The law of propositional logic that states the deducibility of either A or B from A is not valid for imperatives (Ross’s paradox, cf. [9]). The command (or request, advice, etc.) in (1a) does not imply (1a) (unless it is taken in its alternative-presenting sense), otherwise when told the former, I would be justified in burning the letter rather then posting it. (1) a. Post this letter! 6⇒ b. Po...

Using a longitudinal dataset which followed 2195 individuals employed in 3379 separate job placements over a four-year period, this paper explores movement between the employment supports, [Transitional (TE), Supported (SE), and Independent Employment (IE)], offered by clubhouses. Sixty-four percent of employed members held only one job (N=1395) and 36% held multiple jobs during the study (N=79...

Frequency hopping is a central method in wireless communication, offering improved resistance to adversarial interference and interception attempts, and easy non-coordinated control in dynamic environments. In this paper, we introduce a new model that supports a rigorous study of frequency hopping in adversarial settings. We then propose new frequency hopping protocols that allow a sender-recei...
