Radiative effects of long-range-transported Saharan air layers as determined from airborne lidar measurements
Authors: Gutleben Manuel , Groß Silke , Wirth Martin , Mayer Bernhard
Published: October 2020

Abstract. The radiative effect of long-range-transported Saharan air layers is investigated on the basis of simultaneous airborne high-spectral-resolution and differential-absorption lidar measurements in the vicinity of Barbados.
Within the observed Saharan air layers, increased water vapor concentrations compared to the dry trade wind atmosphere are found.
The measured profiles of aerosol optical properties and water vapor mixing ratios are used to characterize the atmospheric composition in radiative transfer calculations, to calculate radiative effects of moist Saharan air layers and to determine radiative heating rate profiles.
An analysis based on three case studies reveals that the observed enhanced amounts of water vapor within Saharan air layers have a much stronger impact on heating rate calculations than mineral dust aerosol.
Maximum mineral dust short-wave heating and long-wave cooling rates are found at altitudes of highest dust concentration (short wave: +0.5 K d−1; long wave: −0.2 K d−1; net: +0.3 K d−1).
However, when considering both aerosol concentrations and measured water vapor mixing ratios in radiative transfer calculations, the maximum heating/cooling rates shift to the top of the dust layer (short wave: +2.2 K d−1; long wave: −6.0 to −7.0 K d−1; net: −4.0 to −5.0 K d−1).
Additionally, the net heating rates decrease with height – indicating a destabilizing effect in the dust layers.
Long-wave counter-radiation of Saharan air layers is found to reduce cooling at the tops of the subjacent marine boundary layers and might lead to less convective mixing in these layers.
The overall short-wave radiative effect of mineral dust particles in Saharan air layers indicates a maximum magnitude of −40 W m−2 at surface level and a maximum of −25 W m−2 at the top of the atmosphere.

Published: October 2020

Abstract. Large uncertainties exist in global climate model predictions of radiative forcing due to insufficient understanding and simplified numerical representation of cloud formation and cloud-aerosol interactions. The Holistic Interactions of Shallow Clouds, Aerosols and Land Ecosystems (HI-SCALE) campaign was conducted near the DOE's Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) site in north-central Oklahoma to provide a better understanding of land-atmosphere interactions, aerosol and cloud properties, and the influence of aerosol and land-atmosphere interactions on cloud formation. The HI-SCALE campaign consisted of two Intensive Observational Periods (IOPs) (April–May, and August–September, 2016), during which coincident measurements were conducted both on the G-1 aircraft platform and at the SGP ground site. In this study we focus on the observations at the SGP ground site. An Aerodyne HR-ToF Aerosol Mass Spectrometer (AMS) and an Ionicon Proton-Transfer-Reaction Mass Spectrometer (PTR-MS) were deployed, characterizing chemistry of non-refractory aerosol and trace gases, respectively. Contributions from various aerosol sources, including biogenic and biomass burning emissions, were retrieved using factor analysis of the AMS data. In general, the organic aerosols at the SGP site was highly oxidized, with OOA identified as the dominant factor for both the spring and summer IOP though more aged in spring. Cases of IEPOX SOA and biomass burning events were further investigated to understand additional sources of organic aerosol. Unlike other regions largely impacted by IEPOX chemistry, the IEPOX SOA at SGP was more highly oxygenated, likely due to the relatively weak local emissions of isoprene. Biogenic emissions appear to largely control the formation of OA during HI-SCALE campaign. Potential HOM (highly-oxygenated molecule) chemistry likely contributes to the highly-oxygenated feature of aerosols at the SGP site, with impacts on new particle formation and global climate.
ENSO Effect on Interannual Variability of Spring Aerosols over
East Asia
Authors: Zhu Anbao , Xu Haiming , Deng Jiechun , Ma Jing , Li Shuhui
Published: October 2020

Abstract. Effects of the El Niño/Southern Oscillation (ENSO) on the interannual variability of spring aerosols over East Asia are investigated using the Modern Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) reanalysis aerosol data. Results show that the ENSO has a crucial effect on the spring aerosols over the Indochina Peninsula, southern China and the ocean south of Japan. The above-normal (below-normal) aerosols are found over these regions during the El Niño (La Niña) ensuing spring. In contrast to the local aerosol diffusion in winter, the ENSO affects East Asian aerosols in the following spring mainly via modulating upstream aerosol generation and transport processes. The underlying physical mechanism is that during the El Niño (La Niña) ensuing spring, the dry (wet) air and less (more) precipitation are beneficial for the increase (reduction) of biomass burning activities over the northern Indochina Peninsula, resulting in more (less) carbonaceous aerosol emissions. On the other hand, the anomalous anticyclone (cyclone) over the western North Pacific (WNP) associated with El Niño (La Niña) enhances (weakens) the low-level southwesterly wind from the northern Indochina Peninsula to southern Japan, which transports more (less) carbonaceous aerosol downstream. Anomalous precipitation plays a role in reducing aerosols over the source region, but its washout effect over the downstream region is limited. The ENSO’s impact on the ensuing spring aerosols is mainly attributed to the eastern Pacific ENSO rather than the central Pacific ENSO.
A revised mineral dust emission scheme in GEOS-Chem:
improvements in dust simulations over China
Authors: Tian Rong , Ma Xiaoyan , Zhao Jianqi
Published: October 2020

Abstract. Mineral dust plays a significant role in climate change and air quality, but large uncertainties remain in terms of dust emission prediction. In this study, we improved the treatments of dust emission process in a Global 3-D Chemical Transport model (GEOS-Chem) v12.6.0, by incorporating the geographical variation of aerodynamic roughness length (Z0), smooth roughness length (Z0s), soil texture, introducing Owen effect and Lu and Shao (1999) formulation of sandblasting efficiency α. To investigate the impact of the modifications incorporated in the model, several sensitivity simulations were performed for a severe dust storm during March 27, 2015 to April 2, 2015 over northern China. Results show that simulated threshold friction velocity is very sensitive to the updated Z0 and Z0s field, with the relative difference ranging from 10 % to 60 % compared to the original model with uniform value. An inclusion of Owen effect leads to an increase in surface friction velocity, which mainly occurs in the arid and semi-arid regions of northwest China. The substitution of fixed value of α assumed in original scheme with one varying with friction velocity and soil texture based on observations reduces α by 50 % on average, especially over regions with sand texture. Comparisons of sensitivity simulations and measurements show that the revised scheme with the implement of updates provides more realistic threshold friction velocities and PM10 mass concentrations. The performance of the improved model has been evaluated against surface PM10 observations as well as MODIS aerosol optical depth (AOD) values, showing that the spatial and temporal variation of mineral dust are better captured by the revised scheme. Due to the inclusion of the improvement, average PM10 concentrations at observational sites are more comparable to the observations, and the average mean bias (MB) and normalized mean bias (NMB) values are reduced from −196.29 μg m−3 and −52.79 % to −47.72 μg −3 and −22.46 % respectively. Our study suggests that the erodibility factor, sandblasting efficiency and soil-related properties which are simply assumed in the empirical scheme may lack physical mechanism and spatial-temporal representative. Further study and measurements should be conducted to obtain more realistic and detailed map of these parameters in order to improve dust representation in the model.
Measurement of NOx and NOy with a thermal dissociation cavity ring-down spectrometer (TD-CRDS): instrument characterisation and first deployment

Published: October 2020

Abstract. We present a newly constructed, two-channel thermal
dissociation cavity ring-down spectrometer (TD-CRDS) for the measurement of
NOx (NO+NO2), NOy (NOx+HNO3+RO2NO2+2N2O5 etc.), NOz (NOy−NOx)
and particulate nitrate (pNit). NOy-containing trace gases are detected
as NO2 by the CRDS at 405 nm following sampling through inlets at ambient
temperature (NOx) or at 850 ∘C (NOy). In both cases,
O3 was added to the air sample directly upstream of the cavities to
convert NO (either ambient or formed in the 850 ∘C oven) to
NO2. An activated carbon denuder was used to remove gas-phase
components of NOy when sampling pNit. Detection limits, defined as the
2σ precision for 1 min averaging, are 40 pptv for both NOx
and NOy. The total measurement uncertainties (at 50 % relative humidity, RH) in the
NOx and NOy channels are 11 %+10 pptv and 16 %+14 pptv
for NOz respectively. Thermograms of various trace gases of the
NOz family confirm stoichiometric conversion to NO2 (and/or NO)
at the oven temperature and rule out significant interferences from NH3
detection (<2 %) or radical recombination reactions under
ambient conditions. While fulfilling the requirement of high particle
transmission (>80 % between 30 and 400 nm) and essentially
complete removal of reactive nitrogen under dry conditions (>99 %), the denuder suffered from NOx breakthrough and memory effects
(i.e. release of stored NOy) under humid conditions, which may
potentially bias measurements of particle nitrate. Summertime NOx measurements obtained from a ship sailing through the
Red Sea, Indian Ocean and Arabian Gulf (NOx levels from <20 pptv to 25 ppbv) were in excellent agreement with those taken by a
chemiluminescence detector of NO and NO2. A data set obtained locally
under vastly different conditions (urban location in winter) revealed large
diel variations in the NOz to NOy ratio which could be
attributed to the impact of local emissions by road traffic.
Methane paradox in tropical lakes? Sedimentary fluxes rather than pelagic production in oxic conditions sustain methanotrophy and emissions to the atmosphere

Abstract. Despite growing evidence that methane (CH4) formation could
also occur in well-oxygenated surface fresh waters, its significance at the
ecosystem scale is uncertain. Empirical models based on data gathered at
high latitude predict that the contribution of oxic CH4 increases with
lake size and should represent the majority of CH4 emissions in large
lakes. However, such predictive models could not directly apply to tropical
lakes, which differ from their temperate counterparts in some fundamental
characteristics, such as year-round elevated water temperature. We conducted
stable-isotope tracer experiments, which revealed that oxic CH4
production is closely related to phytoplankton metabolism and is a common
feature in five contrasting African lakes. Nevertheless, methanotrophic
activity in surface waters and CH4 emissions to the atmosphere were
predominantly fuelled by CH4 generated in sediments and physically
transported to the surface. Indeed, CH4 bubble dissolution flux and
diffusive benthic CH4 flux were several orders of magnitude higher than
CH4 production in surface waters. Microbial CH4 consumption
dramatically decreased with increasing sunlight intensity, suggesting that
the freshwater “CH4 paradox” might be also partly explained by
photo-inhibition of CH4 oxidizers in the illuminated zone. Sunlight
appeared as an overlooked but important factor determining the CH4
dynamics in surface waters, directly affecting its production by
photoautotrophs and consumption by methanotrophs.
SoilErosionDB: A global database for surface runoff and soil
erosion evaluation

Published: October 2020

Abstract. Soil erosion is a major threat to soil resources, continuing to cause environmental degradation and social poverty in many parts of the world. Many field and laboratory experiments have been performed over the past century to study spatio-temporal patterns of soil erosion caused by surface runoff under different environmental conditions. However, these historical data have never been integrated together in a way that can inform current and future efforts to understand and model soil erosion at different scales. Here, we designed a database (SoilErosionDB) to compile field and laboratory measurements of soil erosion caused by surface runoff, with data coming from sites across the globe. The SoilErosionDB includes 18 columns for soil erosion related indicators and 73 columns for background information that describe factors such as latitude, longitude, climate, elevation, and soil type. Currently, measurements from 99 geographic sites and 22 countries around the world have been compiled into SoilErosionDB. We provide examples of linking SoilErosionDB with an external climate dataset and using annual precipitation to explain annual soil erosion variability under different environmental conditions.

The Effects of Ocean Surface Waves on Global Forecast
in CFS Modeling System v2.0
Authors: Shi Ruizi , Xu Fanghua , Liu Li , Fan Zheng , Yu Hao , Li Xiang , Zhang Yunfei
Published: October 2020

Abstract. It has been well known that ocean surface gravity waves have enormous effects on physical processes at the atmosphere–ocean interface. However, the effects of surface waves on global forecast in several days are less studied. To investigate this, we incorporated the WAVEWATCH III model into the Climate Forecast System Model version 2.0 (CFS2.0), with the Chinese Community Coupler version 2.0 (C-Coupler2). Two major wave-related processes, the Langmuir mixing and the sea surface momentum roughness, were considered. Extensive comparisons were performed against in-situ buoys, satellite measurements and reanalysis data, to evaluate the influence of the two processes on the forecast of sea surface temperature, mixed layer depth, significant wave height, and 10-m wind speed. A series of 7-day simulations demonstrate that the newly developed atmosphere-ocean-wave coupling system could improve the CFS global forecast. The Langmuir mixing parameterization could increase the vertical movement of water and effectively reduce the warm bias of sea surface temperature and shallow bias of mixed layer depth in the Antarctic circumpolar current in austral summer, whereas the significant wave height and 10-m wind speed are insensitive to it. On the other hand, the modified momentum roughness length could significantly reduce the overestimated 10-m wind speed and significant wave height in mid-high latitudes. This is because the enhanced frictional dissipation at high wind speed could reduce 10-m wind speed and consequently decrease the significant wave height. But its effect on the temperature structure in upper ocean is less obvious.
Oxidation of low-molecular weight organic compounds in cloud
droplets: development of the JAMOC chemical mechanism in
CAABA/MECCA (version 4.5.0gmdd)
Authors: Rosanka Simon , Sander Rolf , Wahner Andreas , Taraborrelli Domenico
Published: October 2020

Abstract. The Jülich Aqueous-phase Mechanism of Organic Chemistry (JAMOC) is developed and implemented in the Module Efficiently Calculating the Chemistry of the Atmosphere (MECCA, version 4.5.0gmdd1). JAMOC is an explicit in-cloud oxidation scheme for oxygenated volatile organic compounds (OVOCs), suitable for global model applications. It is based on a subset of the comprehensive CLoud Explicit Physico-chemical Scheme (CLEPS, version 1.0). The phase transfer of species containing up to ten carbon atoms is included, and a selection of species containing up to four carbon atoms reacts in the aqueous-phase. In addition, the following main advances are implemented: (1) simulating hydration and dehydration explicitly, (2) taking oligomerisation of formaldehyde, glyoxal and methylglyoxal into account, (3) adding further photolysis reactions, and (4) considering gas-phase oxidation of new outgassed species. The implementation of JAMOC in MECCA makes a detailed in-cloud OVOC oxidation model readily available for box as well as for regional and global simulations that are affordable with modern supercomputing facilities. The new mechanism is tested inside the box-model Chemistry As A Boxmodel Application (CAABA), yielding reduced gas-phase concentrations of most oxidants and OVOCs except for the nitrogen oxides. 1 The name of this version indicates that it is used for the interactive discussion in GMDD. If necessary, bug fixes can still be made. We plan to release the final version CAABA/MECCA-4.5.0 together with the final paper in GMD.
Dynamic mechanism of an extremely severe saltwater intrusion in the Changjiang estuary in February 2014
Authors: Zhu Jianrong , Cheng Xinyue , Li Linjiang , Wu Hui , Gu Jinghua , Lyu Hanghang
Published: October 2020

Abstract. Estuarine saltwater intrusions are mainly controlled by
river discharge and tides. Unexpectedly, an extremely severe saltwater
intrusion event occurred in February 2014 in the Changjiang estuary under
normal river discharge conditions. This intrusion cut off the freshwater
input for 23 d into the Qingcaosha reservoir, which is the largest
estuarine reservoir in the world, creating a severe threat to water safety
in Shanghai. No similar catastrophic saltwater intrusion has occurred since
records of salinity in the estuary have been kept. During the event, a
persistent and strong northerly wind existed, with a maximum speed of 17.6 m s−1, lasting 9 d and coinciding with a distinct water level rise. Our study demonstrates that the extremely severe saltwater intrusion was caused by this northerly wind, which drove substantial landward net water transport to form a horizontal estuarine circulation that flowed into the northern channel and out of the southern channel. This landward net water transport overpowered the seaward-flowing river runoff and transported a
large volume of highly saline water into the northern channel. The mechanisms of this severe saltwater intrusion event, including the northerly wind,
residual water level rise, landward water transport and resulting horizontal circulation, etc., were systematically investigated.
Predictive modeling of hourly probabilities for weather-related road accidents
Authors: Becker Nico , Rust Henning W. , Ulbrich Uwe
Published: October 2020

Abstract. Impacts of weather on road accidents have been identified in several studies with a focus mainly on monthly or daily accident counts.
This study investigates hourly probabilities of road accidents caused by adverse weather conditions in Germany on the spatial scale of administrative districts using logistic regression models.
Including meteorological predictor variables from radar-based precipitation estimates, high-resolution reanalysis and weather forecasts improves the prediction of accident probability compared to models without weather information.
For example, the percentage of correctly predicted accidents (hit rate) is increased from 30 % to 70 %, while keeping the percentage of wrongly predicted accidents (false-alarm rate) constant at 20 %.
When using ensemble weather forecasts up to 21 h instead of radar and reanalysis data, the decline in model performance is negligible.
Accident probability has a nonlinear relationship with precipitation. Given an hourly precipitation sum of 1 mm, accident probabilities are approximately 5 times larger at negative temperatures compared to positive temperatures.
The findings are relevant in the context of impact-based warnings for road users, road maintenance, traffic management and rescue forces.

Published: October 2020

En la última década las formaciones han introducido espacios en sus webs dedicados a la transparencia y han trabajado en estos portales especialmente desde que se aprobó la Ley de Transparencia, que les obliga a cumplir con los compromisos de publicidad activa. Este trabajo busca conocer la forma en la que los partidos políticos organizan sus portales de transparencia, cuál es su estrategia comunicativa, así como indagar en la percepción que tienen de la situación actual del acceso a la información y la publicidad activa en este país. Para ello, se realizaron sendas entrevistas en profundidad a los responsables de transparencia del Partido Popular, el Partido Socialista, Podemos y Ciudadanos. También se entrevistó al presidente del Consejo de Transparencia, Javier Amorós. Los resultados muestran que casi todos los partidos políticos se ven superiores en transparencia, mientras que el presidente del Consejo ve la transparencia de las organizaciones como «aparente».

Relationship between the activity of guaiacol peroxidase and the content of photosynthetic pigments in tea leaves
Authors: Platonova Nataliia , Belous Oksana
Published: October 2020

The dynamics of guaiacol peroxidase and photosynthetic pigments in 3-leaf sprouts (flushes) of tea plants were studied. The presence of declines and peaks in the activity of the enzyme associated with the meteorological conditions of each month was noted. It is shown that there is a direct relationship between the increase in enzyme activity and hydrothermal factors. The most significant correlation was found between the activity of GPO in a 3-leaf tea flush and the amount of precipitation (r = 0.86). The highest activity of guaiacol peroxidase during the entire vegetation period is distinguished by the Sochi variety and form 582. The lowest activity was observed in forms 3823 and 2264, which indicates a low intensity of redox reactions in these plants in stressful situations. Determining the dynamics of the pigment complex revealed its dependence on hydrothermal factors. Studies have shown that precipitation is a significant factor affecting the pigment complex of tea plants. It was found that the largest amount of green pigments is synthesized by leaves at the beginning of active vegetation (May). The participation of the pigment apparatus in the adaptation of the tea plant is directly related to carotenoids, the increase in the number of carotenoids coincides with the period of drought. In the content of photosynthetic pigments and the activity of guaiacol peroxidase manifest genotypic features. The revealed patterns are common to all tea plants.

El tratamiento literario de la causa inmaculista en La Aurora de Cristo (1616) de Luis de Belmonte BermúdezThe Immaculate Conception in Luis de Belmonte Bermúdez’s La Aurora de Cristo (1616)
Authors: Navarro María del Rosario Martínez
Published: October 2020

Even before Philip III created the Immaculate Conception Royal Committee in 1616, a fervent promotion and defense of the dogma of Virgin Mary’s Immaculate Conception were carried out, resulting in a series of poems of circumstance devoted to this doctrine that proliferated through the Baroque period. A sample of that intense literary activity is La Aurora de Cristo, a narrative epic poem written that same year by Luis de Belmonte Bermúdez, who was from Seville. This paper focuses on this work as a reflection of a moment of maximum apogee of the Marianist spirit lived in the Andalusian city.

El objeto del presente trabajo fue estudiar la estrategia utilizada por 3 cepas de ratas albinas, grises y Hoodep (Cepa Long Evans), para localizar la comida bajo dos condiciones de motivación: un grupo fue deprivado de comida hasta llegar al 84% de su peso inicial, y el otro al 75%.En base a los resultados previamente  obtenidos en nuestro laboratorio, planteamos la hipótesis de que las ratas menos motivadas (84%) se comportan como las descritas en la literatura, es decir, entrando a los brazos de forma aleatoria, guiadas por claves visuales alocéntricas. Cuando el grado  de deprivación fuese mayor, las ratas usarían claves intralaberínticas egocéntricas y propioceptivas. Esta estrategia egocéntrica debería ser más efectiva ya que las ratas al elegir más el brazo adyacentes cometen menos errores.

This study examined the effect of administering an additional dose of prostaglandin F2 alpha (PGF2?), in a fixed-time artificial insemination protocol (FTAI), on the fertility of female Nellore cattle. Two experiments were carried out: the first (Experiment I) took place in the state of Tocantins and the second (Experiment II) in the state of Pará, Brazil. In Experiment I (E1), 80 cows were used in three treatments (T1, T2 and T3) in which all received the same FTAI protocol. In T1 (n = 29), the cows received 12.5 mg of Dinoprost on day 9; in T2 (n = 28), they received the additional dose on day 10; and in T3 (n = 23; control group), the animals did not receive the additional PGF2? dose. Experiment II consisted of 147 bovine females distributed into two treatment groups, namely, T1 - 72 animals receiving the same protocol as T1 of E1; and T2 - 75 animals receiving the same protocol as T3 of E1. Statistical analysis was performed using SAS software, applying the PROC NPARWAY procedure for E1, and means were compared by the Wilcoxon test at the 5% significance level. In Experiment II, the data were subjected to analysis of variance by PROC GLIMMIX and means were compared by the T test at the 5% significance level. The following pregnancy rates were obtained in Experiment I: T1 - 62.06% (18/29); T2 - 57.14% (16/28); and T3 - 52.17% (12/23), with no significant difference observed between treatments. In Experiment II, pregnancy rate in T1 was 66.67% (48/72), whereas in T2 it was 41.33% (31/75), with a significant difference detected (P < 0.05).

We investigated the occurrence of Cryptosporidium oocysts shedding by domestic cats in an urban setting. The calculation of minimum sample size was based on an estimated prevalence of 10%, 5% absolute sampling error and a 5% significance level, resulting in 138 cats. A total of 612 owners of 2,290 cats had to be contacted for achieving the minimal sample size. In the end, only 55 owners accepted to participate in this investigation. Stool samples collected from 138 dogs were examined by microscopy using modified Kinyoun acid-fast staining, capture ELISA and nested-PCR followed by sequencing. Samples were considered positive when Cryptosporidium were detected by at least two diagnostic methods. Thirteen samples were positive (9.4%; 95% CI: 4.5 - 14.3). Cryptosporidium amplicons from seven out of the 13 samples were successfully sequenced and shared 99% genetic similarity to Cryptosporidium felis, GenBank access AF112575.1 was found. We concluded that Cryptosporidium infection is common in domestic cats from urban area and veterinary practitioners should guide cat owners to adopt preventive measures against the parasite to reduce the chance of infection in cats and householders.
Motions of rigid bodies and criteria for overturning by earthquake excitations
Authors: Ishiyama Yuji
Published: October 2020

This investigation deals with motions of rigid bodies on a rigid floor subjected to sinusoidal and earthquake excitations, and overturning of the bodies. Experiments and simulations of frequency sweep tests were conducted, and it is concluded that the horizontal velocity as well as the acceleration must be taken into account as criteria for overturning. Simulations by earthquake excitations show that the criteria are also applicable to the earthquake excitations. Therefore it is possible to estimate the lower limits of the maximum horizontal acceleration and velocity of the input excitations, from the overturning of bodies.

Going Global: The Successful Link of IELTS and Aptis to China’s Standards of English Language Ability (CSE)
Authors: Chen Xueliang , Hu Jie
Published: October 2020

The development of a common language proficiency scale is essential to language teaching, learning, and assessment. While some general English proficiency scales already exist, no such scale is available in an Asian context. China’s Standards of English Language Ability (CSE), as the first scale of its kind, promises to address this deficiency with a clear focus on the student population, grounded in the well-established framework of communicative language ability. As such, it not only illuminates the learning patterns of English language learners at different stages, but also provides a benchmark for curriculum design, student evaluation, and the improvement of educational programs. More importantly, its recent link with such international tests as Aptis and IELTS marks a significant step towards the internationalization of this scale, making student grades on different tests more comparable. The official mapping of CSE to the international examination system opens China’s education further to the rest of the world, and would facilitate student exchanges and deepen educational ties between countries in the future.
Presupposition Use in Arabic Political Discourse: The Case of King Salman Speech on Terrorism
Authors: Youssef Sameh , Albarakati Mohammed
Published: October 2020

This paper aims at investigating presupposition use in Arabic political discourse. The study attempts to answer the feasibility of using presupposition as a convincing tool in Arabic political discourse. The study adopts the Accommodation Analysis model, as examples from the speech of Saudi King Salman bin Abdulaziz on terrorism in 2017 are analyzed from two perspectives: Speaker presupposition perspective and Utterance presupposition perspective. The analysis found that using the Speaker presupposition perspective, presuppositions can pass unblocked, and when a plug exists, the local context creates a hole so that the presupposition can be accommodated successfully. The analysis stresses the value of context to accommodate presuppositions when they encounter projection problems. Presuppositions are more likely blocked when the Utterance presupposition perspective is adopted because different groups may have different interpretations. The findings of the study stress that sharing knowledge, i.e., political beliefs in the context of the study, is vital for a presupposition to pass unblocked.

Success of cowpea cultivation requires a strong understanding of production constraints in order to overcome them. It is thus useful to know whether smallholder cowpea growers use modern or indigenous means to overcome these challenges. We completed a participatory rural appraisal (PRA) study to identify current cowpea production constraints and management practices in Burkina Faso. We interviewed 481 cowpea growers (219 women and 262 men) and used a mixed-method design of collecting both qualitative and quantitative data. The results showed that water scarcity, damage due to insects, plant diseases, striga, lack of training, and marketing challenges are the main constraints to cowpea production. Among insects reducing cowpea yield, growers identified aphids as a major pest. However, growers often did not know the biology and incidence of insects in their fields. This study also identified local resistant cowpea varieties in various locations.
Experiência estética e escola: cartografia dos encontros com a infância e a arte nos anos iniciais do ensino fundamental

Published: October 2020

Este estudo é parte de uma pesquisa mais ampla, que encontrou com a infância, a arte e a experiência estética nos anos iniciais do Ensino Fundamental e as convidou para uma caminhada, sobretudo, com crianças no “espaçotempo” escolar. De modo geral, a pesquisa buscou cartografar os (des)encontros (im)possíveis da infância, da arte e da experiência estética na escola. No entanto, o presente artigo destaca, em específico, os (des)encontros (im)possíveis da experiência estética na escola. Considera a experiência estética como uma relação mais ampla e sensível com o mundo, conforme indicam Guedes e Ferreira (2017), e destaca os desafios postos pela modernidade para que tal relação aconteça, como colocado por Pedro Pagni (2014). A pesquisa foi realizada junto a 41 (quarenta e uma) crianças e 06 (seis) professoras de uma escola pública a partir de um plano comum e heterogêneo de produção de dados inspirado na cartografia. Os dados indicam, dentre outros descobertas, a cópia e o silêncio como parte do projeto moderno de redução da experiência estética e destaca as transformações disparadas pelas crianças através da escrita, do desenho e da conversa como (r)existência alternativa ao referido projeto na escola. Desse modo, os (des)encontros (im)possíveis da experiência estética destacados desfalecem todo saber e poder totalitários, a experiência estética parece soprar vida à escola, animar-lhe.
Circular Economy and Industry 4.0: One-Way or Two-way Relationships?
Authors: Ćwiklicki Marek , Wojnarowska Magdalena
Published: October 2020

The ability of Industry 4.0 to help solve complex economic and social problems and implement complex concepts is assessed. Currently, one of the greatest challenges is the integration of the circular economy (CE) into real business practices. However, the link between these two ideas is not fully recognised, causing an interpretative dilemma. Therefore, the aim of this paper is to identify the relationships between the CE and Industry 4.0. For this purpose, we performed a systematic literature review and content analysis of selected articles indexed in Scopus, Web of Science, ScienceDirect, and EBSCO. In total, 32 papers published during the period 2017-2020 were analysed. The findings show a one-way relationship, i.e., Industry 4.0 leads to a CE, and a two-way relationship, indicating synergy between these concepts. The key spheres of the CE in terms of Industry 4.0 are the recycle and reuse strategy applied in smart production and a sustainable supply chain. This study demonstrates the importance of company (micro) and industry (meso) levels as application areas. The most promising digitalisation tools of Industry 4.0 are the Internet of Things (IoT) and Big Data Analytics. The article concludes with the limitations of the study and a formulation of directions for future research.

Background: Detecting early predictors of acute pyelonephritis (APN) is essential for the prognosis, but few studies have focused on young infants specifically. Objectives: The aim of our research was to determine the relationship between APN and laboratory parameters in the age group less than 4 months. Methods: This retrospective study included patients aged less than 4 months with first time febrile urinary tract infection (UTI) between January 2012 and December 2018. White blood cells (WBC), C-reactive protein (CRP), and blood neutrophil/lymphocyte ratio (NLR) were analyzed. Patients were divided into two groups according to the presence of renal defects on dimercaptosuccinic acid (DMSA) scans. Results: In total, 205 patients were screened; 107 patients were in the APN group, and 98 patients were in the non-APN group. Compared with the non-APN group, the APN group showed significant differences in therapeutic response time (TRT), CRP, and NLR (all P values < 0.001). Multiple logistic regression analysis revealed that CRP, NLR, and TRT were independent risk factors for APN (P ≤ 0.001, 0.003, and 0.004, respectively). The area under the receiver operating characteristic (ROC) curve was 0.774 for CRP (P < 0.001). The optimum cut-off value for CRP was 4.27 mg/dL, with the highest sensitivity and specificity (70.1% and 73.5%, respectively). Conclusions: In the age group less than 4 months, without the image diagnosis, we could treat the patients as APN for longer antibiotic duration if CRP ≥ 4.27 mg/dL.
