A Rank Forum was convened to discuss the evidence around food insecurity (FIS), its impact on health, and interventions which could make a difference both at individual and societal level, with a focus on the UK. This paper summarises the proceedings and recommendations. Speakers highlighted the growing issue of FIS due to current economic and social pressures. It was clear that the health implications of FIS varied geographically since food insecure women in higher income regions tend to be living with overweight or obesity, in contrast to those living in low-to-middle income countries. This paradox could be due to stress and/or metabolic or behavioural responses to an unpredictable food supply. The gut microbiota may play a role given the negative effects of low fibre diets on bacterial diversity, species balance and chronic disease risk. Solutions to FIS involve individual behavioural change, targeted services and societal/policy change. Obesity-related services are currently difficult to access. Whilst poverty is the root cause of FIS, it cannot be solved simply by making healthy food cheaper due to various ingrained beliefs, attitudes and behaviours in target groups. Person-centred models, such as Capability-Opportunity-Motivation Behavioural Change Techniques and Elicit-Provide-Elicit communication techniques are recommended. Societal change or improved resilience through psychological support may be more equitable ways to address FIS and can combine fiscal or food environment policies to shift purchasing towards healthier foods. However, policy implementation can be slow to enact due to the need for strong evidence, consultation and political will. Eradicating FIS must involve co-creation of interventions and policies to ensure that all stakeholders reach a consensus on solutions.

A Bayesian procedure is given for estimation in unrestricted common factor analysis. A choice of the form of the prior distribution is justified. It is shown empirically that the procedure achieves its objective of avoiding inadmissible estimates of unique variances, and is reasonably insensitive to certain variations in the shape of the prior distribution.

The global population and status of Snowy Owls Bubo scandiacus are particularly challenging to assess because individuals are irruptive and nomadic, and the breeding range is restricted to the remote circumpolar Arctic tundra. The International Union for Conservation of Nature (IUCN) uplisted the Snowy Owl to “Vulnerable” in 2017 because the suggested population estimates appeared considerably lower than historical estimates, and it recommended actions to clarify the population size, structure, and trends. Here we present a broad review and status assessment, an effort led by the International Snowy Owl Working Group (ISOWG) and researchers from around the world, to estimate population trends and the current global status of the Snowy Owl. We use long-term breeding data, genetic studies, satellite-GPS tracking, and survival estimates to assess current population trends at several monitoring sites in the Arctic and we review the ecology and threats throughout the Snowy Owl range. An assessment of the available data suggests that current estimates of a worldwide population of 14,000–28,000 breeding adults are plausible. Our assessment of population trends at five long-term monitoring sites suggests that breeding populations of Snowy Owls in the Arctic have decreased by more than 30% over the past three generations and the species should continue to be categorised as Vulnerable under the IUCN Red List Criterion A2. We offer research recommendations to improve our understanding of Snowy Owl biology and future population assessments in a changing world.

Prosody includes the pitch, timing and loudness in speech, which can convey meaning and emotion. This study examines whether prosodic categories affect novel noun learning and whether the referent characteristic influence learning. Previous research showed that emotional prosody interfered with adults’ noun learning (West et al., 2017), but it had no effect on children (West et al., 2022). However, these researchers varied their method across ages, including animacy and complexity of the referent, and it is unclear if the results extend beyond the three emotional prosodies tested. Participants in the current set of studies heard novel words presented in five prosodic categories (within-subject) in order to learn the label for either animate or inanimate objects (between-subject). Study 1 compared inanimate objects and aliens, with better noun learning performance for inanimate objects. Study 2 compared inanimate objects with the same objects with faces added, but there was no difference in noun learning by object type. Both studies showed differences in noun learning by the prosodic category, with warning less accurate than naming. These results demonstrate how extralinguistic factors like prosody, attention and referent complexity influence noun learning.

Calcium-sodium exchange on Wyoming bentonite in methanol, ethanol and acetone-water systems were investigated at 0.03 N Cl and at room temperature. Calcium-sodium exchange isotherms were plotted at cosolvent concentrations ranging from 0 to 70% wt./wt. using Ca and Na ionic activities before and after correction for CaCl+ formation. In both cases and in all treatments, a greater selectivity of bentonite surfaces for Ca ions was observed. When compared to water, different trends were observed among and within cosolvents. These trends varied depending on whether or not CaCl+ formation was accounted for. Ignoring the formation of CaCl+, the preference of bentonite for Ca increased in methanolwater systems with increased percent methanol at low equivalent Ca fraction (<0.2). At higher Ca fractions, this preference matched that of water. In ethanol-water, no increased preference of the surface for Ca was observed. In acetone-water, increasing cosolvent concentration decreased the preference of the surface for Ca. The magnitude of this decrease was larger at low equivalent Ca fraction (<0.2). After correction for CaCl+, both in solution and on the surface, the preference of bentonite for Ca2+ was larger in methanol- and ethanol-water systems. In acetone-water, increased surface preference for Ca was only apparent at low acetone fractions (<50%). At higher acetone fractions, there was evidence of increased Na loading but no increase in Ca2+ selectivity. Clearly, ion-pair formation and its effects on Ca-Na exchange reactions cannot be ignored in mixtures of aqueous-organic solvents. After accounting for this effect, Ca-Na exchange in the studied solvents appears to be more of a surface- than a solution-controlled phenomenon that involves both electrostatic and specific solvent-surface types of interactions that have not been elucidated.

Zooanthropy (delusional beliefs of turning into an animal) is a rare but well recognised psychiatric phenomenon. This case describes the presence of kynanthropic delusions (delusional beliefs of turning into a dog). Multiple other psychotic symptoms were also evident including unusually the additional presence of delusions of vampirism. Delusional beliefs in this case were associated with behavioural changes including growling and barking, and less commonly an expressed craving for biting people’s necks to suck human blood. Symptom intensity was associated with increased psychosocial stressors for this patient, with some benefit noted from very high doses of anti-psychotic medications. Brief admissions to the acute psychiatric inpatient unit and thus removal from environmental stressors has been associated with an amelioration in symptomatology.

Cybervetting is the widespread practice of employers culling information from social media and/or other internet sources to screen and select job candidates. Research evaluating online screening is still in its infancy; that which exists often assumes that it offers value and utility to employers as long as they can avoid discrimination claims. Given the increasing prevalence of cybervetting, it is extremely important to probe its challenges and limitations. We seek to initiate a discussion about the negative consequences of online screening and how they can be overcome. We draw on previous literature and our own data to assess the implications of cybervetting for three key stakeholders: job candidates, hiring agents, and organizations. We also discuss future actions these stakeholders can take to manage and ameliorate harmful outcomes of cybervetting. We argue that it is the responsibility of the organizations engaged in cybervetting to identify specific goals, develop formal policies and practices, and continuously evaluate outcomes so that negative societal consequences are minimized. Should they fail to do so, professional and industry associations as well as government can and should hold them accountable.

Maize is the primary staple crop cultivated during the monsoon season in eastern India. However, yield gaps are large because of multiple factors, including low adoption rates of good agronomic management practices. This study aimed to narrow the maize yield gap using diverse agronomic and varietal interventions through field experiments over 2 years (2013–2014) in the rainfed plateau region of Odisha. As a result, maize yield increased by 0.9, 0.74, and 0.17 Mg ha−1 under optimum plant population, fertilizer management, and herbicide-based weed management, respectively, over farmers’ current practices (Check). Moreover, when all three interventions were combined (‘best’ management practice), grain yields increased by 1.7 Mg ha−1 in conservation tillage and 2.2 Mg ha−1 in conventional tillage. We also observed that the combination of long-duration hybrids and best management practices (BMPs) increased grain yield by 4.0 Mg ha−1 and profitability by $888 ha−1 over farmers’ current practices. In addition, Nutrient Expert decision support tool-based fertilizer management along with BMPs increased grain yield by 1.7 Mg ha−1 and profitability by $314 ha−1 over farmers’ fertilizer practices (Check). These results suggest that the combination of maize hybrids and BMPs can improve the productivity and profitability of rainfed maize in the plateau region of Odisha. However, these entry points for intensification need to be placed in the context of varying investment requirements, input and output market conditions, and matched with farmer preferences and risk.

There has been an increasing interest in intergenerational activities where young people and older adults work together in the exchange of knowledge, new ideas, methodologies and ways of thinking. With the leading international climate change conference in Glasgow in Nov. 2021, this paper presents an intergenerational co-design COP26 project where co-design pairs designed and made Glasgow COP26 souvenirs, exhibited and sold them in a COP26 ‘pop-up’ shop. The project delivered important learning and teaching including project launch, studio sessions, external design reviews, and prototyping.

To overcome grass supply shortages on the main grazing block, some pasture-based dairy farmers are using zero-grazing (also known as ‘cut and carry’), whereby cows are periodically housed and fed fresh grass harvested from external land blocks. To determine the effect of zero-grazing on cow performance, two early-lactation experiments were conducted with autumn and spring-calving dairy cows. Cows were assigned to one of two treatments in a randomized complete block design. The two treatments were zero-grazing (ZG) and grazing (G). The ZG group were housed and fed zero-grazed grass, while the G group grazed outdoors at pasture. Both treatments were fed perennial ryegrass (Lolium perenne L.) from the same paddock. In experiment 1, 24 Holstein Friesian cows (n = 12) were studied over a 35-day experimental period in autumn and offered fresh grass, grass silage, ground maize and concentrates. In experiment 2, 30 Holstein Friesian cows (n = 15) were studied over a 42-day experimental period and offered fresh grass and concentrates. Average dry matter intake and milk yield was similar for ZG and G in both experiments. Likewise, ZG did not have an effect on milk composition, body condition or locomotion. Zero-grazing had no effect on total nitrogen excretion or nitrogen utilization efficiency in either experiment, or on rumen pH and ammonia concentration in experiment 1. While zero-grazing may enable farmers to supply fresh grass to early-lactation cows in spring and autumn, results from this study suggest that there are no additional benefits to cow performance in comparison to well-managed grazed grass.

Repeated antigen testing of 12 severe acute respiratory coronavirus virus 2 (SARS-CoV-2)–positive nursing home residents using Abbott BinaxNOW identified 9 of 9 (100%) culture-positive specimens up to 6 days after initial positive test. Antigen positivity lasted 2–24 days. Antigen positivity might last beyond the infectious period, but it was reliable in residents with evidence of early infection.
