers are to be found in Buddhism.

There have been a lot of books that have made the case for Buddhism. What makes this book fresh and exciting is Asma's iconoclasm, irreverence, and hardheaded approach to the subject. He is distressed that much of what passes for Buddhism is really little more than "New Age mush." He loudly asserts that it is time to "take the California out of …

The great composer Ludwig van Beethoven was not only an exceptional musician but also a man of great ideals who expressed social justice in his music


Green Guilt, Stephen Asma Jan 2010

Green Guilt, Stephen Asma

Stephen T Asma

The essay discusses the more neurotic aspects of environmentalism, involving guilt over failure to recycle or turn off the lights. It notes that those most prone to these sensibilities are those who have left traditional religion. It quotes philosopher Friedrich Nietzsche who states that religious emotions such as guilt and indignation are still present in a post-Christian world. The essay argues that we should certainly save the planet but avoid the neurosis that often accompanies it.


Bees In America: How The Honey Bee Shaped A Nation, Tammy Horn Dec 2009

Bees In America: How The Honey Bee Shaped A Nation, Tammy Horn

Tammy Horn

" Honey bees--and the qualities associated with them--have quietly influenced American values for four centuries. During every major period in the country's history, bees and beekeepers have represented order and stability in a country without a national religion, political party, or language. Bees in America is an enlightening cultural history of bees and beekeeping in the United States. Tammy Horn, herself a beekeeper, offers a varied social and technological history from the colonial period, when the British first introduced bees to the New World, to the present, when bees are being used by the American military to detect bombs. Early …


Darwinian Controversies: An Historiographical Recounting, David Depew Dec 2009

Darwinian Controversies: An Historiographical Recounting, David Depew

David J Depew

This essay reviews key controversies in the history of the Darwinian research tradition: the Wilberforce-Huxley debate in 1860, early twentieth-century debates about the heritability of acquired characteristics and the consistency of Mendelian genetics with natural selection; the 1925 Scopes trial about teaching evolution; tensions about race, culture, and eugenics at the 1959 centenary celebration Darwin’s Origin of Species; adaptationism and its critics in the Sociobiology debate of 1970s and, more recently, Evolutionary Psychology; and current disputes about Intelligent Design. These controversies, I argue, are etched into public memory because they occur at the emotionally charged boundaries between public-political, technical-scientific, and …

A Brief History Of The American Fish Culture Company 1877-1997., Michael A. Rice Dec 2009

A Brief History Of The American Fish Culture Company 1877-1997., Michael A. Rice

Michael A Rice

The American Fish Culture Company operated for nearly 120 years from 1877-1997 in Carolina, Rhode Island growing three species of trout under the under the direction of several generations of the Hazard family of Peace Dale, Rhode Island. The company was one of the first trout producers in the United States, and was considered the largest fish farm in the country by the early 1920s. Major innovations of the company included early adoption of pelleted feeds, and the introduction of photoperiod manipulation to spawn fish out of season. The company ultimately failed due to intense competition from larger producers in …


Reason And Desire: The Case Of Affective Desires, Attila Tanyi Dec 2009

Reason And Desire: The Case Of Affective Desires, Attila Tanyi

Attila Tanyi

The paper begins with an objection to the Desire-Based Reasons Model. The argument from reason-based desires holds that since desires are based on reasons (first premise), which they transmit but to which they cannot add (second premise), they cannot themselves provide reasons for action. In the paper I investigate an attack that has recently been launched against the first premise of this argument by Ruth Chang. Chang invokes a counterexample: affective desires. The aim of the paper is to see if there is a way to accommodate the counterexample to the first premise. I investigate three strategies. I first deal …


Mining And Civilization, An Illustrated History, Fathi Habashi Dec 2009

Mining And Civilization, An Illustrated History, Fathi Habashi

Fathi Habashi

Mining and Civilization has been conceived to compliment the author's two books History of Metallurgy and Readings in Historical Metallurgy and to fill a gap in the literature. It is difficult to study the history of metallurgy without studying the history of mining at the same time. Each time the author visits ancient ruins or examines an ancient stone statue he recalls the work of miners who brought the material from a quarry so that the sculptor can create a work of art. History of mining, quarrying, and stone carving is history of civilization.
