This study is divided into two main parts: exposition of the main themes of Process and Reality and criticism. The exposition is organized around the twin motifs of "freedom" and "condition." The former refers to such notions as mental pole, conceptual feelings, final causation, novelty, flux, and subjective aim. The latter refers to things like physical pole, physical feelings, efficient causation, conformation of feeling, permanence, and objectification. The exposition, quite naturally and justifiably, is laid out with an eye to the (...) criticisms which will follow it. The points of criticism all relate to the general problem of the tension between the factor of freedom and the factor of condition. For example, the author tries to resolve the incompatibility between the indivisible unity of an actual occasion and the fact that it undergoes successive modifications of its subjective aim. He points out the difficulty in maintaining the doctrine of freedom when the modification of the subjective aim is effected by determinate elements. Pols feels that Whitehead's system places the seat of power in the eternal objects. It is they that are really effecting the difference between real and general potentiality. It is this special status of the eternal objects that, for Pols, constitutes "The Platonism of Whitehead." In general, the book is a tough minded refusal to allow Whitehead to eat and still have his metaphysical cake.--S. 0. H. (shrink)

Background Residual dried blood spots (rDBS) from newborn screening programmes represent a valuable resource for medical research, from basic sciences, through clinical to public health. In Hong Kong, there is no legislation for biobanking. Parents’ view on the retention and use of residual newborn blood samples could be cultural-specific and is important to consider for biobanking of rDBS. Objective To study the views and concerns on long-term storage and secondary use of rDBS from newborn screening programmes among Hong Kong Chinese (...) parents. Methods A mixed-method approach was used to study the views and concerns on long-term storage and secondary use of rDBS from newborn screening programmes among Hong Kong Chinese parents of children 0–3 years or expecting parents through focus groups (8 groups; 33 participants) and a survey (n = 1012, 85% mothers) designed with insights obtained from the focus groups. We used framework analysis to summarise the themes as supportive factors, concerns and critical arguments for retention and secondary use of rDBS from focus group discussion. We used multiple logistic regression to assess factors associated with support for retention and secondary use of rDBS in the survey. Results Both in focus groups and survey, majority of parents were not aware of the potential secondary use of rDBS. Overall secondary use of rDBS in medical research was well accepted by a large proportion of Hong Kong parents, even if all potential future research could not be specified in a broad consent. However parents were concerned about potential risks of biobanking rDBS including leaking of data and mis-use of genetic information. Parents wanted to be asked for permission before rDBS are stored and mainly did not accept an “opt-out” approach. The survey showed that parents born in mainland China, compared to Hong Kong born parents, had lower awareness of newborn screening but higher support in biobanking rDBS. Higher education was associated with support in rDBS biobanking only among fathers. Conclusion Long-term storage and secondary use of rDBS from newborn screening for biomedical research and a broad consent for biobanking of rDBS are generally acceptable to Hong Kong parents given their autonomy is respected and their privacy is protected, highlighting the importance of an accountable governance and a transparent access policy for rDBS biobanks.

Objective: To determine whether a moral reasoning exercise can improve response quality to surveys of healthcare priorities Methods: A randomised internet survey focussing on patient age in healthcare allocation was repeated twice. From 2574 internet panel members from the USA and Canada, 2020 (79%) completed the baseline survey and 1247 (62%) completed the follow-up. We elicited respondent preferences for age via five allocation scenarios. In each scenario, a hypothetical health planner made a decision to fund one of two programmes identical (...) except for average patient age (35 vs 65 years). Half of the respondents (intervention group) were randomly assigned to receive an additional moral reasoning exercise. Responses were elicited again 7 weeks later. Numerical scores ranging from –5 (strongest preference for younger patients) to +5 (strongest preference for older patients); 0 indicates no age preference. Response quality was assessed by propensity to choose extreme or neutral values, internal consistency, temporal stability and appeal to prejudicial factors. Results: With the exception of a scenario offering palliative care, respondents preferred offering scarce resources to younger patients in all clinical contexts. This preference for younger patients was weaker in the intervention group. Indicators of response quality favoured the intervention group. Conclusions: Although people generally prefer allocating scarce resources to young patients over older ones, these preferences are significantly reduced when participants are encouraged to reflect carefully on a wide range of moral principles. A moral reasoning exercise is a promising strategy to improve response quality to surveys of healthcare priorities. (shrink)

“Rethinking moral status” provides a forum for philosophers to reason on the usual presuppositions and intuitions about moral status, especially now with new scientific advances like non-human chimeras, cyborgs, human brain organoids, and post-human minds. There are a number of ways we could respond to the new challenges these technological developments raise: this volume explores such responses and tries to clarify the concept of moral status itself.

The energy-spectrum of two point-like particles interacting in a 3-D isotropic Harmonic Oscillator (H.O.) trap is related to the free scattering phase-shifts \(\delta \) of the particles by a formula first published by Busch et al. It is here used to find an expression for the shift of the energy levels, caused by the interaction, rather than the perturbed spectrum itself. In the limit of high energy (large quantum number \(n\) of the H.O.) this shift (in H.O. units) is shown (...) to be given by \(\Delta =-2\frac{\delta }{\pi }\) , also exact in the limit of infinite scattering length ( \(\delta =\pm \frac{\pi }{2}\) ) in which case \(\Delta =\mp 1\) . Numerical investigation shows that this expression otherwise differs from the exact result of Busch et al., by less than \(\frac{1}{2}\,\%\) except for \(n=0\) when it can be as large as \(\approx \) 2.5 %. This result for the energy-shift is well known from another exactly solvable model, namely that of two particles interacting in a spherical infinite square-well trap (or box) of radius \(R\) in the limit \(R\rightarrow \infty \) , and/or in the limit of large energy. It is in solid state physics referred to as Fumi’s theorem. It can be (and has been) used in (infinite) nuclear matter calculations to calculate the two-body effective interaction in situations where in-medium effects can be neglected. It is in this context referred to as the phase-shift approximation a term also used throughout this report. (shrink)

Background To describe the preferences for disclosure of individual biomarker results among mothers participating in a longitudinal birth cohort. Methods We surveyed 343 mothers that participated in the Health Outcomes and Measures of the Environment Study about their biomarker disclosure preferences. Participants were told that the study was measuring pesticide metabolites in their biological specimens, and that the health effects of these low levels of exposure are unknown. Participants were asked whether they wanted to receive their results and their child's (...) results. In addition, they were asked about their preferred method (letter vs in person) and format (more complex vs less complex) for disclosure of results. Results Almost all of the study participants wanted to receive their individual results (340/343) as well as their child's results (342/343). However, preferences for receiving results differed by education level. Mothers with less than a college degree preferred in-person disclosure of results more often than mothers with some college education or a college degree (34.3% vs 17.4% vs 7.9%, p<0.001). Similarly, mothers with less than a college education preferred a less complex disclosure format than mothers with some college education or a college degree (59.7% vs 79.1% vs 86.3%, p<0.0001). Conclusion While almost all study participants preferred to receive results of their individual biomarker tests, level of education was a key factor in predicting preferences for disclosure of biomarker results. To ensure effective communication of this information, disclosure of biomarker results should be tailored to the education level of the study participants. (shrink)

This paper consists primarily of a survey of results of Harvey Friedman about some proof-theoretic aspects of various forms of Kruskal's tree theorem, and in particular the connection with the ordinal Γ0. We also include a fairly extensive treatment of normal functions on the countable ordinals, and we give a glimpse of Verlen hierarchies, some subsystems of second-order logic, slow-growing and fast-growing hierarchies including Girard's result, and Goodstein sequences. The central theme of this paper is a powerful theorem due to (...) Kruskal, the ‘tree theorem’, as well as a ‘finite miniaturization’ of Kruskal's theorem due to Harvey Friedman. These versions of Kruskal's theorem are remarkable from a proof-theoretic point of view because they are not provable in relatively strong logical systems. They are examples of so-called ‘natural independence phenomena’, which are considered by most logicians as more natural than the metamathematical incompleteness results first discovered by Gödel. Kruskal's tree theorem also plays a fundamental role in computer science, because it is one of the main tools for showing that certain orderings on trees are well founded. These orderings play a crucial role in proving the termination of systems of rewrite rules and the correctness of Knuth-Bendix completion procedures. There is also a close connection between a certain infinite countable ordinal called Γo and Kruskal's theorem. Previous definitions of the function involved in this connection are known to be incorrect, in that, the function is not monotonic. We offer a repaired definition of this function, and explore briefly the consequences of its existence. (shrink)

Objective To determine the attitudes of Egyptian patients regarding their participation in research and with the collection, storage and future use of blood samples for research purposes. Design Cross-sectional survey. Study population Adult Egyptian patients (n=600) at rural and urban hospitals and clinics. Results Less than half of the study population (44.3%) felt that informed consent forms should provide research participants the option to have their blood samples stored for future research. Of these participants, 39.9% thought that consent forms should (...) include the option that future research be restricted to the illness being studied. A slight majority (66.2%) would donate their samples for future genetic research. Respondents were more favourable towards having their blood samples exported to other Arab countries (62.0%) compared with countries in Europe (41.8%, p<0.001) and to the USA (37.2%, p<0.001). Conclusions This study shows that many individuals do not favour the donation of a blood sample for future research. Of those who do approve of such future research, many favour a consent model that includes an option restricting the future research to the illness being studied. Also, many Egyptians were hesitant to have their blood samples donated for genetic research or exported out of the Arab region to the USA and European countries. Further qualitative research should be performed to determine the underlying reasons for many of our results. (shrink)

Thomas Pradeu’s The Limits of the Self provides a precise account of biological identity developed from the central concepts of immunology. Yet the central concepts most relevant to this task are themselves deemed inadequate, suffering from ambiguity and imprecision. Pradeu seeks to remedy this by proposing a new guiding theory for immunology, the continuity theory. From this, an account of biological identity is provided in terms of uniqueness and individuality, ultimately leading to a defense of the heterogeneous organism as expressing (...) the highest degree of individuality.

According to the Einstein-Mayer theory of the Riemanniann space-time with Einstein-Cartan teleparallelism, the local Lorentz invariance is broken by the gravitational field defining Machian reference systems. This breaking of symmetry implies the occurrence of “hidden matter” in the Einstein equations of gravity. The hidden matter is described by the non-Lorentz-invariant energy-momentum tensor $\hat \Theta _{ik}$ satisfying the relation $\hat \Theta _{i;k}^k = 0$ . The tensor $\hat \Theta _{ik}$ is formed from the Einstein-Cartan torsion field given by the anholonomy objects, (...) FAik=2hA[i,k], and appears together with Hilbert’s energy-momentum tensor T* ik and Poincaré’s pressure λgik on the right-hand side of Einstein’s equations so that one has $$R_{ik} - (1/2)g_{ik} R = - \kappa T*_{ik} - \lambda g_{ik} - \hat \Theta _{ik}$$ According to this theory, in the universe and in cosmic systems one must excep “invisible masses” described by the Poincaré and Einstein-Cartan terms to exist. The torsion field FAik makes the space-time a Machian universe; it is of the same nature as the “weak interacting matter” discussed in astrophysics. (shrink)

§0. Introduction. In [16], Barwise described his graduate study at Stanford. He told of his interactions with Kreisel and Scott, and said how he chose Feferman as his advisor. He began working on admissible fragments of infinitary logic after reading and giving seminar talks on two Ph.D. theses which had recently been completed: that of Lopez-Escobar, at Berkeley, on infinitary logic [46], and that of Platek [58], at Stanford, on admissible sets.Barwise's work on infinitary logic and admissible sets is described (...) in his thesis [4], the book [13], and papers [5]—[16]. We do not try to give a systematic review of these papers. Instead, our goal is to give a coherent introduction to infinitary logic and admissible sets. We describe results of Barwise, of course, because he did so much. In addition, we mention some more recent work, to indicate the current importance of Barwise's ideas. Many of the central results are stated without proof, but occasionally we sketch a proof, to indicate how the ideas fit together.Chapters 1 and 2 describe infinitary logic and admissible sets at the time Barwise began his work, circa 1965. From Chapter 3 on, we survey the developments that took place after Barwise appeared on the scene.§1. Background on infinitary logic. In this chapter, we describe the situation in infinitary logic at the time that Barwise began his work. We need some terminology. By a vocabulary, we mean a set L of constant symbols, and relation and operation symbols with finitely many argument places. As usual, by an L-structureM, we mean a universe set M with an interpretation for each symbol of L. (shrink)

Although various scholars underscore the importance of innovating responsibly in view of today's societal challenges, less attention has been paid to the entrepreneurial skillset, that is, the range of individual skills and organizational capabilities, that innovation-based organizations mobilize to deliver new responsible products and services. This paper thus explores the relationships between the entrepreneurial skillsets of 16 Canadian and Brazilian for-profit and not-for-profit organizations producing Responsible Innovations in Health (RIH) and their degree of responsibility. Our mixed methods study includes interviews (...) with entrepreneurs (n = 23) and fieldnotes as well as quantitative results from the RIH Assessment Tool. Our findings identify four skillset orientations—Technical, Technical + Business, Social, and Social + Business—that not only reflect (co)founders' training and entrepreneurial motivations but also a proclivity toward the consolidation of either “Technical” or “Social” skills and capabilities. Such consolidation is made possible by recruiting high-level executives with diverse backgrounds or by tapping on external knowledge sources (e.g., boards of directors, incubators, or volunteers). As five enterprises had no formal business skills, patterns associated to their overall RIH score (ranging from 1 to 5) reveal intriguing results. Organizations with a Social + Business skillset have a slightly lower RIH score (4.1) than those with a Social skillet (4.4) and those with a Technical + Business skillset have a slightly higher score (3.5) than those with a Technical skillset (3.0). The presence of business skills thus appears to mediate the relationship between entrepreneurial skillsets and the degree of responsibility, which may be linked to the distinct roles of ordinary (“doing things right”) and dynamic capabilities (“doing the right things”). These exploratory findings have scholarly and practical implications. First, the tensions and synergies characterizing responsible value creation should be approached by examining the complementary skills and capabilities that need to be assembled and consolidated. Second, the eight cases with a Social + Business skillset clarify the unique capabilities needed to produce highly responsible health innovations. Third, entrepreneurs with a scientific or engineering background should recognize that a Technical skillset is not enough. Fourth, recognizing that “falling in love with the cause” of RIH is not sufficient, investors and boards of directors should adequately support responsible entrepreneurs towards the proper orchestration of skills and capabilities that can reconcile economic and social goals.

Recall that B is PA relative to A if B computes a member of every nonempty $\Pi ^0_1(A)$ class. This two-place relation is invariant under Turing equivalence and so can be thought of as a binary relation on Turing degrees. Miller and Soskova [23] introduced the notion of a $\Pi ^0_1$ class relative to an enumeration oracle A, which they called a $\Pi ^0_1{\left \langle {A}\right \rangle }$ class. We study the induced extension of the relation B is PA relative (...) to A to enumeration oracles and hence enumeration degrees. We isolate several classes of enumeration degrees based on their behavior with respect to this relation: the PA bounded degrees, the degrees that have a universal class, the low for PA degrees, and the ${\left \langle {\text {self}\kern1pt}\right \rangle }$ -PA degrees. We study the relationship between these classes and other known classes of enumeration degrees. We also investigate a group of classes of enumeration degrees that were introduced by Kalimullin and Puzarenko [14] based on properties that are commonly studied in descriptive set theory. As part of this investigation, we give characterizations of three of their classes in terms of a special sub-collection of relativized $\Pi ^0_1$ classes—the separating classes. These three can then be seen to be direct analogues of three of our classes. We completely determine the relative position of all classes in question. (shrink)

Background Informed consent confers upon participants the right to decline or accept participation in a study in equal measure. Consent declines can be used as a potential metric to assess the adequacy of the informed consent process. Limited literature is available on the reporting of consent declines in Clinical Research. We evaluated randomized controlled trials published in three high-impact factor journals for consent declines (four-year period) to assess the extent of exertion of autonomy by research participants. Methods CONSORT flow charts (...) in RCTs published in New England Journal of Medicine (NEJM), The Lancet and Journal of the American Medical Association (JAMA) between 2012 and 2015 were evaluated. The total and per journal proportion of RCTs reporting consent declines was calculated. Percentage of consent declines was also compared based on number of centers (single centric vs. multicentric) and type of setting (developed vs. developing). Between-groups analysis was done using Chi Square, Chi Square for trend and a Crude odds ratio [95% C.I] (cOR) were calculated. Results Only 3.7% (1103/29,825) of the published articles were RCTs. Of the 1103 RCTs, only 532 (48.2%) reported consent declines. JAMA had the highest RCTs reporting consent declines (171/267.64%), the Lancet [129,150/781,924, 16.5%] had the most participants declining consent. Difference was significant using Chi square for linear trend [ p < 0.00001]. Consent decline rate was higher in developed countries relative to developing countries [cOR(95% C.I): 2.27(2.23,2.32), p < 0.000001] and in single centric versus multicentric studies [cOR (95% C.I): 3.63(3.56,3.71), p < 0.0000001]. Conclusion Both authors and journal editors need to ensure better reporting of consent declines. (shrink)

Context. The identification of the sources that reionized the Universe and their specific contribution to this process are key missing pieces of our knowledge of the early Universe. Faint star-forming galaxies may be the main contributors to the ionizing photon budget during the epoch of reionization, but their escaping photons cannot be detected directly due to inter-galactic medium opacity. Hence, it is essential to characterize the properties of faint galaxies with significant Lyman continuum photon leakage up to z 4 to (...) define indirect indicators allowing analogues to be found at the highest redshift. Aims. Long gamma-ray bursts explode typically in star-forming regions of faint, star-forming galaxies. Through LGRB afterglow spectroscopy it is possible to detect directly LyC photons. Our aim is to use LGRBs as tools to study LyC leakage from faint, star-forming galaxies at high redshift. Methods. Here we present the observations of LyC emission in the afterglow spectra of GRB 191004B at z = 3:5055, together with those of the other two previously known LyC-emitting LGRB, to determine their LyC escape fraction and compare their properties. Results. From the afterglow spectrum of GRB 191004B we determine a neutral hydrogen column density at the LGRB redshift of og =17:2 0:15, and negligible extinction. The only metal absorption lines detected are C iv and Si iv. In contrast to GRB 050908 and GRB 060607A, the host galaxy of GRB 191004B displays significant Ly emission. From its Ly emission and the non-detection of Balmer emission lines we constrain its star-formation rate to 1 SFR 4:7 M yr. 1. We fit the Ly emission with a shell model and find parameters values consistent with the observed ones. The absolute LyC escape fractions we find for GRB 191004B, GRB 050908 and GRB 060607A are of 0:35+0:10.0:11, 0:08+0:05.0:04 and :20+0:05.0:05, respectively. We compare the LyC escape fraction of LGRBs to the values of other LyC emitters found from the literature, showing that LGRB afterglows can be powerful tools to study LyC escape for faint high-redshift star-forming galaxies. Indeed we could push LyC leakage studies to much higher absolute magnitudes. The host galaxies of the three LGRB presented here have all M1600 >.19:5 mag, with the GRB 060607A host at M1600 >.16 mag. LGRB hosts may therefore be particularly suitable for exploring the ionizing escape fraction in galaxies that are too faint or distant for conventional techniques. Furthermore the time investment is very small compared to galaxy studies. (shrink)

The Einstein equations can be written as Fierz-Pauli equations with self-interaction, $W\gamma _{ik} = - G_{ik} + \tfrac{1}{2}g_{ik} g^{mn} G_{mn} - k(T_{ik} - \tfrac{1}{2}g_{ik} g^{mn} T_{mn} )$ together with the covariant Hilbert-gauge condition, $(\gamma _i^h - \tfrac{1}{2}\delta _i^k g^{mn} \gamma _{mn} )_{;k} = 0$ where W denotes the covariant wave operator and G ik the Einstein tensor of the metric g ik collecting all nonlinear terms of Einstein's equations. As is known, there do not, however, exist plane-wave solutions γ ik(z)with (...) g ik Z,i Z,k=0of these equations such that what is essential to the introduction of gravitons is not satisfied in general relativity. This nonexistence corresponds with the uncertainty relation,Δp(Δg*)2(Δx)3≥h hG/ c 3 concerning the total nonlinear gravitational field g *ik =g k +γ k. (shrink)

Given the generic canonical probability in phase φ=exp[β(Ψ-H)], contact is traditionally made with phenomenological thermodynamics by comparing the identity δ〈φ〉=0 with the relationTδS=δU+δW, δ indicating an arbitrary infinitesimal variation of the thermodynamic coordinates and angular brackets ensemble means. This paper is concerned with the inverse problem of finding both the generic form of the phase functionw such thatS=〈w〉 and the explicit form φ=αexp[(F-H)/kT] of the canonical distribution on the basis of the requirement that the consequences of the phenomenological laws must (...) be safeguarded, i.e., the relations between the quantities which are their concomitants must also be satisfied by their statistical representatives. Given the generic statistical formalism and specifically thatU=〈H〉, δW=−〈δH〉, the problem is soluble, granted the following generic assumption: “the statistical representative of the entropy is the ensemble mean of a function which depends upon the phase through φ alone.”.

We thank Leo Lam and Taylor Nichols for their response1 to our paper ‘COVID-19 vaccine boosters for young adults: a risk–benefit assessment and ethical analysis of mandate policies at universities’.2 In our paper, we demonstrate that the risk–benefit calculus to mandate boosters for young adults aged 18–29 is a net risk intervention. The authors assert that we have made three inappropriate comparisons of benefits versus risks of the mRNA vaccine booster dose in this age group. We provide our response to (...) each below. We erred on the side of overestimating benefits of the booster dose against severe COVID-19 in this age group and still found net harms to outweigh net benefits. The conclusion of our paper holds, and university booster mandates for young people were—and remain—unethical. For the first comparison, we weighed predicted hospitalisations prevented by one booster dose of BNT162b2 with vaccine-associated SAEs from the manufacturer’s randomised trial (3/5055).3 We found that the rate of expected SAEs would outweigh the benefits of the booster against hospitalisation by at least 18-fold. Lam and Nichols suggest that this was an inappropriate comparison, as not all SAEs result in hospitalisation. However, the definition of SAE as used in the trial included death, hospitalisation, disability, permanent damage, life-threatening event or condition, which required medical or surgical intervention to prevent a serious outcome.4 While all comparisons include some degree of incommensurability, comparing these SAEs with hospitalisations prevented by the booster is more reasonable than Lam and Nichols’ suggestion of comparing SAEs to infections prevented. The COVID-19 infection hospitalisation risk in this age group was <0.5% (or <1/200)5 even prior to widespread immunity, thus comparing SAEs to infection risk is entirely inappropriate. Furthermore, a booster dose will only offer transient (if any) protection against infection6 and cumulative infection rates …. (shrink)

BackgroundThe COVID-19 pandemic has created ethical challenges for intensive care unit (ICU) professionals, potentially causing moral distress. This study explored the levels and causes of moral distress and the ethical climate in Dutch ICUs during COVID-19.MethodsAn extended version of the Measurement of Moral Distress for Healthcare Professionals (MMD-HP) and Ethical Decision Making Climate Questionnaire (EDMCQ) were online distributed among all 84 ICUs. Moral distress scores in nurses and intensivists were compared with the historical control group one year before COVID-19. ResultsThree (...) hundred forty-five nurses (70.7%), 40 intensivists (8.2%), and 103 supporting staff (21.1%) completed the survey. Moral distress levels were higher for nurses than supporting staff. Moral distress levels in intensivists did not differ significantly from those of nurses and supporting staff. “Inadequate emotional support for patients and their families” was the highest-ranked cause of moral distress for all groups of professionals. Of all factors, all professions rated the ethical climate most positively regarding the culture of mutual respect, ethical awareness and support. “Culture of not avoiding end-of-life-decisions” and “Self-reflective and empowering leadership” received the lowest mean scores. Moral distress scores during COVID-19 were significantly lower for ICU nurses (p < 0.001) and intensivists (p < 0.05) compared to one year prior.ConclusionLevels and causes of moral distress vary between ICU professionals and differ from the historical control group. Targeted interventions that address moral distress during a crisis are desirable to improve the mental health and retention of ICU professionals and the quality of patient care. (shrink)

Tradition II Hermeneutics, Ethics, and the Dispensation of the Good Stephen H. Watson Examines concepts of tradition in 20th-century Continental philosophy. In Tradition II, Stephen H. Watson engages post-Kantian Continental philosophy in his continuing investigation into the concept of tradition which he began in his work, Tradition. According to Watson, the problem of tradition became explicit in 20th-century philosophy, and is especially apparent in the work of Heidegger, Gadamer, Husserl, Benjamin, Adorno, Levinas, Kristeva, and Derrida, among others. By formulating a (...) series of dialogues between these philosophers and their predecessors, Watson articulates the issues and concerns surrounding tradition and traditionality. Taking on topics such as the hermeneutics of the self, the rationality of tradition, the pluralistic nature of historical interpretation, and the question of the "other," Watson emphasizes the importance of classical accounts of ethical and political discourse for contemporary philosophy and today’s multicultural world. Watson extends his analysis of tradition to include the problems of meaning and narrative and the nature of the self. He also considers the meaning of the Good and how Good is dispensed in the world. By questioning past philosophical narratives and their influence on modern and postmodern philosophy, Watson brings fresh perspective to the complex meanings of tradition for a pluralistic world. Stephen H. Watson is Professor of Philosophy and Chair of the Philosophy Department at the University of Notre Dame.

The effects of the vacuum electromagnetic fluctuations and the radiation reaction fields on the time development of a simple microscopic system are identified using a new mathematical method. This is done by studying a charged mechanical oscillator (frequency Ω 0)within the realm of stochastic electrodynamics, where the vacuum plays the role of an energy reservoir. According to our approach, which may be regarded as a simple mathematical exercise, we show how the oscillator Liouville equation is transformed into a Schrödinger-like stochastic (...) equation with a free parameter h′ with dimensions of action.

Despite their status as high-income food producing nations, children and their caregivers, both in the United States (U.S.) and Australia can experience food insecurity. Nutrition researchers formed a joint U.S.-Australia collaboration to help advance food security for households with young children aged 0–5 years. This study investigated food insecurity from the perspective of caregivers, especially their perceptions of the impact of food insecurity on their own childhood, their current life, and for the children in their care. Semi-structured interviews were conducted (...) from July to September 2020 during the COVID-19 pandemic. Participants were recruited in Omaha, Nebraska, U.S. (_n_ = 19) and Melbourne, Victoria, Australia (_n_ = 22), during periods of stay-at-home public health orders. These two case study sites enabled an exploration of some universal, and some context-specific, social, economic, and health conditions that buffer, or exacerbate, food insecurity for families in these neo-liberal political settings. An inductive thematic analysis was conducted and established six themes:_growing up poor_, _lessons learned_,_ feeding a family amidst a pandemic_,_ caregiver coping strategies_, _food security in the early years_ and _protecting (young) children_. Perspectives on local anti-hunger strategies were organized to outline participant’s preferred solutions. Household food insecurity is conceptualized in public policy in the U.S. and Australia as a short-term crisis for people, justifying austere, time-limited and patchwork solutions. A narrative of caregivers’ lived experience of food insecurity suggests that it is inter-generational, and exacerbated by a food system shock (i.e., COVID-19). These findings from two varying cities and nations offer a different conceptualization of the timespan and nature of the phenomenon of food insecurity, challenging a dominant policy narrative and highlighting the inadequacy of current so-called solutions.
