Geoquímica de las rocas plutónicas del batolito cambro-ordovícico del Cordón de Lila y de la Sierra de Almeida, Región de Antofagasta, Chile
Authors: Niemeyer Rubilar Hans
Published: October 2020

An Upper Cambrian-Ordovician (490-460 Ma) batholith crop out along the Cordón de Lila and Sierra de Almeida, in the Antofagasta region, northern Chile, which belongs to the Famatinian arc. Two plutonic rock types can be distinguished: granodiorites and monzogranites. The first lithology is positioned along an occidental fringe in as much the second is located along an oriental part of the batholith. The main geochemical difference between the two lithologies is the enrichment in silica and K of the second with respect of the first one. Most of the granodiorites are metaluminous or are located between the metaluminous and peraluminous fields. The monzogranites are mostly peraluminous. The chemical composition of the plutons (mayor and trace elements and rare earth elements) allow to infer a common origin for both groups, from a mafic magma that evolved by fractional crystallization. The difference in composition between both lithologies, specially the meta or peraluminous character, can be explained by means a different degree of interaction of the original magma with the felsic crustal rocks.

Published: October 2020

Abstract. Liquid–liquid phase separation (LLPS) in organic aerosol particles can
impact several properties of atmospheric particulate matter, such as cloud
condensation nuclei (CCN) properties, optical properties, and
gas-to-particle partitioning. Yet, our understanding of LLPS in organic
aerosols is far from complete. Here, we report on the LLPS of one-component and
two-component organic particles consisting of α-pinene- and β-caryophyllene-derived ozonolysis products and commercially available
organic compounds of relevance to atmospheric organic particles. In the
experiments involving single-component organic particles, LLPS was observed
in 8 out of 11 particle types studied. LLPS almost always occurred when the
oxygen-to-carbon elemental ratio (O:C) was ≤0.44 but did not occur
when O:C was >0.44. The phase separation occurred by spinodal
decomposition as well as the nucleation and growth mechanism, and when LLPS occurred,
two liquid phases coexisted up to ∼100 % relative humidity
(RH). In the experiments involving two-component organic particles, LLPS was
observed in 23 out of 25 particles types studied. LLPS almost always
occurred when the average was O:C ≤0.67 but never occurred when the
average O:C was >0.67. The phase separation occurred by spinodal
decomposition as well as the nucleation and growth mechanism. When LLPS occurred, two
liquid phases coexisted up to ∼100 % RH. These results
provide further evidence that LLPS is likely a frequent occurrence in
organic aerosol particles in the troposphere, even in the absence of
inorganic salts.

Published: October 2020

Abstract. Drained peatlands are one of the main sources of carbon dioxide (CO2) emissions globally. Emission reduction and, more generally, ecosystem restoration can be enhanced by raising the water table using canal or drain blocks. When restoring large areas, the number of blocks becomes limited by the available resources, which raises the following question: in which exact positions should a given number of blocks be placed in order to maximize the water table rise throughout the area? There is neither a simple nor an analytic answer. The water table response is a complex phenomenon that depends on several factors, such as the topology of the canal network, site topography, peat hydraulic properties, vegetation characteristics and meteorological conditions. We developed a new method to position the canal blocks based on the combination of a hydrological model and heuristic optimization algorithms. We simulated 3 d dry downs from a water saturated initial state for different block positions using the Boussinesq equation, and the block configurations maximizing water table rise were searched for by means of genetic algorithm and simulated annealing. We applied this approach to a large drained peatland area (931 km2) in Sumatra, Indonesia. Our solution consistently outperformed traditional block locating methods, indicating that drained peatland restoration can be made more effective at the same cost by selecting the positions of the blocks using the presented scheme.
How Salty Is the Global Ocean: Weighting It All or Tasting It a Sip at a Time?
Authors: Ponte Rui , Sun Qiang , Liu Chao , Liang Xinfeng
Published: October 2020

Global ocean mean salinity S is a key indicator of the Earth's hydrological cycle and the exchanges of freshwater between the terrestrial water and ice reservoirs and the ocean. We explore two different ways of determining how salty the ocean is: (1) use in situ salinity measurements to taste the ocean a sip at a time and obtain a sample average; (2) use space gravimetry to weigh the whole ocean including sea-ice, and then separate sea-ice effects to infer changes in liquid freshwater content and thus S. Focusing on the 2005-2019 period, we assess monthly series of S derived from five different in situ gridded products, based mostly but not exclusively on Argo data, versus a series obtained from GRACE and GRACE Follow-On data and available sea ice mass estimates.

There is little consistency in S series from the two methods for all time scales examined (seasonal, interannual, long-term trend). In situ series show larger variability, particularly at the longest scales, and are somewhat incoherent with the GRACE-derived series. In addition, there are wide spread differences among all the in situ S series, which denote their considerable sensitivity to choice of data, quality control procedures, and mapping methods. Results also suggest that in situ S values are prone to systematic biases, with most series showing increases after around 2014 that are equivalent to a drop in barystatic sea level of tens of centimeters! Estimates derived from GRACE are much smaller in magnitude and consistent with contributions of freshwater to the global mean sea level budgets, and they are thus more reliable than in situ-based S estimates. The existence of GRACE-derived estimates can serve as a consistency check on in situ measurements, revealing potential unknown biases and providing a way to cross-calibrate the latter data.
Gravity Field Recovery and Observation Noise Separation from Simultaneous Laser Ranging Interferometer and K-Band Ranging System Measurements
Authors: Kvas Andreas , Behzadpour Saniya , Mayer-Guerr Torsten
Published: October 2020

The unique instrumentation of GRACE Follow-On (GRACE-FO) offers two independent inter-satellite ranging systems with concurrent observations. Next to a K-Band Ranging System (KBR), which has already been proved during the highly-successfully GRACE mission, the GRACE-FO satellites are equipped with an experimental Laser Ranging Interferometer (LRI), which features a drastically increased measurement precision compared to the KBR. Having two simultaneous ranging observations available allows for cross-calibration between the instruments and, to some degree, the separation of ranging noise from other sources such as noise in the on-board accelerometer (ACC) measurements.  

In this contribution we present a stochastic description of the two ranging observation types provided by GRACE-FO, which also takes cross-correlations between the two observables into account. We determine the unknown noise covariance functions through variance component estimation and show that this method is, to some extent, capable of separating between KBR, LRI, and ACC noise. A side effect of this stochastic modelling is that the formal errors of the spherical harmonic coefficients fit very well to empirical estimates, which is key for combination with other data types and uncertainty propagation. We further compare the gravity field solutions obtained from a combined least-squares adjustment to KBR-only and LRI-only results and discuss the differences between the time series with a focus on gravity field and calibration parameters. Even though, at the moment, global statistics only show a minor improvement when using LRI ranging measurements instead of KBR observations, some parts of the spectrum and geographic regions benefit significantly from the increased measurement accuracy of the LRI. Specifically, we see a higher signal-to-noise ratio in low spherical harmonic orders and the polar regions.
The Ongoing Central European Drought Observed with GRACE Follow-On
Authors: Boergens Eva , Güntner Andreas , Dobslaw Henryk , Dahle Christoph
Published: October 2020

In the last three years Central Europe experienced an ongoing severe drought. With the data of the GRACE Follow-On (GRACE-FO) mission we are able to quantify the water deficit of these years. Since May 2018 GRACE-FO continues the observations of GRACE (2002-2017) allowing to compare the most recent drought with earlier droughts in 2003 and 2015.

In July 2019 the water mass deficit in Central Europe amounted to -154 Gt, which has been the largest deficit in the whole GRACE and GRACE-FO time series. In November 2018 the deficit reached -138 Gt and in June 2020 -147 Gt. Comparing these deficits to the mean annual water storage variation of 162 Gt shows the severity of the ongoing drought. With such a water mass deficit, a fast recovery within one year cannot be expected. In comparison to this, the droughts of 2003 with a deficit of -55 Gt and of 2015 with a deficit of -111 Gt were less severe.

The GRACE and GRACE-FO total water storage data set also allows for analysing spatio-temporal drought patterns. In 2018 the drought was centred in in the South-West of Germany and neighbouring countries while parts of Poland were hardly affected by the drought. In 2018 the drought reached its largest extent only in late autumn. However, the exact onset of drought is not determinable due to missing data between July and October. Both in 2019 and 2020 the centre of the drought is located further East and the months with the largest deficit were July and June, respectively. Also in the later years, the drought was more evenly spread out over the whole of Central Europe.

Additionally, we compared the GRACE and GRACE-FO data to an external soil moisture index and to surface water drought indices for Lake Constance and Lake Müritz. To this end, we derive a drought index from the GRACE and GRACE-FO mass anomalies. For the whole time series, the GRACE drought index shows a high congruency to the soil moisture drought index. Overall, the surface water drought index also fits well together with the GRACE drought index. However, the comparison reveals the influence of regional effects on surface waters not observable with GRACE and GRACE-FO.
GRACE/GRACE-FO mascons and satellite laser ranging: Updates from GSFC
Authors: Loomis Bryant , Croteau Michael , Sabaka Terry , Luthcke Scott , Rachlin Kenny
Published: October 2020

We present a summary of our recent work on time-variable gravity estimates derived from GRACE/GRACE-FO and satellite laser ranging (SLR). We show the latest results of our monthly mascon solution, with special attention paid to the selection and impact of the damping parameter applied to the regularization matrices. Additionally, we present a new method of regularized mascon estimation from spherical harmonics. Provided that the full normal equations for these coefficients are available, this method allows for a mathematically equivalent mascon estimate to those determined from a single iteration solution from Level-1B observations, but at a fraction of the computational cost. For this we use the ITSG-Grace2018 solution and full normal equations to produce a new mascon solution of comparable quality to current mascon products, and we are in the process of using this rapid approach to perform a trade study of various regularization strategies. Lastly, we present low degree SLR solutions that form the basis of the C20 and C30 solutions provided in Technical Note 14, and present preliminary results of large SLR-derived mascons from 1993 – Present.
Revisiting the sampling problem of satellite gravimetry – a perspective from the Bender configuration
Authors: Yadav Anshul , Devaraju Balaji , Weigelt Matthias , Sneeuw Nico
Published: October 2020

The signal acquisition by the two different GRACE-like satellite pairs in a Bender configuration - polar and inclined, is dissimilar to each other. This difference is attributable to differing relative sampling geometry and global coverage. While the polar pair covers the entire globe, the inclined pair does not cover the higher latitudes leaving a local discontinuity around the poles in acquired signal (better known as the Polar Gap problem). Similarly, due to its north-south orientation, the polar pair can capture well the features that are predominantly oriented in the east-west direction. We simulated a Bender configuration using ESA's Earth System Model to see how the two satellite pairs contributed to the spherical harmonic coefficients. The general pattern was that the polar orbit contributed strongly to the zonal coefficients and the tesserals around it (near-zonal coefficients) while the inclined orbit contributed strongly to the other tesseral and the sectorial coefficients, which is well known. We also found out that the weak zonal and near-zonal inclined pair contributions lay inside a wedge in the spectral space, very similar to the polar gap error wedge. We want to discern how the satellites' relative geometry, particularly the polar gap issue in the inclined pair of a bender configuration, affects the solution's spectral resolution. In this study, we model the contribution coefficients of the polar and inclined pairs as a function of orbit geometries, employing the semi-analytical framework based on inclination functions. We hope that this will help in understanding the spectral resolution of the next generation gravity missions.
Design of GRACE-like Small Satellite Constellations for Improved Temporal Gravity Measurements.
Authors: Deccia Carlos M.A. , Wiese David N. , Loomis Bryant D. , Nerem R. Steven
Published: October 2020

We have been investigating the science performance for different gravity mission constellation architectures using smallsats. Small satellite systems are increasingly being used in scientific missions, due to their increase in affordability and improvement in performance over the past years. A small satellite constellation of GRACE-like pairs or other inter satellite ranging configurations would allow for improved spatial and temporal resolution as well as allowing for a high inherent system redundancy and a lower overall cost. Additionally, such a mission architecture would be more robust to failure since a constellation is insensitive to single point failures and individual satellites can be replaced at a lower cost.
The design of such a mission architecture is not straightforward due to the vast search space that needs to be considered. In this work we make use of a multi-objective evolutionary algorithm that is population-based and metaheuristic based on Darwinian theory in order to identify future GRACE-like constellations that are optimized to retrieve sub-monthly time-varying gravity field events.
Assessing Detectability of Global Flood Occurrences using Daily and Monthly GRACE/GRACE-FO
Authors: Rateb Ashraf , Sun Alexander , Scanlon Bridget , Save Himanshu
Published: October 2020

 

Floods pose a threat to the lives of millions of people globally each year, with economic losses exceeding those of any other natural hazard. Improving flood forecasting with longer lead times can support enhanced risk management strategies and reduce associated socioeconomic losses. The objective of this study was to assess the detectability of floods using newly developed GRACE daily and regular monthly total water storage data. 

We compared total water storage (TWS) maxima from GRACE and GRACE-FO with flood occurrences from 2002 to 2020. GRACE daily TWS maxima were based on three daily GRACE solutions (UTCSR-RSWM, GFZ-RBF, and ITSG-2018) derived using statistical learning and geophysical models for the GRACE period (2002-2017). Monthly GRACE and GRACE-FO data were based on mascons solutions from UT-CSR and NASA-JPL for 2002-2020. A flood susceptibility index was developed based on the climate signal portion in the TWSA and compared with other flood indices (e.g., standardized precipitation index and streamflow). We evaluated the spatiotemporal coincidence rate of change of the 90th percentile of the daily and monthly precipitation based on the GPM-Imerg and GPCP rainfall data and the corresponding 90th percentile of the daily and monthly TWSA. The coincidence rate between GRACE TWSA maxima and precipitation were also compared relative to actual flood data (~3000 events) from the Dartmouth flood Observatory (DFO) catalog. 

Preliminary results using precipitation data from GPCP reveal that monthly GRACE/GRACE-FO data have a high predication rate for the monthly maxima precipitation > 90th percentile with a lead time of ~ two months across the tropical rain belt. Assessment against the real flood events shows that the three daily GRACE data perform well for flood events resulting from heavy and monsoonal rain and slightly differ for the events triggered by snowmelt and storm surges. The duration of flood events from GRACE data is generally shorter than the periods reported by DFO. An empirical relationship was derived between floods' duration based on the cause and the expected precursor coincidence rate from daily GRACE data. Further analysis is necessary to evaluate the GRACE precursor rate using different lead times and tolerance windows, quantify the change in rate relative to climate, topography, and soil types, and interpret the different performance GRACE products. This preliminary analysis suggests the high potential for GRACE/GRACE-FO data to extend flood forecast lead times and potentially improve the mitigation strategies
The Prominent Role of GRACE in the Series of IMBIE Studies: Future Plans and Prominent Issues
Authors: Ivins Erik , Shepherd Andrew
Published: October 2020

The Ice Mass Balance Intercomparison Exercize  (IMBIE) was initiated in 2011 with the intent of better reconciling the various reports  on the Greenland ice sheet (GrIS)  and Antarctic ice sheet (AIS) mass balance during the 2000’s. The focused study was funded and promoted by both ESA and NASA to better understand the origins of  contradictory results using space observations for a 20 year-long period: 1990-2010. Here we review some of the main results of phase I and II of IMBIE and the strength of the GRACE mission results.  For 20-year long trends (2002-2021) trends are influenced by glacial isostatic adjustment (GIA) in Greenland, but with more profound consequence for Antarctica. IMBIE-I determined a mass balance trend for 1992-2011: -142 ± 49 and -71 ± 83 Gt/yr, for GrIS and AIS, respectively.  IMBIE-II was open to a wider sampling of international  investigative teams and the results for GrIS over 1992-2018 changed to -150 ± 13 Gt/yr. Most notably the 1-sigma formal errors reported in IMBIE-II were 25% of those reported in the earlier IMBIE-I study for GrIS. For Antarctica the most notable contrast in results was the total value of the trend over 1992-2017 (IMBIE-II) in contrast 1992-2011 (IMBIE-I) (-109 ± 56 vs -71 ± 83 Gt/yr, respectively). The loss estimate for AIS rose by 67% and the error also reduced by about 33%. Glacial isostatic adjustment (GIA) estimates for Antarctica cluster around + 54 Gt/yr (meaning their correction adds to the negativity of the mass balance result for GRACE and GRACE-FO).  The East Antarctica Ice Sheet (EAIS) has trend errors for the estimate 1992-2017 (IMBIE-II) that continue to dwarf the uncertainty: +5 ± 46 Gt/yr. Beneath EAIS, GIA is also most uncertain and models have the greatest spread. We discuss the general plan for IMBIE-III that is currently forming.
Comparing and evaluating GRACE and GRACE-FO mascon data in the study of polar motion excitation
Authors: Śliwińska Justyna , Wińska Małgorzata , Nastula Jolanta
Published: October 2020

The Gravity Recovery and Climate Experiment (GRACE) mission has provided global observations of temporal variations in mass redistribution at the surface and within the Earth for the period 2002–2017. Such measurements are commonly exploited to interpret polar motion changes due to variations in the Earth’s surficial fluids, especially in the continental hydrosphere. Such impacts are usually examined by computing the so-called hydrological polar motion excitation (Hydrological Angular Momentum, HAM). The great success of the GRACE mission and the scientific robustness of its data contributed to the launch of its successor, GRACE Follow-On (GRACE-FO), which begun in May 2018 and continues to the present.

This study compares the estimates of HAM computed from GRACE and GRACE-FO mascon data provided by three data centers: Jet Propulsion Laboratory (JPL), Center for Space Research (CSR), and Goddard Space Flight Center (GSFC). The analysis of HAM is performed for different spectral bands. A validation of different HAM estimates is conducted here using precise geodetic measurements of the pole coordinates and geophysical models (so-called geodetic residuals or GAO).

Comparison of HAM computed from different mascon data sources indicates high consistency between the solutions provided by JPL and CSR, and low consistency between the GSFC solution and other data. The reason for this may be that the strategy used for GSFC mascons computation is different than methodology exploited by CSR and JPL teams. This study also indicates that HAM computed using CSR and JPL solutions are characterized by the highest consistency with GAO in all considered spectral bands.
Some Analytical Results for Models of the Bid-Ask Spread
Authors: Parameswaran Sunil K. , Basu Sankarshan
Published: October 2020

The focus of this paper is on order processing models of the bid-ask spread, also termed as fixed-cost models. While other theories have been advanced to explain spreads, such as inventory holding costs and adverse selection, research indicates that the fixed cost component constitutes the bulk of the observed spread. This paper starts with the Roll model and the subsequent extension of Choi, Salandro and Shastri. It takes cognizance of the implications of such models for the observed stock prices and the mid-points of bid-ask quotes, to set up tests using the Generalized Method of Moments (GMM) technique. The paper develops an analytical variance-covariance matrix for the fixed cost model with instantaneous adjustment of prices to new information.

Innovative Wearable Sensors Based on Hybrid Materials for Real-Time Breath Monitoring
Authors: Roudjane Mourad , Messaddeq Younès
Published: October 2020

This chapter will present the importance of innovative hybrid materials for the development of a new generation of wearable sensors and the high impact on improving patient’s health care. Suitable conductive nanoparticles when embedded into a polymeric or glass host matrix enable the fabrication of flexible sensor capable to perform automatic monitoring of human vital signs. Breath is a key vital sign, and its continuous monitoring is very important including the detection of sleep apnea. Many research groups work to develop wearable devices capable to monitor continuously breathing activity in different conditions. The tendency of integrating wearable sensors into garment is becoming more popular. The main reason is because textile is surrounding us 7 days a week and 24 h a day, and it is easy to use by the wearer without interrupting their daily activities. Technologies based on contact/noncontact and textile sensors for breath detection are addressed in this chapter. New technology based on multi-material fiber antenna opens the door to future methods of noninvasive and flexible sensor network for real-time breath monitoring. This technology will be presented in all its aspects.
Dare to be Disruptive! The Social Stigma toward Creativity in Higher Education and a Proposed Antidote
Authors: Lohiser Amanda , J. Puccio Gerard
Published: October 2020

Despite the fact that creativity has been named one of the top-10 skills necessary for success in the twenty-first century, the current educational system in the developed world stifles creativity through its focus on convergent thinking and standardized testing. We propose that a stigma toward creativity exists among educators, which prevents successful implementation of creative teaching and fostering creativity within the classroom. The proposed root cause of the stigma toward creativity in education – that creativity is perceived as disruptive – is examined through the lens of the Adaptor-Innovator theory of creativity and the implicit and explicit theories of creativity, as well as the psychological factors inherent to the social construction of stigma. Seminal and current research in the fields of creativity studies and communication studies offer insight into this phenomenon. The chapter concludes by proposing an antidote to address and fight this stigma as seen through the lens of Fishbein and Ajzen’s Theory of Reasoned Action.
Adaptive Mechanisms of Root System of Rice for Withstanding Osmotic Stress
Authors: Hannan Afsana , Najmol Hoque Md. , Hassan Lutful , Hasan Khan Robin Arif
Published: October 2020

Being one of the major cereal crops, rice has a great effect on food security of the world population. But worldwide rice production faces severe threat due to a combination of factors like uncontrolled human rise, limited agricultural land and increasing environmental stresses. Coping with this situation is an urgent call for meeting the challenge. For overwhelming rice production by battling with this condition, scientists and researchers try their best to develop such rice varieties which can adapt to adverse climatic conditions. But, the majority of the research efforts are given on above ground parts of rice to make it stress tolerant. Root, one of the major parts of plant, remains unnoticed although it has immense possibility of adaptation under stress conditions. Fruitful and efficient utilization of limited resources are possible through healthier and competent root systems. Selection and breeding of rice genotypes with extensive root systems may contribute to more efficient use of soil nutrient resources and this ultimately influences the yield stability of rice.
Life Is Not on the Edge of Chaos but in a Half-Chaos of Not Fully Random Systems. Definition and Simulations of the Half-Chaos in Complex Networks
Authors: Gecow Andrzej
Published: October 2020

The research concerns the dynamics of complex autonomous Kauffman networks. The article defines and shows using simulation experiments half-chaotic networks, which exhibit features much more similar to typically modeled systems like a living, technological or social than fully random Kauffman networks. This represents a large change in the widely held view taken of the dynamics of complex systems. Current theory predicts that random autonomous systems can be either ordered or chaotic with fast phase transition between them. The theory uses shift of finite, discrete networks to infinite and continuous space. This move loses important features like e.g. attractor length, making description too simplified. Modeled adapted systems are not fully random, they are usually stable, but the estimated parameters are usually “chaotic”, they place the fully random networks in the chaotic regime, far from the narrow phase transition. I show that among the not fully random systems with “chaotic parameters”, a large third state called half-chaos exists. Half-chaotic system simultaneously exhibits small (ordered) and large (chaotic) reactions for small disturbances in similar share. The discovery of half-chaos frees modeling of adapted systems from sharp restrictions; it allows to use “chaotic parameters” and get a nearly stable system more similar to modeled one. It gives a base for identity criterion of an evolving object, simplifies the definition of basic Darwinian mechanism and changes “life on the edge of chaos” to “life evolves in the half-chaos of not fully random systems”.
Results From 16 Years of Quality Surveillance of Urine Albumin to Creatinine Ratio Testing for a National Indigenous Point-of-Care Testing Program
Authors: Regnier Tamika , Shephard Mark , Shephard Anne , Graham Peter , DeLeon Rizzi , Shepherd Samantha
Published: October 2020

Context.—

The burden of chronic kidney disease in Indigenous Australians is 7.3 times higher than that of non–Indigenous Australians. If chronic kidney disease is detected early and managed, deterioration in kidney function can be reduced. Urine albumin to creatinine ratio is a key marker of early renal damage.

Objective.—

To report on 16 years of analytic quality of urine albumin to creatinine ratio testing on Siemens DCA devices enrolled in the national Quality Assurance for Aboriginal and Torres Strait Islander Medical Services point-of-care testing program.

Design.—

Quality Assurance for Aboriginal and Torres Strait Islander Medical Services participants are required to test 2 quality assurance samples each month across two 6-monthly testing cycles per year. Participants also test 2 quality control samples monthly.

Results.—

The percentage of urine albumin, creatinine, and albumin to creatinine ratio results for quality assurance point-of-care testing that were within assigned allowable limits of performance averaged 96.9%, 95.9%, and 97.5%, respectively. The percentage acceptable quality control results for urine albumin and creatinine averaged 93.5% and 86.8%. The median imprecision for urine albumin, creatinine, and albumin to creatinine ratio quality assurance testing averaged 5.5%, 4.1%, and 3.3%, respectively, and the median within-site imprecision for quality control testing averaged 5.4%, 4.3%, and 5.7%, respectively, for the low sample and 4.0%, 4.1%, and 4.5%, respectively, for the high sample.

Conclusions.—

For 16 years the DCA system has proven to be reliable and robust and operators at Aboriginal medical services have demonstrated they are able to conduct point-of-care testing for urine albumin to creatinine ratio that consistently meets analytic performance standards.

His fundamental contribution to the geographical field was, at a time of generational transition and methodological reflection in Spanish Geography, the introduction of the new geographical currents that were happening beyond our borders, such as the Geography of Perception and Quantitative Geography, issues in those who pioneered in Spain.  Epistemological issues also had a great weight, being a recurring theme throughout his work. As a teacher, he also reflected on teaching in Geography, not only in university settings, where he was practicing, but also in secondary education.
Etiopía: recorrido por algunos paisajes naturales y culturales
Authors: Pardo Abad Carlos
Published: October 2020

Etiopía es un país fascinante situado en la zona conocida como “Cuerno de África”. Con una superficie superior a 1,1 millones de km2 y una población no del todo conocida por los problemas de recuento censal propios de los países subdesarrollados, pero que podría rondar los 105 millones de habitantes, es un país federal que engloba culturas y lenguas diferentes, paisajes deslumbrantes y monumentos poco reconocibles inicialmente como del continente africano. La visita al país, que tuve la oportunidad de realizar en abril-mayo de 2019, me aportó una de las experiencias más intensas en mi dilatada carrera como viajero.

Um olhar sobre o impacto da experiência teatral no exercício da alteridade e no processo de socialização de crianças em contextos educacionais
Authors: Mendonça Celida Salume , Bezelga Isabel Maria Gonçalves
Published: October 2020

As reflexões que aqui seguem dialogam com a investigação de pós-doutoramento realizada no Centro de História da Arte e Investigação Artística da Universidade de Évora (CHAIA), que buscou aprofundar a ideia de que o uso intencional de diferentes materialidades nos percursos de criação teatral mobiliza os envolvidos, ajudando-os a reagir às experiências instauradas e facilitando a interação entre os participantes. O artigo divide-se em duas partes centrais: a primeira contém a explanação de um recorte da experiência de ensino vivenciada com os alunos do curso Licenciatura Educação Básica da Universidade de Évora, na disciplina Oficina de Integração das Expressões; e a segunda é dedicada a questões suscitadas pelo fazer teatral desenvolvido com crianças no contexto de educação básica 1º ciclo na Escola da Cruz da Picada. As múltiplas possibilidades oferecidas pelas materialidades em jogo nos dois contextos, abrem perspectivas aos participantes pensando e fazendo, para serem inventivos e sensíveis. Como o processo de aprendizagem passa pelo seu corpo e o corpo do outro, permite vivenciar novas formas de comunidade, concebendo de modo mais amplo a alteridade. Os resultados obtidos voltam-se para o aperfeiçoamento da formação de docentes e pesquisadores da pedagogia do teatro no contexto brasileiro e português construindo novas colaborações.
Práticas de cuidado e cultivo da atenção com crianças
Authors: Caliman Luciana Vieira , Kastrup Virgínia , César Janaína Mariano
Published: October 2020

Este estudo analisa uma experiência realizada no Brasil, na qual crianças diagnosticadas com Transtorno de Déficit de Atenção e Hiperatividade (TDAH) e outros problemas relacionais, usuárias de um Centro de Atenção Psicossocial Infantojuvenil (CAPSi), participam de uma oficina de leitura de literatura. A proposta da Oficina da Palavra é oferecer uma alternativa ao uso da medicação como modo central de tratamento, por meio de um dispositivo grupal e participativo de leitura e também de cuidado. A oficina foi realizada como uma pesquisa-intervenção baseada no método da cartografia. Através da proposição de um dispositivo grupal de cuidado, dá-se relevo à dimensão conjunta da atenção e a importância de construir ecossistemas atencionais nos quais a atenção a si e aos outros é cultivada. A partir de uma perspectiva ecológica que ultrapassa o viés individualista e naturalista da atenção, o cuidado dos problemas atencionais surge como um trabalho de cultivo de correspondência e atenção conjunta concentrada e aberta, envolvendo a construção de ecossistemas atencionais favoráveis.
Haptic Exploration of Urban Belgrade—Uniting Female Gazes through the Project Wa(o)ndering Women
Authors: Maksimovic Maja , Joksimović Jelena , Utvić Mirjana
Published: October 2020

The study attempts to discover elements of learning by practicing the right to the city through the embodiment and re-articulation of the identity of the ﬂâneuse. In this urban investigation, we will explore perspectives that emerge from the city, how they are connected to specific city sites, and how they form our becomings, having in mind the gendered division of urban life. In order to do so, we will engage in reflexive wandering and performing in the city. Learning that unfolds with this action is a bodily and sensorial process of reading the layers of public spaces in the city. As wandering implies a turn off the main road, the learning process is marked by unpredictability and meandering. It does not follow a familiar path that leads to specific learning outcomes, but involves a journey through unknown and unowned places. We aim to describe learning that evolves by wandering around the side roads of Belgrade by mapping the experiences of the three authors. The research also involves reminiscences of the wandering of women in Belgrade that we want to re-enact and document.
A promoção da acessibilidade linguística ao docente surdo na UFG/Regional Catalão
Authors: Souza Kássia Mariano de , De Paula Maria Helena
Published: October 2020

O objetivo deste artigo é analisar como a Universidade se posiciona frente aos desafios legais para a implementação da acessibilidade linguística aos docentes surdos, principalmente no que tange à contratação do profissional intérprete como meio de inclusão do professor no contexto acadêmico. Assim, buscamos analisar as políticas públicas voltadas à acessibilidade deste profissional, tendo em vista que é recorrente sua inserção nas salas de aula e, sobretudo, nas universidades. O objeto de pesquisa desse trabalho é discutir sobre a promoção da acessibilidade linguística ao docente surdo na UFG/Regional Catalão, onde há uma atuação frequente de educadores com surdez. A fundamentação teórica do estudo se valeu das obras de autores que atuam na área da inclusão e acessibilidade da pessoa surda como Schubert (2012) e Quadros (2004; 2005).  Realizamos ainda uma pesquisa documental sobre as medidas tomadas para tornar o ambiente acadêmico mais acessível a esses profissionais na instituição. Além disso, analisamos a legislação que abrange assuntos concernentes à acessibilidade que legalmente deve ser oferecida às pessoas surdas como suporte para correlacionar às informações obtidas. A pesquisa revelou que a Universidade ainda não está preparada para incluir o profissional surdo como parte constituinte da instituição.
Social and Psychological Support for Personnel in Organisations: Work-Life Balance Programmes

Objective: The study aimed to explore the work-life balance concept, assessing the level and the peculiarities of work-life balance.
Background: The paper covers the psychological reconstruction of the concept of "the work-life balance" in terms of its implicit understanding and differentiated diagnosis.
Method: The main research methods are: theoretical – the study of literature on the research problem; empirical – a study on the methodology for assessing psychological well-being, as well as methods of descriptive and analytical statistics.
Results: It has been designed an inventory based on 16 statements divided into the work-life balance components by means of the factor analysis. Satisfaction with work and family roles have been found to have additive effects on happiness, life satisfaction, and perceived quality of life. The basic strategies in social and psychological programs in organisations have been analysed as focus strategies, "resource/refusal" strategies, adaptive strategies. Adaptive strategies are the ones helping to adapt to problems arising at work or/and at home.
Conclusion: Empirical findings suggest that involvement in multiple roles can improve psychological and mental health by buffering negative effects such as reduced. The use of individual adaptive strategies with the resource increase strategy perfectly contributes to the work-life balance achievement.
