This paper discusses the suitability of using systemic thinking for teaching environmental rehabilitation to undergraduate students at Federal Universityof Viçosa. This is a predominantly agricultural sciences-based institution located in southeast Brazil. Student receptivity is discussed given concurrent campus paradigms of positivism, Marxism, and individualistic utilitarianism. Student projects using causal-loop diagrams to model degradation and land reclamation are presented. Eight archetypes common to systemic thinking are explained in reclamation contexts. Limitations of systemic thinking are discussed, including theoretical modeling problems and practical (...) teaching considerations. (shrink)

Brasil tiene una larga historia de problemas ambientales, pero la filosofía parece ir atrás de otras disciplinas que activamente consideran esta historia. Sin embargo, existe una tradición intelectual suficientemente rica para permitir el surgimiento de una filosofía ambiental genuina. Basados sobre una detallada panorámica de las discusiones pertenecientes a la reflexión ambiental y al activismo en Brasil, este trabajo revela tres campos de tensión en su historiaambiental reciente –desarrollismo militar versus activismo ambiental militante, realismo antropocéntrico versus utopía ecocéntrica, desarrollo sostenible (...) versus sostenibilidad dura–todo lo cual presupone posiciones filosóficas y representa tres correspondientes "culpables intelectuales" que deben abordarse. Entre las tendencias emergentes de la filosofía ambiental, pueden destacarse dos avenidas de pensamiento que prometen dispersar estos "culpables": pluralismo etnocultural y responsabilidad ambiental global.

Radical moral encroachment is the view that belief itself is morally evaluable, and that some moral properties of belief itself make a difference to epistemic rationality. To date, almost all proponents of radical moral encroachment hold to an asymmetry thesis: the moral encroaches on rational belief, but not on rational credence. In this paper, we argue against the asymmetry thesis; we show that, insofar as one accepts the most prominent arguments for radical moral encroachment on belief, one should likewise accept (...) radical moral encroachment on credence. We outline and reject potential attempts to establish a basis for asymmetry between the attitude types. Then, we explore the merits and demerits of the two available responses to our symmetry claim: (i) embracing moral encroachment on credence and (ii) denying moral encroachment on belief. (shrink)

Why are natural theories pre-well-ordered by consistency strength? In previous work, an approach to this question was proposed. This approach was inspired by Martin's Conjecture, one of the most prominent conjectures in recursion theory. Fixing a reasonable subsystem $T$ of arithmetic, the goal was to classify the recursive functions that are monotone with respect to the Lindenbaum algebra of $T$. According to an optimistic conjecture, roughly, every such function must be equivalent to an iterate $\mathsf{Con}_T^\alpha$ of the consistency operator ``in (...) the limit'' within the ultrafilter of sentences that are true in the standard model. In previous work the author established the first case of this optimistic conjecture; roughly, every recursive monotone function is either as weak as the identity operator in the limit or as strong as $\mathsf{Con}_T$ in the limit. Yet in this note we prove that this optimistic conjecture fails already at the next step; there are recursive monotone functions that are neither as weak as $\mathsf{Con}_T$ in the limit nor as strong as $\mathsf{Con}_T^2$ in the limit. In fact, for every $\alpha$, we produce a function that is cofinally equivalent to $\mathsf{Con}^\alpha_T$ yet cofinally equivalent to $\mathsf{Con}_T$. (shrink)

It is a well known empirical observation that natural axiomatic theories are pre-well-ordered by consistency strength. For any natural theory $T$, the next strongest natural theory is $T+\mathsf{Con}_T$. We formulate and prove a statement to the effect that the consistency operator is the weakest natural way to uniformly extend axiomatic theories.

A critical discussion of Aristotle's thoughts on moral weakness, or Akrasia, with a look at the contributions of other philosophers, such as, Socrates and Plato on this subject.

We present an analogue of Gödel’s second incompleteness theorem for systems of second-order arithmetic. Whereas Gödel showed that sufficiently strong theories that are $\Pi ^0_1$ -sound and $\Sigma ^0_1$ -definable do not prove their own $\Pi ^0_1$ -soundness, we prove that sufficiently strong theories that are $\Pi ^1_1$ -sound and $\Sigma ^1_1$ -definable do not prove their own $\Pi ^1_1$ -soundness. Our proof does not involve the construction of a self-referential sentence but rather relies on ordinal analysis.

In lieu of an abstract, here is a brief excerpt of the content:Editors’ NoteJames M. DuBois, Ana S. Iltis, and Heidi A. WalshFrom childhood, David Slakter had undergone tests and invasive procedures to monitor his nephritis. It was not a surprise when in 2015, doctors told him he needed a kidney transplant. The wife of a childhood friend was a close match and gave him one of her kidneys. Before his transplant, aerobic exercise was difficult; a few months after transplant, (...) Slakter could ride his bike, hike, and work out with a personal trainer. He no longer had to weigh food or gauge his potassium consumption, a concern for people with kidney failure. For Slakter, “life post-transplant has been a significant improvement.”Individuals or family members of those who have received an organ transplant from a living or deceased donor share their stories in this issue of Narrative Inquiry in Bioethics. The symposium is titled “Receiving the Gift of Life: Stories from Organ Transplant Recipients.” Organ transplantation can extend an individual’s life by decades. It can also greatly improve an individual’s quality of life, as was Slakter’s experience. At the same time, organ transplantation is expensive and stressful. Recipients can experience complications, including organ rejection, and there are few appealing alternatives.After her heart transplant, author Leilani R. Graham required four open-heart surgeries, ECMO, and an intra-aortic balloon pump. She experienced delirium, necrotizing pneumonia, and severe muscular atrophy that required her to re-learn how to walk. She struggled with weight gain, explosive mood swings, hair loss, and was terrified that her body would reject the new heart. For Graham, “[Transplant] was not the miracle [she] was hoping for.” Graham says she felt unprepared for and inadequately informed about what to expect after her transplant, which left her “battered, beaten, and bruised” with a 12-inch line from neck to navel and “bullet holes” up and down her torso from the chest tubes. When reflecting on her experience post-transplant, Graham says, “It wasn’t the physical trauma that hurt the most. It was that no one seemed surprised [by the aftereffects of transplant].” Seemingly no one, that is except Graham, who calls on transplant providers to “prioritize empathy.”The symposium editors are Jason T. Eberl and Tristan McIntosh. Three commentary articles, written by Macey Leigh Levan, Heather Lannon, and Vidya A. Fleetwood, Roslyn B. Mannon & Krista L. Lentine, offer important insights into the authors’ stories. The editors thank Mid-America Transplant, the UCSF Lung Transplant Program, Donor Connect, William L. Freeman, MD, MPH, MJIL, CIP, Janet Monk, and the individuals who gave anonymous donations to support the publication of this issue, an open-access VOICES edition of the symposium, and accompanying teaching guides.The research article in this issue, “‘A Shell of My Former Self’: Using Figurative Language to Promote Communication about Patient Suffering,” was written by Tyler Tate, Elizabeth Stein, and Robert A. Pearlman. The relief of suffering is a primary goal of medicine. However, the authors note that clinicians often miss or ignore suffering because they focus on the causes rather than the experience of suffering, or the subjective nature of suffering makes it difficult to discuss. The authors believe that “the key to communicating about suffering lies in finding [End Page vii] the right kind of words to describe the experience” and say that figurative language offers a promising approach. In their research, the authors performed qualitative analysis on 52 works of literature and identified 254 excerpts of figurative language with themes of non-physical or psychological suffering. The authors found 13 salient themes: brokenness, diminishment, disorientation, drowning, emptiness, imprisonment, battle, darkness, isolation, invisibility, lifelessness, punishment, and torture. The authors reiterate that developing a shared language of suffering could foster a therapeutic patient-clinician relationship and improve clinicians’ ability to recognize and address a patient’s experience of suffering.María Susana Ciruzzi wrote the first of two case studies included in this issue. “The Sword of King Solomon” addresses a tragic and difficult subject—how to navigate the situation posed by conjoined twins when “any decision will produce damage and suffering.” The case involves two infant male patients born at 37 weeks gestation as omphalo-ischiopagus conjoined twins...

Quarantine and spatial distancing measures associated with COVID-19 resulted in substantial changes to individuals’ everyday lives. Prominent among these lifestyle changes was the way in which people interacted with media—including music listening. In this repeated assessment study, we assessed Australian university students’ media use throughout early stages of the COVID-19 pandemic in Australia, and determined whether media use was related to changes in life satisfaction. Participants were asked to complete six online questionnaires, capturing pre- and during-pandemic experiences. The results indicated (...) that media use varied substantially throughout the study period, and at the within-person level, life satisfaction was positively associated with music listening and negatively associated with watching TV/videos/movies. The findings highlight the potential benefits of music listening during COVID-19 and other periods of social isolation. (shrink)

In this paper I discuss the role played by the 'categorical imperative' in the thought of Jean-Luc Nancy. I argue that, while this is a theme of major importance in Nancy's work, its overall significance is not immediately evident: on the surface, Nancy appears to be affirming the abstract exigency of the imperative while at the same time depriving it of any possible concrete force. I maintain, however, that a close reading of this theme in terms of other crucial themes (...) in Nancy's writing (namely: 'interruption' and the Heideggerian notion of 'Being-with' [Mitsein, être-avec]) reveals that Nancy's imperative does have concrete implications; indeed, it demands that we rethink the relation between responsibility and the concrete as such. Key Words: communication • community • Jacques Derrida • Martin Heidegger • imperative • Jean-Luc Nancy • responsibility. (shrink)

Though the claims they make about temporality are markedly different, Henri Bergson and Martin Heidegger agree that time is a philosophically foundational phenomenon; indeed, they agree that time is, in certain respects, the basis for all discursively representable beings. This paper focuses not so much on their theories of temporality (i.e., their respective answers to the question what is time? and their justifications for these answers) but rather on the challenges involved in talking about this phenomenon at all. Both thinkers (...) are highly sensitive to these challenges and to the problems involved in any attempt to represent time in a discursively straightforward manner. I will show that: (1) Bergson’s and Heidegger’s respective claims about time can be fully understood only if we keep this sensitivity in view and carefully note what they are—and aren’t—doing in talking about time ; and (2) what is ultimately at stake in their analyses is not just the phenomenon of time but what it means to engage in rigorous philosophical praxis.

This essay uses citational analyses to argue that most of the philosophers considered "postanalytic" - Wittgenstein, McDowell, Davidson, and Rorty - are not, in fact, genuine figures of rapprochement, since the particular essays cited, and/or the background literature that is cited, are not shared in common between the standard-bearing analytic and continental journals.

This paper is an investigation of the relationship between G\"odel's second incompleteness theorem and the well-foundedness of jump hierarchies. It follows from a classic theorem of Spector's that the relation $\{(A,B) \in \mathbb{R}^2 : \mathcal{O}^A \leq_H B\}$ is well-founded. We provide an alternative proof of this fact that uses G\"odel's second incompleteness theorem instead of the theory of admissible ordinals. We then derive a semantic version of the second incompleteness theorem, originally due to Mummert and Simpson, from this result. Finally, (...) we turn to the calculation of the ranks of reals in this well-founded relation. We prove that, for any $A\in\mathbb{R}$, if the rank of $A$ is $\alpha$, then $\omega_1^A$ is the $(1 + \alpha)^{\text{th}}$ admissible ordinal. It follows, assuming suitable large cardinal hypotheses, that, on a cone, the rank of $X$ is $\omega_1^X$. (shrink)

We examine recursive monotonic functions on the Lindenbaum algebra of EA. We prove that no such function sends every consistent φ to a sentence with deductive strength strictly between φ and (φ∧Con(φ)). We generalize this result to iterates of consistency into the effective transfinite. We then prove that for any recursive monotonic function f, if there is an iterate of Con that bounds f everywhere, then f must be somewhere equal to an iterate of Con.

It is well-known that natural axiomatic theories are well-ordered by consistency strength. However, it is possible to construct descending chains of artificial theories with respect to consistency strength. We provide an explanation of this well-orderedness phenomenon by studying a coarsening of the consistency strength order, namely, the$\Pi ^1_1$reflection strength order. We prove that there are no descending sequences of$\Pi ^1_1$sound extensions of$\mathsf {ACA}_0$in this ordering. Accordingly, we can attach a rank in this order, which we call reflection rank, to any$\Pi (...) ^1_1$sound extension of$\mathsf {ACA}_0$. We prove that for any$\Pi ^1_1$sound theoryTextending$\mathsf {ACA}_0^+$, the reflection rank ofTequals the$\Pi ^1_1$proof-theoretic ordinal ofT. We also prove that the$\Pi ^1_1$proof-theoretic ordinal of$\alpha $iterated$\Pi ^1_1$reflection is$\varepsilon _\alpha $. Finally, we use our results to provide straightforward well-foundedness proofs of ordinal notation systems based on reflection principles. (shrink)

BACKGROUND: There is a need for interdisciplinary research to better understand how pedagogical approaches in primary physical education (PE) can support the linked development of physical, cognitive and affective aspects of physical literacy and physical activity behaviours in young children. The Skill Acquisition Methods fostering Physical Literacy in Early-Physical Education (SAMPLE-PE) study aims to examine the efficacy of two different pedagogies for PE, underpinned by theories of motor learning, to foster physical literacy, especially for children living in disadvantaged areas. METHODS: (...) SAMPLE-PE will be evaluated through a cluster-randomised controlled trial targeting 5-6 year old children from schools located in areas of high deprivation in Merseyside, North-West England. Schools will be randomly allocated to one of three conditions: Linear Pedagogy, Nonlinear Pedagogy or Control. Nonlinear and Linear Pedagogy intervention primary schools will receive a PE curriculum delivered by trained coaches over 15 weeks, while control schools will follow their usual practice. Data will be collected at baseline (T0), immediately post-intervention (T1) and six months after the intervention has finished (T2). Children’s movement competence is the primary outcome in this trial. Secondary outcomes include physical activity, perceived competence, motivation, executive functions, and self-regulation. An extensive process evaluation will also examine implementation factors such as intervention context, reach, dose, fidelity and acceptability. DISCUSSION: The SAMPLE-PE project will enable better understanding surrounding how to operationalise physical literacy through enrichment of PE practices in early PE. The study will provide robust scientific evidence regarding the efficacy of underpinning PE pedagogy with theories of motor learning to promote the development of physical literacy. (shrink)
