Neoliberalismo e integración “de hecho” en el Cono Sur: Argentina como exportadora de hidrocarburos
Authors: Sabbatella Ignacio
Published: December 2017

Entre 1989 y 2001 se configuró un proceso de integración energética en el Cono Sur de América, en el cual Argentina adoptó el papel de exportador de petróleo y gas natural, a pesar de que históricamente había tenido que importar una parte de los hidrocarburos y sus derivados necesarios para cubrir la demanda interna. El objetivo de este artículo es analizar por qué y cómo se insertó Argentina como proveedor de hidrocarburos en este proceso. Como hipótesis, se argumenta que fue menos una política de Estado que una consecuencia indirecta de la reforma neoliberal del sector de hidrocarburos, cuyos pilares fueron la desregulación del mercado, la privatización de la petrolera estatal Yacimientos Petrolíferos Fiscales Sociedad del Estado (ypf) y la transformación simbólica y material del petróleo y gas en commodities. En términos de la cepal (1994), se trató más de una integración “de hecho” que de una integración impulsada por políticas. Tomando en cuenta estudios previos sobre la reforma del sector, se aplicó una estrategia metodológica basada en la investigación documental (Valles, 1997), a través de la recolección, sistematización y análisis de datos secundarios.
Más allá de perspectivas miopes en el estudio de las audiencias. Investigaciones etnográficas de audiencias no-occidentales en la era digital: el caso africano
Authors: Tufte Thomas
Published: December 2017

Este artículo propone la descolonización y provincialización de la investigación de las audiencias. Las tendencias actuales de la investigación de audiencias reflejan la dominancia de un discurso anglosajón y el uso de conceptos que emergen de realidades anglosajonas particulares. En este texto, se presentan y analizan estudios de otras regiones, África y América Latina en especial, que ofrecen otras ideas y retan a lo que se denominaría miopía dentro de los estudios de audiencia. La miopía se refiere tanto al enfoque empírico, como a la naturaleza de la producción de conocimiento, que emergen de los estudios contemporáneos de audiencias. Este artículo busca ir más allá de la documentación y celebración de la diversidad dentro de la investigación de audiencias globales. A partir de las nociones de epistemología del sur, epistemología de la ceguera y ver de Boaventura de Sousa Santos, se defiende una sensibilidad, amplitud y matices en la producción del conocimiento que puedan contribuir a una comprensión verdaderamente global del público en la era digital.
Doing Well by Making Well: The Impact of Corporate Wellness Programs on Employee Productivity
Authors: Gubler Timothy , Larkin Ian , Pierce Lamar
Published: December 2017

This paper investigates the impact of a corporate wellness program on worker productivity using a panel of objective health and productivity data from 111 workers in five laundry plants. Although almost 90% of companies use wellness programs, existing research has focused on cost savings from insurance and absenteeism. We find productivity improvements based both on program participation and postprogram health changes. Sick and healthy individuals who improved their health increased productivity by about 10%, with surveys indicating sources in improved diet and exercise. Although the small worker sample limits both estimate precision and our ability to isolate mechanisms behind this increase, we argue that our results are consistent with improved worker motivation and capability. The study suggests that firms can increase operational productivity through socially responsible health policies that improve both workers’ wellness and economic value, and provides a template for future large-scale studies of health and productivity.

Unbiased Estimators and Multilevel Monte Carlo
Authors: Vihola Matti
Published: December 2017

Multilevel Monte Carlo (MLMC) and recently proposed unbiased estimators are closely related. This connection is elaborated by presenting a new general class of unbiased estimators, which admits previous debiasing schemes as special cases. New lower variance estimators are proposed, which are stratified versions of earlier unbiased schemes. Under general conditions, essentially when MLMC admits the canonical square root Monte Carlo error rate, the proposed new schemes are shown to be asymptotically as efficient as MLMC, both in terms of variance and cost. The experiments demonstrate that the variance reduction provided by the new schemes can be substantial.

Interprofessional bedside teaching: setting up a novel teaching programme
Authors: Watson Kathryn , Mainwaring Cathryn , Moran Amy , Jangi Fahmeda B , Raguseelan Nira , Simpson Thomas , Lasoye Tunjil , Mustafa Omar G
Published: December 2017

Background:

An ageing population and health-care advances mean that patients have increasingly complex medical health and social needs, requiring a multidisciplinary team. However, despite working as an interprofessional team, team members still largely train in professional silos. Furthermore health-care professionals report a poor understanding of the skills of colleagues from different professions. This article describes the set up and outcomes of a novel interprofessional bedside teaching programme.

Methods:

An in-centre interprofessional teacher training course was established to facilitate interprofessional bedside teaching, along with supported ward-based sessions to apply the skills.

Results:

Three in-centre courses and five workplace sessions have run, with forty-five and twenty-eight interprofessional participants respectively. Statistically significant improvements in confidence facilitating interprofessional teaching were seen, with participants more likely to teach at the bedside and involve the multidisciplinary team.

Conclusions:

This article shows evidence of a teaching programme which improves the confidence of the multidisciplinary team in facilitating interprofessional bedside teaching.

A través de este estudio se pretende dar relevancia a los elementos que componen el marketing sensorial, destacando su potencial para la mejora de la experiencia de compra del usuario en el punto de venta. Para llevar la investigación a cabo, se ha adaptado el modelo de Hulten, Broweus y Van Dijk (2009) sobre el marketing sensorial con el objetivo principal de analizar la percepción y las actitudes de los consumidores ante distintos elementos sensoriales de comunicación propuestos por la tienda sevillana Blanco Número 1. El método que se utilizó fue, por un lado, una investigación documental y, por el otro, un estudio exploratorio causal-cuantitativo consistente en crear una estrategia sensorial. Los resultados obtenidos arrojan luz sobre la importancia del marketing sensorial, pues, en este caso real, existe un aumento considerable de las ventas, el tiempo de permanencia de los clientes e, incluso, la satisfacción de los mismos después de aplicar las estrategias pertinentes. Por ello, se ha concluido que el modelo de Hulten, Broweus y Van Dijk es válido y fiable para un establecimiento comercial pequeño como el que ha sido objeto de estudio.
Processo eletrônico: Perspectivas de eliminação das etapas mortas do procedimento
Authors: Coelho Fábio Alexandre , Quinaia Cristiano
Published: December 2017

A Ciência Processual evolui gradativamente conforme a realidade social buscando cada vez mais oferecer uma tutela jurisdicional efetiva e célere. No contexto da pós-modernidade cibernética, o Processo Eletrônico surge como proposta que objetiva trazer economia de tempo na tramitação do procedimento. No Brasil, a Emenda Constitucional n. 45 trouxe expressamente a garantia de duração razoável do processo a partir de 2004. Para alcançar esse objetivo, diversas foram as mudanças legislativas e administrativas, inclusive a estipulação de metas e a aprovação de um novo Código de Processo Civil. Na Itália, quando da reforma processual, a doutrina destacou que o grande óbice à justiça tempestiva eram as etapas mortas do procedimento. Nesse compasso, resta imperioso abeberar na doutrina italiana a tese das etapas mortas à luz da qual se desenvolve uma análise da contribuição da tecnologia ao sistema judiciário brasileiro. Com o presente trabalho, objetiva-se analisar a importância da reforma administrativa e tecnológica do Poder Judiciário, em detrimento das sucessivas mudanças legais.
Policy advocacy: contribuições para a construção de um conceito a partir de uma revisão sistemática da literatura
Authors: Da Silva Viviane Regina
Published: December 2017

A prática de policy advocacy implica em dar voz política a uma mensagem ligada à defesa de uma causa, como instrumento de influência da opinião pública e dos tomadores de decisão. O presente artigo visa contribuir para fomentar os estudos sobre a ascensão do fenômeno de policy advocacy na contemporaneidade e suscitar o debate desta temática no âmbito acadêmico nos campos de estudos de Direitos Humanos e Políticas Públicas. Complementarmente poderá corroborar com a discussão da temática entre os tradicionais atores de direitos humanos e políticas públicas no Brasil, pois sabe-se que o desenvolvimento de estudos planejamento de estratégias de policy advocacy é de interesse das organizações nacionais e internacionais do terceiro setor, de grupos de pressão, think tanks, movimentos sociais, mídias tradicionais e sociais e do próprio governo. Face ao exposto, o presente artigo objetivou levantar as divergências conceituais acerca da definição de policy advocacy por intermédio da metodologia de revisão sistemática da literatura e análise de conteúdo, demonstrando a evolução conceitual e seus distintos pontos de vista, de modo a contribuir para a construção de um conceito adequado para a literatura nacional, contemplando a característica interdisciplinar dos campos de estudos de Direitos Humanos e Políticas Públicas. A partir de uma revisão sistemática da literatura constatou-se que no Brasil, ainda são recentes as pesquisas sobre policy advocacy e, a princípio, a maioria dos estudos concernentes a esta temática apresentam ênfase nos modelos de análise e na caracterização dos processos de negociação das políticas setoriais específicas, estando o termo policy advocacy fortemente associado às terminologias de Advocacy Coalition Framework (ACF), Advocacy e Media Advocacy.
PERFORMANCE OF CEMENT COMPOSITES REINFORCED WITH SURFACE-MODIFIED POLYPROPYLENE MICRO- AND MACRO-FIBERS
Authors: Antoš Jakub , Dejdar Lukáš , Trejbal Jan , Prošek Zdeněk
Published: December 2017

This paper focuses on the mechanical properties investigation of cement pastes reinforced with surface treated polymer fibers. The cement matrix was composed of Portland cement (CEM I 42.5 R, w/c ratio equal to 0.4). Two polypropylene fiber types (micro- and macro-fibers) were used as randomly distributed and oriented reinforcement in volume amount of 2 %. The fibers were modified in the low-pressure inductively coupled cold oxygen plasma in order to enhance their surface interaction with the cement matrix. The investigated composite mechanical properties (load bearing capacity and response during loading) were examined indirectly by means of four-point bending mechanical destructive tests. A response of loaded samples containing treated fibers were compared to samples with reference fibers. Moreover, cracking behavior development was monitored using digital image correlation (DIC). This method enabled to record the micro-cracks system evaluation of both fiber reinforced samples.

SYNTHESIZED ENRICHMENT FUNCTIONS FOR EXTENDED FINITE ELEMENT ANALYSES WITH FULLY RESOLVED MICROSTRUCTURE
Authors: Doškář Martin , Novák Jan , Zeman Jan
Published: December 2017

Inspired by the first order numerical homogenization, we present a method for extracting continuous fluctuation fields from the Wang tile based compression of a material microstructure. The fluctuation fields are then used as enrichment basis in Extended Finite Element Method (XFEM) to reduce number of unknowns in problems with fully resolved microstructural geometry synthesized by means of the tiling concept. In addition, the XFEM basis functions are taken as reduced modes of a detailed discretization in order to circumvent the need for non-standard numerical quadratures. The methodology is illustrated with a scalar steady-state problem.
ON DEVELOPMENT OF THE INTERACTIVE DESIGN TOOL BASED ON ISOGEOMETRIC ANALYSIS
Authors: Dvořáková Edita , Patzák Bořek
Published: December 2017

Isogeometric analysis is a new concept of Finite element method which has been proposed to bridge the gap between the CAD systems and the FEM solvers. In Isogeometric analysis, the same basis functions, typically splines or NURBS, are used for geometry description as well as for approximation of unknowns and thus the same model can be shared between CAD and IGA systems. This results in a higher accuracy and overall efficiency of the analysis. Many isogeometric elements have been already proposed and implemented into the existing finite element solvers, but the automatic connection with a CAD system is usually missing. Our goal is to develop such a connection and to provide a tool which would interactively run the analysis when the model changes. This approach can enormously enhance the design process as it can provide the basic knowledge about the structural behavior already in conceptual design phase.
USING HOMOGENIZATION AND NANOINDENTATION FOR MICROFIBRIL ANGLE DETERMINATION OF SPRUCE
Authors: Kucíková Lucie , Hrbek Vladimír , Vorel Jan , Šejnoha Michal
Published: December 2017

This paper is concerned with the evaluation of microfibril angle of spruce. The microfibril angle is defined as an inclination of microfibrils from the longitudinal axis, the direction of lumens. It is well known and further supported by the present study that the microfibril angle has a great influence on the final mechanical properties of wood. This angle could be measured either directly using, e.g. polarisation microscopy, X-ray diffraction, infrared spectroscopy, or indirectly, as used in this study, by employing the nanoindentation measurements. Therein, the measured indentation modulus is compared with that obtained numerically using the anisotropic theory of indentation. The latter one depends on the entire stiffness matrix derived through homogenization and the searched microfibril angle. In view of the cell wall microstructure, the effective cell properties were found using the two-step micromechanical homogenization adopting both the Self-consistent and Mori-Tanaka methods.
ADAPTIVE QUASICONTINUUM SIMULATION OF ELASTIC-BRITTLE DISORDERED LATTICES
Authors: Mikeš Karel , Jirásek Milan
Published: December 2017

The quasicontinuum (QC) method is a computational technique that can efficiently handle atomistic lattices by combining continuum and atomistic approaches. In this work, the QC method is combined with an adaptive algorithm, to obtain correct predictions of crack trajectories in failure simulations. Numerical simulations of crack propagation in elastic-brittle disordered lattices are performed for a two-dimensional example. The obtained results are compared with the fully resolved particle model. It is shown that the adaptive QC simulation provides a significant reduction of the computational demand. At the same time, the macroscopic crack trajectories and the shape of the force-displacement diagram are very well captured.
LONG-TIME INVESTIGATION OF CEMENT COMPOSITE MATERIAL WITH MICRONIZED WASTE MARBLE POWDER: DYNAMIC MODULES
Authors: Prošek Zdeněk , Topič Jaroslav
Published: December 2017

This article focus on “blended cement”. The blended cement was created by using waste marble powder (WMP) as a partial replacement for cement. We investigated the influence of WMP on the developing of the dynamic modulus of elasticity and the dynamic shear modulus in time. Four different cement composites with WMP as a partial replacement for cement were studied (5, 10, 15 and 50 wt. %) together with reference samples. Dynamic modulus of elasticity was monitored during the first 377 days since manufacture by use of non-destructive testing (resonance method). The results showed that WMP in a small amount had a no effect on the dynamic modulus of elasticity and the dynamic shear modulus.
VARIATIONALLY-BASED EFFECTIVE DYNAMIC THICKNESS FOR LAMINATED GLASS BEAMS
Authors: Schmidt Jaroslav , Zemanová Alena , Janda Tomáš , Zeman Jan , Šejnoha Michal
Published: December 2017

Laminated glass, consisting of glass layers connected with transparent foils, has found its applications in civil, automotive, or marine engineering. Due to a high contrast in layer properties, mechanical response of laminated glass structures cannot be predicted using classical laminate theories. On the other hand, engineering applications demand easy-to-use formulas of acceptable accuracy. This contribution addresses such simplified models for free vibrations of laminated glass beams, with the goal to determine their natural frequencies and modal damping properties. Our strategy is to approximate the complex behavior of a laminated structure with that of an equivalent monolithic beam. Its effective thickness is determined by the variational method proposed by Galuppi and Royer-Carfagni for static problems, which we extended for modal analysis. We show that this new approach overcomes inaccuracies of the currently used dynamic effective thickness model by López-Aenlle and Pelayo.

Assessing the Reliability of Planktic Foraminifera Ba/Ca as a Proxy for Salinity off the Sunda Strait
Authors: Setiawan Riza Yuliratno , Wirasatriya Anindya , Shaari Hasrizal Bin , Setyobudi Eko , Rachman Faizal
Published: December 2017

The Ba/Ca ratio of planktic foraminifera carbonate serves as a new geochemical proxy for seawater Ba/Ca and thus providing information on modern and past salinity and freshwater discharge. In this study the applicability of Ba/Ca ratio of core-top Globigerinoides sacculifer collected off the eastern tropical Indian Ocean (ETIO) for paleoceanographic reconstructions was investigated. In doing so, we conducted a series of cleaning experiments for Ba/Ca extraction by using different reductive solutions. Our new results suggest that the Ba/Ca ratio of G. sacculifer cannot be utilized as a tracer for modern and past salinity changes in the ETIO region off the Sunda Strait. We suggest that the existence of seasonal upwelling adds an additional signal to the seawater Ba/Ca in the ETIO, and thus complicates the interpretation of G. sacculifer Ba/Ca as a freshwater tracer. Moreover, our cleaning experiment results show that the cleaning protocol of Mg/Ca, DTPA, and hydroxylamine can be used to extract valuable Ba/Ca ratios from planktic foraminifera tests. Keywords: G. sacculifer Ba/Ca, foraminifera cleaning experiments, the Sunda Strait.
Der erstaunliche methodologische Widerspruch zwischen Freuds Metapsychologie und seiner analytischen Technik
Authors: Detel Wolfgang
Published: December 2017

Freud’s metapsychology has been interpreted in a number of different ways. Some scholars see him committed to classical scientism, others to genuine hermeneutics. Many Freud philologists suggest that he moved from an early scientism to hermeneutic methods in his later writings, and some think he misunderstood his own angle, thinking himself to be a natural scientist, but actually practising hermeneutics. The article first looks at Freud’s model of the soul and his remarks about psychoanalytic explanations and concludes that there is overwhelming evidence for the contention that he conceived of psychoanalytic explanations in terms of causal explanations and that his metapsychology is, all things considered, scientistic. However, it seems that Freud did not clearly distinguish between causal and rational explanations (i. e. genuine interpretations). The article emphasizes that he could have found this distinction in the writings of Max Weber. In the last two sections, the article turns to a meticulous analysis of two vignettes describing Freud’s own treatment of two cases that he takes to be fine examples of the technique used in psychoanalytic treatment. It turns out that Freud himself looks at these cases and their treatment, throughout, in terms of rationality and irrationality. In particular, he seems to distinguish between an “external” irrationality and an “internal” rationality of neurotic diseases. He also seems to point to functions of neuroses representing certain solutions for mental disturbances. Thus, there is much evidence for assuming that in his psychoanalytic technique, Freud relied on genuine hermeneutic and functional methods; and therefore, Freud’s official metapsychology seems to be methodologically inconsistent with his analytic technique.

Effect of CeO2 on TiC Morphology in Ni-Based Composite Coating
Authors: Cai Yangchuan , Luo Zhen , Chen Yao
Published: December 2017

The TiC/Ni composite coating with different content of CeO2 was fabricated on the Cr12MoV steel by laser cladding. The microstructure of cladding layers with the different content of CeO2 from the bottom to the surface is columnar crystal, cellular crystal, and equiaxed crystal. When the content of CeO2 is 0 %, the cladding layer has a coarse and nonuniform microstructure and TiC particles gathering in the cladding layer, and then the wear resistance was reduced. Appropriate rare-earth elements refined and homogenised the microstructure and enhanced the content of carbides, precipitated TiC particles and original TiC particles were spheroidised and refined, the wear resistance of the cladding layer was improved significantly. Excessive rare-earth elements polluted the grain boundaries and made the excessive burning loss of TiC particles that reduced the wear resistance of the cladding layer.
Thomas Shadwell’s the Virtuoso as an Assemblage Laboratory. A View from Installation Art
Authors: Chaberski Mateusz
Published: December 2017

The contemporary landscape of performing arts becomes more and more populated by hybrid genres or “artistic installations” (Rebentisch) which fuse traditional artistic, theatrical and performance practices with scientific procedures, political activism and designing new technologies (e.g. bioart, technoart, digital art and site-specific performance). In this context, theatre texts can no longer be perceived as autopoietic means of solely artistic expression but become part of an assemblage of different discourses and practices. As contemporary assemblage theory contends (DeLanda), assemblages are relational entities which change dramatically depending on relations between its different human and nonhuman elements and various contexts in which they function.

Taking the contemporary installation art as a vantage point, this paper aims to analyse a Restoration comedy The Virtuoso (1676) by Thomas Shadwell in an assemblage of theatrical, scientific and political discourses and practices of Early Modern England. Staged in Dorset Gardens theatre in London, the play mobilised a plethora of discourses of science (the status of experimental philosophy institutionalized in 1660 as the Royal Society), politics (Restoration of the monarchy under Charles II) and gender (the infamous heac vir or effeminate man). Drawing on contemporary new materialism, the paper focuses predominantly on Shadwell’s use of the laboratory as a site of emerging assemblages rather than objective matters of fact. In this context, the play itself becomes an assemblage laboratory where new ways of thinking and being are being forged and constantly negotiated.
„Un champ de bataille on ne peut plus réel“. Zur Referentialität von Distanz und Nähe in 14 von Jean Echenoz
Authors: Schwarze Michael
Published: December 2017

This paper addresses the production of referentiality in historical fiction. It analyses Jean Echenoz’WorldWar I novel 14 (2012), by identifying textual patterns that generate effects of distance and proximity. These effects concern the metatextual dialogue the novel holds with conventional ways of representing this war, and they also relate to the actual historical past evoked by the novel. In this respect 14 performs a notable inversion. Historical fiction usually produces effects of distance in order to convey historical explanation and achieves historical concreteness by effects of proximity, whereas Echenoz endeavours to provide certain aspects of the war with explicative coherence, registering the material world with great concreteness. In many passages, on the other hand, his minimalist writing produces an ironic distance, which makes experiences of contingency aesthetically evident.

By considering ›characteristic‹ as a literary genre with specific features, this paper focuses on its pre- and early history in the Long Eighteenth Century. It starts with an overview of the current state of research, followed by a brief outline of the history of the concept, with special attention to the connections between philosophical and poetological discourses. Particular attention is devoted to the definitions of ›characteristic‹ given in essays and treatises on poetics of the 18
Zur Struktur und Rolle ästhetischer Erfahrung in Emil Staigers »Die Kunst der Interpretation« (1951)
Authors: Klauk Tobias , Köppe Tilmann
Published: December 2017

Current accounts of the aims and methods of criticism as developed in Emil Staiger’s seminal essay »Die Kunst der Interpretation« typically do not concentrate on the role of aesthetic experience. We clarify the notion of aesthetic experience employed in Staiger’s essay and point out the centrality of aesthetic experience for his view of criticism. According to Staiger, aesthetic experiences are central to the aesthetic merit of an artwork, they guide the critic’s appreciation of aesthetic properties, and literary criticism should be concerned with the elucidation of how aesthetic properties are based on other manifest properties of a work. We also review some recent alternative reconstructions of Staiger’s view, and offer some routes to a critique of his view that is based on his central assumptions concerning the aims and methods of criticism, rather than on a rejection of them.

A Role for Monomethylation of Histone H3-K27 in Gene Activity inDrosophila
Authors: Wang Liangjun , Joshi Preeti , Miller Ellen L , Higgins LeeAnn , Slattery Matthew , Simon Jeffrey A
Published: December 2017

N-terminal histone tails emanate from the chromatin fiber—providing docking surfaces for regulatory proteins—and are commonly modified by lysine methylation...

Polycomb repressive complex 2 (PRC2) is a conserved chromatin-modifying enzyme that methylates histone H3 on lysine-27 (K27). PRC2 can add one, two, or three methyl groups and the fully methylated product, H3-K27me3, is a hallmark of Polycomb-silenced chromatin. Less is known about functions of K27me1 and K27me2 and the dynamics of flux through these states. These modifications could serve mainly as intermediates to produce K27me3 or they could each convey distinct epigenetic information. To investigate this, we engineered a variant of Drosophila melanogaster PRC2 which is converted into a monomethyltransferase. A single substitution, F738Y, in the lysine-substrate binding pocket of the catalytic subunit, E(Z), creates an enzyme that retains robust K27 monomethylation but dramatically reduced di- and trimethylation. Overexpression of E(Z)-F738Y in fly cells triggers desilencing of Polycomb target genes significantly more than comparable overexpression of catalytically deficient E(Z), suggesting that H3-K27me1 contributes positively to gene activity. Consistent with this, normal genomic distribution of H3-K27me1 is enriched on actively transcribed Drosophila genes, with localization overlapping the active H3-K36me2/3 chromatin marks. Thus, distinct K27 methylation states link to either repression or activation depending upon the number of added methyl groups. If so, then H3-K27me1 deposition may involve alternative methyltransferases beyond PRC2, which is primarily repressive. Indeed, assays on fly embryos with PRC2 genetically inactivated, and on fly cells with PRC2 chemically inhibited, show that substantial H3-K27me1 accumulates independently of PRC2. These findings imply distinct roles for K27me1 vs. K27me3 in transcriptional control and an expanded machinery for methylating H3-K27.

The aim of this study was to evaluate the effect of essential oil (EO) from fresh leaves of Mentha piperita L. on the conservation of mango puree during storage. The results of physicochemical characterization of mango puree underlined its high nutritional potential, with carbohydrates, carotenoids and vitamin C contents of 9.5±0.4%, 20.05±0.03 mg/100g and 21.03±0.05 mg/100g respectively. Microbiological analyses revealed that Aspergillus and Mucor were the most common genera of fungi identified from mango puree in Benin by using a taxonomic schemes primarily based on morphological characters of mycelium and conidia. The isolated fungi include Aspergillus parasiticus, A. versicolor and Mucor spp. Antifungal assay, performed by the agar diffusion assay, indicated that essential oil exhibited high antifungal activity against the growth of fungi. The minimal inhibitory concentration (MIC) of the essential oil was found to be 2.0 μL.mL-1for A. parasiticus and A. versicolor; and 1.0 μL.mL-1 for Mucor spp. The Minimal Fungicide Concentration (MFC)was recorded to be 2.5 μL.mL-1 for A. parasiticus and A. versicolor; and 1.5 μL.mL-1 for Mucor spp. Chemical analysis by GC/MS of the oil led to the identification of 15 components, characterized by menthol (46.7%), neomenthol (8.28%) and 1.8-cinéole (6.49%) as major components. Results obtained during the evaluation of the physicochemical characteristics of the mango puree stored by adding EO, indicated a significant decrease in the pH, carotenoids and vitamin C contents. However, with EO concentration of 2.5 μL.mL-1, the pH of stored mango puree was 6.4±0.7 after 15 days of preservation, with a high carotenoids and vitamin C contents of 19.02±0.07 mg/100g and 21.01±0.03 mg/100g. The EO of Mentha piperita L., with high antimicrobial property, offers a novel approach to the management of fruits derivate products during storage.

Actinomycetes are one of the most important groups that produce useful secondary metabolites. They play a great role in pharmaceutical and industrial uses. The search for antibiotic producing soil actinomycetes to inhibit the growth of pathogenic microorganisms has become widespread due to the need for newer antibiotics. The present work was aimed to isolate soil actinomycetes from pinus tree rhizosphere from Doddabetta, Western Ghats, Tamil Nadu, India. Thirty one actinomycetes were isolated based on heterogeneity and stability in subculturing; they were screened against 5 Gram positive and 7 Gram negative bacteria in an in vitro antagonism assay. In the preliminary screening, out of 31 isolates, 12.09% showed good antagonistic activity; 25.08% showed moderate activity; 19.35% showed weak activity and 41.93% showed no activity against the tested bacteria. Among the isolates tested, DPR20 showed good antibacterial activity against both Gram positive and Gram negative bacteria. The antibacterial crude secondary metabolites were extracted using ethyl acetate from micromonospora medium (M3) in which DPR20 was grown for twelve days at 30ºC. The lowest MIC value of ethyl acetate extract against Bacillus subtilis and Staphylococcus epidermis was 31.25µg/ml. The active isolate was identified as Streptomyces collinus DPR20 based on morphology, physiology, scanning electron microscopy and 16S rRNA gene sequence analysis.
Comparison of two infrastructure project implementation models in a developing country
Authors: Laryea Samuel , Watermeyer Ronald B
Published: December 2017

A comparative analysis of public sector infrastructure projects implemented using a traditional public sector model against projects implemented using a modern management contractor model is presented. Traditionally, the implementation of public sector construction projects in South Africa is undertaken by an implementer such as the Department of Public Works. However, in 2014, the Western Cape Education Department created a framework contract and employed two management contractors with single-point accountability to implement maintenance and upgrading projects alongside those implemented in the traditional manner. A total of 122 projects implemented by management contractors are evaluated and compared with 35 implemented by the Western Cape Department of Transport and Public Works based on the cost performance, time performance and professional services costs of the two approaches. The practice of including contingency and provisional sums in contracts distorts the cost performance analysis, and superficial comparisons can be misleading. The management contracts delivered more projects on time. The professional services costs associated with management contracts was 9·2% compared to 15·6% for public works projects. The overall evidence demonstrates that the management contracting system is efficient and suited to the nature of maintenance and upgrading projects and delivers significant advantages.
Investor Concentration, Flows, and Cash Holdings: Evidence from Hedge Funds
Authors: Kruttli Mathias S. , Monin Phillip J. , Watugala Sumudu W.

We show that when only a few investors own a substantial portion of a hedge fund&#x27;s net asset value, flow volatility increases because investors&#x27; exogenous, idiosyncratic liquidity shocks are not diversified away. Using confidential regulatory filings, we confirm that high investor concentration hedge funds experience more volatile flows. These hedge funds hold more cash and liquid assets, which help absorb large, unexpected outflows. Such funds have to pay a liquidity premium and generate lower risk-adjusted returns. Investor concentration does not affect flow-performance sensitivity. These results are robust to including lock-up and redemption periods, strategy, manager ownership, and other controls.
La Mercantilización de la Educación Superior en Colombia
Authors: García Mazo Claudia María
Published: December 2017

Objetivo: El fin de este trabajo es mostrar los efectos pro y en contra de la educación superior colombiana al ser tratada como una mercancía.Método: Se presenta una revisión de aportes al tema de autores como Rodríguez (2005), Aboites (2007) Ruiz (2009) entre otros. “La Educación Superior en las Negociaciones Internacionales”,“Acuerdo General sobre el Comercio de Servicios (GATS) y la Educación Superior”,   “Aspectos básicos de la Educación Superior en Colombia”,  “TLC Colombia-Estados Unidos y la Educación Superior”,  “La experiencia educativa a nivel internacional”.Resultados: Al analizar el sector de la educación en países como Gran Bretaña, Estados Unidos, Australia, Alemania, se observa que es dinámico e importante por ser una actividad que reporta ganancias económicas. En países emergentes como Colombia dominado por una política proteccionista, han abierto sus economías para integrarse a la economía mundial. Para  cumplir en el sector de la educación con este proceso de globalización se promulgó la Ley 30 de 1992.Conclusiones: La educación superior al ser considerada como un servicio,  reporta altas ganancias económicas y proliferación de instituciones de dudosa calidad, por lo que el Gobierno debe estar atento y ser más riguroso en su regulación.

Background. The leaves of many species of Maytenus are used to prepare herbal drugs to treat stomach ulcers.
Questions. In order to define key anatomical characters for the unambiguous species identification, the present study aimed to describe the leaf morphoanatomy of M. imbricata.
Species study. Maytenus imbricata Mart. ex Reissek (Celastraceae)
Study site and dates. Collected in an area of ‘campo rupestre’ - one of the Brazilian Savannah vegetation (20º22’11.02”S, 43º30’22.81”W) in August 2015.
Methods. The plant material was processed according to commonly used techniques in plant anatomy studies.
Results. The major anatomical characters for several species of Maytenus identification also present in M. imbricata are marginal teeth, conspicuous epicuticular wax, ciclocytic stomata, thick external periclinal wall with large pits on epidermal cells and vascular system with a closed loop shape in cross-section. Strips on the anticlinal walls on epidermal cells and conspicuous gelatinous fibers sheath are diagnostic for M. imbricata.
Conclusions. Strips on the anticlinal wall of the epidermal cell are reported for the first time for the genus. These xeromorphic traits help the species to survive in arid environments and may contribute to quality control of the raw material used in the production of herbal medicines.
Naturaleza del fenómeno contractual electrónico desde una perspectiva documental: un lastre heredado
Authors: Rodríguez Ayuso Juan Francisco
Published: December 2017

El objetivo principal del presente trabajo consiste en ofrecer un análisis sistemático de la aplicación de las modernas tecnologías de la información y de la comunicación en los procedimientos de contratación electrónica y en los medios de prueba derivados del incumplimiento de las obligaciones contraídas al amparo de la misma. En concreto, se exponen sintetizadamente las principales posturas existentes en torno a la consideración del documento electrónico como medio de prueba y una propuesta de lege ferenda que contemple el contrato electrónico como auténtica prueba documental, subsanando la antinomia legislativa existente entre la ley procesal civil y la regulatoria de los servicios de la sociedad de la información. Por último, se expone cómo el principio de equivalencia funcional trata de subsanar este error heredado merced a una más que discutida redacción.
