The proportion of the world’s population living in urban areas is increasing rapidly, with the vast majority of this growth in developing countries. As growing populations in urban areas demand greater food supplies, coupled with a rise in rural to urban migration and the need to create livelihood options, there has been an increase in urban agriculture worldwide. Urban agriculture is commonly discussed as a sustainable solution for dealing with gaps in the local food system, and proponents often highlight the (...) many social, environmental, and economic benefits. We argue that the sustainability of urban agriculture should not be assumed. There is a need for research to take a bottom-up approach, exploring the influence that city-level conditions have on livelihood decisions by farmers and how this shapes the practice of urban agriculture. This paper uses a case study for an in-depth look at urban agriculture in Delhi, India to understand from the farmers’ perspective how urban agriculture is practiced and what factors influence farmers’ livelihood decisions. Using a team-based, multi-method Rapid Assessment Process, data were collected through preliminary key informant interviews, field observations, semi-structured interviews with urban farmers, and geographic information systems mapping. This research provides an in-depth description of market-oriented urban agriculture in a developing country, explores how farmers’ livelihood decisions are embedded in the urban context, and discusses the potential of urban agriculture as a sustainable city-system.

BackgroundDecision-making in initiating life-sustaining health technology is complex and often conducted at time-critical junctures in clinical care. Many of these decisions have profound, often irreversible, consequences for the child and family, as well as potential benefits for functioning, health and quality of life. Yet little is known about what influences these decisions. A systematic review of reasoning identified the range of reasons clinicians give in the literature when initiating technology dependence in a child, and as a result helps determine the (...) range of influences on these decisions.MethodsMedline, EMBASE, CINAHL, PsychINFO, Web of Science, ASSIA and Global Health Library databases were searched to identify all reasons given for the initiation of technology dependence in a child. Each reason was coded as a broad and narrow reason type, and whether it supported or rejected technology dependence.Results53 relevant papers were retained from 1604 publications, containing 116 broad reason types and 383 narrow reason types. These were grouped into broad thematic categories: clinical factors, quality of life factors, moral imperatives and duty and personal values; and whether they supported, rejected or described the initiation of technology dependence. The majority were conceptual or discussion papers, less than a third were empirical studies. Most discussed neonates and focused on end-of-life care.ConclusionsThere is a lack of empirical studies on this topic, scant knowledge about the experience of older children and their families in particular; and little written on choices made outside ‘end-of-life’ care. This review provides a sound basis for empirical research into the important influences on a child’s potential technology dependence. (shrink)

Unrealistic optimism is a bias that leads people to believe, with respect to a specific event or hazard, that they are more likely to experience positive outcomes and/or less likely to experience negative outcomes than similar others. The phenomenon has been seen in a range of health-related contexts—including when prospective participants are presented with the risks and benefits of participating in a clinical trial. In order to test for the prevalence of unrealistic optimism among participants of early-phase oncology trials, we (...) conducted a survey with patients over 18 years of age who were enrolled in a phase I, phase I/II, or phase II clinical cancer trial in the New York City area between August 2008 and October 2009. Participants in our study were asked to compare their own chances of experiencing a range of risks and benefits related to the trial they were enrolled in with the chances of the other trial participants. We found a significant optimistic bias in their responses. Respondents tended to overestimate the benefits of the trial they were enrolled in and underestimate its risks. In addition, we found no significant relationship between respondents’ understanding of the trial’s purpose and how susceptible they were to unrealistic optimism. Our findings suggest that improving the consent process for oncology studies requires more than addressing deficits in understanding. (shrink)

Background Maternal mental health during the peripartum period is critically important to the wellbeing of mothers and their infants. Numerous studies and clinical trials have focused on various aspects of interventions and treatments for perinatal mental health from the perspective of researchers and medical health professionals. However, less is known about women’s experiences of participating in perinatal mental health research, and the ethical issues that arise. Aim To systematically review the literature on the ethical issues that emerge from pregnant and/or (...) postpartum women’s experiences of taking part in perinatal mental health-related research. Methods Systematic review of nine bibliographic databases, from inception to July 2021. Qualitative, quantitative and mixed method studies were included if they reported on ethical issues experienced by perinatal women. Research ethical issues encompassed any issue relating to women’s experiences of being offered study information, recruitment, consent, retention and respect for autonomy. Titles, abstracts and full text screening, appraisal of the methodological quality of included studies, and data extraction, were conducted independently by two reviewers. Ethical considerations Ethical approval was not required for this systematic review. Findings A total of 9830 unique citations was retrieved. Six studies met the inclusion criteria. Studies were clinically and methodologically heterogenous, and only one was purposively designed to explore women’s experiences. The key finding was the establishment of trust between the researcher and participant in all stages of the research process. Findings are presented according to recruitment and consent processes, participation and retention, and study follow-up and completion. Conclusion The establishment of trust between the researcher and perinatal women leads to a dynamic with research ethical implications relevant to all stages of perinatal mental health-related research. Further research on the research ethical issues experienced by perinatal women is required because of the limited literature. (shrink)

Drawing on a landscape analysis of existing data-sharing initiatives, in-depth interviews with expert stakeholders, and public deliberations with community advisory panels across the U.S., we describe features of the evolving medical information commons. We identify participant-centricity and trustworthiness as the most important features of an MIC and discuss the implications for those seeking to create a sustainable, useful, and widely available collection of linked resources for research and other purposes.

Background During the COVID-19 pandemic, virtual visiting technologies were rapidly integrated into the care offered by intensive care units (ICUs) in the UK and across the globe. Today, these technologies offer a necessary adjunct to in-person visits for those with ICU access limited by geography, work/caregiving commitments, or frailty. However, few empirical studies explore the ethical issues associated with virtual visiting. This study aimed to explore the anticipated or unanticipated ethical issues raised by using virtual visiting in the ICU, such (...) that healthcare professionals can be informed about how to carry out virtual visits ethically, safely and productively. Methods We used a descriptive exploratory qualitative research approach recruiting a convenience sample of newly-graduated junior doctors facilitating ICU virtual visits in a tertiary academic centre. Eight newly graduated junior doctors, seven female and one male, aged 23–27, participated in semi-structured interviews. We analysed transcripts using an inductive coding approach. Results Five overarching themes emerged. Two of the themes namely, ‘fulfilling a moral instinct to connect families’ and ‘promoting autonomy’, arose from participants’ descriptions of how virtual visits aligned with healthcare standards and practices they considered ethical. Three further themes, ‘preserving dignity and privacy’, ‘managing emotional distress’, and ‘providing equitable access’ to virtual visiting technologies, highlight how virtual visits might exacerbate ethical issues related to family communications. Conclusion Virtual visiting may potentially both ameliorate and exacerbate aspects of ethical healthcare delivery for ICU patients and family members. ICU team members should consider unique ethical considerations related to using virtual visiting. We recommend virtual communications skills training for staff and advocate for the use of easily accessible educational resources for families who wish to visit critically unwell patients remotely.

This text is a result of two long conversations between Ferran Adrià and Jèssica Jaques at elBulliLab, the creativity laboratory directed by the Catalan cook, in January, 2016. It has been translated from Catalan by Tiam Goudarzi under the supervision of the author.

In “The Runabout Inference Ticket” AN Prior (1960) examines the idea that logical connectives can be given a meaning solely in virtue of the stipulation of a set of rules governing them, and thus that logical truth/consequence.

In lieu of an abstract, here is a brief excerpt of the content:The Ontological Status of Malebranchean IdeasMonte CookOnce again... we are brought back to a fundamental problem in Malebranche’s theory of ideas. What is the ontological status or nature of ideas? They are neither substances nor modifications of any substance. Yet in the Cartesian schema these are the only alternatives: something is either a substance or a modification of a substance. And Malebranche, however modified his Cartesianism, is at least (...) explicit in accepting this ontological dualism.(Steven Nadler, Malebranche and Ideas, 96.)Nadler nicely states a problem for Malebranchean scholarship: What, for Malebranche, is the ontological status of ideas? Despite their importance to his theory of vision in God, Malebranche seems to leave no metaphysical place for them. He seems to hold three jointly inconsistent positions—that everything is either a substance or a modification of a substance, that ideas are not sub-stances, and that ideas are not modifications.1 Since he clearly denies both that ideas are substances and that they are modifications, on the face of it the only way out of this apparent inconsistency is for him to reject the principle that everything is either a substance or a modification of a substance. And indeed, according to one common interpretation Malebranche restricts the dualism of substances and modifications to created things, thus excluding ideas.2I shall argue that Malebranche can and does consistently hold all three [End Page 525] positions. He escapes inconsistency by maintaining that although ideas fit into the category of substance, they are not different substances. Rather than being substances (plural), they are identical with one substance, God.I am of course not alone in seeing this identification of ideas with the substance of God. Nadler, for example, notes it but thinks that it fails to get Malebranche out of the problem of holding three jointly inconsistent positions.3 Nicholas Jolley not only notes it, but also thinks that it provides Malebranche an escape from inconsistency, if only on a surface level. For Jolley, the real problem is that ideas have features incompatible with their being identified with God: in particular, ideas are abstract entities whereas God is not an abstract entity. Though Malebranche admittedly does identify ideas with the substance of God, then, there is a sense in which he cannot really do this.4The problem Jolley raises is part of the larger problem of how ideas can be identical with the substance of God. Though I will not discuss Jolley’s problem directly, I hope that my discussion of the relation between ideas and the substance of God will throw light on what Jolley takes to be the real problem with identifying ideas with God. I will content myself with showing that Malebranche does hold all three positions in question and explaining how he develops his identification of ideas with the substance of God. In what follows, then, I shall first establish that Malebranche holds the three positions in question, and in particular that he does not restrict the principle that everything is either a substance or a modification to created things. I shall then show how he identifies ideas with the substance of God. Finally, I shall discuss a contrary passage in which Malebranche explicitly denies that intelligible extension (i.e., the idea of extension) is either a substance or a modification.11.1.Malebranche states the principle that everything is either a substance or a mode (or equivalently, a being or a mode) throughout his writings.5 Though he occasionally uses the principle only as it applies to the created world (see LO 237), he almost always states it as applying to everything, created or uncreated: “everything which is, whether it actually exists or not, and consequently [End Page 526] everything intelligible, reduces to being and mode” (LO 639).6 He treats it as a conceptual matter, and thus a necessary truth, that everything must be one or the other: everything “is necessarily either a substance or a mode of being. For in the end all that is can either be conceived of alone or it cannot; there is no middle in contradictory propositions” (LO 513).Reflecting on how Malebranche understands the principle makes...

A number of formal constraints on acceptable abstraction principles have been proposed, including conservativeness and irenicity. Hume’s Principle, of course, satisfies these constraints. Here, variants of Hume’s Principle that allow us to count concepts instead of objects are examined. It is argued that, prima facie, these principles ought to be no more problematic than HP itself. But, as is shown here, these principles only enjoy the formal properties that have been suggested as indicative of acceptability if certain constraints on the (...) size of the continuum hold. As a result, whether or not these higher-order versions of Hume’s Principle are acceptable seems to be independent of standard (ZFC) set theory. This places the abstractionist in an uncomfortable dilemma: Either there is some inherent difference between counting objects and counting concepts, or new criteria for acceptability will need to be found. It is argued that neither horn looks promising. (shrink)

To better understand the available publications addressing ethical issues in rural health care we sought to identify the ethics literature that specifically focuses on rural America. We wanted to determine the extent to which the rural ethics literature was distributed between general commentaries, descriptive summaries of research, and original research publications. We identified 55 publications that specifically and substantively addressed rural health care ethics, published between 1966 and 2004. Only 7 (13%) of these publications were original research articles while (12) (...) 22% were descriptive summaries of research and 36 (65%) were general commentaries. The majority of publications examined (55%) were clinically focused while 27% addressed organizational ethics and 18% addressed ethical ramifications of rural health care policy at a national or community level. Our findings indicate that there are a limited number of publications focusing on rural health care ethics, suggesting a need for scholars and researchers to more rigorously address rural ethics issues.

Susan Goldin-Meadow is the 2021 Recipient of the Rumelhart Prize. Goldin-Meadow's body of research addresses the roles of gesture in language creation, communication, learning, and cognition. In one major strand of her research, Goldin-Meadow has studied gestures in children who are not exposed to any structured language input, specifically, deaf children of hearing parents who do not expose their children to sign language. These children create a highly structured, language-like system with their hands—a homesign. In another major strand, Goldin-Meadow has (...) focused on the gestures that people produce along with speech. She has examined how gestures contribute to producing and comprehending language at the moment of speaking or signing, how gestures contribute to learning language and to learning other concepts and skills, and how gestures may actually constitute and change people's thinking. This topic collection is made up of papers that represent and extend these strands of Goldin-Meadow's work. This introductory article provides a brief biography of Goldin-Meadow, and it highlights ways in which the contributions to the topic collection exemplify several notable characteristics of Goldin-Meadow's body of work, including (1) a focus on multiple timescales of behavior and behavior change; (2) use of diverse methods, approaches, and populations; and (3) considerations of equity and inclusion, both in research and in educational and clinical practice.

Often implicit in visual display design and development is a gold standard of photorealism. By approximating direct perception, photorealism appeals to users and designers by being both attractive and apparently effortless. The vexing result from numerous performance evaluations, though, is that increasing realism often impairs performance. Smallman and St. John (2005) labeled misplaced faith in realistic information display Naïve Realism and theorized it resulted from a triplet of folk fallacies about perception. Here, we illustrate issues associated with the wider trend (...) towards realism by focusing on a specific current trend for high-fidelity perspective view (3D) geospatial displays. In two experiments, we validated Naïve Realism for different terrain understanding tasks, explored whether certain individuals are particularly prone to Naïve Realism, and determined the ability of task feedback to mitigate Naïve Realism. Performance was measured for laying and judging a concealed route across realistic terrain shown in different display formats. Task feedback was either implicit, in Experiment 1, or explicit in Experiment 2. Prospective and retrospective intuitions about the best display formats for the tasks were recorded and then related to task performance and participant spatial ability. Participants generally intuited they would perform tasks better with more realism than they actually required. For example, counter to intuitions, lowering fidelity of the terrain display revealed the gross scene layout needed to lay a well-concealed route. Individuals of high spatial ability calibrated their intuitions with only implicit task feedback, whereas those of low spatial ability required salient, explicit feedback to calibrate their intuitions about display realism. Results are discussed in the wider context of applying perceptual science to display design, and combating folk fallacies. (shrink)

It is shown that the logical truth of instances of the T-schema is incompatible with the formal nature of logical truth. In particular, since the formality of logical truth entails that the set of logical truths is closed under substitution, the logical truth of T-schema instances entails that all sentences are logical truths.

Williams, Elster and Pears hold that an effort to induce in oneself a belief in the truth of some proposition that one believes to be false can succeed only if one manages, somewhere along the way, to forget that one is engaged in such an effort. Although this view has strong intuitive appeal, it is false, and in this paper it is shown to be false by example.

The main result established in this paper is the following: If the base normed spaceV of completely additive weights is a norm-determining subspace of the space of finitely additive weights V acting on the order unit space spanning the operational logic, thenV has the ε-Jordan-Hahn property iff V has the approximate Jordan-Hahn property. Several examples illustrating the theory are given.

Truth values are, properly understood, merely proxies for the various relations that can hold between language and the world. Once truth values are understood in this way, consideration of the Liar paradox and the revenge problem shows that our language is indefinitely extensible, as is the class of truth values that statements of our language can take – in short, there is a proper class of such truth values. As a result, important and unexpected connections emerge between the semantic paradoxes (...) and the set-theoretic paradoxes. (shrink)

Timothy Williamson’s Modal Logic as Metaphysics is a book-length defense of necessitism about objects—roughly put, the view that, necessarily, any object that exists, exists necessarily. In more formal terms, Williamson argues for the validity of necessitism for objects (NO: ◻︎∀x◻︎∃y(x=y)). NO entails both the (first-order) Barcan formula (BF: ◇∃xΦ → ∃x◇Φ, for any formula Φ) and the (first-order) converse Barcan formula (CBF: ∃x◇Φ → ◇∃xΦ, for any formula Φ). The purpose of this essay is not to assess Williamson’s arguments either (...) for necessitism (although discussion of these arguments will play a central role in the dialectic) or for necessitism’s two famous corollaries. Instead, the focus shall be a general principle governing abstract objects—the abstract of principle (or AOP) —instances of which seems to be at work in some of Williamson’s central arguments for necessitism. The AOP can be straightforwardly formulated and applied within the neo-logicist framework—in fact, arguably the principle is most naturally formulated in neo-logicist terms. -/- After closely examining, and carefully formalizing, the AOP, the remainder of the paper focuses on arguments for necessitism-like claims (the exact meaning of “necessitism-like” will become clearer as the essay progresses) based on the AOP. In particular, we shall focus on the instance of the AOP that applies to the abstract objects governed by the most well-known and most fully studied abstraction principle: Hume’s Principle (HP). It turns out that, although we cannot reconstruct a valid argument for necessitism based on this numerical instance of the AOP, we can obtain valid arguments for weaker, but equally interesting conclusions. In particular, we shall show that, although HP combined with the AOP (and some additional, related assumptions) allows the contents of the domains of possible worlds to vary, the size of those domains must remain constant. The paper concludes by developing and critiquing some related arguments for necessitism based on applying relevant instances of the AOP to abstraction principles governing sets (or extensions), and to a simple objectual abstraction principle.

The No-No Paradox consists of a pair of statements, each of which ?says? the other is false. Roy Sorensen claims that the No-No Paradox provides an example of a true statement that has no truthmaker: Given the relevant instances of the T-schema, one of the two statements comprising the ?paradox? must be true (and the other false), but symmetry constraints prevent us from determining which, and thus prevent there being a truthmaker grounding the relevant assignment of truth values. Sorensen's view (...) is mistaken: situated within an appropriate background theory of truth, the statements comprising the No-No Paradox are genuinely paradoxical in the same sense as is the Liar (and thus, on Sorensen's view, must fail to have truth values). This result has consequences beyond Sorensen's semantic framework. In particular, the No-No Paradox, properly understood, is not only a new paradox, but also provides us with a new type of paradox, one which depends upon a general background theory of the truth predicate in a way that the Liar Paradox and similar constructions do not.

“Nature, Red in Tooth and Claw” explores Adorno’s ideas about our mediated relationship with nature. The first section of the paper examines the epistemological significance of his thesis about the preponderance of the object while describing the Kantian features in his notion of mediation. Adorno’s conception of nature will also be examined in the context of a review of J. M. Bernstein’s and Fredric Jameson’s attempts to characterize it. The second section of the paper deals with Adorno’s Freudian account of (...) internal nature. While arguing against Joel Whitebook’s view that Adorno needs a concept of sublimation, I contend that Adorno’s genetic account of the relationship between nature and mind enables him to respond to the Freudian injunction to displace the id with the ego with a view to fostering autonomy. In the final section of the paper, problems with Adorno’s ideas about external and internal nature are briefly discussed. (shrink)

Clinical research is increasingly conducted in settings that include private physicians’ offices, clinics, community hospitals, local institutes, and independent research centers. The migration of such research into this new, non–academic environment has brought new cadres of researchers into the clinical research enterprise and also broadened the pool of potential research participants. Regulatory approaches for protecting human subjects who participate in research have also evolved. Some institutions retain their own Institutional Review Boards (IRBs), but Independent IRBs, community hospital IRBs and community–based (...) IRBs also fulfill oversight responsibilities. This article sheds light on this evolving world by discussing the findings gleaned from two studies: a study of the decision making processes used by members who serve on different kinds of IRBs and a study of the decision making processes employed by research participants. The article then discusses how the key findings may inform proposed revisions to the Common Rule. (shrink)

RÉSUMÉ : Dans son récent recueil d’articles Language, Truth and History, Donald Davidson semble pencher en faveur d’une philosophie du langage mettant l’accent sur la notion de l’intention communicative du sujet parlant; en quoi il se rapproche du point de vue de Paul Grice. Si cela est juste, la pensée de Davidson se serait dégagée de l’approche sémantique formelle qu’il soutenait dans ses Inquiries into Truth and Interpretation. Dans cet article, je soutiens que, bien qu’il y ait beaucoup de similitudes (...) entre ces deux penseurs, Davidson n’a pas abandonné ses précédentes vues sur le langage. (shrink)

It is sometimes suggested that impure sets are spatially co-located with their members (and hence are located in space). Sets, however, are in important respects like numbers. In particular, sets are connected to concepts in much the same manner as numbers are connected to concepts—in both cases, they are fundamentally abstracts of (or corresponding to) concepts. This parallel between the structure of sets and the structure of numbers suggests that the metaphysics of sets and the metaphysics of numbers should parallel (...) each other in relevant ways. This entails, in turn, that impure sets are not co-located with their members (nor are they located in space). (shrink)

Macphail’s comparative approach to intelligence focused on associative processes, an orientation inconsistent with more multifaceted lay and scientific understandings of the term. His ultimate emphasis on associative processes indicated few differences in intelligence among vertebrates. We explore options more attuned to common definitions by considering intelligence in terms of richness of representations of the world, the interconnectivity of those representations, the ability to flexibly change those connections, knowledge, and individual differences. We focus on marine mammals, represented by the amphibious pinnipeds (...) and the aquatic cetaceans and sirenians, as animals that transitioned from a terrestrial existence to an aquatic one, experiencing major changes in ecological pressures. They adapted with morphological transformations related to streamlining the body, physiological changes in respiration and thermoregulation, and sensory/perceptual changes, including echolocation capabilities and diminished olfaction in many cetaceans, both in-air and underwater visual focus, and enhanced senses of touch in pinnipeds and sirenians. Having a terrestrial foundation on which aquatic capacities were overlaid likely affected their cognitive abilities. Vocal and behavioral observational learning capabilities in the wild and in laboratory experiments suggest versatility in group coordination. Empirical reports on aspects of intelligent behavior like problem-solving, spatial learning, and concept learning by various species of cetaceans and pinnipeds, suggest rich cognitive abilities. The high energy demands of the brain suggest brain-intelligence relationships might be fruitful areas for the study when specific hypotheses are considered, e.g., brain mapping indicates hypertrophy of specific sensory areas in marine mammals. Modern neuroimaging techniques provide ways to study neural connectivity, and the patterns of connections between sensory, motor, and other cortical regions provide a biological framework for exploring how animals represent and flexibly use information in navigating and learning about their environment. At this stage of marine mammal research, it would still be prudent to follow Macphail’s caution that it is premature to make strong comparative statements without more empirical evidence, but an approach that includes learning more about how animals flexibly link information across multiple representations could be a productive way of comparing species by allowing them to use their specific strengths within comparative tasks.

The article explores the character of Adorno’s materialism while fleshing out his Marxist-inspired idea of natural history. Adorno offers a non-reductionist and non-dualistic account of the relationship between matter and mind, human history and natural history. Emerging from nature and remaining tied to it, the human mind is nonetheless qualitatively distinct from nature owing to its limited independence from it. Yet, just as human history is always also natural history, because human beings can never completely dissociate themselves from the natural (...) world, nature is inextricably entwined with human history. Owing to the entwinement of mind and matter, humanity and nature, a version of dialectical materialism can be found in Adorno’s work. Key Words: body • dialectics • Hegel • history • idealism • Marx • materialism • mind • nature • Timpanaro. (shrink)

Computer-mediated interaction on the Internet provides new opportunities to examine the links between reputation, risk, and the development of trust between individuals who engage in various types of exchange. In this article, we comment on the application of experimental sociological research to different types of computer-mediated social interactions, with particular attention to the emergence of what we call ‘trust networks’ (networks of those one views as trustworthy). Drawing on the existing categorization systems that have been used in experimental social psychology, (...) we relate the various forms of computer-mediated exchange to selected findings from experimental research. We develop a simple typology based on the intersection of random versus fixed-partner social dilemma games, and repeated versus one-shot interaction situations. By crossing these two types of social dilemma games and two types of interaction situations, we show that many forms of Internet exchange can be categorized effectively into four mutually exclusive categories. The resulting classification system helps to integrate the existing research on t rust in experimental social psychology with the emerging field of computer-mediated exchange. (shrink)
