Patterns of Genetic Diversity in Highly Invasive Species: Cogongrass \u3ci\u3e(Imperata cylindrica)\u3c/i\u3e Expansion in the Invaded Range of the Southern United States (US)

The spatial expansions of invasive organisms in the novel range are generally expected to follow an isolation-by-distance relationship (IBD) if the invasion is biologically driven; however, many invasions are facilitated anthropogenically. This research focused on the extant expansion patterns of cogongrass (Imperata cylindrica). Cogongrass is a widespread invasive species throughout the southern United States (US). Patterns of infestation vary among US states. Cogongrass is pyrogenic, and its invasion threatens softwood (Pinus spp.) plantations, a substantial economic market for this US region. Over 600 individuals were sampled from seven invaded US states, using amplified fragment length polymorphisms (AFLPs) to assess genetic diversity and population structure. We suspected that differences in historical management efforts among US states influenced differences in genetic diversity and structure. We detected two genetic lineages at the highest level of analysis. One genetic lineage was locally restricted, whereas the other was found throughout the study region. Admixed individuals were found in all US states and consistently co-occurred with the dominant lineage, suggesting that secondary contact and hybridization may have facilitated expansion. The widespread prevalence of only one of the two detected genetic lineages suggests a primary genetic lineage responsible for on-going population expansion in the US

Bridge Builders to Health Equity: The High School Community Health Worker Training Program

Background: During the summers of 2016- 2019, Morehouse School of Medicine (MSM) with the support of community partners, developed, piloted and implemented an innovative Community Health Worker Training Program for High School students (HSCHW). Training high school community health workers can impact health and social disparities in underserved populations and demonstrates pipeline of future workers in community health and other health careers. The program has achieved promising outcomes, and access to the program model has been requested many universities and community-based organizations. Method: The HSCHW training consists of summer classroom instruction, field instruction and monthly continuing education during the school year. The students are trained in CHW core competencies through a combination of online curriculum, interactive classroom experiences, and field activities provided by community partners, multidisciplinary MSM clinical instructors, and graduate student interns. Results: 77 high school students from metropolitan Atlanta High Schools and rural Columbus, GA have been trained as CHWs in the HSCHW program. Students are ages 15-18 and are rising sophomores to recent high school graduates. All participants (100%) were from economically disadvantaged communities. Sixteen school-based and community-based health improvement projects have been developed and implemented by teams of trained HSCHWs. Additionally, over 300 individuals (family and community members) received monthly health monitoring by trained HSCHWs. Conclusions: Overall, the HSCHW program models the engagement of community partners in translational educational initatives to support community transformation. It can be a giant leap toward improved population health and achieving health equity in underserved communities. It has had a tremendous impact on the youth themselves, their families, and the communities in which they live. In communities with disparate prevalence of chronic disease and unhealthy behaviors, early exposure may mitigate exacerbation or early onset of disease among the participants and their families. High School Community Health Workers are bridges to health equity

Has the regulation of non-GAAP disclosures influenced managers' use of aggressive earnings exclusions?

The frequency of non-GAAP (“pro forma”) reporting has continued to increase in the U.S. over the last decade despite preliminary evidence that regulatory intervention led to a decline in non-GAAP disclosures. In particular, the Sarbanes-Oxley Act of 2002 (SOX) and Regulation G (2003) impose strict requirements related to the reporting of non-GAAP numbers. More recently, the SEC has renewed its emphasis on non-GAAP reporting and declared it a “fraud risk factor.” Given the SEC’s renewed emphasis on non-GAAP disclosures, we explore the extent to which regulation has curbed potentially misleading disclosures by investigating two measures of aggressive non-GAAP reporting. Consistent with the intent of Congress and the SEC, we find some evidence that managers report adjusted earnings metrics more cautiously in the post-SOX regulatory environment. Specifically, the results suggest that firms reporting non-GAAP earnings in the post-SOX period are less likely to (1) exclude recurring items incremental to those excluded by analysts and (2) use non-GAAP exclusions to meet strategic earnings targets on a non-GAAP basis that they miss based on I/B/E/S actual earnings. However, we also find that some firms exclude specific recurring items aggressively. Overall, the results suggest that while regulation has generally reduced aggressive non-GAAP reporting, some firms continue to disclose non-GAAP earnings numbers that could be misleading in the post-SOX regulatory environment

Magnetorheological landing gear: 2. Validation using experimental data

Aircraft landing gears are subjected to a wide range of excitation conditions with conflicting damping requirements. A novel solution to this problem is to implement semi-active damping using magnetorheological (MR) fluids. In part 1 of this contribution, a methodology was developed that enables the geometry of a flow mode MR valve to be optimized within the constraints of an existing passive landing gear. The device was designed to be optimal in terms of its impact performance, which was demonstrated using numerical simulations of the complete landing gear system. To perform the simulations, assumptions were made regarding some of the parameters used in the MR shock strut model. In particular, the MR fluid's yield stress, viscosity, and bulk modulus properties were not known accurately. Therefore, the present contribution aims to validate these parameters experimentally, via the manufacture and testing of an MR shock strut. The gas exponent, which is used to model the shock strut's nonlinear stiffness, is also investigated. In general, it is shown that MR fluid property data at high shear rates are required in order to accurately predict performance prior to device manufacture. Furthermore, the study illustrates how fluid compressibility can have a significant influence on the device time constant, and hence on potential control strategies

Cage-induced stereotypic behaviour in laboratory mice covaries with nucleus accumbens FosB/ΔFosB expression.

Stereotypic behaviour (SB) occurs in certain human disorders (e.g. autism), and animals treated with stimulants or raised in impoverished conditions, including laboratory mice in standard cages. Dysfunctional cortico-basal ganglia pathways have been implicated in these examples, but for cage-induced forms of SB, the relative roles of ventral versus dorsal striatum had not been fully ascertained. Here, we used immunohistochemical staining of FosB and ΔFosB to assess long-term activation within the nucleus accumbens and caudate-putamen of C57BL/6 mice. Housed in typical laboratory cages, these mice spontaneously developed different degrees of route-tracing, bar-mouthing and other forms of SB (spending 0% to over 50% of their active time budgets in this behaviour). The most highly stereotypic mice showed the most elevated FosB/ΔFosB activity in the nucleus accumbens. No such patterns occurred in the caudate-putamen. The cage-induced SB common in standard-housed mice thus involves elevated activity within the ventral striatum, suggesting an aetiology closer to compulsive gambling, eating and drug-seeking than to classic amphetamine stereotypies and other behaviours induced by motor loop over-activation

Making the Case for Community Health Workers in Georgia

Background: Community Health Workers (CHW) can be an important and evidence-based response to reduce unnecessary morbidity and mortality in chronic diseases like asthma, heart disease, diabetes, cancers, HIV, and maternal/child health, and mental health. Georgia’s urban and rural diverse populations are at high risk from many of these conditions. Largely the outcomes in controlling these health issues are nonmedical and include social determinants of health, i.e., access to care, transportation, inadequate housing, and health literacy. CHWs can increase the capacity of individuals, families, and communities to improve their health. Historically, concerns of CHWs on healthcare teams to address these issues have centered on standardized training, credentialing, and challenges about the unique roles and responsibilities of CHWs. In this article, we discuss the evidence of effectiveness and return on investment as CHW interventions prove to reduce visits to the Emergency Departments and unnecessary hospitalizations from chronic diseases. They serve to connect social and medical resources and ensure patients to not fall through gaps, especially among the vulnerable populations. Methods: We conducted a scan of CHW research studies, projects and programs that demonstrate effectiveness and return on investment. We also review CHW efforts in Georgia, timeline, and stakeholders to formally recognize, advance professionalism, and fully integrate CHWs as essential and sustainable members of the healthcare team. Results: There is significant evidence for the effectiveness of CHWs and the cost-benefit of CHW programs. Georgia has ongoing formal efforts to establish a sustainable and well-trained CHW workforce Conclusions: A well-trained CHW workforce can be an important response to the transformation of Georgia’s community health practice and status, decreasing excess morbidity and mortality, and advancing health equity. Georgia should build on its own considerable experience with CHWs and the evidence of effectiveness to fully integrate CHWs into the healthcare system

Total Sitting Time and Sitting Pattern in Postmenopausal Women Differ by Hispanic Ethnicity and are Associated With Cardiometabolic Risk Biomarkers.

Background Sedentary behavior is pervasive, especially in older adults, and is associated with cardiometabolic disease and mortality. Relationships between cardiometabolic biomarkers and sitting time are unexplored in older women, as are possible ethnic differences. Methods and Results Ethnic differences in sitting behavior and associations with cardiometabolic risk were explored in overweight/obese postmenopausal women (n=518; mean±SD age 63±6 years; mean body mass index 31.4±4.8 kg/m2). Accelerometer data were processed using validated machine-learned algorithms to measure total daily sitting time and mean sitting bout duration (an indicator of sitting behavior pattern). Multivariable linear regression was used to compare sitting among Hispanic women (n=102) and non-Hispanic women (n=416) and tested associations with cardiometabolic risk biomarkers. Hispanic women sat, on average, 50.3 minutes less/day than non-Hispanic women (P<0.001) and had shorter (3.6 minutes less, P=0.02) mean sitting bout duration. Among all women, longer total sitting time was deleteriously associated with fasting insulin and triglyceride concentrations, insulin resistance, body mass index and waist circumference; longer mean sitting bout duration was deleteriously associated with fasting glucose and insulin concentrations, insulin resistance, body mass index and waist circumference. Exploratory interaction analysis showed that the association between mean sitting bout duration and fasting glucose concentration was significantly stronger among Hispanic women than non-Hispanic women (P-interaction=0.03). Conclusions Ethnic differences in 2 objectively measured parameters of sitting behavior, as well as detrimental associations between parameters and cardiometabolic biomarkers were observed in overweight/obese older women. The detrimental association between mean sitting bout duration and fasting glucose may be greater in Hispanic women than in non-Hispanic women. Corroboration in larger studies is warranted
