Published: August 2020

The purpose of the present study is to evaluate the adoption of Mediterranean diet in adolescents with intellectual disabilities. The sample of the study consisted of 24 adolescents (8 boys and 16 girls) with intellectual disabilities who were studying at a secondary education school, with an average age of 17.63+2.018 years. For data collection, the Mediterranean Diet Quality Index for Children and Adolescents (KIDMED) by Serra-Majem et al. (2004) was used. KIDMED is supported by specific principles sustaining traditional healthy Mediterranean dietary patterns. KIDMED is based on a 16-item food consumption log questionnaire that can be answered either self-administered or in interview. As for the pupils with intellectual disabilities, the answers were recorded in an individual interview. For the statistical analysis the Statistical Package for Social Sciences ver. 23.0 for windows was used. Data processing showed that over the 1/3 of adolescents with intellectual disabilities (37.5%) has a very low diet quality, while the proportion of adolescents following an optimal Mediterranean diet was zero. In addition, the diet of the adolescents with intellectual disabilities in a very large proportion (62.5%) needs improvement for the adaptation of the consumption / intake to Mediterranean patterns. The results show that adolescents with intellectual disabilities do not follow the Mediterranean diet. Therefore, priority should be given to the application and implementation of health educational programs on diet in general, and more specifically on the benefits of Mediterranean diet to adolescents with intellectual disabilities, in order to adopt the Mediterranean diet patterns aiming on the beneficial effects, both directly and long-term in their adult life.

El El test de disponibilidad de derechos frente al principio de irrenunciabilidad en el nuevo proceso laboral
Authors: Gerónimo de la Cruz Jaime
Published: August 2020

La incorporación de la oralización en el proceso laboral ha implicado una dinámica diferente a la que antes se tenía; pero este no ha sido el único cambio en la reforma laboral. Por lo tanto, nuevas formas especiales de conclusión del proceso se han incorporado a este nuevo sistema procesal. Así, el empleador o el empleado pueden ejercer su derecho de acción para recurrir a otros mecanismos que resuelvan el disenso en la relación laboral. Este nuevo método legislativo ha traído consigo que se establezcan dos posiciones antagónicas: por un lado, están quienes sostienen la viabilidad de aplicar el test de disponibilidad basada en la autonomía privada y la iniciativa de parte en el proceso; y, por otro,  aquellos que argumentan, bajo el principio de irrenunciabilidad, el rol protector que debe tener el juez frente a estos procesos.

Published: August 2020

Agricultural land has decreased the impact on farmers in meeting their needs. The transition to agriculture complicates industry in its effort to meet the needs of farmers. Another issue, climate change will disrupt plant crops that will result in inefficient farming. Farming inefficiencies are a reason for farmers to diversify. This study was based on a micro data survey data of agricultural enterprise household income in the Regencies / Cities of West Java on a household level. Limits of household income diversification of farming is when the household has to venture outside the agricultural sector or one of the cores and the sources of income comes from salaries / wages of laborers / employees outside the agricultural sector. The results showed that with the increasing age of the household head the diversity decreases, the higher the education of the head of household the more it encourages the diversification of income, the more the additional land area increases diversification, the easier access to credit for adding revenue diversification, increasing the income of farmers that tend not to diversify, the more houses and stairs in school which support farmers to diversify, the more productive the household income lowers with diversification.

Interest Rate Pass-Through: Empirical Study Towards Monetary Policy Transmission Effectiveness in Indonesia
Authors: Hasanah Heni
Published: August 2020

This research aims to measure the effectiveness of monetary policy transmission, especially through the interest rate channel. The analysis was conducted on the first stage of its transmission, namely Interest Rate Pass-through (IRPT). IRPT refers to condition in which retail interest rate (both deposit and lending rate) responds to changes in policy rate of central bank. IRPT was measured using Error Correction Model (ECM) for time series data in the period of January 2010 - December 2015. The results of this study indicated that degree of long term and short term IRPT is incomplete for deposit and lending rate. In addition, IRPT for deposit rate is higher than lending rate, but the adjustment process of lending rate faster than deposit rate. Finally, model that include other variables (macroeconomic and internal banking indicator) generate long term IRPT which is smaller than the standard model. This results implies that the Central Bank, the FSA, and government needs to pay attention to the stability of the other variables that may interfere or reduce the effectiveness of monetary policy through the interest channel.

Analysis of Uneven Regional Development in North-East, Middle–Southeast, and West-South Regions of Aceh Province
Authors: Wahyuningsih Yayuk Eko , Putra Irfan Syah , Meliana Eni
Published: August 2020

Aceh is a province of Indonesia that currently consists of 23 districts/municipalities that are generally divided into three (3) regions, namely, the Northeast (11 districts/municipalities), the Middle-southeast (4 districts) and the Southwest (8 districts/municipalities) regions. These regions have different natural, human, social, political, and cultural resources. These differences have caused uneven economic development, which has further caused developmental disparity among the regions.

This study aims to assess the extent of developmental disparity among regions and to analyze the impact of Gross Regional Domestic Product per capita on regional developmental disparity in the three (3) regions of Aceh province in the period of 2000-2014. The data used in this research are secondary data that were obtained from the Central Statistics Agency (BPS), and the Regional Development Planning Board (Badan Perencanaan Daerah/Bappeda) of Aceh Province. To identify the level of inequality, the researcher utilizes Williamson Index;whereas to determine theimpact of Regional GDP per capita on the inequality of regional development, the researcher utilizes a semi logarithmic linear regression model that includes a discussion on the correlationcoefficient (R), determination coefficient (R Square), and t test using SPSS.

Based on estimation results, the researcher discovers that, for the North-East region,the value of correlation coefficient (R) is 0.8032, the value of determination coefficient is 64.52%, and the equation for Y isY = -1.8942 + 0,1263X;for the Middle-Southeast region, the value ofcorrelation coefficientis0.6760, the value of determination coefficient is 45.70%, and the equation for Y is Y = 0.6441 + 0,0400X, and;for the Southwest region,the value ofcorrelation coefficientis 0.4045, the value of determination coefficient is 16.36%, and the equation for Y is Y = -0.4703 + 0,0318X. As for the t test, the researcher discovers that for North-East region the per capita regional GDP wastcount> ttable(4.671> 1.7823);for the Middle-Southeast regional tcount<ttable(-3.178<1.7823), and; for the Southwest region tcount<ttable (1.532 <1.7823). These per capita regional GDP values mean that only in the Northeast region does the variable of per capita regional GDP have a real impact on the variables of regional developmental disparity. This is consistent with the fact that the Northeast region is much more advanced and developed than the other two regions.

Spillover Effect of Global Financial Cycle To Asset Markets in Asean-5 Countries: A Structural VAR Approach
Authors: Andaiyani Sri , Falianty Telisa Aulia
Published: August 2020

An upsurge and volatility of capital flows to Emerging Asian Economies indicated that there is the potential effect of global financial cycle to emerging market. It provides an overview of investor risk aversion in short term investment after financial crisis 2008. Global financial cycle could have a significant impact to asset prices, including equity prices and property prices. Rey (2015) has triggered an interesting discussion about global financial cycle. She found that there was a global financial cycle in capital flows, asset prices and credit growth. This cycle was co‐moves with the VIX, a measure of uncertainty and risk aversion of the markets. Therefore, this study attempts to analyze empirically global financial cycle shocks, measured by the VIX, on equity prices and property prices in ASEAN-5, namely Indonesia, Malaysia, Singapore, Thailand and Philippines. We estimate quarterly frequency data from Q1 1990 to Q2 2016 with Structural Vector Autoregressive (SVAR) approach. The result of this study showed that global financial cycle has a negative significant impact on the ASEAN-5 asset markets, in spite of the response of shock differs by country and size. This result is consistent with ASEAN-5 as small open economies that remain vulnerable to the global factor. This study contributes to the literature in several ways. First, we identify not only cyclical expansions or contraction in asset markets but also the impact of global financial cycle to asset markets in ASEAN-5 countries. Second, we investigate whether there are heterogeneous responses of ASEAN-5 countries to global financial cycle shocks. Third, we also identify the pattern of cycle in ASEAN-5 countries.

Manufacturing industry is the industry that the largest contribution to GDP growth until 2017. Although still the largest source of the increase in GDP, the contribution of manufacturing to GDP continued to decline since 2015. However, this does not cause the stock price decline of manufacturing. Based on this phenomenon, this study aims to examine the internal factors are thought to be able to increase the value of the company. The population in this study are all manufacturing companies listed in Indonesia Stock Exchange in 2013-2017 as many as 144 companies with a total sample of 76 companies that obtained by purposive sampling. Then, samples were analyzed using Structural Equation Modeling results show that IC and capital structure does not directly affect the value of the company. But IC and capital structure directly affects financial performance. Thus, the financial performance is able to mediate the effects of IC and capital structure to the company's value. The better the financial performance of a company, the better is also the company's value in the eyes of investors.

ANALYSIS OF INFRASTRUCTURE EFFECT ON INDONESIA'S ECONOMIC GROWTH YEAR 2007 - 2014
Authors: Irawan Rismanto , Iskandar Deden Dinar
Published: August 2020

A production process requires inputs to be used to produce output. The input according to Solow is the capital and labor described in the Cobb – Douglas function. Infrastructure can be said as capital in an effort to increase productivity, since labor requires supporting facilities that can increase their productivity. Therefore infrastructure is seen as having an important role in driving economic growth, so that adequate infrastructure is expected to have a positive impact on economic growth. This study aims to analyze the influence of the availability of infrastructure that is divided into economic infrastructure, social infrastructure and institutional infrastructure, on the economy in Indonesia which is described by the GDP. This study uses secondary data in 33 provinces in Indonesia in 2007-2014. This study uses panel data regression using the fixed effect model and correction of Heteroscedasticity and Autocorrelation Consistent (HAC). Based on the results of econometric regression, it is known that the variables of road, electricity, education, health and capital expenditure have a positive and significant effect. While the employee expenditure variable has a positive but not significant relationship. In addition, it is known that telephone variables have a negative and insignificant relationship. The results of this study also show that electricity infrastructure has the biggest influence on economic growth..
Customer Loyalty of Islamic Banks
Authors: Adi Pramono Hari
Published: August 2020

The highly rapid growth of sharia commercial banks have required them to compete in obtaining and retaining customers. Therefore, it is important to look carefully at the position of their brands within the industry. Among the measures to see how strong the position of a brand in the market is the level of customers’ brand loyalty. There are five levels of brand loyalty, each of which indicates particular marketing challenge to be addressed. Those levels - from least loyal to most loyal - include switcher, habitual buyer, satisfied buyer, liking the brand, and committed buyer. Using questionnaire to collect primary data from 100 respondents, the results indicate that the highest brand loyalty to Islamic banks has been at the level of satisfied buyer and liking the brand, indicating that consumer loyalty to the Islamic banks has not been perfect. Loyalty needs to be improved towards the committed buyer.

OBSTACLES AND STRATEGY OF MUNICIPAL ISLAMIC BONDS ISSUANCE AS AN ALTERNATIVE OF MUNICIPAL FUNDING
Authors: Harimurti Asa Jasmine , Zaky Achmad
Published: August 2020

The objective of this thesis is to identify obstacles and strategies for municipal Islamic bond issuance as an alternative in regional financing using the Analytical Networking Process (ANP). The analysis found that the most dominant obstacle in the aforementioned issue is the local government aspect. In the aspect of the central government, the obstacle is the unavailability of studies concerning the instrument of municipal Islamic bonds. In the aspect of the local government, the obstacle is the low understanding of the government about the means of municipal Islamic bonds. In the aspect of the regional house of representative, the obstacle is the behaviour of representatives, in which they complicate bureaucracy in the issuance of municipal Islamic bonds. The most dominant solution for the obstacles and strategy in the issuance of municipal Islamic bonds is a fundamental solution. The dominant strategy for a fundamental solution is the socialization of education about municipal Islamic bonds and a promotion pattern in collaboration with Indonesia’s financial service authority.

The delimitation of Giffenity for the Wold-Juréen (1953) utility function using relative prices: a note
Authors: Sproule Robert
Published: August 2020

In the study of Giffen behavior or “Giffenity”, there remains a paradox. On the one hand, the Wold-Juréen (1953) utility function has been touted as the progenitor of a multi-decade search for those two-good, particular utility functions, which exhibit Giffenity. On the other hand, there is no evidence that the Wold-Juréen (1953) utility function has ever been fully evaluated for Giffenity, with perhaps one minor exception, Weber (, 1997). But there, Weber showed that the Giffenity of Good 1 depends upon the relative magnitude of income vis-à-vis the price of Good 2. Weber’s precondition is so vague that it lacks broad appeal. This paper offers a new and a clear cut precondition for Giffen behavior under the Wold-Juréen (1953) utility function. That is, we show that if the price of Good 1 is greater than or equal to the price of Good 2, then Good 1 is a Giffen good.

Published: August 2020

Abstract. Traditional methods of fieldwork delivery can present
learners with a range of physical, cognitive and social challenges which may
subsequently hinder their ability to engage effectively with learning. We
developed a residential geoscience field course designed to be physically
accessible to, and socially inclusive of, a diverse range of learners
including those with limited physical mobility and neurodiverse conditions.
This paper presents the logistical and pedagogical challenges involved in
delivering such a field course. In terms of pedagogic design scheduling,
pace and timing, and the ability to access content in multiple ways were
critical to ensuring that all students were included in the learning. The
most effective mitigations were the simplest and benefitted the whole group.
Practical interventions found to support access and inclusion for the
benefit of all participants included using an audio tour-guide system to
communicate with students at field locations, using a four-wheel drive
vehicle to improve access to specific locations, providing alternative
exercises such as prepared photomicrographs and rock specimens, providing
electronic tablets with suitable apps, and selecting accommodation with
accessible common-room spaces, and a dedicated quiet room.
Three-dimensional radiative transfer effects on airborne and ground-based trace gas remote sensing
Authors: Schwaerzel Marc , Emde Claudia , Brunner Dominik , Morales Randulph , Wagner Thomas , Berne Alexis , Buchmann Brigitte , Kuhlmann Gerrit
Published: August 2020

Abstract. Air mass factors (AMFs) are used in passive trace gas remote sensing for converting slant column densities (SCDs) to vertical column densities (VCDs). AMFs are traditionally computed with 1D radiative transfer models assuming horizontally homogeneous conditions. However, when observations are made with high spatial resolution in a heterogeneous atmosphere or above a heterogeneous surface, 3D effects may not be negligible. To study the importance of 3D effects on AMFs for different types of trace gas remote sensing, we implemented 1D-layer and 3D-box AMFs into the Monte carlo code for the phYSically correct Tracing of photons In Cloudy atmospheres (MYSTIC), a solver of the libRadtran radiative transfer model (RTM).
The 3D-box AMF implementation is fully consistent with 1D-layer AMFs under horizontally homogeneous conditions and agrees very well (<5 % relative error) with 1D-layer AMFs computed by other RTMs for a wide range of scenarios.
The 3D-box AMFs make it possible to visualize the 3D spatial distribution of the sensitivity of a trace gas observation, which we demonstrate with two examples. First, we computed 3D-box AMFs for ground-based multi-axis spectrometer (MAX-DOAS) observations for different viewing geometry and aerosol scenarios. The results illustrate how the sensitivity reduces with distance from the instrument and that a non-negligible part of the signal originates from outside the line of sight. Such information is invaluable for interpreting MAX-DOAS observations in heterogeneous environments such as urban areas.
Second, 3D-box AMFs were used to generate synthetic nitrogen dioxide (NO2) SCDs for an airborne imaging spectrometer observing the NO2 plume emitted from a tall stack. The plume was imaged under different solar zenith angles and solar azimuth angles. To demonstrate the limitations of classical 1D-layer AMFs, VCDs were then computed assuming horizontal homogeneity. As a result, the imaged NO2 plume was shifted in space, which led to a strong underestimation of the total VCDs in the plume maximum and an underestimation of the integrated line densities that can be used for estimating emissions from NO2 images.
The two examples demonstrate the importance of 3D effects for several types of ground-based and airborne remote sensing when the atmosphere cannot be assumed to be horizontally homogeneous, which is typically the case in the vicinity of emission sources or in cities.

Published: August 2020

Abstract. Solar-induced fluorescence (SIF) data from satellites are increasingly
used as a proxy for photosynthetic activity by vegetation and as a
constraint on gross primary production. Here we report on improvements
in the algorithm to retrieve mid-morning (09:30 LT) SIF estimates on
the global scale from the GOME-2 sensor on the MetOp-A satellite (GOME-2A)
for the period 2007–2019. Our new SIFTER (Sun-Induced Fluorescence of
Terrestrial Ecosystems Retrieval) v2 algorithm improves over a
previous version by using a narrower spectral window that avoids
strong oxygen absorption and being less sensitive to water vapour
absorption, by constructing stable reference spectra from a 6-year
period (2007–2012) of atmospheric spectra over the Sahara and by
applying a latitude-dependent zero-level adjustment that accounts for
biases in the data product. We generated stable, good-quality SIF
retrievals between January 2007 and June 2013, when GOME-2A
degradation in the near infrared was still limited. After the
narrowing of the GOME-2A swath in July 2013, we characterised the
throughput degradation of the level-1 data in order to derive
reflectance corrections and apply these for the SIF retrievals between
July 2013 and December 2018. SIFTER v2 data compare well with the
independent NASA v2.8 data product. Especially in the evergreen
tropics, SIFTER v2 no longer shows the underestimates against other
satellite products that were seen in SIFTER v1. The new data product
includes uncertainty estimates for individual observations and is
best used for mostly clear-sky scenes and when spectral residuals
remain below a certain spectral autocorrelation threshold. Our results
support the use of SIFTER v2 data being used as an independent
constraint on photosynthetic activity on regional to global scales.
Reanalysis of vertical mixing in mesocosm experiments: PeECE III and KOSMOS 2013
Authors: Mathesius Sabine , Getzlaff Julia , Dietze Heiner , Oschlies Andreas , Schartau Markus
Published: August 2020

Abstract. Controlled manipulation of environmental conditions within large enclosures in the ocean, so-called pelagic mesocosms, has become a standard method to explore potential responses of marine plankton communities to anthropogenic change. Among the challenges of interpreting mesocosm data is the often uncertain role of vertical mixing, which usually is not observed directly. To account for mixing nonetheless, two pragmatic assumptions are common: either that the water column is homogeneously mixed or that it is divided into two water bodies with a horizontal barrier inhibiting turbulent exchange. In this study, we present a model-based reanalysis of vertical turbulent diffusion in the mesocosm experiments PeECE III and KOSMOS 2013. Our diffusivity estimates indicate intermittent mixing events along with stagnating periods and yield simulated temperature and salinity profiles that are consistent with the observations.
Here, we provide the respective diffusivities as a comprehensive data product in the Network Common Data Format (NetCDF). This data product will help to guide forthcoming model studies that aim at deepening our understanding of biogeochemical processes in the PeECE III and KOSMOS 2013 mesocosms, such as the CO2-related changes in marine carbon export.
In addition, we make our model code available, providing an adjustable tool to simulate vertical mixing in any other pelagic mesocosm. The data product and the model code are available at https://doi.org/10.1594/PANGAEA.905311 (Mathesius et al., 2019).
ABOUT PHOTOGRAMMETRIC UAV-MAPPING: WHICH ACCURACY FOR WHICH APPLICATION?
Authors: Gressin A. , Vallet J. , Bron M.
Published: August 2020

Abstract. UAV surveys have become more and more popular over the last few years, driven by manufacturers and software suppliers who promise high accuracy at low cost. But, what are the real possibilities offered by this kind of sensor? In this article, we investigate in detail the possibilities offered by photogrammetric UAV mapping solutions through numerous practical experiments and compare them to a reference high grade LiDAR-Photogrammetric acquisition. This paper first focuses on aerial triangulation and dense matching accuracy comparison of different data acquisition units (2 types of camera) and processing softwares (1 open source and 2 proprietary softwares). Finally, the opportunities offered by these different approaches are studied in detail on standard aerial applications such as power lines detection, forest and urban areas mapping, in comparison with our reference dataset.
EXTRACTION OF ROAD EDGES FROM MLS POINT CLOUDS USING BEND ANGLE OF SCANLINES
Authors: Honma R. , Date H. , Kanai S.
Published: August 2020

Abstract. Efficient road edge extraction from point clouds acquired by Mobile Laser Scanning (MLS) is an important task because the road edge is one of the main elements of high definition maps. In this paper, we present a scanline-based road edge extraction method using a bend angle of scanlines from MLS point clouds. Scanline-based methods have advantages in that computational cost is low, it is easy to extract accurate road edges, and they are independent of driving speed of MLS compared to methods using unorganized points. In contrast, there are some problems with these methods where the extraction accuracy becomes low at curb cuts and intersections. The extraction accuracy becomes low caused by the scanning noise and small occlusion from weeds and fallen leaves. In addition, some parameters should be adjusted according to the mounting angle of the laser scanner on the vehicle. Therefore, we present a scanline-based road edge extraction method which can solve these problems. First, the points of the scanline are projected to a plane in order to reduce the influence of the mounting angle of the laser scanner on the vehicle. Next, the bend angle of each point is calculated by using filtered point clouds which are not vulnerable to small occlusions around the curb such as weeds. Then, points with a local maximum of bend angle and close to trajectories are extracted as seed points. Finally, road edges are generated by tracking based on bend angle of scanlines and smoothness of road edges from the seed points. In the experiments, our proposed methods achieved a completeness of over 95.3%, a correctness of over 95.0%, a quality of over 90.7%, and RMS difference less than 18.7 mm in total.

Precise and accurate three-dimensional geospatial data has become increasingly available thanks to advances in both Terrestrial Laser Scanning (TLS) and Structure-from-Motion Photogrammetry (SfM). These tools provide valuable information for mapping geomorphological features and detect surface changes in mountainous environments. The exploitation of 3D point-clouds has been proven tremendously useful in the field of geosciences. It remains, however, controversial whether cost efficient photogrammetry can provide as accurate and reliable geospatial information as the significantly more expensive laser scanning or not. In this study, a rockfall case site in the territory of Obergurgl, Austria, is investigated in order to provide answers to the above question in a complex environment. The analysis includes different terrestrial photogrammetry configurations aiming to comprehensively define the strengths and limitations of terrestrial photogrammetry over TLS. The latter constitutes an optimized methodology that provides guidelines for costly future assessments as part of the site investigation phase in geohazard management. There are no doubts that compared to traditional and conventional surveying methods TLS and Photogrammetry both offer products much faster and with a much higher data density. In the current study, we show that when photogrammetry is applied following a well-defined optimized strategy, it can be potentially an adequate alternative to more costly TLS datasets for mass movement assessment and monitoring purposes.

Abstract. In this paper, a combination of photogrammetric, computer-vision, and deep-learning approaches are proposed for accurate detection and quantification of cracks from the images of concrete structures. In particular, a semantic segmentation approach using UNet is applied, which is trained on a customized dataset of real-world images. Then, two photogrammetric methods are assessed for reconstructing the full figure of the cracks from stereo images. One approach is based on detecting the dominant structural plane surrounding the crack and projecting the crack pixels to this 3D plane. The second approach is based on matching the crack pixels across two images. To be able to perform the 3D reconstructions accurately, a rigorous calibration of the intrinsic calibration parameters of the cameras is performed. The relative orientation parameters between the stereo cameras are also determined in the calibration procedure. Extensive experiments are performed to evaluate each phase of this detection-and-quantification workflow. In general, cracks can be detected with an average precision of 87.48% and recall of 87.45%. They can be reconstructed in 3D with an accuracy as high as 0.05 mm.
3D DEFORMATION MEASUREMENT OF CONCRETE WALL USING CLOSE-RANGE PHOTOGRAMMETRY
Authors: Teo T.-A.
Published: August 2020

Abstract. Due to the development of digital image processing, digital photogrammetry is becoming an interesting research area in the field of structural monitoring in civil engineering. This study presents a photogrammetric measurement technique for concrete wall deformation monitoring in the destructive experiment. The non-contact photogrammetric measurement technique which provides surface deformation, is more flexible than the contacted single-point measurement technique (e.g., linear variable displacement transducers, LVDT). The major steps of the proposed scheme include (1) camera calibration, (2) orientation modeling, (3) 3D dense matching, and (4) filtering and interpolation for surface deformation. This experiment used two non-metric digital cameras to measure the deformation of a concrete wall in destructive experiment. The validation compared the image-derived and ranger-derived displacements during the experiment with mean error and standard errors of 32 epochs were −0.02mm and 0.81mm, respectively. The correlation between image-derived displacement and LVDT-derived displacement was 0.9803. The advantage of photogrammetry is to derive surface deformation which covered the whole wall during the experiment. In summary, this study demonstrated that photogrammetry is a useful measurement technique for concrete wall destructive experiment.

Abstract. Enhancing the spatial resolution of pedological information is a great
challenge in the field of digital soil mapping (DSM). Several techniques
have emerged to disaggregate conventional soil maps initially and are available at a
coarser spatial resolution than required for solving environmental and
agricultural issues. At the regional level, polygon maps represent soil
cover as a tessellation of polygons defining soil map units (SMUs), where
each SMU can include one or several soil type units (STUs) with given
proportions derived from expert knowledge. Such polygon maps can be
disaggregated at a finer spatial resolution by machine-learning algorithms,
using the Disaggregation and Harmonisation of Soil Map Units Through
Resampled Classification Trees (DSMART) algorithm. This study aimed to
compare three approaches of the spatial disaggregation of legacy soil maps based
on DSMART decision trees to test the hypothesis that the disaggregation of
soil landscape distribution rules may improve the accuracy of the resulting
soil maps. Overall, two modified DSMART algorithms (DSMART with extra soil
profiles; DSMART with soil landscape relationships) and the original DSMART
algorithm were tested. The quality of disaggregated soil maps at a 50 m
resolution was assessed over a large study area (6775 km2)
using an external validation based on 135 independent soil profiles selected
by probability sampling, 755 legacy soil profiles and existing detailed
1:25 000 soil maps. Pairwise comparisons were also performed, using the Shannon
entropy measure, to spatially locate the differences between disaggregated maps.
The main results show that adding soil landscape relationships to the
disaggregation process enhances the performance of the prediction of soil type distribution. Considering the three most probable STUs and using 135 independent soil profiles, the overall accuracy measures (the percentage of
soil profiles where predictions meet observations) are 19.8 % for DSMART
with expert rules against 18.1 % for the original DSMART and 16.9 %
for DSMART with extra soil profiles. These measures were almost 2 times
higher when validated using 3×3 windows. They achieved 28.5 % for DSMART
with soil landscape relationships and 25.3 % and 21 % for original DSMART
and DSMART with extra soil observations, respectively. In general, adding
soil landscape relationships and extra soil observations constraints allow
the model to predict a specific STU that can occur in specific environmental
conditions. Thus, including global soil landscape expert rules in the DSMART
algorithm is crucial for obtaining consistent soil maps with a clear internal
disaggregation of SMUs across the landscape.
Sink or swim? Responsible situated agency constructed by socioeconomically underprivileged students of English in neoliberal Brazil
Authors: Figueredo Carla Janaina
Published: August 2020

This article discusses the results of a four-year investigation on the neoliberal challenges faced by socioeconomically underprivileged students in Brazil who were majoring in English teaching. It is a qualitative study that employs the concept of language as a sociocultural and dialogical practice as well as the concepts of responsibility and agency; it also examines the relationship between these students’ experiences and neoliberalism as seen in language education. The data generated by questionnaires, students’ essays, and semi-structured interviews reveal that the participants’ initiatives to engage themselves in outside classroom interactions acted as counter-centralizing forces. By exercising their responsible situated agency towards their English language appropriation process, these participants react against neoliberal challenges viewed here as hierarchical centripetal forces that constrain their access to different kinds of capital. The study participants are also guided by the agency of spaces promoted by discourses marked by decolonial thinking; however, though these students find different ways to negotiate neoliberal challenges, it is still crucial that the faculty in charge of the investigated context build on existing decolonial practices in the classroom. In doing so, more students can become part of “discursive actions” that foster their responsible situated agency towards a more egalitarian society.
