Les logiques des systèmes de retraite en Europe
Authors: ApRoberts Lucy
Published: March 2021

Les comparaisons internationales en sciences sociales sont construites afin de répondre à une question particulière ou pour étayer une certaine analyse. De nouvelles questions ou analyses, et donc de nouveaux cadres de comparaison, peuvent émerger selon l’évolution des institutions. Cet article examine tout d’abord deux typologies couramment utilisées pour caractériser les différents systèmes de retraite nationaux. La première oppose systèmes bismarckiens et beveridgiens. Elle se centre sur les seuls régimes de base et laisse dans l’ombre les dispositifs instaurés par des acteurs sociaux autres que l’État. Le schéma des trois «piliers», promu d’abord en Suisse et repris par la Banque mondiale et la Commission européenne, est ensuite exposé. Il a l’avantage de prendre en compte toutes les catégories de dispositifs de retraite, mais il est généralement appliqué de façon normative, afin de promouvoir la capitalisation et contenir la répartition. L’auteur aborde enfin deux questions concernant des enjeux majeurs actuels: celle du périmètre de la solidarité mise en place par les systèmes de retraite et celle des garanties offertes aux participants par les régimes en répartition. Une réflexion à partir de ces questions pourrait contribuer à repenser les concepts habituellement utilisés dans les comparaisons internationales des systèmes de retraite.

Les seniors, définis ici comme étant les personnes qui ont au moins 60 ans, sont plus fréquemment membres d’associations que leurs cadets. Cette situation trouve une partie de son explication dans l’incitation à l’adhésion que constitue le départ en retraite. Cet engouement bénéficie essentiellement aux associations qui sont spécifiquement tournées vers les personnes âgées. Dans la majorité des cas, cette participation prend la forme d’une consommation de services et d’une pratique d’activités récréatives. Elle se traduit moins souvent par une implication dans le fonctionnement des associations et a fortiori par l’exercice de responsabilités. Les seniors restent néanmoins des pourvoyeurs importants de ressources humaines bénévoles notamment dans le domaine de l’action sociale et caritative. C’est particulièrement le cas des sexagénaires qui, lorsqu’ils rendent des services non rémunérés dans le cadre de leurs associations, consacrent en moyenne à ces activités plus de temps que leurs homologues moins âgés. Qu’ils se contentent, en tant qu’adhérents, d’être usagers des prestations offertes par les organisations dont ils sont membres ou qu’ils soient au contraire plus engagés comme bénévoles, le comportement associatif des seniors paraît tout particulièrement stimulé par la recherche de rencontres avec autrui et la volonté de nouer des amitiés. L’importance de ces motivations relationnelles souligne le rôle de réseau de sociabilité qu’assure le tissu associatif pour cette partie de la population.
Un éclairage du droit québécois
Authors: Burke Tanaquil
Published: March 2021

Au Québec, trois lois garantissent le droit à l’égalité et le principe de non-discrimination dans l’emploi. Il s’agit de la Charte canadienne des droits et libertés, de la Charte des droits et libertés de la personne et de la Loi canadienne sur les droits de la personne. Chacune de ces lois assure une protection contre les atteintes discriminatoires fondées sur l’âge qui peuvent avoir cours tout au long du parcours de vie professionnelle d’un travailleur, quel que soit son âge ou le groupe d’âges auquel il appartient. En comparaison avec les autres motifs de discrimination punis par la loi, l’âge sème une certaine confusion et reçoit, du gouvernement québécois comme des différentes instances juridictionnelles, un traitement distinct. En effet, dès l’accès à l’emploi et jusqu’à la rupture du lien d’emploi, une personne peut faire l’objet d’une différence de traitement fondée sur l’âge. Lorsqu’une distinction fondée sur l’âge dans l’emploi est prouvée, un employeur, et parfois le gouvernement, doit alors apporter une explication raisonnable pour justifier sa décision ou, s’il reconnaît que l’âge l’a influencée, il peut fournir une justification à cette distinction. Trois justifications des différences de traitement fondées sur l’âge peuvent être invoquées: l’exigence professionnelle justifiée, la promotion sociale et l’utilisation non discriminatoire de l’âge dans le domaine des assurances, des rentes, des avantages sociaux et de la retraite.
Du mauvais usage de mauvais chiffres dans le débat sur le vieillissement de la population
Authors: Le Bourg Éric
Published: March 2021

Les questions démographiques ont donné lieu et peuvent encore donner lieu en France à des débats vigoureux, comme en témoigne la «querelle de l’Ined» au début des années 1990, mais aussi à des articles présentant les réalités démographiques de façon tendancieuse ou même fantaisiste. Cet article donne quelques exemples portant sur les questions de la longévité humaine, de la fécondité et de la taille de la population française. Ces mauvais chiffres ont pollué et obscurci le débat social autour de la question du vieillissement de la population. Depuis quelques années, il semble cependant que ces questions démographiques soient abordées par les spécialistes du domaine de façon plus raisonnée. L’auteur, impliqué par le passé dans des critiques à l’égard de l’Ined, fait donc ici le point sur ces questions avec l’espoir que de telles erreurs ne se reproduisent plus.
La santé des travailleurs âgés en Europe
Authors: Sirven Nicolas , Sermet Catherine
Published: March 2021

Cette étude propose de dresser un bilan de l’état de santé des travailleurs âgés entre 50 et 60 ans dans 14 pays européens, à partir des données individuelles de l’enquête Share (2006-2007). L’analyse procède à des comparaisons internationales en s’appuyant sur plusieurs mesures de l’état de santé – objectives et subjectives – , et pour lesquelles l’effet confondant des caractéristiques sociodémographiques est pris en compte. Bien que le recours à plusieurs mesures de santé ne permette pas de dégager un schéma européen bien tranché, deux résultats principaux émergent. D’une part, on constate une importante hétérogénéité des situations entre les pays d’Europe en matière d’état de santé des travailleurs de 50-59 ans. D’autre part, les actifs occupés français comptent parmi les travailleurs de 50-59 ans les plus souvent en mauvaise santé.
L’insomnie et son double littéraire, figure de l’inquiétante étrangeté
Authors: Le Toullec Éric
Published: March 2021

En psychanalyse, la dimension symptomatique de l’insomnie ne peut aller de soi, il s’agit d’en élucider le sens caché et d’interroger sa dimension inconsciente. Car l’insomnie met en échec toute forme d’interprétation immédiate. Alors, de quoi vient-elle nous parler ? L’hypothèse d’une écriture de l’insomnie dans les formations de l’inconscient nous permet d’en aborder la problématique dans les champs conjoints de la clinique et de la littérature. À partir d’une nouvelle d’Alice Munro, extraite de son dernier recueil intitulé Rien que la vie ( Dear Life, 2012 en anglais), nous avons étudié la relation entre l’insomnie d’une adolescente et la question de la castration dans son rapport au père. « Nuit » – c’est le titre de la nouvelle – fait également référence au texte du conte d’E.T.A. Hoffmann, « L’homme au sable » ( Contes nocturnes, 1817), commenté par Freud dans « L’inquiétante étrangeté » (1919), et nous avons donc interrogé le lien de l’insomnie avec la notion freudienne de l’inquiétante étrangeté.
Rêves traumatiques et cauchemars d’exilés
Authors: Baldet Isabelle
Published: March 2021

La difficulté à dormir, voire son impossibilité, la répétition de cauchemars horrifiques et la ténacité de terreurs nocturnes sont souvent les motifs qui conduisent les réfugiés d’un cao (centre d’accueil et d’orientation) à se présenter à « l’accueil-psy », proposé depuis trois années par des psychanalystes bénévoles. Écouter cette plainte et leur proposer de raconter ce qui hante leurs jours et leurs nuits est une façon d’entrer de plein fouet dans des existences que la vie a cruellement malmenées et de mettre à l’épreuve la théorie freudienne du rêve, du traumatisme et de la pulsion de mort.
Sensibilité, conceptualisation et totalité [activité-expérience-corps-monde]
Authors: Récopé Michel , Fache Hélène , Viard Jacques
Published: March 2021

Notre contribution livre les conclusions principales d’un travail d’interprétation des matériaux issus d’une série d’études de terrain dans le champ des pratiques corporelles (ici, le volley-ball). Elles prennent la forme de propositions pour penser les relations activité-expérience-incorporation. Notre éthologie phénoménologique des pratiques humaines ordinaires accorde le primat aux divers types de régularités repérables dans, par et après l’action en situation, et soutient que l’activité et l’expérience, toujours singulières et contingentes, peuvent être approchées utilement par une schématisation/condensation. Les résultats établissent l’existence de différents modes/mondes de pratique, émergeant d’une dialectique complexe et énigmatique entre sensibilité et conceptualisation en acte, valeurs et connaissances pratiques, normes et schèmes. Nous suggérons de porter l’attention sur un processus évolutif aboutissant à une structure [activité-expérience-corps- monde] orientée par un sens structurant.

Formation continue en ligne des enseignants à l’université de Macerata : un parcours entre savoirs théoriques et savoirs pratiques
Authors: Magnoler Patrizia , Rossi Pier Giuseppe , Scagnetti Fabiola
Published: March 2021

Cet article présente un dispositif de formation continuée en ligne pour les enseignants mis en place par l’Université de Macerata (Italie) depuis 2005. Ce programme de formation vise à articuler les savoirs théoriques et pratiques et à développer une démarche réflexive sur l’activité professionnelle. U’objectiffinal est d’amener les enseignants à aller au-delà de l’assimilation et de l’exécution de savoirs théoriques transmis dans le cadre de la formation. Il s’agit de les inciter à adopter la démarche d’un enseignant-chercheur qui identifie un problème vécu en classe, le situe dans son contexte, en analyse les causes possibles, met en place un dispositif destiné à le résoudre, le teste, et l’évalue . Sur la base de l’analyse de différentes traces, les chercheurs ont découvert que les comportements des enseignants engagés dans ce programme de formation variaient considérablement. (lors qu’une majorité d’entre eux se limite à appliquer les savoirs enseignés dans les modules de la formation et à exécuter les tâches confiées par les formateurs, une minorité dépasse cet objectif et s’approprie une démarche de recherche basée sur les principes de la résolution d’une situation- problème. Les auteurs illustrent cette démarche d’appropriation, ils en décrivent les conditions, et émettent des hypothèses explicatives relatives à ces différences de comportements cheq les enseignants face à un même dispositif de formation .
L’analyse de l’activité en sciences de l’éducation : entre aspirations scientifiques et exigences pragmatiques
Authors: Albero Brigitte
Published: March 2021

En clôture de ce numéro, cette contribution a pour but de discuter les positions épistémologiques des articles proposés. Elle contextualise l’approche adoptée dans certains travaux (l’analyse du cours d’action) en relation avec les principales caractéristiques de la discipline (sciences de l’éducation) et avec d’autres approches qui ont en commun l’intérêt pour l’analyse de l’activité. La première partie rapproche l’apport de ces travaux d’une caractéristique structurelle spécifique de la discipline, à savoir l’interrelation étroite entre dimensions épistémique, praxéologique et axiologique, propre à l’acquisition humaine des connaissances. Le postulat invoqué par certains auteurs d’une capacité d’autonomie également distribuée chez tous dans l’acquisition des connaissances est ensuite interrogé. Dans une deuxième partie, les travaux sont situés par rapport à l’intérêt, récent dans la discipline, pour le concept d’ « activité » et la production d’une diversité d’approches qui tendent davantage à coexister qu’à dialoguer. La question se pose alors de l’absence d’intérêt dans nombre d’études pour le rôle et la fonction toujours plus déterminants des objets techniques dans les formes actuelles de l’acquisition des connaissances. La troisième partie rapproche des travaux fondateurs dans le domaine, des cadres théoriques, des concepts et des méthodes susceptibles de constituer un corpus commun aux différentes approches de l’analyse de l’activité, référé aux caractéristiques structurelles de la discipline.

Effect of Keratin Extracted from Chicken Feather Filled Electrospun Polyacrylonitrile Nanocomposite Membrane
Authors: Bayot Jezza B. , Cuartero Alexandra , Aquino Ruth R. , Marquez Menandro C. , Villanueva Joel L. , Tapas Gabriel Angelo
Published: March 2021

Chicken feathers are known for its unique properties such as low density, warmth retention, and distinct morphological structure [1]. Despite these unique properties, chicken feathers are considered a waste byproduct of the poultry industry [2]. To utilize feather waste, it was used as an additive to reinforce Polyacrylonitrile (PAN) polymer in the form of Keratin Extract. The highlight of the study is to prepare and characterize PAN with chicken feather keratin as additive by electrospinning. Keratin was extracted under reduction method with the use of sodium sulphide and solubilized with NaOH [3]. The presence of Keratin was confirmed with Fourier Transform Infrared Microscopy (FTIR) and Ultraviolet–visible Spectroscopy (UV-Vis).PAN nanofibers with different keratin loadings were formed by electrospinning process and Dimethylformamide (DMF) as solvent. The electrospun nanocomposite membranes were analyzed using Scanning Electron Microscopy (SEM), FTIR, contact angle goniometer, and Ion-Adsorption test. Addition of keratin into the polymer solution, decreased the average fiber diameter from 91nm (Pure Keratin), 84nm (PAN/1%Keratin), 71nm (PAN/3%Keratin) to aggregates (PAN/5%Keratin). Also, the change in morphology affected the polymer’s hydrophilicity. As the percentage loading of keratin increases, the average contact angle decreases. The average contact angle of Pure Pan, 1%, 3%, and 5% keratin decreased from 28.21°, 18.85°, 16,76° to 15.34°. The effect of the fiber on conductivity was also tested with a salt bath method. 3M of NaCl solution presented a conductivity of 93.0 mS. Upon the addition of Pure PAN in saltwater Solution, the conductivity had decreased to 60.0mS which indicated that some ions from the NaCl had adhered to the membrane. Upon the addition of Keratin nanofibers, it can be observed that the conductivity increases to 61.0 mS, 96.8 mS. and 100.1 mS as the percentage of keratin loading increases.
Hydroxychloroquine dosing and toxicity
Authors: Al Adel Fadwa , Shoughy Samir S. , Tabbara Khalid F.
Published: March 2021

PURPOSE:

To assess the ocular toxicity in patients on high doses of hydroxychloroquine (HCQ) per weight, as per the latest American Academy of Ophthalmology (AAO) screening guidelines for HCQ toxicity.

METHODS:

This is a multi-center study looking at consecutive patients attending the ophthalmology clinics at a tertiary hospital and a private clinic in Saudi Arabia. A data collection sheet was used to collect patient's information regarding the dose per body weight, duration of HCQ use and any risk factors associated with the use of the medication as per the latest AAO guidelines for HCQ screening. Ancillary testing including fundus photography, automated visual field (10-2) and spectral domain ocular coherence tomography were done. Further testing with fundus auto-fluorescence and multifocal ERG were done when needed. The presence or absence of toxicity was recorded.

RESULTS:

A total of 63 patients were included in the study, 58 females and 5 males. The average patient age was 45 years (range 18–72). The mean dosage of HCQ was 3.9 mg/kg. Fourteen (22%) patients were on doses higher than 5 mg/kg. The duration of treatment ranged from 1-30 years (average 8.3). Thirty six (57%) patients were on the drug for more than 5 years. We found only one (1.58%) patient with HCQ toxic retinopathy over a mean of 8 years treatment period.

CONCLUSION:

A significant number of our patients were found to be on doses of >5 mg/kg of HCQ, which may put them at a higher risk for retinal toxicity. Low dose HCQ such as 100 mg tablets should be made available to help physicians in adjusting the dose as per the latest reported guidelines by the AAO.
Back to the future in traumatic fracture shapes of lumbar spine
Authors: Fusini Federico , Colò Gabriele , Risitano Salvatore , Massè Alessandro , Rossi Laura , Coniglio Angela , Girardo Massimo
Published: March 2021

Introduction:

Nonosteoporotic burst vertebral fracture could commonly be treated with conservative or surgical approach. Currently, decision-making process is based on thoracolumbar (TL) AO spine severity injury score. However, some factors could affect posttraumatic kyphosis (PTK) and could be taken into account. The aim of the present study is to identify if axial and sagittal fracture shape and initial kyphosis are the risk factors for PTK.

Materials and Methods:

All consecutive patients treated between 2016 and 2017 for TL vertebral fracture with conservative treatment were retrospectively evaluated in the study. Only type A3 and A4 vertebral fractures were included in the study. Patients suffering from osteoporosis or other metabolic bone disease, aged above 60 years old were excluded from the study. Initial and 6 months X-ray from injury were analyze to evaluate local kyphosis and region of injury while initial assessment was performed with computed tomography to better identify fracture type and in some cases magnetic resonance imaging to exclude posterior ligament complex injury. Axial and sagittal view of the vertebral plate was analyzed and classified in three shapes according to fragment comminution and dislocation. Statistical analysis was performed trough STATA13 software. Student's t-test was used to evaluate the differences between initial and follow up kyphosis; odds ratio (OR) was used to evaluate the role of initial kyphosis, vertebral sagittal and axial fracture shape as a risk factor for PTK. Kruskal–Wallis test was used to assess the differences among vertebral shape fractures and final kyphosis. Fisher's exact test was used to assess the differences between fracture patterns and final kyphosis.

Results:

An initial kyphosis >10° (OR 36.75 P = 0.015), shape c vertebral plate (OR 147 P = 0.0015), and sagittal shape 3 (OR 32.25 P = 0.0025) are strongly related with PTK. Kruskal–Wallis test revealed a statistically significant difference among axial fracture shape (P < 0.0001) and sagittal fracture shape (P = 0.004) and also for initial kyphosis >10° (P < 0.0001). Fisher's exact test showed a significant difference for final kyphosis among pattern c3 and other patterns of fracture (P = 0.0001).

Conclusions:

A burst type lumbar vertebral fracture affecting a patient with initial local kyphosis >10° and comminution and displacement of vertebral plate and vertebral body is at high risk to develop a local kyphosis >20° in the follow-up if treated conservatively.

Porosity and Permeability Measurements Integration of The Upper Cretaceous in Balad Field, Central Iraq
Authors: Al-Beyati Fawzi
Published: February 2021

The corrected porosity image analysis and log data can be used to build 3D models for porosity and permeability. This can be much realistic porosity obtainable because the core test data is not always available due to high cost which is a challenge for petroleum companies and petrophysists. Thus, this method can be used as an advantage of thin section studies and for opening horizon for more studies in the future to obtain reservoir properties. Seventy-two core samples were selected and the same numbers of thin sections were made from Khasib, Sa`di, and Hartha, formations from Ba-1, Ba-4, and Ba-8 wells, Balad Oilfield in Central Iraq to make a comprehensive view of using porosity image analysis software to determine the porosity. The petrophysical description including porosity image analysis was utilized and both laboratory core test analysis and well log analysis were used to correct and calibrate the results. The main reservoir properties including porosity and permeability were measured based on core samples laboratory analysis. The results of porosity obtained from well log analysis and porosity image analysis method are corrected by using SPSS software; the results revealed good correlation coefficients between 0.684 and 0.872. The porosity range values are 9-16% and 9-27% for Khasib and Sa’di in Ba-1 Well, respectively; 10-21%, 9-25%, and 16-27% for Khasib, Sa’di and Hartha in Ba-4 Well, respectively; and 11-24% and 15-24% for Khasib and Hartha in Ba-8 Well, respectively according to petrographic image analysis. By using the laboratory core analysis, the porosity range values are 12-26% and 17-24% for Khasib and Sa’di in Ba-1 Well, respectively; 6-28% and 14-27% for Sa’di and Hartha in Ba-4 Well, respectively; and 17-19% and 15-24% for Sa’di and Hartha in Ba-8 Well, respectively. Finally, the well log analysis showed that the porosity range values are 11-16% and 7-27% for Khasib and Sa’di in Ba-1 Well, respectively; 4-18%, 21-26%, and 16-19% for Khasib, Sa’di and Hartha in Ba-4 Well, respectively; and 9-24% and 15-23% for Khasib and Hartha in Ba-8 Well, respectively. The permeability range values based on laboratory core analysis are 1.51-8.97 md and 0.29-2.77 md for Khasib and Sa’di in Ba-1 Well, respectively; 0.01-24.5 md and 0.28-6.47 md for Sa’di and Hartha in Ba-4 Well, respectively; and 0.86-2.25 md and 0.23-3.66 for Sa’di and Hartha in Ba-8 Well, respectively.

A Study on the Cross-cultural Communication Strategies of Yue Opera
Authors: Lingling Lou
Published: February 2021

Yue Opera, the second-largest opera in China, is also known as “the most widely spread local opera genre in China”. It is called “Chinese Opera” abroad. The overseas dissemination of Yue Opera has extremely far-reaching significance for displaying traditional Chinese culture, telling Chinese stories well, and building cultural confidence. Based on combing the status quo of overseas communication of Yue Opera in different stages, the paper analyzes the currently existing problems, and then, under the guidance of Lasswell’s Model of Communication, discusses cross-cultural communication strategies of Yue Opera from five aspects, namely “who”, “says what”, “in which channel”, “to whom” and “with what effect”.
No reflective loss: The English approach reconsidered
Authors: Rahmani Ataollah
Published: February 2021

A company shareholder should have no difficulty in commencing a claim to recover the loss suffered due to a wrong done to their personal property. The right to the protection of property is a fundamental human right in English law. A wronged person whose property right is infringed will have the right to commence legal proceedings against wrongdoers. However, in the company context, the exercise of a shareholder’s right of action may conflict with the company’s right of action where the loss sought is reflective. The English company law’s arrangement has been that a shareholder’s action is exceptional beyond which it will routinely be barred through the principle of the ‘no reflective loss’. Where company’s loss and the shareholders’ loss are reflectively linked, then the company’s action prevails against the shareholder action. This paper argues that the two actions should swap places in law. Shareholder action should be recognised as a general principle of law while it is barred exceptionally in circumstances where stronger policy considerations such as the observation of the corporate autonomy are to be prioritised. This article refers to company law in the UK.
The role of Personal Development Planning (PDP) for employer sponsored students - an exploration of how PDP learning activities can support CPD and workforce development requirements
Authors: Savory Julie
Published: March 2021

Over the past decade government policy has emphasised the need for effective and active partnerships between employers and higher education providers (DfES, 2003; Wedgewood, 2007; CBI, 2008; BIS, 2009) to meet the requirements of a globalised knowledge economy. This paper discusses the findings from a research project undertaken at the University of Salford which sought to explore how:Personal Development Planning (PDP) input can support the development of employability skills for part-time sponsored students.Employer engagement could be drawn upon to enhance such provision.Informed by the Appreciative Inquiry approach (Cooperrider 1986, cited Reed, 2007), the methodology included a questionnaire survey of two student cohorts and thirteen semi-structured interviews with organisational development managers from sponsoring organisations to explore perceptions of the value of PDP within day release provision and potential benefits to the organisation. A follow up focus group with employers explored further staff development needs and the potential for PDP processes within Higher Education (HE) courses to complement their existing Continuing Professional Development (CPD) and in-house staff and workforce development strategies.Savory, Conroy and Berwick The role of Personal Development Planning (PDP) for employer sponsored studentsThe paper concludes that dialogue between academic staff, students and sponsoring employers is valuable in developing shared understandings of the role of PDP activities within HE curriculum, the potential benefits for individual professional development and the workforce development requirements of organisations. Employers participating in the research stressed the importance of 'functioning knowledge' (Biggs 2003, cited Walsh, 2008) and discussions highlighted the potential for PDP to provide a bridge between the discipline specific knowledge which forms the main focus of HE courses and the trans-disciplinary knowledge produced by the largely informal learning that occurs during the course of professional practice (Gibbons et al., 1964). The joint dialogue enabled exploration of perceptions of the difference between CPD and PDP and identification of how links between PDP and appraisal processes in the workplace could be strengthened, including suggestions for practical activities which could be incorporated into HE programmes and employers' performance review processes.
Hacking assignment practice: finding creativity and power in the fissures and cracks of learning and teaching
Authors: Abegglen Sandra , Burns Tom , Sinfield Sandra
Published: March 2021

This paper explores integrated peer mentoring in the context of offering students an element of choice in their assignments. We decided to undertake a pilot study with a group of first year undergraduate education-studies students who come from non-traditional backgrounds, but the concept is widely applicable. We argue that creative approaches to assignment practice can promote inclusion and give students, not traditionally welcome in the academy, ownership, voice and pride.
Incorporating augmented reality to enrich student learning
Authors: Bree Ronan T.
Published: March 2021

Learning in higher education is now performed across several dimensions, for example: face-to-face in the classroom or practical sessions; engaging with reusable learning objects; online distance learning and virtual learning environments, all represent significant 'places' of learning. With the advent of technology, the incorporation of multimedia resources to complement lecture theory/practical applications is increasingly evident in modules and programmes. However, with these advances come excessive supplementary digital resources that are available to students, often across multiple platforms. The resources can become separated from relevant lecture notes and this disconnection represents a potential block to learning. Augmented Reality (AR) addresses this concern. Through activation via a 'trigger' image placed in a printed handout, students can engage with specific multimedia content in real-time, and more importantly at the appropriate part of their course. Examples of these multimedia resources are pre-existing online, or customised electronic sketch, videos. Each can be made available for repeat viewings at a later stage, empowering students and benefiting self-paced learning and revision. Here, the role and benefit of AR in empowering students with regard to their learning and the steps needed to introduce AR are discussed.

The impact of Learning Development tutorials on student attainment
Authors: Loddick Alison , Coulson Kate
Published: March 2021

University Learning Development teams provide expert advice to learners regarding the development and enhancement of academic skills such as essay writing, dissertations, critical analysis, mathematics, and statistics. The majority of universities have set up Learning Development or similar academic support services in recent years. However, little research has been conducted to understand the effect of such help on student attainment. At the University of Northampton, this service is perceived as pivotal in supporting students through their studies. The impact on student grades and future attainment was examined using three and a half years of student assessment data (over 16,000 students and 175,000 assessments) which was connected to information gathered from the Learning Development one-to-one tutorials database. Although causality cannot be claimed, there was an average rise of one to two sub grades for learners who attended at least one Learning Development tutorial compared to those who did not use this assistance. Furthermore, historical tutorials positively affected grades of students with an additional two percent increase in their future assignments. Students from the faculties of Business and Law and Education and Humanities saw the largest increase in attainment compared to students within their faculties who did not have tutorials.

This study aims to determine the effect of work discipline and employee performance and the influence of motivation on the relationship between work discipline and employee performance. Work discipline is an attitude that is indispensable for everyone to improve performance in order to achieve organizational goals. Motivation leads to disciplinary attitudes, high motivation for work discipline can affect employee performance. This study uses simple regression analysis and interaction test or Moderated Regression Analysis (MRA) The population in this study includes employees at the Inspectorate Office of Musi Rawas Regency. The sample of this study amounted to 68 employees, selected using a saturated sampling method. The data collection technique used a questionnaire. The results of this study indicate that work discipline has a significant effect on employee performance (Y), as evidenced by the value t_count for the Work Discipline variable (X_1) is greater than the t-table value. This indicates a significant influence between Work Discipline (X_1) on Employee Performance (Y) at the Inspectorate Office of Musi Rawas Regency. So it can be said that the hypothesis is accepted. The next result is that the motivation variable is a moderating moderating variable in the relationship between work discipline and employee performance. Motivation as a moderation variable affects the relationship between Work Discipline (X_1) and Employee Performance (Y). So, Motivation (X_2) as a Moderation variable has an effect on the relationship of Work Discipline (X_1) and Employee Performance (Y) at the Inspectorate Office of Musi Rawas Regency. Thus it can be concluded that the hypothesis is accepted. So it can be said that the Motivation variable (X_2) as a Moderation variable affects the relationship between the Work Discipline variable (X_1) on Employee Performance (Y). Motivation as a moderation variable has an influence on the relationship between work discipline and employee performance. So, giving motivation to employees is important so that giving motivation should be further improved at the Inspectorate Office of Musi Rawas Regency so that employee performance can increase even more.
TRAFFIC CONTROL ASSISTANCE IN CONNECTION NODES: MULTI-AGENT APPLICATIONS IN URBAN TRANSPORT SYSTEMS
Authors: Laichour Hakim , Maouche Salah , Mandiau Rene
Published: February 2021

In this paper, we propose a model for the transport system based on a Hierarchical Multi Agent System (HMAS). This model can be used in order to design a Decision Support System (DSS) to facilitate the work of the regulator by proposing him various regulation actions in every connection node (SARC2: Systeme d'Aidea la Regulation des Correspondances). An optimal organization of the connections is suggested, in normal or disturbed conditions, to avoid loss of time for the passengers. Our model includes a supervisor agent (interface), a connection agent (decision) for each connection node and an acquisition agent (perception) for each regulation station. In our research, we have used MultiAgent Systems (MAS) which adapt themselves perfectly to the distributed systems as in the urban transport networks.

IMPLEMENTATION AND EVALUATION OF RUNTIME DATA DECLUSTERING METHOD OVER SAN-CONNECTED PC CLUSTER
Authors: Oguchi Masato , Kitsuregawa Masaru
Published: February 2021

In this paper, a PC cluster connected with Storage Area Network (SAN) is built and evaluated. In the case of SAN­connected cluster, each node can access all shared disks directly without LAN; thus, SAN­connected clusters achieve better performance than LAN­connected clusters for disk access operations. However, if a lot of nodes access the same­shared disk simultaneously, application performance degrades due to I/O­bottleneck. A runtime data declustering method, in which data is declustered to several other disks dynamically during the execution of application, is proposed to resolve this problem. Parallel data mining is implemented and evaluated on the SAN­connected PC cluster. This application requires iterative scans of a shared disk, which degrade execution performance severely due to I/O­bottleneck. The runtime data declustering method is applied to this case. According to the results of experiments, the proposed method prevents performance degradation caused by shared disk bottleneck in SAN­connected clusters.
UNBIASEDNESS OF FEATURE SELECTION BY HYBRID FILTERING
Authors: Pietruszkiewicz Wiesław
Published: February 2021

In this article we examine characteristics of feature selection algorithms by introducing their aspects important in practice. We will focus on the unbiasedness, analyse it and investigate a robust hybrid method of feature selection, being a composition of several feature filters, that could ensure unbiased results of selection. Using parallel multi-measures and voting, we reduce the risk of selecting non-optimal features, a common situation when we select attributes using single evaluation based on one evaluation criterion. To test this method we selected a personal bankruptcy dataset, containing various types of attributes and one of the popular machine learning benchmarks. By the performed experiments we will demonstrate that an approach of multi-evaluation used for features filtering may lead to the creation of effective and fast methods of features selection with an unbiased outcome.

Published: February 2021

As web users are facing the problems of information overload and drowning due to the significant and rapid growth in the amount of information and the number of users so there is need to provide Web users the more exactly needed information which is becoming a critical issue in web-based information retrieval and Web applications. In this work, we aspire to improve the performance of Web information retrieval and Web presentation through developing and employing Web data mining paradigms. Every search engine has a corresponding database that defines the set of documents that can be searched by the search engine. Generally, an index for all documents in the database is created and stored in the search engine. Text data in the Internet can be partitioned into several databases naturally. Proficient retrieval of preferred data can be attained if we can exactly predict the usefulness of each database, because with such information, we only need to retrieve potentially useful documents from useful databases. For a given query ‘q’ the usefulness of a text database is defined to be the no. of documents in the database that are sufficiently relevant to the query ‘q’. In this paper, we propose new approaches for database selection and documents selection. We also implement these algorithms using .net framework. Our experimental results indicate that these methods can yield substantial improvements over existing techniques.

RELATIVITY INDEX OF THE RELIABILITY OF SPACE SYSTEMS
Authors: Petrov Nikolay
Published: February 2021

According to the special theory of relativity by Einstein, it can be affirmed that two events coincide in space only when objects are shown (or system of objects); according to latter the position of these events is defining. In this way the term “position in space” is relative too. When we talk about the position of one object in space – it’s actually its position among other objects. However, if we have to give answer to the question “where is the current object?” without mentioning about the condition of adjacent objects, it follows that this question will be meaningless. In this article has been done a trial for taking of theoretical dependence, which defines the probability for no-failure of mobile space systems (spacecraft), moving with determinate speed towards an observer on the Earth.
