Three experiments are reported in which the relationships between task format, item type, and strategy usage were investigated for a two-dimensional relational inference task. Contrary to past findings with linear syllogisms, it was found that parallel presentation (presenting problem statements simultaneously) did not result in any increased use of deduction rule processes compared with serial presentation (presenting problem statements individually). Instead, the results suggested that mental models were used by the majority of subjects, and that multiple models were more likely (...) to be constructed with parallel presentation. It is proposed that, in general, multiple model construction will be more frequent for deduction tasks where the cognitive load is relatively low. Hence, contrary to suggestions by Polk and Newell (1995), reasoning in this way appears to be prevalent and highly robust - where supported by task format - even where the use of this strategy is disadvantageous.

Many researchers have suggested that premise interpretation errors can account, at least in part, for errors on categorical syllogisms. However, although it is possible to show that people make such errors in simple inference tasks, the evidence for them is far less clear when actual syllogisms are administered. Part of the problem is due to the lack of clear predictions for the solutions that would be expected when using modified quantifiers, assuming that correct inferences are made from them. This paper (...) presents the expected solutions for Gricean, reversible, and reversible Gricean interpretations, and evaluates these using three datasets (two currently available, and one new). The evidence supported the adoption of reversible and reversible Gricean interpretations, but not Gricean interpretations on their own. These results suggest that the categorical syllogism task tends to induce different quantifier interpretations from those identified in simple inference tasks. (shrink)

This special issue arose from a joint conference of the History of Education Society, UK and the Australian and New Zealand History of Education Society, held in Malvern in Worcestershire, England in 2016 on the theme ‘sight, sound and text in the history of education’. The conference drew together media and educational historians, as well as archivists and museum professionals, to examine both methodological issues and a range of examples of sensory and textual histories. The three-day event, as well as (...) being enriching for its international character, proved that although much work has already been done in this area, there is so much more to consider and exploit when it comes to the study of the ‘new’ sonic and visual sources and their intertextual relationship with the documentary, as well as traditional understandings of ‘text’.

Since the publication of Edmund Gettier's challenge to the traditional epistemological doctrine of knowledge as justified true belief, Roberts and Wood claim that epistemologists lapsed into despondency and are currently open to novel approaches. One such approach is virtue epistemology, which can be divided into virtues as proper functions or epistemic character traits. The authors propose a notion of regulative epistemology, as opposed to a strict analytic epistemology, based on intellectual virtues that function not as rules or even as (...) skills but as habits of the heart. To that end, they divide the task of clarifying and expounding their notion in the book's two parts.In the first part, Roberts and Wood examine various components that constitute their notion of regulative epistemology. The first are the epistemic goods or goals that drive the epistemic process. What is needed, claim Roberts and Wood, is an enriched notion of these goods rather than the restricted notion of justified true belief. Epistemic agents are more than calculating devices in that ….

Philosophers have proposed many accounts of biological function. A coarse-grained distinction can be made between backward-looking views, which emphasise historical contributions to fitness, and forward-looking views, which emphasise the current contribution to fitness or role of a biological component within some larger system. These two views are often framed as being incompatible and conflicting with one another. The emerging field of synthetic biology, which involves applying engineering principles to the design and construction of biological systems, complicates things further by adding (...) intentional design as a source of function. In the current study we explored how biology experts and novices think about function in the context of single-celled, multi-celled, and synthetic organisms. We also explored the extent to which each group were function pluralists, and if they were function pluralists, which accounts of function tended to be endorsed together. The results showed a surprising degree of similarity between experts and novices in most contexts, although certain differences were apparent. Most surprisingly, we found evidence not only of function pluralism in both groups, but pluralism between backward-looking and forward-looking accounts. We discuss these findings in the context of the philosophical debate on function and consider the practical implications for public acceptance of synthetic biology. First, we argue that philosophers of biology should re-examine the purported incompatibility between accounts of function. Second, we argue that due to the introduction of an intentional aetiology in synthetic biology, there may be an inherent conflict between the views of experts and novices when thinking about synthetic biology.

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)

This paper predicts the probability of a profound world climate change that will affect the governance of the world's societies. Carbon dioxide levels in the earth's atmosphere may be doubled in sixty years, warming the earth's climate and altering drastically the patterns of food production, agriculture, forestry and consequently relations between societies.

The expanded use of genetic testing raises key ethical and policy questions about possible benefits and harms for those receiving disease‐risk information. As predictive testing for Huntington’s was initiated in a clinical setting, survey research posing hypothetical test scenarios suggested that the vast majority of at‐risk relatives wanted to know whether they carried a disease‐causing mutation. However, only a small minority ultimately availed themselves of this opportunity. Many at‐risk individuals concluded that a positive test result would be too psychologically overwhelming. (...) A substantial literature suggests that individuals are often more resilient than anticipated in coping with many different health‐related stresses. Much of my own work in the field has been through the Risk Evaluation & Education for Alzheimer’s Disease study (REVEAL), a series of randomized clinical trials assessing the impact of genetic susceptibility testing on asymptomatic individuals at risk for Alzheimer’s disease. Our experience in developing and implementing four successive, multisite trials provides some potentially useful lessons for the field. More people will be asking for their personal genetic information. Better understanding will help us decide when access is appropriate and how best to disclose results in a manner that supports adjustment to test findings and promotes use of genetic information to improve human health.

The devotion of a full article in the Paris Agreement to loss and damage was a major breakthrough for the world’s most vulnerable nations seeing to gain support for climate impacts beyond what can be adapted to. But how will loss and damage be paid for, and who will pay it? Will ethics be part of this decision? Here we ask what are the possible means of raising predictable and adequate levels of funding to address loss and damage? Utilizing a (...) framework developed by Marco Grasso, we argue that making the ethical connections between addressing climate impacts and finance mechanisms could significantly enhance their likelihood of being adopted. We briefly review insurance mechanisms and catastrophe bonds, and then move on to six “innovative finance” approaches to funding loss and damage. We utilize six criteria in assessing them: adequacy, predictability, technical feasibility, fairness, and indirect effects, and whether each has a clear link to loss and damage. Several mechanisms for gathering funds emerged as most promising. Three of the six financial mechanisms we reviewed to raise funding involved airline transport: clearly, there is a huge opportunity to tax this sector in one form or another, in recognition of airline emissions’ role in creating losses and damages in vulnerable nations from sea level rise, droughts, floods or hurricanes. Funding loss and damage response is a contentious issue that will get only more unwieldy if Parties’ conceptions of loss and damage are at odds: a common definition of loss and damage needs to be agreed upon under the UNFCCC. Most immediately, to meet any equity criteria, wealthy countries should do more to support the premiums of those who cannot afford insurance. (shrink)

The pessimistic arguments May challenges depend on an anti-Kantian philosophical assumption. That assumption is that what I call philosophical optimists about moral reason are also committed to empirical optimism, or what May calls “optimistic rationalism.” I place May's book in the literature by explaining how that assumption is resisted by Christine Korsgaard, one of May's examples of a contemporary Kantian.

With each novel infectious disease outbreak, there is scholarly attention to healthcare providers’ obligation to assume personal risk while they care for infected patients. While most agree that healthcare providers have a duty to assume some degree of risk, the extent of this obligation remains uncertain. Furthermore, these analyses rarely examine healthcare institutions’ obligations during these outbreaks. As a result, there is little practical guidance for healthcare institutions that are forced to weigh whether or when to exclude healthcare providers from (...) providing care or allow them to opt out from providing care to protect themselves. This article uses the COVID-19 pandemic to examine the concept of risk and the professional duties of both healthcare providers and healthcare institutions, and proposes a framework that can be used to make concrete institutional policy choices. This framework should be a useful tool for any hospital, clinic, or health agency that must make these choices during the current pandemic and beyond. (shrink)

Distance education has a long and complex history. It accounts for more than one-third of all higher education students in the world and, because of its very nature, has produced some of the top graduates worldwide who were unable to study fulltime and on-campus for various reasons. One of the most prestigious graduates of the DE system was the former state president of South Africa, the late Nelson Mandela. Online learning is a form of DE and fast becoming the preferred (...) method of instruction and delivery. Critiques of online learning, and of DE itself, will argue that, because of the separation of the teacher and the student, only academic skills can be taught and learnt using this medium. The so-called ‘softer skills’ – those that focus on the development of the person – are best taught in a face-to-face, traditional environment. This article focuses on a review of DE theories and models. A particular emphasis is placed on online learning theories, and how the teaching of formational learning skills can be successfully incorporated into this educational setting. The article draws from a range of studies that have been conducted, based on conceptual and empirical research evidence from various authors. Drawing from Garrison, Anderson and Archer’s Community of Inquiry framework for online education, it presents key elements that relate to the formational training of theology students. The article examines research that both supports and cautions against online learning for formative development. It concludes by suggesting a blended model of both face-to-face and online learning, where meaningful interactions between the learner and teacher take place, is desirable. The article highlights the important role that DE can play in developing the human component of education. (shrink)

The prophets of the Old Testament did make predictions, and biblical scholars are paying more attention to that fact. Now, serious theological reflection on what came of the predictions of the prophets is needed.

This study examines a moderated/mediated model of ethical leadership on follower job satisfaction and affective organizational commitment. We proposed that managers have the potential to be agents of virtue or vice within organizations. Specifically, through ethical leadership behavior we argued that managers can virtuously influence perceptions of ethical climate, which in turn will positively impact organizational members’ flourishing as measured by job satisfaction and affective commitment to the organization. We also hypothesized that perceptions of interactional justice would moderate the ethical (...) leadership-to-climate relationship. Our results indicate that ethical leadership has both a direct and indirect influence on follower job satisfaction and affective commitment. The indirect effect of ethical leadership involves shaping perceptions of ethical climate, which in turn, engender greater job satisfaction and affective organizational commitment. Furthermore, when interactional justice is perceived to be high, this strengthens the ethical leadership-to-climate relationship. (shrink)
