Stem cell science is advancing at an unprecedented rate, with thousands of research papers being published every year and many clinical trials for a wide range of conditions underway as registered on ClinicalTrials.gov. This rapidly expanding and alluring field has brought with it ever more complex and multifaceted ethical issues, many of which require new guidelines, consent protocols and even change in legislation, since they do not fit comfortably in the existing bioethical regulations and protocols. Keeping up with the ethical (...) implications of stem cell research is daunting to the expert and non-expert. We review the various types of stem cells and then focus on multipotent and pluripotent cell types, since it is these cell types that bring with them the greatest research and therapeutic potential, while concurrently delivering novel ethical conundrums. Certain key considerations are currently lacking and what is needed is how to obtain permission from individuals who donate their biological material for both scientific inquiry and eventually, for their potential therapeutic utility.

It is shown that the jet mechanism derivable from the Lorentz deformation picture leads to a nearly constant average jet transverse momentum. It is pointed out that this is consistent with the high-energy experimental data. It is pointed out further that this result strengthens the physical basis for the minimal time-energy uncertainty combined covariantly with Heisenberg's space-momentum uncertainty relation.

This inclusive, cross-cultural study rethinks the nexus between engineering, development, and culture. It offers diverse commentary from a range of disciplinary perspectives on how the philosophies of today’s cultural triumvirate—American, European and Chinese—are shaped and given nuance by the cross-fertilization of engineering and development. Scholars from the humanities and social sciences as well as engineers themselves reflect on key questions that arise in this relational context, such as how international development work affects the professional views, identities, practice and ethics of (...) engineers. The first volume to offer a systematic and collaborative study that cuts across continental boundaries, the book delineates the kinds of skills and competences that tomorrow’s engineering success stories will require, and analyzes fascinating aspects of the interplay between engineering and philosophy, such as how traditionally Chinese ways of thinking can influence modern engineering practice in the world’s most populous country. China’s problematic mix of engineering woes and wonders, from the high-profile crash on its high-profile rail network to its ‘bird’s nest’ Olympic stadium, adds to the urgency for reform, while Europe’s Enlightenment-informed legal frameworks are contrasted with Chinese mechanisms in their governance of the field of nanotechnology, a crucial element of future technical evolution. Fascinating and compelling in equal measure, this volume addresses one of the topics at the leading edge of humanity’s quest to survive, and to thrive.​. (shrink)

Why do good people suffer? Does fate control the events that come our way? What is the difference between the reactions of men and women when a disaster occurs? Why did Jewish mothers kill their children in Ashkenazi countries? How did the Jews of Yemen tell about the deportation they were sentenced to? What explanation did the Hasidic Rebbe provide for what happened in the Holocaust? This is an unexpected journey through the Jewish bookcase - sometimes it is amusing, sometimes (...) horrifying, but always fascinating. A journey following one question and many answers, which expresses the human need to give meaning and meaning to the enigma of existence. (shrink)

Juvenal opens his eighth Satire with the question stemmata quid faciunt?, supplies an answer in line 20, nobilitas sola est atque unica virtus, and devotes the rest of the poem to exhorting his addressee to virtuous activity, both by negative exempla drawn from the degenerate nobility and by positive exempla drawn from the plebs, novi homines and the like. In lines 39–70 he addresses one particularly self-important noble and attempts to deflate his bombastic pride: in 56–67 he adduces an extended (...) illustration from the animal world, apparently such as was common in the schools of rhetoric.

Much has been written by many distinguished persons about the philosophical, religious and ethical considerations of doctors and their involvement with torture. What follows will not have the erudition or authority of the likes of St Augustine, Mahatma Gandi, Schopenhauer or Thomas Paine. It represents the views of a very ordinary person; a presumption defended by the submission that many very ordinary persons have been, and will be, instruments for effecting, assisting or condoning the physical or mental anguish of others. (...) As practitioners of medicine, we are particularly vulnerable, since our particular knowledge and our privileged position may be so easily abused--to the detriment of others. Those of us who practice clinical forensic medicine have even greater responsibility by virtue of our daily contact with the enforcement of law, criminal procedure, and the machinations of the judiciary. We are thus particularly well placed to monitor, encourage or discourage the occurrence of evil practices within the community. It is imperative, therefore, that the ordinary doctor should be cognisant of, and be party to, a code of conduct formulated by his peers and having reference to his obligations as a citizen, and doctor, and to his ability to manipulate human activity. Forensic physicians have further discretionary powers as arbiters in the marriage of the art and ethics of healing with the principles and practice of justice. (shrink)

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)
