The present paper analyzes the self‐generated explanations (from talk‐aloud protocols) that “Good” and “Poor” students produce while studying worked‐out examples of mechanics problems, and their subsequent reliance on examples during problem solving. We find that “Good” students learn with understanding: They generate many explanations which refine and expand the conditions for the action parts of the example solutions, and relate these actions to principles in the text. These self‐explanations are guided by accurate monitoring of their own understanding and misunderstanding. Such (...) learning results in example‐independent knowledge and in a better understanding of the principles presented in the text. “Poor” students do not generate sufficient self‐explanations, monitor their learning inaccurately, and subsequently rely heavily on examples. We then discuss the role of self‐explanations in facilitating problem solving, as well as the adequacy of current AI models of explanation‐based learning to account for these psychological findings.

We tested the hypothesis that perception of an alternative image in ambiguous figures would be manifest as high-frequency (gamma) components that become synchronized over multiple scalp sites as a ''cognitive binding'' process occurs. For 171 combinations of data from 19 electrodes, obtained from 17 subjects and 10 replicate stimuli, we calculated the difference in correlation between the response to first seeing an ambiguous figure and when the alternative percept for that figure became consciously realized (cognitively bound). Numerous statistically significant correlation (...) differences occurred in all frequency bands tested with ambiguous-figure stimulation, but not in two kinds of control data (a reaction-time test to sound stimuli and a no-task, mind-wandering test). Statistically significant correlation changes were widespread, involving frontal, parietal, central, and occipital regions of both hemispheres. Correlation changes were evident at each of five frequency bands, ranging up to 62.5 Hz. Most of the statistically significant correlation changes were not between adjacent sites but between sites relatively distant, both ipsilateral and contralateral. Typically, these correlation changes occurred in more than one frequency band. These results suggest that cognitive binding is a distinct mental state that is reliably induced by ambiguous-figure perception tasks. Coherent oscillations at multiple frequencies may reflect the mechanism by which such binding occurs. Moreover, different coherent frequencies may mediate different components of the total cognitive-binding process. (shrink)

The Database on Ethics Related Legislation and Guidelines was launched in March 2007 as the fourth database of the UNESCO Global Ethics Observatory system of databases in ethics of science and technology. The database offers a collection of legal instruments searchable by region, country, bioethical themes, legal categories and applicability to specific articles of the UNESCO Universal Declaration on Bioethics and Human Rights and International Declaration on Human Genetic Data. This paper discusses the background and rationale for the database and (...) its role as a consultative and comparative resource hub for the study of ethics related legal instruments across the world, with the purpose of informing and inspiring relevant stakeholders on the implementation of the principles contained within the UNESCO declarations on bioethics.

Objectives The objective of this research was to develop ethics accreditation standards for hospitals. Research design Our research methods included a literature review, an expert focus group, the Delphi technique and a hospital survey. The entire process was separated into two stages: (1) the development of a draft of hospital ethics accreditation standards; and (2) conducting a nationwide hospital survey of the proposed standards. Results This study produced a tentative draft of hospital ethics accreditation standards comprised of six chapters and (...) 62 standards based on the expert focus group and Delphi technique. The six chapters are: Medical ethics policies, regulations and leadership; The establishment and operation of a medical ethics committee; The establishment and operation of research-related ethics committees; Medical ethics education; Organisational ethical climate; and Respect for patients' rights and establishment of good hospital-patient relationships. The hospital survey indicated that the concept of an organisational ethical climate was new to most hospital managers, most hospitals disliked the idea of having a separate hospital ethics accreditation system, and small hospitals were concerned about their ability to comply with all of the standards. Conclusions Regardless of whether hospital ethics accreditation can be a stand-alone accreditation or just part of existing hospital accreditation programmes, we hope this draft can serve as a good reference for future endeavours by hospital accreditation authorities.

In lieu of an abstract, here is a brief excerpt of the content:Hermeneutics, Neuroscience and PsychiatryMichael T. H. Wong, MBBS, MD, MA, MDiv, PhD, FRCPsych, FRANZCP, FHKAM (bio)Hermeneutic practice in mental health has been a theme in Philosophy, Psychiatry, & Psychology (PPP) since its very beginnings. In this essay I argue that hermeneutics, the theory and practice of interpretation, promotes therapeutic interaction between mental health professionals, patients and their family.Why does this patient present in such a way at this particular (...) point in time? The distressing symptoms are there. The changes in behavior are obvious. Impairments of functions are hurting. A mental illness clearly runs in the family. There were early losses of loved ones, physical abuse at home, bullying by peers and self-medication with drugs and alcohol. Three in four adults with a mental illness first experienced that before they turned 24. The brain goes through major reorganization during adolescence and early adulthood. If synaptic pruning went wrong, psychoses emerged. When stresses activated the hypothalamic–pituitary–adrenal axis the elevated cortisol level impacted the size and function of the hippocampus and amygdala in the genetically vulnerable; anxiety, depression, bipolar, and personality disorders developed. The patient needs a voice/language to describe all these experiences and events and the psychiatrist needs a discourse to make sense of them.Eisenberg laments the swings between "brainlessness" and "mindlessness" in psychiatry. Engel argues for a "biopsychosocial" discourse. The major challenge for psychiatry is how to organize clinical information of different nature (categories, dimensions, narratives; i.e., objective vs. subjective, personal vs. interpersonal) into a coherent and comprehensible account for us all. Mental illnesses are not only neuropsychiatric spectrum disorders but also dysfunctions of social relationship and environmental/ecological adaptation. Psychiatry as a clinical neuroscience per se lacks the semantics to address the rich interactions between the physical, psychological, social, cultural, and spiritual in the illness experience of our patients. Explanation in the diagnostic formulation (objective scientific discourse on cause and effect) and understanding in the patient narrative (subjective ordinary everyday discourse on significance and meaning) are irreducible to each other (Wong, 2018). They instead interact with one another to achieve an integrative formulation, not through merging different discourses into a single assertion/monologue but via the dialectic/dialogue of "explaining more in order to understand better," as Ricoeur puts it, and between "the whole and the parts," as Schleiermacher highlights.This "therapeutic hermeneutic circle" of "explanation vs understanding" and "the whole vs the parts" includes symptoms behavior function and life events. It correlates between bio-psychosociocultural-spiritual dimensions/perspectives and does not reduce them to any particular/single [End Page 13] stance. The whole integrates the parts and the parts enrich the whole. It explains but does not explain away. It understands through an articulation of meaning and significance. This discourse is a multilayered (bio-psycho-social-cultural-spiritual) personal narrative that formulates diagnosis and care in a correlative (linking different voices/discourses) and non-reductive (no particular voice/discourse is prejudiced against) manner that is comprehensible to us all (Wong, 2021).PPP will be an excellent forum for discussing clinical hermeneutics in the future. In this digital era of social media and virtual reality, hermeneutics has the never-ending task to tackle the unprecedented challenges to meaning illness and health posed by polarizing discourses.Michael T.

Public health emergencies, such as the Covid-19 pandemic, put great pressure on healthcare workers (HCW) across the world, possibly increasing the risk of experiencing ethically challenging situations (ECS). Whereas experiencing ECS as a HCW in such situations is likely unavoidable, mitigation of their adverse effects (e.g., moral distress) is necessary to reduce the risk of long-term negative consequences. One possible route of mitigation of these effects is via work environmental factors. The current study aimed to examine: [1] risk factors associated (...) with ECS among HCW [2], intensity of moral distress associated with ECS across various occupational factors (i.e., profession, degree of exposure to patients with Covid-19), and [3] the impact of work environmental factors on this association, in a sample of HCW during the pandemic. We employed multiple logistic and linear regression to self-report data from 977 HCWs at four Norwegian hospitals responding to a survey at the fourth wave of the pandemic. About half of HCW in this study had experienced ECS during the pandemic, and levels of moral distress associated with such were higher than in previous studies using similar assessment methods. Younger age, female sex, geographical work area (mid-north of Norway), and profession (nurse) were all associated with higher odds (range of OR: 1.30–2.59) of experiencing ECS, as were direct contact with patients with Covid-19. Among those participants who reported that they had experienced ECS during the pandemic, moral distress levels when recalling those situations were moderate (Mean 5.7 on a 0–10 scale). Men reported somewhat lower intensity of moral distress (partial eta squared; ηp2 = 0.02). Reporting a manageable workload (ηp2 = 0.02), and greater opportunity to work according to best practice (ηp2 = 0.02), were associated with lower levels of moral distress. Our findings suggest that moral distress could potentially be mitigated on an organizational level, particularly by focusing on ensuring a manageable workload, and an ability to work according to best practice. To build sustainable healthcare systems robust enough to withstand future public health emergencies, healthcare organizations should implement measures to facilitate these aspects of HCWs’ work environment.
