Dynamic resource allocations in virtual networks through a knapsack problem's dynamic programming solution
Authors: Kengne Tchendji Vianney , YANKAM Yannick Florian 
Published: January 2021

The high-value Internet services that have been significantly enhanced with the integration of network virtualization and Software Defined Networking (SDN) technology are increasingly attracting the attention of end-users and major computer network companies (Google, Amazon, Yahoo, Cisco, ...). In order to cope with this high demand, network resource providers (bandwidth, storage space, throughput, etc.) must implement the right models to understand and hold the users' needs while maximizing profits reaped or the number of satisfied requests into the virtual networks. This need is even more urgent that users' requests can be linked, thereby imposing to the InP some constraints concerning the mutual satisfaction of requests, which further complicates the problem. From this perspective, we show that the problem of resource allocation to users based on their requests is a knapsack problem and can therefore be solved efficiently by using the best dynamic programming solutions for the knapsack problem. Our contribution takes the dynamic resources allocation as a multiple knapsack's problem instances on variable value requests.
La multitude des services à forte valeur ajoutée offert par Internet et améliorés considérablement avec l'intégration de la virtualisation réseau et de la technologie des réseaux définis par logiciels (Software Defined Networking), suscite de plus en plus l'attention des utilisateurs finaux et des grands acteurs des réseaux informatiques (Google, Amazon, Yahoo, Cisco, ...); ainsi, pour faire face à cette forte demande, les fournisseurs de ressources réseau (bande passante, espace de stockage, débit, ...) doivent mettre en place les bons modèles permettant de bien prendre en main les besoins des utilisateurs tout en maximisant les profits engrangés ou le nombre de requêtes satis-faites dans les réseaux virtuels. Ce besoin est d'autant plus urgent que les requêtes des utilisateurs peuvent être interdépendantes, imposant de ce fait au FIP des contraintes de satisfaction mutuelle des requêtes, ce qui complexifie encore plus le problème. Dans cette optique, nous montrons que le problème d'allocation des ressources aux utilisateurs en fonction de leurs requêtes, se ramène à un problème de sac à dos et peut par conséquent être résolu de façon efficiente en exploitant les meilleures solutions de programmation dynamique pour le problème de sac à dos. Notre contribution considère l'allocation dynamique des ressources comme une application de plusieurs instances du problème de sac à dos sur des requêtes à valeurs variables.
ε-TPN: definition of a Time Petri Net formalism simulating the behaviour of the timed grafcets
Authors: Sogbohossou Médésu , Sogbohossou Medesu , Vianou Antoine , Gmati Nabil , Badouel Eric , Watson Bruce 
Published: January 2021

To allow a formal verification of timed GRAFCET models, many authors proposed to translate them into formal and well-reputed languages such as timed automata or Time Petri nets (TPN). Thus, the work presented in [Sogbohossou, Vianou, Formal modeling of grafcets with Time Petri nets, IEEE Transactions on Control Systems Technology, 23(5)(2015)] concerns the TPN formalism: the resulting TPN of the translation, called here ε-TPN, integrates some infinitesimal delays (ε) to simulate the synchronous semantics of the grafcet. The first goal of this paper is to specify a formal operational semantics for an ε-TPN to amend the previous one: especially, priority is introduced here between two defined categories of the ε-TPN transitions, in order to respect strictly the synchronous hypothesis. The second goal is to provide how to build the finite state space abstraction resulting from the new definitions.
Afin de permettre la vérification formelle des grafcets temporisés, plusieurs auteurs ont proposé de les traduire dans des langages formels de réputation tels que les automates temporisés et les réseaux de Petri temporels (TPN). Ainsi, les travaux présentés dans [Sogbohossou, Vianou, Formal modeling of grafcets with Time Petri nets, IEEE Transactions on Control Systems Technology, 23(5)(2015)] concernent le formalisme des TPN: le réseau résultant de la traduction, dénommé ici ε-TPN, intègre des délais infinitésimaux (ε) pour simuler la sémantique synchrone du grafcet. Le premier objectif de cet article est de définir la sémantique opérationnelle d'un ε-TPN afin d'améliorer l'ancienne définition: spécifiquement, une priorité est introduite ici entre deux catégories de transitions définies pour ces réseaux, dans l'optique de respecter rigoureusement l'hypothèse synchrone. Le second but est de fournir une méthode de calcul de l'espace d'état fini qui découle des nouvelles définitions.

Authors: Fekih-Salem Radhouane , Sari Tewfik 
Published: January 2021

The objective of this study is to analyze a model of the chemostat involving the attachment and detachment dynamics of planktonic and aggregated biomass in the presence of a single resource. Considering the mortality of species, we give a complete analysis for the existence and local stability of all steady states for general monotonic growth rates. The model exhibits a rich set of behaviors with a multiplicity of coexistence steady states, bi-stability, and occurrence of stable limit cycles. Moreover, we determine the operating diagram which depicts the asymptotic behavior of the system with respect to control parameters. It shows the emergence of a bi-stability region through a saddle-node bifurcation and the occurrence of coexistence region through a transcritical bifurcation. Finally, we illustrate the importance of the mortality on the destabilization of the microbial ecosystem by promoting the washout of species.
L'objectif de cette étude est d'analyser un modèle du chémostat impliquant la dynamique d'attachement et de détachement de la biomasse planctonique et agrégée en présence d'une seule ressource. En considérant la mortalité des espèces, nous donnons une analyse complète de l'existence et de la stabilité locale de tous les équilibres pour des taux de croissance monotones. Le modèle pré-sente un ensemble riche de comportements avec multiplicité d'équilibres de coexistence, bi-stabilité et apparition des cycles limites stables. De plus, nous déterminons le diagramme opératoire qui dé-crit le comportement asymptotique du système par rapport aux paramètres de contrôle. Il montre l'émergence d'une région de bi-stabilité via une bifurcation noeud col et l'occurrence d'une région de coexistence via une bifurcation transcritique. Enfin, nous illustrons l'importance de la mortalité sur la déstabilisation de l'écosystème microbien en favorisant le lessivage des espèces.
Malunited Isolated Intra-articular Fracture of Ulnar Head
Authors: Sengodan Mugundhan M 
Published: January 2021

ABSTRACT
Fractures of distal ulna are often associated with fracture distal radius. Isolated intra-articular fractures of ulnar head have very rarely been reported in the literature. Displaced intra-articular fractures of ulna head should be treated properly so that the distal radio ulnar joint congruence is maintained. I am reporting a case of malunited isolated intra-articular fracture of ulnar head in young girl which was treated by open reduction and internal fixation. Logan and Lindau in their review of literature and recommendations for treatment of distal ulna fractures in adults found only few case reports. All those reported cases were treated soon after the injury. This case has been presented not only for its rarity but also to recognize the importance of managing the intra-articular fractures properly even in distal ulna.

Published: January 2021

ABSTRACT

Background and objective
Patient-reported outcome measures continue to play an important role in assessing the performance and determining the comparative effectiveness of total knee arthroplasty. Patient's satisfaction can be influenced by many factors, such as, residual pain, postoperative functionality, and the presence of postoperative complications and hence we evaluated clinical and functional outcomes following total knee arthroplasty. This study was conducted to bust the myth of postoperative pain and disability following a total knee replacement.

Materials and methods
A prospective observational cohort study was conducted among the patients who underwent primary total knee arthroplasty in the Department of Orthopaedics in the Sundaram Medical Foundation during the study period of March 2017 and January 2018. A total of 30 cases were included. During their follow-up, patient's outcomes were assessed using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and American Knee Society Scores (AKSS). Data were analyzed using SPSS v.17.

Results
At the end of 6 months, 76.7% of participants were satisfied with their outcome. Significant improvement was noted in both clinical (p = 0.000) and functional outcome (p = 0.000) of AKSS and total WOMAC scores (p = 0.007) during the follow-up at the sixth month. Also, there was a significant difference in AKSS scores noted with respect to age but other parameters like duration of illness and type of arthritis were not significant.

Conclusion
The majority of study subjects were satisfied with the clinical and functional outcome based on WOMAC and AKSS, which in turn encouraged them to undergo total knee replacement of the other knee.

Clinical significance
From our study, we could determine the importance of patient- and clinician-reported outcome measures in predicting the satisfaction of the patient following total knee replacement. Assessment of a patient planned for total knee replacement, with the outcome scores both preoperatively and postoperatively will give us a brief idea on how better the patient will fair following surgery and will also help us in the rehabilitation of the patient accordingly.

Command Attention Rather Than Demand Concentration
Authors: Winston Joe 
Published: January 2021

Abstract
In this review of Matthew DeCoursey’s book on the aesthetics of drama education, I acknowledge the originality and usefulness of the theoretical framework he provides and attempt to summarize its key features. In applying them to an example of my own practice, I make use of the conceptual terminology DeCoursey has introduced and argue that it is both effective and illuminating to the practitioner. In tracing the trajectory of DeCoursey’s subsequent analysis of key theorists in the field, the study of scripted drama, and the extensive use of drama across the curriculum, I attempt to do justice to the strengths of his argument, as well as pointing out what I perceive as some of its inherent weaknesses. I conclude by indicating some gaps in his attention to both historical and current practices in the field while still commending the book for its much-needed contribution.
Ebola na Folha de São Paulo (1976-2015): invisibilidade e desvalorização cultural da África
Authors: Danfá Lassana , Aléssio Renata Lira dos Santos , Torres Ana Raquel Rosas 
Published: January 2021

Este artigo investigou a construção social da/o ebola via imprensa brasileira à luz da Teoria das Representações Sociais. Os dados foram coletados na Folha de São Paulo, desde o surgimento do vírus (1976) até março de 2015. Foram analisadas 291 matérias, por meio do software IRAMUTEQ. Os resultados mostram mundos léxicos organizados em torno dos discursos especialista e não especialista. O primeiro traduz as hipóteses científicas explicativas sobre o vírus do ebola. Já segundo aponta para a dicotomia ocidente versus África. Os resultados demonstram que a crise da ebola reatualiza a themata do reconhecimento social pela negativa, o essencialismo do africano, alteridade radical, hierarquização cultural e a invisibilidade do africano como protagonista apto a falar de sua realidade.
Fichte e a estrutura da magia
Authors: Ferraguto Federico 
Published: January 2021

Objetivo deste artigo é discutir a recepção fichteana do mesmerismo e avaliar criticamente a interpretação fichteana do rapport como instrumento para desenvolver uma reflexão em torno das condições de possiblidade para a elevação ao ponto de vista transcendental. A minha tese é que Fichte opera uma assimilação seletiva do magnetismo animal, mas recusa os seus elementos fundamentais. Em especial Fichte explora a possibilidade de entender a Wisseschaftslehre como uma abordagem filosófica que pretende superar os limites que definem a concretude do sujeito. Porém, em reestruturar e repensar a abordagem do magnetismo animal como forma de interação linguística, ele se aproxima as modernas concepções da magia como pontenciamento da liberdade e da performance humana.Para demonstrar esta tese irei fornecer uma problematização da estrutura da magia entre época moderna e contemporânea a partir do problema da comunicação (§ 1); situar neste contexto a reflexão fichteana sobre a estrutura da doutrina da ciência como saber incomunicável (§ 2); problematizar a recepção fichteana do mesmerismo no Diário sobre o magnetismo animal de 1813 (§ 3); aplicar os resultados desta problematização na leitura da reflexão fichteana acerca da relação entre percepção e atenção nas lições sobre os Tatsachen des Bewusstseins de 1811 (§ 5).
The two souls of Schopenhauerism: analysis of new historiographical categories
Authors: Miglietta Giulia 
Published: January 2021

The Wirkungsgeschichte of Schopenhauerism is a complex mixture of events, encounters, influences and transformations. In order to orient oneself concerning such an articulated phenomenon, it is necessary to have valid hermeneutical tools at hand. In this contribution, I am going to propose a reading of the history of the effects of Schopenhauerism through new and effective historiographical categories that resulted from the research conducted by the Interdepartmental Research Centre on Arthur Schopenhauer and his School at the University of Salento. On the one hand, I will refer to Domenico Fazio’s studies on the Schopenhauer-Schuleand, on the other, to Fabio Ciracì’s research on the reception of Schopenhauer’s philosophy in Italy. This approach will reveal how the formulation of the so-called “two souls” of Schopenhauerism, the romantic and the illuministic, allows us to unravel the multifaceted panorama of the history of the effects of Schopenhauerian philosophy, in line with the subdivision within the Schopenhauer-Schule of metaphysical and heretical thinkers.

Posttraumatic stress disorder in childhood and adolescence: Issues on diagnosis and assessment Abstract: The aim of the study was to compare DSM-IV, DSM-5 and alternative criteria for PTSD, in three independent samples, with the purpose of analyzing their suitability. The sample consisted of 361 minors with ages between 8 and 18 years, (122 community sample, 86 minors that suffered chronic family violence and 153 minors exposed to intimate partner violence). From the entire sample, 52.9% (n = 191) were girls and 47.1% (n = 170) were boys. The CPPS (Child PTSD Symptom Scale) was administered. The results showed a better PTSD diagnostic valuation using alternative criteria for the different ages and sample groups. An exhaustive revision of current PTSD diagnostic criteria for childhood and adolescence stages seem necessary.Keywords: Evaluation; diagnosis; PTSD; childhood; adolescence. Resumen: El estudio tuvo por objetivo comparar criterios DSM-IV, DSM-5 y criterios alternativos de TEPT, en tres muestras independientes con la finalidad de analizar la idoneidad de estos. La muestra se configuró con 361 menores entre los 8 y 18 años (122 muestra comunitaria; 86 menores habían sufrido maltrato intrafamiliar crónico y 153 menores expuestos a violencia de género). De la totalidad de la muestra el 52.9% (n = 191) eran chicas y el 47.1% (n = 170) chicos. Se administró la escala CPSS (Child PTSD Symptom Scale). Los resultados evidenciaron una mejor valoración diagnóstica del TEPT utilizando los criterios alternativos en las diferentes edades y en los diferentes grupos muestrales. Parece necesario una revisión exhaustiva de los criterios diagnósticos TEPT actuales en la etapa de la infancia y la adolescencia.

Diversas investigaciones destacan la importancia de la motiva-ción en el rendimiento cognitivo y también la importancia de la motivación en la metacognición. El objetivo de esta investigación es indagar en las va-riables motivacionales que influyen en el rendimiento de tareas cognitivas y en la metacognición. La investigación se ha realizado en un colegio público de la Comunidad de Madrid. La muestra de este estudio corresponde a 354 alumnos de educación primaria, entre los 8 y 11 años de edad. Los instru-mentos de medida seleccionados son: el cuestionario de Motivación hacia el Aprendizaje (MAPE-I), para las variables motivacionales; el Junior Meta-cognitive Awareness Inventory (Jr. MAI), para las variables metacognitivas y la batería de pruebas de Evaluación Neuropsicológica de las Funciones Ejecutivas en Niños (ENFEN), para la evaluación del rendimiento cogniti-vo. Los resultados obtenidos muestran efecto de la motivación de orienta-ción al aprendizaje en relación con el rendimiento cognitivo en las pruebas que implican inhibición, flexibilidad y memoria operativa. También se ob-serva efecto significativo entre la disposición al esfuerzo y la regulación del conocimiento. Igualmente, se analizan las relaciones entre las variables por curso para determinar el efecto de la edad. Se valoran las implicaciones educativas de los resultados.
Sundry studies have emphasised the importance of motivation in cognitive performance, as well as its link to metacognitive development. The objective here is to explore the motivation variables that influence the performance of cognitive tasks, along with their effect on metacognition. The study sample consists of 354 primary school pupils aged 8-11 at a state school in the Community of Madrid (Spain). The following measuring in-struments have been used for studying the variables: Motivación para el Aprendizaje y la Ejecución (MAPE-I) [Motivation for Learning and Execu-tion], a questionnaire on motivation variables; the Junior Metacognitive Awareness Inventory (Jr. MAI), for metacognitive variables, and the bat-tery of tests in the Evaluación Neuropsicológica de las Funciones Ejecutivas en Ni-ños (ENFEN) [Neuropsychological Assessment of Executive Functions in Children], for assessing cognitive performance. The results reveal a signifi-cant effect between the motivation for focusing on learning and cognitive performance in the tasks that involve inhibition, flexibility, and working memory. We also find a significant effect between increased effort and knowledge regulation. Furthermore, we analyse the relations between the variables by school year to determine the age effect. We evaluate the re-sults’ academic implications.

Authors: Miranda Jenniffer K. , Rojas Carolina , Crockett Marcelo A. , Azócar Estrella 
Published: January 2021

Crecer en el contexto de violencia de género en la pareja (VGP) se ha relacionado con problemas de salud mental en los/as hijos/as, sin embargo, poco se conoce sobre los efectos de la VGP desde el punto de vista de los propios hijos/as. El objetivo de esta investigación fue comprender el impacto psicológico asociado a vivir en contexto de VGP desde la perspectiva de los/as niños/as. Se realizaron entrevistas semiestructuradas con 3 niños y 5 niñas entre 8 y 12 años, que asistían a Programas de Protección Infanto-Juvenil y que habían crecido con diferentes formas de VGP crónica en el hogar. Las entrevistas se analizaron mediante análisis narrativo. Los resultados muestran que crecer en un contexto de VGP posee un impacto psicológico en los/as niños/as, principalmente en su bienestar emocional, las relaciones familiares y, en algunos casos, en las descripciones de sí mismos/as. Se concluye que las experiencias de VGP pueden tener un impacto significativo en la vida de los/as niños/as y afectar diferentes ámbitos de sus vidas. Los hallazgos enfatizan la importancia de comprender los efectos de la VGP desde la perspectiva de los/as hijos/as, con el fin de desarrollar intervenciones clínicas de acuerdo con sus necesidades.
Growing up in the context of gender-based intimate partner violence (IPV) has been associated with mental health problems in children yet little is known about IPV effects on children from their own point of view. The aim of this research was to understand the psychological impact associated with living in an environment with IPV, from the perspective of children. Semi-structured interviews were conducted with 3 boys and 5 girls, between 8 and 12 years old, who were attending psychosocial programs specialized in maltreatment and experimented different forms of chronic IPV at home. The interviews were analyzed using narrative analysis. The results show that growing up in an environment with IPV has a psychological impact on children’s emotional wellbeing and family relationships, and in some cases on their self-concept. We conclude that IPV experiences had a profound impact on the participants’ wellbeing, affecting various areas of the children’s lives. The results highlight the importance of understanding the effects of IPV from the children’s perspective, in order to develop clinical interventions in accordance with their needs.
Profil spatial des infractions sexuelles à Austin, au Texas
Authors: Hewitt1 Ashley N. , Dubois Florence 
Published: January 2021

Les études portant sur les crimes et les lieux ont toujours insisté sur l’importance de comprendre le profil spatial des crimes à l’aide d’unités d’analyse de plus en plus réduites. Même si de nombreuses études ont adopté cette perspective, peu se sont intéressées spécifiquement aux crimes à caractère sexuel. La présente étude se sert des données d’incidents enregistrés par la police pour étudier la distribution spatiale des infractions sexuelles ayant eu lieu entre le 1erjanvier 2016 et le 31 décembre 2018 à Austin, au Texas (N = 1381). Les infractions ont d’abord été divisées selon l’âge des victimes (enfant ou adulte) et le type d’acte sexuel perpétré (infraction sexuelle avec pénétration, avec contact et sans contact), ensuite trois mesures de concentration spatiale, des analyses de noyaux de densité et des analyses de dispersion spatiale ont été réalisées. Les résultats montrent que les infractions sexuelles commises contre des enfants et des adultes étaient concentrées dans l’espace, mais que leur degré de concentration dépendait du type d’acte commis. De plus, les analyses de dispersion spatiale semblent montrer que les segments de rue (et les intersections) où ont lieu de telles infractions diffèrent en fonction de la nature de l’acte sexuel perpétré. Les implications pour la prévention situationnelle et le maintien de l’ordre (policing) seront discutées.
