Published: May 2024

AbstractNon‐radiative recombination losses limit the property of perovskite solar cells (PSCs). Here, a synergistic strategy of SnSe2QDs doping into SnO2 and chlorhexidine acetate (CA) coating on the surface of perovskite is proposed. The introduction of 2D SnSe2QDs reduces the oxygen vacancy defects and increases the carrier mobility of SnO2. The optimized SnO2 as a buried interface obviously improves the crystallization quality of perovskite. The CA containing abundant active sites of ─NH2/─NH─, ─C═N, CO, ─Cl groups passivate the defects on the surface and grain boundary of perovskite. The alkyl chain of CA also improves the hydrophobicity of perovskite. Moreover, the synergism of SnSe2QDs and CA releases the residual stress and regulates the energy level arrangement at the top and bottom interface of perovskite. Benefiting from these advantages, the bulk and interface non‐radiative recombination loss is greatly suppressed and thereby increases the carrier transport and extraction in devices. As a result, the best power conversion efficiency (PCE) of 23.41% for rigid PSCs and the best PCE of 21.84% for flexible PSCs are reached. The rigid PSC maintains 89% of initial efficiency after storing nitrogen for 3100 h. The flexible PSCs retain 87% of the initial PCE after 5000 bending cycles at a bending radius of 5 mm.
Bias in perceptual learning
Authors: Ransom Madeleine , Goldstone Robert L. 
Published: May 2024

AbstractPerceptual learning is commonly understood as conferring some benefit to the learner, such as allowing for the extraction of more information from the environment. However, perceptual learning can be biased in several different ways, some of which do not appear to provide such a benefit. Here we outline a systematic framework for thinking about bias in perceptual learning and discuss how several cases fit into this framework. We argue these biases are compatible with an understanding in which perceptual learning is beneficial, but that its benefits are tied to both a person's narrow interests and the training environment or domain, and so if there are changes to either of these, then benefits can turn into liabilities, though these are often temporary.This article is categorized under:

How students learn to lead in pre‐ and early‐career experiences
Authors: Di Pede Graziana 
Published: May 2024

AbstractThis study illuminates the leadership experiences of undergraduate business students undertaking a 1‐year work placement. Semi‐structured interviews and reflective journals were used to explore the students’ leadership experiences before and during their placement. Through reflection on these experiences, students were able to make sense of their own leadership learning as well as develop their leadership identity. A main contribution of this study has been the formulation of a theoretical model that fully acknowledges prior lived experience, and the multi‐layered and complex process of leadership identity development.
Trend to Equilibrium for Run and Tumble Equations with Non-uniform Tumbling Kernels
Authors: Evans Josephine , Yoldaş Havva 
Published: May 2024

AbstractWe study the long-time behaviour of a run and tumble model which is a kinetic-transport equation describing bacterial movement under the effect of a chemical stimulus. The experiments suggest that the non-uniform tumbling kernels are physically relevant ones as opposed to the uniform tumbling kernel which is widely considered in the literature to reduce the complexity of the mathematical analysis. We consider two cases: (i) the tumbling kernel depends on the angle between pre- and post-tumbling velocities, (ii) the velocity space is unbounded and the post-tumbling velocities follow the Maxwellian velocity distribution. We prove that the probability density distribution of bacteria converges to an equilibrium distribution with explicit (exponential for (i) and algebraic for (ii)) convergence rates, for any probability measure initial data. To the best of our knowledge, our results are the first results concerning the long-time behaviour of run and tumble equations with non-uniform tumbling kernels.

AbstractPlant invasions are a widespread and recurring phenomenon that cause significant economic and environmental damage. Invasive alien conifers are weeds that are not only costly to manage, but consistently reinvade after management efforts. Understanding how many seeds survive to germinate is a key part in understanding the weed life cycle puzzle. Here we investigated the contribution that seed predators have on reducing invasive alien conifer seed survival across both invaded and uninvaded habitats in Aotearoa New Zealand. We combined quantitative and qualitative experiments to measure seed predation across invaded and uninvaded habitats, as well as to identify which fauna are the most prolific seed predators. We utilised ex-situ empirical evidence with in-situ observations to provide realistic impacts from different seed predator species. We found that introduced mammals, particularly rodents, were the primary seed predators of invasive conifers. Seed predation pressure was highest in herbicide treated invasive alien conifer forests, indigenous beech forests, and managed pasture containing grazing livestock. Indigenous tussock areas support fewer vertebrate seed predators and as a result are particularly vulnerable to conifer invasion. The majority of seed predation occurs within the first two weeks post-dispersal. These results suggest that introduced mammal control operations, which are essential to protect endemic New Zealand species, will likely result in increasing invasive conifer populations by reducing seed predation pressure. Seed predation varies greatly between habitats, suggesting invasion and reinvasion rates are higher in ungrazed areas of lower forest density that support fewer introduced mammals.
Characterisation of the Arabidopsis thaliana telomerase TERT-TR complex

Published: May 2024

AbstractMost eukaryotic organisms employ a telomerase complex for the maintenance of chromosome ends. The core of this complex is composed of telomerase reverse transcriptase (TERT) and telomerase RNA (TR) subunits. The TERT reverse transcriptase (RT) domain synthesises telomeric DNA using the TR template sequence. The other TERT domains contribute to this process in different ways. In particular, the TERT RNA-binding domain (TRBD) interacts with specific TR motif(s). Using a yeast 3-hybrid system, we show the critical role of Arabidopsis thaliana (At) TRBD and embryophyta-conserved KRxR motif in the unstructured linker preceding the TRBD domain for binding to the recently identified AtTR subunit. We also show the essential role of the predicted P4 stem and pseudoknot AtTR structures and provide evidence for the binding of AtTRBD to pseudoknot and KRxR motif stabilising interaction with the P4 stem structure. Our results thus provide the first insight into the core part of the plant telomerase complex.
How slurs enact norms, and how to retract them
Authors: Marques Teresa 
Published: May 2024

AbstractThe present paper considers controversial utterances that were erroneously taken as derogatory. These examples are puzzling because, despite the audiences’ error, many speakers retract and even apologise for what they didn’t say and didn’t do. In recent years, intuitions about retractions have been used to test semantic theories. The cases discussed here test the predictive power of theories of derogatory language and help us to better understand what is required to retract a slur. The paper seeks to answer three questions: are the cases considered genuine retractions? If the speakers didn’t derogate by using a slur, how are the cases retractions ofderogatory acts? Do these examples support expressive accounts of slurs? I argue that the examples provide evidence for an expressivist account of slurs: a slurring utterance (defeasibly) makes a derogatory speech act where the speaker expresses a commitment to a morally questionable appraisal state, such as disgust or contempt for a target group. A retraction of a derogatory speech act requires undoing the enactment of that commitment, which can be achieved with a genuine apology. This helps explain the conduct of audiences who misunderstand what the speaker says, and the speakers’ reactions.
Enhancing the physicochemical properties of nickel cobaltite catalyst for oxygen evolution reaction in anion exchange membrane water electrolyzers
Authors: Flores Charles Lois I. , Gupta Gaurav , Mamlouk Mohamed , Balela Mary Donnabelle L. 
Published: May 2024

AbstractHierarchical hollow urchin-like nickel cobaltite (NiCo2O4) was synthesized using a two-step hydrothermal method. The effects of metal composition and surfactant addition on the morphology, structure, and electrochemical performance toward oxygen evolution reaction (OER) were investigated. The addition of cetyltrimethylammonium bromide (CTAB) reduced particle aggregation, resulting in a higher electrochemical active surface area and electrical conductivity. Lowering the Ni content from 1.0 to 0.25 did not alter the morphology and structure of the product to any extent. However, the crystallite size slightly increased. Among the spinels with different Ni and Co compositions, NiCo2O4 exhibited a superior OER electrocatalytic activity, achieving a 380 mV overpotential at 10 mA/cm2 current density. It also delivered a good performance in an anion exchange membrane water electrolyzer (AEMWE) using 1 M NaOH at 60 °C, reaching a current density of about 420 mA/cm2 at a cell voltage of 1.95 V.

Abstract
Background
Delirium is common among elderly patients in the intensive care unit (ICU) and is associated with prolonged hospitalization, increased healthcare costs, and increased risk of death. Understanding the potential risk factors and early prevention of delirium is critical to facilitate timely intervention that may reverse or mitigate the harmful consequences of delirium.

Aim
To clarify the effects of pre-admission falls on ICU outcomes, primarily delirium, and secondarily pressure injuries and urinary tract infections.

Methods
The study relied on data sourced from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Statistical tests (Wilcoxon rank-sum or chi-squared) compared cohort characteristics. Logistic regression was employed to investigate the association between a history of falls and delirium, as well as secondary outcomes, while Kaplan–Meier survival curves were used to assess short-term survival in delirium and non-delirium patients.

Results
Study encompassed 22,547 participants. Delirium incidence was 40%, significantly higher in patients with a history of falls (54.4% vs. 34.5%, p < 0.001). Logistic regression, controlling for confounders, not only confirmed that a history of falls elevates the odds of delirium (OR: 2.11; 95% CI: 1.97–2.26; p < 0.001) but also showed it increases the incidence of urinary tract infections (OR:1.50; 95% CI:1.40–1.62; p < 0.001) and pressure injuries (OR:1.36; 95% CI:1.26–1.47; p < 0.001). Elderly delirium patients exhibited lower 30-, 180-, and 360-day survival rates than non-delirium counterparts (all p < 0.001).

Conclusions
The study reveals that history of falls significantly heighten the risk of delirium and other adverse outcomes in elderly ICU patients, leading to decreased short-term survival rates. This emphasizes the critical need for early interventions and could inform future strategies to manage and prevent these conditions in ICU settings.
Assessment of the phenotypic severity of hemophilia A: using rotational thromboelastometry (ROTEM) and APTT-clot waveform analysis
Authors: Gupta Deepika , Arya Vandana , Dass Jasmita , Gupta Nitin , Kalra Manas , Sachdeva Anupam , Kotwal Jyoti 
Published: May 2024

Abstract
Background
Hemophilia A (HA) is an X-linked inherited bleeding disorder caused by reduced factor VIII (FVIII) levels. Approximately 10–15% of patients with severe HA (SHA) do not present with the anticipated bleeding pattern. Here, we assessed the phenotypic severity of hemophilia A using rotational thromboelastometry (ROTEM) and activated partial thromboplastin time-clot waveform analysis (APTT-CWA).

Methods
Patients diagnosed with hemophilia A were enrolled. Clinical phenotype assignment was performed according to the published literature, and patients were classified into four phenotypic subgroups. The whole blood sample was first run on ROTEM in INTEM mode using platelet-poor plasma, APTT was run, and the APTT-CWA graph was simultaneously recorded.

Results
A total of 66 patients were recruited for this study. Statistically significant differences were observed between the four phenotypically categorized groups using ROTEM and APTT-CWA. On comparing patients with mild/moderate-to-severe phenotypes (Group II) with SHA without inhibitors (Group IV), no significant difference was found for all parameters of ROTEM or APTT-CWA. The MCF, MA30, MAXV, and Alpha angle values using ROTEM were found to be the lowest in patients with SHA with inhibitors, which helped differentiate them from those with SHA without inhibitors. However, these two groups could not be differentiated using the APTT-CWA parameters.

Conclusion
ROTEM can be used to distinguish patients with SHA with inhibitors from those with SHA without inhibitors using a combination of parameters with high sensitivity and specificity. However, APTT-CWA cannot be used to differentiate these patient groups.
Collecting for Closure
Authors: Hick Darren Hudson 
Published: May 2024

Abstract
In this paper, I consider a peculiar feature of the aesthetics of collecting comics: collecting to complete a narrative. Unlike other forms of narrative engagement, comics are often read out of narrative sequence, and so collectors hunt for missing issues to fill in an incomplete story, leading to a “gappy” experience of the narrative. This “gappy” experience, I argue, has its own aesthetic quality and value, and I connect my analysis of the experience to both classical Kantian aesthetics and contemporary neuropsychology.
Is political anxiety different than general anxiety?
Authors: Weinschenk Aaron , Smith Kevin 
Published: May 2024

AbstractRecently, there has been growing interest in the concept of political anxiety. One important question that remains unanswered is whether political anxiety is just a symptom of general anxiety—that those reporting anxiety tied to politics are the same individuals who would already score highly on measures of general anxiety. Using survey data collected in 2023 (N = 436), we find that measures of political and generalized anxiety do not appear to be tapping into a single underlying construct. In addition, the systematic correlates of these measures identified by previous literature are not equivalent predictors of the different types of anxiety. Politics seems to be a source of apprehensiveness and worry that affects individuals who are not necessarily suffering from general anxiety.
THE GLOBAL CRISIS AND THE PSYCHOLOGICAL FEASIBILITY OF INTERNATIONALISM
Authors: Culp Julian 
Published: May 2024

AbstractThis essay revisits the metanormative version of the motivational critique of contemporary conceptions of cosmopolitan justice. I distinguish two ways of understanding this critique as leveling the charge of infeasibility against cosmopolitanism. Cosmopolitan motivation can be understood to be infeasible because it is impossible or because it is not reasonably likely to be achieved if tried. The possibilistic understanding is not persuasive, given that examples show that cosmopolitan motivation is possible. The conditional probabilistic understanding is more compelling, by contrast, because under certain social conditions it may not be reasonably likely that cosmopolitan motivation is achieved if tried. I argue, however, that whether cosmopolitan motivation is infeasible in the conditional probabilistic sense depends on malleable social conditions, given that, according to a plastic account of the human moral mind developed by Allen Buchanan, social conditions can undermine or favor the formation of cosmopolitan motivation. I illustrate this plastic account by showing how it can explain recent anticosmopolitan orientations as “tribalistic” reflexes to global crises, like the COVID-19 pandemic, which involved competition for survival resources and (existential) threats. I conclude that cosmopolitan motivation is not infeasible under all social conditions and that cosmopolitanism therefore requires bringing about and maintaining those social conditions under which cosmopolitan motivation is feasible.
MILITARY INTERVENTION IN INTERSTATE ARMED CONFLICTS
Authors: Fabre Cécile 
Published: May 2024

AbstractSuppose that state A attacks state D without warrant. The ensuing military conflict threatens international peace and security. State D (I assume) has a justification for defending itself by means of military force. Do third parties have a justification for intervening in that conflict by such means? To international public lawyers, the well-rehearsed and obvious answer is “yes.” Threats to international peace and security provide one of two exceptions to the legal and moral prohibition (as set out in Article 2[4] of the UN Charter) on using force as a means for resolving interstate disputes. Just war theorists are not as verdictive. Compared to the ethics of humanitarian intervention and the ethics of national self-defense, the ethics of third-party military involvement in interstate conflicts remains underdeveloped in contemporary just war theory. This essay begins to fill that gap. I argue that to defend such interventions is tantamount to defending preventive military force, deterrent military force, and the resort to force in more cases than standardly thought. I then provide an account and limited defense of the deterrence argument. I show that deterrence is morally justified in relatively few cases and examine two problems with the argument: deterrence failures and the level of uncertainty under which leaders who use deterrent force operate. I conclude that we should take seriously the possibility that nonintervention, construed as the rejection of the direct use of military force, is the morally correct response to the most serious threats to international peace and security.
CAN LIBERALISM LAST? DEMOGRAPHIC DEMISE AND THE FUTURE OF LIBERALISM
Authors: Anomaly Jonathan , Nobre Faria Filipe 
Published: May 2024

AbstractLiberal political institutions have been an enormous boon for humanity. The free market aspect of liberalism has led to an explosion of innovation, ranging from new kinds of technology and novel forms of entertainment to advances in science and medicine. The emphasis on individual rights at the core of liberalism has increased our ability to explore new ways of living and to construct an identity of our own choosing. But liberal political institutions around the world are facing two crises: low fertility and declining social trust. In particular, liberalism’s focus on individual liberty rather than group cohesion can increase economic productivity by encouraging the free movement of people and capital, but this movement is associated with declines in social cohesion and fertility. In this essay, we highlight some challenges to the long-term evolutionary stability of liberalism. In other words, we raise the question: Can liberalism last?
Are Archaeologists Talking About Looting? Reviewing Archaeological and Anthropological Conference Proceedings from 1899–2019
Authors: Oosterman Naomi , Tremain Cara Grace 
Published: May 2024

AbstractThe impetus for this study was a review of the Society for American Archaeology (SAA) 86th Annual Meeting program in 2021. Finding that no single poster or presentation referenced looting or antiquities trafficking despite these issues being ethical considerations that all SAA members are expected to recognize, we sought to investigate whether this was an irregularity – perhaps due to the virtual format of the meeting – or whether it was more common than not. For a broader understanding of if, how, and where these topics are discussed by archaeologists outside of the SAA, we expanded the investigation and studied the archives of 14 other archaeological and anthropological conferences. The results of the study show that despite there being an overall increase in mentioning looting and antiquities trafficking at conferences, it remains a niche and infrequently discussed topic.1
‘Healthier options tend to get lost in the noise of online’ – Australian shoppers’ experiences with online grocery platforms

Abstract

Objective:
We aimed to understand what influences parents’ purchasing behaviours when shopping for groceries online and potential ways to improve the healthiness of online grocery platforms.

Design:
We conducted semi-structured interviews, guided by the Marketing Mix framework. Reflexive thematic analysis was used to analyse data.

Setting:
Online interviews were conducted with primary grocery shoppers.

Participants:
Parents (n 14) or caregivers (n 2) using online grocery platforms at least every 2 weeks.

Results:
Most participants perceived purchasing healthy food when shopping for groceries online to be more challenging compared to in physical stores. They expressed concerns about the prominence of online marketing for unhealthy food. Participants from lower socio-economic backgrounds often depended on online supermarket catalogues to find price promotions, but healthy options at discounted prices were limited. Across socio-economic groups, fresh items like meat and fruit were preferred to be purchased instore due to concerns about online food quality.
Participants believed online grocery platforms should make healthy foods more affordable and supported regulations on supermarket retailers to promote healthy options and limit unhealthy food promotion online.

Conclusions:
Participants had varied experiences with online grocery shopping, with both positive and negative aspects. Efforts to improve population diets need to include mechanisms to create health-enabling online grocery retail platforms. Government interventions to restrict marketing of unhealthy foods and promote marketing of healthy options on these platforms warrant investigation.
