Background

Malnutrition is common among children with cerebral palsy (CWCP); however, its impact on gross motor function (GMF) is not adequately reported. The study evaluated the influence of malnutrition and body composition on GMF.

Methods

In the cross-sectional survey, CWCP were recruited using purposive sampling from three selected secondary and tertiary hospitals in Kano, Nigeria. Sociodemographic variables were recorded on a data capture form. Anthropometric variables were measured using standard procedures. Percent (%) body fat, malnutrition, and GMF were assessed using skinfold thickness, screening tool for the assessment of malnutrition in pediatrics, and GMF classification system (GMFCS), respectively. The data was analyzed with one-way ANOVA, chi-square, and logistic regression using SPSS version 20 at p < 0.05.

Results

The 146 CWCP have mean age of 4.70 ± 2.46 years. About 95 (65.1%) are malnourished. Those with GMFCS V had lower %body fat and higher malnutrition than children with GMFCS II and I, respectively (p < 0.05). Malnutrition has no significant influence on GMF (B = 0.984, OR = 2.676; 95% CI = 0.965–7.423, p > 0.05). %body fat (B = −0.192, OR = 0.826; 95% CI = 0.687–0.992, p < 0.05), type of CP (OR = 12.106; 95% CI = 3.771–38.866, p < 0.005), child’s position in the family (OR = 1.639; 95% CI = 1.162–2.312, p < 0.05), and mothers’ education (B = −2.815, OR = 0.060; 95% CI = 0.012–0.309, p < 0.005) all predicted GMF.

Conclusions

Majority of the CWCP in this study are malnourished. But malnutrition did not however significantly predict GMF, meaning that though malnutrition could impair children’s physical growth and motor development, it however did not have significant influence on their motor function. Hence, CWCP undergoing rehabilitation may not likely experience significant decrease in their motor function due to inadequate nutrition. Decrease in body fat, type of CP, low level of mothers’ education, and child occupying 4th or more position in the family have negative influence on GMF. It was recommended that physiotherapists should routinely assess for malnutrition in CWCP. Prompt nutritional intervention may prevent considerable lose of body fat and augment the gains of physical rehabilitation by providing appropriate nutrition to support muscle growth and the supply of adequate energy for participation in physical exercise. Adequate caregiver education is important for ensuring satisfactory nutrition for CWCP.

Bioclimatic variables are indicators reflecting the integrated relationship between living things and climate. They are often used to interprete the relationships between species, vegetations and climate in global change research, and further simulate the geographical distribution patterns of both species and vegetations, as well as their functional characteristics. Regional bioclimate datasets, however, have been rarely reported. Based on an ANUSPIN interpolated dataset (covering temperature, precipitation and sunshine percentage) of 1km-resolution climate variables in China at 30-year basis averaged from 1951 to 1980 and from 1981 to 2010, respectively, we calculated 9 kinds bioclimatic variables in this study, namely mean temperature of the coldest month, mean temperature of the warmest month, absolute maximum temperature, absolute minimum temperature, annual growing degree days above 0°C and 5°C, growing season precipitation, annual drought index and annual moisture index. We plotted their spatial distribution map and analyzed their spatial pattern and trend statistically. Comparative analysis shows that the variation range of corresponding variables is very narrow, and the statistical variables are nearly the same. Therefore, the error of this dataset mainly comes from the spatial distribution dataset of basic climatic factors, and the secondary error in the process is tiny.This dataset provides reasonable environmentally mechanistic explanations for research on the relationships between species, vegetations and climate, and offers a convenient and diverse way for researchers to use bioclimatic variables to simulate species distribution patterns, vegetation structures and functions.

Spatialized population data are of great importance for supporting the studies on transportation, geography, socio-economy, sustainable development etc. In this paper, we collected the district/county-level population data of China’s six population censuses starting from 1949. With the administrative division in 2015 (the year of the Sixth Population Census) as the benchmark of the geographical region of the districts and counties, we calibrated and spatialized the population data to obtain a dataset of district/county-level population distribution of China’s six national censuses.
Reputation evaluation and its impact on the human cooperation—A recent survey
Authors: Wang Juan , Xia Chengyi
Published: January 2023

In this survey, we briefly review some recent advances in the field of indirect reciprocity and reputation mechanism along the routes of theoretical modeling and behavior experiments. Firstly, various game models with reputation evaluation are proposed, and large quantities of numerical simulations demonstrate that introducing the reputation evaluation drastically enhances the level of collective cooperation within the population. In particular, the so-called leading eight rules are found to be evolutionarily stable strategies. Secondly, through extensive human experiments played in the laboratory or via the online labor market, it is validated that providing enough information on the individual strategy or reputation status will help players to select the cooperative partners or perform the rational decision, which eventually facilitates the evolution of cooperation, but some experiments also indicate that allowing the link rewiring may dominate the human cooperation. Finally, several potential and valuable directions are pointed out so as to further explore how the cooperation evolves within the real-world population.

Energetics of a self-gravitating quantum system of charged particles
Authors: Lotte Baljeet Kaur , Mishra Subodha , Mahapatra Prasanta Kumar
Published: January 2023

Extending our model of Newtonian Quantum Gravity (NQG) in a self-gravitating system (Lotte B. K. and Mishra S., Mod. Phys. Lett. A, 35 (2020) 2050081), we study here the energetics of a charged self-gravitating quantum many-particle system. The model is based on the use of the uncertainty principle and the incorporation of necessary relativistic corrections. From the resulting ground state energy we have derived the effective radius of the system of charged particles, after it gets collapsed under its own gravity. Additional results like the Hawking temperature and the Buchdahl-Andréasson (BA) limit for this system are also explored. We further show a possible link of this collapsed system of self-gravitating charge particles, with the notion of a charged black hole.

Published: January 2023

The management of patients on direct oral anticoagulants (DOACs) who require emergent cardiac surgery is slowly evolving. The introduction of andexanet alfa, a novel antidote for apixaban and rivaroxaban, added a specific reversal agent to our armamentarium, but its safety and efficacy are still being investigated. We report 2 patients on DOAC treatment who required emergency cardiac surgery. Both received perioperative andexanet alfa together with prothrombin complex concentrate (PCC) at some time during 6 hours before operative management. Heparin resistance was noted in each instance, and pump thrombosis developed in 1 case.
The Landmark Series: Intraductal Papillary Mucinous Neoplasms of the Pancreas—From Prevalence to Early Cancer Detection
Authors: Pollini Tommaso , Wong Paul , Maker Ajay V.
Published: January 2023

Modern series report a prevalence of pancreatic cysts in the general population of up to 50% in prospective studies. Of these, about half will be pancreatic cystic neoplasms (PCNs) that have varying degrees of malignant potential. Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are the most common PCNs and are known predecessors of pancreatic adenocarcinoma. Critically, they are one of the only radiographically identifiable precursors of pancreatic cancer and thus provide an opportunity for early cancer detection and surgical resection with curative intent. The combination of high prevalence and potential for malignant degeneration underscore the relevance of discussing the best management of IPMNs and improving the existing standard of care. Landmark data on IPMN prevalence, guidelines, surveillance, biomarkers, and immune landscape are highlighted.

Published: January 2023

This paper analyzes the works of management classics such as Russell Ackoff, Nancy Adler, Frederick Herzberg, Chris Argyris, Bennis Warren, Lyndall Urwick, experts of Aston Group, and others. A common bond between them is organizational behavior and the fact that their work was written in the last century and that elements of their theories were the basis for the neoclassical management theories that predominate today.

Purpose. The aim is to identify commonalities with the iterative-incremental (agile) approach to development and management from classical management theories.

Methodology. The paper analyses classical management papers in organizational behavior and leadership theory to identify commonalities with the iterative-incremental approach to management. The two categories are considered holistically, as leadership can determine organizational behavior. The paper applies ontological and integrated approaches.

Results. The paper identifies standard features of classical theories and agile approaches to management. It indicates that classical approaches to management have formed the basis of agile approaches to management.

Practical implications. The results apply to social management and organizational psychology scholars. In addition, the results will help to scientists write textbooks and manuals on management theory and related disciplines. The study’s results contribute to developing the history of managerial thought.

Published: January 2023

Purpose – offer different variants of building multiple regression models to describe real economic processes.

Method or methodology of the work: the article uses the econometric method of data analysis.

Results: it was shown that econometric methods are effective in describing the hidden dependencies of the economic system. The study proposes several ways to build regression models: the classical version using the matrix of pairwise correlation coefficients (correlation pleiades method), the method of inflation factors, denying the presence of “moderately strong” dependence, after which the removal of “unnecessary” factors was performed using Gretl tool “Test for excess variables”, as well as using the principal components method to consider the influence of all factors on the dependent variable. In order to facilitate the interpretation of the results obtained, the article shows the transition from the principal components to the original data. The model is built on a publicly available dataset available to the research community.

The sphere of application of the results: in practice, the results are useful for planning effective strategies for the development of individual states, as well as a manual for beginner econometricians wishing to learn different approaches to econometric modeling with the use of effective tools.

El problema ontológico en la era digital.
Authors: Morales Carrillo José Tadeo
Published: January 2023

El planteamiento que a continuación se detalla es la disposición, desde la crítica filosófica, para el establecimiento del debate ontológico en la era digital atendiendo a la situación humana inmersa en una nueva realidad donde emergen, de manera recursiva, las preguntas originarias sobre el ser y su temporalidad. La discusión se fundamenta en la expansión y uso del término ontología frente a la respuesta de Heidegger del “lenguaje como casa del ser” y el cuestionar al quién genera la pregunta, haciendo de ello el centro de la ontología donde lo digital se presenta como un estar a la mano para aligerar la cuestión sobre el ser y la realidad humana afectada por la pandemia COVID-19 como situación límite
El tiempo vencido por el amor (Pervivencia, supervivencia y anástasis en Jean-Luc Nancy)
Authors: Cereceda Sánchez Miguel
Published: January 2023

Partiendo de una alegoría barroca, en la que se representa al tiempo vencido por la esperanza, la fama y el amor, el artista madrileño Jaime Aledo (nacido en Cartagena, Murcia, en 1949) emprende una larga reflexión irónico-pictórica sobre las posibilidades de la obra de arte de perpetuar la gloria y la memoria del artista, más allá de la muerte. Dicha reflexión es aprovechada como pretexto para introducir una meditación sobre la idea del filósofo francés Jean-Luc Nancy de recuperar la doctrina cristiana de la anástasis, como idea de la supervivencia, en el contexto de su proyecto de “reconstrucción del cristianismo
El arte de la fotografía durante la crisis del SIDA
Authors: Parra Montero Francisco
Published: January 2023

Si algo caracterizó el mundo del arte, durante los últimos años del siglo XX, fue la crisis provocada por el SIDA transformando su escenario. El campo de la fotografía aportó un amplio abanico de imágenes capaces de conmocionar, e incluso de alterar conductas, canalizando el sufrimiento del enfermo desde un lugar privilegiado. El retrato fotográfico se reiteró en el terreno artístico y los trabajos realizados se convirtieron en auténticos documentos sociales de una época. La necesidad de ponerle rostro al virus, y de luchar contra el estigma, propició el desarrollo de una temática fotográfica que agitó conciencias. Los profesionales, lejos del sensacionalismo, captaron la pandemia de múltiples maneras desde una óptica realista, poética en algunos casos, pero siempre con un protagonista absoluto como era el desahuciado, el cual se dejó fotografiar sin ningún tabú.

El alcance de la obligación preventiva durante el desplazamiento trasnacional de trabajadores: riesgos específicos y accidente en misión.
Authors: García Gallego Carlos
Published: January 2023

Los trabajadores desplazados en el marco de una prestación de servicios transnacional afrontan riesgos específicos que han de ser tenidos en cuenta para dotar de protección a los trabajadores afectados. Aunque no se trate de riesgos directamente vinculados con el trabajo a realizar por el trabajador desplazado, son riesgos relacionados con las circunstancias y el entorno del país de destino, donde el trabajador se enfrenta a un nuevo contexto, en unas condiciones sanitarias, de seguridad vial, sociales y meteorológicas distintas a las que tenía en el país de origen. A estas condiciones habría que sumar los riesgos de carácter psicosocial debidos en buena medida a las diferencias de cultura preventiva entre los países de origen y destino y la barrera cultural y lingüística. Además, el tiempo en el que el trabajador se encuentra desplazado en los términos del artículo 2.1 de la Ley 45/1999 debe considerarse un envío en misión en términos preventivos. En consecuencia, en caso de accidente se amplía la presunción de que se trata de tiempo y lugar de trabajo, sin que el accidente tenga que reunir los requisitos del accidente in itinere. La relevancia de considerar un accidente como accidente en misión, no se agota con la determinación de la contingencia como profesional, y por tanto de la correspondiente prestación a cargo del sistema de Seguridad Social; pues a partir de dicho concepto se determina el propio contenido de la obligación preventiva de la empresa, que desplaza trabajadores a otro país para la prestación de un determinado servicio.
La subcontratación como factor de riesgo específico en el desplazamiento trasnacional de trabajadores.
Authors: García Gallego Carlos
Published: January 2023

Existe una probada vinculación entre el incremento de la siniestralidad y el exceso en las cadenas de subcontratación. Una forma de organización de la producción que, en el ámbito internacional, ha originado nuevos factores de riesgo. De ahí que la regulación que limita la subcontratación, como factor de riesgo específico, constituya una medida muy eficaz de prevención de riesgos laborales; existiendo medidas de control ajustadas a las particularidades del sector de la construcción. Igualmente, la consideración de los trabajadores desplazados que prestan servicios trasnacionales, como los trabajadores especialmente sensibles a los riesgos derivados del trabajo, merece una atención especial a la hora de garantizar a estos trabajadores el derecho a una protección eficaz en materia de seguridad y salud en el trabajo.
El teletrabajo y el desplazamiento de trabajadores a través de plataformas digitales.
Authors: Tatay Puchades Carmen
Published: January 2023

La digitalización de la economía, especialmente en el contexto de la pandemia provocada por la crisis del COVID-19, abre un nuevo escenario de análisis sobre distintas alternativas para regular el teletrabajo. Se requiere, pues, un nuevo enfoque y una evaluación completa y profunda de los problemas de interpretación y aplicación respecto del lugar de prestación de servicios de los teletrabajadores internacionales, a fin de determinar las condiciones de trabajo aplicables y la legislación aplicable en materia de Seguridad Social. Por otra parte, en la actualidad son muchas las empresas que ofrecen los servicios de trabajadores desplazados a través de plataformas digitales. En mayor o menor medida, las plataformas pueden establecer los términos en los que los “trabajadores desplazados proveedores de servicios” suministran su trabajo y, por lo tanto, la relación entre los proveedores de servicios y las plataformas puede exhibir algunas de las características asociadas con las relaciones laborales, lo que podría resultar en un falso trabajo por cuenta propia. Esto presenta un desafío sustancial para el derecho laboral.
DISCURSIVE CONSTRUCTIONS OF WASTE AND SLOW VIOLENCE IN ANN PANCAKE’S STRANGE AS THIS WEATHER HAS BEEN.
Authors: Villamarín Freire Sara
Published: January 2023

This paper addresses the representation of environmental destruction in the Appalachian coalfields in the novel Strange as this Weather Has Been (Ann Pancake, 2007). Pancake’s book follows the disbandment of a family of six in southern West Virginia and presents us with the dilemmas they must confront, most notably whether they should leave or stay and organize against the coal company. I seek to analyze the ways in which the novel conveys each character’s embodied, material experience when facing environmental destruction; moreover, I examine the way in which slow violence is represented in the text. Focusing on Appalachia’s extractivist past (and present), I argue that Strange as this Weather Has Been ultimately helps to counter the existing prejudice against poor whites in the region by fostering reader empathy through the textual recreation of the bleak environmental condition in the novel’s storyworld.
POETRY IN PANDEMIC TIMES: MOURNING COLLECTIVE VULNERABILITY IN SUE GOYETTE’S SOLSTICE 2020. AN ARCHIVE.
Authors: Martínez Serrano Leonor María
Published: January 2023

Focusing on Canadian poet Sue Goyette’s collection Solstice 2020. An Archive (2021), this article examines how dealing with the effects of a global pandemic through the medium of poetry can act as a powerful catalyst in raising awareness about collective vulnerability and mourning. During the locked-down days of 2020, Goyette felt it was her responsibility as a poet to find words to convey the sense of shared vulnerability people experienced in the face of a momentous event that confined them to their homes for days on end. Drawing on vulnerability theory, ecophilosopher David Abram’s thinking on the more-than-human world, Stacy Alaimo’s concept of trans - corporeality, as well as on recent theorizations on the COVID-19 pandemic, this article argues that Goyette’s Solstice 2020 is a most interesting sociological document that represents collective vulnerability, testifies to the conundrums posed by the still ongoing pandemic, and makes visible the deep affinities between humankind and the more-than-human world.

Seringal de Miguel Ferrante: exploração do homem nos seringais da Amazônia
Authors: Nenevé Miguel , Costa Giselle
Published: January 2023

Neste artigo exploramos a questão de violência e opressão do trabalhador da borracha nos seringais da Amazônia, visível no romance Seringal, do escritor Miguel Ferrante. O romance é ambientado no seringal Santa Rita, no interior da Amazônia acreana, na primeira metade do século XX. A narrativa reproduz a vida opressiva de seringueiros que trabalham para o dono do seringal, o “coronel” bem como revela o tratamento que se dá às mulheres, “objeto de desejos” de seringalista e seringueiros. Visando sempre o lucro, o dono do seringal explora e escraviza o trabalhador da seringa, tomando atitudes de violência contra seu próprio trabalhador. O romance também revela a condição sub-humana em que vive a mulher no seringal que é ainda mais colonizada e explorada que o homem seringueiro. O seringalista, todo poderoso, sente-se no direito de explorar e estuprar as mulheres indefesas. Argumentamos que o romance de Ferrante continua atual, uma vez que a violência contra a mulher e contra os trabalhadores nos dias de hoje ainda são perceptíveis. Apoiamos o trabalho em teóricos como o pensador decolonial Anibal Quijano (2005), Frantz Fanon (1979) que escreveu sobre a relação da violência com a colonização, Samuel Benchimol (1992), pesquisador da História da exploração da borracha na Amazônia e Cristina Wolf (2001) pesquisadora brasileira que investigou casos de violência nos seringais do estado do Acre.

Imagem da sociedade brasileira no jornal Lud do período entre 1930–1938
Authors: Caban Anna
Published: January 2023

Em 1920, no ano do seu encerramento, o jornal Polak w Brazylii ficou na posse da Congregação dos Vicentinos de Curitiba. No mesmo ano, o periódico ressurgiu com um nome novo – Lud, mudando radicalmente o perfil para eclesiástico- -conservador, com o primeiro redator Pe. José Joaquim Góral (Malczewski, 2008: 217). No período entre 1930 a 1938, o jornal fornece as informações pertinentes tanto à sua mãe-pátria, para estimular o sentimento de pertença à mesma etnia, como ao Brasil, incentivando a integração na sociedade de acolhimento. O contexto da referida época, da crise económica global até à campanha de nacionalização de Getúlio Vargas, afeta, sem dúvida, o discurso veiculado nas publicações dos missionários, não só a sua visão do Outro, mas também a imagem da sua etnia. Assim sendo, o objetivo do nosso trabalho é apresentar e analisar a heteroimagem da sociedade brasileira, caracterizada pela diversidade étnica, conforme o periódico Lud, numa época marcante entre 1930 a 1938, tendo em consideração a influência da autoimagem dos poloneses.

Camões e a globalização da Língua Portuguesa
Authors: Ferro Manuel
Published: January 2023

Partindo do poema “Inês de Leiria” de Afonso Lopes Vieira, por sua vez inspirado no capítulo 19 da Peregrinação de Fernão Mendes Pinto, ali se relata uma das aventuras deste autor no interior da China em pleno século XVI: o encontro com uma chinesa que reza “Padre Nosso que estais nos céus…”, a única coisa que sabe do Português, mas que é o suficiente para surpreender o viajante e lhe permite um inesperado contacto com a língua materna. É verdade que na época se tinha superado a fase de evolução da língua a partir do latim vulgar, passando pela fase inicial de formação do romance e, depois, do galaico-português, com a consequente separação do Galego e do Português. O século XVI foi uma época de oiro, de sistematização, enriquecimento e exaltação da Língua Portuguesa, mediante os contributos da generalidade dos escritores e, muito em particular, de António Ferreira e Luís de Camões, de modo a criar-se uma norma linguística. O idioleto de Camões tornou-se de tal modo modelar que foi reconhecido nos séculos seguintes pelos gramáticos, teorizadores e críticos como padrão, ao mesmo tempo que o Poeta se arvorava em símbolo máximo da identidade nacional. Em paralelo, graças às viagens e contactos com outras terras, povos e culturas, lançam-se as bases do Português como língua de contacto a nível global, antecipando- se na modernidade a consciência nacional duma comunidade de países de expressão portuguesa, e surgindo do intercâmbio com os povos nativos os crioulos e pidgins, além da presença inesperada da nossa língua em horizontes geográficos e linguísticos variados, pelo que se constituiu em simultâneo e em Português o maior banco de dados da primeira grande experiência de globalização do mundo conhecido.
An Adaptive Lagrangian-Based Scheme for Nonconvex Composite Optimization
Authors: Hallak Nadav , Teboulle Marc
Published: January 2023

This paper develops a novel adaptive, augmented, Lagrangian-based method to address the comprehensive class of nonsmooth, nonconvex models with a nonlinear, functional composite structure in the objective. The proposed method uses an adaptive mechanism for the update of the feasibility penalizing elements, essentially turning our multiplier type method into a simple alternating minimization procedure based on the augmented Lagrangian function from some iteration onward. This allows us to avoid the restrictive and, until now, mandatory surjectivity-type assumptions on the model. We establish the iteration complexity of the proposed scheme to reach an ε-critical point. Moreover, we prove that the limit point of every bounded sequence generated by a procedure that employs the method with strictly decreasing levels of precision is a critical point of the problem. Our approach provides novel results even in the simpler composite linear model, in which the surjectivity of the linear operator is a baseline assumption.

Monotone Inclusions, Acceleration, and Closed-Loop Control
Authors: Lin Tianyi , Jordan Michael I.
Published: January 2023

We propose and analyze a new dynamical system with a closed-loop control law in a Hilbert space [Formula: see text], aiming to shed light on the acceleration phenomenon for monotone inclusion problems, which unifies a broad class of optimization, saddle point, and variational inequality (VI) problems under a single framework. Given an operator [Formula: see text] that is maximal monotone, we propose a closed-loop control system that is governed by the operator [Formula: see text], where a feedback law [Formula: see text] is tuned by the resolution of the algebraic equation [Formula: see text] for some [Formula: see text]. Our first contribution is to prove the existence and uniqueness of a global solution via the Cauchy–Lipschitz theorem. We present a simple Lyapunov function for establishing the weak convergence of trajectories via the Opial lemma and strong convergence results under additional conditions. We then prove a global ergodic convergence rate of [Formula: see text] in terms of a gap function and a global pointwise convergence rate of [Formula: see text] in terms of a residue function. Local linear convergence is established in terms of a distance function under an error bound condition. Further, we provide an algorithmic framework based on the implicit discretization of our system in a Euclidean setting, generalizing the large-step hybrid proximal extragradient framework. Even though the discrete-time analysis is a simplification and generalization of existing analyses for a bounded domain, it is largely motivated by the aforementioned continuous-time analysis, illustrating the fundamental role that the closed-loop control plays in acceleration in monotone inclusion. A highlight of our analysis is a new result concerning [Formula: see text]-order tensor algorithms for monotone inclusion problems, complementing the recent analysis for saddle point and VI problems.

Precommitments in Two-Sided Market Competition
Authors: Hu Ming , Liu Yan
Published: January 2023

Problem definition: We consider a two-sided market competition problem where two platforms, such as Uber and Lyft, compete on both supply and demand sides and study the impact of precommitments in a variety of practically motivated instruments on the equilibrium outcomes. Academic/practical relevance: We extend a set of classic oligopoly pricing results to account for two-sided competition under demand uncertainty. Methodology: We investigate multi-stage competition games. Results: We start with a sufficiently low demand uncertainty. First, we show that a precommitment made on the less competitive (demand or supply) side (on price or wage) has a less intense outcome than no commitment (i.e., spot-market price and wage competition). Then we show that, somewhat surprisingly, if the competition intensities of both sides are sufficiently close, the commission precommitment, where the platforms first compete in setting their commission rates and then their prices, is less profitable than no precommitment at all, and vice versa. Furthermore, we show that the capacity precommitment, in which the platforms first commit to a matching capacity and then set price and wage simultaneously subject to the precommitted capacity, leads to the most profitable outcome of all competition modes and extends the celebrated Kreps-Scheinkman equivalency to the two-sided market (without demand uncertainty). Then we extend the comparisons of various competition modes to account for a relatively high demand uncertainty. We show that the comparison between the spot-market price and wage competition and the commission precommitment stays the same as that with a sufficiently low demand uncertainty. In addition, the more flexible competition modes, such as no commitment and commission precommitment, benefit from higher demand uncertainty (with a fixed mean demand) because of their operational flexibility in response to the market changes. Further, a relatively high demand uncertainty may undermine or enhance the value of the wage precommitment, as opposed to no commitment. Finally, we also account for platforms with asymmetric parameters and matching friction and find that our main insights tend to be robust. Managerial implications: Our results caution platforms that a precommitment to the wrong instrument can be worse than no commitment at all. Moreover, the regulation of classifying gig workers as employees, despite many of its benefits to workers, may lead to a less competitive market outcome and, surprisingly, hurt gig workers by paying them lower wages.

High Shear Processing of Expanded Vermiculite Filled Polymer Composites: Particle Size Effect on Flexible Composites

Published: January 2023

Filler dispersion is an important issue for polymer-based composites. Fillers can be dispersed by melt or solution processing methods. Solution-based mixing offers various combinations including ultrasonication, mechanical stirring, or high shear mixing. Planetary high shear mixing is a simple method with high dispersion performance. Dispersion and wetting of the fillers are provided by not only planetary shear movement of the mixer but also by the decrease in viscosity of the polymer phase because of high shear. Although that is advantageous for the dispersion of nanofillers, it might be challenging for the particles that have morphology with loosely bonded layers. To observe the effects of high shear mixing on expanded vermiculite (VMT) filled styrene-[ethylene-(ethylene-propylene)]-styrene (SEEPS) flexible composites, two different VMTs were used with different particle sizes at various VMT ratios from 1 to 30 wt%. Morphological, structural, thermal, mechanical properties, flame spread character of the composites, and viscosity of the solutions were analyzed. From morphological analysis, high shear mixing was found to be effective in terms of decreasing particle size and filler dispersion. While mechanical properties showed decrease, thermal stability, and flame retardancy of the composites increased.

Published: January 2023

The expected value of the maximum value of the rectangular E-field is important in radiated susceptibility testing in a reverberation chamber. In this paper, different forms of equations for the maximum-to-mean ratio of the rectangular E-field are reviewed. Important derivations are summarized and detailed. It is interesting to note that some series which could be difficult to deal with from mathematics could be solved efficiently from physical point of view. The relationship between the independent sample number N and the parameters in generalized extreme value distribution is also given.
A Compact High Gain Wideband Metamaterial Antenna for Sub-6 GHz Applications
Authors: Abbas Ahmed A. , Samet Balasem S.
Published: January 2023

This paper presents a design of high gain wideband antenna with metasurface for sub-6 GHz applications. The antennas at sub-6 GHz have a narrow bandwidth and low gain with a narrower axial ratio (AR). Hence, antennas combined with metamaterials are proposed to overcome these issues. The proposed metasurface antenna is designed with the implementation of W-shape transmission lines within the vias. The proposed antenna with metasurface is simulated using CST software and then fabricated on the FR4 substrate with (er=4.4 and h=1.6 mm). The antenna performance achieved a wide bandwidth of 85% and operates at 2 GHz to 5 GHz. A compact size of 45% is achieved with a high gain of 7.12 dB. The proposed antenna is suitable to be used in future sub-6 GHz applications.
