This paper presents a computational model of the way humans inductively identify and aggregate concepts from the low-level stimuli they are exposed to. Based on the idea that humans tend to select the simplest structures, it implements a dynamic hierarchical chunking mechanism in which the decision whether to create a new chunk is based on an information-theoretic criterion, the Minimum Description Length (MDL) principle. We present theoretical justifications for this approach together with results of an experiment in which participants, exposed (...) to meaningless symbols, have been implicitly encouraged to create high-level concepts by grouping them. Results show that the designed model, called hereafter MDLChunker, makes precise quantitative predictions both on the kind of chunks created by the participants and also on the moment at which these creations occur. They suggest that the simplicity principle used to design MDLChunker is particularly efficient to model chunking mechanisms. The main interest of this model over existing ones is that it does not require any adjustable parameter. (shrink)

In this study, we examined students' attitudes toward cheating and whether they would report instances of cheating they witnessed. Data were collected from three educational institutions in Singapore. A total of 518 students participated in the study. Findings suggest that students perceived cheating behaviors involving exam-related situations to be serious, whereas plagiarism was rated as less serious. Cheating in the form of not contributing one's fair share in a group project was also perceived as a serious form of academic misconduct, (...) although a majority of the students admitted having engaged in such behavior. With regard to the prevalence of academic cheating, our findings suggest that students are morally ambivalent about academic cheating and are rather tolerant of dishonesty among their peers. On the issue of whether cheating behaviors should be reported, our findings revealed that a majority of students chose to take the expedient measure of ignoring the problem rather than to blow the whistle on their peers. Implications of our findings are discussed. (shrink)

Background: Moral distress has been described as a major problem for the nursing profession, and in recent years, a considerable amount of research has been undertaken to examine its causes and effects. However, few research projects have been performed that examined the moral distress of an entire nation’s nurses, as this particular study does. Aim/objective: The purpose of this study was to determine the frequency and intensity of moral distress experienced by registered nurses in New Zealand. Research design: The research (...) involved the use of a mainly quantitative approach supported by a slightly modified version of a survey based on the Moral Distress Scale–Revised. Participants and research context: In total, 1500 questionnaires were sent out at random to nurses working in general areas around New Zealand and 412 were returned, giving an adequate response rate of 27%. Ethical considerations: The project was evaluated and judged to be low risk and recorded as such on 22 February 2011 via the auspices of the Massey University Human Ethics Committee. Findings: Results indicate that the most frequent situations to cause nursing distress were (a) having to provide less than optimal care due to management decisions, (b) seeing patient care suffer due to lack of provider continuity and (c) working with others who are less than competent. The most distressing experiences resulted from (a) working with others who are unsafe or incompetent, (b) witnessing diminished care due to poor communication and (c) watching patients suffer due to a lack of provider continuity. Of the respondents, 48% reported having considered leaving their position due to the moral distress. Conclusion: The results imply that moral distress in nursing remains a highly significant and pertinent issue that requires greater consideration by health service managers, policymakers and nurse educators.

BackgroundCORE (Clarity and Openness in Reporting: E3-based) Reference (released May 2016 by the European Medical Writers Association [EMWA] and the American Medical Writers Association [AMWA]) is a complete and authoritative open-access user’s guide to support the authoring of clinical study reports (CSRs) for current industry-standard-design interventional studies. CORE Reference is a content guidance resource and is not a CSR Template.TransCelerate Biopharma Inc., an alliance of biopharmaceutical companies, released a CSR Template in November 2018 and recognised CORE Reference as one of (...) two principal sources used in its development.MethodsThe regulatory medical writing and statistical professionals who developed CORE Reference conducted a critical review of the TransCelerate CSR Template. We summarise our major findings and recommendations in this communication. We also re-examined and edited the Version 1 CORE Reference Terminology Table that we first published in 2016, and we present this as Version 2 in this communication.ResultsOur major critical review findings indicate that opportunities remain to refine the CSR Template structure and instructional text, enhance content clarity, add web links to referenced guidance documents, improve transparency to support the broad readership of CSRs, and develop supporting resources.The CORE Reference ‘Terminology Table’ Version 2 includes estimand as a defined term and an adaptation of the original ‘worked study example’ to incorporate the recently evolved concept of ‘estimands’.ConclusionsAs TransCelerate’s CSR Template represents an important milestone in authoring CSRs, we offer CSR authors advice and recommendations on its use, similarities, and differences with CORE Reference and advise them to consider shared interpretations between the two.RegistrationCORE Reference is registered with the EQUATOR Network. The TransCelerate CSR Template is not registered with any external organisation to the knowledge of the authors of this paper. (shrink)

Nanay (2015; 2016) revives manner or attitude accounts of aesthetic experience. While manner-based accounts are promising, Nanay's claim that certain kinds of aesthetic experiences require attention to be focused on one object, but distributed across many properties of that object, that 'aesthetic attention' is necessary for 'Proustian experience', is false. Attention to objects of aesthetic experience frequently involves attention to intra-objects, objects that are proper perceptual parts of the attended objects.

The present account, based on introspective comments, deals with motivation and hedonic tone as subjective factors which affect continuous work at high speeds. Actual introspective reports are given. The earlier papers in the series described the experimental procedure and presented objective data.

On May 24, 1995, the American Medical Association Council on Ethical and Judicial Affairs issued a rather controversial opinion that it is ethically permissible to use anencephalic infants as living organ donors. Approximately 1,000 to 2,000 infants are born each year in the United States with anencephaly, a congenital birth defect whereby the infant has no forebrain and cerebrum. Without higher brain functions, the infants can never experience consciousness, thoughts, emotions, or pain. Fewer than half survive more than a day, (...) and more than 90 percent die within one week. However, by the time brain death occurs in anencephalic infants, their organs are no longer suitable for donor purposes because they have deteriorated beyond use.In 1988, the AMA Council declared that it is ethical to use the infants as organ donors only after they have died. Now the Council has revised that opinion, and it proposes to allow removal of organs before death, as long as the parents consent and two doctors concur in the diagnosis of anencephaly. (shrink)
