We have studied the stability of the smallest long-lived all carbon molecular dianion (C_{7}^{2-}) in new time domains and with a single ion at a time using a cryogenic electrostatic ion-beam storage ring. We observe spontaneous electron emission from internally excited dianions on millisecond timescales and monitor the survival of single colder C_{7}^{2-} molecules on much longer timescales. We find that their intrinsic lifetime exceeds several minutes-6 orders of magnitude longer than established from earlier experiments on C_{7}^{2-}.

Background: Psychopathic traits have been associated with impaired emotion recognition in criminal, clinical and community samples. A recent study however, suggested that cognitive impairment reduced the relationship between psychopathy and emotion recognition. We therefore investigated if reasoning ability and psychomotor speed were impacting emotion recognition in individuals with psychotic spectrum disorders (PSD) with and without a history of aggression, as well as in healthy individuals, more than self-rated psychopathy ratings on the Triarchic Psychopathy Measure (TriPM).

Article Synopsis
  • Negative ions play a crucial role in various scientific fields such as interstellar chemistry and anti-matter research, where their unique properties are influenced by electron-correlation effects.
  • Traditional methods for studying these ions face challenges due to their loosely bound nature and limited optical transitions, hindering high-resolution detection techniques.
  • A new method has been developed that accurately measures negative ion binding energies with significantly higher precision, utilizing laser manipulation and a cryogenic ion-beam storage ring, leading to a reported electron affinity of 1.461 112 972(87) eV for oxygen.

Background: Some aggressive acts committed by individuals with psychotic spectrum disorders (PSD) are understandable in the context of interpersonal conflict or goal attainment, yet others are unpredictable, arising from delusions or hallucinations (psychotically driven aggressive acts, PDA). It is unknown if there are underlying differences in cognitive or perceptive social cognition in relation to aggression motivation in PSD.

Method: We compared differences in social cognition performance between 49 individuals with PSD who had committed PDA with those exhibiting other types of aggression (n = 31) (non-PDA) and to community controls (n = 81) on the Swedish version of Double Movie for the Assessment of Social Cognition - Multiple Choice (DMASC-MC).

One of the most important properties influencing the chemical behavior of an element is the electron affinity (EA). Among the remaining elements with unknown EA is astatine, where one of its isotopes, At, is remarkably well suited for targeted radionuclide therapy of cancer. With the At anion being involved in many aspects of current astatine labeling protocols, the knowledge of the electron affinity of this element is of prime importance.

Social interactions require decoding of subtle rapidly changing emotional cues in others to facilitate socially appropriate behaviour. It is possible that impairments in the ability to detect and decode these signals may increase the risk for aggression. Therefore, we examined violent offenders with schizophrenia spectrum disorders (SSD) and compared these with healthy controls on a computerized paradigm of briefly presented double masked faces exhibiting 7 basic emotions.

Article Synopsis
  • Researchers at Stockholm University's DESIREE facility measured the cooling lifetimes and detachment energies for three sizes of carbon anions (C3, C4, and C5) in a super-cool environment with low pressure.
  • They created two-dimensional photodetachment spectra that showed how the anions lost energy over time, revealing cooling lifetimes of 3.1 s, 6.8 s, and 24 s for each respective anion size.
  • The study's findings confirmed the occurrence of radiative cooling and established a model for simulating cooling dynamics, which could be useful for exploring other molecular anions in future research.

We investigated whether psychopathy-associated personality traits and behavioral styles affect the manner in which homicides are committed or the motives underlying them. Using three nationwide registries and an in-house homicide database based on court verdicts, we identified all cases of homicide in Sweden during the years 2007, 2008 and 2009. In 72 male offenders who had undergone assessment using the Psychopathy Checklist - Revised (PCL-R), the manner of homicide was categorized as instrumental or expressive, and the motive as belonging to one of five categories: (1) intimate-partner or family-related homicide; (2) homicide occurring during altercations, (3) robberies or burglaries, or (4) criminal conflicts; or (5) sexual homicide.

Introduction: Repetitive negative thinking (RNT) is reported in a wide variety of emotional disorders, although it is most often associated with either depression or anxiety disorders, assessed as symptoms of rumination and worry. Early detection of indicators for RNT across disorders is needed. To this end we explored the psychometric properties of a transdiagnostic measure, i.

Infections during brain development appear to contribute to cognitive impairment and aggressive behavior, as well as to a number of developmental mental disorders closely associated with violent criminal behavior. Yet, no study has thus far ever investigated whether infections during brain development increases the risk of violent criminality later in life. In this population-based cohort study, about 2.

A sputter ion source with a solid graphite target has been used to produce dianions with a focus on carbon cluster dianions, C, with n = 7-24. Singly and doubly charged anions from the source were accelerated together to kinetic energies of 10 keV per atomic unit of charge and injected into one of the cryogenic (13 K) ion-beam storage rings of the Double ElectroStatic Ion Ring Experiment facility at Stockholm University. Spontaneous decay of internally hot C dianions injected into the ring yielded C anions with kinetic energies of 20 keV, which were counted with a microchannel plate detector.

Background: Offenders with mental disorders constitute a particularly exposed group in society, with high rates of morbidity, mortality, and social deprivation. Often thought of primarily as perpetrators, these individuals may also be subjected to violence. Previous research indicates that violent victimization during lifespan is a risk factor for violent perpetration among psychiatric patients, but victimization studies on the group of offenders with mental disorders are scarce.

Cross-cultural investigation of psychopathy measures is important for clarifying the nomological network surrounding the psychopathy construct. The Psychopathic Personality Inventory-Revised (PPI-R) is one of the most extensively researched self-report measures of psychopathic traits in adults. To date however, it has been examined primarily in North American criminal or student samples.

Research on psychopathic personality has been dominated by a focus on criminality and social deviance, but some theoretical models argue that certain putatively adaptive features are important components of this construct. In 3 samples (forensic mental health practitioners, probation officers and a layperson community sample), we investigated adaptive traits as conceptualized in the Triarchic model of psychopathy (Patrick et al., 2009), specifically the relevance of boldness to construals of psychopathic personality.

Article Synopsis
  • Previous research indicates that female violent offenders are more likely than males to be required by courts to receive hospital treatment for mental health issues.
  • The study aimed to determine if there is a bias towards recommending hospital treatment for female versus male offenders diagnosed with mental disorders.
  • Findings showed no significant gender bias in assessments for hospital treatment, though a female offender with mental retardation was deemed at higher risk for recidivism, suggesting a need for further investigation into this discrepancy.
