Twice Is Nice: The Benefits of Two Ground Measures for Evaluating the Accuracy of Satellite-Based Sustainability Estimates
Authors: Lobell David B. , Di Tommaso Stefania , Burke Marshall , Kilic Talip
Published: August 2021

Satellite data offer great promise for improving measures related to sustainable development goals. However, assessing satellite estimates is complicated by the fact that traditional ground-based measures of these same outcomes are often very noisy, leading to underestimation of satellite performance. Here, we quantify the amount of noise in traditional measures for three commonly studied outcomes in prior work—agricultural yields, household asset ownership, and household consumption expenditures—and present a theoretical basis for properly characterizing satellite performance in the presence of noisy ground data. We find that for both yield and consumption, repeated ground measures often disagree with each other, with less than half of the variability in one ground measure captured by the other. Estimates of the performance of satellite measures, in terms of squared correlation (r2), which account for this noise in ground data are accordingly higher, and occasionally even double, the apparent performance based on a naïve comparison of satellite and ground measures. Our results caution against evaluating satellite measures without accounting for noise in ground data and emphasize the benefit of estimating that noise by collecting at least two independent ground measures.

Published: August 2021

Surface electromyogram (sEMG) signals have been used in human motion intention recognition, which has significant application prospects in the fields of rehabilitation medicine and cognitive science. However, some valuable dynamic information on upper-limb motions is lost in the process of feature extraction for sEMG signals, and there exists the fact that only a small variety of rehabilitation movements can be distinguished, and the classification accuracy is easily affected. To solve these dilemmas, first, a multiscale time–frequency information fusion representation method (MTFIFR) is proposed to obtain the time–frequency features of multichannel sEMG signals. Then, this paper designs the multiple feature fusion network (MFFN), which aims at strengthening the ability of feature extraction. Finally, a deep belief network (DBN) was introduced as the classification model of the MFFN to boost the generalization performance for more types of upper-limb movements. In the experiments, 12 kinds of upper-limb rehabilitation actions were recognized utilizing four sEMG sensors. The maximum identification accuracy was 86.10% and the average classification accuracy of the proposed MFFN was 73.49%, indicating that the time–frequency representation approach combined with the MFFN is superior to the traditional machine learning and convolutional neural network.
Robust Estimation of Contact Force and Location for Magnetic-Field-Based Soft Tactile Sensor Considering Magnetic Source Inconsistency
Authors: Yang Xiaofeng , Li Bingchu , Yang Lihong , Shen Huimin
Published: August 2021

Flexible magnetic-field-based tactile sensors (FMFTS) have numerous advantages including low cost, ease of manufacture, simple wiring, high sensitivity, and so on. Flexible magnetic-field-based tactile sensors need to be calibrated before use to build accurate mapping between contact force and magnetic field intensity measured by magnetic sensors; however, when considering remanence inconsistency of magnetic source, each FMFTS needs to be calibrated independently to enhance accuracy, and the complex preparation prevents FMFTS from being used conveniently. A robust estimation method of contact force and location that can tolerate remanence inconsistency of magnetic source in FMFTS is proposed. Firstly, the position and orientation of magnetic source were tracked using the Levenberg–Marquart algorithm, and the tracking results were insensitive to the remanence of magnetic source with appropriate cost function. Secondly, the mapping between magnitude and location of contact force and position and orientation of magnetic source was built with calibration of one sensor; the mapping only depends on the structural response of flexible substrate, and thus can be extended to estimate external force and location for other sensors with the same structure. The proposed method was evaluated in both simulations and experiments, and the results confirm that the estimation of magnitude and location of external force for FMFTS with the same structure and different remanence could reach acceptable accuracy, depending on single calibration. The proposed method can be used to simplify the calibration procedure and remove the barrier for large-scale application of FMFTS and replacement of damaged FMFTS.

Environmental Noise Classification with Inception-Dense Blocks for Hearing Aids
Authors: Ting Po-Jung , Ruan Shanq-Jang , Li Lieber Po-Hung
Published: August 2021

Hearing aids are increasingly essential for people with hearing loss. For this purpose, environmental noise estimation and classification are some of the required technologies. However, some noise classifiers utilize multiple audio features, which cause intense computation. In addition, such noise classifiers employ inputs of different time lengths, which may affect classification performance. Thus, this paper proposes a model architecture for noise classification, and performs experiments with three different audio segment time lengths. The proposed model attains fewer floating-point operations and parameters by utilizing the log-scaled mel-spectrogram as an input feature. The proposed models are evaluated with classification accuracy, computational complexity, trainable parameters, and inference time on the UrbanSound8k dataset and HANS dataset. The experimental results showed that the proposed model outperforms other models on two datasets. Furthermore, compared with other models, the proposed model reduces model complexity and inference time while maintaining classification accuracy. As a result, the proposed noise classification for hearing aids offers less computational complexity without compromising performance.

Published: August 2021

This research aims to: (1) examine the construct social dominance orientation (SDO) in a setting that expands group hierarchy to include prejudices and dominance toward animals; (2) compare predictive validity and internal consistency between the 16-item SDO6 and the 4-item SSDO; and (3) test whether the SDO6 and the SSDO scales predict well in a consumer behavior oriented contextual setting. Predictive validity of the SSDO was almost as high as that of the SSD6; internal reliability, however, was considerably lower. Further, as hypothesized, individuals exhibiting lower levels of SDO, as assessed by both SDO6 and SSDO, exhibit lower levels of speciesism as well as higher levels of empathic concern. In addition, as hypothesized, ethical vegans, as compared to carnists, display lower levels of SDO and speciesism, and higher levels of empathic concern.
Identification and Prioritization of Critical Success Factors for Off-Site Construction Using ISM and MICMAC Analysis
Authors: Jung Seoyoung , Lee Seulki , Yu Jungho
Published: August 2021

Many studies have been conducted to define the critical success factors (CSFs) for off-site construction (OSC) activation, but there has been a lack of identification of the relationship with the identified CSFs. However, it is necessary to clearly identify the hierarchy and relationships with the success factors in order to develop specific strategies for OSC activation. This work presents a study that was conducted to identify the CSFs for OSCs and establish the relationships of the identified CSFs for OSC. First, 20 CSFs for OSCs were identified through prior study reviews related to CSFs for OSC. Next, the interpretive structural modeling (ISM), which has advantages in developing an understanding of complex relationships, was leveraged in order to analyze the relationships between 20 CSFs for OSC to derive a hierarchical model consisting of seven levels. The CSFs for OSC were classified into four groups using MICMAC analysis, which is useful for classifying factors by the strength of the relationship with factors based on driving power and dependence power. This proposed model can be used as a basis for developing management measures for OSC project success.

Published: August 2021

This study aims to: (1) investigate the amount of corporate social and environmental responsibility (CSR) spending, awards, and activities of listed companies in the Stock Exchange of Thailand (SET) and in the Market for Alternative Investment (MAI); (2) test the impact of CSR spending, awards, and financial performance activities; and (3) examine the amount of CSR spending, awards, and activities between companies with and without a CSR committee. The sample included all the listed companies in the resource industry from the SET and the MAI. The data were collected from the companies’ annual reports from 2015 to 2019. Descriptive analysis, an independent-sample t-test, a correlation matrix, and an unbalanced panel data analysis were used to analyze the data. The average level of spending per activity was 2.2964 million baht. There were, on average, 2.1741 awards and 11.4178 activities during the studied period. Moreover, there was a significant negative impact of CSR spending, and a positive impact of CSR awards and activities, on corporate financial performance. Finally, there was a significantly different amount of CSR spending, awards, and activities between the companies with and without a CSR committee. The findings of this study demonstrate that legitimacy theory can be used to explain the benefit of CSR to Thai-listed companies, although CSR is still a voluntary corporate responsibility in Thailand.

Published: August 2021

This study proposes a geographic information system (GIS)-based cellular automata (CA) model, which is designed for planning bikeways upon existing footpath networks within an urban area. The CA model was developed based on a GIS platform as a visual interface whereby spatiotemporal characteristics and spatial processing can be combined in a highly effective way. The host value of each CA cell is conditioned upon four indicator variables, namely cycling demand level, land-use nature, social value, and traffic safety. This model gives traffic planners a quick and intuitive framework to develop cycling facilities under limited land resources. A model prototype has been developed in a common desktop GIS and applied to a mid-sized rapidly developing area in Singapore.

Published: August 2021

The purpose of this study is to further improve the road performance and emission reduction effect of tourmaline-modified asphalt. Graphene was used to enhance the performance of tourmaline-modified asphalt, and graphene/tourmaline-composite-modified asphalt was prepared. The temperature susceptibility, high temperature, anti-aging properties and rheological performance of the modified asphalt were studied. The test method of emission reduction efficiency of the modified asphalt and its mixture was proposed. The emission reduction effect of different modified asphalts and its mixture was evaluated. The enhancement effect of graphene on the properties of tourmaline-modified asphalt was confirmed. It provides a reference for the performance enhancement of inorganic material modified asphalt. The results show that the temperature susceptibility, high temperature, anti-aging properties and rheological performance of the graphene/tourmaline-composite-modified asphalt are better than those of the tourmaline-modified asphalt and base asphalt. The asphalt fume reduction rate of graphene/tourmaline-composite-modified asphalt is higher than that of tourmaline-modified asphalt. With the increase of graphene content, the emission reduction performance increases gradually, and the enhancement effect of graphene on tourmaline performance is more obvious.

Published: August 2021

Water, energy, land, and food are vital elements with multiple interactions. In this context, the concept of a water–energy–food (WEF) nexus was manifested as a natural resource management approach, aiming at promoting sustainable development at the international, national, or local level and eliminating the negative effects that result from the use of each of the four resources against the other three. At the same time, the transition to green energy through the application of renewable energy technologies is changing and perplexing the relationships between the constituent elements of the nexus, introducing new conflicts, particularly related to land use for energy production vs. food. Specifically, one of the most widespread “green” technologies is photovoltaic (PV) solar energy, now being the third foremost renewable energy source in terms of global installed capacity. However, the growing development of PV systems results in ever expanding occupation of agricultural lands, which are most advantageous for siting PV parks. Using as study area the Thessaly Plain, the largest agricultural area in Greece, we investigate the relationship between photovoltaic power plant development and food production in an attempt to reveal both their conflicts and their synergies.
A Grounded Theory of Pro-Nature Behaviour: From Moral Concern to Sustained Action
Authors: Williams Marc O. , Whitmarsh Lorraine , Haddock Geoffrey , Mac Giolla Chríost Diarmait
Published: August 2021

Worldwide ecosystem decline is a pressing issue that has led governments to sign up to biodiversity-related targets, but little is known about what drives individuals’ conservation behaviour. This study uses a qualitative methodology (grounded theory) to understand what leads to pro-nature attitudes and behaviours. Twenty participants (10 men; 10 women) underwent semi-structured interviews and audio files were transcribed and coded to form the basis of theory. The authors propose a model based on interview material in which species with intrinsic value (i.e., deemed valuable in their own right, not for their usefulness to humans) are within the bounds of moral consideration. Individuals with generalised beliefs about the intrinsic value of non-human species expressed moral concern for human-caused impacts on nature. External prompts, including social messages, were associated with sporadic pro-nature behaviours. Individuals engaging in sustained behaviour showed evidence of having internalised moral standard of pro-nature actions and also appeared to fashion a social environment that would sustain and enhance their moral views. We discuss the implications of our findings with respect to conservation campaign messaging and government policy.
Green Artificial Intelligence: Towards an Efficient, Sustainable and Equitable Technology for Smart Cities and Futures
Authors: Yigitcanlar Tan , Mehmood Rashid , Corchado Juan M.
Published: August 2021

Smart cities and artificial intelligence (AI) are among the most popular discourses in urban policy circles. Most attempts at using AI to improve efficiencies in cities have nevertheless either struggled or failed to accomplish the smart city transformation. This is mainly due to short-sighted, technologically determined and reductionist AI approaches being applied to complex urbanization problems. Besides this, as smart cities are underpinned by our ability to engage with our environments, analyze them, and make efficient, sustainable and equitable decisions, the need for a green AI approach is intensified. This perspective paper, reflecting authors’ opinions and interpretations, concentrates on the “green AI” concept as an enabler of the smart city transformation, as it offers the opportunity to move away from purely technocentric efficiency solutions towards efficient, sustainable and equitable solutions capable of realizing the desired urban futures. The aim of this perspective paper is two-fold: first, to highlight the fundamental shortfalls in mainstream AI system conceptualization and practice, and second, to advocate the need for a consolidated AI approach—i.e., green AI—to further support smart city transformation. The methodological approach includes a thorough appraisal of the current AI and smart city literatures, practices, developments, trends and applications. The paper informs authorities and planners on the importance of the adoption and deployment of AI systems that address efficiency, sustainability and equity issues in cities.
A Feature Combination-Based Graph Convolutional Neural Network Model for Relation Extraction
Authors: Xu Jinling , Chen Yanping , Qin Yongbin , Huang Ruizhang , Zheng Qinghua
Published: August 2021

The task to extract relations tries to identify relationships between two named entities in a sentence. Because a sentence usually contains several named entities, capturing structural information of a sentence is important to support this task. Currently, graph neural networks are widely implemented to support relation extraction, in which dependency trees are employed to generate adjacent matrices for encoding structural information of a sentence. Because parsing a sentence is error-prone, it influences the performance of a graph neural network. On the other hand, a sentence is structuralized by several named entities, which precisely segment a sentence into several parts. Different features can be combined by prior knowledge and experience, which are effective to initialize a symmetric adjacent matrix for a graph neural network. Based on this phenomenon, we proposed a feature combination-based graph convolutional neural network model (FC-GCN). It has the advantages of encoding structural information of a sentence, considering prior knowledge, and avoiding errors caused by parsing. In the experiments, the results show significant improvement, which outperform existing state-of-the-art performances.

Published: August 2021

α-conotoxins are 13–19 amino acid toxin peptides that bind various nicotinic acetylcholine receptor (nAChR) subtypes. α-conotoxin Mr1.7c (MrIC) is a 17 amino acid peptide that targets α7 nAChR. Although MrIC has no activating effect on α7 nAChR when applied by itself, it evokes a large response when co-applied with the type II positive allosteric modulator PNU-120596, which potentiates the α7 nAChR response by recovering it from a desensitized state. A lack of standalone activity, despite activation upon co-application with a positive allosteric modulator, was previously observed for molecules that bind to an extracellular domain allosteric activation (AA) site at the vestibule of the receptor. We hypothesized that MrIC may activate α7 nAChR allosterically through this site. We ran voltage-clamp electrophysiology experiments and in silico peptide docking calculations in order to gather evidence in support of α7 nAChR activation by MrIC through the AA site. The experiments with the wild-type α7 nAChR supported an allosteric mode of action, which was confirmed by the significantly increased MrIC + PNU-120596 responses of three α7 nAChR AA site mutants that were designed in silico to improve MrIC binding. Overall, our results shed light on the allosteric activation of α7 nAChR by MrIC and suggest the involvement of the AA site.

Phleboviruses are arboviruses transmitted by sand flies, mosquitoes and ticks. Some sand fly-borne phleboviruses cause illnesses in humans, such as the summer fevers caused by the Sicilian and Naples viruses or meningitis caused by the Toscana virus. Indeed, traces of several phleboviral infections have been serologically detected in domestic animals, but their potential pathogenic role in vertebrates other than humans is still unclear, as is the role of vertebrates as potential reservoirs of these viruses. In this study, we report the results of a serological survey performed on domestic animals sampled in Northern Italy, against four phleboviruses isolated from sand flies in the same area. The sera of 23 dogs, 165 sheep and 23 goats were tested with a virus neutralization assay for Toscana virus, Fermo virus, Ponticelli I virus and Ponticelli III virus. Neutralizing antibodies against one or more phleboviruses were detected in four out of 23 dogs, 31 out of 165 sheep and 12 out of 23 goats. This study shows preliminary evidence for the distribution pattern of phleboviral infections in different animal species, highlighting the potential infection of the Toscana virus in dogs and the Fermo virus in goats.

The novel coronavirus SARS-CoV-2 is the seventh identified human coronavirus. Understanding the extent of pre-existing immunity induced by seropositivity to endemic seasonal coronaviruses and the impact of cross-reactivity on COVID-19 disease progression remains a key research question in immunity to SARS-CoV-2 and the immunopathology of COVID-2019 disease. This paper describes a panel of lentiviral pseudotypes bearing the spike (S) proteins for each of the seven human coronaviruses (HCoVs), generated under similar conditions optimized for high titre production allowing a high-throughput investigation of antibody neutralization breadth. Optimal production conditions and most readily available permissive target cell lines were determined for spike-mediated entry by each HCoV pseudotype: SARS-CoV-1, SARS-CoV-2 and HCoV-NL63 best transduced HEK293T/17 cells transfected with ACE2 and TMPRSS2, HCoV-229E and MERS-CoV preferentially entered HUH7 cells, and CHO cells were most permissive for the seasonal betacoronavirus HCoV-HKU1. Entry of ACE2 using pseudotypes was enhanced by ACE2 and TMPRSS2 expression in target cells, whilst TMPRSS2 transfection rendered HEK293T/17 cells permissive for HCoV-HKU1 and HCoV-OC43 entry. Additionally, pseudotype viruses were produced bearing additional coronavirus surface proteins, including the SARS-CoV-2 Envelope (E) and Membrane (M) proteins and HCoV-OC43/HCoV-HKU1 Haemagglutinin-Esterase (HE) proteins. This panel of lentiviral pseudotypes provides a safe, rapidly quantifiable and high-throughput tool for serological comparison of pan-coronavirus neutralizing responses; this can be used to elucidate antibody dynamics against individual coronaviruses and the effects of antibody cross-reactivity on clinical outcome following natural infection or vaccination.

Authors: KADER M.A. , HOSSAIN M.A. , HASAN M.R.
Published: August 2021

A study was undertaken to analyse and compare the nutrient content of some commercial fish feeds available in Bangladesh through chemical analysis. The commercial fish feeds collected from the markets were Quality Feeds Ltd. (QF), Aftab Feed Products Ltd. (AF), Saudi-Bangla Fish Feed Ltd. (SBF), Paragon Feeds Ltd. (PF) and AIT Feeds Ltd. (AIT). Proximate composition such as moisture, crude protein, crude lipid, ash, fibre and NFE (nitrogen free extract), and some of the macro minerals such as Ca, P, Na, K and S were analysed. In general, there was no large variation between analysed and company declared nutrient contents of different feeds except the protein and lipid content of some feeds. However, two pangas feeds such as Surovi (nursery and grower) of QF had much lower protein content (27.57% and 20.24%) compared to 32% and 25% protein value respectively declared by the company. Similarly, large (more than 5%) differences between the analysed and company declared protein content was observed in case of carp starter and grower feeds of QF. On the other hand, analysed protein content of all feeds of SBF was more than that declared by the company except for special shrimp feed which had slightly lower (1%) protein compared to the company declared value. Pangas feeds (grower I and II) of PF had about 3% lower protein than the company declared value. The analysed lipid contents of all feeds were higher than the company declared values except nursery feeds of QF which had about 1-2% less lipid content compared to the company declared value. Fibre contents of different feeds analysed were much higher (3-5%) than the company declared values. The analysed mineral contents in all the feeds were higher than the recommended mineral requirement for fishes. The results of the study showed that on the basis of nutrient content feeds from Saudi-Bangla Fish Feed Ltd. is better than other feeds.

This study was carried out in four selected stations (Mohonpur, Kaligonj, Charludua and Daulatkhan) in the Meghna river system, Bangladesh between the latitude 22°35.494Ñ N - 23°23.987 N and longitude 90°35.793 E - 90°49.061Ñ E. Average net primary production (NPP) and gross primary production (GPP) (gC·m3 ·h) in the euphotic zone of the Meghna river were 0.089 ± 0.021 and 0.161 ± 0.025 respectively. The rate of conversion of GPP into NPP ranged between 48.17 and 62.63% with an average of 54.72%. The mean ratio of NPP to GPP (NPP:GPP), NPP:Respiration and average percent respiration rate to GPP were 0.549 ± 0.060, 1.251 ± 0.320 and 45.04 ± 6.02% respectively. The mean photosynthetic production for the day (gC·m3 ·day) and year (gC·m3 ·yr) were 1.930 and 704.45 respectively. Annual computed fish yield in relation to gross carbon synthesis was 7.0 kg fish·m3 ·year. The actual production of fish from the Meghna river is accounted about 0.21% of the estimated production. The gross energy production (Kcal energy·m3 ·day) by the producers was estimated about 18.0. The NPP of phytoplankton established a high significant negative correlation (r = -0.975; p < 0.01) with water temperature and low, but a definite negative correlation existed (r = -0.767) between GPP and water temperature.

The mud crab, Scylla serrata and blue swimming crab, Portunus pelagicus were chosen for crab fattening which is ‘First of its kind’ in India and the women are successful in fattening and creating alternate income through this project. Between these two crabs, fattening of P. pelagicus is more attractive due to the short fattening span and the low price quoted on molted crabs at the auction sheds. The participation of women and the effectiveness of this project are discussed in this paper.

Knowledge Management (KM) systems were implemented widely in corporate organizations for past three decades, but there is little research on KM in schools. The key objectives of this study are to identify the major components of School Knowledge Management and analyze the impact of KM in secondary education on academic performance, based on the perception of school teachers. The survey-based study is conducted in government schools of an Indian State. Exploratory Factor Analysis and Binary Logistic Regression methods are used to identify the KM factors and their impact on academic performance. This study identified the processes and enablers of school KM and its impact on academic performance. Academic performance, being mentioned as the primary outcome of School KM has not been empirically tested from a School KM perspective earlier. Knowledge creation, technology infrastructure and teacher’s competency are identified as KM variables that can significantly influence the Academic Performance and therefore the schools can initiate policies and methods to improve these vital factors.

Genetic relationships between important attributes in studying sugarcane populations through breeding and direct selection, are crucialto understand how changes made by selecting one character may cause changes in others. The study aimed to determine the best yielding sugarcane genotypes tested at early selection stage under sprinkler irrigation, in comparison with a check variety (R579). The experiment was designed following a randomized complete block (RCB), with 30 cane genotypes in three replications. Each plot consisted of five dual rows of ten meters, with 0.5 and 1.90 m of inter-row spacing, i.e. 95 m² per plot and nearly 6,000 m² for the whole experiment. It was carried out on a commercial sugarcane plantation of Ferké 2, in northern Ivory Coast, over two seasons (plant cane and first ratoon) as an early-season crop from, November 29, 2018 to October 26, 2020. In each micro-plot, different agro-morphological traits were collected at harvest from three central dual rows.

Authors: Stevanus Kalis
Published: August 2021

Abstract; The discussion of the preaching of the gospel cannot be separated from the doctrine of the supremacy of Christ as the only way of salvation. In the context of a pluralist Indonesian society, the author tries to give an understanding of the supremacy of Christ and its relevance to the preaching of the Gospel based on John 14:6 so that Christians are not influenced by pluralism. Through the exegetical approach to the text of the Gospel of John 14:6, it is obtained the meaning of the supremacy of Christ which is stated by John that He is the only way of salvation or the true Savior. This is a relevant message to be expressed in the ministry of preaching the gospel.
Abstrak; pembahasan mengenai pemberitaan Injil tidak dapat dipisahkan dari doktrin tentang supremasi Kristus sebagai satu-satunya jalan keselamatan. Dalam konteks masyarakat Indonesia yang pluralis, penulis mencoba untuk memberi pemahaman tentang supremasi Kristus dan relevansinya bagi pemberitaan Injil berdasarkan Yohanes 14:6 sehingga umat Kristen tidak terpengaruh pluralisme. Melalui pendekatan eksegetikal pada teks Injil Yohanes 14:6 tersebut diperoleh makna tentang supremasi Kristus yang dinyatakan Yohanes bahwa Dia adalah satu-satunya jalan keselamatan atau Juruselamat sejati. Hal ini menjadi berita yang relevan untuk dinyatakan dalam pelayanan pemberitaan Injil.
Reconociendo “riesgos invisibles” en una “zona de sacrificio”:
Authors: Lincura Matamala Oliver , Díaz Crovetto Gonzalo
Published: August 2021

Este artículo presenta, por un lado, el proceso histórico de construcción social del riesgo en una “Zona de Sacrificio”, discutiendo acerca de distintas vulnerabilidades que afectan al territorio, sus habitantes y trabajadores; y, por otro lado, centra su discusión en el proceso de reconocimiento y alteración de la percepción social del riesgo de trabajadores afectados y organizados en torno al asbesto. Para esto último, el trabajo sitúa la trayectoria de la agrupación Trabajadores Unidos Contra el Asbesto (TUCA), organización que reúne a gran parte de los trabajadores que se vieron afectados y expuestos a una contaminación por inhalación de asbesto en un trabajo de remoción de éste desde una central termoeléctrica. La investigación se fundamenta en un proceso de inmersión etnográfica, que contempló la partición en eventos y entrevistas etnográficas para dar cuenta del proceso de reconocimiento en torno al “asbesto” como una amenaza para la salud por parte de los trabajadores afectados. Asimismo, se revisaron antecedentes generales, historiográficos, estadísticos, de literatura especializada y de material de prensa, para presentar tanto antecedentes de este proceso de reconocimiento del riesgo como para describir la construcción social del riesgo de una “Zona de Sacrificio”.
Küpalme (la descendencia) como saber educativo intercultural desde la mirada de los Kimche (sabios) del pueblo Mapuche
Authors: Morales Mendoza Karla , Berlanga Adell María Jesús , Maldonado García Fabiola , Sanhueza Henríquez Susan
Published: August 2021

El pensarse vinculado con otros o como parte de un ser juntos implica procesos y prácticas cotidianas de construcción de vínculos que se conectan con procesos de memoria en contextos políticos más amplios (Carsten, 2007). En este contexto, nos propusimos analizar los significados que las familias mapuches otorgaban al küpalme en la educación de niños y niñas. Optamos por una metodología cualitativa a través de entrevistas a kimche y xemkeche de comunidades indígenas de la IX región de la Araucanía, Chile. Los discursos muestran como el Küpalme está asociado a la herencia social, cultural y espiritual del ser mapuche y como ciertos elementos culturales, territoriales, sanguíneos y vivenciales van configurando los saberes, que luego son transmitidos a los descendientes mediante diferentes sistemas de comunicación ancestral. Los resultados ponen en valor la perspectiva educativa intercultural del Küpalme, como elemento central en los procesos de construción de la identidad de niños y niñas mapuche.

Modelagem estocástica usando a distribuição generalizada de valores extremos e momentos LH: uma abordagem via software livre R
Authors: Pansera Wagner Alessandro , Gomes Bendito Martins
Published: August 2021

A distribuição de probabilidade generalizada de valores extremos (GEV) é utilizada na modelagem de extremos naturais, tais como: chuvas intensas, vazões máximas, velocidade do vento e temperatura. Uma questão importante na utilização da GEV é a escolha da metodologia de estimativa de parâmetros. As metodologias comumente utilizadas são a máxima verossimilhança e os momentos convencionais. Contudo, estudos apontam que tais metodologias nem sempre produzem estimativas confiáveis dos parâmetros da GEV. Nesse sentido, é interessante a utilização dos momentos LH, pois caracterizam melhor o caudal superior da distribuição devido ênfase dada aos maiores valores observados. Porém, não existem rotinas computacionais desenvolvidas para utilização da GEV com momentos LH em software livre. Dessa forma, esta pesquisa teve por objetivo desenvolver uma rotina computacional no software livre R para modelagem estocástica por meio da GEV, utilizando momentos LH para estimar seus parâmetros e verificar a qualidade do ajuste. Foram utilizados dados de vazões máximas diárias anuais disponíveis na literatura para demonstrar a aplicabilidade da rotina computacional. Esta pesquisa contribui para disseminar o uso dos momentos LH e facilitar modelagem estocástica de eventos ambientais extremos.
