Relação do Tempo de Ocupação das Estações com o Headway em Sistemas Metroviários usando Simulação Computacional – Aplicação no Sistema Metroviário do Rio de Janeiro
Authors: De Carvalho André Rodrigues , Alves Fábio , Ratton Neto Hostílio Xavier , Bender Juliane
Published: November 2017

Este trabalho trata da análise da relação entre o headway e o tempo de ocupação de estações utilizado pelos trens em sistemas metroviários. Usando um modelo de simulação de tráfego construído em Arena®, leva-se em consideração o tempo médio entre estações, a frequência de entrada dos trens no sistema e o tempo de ocupação das estações para medir o headway, para diversos cenários diferentes de tempo de ocupação na estação e prever o tempo total de viagem do trem. O modelo possui aplicação direta na faixa de horário crítico operacional dos sistemas metroviários e uma aplicação no metrô do Rio de Janeiro é utilizada para validar o modelo. As informações necessárias à simulação foram obtidas diretamente nas plataformas de embarque do metrô. O modelo de simulação permitiu obter um novo tempo de percurso para os trens provenientes do Uruguai e da Pavuna. Um modelo matemático auxiliar foi construído com os resultados da simulação e permite estabelecer o tempo de ocupação médio das estações e prever o headway médio do sistema. Com o headway médio e o tempo de ocupação médio das estações estabelecido, foi possível entender o comportamento do sistema na faixa horária de pico, descobrir o headway mínimo e contribuir para estudos futuros que busquem melhoria operacional em sistemas metroviários sem grandes investimentos em sistemas de controle do headway.

Authors: Alves Elcio Cassimiro , Souza Paula Mayer dos Santos , Da Gama Paulo Vitor Calmon Nogueira
Published: November 2017

O dimensionamento de pilares de concreto armado necessita atender às normalizações vigentes. Estruturas com pé-direito muito alto, ou duplo, podem conter pilares esbeltos. A utilização de pilares com índices de esbeltez entre 90 e 140 exige a consideração dos efeitos de segunda ordem pelo método do pilar-padrão ou pilar-padrão melhorado, com a curvatura da seção crítica obtida pelos diagramas de interação momento-força normal-curvatura (M, N, 1/r). Nesses casos, é obrigatória também a consideração da fluência. Este artigo se justifica pela pequena quantidade de estudos de pilares com este índice de esbeltez e será baseado na norma de procedimento para o projeto de estruturas de concreto (ABNT NBR 6118:2014). Definidas as verificações necessárias, o objetivo deste artigo passa a ser calcular a geometria otimizada (em função do custo de formas, aço e concreto) pelo método dos pontos interiores existente no software Matlab. Este estudo englobará pilares com resistência de concreto entre 20 e 90MPa.

Authors: Pereira Adalgisa Jesus , Santana Felipe Carvalho , Pereira Franklin Jesus , Tibiriçá Ariecha Vieira Rodrigues
Published: November 2017

A construção do conhecimento tradicional na agricultura ocorreu a partir de relações sociais baseadas no intercâmbio de conhecimento, sementes, e no desenvolvimento de relações tecnológicas mais harmoniosas com o ambiente. As tecnologias sociais e as técnicas usadas pelos agricultores são especialmente importantes entre os horticultores, pois a produção de hortaliças é complexa e exige cuidados diários. Para o conhecimento e socialização das tecnologias desenvolvidas por horticultores familiares aplicou-se entrevistas semiestruturadas e visitas às propriedades, apurou-se as técnicas desenvolvidas por horticultores agroecológicos da região da Zona da Mata de Minas Gerais, MG. Os resultados demonstraram que, mediante a escassez de recursos financeiros, horticultores agroecológicos desenvolvem formas de compostagem que viabilizam a produção e que aproveitam melhor o tempo no campo.

Com base nisso, o presente trabalho discutirá as atividades realizadas pelos membros do Centro Acadêmico de Química (CAQui) da UFV e as contribuições delas na formação dos graduandos. Para tanto, foram realizadas entrevistas com vinte e sete estudantes do curso de Química da UFV, divididos em três grupos: (i) os que nunca se envolveram com as atividades do CAQui; (ii) os membros recém-ingressos no CAQui; e (iii) os ex-membros do CAQui. As respostas foram transcritas e analisadas com base nas discussões das habilidades relativas ao empreendedorismo, tais como iniciativa, persistência, criatividade, eficiência, comprometimento, planejamento e trabalho em equipe. Considerando que a maioria das disciplinas curriculares não contribui para o desenvolvimento dessas habilidades, dado o caráter técnico de muitas delas, buscou-se compreender aqui como as atividades do CAQui podem favorecer o desenvolvimento de habilidades com o foco no empreendedorismo universitário. Ao final da pesquisa, verificou-se que todos os participantes envolvidos com o CAQui avaliam que tiveram a oportunidade de desenvolverem habilidades profissionais nas diversas atividades articuladas pelo Centro Acadêmico.
Stochastic dissipative quantum spin chains (I) : Quantum fluctuating discrete hydrodynamics
Authors: Bauer Michel , Bernard Denis , Jin Tony
Published: November 2017

Motivated by the search for a quantum analogue of the macroscopic
fluctuation theory, we study quantum spin chains dissipatively coupled
to quantum noise. The dynamical processes are encoded in quantum
stochastic differential equations. They induce dissipative friction on
the spin chain currents. We show that, as the friction becomes stronger,
the noise induced dissipative effects localize the spin chain states on
a slow mode manifold, and we determine the effective stochastic quantum
dynamics of these slow modes. We illustrate this approach by studying
the quantum stochastic Heisenberg spin chain.

Published: November 2017

Over a twelve year period one hundred and five neonates (30 females) with an anorectal malformation (ARM) were studied at a tertiary referral centre in Hong Kong. A perineal fistula was the most frequent presentation of ARM in males closely followed by rectourethral fistula. Vestibular fistula was the most common anomaly amongst females. An ARM without a fistula was documented in 11 % of patients and dominated by males. Associations and syndromes were present in nearly 30 % of the group with VACTERL association and Down syndrome at the forefront. Isolated anomalies were most frequently seen in the renal tract (23 %), the CNS (20 %) and the heart (18 %). A quarter of the cohort was small for gestational age with syndromes/associations featuring in half of this subgroup. A death rate of 9.5 % was recorded, of which all except one had an underlying syndrome or association. In addition a pre-existing heart condition constituted the most significant factor affecting the mortality in 50 % of this group.

The Lack of Neonatal Consequences in Pre-Eclampsia, Eclampsia and HELLP Syndrome: A Surprising Finding
Authors: Boyan William P , Shea Brian , Fiore Nicole , Shea Megan , Fenig Yaniv , Cohen Ian Thomas
Published: November 2017

Background: Knowledge of the correlation between maternal conditions, especially during pregnancy and fetal outcomes is paramount to optimal care in pediatrics. One which has not been frequently studied in the literature is pre-eclampsia, eclampsia and hemolysis, elevated liver enzymes and low platelets (HELLP).Methods: A retrospective review of all documented cases of pre-eclampsia, eclampsia and HELLP was done at a community Regional Neonatal Center. Over a five year period, 291 mothers were diagnosed with one of the three diseases and gave birth to 318 children. The children were stratified for gestational age and birth weight. Selected conditions were screened for in the medical record over the first year of life.Results: Of the 318 neonates, two were still births and one mother died from intracranial hemorrhage in the face of HELLP. Two hundred and twelve (66.67%) were born before 37 weeks, which is higher than the expected rate for these conditions. A total of 114 neonates were low birth weight (36%), while 75 were very low birth weight (23%). None of the conditions appeared significantly different for their suspected incidence when stratified for gestational age and birth weight.Conclusion: Eclampsia and HELLP are serious conditions in the pregnant patient, which significantly increase rates of preterm delivery, as well as correlates with low birth weights. As with all maternal conditions, thought must be given to the effect of these derangements on the developing fetus. Conditions such as necrotizing enterocolitis (NEC) caused by low flow sates and intestinal atresias, thought to occur with vascular incidents, were not seen at a higher rate in these patients once stratified for gestational age and birth weight.

Authors: Augustine Antony , Dutta Hemonta K , Boruah Deb K , Gogoi Rudra K
Published: November 2017

Background: MRI has not been traditionally used as an imaging modality for preoperative evaluation of ARM. It has been reserved for complicated ARM cases and Imaging in post-operative period. Aims: To study the role of MRI in preoperative evaluation of ARM patients, whether it be used as a single preoperative imaging investigation in ARM and what added advantage does it give to conventional imaging techniques. Settings and Design: Hospital based observational study was conducted over a period of 1 year which included 26 ARM patients who required preoperative imaging which was done using MRI.Methods and Material: Multi-planar T1 and T2WI images of pelvis were acquired followed by screening of abdomen done with coronal T2WI and screening of spine with T2FS sagittal images. Further sequences were acquired for evaluation of any target lesions as and when required. Images were evaluated for level of atresia, type of Fistula, additional anomalies in Vertebral / Spinal cord / Genital / Urinary system and sphincter muscle complex (SMC) development. Results were analysed using numbers, percentage and arithmetic mean.Results: MRI correctly identified the level of termination of rectal pouch in all patients. MRI correctly depicted the fistula in 89% cases. Seventy three percent cases had additional anomalies with 66% of cases with additional anomalies having multiple anomalies. MRI accurately evaluated SMC development in all cases.Conclusions: MRI provided elaborate pelvic anatomical details, precise information about the degree of development of pelvic musculature and information regarding the presence of additional anomalies in genitourinary and vertebra-spinal systems in a single sitting and without use of any ionizing radiation to child. We recommend MRI as the only needed imaging investigation in ARM cases before definitive surgical repair.

Published: November 2017

The present study was intended to obtain resistant cucumber varieties and to know the critical phase of cucumber plant towards Cucumber Mosaic Virus infection (CMV) therefore, it could be used as a basis for controlling the mosaic disease spread of CMV-induced at cucumber plants. The research was conducted in Baturiti Village Tabanan Bali within an insect-proof greenhouse. Elisa test was performed using CMV, WMV and PRsV antiserum. The resistance test of several cucumber varieties included Roberto, Harmony, Citra baby and Manggala was conducted by mechanical transmission from CMV inoculum source sap. Testing of cucumber plant critical phase of CMV infection was done by mechanically inoculating sap from CMV infected plant, for healthy cucumber plant as testing plant i.e. inoculation at 2, 3, 4, 5 and 6 weeks after planting and control (plant without CMV inoculation). An observation was done for incubation period variables, disease incidence, disease severity and crop yield. The results and conclusions of the four cucumber varieties tested were not found to be CMV resistant varieties, however, the moderately sensitive Harmony varieties deserve attention for choosing in the cultivation. The cucumber plant that was CMV infected from the age at planting until 4 weeks after planting shows 100% disease incidence and plants could not produce fruits. The critical phase of cucumber plant towards CMV infection occurred from the time at planting until 4 weeks after planting.

Budgetary Process in India: An Analysis
Authors: Sahoo Jitendra
Published: November 2017

“A Budget tells us what we can’t afford, but it doesn’t keep us from buying it”-William Feather (American Publisher; Author-1889-1981)(Holzer and Schwester 2011 p.289). In almost all the forms of government budget or budgeting falls within the jurisdiction of bureaucracy. The preparation of budget falls within the jurisdiction of public administration which is run and manned by civil servants. Hence budgeting is an important function of bureaucracy. But it alone cannot do everything about budgeting. In a parliamentary system of government every department is headed by a minister and at the head of finance department there is a minister who is called as finance minister The preparation of estimated expenditure and income is done under the guidance of the finance minister. In this paper I have tried my best to highlight the process of Indian budget with it’s historical development in a lucid manner.
Refinement of transformation algorithms for the transitions between state coordinate system and cities local coordinate system
Authors: Zalutsky V. T.
Published: November 2017

Some improvements of the coordinates transformation algorithms, related with application of the cartographic plane coordinates in the Russia’s state coordinate system(SCS) and local coordinate systems of the cites(LCSC), are presented in the article. A comparative analysis of the cited sources allowed to eliminate discovered misspells. After corrections, the formulae were revised using a common logic of transformation and notation system. As a result the author obtained three groups of equivalent transformation algorithms, they implement the «direct» (from SCS to LCSC) and «inverse» (from LCSC to SCS) transitions. Compiled algorithms preserve the identity of sources and authors. Checking of the updated algorithms performed using the test examples from well knowing manuals. Computations according to the considered algorithms with data from one of the examples are demonstrated in the final part of the article. Practical verification of the work of the above mentioned algorithms on real data was repeatedly performed in the course of the production activity of the Engineering Survey Department of the Irkutskzheldorproekt Institute. In particular, in works related to research for the design of reconstruction and repair of railway tracks, with the updating of obsolete engineering and topographic plans of stations, also using catalogs of coordinates of points of the special reference system of the East Siberian Railway.

Anapa bay bar is a valuable recreational-medical resource. Digital landscape-morphological mapping of its the Northern-Western part was created by digital aero survey materials for monitoring of its statement. Compiled maps show that in the Western part of region dune belt is degradated, front dune hills destroyed due to spreading of settlement Veselovka buildings to beach, and due to mass enactments carrying out at bay bar of lake Solenoe. Here it is necessary to decide the problem of defense from waves flooding by construction of artificial hills. The middle part of region, around Bugaz lagoon, is using for unregulated recreation of extreme sportsmen – windsurfing and kiting – with seasonal recreation in camping from tent-city and campers. Many short roads to sea beach, orthogonal to coast line, have been transformed to corridors of blowing and sea waves interaction to lagoon lowland with dune belt destroying. In the Eastern part of region, at Bugaz bay bar, dune belt is conserve, it changes under natural sea and wind processes action. At some places sea waves are erode windward front dune slope. Just everywhere sand accumulative trains are forming at leeward slope of front dune. Showed peculiarities of landscape morphological structure mast be taken in account due treatment of measures for bay bar defense and keeping.

Authors: Suthari Sateesh , Kiran Boda Ravi , Prasad Majeti Narasimha Vara
Published: November 2017

Alternanthera philoxeroides (alligator weed) grows abundantly in polluted Peri-urban Greater Hyderabad, India. It is collected at no cost and sold in the market as a leafy vegetable in the name of “Ceylon Spinach”. The plant accumulates iron (Fe), manganese (Mn), cadmium (Cd), lead (Pb) and zinc (Zn) in roots and leaves. Soil samples were analyzed for pH, EC, available nitrogen (N), phosphorus (P) and potassium (K) and showed significant metal concentrations of Pb, Mn and Zn, which varied from one location to another. The metal accumulation order in the plants is root>leaf>stem in all the studied sites. The results revealed that the massive roots of alligator weed are effective in the bioconcentrating Fe, Mn, Zn, Pb and Cd, although the plant parts are rich in nutraceuticals like phenolics and antioxidants. Therefore, low income community prefers to consume it as vegetable. However, its consumption as a leafy vegetable can cause health risks.
cis- and trans- regulation controls of human meiotic recombination at a hotspot
Authors: Ergören Mahmut C. , Neumann Rita , Berg Ingrid , Jeffreys Alec J.
Published: November 2017

PRDM9 plays a key role in specifying meiotic recombination hotspot locations in humans. To examine the effects of both the 13-bp sequence motif (cis-regulator) and trans-regulator PRDM9 on crossover frequencies and distribution, we studied Hotspot DA. This hotspot had the motif at its centre, and a single nucleotide polymorphism (SNP) that disrupts the motif. The crossover frequency showed Hotspot DA to be a regular hotspot with an average crossover rate (~8 X10-4) among hotspots assayed on autosomes. Our results show that, comparing the rates and distributions of sperm crossover events between donors heterozygous for the disrupting SNP showed that there was a huge asymmetry between the two alleles, with the derived, motif-disrupting allele completely suppressing hotspot activity. Intensive biased gene conversion, both in to crossovers and noncrossovers, has been found at Hotspot DA. Biased gene conversion that influences crossover and non-crossover hotspot activity correlates with PRDM9 allele A. In Hotspot DA, the lifetime of the hotspot mostly depends on the cis-regulatory disrupting SNP, and on the trans-regulatory factor PRDM9. Overall, our observation showed that Hotspot DA is the only evidence for human crossover hotspot regulation by a very strong cisregulatory disrupting SNP.
Organic selenium effect on body temperature and body weight in broilers
Authors: Răduță Adrian , Curcă Dumitru
Published: November 2017

The research was conducted on a group of 20 3-weeks-old chicken from the Cobb breed that were divided into two batches. Both batches received a 21/1 ratio feed diet for broiler chicken in their finishing period. The experimental group feed was supplemented with 0.5 ppm selenium, with 0.25 ALKOSEL R397 g/kg mixed fodder. 30 days into this feeding regime, the following determinations were made weekly: body weight, body temperature and computerized thermography of the comb and wattle. The obtained results were tabled and bio statistically analyzed revealing that individuals in the experimental batch showed statistically significant increases of the values for body weight (average body weight was 14.78% larger than that of the control batch) and of the temperature measured in the combs (average temperature was 12.97% higher) and wattles (average temperature was 4.12% higher). The experimental group also registered a higher core body temperature, but not statistically significant in comparison with the control group. Association of the higher values of core and peripheral body temperature with increased body weight in the individuals from the experimental group, correlated with an increased number of red blood cells and lower cholesterol levels suggest an improved basal metabolism and a better feed conversion.

Authors: Jamir Kizukala , Kottapalli Seshagirirao
Published: November 2017

The methanolic extract of ten Zingiberaceae taxa were evaluated for their phytochemical constituents, total phenolic and flavonoid contents along with in-vitro antioxidant and antimicrobial activities. Among the extracts, Kaempferia parviflora and Zingiber montanum were the most potent reducing agents, while Zingiber officinale exhibited strong free radical-scavenging activity. The high phenolic content observed in Z. montanum, Z. officinale and Curcuma longa may be attributed to the strong antioxidant activity. Furthermore, the extracts of C. longa, K. parviflora and Z. montanum effectively inhibite the growth of test pathogenic microbes. This study suggest that the ginger species are promising source of natural of antioxidant with strong antimicrobial properties.
Fresh, Mechanical and Absorption Characteristics of Self-Consolidating Concretes Including Low Volume Waste PET Granules
Authors: Mermerdaş Kasım , Nassani Dia Eddin , Sakin Mehmet
Published: November 2017

This study evaluates the effect of waste polyethylene terephthalate (PET) granules on the fresh, mechanical and absorption characteristics of self-consolidating concretes (SCCs). Fine aggregates were replaced with different percentages (from 0% to 8%) of PET granules obtained by crushing waste PET bottles. The fresh properties of SCC containing PET granules were determined using slump flow and V-funnel flow time tests. Mechanical properties (compressive strength and splitting tensile strength tests) and absorption properties (sorptivity and water absorption tests) were evaluated. The results indicated that utilization of waste PET granules in production of SCC could be an effective way for recycling purpose. The maximum amount of PET replacement should be limited to 5%. Exceeding 5% of PET content may result in an increase of V-funnel flow time to overpass the limiting value, decrease in compressive strength, reduction in sorptivity and increase in the water absorption. The production of high performance SCC containing 5% PET granules satisfies all the requirements for SCC with satisfactory outputs.

Published: November 2017

Ports are the main centers of economic activities and producers of environmental pollutions on the shores and urban areas. Regarding the growth of world trade, transportation of goods through the ports has been undergoing prompt development, possibly experiencing further progress in the upcoming years. In the recent years, the destructive impacts of ports on the environment has been increasing. The type of activities and interactions carried out in the ports have speeded up such destructions. The major sources of pollutions are usually air, noise, water, soil and garbage. The objective of this study is to identify the main and sub-indices in the assessment of environmental impacts of ports (EIAP). To this end, a number of 28 case studies over the world have been analyzed. The indices of the environmental impacts of ports are categorized and evaluated according to four scales: the application and study aspects, the time, the location, as well as the quantity of occurrence of the criteria. Totally 200 main and sub-indices have been identified, within which, the first 10 have been allocated to the pollution of air, noise, water, transportation, traffic, greenhouse gases, garbage, soil, climate change and dredging, since 2000 to 2016. Finally, to better understand the subject, the conceptual framework for EIAP is presented. This study provides with port managers guidance toward identifying significant environmental aspects of ports; it is, at the same time, applicable in order for awareness and prioritization in the environmental management.
Experimental Investigation of Damage Detection in Beam Using Dynamic Excitation System
Authors: Kouhdaragh Mehdi
Published: November 2017

Most structural failures are due to break in consisting materials. These breaks begin with a crack, the extension of which is a serious threat to the behaviour of structure. Thus the methods of distinguishing and showing cracks are the most important subjects being investigated. In this article, a new smart portable mechanical system to detect damage in beam structures via using fuzzy-genetic algorithm is introduced. Acceleration-time history of the three points of beam is obtained. The signals are then decomposed into smaller components using new EMD (Empirical Mode Decomposition) method with every IMF containing a specific range of frequency. The dominant frequencies of the structure are obtained from these IMFs using Short-term Fourier transform. Subsequently, a new method of damage detection in simply supported beams is introduced based on fuzzy-genetic algorithm. The new method is capable of identifying the location and intensity of the damage. This algorithm is developed to detect the location and intensity of the damage along the beam, which can detect the damage location and intensity based on the pattern of beam frequency variations between undamaged and damaged states.
Numerical Modelling of Flow in Morning Glory Spillways Using FLOW-3D
Authors: Razavi Amir Reza , Ahmadi Hassan
Published: November 2017

Suspended load amount with flow is one of the factors which are disregarded in designing morning glory spillways. It is due to the fact that physical modeling of sediment load with flood flow is very difficult and costly. Suspended sediments load with flow can change the density of passing water, leading to changing most of assumptions existing in spillways' design. With its unique potential to model dense flows and flows contain suspended loads, numerical model of FLOW-3D can provide valuable information in this regard. In the present study, flow was calibrated and validated using FLOW-3D through physical model. Then, by adding suspended load to flow, the values of discharge passing through the morning glory spillway were determined. In this regard, applying suspended load (3000, 6000, 9000, and 12000 ppm), flow discharge values were investigated for various heads over the spillway. The research findings revealed that increasing suspended flow load leads to decreasing values of flow passing through the morning glory spillways; such that, deceased values strongly depend on suspended load.

Concrete is a versatile and cost-effective building material whose properties are influenced by age, curing condition, and installation. A number of studies deduced that there should be an association of benefits encouraged the use of partial replacements of cement seems to improve strength and durability properties of concrete. This paper presents a framework for feasibility assessment and determination of optimum percentage of rice husk ash (RHA) replacement. Five mix plans with RHA replacing ratio of 0-20% and constant micro- silica value by 10% were prepared. Tests results indicated that compressive strength increased by 20% with an increase in RHA up to 15%. The similar trend was observed in mix designs made of cement replaced by RHA up to 20% in water absorption coefficient measurement. Higher chloride ion penetration was observed in mix designs containing 25% RHA compared to that of conventional concrete. Mixes developed a slightly higher impact resistance than the control mix.

The primary objective of this study is exploring the moisture susceptibility of unmodified and SBS-modified hot and warm mix asphalt mixtures. To this end, two different WMA additives including Aspha-min and Sasobit were employed to fabricate WMA specimens. The moisture susceptibility of warm polymer modified asphalt (WPMA) mixes was evaluated using modified Lottman test at 25°C according to AASHTO standard (T 283). In addition, the effect of different percentages of hydrated lime (from 0% to 2%) and Zycosoil (from 0% to 0.1%) as anti-stripping additives on the moisture susceptibility of the mixtures was explored. Based on the ITS test results, WPMA prepared with Sasobit additive and polymer modified asphalt (PMA) mixes satisfied the desirable tensile strength ratio (TSR) (above 80%) but Aspha-min WPMA mixes had TSR lower than 80%.
Application of Bed Load Formulations for Dam Failure and Overtopping
Authors: Hosseinzadeh-Tabrizi Seyed Alireza , Ghaeini-Hessaroeyeh Mahnaz
Published: November 2017

The Enhanced HLLC scheme as a robust approximate Riemann solver is used for numerical modeling of three different test cases of mobile bed and stepped mobile bed in dam failure and dam overtopping conditions. The current research has been done in the frame of the finite volume method using shallow water equations along with the Exner equation for sediment continuity. The Ribberink, Wong and Parker formulations have been used for the modelling of bed load movement. A convenient approach based on the Boussinesq hypothesis is deployed for considering turbulence effects in the second case. The affections of stepped and slope condition for the flow bed are considered through a corrected version of the HLLC flux components. Finally, the model is applied for modelling overtopping in the third case. The results of the present model are relatively reasonable by comparing with the experimental data.
L’entrepreneuriat social : un nouveau paradigme ?
Authors: Chabanet Didier , Richard Damien
Published: November 2017

Comment l’« entrepreneuriat social » a-t-il pu en venir à concurrencer en France la notion d’« Économie sociale et solidaire » (ESS) ? La première explication est liée au tournant néolibéral amorcé au début des années 1980. La seconde relève du positionnement des différentes parties prenantes : tandis que l’influence de l’État et de l’ESS statutaire décline, d’autres acteurs collectifs portent haut et fort, dès le début des années 2000, l’étendard de l’entrepreneuriat social. La troisième raison est liée à la crise de 2008, qui propulse l’entrepreneuriat social au cœur de l’actualité politique. Trois séquences différentes – l’Initiative pour l’entrepreneuriat social lancée par la Commission européenne en octobre 2011, la loi-cadre française du 31 juillet 2014 consacrée à l’ESS, enfin les travaux de la Taskforce du G8 sur l’investissement à impact social en juin 2013 – renforcent cette configuration globale. Le législateur français a introduit une rupture majeure en donnant la possibilité à des entreprises commerciales d’intégrer le champ de l’ESS, dès lors qu’elles poursuivent un but d’« utilité sociale » et qu’elles adoptent une gouvernance participative.
La théorie C-K, cadre « naturel » pour innover en politique ?
Authors: Lageat Erwan , Lafon Dominique
Published: November 2017

Les promesses de changement sont intimement liées au politique dans ses dimensions rhétoriques et idéologiques, au point de constituer un des piliers de son message. Pourtant, ce n’est plus vers la théorie politique que l’on se tourne aujourd’hui pour renouveler les perspectives. Une certaine représentation de l’innovation semble en effet avoir dépossédé le politique de son pouvoir d’inspiration, en monopolisant la capacité d’évocation de la rupture. Il existe pourtant un espace d’invention accessible au politique pour restaurer un champ d’innovation original et légitime. Le raisonnement de conception innovante, tel que l’envisage la théorie C-K 1 , avance en effet « dans l’inconnu », au-delà des fixations sur les bonnes pratiques, des références technologiques et des freins supposés du politique. Son caractère générique le rend mobilisable dans tous les contextes ; il est génératif de grammaires conceptuelles qui invitent à l’exploration de champs de connaissances originaux, capables de dégager un horizon politique innovant. Cette primauté du raisonnement de conception innovante sur la technologie pourrait être un mode original de revendication de l’innovation par le politique.
Appréhender l’élu au prisme de l’orientation entrepreneuriale
Authors: Dethou Valentin , Husson Julien , Schmidt Christophe
Published: November 2017

Au travers d’apports théoriques et d’une étude de cas menée au sein d’une agence de développement et d’urbanisme, cet article revient sur le concept émergent d’élu-entrepreneur et sur son élément central : l’orientation entrepreneuriale. Alors que la littérature est presque exclusivement axée sur la dimension individuelle du concept (la personne de l’élu), la recherche dont nous présentons ici les résultats insiste sur l’interaction élu/organisation.
Un paysage contemporain des sciences de l’éducation au filtre des évaluations des unités de recherche (2011-2016)
Authors: Lebeaume Joël
Published: November 2017

À partir des données disponibles dans les dossiers et rapports d’évaluation des unités de recherche, cet article actualise l’état des lieux de la recherche en éducation et formation, effectué au milieu des années 1990. Le paysage contemporain, partiel car ne couvrant que les unités de recherche qui ont sollicité leur évaluation dans ce secteur disciplinaire, porte principalement sur les effectifs et la structuration des activités de recherche. L’analyse des données met en évidence que les unités, de taille variable, sont situées, en transition, remembrées régionalement et composites. Avec le rappel des éléments conjoncturels et contextuels de la politique de recherche et de ses évolutions récentes, l’ensemble invite à discuter les orientations stratégiques pour le développement des sciences de l’éducation.
Gaston Mialaret (1918-2016) ou « l’effort d’institutionnalisation » des sciences de l’éducation
Authors: Hedjerassi Nassira
Published: November 2017

Dans le cadre d’une recherche sur l’histoire des sciences de l’éducation, au croisement de la sociologie et de l’histoire des sciences (sociales), je cherche à comprendre comment un groupe d’acteurs a participé à l’institutionnalisation de ce champ disciplinaire. Dans cet article, je m’intéresse à la figure de Gaston Mialaret, l’un des acteurs de ce groupe. À partir de différentes sources (entretiens, archives, correspondances, publications), je reconstitue des éléments de son parcours professionnel et militant (sur le plan pédagogique). La participation à des associations, qu’il a pu animer, créer, présider, a jalonné son parcours, jouant comme moteur de développement et d’institutionnalisation de cette discipline.
Évolution démographique et rapport au travail des enseignant.e.s-chercheur.e.s en sciences de l’éducation : des logiques sexuées à l’œuvre ?
Authors: Barthes Angela , Hedjerassi Nassira
Published: November 2017

Les effectifs des enseignant.e.s-chercheur.e.s en sciences de l’éducation (discipline relativement récente) passent de 114 en 1978 à 668 en 2015 et cette augmentation s’accompagne d’un processus de féminisation. Pour autant, les carrières académiques sont ségréguées sur le plan sexué, avec 35,8 % de professeures. Une enquête exploratoire auprès d’un échantillon représentatif portant sur leurs représentations du métier, les activités de recherche et d’enseignement, ainsi que les rapports que ces universitaires entretiennent face aux transformations du travail et du monde universitaire met en lumière des logiques sexuées marquées.
