Efficient Runtime Detection and Toleration of Asymmetric Races

We introduce ToleRace, a runtime system that allows programs to detect and even tolerate asymmetric data races. Asymmetric races are race conditions where one thread correctly acquires and releases a lock for a shared variable while another thread improperly accesses the same variable. ToleRace provides approximate isolation in the critical sections of lock-based parallel programs by creating a local copy of each shared variable when entering a critical section, operating on the local copies, and propagating the appropriate copies upon leaving the critical section. We start by characterizing all possible interleavings that can cause races and precisely describe the effect of ToleRace in each case. Then, we study the theoretical aspects of an oracle that knows exactly what type of interleaving has occurred. Finally, we present software implementations of ToleRace and evaluate them on multithreaded applications from the SPLASH2 and PARSEC suites.

Perceived Deservingness and the Toleration of Human Rights Violations: The Problem and a Possible Solution

Despite general endorsement of universal human rights, people continue to tolerate specific human rights violations. I conducted a two-part study to investigate this issue. For Part I, I examined whether people tolerated torture (a human rights violation) based on the morality and deservingness of the target. Participants tolerated torture more when the target had committed a highly morally reprehensible transgression. This effect was mediated by the target’s perceived deservingness for harsh treatment, and held over and above participants’ abstract support for the right to humane treatment. For Part II, hypocrisy induction was used in an attempt to reduce participants’ toleration of the torture. Participants were assigned to either the hypocrisy induction or control condition. Unexpectedly, participants who tolerated the torture more in Part I reduced their toleration the most in the control condition, possibly because of consistency and floor effects. Limitations and implications of the findings are discussed.

Democracy, equality and toleration

In this paper I comment on a recent "letter" by Burleigh Wilkins addressed to nascent egalitarian democracies which offers advice on the achievement of religious toleration. I argue that while Wilkins’ advice is sound as far as it goes, it is nevertheless underdeveloped insofar as his letter fails to distinguish two competing conceptions of toleration – liberal-pluralist and republican-secularist – both of which are consistent with the advice he offers, but each of which yields very different policy recommendations (as can be seen by consideration of The United States v. Lee in America and, I’affaire du foulard in France). I argue that a democratic society of equals must be committed to liberal-pluralist rather than republican-secularist toleration
