A theoretical framework for the reinforcement learning of aesthetic biases was recently proposed based on brain circuitries revealed by neuroimaging. A model grounded on that framework accounted for interesting features of human aesthetic biases. These features included individuality, cultural predispositions, stochastic dynamics of learning and aesthetic biases, and the peak-shift effect. However, despite the success in explaining these features, a potential weakness was the linearity of the value function used to predict reward. This linearity meant that the learning process employed (...) a value function that assumed a linear relationship between reward and sensory stimuli. Linearity is common in reinforcement learning in neuroscience. However, linearity can be problematic because neural mechanisms and the dependence of reward on sensory stimuli were typically nonlinear. Here, we analyze the learning performance with models including optimal nonlinear value functions. We also compare updating the free parameters of the value functions with the delta rule, which neuroscience models use frequently, vs. updating with a new Phi rule that considers the structure of the nonlinearities. Our computer simulations showed that optimal nonlinear value functions resulted in improvements of learning errors when the reward models were nonlinear. Similarly, the new Phi rule led to improvements in these errors. These improvements were accompanied by the straightening of the trajectories of the vector of free parameters in its phase space. This straightening meant that the process became more efficient in learning the prediction of reward. Surprisingly, however, this improved efficiency had a complex relationship with the rate of learning. Finally, the stochasticity arising from the probabilistic sampling of sensory stimuli, rewards, and motivations helped the learning process narrow the range of free parameters to nearly optimal outcomes. Therefore, we suggest that value functions and update rules optimized for social and ecological constraints are ideal for learning aesthetic biases. (shrink)

How do we come to like the things that we do? Each one of us starts from a relatively similar state at birth, yet we end up with vastly different sets of aesthetic preferences. These preferences go on to define us both as individuals and as members of our cultures. Therefore, it is important to understand how aesthetic preferences form over our lifetimes. This poses a challenging problem: to understand this process, one must account for the many factors at play (...) in the formation of aesthetic values and how these factors influence each other over time. A general framework based on basic neuroscientific principles that can also account for this process is needed. Here, we present such a framework and illustrate it through a model that accounts for the trajectories of aesthetic values over time. Our framework is inspired by meta-analytic data of neuroimaging studies of aesthetic appraisal. This framework incorporates effects of sensory inputs, rewards, and motivational states. Crucially, each one of these effects is probabilistic. We model their interactions under a reinforcement-learning circuitry. Simulations of this model and mathematical analysis of the framework lead to three main findings. First, different people may develop distinct weighing of aesthetic variables because of individual variability in motivation. Second, individuals from different cultures and environments may develop different aesthetic values because of unique sensory inputs and social rewards. Third, because learning is stochastic stemming from probabilistic sensory inputs, motivations, and rewards, aesthetic values vary in time. These three theoretical findings account for different lines of empirical research. Through our study, we hope to provide a general and unifying framework for understanding the various aspects involved in the formation of aesthetic values over time. (shrink)

I was a delicate child, and to my great embarrassment I was excused from gymnastics as a teenager owing to an illness whose identity is still mystery, at least to me. That is when I acquired my world-weariness, a permanent and invincible lethargy that was to get worse with the passing years. Tiredness as a natural state has for many years been a recurring theme, when I'm complaining about life in letters and conversation. My friends consider it a bad habit (...) of mine, almost an attempt to attract attention, and they don't take me seriously. “I'm increasingly falling apart”, I recently told an old friend. He replied with a slightly mocking air: “You've been telling me that for twenty years”. But the truth is - and it is difficult to explain this to anyone younger - that the descent into the void is long, much longer than I would have ever imagined, and slow, so slow as to appear almost imperceptible (although not to me). The descent is continuous and, what is worse, irreversible: you descend one step at a time, but having put your foot on the lower step, you know that you will never return to the higher one. I have no idea how many more downward steps are to follow. I can only be sure that their number is steadily decreasing. (shrink)

It is a commonplace to observe that the idea of natural law has polarised contemporary legal philosophy; jurists who are not for it are against it. More than once in its long history, going back to the very origins of philosophy in Western Europe, the natural law has been in eclipse, but it has invariably survived and, as one of its severest critics, Bergbohm, was forced to admit, the funeral orations pronounced over it have proved to be premature. In the (...) nineteenth century Benthamite utilitarianism, Comtist positivism and the historical jurisprudence of von Savigny made a lean period for the natural law. But the twentieth century saw the revival. In 1910 appeared J. Charmont’s Renaissance du droit nature!; the 1920’s saw the first of Jacques Leclercq’s Lefons de droit nature!; in 1930 Charles Grove Haines studied the natural law in contemporary jurisprudence in The Revival of Natural Law Concepts; and in 1936 appeared the first edition of Heinrich Rommen’s Die ewige Wiederkehr des Naturrechts. The movement towards the natural law, of which these books are only some of the indications, was greatly accelerated when men discovered the need for a defence against the excesses of totalitarian power; and, after the war, the Nuremberg trials proceeded upon what amounted to a basis of natural law. Not all, of course, are prepared to admit that the natural law is the only alternative to positivism and relativism in legal philosophy or even that the concept possesses vitality: the contemporary interest in the natural law, Norberto Bobbio has observed rather sourly, is rather like the interest of anatomists in a cadaver.

This study described the relationships between academic class and student moral sensitivity and reasoning and between curriculum design components for ethics education and student moral sensitivity and reasoning. The data were collected from freshman (n = 506) and senior students (n = 440) in eight baccalaureate nursing programs in South Korea by survey; the survey consisted of the Korean Moral Sensitivity Questionnaire and the Korean Defining Issues Test. The results showed that moral sensitivity scores in patient-oriented care and conflict were (...) higher in senior students than in freshman students. Furthermore, more hours of ethics content were associated with higher principled thinking scores of senior students. Nursing education in South Korea may have an impact on developing student moral sensitivity. Planned ethics content in nursing curricula is necessary to improve moral sensitivity and moral reasoning of students. (shrink)

This text explores how human beings construe experience: experience as a resource, as a potential for understanding, representing and acting on reality.

Purpose– The purpose of this paper is to introduce the term Slow Tech as a way of describing information and communication technology that is good, clean and fair. These are technologies that are human centred, environmentally sustainable and socially desirable.Design/methodology/approach– The paper's approach is based on a qualitative discourse that justifies the introduction of Slow Tech as a new design paradigm.Findings– The limits of the human body, and the need to take into account human wellbeing, the limits of the planet (...) and stakeholders' interests in decision making, all suggest the need for a new paradigm, Slow Tech, in the design of ICT and ICT systems. Three scenarios are described as case studies.Practical implications– In order to prepare the next generation of researchers and computer professionals, many different actions need to be taken. Universities and colleges need to redesign education programmes for computer scientists and engineers by introducing subjects related to the social and ethical implications of computing, and computer professionals' associations need to introduce a code of ethics or ethical analysis into their members' career development. As a result, future computer professionals who are familiar with the Slow Tech approach will be able to collaborate much more easily across the kind of cross disciplinary teams suited to design human centred, sustainable and desirable technologies.Social implications– Rather than simply focusing on the role of computer professionals, all members of society are called to play a new role in the design of future ICT scenarios. Starting a societal dialogue that involves computer professionals, users, researchers, designers, ICT industrialists, and policy makers is very much needed.Originality/value– The value of this paper is in its call for reflection followed by action. Based on an holistic approach to the design of new ICT systems, the paper advocates a new starting point for systems design: it should be based on a long-term view of the desirability and social importance of technologies, their environmental impact and sustainability, and the fairness and equity of the conditions of workers involved in the computing manufacturing processes.

Based on the notion of bad faith, the article seeks to lay the foundations for a diagnosis of contemporaneity, having as an index, on the one hand, the lack of human determination and, on the other, the effectiveness of the world.

This article discusses the contribution to evolutionary theory of Leonard Darwin, the eighth child of Charles Darwin. By analysing the correspondence Leonard Darwin maintained with Ronald Aylmer Fisher in conjunction with an assessment of his books and other written works between the 1910s and 1930s, this article argues for a more prominent role played by him than the previously recognised in the literature as an informal mentor of Fisher. The paper discusses Leonard’s efforts to amalgamate Mendelism with both Eugenics and (...) Darwinism in order for the first to base their policies on new scientific developments and to help the second in finding a target for natural selection. Without a formal qualification in biological sciences and as such mistrusted by some “formal” scientists, Leonard Darwin engaged with key themes of Darwinism such as mimicry, the role of mutations on speciation and the process of genetic variability, arriving at important conclusions concerning the usefulness of Mendelian genetics for his father’s theory.

The text is part of the investigative concerns from the authors with regard to the dialogue between literature and science teaching. It starts from several theoretical approaches around the general didactics, university or superior didactics, science’s didactics and for last, literature’s didactics. This is largely due to our search which is focused in articulate the university didactics with science and literature’s didactics, meanwhile, we pretend to answer to the questions ¿How are the specific didactics of science and literature going to (...) contribute to the university didactics and how is the last one going to contribute to these specific didactics? ¿Is it the dialogue between science and literature possible? The paper has been made in middle education, in Educative Institution José Miguel de Restrepo y Puerta, from Copacabana and also in university education, in the academic unities of Dietetics and Nutrition School, Agricultural Sciences and Medicine, from the University of Antioquia. Finally, the partial results indicate: i) the necessity of general Didactics as a discipline focused on teaching and learning processes to ask itself for its internal problems and establish relations with specific didactics.

Mexico faces a crisis of national sovereignty and independence as it struggles to establish a democracy amidst integration into the world market system and internal demands for social justice. U.S. involvement in Mexican affairs, providing military training and equipment for government troops, contributes to a state-sponsored war against civilians, namely indigenous groups and the middle and lower classes devastated by NAFTA. While resistance movements in Chiapas respond to capitalist practices and repression, Valdez argues the Mexican government minimizes them to displace (...) its indigenousgroups and facilitate their silent annihilation. U.S. policy, the Mexican state, indigenous issues, and free trade are interconnected with Mexico’s larger society. (shrink)

Purpose– The purpose of this paper is to examine how Slow Tech can support the celebration of the 20-year series of ETHICOMP conferences, with its ethical and societal focus, building on earlier descriptions of Slow Tech. The paper takes Slow Tech’s ideas a step further to explore how a roadmap and concrete checklist of activities can be developed.Design/methodology/approach– The paper is a thought leadership or conceptual piece. Its approach is based on a normative, qualitative discourse. It, nevertheless, indicates a shift (...) towards concrete actions.Findings– Extracting from a brief historical overview, the paper lays out the means of building a Slow Tech roadmap and a Slow Tech checklist of actions. It also investigates a number of the challenges that might face Slow Tech in the future.Research limitations/implications– The paper has implications for stakeholder fields as far-ranging as corporations, computing professional associations, universities and research institutions and end-users.Originality/value– As with other investigations of Slow Tech, the value of this paper is in its call for reflection followed by action. It provides a useful complement and counterbalance to an earlier paper by the same authors: “Slow Tech: a quest for good, clean and fair ICT” published inJournal of Information, Communication and Ethics in Society.

Purpose– This paper aims to provide an overview of clean information and communication technology, including a brief review of recent developments in the field and a lengthy set of possible reading matter. The need to rethink the impact of ICTs on people’s lives and the survival of the planet is beginning to be addressed by a Slow Tech approach. Among Slow Tech’s main questions are these two: Is ICT sustainable in the long term? What should be done by computer ethics (...) scholars, computer professionals, policy makers and society in general to ensure that clean ICT can be produced, used and appropriately disposed of?Design/methodology/approach– The paper is based on a comprehensive review of clean tech-related literature and an investigation of progress made in the clean tech field.Findings– This opening paper of aJournal of Information, Communication and Ethics in Societyspecial session aims to provide an overview of clean ICT, including a brief review of recent developments in the field and a lengthy set of possible reading matter. As a result, it is anticipated that Slow Tech – and in this case, its second component of clean ICT – can provide a compass to steer research, development and the use and reuse of environmentally friendly, sustainable ICT.Originality/value– This conceptual paper emphasises that, until only recently, no one questioned the potential long-term sustainability of ICT. This issue is, however, now very much a matter that is on the research and teaching, and action, agenda. (shrink)

In recent literature, panpsychism has been defended by appeal to two main arguments: first, an argument from philosophy of mind, according to which panpsychism is the only view which successfully integrates consciousness into the physical world (Strawson 2006; Chalmers 2013); second, an argument from categorical properties, according to which panpsychism offers the only positive account of the categorical or intrinsic nature of physical reality (Seager 2006; Adams 2007; Alter and Nagasawa 2012). Historically, however, panpsychism has also been defended by appeal (...) to a third argument based on considerations about the nature and observability of causation. This argument has not been much discussed in recent times. Here is a concise version from William James: "… the concrete perceptual flux, taken just as it comes, offers in our own activity-situations perfectly comprehensible instances of causal agency … If we took these experiences as the type of what actual causation is, we should have to ascribe to cases of causation outside of our life, to physical cases also, an inwardly experiential nature. In other words, we should have to espouse a so-called “pan-psychic” philosophy" (James 1911: 218). James here suggests that we have direct experience of causation in our own agency. He thereby directly contradicts David Hume, who famously denied that we have any experience of causation. James goes on to claim that if this experience is representative of causation in general, it follows that all causation is mental, and that panpsychism is true. This kind of argument for panpsychism can be called the argument from (experience of) causation. This chapter offers, first, a history of this argument and arguments closely related to it, and second, an analysis of the argument – is it valid, are its premises in any way defensible, and how does it relate to the other, more popular arguments for panpsychism from philosophy of mind and categorical properties?
