Efficient parameter estimation for parabolic SPDEs based on a log-linear model for realized volatilities
Authors: Bibinger Markus , Bossert Patrick 
Published: February 2023

AbstractWe construct estimators for the parameters of a parabolic SPDE with one spatial dimension based on discrete observations of a solution in time and space on a bounded domain. We establish central limit theorems for a high-frequency asymptotic regime. The asymptotic variances are shown to be substantially smaller compared to existing estimation methods. Moreover, asymptotic confidence intervals are directly feasible. Our approach builds upon realized volatilities and their asymptotic illustration as a response of a log-linear model with spatial explanatory variable. This yields efficient estimators based on realized volatilities with optimal rates of convergence and minimal variances. We demonstrate efficiency gains compared to previous estimation methods numerically and in Monte Carlo simulations.

Introduction Point-of-care ultrasound (POCUS) is utilized in austere environments because it is lightweight, durable, battery powered, and portable. In austere settings, weight and space constraints are limitations to carrying dedicated ultrasound gel. Few studies have assessed commonly carried liquids as gel alternatives. The study objective was to assess the suitability of common food and personal care products as ultrasound coupling agents compared with that of commercial gel. Methods A noninferiority study compared 9 products to commercial gel. Each substance was independently tested on 2 subjects by 2 sonographers covering 8 standardized ultrasound windows. Clips were recorded, blinded, and independently graded by 2 ultrasound fellowship-trained physicians on the ability to make clinical decisions and technical details, including contrast, resolution, and artifact. A 20% noninferiority margin was set, which correlates to levels considered to be of reliably sufficient quality by American College of Emergency Physicians’ guidelines. The substances included water, soap, shampoo, olive oil, energy gel, maple syrup, hand sanitizer, sunscreen, and lotion. Results A total of 300 of 318 (94%) clips met the primary endpoint of adequacy to make a clinical decision. All media, except sunscreen, were noninferior to commercial gel in the ability to make a clinical decision (α=0.05). In terms of secondary outcomes, resolution, artifact, and contrast, all substances were noninferior to commercial gel (α=0.05). The sonographers concluded that all gel alternatives’ usability performed similarly to commercial gel, with the exception of energy gel. Conclusions Of the 9 substances tested, 8 were noninferior to commercial gels for clinical decisions. Our study indicates that several POCUS gel substitutes are serviceable to produce clinically adequate images.

Published: February 2023

AbstractIntolerance of uncertainty (IU) is a cognitive bias that leads to perception and intolerance of uncertainty and has associated negative cognitive, emotional, and behavioural responses. It plays a strong role in social anxiety disorder (SAD; Counsell et al., 2017). Our experimental study examined the impact of uncertainty related to a social stressor on SAD using a speech task. We examined features of SAD including anticipatory anxiety, anxiety during the task, willingness to perform the task, and avoidance of the task. Undergraduate students (N = 110, 88% female) with significant social anxiety completed a series of questionnaires, then were randomised to one of two conditions related to level of uncertainty about an impromptu speech task. The experimental condition (state IU) did not predict any of the outcome variables, while trait IU significantly predicted anxiety levels. Results indicate that increased uncertainty of a social situation does not impact acute anxiety levels in SAD and reinforce the strong role of trait IU as a transdiagnostic cognitive variable. Neither trait nor state IU predicted the willingness and avoidance variables. Results also highlighted the central role of the experience of anxiety on avoidance behaviours, above cognitive factors such as IU.
Probabilistic Truth, Relativism, and Objective Chance
Authors: Schimmelpfennig Svenja 
Published: February 2023

AbstractIn Probabilistic Knowledge Sarah Moss proposes that our credences and subjective probability judgments (SPJs) can constitute knowledge. Mossean probabilistic knowledge is grounded in probabilistic beliefs that are justified, true, and unGettiered. In this paper I aim to address and solve two challenges that arise in the vicinity of the factivity condition for probabilistic knowledge: the factivity challenge and the challenge from probabilistic arguments from ignorance (probabilistic AIs). I argue that while Moss's deflationary solution to the factivity challenge formally works, it leaves us ill-equipped to handle probabilistic AIs. An account of probabilistic knowledge that cannot overcome probabilistic AIs makes knowledge of thoroughly probabilistic contents a rare and unstable phenomenon, at best, or, at worst, impossible. I hold that establishing a metaphysically enriched account of probabilistic truth is therefore mandatory. I go on to develop a truth-conditional approach on probabilistic factivity that is relativistic in its nature and centers on objective chances. I show that while the approach is still compatible with Moss's overall semantics for probabilistic knowledge, it provides us with a simple but forceful answer to probabilistic AIs.
The Work of Retirement
Authors: Sklansky Jeffrey 
Published: February 2023

AbstractIn the past few decades, caregivers, such as nursing assistants and home health aides, have come to compose the fastest-growing segment of the paid workforce in the United States. At the same time, corporate caretakers of workers’ savings, such as pension funds and mutual funds, have become the nation's largest investors, bound by fiduciary duties of trust. And unprecedented numbers of elder employees and retirees have become the biggest supposed beneficiaries of both care labor and trust capital, depending on health workers and asset managers in their daily lives. At the center of this emerging structure of work, wealth, and welfare lies the pension system, a telling crucible of class relations in our time. Several recent books across different disciplines examine the shifting politics of pensions in the United States and around the world. The spate of new studies presents an opportunity to explore the remarkable role of retirement funds in reorganizing labor and finance over the past fifty years. Rather than offering a historiographical critique of current work, this expository essay surveys the main findings of a larger and longer body of scholarship on organized labor and investment related to pensions. Though focused on the United States, it places the American story in a comparative context. The survey points to a fertile field for further study: as retirees have increasingly relied on professional asset managers and caregivers, the finance and health sectors have undergone converging crises over fiduciary duty and elder care, posing parallel challenges for organized labor.

Published: February 2023

AbstractThis study was conducted to determine the effect of acidophilus yoghurt (yoghurt fortified with Lactobacillus acidophilus) in comparison to traditional plain yoghurt (St. thermophilus and L. bulgaricus starter cultures) on the survival of three pathogenic Escherichia coli strains; Shiga toxigenic O157 (STx O157), non-toxigenic O157 (Non-STx O157) and Shiga toxigenic non-O157 (STx O145). After six days of refrigerated storage of laboratory-manufactured yoghurt inoculated with the three strains of E. coli separately, all were eliminated in acidophilus yoghurt, while their survival extended in the traditional yoghurt along the storage period (17 d). Reduction percentages of the tested strains in acidophilus yoghurt were 99.93, 99.93 and 99.86%, with log reduction of 3.176, 3.176, and 2.865 cfu/g for Stx O157, Non-Stx O157, and Stx O145 E. coli, respectively, in comparison to 91.67, 93.33 and 93.33%, with log reduction of 1.079, 1.176 and 1.176 cfu/g in traditional yoghurt. Statistical analysis showed a significant effect of acidophilus yoghurt in reducing the count of Stx E. coli O157 (P = 0.001), Non-Stx E. coli O157 (P < 0.01) and Stx E. coli O145 (P < 0.01) compared to the traditional yoghurt. These findings emphasize the potential use of acidophilus yoghurt as a biocontrol alternative method for eliminating pathogenic E. coli, as well as other similar applications in the dairy industry.

Published: February 2023

AbstractCambodian waters historically supported significant nesting populations of marine turtles up to the early 20th century. However, although fishing and coastal development have intensified, marine turtle conservation has received little recent attention. We collate the available information on Cambodian marine turtles by summarizing NGO and government data from provincial consultations, fisheries surveys and nesting beach surveys, and synthesize our findings into recommendations for the conservation of marine turtles in Cambodia. The available data indicate that a small and highly threatened marine turtle population persists, despite significant declines driven by intense historical harvesting, widespread bycatch, loss of nesting habitat, marine wildlife trade and ongoing poor compliance with wildlife protection regulations. To improve the conservation status of Cambodian turtles, we recommend (1) revising relevant legislation to better protect marine turtle habitats whilst increasing compliance with gear restrictions and threatened species laws in priority sites, (2) trialling alternative fishing gear or gear modifications to reduce bycatch, (3) continuing capacity building for locally driven marine turtle conservation science, (4) identifying and mapping beaches with high nesting potential and protecting them from further coastal development, and (5) investing in transboundary collaborations to improve the monitoring and management of the turtle populations that range between Cambodia and neighbouring countries.
Neglecting the care of people with schizophrenia: here we go again
Authors: Pelosi Anthony J. , Arulnathan Vijay 
Published: February 2023

AbstractSpecialist early intervention teams consider clinician–patient engagement and continuity of care to be a driving philosophy behind the treatment they provide to people who have developed schizophrenia or a related psychotic illness. In almost all countries where this service model has been implemented there is a dearth of available data about what is happening to patients following time-limited treatment. Information on discharge pathways in England indicates that some early intervention specialists are discharging most of their patients from all psychiatric services after only 2 or 3 years of input. Some ex-patients will be living in a state of torment and neglect due to an untreated psychosis. In the UK, general practitioners should refuse to accept these discharge pathways for patients with insight-impairing mental illnesses.
Null-homotopic knots have Property R

AbstractWe prove that if K is a nontrivial null-homotopic knot in a closed oriented 3–manfiold Y such that
$Y-K$
does not have an
$S^1\times S^2$
summand, then the zero surgery on K does not have an
$S^1\times S^2$
summand. This generalises a result of Hom and Lidman, who proved the case when Y is an irreducible rational homology sphere.
National climate litigation and the international rule of law
Authors: Buser Andreas 
Published: February 2023

AbstractThis article assesses the implications of national climate litigation for what is termed ‘the international rule of law’. Starting from the finding that the current international climate treaty regime lacks several elements of an international rule of law, such as legal bindingness, clarity, and justiciability, the author explores what national courts contribute to filling these gaps. Deviating from a linear progression narrative, which is prevalent in existing literature, this article provides a more nuanced and complex picture. Whereas successful climate litigation is hardly imaginable without reliance on internationally agreed-upon facts – such as reports by the Intergovernmental Panel on Climate Change and global average temperature levels deemed ‘dangerous’ – doctrinally decisions do not represent a turn toward a stricter rule of international climate law. Instead of applying and progressively developing climate treaties, courts thus far have primarily used these provisions only to develop national constitutional law and regional human rights law. The created system of highly contextual national rule(s) of climate law is a fragmented one which is regionally limited to a few states predominantly located in Western Europe. Consequently, it is a far cry from a truly global rule of international climate law.

Summary
Species reintroductions can be used in conservation management to increase biodiversity and aid in restoring ecosystem function. For reintroductions to be successful, it is important to identify the conditions required to establish a viable population. We developed a demographic model using Vortex10, an individual-based simulation software, to assess the long-term consequences of different management interventions on the success of the recent reintroduction of the white stork, Ciconia ciconia, to the UK. Demographic data obtained from this reintroduced population were supplemented with information from western European populations to build the models. The impact of incorporating different management actions (e.g. supplementing with captive-bred juveniles, provision of nesting platforms, and habitat improvement/supplementary feeding) on the stochastic population growth rate was assessed. Survival rates also differ depending on an individual’s migratory strategy, hence we tested the impact of having different proportions of the population as residents or migrants. Our models showed that if the British stork population adopts a fully migratory strategy, with its associated higher mortality rates, i.e. all individuals migrating to southern Europe or northern Africa, increasing the supplementation rate would not lead to a positive population growth rate. However, management actions which increased the number of fledglings per nest generated a slight positive growth rate that led to a 54.3% increase in population size after 50 years and, when combining all three management options, the population grew by 378.3%. Alternatively, if a minimum of 9% of individuals overwintered in Britain, which is likely based on field observations and tracking data, a positive growth rate can be achieved without additional management due to this behaviour’s lower mortality rates. We conclude that the British white stork population will likely be viable in the long term, but these models and projections should be updated as more demographic data on this novel population become available.

AbstractIntroduction:The extrication from rubble is particularly critical for the survival of the victims of an earthquake. Early repeated infusion of sedative agents (SAs) in the acute trauma phase may interfere with neural processes leading to posttraumatic stress disorder (PTSD).Study Objective:This study aimed to analyze the psychological status reported by the buried victims of the earthquake in Amatrice (August 24, 2016; Italy) by considering type of the SAs administered during the extrication maneuvers.Methods:This was an observational study on data from 51 patients directly rescued under the rubble during the earthquake in Amatrice. During extrication maneuvers, a moderate sedation was administered by titrating ketamine (0.3-0.5mg/kg) or morphine (0.1-0.15mg/kg) with respect to the Richmond Agitation and Sedation Scale (RASS; between -2 and -3) in buried victims.Three years following the rescue, the survivors were interviewed on their perceived health status and stress using a questionnaire which consisted of 17 items: the standard four-item set of healthy days core questions (CDC HRQOL-4); the 12-item General Health Questionnaire (GHQ-12); and in addition, survivors were asked if they had a diagnosis for anxiety, depression, or for PTSD.Results:The study analyzed data from the complete clinical documentation of 51 survivors; 30 were males and 21 females, with an average age of 52 years. Twenty-six (26) subjects were treated with ketamine, while 25 were treated with morphine, during the extrication procedures. Concerning the quality-of-life analysis, only 10 survivors out of 51 perceived their health status as good; the others reported psychological disorders. The GHQ-12 scores showed that all survivors had psychological distress with a mean total score of 22.2 (SD = 3.5). Eighteen (18) victims declared to have had a diagnosis of generalized anxiety (35%), while 29 were treated for depression (57%) and PTSD (57%) by a specialist. With regards to the perceived distress level and the anxiety disorder, this analysis showed significant associations with SAs used during extrication, with a better performance for ketamine than for morphine.Conclusion:These findings suggest investigating whether early sedation with ketamine directly in the disaster setting may promote the prophylaxis and reduce the risk of developing trauma-related disorders (TRDs) on the buried victims of major natural disasters in future studies.
The association between cannabis use and subjective memory complaints in older adults in the United States

Published: February 2023

AbstractObjective:The U.S. population is aging and increasing numbers of older adults are using cannabis. Cognitive decline is common in older age and subjective memory complaints (SMC) have been associated with increased risk for dementia. While residual cognitive effects of cannabis use at younger ages are well understood, the links between cannabis use and cognition in older adults is less clear. The present study represents the first population-level analysis of cannabis use and SMC in older adults in the U.S.Method:We used the National Survey of Drug Use and Health (NSDUH) dataset to evaluate SMC in respondents over age 50 (N = 26,399) according to past-year cannabis use.Results:Results revealed that 13.2% (95%CI: 11.5%−15.0%) of those who reported cannabis use also reported SMC, compared to 6.4% (95%CI: 6.1%–6.8%) among individuals with no cannabis use. Logistic regression revealed a two-fold increase (OR = 2.21, 95%CI: 1.88–2.60) of reporting SMC in respondents who had used cannabis in the past year, which was attenuated (OR = 1.38, 95%CI: 1.10–1.72) when controlling for additional factors. Other covariates, including physical health conditions, misuse of other substances, and mental illness also significantly contributed to SMC outcomes.Conclusions:Cannabis use represents a modifiable lifestyle factor that has potential for both risk and protective properties that may impact the trajectory of cognitive decline in older age. These hypothesis generating results are important for characterizing and contextualizing population-level trends related to cannabis use and SMC in older adults.
Poetry as history: Maulana Muhammad Anwar Shopiani and the Ahl-i Hadith movement in Kashmir
Authors: Yaseen Suvaid 
Published: February 2023

AbstractThe Ahl-i Hadith in South Asia has largely been studied as a textualist, puritan movement as a result of its exclusive emphasis on the Quran, Hadith sources, and connection with a variety of radical political and armed groups. In contrast, poetry has largely been associated with Sufi movements. This article questions this distinction and makes a historiographical intervention by examining the poetry of Maulana Muhammad Anwar Shopiani (d. 1940) in the Kashmiri, Persian, and Urdu languages. Through a close analysis of Shopiani's biography and poetry, the article complicates the hitherto available picture of the Ahl-i Hadith movement which Shopiani helped to take root in Kashmir. Doing so draws attention to the movement's novel literary aspect that engages with regional Sufi and sympathetic Hanafi thinking as well as with the broader Persianate literary traditions and transregional currents of revivalist thinking on the basis of the principle of taḥqīq, research. Even as Shopiani's message remains committed to a ‘factual’ iteration based upon Quran and Hadith sources, it is the concept of love, both in its spiritual and worldly manifestations, that emerges as central to his thought. It is through this that the paradox between the actual historical distance from Prophet Muhammad's time and the Ahl-i Hadith's ideological desire to revive that time by a literal enactment of the sunnah is resolved. In doing so, the article makes a methodological case for employing poetry as a source for writing an intellectual history from below which examines Islamic movements on their own terms.
