Visual masking of primes lowers prime visibility but spares processing of primes as reflected in prime–target congruence and prime–response compatibility effects. However, the question is how to appropriately measure prime visibility. Here, we tested the influence of three procedural variables on prime visibility measures: prime–target similarity, prime–response similarity, and the variability of prime–response mappings. Our results show that a low prime–target similarity is a favorable condition for a prime visibility measure because it increases the sensitivity (...) of this measure in comparison to a high prime–target similarity.

The ArgumentWhile there has been muchattention given to experiment in modern science studies, there has been astoundingly little concern spared over the practice ofquanitataivemeasurment.Thus myths about the unreasonable effectiveness of mathematice in science still abound. This paper presents: An explicit mathematical model of the stabilization of quantitative constants in a mathematical science to rival older Bayesian and classical accounts;a framework for writing a history of pracitces with regard to treatment of quantitative measurement erroe; resourece for the comparative sociology of differing (...) discipliness in this regard;and a prolegonmena to a critique of orthodox economics and accounting theories. The key to all these diverse themes is the realization that no one individual alone is capable of fixing the magnitude of a quantitative error estimate, and therefore the social construction of error must be given a more precise meaning, an therefore the social construction of error must be given a more precise menaing, and that this occurs through the istrumentality of meta-analysis.

The gender effects of COVID-19 are complex, and extend much beyond the issues of care work and domestic violence that have captured global attention. Some effects have been immediate, such as job losses, food shortages, and enhanced domestic work burdens; others will emerge in time, such as the depletion of savings and assets and pandemic-related widowhood, which would make recovery difficult. I use examples from India to outline the complexity of such outcomes, the limitations of the many telephone surveys conducted (...) during the pandemic, and the importance of anticipating both the immediate and the sequential effects. We can anticipate these effects by drawing on our knowledge of preexisting gender inequalities and people’s coping strategies under crises, as well as real-time media alerts. Prior conceptualization can help us design better surveys for capturing both the visible and less visible impact of the pandemic, as well as formulate more effective policies for mitigating the adverse effects. I also highlight the advantages of group-based approaches for protecting women’s livelihoods during such crises, and emphasize the need to create a synergy between feminist theory, evidence gathering, and policy formulation.

Conventional quantitative methods for the measurement of organizational legitimacy consider mainly three sources that make judgments about organizations visible: news media, accreditation bodies, and surveys. Over the last decade, however, social media have enabled ordinary citizens to bypass the gatekeeping function of these institutional evaluators and autonomously make individual judgments public. This inclusion of voices beyond functional and formally organized stakeholder groups potentially pluralizes the ongoing discussions about organizations. The individual judgments in blogs, tweets, and Facebook posts give indication about (...) the broader fit between an organization’s perceived behavior and heterogeneous social norms and therefore constitute an indicator of organizational legitimacy that can be accessed and measured. We propose the use of social media data and sentiment analysis to study the affect-based responses to organizational actions by citizens. We critically discuss and compare the method with existing quantitative methods for legitimacy measurement and apply them to a recent case in the banking industry. We discuss the value of the method for studying the process of legitimacy construction as the expression and negotiation of normative judgments about organizations by various evaluators. (shrink)

The electrification of East Africa followed an exceptionally uneven path. After about 50 years of relative neglect under colonial rule, the construction of hydroelectric dams moved electricity generation into the focus of late colonial development policy and became the major field of intervention for foreign donors after independence. The metrics of electricity attained a role as indicator and driver for economic growth, and therefore as a target figure in economic policy, one that was arguably not justified by their actual significance (...) in the energy landscape of East Africa. This paper analyses both the global preconditions of this shift and its local repercussions. Rather than the physical visibility of electricity in the form of large dams and high-tension lines, the paper focuses on the processes that rendered electricity ontologically visible. It traces attempts by engineers, expert advisors, or development consultants to translate the complex information associated with the generation and consumption of electricity into calculable and comparable metrics. The paper scrutinises these commensuration processes in terms of the resources and knowledge they required, the frameworks of agency they opened, and the way they fed into wider discourses of development. It asks how the metrics of electricity themselves became part of the colonial and postcolonial politics of calculation, as they increasingly came to be seen as a medium for conceiving national economies. This trend was reinforced by the ascent of development economics in the 1950s and its influence on the ontological foundations of international development cooperation and post-independence nation-building. Because of the calculability and capital-intensity of its production, electricity lent itself perfectly to an economic policy based on macroeconomic aggregates and abstract growth models. Conversely, the electricity bias of international development agencies and the national government rendered rural, non-commercial, and non-productive energy use largely invisible. (shrink)

Homonyms, i.e. ambiguous words like ‘score’, have different meanings in different contexts. Previous research indicates that all potential meanings of a homonym are first accessed in parallel before one of the meanings is selected in a competitive race. If these processes are automatic, these processes of selection should even be observed when homonyms are shown subliminally. This study measured the time course of subliminal and supraliminal priming by homonyms with a frequent and a rare meaning in a neutral context, using (...) a lexical decision task. In the subliminal condition, priming across prime-target asynchronies ranging from 100 ms to 1.5 s indicated that the dominant meaning of homonyms was facilitated and the subordinate meaning was inhibited. This indicates that selection of meaning was much faster with subliminal presentation than with supraliminal presentation. Awareness of a prime might decelerate an otherwise rapid selection process.

Comparisons of indirect measures with direct measures can help elucidate the relationship between nonconscious and conscious perception. We report three experiments on masked word priming in which we observed a negative correlation between prime discriminability and priming , i.e. where priming decreased with increasing prime visibility. While such observations are rare , they may indicate a conflict between conscious and nonconscious processing when primes are shown close to the subjective visibility threshold for the priming-relevant information. For (...) instance, such a conflict could occur between nonconscious processing of a prime’s meaning and conscious perception of prime letters. Theoretical accounts that discuss similar conflicts assume that the conflict is resolved either by automatically prioritising conscious processes or by discounting the estimated confusion caused by a prime-target pair . In both cases, priming is predicted to decrease when prime visibility increases from below threshold to perithreshold levels. Therefore, we suggest that negative priming-d’ relationships are most likely observed when the d’ measure assesses prime visibility at a level of representation that is below the level of representation at which priming arises, in terms of a putative hierarchy of word processing.

Quantitative and qualitative research writing is thought to differ in a number of ways, which include the visibility given to the human agents involved, that is, writers and participants in the study. However, most studies have so far centred on writer visibility alone, which has been measured principally through personal pronoun use. This paper approaches the issue of writer and participant visibility in one area of research where both quantitative and qualitative methods are frequent, namely health sciences. (...) A new methodology is applied, based on the presence of verbs that imply a human agent and thus potentially offer an opportunity for writer or participant visibility. Two corpora are built to represent quantitative and qualitative research writing in health sciences, and quantitative data are obtained. Exploration of the most frequent human-agent verbs, their active uses and their subjects shows that both quantitative and qualitative researchers in health science maintain low writer visibility, but that both writers and participants are more visible in the case of studies using qualitative methodology. These findings are discussed in the light of the bibliography, and pointers are provided for future research. The contribution of the present paper to corpus-assisted research on academic writing is highlighted. Finally, some applications for teaching scientific writing at graduate level are proposed.

Subliminal perception occurs when prime stimuli that participants claim not to be aware of nevertheless influence subsequent processing of a target. This claim, however, critically depends on correct methods to assess prime awareness. Typically, d9 (‘‘d prime’’) tasks administered after a priming task are used to establish that people are unable to discriminate between different primes. Here, we show that such d9 tasks are influenced by the nature of the target, by attentional factors, and by the delay between stimulus presentation (...) and response. Our results suggest that the standard d9 task is not a straightforward measure of prime visibility. We discuss the implications of our findings for subliminal perception research. (shrink)

We present several quantitative analyses of the prevalence and visibility of women in moral, political, and social philosophy, compared to other areas of philosophy, and how the situation has changed over time. Measures include faculty lists from the Philosophical Gourmet Report, PhD job placement data from the Academic Placement Data and Analysis project, the National Science Foundation's Survey of Earned Doctorates, conference programs of the American Philosophical Association, authorship in elite philosophy journals, citation in the Stanford Encyclopedia of (...) Philosophy, and extended discussion in abstracts from the Philosopher's Index. Our data strongly support three conclusions: (1) Gender disparity remains large in mainstream Anglophone philosophy; (2) ethics, construed broadly to include social and political philosophy, is closer to gender parity than are other fields in philosophy; and (3) women's involvement in philosophy has increased since the 1970s. However, by most measures, women's involvement and visibility in mainstream Anglophone philosophy has increased only slowly; and by some measures there has been virtually no gain since the 1990s. We find mixed evidence on the question of whether gender disparity is even more pronounced at the highest level of visibility or prestige than at more moderate levels of visibility or prestige. -/- .

The ArgumentThe vine lousePhylloxera vastatrixbecame a “pest” as it was transferred from North America and from France to Germany during the 1870s. Embodying the “invading alien,” it assumed a cultural position that increasingly gained importance in Imperial Germany. In this process, the minute insect, living invisibly underground, was made visible and became constitutive of the scientific-technological object, “pest,” pertaining to a scientific discipline, modern economic entomology. The “pest” phylloxera emerged by being made visible in a way that enabled control (...) class='Hi'>measures against it. Thus, visibility functioned as a prerequisite for control measures. I differentiate between social visibility and physical visibility, as well as between social control and physical control of the “introduced pest.” The object phylloxera emerged at the intersection of techniques of social control such as surveillance, techniques of physical control such as disinfection, and representational practices of the sciences such as mathematics and graphics. The space of its visibility was not the vineyard as property of a vintner but the vineyard as national territory, where German (viti-) culture was defended against foreign infiltration and destruction. Many vintners had alternate visions of the grapevine disease, they resented the invasion and destruction of their vineyards by government officers, and thus they did not participate in the social and epistemic constitution of the “pest.” By 1914, the “introduced pest” had not yet become an effective “machinery.” However, the “pest” as an object of scientific knowledge emerged together with economic entomology. The field became organized as a discipline in Germany in 1913, forty years after the phylloxera had first aroused the minds of some worried Wilhelmians, and, together with its nationalistic images, the field of “pest” control became organized towards a redefinition of German society and its perceived dangers.

Although women have made important inroads in science and engineering since the early 1970s, their progress in these fields has stalled over the past several years. This study looks at women in science and engineering careers in the 1970s and 1980s, documenting differences in career outcomes between men and women and between women of different races and ethnic backgrounds. The panel presents what is known about the following questions and explores their policy implications: In what sectors are female Ph.D.s employed? (...) What salary disparities exist between men and women in these fields? How is marital status associated with career attainment? Does it help a career to have a postdoctoral appointment? How well are female scientists and engineers represented in management? Within the broader context of education and the labor market, the book provides detailed comparisons between men and women Ph.D.s in a number of measures: financial support for education, academic rank achieved, salary, and others. The study covers engineering; the mathematical, physical, life, and social and behavioral sciences; medical school faculty; and recipients of National Institutes of Health grants. Findings and recommendations in this volume will be of interest to practitioners, faculty, and students in science and engineering as well as education administrators, employers, and researchers in these fields.

In the late nineteenth century, British anthropometrists attempted to normalize the practice of measuring bodies as they sought to collate data about the health and racial makeup of their fellow citizens. As the country’s leading anthropometrists, Francis Galton and Charles Roberts worked to overcome suspicion about their motives and tried to establish the value of recording physical dimensions from their subjects’ perspective. For Galton, the father of the eugenics movement, the attainment of objective self-knowledge figured alongside the ranking of one’s (...) physique and faculties against established norms. The competitive tests at Galton’s anthropometric laboratory were meant to help subjects identify their strengths and weaknesses, ultimately revealing their level of eugenic fitness. Roberts, on the other hand, saw the particular value of anthropometric data in informing economic and social policy, but capitalized on parents’ interest in their children’s growth rates to encourage regular monitoring of their physical development. While both Galton and Roberts hoped that individuals would ultimately furnish experts with their anthropometric data to analyze, they both understood that the public would need to have explained the practical purposes of such studies and to familiarize themselves with their methods. This article argues that while anthropometry did not become a fully domestic practice in this period, it became a more visible one, paving the way for individuals to take an interest in metrical evaluations of their bodies in the coming years.

Background Relatively little information is available regarding the level of acceptance of evolution and knowledge about evolution in different educational settings in Europe. The aim of the present study is to fill this gap and provide a comprehensive overview of the current state of research regarding evolutionary knowledge and acceptance of students and teachers across Europe, based on a systematic literature review. -/- Results We identified 56 papers for the period 2010–2020, presenting results for 29 European countries. Both knowledge and (...) acceptance of evolution were assessed in 17 studies. Out of 13 instruments most commonly used in the literature, five have been used in the European context so far: ACORNS, CINS, I-SEA, KEE and MATE. Thirty-one other instruments were identified of which 16 were used in studies on knowledge and 15 in studies on acceptance. The extent of knowledge was hard to compare even within groups of the same education level due to the application of different instruments and assessment of different key concepts. Our results illustrate the persistence of misconceptions through all education levels. Comparing acceptance among different education levels and countries revealed a high diversity. However, a lack of evolution in curricula tended to be associated with rejection of evolution in some countries. European studies that investigated both acceptance of evolution and knowledge about evolution varied highly concerning the existence and strength of the relationship between these factors. However, some trends are visible, such as an increase of strength of the relationship the higher the education level. -/- Conclusions The present review highlights the lack of a standardized assessment of evolutionary knowledge and acceptance of evolution across Europe and, therefore, of reasonably comparable data. Moreover, the review revealed that only about one-third of all studies on acceptance and/or knowledge about evolution provided evidence for local validity and reliability. We suggest the use of assessment categories for both knowledge and acceptance instruments to allow for interpretation and comparison of sum scores among different sample groups. This, along with prospective comparative research based on similar samples, paves the way for future research aimed at overcoming current biases and inconsistencies in results. (shrink)

This study, presenting a history of the measurement of light intensity from its first hesitant emergence to its gradual definition as a scientific subject, explores two major themes. The first concerns the adoption by the evolving physics and engineering communities of quantitative measures of light intensity around the turn of the twentieth century. The mathematisation of light measurement was a contentious process that hinged on finding an acceptable relationship between the mutable response of the human eye and the more (...) easily stabilised, but less encompassing, techniques of physical measurement. -/- A second theme is the exploration of light measurement as an example of ‘peripheral science’. Among the characteristics of such a science, I identify the lack of a coherent research tradition and the persistent partitioning of the subject between disparate groups of practitioners. Light measurement straddled the conventional categories of ‘science’ and ‘technology’, and was influenced by such distinct factors as utilitarian requirements, technological innovation, human perception and bureaucratisation. Peripheral fields such as this, which may be typical of much of modern science and technology, have hitherto received little attention from historians. -/- These themes are pursued with reference to the social and technological factors which were combined inextricably in the development of the subject. The intensity of light gained only sporadic attention until the late nineteenth century. Measured for the utilitarian needs of the gas lighting industry from the second half of the century, light intensity was appropriated by members of the nascent electric lighting industry, too, in their search for a standard of illumination. By the turn of the century the ‘illuminating engineering movement’ was becoming an organised, if eclectic, community which promoted research into and standards for the measurement of light intensity. -/- The twentieth-century development of the subject was moulded by organisation and institutionalisation. Between 1900 and 1920, the new national and industrial laboratories in Britain, America and Germany were crucial in stabilising the subject. In the inter-war period, committees and international commissions sought to standardise light measurement and to promote research. Such government- and industry-supported delegations, rather than academic institutions, were primarily responsible for the ‘construction’ of the subject. Practitioners increasingly came to interpret the three topics of photometry (visible light measurement), colorimetry (the measurement of colour) and radiometry (the measurement of invisible radiations) as aspects of a broader study, and enthusiastically applied them to industrial and scientific problems. -/- From the 1920s, the long-established visual methods of observation were increasingly replaced by physical means of light measurement, a process initially contingent on scientific fashion more than demonstrated superiority. New photoelectric techniques for measuring light intensity engendered new commercial instruments, a trend which accelerated in the following decade when photometric measurement was applied with limited success to a range of industrial problems. Seeds sowed in the 1920s – namely commercialisation and industrial application, the transition from visual to ‘physical’ methods, and the search for fundamental limitations in light measurement – gave the subject substantially the form it was to retain over the next half-century.

Drawing on work done by Helmholtz, I argue that Reid was in no position to infer that objects appear as if projected on the inner surface of a sphere, or that they have the geometric properties of such projections even though they do not look concave towards the eye. A careful consideration of the phenomena of visual experience, as further illuminated by the practice of visual artists, should have led him to conclude that the sides of visible appearances either look (...) straight, in which case their angles appear to approximate Euclidean measures, or their angles do not appear to approximate Euclidean measures for straight line figures, in which case their sides do not look straight.

Drawing on a qualitative, multi-case study of three kinds of geographically tethered gig work—ride-hailing, delivery, and domestic services platforms—in the United States, I examine how workers anticipate the influences of metrics, live with metrics, and cope with algorithmic precarity. Data for this project include in-depth interviews with 50 gig workers about their efforts to interpret and manage metrics as part of their everyday work practices. The analysis reveals that participants were anxious about metrics primarily because of the disciplinary outcomes, that (...) are, the threat of job loss and the valued job features. It also directs attention to how workers felt and experienced customer-sourced ratings and system-generated behavioral metrics variously across platforms. Information asymmetries and the perceived lack of control also intensified a sense of powerlessness among participants. While participants articulated strategies that aimed at managing the uncertainty of customer-sourced ratings—and more precisely, the work-related uncertainty created by “difficult customers”—throughout service interactions, their feelings of anxiety could not be resolved. Furthermore, the (in)visibility of metrics, the settings of platform-mediated worker–customer interactions, and workers’ platform dependence contributed to the varying disciplinary power of metrics. The study contributes to understanding how metrics as affective measures mediate the trilateral relationship between platforms, workers, and customers in the gig economy. (shrink)

Theories of culture and action, especially after the cognitive turn, have developed more complex understandings of how unconscious, embodied, internalized culture motivates action. As our theories have become more sophisticated, our methods for capturing these internal processes have not kept up and we struggle to adjudicate among theories of how culture shapes action. This article discusses what I call “productive” methods: methods that observe people creating a cultural object. Productive methods, I argue, are well suited for drawing out moments of (...) shared automatic cognition and resonance. To demonstrate the value of productive methods, I describe my method of asking focus group participants to devise and draw AIDS campaign posters collectively. I then 1) show how this productive method made visible distinct moments of both automatic and deliberative cognition, 2) offer an operational definition of resonance and demonstrate how the process of drawing revealed moments of resonance, and 3) suggest how this method allowed me to investigate the relationship between cognition and resonance and their effect on action. To conclude, I discuss strategies for using productive methods and advocate for their use in measuring culture. (shrink)

Although the majority of young children now spend time in nonparental child care, we know relatively little about who provides this care and how its costs are distributed among parents, government, and other family members. In this article we use data from a survey of New York City families with children younger than six to estimate the contribution of parental expenditures, government assistance, and the market value of “donated” caregiving time by family, friends, and relatives. We conclude that uncompensated caregivers (...) provide a substantial share of child care that is “invisible” in conventional economic measures. (shrink)

Philosophical pragmatism takes human experience as the touchstone of any theorizing. Authors like William James and F.C.S. Schiller suggested to transform philosophy into a critical and emancipatory project, turning the quest for truth into a project of creative and responsible world-making. Their basic insight that man is the measure of all things demands for being actively engaged in building a better world. As pragmatism denies objective criteria for critique, listening to a plurality of voices and their experiences becomes crucial. This (...) chapter offers a humanist re-reading of philosophical pragmatism and explores its challenges and prospects. With pointing out problematic assumptions in the work of James and Schiller, the unfinished agenda of their pragmatic humanism becomes visible. (shrink)

Institutional investors are increasingly focusing on firms that prioritise Corporate Social Responsibility. In the absence of any objective measure of a firm's CSR Performance, their investment choices are largely guided by independent rating indices that rank firms according to their social performance metrics. As a result, firms looking to increase their attractiveness as targets of social investment focus their CSR efforts on increasing the visibility of activities that are recognised by such indices. However, the validity of these indices as (...) accurate measures of firms' actual social performance has repeatedly been called into question. This means that the ability of these indices to measure and report on firms' actual social impact cannot be ascertained with any degree of accuracy. The result is that firms are incentivised to engage in activities that cannot be said to improve social responsibility, and may even ultimately harm society. Thus, another method of measuring CSP must be found that enables firms to measure their true impact on society. We propose a new approach to measuring CSP that is integrated with stakeholder theory. Such an approach provides managers of firms with an interest in engaging in real social development for the purposes of ensuring firm survival with the ability to understand their social obligations, and the ability to measure the resulting benefit to society.

This article presents a meta-analysis of the impact of minimal exposure to affective stimuli on the emergence of enduring conscious affective feelings. Theories often assume that such affective feelings are linked to automatic appraisals of events (i.e. in the absence of an evaluative processing goal). However, few studies have tested this hypothesis. Moreover, they have provided divergent results. We propose a meta-analysis of these studies to get a clearer picture on this issue. The meta-analysis includes 22 studies (37 effect sizes; (...) combined N = 2159) in which participants were repeatedly exposed to affective stimuli in the absence of an evaluative processing goal before their mood was measured. In this analysis, we focused on the type of stimulus presentation (i.e. visible vs. masked) as well as on the type of stimulus (i.e. faces, pictures, words). The results indicate that the effect of a stimulus is moderated by the visibility of the stimuli. Repeated exposure to visible stimuli leads to congruency effects (i.e. positive stimuli lead to positive feelings), whereas exposure to masked stimuli leads to contrast effects (i.e. positive stimuli lead to negative feelings). Moreover, these effects seem to be restricted to some types of stimuli, with no detectable effects of emotional faces. (shrink)

The paper discusses the philosophical conclusions, which the interrelation between quantum mechanics and general relativity implies by quantum measure. Quantum measure is three-dimensional, both universal as the Borel measure and complete as the Lebesgue one. Its unit is a quantum bit (qubit) and can be considered as a generalization of the unit of classical information, a bit. It allows quantum mechanics to be interpreted in terms of quantum information, and all physical processes to be seen as informational in a generalized (...) sense. This implies a fundamental connection between the physical and material, on the one hand, and the mathematical and ideal, on the other hand. Quantum measure unifies them by a common and joint informational unit. Furthermore the approach clears up philosophically how quantum mechanics and general relativity can be understood correspondingly as the holistic and temporal aspect of one and the same, the state of a quantum system, e.g. that of the universe as a whole. The key link between them is the notion of the Bekenstein bound as well as that of quantum temperature. General relativity can be interpreted as a special particular case of quantum gravity. All principles underlain by Einstein (1918) reduce the latter to the former. Consequently their generalization and therefore violation addresses directly a theory of quantum gravity. Quantum measure reinterprets newly the “Bing Bang” theories about the beginning of the universe. It measures jointly any quantum leap and smooth motion complementary to each other and thus, the jump-like initiation of anything and the corresponding continuous process of its appearance. Quantum measure unifies the “Big Bang” and the whole visible expansion of the universe as two complementary “halves” of one and the same, the set of all states of the universe as a whole. It is a scientific viewpoint to the “creation from nothing”. (shrink)

Recent work by Wan and McLean has shown that all quantum measurements may be reduced to local position measurements. Using an array of particle detectors as the measuring apparatus we show how a model employing superselection rules and unitary evolution leads to a single detector triggering in each act of measurement. We also present an explicit model of particle detection as a unitary ionization process producing a single ion in the detector, subsequent amplification of which to the visible can be (...) described adequately in classical terms.

Wagering contingent on a previous decision, or post-decision wagering, has recently been proposed to measure conscious awareness. Whilst intuitively appealing, it remains unclear whether economic context interacts with subjective confidence and how such interactions might impact on the measurement of awareness. Here we propose a signal detection model which predicts that advantageous wagers placed on the identity of preceding stimuli are affected by loss aversion, despite stimulus visibility remaining constant. This pattern of predicted results was evident in a psychophysical (...) task where we independently manipulated perceptual and economic factors. Changes in wagering behaviour induced by changes in wager size were largely driven by changes in criterion, consistent with the model. However, for near-threshold stimuli, a reduction in wagering efficiency was also evident, consistent with an apparent but potentially illusory decrease in awareness of the stimulus. These findings challenge an assertion that post-decision wagering provides a direct index of subjective awareness. (shrink)

Our aim in this article is to define the difficulties that clinical ethics services encounter when they are asked to demonstrate the value a clinical ethics service (CES) could and should have for an institution and those it serves. The topic emerged out of numerous related presentations at the Un- Conference hosted by the Cleveland Clinic in August 2018 that identified challenges of articulating the value of clinical ethics work for hospital administrators. After a review these talks, it was apparent (...) that the field of clinical ethics may be at a crisis of sorts due to increased pressure to provide explicit measures to healthcare institutions to concretely demonstrate that CESs make a valuable difference in healthcare delivery. In this article, we grapple with how to satisfy the need for demonstrable value in a field in which metrics alone may not capture the scope of clinical ethics practice. We suggest that capturing the value of a CES has been difficult because the benefits of ethics consultation may be overt or attributable to the CES, but are often hidden due to the systems-level and process-oriented nature of clinical ethics work. Part of the difficulty in demonstrating the value of CESs is capturing and conveying all of the ways the integration of a CES throughout an institution positively affects patients, families, visitors, healthcare professionals, administrators, and the institution itself. Our aim is to (1) elucidate the multifaceted value added by a CES, including value that tends to be hidden and (2) suggest how to demonstrate value to others in a way that is not simplistic or reductionistic.

Air pollution is one of the largest environmental health risks globally but is often imperceptible to people. Air quality smartphone applications provide real-time localized air quality information and have the potential to help people learn about the health effects of air pollution and enable them to take action to protect their health. Hundreds of air quality apps are now available; however, there is scant information on how effective these mobile apps are at educating stakeholders about air pollution and promoting behavioral (...) change to protect their health. In this paper, we test how intrinsic and extrinsic motivations can enhance users’ engagement with air quality information through an app, and favor changes in protective behavior. We developed an air quality app, AirForU, with a built-in research study that was downloaded by 2740 users. We found that engagement was higher for users with intrinsic motivations, such as those who are health conscious, either because they are suffering from heart disease or other conditions aggravated by air pollution, or because they exercise frequently and want to maintain a healthy lifestyle. Extrinsic motivations such as notifications were also effective. App users stated that they frequently shared air quality information with others, learned about the Air Quality Index, and took measures to protect their health while using AirForU app. (shrink)

Background Speech understanding may rely not only on auditory, but also on visual information. Non-invasive functional neuroimaging techniques can expose the neural processes underlying the integration of multisensory processes required for speech understanding in humans. Nevertheless, noise (from fMRI) limits the usefulness in auditory experiments, and electromagnetic artefacts caused by electronic implants worn by subjects can severely distort the scans (EEG, fMRI). Therefore, we assessed audio-visual activation of temporal cortex with a silent, optical neuroimaging technique: functional near-infrared spectroscopy (fNIRS). Methods (...) We studied temporal cortical activation as represented by concentration changes of oxy- and deoxy-hemoglobin in four, easy-to-apply fNIRS optical channels of 33 normal-hearing adult subjects and 5 post-lingually deaf cochlear implant (CI) users in response to supra-threshold unisensory auditory and visual, as well as to congruent auditory-visual speech stimuli. Results Activation effects were not visible from single fNIRS channels. However, by discounting physiological noise through reference channel subtraction, auditory, visual and audiovisual speech stimuli evoked concentration changes for all sensory modalities in both cohorts (p<0.001). Auditory stimulation evoked larger concentration changes than visual stimuli (p<0.001). A saturation effect was observed for the audiovisual condition. Conclusions Physiological, systemic noise can be removed from fNIRS signals by reference channel subtraction. The observed multisensory enhancement of an auditory cortical channel can be plausibly described by a simple addition of the auditory and visual signals with saturation. (shrink)

Daily function depends on an ability to mentally map our environment. Environmental factors such as visibility and layout, and internal factors such as psychological stress, can challenge spatial memory and efficient navigation. Importantly, people vary dramatically in their ability to navigate flexibly and overcome such challenges. In this paper, we present an overview of “schema theory” and our view of its relevance to navigational memory research. We review several studies from our group and others, that integrate manipulations of environmental (...) complexity and affective state in order to gain a richer understanding of the mechanisms that underlie individual differences in navigational memory. Our most recent data explicitly link such individual differences to ideas rooted in schema theory, and we discuss the potential for this work to advance our understanding of cognitive decline with aging. The data from this body of work highlight the powerful impacts of individual cognitive traits and affective states on the way people take advantage of environmental features and adopt navigational strategies.

The assessment of chronic pain is a highly unmet medical need. Chronic pain is also the subject of a large and costly category of legal claims. Yet, with pain cases, the jury always face a doubt: is the claimant faking or malingering? How can we be assured that the claimant is 'really' in pain? Most recently, several new neuroimaging technologies are promising to solve these questions, by rendering pain visible, measurable and, to some degree, verifiable. The results of these advancements (...) have prompted us to think of pain in a different way, i.e. as an altered brain state in which functional connections are modified, with components of degenerative aspects. But, does this imply the stronger claim that these technologies allow us to 'know', or to literally 'see', the pain of others? Is the pain being objectified by these techniques? And if so, what might the law do differently, or do better? (shrink)

The measurement of light and colour has always been a peripheral science. Light became a 'disciplined' quantity over the period of a century, but the specialist communities that measured it did not.

The visibility of environmental problems and the increasing awareness of associated consequences have made environmental issues salient in Zambia. The purpose of this study was to investigate correlations between the social and psychological influences affecting college students in Zambia, and the behaviours perceived by them to be appropriately environmentally friendly. The underlying social and psychological factors that would determine individuals’ attitudinal responses toward appropriate environmental behaviour were assessed. The study attempted to measure behavioural tendencies towards environmental conservation. Behaviour involving (...) energy and water conservation (EW) was consistently rated as the most important, and appropriate category of environmental behaviour, whereas social and political action (SP) was viewed as the least favourable behaviour according to the respondents in Zambia. The respondents who were older in the graduate level of the study and had frequently contact with environmental education activities and courses were more likely to hold positive behavioural tendencies toward environmental conservation in general.

This seems to contradict the description of decay in Quantum Mechanics: according to Gamow a spherical wave is produced and moves radially according to Schrödinger’s equation. It is as if the interaction with the supersaturated vapor turned the wave into a particle. The aim of this note is to place this effect in the context (...) of Schrödinger’s Quantum Mechanics. We shall see that the properties of the initial wave function suggest the introduction of a semiclassical formalism in which the \ -wave can be described as a collection of semiclassical wavelets; each of them interacts with an atom and forms an entangled state. The interaction can be regarded as a semiclassical inelastic scattering event. The measurement selects the wave function of one of the ions, with a probability given by Born’s rule. This ion interacts with the atoms nearby leading to the formation of a droplet. One can reasonably assume that also the wavelet entangled with the selected ion has probability one to remain as part of the description of the system. The measurement process is therefore represented by a unitary operator. The wavelet remains sharply localized on a classical path \ It is still a probability wave: it determines the probability that another atom be ionized. This probability is essentially zero unless the atom lies on \ . This gives the visible track. (shrink)

The article examines epistemological and ontological underpinnings of reasearch performed by means of magnetic resonance imaging and functional magnetic resonance imaging. It takes as its guiding line the important distinction between instruments and apparatuses drawn by Rom Harré. According to Harré, instruments such as barometers or thermometers do not cause the states they measure into existence. Apparatuses, in contradistinction, cause material states into existence to begin with, whereby theses states are subsequently processed according to suitable methods. Thus, when the objects (...) of examination are subjected to 2 or more Tesla in fMRI, a strength of magnetic field never occuring in earthly nature, technical means literally create the states to be examined. Close examination of the functioning of MRI and fMRI indicates that brain states, e.g., are not simply read, or perceived as degrees of temperature are read on scale. Hence, one does not see any mental funtion when looking at fMRI outputs, for the visible output has been semantically processed on the basis of invisible quantum mechanical processes that have undergone translations into digital data caused by the fMRI device itself.

The occurrence of oscillatory behaviours in living cells can be viewed as a visible consequence of stable, regulatory homeostatic cycles. Therefore, they may be used as experimental windows on the underlying physiological mechanisms. Recent studies show that growing pollen tubes are an excellent biological model for these purposes. They unite experimental simplicity with clear oscillatory patterns of both structural and temporal features, most being measurable during real‐time in live cells. There is evidence that these cellular oscillators involve an integrated input (...) of plasma membrane ion fluxes, and a cytosolic choreography of protons, calcium and, most likely, potassium and chloride. In turn, these can create positive feedback regulation loops that are able to generate and self‐sustain a number of spatial and temporal patterns. Other features, including cell wall assembly and rheology, turgor, and the cytoskeleton, play important roles and are targets or modulators of ion dynamics. Many of these features have similarities with other cell types, notably with apical‐growing cells. Pollen tubes may thus serve as a powerful model for exploring the basis of cell growth and morphogenesis. BioEssays 23:86–94, 2001. © 2001 John Wiley & Sons, Inc. (shrink)

Light increment thresholds were measured on either side of one of the illusory contours of a white-on-black Kanizsa square and on the illusory contour itself. The data show that thresholds are elevated when measured on either side of the illusory border. These elevations diminish with increasing distance of the target spot from the white elements which induce the illusory figure. The most striking result, however, is that threshold elevations are considerably lower or even absent when the target is located on (...) the illusory contour itself. At an equivalent position in a control figure where no illusory contour is visible, such a threshold decrease does not occur. The present observations add empirical support to neural theories of illusory form perception. (shrink)

In recent years, inverse spectra were investigated with imaging optics and a quantitative description with radiometric units was suggested. It could be shown that inverse spectra complement each other additively to a constant intensity level. Since optical intensity in radiometric units is a power area density, it can be expected that energy densities of inverse spectra also fulfill an inversion equation and complement each other. In this contribution we report findings on a measurement of the power area density of inverse (...) spectra for the near ultraviolet, visible and the infrared spectral range. They show the existence of corresponding spectral regions ultra-yellow and infra-cyan in the inverted spectrum and thereby present additional experimental evidence for equivalence of inverse spectra beyond the visible range.

Prevailing in the survey industry is the conception that public sentiment is a simple arithmetic function of individuals’ sentiments, many of them held only privately, maybe even secretly. Against this conception, the present paper argues that public sentiment is better construed as strategic deductions from publicly available evidence—a matter of the public working out a common sentiment from publicly available information. This conception diverges dramatically from a conception of public sentiment as the weight of private thoughts or beliefs—items that may (...) be measured by a poll, at least when the appropriate survey methodologies are correctly administered and analyzed. The reason to prefer a conception emphasizing public materials is perhaps obvious: only that which enjoys public visibility has a chance of effecting change. If measuring public sentiment is truly in service of taking stock of forces at work on the social-political stage, that is quite sufficient—as the arguments presented here will show—to prefer the approach on offer here over those currently prevailing.

Man is endowed with brain and mind for comprehending reality of the world. Brain is material entity and is observable, while mind is a non-physical conceived entity. Scientific investigations enhance our knowledge of the functioning of brain and its constituents. They indicate mind-brain association but do not rule out the possibility, in which mind is a property of brain. The perceived reality of the world has both objective and subjective components. The objective components are attributed to brain either alone or (...) in association with mind. The subjective components are considered to be the creations of mind but they appear to contain grains of reality. Attempts made to separate these grains have succeeded partially. One hopes for complete success only after the incorporation of a few missing ingredients. It is our contention that the missing ingredients are human being as an entangled quantum entity - photon field, quantum entity's capability to read information from photon fields of other humans and from its own field reflected by the environment. The evidence for the first ingredient is provided by the analysis of spontaneously emitted visible range photon signals by human beings. The other two ingredients put usual charge- photon interaction in proper context. The experimental results relevant to mind- brain interface are briefly described. A few minutes' time series of small portion of these signals determines their nine properties, which establish quantum nature of signal, and specify quantum state of the dominant component to be squeezed state. Six properties differ in signals emitted at 12 anatomical sites of the same person. Profile of a property for a person is the set of its values at 12 sites. Profile is very informative and can discriminate persons with differing holistic features. Cluster analysis offers procedures for measuring qualitative holistic features e.g. procedure for measuring ‘meditativeness' of a person. The incorporation of other two ingredients chalks out a route for answering the question who we are? (shrink)

Explainable artificial intelligence (XAI) is an emerging, multidisciplinary field of research that seeks to develop methods and tools for making AI systems more explainable or interpretable. XAI researchers increasingly recognise explainability as a context-, audience- and purpose-sensitive phenomenon, rather than a single well-defined property that can be directly measured and optimised. However, since there is currently no overarching definition of explainability, this poses a risk of miscommunication between the many different researchers within this multidisciplinary space. This is the problem we (...) seek to address in this paper. We outline a framework, called Explanatory Pragmatism, which we argue has two attractive features. First, it allows us to conceptualise explainability in explicitly context-, audience- and purpose-relative terms, while retaining a unified underlying definition of explainability. Second, it makes visible any normative disagreements that may underpin conflicting claims about explainability regarding the purposes for which explanations are sought. Third, it allows us to distinguish several dimensions of AI explainability. We illustrate this framework by applying it to a case study involving a machine learning model for predicting whether patients suffering disorders of consciousness were likely to recover consciousness.

Recent policy changes in the European Union have introduced the requirement for publicly funded research to be published in open access. This can be seen as part of a mode of democratic accountability that not only promotes transparency but also, Naomi Hodgson argues, is constituted by visibility and openness. By drawing attention to the way in which the researcher is asked to understand herself in this policy context, Hodgson illustrates how particular technologies of performance measurement and management, and of (...) publication, enter the researcher into this economy of visibility. The understanding of openness as a corrective to the traditional closed access system of publishing and the marketization of academia is challenged, then, in this article, which indicates how these technologies of reading and writing constitute the researcher as a particular figure in the emergent mode of governance.

This paper compares four techniques for measuring the masses of galaxies and larger astrophysical systems from their dynamics. The apparent agreement of these techniques is sometimes invoked as reason for hypothesizing the existence of huge quantities of “dark matter” as the best solution to “the dynamical discrepancy”, the 100-fold disparity between the amount of mass visible in large scale astrophysical systems and the amount calculated from dynamics. This paper argues that the agreement, though suggestive, is not definitive. The coincident measurements (...) remain the best reason for preferring dark matter over revisions to General Relativity for solving the dynamical discrepancy, but the resulting warrant for this preference is weak.

The world of work is undergoing major surgery. Future economic historians may yet describe the cumulative impact of globalisation, technological change and new work patterns that are currently shaking the OECD countries as an economic revolution similar in magnitude and significance to the industrial revolution of the 19th century. There is certainly plenty of pain around, but scattered in so many countries and cultures that this late 20th century revolution will probably prove to have been beyond the capacity of any (...) Charles Dickens, or of a Marx and Engels, to chronicle.From the perspective of the European Union, the pain is clearly visible in two areas: a growing insecurity and stress attending many who are at work in the Union, particularly in occupations and employments where earnings have risen a lot; and the level and persistence of long-term unemployment together with the growing number of discouraged workers, primarily men, who are opting out of the labour force altogether. Not visible within the EU, but no less real of course, is the impact on workers in other countries when the Union adopts protectionist or aggressive trading policies.[...]CONCLUSION :The dislocation that is evident throughout the world of work today, and the insecurity and pain it is causing, is influencing political life in the European Union. What Americans would call the ‘feel bad’ factor tempts some to support protectionist measures, abrupt limits to immigration, cuts in taxation and social services, workfare or — if they are outsiders — abuse of the social welfare system and black market activity. It is important to appreciate that very few people are escaping; the upheavals in the world of work are affecting insiders and outsiders. Making common cause requires forging a fresh consensus on fundamental values of which two key ones are the nature of a business enterprise and the place of a job in a person’s life. These are the key areas where social innovation must match the apparently ceasless innovations on the part of technology. They may, hopefully, prove capable of redirecting the process of technological change itself. (shrink)

continent. 1.4 (2011): 253—278. A Sense of French Politics Politics itself is not the exercise of power or struggle for power. Politics is first of all the configuration of a space as political, the framing of a specific sphere of experience, the setting of objects posed as "common" and of subjects to whom the capacity is recognized to designate these objects and discuss about them.(1) On April 14, 2011, France implemented its controversial ban of the niqab and burqa , commonly (...) referred to as the Islamic veil, in public places. On the coattails of the 2004 prohibition of religious artifacts, including the less concealing hijab or Islamic headscarves, in schools, the veil ban sparked equal outrage across both political and theological spectra, and many on both sides of the debate were quick to inquire about enforcement. As Steven Erlanger reports, “The police do not have the authority under the law to remove full veils, only to fine or require citizenship lessons for those who violate the new law.”(2) While the legal and social implications of this interdiction are ripe for study, the reprisals for breaking the law, notably compulsory citizenship classes, illuminate the strategic governmentality underlying the French government's targeting of the Muslim community, particularly those elements it considers affiliated with fundamentalist factions and/or terrorist organizations, if only through fashion—an integral component of French citizenship. Indeed, in allowing the (fashion) police to mandate instructional courses in citizenship for offenders, France implies that any Muslim choosing to wear the niqab or burqa , perhaps even for those who are already citizens, must not be aware of the subtle nuances of dress indicative of the French citizenry within public space. Furthermore, the degree of instruction requisite to citizenship, which clearly can and must be updated as the state sees fit, cements the imagined relation between citizens and states within the discourses on the veil ban. As Sharma contends, “Concepts of citizenship are the ideological glue that bonds the nation to the state. Citizenship provides the legal framework through which the state performs its role as ruler for the nation.”(3) Speaking for/as the state, French President Nicolas Sarkozy declared in a 2009 presentation before members of the government and other citizens that the burqa “is not welcome on the territory of France.”(4) Although there is nothing unique, especially recently, about a nation-state taking extreme measures to guard itself against what it deems to be threats to its sovereignty, the way in which the ongoing discourses on hijab have (d)evolved, which coincide with recent pronouncements by governmental leaders in Germany, Britain, and France that policies of multiculturalism have “failed,”(5) points toward nationalist reterritorializations, which is also to say physical and ideological re-appropriations, of public space within democratic milieux, which remain predicated upon the mediation of spaces. As Panagia deduces from Rancière, “Democracy […] is not an institutional form of government […], but an appearance whose visibilities and audibilites arise out of the dissonant blur of the everyday.”(6) Ultimately, the veil ban represents a calculated move to regulate the every day, which is to say the micropolitics of, that which is visible and invisible within French society, which makes it nothing short of a struggle to manage (the sensation of) bodies. Re-situating the political within the context of sense, Rancière argues that the fundamental essence of politics lies within the distinction between consensus and dissensus , and whereas most consider politics proper as fundamentally concerned with the fluid operations of the state— consensus , Rancière actually locates the political within events that disrupt the normative sensory order of things— dissensus . He explains, “Politics revolves around what is seen and what can be said about it, around who has the ability to see and the talent to speak, around the properties of spaces and the possibilities of time.”(7) This reformulation of politics centers on agency and, albeit perhaps unintended, representationality and offers a useful formulation for spatializing the discourses surrounding the Islamic veil, which are mired within seemingly senseless policies and practices of objectification. Instituting a normative “regime of visibility,” the French veil ban encapsulates the political economy of agency, now both mediated and representational, under the rule of nationalist governmentalities in increasingly transnational contexts.(8) Adjudicating presence within public space signals a concern with the sensory aspects of agency itself—what Rancière terms the “distribution of the sensible,” which is “a matrix that defines a set of relations between sense and sense: that is, between a form of sensory experience and an interpretation which makes sense of it.”(9) To be concerned with sense is to focus upon the body, and this somatic repositioning of the (fashionable) citizen within the territory of the state augurs the resurgence of nationalist bio-politics within Europe, since, as Hage explicates, “Nationalism, before being an explicit practice or a mode of classification, is a state of the body. It is a way of imagining one's position within the nation and what one can aspire to as a national.”(10) The French government's attempt to make (bodily) sense of public space for its citizens by and through policies aimed against a burqa-clad Muslim minority, which might only apply to “less then 400 to fewer than 2,000” women(11), reveals the necessary, yet mercurial, transmutation of public space into national space through bio-political strategies of sense-making, which, as Hage observes, denotes that “nationalists perceive themselves as spatial managers.”(12) At the center of this concern over public space is the equally contentious dimension of governing female Islamic identity, which has become one of the main critiques levied against Islam from outsiders who view the veil in its various forms as a clear sign of the religion's actual and symbolic violence against women, even if such critiques remain ensconced within nationalist discourses. As Halim and Meyers argue, “Although Western news media may focus their coverage of Muslim women on the debate over whether and the extent to which the veil may by oppressive to the women who wear it, they have exhibited little interest in the physical oppression of violence against women in Islamic countries.”(13) While it falls outside of the scope of this analysis to arbitrate all of the dimensions of this debate, understanding some of the issues related to female identity and hijab within public space are crucial to this study. As these topics are extraordinarily complex, even and perhaps especially within the Muslim community, it is necessary to provide some context concerning the value, purpose, and meaning of the Islamic veil, which has a rich and arduous history. The Art of the Veil At present, there are only two countries, Iran and Saudi Arabia, that require women to wear hijab , which is a decidedly problematic term and concept whose locus is itself caught within a struggle of sensation. Noting the strategic reterritorialization of the term, Berger explains: The choice of the name, hijab , now widely adopted to designate the “Islamic veil,” it itself interesting, although the semantic shift it operates is not directly commented upon by its users. Although the design (both the cut and the symbolic function) of the hijab and the Iranian chador are indeed the same, as opposed, for instance, to the traditional Algerian haik , the word hijab has come to replace the term chador popularized by the Iranian revolution, as a properly Arabic (hence Koranic) designation. This discursive shift points to the successful reclaiming of the national revolution in Iran by a transnational pan-Islamic movement, whose language of reference can only be Koranic Arabic.(14) While the hijab is certainly a point of contention within various countries dealing with immigrant Islamic populations (of which France has the largest in Europe as part of its colonial legacy in Algeria), it is clear that the veil is a historically contextualized artifact of Muslim identity with a variety of manifestations, even as forces outside of and within Islam seek to codify its actual and symbolic value. Ultimately, the varieties of hijab , including the full-faced burqa and niqab , are complex assemblages of meaning that speak to the multitudinous flows of Islamic identities over time and space. As Gökariksel and McLarney observe, “Wearing a certain style of veil may simultaneously be a disciplinary practice crucial to the cultivation of piety (Mahmood 2005; Gokariksel 2009) and a gendered performance of social distinction in terms of class, taste, and urbanity (White 1999; Navaro-Yashin 2002; Gokariksel and Secor 2009) or of ethnicity and race (Dwyer 1999).”(15) The ideological marketplace from which the varieties of hijab ebb and flow serves both as a reflection of the ever-present materiality and dynamic functionality of spiritual economies, which are derivative of the equally ubiquitous flows of transnational capital driving agency and representationality within our historical moment. Keeping these dual, yet deeply interconnected, capital ecologies as the site of exploration for how the veil is represented within public space, one might begin to sense what lurks behind such veiled agendas. Examining the symbolic and representational nature of the Islamic “veil” in its various forms, this project situates the decidedly political contestations of public space at stake in the French ban alongside recent condemnations of multiculturalism as calculated efforts to re-distribute the sensible so as to valorize national identity within increasingly transnational and globalized socio-economic spaces, which collapse exchange values between distinct, yet interwoven, economies of (cultural/material/spiritual) capital. As the discourses on the veil rely upon representational imag(in)ings, it seems fitting to explore the political economy and art of the veil through the phenomenon of street art, which, much like hijab , is a complex assemblage of meaning of sensation mired in representationality and capital exchange. As street artists have taken up hijab in various forms, the movement offers a lens with which to situate critical responses to the veil debate across both spiritual and material economies. Situating this street art both aesthetically and historically, Lewisohn explains, “'Street art' is a sub-genre of graffiti writing and owes much to its predecessor. Though there is a good deal of crossover between the genres, they are distinct and separate in their own right.”(16) Evolving out of the graffiti explosion of the late 1970's and 1980's, street art broke the unspoken rules of the artistic underground by challenging and re-examining one's sensory experience of art in public space by experimenting with both content and form in ways that harken back to the Situationist International, which as a collective challenged one's experience of urban space through various media and experiential phenomena. Again, Lewisohn observes, “It's important to note street art's break with the tradition of the tag, and its focus on visual symbols that embrace a much wider range of media than graffiti writers would use.”(17) From stencils to prints and murals to one-liners, street artists developed a reputation for critical social and political commentary, and while it is certainly the case that not all street art is intentionally political, in challenging the normative “regime of visibility,” as Rancière puts it, of public space, street artists—even if unconsciously—call into question the common sensory experience of the politics underlying the formation of (nationalist) space.(18) Indeed, Rancière refers to the partisan sensory managers as “police,” who ultimately forge “the rules governing the circulation of appearances, of their visibility and audibility, and the proper distribution of bodies therein.”(19) As such, one can sense that street art's relationship with the police is tenous for a variety of reasons. Writing about his own experience as a street artist, Shepard Fairey observes, “With street art, there's no committee deciding whether I can put my work up on the street, there's no censorship, and I have total freedom of expression, and that concept of freedom is expressed just by using the street as a medium.”(20) As Fairey and other street artists demonstrate, the medium, to paraphrase Marshall McLuhan, is the most glaring aspect of street art's message, and even as it now finds itself in galleries and usurped by private collectors, the ethos of the movement remains relavent to politics as it is, first and foremost, concerned with the configuration and experience of space. Just as examining the punishments for breaking the veil ban can map the terrain of French politics, a representational genealogy of street artist's deployment of hijab and female Muslim identity can assist in mining the depths of public space as a site of bio-political control and contestation in light of recent events in France and the rising tide of anti-multiculturalist rhetoric across Europe, even though the Islamic presence there is radically heterogenous. Using the work of Shepard Fairey, Princess Hijab, br1, and Banksy, this paper sets out to answer a number of key questions concerning the deployment of hijab, and female Islamic identity in particular, within street art as a movement now integral to and critical of the economies of exchange underlying global capitalism, which as a force of influence cannot be underestimated as a driver in the resurgence of nationalist biopolitical governmentalities. Although there exists a litany of artists to choose from, the aforementioned quartet of designers integrate hijab into their work in a seminal and critical fashion, and all have been working with the veil in some way prior to the French ban, which grants some additional context to their usage of it as a symbol in regards to the breakdown of multiculturalism across Europe, even if unconsciously. Although each artist depicts various amalgamations of hijab in their respective corpus, they share common tropes that raise significant questions concerning the veil debate, namely: what are the conditions of possibility for hijab to become a marker of Islamic identity within public space? How can we make sense of the representational topologies within street art's utilization of the hijab and female Islamic identity in light of the French ban? How might these aesthetic imag(in)ings simultaneously inhabit and combat normative discourses concerning hijab , multiculturalism, female Islamic identity, and public space? With these considerations as a backdrop, it is first necessary to outline more fully the hijab as a representative marker of female Islamic identity. The (Veiled) Writing on the Wall

Despite the importance of greetings for opening social interactions, their multimodal coordination processes remain poorly understood. We used a naturalistic, lab‐based setup where pairs of unacquainted participants approached and greeted each other while unaware their greeting behavior was studied. We measured the prevalence and time course of multimodal behaviors potentially culminating in a handshake, including motor behaviors (e.g., walking, standing up, hand movements like raise, grasp, and retraction), gaze patterns (using eye tracking glasses), and speech (close and distant verbal salutations). (...) We further manipulated the visibility of partners’ eyes to test its effect on gaze. Our findings reveal that gaze to a partner's face increases over the course of a greeting, but is partly averted during approach and is influenced by the visibility of partners’ eyes. Gaze helps coordinate handshakes, by signaling intent and guiding the grasp. The timing of adjacency pairs in verbal salutations is comparable to the precision of floor transitions in the main body of conversations, and varies according to greeting phase, with distant salutation pair parts featuring more gaps and close salutation pair parts featuring more overlap. Gender composition and a range of multimodal behaviors affect whether pairs chose to shake hands or not. These findings fill several gaps in our understanding of greetings and provide avenues for future research, including advancements in social robotics and human−robot interaction. (shrink)

Despite devoting their time to another person’s needs, many carers paradoxically experience guilt during their caregiving tenure concerning whether they are providing enough care. When discussing the “enough” of anything, what is at stake is that thing’s quantification. Given that there are seemingly no quantifiable units of care by which to measure the role, concerns regarding whether enough care is being provided often focus on what constitutes enough time as a carer. In exploring this aspect of the carer’s experience, two (...) key parameters emerge; guilt, and, quantified time. The guilt that carers report regarding whether they devote “enough time” to their caring responsibilities can be examined through Henri Bergson’s philosophical conception of quantification. By integrating contemporary analyses of carers’ guilt from the social sciences, most significantly via the sociology of Rebecca Olson, the relationship between quantified time and guilt becomes apparent. A quantified conception of time frames the assumption that spending more time on caregiving will reduce the amount of guilt felt by a carer. However, whilst care is structured according to quantified, clocked and calendared time, there are not comparable, quantifiable parameters for guilt. This means that suppositions of an inverse relationship between how much time one spends giving care, and how much guilt they will feel in terms of their caregiving, are problematic. These insights become relevant to health care policies via a coherence with calls to make the role of unpaid, caregiving, labour time more visible, and by explaining how understanding quantified time can help policies guide how caregivers negotiate guilt.

Heidegger writes that “metaphysical thinking rests on the distinction between what truly is and what, measured against this, constitutes all that is not truly in being.”3 In the long history of philosophy, this distinction has been variously interpreted. Generally, however, it has involved taking the true world as invisible yet intelligible and the nontrue world as visible but not per se intelligible. To illustrate this point, four examples should suffice. I will limit myself to Plato’s, Descartes’, Berkeley’s and Kant’s expression (...) of this distinction. For Plato, “the very being of to be——is to be “always in the same manner in relation to the same things.” As Plato explains, this is to be “unchanging” and, thus, to remain the same with oneself.

The Covid-19 pandemic broke on a world whose grip on epistemic trust was already in disarray. The first months of the pandemic saw many governments publicly performing reliance on epidemiological and modelling expertise in order to signal that data would be the basis for justifying whatever population-level measures of control were judged necessary. But comprehensive data has not become available, and instead scientists, policymakers and the public find themselves in a situation where policy inputs determine the data available and (...) vice versa. This essay asks how we can live with what Amoore has termed ‘post-Cartesian doubt’ in situations of existential risk, and what kind of approach to science and data can answer the moral and human demands of a situation such as the Covid-19 pandemic. I suggest that science and policy could be able to control the pandemic better by addressing the sources of uncertainty and missing data not as gaps in the information landscape, but as individuals who are likely to be members of less-visible and less powerful groups including low-wage workers, the elderly, migrants, prisoners and others. This would shift both data use and policy toward an ethics of care, an embodied approach which asks what people need and how they behave in relation to each other, rather than how to manage population-level behaviour. This approach, I argue, is more appropriate for pandemic response than a utilitarian calculation of how many people each country should expect to lose as a result of the disease. (shrink)

In a cloud chamber, the quantum measurement problem amounts to explaining the first droplet in a charged-particle track; subsequent droplets are explained by Mott’s 1929 wave-theoretic argument about collision-induced wavefunction collimation. I formulate a mechanism for how the first droplet in a cloud chamber track arises, making no reference to quantum measurement axioms. I look specifically at tracks of charged particles emitted in the simplest slow decays, because I can reason about rather than guess the form that wave packets take. (...) The first visible droplet occurs when a randomly occurring, barely-subcritical vapor droplet is pushed past criticality by ionization triggered by the faint wavefunction of the emitted charged particle. This is possible because potential energy incurred when an ionized vapor molecule polarizes the other molecules in a droplet can balance the excitation energy needed for the emitted charged particle to create the ion in the first place. This degeneracy is a singular condition for Coulombic scattering, leading to infinite or near-infinite ionization cross sections, and from there to an emergent Born rule in position space, but not an operator projection as in the projection postulate. Analogous mechanisms may explain canonical quantum measurement behavior in detectors such as ionization chambers, proportional counters, photomultiplier tubes or bubble chambers. This work is important because attempts to understand canonical quantum measurement behavior and its limitations have become urgent in view of worldwide investment in quantum computing and in searches for super-rare processes.
