The Bologna-Barcelona axis between Criminal Law Dogmatics and Critical Sociology of punitive control. Hidden Continuities and Apparent Overcomings
Authors: Gatti Carlo
Published: December 2023

This article aims to highlight the importance of the link between Bologna and Barcelona, consisting of an epistemic and methodological convergence in the approach to the criminal question and, in particular, to the problem of penal selectivity.  If on the one hand this link cannot be eliminated, on the other it is exposed to a series of attempts at obfuscation by the dominant legal and criminological ideology, which is even reflected in autobiographical contingencies that add an anecdotal dimension to the discussion. At the same time, the recovery of this link imposes a reflection on the contemporary criminological debate, since the distinctive features of Italian-Iberophone critical criminology clash with some premises of the most recent and advanced trends in terms of critical potential, in particular the zemiological approach. One example is the role that criminal dogmatics plays within the sociological analysis of the penal system following Franco Bricola’s lesson, and the meaning of this methodological choice in terms of transdisciplinarity and political radicalism.  Our conclusion is that a better coordination between critical traditions is needed: one that aims at overcoming linguistic barriers and starts with a systematic review of the existing critical arsenal before any headlong rush
Lifestyle, Coping Resources, and Trauma Symptoms: Predicting Post-traumatic Growth
Authors: Leeman Michael S. , Castleberry Joshua , Chang Catherine Y.
Published: December 2023

ABSTRACT: Interpersonal trauma influences levels of post-traumatic stress and post- traumatic growth. Several factors are associated with post-traumatic growth, such as symptom severity, personality traits, and coping resources (Tedeschi & Calhoun, 2004). This study examined the role of trauma symptoms, belonging and social interest (BSI), tension control (TC), social support (SS), and post-traumatic growth (PTG), and a moderated mediation model in a sample of individuals who experienced interpersonal trauma. Both SS and TC contributed to PTG. SS and TC mediated the association between trauma symptoms and PTG. BSI moderated trauma symptoms in SS and trauma symptoms in TC. High BSI accounted for variance in the relationship between trauma symptoms and SS, and lower BSI accounted for more variance between trauma symptoms and TC.
Review of measurements and imaging of cytochrome-c-oxidase in humans using near-infrared spectroscopy: an update
Authors: Leadley Georgina , Austin Topun , Bale Gemma
Published: December 2023

This review examines advancements in the measurement and imaging of oxidized cytochrome-c-oxidase (oxCCO) using near-infrared spectroscopy (NIRS) in humans since 2016. A total of 34 published papers were identified, with a focus on both adult and neonate populations. The NIRS-derived oxCCO signal has been demonstrated to correlate with physiological parameters and hemodynamics. New instrumentation, such as systems that allow the imaging of changes of oxCCO with diffuse optical tomography or combine the oxCCO measurement with diffuse correlation spectroscopy measures of blood flow, have advanced the field in the past decade. However, variability in its response across different populations and paradigms and lack of standardization limit its potential as a reliable and valuable indicator of brain health. Future studies should address these issues to fulfill the vision of oxCCO as a clinical biomarker.
