Contrary to Michael Mandelbaum's claims, Russia tolerated Poland and the Czech Republic's NATO membership, and the Iran nuclear deal was a US strategic gain.
This Presidential Address offers elements for a systematic and cumulative study of destigmatization, or the process by which low-status groups gain recognition and worth. Contemporary sociologists ...tend to focus on inequality in the distribution of resources, such as occupations, education, and wealth. Complementing this research, this address draws attention to “recognition gaps,” defined as disparities in worth and cultural membership between groups in a society. I first describe how neoliberalism promotes growing recognition gaps. Then, drawing on research on stigmatized groups across several societies, I analyze how experiences of stigma and destigmatization are enabled and constrained by various contextual factors and actors, including institutions, cultural repertoires, knowledge workers, and social movement activists. I conclude by proposing a research agenda for the sociology of recognition and destigmatization, and by sketching how social scientists, policymakers, organizations, and citizens can contribute to the reduction of recognition gaps.
A novel set-membership control strategy is investigated for a class of discrete time-varying systems with unknown-but-bounded noises. Different from some existing set-membership estimation based ...control methods, the proposed control strategy is designed by using state estimation sets instead of some specific estimation points. The controlled performance requirement is modelled as a new set-membership performance constraint which ensures that the controlled output meets the requirement at any time instant. First, the set-membership filtering method is used for obtaining the ellipsoidal state estimation set. Second, a set-membership controller is constructed by utilising the state estimation which is arbitrarily chosen from the corresponding estimation set. Accordingly, sufficient conditions are derived such that the controlled system is asymptotically stable and satisfies the proposed performance constraint in the presence of unknown-but-bounded noises at each time instant. Then, a constructive computational algorithm is provided to describe the proposed control strategy. Finally, illustrative simulation examples are presented to demonstrate the effectiveness of the proposed method.
