A survey of the field of hypercomputation, including discussion of a variety of objections.

Joint attention has been extensively studied in the developmental literature because of overwhelming evidence that the ability to socially coordinate visual attention to an object is essential to healthy developmental outcomes, including language learning. The goal of this study was to understand the complex system of sensory-motor behaviors that may underlie the establishment of joint attention between parents and toddlers. In an experimental task, parents and toddlers played together with multiple toys. We objectively measured joint attention—and the sensory-motor behaviors that (...) underlie it—using a dual head-mounted eye-tracking system and frame-by-frame coding of manual actions. By tracking the momentary visual fixations and hand actions of each participant, we precisely determined just how often they fixated on the same object at the same time, the visual behaviors that preceded joint attention and manual behaviors that preceded and co-occurred with joint attention. We found that multiple sequential sensory-motor patterns lead to joint attention. In addition, there are developmental changes in this multi-pathway system evidenced as variations in strength among multiple routes. We propose that coordinated visual attention between parents and toddlers is primarily a sensory-motor behavior. Skill in achieving coordinated visual attention in social settings—like skills in other sensory-motor domains—emerges from multiple pathways to the same functional end. (shrink)

Accelerating Turing machines have attracted much attention in the last decade or so. They have been described as “the work-horse of hypercomputation” (Potgieter and Rosinger 2010: 853). But do they really compute beyond the “Turing limit”—e.g., compute the halting function? We argue that the answer depends on what you mean by an accelerating Turing machine, on what you mean by computation, and even on what you mean by a Turing machine. We show first that in the current literature the term (...) “accelerating Turing machine” is used to refer to two very different species of accelerating machine, which we call end-stage-in and end-stage-out machines, respectively. We argue that end-stage-in accelerating machines are not Turing machines at all. We then present two differing conceptions of computation, the internal and the external, and introduce the notion of an epistemic embedding of a computation. We argue that no accelerating Turing machine computes the halting function in the internal sense. Finally, we distinguish between two very different conceptions of the Turing machine, the purist conception and the realist conception; and we argue that Turing himself was no subscriber to the purist conception. We conclude that under the realist conception, but not under the purist conception, an accelerating Turing machine is able to compute the halting function in the external sense. We adopt a relatively informal approach throughout, since we take the key issues to be philosophical rather than mathematical. (shrink)

Accelerating Turing machines are Turing machines of a sort able to perform tasks that are commonly regarded as impossible for Turing machines. For example, they can determine whether or not the decimal representation of contains n consecutive 7s, for any n; solve the Turing-machine halting problem; and decide the predicate calculus. Are accelerating Turing machines, then, logically impossible devices? I argue that they are not. There are implications concerning the nature of effective procedures and the theoretical limits of computability. Contrary (...) to a recent paper by Bringsjord, Bello and Ferrucci, however, the concept of an accelerating Turing machine cannot be used to shove up Searle's Chinese room argument. (shrink)

Visual research methods like photography and digital storytelling are increasingly used in health and social sciences research as participatory approaches that benefit participants, researchers, and audiences. Visual methods involve a number of additional ethical considerations such as using identifiable content and ownership of creative outputs. As such, ethics committees should use different assessment frameworks to consider research protocols with visual methods. Here, we outline the limitations of ethics committees in assessing projects with a visual focus and highlight the sparse knowledge (...) on how researchers respond when they encounter ethical challenges in the practice of visual research. We propose a situated approach in relation to visual methodologies that encompasses a negotiated, flexible approach, given that ethical issues usually emerge in relation to the specific contexts of individual research projects. Drawing on available literature and two case studies, we identify and reflect on nuanced ethical implications in visual research, like tensions between aesthetics and research validity. The case studies highlight strategies developed in-situ to address the challenges two researchers encountered when using visual research methods, illustrating that some practice implications are not necessarily addressed using established ethical clearance procedures. A situated approach can ensure that visual research remains ethical, engaging, and rigorous. (shrink)

Turing’s analysis of computability has recently been challenged; it is claimed that it is circular to analyse the intuitive concept of numerical computability in terms of the Turing machine. This claim threatens the view, canonical in mathematics and cognitive science, that the concept of a systematic procedure or algorithm is to be explicated by reference to the capacities of Turing machines. We defend Turing’s analysis against the challenge of ‘deviant encodings’.Keywords: Systematic procedure; Turing machine; Church–Turing thesis; Deviant encoding; Acceptable encoding; (...) Turing’s analysis of computability; Turing’s Notational Thesis. (shrink)

The growing interest in Africa as well as concerns about negative deviant behaviors and ethnic structures necessitates examination of the effect of ethnic expectations on behavior of employees. In this study we leverage insight from ethnos oblige theory to propose that centralization of ethnic norms moderates the relationship between benevolence expectations and negative deviant behavior. Using a cross-sectional design and data from two countries as well as moderation and cross-cultural analytic techniques, we find support for three-way interactions where the relationship (...) between benevolence and negative deviant behavior is moderated by centralization and culture. We discuss the implications of the findings which support the dynamic perspective of management in Africa. (shrink)

Despite organizational ethical training programs, some employees still engage in unethical behavior. As such, organizational researchers have sought to examine why employees engage in unethical behavior and whether interventions can improve ethical misconduct. While some instruments measure moral development or ethical/unethical behaviors toward the organization, this study utilized a unique scale which evaluates perceptions of ethical misconduct (PEMS). Data from a large Midwestern university, a large Southeastern university, and Amazon’s Mechanical Turk were used in the analyses. An exploratory and confirmatory (...) factor analyses were used in the creation of the PEMS. To examine the validity of the scale, the PEMS was correlated to scales which measure Dark Triad traits and Counterproductive Work Behaviors (CWBs). Findings showed a significant positive correlation between the PEMS and both scales. The results also show that the PEMS mediates the relationship between psychopathy and CWBs. (shrink)

This research explores the contextual approach within Christian-Jewish religious education, addressing a notable gap in existing literature and offering fresh insights into the application of the Contextual Teaching and Learning (CTL) model within Christian contexts. Through a qualitative literature study employing a three-step methodology, including an in-depth analysis of Deuteronomy 11:19–20, this study reveals that this biblical text provides both educational guidance and theological significance, serving as a foundational support for the CTL model in Christian-Jewish religious education. The integration of (...) digital media into biblical sources holds promise for future research, while the central challenge lies in harmonising life experiences and empirical phenomena with biblical reflections to seamlessly integrate inquiry processes and pedagogical phases, with potential avenues for further exploration in scripture models endorsing CTL. This research provides valuable insights for educators, parents and policymakers in Indonesia and beyond, advancing educational research in contextualised teaching models within religious education.Contribution: This article demonstrates that the CTL model in the digital era has the potential to revolutionise religious education and profoundly impact learners, making it a significant scientific contribution in the context of Christian-Jewish religious education.

Workplace ostracism is a prevalent and painful experience. The majority of studies focus on negative outcomes of ostracism, with less work examining employees’ potential adaptive responses to it. Further, scholars have suggested that such responses depend on employee attributions, yet little research has taken an attributional perspective on workplace ostracism. Drawing on sociometer theory and attribution theory we develop and test a model that investigates why and under what circumstances ostracized employees engage in adaptive responses to ostracism. Specifically, we argue (...) that ostracized employees feel greater levels of shame and, in turn, are motivated to engage in greater ingratiation behavior toward their ostracizers. However, we predict that perceptions of ostracizers’ competence and warmth shape different attributional processes, which influence the degree to which the ostracized employee experience shame and, in turn, is motivated to engage in ingratiation behavior. Results of a three-wave, time-lagged survey support our prediction that shame mediates the relationship between coworker ostracism and ingratiation behavior. Moreover, results support our three-way interaction, such that coworkers who report higher levels of ostracism and who perceive their coworkers as more (vs. less) competent and more (vs. less) warm report higher shame, and, in turn, ingratiation behavior. Theoretical and practical implications, as well as avenues for future research, are discussed. (shrink)

Proposed educational outcomes for the health humanities in medical education range from empathy to visual thinking skills to social accountability. This lack of widely agreed-upon high-level curricular goals limits humanities educators’ ability to design purposeful curricula toward clear, common ends and threatens justifications for scarce curricular time. We propose a novel approach to the hoped-for outcomes of health humanities training in medical schools, which has the potential to encompass traditional health humanities knowledge, skills, and behaviors while also being concrete and (...) measurable: humanistic practice. Humanistic practice, adapted from the concept of ethical sensitivity, is an intentional process of applying humanities knowledge and skills to a clinical scenario by 1) noticing that the scenario requires humanities knowledge or skills, 2) informing one’s clinical and interpersonal strategy and behavior with humanities knowledge or skills, 3) reflecting on the effectiveness of the strategy and behavior, and 4) reorienting to develop new approaches for future practice. The construct of humanistic practice may help address some of the foundational problems in health humanities outcomes research since it transcends the traditional diverse content domains in the health humanities, can link patient and provider experiences, and may bridge the divide among the additive, curative, and intrinsic epistemic positions of humanities to medical education.

Many formerly incarcerated people have civil legal needs that can imperil their successful re-entry to society and, consequently, their health. We categorize these needs and assess their association with cardiovascular disease risk factors in a sample of recently released people. We find that having legal needs related to debt, public benefits, housing, or healthcare access is associated with psychosocial stress, but not uncontrolled high blood pressure or high cholesterol, in the first three months after release.

Theists believe that God is eternal, but they differ as to just what God's eternality means . The traditional, historic view of most Christian philosophers is that eternality means that God is timeless. He is ‘outside’ of time and not subject to any kind of temporal change. Indeed, God is the creator of time. Lets call this view divine timelessness.

Este artículo problematiza la forma en la que el feminismo ha interpretado al escepticismo como una amenaza para su proyecto epistemológico, ético y político, y plantea que, a pesar de dicha interpretación, el escepticismo es inherente a la filosofía feminista y un aliado útil para su proyecto. El problema ha estado en cómo el feminismo ha reducido su comprensión del escepticismo a una versión cartesiana extrema y ha pasado por alto otras corrientes de la tradición —como la de David Hume— (...) que podrían ser fructíferas para promover una actitud crítica y emancipatoria. Muestra así como una alianza entre una comprensión moderada del escepticismo y el feminismo puede brindar las herramientas necesarias para cuestionar formas de dominación patriarcal y poner en marcha investigaciones que combatan la opresión de género.

The eleventh-century Byzantine compiler Cedrenus includes a unique story in the midst of his otherwise traditional and hagiographic material on the emperor Constantine. Mentioning the outbreak of war between the Roman and Persian empires, he describes the cause of the breakdown of peace somewhat as follows. A certain Metrodorus, who was of Persian origin, went to visit the Brahmins in India to study philosophy and won the reputation of being a holy man through his asceticism. He also built water mills (...) and baths, unknown to the Indians till that time. Having acquired this reputation, he entered the temples and took away many precious stones and pearls. He also received gifts from the king of the Indians. On his return to Byzantium he gave them to the emperor Constantine as being gifts of his own. When Constantine expressed his astonishment, Metrodorus said he had sent other gifts by the land route but that they had been detained by the Persians. Constantine then wrote a strong protest to Sapor demanding the gifts but received no reply; thus the peace was broken. This remarkable conte, more appropriate to the Arabian Nights than to sober history, is generally supposed to be referred to in a passage in Ammianus. Towards the end of a long section commenting on the personality and achievements of Julian, Ammianus turns briefly to the question of the ultimate responsibility for the Persian War which ended so disastrously for Julian and the Roman Empire: et quoniam eum obtrectatoribus novos bellorum tumultus ad perniciem rei communis insimulant concitasse, sciant docente veritate perspicue, non Iulianum sed Constantinum ardores Parthicos succendisse, cum Metrodori mendaciis avidius acquiescit, ut dudum rettulimus plane.

Some objections to the idea that disputed territories should be auctioned.

The classical Reason is too often linked with the conquest of Nature and with modern scientific and technological world. But Bruno Pinchard shows that this kind of philosophizing is a source of freedom in the relation that is endeavored to be established between Faith and Rationality. The classical Reason is equidistant from the might of science and the dogmas of faith. This Reason is an actualization of pure thought. In this perspective, the author declares 12 propositions that would need to (...) be developed with historical proves to be fully justified. Meanwhile, these first steps have a systematic aim, like all the conceptual constructions of classical thought. The paper is concluded with a short “Coda” about the necessity of love to give strength to the reason to achieve ultimate goals of the latter. The translation is made according to the text which is a revised and updated version of the article: Pinchard B. Quelques principes de raison classique. L’Archicube, n° 24, juin 2018, pp. 156–164.
