Examining the Moderating Effects of Time-Since-Adoption on the Nexus Between Business Intelligence Systems and Organisational Performance
Authors: Owusu Acheampong
Published: May 2019

This article investigates the post-adoption impacts of business intelligence (BI) systems on organisational performance of Ghanaian banks through the lens of the balanced scorecard. It also examines if time-since-adoption moderates the hypothesized relationship between BI systems adoption and the banks' organizational performance. A survey data of 130 Ghanaian bank officials was analysed through a partial least square structural equation modelling (PLS-SEM) approach to examine the relationship among the study constructs. The results indicated that BI Systems indeed impacted significantly on Ghanaian banks' organisational performance by improving employee learning and growth, enhancing their internal business processes and improving their customer management performances. Nonetheless, BI Systems did not have a direct significant effect on the banks financial performance. Moreover, the findings show that there is no significant difference between early-adopters and late-adopters in terms of BI Systems impacts on the banks' organisational performance. Other implications are also discussed.

Authors: Verma Surabhi , Chaurasia Sushil
Published: May 2019

This article aims to empirically investigate the factors that affects the adoption of big data analytics by firms (adopters and non-adopters). The current study is based on three feature that influence BDA adoption: technological context (relative advantage, complexity, compatibility), organizational context (top management support, technology readiness, organizational data environment), and environmental context (competitive pressure, and trading partner pressure). A structured questionnaire-based survey method was used to collect data from 231 firm managers. Relevant hypotheses were derived and tested by partial least squares. The results indicated that technology, organization and environment contexts impact firms' adoption of big data analytics. The findings also revealed that relative advantage, complexity, compatibility, top management support, technology readiness, organizational data environment and competitive pressure have a significant influence on the adopters of big data analytics, whereas relative advantage, complexity and competitive pressure have a significant influence on the non-adopters of big data analytics.

Published: May 2019

In recent years, graph database systems have become very popular and been deployed mainly in situations where the relationship between data is significant, such as in social networks. Although they do not require a particular schema design, a data model contributes to their consistency. Designing diagrams is an approach to satisfying this demand for a conceptual data model. While researchers and companies have been developing concepts and notations for graph database modeling, their notations focus on their specific implementations. In this article, the authors propose a diagram to address this lack of a generic and comprehensive notation for graph databases modeling, named GRAPHED (Graph Description Diagram for Graph Databases). The authors verified the effectiveness and compatibility of GRAPHED in two case studies: fraud identification, and a biological network model.

С помощью нелинейной пары Лакса путем разделения временных и пространственных переменных эта иерархия сводится к семейству систем Неймана с обратным временем. Показано, что такие обратные системы Неймана интегрируемы по Лиувиллю, а их находящиеся в инволюции решения дают конечнопараметрические решения иерархии КдФ отрицательного порядка. Приведено уравнение Новикова отрицательного порядка, задающее конечномерное инвариантное подпространство потоков КдФ отрицательного порядка. Путем введения переменной Абеля-Якоби эти потоки интегрируются с решениями Абеля-Якоби на многообразии на римановой поверхности. Наконец, изучается обращение Римана-Якоби для решений Абеля-Якоби, из которого получаются некоторые квазипериодические решения иерархии КдФ отрицательного порядка.

Faced with the reemergence of yellow fever (YF) in the metropolitan region of São Paulo, Brazil, we developed a retrospective study to describe the cases of YF attended at the Institute of Infectology Emilio Ribas from January to March 2018 and analyze the factors associated with death, from the information obtained in the hospital epidemiological investigation. A total of 72 cases of sylvatic YF were confirmed, with 21 deaths (29.2% lethality rate). Cases were concentrated in males (80.6%) and in the age group of 30 to 59 years (56.9%). Two logistic regression models were performed, with continuous variables adjusted for the time between onset of symptoms and hospitalization. The first model indicated age (odds ratiosadjusted [ORadj]: 1.038; CI 95%: 1.008–1.212), aspartate aminotransferase (AST) (ORadj: 1.038; CI 95%: 1.005–1.072), and creatinine (ORadj: 2.343; CI 95%: 1.205–4.553) were independent factors associated with mortality. The second model indicated age (ORadj: 1.136; CI 95%: 1.013–1.275), alanine aminotransferase (ALT) (ORadj: 1.118; CI 95%: 1.018–1.228), and creatinine (ORadj: 2.835; CI 95%: 1.352–5,941). The risk of death in the model with continuous variables was calculated from the increase of 1 year (age), 1 mg/dL (creatinine), and 100 U/L for AST and ALT. Another logistic regression analysis with dichotomous variables indicated AST > 1,841 IU/L (ORadj: 12.92; CI 95%: 1.50–111.37) and creatinine > 1.2 mg/dL (ORadj: 81.47; CI 95%: 11.33–585.71) as independent factors associated with death. These results may contribute to the appropriate clinical management of patients with YF in health-care services and improve the response to outbreaks and public health emergencies.
Traduzindo verbos de movimento do inglês para o português: léxico e construções
Authors: Moura Heronides , Badaracco Lucas
Published: May 2019

Neste artigo, investigamos as implicações tradutórias do uso de verbos movimento no inglês e no português brasileiro (PB) à luz da Linguística Cognitiva a partir de narrações de partidas de basquetebol: um corpus que constitui um contexto natural de realização da língua falada. Analisamos duas partidas da National Basketball Association (NBA). Em total, foram compiladas 104 ocorrências de verbos de movimento, 51 em inglês e 53 em PB. Quanto aos tipos, foram constatados 46 diferentes em inglês e 26 em PB. Isso sugere que as narrações são mais ou menos equivalentes no que concerne ao estilo narrativo, pois ambas usam uma quantidade parecida de verbos. Entretanto, tem-se uma assimetria em relação à variedade de verbos de movimento empregados e à sua semântica. Enquanto no inglês há maior variedade de verbos de movimento, no PB ela é menor. Nesta língua, por sua vez, a preferência são verbos de movimento menos específicos, que indicam DIREÇÃO, sem muitas informações de MODO. Tais diferenças são a fonte das dificuldades da tradução de verbos de movimento, do inglês para o português. No que concerne aos estudos da tradução, esta pesquisa corrobora a Hipótese do Item Único, segundo a qual um item é único para uma dada língua, se os contextos gramaticais em que ele aparece são únicos daquela língua.
Uma abordagem reflexiva de ensino de prática de tradução (semi-)automatizada para formação de tradutores
Authors: Stupiello Érika Nogueira de Andrade
Published: May 2019

A adoção de sistemas de memória tem promovido transformações definitivas no desenvolvimento e nos critérios de contratação de traduções de textos em formato eletrônico. Com o objetivo de examinar a influência do uso dessas ferramentas na produção de tradutores em formação, este trabalho apresenta um estudo que propõe uma abordagem reflexiva de análise da produção tradutória de estudantes em treinamento acadêmico. Para tanto, oito participantes do terceiro ano de um curso de graduação em Tradução foram convidados a traduzirem três contratos do inglês para o português com e sem o uso do sistema Worfast Classic (versão 6.0). Os resultados da análise da produção dos estudantes indicam que aqueles que utilizaram a ferramenta produziram traduções mais uniformes, com alto índice de semelhança entre elas, o que pode ser indicativo da influência da memória no trabalho de tradução. Considerando a escassez de pesquisas voltadas à análise da maneira como tradutores se relacionam com as ferramentas que empregam em seu trabalho e o modo como são afetados por elas, espera-se contribuir para um melhor entendimento das possíveis implicações envolvidas na associação entre o tradutor e tecnologias como os sistemas de memória no trabalho de tradução.

A tradução criativa de Paulo Leminski do carpe diem horaciano
Authors: Pereira Lívia Mendes
Published: May 2019

O presente trabalho estuda e divulga o “projeto tradutório” do poeta e tradutor curitibano Paulo Leminski, com enfoque nas traduções que este realizou de textos da tradição greco-romana. Como pode ser constatado na leitura de sua biografia e como pode ser recorrentemente percebido nos temas que frequentam sua obra, o autor foi um conhecedor e divulgador da Língua e da Literatura Latina. Estudado inicialmente no mosteiro São Bento, na cidade de São Paulo, esse idioma antigo constituiu uma importante fonte criativa revisitada e repensada durante toda sua carreira literária. Além de traduções feitas diretamente do Latim como as da Ode I, 11, de Horácio (1984), e do Satyricon, de Petrônio (1985), o trabalho com textos literários latinos também pode ser encontrado em obras como Metaformose e Catatau. Neste estudo, daremos uma atenção especial à tradução realizada por Leminski da ode Horaciana em seu diálogo com a tradução do mesmo poema realizada por seu amigo e principal referencial teórico, o poeta Augusto de Campos. Destacaremos, portanto, as principais características de cada tradução e as coincidências e diferenças existentes entre elas, pautando-nos na teoria da tradução como recriação, advinda dos ideais poundianos do make it new.
Strategies of method selection for fine-scale PM2.5 mapping in an intra-urban area using crowdsourced monitoring
Authors: Xu Shan , Zou Bin , Lin Yan , Zhao Xiuge , Li Shenxin , Hu Chenxia
Published: May 2019

Abstract. Fine particulate matter (PM2.5) is of great concern to the
public due to its significant risk to human health. Numerous methods have
been developed to estimate spatial PM2.5 concentrations in unobserved
locations due to the sparse number of fixed monitoring stations. Due to an
increase in low-cost sensing for air pollution monitoring, crowdsourced
monitoring of exposure control has been gradually introduced into cities.
However, the optimal mapping method for conventional sparse fixed
measurements may not be suitable for this new high-density monitoring
approach. This study presents a crowdsourced sampling campaign and strategies
of method selection for 100 m scale PM2.5 mapping in an
intra-urban area of China. During this process, PM2.5 concentrations
were measured by laser air quality monitors through a group of volunteers
during two 5 h periods. Three extensively employed modelling methods
(ordinary kriging, OK; land use regression, LUR; and regression kriging,
RK) were adopted to evaluate the performance. An interesting finding is that
PM2.5 concentrations in micro-environments varied in the intra-urban
area. These local PM2.5 variations can be easily identified by
crowdsourced sampling rather than national air quality monitoring stations.
The selection of models for fine-scale PM2.5 concentration mapping
should be adjusted according to the changing sampling and pollution
circumstances. During this project, OK interpolation performs best in
conditions with non-peak traffic situations during a lightly polluted period
(holdout validation R2: 0.47–0.82), while the RK modelling can perform
better during the heavily polluted period (0.32–0.68) and in conditions with
peak traffic and relatively few sampling sites (fewer than ∼100) during the lightly polluted period (0.40–0.69). Additionally, the LUR
model demonstrates limited ability in estimating PM2.5 concentrations on
very fine spatial and temporal scales in this study (0.04–0.55), which
challenges the traditional point about the good performance of the LUR model
for air pollution mapping. This method selection strategy provides empirical
evidence for the best method selection for PM2.5 mapping using
crowdsourced monitoring, and this provides a promising way to reduce the
exposure risks for individuals in their daily life.

Abstract. NASA deployed an airborne UV/Visible spectrometer, GeoTASO, in May–June 2017 to produce high resolution (approximately 250 × 250 m), gapless NO2 datasets over the western shore of Lake Michigan and over the Los Angeles Basin. Results show that the airborne tropospheric vertical column retrievals compare well with ground-based Pandora spectrometer column NO2 observations (r2 = 0.91 and slope of 1.03). Apparent disagreements between the two measurements can be sensitive to the coincidence criteria and are often associated with large local variability, including rapid temporal changes and also spatial heterogeneity that may be observed differently by the sunward viewing Pandora observations. The gapless mapping strategy executed during the 2017 GeoTASO flights provides data suitable for averaging to coarser areal resolutions to simulate satellite retrievals. As simulated satellite pixel area increases to values typical of TEMPO, TROPOMI, and OMI, the agreement with Pandora measurements is degraded as localized polluted plumes observed by Pandora are spatially averaged over larger areas (aircraft-to-Pandora slope: TEMPO scale = 0.88; TROPOMI scale = 0.77; OMI scale = 0.57). This behavior suggests that satellite products are representative of individual Pandora observations up to a certain pollution scale that depends on satellite spatial resolution. In these two regions, Pandora and TEMPO or TROPOMI have the potential to compare well up to pollution scales of 30 x 1015 molecules cm−2. Two publicly available OMI tropospheric NO2 retrievals are both found to be biased low with respect to Pandora observations (NASA V3 Standard Product slope = 0.18 and Berkeley High Resolution Product slope = 0.30). However, the agreement improves when higher resolution a priori inputs are used for the tropospheric air mass factor calculation. Overall, this work explores best practices for satellite validation strategies by showing the sensitivity to product spatial resolution and demonstrates how the high spatial resolution NO2 data retrieved from airborne spectrometers, such as GeoTASO, can be used with high temporal resolution surface observations to evaluate the influence of spatial heterogeneity on validation results.
Methane (CH4) and nitrous oxide (N2O) from ground-based FTIR

satellite data

Abstract. A ground based high spectral resolution Fourier transform infrared (FTIR) spectrometer has been operational at Addis Ababa (9.0° N, 38.76° E, 2443 m a.s.l.) since May 2009 to obtain information on the total column abundances and vertical distribution of various constituents in the atmosphere. The retrieval strategy and the results on information content and corresponding full error budget evaluation for methane and nitrous oxide retrievals are presented. They reveal the high quality of FTIR measurements at Addis Ababa. The FTIR products of CH4 and N2O have been compared to coincident volume mixing ratio (VMR) measurements obtained from the reduced spectral resolution (Institute of Meteorology and Climate Research) IMK/IAA MIPAS satellite instrument (Version V5R_CH4_224 and V5R_N2O_224), the Microwave Limb Sounder on board of the Aura satellite (Aura/MLS) (MLS v3.3 of N2O and CH4 derived from MLS v3.3 products of CO, N2O and H2O) and the Atmospheric Infrared Sounder (AIRS). From comparison of FTIR CH4 and IMK/IAA MIPAS V5R_CH4_224, a statistically significant bias between −4.8 and +4.6 % in altitude ranges of the upper troposphere and lower stratosphere (15–27 km) are determined. The largest negative bias in FTIR CH4 is found in the altitude range of 11–19 km with a maximum difference of −0.08 ppmv (−4.8 %) at around 15 km, a positive bias of less than 0.14 ppmv (9 %) is found in the altitude range of 21 to 27 km with a maximum value at around 27 km with respect to AIRS. On the other hand, comparison of CH4 from ground based FTIR and MLS-derived CH4 (version 3.3) indicate existence of a signiﬁcant positive bias of 2.3 % to 11 % in the altitude range of 20 to 27 km and a negative bias −1.7 % at 17 km. In the case of N2O derived from FTIR and MIPAS V5R_N2O_224 comparison, a signiﬁcant positive bias of less than 15 % in the altitude range 22–27 km with a maximum value at around 25 km and a negative bias of −7 % have been found at 17 km. A positive bias of less than 18.6 % in FTIR N2O for the altitude below 27 km is noted when compared to MLS v3.3 N2O. Precision of ground based FTIR CH4 and N2O in the upper troposphere and lower stratosphere over Addis Ababa are better than 7.2 % and 9 %, respectively which are comparable to the bias obtained from the comparisons.

Abstract. Pollen records from Siberia are mostly absent in global or Northern Hemisphere synthesis works. Here we present a taxonomically harmonized and temporally standardized pollen dataset that was synthesized using 173 palynological records from Siberia and adjacent areas (northeast Asia, 50°–180° E and 42°–75° N). Pollen data were taxonomically harmonized, that is the original 437 taxa were transformed to 106 combined pollen taxa. Age-depth models for all records were revised by applying a constant Bayesian age-depth modelling routine. The pollen dataset is available as count data and percentage data in a table format (taxa vs. samples) with age information for each sample. The dataset has relatively few sites covering the last glacial period between 40 and 11.5 cal ka BP (calibrated thousand years before present 1950 CE) particularly from the central and western part of the study area. In the Holocene period, the dataset has many sites from most of the area except the central part of Siberia. Of the 173 pollen records, 81 % of pollen counts were downloaded from open databases (GPD, EPD, Pangaea) and 10 % were contributions of the original data gatherers, while a few were digitized from publications. Most of the pollen records originate from peatlands (48 %) and lake sediments (33 %). Most of the records (83 %) have ≥ 3 dates allowing the establishment of reliable chronologies. The dataset can be used for various purposes including pollen data mapping (example maps for Larix at selected time-slices are shown) as well as quantitative climate and vegetation reconstructions. The datasets for pollen counts and pollen percentages are available at https://doi.pangaea.de/10.1594/PANGAEA.898616 (Cao et al., 2019).
Mapping long-term evapotranspiration losses in the catchment of the shrinking Lake Poopó
Authors: Torres-Batlló Juan , Martí-Cardona Belén , Pillco-Zolá Ramiro
Published: May 2019

Abstract. Lake Poopó is located in the Andean Mountain Range Plateau or Altiplano. A generalised decline in the lake water level has been observed since 2001, coinciding roughly with an intensification of agriculture exploitations such as quinoa crops. Several factors have been blamed for the lake recession, including climate change, increased farming, mining abstractions and population growth. Being an endorheic catchment, evapotranspiration (ET) losses are expected to be the main water output mechanism. This study used a time series of more than 1000 satellite data based products to map ET and vegetation index trends in the Poopó catchment between 2001 and 2014. The aim was to explore the links between ET, vegetation, land use and the lake recession. The years 2015 and 2016 were excluded of the analysis due to the strong impact of El Niño phenomenon over the study area, which could have masked long term temporal trends related to land use. We quantified the ET losses and vegetation indices for the main cover types in the Poopó catchment and their temporal trends in the study period. It became obvious that cultivated areas were the ones which had experienced the largest increase in water consumption, although they were not in all instances the land covers with the largest losses. This quantification provides essential information for the sustainable planning of water resources and land uses in the catchment. We also collected on-site and satellite precipitation data. When integrated over the entire catchment, the overall ET losses showed a sustained increasing trend at an average rate of 3.2 mm yr−1. Rainfall water inputs followed a similar trend, with a slightly higher increasing rate of 5.2 mm yr−1. Based on these results and from the point of view of the catchment water balance, the ET loss intensification derived from crop expansion has been compensated by the increase in precipitation. Consequently, this study found no clear link between the agriculture intensification and the Lake Poopó recession in the analysed period.
Statistical characteristics of raindrop size distribution during rainy
seasons in Beijing urban area and implications for radar rainfall
estimation
Authors: Ma Yu , Ni Guangheng , Chandrasekar V. , Tian Fuqiang , Chen Haonan
Published: May 2019

Abstract. Raindrop size distribution (DSD) information is fundamental in understanding the precipitation microphysics and quantitative precipitation estimation, especially in complex terrain or urban environment which is known for its complicated rainfall mechanism and high spatial and temporal variability. In this study, the DSD characteristics of rainy seasons in Beijing urban area are extensively investigated using 5-year DSD observations from a Parsivel2 disdrometer located at Tsinghua University. The results show that the DSD samples with rain rate < 1 mm h−1 account for more than half of total observations. The mean values of log10 Nw and Dm of convective rain are higher than that of stratiform rain, and there is a clear boundary between the two types of rain in terms of the scattergram of log10Nw versus Dm. The convective rain in Beijing is neither continental nor maritime owing to the particular location and local topography. As the rainfall intensity increases, the DSD spectra become higher and wider, but they still have peaks around diameter D ~ 0.5 mm. The midsize drops contribute most towards accumulated rainwater. The Dm and log10Nw values show a diurnal cycle and an annual cycle. In addition, DSD shows higher Dm values and lower log10Nw values during the periods of strong urban heat island (UHI) effect and UHI up stage of a day, and the same in July and August. The localized radar reflectivity (Z) and rain rate (R) relations (Z = aRb) show substantial differences compared to the commonly used NEXRAD relationships. And the polarimetric radar algorithms R(Kdp), R(Kdp, ZDR), and R(ZH, ZDR) show greater potential for rainfall estimation.
Beyond binary baseflow separation: delayed flow index as a fresh perspective on streamflow contributions
Authors: Stoelzle Michael , Schuetz Tobias , Weiler Markus , Stahl Kerstin , Tallaksen Lena M.
Published: May 2019

Abstract. Understanding components of the total streamflow is important to assess the ecological functioning of rivers. Binary or two-component separation of streamflow into a quick- and slow (often referred to as baseflow) component, and the associated and often used baseflow index (BFI), have been criticised for their arbitrary choice of separation parameters. These methods also merge different delayed components in one baseflow component. As streamflow generation during dry weather often results from drainage of multiple sources, we propose a novel delayed flow index (DFI) considering the dynamics of multiple delayed contributions to streamflow. The DFI is based on characteristic delay curves where the identification of breakpoint estimates helps to avoid rather arbitrary separation parameters and allows distinguishing four types of delayed streamflow contributions. The methodology is illustrated using streamflow records from a set of 60 headwater catchments in Germany and Switzerland covering a pronounced elevational gradient of roughly 3000 m. We found that the quickflow signal often diminishes earlier than given by BFI-analyses with only two flow components, and further distinguished a variety of flow contributions with delays shorter than 60 days controlling the seasonal streamflow dynamics. For streamflow contributions with delays longer than 60 days, the method was used to assess catchments’ water sustainability during dry spells. Colwells’s Predictability, a measure of streamflow periodicity and sustainability, was applied to attribute the identified delay patterns to streamflow dynamics and catchment storages. The smallest storages were consistently found for catchments between approx. 800 and 1800 m a.s.l. Above an elevation of 1800 m the DFI suggests that seasonal snowpack provides the primary contribution, whereas below 800 m groundwater resources are the major streamflow contributions. Our analysis also indicates that subsurface storage in high alpine catchments may be large and is overall not smaller than in lowland catchments. The DFI can be used to assess the range of sources forming catchments’ storages and judge their long-term sustainability of streamflow. Combining the DFI with a low flow stability index, allows us to better understand controls of seasonal low flow regimes across different regimes.
Initial Assessment of Landslide Prone Area using Soil Properties

Published: May 2019

Abstract. Initial assessment of landslide prone area is important in designing landslide mitigation measures. This study, a part of our study on developing landslide spatial model, presents initial signal of landslide prone area. In here, we use soil depth to hardpan to assess landslide prone area in Western Central Java, a relatively small region where 23 % of Indonesian landslide occurs. To this end, we interpolated soil depth to hardpan in a regular grid from irregularly distributed data. To do this, we employed three different methods: Inverse Distance Weighting (IDW), Ordinary Kriging (OK) and Co-Kriging (CK). For the latter, we experimented with several potential covariates. To determine the best fitting model, several tests on model performance and its corresponding errors were done. Error measures used in this study are Mean Square Error (MSE), Root Mean Square Error (RMSE), Mean Absolute Error (MAE) and Mean Absolute Percentage Error (MAPE), while statistical measures employed are Standard Deviation, Variance, Interquartile Range (IQR), Mean Absolute Deviation and Median Absolute Deviation. The result shows that CK with covariate of slope and soil cohesion is the best fitting model and exhibits clear pattern related to recorded landslide disaster sites. We found that 64 % of landslide disaster events occur in the area having soil depth to hardpan of 5–10 m. Moreover, 84 % of landslide occurrences happen in regions where soil depth to hardpan ranges from 5 to 15 m. Hence, we suggest that landslide prone area is an area possessing soil depth to hardpan of 5–15 m. This finding is advantageous for policy makers in planning and designing efforts for landslide mitigation.
More accurate aeroelastic wind-turbine load simulations using detailed inflow information
Authors: Pedersen Mads Mølgaard , Larsen Torben Juul , Madsen Helge Aagaard , Larsen Gunner Christian
Published: May 2019

Abstract. In this paper, inflow information is extracted from a measurement database and used for
aeroelastic simulations to investigate if using more accurate inflow
descriptions improves the accuracy of the simulated wind-turbine fatigue
loads. The inflow information is extracted from nearby meteorological masts (met masts) and a
blade-mounted five-hole pitot tube. The met masts provide
measurements of the inflow at fixed positions some distance away from the turbine, whereas the
pitot tube measures the inflow while rotating with the rotor. The met mast measures the free-inflow velocity; however the measured
turbulence may evolve on its way to the turbine, pass beside the
turbine or the mast may be in the wake of the turbine. The inflow measured
by the pitot tube, in comparison, is very representative of the wind
that acts on the turbine, as it is measured close to the blades and also includes
variations within the rotor plane. Nevertheless, this inflow is
affected by the presence of the turbine; therefore, an aerodynamic model
is used to estimate the free-inflow velocities that would have occurred at the
same time and position without the presence of the turbine. The inflow information used for the simulations includes the mean wind speed
field and trend, the turbulence intensity, the wind-speed shear profile,
atmospheric stability-dependent turbulence parameters, and the azimuthal
variations within the rotor plane. In addition, instantaneously measured wind
speeds are used to constrain the turbulence. It is concluded that the period-specific turbulence intensity must be used in
the aeroelastic simulations to make the range of the simulated fatigue loads
representative for the range of the measured fatigue loads. Furthermore, it
is found that the one-to-one correspondence between the measured and
simulated fatigue loads is improved considerably by using inflow
characteristics extracted from the pitot tube instead of using the
met-mast-based sensors as input for the simulations. Finally, the
use of pitot-tube-recorded wind speeds to constrain the inflow turbulence is
found to significantly decrease the variation of the simulated loads due to
different turbulence realizations (seeds), whereby the need for multiple
simulations is reduced.
Identification and antibiotic susceptibility of bacterial microbiota of freshwater fish
Authors: Klūga Alina , Kačániová Miroslava , Terentjeva Margarita
Published: May 2019

The fish meat is an essential part of human diet. However, fish may be contaminated with different microorganisms, including pathogens. Antimicrobial resistance of fish microbiota may facilitate the spread of resistant microorganisms causing serious consequences for human health. The aim of the present study was to detect bacterial contamination in fish gill, gut and skin and to determine antimicrobial susceptibility of the bacterial isolates. Rainbow trout (Oncorhynchus mykiss) and bream (Abramis bram) were obtained from the market in Jelgava city. Chub (Leuciscus cephalus), crucian carp (Carassius carassius) and tench (Tinca tinca) were collected from fishermen. Fish samples were examined for the total bacterial count (TBC), coliforms, Enterobacteriaceae, Pseudomonas spp. and Aeromonas spp. Testing was done in accordance with International Organization for Standardization (ISO) standards. Identification of all bacteria was accomplished with the Matrix Assisted Laser Desorption Ionization – Time of Flight Mass Spectrometry (MALDI-TOF MS) method. The disc diffusion method was used for the detection of antibiotic susceptibility of isolated bacterial species. TBC ranged from 2.70 to 7.00 log CFU.g-1, coliforms from 0 to 2.67 log CFU.g-1, Enterobacteriaceae from 0 to 2.85 log CFU.g-1. The highest contamination with Pseudomonas spp. and Aeromonas spp. was observed in chub gut samples with 1.60 log CFU.g-1 and 2.23 log CFU.g-1, respectively. Altogether, 16 microbial genera and 31 bacterial species were identified. The dominant bacterial species belonged to Pseudomonas spp. (54%) and Enterobacteriaceae. Pseudomonas spp. were resistant to ticarcillin, susceptibility to ciprofloxacin showed 88% of isolates. All Enterobacteriaceae isolates were susceptible to imipenem.

Authors: Woudenberg Jan , Van der Hel - van Dijk Lisette , Kamerling Robert
Published: May 2019

In this study, we discuss if the current (international) regulatory framework regarding accounting and auditing provides an adequate basis for both company management and the auditor to report (accurately and informatively) on going concern.Overall findings indicate that from a theoretical perspective the changes made in the design of the framework since the last global economic crisis contribute to more accurate and informative reporting on going concern. This starts with an increased focus on substantiated reporting on long-term value creation and continuity in the U.K. and Dutch corporate governance codes. Furthermore, the current Dutch and U.S. accounting standards increasingly pay attention to reporting on going concern. Also several changes in the Dutch, international and (partly) U.S. auditing standards could have a positive impact, such as the requirement to state the responsibilities of both company management and the auditor in each auditor’s report, and the introduction of key audit matters offering the possibility to report on going concern risks and the audit procedures performed.There is, however, still room for improvement. It seems that various standard setters have determined their own route and pace, which may have kept them from implementing more progressive proposals such as a conclusion and a statement on going concern in each auditor’s report. As a result, the exception-based reporting model is still largely retained. Further progress can be made by implementing a so-called holistic approach to ensure that the responsibilities of company management and the auditor are aligned, and by striving for more international convergence.

The purpose of this study is to analyse the happiness and life satisfaction levels of university students by various factors and to reveal the relationship between those two terms. The sample group of the study is composed of Necmettin Erbakan University Physical Education and Sports Teacher Department and Pamukkale University Sports Sciences Faculty students, who are 801 in number, 394 of them male and 407 of them female, and with an average age of 23.58±2.98. In the study the “Life Satisfaction Scale,” which has been developed by Diener et al. (1985) and adapted to Turkish by Durak et al. (2010), and the “Oxford Happiness Scale Short Version,” which has been developed by Hills and Argyle (2002) and adapted to Turkish by Doğan and Akıncı Çötok (2010), has been used. To determine the personal information distribution of participants percentage and frequency methods, and to determine whether the data has normal distribution or not Shapir Wilks normalcy test has been used and after establishing that the data is suitable for parametric test conditions, to analyse the data the independent t Test, Anova and Pearson Correlation tests have been used. According to the analysis results, a significant difference in life satisfaction has been observed with respect to age and regular exercise parameters (p < 0.05). According to the happiness scale a significant difference has been observed with respect to gender, department, grade and department satisfaction parameters (p < 0.05). Finally, a positive and meaningful relationship has been observed between the two scales. Consequently, it could be argued that life satisfaction and happiness levels of participants show significant differences with respect to some parameters and that the higher their life satisfaction, the higher their level of happiness.

As contaminações das águas superficiais por antibióticos vêm causando um efeito negativo de longo prazo para a sustentabilidade ecológica prejudicando a vida aquática e a saúde humana. Neste contexto, a biossorção se configura como uma alternativa promissora para a remediação dessas águas contaminadas. Este trabalho teve como objetivo avaliar o melhor tratamento químico em relação à capacidade de adsorção da amoxicilina e da cefalexina pelo epicarpo do açaí. Inicialmente, foi determinado o ponto de carga zero (pHpcz) do biossorvente, logo após, realizaram-se testes de adsorção em diferentes pHs (3, 5, 7 e 9) com diferentes tratamentos (H3PO4 e NaOH (0,5 mol L-1)). A impregnação do material adsorvente com o ativador químico ocorreu na proporção de 10 gramas de sólido por litro de solução, a mistura foi aquecida a 80 °C por 30 minutos e desidratado a 110 °C. Após 24 h, lavou-se o material com água destilada, a 100 °C, até a estabilização do pH e posteriormente secagem à 110 °C. Os resultados obtidos demonstraram que o (pHpcz) do biossorvente, com tratamento básico, foi de 5,9. O açaí com tratamento básico apresentou maior teor de remoção 95% para a cefalexina no pH 5. Verificou-se assim que a adsorção foi favorecida com o tratamento básico fazendo com que a carga superficial do biossorvente torna-se mais negativa, alterando o pH do açaí. Portanto, evidencia-se o ótimo potencial do epicarpo de açaí na remoção da cefalexina.

The search for sustainable fuels has become important for the development of energy generation in balance with the environment. Brazil has climatic conditions and a vast territory for the production of forest biomass. The research produced in the laboratory determines the gravimetric yield, upper calorific value, percentages of fixed carbon, volatile and ashes of the charcoals of bamboo species: Bambusa vulgaris var vittatta, Dendrocalamus asper and Phyllostachys pubescens. For the carbonization process, small pieces of bamboo were obtained, were dried in the stove at 100°C for 24 hours, the dried mass was weighed and added in a carbonizer heated to 150°C for 45 minutes, heated to 180°C for 45 minutes and heated to 210°C for 30 minutes, this charcoal was then cooled and  weighed to calculate the gravimetric yield. The samples were pulverized in a pot mill, the upper calorific value in a calorimeter was determined. The volatile, fixed carbon and ash contents were determined according to the Brazilian MB-15 method. The results obtained for the species B. vittatta, D. asper and P. pubescens, were respectively: gravimetric yield 44.08%, 42.77% and 47.09%; calorific value 28.806kJ/g, 29.075kJ/g and 28.489kJ/g; percentage of fixed carbon 62.1%, 66.09% and 57.8%; percentage of volatiles 35.89%, 30.92% and 40.4%; ash percentage 2.01%, 2.99% and 1.8%. It was observed that the D. asper specie presented better results in the general context of the analysis carried out because, despite presenting a slightly lower gravimetric yield, it presented the higher calorific value and higher fixed carbons content.

The objective of this project was to obtain the temperature profile formed in the wood during the slow pyrolysis process. For this, small holes were opened into the wood using a drill, three thermocouples were inserted in the radial portion along the length of the wood and on the surface - center direction. Three Eucalyptus wood logs, 35 cm long, 30% moisture and 8, 9 and 12 cm diameters, were used. The final pyrolysis temperature was 400 °C. The gravimetric yield of the products was calculated after the pyrolysis process.  The formation of thermal gradients was observed in the wood throughout the process. The temperature difference between the surface and the center can reach up 200 °C, in the pyrolysis of the largest diameter wood.  Thermal heights formed in the wood at 100 °C were detected, being more evident in the central portion. The thermal variation perceived in the wood can be explained by the presence of water, which demands energy for its evaporation and changes the temperature gradients, and the heat conductivity is poor due to the wood being a porous material, mainly in the carbonized zone.These phenomena influence the heat transfer during the pyrolysis process. On the surface - to - center direction, the formation of temperature gradients generates transient thermal threshold due to the drying process. Thus, a temperature gradient was formed between the surface and the center of the wood during the pyrolysis and the total time of the process will be higher in the largest diameter wood.

The Need to Suffer: The Case of Poland
Authors: Zechenter Katarzyna
Published: May 2019

This article explores the construction and various representations of Polish collective suffering and victimhood in Polish literature. It argues that the loss of independence (1795–1918) and the subsequent struggles to regain it can be read as Poland’s most important cultural trauma that heavily marked Polish identity. It discusses how the paradigm was created and established, as well as the unsuccessful struggle with the paradigm of suffering over the subsequent years. Overall, it argues that literature after 1945 lost its power over the national imagination as Polish identity is no longer bound by the past representations of suffering.

Published: May 2019

The purpose of this study is to investigate the influence of knowledge sharing (KS) and two specific types of innovation on competitive advantage in Vietnamese firms. Based on using structural equation modeling (SEM) and survey data collected from 225 participants, the findings reveal that KS directly and indirectly affects firm’s competitive advantage through the mediating role of innovation speed and innovation quality. The findings stress the important role of building a positive climate to stimulate employees for sharing knowledge aimed at improving firm’s innovation capability, and sustaining competitive advantage. Future research needs to explore the relationship between three components of knowledge management namely knowledge acquisition, KS, and knowledge application, innovation, and specific aspects of competitive advantage (such as low cost advantage, differentiation advantage, and time advantage) to provide deeper the mechanism of how specifics aspects of knowledge management connected with firm’s certain types of competitive advantage through innovation.
