Characteristics and Mechanisms of Marine Heatwaves in the East Asian Marginal Seas: Regional and Seasonal Differences
Authors: Choi Wonkeun , Bang Minkyoung , Joh Youngji , Ham Yoo-Geun , Kang Namyoung , Jang Chan Joo
Published: July 2022

Characteristics of marine heatwaves (MHWs) in the East Asian Marginal Seas (EAMS) were investigated using the daily Optimum Interpolation Sea Surface Temperature for 37 years (1982–2018), focusing on seasonal changes and regional differences. The summer MHWs occur 54% more frequently (2.7 events/decade) in a relatively wide area than in other seasons. The strong (up to 3.7 °C) and long-lasting (up to 38 days/event) winter MHWs are concentrated along the subpolar front (SPF) in the East/Japan Sea (EJS) where the MHWs are 20% longer (2.2 days/event) than in the Yellow and East China Seas (YECS). The summer MHWs are primarily driven by increased shortwave radiation associated with reduced cloud cover and latent cooling from the weakened wind over the western flank of developing subtropical highs. Driving mechanisms of the winter MHWs differ by region. The YECS MHWs occur mainly due to the atmospheric processes associated with weakening continental highs, while the EJS MHWs are largely driven by the northward shift of the SPF. Although large-scale atmospheric processes primarily drive the summer MHWs occurring in a wide area in the EAMS, our findings suggest that ocean processes can be major contributors to intensified MHW generation in limited areas, especially in winter.
Direction Estimation of Aerial Image Object Based on Neural Network
Authors: Zhang Hongyun , Liu Jin
Published: July 2022

Due to the inherent periodicity of the angle, the direction of the object detected by the current rotating object detection algorithm is fuzzy. In order to solve this problem, this paper proposes a rotating object direction estimation method based on a neural network, which determines the unique direction of the object by predicting the direction vector of the object. Firstly, we use the two components (sin θ, cos θ) of the direction vector and the length and width parameters of the object to express the object model. Secondly, we construct a neural network model to predict the parameters used to express the object model. However, there is a constraint that the sum of the squares of the two components of the direction vector of the object is equal to 1. Because each output element of the neural network is independent, it is difficult to learn the constrained data between such neurons. Therefore, the function transformation model is designed, and the network transformation layer is added. Finally, affine transformation is used to transform the object parameters and carry out regression calculation, so as to detect the object and determine the direction of the object at the same time. This paper uses three sets of data to carry out the experiment, which are DOTA 1.5, HRSC, and UCAS-AOD data sets. It can be seen from the experimental results that for the object with correct ground truth, the proposed method can not only locate the object but also estimate the direction of the object accurately.

Measurements in the coastal zone are carried out using various methods, including Global Navigation Satellite Systems (GNSS), hydroacoustic and optoelectronic methods. Therefore, it is necessary to develop coordinate transformation models that will enable the conversion of data from the land and marine parts to one coordinate system. The article presents selected issues related to the integration of geodetic and hydrographic data. The aim of this publication is to present the various transformation methods and their effects that relate to the data from the tombolo measurement campaign in Sopot conducted in 2018. Data obtained using GNSS Real Time Kinematic (RTK) measurements, Terrestrial Laser Scanning (TLS), the Unmanned Aerial Vehicle (UAV) and the Unmanned Surface Vehicle (USV) were transformed. On the basis of the coordinate transformation methods used, it can be concluded that the adjustment calculus method obtained the best results for the plane coordinates, while the method of P.S. Dąbrowski et al. obtained the best results for the height coordinates. The standard deviation for the difference of the modelled coordinates acquired by the method of P.S. Dąbrowski et al. with respect to the reference coordinates amounted to: 0.022 m (Northing), 0.040 m (Easting) and 0.019 m (height), respectively, while the adjustment calculus method allowed to obtain the following values: 0.009 m (Northing), 0.005 m (Easting) and 0.359 m (height). It can be assumed that a combination of these two seven-parameter transformation methods would provide the best results. In the future, a new seven-parameter transformation method should be developed based on the synthesis of these two existing methods.
Low-Elevation Target DOA Estimation Based on Multi-Scattering Center Equivalent Model
Authors: Ma Jianjun , Liu Hongwei , Ma Hui
Published: July 2022

In very-high-frequency (VHF) radar, the direction-of-arrival (DOA) estimation performance of low-angle targets tracking is strongly affected by the multipath phenomenon. Especially in the complex terrain conditions, the multipath echo comes from a region where the different scattering media make the multipath echo show the characteristics of multi-channel and uneven energy distribution. In this case, the received signal mismatches with the signal model, which leads to performance degradation and even failure of the traditional DOA algorithm. To deal with this problem, the authors propose a new signal model based on multiple scattering center. A multipath signal equivalent model is deduced and analyzed using multipath vector synthesis. Subsequently, the fitness function is established based on the equivalent model, and the target elevation angle is estimated by particle swarm optimization (PSO) algorithm. Simulation results and real data analysis show that the proposed model and algorithm can effectively improve the DOA estimation accuracy of low elevation target under complex terrain and less snapshot condition.
Calibration of D3R Weather Radar Using UAV-Hosted Target
Authors: Joshil Shashank S. , Chandrasekar Chandra V.
Published: July 2022

The accuracy of weather radar-measured products, such as reflectivity, plays a crucial factor in obtaining good quality, derived remote sensing products, such as hydrometeor classification. A slight mismatch of a few decibels in reflectivity may cause the hydrometeor classification to deviate from the actual truth. In order to obtain accurate remote-sensing measurements, calibration of weather radars should be carried out at regular intervals of time. The dual-frequency, dual-polarization, Doppler radar (D3R) is a well-established tool for measuring light rain and snow. There are various methods which are used for the calibration of weather radars, such as suspending a metallic sphere from a weather balloon or using corner reflectors on top of a tower or structure. In this work, we have shown the potential of using a UAV to suspend a calibration sphere, which is then used for calibrating the D3R radar. In this work, the advantages along with the practical aspects to be considered for calibration using UAV are discussed in detail. From the calibration results, it was observed that an offset of 2.2 dB was present in the Ku H-Pol reflectivity, Ku V-Pol was well calibrated and offsets within 2 dB were observed in the Ka H-Pol and V-Pol reflectivities.

Published: July 2022

To establish the direct climatic and environmental effect of anthropogenic aerosols in East Asia in winter under external, internal, and partial internal mixing (EM, IM and PIM) states, a well-developed regional climate–chemical model RegCCMS is used by carrying out sensitive numerical simulations. Different aerosol mixing states yield different aerosol optical and radiative properties. The regional averaged EM aerosol single scattering albedo is approximately 1.4 times that of IM. The average aerosol effective radiative forcing in the atmosphere ranges from −0.35 to +1.40 W/m2 with increasing internal mixed aerosols. Due to the absorption of black carbon aerosol, lower air temperatures are increased, which likely weakens the EAWM circulations and makes the atmospheric boundary more stable. Consequently, substantial accumulations of aerosols further appear in most regions of China. This type of interaction will be intensified when more aerosols are internally mixed. Overall, the aerosol mixing states may be important for regional air pollution and climate change assessments. The different aerosol mixing states in East Asia in winter will result in a variation from 0.04 to 0.11 K for the averaged lower air temperature anomaly and from approximately 0.45 to 2.98 μg/m3 for the aerosol loading anomaly, respectively, due to the different mixing aerosols.
Deriving River Discharge Using Remotely Sensed Water Surface Characteristics and Satellite Altimetry in the Mississippi River Basin

Published: July 2022

River discharges are critical for understanding hydrologic and ecological systems, yet in situ data are limited in many regions of the world. While approximating river discharge using satellite-derived water surface characteristics is possible, the key challenges are unknown channel bathymetry and roughness. Here, we present an application for merging mean river-reach characteristics and time-varying altimetry measurements to estimate river discharge for sites within the Mississippi River Basin (USA). This project leverages the Surface Water and Ocean Topography (SWOT) River Database (SWORD) for approximating mean river-reach widths and slopes and altimetry data from JASON-2/3 (2008–Present) and Sentinel-3A/B (2015–Present) obtained from the Hydroweb Theia virtual stations. River discharge is calculated using Manning’s Equation, with optimized parameters for surface roughness, bottom elevation, and channel shape determined using the Kling–Gupta Efficiency (KGE). The results of this study indicate the use of optimized characteristics return 87% of sites with KGE > −0.41, which indicates that the approach provides discharges that outperform using the mean discharge. The use of precipitation to approximate missing flows not observed by satellites results in 66% of sites with KGE > −0.41, while the use of TWSA results in 65% of sites with KGE > −0.41. Future research will focus on extending this application for all available sites in the United States, as well as trying to understand how climate and landscape factors (e.g., precipitation, temperature, soil moisture, landcover) relate to river and watershed characteristics.
Asymmetrical Artificial Potential Field as Framework of Nonlinear PID Loop to Control Position Tracking by Nonholonomic UAVs
Authors: Kownacki Cezary , Ambroziak Leszek
Published: July 2022

Precise position tracking plays a key role in formation flights of UAVs (unmanned aerial vehicles) or other applications based on the idea of the leader–following scheme. It decides on the integrity of a formation or increasing the position error when a UAV follows the desired flight path. This is especially difficult in the case of nonholonomic vehicles having limited possibilities of making turns, causing a lack of stability. An asymmetrical artificial potential field (AAPF) is the way to achieve the stability of position tracking by nonholonomic UAVs, but it is only a nonlinear proportional relation to feedback given by a tracking error. Therefore, there can still be a steady-state error or error overshoots. Combining an AAPF with integral and derivative terms can improve the response of control by damping overshoots and minimizing the steady-state error. Such a combination results in a regulator whose properties allow defining it as nonlinear PID. Numerical simulation confirms that integral and derivative terms together with an AAPF create a control loop that can minimize overshoots of the tracking error and the steady-state error and satisfy conditions of asymptotical stability.
Adaptive Modular Convolutional Neural Network for Image Recognition
Authors: Wu Wenbo , Pan Yun
Published: July 2022

Image recognition has long been one of the research hotspots in computer vision tasks. The development of deep learning is rapid in recent years, and convolutional neural networks usually need to be designed with fixed resources. If sufficient resources are available, the model can be scaled up to achieve higher accuracy, for example, VggNet, ResNet, GoogLeNet, etc. Although the accuracy of large-scale models has been improved, the following problems will occur with the expansion of model scale: (1) There may be over-fitting; (2) increasing model parameters; (3) slow model convergence. This paper proposes a design method for a modular convolutional neural network model which solves the problem of over-fitting and large model parameters by connecting multiple modules in parallel. Moreover, each module contains several submodules (three submodules in this paper) and fuses the features extracted from the submodules. The model convergence can be accelerated by using the fused features (the fused features contain more image information). In this study, we add a gate unit based on the attention mechanism to the model, which aims to optimize the structure of the model (select the optimal number of modules), allowing the model to select an optimum network structure by learning and dynamically reducing FLOPs (floating-point operations per second) of the model. Compared to VggNet, ResNet, and GoogLeNet, the structure of the model proposed in this paper is simple and the parameters are small. The proposed model achieves good results in the Kaggle datasets Cats-vs.-Dogs (99.3%), 10-Monkey Species (99.26%), and Birds-400 (99.13%).

Published: July 2022

Virtual reality (VR) systems are becoming increasingly attractive as joint kinematics monitoring systems during rehabilitation. This study aimed to evaluate the accuracy of the Oculus Quest 2 in measuring translational and rotational displacements. As the Oculus Quest 2 was chosen for future applications in shoulder rehabilitation, the translation range (minimum: ~200 mm, maximum: ~700 mm) corresponded to the forearm length of the 5th percentile female and the upper limb length of the 95th percentile male. The controller was moved on two structures designed to allow different translational displacements and rotations in the range 0–180°, to cover the range of motion of the upper limb. The controller measures were compared with those of a Qualisys optical capture system. The results showed a mean absolute error of 13.52 ± 6.57 mm at a distance of 500 mm from the head-mounted display along the x-direction. The maximum mean absolute error for rotational displacements was found to be 1.11 ± 0.37° for a rotation of 40° around the z-axis. Oculus Quest 2 is a promising VR tool for monitoring shoulder kinematics during rehabilitation. The inside-out movement tracking makes Oculus Quest 2 a viable alternative to traditional motion analysis systems.
College Students’ Political Attitudes Affect Negative Stereotypes about Social Groups
Authors: Beyer Sylvia
Published: July 2022

This study examined the relations between political attitudes and negative stereotypes in undergraduates by employing 4 measures of stereotypes: modern sexism, modern racism, feelings about 20 social groups, and ratings of the intelligence of these social groups. It was hypothesized that conservatives and Republicans alike would show more evidence of negative stereotypes than liberals and Democrats, especially for disadvantaged social groups. The study revealed that, indeed, Republicans showed stronger evidence of negative stereotypes but that Democrats also harbor some biases. Importantly, the social groups for whom Democrats and Republicans show negative stereotypes differed greatly. Republicans had considerably more negative stereotypes against racial and religious minorities, and particularly against individuals who do not identify with the cis-gender, heterosexual norm. Thus, the targets of Republicans’ stereotypes were groups that have traditionally been subjected to discrimination. Democrats, on the other hand, held stronger negative stereotypes against groups that are more politically powerful, such as Caucasians and Christians.

Published: July 2022

This paper seeks to contribute to a better understanding of cultural sustainability in mountain regions by offering perspectives for sustainable governance at the intersection of intangible cultural heritage preservation and local tourism development. For this purpose, the influence of tourism on intangible cultural heritage was studied in the context of the practice of transhumance, an ancient form of pastoralism. This paper focuses on the case of South Tyrol, Italy, a touristically highly developed region where cross-border transhumance was granted intangible cultural heritage status by UNESCO in 2019. Adopting a qualitative approach, 13 interviews were conducted with cattle and sheep farmers, cultural practitioners, and experts as well as tourism representatives. Highlighting the benefits of including culture in the discussion about sustainability, the paper seeks to inform local governance measures for enhanced cultural heritage preservation and sustainable tourism.
Efficient Sandstorm Image Color Correction Using Rank-Based Singular Value Recombination
Authors: Lee Hosang
Published: July 2022

Sandstorm images have a color cast that is reddish or yellowish due to the attenuation of the color channel. When light propagates through sand particles, it is scattered. Additionally, if some sand particles have a certain color, the obtained image in this circumstance experiences a color shift because some color channels are attenuated. Therefore, sandstorm images have a symmetrically distributed color cast throughout the image. There have been many studies aiming to enhance sandstorm images. In many studies, to enhance color-casted images, researchers have used the various methods as with gamma correction. However, artificial color shift occurs in an enhanced image because these methods do not reflect the image’s adaptive feature. This paper proposes a sandstorm image enhancement method using singular value recombination based on rank. The singular value of an image reflects the image’s characteristics adaptively, and improved images using the singular values have no artificial color because the balanced image eliminates the degraded color cast. Because the balanced image has hazy or dusty features, the singular value ratio can be used to enhance the image. The enhanced images produced using the proposed method are superior compared to state-of-the-art methods, objectively and subjectively.

Published: July 2022

We consider classical axially symmetric states of relativistic hydrogenic ions under collinear electric and magnetic fields of arbitrary strengths. For such Rydberg states, we study the role of relativistic effects. Our analytical results demonstrate that the primary outcome of the allowance for the relativism is an increase in the critical value of the electric field at which the ionization occurs.
Advances in Genes-Encoding Transporters for Cadmium Uptake, Translocation, and Accumulation in Plants
Authors: Tao Jingyu , Lu Lingli
Published: July 2022

Cadmium (Cd) is a heavy metal that is highly toxic for plants, animals, and human beings. A better understanding of the mechanisms involved in Cd accumulation in plants is beneficial for developing strategies for either the remediation of Cd-polluted soils using hyperaccumulator plants or preventing excess Cd accumulation in the edible parts of crops and vegetables. As a ubiquitous heavy metal, the transport of Cd in plant cells is suggested to be mediated by transporters for essential elements such as Ca, Zn, K, and Mn. Identification of the genes encoding Cd transporters is important for understanding the mechanisms underlying Cd uptake, translocation, and accumulation in either crop or hyperaccumulator plants. Recent studies have shown that the transporters that mediate the uptake, transport, and accumulation of Cd in plants mainly include members of the natural resistance-associated macrophage protein (Nramp), heavy metal-transporting ATPase (HMA), zinc and iron regulated transporter protein (ZIP), ATP-binding cassette (ABC), and yellow stripe-like (YSL) families. Here, we review the latest advances in the research of these Cd transporters and lay the foundation for a systematic understanding underlying the molecular mechanisms of Cd uptake, transport, and accumulation in plants.

Published: July 2022

Assessing and modeling the changes in land use and land cover (LULC) patterns and associated ecosystem service values (ESV) has become an important global agenda for formulating sustainable land management policies. Taking the coastal region of Bangladesh (CRB) as a case study, we utilized remote sensing and GIS techniques to analyze Landsat data of 1999 and 2019 to estimate the effect of LULC changes on the ESVs. The LULC classification, ESV quantification, and spatial variations were performed by semi-automated classification, per-unit value transfer, and spatial autocorrelation techniques, respectively. First, between 1999 and 2019, LULC altered dramatically (agricultural land and coastal wetlands decreased, while all other LULC types increased). Second, the total ESV decreased by 1.87%, which was mostly attributed to a 70% growth in both rural settlement and aquaculture/saltpan, and a 30% decline in both agricultural land and wetlands. Third, significant spatial correlation and moderately high spatial clustering were observed, which consisted mostly of mangrove forests, waterbodies, and wetland zones. Both high-high and low-low values increased, but spatial outliers remained unchanged. Conserving agricultural land should be prioritized in future land use plans of CRB to meet the ever-increasing food demands, control natural land conversion, and make land use sustainable.
Test of a Screw-Style Fish Lift for Introducing Migratory Fish into a Selective Fish Passage Device
Authors: Zielinski Daniel P. , Miehls Scott , Lewandoski Sean
Published: July 2022

Barriers are an effective mechanism for managing invasive species, such as sea lamprey in the Laurentian Great Lakes but are detrimental because they limit the migration of desirable, native species. Fish passage technologies that selectively pass desirable species while blocking undesirable species are needed. Optical sorting tools, combined with newly developed computer learning algorithms, could be used to identify invasive species from high-resolution imagery and potentially isolate them from an assortment of the Great Lakes fishes. Many existing barriers lack fishways, and optical sorting may require fish to be dewatered for image capture. The Archimedes screw, a device originating from 234 BCE, offers the potential to continuously lift fish and water over low-head barriers or into an optical sorting device. To test the efficacy of an Archimedes screw and fish lifting to capture and pass Great Lakes fishes, we built a field-scale prototype and installed it at the Cheboygan Dam, Michigan in the USA in 2021. The fish lift safely transported 704 fish (688 of which were suckers (Catostomidae)) in 11 days. The passage of the suckers through the fish lift increased with the water temperature and attraction flow. There were no observed injuries in the transported fish or mortalities in a subset of suckers held post-transport.

Sorbents based on Fe(OH)3 and aluminum oxide are widely used in oceanology for the recovery of cosmogenic radionuclides 7Be, 32Si, 32P, and 33P from the seawater. It is also possible to use them for the recovery of the natural radionuclides 210Pb, 234Th. A comparative study of the sorbents based on Fe(OH)3 and acrylic fiber obtained through various impregnation methods was carried out, and their comparison with granulated aluminum oxide. The possibility of extracting trace amounts of phosphorus and beryllium under laboratory and field conditions with these sorbents was studied. The sorption of 7Be, 210Pb, and 234Th on the natural content by the two-column method was investigated. It is shown that fiber samples obtained by oxidation with sodium ferrate and the “classical” method have the highest sorption characteristics.

This case report was prepared to provide information about cystic echinococcosis detected in a twelve years old domestic cat during experimental laparotomy. In the anamnesis, there was a complaint of progressive abdominal swelling. As a result of clinical and radiological examinations, unknown intraabdominal formations were detected. At laparotomy, multiple cysts were detected on the right and left kidneys. Molecular analysis revealed that these cystic structures are larval forms of Echinococcus granulosus. The cysts are often found in the liver and lungs but they can arise less commonly in the brain, kidneys, muscle, bone and heart. Renal cystic echinococcosis is rare and this note describes it, confirmed by molecular analysis in a domestic cat. For this reason, it is thought that this note will contribute to the literature.

The use of unmanned aerial vehicles (UAV) systems has increased in recent years. Therefore,studies on UAVs have increased today. In this direction, the production of UAV systems with domestic resources has gained importance. In this study, it is desired to develop a domestic and national flight control card and software. In the flight control board designed for the UAV, it is aimed to keep the vehicle in balance in the air. Accurate measurement of platform orientation plays an important role in many applications such as aerospace, robotics, navigation, marine, machine interaction [1]. Inertial Measurement Unit (IMU) sensor was used to accurately measure the orientation of the UAV. IMU sensor is widely used in UAVs due to its light weight and low energy consumption. In this direction, the need for a filter has emerged in the IMU sensor, which is used to accurately measure the orientation of the unmanned aerial vehicle. In this study, a complementary filter was applied on the IMU sensor. Thanks to this filter, it has been observed that the accuracy of the data received from the IMU sensor has increased. Based on the data obtained, a Proportional Integral Derivative (PID) algorithm was developed, and the vehicle was kept in balance. In this study, ARMCortex-M4 based STM32F407VG microcontroller and MPU6050 as IMU sensor were used. Keil-uVision5 compiler is preferred for software. As a result, high accuracy in the orientation detection of unmanned aerial vehicles was obtained by applying a complementary filter on the IMU sensor.

Since the malaria outbreak in 2011, the breeding place of Anopheles in Bangsring Village on Banyuwangi District has been monitored by District Public Health Office as part of a vector surveillance program. Morphological identification is still a standard tool to observe Anopheles occurrence and diversity, but the presence of cryptic species made it unreliable. In this study, a molecular approach called DNA barcoding technique was used to assist the morphology-based techniques to identify Anopheles species found in Bangsring. The internal transcribed spacer 2 (ITS2) sequence was used as molecular marker. Based on the morphological features, we were able to identify Anopheles (An.) vagus, An. subpictus, An. sundaicus and An. aconitus. ITS2 sequences from the four identified species were then analyzed simultaneously with eighteen reference sequences from NCBI which had a high similarity of 98-100%. The NJ phylogenetic tree formed three major clades, where the two clades as monophyletic clades were An. vagus and An. aconitus. Another clade was formed as polyphyletic clade containing An. subpictus and An. sundaicus. Although An. subpictus and An. sundaicus were placed in the same clade, seven nucleotide differences were observed in their ITS2 sequence. The intra-specific variation of those two species was 0.08 and 0.49%, respectively, while the interspecific variation was 1.39%. Interspecific variation which was higher than the mean intra-specific variation might indicate that An. sundaicus and An. subpictus were a distantly species. However, the value of interspecific variation lower than 3% might also indicate that those species were classified as a complex species. All ITS2 sequences from morphologically identified species had similar results with molecular-based techniques. This result showed that molecular identification using the ITS2 sequence was reliable in supporting morphological identification among closely related anopheline mosquitoes and gave further information about their evolutionary divergence.

RESUMO

A platinosomose é uma importante enfermidade hepatobiliar parasitária que acomete felinos, sendo eles de vida livre ou semi domiciliados. O agente etiológico é o trematódeo Platynosomum spp. E a doença é popularmente conhecida como “envenenamento por lagartixa”. As manifestações clínicas da platinosomose são inespecíficas assim como é incomum a observação de lesões hepáticas, o que dificulta o diagnóstico. Felinos possuem o hábito de caça e ao ingerir esses pequenos invertebrados, podem dar continuidade ao ciclo da platinosomose, uma vez que esses animais são os hospedeiros definitivos deste parasito. Esse trematódeo se aloja com frequência no trato biliar dos gatos, causando lesões e possível obstrução do ducto biliar. O grau de comprometimento das lesões hepáticas está na dependência tanto da imunidade, quanto da carga parasitária do animal. O diagnóstico de eleição é o exame parasitológico de fezes, embora ainda seja considerado pouco sensível, sendo relevante a utilização de outras ferramentas diagnósticas. O exame ultrassonográfico permite a observação de alterações hepáticas e até mesmo do próprio parasito no interior do ducto biliar, contribuindo para elucidação dessa enfermidade. Foi atendido no Hospital Veterinário “Luiz Quintiliano de Oliveira”, um felino com histórico de icterícia, e ao exame clínico observou-se escore corporal magro e desidratação em 8%. Após avaliação clínica do animal, o mesmo foi encaminhado para o setor de Diagnóstico por Imagem para avaliação ultrassonográfica abdominal, durante o exame visibilizou-se aumento das dimensões hepáticas, edema de parede em vesícula biliar e a presença pequena de estrutura filiforme, hiperecogênica, em seu interior.

El presente proyecto de investigación surgió como expresión de una inquietud promovida por la carencia de estudios sistemáticos que aborden la sociedad argentina alrededor de los años '20. Si bien desde la década del '60 se han producido avances en lo relativo al período 1916-1930—tanto en el campo de la Historia como desde la perspectiva de otras ciencias sociales— resulta evidente que resta mucho por hacer.
La cuestión de la identidad política de los colonos santafesinos: 1880 -1898. Estudio de algunas experiencias
Authors: Bonaudo Marta , Cragnolino Silvia , Sonzogni Élida
Published: July 2022

El '80 significa para la realidad argentina la consolidación de un poder centralizado, producto de la reestructuración de la alianza intero­ligárquica que construye el Estado Nacional. Detrás de la propuesta de "paz y administración" de Roca se genera una profunda rediscusión de las relaciones entre el Estado y la sociedad, en donde esferas tradicional­mente controladas por la segunda, resultan progresivamente incorpora­das al control del Estado: así el Estado monopoliza la educación ele­mental; seculariza episodios importantes de la vida privada, como el matrimonio y la muerte, reafirma la calidad y alcances del "patronato" so­bre la Iglesia Católica. Las leyes laicas van acompañadas por una opi­nión pública reactivada a través de las manifestaciones periodísticas o desde el ensayo, pero también de movilizaciones, mitines, marchas y una dinámica presencia en los debates parlamentarios.
