Community Participation in Native American and White Individuals After Traumatic Brain Injury: A 5-Year Longitudinal Model Systems Study.

Purpose/objective: This study examined (a) differences in demographic and injury-related characteristics following traumatic brain injury (TBI) between Native American and White individuals; (b) differences in community participation between Native American and White individuals with TBI at 1, 2, and 5 years after TBI; and (c) whether demographic or injury-related characteristics account for community participation disparities.

Research Method/design: A sample of 63 Native American individuals demographically matched to 63 White individuals (n = 126) was enrolled while on acute rehabilitation for moderate or severe TBI. Baseline demographic and injury-related characteristics were collected at this time and the Participation Assessment with Recombined Tools (PART-O) measure of community participation at 1, 2, and 5 years after TBI.

Marital Stability During the Year After Traumatic Brain Injury in an Ecuadorian Sample: A Repeated-Measures Study.

Traumatic brain injury (TBI) is a major cause of death and disability worldwide and often leads to long-lasting emotional, physical, and cognitive changes and results in reduced functioning across multiple domains. These changes often lead to strain in marital relationships as the uninjured spouse grapples with adapting to the changes in their partner. The purpose of this study was to examine the probability of marital stability after TBI at 6 and 12 months following injury (i.

Efficient learning of ground and thermal states within phases of matter.

We consider two related tasks: (a) estimating a parameterisation of a given Gibbs state and expectation values of Lipschitz observables on this state; (b) learning the expectation values of local observables within a thermal or quantum phase of matter. In both cases, we present sample-efficient ways to learn these properties to high precision. For the first task, we develop techniques to learn parameterisations of classes of systems, including quantum Gibbs states for classes of non-commuting Hamiltonians.

Development and validation of the Telepsychology Facilitators Scale: A national study.

This study developed and validated the Telepsychology Facilitators Scale (TFS), a novel measure that uses the theory of reasoned action and technology acceptance model as frameworks to assess factors that influence psychologists' openness to using telepsychology. At the beginning of the COVID-19 pandemic, an online sample of 2,619 psychologists completed initial items considered for the TFS, along with a measure assessing their actual use of telepsychology. The sample was split in half, with a preliminary exploratory factor analysis ultimately revealing a 13-item general scale with four distinct subscales (Positive Attitudes, Facilitating Infrastructure, Organizational Support, and External Policies).

Patterns of Alcohol Use in Hispanic Individuals with TBI over the Ten Years Post-Injury: A Model Systems Study.

The study's aim was to examine alcohol consumption patterns and predictors of consumption across time among Hispanics with traumatic brain injury (TBI) in the U.S. within ten years post-injury.

Factors Associated with Inhaled Bronchodilator and Oral Corticosteroid Use in Young Children with First Lower Respiratory Tract Infection.

Objectives: To examine factors associated with claims for and potential overuse of inhaled bronchodilators (IBs) and oral corticosteroids (OCSs) for children <2 years old at first lower respiratory tract infections (LRTIs).

Study Design: Retrospective cohort study using Colorado All Payer Claims data from 2009 through 2019. Children with asthma were excluded.

Trajectories of life satisfaction in Hispanic individuals over the 10 years after traumatic brain injury: A model systems study.

Purpose: To identify life satisfaction trajectories at 1-10 years post-traumatic brain injury (TBI) and examine which demographic and injury characteristics at the time of injury are associated with those trajectories.

Methods: Participants included 1,051 Hispanic individuals from the multi-site, longitudinal TBI Model Systems (TBIMS) database. Individuals were enrolled after sustaining a TBI and while undergoing inpatient rehabilitation at a TBIMS site; they were included if they completed the Satisfaction with Life Scale during one or more follow-up data collections at 1, 2, 5, or 10 years after TBI.

Barriers and Facilitators to Psychologists' Telepsychology Uptake during the Beginning of the COVID-19 Pandemic.

The COVID-19 pandemic transformed the delivery of psychological services as many psychologists adopted telepsychology for the first time or dramatically increased their use of it. The current study examined qualitative and quantitative data provided by 2619 practicing psychologists to identify variables facilitating and impeding the adoption of telepsychology in the U.S.

Uncomputably complex renormalisation group flows.

Renormalisation group methods are among the most important techniques for analysing the physics of many-body systems: by iterating a renormalisation group map, which coarse-grains the description of a system and generates a flow in the parameter space, physical properties of interest can be extracted. However, recent work has shown that important physical features, such as the spectral gap and phase diagram, may be impossible to determine, even in principle. Following these insights, we construct a rigorous renormalisation group map for the original undecidable many-body system that appeared in the literature, which reveals a renormalisation group flow so complex that it cannot be predicted.

Employment probability trajectories in hispanics over the 10 years after traumatic brain injury: A model systems study.

Background: Research has found that Hispanics with traumatic brain injury (TBI) have reduced functional outcomes compared to non-Hispanic Whites, including lower probabilities of post-injury employment. However, previous studies were cross-sectional, combined racial/ethnic minority groups, and did not examine the factors that predict return to work of Hispanics longitudinally.

Objective: To determine the demographic and injury-related predictors of employment probability trajectories during the first 10 years after TBI.

[Fp(CH)], [η-CpRu(CO)(CH)], and [η-CpOs(CO)(CH)]: A Complete Set of Group 8 Metal-Methane Complexes.

Here, we report the NMR spectroscopic analysis of the group 8 transition metal methane σ-complexes [η-CpM(CO)(CH)][Al(OC(CF))] (M = Fe, Ru) at -90 °C in the weakly coordinating solvent 1,1,1,3,3,3-hexafluoropropane. The iron(II)-methane complex has a H resonance at δ -4.27, a C resonance at δ -53.

Trajectories of Cognitive and Motor Functional Independence in Hispanic Individuals During the 10 yrs After Traumatic Brain Injury.

Objective: This study examined demographic and injury-related predictors of cognitive and motor functional independence in Hispanics with traumatic brain injury at years 1, 2, 5, and 10 after hospital discharge.

Design: Hispanic participants ( n = 1360) from the TBI Model Systems Study were included if they had at least one Functional Independence Measure (FIM) Cognitive and Motor score at any time point (years 1, 2, 5, or 10). Hierarchical linear modeling was used to examine baseline predictors of FIM Cognitive and Motor trajectories across this period.

Progressive loss of hearing and balance in superficial siderosis due to occult spinal dural defects.

Purpose: Superficial siderosis, a progressive, debilitating, neurological disease, often presents with bilateral impairment of auditory and vestibular function. We highlight that superficial siderosis is often due to a repairable spinal dural defect of the type that can also cause spontaneous intracranial hypotension.

Methods: Retrospective chart review of five patients presenting with moderate to severe, progressive bilateral sensorineural hearing loss as well as vestibular loss.

Pain, mental health, life satisfaction, and understanding from others in veterans with spinal cord injury.

Purpose/objective: This study evaluated the relationships among pain, mental health symptom severity, life satisfaction, and understanding from others in veterans with spinal cord injury (SCI).

Research Method/design: A sample of 221 individuals with SCI were interviewed by a psychologist during their annual evaluation in a Veterans Affairs medical center in an urban Mid-Atlantic region. Participants completed single-item, Likert-scale measures of life satisfaction (McGuire Health Impact on Participation [M-HIP]), pain severity (M-HIP), and understanding of others (from a modified Appraisals of DisAbility Primary and Secondary Scale-Short Form [ADAPSS-sf]), along with the Patient Health Questionnaire-4 (PHQ-4), a measure of mental health symptom severity.

Binding methane to a metal centre.

The σ-alkane complexes of transition metals, which contain an essentially intact alkane molecule weakly bound to the metal, have been well established as crucial intermediates in the activation of the strong C-H σ-bonds found in alkanes. Methane, the simplest alkane, binds even more weakly than larger alkanes. Here we report an example of a long-lived methane complex formed by directly binding methane as an incoming ligand to a reactive organometallic complex.

Relations among Stigma, Quality of Life, Resilience, and Life Satisfaction in Individuals with Burn Injuries.

This study examined the relations among burn stigma, quality of life, resilience, and life satisfaction, hypothesizing that higher stigma and lower burn-related quality of life would lead to lower life satisfaction; however, resilience would moderate this relation. A sample of 89 participants was recruited from an outpatient clinic of a burn center in a critical care hospital. Participants completed a battery of measures assessing these constructs.

Association between early childhood lower respiratory tract infections and subsequent asthma.

Objective: We examined the relationship between recurrent lower respiratory tract infections (LRTI) in young children and subsequent childhood asthma outcomes.

Methods: Retrospective cohort study using 2009-2017 Colorado All Payer Claims Database to assess 0- to 2-year-old children with visits due to LRTI and acute gastroenteritis (AGE). The primary exposure was number of LRTI visits prior to 2 years of age.

Sharing the load: How a personally coloured calculator for grapheme-colour synaesthetes can reduce processing costs.

Synaesthesia refers to a diverse group of perceptions. These unusual perceptions are defined by the experience of concurrents; these are conscious experiences that are catalysed by attention to some normally unrelated stimulus, the inducer. In grapheme-colour synaesthesia numbers, letters, and words can all cause colour concurrents, and these are independent of the actual colour with which the graphemes are displayed.

Psychometric investigation of the affiliate stigma scale in Mexican Parkinson's disease caregivers: Development of a short form.

Background: Parkinson's disease (PD) caregivers, particularly in Latin America, may experience high levels of affiliate stigma due to their association with a person having a disability. The most common measure used of this construct in the literature, the Affiliate Stigma Scale, was validated using non-standard and questionable methods.

Objective: The purpose of this study was to investigate the factor structure and psychometric properties of the Spanish version of the Affiliate Stigma Scale with PD caregivers in Mexico using more widely accepted psychometric approaches including confirmatory and exploratory factor analyses (CFAs, EFAs).
