Influence of Cold Rolling Process on Mini Spangle Formation of 55%Al-Zn Alloy Coating Steel Sheet
Authors: Guo Tai Xiong , Dong Xue Qiang , Ran Chang Rong
Published: October 2018

According to that mini spangle is the most common defect affecting the appearance quality of hot-dip 55%Al-Zn alloy coated steel sheet, industrial experiments and statistical analysis were done to investigate the influence of cold rolling process on the formation of mini spangle. The results show that, with the decrease of rolling oil concentration, the increase of rolling time, and the increase of rolling pass, the probability of mini-spangle formation increases. Due to the different equipment conditions, the probability of mini-spangle formation on the upper and lower surfaces of steel strip is different. The reason of mini-spangle formation lies in the presence of carboxylates (R-COO-Fe) result from the residual emulsion on the surface of cold rolled steel strip. The carboxylates may interfere with the interfacial reaction between the steel substrate and Al-Zn bath, and result in more convex Fe5Si2Al20 phases formed on the surface of intermetallic compound layer. The Fe5Si2Al20 phases may provide more heterogeneous nucleation sites for the formation of Al-rich dendrites and lead to the formation of mini spangle.

Authors: Khunphet Apichaya , Janudom Somjai , Mahathaninwong Narissara
Published: October 2018

This work investigated the effects of sealing agents on properties of 7075 slurry cast substrate anodized in 1M sulfuric acid solution. The sealing agents tested were hot water, potassium dichromate, teflon, and nickel fluoride. It was found that anodized 7075 slurry cast Al oxide film sealed with teflon gave the highest hardness and the best corrosion resistance. It is possible that the porous oxide film was plugged by teflon, reducing porosity more than hot water, potassium dichromate, or nickel fluoride sealing.

Published: October 2018

The self-organization of COOH-functionalized multiwall carbon nanotubes (MWCNTs) during droplet evaporation of their aqueous suspension in a constant uniform electric field (E) was investigated. It was established that the COOH-functionalization polarizes the MWCNTs in the transverse direction to their axis. Depending on their size, MWCNTs tended to agglomerate into three different stable structures in different drop regions. There were linear, fractal and cluster structures (LS, FS, and CS). Sizes of the FSs decreased as 1/Е, whereas the rate of their growth increased as Е2. The single-walled carbon nanotubes (SWCNTs) were found inside the LSs and CSs. The chiral indices of the SWCNTs were determined, corresponding to metallic and semiconducting conductivities. An analysis showed that as a result of coagulation and amassment of the carbon nanotubes (CNTs) near electrodes, there were formed conductive regions. When the concentration of MWCNTs reached some value in part nearest to an electrode, this part became conductive. The positive and negative electrodes, formed now by MWCNTs, shifted towards each other. The observed effects show that considered self-organization is controllable by the electric field.

Published: October 2018

Bioactive compounds such as essential oils (EO), botanical extracts and natural resins are well known to have beneficial properties. Among these properties are their antibacterial activity. A disadvantage of these compounds is that they are volatile. Therefore, encapsulation is a good way to overcome this problem. In this study, the morphology, particle size distribution, Zeta potential and microbiological activity of chitosan nanoparticles incorporated with three different bioactive compounds having antimicrobial properties: ethanol extract of propolis, thyme essential oil and ethanol extract of Byrsonima crassifolia (L.) Kunth were evaluated. Nanoparticles were synthesized using the nanoprecipitation method. The morphology was observed using transmission electron microscopy (TEM). Also, particle size distribution and Zeta potential were measured. Results show spherical in shape nanoparticles. Thyme essential oil-loaded chitosan nanoparticles (TEO-CSNPs) showed the smallest particle size and highest stability as assessed by Zeta potential measurement, followed in stability by ethanol extract of propolis-loaded chitosan nanoparticles (EEP-CSNPs), ethanol extract of Byrsonima crassifolia (L.) Kunth (EEBC-CSNPs) and finally by chitosan nanoparticles (CSNPs). The antibacterial activity of the bioactive compounds-loaded chitosan nanoparticles was evaluated against Staphylococcus aureus. The highest antibacterial activity was observed for TEO-CSNPs with an inhibition halo (IH) value of 10.54±0.78 mm, followed by EEP-CSNPs (8.10±1.19 mm). EEBC-CSNPs and CSNPs did not show zone of inhibition. Bioactive compounds-loaded chitosan nanoparticles represents a good alternative for bacterial control of food borne pathogens in applications for fruits and vegetables conservation.

Published: October 2018

This work presents the synthesis and characterization of mixed rare earths hydroxide heterogeneous catalyst. The catalysts were prepared by co-precipitation of mixed rare earths with NaOH at different pH (6, 7 and 12). The prepared catalysts were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM–EDS). The XRF results showed that the catalyst composed of cerium (Ce), neodymium (Nd), lanthanum (La), praseodymium (Pr) and samarium (Sm) being predominant at pH up to 7. Particularly, cerium (Ce) was favorable precipitation at pH 7. This results were confirm by SEM-EDS. The Ce (OH)3 phase was clearly observed for the mixed rare earth catalyst precipitated at pH 7. The XRF, SEM-EDS and XRD results were consistency.

Published: October 2018

In this paper, we report the preparation of 1-methylimidazolium acetate (MIMOAc) through solvent-free sonochemical synthesis and its characterization using1H-NMR,13C-NMR and FTIR-ATR spectroscopy. Its effects on the morphological, structural and electrochemical properties of electrospun polyacrylonitrile (PAN) fibers were also investigated. SEM and AFM results showed that the MIMOAc-doped PAN fibers produced are thinner than that of the pristine PAN hence allowing more surface area for ion mobility. Its electrochemical performance compared well to the obtained results in preference to the conventional 1M KOH(aq)as aqueous electrolyte. The fabrication of a novel supercapacitor prototype following an electrical double-layer capacitor configuration assembled by mechanically pressing the electrospun MIMOAc/PAN nanofiber membranes between two activated carbon/graphene oxide (GO) composite electrodes on ITO-coated glass current collectors was presented in detail.

Published: October 2018

Connexin 43 (Cx43) deficiency was found to increase mortality in a mouse model of bacterial peritonitis, and Cx43 is upregulated in macrophages by LPS treatment. In this study, we characterized a novel signaling pathway for LPS-induced Cx43 expression in RAW264.7 cells and thioglycolate-elicited peritoneal macrophages (TGEMs). LPS alone or LPS-containing conditioned medium (CM) upregulated Cx43. Overexpression or silencing of Cx43 led to the enhancement or inhibition, respectively, of CM-induced TGEM migration. This response involved the inducible NO synthase (iNOS)/focal adhesion kinase (FAK)/Src pathways. Moreover, CM-induced migration was compromised in TGEMs from Cx43+/− mice compared with TGEMs from Cx43+/+ littermates. Cx43 was upregulated by a serum/glucocorticoid-regulated kinase 1 (SGK) activator and downregulated, along with inhibition of CM-induced TGEM migration, by knockdown of the SGK gene or blockade of the SGK pathway. LPS-induced SGK activation was abrogated by Torin2, whereas LPS-induced Cx43 was downregulated by both Torin2 and rapamycin. Analysis of the effects of FK506 and methylprednisolone, common immunosuppressive agents following organ transplantation, suggested a link between these immunosuppressive drugs and impaired macrophage migration via the Cx43/iNOS/Src/FAK pathway. In a model of Escherichia coli infectious peritonitis, GSK650349-, an SGK inhibitor, or Torin2-treated mice showed less accumulation of F4/80+CD11b+ macrophages in the peritoneal cavity, with a delay in the elimination of bacteria. Furthermore, following pretreatment with Gap19, a selective Cx43 hemichannel blocker, the survival of model mice was significantly reduced. Taken together, our study suggested that Cx43 in macrophages was associated with macrophage migration, an important immune process in host defense to infection.
Understanding power struggles in the Pentecostal church government
Authors: Matshobane Mangaliso , Masango Maake J.
Published: October 2018

This article highlights the power struggles that the Pentecostal church experiences in its church governance. These power struggles become very contentious to a point where members take each other to legal courts, which ends in multiple schisms that tarnish the image of the Pentecostal movement. Most literature on church conflicts approach power struggles as caused by personality disorders. This article seeks to highlight a different approach where power struggles are more a result of structural factors than personal ones emanating from a hybrid nature of polity in the Pentecostal church and other structural factors of conflict like finances, education and leadership. Finally, an educational pastoral care methodology is proposed for this article.

Effect of salt seed particle surface area, composition and phase on secondary organic aerosol mass yields in oxidation flow reactors

Published: October 2018

Abstract. Atmospheric particulate water is ubiquitous, affecting particle transport and uptake of gases. Yet, research on the effect of water on secondary organic aerosol (SOA) mass yields is not consistent. In this study the SOA mass yields of an α-pinene and m-xylene mixture, at a concentration of 60 μg m−3, was examined using an oxidation flow reactor operated at an atmospherically relevant RH of 60 % and a residence time of 160 s. Wet or dried ammonium sulphate and ammonium nitrate seed particles were used. By varying the amount of seed particle surface area, the underestimation of SOA formation induced by the short residence time in flow reactors was confirmed. Starting at a SOA mass concentration of ~ 5 μg m−3, the maximum yield increased a factor ~ 2 with dry seed particles, and on average a factor 3.2 with wet seed particles. Hence, wet particles increased the SOA mass yield by ~ 60 % compared to the dry experiment. Maximum yield in the reactor was achieved using a surface area concentration of ~ 1600 μm2 cm−3. This corresponded to a condensational lifetime of 20 s for low volatile organics. The O : C ratio of SOA on wet ammonium sulphate was significantly higher than when using ammonium nitrate or dry ammonium sulphate seed particles, probably due to differences in heterogeneous chemistry.
Retrospective analysis of 2015–2017 winter-time PM2.5 in China: response to emission regulations and the role of meteorology
Authors: Chen Dan , Liu Zhiquan , Ban Junmei , Zhao Pusheng , Chen Min
Published: October 2018

Abstract. To better characterize the anthropogenic emission relevant aerosol species, the GSI-WRF/Chem data assimilation system was updated from the GOCART aerosol scheme to MOSAIC-4BIN scheme. Three year (2015–2017) winter-time (January) surface PM2.5 observations from 1600+ sites were assimilated hourly using the updated 3DVAR system in the assimilation experiment CONC_DA. Parallel control experiment that did not employ DA (NO_DA) was also performed. Both experiments were verified against the surface PM2.5 observations, MODIS 550-nm AOD and also 550-nm AOD at 9 AERONET sites. In the NO_DA experiment using 2010_MEIC emissions, modeled PM2.5 are severely overestimated in Sichuan Basin (SB), Central China (CC), YRD (Yangzi River Delta), and PRD (Pearl River Delta) which indicated the emissions for 2010 are not appropriate for 2015–2017, as strict emission control strategies were implemented in recent years. Meanwhile, underestimations in Northeastern China (NEC) and Xin Jiang (XJ) were also observed. The assimilation experiments significantly reduced the high biases of surface PM2.5 in SB, CC, YRD, and PRD, and also low biases in NEC. However the improvement of the low biases in XJ is relatively small due to the large difference between the observations and the model background in the DA process, likely indicating that the emissions in the model are seriously underestimated in this region. Assimilating surface PM2.5 also significantly changed the column AOD and resulted in closer agreement with MODIS data and observations at AERONET sites. The observations and the reanalysis data from assimilation experiment were used to investigate the year-to-year changes. As the differences of the reanalysis data (CONC_DA) among years reflect combining effects of meteorology and emission and the differences of modeling result from control experiment (NO_DA, with same emissions) among years reflect the separate effect of meteorology, the important roles of emission and meteorology in driving the changes in the three years can be distinguished and analyzed quantitatively. The analysis indicated that meteorology played different roles in 2016 and 2017: the higher pressure system, lower temperature and higher PBLH in 2016 are favorable for pollution dispersion (compared with 2015) while the situation is almost the opposite in 2017 (compared with 2016) that leads to the increasing PM2.5 from 2016 to 2017 although emission control strategy were implemented in both years. There are still large uncertainties in this approach especially the inaccurate emission input in the model brings large biases in the analysis.

Published: October 2018

Abstract. We quantify the snowmelt-albedo feedback at Neumayer Station, East Antarctica, using 24 years (1992–2016) of high-quality meteorological observations to force a surface energy balance model. The modelled 24-year cumulative surface melt at Neumayer amounts to 1060 mm water equivalent (w.e.), with only a small uncertainty (± 3 mm w.e.) from random measurement errors. Results are more sensitive to the chosen value for the surface momentum roughness length and fresh snow density, yielding a range of 800–1140 mm w.e. Melt at Neumayer occurs only in the months November to February, with a summer average of 46 mm w.e. and large interannual variability (σ = 40 mm w.e.). Absorbed shortwave radiation is the dominant driver of temporal melt variability at Neumayer. To assess the importance of the melt-albedo feedback we include and calibrate an albedo parameterisation in the surface energy balance model. We show that, without the snowmelt- albedo feedback, surface melt at Neumayer would be approximately three times weaker, demonstrating how important it is to correctly represent this feedback in model simulations of surface melt.

ObjectiveDuplication of effort across development projects is often the resultant effect of poor donor coordination in low and middle income countries which receive development assistance. This paper examines the persistence of duplication through a case study of health facility listing exercises in Nigeria.MethodsDocument reviews, key informant interviews and a stakeholder’s meeting were undertaken to identify similar health facility listing exercises between 2010 and 2016.ResultsAs an outcome of this process, ten different health facility listing efforts were identified.Discussions Proper coordination and collaboration could have resulted in a single list grown over time, ensuring return on investments. This study provides evidence of the persistence of duplication, years after global commitment to harmonization, better coordination and efficient use of development assistance were agreed to.ConclusionsThe paper concludes by making a proposal for strategic leadership in the health sector and the need to leverage information and communications technology through the development of an electronic Health Facility Registry that can archive the data on health facilities, create opportunity for continuous updates of the list and provide for easy sharing of the data across different country stakeholders thereby eliminating duplication.
Opening doors: A thematic analysis of the long-term impact of community-based research in the field of HIV
Authors: Caine Vera , Mill Judy , Chaw-Kant Jean , McGinn Maggie , Chorney Ray
Published: October 2018

Health professionals, including nurses, have been identified as a source of stigma for persons living with HIV (PLWH). Stigma towards PLWH may be predicated on the lack of basic education about HIV in pre-licensure nursing curricular, few opportunities for continuing education in HIV, and persistent discriminatory attitudes about HIV among nurses. From 2011 to 2013, in collaboration with the Canadian Association for Nurses in AIDS Care (CANAC), we developed and implemented a community-based intervention research project entitled A clinical mentorship model for Canadian nurses in HIV care. In previous publications, we reflected on the process, strengths and challenges of conducting this community-based research (CBR) study and we documented the improved knowledge, attitudes, and practices of nurses. Five years after the completion of our CBR study, we re-engaged with some of the participants, with the purpose of assessing whether outcomes had been sustained. We interviewed 15 of the original 56 participants. The data analysis was carried out using thematic analysis. In the current paper we highlight the themes of project design, in particular the CBR design, capacity building and relationships that emerged in our follow-up study. Overall participants looked back on their involvement in the mentorship project as a very positive experience that had opened new, unexpected doors. The participants described many areas of personal and professional growth as a result of their participation. Despite a period of more than five years since the completion of the initial CBR study, the community-based participatory design, the inclusion of PLWH as mentors, and the focus on experiential learning, were seen as fundamental to sustaining the long-term positive impact.
Inclusive Higher Education for Students with Disabilities in China: What Do the University Teachers Think?
Authors: Zhang Yuexin , Rosen Sandra , Cheng Li , Li Jingshan
Published: October 2018

Inclusive higher education is a path to protect the educational rights of university students with disabilities. University teachers’ attitudes toward students with disabilities, and towards their inclusion in universities, are a key factor that will affect the development of inclusive higher education. This study used a questionnaire to explore an overall perspective of how university teachers in China view inclusive higher education from emotional, cognitional and conative aspects. Their responses suggest that university teachers in China have positive emotion and cognition toward the rights of students with disabilities to receive higher education; the teachers do, however, appear to lack motivation, relevant knowledge, skills, and effective strategies to cope with the students’ special needs. This suggests that effective implementation of inclusive higher education must be supported by an effective service center for those who have disabilities, a support network of professionals, and an administrative support system for teachers and students.

Nos encontramos ante un sugerente trabajo en el que la profesora María José Bravo continúa, esta vez en solitario, con una línea de investigación en la que ha venido destacando en los últimos años, cuando coordinó, junto a la profesora Rosalía Rodríguez, dos interesantes obras colectivas: Mulier: algunas historias e instituciones de derecho romano (2013) y Mujeres en tiempos de Augusto: realidad social e imposición legal (2016). En esta ocasión, se servirá de dos poderosas figuras de la Roma antigua, Lucrecia y Cornelia, para indagar en algunas de las instituciones jurídicas e históricas más significativas dentro de la historia de la Roma republicana. Estas mujeres, así como los hechos que protagonizaron, tendrían una influencia futura que traspasará con mucho los límites espacio-temporales del mundo romano.

We are facing a suggestive work in which Professor María José Bravo continues, this time alone, with a line of research in which she has been standing out in recent years, when she coordinated, together with Professor Rosalía Rodríguez, two interesting works Collectives: Mulier: Some Histories and Institutions of Roman Law (2013) and Women in the Times of Augustus: Social Reality and Legal Imposition (2016). On this occasion, she will use two powerful figures from ancient Rome, Lucrezia and Cornelia, to investigate some of the most significant legal and historical institutions in the history of republican Rome. These women, as well as the events they starred in, would have a future influence that will go far beyond the space-time limits of the Roman world.

Dynamics of Power: an Architectural Reading of the Concentration of Power (Ullastret, 4th-3rd Century BC).
Authors: Cebrián Martínez David Jesús
Published: October 2018

Este artículo analiza el papel de la arquitectura doméstica en la construcción de narrativas de poder y su importancia como elemento clave para profundizar en el estudio y conocimiento tanto del sistema económico como del cambio social en los siglos IV-III aC. La investigación y posterior análisis de la arquitectura doméstica conduce a un conocimiento más profundo de la organización social además de aportar claves sobre la ideología imperante. Por otra parte, el cambio social se refleja a menudo en el hogar de la misma manera que en el patrón de asentamiento. Después de llevar a cabo el análisis empírico, la contribución de este ensayo se fundamenta en la tesis de que el poder puede ser concentrado.

This paper discuss the role of domestic architecture in the construction of narratives of power and its importance as a key feature to determine and analyse both the economic system and the social change in the 4th-3rd century BC. On the one hand, scrutiny of domestic architecture is a fruitful way by which to draw out a deeper insight with respect to social organisation, as well as being an indicator of ideology. On the other hand, social change is frequently reflected in the household in the same way as it is in settlement structure. After taking into account the empirical analysis, this paper contributes by determining that power can be concentrated for a number of reasons
The narrative framing of violence in teaching resources about the Spanish Conquest of America.
Authors: Bermúdez Vélez Ángela , Argumero Martínez Diego
Published: October 2018

La conquista de América (1492-1550) es un tema profundamente polémico que aún genera controversias por la violencia que conllevó y por la magnitud de sus consecuencias. Este estudio analiza cómo diferentes narrativas sobre la Conquista de América presentes en materiales educativos de historia utilizados en España y en Colombia, representan la violencia intrínseca a este proceso histórico. A través de un análisis narrativo y discursivo se identificaron cuatro narrativas principales: una narrativa de encuentro, una narrativa de modernidad, una narrativa de dominación y una narrativa de devastación. Cada una explica la conquista y enmarca la violencia de manera diferente. Los autores plantean que comprender cómo las narrativas históricas representan la violencia es fundamental para promover la construcción de culturas de paz desde la enseñanza de la historia.

The conquest of America (1492-1550) is a deeply contested topic that still generates controversy due to the violence it entailed and the magnitude of its consequences. This study analyzes how different narratives about the Spanish Conquest of America present in history education resources used in Spain and Colombia represent the violence intrinsic to this event. Data was analyzed through narrative and discursive theory. Four main narratives were identified: a Narrative of Encounter, a Narrative of Modernity, a Narrative of Domination, and a Narrative of Devastation.
Éléments d’une sémiotique de la narrativité musicale
Authors: Hauer Christian
Published: October 2018

Pour répondre à la question « à quel niveau sémiotique la musique communique-t-elle? », nous distinguons trois flux sémiotiques de la narrativité musicale. Le premier flux de narrativité est appelé « substance » : il correspond à la narrativité primaire, présente en toute musique, dans le son même. Le deuxième flux de narrativité est appelé « cadre » : il correspond à la manière dont le temps est organisé – problématisé – dans une oeuvre, un style, une époque. Le troisième flux de narrativité est appelé « intrigue » : il correspond à la mise en intrigue d’une oeuvre. Après avoir précisé en quoi celle-ci consiste, grâce au concept de « tension narrative », nous étudions son actualisation par l’auditeur, et plus précisément l’interaction entre le lecteur et le texte, en insistant sur trois facteurs qui rendent une telle interaction possible : l’intentionnalité, l’embodied simulation et les formes de vitalité.

What does music signify? And how do listeners make sense of music as a collection of sounding stimuli? A common way is to study the structure of the music, conceiving of music as a self-reflective system with elements that refer mainly to themselves. This is a position that deals with music in computational terms relying on symbols that can be manipulated at a virtual level of imagery, without any connection to the music as it sounds. Music, however, is also a temporal and sounding art. It can be described in acoustic terms, providing a totally objective rendition of the sonorous articulation through time. As such, there is a major distinction between “in time” and “outside of time” descriptions of the music, with the former relying on the first hand sounding stimuli and the latter on second-order symbolic replicas of the sounds.
Entendre (x) comme (une) oeuvre
Authors: Arbo Alessandro
Published: October 2018

Quel sens convient-il de donner à l’invite à « entendre (x) comme une oeuvre (musicale) »? Cette locution désigne une perception aspectuelle impliquant un type d’objet et un type d’attention. On vise l’action, dans la saisie des propriétés esthétiques, de connaissances relatives à la production de l’artefact. Si un premier niveau de compréhension coïncide avec la capacité à identifier les objets musicaux et à suivre leur concaténation, le passage au niveau supérieur dépend du repérage de références symboliques, intentionnelles et plus généralement contextuelles. À un premier niveau, on vise les propriétés (esthético-)expressives survenant sur les propriétés physico-phénoménales de l’objet musical; à un deuxième niveau, on se concentre sur les propriétés (esthético-) artistiques de l’oeuvre survenant sur les propriétés expressives et structurelles. En demandant à un auditeur d’entendre une musique comme oeuvre, nous l’invitons à identifier un type structurel dans les sons qu’il entend et à appliquer les dispositions qui lui permettent de choisir, parmi les propriétés esthétiques survenant sur la base physico-phénoménale, celles qui possèdent un intérêt artistique dans un contexte culturel donné.
Sémiotique, sens et démocratie. Oeuvres musicales et dispositifs participatifs
Authors: Esclapez Christine
Published: October 2018

Il s’agira dans cette contribution de questionner le sens du musical à partir de l’ancienne notion de « parole » issue de la linguistique saussurienne et de l’élargir à celle de « participation » qui connaît à l’heure actuelle un intérêt croissant dans notre monde contemporain. Cet arrière-fond théorique s’incarnera dans une « situation » particulière : le développement des dispositifs interactifs scène-artiste-public qui est progressivement devenu, depuis le début du XXIe siècle, le lieu d’une expérience artistique à échelle collective. Dans le champ musical, ces situations sont particulièrement effectives dans les concerts participatifs qui sont de véritables expériences, émotionnellement intenses car vécues collectivement en live. À la suite des travaux de la philosophe Joëlle Zask (2011), nous proposerons un protocole sémiotique qui permette d’analyser ces dispositifs sous l’angle de la réappropriation individuelle de la langue, de son individuation, de sa création ou re-création. Nous nous donnerons ainsi l’opportunité de retravailler notre rapport à la démocratie en considérant les concerts participatifs comme de possibles zones d’apprentissage (ou de réapprentissage) de notre engagement (ou ré-engagement) personnel.
Gestion de projet en systèmes d’information : mise en évidence de configurations de bonnes pratiques institutionnalisées
Authors: Farastier Armelle , Carton Sabine
Published: October 2018

Dans cette étude nous nous sommes intéressés aux bonnes pratiques de gestion de projet SI, telles qu’elles sont institutionnalisées au sein des entreprises au travers de différents types de vecteurs, à un instant donné, dans un contexte organisationnel donné (situation d’observation « post-adoption »). Cette analyse a été traitée selon une méthodologie quantitative grâce à une enquête réalisée auprès de chefs de projet SI portant sur 127 projets différents, complétée par des entretiens. Nous avons pu montrer que les pratiques institutionnalisées, au niveau du support organisationnel, se caractérisent différemment selon notamment le registre d’institutionnalisation qu’elles mobilisent (relationnel, symbolique, procédural ou matériel) et n’influent pas de la même manière sur les pratiques mises en oeuvre au niveau des projets.
The Pivotal Role of Guanxi for Economic Intelligence in the People’s Republic of China1
Authors: Milliot Eric
Published: October 2018

Economic intelligence can be defined as a system of learning (logic of knowledge) and lobbying (logic of influence), largely based on access to information and interpersonal relationships. In the West, learning and lobbying are managed simultaneously, sequentially or separately. Can these systems, however, be developed in the same ways in Far Eastern countries, where messages are generally implicit and relations are usually gregarious? In particular, does knowledge depend on influence in these countries?

Using the People’s Republic of China as an example, and based upon a survey of 353 people, the work in this article illustrates the need for adapting economic intelligence to international operations, and underlines the relevance of guanxi in building such a system in this country.
Les pôles de compétitivité, des formes organisationnelles aptes à innover en gestion des ressources humaines ?
Authors: Calamel Ludivine , Defélix Christian , Pichault François
Published: October 2018

Les mises en réseaux se développent de par le monde pour générer de l’innovation collaborative; en France, elles prennent notamment la forme des « pôles de compétitivité ». La littérature a analysé ces réseaux territoriaux d’organisations. Mais alors que leur feuille de route consiste également à produire de l’innovation managériale, via des pratiques de gestion des ressources humaines qui se situent à l’interface d’organisations différentes, l’état des connaissances reste faible sur ce point. Les pôles de compétitivité français représentent-ils une forme organisationnelle innovant également en gestion des ressources humaines ? A l’aune d’une approche contextualiste, mais aussi d’un cadre théorique associant entrepreneuriat institutionnel et acteur-réseau, cet article interroge les modalités de l’innovation managériale dans douze pôles de compétitivité français. Il met en lumière la principale innovation managériale de ces réseaux territoriaux : l’innovation de processus.
PME et firmes multinationales : performance des alliances asymétriques
Authors: Mahamadou Zoubeyda
Published: October 2018

L’objet de cet article est d’analyser les effets des asymétries existant entre les PME et les multinationales sur la performance de leurs relations d’alliance. Dans cette perspective, les asymétries ont été définies en termes de taille, de culture organisationnelle, de ressources et compétences et d’expériences dans de telles alliances. Les effets de ces asymétries sont analysés qualitativement du point de vue de dix PME françaises de l’industrie aéronautique.

Deux résultats principaux découlent de cette étude. Premièrement, certaines asymétries (taille, culture organisationnelle et expériences d’alliances) peuvent être à l’origine de difficultés relationnelles entre les partenaires. Cela dit, malgré les asymétries entre les partenaires, ces alliances génèrent des résultats positifs (performance financière et apprentissage organisationnel) grâce à la complémentarité entre les ressources apportées par les PME et des multinationales impliquées.
L’implication du conseil d’administration dans le processus stratégique des entreprises : le particularisme français
Authors: Ghaya Houda , Lambert Gilles
Published: October 2018

L’objectif de ce papier est d’étudier l’implication du Conseil d’Administration (CA) dans le processus stratégique afin de mieux comprendre son influence sur la performance de l’entreprise. Jusqu’où celui-ci doit-il s’investir pour ne pas nuire au développement de l’entreprise ? En mobilisant un cadre intégrateur de la théorie de l’agence et la perspective cognitive, nous menons une étude empirique sur un échantillon d’entreprises françaises cotées. Si nos résultats mettent en exergue un impact positif dans la phase d’initiation stratégique, une forte implication du CA dans les activités de mise en oeuvre et de contrôle semble au contraire être contreproductive.
Supporting a sugar tax in New Zealand: Sugar sweetened beverage (‘fizzy drink’) consumption as a normal behaviour within the obesogenic environment
Authors: Robertson Kirsten , Thyne Maree , Green James A.
Published: October 2018

Background

Excessive intake of sugar sweetened beverages (SSBs) is a preventable cause of death. While some countries have implemented a tax on SSBs, other countries, such as New Zealand, rely on industry self-regulation and individual responsibility, such as referring to labels, to control one’s own sugar intake from SSBs. The present study examines whether SSB consumers consciously control their diet and therefore interventions such as better labelling might be effective, or alternatively, whether SSB consumers engage in a general pattern of unhealthy eating, and in which case government regulation would be advisable.

Aim

To explore self-reported dietary consumption and conscious healthy eating behaviours of New Zealand consumers who had consumed SSBs over a 24 hour period.

Method

A cross-sectional survey of a representative sample of 2007 New Zealanders, measuring their food and beverage intake over a 24 hour period and self-reported intentions to eat healthily. Within this was a measurement of SSB consumption in the 24 hour period.

Results

Multivariable logistic regression revealed that compared to non-SSB consumers, SSB consumers were more likely to have eaten the following: confectionery; fast food; pre-prepared food; biscuits, cakes or pastries; takeaways; ice-cream/dessert. SSB consumption was also associated with a lower likelihood of referring to food labels, less conscious effort to eat healthily, and to less likely to avoid: sugar; fat; calories; food additives; pre-prepared food. SSB consumers were also less likely to have eaten breakfast, or made a meal at home made from scratch.

Conclusion

SSB consumers were more likely than non-SSB consumers to demonstrate a general pattern of unhealthy eating and were less likely to report consciously controlling their diet. The findings raise significant concerns regarding the efficacy of individual and industry self-regulation and lend support to stronger government targeted interventions.
Nitrobenzol – Bestimmung von Nitrobenzol in der Luft am Arbeitsplatz mittels Gaschromatographie nach Thermodesorption [Air Monitoring Methods in German language, 2018]

This analytical method is a validated measurement procedure for the determination of nitrobenzene [
98‐95‐3
] in workplace air in a concentration range of one tenth up to twice the currently valid OEL or MAK value of 0.51 mg/m
3
. With this method simultaneously airborne nitrobenzene in the gaseous state as well as particles are collected. Sampling is performed by drawing a defined volume of air through a quartz fibre filter located in the sampling head GGP‐Mini with an adsorption tube filled with Tenax TA connected downstream using a suitable pump. The flow rate is set to 0.066 L/min with a recommended air sample volume of approx. 4 litres. The collected nitrobenzene is thermally desorbed and then analysed by means of gas chromatography using two detectors, a FID for quantification and a MSD to recognise potential interferences. The quantitative determination is based on a calibration function obtained by means of a multi‐point calibration. The limit of quantification is 0.0085 mg/m
