Although an individual speaker's productions obey locus equations, whether listeners' perceptions are based on them needs further exploration. Comparing the results from the perceptual experiments to predicted identifications, one sees qualitative similarities and some discrepancies. However, the variability of locus equations and individual consonant-vowel (CV) tokens across speakers seems problematic if listeners are using locus equations for perception.

Although the teaching of medical ethics and law in medical education is an old story that has been told many times in medical literature, recent studies show that medical students and physicians lack confidence when faced with ethical dilemmas and medico-legal issues. The adverse events rates and medical lawsuits are on the rise whereas many medical errors are mostly due to negligence or malpractices which are preventable. While it is true that many medical schools teach their students medical law and (...) ethics, there are wide variations in what is being taught because there is no universally agreed syllabus. Yet the knowledge of medical law and ethics is closely relevant to the medical profession and that failure in abiding the law may result in serious civil or even criminal consequences. While this paper does not propose to lay detailed analysis of the relevant areas of law or ethics, it proposes to cover some legal areas so as to highlight and bring to attention the need for a medical law and ethics course. This article also considers the problems faced and recommendation as to future directions to be taken with respect to teaching medical law and ethics. It concludes with a suggested course outline for the teaching of medical law and ethics. (shrink)

I. EXECUTIVE SUMMARY The MRCT Center Post-trial Responsibilities: Continued Access to an Investigational Medicine Framework outlines a case-based, principled, stakeholder approach to evaluate and guide ethical responsibilities to provide continued access to an investigational medicine at the conclusion of a patient’s participation in a clinical trial. The Post-trial Responsibilities (PTR) Framework includes this Guidance Document as well as the accompanying Toolkit. A 41-member international multi-stakeholder Workgroup convened by the Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard University (...) (MRCT Center) developed this Guidance and Toolkit. Project Motivation A number of international organizations have discussed the responsibilities stakeholders have to provide continued access to investigational medicines. The World Medical Association, for example, addressed post-trial access to medicines in Paragraph 34 of the Declaration of Helsinki (WMA, 2013): “In advance of a clinical trial, sponsors, researchers and host country governments should make provisions for post-trial access for all participants who still need an intervention identified as beneficial in the trial. This information must also be disclosed to participants during the informed consent process.” This paragraph and other international guidance documents converge on several consensus points: • Post-trial access (hereafter referred to as “continued access” in this Framework [for terminology clarification – see definitions]) is the responsibility of sponsors, researchers, and host country governments; • The plan for continued access should be determined before the trial begins, and before any individual gives their informed consent; • The protocol should delineate continued access plans; and • The plan should be transparent to potential participants and explained during the informed consent process. -/- However, there is no guidance on how to fulfill these responsibilities (i.e., linking specific responsibilities with specific stakeholders, conditions, and duration). To fill this gap, the MRCT Center convened a working group in September of 2014 to develop a framework to guide stakeholders with identified responsibilities. This resultant Framework sets forth applicable principles, approaches, recommendations and ethical rationales for PTR regarding continued access to investigational medicines for research participants.

This work presents results of improvement in the productivity of Arthrospira platensis in a company dedicated to its production. The six sigma methodology was applied in production processes that require the use of bioreactors. Starting from the analysis of the current state, aspects, physical and chemical variables that directly influence the productivity achieved were identified. Various culture media were tested and subsequently scaled for industrial production. In addition, the incorporation of carbon into the culture medium was controlled, optimizing the range (...) of potential hydrogen pH. The identified parameters were measured and six sigma methodology strategies were assigned. An improvement in productivity corresponding to 66% was verified with the same quality of final product.
