The Argentine ant (Linepithema humile) and the little fire ant (Wasmannia auropunctata) are among the top 100 invasive alien species globally, causing significant ecological and economic harm. Therefore, it is crucial to study their potential geographic distribution worldwide. This study aimed to predict their global distribution under current and future climate conditions. We used distribution data from various sources, including CABI, GBIF, and PIAKey, and key climate variables selected from 19 environmental factors to model their potential geographic distribution using MaxEnt. The AUC values were 0.925 and 0.937 for L. humile and W. auropunctata, respectively, indicating good predictive performance. Suitable areas for L. humile were mainly in southern North America, northern South America, Europe, central Asia, southern Oceania, and parts of Africa, while W. auropunctata suitable areas were mostly in southern North America, most of South America, a small part of Europe, southern Asia, central Africa, and some parts of Oceania. Under climate change scenario, suitable areas for L. humile increased, while highly suitable areas for W. auropunctata decreased. The top four countries with the largest areas of overlapping suitable habitat under current climate were Brazil, China, Australia, and Argentina, while under future SSP585 climate scenario, the top four countries were Brazil, China, Indonesia, and Argentina. Some countries, such as Estonia and Finland, will see an overlapping adaptation area under climate change. In conclusion, this study provides insight into controlling the spread and harm of L. humile and W. auropunctata.

There are many health and nutrition implications of suffering from multimorbidity, which is a huge challenge facing health and social services. This review focuses on malnutrition, one of the nutritional consequences of multimorbidity. Malnutrition can result from the impact of chronic conditions and their management (polypharmacy) on appetite and nutritional intake, leading to an inability to meet nutritional requirements from food. Malnutrition (undernutrition) is prevalent in primary care and costly, the main cause being disease, accentuated by multiple morbidities. Most of the costs arise from the deleterious effects of malnutrition on individual’s function, clinical outcome and recovery leading to a substantially greater burden on treatment and health care resources, costing at least £19·6 billion in England. Routine identification of malnutrition with screening should be part of the management of multimorbidity together with practical, effective ways of treating malnutrition that overcome anorexia where relevant. Nutritional interventions that improve nutritional intake have been shown to significantly reduce mortality in individuals with multimorbidities. In addition to food-based interventions, a more ‘medicalised’ dietary approach using liquid oral nutritional supplements (ONS) can be effective. ONS typically have little impact on appetite, effectively improve energy, protein and micronutrient intakes and may significantly improve functional measures. Reduced treatment burden can result from effective nutritional intervention with improved clinical outcomes (fewer infections, wounds), reducing health care use and costs. With the right investment in nutrition and dietetic resources, appropriate nutritional management plans can be put in place to optimally support the multimorbid patient benefitting the individual and the wider society.

This essay brings to light a rare feature of the Stewart legal system. Grand jury charges remain understudied, partly for want of primary source materials. The brief historical and biographical sketches of the essay are appended by a unique and relevant artifact of the time: a preamble or exhortation to a grand jury charge, ostensibly delivered by a Justice of the King's Bench, John Dodderidge.

In the context of China's “Constructing ecological civilization” initiative, Tibetan environmentalists are proactively incorporating ecological science into their wildlife conservation efforts. This ethnographic study explores the logics, rationales and motivations behind this approach among Tibetans in Qinghai province. The article contends that Tibetan environmentalists adopt ecological science to gain legibility in the eyes of both the state and the wider environmental conservation community, thereby enhancing their political legitimacy and social recognition. On one hand, this practice counters the stigmatizing narratives that depict Tibetan pastoralists as backward. By embracing scientific discourses and practices, they challenge such derogatory views and position themselves as forward-thinking conservationists. On the other hand, this strategy indirectly preserves the traditional knowledge of pastoralists. Through their involvement with ecological science, they merge traditional insights with scientific methodologies, ensuring the protection of their cultural heritage while adapting to the sociopolitical landscape of contemporary conservation dynamics in China.

Antipsychotics are commonly prescribed to manage the behavioural and psychological symptoms of dementia (BPSD) despite their modest efficacy and significant adverse effects. Psychosocial interventions are recommended as the first-line approach in treating BPSD before considering pharmacological options. A Cochrane Review by Lühnen et al (2023) evaluated the effects of psychosocial interventions on reducing antipsychotic prescription in care homes, and found that no generalisable recommendations can be made based on the currently available evidence. This commentary attempts to critically appraise and add context to the review.

The numerical range in the quaternionic setting is, in general, a non-convex subset of the quaternions. The essential numerical range is a refinement of the numerical range that only keeps the elements that have, in a certain sense, infinite multiplicity. We prove that the essential numerical range of a bounded linear operator on a quaternionic Hilbert space is convex. A quaternionic analogue of Lancaster theorem, relating the closure of the numerical range and its essential numerical range, is also provided.

I aim in this article to contribute two points to the ongoing discussion regarding strong DDS and modal collapse. First, I will examine a recent version of the modal collapse objection formulated by R. T. Mullins, demonstrating that one can modify the argument to survive its most forceful rejoinder. Having established the cogency of Mullins's modal collapse argument, I next aim to heighten the severity of the conclusion. In particular, I demonstrate that the success of the modal collapse argument entails a moral collapse wherein well-established principles of ethical reasoning fail. Finally, I examine a recent attempt by Katherine Rogers to undercut some of the unwelcomed results of a modal collapse via an appeal to the theistic multiverse. I conclude that this manoeuvre proves ineffective against the moral collapse objection.

The theory of utility is a well-known method of constructing insurance premiums (see e.g., Newton et al. (1986) Actuarial Mathematics. Itasca, Illinois: The Society of Actuaries.). Furman and Zitikis ((2008) Insurance: Mathematics and Economics, 42, 459–465.) proposed an alternative method using the mean value of a weighted random variable. According to this approach, for various choices of weighting, popular premiums such as net premium, modified variance premium, Esscher premium, and Kamps premium are obtained. On the other hand, some premiums cannot be obtained with this method, such as the premium of the exponential principle. In this paper, we provide a complementary theory by introducing a family of unimodal weighted distributions for which the mode is a premium principle.

Political scientists have long viewed values as a source of constraint in political belief systems. More recently, scholars have argued that values—particularly moral values—contribute to polarization. Yet, there is little direct and systematic research on which values are perceived as moral values. We examine 21 values, including Schwartz’s values, political values, and moral foundations. Drawing on a broad literature on cooperation, we first develop theoretical expectations for the extent of value moralization both between and within value systems. We next argue that this moralization matters because it intensifies the effects of value disagreement on social polarization. Using a probability-based survey of the US and an embedded conjoint experiment, we find substantial variation in moralization across values, and that highly moralized values are more polarizing. Our research brings together competing literatures on values and shows how moral values differentially shape polarization.
