Paradigm Shifts And New Worldviews: Kuhn, Laudan And Discovery In Molecular Biology, Priya Venkatesan Oct 2004

Paradigm Shifts And New Worldviews: Kuhn, Laudan And Discovery In Molecular Biology, Priya Venkatesan

Reconstruction: Studies in Contemporary Culture

[Editors' Introduction]

The author poses an alternate set of ideas concerning paradigms, normal science, research traditions and scientific revolution on the basis of the unique and inherently distinctive development of molecular biology and genetics; for, a new set of conceptual tools concerning scientific progress are required for an adequate understanding of how biological processes were elucidated under the scientific auspices of the central dogma of the genetic code. This essay concentrates on a limited study of three aspects in genetics: the study of chromosome structure, dynamics and function, reverse transcriptases, and the discovery of RNA catalysts. In attempting to analyze …

Applied Ethics In Animal Research: Philosophy, Regulation, And Laboratory Applications, John P. Gluck, Tony Dipasquale, F. Barbara Orlans Jan 2002

Applied Ethics In Animal Research: Philosophy, Regulation, And Laboratory Applications, John P. Gluck, Tony Dipasquale, F. Barbara Orlans

Purdue University Press Books

This volume is a collection of chapters all contributed by individuals who have presented their ideas at conferences and who take moderate stands with the use of animals in research. Specifically the chapters bear of the issues of: notions of the moral standings of animals, history of the methods of argumentation, knowledge of the animal mind, nature and value of regulatory structures, how respect for animals can be converted from theory to action in the laboratory. The chapters have been tempered by open discussion with individuals with different opinions and not audiences of true believers. It is the hope of …


Pkcα Translocation And Actin Remodeling In Contracting A7r5 Smooth Muscle Cells, Chenwei Li Jan 2002

Pkcα Translocation And Actin Remodeling In Contracting A7r5 Smooth Muscle Cells, Chenwei Li

Theses, Dissertations and Capstones

Recent research indicates that protein kinase C (PKC) plays an important role in smooth muscle contraction. Because PKC activation and specificity of substrate phosphorylation is believed to be associated with the relocalization of the enzyme to specific cell sites, we first investigated the subcellular translocation of PKCα in A7r5 smooth muscle cells by confocal microscopy through use of standard immunohistologic staining and PKCα - enhanced green fluorescent protein (PKCα -EGFP) fusion protein expression. PKCα was diffusely distributed throughout the cytosol in the unstimulated A7r5 cell. Upon stimulation with phorbol 12, 13 dibutyrate (PDBu), PKCα was translocated primarily to either the …


Rethinking Mechanistic Explanation, Stuart Glennan Jan 2002

Rethinking Mechanistic Explanation, Stuart Glennan

Scholarship and Professional Work - LAS

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.

How Do We Know There Is A Population-Environment Problem?, Peter J. Taylor Mar 2000

How Do We Know There Is A Population-Environment Problem?, Peter J. Taylor

Working Papers on Science in a Changing World

Five fictional friends of the author have agreed to meet and talk, hoping that he was right when he claimed that discussion crossing the usual boundaries of their fields would enrich their different inquiries and concerns. Ecolo, a natural and human ecologist, breaks the ice. He wants to marshall scientific knowledge to persuade others of the seriousness of the population problem. He is questioned by Philoso, whose philosophical bent leads her to observe the models that people use and to ask how they support the claims they make. In turn, the other three join in: Activo, an activist who is …

Interview: Brenda Laurel, Jason Challas Jul 1995

Interview: Brenda Laurel, Jason Challas

SWITCH

This interview with Brenda Laurel, Virtual Reality (VR) author and thinker, discusses the applications and challenges of VR. Creating an emphatic experience using VR technology is possible, but the challenge lies in designing an environment that models the senses to stimulate emotions. VR enables experiences of different genders, but physiological differences between the sexes exist and are important to understand. However, technology used to create the environment and simulation of physical objects in VR is only in the developmental stage. Laurel believes in the importance of keeping the mind grounded in the physical body, in order to strengthen the appreciation …

Effects Of Soluble Calcium-To-Protein Ratio On Age Gelation Of Ultra, Je Hong Ryue May 1994

Effects Of Soluble Calcium-To-Protein Ratio On Age Gelation Of Ultra, Je Hong Ryue

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reverse osmosis (RO) and ultrafiltration (UF) retentates were ultra-high temperature (UHT) processed and compared for storage life at room temperature. Viscosity studies indicated that UHT-treated, RO retentate delayed age gelation longer than UF retentate at the same total solids level (26% TS). When compared at 6.4% protein level (2x RO vs 2.7x UF where x=ratio of the feed volume to concentrate volume), the storage life for both RO and UF retentates was about 6 to 8 months.

Sodium hexametaphosphate (SHMP) and disodium phosphate (DSP) at 1, 3, 5, 10, and 20 mM concentrations were incorporated prior to UHT processing …


The Effects Of Temperature And Daylength On The Rosa Polyphenism In The Buckeye Butterfly, Precis Coenia (Lepidoptera: Nymphalidae), Kelly C. Smith Dec 1993

The Effects Of Temperature And Daylength On The Rosa Polyphenism In The Buckeye Butterfly, Precis Coenia (Lepidoptera: Nymphalidae), Kelly C. Smith

Publications

In North Carolina, Precis coenia that emerge during the Summer months exhibit a ventral hindwing (VHW) with well-defined reddish-brown and brown pattern elements on a light tan background. During late Summer and early Fall, however, individuals begin to appear with poorly defined or obscured pattern elements on a dark reddish-brown background. The present study shows that the Fall (rosa) color morph can be induced by either low rearing temperatures or short daylengths. The effect of such conditions seems to be cumulative throughout the larval life, although animals are much more sensitive during the last 24 hours of larval …

Apparent Interactions In Community Models: A Challenge For Theoretical Ecology, Peter J. Taylor Aug 1985

Apparent Interactions In Community Models: A Challenge For Theoretical Ecology, Peter J. Taylor

Working Papers on Science in a Changing World

The primary aim of this working paper is to challenge theoretical ecologists to clarify the intended status of any simple model that they use. If we restrict our attention to a subcommunity and treat it as if it were the full community, we need to invoke apparent interactions that incorporate the effects of unspecified or hidden variables as well as direct interactions. This position resembles that of previous discussions of apparent competition (Holt 1977), indirect effects (Lawlor 1979), and ecological abstraction (Schaffer 1981), but my definition of apparent interactions differs from those stated or implied by these authors. I advance …


The Relationship Between Mathematical Expression And Biological Insight: Some Issues In Community Ecology Modeling, Exemplified By The Logistic Equation, Peter J. Taylor Aug 1985

The Relationship Between Mathematical Expression And Biological Insight: Some Issues In Community Ecology Modeling, Exemplified By The Logistic Equation, Peter J. Taylor

Working Papers on Science in a Changing World

The relationship between mathematical expression and biological insight is a central problem for modelers in community ecology. In this paper I distinguish three interpretations of this relationship: models as redescriptions as observations; models as capturing fundamental or generative biological relations; and models as an aid in exploring how to formulate the inquiries we put to nature. I aim to show that we can reduce ambiguities and confusion and ecological theory if we hold the different interpretations clearly in mind. I conclude by advancing an overall strategy of model building—de/composition—in which each of the interpretations plays a role. The logistic equation, …

Problems With Kosher Slaughter, Temple Grandin Nov 1980

Problems With Kosher Slaughter, Temple Grandin

International Journal for the Study of Animal Problems

Ritual slaughter to produce kosher meat is rooted in the teachings and writings of the Talmud. However, the preslaughter handling features of modern systems, particularly the shackling and hoisting of large steers, contravene the basic message of humaneness included in the teachings. The throat-cutting of a live, conscious animal is relatively pain-free, provided that certain precautions are followed, but U.S. kosher plants need to install newly developed conveyor-restrainer systems to eliminate the abuses of shackling and hoisting. Conveyor-restrainer systems for large and small animals are discussed.

Sheep Mulesing And Animal Lib, Nancy Heneson Jul 1980

Sheep Mulesing And Animal Lib, Nancy Heneson

International Journal for the Study of Animal Problems

The practice of mulesing sheep to prevent blowfly strike has recently come under fire from the Animal Liberation movement in Australia. Although it is only one of the many issues which Animal Lib has raised in its campaign to reform various sectors of the livestock industry, it is particularly illustrative of the kinds of conflicts in world view which arise when animal rights activists turn the spotlight on the farming establishment. Spokesmen for the livestock industries are quick to stress the emotional and sometimes sensational portrayal by Animal Libbers of time-honored animal management practices, as well as the sinister role …

Definition Of The Concept Of ''Humane Treatment" In Relation To Food And Laboratory Animals, Bernard E. Rollin Jul 1980

Definition Of The Concept Of ''Humane Treatment" In Relation To Food And Laboratory Animals, Bernard E. Rollin

International Journal for the Study of Animal Problems

The very title of this talk makes a suggestion which must be forestalled, namely the idea that laboratory and food animals enjoy some exceptional moral status by virtue of the fact that we use them. In fact, it is extremely difficult to find any morally relevant grounds for distinguishing between food and laboratory animals and other animals and, far more dramatically, between animals and humans. The same conditions which require that we apply moral categories to humans rationally require that we apply them to animals as well. While it is obviously pragmatically impossible in our current sociocultural setting to expect …
