Managing shame and guilt in addiction: A pathway to recovery.

Addict Behav 2021 Apr 17;120:106954. Epub 2021 Apr 17.

Macquarie University, FAHA FASSA, Centre for Agency Values and Ethics, Faculty of Arts, Department of Philosophy, Australia. Electronic address:

A dominant view of guilt and shame is that they have opposing action tendencies: guilt- prone people are more likely to avoid or overcome dysfunctional patterns of behaviour, making amends for past misdoings, whereas shame-prone people are more likely to persist in dysfunctional patterns of behaviour, avoiding responsibility for past misdoings and/or lashing out in defensive aggression. Some have suggested that addiction treatment should make use of these insights, tailoring therapy according to people's degree of guilt-proneness versus shame-proneness. In this paper, we challenge this dominant view, reviewing empirical findings from others as well as our own to question (1) whether shame and guilt can be so easily disentangled in the experience of people with addiction, and (2) whether shame and guilt have the opposing action tendencies standardly attributed to them.

Faculty of Agriculture and Life Sciences, University of Maribor, Pivola 10, 2311 Hoce, Slovenia. Electronic address:

Near infrared (NIR) spectra are collected as a high amount of absorption values which usually greatly exceeds the sample size. Variable selection methods are employed in NIR spectroscopy to avoid "curse of dimensionality" related issues. In this paper, we examined the interpretability of selected variables, that is, how much selected wavelengths are related to the chemical structure of the materials studied, and if the relation is important for classification performance.

The adsorption of Zonyl FSN-100 (FSN100, having an average 14 oxyethylene units and 6 -CF groups) and Zonyl FSO-100 (FSO100, having an average 10 oxyethylene units and 5 -CF groups) as well as of their mixtures with p-(1,1,3,3-tetramethylbutyl) phenoxypoly(ethylene glycols) having 10, 16 and 8 oxyethylene groups in molecule (TX100, TX165, TX114) and cetyltrimethylammonium bromide (CTAB) at the solution-air and polytetrafluoroethylene (PTFE)-solution and polymethyl methacrylate (PMMA)-solution interfaces as well as the composition of the surface mixed layer was discussed based on the literature data. The adsorption properties of nonionic fluorocarbon surfactants were compared to those of the classical ones on the basis of the Gibbs standard free energy of adsorption determined by different ways and the intermolecular interactions of the surfactant molecules through the water phase. The synergetic effect in the reduction of the water surface tension by the mixture of fluorocarbon and classical nonionic surfactant was shown and explained by the comparison of the composition of the mixed surface layer to those in the bulk phase.
