In the United States, schools closed in March 2020 due to COVID-19 and have begun reopening as of August 2020, despite continuing transmission of SARS-CoV-2. To determine the impact of school reopening with varying levels of operating capacity and face-mask adherence, we used an agent-based model calibrated to and validated against multiple data types from the state of Indiana, USA. In our model, transmission can occur in schools, workplaces, community settings, and households, all of which are structured in a realistic way according to state geography and demography. Using this model, we quantified the burden of COVID-19 on K-12 students, teachers, their families, and the general population under alternative scenarios about school reopening. In our primary analysis, we considered three levels of school operating capacity (50%, 75%, and 100%) and three assumptions about face-mask adherence in schools (50%, 75%, and 100%). Under a scenario in which schools operate remotely, we projected 45,579 (95% CrI: 14,109-132,546) infections and 790 (95% CrI: 176-1680) deaths between August 24 and December 31. Reopening at 100% capacity with 50% face-mask adherence in schools resulted in a proportional increase of 42.9 (95% CrI: 41.3-44.3) times that number of infections and 9.2 (95% CrI: 8.9-9.5) times that number of deaths. In contrast, operating at 50% capacity with 100% face-mask adherence resulted in only an 11% (95% CrI: 5%-18%) increase in the number of infections compared to the scenario in which schools operate remotely. We conclude that reduced capacity and high face-mask adherence in schools substantially reduce the burden of COVID-19, both among those with direct ties to schools and across the state. As Indiana and other states proceed with school reopening, our results illustrate quantitatively the benefits of safety measures that schools are undertaking, underscoring their value for both schools and their communities.

AbstractBackgroundThe efficacy of bevacizumab (BEV) in elderly patients with glioblastoma remains unclear. We evaluated the effect of BEV on survival in this patient population using the Survival, Epidemiology, and End Results (SEER)-Medicare database.MethodsThis retrospective, cohort study analyzed SEER-Medicare data for patients (aged ≥66 years) diagnosed with glioblastoma from 2006 to 2011. Two cohorts were constructed: one comprised patients who had received BEV (BEV cohort); the other comprised patients who had received any anticancer treatment other than BEV (NBEV cohort). The primary analysis used a multivariate Cox proportional hazards model to compare overall survival in the BEV and NBEV cohorts with initiation of BEV as a time-dependent variable, adjusting for potential confounders (age, gender, Charlson comorbidity index, region, race, radiotherapy after initial surgery, and diagnosis of coronary artery disease). Sensitivity analyses were conducted using landmark survival, propensity score modeling, and the impact of poor Karnofsky Performance Status.ResultsWe identified 2603 patients (BEV, n = 597; NBEV, n = 2006). In the BEV cohort, most patients were Caucasian males and were younger with fewer comorbidities and more initial resections. In the primary analysis, the BEV cohort showed a lower risk of death compared with the NBEV cohort (hazard ratio, 0.80; 95% confidence interval, 0.72–0.89; P < .01). The survival benefit of BEV appeared independent of the number of temozolomide cycles or frontline treatment with radiotherapy and temozolomide.ConclusionBEV exposure was associated with a lower risk of death, providing evidence that there might be a potential benefit of BEV in elderly patients with glioblastoma.

As part of its “War on Terror”, the United States (US) provided immense sums of money and advanced equipment to Afghan warlords in order to defeat and dismantle the Taliban and al-Qaeda in Afghanistan. Nearly two decades after the 2001 US-led intervention in Afghanistan that toppled the Taliban regime, the US continues supporting the warlords in various ways. As the intervention was also aimed at establishing a functioning state and reconstruction of the war-torn country, the US needed the support of local warlords to achieve its goals. However, over time, warlords and warlordism became a major challenge to the postTaliban state-building project and in many ways undermined the overall security and the state monopoly on violence. These warlords, who had been mostly expelled and defeated by the Taliban regime, returned under the aegis of the B52 bombers, recaptured parts of the country and reestablished their fiefdoms with US support and resources. They not only resist giving up the power and prestige they have accumulated over the past few years, but also hamper the effort to improve governance and enact necessary reforms in the country. In addition, many of them run their private militias and have been accused of serious human rights abuses as well as drug trafficking, arms smuggling, illegal mining and extortion in the areas under their control or influence. In many ways, they challenge the government authority and have become a major hurdle to the country’s emerging from lawlessness and anarchy. This paper explores the emergence and reemergence of warlords in Afghanistan as well as the evolution of chaos and anarchy in the country, especially after the US-led intervention of late 2001. It also analyzes the impact of the post-9/11 US support to Afghan warlords and its negative consequences for the overall stability and the US-led state-building process in Afghanistan.

The focus of this article is on the evaluation and outcomes of a professional learning opportunity that focused on 13 current K–12 public school science educators in the United States. This teacher training concentrated on sustainability education that utilized marine sciences as a unifying concept. Findings from this training helped to identify models within teacher professional development in marine science that lead to comprehensive adoption of presented curricula. Four established models/frameworks of professional development were identified and their subsequent classroom implementation was evaluated. Results include adoption rates of the various session materials, the impact and effect size of differing variables (such as deliverables or standards alignment) among the four models and their frameworks and changes in perceptions towards sustainability initiatives. These outcomes underscore several methods and strategies for successful science teacher professional development implementation in regard to marine sciences.

The continued spread of COVID-19 suggests a significant possibility of reimposing the lockdowns and stricter social distancing similar to the early phase of pandemic control. We present a dynamic model to quantify the impact of isolation for the contagion curves. The model is calibrated to the COVID-19 outbreak in Spain to study the effects of the isolation enforcement following the declaration of the state of alarm (14 March 2020). The simulations indicate that both the timing and the intensity of the isolation enforcement are crucial for the COVID-19 spread. For example, a 4-day earlier intervention for social distancing would have reduced the number of COVID-19 infected people by 67%. The model also informs us that the isolation enforcement does not delay the peak day of the epidemic but slows down its end. When relaxing social distancing, a reduction of the contagion probability (with the generalization of preventive actions, such as face mask wearing and hands sanitizing) is needed to overcome the effect of a rise in the number of interpersonal encounters. We report a threshold level for the contagion pace to avoid a second COVID-19 outbreak in Spain.

The authors analyze the impact of migration from Venezuela on the domestic policy of the United States. According to the data for 2017, more than 11 percent of immigrants to the United States from South America are Venezuelans, and the same figure for 2016 was close to 9 percent, which indicates a fairly sharp increase in the number of refugees. An active influx of Venezuelans may be one of the key factors in the future US 2020 presidential elections. The largest diaspora of Venezuelans in the United States lives in Florida, which will be one of the key states in the future presidential election campaign. In connection with the potential loss of Republican’s positions in such an important region as Florida, it is necessary for the administration of Donald Trump to reconsider its policy in the state. In addition, representatives of the Democratic party are greatly interested in increasing influence in the state. Thus, the authors conclude that the administration of Donald Trump generally benefits from the crisis in Venezuela, as it will help to carry out a number of domestic political reforms aimed at economic protectionism and tackling of immigration.

BACKGROUND As the COVID-19 pandemic continues to affect life in the United States, the important role of nonpharmaceutical preventive behaviors (such as wearing a face mask) in reducing the risk of infection has become clear. During the pandemic, researchers have observed the rapid proliferation of misinformed or inconsistent narratives about COVID-19. There is growing evidence that such misinformed narratives are associated with various forms of undesirable behavior (eg, burning down cell towers). Furthermore, individuals’ adherence to recommended COVID-19 preventive guidelines has been inconsistent, and such mandates have engendered opposition and controversy. Recent research suggests the possibility that trust in science and scientists may be an important thread to weave throughout these seemingly disparate components of the modern public health landscape. Thus, this paper describes the protocol for a randomized trial of a brief, digital intervention designed to increase trust in science. OBJECTIVE The objective of this study is to examine whether exposure to a curated infographic can increase trust in science, reduce the believability of misinformed narratives, and increase the likelihood to engage in preventive behaviors. METHODS This is a randomized, placebo-controlled, superiority trial comprising 2 parallel groups. A sample of 1000 adults aged ≥18 years who are representative of the population of the United States by gender, race and ethnicity, and age will be randomly assigned (via a 1:1 allocation) to an intervention or a placebo-control arm. The intervention will be a digital infographic with content based on principles of trust in science, developed by a health communications expert. The intervention will then be both pretested and pilot-tested to determine its viability. Study outcomes will include trust in science, a COVID-19 narrative belief latent profile membership, and the likelihood to engage in preventive behaviors, which will be controlled by 8 theoretically selected covariates. RESULTS This study was funded in August 2020, approved by the Indiana University Institutional Review Board on September 15, 2020, and prospectively registered with ClinicalTrials.gov. CONCLUSIONS COVID-19 misinformation prophylaxis is crucial. This proposed experiment investigates the impact of a brief yet actionable intervention that can be easily disseminated to increase individuals’ trust in science, with the intention of affecting misinformation believability and, consequently, preventive behavioral intentions.

These four nations showcase the state of Islamism as a political force in the Middle East. Because of differing political circumstances in each state, the impact and viability of following Muslim law varies. In order to best explain why this is so, we will explore the political background of each nation, as well as discuss the current political climates of the countries in question. Finally, we will postulate as to what type of impact the ascension of an Islamic government will have on relations with the Western world, whether it be European nations, as is the case with Turkey, or the United States, as with Kuwait, Jordan and Egypt. The implications of this possibility are enormous; therefore, we feel that the importance of understanding the region cannot be overstated.

Although widely seen as unruly and predatory, prison gangs operate as quasi-governments in many American correctional facilities. Inmate groups enforce property rights, regulate illicit markets, and promote cooperation when the state is unable or unwilling to act. Prison gangs are relatively new to the United States, and are best understood as unintended consequences of recent shifts in inmate demographics and the gradual erosion of the convict code. The impact of prison gangs on street-level criminal activities and directions for further research are also discussed.

Abstract Horizontal drilling together with hydraulic fracturing has become a very effective mechanism for the extraction of natural gas in several shale plays in the United States. Efficient horizontal drilling, however, generally requires operating in a “unit,” across the property of numerous landowners. If a landowner, however, is unwilling to allow drilling beneath their property, the result can be harmful to both the producing company and other landowners in the unit. To address this problem, most major oil and nature gas states, except for Pennsylvania, have unitization statutes. We examine the impact of such laws by looking at the recent Emersyn matter from the state of Ohio. We estimate that the unitization ordered by the State of Ohio greatly increased the potential recoverable product from the proposed unit. Just as importantly, it more than proportionally increased the profits to the producer and royalty owners. Our results also show that the breakeven production price is very sensitive to whether forced unitization is available to the producer. At least three policy issues arise from this analysis. First, the rationale for unitization is not clear in all circumstances. In the Emersyn matter, the State of Ohio required access to property rights, even though not allowing such access would not have “stranded” any other landowners, and where the party in question was a sophisticated producer, rather than a landowner. Second, there appears to be no guidance for setting reimbursements to property owners who are forced to allow producers access to their property. Third, it is not clear the extent to which the state should take the producers' plans as given, rather than inquire about options to unitization.
