The academic training of professionals influences the evolution and future direction of scientific disciplines. However, the training background and demographic composition of weed science faculty have not been systematically characterized. To address this, we conducted an Internet-based survey of weed science faculty at universities in the United States of America that included the academic fields of the degrees these faculty had received, the institutions that granted these degrees, which U.S. states or countries (if outside the United States) the degrees came from, the current academic rank of each faculty member, whether the faculty held leadership positions at their universities, and the gender of each faculty member. We identified 223 faculty at 50 universities. They received their degrees from institutions in 24 countries and 39 U.S. states. Most of their BS degrees were in agronomy and crop science or plant science, physiology, and genetics, with a few weed science and ecology degrees. Weed science and ecology representation increased at the MS level and became the most common doctoral training area. A plurality of the faculty were professors (48.9%), followed by assistant professors (28.7%), associate professors (19.7%), lecturers (0.9%) and unidentified rank (1.8%). Men made up 82.5% of the faculty with women at 17.5%. Men also held more of the leadership positions (84.4%) than women (15.6%). These findings provide the first comprehensive overview of the weed science academic workforce of the United States and establish a baseline for evaluating future trends in training pathways, disciplinary identity, workforce diversity, and potential continental or international comparisons.

Concordia Station is a long-term lidar observatory in Antarctica. Its main purpose is to detect and classify polar stratospheric clouds (PSCs). In September 2023, water ice PSCs were observed for a period of 6 days. This has never occurred during the month of September in the 10 years of observations of PSCs at Concordia Station. In addition, the space-borne CALIOP (Cloud Aerosol Lidar with Orthogonal Polarization) lidar observed a rare occurrence of ice PSCs over Concordia Station during the first half of June. It is well known that the January 2022 eruption of the Hunga submarine volcano (20°32’S, 175°23’W) injected vast amounts of water vapour into the stratosphere. The Hunga hydration flooded southern high latitudes at the end of the 2022 austral winter, and the moist air was then entrained into the developing vortex in the austral autumn (April–May) of 2023. The increased water vapour from Hunga was reported to promote PSC formation by cooling the stratosphere and raising PSC formation temperatures. Here, we explore the impact of the Hunga eruption on the PSCs observed at Concordia Station.

We study large deviations for Cox–Ingersoll–Ross processes with small noise and state-dependent fast switching via associated Hamilton–Jacobi–Bellman equations. As time scales separate, when the noise goes to 0 and the rate of switching goes to $\infty$, we get a limit equation characterized by the averaging principle. Moreover, we prove the large deviation principle with an action-integral form rate function to describe the asymptotic behavior of such systems. The new ingredient is establishing the comparison principle in the singular context. The proof is carried out using the nonlinear semigroup method from Feng and Kurtz’s book [14].

This review examines the role glycerophospholipids (PL) in dairy cow health, with specific focus on phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI) and phosphatidylserine (PS). Increasing parity of cows is associated with lower concentrations of plasma PL that contain very long-chain omega-3 fatty acids, including docosahexaenoic acid and eicosapentaenoic acid, which are precursors for prostaglandin synthesis, and have anti-inflammatory roles. Low concentrations of these PL could plausibly contribute to the increased risk of disease, reproductive failure and mortality in older cows. The bioavailability and metabolism of fatty acids may differ among supplements that are predominately neutral lipids, such as triacylglycerol-rich oils, and those bound to PL including pasture, whole or ground oilseeds and fish meal. Hepatic lipidosis can occur during the transition period if there is insufficient very-low density lipoproteins (VLDL) production in the liver to transport lipids into blood circulation. The PC are the primary PL of VLDL and are produced by two main pathways in the liver, the cytidine diphosphate-choline pathway that uses choline as a substrate, and the PE N-methyltransferase pathway that uses PE and methyl-donors as substrates. Co-supplementation strategies that target both pathways may increase PC production over a one-pathway supplementation strategy. The PIs are phosphoinositides precursors, which have broad physiological roles including regulating inflammatory processes and may offer targets for novel treatment and management of disease. Both the PI and PE are precursors to endocannabinoids, important regulators of energy metabolism, immune function and reproduction in mammals. Early findings on the endocannabinoid system in transition dairy cows yielded results that diverge from non-ruminant models. The PS expression on cytoplasmic membranes signals apoptosis, coagulation and contributes to sperm–oocyte recognition. As lipidomic diagnostics become increasingly available, understanding the metabolism of PL will continue to develop and promises to offer novel strategies for optimising cattle health and longevity.

The UK National Institute for Health and Care Excellence (NICE) recommends CBT for people with psychosis, yet many do not access therapies promptly, and duration of untreated psychosis predicts poorer outcomes. In addition to systemic service issues, it is likely that insecure attachment, common in people with psychosis, constitutes a key barrier to therapy. If we can articulate attachment patterns in terms of interpersonal beliefs and behaviours, we will be better placed to engage people in CBT. We used a cross-sectional design to examine theoretically predicted relationships between attachment style and (1) beliefs about self and others, (2) underlying assumptions, and (3) help-seeking intentions, across the psychosis continuum – in analogue and clinical samples. We recruited a general population analogue sample with elevated levels of non-clinical paranoia (n=172) and a clinical sample with self-reported psychosis (n=130). All completed standardised measures of attachment, beliefs about self and others, underlying assumptions and help-seeking. Regression analyses showed that insecure attachment predicted higher levels of negative self- and other-beliefs, and problematic underlying assumptions, and reduced help-seeking intentions, with some differences in patterns across analogue and clinical samples. Attachment is associated with CBT treatment targets and can inform psychological formulation and treatment. Our measure of assumptions may have been inappropriate for the clinical group. We conclude with public health, service level, and clinical implications to improve engagement and outcomes in CBT for psychosis.

Key learning aims

1. (1) Everyone with psychosis should have access to recommended treatments including CBT, but many do not.

2. (2) Insecure attachment is common in people with established psychosis or elevated levels of non-clinical paranoia, and may be a key barrier to accessing therapy.

3. (3) We show that insecure attachment is associated with (1) beliefs about self and others, (2) underlying assumptions, and (3) help-seeking intentions.

4. (4) Attachment style can inform CBT formulation and intervention, and wider service level and public health campaigns designed to improve engagement and outcomes for people with or vulnerable to psychosis.

Laser weed control is an emerging non-chemical technology made feasible by recent advances in artificial intelligence and automation. This research evaluated the response of four turf and weed species to varying levels and patterns of laser intensity to determine practical applications of laser weeding in turfgrass systems. Field experiments were conducted from July 2024 to March 2025 on research fairways in Blacksburg, VA, using a 10 W diode laser in spiral patterns with varying pattern-averaged energy densities (PAED). Two studies were implemented: one evaluated increasing energy intensity, and the other assessed combinations of line spacing, PAED, and number of passes in a factorial design. Line spacing significantly influenced weed control efficacy, with 4-mm spacing improving green cover reduction by up to 10% over denser patterns at the same PAED. Bermudagrass [Cynodon dactylon (L.) Pers.] recovered fully within 24 days post-treatment, while creeping bentgrass (Agrostis stolonifera L.) showed prolonged injury at higher intensities and wider spacings. These results demonstrate that laser weeding is feasible in turfgrass systems, especially with optimized energy and pattern configurations, and highlight the need for pattern customization to balance weed control with turfgrass safety.

Vegans face a problem, at least if they base their arguments upon principles against causing harm. As Donald Bruckner (2020) has pointed out, these same principles risk ruling out a great many other practices – even eating dessert. Eating dessert risks being impermissible because of the crop deaths associated with agricultural practices, especially the use of insecticides and rodenticides. I suggest that the extent to which this problem emerges depends on the exact principle vegans appeal to. Under some principles against causing harm, the problem indeed stands. I suggest that the vegan has a couple of options for escaping this problem. She might appeal to a principle that doesn’t have such implications. Alternatively, she might simply bite the bullet and accept that morality really is much more demanding here than we might have thought. I’ll give some reasons why biting this bullet isn’t as bad an option as one might suppose.

Tech innovations have the potential to disrupt traditional banking by unbundling banking, money, and payments; however, their impact on the cross-border payments system (CBPS) – which still relies on correspondent banking (CoBanking) networks – remains uncertain. This uncertainty is compounded by the literature’s tendency to distinguish between cash clearing and credit and to focus on the latter. Challenging this distinction, the article offers a historical perspective on the role of credit in CoBanking and international payments. It reveals the deep-rooted importance of credit in the CBPS and highlights correspondent banks’ role in providing it. But deep-rooted does not mean static. Indeed, changes in bank-intermediated trade finance practices during and after WWI reshaped the London-based CoBanking network. Furthermore, cash clearing and credit operations remained remarkably congruent until at least the 1980s, as reflected in banks’ internal organisation, reporting, and contemporaries’ descriptions of the payment system. The article argues that adopting a definition of payment systems that integrates both cash clearing and credit is essential to understanding the history of CoBanking and how it supports the CBPS. It suggests that relying on tech firms to provide the elastic payments infrastructure the economy requires could equate to jumping out of the frying pan and into the fire.

Many mergers and acquisitions (M&As) fail, and an emerging body of literature highlights the role of prejudice in derailing the M&A process. While prejudice is frequently observed in M&As, strategies to mitigate these biases remain underexplored. Adopting a qualitative case study approach, this study focuses on Chinese acquisitions in the UK and examines how managers from both the acquired and acquiring organizations navigate prejudice through emotional sensemaking. The findings demonstrate that emotional sensemaking plays a critical role in shaping the post-acquisition integration (PAI) process and its outcomes. Specifically, sensemaking supported by emotional intelligence facilitates the accommodation or reduction of prejudice, while emotionally unintelligent sensemaking tends to reinforce it. By focusing on the dynamic, interactive emotional exchanges between managers at the micro level, this study offers a fresh lens on the integration process beyond traditional strategic or structural explanations. The study contributes to the literature by advancing the understanding of micro-level emotional sensemaking in the PAI, emphasizing the dynamic, interactive nature of emotional sensemaking between acquirer and acquiree managers, and its impact on the integration process and outcomes.
