Passive Cooling addresses all of the existing creative energyless means of keeping buildings cool. Unlike passive heating, which draws on the sun, passive cooling relies on three natural heat sinks - the sky, the atmosphere, and the earth to achieve temperature moderation. This book describes and evaluates mechanisms for coupling buildings to these sinks and ways of integrating multiple strategies into effective passive cooling systems.In "Radiative Cooling," Marlo Martin explains how the sky specifically outer space - acts as the ultimate (...) absorber to balance energy inputs from the sun as well as other sources. "Ventilative Cooling" by Subrato Chandra and "Evaporative Cooling" by John Yellott describe two ways in which the atmosphere can serve as a medium of heat transfer. The third natural heat sink the earth, is evaluated by Kenneth Labs in "Earth Coupling." Gene Clark in "Passive Cooling Systems" explains how each of these cooling resources affects the design of a building in a dramatically different way and shows how they can be combined. And Jeffrey Cook reviews the current state of basic and applied research projects and anticipates promising future directions of study and application.Because passive cooling techniques have a rich and diverse history of worldwide development and application, the editor has taken special care to relate developments in the United States to international practice and research, providing a broad base for professional redirection in building design.Jeffrey Cook is Regents Professor of Architecture at Arizona State University. Passive Cooling is volume 8 in the series Solar Heat Technologies: Fundamentals and Applications, edited by Charles A Bankston. (shrink)

The current study examined whether pigeons could learn to use abstract concepts as the basis for conditionally switching behavior as a function of time. Using a mid-session reversal task, experienced pigeons were trained to switch from matching-to-sample (MTS) to non-matching-to-sample (NMTS) conditional discriminations within a session. One group had prior training with MTS, while the other had prior training with NMTS. Over training, stimulus set size was progressively doubled from 3 to 6 to 12 stimuli to promote abstract concept development. (...) Prior experience had an effect on the initial learning at each of the set sizes but by the end of training there were no group differences, as both groups showed similar within-session linear matching functions. After acquiring the 12-item set, abstract-concept learning was tested by placing novel stimuli at the beginning and end of a test session. Prior matching and non-matching experience affected transfer behavior. The matching experienced group transferred to novel stimuli in both the matching and non-matching portion of the sessions using a matching rule. The non-matching experienced group transferred to novel stimuli in both portions of the session using a non-matching rule. The representations used as the basis for mid-session reversal of the conditional discrimination behaviors and subsequent transfer behavior appears to have different temporal sources. The implications for the flexibility and organization of complex behaviors are considered. (shrink)

Everett proposed resolving the quantum measurement problem by dropping the nonlinear collapse dynamics from quantum mechanics and taking what is left as a complete physical theory. If one takes such a proposal seriously, then the question becomes how much of the predictive and explanatory power of the standard theory can one recover without the collapse postulate and without adding anything else. Quantum mechanics without the collapse postulate has several suggestive properties, which we will consider in some detail. While these properties (...) are not enough to make it acceptable given the usual standards for a satisfactory physical theory, one might want to exploit these properties to cook up a satisfactory no-collapse formulation of quantum mechanics. In considering how this might work, we will see why any no-collapse theory must generally fail to satisfy at least one of two plausible-sounding conditions. (shrink)

This article argues that mirror neurons originate in sensorimotor associative learning and therefore a new approach is needed to investigate their functions. Mirror neurons were discovered about 20 years ago in the monkey brain, and there is now evidence that they are also present in the human brain. The intriguing feature of many mirror neurons is that they fire not only when the animal is performing an action, such as grasping an object using a power grip, but also when the (...) animal passively observes a similar action performed by another agent. It is widely believed that mirror neurons are a genetic adaptation for action understanding; that they were designed by evolution to fulfill a specific socio-cognitive function. In contrast, we argue that mirror neurons are forged by domain-general processes of associative learning in the course of individual development, and, although they may have psychological functions, they do not necessarily have a specific evolutionary purpose or adaptive function. The evidence supporting this view shows that mirror neurons do not consistently encode action “goals”; the contingency- and context-sensitive nature of associative learning explains the full range of mirror neuron properties; human infants receive enough sensorimotor experience to support associative learning of mirror neurons ; and mirror neurons can be changed in radical ways by sensorimotor training. The associative account implies that reliable information about the function of mirror neurons can be obtained only by research based on developmental history, system-level theory, and careful experimentation.

One of the main problems plaguing neo-logicism is the Bad Company challenge: the need for a well-motivated account of which abstraction principles provide legitimate definitions of mathematical concepts. In this article a solution to the Bad Company challenge is provided, based on the idea that definitions ought to be conservative. Although the standard formulation of conservativeness is not sufficient for acceptability, since there are conservative but pairwise incompatible abstraction principles, a stronger conservativeness condition is sufficient: that the class of acceptable (...) abstraction principles be strictly logically symmetrically class conservative . The article concludes with an examination of which classes of abstraction principles meet this criteria. (shrink)

A minimum voting age is defended as the most effective and least disrespectful means of ensuring all members of an electorate are sufficiently competent to vote. Whilst it may be reasonable to require competency from voters, a minimum voting age should be rejected because its view of competence is unreasonably controversial, it is incapable of defining a clear threshold of sufficiency and an alternative test is available which treats children more respectfully. This alternative is a procedural test for minimum electoral (...) competence. A procedural test for minimum electoral competence also succeeds in fulfilling adults’ duties to promote children’s rational and moral engagement with democracy. A minimum voting age should therefore be rejected, all things considered. A procedural test for minimum literacy and independent voting is the most justified means to ensure competency from voters and to promote the democratic agency of children. (shrink)

The Canadian Truth and Reconciliation Commission has been mandated to collect testimonies from survivors of the Indian Residential Schools system. The TRC demands survivors of the residential school system to share their personal narratives under the assumption that the sharing of narratives will inform the Canadian public of the residential school legacy and will motivate a transformation of settler identity. I contend, however, that the TRC provides a concrete example of how a politics of recognition fails to transform relationships between (...) Native and settler Canadians not only because it enacts an internalization of colonial recognition, but because it fails to account for what I call “settler ignorance.” Work in epistemologies of ignorance and epistemic oppression gives language to explain sustained denial and provide tools to further understand how settler denial is sustained, and how it can be made visible, and so challenged. For this task, Mills’s articulation of white ignorance should be expanded to a consideration of white settler ignorance. Over and above an account of white ignorance, such an account will have to consider the underlying logics of settler colonialism. This characterization of settler ignorance will show that the denial of past and ongoing violence against Indigenous peoples, through the reconstruction of the past to assert the primacy of settlers, is not explainable in terms of a lack of recognition but is rather structural ignorance.

Adorno thought that substantive change was not just desirable but also possible. He also offered ideas about what positive change might look like on the basis of his determinate negation of damaged life. This paper begins by exploring Adorno’s ideas about possibility and determinate negation. It also discusses his views about the sort of changes that might be made. Given Adorno’s ideas about the possibility of change, the paper ends by challenging Fabian Freyenhagen’s reading of Adorno as a methodological, epistemic, (...) and substantive negativist. (shrink)

Theodor W. Adorno often made reference to Immanuel Kant’s famous essay on enlightenment. Although he denied that immaturity is self-incurred, the first section of this article will show that he adopted many of Kant’s ideas about maturity in his philosophically informed critique of monopoly conditions under late capitalism. The second section will explore Adorno’s claim that the educational system could foster maturity by encouraging critical reflection on the social conditions that have made us what we are. Finally, this article will (...) demonstrate that Adorno links enlightenment to Kant’s idea of a realm of ends. (shrink)

Drawing from moral foundations theory, we show that differences in sensitivity to distinct moral norms help explain differences in the perceived fairness of punishing employees for off-duty deviance. We used an initial study to validate realistic examples of non-criminal behavior that were perceived as violating a specific moral foundation. Participants in the main study evaluated scenarios in which co-workers were fired for those behaviors, which took place outside of work but were revealed via social media. The extent to which participants (...) valued the norm violated by the co-worker positively predicted perceived fairness of the firing, and negatively predicted expressed intent to take retributive action against the responsible manager. This effect was moderated by the presence of a pre-existing organizational policy regarding off-duty conduct, which uniformly decreased negative reactions to the firing. Because social media now makes the revelation of an employee’s off-duty behavior to a broad audience increasingly likely, our results suggest the importance of developing an approach for responding to employee off-duty deviance while highlighting the relevance of moral pluralism to the study of third-party reactions.

Michael Dummett argues that acceptance of potentially infinite collections requires that we abandon classical logic and restrict ourselves to intuitionistic logic. In this paper we examine whether Dummett is correct. After developing two detailed accounts of what, exactly, it means for a concept to be potentially infinite (based on ideas due to Charles McCarty and Øystein Linnebo, respectively), we construct a Kripke structure that contains a natural number structure that satisfies both accounts. This model supports a logic much stronger than (...) intuitionistic logic, demonstrating that Dummett was wrong. We conclude by briefly examining ways to extend the account(s) in question to indefinitely extensible concepts such as Cardinal, Ordinal, and Set. (shrink)

Early in the COVID-19 pandemic there was widespread concern that healthcare systems would be overwhelmed, and specifically, that there would be insufficient critical care capacity in terms of beds, ventilators or staff to care for patients. In the UK, this was avoided by a threefold approach involving widespread, rapid expansion of critical care capacity, reduction of healthcare demand from non-COVID-19 sources by temporarily pausing much of normal healthcare delivery, and by governmental and societal responses that reduced demand through national lockdown. (...) Despite high-level documents designed to help manage limited critical care capacity, none provided sufficient operational direction to enable use at the bedside in situations requiring triage. We present and describe the development of a structured process for fair allocation of critical care resources in the setting of insufficient capacity. The document combines a wide variety of factors known to impact on outcome from critical illness, integrated with broad-based clinical judgement to enable structured, explicit, transparent decision-making founded on robust ethical principles. It aims to improve communication and allocate resources fairly, while avoiding triage decisions based on a single disease, comorbidity, patient age or degree of frailty. It is designed to support and document decision-making. The document has not been needed to date, nor adopted as hospital policy. However, as the pandemic evolves, the resumption of necessary non-COVID-19 healthcare and economic activity mean capacity issues and the potential need for triage may yet return. The document is presented as a starting point for stakeholder feedback and discussion. (shrink)

This paper applies concepts Deleuze developed in his ‘Postscript on the Societies of Control’, especially those relating to modulatory power, dividuation and control, to aspects of Australian schooling to explore how this transition is manifesting itself. Two modulatory machines of assessment, NAPLAN and My Schools, are examined as a means to better understand how the disciplinary institution is changing as a result of modulation. This transition from discipline to modulation is visible in the declining importance of the disciplinary teacher–student relationship (...) as a measure of the success of the educative process. The transition occurs through seduction because that which purports to measure classroom quality is in fact a serpent of modulation that produces simulacra of the disciplinary classroom. The effect is to sever what happens in the disciplinary space from its representations in a luminiferous ether that overlays the classroom. (shrink)

Leibniz has been widely praised for maintaining against the Newtonians of his day the view that space and time are relative. At the same time, he has been roundly criticized for allowing that we can distinguish absolute from merely relative motion. This distribution of applause and criticism, I will argue, is in a measure unjustified. For on the one hand, those arguments, found in his correspondence with Clarke, by which Leibniz seeks to reject the view that space and time are (...) “something absolute” are for the most part unsatisfactory, and on the other hand, Leibniz was not so naive as his critics have supposed in allowing absolute motions. Sections I ‐ V of this essay will be concerned with the former issue; Leibniz's views on motion will be taken up in Section VI. The chief interest in all of this for present‐day philosophers may lie, not so much in the historical issues concerning Leibniz and the Newtonians, but in a meta‐philosophical question which inevitably arises from the historical issues, namely, the question whether developments in science can undermine the soundness of philosophical arguments which appeal to ordinary usage.

Saul Kripke’s theory of truth suffers from expressive limitations – in particular, there are no extensional operators within that framework that allow one to characterize those sentences that fail to receive a truth value within the framework. Especially worrisome is the fact that there is no operator that outputs true on exactly the paradoxical sentences. In this paper I extend Kripke’s approach via the addition of extensional operators, which allows us to characterize many (but not all) such sentences, including the (...) paradoxical ones. (shrink)

There is a long history of women being underrepresented in biomedical and health research. Specific women’s health needs have been, and in some cases still are, comparatively neglected areas of study. Concerns about the health and social impacts of such bias and exclusion have resulted in inclusion policies from governments, research funders, and the scientific establishment since the 1990s. Contemporary understandings of foregrounding sex and gender issues within biomedical research range from women’s rights to inclusion, to links between human rights, (...) women’s health and sustainable development, and the increasing scientific and funding expectation for studies to consider the sex and gender implications of research design, results and impact. However, there are also exploitation issues to consider when foregrounding the inclusion of women as research participants, especially for research ethics committees and institutional review boards. A hidden risk is that exploitative research designs and practices may be missed, particularly by reviewers who may not have a nuanced understanding of gender-based harm. Utilizing contemporary case studies of ethics dumping, this paper highlights some of the concerns, and makes recommendations for IRBs/research ethics reviewers to help ensure that essential research is undertaken to the highest ethical standards.

How should we understand the duties between those who share in parenting a child? Those who engage in shared parenting have duties to each other derived from the child's interests, but they also have additional duties to each other as sharers in parenting. The intentional account of duties between parents appears unable to explain the stringency of duties of shared parenting, as it seems to permit a parent to relinquish unilaterally their duties of shared parenting. Drawing on the work of (...) Bratman, Alonso, and Scanlon, I develop a shared intention account of duties of shared parenting. Duties of shared parenting are constituted by the distinctive combination of the value of reliance in shared intentions, the importance of assurance in agreements, the significance of autonomy is deciding one's goals, and the entitlement to choose with whom one shares the intimacy of parenting. On this view, duties of shared parenting are shown to be stringent, but not duties of strict performance. Thus, I argue that the intentional account of parental duties is able to explain the stringency of duties of shared parenting. (shrink)

In this essay, I reject the suggestion that the just war tradition (JWT) does not apply to cyberwarfare (CW). That is not to say CW will not include grey areas defying easy analysis in terms of the JWT. But analogously ambiguous cases have long existed in warfare without undercutting the JWT's broad relevance. That some aspects of CW are unique is likewise no threat to the JWT's applicability. The special character of CW remains similar enough to other kinds of warfare; (...) the distinctions are more differences of degree than of kind. (shrink)

We develop and defend a novel interpretation of mainstream Marvel Comics—an interpretation we call the Fictional Journalism Interpretation. We then show how this interpretation of Marvel comics (i) challenges standard accounts of the manner in which fictional truths are generated by fictions and (ii) provides us with novel, interesting, and in some cases simpler explanations of, and understandings of, phenomena within these comics that are hard to deal with adequately on more traditional accounts, including both contradictions in the fiction and (...) various metafictional storytelling strategies. We conclude by defending the view from a number of objections. (shrink)

There is broad agreement that child labor is wrong and should be eliminated. This chapter examines the three main moral objections to child labor and considers their limitations: harm-based objections, objections from failing to benefit children, and objections from exploitation. Harm-based objections struggle with baselines for comparison and difficulties with Non-Identity problems. Even if child labor is not harmful, it may be wrong because it prevents children from enjoying other benefits, such as schooling. However, is schooling necessarily more beneficial for (...) children than work? Some kinds of child labor may not be harmful, and may benefit children, but they may still be wrong because they are exploitative. I consider some ways to address exploitative child labor, inspired by campaigns led by child workers. The chapter ends with a surprising conclusion that challenges the broad consensus with which we began: we may have duties to promote child labor. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Graffiti and Colonial Unknowing:A Comment on Mishuana Goeman's "Caring for Landscapes of Justice in Perilous Settler Environments"Anna Cookin "caring for landscapes of justice in Perilous Settler Environments," Dr. Goeman shows how the NDN Collective's initiatives, Chemehuevi photographer Cara Romero's Tongvaland project, and the works of Gabrieliño Tongva artist Mercedes Dorame "exemplify communities of care" that work toward "the unmapping of settler terrains" ("Caring for Landscapes" 51). Her address highlights (...) how these cartographic art productions are processes of (re)mapping that challenge colonial spatialities. Drawing on Michi Saagig Nishnaabeg scholar Leanne Betasamosake Simpson's poem "i am graffiti," Goeman frames these art works as Indigenous graffiti, insofar as they are everyday acts of resurgence1 that resist erasure and enact rematriation.My comments aim to articulate how Romero's and Dorame's works both reveal and disrupt a colonial unknowing by showing the cracks of settler colonial spatiality. I take Goeman's address to illustrate that the changing of minds and unsettling of settler identity will not occur through argumentation, facts, and figures alone, but rather through aesthetic and cartographic practices that "provide a way of seeing Indigenous futurities and relationalities" ("Caring for Landscapes" 52).Maps as Tools of Settler ColonialismIn order to highlight how these art practices enact a kind of (re)mapping that breaks through the veneer of colonial permanence, we first need to consider the way mapping transforms land into property in the service of Indigenous erasure and land dispossession. In her address, Goeman offers a short history of what is now called Los Angeles through the lens of dispossession that occurs through "international claiming of property and burgeoning US property law" ("Caring for Landscapes" 53). Tovaangar was divided into Spanish (and [End Page 64] then Mexican) land grants that, after 1846, were "registered under the US as property" (Goeman, "Caring for Landscapes" 53; emphasis added). The Land Act of 1851 "established the domestication of the California landscape under US governance" by legitimating existing Mexican land rights and mapping out territory yet "unclaimed" ("Caring for Landscapes" 54). The mapping of this so-called "unclaimed" territory propelled a violent erasure of California Indians by "establishing new and ongoing commerce centers" ("Caring for Landscapes" 53). Land was transferred into property—as a thing owned—without "the consent of those who … lived on the land since time immemorial, following the settler structure of passing land between Christian nations" ("Caring for Landscapes" 53). By showing how property rights legitimate conquest and violence, Goeman illustrates how mapping has been (and continues to be) an "essential settler-colonial tool to domesticate land in Southern California and propel development" ("Caring for Landscapes" 54). While she demonstrates how the mapping of Tovaangar using 493 hand-drawn Diseños maps served to sever Indigenous communities (and their relationships with land, such as the Gabrieliño Tongva with the San Gabriel Mountains), she emphasizes that this is an ongoing process that has not been left in a distant past. Newer maps that may seem more objective and scientific with "better models of scale or a more realist representation" remain, at their core, maps of dispossession ("Caring for Landscapes" 54).The very desire to objectively determine location by assigning latitude and longitude reveals a colonial spatiality, which "territorialize[s] the physical landscape by manufacturing categories and separating land from people" and conceives of space in terms of property logics (Goeman, "[Re]Mapping Indigenous Presence" 296). In addition to Indigenous land dispossession, this colonial spatiality rejects relationality by creating dualist boundaries between human and non-human, in which land is the raw material for human development and the creation of culture. Cherokee philosopher Brian Burkhart speaks of relationality in terms of locality, which he defines as "being-fromthe-land, knowing-from-the-land, and meaning-from-the-land" (Indigenizing Philosophy xvii). The severing of locality can be understood in terms of the transformation of land as relative to inert matter to be acted upon. Mapping serves as a tool of settler colonial erasure insofar as it delocalizes "land as the relational ground of kinship" into "land as a mere object that only has meaning or value in relation to people" ("Indigenizing Philosophy...

In this article we attempt to complicate traditional--and, we argue, limited and exclusionary--definitions of interdisciplinarity as the bringing into dialogue of established disciplines without questioning the parameters and practices of those disciplines. We propose that interdisciplinarity instead might mean teaching and learning among, between, and in the midst of those of innate or learned capacities--not only college faculty but also students and staff. To illustrate this more radical iteration of interdisciplinarity, we draw on a range of definitions of the key (...) terms, “discipline” and “faculty,” and we offer a case study of a workshop we co-facilitated in which we brought differently positioned individuals together to engage in the educational process and the production of knowledge. We hope that this discussion contributes to expanding the notions and practices of interdisciplinarity. (shrink)

Summary Theatre offers an opportunity for communities to think with and through fiction. We come together to hear and tell stories because it is moving, both in the literal and the figurative sense: it changes us. Theories from cognitive science of embodied cognition make clear that making sense of theatre is a full-bodied affair. In this essay, I argue that we can see moments when theatre invited its audience to think in new ways by shifting theatrical conventions. I explore how (...) a contemporary production of Hamlet, Pan Pan’s production of “The Rehearsal: Playing the Dane”, brings its audience to question the stability of the self and text by altering the conventions around casting and representation. This is theatre that I may not understand in a traditional way, but this gives me a way to understand a new way of thinking about the world around me. It is theatre I can use. (shrink)

Es bestehen tiefgreifende Zusammenhänge zwischen Leibniz' Mathematik und seiner Metaphysik. Dieser Aufsatz hat das Ziel, das Verständnis für diese beiden Bereiche zu erweitern, indem er Leibniz' Mereologie (die Theorie der Teile und des Ganzen) näher untersucht. Zunachst wird Leibniz' Mereologie primär anhand seiner Schrift “Initia rerum mathematicarum metaphysica" rekonstruiert. Dieses ehrgeizige Programm beginnt mit dem einfachen Begriff der Kompräsenz, geht dann iiber zu komplexeren Begriffen wie Gleichheit, Ähnlichkeit und Homogenität und kulminiert letztlich in der Leibnizschen Definition der Begriffe Teil, Ganzes (...) und Komposition. Im Verlauf des Aufsatzes werden auch weitere Erkenntnisse in anderen Bereichen gewonnen, so z. B. in bezug auf die Identität des Ununterscheidbaren. Schließlich werde ich im Rahmen der vorgelegten Theorie versuchen, ein Mißverständnis bezüglich Leibniz' Analogie zwischen Monaden und mathematischen Punkten, welche sich auf die Räumlichkeit der Monaden bezieht, auszuräumen.

One classical version of cosmological argument, defended famously by Thomas Aquinas and Duns Scotus, deduces the existence of a First Cause from the existence of a particular sort of causal series: one that is ‘essentially ordered’. This argument has received renewed defence in recent work by Feser, Cohoe, and Kerr. I agree with these philosophers that the argument is sound. I believe, however, that the standard defence given of the ECA in these philosophers can be complemented by a formulation that (...) appeals to the powers theory of possibility. This approach to possibility has been defended in recent years by, for example, Pruss, Jacobs, and Vetter. In this article, I show how this modal theory allows us to defend the ECA in a way that is dialectically advantageous as well as clarifying. (shrink)

_ Source: _Volume 10, Issue 2, pp 193 - 207 Julian, in a Syriac fragment of his _Contra Galilaeos_, attacked the resurrection narratives in Matthew and Mark, because they were inconsistent with each other concerning the time of the arrival of the women to the tomb, the nature of the being they met in the tomb, and the women’s subsequent actions. Other texts in Syriac and Latin indicate the probability that Julian took over the substance of his argument from Porphyry.

We extend the Embracing Revenge account of the semantic paradoxes by constructing two distinct consequence relations that reflect, in different ways, the transfinitely-many-valued semantics developed in earlier work. In particular, we adapt the underlying ideas of “gappy” approaches based on K3, and “glutty” approaches based on LP, to the Embracing Revenge framework, by treating the infinitely many non-classical truth values as infinitely many ways that a sentence might fail to receive a classical truth value in the former case, and as (...) infinitely many ways that a sentence might receive both classical truth values in the latter. In order to obtain deductive systems that are very nearly classical, we need to utilize different conditionals (and different negations) in each logic. (shrink)

This essay introduces a novel framework to studying many-valued logics – the movable truth value (or MTV ) approach. After setting up the framework, we will show that a vast number of many-valued logics, and in particular many-valued logics that have previously been given very different kinds of semantics, including C, K3, LP, ST, TS, RM fde, and FDE, can all be unified within the MTV -logic approach. This alone is notable, since until now RM fde in particular has resisted (...) attempts to provide it with the _same kind_ of many-valued semantics as the other logics in this list. New proofs of the duality between LP and K3, and of the self-duality of C, ST, TS, and RM fde, are presented. The essay will conclude with a discussion of directions that further research might take.
