The southern United States produces 90% of the nation’s cotton, and the Texas High Plains is the largest contiguous cotton producing region. Since 2011, glyphosate-resistant Palmer amaranth has complicated cotton production, and alternatives to glyphosate are needed. Integrating soil residual herbicides into a weed management program is a crucial step to control glyphosate resistant weeds before emergence. The recent development of p-hydroxyphenylpyruvate dioxygenase (HPPD)-resistant cotton by BASF Corporation may allow growers to use isoxaflutole in future weed management programs. In 2019 and 2020, field experiments were conducted in New Deal, Lubbock, and Halfway, Texas, to evaluate HPPD-resistant cotton response to isoxaflutole applied preemergence (PRE) or early postemergence (EPOST) and to determine the efficacy of isoxaflutole when used as part of a season-long weed management program. At the New Deal location, cotton response was observed following the EPOST application, but it never exceeded 10%. Cotton response was greatest following the PRE application in Lubbock in 2019 but did not exceed 14%. In 2020 in Lubbock, cotton was replanted due to severe weather. There was <1% cotton response following the PRE application, and maximum cotton response observed was 9% following EPOST and mid-postemergence (MPOST) applications. Cotton lint yields were not different from those of the nontreated, weed-free control at either location. In non-crop weed control studies in Halfway, all treatments controlled Palmer amaranth ≥94% 21 d after the EPOST application. Twenty-one days after the MPOST treatment, systems with isoxaflutole applied EPOST controlled Palmer amaranth by 88% to 93%, while systems with isoxaflutole PRE controlled Palmer amaranth by 94% to 98%. End-of-season Palmer amaranth control was lowest in the system without isoxaflutole (88%) and when isoxaflutole was used EPOST (88% to 91%). These studies suggest that the use of isoxaflutole in cotton weed management systems may improve season-long control of several troublesome weeds with no adverse effects on cotton yield and quality.

Over the past 20 years, collaboration has become an essential aspect of archaeological practice in North America. In paying increased attention to the voices of descendant and local communities, archaeologists have become aware of the persistent injustices these often marginalized groups face. Building on growing calls for a responsive and engaged cultural heritage praxis, this forum article brings together a group of Native and non-Native scholars working at the nexus of history, ethnography, archaeology, and law in order to grapple with the role of archaeology in advancing social justice. Contributors to this article touch on a diverse range of critical issues facing Indigenous communities in the United States, including heritage law, decolonization, foodways, community-based participatory research, and pedagogy. Uniting these commentaries is a shared emphasis on research practices that promote Indigenous sovereignty and self-determination. In drawing these case studies together, we articulate a sovereignty-based model of social justice that facilitates Indigenous control over cultural heritage in ways that address their contemporary needs and goals.

The current catastrophic decline in African vultures is caused mainly by poisoning, and killing for consumption and belief-based use (traditional medicine). To find out more about the key threats to vultures in West Africa, we assessed the main anthropogenic causes of vulture mortality in Burkina Faso. We analysed incidents of mass vulture mortality, based on interviews conducted in 2016 with local butchers, veterinarians, foresters, and abattoir watchmen at 44 sites across the country. A total of 730 interviews revealed that poisoning was the main cause of mortality of vultures in Burkina Faso (20 of the 23 mass mortality incidents described by respondents were caused by poisoning). Poisoning was also the most lethal threat to vultures (779 out of 879 known vulture deaths were due to poisoning). According to the survey, intentional poisoning of vultures with poisoned baits (which comprised 15 out of 23 mass mortality incidents) produced the highest number of victims (577 out of 879 dead vultures). The number of vultures killed by poisoned baits was higher closer to the borders than elsewhere in Burkina Faso and we believe these recent intentional vulture poisoning events in Burkina Faso were intended to meet the growing demand for vulture body parts in West Africa. The survey showed that unintentional poisoning was the second main cause of vulture mass mortality (5 out of 23 mass mortality incidents comprising 202 of 879 dead vultures). Other important anthropogenic causes of vulture mortality included electrocution at electricity poles and motor vehicle collisions. Our results highlight the need for awareness campaigns, improved policy and legislation, and stronger commitment from governments in West Africa, to halt the trade in vultures and prevent their extirpation.

Adults who had non-edematous severe acute malnutrition (SAM) during infancy (i.e., marasmus) have worse glucose tolerance and beta-cell function than survivors of edematous SAM (i.e., kwashiorkor). We hypothesized that wasting and/or stunting in SAM is associated with lower glucose disposal rate (M) and insulin clearance (MCR) in adulthood.

We recruited 40 nondiabetic adult SAM survivors (20 marasmus survivors (MS) and 20 kwashiorkor survivors (KS)) and 13 matched community controls. We performed 150-minute hyperinsulinaemic, euglycaemic clamps to estimate M and MCR. We also measured serum adiponectin, anthropometry, and body composition. Data on wasting (weight-for-height) and stunting (height-for-age) were abstracted from the hospital records.

Children with marasmus had lower weight-for-height z-scores (WHZ) (−3.8 ± 0.9 vs. −2.2 ± 1.4; P < 0.001) and lower height-for-age z-scores (HAZ) (−4.6 ± 1.1 vs. −3.4 ± 1.5; P = 0.0092) than those with kwashiorkor. As adults, mean age (SD) of participants was 27.2 (8.1) years; BMI was 23.6 (5.0) kg/m2. SAM survivors and controls had similar body composition. MS and KS and controls had similar M (9.1 ± 3.2; 8.7 ± 4.6; 6.9 ± 2.5 mg.kg−1.min−1 respectively; P = 0.3) and MCR. WHZ and HAZ were not associated with M, MCR or adiponectin even after adjusting for body composition.

Wasting and stunting during infancy are not associated with insulin sensitivity and insulin clearance in lean, young, adult survivors of SAM. These data are consistent with the finding that glucose intolerance in malnutrition survivors is mostly due to beta-cell dysfunction.

BASF Corp. has developed p-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor–resistant cotton and soybean that will allow growers to use isoxaflutole in future weed management programs. In 2019 and 2020, a multi-state non-crop research project was conducted to examine weed control following isoxaflutole applied preemergence alone and with several tank-mix partners at high and low labeled rates. At 28 d after treatment (DAT), Palmer amaranth was controlled ≥95% at six of seven locations with isoxaflutole plus the high rate of diuron or fluridone. These same combinations provided the greatest control 42 DAT at four of seven locations. Where large crabgrass was present, isoxaflutole plus the high rate of diuron, fluridone, pendimethalin, or S-metolachlor or isoxaflutole plus the low rate of fluometuron controlled large crabgrass ≥95% in two of three locations 28 DAT. In two of three locations, isoxaflutole plus the high rate of pendimethalin or S-metolachlor improved large crabgrass control 42 DAT when compared to isoxaflutole alone. At 21 DAT, morningglory was controlled ≥95% at all locations with isoxaflutole plus the high rate of diuron and at three of four locations with isoxaflutole plus the high rate of fluometuron. At 42 DAT at all locations, isoxaflutole plus diuron or fluridone and isoxaflutole plus the high rate of fluometuron improved morningglory control compared to isoxaflutole alone. These results suggest that isoxaflutole applied preemergence alone or in tank mixture is efficacious on a number of cross-spectrum annual weeds in cotton, and extended weed control may be achieved when isoxaflutole is tank-mixed with several soil-residual herbicides.

The workhouse remains a totemic institution for social historians, yet we still know very little about the day-to-day experiences of the indoor poor. Nowhere is this clearer than in discussions about workhouse clothing, which remain overwhelmingly negative in the literature and consistent with the predominant view of the workhouse as a place of suffering and humiliation. Yet more often than not, this view is based on relatively shallow empirical foundations and tends to rely on anecdotal evidence or on the uncritical use of subjective sources such as photographs, newspaper editorials and other cultural products. This article takes a different approach by looking again at the whole range of meanings that workhouse clothing held for paupers and those who oversaw its allocation, and at the practical and symbolic usages to which it was put by them. On the basis of this evidence the authors argue that, contrary to the orthodox view, workhouse clothing was rarely intended to be degrading or stigmatising; that it would have held very different meanings for different classes of paupers; and that, far from being a source of unbridled misery, paupers often found it to be a source of great strategic and practical value.

In April of 1915, the German-Jewish chemist Fritz Haber supervised the first deployment of industrialized chemical weapons against French colonial troops. The uncertain nature of the attack, both in its execution and outcome, led many German military men to question the controllability of poison gas. Over the next three decades, Germans would continue this line of inquiry, as aero-chemical attacks appeared increasingly imminent. This article narrates the German search for control over chemical weapons between the world wars, revealing the ways in which interwar techno-nationalists tied the mastery of poison gas to ethno-racial definitions of Germanness. Under the Nazis, leaders in civilian aero-chemical defense picked up this interwar thread and promoted a dangerous embrace of gas that would supposedly cull the technically superior Germans from other lesser races. Although this vision of a chemically saturated world did not suffuse German society, such logic did play out in the gas chambers of the Holocaust.

Women with underlying cardiac conditions have an increased risk of adverse pregnancy outcomes. Counselling reproductive age women with heart disease is important to assist them in deciding whether to pursue pregnancy, to ensure their best cardiovascular status prior to pregnancy, and that they understand the risks of pregnancy for them and baby. This also provides an opportunity to explore management strategies to reduce risks. For this growing cohort of women, there is a great need for pre-conceptual counselling.

This retrospective comparative audit assessed new referrals and pre-conceptual counselling of women attending a joint obstetric–cardiology clinic at a tertiary maternity centre in a 12-month period of 2015–2016 compared with 2018–2019. This reflected the timing of the introduction of a multidisciplinary meeting prior to clinics and assessed the impact on referrals with the introduction of the European Society of Cardiology guidelines.

Data were reviewed from 56 and 67 patients in respective audit periods. Patient’s risk was stratified using modified World Health Organization classification.

Less than 50% of women with pre-existing cardiac conditions had received pre-conceptual counselling, although half of them had risks clearly documented. The majority of patients had a recent electrocardiograph and echocardiogram performed prior to counselling, and there was a modest improvement in the number of appropriate functional tests performed between time points. One-third of patients in both cohorts were taking cardiac medications during pregnancy.

There was a significant increase in the number of pregnant women with cardiac disease and in complexity according to modified World Health Organization risk classification. While there have been improvements, it is clear that further work to improve availability and documentation of pre-pregnancy counselling is needed.

Potential yield losses in grain sorghum due to weed interference based on quantitative data from the major grain sorghum-growing areas of the United States are reported by the WSSA Weed Loss Committee. Weed scientists and extension specialists who researched weed control in grain sorghum provided data on grain sorghum yield loss due to weed interference in their region. Data were requested from up to 10 individual experiments per calendar year over 10 yr between 2007 and 2016. Based on the summarized information, farmers in Arkansas, Kansas, Missouri, Nebraska, South Dakota, and Texas would potentially lose an average of 37%, 38%, 30%, 56%, 61%, and 60% of their grain sorghum yield with no weed control, and have a corresponding annual monetary loss of US $19 million, 302 million, 7 million, 32 million, 25 million, and 314 million, respectively. The overall average yield loss due to weed interference was estimated to be 47% for this grain sorghum-growing region. Thus, US farmers would lose approximately 5,700 million kg of grain sorghum valued at approximately US $953 million annually if weeds are not controlled. With each dollar invested in weed management (based on estimated weed control cost of US $100 ha−1), there would be a return of US $3.80, highlighting the return on investment in weed management and the importance of continued weed science research for sustaining high grain sorghum yield and profitability in the United States.

Cybermentoring refers to virtual peer support in which young people themselves are trained as cybermentors and interact with those needing help and advice (cybermentees) online. This article describes the training in, and implementation of, a cross-national cybermentoring scheme, Beatbullying Europe, developed in the United Kingdom. It involved train-the-trainer workshops for partners and life mentors in six European countries (Italy, Spain, Portugal, Romania, Poland and the Czech Republic) in 2013–2014, followed by training sessions for pupil cybermentors aged 11–16 years. Although BeatBullying went into liquidation in November 2014, the project was largely completed. We (1) report an evaluation of the training of the life mentors and mentors, via questionnaire survey; and (2) discuss findings about the implementation of the scheme and its potential at a cross-national level, via partner interviews during and at the end of the project. The training was found to be highly rated in all respects, and in all six countries involved. The overall consensus from the data available is that there was a positive impact for the schools and professionals involved; some challenges encountered are discussed. The BeatBullying Europe project, despite being unfinished, was promising, and a similar approach deserves further support and evaluation in the future.
