Coherent Radio Emission from “Main-sequence Radio Pulse Emitters”: A New Stellar Diagnostic to Probe 3D Magnetospheric Structures
Authors: Das Barnali , Chandra Poonam , Petit Véronique
Published: October 2024

Main-sequence radio pulse emitters (MRPs) are magnetic early-type stars that produce coherent radio emission observed in the form of periodic radio pulses. The emission mechanism behind this is the electron-cyclotron maser emission (ECME). Among all kinds of magnetospheric emission, ECME is unique due to its high directivity and intrinsically narrow bandwidth. The emission is also highly circularly polarized and the sign of polarization is opposite for the two magnetic hemispheres. This combination of properties makes ECME highly sensitive to the three-dimensional structures in the stellar magnetospheres. This is especially significant for late-B and A-type magnetic stars that do not emit other types of magnetospheric emission such as Hα, the key probe used to trace magnetospheric densities. In this paper, we use an ultra-wideband observation (0.4–2 GHz) of a late B-type MRP HD 133880 to demonstrate how we can extract information on plasma distribution from ECME. We achieve this by examining the differences in pulse arrival times (“lags”) as a function of frequencies and qualitatively comparing those with lags obtained by simulating ECME ray paths in hot stars’ magnetospheres. This reveals that the stellar magnetosphere has a disk-like overdensity inclined to the magnetic equator with a centrally concentrated density that primarily affects the intermediate frequencies (400–800 MHz). This result, which is consistent with the recent density model proposed for hotter centrifugally supported magnetospheres, lends support to the idea of a unifying model for magnetospheric operations in early-type stars, and also provides further motivation to fully characterize the ECME phenomenon in large-scale stellar magnetospheres.

We present the most precise measurements to date for the spatial extension and energy spectrum of the γ-ray region between a pulsar’s wind nebula and the interstellar medium, better known as the halo, present around Geminga and PSR B0656+14 (Monogem) using ∼2398 days of >1 TeV data collected by the HAWC observatory. We interpret the data using a physically motivated model for the diffuse γ-ray emission generated from positrons and electrons (e±) injected by the pulsar wind nebula and inverse Compton scattering with interstellar radiation fields. We find the morphologies of the regions inside these halos are characterized by an inhibited diffusion that are approximately three orders of magnitudes smaller than the Galactic average. We also obtain the e± emission efficiencies of 6.6% and 5.1%, respectively, for Geminga and Monogem. These results have remarkable consequences for the study of the particle diffusion in the region between the pulsar wind nebulae and the interstellar medium, and for the interpretation of the flux of positrons measured by the AMS-02 experiment above 10 GeV.
Follow-up Observations of Apparently One-off Sources from the Parkes Telescope
Authors: Zhang Songbo , Yang Xuan
Published: October 2024

A small fraction of fast radio bursts (FRBs) have been observed with multiple bursts, whereas most Galactic sources emitting radio pulses are known to repeat. Here we present the results of follow-up observations of two FRBs and four rotating radio transients (RRATs). Among these, only one RRAT has been observed with repeating pulses, with an estimated period of around 1.297047 s. For comparison, we reanalysed the Parkes archival follow-up observations in CSIRO’s data archive for all apparently one-off sources discovered by the Parkes telescopes, including 13 RRATs and 29 FRBs. In total, 3 RRATs are suggested to be repeaters, but no repeating signals were detected from the other sources. Reporting details of the nondetection observations for the apparently one-off sources would help investigate their origins, and catastrophic scenarios are worth proposing for both extragalactic and Galactic sources.

Authors: Lebanova Hristina , Petrova Elina , Stoev Svetoslav
Published: October 2024

A retrospective, cost-of-illness study aimed at identifying direct healthcare costs of vulvar, vaginal, anal, penile, and H&N cancers in Bulgaria from the payer perspective and calculating indirect costs and the associated years of life lost was carried out. Costs’ data were obtained from the National Health Insurance Fund from January 2018 to December 2020. Years of life lost were calculated based on the country and gender-specific life expectancy. The human capital approach was used to evaluate the indirect costs. The total treatment costs for 3623 patients were EUR 10,875,771 (2018), EUR 11,922,521 (2019) and EUR 12,329,463 (2020). The costs associated with radiotherapy and drug acquisition and administration accounted for the majority (75–78%) of total healthcare costs. A cumulative loss of approximately 33,299 life years occurred between 2018 and 2020. The costs of productivity losses were estimated at EUR 14,113,265.

Published: October 2024

Hemipilia zhuxiensis (Orchidaceae), is a new species discovered in the Shibali Long Canyon National Nature Reserve, Zhuxi County, Hubei Province, China. It is morphologically similar to Hemipilia henryi and Hemipilia crassicalcarata, but differs in having an oblong, simple labellum with a slightly involute margin, an upcurved apex, and a spur shorter than the ovary. Molecular phylogenetic analyses, using nuclear (nrITS) and plastid (combined matK, psaB, psbA-trnH, rbcL and trnL-F) DNA sequences, confirm that H. zhuxiensis is closely related to Hemipilia henryi and Hemipilia crassicalcarata, supporting its recognition as a new species in the H. section Hemipilia as defined by Tang et al. (2015).
A new species of the pill millipede genus Rhopalomeris Verhoeff, 1906 (Diplopoda, Glomerida, Glomeridae) from Myanmar, and notes on Rhopalomeris carnifex (Pocock, 1889)

Published: October 2024

The taxonomy of the pill millipede genus Rhopalomeris Verhoeff, 1906, which is restricted to Indochina and currently comprises six described species, is refined and updated. An integrative taxonomic approach was employed that combines morphological examination with DNA barcoding using the cytochrome c oxidase subunit I (COI) gene for species identification and delineation. The first objective was to confirm the identity of Rhopalomeris carnifex (Pocock, 1889), a charismatic species known as the “candy pill millipede” due to its vivid coloration, based on specimens collected near the type locality in Myanmar. The second objective was to describe a new species, Rhopalomeris nigroflava Likhitrakarn, sp. nov., discovered in Linno Gu, Kayin State, Myanmar. This new species is distinguished by its small body size (5.1–9.7 mm long) and yellow body with contrasting brown to blackish markings on certain terga. In addition, the position of the telopod syncoxital lobe relative to the lateral syncoxite horns separates it from other Rhopalomeris species. The interspecific divergence between R. nigroflava Likhitrakarn, sp. nov. and other congeners ranges from 10.85% to 16.13%, based on uncorrected COI p-distances, while the intraspecific divergence was 0%–7.44%. A distribution map of and a revised identification key to all known species of Rhopalomeris are also provided.

Cinquante ans après la mort de Jean Daniélou, où en est la question du judéo-christianisme ?
Authors: Burnet Régis
Published: October 2024

Le livre Théologie du Judéo-christianisme de Jean Daniélou, publié en 1958, a remporté un grand succès, bien qu’il fût reçu différemment de l’intention originale de l’auteur. Conçu comme une réponse à Harnack et une théologie du christianisme d’origine juive, il a été perçu comme une invitation à retrouver les racines juives du christianisme. Cinquante ans après, la perspective sur le judéo-christianisme a significativement changé. Les recherches modernes ont remis en question la vision téléologique de Daniélou, se concentrant plutôt sur le rôle des changements sociaux dans la formation des identités religieuses. Bien que les théories de Daniélou soient maintenant fort délaissées, il serait cependant utile de renouer avec l’intuition première du Cardinal : peut-on reconstruire la théologie des premiers chrétiens d’origine juive ?
Dévoilement, prophétisme et nourriture. À propos d’Ézéchiel et de l’Apocalypse
Authors: Arbib Dan
Published: October 2024

Les deux textes de l’Apocalypse 10, 8-9 et Ézéchiel 2, 8-3, 3 (§ 1) ouvrent l’espace d’un double paradoxe lié au caractère pécheur et négateur de la consommation (§ 2) ; mais ce paradoxe trouve sa résolution dans une analytique à la fois nietzschéenne et levinassienne du se-nourrir (§ 3). S’ensuit alors une anthropologie qui est surtout prophétologie (§ 4) et qui met le dévoilement au cœur de toute parole (§ 5).

La contribution « Les topographies et généalogies nostalgiques du mime Farina (1883-1943) » met en lumière le parcours d’un mime, méconnu aujourd’hui, au début du xx e siècle. La décadence de la pantomime et le regret de son âge d’or forment des topoï de débats littéraires et journalistiques à l’époque où Farina apparaît comme un être en asynchronie. Son ambition directrice, véritable rétrotopie, est la résurrection du Théâtre des Funambules. Il s’inscrit dans des généalogies mythographiques de mimes et juxtapose le Montmartre réel avec la « patrie de Pierrot ». Ses activités et écrits témoignent de tensions opposées dans la pantomime en France entre le xix e siècle et la réforme initiée par Étienne Decroux, ainsi que de la nostalgie d’un monde moins complexe face à une réalité artistique et sociétale agitée par la déconstruction de codes.

La contribution « La plénitude du passé. L’archéologie du théâtre du xx e siècle » analyse quelques visions des temps historiques dans les cultures du théâtre au xx e siècle, mesurant et discutant les liens de distance et de désir qu’inspirent les attraits et les regrets pour les traditions et les sources des métiers de la scène. En comparant le sens du temps et de la mémoire des hommes de théâtre (Meyerhold, Copeau, Artaud) aux regards de l’observation ethno-anthropologique sur les actes et les symboles, on cherche à marquer les termes originaux acquis par cette dialectique pour Grotowski et pour d’autres expériences vers la fin du siècle.
La Nostalgie au théâtre
Authors: Frantz Pierre
Published: October 2024

« Beaumarchais, ouverture à la nostalgie » : Entre l’Ancien Régime et la Révolution, entre regards sur le passé et fondation de l’avenir, le théâtre de Beaumarchais s’est fait une place singulière. D’autres, avant lui, avaient ouvert dans la comédie des voies à la sensibilité moderne, mais Beaumarchais fait preuve, dans Le Mariage de Figaro et dans La Mère coupable , d’une originalité profondément novatrice. Le cadre générique de la comédie, enrichi par le drame, puis le drame lui-même font une place nouvelle au théâtre, à l’expression de la nostalgie. Celle-ci se charge d’histoire en transformant le temps théâtral. Si le présent absolu de la comédie classique n’était guère propre à dire l’histoire, Beaumarchais ouvre la scène au temps historique à travers la médiation de la nostalgie, c’est-à-dire de la subjectivité.

Innovative approaches of a time-fractional system of Boussinesq equations within a Mohand transform
Authors: Alesemi Meshari
Published: October 2024

This paper investigated the application of analytical methods, specifically the Mohand transform iterative method (MTIM) and the Mohand residual power series method (MRPSM), to solve the fractional Boussinesq equation. Utilizing the Caputo operator to manage fractional derivatives, these semi-analytical approaches provide accurate solutions to complex fractional differential equations. Through convergence analysis and error estimation, the study validated the efficacy of these methods by comparing numerical solutions to known exact solutions. Graphical and tabular representations illustrated the accuracy of the proposed methods, highlighting their performance for varying fractional orders. The findings demonstrated that both MTIM and MRPSM offer reliable, efficient solutions, making them valuable tools for addressing fractional differential systems in fields such as applied mathematics, engineering, and physics.
Accommodements religieux
Authors: Bizien Filippi Myriam
Published: October 2024

À partir des années 1960, à un moment de croissance de la population immigrée en France et de réception du concile Vatican II, des mouvements catholiques d’éducation populaire « à la gauche du Christ » – la JOC-F, l’ACE puis le scoutisme catholique « de France » – s’ouvrent aux jeunes musulmans issus de l’immigration maghrébine et turque pour affirmer ou réaffirmer leur ancrage dans les milieux populaires. Cette rencontre entre mouvements catholiques et jeunes musulmans, née dans le contexte intellectuel du tiers-mondisme, est peu à peu analysée en termes de dialogue interreligieux. À la croisée de l’histoire religieuse et de l’histoire sociale, et grâce à l’analyse des archives des mouvements et au recours à l’histoire orale, c’est donc un aspect méconnu du dialogue interreligieux en France qui se dessine dans cet ouvrage : une rencontre sur le terrain, dans les quartiers populaires, loin des réunions officielles entre dignitaires religieux ou intellectuels.
Dirceu Lino De Mattos: Um Geógrafo Da Revolução Paulista
Authors: Bezerra Rogério Silva
Published: October 2024

O artigo apresenta aspectos da história pessoal, familiar e do percurso formativo do fundador da Cátedra de Geografia Econômica da Faculdade de Economia e Administração da USP (FEA-USP), professor Dr. Dirceu Lino de Mattos. Além de publicar diversos títulos e de participar de alguns dos maiores trabalhos de geografia no Brasil entre as décadas de 1950-1970, Dirceu foi por duas vezes presidente nacional da Associação dos Geógrafos Brasileiros (AGB) e diretor da FEA também por duas oportunidades, tornando-se uma das figuras de maior visibilidade da primeira geração de geógrafos da USP. Oriundo de uma família de lavradores pobres do interior paulista, ele teve uma trajetória marcada pela ascensão social e política familiar, ligada ao campo profissional da educação e à docência. Dirceu combateu na Revolução Constitucionalista paulista de 1932, junto com seus irmãos, entre os quais, o mais famoso, Juvenal Lino de Mattos - o “Senador Lino de Mattos” – que, antes de ocupar vaga no senado, foi Deputado Constituinte e Prefeito de São Paulo. Dirceu teve contato com eminentes figuras políticas da vida nacional, como Adhemar de Barros, Luiz Carlos Prestes, Jânio Quadros, João Goulart, Marighella, dentre outros. No campo profissional, trabalhou institucionalmente com intelectuais como Sérgio Buarque de Holanda, Alice Canabrava e Delfim Neto, na fundação do Instituto de Estudos Brasileiros (IEB). Na geografia, Dirceu participou ativamente como sócio das atividades da Associação dos Geógrafos Brasileiros (AGB), instituição em que ocupou a presidência por duas vezes, além de coordenar a organização de várias atividades e encontros. Realizou pesquisas em extremos territoriais nacionais, como no Pará e na divisa com Uruguai, mapeando quadro natural e humano. No presente artigo, enfocamos a vida familiar e trajetória formativa, do nascimento, até o momento em que concluiu seu curso de graduação na USP e se filiou à AGB. O artigo utiliza uma metodologia que inclui entrevistas com membros da família e pessoas do universo profissional, documentos, fotos e outros materiais sobre a história de Dirceu. Conclui que a trajetória de vida do eminente geógrafo da USP dos anos 1950-70 se coadunou com a própria história política paulista da primeira metade do século XX, em sua passagem do mundo oligarca e rural ao urbano-industrial, percorrendo um trajeto que foi da “revolução armada” no campo de batalha em 1932 à “revolução dos livros” e dos professores da USP nas décadas seguintes.
Contrôler et diriger une banque d’émission coloniale en temps de crise : l’État et la Banque de La Réunion à la Belle Époque
Authors: Clermidy Arnaud
Published: October 2024

En tant que banque d’émission coloniale, la banque de La Réunion était soumise à un contrôle étatique spécifique. Très dépendante de l’économie sucrière, elle traversa à la fin du xixe siècle et au début du xxe siècle des difficultés qui mirent son existence en péril et incitèrent l’autorité de tutelle à renforcer son contrôle. L’administration nomma des directeurs chargés de piloter la gestion de l’établissement en imposant une feuille de route précise : constitution de réserves, respect strict du statut (notamment de la convertibilité des billets), priorisation de certains types d’opérations. Effectués parfois au détriment de l’économie locale que la banque d’émission était pourtant supposée favoriser, ces choix suscitèrent questions et critiques dans la population locale.
L’opium au Việt Nam en situation coloniale (1899-1946)
Authors: Clare Thomas
Published: October 2024

L’opium jouait un rôle de premier plan dans l’économie et les finances de l’Indochine française. Le produit de sa vente procurait au budget général le quart de ses recettes, contribuant très largement au développement de la colonie. On comprend dès lors la nécessité pour l’administration coloniale de rendre compte de manière chiffrée de la place de l’opium dans ses finances, et de l’étendue de sa consommation sur le territoire. Mais il reste à appréhender la réalité d’un marché qui échappait très largement aux données statistiques. En dépit de son rôle essentiel dans le financement de la colonie, le « monopole » n’était que théorique, et était menacé par une contrebande massive et endémique, qui invite à réévaluer la place de la drogue dans l’économie et la société coloniale indochinoise.
Il Digital Market Act (Reg.to UE n. 2022/1925) ed il nuovo approccio alla regolazione ex ante dell’abuso di posizione dominante
Authors: Sporta Caputi Francesco
Published: October 2024

La gestione dei cd. Big Data pone i gestori di piattaforme digitali in una posizione di iper-dominanza sul mercato rispetto alla catena del valore dei dati «originari ed aggregati» che talvolta sfocia in condotte anticoncorrenziali di tipo escludente, legante o di self preferencing riconducibili al genus dell’abuso di posizione dominante (caso Google Shop e caso Amazon FBA) vietato dall’art. 102 TFUE. Il recente Regolamento UE n. 2022/1925 relativo ai mercati equi e contendibili nel settore digitale (c.d. Digital Market Act) costituisce l’occasione per verificare se gli obblighi comportamentali imposti ai gatekeeper siano idonei a prevenire o arginare ipotesi di abuso di posizione dominante.
Economia circular como alternativa à economia linear: desafios e contribuições à sustentabilidade
Authors: Marcio Cruz Paulo , Ferrer Gabriel Real , Antunes de Souza Maria Cláudia da Silva
Published: October 2024

O modelo econômico linear de produção-consumo-descarte está atingindo seu limite. Um dos caminhos para o enfrentamento desse problema é por meio de um modelo econômico circular, que associa o crescimento econômico a um ciclo de desenvolvimento, que preserva e aprimora o capital natural, otimiza a produção e administração dos recursos. A iminente exaustão de vários recursos naturais, aliada aos problemas decorrentes do excesso de resíduos gerados por um consumo dessa magnitude, impõe ao meio jurídico um novo modo de ver a economia, traduzindo como novo paradigma de negócios a economia circular. Sendo assim, tem-se como objetivo conceituar, caracterizar e tratar da base jurídica da economia circular no Brasil e no exterior; especialmente, a aplicação dos princípios da economia circular nas matrizes energéticas. Sendo relevante tratar desse tema, pois tanto para o meio acadêmico quanto social é fundamental levar ao conhecimento as alternativas viáveis para a economia que ainda, se identifica como extremamente predatória, pouco solidária e insuficientemente preocupada com as causas e efeitos socioambientais. Quanto a metodologia, tanto na fase de investigação quanto na fase de relatório dos resultados, o método empregado foi o indutivo.

Effects, Challenges, and Issues for Integration of Solar PV Systems to the Grid
Authors: Ponnambalam Suriya , M. K. Ilampoornan
Published: October 2024

This chapter applies a dynamical electrical array re-configuration (EAR) strategy on the photovoltaic (PV) generator of a grid-connected PV system based on a plant-oriented configuration, in order to improve its energy production when the operating conditions of the solar panels are different. The EAR strategy is carried out by inserting a controllable switching matrix between the PV generator and the central inverter, which allows the electrical reconnection of the available PV modules. As a result, the PV system exhibits a self-capacity for real-time adaptation to the PV generator external operating conditions and improves the energy extraction of the system. Experimental results are provided to validate the proposed approach.

Online Learning Challenges Encountered by University Students Amidst the COVID-19 Pandemic: A Systematic Review of Digital Divide Perspective
Authors: Alikhan Sakeena , Sritharan T.
Published: October 2024

The COVID-19 has required a rapid conversion from the conventional learning to online learning, revealing and intensifying the digital inequality amongst university pupils. The primary objectives of this systematic review study are to identify the digital divide challenges encountered by university students in online learning amidst the COVID-19 pandemic and to understand the underlying reasons contributing to these challenges. This study focuses on empirical research published between 2020 and 2023. The review utilized the seven phases of systematic review recommended by the Evidence for Policy and Practice Information and Co-ordinating Centre. A comprehensive Scopus and Web of Science search was undertaken using word string "higher education/university education/university students", "online learning/distance learning," "COVID-19/pandemic,” “digital divide/digital inequality/digital exclusion," and, and the initially 190 articles were extracted.The criteria for inclusion restricted the number of publications that were examined to a total of 11. The analysis reveals two primary categories of digital divide challenges: the first-level digital divide, characterized by limited access to essential digital devices and internet connectivity, and the second-level digital divide, which relates to varying levels of digital competency among students.Key factors contributing to these challenges include financial constraints, geographical disparities, and inadequate technological infrastructure. Students from economically disadvantaged backgrounds and rural areas faced significant obstacles in engaging with online learning platforms, leading to adverse academic outcomes. Strategies for bridging the digital divide should be implemented in collaboration with educational institutions, government agencies, and private sector stakeholders. These strategies should focus on the enhancement of technological infrastructure, the provision of financial support, and the provision of digital literacy training programs. The review highlights the importance of understanding the digital divide in shaping future educational practices and policies, aiming to create a more inclusive and resilient higher education system in the post-pandemic era. By addressing the identified challenges, institutions can empower all students to succeed in an increasingly digital learning environment.

Hidradenitis Suppurativa (HS) is a chronic, Skin Immune-Mediated Inflammatory Disease (sIMID), with a high impact on Quality of Life (QoL). Data on clinical management, comorbidities, psychosocial burden, and psychiatric disorders in paediatric patients with HS is scarce. The aim of our study was to compare clinical characteristics and Patient-Reported Outcome Measures (PROMs) for Health-Related Quality of Life (HRQoL) in adult and paediatric patients with HS. Data were collected on 601 patients with HS, 60 of whom (10.0%) were paediatric. The psychological and HRQoL impact was generally higher in adults than in children, but it was noteworthy also in paediatric patients. Early diagnosis and interventions based on education for the patients and their families and psychological support are the key to optimal disease management and adherence. Our study underlines the need for screening for HS-associated psychiatric disorders and for using age-specific tools to evaluate HRQoL. A multidisciplinary approach involving several specialists is needed, as well as liaison with primary care specialists to improve care, and management of comorbidities and psychological issues in patients with HS.
The Relationship of Preseason Upper Extremity Function, Pain and Training on Normalized DIII Collegiate Swimming Performance
Authors: Tate Angela , Woznicki Laruen , Strouse Gregory , Wisseman Darrell , Thomas Stephen
Published: October 2024

Context:

Shoulder injuries comprise the largest proportion of swimming injuries and there is a large percentage of swimmers participating with pain. Therefore, it is assumed that shoulder pain decreases performance, but studies have not compared collegiate swimmers' performance with and without pain.

Objectives:

1) Determine if individual swimmer's shoulder pain and function are associated with a change in normalized swimming performance over a season.2) Determine if differences in normalized swimming performance exist among 3 collegiate teams. 3) Qualitatively describe and compare team's training regimes.

Design:

Cross sectional study

Setting:

Swimmers completed pre-(T1) and post-season (T2) surveys including pain ratings and shoulder function using the Kerlan-Jobe Orthopaedic Clinic (KJOC) shoulder and elbow questionnaire. Swimming times were obtained from published meet results. Coaches reported training programs through interviews and tracking logs.

Participants:

52 NCAA Division III swimmers from 3 teams

Main Outcome Measures:

Stepwise linear regression was used to determine if pain and function related to performance. Team demographics and normalized swimming performance (reduction in time per lap from season's beginning to end) were compared with ANOVAs with post-hoc tests.

Results

Initial KJOC scores, but not pain, related to individual swimming performance. Differences in team performance were found (p=0.006), with Team 3 having greatest reduction in time (1.01 sec/lap), lower percentage of females, a more experienced coach and a periodization schedule with large increases and decreases in yardage. There was a main effect (p=0.043) for baseline demographics with Team 3's swimmers being taller and having longer competitive experience.

Conclusions

The initial KJOC score predicting swimming performance improvement demonstrates the need for athletic trainers to prioritize enhancement of pre-season function. Endurance training induced hypoalgesia and motivation may explain the lack of effect of shoulder pain on performance. Further research is needed to elucidate optimal periodization and dryland training.
The Relationship Between Active Coping Skills and Self-Reported Knee Function in Individuals with Anterior Cruciate Ligament Reconstruction
Authors: Bennett Autumn L. , Bartels Amelia , Harkey Matthew , Covassin Tracey , Baez Shelby E. , Genoese Francesca M.
Published: October 2024

Context:

Individuals with anterior cruciate ligament (ACL) injury commonly experience injury related stressors which can adversely impact subjective knee function after ACL reconstruction (ACLR). Due to the positive effect of active coping skills on perceived stressors, use of such strategies may influence clinical outcomes in individuals with ACLR, such as self-reported knee function. However, it is unknown whether active coping skills are associated with self-reported knee function in this population.

Objectives:

Examine the relationship between active coping skills and self-reported knee function in individuals with ACLR.

Design:

Cross-Sectional Study

Setting:

Laboratory

Patients or Other Participants:

Forty-five participants (34 females; age=20.0[3.3] years) 4-months to 5-years post-unilateral ACLR (time since ACLR=12.0[16.0] months).

Main Outcome Measure(s):

The Athlete Coping Skills Inventory (ACSI) Confidence and Achievement Motivation (ACSI Confid), Goal Setting/Mental Preparation (ACSI Goal/Prep), and Coping with Adversity (ACSI Coping) subscales were used to measure active coping skill facets. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was used to measure self reported knee function across 5 subscales: pain (KOOS-Pain), symptoms (KOOS-Symptoms), activities of daily living (KOOS-ADL), quality of life (KOOS-QOL), and sports/recreation (KOOS-Sport). Partial Spearman's correlations were used to examine relationships between active coping skills and self-reported knee function after controlling for time since ACLR and age.

Results:

Moderate positive correlations were observed between the ACSI Confid and KOOS Pain (r=0.493, P=0.001), ACSI Confid and KOOS-QOL (r=0.505, P<0.001), ACSI Confid and KOOS-Sport (r=0.422, P=0.007), and ACSI Goal/Prep and KOOS-Pain (r=0.441, P=0.004). Weak positive correlations were observed between the ACSI Goal/Prep and KOOS-ADL (r=0.373, P=0.018) and ACSI Goal/Prep and KOOS-QOL (r=0.374, P=0.017).

Conclusions:

Individuals with ACLR who exhibited greater active coping skill facets reported better knee-related function. Assessing active coping skills among individuals with ACLR and poor self-reported knee function may provide clinicians with insight into the role of coping in perceived function and potential treatment approaches.
Innovation capabilities and performance of small and medium-sized enterprises in Indonesia
Authors: Isa Muzakar , Nurohman Yulfan A. , Qurniawati Rina S.
Published: October 2024

Orientation: Entrepreneurial orientation (EO), knowledge management (KM), human resource management (HRM) and knowledge sharing (KS) are important aspects in driving innovation capabilities (IC) to improve organisational performance (OP).Research purpose: The purpose of this research was to analyse the mediating effect of IC on individual EO, KM, HRM and KS and small and medium-sized enterprises (SMEs) performance.Motivation for the study: The fluctuation in batik business performance can be attributed to a lack of studies that examine the dynamic capability perspective in the context of batik SMEs in developing countries.Research design, approach and method: A quantitative approach was used for this study. A structured self-administrative measuring instrument was employed to collect the data. A non-probability sample of 297 participants was obtained. The collected data were then analysed using SmartPLS3 software.Main findings: Innovation capabilities have been verified to significantly mediate the relationship between HRM and KS on OP. Innovation capabilities mediated the relationship between KS and OP in a negative direction, whereas previous studies indicate a positive direction.Practical/managerial implications: Entrepreneurial orientation has the most prominent role in OP in batik SMEs. An EO allows business actors to optimise their creativity and innovation to develop ideas, which helps maximise the growth of OP in SMEs.Contribution/value-add: This study’s results support the concept that EO develops various skills, from managing uncertainty to tolerating risk and forming strong entrepreneurial abilities to improve business performance.

Background: The rehabilitation team, consisting of physiatrists, physical and occupational therapists, and speech pathologists, faces heightened risk of COVID-19 exposure because of treatment practices in rehabilitation settings.Aim: The study aimed to assess the knowledge, practices and attitudes of rehabilitation professionals in treating COVID-19 patients and to determine potential associations with respondents’ demographic factors (e.g., age, gender, type of profession).Setting: The study was conducted in the Philippines.Methods: This cross-sectional study was conducted from June 2021 to July 2021. Researchers employed snowballing and purposive homogenous convenient sampling methods. Participants completed a 31-item online questionnaire via Google Forms.Results: A total of 410 rehabilitation professionals participated in the study. The total mean scores for knowledge, practices and attitudes are 41.14 ± 3.16, 104.54 ± 33.65 and 37.13 ± 3.55, respectively which were considered adequate. However, only 9.8% (n = 40) professional was actively treating COVID-19 patients with analysis of variance indicated that age, type of profession and gender did not significantly impact COVID-19 knowledge. However, age (p = 0.005) and type of profession (p = 0.004) were found to influence COVID-19 practices, with physiatrists exhibiting higher adherence. There was a strong positive correlation between age and positive COVID-19 attitudes (p  0.000).Conclusion: Filipino rehabilitation professionals have positive attitude, adequate knowledge and skills about COVID-19.Contribution: The study provides information to modify training courses and curricula to further improve the knowledge and practices related to COVID-19.
