Despite the growth of underemployment in United States, relatively little theoretical or empirical attention has been paid to this phenomenon. This article presents a multidimensional conceptualization terms education, work duties, field employment, wages, and permanence job. The then testable propositions on both hypothesized antecedents (e.g., economic factors, job characteristics, career history, search strategies, demographics) consequences attitudes, overall psychological well-being,...
Severe forms of depression have been linked to hyperactivity the subcallosal cingulate cortex. The ability stimulate cortex or associated circuits noninvasively and directly would maximize number patients who could receive treatment. To this end, we developed an ultrasound-based device for effective noninvasive modulation deep brain circuits. Here describe application tool individual with treatment-resistant depression.
Abstract Transcranial focused ultrasound provides noninvasive and reversible approaches for precise personalized manipulations of brain circuits, with the potential to transform our understanding function treatments dysfunction. However, effective applications in humans have been limited by human head, which attenuates distorts severely unpredictably. This has led uncertain intensities delivered into brain. Here, we address this lingering barrier using a direct measurement approach that can...
Direct interventions into deep brain circuits constitute promising treatment modalities for chronic pain. Cingulotomy and stimulation targeting the anterior cingulate cortex have shown notable improvements in unpleasantness of pain, but these require surgeries. In this study, we developed an approach that can modulate affective hub entirely noninvasively, using low-intensity transcranial-focused ultrasound. Twenty patients with pain received two 40-minute active or sham protocols were...
Low-intensity focused ultrasound provides the means to noninvasively stimulate or release drugs in specified deep brain targets. However, successful clinical translations require hardware that maximizes acoustic transmission through skull, enables flexible electronic steering, and accurate reproducible targeting while minimizing use of MRI. We have developed a device addresses these practical requirements. The delivers temporal parietal skull windows, which minimize attenuation distortions...
Rumination-focused cognitive behavioral therapy (RF-CBT) is designed to reduce depressive rumination or the habitual tendency dwell on experiences in a repetitive, negative, passive, and global manner. RF-CBT uses functional analysis, experiential exercises, repeated practice identify change ruminative habit. This preregistered randomized clinical trial (NCT03859297, R61) replication of initial work. We hypothesized concurrent reduction both self-reported cross-network connectivity between...
Childhood maltreatment (CM) is associated with negative mental health outcomes. Many studies conceptualize resilience as experiencing CM without developing psychopathology (primary resilience). However, some people may develop subsequent but recover and demonstrate higher global functioning (secondary This study investigated the role of salience emotion network (SEN) (including amygdala, subgenual anterior cingulate cortex, insula) cognitive control (CCN) dorsolateral prefrontal inferior...
Divergent age-related functional brain connectivity in autism spectrum disorder (ASD) has been observed using resting-state fMRI, although the specific findings are inconsistent across studies. Common statistical regression approaches that fit identical models networks may contribute to these inconsistencies. Relationships among have reported follow unique nonlinear developmental trajectories, suggesting need for flexible modeling. Here we apply generalized additive (GAMs) flexibly adapt...

This study examined the relationships between older workers’ time usage and their retirement anxiety. Specifically, we proposed that individuals’ current structure quality of work would be positively associated with In turn, level anxiety was postulated to intended age willingness accept bridge employment, but negatively expected satisfaction. Data were collected via questionnaire surveys from 204 workers aged 40 years above analysed structural equation modelling. As predicted, found related...
Strategies to link impulsivity and self-injurious behaviors (SIBs) show highly variable results, may differ depending on the measure used. To better understand this lack of consistency, we investigated correlations between self-report behavioral impulsivity, inhibitory control, SIBs, rumination. We included participants aged 13-17 years with either current or remitted psychopathology who have (n = 31) do not 14) a history SIBs. Participants completed measures Rumination Responsiveness Scale...
Abstract Introduction Rumination, or repetitive and habitual negative thinking, is associated with psychopathology related behaviors in adolescents, including non‐suicidal self‐injury (NSSI). Despite the link between self‐reported rumination NSSI, there limited understanding of how represented at neurobiological level among youth NSSI. Method We collected neuroimaging data from 39 adolescents current past NSSI remitted major depression. Participants completed a induction fMRI task,...
Abstract Background Anesthetic agents including ketamine and nitrous oxide have shown antidepressant properties when appropriately dosed. Our recent open-label trial of propofol, an intravenous anesthetic known to elicit transient positive mood effects, suggested that it may also produce robust durable effects administered at a high dose elicits electroencephalographic (EEG) burst-suppression state. Here we report findings from randomized controlled ( NCT03684447 ) compared two doses...
Trait rumination is a habitual response to negative experiences that can emerge during adolescence, increasing risk of depression. correlated with poor inhibitory control (IC) and altered default mode network (DMN) cognitive (CCN) engagement. Provoking state in high ruminating youth permits investigation IC at the neural level, highlighting potential treatment targets. Fifty-three high-ruminating were cued an unresolved goal provoked rumination, then completed modified Sustained Attention...
Abstract Hydrologic processes associated with intermountain cold-season precipitation in the Upper Colorado River basin have important impacts on avalanche forecasting and water resource management.
