To highlight the impact of the two-dimensionality of the synthesized polyglycerol sulfate nanosheets at nanobiointerfaces, their efficiency with respect to herpes simplex virus type 1 and severe acute respiratory syndrome corona virus 2 inhibition is compared to their 3D nanogel analogs. Four times stronger in virus inhibition suggests that 2D polyglycerols are superior to their current 3D counterparts.The world is reeling in the midst of the novel coronavirus pandemic with fear of rising toll due to the deadly virus. Decision making during a pandemic outbreak has numerous challenges. Covid19 has become a challenging problem for organizations, countries and the world at large. It is even more complicated when governments and medical care communities are changing their priorities based on the growing challenges and level of effectiveness of measures taken in other countries. In this study, a potential application of a well-known MCDM method called the Group Best-Worst Method is presented to overcome such challenges and draw the strategies to handle COVID19 outbreak. The methodology is applied to rank the 10 identified strategies based on their relative importance provided by multiple groups of stakeholder. These strategies focus on social distancing, medical care, essential commodities, financial support to poor people, public awareness, overall impact of COVID19, digital surveillance of infected or doubtful people, maintaining the economy of the country, and an effect on industries. Furthermore, the local and global weights along with ranking order of strategies are obtained. A sensitivity analysis has also been done to show the change in global weights and ranking order of strategies.This article examines the history of racism in the American presidency and the implications that it has had for Black residents of this country. The paper begins with a discussion of President Trump's racist rhetoric towards Blacks but notes that a history of racism is woven into the US presidency. We employ critical race theory as a theoretical framework to demonstrate why institutional racism has always been pervasive in the American presidency. Using a case study analysis, the authors conduct a comparative study of the history of racism of American presidents with the presidency of former president Donald J. Trump. The authors conclude that for most of the nation's history, racism and indifference to African Americans permeated the US presidency. It has only been since the advent of the second half of the twentieth century, for the most part, that there have been meaningful efforts by US presidents to address the concerns of African Americans.Deteriorating mental health among university students during the COVID-19 pandemic is a serious worldwide public health concern. This study aims to examine the linkage between social media addiction and mental health of university students in Indonesia and to address whether family relationship and religiosity may mitigate the harmful effects of social media on the mental health of students at this time. We collected data from 709 students at universities across the country between June 3 and June 20, 2020. Mental health was measured using 10 items validated by the Center for Epidemiological Studies-Depression (CES-D) scale. We found that students with higher social media addiction scores had a greater likelihood of experiencing mild depression (OR 1.07, CI 1.02-1.12). Students who had good relationships with their parents and were more religious showed better mental health than those who had poor relationships with their parents and were less religious. This study suggests the need to mitigate university students' mental health risks through reducing social media addiction while encouraging family relationships and religiosity during the pandemic.The COVID-19 public health pandemic has seen governments spend trillions of dollars to limit the spread of the COVID-19 virus as well as to soften the economic blow from the shutting down of national economies. Subsequent budget shortfalls raise the question of how governments will pay for the direct and indirect costs associated with the COVID-19 pandemic. In this article, we study the public's willingness to contribute through paying a new tax, with a focus on Canada. We find that both generalized social and political trust are associated with a greater willingness to support a COVID-related tax and that generalized social trust, in particular, attenuates the negative effect of an experimentally manipulated, specified level of tax burden on policy support. These findings entail important implications for the public opinion and tax policies literature, as well as for policy makers. Gainous, Jason, Stephen C. Craig, and Michael D. Martinez. 2008. "Social Welfare Attitudes and Ambivalence about the Role of Gos, 1980-2005." Politics & Policy 41 (6) 947-984. https//doi.org/10.1111/polp.12053. The onset of extreme social distancing measures is expected to have a dramatic impact on crime. Here, we examine the impact of mandated, city-wide social distancing orders aimed at limiting the spread of COVID-19 on gang-related crime in Los Angeles. We hypothesize that the unique subcultural processes surrounding gangs may supersede calls to shelter in place and allow gang-related crime to persist. If the normal guardianship of people and property is also disrupted by social distancing, then we expect gang violence to increase. Using autoregressive time series models, we show that gang-related crime remained stable and crime hot spots largely stationary following the onset of shelter in place. In responding to disruptions to social and economic life on the scale of the present pandemic, both police and civilian organizations need to anticipate continued demand, all while managing potential reductions to workforce. Police are faced with this challenge across a wide array of crime types. Civilian interventionists tasked with responding to gang-related crime need to be prepared for continued peacekeeping and violence interruption activities, but also an expansion of responsibilities to deal with "frontline" or "street-level" management of public health needs.
