Difficulties with Applying a Strong Social Value Requirement to Clinical Research
Abstract:
In an insightful article published in this issue of the Hastings Center Report, Danielle Wenner criticizes what she describes as transactional approaches to the social value requirement in clinical research and defends a "basic structure approach." Transactional approaches understand social value obligations as arising from transactions (or relationships) between research subjects, investigators, sponsors, and other parties. The basic structure approach, by contrast, understands social value obligations as stemming from the demands of Rawlsian social justice. According to Wenner, "The primary justification for the social value requirement lies not in the ethics of free and fair transactions but rather in the goals of the clinical research enterprise and the nature of its impacts on society. The requirement is justified because it ensures that biomedical progress occurs in a manner constrained by considerations of justice." In this commentary, I will not critique the basic structure approach per se but will raise some concerns that arise when oversight committees, such as institutional reviews boards, attempt to apply it to proposed studies involving human subjects.

Titration Calculations: Strong Acid - Strong Base
A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH. The pH at different volumes of added base solution can be calculated as follows:
(a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then:
