In this paper, we analyse how GPS-based navigation systems are transforming some of our intellectual virtues and then suggest two strategies to improve our practices regarding the use of such epistemic tools. We start by outlining the two main approaches in virtue epistemology, namely virtue reliabilism and virtue responsibilism. We then discuss how navigation systems can undermine five epistemic virtues, namely memory, perception, attention, intellectual autonomy, and intellectual carefulness. We end by considering two possible interlinked ways of trying (...) to remedy this situation: [i] redesigning the epistemic tool to improve the epistemic virtues of memory, perception, and attention; and [ii] the cultivation of cognitive diligence for wayfinding tasks scaffolding intellectual autonomy and carefulness.

A central question in neuroscience and psychology is how the mammalian brain represents the outside world and enables interaction with it. Significant progress on this question has been made in the domain of spatial cognition, where a consistent network of brain regions that represent external space has been identified in both humans and rodents. In rodents, much of the work to date has been done in situations where the animal is free to move about naturally. By contrast, the majority of (...) work carried out to date in humans is static, due to limitations imposed by traditional laboratory based imaging techniques. In recent years, significant progress has been made in bridging the gap between animal and human work by employing Virtual Reality (VR) technology to simulate aspects of real-world navigation. Despite this progress, the VR studies often fail to fully simulate important aspects of real-world navigation, where information derived from self-motion is integrated with representations of environmental features and task goals. In the current review, we provide a brief overview of animal and human imaging work to date, focusing on commonalties and differences in findings across species. Following on from this we discuss VR studies of spatial cognition, outlining limitations and developments, before introducing mobile brain imaging techniques and describe technical challenges and solutions for real-world recording. Finally, we discuss how these advances in mobile brain imaging technology, provide an unprecedented opportunity to illuminate how the brain represents complex multifaceted information during naturalistic navigation.

This study explored spatial navigation alongside several other cognitive abilities that are thought to share common underlying neurocognitive mechanisms (e.g., the capacity for self-projection, scene construction, or mental simulation), and which we hypothesised may be impaired in autism spectrum disorder (ASD). Twenty intellectually high-functioning children with ASD (with a mean age of ~8 years) were compared to 20 sex, age, IQ, and language ability matched typically developing children on a series of tasks to assess spatial navigation, episodic memory, (...) episodic future thinking (also known as episodic foresight or prospection), theory of mind, relational memory, and central coherence. This is the first study to explore these abilities concurrently within the same sample. Spatial navigation was assessed using the “memory island” task, which involves finding objects within a realistic, computer simulated, three-dimensional environment. Episodic memory and episodic future thinking were assessed using a past and future event description task. Theory of mind was assessed using the “animations” task, in which children were asked to describe the interactions between two animated triangles. Relational memory was assessed using a recognition task involving memory for items (line drawings), patterned backgrounds, or combinations of items and backgrounds. Central coherence was assessed by exploring differences in performance across segmented and unsegmented versions of block design. Children with ASD were found to show impairments in spatial navigation, episodic memory, episodic future thinking, and central coherence, but not theory of mind or relational memory. Among children with ASD, spatial navigation was found to be significantly negatively related to number of repetitive behaviours. In other words, children who showed more repetitive behaviours showed poorer spatial navigation. The theoretical and practical implications of the results are discussed. (shrink)

Families and clinicians approaching a child’s death in the paediatric intensive care unit (PICU) frequently encounter questions surrounding medical decision-making at the end of life (EOL), including defining what is in the child’s best interest, finding an optimal balance of benefit over harm, and sometimes addressing potential futility and moral distress. The best interest standard (BIS) is often marshalled by clinicians to help navigate these dilemmas and focuses on a clinician’s primary ethical duty to the paediatric patient. This approach does (...) not consider a clinician’s potential duty to the patient’s family. This paper argues that when a child is dying in the PICU, the physician has a duty to serve both the patient and the family, and that in some circumstances, the duty to serve the family becomes as important as that owed to the child. We detail the limitations of the BIS in paediatric EOL care and propose the relational potential standard as an additional ethical framework to guide our decisions. (shrink)

Through the personal stories of managers running global business, this book takes an inside look into the dilemmas of managers who are asked to make profits ethically according to the dictates of their company's ethics code. It examines what companies `think" they are doing to help managers in those situations and how those managers are actually affected. Thanks to the boost from the 1991 Sentencing Guidelines which minimizes penalties for companies with ethics codes caught in ethical wrongdoing, more than 85% (...) of US companies and two thirds of all Canadian companies and half of all European companies now have Codes of Ethics. Yet, over and over, we hear of stories of personal dilemmas and conflicts experienced by individual managers navigating those business waters in other cultures. "Eileen Morgan does an excellent job of mapping the course for navigating the previously uncharted global ethical waters. By identifying best practices, she leads the reader on a journey from Surviving, to Understanding to Knowing the ethical issues that frequently confront international business people. This is a must read for anyone who wants to successfully compete in world markets." -Michael J. Litwin, Executive Vice President, Chief Credit Officer, Heller Financial, Inc. "Eileen Morgan has combined the pragmatic concerns of the individual manager with the moral concerns that come from personal-life history, cultural roots, and corporate ethical culture …This book focuses on the constructive task of formulating and using an "ethical map," and is sure to be a tonic to conscientious managers who want to navigate cross-cultural commerce with integrity. It has done a superb job of creating order out of the complexity of cross-cultural moral experience by insisting that the complexity must be honored and appropriated rather than ignored or suppressed." -Dr. Richard Beauchamp, Professor of Ethics, Christopher Newport University "In this groundbreaking book, Eileen Morgan has provided scores of real-life examples and developed a framework for approaching ethical leadership in international business. This is mandatory reading for anyone involved in global management today...This is an important book on an important subject." -Stephen H. Rhinesmith, Ph.D. Author, A Manager's Guide to Globalization "Eileen Morgan provides us with a much needed roadmap for how to walk the path of ethical leadership with practical feet. She reminds us that ethical decision-making is a critical aspect of every day leadership, and that we can all choose to be 'ethical pioneers' in our companies and our communities. Every leader engaged in global business can benefit from the lessons and stories included in this book." -Christi A. Olson, Ph.D. Chair, Telecommunications Management Department, Golden Gate University "Eileen Morgan's thoughtful analysis of 'ethical capital' should be read by anyone who does business in a global environment…Morgan's book presents the issue clearly, comprehensively and compellingly, demonstrating that ethics is an indispensable aspect of individual leadership and organizational credibility. …It provides a clear roadmap for business leaders who need to communicate their commitment to integrity and accountability to their employees, their partners, and their customer, making their 'ethical capital' one of their most valuable assets." -Nell Minnow, Principal, Lens, The Corporate Governance Investors "Eileen Morgan gives excellent insight into ethical practices. She focuses on business but her insights have general application. This book also describes differences in ethical interpretation that can arise between diverse cultures.

Ethics review committees have become a common institution in English-speaking research communities, and are now increasingly being adopted in a variety of research environments. In light of existing debates on the aptness of ethics review boards for assessing research work in the social sciences, this article investigates the ways in which researchers navigate issues of research ethics in the absence of a formal review procedure or of an ethics review board. Through the analysis of qualitative and quantitative data, the article (...) questions the overall utility of ethics review boards. Highlighting the importance of space for sharing, the authors argue for the development of a new type of structure that takes into account researchers’ ‘ethos of responsibility’ as an adequate ethical compass for research in the social sciences.

Animals navigate through three-dimensional environments, but we argue that the way they encode three-dimensional spatial information is shaped by how they use the vertical component of space. We agree with Jeffery et al. that the representation of three-dimensional space in vertebrates is probably bicoded (with separation of the plane of locomotion and its orthogonal axis), but we believe that their suggestion that the vertical axis is stored (that is, not containing distance or direction metrics usable for novel computations) is unlikely, (...) and as yet unsupported. We describe potential experimental protocols that could clarify these differences in opinion empirically. (shrink)

Exemplars have the power to help people navigate various levels of moral struggle, from the relatively straightforward problem of lacking motivation to the much deeper problem of failing to see the moral realities that surround us. But there are also serious moral risks in the appeal to exemplars: we romanticize them, we make use of them in authoritarian ways, and we tend to forget how our choice of exemplars is conditioned by oppressive cultural formations. I argue that we need to (...) develop a social model of exemplarity, attuned to social contexts of our exemplars themselves as well as the social processes of constructing and appealing to exemplars. More particularly, I argue that we need to develop space for thinking about exemplary groups, not just exemplary individuals, in order to develop the strengths and avoid the weaknesses in exemplarist moral theories.

In recent years, discourses on photography have undergone a transformative shift from a focus on the individual photograph’s connection to memory, pastness, loss, and death towards exploring photographic imagery as shared, networked, and continuously circulating in a ubiquitous present. The general claim for the temporal dimension in this shift is that photography is no longer seen as a mere witness or reservoir of the past but instead points to or participates in an active present. Against this claim, the article argues (...) for broadening the perspective, drawing on resources across C.P. Snow’s “two cultures”—the arts and humanities vs. the natural sciences—to develop a better conception of time and a more varied and useful selection of photographic practices. In this connection, the article provides a reading of Paul Ricoeur’s compound concept of “the third time”, cutting across the two cultures. Drawing on insights from Patrick Maynard and Kelley Wilder, basic premises for photographic practices in the natural sciences are brought into the discussions of the discursive shift from a preoccupation with photography and the past to an interest in photography and the present. The purpose of this paper is to develop a better ground for navigating intricate questions about the relationship between photography and time. (shrink)

The debate about what constitutes the discipline of ethics and who qualifies as an ethics consultant is linked unavoidably to a debate that is potentiated by the reality of a rapidly changing and high-stakes health care consultation marketplace. Who we are and what we can offer to the moral gesture that is medicine is shaped by our fundamental understanding of the place of expert knowledge in the transformation of social reality. The struggle for self-definition is particularly freighted since clinical ethics (...) consultation aspires to be more than academic contemplation. Two recent books (Ethics Consultation by John La Puma and David Schiedermayer and The Health Care Ethics Consultant: A Practical Guide, edited by Francoise Baylis) exemplify the two most popular but most widely divergent positions on these issues. We argue that while useful, neither book addresses fully the particular and distinct role of the professional ethicist. (shrink)

Authors De Marco and colleagues have presented a new model on the concept of invasiveness, redefining both its technical definition and practical implementation.1 While the authors raise valid critiques regarding the discrepancy in definitions, I cannot help but wonder about the purpose of redefining terms for which little confusion, if any, exists? This commentary seeks to scrutinise the rationale supporting the new model in the absence of significant clinical confusion and to explore the implications for clinical practice. Initially, one may (...) notice there is no mention of clinical relevancy, confusion among patients or whether the discrepancy in terms is causing miscommunication. It seems reasonable that some clinical confusion may exist, but so too does a similar imbalance of terms when speaking technically across the specialties; take depression and its definition as a primary example. While I certainly agree with the illustration of non-invasive prenatal testing being compared with venous blood draws as a disparity in terminology, little evidence suggests confusion concerning the nosology.2 The medical community, including both physicians and patients, recognises that the terminology is specifically used within the ….

Navigational performance responds to navigational challenges, and both decline with age in Western populations as older people become less mobile. But mobility does not decline everywhere; Tsimané forager-farmers in Bolivia remain highly mobile throughout adulthood, traveling frequently by foot and dugout canoe for subsistence and social visitation. We, therefore, measured both natural mobility and navigational performance in 305 Tsimané adults, to assess differences with age and to test whether greater mobility was related to better navigational performance across the lifespan. Daily (...) mobility was measured by GPS tracking, regional mobility through interview, navigational performance through pointing accuracy and perspective taking in environmental space, and mental rotation by a computerized task. Although mental rotation and spatial perspective taking declined with age, mobility and pointing accuracy remained high from mid-life through old age. Greater regional mobility was associated with greater accuracy at pointing and perspective taking, suggesting that spatial experience at environmental scales may help maintain navigational performance in later adulthood.

The study of spatial cognition has provided considerable insight into how animals (including humans) navigate on the horizontal plane. However, the real world is three-dimensional, having a complex topography including both horizontal and vertical features, which presents additional challenges for representation and navigation. The present article reviews the emerging behavioral and neurobiological literature on spatial cognition in non-horizontal environments. We suggest that three-dimensional spaces are represented in a quasi-planar fashion, with space in the plane of locomotion being computed separately (...) and represented differently from space in the orthogonal axis bicoded.” We argue that the mammalian spatial representation in surface-travelling animals comprises a mosaic of these locally planar fragments, rather than a fully integrated volumetric map. More generally, this may be true even for species that can move freely in all three dimensions, such as birds and fish. We outline the evidence supporting this view, together with the adaptive advantages of such a scheme. (shrink)

Business leaders frequently face dilemmas, circumstances where whatever course of action they choose, something of important value will be offended. How can an organisation prepare its decision makers for such situations? This article presents a pedagogical approach to dilemma training for business leaders and managers.

The core element in (...) our approach is The Navigation Wheel, a figure used to keep track of relevant decision factors. Feedback from participants indicates that dilemma training has helped them to recognise the ethical dimension of leadership. They respond that the tools and concepts are highly relevant in relation to the challenges that occur in the working environment they return to after leadership training. (shrink)

When business organisations become involved in contributing to and resolving social issues, they enter areas traditionally seen as the purview of governments. In doing so, they begin to take on the expectations and responsibilities of government; they become politicised. This politicisation is a product of business’s success and power and appears largely unavoidable. Adopting Matten & Crane’s (2005a) extended view of corporate citizenship, business organisations’ responsibilities extend to the administration of citizens’ social, civil and political rights. We term these areas (...) where business organisations take over the administration of citizenship rights as the social governance gap. Drawing upon the agenda of Margolis and Walsh (2003), we seek to enhance the understanding of how business navigates its responsibilities within the social governance gap, including its function as a significant actor influencing societal development and wellbeing. We do this through an exploration of Rio Tinto’s involvement in the WA Future Fund. This paper forms part of an introductory scoping case study of the Rio Tinto WA Future fund and its function as one of Rio Tinto’s diverse responses to community development issues in Western Australia.

Classical cognitive science has been characterized by an association with the computational theory of mind. Although this association has produced highly significant results, it has also limited the scope of scientific psychology. In this paper, we analyse the limits of the specific kind of computational model represented by the Chomskian-Fodorian tradition in the study of mind and language. In our opinion, the adhesion to the principle of formality imposed by this specific computational model has motivated the exclusion of consciousness in (...) the reflection on language and, consequently, has led to the inability to account for some aspects of language functioning at the processing level of discourse. The aim of this article is to restore the role of consciousness in discourse comprehension and production processes. Specifically, we argue that the ability to produce and understand discourses is based on individuals’ capacity for navigation in space and time. We will show that the space–time orientation is guaranteed by the projection of the self, which involves a special kind of consciousness. (shrink)

In their upcoming article, Henk Jasper van Gils-Schmidt and Sabine Salloch highlight the supposed responsibilities of healthcare professionals in addressing the global health challenges posed by climate change. They argue that healthcare professionals’ duties to future generations and their ‘climate-related obligations’ have been neglected, primarily due to potential conflicts with other responsibilities, such as providing optimal care to current patients and maintaining patient trust. The authors suggest that these competing obligations should be viewed as part of the multifaceted identities individuals (...) hold, encompassing roles as both physicians and environmentalists, each with normative and competing commitments. They propose that a transformative shift in physicians’ professional ethos, expanding from the predominant focus on individual patients to include obligations towards climate protection, could pave the way for identifying effective mechanisms to address these challenges. While acknowledging the authors’ emphasis on sustainable healthcare practices, we argue that a duty to climate protection as part of healthcare professionals’ identity lacks ethical support. We identify serious concerns that stem from the transformative shift in physicians’ professional ethos, particularly in the authors’ presentation of reasons for action. First, envisaging a stable disposition that compels healthcare professionals to ensure optimal care conditions for both immediate and potential future encounters is unrealistic. Such a scenario would necessitate a nuanced and multifaceted evaluation, weighing …. (shrink)

The mathematical approach to such essentially biological phenomena as perseverative reaching is most welcome. To extend these results and make them more accurate, levels of analysis and neural centers should he distinguished. The navigational nature of sensorimotor control should be characterized more clearly, including the continuous dynamics of neural processes hut not limited to it. In particular, discrete conditions should be formalized mathematically as part of the biological process.

We have considered a simple word game called the word-morph. After making our participants play a stipulated number of word-morph games, we have analyzed the experimental data. We have given a detailed analysis of the learning involved in solving this word game. We propose that people are inclined to learn landmarks when they are asked to navigate from a source to a destination. We note that these landmarks are nodes that have high closeness-centrality ranking.

Departing from the (post-)Anthropocenic crisis state of today’s world, fuelled by the ongoing COVID-19 pandemic, various post-truth populist follies, and an apocalyptic WW3-scenario that has been hanging in the air since the 2022 invasion of Ukraine, this article argues for the possibility – and necessity – of an affirmative posthumanist-materialist mapping of hope. Embedded in the Deleuzoguattarian-Braidottian (see Deleuze and Guattari 2005 [1980]; Braidotti 2011 [1994]) methodology of critical cartography, and infused with critical posthumanist, new materialist, and queer theoretical perspectives, (...) this cartography of hope is sketched out against two permacrisis-infused positionalities: nostalgic humanism and tragic (post-)humanism. Forced to navigate between these two extremes, the critical cartography of hope presented here explores hope in numerous historico-philosophical (re-)configurations: from the premodern ‘hope-as-all-too-human’, to a more politicised early modern ‘hope-as-(politically-)human’ – representing hope’s first paradigm shift (politicisation), and from a four decades-long neoliberal redrawing of hope as ‘no-more-hope’ – hope’s second shift (depoliticisation) – to a critical (new) materialist plea to de-anthropocentrise and re-politicise hope – hope’s third and final post-Anthropocenic shift (re-politicisation). By mapping these (re-)configurations of hope, a philosophical plea is made for hope as a material(ist) praxis that can help us better understand – and counter – these extractive late capitalist, neoliberal more-than-human crisis times.

Within psychology, at least two research communities study spatial cognition. One community studies systematic errors in spatial memory and judgement, accounting for them as a consequence of and clue to normal perceptual and cognitive processing. The other community studies navigation in real space, isolating the contributions of various sensory cues and sensori- motor systems to successful navigation. The former group emphasizes error, the latter, selective mechanisms, environmental or evolutionary, that produce fine-tuned correct responses. How can these approaches be (...) reconciled and integrated? First, by showing why errors are impervious to selective pressures. The schematization that leads to errors is a natural consequence of normal perceptual and cognitive processes; it is inherent to the construction of mental spaces and to using them to make judgments in limited capacity working memory. Selection can act on particular instances of errors, yet it is not clear that selection can act on the general mechanisms that produce them. Next, in the wild, there are a variety of correctives. Finally, closer examination of navigation in the wild shows systematic errors, for example, over-shooting in dead reckoning across species. Here, too, environments may provide correctives, specifically, landmarks. General cognitive mechanisms generate general solutions. The errors inevitably produced may be reduced by local specific sensori-motor couplings as well as local environmental cues. Navigation, and other behaviors as well, are a consequence of both.

Concerns about the unsustainability of the conventional food system have promoted interest in alternative food networks, which are typically conceptualized through their differences from conventional food networks. Real-life AFNs, however, tend to show some similarities to the conventional food system. This hybridity has caused some criticism, but also, increasingly, calls for a more open examination of AFNs. Indeed, AFNs can be seen as relational to and shaped by the prevailing food system, for example the expectations the conventional system has promoted (...) among consumers. In this paper, through a multiple case study of nine alternative food retailers, we examine the negotiation of acceptable practice in AFNs and the challenges encountered in trying to do things alternatively. We employ convention theory, which encourages a view of action as socially negotiated and situational, and acknowledges plural legitimate notions of worth in guiding and justifying actions. Our findings show a plurality of ideals in the domain of AFNs and a complex navigation between the retailers’ own expressed ideals and considerations and perceived consumer expectations. The retailers’ justification of actions highlights several areas of tension in AFN practice, helping also to understand the challenges in adopting sustainable practices. While responding to consumer expectations sometimes involved adopting more conventional practices, the retailers also challenged consumers on certain issues. Our findings also show how even market-oriented AFNs may take radically alternative courses of action. The study supports the broader argument for examining all food networks in an open way, focusing on actual sustainability outcomes. (shrink)

The medial temporal lobe supports both navigation and declarative memory. On this basis, a theory of phylogenetic continuity has been proposed according to which episodic and semantic memories have evolved from egocentric and allocentric navigation in the physical world, respectively. Here, we explored the behavioral significance of this neurophysiological model by investigating the relationship between the performance of healthy individuals on a path integration and an episodic memory task. We investigated the path integration performance through a proprioceptive Triangle (...) Completion Task and assessed episodic memory through a picture recognition task. We evaluated the specificity of the association between performance in these two tasks by including in the study design a verbal semantic memory task. We also controlled for the effect of attention and working memory and tested the robustness of the results by including alternative versions of the path integration and semantic memory tasks. We found a significant positive correlation between the performance on the path integration the episodic, but not semantic, memory tasks. This pattern of correlation was not explained by general cognitive abilities and persisted also when considering a visual path integration task and a non-verbal semantic memory task. Importantly, a cross-validation analysis showed that participants' egocentric navigation abilities reliably predicted episodic memory performance. Altogether, our findings support the hypothesis of a phylogenetic continuity between egocentric navigation and episodic memory and pave the way for future research on the potential causal role of egocentric navigation on multiple forms of episodic memory.

We examine these challenges in the context of a feminist qualitative Big Data analysis of the hashtag event #WhyIStayed.

In doing so, this paper offers a feminist practice of holistic reflexivity in order to help social media researchers navigate and negotiate this terrain. (shrink)

We consider the target-reaching problem in plane scenes for a point robot which has a tactile sensor and can locate the target ray. It might have a compass, too, but it is not able to perceive the coordinates of its position nor to measure distances. The complexity of an algorithm is measured by the number of straight moves until reaching the target, as a function of the number of vertices of the scene. It is shown how the target point can (...) be reached by exhaustive search without using a compass, with the complexity exp). Using a compass, there is a target-reaching algorithm, based on rotation counting, with the complexity O. The decision problem, to recognize if the target cannot be reached because it belongs to an obstacle, cannot be solved by our type of robot. If the behaviour of a robot without compass is periodic in a homogeneous environment, it cannot solve the target-reaching problem. (shrink)

Scholars have noted persistent high rates of agricultural health and safety incidents and the need to develop more effective interventions. Participatory research provides an avenue to broaden the prevailing research paradigms and approaches by allowing those most impacted to illuminate and work to solve those aspects of their lives. One such approach is photovoice, an emancipatory visual narrative approach. Yet, despite its broad appeal, photovoice can be hard to implement. In this article, we leverage our experience using photovoice for a (...) farm children safety project to describe and reflect on the ethical and methodological aspects broadly relevant to agricultural health and safety topics. We first contextualize the tensions of navigating between photovoice, the research ethics committees (RECs) regulatory frameworks, and competing views on visual representations in agriculture. We then discuss the sources of risks to participants and researchers, how we addressed these risks, and how these risks unfolded during the research phase of the photovoice activity. We conclude with three lessons we (re)learned: the importance of collaborating with RECs, the need to increase preparation to limit psychological risks to participants and researchers, and avenues to augment the emancipatory power of photovoice in a virtual environment.

Dialogue has its origins in joint activities, which it serves to coordinate. Joint activities, in turn, usually emerge in hierarchically nested projects and subprojects. We propose that participants use dialogue to coordinate two kinds of transitions in these joint projects: vertical transitions, or entering and exiting joint projects; and horizontal transitions, or continuing within joint projects. The participants help signal these transitions with project markers, words such as uh-huh, m-hm, yeah, okay, or all right. These words have been studied mainly (...) as signals of listener feedback (back-channel signals) or turn-taking devices (acknowledgment tokens). We present evidence from several types of well-defined tasks that they are also part of a system of contrasts specialized for navigating joint projects. Uh-huh, m-hm and yeah are used for horizontal transitions, and okay and all right for vertical transitions. (shrink)

A visitor's experience of immersion in projection technology accumulates over time with the navigational movements that are called for through the digital artwork. The visitor travels through the artwork to gain an understanding of space and a sense of place within the visual field. An engaging display envelopes the visitor and thereby enhances their sense of immersion. An explorative movement within the virtual environment garners understanding, facilitates decision-making and intensifies navigation. Abstraction and symbolism in the visual experience offer a (...) metaphoric journey through the visual virtual experience. This article calls for a need to subvert and exploit rational imagery to stimulate the imagination in an effort to enhance immersion through the projection screen. The article will discuss how virtual environments fusing projection technologies with artistic imagery energizes experiential circumstances, promotes navigational movements and instigates perceptual shifts. In interactive media, the joystick navigates through a virtual environment as if painting the imagery of a place coincidently with its discovery. This self-referential journey shatters the sense of the fixed picture plane with a stable point of view established in traditional aesthetic engagement. The projection wall initially appears as a boundary for vision but acts, in essence, as a psychological screen for emergent experience. (shrink)

Evidence from egocentric space is cited to support bicoding of navigation in three-dimensional space. Horizontal distances and space are processed differently from the vertical. Indeed, effector systems are compatible in horizontal space, but potentially incompatible (or chaotic) during transitions to vertical motion. Navigation involves changes in coordinates, and animal models of navigation indicate that time has an important role.

We examine data on and models of small world properties and parameters of social networks. Our focus, on tie-strength, multilevel networks and searchability in strong-tie social networks, allows us to extend some of the questions and findings of recent research and the fit of small world models to sociological and anthropological data on human communities. We offer a 'navigability of strong ties' hypothesis about network topologies tested with data from kinship systems, but potentially applicable to corporate cultures and business networks.

ABSTRACT:In this address I argue that different perspectives on the normative foundations of corporate responsibility reflect underlying disagreements about the ideal arrangement of tasks between market and state. I initially recommend that scholars look back to the “division of moral labor” inspired by John Rawls’ seminal work on distributive justice in order to rethink why, and to what extent, corporations take on responsibilities normally within the purview of government. I then examine how this notion is related to recent theoretical work (...) in the field of business ethics. I thereafter turn to provide a brief outline of an alternative view that sees corporations as having responsibilities in so far as markets are sites of delegated oversight over the production of social goods that might otherwise be administered by the state.

How and when do we learn to understand other people’s perspectives and possibly divergent beliefs? This question has elicited much theoretical and empirical research. A puzzling finding has been that toddlers perform well on so-called implicit false belief (FB) tasks but do not show such capacities on traditional explicit FB tasks. I propose a navigational approach, which offers a hitherto ignored way of making sense of the seemingly contradictory results. The proposal involves a distinction between how we navigate FBs as (...) they relate to (1) our current affordances (here & now navigation) as opposed to (2) presently non-actual relations, where we need to leave our concrete embodied/situated viewpoint (counterfactual navigation). It is proposed that whereas toddlers seem able to understand FBs in their current affordance space, they do not yet possess the resources to navigate in abstraction from such concrete affordances, which explicit FB tests seem to require. It is hypothesized that counterfactual navigation depends on the development of “sensorimotor priors,” i.e., statistical expectations of own kinesthetic re-afference, which evidence now suggests matures around age four, consistent with core findings of explicit FB performance.

Synthetic biology has immense potential to ameliorate widespread environmental damage. The promise of such technology could, however, be argued to potentially risk the public, industry, or governments not curtailing their environmentally damaging behaviour or even worse exploit the possibility of this technology to do further damage. In such cases, there is the risk of a worse outcome than if the technology was not deployed. This risk is often couched as an objection to new technologies, that the technology produces a moral (...) hazard. This paper describes how to navigate a moral hazard argument and mitigate the possibility of a moral hazard. Navigating moral hazard arguments and mitigating the possibility of a moral hazard will improve the public and environmental impact of synthetic biology. (shrink)

The role of the ‘ideal’ in political philosophy is currently much discussed. These debates cast useful light on Mill's self-designation as ‘under the general designation of Socialist’. Considering Mill's assessment of potential property-relations on the grounds of their desirability, feasibility and ‘accessibility’ (disambiguated as ‘immediate-availability’, ‘eventual-availability’ and ‘conceivable-availability’) shows us not only how desirable and feasible he thought ‘utopian’ socialist schemes were, but which options we should implement. This, coupled with Mill's belief that a socialist ideal should guide social reforms (...) (as the North Star guides mariners), reveals much more clearly the extent of his socialist commitments (even if he thought political economists would be concerned with forms of individual property for some time to come). Moreover, this framework for assessments of ‘ideal’ institutions makes a useful contribution to an ongoing contemporary debate. (shrink)

This paper reports the findings from an interconnected set of experiments designed to assess children’s knowledge of the semantic interactions between negation and quantified NPs. Our main finding is that young children, unlike adults, systematically interpret these elements on the basis of their position in overt syntax.

We show that even when children’s semantic knowledge appears to differ from that (...) of adults, the observed differences.. (shrink)

Dutch context is reinforced by their peripheral position in the network and their ability to offshore work in a bid to contain costs, in addition to the influence of client domination. Therefore, territorial embeddedness is considered to be secondary to societal embeddedness which is intertwined with client interest while neglecting the interest of other network members. Nonetheless, the inter-firm relationship is complex, given the tension between societal, territorial and network embeddedness. While preferring Indian IT suppliers because of their low pricing, Dutch clients also insist on compliance with the institutional context of the Netherlands especially when it comes to Dutch employees. This results in hybridization which means that Indian IT suppliers find ways to adhere to the institutional framework for Dutch nationals while simultaneously insulating Indian employees from the same. Consequently, a highly unfair segmented internal labour market develops, with Dutch nationals being treated more favourably as compared to Indian nationals. Nonetheless, to address these violations, Indian employees prefer individual strategies of resilience and rework rather than a collectivization response. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Navigating Intersex Healthcare: My OdysseyCynthiaI was born in 1965 with what the medical community called “ambiguous genitalia.” My initial announcement as a boy was called into question upon closer assessment of my atypical anatomy by medical specialists at a children’s hospital in Chicago. That team of medical experts included a pediatric urologist and a pediatric endocrinologist, as well as a prominent pediatric surgeon, who was at that time presiding (...) president of the relatively newly established American Pediatric Surgeons Association. I have wondered over the years whether, or to what extent, that status and position had any important impact on the unfolding of my medical case.Just over 100 days after my birth, I was surgically and socially reassigned female, and renamed Cynthia. My mother and physician father, ages 25 and 30, respectively, with two young sons at home, did the best they could to move ahead in life as a young family. Part of our family story is that my unusual birth contributed to my parents’ decision to move away from Chicago, where both of my parents had been raised and wanted to settle, and where my father had many professional opportunities. We relocated to Southern California to make a “fresh start” where no one would know the dark secret too terrible to be shared with any beyond a small circle of close friends and family. It would never be talked about openly.With the exception of the rare and dreaded occasions of medical appointments with my primary care physician, or maybe an endocrinologist to renew hormone prescriptions, my parents chose [End Page E3] to have me travel from our home in San Diego to a clinician in Los Angeles, away from my father’s medical colleagues. This decision was puzzling to me at the time, and maybe more so now. These trips were a source of considerable stress and anxiety, as I had no idea of what to expect; my mother told me only that treatment would “help me get my period started.” I was instructed to tell my friends and teachers that I was taking off school on a weekday to go on a “shopping trip” with my mother. As far as I know, these trips were never discussed at home with my older brothers. I heard years later that my parents disclosed some information about me with my brothers when my parents travelled outside the country. They felt that my brothers should know what had happened to me in the event of a catastrophic accident that might prevent my parents from telling me themselves. I suppose they believed that I wasn’t ready at the time to be told my own life and medical history. I can’t say for sure.I don’t want to judge my parents too harshly for how they handled my medical care. I know that it was an extremely stressful and uncertain time for them, and peer support, which I know now is so vitally important for both parents and young affected individuals like myself, was not made available to us. I never thought to ask about such help, or even consider the idea that anyone else would be in a similar situation like mine. I don’t think I would have been even remotely comfortable or willing to discuss it openly at that point.In my early twenties, I had to face another milestone in my journey and in my interactions with the medical community. I had yet to have the vaginoplasty I was told I “needed.” There was no discussion as to whether or not I wanted it or not. It just had to be done, and I was aware of the limitations I had at this vulnerable time in my life when my peer group was sexually active and I was not. My awareness of the obstacle posed by my difference made me avoid the topic of dating; it was difficult even to think about the possibility of a romantic relationship. I put it out of my mind, but I knew that it was a significant concern for my parents. My physician father did most of the prodding to get me to acknowledge the reality... (shrink)

My contribution to this conversation sets out to accomplish two things: First, I offer a definition of epistemic pushback. Epistemic pushback is an expression of epistemic resistance that occurs regularly in classroom discussions that touch our core beliefs, sense of self, politics, or worldv iews. Epistemic pushback is structural: It broadly characterizes a family of cognitive, affective, and verbal tactics that are deployed regularly to dodge the challenging and exhausting chore of engaging topics and questions that scare us. It can (...) take such forms as direct deep hostility, knee jerk skepticism, or silence. Good teaching should not only track the production of knowledge, but also the production of ignorance. There are forms of epistemic pushback that are ignorance producing, so I work with students to cultivate a mindfulness around epistemic pushback by treating it as a ‘shadow text.’ The remainder of the paper explains the nature of shadow texts, and offers suggestions for how to navigate them.

Talk of anonymity floats freely and, in many contexts, rampantly in everyday, nonphilosophical discourse. But despite a surge of interest in anonymity—in anonymity protections, on the one hand, and anonymity harms and abuses, on the other—it is not at all clear what anonymity is. Is it simply a matter of being unknown? Or is anonymity something more, or less, than this? Unfortunately, existing analyses frame anonymity very generally as a phenomenon of unknowability and/or concealment. Consequently, they fail to capture what (...) distinguishes anonymity and anonymity relations from, for example, privacy and privacy relations. In this paper, I explore a more precise way of articulating anonymity, developing what I call the “central anonymity paradigm,” which frames anonymity as the result of a specific exercise of control in which true pieces of information about a person are concealed from others with an effect of dissociability. I use this paradigm to show how anonymity is characteristically interpersonal and network-relative, and deeply connected to issues of personal identity. (shrink)

In medical ethics, we are often concerned with questions that pertain predominantly to the treatment of a particular individual. However, in a number of cases it is crucial to broaden the scope of our moral inquiry beyond consideration of the individual alone, since the interests of the individual can come into conflict with the interests of the wider community. How should we resolve such conflicts between the interests of the individual and the collective? Most readers of this journal will likely (...) be familiar with the moral theory ‘classical utilitarianism’, which enjoins us to bring about the greatest happiness for the greatest number. This theory offers straightforward guidance in such conflicts, since it will typically be the case that the interests of the many will outweigh the interests of the individual in the utilitarian’s moral calculus. However, the simplicity of this approach is typically understood to be an inadequacy of the theory rather than an appropriate solution to these conflicts; contrary to the implications of classic utilitarianism, we would not believe it permissible to kill one innocent person in order to harvest life-saving organs for five others. Of course, adherents of utilitarianism have responded to this sort of problem by refining the theory in various ways. However, one may invoke different kinds of moral apparatus in order to navigate conflicts between the individual and the collective. In this issue, a number of papers engage with moral concepts that are central to different approaches to navigating these conflicts in practical debates. While it may clearly be in the interests of the collective to restrict the transmission of a dangerous infectious pathogen, methods of achieving this aim can be contrary to the interests of the particular individuals targeted by the intervention. Consider quarantine measures; in quarantine, individuals who are merely suspected of carrying …. (shrink)
