The process of obtaining informed consent to participate in a clinical study presents many challenges for research conducted in a population of patients with schizophrenia. Morally valid, informed consent must include information sharing, decisional capacity, and capacity for voluntarism. This paper examines the unique features of schizophrenia that may threaten each of these elements of informed consent, and it proposes additional safeguards in the process of gaining informed consent from individuals with schizophrenia in order to maximise the decision-making potential of (...) this patient population.

The ontological model framework for an operational theory has generated much interest in recent years. The debate concerning reality of quantum states has been made more precise in this framework. With the introduction of generalized notion of contextuality in this framework, it has been shown that completely mixed state of a qubit is preparation contextual. Interestingly, this new idea of preparation contextuality has been used to demonstrate nonlocality of some \(\psi \) -epistemic models without any use of Bell’s inequality. In (...) particular, nonlocality of a non maximally \(\psi \) -epistemic model has been demonstrated from preparation contextuality of a maximally mixed qubit and Schrödinger’s steerability of the maximally entangled state of two qubits (Leifer and Maroney, Phys Rev Lett 110:120401, 2013). In this paper, we, show that any mixed state is preparation contextual. We, then, show that nonlocality of any bipartite pure entangled state, with Schmidt rank two, follows from preparation contextuality and steerability provided we impose certain condition on the epistemicity of the underlying ontological model. More interestingly, if the pure entangled state is of Schmidt rank greater than two, its nonlocality follows without any further condition on the epistemicity. Thus our result establishes a stronger connection between nonlocality and preparation contextuality by revealing nonlocality of any bipartite pure entangled states without any use of Bell-type inequality.

Our fascination with artificial intelligence (AI), robots and sentient machines has a long history, and references to such humanoids are present even in ancient myths and folklore. The advancements in digital and computational technology have turned this fascination into apprehension, with the machines often being depicted as a binary to the human. However, the recent domains of academic enquiry such as transhumanism and posthumanism have produced many a literature in the genre of science fiction (SF) that endeavours to alter this (...) antagonistic notion of AI. In his novel Klara and the Sun, Kazuo Ishiguro explores this notion of AI as a caring machine capable of nursing an ailing young girl back to health. Through this portrayal of AI as a sentient being capable of empathy and cognition, Ishiguro is attempting to usher in a new perception of AI: a posthuman perception that challenges the conventional notions of AI as a machine devoid of emotions. The novel further expands on the idea of self, soul and human consciousness and ponders on the question, what makes humans human, and if it is possible to imbibe these qualities onto an AI. Owing to the novelty of this notion, an unexplored avenue that deserves further exploration, this paper examines the plausibility of this new notion of AI through a careful exegesis of the novel. The paper also attempts to chart the impact of SF in society and culture. The study reveals a positive shift in perception towards AI, and there seems to be much scope for interdisciplinary and transdisciplinary research. (shrink)

This paper examines the perceived ethical values of Malaysian managers. It is based on the opinions of 15 hypothetical ethical/unethical business situations from the 81 managers who agreed to participate in the survey. The findings of this study showed that these Malaysian managers have high ethical values. However 53% of the respondents believed that the ethical standards of today are lower than that of 15 years ago. Apparently, this is related to the existence of many unethical business practices prevalent in (...) the modern business world. The behavior of one's immediate superior is the most important factor in influencing managers to commit unethical practices. The results also indicate only a slight variation among the managers in terms of perceived ethical values by virtue of job position, job specialization, type of business activity or the size of the business organization.

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative. explanation for visual multistability - that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the expression (...) of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non- visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non- sensory brain centers. Such direct intervention In the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

Recent data indicate that under a specific posthypnotic suggestion to circumvent reading, highly suggestible subjects successfully eliminated the Stroop interference effect. The present study examined whether an optical explanation could account for this finding. Using cyclopentolate hydrochloride eye drops to pharmacologically prevent visual accommodation in all subjects, behavioral Stroop data were collected from six highly hypnotizables and six less suggestibles using an optical setup that guaranteed either sharply focused or blurred vision. The highly suggestibles performed the Stroop task when naturally (...) vigilant, under posthypnotic suggestion not to read, and while visually blurred; the less suggestibles ran naturally vigilant, while looking away, and while visually blurred. Although visual accommodation was precluded for all subjects, posthypnotic suggestion effectively eliminated Stroop interference and was comparable to looking away in controls. These data strengthen the view that Stroop interference is neither robust nor inevitable and support the hypothesis that posthypnotic suggestion may exert a top-down influence on neural processing.

We present the opinion of some authors who believe there is no force between a stationary charge and a stationary resistive wire carrying a constant current. We show that this force is different from zero and present its main components: the force due to the charges induced in the wire by the test charge and a force proportional to the current in the resistive wire. We also discuss briefly a component of the force proportional to the square of the current (...) which should exist according to some models and another component due to the acceleration of the conduction electrons in a curved wire carrying a dc current (centripetal acceleration). Finally, we analyze experiments showing the existence of the electric field proportional to the current in resistive wires. (shrink)

The central focus of this paper is to motivate and explore the question, when is it permissible to endorse a psychologizing explanation of a sincere interlocutor? I am interested in the moral question of when (if ever) we may permissibly dismiss the sincere reasons given to us by others, and instead endorse an alternative explanation of their beliefs and actions. I argue that there is a significant risk of wronging the other person, and so we should only psychologize when we (...) are in a position to know that they are in bad faith. (shrink)

Traditionally the domain of scientists, the history of science became an independent field of inquiry only in the twentieth century and mostly after the Second World War. This process of emancipation was accompanied by a historiographical departure from previous, 'scientistic' practices, a transformation often attributed to influences from sociology, philosophy and history. Similarly, the liberal humanists who controlled the Cambridge History of Science Committee after 1945 emphasized that their contribution lay in the special expertise they, as trained historians, brought to (...) the venture. However, the scientists who had founded the Committee in the 1930s had already advocated a sophisticated contextual approach: innovation in the history of science thus clearly came also from within the ranks of scientists who practised in the field. Moreover, unlike their scientist predecessors on the Cambridge Committee, the liberal humanists supported a positivistic protocol that has since been criticized for its failure to properly contextualize early modern science. Lastly, while celebrating the rise of modern science as an international achievement, the liberal humanists also emphasized the peculiar Englishness of the phenomenon. In this respect, too, their outlook had much in common with the practices from which they attempted to distance their project. (shrink)

Huggins, AK When the debate about gay marriage really started to gain some momentum in Australia, probably a year or two before the last Labor Party Conference, I predicted amongst some of my gay friends that, as we got closer to a vote or other defining moments in this process, people and organisations would start 'crawling out of the woodwork' with distasteful, even despicable ways to demonise same-sex partnership and indeed gay people generally. I was right. I also mentioned to (...) my friends that in Sydney, Cardinal Pell and Archbishop Jensen would wait just before any parliament vote to politicise their pulpits by locking in the federal Liberal vote using their lap boy Tony Abbott to deny a conscience vote amongst his party colleagues. I was right again. I also said that any attempt by a State or Territory to pass their own gay marriage legislation would be countered by a Liberal Government in the High Court of Australia. I was right again. It is so difficult and regrettable to be right all the time!! (shrink)

In this paper, I argue for a conditional parity thesis: if we are agents with respect to our intentions, we are agents with respect to our beliefs. In the final section, I motivate a categorical version of the parity thesis: we are agents with respect to belief and intention. My aim in this paper is to show that there is no unique challenge facing epistemic agency that is not also facing agency with respect to intention. My thesis is ambitious on (...) two fronts. First, the parity thesis is a substantive thesis about the nature of belief and intention. I argue that there is a structural parity of belief and intention; the status of whether they are agential stands and falls together. Second, the parity thesis illuminates the nature of agency. It constrains what counts as a satisfactory account of agency: either we must accept agency of both belief and intention, or we must reject both. In the final section, I argue that we have prima facie reason to accept agency of belief and intention. Finally, I diagnose why there has been such resistance to epistemic agency. Epistemic agency is problematic, but its problems are problems with agency, not problems with epistemic agency. (shrink)

Sometimes it is practically beneficial to believe what is epistemically unwarranted. Philosophers have taken these cases to raise the question are there practical reasons for belief? Evidentialists argue that there cannot be any such reasons. Putative practical reasons for belief are not reasons for belief, but reasons to manage our beliefs in a particular way. Pragmatists are not convinced. They accept that some reasons for belief are practical. The debate, it is widely thought, is at an impasse. But this debate (...) fails to address what is puzzling and interesting about the cases. By focusing on reasons for belief, the debate completely overlooks the role of action in relation to belief. We should be talking about the reasons for actions that shape our beliefs, which I will call belief management. I argue for three related theses: the interesting cases that motivate the debate are about belief management; Evidentialism is irrelevant to belief management; agents have practical reasons to manage their beliefs with the aim of forming true beliefs. These reasons are categorical in nature and result in the tension of conflict cases. (shrink)

It has gradually become accepted among historians of ancient culture that the Greeks and Romans always, or nearly always, read aloud. They did not read to themselves, silently, save in rare and special cases. Either they were not able to read silently, or they felt no need to do so, or they did not enjoy doing it even when they were alone.
