The defense of plants against herbivores and pathogens involves the participation of an enormous range of different metabolites, some of which act directly as defensive weapons against enemies (toxins or deterrents) and some of which act as components of the complex internal signaling network that insures that defense is timed to enemy attack. Recent work reveals a surprising trend: The same compounds may act as both weapons and signals of defense. For example, two groups of well‐studied defensive weapons, glucosinolates and (...) benzoxazinoids, trigger the accumulation of the protective polysaccharide callose as a barrier against aphids and pathogens. In the other direction, several hormones acting in defense signaling (and their precursors and products) exhibit activity as weapons against pathogens. Knowing which compounds are defensive weapons, which are defensive signals and which are both is vital for understanding the functioning of plant defense systems. (shrink)

The _Physics_ is a foundational work of western philosophy, and the crucial one for understanding Aristotle's views on matter, form, essence, causation, movement, space, and time. This richly annotated, scrupulously accurate, and consistent translation makes it available to a contemporary English reader as no other does—in part because it fits together seamlessly with other closely associated works in the New Hackett Aristotle series, such as the _Metaphysics_, _De Anima_, and forthcoming _De Caelo_ and _On Coming to Be and Passing Away_. (...) Eventually the series will include all of Aristotle's works. Sequentially numbered endnotes provide the information most needed at each juncture, while a detailed Index of Terms indicates places where focused discussion of key notions occurs. An illuminating general Introduction describes the book that lies ahead, explaining what sort of work it is and what sorts of evidence it relies on. (shrink)

ABSTRACTThis article studies multi-stakeholder initiatives as spaces for both deliberation and contestation between constituencies with competing discourses and disputed values, beliefs, and preferences. We review different theoretical perspectives on MSIs, which see them mainly as spaces to find solutions to market problems, as spaces of conflict and bargaining, or as spaces of consensus. In contrast, we build on a contestatory deliberative perspective, which gives equal value to both contestation and consensus. We identify four types of internal contestation which can be (...) present in MSIs—procedural, inclusiveness, epistemic, and ultimate-goal—and argue that embracing contestation and engaging in ongoing revision of provisional agreements, criteria, and goals can enhance the democratic quality of MSIs. Finally, we explore the implications of this perspective for theorizing about the democratic quality in MSIs and about the role of corporations in transnational governance. (shrink)

ABSTRACT A trivalent theory of indicative conditionals automatically enforces Stalnaker's thesis – the equation between probabilities of conditionals and conditional probabilities. This result holds because the trivalent semantics requires, for principled reasons, a modification of the ratio definition of conditional probability in order to accommodate the possibility of undefinedness. I explain how this modification is motivated and how it allows the trivalent semantics to avoid a number of well-known triviality results, in the process clarifying why these results hold for many (...) bivalent theories. In short, the slew of triviality results published in the last 40-odd years need not be viewed as an argument against Stalnaker's thesis: it can be construed instead as an argument for abandoning the bivalent requirement that indicative conditionals somehow be assigned a truth-value in worlds in which their antecedents are false.

Background: Positioned at the frontlines of the battle against COVID-19 disease, nurses are at increased risk of contraction, yet as they feel obligated to provide care, they also experience ethical pressure. Research question and objectives: The study examined how Israeli nurses respond to ethical dilemmas and tension during the COVID-19 outbreak, and to what extent this is associated with their perceived risk and motivation to provide care? Research design: The study implemented a descriptive correlative study using a 53-section online questionnaire, (...) including 4 open-ended questions. Participants and research context: The questionnaire was complete by 231 registered and intern nurses after being posted on nurses’ Facebook and WhatsApp groups, and through snowball sampling. Ethical considerations: The research was pre-approved by the ethics committee of the Faculty of Social Welfare and Health Sciences at the University of Haifa, Israel. Findings: In all, 68.8% of the respondents had received some form of training about COVID-19. Respondents positioned themselves at perceived high risk levels for contracting the virus. About one-third feared going to work because of potential contraction and due to feeling inadequately protected. While 40.9% were scared to care for COVID-19 patients, 74.7% did not believe they have the right to refuse to treat certain patients. When asked about defining an age limit for providing patients with scarce resources (such as ventilation machines) in cases of insufficient supplies, respondents stated that the maximum age in such scenarios should be 84 (standard deviation (SD = 19) – yet most respondents (81.4%) believed that every patient has the right to receive optimal treatment, regardless of their age and medical background. Discussion: Correlating with their strong commitment to care, nurses did not convey intention to leave the profession despite their stress, perceived risk, and feelings of insufficient support and protection at work. The nurses did not hold a utilitarian approach to resource allocation, thereby acknowledging the value of all people and their entitlement to care, regardless of optimal outcomes. Conclusion: While experiencing significant personal risk and emotional burden, nurses conveyed strong dedication to providing care, and did not regret working in the nursing profession, yet they did seek a supportive climate for their needs and ethical concerns.

Predictive processing has recently been advanced as a global cognitive architecture for the brain. I argue that its commitments concerning the nature and format of cognitive representation are inadequate to account for two basic characteristics of conceptual thought: first, its generality—the fact that we can think and flexibly reason about phenomena at any level of spatial and temporal scale and abstraction; second, its rich compositionality—the specific way in which concepts productively combine to yield our thoughts. I consider two strategies for (...) avoiding these objections and I argue that both confront formidable challenges. (shrink)

Recent years have seen a substantial increase in alternative agrifood initiatives that attempt to use the market to curtail the negative social and environmental effects of production and trade in a globalized food system. These alternatives pose a challenge to capital accumulation and the externalization of environmental costs by large agribusiness, trading and retail firms. Yet the success of these alternatives also makes them an inviting target for corporate participation. This article examines these dynamics through a case study of the (...) two most significant such food system alternatives—organics and fair trade—focusing on corporate involvement in establishing and renegotiating the standards undergirding these initiatives. We compare the development of and contestation over the standards for both certified organic and certified fair trade, with particular attention to the U.S. context. We provide a brief history of their parallel processes of rapid growth and market mainstreaming. We examine claims of cooptation by movement participants, as well as the divergences and similarities between the organic and fair trade cases. Analyzing these two cases provides useful insights into the strategic approaches that corporate firms have deployed to further capital accumulation and to defuse threats to their profit margins and to status quo production, pricing, labor, trading and retailing practices. It can also offer valuable lessons regarding the most effective means of responding to such counter-reforms and of protecting or reasserting the more transformative elements at the heart of these alternative systems.

The notion of ‘revealed preference’ is unclear and should be abandoned. Defenders of the theory of revealed preference have misinterpreted legitimate concerns about the testability of economics as the demand that economists eschew reference to (unobservable) subjective states. As attempts to apply revealed-preference theory to game theory illustrate with particular vividness, this demand is mistaken.

On a Dreyfusian account performers choke when they reflect upon and interfere with established routines of purely embodied expertise. This basic explanation of choking remains popular even today and apparently enjoys empirical support. Its driving insight can be understood through the lens of diverse philosophical visions of the embodied basis of expertise. These range from accounts of embodied cognition that are ultra conservative with respect to representational theories of cognition to those that are more radically embodied. This paper provides an (...) account of the acquisition of embodied expertise, and explanation of the choking effect, from the most radically enactive, embodied perspective, spelling out some of its practical implications and addressing some possible philosophical challenges. Specifically, we propose: an explanation of how skills can be acquired on the basis of ecological dynamics; and a non-linear pedagogy that takes into account how contentful representations might scaffold skill acquisition from a radically enactive perspective.

This book is a study of the role of intellect in human action as described by Thomas Aquinas. One of its primary aims is to compare the interpretation of Aristotle by Aquinas with the lines of interpretation offered in contemporary Aristotelian scholarship. The book seeks to clarify the problems involved in the appropriation of Aristotle's theory by a Christian theologian, including such topics as the practical syllogism and the problems of akrasia. Westberg argues that Aquinas was much closer to Aristotle (...) than is often recognized, and he puts forward important new interpretations of the relation of intellect and will in the stages of intention, deliberation, decision, and execution. In the concluding section of the book, he shows how this new interpretation yields fruitful insights on a range of theological topics, including sin, law, love, and the moral virtues. (shrink)

John Stuart Mill regards economics as an inexact and separate science which employs a deductive method. This paper analyzes and restates Mill's views and considers whether they help one to understand philosophical peculiarities of contemporary microeconomic theory. The author concludes that it is philosophically enlightening to interpret microeconomics as an inexact and separate science, but that Mill's notion of a deductive method has only a little to contribute.

This paper responds to Alva Noë’s general critique of Radical Enactivism. In particular, it responds to his claim that Radical Enactivism denies experience, presence and the world. We clarify Radical Enactivism’s actual arguments and positive commitments in this regard. Finally, we assess how Radical Enactvism stands up in comparison with Noë’s own version of Sensorimotor Knowledge Enactivism.

During the early nineteenth century the Royal Observatory, Greenwich, significantly increased the number of individuals it employed. One of the new roles created was the position of First Assistant, who oversaw the management of astronomical labor at the observatory. This article examines the contribution of Robert Main, who was the first person employed in this role. It shows that, through Robert Main’s duties and tasks, the observatory appears as a hybrid site embodying aspects of the other institutions that formed part (...) of its operational network. Moreover, it demonstrates that the transformation of the observatory during the nineteenth century was driven by his rigorous maintenance of discipline in relation to the daily operations of the site.

In their development of causal decision theory, Allan Gibbard and William Harper advocate a particular method for calculating the expected utility of an action, a method based upon the probabilities of certain counterfactuals. Gibbard and Harper then employ their method to support a two-box solution to Newcomb’s paradox. This paper argues against some of Gibbard and Harper’s key claims concerning the truth-values and probabilities of counterfactuals involved in expected utility calculations, thereby disputing their analysis of Newcomb’s Paradox. If we are (...) right, then Gibbard and Harper’s method of calculating expected utility does not adequately represent rational choice. (shrink)

Over the past few decades, large food banks that collect, warehouse, and redistribute food have become institutionalized across Europe. Although food banks gained increased visibility as important food relief mechanisms during the covid pandemic in 2020 and 2021, the crisis also highlighted their structural weaknesses and the fragility of the charity-based emergency food system. In particular, many European food banks faced higher costs, lower food stocks, uneven food donations, and lower numbers of volunteers and personnel as demand for food relief (...) increased sharply. Also, many food banks lacked personal health and safety equipment for front-line staff and volunteers, many of whom were vulnerable or aged, thus forcing the closure of some charities due to health concerns. Yet, the impact of the pandemic was uneven across the continent as the covid pandemic strengthened some food banks while others were weakened. To explore these dynamics in detail, this paper utilizes in-depth interviews and surveys of key food bank operators in the Netherlands, Norway, and Greece to analyze how and why European food bank systems fared so differently from the pandemic. In short, the findings in this paper reveal how the Norwegian food bank system leveraged its position to increase fundraising and visibility, while the Netherlands food bank system suffered from long-term structural weaknesses, and the Greek food bank system was further embroiled in government tensions that threatened its existence. The preexisting structure of food bank systems, broader political economy, and historical context significantly impacted how food relief networks fared during the pandemic. (shrink)

Classic serotonergic psychedelics are experiencing a clinical revival, which has also revived ethical debates about psychedelic-assisted therapy. A particular issue here is how to prepare and protect patients from the vulnerability that the psychedelic state creates. This article first examines how this vulnerability manifests itself, revealing that it results from an impairment of autonomy: psychedelics diminish decision-making capacity, reduce controllability, and limit resistance to external influences. It then analyzes the strengths and weaknesses of five safety measures proposed in the literature, (...) what aspect of the patient’s vulnerability they seek to reduce, and how they can be optimized. The analysis shows that while preparatory sessions, advance directives, and specific training and oversight are useful, starting with a lower dosage and no therapy is less so. Finally, the article presents a safety measure that has been overlooked in the literature but could be highly effective and feasible: bringing a close person to the psychedelic session. (shrink)

Scientific psychology and neuroscience are taking increasingly precise and comprehensive pictures of the human mind, both in its physi- cal architecture and its functional processes. Meanwhile, each human mind has an abbreviated view of itself, a self-portrait that captures how it thinks it operates, and that therefore has been remarkably influential. The mind’s self-portrait has as a central feature the idea that thoughts cause actions, and that the self is thus an origin of the body’s actions. This self- portrait is (...) reached through a process of inference of apparent mental cau- sation, and it gives rise to the experience that we are consciously willing what we do. Evidence from several sources suggests that this self-portrait may often be a humble and misleading caricature of the mind’s opera- tion—but one that underlies the feeling of authorship and the acceptance of responsibility for action.

This paper explores the possibility of extending Locke’s theory with respect to tangible property so that it might offer a feasible theoretical basis for intellectual property too. The main conclusion is that such an attempt must fail. Locke’s theory comes in three parts: a general justification of property which serves to explain why assets ought to be under the exclusive control of individuals; a positive method of private appropriation whereby an individual acquires a prima facie exclusive claim to previously commonly (...) held natural resources; and third, a negative requirement that other individuals’ crucial interests are not harmed by such an appropriation. For each of these, the difficulties involved in applying that part of the theory to the sphere of ideas are discussed, and a central aspect of intellectual property that raises the problems of application is highlighted.

The Declaration on Euthanasia (1980) defined euthanasia as “an action or an omission which of itself or by intention causes death, in order that all suffering may in this way be eliminated.” In Evangelium vitae (1995) Pope St. John Paul II defined “euthanasia in the strict sense” using exactly the same words, except that where the declaration has “of itself or [vel] by intention” the encyclical reads “of itself and [et] by intention.” This paper explores the significance of this change, (...) which has been largely ignored and has not been adopted by the Catechism or by the Ethical and Religious Directives. I argue for the superiority of the definition in the declaration. (shrink)

In her work Horrendous Evils and the Goodness of God, Marilyn McCord Adams offers an account of the problem of evil that deals with the interaction between certain types of evil and the human capacity for meaning production. This paper attempts to consider certain implications of her presuppositions and, in so doing, to uncover several challenges to her broader project entailed by said implications. More specifically, this paper considers, within the context of Adams’ broader project, the status of perpetrators of (...) horrendous evils with respect to their ability to conceive of said evils, evils that destroy meaning-making capacities in their victims and evils that twist and subvert the meaning-making processes of their victims or observers.

L’auteur donne un bref survol de la notion d’entre-deux comme dynamique où émergent, se croisent et évoluent les interactions entre deux pôles différents ou opposés. Cette dynamique va à l’encontre du clivage, si fréquent dans les discours et les pensées quand on a peur d’intégrer deux termes antinomiques, ne voyant pas que l’entre-deux offre un tiers ou une ligne de fuite pour échapper au blocage. L’auteur montre que cette dynamique a porté et fécondé l’ensemble de son œuvre. The author gives (...) a brief flying over the notion of in-between as dynamics where emerge, cross and evolve the interactions between two different or opposite poles. This dynamics goes against the cleavage, so frequent in the speeches and the thoughts when one is afraid of integrating two paradoxical terms, not seeing that the in-between offers a third or a base line to escape the blocking. The author shows that this dynamics has carried and fertilized his whole work. (shrink)
