20 años no es nada y 40… casi nada. La Constitución salvadoreña de 1983 en su 40 aniversario
Authors: Rodríguez Meléndez Roberto
Published: January 2024

La Constitución de la Republica de El Salvador cumple 40 años de vigencia en 2023. Es un texto cuya singularidad, tanto por el momento histórico en el que se produce, como por la serie de elementos que lo van configurando y moldeando merecen ser descritos. Me atrevería a afirmar, que más que el texto -que es muy típico de las constituciones de su época- es su contexto el que brinda a esta Constitución su singularidad. No muchas normas fundamentales en un país como El Salvador, han tenido una vigencia tan dilatada – de hecho, solo una constitución de finales del siglo XIX-. Dentro de su historia se encuentra el favorecer la inclusión como partido político de un grupo alzado en armas. Junto con los Acuerdos de Paz de 1992 y las reformas que estos propiciaron en el texto constitucional, podría considerarse como una norma clave en la formación al menos formal de un Estado de Derecho en El Salvador.
Este artículo busca profundizar en el contexto en el que surge la Constitución y como esta ha ido moldeándose para permitir la transición democrática en El Salvador, con los retos y desafíos que ello ha implicado a la fecha.

English learning with academic concepts improves pupils' hearing, speaking, reading, and writing. Method for doing it?
Authors: Al-Hikam Rafli Sandy
Published: January 2024

Integrative theme learning, or integrated thematic learning, is the method of seamlessly merging teaching and learning. One consequence of implementing the 2013 curriculum at Madrasah Ibtidaiyah or State Madrasah Ibtidaiyah is the integration of many general lesson subjects into a unified theme. This combination automatically results in a more significant disparity or distinction between the diverse range of teachings provided and the study of Islamic religious education. Therefore, it is crucial to develop the talent of integration, which involves combining knowledge from broad studies with the principles and values of Islam. This study aims to evaluate the degree of integration of the Islamic tenets in English language teaching at Islamic primary schools in East Java. The selected methodology for this research is a qualitative approach employing a case study method. The process of data collecting will encompass conducting interviews, making observations, and analysing pertinent documents. The findings suggest incorporating Islamic principles into English language education at MI Regency in East Java enhances students' listening, speaking, reading, and writing proficiency. This enhancement is accomplished by incorporating Islamic principles across multiple dimensions, encompassing philosophy, research methodologies, materials, strategies, and assessment. The selected method for integration at the communication level is standard communication. The story of integration in MI also necessitates support from scientific data, which will be further examined in this article.

Abstract. Volatile organic compounds (VOCs) play a crucial role in the formation of tropospheric ozone (O3) and secondary organic aerosols. VOC emissions are generally considered to have larger uncertainties compared to other pollutants, such as sulfur dioxide and fine particulate matter (PM2.5). Although predictions of O3 and PM2.5 have been extensively evaluated in air quality modeling studies, there has been limited reporting on the evaluation of VOCs, mainly due to a lack of routine VOC measurements at multiple sites. In this study, we utilized VOC measurements from the “Towards an Air Toxic Management System in China” (ATMSYC) project at 28 sites across China and assessed the predicted VOC concentrations using the Community Multiscale Air Quality (CMAQ) model with the widely used Multi-resolution Emission Inventory for China (MEIC). The ratio of predicted to observed total VOCs was found to be 0.74 ± 0.40, with underpredictions ranging from 2.05 to 50.61 ppbv (5.77 % to 85.40 %) at 24 sites. A greater bias in VOC predictions was observed in industrial cities in the north and southwest, such as Jinan, Shijiazhuang, Lanzhou, Chengdu, and Guiyang. In terms of different VOC components, alkanes, alkenes, non-naphthalene aromatics (ARO2MN), alkynes, and formaldehyde (HCHO) had prediction-to-observation ratios of 0.53 ± 0.38, 0.51 ± 0.48, 0.31 ± 0.38, 0.41 ± 0.47, and 1.21 ± 1.61, respectively. Sensitivity experiments were conducted to assess the impact of the VOC prediction bias on O3 predictions. While emission adjustments improved the model performance for VOCs, resulting in a change in the ratio of total VOCs to 0.86 ± 0.47, they also exacerbated O3 overprediction relative to the base case by 0.62 % to 6.27 % across the sites. This study demonstrates that current modeling setups and emission inventories are likely to underpredict VOC concentrations, and this underprediction of VOCs contributes to lower O3 predictions in China.
Large-eddy-model closure and simulation of turbulent flux patterns over oasis surface
Authors: Cao Bangjun , Shao Yaping , Yang Xianyu , Yin Xin , Liu Shaofeng
Published: January 2024

Abstract. Large-eddy simulations (LESs) have been increasingly used for studying atmosphere and land surface interactions over heterogeneous areas. However, parameterizations based on Monin–Obukhov Similarity Theory (MOST) often violate the basic assumptions of the very theory, generate inconsistencies with the LES turbulence closures, and produce surface flux estimates depending on LES model resolutions. Here, we propose a novel scheme for turbulent flux estimates in LES models. It computes the fluxes locally using the LES subgrid closure, which is then constrained on the macroscopic scale using MOST. Compared with several other schemes, the new scheme performs better for the various types of land surfaces tested. We validate our scheme by comparing surface flux estimates with field measurements obtained over an oasis surface at various height levels. Additionally, we scrutinize other quantities related to the surface energy balance, including net radiation, ground heat flux, and surface skin temperature, all of which align well with observational data. Our sensitivity experiments, focusing on model horizontal resolution, underscore the robustness of our scheme, as it maintains its corrective efficacy despite changes in horizontal grid spacing. We find that the macroscopic constraint imposed by MOST on LES-estimated fluxes strengthens as the horizontal grid spacing decreases, with a more pronounced influence on sensible than latent heat fluxes. These findings collectively highlight the promise and adaptability of our scheme for improved surface flux estimates in LES models.
Resilient Antarctic monsoonal climate prevented ice growth during the Eocene
Authors: Baatsen Michiel , Bijl Peter , von der Heydt Anna , Sluijs Appy , Dijkstra Henk
Published: January 2024

Abstract. Understanding the extreme greenhouse of the Eocene (56–34 Ma) is key to anticipating potential future conditions. While providing an end member towards a distant high-emission scenario, the Eocene climate also challenges the different tools at hand to reconstruct such conditions. Besides remaining uncertainty regarding the conditions under which the large-scale glaciation of Antarctica took place, there is poor understanding of how most of the continent remained ice free throughout the Eocene across a wide range of global temperatures. Seemingly contradictory indications of ice and thriving vegetation complicate efforts to explain the Antarctic Eocene climate. We use global climate model simulations to show that extreme seasonality mostly limited ice growth, mainly through high summer temperatures. Without ice sheets, much of the Antarctic continent had monsoonal conditions. Perennially mild and wet conditions along Antarctic coastlines are consistent with vegetation reconstructions, while extreme seasonality over the continental interior promoted intense weathering shown in proxy records. The results can thus explain the coexistence of warm and wet conditions in some regions, with small ice caps forming near the coast. The resilience of the climate regimes seen in these simulations agrees with the longevity of warm Antarctic conditions during the Eocene but also challenges our view of glacial inception.
Mapping geochemical anomalies by accounting for the uncertainty of mineralization-related elemental associations
Authors: Wang Jian , Zuo Renguang , Liu Qinghai
Published: January 2024

Abstract. Geochemical mapping is a fundamental tool for elucidating the distribution and behaviour of economically significant elements, and providing valuable insights for geological processes. Nevertheless, the quantification of uncertainty associated with geochemical mapping has recently become a subject of widespread concern. This study presents a procedure, primarily involving the determination of homogeneous clusters, the recognition of elemental associations for each cluster, and the identification of geochemical anomalies, with the aim to account for the uncertainty of elemental association in geochemical mapping. To illustrate and validate the procedure, a case study was conducted wherein stream sediment geochemical samples from the northwestern Sichuan Province, China were processed to map anomalies associated with disseminated gold mineralization. The results indicate: (1) the representativeness of elemental association for the underlying geological process is an important source of uncertainty for geochemical mapping, (2) the procedure presented here is effective to incorporate the uncertainty of elemental association in geochemical mapping, and (3) the study area can be classified into two clusters, each characterized by unique elemental associations that align well with the distribution of Paleozoic and Triassic lithological units, respectively. Furthermore, the region still holds great potential for the discovery of gold deposits, particularly in areas proximal to known mineralization sites.
A Study of Sea Ice Topography in the Weddell and Ross Seas Using Dual Polarimetric TanDEM-X Imagery
Authors: Huang Lanqing , Hajnsek Irena
Published: January 2024

Abstract. The sea ice topography is essential for understanding the interactions within the air-ocean-ice system. Single-pass interferometric synthetic aperture radar (InSAR) allows for the generation of digital elevation model (DEM) over the drift sea ice. However, accurate sea ice DEMs (i.e., snow freeboard) derived from InSAR are impeded due to the radar signals penetrating the snow and ice layers. This research introduces a novel methodology for retrieving sea ice DEMs using dual-polarization interferometric SAR images, considering the variation in radar penetration bias across multiple ice types. The accuracy of the method is verified through photogrammetric measurements, demonstrating the derived DEM with a root-mean-square error of 0.26 m over a 200 x 19 km area. The method is further applied to broader regions in the Weddell and the Ross Sea, offering new insights into the regional variations of sea ice topography in the Antarctic. We also characterize the non-Gaussian statistical behavior of sea ice elevations using log-normal and exponential-normal distributions. The results suggest that the exponential-normal distribution is superior in the thicker sea ice region (average elevation >0.5 m, whereas the two distributions exhibit similar performance in the thinner ice region (average elevation <0.5 m). These findings offer an in-depth representation of sea ice elevation and roughness in the Weddell and Ross Sea, which can be conducted in time series data to comprehend sea ice dynamics, including its growth and deformation.
Towards a Harmonized Operational Earthquake Forecasting Model for Europe
Authors: Han Marta , Mizrahi Leila , Wiemer Stefan
Published: January 2024

Abstract. We develop a harmonized earthquake forecasting model for Europe based on the Epidemic-type Aftershock Sequence (ETAS) model to describe the spatio-temporal evolution of aftershock sequences. We propose a method modification that integrates information from the European Seismic Hazard Model (ESHM20) about the spatial variation of background seismicity during ETAS parameter inversion based on the expectation-maximization (EM) algorithm. Other modifications to the basic ETAS model are explored, namely fixing the productivity term to a higher value to balance the more productive triggering by high-magnitude events with their much rarer occurrence, and replacing the b-value estimate with one relying on the b-positive method to observe the possible effect of short-term incompleteness on model parameters. Retrospective and pseudo-prospective tests demonstrate that ETAS-based models outperform the time-independent benchmark model as well as an ETAS model calibrated on global data. The background-informed ETAS variant achieves the highest score in the pseudo-prospective experiment, but the performance difference to the second-best model is not significant. Our findings highlight promising areas for future exploration, such as avoiding the simplification of using a single b-value for the entire region or reevaluating the completeness of the used seismic catalogs.
A coarse pixel-scale ground “truth” dataset based on global in situ site measurements to support validation and bias correction of satellite surface albedo products
Authors: Pan Fei , Wu Xiaodan , Zeng Qicheng , Tang Rongqi , Wang Jingping , Lin Xingwen , You Dongqin , Wen Jianguang , Xiao Qing
Published: January 2024

Abstract. In situ measurements from sparsely distributed networks worldwide are a critical source of reference data for validating or correcting biases in satellite products. However, due to the substantial difference in spatial scales between in situ and satellite measurements, the two cannot be compared except for the fact that the underlying surface of in situ sites is absolutely homogeneous. Instead, the in situ measurements needed to be upscaled to be matched with the satellite pixels. Based on the upscaling model, we also proposed the consideration that in situ observation generally lacks spatial representativeness due to the widely distributed spatial heterogeneity, and we have developed a coarse pixel-scale ground “truth” dataset based on ground measurements of 416 in situ sites from the sparsely distributed observation networks. Furthermore, we thoroughly assessed the effectiveness of the dataset at sites with different degrees of spatial representativeness. The results demonstrate that using this dataset in validation outperforms the direct comparison between satellite and in situ site measurements over heterogeneous surfaces when in situ measurement footprints are less than satellite pixel size. The accuracy of the reference data employed for validation or bias correction can be boosted by 17.09 % over the regions with strong spatial heterogeneity. However, the degree of improvement with this dataset displays a decreasing trend with the reduction in spatial heterogeneity. At a global scale, the pixel-scale ground “truth” dataset enhances the accuracy of pixel-scale reference data in general, with the overall relative root-mean-square error (RRMSE) decreasing by 6.04 % compared to in situ single-site measurements. Our results suggest that in situ single-site measurements are limited in their ability to capture surface spatial variability information at a coarse pixel scale (i.e., the kilometer scale). The dataset we provided, which merges temporal information from ground-based observations and spatial information from high-resolution data, represents a valuable resource for validating and correcting worldwide surface albedo products over heterogeneous surfaces. To the best of our knowledge, this dataset is unique in providing a coarse pixel-scale ground “truth” with the widest spatial distribution and longest time series. The dataset is publicly available through https://doi.org/10.5281/zenodo.8008454 (Pan et al., 2023).
Compound flood impacts from Hurricane Sandy on New York City in climate-driven storylines

Published: January 2024

Abstract. High impact events like Hurricane Sandy (2012) significantly affect society and decision-making around weather/climate adaptation. Our understanding of the potential effects of such events is limited to their rare historical occurrences. Climate change might alter these events to an extent that current adaptation responses become insufficient. Furthermore, internal climate variability in the current climate might also lead to slightly different events with possible larger societal impacts. Therefore, exploring high impact events under different conditions becomes important for (future) impact assessment. In this study, we create storylines of Sandy to assess compound coastal flooding on critical infrastructure in New York City under different scenarios, including climate change effects (on the storm and through sea level rise) and internal variability (variations in the storm's intensity and location). We find that 1 m of sea level rise increases average flood volumes by 4.2 times, while maximised precipitation scenarios (internal variability) lead to a 2.5-fold increase in flood volumes. The maximised precipitation scenarios impact inland critical infrastructure assets with low water levels, while sea level rise impacts fewer coastal assets though with high water levels. The diversity in hazards and impacts demonstrates the importance of building a set of relevant scenarios, including those representing the effects of climate change and internal variability. The integration of a modelling framework connecting meteorological conditions to local hazards and impacts provides relevant and accessible information that can directly be integrated into high impact event assessments.
Stability and uncertainty assessment of geoelectrical resistivity model parameters: a new hybrid metaheuristic algorithm and posterior probability density function approach
Authors: Sarkar Kuldeep , Tiwari Jit V. , Singh Upendra K.
Published: January 2024

Abstract. Estimating a reliable subsurface resistivity structure using conventional techniques is challenging due to the nonlinear nature of the inverse problems. The performance of the inversion techniques can be pretty ambiguous based on the optimal error, although traditional methods have proven to be quite effective. In this work, the impacts of the constraints accessible from a borehole are examined for further assessment and to enhance algorithm effectivity. The vPSOGWO strategy is a new approach that is based on a model search space without any prior information, and it describes the hybridization of particle swarm optimization (PSO) with the Grey Wolf Optimizer (GWO). To understand the efficiency and novelty of the algorithm, it has been validated on two different kinds of synthetic resistivity data with various sets of noise and, subsequently, applied to three field datasets of different geological terrains. The analyzed results suggest that the subsurface resistivity model shows considerable uncertainty. Thus, it is superior to examine the histograms and posterior probability density functions (PDFs) of such solutions to exemplify the global solution. A PDF with a 68.27 % confidence interval (CI) selects a region with a higher probability. Therefore, the inverted models are used to estimate the mean global solution and the most negligible uncertainties, where the mean global solution represents the best solution. Our vPSOGWO-inverted outcomes have been proven to be more accurate than classic PSO, GWO, and state-of-the-art variants of classic approaches. As a result, this novel method plays a vital role in vertical electrical sounding (VES) data inversion.

Abstract. The inter-dataset agreement of trends in subweekly near-surface (850 hPa) temperature variability over Southern Hemisphere midlatitude land masses is assessed among 12 global atmospheric reanalysis datasets. A comparison of the climatological temperature variance and dominant sources and sinks of the variance reveals that, except for NCEP-NCAR (R1) and NCEP-DOE (R2), there is a relatively good agreement for their magnitudes and spatial distributions during the satellite era (1980–2022), which indicates that the key features of subweekly variability are sufficiently well represented. A good agreement is noted for the positive trends found in subweekly variability over the satellite era affecting South Africa in September–October–November (SON) and South America in December–January–February (DJF). Although there is agreement in most of the reanalyses concerning the positive trend affecting Australia in SON, this has not yet emerged from the noise associated with interannual variability when considering only the satellite era. It is significant, however, when the period is extended (1954–2022) or limited to the most recent decades (1990–2022). The trends are explained primarily by a more efficient generation of subweekly temperature variance by horizontal temperature advection. This generation is also identified as a source of biases among the datasets. The trends are found to be reproduced even in those reanalyses that do not assimilate satellite data (JRA-55C) or that assimilate surface observations only (ERA-20C, 20CRv2c, and 20CRv3).

In essence, in the world of work, of course, it is very necessary for human resources who have a work ethic with high motivation to increase work productivity and as a form of real example of a commitment in order to achieve the goals that have been set. To improve and make morale (work ethic) always present and tend to grow, one of the things that is very important to pay attention to is implementing a reward and punishment system. The policy of implementing rewards and punishments is expected to be a stimulus to improve the culture of maximum performance because performance is a real behavior displayed by each employee as an achievement in accordance with his role (rights and obligations) in an agency. The concept of mashlahah is the path taken by Islamic law to implement His rules and commandments against new events that are not accommodated in the nash, as an effort to create goodness that is long-term (hereafter dimension) and short-term (worldly dimension), material and spiritual and includes collective and individual aspects. In addition, three main elements must be fulfilled, namely sharia compliance (halal causa), having benefits and bringing goodness (thayyib) in various aspects universally that do not cause harm.

Privatization of State-Owned Enterprises (BUMN) in Indonesia. Privatization is undertaken with the intention of enhancing company performance, contributing to the country's economy, and improving less efficient management. However, there are concerns regarding the loss of economic sovereignty through privatization. The Indonesian government has implemented a privatization policy based on the 1999 GBHN and the 2003 BUMN Law. Privatization has various dimensions and objectives, including reducing the state's role in the economy, increasing management efficiency, and filling the state budget deficit. The role of BUMN in development has been significant, but there have also been cases of poor management and financial losses. Privatization of BUMN is considered to overcome this problem and improve company performance. However, there are challenges in achieving professionalism and competitiveness in BUMN because employee status is like civil servants. There is also controversy regarding privatization, with some arguing that certain sectors should remain under government control in the interests of the economy. The privatization of BUMN is regulated by the BUMN Law, which emphasizes the importance of transparency, accountability, and fairness in the privatization process. However, there are concerns regarding the consistency of these regulations with the Constitution. Therefore, it is recommended that there be restrictions on the sale of shares during privatization and that the government maintain majority ownership of the shares. Apart from that, a clear definition is needed for the purpose of privatization and more detailed regulations in the BUMN Law.
