Community supported agriculture programs are transforming the way people relate to food and agriculture. Many researchers have considered the transformative potential of CSAs on economic, social, and environmental relations. They illustrate how participants are embedded in broader political economic transformations. The same focus, however, has not been given to CSAs’ transformative impact on individual shareholders—especially in terms of their relationship to food and health. We draw together literatures from behavioral economics, econometrics, and political ecology to evaluate the potential impacts of (...) CSA participation on food lifestyle behaviors. Using primary data drawn from a survey of four groups with distinct food acquisition environments, we compare respondents’ self-assessed food-related behaviors along three different categories: produce versus processed food consumption, food away from home consumption, and food acquisition and interest in nutrition. By documenting between-group differences, we confirm that shareholders display significant absolute differences to other groups along numerous indicators related to the above-stated categories and in general assessments of health. These differences correspond directionally to behaviors public health officials identify as correlated to beneficial health outcomes. We conclude by theorizing how the food environments delineated by a CSA exchange relationship provide unique reflexive opportunities for participants to develop diverse food-related skills and behaviors.

This chapter begins with a brief overview of the categories of subjective effects of alcohol, then considers the role of subjective effects from the context of prominent contemporary theories of alcohol use and misuse. Building on this conceptual foundation, it discusses important features of beverage and dose and characteristics of the setting that affect the subjective experience of drinking. It then considers what is known based on the various methodological approaches used to investigate subjective effects — including survey research on (...) alcohol expectancies and drinking motives, and ecological momentary assessment — with a particular emphasis on experimental research.

Summary Although Sir William Forbes of Pitsligo's An Account of the Life and Writings of James Beattie has long served as an invaluable resource for those interested in Beattie's life and thought, there has been little scholarship on the genesis of Forbes's book. This article considers the role played by Dugald Stewart—as well as that of his friend, Archibald Alison—in the making of Forbes's Life of Beattie. It also examines the reasons for Forbes's decision not to print Stewart's letter (...) in its entirety in the Life of Beattie and explores the letter's significance for understanding Stewart's philosophical development.

Woods et al. (2015) claim that secular Simple Reaction Time (SRT) slowing (Woodley et al. 2013), disappears once modern studies are corrected for software and hardware lag, and once Galton’s data are corrected for fastest-response selection. Here, this is challenged with a reanalysis of the secular slowing of SRT in the UK amongst large (N>500), population-representative age-matched (≊18-30 years) studies. Starting with Galton’s sample, this is assigned the simulated value estimated by Dodonova and Dodonov (2013, who like Woods (...) et al. were critical of secular SRT slowing, owing to measurement issues) on the basis that he collected the fastest of three trials (207.5ms). The two sexes in Galton’s study are combined (as in Woods et al.), raising the weighted sample mean to 208.5ms. Next is the Wilkinson and Alison (1989) study, which attempted to replicate Galton’s study one century later, collecting SRTs as part of an exhibit in the London Science Museum. An electronic chronoscope recorded SRTs on magnetic tape, and sampled over eight trials with micro-processor-determined variable foreperiods. The mean SRT value for the 1,189 participants aged between 20 and 29 is 245ms. The presence of long and variable foreperiods necessitates a penalty of 10ms (Dodonova & Dodonov, 2013). Another 10ms should be deducted based on key-pressing time (Dodonova & Dodonov, 2013), reducing the mean to 225ms. The studies of Deary and Der (2005) and Der and Deary (2006) are also included. The first utilized the highly representative Scottish Twenty-07 cohort. Dodonova and Dodonov (2013) identified a 53ms lag stemming from liquid crystal stimulus onset delay. This is subtracted from the weighted average of the two sexes (300.8ms), along with another 10ms for key-pressing time. The resultant mean is 237.8ms.Dodonova and Dodonov (2013) cleaned the male data in the Der and Deary (2006) study, collected from the representative UK Health and Lifestyle Survey, by removing cases for which SRT standard deviations exceeded those for choice RT. This reduced the N from 834 to 661, and also reduced the mean from 300ms to 284ms. The estimate was also penalized for LCD onset delay and key-pressing time, reducing the mean to 221ms. When the SRT value for the female sample is penalized equivalently the resulting value is 239ms. In order to simulate the female N for the purposes of taking a weighted average of both sexes, the actual female N is reduced in proportion to the male N (79.3%=881), yielding a weighted mean of 230.9ms for a combined sample-size of 1,472. Table 1 presents the data used in the analysis.Table 1 SRT means, sample sizes and sampling years for four large, age-matched UK samples[Table 1 here]Consistent with Dodonova and Dodonov (2013), N-weighted regression is employed, as the only data on sample variability is sample size. Figure 1 illustrating the secular trend in UK SRT over 100 years.[Figure 1 here] Figure 1. Secular SRT slowing across four large, representative studies from the UK spanning a century. Bubble-size is proportional to sample size. Combined N=6,622. The secular slowing between UK studies is statistically significant (β=0.97; 95% CI=0.969 to 0.971, N=6,622), at –22.8ms a century. Additional evidence for generational SRT slowing comes from Verhaeghen (2014), who suggested that the ratio of longitudinal to cross-sectional age-related slowing might tentatively infer generational changes in processing speed. Verhaeghen reports ratios for two SRT studies (0.91 and 1.15), implying both secular losses and gains. For the study of Deary and Der (2005), the SRT ratios are “censored because they were excessively large” (p. 256). In this study, the ratio of the cross-sectional slowing trend (taking the weighted average of all paired between-cohort differences rescaled in terms of change per decade for males and females), to the weighted average decadal longitudinal slowing trend for both the males and females is 0.73, for an N of 1,926 (cf. Woodley et al., 2014b, for a detailed reanalysis of this dataset). The weighted average of the three SRT ‘Verhaeghen ratios’ is 0.9 (N=4,078) – tentatively consistent with generational declines (i.e. a ratio of <1). In conclusion Woods et al. (2015) have undoubtedly made an important contribution to the debate concerning the role of software and hardware lag in the inflation of contemporary estimates of SRT, however the evidence for generational SRT slowing remains quite compelling.

John Woods' The Logic of Fiction, now thirty-five years old, is a ground-breaking event in the establishment of the semantics of fiction as a stand-alone research programme in the philosophies of language and logic. There is now a large literature about these matters, but Woods' book retains a striking freshness, and still serves as a convincing template of the treatment options for the field's key problems. The book now appears in a second edition with a new Foreword by (...) Nicholas Griffin and an extended bibliography covering the period 1969-2009. As Griffin notes in his Foreword, it is "surprising on looking back to discover how little was written on the semantics of fiction before John Woods' The Logic of Fiction was published in 1974. The surprise is the greater because Woods' book appeared after almost a quarter century of fierce philosophical debate about reference Fictional discourse, one would have thought, would be an important testing ground for philosophical theories of referential expressions and one, moreover, in which the standard theories would likely be tested to destruction. " " One of the great merits of Woods' book is that it takes seriously the wide-ranging demands that fiction imposes on logic and semantics, and does not try to force fiction into some pre-conceived logical mould. but thanks to Woods' pioneering efforts, we are much closer to one now than we were when he set out to write his book. His book was not the last word on the logic of fiction; it was much more important: it was nearly the first." NICHOLAS GRIFFIN is Canada Research Chair in Philosophy at McMaster University. Recent publications include Russell vs Meinong: The Legacy of "On Denoting," edited with Dale Jacquette. JOHN WOODS is Director of the Abductive Systems Group at the University of British Columbia and Charles S. Peirce Visiting Professor of Logic in the Group on Logic and Computational Science, King's College London. He has two forthcoming books on fiction - an edited volume, Fictions and Models: New Essays, and a research monograph, Sherlock's Member: New Perspectives on the Semantics of Fiction, both to appear in 2010.

Anti-realism about the foundations of logic are curiously absent from the literature. This is especially striking given natural analogies with moral anti-realis.

In all three of its manifestations, —abusive, circumstantial and tu quoque—the role of the ad hominem is to raise a doubt about the opposite party’s casemaking bona-fides.Provided that it is both presumptive and provisional, drawing such a conclusion is not a logical mistake, hence not a fallacy on the traditional conception of it. More remarkable is the role of the ad hominem retort in seeking the reassurance of one’s opponent when, on the face of it, reassurance is precisely what he (...) would seem to be ill-placed to give. Brief concluding remarks are given over to an examination of rival approaches to the ad hominem, especially those in which it is conceived of as a dialectical error. (shrink)

Contentless experience involves an absence of mental content such as thought, perception, and mental imagery. In academic work it has been classically treated as including states like those aimed for in Shamatha, Transcendental, and Stillness Meditation. We have used evidence synthesis to select and review 135 expert texts from within the three traditions. In this paper we identify the features of contentless experience referred to in the expert texts and determine whether the experiences are the same or different across the (...) practices with respect to each feature. We identify 65 features reported or implied in one or more practices, with most being reported or implied in all three. While there are broad similarities in the experiences across the traditions, we find that there are differences with respect to four features and possibly many others. The main difference identified is that Shamatha involves substantially greater attentional stability and vividness. Another key finding is that numerous forms of content are present in the experiences, including wakefulness, naturalness, calm, bliss/joy, and freedom. The findings indicate that meditation experiences described as contentless in the academic literature can in fact involve considerable variation, and that in many and perhaps most cases these experiences are not truly contentless. This challenges classical understandings in academic research that in these so-called contentless experiences all content is absent, and that the experiences are therefore an identical state of _pure consciousness_ or consciousness itself. Our assessment is that it remains an open question whether the experiences aimed for in the three practices should be classed as pure consciousness. Implications of our analysis for neuroscientific and clinical studies and for basic understandings of the practices are discussed. (shrink)

Public health and service delivery programmes, interventions and policies (collectively, ‘programmes’) are typically developed and implemented for the primary purpose of effecting change rather than generating knowledge. Nonetheless, evaluations of these programmes may produce valuable learning that helps determine effectiveness and costs as well as informing design and implementation of future programmes. Such studies might be termed ‘opportunistic evaluations’, since they are responsive to emergent opportunities rather than being studies of interventions that are initiated or designed by researchers. However, current (...) ethical guidance and registration procedures make little allowance for scenarios where researchers have played no role in the development or implementation of a programme, but nevertheless plan to conduct a prospective evaluation. We explore the limitations of the guidance and procedures with respect to opportunistic evaluations, providing a number of examples. We propose that one key missing distinction in current guidance is moral responsibility: researchers can only be held accountable for those aspects of a study over which they have control. We argue that requiring researchers to justify an intervention, programme or policy that would occur regardless of their involvement prevents or hinders research in the public interest without providing any further protections to research participants. We recommend that trial consent and ethics procedures allow for a clear separation of responsibilities for the intervention and the evaluation. (shrink)

Buttercups, GNP's and Quarks: Are Fallacies Theoretical Entities?

Background: Acting ethically, in accordance with professional and personal moral values, lies at the heart of nursing practice. However, contextual factors, or obstacles within the work environment, can constrain nurses in their ethical practice – hence the importance of the workplace ethical climate. Interest in nurse workplace ethical climates has snowballed in recent years because the ethical climate has emerged as a key variable in the experience of nurse moral distress. Significantly, this study appears to be the first of its (...) kind carried out in New Zealand. Aim/objective: The purpose of this study was to explore and describe how registered nurses working on a medical ward in a New Zealand hospital perceive their workplace ethical climate. Research design/participants/context: This was a small, qualitative descriptive study. Seven registered nurses were interviewed in two focus group meetings. An inductive method of thematic data analysis was used for this research. Ethical considerations: Ethics approval for this study was granted by the New Zealand Ministry of Health’s Central Regional Health and Disability Ethics Committee on 14 June 2012. Findings: The themes identified in the data centred on three dominant elements that – together – shaped the prevailing ethical climate: staffing levels, patient throughput and the attitude of some managers towards nursing staff. Discussion: While findings from this study regarding staffing levels and the power dynamics between nurses and managers support those from other ethical climate studies, of note is the impact of patient throughput on local nurses’ ethical practice. This issue has not been singled out as having a detrimental influence on ethical climates elsewhere. Conclusion: Moral distress is inevitable in an ethical climate where the organisation’s main priorities are perceived by nursing staff to be budget and patient throughput, rather than patient safety and care.

The vast majority of research in nursing ethics over the last decade indicates that nurses may not be fully prepared to ‘deliver the good(s)’ for their patients, or to contribute appropriately in the wider current health care climate. When suitable research projects were evaluated for this article, one key question emerged: if nurses are educationally better prepared than ever before to exercise their ethical decision-making skills, why does research still indicate that the expected practice-based improvements remain elusive? Hence, a number (...) of ideas gleaned from recent research about the current nature of nursing ethics, and especially teaching nursing ethics to student nurses, are analysed and critiqued in this article, which concludes with a cluster of ideas and conclusions based on that analysis. It is hoped that such a review may serve as a catalyst for nurse educators to re-examine their teaching practices with a view to enhancing good (i.e. ethical) nursing practice through educational means.

In the human cognitive economy there are four grades of epistemic involvement. Knowledge partitions into distinct sorts, each in turn subject to gradations. This gives a fourwise partition on ignorance, which exhibits somewhat different coinstantiation possibilities. The elements of these partitions interact with one another in complex and sometimes cognitively fruitful ways. The first grade of knowledge I call “anselmian” to echo the famous declaration credo ut intelligam, that is, “I believe in order that I may come to know”. As (...) construed here, one knows in this anselmian way that E = mc2 just in case one knows that sentence expresses a true statement, but without having to understand the proposition it expresses. Most epistemologists ignore the significance of this grade of epistemic involvement. In a second grade of epistemic involvement, knowing that E = mc2 is knowing what that sentence means and understanding the proposition it express. This is knowledge in the propositional or semantic sense, and is the dominant target of epistemological investigation. Tacit and implicit knowledge occupies another tier. A typical example would be something that someone has “known all along” but, until now, hasn’t had occasion to put her mind to it or formulate in words. TI-knowledge remains a minority interest in today’s epistemology. Operating at a fourth grade of epistemic involvement is what I call “impact”-knowledge, which is the knowledge of a matter at its deepest and most widespread. An example, to be discussed below, is the knowledge that was generated by the Wiles proof of Fermat’s last theorem. Its true importance lies not only, or even mainly, in its verification of a commonly accepted fact about numbers, but rather in its enrichment of the mathematics of elliptical curves and the promise it holds for greater advancement into the mathematical unknown. Knowledge of this fourth grade has yet to find a seat in the parliaments of epistemology. Knowledge of the anselmian sort is independent of the other three. Tacit and implicit knowledge is incompatible with anselmian and semantic knowledge but coinstantiable with impact-knowledge. Semantic knowledge is incompatible with tacit and implicit knowledge but coinstantiable with the others. Impact-knowledge is pairwise coinstantiable with the others. Below I will bring the ignorance partitions into such alignment as they have with these ones. In doing so, I’ll propose a naturalized causal response epistemology designed to give these interactive distinctions the theoretical air they need to breathe. (shrink)

RNA localization is a powerful strategy used by cells to localize proteins to subcellular domains and to control protein synthesis regionally. In germ cells, RNA targeting has profound implications for development, setting up polarities in genetic information that drive cell fate during embryogenesis. The frog oocyte offers a useful system for studying the mechanism of RNA localization. Here, we discuss critically the process of RNA localization during frog oogenesis. Three major pathways have been identified that are temporally and spatially separated (...) in oogenesis. Each pathway uses a different mechanism to effect RNA localization. In some cases, localization elements within the 3' untranslated region have been identified and have provided unique insights into the localization process. This important field is still in its infancy, however, and much remains to be learned. BioEssays 21:546–557, 1999. © 1999 John Wiley & Sons, Inc. (shrink)

In a world plagued by disagreement and conflict one might expect that the exact sciences of logic and mathematics would provide a safe harbor. In fact these disciplines are rife with internal divisions between different, often incompatible, systems. Do these disagreements admit of resolution? Can such resolution be achieved without disturbing assumptions that the theorems of logic and mathematics state objective truths about the real world? In this original and historically rich book John Woods explores apparently intractable disagreements in (...) logic and the foundations of mathematics and sets out conflict resolution strategies that evade or disarm these stalemates. An important sub-theme of the book is the extent to which pluralism in logic and the philosophy of mathematics undermines realist assumptions. This book makes an important contribution to such areas of philosophy as logic, philosophy of language and argumentation theory. It will also be of interest to mathematicians and computer scientists.

According to Schopenhauer’s compensation argument for pessimism, the non-existence of the world is preferable to its existence because no goods can ever compensate for the mere existence of evil. Standard interpretations take this argument to be based on Schopenhauer’s thesis that all goods are merely the negation of evils, from which they assume it follows that the apparent goods in life are in fact empty and without value. This article develops a non-standard variant of the standard interpretation, which accepts the (...) relevance of the negativity thesis but rejects that the argument assumes that life’s goods are all empty and valueless. Instead, it argues that whatever value negative goods might possess, they do not have the kind of value to compensate for positive evils. This involves additional development of the negativity thesis and a defence of it against objections from Byron Simmons (2021). (shrink)

This is an examination of the dialectical structure of deep disagreements about matters not open to empirical check. A dramatic case in point is the Law of Non-Contradiction . Dialetheists are notoriously of the view that, in some few cases, LNC has a true negation. The traditional position on LNC is that it is non-negotiable. The standard reason for thinking it non-negotiable is, being a first principle, there is nothing to negotiate. One of my purposes is to show that the (...) first-principle defence of LNC is inadequate. A second purpose is to argue that it flows from this inadequacy that LNC stands or falls on economic considerations, much in the spirit of Quine's pragmatism about logic generally. This is a tactical victory for dialetheists. It gives them room to make the case against LNC on cost-benefit grounds. As things presently stand, no such case can be considered decisive. But, given that costs and benefits shift with changing circumstances, it is possible that a winning case for the dialetheist may present itself in the future. Notwithstanding the rivalry between consistentists and dialetheists, they share a common opponent. This is trivialism, the doctrine that everything whatever is true. It is an ironic alliance, in as much as the dialetheist's case against the consistentist can be adapted to a defence of trivialism. How damaging this turns out to be depends on the adequacy of the reasons for the dialetheist's rejection of trivialism. My further purpose is to show that the damage is slighter than dialetheists commonly believe. (shrink)

Allies of those experiencing injustice or oppression face a dilemma: to be neutral in the face of calls to solidarity risks siding with oppressors, yet to speak or act on behalf of others risks compounding the injustice. We identify what we call ‘a normative demand for deference’ (NDD) to those with lived experience as a response to this dilemma. Yet, while the NDD is prevalent, albeit sometimes implicitly so, in contemporary solidarity theory and activist practice, it remains under-theorised. In this (...) article, we analyse the potential benefits of adhering to the NDD, highlighting both a commonly accepted epistemic benefit, and a neglected but important good in bearing witness. Yet adhering to the NDD also raises real challenges. While the literature focuses on a gold standard model of direct engagement, we defend a valuable role for a second-order form of engagement through reading, films, and similar media, which, we argue, is particularly salient for global and transnational solidarity, an important element of contemporary global politics.

Although I have little sympathy for Nagel's instrumentalism, his "dictum" on the debates over scientific realism (as Boyd refers to it) is disconcertingly accurate; it does seem as if "the already long controversy...can be prolonged indefinitely." The reason for this, however, is not that realists and instrumentalists are divided by merely terminological differences in their "preferred mode[s] of speech", indeed, this analysis appeals only if you are already convinced that realism of any robust sort is mistaken. The debates persist, instead, (...) because the most sophisticated positions on either side now incorporate self-justifying conceptions of the aim of philosophy and of the standards of adequacy appropriate for judging philosophical theories of science. Realism and anti realism thus confront one another as preferred and essentially incommensurable modes of philosophical practice; it is in this sense that they have "dialectical resources for maintaining [their positions] in face of [virtually any] criticism." In what follows I first give an analysis of the central forms of argument for realism and anti realist responses to them that shows how the locus of debate has shifted to metaphilosophical issues. This is the basis for characterizing and assessing the forms of philosophical practice that are now emerging; my thesis is that there are strong grounds for preferring realism if the competing positions are judged as comprehensive research programs.

Many philosophers endorse the ideal of justice yet disagree radically over what that ideal requires. One persistent problem for thinking about justice is that the unjust social arrangements that originally motivated our questions may also distort our thinking about possible answers. This paper suggests some strategies for improving our thinking about justice in the unjust meantime. As our world becomes more just, we may expect our thinking about justice to improve.
