Abstract. Models severely overestimate surface ozone in the Southeast US during summertime and this overestimation has implications for the design of air quality regulations. We use the GEOS-Chem model to interpret ozone observations from aircraft (SEAC4RS), ozonesondes (SEACIONS), and surface sites (CASTNET) in August–September 2013. After correcting for a 30–50 % NOx emission overestimate in the US EPA National Emission Inventory, we find that the model is unbiased relative to aircraft observations below 1 km. However, surface observations of maximum daily 8-h average (MDA8) ozone are still biased high in the model (averaging 48 ± 9 ppb) compared to observations (40 ± 9 ppb). The low tail in the observations (MDA8 ozone

Abstract. The Bering Strait connects the Arctic and Pacific oceans and separates the North American and Asian landmasses. The presently shallow ( ∼  53 m) strait was exposed during the sea level lowstand of the last glacial period, which permitted human migration across a land bridge today referred to as the Bering Land Bridge. Proxy studies (stable isotope composition of foraminifera, whale migration into the Arctic Ocean, mollusc and insect fossils and paleobotanical data) have suggested a range of ages for the Bering Strait reopening, mainly falling within the Younger Dryas stadial (12.9–11.7 cal ka BP). Here we provide new information on the deglacial and post-glacial evolution of the Arctic–Pacific connection through the Bering Strait based on analyses of geological and geophysical data from Herald Canyon, located north of the Bering Strait on the Chukchi Sea shelf region in the western Arctic Ocean. Our results suggest an initial opening at about 11 cal ka BP in the earliest Holocene, which is later than in several previous studies. Our key evidence is based on a well-dated core from Herald Canyon, in which a shift from a near-shore environment to a Pacific-influenced open marine setting at around 11 cal ka BP is observed. The shift corresponds to meltwater pulse 1b (MWP1b) and is interpreted to signify relatively rapid breaching of the Bering Strait and the submergence of the large Bering Land Bridge. Although the precise rates of sea level rise cannot be quantified, our new results suggest that the late deglacial sea level rise was rapid and occurred after the end of the Younger Dryas stadial.
Terrestrial laser scanning for quantifying small-scale vertical
movements of the ground surface in Artic permafrost regions

Published: August 2017

Abstract. Three-dimensional data acquired by terrestrial laser scanning (TLS) provides an accurate representation of Earth's surface, which is commonly used to detect and quantify topographic changes on a small scale. However, in Arctic permafrost regions the tundra vegetation and the micro-topography have significant effects on the surface representation in the captured dataset. The resulting spatial sampling of the ground is never identical between two TLS surveys. Thus, monitoring of heave and subsidence in the context of permafrost processes are challenging. This study evaluates TLS for quantifying small-scale vertical movements in an area located within the continuous permafrost zone, 50 km north-east of Inuvik, Northwest Territories, Canada. We propose a novel filter strategy, which accounts for spatial sampling effects and identifies TLS points suitable for multi-temporal deformation analyses. Further important prerequisites must be met, such as accurate co-registration of the TLS datasets. We found that if the ground surface is captured by more than one TLS scan position, plausible subsidence rates (up to mm-scale) can be derived; compared to e.g. standard raster-based DEM difference maps which contain change rates strongly affected by sampling effects.
REDCAPP (v1.0): parameterizing valley inversions in air temperature data downscaled from reanalyses
Authors: Cao Bin , Gruber Stephan , Zhang Tingjun
Published: August 2017

Abstract. In mountain areas, the use of coarse-grid reanalysis data for driving fine-scale models requires downscaling of near-surface (e.g., 2 m high) air temperature. Existing approaches describe lapse rates well but differ in how they include surface effects, i.e., the difference between the simulated 2 m and upper-air temperatures. We show that different treatment of surface effects result in some methods making better predictions in valleys while others are better in summit areas. We propose the downscaling method REDCAPP (REanalysis Downscaling Cold Air Pooling Parameterization) with a spatially variable magnitude of surface effects. Results are evaluated with observations (395 stations) from two mountain regions and compared with three reference methods. Our findings suggest that the difference between near-surface air temperature and pressure-level temperature (ΔT) is a good proxy of surface effects. It can be used with a spatially variable land-surface correction factor (LSCF) for improving downscaling results, especially in valleys with strong surface effects and cold air pooling during winter. While LSCF can be parameterized from a fine-scale digital elevation model (DEM), the transfer of model parameters between mountain ranges needs further investigation.
THE DEVELOPMENT OF 3D SUB-SURFACE MAPPING SCHEME AND ITS
APPLICATION TO MARTIAN LOBATE DEBRIS APRONS
Authors: Baik H. , Kim J.
Published: August 2017

Abstract. The Shallow Subsurface Radar (SHARAD), a sounding radar equipped on the Mars Reconnaissance Orbiter (MRO), has produced highly valuable information about the Martian subsurface. In particular, the complicated substructures of Mars such as polar deposit, pedestal crater and the other geomorphic features involving possible subsurface ice body has been successfully investigated by SHARAD. In this study, we established a 3D subsurface mapping strategy employing the multiple SHARAD profiles. A number of interpretation components of SHARAD signals were integrated into a subsurface mapping scheme using radargram information and topographic data, then applied over a few mid latitude Lobate Debris Aprons (LDAs). From the identified subsurface layers of LDA, and the GIS data base incorporating the other interpretation outcomes, we are expecting to trace the origin of LDAs. Also, the subsurface mapping scheme developed in this study will be further applied to other interesting Martian geological features such as inter crater structures, aeolian deposits and fluvial sediments. To achieve higher precision sub-surface mapping, the clutter simulation employing the high resolution topographic data and the upgraded clustering algorithms assuming multiple sub-surface layers will be also developed.
A PHOTOGRAMMETRIC PIPELINE FOR THE 3D RECONSTRUCTION OF CASSIS IMAGES ON BOARD EXOMARS TGO
Authors: Simioni E. , Re C. , Mudric T. , Pommerol A. , Thomas N. , Cremonese G.
Published: August 2017

Abstract. CaSSIS (Colour and Stereo Surface Imaging System) is the stereo imaging system onboard the European Space Agency and ROSCOSMOS ExoMars Trace Gas Orbiter (TGO) that has been launched on 14 March 2016 and entered a Mars elliptical orbit on 19 October 2016. During the first bounded orbits, CaSSIS returned its first multiband images taken on 22 and 26 November 2016. The telescope acquired 11 images, each composed by 30 framelets, of the Martian surface near Hebes Chasma and Noctis Labyrithus regions reaching at closest approach at a distance of 250 km from the surface. Despite of the eccentricity of this first orbit, CaSSIS has provided one stereo pair with a mean ground resolution of 6 m from a mean distance of 520 km. The team at the Astronomical Observatory of Padova (OAPD-INAF) is involved into different stereo oriented missions and it is realizing a software for the generation of Digital Terrain Models from the CaSSIS images. The SW will be then adapted also for other projects involving stereo camera systems. To compute accurate 3D models, several sequential methods and tools have been developed. The preliminary pipeline provides: the generation of rectified images from the CaSSIS framelets, a matching core and post-processing methods. The software includes in particular: an automatic tie points detection by the Speeded Up Robust Features (SURF) operator, an initial search for the correspondences through Normalize Cross Correlation (NCC) algorithm and the Adaptive Least Square Matching (LSM) algorithm in a hierarchical approach. This work will show a preliminary DTM generated by the first CaSSIS stereo images.
IMPROVED LARGE-SCALE SLOPE ANALYSIS ON MARS BASED ON CORRELATION OF SLOPES DERIVED WITH DIFFERENT BASELINES
Authors: Wang Y. , Wu B.
Published: August 2017

Abstract. The surface slopes of planetary bodies are important factors for exploration missions, such as landing site selection and rover manoeuvre. Generally, high-resolution digital elevation models (DEMs) such as those generated from the HiRISE images on Mars are preferred to generate detailed slopes with a better fidelity of terrain features. Unfortunately, high-resolution datasets normally only cover small area and are not always available. While lower resolution datasets, such as MOLA, provide global coverage of the Martian surface. Slopes generated from the low-resolution DEM will be based on a large baseline and be smoothed from the real situation. In order to carry out slope analysis at large scale on Martian surface based low-resolution data such as MOLA data, while alleviating the smoothness problem of slopes due to its low resolution, this paper presents an amplifying function of slopes derived from low-resolution DEMs based on the relationships between DEM resolutions and slopes. First, slope maps are derived from the HiRISE DEM (meter-level resolution DEM generated from HiRISE images) and a series of down-sampled HiRISE DEMs. The latter are used to simulate low-resolution DEMs. Then the high-resolution slope map is down- sampled to the same resolution with the slope map from the lower-resolution DEMs. Thus, a comparison can be conducted pixel-wise. For each pixel on the slope map derived from the lower-resolution DEM, it can reach the same value with the down-sampled HiRISE slope by multiplying an amplifying factor. Seven sets of HiRISE images with representative terrain types are used for correlation analysis. It shows that the relationship between the amplifying factors and the original MOLA slopes can be described by the exponential function. Verifications using other datasets show that after applying the proposed amplifying function, the updated slope maps give better representations of slopes on Martian surface compared with the original slopes.
CORRECTION OF OVERLAPPING MULTISPECTRAL LIDAR INTENSITY DATA:
POLYNOMIAL APPROXIMATION OF RANGE AND ANGLE EFFECTS
Authors: Yan W. Y. , Shaker A.
Published: August 2017

Abstract. Recent development of radiometric calibration, correction and normalization approaches have facilitated the use of monochromatic LiDAR intensity and waveform data for land surface analysis and classification. Despite the recent successful attempts, the majority of existing approaches are mainly tailor made for monochromatic LiDAR toward specific land surface scenario. In view of the latest development of multispectral LiDAR sensor, such as the Optech Titan manufactured by Teledyne Optech, a more generic approach should be developed so that the radiometric correction model is able to handle and compensate the laser energy loss with respect to different wavelengths. In this study, we propose a semi-physical approach that aims to utilize high order polynomial functions to model the distortion effects due to the range and the angle. To estimate the parameters of the respect polynomial functions for the range and angle, our approach first locates a pair of closest points within the overlapping LiDAR data strips and subsequently uses a non-linear least squares adjustment to retrieve the polynomial parameters based on the Levenberg-Marquardt algorithm. The approach was tested on a multispectral airborne LiDAR dataset collected by the Optech Titan for the Petawawa Research Forest located in Ontario, Canada. The experimental results demonstrated that the coefficient of variation of the intensity of channel 1 (1550 nm), channel 2 (1064 nm) and channel 3 (532 nm) were reduced by 0.1 % to 39 %, 10 % to 45 % and 12 % to 54 %, respectively. The striping noises, no matter found within single strip and overlapping strips, were significantly reduced after implementing the proposed radiometric correction.
PRECISION 3D SURFACE RECONSTRUCTION FROM LRO NAC IMAGES USING SEMI-GLOBAL MATCHING WITH COUPLED EPIPOLAR RECTIFICATION
Authors: Hu H. , Wu B.
Published: August 2017

Abstract. The Narrow-Angle Camera (NAC) on board the Lunar Reconnaissance Orbiter (LRO) comprises of a pair of closely attached high-resolution push-broom sensors, in order to improve the swath coverage. However, the two image sensors do not share the same lenses and cannot be modelled geometrically using a single physical model. Thus, previous works on dense matching of stereo pairs of NAC images would generally create two to four stereo models, each with an irregular and overlapping region of varying size. Semi-Global Matching (SGM) is a well-known dense matching method and has been widely used for image-based 3D surface reconstruction. SGM is a global matching algorithm relying on global inference in a larger context rather than individual pixels to establish stable correspondences. The stereo configuration of LRO NAC images causes severe problem for image matching methods such as SGM, which emphasizes global matching strategy. Aiming at using SGM for image matching of LRO NAC stereo pairs for precision 3D surface reconstruction, this paper presents a coupled epipolar rectification methods for LRO NAC stereo images, which merges the image pair in the disparity space and in this way, only one stereo model will be estimated. For a stereo pair (four) of NAC images, the method starts with the boresight calibration by finding correspondence in the small overlapping stripe between each pair of NAC images and bundle adjustment of the stereo pair, in order to clean the vertical disparities. Then, the dominate direction of the images are estimated by project the center of the coverage area to the reference image and back-projected to the bounding box plane determined by the image orientation parameters iteratively. The dominate direction will determine an affine model, by which the pair of NAC images are warped onto the object space with a given ground resolution and in the meantime, a mask is produced indicating the owner of each pixel. SGM is then used to generate a disparity map for the stereo pair and each correspondence is transformed back to the owner and 3D points are derived through photogrammetric space intersection. Experimental results reveal that the proposed method is able to reduce gaps and inconsistencies caused by the inaccurate boresight offsets between the two NAC cameras and the irregular overlapping regions, and finally generate precise and consistent 3D surface models from the NAC stereo images automatically.
PHOTOMETRIC STEREO SHAPE-AND-ALBEDO-FROM-SHADING FOR PIXEL-LEVEL RESOLUTION LUNAR SURFACE RECONSTRUCTION
Authors: Liu W. C. , Wu B.
Published: August 2017

Abstract. Shape and Albedo from Shading (SAfS) techniques recover pixel-wise surface details based on the relationship between terrain slopes, illumination and imaging geometry, and the energy response (i.e., image intensity) captured by the sensing system. Multiple images with different illumination geometries (i.e., photometric stereo) can provide better SAfS surface reconstruction due to the increase in observations. Photometric stereo SAfS is suitable for detailed surface reconstruction of the Moon and other extra-terrestrial bodies due to the availability of photometric stereo and the less complex surface reflecting properties (i.e., albedo) of the target bodies as compared to the Earth. Considering only one photometric stereo pair (i.e., two images), pixel-variant albedo is still a major obstacle to satisfactory reconstruction and it needs to be regulated by the SAfS algorithm. The illumination directional difference between the two images also becomes an important factor affecting the reconstruction quality. This paper presents a photometric stereo SAfS algorithm for pixel-level resolution lunar surface reconstruction. The algorithm includes a hierarchical optimization architecture for handling pixel-variant albedo and improving performance. With the use of Lunar Reconnaissance Orbiter Camera - Narrow Angle Camera (LROC NAC) photometric stereo images, the reconstructed topography (i.e., the DEM) is compared with the DEM produced independently by photogrammetric methods. This paper also addresses the effect of illumination directional difference in between one photometric stereo pair on the reconstruction quality of the proposed algorithm by both mathematical and experimental analysis. In this case, LROC NAC images under multiple illumination directions are utilized by the proposed algorithm for experimental comparison. The mathematical derivation suggests an illumination azimuthal difference of 90 degrees between two images is recommended to achieve minimal error in SAfS reconstruction while results using real data presents similar pattern. Although the algorithm is designed for lunar surface reconstruction, it is likely to be applicable on other extra-terrestrial bodies such as Mars. The results and findings from this research is of significance for the practical use of photometric stereo and SAfS in the domain of planetary remote sensing and mapping.
Definitive evidence of the Mediterranean Outflow
heterogeneity. Part 1: at the Strait of Gibraltar entrance
Authors: Millot Claude
Published: August 2017

Abstract. All most recent papers about the Mediterranean Outflow (MO) assume that it is homogeneous at least in the western side of the Strait of Gibraltar and that its splitting into veins in the Atlantic Ocean is due to bathymetric effects at the Strait exit while we demonstrate that proofs about the MO heterogeneity within the whole Strait have been available since the mid 1980's at least. We focus herein on data collected at the Strait entrance in 1985 (Part 1), before analyzing 1985–1986 data within the Strait (Part 2) and data collected during the MO-2009 experiment at the Strait exit (Part 3). Having demonstrated that the MO is markedly heterogeneous from the Strait entrance to the Strait exit, our three papers demonstrate that the splitting into veins is essentially a direct consequence of the sea functioning. Indeed, veins have hydrological characteristics mainly dependent on those of the intermediate and deep Mediterranean Waters (MWs) formed in both the eastern and the western basins of the Sea, as well as on those of the Atlantic Waters (AWs) that mixed in the Strait with these MWs, the bathymetry at and downstream from the Strait exit playing a negligible role. Herein, we demonstrate that four-five MWs can be clearly identified at the Strait entrance, as we previously hypothesized, moreover forming relatively thick and homogeneous superimposed layers that are much more individualized than anywhere else in the Sea. For the first time ever, we provide numerous examples of density instabilities in all these layers that clearly illustrate the processes leading to such an increased stratification at the Strait entrance. So as to motivate theoretical analyses and numerical simulations that appear to be of dramatic interest, we hypothesize that the isopycnals slope (of a few %) across the Strait within the MO itself, that is a direct consequence of both the Coriolis effect and the different outflowing or overflowing velocities of the MWs, could be the main mechanism responsible for such a layering of the MO.
Definitive evidence of the Mediterranean Outflow
heterogeneity. Part 2: all along the Strait of Gibraltar
Authors: Millot Claude
Published: August 2017

Abstract. We have demonstrated in Part 1, with only a CTD transect across the Strait at 6°05' W, that the Mediterranean Outflow (MO) was definitely heterogeneous there. A yo-yo CTD time series has also provided astounding examples of both the marked layering that the Mediterranean Waters (MWs) display on the vertical at the Strait entrance (5°43' W), i.e. just upstream from the Camarinal sills (5°45' W), as well as the tremendous instability processes occurring in all layers. We focus herein on similar data collected within the Strait at both 5°50' W and 6°05' W (downstream from the Camarinal and Espartel sills, resp.) during five campaigns of the 1985–1986 GIBEX. We first show additional transects supporting the demonstration we made at 6°05' W, and we demonstrate that the marked heterogeneity of the MO within the Strait is clearly on the horizontal; as we expected, densest (resp. lightest) MWs flow on the bottom on its left-hand (resp. right-hand) side and all MWs are juxtaposed side by side. We also demonstrate that the density range within the MO in the western side of the Strait (6°05' W) is at least 0.5 kg m−3, which is the density range, in the vicinity of the Cape St Vincent (8°30' W), of the four veins formed by the MO splitting. We show that the lightest component of the MO has started to be split as soon as Camarinal sills and sink all along the Strait. The splitting of the MO into veins is thus mainly due to its intrinsic heterogeneity, which is a direct consequence of the Sea functioning and of the mixing, within the Strait itself, of the MO with this or that type of Atlantic Waters (AWs). Therefore, the bathymetry in the Strait, and even in the Strait exit surroundings (near 6°20' W), has no major effect on the MO characteristics in the whole Ocean. We also focus on a yo-yo CTD time series collected during ~24 h at 6°05' W which shows that markedly different MWs have been passing by, clearly demonstrating that the horizontally heterogeneous MO is significantly meandering within the Strait. Finally, we confirm one of our previous results that, provided the temporal variabilities of both the MWs and the AWs are not too large, significant relationships can possibly be established between the characteristics of the MWs at the Strait extremities, or at least that the slope of the mixing lines on a q-S diagram provides significant information. Parts 1 and 2 of our trilogy must be assimilated before reading Part 3.
What Is the Cause of Graduates’ Unemployment? Focus on Individual Concerns and Perspectives
Authors: Hwang Youngsik
Published: August 2017

The graduate unemployment rate is one of the current issues being discussed by higher education scholars. College students spend their time and money in order to receive educational advantages unavailable to high school graduates. So if they face unemployment, they are more vulnerable to unfavorable economic conditions because they have already spent their resources pursuing higher education. This paper examines the reasons why college graduates are facing unemployment in the competitive market. There are several factors that explain their unemployment status, and this paper identifies each component at an individual level. With specific analysis of the unemployment phenomena, this paper provides direction for further research.
Radiation-induced Neurocognitive Dysfunction in Head and Neck Cancer Patients
Authors: De Felice Francesca , Blanchard Pierre
Published: August 2017

It might seem odd that a special issue about Gianni Bonadonna would publish a review on radiation-induced neurocognitive dysfunction. Dr. Gianni Bonadonna is considered a pioneer in medical oncology history, mainly due to new and revolutionary treatment approaches proposed in breast cancer and Hodgkin lymphoma. He had an active role in the field of medical oncology, especially through lectures and textbooks. He shared his considerable insight of understanding cancer behavior and evaluating research advances over the years to prevent tumor recurrence and preserve patients from unnecessary toxicity. From a theoretical point of view, this complex vision is valid for all malignancies and can be indirectly shifted to every primary cancer, including head and neck cancer (HNC). During the last decades, multidisciplinary treatment for HNC has improved clinical outcomes but makes acute and late toxicity challenging. This article highlights the main central nervous structures that have a major impact on the development of neurocognitive dysfunction after radiotherapy for HNC. We briefly summarize the specific structure contouring instructions and the dose-volume histogram parameters. The aim is to raise awareness in clinicians in defining normal tissues to optimize radiotherapy regimens.

In the U.S., sustainability accounting reporting is developing and becoming more prevalent in public companies. This paper reviews accounting literature and Dow 30 companies’ websites, presents a comprehensive view of the landscape of sustainability accounting reporting, and identifies seven issues of the reporting frameworks of sustainability accounting, i.e., (1) definitions, (2) measurements and disclosures, (3) motivations, (4) compliance, (5) enforcement, (6) standardization, and (7) the ultimate effect on reliability and comparability.An archival analysis approach is used to summarize and compare Dow 30 sustainability accounting reporting frameworks and information disclosed in 2015 annual reports and websites. The most popular framework is the Global Reporting Initiative (GRI) G4 Sustainability Reporting Guidelines. Some companies developed sustainability accounting reporting frameworks and others did not disclose any information regarding sustainability accounting reporting. Although the GRI framework is the most used, external assurance is present in only a few companies.
Contributing Factors to Older Teen Mothers’ Academic Success as Very Young Mothers
Authors: Hernandez Jennifer , Abu Rabia Hazza M.
Published: August 2017

This qualitative study explores the factors contributed to 13 older teen mothers’ academic success as very young mothers. The participants were older teen mothers who were pregnant and gave birth at the age of 16 years old or younger, and who have achieved a college degree from an accredited college or university while they raised their child(ren). In depth interviews were employed to document and analyze older teen mother experiences. One-on-one interviews with the participants revealed multiple factors assisted older teen mothers’ academic success, including family and other individuals support, teachers, early school attendance, personal drive, and responsibilities. While further research is needed, these findings suggest that developing holistic services for teen mothers is needed to assist in developing future academic success. A holistic approach includes mind, body and spirit (Arsenian, n.d.). These recommended services could be developed within existing programs and should include activities to promote self-awareness, health and some form of exploration of values, faith and family.

What Explains German Export Performances? Spatial Econometric Evidences: 1995 to 2014
Authors: Yang Wen , Liu Yi-Cheng , Mai Chao-Cheng
Published: August 2017

German exports achieved outstanding performances, yet there is lack of research utilizing spatial econometric evidences. This paper explores four explanations and evaluates their empirical contributions: (i) German exports were highly correlated to its imports. Thus, its exports built upon bilateral trade flows. (ii) German exported to countries with high GDP per capita with the capability and the demand of high-quality and less price-elastic goods. (iii) It exported to countries with economic integration with other countries such as free trade agreements. (iv) Its exports broadened from Europe to other countries in America and the Asia Pacific region with increasing total export-volume growth. Thus, German exports benefited from the free trade flow to a few EU member countries, those are close geographically and culturally to Germany. The empirical evidence also points out that the changing geospatial distribution of German exports is another key factors to its export success. The spatial Durbin model was identified to be the best fit model of all after a series of tests. Decisive determinants of its exports performance were found through the estimation besides geospatial analyses of its exports by employing Moran’s I.

Published: August 2017

In this paper, I conduct a review of the IFRS and U.S. GAAP convergence history and the related studies. I first review the history of the early accounting standards harmonization efforts in the Europe Union in the 1970s and 1980s. Next, I discuss the modern convergence efforts as well as the voluntary adoption of the International Accounting Standards (IAS) in the 1990s and early 2000s. I then discuss the concurrent global accounting standards convergence efforts from 2002 to present, including the mandatory IFRS adoption in the EU in 2005 and the convergence between the IFRS and U.S. GAAP. As I review the harmonization and convergence efforts over time, I discuss studies related to each stage of the history. I contribute to the accounting literature by providing a historical review of the IFRS-U.S. GAAP convergence process and relevant studies that can be useful for accounting educators and students, researchers, practitioners, and standards setters.

анализе использовано модели эконометрического моделирования методом бинарной
логистической регрессии. Было показано,что молодые женщины, которые встают
на учёт в районных бюро по трудоустройству подвергаются длительному процессу
безработицы, чем мужчины. Отсутстствие профессионального стажа, уровень
образования, небольшое количество выученных профессий, а также имение детей
ограничивают трудоустройство молодых безработных. Кроме того, на перспективы
трудоустройства исследуемой группы важное влияние имеет уровень развития
экономики в данном регионе.

Innovation – Populist Slogan, Why?
Authors: Ponický Peter , Zamarský Vítězslav
Published: August 2017

Nowadays, innovation is perhaps the most widely spoken global keyword in the field of
economy. Everyone talks about innovation and the European Union already for more than
a decade, has wanted through innovation to catch up with and take the leading position in
the world. However, what is the reality? Europe still has difficulties with the pace of economic
growth, which according to many is joined combined with innovation and knowledge.
Asian countries often set a price of an innovated product of poor quality and with
no added value that includes huge cost of efficient marketing and aggressive advertising.
Therefore, is innovation everything what is called this way? Though the world controls the
speed and acceleration of changes, it does not mean necessarily an advantage or positive
effects. And evolution of a star in a supernova and then a black hole is in the final stages
accelerated in an unusual way.
The inspiration for our article was slanted to cheap using the word “innovation”, just
because it is a European priority. We just drew from his knowledge and life experiences.

Rifaximin Stability: A Look at UV, IR, HPLC, and Turbidimetry Methods
Authors: Kogawa Ana Carolina , Salgado Hérida Regina Nunes
Published: August 2017

The study of the stability of medicines is mandated by the International Conference on Harmonization and the World Health Organization. Rifaximin, an antimicrobial marketed in the form of tablets, has no record of stability studies. Thus, the objective of the present work was to investigate the behavior and stability of rifaximin tablets for 6 months under simultaneous conditions of temperature and humidity by UV, IR, HPLC, and turbidimetry techniques. After 6 months of stability study, rifaximin tablets were shown to obey zero-order kinetics when analyzed by physicochemical methods and second-order kinetics when analyzed by a microbiological method. However, the UV method was not suitable for the evaluation of rifaximin. IR, HPLC, and turbidimetry methods can already be used to evaluate the stability of rifaximin tablets. It is important to analyze products with more than one type of method before releasing results mainly in the case of antimicrobial products in which the association of physicochemical and microbiological techniques must be a rule. Rifaximin tablets can be considered stable after 6 months under conditions of 40 ± 2°C and 75 ± 5% relative humidity.
Rapid Determination of Amino Acids in Beer, Red Wine, and Donkey-Hide Gelatin by Gradient Elution of HPLC: From Micellar Liquid Chromatography to High Submicellar Liquid Chromatography
Authors: Xie Yunfei , Luo Tian , Yang Jing , Dong Yuming
Published: August 2017

Amino acids (AAs) in beer, red wine, and donkey-hide gelatin were rapidly determined by gradient LC elution from micellar LC to high submicellar LC. Mobile phase A was a 0.075 M sodium dodecyl sulfate solution containing 20 mM ammonium acetate with a pH value adjusted to 3.5 with acetic acid solution, and mobile phase B was acetonitrile. Optimized chromatographic conditions were as follows: mobile phase B increased from 25 to 60% (v/v) in 30 min and the use of a Venusil XBP C18 column (5 µm, 250 × 4.6 mm) as the stationary phase, with a column temperature of 35°C, flow rate of 1.2 mL/min, and detection wavelength of 266 nm. The results indicated good linearity (r2 ≥ 0.9924). The intraday precision of the retention time was RSD ≤ 1.1%, whereas interday was RSD ≤ 3.2%; intraday precision of the peak area was RSD ≤ 3.3%, whereas interday was RSD ≤ 4.9%. The range of recovery was 94.6–102.4%. The RSDs of the retention time for the AAs for the different samples were 0.04–0.31%.

A consortium of European enterprises and research institutions has been engaged in the Feed-Code Project with the aim of addressing the requirements stated in European Union Regulation No. 767/2009, concerning market placement and use of feed of known and ascertained botanical composition. Accordingly, an interlaboratory trial was set up to compare the performance of different assays based either on optical microscope or DNA analysis for the qualitative and quantitative identification of the composition of compound animal feeds. A tubulin-based polymorphism method, on which the Feed-Code platform was developed, provided the most accurate results. The present study highlights the need for the performance of ring trials for the determination of the botanical composition of animal feeds and raises an alarm on the actual status of analytical inaccuracy.
ANÁLISE DA EXISTÊNCIA DE DISCRIMINAÇÃO SALARIAL ENTRE HOMENS E MULHERES NA INDÚSTRIA DE TRANSFORMAÇÃO DO ESTADO DE SANTA CATARINA
Authors: Mattei Taíse Fatima , Baço Fernanda Mendes Bezerra
Published: August 2017

Nas últimas décadas, o Brasil vem passando por transformações em seu mercado de trabalho que culminaram com a maior participação feminina em todos os setores produtivos. No entanto, ainda é observada uma diferença salarial entre homens e mulheres, que pode ser fruto de diferenças nos atributos produtivos entre os gêneros ou pode indicar um favorecimento salarial ao gênero masculino. Por isso, este trabalho tem por objetivo verificar se a existência de diferença salarial entre homens e mulheres na indústria de transformação do estado de Santa Catarina pode ser atribuída à discriminação. Para esta finalidade utilizou-se o método de decomposição de rendimentos de Oaxaca-Blinder.  Este tema se torna relevante na medida em que busca conhecer as características do mercado de trabalho catarinense, uma vez que existem poucos estudos sobre este assunto no Estado. Os dados usados no trabalho são provenientes da RAIS – Relação Anual de Informações Sociais, o que torna a pesquisa diferenciada, uma vez que os trabalhos sobre discriminação utilizam, na maioria das vezes, dados da PNAD. Os resultados obtidos sugerem que existe diferença salarial a favor dos homens e a maior parte desta diferença é atribuída a fatores não explicados pelos atributos dos trabalhadores que pode indicar a existência de discriminação nesses setores.
“O DEPARTAMENTO MÉDICO-LEGAL DEVERIA SER BEM TRATADO”: O (NÃO) RECONHECIMENTO NA ATIVIDADE DOS SERVIDORES DO DEPARTAMENTO MÉDICO-LEGAL
Authors: Cavedon Neusa Rolita
Published: August 2017

O artigo tem por objetivo identificar se existe reconhecimento no universo de trabalho daqueles que atuam no Departamento Médico-Legal (DML) do Instituto-Geral de Perícias (IGP) do Rio Grande do Sul. O trabalho não é uma atividade de cunho individual, ele configura-se a partir de uma relação social, portanto, há um saber que se dá no âmbito do coletivo. Para Gernet e Dejours (2011), a dimensão coletiva ganha espaço na medida em que o reconhecimento passa a ser experimentado pelos integrantes da organização. A pesquisa de cunho qualitativo incluiu idas a campo de agosto até dezembro de 2013. Foram realizadas sete entrevistas semiestruturadas com os profissionais da equipe de plantão que atuam em um determinado dia da semana. Os achados revelaram que o reconhecimento pelos superiores hierárquicos, pelos colegas de outro departamento da instituição e pela sociedade, inexistem; por parte da polícia, o reconhecimento é parcial. O reconhecimento simbolicamente significativo se dá pelos pares da equipe de plantão, mas acaba não sendo suficiente para evitar o sofrimento.
O PÓS-MODERNISMO NA LITERATURA E NOS ESTUDOS ORGANIZACIONAIS: MANIFESTAÇÕES E CARACTERÍSTICAS
Authors: Mastella Adriano Silveira , Godoi Christiane Kleinubing
Published: August 2017

Este ensaio tem a intenção de analisar as características do paradigma pós-moderno presentes simultaneamente nos estudos organizacionais e no campo da literatura. As características analisadas são: a) a paródia, o pastiche e a ironia; b) as identidades fragmentadas; c) a hiper-realidade - substituição do mundo real em que as simulações têm precedência sobre a ordem social contemporânea e; d) a queda das grandes narrativas. Para tanto, são tomados como exemplo a serem analisados textos produzidos no campo dos estudos organizacionais e outros do campo literário. Após a análise da manifestação de cada característica definida, desenvolve-se um painel demonstrativo das reflexões. A finalidade última deste ensaio reside em, ao analisar os antecedentes literários do pós-modernismo nos estudos organizacionais, constituir-se como um exercício de prática de ensino da epistemologia nas organizações.
