People who believe they have greater efficacy to address climate change are more likely to engage in pro-environmental behaviour. To confront the climate crisis, it will therefore be essential to understand the processes through which climate change efficacy is promoted. Some interventions in the literature assume that efficacy emerges from analytic reasoning processes: that it is deliberative, verbal, conscious, and influenced by information and education. In the current paper, we critique this notion. We review evidence showing that climate change efficacy (...) perceptions are (a) associated with climate-related distress and threat, (b) prescribed by social norms, (c) associated with social desirability and identity-expressive concerns, (d) surprisingly difficult to change through explicit, verbal instruction, but (e) responsive to imagery. We conclude by examining applied implications of these five propositions and discuss why non-analytic processes might (ironically) be beneficial for sustaining green activism. (shrink)

Many of the haemopoietic cell growth factors have now been purified to homogeneity and their structural genes cloned. Methods are also now available for obtaining pure populations of haemopoietic cells. The use of such cells, in combination with pure growth factors, has provided intriguing information about the biological activities and mode of action of the factors in faciliating survival, proliferation and differentiation of the haemopoietic cells.

Recently, two apparently quite different duality-based approaches to automata minimisation have appeared. One is based on ideas that originated from the controllability-observability duality from systems theory, and the other is based on ideas derived from Stone-type dualities specifically linking coalgebras with algebraic structures derived from modal logics. In the present paper, we develop a more abstract view and unify the two approaches. We show that dualities, or more generally dual adjunctions, between categories can be lifted to dual adjunctions between categories (...) of coalgebras and algebras, and from there to automata with initial as well as final states. As in the Stone-duality approach, algebras are essentially logics for reasoning about the automata. By exploiting the ability to pass between these categories, we show that one can minimize the corresponding automata. We give an abstract minimisation algorithm that has several instances, including the celebrated Brzozowski minimisation algorithm. We further develop three examples that have been treated in previous works: deterministic Kripke frames based on a Stone-type duality, weighted automata based on the self-duality of semimodules, and topological automata based on Gelfand duality. As a new example, we develop alternating automata based on the discrete duality between sets and complete atomic Boolean algebras. (shrink)

The authors claim that disciplinary epistemologies—disciplinary habits of mind and ways of thinking—offer productive lenses for observing teaching practices. Furthermore, they argue that educational developers who draw from multiple epistemologies in combination provide rich evidence with regard to teaching and learning and can speak to academic colleagues from an array of disciplines. Clarity is provided for career paths in educational development for colleagues from academic disciplines who are contemplating part‐ or full‐time work in a teaching center. The authors hope that (...) this opening collection develops into a toolkit and area of inquiry about disciplinary approaches to the practice of educational development. (shrink)

Born of a terrible insomnia--"a dizzying lucidity which would turn even paradise into hell"--this book presents the youthful Cioran, a self- described "Nietzsche still complete with his Zarathustra, his poses, his mystical clown's tricks, a whole circus of the heights." On the Heights of Despair shows Cioran's first grappling with themes he would return to in his mature works: despair and decay, absurdity and alienation, futility and the irrationality of existence. It also presents Cioran as a connoisseur of apocalypse, a (...) theoretician of despair, for whom writing and philosophy both share the "lyrical virtues" that alone lead to a metaphysical revelation. "No modern writer twists the knife with Cioran's dexterity. . . . His writing . . . is informed with the bitterness of genuine compassion."--Bill Marx, Boston Phoenix "The dark, existential despair of Romanian philosopher Cioran's short meditations is paradoxically bracing and life-affirming. . . . Puts him in the company of Nietzsche and Kierkegaard."-- Publishers Weekly, starred review "This is self-pity as epigram, the sort of dyspeptic pronouncement that gets most people kicked out of bed but that has kept Mr. Cioran going for the rest of his life."--Judith Shulevitz, New York Times Book Review Emil M. Cioran (1911-1995) is the author of numerous works, including The Fall into Time, A Short History of Decay, and Tears and Saints. (shrink)

We sought to gain more insight into the effects of attention focus and time constraints on skill learning and performance in novices and experts by means of two complementary experiments using a table tennis paradigm. Experiment 1 showed that skill-focus conditions and slowed ball frequency disrupted the accuracy of experts, but dual-task conditions and speeded ball frequency did not. For novices, only speeded ball frequency disrupted accuracy. In Experiment 2, we extended these findings by instructing novices either explicitly or by (...) analogy . Explicitly instructed novices were less accurate in skill-focused and dual-task conditions than in single-task conditions. Following analogy instruction novices were less accurate in the skill-focused condition, but maintained accuracy under dual-task conditions. Participants in both conditions retained accuracy when ball frequency was slowed, but lost accuracy when ball frequency was speeded, suggesting that not attention, but motor dexterity, was inadequate under high temporal constraints.

The star-nosed mole is aptly named. Its distinctive snout consists of 22 tendrils ringing a pair of nostrils and, from some angles, the entire setup resembles a misshapen star. The tendrils are fleshy and look a bit like fingers, and, like fingers, they have a certain dexterity. But why? Why does the mole have such a singular appendage as opposed to something more ordinary? What is the function or purpose of this bizarre structure? From the dedicated work of Ken Catania, (...) of Vanderbilt University, and colleagues, it appears that the appendage facilitates rapid handling of small prey items, making it advantageous for an organism whose diet consists of tiny invertebrates. We might therefore hazard that this feature arose evolutionarily because it conferred this benefit. But the matter is difficult to resolve, because current utility does not permit a straightforward inference of a reason for existence. -/- A correction has been published: BioScience, Volume 72, Issue 7, July 2022, Page 708.

The current outbreak of Ebola virus infection in West Africa continues to spread. Several patients have now been treated in the United States and preparations are being made for more. Because of the strict isolation required for their care, questions have been raised about what diagnostic and therapeutic interventions should be available. I discuss the ethical challenges associated with caring for patients in strict isolation and personnel wearing bulky protective gear with reduced dexterity and flexibility, the limitations this may place (...) on available treatments and the permissibility of consequent departures from the standards of care. Restricting access to some interventions such as surgery requiring an operating room, advanced imaging, etc. is reasonable due to concern for protecting other patients, visitors and staff. Cardiopulmonary resuscitation is a special case and the implications for withholding this intervention in situations where it may be desired is discussed, especially with respect to those patients who have suspected, but not proven, infection. These same restrictions are also considered under conditions where there are scarce resources and thus limited numbers of patients may receive care. While it is to be hoped that there is only limited and sporadic infection with Ebola virus in the US, careful thought must be given to the care of these patients under the unusual circumstances demanded by their isolation. I argue that an altered standard of care is reasonable and ethically acceptable under certain conditions. (shrink)

Internationally, there is an on-going dialogue about how to professionalize ethics consultation services . Despite these efforts, one aspect of ECS-competence that has received scant attention is the liability of failing to adequately capture all of the relevant moral considerations in an ethics conflict. This failure carries a high price for the least powerful stakeholders in the dispute. When an ECS does not possess a sophisticated dexterity at translating what stakeholders say in a conflict into ethical concepts or principles, it (...) runs the risk of naming one side's claims as morally legitimate and decrying the other's as merely self-serving. The result of this failure is that one side in a dispute is granted significantly more moral weight and authority than the other. The remedy to this problem is that ECSs learn how to expand the diagnostic moral lens they employ in clinical ethics conflicts. (shrink)

The use of networks as an explanatory framework is widespread in the literature that surrounds technology and information society. The three books reviewed here — The Wealth of Networks by Yochai Benkler, Decoding Liberation: The Promise of Free and Open Source Software by Samir Chopra and Scott Dexter, and The Exploit: A Theory of Networks by Alexander Galloway and Eugene Thacker — all make a claim to the novelty that networks provide to their subject matter. By looking closely at (...) the way in which the network is utilized in each of the texts, this review attempts to question the extent to which a network analysis can ground a claim about a discontinuity in technology, society or economics.

The deeply imaginative structure of Dungeons Dragons (DD) can allow for players to explore the intricacies of gender and sexuality in creative and potentially radical ways. One would be hard pressed to argue that cartoonishly large breasts and skin‐tight leather skirts really allow for dexterous swordplay or quick getaways. DD liberates us from the limitations of our sex by making male and female characters equal in terms of abilities. The shyest of men can be the most outspoken of wizards, the (...) most honest girl can play the most unscrupulous rogue, and the pacifist woman can don full armor and fly into a berserker rage on a group of bugbears ambushing her adventuring party because, after all, bugbears are her species enemy and she just can't help herself when they are around.

In lieu of an abstract, here is a brief excerpt of the content:Response to C. Victor Fung and Leonard Tan, “‘Love of All Wisdoms’: Toward A Multiphilosophical Approach To Music Education”Lauren Kapalka RichermeFung and Tan’s arguments regarding the limits of our profession’s longstanding narrow focus on Eurocentric and American philosophical traditions are crucially important, and I think the majority of PMER readers will agree about the need to engage with philosophies written by those from diverse geographic locations and with other (...) forms of contrasting lived experiences. Additionally, this essay contains many thoughtful clarifications, including the importance of local and individualized needs, accruing philosophical wisdoms over time, and ongoing reflexivity. I found the conceptualization of boundaries “as a connecting agent rather than a separation device” particularly intriguing. Moreover, I applaud Fung and Tan for their work outside of this paper; their efforts to translate and extend various Asian philosophical ideas have certainly enriched the graduate philosophy classes that I teach.1 For me, the joy of any philosophical inquiry is the questions and imaginings it incites, and these authors have certainly given me a lot to contemplate. I begin this response with a couple of wonderments and then provide a possible extension of this valuable work. [End Page 185]One of my wonderments regards the relationship between culturally sustaining pedagogy and the proposed multiphilosophical approach. Fung and Tan write, “Ontological and axiological questions regarding the meaning of music in education and in the broader life are still unaddressed” and specifically ask “To what extent should musics of the students’ cultural tradition be customized and incorporated in the curriculum?” Culturally Sustaining Pedagogy or CSP, which is a primary contemporary outgrowth of the multicultural education movement, provides a clear response. Django Paris and H. Sami Alim write that Culturally Responsive Pedagogy:seeks to perpetuate and foster—to sustain—linguistic, literate, and cultural pluralism as part of schooling for positive social transformation. CSP positions dynamic cultural dexterity as a necessary good, and sees the outcome of learning as additive rather than subtractive.... Culturally sustaining pedagogy exists wherever education sustains the lifeways of communities who have been and continue to be damaged and erased through schooling.2Given the similarities between this explanation and Fung and Tan’s description of a multiphilosophical approach, I wonder if they could say more about points of alignment and disagreement. Might their arguments serve as an extension of CSP?Another wonderment I have is: What does a multiphilosophical approach exclude? I’m intrigued by Fung and Tan’s rich metaphor of a Chinese medicine cabinet and find it applicable to an array of philosophies. Yet, equating students to “patients” and a music educator to a “doctor” who “writes a prescription for a patient” is incompatible with some philosophies. For example, such language implies a banking model of education that undermines Brazilian philosopher Paulo Freire’s core tenets.3 Given that no metaphor or philosophical approach can address everything, I wonder if in addition to inclusions, a multiphilosophical approach necessarily relies on certain exclusions. I spend the remainder of this response positing three potential ways that exclusions might extend Fung and Tan’s ideas.First, inclusive approaches such as Fung and Tan’s multiphilosophy necessarily exclude philosophies resistant to openness and varying viewpoints. Philosophies that forward single prescribed educational ends or limited ways of being musical cannot function within a multiphilosphical approach and therefore must be excluded. Moreover, Fung and Tan’s references to democracy and use of Dewey suggest that a main purpose of a multiphilosophical approach is to propagate liberal pluralism. Such thinking aligns with Meira Levinson’s ideas about liberal education. She writes: “liberal citizenship does require certain habits and virtues, and pluralism is rightly restricted to individuals holding conceptions of [End Page 186] the good which are compatible with liberal citizenship.”4 Specifically, Levinson argues that these habits and virtues include respecting the democratic process, paying attention to public issues, and public involvement through voting and other forms of engagement. While I agree with Fung and Tan that “contemporary diverse needs are localized and always evolving,” those needs exist within larger socio-political-economic structures that inevitably rely on certain exclusions. The nature of those exclusions informs how “diverse needs” are understood and addressed... (shrink)

Quantum mechanical measurements on a physical system are represented by observables - Hermitian operators on the state space of the observed system. It is an important question whether all observables may be realized, in principle, as measurements on a physical system. Dirac’s influential text ( [1], page 37) makes the following assertion on the question: The question now presents itself – Can every observable be measured? The answer theoretically is yes. In practice it may be very awkward, or perhaps even (...) beyond the ingenuity of the experimenter, to devise an apparatus which could measure some particular observable, but the theory always allows one to imagine that the measurement can be made. This Letter re-examines the question of whether it is possible, even in principle, to measure every quantum mechanical observable. Unexpectedly, ideas from com-. (shrink)

In the opinion of Aristotle and Plutarch the growth of latifundia and consequent decline of the citizen population at Sparta were due to the absence of restrictions on gifts and bequests of land. According to Plutarch this freedom of gift and bequest, so far as it applied to the κλροι or entailed estates, was introduced by the τρα of an ephor named Epitadeus, who removed the ban on gift and bequest imposed by Lycurgus.

The paper intends to objectively review the ecological understanding of Upaniṣhadic ṛṣis. Since ecology is a modern notion, it is required to precisely place it within the Upaniṣhadic thought. For that purpose, a possible ontological structure of Upaniṣhadic philosophy is sorted in which the discussion of ecology becomes meaningful. Upaniṣhadic ṛṣis conceived ecology as a part of their metaphysics, that is, one which is assisted by the devatas. There is a dependent coexistence between Devatas, Humans and the world. This feature (...) of Upaniṣhadic philosophy should not be treated as a declaration for environmental conservation. It is rather seen as a theory of consumption and calibration from both sides. Although ecology is integrated into the Upaniṣhadic metaphysics, it is not one of the subject matters of Upaniṣhads. An understanding of ecology traceable from Upaniṣhads is supplementary to Upaniṣhadic theory of Devatas. Thus, the author concludes that the Upaniṣhadic ecology is metaphysical rather than natural.

Tradicionalmente se ha entendido que la mejor teoría de la responsabilidad extracontractual es aquella que mejor explica los rasgos centrales de la práctica. En este sentido, los defensores de las teorías deontológicas, basadas en principios de justicia, han rechazado el poder explicativo del análisis económico del derecho. Han sostenido que no logra reconstruir la práctica dando sentido a sus conceptos centrales, ni al modo en que están relacionados. Por lo tanto, no puede explicar la pauta de inferencias que llevan a (...) un juicio de responsabilidad. En este trabajo me propongo mostrar que ambas teorías son capaces de explicar aspectos diferen- tes de la práctica. En contra de lo que se asume generalmente, el análisis económico del derecho y las teorías deontológicas no son teorías rivales, sino compatibles, puesto que tienen por objeto responder a preguntas distintas.

The considerable attention to financial interests in clinical research has focused mostly on academic medical centers, even though the majority of clinical research is conducted in community practice settings. To fill this gap, this article maps the practices and policies in 73 community hospitals and several hundred specialized facilities around the country for reviewing clinical investigators’ financial relationships with research sponsors. Community hospitals face a substantially different mix of issues than academic medical centers do because their physician researchers are usually (...) not employees, and more of their studies are later-phase, multicenter trials. Accordingly, community physicians stand to benefit personally from per capita payments, but they tend to have less direct influence over research findings when compared with their academic peers. These and other contrasts require separate guidance for community-based organizations that takes into account their particular needs, circumstances, and institutional capacities. (shrink)
