The usual interpretation of Republic 10 takes it as Socrates’ multilevel philosophical demonstration of the untruth and dangerousness of mimesis and its required excision from a well ordered polity. Such readings miss the play of the Platonic mimesis which has within it precisely ordered antistrophes which turn its oft remarked strophes perfectly around. First, this argument, famously concluding to the unreliability of image-makers for producing knowledge begins with two images—the mirror (596e) and the painter. I will show both undercut the (...) argument they introduce. Secondly, Socrates repeats the “three removes” argument three times. Each has its own object and philosophical axis. The “bed” argument (596a-598d) concerns the ontological status of images vis-à-vis human makers and the divine idea. The bit and bridle,” 601b-601d) emphasizes the epistemological status of image-making as beneath the human maker of bridles (having correct opinion) and the human user, who knows. This second takes away the ontological distinction which was the point of the first. Thus, any human being could be in any of the three positions—user, maker, imitator. This dance might bring one to doubt the conclusion that the imitator has “neither knowledge nor right opinion” (602a). Plato leads into his concluding psychological and moral argument (602c-605c) after a third variation of the 3 removes. This last gives us the image of the flute player (601d-602) as the one who knows and so can order the flute maker. We will conclude by considering what it is this flutist could know, and given that his art is itself a mimesis, who the imitator of this imitative artist could be. Thus attention to the differences among these examples opens a defense of the arts, which reverses many of the claims made against the arts within the ostensible “Platonic” argument. (shrink)

The Republic rarely speaks of piety; yet religious concerns inform more of its treatment of poetry than readers acknowledge. A pair of tripartite rankings in Book 10 has puzzled interpreters: first the triad Form-couch-painting, then the ostensibly equivalent triad of a flute’s or bridle’s user-maker-imitator. The tripartitions work better together if one recognizes the divinity at work behind Athena’s gifts the flute and bridle. This mythic reading reveals the imitator to stand, yet again, in opposition to the gods; (...) but it also points toward an ambiguity about knowledge that Plato has forcibly excluded from his discussion.

The essay focuses on the concept of mimesis Theodor W. Adorno developed in his Aesthetic Theory. After outlining key motifs of Adorno’s critical theory so as to provide the overall intellectual context, it explains why for Adorno mimesis enacts an ethical relation to the (non-identical) other. Mimesis for Adorno, the paper suggests, counters the violence that reason inflicts on the objects of its cognition by reconstituting the latter in terms of reason’s concepts. The essay discusses mimesis also in relation to (...) other aesthetic concepts that dialectically interanimate in Adorno’s explication. It ends with very provisional thoughts on the possibilities, or lack thereof, Adorno’s Aesthetic Theory offers for the aesthetic practices of historically marginalized constituencies. (shrink)

We used a participatory approach and a rural livelihoods framework to explore the knowledge and capacity of southeast Queensland graziers to adapt to climate change. After being presented with information on climate change projections, participants identified biophysical and socio-economic opportunities and challenges to adaptation. Graziers identified key opportunities as components of resilience (incremental change), and in many cases were options that they had some knowledge of either from their own region or elsewhere in the grazing industry. The major constraint to (...) adaptation was the lack of financial capital: with low profitability of the industry and high land costs restricting their capacity to diversify and exploit economies of scale. These constraints were exacerbated by the pressure many graziers experienced from the demand for land as a result of urban expansion. While the focus of the workshop was on the impact of climate change and capacity to adapt, many of the issues raised by graziers were pressures not solely related to climate change. Adaptation needs to be considered in light of the appropriate level (resilience–transition–transformation) and spatial scale (field to region) required to tackle the issues identified. Policy needs to support good natural resource management, rural amenity, and food and fibre production close to urban population and markets in the face of urban encroachment. (shrink)

The fluted fragment is a fragment of first-order logic (without equality) in which, roughly speaking, the order of quantification of variables coincides with the order in which those variables appear as arguments of predicates. It is known that this fragment has the finite model property. We consider extensions of the fluted fragment with various numbers of transitive relations, as well as the equality predicate. In the presence of one transitive relation (together with equality), the finite model property is lost; nevertheless, (...) we show that the satisfiability and finite satisfiability problems for this extension remain decidable. We also show that the corresponding problems in the presence of two transitive relations (with equality) or three transitive relations (without equality) are undecidable, even for the two-variable sub-fragment.

We study the fluted fragment, a decidable fragment of first-order logic with an unbounded number of variables, motivated by the work of W. V. Quine. We show that the satisfiability problem for this fragment has nonelementary complexity, thus refuting an earlier published claim by W. C. Purdy that it is in NExpTime. More precisely, we consider ${\cal F}{{\cal L}^m}$, the intersection of the fluted fragment and the m-variable fragment of first-order logic, for all $m \ge 1$. We show that, for (...) $m \ge 2$, this subfragment forces $\left\lfloor {m/2} \right\rfloor$-tuply exponentially large models, and that its satisfiability problem is $\left\lfloor {m/2} \right\rfloor$-NExpTime-hard. We further establish that, for $m \ge 3$, any satisfiable ${\cal F}{{\cal L}^m}$-formula has a model of at most -tuply exponential size, whence the satisfiability problem for this fragment is in -NExpTime. Together with other, known, complexity results, this provides tight complexity bounds for ${\cal F}{{\cal L}^m}$ for all $m \le 4$. (shrink)

In the predicate calculus, variables provide a flexible indexing service which selects the actual arguments to a predicate letter from among possible arguments that precede the predicate letter (in the parse of the formula). In the process of selection, the possible arguments can be permuted, repeated (used more than once), and skipped. If this service is withheld, so that arguments must be the immediately preceding ones, taken in the order in which they occur, the formula is said to be fluted. (...) Quine showed that if a fluted formula contains only homogeneous conjunction (conjoins only subformulas of equal arity), then the satisfiability of the formula is decidable. It remained an open question whether the satisfiability of a fluted formula without this restriction is decidable. This paper answers that question. (shrink)

Richard, a sixty‐seven‐year‐old man, has been admitted to Midtown University Center for difficulty breathing. He has a significant medical history that includes pulmonary fibrosis and subsequent heart failure, and he depends on supplemental oxygen to breathe. Upon admission and after discussing his prognosis with his family and doctors, Richard decided to sign a do‐not‐resuscitate order stating that if his heart stops or he stops breathing, he does not want to undergo cardiopulmonary resuscitation or other life‐sustaining measures. On his third day (...) in the hospital, the nurse practitioner who is caring for Richard notices that his breathing is becoming more labored and that his blood pressure is steadily dropping. She thinks he requires closer observation and treatment in the cardiac intensive care unit. Dr. P, the physician in the intensive care unit at the time, Dr. P does not want to accept Richard into the CICU because of his prognosis and his DNR order. He believes that Richard should be cared for on a regular hospital floor, and that the last bed in the CICU should be held for its intended user—a patient suffering a life‐threatening heart attack who requires intensive care. Should Richard be admitted to the CICU? (shrink)

Fluted logic is the restriction of pure predicate logic to formulas in which variables play no essential role. Although fluted logic is significantly weaker than pure predicate logic, it is of interest because it seems closely to parallel natural logic, the logic that is conducted in natural language. It has been known since 1969 that if conjunction in fluted formulas is restricted to subformulas of equal arity, satisfiability is decidable. However, the decidability of sublogics lying between this restricted (homogeneous) fluted (...) logic and full predicate logic remained unknown. In 1994 it was shown that the satisfiability of fluted formulas without restriction is decidable, thus reducing the unknown region significantly. This paper further reduces the unknown region. It shows that fluted logic with the logical identity is decidable. Since the reflection functor can be defined in fluted logic with identity, it follows that fluted logic with the reflection functor also lies within the region of decidability. Relevance to natural logic is increased since the identity permits definition of singular predicates, which can represent anaphoric pronouns. (shrink)

Globalism endowed us with McDonald's, 'the world’s local bank’, English football teams without English players and an irrepressible desire for more as enough is never good enough – the blanket is always too short. Our personal world as much as our social and political realities seem to have blithely surrendered to the madness of a civilization which views anything from corporate greed and global warming to military adventures and religious fundamentalism as normal as a door banging in the wind. The (...) destructive capabilities of our age have run too far ahead of our wisdom.

Objects: To evaluate the feasibility and effectiveness of in-bed wearable elbow robot training for motor recovery in patients with early and late subacute stroke.Methods: Eleven in-patient stroke survivors received 15 sessions of training over about 4 weeks of hospital stay. During each hourly training, participants received passive stretching and active movement training with motivating games using a wearable elbow rehabilitation robot. Isometric maximum muscle strength of elbow flexors and extensors was evaluated using the robot at the beginning and end of (...) each training session. Clinical measures including Fugl-Meyer Assessment of upper extremity, Motricity Index for upper extremities, Modified Ashworth Scale were measured at baseline, after the 4-week training program, and at a 1-month follow-up. The muscle strength recovery curve over the training period was characterized as a logarithmic learning curve with three parameters.Results: At the baseline, participants had moderate to severe upper limb motor impairment {FMA-UE [median ]: 28 } and mild spasticity in elbow flexors {MAS [median ]: 0 }. After about 4 weeks of training, significant improvements were observed in FMA-UE and MI, and the improvements were sustained at the follow-up. The elbow flexors MVC significantly increased by 1.93 Nm and the elbow extensor MVC increased by 0.68 Nm. Muscle strength recovery curve showed that patients with severe upper limb motor impairment had a greater improvement rate in elbow flexor strength than those with moderate motor impairment.Conclusion: In-bed wearable elbow robotic rehabilitation is feasible and effective in improving biomechanical and clinical outcomes for early and late subacute stroke in-patients. Results from the pilot study suggested that patients with severe upper limb motor impairment may benefit more from the robot training compared to those with moderate impairment. (shrink)

The aim of this article is to explore the practical complexity of accountability in health care by focusing on a particular crisis affecting one NHS trust in the UK, that of insufficient beds to meet demand. It is presented through the eyes of five middle managers with nursing backgrounds. Although the focus is on their words, their expressions of distress and their awareness of conflict, these lead to a commentary highlighting some of the relationships between theory and practice, policy making (...) and implementation, and, in the final analysis, compulsion and choice. The managers seemed to work within four main patterns of provider accountability: public, professional, pecuniary and personal. These four Ps of accountability created incompatibilities in the accountability process, but the conclusion attempts to draw the threads together to suggest a possible way forward. In order to protect confidentiality, pseudonyms are used for the NHS trust and the interviewees, and some personal details have been disguised. (shrink)

Fluted Logic is essentially first-order predicate logic deprived of variables. The lack of variables results in reduced expressiveness. Nevertheless, many logical problems that can be stated in natural language, such as the famous Schubert's Steamroller, can be rendered in fluted logic. Further evidence of the expressiveness of fluted logic is its close relation to description logics. Already it has been shown that fluted logic is decidable and has the finite-model property. This paper shows that fluted logic has the exponential-model property (...) and that deciding satisfiability is NEXPTIME-complete. It is shown further that fluted logic is 'nice, that is, it shares with first-order predicate logic the interpolation property and model preservation properties. (shrink)

An evolutionarily informed perspective on parent-infant sleep contact challenges recommendations regarding appropriate parent-infant sleep practices based on large epidemiological studies. In this study regularly bed-sharing parents and infants participated in an in-home video study of bed-sharing behavior. Ten formula-feeding and ten breast-feeding families were filmed for 3 nights for 8 hours per night. For breast-fed infants, mother-infant orientation, sleep position, frequency of feeding, arousal, and synchronous arousal were all consistent with previous sleep-lab studies of mother-infant bed-sharing behavior, but significant differences (...) were found between formula and breast-fed infants. While breast-feeding mothers shared a bed with their infants in a characteristic manner that provided several safety benefits, formula-feeding mothers shared a bed in a more variable manner with consequences for infant safety. Paternal bed-sharing behavior introduced further variability. Epidemiological case-control studies examining bed-sharing risks and benefits do not normally control for behavioral variables that an evolutionary viewpoint would deem crucial. This study demonstrates how parental behavior affects the bed-sharing experience and indicates that cases and controls in epidemiological studies should be matched for behavioral, as well as sociodemographic, variables.

For collecting data, the researchers conducted interviews and observations. The results of the study show that Shen Wenyi's original work resulted in the invention of bamboo flutes with seven, nine, and ten holes, which are significant findings. These developments resolved issues with pitch discrepancies and broadened the range of playing techniques, influencing the flute's cultural importance and (...) musical repertoire. The study also emphasizes educational endeavors, group development, and textbook creation to safeguard and advance the flute tradition. It highlights the lasting impact and constant evolution of the Ti-Tzu ten-hole bamboo flute as a representation of cultural heritage and a source of pride in Sichuan Province. (shrink)

Most investigations of musical performance anxiety have employed quantitative methodologies. Whereas such methodologies can provide useful insights into the measurable aspects of the experience in a larger group of participants, the complexity, subtlety and individuality of the emotional experience and the importance of the individual’s interpretation of it are often overlooked. This study employed a phenomenological approach to investigate the lived, subjective experience of performance anxiety, as described in professional musicians’ narratives. Semi-structured interviews with four professional musicians (two males, two (...) females) specializing in Western classical and jazz music genres were conducted and analyzed using Interpretative Phenomenological Analysis (IPA). The analysis revealed the presence of four overarching themes: (1) Intensity of performance anxiety experience, (2) perceived effects, (3) development of coping strategies, and (4) achieving release from anxiety. Findings suggest that the lived experience of performance anxiety is multifaceted, characterized by a physical and a psychological dimension. Interpretative Phenomenological Analysis is a useful research tool that can facilitate our understanding of the subjective experience of performance anxiety (how it is felt and understood at an individual level) and can thus be useful in the development of tailor-made intervention programs for musicians.

Methods Young healthy heterosexual couples underwent sleep-lab-based polysomnography of two sleeping arrangements: individual sleep and co-sleep. Individual and dyadic sleep parameters (i.e., synchronization of sleep stages) were collected. The latter were assessed using cross-recurrence quantification analysis. Additionally, subjective sleep quality, relationship characteristics, and chronotype were monitored. Data were analyzed comparing co-sleep vs. individual sleep. Interaction effects of the sleeping arrangement with gender, chronotype, or relationship characteristics were moreover tested. Results As compared to sleeping individually, co-sleeping was associated with about 10% (...) more REM sleep, less fragmented REM sleep (p = 0.008), longer undisturbed REM fragments (p = 0.0006), and more limb movements (p = 0.007). None of the other sleep stages was significantly altered. Social support interacted with sleeping arrangement in a way that individuals with suboptimal social support showed the biggest impact of the sleeping arrangement on REM sleep. Sleep architectures were more synchronized between partners during co-sleep (p = 0.005) even if wake phases were excluded (p = 0.022). Moreover, sleep architectures are significantly coupled across a lag of ± 5min. Depth of relationship represented an additional significant main effect regarding synchronization, reflecting a positive association between the two. Neither REM sleep nor synchronization was influenced by gender, chronotype, or other relationship characteristics. Conclusion Depending on the sleeping arrangement, couple's sleep architecture and synchronization show alterations that are modified by relationship characteristics. We discuss that these alterations could be part of a self-enhancing feedback loop of REM sleep and sociality and a mechanism through which sociality prevents mental illness. (shrink)

Over the last twenty years, Bas van Fraassen has developed a “new epistemology”: an attempt to sail between Bayesianism and traditional epistemology. He calls his own alternative “voluntarism”. A constant pillar of his thought is the thought that rationality involves permission rather than obligation. The present paper aims to offer an appraisal of van Fraassen’s conception of rationality. In section 2, I review the Bayesian structural conception of rationality and argue that it has been found wanting. In sections 3 and (...) 4, I analyse van Fraassen’s voluntarism. I raise some objections about van Fraassen’s reliance on prior opinion and argue that the content of a belief matters to its rationality. In section 5, I criticise van Fraassen’s view that inference to the best explanation is incoherent. Finally, in section 6, I take on van Fraassen’s conception of rationality and show that it is too thin to fully capture rational judgement. (shrink)

The COVID-19 pandemic highlights the relevance of adequate decision making at both public health and healthcare levels. A bioethical response to the demand for medical care, supplies and access to critical care is needed. Ethically sound strategies are required for the allocation of increasingly scarce resources, such as rationing critical care beds. In this regard, it is worth mentioning the so-called ‘last bed dilemma’. In this paper, we examine this dilemma, pointing out the main criteria used to solve it and (...) argue that we cannot face these ethical issues as though they are only a dilemma. A more complex ethical view regarding the care of COVID-19 patients that is focused on proportional and ordinary treatments is required. Furthermore, discussions and forward planning are essential because deliberation becomes extremely complex during an emergency and the physicians’ sense of responsibility may be increased if it is faced only as a moral dilemma.

This article examines the spatialization of sleep in Victorian Britain across a range of institutions, including homes and dormitories. It situates the emergence of modern sleeping space at the intersection of two key narratives regarding the history of the body: Elias's `civilising process' and Foucault's account of the realization of a `disciplinary society'. Beginning in the early modern period, sleeping bodies were gradually accorded their own space set apart from others, and by the end of the 19th century the individual (...) bed was regarded as an essential ingredient of civilized society. However, the evolution of modern sleeping space was only in part informed by ideas of privacy and civility: it was also animated by ideas concerning the functioning of `normal' bodies and minds, the governmental agency of space and the moral integrity of nuclear families. Furthermore, the bed remained a highly problematic, indeterminate space, facilitating deviant as much as civilized behaviour, and giving rise to all manner of pathologies, perversities and phobias. In this respect, the history of sleeping space also sheds light on the reciprocities of rule and resistance, pleasure and power, which at once constitute and imperil the integrity of the modern body.

This paper examines the marital bed through existential themes of spatial, temporal, corporeal and relational experience. It is a collaborative effort in that it relates anecdotes contributed by twelve people who each described – in writing, in interviews and in conversation – very personal moments of life in the “marital bed”. Through other eyes, one sees that what seemed unique has echoes of a shared experience. The everyday noises and movements, the negotiations, even the sorrows of that particular place, are (...) so familiar that, in recognising them as true to one’s own experience, one wonders, “Is it like this for others too?” What is presented here is the culmination of researching a phenomenon by trying to capture it in writing and rewriting, in order to give form to the truth in an experience, while knowing that, by writing it, the real truth becomes limited. Phenomenological writing becomes a conversation which is at once both intimate and universal. The marital tales speak to a specific journey, but, as when one recounts details of any special trip – say Paris, for example – the listeners are drawn inward to their own experience. Personal remembrance enmeshes with public exposure so that the collective sighs, “Ah yes, Paris.” And therefore we know some small fragment of an abandoned bed as truly as we know the family bed.

The influence of William James on Ludwig Wittgenstein has been widely studied, as well as the criticism that the latter addresses to the former, but one aspect that has only rarely been focused on is the two philosophers’ use of the image of the flux, stream, or river. The analysis of some notes belonging to Wittgenstein’s Nachlass support the possibility of a comparison between James’ stream of thought, as outlined in the Principles of Psychology, and Wittgenstein’s river-bed of thoughts, presented (...) in On Certainty. After an introduction which offers a general frame for the following work, the first section of the paper examines all the Nachlass entries that directly mention James’ stream. Section 2 focuses on two remarks in which Wittgenstein explicitly criticizes James’ concept and implicitly anticipates his own way of dealing with this matter. These remarks, belonging to Manuscripts 165 and 129, both dating 1944, have not been published in any of Wittgenstein’s edited books, nor is it possible to find the same argument elsewhere. Wittgenstein’s critique concerns James’ lack of distinction between what is grammatical, or a priori, and what is empirical, or a posteriori, a distinction which the image of the stream should have suggested: a stream flows in a stream-bed and within banks. This is exactly the meaning that Wittgenstein’s own metaphor of the river-bed of thoughts is intended to convey. Section 3 analyses James’ concept of the stream and its corollaries, in order to clarify whether Wittgenstein’s critique is justified or not. James in effect draws a separation between a priori and a posteriori, but this separation is conceived from within the framework of empirical science. This analysis leads to the theme of the relations among science, philosophy and metaphysics, which is the subject of section 4. The conclusion is that Wittgenstein did appreciate James for his intuitions and for the power of his imagination: in a sense he even developed them; but he could not agree on the explicit formulation of his ideas.

This paper presents part of a larger study of contemporary nursing practice and the rationalisation of hospital length of stay. Informed by Michel Foucault's work on governmentality, length of hospital stay and the re-engineering of surgical services are examined, not in terms of numerical representations of hospital use, but as part of social and political processes through which certain concepts are made susceptible to measurement and practices are organised. Using data generated through fieldwork in a hospital surgical division this analysis (...) offers understandings of how social practices around length of hospital stay are translated and how they pattern contemporary hospital nursing practice. Nursing practice is explored through the reconstitution of hospital beds and the demands of local administration of hospital length of stay. (shrink)
