Authors: Yue Wei , Jiang Li , Yang Xiubin , Gao Suining , Xie Yunqiang , Xu Tingting
Published: March 2022

Polarization and infrared imaging technology have unique advantages for various applications ranging from biology to ocean remote sensing. However, conventional combined polarization camera and infrared camera have limitations because they are constrained to single-band imaging systems with rotating polarizers and cascaded optics. Therefore, we propose a common-aperture mode based on multi-band infrared guided polarization imaging system (IGPIS) in this paper, which consists of infrared wide-area sensing and polarization features acquisition for accurate detection of ship targets. The IGPIS can provide images in visible polarization (0.45–0.76 μm), near-infrared polarization (0.76–0.9 μm), and long-wave infrared (8–12 μm) bands. Satellite attitude parameters and camera optical parameters are accurately calculated by establishing a dynamic imaging model for guidance imaging. We illustrate the imaging principle, sensors specifications and imaging performance analysis and the experimental results show that the MTF is 0.24 for visible and near-infrared, and 0.13 for long-wave infrared. The obtained multi-band images have an average gradient of 12.77 after accurate fusion. These results provide theoretical guidance for the design of common-aperture cameras in remote sensing imaging field.
A Comprehensive Evaluation of Gridded L-, C-, and X-Band Microwave Soil Moisture Product over the CZO in the Central Ganga Plains, India
Authors: Dash Saroj Kumar , Sinha Rajiv
Published: March 2022

Recent developments in passive microwave remote sensing have provided an effective tool for monitoring global soil moisture (SM) observations on a spatiotemporal basis, filling the gap of uneven in-situ measurement distribution. In this paper, four passive microwave SM products from three bands (L, C, and X) are evaluated using in-situ observations, over a dry–wet cycle agricultural (mostly paddy/wheat cycle crops) critical zone observatory (CZO) in the Central Ganga basin, India. The L-band and C/X-band information from Soil Moisture Active Passive (SMAP) Passive Enhanced Level 3 (SMAP-L3) and Advanced Microwave Scanning Radiometer 2 (AMSR2), respectively, was selected for the evaluation. The AMSR2 SM products used here were derived using the Land Parameter Retrieval Model (LPRM) algorithm. Spatially averaged observations from 20 in-situ distributed locations were initially calibrated with a single and continuous monitoring station to obtain long-term ground-based data. Furthermore, several statistical metrices along with the triple collocation (TC) error model were used to evaluate the overall accuracy and random error variance of the remote sensing products. The results indicated an overall superior performance of SMAP-L3 with a slight dry bias (−0.040 m3·m−3) and a correlation of 0.712 with in-situ observations. This also met the accuracy requirement (0.04 m3·m−3) during most seasons with a modest accuracy (0.059 m3·m−3) for the entire experimental period. Among the LPRM datasets, C1 and C2 products behaved similarly (R = 0.621) with a ubRMSE of 0.068 and 0.081, respectively. The X-band product showed a relatively poor performance compared to the other LPRM products. Seasonal performance analysis revealed a higher correlation for all the satellite SM products during monsoon season, indicating a strong seasonality of precipitation. The TC analysis indicated the lowest error variance (0.02 ± 0.003 m3·m−3) for the SMAP-L3. In the end, we introduced Spearman’s rank correlation to assess the dynamic response of SM observations to climatic and vegetation parameters.

Authors: Xin Zhanhua , Kong Shihan , Wu Yuquan , Zhan Gan , Yu Junzhi
Published: March 2022

Obtaining a stable video sequence for cameras on surface vehicles is always a challenging problem due to the severe disturbances in heavy sea environments. Aiming at this problem, this paper proposes a novel hierarchical stabilization method based on real-time sea–sky-line detection. More specifically, a hierarchical image stabilization control method that combines mechanical image stabilization with electronic image stabilization is adopted. With respect to the mechanical image stabilization method, a gimbal with three degrees of freedom (DOFs) and with a robust controller is utilized for the primary motion compensation. In addition, the electronic image stabilization method based on sea–sky-line detection in video sequences accomplishes motion estimation and compensation. The Canny algorithm and Hough transform are utilized to detect the sea–sky line. Noticeably, an image-clipping strategy based on prior information is implemented to ensure real-time performance, which can effectively improve the processing speed and reduce the equipment performance requirements. The experimental results indicate that the proposed method for mechanical and electronic stabilization can reduce the vibration by 74.2% and 42.1%, respectively.

Published: March 2022

In this study, an inertial measurement unit (IMU) sensor module and software algorithm were developed to identify anomalous kicks that should not be given scores in Taekwondo competitions. The IMU sensor module was manufactured with dimensions of 3 cm × 3 cm × 1.5 cm and consists of a high-g sensor for high acceleration measurement, a 9-DOF sensor, and a Wi-Fi module for wireless communication. In the experiment, anomalous kicks and normal kicks were collected by the IMU sensor module, and an AI model was trained. The anomalous kick determination accuracy of the trained AI model was found to be 97.5%. In addition, in order to check whether the strength of a blow can be distinguished using the IMU sensor module, an impact test was performed with a pendulum under the same test conditions as the impact sensor installed in the impact test setup, and the correlation coefficient was 0.99. This study is expected to contribute to improving scoring reliability by suggesting the possibility of discriminating anomalous kicks, which were difficult to judge in Taekwondo competitions, through the analysis of Taekwondo kicks using inertial data and impulses.
Toward Exploiting Second-Order Feature Statistics for Arbitrary Image Style Transfer
Authors: Choi Hyun-Chul
Published: March 2022

Generating images of artistic style from input images, also known as image style transfer, has been improved in the quality of output style and the speed of image generation since deep neural networks have been applied in the field of computer vision research. However, the previous approaches used feature alignment techniques that were too simple in their transform layer to cover the characteristics of style features of images. In addition, they used an inconsistent combination of transform layers and loss functions in the training phase to embed arbitrary styles in a decoder network. To overcome these shortcomings, the second-order statistics of the encoded features are exploited to build an optimal arbitrary image style transfer technique. First, a new correlation-aware loss and a correlation-aware feature alignment technique are proposed. Using this consistent combination of loss and feature alignment methods strongly matches the second-order statistics of content features to those of the target-style features and, accordingly, the style capacity of the decoder network is increased. Secondly, a new component-wise style controlling method is proposed. This method can generate various styles from one or several style images by using style-specific components from second-order feature statistics. We experimentally prove that the proposed method achieves improvements in both the style capacity of the decoder network and the style variety without losing the ability of real-time processing (less than 200 ms) on Graphics Processing Unit (GPU) devices.

Authors: Kurg Kristiina , Planken Anu , Kurg Reet
Published: March 2022

Background: Malignant melanoma is the most serious type of skin cancer with the highest mortality rate. Extracellular vesicles (EVs) have potential as new tumor markers that could be used as diagnostic and prognostic markers for early detection of melanoma. Methods: EVs were purified from the blood serum of melanoma patients using two methods—ultracentrifugation and PEG precipitation—and analyzed by mass spectrometry and immunoblot. Results: We identified a total of 585 unique proteins; 334 proteins were detected in PEG-precipitated samples and 515 in UC-purified EVs. EVs purified from patients varied in their size and concentration in different individuals. EVs obtained from stage II and III patients were, on average, smaller and more abundant than others. Detailed analysis of three potential biomarkers—SERPINA3, LGALS3BP, and gelsolin—revealed that the expression of SERPINA3 and LGALS3BP was higher in melanoma patients than healthy controls, while gelsolin exhibited higher expression in healthy controls. Conclusion: We suggest that all three proteins might have potential to be used as biomarkers, but a number of issues, such as purification of EVs, standardization, and validation of methods suitable for everyday clinical settings, still need to be addressed.
User Acceptance of Hotel Service Robots Using the Quantitative Kano Model
Authors: Xie Muzi , Kim Hong-bumm
Published: March 2022

With today’s rapid technological developments, many have applied artificial intelligence and robot technology to the tourism and hotel industries, with hotel service robots (HSRs) being gradually developed. At present, more technology development companies have focused their attention on improving HSRs’ different attributes to improve their acceptance by users, thereby enhancing market competitiveness and improving customer loyalty. Understanding consumer acceptance of HSRs is important. Based on a literature review of the user’s acceptance of HSR attributes and HSRs’ current development status, some factors and attributes were extracted. For the questionnaire’s design and data extraction, the quantitative Kano model was used. The data obtained were compiled and analyzed using Microsoft Excel and SPSS. This study aims to (1) qualitatively apply the perceived value theory to develop specific HSR attributes and (2) quantitatively examine these attributes concerning public acceptance. By integrating the Kano model with the perceived value theory, this study provides empirical evidence of a nonlinear relationship between HSRs’ perceived value and user acceptance by exploring various attributes affecting the user’s acceptance of HSRs and the degree of change brought by the different attributes. The research result reveals the multidimensional impacts of perceived value, prompting users to embrace newer HSR technologies.
Research on the Evaluation Mechanism of the Black Soldier Fly Biological System on Campus
Authors: Yang Ming-Ling
Published: March 2022

Lower birth rates and spoiling have caused students to become picky eaters, leading to campus food waste. In this study, 29 evaluation indicators for a black soldier fly biological system were established through a literature review and expert interviews. The indicators were divided into three dimensions, namely spatial composition, system and equipment, and environmental education. The 11 indicators with the highest expert consensus were identified through the fuzzy Delphi method and used as the primary indicators for evaluating the role of the black soldier fly biological system in promotion. The top 11 indicators with the highest scores mostly comprised indicators of the system and equipment dimension followed by those of the spatial composition and environmental education dimensions. However, among the indicators of the three dimensions, those of the “spatial composition” dimension obtained the highest scores. The literature review indicated that the theories related to knowledge, behavior, and attitude toward the environment should be applied to consciously motivate students to reduce food waste through explicit actions. The integration of the aforementioned system with experiential agricultural education can reduce campus food waste. Participatory learning increases the willingness of students to improve appropriate environmental attitudes and healthy diets on the basis of promoting environmental sustainability.
Are Global Environmental Uncertainties Inevitable? Measuring Desertification for the SDGs
Authors: Grainger Alan
Published: March 2022

Continuing uncertainty about the present magnitudes of global environmental change phenomena limits scientific understanding of human impacts on Planet Earth, and the quality of scientific advice to policy makers on how to tackle these phenomena. Yet why global environmental uncertainties are so great, why they persist, how their magnitudes differ from one phenomenon to another, and whether they can be reduced is poorly understood. To address these questions, a new tool, the Uncertainty Assessment Framework (UAF), is proposed that builds on previous research by dividing sources of environmental uncertainty into categories linked to features inherent in phenomena, and insufficient capacity to conceptualize and measure phenomena. Applying the UAF shows that, based on its scale, complexity, areal variability and turnover time, desertification is one of the most inherently uncertain global environmental change phenomena. Present uncertainty about desertification is also very high and persistent: the Uncertainty Score of a time series of five estimates of the global extent of desertification shows limited change and has a mean of 6.8, on a scale from 0 to 8, based on the presence of four conceptualization uncertainties (terminological difficulties, underspecification, understructuralization and using proxies) and four measurement uncertainties (random errors, systemic errors, scalar deficiencies and using subjective judgment). This suggests that realization of the Land Degradation Neutrality (LDN) Target 15.3 of the UN Sustainable Development Goal (SDG) 15 (“Life on Land”) will be difficult to monitor in dry areas. None of the estimates in the time series has an Uncertainty Score of 2 when, according to the UAF, evaluation by statistical methods alone would be appropriate. This supports claims that statistical methods have limitations for evaluating very uncertain phenomena. Global environmental uncertainties could be reduced by devising better rules for constructing global environmental information which integrate conceptualization and measurement. A set of seven rules derived from the UAF is applied here to show how to measure desertification, demonstrating that uncertainty about it is not inevitable. Recent review articles have advocated using ‘big data’ to fill national data gaps in monitoring LDN and other SDG 15 targets, but an evaluation of a sample of three exemplar studies using the UAF still gives a mean Uncertainty Score of 4.7, so this approach will not be straightforward.

Published: March 2022

Anionic surfactants (AS) are becoming a major emerging contaminant of waters due to their widespread use in household and industrial products. The standard chloroform method for analysis of AS in water relies on chloroform extraction of a methylene blue active substance (MBAS), which contains ion pairs between methylene blue (MB) molecules (positively charged) and AS. Due to the poor extractability of chloroform, the procedure is complicated, time-consuming, and subject to anionic interferences. A mixture of methyl isobutyl ketone (MIBK)–1,2-dichloroethane (DCE) at a 3:1 ratio of MIBK:DCE proved to be a robust solvent for AS extraction for a wide range of samples under various chemical conditions. The objectives of this research were to set the washing protocol to eliminate the anionic interferences in the MIBK-DCE extraction and to develop a new simplified analytical method for AS analysis using the MIBK-DCE (3:1) extractant. The suitability of the proposed MIBK-DCE method was validated based on quality control and assurance criteria, such as selectivity, accuracy, precision, method detection limit (MDL), limit of quantification (LOQ), and sensitivity. Various water samples, such as freshwater, wastewater, and seawater, were used for the method development and validation. Interferences by inorganic and organic anions were evident in the reference chloroform method but were eliminated in the MIBK-DCE procedure with a two-step process that consisted of washing with a carbonate/bicarbonate solution at pH 9.2 and a mixture of silver sulfate (Ag2SO4) and potassium alum (AlK(SO4)2). The simplified MIBK-DCE method for sodium dodecyl sulfate (SDS) analysis consisted of (i) sample pre-treatment, (ii) MIBK-DCE extraction, (iii) washing and filtration, and (iv) absorbance measurement. The MIBK-DCE method was accurate, precise, selective, and sensitive for AS analysis and showed MDL of 0.0001 mg/L, LOQ of 0.0005 mg/L, relative standard deviation (RSD) of 0.1%, and recovery of 99.0%. All these criteria were superior to those of the chloroform method. Sensitivity analysis showed highly significant correlations in AS analyses between the MIBK-DCE and chloroform methods for domestic wastewater, industrial wastewater, and seawater. The MIBK-DCE method is simple, rapid, robust, reproducible, and convenient, when compared to the chloroform method. Results demonstrate that the simplified MIBK-DCE method can be employed for AS analysis in a wide range of environmental waters including seawater.
Does Globalization Encourage Female Employment? A Cross-Country Panel Study
Authors: Hossain Asrifa , Ghimire Shankar , Valeva Anna , Harriger-Lin Jessica
Published: March 2022

The objective of the paper is to examine whether female participation in the labor force (FPLF) is influenced by a country’s participation in international markets through foreign direct investment (FDI)—a proxy for globalization. We obtained a panel dataset from the World Development Indicators database for 99 countries from 2001 to 2018, and used the system generalized method of moments (system GMM) to estimate a dynamic panel model with appropriate specification tests. The results show that FDI encourages FPLF to some extent, but the positive effects are more robust for low- and middle-income countries than high-income countries. We also found that results are sensitive to extreme outlier observations in the explanatory factor FDI. These results have important policy implications for low- and middle-income countries; they recommend a focus on sectors that generate higher FDI, as these sectors stand to yield the greatest benefits with regards to female labor force participation.

Authors: Ha Gi Won , Kim Jong Hun , Kim Suhn Hee
Published: March 2022

Purpose: Renin-angiotensin system (RAS) is involved in the pathophysiology of colonic inflammation. The aim of this study was to investigate whether small angiotensins (Angs) peptides play a role in the regulation of colonic motility and their roles are modulated in colitis.Methods: Experimental colitis was induced by an intake of 5% dextran sulfate sodium (DSS) dissolved in tap water for 7 days in Sprague-Dawley rats. After sacrifice, plasma hormone concentrations and messenger RNAs (mRNAs) for RAS were measured. Functional analysis of colonic motility in response to Angs peptides was performed using Taenia coli.Results: DSS-treated colon showed an increased necrosis with massive infiltration of inflammatory cells. The mRNA level of colonic angiotensin II receptor type 2 (AT2R) in DSS-treated rats was higher than that in control rats whereas the mRNA levels of angiotensin II converting enzyme (ACE), ACE2, AT1R, AT4R, and Mars receptor were not different from those in control rats. Ang III, Ang IV, and Ang-(1-9) (1, 3 μM) increased the frequency of basal colonic motility. Ang-(1-7) did not cause any significant changes in frequency and amplitude of basal motility. The order of potency for an increased frequency of basal motility seems to be Ang II>>Ang IV>Ang III=Ang-(1-9). The increased frequency of basal motility by Ang-(1-9) but not Ang IV was significantly enhanced in DSS-treated rat colon.Conclusion: In conclusion, these data suggest that small Angs peptides are partly involved in the pathophysiological regulation of colonic motility in experimental colitis.

Authors: Ivanov V. , Nurmukhametov R.
Published: March 2022

Corporate governance issues in the context of the ongoing process of digitalization of the economy and the implementation of the ESG agenda are increasingly attracting the attention of both business owners, management, and all interested parties (shareholders, customers, suppliers, employees, investors, communities). One of the important elements of corporate governance is the formation of the board of directors. The most discussed issue, especially in European countries, is the gender diversity of boards of directors and its impact on company performance. The authors examined different points of view on this problem and the practice of solving it in different countries, incl. and in Russia. The authors noted the ambiguity of the results of empirical studies, as well as the prevalence of studies proving a positive relationship between the increase in the number of women on boards of directors and the performance of large companies. The article notes the need for a broad discussion on this topic in Russia. The authors consider it desirable to introduce gender quotas only for enterprises with state participation. For other enterprises, it is enough to indicate the recommendations in the Corporate Governance Code.

Authors: Ulfah Sofia
Published: March 2022

So far, Body Mass Index (BMI) is used as a measuring tool to assess a person's nutritional status. If there are two who have the same weight and height, they may have different nutritional status. Anthropometric measuring tools play a very important role in determining the nutritional status. The anthropometric guidelines for determining nutritional status are the parameters chosen and recommended, which include an assessment of age, weight, body length or height. On the other hand, technological developments are currently increasing and giving a great influence in almost every sector of life and the state. The process of globalization that occurs in every country in the world today also supports the development and use of technology. The need for information will increase along with the development of technology. Several methods are used to process large data to find the patterns contained in them, including the C4.5 Algorithm and the Naïve Bayes Classification Algorithm which are algorithms from the decision tree method and Bayes theorem. The C4.5 and NBC algorithms will be used for the classification of the nutritional status of children under five, which will be classified into five classes, namely normal, fat, very fat, thin, or very thin.

Сердечно-сосудистые заболевания (ССЗ) уносят каждый год более 4 млн жизней. В развитии ССЗ, связанных с атеросклерозом, доказана роль таких факторов, как сахарный диабет (СД), дислипидемия, ожирение. В связи с этим очень важны профилактика и лечение ССЗ и выявление групп риска, угрожаемых по развитию атеросклероза. Доказана роль уровня холестерина (ХС) липопротеидов низкой плотности (ЛПНП), который является ключевым фактором в развитии атеросклероза. В то же время необходимо провести оценку показаний у пациентов различных групп риска по шкале SCORE для решения вопроса о необходимости назначения гиполипидемической терапии. Статины являются лекарственными средствами выбора для лечения дислипидемий с мощной доказательной базой. В настоящее время появились новые гиполипидемические средства, которые обладают минимальным количеством неблагоприятных лекарственных реакций и могут использоваться в комплексной терапии дислипидемий. В статье проанализированы современные литературные данные и рекомендации Европейского общества кардиологов (ЕОК) по вопросам профилактики и лечения дислипидемий.

Cardiovascular diseases (CD) claim more than 4 million lives each year. Factors such as diabetes mellitus (DM), dyslipidemia, obesity have been proven in the development of atherosclerosis- related GCC. In this regard, the prevention and treatment of CD and the identification of risk groups threatened by atherosclerosis are very important. The role of cholesterol (CS) levels of low density lipoproteins (LDL), which is a key factor in the development of atherosclerosis, has been proven. At the same time, it is necessary to evaluate the indications in patients of different risk groups on a SCORE scale to decide on the need to prescribe hypolipidemic therapy. Statins are drugs of choice for the treatment of dyslipidemias with a powerful evidence base. At present, new hypolipidemic agents have emerged, which possess a minimal amount of non-critical drug reactions and can be used in complex therapy of dyslipidemias. The article analyses modern literary data and recommendations of the European Society of Cardiologists (ESC) on the prevention and treatment of dyslipidemia.

This study aims to examine the determinants of working children based on individual and environmental factors in urban and rural areas. The study draws on secondary data from various sources, including the March 2019 National Socio-Economic Survey (Susenas), the Indonesia Poverty Profile 2019, the Indonesian Education Statistics 2019, and the Indonesian Child Profile 2020. A multilevel binary logistic regression model was used as the analytical method. According to the study's findings, children have a greater proclivity to work in rural areas than in urban areas. The study's findings also show that children who smoke have a higher proclivity in both urban and rural areas. Further research indicates that individual factors, such as household size as measured by the number of household members, have a more significant influence on the determinants of children working in urban areas. Meanwhile, environmental factors significantly influence the determinants of children working in rural areas, precisely the percentage of children working in the informal sector and the school participation rate of 13-15 years old. The findings show that the determinants of working children in urban and rural areas are similar on an individual level but differ on an environmental level. Based on these findings, the government and related parties must encourage the reduction of smoking behavior in children in urban and rural areas to reduce the number of working children. Accelerating the decline in working children, particularly in rural areas, can increase school participation through improved educational quality and facilities.

Waste is exile generated from a production process that can have a negative effect onthe environment. Organic chicken manure that is produced naturally by utilizing Black Soldier Fly (BSF) larvae can produce BSF frass as organic fertilizer of good quality, environmentally friendly, which can support sustainable agriculture. Field experiments have been carried out in the Gardens of the Faculty of Agriculture, Winaya Mukti University, Tanjungsari District, Sumedang Regency. The purpose of the study was to determine the effect of the dose of chicken manure on the growth and yield of lettuce. The design used was a randomized block design consisting of 6 treatments, namely A = 0 tons ha-1, B= 3 tons ha-1 cow manure, C= 1.5 tons ha-1 BSF of chicken manure, D = 3 tons ha-1 , E = 4.5 ton ha -1 and F = 6 ton ha-1 and repeated 4 times. The results showed that the use of chicken manure BSF frass had a significant effect on growth in plant height, the number of leaves, and root volume, and lettuce yields had a significant effect on plant fresh weight, fresh weight per plot, root fresh weight, plant dry weight, root dry weight, and root loss ratio. At the dose of 6 tons ha-1 chicken manure cassava showed the best results on plant height, the number of leaves, fresh weight of each plant, fresh weight of each plot, plant dry weight, root dry weight, and root loss ratio.

Sorghum is one of the five most important cereal crops  in the world, due to its multi-beneficial usages and wide adaptability, so it has the high potential to be developed. One of the current efforts to develop sorghum is through a modern technique, molecular-based. Thus, in vitro culture is an indispensable basic technique, especially in the callus formation process. In addition to commercial synthetic chemicals, various organic materials found in nature have the potential to be used as PGR in initiating callus formation, one of which is honey. This study aims to obtain the optimum concentration of honey as a substituent of sorghum callus induction medium. The research design used a completely randomized design with one factor (honey concentration), which consisted of 5 dffrent levels (0, 5, 15, 25 and 35 gL-1). Observation variables consisted of callus formed (hsi), percentage of callus formation (%) and callus morphology. Data were analyzed using the F variance test and DMRT test at the 5% level. The test results of this study indicate that the two variables are significantly different. The fastest callus formation was in the M0 medium (0 gL-1.), while in the percentage of callus formation. The best results were in the M4 honey treatment (35 gL-1) of 77.78%. Thus it can be seen that the administration of honey as a substituent of in vitro culture media can help increase the success of sorghum callus formation.

Decisionismo democrático y emergencia permanente
Authors: Quiroga Hugo
Published: March 2022

Desde 1989 la democracia argentina no pudo prescindir del ejercicio de los poderes excepcionales y se alejó de aquella concepción que proclama la separación de poderes y los controles mutuos, que examina las posibles arbitrariedades de los gobiernos de turno. Cuando se refuerza al ejecutivo, el parlamento pierde poder y capacidad de control. Se trata de una verdadera práctica de gobierno denominada decisionismo democrático. En los hechos, es un medio para gobernar sin el respaldo central del Parlamento, que ya ha resignado atribuciones en determinadas materias mediante la delegación legislativa. El interrogante que conmueve y que atraviesa el contenido del artículo es saber si en la Argentina se puede gobernar sin acudir al decisionismo democrático. La prórroga ininterrumpida de la situación de emergencia la enviste de un carácter estructural, lo que refleja un cambio en la base del poder. En consecuencia, la emergencia permanente –soporte del decisionismo democrático- domina los asuntos más variados de la vida colectiva. La matriz del decisionismo democrático no se explica, entonces, sin la conexión estructural de los tres poderes del Estado. La práctica del decisionismo democrático exige una combinación del gobierno de los hombres, del gobierno atenuado del Estado de derecho y de la ausencia de poder de contralor.
Uruguay:

Uruguay ocupa los primeros lugares en América Latina en los rankings referidos a las dimensiones políticas de la democracia. Durante los quince años del gobierno de centro izquierda (2005-2020) no sólo no se denunciaron restricciones en materia de derechos y de libertades -como sí sucedió con otros gobiernos del signo similar en la región-, sino que se avanzó en la democratización e inclusión social y económica del país. En este artículo analizamos las claves de la estabilidad política uruguaya: centralidad de los partidos, identidades partidarias fuertes, parlamento activo, democracia directa y una tendencia a la negociación política y a la búsqueda de acuerdos entre los diversos actores políticos y sociales. En las elecciones de 2019 ganó una coalición de centro-derecha, con un presidente del tradicional y longevo Partido Nacional, Luis Alberto Lacalle. ¿Será el fin de una forma de gobernar? Además, mencionamos los riesgos que enfrenta la democracia ante la pandemia del Coronavirus mundial declarada en 2020 para un gobierno de derecha.
