Inverse obstacle problems

Abstract: In this review, we describe the main results on the uniqueness and stability of penetrable or impenetrable obstacles from various boundary data. We present basic ideas of proofs in the case of single and many boundary measurements. We discuss some methods of reconstruction. We consider the inverse problem of gravimetry, inverse conductivity and scattering problems, and similar inverse obstacle problems for hyperbolic and parabolic equations. We expose mostly known results and some new ideas and approaches. In conclusion, we list several open research problems of significance for theory and applications.

The effects of consequences on patterns of social interaction: a quasi-experimental approach to reinforcement in natural interaction.

Abstract: Research on social interaction has consistently documented the existence of mutual interdependencies between the behavior of 1 person and reactions to that behavior by others in the social environment. The concept of social reinforcement, although often used to explain acquisition and change in interaction patterns defined by such interdependencies, is difficult to apply to interaction observed in natural settings. On the basis of extended observation of the interaction of 2 mother-child dyads, the procedures needed to assess the effects of naturally occurring consequences on interactional patterns are detailed in this study. Reliable mother action-child reaction patterns were first identified, and the effect of maternal consequences for those patterns on the probability of their subsequent occurrence was assessed. Positive consequences were associated with increases, and negative consequences with decreases, in the probability of a child reacting to the next occurrence of the maternal action when compared to the base-rate probability of that action-reaction pattern. Thus consequences affect momentary shifts around the baseline probability of interactional patterns. Positive consequences were also associated with short-term increases, and negative consequences with short-term decreases, in the base-rate probability of interactional patterns.

Adaptive information-sharing for privacy-aware mobile social networks

Abstract: Personal and contextual information are increasingly shared via mobile social networks. Users' locations, activities and their co-presence can be shared easily with online "friends", as their smartphones already access such information from embedded sensors and storage. Yet, people usually exhibit selective sharing behavior depending on contextual attributes, thus showing that privacy, utility, and usability are paramount to the success of such online services. In this paper, we present SPISM, a novel information-sharing system that decides (semi-)automatically whether to share information with others, whenever they request it, and at what granularity. Based on active machine learning and context, SPISM adapts to each user's behavior and it predicts the level of detail for each sharing decision, without revealing any personal information to a third-party. Based on a personalized survey about information sharing involving 70 participants, our results provide insight into the most influential features behind a sharing decision. Moreover, we investigate the reasons for the users' decisions and their confidence in them. We show that SPISM outperforms other kinds of global and individual policies, by achieving up to 90% of correct decisions.

An Experimental Procedure for the Extinction of Smoking Behavior

Abstract: Past and present methods of smoking abatement are cavalierly reviewed and found to be lacking. Three new strategies of behavior modification—contract management, convert sensitization, and contingency management—are described in their successful application to a statistically unimpressive sample (N = 2). Suggestions are offered for systematic research on the problem of smoking control and the broader implications of these strategies for the field of behavior modification are discussed.
