Interagir avec le consommateur responsable
Authors: Makaoui Naouel , Taphanel Ludovic 
Published: August 2018

Cette recherche questionne les tensions identitaires et les stratégies de résolution des consommateurs responsables lorsqu’ils sont confrontés à leur comportement réel d’achat. Elle participe d’une reconceptualisation du traditionnel décalage entre attitudes et comportements de ces consommateurs en mobilisant la théorie de l’asymétrie identitaire. Une expérimentation au travers d’entretiens qualitatifs individuels a été menée auprès de 25 individus. Cette étude permet de dégager quatre stratégies identitaires individuelles. Une première stratégie consiste à défendre son identité de consommateur responsable quitte à mettre à distance une partie de son entourage. Une seconde stratégie relève de l’acceptation coupable du statut de consommateur non-responsable. Une troisième stratégie vise à nier l’existence de toute consommation responsable. Enfin, la dernière stratégie identifiée vise à rejeter finalement l’identité de consommateur responsable en rationnalisant ce choix au travers de l’existence d’obstacles externes. Ce faisant, cette étude participe d’une meilleure compréhension du consommateur responsable et de ses dynamiques internes.

Published: August 2018

Cet article analyse l’impact de la présence du fondateur et des descendants/héritiers sur la performance des entreprises familiales au Proche-Orient Méditerranéen. Sur un échantillon de 300 entreprises provenant de cinq États (Chypre, Egypte, Jordanie, Liban, Turquie), les résultats de cette étude vont partiellement à l’encontre de la théorie de l’agence. Nous avons trouvé que la taille du conseil a un impact positif sur les entreprises familiales dont le dirigeant n’est pas le fondateur. En revanche, ladite relation est négative et significative dans le cadre des entreprises familiales dirigées par leur fondateur. La présence d’administrateurs externes a un effet positif sur la performance des entreprises dirigées par le fondateur. Cependant, si l’entreprise est dirigée par les descendants, la présence d’administrateurs externes affecte négativement la performance. Bien que la fréquence des réunions du conseil ait un effet positif, cette corrélation est bien plus faible quand l’entreprise familiale est dirigée par son fondateur que lorsqu’elle l’est par les descendants. Finalement, la dualité du dirigeant améliore les performances si les dirigeants sont les descendants, mais n’a aucun effet sur l’entreprise dirigée par son fondateur.

Abstract
Cystic fibrosis (CF), one of the most common human genetic diseases worldwide, is caused by a defect in the CF transmembrane conductance regulator (CFTR). Patients with CF are highly susceptible to infections caused by opportunistic pathogens (including Burkholderia cenocepacia), which induce excessive lung inflammation and lead to the eventual loss of pulmonary function. Abundant neutrophil recruitment into the lung is a key characteristic of bacterial infections in CF patients. In response to infection, inflammatory neutrophils release reactive oxygen species and toxic proteins, leading to aggravated lung tissue damage in patients with CF. The present study shows a defect in reactive oxygen species production by mouse Cftr−/−, human F508del-CFTR, and CF neutrophils; this results in reduced antimicrobial activity against B. cenocepacia. Furthermore, dysregulated Ca2+ homeostasis led to increased intracellular concentrations of Ca2+ that correlated with significantly diminished NADPH oxidase response and impaired secretion of neutrophil extracellular traps in human CF neutrophils. Functionally deficient human CF neutrophils recovered their antimicrobial killing capacity following treatment with pharmacological inhibitors of Ca2+ channels and CFTR channel potentiators. Our findings suggest that regulation of neutrophil Ca2+ homeostasis (via CFTR potentiation or by the regulation of Ca2+ channels) can be used as a new therapeutic approach for reestablishing immune function in patients with CF.

Abstract
Cross-talk between NK cells and dendritic cells (DCs) is important in Th1 immune responses, including antitumor immunity and responses to infections. DCs also play a crucial role in polarizing Th2 immunity, but the impact of NK cell–DC interactions in this context remains unknown. In this study, we stimulated human monocyte-derived DCs in vitro with different pathogen-associated molecules: LPS or polyinosinic–polycytidylic acid, which polarize a Th1 response, or soluble egg Ag from the helminth worm Schistosoma mansoni, a potent Th2-inducing Ag. Th2-polarizing DCs were functionally distinguishable from Th1-polarizing DCs, and both showed distinct morphology and dynamics from immature DCs. We then assessed the outcome of autologous NK cells interacting with these differently stimulated DCs. Confocal microscopy showed polarization of the NK cell microtubule organizing center and accumulation of LFA-1 at contacts between NK cells and immature or Th2-polarizing DCs but not Th1-polarizing DCs, indicative of the assembly of an activating immune synapse. Autologous NK cells lysed immature DCs but not DCs treated with LPS or polyinosinic–polycytidylic acid as reported previously. In this study, we demonstrated that NK cells also degranulated in the presence of Th2-polarizing DCs. Moreover, time-lapse live-cell microscopy showed that DCs that had internalized fluorescently labeled soluble egg Ag were efficiently lysed. Ab blockade of NK cell–activating receptors NKp30 or DNAM-1 abrogated NK cell lysis of Th2-polarizing DCs. Thus, these data indicate a previously unrecognized role of NK cell cytotoxicity and NK cell–activating receptors NKp30 and DNAM-1 in restricting the pool of DCs involved in Th2 immune responses.
Oral squamous cell carcinoma masquerading as gingival overgrowth
Authors: Ramesh Roshni , Sadasivan Arun 
Published: August 2018

ABSTRACTGingival enlargements are frequently encountered in dental practice. There are different types of gingival enlargements and they vary according to the etiologic factors and pathologic processes that produce them. The exact diagnosis of the enlargement is important as some gingival enlargements can cause extensive morbidity or even mortality. Oral cancers especially squamous cell carcinomas present with variations in clinical presentation and the sites affected. A detailed medical history, clinical examination and radiographic evaluation will help identify the lesion. A biopsy will help provide a definitive diagnosis. An early diagnosis and treatment of squamous cell carcinomas is important as these tumours have a propensity for invasion of adjacent tissues and distant lymphatic metastasis which leads to a worsened prognosis. In this case report, the diagnosis and management of squamous cell carcinoma masquerading as a gingival overgrowth in the mandibular anterior region in a renal patient is reported. Dentists need to be aware and alert of the possibility of squamous cell carcinoma presenting on sites such as gingiva thereby preventing extensive morbidity and even mortality in these patients.

Authors: Camelo Sandra 
Published: August 2018

Abstract
This article embraces an expanded notion of ‘revitalisation’ that goes beyond linguistics and challenges colonial epistemic violence. It acknowledges the poetical, ethical, and political dimensions of indigenous languages practices and their deep articulation with the recreation of community filiations. Finally, it discusses how decolonial perspectives must not only expand the understandings of indigenous languages and revitalisation, but also stretch the limits of Academia and knowledge validity.

Published: August 2018

Organizational commitment has been a topic of extensive interest since 1950 due to its substantial implications on both employees and organizations. Therefore, it is crucial for every company to determine and understand the aspects which boost the commitment of its employees thus leading to achieve its objectives and optimize the human capital. Hence, the purpose of this research was to analyze the impact of core components of employee empowerment on the organizational commitment in the Lebanese Banking sector.This research adopted the principles of positivism where the researcher was independent from the study. Since the study was already grounded from an existing theoretical framework with the purpose of testing hypotheses, the deductive approach was followed. After studying the existing literature related to the subject, the researcher conducted a quantitative study. The data was distributed and collected from 123 employees working in the Lebanese Banking sector using a self-administered questionnaire. The aim of this questionnaire was to explore the influence of job autonomy, motivation, training and compensation on organizational commitment.The hypotheses which were proposed to be tested during the research were verified. The results reflected a positive relation between the components of employee empowerment and organizational commitment. This was in alignment with the other business sectors in Lebanon and in similar banking sector in the region and the West. Accordingly, the banks should consider employee empowerment as one of the factors in promoting organizational commitment. Consequently, this leads to employees’ organizational retention in the Lebanese Banking sector.

AbstractImproving light‐trapping capabilities through surface microstructuring of transparent conductive oxides is a promising approach to enhance solar cell efficiency. This study focuses on treating fluorine‐doped tin oxide (FTO) thin films using four‐beam direct laser interference patterning (DLIP) to create dot‐like periodic surface microstructures. The surface analysis using scanning electron microscopy and confocal microscopy reveals the presence of a periodic square grid of microcraters with a spatial period of ≈700 nm and an average depth ranging between 4 and 18 nm. These structures enhance the dispersion of incoming light up to 1000% in the visible and NIR spectra. When integrated into metal halide perovskite solar cells, FTO films patterned using low fluence conditions lead to a notable increase in the power conversion efficiencies (PCEs) compared to those made using untreated FTO. Importantly, preliminary stability tests on devices based on patterned FTO substrates show significantly improved stability compared to those fabricated using reference unpatterned substrates. These findings demonstrate that a DLIP treatment of FTO substrates is a promising technique that can substantially enhance the efficiency and stability of perovskite photovoltaic devices.

AbstractThe existence of the blood–brain barrier (BBB) and the characteristics of the immunosuppressive microenvironment in glioblastoma (GBM) present significant challenges for targeted GBM therapy. To address this, a biomimetic hybrid cell membrane‐modified dual‐driven heterojunction nanomotor (HM@MnO2‐AuNR‐SiO2) is proposed for targeted GBM treatment. These nanomotors are designed to bypass the BBB and target glioma regions by mimicking the surface characteristics of GBM and macrophage membranes. More importantly, the MnO2‐AuNR‐SiO2 heterojunction structure enables dual‐driven propulsion through near‐infrared‐II (NIR‐II) light and oxygen bubbles, allowing effective treatment at deep tumor sites. Meanwhile, the plasmonic AuNR‐MnO2 heterostructure facilitates the separation of electron–hole pairs and generates reactive oxygen species (ROS), inducing immunogenic tumor cell death under NIR‐II laser irradiation. Furthermore, MnO2 in the tumor microenvironment reacts to release Mn2+ ions, activating the cGAS‐STING pathway and enhancing antitumor immunity. In vitro and in vivo experiments demonstrate that these dual‐driven biomimetic nanomotors achieve active targeting and deep tumor infiltration, promoting M1 macrophage polarization, dendritic cell maturation, and effector T‐cell activation, thereby enhancing GBM catalysis and immunotherapy through ROS production and STING pathway activation.

Published: November 2024

AbstractLightweight, flexible, and thermostable thermally conductive materials are essential for enhancing heat dissipation efficiency in advanced electronics. The development of intrinsic thermally conductive polymers is the key to expanding the space for improving the thermal conductivity of polymer‐based thermal management materials. In order to balance the thermal conductivity and mechanical performance of bulk polymers, thermally conductive aramid nanofiber (ANF) films are assembled by manipulating the proton‐donating ability of solvents. Compared to water as a conventional proton donor, ethanol‐induced multi‐scale structures composed of dense hydrogen bonding interaction, large grain size, and uniform fiber topology endow the resulting ANF films with enhanced intrinsic thermal conductivity up to 5.05 W m−1 K−1 with a 34% increase, salient mechanical performance with the tensile strength of 181.4 MPa, and exceptional thermal stability higher than 500 °C. These outstanding properties of ANF films provide many possibilities for the preparation of polymer‐based thermally conductive materials.

AbstractThe interfacial electric field (IEF) between heterogeneous units plays an important role in the electronic modulation of active centers during oxygen evolution reaction (OER). However, the weak electronic coupling between spatially separated IEFs limits the deep activation of metal sites on the surface of the catalyst. Herein, a proof‐of‐concept strategy is provided that imbed MS2 (M = Ni3Fe) species with high spin Fe orbits into heterogeneous units to promote the electron penetrating between IEFs. By designing a Fe2O3@MS/MS2@MOy model catalyst, the electronic interaction between adjacent IEFs is effectively enhanced for the deep oxidation of bimetals on the surface, breaking the competing relationship between adsorbed evolution mechanism (AEM) and lattice oxygen mechanism (LOM) of catalysts during OER. As a result, the onset overpotential of the synthesized electrode is only 171 mV, and it maintains excellent stability for more than 2300 h at a current density of 10 mA cm−2 in 1 M KOH + 0.5 M NaCl electrolyte.

Published: November 2024

AbstractTraditional organic‐based chemiresistive sensors have been a key area of research due to their portability, low power consumption, low cost, turnability, and possibility for miniaturization. However, their real‐world applications have remained restricted by their low selectivity, low sensitivity, and low stability under demanding conditions, such as extreme temperature, humidity, and pH. As such, this review aims to lay the foundation for enhancing the performance of these gas sensors via chemical and physical modifications. To this end, an insight into the building blocks of chemiresistive gas sensors and the attributes of the main four gases (ammonia, carbon dioxide, hydrogen sulfide, and nitrogen dioxide) under aqueous conditions are provided. Such features ultimately determine the enhancement strategy that is best suited to improve the chemiresistive gas sensors performance. Furthermore, this article provides an outlook into the current bottleneck in sensor development and its translation from lab to end‐consumer use. Overall, this review aims to serve as a roadmap for developing next‐generation, high performing chemiresistive gas sensors.

AbstractDesigning excellent anode materials to enhance the sluggish interfacial kinetics of Na+ is a key challenge in improving the electrochemical performance of sodium‐ion batteries (SIBs). Herein, an ultra‐thin fast‐ionic conductor NaB5C coating TiB2 nanoflowers with vertically aligned nanosheet arrays to form yolk–shell TiB2@NaB5C (TBNBC) nanospheres as an anode material for SIBs. The unique structure creates direct and short ion/electron transfer pathways and reserves enough space to prevent the uneven electrochemical reactions from TiB2 nanosheets aggregation and stacking, thus ensuring the long‐term cycling stability of SIBs. Additionally, the NaB5C coating with fast‐ionic conductor functional interphase provides rapid Na+ transport channels and effectively reduces the Na+ de‐solvation barrier, accelerating Na+ reaction kinetics. Furthermore, a homogeneous and robust solid electrolyte interphase (SEI) film including inorganic boron species and fluorine‐rich inner layer is constructed on the TBNBC electrode to delocalize stress and induce a uniform Na+ flux, further promoting fast Na+ interphase reaction kinetics. Consequently, the optimized composites achieve ultrastable cycling performances of 173 mAh g−1 over 5000 cycles at 10 A g−1. More importantly, they also exhibit an outstanding capacity of 182.2 mAh g−1 at −20 °C. This work offers opportunities for the energy storage use of transition metal borides under extreme conditions.
