Background: Positive effects of acute exercise on cognitive performances in general inspired research that investigated the effects of acute exercise on specific cognitive subdomains. Many existing studies examined beneficial effects of acute exercise on subsequent set shifting performance in healthy adults. Set shifting, a subdomain of executive function, is the ability to switch between different cognitive sets. The results of existing studies are inconsistent. Therefore, a meta-analysis was conducted that pooled available effect sizes. Additionally, moderator analyses were carried out to (...) identify covariates that determine the magnitude of exercise-induced set shifting benefits.Methods: Medline, PsycINFO, and SPORTDiscus were searched for eligible studies. Hedges' g corrected standardized mean difference values were used for analyses. Random-effects weights were applied to pool effects. Potential moderation of the effect of acute exercise on subsequent set shifting performance by exercise intensity, type of exercise, participants' age, and type of control group were examined.Results: Twenty-two studies were included into analysis. All aggregated effect sizes ranged from small to moderate. Overall, a small significant beneficial effect was revealed. Heterogeneity of included effect sizes was moderate and significant. Moderator analyses revealed a larger average effect in older adults than for studies examining younger adults. Light exercise led to larger effects than moderate or vigorous exercise. Studies testing acute exercise against active control groups showed a noticeably smaller average effect than studies that used passive or cognitive engaging control groups. Interestingly, application of resistance or aerobic exercise led to no different average effect sizes. However, none of the tested covariates reached statistical significance.Conclusion: Acute exercise improves subsequent set shifting performance. However, effect sizes are small, making the relevance for everyday life questionable. The results indicate that older adults benefit more from acute exercise than younger adults do. Light intensity exercise seems most effective while the type of exercise does not seem to influence the magnitude of effects. Research designs with active control groups show the smallest average effect, raising concerns about placebo effects.PROSPERO registration number: CRD42019138799. (shrink)

ABSTRACT:While the literature on psychedelic medicine emphasizes the importance of set and setting alongside the quality of subjective drug effects for therapeutic efficacy, few scholars have explored the therapeutic frameworks that are used alongside psychedelics in the lab or in the clinic. Based on a narrative analysis of the treatment manual and post-session experience reports from a pilot study of psilocybin-assisted treatment for tobacco smoking cessation, this article examines how therapeutic frameworks interact with the psychedelic substance in ways that can (...) rapidly reshape participants' identity and sense of self. We identified multiple domains relating to identity shift that appear to serve as smoking cessation mechanisms during psilocybin sessions, each of which had an identifiable presence in the manualized treatment. As psychedelic medicine becomes mainstream, consensual and evidence-based approaches to psychedelic-assisted identity shift that respect patient autonomy and encourage empowerment should become areas of focus in the emergent field of psychedelic bioethics.

For many years, Charles Peirce maintained that all senses of the modal terms "possible" and "necessary" can be defined in terms of "states of information." But in 1896, he was motivated by his work in set theory to criticize that account of modality, and in 1905 he characterized that criticism as a return "to the Aristotelian doctrine of a real possibility ... the great step that was needed to render pragmaticism an intelligible doctrine." But since Peirce was a realist about (...) modality before 1896, and since he continued defining "possibility" in terms of "states of information" after that date, it is not clear exactly what he changed his mind about. In this essay I explain what it was that Peirce changed his mind about and why, in retrospect, he viewed that change as a decisive step in the development of pragmaticism. (shrink)

Dual-process models of cognition suggest that there are two types of thought: autonomous Type 1 processes and working memory dependent Type 2 processes that support hypothetical thinking. Models of creative thinking also distinguish between two sets of thinking processes: those involved in the generation of ideas and those involved with their refinement, evaluation, and/or selection. Here we review dual-process models in both these literatures and delineate the similarities and differences. Both generative creative processing and evaluative creative processing involve elements that (...) have been attributed to each of the dual processes of cognition. We explore the notion that creative thinking may rest upon the nature of a shifting process between Type 1 and Type 2 dual processes. We suggest that a synthesis of the evidence bases on dual-process models of cognition and of creative thinking, together with developing time-based approaches to explore the shifting process, could better inform the development of i..

Prioritized bases, i.e., weakly ordered sets of sentences, have been used for specifying an agent’s ‘basic’ or ‘explicit’ beliefs, or alternatively for compactly encoding an agent’s belief state without the claim that the elements of a base are in any sense basic. This paper focuses on the second interpretation and shows how a shifting of priorities in prioritized bases can be used for a simple, constructive and intuitive way of representing a large variety of methods for the change of belief (...) states—methods that have usually been characterized semantically by a system-of-spheres modeling. Among the methods represented are ‘radical’, ‘conservative’ and ‘moderate’ revision, ‘revision by comparison’ in its raising and lowering variants, as well as various constructions for belief expansion and contraction. Importantly, none of these methods makes any use of numbers. (shrink)

Critical-set views avoid the Repugnant Conclusion by subtracting some constant from the welfare score of each life in a population. These views are thus sensitive to facts about biographical identity: identity between lives. In this paper, I argue that questions of biographical identity give us reason to reject critical-set views and embrace the total view. I end with a practical implication. If we shift our credences towards the total view, we should also shift our efforts towards ensuring that (...) humanity survives for the long term. (shrink)

Semantic Leaps explores how people combine knowledge from different domains in order to understand and express new ideas. Concentrating on dynamic aspects of on-line meaning construction, Coulson identifies two related sets of processes: frame-shifting and conceptual blending. Frame-shifting is semantic reanalysis in which existing elements in the contextual representation are reorganized into a new frame. Conceptual blending is a set of cognitive operations for combining partial cognitive models. By addressing linguistic phenomena often ignored in traditional meaning research, Coulson explains how (...) processes of cross-domain mapping, frame-shifting, and conceptual blending enhance the explanatory adequacy of traditional frame-based systems for natural language processing. The focus is on how the constructive processes speakers use to assemble, link, and adapt simple cognitive models underlie a broad range of productive language behavior. (shrink)

This study examines a significant gap in the role of providing ethical guidance and support for community-based research. University and health-based ethical review committees in New Zealand predominantly serve as ‘gatekeepers’ that consider the ethical implications of a research design in order to protect participants and the institution from harm. However, in New Zealand, community-based researchers routinely do not have access to this level of support or review. A relatively new group, the New Zealand Ethics Committee, formed in 2012, responds (...) to the uneven landscape of access for community-based research. By offering ethical approval inclusive of the review of a project’s study design outside institutional settings, NZEC has endeavoured to move beyond a gatekeeping research governance function to that of bridge-building. This change of focus presents rich possibilities but also a number of limitations for providing ethical review outside conventional institutional contexts. This paper reports on the NZEC’s experience of working with community researchers to ascertain the possibilities and tensions of shifting ethics review processes from research governance to a focus on research ethics in community-based participatory research.

The following is an introduction to a roundtable panel of the American Political Science Association meeting (Normative Political Theory Division) held September 2, 1994, in New York City. I set out some main themes in the "care/justice debate," and suggest that the impasse between care proponents and liberal, neo-Kantian thinkers is perpetuated by caricatured construals of these theories; salient differences come into relief by addressing the ethical and political applications of these moral perspectives.

Dr. Strange sees Dr. Stephen Strange abandon his once-promising medical career to become a superhero with the ability to warp time and space, and to travel through various dimensions. In order to make this transition, he is required to abandon many of his previous assumptions about the way the world works and learn to see things in a new way. Importantly, this is not merely a matter of learning a few facts, or of mastering new techniques. Instead, Dr. Strange is (...) required to alter his conception of the basic nature of the world and of how he relates to it. In time, this change extends to his values as well, as Strange comes to embrace his role in safeguarding the human world from interdimensional threats. -/- It is tempting to interpret Dr. Strange’s experience as one that shows the limits of rational, scientific inquiry, or even of human knowledge more generally. However, in this essay, I’d like to explore a different interpretation: that Strange’s experience can most fruitfully be thought of as a scientific revolution, in which Strange moves from one way of carrying out scientific inquiry to a different, incompatible way of doing it. In order to do this, I’ll be exploring the work of philosopher and historian of science Thomas Kuhn, who wrote a book—The Structure of Scientific Revolutions--about just this topic. Among other things, Kuhn’s work introduced the highly useful (though commonly misunderstood) notion of a paradigm shift. -/- We’ll begin by exploring what Kuhn describes as normal science, which consists of applying a set of well-understood concepts and methods to problems of interest. This “puzzle-solving” aspect of science is exemplified by Strange’s early successes in medicine. During this stage, scientists have good reasons to avoid questioning the basic validity of their paradigm, and to instead blame any problems that arise on other factors, such as human error. (As fans will know, Strange is quite good at assigning blame in just this way.) A crisis only occurs when significant, serious anomalies have accrued, such as those that Strange encounters in the aftermath of his accident. Even then, however, the old paradigm will only be abandoned only if a new paradigm can be found. Again, Strange’s experience bears this out, as he is able to move on only when the Sorcerer Supreme introduces him to the Mystic Arts. -/- Along the way, we’ll consider what it means for a practice to count as a scientific paradigm, and why it’s not just “anything goes.” Among other things, a paradigm requires that practitioners agree on which problems are most important, which techniques are appropriate to which problems, and what exemplary models of successful work look like. The Mystic Arts of Strange’s world, unlike the pseudoscientific theories of our own, plausibly do quite well on these sorts of criteria. (shrink)

When everyone can be a publisher, what distinguishes the journalist? This article considers contemporary challenges to institutional roles in a digital media environment and then turns to three broad journalistic normative values - authenticity, accountability, and autonomy - that affect the credibility of journalists and the content they provide. A set of questions that can help citizens determine the trustworthiness of information available to them emerges from the discussion.

In recent years, attention has become a matter of increasing public concern. New digital technologies have transformed human attention materially and discursively, reorganizing perceptual practices and inciting debates about them. The essays in this special issue emerged from a set of panels focused on attention at the 4S conference in New Orleans in 2019. They are all, in various ways, concerned with shifts among attention’s many meanings: between payment and care, instinct and agency, or vulnerability and power. Drawing on Science (...) and Technology Studies sensibilities, these pieces examine how scientific and technical actors are invested in theorizing and capturing attention, while simultaneously engendering new forms of care, resistance, and critique. At a moment where the attention economy appears to be in transformative crisis, this collection maps a set of incipient directions that ask us to pay attention to not only attention itself but also to the many sociotechnical settings where experts and publics are shifting attention’s meaning and value.

We analyze and study the tracking of nonrigid complex targets of sports video based on mean shift fusion color histogram algorithm. A simple and controllable 3D template generation method based on monocular video sequences is constructed, which is used as a preprocessing stage of dynamic target 3D reconstruction algorithm to achieve the construction of templates for a variety of complex objects, such as human faces and human hands, broadening the use of the reconstruction method. This stage requires video sequences (...) of rigid moving target objects or sets of target images taken from different angles as input. First, the standard rigid body method of Visuals is used to obtain the external camera parameters of the sequence frames as well as the sparse feature point reconstruction data, and the algorithm has high accuracy and robustness. Then, a dense depth map is computed for each input image frame by the Multi-View Stereo algorithm. The depth reconstruction with a too high resolution not only increases the processing time significantly but also generates more noise, so the resolution of the depth map is controlled by parameters. The multiple hypothesis target tracking algorithms are used to track multiple targets, while the chunking feature is used to solve the problem of mutual occlusion and adhesion between targets. After finishing the matching, the target and background models are updated online separately to ensure the validity of the target and background models. Our results of nonrigid complex target tracking by mean shift fusion color histogram algorithm for sports video improve the accuracy by about 8% compared to other studies. The proposed tracking method based on the mean shift algorithm and color histogram algorithm can not only estimate the position of the target effectively but also depict the shape of the target well, which solves the problem that the nonrigid targets in sports video have complicated shapes and are not easy to track. An example is given to demonstrate the effectiveness and adaptiveness of the applied method. (shrink)

The papers in this volume are largely about research ethics and cover questions of consent, reproduction, pediatric research, ethical codes, and clinical relationships. Half the papers have this common aspect: they are conservative—in the sense of supporting the standard, prevailing, or popular view—but they shift the focus—supporting the standard views in terms of moral factors generally neglected by the literature. The volume provides a diverse set of papers for the reader: variously addressing abstract and concrete problems from within different (...) philosophical traditions. (shrink)

For sociologist Emile Durkheim, the “sacred” constitutes all those things “set apart and forbidden.” Within Evangelical Christianity, and to a lesser degree Protestantism in general, the sacred has arguably centered on the individual believer and her/his personal relationship with God and scripture. Recently, however, a growing movement within Evangelical Christianity has emphasized the sacred nature of relationships and community, culminating in the mantra “God is love.” This shift has set community above the personal in the hierarchy of sacred Evangelical (...) things, and is reminiscent of earlier progressive forms of Evangelicalism, such as Social Gospel Christianity. Rob Bell, an Evangelical author, pastor, and Oprah Network star, possibly best exemplifies this change and its ramifications, which extend from a postcolonial critique of mission work and evangelism to a move to more inclusive and even Universalist soteriology. Such efforts that have left Bell labeled as a heretic in some Evangelical circles. (shrink)

I distinguish, and discuss the relations between, five types of context-shift involving indexicals. For 'intentional' indexicals - indexicals whose value depends upon the speaker's intention - we can shift the context more or less 'at will', by manifesting one's intention to do so. For other indexicals we can shift the context through pretense. Following a number of authors, I distinguish two types of context-shifting pretense, corresponding to two sets of linguistic phenomena. The fourth type of case is (...) that of expressions which are not really indexical, but perspectival, and for which we do not need to appeal to the notion of context-shift in order to account for their shifty behaviour. The fifth category I introduce and discuss is that of 'shiftable indexicals'. Do we need it, given that we already have the other four categories? My answer is a qualified 'yes'. (shrink)

Complex problem solving is often an integration of perceptual processing and deliberate planning. But what balances these two processes, and how do novices differ from experts? We investigate the interplay between these two in the game of SET. This article investigates how people combine bottom-up visual processes and top-down planning to succeed in this game. Using combinatorial and mixed-effect regression analysis of eye-movement protocols and a cognitive model of a human player, we show that SET players deploy both bottom-up and (...) top-down processes in parallel to accomplish the same task. The combination of competition and cooperation of both types of processes is a major factor of success in the game. Finally, we explore strategies players use during the game. Our findings suggest that within-trial strategy shifts can occur without the need of explicit meta-cognitive control, but rather implicitly as a result of evolving memory activations. (shrink)

This paper offers a historical analysis of contemporary practices of shopping for vegetables in the highly dynamic context of urban Hanoi during the period from 1975 to 2014. Focusing on everyday shopping practices from a food safety perspective, we assess the extent to which the policy-enforced process of supermarketization has proven to be an engine of change in daily vegetable purchasing while improving food safety. In depicting transitions in shopping practices, we combine a social practices approach with historical analysis. Providing (...) a historical analysis of a broad and complex spectrum of everyday practices of purchasing fresh vegetables, we identify the key drivers of change. We discuss different modalities of shopping and demonstrate that no single retail modernization format can be said to exist. Rather than contrasting an idealized supermarket model with the traditional modalities of food shopping, we offer a varied, more diverse set of shopping practices that displays different strategies for coping with food safety issues. When discussed from a historical perspective, food practices are shown to be highly dynamic, being constantly reinvented and reconfigured by consumers who use their established skills, routines, and social networks to sometimes resist top-down enforced supermarketization while developing the coping strategies that best suit their local circumstances.

There is societal consensus that cancer clinical trial participation is unjust because some sociodemographic groups have been systematically underrepresented. Despite this, neither a definition nor an ethical explication for the justice norm of equity has been clearly articulated in this setting, leading to confusion over its application and goals. Herein we define equity as acknowledging sociodemographic circumstances and apportioning resource and opportunity allocation to eliminate disparities in outcomes, and we explore the issues and tensions this norm generates through practical examples. (...) We assess how equality-based enrollment structures in clinical cancer research have perpetuated historical disparities and what equity-based alternatives are necessary to achieve representativeness and an expansive conception of participatory justice in clinical cancer research. This framework addresses the breadth from normative to applied by defining the justice norm of equity and translating it into practical strategies for addressing participation disparities in clinical cancer research.

Neoliberalism is invariably presented as a governing regime of market and competition-based systems rather than as a set of migratory practices that are re-setting the ethical standards of the academy. This article seeks to explore the way in which neoliberalism is shifting the prevailing values of the academy by drawing on two illustrations: the death of disinterestedness and the obfuscation of authorship. While there was never a golden age when norms such as disinterestedness were universally practiced they represented widely accepted (...) aesthetic ideals associated with academic life. By contrast, neoliberal academics embrace a new set of assumptions and norms that stand in sharp relief to many of the values that were previously espoused. Practices that might have been regarded as ethically dubious by earlier generations of academics, such as grantsmanship, self-justificatory expressions of interestedness and tangential claims to authorship, are now regarded as legitimate and positive virtues in a more aggressive age of hyper-performativity.

The disruptions to everyday life wrought by the COVID-19 pandemic include distortions in the experience of time, as reported widely by ordinary citizens and observed by journalists and social scientists. But how does this temporal disruption play out in different time scales—in the individual day as opposed to the medium- and long-term futures? And how might place influence how individuals experience and understand the pandemic's temporal transformations? This essay examines a range of temporal disruptions reported in day diaries and surveys (...) submitted to the Everyday Life in Middletown project, an online archive that has been documenting ordinary life in Muncie, Indiana, USA since 2016. Viewing these materials as instances of life writing, the essay probes the interactions between temporal disruptions and the local setting as they inflect the autobiographical selves our writers construct in their pandemic writings. It shows how living in Muncie—a postindustrial city with its particular combination of historical, demographic, economic, social, and political dynamics—structures the autobiographical stories available to our writers, and how the disruption of time produces new variations and problems for life writing. In the midst of a global crisis, we glimpse the pandemic's reshaping of a local structure of feeling in which a pervasive, local narrative of civic decline frames individual self-fashioning.

How do scientists and theologians conceive new ways of mapping the world? Can parallels be found between the images they use, or the models they offer when new questions arise? I will explore Albert Einstein’s views on scientific imagination with the goal of contributing – at least within his own perspective – to answering these questions. Drawing on McGrath, I will first briefly describe Einstein’s desire for a unified vision of reality, the links between science and a ‘cosmic religion’, and (...) his overall ideas on transcendence. I will later further develop Einstein’s fundamental features of a cosmovision that grounds his work in physics, and encompasses his philosophical views on human existence and his general way of seeing the world. I will focus on Ideas and Opinions (1982), which will allow me to set the broad picture of his theory of everything and, at the same time, bring up the central aspects of Einstein’s ideas on the scientific imagination. Finally, I will briefly summarise my conclusions concerning Einstein’s views on the nature of scientific imagination as a mental device, especially regarding its twofold role in what I call ‘visual image play’ and conceptualization.

Although Saghai primarily focuses on distinguishing nudges from other forms of influence, ‘Salvaging the Concept of Nudge’ offers a definition of nudges that could blunt much of the moral criticism of nudging and clarify debates about specific policies.1 The definition he offers, however, restricts the class of nudges to include only those influences that counter an individual's preferences; thus, contrary to what Thaler and Sunstein say, nudges cannot be instances of libertarian paternalism.1 ,2According to Saghai, ‘A nudges B when A (...) makes it more likely that B will ϕ, primarily by triggering B's shallow cognitive processes, while A's influence preserves B's choice-set and is substantially non-controlling ’. Because the second condition—the substantial non-control condition—is supposed to ensure that nudges preserve freedom in a robust sense, this condition warrants careful attention.According to Saghai, A's influence is substantially non-controlling ‘when B could easily not ϕ if she did not want to ϕ’. To determine whether a particular influence constitutes a nudge, we must ask whether from B's perspective that influence is easily resistible. …. (shrink)

When reading the papers of Solomon, Thagard and Goldman, I observed their framing doing considerable explicit and implicit work. Framing, a visual metaphor, stimulated me to respond with images of one kind or another.

Task shifting is increasingly used to address human resource shortages impacting HIV service delivery in low- and middle-income countries. By shifting basic tasks from higher- to lower-trained cadres, such as Community Health Workers, task shifting can reduce overhead costs, improve community outreach, and provide efficient scale-up of essential treatments like antiretroviral therapies. Although there is rich evidence outlining positive outcomes that CHWs bring into HIV programs, important questions remain over their place in service delivery. These challenges often reflect concerns over (...) whether CHWs can mitigate HIV through a means that does not overlook the ethical and practical constraints that undergird their work. Ethical and practical guidance thus needs to become the cornerstone of CHW deployment. This paper analyzes such challenges through the lens of Ethical Principlism. We examined papers identifying substantive and ethical challenges impacting CHWs as they provide HIV services in low- and middle-income contexts. To do this, we analyzed papers written in English and published from year 2000 or later. These articles were identified using MEDLINE, Cochrane Database of Systematic Reviews, and Google Scholar databases. In total, 465 articles were identified, 78 of which met our inclusion criteria. Article reference lists and grey literature were also examined. CHWs experience specific challenges while carrying out their duties, such as conducting emotionally- and physically-demanding tasks with often inadequate training, supervision and compensation. CHWs have also been poorly integrated into health systems, which not only impacts quality of care, but can hinder their prospects for promotion and lead to CHW disempowerment. As we argue, these challenges can be addressed if a set of ethical principles is prioritized, which specifically entail the principles of respect for persons, justice, beneficence, proportionality and cultural humility. CHWs play a crucial role in HIV service delivery, yet the ethical challenges that can accompany their work cannot be overlooked. By prioritizing ethical principles, policymakers and program implementers can better ensure that CHWs are combatting HIV through a means that does not exploit or take their critical role within service delivery for granted.

In the scientific literature, there are accents that emphasize certain changes in the functioning of philosophy, which took place in connection with the establishment of the postulates of postmodernism as a new period in the development of culture, as a style of post non-classical scientific thinking, in fact, the content and hierarchy of values positions itself with a sophisticated departure from the classical and non-classical philosophical reflection. Philosophical and educational understanding of the methodology of research of dialogue and tolerance testified (...) to the relevance of their research in the development of the potential of today’s multicultural education and its growth in the cultural and educational space. Dialogue, dialogics and tolerance are represented by the mechanisms of meaning-making, axiology and praxeology: dialogical cognition of the interpersonal, social-group, societal, planetary world provides a certain "breakthrough" in the worldview-value coordinate system, in external-internal control of growth efficiency and its spiritual dimension. The axiological, ontological, educational-epistemological aspects of “fitting” a person into a new world context are precisely in the plane of philosophy, enriching the cultural fields of today’s education through integration in goal-setting, content, organizational and managerial conditions for teaching and upbringing value ideals, principles, methods of holistic study of a person and those that are relevant today and provide Homo educandus with a meaning-making knowledge.

Plagiarism is a pervasive challenge throughout academia perpetuated by the advent of technology, lack of ethical education, and the ambiguity in its definition. Plagiarism in the United States’ higher education settings has gained more attention over the years as international student population has increased. Considering how higher education institutions are growing as international spaces due to globalization, it is crucial to closely examine ethical issues concerning the diverse and multicultural student population. A prevailing view of plagiarism asserts that international students’ (...) plagiarized texts are influenced by their ethical judgment and cultural backgrounds. This invites the question of whether ethical decision-making processes and cross-cultural perspectives are taken into consideration when instructors encounter instances of plagiarism committed by international or multicultural students. This paper intends to expand on the concept of culture in regard to the ethical dilemmas of plagiarism. Extending the discussions of cross-cultural influences surrounding plagiarism and ethical judgments in higher education, we position ourselves as viewing culture through the expanded lenses of macro- and micro-level cultural practices. In response to the internationalization of higher education, we advocate for changes in higher education curricula and instruction towards more cultural responsiveness and inclusivity. Instead of questioning or criminalizing ethics based on cultural background, especially in the cases of plagiarism committed by international students, we suggest approaching culture using the expanded perspectives of macro- and micro-cultural practices. The paper also provides recommendations for higher education instructors when tackling ethical dilemmas while preventing and managing situations of plagiarism. (shrink)

One of the major reasons for the success of answer set programming in recent years was the shift from a theorem proving to a constraint programming view: problems are represented such that stable models, respectively answer sets, rather than theorems correspond to solutions. This shift in perspective proved extremely fruitful in many areas. We believe that going one step further from a “hard” to a “soft” constraint programming paradigm, or, in other words, to a paradigm of qualitative optimization, (...) will prove equally fruitful. In this paper we try to support this claim by showing that several generic problems in logic based problem solving can be understood as qualitative optimization problems, and that these problems have simple and elegant formulations given adequate optimization constructs in the knowledge representation language.

This article elaborates local selective realism in view of the shifting from classical to quantum electrodynamics. After some introductory remarks, we critically address what we call global selective realism, hence setting forth the background for outlining local selective realism. When examining the transition from classical to quantum electrodynamics, we evaluate both continuities and discontinuities in observational features, mathematical structures, and ontological presuppositions. Our argument leads us to criticise the narrow understanding of limiting-case strategies, and to reject the claim that we (...) need a fully coherent theoretical framework to account for the transition from one theory to its successor in the case of electrodynamics. We close with a few remarks on the scope of local selective realism. (shrink)

Algebraic Set Theory, a reconsideration of Zermelo-Fraenkel set theory in category-theoretic terms, has been built up in the mid-nineties by André Joyal and Ieke Moerdijk. Since then, it has developed into a whole research program. This paper gets back to the original formulation by Joyal and Moerdijk, and more specifically to its first three axioms. It explains in detail that these axioms set up a framework directly linked to descent theory, a theory having to do with the shift from (...) local data to a global item in modern algebraic geometry. Fibered categories, introduced by Grothendieck, provide a powerful framework for descent theory: They formalize in a very general way the consideration of local data of different kinds over the objects of some base category. The paper shows that fibered categories fit Joyal and Moerdijk’s axiomatization in a natural way, since the latter actually aims to secure a descent condition. As a result, Algebraic Set Theory is shown to accomplish, not only an original and fruitful combination of set theory with category theory, but the genuine graft of a deeply geometric idea onto the usual setting of zfc.

A model of culture as a partially coherent system of signs comprised the most widely employed instrument for analyzing cultural meaning among the new cultural historians. However, the model failed to account for meanings that are produced by agents engaged in practices that are not guided by "reading" the contrasts among signs. It also encouraged some analysts to conceive the difference between sign system and concrete practice as that between what is graspable as an intellectual form and what remains inaccessibly (...) material or corporeal. This essay introduces three exemplars of the ties between signs and practices to show how the pragmatics of using signs comprises a structure and a generator of meaning in its own right. In the three exemplars, which are based on the tropes of metonymy, metaphor, and irony, I employ the analytic tools of linguistics to appreciate the non-discursive organization of practice. Analysis of the diverse logics for organizing practice offers promising means for investigating how signs come to seem experientially real for their users. Finally, this view of culture in practice suggests new hypotheses about the possible interdependencies as well as the lack of connection among the elements of a cultural setting. (shrink)

In the late 1940s and early 1950s Lorenzen developed his operative logic and mathematics, a form of constructive mathematics. Nowadays this is mostly seen as the precursor to the more well-known dialogical logic and one could assumed that the same philosophical motivations were present in both works. However we want to show that this is not always the case. In particular, we claim, that Lorenzen’s well-known rejection of the actual infinite as stated in Lorenzen (1957) was not a major motivation (...) for operative logic and mathematics. In this article, we claim that this is in fact not the case. Rather, we argue for a shift that happened in Lorenzen’s treatment of the infinite from the early to the late 1950s. His early motivation for the development of operativism is concerned with a critique of the Cantorian notion of set and related questions about the notion of countability and uncountability; only later, his motivation switches to focusing on the concept of infinity and the debate about actual and potential infinity.

We present a formalization of collections that Cornelius Castoriadis calls “magmas”, especially the property which mainly characterizes them and distinguishes them from the usual cantorian sets. It is the property of their elements to depend on other elements, either in a one-way or a two-way manner, so that one cannot occur in a collection without the occurrence of those dependent on it. Such a dependence relation on a set A of atoms (or urelements) can be naturally represented by a pre-order (...) relation $$\preccurlyeq $$ of A with the extra condition that it contains no minimal elements. Then, working in a mild strengthening of the theory $$\textrm{ZFA}$$, where A is an infinite set of atoms equipped with a primitive pre-ordering $$\preccurlyeq $$, the class of magmas over A is represented by the class $$LO(A,\preccurlyeq )$$ of nonempty open subsets of A with respect to the lower topology of $$\langle A,\preccurlyeq \rangle $$. The non-minimality condition for $$\preccurlyeq $$ implies that all sets of $$LO(A,\preccurlyeq )$$ are infinite and none of them is $$\subseteq $$ -minimal. Next the pre-ordering $$\preccurlyeq $$ is shifted (by a kind of simulation) to a pre-ordering $$\preccurlyeq ^+$$ on $${{\mathcal {P}}}(A)$$, which turns out to satisfy the same non-minimality condition as well, and which, happily, when restricted to $$LO(A,\preccurlyeq )$$ coincides with $$\subseteq $$. This allows us to define a hierarchy $$M_\alpha (A)$$, along all ordinals $$\alpha \ge 1$$, the“magmatic hierarchy”, such that $$M_1(A)=LO(A,\preccurlyeq )$$, $$M_{\alpha +1}(A)=LO(M_\alpha (A),\subseteq )$$, and $$M_\alpha (A)=\bigcup _{\beta <\alpha }M_\beta (A)$$, for a limit ordinal $$\alpha $$. For every $$\alpha \ge 1$$, $$M_\alpha (A)\subseteq V_\alpha (A)$$, where $$V_\alpha (A)$$ are the levels of the universe V(A) of $$\textrm{ZFA}$$. The class $$M(A)=\bigcup _{\alpha \ge 1}M_\alpha (A)$$ is the “magmatic universe above A.” The axioms of Powerset and Union (the latter in a restricted version) turn out to be true in $$\langle M(A),\in \rangle $$. Besides it is shown that three of the five principles about magmas that Castoriadis proposed in his writings (mildly modified and adapted to the needs of formalization), $$M2^*$$, $$M3^*$$ and $$M5^*$$, are true of M(A). A selection of excerpts from these writings, in which the concept of magma was first introduced and elaborated, is presented in the Introduction. (shrink)

The history of sonar technology provides a fascinating case study for philosophers of science. During the first and second World Wars, sonar technology was primarily associated with activity on the part of the sonar technicians and researchers. Usually this activity is concerned with creation of sound waves under water, as in the classic “ping and echo”. The last fifteen years have seen a shift toward passive, ambient noise “acoustic daylight imaging” sonar. Along with this shift a new relationship (...) has begun between sonar technicians and environmental ethics. I have found a significant shift in the values, and the environmental ethics, of the underwater community by looking closely at the term “noise” as it has been conceptualized and reconceptualized in the history of sonar technology. To illustrate my view, I will include three specific sets of information: 1) a discussion of the 2003 debate regarding underwater active low- frequency sonar and its impact on marine life; 2) a review of the history of sonar technology in diagrams, abstracts, and artifacts; 3) the latest news from February 2004 on how the military and the acoustic daylight imaging passive sonar community has responded to the current debates.

Against the opinion that DNA as program is not sufficiently explanatory, we maintain that the cellular machinery is entirely computational, and we identify the crucial notion of the interpreter that expresses the gene with the minimal gene set. Epigenetics research does not so much need paradigm shifts as the unraveling of an exceedingly complex computational machine.

This paper attempts to examine the paradigm shift in ASEAN from a state-based to a people-based organization. We argue that by adopting a people-based organization, ASEAN now enters an era of Neo-Communitarianism replacing the Old Communitarianism of the old generation of ASEAN. By using communitarian perspectives, we look at the continuities and changes in ASEAN with regard to how it deals with issues involving their members. Three important issues namely the debates on intervention principle; the adoption of the three (...) pillars of the ASEAN Community; and the inclusion of human rights are seen as the signposts where ASEAN departs from their Old to a Neo-Communitarianism. Although there have been a lot of challenges to the realization of the people-based organization, we see that the dynamics of debates and the active participation of the community in the debates show good prospects for the new paradigm to realize. In this paper, we use debate on the formation of ASEAN Intergovernmental Commission on Human Rights (ICHR), to show the involvements of people in setting the agendas for the future ASEAN. (shrink)

With a global commitment to scaling up AIDS care and treatment in resource-poor settings for some of the most HIV-affected countries in Africa, availability of antiretroviral treatment is no longer the principal obstacle to expanding access to treatment. A shortage of trained healthcare personnel to initiate treatment and manage patients represents a more challenging barrier to offering life-saving treatment to all patients in need. Physician-centered treatment policies accentuate this challenge. Despite evidence that task shifting for nurse-centered AIDS patient care is (...) effective and can alleviate severe physician shortages that currently obstruct treatment scale-up, political commitment and policy action to support task shifting models of care has been slow to absent. In this paper we review the evidence in support of task shifting for AIDS treatment in Africa and argue that continued policy inaction amounts to unwarranted healthcare rationing and as such is ethically untenable.

Given a subject so imbued with contention and conflicting theoretical stances, it is remarkable that automated instruments ever came to replace the human eye as sensitive arbiters of color specification. Yet, dramatic shifts in assumptions and practice did occur in the first half of the twentieth century. How and why was confidence transferred from careful observers to mechanized devices when the property being measured – color – had become so closely identified with human physiology and psychology? A fertile perspective on (...) the problem is via the history of science and technology, paying particular attention to social groups and disciplinary identity to determine how those factors affected their communities’ cognitive territory. There were both common and discordant threads motivating the various technical groups that took on the problems of measuring light and color from the late nineteenth century onwards, and leading them towards the development of appropriate instruments for themselves. The transition from visual to photoelectric methods could be portrayed as a natural evolution, replacing the eye by an alternative roviding more sensitivity and convenience – indeed, this is the conventional positivist view propounded by technical histories. However, the adoption of new measurement technologies seldom is simple, and frequently has a significant cultural component. Beneath this slide towards automation lay a raft of implicit assumptions about objectivity, the nature of the observer, the role of instruments, and the trade-offs between standardization and descriptive power. While espousing rational arguments for a physical detector of color, its proponents weighted their views with tacit considerations. The reassignment of trust from the eye to automated instruments was influenced as much by the historical context as by intellectual factors. I will argue that several distinct aspects were involved, which include the reductive view of color provided by the trichromatic theory; the impetus provided by its association with photometry; the expanding mood for a quantitative and objective approach to scientific observation; and, the pressures for commercial standardization. As suggested by these factors, there was another shift of authority at play: from one technical specialism to another. The regularization of color involved appropriation of the subject by a particular set of social interests: communities of physicists and engineers espousing a ‘physicalist’ interpretation, rather than psychologists and physiologists for whom color was conceived as a more complex phenomenon. Moreover, the sources for automated color measurement, and instrumentation for measuring color, were primarily from the industrial sphere rather than from academic science. To understand these shifts, then, this chapter explores differing views of the importance of observers, machines and automation. (shrink)
