“My Uncle's Cousin's Great-Grandma Were a Cherokee” and I am Descended from an Ashanti King: The American Blood Idiom in the Simple Stories
Authors: Hawkes DeLisa D. 
Published: March 2021

Abstract
Langston Hughes satirizes America's obsession with so-called “racial purity” in his stories featuring Jesse B. Semple to shed light upon internalized racism and white American attempts to erase US histories that complicate the standardized black-white color line. In his poem “The Negro Speaks of Rivers” (1920), the speaker challenges a singular view of the many Black histories that exist through the metaphor of rivers. In his Simple stories, Hughes's character Jesse B. Semple reflects on American Blackness and blood stereotypes that impact racial identity formation and community building. By invoking the “Indian grandmother” and royal African ancestor tropes, Hughes complicates those compartmentalized identities and US histories implied via the American blood idiom to denote associations with enslavement that bolster notions of intraracial difference and white supremacist ideology. Hughes's Simple stories culminate his trajectory in establishing African American pride in African ancestry and an anticolonial rejection of racial purity as a legal and social principle that contributes to monolithic conceptions of American Blackness.
Heavy Rotation—The DJ as Pedagogue: Jazz, Funk, and Teaching Langston Hughes's Poetry
Authors: Brown F. Douglas 
Published: March 2021

Abstract
This article seeks to give a pedagogical approach to Langston Hughes most anthologized poems, “A Negro Speaks of Rivers” and “Harlem.” These poems, like any good vinyl album, deserve their heavy rotation. However, we (the audience or readers) need to fine- (or refine-) tune our listening to hear what these poems have been delivering since their original publications. Using the work of Beyoncé and her sister Solange, this article, part personal journey, part pedagogical framework, offers a contemporary listening approach to help nascent listeners/readers of Hughes drop the needle on his work over and over.

Introdução;
A perda de massa óssea gradual origina osteopenia e sua evolução leva a osteoporose. A mesma é caracterizada por diminuição da massa óssea e deterioração da microarquitetura do tecido ósseo, aumento da fragilidade óssea e da susceptibilidade à fraturas. O objetivo deste artigo foi avaliar as diferenças entre as apresentações de cálcio disponíveis comercialmente quanto a sua eficácia, segurança e custos.
Metodologia;
Foi realizada uma revisão sistemática, utilizando as palavras-chave: “calcium”, “osteoporosis”, “doses”, “treatment”, “randomised”, “controlled” e “meta-analysis”. A seleção das publicações foi feita a partir de critérios de inclusão e exclusão.
Resultados13;
Ao total 2902 artigos relevantes foram identificados. Destes, 11 preencheram os critérios de seleção e foram incluídos neste estudo. Entre os sais de cálcio, encontra-se o citrato, carbonato, fluoreto, folinato, fosfato, e de ostras, e também são usados os bifosfonados, e cálcio associado a vitamina D e magnésio.
Conclusão13;
O uso do cálcio apresenta muitos benefícios na prevenção e tratamento da osteoporose, especialmente ao ser associado ao magnésio e vitamina D. O citrato de cálcio mostrou-se como a melhor opção de compra, visto que pode ser usado por idosos com problemas renais e também por pacientes que utilizam antiácidos, mostrando uma absorção e biodisponibilidade superior ao carbonato, sendo a escolha com o menor preço encontrado.

De WHOA en het contractenrecht
De Wet homologatie onderhands akkoord (WHOA) die per 1 januari 2020 in werking is getreden, kan grote implicaties hebben op gesloten contracten. De WHOA introduceert een uniek fenomeen in het Nederlands vermogensrecht: in een situatie buiten faillissement kunnen contractuele aanspraken worden gewijzigd ook als de wederpartij daar zelf niet mee instemt. Clausules die inroepbaar zijn bij initiatie van een schuldeisersakkoord onder de WHOA worden krachteloos. In dit artikel gaat de auteur per soort contract na wat de betekenis van de WHOA is voor dergelijke contractuele relaties en wat de mogelijkheden en de zin ervan zijn om de initiatie van een schuldeisersakkoord onder de WHOA in contracten op te nemen als grond voor beëindiging of om die aan goedkeuring van aandeelhouders te onderwerpen.

A Tale in Three Parts: The Success of California’s Life Science Clusters
Authors: Panetta Joe 
Published: March 2021

With the seventh largest GDP in the world, California has the economic heft of a country. One of the largest drivers of economic growth in California is the life science industry. In fact, it is a cornerstone of California’s innovation ecosystem, and is characterized by three distinct geographical clusters. There’s San Diego’s entrepreneurial energy, Los Angeles’ emerging incubators and the Bay Area’s unique tech influence. All of these clusters drive growth and distinct opportunities for institutes, universities, businesses and entrepreneurs.
This article focuses on: how did California become a life science powerhouse, and what do each of these regions have to offer to the industry?
Orthogonal Town Planning in Antiquity
Authors: Castagnoli Ferdinando 
Published: March 2021

The decisiveness of the right angle, which is uncommon in nature, would seem to exercise an irresistible appeal to the human mind, for it permeates man's art, artifacts, and architecture. That it should also appear as a basic organizational element in town plans over many centuries and in many cultures only confirms this appeal. The present work examines Greek, Etruscan, Italic, Hellenistic, and Roman cities that were based on orthogonal or grid plans – those characterized by streets intersecting at right angles to form blocks of regular size and spacing. Some of these have only recently been uncovered.
The author suggests that the implementation of these plans may have constituted the first exercise in master planning for the future extension and development of cities. These goals doubtless varied in ancient times from the tyrannical – suggesting an authoritarian control with the power to order a population into a strict grid pattern – to the egalitarian – implicit in the essential uniformity and equality of the blocks regardless of location.
In Roman times the orthogonal plan was to evolve into a quadrant system in which two broad streets at right angles served as the defining axes of the town, meeting to produce a formal central space, the “origin” of the coordinated city. These plans are discussed in the book, but the major emphasis is on “Hippodamean” layouts, in which a few – usually three or four – main parallel roads are intersected at right angles by numerous narrow streets to form long, narrow blocks.
Hippodamean plans are named for Hippodamus of Miletus, a Greek of the fifth century B. C. Although in antiquity Hippodamus was believed to have devised this scheme, the author points out that such plans antedate Hippodamus by an extensive period and that his role was one of refining and further systematizing the plan. His chief contribution appears to be the application of his insight into political organization and social behavior to town planning.
Indeed, Hippodamean plans go back at least to the seventh century B.C. in Greece, and rectangular elements basic to such plans have been found not only throughout the Mediterranean region but in Aztec, Indian, and Chinese cultures as well.
A number of aerial photographs are juxtaposed with detailed plans prepared by archaeologists and provide a fascinating insight into the solutions that Hippodamus and other planners evolved in the process of adjusting the needs of urban settlements to the exigencies of the terrain.
Good Corporate Governance, Capital Adequacy, Financing Risk, Profitability and Islamic Social Reporting (ISR) of Sharia Commercial Banks in Indonesia
Authors: Wijaya Dwi Indriani Fidiastutik , Sulistyo Agung Budi , Roziq Ahmad 
Published: March 2021

Aims: To empirically evaluate Sharia commercial banks in Indonesia for good corporate governance, capital adequacy, financing risk, profitability, and Islamic Social Reporting (ISR).
Study Design: Explanatory research with a quantitative approach and using secondary data.
Place and Duration of Study: Sharia commercial banks registered with the Financial Services Authority in the period 2015-2019.
Methodology: The sample selection used a purposive sampling technique and resulted in 7 Sharia commercial banks. Data analyzed using path analysis with SmartPLS 3.0. The analysis only uses the inner model evaluation because each variable in this study only uses one proxy or one indicator.
Results: Good corporate governance and capital adequacy affects financing risk, good corporate governance, capital adequacy, and financing risk affects profitability, financing risk affects Islamic Social Reporting (ISR), while good corporate governance, capital adequacy, and profitability do not affect Islamic Social Reporting (ISR).
Conclusions: Management should be able to create good corporate governance, manage capital adequacy to mitigate financing risk so that it can generate optimal profits for conducting sharia-based social activities and express it using the Islamic Social Reporting (ISR) as business transparency for stakeholders, thus increasing stakeholder confidence in the existence of Islamic commercial banks.

Aims: This study set out to describe the profile of adolescents admitted unto an inpatient unit in Nigeria and their evaluation of the service.
Study Design: This was a retrospective cohort study.
Place and duration of study: Department of Child and Adolescent Psychiatry, University College Hospital Ibadan, Nigeria between January 2016 and February 2020.
Methodology: Patient notes and discharge summaries were used to collect the demographic characteristics of adolescents and their families, diagnoses and treatments provided during the hospital stay. A feedback form was used to evaluate different aspects of the service. Data were analysed using descriptive statistics, and thematic analysis for open ended responses.
Results: There were slightly more females (56.4%) than males (43.6%)admitted during the period of study and their mean age was 18.2 years (SD =3.0). The most common psychiatry diagnosis was psychotic disorders (48.9%) followed by mood disorders (38.3%). Almost half (48.6%) had 2 or more psychiatric diagnosis. Second generation antipsychotics were the most frequently used medications by the participants (76.6%). Median length of stay on the unit was 2.5 weeks (IQR = 2.6). Themes which emerged from patients’ experiences on the ward were reductions in feelings of isolation, changes in mental health perceptions and self – discovery. Strengths of the unit included staff responsiveness and team work. Weaknesses of the unit cited were the poor physical environment, and inflexible routines. Suggestions on how to improve the unit included increasing recreational and physical activities and staff re - training. Parents/guardians also wanted more support for themselves, and peer support for their children.
Conclusions: Majority of patients admitted onto this unit were older adolescents with psychotic and mood disorders. They and their parents/guardians were generally satisfied with the treatment milieu of the unit, and gave recommendations for further improvement of services on the unit.
Retracted: The circadian rhythm regulator RpaA modulates photosynthetic electron transport and alters the preferable temperature range for growth in a cyanobacterium

Published: March 2021

Cyanobacterial strains can grow within a specific temperature range that approximately corresponds to their natural habitat. However, how the preferable temperature range for growth (PTRG) is determined at the molecular level remains unclear. In this study, we detected a PTRG upshift in a mutant strain of Synechococcus elongatus PCC 7942 lacking the circadian rhythm regulator RpaA. Subsequent analyses revealed that RpaA decreases the electron transport from photosystem I to NADPH. The change in electron transport likely inhibits H2O2 generation under high‐temperature conditions and contributes to the observed PTRG upshift in rpaA‐deficient cells. The importance of the effects of the circadian rhythm regulator on the PTRG is discussed.
Enhanced binding of the N501Y‐mutated SARS‐CoV‐2 spike protein to the human ACE2 receptor: insights from molecular dynamics simulations
Authors: Luan Binquan , Wang Haoran , Huynh Tien 
Published: March 2021

Recently, severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) variants (B.1.1.7 and B.1351) have emerged harbouring mutations that make them highly contagious. The N501Y mutation within the receptor‐binding domain (RBD) of the spike protein of these SARS‐CoV‐2 variants may enhance binding to the human angiotensin‐converting enzyme 2 (hACE2). However, no molecular explanation for such an enhanced affinity has so far been provided. Here, using all‐atom molecular dynamics simulations, we show that Y501 in the mutated RBD can be well‐coordinated by Y41 and K353 in hACE2 through hydrophobic interactions, which may increase the overall binding affinity of the RBD for hACE2 by approximately 0.81 kcal·mol−1. The binding dynamics revealed in our study may provide a working model to facilitate the design of more effective antibodies.
Internalizing and externalizing symptoms and aggression and violence in men and women
Authors: Mendez Beatriz , Bozzay Melanie , Verona Edelyn 
Published: March 2021

AbstractLiterature linking aggressive behavior across internalizing and externalizing disorders support the co‐occurrence of aggression and various mental health diagnoses. However, research has yet to examine relationships between aggression and dimensional psychopathology models that cut across diagnostic boundaries (e.g., internalizing, externalizing composites) and capture shared liability across common disorders. The role of gender has also been largely ignored in prior work, despite evidence that men and women manifest psychopathology differently. The present study examined cross‐sectional and longitudinal relationships between psychopathology composites (i.e., Internalizing, Externalizing) and different manifestations of physical aggression (i.e., aggressive traits, general violence, physical intimate partner violence, and self‐directed aggression), as well as moderation by gender. Internalizing (INT) and Externalizing (EXT) lifetime symptoms and various physically aggressive behaviors were assessed at baseline and at 6 months and 1 year follow up in a sample of 319 adults with violence and/or substance use histories. Cross‐sectional results showed that INT was associated with all forms of aggression, and women showed stronger relationships between INT and both physical intimate partner violence (IPV) and self‐directed aggression. EXT was specifically linked to general violence, and a stronger relationship between EXT and self‐directed aggression emerged in men compared to women. Longitudinal relationships were mostly small and nonsignificant. Results support the co‐occurrence of aggression with distinct forms of psychopathology, as well as gender‐dependent relationships, but do not support the predictive validity of symptom composites in aggression risk. Findings implicate the need for aggression interventions tailored within gender.
One‐Pot Synthesis of 3‐Halo‐2‐organochalcogenylbenzo[b]chalcogenophenes from 1‐(2,2‐Dibromovinyl)‐2‐organochalcogenylbenzenes

Published: March 2021

AbstractA transition‐metal‐free one‐pot synthesis of 3‐halo‐2‐organochalcogenylbenzo[b]chalcogenophenes has been developed using 1‐(2‐organochalcogenylethynyl)‐2‐butylchalcogenylbenzenes generated in situ from 1‐(2,2‐dibromovinyl)‐2‐organochalcogenylbenzenes and diorganoyl dichalcogenides. By this method, several 2,3‐disubstituted benzo[b]chalcogenophenes were prepared in yields of 48–93%. The mechanistic investigation suggests that the formation of chalcogenoacetylenes containing an adjacent chalcogen atom in the first step of this one‐pot procedure involves acetylide anions formed from 1‐(2,2‐dibromovinyl)‐2‐organochalcogenylbenzenes and mild bases.magnified image

AbstractDespite differences between the cover crop growth and decomposition phases, few greenhouse gas (GHG) studies have separated these phases from each other. This study's hypothesis was that a living cover crop reduces soil inorganic N concentrations and soil water, thereby reducing N2O emissions. We quantified the effects of a fall‐planted living cereal rye (Secale cereale L.) cover crop (2017, 2018, 2019) on the following spring's soil temperature, soil water, water‐filled porosity (WFP), inorganic N, and GHG (N2O‐N and CO2–C) emissions and compared these measurements to bare soil. The experimental design was a randomized complete block, where years were treated as blocks. Rye was fall planted in 2017, 2018, and 2019, but mostly emerged the following spring. The GHG emissions were near‐continuously measured from early spring through June. Rye biomass was 1,049, 428, and 2,647 kg ha–1 in 2018, 2019, and 2020, respectively. Compared to the bare soil, rye reduced WFP in the surface 5 cm by 29, 15, and 26% in 2018, 2019, and 2020 and reduced soil NO3–N in surface 30 cm by 53% in 2019 (p = .04) and 65% in 2020 (p = .07), respectively. Rye changed the N2O and CO2 frequency emission signatures. It also reduced N2O emissions by 66% but did not influence CO2–C emissions during the period prior to corn (Zea mays L.) emergence (VE). After VE, rye and bare soils N2O emissions were similar. These results suggest that nitrous oxide (N2O‐N) sampling protocols must account for early season impacts of the living cover.
