Les transformations de l’assurance maladie complémentaire à la lumière de la démutualisation/hybridation des banques coopératives
Authors: Abecassis Philippe , Coutinet Nathalie , Domin Jean-Paul 
Published: July 2018

Ce travail analyse l’évolution de deux secteurs comparables : les banques mutualistes et coopératives (M&C) d’une part, les mutuelles de santé et les institutions de prévoyance d’autre part. Si les premières ont entamé une phase de concentration du capital et de démutualisation/hybridation dès les années 1980, les secondes connaissent aujourd’hui une évolution semblable, mais plus prudente. L’article propose dans un premier temps une analyse comparative des deux secteurs et montre dans une seconde partie que les processus d’hybridation constatés dans le secteur bancaire ne sont pas identiques dans l’assurance maladie complémentaire. Les processus de démutualisation/hybridation n’ont pas été sans conséquence sur le fonctionnement des banques M&C, mais il semble que les mutuelles de santé et les institutions de prévoyance protègent mieux leurs principes mutualistes originels.
Les réseaux d’innovation public-privé dans les services (RIPPS) : une nouvelle expression des réseaux d’innovation dans une économie des services et du développement durable
Authors: Djellal Faridah , Gallouj Faïz 
Published: July 2018

Le concept de réseau d’innovation est un concept bien établi qui a fait l’objet d’une abondante littérature. Nous nous intéressons dans ce travail à des réseaux d’innovations particuliers, encore peu connus, mais qui se développent dans une économie de service dominante : les réseaux d’innovation public-privé dans les services (RIPPS). Les RIPPS décrivent des collaborations entre organisations de services publiques et privées dans le domaine de l’innovation. Ils diffèrent des RI traditionnels de plusieurs manières. Tout d’abord, les prestataires de services y sont les acteurs principaux. Ensuite, les relations entre les acteurs publics et privés sont placées au centre de l’analyse. Enfin, l’innovation non technologique, souvent négligée dans la littérature, y est prise en compte. L’objet de ce travail est, tout d’abord, d’examiner la manière dont les caractéristiques des RIPPS peuvent contribuer à modifier et enrichir le concept traditionnel de RI, et ensuite, d’en tirer d’éventuels enseignements en matière de politique publique. Ce travail s’appuie à la fois sur un bilan de la littérature et sur l’exploitation d’une base de données d’études de cas de RIPPS constituée dans le cadre du projet européen ServPPIN (Public Private Innovation Networks in Services).
Cumulativité et diversification des exportations dans le bas et le haut de gamme : une vérification empirique
Authors: El Gouddi Sami 
Published: July 2018

Notre problématique concerne l’étude de l’aspect cumulatif et la diversification des exportations des pays. Nous tentons de comprendre si la relation entre l’aspect cumulatif et la diversification est stable ou si au contraire elle est, d’une façon ou d’une autre, affectée par la dimension cognitive des pays et des produits. Afin d’apporter des éléments de réponse à ces interrogations, nous menons des estimations économétriques sur des pays à niveaux de développement différents tout en mettant l’accent sur le rôle de la composante cognitive des produits sur la base d’une différenciation qualitative. Ainsi, à travers cette étude empirique, nous chercherons à répondre à trois types de questions. Tout d’abord, dans quelle mesure la spécialisation dans les différentes gammes de qualité peut-elle s’avérer cumulative. La relation entre l’aspect cumulatif et la diversification est-elle vraiment antagoniste, comme le montrent la plupart des modèles théoriques ? Enfin, la différenciation verticale conforte-t-elle les faits statistiques stylisés affirmant l’existence d’une relation positive entre la taille d’un pays et son degré de diversification ? Au-delà des résultats mis en évidence, ce papier ouvre de nouvelles pistes de recherche, notamment en ce qui concerne l’implication des externalités de connaissances dans l’évolution des avantages comparatifs.
Service quality perceptions of campus-based food outlets
Authors: Eresia-Eke Chukuakadibia E. , Stephanou Mon A. , Swanepoel Rochelle 
Published: July 2018

Orientation: In a competitive retail business environment, the essence of service quality is invariably amplified. Within a university context, the same applies, given that the student population of customers is relatively finite and yet there are a variety of food outlets on campuses.Research purpose: This study aims to investigate the existence (or lack of it) of a relationship between gender, race and price and the dependent variable of students’ service quality perception of campus-based food outlets. Although gender and race are the most obvious defining demographic features of a student population, the variable of price is usually a major consideration for student purchases.Motivation for the study: The study is an applied research as it is focused on addressing an issue with real-life business implications.Research design, approach and method: It employs the use of data collected in a cross-sectional manner from 200 respondents selected through non-probability sampling.Main findings: The findings of the study indicate that no significant differences exist in service quality perception when gender is considered. Conversely, results show that the service quality perceptions of racial groups differ. The study also finds that a weak but positive correlation exists between price and service quality perceptions.Practical/managerial implications: These results indicate practical implications as they can become useful condiments for refining the offerings and services of the studied campus-based food outlets in the quest to meet or exceed customer expectations.Contribution/value-add: From an academic perspective, the study builds on existing knowledge by exposing the association that the independent variables of gender, race and price have with students’ service quality perception in the specific context of campus-based food outlets in Gauteng, South Africa.
Chief executive officer compensation sensitivity in the South African mining industry
Authors: Bussin Mark 
Published: July 2018

Orientation: The level of chief executive officer (CEO) compensation and its relationship with organisational performance has generated considerable interest worldwide. In light of compromised mining productivity as a result of the recent labour unrest in South Africa, some commentators have questioned the justification of certain CEO compensation in the country’s mining industry.Research purpose: The primary purpose of this study was to describe the relationship between CEO compensation and organisational performance in the South African mining industry.Motivation for the study: A deeper understanding of the relationship would enhance knowledge when developing optimal CEO reward systems to ensure sustainability of the mining industry within the South African context.Research design, approach and method: The research was a quantitative, archival study involving 30 mining companies over a 5-year period. The statistical analysis techniques used in the study included analysis of normality variance and multivariate regression.Main findings: The main finding of the research was that there was a moderate to strong relationship between CEO compensation and organisational performance in the South African mining industry. However, operating expenses have progressively increased, putting performance under pressure. Furthermore, it was also found that organisation size plays an influential role in CEO compensation levels.Practical/managerial implications: While the CEO compensation appears to be generally aligned with the organisational performance, the findings suggest that boards of directors should focus on structuring reward systems more optimally to mitigate managerial rent seeking in large companies and unsustainability in smaller companies.Contribution/value-add: This study has contributed to the body of existing knowledge on executive pay for performance in the context of the South African mining industry. In addition, the study has demonstrated that the other measures related to non-performance need to be considered in executive compensation design. The study adds practical value in contributing to information for engagements with stakeholders such as organised labour on executive pay.
‘Flowing’ under the radar in a multifaceted liquid reality: The ekerk narrative
Authors: Joubert Stephan 
Published: July 2018

We live in a liquid new world driven by incessant change. Our reality is constantly shaped by new forms of non-linear individualism, which is expressed in countless factions, networks, tribes and alliances. Social systems do not maintain their shape for very long, because they decompose and melt faster than the time it takes to cast them, according to the sociologist Zygmunt Bauman. Religious institutions that do not come to terms with these rapid rates of change soon find themselves trapped in a so-called parallel universe, with hardly any influence on society. In order to embrace our fluid new reality with its numerous open systems and ever-increasing levels of complexity, ekerk understands herself as a movement of Jesus followers whose tribal identity is shaped around his teachings on the Kingdom of God, and which is reflected in the values of relationality and generosity. We have ‘tribal habitats’ in various digital and physical spaces. Under the radar of institutionalised church and academia, but also as their ally in a somewhat subversive manner, ekerk facilitates the spreading of the good news of Jesus in decentralised but very real ways. ekerkalso runs a large generosity ministry, as well as various seminars, meetings and growth programmes such as DieGang/TheGang to invest in young Christian leaders.
High incidence of cisplatin-induced ototoxicity in paediatric patients in the Western Cape, South Africa
Authors: Phanguphangu Mukovhe , Ramma Lebogang 
Published: July 2018

Background: Fourteen million new cancer cases are reported annually, and up to 10% of those involve children below 15 years. Cisplatin, a commonly used anti-cancer drug for its high success rate, is associated with ototoxicity. Cisplatin-induced ototoxicity is characterised by permanent bilateral severe-to-profound hearing loss. Hearing loss, when occurring during childhood, can impact negatively communication development, scholastic performance and quality of life.Aim: To determine the incidence of cisplatin-induced ototoxicity in paediatric oncology.Setting: A retrospective records review of paediatric oncology patients who underwent cisplatin-based chemotherapy and had ototoxicity monitoring from January 2015 to December 2017 at a children’s hospital.Method: Data collected included demographic, cisplatin treatment and audiometric information. The data were analysed using descriptive and inferential statistics.Results: A total of 49 records meeting the inclusion criteria were reviewed. Ototoxic hearing loss was found in 39 (80%) of the patients whose records were reviewed and the majority (56%) presented with a bilateral moderate-to-severe sensorineural hearing loss. Distortion product otoacoustic emissions were absent in 32 (67%) patients. Cumulative dose (> 200 mg/m2) was associated with higher incidences of ototoxicity (odds ratio [OR]: 1.81; 95% confidence interval [CI]: 0.67–17.34; p = 0.044). Younger patients (< 10 years) had higher odds of developing ototoxicity, but this was not statistically significant (OR: 4.00; 95% CI: 0.82–19.46; p = 0.085).Conclusion: This study found a high incidence of cisplatin-induced ototoxicity in paediatric oncology patients. This is concerning because hearing loss during this age can have long-term negative impact on a child’s development and overall quality of life. Early identification of ototoxicity-induced hearing loss and appropriate intervention are highly recommended in this patient group.

Ruimtelijk beleid voor de energietransitie: centraal wat moet? Een studie naar het omgevingsrechtelijk overheidsinstrumentarium in de energietransitie
In deze bijdrage onderzoeken auteurs de connectie tussen energietransitie en het omgevingsrecht. Hierbij staat de vraag centraal hoe de keuze voor groot- of kleinschalige maatregelen het omgevingsrechtelijk kader en de ruimte voor een lokale ruimtelijke afweging kan beïnvloeden. Daarbij worden twee transitiepaden nader bekeken: windenergie op land (als onderdeel van het verduurzamen van de elektriciteitsproductie) en de verduurzaming van ruimteverwarming en warm tapwater in de gebouwde omgeving.

Abstract
Background: The Scutellaria barbata – Hedyotis diffusa herb pair has appeared in classical prescriptions and has usually been used for the treatment of cancer and inflammatory conditions. Objective: For quality control of this herb pair, a rapid and reliable HPLC-quadrupole-time-of-flight(Q-TOF)-MS method was used for the simultaneous determination of alpinetin, apigenin-7-O-β-D-glucopyranoside, scutellarein, apigenin, quercetin-3-O-β-D-glucopyranoside, wogonoside, quercetin, amentoflavone, wogonin, chrysin, luteolin, rutin, naringenin, baicalein, and baicalin in the S. barbata–H. diffusa herb pair. Methods: LC-MS analysis was performed on a Shimadzu HPLC 20ADXR LC system in-line with an AB-SCIEX 5600 Triple TOF mass spectrometer. Results: The calibration curves showed good linearity in a relatively wide concentration range (r &gt;0.996). The LOD and LOQ were less than 20 and 68 ng/mL, respectively. The relative standard deviation (RSD) values of intraday and inter-day precision were &lt;3.31% for all the analytes. The recoveries of the method were in the range of 94.6–106.0%, with RSD &lt;4.72%. The RSD values of peak areas in the stability study were not more than 4.28% for all analytes within 2 days. These results revealed that the method exhibited good sensitivity, precision, accuracy, and stability. Conclusions: This method could be applied to the quantitative determination of 15 flavonoids in the S. barbata – H. diffusa herb pair. Highlights: (1) The established method of HPLC-Q-TOF-MS is simple, fast, sensitive, and reliable. (2) 15 Flavonoids in the S. barbata–H. diffusa herb pair were simultaneous determined.
Self‐Protective Room‐Temperature Phosphorescence of Fluorine and Nitrogen Codoped Carbon Dots

Published: July 2018

AbstractThe unstable triplet excited state is a core problem when developing self‐protective room temperature phosphorescence (RTP) in carbon dots (CDs). Here, fluorine and nitrogen codoped carbon dots (FNCDs) with long‐lived triplet excited states, emitting pH‐stabilized blue fluorescence and pH‐responsive green self‐protective RTP, are reported for the first time. The self‐protective RTP of FNCDs arises from n–π * electron transitions for CN/CN bonds with a small energy gap between singlet and triplet states at room temperature. Moreover, the interdot/intradot hydrogen bonds and steric protection of CF bonds reduce quenching of RTP by oxygen at room temperature. The RTP emission of FNCDs shows outstanding reversibility, while the blue fluorescence emission has good pH stability. Based on these FNCDs, a data encoding/reading strategy for advanced anticounterfeiting is proposed via time‐resolved luminescence imaging techniques, as well as steganography of complex patterns.

AbstractPorous CoNC catalysts with ultrahigh surface area are highly required for catalytic reactions. Here, a scale‐up method to synthesize gram‐quantities of isolated Co single‐site catalysts anchored on N‐doped porous carbon nanobelt (Co‐ISA/CNB) by pyrolysis of biomass‐derived chitosan is reported. The usage of ZnCl2 and CoCl2 salts as effective activation–graphitization agents can introduce a porous belt‐like nanostructure with ultrahigh specific surface area (2513 m2 g−1) and high graphitization degree. Spherical aberration correction electron microscopy and X‐ray absorption fine structure analysis reveal that Co species are present as isolated single sites and stabilized by nitrogen in CoN4 structure. All these characters make Co‐ISA/CNB an efficient catalyst for selective oxidation of aromatic alkanes at room temperature. For oxidation of ethylbenzene, the Co‐ISA/CNB catalysts yield a conversion up to 98% with 99% selectivity, while Co nanoparticles are inert. Density functional theory calculations reveal that the generated CoO centers on isolated Co single sites are responsible for the excellent catalytic efficiency.
Programmable 3D Shape Changes in Liquid Crystal Polymer Networks of Uniaxial Orientation

Published: July 2018

Abstract3D programmable materials are highly interesting and have a great potential to enable smart robotic devices. Stimuli‐responsive liquid crystal polymer networks (LCNs) offer an attractive platform for the design and fabrication of 3D programmable materials. To date, extensive efforts have been devoted to the design of 3D programmable LCNs by spatially modulating the orientation of liquid crystals. However, the practical application of LCN actuators has been elusive, partly due to tedious orientation technology and monotonous geometry. To resolve this issue, programmable 3D shape changes achieved in LCNs with uniaxial orientation and homogenous composition using a mechanical programming process inspired by the “programming process” of shape‐memory polymers are reported. The mechanical programming process is suitable for LCNs with distinct geometries, for example, the film and fiber, suggesting a promising way for the design of 3D programmable LCN actuators with complex geometries, and deformation profiles (buckle, helix, horn).
Binder‐Free Nanoparticulate Coating of a Polyethylene Separator via a Reactive Atmospheric Pressure Plasma for Lithium‐Ion Batteries with Improved Performances

Published: July 2018

AbstractA reactive atmospheric pressure plasma containing Ar/O2/hexamethyldisiloxane is applied to coat polyethylene (PE) separators for lithium‐ion batteries. The PE separator moves through the plasma region roll‐to‐roll, and its top and internal fiber surface is coated with a thin SiOxCyHz film composed of nanoparticulates with an average size of ≈100 nm. The nanoparticulate film has relatively high heat resistance, which provides a PE separator capable of structural support with improved thermal stability. Meanwhile, the polar functional groups on the PE surface improve its crucial properties such as wettability, electrolyte uptake, and ionic conductivity. A mere 3 min of coating endows the lithium‐ion battery with a lower interface resistance and improved C‐rate and cycling performances. Most importantly, the binder‐free coating method provides a new, eco‐efficient way to improve the performances of polyolefin separators for lithium‐ion batteries.

Published: July 2018

AbstractKinds of interfacial engineering technologies are explored in perovskite solar cells (PSCs), which are proved to be benefit for the devices to achieve higher efficiency, less hysteresis, and/or better stability. In this work, in an inverted p–i–n structured PSC, a monolayer of 5‐aminovaleric acid (5‐AVA) molecules with bifunctional groups is introduced to modify the surface of p‐NiMgLiO compact hole transport layer (HTL). This key surface modification is not only improving the resultant perovskite film's quality, but also facilitating efficient charge extraction at the HTL/perovskite interface, which result in improved power conversion efficiency (PCE) from 18.0 to 19.4%. Furthermore, the 5‐AVA‐modified device can withstand much higher poling bias (>1.8 V) for a longer time than the pristine one, showing little nonsteady state current and excellent consistency of forward and reverse photocurrent–voltage curves after high bias poling. Benefitting from the exceptionally stable interface, the 5‐AVA‐modified device shows much improved long‐term stability, which can maintain over 90% of its initial PCE after 300 h continuous light soaking at maximum power point tracking condition.
Actuating Textiles: Next Generation of Smart Textiles

Published: July 2018

AbstractSmart textiles have been around for some decades. Even if interactivity is central to most definitions, the emphasis so far has been on the stimuli/input side, comparatively little has been reported on the responsive/output part. This study discusses the actuating, mechanical, output side in what could be called a second generation of smart textiles—this in contrast to a first generation of smart textiles devoted to sensorics. This mini review looks at recent progress within the area of soft actuators and what from there that is of relevance for smart textiles. It is found that typically still forces exerted are small, so are strains for many of the actuators types (such as electroactive polymers) that could be considered for textile integration. On the other side, it is argued that for many classes of soft actuators—and, in the extension, soft robotics—textiles could play an important role. The potential of weaving for stress and knitting for strain amplification is shown. Textile processing enables effective production, as is analyzed. Textile systems are made showing automatic actuation asked for in stand‐alone solutions. It is envisioned that soft exoskeletons could be an achievable goal for this second generation of smart textiles.
Progress on Black Phosphorus Photonics

Published: July 2018

AbstractRecent years have witnessed the rapidly growing interests in the rediscovered black phosphorus (BP), an elemental group‐V layered material with very high carrier mobility among all semiconducting layered materials. As a layered semiconductor, the bandgap of intrinsic BP varies from ≈0.3 to 2 eV depending on the thickness. This bandgap value can be tuned to below 50 meV by a moderate external electric field. Adsorption doping and external pressure can also effectively modify its bandgap. The largely tunable bandgap of BP makes it a promising material for infrared optics. Moreover, its unique puckered structure leads to the anisotropic in‐plane properties, making it ideal for the exploration of exotic physical phenomena and the realization of novel devices. Here, the fundamental optical properties are reviewed and latest developments on BP photonic and optoelectronic devices are discussed.
