From the Inside: The Meaning of Probation to Probationers

Beyond considerations of relative punitiveness, very little is known about how offenders understand the experience of serving a probation sentence. The current study surveyed offenders currently on probation to assess the extent to which they believed their sentence was rehabilitative, incapacitative, deserved, and a deterrent to future offending. Perceptions that probation served no purpose and that it represented a game of manipulation and impression management were also investigated. The results showed that most probationers believed that their sentence was a deterrent, and it was rehabilitative and deserved. They also felt that probation served multiple purposes, and a minority of respondents perceived that there was no point to being on probation. The implications of these findings are discussed

Defensive reactions to health-promoting information: an overview and implications for future research

It is a common finding that recipients of threatening health-promoting information are motivated to dismiss or disregard the information, thus reacting defensively'. This article gives an overview of the literature on defensive reactions to health-promoting information. A distinction is made between: (1) avoidance, (2) denial, (3) cognitive reappraisal and (4) suppression. Although these defensive reactions have been studied repeatedly and thoroughly, we propose that a number of questions remain unanswered. First, little is known about whether avoidance, denial, cognitive reappraisal and suppression have distinct or similar effects on emotional experience and health-conducive behaviour. Second, little is known about the development of defensive reactions over time in case recipients are repeatedly exposed to health-promoting information, which is often the case in a real-life setting. In the present article, we present preliminary answers to these questions, suggesting that cognitive reappraisal has greater potential to result in effective emotion regulation and is more likely to impede healthy behaviour than the other three strategies. We also propose that defensive reactions to health-promoting information do not always reduce health-conducive responses but can co-occur with more adaptive responses or even facilitate them. Finally, we present a hypothesised model of the development of defensiveness over time

Electrochemistry and capacitive charging of porous electrodes in asymmetric multicomponent electrolytes

We present porous electrode theory for the general situation of electrolytes containing mixtures of mobile ions of arbitrary valencies and diffusion coefficients (mobilities). We focus on electrodes composed of primary particles that are porous themselves. The predominantly bimodal distribution of pores in the electrode consists of the interparticle or macroporosity outside the particles through which the ions are transported (transport pathways), and the intraparticle or micropores inside the particles, where electrostatic double layers (EDLs) are formed. Both types of pores are filled with electrolyte (solvent plus ions). For the micropores we make use of a novel modified-Donnan (mD) approach valid for strongly overlapped double layers. The mD-model extends the standard Donnan approach in two ways: (1) by including a Stern layer in between the electrical charge and the ions in the micropores, and (2) by including a chemical attraction energy for the ions to go from the macropores into the micropores. This is the first paper where the mD-model is used to model ion transport and electrochemical reactions in a porous electrode. Furthermore we investigate the influence of the charge transfer kinetics on the chemical charge in the electrode, i.e., a contribution to the electrode charge of an origin different from that stemming from the Faradaic reaction itself, e.g. originating from carboxylic acid surface groups as found in activated carbon electrodes. We show that the chemical charge depends on the current via a shift in local pH, i.e. “current-induced charge regulation.” We present results of an example calculation where a divalent cation is reduced to a monovalent ion which electro-diffuses out of the electrode.National Science Foundation (U.S.) (NSF Contract No. DMS 0948071)Massachusetts Institute of Technology.
