Aphantasia is a recently discovered disorder characterised by the total incapacity to generate visual forms of mental imagery. This paper proposes that aphantasia raises important theoretical concerns for the ongoing debate in the philosophy and science of consciousness over the nature of dreams. Recent studies of aphantasia and its neurobehavioral correlates reveal that the majority of aphantasics, whilst unable to produce visual imagery while awake, nevertheless retain the capacity to experience rich visual dreams. This finding constitutes a novel explanandum for (...) theories of dreaming. Specifically, I argue that the recent dream reports of aphantasics constitute an empirical challenge to the emerging family of views which claim that dreams are essentially imaginative experiences, constitutively involving the kinds of mental imagery which aphantasics, ex-hypothesi, lack. After presenting this challenge in the context of Jonathan Ichikawa’s recent arguments for this view, I argue that this empirical challenge may be overcome if the imagination theorist abandons Ichikawa’s account of dreaming in favour of a modified version. This involves the claim that dreams are essentially inactive and constitutively involve non voluntary forms of imagination. I conclude with a suggestion for further research which can test the viability of this alternative hypothesis, and move the debate forward. (shrink)

The article examines the algorithms for JPEG and JPEG-2000 compression of various graphic images. The main steps of the operation of both algorithms are given, their advantages and disadvantages are noted. The main differences between JPEG and JPEG-2000 are analyzed. It is noted that the JPEG-2000 algorithm allows re-moving visually unpleasant effects. This makes it possible to highlight important areas of the image and improve the quality of their compression. The features of each step of the algorithms are considered and (...) the difficulties of their implementation are compared. The effectiveness of each algorithm is demonstrated by the example of a full-color image of the BSU emblem. The obtained compression ratios were obtained and shown in the corresponding tables using both algorithms. Compression ratios are obtained for a wide range of quality values from 1 to ten. We studied various types of images: black and white, business graphics, indexed and full color. A modified LZW-Lempel-Ziv-Welch algorithm is presented, which is applicable to compress a variety of information from text to images. The modification is based on limiting the graphic file to 256 colors. This made it possible to index the color with one byte instead of three. The efficiency of this modification grows with increasing image sizes. The modified LZW-algorithm can be adapted to any image from single-color to full-color. The prepared tests were indexed to the required number of colors in the images using the FastStone Image Viewer program. For each image, seven copies were obtained, containing 4, 8, 16, 32, 64, 128 and 256 colors, respectively. Testing results showed that the modified version of the LZW algorithm allows for an average of twice the compression ratio. However, in a class of full-color images, both algorithms showed the same results. The developed modification of the LZW algorithm can be successfully applied in the field of site design, especially in the case of so-called flat design. The comparative characteristics of the basic and modified methods are presented. (shrink)

Merab Konstantinovich [Mamardashvili] met with me immediately, as soon as I requested it, although he forewarned me that he could only dimly remember much of that distant past in which I was most interested. But evidently that past still perturbed him as well, since he agreed to speak with me even though he had not yet completely recovered from his illness, and hence his voice was feeble, at times subsiding to a whisper; he would pronounce his words indistinctly, constantly sticking (...) one onto another; on top of that, for technical reasons the dictaphone was situated a bit away from him. It was therefore very difficult to transcribe the text, and I raised many questions with the idea of asking Merab Konstantinovich about them at our next meeting and clearing up some things. But alas, there was no next meeting … Hence I am permitting myself now to publish only some of the most clearly enunciated fragments of my conversation with him, one of the four "forefathers" of the Moscow Methodological Circle, whose name for us, today's participants (and hence neophytes) in the methodological movement, is enveloped by legends handed down by word of mouth. I kept my questions to a minimum. Mamardashvili's reminiscences, arguments, and reflections will seem contentious to many. But no matter, one can dispute points of substance even with those who have passed on. (shrink)

Being building block of data sciences, link prediction plays a vital role in revealing the hidden mechanisms that lead the networking dynamics. Since many techniques depending in vertex similarity and edge features were put forward to rule out many well-known link prediction challenges, many problems are still there just because of unique formulation characteristics of sparse networks. In this study, we applied some graph transformations and several inequalities to determine the greatest value of first and second Zagreb invariant, S K (...) and S K 1 invariants, for acyclic connected structures of given order, diameter, and pendant vertices. Also, we determined the corresponding extremal acyclic connected structures for these topological indices and provide an ordering giving a sequence of acyclic connected structures having these indices from greatest in decreasing order.

Background One of the objectives of medicine is to relieve patients' suffering. As a consequence, it is important to understand patients' perspectives of suffering and their ability to cope. However, there is poor insight into what determines their suffering and their ability to bear it. Purpose To explore the constituent elements of suffering of patients who explicitly request euthanasia or physician-assisted suicide (EAS) and to better understand unbearable suffering from the patients' perspective. Patients and methods A qualitative study using in-depth (...) face-to-face interviews was conducted with 31 patients who had requested EAS. The grounded theory approach was used to analyse the data. Results Medical, psycho-emotional, socio-environmental and existential themes contributed to suffering. Especially fatigue, pain, decline, negative feelings, loss of self, fear of future suffering, dependency, loss of autonomy, being worn out, being a burden, loneliness, loss of all that makes life worth living, hopelessness, pointlessness and being tired of living were constituent elements of unbearable suffering. Only patients with a psychiatric (co)diagnosis suffered unbearably all the time. Conclusions Unbearable suffering is the outcome of an intensive process that originates in the symptoms of illness and/or ageing. According to patients, hopelessness is an essential element of unbearable suffering. Medical and social elements may cause suffering, but especially when accompanied by psycho-emotional and existential problems suffering will become ‘unbearable’. Personality characteristics and biographical aspects greatly influence the burden of suffering. Unbearable suffering can only be understood in the continuum of the patients' perspectives of the past, the present and expectations of the future. (shrink)

Judgment aggregation theory, which concerns the translation of individual judgments on logical propositions into consistent group judgments, has shown that group consistency generally cannot be guaranteed if each proposition is treated independently from the others. Developing the right method of abandoning independence is thus a high-priority goal. However, little work has been done in this area outside of a few simple approaches. To fill the gap, we compare four methods based on distance metrics between judgment sets. The methods generalize the (...) premise-based and sequential priority approaches to judgment aggregation, as well as distance-based preference aggregation. They each guarantee group consistency and implement a range of distinct functions with different properties, broadening the available tools for social choice. A central result is that only one of these methods (not previously considered in the literature) satisfies three attractive properties for all reasonable metrics. (shrink)

This 1990 collection explores one recurrent theme connecting philosophy and politics: the relation between the nature of man and the structure of society. It does so by concentrating on the topical issue of the market economy as an attempt to resolve the clash between individual autonomy and collective action. Beginning with a historical and personal recollection by Enoch Powell and a response by Robert Skidelsky, the volume then provides a forum for political theorists and philosophers to take issue on the (...) fundamental topics of markets and morals; liberal man; and equality and libertarianism. It succeeds equally as a stimulating textbook and a book for the general reader who wishes to understand the philosophical issues arising in a market economy. (shrink)

The notion of a Sasaki projectionon an orthomodular lattice is generalized to a mapping Φ: E × E → E, where E is an effect algebra. If E is lattice ordered and Φ is symmetric, then E is called a Φ-symmetric effect algebra.This paper launches a study of such effect algebras. In particular, it is shown that every interval effect algebra with a lattice-ordered ambient group is Φ-symmetric, and its group is the one constructed by Ravindran in his proof that (...) every effect algebra that has the Riesz decomposition property is an interval algebra. It is shown that the doubling construction introduced in the paper is connected to the conditional event algebrasof Goodman, Nguyen, and Walker. (shrink)

There is no doubt that custard apple diseases are among the important reasons that destroy the Custard Apple plant and its agricultural crops. This leads to obvious damage to these plants and they become inedible. Discovering these diseases is a good step to provide the appropriate and correct treatment. Determining the treatment with high accuracy depends on the method used to correctly diagnose the disease, expert systems can greatly help in avoiding damage to these plants. The expert system correctly diagnoses (...) Custard Apple disease to make it easier for farmers to find the right treatment based on the appropriate diagnosis. Objectives: A specialized syllable language system was established for the diagnosis of Custard Apple plant disease. (shrink)

Are values and social priorities universal, or do they vary across geography, culture, and time? This question is very relevant to Asia’s emerging economies that are increasingly looking at Western models for answers to their own outmoded health care systems that are in dire need of reform. But is it safe for them to do so without sufficient regard to their own social, political, and philosophical moorings? This article argues that historical and cultural legacies influence prevailing social values with regard (...) to health care financing and resource allocation, and that the Confucian dimension provides a helpful entry point for a deeper understanding of ongoing health care reforms in East Asia – as exemplified by the unique case of Singapore.

Background: Hospital nurses are frequently the first care givers to receive a patient’s request for euthanasia or physician-assisted suicide (PAS). In France, there is no consensus over which medical practices should be considered euthanasia, and this lack of consensus blurred the debate about euthanasia and PAS legalisation. This study aimed to investigate French hospital nurses’ opinions towards both legalisations, including personal conceptions of euthanasia and working conditions and organisation. Methods: A phone survey conducted among a random national sample of 1502 (...) French hospital nurses. We studied factors associated with opinions towards euthanasia and PAS, including contextual factors related to hospital units with random-effects logistic models. Results: Overall, 48% of nurses supported legalisation of euthanasia and 29%, of PAS. Religiosity, training in pallative care/pain management and feeling competent in end-of-life care were negatively correlated with support for legalisation of both euthanasia and PAS, while nurses working at night were more prone to support legalisation of both. The support for legalisation of euthanasia and PAS was also weaker in pain treatment/palliative care and intensive care units, and it was stronger in units not benefiting from interventions of charity/religious workers and in units with more nurses. Conclusions: Many French hospital nurses uphold the legalisation of euthanasia and PAS, but these nurses may be the least likely to perform what proponents of legalisation call “good” euthanasia. Improving professional knowledge of palliative care could improve the management of end-of-life situations and help to clarify the debate over euthanasia. (shrink)

This paper inquires into the nature of intertheoretic relations between psychology and neuroscience. This relationship has been characterized by some as one in which psychological explanations eventually will fall away as otiose, overthrown completely by neurobiological ones. Against this view it will be argued that it squares poorly with scientific practices and empirical developments in the cognitive neurosciences. We analyse a case from research on visual perception, which suggests a much more subtle and complex interplay between psychology and neuroscience than (...) a complete take-over of the former by the latter. In the case of vision, cross-theory influences between psychology and neuroscience go back and forth, resulting in refinement in both disciplines. We interpret this case study as showing that: (1) Mutual co-evolution of psychological and neurobiological theories, exemplifying persisting top-down influences from psychology, is a more empirically adequate way to describe psychoneural theory relations than a view on co-evolution, favoured by reductionists, which regards the cross-theory contributions from psychology as merely heuristically useful with no enduring influence on neurobiological theorizing; (2) In research on vision, discovering (or hypothesizing) the neural basis of functions vindicates psychological approaches, it does not eliminate them; (3) Current work on vision shows that many perceptual phenomena must be understood in terms of dynamical interactions between an observer and his/her environment. Therefore, we argue that internalist characterizations of the visual system must be supplemented with externalist accounts that address these reciprocal observer-environment interactions involved in vision. Such processes seem quite different from (internal) cellular and molecular ones, and as such seem to lie outside the scope of neuroscientific inquiry. We conclude that psychoneural reduction or elimination is implausible as a meta-theoretical prediction of theory choice in empirical work. Instead, this case study of vision shows that both psychology and neuroscience contribute to, and complement one another in the study of visual perception. (shrink)

Using the mathematical notion of an entity to represent states in quantum and classical mechanics, we show that, in a strict sense, proper superpositions are possible in classical mechanics.

This paper concludes a special feature of Sustainability Science that explores a broad range of social value theoretical traditions, such as religious studies, social psychology, indigenous knowledge, economics, sociology, and philosophy. We introduce a novel transdisciplinary conceptual framework that revolves around concepts of 'lenses' and 'tensions' to help navigate value diversity. First, we consider the notion of lenses: perspectives on value and valuation along diverse dimensions that describe what values focus on, how their sociality is envisioned, and what epistemic and (...) procedural assumptions are made. We characterise fourteen of such dimensions. This provides a foundation for exploration of seven areas of tension, between: (1) the values of individuals vs collectives; (2) values as discrete and held vs embedded and constructed; (3) value as static or changeable; (4) valuation as descriptive vs normative and transformative; (5) social vs relational values; (6) different rationalities and their relation to value integration; (7) degrees of acknowledgment of the role of power in navigating value conflicts. In doing so, we embrace the 'mess' of diversity, yet also provide a framework to organise this mess and support and encourage active transdisciplinary collaboration. We identify key research areas where such collaborations can be harnessed for sustainability transformation. Here it is crucial to understand how certain social value lenses are privileged over others and build capacity in decision-making for understanding and drawing on multiple value, epistemic and procedural lenses.

Corruption involves greed, money, and risky decision-making. We explore the love of money, pay satisfaction, probability of risk, and dishonesty across cultures. Avaricious monetary aspiration breeds unethicality. Prospect theory frames decisions in the gains-losses domain and high-low probability. Pay dissatisfaction (in the losses domain) incites dishonesty in the name of justice at the individual level. The Corruption Perceptions Index, CPI, signals a high-low probability of getting caught for dishonesty at the country level. We theorize that decision-makers adopt avaricious love-of-money aspiration (...) as a lens and frame dishonesty in the gains-losses domain (pay satisfaction-dissatisfaction, Level 1) and high-low probability (CPI, Level 2) to maximize expected utility and ultimate serenity. We challenge the myth: Pay satisfaction mitigates dishonesty across nations consistently. Based on 6500 managers in 32 countries, our cross-level three-dimensional visualization offers the following discoveries. Under high aspiration conditions, pay dissatisfaction excites the highest- (third-highest) avaricious justice-seeking dishonesty in high (medium) CPI nations, supporting the certainty effect. However, pay satisfaction provokes the second-highest avaricious opportunity-seizing dishonesty in low CPI entities, sustaining the possibility effect—maximizing expected utility. Under low aspiration conditions, high pay satisfaction consistently leads to low dishonesty, demonstrating risk aversion—achieving ultimate serenity. We expand prospect theory from a micro and individual-level theory to a cross-level theory of monetary wisdom across 32 nations. We enhance the S-shaped Curve to three 3-D corruption surfaces across three levels of the global economic pyramid, providing novel insights into behavioral economics, business ethics, the environment, and responsibility.

The description Ausonius has given us of his family and of the teachers and professors of Bordeaux in the mid-fourth century is exceptional among our sources because of its detail and completeness. There is no reason to suppose that the picture he gives is untypical of life in the provinces and it makes a welcome change from the histories of aristocratic politics at Rome or Constantinople. It provides an excellent opportunity for a pilot study in which we may see how (...) the conflicting elements of social status were in practice reconciled and applied. In the traditional, and still prevalent view, the society of the Later Roman Empire was ‘crushed … in the iron clamp of castes separated from one another by barriers which could not be passed’. The evidence of Ausonius suggests that this judgement should be qualified. The society of the fourth century may have been stable. It was not static. (shrink)

The neural representation of a repeated stimulus is the standard against which a deviant stimulus is measured in the brain, giving rise to the well-known mismatch response. It has been suggested that individuals with dyslexia have poor implicit memory for recently repeated stimuli, such as the train of standards in an oddball paradigm. Here, we examined how the neural representation of a standard emerges over repetitions, asking whether there is less sensitivity to repetition and/or less accrual of “standardness” over successive (...) repetitions in dyslexia. We recorded magnetoencephalography as adults with and without dyslexia were passively exposed to speech syllables in a roving-oddball design. We performed time-resolved multivariate decoding of the MEG sensor data to identify the neural signature of standard vs. deviant trials, independent of stimulus differences. This “multivariate mismatch” was equally robust and had a similar time course in the two groups. In both groups, standards generated by as few as two repetitions were distinct from deviants, indicating normal sensitivity to repetition in dyslexia. However, only in the control group did standards become increasingly different from deviants with repetition. These results suggest that many of the mechanisms that give rise to neural adaptation as well as mismatch responses are intact in dyslexia, with the possible exception of a putatively predictive mechanism that successively integrates recent sensory information into feedforward processing.

Hegel raises many real problems on the basis of the phenomenology of spirit: logico-ontological, gnoseological, and philosophico-historical problems. But in all spheres, levels, and forms of consciousness, Hegel investigates particularly the formation of the socially developed and historically oriented universal subject of thought, will, and action in the context of the forms of the manifest spirit, forms that in reality assume the status of being. It is precisely this investigation that constitutes the real problematic of Hegel's Phenomenology of Spirit.

The roots of much of Western medicine lie in the Christian monastic tradition and its commitment to nonstigmatizing compassionate care throughout the life cycle and to the ideal of empathic personal connection between physicians, patients, and the communities and relationships in which both of these are embedded. In the modern West, these Christianly informed aspects of medicine are increasingly being undercut as medical care becomes ever more specialized, technologized, and depersonalized. At the same time, there exist a variety of efforts (...) to counter these tendencies and to foster a practice of medicine that is more sensitive to the personal, relational, familial, and narrative dimensions of health, illness, and medical care. There are, in particular, considerable numbers of physicians, psychologists, and psychotherapists working at the intersections of biomedical and psychosocial care, of care for individuals and care for families, and of the body and the mind. Given the natural affinity that Christian bioethicists might be expected to have to communitarian, narrative, and family-oriented approaches to health care, it is thus remarkable that there appears to be no work of Christian bioethics that interacts in any discernible way with this psychotherapeutic literature concerning health, illness, families, and the mind-body interface. Instead, Christian bioethicists appear to endorse a narrowly reductionistic biomedical view of health and illness while either ignoring the psychosocial, integrative, and collaborative literature, or actively blaming and shaming those pastors or lay Christians who might have anything to do with psychotherapy or psychosocial care. This is unbecoming and unhelpful. In the fragmented, complex, and potentially dehumanizing world that is modern medical care, those who would think Christianly about the care of the sick cannot afford to despise psychology and psychosocial care. On the contrary, the church needs psychotherapy. In this article, I will thus consider, first, what the state of the conversation is where Christian bioethics and psychosocial and psychotherapeutic care are concerned. I will then turn to some of the principal landmarks in the professional literature concerning psychotherapeutic work with the sick, the disabled, the dying, and the bereaved, particularly as these are considered in contexts that include families and lay and professional caregivers. I will then identify a few opportunities for practical and theological reflection that present themselves in this literature, and will conclude with a few comments on the substance and relationship of salvation and health.
