From measurement to classificatory practice: improving psychiatric classification independently of the opposition between symptom-based and causal approaches
Authors: Basso Alessandra 
Published: November 2021

AbstractThe article advances a new way of thinking about classifications in general and the classification of mental disorders in particular. By applying insights from measurement practice to the context of classification, I defend a notion of epistemic accuracy that allows one to evaluate and improve classifications by comparing different classifying methods to each other. Progress in classification arises from the mutual development of classification systems and classifying methods. Based on this notion of accuracy, the article illustrates with an example how psychiatric classifications can be improved via circumscribed comparisons of different perspectives on mental disorders, without relying on complete models of their complex aetiology. When applying this strategy, the traditional opposition between symptom-based and causal approaches is of little consequence for making progress in the epistemic accuracy of psychiatric classification.
Comments on fixed point results in classes of function with values in a b–metric space
Authors: Brzdęk Janusz 
Published: November 2021

AbstractWe prove and discuss several fixed point results for nonlinear operators, acting on some classes of functions with values in a b-metric space. Thus we generalize and extend a recent theorem of Dung and Hang (J Math Anal Appl 462:131–147, 2018), motivated by several outcomes in Ulam type stability. As a simple consequence we obtain, in particular, that approximate (in some sense) eigenvalues of some linear operators, acting in some function spaces, must be eigenvalues while approximate eigenvectors are close to eigenvectors with the same eigenvalue. Our results also provide some natural generalizations and extensions of the classical Banach Contraction Principle.
Comprehensive study of the wet and dry spells and their extremes in the Mediterranean climate basin Northern Tunisia

Abstract
Abstract
In agriculture, the characterization of dry spells is essential whether it is to calibrate the water needs of crops or the flow rates of rivers. This study seeks to develop a discretization of dry and wet spells on a monthly scale while evaluating the risk of extremes using the renewal wet-dry spell model. This model consists of defining the wet spell according a negligible precipitation threshold. The structure of the model is that all parameters of the climate cycle, including its length, are random variables. To study the trend of the parameters we use the Mann–Kendall test, while the magnitude is evaluated by the Sen’s estimation method. The approach is applied to Ichkeul Lake basin in northern Tunisia to demonstrate its capacity. This region is of great agricultural and water importance, although it holds six large dams. The results show that the duration of the dry and wet spells reach’s, respectively, 49 days and 17 days. The maximum dry spell was 49 days in 1982. The Mann–Kendall test revealed three stations with significant positive trend of the monthly extreme dry spell length (at March) located in south and east of the basin. The trend analysis of the seasonal rainfall number showed one station with significant negative trend in east and one station with significant negative trend in the center of the basin. Results indicated that no significant changes in the start and end of rainy season have occurred over the past years. But a great relation with a subsequent length exists. The results of this research assist farmers and managers in establishing drought management plans. It allow, among other things, to calibrate simulation models for a more realistic management of water reservoirs. It also makes it possible to plan irrigations on a more different basis from that of observations made at regular time intervals.

Highlights

We analyze the trends of the drought in Ichkeul lake basin, Northern Tunisia, characterized from the daily rainfall data of five stations. The alternating wet-dry spell model and a precipitation threshold value are used to define the rainfall/dry event. The Mann–Kendall test and the Sen’s estimation method were used to analyze the possible trends and the magnitude of variables analyzed, respectively.

The results show an increasing trend of maximum monthly dry spells. No significant changes in the start and end of rainy season have occurred over the past years.

These analyses provide useful information for science and society and make it possible to minimize unexpected damage due to long dry spells and to have effective and efficient planning for various stakeholders.
Interrupted time-series analysis to evaluate the impact of a behavioral change outpatient antibiotic stewardship intervention
Authors: Morgan Brittany L. , Bettencourt Haylee , May Larissa 
Published: November 2021

Abstract

Objective:
We evaluated the effect of a behaviorally enhanced quality improvement intervention in reducing the number of antibiotic prescriptions written for antibiotic nonresponsive acute respiratory infections (ARIs). A secondary objective was identifying whether a reduction in inappropriate antibiotic prescriptions, if present, persisted after the immediate implementation of the intervention.

Design:
Nonrandomized, quasi-experimental study conducted from January 2017 through February 2020.

Setting:
University of California, Davis Health outpatient clinics. In total, 21 pediatric, family, and internal medicine practices in 10 cities and towns were included.

Patients:
Patients evaluated by a participating physician at an enrolled practice site during the study period with diagnoses (primary and secondary) from the International Classification of Diseases, Tenth Revision codes consistent with antibiotic nonresponsive ARI diagnoses.

Intervention:
A behaviorally enhanced quality improvement intervention to reduce inappropriate prescribing for antibiotic nonresponsive ARI.

Results:
In total, 63,028 eligible patient visits across 21 locations were included in the analysis. The most frequently prescribed antibiotic for antibiotic nonresponsive ARI was azithromycin (n = 3,551), followed by amoxicillin (n = 924). Overall, the intervention was associated with an immediate 46% reduction in antibiotic prescriptions for antibiotic nonresponsive ARI (P = .001) following the intervention. We detected no significant change in the month-to-month trend after the intervention was implemented (P = .87), indicating that the reduction was sustained throughout the postintervention period.

Conclusion:
Our findings demonstrate that a behaviorally enhanced quality improvement intervention to reduce inappropriate prescribing for antibiotic nonresponsive ARI in ambulatory care encounters was successful in reducing potentially inappropriate prescriptions for presumed antibiotic nonresponsive ARI.
Constitutional Design of Electoral Governance in Federal States
Authors: Pal Michael 
Published: November 2021

AbstractThis article explores the constitutional politics of electoral governance in federations by focusing on the role of election commissions, drawing mainly on examples from Asia. All democracies face the challenge of insulating electoral governance from interference and capture. Compared to unitary states, federations confront the additional dilemma of how to disperse authority over electoral governance across multiple orders of government. Federal democracies must decide whether electoral governance should be a matter for the center or the states. I argue that the basic choice is between what I will call the ‘unitary model’ and the ‘division of powers model.’ The main institution of electoral governance is the electoral management body or ‘EMB.’ In the unitary model, a central EMB administers both national and state-level elections. In the ‘division of powers model’, both a central and state-level EMBs exist, with the state commissions administering elections in the component units of the federation. In federal democracies generally, but especially in Asia, the allure of the unitary model has been strong. The article draws on the example of the Constituent Assembly in India to illustrate what is at stake in how federal constitutions allocate authority over electoral governance.

AbstractLarge-amplitude electromagnetic radiofrequency fields are created by the charge-separation induced in interactions of high-intensity, short-pulse lasers with solid targets and have intensity that decreases with the distance from the target. Alternatively, it was experimentally proved very recently that charged particles emitted by petawatt laser–target interactions can be deposited on a capacitor-collector structure, far away from the target, and lead to the rapid (nanosecond-scale) generation of large quasi-static electric fields ($\mathrm{MV}/\mathrm{m}$), over wide regions. We demonstrate here the generation of both these fields in experiments at the PHELIX laser facility, with approximately$20\;\mathrm{J}$energy and approximately${10}^{19}\;\mathrm{W}/\mathrm{c}{\mathrm{m}}^2$intensity, for picoseconds laser pulses, interacting with pre-ionized polymer foams of near critical density. Quasi-static fields, up to tens of kV/m, were here observed at distances larger than$1\;\mathrm{m}$from the target, with results much higher than the radiofrequency component. This is of primary importance for inertial-confinement fusion and laser–plasma acceleration and also for promising applications in different scenarios.

AbstractBarriers are commonly installed in workplace situations where physical distancing cannot be maintained, but their effectiveness in decreasing viral transmission is unknown. In simulations, physical barriers with no openings were effective in reducing contamination with an aerosolized benign virus or fluorescent microspheres, but barriers with openings were not.
THE LONG-TERM EFFECTS OF STATE REPRESSION ON POLITICAL BEHAVIOR AND ATTITUDES: EVIDENCE FROM TAIWAN
Authors: Chiou Fang-Yi , Hong Ji Yeon 
Published: November 2021

AbstractThis article examines how violence against citizens affects their political attitudes and behavior in the long run, and how those effects vary over time. We construct and analyze a novel dataset on the victims of Taiwan's February 28 Incident, in 1947, with survey data spanning 1990 to 2017. Our empirical analysis shows that cohorts having directly or indirectly experienced the Incident are less likely to support the Kuomintang Party (KMT), the former authoritarian ruling party responsible for the Incident. They tend to disagree with the key conventional policy stand of the KMT (unification with mainland China), are more likely to self-identify as Taiwanese, and are less likely to vote for KMT presidential candidates. Taiwan's residents who were born in towns with larger number of casualties during the Incident are more likely to reject unification. Finally, the effects are found to vary over the period following democratization.
Size-driven preservational and macroecological biases in the latest Maastrichtian terrestrial vertebrate assemblages of North America

Published: November 2021

AbstractThe end-Cretaceous (K/Pg) mass extinction event is the most recent and well-understood of the “big five” and triggered establishment of modern terrestrial ecosystem structure. Despite the depth of research into this event, our knowledge of upper Maastrichtian terrestrial deposits globally relies primarily on assemblage-level data limited to a few well-sampled formations in North America, the Hell Creek and Lance Formations. These assemblages disproportionally affect our interpretations of this important interval. Multiple investigations have quantified diversity patterns within these assemblages, but the potential effect of formation-level size-dependent taphonomic biases and their implications on extinction dynamics remains unexplored. Here, the relationship between taphonomy and body size of the Hell Creek Formation and Lance Formation dinosaurs and mammals are quantitatively analyzed. Small-bodied dinosaur taxa (<70 kg) are consistently less complete, unlikely to be articulated, and delayed in their description relative to their large-bodied counterparts. Family-level abundance (particularly skeletons) is strongly tied to body mass, and the relative abundance of juveniles of large-bodied taxa similarly is underrepresented. Mammals show similar but nonsignificant trends. The results are remarkably similar to those from the Campanian-aged Dinosaur Park Formation, suggesting a widespread strong taphonomic bias against the preservation of small taxa, which will result in their seemingly depauperate diversity within the assemblage. This taphonomically skewed view of diversity and abundance of small-bodied taxa amid our best late Maastrichtian samples has significant implications for understanding speciation and extinction dynamics (e.g., size-dependent extinction selectivity) across the K/Pg boundary.
Why Bother? Supporters of Locally Weaker Parties Are Less Likely to Vote or to Vote Sincerely
Authors: Cutler Fred , Rivard Alexandre , Hodgson Antony 
Published: November 2021

AbstractVoters are deterred from casting a vote and more likely to vote strategically if their preferred choice is less competitive in their electoral district. We use 2019 Canadian Election Study data to show that respondents’ answers to a “how likely are you to vote” question depend on their estimate of their preferred party's local chances of winning, relative to other parties. This deterrent effect on turnout from the competitiveness of a voter's preferred party is concentrated among certain parties (NDP, Green, People's Party of Canada). Under first-past-the-post (FPTP), voters with particular policy perspectives are systematically deterred from voting, relative to other voters. Furthermore, we find that despite supporters of all parties having an incentive to vote strategically if their party is outside the top two in the district, strategic voting is heavily concentrated among voters who prefer parties other than the nationally most competitive two parties.
THE RETURN OF THE PIPERS: IN SEARCH OF NARRATIVE MODELS FOR THEAITIONOF THEQVINQVATRVS MINVSCVLAE
Authors: Wysłucha Kamila 
Published: November 2021

AbstractThe article argues that the famous story about the strike, exile and return of the Romanaulosplayers, which is recorded in the sixth book of Ovid'sFastiand referred to by other Latin and Greek sources, is based on a narrative model that already existed in Greece in the Archaic period. The study draws parallels between the tale of the pipers and the myth of the return of Hephaestus to Olympus, suggesting that, apart from similar plots, the two stories share many motifs, such as references to themes derived from comedy and satyr drama. Searching for a possible channel of transmission of the story from Archaic Greece to Augustan Rome, the study explores the presence of satyric motifs in Etruscan vase-painting and Roman processional rites. It is furthermore emphasized that many of these motifs, which also appeared in lost satyr-plays, are echoed in Augustan poetry.
Geochemistry of the Laiyang Group from outcrops and Lingke-1 core on Lingshan Island, Shandong Province, Eastern China: implications for provenance, tectonic setting and palaeo-environment

Published: November 2021

AbstractLower Cretaceous sedimentary rocks of Lingshan Island, located along the continental margin of East Asia, have received increased attention. The Lingke-1 core mainly belongs to the Lower Cretaceous Laiyang Group. We investigate provenance, tectonic setting, palaeoclimate and palaeoredox conditions in the study area using elemental geochemistry, thereby elucidating the depositional history of the Lower Cretaceous sediments and reconstructing the palaeo-environment. To achieve this, 90 siltstones and 76 mudstones were sampled from this core and other outcrops on Lingshan Island. The chemical index of alternation (CIA) values for the majority of the samples and the bivariate diagrams indicate that the sedimentary rocks were subjected to minor weathering processes. Geochemical results suggest that source rocks for the region are felsic igneous and metamorphic rocks, along with minor proportions of intermediate igneous rocks. Major- and trace-element discrimination diagrams, deciphering the tectonic history, indicate that source rocks mainly originated from the continental island-arc and active continental margin. Several representative geochemical indices and the bivariate plots based on elemental contents show that the Laiyang Group was predominantly deposited in arid conditions. Sr/Ba values suggest a palaeosalinity transition from brackish to saline, demonstrating a depositional transformation from lacustrine facies for the lower Laiyang Group to marine facies in the upper Laiyang Group. U/Th and V/(V+Ni) ratios and Ce anomalies in the rocks indicate anoxic conditions. We conclude that the conspicuous decline in the trends of the above three geochemical indices, ranging between 400 and 800 m, may be related to the latest Hauterivian oceanic anoxic event.

Published: November 2021

AbstractThe evolution and resulting morphology of a contourite drift system in the SE Pacific oceanic basin is investigated in detail using seismic imaging and an age-calibrated borehole section. The Nazca Drift System covers an area of 204 500 km2and stands above the abyssal basins of Peru and Chile. The drift is spread along the Nazca Ridge in water depths between 2090 and 5330 m. The Nazca Drift System was drilled at Ocean Drilling Program Site 1237. This deep-water drift overlies faulted oceanic crust and onlaps associated volcanic highs. Its thickness ranges from 104 to 375 m. The seismic sheet facies observed are associated with bottom current processes. The main lithologies are pelagic carbonates reflecting the distal position relative to South America and water depth above the carbonate compensation depth during Oligocene time. The Nazca Drift System developed under the influence of bottom currents sourced from the Circumpolar Deep Water and Pacific Central Water, and is the largest yet identified abyssal drift system of the Pacific Ocean, ranking third in all abyssal contourite drift systems globally. Subduction since late Miocene time and the excess of sediments and water associated with the Nazca Drift System may have contributed to the Andean orogeny and associated metallogenesis. The Nazca Drift System records the evolution in interactions between deep-sea currents and the eastward motion of the Nazca Plate through erosive surfaces and sediment remobilization.
Dividend Smoothing and Firm Valuation
Authors: Brockman Paul , Hanousek Jan , Tresl Jiri , Unlu Emre 
Published: November 2021

AbstractWe examine the relationship between dividend smoothing and firm valuation across 21 countries using several empirical methods and smoothing measures. Our main results show that dividends are capitalized at significantly larger values for high-smoothing firms than for low-smoothing firms. We also find that dividend-smoothing premiums are higher in countries with weak shareholder protection – suggesting that smoothing serves as a substitute mechanism to reduce agency costs. Overall, our findings support the view that managers use dividend smoothing predominantly as a bonding mechanism to reduce agency costs (Leary and Michaely (2011)), and not as a rent extraction mechanism (Lambrecht and Myers (2012)).
The Role of the Discount Rate in Investment and Employment Decisions
Authors: Møller Stig Vinther , Priestley Richard 
Published: November 2021

AbstractTime variation in the discount rate affects investment and employment decisions in a manner consistent with Q-theory predictions. This evidence is uncovered when using cyclical consumption as a proxy for the discount rate. The results, which are consistent across both U.S. and international data, suggest that firms respond rationally to variations in the cost of capital and that the discount rate has a substantial impact on macroeconomic dynamics and hence business cycle fluctuations.

Published: November 2021

AbstractBackgroundThe aetiology and significance of internal carotid artery variations at the skull base remain controversial after decades, with limited available literature. Approximately 10–40 per cent of the general population has parapharyngeal internal carotid artery variations.MethodA prospective observational study was conducted on internal carotid artery variations in 36 cadavers, in a tertiary care hospital, between March 2019 to March 2020.ResultsThe most common internal carotid artery variation observed in the specimens was tortuosity, in 30 per cent, followed by kinking in 18 per cent and coiling in 10 per cent. Thirty per cent of specimens had variations present bilaterally. A loop pattern of the internal carotid artery was identified. Coiling of the internal carotid artery may present as a node; hence, meticulous dissection is advocated near the skull base to avoid complications. These variations hold utmost importance for otorhinolaryngologists performing pharyngeal and nasopharyngeal surgical procedures.ConclusionA detailed knowledge of anatomy, along with its variations, and surgical expertise, will help reduce the incidence of surgical complications.
Doing and feeling together in older age: self-worth and belonging through social creative activities

Published: November 2021

AbstractThe potential for art activities to help in alleviating loneliness is explored through a focus on older women's regular attendance at creative social activities. We apply the concept of perceived emotional synchrony to understand how weekly craft group sessions enable feelings of belonging and self-worth to develop in older women. Using a multi-site six-month study of 62 women aged 70+ attending social creative activities, our multi-stage research design captures the experiences of these women through observation and narrative group discussions held weekly. Our findings show that feelings of belonging and self-worth developed over a relatively short time. In particular, social integration and identity fusion were found to occur as a result of the emotional synchrony engendered via a regular shared activity, out of the home, and requiring some challenge and creativity. We propose a virtuous cycle model to explain the value in such activities and discuss the wider implications for wellbeing in older age. Perceived emotional synchrony has not been used before to explore the mechanisms through which social creative activities form lasting benefits for older women. Our research highlights the importance of feeling at one with others in improving feelings of belonging and self-worth and indicates how a variety of social creative experiences could be designed to enable this.
