There’s more to us than this: A qualitative study of Black young adults’ perceptions of media portrayals of HIV
The extent to which the targeted group attends to and is engaged by HIV/STI prevention messages is one component of effective health communication. Through an empirical examination of the cumulative perceptions of HIV/STI prevention media messages targeted to Black youth and young adults, this qualitative study privileges the voices of Black/ African American young adults as a group that is frequently targeted in HIV prevention campaigns. Semi-structured interviews with 23 Black/African American young adults yielded key themes that suggest barriers to effective health communication. Traditionally, health promotion has advocated for targeted messages as a means to increase risk perception and promote behavior change. For some study participants, the unintended consequences of this approach with HIV prevention included a perception that cumulatively media messages (1) portrayed HIV as a “Black disease; (2) blamed Black people for the HIV epidemic; and (3) fostered negative judgments about Black people. Participants described mixed feelings because they perceived that the messages simultaneously increased awareness for HIV prevention in the Black community as well as perpetuated stigma of the Black community. The findings challenge existing notions about targeting health communication particularly when focusing on stigmatized illnesses
Furniture Stability: A Review of Data and Testing Results
This report by Kids In Danger (KID) and Shane's Foundation focuses on tip-overs of dressers and chests. ASTM International, which has developed thousands of voluntary industry consensus technical standards, has a standard in place to test furniture stability. However, furniture on the market is not required to conform, resulting in widespread non-compliance. Additionally, these standards are too lenient and require reform, as testing protocols have remained virtually unchanged for over a decade, despite continuing injuries and deaths. Units may pass the standard, but still present a significant risk. KID advocates for a two-pronged approach to decreasing tip-over incidents:Increasing consumer awareness of the danger of furniture tip-overs and knowledge of the actions needed to keep children safe, andImproving furniture stability by strengthening standards, making those standards mandatory and enforceable and promoting changes in furniture design.KID compiled data from incidents reported to the U.S. Consumer Product Safety Commission (CPSC) by various sources and from the National Electronic Injury Surveillance System (NEISS). These include reports from January 1, 2010 to October 14, 2015. Findings of the data analysis include:Two-year-olds are the age group most affected by tip-overs, especially in regard to fatal incidents.Children age 2 to 5 accounted for 77% of total incidents.The age range of children injured is wider than the age range of children killed by tip-overs.Fatalities accounted for 12% of total incidents.Head injuries (37%) were the most common category of injury.Almost all (98.7%) of head injuries are related to a television tipping over on a child.KID conducted performance tests on a sample of 19 dressers and chests. Testing was run at the UL Furniture Center of Excellence in Holland, Michigan. UL laboratory technicians followed a testing protocol developed by KID. The protocol included tests based on the current voluntary standard for furniture stability. KID added tests that, among other things, evaluated for tip-overs when more weight was added (simulating larger children), drawers were full of clothes, furniture was placed on carpeting as opposed to bare flooring, televisions were placed on top of the furniture, and additional drawers were opened simultaneous with weighting one drawer. These additional tests were intended to be more representative of real-world scenarios.Test results include:Only nine of the 19 units passed performance tests based on the current tip-over safety standard, ASTM F2057.Only two units passed all tests, including the additional testing protocols added by KID.The weight of a television or any type placed on top of the unit did not decrease the stability of furniture.Furniture placed on carpet is less stable than furniture placed on hard floors.Many units remained stable when more than 70 pounds was placed on an open drawer, while others tipped with less than half that weight

Imagining the “Day of Reckoning”: American Jewish Performance Activism during the Holocaust
Scholars of American Jewish history have long debated the complicity of the American Jewish community in the loss of six million Jewish lives in Europe during the Holocaust. After Hitler took power in 1933, American Jewish leaders took to the streets to protest the Nazi Party’s abuse of German Jews. Two central figures in this history are Reform Rabbi Stephen Wise and Revisionist Zionist Ben Hecht because of their wide-reaching protest movements that operated in competition with each other. Although the historiography presents Wise and Hecht\u27s inability to unite as the product of difference, my examination of their protest performances presents a novel picture of similarity. Despite their ideological antagonism, Wise and Hecht\u27s shared cultural identities, as both Americans and Jews, produced pageants with decidedly similar elements. The three productions studied here – The Case of Civilization Against Hitler (1934), Stop Hitler Now (1943), and We Will Never Die (1943) – were reflective of these identities. Appealing to their Americanness, they performed rituals of democratic justice. Appealing to their Jewishness, they presented Jewish prayer, iconography, and ritual related to divine justice. In highlighting the parallels in the performances, I read their actions as successful insofar as they appealed to a diverse American Jewish audience

A Markov Chain Monte Carlo approach for measurement of jet precession in radio-loud active galactic nuclei
© 2020 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society. All rights reserved.Jet precession can reveal the presence of binary systems of supermassive black holes. The ability to accurately measure the parameters of jet precession from radio-loud AGN is important for constraining the binary supermassive black hole population, which are expected as a result of hierarchical galaxy evolution. The age, morphology, and orientation along the line of sight of a given source often result in uncertainties regarding jet path. This paper presents a new approach for efficient determination of precession parameters using a 2D MCMC curve-fitting algorithm which provides us a full posterior probability distribution on the fitted parameters. Applying the method to Cygnus A, we find evidence for previous suggestions that the source is precessing. Interpreted in the context of binary black holes leads to a constraint of parsec scale and likely sub-parsec orbital separation for the putative supermassive binary.Peer reviewe
In Vitro Evaluation of Ethano-Botanically Important Plant Extracts against Early Blight Disease (Alternaria Solani ) of Tomato
The Tomato (Lycoperiscum esculantum) is a diploid species with 2n=24 chromosomes and belongs to the family Solanaceae. It is the world’s largest vegetable crop after potato. The area under tomato in India is about 4.97 lakh hectares with a production of about 86 lakh tons. Early blight is caused by the fungus Alternaria solani Sorauer. This disease in severe cases can lead to complete defoliation and is most damaging on tomato in regions with heavy rainfall, high humidity and fairly high temperatures (24oC-29oC). A. solani is characterized by septate beaked muriform conidia borne singly on simple conidiophore, In the present study Ten locally available plants which are ethano-botanically important are selected viz., Amaranthus caudatus, Anacardium occidentale, Azadirachta indica, Bambusa arundinacea , Capsicum annuum, Ecballium elaterium, Eucalyptus gobules, Ficus religiosa , Lantana camara and Morus alba aquoes and thier extracts were evaluated against A. solani by poison food technique. The results revealed that leaf and seed extracts of A.indica recorded maximum mycelial inhibition with 78.83% followed by L. camara with 59.9% and E. globules with 59.7% inhibition in mycelial growth and B. arundinacea exhibited least mycelial inhibition with 3.7%
Screening of Arbuscular Mycorrhizal Fungi for their Symbiotic Efficiency on Ocimum Sanctum L
Screening of four indigenous AM fungi for improvement of plant growth, biomass production and nutrient uptake was undertaken on Ocimum sanctum L. the results revealed that, plants inoculated with Rhizophagus fasciculatus was found to be the most significant. After 30 days increased shoot length, dry weight of root and shoot, mycorrhizal colonization and spore number were recorded. Plants inoculated with AM fungus R. fasciculatus showed significantly more number of flowers, compared to other AM fungi treated plants. The indigenous species, Rhizophagus fasciculatus was the best species among four species tested.Hence, it can be concluded that experimental plant showed varied response to different AM fungi and Rhizophagus fasciculatus confers maximum growth benefits compared to all other fungi used in this study
Instability of nonnegative solutions for a class of semilinear elliptic boundary value problems
AbstractWe consider the boundary value problem −Δu(x) = λf(u(x)), x ∈ Ω, Bu(x) = 0, x ∈ ∂Ω, where Ω is a bounded region in Rn with smooth boundary Bu(x) = αh(x)u + (1 − α)∂u∂n where α ∈ [0,1], h: ∂Ω → R+ with h = 1 when α = 1, λ > 0, f is a smooth function such that ƒ″(u) > 0 for u > 0, ƒ(u) < 0 for u ∈ (0,β) and ƒ(u) > 0 for u > β for some β > 0. We provide a simple proof to establish that every non-trivial nonnegative solution is unstable
Mewujudkan Sistem Peradilan Pidana Berwibawa Di Indonesia
The authoritative criminal justice system in Indonesia should be realized in order to get trust and respect from the society. The basic norm order which is embraced in the legal principles is the manifestation of the supreme bases, that is the Grand norm of Pancasila. It should become the legal spirit in the legal validity and reality. The authoritative criminal justice system shall occur when the criminal justice system holds high the criminal legal principles as the meta norm and the attitude guidance. The accountability aspect for criminal justice and its implication towards controllability and responsiveness of institute is very significant in the development of the authoritative justice system. Therefore, it requires a system approach to promote structural, substantial, and cultural synchronizations for the sake of the establishment of legal council and institution in the criminal justice system
