Closet #2347
In the beginning, my sculptural work was based on identity dilemnas and social distortions surrounding life as an adopted Interracial woman. Being of Caucasian and some African-American lineage, I am part of the most unaccepted racial taboo in society. The "Caucasian" and "AfricanAmerican" communities agree that sexual integration has and will cause confusion and I disease, within our so called "structured society". The collective White hysteria about "invisible black blood'', and the separation within the black community over color differences are but two examples of the discomfort caused by such mescegenation. These fears have forced society to establish laws and promote stereotypes to instill concrete boundaries. Our society creates classifications of race based on physical characteristics. Issues such as "passing for 'White'" are confronted by many Interracial people who have different racial features. Such an option is raised negatively by the "Black" community, believing it disloyal to One's "true" racial identity as well as to the "Black" community. The negativity's strength lies in the "one drop rule" and the haunted memory of slavery. The "one drop rule " states that children with any Black ancestry are to be defined and treated as Black individuals, not just as human beings without a racial identity, or as a racially mixed individuals of varying color. The issues of slavery have trapped the Black community into the state of mind of "never again". As the Jewish community is not expected to forgive and forget the Holocaust, the I Black community views the Interracial community as a reminder of slavery and White supremacy. The "White" society created the "One Drop Rule " to distinguish themselves from the "Mulattoes, Quadroons, and Octoroons" that were created between slave owners and slaves. This law established and maintained a loop hole for the "masters " to rape the slaves and hold no responsibility for the children produced by that violence. The Black community has strongly reinforced the "One Drop Rule" for the simple benefit of numbers. There is strength in numbers and the Black community understands that. Informal, but powerful social pressures deter those who can pass from doing so, and punish those who marry Whites. The rule has come to be considered essential to maintaining pride in the Black ethnic community. Closet #2437, has several different components. The main piece of the installation is a closet which represents the symbolic metaphor for a "conceptual closet". This closet illustrates how society's acceptance of this separitist illusion perpetuates exile and lack of acknowledgment. The meaning of this "constructed illusion" is that society has manipulated the manner in which Americans (as a collective unit) will view those who do not fit into the illusionary "norm". / The closet's random number #2437 is used to represent the fact that there are many communities and issues that society has forced into this "conceptual closet". </p

ranacapa: An R package and Shiny web app to explore environmental DNA data with exploratory statistics and interactive visualizations.
Environmental DNA (eDNA) metabarcoding is becoming a core tool in ecology and conservation biology, and is being used in a growing number of education, biodiversity monitoring, and public outreach programs in which professional research scientists engage community partners in primary research. Results from eDNA analyses can engage and educate natural resource managers, students, community scientists, and naturalists, but without significant training in bioinformatics, it can be difficult for this diverse audience to interact with eDNA results. Here we present the R package ranacapa, at the core of which is a Shiny web app that helps perform exploratory biodiversity analyses and visualizations of eDNA results. The app requires a taxonomy-by-sample matrix and a simple metadata file with descriptive information about each sample. The app enables users to explore the data with interactive figures and presents results from simple community ecology analyses. We demonstrate the value of ranacapa to two groups of community partners engaging with eDNA metabarcoding results
The discrimination of self from other as a component of empathy.
Despite the centrality of empathy in human social life, there is no widely agreed definition or characterization of the concept of empathy. A common thread in many of the proposed definitions, however, is that empathy presupposes the discrimination of self and other on the grounds that, to empathize with another individual, the mental state of the target individual must first be distinguished from the empathizer's own mental state. The purpose of this study is to investigate this proposal empirically. We employed a paradigm in which participants rated the emotional valence and degree of arousal of 93 facial expressions of mental states. We asked participants to infer the mental state represented by each facial expression (the Other condition) as well as to describe the effect of the expression on their own mental state (the Self condition). An absolute difference score between the Other and the Self conditions was used as an index of a capacity for self-other discrimination. Empathy was measured using the Interpersonal Reactivity Index. Results show that individuals high in trait empathy discriminate between self and other to a significantly greater degree when judging mental states than individuals low in trait empathy. This suggests that the capacity for self-other discrimination may be a component of the capacity for empathy and that future investigations of the concept of empathy ought to retain it.

Practice Report: Student Health Ambassadors at Residential Campuses Contribute to Safer Campus Living and Learning During the COVID-19 Pandemic
In summer 2020 six residential institutions of higher education (IHE) and the Mountain Area Health Education Center (MAHEC) in Western North Carolina chose a collaborative approach to mitigating COVID-19 infection rates on campus. This approach shares the practices and successes of this concerted effort with a focus on a large public, medium public, and small private IHE. The campuses promoted a healthy and safe culture through a rigorous and transformational learning experience and focused on engaging Student Health Ambassadors (SHAs) in applying the Diffusion of Innovations model to peer-topeer gain-framed messaging for health. Three institutions’ programs are presented and cross-case analysis is used to illuminate transferable promising practices. Promising transferable practices across the schools include: selecting the right students, strong institutional support, the three Ps (positive, proactive and prevention-focused), building leadership skills, and peer-led campus culture change. Transferable insights from the practices at three campuses focused on the role and impact of peer-to-peer student health ambassadors on campus to mitigate the spread of COVID-19
Improved gastrointestinal profile with diroximel fumarate is associated with a positive impact on quality of life compared with dimethyl fumarate: Results from the randomized, double-blind, phase III EVOLVE-MS-2 study
BACKGROUND: Diroximel fumarate (DRF) is a novel oral fumarate approved for relapsing forms of multiple sclerosis (MS). DRF demonstrated significantly improved gastrointestinal (GI) tolerability
METHODS: A
RESULTS: In total, 504 patients (DRF,
CONCLUSIONS: The improved GI tolerability with DRF translated into clinically meaningful benefits to QoL, as patients experienced less impact on daily life and work and required less concomitant symptomatic medication use.

Structural changes in gill DNA reveal the effects of contaminants on Puget Sound fish.
Structural differences were identified in gill DNA from two groups of English sole collected from Puget Sound, Washington, in October 2000. One group was from the industrialized Duwamish River (DR) in Seattle and the other from relatively clean Quartermaster Harbor (QMH). Chemical markers of sediment contamination [e.g., polynuclear aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs)] established that the DR was substantially more contaminated than QMH. The levels of these chemicals in the sediments of both sites were consistent with levels of cytochrome P450 1A (CYP1A) expression in the gills of English sole from the same sites. Structural differences in gill DNA between the groups were evinced via statistical models of Fourier transform-infrared (FT-IR) spectra. Marked structural damage was found in the gill DNA of the DR fish as reflected in differences in base functional groups (e.g., C-O and NH2) and conformational properties (e.g., arising from perturbations in vertical base stacking interactions). These DNA differences were used to discriminate between the two fish groups through principal components analysis of mean FT-IR spectra. In addition, logistic regression analysis allowed for the development of a "DNA damage index" to assess the effects of contaminants on the gill. The evidence implies that environmental chemicals contribute to the DNA changes in the gill. The damaged DNA is a promising marker for identifying, through gill biopsies, contaminant effects on fish

THE TREND TOWARDS IMPLEMENTING THE PRECAUTIONARY PRINCIPLE IN US REGULATION OF NANOMATERIALS
The precautionary principle provides a framework for regulating emerging technologies in general and nanomaterials in particular. It counsels action in the presence of uncertainties about risk instead of assuming that nanomaterials are safe unless proven hazardous. Nanomaterials are regulated under different statutory programs depending on whether they are drugs, pesticides or other commercial chemicals. Recent developments in the regulation of nanomaterials that are not drugs or pesticides have demonstrated a trend towards application of the precautionary principle. This is a paradigm shift away from the requirement built into past interpretations of the Toxic Substances Control Act (“TSCA”) that manufacturing, processing and use of chemical substances cannot be restricted unless the regulatory authority proves an unreasonable risk. This same paradigm shift is incorporated into recent legislative proposals to amend TSCA
Outcomes of the roll-in cohort of the Amulet IDE trial of left atrial appendage occlusion.
Background
Left atrial appendage (LAA) occlusion is an alternative therapy to oral anticoagulants to reduce stroke risk in patients with nonvalvular atrial fibrillation (NVAF). The Amulet IDE trial compared the Amplatzer™ Amulet™ occluder (Abbott) with the Watchman™ 2.5 device (Boston Scientific) for LAA occlusion in patients with NVAF.
Objective
The purpose of this study was to describe outcomes of the Amulet IDE trial roll-in cohort.
Methods
At US sites up to 3 patients per implanter could be implanted with the Amulet occluder in the roll-in phase. The primary Endpoints in the Amulet IDE trial included safety (composite of procedure-related complications, all-cause death, or major bleeding at 12 months), effectiveness (composite of ischemic stroke or systemic embolism at 18 months), and rate of LAA occlusion at 45 days.
Results
A total of 201 roll-in patients were enrolled. Device success occurred in 99% of patients, and device closure (residual jet ≤5 mm) was observed in 98.9% of patients at 45 days. The safety endpoint rate was numerically higher (worse) in the roll-in cohort compared to the randomized Amulet occluder cohort (18.4% vs 14.5%). Six patients (3.1%) experienced an ischemic stroke and 0 patients with a systemic embolism within 18 months, which was similar to the primary effectiveness endpoint rate in the randomized Amulet occluder cohort (2.8%).
Conclusions
Despite lack of experience of the operators with the Amulet occluder in the roll-in phase, device implant success was high, a high rate of device closure was achieved, and low stroke rates were observed in patients with NVAF
