Background To describe the preferences for disclosure of individual biomarker results among mothers participating in a longitudinal birth cohort. Methods We surveyed 343 mothers that participated in the Health Outcomes and Measures of the Environment Study about their biomarker disclosure preferences. Participants were told that the study was measuring pesticide metabolites in their biological specimens, and that the health effects of these low levels of exposure are unknown. Participants were asked whether they wanted to receive their results and their child's (...) results. In addition, they were asked about their preferred method (letter vs in person) and format (more complex vs less complex) for disclosure of results. Results Almost all of the study participants wanted to receive their individual results (340/343) as well as their child's results (342/343). However, preferences for receiving results differed by education level. Mothers with less than a college degree preferred in-person disclosure of results more often than mothers with some college education or a college degree (34.3% vs 17.4% vs 7.9%, p<0.001). Similarly, mothers with less than a college education preferred a less complex disclosure format than mothers with some college education or a college degree (59.7% vs 79.1% vs 86.3%, p<0.0001). Conclusion While almost all study participants preferred to receive results of their individual biomarker tests, level of education was a key factor in predicting preferences for disclosure of biomarker results. To ensure effective communication of this information, disclosure of biomarker results should be tailored to the education level of the study participants. (shrink)

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.

Many African scholars have expressed varied thoughts about the concept of a person, specifically about that which constitutes a person in African philosophy. These philosophers include Kwasi Wiredu, Kwame Gyekye and Segun Gbadegesin. What they have in common, though, is that their ideas on the concept of a person issue largely from the traditional philosophies of some West African peoples. Wiredu and Gyekye reflect on Akan conceptions while Gbadegesin carries out his discussions from the Yoruba cultural perspective. This paper examines (...) the thoughts of these prominent philosophers, with a particular focus on the constitution of the person and the nature of his or her destiny. (shrink)

Open peer commentary on the article “A Computational Constructivist Model as an Anticipatory Learning Mechanism for Coupled Agent–Environment Systems” by Filipo Studzinski Perotto. Upshot: Interaction-based models of cognition force anticipatory and constructivist models. The CALM model offers significant development of such models within a machine learning framework. It is suggested that moving to an entirely interactive-based model offers still further advantages.

Problem solving is an essential part of every scientific discipline. It has two components: (1) problem identification and formulation, and (2) the solution to the formulated problem. One can solve a problem on its own using ad hoc techniques or by following techniques that have produced efficient solutions to similar problems. This requires the understanding of various algorithm design techniques, how and when to use them to formulate solutions, and the context appropriate for each of them. Algorithms: Design Techniques and (...) Analysis advocates the study of algorithm design by presenting the most useful techniques and illustrating them with numerous examples -- emphasizing on design techniques in problem solving rather than algorithms topics like searching and sorting. Algorithmic analysis in connection with example algorithms are explored in detail. Each technique or strategy is covered in its own chapter through numerous examples of problems and their algorithms. Readers will be equipped with problem solving tools needed in advanced courses or research in science and engineering. (shrink)

If we reject τις, which appears only in derivative manuscripts, then the sentence is notable in the following ways. First, the position of τι—not that it separates ἕκαστος from ὑμν, but because we expect it, if present at all, to appear as πρός ὃ τι … and ἓαστός τι in itself is a conspicuously discordant juxtaposition—hence presumably the corruption to ἓαστός τις. Second, the sense: the sentence must surely mean not that each juryman has a criterion, but that each has (...) a different criterion, that he would like to see satisfied. (shrink)

Scientific chemical production on a commercial scale was evident in Britain in the early nineteenth century. One of the first palaeotechnic chemical industries was the manufacture of synthetic alkali. By 1823 a well-defined pattern of soda production had emerged. An understanding of this initial distribution is important as those areas associated with the early growth of the synthetic alkali industry showed a remarkable continuity of inorganic chemical production for the remainder of the century. The paper attempts to consider those factors (...) which contributed to this selective regional response, and in doing so, a number of interesting factors of location are revealed. (shrink)

As out-of-hospital emergencies become more commonplace, so does the call for a “doctor in the house”. New York City paediatrician Mitchell Rubin has responded to numerous such crises over the past 25 years. He explores reactions on all sides of this peculiar physician–victim relationship, his growing concerns and fears, and possible reasons why many doctors hesitate to act. His thoughts and experiences instigate the discussion about the need for a universal system of Good Samaritan physician respondersWhile flying to Italy last (...) spring, the pilot’s voice came over the loudspeaker: “Is there a doctor on board”? How many times have I heard this request in the last 25 years? A passenger had fainted. As I began caring for her, the pilot asked me, “Should we take the plane down?”. Surprised to be given this responsibility, I took my best guess and answered “no”. After a stressful landing, while I gave oxygen to the prostrate woman, we were met by an ambulance on the tarmac. The woman was appreciative and gracious, the pilot scarcely offered thanks, and I began my vacation exhausted.Having been trained as a paediatrician, I have responded to nearly two dozen “Good Samaritan” scenarios, where a person was injured or became critically sick in a public setting. Perhaps I have had more than my fair share, but I wonder if this is an important and mounting phenomenon. With America growing older and more and more people with serious, chronic illnesses remaining active in the community, we should not be surprised to see increasing numbers of out-of-hospital emergencies. And, as this becomes more commonplace, I become less and less certain of the role I—and other physicians like me—should have.When I was young, cocky and fearless, the call to meet an emergency was exciting. Shortly after training, an …. (shrink)
