Authors: Glaveckaitė Sigita , Peldžius Ričardas , Grebelis Arimantas , Šerpytis Pranas , Laucevičius Aleksandras
Published: April 2018

This case report describes the diagnostic and treatment challenges of the combined disc impediment caused by pannus ingrowth in combination with thrombus formation in a 21-mm Medtronic-Hall aortic valve prosthesis. A combined obstruction of a Medtronic-Hall prosthesis in the aortic position is a rare, but potentially fatal clinical condition for the first time reported in Vilnius University Hospital Santariškių Klinikos. Despite the difficulties in determining a correct diagnosis, our critically ill patient was clinically stabilized by partially successful thrombolysis and then successfully treated by a surgical thrombectomy together with pannus excision during the rotation of the disc within the valve housing 3 years after the valve implantation.

Published: April 2018

Background and Objective. The aim of this study was to establish whether Lithuanian women would request an elective cesarean section in a low-risk pregnancy and to compare how the women’s opinion changed during the 5-year period. Material and Methods. A study was conducted at the Hospital of Lithuanian University of Health Sciences from November 1 to December 31, 2006, and from January 1 to February 28, 2011. A total of 204 and 239 women were enrolled in 2006 and 2011, respectively. Self-administered anonymous questionnaires collected information on women’s knowledge about the advantages of the different modes of delivery and their preferred type of birth in a low-risk pregnancy. Results. Overall, 82.4% of the participants in 2006 and 74.5% in 2011 thought that women should be able to choose the mode of delivery in a low-risk pregnancy. If they had had such an opportunity, 15.2% of women in 2006 and 14.9% in 2011 would have chosen cesarean section without any medical indication. The most frequently mentioned advantage of vaginal delivery was that it is natural, while safety for the newborn and the possibility of avoiding delivery pain were the mentioned advantages of cesarean section. Conclusions. Approximately 15% of Lithuanian women would request an elective cesarean section, and this percentage did not change during the 5-year period. While the national cesarean section rate is increasing with every year, it seems that “maternal request” cannot be blamed for this phenomenon. Despite all the available information about the different modes of delivery, women still lack professional and reliable knowledge about it.
Heredity of Cognitive Functions and Personality in Twins
Authors: Kalasūnienė Loreta , Goštautas Antanas , Sinkus Algimantas
Published: April 2018

Background and Objective. The inheritance of cognitive functions and personality is still a problem under investigation. A classical method, investigation of twins, is often used to find relative contributions from genetics and the environment to quantitative traits. The aim of this study was to investigate a possible influence of heredity on cognitive functions (by applying the Raven test) and personality traits (according to the Eysenck’s theory) in twins. Material and Methods. In total, 139 pairs of same-sex twins were investigated. The zygosity of the twin pairs was confirmed through genotyping with 15 molecular DNA markers. Constructive thinking was assessed using the Raven test. Personality assessment was conducted using the Eysenck Personality Questionnaire (EPQ) in Lithuanian. Results. The difference in the total number of incorrect solutions between monozygotic (MZ) and dizygotic (DZ) twin pairs younger than 15 years was not significant; however, in the group older than 15 years, this difference was found to be significant. Based on the total number of incorrect solutions, the concordance in the MZ twins was greater than in the DZ twins. The same tendency was found with cumulative EPQ scores on the extraversion scale. Conclusions. The results imply that the quality of cognitive functions and personality traits (extraversion) can be influenced by heredity. This confirms previous findings on the heritability of cognitive factors and personality traits.
Maskless Surface Modification of Polyurethane Films by an Atmospheric Pressure He/O2 Plasma Microjet for Gelatin Immobilization
Authors: Zhang Man , Dai Yichuan , Wen Li , Wang Hai , Chu Jiaru
Published: April 2018

A localized maskless modification method of polyurethane (PU) films through an atmospheric pressure He/O2 plasma microjet (APPμJ) was proposed. The APPμJ system combines an atmospheric pressure plasma jet (APPJ) with a microfabricated silicon micronozzle with dimension of 30 μm, which has advantages of simple structure and low cost. The possibility of APPμJ in functionalizing PU films with hydroxyl (–OH) groups and covalent grafting of gelatin for improving its biocompatibility was demonstrated. The morphologies and chemical compositions of the modified surface were analyzed by scanning electronic microscopy (SEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The fluorescent images show the modified surface can be divided into four areas with different fluorescence intensity from the center to the outside domain. The distribution of the rings could be controlled by plasma process parameters, such as the treatment time and the flow rate of O2. When the treatment time is 4 to 5 min with the oxygen percentage of 0.6%, the PU film can be effectively local functionalized with the diameter of 170 μm. In addition, the modification mechanism of PU films by the APPμJ is investigated. The localized polymer modified by APPμJ has potential applications in the field of tissue engineering.

Published: April 2018

The aim of the study was to investigate the combined association of adherence to a Mediterranean diet (MedDiet) and muscular fitness (MF) with cardiometabolic health in collegiate students. The present cross-sectional analysis consisted of 1248 (714 females) healthy collegiate students (20.1 ± 2.7 years old). Adherence to a MedDiet was assessed by a KIDMED (Mediterranean Diet Quality Index) questionnaire. Standing broad jump, standing vertical jump, and isometric handgrip dynamometry were used as indicators of MF. The cardiometabolic profile was assessed using the following components: triglycerides, blood pressure, triglycerides, high-density lipoprotein (HDL)-cholesterol, glucose, and waist circumference. Analysis of covariance shows a significant difference in the cardiometabolic profile of both genders between the high MF/low MedDiet and high MF/optimal MedDiet groups, and the low MF/low MedDiet and low MF/optimal MedDiet groups (p < 0.001). No difference was found on cardiometabolic profile between high MF/optimal MedDiet and high MF/low MedDiet, both in males and females. Additionally, logistic regression shows that both female (odds ratio (OR) = 2.01; 95% confidence interval (CI): (1.8–3.7); p = 0.02) and male (OR = 3.38; 95% CI: (1.9–5.8); p < 0.001) participants in the optimal MedDiet/high MF group had the highest odds of expressing a healthier cardiometabolic profile as compared to those in the low MF/low MedDiet group. In conclusion, a combination of high MF levels and optimal adherence to a MedDiet is associated with a healthier cardiometabolic profile; however, high MF levels seem to circumvent the deleterious effects of having a low adherence to a MedDiet.

Published: April 2018

Background: Our objective was to quantify to what extent the association between adherence to the French nutritional recommendations at midlife, measured by the Programme National Nutrition Santé-Guideline Score (PNNS-GS), and healthy aging (HA) is mediated by body mass index (BMI) status. Methods: We analyzed data from 2249 participants of the French ‘Supplementation with Vitamins and Mineral Antioxidants’ (SU.VI.MAX-‘SUpplémentation en VItamines et Minéraux AntioXydants’) cohort. At baseline (1994–1995), data on BMI status (<25 vs. ≥25 and <30 vs. ≥30) and diet were collected. At follow-up (2007–2009), HA status (yes/no) was evaluated via a multidimensional concept focusing on chronic disease incidence, physical and cognitive functioning, mental and social health, pain, and perceived health. Relative risks (RR) were estimated by extensively adjusted robust-error-variance Poisson regression, and counterfactual-based mediation analysis was performed. Results: Our HA criteria were met by 39% of participants. We identified a positive direct relation of a greater adherence to the French nutritional recommendations, with the probability of HA (RRQuartile 4 vs. quartile 1 = 1.31 (95% confidence interval (CI) = 1.13, 1.53)), and an indirect relation mediated by BMI status (1.01 (95% CI: 1.01, 1.02)), accounting for 5% of the total relation. Conclusion: These results indicate that high dietary quality may contribute to the preservation of overall health during aging, partly via obesity prevention and partly via other mechanisms.
Influence of Tropical Instability Waves on Phytoplankton Biomass near the Marquesas Islands
Authors: Martinez Elodie , Raapoto Hirohiti , Maes Christophe , Maamaatuaihutapu Keitapu
Published: April 2018

The Marquesas form an isolated group of small islands in the Central South Pacific where quasi-permanent biological activity is observed. During La Niña events, this biological activity, shown by a net increase of chlorophyll-a concentration (Chl, a proxy of phytoplankton biomass), is particularly strong. It has been hypothesized that this strong activity is due to iron-rich waters advected from the equatorial region to the Marquesas by tropical instability waves (TIWs). Here we investigate this hypothesis over 18 years by combining satellite observations, re-analyses of ocean data, and Lagrangian diagnostics. Four La Niña events ranging from moderate to strong intensity occurred during this period, and our results show that the Chl plume within the archipelago can be indeed influenced by such equatorial advection, but this was observed during the strong 1998 and 2010 La Niña conditions only. Chl spatio-temporal patterns during the occurrence of other TIWs rather suggest the interaction of large-scale forcing events such as an uplift of the thermocline or the enhancement of coastal upwelling induced by the tropical strengthening of the trades with the islands leading to enhancement of phytoplankton biomass within the surface waters. Overall, whatever the conditions, our analyses suggest that the influence of the TIWs is to disperse, stir, and, therefore, modulate the shape of the existing phytoplankton plume.

Published: April 2018

Fiber micro-knots are a promising and a cheap solution for advanced fiber-based sensors. We investigated complex fiber micro-knots in theory and experiment. We compared the measured spectral response and present an analytical study of simple micro-knots with double twists, twin micro-knots, figure-eight micro-knots, and tangled micro-knots. This research brings the simple fabrication process and robustness of fiber micro-knots into the world of complex resonators which may lead to novel optical devices based on fiber micro-knots.
Prior Puma Lentivirus Infection Modifies Early Immune Responses and Attenuates Feline Immunodeficiency Virus Infection in Cats
Authors: Sprague Wendy , Troyer Ryan , Zheng Xin , Wood Britta , Macmillan Martha , Carver Scott , VandeWoude Susan
Published: April 2018

We previously showed that cats that were infected with non-pathogenic Puma lentivirus (PLV) and then infected with pathogenic feline immunodeficiency virus (FIV) (co-infection with the host adapted/pathogenic virus) had delayed FIV proviral and RNA viral loads in blood, with viral set-points that were lower than cats infected solely with FIV. This difference was associated with global CD4+ T cell preservation, greater interferon gamma (IFN-γ) mRNA expression, and no cytotoxic T lymphocyte responses in co-infected cats relative to cats with a single FIV infection. In this study, we reinforced previous observations that prior exposure to an apathogenic lentivirus infection can diminish the effects of acute infection with a second, more virulent, viral exposure. In addition, we investigated whether the viral load differences that were observed between PLV/FIV and FIV infected cats were associated with different immunocyte phenotypes and cytokines. We found that the immune landscape at the time of FIV infection influences the infection outcome. The novel findings in this study advance our knowledge about early immune correlates and documents an immune state that is associated with PLV/FIV co-infection that has positive outcomes for lentiviral diseases.
Does BCA3 Play a Role in the HIV-1 Replication Cycle?
Authors: Rumlová Michaela , Křížová Ivana , Zelenka Jaroslav , Weber Jan , Ruml Tomáš
Published: April 2018

The cellular role of breast carcinoma-associated protein (BCA3), also known as A-kinase-interacting protein 1 (AKIP-1), is not fully understood. Recently, we reported that full-length, but not C-terminally truncated, BCA3 is incorporated into virions of Mason-Pfizer monkey virus, and that BCA3 enhances HIV-1 protease-induced apoptosis. In the present study, we report that BCA3 is associated with purified and subtilisin-treated HIV particles. Using a combination of immune-based methods and confocal microscopy, we show that the C-terminus of BCA3 is required for packaging into HIV-1 particles. However, we were unable to identify an HIV-1 binding domain for BCA3, and we did not observe any effect of incorporated BCA3 on HIV-1 infectivity. Interestingly, the BCA3 C-terminus was previously identified as a binding site for the catalytic subunit of protein kinase A (PKAc), a cellular protein that is specifically packaged into HIV-1 particles. Based on our analysis of PKAc–BCA3 interactions, we suggest that BCA3 incorporation into HIV-1 particles is mediated by its ability to interact with PKAc.

Published: April 2018

Hyperglycemia causes perioperative complications and many anesthetics impair glucose metabolism and cause hyperglycemia. We evaluated the effects of propofol on blood glucose metabolism and insulin secretion during an intravenous glucose tolerance test (IVGTT) in dogs. Blood glucose, insulin, triglyceride, cholesterol, and free fatty acid (FFA) levels were measured in dogs during IVGTT in a conscious state and under the effect of 2.0% isoflurane, low-concentration propofol (0.2 mg/kg/min), and high-concentration propofol (0.4 mg/kg/min) anesthesia. Plasma glucose levels significantly increased in all of the treatment groups when compared with those in the conscious group. The prolonged half-life period of plasma glucose suggested that isoflurane and propofol attenuated glucose metabolism in dogs. Plasma insulin levels were significantly lower in the isoflurane group when compared with those in the other groups, whereas blood FFA levels were increased in the propofol groups when compared with the other groups. These results suggest that propofol itself does not directly raise plasma glucose levels, but attenuates glucose metabolism by accumulating FFA.
Corn Straw as a Solid Carbon Source for the Treatment of Agricultural Drainage Water in Horizontal Subsurface Flow Constructed Wetlands

Published: April 2018

Agricultural drainage water with a low C/N ratio restricts the nitrogen and phosphorus removal efficiencies of constructed wetlands. Thus, there is a need to add external carbon sources to drive the nitrogen and phosphorus removal. In this study, the effects of the addition of corn straw pretreated with different methods (acid treatment, alkali treatment, and comminution) on treating agricultural drainage water with a low C/N ratio were investigated in constructed wetlands. The results showed that soaking the corn straw in an alkaline solution was the most suitable pretreatment method according to the release rule of chemical oxygen demand (COD) and the dissolution of total nitrogen (TN) and total phosphorus (TP). The average removal efficiency of TN and TP in constructed wetlands increased respectively by 37.2% and 30.5% after adding corn straw, and by 17.1% and 11.7% after adding sodium acetate when the hydraulic retention time (HRT) was 3 days. As an external carbon source, straw was cheap, renewable, and available. In contrast, the sodium acetate demanded high costs in a long-term operation. Therefore, corn straw had a great advantage in treatment effect and cost, which improved the treatment efficiency of agricultural drainage water using a byproduct of agricultural production as a slow-release carbon source.
Comparing the Sensitivity of Bank Retreat to Changes in Biophysical Conditions between Two Contrasting River Reaches Using a Coupled Morphodynamic Model
Authors: Rousseau Yannick Y. , Biron Pascale M. , Van de Wiel Marco J.
Published: April 2018

Morphodynamic models of river meandering patterns and dynamics are based on the premise that the integration of biophysical processes matching those operating in natural rivers should result in a better fit with observations. Only a few morphodynamic models have been applied to natural rivers, typically along short reaches, and the relative importance of biophysical parameters remains largely unknown in these cases. Here, a series of numerical simulations were run using the hydrodynamic solver TELEMAC-2D, coupled to an advanced physics-based geotechnical module, to verify if sensitivity to key biophysical conditions differs substantially between two natural meandering reaches of different scale and geomorphological context. The model was calibrated against observed measurements of bank retreat for a 1.5 km semi-alluvial meandering reach incised into glacial till (Medway Creek, Ontario, Canada) and an 8.6 km long sinuous alluvial reach of the St. François River (Quebec, Canada). The two river reaches have contrasting bed and bank composition, and they differ in width by one order of magnitude. Calibration was performed to quantify and contrast the contribution of key geotechnical parameters, such as bank cohesion, to bank retreat. Results indicate that the sensitivity to key geotechnical parameters is dependent on the biophysical context and highly variable at the sub-reach scale. The homogeneous sand-bed St. François River is less sensitive to cohesion and friction angle than the more complex Medway Creek, flowing through glacial-till deposits. The latter highlights the limits of physics-based models for practical purposes, as the amount and spatial resolution of biophysical parameters required to improve the agreement between simulation results and observations may justify the use of a reduced complexity modelling approach.
Proximity effect in a two-dimensional electron gas coupled to a thin superconducting layer
Authors: Reeg Christopher , Loss Daniel , Klinovaja Jelena
Published: April 2018

There have recently been several experiments studying induced superconductivity in semiconducting two-dimensional electron gases that are strongly coupled to thin superconducting layers, as well as probing possible topological phases supporting Majorana bound states in such setups. We show that a large band shift is induced in the semiconductor by the superconductor in this geometry, thus making it challenging to realize a topological phase. Additionally, we show that while increasing the thickness of the superconducting layer reduces the magnitude of the band shift, it also leads to a more significant renormalization of the semiconducting material parameters and does not reduce the challenge of tuning into a topological phase.
THE MICRO- AND SMALL ENTERPRISES IN CREATIVE PROFESSIONAL SERVICES: A BUSINESS MODEL PERSPECTIVE
Authors: PFEIFER Sanja , STANIĆ Marina , OBERMAN PETERKA Sunčica
Published: April 2018

Advertising, architecture and design are perceived as an important subset of the creative industries and as having an increasing role in innovations and competitiveness of economies. However, issues such as identifying the underlying business model (BM) of the micro- and small enterprises in these industries, the manner in which BMs evolve or the degree to which their evolution is innovative remains unresolved. In the context of creative professional services (CPSs), an analysis of the six case studies involving microenterprises indicates a heterogeneity in designing BMs. Talented professionals, sophisticated management of human resources and creativity processes as well as trustworthy partners are considered generic components of value creation, whereas personalized relationships with customers are a generic component of value delivery in advertising, architecture and design. In addition, the findings indicate that microenterprises in advertising, architecture and design have a capacity to differentiate themselves from the rest of the competition through creation of complex and radical changes in their BMs.
Stellar Yields of Rotating First Stars. II. Pair-instability Supernovae and Comparison with Observations
Authors: Takahashi Koh , Yoshida Takashi , Umeda Hideyuki
Published: April 2018

Recent theory predicts that first stars are born with a massive initial mass of ≳100 M
⊙. Pair-instability supernova (PISN) is a common fate for such massive stars. Our final goal is to prove the existence of PISNe and thus the high-mass nature of the initial mass function in the early universe by conducting abundance profiling, in which properties of a hypothetical first star is constrained by metal-poor star abundances. In order to determine reliable and useful abundances, we investigate the PISN nucleosynthesis taking both rotating and nonrotating progenitors for the first time. We show that the initial and CO core mass ranges for PISNe depend on the envelope structures: nonmagnetic rotating models developing inflated envelopes have a lower shifted CO mass range of ∼70–125 M
⊙, while nonrotating and magnetic rotating models with deflated envelopes have a range of ∼80–135 M
⊙. However, we find no significant difference in explosive yields from rotating and nonrotating progenitors, except for large nitrogen production in nonmagnetic rotating models. Furthermore, we conduct the first systematic comparison between theoretical yields and a large sample of metal-poor star abundances. We find that the predicted low [Na/Mg] ∼ −1.5 and high [Ca/Mg] ∼0.5–1.3 abundance ratios are the most important to discriminate PISN signatures from normal metal-poor star abundances, and confirm that no currently observed metal-poor star matches with the PISN abundance. An extensive discussion on the nondetection is presented.

Published: April 2018

The collection of the Museu Oceanográfico D. Carlos I is a historical specimen, instrument, and document collection that has been housed at the Aquário Vasco da Gama since 1935. The collection is largely the result of several scientific campaigns conducted by Dom Carlos de Bragança between 1896 and 1907. Specifically, the ichthyological collection consists of 675 surviving catalogue records of specimens caught, acquired or offered to D. Carlos I between 1892 to 1907, and includes the type specimen for Odontaspisnasutus Bragança, 1904 (junior synonym of Mitsukurinaowstoni Jordan, 1898), along with several specimens of deep sea species. All specimens were captured in coastal Portuguese waters, and were preserved in alcohol, formalin, or mounted.

Published: April 2018

Streams in urban areas are strongly impacted by the input of organic matter and metals, for instance copper (Cu) and zinc (Zn). These metals are essential for the aquatic biota, but when absorbed in excess they are toxic. In Chironomidae larvae, the deleterious effects of heavy metals can be ascertained by analyzing the morphological deformities of the larval mentum, a structure of the oral cavity. In this study, we evaluated I) the bioavailability of Cu and Zn in urban stream sediments and II) the relationship between Cu and Zn concentrations and the incidence of deformities in the mentum of Chironomus larvae. Chironomid flies were collected from four locations in two streams at an urban area in southern Brazil. They were identified and the incidence of deformities in the mentum was quantified. Sediment samples were collected at the same locations where larvae were collected, to quantify the bioavailable fractions of Cu and Zn. The concentrations of Cu in the sediment were similar between the collection sites. However, Zn concentrations varied among sites, being greater in the stretch directly influenced by the input of the organic waste. In total, 2,895 Chironomid larvae were collected. The incidence of deformities in the mentum was above 30% and was correlated with the concentrations of Cu (r = 0.68) and Zn (r = 0.87). This correlation indicates that the municipal waste that is thrown into the city’s streams has influenced the occurrence of deformities.

Parenté et biotechnologies
Authors: Porqueres i Gené Enric
Published: April 2018

L’article questionne le caractère exceptionnel souvent attribué aux con­textes biotechnologiques de la parenté. Il montre que les contextes de la PMA tout comme les systèmes de parenté traditionnellement étudiés par les anthropologues insistent sur la porosité des corps à la base de la définition de l’inceste, plus petit dénominateur commun de la parenté. Outre la prise en compte des logiques corporelles, il est également question dans le texte des ancrages métaphysiques de tout système de parenté. Par ailleurs, que ce soit en contexte biotechnologique ou au sein des systèmes embryologiques étudiés traditionnellement par les anthropologues, la dramatisation d’un processus d’individuation pré linguistique fournit des clés de compréhen­sion : l’Ego de la parenté s’inscrit dans un corps qui est lieu de relations constituantes. Cependant, pour qu’il puisse habiter le système de parenté, cet Ego doit être aussi accueilli en tant que futur « Je » du langage. L’article montre que l’entrée comme utilisateur légitime dans le langage est la condi­tion sine qua non pour toute expérience humaine, a fortiori donc pour celle de la parenté.

Published: April 2018

Cet article étudie l’accès à la parenté de sept familles homoparentales féminines (FHF) avec enfant né de la volonté du couple. Envisageant cet accès comme une succession de décisions prises dans un contexte déterminé, il montre que les FHF ne bouleversent pas les principes de base du modèle de parenté euraméricain mais les réinterprètent en créant un nouvel idiome relationnel destiné à faire exister et reconnaître une double maternité. Dans une démarche quasi expérimentale, les FHF mettent ainsi en œuvre une parenté réflexive.
Résidence alternée
Authors: Hachet Benoît
Published: April 2018

La résidence alternée, qui est une des modalités d’organisation de la vie des enfants après la séparation conjugale, est l’objet de polémiques récurrentes en France depuis plus de dix ans. Ces controverses, principalement entrete­nues par les « professionnels de l’enfance », ont pour objet le bien-être des enfants. Livre noir et Livre blanc se répondent sur une problématisation psychologique de la question, en faisant apparaître des modèles opposés de parentalité. L’objet de l’article est d’utiliser ce débat comme révélateur des normes de parentalité contemporaines. Cohabitent aujourd’hui un modèle conservateur qui vise à défendre les rôles traditionnels de genre et un mo­dèle nouveau de coparentalité. Les données disponibles sur les séparations montrent le poids persistant de la prévalence maternelle auprès des enfants aussi bien dans les cours de justice que dans les pratiques parentales quoti­diennes.

Ce texte propose une clarification de la réalité complexe et polysémique associée au terme de « politique industrielle », dans une perspective analytique et historique des années 1980 à nos jours. Nous distinguons trois périodes correspondant à trois politiques industrielles idéales-typiques : la politique de la concurrence, la politique de promotion de l’innovation et de la compétitivité et la politique visant le changement structurel. Notre contribution envisage aussi les différentes théories économiques qui fournissent les fondements analytiques des différentes politiques industrielles de ces dernières décennies.
Les comportements de détention de liquidités dans les sociétés non financières du G7 ont-ils évolué depuis la crise ?
Authors: Broyer Sylvain , Schneider Emmanuel , Verluise Cyril
Published: April 2018

Les entreprises ont accumulé des niveaux de cash sans précédent depuis la crise financière. Une idée couramment répandue est que le motif de précaution en serait le principal facteur : l’accumulation de cash résulterait des difficultés d’accès au financement bancaire que les entreprises ont subies lors de la crise financière. Nous observons ici l’évolution de la détention de liquidités par les entreprises du G7 et réalisons un test économétrique afin d’identifier si la crise financière a amené un changement de régime dans la détention de liquidités. Nos résultats indiquent que la hausse des liquidités ne s’explique par le motif de précaution que dans les pays du G7 où la désintermédiation des financements externes a progressé depuis la crise (États-Unis, Grande-Bretagne, Japon). En Europe continentale, nos tests infirment l’hypothèse d’un changement de régime de détention du cash.
Clusters et efficacité du capital-risque : une analyse des stratégies différenciées des fonds indépendants et des fonds industriels
Authors: Dufour Dominique , Nasica Eric , Torre Dominique
Published: April 2018

Les investisseurs en capital risque indépendants (IVC) se distinguent des organismes captifs, ces derniers étant des filiales de banques, de sociétés industrielles ou d’organismes publics. On attribue généralement aux premiers une meilleure rentabilité etune meilleure sélectivité des projets et aux seconds de moindres performances. L’objectif de notre papier est d’établir les limites de ces conclusions dans le cas des capital-risqueurs filiales de sociétés-mères industrielles, les capital-risqueurs industriels ou Corporate Venture Capitalists (CVC). A l’aide d’un modèle théorique prenant appui sur des faits stylisés, nous retrouvons tout d’abord les résultats traditionnels allant dans le sens d’une meilleure efficacité des IVC, en mettant en évidence à la fois le rôle des ressources spécifiques et des comportements stratégiques des deux types de capital-risqueurs. Nous observons aussi qu’à défaut d’améliorer la rentabilité moyenne des projets financés, les CVC en accroissent dans tous les cas le nombre. Puis, nous introduisons la prise en compte de synergies entre projets, notamment au sein de clusters. Quand de telles interactions sont introduites, nous montrons que les CVC peuvent non seulement contribuer à financer davantage de projets mais aussi accroître la sélectivité globale du secteur. Nous illustrons ces résultats par des simulations numériques et les commentons en conclusion.

Le débat sur les relations entre les secteurs financiers et non financiers de l’économie est un vieux débat. Schumpeter (1911) soutint qu’un système financier efficient et efficace a un impact positif sur la croissance économique. Récemment, ce débat a été ravivé par la crise financière, qui a révélé la croissance extraordinaire du secteur financier dans les dernières décennies, l’écart croissant entre les sphères financière et réelle de l’économie, et la financiarisation des entreprises. En fait, le secteur financier est devenu si important et réalise des profits si élevés qu’il est légitime de se demander si cette tendance n’a pas limité les changements structurels des secteurs industriels, en limitant ses ressources non seulement financières mais aussi humaines, étant donné que l’évidence est que beaucoup d’ingénieurs ont préféré travailler dans le secteur financier pour obtenir des salaires plus élevés que dans l’industrie. Pendant ce temps, les industries ont connu des changements structurels importants, impliquant la nécessité d’importants investissements à tel point qu’elles ont appelé les gouvernements à réaliser des politiques industrielles pour soutenir ces changements, conduisant à un « retour » des politiques industrielles. L’objectif de cet article est d’analyser les effets de cette financiarisation sur les secteurs industriels et les implications en termes de politiques industrielles. Ces dernières devraient comprendre des mesures qui induisent le secteur financier à se refocaliser sur l’approvisionnement des industries en ressources financières. Les politiques financières et macroéconomiques doivent être cohérentes avec les politiques industrielles de sorte que toutes les parties du système économique puissent se combiner pour s’engager sur un sentier de développement soutenable.
Pour une approche systémique de l’innovation « environnementale »
Authors: Debref Romain
Published: April 2018

Depuis une vingtaine d’années, prenant en considération l’impact environnemental de leurs technologies, les acteurs économiques cherchent à réaliser des innovations environnementales s’inscrivant dans une perspective de développement soutenable. Pourtant, vingt ans après le Sommet de la Terre de Rio, les frontières de ces innovations restent encore problématiques d’un point de vue théorique. C’est pourquoi nous reviendrons sur la manière dont elles sont étudiées et observées par la théorie économique dominante. Nous avançons qu’une approche systémique permet clairement d’identifier ses défaillances et ses frontières poreuses. Notre travail se déroule en trois étapes. La première s’arrête d’abord sur l’analyse des éléments formant l’identité des innovations environnementales. Restant statique, cette étape est complétée dans un deuxième temps par une approche dynamique qui nous permettra de mieux appréhender son processus d’évolution et ses déterminants. Enfin, une troisième étape mettra en résonance cette dynamique avec celle de l’environnement. Les résultats de notre travail expliquent pourquoi il est difficile de cerner une innovation environnementale ex ante et ex post. De plus, les diverses contributions théoriques en matière d’innovation environnementale privilégient davantage la résolution de problèmes environnementaux que la définition de ce qu’est l’« environnement » : cela pose la question de l’appropriation du concept. Enfin, cette résolution passe par la réduction de l’exploitation des ressources, souvent présentée comme une solution immédiate favorable à la préservation environnementale, mais peut détériorer davantage la biosphère sur le long terme à cause d’effets rebonds.
Typologie et stratégies des plateformes de distribution en ligne des jeux vidéo : panorama et enjeux concurrentiels
Authors: Davidovici-Nora Myriam
Published: April 2018

Aujourd’hui, la distribution en ligne des jeux vidéo devient le mode dominant de distribution. Nous observons une multitude d’acteurs sur différents segments qui ont adopté des modèles de distribution variés. Nous cherchons à expliquer ces positionnements en confrontant les observations empiriques aux éléments d’analyse de la théorie économique des plateformes. Nous observons que les choix technologiques (être producteur de hardware ou de logiciels, être propriétaire de ces ressources technologiques, avoir des ressources technologiques dédiées aux jeux vidéo ou généralistes) et le degré d’intégration verticale influencent les stratégies de développement suivies par les principales plateformes et expliquent les différences en termes de création et développement des effets de réseaux directs et croisés. Notre recherche permet donc de comprendre le développement et l’évolution de la distribution en ligne des jeux vidéo tout en relevant les principaux enjeux concurrentiels actuels.
L’évolution des modèles d’affaires dans les industries créatives : l’exemple de la presse en ligne en France (2004-2014)
Authors: Lyubareva Inna , Rochelandet Fabrice
Published: April 2018

La diffusion massive des technologies numériques et de leurs usages a largement transformé les modèles économiques et les pratiques de consommation dans les industries créatives et culturelles. Cette étude vise précisément à analyser la dynamique de l’innovation dans le cas des modèles d’affaires de la presse en ligne. Nous montrons qu’en raison de l’incertitude générée par ces transformations, mais également de traits institutionnels du secteur de la presse en France, un processus isomorphique a abouti entre 2007 et 2014 à la réduction de la diversité des modèles d’affaires et à l’émergence de trois designs dominants : les « numériques a minima », les « pure players » et les « leaders explorateurs ». Cette analyse s’appuie sur la construction et l’exploitation statistique d’une base de données originale portant sur un échantillon représentatif de 100 sites d’information en ligne en France et retraçant leur évolution entre 2006 et 2014.
Environmental performances in Europe: An empirical analysis of the convergence among manufacturing sectors
Authors: Gilli Marianna , Mazzanti Massimiliano , Morleo Giovanni
Published: April 2018

Cette étude se concentre sur les performances environnementales de l’industrie manufacturière européenne. Notre objectif est de tester l’existence de β-convergence, absolue et conditionnelle, ainsi que la convergence σ de la productivité environnementale (c’est-à-dire, pour chaque secteur, rapport entre valeur ajoutée et émissions de dioxyde de carbone) de 14 secteurs pour la période 1995-2009 en utilisant la base de données WIOD. Les résultats soutiennent l’hypothèse de la β-convergence et mettent en évidence d’autres facteurs tels que l’ouverture commerciale. Enfin, les résultats indiquent que la valeur ajoutée sectorielle peut affecter les performances environnementales, comme l’accélération de convergence. Aucune preuve statistique de σ-convergence n’est trouvée.
Adopter une vision dynamique de l’innovation soutenable : le cas des circuits courts alimentaires
Authors: Brûlé-Gapihan Élodie , Laude Audrey , Maclouf Étienne
Published: April 2018

À partir du cas des circuits courts alimentaires, cet article met en évidence l’importance d’adopter une vision dynamique des innovations soutenables. Nous montrons que l’agriculture biologique, puis les circuits courts, trouvent leur origine au sein d’un même projet de réponse aux dérives environnementales et sociales de l’agriculture conventionnelle. Cependant, face au développement de cette première contestation qu’est l’agriculture biologique, le régime dominant – fondé sur le secteur conventionnel – n’est pas resté passif. Il a intégré cette innovation en l’adaptant à l’échelle industrielle. En réponse, le projet de contestation s’est renouvelé autour de la question de l’autonomie des exploitations, d’où le recours aux circuits courts. Cette dernière innovation soutenable semble aujourd’hui suivre le même trajet que l’agriculture biologique, intégrée et adaptée à l’industrie agroalimentaire. Notre analyse est qualitative et repose sur l’historique du développement des circuits courts en France. Elle aboutit à une proposition de modèle inspirée par l’approche Multi-Level Perspective. L’originalité de notre démarche est de mettre en évidence une dynamique des innovations soutenables, qui interagissent et se reformulent par le biais d’interactions avec le régime dominant.
Sustainable innovation and frugal innovation: Exploring the relationships between Innovation and sustainability
Authors: Le Bas Christian
Published: April 2018

Ce papier constitue une tentative de positionner innovation soutenable et innovation frugale par rapport aux principes de durabilité. Notre contribution vise à analyser ensemble ces deux types d’innovation très récemment traités dans la littérature relevant des études sur l’innovation. L’innovation soutenable relie les efforts d’innovation avec les performances environnementales et les améliorations des relations sociales. En revanche, l’innovation frugale est définie comme un nouveau paradigme technologique, principalement provoqué par la recherche de produits à bas coûts à destination des classes pauvres ou des consommateurs les moins riches. Nous décrivons comment et pourquoi ces deux types d’innovation constituent des nouveautés. On avance également que l’innovation frugale possède des propriétés de durabilité. Enfin, on considère les deux types d’innovation comme des innovations responsables, une nouvelle catégorie dans le champ des études d’innovation. Cet article tend à clarifier la relation entre innovation et durabilité.

Estudo transversal de abordagem quantitativa que objetivou analisar o dimensionamento de profissionais da enfermagem frente à ocorrência de eventos adversos. Foi realizado em unidade de internação cirúrgica de um hospital universitário. Os dados foram coletados em 94 pacientes, entre 23 de março a 14 de abril de 2015. A média de internação foi de 8,46 dias. Internaram em média 21,6 pacientes classificados com cuidados mínimos, 2,7 com intermediários e 1,1 com semi-intensivos. O aplicativo E-dimensionamento demonstrou quantitativo de 25 profissionais conforme as exigências do Conselho Federal de Enfermagem. Quanto ao número de profissionais, verificou-se uma média diária de 1,8 enfermeiro no período matutino, dois no vespertino e um no período noturno. Sobre o quadro de profissionais de nível médio, foi possível identificar uma média de 5,2 profissionais no período matutino, quatro no período vespertino e três no período noturno. Das 252 avaliações, foi observada a ocorrência de 20 eventos adversos entre: infecção do sitio cirúrgico, perda do acesso venoso, infecção do acesso venoso e quedas. Conclui-se que mesmo com um quadro de profissionais adequado, houveram eventos adversos, entretanto, quando o quadro de pessoal diminuiu os eventos adversos aumentaram significativamente, o que permite inferir que estas ocorrências podem estar relacionadas a múltiplos fatores, dentre eles o quantitativo de profissionais.

O objetivo do estudo foi realizar uma revisão integrativa em bases de dados para verificar a produção científica (inter) nacional sobre instabilidade postural e a condição de fragilidade física em idosos. Trata-se de uma revisão integrativa realizada nas bases de dados LILACS, MEDLINE, SciELO e PubMed, no período de 2001 a 2016.Incluíram-se artigos originais diretamente relacionados ao tema, disponíveis na íntegra, nos idiomas português e inglês. A busca inicial resultou em 483 artigos e, após critérios pré-estabelecidos de inclusão e exclusão, 24 artigos perfizeram o corpus da revisão. As publicações apresentaram crescimento recente com destaque para a literatura internacional. Emergiram três categorias temáticas: instabilidade postural associada ao envelhecimento: causas e consequências; reconhecimento da fragilidade física e instabilidade postural: relações e associações; e intervenções para a reabilitação do equilíbrio postural. A instabilidade postural associa-se ao processo de envelhecimento, como um marcador de fragilidade física e da saúde da pessoa idosa. Os resultados oferecem subsídios para fortalecer a gestão de cuidados preventivos da progressão da síndrome da fragilidade.
