Objective. To identify predictors for Simplified Disease Activity Index (SDAI) remission in established rheumatoid arthritis (RA) and to develop a predictive score for remission. Methods. Prospective 12-month observational study in ninety active RA receiving their first TNF-α inhibitor. Standard assessments consisted of disease activity scores (DAS28-ESR, SDAI) and immune parameters (total rheumatoid factor, RF; IGA-RF; anti-cyclic citrullinated peptide antibodies, ACPA). The primary outcome measure was SDAI remission (≤ 3.3) at 12 months. Univariate and multivariate logistic regression models were used to estimate association between baseline variables and SDAI remission. Results. 39.7% RA achieved remission, while 56.8% low disease activity. Significant association between SDAI remission and RA-onset before 50 (p = 0.000), history <5 years (p = 0.000), stage (p = 0.000), class I and II Steinbroker functional status (p = 0.022), HAQ-DI≤2 (p = 0.034), CRP ≤ 20mg/l (p = 0.041), IgA-RF ≤ 20 IU/ml (p = 0.002), ACPA ≤ 40 IU/ml (p = 0.047), concomitant DMARDs (p = 0.003) were identified. Four parameters independently predicted 12-month remission (age at onset under 50, RA duration <5 years, ACPA≤40 IU/ml, IgA-RF ≤ 20 IU/ml) as demonstrated by multivariate logistic regression (p<0.05), making correct prediction in 84.4% patients. Furthermore, the remission score correctly classified 90.6% RA, while the transformed simplified version up to 89.4% cases. Gender, clinical parameters and ESR were not predictors for treatment response (p > 0.05). Conclusion. SDAI remission can be predicted in established RA using a score based on age at onset, disease duration, titers of ACPA and RF isotype A. Such a simplified score may help clinicians to manage remission in RA patients according to the current treatment guidelines.

Objective. Our aim was to investigate whether two ERAP1 gene variants, rs30187 and rs27044, influence the clinical characteristics of ankylosing spondylitis (AS) (the age of onset and the type of articular manifestations - axial or mixed) in Romanian patients. Methods. We studied 94 AS patients and 139 healthy controls. The method used for genotyping the two non-synonymous single nucleotide polymorphisms (SNPs) was real-time polymerase chain reaction. Association tests were carried out using PLINK 1.07 software. We analyzed separately the subgroups of AS patients with early onset (age <30 years) and late onset (age > 30 years), as well as the subgroups of patients with axial manifestations and mixed manifestations (axial and peripheral). Results. Significant association between ERAP1 polymorphisms and AS is only present for patients who experienced an early onset (p = 0.04 for rs30187 and p = 0.007 for rs27044) and not for those with late onset (p = 0.32 for rs30187 and p = 0.29 for rs27044). Polymorphism rs30187 is associated only with the axial form of AS (p = 0.02), while rs27044 is associated only with the mixed form of the disease (p = 0.02). Conclusions. Our findings demonstrate a consistent association between the studied ERAP1 gene SNPs and certain phenotypic characteristics of AS, suggesting that these gene variants may influence the AS onset and the presence of axial or mixed manifestations of AS.

Systemic lupus erythematosus (SLE) and periodontal disease (PD) are two chronic inflammatory diseases that share common pathogenetic mechanisms. Therefore, it is thought that a correlation between the two pathologies might exist. PD itself, when not associated with SLE, does not cause major cardiovascular events, but it contributes to the development of atherosclerosis, which is the major cause of death among patients with SLE. This article aims to summarize the available literature concerning the association between these two disorders (PD prevalence in patients with SLE, correlations between periodontal damage and SLEDAI activity score), to present the main mechanisms by which the two pathologies affect the cardiovascular system and to evaluate the impact of SLE corticosteroid therapy on periodontal tissue.

Rheumatoid arthritis (RA) is a common autoimmune systemic inflammatory disease with still unknown cause. A robust hypothesis for the occurence of the disease is the result of an environmental exposure in a genetically susceptible individual. The risk of RA varies by ethnicity: the majority of the Caucasian populations reported a prevalence of 0.5 to 1% for this disease; higher prevalences were observed in American Indian tribes and lower ones, in countries of Africa and Asia. This regional variation in the prevalence of RA sustains the involvement of both genetic and enviromental factors in the occurence of this condition.

Regarding the pregnancy outcome in patients with Rheumatoid Arthritis (RA), most concerns are linked to pharmacological therapies. In order to manage the disease and obtain a favourable outcome of the pregnancy, there are several remissive or biological therapies that may be used, with minimal precautions. The anti-rheumatic drugs that may be used in RA are classified into 4 pregnancy risk categories according to the risk of inducing fetal injury: minimal risks, medium risks, high risks, and unknown risks. For many biological therapies, the lack of extensive studies is limiting the therapeutic recommendations in this sensitive area; recommendations are coming from experts in this field. However, if the preconceptual period and all the pregnancy conducts comply with the general recommendations, we may conclude that medication and pregnancy in rheumatoid arthritis may be combined with minimal risks.

Introduction. The relationship between periodontal disease (PD) and rheumatoid arthritis (RA) is currently only partially known, both being chronic multifactorial diseases that may share common pathogenic mechanisms and etiological factors. In a previous meta-analysis we concluded that patients with RA are more commonly affected by PD and develop more severe forms of the disease, compared to the general population. Objectives. The current study aimed to assess the degree of periodontal damage and oral hygiene on a group of patients diagnosed with RA. Methods. The study was conducted on a group of 30 patients, 6 sextants being assessed in each patient (180 potentially evaluable sextants). Establishing the degree of periodontal damage and oral hygiene was achieved by determining the Community Periodontal Index of Treatment Needs (CPITN) and Oral Hygiene Index (IHB, also known as OHI). Results. The mean CPITN score/sextant was 1.92. After clinical examination we found 10 edentulous sextants that could not be evaluated. As a result of the distribution of the scores on all the 170 evaluable sextants, we obtained: CPITN 0 – 11.1%, CPITN 1 – 23.6%, CPITN 2 – 32.4%, CPITN 3 – 27.6%, CPITN 4 – 5.3%. After analyzing the oral hygiene index the mean value we found was 16. Distribution of IHB intervals was: IHB 0-12 (40%), IHB 13-24 (53.3%), IHB 25-36 (6.6%). Discussion and conclusions. Comparing our results to data from the literature, in our group of patients with RA the only CPITN index criteria significantly increased, compared to the healthy population, were gingival bleeding on probing and the number of periodontal pockets with 4-5.5 mm depth.

Introduction. Hypertrophic osteoarthropathy (HOA) is a rare, hereditary disease characterized by clubbing and new bone formation in the periosteal region that may be associated with joint pain, cutaneous abnormalities, seborrhea or hyperhydrosis. Juvenile idiopathic arthritis (JIA) is one of the most frequent chronic diseases with childhood onset, patients develop inflammatory joint pain and extra-articular manifestations with imunologic substrate. The association of the two diseases is very rare. 24 years old patient related disease onset at the age of 14 with arthritis of proximal interphalangeal joints (PIP), knees and right ankle. He is diagnosed with oligoarticular form of juvenile idiopathic arthritis. He receives Methotrexate, Suphasalazyne and association of the two, but after 5 years biological therapy with Etanercept is started. Later on, repeated physical examination revealed digital clubbing, non-painful enlargment of hands and feet with sweaty teguments. Radiological examination with subperiosteal new bone formation of the distal tibia, the fibula, the radius, the ulna, the metacarpals and the phalanges confirms the suspicion of HOA – pachydermoperiostosis (PDP). Conclusion. Final diagnosis considers both entities. The incomplete form of PDP included hands and feet enlargement with extensive periostitis, palmoplantar hyperhydrosis, but no significant facial changes. The specific treatment for JIA did not influence the evolution of PDP.

An Exegetico-Theological Study of Romans 8:1-8: Toward a Pneumatological-Ecclesiology
Authors: Boaheng Isaac
Published: September 2021

This article focuses on Paul’s teachings on how the believer’s life in the Spirit contrasts the believer’s previous life of sin, with particular reference to Romans 8:1-8. It first employed the exegetical method—comprising contextual analysis, literary analysis, detailed analysis of lexicology (the meaning of words), morphology (the form of words), grammatical function of words (parts of speech), syntax (the relationships of words) and figures of speech—to explore the text. The next step was a systematic theological formulation of pneumatological-ecclesiology based on the results from the exegetical study of the text. The main argument is that the Spirit applies Christ’s salvific work to the believer in a way that does not only put the believer right forensically but also puts him/her right behaviorally. Thus, the believer walking in the Spirit is both justified by the cross and by good deeds performed through the enabling presence of the Spirit. The article contributes to the academic disciplines of systematic theology and biblical studies by exploring what pneumatological-ecclesiology is embedded in the text and applying this formulated theology to the life of the contemporary church, drawing attention to the fact that since the Holy Spirit breathes upon and through the church, the activities of the Spirit in the church should be the plumb line for assessing the nature and conduct of the church. This contribution serves as an effective tool for enhancing ethical and religious renewals in believers in a way that eventually enhances their relationship with God, other humans and the environment.

Authors: Hiraga Kohei , Tatebe Osamu , Kawashima Hideyuki
Published: September 2021

Metadata performance scalability is critically important in high-performance computing when accessing many small files from millions of clients. This paper proposes a design of a scalable distributed metadata server, PPMDS, for parallel file systems using multiple key-value servers. In PPMDS, hierarchical namespace of a file system is efficiently managed by multiple servers. Multiple entries can be atomically updated using a nonblocking distributed transaction based on an algorithm of dynamic software transactional memory. This paper also proposes optimizations to further improve the metadata performance by introducing a server-side transaction processing, multiple readers, and a shared lock mode, which reduce the number of remote procedure calls and prevent unnecessary blocking. Performance evaluation shows the scalable performance up to 3 servers, and achieves 62,000 operations per second, which is 2.58x performance improvement compared to a single metadata performance.

Published: September 2021

The use of a co-creation process within e-learning practices enables learners to live positive experiences as they are more actively involved in the learning process. Starting from this consideration, the paper aims to demonstrate that using a co-creation approach to design a Massive Open Online Course allows amplification of the learning experience as well as the children's knowledge and awareness of digital health literacy issues, particularly of cyber-bullying. To this end, a case study that involves teachers and students from a primary school in Rome has been implemented. To engage students, two participative methodologies (open space technology and storytelling) are used. The results of the case study show a positive impact of the co-creation strategy on both the students' engagement in co-producing the learning content and their awareness and knowledge of the cyber-bullying phenomenon and digital health literacy issues.
Formal Chronicle Analyses and Comparisons: How to Deal with Negative Behaviors
Authors: Pencolé Yannick , Subias Audine
Published: September 2021

The overall context of this paper is the event-based behavior analysis and focuses on modeling and analyzing behaviors of interest involving time information. Any behavior of interest from any time event system is concisely defined as a set of time constrained events that must occur (positive behavior) and a set of time constrained events that must not occur (negative behavior). This article proposes a formal extension of the chronicle formalism that allows for the concise description of positive and negative behaviors. Based on this new formalism, several criteria are introduced, they formally characterize and compare a set of chronicles. A fully proved implementation of the proposed criteria is then described; it relies on the use of polyhedron techniques to solve systems of linear inequalities.

Published: September 2021

Nowadays, bot detection from Twitter attracts the attention of several researchers around the world. Different bot detection approaches have been proposed as a result of these research efforts. Four of the main challenges faced in this context are the diversity of types of content propagated throughout Twitter, the problem inherent to the text, the lack of sufficient labeled datasets and the fact that the current bot detection approaches are not sufficient to detect bot activities accurately. We propose, Twitterbot+, a bot detection system that leveraged a minimal number of language-independent features extracted from one single tweet with temporal enrichment of a previously labeled datasets. We conducted experiments on three benchmark datasets with standard evaluation scenarios, and the achieved results demonstrate the efficiency of Twitterbot+ against the state-of-the-art. This yielded a promising accuracy results (>95%). Our proposition is suitable for accurate and real-time use in a Twitter data collection step as an initial filtering technique to improve the quality of research data.

Published: September 2021

In this case study the authors created and tested a configurable and expandable spatial patterns (SP) description, identification, and application methodology (SPDIAM) and an SP identification algorithm. SPDIAM allows urban planning and design (UPD) practitioners to describe SP in a computerized manner, identify SP automatically and then apply them in the UPD domain. SPDIAM is based on the space syntax (SS) method and normalized spatial and non-spatial measures and can be used with the statistical social, economic, and environmental indicators, which are related to the urban sustainability and spatial capital. The goal of the case study experiment was to proof a concept of SPDIAM and to identify the rules and the values of the measures used for the SP identification. For this City Layout SP was identified in the vector data of 12 European, North American, and African cities. The experiment results confirmed that SPDIAM is appropriate to describe SP and identify them automatically. The use of the normalized measures enables the comparison of different SP and reduces the degree of the subjectivity of the UPD solutions. SPDIAM no longer relies on statistical information but forms SP based on the probabilistic complex modelling of a city, which lets SPDIAM indicate possible directions of SP future transformation. SPDIAM uses the newly offered measures CENTER and URBAN COMPACTNESS INDEX to identify SP automatically and can add quantitative and qualitative improvement to the spatial network analysis tools in Geographic Information Systems.

Published: September 2021

Information systems are pervasive in organizations of all sizes. To use them securely, users must be properly trained. Because of the pervasiveness of information systems the number of scientific publications reporting on user training for secure use of information systems is increasing year by year. To overcome the issue of manually surveying such a vast body of knowledge and to keep up with research trends, we conducted bibliometric mapping of research on user training for secure use of information systems. A total of N = 1955 records published between 1991 and 2019 were retrieved from the Web of Science bibliographic database on 21 November 2019. Top contributing authors, organizations, countries and research field were identified with the Web of Science built-in results analysis tool. Additionally, keyword mapping was performed with VOSviewer software. The analysis of the network and overlay keyword maps revealed six clusters: healthcare, technology adoption, management, information security, technical solutions and physical security. The results of this study suggest attractive research directions to be pursued in the future, such as information security training in healthcare and individualized user training alternatives to one-size-fits-all user training approach.
Evaluating Case Study and Action Research Reports: Real-world Research in Cybersecurity
Authors: Vrhovec Simon , Fujs Damjan , Jelovčan Luka , Mihelič Anže
Published: September 2021

There is a growing number of scientific papers reporting on case studies and action research published each year. Consequently, evaluating the quality of pilling up research reports is becoming increasingly challenging. Several approaches for evaluation of quality of the scientific outputs exist however they appear to be fairly time-consuming and/or adapted for other research designs. In this paper, we propose a reasonably light-weight structure-based approach for evaluating case study and action research reports (SAE-CSAR) based on eight key parts of a real-world research report: research question, case description, data collection, data analysis, ethical considerations, results, discussion and limitations. To evaluate the feasibility of the proposed approach, we conducted a systematic literature survey of papers reporting on real-world cybersecurity research. A total of N = 102 research papers were evaluated. Results suggest that SAE-CSAR is useful and relatively efficient, and may offer a thought-provoking insight into the studied field. Although there is a positive trend for the inclusion of data collection, data analysis and research questions in papers, there is still room for improvement suggesting that the field of real-world cybersecurity research did not mature yet. The presence of a discussion in a paper appears to affect most its citation count. However, it seems that it is not uniformly accepted what a discussion should include. This paper explores this and other issues related to paper structure and provides guidance on how to improve the quality of research reports.

Published: September 2021

One in every six persons in the UK suffers a hearing loss, either as a condition they have been born with, or they developed during their life. Nine hundred thousand people in the UK are severely or profoundly deaf. Based on a study by Action on Hearing Loss UK in 2013 only 17 percent of this population, can use the British Sign Language (BSL). That leaves a massive proportion of people with a hearing impediment who do not use sign language struggling in social interaction and suffering from emotional distress. It also leaves even a larger proportion of Hearing people who cannot communicate with those of the deaf community. This paper presents a Serious Game (SG) that aims to close the communication gap between able hearing people and people with hearing impairment by providing a tool that facilitates BSL learning targeting the adult population. The paper presents the theoretical framework supporting adult learning based on which a SG game using Virtual Reality (VR) technology has been developed. The paper explains the experimental framework of the study. It presents the creation of the research instruments to facilitate the study comprising of a SG that integrates video and conventional video-based educational material. It reports and analyses the study results that demonstrate the advantage of the SG in effectively supporting users learning a set of BSL signs. It also presents qualitative outcomes that inform the further development of the game to serve learning needs. The paper closes with conclusions, directions for further development of this educational resource, and future studies.
On the Complexity of Some Variations of Sorting by Transpositions
Authors: Alexandrino Alexsandro , Oliveira Andre , Dias Ulisses , Dias Zanoni
Published: September 2021

One of the main challenges in Computational Biology is to find the evolutionary distance between two organisms. In the field of comparative genomics, one way to estimate such distance is to find a minimum cost sequence of rearrangements (large scale mutations) needed to transform one genome into another, which is called the rearrangement distance. In the past decades, these problems were studied considering many types of rearrangements (such as reversals, transpositions, transreversals, and revrevs) and considering the same weight for all rearrangements, or different weights depending on the types of rearrangements. The complexity of the problems involving reversals, transpositions, and both rearrangements is known, even though the hardness proof for the problem combining reversals and transpositions was recently given. In this paper, we enhance the knowledge for these problems by proving that models involving transpositions alongside reversals, transreversals, and revrevs are NP-hard, considering weights w1 for reversals and w2 for the other rearrangements such that w2/w1 ≤ 1.5. In addition, we address a cost function related to the number of fragmentations caused by a rearrangement, proving that the problem of finding a minimum cost sorting sequence, considering the fragmentation cost function with some restrictions, is NP-hard for transpositions and the combination of reversals and transpositions.
Model Driven Software Engineering Meta-Workbenches: An XTools Approach
Authors: Clark Tony , Gulden Jens
Published: September 2021

Model Driven Software Engineering aims to provide a quality assured process for designing and generating software. Modelling frameworks that offer technologies for domain specific language and associated tool construction are called language workbenches. Since modelling is itself a domain, there are benefits to applying a workbenchbased approach to the construction of modelling languages and tools. Such a framework is a meta-modelling tool and those that can generate themselves are reflective metatools. This article reviews the current state of the art for modelling tools and proposes a set of reflective meta-modelling tool requirements. The XTools framework has been designed as a reflective meta-tool and is used as a benchmark.

Published: September 2021

Technological development and market expansion offer an increased availability of resources and computing power on IoT nodes at affordable cost. The edge computing paradigm allows keeping locally on the edge of the network a part of computing, while keeping all advantages of the cloud and adding support for privacy, real-time and network resilience. This can be further improved in IoT applications by exibly harvesting resources on IoT nodes, by moving part of the computing tasks related to data from the edge server to the nodes, raising the abstraction level of the data aspects of the architecture and potentially enabling larger IoT networks to be efficiently deployed and managed, in a stand-alone logic or as a component of edge architecture. Anyway, an e_cient energy management mechanism is needed for battery powered IoT networks, the most exible implementations, that dynamically balances task allocation and execution in order to In this paper we present a fuzzy logic based power management strategy for IoT subsystem that aims at maximizing the duration of the network by locally migrating part of the computing tasks between nodes. As our goal is to enable the deployment of semi-autonomic large IoT networks, our proposal does not rely on external resources for migration control and operates on a local basis to ensure scalability: at the best of our knowledge, this differentiates our proposal with respect to similar solutions available in literature.

Published: September 2021

The paper presents an innovative OFNBee optimization method based on combining the swarm intelligence with the use of directed fuzzy numers OFN. In the introduction, the issues related to the subject of the study, including bee algorithms and OFN numbers, were reviewed. The innovative OFNBee algorithm was presented and verified against a set of known benchmarks functions such as Sphere, Rastrigin, Griewank, Rosenbrock, Schwefel and Ackley. These functions have been applied due to their reliability in the literature.

Authors: Liu Qun , Huang Gui-Yun , Zhang Dai-Gui , Zhang Jian-Wen , Deng Tao , Li Zhi-Min
Published: September 2021

Youngia hangii T.Deng, D.G.Zhang, Qun Liu & Z.M.Li, sp. nov., a new species of Asteraceae, is described and illustrated. It was collected in Wufeng County, Hubei Province, Eastern Central China. Youngia hangii is morphologically most similar to Y. rubida, but can be easily distinguished from the latter by capitula with 8–10 florets and the hairy leaf surface. Phylogenetic analyses, based on the internal transcribed spacers (ITS) and one chloroplast marker (rps16), showed that Y. hangii and Y. rubida were sister species with good support. The results of both phylogenetic analysis and the morphological data support the specific rank of Y. hangii.
De l’utopie écrite à l’utopie pratiquée. Une réévaluation de la contribution des communautés icariennes de l’Iowa
Authors: Rousselière Damien
Published: September 2021

L’évaluation du succès des communautés utopiques est une question importante mais souvent réduite à celle de la longévité. En nous appuyant sur les travaux de Donald E. Pitzer, et à partir de l’accès à des archives inédites, nous proposons dans cet article de réévaluer la contribution des communautés icariennes de l’Iowa (Corning) qui ont fonctionné dans la seconde moitié du XIX e  siècle. Cette contribution est analysée à partir de trois dimensions : la flexibilité des règles organisationnelles ; l’innovation en matière d’activité économique ; les trajectoires individuelles revues à partir du débat ouverture/fermeture qui est central dans l’analyse de ces communautés, pouvant être vues comme des alternatives utopiques s’assimilant à terme dans la société américaine.
Servir la nation, défendre ses intérêts. Les étudiants français face aux réformes du service militaire (1889-1913)
Authors: Dubois Antonin
Published: September 2021

Face au manque de matériau permettant d’établir précisément le profil social des étudiants français avant la Première Guerre mondiale, il faut, pour comprendre les modalités de leur constitution en un groupe social, retracer le processus réussi de leur organisation collective et sa reconnaissance par les pouvoirs publics. C’est la démarche suivie par cet article, qui montre ce que révèlent de l’émergence et de la structuration du groupe social étudiant en France les trois lois de conscription de 1889, 1905 et 1913, et les mobilisations qu’elles ont suscitées, pour l’introduction de dispositions particulières concernant les étudiants ou en réaction à celles-ci. D’un côté, les campagnes étudiantes autour du service militaire constituent des moments de cristallisation exceptionnels, qui permettent de saisir le rapport de force entre étudiants et pouvoirs publics et ainsi d’interroger le rapport des étudiants à l’État et à la nation. De l’autre, elles reflètent les principales évolutions des formes de mobilisation collective des étudiants durant cette période.
Des « pédantes » et des « glorieuses » : les cours ménagers municipaux et l’encadrement des prétentions populaires (Paris, 1880-1900)
Authors: Depecker Thomas
Published: September 2021

Cet article étudie la manière dont l’ouverture aux jeunes filles populaires de la scolarité post-obligatoire est gérée, lue et encadrée dans la municipalité parisienne à la fin du XIX e  siècle. Alors que les nouveaux cours complémentaires connaissent un succès fulgurant et permettent aux filles issues des classes populaires de préparer des concours scolaires ou leur entrée dans le marché du travail, et suscitent de ce fait de nombreuses critiques, des réformateurs et administrateurs proposent d’y renforcer l’enseignement ménager. Mais il ne s’agit ni de renvoyer ces filles à leur foyer, ni de leur fournir des compétences techniques. Le traitement d’une enquête originale sur la trajectoire sociale des élèves des cours complémentaires permet d’interroger à nouveaux frais les discours concernant la nécessité de l’enseignement ménager dans les curricula féminins. Ils procéderaient, dans ce cas, à l’euphémisation de l’encadrement des aspirations populaires, tout en fournissant un gage moral aux jeunes filles les plus susceptibles de réaliser une ascension sociale à l’aide des nouvelles possibilités offertes par l’école publique.
Gérer la résilience en contexte extrême : le cas de la brigade de sapeurs-pompiers de Paris
Authors: Dietrich Anne , Riberot Jérôme
Published: September 2021

Cet article rend compte des mécanismes de la résilience à l’œuvre au sein d’une organisation militaire chargée de la protection des biens et des personnes de l’agglomération parisienne, la brigade de sapeurs-pompiers de Paris (BSPP). À travers cet article, nous mettons en lumière les ressorts de la résilience organisationnelle montrant leur complémentarité dans leurs aspects organisationnel, structurel et cognitif. Ces ressorts sont illustrés avec trois exemples que sont une situation d’incendie, la séquence des attentats de 2015, et le retour d’expérience à la BSPP.
Humour et résilience en période de crise. Plus de rire pour plus de succès ?
Authors: Hofaidhllaoui Mahrane
Published: September 2021

Cet article vise à exposer les différentes facettes de l’usage de l’humour comme mécanisme de résilience. Malgré ces risques, faire de l’humour, faire rire, soulage grandement les tensions qui existent inévitablement en entreprise, avec les autres ou face à soi-même en période d’incertitude. Pratiquer l’humour est une façon de prendre de la distance avec un problème, c’est aussi le moyen de tisser du lien social, de renforcer la relation avec des collègues et des clients. L’humour est un levier de performance… Cette recherche nous permet d’identifier ce qu’est l’humour, ce qu’il représente au travers de quatre principaux types. Ces types orientent ensuite notre recherche sur les effets positifs ou négatifs que l’humour peut créer ou souligner, dans un environnement managérial. Oser l’humour serait donc une recette efficace pour créer du lien avec ses collaborateurs, et instaurer des échanges plus fluides et productifs entre eux en cette période de crise.

Relation-theoretic metrical coincidence theorems under weak C-contractions and K-contractions
Authors: Sk Faruk ,   Department of Mathematics, Aligarh Muslim University, Aligarh 202002, India, Hossain Asik , Khan Qamrul Haq
Published: September 2021

In this paper, we prove some coincidence point theorems for weak C-contractions and K-contractions involving a new auxiliary function in a metric space endowed with a locally $ f $-transitive binary relation. In this context, we generalize some relevant fixed point results in the literature. Further, we give an example to substantiate the utility of our results.
Identity and narrative ownership in "Black Nerd" and "Wicket: A Parody Musical"
Authors: Storey Scout Kristofer
Published: September 2021

While theatre and popular media alike tend to almost exclusively favor the white, heteronormative, male perspective, much of fandom culture has developed around geek fans' ability to read alternative, and often resistant, meanings into established texts, then transform them into performances that strive to correct the flaws and fill the gaps in the source text. Analysis of Dad's Garage Theatre Company's productions of Jon Carr's Black Nerd (2018) and Travis Sharp and Haddon Kime's Wicket: A Parody Musical (2017) as case studies reveals that geek theatre uses fandom techniques of resistant reading, rewriting, and performance to disrupt and restructure hegemonic narratives to foreground the experiences and perspectives of minorities whose stories frequently fall through the gaps of the established canon.
