Laterally induced impedance effects in vision

A linear integral equation for a system of mutually impeding points is developed and solved explicitly. Particular solutions are shown to be subharmonic functions for a large class of stimuli. Specialized forms of the general equation presented in this paper occur within a number of mathematical models of Mach bands. In addition to these known spatial properties, our results also show that the time course of this basic equation may be useful in developing models of transient neural activity as well as of temporal psychophysical phenomena, such as the Broca-Sulzer effect. Further, a spatial transfer function much like the low-frequency cutoff of empirically derived modulation transfer functions follows directly from our basic integral equation if the additional assumption of spatial homogeneity is imposed.     

‘I think a little bit of a kick is sometimes what you need’: Women’s accounts of whole-body scanning and likely impact on health-related behaviours

Objective: This study was designed to investigate whether whole-body scanning might promote healthy eating and physical activity in women, and to explore the effects of scanning on body image.

Design: Fourteen women aged 22–45 years without histories of eating disorders or whole-body scanning took part in semi-structured interviews before and after scanning. Data were analysed using inductive thematic analysis.

Results: Scans did not look as expected, and participants expressed ‘surprise’ and ‘shock’. Participants focused on perceived negative aspects of their bodies as revealed in scan images, and agreed that women with body concerns would find scans too ‘real’ and ‘raw’. Eleven women who met UK Government physical activity and healthy eating guidelines reported that the scan provided additional motivation to maintain, and in nine cases to increase, those behaviours. Two women who neither exercised nor ate healthily would not increase physical activity or change their diets significantly following scanning.

Conclusion: Whole-body scanning may enable maintenance or even acceleration of physical activity and healthy eating, but is unlikely to be useful in promoting initiation of these behaviours. Participants engaged in unhelpful body critique when viewing scans; scanning needs to be confined to contexts where support is provided, to avoid increasing body-related concerns.     

Non‐Competitive Agency and Luther's Experiential Argument Against Virtue

This article examines a critique that has been levied against Martin Luther's account of the passivity of the human agent in salvation, and his corresponding critique of Aristotelian and Scholastic accounts of virtue. According to Reinhard Hütter and Jennifer Herdt, among others, Luther's theology of passivity is primarily the product of a philosophical failure to recognize that divine and human agency can be conceived in non‐competitive terms. This article demonstrates through close analysis of Luther's arguments that this philosophical critique does not succeed in refuting Luther's theology of passivity. This is because it fails to recognize that Luther's view of human agency and his critique of virtue are based to a significant degree on a different kind of argument: namely, empirical reflection on the experience of sin, including especially experience of the unmasterability of sinful affections through discipline, habit, or effort of will. I conclude by arguing that until Christian virtue ethicists have reckoned with this experiential argument, they have not engaged with one of the strongest theological critiques of virtue‐based paradigms of Christian moral transformation.     

The myth of a secular state: A study of religious politics with historical illustrations

Religion has continued to assert itself as a significant moral force in Nigeria's post‐independence politics; however, some recent studies of the country's political life tend to dismiss religion as a kind of mystical irrationality or an act of deluded trust. After conducting an audit of what I take to be the assets and the liabilities of the intellectual traditions underpinning this secularist preference, I propose a theory of political morality in which themes of legitimacy, identity and social justice are explained against the background of religious expectations. I argue that the rationale for political behaviour in Nigeria is not fully accounted for by the categories of class and ethnicity, but must be sought in a more inclusive and transcendent moral basis. I conclude that the recent high‐profile involvements of religious persons in politics should not be seen as flashes of political insanity; rather, they constitute genuine attempts to reformulate the modern language of public morality.     

A RESPONSE TO HANS LUCHT'S “VIOLENCE AND MORALITY: THE CONCESSION OF LOSS IN A GHANAIAN FISHING VILLAGE”

The violent encounter between Africans and the forces of globalization raises the question of whether Africans should capitulate to these forces or seek to morally transform them, notwithstanding the uncertainty of achieving success. This essay argues that an exclusively existentialist interpretation of the African predicaments is inadequate because it erects a false dichotomy between African religious and moral sensibilities. It proposes instead an ethic of responsibility that affirms the interdependence of not only these two realms of life, but also of communal well‐being and individual's subjectivity.     

Quality of Life,Personality and Use of Pain Medication in Patients with Chronic Back Pain

The aim of the study was to assess whether the functional disability and the quality of life in patients with chronic back pain was associated with some personality traits and whether the use of pain medication in patients with chronic back pain can be predisposed with some personality traits. The study sample comprised 262 older patients with chronic back pain of non-inflammatory origin. The level of disability related to chronic back pain was assessed by Roland-Morris Questionnaire, health-related quality of life was assessed by Short Form 36 and personality traits by Eysenck Personality Questionnaire. Among analyzed personality traits (psychoticism, extraversion, neuroticism, lie tendencies), only neuroticism significantly predicted self-reported disability caused by back pain. Patients on pain medication had significantly worse quality of life and disability caused by back pain, but they did not differ significantly in personality traits compared to patients without pain medication. There were no differences in disability due to back pain and in level of neuroticism between patients who had jobs with higher or lower physical demand. People with higher scores on neuroticism inclined more to report a lower functional disability and the quality of life caused by chronic back pain. Patients on pain medication reported more inferior physical than psychological concept of quality of life. Use of pain medication was not associated with personality traits assessed by Eysenck Personality Questionnaire. In our elderly patients with chronic back pain, lower quality of life was associated with elevated neuroticism score and more frequent use of pain medication.
