Published: August 2020

La aplicación del modelo hidrológico L-THIA ©, con apoyo en la metodología del número de la curva (CN) del Servicio de Conservación de Suelos de Estados Unidos, es empleado para transformar la precipitación total en precipitación efectiva, constituyéndose en una herramienta de gran valor para realizar estudios hidrológicos en cuencas hidrográficas, en las que no se cuenta con registros lo suficientemente extensos y confiables. Esta metodología requiere del conocimiento del tipo y uso de suelo de la cuenca en estudio, así como de registros de precipitación, en estaciones cercanas a ella. El presente estudio se aplica en la cuenca hidrográfica de los ríos Singuil y Chavarria, Tucumán, Argentina. Se cuantificó el uso y cobertura del suelo a partir del procesamiento de imágenes Landsat TM, identificando los cambios de uso y cobertura del suelo para el período 1986-2010. El procesamiento digital de la base de datos vectorial consistió en la rasterización automática con herramientas de sistema de información geográfica. Se obtuvo el valor de CN y se cuantificó la lámina de escurrimiento. La disminución de la cobertura de pastizal y su reemplazo por bosque nativo, incrementa la tasa de infiltración reduciendo el escurrimiento superficial.

Published: August 2020

La provincia de Catamarca posee un clima árido en la mayor parte de su territorio, lo cual hace indispensable el riego para la producción. En la zona central de esta provincia se encuentra uno de los sistemas de riego mediante canales más importantes de la misma, el cual es abastecido de agua por el embalse Las Pirquitas. Este sistema de riego consta de tres canales principales, dos de los cuales son los más importantes por el caudal que transportan y la longitud que poseen. El desconocimiento de las pérdidas por infiltración de estos canales es uno de los problemas en la zona, por ello se planteó la determinación de la eficiencia de conducción de estos canales. Para esta determinación se dividieron esquemáticamente los dos canales principales en trayectos y en cada uno de ellos se utilizó el método de caudal de entrada y salida. Las mediciones de caudal se realizaron con el método de sección y velocidad, para esta última se utilizó un molinete. Los resultados permitieron conocer que en general las eficiencias en los dos canales principales son aceptables, a pesar de la antigüedad de cincuenta y seis años de uno de los canales.

Authors: Kersten Michelle , Coxon Kristy , Lee Hoe , Wilson Nathan J.
Published: August 2020

Importance: Autistic adults face decreased community participation for employment, education, and social activities plus barriers to driving and transportation. However, little is known about their experiences of moving around community environments.

Objective: To explore contextual issues and experiences of independent community mobility and driving for autistic adults and to determine the modes of community mobility, regions studied, and methodologies used.

Data Sources: Seven databases were searched from 2000 to 2019. All empirical research relating to autism, community mobility, and driving for people older than age 5 yr was mapped. Studies examining experiences of community mobility and driving were selected for scoping review.

Study Selection and Data Collection: Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews methodology was used. Thirteen studies reporting specifically on autistic adults’ experiences with public transportation, driving, and pedestrian navigation of community environments were included. These studies were analyzed using concepts from the Person–Environment–Occupation–Performance Model.

Findings: Nine studies examined experiences of autistic adults. Seven studies explored proxy perspectives. Those studies examining driving primarily focused on learner driver experiences. Although most studies reported on personal and environmental factors, some studies reported on broader social communication and personal narrative factors. None used inclusive methodology involving autistic adults.

Conclusions and Relevance: A broader focus on the contextual experiences of community mobility and driving is needed to support participation of autistic adults in their communities. Linking community mobility experiences with participation outcomes and expanding research to include experienced drivers and nonurban populations is an important component of this work.

What This Article Adds: Occupational therapy interventions should address community mobility and driving skills before school transition. Autistic adults’ skill development may be affected by person factors such as motivation, anxiety, social skills, communication, and occupational performance desires. Environmental factors such as parental concerns, community safety, pedestrian environments, traffic volume, and public transportation design are important. Further research partnering with autistic adults could better inform future occupational therapy interventions for community mobility and driving.

Published: August 2020

Abstract. Radiation calibration of airborne SAR images is the basis for realizing the quantitative processing of airborne SAR images. Radiation calibration based on point targets is a general and convenient method. However, high precision is still the goal of improving the current point target SAR radiation calibration. For the key technology of high-precision radiation calibration processing for airborne SAR images, this paper uses the integral method and the peak method to calculate the point target radiation response energy, By analysing the radiation characteristics of the SAR image and comparing the methods, the sinc function model is used to fit the corrected antenna pattern. Combined with the radar power equation to solve the calibration constant, the complete point target radiation calibration method and process are established, and the different methods in the key technology are compared and analysed. The results show that the calibration method combined with the energy calculation model of the integral method and the sinc function antenna pattern correction model can achieve higher relative and absolute calibration accuracy. The optimized method can meet and exceed the requirements for radiometric calibration accuracy for high-resolution airborne SAR applications.
IMPROVED INDOOR POSITIONING USING BLE DIFFERENTIAL DISTANCE CORRECTION AND PEDESTRIAN DEAD RECKONING
Authors: Tang Y. T. , Kuo Y. T. , Liao J. K. , Chiang K. W.
Published: August 2020

Abstract. Recently, indoor positioning becomes a popular issue because of its corresponding location-aware applications. Owing to the limits of the sheltered signal of satellites in indoor environments, one of the alternative scheme is Bluetooth Low Energy (BLE) technology. BLE device broadcasts Received Signal Strength Indicator (RSSI) for distance estimation and further positioning. However, in the complex indoor environment, the reflection, fading, and multipath effect of BLE make the variable RSSI and may lead to poor quality of RSSI. In this study, the concept called Differential Distance Correction (DDC) is similar to the Differential Global Navigation Satellite System (DGNSS). This method can eliminate some residuals and further improve the results with the corrected distance. On the other hand, Pedestrian Dead Reckoning (PDR) is another common indoor positioning method. PDR can propagate the next position from the current position by the implemented of inertial sensors. Despite that, the error of inertial sensors would accumulate with time and walking distance, which position update is required for restraining the drift. Accordingly, the two indoor positioning methods have their strong and weak point. BLE-based positioning is absolute positioning, while PDR is relative positioning. This study proposes a concept that combines the two methods. The pedestrian receives the RSSI and records the information from inertial sensors simultaneously. Through the complementary of two methods, the positioning results would be improved from 29% to 66% according to different travelled distance.

Published: August 2020

Abstract. This paper presents an algorithm developed to solve a duplicity problem found during the development of a software system for BIM generation. The chosen schema for the BIM is gbXML. The Manhattan World Assumption is adopted because the objective of the system is to obtain simplified and regularized 3D models of the indoor environment to perform a thermal analysis. At the moment of writing the gbXML, some duplicity and errors were found in the polygons of both sides of walls that divide adjacent rooms. The algorithm presented in this paper was developed to detect and solve these errors. Also, this paper includes the testing and validation of the algorithm. The test is based on the application of the algorithm to six different scenarios of study: four of them are artificial scenarios developed to test the different issues detected and two of them are real cases.

Published: August 2020

Abstract. Over the decades, autonomous driving technology has attracted a lot of attention and is under rapid development. However, it still suffers from inadequate accuracy in a certain area, such as the urban area, Global Navigation Satellite System (GNSS) hostile area, due to the multipath interference or Non-Line-of-Sight (NLOS) reception. In order to realize fully autonomous applications, High Definition Maps (HD Maps) become extra assisted information for autonomous vehicles to improve road safety in recent years. Compared with the conventional navigation maps, the accuracy requirement in HD Maps, which is 20 cm in the horizontal direction and 30 cm in 3D space, is considerably higher than the conventional one. Additionally, HD Maps consist of rich and high accurate road traffic information and road elements. For the requirement of high accuracy, conducting a Mobile Laser Scanning (MLS) system is an appropriate method to collect the geospatial data accurately and efficiently. Nowadays, digital vector maps are constructed by digitalizing manually on the collected data. However, the manual process spends a lot of manpower and is not efficient and practical for a large field. Therefore, this paper proposes to automatically construct the crucial road elements, such as road edge, lane line, and centerline, to generate the HD Maps based on point clouds collected by the MMS from the surveying company. The RMSEs in the horizontal direction of the road edge, lane line, and centerline are all lower than 30 cm in 3D space.
VISUAL-BASED INTEGRATED NAVIGATION SYSTEM APPLIED TO A SIMULATION OF LUNAR MODULE LANDING
Authors: Kuo C. T. , Tien Y. T. , Chiang K. W.
Published: August 2020

Abstract. With the development of space technology, more and more lunar researches are performed by different countries. For the lunar landing mission success, the lunar landing module should equip with advanced Positioning and Orientation System (POS) for the navigation requirements. For the pinpoint landing mission formulated by NASA, a good POS with error less than 100 meters is needed in order to make the lunar module land safely at the exact destination on lunar surface. However, the existing technologies for lunar navigation, such as satellite positioning and star tracker, have poor performance for the navigation requirements. The visual-based positioning technology is an alternative way to make sure a lunar landing module reaches the destination. There are two types of visual-based positioning technology, absolute and relative navigation. The relative navigation system can provide the solution at a higher rate, but the error would accumulate over time. On the contrary, the absolute navigation could provide an initial position or updates of position and attitude for relative navigation. Thus, the integrated navigation system from those two methods can take advantage of both stand-alone systems. On the other hand, the Inertial Navigation System (INS) can help it overcome the disadvantage that the images much closer to the lunar surface are not available. This study shows an integrated navigation system that integrates a visual-based navigation system and an INS, which is implemented in a simulated lunar surface.

Published: August 2020

Abstract. This paper introduces the Phase One Aerial System 150, a next generation fully integrated fully digital aerial camera system with one single digital camera head and lens which almost matches the perfect geometry of a film camera for all airborne mapping applications. It is the first true replacement for the simplicity, geometry and efficiency established by film cameras for traditional airborne mapping. Several test flights were planned to be flown with the Phase One Aerial System 150 over the Greater Denver Area, Colorado, U.S.A. during the Winter of 2020. Two lenses are planned to be used, namely: 1) 50 mm lens for wide coverage and a geometry closest to that of a film camera which is suitable for most mapping applications, and 2) 90 mm lens which provides a higher resolution (smaller GSD) and a narrower field of view which is suitable for applications where less building lean might be required. Multiple flight altitudes are flown in order to end up with a GSD of 10 cm, and 20 cm, respectively. One dual-altitude flight was planned to characterize and calibrate the integrated system including camera in-flight calibration and camera/IMU boresight calibration. The remaining flights are planned to be used to validate system accuracy and productivity as well as the mapping product accuracy. Due to the Covid-19 pandemic and poor weather, only one full dual-altitude light has been flown. Therefore, system calibration, assessment, and validation are done using this single test flight. The remainder of the test flights intended for map production evaluation and accuracy assessment will be flown during the Spring of 2020, which results will be shared with the ISPRS audience during the congress presentations.

Authors: Nakano K. , Tanaka Y. , Suzuki H. , Hayakawa K. , Kurodai M.
Published: August 2020

Abstract. Unmanned aerial vehicles (UAVs) equipped with image sensors, which have been widely used in various fields such as construction, agriculture, and disaster management, can obtain images at the millimeter to decimeter scale. Useful tools that produce realistic surface models using 3D reconstruction software based on computer vision technologies are generally used to produce datasets from acquired images using UAVs. However, it is difficult to obtain the feature points from surfaces with limited texture, such as new asphalt or concrete, or detect the ground in areas such as forests, which are commonly concealed by vegetation. A promising method to address such issues is the use of UAV-equipped laser scanners. Recently, low and high performance products that use direct georeferencing devices integrated with laser scanners have been available. Moreover, there have been numerous reports regarding the various applications of UAVs equipped with laser scanners; however, these reports only discuss UAVs as measuring devices. Therefore, to understand the functioning of UAVs equipped with laser scanners, we investigated the theoretical accuracy of the survey grade laser scanner unit from the viewpoint of photogrammetry. We evaluated the performance of the VUX-1HA laser scanner equipped on a Skymatix X-LS1 UAV at a construction site. We presented the theoretical values obtained using the observation equations and results of the accuracy aspects of the acquired data in terms of height.

Authors: Zhao L.
Published: August 2020

Abstract. The Ziyuan-3 (ZY-3) is the first civil high-resolution optical stereoscopic mapping satellite developed by China. It was launched on January 9, 2012, and as of January 9, 2020, it has been in a continuous operation for 8 years in orbit. The direct geolocation performances of ZY-3 based on the Rational Polynomial Coefficients (RPC) model are discussed, and the monoscopic and stereoscopic geometric accuracy of ZY-3 with ground control point (GCP) have also been studied using a bundle block adjustment with the affine correction in image space. Through the analysis of 47 sets of ZY-3 stereo data in Harbin, China, it can be found that from 2012 to 2019, the ZY-3 geolocation accuracy without GCP remains stable, with an average planimetric accuracy of approximately 16.2m, an average elevation accuracy of about 7.5m. The internal accuracy of the panchromatic triplet images is better than 1.0 pixel, the planimetric accuracy and elevation accuracy of stereo triplets and and stereo pairs are better than 2.0 meters with control points. In general, the results show that the ZY-3 satellite has been in good and stable condition during in-orbit operation in the past 8 years, and the various test indicators have been able to meet the design specifications.
COMPARING THE ACCURACY OF GNSS POSITIONING VARIANTS FOR UAV BASED 3D MAP GENERATION

Published: August 2020

Abstract. GNSS stands for Global Navigation Satellite System and is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. The advantage of having access to multiple satellites is accuracy, redundancy, and availability at all the times. Though satellite systems do not often fail, if one fails GNSS receivers can pick up signals from other systems. If the line of sight is obstructed, having access to multiple satellites is also a benefit. GPS (Global Positioning System, USA), GLONASS (Global Navigation Satellite System, Russia), BeiDou (Compass, China), and some regional systems are positioning systems that are usually used. In recent years with the development of the UAVs and GNSS receivers, it is possible to manage an accurate PPK (Post Processing Kinematic) networks with a GNSS receiver mounted on a UAV to achieve the position of images principal points WGS1984 and to reduce the need for GCPs. But the most important challenge in a PPK task is, which a combination of different GNSS constellations would result in the most accurate computed position in checkpoints. For this purpose, this study focused on a PPK equipped UAV to map an open pit (Golgohar mine near Sirjan city). For the purpose, different combination of GPS, GLONASS and BeiDou used for position computed. Results are plotted and compared and found out having access to multiple constellations while doing a PPK task would bring higher accuracies in building photogrammetric models although it may cause some random error due to the higher values of noise while the number of the satellites increases.

Abstract. Remote sensing system fitted on UAV (Unmanned Aerial Vehicle) can obtain clear images and high-resolution aerial photographs. It has advantages of flexibility, convenience and ability to work full-time. However, there are some problems of UAV image such as small coverage area, large number, irregular overlap, etc. How to obtain a large regional map quickly becomes a major obstacle to UAV remote sensing application. In this paper, a new method of fast registration of UAV remote sensing images was proposed to meet the needs of practical application. This paper used Progressive Sample Consensus (PROSAC) algorithm to improve the matching accuracy by removed a large number of mismatching point pairs of remote sensing image registration based-on SURF (Speed Up Robust Feature) algorithm, and GPU (Graphic Processing Unit) was also used to accelerate the speed of improved SURF algorithm. Finally, geometric verification was used to achieve mosaic accuracy in survey area. The number of feature points obtained by using improved SURF based-on PROSAC algorithm was only 9.5% than that of SURF algorithm. Moreover, the accuracy rate of improved method was about 99.7%, while the accuracy rate of improved SURF algorithm was increased by 8% than SURF algorithm. Moreover, the improved running time of SURFGPU algorithm for UAV remote sensing image registration was a speed of around 16 times than SURF algorithm, and the image matching time had reached millisecond level. Thus, improved SURF algorithm had better matching accuracy and executing speed to meet the requirements of real-time and robustness in UAV remote sensing image registration.

Published: August 2020

Abstract. Radiometric calibration has become important pre-processing with increasing use of unmanned aerial vehicle (UAV) images in various applications. In order to convert the digital number (DN) to reflectance, vicarious radiometric calibration is widely used including relative radiometric calibration. Some UAV sensor systems can measure irradiance for precise relative radiometric calibration. However, most of UAV sensor systems cannot measure irradiance and therefore precise relative radiometric calibration is needed to produce reflectance map with vicarious calibration. In this study, an optimal image selection method is proposed to improve quality of relative radiometric calibration. The method, relative calibration by the optimal path (RCOP), uses filtered tie points acquired in geometric calibration based on selection optimal image by Dijkstra algorithm. About 100 multispectral images were acquired with a RedEdge-M camera and a fixed-wing UAV. The reflectance map was produced using RCOP and vicarious calibration using ground reference panels. A validation data was processed using irradiance for precise relative radiometric calibration. As a result, the RCOP method showed root mean square error (RMSE) of 0.03–0.10 reflectance to validation data. Therefore, the proposed method can be used to produce precise reflectance map by vicarious calibration.
INDOOR LIDAR RELOCALIZATION BASED ON DEEP LEARNING USING A 3D MODEL
Authors: Zhao H. , Acharya D. , Tomko M. , Khoshelham K.
Published: August 2020

Abstract. Indoor localization, navigation and mapping systems highly rely on the initial sensor pose information to achieve a high accuracy. Most existing indoor mapping and navigation systems cannot initialize the sensor poses automatically and consequently these systems cannot perform relocalization and recover from a pose estimation failure. For most indoor environments, a map or a 3D model is often available, and can provide useful information for relocalization. This paper presents a novel relocalization method for lidar sensors in indoor environments to estimate the initial lidar pose using a CNN pose regression network trained using a 3D model. A set of synthetic lidar frames are generated from the 3D model with known poses. Each lidar range image is a one-channel range image, used to train the CNN pose regression network from scratch to predict the initial sensor location and orientation. The CNN regression network trained by synthetic range images is used to estimate the poses of the lidar using real range images captured in the indoor environment. The results show that the proposed CNN regression network can learn from synthetic lidar data and estimate the pose of real lidar data with an accuracy of 1.9 m and 8.7 degrees.

Abstract. The increasing demand for reliable indoor navigation systems is leading the research community to investigate various approaches to obtain effective solutions usable with mobile devices. Among the recently proposed strategies, Ultra-Wide Band (UWB) positioning systems are worth to be mentioned because of their good performance in a wide range of operating conditions. However, such performance can be significantly degraded by large UWB range errors; mostly, due to non-line-of-sight (NLOS) measurements. This paper considers the integration of UWB with vision to support navigation and mapping applications. In particular, this work compares positioning results obtained with a simultaneous localization and mapping (SLAM) algorithm, exploiting a standard and a Time-of-Flight (ToF) camera, with those obtained with UWB, and then with the integration of UWB and vision. For the latter, a deep learning-based recognition approach was developed to detect UWB devices in camera frames. Such information is both introduced in the navigation algorithm and used to detect NLOS UWB measurements. The integration of this information allowed a 20% positioning error reduction in this case study.

Published: August 2020

Abstract. Imaging polarimetry can obtain two-dimensional intensity distribution information and its corresponding states of polarization from the target simultaneously. Sagnac polarization imaging interferometer is one of the typical channeled polarimetry technologies. By splitting the incident light through the triangular optical structure, the polarization information of the target is modulated into the interference fringes and can be obtained by the demodulation algorithm. The non-ideal optical elements in the system will cause reconstruction errors. This article analyses several factors that affect the measurement accuracy, including the splitting ratio of polarization beam splitter and the diffraction efficiency of the blazed grating. We derive the modified intensity formula and obtain interference patterns through numerical simulations. By calculating the modulation degree of interference fringes and reconstruction error under different non-ideal parameters, we have come to the conclusion that to meet the requirement of modulation degree > 0.5 and reconstruction error < 10%, the beam splitting ratio of the PBS should be α < 1.22. The diffraction efficiency ratio of s-polarization to p-polarization of the blazed grating should be ηs/ηp > 0.83, and the first-order diffraction efficiency should be η1 > 79%.

Abstract. For ISPRS Technical Commission I (TC I), a remarkable number of 189 submissions for the 2020 Congress edition of ISPRS Annals and ISPRS Archives was received. This included both full paper and abstract submissions from all over the world. Encouraged by the success of double blind paper reviewing in preparation of the 2016 Prague congress and the 2018 Karlsruhe symposium, also this time, TC I organized a strict peer-reviewing process. This included double-blind reviewing for full papers as well as a two-stage evaluation of abstract submissions – first stage based on the submitted abstracts (“conditional acceptance”), and second stage after submission of the respective final papers.In total, we received 69 full paper submissions and 120 abstract submissions, which indicates a nice trend towards full paper submissions compared to previous TC I events.45 full papers passed the double-blind peer-review process and were accepted for publication in the ISPRS Annals (acceptance rate 64%); usually, three or four reviews were obtained for each paper. Abstract submissions and their respective final papers were reviewed by a team of professionals. In total, 76 papers were accepted to the ISPRS Archives.The manuscripts in both the ISPRS Annals and Archives cover a broad range of topics related to remote sensing platforms, technologies, systems and related methods and reflect the current trends in algorithmic research and developments in sensing and data acquisition methods. Noteworthy is that numerous contributions were submitted to Intercommission WGs of TC I with TC II and TC IV, which underlines the increasing trend towards an integral approach to sensors, systems and methods in photogrammetry, remote sensing and mobile mapping.
Utopía distópica. La “falsa calma” de las ciudades fantasma de la Patagonia.
Authors: Covacevich Pérez Mirko
Published: August 2020

Falsa calma es una denuncia de la distopía en que devino la utopía patagónica de los hidrocarburos de mediados del siglo XX. Los mismos campamentos petroleros que en tan poco tiempo poblaron la Patagonia bajo la consigna del desarrollo, hoy día sucumben ante la falta de oportunidades. Pueblos a medio hacer, abandonados por el Estado, cuyos habitantes sobreviven a duras penas en un entorno adverso. Pero no se trata ya de la hostilidad de la naturaleza “salvaje”, que tanto retrataran las narrativas del XIX: es la propia decadencia de la civilización la que corrompe las bases de la sociedad.
Invenciones de Caliban: cultura, humanismo y posoccidentalismo en Roberto Fernández Retamar
Authors: Aguirre Aguirre Carlos
Published: August 2020

Este trabajo analiza diferentes dimensiones críticas de la escritura de Roberto Fernández Retamar. La hipótesis que nos guía es que en los textos anticoloniales del poeta cubano se intuye una lectura heterogénea y no esencialista de la cultura latinoamericana, la cual se imbrica con una elaboración del concepto-metáfora de Caliban capaz de desorganizar las dicotomías culturales de la modernidad colonial. En la primera parte constatamos cómo la particularidad de su “Caliban” consiste en su capacidad de resistir a cualquier derivación cultural y escritural unilineal, logrando discurrir en sintonía con lo que Jacques Derrida define como la différance. Después reflexionamos sobre el humanismo tejido por Fernández Retamar con el mentado tropo: un humanismo anticolonial ideado desde una relación de agresividad entre lo “propio” y lo “ajeno”. Finalmente analizamos el impacto de la noción de “posoccidentalismo” propuesta por el cubano en los principales resortes críticos del poscolonialismo latinoamericano. Concluimos cómo Caliban, en tanto símbolo, no es una autoridad de lo absoluto. Por el contrario, es una herramienta que busca deshacer los modos escriturales y epistemológicos ofrecidos por la cultura occidental, y que toma forma, dentro de la obra de Fernández Retamar, en un humanismo anticolonial y posoccidental aún en ciernes.
Vicente, autoficção de Jorge Andrade
Authors: Gontijo Rosa Carlos
Published: August 2020

Este artigo traz uma reflexão acerca da autoficção no teatro, a qual se mostra um procedimento bastante peculiar e distinto daquele verificado na narrativa. A partir da personagem Vicente, presente em três peças do dramaturgo brasileiro Jorge Andrade, percebe-se que ela, apesar de ser descrita como autobiográfica pela crítica e pelo próprio autor, carrega status de personagem autoficcional. Isto porque as características intrínsecas ao gênero dramático, especialmente a representação e a presença do ator, fazem com que os domínios da realidade e da ficção sejam encarados de maneira singular pelo leitor ou espectador.
La evolución ideológica de Rodolfo Walsh a través de las ediciones de Operación Masacre
Authors: Puente Marta , Davis Ana
Published: August 2020

El presente artículo se divide en dos secciones; en la primera, se analiza el empleo de dos géneros –originalmente ajenos a la literatura canónica– en la novela Operación Masacre (1957) del escritor argentino Rodolfo Walsh: el denominado “no ficción” y el género policial. El proyecto de denuncia a partir de su contexto de producción –Argentina tras la Revolución Libertadora (1955)– condiciona el uso de dichos géneros debido a su idoneidad para vincular ficción y realidad política. Pero la denuncia no se mantiene igual a lo largo de las distintas ediciones del libro, cuya evolución va en consonancia a otros cambios socio-políticos en el seno del país. En concreto, el acercamiento de la izquierda al peronismo genera una atracción en intelectuales que, como Walsh, ven en la doctrina de Perón un modo de resistencia política frente a las injusticias del Estado. Por ello, en la segunda parte del trabajo se examina dicha evolución en los paratextos de Operación Masacre ya que ponen de manifiesto esa aproximación de Walsh al peronismo y dan un nuevo sentido a la denuncia de su novela.

Nilkamal plastics have been successful in positioning its products well in the market. It became popular especially in South India, where consumers prefer simple living and hence had a demand for plastic furniture too.Recommendations: Nilkamal can promote its brand based on the driving factors: lightweight, weatherproof, termite-proof, and economical.Implications: The findings of the study have implications for branding, positioning decisions, brand equity measurement and marketing communications. The essential ramification of an advancing framework is the presentation toward tending to customer needs those results in extended purchaser dependability. A publicizing methodology has basic ramifications for things such as design and progression.
Constructional analogy and reanalysis in possessive applicatives
Authors: Nikolaeva Irina
Published: August 2020

Although possessors internal to an argument DP do not qualify as canonical controllers of verbal agreement, in some languages an internal possessor may be cross‑referenced on an applicative verb. The aim of the paper is to propose a historical scenario for the emergence of this pattern, following the basic insights of the constructional approach to language change. The paper argues that this pattern is a historical innovation. It emerged when the external benefactive argument was reanalysed as internal possessor, a process that has parallels in some languages with dative possessors. The change was motivated by cross‑constructional analogy, namely, formal and semantic assimilation to the class of internal possessive constructions. When constituency was reanalysed, the location of agreement remained intact creating a non‑local configuration.
Crowdfunding in urology: Canadian perspective
Authors: Di Carlo Alessia , Leveridge Michael , McGregor Thomas B.
Published: August 2020

Introduction: Crowdfunding is becoming an increasingly used resource for patients to cover costs related to medical care. These costs can be related directly to treatments or indirectly to loss of income or travel-related costs. Little is known as to the extent of which crowdfunding is used for urological disease here in Canada. This study offers a first look at the prevalence of crowdfunding for urological disease and the factors surrounding its use.

Methods: In January 2020, we queried the GoFundMe internal search engine for fundraising campaigns regarding urological ailments. Results were categorized according to the major organs of urological disease.

Results: Crowdfunding campaigns are very prevalent within several areas of urology. Prostate cancer and chronic kidney disease represent the most frequent reason for campaigns. Fundraising goals and actual funds raised for malignant disease were significantly more than for benign disease. Interestingly, there was a significant portion of crowdfunding campaigns to cover costs for non-conventional treatments and transplant tourism.

Conclusion: Crowdfunding use to help cover direct and indirect costs of medical care is becoming increasingly apparent through several facets of medicine. This study shows that this statement holds true when looking at patients with urological disease in Canada. As urologists, we need to be aware of this trend, as it highlights the often-unforeseen financial burdens experienced by our patients.
