Using generalized estimating equations, the interaction between coping and cumulative-average NA was positively associated with momentary drinking, with some evidence for a stronger relation during the continuation of drinking. The interaction between enhancement motives and cumulative-average PA was positively associated with initiation but negatively associated with continuation of drinking. Our novel approach of using cumulative-average affect and distinguishing initiation and continuation of drinking allowed us to examine differential momentary patterns across the drinking episode, and results suggest that awareness of motives as well as affect leading up to and during drinking may be a useful intervention target.

PWID with borderline personality disorder (BPD) have increased risk of RSS, but it remains unclear what drives this association. This study used ecological momentary assessment (EMA) to study characteristics associated with BPD, and RSS among PWID. We recruited PWID, ages 18-35, through two Community Outreach Intervention Projects syringe service program sites in Chicago, Illinois. After a baseline interview, participants used a mobile phone app to respond to momentary surveys on mood, substance use, and injection risk behavior for two weeks. For each momentary assessment, ratings on negative mood descriptors were combined to create measures of total negative affect (NA), and NA components of dejection, shame, anger, irritability, and worry. RSS was defined by participant responses indicating that they had used a syringe that someone else had used. We estimated mixed effects logistic models, regressing RSS on baseline affect-related impulsivity, lagged momentary NA, and the interaction term. Out of 163 participants who completed at least two EMA assessments, 152 (93%) reported at least one injection event and had valid pre-injection mood assessments required to be included in the analysis. We found that affect-related impulsivity, combined with worried mood in the hours preceding the injection episode, predicted increased risk of RSS. PWID having difficulties with emotion regulation may be at increased risk of RSS during periods of anxiety or tension.

Although authenticity can be argued to benefit teamwork as authentic team members contribute their unique perspectives, it can also hinder teamwork if those unique perspectives are not heard and integrated. Using theory on groups as information processors, we propose that when team members both contribute their own unique perspectives (team mean authentic living), and try to understand each other's contributions (team mean perspective taking), a process of information elaboration occurs at the team level, which in turn leads to team performance. Study 1 tested these assumptions in 67 teams of students (N = 247), whereas Study 2 used 37 teams of employees (N = 194). Results support the hypothesized interaction between team mean authentic living and team mean perspective taking on team information elaboration such that the effects were positive when perspective taking was high but negative when it was low. In terms of team performance, although team information elaboration consistently predicted team performance in both studies, Study 1 could not confirm the hypothesized indirect effects, whereas Study 2 confirmed only the hypothesized positive indirect effect.

However, few investigations have examined the impact of microaggressions on Black college students' worries about their future employment and potential moderating factors. We examined whether there would be an association between microaggressions and worries about future employment. Furthermore, both social support and academic achievement (measured by grade point average) were purported to moderate this association. METHOD Secondary data analysis was used, with the study sample consisting of Black college students (n = 225) from a predominately White institution. Participants had a mean age of 20.43 years (SD = 1.79), with females comprising 74.80% of the sample. RESULTS Results revealed that social support buffered the effect of microaggressions for low-achieving students, while a buffering effect of social support was not found for high-achieving students. CONCLUSIONS Perceived social support offers some protection against the exposure of racial microaggressions, although high-achieving Black college students (the most vulnerable to potential isolation and academic pressure) may not benefit from overall social support.

This study reports the fabrication of two-dimensional molecular films with site-specific functionalities, forming microarrays at discrete locations. selleck kinase inhibitor Arrays of microsized gold disks were produced on a silicate membrane using microfabrication. On these arrays, orthogonal self-assembly of molecules was performed that can specifically bind to gold or silicate. The gold array elements were functionalized with a range of alkanethiols and the silicate with polymeric poly-l-lysine-grafted-poly(ethylene glycol) (PLL-PEG). selleck kinase inhibitor The surface functionalization on the gold disk array and the surrounding substrate was characterized at each step using X-ray photoelectron spectroscopy (XPS) to show that alkanethiols are specifically attached to the gold. PLL-PEG was used to provide resistance against nonspecific protein and cell adsorption and attached exclusively to the silicate. The effectiveness of the surface chemistry was validated by the selective self-assembly of a gold nanoparticle monolayer array on the gold regions. In a more sophisticated example, selective adhesion of MCF-7 cells to anti-EpCAM antibody modified gold areas of the gold-silicate surface was demonstrated to give a cell microarray. This study provides a general approach to fabricate chemical patterns on silicon-based devices with the convergence of microfabrication and material-specific surface modification, which may be useful to expand the functionalities and potential applications for patterned biomolecular films. Importantly, the ability to pattern surfaces with different surface chemistries is not limited to planar surfaces using this orthogonal surface-coupling approach.
