Desde el Departamento de Investigación de la Universidad De La Salle, la Universidad DLa Salle Bajío en México y la Red Internacional de Estudios sobre Interculturalidad (RIEI), celebramos la publicación de esta nueva edición de la Revista REDpensar “Dossier Internacional de Estudios sobre Interculturalidad e Investigación.”, del volumen 12, número 2.  En este número especial, REDpensar se ha dado a la tarea de conjuntar seis trabajos emanados de diversas investigaciones dedicadas a cuestionar el devenir de aquello que, desde diferentes trincheras, hemos denominado interculturalidad, la cual sigue reclamando una visión más convergente y plural en sus diferentes ámbitos de aplicación.

Si bien la historia en torno al concepto es amplia, ante la multiplicidad de perspectivas y escenarios vertidos en este número hemos recuperado la idea de lo intercultural en tanto modelo de sociedad en donde, al menos, resalta la necesidad sobre: a) La igualdad de oportunidades para todas las personas al compartir un mismo espacio y tiempo, b) El respeto a la diversidad y c) La creación de entornos sociales que posibiliten el intercambio y el enriquecimiento mutuo entre sujetos de orígenes étnicos o culturales distintos (Essomba, 2006, p. 44).

A partir de estos manuscritos y reportes investigativos, las personas autoras nos invitan a reconocer nuestras identidades como actores socioculturales e históricos, por un lado, y como actores políticos dotados de derechos fundamentales y universales, por otro. Nos invitan a transitar hacia un pensamiento abierto y complejo, en donde la interculturalidad sea mediadora y convergente para, de ese modo, asumir que la diversidad cultural es un asunto dinámico y que permea a la población en general.

Esperamos sea del agrado y disfrute esta valiosa publicación.

Avatares de la interculturalidad en un contexto escolar: el makem y las mujeres de Tierra Colorada, Chiapas
Authors: Hernández Silvano Adriana , Ortega Rodríguez Emma Hilda
Published: December 2023

Este trabajo muestra un análisis inédito sobre el makem -una práctica sociocultural previa a la unión matrimonial- dentro de la cultura tseltal de Tierra Colorada, ubicada en Tuxtla Gutiérrez, Chiapas. A través de una etnografía educativa (Bertely, 2000) cuyo objetivo principal fue descifrar cómo se construye la identidad de la mujer indígena (Yánez, 2006; Hall y Gay, 2003; Giménez, 2007), se muestra el punto de inflexión entre el desarrollo profesional de las niñas en una relación de makem y su deber cultural en la comunidad, además, se resalta el hecho de que la escuela es un escenario formal en donde se reproducen ideologías de género (Lamas, 1997) tendientes a la inequidad y violencia, aun cuando dicha institución sea de corte intercultural (Walsh, 2009). Con lo anterior, se discute la paradoja de si la escuela debiera ser un espacio para la reivindicación de los derechos humanos y con perspectiva de género, aun cuando los rasgos identitarios del grupo en cuestión no empaten, necesariamente, con dichos preceptos..

Authors: Lv Sizhong , Wang Yansheng , Wang YAO , Lin Chunjin , Zhang Ming , Li Zhaofeng , Li Xuan
Published: December 2023

Pile-side grouting is the main method to enhance the bearing capacity of in-service pile foundation, the formation parameters have complicated influence on the grouting reinforcement effect. For the problem of inadequate bearing capacity of friction piles in service in alluvial river plains, the effect of the parameters of the complex strata of silty clay and fine sand on the bearing capacity of friction piles reinforced by extrusion grouting was investigated by model tests. When the thickness ratio of powdered clay and fine sand stratum changes from 1:3 to 3:1, the proportion of powdered clay in the stratum increases, and the bearing capacity of the pile foundation decreases by about 50∼100 N. The internal friction angle of fine sand is larger with the particle size increase, and the load transfer efficiency is higher, so the effect of pile side compaction grouting reinforcement is more pronounced. Meanwhile, the water content of powdered clay plays a negative role in the impact of pile foundation grouting reinforcement.
Surrounding Rocks Stability Analysis of Circular Tunnel Using Strength Reduction Method and Sliding-t Test
Authors: Du Yiqian , Ke Song , Kong Yang
Published: December 2023

SRM (strength reduction method) is a kind of numerical limit method widely used in stability analysis of geotechnical engineering. This paper introduced the origin, basic principles, and operation process of SRM firstly, then introduced a new type of SRM considering the “strength reduction shortest path”. Moreover, both two methods were applied to solve the safety factor of an identical simulation model. In addition, sliding-t test was engaged to determine the accurate abrupt change position of the feature point’s displacement, which presented considerable operability and accuracy. Finally, it was concluded that this new type SRM is more conservative than the traditional SRM, and the calculated safety factor of the same simulation model is about 25% lower.

Published: December 2023

With the continuous increase in urbanization and population density, the prevalence of super high-rise buildings is rapidly growing. To ensure occupants’ safety, especially during emergencies such as fires and earthquakes, it is essential to establish effective evacuation planning and guidance systems. Unfortunately, there is currently a lack of efficient solutions specifically designed to guide the evacuation of personnel in super high-rise buildings during fire incidents. This study develops a dynamic evacuation guidance system that utilizes the Dijkstra’s algorithm and A* algorithm. By considering the unique characteristics of super high-rise buildings, the system aims to provide efficient and secure evacuation path selections. Furthermore, it dynamically guides occupants to avoid areas at high risk of fire, thereby preventing crowd congestion accidents. This study seeks to bridge the existing gap by presenting a relatively efficient solution for guiding the evacuation of personnel in super high-rise buildings during fire incidents.

Based on the comprehensive analysis of the basic parameters of the reservoir dam, the engineering hydrogeological conditions and the internal relationship between the time and space deformation of the valley and the reservoir dam after impoundment, a three-dimensional model of about 500 m on the left and right banks of transverse river direction is established for dynamic simulation. The deformation and stress evolution of the high slopes of rock and soil on both sides of the dam area of a large power project are simulated by using finite element method and finite difference method, and the development law of deformation, stress distribution and the change characteristics of internal unbalanced force are analyzed, as well as the deformation speed of the high slopes on both sides of the river in the direction of facing the airport and the speed of valley deformation. The research results can provide reference for the stress distribution, valley deformation law and safety monitoring of rock mass on both banks in design and research of dam engineering.

Authors: Wang Lining , Wang Fengchi , Chong Bowen
Published: December 2023

In the research process of glass concrete performance, the basic mechanical properties are the basis of the research, and the fracture performance is an important index to evaluate the working performance of glass concrete. The glass aggregates with different substitution rates and different particle sizes were selected to replace the coarse and fine aggregates in the concrete, and the three-point bending beam test was carried out to discuss the fracture energy and fracture toughness under the freeze-thaw and sulfate attack environment. The results show that the sulfate attack environment not only improves the fracture energy of the glass concrete specimen, but also improves the instability toughness of the glass fine aggregate to replace the larger proportion of the specimen, but at the same time, it also reduces the fracture toughness of the specimen. In the freeze-thaw environment, only the fracture energy of the specimen with glass instead of fine aggregate is increased, and with the increase of the number of freeze-thaw cycles, the fracture toughness of the glass concrete is reduced.
Study on Regulation Measures for Influence of Tributary to Navigation in Tidal Reach
Authors: Zhang Yanyan , Zou Huazhi , Zhang Kang , Zhang Liangliang , Yi Lisha , Deng Yueyun
Published: December 2023

This article intends to use physical model tests and take the Water Conservancy Project of Zhongshun Dawei Baihuatou as an example to simulate the impact of flood drainage from the Inner River on the navigation of the outer river under the condition of sluice and pump joint adjustment. Regulation measures were proposed for the impact of flood drainage on navigation. The principle of the regulation measures is to set up two rows of diversion piers at the intersection of the inner and outer rivers. The function of the row of diversion piers next to the Inner River is to evenly divide the water flow from the Inner River into several streams. The second row of diversion piers are arranged staggered with the first row with an angle of 45°. The function is to disperse the scattered water flow, using the principle of multiple water flow collision to dissipate the energy, so as to achieve the purpose of speed reduction. The remediation technology has universal applicability and can be applied to river sections of similar projects, which is of great significance to promoting the development of shipping in the Pearl River Delta.

Authors: Zhang Xu , Jin Heping , Lin Yifeng , Jiang Juan , Luo Huiheng , Wang Shuyang , Xiao Jiandong , Wu Caihong
Published: December 2023

In order to strengthen the monitoring of mountain deformation and the stability of high slope engineering in hydropower projects, taking a high slope in the spillway tunnel of a super-large hydropower project as an example, we calculated the slope stability of plunge pool through the finite element strength reduction method. The calculation results reveal the deformation characteristics and safety situation of high slope. Many factors, such as the structure, lithology, slope shape, excavation amount, unloading effect and engineering construction disturbance, will affect the failure mode of the slope. If the slope is not controlled by significant structural plane, the slope is controlled by progressive deformation. The key to ensure the stability of the slope lies in the control of the slope deformation, which can be intervened in advance through protective or control measures to control its de-formation and development manually. At present, the slope is in the deformation stage, and has not yet formed a unified potential sliding surface, and the whole slope is basically stable.

Authors: Zhong Caimin , Chen Yiqiang
Published: December 2023

In this paper, a mechanical model of the top chord of a half through truss bridge is established, and the influence of the web on the buckling critical force of the top chord is analyzed by using the energy method. The derived equation is in good agreement with the formula (A1.38) in Chen Ji [9], which verifies the correctness of the formula in this paper. In order to analyze the influence of the web torque on the buckling critical force of the top chord, the buckling critical force of the top chord under three different condition are discussed, which are considering the axial force and torque of the web on the top chord, only considering the torque of the we on the top chord and considering the partial coupling of the web. The results show that the top and lower limits of the influence of the web torque are obtained when the axial force and torque of the web on the top chord are considered and only the torque of the web on the top chord is considered.

Authors: Zhong Dongwang , Li Tengfei , Tao Haohao , Lv Quan , He Li
Published: December 2023

During the demolition of a single-tower cable-stayed bridge, the initiation delay time of each blasting incision is determined by the deflection angle of the main tower, and the steel cable of the cable-stayed bridge directly affects the instability and dumping of the main tower due to the complex stress. In this paper, the fixed-axis rotation of the rigid body is combined with the kinetic energy theorem to obtain the functional relationship between the deflection angle of the main tower and the time. Under the condition of satisfying the model similarity theory, the time required for the main tower to deflect each angle is measured by using a high-speed camera. Studies have shown that the deflection of the main tower at 3° takes 3.52 seconds, and the force of the bridge deck acting on the main tower through the steel cable does not exceed 42.15% of its own weight. This conclusion can provide a reference for other projects in the industry.

Published: December 2023

Plateau lake is an ideal integrator of regional climate, which can integrate and amplify local climate, and highly sensitive to climate responses. The Qinghai Lake is one of the most sensitive areas to climate change. To systematically analyze the changes and future trends of precipitation and temperature in the Qinghai Lake Basin under the background of climate change, based on the fact of climate change, this study intends to select suitable emission scenarios and predict the future trend of precipitation and temperature in the study area, combined with the latest climate model achievement CMIP6. The results show that the future precipitation and temperature will increase in Qinghai Lake Basin due to climate change and carbon emissions, and the temperature will be more significantly affected by carbon emissions. The increasing trend of temperature is more obvious than that of precipitation. This study will provide reference for the future climate change trend and quantitative analysis of plateau lakes.
The Development of Planar Soil Erosion from the Action of Meltwater in the Central Part of the Krasnoyarsk Forest-Steppe
Authors: Golubev I.A.
Published: December 2023

The importance of a detailed study of water-erosion processes on the treated slopes is due to the damage caused by these processes to the valuable humus horizon of soils and, as a result, losses of soil fertility. When plowing the land, the soil cover is deprived of anti-erosion protection from natural vegetation. During the snowmelt period, the surface melt runoff interacts with the surface of unprotected or poorly protected cultivated lands, causing accelerated water erosion processes. The results of field studies of soil flushing and accumulation on arable land in the central part of the Krasnoyarsk forest-steppe (Middle Siberia) in the period 2009–2011 are presented. The development of erosion processes is influenced by both the conditions of the underlying surface and hydrometeorological factors. The significant role of the previous autumn moistening of soils, the intensity of water supply to the soil during snowmelt is noted. In the study area, detailed observations of planar soil erosion were previously carried out very little, their results were not published and were largely lost. These data allow us to fill this gap to a certain extent.
Waveform Indication Inversion Method Optimization
Authors: Guan Liqun
Published: December 2023

Reservoir development is complicated, so it is limited to use well pattern data or seismic data alone. The development of seismic inversion technology is becoming more and more mature, and remarkable results have been achieved in reservoir prediction, but the sparse pulse inversion and geostatistics inversion have the disadvantages of low resolution and high randomness. With the increasing difficulty of oilfield development, the prediction of thin layer is particularly important. Taking Block A as an example, according to the development characteristics of different reservoir groups, the inversion method of well vibration combined with waveform indication suitable for the reservoir characteristics of the study area is optimized. The simulation method of spontaneous potential curve waveform is applied to the Saltu and Puhuhua reservoirs, while the target probability simulation method is applied to the Gaotaizi reservoirs.

Published: December 2023

In order to research the flow characteristics within the double-suction centrifugal pump, 650SY80-HY type pump is used to research, and the RNG k-ε turbulence model is selected to research and analyze the flow field within the double-suction pump under different working conditions. The results show that: the error between the results of the simulation and experimental is within an acceptable range, which verifies the precision of the numerical simulation; Under different conditions, the pressure distribution of the blade is uniform, and there is less pressure on the blade head; Under the 0.8Qd condition, due to the impact of water flow on the initial end of the partition, there is a large area of low velocity zone outside the partition, resulting in a large energy loss; The turbulent kinetic energy (TKE) mainly exists in the outside of the partition under the 0.8Qd condition, while the TKE mainly exists in the tongue under the 1.2Qd condition. Under the design condition, the vortex in the impeller channel is obviously less than that under the off-design condition. This study provides a basis for further optimization of the design of double suction pump.

Connected vehicles will gradually become important participants of expressways in the future. However, evaluations for driving safety when there are increasing connected vehicles on expressways are not sufficient. To address the issue, this research makes driving safety evaluations of ramp merging and vehicle following under low-visibility events, two typical V2X scenarios on expressways, through a SUMO simulation approach. The simulation is carried out based on the topology map of the Changtai Expressway, one of the leading V2X demonstration projects in China. Three indicators, namely ‘Number of Decelerations’, ‘Average Speed’, and ‘Number of Abnormal Acceleration’, are continually analyzed to evaluate driving safety on the expressway. The results show that the number of decelerations and abnormal acceleration generally decreases while the average travel speed gradually rises when the market share of connected vehicles grows. Therefore, the safety evaluation indicators perform better under a higher share of connected vehicles, which is encouraging in developing V2X on expressways.

Climate change forces policy-makers to undertake actions to reduce human impact on socio-environmental system. One of the directions is to shift into low-carbon economy, also by increasing the role of renewable energy sources (RES) in energy sector. Therefore, there is a need to support local stakeholders with a knowledge-based approaches in order to implement RES more effectively. There are some systems assessing natural potential for RES installations, however, legal regulations are not always making it possible everywhere. The aim of this research is to expand existing functions of the decision support system for hybrid RES by the feasibility assessment of selected locations due to legal regulations. The developed tool was applied and presented on the case of a selected Polish region. The RES potential is assessed based on the universal databases (Global Wind Atlas, Global Solar Atlas, CORINE Land Cover), however, it was customized to local legal regulations, which allows the solution to be more practical and helpful for implementation in a low-carbon economy. Promotion of decision support systems for RES planning may constitute effective solution to reach goals set in the European Green Deal.
A Note on Hierarchical Constraints
Authors: Bench-Capon Trevor
Published: December 2023

In recent years a considerable amount of research has been devoted to formal theories of precedential constraint. In this note I consider a recent paper which explores the use of factor hierarchies in this connection. In that work it was shown both that cases constrained with the use of a hierarchy may be unconstrained if the hierarchy is flattened, and that cases unconstrained with a hierarchy may be constrained when the hierarchy is flattened. I discuss the nature of factor hierarchies and attempt to explain these results.
Inferring New Classifications in Legal Case-Based Reasoning
Authors: Di Florio Cecilia , Liu Xinghan , Lorini Emiliano , Rotolo Antonino , Sartor Giovanni
Published: December 2023

This article continues the research initiated in [1,2], which established a connection between Boolean classifiers and legal case-based reasoning. We relax the assumption that case bases are such that all situations have been decided in favour of the defendant or the plaintiff and we introduce an inductive strategy for assigning plausible outcomes to undecided cases. Using counterfactual reasoning, we propose a method to determine whether, at each step of the induction, a feature is a factor, i.e., it consistently favours a single outcome, or is irrelevant, i.e., it is does not favour any outcome, or is ambiguous, i.e., it favours opposite outcomes.
Arguing About Choosing a Normative System: Conflict of Laws
Authors: van Berkel Kees , Markovich Réka , Strasser Christian , van der Torre Leendert
Published: December 2023

This paper presents a formal model of specific reasoning patterns in conflict of laws (CoL). CoL arises when multiple countries have jurisdiction due to the diverse nationalities of the involved factors. When initiating legal action in one country, the question of which country’s substantial law to apply emerges, possibly involving the CoL regulations of other countries (in cases of transmission and renvoi). Moreover, parties contemplating legal action in a case falling under CoL often engage in a deliberation process known as forum shopping: determining which country’s CoL regulations would result in the most favorable outcome for them. Our model integrates deontic logic (specifically Input/Output logic) with proof theory and formal argumentation techniques to model both types of reasoning.
Dimensions and Precedential Constraint: Factors Deriving from Multiple Dimensions
Authors: Bench-Capon Trevor , Atkinson Katie
Published: December 2023

Current theories of precedential constraint attempt to incorporate dimensions into the reasons for decisions. We argue that this is an unnecessary complication, and precedential constraint can be handled using only factors. In our account the role of dimensions is to organise facts, and their effect operates at the factor ascription level, prior to precedential constraint being applied.

Published: December 2023

The purpose limitation principle is a GDPR cornerstone that aims to minimize data processing risks by limiting instances of personal data access and usage. We model purpose as an action or sequences of actions and formalize action relationships to derive purpose-based permissions. Based on these permissions, we introduce a novel purpose-based access control model with a purpose matching algorithm illustrated with a healthcare research use case.
Connecting Rule-Based and Case-Based Representations of Soft-Constraint Norms

Published: December 2023

To exhaustively understand the impact of rule amendments and unforeseen cases on existing norms, it requires connecting their rule-based and case-based representations. However, those connections have not been explored in depth, especially for norms that are represented as soft constraints. This paper aims to explore the connection between constraint hierarchies and case models as representative formalisms of rule-based and case-based representations of soft-constraint norms respectively. To explore the connection, we express norm scopes and preferences in both formalisms as diagrams. Based on tightening and arranging diagrams, we found the translation of constraint hierarchies with one constraint per level into case models. This provides new insights into understanding prototypical cases made by rule-based soft-constraint norms.
Can GPT Alleviate the Burden of Annotation?
Authors: Gray Morgan , Savelka Jaromir , Oliver Wesley , Ashley Kevin
Published: December 2023

Manual annotation is just as burdensome as it is necessary for some legal text analytic tasks. Given the promising performance of Generative Pretrained Transformers (GPT) on a number of different tasks in the legal domain, it is natural to ask if it can help with text annotation. Here we report a series of experiments using GPT-4 and GPT 3.5 as a pre-annotation tool to determine whether a sentence in a legal opinion describes a legal factor. These GPT models assign labels that human annotators subsequently confirm or reject. To assess the utility of pre-annotating sentences at scale, we examine the agreement among gold-standard annotations, GPT’s pre-annotations, and law students’ annotations. The agreements among these groups support that using GPT-4 as a pre-annotation tool is a useful starting point for large-scale annotation of factors.
New Horizons of Legal Judgement Predication via Multi-Task Learning and LoRA
Authors: Sun Ren-Der , Chang Chia-Hui , Chien Kuo-Chun
Published: December 2023

Legal Judgment Prediction (LJP) aims to predict the judgement results (such as legal article, charge and penalty) based on the criminal facts of the case. Most previous research in this field was based on criminal statements from court verdicts. However, each verdict actually is based on the content from indictments. For prosecutors, will the case be dismissed or processed? If the case is accepted, is the penalty a jail sentence or a fine? What is the charge and article violated? In this study, we therefore define three novel LJP tasks for prosecutors, including prosecution outcome prediction (LJP#1), imprison prediction (LJP#2) and fine prediction (LJP#3). We explore various multi-task learning (MTL) framework based on Word2Vec and BERT language model (LM) with either topology-based or message-passing mechanism. Moreover, we employed the LoRA (Low-Rank Adaptation) technique to save both computation time and resources during fine-tuning. Experimental results demonstrated that Word2Vec-based model combined with message passing architecture still has the potential to outperform large LM like BERT, while BERT-based models with a simple parallel architecture generally performed well. Finally, using LoRA for fine-tuning not only reduced training time (by 45%) but also improved performance (2.5% F1) in some LJP tasks.
Centrality Scores and Precedent Value in Legal Network Analysis
Authors: van Dijck Gijs , Rodrigues de Miranda Benjamin , Crombach Chloé
Published: December 2023

Courts commonly rely on precedents to guide their judgments. Centrality measures have been used to calculate precedence value in citation networks of judgments, yet it remains largely unknown whether and which centrality measures correlate well to precedent value. An analysis of European Court of Human Rights (ECtHR) judgments offers a unique opportunity to uncover this relationship, as the ECtHR publishes an importance score for its judgments and the branch of court that dealt with them. These scores, although not perfect, may serve as proxies for a case’s precedent value. Various network centrality measures correlated reasonably with these proxies, with Degree being a stable measure across the (sub)networks. An ordinal regression model with network centrality among other predictor variables performed reasonably when Importance Score was used as an outcome variable (F1 ≈ .655). The results support that network centrality, to an extent, indicates case precedent value, and that Degree seems to be a stable proxy for precedent value across different networks. The data, code, and additional results are made available.
