The Disability Dilemma: A Skeptical Bench & Bar

Policing Bench and Bar: Ethical Imperatives

Effects of the bench shirt on sagittal bar path.

Powerlifting, like many sports, uses specialized equipment to enhance performance and decrease the chance of injury. The purpose of this exploratory study was to determine whether wearing a bench press shirt would alter the natural mechanics of the bench press, causing a more efficient lift when pressing the same weight as without the bench shirt. Participants (n = 5) completed 2 series of 1-re...

Fatigue effects on bar kinematics during the bench press.

The bench press is one of the most popular weight training exercises. Although most training regimens incorporate multiple repetition sets, there are few data describing how the kinematics of a lift change during a set to failure. To examine these changes, recreational lifters (10 men and 8 women) were recruited. The maximum weight each subject could bench press (1RM) was determined. Subjects t...

A skeptical biochemist

Social history, especially of bioethics, is bound to be problematic unless it is predicated upon a clear analysis of the substantive ethical issues. At issue in the 1960s was whether research standards should be subjective guidelines, enforced by the researcher's conscience, externally enforced objective rules, or intersubjective standards enforced by review committees (IRBs). In a series of pa...

What Is a Skeptical Proof?

We investigate the task of skeptically reasoning in extensionbased, nonmonotonic logics by concentrating on general argumentation theories. The restricted applicability of Dung’s notion of skeptical provability in his well-known argumentation framework is illustrated, and a new approach based on the notion of a claim associated with each argument is proposed. We provide a formal definition of a...
