THE IMPACT OF ESG FACTORS ON MARKET VALUE OF COMPANIES FROM TRAVEL AND TOURISM INDUSTRY
Authors: Ionescu George H. , Firoiu Daniela , Pirvu Ramona , Vilag Ruxandra Dana
Published: May 2019

The aim of this paper is to investigate the relationship between environmental, social, and governance (ESG) factors and firm market value for the companies from travel and tourism industry and, in the same time, to investigates the question if the association between good ESG scores for travel and tourism companies and their market value can be used as a performance predictor. The impact of extra-financial ESG performance on market value of the companies was estimated using the modified version of the Ohlson (1995) model, based on a sample of 73 listed companies, worldwide distributed, during the 2010–2015 period. The overall results of this research are consistent with the value enhancing theory (as opposed with the shareholder expense theory). From the ESG factors, the governance factor seems to have the most important influence on the market value of the selected companies, regardless of the geographic region where they are located. Thus, our findings provide new insights into the influence of each ESG factor on the market value of the companies, providing a useful tool for stakeholders to measure economic impact but also for use as a predictor of economic performance.
Constraining Massive Star Activities in the Final Years through Properties of Supernovae and Their Progenitors
Authors: Ouchi Ryoma , Maeda Keiichi
Published: May 2019

Recent observations of supernovae (SNe) just after the explosion suggest that a good fraction of SNe have the confined circumstellar material (CSM) in the vicinity, and the pre-SN enhanced mass loss may be a common property. The physical mechanism of this phenomenon is still unclarified, and the energy deposition into the envelope has been proposed as a possible cause of the confined CSM. In this work, we have calculated the response of the envelope to various types of sustained energy deposition starting from a few years before the core collapse. We have further investigated how the resulting progenitor structure would affect the appearance of the ensuing supernova. While it has been suspected that a super-Eddington energy deposition may lead to a strong and/or eruptive mass loss to account for the confined CSM, we have found that a highly super-Eddington energy injection into the envelope changes the structure of the progenitor star substantially, and the properties of the resulting SNe become inconsistent with typical SNe. This argument constrains the energy budget involved in the possible stellar activity in the final years to be at most one order of magnitude higher than the Eddington luminosity. Such an energy generation, however, would not dynamically develop a strong wind on a timescale of a few years. We therefore propose that a secondary effect (e.g., pulsation or binary interaction) triggered by moderate envelope inflation, which is caused by sub-Eddington energy injection, likely induces the mass loss.
Inverse Compton Scattering Spectra of Gamma-Ray Burst Prompt Emission
Authors: Zhang Yue , Geng Jin-Jun , Huang Yong-Feng
Published: May 2019

Although the physical origin of gamma-ray burst (GRB) prompt emission is still controversial, synchrotron radiation from accelerated electrons is a promising mechanism. It is believed that electrons are accelerated continuously by ultra-relativistic shocks or magnetic reconnections. At the same time, these electrons will be cooled via several processes (mainly adiabatic expansion, synchrotron radiation, and inverse Compton scattering (ICS)), which regulate the distribution of electrons. An extra high-energy spectrum component is expected to be induced by ICS. However, the gamma–gamma annihilation effect may eliminate the high-energy photons and prevent the observers from distinguishing the extra component. We perform numerical calculations by taking these effects into account and discuss whether the extra ICS component could be observed. By exploring the plausible parameter space for relevant quantities of the GRB ejecta, we present the electron distributions and the corresponding spectra of synchrotron radiation and ICS. It is found that the extra component is observable only for ejecta with a rather large bulk Lorentz factor. A large Lorentz factor means the adiabatic expansion is the leading process in the electron cooling procedure, which makes the low-energy electron distribution spectrum relatively hard. Therefore, the ICS component is more likely to be detected for GRBs that have a hard low-energy photon spectrum.
Constraining the Neutron Star Radius with Joint Gravitational-wave and Short Gamma-Ray Burst Observations of Neutron Star–Black Hole Coalescing Binaries
Authors: Ascenzi Stefano , Lillo Nicola De , Haster Carl-Johan , Ohme Frank , Pannarale Francesco
Published: May 2019

Coalescing neutron star (NS)–black hole (BH) binaries are promising sources of gravitational-waves (GWs) that are predicted to be detected within the next few years by current GW observatories. If the NS is tidally disrupted outside the BH innermost stable circular orbit, an accretion torus may form, and this could eventually power a short gamma-ray burst (SGRB). The observation of an SGRB in coincidence with gravitational radiation from an NS–BH coalescence would confirm the association between the two phenomena and also give us new insights into NS physics. We present here a new method to measure NS radii and thus constrain the NS equation of state using joint SGRB and GW observations of NS–BH mergers. We show that in the event of a joint detection with a realistic GW signal-to-noise ratio of 10, the NS radius can be constrained to ≲20% accuracy at 90% confidence.
Gravitational-wave Merging Events from the Dynamics of Stellar-mass Binary Black Holes around the Massive Black Hole in a Galactic Nucleus
Authors: Zhang Fupeng , Shao Lijing , Zhu Weishan
Published: May 2019

We study the dynamical evolution of the stellar-mass binary black holes (BBHs) in a galactic nucleus that contains a massive black hole (MBH). For a comprehensive study of their merging events, we consider simultaneously the nonresonant and resonant relaxations of the BBHs, the binary–single encounters of the BBHs with the field stars, the Kozai–Lidov (KL) oscillation, and the close encounters between the BBHs and the central MBH, which usually lead to binaries’ tidal disruptions. As the BBHs are usually heavier than the background stars, they sink to the center by mass segregation, making the KL oscillation an important effect in merging BBHs. The binary–single encounters can not only lead to softening and ionization of the BBHs but also make them harden, which increases the merging rates significantly. The mergers of BBHs are mainly contributed by galaxies containing MBHs less massive than 108

, and the total event rates are likely on order of 1–10 Gpc−3 yr−1, depending on the detailed assumptions of the nucleus clusters. About 3%–10% of these BBH mergers are with eccentricity ≥0.01 when their gravitational-wave oscillating frequencies enter the LIGO band (10 Hz). Our results show that merging the BBHs within galactic nuclei can be an important source of the merging events detected by the Advanced LIGO/Virgo detectors, and they can be distinguished from BBH mergers from the galactic fields and globular clusters when enough events are accumulated.
Direct Observations of Traveling Ionospheric Disturbances as Focusers of Solar Radiation: Spectral Caustics

Published: May 2019

The solar radiation focusing effect is related to the specific phenomenon of propagation of the Sun-emitted HF and VHF waves through terrestrial ionosphere. This natural effect is observed with ground-based radio instruments running within the 10–200 MHz range as distinctive patterns—the spectral caustics (SCs)—on the solar dynamic spectra. It has been suggested that SCs are associated with medium-scale traveling ionospheric disturbances (MSTIDs). In this paper, we present the first direct observations of SCs induced by MSTIDs, using solar dynamic spectra with SCs obtained by different European radio telescopes on 2014 January 8 and simultaneous two-dimensional detrended total electron content (dTEC) maps over Europe. Spatial examination of dTEC maps as well as precise timing analysis of the maps and the dynamic spectra have been performed. First, we found several pairs of one-to-one (TID-SC) correspondences. The study provides strong observational evidence supporting the suggestion that MSTIDs are the cause of SCs.
Galactic Stellar Populations from Photometric Metallicity Distribution Functions
Authors: Gu Jiayin , Du Cuihua , Zuo Wenbo
Published: May 2019

Based on Sloan Digital Sky Survey photometric data, Gu developed a new Monte-Carlo-based method for estimating the stellar metallicity distribution functions (MDFs). This method enables a more reliable determination of MDFs compared with the conventional polynomial-based methods. In this work, MDF determined from the method are well fit by a three-Gaussian model, with peaks at [Fe/H] = −0.68, −1.38, and −1.90, associated with the thick disk, the inner halo, and the outer halo, respectively. The vertical metallicity gradient within 1 < Z < 5 kpc is

around R = 8.25 kpc. But the mean radial gradient is almost negligible. The density profile of the thick disk is fitted with a modified double exponential law decaying to a constant at far distance. The scale height and scale length thus estimated are H ≈ 1.13 kpc and L ≈ 3.63 kpc, which are consistent with the results determined from star-count methods in previous studies. The halos are described with a two-axial power-law ellipsoid, and the axis ratios of both the inner halo and the outer halo, inferred from stellar number density in the R–Z plane, are q
ih ≈ 0.49 and q
oh ≈ 0.61, respectively. It also manifests that the outer halo is more spherical than the inner halo. Moreover, the halo power-law indices estimated are n
ih ≈ 3.4 and n
oh ≈ 3.1, indicating that the stellar number density of the inner halo changes more steeply than that of outer halo.
The Anomalously Low (Sub)Millimeter Spectral Indices of Some Protoplanetary Disks May Be Explained By Dust Self-scattering
Authors: Liu Hauyu Baobab
Published: May 2019

Previous (sub)millimeter observations have found that the spectral indices of dust emission from some young stellar objects are lower than that of the blackbody emission in the Rayleigh–Jeans limit (i.e., 2.0). In particular, the recent Atacama Large Millimeter Array observations have spatially resolved that the innermost regions of the protoplanetary disks TW Hya and HD 163296 present anomalously low (i.e., <2.0) millimeter spectral indices. In some previous works, such anomalously low millimeter spectral indices were considered unphysical and were attributed to measurement errors. The present work clarifies that if the albedo is high and is increasing with frequency, it is possible to reproduce such anomalously low spectral indices when the emission source is optically thick. In addition, to yield lower than 2.0 spectral index at (sub)millimeter bands, the required dust maximum grain size a
max is on the order of 10–100 μm, which is consistent with the previously derived a
max values based on multiwavelength dust polarimetric observations. In light of this, measuring the Stokes I spectral index may also serve as an auxiliary approach for assessing whether the observed dust polarization is mainly due to dust scattering or to the aligned dust grains.

Reflexões sobre o caráter ambíguo e controverso da tecnologia
Authors: Lenzi Letícia
Published: May 2019

Neste artigo sugerem-se algumas reflexões para o trabalho filosófico da tecnologia, tema que foi, tradicionalmente, polarizado entre a análise de pensadores otimistas e confiantes no poder da tecnologia em aperfeiçoar a vida humana, e a crítica de humanistas que procuraram denunciar seu lado destrutivo. A índole ambígua e controversa da tecnologia é expressa na filosofia de dois autores que representam tendências distintas de análise. De um lado a filosofia analítica de Mario Bunge, que ressalta o papel emancipador da racionalidade técnica para a vida humana, e de outro a hermenêutica de Lewis Mumford, que busca esclarecer os aspectos problemáticos da sociedade tecnológica moderna. O confronto entre suas teses permite o destaque da ambiguidade como característica fundamental da tecnologia, importante para o tratamento filosófico da mesma, já que cada enfoque, ao destacar aspectos distintos sobre um mesmo fenômeno, pode sugerir conclusões diversas e até contraditórias.
Morphometrics and phylogeography of the cave-obligate land snail Helicodiscus barri (Gastropoda, Stylommatophora, Helicodiscidae)
Authors: Gladstone Nicholas S. , Niemiller Matthew L. , Pieper Evelyn B. , Dooley Katherine E. , McKinney Michael L.
Published: May 2019

Molecular studies have recently led to the detection of many cryptic species complexes within morphologically ambiguous species formerly undescribed by the scientific community. Organisms such as land snails are at a particularly higher risk of species misidentification and misinterpretation, in that gastropod systematics are based almost entirely on external shell morphology. Subterranean ecosystems are associated with especially high degrees of cryptic speciation, largely owing to the abiotic similarities of these systems. In this study, we attempt to diagnose the potential cryptic diversity in the troglobitic land snailHelicodiscusbarri. Land snails are generally associated with having low vagility, and as such this species’ broad, mosaic distribution indicates the misdiagnosis of this organism as a single species. We analyze both mitochondrial (16S, CO1) and nuclear (28S, H3) genetic data for 23 populations. Phylogeny forH.barriwas reconstructed using both maximum-likelihood and Bayesian approaches to assess relationships among populations, and two species delimitation methods (mPTP and ABGD) were used to detect the presence of unique molecular operational taxonomic units (MOTUs). Species delimitation results revealed seven and sixteen MOTUs respectively, suggesting the presence of several cryptic lineages withinH.barri. To assess how external shell morphology corresponds with patterns of genetic and environmental variation, two morphometric approaches were used incorporating 115 shells from 31 populations. Both morphometric approaches reveal a significant environmental influence on shell morphology, and one approach showed the significance of MOTU groups. We discuss the delimitation and morphometric results and additionally provide discussion on the taxonomic and conservation implications of this study.

Objetivou-se classificar e estimar os fatores associados ao risco gestacional em mulheres atendidas para o parto pelo Sistema Único de Saúde (SUS). Estudo transversal com entrevista e consulta ao cartão da gestante e ao prontuário hospitalar de 607 puérperas residentes em município do Estado do Paraná, Brasil. O risco gestacional foi classificado segundo critérios do programa Rede Mãe Paranaense - RMP e a associação com características maternas foi realizada por meio de análise de regressão logística. Das puérperas, 50,9% tiveram gravidez classificada como de risco habitual, 5,8% risco intermediário e 43,3% alto risco. Para classificação do risco, o tabagismo (12,7%), a raça negra (11,4%), os distúrbios hipertensivos (9,6%) e a infecção do trato urinário de repetição (8,4%) foram as condições mais frequentes. A reação paterna negativa à gestação (ORaj=1,71), o IMC pré-gestacional elevado (ORaj=1,67) e ter tido duas ou mais gestações anteriores (ORaj=1,85) foram independentemente associados ao alto risco gestacional. Para prevenir complicações na gestação, a equipe de saúde deve considerar os fatores modificáveis, como o tabagismo, hipertensão, infecção de trato urinário e também não modificáveis, como raça/cor negra, história de IMC pré-gestacional elevado e reação negativa do pai da criança à gestação.

Investigation on the Tensile Behavior of Graphene-Aluminum Nano-Laminated Composites by Molecular Dynamics Simulation
Authors: Zhu Jia Qi , Yang Qing Sheng , Liu Xia
Published: May 2019

Graphene-aluminum (Gr/Al) composite laminated by aluminum (Al) and graphene sheets alternately has excellent mechanical properties thanks to the high strength, high Young’s modulus and the two-dimensional atomic structure of graphene. In this study, the uniaxial tensile properties of Gr/Al nano-laminated composite are studied by molecular dynamics (MD) method. It is found that the thickness of Al layer has a significant effect on the tensile strength and Yang’s modulus of the Gr/Al composite. Composite with a smaller thickness of Al layer shows better properties. Graphene not only block propagation of dislocations, but bear most of the loads, resulting in higher Young's modulus, tensile strength and failure strain of the composites than those of pure Al. The simulation of temperature-effect shows that the Gr/Al composite is difficult to arise plastic deformation at low temperature, which lead to a higher strength and modulus of the composite. In addition, the effect of graphene stacking on the properties of composites is investigated. Through tensile tests at the vertical and parallel interfaces, it is found that graphene stacking may lead to a reduced performance of the composite.

Published: May 2019

A soft actuator is expected to be applied in the next generation of robotics. This study focuses on soft gel actuators hybridized with nanosheet liquid crystals. The resulting soft actuator has a highly hydrophilic property, and is suitable for underwater use. When the gel in water is heated to more than the transition temperature, the gel contracts; conversely, it swells when it is cooled. This gel actuator remarkably has an anisotropic contraction characteristic because the orientation of the nanosheets is uniformly arranged. However, little is known about its dynamic characteristics of the thermal contraction. As a basic analysis, this paper investigates the heating step response through experiments, and reveals the variation of the time constant against the dimensions.

Published: May 2019

In recent years, global warming is a serious international problem. We focused on dielectric elastomer power generation to solve the problem. The dielectric elastomer generation has characteristics such as compactness and flexibility. The dielectric elastomer generation can harvest electric energy from renewable energy sources such as sea wave, wind, and human motion. However, the dielectric elastomer generation has a weakness dependent on an external power supply. In this paper, we proposed a self-excited dielectric elastomer generation circuit using piezoelectric elements. As a circuit verification method, circuit simulations are performed using MATLAB / Simulink, and the circuit behavior is confirmed from the results. From results, it is considered that dielectric elastomer generation can be performed without using the external power supply.
Implication of strongly increased atmospheric methane concentrations for chemistry–climate connections
Authors: Winterstein Franziska , Tanalski Fabian , Jöckel Patrick , Dameris Martin , Ponater Michael
Published: May 2019

Abstract. Methane (CH4) is the second-most important directly emitted
greenhouse gas, the
atmospheric concentration of which is influenced by human activities. In
this study, numerical simulations with the chemistry–climate model (CCM) EMAC are
performed, aiming to assess possible consequences of significantly enhanced CH4
concentrations in the Earth's atmosphere for the climate. We analyse experiments with 2×CH4 and 5×CH4 present-day (2010)
mixing ratio and its quasi-instantaneous chemical impact on the
atmosphere. The massive increase in CH4 strongly influences the
tropospheric chemistry by reducing the OH abundance and thereby
extending the CH4 lifetime as well as the residence time of other
chemical substances. The region above the tropopause is impacted by a
substantial rise in stratospheric water vapour (SWV). The stratospheric
ozone (O3) column increases
overall, but SWV-induced stratospheric cooling also leads to a
enhanced ozone depletion in the Antarctic lower stratosphere. Regional
patterns of ozone change are affected by modification of stratospheric
dynamics, i.e. increased tropical upwelling and stronger meridional transport
towards the polar regions. We calculate the net radiative impact (RI) of the
2×CH4 experiment to be 0.69 W m−2, and for the
5×CH4 experiment to be 1.79 W m−2. A substantial part of the
RH is contributed by chemically induced O3 and SWV
changes, in line with previous radiative forcing estimates. To our knowledge this is the first numerical study using a CCM with
respect to 2- and 5-fold CH4 concentrations and it is therefore
an overdue analysis as it emphasizes the impact of possible strong future
CH4 emissions on atmospheric chemistry and its feedback on climate.
Geomorphic signatures of the transient fluvial response to tilting
Authors: Beeson Helen W. , McCoy Scott W.
Published: May 2019

Abstract. Nonuniform rock uplift in the form of tilting has been documented in convergent margins, postorogenic landscapes, and extensional provinces. Despite the prevalence of tilting, the transient fluvial response to tilting has not been quantified such that tectonic histories involving tilt can be extracted from river network forms. We used numerical landscape evolution models to characterize the transient erosional response of a river network initially at equilibrium to a punctuated rigid-block tilting event. Using a model river network composed of linked 1-D river longitudinal profile evolution models, we show that the transient response to punctuated tilting creates characteristic forms or geomorphic signatures in mainstem and tributary profiles that are distinct from those generated by other perturbations such as a step change in uniform rock uplift rate or major truncation of headwater drainage area that push a river network away from equilibrium. These signatures include 1) a knickpoint in the mainstem that separates a downstream profile with uniform steepness (i.e., channel gradient normalized for drainage area) from an upstream profile with nonuniform steepness, with the mainstem above the knickpoint more out of equilibrium than the tributaries following forward tilting towards the outlet, versus the mainstem less out of equilibrium than the tributaries following back tilting towards the headwaters; 2) a pattern of mainstem incision below paleotopography markers that increases linearly up to the mainstem knickpoint, or vice-versa following back tilting; and 3) tributary knickzones with nonuniform steepness that mirrors that of the mainstem upstream of the slope-break knickpoint. Immediately after tilting, knickpoints form at the mainstem outlet and each mainstem-tributary junction. Time since tilting onset is recorded by mainstem knickpoint location relative to base level and by the upstream end of tributary knickzones relative to tributary-mainstem junctions. Tilt magnitude is recorded in the spatial gradient of mainstem incision depth and, in the forward tilting case, by tributary knickzone drop height. Heterogeneous lithology can modulate the transient response to tilting and, post-tilt, knickpoints can form anywhere in a stream network where more erodible rock occurs upstream of less erodible rock. With a full 2-D model, we show that stream segments flowing in the tilt direction have elevated channel gradient during the transient and that the magnitude of tilt can be recovered from the relationship between channel gradient and azimuth, but only shortly after tilting. Tilting is also reflected in network topologic changes via stream capture oriented in the direction of tilt. As an example of how these geomorphic signatures can be used in concert to estimate timing and magnitude of a tilting event, we show a sample of rivers draining the west slope of the Sierra Nevada, California, USA, a range long thought to have been tilted westward towards river outlets in the late Cenozoic.

Abstract. A new feed-forward neural network (FFNN) model is presented to reconstruct surface ocean partial pressure of carbon dioxide (pCO2) over the
global ocean. The model consists of two steps: (1) the reconstruction of
pCO2 climatology, and (2) the reconstruction of
pCO2 anomalies with respect to the climatology. For the
first step, a gridded climatology was used as the target, along with sea
surface salinity (SSS), sea surface temperature (SST), sea surface height
(SSH), chlorophyll a (Chl a), mixed layer depth (MLD), as well as latitude and longitude as
predictors. For the second step, data from the Surface Ocean CO2
Atlas (SOCAT) provided the target. The same set of predictors was used during
step (2) augmented by their anomalies. During each step, the FFNN model
reconstructs the nonlinear relationships between pCO2 and
the ocean predictors. It provides monthly surface ocean pCO2
distributions on a 1∘×1∘ grid for the period from
2001 to 2016. Global ocean pCO2 was reconstructed with
satisfying accuracy compared with independent observational data from SOCAT.
However, errors were larger in regions with poor data coverage (e.g., the
Indian Ocean, the Southern Ocean and the subpolar Pacific). The model
captured the strong interannual variability of surface ocean
pCO2 with reasonable skill over the equatorial Pacific
associated with ENSO (the El Niño–Southern Oscillation). Our model was
compared to three pCO2 mapping methods that participated in
the Surface Ocean pCO2 Mapping intercomparison (SOCOM)
initiative. We found a good agreement in seasonal and interannual variability
between the models over the global ocean. However, important differences
still exist at the regional scale, especially in the Southern Hemisphere and,
in particular, in the southern Pacific and the Indian Ocean, as these regions
suffer from poor data coverage. Large regional uncertainties in reconstructed
surface ocean pCO2 and sea–air CO2 fluxes have a
strong influence on global estimates of CO2 fluxes and trends.

Abstract. Interactive motion planing and collaborative positioning will play a key role in future autonomous driving applications. For this purpose, the precise reconstruction and pose estimation of other traffic participants, especially of other vehicles, is a fundamental task and will be tackled in this paper based on street level stereo images obtained from a moving vehicle. We learn a shape prior, consisting of vehicle geometry and appearance features, and we fit a vehicle model to initially detected vehicles. This is achieved by minimising an energy function, jointly incorporating 3D and 2D information to infer the model’s optimal and precise pose parameters. For evaluation we use the object detection and orientation benchmark of the KITTI dataset (Geiger et al., 2012). We can show a significant benefit of each of the individual energy terms of the overall objective function. We achieve good results with up to 94.8% correct and precise pose estimations with an average absolute error smaller than 3° for the orientation and 33 cm for position.
FACADE RECONSTRUCTION FOR TEXTURED LOD2 CITYGML MODELS BASED ON DEEP LEARNING AND MIXED INTEGER LINEAR PROGRAMMING
Authors: Hensel S. , Goebbels S. , Kada M.
Published: May 2019

Abstract. The paper describes a workflow for generating LoD3 CityGML models (i.e. semantic building models with structured facades) based on textured LoD2 CityGML models by adding window and door objects. For each wall texture, bounding boxes of windows and doors are detected using “Faster R-CNN”, a deep neural network. We evaluate results for textures with different resolutions on the ICG Graz50 facade dataset. In general, detected bounding boxes match very well with the rectangular shape of most wall openings. Thus, no further classification of shapes is required. Windows are typically aligned to rows and columns, and only a few different types of windows exist for each facade. However, the neural network proposes rectangles of varying sizes, which are not always aligned perfectly. Thus, we use post-processing to obtain a more realistic appearance of facades. Window and door rectangles get aligned by solving a mixed integer linear optimization problem, which automatically leads to a clustering of these openings into few different classes of window and door types. Furthermore, an a-priori knowledge about the number of clusters is not required.

New taxonomic proposal for Chinese phraseology
Authors: Chunyi 雷春仪 Lei
Published: May 2019

Over the years, the taxonomy of Chinese phraseology has been controversial. One of the main challenges for research in the field of phraseology is to discover how to classify all of the phraseological units in a logical and objective way. Based on the concept of grammatical metaphor (Pamies 2014, 2017), this paper tries to prove that a new taxonomy, more similar to the “Western” tradition, with the criteria of fixedness, idiomaticity and multilexematicity could be applied to the Chinese phraseology. Firstly, we examine the terminological problems in the Chinese phraseology and explain the function of metaphor in phraseology. Secondly, we demonstrate how this new taxonomy is applied to all the categories of Chinese phraseology, offering new terminology and definitions for each category. Thirdly, we focus on the slight taxonomic differences regarding phraseology between Chinese and Romanic/Germanic languages. Hopefully the application of this new taxonomy to Chinese phraseology can facilitate an objective comparison with other languages.
Análisis contrastivo de los diminutivos en español y en chino
Authors: Zuo左雅 Ya
Published: May 2019

Este trabajo está destinado a la comparación del sufijo diminutivo en español y en chino, cuya exposición se presenta estructurada en cinco partes. En la primera se describen las características de tales sufijos, sus respectivas restricciones morfofonológicas y semánticas, y sus incompatibilidades con algunas bases. En la segunda, se hace referencia a sus funciones pragmáticas (su grado de la familiaridad, de cortesía, su uso para la intensificación o la rebaja de la emoción), y gramaticales, fundamentalmente su capacidad de cambiar, en ciertos casos, la categoría léxica de la base. La tercera parte fija su atención en la lexicalización de algunas formaciones diminutivas, para dar cuenta de las razones y consecuencias de este proceso y de su productividad. En la cuarta parte se atiende al diminutivo de ambas lenguas desde el punto de vista cognitivo, relacionando su valor semántico ‘tamaño pequeño’ con sus funciones semánticas y pragmáticas mediante la teoría del prototipo, la metáfora conceptual y la metonimia. Por último, con los datos proporcionados por nuestro análisis, se proponen algunas consideraciones didácticas para la enseñanza de los diminutivos a alumnos chinos.

Authors: Cuervo Maria Rita Macedo , Hamann Cristiano , Pizzinato Adolfo
Published: May 2019

Este estudo procura compreender aspectos qualitativos do funcionamento de uma feira agroecológica em Porto Alegre, a partir da noção Comunidades de Prática. Além de observação participante durante quatro anos foram realizadas dezenove entrevistas, entre produtores(as) e consumidores(as), de modo a construir uma rede de temas recorrentes e apreensões qualitativas que permitem compreensões acerca das relações estabelecidas. Despontam três aspectos na formação desta Comunidade: a associação do alimento orgânico com saúde; a agroecologia como produção e consumo político; a confiança, sociabilidade e transgeracionalidade como aspectos relacionais distintivos. Os atores sociais assumem posições num discurso ambientalista que envolve alternativas à produção agroindustrial, dando ensejo para formas de resistência política que despontam na construção de uma rede dialógica de negociação comercial e sociabilidade.
Effect of plant growth regulators on biochemical compounds of tangerine (Citrus unshiu Marc.)
Authors: Belous Oksana , Abilphazova Julia
Published: May 2019

We investigated the effect on tangerine of new generation plant growth regulators. The use of drugs in the period of fruit ripening has led to increased 2.0 - 3.7 times abscisic acid (AA) and 1.9 - 4.7% of Indole-acetic acid (IAA) acid in the leaves. Studies have shown that Indole-acetic acid and abscisic acid beginning of a sharp accumulation of their hormones coincides with action of stress factors and growth dormancy period. The use of the regulators had an impact not only on their content in leaves but also on fruit quality. For example, treatment Indole-acetic acid and Obstaktin led to an increase in the fruit of vitamin C. After treatments with plant growth regulators has been a significant decline in the total number of organic acids (up to 2.35% at the option of Melaphen and to 2.50% at Obstaktin, LSD (p ≤0.05) = 0.06). By reducing the content in the fruits of organic acids to all variants increased the sugar-acid index. After each spraying tangerine on the treatment options plant growth regulators has been a significant increase the dry matter. Thus, the positive effect of plant growth regulators on all the quality characteristics of tangerine was shown. In the summer period, the treatment by regulators may have a protective effect, increases the content in plants the content of Indole-acetic acid. The plant growth regulators of new generation have a positive effect on quality of dwarf tangerine. Given that the plants of tangerine in the subtropical zone of Russia each summer have to drought and are losing not only in yield, fruit quality too, new regulators may exert a protective effect, because increases the content in plants is Indole-acetic acid, which activates gene expression of drought resistance.
De materia medica: where art and scientific principles pome together
Authors: OZDOGAN Elif
Published: May 2019

This essay interprets and analyses the painting called “Dioscoridesdescribing the mandrake”, which is currently located in apermanent exhibition at Wellcome Collection in London, UK.The painting features Pedanius Dioscorides, a Greek botanistand pharmacologist who practiced in the Roman Empire duringthe rule of Nero. Dioscorides is known for his influential DeMateria Medica, a five-volume book on medicinal uses of variousplants and herbs. What makes this script special and influentialis that it included a vast amount of herbs, detailed descriptions,scientific observations, as well as a scientific classification andorder. Upon reflection on this piece of art, I am reminded of themedical realm that we are gradually becoming a part of as medicalstudents. There is immense passion, knowledge and intelligencein how medicine became modern medicine today. For me, thepainting on Dioscorides’ De Materia Medica is a compelling visualrepresentation of centuries – long endeavor.
