Published: May 2024

Abstract
Two major trends on children’s skills to comprehend metaphors have governed the literature on the subject: the literal stage hypothesis vs. the early birds hypothesis (Falkum, 2022). We aim to contribute to this debate by testing children’s capability to comprehend novel metaphors (‘X is a Y’) in Spanish with a child-friendly, picture selection task, while also tracking their gaze. Further, given recent findings on the development of metonymy comprehension suggesting a U-shaped developmental curve for this phenomenon (Köder & Falkum, 2020), we aimed to determine the shape of the developmental trajectory of novel metaphor comprehension, and to explore how both types of data (picture selection and gaze behavior) relate to each other. Our results suggest a linear developmental trajectory with 6-year-olds significantly succeeding in picture selection and consistently looking at the metaphorical target even after question onset.
Signal design and performance analysis for LEO high dynamic navigation application
Authors: Wang Lei , Che Jibin , Chen Haoyan 
Published: May 2024

AbstractWith the development of GNSS (Global Navigation Satellite System), LEO (Low Earth Orbit) systems are adopted to enhance the system performance of GNSS. The signal Doppler of the LEO satellite is seven to nine times that of GNSS signals, which benefits positioning performance but leads to high acquisition complexity. This paper proposes the combination of a CSS (Chirp Spread Spectrum) marker and the main body of traditional modulation methods for high dynamic application. The acquisition calculation complexity and mean acquisition time of the proposed signal are analysed and compared with the traditional signal. The result shows that the acquisition calculation complexity is just 26 % of the traditional signal under the parameters considered and the mean acquisition time of the proposed signal is also lower than the traditional signal. Hence, the proposed signal is able to decrease the mean acquisition time of the receiver under the constraint of calculation complexity and should be adopted for LEO high dynamic application.
An improved wide-lane ambiguity resolution method for kinematic smartphone positioning

Abstract
The release of GNSS raw data on Android smartphones provides the potential for high-precision smartphone positioning using multi-constellation and multi-frequency signals. However, severe multipath and low observation quality in kinematic environments make double-differenced uncombined ambiguities difficult to resolve reliably. To address this, the paper proposes an improved wide-lane (WL) integer ambiguity resolution (IAR) method that combines integer rounding and the Least-Square AMBiguity Decorrelation Adjustment (LAMBDA) methods. The proposed method achieved fix rates of 57% to 70% in challenging environments, with an average improvement of 7 · 7% in horizontal positioning accuracy compared to the float solution. The traditional partial integer rounding method only improved accuracy by 1 · 1%.
How to Be a ‘Good’ Collector: Some Ethical Reflections on the Private Collecting of Cultural Heritage
Authors: Scarre Geoffrey 
Published: May 2024

AbstractThis paper discusses some of the major ethical issues that arise in connection with the widespread holding of cultural heritage by private collectors. If, as many people believe, and UNESCO has affirmed, cultural heritage is, in some morally significant sense, everyone’s heritage, then the private acquisition of cultural heritage, although widely permitted in law, raises some significant ethical questions. I discuss the nature of the tension between public heritage and private ownership of heritage items and the possibility that more might be done by law to regulate the activities of private collectors before arguing the merits of a shift in the mindset of collectors from thinking of themselves as the unfettered owners of the heritage they acquire towards conceiving themselves primarily as stewards who protect and preserve that heritage on behalf of the wider community. There follows a detailed examination of practical ways in which collectors can discharge their stewardship role to the best effect, emphasizing, in particular, the fresh opportunities for doing so afforded to collectors by the new digital environment.

Abstract
In 2020, an outbreak of Salmonella Hadar illnesses was linked to contact with non-commercial, privately owned (backyard) poultry including live chickens, turkeys, and ducks, resulting in 848 illnesses. From late 2020 to 2021, this Salmonella Hadar strain caused an outbreak that was linked to ground turkey consumption. Core genome multilocus sequence typing (cgMLST) analysis determined that the Salmonella Hadar isolates detected during the outbreak linked to backyard poultry and the outbreak linked to ground turkey were closely related genetically (within 0–16 alleles). Epidemiological and traceback investigations were unable to determine how Salmonella Hadar detected in backyard poultry and ground turkey were linked, despite this genetic relatedness. Enhanced molecular characterization methods, such as analysis of the pangenome of Salmonella isolates, might be necessary to understand the relationship between these two outbreaks. Similarly, enhanced data collection during outbreak investigations and further research could potentially aid in determining whether these transmission vehicles are truly linked by a common source and what reservoirs exist across the poultry industries that allow Salmonella Hadar to persist. Further work combining epidemiological data collection, more detailed traceback information, and genomic analysis tools will be important for monitoring and investigating future enteric disease outbreaks.

Abstract
Nosocomial outbreak of varicella zoster virus (VZV) has been reported when susceptible individuals encounter a case of chicken pox or shingles. A suspected VZV outbreak was investigated in a 50-bedded in-patient facility of Physical Medicine and Rehabilitation in a tertiary care multispecialty hospital. A 30-year-old female patient admitted with Pott’s spine was clinically diagnosed with chicken pox on 31 December 2022. The following week, four more cases were identified in the same ward. All cases were diagnosed as laboratory-confirmed varicella zoster infection by PCR. Primary case was a housekeeping staff who was clinically diagnosed with chicken pox 3 weeks prior (9 December 2022). He returned to work on eighth day of infection (17 December 2022) after apparent clinical recovery but before the lesions had crusted over. Thirty-one HCWs were identified as contacts a and three had no evidence of immunity. Two of these susceptible HCWs had onset of chickenpox shortly after first dose of VZV vaccination was inoculated. All cases recovered after treatment with no reported complications. VZV infection is highly contagious in healthcare settings with susceptible populations. Prompt identification of cases and implementation of infection prevention and control measures like patient isolation and vaccination are essential for the containment of outbreaks.

Abstract
The COVID-19 pandemic modified the epidemiology and the transmission of respiratory syncytial virus (RSV). We collected data on RSV positivity and incidence from children hospitalized in the largest tertiary paediatric hospital in Greece before (2018–2020, period A), during (2020–2021, period B), and after (2021–2023, period C) the COVID-19 lockdown. A total of 9,508 children were tested for RSV. RSV positivity (%) was 17.6% (552/3,134) for period A, 2.1% (13/629) for period B, and 13.4% (772/5,745) for period C (p < 0.001). The mean age (±SD) of RSV-positive children among the three periods was A: 5.9(±9.3), B: 13.6 (±25.3), and C: 16.7 (±28.6) months (p < 0.001). The peak of RSV epidemiology was shifted from January–March (period A) to October–December (period C). RSV in-hospital incidence per 1,000 hospitalizations in paediatric departments was A:16.7, B:1.0, and C:28.1 (p < 0.001), and the incidence in the intensive care unit was A: 17.3, B: 0.6, and C: 26.6 (p < 0.001). A decrease in RSV incidence was observed during the COVID-19 lockdown period, whereas a significant increase was observed after the lockdown. A change in epidemiological patterns was identified after the end of the lockdown, with an earlier seasonal peak and an age shift of increased RSV incidence in older children.
Rainbow Hamiltonicity in uniformly coloured perturbed digraphs

Published: May 2024

AbstractWe investigate the existence of a rainbow Hamilton cycle in a uniformly edge-coloured randomly perturbed digraph. We show that for every
$\delta \in (0,1)$
there exists
$C = C(\delta ) \gt 0$
such that the following holds. Let
$D_0$
be an
$n$
-vertex digraph with minimum semidegree at least
$\delta n$
and suppose that each edge of the union of
$D_0$
with a copy of the random digraph
$\mathbf{D}(n,C/n)$
on the same vertex set gets a colour in
$[n]$
independently and uniformly at random. Then, with high probability,
$D_0 \cup \mathbf{D}(n,C/n)$
has a rainbow directed Hamilton cycle.This improves a result of Aigner-Horev and Hefetz ((2021) SIAM J. Discrete Math.35(3) 1569–1577), who proved the same in the undirected setting when the edges are coloured uniformly in a set of
$(1 + \varepsilon )n$
colours.

Published: May 2024

SummaryTesticular biopsies (9 mm3) from domestic cats (n = 10) submitted to orchiectomy were submitted to equilibrium vitrification in the presence of ethylene glycol (EG) alone or combined with dimethylsulfoxide (DMSO) as intracellular cryoprotectants, and sucrose or trehalose as extracellular cryoprotectants. The samples were vitrified with 40% EG or 20% EG + 20% DMSO, plus 0.1 M or 0.5 M of sucrose or trehalose. The study was divided into Step 1 and Step 2. In Step 1, intratubular cells (spermatogonia, spermatids, spermatocytes, and Sertoli cells) were quantified and classified as intact or degenerated (pyknotic and/or vacuolated cells). Cryodamage of seminiferous cords was determined by spermatogonia and Sertoli cell scoring of nuclei alterations, tubular basement membrane detachment, epithelium shrinkage, and tubular measures (total area, epithelium area, larger and smaller diameter, and height of the epithelium). In Step 2, Hoechst 33342 stain and propidium iodide (PI) fluorescent stain were used to assess the cell viability of the four best experimental groups in Step 1. The effect of treatments on all analyses was accessed using analysis of variance (ANOVA), and Fisher’s post hoc test at P < 0.05 significance was considered. In Step 1, the mean percentage of spermatogonia and Sertoli cells morphological integrity did not show a difference when using both sugars at different concentrations, but their morphology was more affected when DMSO was used. EG use associated with 0.1 M of sucrose or trehalose positively affected spermatocyte and spermatid morphology, respectively. The larger diameter and epithelium height of seminiferous tubules were increased using DMSO plus 0.5 M sucrose and DMSO plus 0.1 M trehalose. The changes in spermatogonial/Sertoli nucleoli visualization were best scored in the EG groups, while the nuclei condensation was lower with sucrose. The basement membrane was satisfactorily preserved with 0.1 M sucrose. In Step 2, the percentage of cell viability was higher when EG plus 0.1 M sucrose was used. Therefore, DMSO’s negative effect on the vitrification of testicular biopsies of adult domestic cats was evident. The EG plus 0.1 M of sucrose or trehalose associations are the most suitable CPAs to preserve the testicular histology structure of adult domestic cats in vitrification.

Published: May 2024

SummaryMaternal intermittent fasting (MIF) can have significant effects on several tissue and organ systems of the body, but there is a lack of research on the effects on the reproductive system. So, the aim of our study was to analyze the effects of MIF on fertility. B6C3F1Crl (C57BL/6N × C3H/HeN) male and female mice were selected for the first part of the experiments and were analyzed for body weight and fat weight after administration of the MIF intervention, followed by analysis of sperm counts and activation and embryo numbers. Subsequently, two strains of mice, C57BL/6NCrl and BALB/cJRj, were selected and administered MIF to observe the presence or absence of vaginal plugs for the purposes of mating success, sperm and oocyte quality, pregnancy outcome, fertility status and in vitro fertilization (IVF). Our results showed a significant reduction in body weight and fat content in mice receiving MIF intervention in B6C3F1Crl mice. Comparing the reproduction of the two strains of mice. However, the number of litters was increased in all MIF interventions in C57BL/6NCrl, but not statistically significant. In BALB/cJRj, there was a significant increase in the number of pregnant females as well as litter size in the MIF treatment group, as well as vaginal plugs, and IVF. There was also an increase in sperm activation and embryo number and the MIF intervention significantly increased sperm count and activation. Our results suggest that MIF interventions may be beneficial for reproduction in mice.
Against all odds: successful pregnancy in an adult patient with unrepaired coarctation of the aorta
Authors: Sorice Davide , Barracano Rosaria , Sarubbi Berardo 
Published: May 2024

AbstractAccording to the modified World Health Organization classification, pregnant women with unrepaired aortic coarctation are at very high risk for both maternal and fetal complications and should, therefore, be counselled against pregnancy. The most frequent maternal complications include systemic hypertension, renal failure, preeclampsia, and aortic dissection. Herein, we describe a successful pregnancy in an adult patient with unrepaired aortic coarctation.
What Is It to Be Responsible for What You Say?
Authors: Borg Emma 
Published: May 2024

AbstractIn asserting something I incur certain kinds of liabilities, including a responsibility for the truth of the content I express. If I say ‘After leaving the EU, the UK will take back control of c. £350 million per week’, or I tell you that ‘The number 14 bus stops at the British Museum’, I become liable for the truth of these claims. As my audience, you could hold me unreliable or devious if it turns out that what I said is false. Yet this socio-linguistic practice – of acquiring and ascribing ‘linguistic liability’ – is complicated, especially given philosophical distinctions between the various different kinds of contents people can express (am I liable, for instance, for the claim that the number 14 bus stops at the British Museum today or only usually?). This paper explores the different kinds of contents speakers might be taken to express, arguing that our practices around linguistic liability (including in legal disputes) reveal a crucial role for a notion of context-independent, literal meaning attaching to words and sentences. These practices thus vindicate what philosophers tend to term ‘minimal semantic content’.
On Discussing What We Should Do
Authors: Heal Jane 
Published: May 2024

AbstractMany of the good things which make human life worthwhile are essentially social, cannot be enjoyed by one person unless they are enjoyed together with others. And it is obvious that thinking in terms of the first-person plural, we/us, plays a large part in everyday life as people consider puzzlements (‘What should we do?’) and remark on the success of what they decided on (‘That worked out really well for us!’). Analytic philosophers should accept this at face value, recognising that human beings are often co-subjects with each other, that there is irreducible plural intentionality. The paper explores how the existence of plural intentionality manifests itself in our concepts and ways of proceeding and how attempted ‘analysis’ of what goes on as the assemblage of many interlocking instances of singular intentionality distorts and misleads.
Games, Norms, and Utterances
Authors: Popa-Wyatt Mihaela , Wyatt Jeremy L. 
Published: May 2024

AbstractA body of work proposes that social-norm change can be explained in terms of game theory. These game theoretic models, however, don't fully account for how and why utterances are used to change social norms. This paper describes the problem and some of the solution elements. There are three existing, relevant, game-based models. The first is a game theoretic model of social norm change (Bicchieri, 2005, 2016). This accounts for how individuals make decisions to adhere to or violate norms, based on empirical expectations of how others will behave. The second is the idea of a conversational game (Lewis, 1979) and its extensions. This posits that speech acts are accommodated in a conversation to make what is said correct play. This feature can explain how some speech acts, such as slurring utterances, change the dynamics of a conversation. The third is a theory of pragmatic inference, known as Rational Speech Act theory (Goodman and Frank, 2016). This is a computational theory of pragmatics, of how listeners interpret utterances and how speakers construct utterances that can be understood. This paper proposes, without setting out the full formal model, that elements of these three theories need to be incorporated together into a game theoretic model of how utterances change long-term social norms.
Prejudicial Speech: What's a Liberal to Do?
Authors: Mikkola Mari 
Published: May 2024

AbstractThis paper discusses potential responses to harmful prejudicial speech. More specifically, it considers how different types of prejudicial speech merit different responses. The paper distinguishes hate speech, discriminatory speech, and toxic speech as different types of speech that are prejudicial or oppressive – they are not of the same kind diverging only in their severity and explicitness. As these sorts of problematic speech are categorially distinct, the paper holds, they also demand differential remedies. The task of this paper is to consider such remedies, their potential effectiveness, and compatibility with the liberal value of free speech.
Stories and Selves: A Twisted Love Story about the Meaning of Life
Authors: Camp Elisabeth 
Published: May 2024

AbstractI argue that stories are ‘equipment for living’ in two senses: retrospectively, they provide ‘configurational comprehension’ of a temporal sequence of events; prospectively, they offer templates for action. Narrative conceptions of the self appear well poised to leverage these functional roles for stories into an intuitively compelling view of self-construction as self-construal. However, the narrative conception defines selves in terms of the lives they live: a self is the protagonist in a lifelong story. And narrative structure is itself defined by ‘retrospective necessity’: the meaning of events within a story is given by their contribution to that story's ending. Together, this entails that life stories hold selves metaphysically, epistemically, and practically hostage to their ends. Fortunately, narratives are just one species of interpretive frame. I suggest some alternative types of frames, including identity labels and metaphors, that support configurational comprehension, action guidance, and self construction without shackling selves to their lives’ ends.
Dignity-related distress and recall among alert, non-delirious critically ill patients
Authors: Hadler Rachel A. , Weeks Seth , He Yifan , Fraer Mony , Dexter Franklin 
Published: May 2024

AbstractObjectivesCritical illness is associated with multiple undesired impacts, including residual psychological distress, frequently associated with recollections of critical illness. Dignity-related distress is highly prevalent among the one-fifth of critically ill patients who are alert. The distress may be associated with unpleasant recollections of care. We examined whether patients at risk for dignity-related distress had recall of their reported distress approximately 1 week after assessment and whether this recall differed from another high-risk group, specifically patients undergoing dialysis for end-stage renal disease.MethodsThe prospective cohort study included patients with critical illness and patients with end-stage renal disease enrolled from intensive care units (ICUs) and dialysis units at 1 academic center. Distress was assessed using the Patient Dignity Inventory (PDI). Participants received in-patient or telephonic follow-up 7–10 days after the initial interaction. Follow-up encounters focused on recollection of key aspects of the interpersonal interaction as well as the content of the PDI.ResultsA total of 32 critically ill patients participated in initial assessment and follow-up. In total, 26 dialysis patients participated in both phases. The groups’ demographics differed. Fifty percent (n = 16) of critically ill patients and 58% (n = 15) of dialysis patients reported a mean score per item of >1.6, corresponding with severe distress on the PDI. Among the ICU patients, the 95% upper 2-sided confidence interval for the median level of recall was commensurate with the participant having had no recall of the initial interview beyond remembering that there was an interview. The end-stage renal disease group did not demonstrate significantly better recall.Significance of resultsDignity-related distress is high in both critically ill patients and those with end-stage renal disease; however, recollection of assessment is poor in both groups. Any intervention designed to mitigate dignity-related distress will need either to be immediately deployable or not to be reliant upon recollection for impact.
