Learning in Temporary Teams: The Varying Effects of Partner Exposure by Team Member Role
Authors: Kim Song-Hee , Song Hummy , Valentine Melissa A. 
Published: March 2022

In many workplaces, temporary teams convene to coordinate complex work, despite team members having not worked together before. Most related research has found consistent performance benefits when members of temporary teams work together multiple times (team familiarity). Recent work in this area broke new conceptual ground by instead exploring the learning and performance benefits that team members gain by being exposed to many new partners (partner exposure). In contrast to that new work that examined partner exposure between team members who are peers, in this paper, we extend this research by developing and testing theory about the performance effects of partner exposure for team members whose roles are differentiated by authority and skill. We use visit-level data from a hospital emergency department and leverage the ad hoc assignment of attendings, nurses, and residents to teams and the round-robin assignment of patients to these teams as our identification strategy. We find a negative performance effect of both nurses’ and resident trainees’ partner exposure to more attendings and of attendings’ and nurses’ exposure to more residents. In contrast, both attendings and residents experience a positive impact on performance from working with more nurses. The respective effects of residents working with more attendings and with more nurses is attenuated on patient cases with more structured workflows. Our results suggest that interactions with team members in decision-executing roles, as opposed to decision-initiating roles, is an important but often unrecognized part of disciplinary training and team learning.

Tibial tuberosity-trochlear groove distance: does it measure up?
Authors: Krishnan Harry , Eldridge Jonathan D. , Clark Damian , Metcalfe Andrew J. , Stevens Jarrad M. , Mandalia Vipul 
Published: March 2022

Recognized anatomic variations that lead to patella instability include patella alta and trochlea dysplasia. Lateralization of the extensor mechanism relative to the trochlea is often considered to be a contributing factor; however, controversy remains as to the degree this contributes to instability and how this should be measured. As the tibial tuberosity-trochlear groove (TT-TG) is one of most common imaging measurements to assess lateralization of the extensor mechanism, it is important to understand its strengths and weaknesses. Care needs to be taken while interpreting the TT-TG value as it is affected by many factors. Medializing tibial tubercle osteotomy is sometimes used to correct the TT-TG, but may not truly address the underlying anatomical problem. This review set out to determine whether the TT-TG distance sufficiently summarizes the pathoanatomy, and if this assists with planning of surgery in patellar instability.

Implicit/Explicit, BEM/FEM Coupled Scheme for Acoustic Waves with the Wave Equation in the Second Order Formulation
Authors: Banjai Lehel 
Published: March 2022

Abstract
Acoustic scattering of waves by bounded inhomogeneities in an unbounded homogeneous domain is considered.
A symmetric coupled system of time-domain boundary integral equations and the second order formulation of the wave equation is described.
A fully discrete system consists of spatial discretization by boundary and finite element methods (BEM/FEM), leapfrog time-stepping in the interior, and convolution quadrature for the boundary integral equations.
Convolution quadrature is based on BDF2, trapezoidal rule, or a newly introduced truncated trapezoidal rule that has some favourable properties for both the implementation and quality of approximate solution.
We give a stability and convergence analysis under a CFL condition of the fully discrete system.
The theoretical results are illustrated by numerical experiments in two dimensions.

In this paper we continue our investigations of 4-dimensional complexes in [A. Cavicchioli, F. Hegenbarth, F. Spaggiari, Four-dimensional complexes with fundamental class, Mediterr. J. Math. 17 (2020), 175]. We study a class of finite oriented 4-complexes which we call

Inpainting of regular textures using ridge functions
Authors: Kazantsev Ivan G. , Turebekov Rauan Z. , Sultanov Murat A. 
Published: March 2022

Abstract
In this paper, we propose a
method for inpainting regular textures composed of oriented patterns
and completion of images distorted by
long stripes.
We have developed a model fit to describe a regular texture as a sum of a few ridge functions. The ridge functions are known in tomography as a result of a back-projection operator applied to projections, or samples of the Radon transform.
A computational scheme for the singular value decomposition of a regular texture into the sum of informative ridge functions is presented.
The numerical experiments on various images demonstrate the efficiency of the techniques proposed.
Serum spexin levels are not associated with size at birth but are associated with metabolic syndrome components in prepubertal children born at term
Authors: Öztürk Önsal Fatma Duygu , Elitok Gizem Kara , Bülbül Ali , Uçar Ahmet 
Published: March 2022

Abstract

Background
Babies born small for gestational age (SGA) are at risk of obesity and metabolic syndrome (MetS). Spexin (SPX) is a novel peptide implicated in food intake and obesity. Spexin levels are lower in obese subjects. This study investigated the potential association of SPX and some obesity related peptides such as leptin and active ghrelin with size at birth and MetS components in prepubertal children born term and either SGA or appropriate for GA (AGA). Secondary aim was to identify whether any of the investigated peptides were associated with MetS components.

Methods
We conducted a cross-sectional study of 37 consecutive (median age: 5.6 y) SGA- and 50 (median age: 5.9 y) AGA-born children. Clinical evaluations were performed using standard methods. Several biochemical variables (SPX, total leptin, and active ghrelin levels) were analyzed. Age-dependent cut-off values were used to define MetS components, including excess adiposity, hypertension, insulin resistance, and dyslipidemia. The associations between the assessed clinical and laboratory variables and MetS components were investigated.

Results
Children born SGA had higher frequencies of MetS components than AGA-born peers (p < 0.01). None of the investigated peptides were different between children born SGA and AGA after correcting for body mass index (p > 0.05 for all). Serum SPX levels were lower in children with at least one metS component than those without MetS components (p = 0.018).

Conclusions
Size at birth had no association with serum SPX. Serum SPX levels are decreased in prepubertal children with MetS components.

Published: March 2022

Abstract
The relevance of this study is conditioned by the high degree of importance of creating the latest modifications of the polymer–bitumen binder for the manufacture of high-quality asphalt concrete, for its subsequent use in the construction of motorways and concrete pavements of airfields. In this context, the purpose of the study is to obtain new, scientifically substantiated technological solutions for the development and practical application of effective nanomodified polymer-bitumen binders (PBBs) that can improve the operational characteristics and duration of practical use of asphalt. The study results clearly demonstrate the fact that carbon nanotubes (CNTs) are a stabiliser and an ageing inhibitor of polymer–bitumen binders (PBBs), while contributing to a decrease in the intensity of its operational destruction over time by more than 10 times relative to the compositions of PBB with structuring additives, which is essential in the preparation and practical use of asphalt concrete for the construction of motorways and airfields. The results obtained are of significant importance for developers of modern technologies for manufacturing asphalt concrete for road construction, and road maintenance workers who professionally solve the problems of road maintenance, applying the latest practical developments in the field of road construction and repair in their activities.
Research trends in the development of anodes for electrochemical oxidation of wastewater
Authors: Rai Devendra , Sinha Shishir 
Published: March 2022

Abstract
The review focuses on the recent development in anode materials and their synthesis approach, focusing on their compatibility for treating actual industrial wastewater, improving selectivity, electrocatalytic activity, stability at higher concentration, and thereby reducing the mineralization cost for organic pollutant degradation. The advancement in sol–gel technique, including the Pechini method, is discussed in the first section. A separate discussion related to the selection of the electrodeposition method and its deciding parameters is also included. Furthermore, the effect of using advanced heating approaches, including microwave and laser deposition synthesis, is also discussed. Next, a separate discussion is provided on using different types of anode materials and their effect on active •OH radical generation, activity, and electrode stability in direct and indirect oxidation and future aspects. The effect of using different synthesis approaches, additives, and doping is discussed separately for each anode. Graphene, carbon nanotubes (CNTs), and metal doping enhance the number of active sites, electrochemical activity, and mineralization current efficiency (MCE) of the anode. While, microwave or laser heating approaches were proved to be an effective, cheaper, and fast alternative to conventional heating. The electrodeposition and nonaqueous solvent synthesis were convenient and environment-friendly techniques for conductive metallic and polymeric film deposition.
Urban-economic geographies beyond production: Nairobi’s sociotechnical system and the challenge of generative urbanization
Authors: Murphy James T. 
Published: March 2022

AbstractUrban-regional economies are developing in highly variegated, uneven ways globally. In economic geography, studies of urban-regional development emphasize the prospects for innovative, globally-competitive industrial sectors to emerge and enhance a city-region’s exchange value in global markets. This focus reflects a productivist bias that may fail to address issues related to the use-value of, or living conditions associated with urban transitions. Such concerns are particularly significant in the Global South where urbanization has often not led to socioeconomic transformations that benefit the majority of urban residents. To examine the relationships between a city’s exchange and use value, this paper argues for a sociotechnical systems approach that conceptualizes cities as constituted by interdependent or coupled regimes related to production, consumption, and infrastructure that stabilize urban-regional economies and determine development pathways. The framework is deployed empirically to examine the case of Nairobi, Kenya – a rapidly growing urban-regional economy characterized by high rates of inward foreign direct investment, principally in speculative real estate ventures in the consumption regime. Domestic manufacturing industries (the production regime) are stagnating, struggling to compete against imports, and failing to generate widespread formal employment and raise tax revenues for the infrastructure regime. The net result is a city characterized by fragmented or splintered regimes that create highly uneven, exclusionary development outcomes. These dynamics and findings are analyzed in relation to a similar study of Dar es Salaam, Tanzania in order to demonstrate the comparative potential of this conceptual approach. The paper concludes with a call for economic geographers to better account for the use-value of urban-regional economies such that development concerns beyond production become more central to our analyses.

Published: March 2022

Abstract
Gruppierungs- und Reihenfolgeprobleme der Fertigung zählen zu den zentralen Fragestellungen der operativen Produktionsplanung. Gruppierung bezeichnet dabei die zu treffenden Entscheidungen über Größe und zeitliche Lage von Fertigungsaufträgen (Losen), während der Reihenfolgeaspekt die Belegung der Anlagen zum Gegenstand hat. Im vorliegenden Beitrag wird ein neues konzeptionelles Modell vorgestellt, mit dessen Hilfe Gruppierungs- und Reihenfolgeentscheidungen bei reihenfolgeabhängigen Rüstvorgängen simultan getroffen werden können. Schließlich wird diskutiert, wie sich das vorgeschlagene Gruppierungs- und Reihenfolgemodell verallgemeinern läßt.

Wissensbasiertes Datenmodell für Konstruktion und Arbeitsplanung
Authors: Tönshoff Hans Kurt , Zahn Guido 
Published: March 2022

Abstract
Obwohl in der Konstruktion oftmals moderne CAD-Systeme eingesetzt werden, ist die digitale Übernahme geometrischer oder gar technologischer Daten aus der Konstruktion in der Praxis kaum zu finden. Eine kürzlich durchgeführte Umfrage zeigt deutlich, daß sich darüber hinaus häufig erhebliche Probleme durch nicht fertigungsgerecht gestaltete Werkstücke ergeben. Es wurde daher ein auf Technischen Elementen basierendes Datenmodell entwickelt, das die Abbildung und den Austausch aller im Bereich von Konstruktion und Arbeitsplanung relevanten Daten zuläßt sowie das zur Planung und Fertigung eines beschriebenen Werkstücks notwendige fertigungstechnische Wissen enthält.

Abstract
Lewis, MH, Siedler, MR, Lamadrid, P, Ford, S, Smith, T, SanFilippo, G, Waddell, B, Trexler, ET, Buckner, S, and Campbell, BI. Sex differences may exist for performance fatigue but not recovery after single-joint upper-body and lower-body resistance exercise. J Strength Cond Res 36(6): 1498–1505, 2022—This study evaluated sex differences in performance recovery and fatigue during dynamic exercise. Twenty-eight resistance-trained males (n = 16) and females (n = 12) completed a repeated-measures, randomized, parallel-groups design. The protocol consisted of a baseline assessment, a recovery period (4, 24, or 48 hours), and a postrecovery assessment. The assessments were identical consisting of 4 sets of 10 repetition maximum (10RM) bicep curls and 4 sets of 10RM leg extensions to failure. Recovery was quantified as the number of total repetitions completed in the postrecovery bout. Fatigue was quantified as the number of repetitions completed set to set within the session. For analysis, we set the level of significance at p ≤ 0.05. No sex differences in performance recovery were observed across any of the investigated time periods for either exercise modality. Regarding fatigue, significant effects were observed for set (p < 0.001) and sex (p = 0.031) for bicep curls. Repetitions dropped in later sets, and females generally completed a greater number of repetitions than males (8.8 ± 0.5 vs. 7.2 ± 0.5). For leg extension, a significant sex × set interaction was observed (p = 0.003), but post hoc tests revealed these sex differences as marginal. Our results suggest that in dynamic bicep curls and leg extensions, other factors unrelated to sex may be more impactful on performance recovery. To optimize an athlete's desired adaptations, it may be more important to consider other variables unrelated to sex such as volume, perceived exertion, and training history when formulating training prescriptions for single-joint exercises.

Abstract
Cross, JA, Higgins, AW, Dziuk, CC, Harris, GF, and Raasch, WG. Relationships among shoulder rotational strength, range of motion, pitching kinetics, and pitch velocity in collegiate baseball pitchers. J Strength Cond Res XX(X): 000–000, 2022—Throwing shoulder injuries are the most common type of injury experienced by baseball pitchers. Weakness in the shoulder musculature and insufficient throwing arm range of motion are both risk factors for developing a shoulder injury. The goal of this study was to determine correlations among shoulder rotational strength, range of motion, pitching kinetics, and pitch velocity in collegiate pitchers. Thirteen uninjured male college pitchers were evaluated. Clinical measures included shoulder internal and external rotation range of motion, peak isokinetic internal and external rotator strength, and peak isometric internal and external rotator strength. Three-dimensional biomechanics were assessed as subjects threw from an indoor pitching mound to a strike zone net at regulation distance. Pearson's correlations were used to assess the associations among the clinical measures and throwing metrics. Five significant correlations were found between peak shoulder compressive force and strength, and 4 significant correlations were found between pitching velocity and strength (p < 0.05). No significant correlations were found between range of motion and pitching kinetics or velocity. Our results suggest that as shoulder rotational strength increases, the peak shoulder compressive force and pitch velocity both increase. Knowledge of relationships between strength metrics and pitching biomechanics may allow for improved strength training routines with the goal of increasing velocity without increasing injury risk.

Abstract
Riboli, A, Esposito, F, and Coratella, G. Small-sided games in elite football: practical solutions to replicate the 4-min match-derived maximal intensities. J Strength Cond Res 37(2): 366–374, 2023—The purpose of the study was to determine the area per player (ApP, m2·player−1) to replicate the maximal 4-min match-play period (4-minPeak) using small-sided or large-sided games (SSGs) lasting the same duration in elite football players. Twenty players (age: 26 ± 5 years) competing in European championship and international UEFA competitions were monitored during SSGs with (SSGwith) or without (SSGwithout) goalkeepers, both lasting 4-min. A total of 1,724 and 561 individual observations for SSGwith and SSGwithout across 99 and 34 different SSGs formats were undertaken. Whole (90-minavg) and 4-minPeak match demands were calculated. Relative (m·min−1) total, high-speed (HSRD), very high-speed (VHSRD), sprint, and acceleration/deceleration distance were collected. For both SSGwith and SSGwithout, ApP was small-to-very-largely correlated with TD, HSRD, VHSRD, and sprint, whereas an inverse trivial-to-small correlation with acceleration/deceleration was found. In SSGwith, the ApP to replicate 4-minPeak was larger (p < 0.001, effect size [ES]: 0.33–5.80) than that to mimic 90-minavg for total distance, HSRD, VHSRD, and sprint, whereas for acceleration/deceleration the ApP was lower (p < 0.001, ES: −3.13 to 0.48) for 4-minPeak. In SSGwithout, the ApP to replicate 4-minPeak was larger (p < 0.001, ES: 0.04–3.72) than that to mimic 90-minavg for HSRD, VHSRD, and sprint. Some positional differences (p < 0.05, ES: 0.22–1.10) in ApP were found. The ApP to replicate 4-minPeak was higher for SSGwith than SSGwithout (p < 0.001, ES: 0.67–3.58). These findings may help practitioners to recreate the 4-minPeak to manage ApP during SSGs in elite football.
