Many consumers are motivated to attend Farmers’ Markets because of the opportunity to purchase fresh and local products. The subsequent interactions at FMs provide an important pathway for the direct exchange of information. While previous research suggests that people value local food and the FM shopping experience and that purchasing directly from producers can lead to transformative learning, little is known about exactly how the shopping experience at FMs can influence consumer purchasing behavior. This study examines the extent of and (...) mechanism for such “influencing.” Using data from surveys, observations, and interviews gathered at six FMs, we analyze the interactions between consumers and vendors, including the motivations and values of both parties. We explore the question, “How do farmers’ markets facilitate change in consumer purchasing behavior?” We propose that the dynamic of change in consumer purchasing behavior at FMs takes root in the exchange of information between consumers and vendors during interactions. Our results suggest that there are three specific characteristics shared by FM consumers and vendors that lead to these meaningful interactions at FMs: symmetry of motivations to attend FMs, shared values, and mutual dependence on interactions. Then, when a consumer learns new information from a FM vendor during an interaction, the consumer is more likely to make a change in their immediate purchase. Information about the products for sale and the modes of production of those items can especially impact consumers’ immediate purchases at FMs. We found that FM interactions can also impact long-term purchasing behavior, such as purchasing more organic or locally produced foods. Our results suggest that FM interactions may have significant implications for consumer health, local economies, and the environment. (shrink)

What is right with this “comic” of Euripides's timeless and irreplaceable drama, The Trojan Women, is what was always right about a play that is relentlessly relevant. Carson's translation, spare and clear, distills the language of the original but keeps what is important, including some mouth-puckeringly wry lines. There is barbed wit and heartbreaking lullaby, sometimes coinciding on one page. Thus, the chorus comments, “Troy, you made a bad deal: / ten thousand men for a single coracle of cunt (...) appeal.” In the middle of the same page, the Greek herald Talthybius addresses Hector and Andromache's infant son Astyanax, whom he has come to carry off so that the baby can be thrown from the battlements: “Come along, little mushroom, / little rootlet, little sip, little milk fly, little asterisk, little welkin, / little silhouette, little sugar bubble—/ let go of your mother. / She's broken.” Then lower down on the same page: “It's time for your infinite leap / as decreed by the vote of men. / Take him. / The man to transact things like this / is one who doesn't know pity.”What is wrong with this new rendering is Bruno's awkward, amateurish drawings. Yes, the chorus are all animals, as are all the main characters except mad Cassandra (a partial exception might be made for Menelaus, who is some kind of machine); but Bruno is no Art Spiegelman, and this is no Maus. Spiegelman's cats, pigs, and mice make perfect sense and are elegantly and clearly depicted; they add resonance to the story without raising further questions. In this Trojan Women, it makes sense that Hecuba is an old bitch or Helen a svelte fox in high heels. Poseidon, a wave: okay. But Talthybius, a colossal raven? Athena, “a big pair of overalls, carrying an owl mask in one hand”? Andromache, “a poplar tree with trunk split and roots dragging out the back of the cart”? The infant Astyanax whom Andromache cradles in one Ent-like arm looks more like a cocoon or a hornet's nest or a hypertrophied oak gall than anything else. Menelaus, when he arrives, is “some sort of gear box, clutch or coupling mechanism, once sleek, not this year's model.” These surreal leaps might well work on the stage or screen, but the need to explain them in the text shows how uncomfortably they fit into the story. Carson's explanations, of course, constitute her only significant departures from Euripides.We do not need Bruno's drawings; Carson's pared-down text might work quite well on its own. But even grant the hypothetical that these drawings are an organic and crucial part of this version's vision, then the drawings should not need to be explained. Less would be more. What this version of the classic drama gains in succinctness it loses in tonal clarity—having said which, I would still like to try it out on my students, who might help me to change my mind. Does this retelling of the story remain heartrending and cruel, suffused with irony, sharpened by flashes of wit? Yes. Was it worth the experiment of turning the tragedy into a comic? Sure. Is this uneasy mix of verbal mastery and wobbly draftsmanship the ultimate version of The Trojan Women? Nope. (shrink)

Gifford Pinchot was a noted forestry expert, a conservationist, and governor of Pennsylvania. Rachel Carson, celebrated for her groundbreaking books that raised awareness of the negative human impact on the natural environment, was born, raised, and educated in Pennsylvania. Although these Pennsylvanians are both environmentalists, they approached the natural environment very differently and embody two main positions in contemporary environmental ethics. After situating their environmental legacies among contemporary environmental ethics, this paper then discusses implications of the irreconcilability of (...) their positions on environmental progress; the concept of environmental legacy; and the importance of reflecting on the lives of environmentalists like Pinchot and Carson.

Rachel Carson is well known as a founder of the modern American environmental movement, which some date to the publication of Silent Spring in 1962. This essay argues that Carson was not just a successful polemicist, but a deep and insightful environmental thinker, whose life and writings have much to offer contemporary environmental philosophy. It focuses on explicating the environmental ethics articulated in Silent Spring, which rest on the triple foundation of human health considerations, the moral considerability (...) of non-human beings, and the value to humans of preserving wild nature and a diverse and varied landscape. Carson generally emphasizes the complementarity in the great majority of cases of the three basic goals of protecting human health, preserving non-human life, and promoting human flourishing. In trying to move her society toward greater recognition of non-human interests and higher human interests, she develops an environmental ethics with both non-anthropocentric and enlightened anthropocentric elements. While Silent Spring shows how these two aspects may ‘converge’ regarding an important public policy issue, Carson’s own life, dedicated to knowing and appreciating nature, shows how they converge at the personal level. Three further themes round out the ethical argument of Silent Spring. First, Carson’s disapproval of economism – the overvaluation or exclusive focus on economic goals and pursuits. Second, her criticisms of a human ‘war on nature’. Third, her warnings concerning the increased artificiality and simplification of the landscape. (shrink)

In contrast to "the land ethic," Rachel Carson's Under the Sea-Wind suggests a trans-ecotonal sea ethic, which understands human's perception as inhibited by ecotones, such as shorelines and the ocean surface, and suggests four foundational concepts: 1.) Humans are not fully adapted to life in the oceans. 2.) Humans need to understand the scale and complexity of ocean ecosystems. 3.) Humans disrupt ocean ecosystems by over-harvesting their productivity, and modifying ecosystem processes and linkages, such as migrations. 4.) Human (...) imagination and rational scientific investigation can traverse the ecotones, allowing us to more fully value ocean life and processes. (shrink)

This essay argues for reading Rachel Carson’s Silent Spring as a work of love that calls for an environmental politics of desire rather than self-preservation narrowly construed. I make this argument by reading Silent Spring in conjunction with the extant love letters of Carson and Dorothy Freeman, where they depict their love as a wondrous multispecies achievement constituted through encounters with birds. I argue that their example reveals that love need be neither worldless nor heteronormative, but may (...) be a world-disclosing practice that leads individuals to live, and desire to live, differently. Reading Silent Spring through the lens of these letters, I argue that it calls us to see the threat insecticides pose not only to “mere life” but also to pleasurable lives of wonder and love. I build on Silent Spring to argue for an alternative politics of survival in the face of climate change: one that foregrounds the connections between inter-human affects and a vibrant multispecies world, between intimate and public feelings, and calls for preservation of a multispecies world through and on behalf of human pleasure.

The biological sciences have become increasingly reliant on so-called 'model organisms'. I argue that in this domain, the concept of a descriptive model is essential for understanding scientific practice. Using a case study, I show how such a model was formulated in a preexplanatory context for subsequent use as a prototype from which explanations ultimately may be generated both within the immediate domain of the original model and in additional, related domains. To develop this concept of a descriptive model, I (...) focus on use of the nematode worm Caenorhabditis elegans and the wiring diagrams that were developed as models of its neural structure. In addition, implications of the concept of a descriptive model, particularly its relevance for the data-phenomena distinction as well as its relation to long-standing debates on realism, are briefly examined.

Although cases are central to the epistemic practices utilized within clinical medicine, they appear to be limited in their ability to provide evidence about causal relations because they provide detailed accounts of particular patients without explicit filtering of those attributes most likely to be relevant for explaining the phenomena observed. This paper uses a series of recent case reports to explore the role of cases in casual attribution in medical diagnosis. It is argued that cases are brought together by practitioners (...) to generate causal attributions and testable predictions using a manipulability view of causation. (shrink)

ArgumentWe examine the criteria used to validate the use of nonhuman organisms in North-American alcohol addiction research from the 1950s to the present day. We argue that this field, where the similarities between behaviors in humans and non-humans are particularly difficult to assess, has addressed questions of model validity by transforming the situatedness of non-human organisms into an experimental tool. We demonstrate that model validity does not hinge on the standardization of one type of organism in isolation, as often the (...) case with genetic model organisms. Rather, organisms are viewed as necessarily situated: they cannot be understood as a model for human behavior in isolation from their environmental conditions. Hence the environment itself is standardized as part of the modeling process; and model validity is assessed with reference to the environmental conditions under which organisms are studied.

This paper aims to identify the key characteristics of model organisms that make them a specific type of model within the contemporary life sciences: in particular, we argue that the term “model organism” does not apply to all organisms used for the purposes of experimental research. We explore the differences between experimental and model organisms in terms of their material and epistemic features, and argue that it is essential to distinguish between their representational scope and representational target. We also examine (...) the characteristics of the communities who use these two types of models, including their research goals, disciplinary affiliations, and preferred practices to show how these have contributed to the conceptualization of a model organism. We conclude that model organisms are a specific subgroup of organisms that have been standardized to fit an integrative and comparative mode of research, and that it must be clearly distinguished from the broader class of experimental organisms. In addition, we argue that model organisms are the key components of a unique and distinctively biological way of doing research using models.Keywords: Experimental organism; Genetics; Model organism; Modeling; Philosophy of biology; Representation.

This article unpacks a particular use of ‘cases’ within developmental biology, namely as a means of describing the typical or canonical patterns of phenomena. The article explores how certain cases have come to be established within the field and argues that although they were initially selected for reasons of convenience or ease of experimental manipulation, these cases come to serve as key reference points within the field because of the epistemological structures imposed on them by the scientists using them and, (...) hence, become usable in a wider variety of circumstances including future theory development.

Objective: Even when critically ill patients are almost certain to die from their illnesses, there is generally an element of prognostic uncertainty. Little is known about how physicians handle this uncertainty in conversations with surrogate decision makers. We sought to evaluate whether and how physicians discuss prognostic uncertainty with surrogate decision makers of patients who are highly likely, but not certain, to die. Design: We audiotaped and transcribed discussions between clinicians and surrogate decision makers at two major California teaching hospitals (...) from 2006 through 2008. Physicians completed a questionnaire addressing their prognostic estimates for patients' survival to hospital discharge. Participants: We included physicians and surrogates of 12 incapacitated, critically ill patients. Measurements: We analyzed transcripts of discussions in which physicians' estimates of patients' chances of hospital survival were 1% to 5%; we coded whether physicians disclosed the prognostic uncertainty and, if so, how they conveyed that death was highly likely but not certain. Results: Physicians' estimates of short-term survival were 1% to 5% for 12 of the 70 patients enrolled in the original study. In 8 of 12 cases, physicians conveyed prognostic uncertainty by using probabilistic language or by an explicit mention of uncertainty. In four cases, physicians made at least one statement that either implied or was ambiguous about whether death was certain. Conclusion: We observed variability in how physicians handle prognostic uncertainty in their discussions with surrogates of patients who are highly likely, but not certain, to die, including some circumstances in which physicians stated or implied that death was certain.

Bioethics has entered a new era: as many commentators have noted, the familiar mantra of autonomy, beneficence, nonmaleficence, and justice has proven to be an overly simplistic framework for understanding problems that arise in modern medicine, particularly at the intersection of public policy and individual preferences. A tradition of liberal pluralism grounds respect for individual preferences and affirmation of competing conceptions of the good. But we struggle to maintain (or at times explicitly reject) this tradition in the face of individual (...) preferences that we find distasteful, suspect, or even repugnant, especially where the broader social good or respect for equality is at stake. Directed donation presents us with such a dilemma: can we uphold the right of self-determination through respect of individual preferences regarding disposition of transplantable organs while at the same time maintaining an allocation system that reflects values of equity and justice claimed to underlie the socially negotiated practice of transplantation? Or are some preferences simply to be deemed unethical and not respected, even if that leads to a reduction in the number of transplantable organs available and to an apparent disregard for the autonomous decisions of the recently deceased?

Through an examination of the actual research strategies and assumptions underlying the Human Genome Project (HGP), it is argued that the epistemic basis of the initial model organism programs is not best understood as reasoning via causal analog models (CAMs). In order to answer a series of questions about what is being modeled and what claims about the models are warranted, a descriptive epistemological method is employed that uses historical techniques to develop detailed accounts which, in turn, help to reveal (...) forms of reasoning that are explicit, or more often implicit, in the practice of a particular field of scientific study. It is suggested that a more valid characterization of the reasoning structure at work here is a form of case-based reasoning.

I argue for an environmental virtue ethics which specifies human excellence and flourishing in relation to nature. I consider Henry David Thoreau, Aldo Leopold, and Rachel Carson as environmental virtue ethicists, and show that these writers share certain ethical positions that any environmental virtue ethics worthy of the name must embrace. These positions include putting economic life in its proper,subordinate place within human life as a whole; cultivating scientific knowledge, while appreciating its limits; extending moral considerability to the (...) nonhuman world; and supporting wilderness protection. I argue that Thoreau, Leopold, and Carson themselves exemplify the potential for cultivating excellence in engagement with wild nature: their lives are among our most powerful arguments for its preservation.

The so-called "biometric-Mendelian controversy" has received much attention from science studies scholars. This paper focuses on one scientist involved in this debate, Arthur Dukinfield Darbishire, who performed a series of hybridization experiments with mice beginning in 1901. Previous historical work on Darbishire's experiments and his later attempt to reconcile Mendelian and biometric views describe Darbishire as eventually being "converted" to Mendelism. I provide a new analysis of this episode in the context of Darbishire's experimental results, his underlying epistemology, and his (...) influence on the broader debate surrounding the rediscovery and acceptance of Mendelism. I investigate various historiographical issues raised by this episode in order to reflect on the idea of "conversion" to a scientific theory. Darbishire was an influential figure who resisted strong forces compelling him to convert prematurely due to his requirements that the new theory account for particularly important anomalous facts and answer the most pressing questions in the field.

The majority of midwives in the UK are employed within the NHS. They are legally bound to fulfil their contractual obligations to their employers. At the same time they are professionally mandated to interpret and act on the UKCC's Code of professional conduct. Midwives have always maintained that they are autonomous practitioners, and the Code is written in a way that endorses this belief. Underlying the Code is the assumption that midwives have moral and professional freedom to act on its (...) imperatives. However, midwives' claim to autonomy is flawed, and therefore the Code's claim to be a source of empowerment is also flawed. Underlying the difficulties is a conflict derived from the imposition of a deontologically-based professional Code on to a workforce that is constrained within and employed by the utilitarian-based NHS.

The past year in bioethics in Australia has been relatively predictable. We continue to struggle with rising healthcare costs, though thankfully not on par with numerous other countries due to a relatively positive economic outlook. We are still fighting difficulties associated with higher medical indemnity costs, which have again caused many physicians to leave private practice, particularly in high-risk and specialty practice areas. In response, the federal government delayed the imposition of the medical indemnity levy for physicians until mid 2005. (...) In May, the Australian Law Reform Commission and the Australian Health Ethics Commission issued their final joint report on genetic testing entitled “Essentially Yours” and endorsed use of genetic tests by insurance companies, despite the concerns of some geneticists and many members of the public about their scientific reliability. However, they also advocated the establishment of the Human Genetics Commission of Australia to oversee such uses of genetic tests in terms of both scientific and actuarial reliability, and debates continue over the implementation of this and a number of their other recommendations. And state governments continue to phase in smoking bans in public places, with most implementing full bans in enclosed restaurants and cafes and planning to require provision of nonsmoking areas in all pubs within the next year. a.

Community databases have become crucial to the collection, ordering and retrieval of data gathered on model organisms, as well as to the ways in which these data are interpreted and used across a range of research contexts. This paper analyses the impact of community databases on research practices in model organism biology by focusing on the history and current use of four community databases: FlyBase, Mouse Genome Informatics, WormBase and The Arabidopsis Information Resource. We discuss the standards used by the (...) curators of these databases for what counts as reliable evidence, acceptable terminology, appropriate experimental set-ups and adequate materials (e.g., specimens). On the one hand, these choices are informed by the collaborative research ethos characterising most model organism communities. On the other hand, the deployment of these standards in databases reinforces this ethos and gives it concrete and precise instantiations by shaping the skills, practices, values and background knowledge required of the database users. We conclude that the increasing reliance on community databases as vehicles to circulate data is having a major impact on how researchers conduct and communicate their research, which affects how they understand the biology of model organisms and its relation to the biology of other species.
