L’intégration d’un agent virtuel à un site Internet : une modification sensible des intentions comportementales et du comportement réel de l’internaute
Authors: Notebaert Jean-François
Published: September 2019

Les agents virtuels animés sont aujourd’hui couramment utilisés sur Internet. Il s’agit d’une interface favorisant une interaction entre l’entreprise et les internautes. Cet article cherchera à définir, grâce à une première étude quantitative, si l’intégration d’un agent virtuel sur un site Internet permet de jouer positivement sur la confiance, la satisfaction et les intentions comportementales du consommateur. Puis, une seconde étude quantitative permettra d’analyser le comportement réel des internautes et l’incidence d’un agent virtuel sur le temps passé sur le site et la stratégie crosscanal. En conclusion, des contributions théoriques et managériales concernant l’utilisation des agents virtuels seront proposées.
La compliance : une inflation normative au carré ?
Authors: Bouthinon-Dumas Hugues
Published: September 2019

La compliance est une technique de gestion utilisée par de nombreuses entreprises pour faire face notamment au défi de l’inflation normative. L’analyse approfondie des relations entre inflation normative et compliance montre que la compliance est elle-même à l’origine de nouvelles normes qui s’ajoutent à celles dont elle vise à favoriser l’application et le respect. La compliance alimente ainsi paradoxalement une forme d’hyperinflation normative.

L’existence filiale, défi de l’Église-Famille de Dieu
Authors: Diouf Jacques
Published: September 2019

L’édification de l’Église-Famille de Dieu en Afrique ne peut se faire sans prendre en charge le défi d’une existence filiale, traduction concrète du don de notre adoption filiale dans le Christ lui-même don de Dieu. Cette traduction implique un processus de « christo-conformation » inscrivant les chrétiens dans le don du Christ, par la puissance de l’Esprit Saint qui intériorise au concret la ressemblance filiale au Christ. Là où tout est filial, s’ouvre la possibilité de suivre ce chemin.

L’art face à la barbarie
Authors: Abdelouahed Houria
Published: September 2019

Contrairement aux attentes des peuples arabes assoiffés de liberté et de démocratie, le soulèvement en Tunisie - qui eut pour effet la chute du régime du dictateur Ben Ali - coïncide avec l’émergence en Syrie et en Irak de Daesh dont la férocité extermine humains et vestiges et prône le triomphe de la satisfaction pulsionnelle brute et la destructivité. L’auteure, suivant les pas du sculpteur Selim rendant visibles les effets du trauma sur le corps des humains contraints à prendre le chemin de l’exil, relit Al-Kitâb ( Le Livre ) du poète Adonis qui rappelle l’éternel retour du désastre dans cette contrée du monde (qui s’appelle monde arabe) qui reste accrochée à un legs fortement idéalisé car n’a jamais fait objet d’une science historique. Aussi Al-Kitâb s’avère-t-il une véritable mise en pièces de cet héritage. Le poète comme le sculpteur nous mettent sous les yeux le patrimoine hanté par l’empiètement et l’épouvante. Face à la cruauté de l’Histoire, la cruauté du style de l’artiste. Toutefois, ré-écrivant, re-modelant, l’artiste transforme la douleur en épopée et le monde en une œuvre.
Musique, Pouvoir et Identité collective
Authors: Dakovanou Xanthoula
Published: September 2019

Dans cet article, nous interrogeons la relation entre musique et pouvoir : la musique peut être utilisée pour promouvoir ou bien pour combattre l’idéologie dominante d’une façon très effective. Pour cette raison le pouvoir essaie de contrôler la musique et la mettre à son service. Nous analysons, d’un point de vue psychanalytique, les raisons pour lesquelles la musique possède un tel pouvoir et nous examinons le lien de la musique à l’Idéal du Moi. À travers de nombreux exemples historiques et musicologiques, nous défendons l’idée que la musique incarne d’une façon très efficace les idéaux collectifs groupaux d’une société donnée, y compris dans le domaine de la religion et du pouvoir politique. Nous démontrons aussi l’idée que les idéaux individuels et groupaux sont reflétés de façon très précise dans la structure musicale.
Poésie confisquée, maudite poésie – deux avatars de la poésie engagée
Authors: Houser Éric Pierre
Published: September 2019

L’engagement en littérature a été traité par Jean-Paul Sartre. Nazisme et stalinisme en présentent un visage particulier en la personne de deux poètes, Friedrich Hölderlin côté allemand (cent ans après sa mort, les nazis le confisquant au service de leur idéologie), Ossip Mandelstam côté russe (Staline le faisant emprisonner après qu’il eut écrit une épigramme contre lui). Pendant la deuxième guerre, Gertrude Stein écrit son roman Mrs Reynolds , qui fait d’Hitler et Staline des personnages de fiction.
La création face à la répression : l’œuvre d’art comme poïèsis de la conscience
Authors: De Vincenzo Mario , Mora Maira
Published: September 2019

À partir d’une analyse esthético-politique d’une œuvre d’art réalisée pendant la dictature chilienne, nous étudierons les rapports complexes établis entre l’art et le pouvoir. L’étude du discours aliénant du régime et de ses implications subjectives et politiques nous permettra de comprendre comment l’œuvre d’art s’inscrit dans le socius , en opposant aux silences et à la négation du discours d’État un travail de figurabilité qui favorise tant la prise de conscience que la construction mémorielle.

Le rôle du politique dans la décomposition urbaine et territoriale
Authors: Dorier-Apprill Élisabeth
Published: September 2019

En 1993-1994, dans l'été 1997, puis fin 1998, trois sanglantes « guerres des milices » accompagnées de pillages et de violences criminelles de plus en plus systématiques ont d’abord ravagé la capitale congolaise avant de se propager dans les régions sud du pays, aiguisant des tensions etnorégionales latentes manipulées par les chef de partis politiques. La géographie des combats et des pillages, les migrations forcées des habitants, ont révélé brutalement les tensions et les déséquilibres sous-jacents de la structure urbaine, les accentuant jusqu à la caricature et au tragique. Les guerres imposent donc une relecture a posteriori d’un système socio-spatial urbain qui concentre autant les enjeux politiques nationaux que locaux. L'exemple le plus révélateur est celui du quartier de Bacongo, marquépar une forte conscience identitaire de caractère ethno-régional. Fiefde l’un desprincipaux partis politiques et contrôlé pendant quatre ans par sa milice, il a été détruit par l’armée et la milice cobra durant l’hiver 1998-1999. L’impact de la violence politique s’étend désormais à tout le sud du pays, coupant Brazzaville de ses liaisons avec le littoral et Pointe Noire, la capitale économique.

Earthquake hazard assessment in Albania
Authors: Sulstarova Eduard
Published: September 2019

L'Albanie est un pays dont l'activité sismique atteint des niveaux proches de ceux de la Grèce et de la Turquie. Avec la croissance de la population et l'urbanisation, les enjeux économiques de la prévention des séismes deviennent de plus en plus importants. Une politique efficace de prévention et de protection passe d'abord par une bonne connaissance des aspects historiques et géographiques de la sismicité (importance de la cartographie pour établir une régionalisation sismique), et par l'étude des facteurs géologiques. Cette étude vise à la mise en relation des données structurales et tectoniques. Elle combine la cartographie des foyers, la cartographie des failles, les levers de cartes néotectoniques, de cartes historiques des épicentres, des intensités, des magnitudes. Toutes ces méthodes permettent d'aboutir à un zonage sismique régional, à l'échelle du pays, indispensable pour répartir les efforts à accomplir en matière de prévention et de protection.
Dans les geôles du roi
Authors: Claustre Julie
Published: September 2019

Associée aux malheurs du jeune Charles Dickens, la prison pour dette est souvent considérée comme une sanction implacable de la pauvreté, typique de l’Angleterre victorienne, alors qu’elle fut en France un moyen normal, sinon fréquent, de contraindre les endettés à satisfaire leurs créanciers jusqu’en 1867 et qu’elle reste de nos jours un moyen dont l’État use à l’égard de certains de ses débiteurs. Dans les geôles du roi, dès le xive siècle, on enfermait les débiteurs jusqu’au paiement de leurs dettes ou jusqu’à l’accomplissement de leurs obligations contractuelles. Pour la première fois, ce livre retrace avec précision les débuts de cette institution, entrée dans le droit royal en 1303, et, en se fondant sur les archives médiévales des tribunaux et prisons du Châtelet et du Parlement de Paris, rappelle sa genèse aux xive et xve siècles.

Comment pouvait-on faire arrêter son débiteur ? Qui étaient ces prisonniers pour dette ? Comment « tenaient-ils prison » ? Comment en sortaient-ils ? Dans quels termes cette fonction de coercition a-t-elle été conçue par les juristes et les magistrats ? Telles sont les questions qui sous-tendent cette enquête sur l’entrée de l’emprisonnement pour dette dans le droit royal et la pratique judiciaire français. Jour après jour, la prise du corps des endettés a imposé la sujétion des débiteurs et des créanciers à leur roi, aussi sûrement que des contraintes et des peines extrêmes comme la question, les mutilations et la peine de mort. Appliqué d’abord aux laboureurs, aux ouvriers et aux artisans de l’Île-de-France qu’il rappelait à la discipline du contrat, l’emprisonnement pour dette se situe à la croisée de l’histoire de la souveraineté de l’État et de celle de l’émergence de la « question sociale » à la fin du Moyen Âge.
Transformation of the Dissertation
Authors: Cresswell-Yeager Tiffany J. , Bandlow Raymond J.
Published: September 2019

To increase success and graduation rates, research shows that doctoral programs must adapt to changes in how instruction is managed and delivered, and must include options that recognize and facilitate discipline mastery without compromising their integrity or the quality of their degrees. This chapter explains a new path to doctoral degree completion, one that minimizes arbitrary time-frames and emphasizes discipline mastery through rigorous coursework and graduate-level research. The authors recommend a new model for successful completion of the dissertation within the Doctorate of Education (Ed.D.) through evidence-based practice. This model implements structured mentoring and the transformation of dissertation research from an end-of-program destination to a program-embedded process. This chapter will provide a discussion of four evidence-based strategies for improved success for doctoral students following this type of pathway to dissertation completion.
Gains From the Rehabilitation of Nursing to the Elderly With the Mobility Deficit by Femur Fracture
Authors: Soares Maria João , Ferreira Rogério Ferrinho , Vieira João Vítor
Published: September 2019

The objective of this chapter is to identify the gains associated with rehabilitation nursing care implemented in the elderly person with mobility deficit of the fractured femur. An integrative literature review with a qualitative synthesis retrospectively by 2014 was used. Older femur fractures undergo physical changes that affect their motor function and cause dependence in their activities of daily living (ADLs). From the specialized intervention in rehabilitation nursing, sensitive gains in mobility, functional independence in ADLs, hospital admission and rehabilitation time, quality of life and mortality rate, and health expenditures emerge were found. Fracture of the femur is usually associated with a fall from a height and occurs mainly in independent females in ADLs. In this population, gains that are sensitive to rehabilitative nursing care are recognized in the scientific evidence. The rehabilitation nurse thus has a relevant role in the qualification and quality of life of the person, with evident implications in the elderly care, in an institutional and community context.
Challenges in Estimation of Beta
Authors: Azimova Tarana
Published: September 2019

Capital asset pricing model (CAPM) brings deep intuitive understanding of the relationship between expected return and risk. Unfortunately, the empirical record of the CAPM has not been satisfactory since its commencement. The empirical testing of CAPM is void in most cases due to the use of an inefficient index as a proxy for market portfolio. Plausible tests require a well-diversified market portfolio which so far has been unfeasible to obtain. Lack of validity in empirical records has been caused by complexity in exerting valid estimations of the beta coefficient. This chapter judges which of the indices provides investors the best beta forecast and questions which time period should be selected for beta calculation. This chapter reveals that the choice of return intervals causes variations in beta estimation of the security. Applying higher frequency has an advantage in that it increases the number of observations, but a shortfall is that beta tends to have substantial bias with shorter return intervals used.

Technical and Hedonistic Variables of Online Visual Merchandising
Authors: Bigi Alessandro , Bonera Michelle , Corvi Elisabetta
Published: September 2019

This study looks for a correlation between visual hedonistic and technical variables and site success, simultaneously establishing whether there are any recorded evolutionary aspects of technical variables. A mixed method approach was adopted and the analysis was divided into the following phases: content analysis on technical and hedonistic characteristics; traffic analysis, analysis of the position of websites in relation to data traffic using a size reduction technique; cross-analysis of results obtained in the two previous phases to observe the cluster structure from a point of view of data traffic. The results state that there is no clear correlation between technical and hedonistic qualities of an e-commerce site in the apparel industry and the popularity and attractiveness of their site, and therefore, the authors cannot confirm the four proposed hypotheses.

A Lane Identifying Approach of the Intelligent Vehicle in Complex Condition
Authors: Wu Botao , Wang Huijuan
Published: September 2019

Lane identification by intelligent vehicles in some common complicated conditions is a key technique. The parabola model of lane boundary is established first for fitting the curved lane boundary, and the objective function is used to estimate the fitting quality of the lane boundary is designed with the grayness character and grads character of the lane boundary in a gray image. To improve the speed of the identifying algorithm, the ant colony algorithm is applied to lane identifying, and with the guidance of the designed objective function, the positive feedback of hormone will consistently allow the search the best path within the searching region of interest as soon as possible, thus, the lane boundary is found. The method can effectively eliminate the negative effect of illumination conditions or shadows of trees, etc., and identify linear or curving lane boundaries exactly. The pretreatment to image is found and the searching region of interest is set, so the real-time identifying is greatly improved.

Authors: Wang Tianlei , Tan Nanlin , Zhang Chi , Li Ye , Zhai Yikui
Published: September 2019

Efficient tracking of heavy loads is the overall goal for overhead cranes in the workplace. This article presents a new way to simply and effectively track overhead cranes at higher speeds. A real-time tracking method is presented here to make tracking the overhead crane load not only accurate, but also faster. First, to observe and extract details and information to use in the appearance model, a measurement matrix is constructed here. Second, a sparse representation is also adopted to track dynamic overhead crane features effectively. Finally, a Naïve Bayesian classifier has been used as a binary classification in a compressed domain. Experiments on the VOT2013 benchmark and constructed data Cranes40, the results demonstrate that the presented sparse representation tracking method can successfully track cranes in real-time.
Exploring Magnetorheological Brake-Based Anti-Lock Brake System for Automotive Application
Authors: Kamble Romit , Patil Satyajit
Published: September 2019

The present work explores a magnetorheological brake (MRB)-based anti-lock brake system (ABS) proposed for a vehicular application. Because of its quick response time, MRB is being considered as a substitute for the conventional hydraulic brake (CHB), commonly used for road vehicles. ABS is used along with CHB to prevent wheel lockup due to severe braking and thereby maintain the stability of the vehicle. This work envisages ABS for a vehicle using MRB instead of CHB. The braking maneuver for a typical mid-size car with and without ABS is simulated in a MATLAB environment. Both versions, a CHB-based ABS and a MRB-based ABS are considered in simulations. The braking performance in terms of stopping time and stopping distance is estimated. A PID and a Fuzzy controller are proposed for improving the control performance of the brake system. The comparative analysis based on the simulations helps make estimations for MRB-based ABS performance.
Theoretical and Experimental Free Vibration Analysis of a Loaded Curved Beam With Moving Boundaries
Authors: Ghuku Sushanta , Saha Kashi Nath
Published: September 2019

The present article theoretically and experimentally investigates free vibration characteristics of generalized curved beams with moving boundaries. The dynamic behavior is characterized about deformed configuration, attained under different concentrated loads, and rigidly connected to the midpoint of the beam. The coupled static and dynamic analysis of the geometric nonlinear problem is decomposed into two parts: the static problem dealing with large deformed configuration and the dynamic problem dealing with small amplitude free vibration of the deformed configuration beam. The analysis is carried out incrementally in embedded curvilinear coordinate frames using variational principle. The governing equation of the static problem is derived for a combined effect of bending and center line extension. The governing equation for free vibration is derived at the particular configuration of the updated beam geometry, using Hamilton's principle. The comparison between the numerical and experimental results successfully validates the proposed semi-analytical model and leads toward some meaningful observations.
A Novel Method for High Capacity Reversible Data Hiding Scheme Using Difference Expansion
Authors: Mukherjee Subhadip , Jana Biswapati
Published: September 2019

Data hiding techniques are very significant in the research area of information security. In this article, the authors propose a new reversible data hiding (RDH) scheme using difference expansion. At first, the original image is partitioned into 3 × 3 pixel blocks, then marked Type-one and Type-two pixels based on their coordinate values. After that, the authors find correlated pixels by computing correlation coefficients and the median of Type-one pixels. Next, secret data bits are embedded within Type-two pixels based on correlated pixels and Type-one pixels based on the stego Type-two pixels. The data extraction process successfully extracts secret data as well as recovers the cover image. The authors observed the effects of the proposed method by performing experiments on some standard cover images and found significantly better result in terms of data hiding capacity compared with existing data hiding schemes.
Computational Modelling in Epidemiological Dispersion Using Diffusion and Epidemiological Equations
Authors: Lambrou George I. , Hatziagapiou Kyriaki , Toumpaniaris Petros , Ioannidou Penelope , Koutsouris Dimitrios
Published: September 2019

Although a considerable amount of knowledge is gathered concerning diseases and their transmission, still more is to learn on their mathematical modelling. The present work reviews the existent knowledge on models of epidemiological dispersion, the creation of a new form of an epidemiological diffusion equation, and the subsequent application of this equation to the investigation of epidemiological phenomena. Towards that scope, the authors have used mathematical models which have been previously reported, as well as algorithmic approaches of stochastic nature for the solution of complex functions. In particular, they have used dynamic programming algorithms, Robbins-Monro and Kiefer-Wolfowitz stochastic optimization algorithms, Markov chains and cellular automata. The modified diffusion equation could potentially provide a useful tool to the investigation of epidemiological phenomena. More research is required in order to explore the extent of its possibilities and uses.
Modeling Uncertainty Based on Spatial Models in Spreading Diseases
Authors: Zimeras Stelios , Matsinos Yiannis G.
Published: September 2019

Lately, spatial models have become a powerful, necessary statistical tool to estimate parameters where data are represented by regions of interests using the window method . Estimation processes based on the high dimensionality of the data have become difficult to implement especially in cases where variability in the spatial models is the main task to investigate. Variability between spatial models considering hierarchical levels of scale, most of the time, involves errors leading to uncertainty in spatial regions. Solving the problem with uncertainty via the estimation of errors in spatial models, complex models could be simplified in easiest ones and important decisions for the quality of data could be taken.

Published: September 2019

MixAR, a full-stack system capable of providing visualization of virtual reconstructions seamlessly integrated in the real scene (e.g. upon ruins), with the possibility of being freely explored by visitors, in situ, is presented in this article. In addition to its ability to operate with several tracking approaches to be able to deal with a wide variety of environmental conditions, MixAR system also implements an extended environment feature that provides visitors with an insight on surrounding points-of-interest for visitation during mixed reality experiences (positional rough tracking). A procedural modelling tool mainstreams augmentation models production. Tests carried out with participants to ascertain comfort, satisfaction and presence/immersion based on an in-field MR experience and respective results are also presented. Ease to adapt to the experience, desire to see the system in museums and a raised curiosity and motivation contributed as positive points for evaluation. In what regards to sickness and comfort, the lowest number of complaints seems to be satisfactory. Models' illumination/re-lightning must be addressed in the future to improve the user's engagement with the experiences provided by the MixAR system.
A Hybrid Hindi Printed Document Classification System Using SVM and Fuzzy
Authors: Puri Shalini , Singh Satya Prakash
Published: September 2019

This article introduces a new advanced tri-layered segmentation and bi-leveled-classifier-based Hindi printed document classification system, which categorizes imaged documents into pre-defined mutually exclusive categories by using SVM and Fuzzy matching at character and document classifications, respectively. During training, the improved and noise-free image is segmented into lines and words by profiling. Then it obtains Shirorekha Less (SL) isolated characters along with upper, left and right modifier components from the SL words. These components use their locations and inter character-modifier component distance to get associate with their corresponding characters only. Further, confidence values of all characters are calculated with SVM training and all characters are mapped into Romanized labels to generate the words. Finally, documents are classified by Fuzzy based matching of Romanized detected words and predefined classes. The average execution times of SL characters are 0.22675 sec. and 0.20375 sec. and classification accuracy are 74.61% and 80.73% for training and testing, respectively.
Real Time Scheduling Optimization
Authors: Boutekkouk Fateh
Published: September 2019

This article deals with real time embedded multiprocessor systems scheduling optimization using conventional and quantum inspired genetic algorithms. Real time scheduling problems are known to be NP-hard. In order to resolve it, researchers have resorted to meta-heuristics instead of exact methods. Genetic algorithms seem to be a good choice to solve complex, non-linear, multi-objective and multi-modal problems. However, conventional genetic algorithms may consume much time to find good solutions. For this reason, to minimize the mean response time and the number of tasks missing their deadlines using quantum inspired genetic algorithms for multiprocessors architectures. Our proposed approach takes advantage of both static and dynamic preemptive scheduling. This article has the developed algorithms on a typical example showing a big improvement in research time of good solutions in quantum genetic algorithms with comparison to conventional ones.

The objective of this study was to verify the activity of invertases in Estilosantes under the influence of cultivation systems and nitrogen fertilization in two seasons. The experiment was conducted in the Xaraés area, where Estilosantes was planted according to a 2 x 2 factorial scheme with two cultivation systems (monoculture and mixed pasture) in the absence or presence of fertilization (75 kg of N ha-1). A randomized block design with four replications was used. The neutral cytosol (Inv-N), vacuole acid (Inv-V) and cell wall acid (Inv-CW) invertase activity and reducing sugar contents in the leaves and stems were evaluated and analyzed by a 5% probability F-test. The interaction between cultivation systems and nitrogen fertilization was significant for Inv-N in the leaves in the summer, such that greater activity occurred in response to the mixed pasture system and nitrogen fertilization. Nitrogen increased the activity of the Inv-N in the stem in both periods, increased the activity of Inv-V in the leaf in the summer, and decreased the activity of Inv-CW in the fall. This cultivation system influenced the activity of Inv-N regardless of the period of the year and did not interfere with the activities of the acid invertases. The invertases did not show regular changes in relation to nitrogen fertilization.

The productive capacity of soybeans is associated with the adaptation of the culture to the cultivation environment. Factors such as a high number of pods, the weight of a thousand grains, and grain number are essential factors in determining cultivars of high productive potential. The launching of new varieties associated with new technologies makes it necessary to know the performance of these varieties in different growing environments. This study aimed to analyze the agronomic performance of transgenic soybean cultivars under Cerrado conditions. The experimental design used completely randomized blocks; six of the twelve cultivars used RR1 technology and the remaining six used RR2BT. The cultivars were grown in five distinct locations in the southwest region of Goiás. The results demonstrated no increments in the grain yield of the RR1 or RR2BT technologies and the precocity of the cultivars also did not favor an increase in grain yield. The localities of Jataí and Rio Verde did not influence the cultivar cycle.

Use of variable-pitch rotors was compared against variable-RPM rotors on a 2-kg (20 N) quadcopter in simulation. To generate 5 N of thrust in hover while maintaining a 2:1 maximum thrust-to-weight ratio, the variable-pitch rotor required 29% more power. At low climb rates the variable-RPM
rotor requires less power, but near its maximum rate it required more power than the variable-pitch rotor. The maximum climb rate for the variable-pitch rotor was up to 70% greater than that of the variable-RPM rotor. A quadcopter equipped with variable-pitch rotors required more power to
operate compared to the aircraft with variable-RPM rotors over its operational airspeed range. The variable-pitch quadcopter required 30% more power at best-endurance speed and had 18% less range than the variable-RPM quadcopter (at maximum-range speed). The 1/rev root drag shear was 42% larger
for the variable-RPM rotor, and the 2/rev H- and Y-forces were 37% and 50% larger. The 2/rev thrust vibration was 6.5% smaller for the variable-RPM rotor, and the hub pitching and rolling moments were 11% and 9% smaller, respectively. Unlike the quadcopter equipped with variable-pitch rotors,
the quadcopter equipped with variable-RPM rotors experienced a beating phenomenon in the aircraft-level vibratory loads.

Beta thalassemia is a hereditary disorder resulted from mutations in the β globin gene leading to alpha/beta imbalance, ineffective erythropoiesis, and chronic anemia. Three types have been defined, based on the degree of reduced beta-globin chain synthesis and clinical phenotype: major, intermedia and minor (heterozygote carrier state). Beta thalassemia intermedia is characterized by heterogeneity for the wide clinical spectrum of various genotypes and a wide range of presentations. The genotypes of beta thalassemia intermedia are much complicated referring to β+/β+,β+/β0, Hb E/β0, β0/β0 compounding alpha thalassemia and so on. In this present case, we reported a rare beta thalassemia intermedia genotype of double heterozygosity for poly A (A>G) and CD17(A>T) indicated of β+/β0 in a Chinese family.

The aim of this study is to explore the expression of osteopontin (OPN) and its relationship with prognostic factors and survival in diffuse large B cell lymphoma (DLBCL). A tissue microarray was performed for immunohistochemical evaluation. Contingency tables were analyzed for trends; chi-square test was used to determine differences between groups. Univariate and multivariate Cox proportional hazards-regression analyses were performed to evaluate the impact of prognostic factors on survival. Expression of OPN was observed in 28%. It was different in non-germinal center DLBCL (P=0.04). The mean overall survival (OS) was lower in patients with positive OPN expression (19.762; CI 95% 14.269-25.255) it was not significant (P=0.123). It is not possible to establish a clear relationship between the expression by immunohistochemistry of osteopontin and a poor prognosis but it would be important to complement the analysis with other techniques as PCR or NGS that allow us to assess the influence of the isoforms and post-translational modifications of OPN on the biological behavior of DLBCL. Our findings indicate that OPN expression could be associated with a more aggressive variant of lymphoma: non-germinal center DLBCL.

Anemia is one of the most common problems in chronic kidney disease (CKD). In several cases, despite comprehensive investigations, definite causes of anemia frequently remain unknown. We aimed to analyze the factors that possibly affect anemia in CKD patients who were referred for hematology consultation. A total of 87 patients were retrospectively included in the cohort. Forty-four cases were excluded, 30 cases with unavailable intact parathyroid hormone (iPTH) data, 11 cases with bone marrow diseases (8 Pure red cell aplasia, 3 Myelodysplastic syndrome) and 3 cases with thalassemia. Totally, 43 patients were analyzed. Patients with high iPTH had significantly lower Hemoglobin (Hb) level and required higher dose of erythropoietin stimulating agents (ESAs) compared with normal iPTH group (Hb 8.29 vs 9.24 mg/dL, p=0.032 and ESAs dose of 16,352.94 vs. 12,444.44 U/ week, p=0.024). In univariate followed by stepwise multivariate analysis, serum phosphate (PO4) was significantly associated with lower Hb level (p=0.01 and p=0.013, respectively). Hb level was inversely correlated with iPTH and PO4 level (r=-0.54, p<0.001 and r=-0.47, p=0.05; respectively). Mineral disequilibrium is an important factor associated with anemia in ESA hyporesponsive CKD. Hyperphosphatemia and secondary hyperparathyroidism are significantly correlated with low Hb. Therefore, we strongly suggest correction of these mineral disequilibrium factors prior to performing bone marrow study.

Mycobacterium goodii has only rarely been reported to cause invasive disease in humans. Previously reported cases of M. goodii infection have included prosthetic joint infections, pacemaker pocket infections, and pneumonia. We present a case of bacteremia with concomitant pulmonary septic emboli that developed in a 32-year-old woman with an indwelling central line. The line had been placed one year previously for intermittent treatment with intravenous, broad-spectrum antibiotics, administered by an outside physician for the treatment of symptoms attributed to chronic Lyme disease. The long duration of antibiotic use and presence of a central venous catheter predisposed the patient to this infection. Patients should be counseled regarding the serious risks of long courses of broad-spectrum intravenous antibiotics via central venous catheters to treat non-specific symptoms attributed to Lyme disease.

Authors: Donald Iain , Scott-Brown Kenneth
Published: September 2019

This paper focuses on the virtual reality (VR) project Their Memory and details the development and evaluation of virtual reality environments and experiences with respect to its impact on young people (14-35 demographic) with the narratives of veterans in Scotland. As part of the AHRC Immersive Experiences program, Their Memory was created to explore how game design techniques and immersive technology could be used to enhance existing historical research and enrich narratives to bring expansive experiences to hard-to-reach audiences. The project worked directly with the veterans’ charity, Poppyscotland, to create an environment and experience that would resonate with new audiences, and explore documentary and storytelling techniques for the commemoration of war and conflict. The design of the project evolved through co-design sessions with veterans and young people and culminated in the creation of a short, thought-provoking, narrative-driven experience. The VR experience enabled players to connect with the memories of veterans in Scotland and exploring the different conflicts or situations they experienced and how they make sense of them. The project brought together cross-sector expertise to research how immersive experiences can help memory-based organizations in engaging with wider audiences, raise awareness, and diversify current learning outputs. The paper details the design and development of the Virtual Reality project, through co-design, and how this engaged the audience and evolved the experience created. The paper includes a summative evaluation of events conducted with schoolchildren to assess the project and concludes with how the project evidences impact upon audiences and the potential for both technology and the experience.
