NeSiFC: Neighbors' Similarity-Based Furred Group Detection Using Altered Neighborhood Random Stroll.
Previous studies examining the factor structure of attention-deficit/hyperactivity disorder (ADHD) symptoms in adults using self-report measures have shown mixed results, supporting two-, three-, and bifactor solutions. The current study further investigated the structure of ADHD symptoms in adults using the Current Symptoms Scale and rigorous model evaluation in a sample of 892 college students. Confirmatory factor analysis was used to analyze and compare five-factor structures; a single-factor model, a two-factor model, a three-factor model, and two bifactor models. A single-factor model with correlated residuals best fit the data. Factor correlations with nearly all related constructs (i.e., symptoms of oppositional defiant disorder, depression, impairment, previous ADHD diagnosis, grades, and substance use) were significant in the expected directions and the model was invariant across gender. These findings contribute to a growing body of work suggesting a unidimensional factor may best represent ADHD symptoms in adults. Implications are discussed.OBJECTIVE. The purpose of this study was to analyze recent trends in abdominal imaging utilization in the Medicare population. MATERIALS AND METHODS. Medicare Part B databases for 2004-2016 were reviewed, and all Current Procedural Terminology codes pertaining to noninvasive imaging of the abdomen and pelvis were identified. Codes were grouped into six categories CT and CT angiography (CTA), MRI and MR angiography (MRA), ultrasound, radionuclide imaging, radiography, and gastrointestinal fluoroscopy. Annual utilization rates per 1000 Medicare beneficiaries were calculated. Medicare physician specialty codes were used to identify studies performed by radiologists versus nonradiologist physicians. Reimbursements were determined. RESULTS. Total abdominal imaging utilization decreased from 558.0 examinations per 1000 Medicare beneficiaries in 2004 to 441.9 in 2016 (-20.8%). CT and CTA examinations increased by 22.5% from 2004 to 2010, followed by a sharp drop in 2011 caused by code bundling. From 2011 to 2016, CTby radiologists.Research on the effects of restricted housing on inmate well-being indicates mild to moderate psychological effects and barriers opportunities for treatment and positive growth. Yet, there are few interventions tailored both to the needs of this high-risk population and to the institutional constraints of their environment. Given the financial and safety burdens associated with housing someone in segregation compared to the general population, correctional psychology should focus on developing programs that work. Using a prepost design, this study presents findings from a pilot investigation (N = 39) on the effects of a new, largely self-directed program (Stepping Up, Stepping Out [SUSO]) for inmates with mental and behavioral health concerns who are placed in restrictive settings. Results suggest that SUSO is associated with meaningful reductions in overall emotional distress and criminal attitudes; however, improvements in more stable criminal thinking patterns (i.e., distorted cognitions that are used to justify and support antisocial behavior; see Walters, 2012) were not observed. Overall, posttreatment working alliance was rated favorably by program participants. Demographic and preintervention comparisons between program completers and dropouts are also reported. Though preliminary findings suggest SUSO is a promising intervention for alleviating distress and aspects of criminal risk for inmates placed in restricted housing, future research should assess fidelity and engagement leading to a randomized controlled trial to determine the effectiveness of this program.

We also examine the identity labels that DACA recipients adopt for themselves (i.e., avowed). Envonalkib Method Forty semistructured interviews were conducted with DACA recipients who attend a 2- or 4-year college in California. Results Our findings reveal that DACA recipients have different meanings for ascribed identity labels. Some of these meanings have positive connotations and denotations, which may help to construct a positive self-view. Nonetheless, most of the emergent themes in our study show that DACA recipients perceive that ascribed identity labels have negative connotations and denotations. To create more positive representations of undocumented immigrants, DACA recipients use certain labels to describe themselves. Conclusion Consideration of the ascribed and avowed identities of DACA recipients is important because such identities might reflect and influence others' views of undocumented immigrants and affect undocumented immigrants' self-view.

The InCl3-catalyzed reaction progressed via enamine formation, Michael addition, intramolecular cyclization, and intramolecular iminium ion cyclization steps. Notably, this high atom economic approach (-2H2O) allowed the generation of four new bonds (1 C-C and 3 C-N or 1 C-C, 1 C-O and 2 C-N) and two heterocyclic rings in a single operation.Novel bimetallic zinc acetate complexes supported by heteroscorpionate ligands have been developed for the ring-opening copolymerization of cyclohexene oxide and CO2 and the terpolymerization of cyclohexene oxide, phthalic anhydride, and CO2. Heteroscorpionate ligands precursors L1-L3 were reacted with two equivalents of zinc acetate to afford the dinuclear zinc complexes [Zn(κ3-bpzappe)(μ-O2CCH3)3-Zn(HO2CCH3)] (1), [Zn(κ3-bpzbdmape)(μ-O2CCH3)3-Zn(HO2CCH3)] (2), and [Zn(κ3-bpzbdeape)(μ-O2CCH3)3Zn(HO2CCH3)] (3) in excellent yields. The molecular structure of these compounds was determined spectroscopically and confirmed by X-ray diffraction analysis. Zinc acetate complexes 1-3 were screened as catalysts for the copolymerization of cyclohexene oxide and CO2 to produce poly(cyclohexene)carbonate, and complex 3 was found to be the most active catalyst for this process in the absence of a cocatalyst. Furthermore, the terpolymerization of cyclohexene oxide, phthalic anhydride, and CO2 was studied using the combination of complex 3 and 4-dimethylaminopyridine as catalyst system yielding the corresponding polyester-polycarbonate materials.
