Ê tre actif dans le grand âge : un plus pour le bien-être ?
Authors: Bickel Jean-François
Published: March 2021

Cet article examine dans quelle mesure la continuité dans les activités de loisir permet de contrecarrer l’effet potentiellement négatif sur le bien-être induit par la fragilité et son aggravation – le bien-être étant considéré dans ses composantes tant cognitive qu’affective. L’analyse empirique se fonde sur une partie des données de l’enquête Swilso-o (Swiss Interdisciplinary Longitudinal Study on the Oldest-Old), consistant en un suivi longitudinal d’une cohorte d’octogénaires, interrogés une première fois en 1994, puis à huit autres reprises jusqu’en 2004. Deux trajectoires de détérioration de la santé, intervenant entre deux vagues d’entretiens, sont observées : l’entrée dans la fragilité et l’aggravation de la fragilité. Chacune de ces trajectoires est d’une part comparée à celle de stabilité de la santé, d’autre part est subdivisée selon l’évolution, dans le même laps de temps, du niveau d’activité – continuité versus déclin. Trois profils sont ainsi définis : stabilité de la santé ; détérioration de la santé avec continuité de l’activité ; détérioration de la santé et déclin de l’activité. Les résultats montrent que par rapport au profil de référence (stabilité), le troisième profil présente un niveau considérablement plus faible de bien-être, alors que celui du deuxième se rapproche de celui du profil de référence. Cet effet positif de la continuité de l’activité est important puisqu’il se remarque pour les deux trajectoires de santé et pour les deux composantes, cognitive et affective, du bien-être. Cette enquête de terrain permet non seulement d’analyser finement les mécanismes qui président au bien-être dans le grand âge, mais surtout d’apporter une contribution d’étape à la littérature principalement anglo-saxonne depuis les années soixante-dix : s’ils se positionnent par rapport aux études qui font référence dans ce domaine, les auteurs ouvrent également de nouvelles pistes d’analyse pour les chercheurs.
Les effets de la réforme de 1993 sur les pensions versées par le régime général
Authors: Bridenne Isabelle , Brossard Cécile
Published: March 2021

La réforme de 1993 a modifié de façon importante les paramètres de calcul des pensions de base du régime général et des régimes alignés ainsi que les règles de revalorisation. Appliquée à partir de 1994, avec une montée en charge s’étalant jusqu’en 2008, cette réforme a une incidence sur le niveau des pensions servies aux retraités depuis 1994. L’objet de cet article est d’évaluer, à partir des données administratives de la Cnav, les effets de cette réforme sur les pensions versées par le régime général. Pour les assurés qui ont pris leur retraite entre 1994 et 2003, la réforme de 1993 se traduit par une pension réduite d’environ 9% par rapport à une pension calculée sans prise en compte de la réforme. Cet écart s’accroît avec les générations au fur et à mesure de la montée en charge de la réforme. À ces effets «paramètres» s’ajoute un effet «revalorisation» de pension, qui augmente avec les années de versement. L’indexation des pensions sur l’inflation a été officialisée par la réforme de 1993. Celle-ci engendre une érosion de la pension par rapport à une revalorisation en fonction du salaire moyen. L’érosion totale cumulée sur la période 1994 à 2003 induit ainsi une perte de pension de 8%. Les répercussions de la réforme de 1993 sur les pensions versées par le régime général, parce que se cumulent les effets «paramètres» et «indexation», sont donc importantes. Les retraités perçoivent des pensions moindres qui, de plus, évoluent moins au cours du temps. Financièrement, la réforme a permis au régime général d’économiser environ 10% des masses de prestations attribuées au titre des droits propres en 2003.
Nouveaux dispositifs de prise en charge, nouveaux métiers ?
Authors: Lechevalier Hurard Lucie
Published: March 2021

La densification de l’action publique autour de la maladie d’Alzheimer, opérée depuis le début des années 2000, a contribué à l’apparition, puis à la consolidation, d’un secteur de prise en charge spécialisé. Le plus souvent intégré au sein d’institutions de prise en charge pour les personnes âgées (Ehpad, SSIAD, hôpitaux gériatriques), ce secteur Alzheimer est constitué de dispositifs dédiés, qui ont une certaine autonomie de fonctionnement. S’appuyant sur une enquête qualitative menée dans l’unité d’hébergement renforcé (UHR) d’un Ehpad, l’article propose d’explorer, à partir du cas des aides-soignantes et des aides médico-psychologiques travaillant dans un lieu d’hébergement, l’articulation de dynamiques de professionnalisation de différentes natures qui traversent le milieu spécialisé Alzheimer. Après avoir décliné le contexte dans lequel s’ancre le développement de pratiques professionnelles autour de la prise en charge de la maladie d’Alzheimer, on verra comment cet exercice en milieu spécialisé peut être investi par les soignantes de première ligne de l’UHR comme lieu d’une évolution professionnelle ascendante, marquée à la fois par une progression de leur qualification, par la conquête nouvelle d’une expertise propre et d’une autonomie d’exercice. Dans un second temps, on mettra en évidence les points sur lesquels les différentes dynamiques de professionnalisation s’articulent avec difficulté, dans la mesure où elles se révèlent en partie contradictoires les unes avec les autres.
La sociologie anglophone des institutions pour personnes âgées
Authors: Brossard Baptiste
Published: March 2021

Depuis les années 1970, de nombreuses recherches qualitatives publiées en anglais tentent de rendre compte et d’analyser la vie en institution d’hébergement pour personnes âgées. Ces recherches portent sur des questions aussi diverses que les contraintes de travail des employés, les distinctions sociales et « ethniques » au sein des établissements, la dimension émotionnelle des soins ou le type d’échanges survenant entre résidents et professionnels. Cet article propose une revue de cette littérature. Après avoir donné quelques clés pour la lecture de ces textes, il présente les grandes orientations de recherche recensées, à partir de travaux particulièrement illustratifs. Il conclut par quelques remarques concernant les spécificités de la recherche francophone et anglophone en la matière et souligne les enjeux contemporains de l’étude des institutions d’hébergement pour personnes âgées à l’échelle internationale.
Effet d’une routine centrée sur l’imagerie mentale et sur l’efficacité du service chez des joueurs de tennis experts
Authors: Dominique Laurent , Coudevylle Guillaume R. , Robin Nicolas
Published: March 2021

Cette étude expérimentale porte sur les effets d’une routine de préparation au service composée principalement d’imagerie mentale (IM) selon une modalité visuelle externe centrée sur la trajectoire de la balle et la zone cible à atteindre. Quarante joueurs experts étaient aléatoirement séparés en deux groupes expérimentaux : contrôle et imagerie. Ils ont réalisé un pré-test (i.e., 25 premières balles de service en condition de match), 20 séances d’acquisition (i.e., pratique physique + IM ou pratique physique seule) et un post-test similaire au pré-test, en condition écologique. Le pourcentage des premières balles de service, la vitesse de ces dernières et un score d’efficacité de celles-ci, évalué par des experts observant les retours de services en condition de match, servaient d’indicateurs de performance et de variables dépendantes. Les résultats de cette expérience montrent notamment une amélioration du pourcentage de première balle chez les participants du groupe imagerie uniquement. Il semble donc bénéfique pour des joueurs de tennis experts d’avoir recours à des routines basées sur la respiration, le rebond de balle et l’imagerie mentale de la trajectoire de la balle et de la cible à atteindre avant de servir des premières balles en condition de match.

Inventory replenishment policies for two successive generations price-sensitive technology products
Authors: Nagpal Gaurav , Chanda Udayan , Upasani Nitant
Published: March 2021

The high technology products come in generations, where the demand for newer technology generations is strongly influenced by the installed base of earlier generations (such as computers, cameras, notebooks, etc). However, the effect of technology substitution on inventory replenishment policies has received little attention in the supply chain literature. In the hi-technology market, consumers' purchasing capability, the utility of a product along with the entry of the advanced generation product influence the market expansion/contraction of the products. In this study, the impact of parallel diffusion of two successive generations' products on inventory policies of the monopolist has been analysed. The demand models have been characterised by considering the life-cycle dynamics for a P-type inventory system. The purpose of this paper is to develop a model for joint pricing and replenishment of technology generation products. The model has been solved by using a genetic algorithm technique. The impact of yearly price drop and the price sensitivity of demand on the profit margins vis-à-vis on replenishment policies has also been studied. The paper also brings forward the dynamics of the launch of newer generations and the pricing strategies on optimal inventory replenishment policies. Numerical illustrations have also been covered in the paper.
Optimal and heuristic algorithms for the multi-objective vehicle routing problem with drones for military surveillance operations
Authors: Ahn Namsu , Kim Soochan
Published: March 2021

During military operations, obtaining information on remote battlefields is essential and recent advances in unmanned aerial vehicle technology have led to the use of drones to view battlefields. However, the use of drones in military operations introduces the new problem of determining travel routes for the drones. This type of problem is similar to the well-known classical vehicle routing problem, but the main difference is its objective function. For maintenance purposes, a minimized difference in travel distances is preferred. In addition, obtaining a shorter route in terms of travel distance is important. In this research, we propose a mathematical formulation and an optimal algorithm for the problem and suggest a simple heuristic to handle the large size instance of the problem. The computational results indicate that this algorithm can solve the real-scale instances of the problem, and the heuristic exhibits good performance even when the instance size of the problem is large.

A Study on Self-Regulating Traffic Light Control Using RFID and Machine Learning Algorithm
Authors: P. Dhivya
Published: March 2021

Traffic control light frameworks are generally used to control and screen the stream of cars through the intersection of numerous streets. As the quantity of street clients always increments and assets gave are constrained, savvy activity flag controller is an exceptionally real prerequisite. One disadvantage of customary methodologies for movement administration is that they don't consider the distinctive valuations of holding up time lessening of the drivers. This chapter proposed another component for versatile activity control utilizing machine learning. In the proposed framework, the authors are utilizing picture sensor in the LED publication which catches the pictures of streets in every one of the bearings and returns the number of head checks of the vehicles to a machine learning calculation. The machine learning calculation is intended to take in the rush hour gridlock thickness without anyone else with first caught picture and consider reference. In this manner, the proposed activity control framework will be an exceptional technique for self-learning and security improving.

Social Media and Health Communication
Authors: Kaya Asuman , Mantar Ozan Bilge
Published: March 2021

The content presented in the media, especially with the element of fear, appears to be the most important factor in the formation and spreading of phobias related to diseases. Especially when it comes to epidemics, the influence of the media increases remarkably. Individuals now use digital media as the initial reference source, especially on issues related to their health, and tend to see social media as a reference platform. However, uncontrolled information, conspiracy theories, and information pollution spread through social media make the subject difficult to understand; online shared manipulative news, excessive and unfounded information cause fear and panic. These posts about vaccines affect the perception and attitude towards vaccines. In this study, the comments and social media posts will be analysed using content analysis and discourse analysis methods in order to reveal the effect of social media in vaccine rejection and hesitation.

Authors: Ulewicz Malgorzata , Zawada Anna
Published: March 2021

In this article, the influence of the addition of the bottom ash to clay on the selected physical and mechanical properties of ceramic composite are discussed. The biomass (80% wood with the addition of 20% coconut shells) was combustion in the fluidised-bed boiler. The tests were carried out on the samples, in which the contents of bottom ash in relation to clay ranged from 5 to 15%. The absorbability, open porosity, apparent density, compression strength and freeze resistance have been determined. The obtained test results indicate that the increase of this bottom ash in clay-ash composite causes the increase of open porosity, absorbability and compression strength, but a reduction in resistance against frost attract.
Use of Allophane as Face Mask Filter for Coronaviruses (Sars-Cov-2)
Authors: Calderon Edward H. Jiménez , Rosero Marco , Diaz Magdalena
Published: March 2021

The traditional mouth cover masks can be made by hand. But with the arrival of the Coronavirus pandemic, these masks have special requirements and we will have to use these until at least 2022. Therefore, the current technological problem is what must be the appropriate filter nanomaterial (cuprum, zinc, zeolite or Allophane) to absorb and/or destroy coronaviruses. In addition, the preparation of this specific purpose mask must be certified, easy to manufacture and inexpensive. Taking these requirements into account, there is a suitable nanomaterial called Allophane, which has active centers of silicon and aluminum (Si / Al), which rapidly absorb micro droplets and nanodrops of water [3, 5] nm. Coronaviruses are microscopically embedded in water droplets. To build an absorbent filter that also destroys coronaviruses, we can use some organic surfactant in optimal proportions and that works cooperatively with Allophane. The physicochemical properties of natural Allophane were studied. For the characterization, analytical techniques were used: Fourier transform infrared spectroscopy (FTIR), BET surface area, X-ray diffraction (XRD), Chemisorption and Atomic Force Microscopy (AFM). In addition, the Navier Stokes 3D equations were studied, which allow us studying molecular dynamics contributing substantively to chemical kinetics describing the process of absorption of water and decomposition of water + coronavirus.

Authors: Kimura Shogo , Ueda Junki , Tsukamoto Hideaki
Published: March 2021

Carbon nanotube (CNT) has been one of promising candidates as a reinforcement in metal matrix composites (MMCs) for its variety of excellent properties such as lightweight, high strength etc. It is necessary to disperse CNT to the level of each one in order to lead to efficiently reflect the excellent essential physical properties of CNT in the composites. This research investigates fabrication processes linked with dry ball milling and cold pressing followed by sintering to uniformly disperse CNT in aluminum (Al) matrix. It was found that dispersibility of CNT were improved with increasing ball milling time based on observation of morphology of mixed powders and the composites using SEM. Vickers hardness and tensile strength of CNT/ Al composites increased with increasing ball milling time up to 24 hours, while they were constant or decreased because of increase of voids in case of longer than 24 hours of ball milling time.

Intraocular Lens Subluxation following Micropulse Transscleral Cyclophotocoagulation
Authors: Alqaseer Basma , Abunajma Muneera
Published: March 2021

We present a case of intraocular lens (IOL) subluxation following micropulse transscleral cyclophotocoagulation (MP-TSCPC) procedure for glaucoma that is resistant to medical therapy. A 71-year-old male presented to his routine glaucoma follow-up appointment and was found to have medically uncontrolled intraocular pressure (IOP) in the right eye. Throughout his visits, the IOP ranged between 26 and 35 mmHg. The IOL was in position without the presence of pseudoexfoliation, and the cup–disc ratio was 0.8 in the right eye. The patient was treated with MP-TSCPC and no immediate complaints or complications were noted post-procedure. However, 5 weeks postoperatively, he presented with IOL subluxation. MP-TSCPC is becoming a popular choice of treatment in lowering IOP. To the best of our knowledge, IOL subluxation has not been reported as a complication. Since the procedure is relatively new, further long-term research is warranted to determine the possible effects and complications.
Evaluation of the PlusoptiX photoscreener in the examination of children with intellectual disabilities
Authors: Raffa Lina H. , Al-Shamrani Abdulrahman , AlQarni Ali , Madani Firas , Allinjawi Kareem
Published: March 2021

PURPOSE:

This study aimed to determine whether the plusoptiX vision screener (PVS) can be used to detect amblyogenic risk factors (ARFs) as defined by the American Association for Paediatric Ophthalmology and Strabismus Vision Screening Committee guidelines (2013) for automated vision screening devices.

METHODS:

In this cross-sectional study, children attending a special needs school underwent screening with the PVS and complete ophthalmologic examinations. Ophthalmologic examinations were used as the gold standard to compute the prevalence, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and testability.

RESULTS:

Forty-four children with special needs (mean age, 8.5 years; range, 4–18 years) were included. The PVS recommended referral of 31 cases (referral rate 70%). Thirty-nine of the 44 children (89%) met the referral-positive threshold for strabismus, reduced vision and/or amblyogenic factors on examination. The plusoptiX had a sensitivity of 40% (confidence interval [CI] 7%–83%), specificity of 78% (CI 55%–85%), PPV of 15% (CI 3%–46%), and NPV of 90.3% (CI 73%–97%). The PVS underestimated refractive errors by 0.67 to 0.71 D in the right (P < 0.001) and left eyes (P = 0.002). Testability was relatively low, with the PVS at 75% compared to the gold standard examination at 100%.

CONCLUSION:

We found that although the plusoptiX photoscreener might be a useful tool in pediatric vision screening, it might not perform as well in children with intellectual disabilities. Utilization of the PVS as a single screening device may fail to identify a considerable proportion of young children with ARFs or amblyopia.

Published: March 2021

PURPOSE:

The aim of this study is to assess the efficacy and safety of ExPress mini shunt in glaucoma patients of Middle Eastern descent.

METHODS:

This is a prospective cohort study. Uncontrolled glaucoma patients were subjected to ExPress mini-shunt implant. Pre- and post-operative glaucoma clinical indices were measured and compared. Both intra- and postoperative complications and surgical success rates were assessed. In addition to comparing a group of combined ExPress mini-shunt implant with cataract surgery versus ExPress mini-shunt implant alone.

RESULTS:

A total of 35 eyes of 31 patients were involved. The most common type of glaucoma was primary open-angle glaucoma in 13 eyes (37.1%). Fourteen eyes (40.0%) were combined ExPress device with cataract surgery. The mean intraocular pressure (IOP) (±standard deviation) at the last visit dropped from 24.6 mmHg (±8.3) to 13.9 mmHg (±4.5). There was a significant reduction in the number of postoperative glaucoma medications from 3.0 ± 0.5 to 1.3 (±0.7). In cases combined with cataract extraction, the patients required fewer anti-glaucoma medications. Complete success was achieved in 22 eyes (63%) and qualified success was achieved in 9 eyes (26%), whereas 4 eyes (11%) were considered a failure. The two most common complications encountered were hypotony (28.6%) and hyphema (11.4%).

CONCLUSION:

Among the studied population of patients, ExPress offers IOP reduction that is comparable to reported rates following standard trabeculectomy. Postoperative hyphema was encountered at a slightly higher rate.

Authors: Coniglio Angela , Rava Alessandro , Fusini Federico , Colò Gabriele , Massè Alessandro , Girardo Massimo
Published: March 2021

Background:

Implants' stability, especially in osteoporosis patients, is a challenging matter. Nowadays, the adoption of cannulated fenestrated screws augmented with polymethylmethacrylate cement (PMMA CSF) is described by some authors. This single-center, retrospective observational study aims to evaluate the long-term effectiveness, reliability, and mechanical performances of this type of screws in osteoporotic fractures.

Materials and Methods:

All the patients surgically treated from January 2009 to December 2019 with PMMA CSF were evaluated and submitted to the inclusion and exclusion criteria. Clinical and radiological evaluations were performed at pre- and post-surgery time and at the follow-up (FU). Loss of correction in the sagittal plane (bisegmental Cobb angle), kyphosis angle of the fracture (fractured vertebral angle), loosening of pedicle screws (screw's apex vertebral body's anterior cortex mean gap called SAAC gap and screw's apex vertebral body's superior endplate mean gap called SASE gap), visual analog scale, and Oswestry disability index scores were evaluated.

Results:

One hundred and sixty-three patients (58 males and 105 females) aged over 65 years affected by vertebral osteoporotic fractures were included in the study. At FU, we do not found significant differences in radiological items in respect to the postoperative period. Only one case of loosening and 18 cases of cement leaking (without neurological impairments) were found. Clinical scores improvement was significant in the interval between preoperative and FU.

Conclusions:

PMMA CSF seems to can guarantee good efficacy and effectiveness in the surgical treatment of vertebral fractures in osteoporosis.

Selecting texts for introductory qualitative research courses can be a challenge given the depth, breadth, and variety of contemporary qualitative inquiry. The new edition of Green and Thorogood’s Qualitative Methods for Health Research presents a great choice for professors teaching courses across the health care spectrum due to its authors’ ability to give students a diverse buffet designed to whet appetites and increase hunger for more qualitative research nourishment.
Life History or How Ethics Can Turn into a Research Methodology: A Review of Ardra L. Cole and J. Gary Knowles' Lives in Context
Authors: Papantoniou-Frangouli Maria
Published: March 2021

Life history research described in the book, Lives in Context by Ardra L. Cole and J. Gary Knowles, constitutes an exercise of scholarship and at the same time of sensitivity towards "the other." The book represents a thorough account of a methodology that integrates the "ethical" as its leading dimension. The book consists of two parts. In the first part of the book the authors develop their approach to life history research. The second part includes articles of other researchers, who have put into practice similar perspectives.

A rendszerváltás jelentős változásokat eredményezett a hazai vidék életében, míg korábban a hazai vidéki jövedelmek világszínvonalúak voltak, addig a rendszerváltás után sereghajtókká váltunk. Az európai uniós csatlakozás és az európai vidéki politika új megvilágításba helyezte a vidéki területeket és az itt élő lakosságot. A tanulmányban a csatlakozás után 15 évvel kerül bemutatásra, hogy milyen szociodemográfiai és gazdálkodási ismérvek jellemzik az európai uniós támogatásban részesülő családokat a Dél-alföldi Régióban.
Evaluating an e-Portfolio implementation with early adopters using Appreciative Inquiry
Authors: Symonds Elizabeth
Published: March 2021

The benefits of using e-Portfolio tools to enhance the student learning experience have been widely reported. These benefits include opportunities for reflection, flexibility, connectivity and integrated learning. In recognition of these potential benefits to students, the University of Worcester adopted an institution-wide e-Portfolio system which is available to all staff and students at the university.In order to maximise the potential of this system, a study was carried out to elicit staff and student views as to what the benefits of using an e-Portfolio were. It is all too easy to focus on the negative aspects when struggling to implement a new initiative, particularly involving technology. With this in mind a conscious effort was made in the evaluation to value and learn from the positive experience of users.Feedback was sought from early adopters of the system in an Appreciative Inquiry framework in order to ascertain the benefits of using such a system, to both staff and students, and to inform future practice and recommendations. Findings of the inquiry indicated that there are three significant factors which can influence effective practice with e-Portfolios: tutor engagement, support and embeddedness. Whilst both staff and student users found the use of e-Portfolio beneficial for the teaching and learning process, the issues that were raised by each group were subtly different.This paper will discuss how staff and students perceive the benefits of using an e-Portfolio and the factors that can influence engagement. It will also consider the implications of using an Appreciative Inquiry approach in institutional research.
An evaluation of the impact of e-Portfolio supported pedagogic processes on students' reflective capacity
Authors: Wilson-Medhurst Sarah , Turner Andrew
Published: March 2021

This paper describes research evaluating pedagogical strategies and processes that develop the reflective capacity of students. An Appreciative Inquiry framework was adopted to establish, from a student perspective, what works or 'gives life' in terms of supporting and encouraging a reflective capacity. The context was an undergraduate module with an explicit focus on employability and 'transition-out' of university. Students were drawn from a range of courses as diverse as Performing Arts, Business Management, Engineering and Computing Science. This presented both challenges and benefits. The module utilised an e-Portfolio tool (PebblePad) linked to formative and summative assessment to support students in their learning development, including reflection around personal and career development. Key elements of the module which developed the reflective capacity of students, evident in appreciative feedback, were a personal statement first assignment linked to interdisciplinary group work and activities which scaffold the reflective process. The paper discusses the pedagogical processes involved and highlights areas for further research.
Taking Concept Mapping (CM) forward with socially mediated structured approaches
Authors: Jankowska Maja
Published: March 2021

There is substantial research evidence (e.g. Nygaard and Holtham, 2008, 2009) to indicate that studentsÃ¢â¬â¢ active engagement in co-constructing knowledge, and taking responsibility for their own learning, is key to their achievement and development. This chapter will explore Concept Mapping (CM) not only as one means of gathering research data but also Ã¢â¬â and most importantly Ã¢â¬â as a powerful technique to support reflection and offer space for internal dialogue about each studentÃ¢â¬â¢s personal development.Concept maps were gathered from a sample of students on a postgraduate business programme. In addition to the data from the concept maps themselves, semi-structured individual interviews were conducted with part of the sample to follow-up and illuminate the CM process, as they seemed to deepen the reflective capacity of those students through more structured and socially-mediated activity.Findings from this research indicate that CM introduced within a socially supported and structured process can enable the shift from teacher reliance to student autonomy. It is also suggested that students do need structured and scaffolded activities in the area of Personal Development Planning (PDP), especially in reflective tasks, as they are often not sure how to approach this area of learning.
Building research capacity in a practitioner community: framing and evaluating the 'National Action Research Network on Researching and Evaluating Personal Development Planning and e-Portfolio Practice'
Authors: Peters John
Published: March 2021

This paper evaluates key aspects of the National Action Research Network on Researching and Evaluating Personal Development Planning and e-Portfolio Practice (NARN). This was a National Teaching Fellowship Scheme funded project which ran from 2007-1010 and involved sixteen English Higher Education institutions (HEIs). The context, purposes, theoretical underpinnings and framework for the NARN are briefly explained before the experience of members is explored through an analysis of their own accounts. The NARN was proposed in response to widespread calls for more research evidence to underpin our understanding and implementation of Personal Development Planning (PDP) and e-Portfolio practices, taking its lead from Clegg's (2004) invitation to produce more researched examples of situated PDP and e-Portfolio practice. The NARN was primarily a capacity-building project aimed at developing a community of PDP and e-portfolio practitioners into practitioner researchers. Borrowing heavily on ideas of community and participative inquiry as well as concepts about developing communities of practice, the project placed an emphasis on promoting collegiality, a sense of belonging and the establishment of the project as a safe space in which to discuss research work. It is evaluated here through the thematic analysis of a particular data set of twelve anonymous accounts provided by project members. The NARN project's emphasis on process rather than product or output, mark it apart from most Higher Education (HE) learning and teaching funded projects. Its success carries an important lesson for fundholders, educational developers and HE managers about the funding of more process-based learning and teaching development in HE. It also provides a possible framework for similar capacity-building projects across other communities.
Capturing and communicating advanced mathematical activity
Authors: Samuels Peter
Published: March 2021

Unlike most other subjects, mathematical activity resides almost entirely within the cognitive processes of a mathematics practitioner and is therefore difficult to characterise. Despite recent interest, the nature of advanced mathematical activity remains something of a black box to educational researchers. In addition, the production of advanced mathematical texts, such as theses or journal articles, is often divorced from mathematiciansÃ¢â¬â¢ experiences of creating mathematics which can lead them to a sense of personal alienation from their work. This article proposes four practical techniques for capturing advanced mathematical activity. The timing of the use of these techniques is compared against a model of mathematical creativity and the writing process. The establishment of a new genre for communicating advanced mathematics is proposed which combines the product of the activity with the process of creating it.
