Human Hand Anatomy-Based Prosthetic Hand
Authors: Dunai Larisa , Novak Martin , García Espert Carmen
Published: December 2020

The present paper describes the development of a prosthetic hand based on human hand anatomy. The hand phalanges are printed with 3D printing with Polylactic Acid material. One of the main contributions is the investigation on the prosthetic hand joins; the proposed design enables one to create personalized joins that provide the prosthetic hand a high level of movement by increasing the degrees of freedom of the fingers. Moreover, the driven wire tendons show a progressive grasping movement, being the friction of the tendons with the phalanges very low. Another important point is the use of force sensitive resistors (FSR) for simulating the hand touch pressure. These are used for the grasping stop simulating touch pressure of the fingers. Surface Electromyogram (EMG) sensors allow the user to control the prosthetic hand-grasping start. Their use may provide the prosthetic hand the possibility of the classification of the hand movements. The practical results included in the paper prove the importance of the soft joins for the object manipulation and to get adapted to the object surface. Finally, the force sensitive sensors allow the prosthesis to actuate more naturally by adding conditions and classifications to the Electromyogram sensor.
Real-Time Plane Detection with Consistency from Point Cloud Sequences
Authors: Xu Jinxuan , Xie Qian , Chen Honghua , Wang Jun
Published: December 2020

Real-time consistent plane detection (RCPD) from structured point cloud sequences facilitates various high-level computer vision and robotic tasks. However, it remains a challenge. Existing techniques for plane detection suffer from a long running time or the problem that the plane detection result is not precise. Meanwhile, labels of planes are not consistent over the whole image sequence due to plane loss in the detection stage. In order to resolve these issues, we propose a novel superpixel-based real-time plane detection approach, while keeping their consistencies over frames simultaneously. In summary, our method has the following key contributions: (i) a real-time plane detection algorithm to extract planes from raw structured three-dimensional (3D) point clouds collected by depth sensors; (ii) a superpixel-based segmentation method to make the detected plane exactly match its actual boundary; and, (iii) a robust strategy to recover the missing planes by utilizing the contextual correspondences information in adjacent frames. Extensive visual and numerical experiments demonstrate that our method outperforms state-of-the-art methods in terms of efficiency and accuracy.
An Ultra-Short Baseline Underwater Positioning System with Kalman Filtering

Published: December 2020

The ultra-short baseline underwater positioning is one of the most widely applied methods in underwater positioning and navigation due to its simplicity, efficiency, low cost, and accuracy. However, there exists environmental noise, which has negative impacts on the positioning accuracy during the ultra-short baseline (USBL) positioning process, which results in a large positioning error. The positioning result may lead to wrong decision-making in the latter processing. So, it is necessary to consider the error sources, and take effective measurements to minimize the negative impact of the noise. In our work, we propose a USBL positioning system with Kalman filtering to improve the positioning accuracy. In this system, we first explore a new kind of element array to accurately capture the acoustic signals from the object. We then organically combine the Kalman filters with the array elements to filter the acoustic signals, using the minimum mean-square error rule to obtain accurate acoustic signals. We got the high-precision phase difference information based on the non-equidistant quaternary original array and the phase difference acquisition mechanism. Finally, on account of the obtained accurate phase difference information and position calculation, we determined the coordinates of the underwater target. Comprehensive evaluation results demonstrate that our proposed USBL positioning method based on the Kalman filter algorithm can effectively enhance the positioning accuracy.
Value Co-Creation and Satisfaction in B2B Context: A Triadic Study in the Furniture Industry
Authors: Sales-Vivó Vicente , Gil-Saura Irene , Gallarza Martina G.
Published: December 2020

Research on Value co-Creation (VcC) has been more extensive in B2C (business-to-consumer) than in B2B (business-to-business) and mainly for service contexts, under dyadic approaches (supplier–client). Moreover, research has paid little attention to the impacts of VcC on Satisfaction in its duality: Social and Economic Satisfaction. As a novelty, this study examines VcC in B2B industrial relationships in the triad of supplier–manufacturer–client. A model proposes VcC as an antecedent of manufacturer’s Economic Satisfaction, with the mediating role of Social Satisfaction. The model is empirically contrasted for a sample of 77 firms from an industrial panel—the Spanish Furniture Market Observatory. The triadic approach is depicted with bi-directional relationships of the manufacturer with its main supplier and main client). Results evidence that VcC and Economic Satisfaction are greater in the manufacturer–main client relationship. Moreover, the manufacturer’s Satisfaction relies on its social dimension, which has a key role to produce Economic Satisfaction. Results also show asymmetry in the supply chain, different from those with the main supplier. Implications for managers invite to achieve a long-term VcC chain with all business partners, the focus being on manufacturer’s social dimension, so the triad supplier–manufacturer–client could be better aligned.

Published: December 2020

There is a need to apply lean approaches in construction projects. Both BIM and IoT are increasingly being used in the construction industry. However, using BIM in conjunction with IoT for sustainability purposes has not received enough attention in construction. In particular, the capability created from the combination of both technologies has not been exploited. There is a growing consensus that the future of construction operation tends to be smart and intelligent, which would be possible by a combination of both information systems and sensors. This investigation aims to find out the recent efforts of utilizing BIM for lean purposes in the last decade by critically reviewing the published literature and identifying dominant clusters of research topics. More specifically, the investigation is further developed by identifying the gaps in the literature to utilize IoT in conjunction with BIM in construction projects to facilitate applying lean techniques in a more efficient way in construction projects. A systematic review method was designed to identify scholarly papers covering both concepts “lean” and “BIM” in construction and possibilities of using IoT. A total of 48 scholarly articles selected from 26 construction journals were carefully reviewed thorough perusal. The key findings were discussed with industry practitioners. The transcriptions were analyzed employing two coding and cluster analysis techniques. The results of the cluster analysis show two main directions, including the recent practice of lean and BIM interactions and issues of lean and BIM adoption. Findings revealed a large synergy between lean and BIM in control interactions and reduction in variations, and surprisingly there are many uncovered areas in this field. The results also show that the capability of IoT is also largely not considered in recent developments. The number of papers covering both lean and BIM is very limited, and there is a large clear gap in understanding synergetic interactions of lean concepts applying in BIM and IoT in specific fields of construction such as sustainable infrastructure projects.

Published: December 2020

The contradiction between industrial economic development and the ecological environment in Northwest China is prominent, so the green transformation of industrial economy in this region is imperative. From the perspective of industrial ecology, this study uses economic and environmental statistics from Northwest China from 2006 to 2018 as well as the Krugman specialization index and entropy index methods to calculate the degree of different types of industrial agglomeration in Northwest China. The eco-efficiency of Northwest China is calculated by the global SBM-DDF model. On this basis, the stochastic effect panel tobit regression model is used to analyze the influence and mechanism of different types of industrial agglomeration on eco-efficiency in Northwest China. The results show that the concentration of specialization has a significantly negative effect on the eco-efficiency of Northwest China at the level of 1%. Excepting Ningxia, the eco-efficiency of other provinces has been improved with the decrease of industrial specialization. The influence of the related diversification agglomeration on the eco-efficiency in Northwest China shows a U curve. The degree of industrial correlation diversification in Qinghai and Ningxia is less than the critical value 1.45, whereas Shaanxi, Gansu, and Xinjiang have crossed the inflection point. The unrelated diversification agglomeration has a negative effect on the eco-efficiency of Northwest China at the level of 1%, and the degree of industrial independent diversification in Shaanxi Province has decreased slightly, which is beneficial to the improvement of eco-efficiency. By contrast, other provinces have increased considerably. The conclusion can provide a theoretical basis for industrial green transformation path selection and related policy formulation in Northwest China.

Published: December 2020

The uptake of Electric Vehicles (EVs) is rapidly changing the landscape of urban mobility services. Transportation Network Companies (TNCs) have been following this trend by increasing the number of EVs in their fleets. Recently, major TNCs have explored the prospect of establishing privately owned charging facilities that will enable faster and more economic charging. Given the scale and complexity of TNC operations, such decisions need to consider both the requirements of TNCs and local planning regulations. Therefore, an optimisation approach is presented to model the placement of CSs with the objective of minimising the empty time travelled to the nearest CS for recharging as well as the installation cost. An agent based simulation model has been set in the area of Chicago to derive the recharging spots of the TNC vehicles, and in turn derive the charging demand. A mathematical formulation for the resulting optimisation problem is provided alongside a genetic algorithm that can produce solutions for large problem instances. Our results refer to a representative set of the total data for Chicago and indicate that nearly 180 CSs need to be installed to handle the demand of a TNC fleet of 3000 vehicles.

Published: December 2020

Mali is a major livestock producing country in West Africa. However, in recent years, the sector has faced multiple challenges like farmer-herder conflicts, overuse of grazing and water resources, and the effects of climate change. Meanwhile, traditional livestock systems are becoming less important given the increased availability of vehicular transport for regional and international animal trade as well as new opportunities for more specialised urban and peri-urban production systems. To assess the role of Mali’s capital city Bamako for livestock consumption and trade, this study examined the scale of livestock movement in the city, comprising influxes, outfluxes, and transits. To this end, flows of cattle, small ruminants, and livestock feed were recorded through road surveys covering three different seasons. The results showed the role of Bamako as a major trade hub in the distribution of ruminants. While traffic of cattle and sheep was regional, movement of goats was smaller and more localised. Religious festivals were an important driver of livestock traffic, both in terms of the numbers of livestock and the distance covered. This study highlights the role of cities for livestock mobility and contributes to a better understanding of challenges related to urban livestock production and trade and its requirements for better livestock management.

Authors: Fuentes-Bargues José Luis , Bastante-Ceca Mª José , Ferrer-Gisbert Pablo Sebastián , González-Cruz Mª Carmen
Published: December 2020

Construction is one of the most important sectors in terms of economic volume and number of employees. It represents approximately 10% of the Gross Domestic Product of the European Union and employs 7% of its total labour force. In a construction project, procurement is employed in many of the stages, so it can constitute an adequate mechanism to integrate sustainability initiatives. Research concerning economic aspects in procurement has always been present in the construction sector, whereas research related to environmental aspects has been gaining attention in the last years. Nevertheless, social aspects are still not very present in the literature on public procurement. The main objective of this research is to analyse the use of social criteria in public tendering processes of public works in the Valencian region of Spain. The results show that Valencian public entities include social criteria for the 11.7% of adjudicated public works. This value is very low when compared with other studies developed in different countries worldwide. Social criteria, just like in other cases, are used more frequently the larger the budget of the project and the longer the execution time. The average weight of social criteria for the tendering process is low (7.0 out of 100), although entities that usually consider these criteria are aware of their importance and give them a higher weight, in global terms.
Does Green Energy Complement Economic Growth for Achieving Environmental Sustainability? Evidence from Saudi Arabia
Authors: Kahia Montassar , Omri Anis , Jarraya Bilel
Published: December 2020

This study extends previous environmental sustainability literature by investigating the joint impact of economic growth and renewable energy on reducing CO2 emissions in Saudi Arabia over the period 1990–2016. Using the fully modified ordinary least-square (FMOLS) and dynamic ordinary least-square DOLS estimators, we find that economic growth increases CO2 emissions in all estimated models. Moreover, the validity of the environmental Kuznets curve (EKC) hypothesis is only supported for CO2 emissions from liquid fuel consumption. The invalidity of the EKC hypothesis in the most commonly used models implies that economic growth alone is not sufficient to enhance environmental quality. Renewable energy is found to have a weak influence on reducing the indicators of environmental degradation. We also find that the joint impact of renewable energy consumption and economic growth on the indicators of CO2 emissions is negative and insignificant for all the estimated models, meaning that the level of renewable energy consumption in Saudi Arabia is not sufficient to moderate the negative effect of economic growth on environmental quality. Implications for policy are also discussed.
Pulses for Healthy and Sustainable Food Systems: The Effect of Origin on Market Price
Authors: Acciani Claudio , De Boni Annalisa , Bozzo Francesco , Roma Rocco
Published: December 2020

Pulses are widely acknowledged for their high nutritional value due to high protein content, low content in calories, and low glycemic index; they are a good alternative to animal proteins thus offering a considerable number of social, environmental, and health benefits. Despite pulses being widely acknowledged as healthy and sustainable food, in mainly European countries, consumption is growing but still lower than the recommended level, production is unprofitable in comparison to the current market prices level, and a reduction in harvested area has led to a strong dependence on import for pulses supply. Pulses are particularly fitting to the feature of local food because they can be suitably grown in any context, even in the most complex areas, and consumer interest and awareness of food origin has strongly increased in recent years. Lentils were selected as a case study in this paper that aims to define which features are effective on market price and, in particular, the role of origin declaration on label plays in defining the market price and how the origin attributes may enhance market price and farms competitiveness. The methodological tool for this investigation is the hedonic price model, useful to explain the effects of attributes of pulses affecting the market price. Results contribute to a better understanding of the pulse market, emphasizing that the “origin declaration” on label may have a positive effect on market price.
Generalized Attracting Horseshoe in the Rössler Attractor
Authors: Murthy Karthik , Jordan Ian , Sojitra Parth , Rahman Aminur , Blackmore Denis
Published: December 2020

We show that there is a mildly nonlinear three-dimensional system of ordinary differential equations—realizable by a rather simple electronic circuit—capable of producing a generalized attracting horseshoe map. A system specifically designed to have a Poincaré section yielding the desired map is described, but not pursued due to its complexity, which makes the construction of a circuit realization exceedingly difficult. Instead, the generalized attracting horseshoe and its trapping region is obtained by using a carefully chosen Poincaré map of the Rössler attractor. Novel numerical techniques are employed to iterate the map of the trapping region to approximate the chaotic strange attractor contained in the generalized attracting horseshoe, and an electronic circuit is constructed to produce the map. Several potential applications of the idea of a generalized attracting horseshoe and a physical electronic circuit realization are proposed.
The Polarity of an Amino Acid at Position 1891 of Severe Fever with Thrombocytopenia Syndrome Virus L Protein Is Critical for the Polymerase Activity

Published: December 2020

Severe fever with thrombocytopenia syndrome virus subclone B7 shows strong plaque formation and cytopathic effect induction compared with other subclones and the parental strain YG1. Compared to YG1 and the other subclones, only B7 possesses a single substitution in the L protein at the amino acid position 1891, in which N is changed to K (N1891K). In this study, we evaluate the effects of this mutation on L protein activity via a cell-based minigenome assay. Substitutions of N with basic amino acids (K or R) enhanced polymerase activity, while substitutions with an acidic amino acid (E) decreased this activity. Mutation to other neutral amino acids showed no significant effect on activity. These results suggest that the characteristic of the amino acid at position 1891 of the L protein are critical for its function, especially with respect to the charge status. Our data indicate that this C-terminal domain of the L protein may be crucial to its functions in genome transcription and viral replication.
The Development of Electric Vehicle Charging Stations in Thailand: Policies, Players, and Key Issues (2015–2020)

Published: December 2020

This article explored the development of electric vehicle (EV) charging stations in Thailand between 2015 and 2020. This research aimed to study the main players and examine their goals, strategies, and operations in the EV charging business as well as the key issues that these charging operators have encountered in developing charging stations. The authors collected qualitative data (direct interviews with managers, video interviews, news, research articles, industry reports and press releases of EV charging operators) and used a constant comparison approach to analyze the data. The study found that after 2015, the Thai government created technology-push policies to kick-start the investment in the EV charging station business (such as subsidies for charging stations, setting a temporary selling price for electricity and building an EV charging consortium). The main players in the Thai charging business include: (1) oil and gas companies; (2) electricity state enterprises; (3) green energy companies; (4) start-ups; and (5) automotive companies. The goals of investing in the charging business for the oil and gas incumbents were to find a new growth engine and to prepare for the potential disruption in the energy sector whereas the green energy companies and start-ups wanted to capture customer bases in this promising industry. These players tended to use a partnership strategy to expand charging networks at key locations (malls, restaurants, offices). Regarding the key issues in expanding the EV charging network, the operators suggested that the high upfront investment costs, small number of EV users, and the high electricity prices (from the demand charge and usage guarantee fee) make them ‘wait-and-see’ and cautiously expand the charging network. Finally, we found that the government tried to address the constraints by setting up a national EV policy committee to accelerate EV adoption and EV charging stations in Thailand. The committee also set a fixed and reduced electricity price for charging operators.

Published: December 2020

In Pragmatics, scholars have given special attention to study the influence of leaners culture and social rules in understanding and using target language pragmatics. For this purpose, speech acts have been studied quite widely. This study investigates the speech act of responding to apology in Pakistani English, British English and Pakistani Urdu, and tries to highlight whether respondents transfer their cultural and social rules in the target language or not. The present study followed quantitative approach for data collection and analysis. A discourse completion test (DCT), consists of 12 apology response scenarios is used for data collection. The findings illustrate that English-using Pakistanis pragmatic choices are clearly influenced by their perceptions of various sociocultural and contextual variables. The English-using Pakistanis and Pakistani Urdu speakers are found using two main strategies (Acceptance, and Acknowledgment). In contrast, British English speakers tend to use Acceptance and Evasion strategies more often. Further, the findings have indicated that English-using Pakistanis and Pakistani Urdu speakers have used more Rejection strategies than their British English counterparts, though such communicative features are not salient in their ARs, and Pakistanis are surprisingly found quite clear and direct. The findings of the study may be helpful to English teachers who should be made aware that L2 learners’ pragmatic transfer is influenced by learners’ culture and social rules, and, as a result, should not be treated simply as a pragmatic ‘error’ or ‘failure’ to be corrected and criticized.

Published: December 2020

En las últimas décadas, asistimos al denominado giro espacial en las ciencias sociales. Se trata de un proceso en marcha donde la espacialidad de los fenómenos sociales adquiere gran relevancia para diferentes enfoques disciplinares. Sin embargo, como investigadores/as nos enfrentamos permanentemente al desafío de la elección de conceptos geográficos que permitan dar cuenta de nuestros objetos-sujetos de análisis. El presente texto busca compartir este dilema teórico, haciendo foco en los conceptos de territorio y lugar como posibles herramientas analíticas para el estudio de procesos productivos asociativos enmarcados en la Economía Social y Solidaria. Para ello, desarrollamos algunos aspectos del mencionado giro espacial y profundizamos en la producción del espacio desde las alternativas económicas apuntadas. Luego, proponemos la constelación de conceptos geográficos como catálogo teórico a partir del cual se toman las nociones de territorio y lugar. Así, describimos las principales dimensiones de ambos términos apoyándonos en un par de estudios de caso vinculados al ámbito rural de la provincia de Mendoza. Finalmente ensayamos algunas reflexiones y conclusiones sobre los diferentes aspectos teóricos y prácticos que intervienen en la elección de conceptos geográficos.
Reevaluating the Role of Innovation in Education
Authors: Diamantidaki Fotini , Kefalaki Margarita
Published: December 2020

Education is a social process, ‘a process of living and not a preparation for future living’ (Dewey: 1916). It requires educators to interact with other people in real time with the hope to bring out their full potential. It is grounded in collaboration, mutual respect and inclusive practices. If education is a process of living and not a preparation for it, it should then reflect what happens in life and it should emerge and evolve from any circumstances. Including the most unprecedented ones.
Menamai Sang Nama: Polemik Nama YHWH-Allah
Authors: Lilo Deflit Dujerslaim
Published: December 2020

Abstract: The focus of this paper is about the polemic that occurred around the use of the names Yahweh and God in Christianity. The name Yahweh is claimed by The Sacred Name Movement as the only name of the LORD to be believed and mentioned by believers. Therefore, the purpose of this research is to examine this view and find out whether the mention of the name of God that used in both the Bible and worship is wrong and Christianity must re-use the name Yahweh. Using qualitative methods sourced from literature studies, authors make the critical but evaluative studies by examining hermeneutically and collecting data from various sources of literature. As a result, researcher concludes that Christianity is not antipathic to the use of the name Yahweh but stating that mentioning and using the name Yahweh will affect on the salvation of someone is an absurd assumption and a logical fallacy.
 
Keywords: God, the sacred name movement, tetragrammaton, Yudaism
 
Abstrak-Fokus dari tulisan ini adalah mengenai polemik yang terjadi di seputar penggunaan nama Yahweh dan Allah dalam kekristenan. Nama Yahweh diklaim oleh kelompok Gerekan Nama Suci sebagai satu-satunya nama TUHAN yang harus diimani dan disebut oleh orang percaya. Karena itu, tujuan penelitian ini adalah untuk mengkaji pandangan tersebut dan menemukan apakah sebutan Allah yang digunakan baik di dalam Alkitab maupun ibadah adalah sebutan yang keliru dan dengan demikian kekristenan harus kembali menggunakan nama Yahweh. Menggunakan metode kualitatif yang bersumber dari studi literatur, penulis membuat kajian yang bersifat kritis namun evaluatif dengan meneliti secara hermeneutis maupun mengumpulkan data dari berbagai sumber kepustakaan. Hasilnya, peneliti menyimpulkan bahwa kekristenan tidak bersikap antipati terhadap penggunaan nama Yahweh tetapi dengan menyatakan bahwa menyebut dan menggunakan nama Yahweh akan memengaruhi keselamatan seseorang merupakan asumsi yang absurd dan cacat logika.

Published: December 2020

The article presents the results of studies of the features of photorecovery of trifunctional and tetrafunctional phosphorus-containing methacrylates with various spacers in the structure. It was found by differential scanning calorimetry that the introduction of spacers leads to a decrease in the overall thermal effect of the UV-curing process in comparison with a spacerless sample. With the help of a photocell for an E7-25 immittance meter, which is capable of recording changes in dielectric properties over time, the influence of the spacer and its structure on the degree of completion of the UV-curing process was determined. The effect of the introduced spacer on the formation of a crosslinked polymer is shown, which is manifested by different times of the induction period.

Objetivo. Estandarizar un nuevo protocolo de inmunohistoquímica para identificar Helicobacter pylori, en biopsias gástricas. Material y Métodos: el trabajo se realizó en tres fases. La primera fase hace uso de anticuerpos policlonales de conejo Anti-H. pylori como anticuerpo primario para la marcación de dicha bacteria, además de un polímero EnVision FLEX/HRP para la marcación en biopsias gástricas. En la segunda se modificó el contraste de la inmunotinción con los colorantes Hematoxilina de Harris y Eosina Y, con la finalidad de apreciar con más claridad la citomorfología del tejido gástrico a examinar y a los posibles cambios histológicos pre malignos. Por último se procedió a valorar los resultados frente a la tinción Hematoxilina y Eosina (H&E). Resultados y Discusión: Demostramos que al realizar el nuevo protocolo de inmunohistoquímica facilita la identificación de H. pylori y a su vez permite evaluar los cambios citomorfológicos en las biopsias gástricas. El establecimiento de este protocolo permitirá estudiar adecuadamente la asociación de la infección por H. pylori y los cambios histológicos pre-malignos en el tejido gástrico.

Objetivo. Comunicar el primer reporte de Klebsiella pneumoniae productora de carbapenemasas. El estudio: Diagnóstico microbiológico empleando métodos fenotípicos: sinergia del doble disco, Test de Hodge modificado, inmunocromatografia y la inactivación del carbapenémico. Hallazgos: Se confirmaron cuatro aislamientos (orinas 3 y sangre 1) de K. pneumoniae productoras de carbapenemasas que además presentaron una CMI de 4 y > = 8 para el ertapenem y > = 16 µg/mL a imipenem y meropenem. Conclusiones: los métodos fenotípicos estandarizados son de utilidad en la confirmación de carbapenemasas y con ello una alternativa para la mejor toma de opciones terapéuticas y vigilancia epidemiológica.

Objetivo. El estudio de cohortes es un diseño de tipo observacional. Este diseño solo incluye participantes que tienen el mismo riesgo de estar expuestos, para luego comparar quienes de los expuestos y no expuestos presentarán el desenlace de interés durante el mismo periodo de tiempo. La temporalidad entre la exposición y el resultado de interés en un estudio de cohorte está bien definida porque se tiene certeza de que la exposición antecede al resultado de interés. Los estudios de cohorte pueden ser prospectivos, retrospectivos o una combinación de ambos. Una de las principales ventajas es su naturaleza longitudinal, lo que permiten estimar la incidencia y el riesgo relativo como asociación de interés. Algunas variables pueden variar en el tiempo por lo que es importante, utilizar técnicas de modelamiento de datos avanzados como los modelos de efectos fijos y aleatorios.
Detección de problemas de accesibilidad en la utilización de lectores de pantalla en aplicaciones web
Authors:   , Durgam Fernando

La Accesibilidad es un factor muy importante en las aplicaciones web. Una web accesible ofrece acceso equitativo e igualdad de oportunidades a las personas con discapacidad. Es necesario garantizar el derecho a expresión, opinión, y no discriminación en el acceso a los contenidos de páginas web a todas las personas con capacidades reducidas. Esta propuesta facilita el reconocimiento automático de problemas de accesibilidad Web y ofrece soluciones a ellos, aplicando una extensión metodológica de Self Refactoring (Grigera, 2017). De esta manera y reutilizando la herramienta Kobold, se implementan procesos de detección de obstáculos en la accesibilidad para usuarios con dificultades visuales que utilizan el screen reader NVDA. Esto es posible definiendo, a partir de las interacciones de los usuarios, accessibility smell (problemas) y accessibility refactorings (soluciones) como transportaciones a las presentaciones web aplicables a esos problemas, cuya implementación tecnológica es una extensión de Kobold que ofrece Accesibilidad como servicio (SaaS – Software as a Service). Gracias a esto no se requiere tener conocimientos específicos sobre accesibilidad, sino que la herramienta se instala fácilmente en los sitios web y a medida que estos son utilizados se reportan automáticamente los problemas detectados. Pero al utilizar NVDA algunas interacciones se producen sobre representaciones de los documentos web en estructuras internas que facilitan la navegación de los elementos mediante acciones de acceso directo. Para estos casos, fue necesario desarrollar un complemento para NVDA que detecta interacciones virtuales de los usuarios y las reporta para su análisis a un componente de servidor a fin de detectar dificultades que puedan estar presentes en el buffer virtual. Con el fin de mejorar la precisión en las definiciones de los eventos que dan cuenta de los problemas de los usuarios se desarrolló un sistema y un complemento para NVDA que se utiliza en la estimación de los valores representativos de las acciones de los usuarios, con los cuales llevar adelante experimentos que permitan obtener mejores valores para los parámetros definidos en los algoritmos de detección de Accessibilty Event. Los problemas de accesibilidad, Accessibility Smell, reconocidos en estudios de casos son catalogados junto con la evaluación de los problemas de accesibilidad presente y cuya detección es posible automáticamente. Así también para las soluciones a esas dificultades denominadas Accessibility Refactorings que se definen como modificaciones a las presentaciones web, alguna de las cuales pueden aplicarse con algún grado de automatización.
Un camino fluctuante para el análisis del territorio en el devenir del espacio geográfico
Authors:   , D'Amico Gabriela Mariana
Published: December 2020

La presente tesis doctoral tiene como objetivo principal analizar el devenir espacial de la costa estuarial bonaerense desde el origen de su poblamiento hasta la actualidad, a partir de un estudio retrospectivo de los cambios en la valoración de disponibilidades territoriales existentes en distintos momentos históricos. La escasez de estudios geográficos que consideren la costa estuarial bonaerense al sur de la Región Metropolitana de Buenos Aires conduce a interrogar ¿Cuáles han sido los mecanismos de conformación de estos territorios? ¿Qué vínculos han tenido históricamente estos territorios con otros? ¿Cuáles han sido y desde dónde se vectorizaron las valoraciones de las disponibilidades territoriales costeras? ¿De qué manera han operado en las transformaciones del territorio? ¿Han quedado herencias de ello? ¿Se puede hablar de la costa estuarial bonaerense como una particularidad diferenciada de la costa estuarial metropolitana? Siguiendo este camino se planteó la siguiente hipótesis: la costa estuarial bonaerense presenta usos del suelo, marcas y herencias territoriales derivadas de distintas valoraciones del espacio costero, en función de otorgar valor a disponibilidades anfibias existentes en distintos tiempos para la reproducción social y/o económica de ciertos grupos de actores sociales. Coexisten en la actualidad espacios escasamente modificados con otros que han condensado los flujos de inversión a lo largo del tiempo. La tesis se despliega en cinco capítulos. En el primero se desarrolla la propuesta teórico metodológica a partir de la consideración de tres fluctuaciones: el territorio y el espacio geográfico, el presente y el pasado, y la dimensión anfibia que define al ámbito estuarial y sus costas desde el juego tierra-agua. El segundo capítulo transita por aproximaciones que sitúan a la zona costera en estudio inmersa en otras escalas espaciales. En el tercero se abordan recortes territoriales seleccionados desde una perspectiva diacrónica, para en el cuarto capítulo vincularlos desde una perspectiva sincrónica-diacrónica en la escala de la zona costera, incluyendo otros sectores de la zona costera no analizados en el capítulo 3. Por último, el capítulo cinco recoge las principales reflexiones de los capítulos anteriores y se proponen algunos lineamientos para futuros análisis.
