PurposeTo evaluate the relationship between intraocular straylight perception and: (i) contrast sensitivity (CS), (ii) halo size, and (iii) hazard recognition distance, in the presence and absence of glare.Subjects and methodsParticipants were 15 (5 female) ophthalmologically healthy adults, aged 54.6–80.6 (median: 67.2) years. Intraocular straylight (log s) was measured using a straylight meter (C-Quant; Oculus GmbH, Wetzlar, Germany). CS with glare was measured clinically using the Optovist I device (Vistec Inc., Olching, Germany) and also within a driving simulator using Landolt Cs. (...) These were presented under both static or dynamic viewing conditions, and either with or without glare. Hazard detection distance was measured for simulated obstacles of varying contrast. For this, the participant was required to maintain a speed of 60 km/h within a custom-built nighttime driving simulator. Glare was simulated by LED arrays, moved by cable robots to mimic an oncoming car’s headlights. Halo size (“halometry”) was measured by moving Landolt Cs outward originating from the center of a static glare source. The outcome measure from “halometry” was the radius of the halo (angular extent, in degrees visual angle).ResultsThe correlation between intraocular straylight perception, log s, and hazard recognition distance under glare was poor for the low contrast obstacles (leading/subdominant eye: r = 0.27/r = 0.34). Conversely, log CS measured with glare strongly predicted hazard recognition distances under glare. This was true both when log CS was measured using a clinical device (Optovist I: r = 0.93) and within the driving simulator, under static (r = 0.69) and dynamic (r = 0.61) conditions, and also with “halometry” (r = 0.70). Glare reduced log CS and hazard recognition distance for almost all visual function parameters.ConclusionIntraocular straylight was a poor predictor of visual function and driving performance within this experiment. Conversely, CS was a strong predictor of both hazard recognition and halo extent. The presence of glare and motion lead to a degradation of CS in a driving simulator. Future studies are necessary to evaluate the effectiveness of all above-mentioned vision-related parameters for predicting fitness to drive under real-life conditions. (shrink)

This paper presents a theoretical elaboration of the ethical framework of classical capitalism as formulated by Adam Smith in reaction to the dominant mercantilism of his day. It is seen that Smith's project was profoundly ethical and designed to emancipate the consumer from a producer and state dominated economy. Over time, however, the various dysfunctions of a capitalist economy — e.g., concentration of wealth, market power — became manifest and the utilitarian ethical basis of the system eroded. Contemporary capitalism, dominated (...) as it is by large corporations, entrenched political interests and persistent social pathologies, bears little resemblance to the system which Smith envisioned would serve the common man. Most critiques of capitalism are launched from a Marxian-based perspective. We find, however, that by illustrating the wide gap between the reality of contemporary capitalism and the model of amoral political economy developed by Smith, the father of capitalism proves to be the most trenchant critic of the current order.

Actions that financially benefit one person may present risk to another person. For example, the payment incentives of portfolio managers and investors are often asymmetrical such that actions that benefit a portfolio manager can pose financial risk to clients. Despite the presence and potential harm of these asymmetries, few have addressed the question of who exploits these asymmetries and how to mitigate potential harm. Our study examined the effect of selfish personality traits (the Dark Triad) and interpersonal bonding on decision-making (...) for the self, another person, and another person with under reward asymmetry present. Results demonstrated that individuals higher in narcissism and psychopathy made risky decisions for themselves. However, when reward asymmetries were present, all three Dark Triad traits were associated with making riskier decisions for another person in order to benefit the self. There was also a significant interaction between interpersonal closeness generated through bonding and psychopathy such that bonding made the decision-making processes of those high in psychopathy less risky for others. These findings have implications for how different individuals with different relationships make self and other-based financial decisions, and how those decisions change when rewards are asymmetrical.

Interest is growing in the relocalization of staple crops, including wheat, in western Washington (WWA), a nontraditional wheat-growing area. Commercial bakers are potentially important food chain intermediaries in the case of relocalized wheat production. We conducted a mail survey of commercial bakers in WWA to assess their interest in sourcing wheat/flour from WWA, identify the characteristics of bakeries most likely to purchase wheat/flour from WWA, understand the factors important to bakers in purchasing regionally produced wheat/flour, and identify perceived barriers to (...) making such purchases. Sixty-one percent of survey respondents were interested in purchasing WWA wheat/flour. Bakers who used retail strategies to market their products were more likely to be interested in WWA wheat/flour compared to those not using retail methods. Bakers’ current purchases of Washington wheat/flour were not related to their interest in purchasing WWA flour. The most important factors bakers would consider in purchasing regionally produced wheat/flour were consistency of flour quality, quality of flour, and reliability of supply. Cost was the most frequently mentioned barrier to the purchase of regionally produced wheat/flour. Our results are relevant for other areas attempting to reconnect grain producers, commercial bakers, and consumers in mutually beneficial ways. (shrink)

Passivity experiences in schizophrenia are thought to be due to a failure in a neurocognitive action self-monitoring system . Drawing on the assumption that inner speech is a form of action, a recent model of auditory verbal hallucinations has proposed that AVHs can be explained by a failure in the NASS. In this article, we offer an alternative application of the NASS to AVHs, with separate mechanisms creating the emotion of self-as-agent and other-as-agent. We defend the assumption that inner speech (...) can be considered as a form of action, and show how a number of previous criticisms of applying the NASS to AVHs can be refuted. This is achieved in part through taking a Vygotskian developmental perspective on inner speech. It is suggested that more research into the nature and development of inner speech is needed to further our understanding of AVHs. (shrink)

The proposal that there is an illusion of conscious will has been supported by findings that priming of stimulus location in a task requiring judgements of action-authorship can enhance participants’ experience of agency. We attempted to replicate findings from the ‘Wheel of Fortune’ task [Aarts, H., Custers, R., & Wegner, D. M. . On the inference of personal authorship: enhancing experienced agency by priming effect information. Consciousness and Cognition, 14, 439–458]. We also examined participants’ performance on this task in relation (...) to self-reported passivity experiences and hallucination-proneness. We found a significant effect of priming, with primes being found to increase the experience of agency. An interaction between gender and priming was also found, with priming enhancing feelings of agency in women but not in men. There were no significant correlations between levels of self-reported passivity experiences or hallucination-proneness and participants’ susceptibility to the priming effect on ratings of agency. Implications of these findings are discussed with regard to a prominent model of passivity experiences. (shrink)

The different ways in which the three medieval societies of Byzantium, Latin Christendom, and Islam institutionalized the charitable impulse present in their respective faiths reflected the fundamentally different religious values which motivated these civilizations as well as their different levels of material and intellectual development. All three societies exalted the relief of human suffering, especially the care of the sick, as a religiously sanctioned gesture; and all three invented or adopted institutional means for attaining this pious objective. The various medieval (...) counterparts of the modern “hospital”—the Byzantine nosocomeion or xenodocheion, the European hospitale, and the Islamic maristan—differed significantly, however, with respect to their organization and operation, the clientele which they served, and the ultimate intent of their charitable efforts. Accordingly, a comparison of these social welfare institutions reveals the contrasting ways in which the two Christendoms and Islam defined and applied the ideals of “piety” and “charity” during the middle ages.

Birds, beasts, and creeping things swarm throughout the Bible's pages. Despite their prevalence, most biblical scholars have viewed them merely as metaphors, passive objects, or background embellishment to the human experience. This collection seeks to move beyond this traditional view of biblical animals by engaging the growing interdisciplinary field of animal studies. Contributors Peter Joshua Atkins, Jared Beverly, William P. Brown, Margaret Cohen, Jacob R. Evers, Michael J. Gilmour, William "Chip" Gruen, Dong Hyeon Jeong, Brian Fiu Kolia, Anne Létourneau, Robert (...) R. MacKay, Suzanna R. Millar, Timothy J. Sandoval, Robert Paul Seesengood, Ken Stone, Brian James Tipton, Arthur W. Walker-Jones, and Jaime L. Waters showcase the breadth and depth of inquiry that animal studies can foster in biblical studies as well as what animal studies can gain from a more rigorous engagement with biblical texts. Together the essays offer an animal hermeneutic that supports the flourishing of all creatures. (shrink)

David Conner’s 2022 AFHVS Presidential Address discusses the importance for transdisciplinary partnerships among varied scholars and the co-creation of new knowledge. He suggests that without such co-creation, we will fail to solve wicked problems such as food system sustainability. In this essay, Kelinsky-Jones focuses on requisite changes among universities and federal funding alike to advance food system transformation sustainability and equitably. She argues that without prioritizing transdisciplinary partnerships grounded in principles of epistemic inclusion, we will fail to envision and (...) enact requisite food system transformation. Kelinsky-Jones directs her argument first toward land grant universities by urging them to prioritize agroecology as a transdisciplinary approach of pursuing epistemically inclusive science with society. She offers recommendations for teaching, research, and extension practice. Subsequently, recognizing that funders and universities often work in tandem, Kelinsky-Jones closes with three recommendations derived from her research for how the United States Agency for International Development may equally support and prioritize agroecology.

Recognising and responding appropriately to emotions is critical to adaptive psychological functioning. Psychopathic traits (e.g. callous, manipulative, impulsive, antisocial) are related to differences in recognition and response when emotion is conveyed through facial expressions and language. Use of emotional music stimuli represents a promising approach to improve our understanding of the specific emotion processing difficulties underlying psychopathic traits because it decouples recognition of emotion from cues directly conveyed by other people (e.g. facial signals). In Experiment 1, participants listened to clips (...) of emotional music and identified the emotional content (Sample 1, N = 196) or reported on their feelings elicited by the music (Sample 2, N = 197). Participants accurately recognised (t(195) = 32.78, p <.001, d = 4.69) and reported feelings consistent with (t(196) = 7.84, p <.001, d = 1.12) the emotion conveyed in the music. However, psychopathic traits were associated with reduced emotion recognition accuracy (F(1, 191) = 19.39, p <.001) and reduced likelihood of feeling the emotion (F(1, 193) = 35.45, p <.001), particularly for fearful music. In Experiment 2, we replicated findings for broad difficulties with emotion recognition (Sample 3, N = 179) and emotional resonance (Sample 4, N = 199) associated with psychopathic traits. Results offer new insight into emotion recognition and response difficulties that are associated with psychopathic traits. (shrink)

In his book, Theory of Knowledge , Roderick Chisholm distinguishes very precisely between, amongst others, what he calls acceptable, reasonable and evident propositions. A proposition is acceptable if with-holding it is not more reasonable than believing it; a proposition is reasonable if believing it is more reasonable than with-holding it; and a proposition is evident for a person provided it is reasonable for him, and there is no other proposition such that the latter is more reasonable than the former. The (...) notion of being more reasonable is obviously pivotal, and Chisholm explains what it is for an attitude to be more reasonable than another in the following words: “If the person in question were a rational being, if his concerns were purely intellectual, and if he were to choose between the two attitudes, then he would choose the more reasonable in preference to the less reasonable”. The wording of this conditional suggests that Chisholm does not think a person is necessarily rational, so it is imperative that we ask: When is a person rational? (shrink)

There is a significant lack of diversity in philosophy, including an underrepresentation of women and people of color, and a dearth of philosophy programs that offer classes exploring philosophy outside the Western canon. This problem is further compounded by institutional racism, sexism, and ableism within philosophy pedagogy and practice and the perception that philosophy is an abstract subject suitable only for academically advanced students. If philosophy were made more accessible to a diverse group of students before they entered college, would (...) it be possible to recruit more individuals from underrepresented groups into the field? In 2018, PLATO and the APA surveyed their members about their first exposure to philosophy. It was clear that early experiences—conversations with friends and family, books in grade school, and classes in high school—were pivotal moments that generated interest in philosophy. In this paper we describe some of these experiences and suggest that P4C programs, if done well, have the potential to help build a robust and inclusive K–12 to college philosophy pipeline by tapping into the natural interest children have in philosophical wondering.

Objective: To determine whether the marks in the third year Objective Structured Clinical Examination were affected by the collusion reported by the students themselves on an electronic discussion board.Design: A review of the student discussion, examiners’ feedback and a comparison of the marks obtained on the 2 days of the OSCE.Participants: 255 third year medical students.Setting: An OSCE consisting of 15 stations, administered on three sites over 2 days at a UK medical school.Results: 40 students contributed to the discussion on (...) the electronic discussion board. The main points raised were perceived inequity between students who did, or did not, have prior knowledge of the station content, and the lack of honesty and professionalism of their peers. Most contributors claimed to have received, or knew of others receiving, prior knowledge, but none confessed to passing on information. No significant difference was observed in the overall mark for the OSCE on day 1 ) and day 2 ). On day 2, marks were considerably greater for four stations and markedly lower for three stations. It was not obvious why collusion should affect these station marks. A clear indication of the effects of collusion could only be obtained from a single subsection of an individual station where 82 students on day 2 incorrectly gave the diagnosis from day 1.Conclusion: Marks do not provide a sound inference of student collusion in an OSCE and may mask the aspects of professional development of students.

The endowment of religious, charitable, and educational enterprises by the establishment of trusts in land, the income from which could be devoted to such uses, was an immensely popular form of pious expression in both medieval Christendom and the Islamic world. The motives for, and applications of such endowments differed markedly, however, between the two religious cultures. The endowment of prayers and masses for beneficiaries, living and dead, exemplified the sacramental and sacerdotal quality of pre-Reformation Christianity. This ritualistic and ecclesiastical (...) use of endowments in Latin Christian Europe and the Orthodox East, a use dependent on the existence of a sacramental system and an institutional church, contrasted sharply with the broader application of the Muslim waqf, by means of which pious individuals and groups sponsored a wide variety of charities, explicitly life-oriented and quite unconnected with a corporate clerical establishment. The infinite multiplication of private acts of charity by devout Muslims manifested the moralistic bent of Islam, which aspired to recast society according to the norms of the Qur'an and sacred law. The contrasting uses to which the two religious systems put the gifts and legacies of the faithful reflected the operation of fundamentally different religious premises, whereas the institutionalization of these premises in a shared legal fiction, the trust, assured their enforcement in society and life.
