Ammonium oxalate treatment: Evaluation by μ-Raman mapping of the penetration depth in different plasters

This study is focused on the evaluation by μRaman mapping of the penetration depth achieved by ammonium oxalate treatment in different plaster specimens, a hot issue in the conservation field. The role of the carbonatic aggregate particles and the influence of the different variables of the treatment on the penetration depth and on the distribution of the newly-formed phase (whewellite) have been ascertained. Based on the results of μRaman mapping, analyses with Field Emission Scanning Electron Microscopy have been carried out in order to observe the whewellite crystals and the carbonatic aggregate particles involved in the reaction with ammonium oxalate.

How Heritable are Parental Sensitivity and Limit-Setting? A Longitudinal Child-Based Twin Study on Observed Parenting

We examined the relative contribution of genetic, shared environmental and non-shared environmental factors to the covariance between parental sensitivity and limit-setting observed twice in a longitudinal study using a child-based twin design. Parental sensitivity and parental limit-setting were observed in 236 parents with each of their same-sex toddler twin children (M_age = 3.8 years; 58% monozygotic). Bivariate behavioral genetic models indicated substantial effects of similar shared environmental factors on parental sensitivity and limit-setting and on the overlap within sensitivity and limit-setting across 1 year. Moderate child-driven genetic effects were found for parental limit-setting in year 1 and across 1 year. Genetic child factors contributing to explaining the variance in limit-setting over time were the same, whereas shared environmental factors showed some overlap.     

Investigating Neutralization Strategies in Digital Piracy: The Role of Content Preferences and Social Norms

ABSTRACT

Digital piracy is perceived as a victimless crime and therefore still challenges media industries. According to the neutralization theory, criminal behavior is more likely if individuals are able to justify it. As little is known about inhibitors and drivers of these cognitive processes, the current study investigated such preconditions by linking neutralization to social norms and content preferences (movies and series) in order to explain piracy attitudes and behavior. Results of an online survey which adopted a conjoint-task showed that attitudes toward digital piracy mediate neutralization effects on digital piracy behavior. Injunctive norms and the preference for independent movies foster neutralization effects.
