Classroom‐based Oral Storytelling: Reading, Writing, and Social Benefits
Authors: Spencer Trina D. , Pierce Chelsea 
Published: September 2022

AbstractMany students struggle to acquire adequate reading comprehension and writing skills. Although word recognition and spelling are needed to fully actualize these skills, the oral language aspects of reading and writing can be taught and practiced without text. Oral storytelling is good for all students, but it may be essential for students with code‐related disabilities and students with limited proficiency in the mainstream academic language of U.S. schools. The purpose of this article is to offer oral storytelling as a versatile classroom‐based approach for advancing diverse students' reading and writing skills, as well as facilitating their social–emotional development. Based on an extensive theoretical and empirical literature, we propose seven strategies teachers can implement to infuse oral storytelling in their classrooms.
Induction
Authors: Ben-Ari Mordechai 
Published: September 2022

AbstractThe axiom of mathematical induction is used extensively as a method of proof in mathematics. This chapter presents inductive proofs of results that may not be known to the reader. We begin with a short review of mathematical induction (Sect. 6.1). Section 6.2 proves results about the familiar Fibonacci numbers while Sect. 6.3 proves results about Fermat numbers. Section 6.4 presents the 91-function discovered by John McCarthy; the proof is by induction on an unusual sequence: integers in an inverse ordering. The proof of the formula for the Josephus problem (Sect. 6.5) is also unusual because of the double induction on two different parts of an expression.

, either continuous or discrete. We develop a Morse-type theory, the Conley–Floer homology, which captures travelling front solutions in a topologically robust manner, by encoding fronts in the boundary operator of a chain complex. The equations describing the travelling fronts involve both forward and backward delay terms, possibly of infinite range. Consequently, these equations lack a natural phase space, so that classic dynamical systems tools are not at our disposal. We therefore develop, from scratch, a general transversality theory, and a classification of bounded solutions, in the absence of a phase space. In various cases the resulting Conley–Floer homology can be interpreted as a homological Conley index for multivalued vector fields. Using the Conley–Floer homology, we derive existence and multiplicity results on travelling front solutions.

Zusammenfassung
Hintergrund
Patienten mit systemischen Autoimmun- und/oder autoinflammatorischen Erkrankungen (AI/AInf) bedürfen in der Regel einer multidisziplinären Zusammenarbeit durch verschiedene Fachrichtungen.

Ziel der Arbeit (Fragestellung)
Wir evaluierten, ob die Etablierung eines multidisziplinären Boards (sog. Rheumaboard [RB]) zur Optimierung der Versorgung von Patienten mit Psoriasisarthritis (PsA) oder anderen AI/AInf führt.

Material und Methoden
Es wurden n = 272 Patienten mit AI/AInf eingeschlossen, die in 3 Gruppen eingeteilt wurden; Gruppe 1: 41 Patienten mit oder mit Verdacht auf (V. a.) PsA, von der Dermatologie in der Rheumatologie konsiliarisch avisiert; Gruppe 2: 166 Patienten mit oder mit V. a. PsA, vorstellig in der Dermatologie und im RB; Gruppe 3: 65 Patienten mit anderen AI/AInf, vorstellig in der Dermatologie und im RB. Evaluiert wurde die durchschnittliche Zeit von der initialen Vorstellung bis zur Therapieeinleitung nach erfolgter Beurteilung und Diagnostik durch beide Fachrichtungen. Darüber hinaus wurden die Diagnosesicherung/-bestätigung und die Therapieweiterführung/-optimierung bei allen 3 Gruppen analysiert.

Ergebnisse
Die durchschnittliche Zeitspanne von der initialen Vorstellung bis zur Therapieeinleitung betrug in Gruppe 1 85 ± 42,24 (5 bis 173) Tage, in Gruppe 2 15 ± 13,09 (0 bis 78) Tage und in Gruppe 3 20 ± 16,71 (1 bis 75) Tage. In Gruppe 2 und 3 konnte die Diagnose schneller gesichert oder bestätigt sowie die Wartezeit auf Diagnostik und Therapie deutlich reduziert werden.

Diskussion
Durch die Etablierung eines RB zeigt sich eine signifikante Verkürzung der Zeitspanne zwischen Erstvorstellung und Therapieeinleitung und damit eine deutliche Verbesserung des Versorgungsmanagements bei Patienten mit AI/AInf inklusive Diagnosesicherung und Therapieoptimierung.

Moderating effect of carbon accounting systems on strategy and carbon performance: a CDP analysis
Authors: Bui Binh , Houqe Muhammad Nurul , Zahir-ul-Hassan Muhammad Kaleem 
Published: September 2022

AbstractCarbon emissions bring significant risks and opportunities, and organisations have responded by adopting different strategies and environmental control systems, such as carbon accounting systems (CASs). However, it remains unclear whether a CAS can help reduce emissions, and what role is played by a CAS in the relationship between carbon strategy and carbon performance. Therefore, this paper analyses the strategy-accounting-performance nexus by drawing on 1672 firm-year observations of firms participating in the CDP in 2014 and 2015. The results suggest that the quality of a CAS is influenced by strategic choices; with a proactive carbon strategy being associated with a higher quality CAS. Further, proactive strategies and CASs are found to be associated with carbon savings and emissions reduction. The results indicate a moderating role of CASs on the strategy-performance relationship, with carbon strategy enabling higher carbon savings and lower emissions intensity in the presence of a high-quality CAS. Our findings suggest that formulation of carbon strategies and establishment of carbon measures can drive effective carbon mitigation.

AbstractBackgroundPreoperative anxiety is associated with increased use of anesthetics and poorer postoperative outcomes. However, the prevalence of preoperative anxiety has not been characterized in Chinese patients. In this study, we aimed to estimate the overall prevalence of preoperative anxiety in Chinese adult patients and to explore the sociodemographic and clinical factors associated with preoperative anxiety in China.MethodsThis study was a multicenter cross‐sectional study conducted at 32 tertiary referral centers in China from September 1 to October 31, 2020. Adult patients scheduled for elective surgery were evaluated by the 7‐item Perioperative Anxiety Scale (PAS‐7) for preoperative anxiety after entrance to the operating zone.ResultsA total of 5191 patients were recruited, and 5018 of them were analyzed. The prevalence of preoperative anxiety measured by PAS‐7 was 15.8% (95% CI 14.8 to 16.9%). Multivariable analyses showed female sex, younger age, non‐retired, first in a lifetime surgery, surgery of higher risk, and poorer preoperative sleep were associated with higher prevalence of preoperative anxiety.ConclusionsPreoperative anxiety was relatively common (prevalence of 15.8%) among adult Chinese patients undergoing elective surgeries. Further studies are needed using suitable assessment tools to better characterize preoperative anxiety, and additional focus should be placed on perioperative education and intervention, especially in primary hospitals.Trial registrationThis study was registered prospectively at www.chictr.org.cn (ChiCTR1900027639) on November 22, 2019.

Published: September 2022

AbstractClimate models are vital to the assessment of the impacts of climate change in the Central African regions. Establishing how well models reproduce key processes is important to the confidence we attach to these tools. This study examines model representation of the September to November characteristics, such as location and intensity, of the African Easterly Jet (AEJ) north and south in a sample of 16 commonly evaluated CMIP5 and CMIP6 models and in two reanalyses (ERA5 and MERRA2). The analysis evolves to assess key drivers of the AEJ from energetic interactions, the characteristics of mid-level highs and thermal lows and the nature of surface thermal heating. Over West Africa, several models miss the southeast-northwest orientation of the AEJ-N core, leading to a gap of around 60 in the location of the jet while most CMIP5 models also fail to locate AEJ-S over southern Central Africa. In general, the spread of simulated AEJ locations around reanalyses is larger for the CMIP5 sample compared to CMIP6 equivalent models, indicating improvement from CMIP5 to CMIP6 in this 16 model subset. However, this improvement in some CMIP6 models (e.g. GISS-E2-1-G and MIROC6) is not related to a maximum surface meridional gradient in temperature. Most CMIP5 and CMIP6 models underestimate the surface temperature gradient over AEJ-N region. As a first order diagnostic of the jet's acceleration, most coupled models better simulate the atmospheric energetic interactions over AEJ-N region that leads to its strong contribution to AEJ-N maintenance compared to AEJ-S. This study strengthens our understanding of the mid-level circulation over Central Africa by detecting gaps in the mechanisms maintaining the AEJ in coupled models and highlights processes that should be improved in future ensembles.

Seeing the System from Above: The Use and Potential of Remote Sensing for Studying Ecosystem Dynamics
Authors: Senf Cornelius 
Published: September 2022

AbstractRemote sensing techniques are increasingly used for studying ecosystem dynamics, delivering spatially explicit information on the properties of Earth over large spatial and multi-decadal temporal extents. Yet, there is still a gap between the more technology-driven development of novel remote sensing techniques and their applications for studying ecosystem dynamics. Here, I review the existing literature to explore how addressing these gaps might enable recent methods to overcome longstanding challenges in ecological research. First, I trace the emergence of remote sensing as a major tool for understanding ecosystem dynamics. Second, I examine recent developments in the field of remote sensing that are of particular importance for studying ecosystem dynamics. Third, I consider opportunities and challenges for emerging open data and software policies and suggest that remote sensing is at its most powerful when it is theoretically motivated and rigorously ground-truthed. I close with an outlook on four exciting new research frontiers that will define remote sensing ecology in the upcoming decade.
Habitat thresholds for successful predation under landscape change
Authors: Atkinson Holly , Cristescu Bogdan , Marker Laurie , Rooney Nicola 
Published: September 2022

Abstract
Context
Habitat loss and alteration affect wildlife populations worldwide. Bush encroachment alters landscapes and threatens arid and semi-arid grasslands, but its effects on predator–prey relationships and carnivore community ecology are not well understood. Predation strategies of large predators, for example high-speed pursuits versus ambush from short distances, are likely to be affected differently by bush encroachment.

Objectives
We assessed how bush encroachment affects overall predation success of cheetahs (Acinonyx jubatus) and leopards (Panthera pardus) in a savanna landscape under variable fractional woody cover (FWC). We tested if predation success remained relatively unchanged for leopards across a gradient of FWC, and whether cheetah predation was most successful at low to intermediate cover and varied seasonally.

Methods
Belly scores of predators were measured from camera-trap images collected over 7 years in north-central Namibia and used to index predation success. We derived predicted belly score probabilities as a function of FWC, which was measured using a Synthetic Aperture Radar (SAR)-derived satellite data layer.

Results
Predicted leopard predation success was highest at 0.27–0.34 FWC in the dry season, potentially due to lower prey density in highly covered areas and decreased prey catchability in low cover. Predicted cheetah predation success was highest at 0.24–0.28 FWC in the wet season, potentially due to increased landscape openness, high availability of habitat margins for visualising and stalking prey, and decreased kleptoparasitism by leopards. These results highlight optimal habitat cover thresholds that favour lower FWC for cheetah than for leopard.

Conclusions
The findings indicate that landscape heterogeneity is important for predation success of cheetahs and leopards, suggesting that habitat management should focus on bush control efforts to maintain intermediate levels of bush cover.
Optimizing energy dissipation in gas foil bearings to eliminate bifurcations of limit cycles in unbalanced rotor systems
Authors: Papafragkos Panagiotis , Gavalas Ioannis , Raptopoulos Ioannis , Chasalevris Athanasios 
Published: September 2022

AbstractHigh-speed rotor systems mounted on gas foil bearings present bifurcations which change the quality of stability, and may compromise the operability of rotating systems, or increase noise level when amplitude of specific harmonics drastically increases. The paper identifies the dissipating work in the gas film to be the source of self-excited motions driving the rotor whirling close to bearing’s surface. The energy flow among the components of a rotor gas foil bearing system with unbalance is evaluated for various design sets of bump foil properties, rotor stiffness and unbalance magnitude. The paper presents a methodology to retain the dissipating work at positive values during the periodic limit cycle motions caused by unbalance. An optimization technique is embedded in the pseudo-arc length continuation of limit cycles, those evaluated (when exist) utilizing an orthogonal collocation method. The optimization scheme considers the bump foil stiffness and damping as the variables for which bifurcations do not appear in a certain speed range. It is found that secondary Hopf (Neimark–Sacker) bifurcations, which trigger large limit cycle motions, do not exist in the unbalanced rotors when bump foil properties follow the optimization pattern. Period-doubling (flip) bifurcations are possible to occur, without driving the rotor in high response amplitude. Different design sets of rotor stiffness and unbalance magnitude are investigated for the efficiency of the method to eliminate bifurcations. The quality of the optimization pattern allows optimization in real time, and gas foil bearing properties shift values during operation, eliminating bifurcations and allowing operation at higher speed margins. Compliant bump foil is found to enhance the stability of the system.
Truthmaker puzzles for one-level physicalists
Authors: Baysan Umut 
Published: September 2022

AbstractAccording to one-level physicalism, reality is exhausted by fundamental physical entities and properties. This position is sometimes defended on the basis of the truthmaker view of ontological commitment. Accordingly, physicalists can affirm higher-level truths without ontologically committing to any higher-level properties or states of affairs; fundamental physical states of affairs serve as truthmakers of all truths that have truthmakers, and a physicalist’s ontology should consist of nothing but the fundamental physical states of affairs and their constituents. In this paper, I raise a problem for one-level physicalists who defend their views by appealing to the truthmaker view of ontological commitment. I argue that the truthmaker view faces certain puzzles the solutions of which clash with the main tenets of one-level physicalism. I conclude that either truthmaking is not a good guide to ontological commitment or one-level physicalism cannot be defended on the basis of the truthmaker view.
Artifacting Identity. How Grillz, Ball Gags and Gas Masks Expand the Face
Authors: Voto Cristina , Soro Elsa 
Published: September 2022

AbstractBy questioning the attribution of a primary role to the eyes as bearers of identity within traditional Western culture, this paper will problematize the agentivity performed by the lower mereology of the face, identified with the mouth-nose assemblage. In particular, the study will focus on the manipulation of such facial spatiality through the intervention of three “lower face” artifacts: the grill, the ball gag and the gas mask. This piece of work will examine their plastic and figurative dimensions in the technological interaction with the facial organs. Furthermore, we will take into consideration the sociocultural context of wearability performed by the different bearers with the aim of grasping the identity shift that the artifacts trigger. The study, therefore, will organize the corpus as a sequence that starts inside the oral cavity where the grill is worn; then moves to a progressive exteriority with the ball gag that emerges from the mouth through the straps fastened around the head; eventually dealing with the exterior projection operated by the gas mask which by means of its filters portends beyond the anatomical face. Ultimately the three artifacts are presented as a threefold articulation of a liminal agency towards an expanded form of humanity including animality embedded within and without the space of meaning represented by the face.

Published: September 2022

AbstractTo examine the factors influencing the mental health and sociality of overseas Chinese left-behind children, and to identify the protective mechanisms of their mental health, the current study investigated 568 overseas Chinese left-behind children. The age distribution of the sample ranges from 10 to 16 years, with an average age of 13.51 years and a standard deviation of 1.11. Using the Adolescent Self-Rating Life Events Checklist, Perceived Social Support Scale, General Self-Efficacy Scale and Mental Health Inventory of Middle-school Students, results showed that: (1) Perceived social support played a moderate mediate role in the relationship between negative life events and mental health. (2) The effect of negative life events on perceived social support was moderated by general self-efficacy. Negative life events of overseas Chinese left-behind children with higher self-efficacy were more likely to experience negative mental health. Conclusion: Perceived social support plays a moderating mediating role in the relationship between negative life events and mental health of overseas Chinese left-behind children.

Published: September 2022

AbstractThe quality of the talent development environment and how it supports youth athletes has been identified as one major factor of success. Nonetheless, in psychological talent assessment there is a lack of standardized instruments addressing environmental aspects. One well-known questionnaire is the Talent Development Environment Questionnaire (TDEQ; Martindale et al., 2010). Until recently, the TDEQ had been translated into several languages, but not into German. Within this study, the five-factor, 25-item TDEQ‑5 (Li, Wang, Pyun, & Martindale, 2015) was systematically forward and backward translated and administered to 276 German youth athletes from different sports, aged between 13 and 21 years (mean [M] = 16.01; standard deviation [SD] = 2.1). In addition, 63 of these athletes completed both the German and English TDEQ‑5 to test for quality of translation. Confirmatory factor analysis revealed that the five-factor structure was acceptable according to the chi-square test to degrees of freedom ratio (1.9), root mean square error of approximation (0.058), and standardized root mean square (0.061). The comparative fit index (CFI) of 0.88 and the Tucker-Lewis Index of 0.86 was slightly below the 0.90 cut-off value. The reliabilities of the TDEQ‑5 factors were considered moderate to satisfactory (α = 0.62 to 0.75). In conclusion, the German TDEQ‑5 appears to be an applicable tool for use in research and applied settings but needs further analysis. In particular, we encourage future research to test the construct validity and ecological validity of the German TDEQ‑5 and suggest practitioners to utilize the tool to test and drive applied interventions within talent development environments.
