The mental and emotional dimensions of climate change are increasingly concerning as extreme events become more frequent and severe, ecosystem destruction advances, and people become more aware of climate impacts and injustices. Research on climate emotions has rapidly advanced over the last decade with growing evidence illustrating that climate emotions can impact health, shape climate action, and ought to be considered in climate change communication, education, and engagement. This paper explores, describes, and discusses climate emotions in the context of Canada’s (...) Provincial North: a vast region characterized by a vulnerability to climate change, remoteness, political marginalization, diverse Indigenous populations, and economies/livelihoods tied to resource extraction. Using postal survey data collected in two Provincial North communities, we aim to describe climate emotions experienced in the context of Canada’s Provincial North, including relationships among specific emotions; and examine if socio-demographic variables show a relationship with climate emotions. Results show high levels of emotional response to climate change overall, with worry and frustration as those emotions reported by the highest percentage of participants. We also find significant difference in climate emotions between men and women. A methodological result was noted in the usefulness of the Climate Emotion Scale, which showed high reliability and high inter-item correlation. A notable limitation of our data is its’ underrepresentation of Indigenous peoples. The findings contribute to a greater understanding of climate emotions with relevance to similar settings characterized by marginalization, vulnerability to climate change, urban islands within vast rural and remote landscapes, and economies and social identities tied to resource extraction. We discuss our findings in relation to the literature and outline future research directions and implications. (shrink)

There is a strong perception in the social sciences that the welfare state and socialism differ qualitatively rather than by degree. This perception holds that the welfare state is fundamentally incapable, in any incarnation, of realizing the social aspirations of socialism, and that socialism is likewise destructive of welfare state ideals. As a result of such thinking, the marginal, intersectional world that does exist between the welfare state and socialism becomes hidden from view. This consequence is of particular concern to (...) theorists in search of a more egalitarian society than markets, on their own, can produce. This paper analyses the welfare state/socialism dichotomy in the works of Marx and J.S. Mill, looking to see whether it was plausible at its point of historical origin. The conclusion is that it was not; that the dichotomy only seemed to make sense because neither theorist employed a language capable of capturing the complexity of the social relations in question.

BackgroundOther Specified Feeding and Eating Disorders are characterized by less frequent symptoms or symptoms that do not meet full criteria for another eating disorder. Despite its high prevalence, limited research has examined differences in severity and treatment outcome among patients with OSFED compared to threshold EDs [Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorder ]. The purpose of the current study was to examine differences in clinical presentation and treatment outcome between a heterogenous group of patients with OSFED or threshold (...) EDs.MethodPatients with threshold EDs or OSFED presenting for eating disorder treatment completed self-report questionnaires at intake and discharge to assess eating disorder symptoms, depression symptoms, impairment, and self-esteem.ResultsAt intake, OSFED patients showed lower eating concerns compared to patients with BN, but similar levels compared to AN and BED. The OSFED group showed higher restraint symptoms compared to BED, and similar restraint to AN and BN. Global symptoms as well as shape and weight concerns were similar between OSFED and threshold ED groups. There were no differences between diagnostic groups in self-esteem, depression scores, or symptom change from intake to discharge.DiscussionOur findings suggest that individuals with OSFED showed largely similar ED psychopathology and similar decreases in symptoms across treatment as individuals diagnosed with threshold EDs. Taken together, findings challenge the idea that OSFED is less severe and more resistant to treatment than threshold EDs. (shrink)

Anorexia Nervosa (AN) is widely considered to be a bodily disorder accompanied by unrealistic perceptions about one’s own body. Some researchers thus have wondered whether deficits in interoception, a conscious or non-conscious sense of one’s own body, could be a primary cause of AN. In this paper, we make the case that rather than interoception being a primary cause, deficits in interoception may occur as by-products of emotions that arise upstream in the pathogenesis of AN and interact with feelings of (...) a loss of self-control. We consider interoception, emotion, and self-control as a dynamical triad involved in the explanation of AN, with emotions as the central aspect of their interactions. We begin with a critical analysis of recent empirical literature on AN and differentiate three types of interoceptive processes. We then consider the role of self-control in AN. We go on to evaluate recent empirical and philosophical work on the role of emotions in AN and assess their importance in both interoception and self-control dynamics. We develop a testable integrative model that we believe best captures how self-control, emotional and interoceptive processes causally interact in the pathogenesis of AN. In this model, AN behaviors are not caused by interoceptive abnormalities, but rather interact with changes in emotional regulation and feelings of loss of self-control, subsequently leading to interoceptive deficits downstream. To capture a later stage in the pathogenesis of AN, we show how AN behaviors are maintained as a result of feedback among components in the model. We briefly explain future plans to further complement the model using a semi-structured interview to probe patient perspectives in AN. To develop a more valid understanding of AN, this model will have to be integrated into pluralistic approaches that include patient perspectives. (shrink)

Cook et al. argue that mirror neurons originate from associative learning processes, without evolutionary influence from social-cognitive mechanisms. We disagree with this claim and present arguments based upon cross-species comparisons, EEG findings, and developmental neuroscience that the evolution of mirror neurons is most likely driven simultaneously and interactively by evolutionarily adaptive psychological mechanisms and lower-level biological mechanisms that support them.

We contend that many of the criticisms of the American Psychological Association’s current Ethics Code are based on faulty assumptions and insufficient information. While the APA Ethics Committee values commentary on perceived shortcomings of the current Ethics Code as an important aspect of the current revision process, O’Donohue’s article contains inaccuracies that should be addressed. We clarify the functioning of the Ethics Code and the APA adjudication system, including explaining changes made to adjudication in light of the Commission on Ethics (...) Processes. We also explain the transparent, open process the APA has already undertaken to create a revised Ethics Code that is visionary and transformational. (shrink)

Ensuring that life-saving antimicrobials remain available as effective treatment options in the face of rapidly rising levels of antimicrobial resistance will require a massive and coordinated global effort. Setting a collective direction for progress is the first step towards aligning global efforts on AMR. This process would be greatly accelerated by adopting a unifying global target — a well-defined global target that unites all countries and sectors. The proposed pandemic instrument — with its focus on prevention, preparedness and response — (...) represents an ideal opportunity to develop and adopt a unifying global target that catalyzes global action on AMR. We propose three key characteristics of a unifying global target for AMR that — if embedded within the pandemic preparedness instrument — could rally public support, funding, and political commitment commensurate with the scale of the AMR challenge.

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

What is it to suspend judgment about whether p? Much of the recent work on the nature and normative profile of suspending judgment aims to analyze it as a kind of doxastic attitude. On some of these accounts, suspending judgment about whether p partly consists in taking up a certain higher-order belief about one's deficient epistemic position with respect to whether p. On others, suspending judgment about whether p consists in taking up a sui generis attitude, one that takes the (...) question of whether p? as its content. In this paper, I defend an account on which suspending judgment about whether p is not a matter of taking up a doxastic attitude, but rather a way of intentionally omitting to judge whether p. I then close with a discussion of how an account like mine, which sees suspending judgment as fundamentally practical, rather than doxastic, can accommodate what appear to be distinctively epistemic reasons to suspend judgment.

An ideal vision model accounts for behavior and neurophysiology in both naturalistic conditions and designed lab experiments. Unlike psychological theories, artificial neural networks (ANNs) actually perform visual tasks and generate testable predictions for arbitrary inputs. These advantages enable ANNs to engage the entire spectrum of the evidence. Failures of particular models drive progress in a vibrant ANN research program of human vision.

Mrs. Dall, in her article A Seventh-Century English Edition of Virgil , shows that Virgil glosses taken from marginalia in the same MS. of the poems often preserve something of their original coherence in the two kindred glossaries, Affatim and the Second Amplonian, in spite of all the reshuffling of these two collections. Thus a small group of Virgil items appears in Affatim on p. 491 of Goetz's apograph : Carecta, Crateras, etc. The second last of this ‘Virgil cluster’ is (...) Cada: vasa vinaria. It appears also in Ampl. II. Ca[t]da: vas vinaria, and in Ampl. I. Cada: vasa vinaria, and is apparently taken , ultimately or immediately, from a marginal annotation on Aen. 1, 195 ‘uina bonus quae deinde cadis onerarat Acestes’ for in the Virgil Glossary printed by Goetz in C.G.L. IV. 427–470 we find Cadis: vasis vinariis. (shrink)

The abbreviation-symbols of the Romans, found in ancient uncial MSS., may be roughly divided into three classes: Those peculiar to juristic writing, e.g. R.P. ‘res priuata’ , Q.D.R.A. ‘qua de re agitur.’ They are properly called ‘notae iuris.’ They abound in the famous Verona MS. of Gaius. A few used in histories, etc., e.g. R.P. 'respublica' , Q. ‘Quintus’ . Valerius Probus, who compiled a manual of ancient Notae, calls this class ‘notae publicae’. They appear in such MSS. as the (...) codex Puteanus of Livy ; and since they have been transferred into modern editions of the Latin historians, etc., no one is at a loss to interpret them nowadays, although they puzzled mediaeval scribes. Symbols of ordinary words of frequent occurrence in any type of literature, e.g. Q. ‘que.’ It is this class which is the subject of this article. (shrink)

This article presents a critique of two arguments made by S.P. Morris in his recent piece ‘The Trouble with Mascots’. The first argument is that the wrong of mascots is rooted in the falsity of the stereotyping generalizations that they create and perpetuate. The second is that when the group provides the name to itself, it is, in light of that fact, no less morally objectionable. These two arguments are related, for the second would be correct if falsity were in (...) fact the issue. As I argue, however, if we take a different view of the problem that generalizations present, the moral relevance of who does the naming becomes clear. (shrink)

In the October 1937 number of Philosophy of Science Lindsay has made certain criticisms of the adequacy of the “operational method” of analyzing and giving meaning to the concepts of physics, documenting his criticisms chiefly from my own writings. In these criticisms he has made statements as to the method which I would by no means accept. This is not characteristic of his paper only, for I have seldom indeed seen a printed discussion of the method which I would (...) accept as being an adequate or sometimes even fair representation of what I understand by it. It will perhaps pay therefore if I attempt to state what I conceive it to be all about, particularly since I have never attempted such a comprehensive statement and since my own ideas on the subject have been developing since I first wrote in the Logic of Modern Physics. For one reason I have hesitated to do this, for fear of seeming to subscribe to the not uncommon idea that we are dealing with some elaborate and profound new theory of the nature of knowledge or of meaning. I believe that I myself have never talked of “operationalism” or “operationism”, but I have a distaste for these grandiloquent words which imply something more philosophic and esoteric than the simple thing that I see. What we are here concerned with is an observation and description of methods which at least some physicists had already, perhaps unconsciously, adopted and found successful—the practise of the methods already existed. What I have attempted is to analyze these successful methods, not to set up a philosophical system and a theory of the properties that any method must have if it hopes to be successful. Since I was concerned with a technique already extant, my principal method of getting others to see what the technique involved has been to exhibit examples of the technique in action, rather than to attempt any exhaustive characterization of the technique itself.

In lieu of an abstract, here is a brief excerpt of the content:Stanley Cavell and Criticizing the University from WithinMichael FischerStanley Cavell has spoken often of his "lifelong quarrel with the profession of philosophy" but he has said less about the university as a whole and its pressures on all academic disciplines, philosophy included. 1 In Cavell's work, "academic" or "professional" philosophy takes shape in an institutional context he has not yet fully analyzed. I want here to extrapolate from Cavell's (...) work a critical, yet sympathetic, response to the university that I think is especially needed today, when the rise of the so-called corporate university is intensifying some of the professional pressures that Cavell resists.Cavell's discomfort with academic philosophy stems in part from what he regards as its narrowness, specifically, its marginalization of Ludwig Wittgenstein and other philosophers, not to mention Henry David Thoreau and Ralph Waldo Emerson, the comedies of remarriage, and other work that Cavell cares about. In his view, the professional marginalization of these writers partly results from their exemplifying what can seem to be a vague moral seriousness, even at times a prophetic urgency, that calls for something akin to conversion rather than issuing in specific conclusions or reforms. According to Cavell, academic philosophy, by contrast, subsumes moral concerns under ethics, a separate field in which the "point of conversation is getting the other to agree to, or to do, something." 2Although Cavell does not systematically analyze the institutional pressures on academic philosophy, he does drop some hints. As befitting a subject seeking legitimacy in the university, academic philosophy has aligned itself with teachable subjects such as science, as opposed to more elusive pursuits such as painting and creative writing, which [End Page 471] have been less at home in the university and where the necessity of university instruction may be less clear and the line between success and failure harder to draw. 3 What can be taught in academic philosophy is a method of analysis, mastery of which can be certified in students by professors and in professors by journals, promotion and tenure committees, and administrators. Subdividing philosophy into discrete fields such as ethics makes it even more manageable, or less susceptible to sweeping pronouncements that cannot be tested by experts. Finally, the interest in getting "the other to agree to, or to do, something" associates academic philosophy, or at least ethics, with measurable results and maybe even progress.The rise of the so-called corporate university has exacerbated the emphasis on teachable expertise and definable outcomes that I have been describing. Take the largest private university in the United States—the University of Phoenix—as a model that some state and non-profit private universities may be emulating as they struggle to cut costs, meet external expectations, and work with reduced budgets. At the University of Phoenix, the interest in measurable results gets recast as learning outcomes that teachers enable students to reach as efficiently as possible. Specialization narrows these learning outcomes to sharply defined skills, such as writing business memos, which students can master and build on. Finally, the emphasis on method does not simply depersonalize instruction; it reduces the need for instructors. Each instructor is tasked with teaching as many students as possible, sometimes through distance learning, with class size reaching a limit only when the learning outcomes cannot be delivered. Lacking tenure, these instructors can be replaced, like interchangeable parts, when they wear out or their student customers become too dissatisfied with them. At another rapidly growing for-profit university, DeVry, students unhappy with their instructors are assured, in the words of a campus dean, that "weak links" will be "fixed" in a "total quality management" environment. 4Along similar lines, Lindsay Waters has recently explored how "the corporate makeover of the university" and "the commercialization of higher education" have affected academic publishing. 5 Universities compete in an increasingly cutthroat marketplace and face an escalating insistence on results from state legislatures, federal agencies, accrediting associations, and boards. Capitulating to this "accountability culture" (EP, p. 20), bottom-line driven administrators have stepped up demands for faculty productivity, measured in quantitative terms by numbers of students taught, grants won, and, what most concerns Waters, books and [End...

As Fragment 46 of the first book of Sallust's Histories Maurenbrecher prints: Magnis operibus perfectis obsidium cepit per L. Catilinam legatum. This he takes in effect to mean that Lucretius Ofella after the completion of great siege works received reinforcements brought by L. Catiline legate of Sulla. The interpretation depends largely upon his contention that the phrase obsidium cepit is to be taken as equivalent to subsidium cepit, for which he claims the authority, ultimately, of Verrius Flaccus as represented by (...) Festus p. 193M s.v. obsidium. Though opinions may occasionally have differed as to the precise event documented by the fragment, this central assumption seems to have gone unchallenged by historians. Yet it rests upon remarkably insecure foundations. The reading cepit has scant authority and the interpretation of obsidium as subsidium none at all. It is in fact the result of misunderstanding the passage of Festus in which the text is embedded. In Lindsay's edition the Festus entry which is here quoted in full runs as follows: Obsidium tamquam praesidium, subsidium recte dicitur, cuius etiam auctor C. Laelius pro se apud populum : ‘Ut in nobis terra marique simul obsidium facerent.’ Et Sallustius historiarum I : ‘Magnis operibus perfectis obsidium coepit per L. Catilinam legatum.’ Coepit is the reading of the manuscript F, which has been generally accepted, while cepit appears only in the Aldine edition where it may well be an emendation or even an error, there being no obvious independent source which might have provided it. For Maurenbrecher it was merely the ‘correction’ of Corte who produced the earliest roughly chronological arrangement of the fragments of Sallust's Histories. (shrink)

Most commonly, the scientific realism debate is seen as dividing those who do and do not think that the striking empirical and practical successes of at least our best scientific theories indicate with high probability that those theories are ‘approximately true’. But I want to suggest that this characterization of the debate has far outlived its usefulness. Not only does it obscure the central differences between two profoundly different types of contemporary scientific realist, but even more importantly it serves to (...) disguise the most substantial points of actual disagreement between these two kinds of realists and those who instead think the historical record of scientific inquiry itself reveals that such realism is untenable in either form.

Whenever knowledge of the possible interpretation or conceptualization of some- thing helps in perceiving that thing, we say the processing is conceptually driven. That is, the process starts with conceptualization of what might be present and then looks for confirming evidence, biasing the processing mechanisms to give the expected result... Conceptually driven processing and data-driven processing almost always occur together, with each direction of processing contributing something to the total analysis.

It was the general practice until not at all long ago to look at Turner as one of the moderns, if not as one of the founding fathers of modern art. He was a man straddling the fence between two periods, but he was looking forward. In a history of art that marches through time, forever endorsing what is about to be forgotten, wrapping up, as it were, one style to open eagerly the package of the next, such a position (...) is most enviable for, no matter where the times may be going, it is a hallmark of greatness to be ahead of one's time. There were things to be explained, of course, Turner himself, a keen pessimist, did not approved of the future and had little use for the present.1 His love of art was schooled on Reynolds' Discourses, and he remained loyal to them; his poets were Thomson and Pope and, among contemporaries, the rather frigid but delicate Samuel Rogers, a classicist par excellence. Above all, however, Turner looked back to classical antiquity for training and guidance, and for the delectation of his heart. And the poetry of the ancients, such as he could obtain it in translation, was as important to him as their art. What does one do with a declared classicist whom a historicizing hindsight feels compelled to rescue as a man of the future by making him a Romantic? It is a challenge stylistic analysis likes to meet, for it goes beneath what it declares to be the surface of a work of art to find its style, the essence that must conform to the presumed spirit of the age in question. The triumphant result of such studies in depth is a forgone conclusion as much as it is a surprise to the uninitiated. The facade of the Louvre, for example, used to suffice to make it a building in the classical style; it took the acumen of a Wölfflin to prove that it really was "baroque." The more the artist struggled not to be of his time, the more, poor man, he betrayed to the analyst that he was of his time. The Louvre facade stands convicted of being "classicizing-baroque."2 · 1.

Readers of Phaedrus will have noticed that the rhythm of III. Ep. 34, Palam muttire plebeio piaculum est is unique.

We analyse the extent of possible computations following Hogarth ([2004]) conducted in Malament–Hogarth (MH) spacetimes, and Etesi and Németi ([2002]) in the special subclass containing rotating Kerr black holes. Hogarth ([1994]) had shown that any arithmetic statement could be resolved in a suitable MH spacetime. Etesi and Németi ([2002]) had shown that some relations on natural numbers that are neither universal nor co-universal, can be decided in Kerr spacetimes, and had asked specifically as to the extent of computational limits there. (...) The purpose of this note is to address this question, and further show that MH spacetimes can compute far beyond the arithmetic: effectively Borel statements (so hyperarithmetic in second-order number theory, or the structure of analysis) can likewise be resolved: Theorem A. If H is any hyperarithmetic predicate on integers, then there is an MH spacetime in which any query ? n H ? can be computed. In one sense this is best possible, as there is an upper bound to computational ability in any spacetime, which is thus a universal constant of that spacetime. Theorem C. Assuming the (modest and standard) requirement that spacetime manifolds be paracompact and Hausdorff, for any spacetime there will be a countable ordinal upper bound, , on the complexity of questions in the Borel hierarchy computable in it.
