Many philosophers of biology have embraced a version of pluralism in response to the failure of theory reduction but overlook how concepts, methods, and explanatory resources are in fact coordinated, such as in interdisciplinary research where the aim is to integrate different strands into an articulated whole. This is observable for the origin of evolutionary novelty—a complex problem that requires a synthesis of intellectual resources from different fields to arrive at robust answers to multiple allied questions. It is an apt (...) locus for exploring new dimensions of explanatory integration because it necessitates coordination among historical and experimental disciplines . These coordination issues are widespread for the origin of novel morphologies observed in the Cambrian Explosion. Despite an explicit commitment to an integrated, interdisciplinary explanation, some potential disciplinary contributors are excluded. Notable among these exclusions is the physics of ontogeny. We argue that two different dimensions of integration—data and standards—have been insufficiently distinguished. This distinction accounts for why physics-based explanatory contributions to the origin of novelty have been resisted: they do not integrate certain types of data and differ in how they conceptualize the standard of uniformitarianism in historical, causal explanations. Our analysis of these different dimensions of integration contributes to the development of more adequate and integrated explanatory frameworks. (shrink)

Disability humor raises a hidden paradox that makes people feel uncomfortable. What is so funny about having a disability when others think that it is a tragedy? This article analyzes the social creation, context, purposes and consequences of disability humor. Disability humor is seen to be anchored simultaneously in tragedy and comedy so that both literary vehicles give meaning to the disability experience.

This book explores the effects of technology on the education of digital generations and the technology-mediated interaction that will prepare these generations for an unpredictable future. It discusses strategies and approaches for curriculum design, professional development, and other aspects of school organization involving technology.

Bovine growth hormone is a protein that occurs naturally in cattle. A chain of 190 amino acids, bGH is produced by the pituitary gland and helps to regulate a cow’s lactational cycle; generally speaking and up to a certain point, the more bGH a cow has, the more milk she gives. Using the techniques of genetic engineering, researchers at Monsanto Company have isolated the gene that produces the protein and devised low-cost techniques to manufacture it. Bacteria are placed into fermentation (...) chambers where they multiply rapidly; lab technicians then extract and purify the final product, which is identical to the naturally occurring protein in 189 of the 190 amino acids; and the product is then injected into cows.

Agricultural biotechnology refers to a diverse set of industrial techniques used to produce genetically modified foods. Genetically modified (GM) foods are foods manipulated at the molecular level to enhance their value to farmers and consumers. This book is a collection of essays on the ethical dimensions of ag biotech. The essays were written over a dozen years, beginning in 1988. When I began to reflect on the subject, ag biotech was an exotic, untested, technology. Today, in the first year of (...) the millenium, the vast majority of consumers in the United States have taken a bite of the apple. Milk produced by cows injected with a GM protein called recombinant bovine growth hormone (bGH), is found, unlabelled, on grocery shelves throughout the US. In 1999, half of the soybeans and cotton harvested in the US were GM varieties. Billions of dollars of public and private monies are being invested annually in biotech research, and commercial sales now reach into the tens of billions of dollars each year. Whereas ag biotech once promised to change American agriculture, it now is in the process of doing so. (shrink)

Three correctives can get researchers out of the trap of constructing unitary theories of “thinking”: (1) Strong inference methods largely avoid problems associated with universal prescriptive normativism; (2) theories must recognize that significant modularity of cognitive processes is antithetical to general accounts of thinking; and (3) consideration of the domain-specificity of rationality render many of the present article's issues moot.

Cybersecurity research often describes people as understanding internet security in terms of metaphorical mental models (e.g., disease risk, physical security risk, or criminal behavior risk). However, little research has directly evaluated if this is an accurate or productive framework. To assess this question, two experiments asked participants to respond to a statistical reasoning task framed in one of four different contexts (cybersecurity, plus the above alternative models). Each context was also presented using either percentages or natural frequencies, and these tasks (...) were followed by a behavioral likelihood rating. As in previous research, consistent use of natural frequencies promoted correct Bayesian reasoning. There was little indication, however, that any of the alternative mental models generated consistently better understanding or reasoning over the actual cybersecurity context. There was some evidence that different models had some effects on patterns of responses, including the behavioral likelihood ratings, but these effects were small, as compared to the effect of the numerical format manipulation. This points to a need to improve the content of actual internet security warnings, rather than working to change the models users have of warnings. (shrink)

When Francis Bacon declared his intent to torment and interfere with nature, he probably did not envision sickly experimental hogs with human genes. But the Baconian desire to understand nature and place “her” at our command has entrenched itself in our collective psyche, and the bioengineering epoch has enabled us to impose our desires in ways Bacon could not have imagined. In so doing, have we stepped over the bounds of decency?

Environmental ethics consists of a set of competing theories about whether human actions and attitudes to nature are morally right or wrong. Ecocentrists are holists whose theory locates the primary site of value in biological communities or ecosystems and who tend to regard actions interfering with the progress of an ecosystem toward its mature equilibrium state as prima facie wrong. I suggest that this form of ecocentrism may be built on a questionable scientific foundation, organismic ecology, and that a better (...) scientific foundation for environmental ethics may be found in individualistic neo-Darwinian population biology. However, the latter approach probably requires a corresponding shift away from ethical holism and toward approaches locating value primarily in individuals. I call such environmental ethicists ‘extensionists’ and briefly outline an extensionist environmental ethic. (shrink)

I pulled weeds out of half-mile rows of soybeans on grandma and grandpa’s farm long before I heard of the controversy surrounding herbicide resistance and genetic engineering. Twenty years ago, Gordie, Richard, Greg, and I “walked beans,” not knowing that our fists and scythes were not the only means available to Grandpa for killing weeds. We knew little then about uprooting thistles with tractors and discs or about spraying chemicals onto mustard. We knew only that a cool thermos of lemonade (...) and some stem looks from Mom would motivate our troop into action because every good Iowan hated volunteer corn and sunflower shoots. The hatred stemmed as much from the fact that the weeds made a field “look messy from the highway” as from the fact that they cut down yields; Grandma had aesthetic sensibilities as highly developed as any character in Greg Brown’s song.

When I wrote “The Case Against bGH” in the late 1980s, I enjoyed eating meat, enjoyed serving it to my family, and believed one could simultaneously defend traditional family farms and the welfare of animals. Shortly after finishing that article, I read again, and more carefully, Tom Regan’s The Case for Animal Rights. 2 Regan’s arguments challenged my presuppositions.

When social issues involve questions as momentous as global survival, ethicists should do more than analyze arguments and formulate principles. They should help us find stories to put our values into practice. In the essays collected here, I have tried to tell my story in the hope that others might find it instructive.

I worked for many years constructing my version of the global case but, as I continued to try to strengthen it, I slowly began to lose confidence. My unease began with several personal experiences. One of our children had a common but annoying physical ailment, for which our pediatrician prescribed a very expensive nasal spray. When I inquired about its cost, the pharmacist informed me that it was a new, genetically engineered, product. The spray worked, and Karen and I never (...) batted an eye. (shrink)

Thus the extrinsic argument against ag biotech. In considering whether it is a good argument, I believe we should simply assume that is true. Substantially risky technologies, perhaps by definition, should not be developed. Seeing no reason to contest, therefore, I will focus on.

Einstein's General Theory of Relativity links the metrical structure of the cosmic order (or "cosmology") to the contingent distributions of matter and energy throughout the universe, one of the chief areas of investigation in astrophysics. However, presently we have neither devised nor discovered system of uniform relations whereby we can make our cosmological measurements intelligible. This is "the measurement problem of cosmology." Using both historical ideas (such as A.N. Whitehead's work in the 1920s) and contemporary evidence and theories, argue that (...) the measurement problem has neither been fully understood nor rightly interpreted. With better grasp of this problem, such as am attempting to provide, the prospects for solution look brighter. (shrink)

Reasoning about social groups and their associated markers was investigated as a particular case of human reasoning about cue-category relationships. Assertions that reasoning involving cues and associated categories elicits specific probabilistic assumptions are supported by the results of three experiments. This phenomenon remains intact across the use of categorical syllogisms, conditional syllogisms, and the use of social groups that vary in their perceived cohesiveness, or entitativity. Implications are discussed for various theories of reasoning, and additional aspects of social group/coalitional reasoning (...) are also discussed. (shrink)

A more complete and balanced theoretical framework for social psychology, as recommended in the target article, must include functional explanations of processes – moving beyond enumerations of processes and their properties. These functional explanations are at a different, but complementary, level from process descriptions. The further advancement of social psychology relies on the incorporation of such multilevel explanations.

Female waist-to-hip ratio (WHR) has generally been an important general predictor of ratings of physical attractiveness and related characteristics. Individual differences in ratings do exist, however, and may be related to differences in the reproductive tactics of the male raters such as pursuit of short-term or long-term relationships and adjustments based on perceptions of one’s own quality as a mate. Forty males, categorized according to sociosexual orientation and physical qualities (WHR, Body Mass Index, and self-rated desirability), rated female models on (...) both attractiveness and likelihood they would approach them. Sociosexually restricted males were less likely to approach females rated as most attractive (with 0.68–0.72 WHR), as compared with unrestricted males. Males with lower scores in terms of physical qualities gave ratings indicating more favorable evaluations of female models with lower WHR. The results indicate that attractiveness and willingness to approach are overlapping but distinguishable constructs, both of which are influenced by variations in characteristics of the raters.

Both the theoretical frameworks that organize the first part of Barbey & Sloman's (B&S's) target article and the empirical evidence marshaled in the second part are marked by distinctions that should not exist (i.e., false dichotomies), conflations where distinctions should be made, and selective omissions of empirical results that create illusions of theoretical and empirical favor.

Special design criteria are largely unable to discriminate between claims that specific competencies in judgements under uncertainty are a result of an adaptation for representing naturally sampled frequencies, or due only to inherent properties of such a format. Because divisions between these perspectives are thin, evidence via additional criteria are persuasive only in combination, using inference to the best available explanation.

Discourse about the use of animals in biomedical research usually focuses on two issues: its empirical and moral use. The empirical issue asks whether the use of nonhumans in experiments is required in order to get data. The moral issue asks whether the use of nonhumans can be defended as matter of ethical theory. Although the use of animals in research may involve a plausible necessity claim, no moral justification exists for using nonhumans in situations in which we would not (...) use humans. (shrink)

Over the last generation, the womanist idea--and the tradition blooming around it--has emerged as an important response to separatism, domination, and oppression. Gary L. Lemons gathers a diverse group of writers to discuss their scholarly and personal experiences with the womanist spirit of women of color feminisms. Feminist and womanist-identified educators, students, performers, and poets model the powerful ways that crossing borders of race, gender, class, sexuality, and nation-state affiliation(s) expands one's existence. At the same time, they bear witness (...) to how the self-liberating theory and practice of women of color feminism changes one's life. Throughout, the essayists come together to promote an unwavering vein of activist comradeship capable of building political alliances dedicated to liberty and social justice. Contributors: M. Jacqui Alexander, Dora Arreola, Andrea Assaf, Kendra N. Bryant, Rudolph P. Byrd, Atika Chaudhary, Paul T. Corrigan, Fanni V. Green, Beverly Guy-Sheftall, Susan Hoeller, Ylce Irizarry, M.

A number of fairness issues and principles are developed and discussed from the context of personnel selection. It is noted that not too much attention has been paid to these issues and concerns in the past. A distinction is made between justice and fairness having to do with the procedural components and processes of selection, the nature of the information used to make selection decisions, and the resulting outcomes of the selection process. Ideas for future research and exploration are also (...) extended. (shrink)

In 1973, Richard Sylvan began his seminal essay, "Do We Need a New, an Environmental Ethic?" with these words: "It is increasingly said that ... Western civilization ... stands in need of a new ethic ... setting out people's relations to the natural environment." In the intervening years, it has increasingly been said that Western civilization is in need of ecocentrism, an ethic according to which a thing's value is derived from its contribution to the integrity, stability, and beauty of (...) ecosystems. Do those interested in agricultural ethics need a new, an ecocentric, ethic? I argue that the answer is no. Agriculturalists must look elsewhere for an adequate ethic setting out our relations to the natural environment. (shrink)

Discourse about the use of animals in biomedical research usually focuses on two issues. The first, which I will refer to as the “necessity issue,” is empirical and asks whether the use of nonhumans in experiments is required in order to gather statistically valid information that will contribute in a significant way to improving human health. The second, which I will refer to as the “justification issue,” is moral and asks whether the use of nonhumans in biomedical research, if necessary (...) as an empirical matter, can be defended as a matter of ethical theory.If it is not necessary as an empirical matter to use animals in research, then there is no need to inquire about moral justification. Therefore, I examine the necessity issue first. The argument that it is necessary to use nonhumans in biomedical research, though flawed, is at least plausible, unlike our necessity arguments for other animal uses. I then discuss the justification issue and conclude that we cannot morally justify using nonhuman animals in research. (shrink)

Encyclopedia entry for the British mathematician and American Philosopher Alfred North Whitehead. Usefully summarizes his life and work for non-specialists and, more especially, interested persons outside of the philosophical disciplines per se.

Donald Davidsons classic argument for the impossibility of reducing mental events to physicallistic ones is analyzed and formalized in relational logic. This makes evident the scope of Davidsons argument, and shows that he is essentially offering a negative transcendental argument, i.e., and argument to the impossibility of certain kinds of logical relations. Some final speculations are offered as to why such a move might, nevertheless, have a measure of plausibility.
