Over the years, Katie Cannon's students referred to her work in progress as "Katie's canon." Not only does this book represent the canon of Cannon's best work; the book itself directly addresses the issues of canon formation and canon reformation. Cannon canonizes a literary tradition and directly addresses both oppression and liberation of African American women. Now in an expanded 25th-anniversary edition, Katie's Canon still packs firepower.

The ecosystem services argument is a highly publicised instrumental argument for protecting biodiversity. I develop a new objection to this argument based on the lack of a causal connection from global species losses to local ecosystem changes. I survey some alternative formulations of services arguments, including ones incorporating option value or a precautionary principle, and show that they do not fare much better than the standard version. I conclude that environmental thinkers should rely less on ecosystem services as a means (...) to defend biodiversity, and that attention should be focused on additional types of value which might be attributed to global biodiversity.

While the fundamental laws of physics are time-reversal invariant, most macroscopic processes are irreversible. Given that the fundamental laws are taken to underpin all other processes, how can the fundamental time-symmetry be reconciled with the asymmetry manifest elsewhere? In statistical mechanics, progress can be made with this question. What I dub the ‘Zwanzig–Zeh–Wallace framework’ can be used to construct the irreversible equations of SM from the underlying microdynamics. Yet this framework uses coarse-graining, a procedure that has faced much criticism. I (...) focus on two objections in the literature: claims that coarse-graining makes time-asymmetry ‘illusory’ and ‘anthropocentric’. I argue that these objections arise from an unsatisfactory justification of coarse-graining prevalent in the literature, rather than from coarse-graining itself. This justification relies on the idea of measurement imprecision. By considering the role that abstraction and autonomy play, I provide an alternative justification and offer replies to the illusory and anthropocentric objections. Finally, I consider the broader consequences of this alternative justification: the connection to debates about inter-theoretic reduction and the implication that the time-asymmetry in SM is weakly emergent. 1Introduction 1.1Prospectus2The Zwanzig–Zeh–Wallace Framework3Why Does This Method Work? 3.1The special conditions account3.2When is a density forwards-compatible?4Anthropocentrism and Illusion: Two Objections 4.1The two objections in more detail4.2Against the justification by measurement imprecision5An Alternative Justification 5.1Abstraction and autonomy5.2An illustration: the Game of Life6Reply to Illusory7Reply to Anthropocentric8The Wider Landscape: Concluding Remarks 8.1Inter-theoretic relations8.2The nature of irreversibility.

Recently in environmental ethics some theorists have advocated narrative accounts of value, according to which the value of environmental goods is given by the role that they play in our narratives. I first sketch the basic theoretical features of a narrative accounts of value and then go on to raise some problems for such views. I claim that they require an evaluative standard in order to distinguish the valuable from the merely valued and that the project of constructing such a (...) standard faces significant problems. I conclude by questioning whether narrative accounts of value really offer advantages over other pluralistic and context-sensitive accounts of value. (shrink)

This paper considers a key point of contention between classical and Bayesian statistics that is brought to the fore when examining so-called ‘persistent experimenters’—the issue of stopping rules, or more accurately, outcome spaces, and their influence on statistical analysis. First, a working definition of classical and Bayesian statistical tests is given, which makes clear that (1) once an experimental outcome is recorded, other possible outcomes matter only for classical inference, and (2) full outcome spaces are nevertheless relevant to both the (...) classical and Bayesian approaches, when it comes to planning/choosing a test. The latter point is shown to have important repercussions. Here we argue that it undermines what Bayesians may admit to be a compelling argument against their approach—the Bayesian indifference to persistent experimenters and their optional stopping rules. We acknowledge the prima facie appeal of the pro-classical ‘optional stopping intuition’, even for those who ordinarily have Bayesian sympathies. The final section of the paper, however, provides three error theories that may assist a Bayesian in explaining away the apparent anomaly in their reasoning. (shrink)

Background: Exploring the concept of ethical competence in the context of healthcare is essential as it pertains to better quality of care. The concept still lacks a comprehensive definition covering the aspects of ethical expertise, ethical knowledge and action of a health professional. Objective: This article aims to report an analysis of the concept of ethical competence. Method: A modified strategy suggested by Walker and Avant was used to analyse the concept. Results: As a result, the concept of ethical competence (...) can be defined in terms of character strength, ethical awareness, moral judgement skills and willingness to do good. Virtuous professional, experience of a professional, human communication, ethical knowledge and supporting surroundings in the organisation can be seen as prerequisites for ethical competence. Ethical competence results in the best possible solutions for the patient, reduced moral distress at work and development and democratisation of society. Conclusion: The results of the analysis establish a basis for an instrument to evaluate health professionals’ ethical competence. It will guide educators, as well as managers in healthcare, to support the development of ethical conduct in healthcare. (shrink)

Internet protocol development is a social process, and resulting protocols are shaped by their developers’ politics and values. This article argues that the work of protocol development poses barriers to developers’ reflection upon values and politics in protocol design. A participant observation of a team developing internet protocols revealed that difficulties defining the stakeholders in an infrastructure and tensions between local and global viewpoints both complicated values reflection. Further, Internet architects tended to equate a core value of interoperability with values (...) neutrality. The article describes how particular work practices within infrastructure development overcame these challenges by engaging developers in praxis: situated, lived experience of the social nature of technology.

There is a strong impetus in international agricultural development to close ‘gender gaps’ in agricultural productivity. The goal of empowering women is often framed as the solution to closing these gaps, stimulating the proliferation of new indicators and instruments for the targeting, measurement, and tracking of programmatic goals in research for agricultural development. Despite these advances, current measurements and indices remain too simplified in terms of unit and scope of analysis, as well as being fundamentally flawed in how they aim (...) to capture the relevance of ‘gender’ in diverse local contexts. We propose that the impulse to apply exogenously defined and weakly validated ‘women’s empowerment’ measures to diverse local contexts risks prioritizing practical expedience over scientific accuracy and societal relevance. Furthermore, the application of such measures risks creating the impression that programmatic “gender targets” are being achieved, while simultaneously undermining substantive gender transformative goals. The authors conclude that a different methodological approach grounded in participatory and qualitative methods is needed to create more meaningful metrics for assessing progress towards women’s empowerment.

Richard Rudner famously argues that the communication of scientific advice to policy makers involves ethical value judgments. His argument has, however, been rightly criticized. This article revives Rudner’s conclusion, by strengthening both his lines of argument: we generalize his initial assumption regarding the form in which scientists must communicate their results and complete his ‘backup’ argument by appealing to the difference between private and public decisions. Our conclusion that science advisors must, for deep-seated pragmatic reasons, make value judgments is further (...) bolstered by reflections on how the scientific contribution to policy is far less straightforward than the Rudner-style model suggests.

For sets A,Bsubset of or equal toω, we say that A is bounded Turing reducible to reducible to) B if there is a Turing functional, Φ say, with a computable bound of oracle query bits such that A is computed by Φ equipped with an oracle B, written image. Let image be the structure of the c.e. bT-degrees, (...) the c.e. degrees under the bounded Turing reductions. In this paper we study the continuity properties in image. We show that for any c.e. bT-degree image, there is a c.e. bT-degree image such that for any c.e. bT-degree image, image if and only if image. We prove that the analog of the Seetapun local noncappability theorem from the c.e. Turing degrees also holds in image. This theorem demonstrates that every image is noncappable with any nontrivial degree below some image. (shrink)

In this paper, we present a particular role for abductive reasoning in law by applying it in the context of an argumentation scheme for practical reasoning. We present a particular scheme, based on an established scheme for practical reasoning, that can be used to reason abductively about how an agent might have acted to reach a particular scenario, and the motivations for doing so. Plausibility here depends on a satisfactory explanation of why this particular agent followed these motivations in the (...) particular situation. The scheme is given a formal grounding in terms of action-based alternating transition systems and we illustrate the approach with a running legal example.

Doug Walton, who died in January 2020, was a prolific author whose work in informal logic and argumentation had a profound influence on Artificial Intelligence, including Artificial Intelligence and Law.

There is growing consensus that teaching computer ethics is important, but there is little consensus on how to do so. One unmet challenge is increasing the capacity of computing students to make decisions about the ethical challenges embedded in their technical work. This paper reports on the design, testing, and evaluation of an educational simulation to meet this challenge. The privacy by design simulation enables more relevant and effective computer ethics education by letting students experience and make decisions about common (...) ethical challenges encountered in real-world work environments. This paper describes the process of incorporating empirical observations of ethical questions in computing into an online simulation and an in-person board game. We employed theValues at Playframework to transform empirical observations of design into a playable educational experience. First, we conducted qualitative research to discover when and how values levers—practices that encourage values discussions during technology development—occur during the design of new mobile applications. We then translated these findings into gameplay elements, including the goals, roles, and elements of surprise incorporated into a simulation. We ran the online simulation in five undergraduate computer and information science classes. Based on this experience, we created a more accessible board game, which we tested in two undergraduate classes and two professional workshops. We evaluated the effectiveness of both the online simulation and the board game using two methods: a pre/post-test of moral sensitivity based on the Defining Issues Test, and a questionnaire evaluating student experience. We found that converting real-world ethical challenges into a playable simulation increased student’s reported interest in ethical issues in technology, and that students identified the role-playing activity as relevant to their technical coursework. This demonstrates that roleplaying can emphasize ethical decision-making as a relevant component of technical work. (shrink)

A few years ago, it was common for philosophers to begin inquiry into hope by noting that the subject has received little attention in the philosophical literature. But our ability to make this claim is quickly coming to an end; hope has been earning increasing recognition in the discipline, with philosophers exploring important questions related to the nature of hope, what makes hope rational, and how hope is connected to human wellbeing and agency. Despite this recent interest, however, there remains (...) very little discussion of the social and political dimensions of hope. My aim in this paper is to demonstrate the importance of a feminist perspective in bringing these dimensions into fuller view. I argue that feminist insights into the relational nature of the self, which call attention to where selves are socially situated in relation to others, enable a richer understanding of the nature and value of hope.

The technical details of Internet architecture affect social debates about privacy and autonomy, intellectual property, cybersecurity, and the basic performance and reliability of Internet services. This paper explores one method for practicing anticipatory ethics in order to understand how a new infrastructure for the Internet might impact these social debates. This paper systematically examines values expressed by an Internet architecture engineering team—the Named Data Networking project—based on data gathered from publications and internal documents. Networking engineers making technical choices also weigh (...) non-technical values when working on Internet infrastructure. Analysis of the team’s documents reveals both values invoked in response to technical constraints and possibilities, such as efficiency and dynamism, as well as values, including privacy, security and anonymity, which stem from a concern for personal liberties. More peripheral communitarian values espoused by the engineers include democratization and trust. The paper considers the contextual and social origins of these values, and then uses them as a method of practicing anticipatory ethics: considering the impact such priorities may have on a future Internet.

This study identified and described ethical problems encountered by physiotherapists in their practice and physiotherapists’ moral sensitivity in ethical situations. A questionnaire-based survey was constructed to identify ethical problems, and the Moral Sensitivity Questionnaire Revised version was used to measure moral sensitivity. Physiotherapists (n = 116) working in public health services responded to the questionnaire. Based on the results, most of the physiotherapists encounter ethical problems weekly. They concern mainly financial considerations, equality and justice, professionalism, unethical conduct of physiotherapists or (...) other professions and patients’ self-determination. The dimension of moral strength was emphasised in physiotherapists’ self-evaluations of their moral sensitivity. As a conclusion, ethical problems do occur not only at individual level but also at organisational and society level. Physiotherapists seem to have moral strength for speaking on behalf of the patient. Scarce resources make them feel insufficient but much could still be done to provide quality care in co-operation with other health-care professionals. (shrink)

In what sense are the special sciences autonomous of fundamental physics? Autonomy is an enduring theme in discussions of the relationship between the special sciences and fundamental physics or, more generally, between higher and lower-level facts. Discussion of ‘autonomy’ often fails to recognise that autonomy admits of degrees; consequently, autonomy is either taken to require full independence, or risk relegation to mere apparent autonomy. In addition, the definition of autonomy used by Fodor, the most famous proponent of the autonomy of (...) the special sciences, has been robustly criticised by Loewer. In this paper I develop a new account of autonomy following Woodward which I dub ‘generalised autonomy’ since it unifies dynamical, causal and nomic autonomy. Autonomy, on this account, can be partial: some lower-level details matter while others do not. To summarise: whilst the detailed lower level is unconditionally relevant, conditionalising on the higher-level facts renders some lower-level details irrelevant. The macrodependencies that the higher-level facts enter into — be they dynamical, causal or nomic — screen off the underlying microdetails. This account helps resolve an explanatory puzzle: if the lower-level facts in some way underpin the higher-level facts, why don’t the lower-level details matter more for the day-to-day practice of the special sciences? The answer will be: the facts uncovered by the special sciences are autonomous in my sense, and so practitioners of these special sciences need not study more fundamental sciences, since these underlying facts are genuinely irrelevant.

In this paper we consider persuasion in the context of practical reasoning, and discuss the problems associated with construing reasoning about actions in a manner similar to reasoning about beliefs. We propose a perspective on practical reasoning as presumptive justification of a course of action, along with critical questions of this justification, building on the account of Walton. From this perspective, we articulate an interaction protocol, which we call PARMA, for dialogues over proposed actions based on this theory. We outline (...) an axiomatic semantics for the PARMA Protocol, and discuss two implementations which use this protocol to mediate a discussion between humans. We then show how our proposal can be made computational within the framework of agents based on the Belief-Desire-Intention model, and illustrate this proposal with an example debate within a multi agent system.

In this paper we describe the impact that Walton’s conception of argumentation schemes had on AI and Law research. We will discuss developments in argumentation in AI and Law before Walton’s schemes became known in that community, and the issues that were current in that work. We will then show how Walton’s schemes provided a means of addressing all of those issues, and so supplied a unifying perspective from which to view argumentation in AI and Law.

Theories of emotion have often maintained artificial boundaries: for instance, that cognition and emotion are separable, and that an emotion concept is separable from the emotional events that comprise its category (e.g. “fear” is distinct from instances of fear). Over the past several years, research has dissolved these artificial boundaries, suggesting instead that conceptual construction is a domain-general process—a process by which the brain makes meaning of the world. The brain constructs emotion concepts, but also cognitions and perceptions, all in (...) the service of guiding action. In this view, concepts are multimodal constructions, dynamically prepared from a set of highly variable instances. This approach obviates old questions (e.g. how does cognition regulate emotion?) but generates new ones (e.g. how does a brain learn emotion concepts?). In this paper, we review this constructionist, predictive coding account of emotion, considering its implications for health and well-being, culture and development. (shrink)

In this paper we describe an approach to practical reasoning, reasoning about what it is best for a particular agent to do in a given situation, based on presumptive justifications of action through the instantiation of an argument scheme, which is then subject to examination through a series of critical questions. We identify three particular aspects of practical reasoning which distinguish it from theoretical reasoning. We next provide an argument scheme and an associated set of critical questions which is able (...) to capture these features. In order that both the argument scheme and the critical questions can be given precise interpretations we use the semantic structure of an Action-Based Alternating Transition System as the basis for their definition. We then work through a detailed example to show how this approach to practical reasoning can be applied to a problem solving situation, and briefly describe some other previous applications of the general approach. In a second example we relate our account to the social laws paradigm for co-ordinating multi-agent systems. The contribution of the paper is to provide firm foundations for an approach to practical reasoning based on presumptive argument in terms of a well-known model for representing the effects of actions of a group of agents.

Governments and other groups interested in the views of citizens require the means to present justifications of proposed actions, and the means to solicit public opinion concerning these justifications. Although Internet technologies provide the means for such dialogues, system designers usually face a choice between allowing unstructured dialogues, through, for example, bulletin boards, or requiring citizens to acquire a knowledge of some argumentation schema or theory, as in, for example, ZENO. Both of these options present usability problems. In this paper, (...) we describe an implemented system called PARMENIDES which allows structured argument over a proposed course of action, without requiring knowledge of the underlying argumentation theory.

An effectively closed set, or ${\Pi^{0}_{1}}$ class, may viewed as the set of infinite paths through a computable tree. A numbering, or enumeration, is a map from ω onto a countable collection of objects. One numbering is reducible to another if equality holds after the second is composed with a computable function. Many commonly used numberings of ${\Pi^{0}_{1}}$ classes are shown to be mutually reducible via a computable permutation. Computable injective numberings are given for the family of ${\Pi^{0}_{1}}$ classes and (...) for the subclasses of decidable and of homogeneous ${\Pi^{0}_{1}}$ classes. However no computable numberings exist for small or thin classes. No computable numbering of trees exists that includes all computable trees without dead ends. (shrink)

In these lines Ovid introduces Althaea's debate whether or not to kill her son Meleager by burning the brand which was his life, because he had killed her two brothers during the Calydonian boar hunt. A. S. Hollis says of line 476 that it contains ‘a forced and almost pointless word-play’. If sanguis is taken in its primary meaning, ‘blood’, this condemnation is quite justified. However, if one takes into account a secondary sense, the word-play acquires more strength. This sense (...) is that of ‘offspring’ or ‘descendant’. Examples of this usage include Virgil, Aeneid 6.835 ‘sanguis meus’ , Horace, Carmen Saeculare 50 ‘clarus Anchisae Venerisque sanguis’ , Odes 3.27.65 ‘regius sanguis’ , and, in the Metamorphoses itself ‘pro…meo veni supplex tibi, Iuppiter, …sanguine’. It may well be that Ovid was intending implications of both meanings in his choice of the word. (shrink)

In this paper, I explore both Kant's and Collingwood's accounts of themind-body problem. I discuss how both philosophers think that this problem arises and how it can be resolved. I start by discussing the similarities between the attempts of the two philosophers at solving philosophical problems through analysing the conceptual structures that make experience possible. I then turn to the differences between the views of the two philosophers, paying particular attention to Kant's claims that a combination of a natural (so-called (...) 'transcendental') illusion and commitment to a faulty philosophical framework (transcendental realism) give rise to philosophical problems such as the mind-body problem. I argue, ultimately, that Kant's account is more compelling than Collingwood's. This is because Collingwood's account can only explain the mind-body problem as arising because certain concepts conflict with each other and compete as explanations of the same phenomena. Kant's account, on the other hand, states that the problem arises as a result of both an inevitable illusion and a misapplication of concepts. Both philosophers claim that the problem is perennial but Kant's reason for claiming this is more convincing. (shrink)

pSara Ahmed’s emWillful Subjects/em develops an account of willfulness as a site of simultaneous oppression and resistance: a diagnosis attributed to particular (not-quite-)subjects and to modes of behavior that are thereby diminished, pathologized, and controlled, and a “diagnosis” that may be positively affirmed as a way of living and doing otherwise. This essay puts Ahmed’s work on willfulness in conversation with María Lugones’ decolonial feminism, particularly her theory of active subjectivity. With Lugones, we offer, one can better understand the resistant (...) potential of willfulness, not simply as the willful subject possessing an oppositional “will of her own” (which risks reinscribing a unitary notion of the self), but rather, as exercising a different kind of subjectivity altogether—one that relies on multiplicity and arises through relationships across non-dominant difference. Extending the connections that Ahmed herself draws between willfulness and “madness,” we further explore the willful elements in experiences relating to mental illness and cognitive disability, categories of experience that we understand to be important (and undertheorized) aspects of what Aníbal Quijano has termed “the coloniality of power.”/p.

In this article, I defend a conception of bitterness as a moral emotion and offer an evaluative framework for assessing when instances of bitterness are morally justified. I argue that bitterness is a form of unresolved anger involving a loss of hope that an injustice or other moral wrong will be sufficiently acknowledged and addressed. Orienting the discussion around instances of bitterness in response to social and political injustices, I argue that bitterness is sometimes morally justified even if it is (...) ultimately undesirable to bear. I then suggest that focusing only on the harms and risks of bitterness can distract from its positive role as a moral reminder about a past or persistent injustice, indicating that there is still moral and often political work left to do. Finally, I address the concern that bearing bitterness may lead to despair and inaction. I respond by arguing that moral agents can and do persist in their moral and political struggles with bitterness, and without hope that their efforts will be successful. (shrink)

The search for the statistical mechanical underpinning of thermodynamic irreversibility has so far focussed on the spontaneous approach to equilibrium. But this is the search for the underpinning of what Brown and Uffink have dubbed the ‘minus first law’ of thermodynamics. In contrast, the second law tells us that certain interventions on equilibrium states render the initial state ‘irrecoverable’. In this article, I discuss the unusual nature of processes in thermodynamics, and the type of irreversibility that the second law embodies. (...) I then search for the microscopic underpinning or statistical mechanical ‘reductive basis’ of the second law of thermodynamics by taking a functionalist strategy. First, I outline the functional role of the thermodynamic entropy: for a thermally isolated system, the thermodynamic entropy is constant in quasi-static processes, but increasing in non-quasi-static processes. I then search for the statistical mechanical quantity that plays this role—rather than the role of the traditional ‘holy grail’ as described by Callender. I argue that in statistical mechanics, the Gibbs entropy plays this role. (shrink)

Privacy is a critical challenge for corporate social responsibility in the mobile device ecosystem. Mobile application firms can collect granular and largely unregulated data about their consumers, and must make ethical decisions about how and whether to collect, store, and share these data. This paper conducts a discourse analysis of mobile application developer forums to discover when and how privacy conversations, as a representative of larger ethical debates, arise during development. It finds that online forums can be useful spaces for (...) ethical deliberations, as developers use these spaces to define, discuss, and justify their values. It also discovers that ethical discussions in mobile development are prompted by work practices which vary considerably between iOS and Android, today’s two major mobile platforms. For educators, regulators, and managers interested in encouraging more ethical discussion and deliberation in mobile development, these work practices provide a valuable point of entry. But while the triggers for privacy conversations are quite different between platforms, ultimately the justifications for privacy are similar. Developers for both platforms use moral and cautionary tales, moral evaluation, and instrumental and technical rationalization to justify and legitimize privacy as a value in mobile development. Understanding these three forms of justification for privacy is useful to educators, regulators, and managers who wish to promote ethical practices in mobile development. (shrink)

I focus my discussion on the well-known Ellsberg paradox. I find good normative reasons for incorporating non-precise belief, as represented by sets of probabilities, in an Ellsberg decision model. This amounts to forgoing the completeness axiom of expected utility theory. Provided that probability sets are interpreted as genuinely indeterminate belief, such a model can moreover make the “Ellsberg choices” rationally permissible. Without some further element to the story, however, the model does not explain how an agent may come to have (...) unique preferences for each of the Ellsberg options. Levi holds that the extra element amounts to innocuous secondary “risk” or security considerations that are used to break ties when more than one option is rationally permissible. While I think a lexical choice rule of this kind is very plausible, I argue that it involves a greater break with xpected utility theory than mere violation of the ordering axiom. (shrink)

Biocentric egalitarianism is the view that all living things share an equal fundamental moral status qua living things. In light of the well-known problems with past philosophical attempts to argue for this position, this paper proposes a way biocentric egalitarian claims might be understood and possibly vindicated. Relying on frameworks developed in recent discussions of the “basis of equality” in human-centered ethics, the paper argues that thinking of egalitarian claims as justified by (rather than as justifying) social ideals provides the (...) best way of understanding the basis of biocentric egalitarian claims in environmental ethics. The paper first reviews arguments for biocentric egalitarianism and their central flaws and proceeds to survey different models for justifying egalitarian claims among humans. The paper argues the Social Ideal approach to justification is the one most likely to be helpful to biocentric egalitarians. (shrink)

When once-successful physical theories are abandoned, common wisdom has it that their characteristic theoretical entities are abandoned with them: examples include phlogiston, light rays, Newtonian forces, Euclidean space. But sometimes a theory sees ongoing use, despite being superseded. What should scientific realists say about the characteristic entities of the theories in such cases? The standard answer is that these ‘theoretical relicts’ are merely useful fictions. In this paper we offer a different answer. We start by distinguishing horizontal reduction (in which (...) a superseded theory approximates the successor theory) from vertical reduction (in which a higher-level theory abstracts away from the lower-level theory, but nonetheless can be constructed from it); these are usually regarded as having different ontological consequences. We describe a ‘verticalization’ procedure which transforms horizontal reductions into vertical reductions. The resulting verticalized theories are abstractions rather than approximations, with restricted domains. We identify a sense in which the higher-level theory describes distinct subject matters from the lower-level theory, enabling in certain cases the higher-level theory to retain distinctive explanatory power even in the presence of reduction. We suggest that theoretical entities from superseded theories should be retained in a scientific realist worldview just when, reinterpreted as higher-level abstractions, those theories and their characteristic entities continue to perform distinctive explanatory work in providing the best explanation for less-fundamental phenomena of interest. In slogan form: a good relict is an emergent relict. (shrink)

This article draws on the ethnography of Aboriginal Australia to argue that perceptual openness, extending from waking life into dreaming experience, provides an important cognitive framework for the apprehension of dreamt experience in these contexts. I argue that this perceptual openness is analogous to the “openness to experience” described as a personality trait that had been linked with dream recall frequency. An implication of identifying perceptual openness at a cultural rather than at an individual level is two-fold. It provides an (...) example of the ways in which cultural differences affect perception, indicative of cognitive diversity; and, given the relationship between dreams and creativity suggested anecdotally and through research, a cultural orientation toward perceptual openness is also likely to have implications for the realization of creativity that occurs through dreams. Such creativity though cannot be separated from the relational context in which such dreamt material is elaborated and understood. (shrink)

In celebrating the epistemological reform and empowerment of non-white peoples in the academy, we propose a manifesto that seeks to dislodge the complacencies within Sikh Studies and within Sikh communities, and invite non-Sikhs to engage with radical Sikhi social justice. By dwelling at feminist intersections of postcolonial studies, decolonial studies, and decolonization studies, we are inspired to share the radical possibilities of Sikh Studies, and we also urge Sikh Studies and Sikh people to inhabit an explicit political orientation of insurrection (...) and subversion. Importantly, such a feminist decolonial orientation may well hold promise for other fields of study on the margins as well. In particular, we foreground eight points of action: gendering Sikh Studies; de-policing intimate desire and the diversity of relationships; disrupting Eurocentric knowledge production; de-territorializing diasporas; challenging caste politics; disrupting Islamophobia; undoing our roles in contemporary colonialisms; and fostering care and responsibility for the nonhuman world. In this manifesto we hope to develop interdisciplinary connections, critical interventions, and broader alliances to cultivate debates and action that both challenge tradition and participate within broader political campaigns for social justice.

This article explores the experiences of Latina lesbian migrants living in the United States. Drawing on in-depth interviews with 15 Latina lesbian migrants, I argue that Latinas' sexual, racial, and class identities are continuously shifting as the process of migration repositions them in a new system of racial inequality. Their sexual identities are altered as migrants often silence their lesbian existence when negotiating relationships with families of origin. Lesbianas establish borderland spaces for themselves where they gain sexual autonomy but where (...) their identities are in flux. These spaces are “imagined communities” because while lesbianas envision them to provide solidarity, in practice the borderlands are riddled with inequalities and tensions. Despite this, the borderlands allow lesbianas to develop a mestiza consciousness. (shrink)
