The Impact of Sleep-Wake Behaviour on Tennis Match Performance in Junior State Grade Tennis Players
Authors: Turner Mitchell , Beranek Philipp , Dunican Ian C. , Cruickshank Travis 
Published: September 2022

Abstract
Purpose
To date, no study has investigated the extent to which sleep-wake behaviour (SWB) influences match performance in junior tennis players. This study aimed to assess the influence of SWB for the week and night before on match performance, particularly match analytics and activity.

Methods
This study recruited 10 junior state grade tennis players who wore an actigraphy device and completed a sleep diary for the week before their match on two separate occasions throughout their competition season. Players wore a global positioning system device to track their movement during matches, and an experienced tennis coach recorded players' match analytics.

Results
This study showed that the sleep fragmentation index was significantly lower the week before matches in females who had won than those who had lost. Additionally, the sleep fragmentation index was significantly lower the night before a given match than the week before. Only sleep fragmentation index and sleep latency significantly influenced match performance in junior tennis players. The percentage of second serves points won differed between match wins and losses for male players, while winners and forced errors differed for female players.

Conclusion
These findings provide a detailed profile of tennis match play in junior state grade players. Despite individual differences, reduced restlessness the night before a match coincides with increased match performance.
Jus Cogens: Redux
Authors: Sellers Patricia Viseur 
Published: September 2022

In The Boundaries of International Law: A Feminist Critique (Boundaries),1 amidst observations about masculine bias in treaty law, co-authors Christine Chinkin and Hilary Charlesworth queried the masculine configuration, i.e., the gender of jus cogens or peremptory norms. A peremptory norm is “accepted and recognized by the international community . . . as a norm from which no derogation is permitted and which can be modified only by a subsequent norm of international law having the same character.”2 Interrogating whether jus cogens privileged the experiences of males over that of females, they challenged jus cogens’ presumed universality and its intended utility. Accepted peremptory norms, they averred, exerted a silencing, deleterious impact on core feminine values such as sexual equality or freedom from gender discrimination.3 Decades after the Vienna Convention on the Law of Treaties’ (VCLT) codification of jus cogens, the International Law Commission (ILC) reified a non-exhaustive list of peremptory norms that explicitly excluded gender-based discrimination.4 This essay proposes a “jus cogens redux” to revive Chinkin and Charlesworth's question by peering at several threads in the thwarted conversations about whether freedom from gender discrimination rises to peremptory norm status. The conversational threads lay tattered by positive law's reliance on enumerated treaty provisions and accepted precepts of customary international law. They are frayed by normative law's philosophical, moralists’ approach. Neither the positivist law nor the normative law's concepts of how to determine jus cogens values grapples with gender or gender minorities. By default, each retains a masculine approach that configures the gender of jus cogens as “non-female.”
AN INCOMPLETENESS THEOREM VIA ORDINAL ANALYSIS
Authors: WALSH JAMES 
Published: September 2022

AbstractWe present an analogue of Gödel’s second incompleteness theorem for systems of second-order arithmetic. Whereas Gödel showed that sufficiently strong theories that are
$\Pi ^0_1$
-sound and
$\Sigma ^0_1$
-definable do not prove their own
$\Pi ^0_1$
-soundness, we prove that sufficiently strong theories that are
$\Pi ^1_1$
-sound and
$\Sigma ^1_1$
-definable do not prove their own
$\Pi ^1_1$
-soundness. Our proof does not involve the construction of a self-referential sentence but rather relies on ordinal analysis.

The evolution of the medical record from paper to digital: an ENT perspective
Authors: Murphy C , Keogh I J 
Published: September 2022

AbstractObjectivesA national electronic health record is being procured for Health Service Executive hospitals in Ireland. A number of hospitals have implemented an electronic document management system. This study aimed to investigate the efficiency and safety of the electronic document management system in our centre.MethodsA retrospective audit was performed of patients operated on at Galway University Hospital. The availability and location of patients’ admission data on the electronic document management system were recorded. These data were analysed using Microsoft Excel software, version 16.45.ResultsThe records of 100 patients were analysed. The main findings were: 5 per cent of operation notes were missing, 80 per cent were in the incorrect section, while 15 per cent were in the correct ‘procedure’ section on the electronic document management system.ConclusionThis study shows there is potential for error with ‘paper-light’ solutions, whereby delayed scanning, misfiling of scanned records and missing records may lead to significant delays in treatment and potential patient safety issues.
Functional and structural brain differences in bipolar disorder: a multimodal meta-analysis of neuroimaging studies
Authors: Chen Guanmao , Wang Junjing , Gong Jiaying , Qi Zhangzhang , Fu Siying , Tang Guixian , Chen Pan , Huang Li , Wang Ying 
Published: September 2022

AbstractBackgroundNumerous studies of resting-state functional imaging and voxel-based morphometry (VBM) have revealed differences in specific brain regions of patients with bipolar disorder (BD), but the results have been inconsistent.MethodsA whole-brain voxel-wise meta-analysis was conducted on resting-state functional imaging and VBM studies that compared differences between patients with BD and healthy controls using Seed-baseddMapping with Permutation of Subject Images software.ResultsA systematic literature search identified 51 functional imaging studies (1842 BD and 2190 controls) and 83 VBM studies (2790 BD and 3690 controls). Overall, patients with BD displayed increased resting-state functional activity in the left middle frontal gyrus, right inferior frontal gyrus (IFG) extending to the right insula, right superior frontal gyrus and bilateral striatum, as well as decreased resting-state functional activity in the left middle temporal gyrus extending to the left superior temporal gyrus and post-central gyrus, left cerebellum, and bilateral precuneus. The meta-analysis of VBM showed that patients with BD displayed decreased VBM in the right IFG extending to the right insula, temporal pole and superior temporal gyrus, left superior temporal gyrus extending to the left insula, temporal pole, and IFG, anterior cingulate cortex, left superior frontal gyrus (medial prefrontal cortex), left thalamus, and right fusiform gyrus.ConclusionsThe multimodal meta-analyses suggested that BD showed similar patterns of aberrant brain activity and structure in the insula extending to the temporal cortex, fronto-striatal-thalamic, and default-mode network regions, which provide useful insights for understanding the underlying pathophysiology of BD.
Legitimating collaboration, collaborating to legitimate: Justification work in “holistic” services for long-term unemployed persons
Authors: HANSEN MAGNUS PAULSEN , CHRISTENSEN SIGNE ELMER , TRIANTAFILLOU PETER 
Published: September 2022

AbstractTo address complex social problems, such as long-term unemployment, local authorities in many countries are developing “holistic” or “integrated” services, where multiple actors and professions collaborate with a view to better meet the needs of the individual citizen. By breaking with existing practices and regulations, collaborative services must be legitimized in new ways so as to appear acceptable not only in the eyes of the public and politicians, but also to caseworkers and the long-term unemployed persons. This article examines the multifarious and sometimes neglected efforts to make these collaborative services legitimate in the eyes of this plurality of stakeholders on multiple levels of governance. Our study indicates three distinct but mutually interrelated spheres of audience that require partly conflicting justification work. We also find that the narrow pursuit of justification work to ensure legitimacy with one audience may potentially jeopardize the justification work in the other two.
“I no longer count in German.” On dominance shift in returnee heritage speakers
Authors: Flores Cristina , Zhou Chao , Eira Carina 
Published: September 2022

AbstractThis study analyzes the degree of language balance in three groups of bilingual speakers of Portuguese and German: a group of Portuguese heritage speakers (HSs) living in Germany, another who returned to Portugal, and Portuguese late learners of German L2. Based on the DIALANG vocabulary size placement test, applied in German and in Portuguese, and on extralinguistic variables extracted from a background questionnaire, the results confirm high degrees of unbalanced language dominance favoring the societal language (SL) in HSs without the experience of return, and a leveling of language dominance in returnees. Language balance in returnees is the consequence of some loss of proficiency in the former SL (German) and reactivation of the heritage language (Portuguese). Current relative amount of contact with the two languages is correlated with language dominance only in the HSs and the late L2 speaker groups, whereas age of return and length of residence in Portugal explain language dominance in returnees. Self-reported proficiency is also predictive of language dominance and may be taken as complementary indicator.
RECONSTRUCTING OFFICIAL STATISTICS: A NEW ESTIMATE OF THE ARGENTINE COST OF LIVING INDEX, 1912-1943
Authors: Lanata-Briones Cecilia T. 
Published: September 2022

ABSTRACTThis paper produces a new estimate of the Argentine cost of living index (COLI) for the period 1912-1943 that amends the oversights of the official series. The lack of an appropriate splice when the shares of the index's components are changed explains the divergence between the official and the Reconstructed COLIs. The 17.3 percentage-point gap for the period 1912-1943 between the official series used by the historiography and the Reconstructed COLI accounts for the oversights of the official estimate. This divergence is also evidenced when generating real wages. Hence, when Juan Domingo Perón arrived at the National Labour Department in 1943, all else being equal, workers of the City of Buenos Aires were worse off economically than the historiography assumes.
The Practice and Politics of Establishment
Authors: Fittall William 
Published: September 2022

The following words were spoken in the House of Commons 23 years ago:
Many people in this country think that it is wrong to have an established Church and that it would be helpful if England followed the example of Scotland and Wales and disestablished its Church, recognising that we are a multicultural, multi-faith society and that no religion or Church should be given pre-eminence over others. Would it not be prudent for the Church Commissioners to do their sums now so that when that democratic day dawns, it will not be such a shock for them?
Well, what can one say about that other than, ‘O, Jeremy Corbyn!’? For it was indeed the then maverick Labour backbencher who made those remarks during Church Commissioners’ questions in the House of Commons.
Transcatheter retrieval of atrial septal defect and patent ductus arteriosus occluder: a guidance for device retrieval based on comprehensive bench tests

Published: September 2022

AbstractObjectives:The aim of this study is to establish a guidance for device retrieval based on comprehensive bench tests.Background:Device embolisation remains a major complication in transcatheter closure of atrial septal defect and patent ductus arteriosus. Although percutaneous retrieval is feasible in the majority of cases, surgical retrieval may be required in complicated circumstances. However, the methods of transcatheter device retrieval have not been completely established.Methods:Bench tests of device retrieval were performed to verify the appropriate retrieval method according to device type/size. The devices used for testing were Amplatzer Septal Occluder (Abbott, Chicago, IL, United States of America), Figulla Flex II (Occlutech GmbH, Jena, Germany), Amplatzer Duct Occluder-I (Abbott), Amplatzer Duct Occluder-II (Abbott), and Amplatzer Vascular Plug-II (Abbott). The retrieval equipment constituted diagnostic catheters (multipurpose catheter and right Judkins catheter, 4-Fr or 5-Fr, Gadelius Medical, Tokyo, Japan), delivery sheath and cables for each device, Amplatz goose neck snares (Medtronic, Minneapolis, MN, United States of America), OSYPKA CATCHER (Osypka ag, Rheinfelden-Herten, Germany), and OSYPKA LASSOS (Osypka). We investigated the retrieval equipment and sheath sizes required for a successful retrieval procedure for variously sized devices.Results:For patent ductus arteriosus devices, the type of snare and the snaring position are considered important. For atrial septal defect devices, simple snare capture or a double-snare technique with a sufficiently large sheath is effective. Special care should be taken when using the OSYPKA CATCHER for device retrieval.Conclusions:The results of this study may assist in the selection of both capture devices and a retrieval sheath or a catheter for complete retrieval.
The extreme southern origins of globality: Circumnavigation, habitability, and geopolitics
Authors: Onetto Pavez Mauricio 
Published: September 2022

AbstractThis article analyses how the first circumnavigation of the world, from 1519 to 1522, introduced South America as a key space in the formation of the ‘global’, thus producing a historical point of inflection. We examine the commercial and political plans and networks that began to function as a result of this new connectivity, which turned the American continent into a major global axis. The analysis focuses on the way in which this voyage gave new prominence to an unexplored region of the world, namely the southernmost tip of America, thus changing the notion of habitability that had prevailed for centuries in Europe. These changes questioned the authority of ‘ancient’ Greek thinkers and strengthened a European historical narrative that appropriated the discovered territories and distinguished the extreme southern part of America from other southern regions, as symbolized through figures such as the Patagonian giants. I consider these changes based on evidence from Spanish sources.
Vergleich unterschiedlicher Instrumente zur Messung von Gesundheitskompetenz im Zusammenhang mit Lesekompetenz und kognitiven Fähigkeiten von Jugendlichen
Authors: Seifert Susanne , Maitz Katharina , Pendl Dominik , Gasteiger-Klicpera Barbara 
Published: September 2022

Zusammenfassung. Instrumente zur Messung von Gesundheitskompetenz bei Jugendlichen basieren auf sehr heterogenen Definitionen und Konzepten. Zudem können sie grundsätzlich in subjektive (Selbsteinschätzungs–) und objektive (die Performanz messende) Verfahren unterteilt werden. In der vorliegenden Studie wurden 2 subjektive (eHEALS; Kurzform des HLS-EU-Q16) und ein objektives Messinstrument (Claim) von 471 Jugendlichen der 6. und 7. Klassenstufe (Durchschnittsalter 13.04 Jahre; 49 % Mädchen; 63 % Familiensprache Deutsch) bearbeitet und auf ihren wechselseitigen Zusammenhang, den Zusammenhang mit kognitiven und Lesefähigkeiten, sowie Unterschiede in Bezug auf Geschlecht und Familiensprache untersucht. Das objektive Verfahren korrelierte nicht mit den subjektiven Verfahren. Dies bestätigt die Annahme, dass sie aufgrund der Messperspektive unterschiedliche Indikatorenausprägungen von Gesundheitskompetenz erfassen. Korrelationen mit Lese- und kognitiven Fähigkeiten zeigten sich nur beim objektiven Instrument, wohingegen die Selbsteinschätzungsinstrumente diese Aspekte der Gesundheitskompetenz nicht abbilden. Unterschiede hinsichtlich des Geschlechts und der Familiensprache zeigten sich insbesondere beim objektiven Instrument, allerdings sind Antwortverzerrungen bei Selbsteinschätzungen möglich. Die spezifischen Vor- und Nachteile von subjektiven und objektiven Verfahren sollten bei der Instrumentenauswahl berücksichtigt werden.
The Earth‐Observing Aqua Satellite Mission: 20 Years and Counting
Authors: Parkinson Claire L. 
Published: September 2022

AbstractThe Earth‐observing Aqua spacecraft was launched on 4 May 2002 and has now completed 20 years of collecting and transmitting data regarding the Earth's radiation budget, atmosphere, oceans, land, and ice. Although launched with a design life of 6 years, four of its instruments continue to operate and provide high‐quality data streams more than 20 years after launch. The Aqua data are readily available to users worldwide and have been used in thousands of scientific publications and in numerous practical applications, including weather forecasting, air‐quality assessments, and monitoring of forest fires, dust storms, volcanic ash plumes, oil spills, and crop yields.

Published: September 2022

AbstractA new incoherent scatter radar (ISR) has recently been dedicated at Sanya (SYISR), China (geographic 18.34°N and 109.62°E) to detect the low‐latitude ionospheric plasma by conducting continuous operation and electronic beam steering on a pulse‐to‐pulse basis. This paper provides an overview of the processing procedure of SYISR ion line data and presents some preliminary observational results under various transmitting signal schemes and different working modes, such as the zenith‐directed mode and meridional and zonal scanning modes, with comparison to the international reference ionosphere model (IRI‐2016), ionosonde and Ionospheric Connections Explorer (ICON) satellite measurements. The diurnal and altitude versus latitude variation characteristics of electron density (Ne), electron temperature (Te), and ion temperature (Ti) are in accordance with those of other ISR measurements in mid‐low latitudes, and IRI shows some discrepancies with SYISR observations, including the sunrise and sunset enhancement in SYISR_Ti and the overestimated IRI_Te. The comparison between the daytime SYISR_Ti and ICON_Ti shows good consistency based on 31 observational samples. The measurement of line‐of‐sight velocity (Vi) for long pulse can reveal the properties of the medium scale traveling ionospheric disturbances manifesting the radar's potential to study the mesoscale ionospheric variation in the Sanya area. The derived vector velocities with a better measurement accuracy during the day are generally in line with ionospheric plasma physics. The results show that SYISR can obtain continuous ionospheric parameters through multi‐beam scanning measurements at ∼700 km horizontal scale, which provides important information for studying the atmosphere‐ionosphere‐magnetosphere coupling and ionospheric scintillation at low latitudes in East Asia.
Landsat data commercialized
Authors: Anonymous  
Published: September 2022

Data for about 600,000 Landsat scenes—all those acquired by multispectral scanners (MSS) aboard Landsat satellites more than 2 years ago—are now available from the Earth Resources Observation Systems (EROS) Data Center (EDC) in Sioux Falls, S. Dak., at reduced prices. Landsat images are valuable for planning, change detection, and monitoring of Earth resources and environment and provide unique information about land conditions and changes during the 1970s and 1980s that is not available from other sources. The availability of the data are expected to benefit substantially the study of global climate change as an early indicator of climate change and as a contributor to changes in the chemical composition of the atmosphere.An agreement was recently signed between the National Oceanic and Atmospheric Administration and the Earth Observation Satellite, whereby MSS data more than 2 years old will be distributed through both EOSAT and the U.S. Geological Survey. EOSAT retains exclusive sales rights to MSS data less than 2 years old.
Radar and telegraph each developed by pulsing
Authors: Court Arnold 
Published: September 2022

Radar's development during the 1930s, as sketched by R. D. Hill (“Origins of Radar,” Eos, July 3, 1990) strongly paralleled that of the electric telegraph a century earlier. For each, basic feasibility (signal reflection for radar, current transmission for telegraph) had been demonstrated many years earlier in various parts of Europe and America, but practical application awaited pulsing. For radar, this required emission and timing of returns (echos) of pulses shorter than their travel times; telegraphy required the development of an alphabet based on groups of pulses of two or more differing durations.After Bishop Watson's transmission of a Leyden jar discharge through 2 miles of wire near London in 1747, a multiwire scheme for signaling letters was published in 1774 but was never implemented (A. P. Deschenel, Popular Science Monthly, August 1873). At Geneva in 1784, Lesage used 24 wires, one for each letter; by 1837, Professor Steinheil in Vienna sent letters formed “by different combinations of two elementary signals.”
