Authors: Gonzáles Chávez Salomé
Published: August 2023

El análisis univariante de series temporales ARIMA (Autoregressive lntegrated Moving Average), basado en que una serie temporal obedece a un proceso estocástico, se ha utilizado para describir y predecir el comportamiento futuro de las series energéticas de mayor representatividad dentro la oferta y consumo de energía en el Principado de Asturias- España. En primer lugar, cada una de estas variables se han contabilizado mensualmente desde 1980 hasta 1996. De acuerdo a las características de cada serie - poseen tendencia, estacionalidad y el tamaño muestral suficiente - se procede a calcular qué modelo ARIMA univariante describe mejor a cada una de ellas. La aplicación de esta metodología consiste en calcular las predicciones de las principales variables energéticas de Asturias. Los resultados obtenidos han alcanzado un alto nivel de aproximación predictiva los cuales sirven como elementos de referencia en el proceso de Planificación Energética de Asturias.
Ponderación de los promedios del colegio en la Admisión-UNI
Authors: Ordoñez Mercado Alipio
Published: August 2023

En el proceso de selección de postulantes a la UNI se consideran dos notas: la del examen de admisión y la nota promedio obtenida en el Colegio. En este trabajo se considera el problema de asignarles ponderaciones apropiadas a estas notas. Para el efecto, usamos un modelo lineal de media constante con dos restricciones y los datos de los diez exámenes de admisión realizados entre 1995-1999. El análisis estadístico sugiere que las ponderaciones apropiadas deben ser 0.94 y 0.06 respectivamente. Estas ponderaciones conducen a que no exista significación estadística cuando se realiza comparaciones entre las notas finales de ingreso y las del examen de admisión.

Published: August 2023

The escalating incidence of bullying cases within Malaysian higher education institutions underscores a disconcerting trend that arises from the confluence of academic pressures, financial strains, relational intricacies, and identity conflicts among students. This unsettling phenomenon engenders not only physical harm and emotional distress but, alarmingly, fatalities as well. In response, the imperative to curtail this deleterious spread through preemptive measures has prompted institutions to engage in student surveys. This research endeavors to illuminate the panorama of bullying perceptions prevailing among students within selected Malaysian higher education institutions. Employing a comprehensive analytical framework encompassing descriptive statistics, crosstabulation, independent samples t-test, and one-way ANOVA, this study scrutinizes the multifaceted dynamics underpinning bullying trends. Employing a combination of convenience sampling and online survey techniques, a cohort of 561 participants was garnered from four distinct higher learning establishments: Universiti Teknologi MARA (UiTM), Universiti Sains Islam Malaysia (USIM), Universiti Sultan Azlan Shah (USAS), and University of Malaya (UM). The outcomes of this investigation delineate a landscape in which bullying remains a persistent concern within the selected higher education institutions. Of particular significance is the perceptual contrast exhibited by bullies as compared to their peers, with the former demonstrating higher levels of support for bullying behavior. Consequently, institutional administrations are impelled to undertake comprehensive initiatives to comprehensively catalog instances of bullying, spanning both psychological and physical manifestations. These findings underscore the gravity of the issue and underscore the urgency for institutions to adopt proactive strategies to mitigate bullying, thereby cultivating environments conducive to holistic student well-being and nurturing scholastic excellence.

Published: August 2023

На основе численного моделирования проведено сравнение эффективности генерации коротких импульсов при когерентной и стандартной пассивной (некогерентной) синхронизации мод с насыщающимся поглотителем, которое показывает преимущество когерентной синхронизации мод по сравнению с режимом стандартной синхронизации мод в лазерах с насыщающимся поглотителем. Когерентная синхронизация мод в двухсекционных лазерах возникает за счет когерентного взаимодействия излучения с поглощающей и усиливающей средами и позволяет генерировать ультракороткие лазерные импульсы длительностью короче времени релаксации поляризации T2 поглощающей и усиливающей сред. В обычных лазерах со стандартной (некогерентной) пассивной синхронизацией мод с насыщающимся поглотителем взаимодействие лазерных импульсов с поглощающей и усиливающей средами некогерентное и длительность генерируемых импульсов всегда ограничена временем релаксации поляризации T2 поглотителя и усилителя. Ключевые слова: пассивная синхронизация мод, когерентная синхронизация мод, самоиндуцированная прозрачность.

Authors: Башмакова Е.Н. , Вашукевич Е.А. , Голубева Т.Ю.
Published: August 2023

To date, two-qubit quantum logic gates have become an essential part of quantum computing. The study of methods for their implementation is an important practical problem for various quantum optical and information applications. In this paper, we have considered a protocol for multimode quantum non demolition interaction between an atomic ensemble and multimode light with orbital angular momentum in order to analyze the applicability of this protocol in discrete variables computing. We have developed a multimode interaction Hamiltonian and analyzed the dynamics of field and atomic variables depending on the structure of the driving field. We discuss in detail the procedure for separating qubit noninteracting subsystems on a set of atomic and field modes for various values of the orbital angular momentum of the driving field. Such a procedure helps to reduce the considered protocol to the parallel evolution of two-qubit closed systems.

Authors: Кузнецова И.А. , Савенко О.В.
Published: August 2023

The problem of electromagnetic H-wave interaction with a layered "insulator-semiconductor- insulator" nanostructure is solved. We assume that the semiconductor layer thickness can be comparable to or less than the charge carrier de Broglie wavelength. Charge carrier surface scattering is taken into account by the Soffer boundary conditions. The electromagnetic wave frequency is less than the plasma resonance frequency. The constant energy surface is an ellipsoid of revolution. Analytical expressions are obtained for the reflection, transmission and absorption coefficients. Calculations are performed for the limiting cases of a degenerate and nondegenerate electron gas. We analyze the dependences of the optical coefficients on dimensionless parameters: the semiconductor layer thickness, the electromagnetic wave frequency and incidence angle, the chemical potential, the ellipticity parameter, the insulating layer permittivities, and the semiconductor-insulator interface roughness parameters.

Effects of Using Websites on Physical Activity and Diet Quality for Adults Living With Chronic Health Conditions: Systematic Review and Meta-Analysis
Authors: Pogrebnoy Dina , Dennett Amy M , Simpson Dawn B , MacDonald-Wicks Lesley , Patterson Amanda J , English Coralie
Published: August 2023

Background

Adults with chronic health conditions need support to manage modifiable risk factors such as physical inactivity and poor diet. Disease-specific websites with health information on physical activity and diet quality may be effective in supporting adults in managing their chronic illnesses.

Objective

The primary aim of this review was to determine whether using websites with health information can lead to improvements in physical activity levels or diet quality in adults with chronic health conditions.

Methods

Randomized controlled trials evaluating the effectiveness of website use on levels of physical activity or diet quality in adults with chronic health conditions were included. MEDLINE, Embase, CINAHL, and the Physiotherapy Evidence Database were searched from the earliest available record until February 2023. Data for outcomes measuring physical activity levels; diet quality; and, where reported, self-efficacy and quality of life were independently extracted by 2 reviewers. The risk of bias was assessed using the Physiotherapy Evidence Database scale, and the overall certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Where values were presented as the same unit of measure, postintervention scores were pooled for meta-analysis to yield an overall mean difference (MD). A standardized MD (SMD) was calculated for the pooled data in which different units for the same outcome were used. Individual trial data were described in cases where the data of trials could not be pooled.

Results

A total of 29 trials (N=6418 participants) across 8 different disease groups with intervention periods ranging from 4 weeks to 12 months were included in the analysis. There was moderate-certainty evidence that using websites with health information increased levels of moderate to vigorous physical activity (MD=39 min/wk, 95% CI 18.60-58.47), quality of life (SMD=0.36, 95% CI 0.12-0.59), and self-efficacy (SMD=0.26, 95% CI 0.05-0.48) and high-certainty evidence for reduction in processed meat consumption (MD=1.1 portions/wk, 95% CI 0.70-1.58) when compared with usual care. No differences were detected in other measures of diet quality. There was no increased benefit for website users who were offered additional support.

Conclusions

The use of websites for risk factor management has the potential to improve physical activity levels, quality of life, and self-efficacy as well as reduce processed meat consumption for adults living with chronic health conditions when compared with usual care. However, it remains unclear whether using websites leads to meaningful and long-lasting behavior change.

Patient-Centered Chronic Wound Care Mobile Apps: Systematic Search and Evaluation by Patients and Physicians (Preprint)
Authors: Dege Tassilo
Published: August 2023

BACKGROUND

Chronic wounds are predicted to increase within the aging population in industrialized countries. Patients experience significant distress due to pain, wound secretions, and resulting immobilization. As the number of wounds continues to rise, their adequate care becomes increasingly costly in terms of health care resources worldwide. eHealth support systems are being increasingly integrated into patient care. However, up to this date, no systematic analysis of such applications for chronic wounds has been published.

OBJECTIVE

The aim of this study is to systematically identify and objectively assess the quality of publicly available mobile apps in German or English for patients with chronic wounds by both patients and physicians.

METHODS

Two reviewers independently conducted a systematic search and assessment of German- or English-language mobile apps for patients with chronic wounds available in the Google Play Store and Apple App Store from April 2022 to May 2022. Three apps met the inclusion and exclusion criteria and were then reviewed independently by 10 physicians using the German Mobile Application Rating Scale (MARS) and the System Usability Scale (SUS). The app with the highest MARS score was subsequently reviewed by 11 patients suffering from chronic wounds, using the German user version of the MARS score (uMARS) and the SUS. Additionally, the affinity for technology interaction (ATI) scale was collected from both patients and physicians.

RESULTS

This study assessed mobile apps for patients with chronic wounds from a pool of 118 identified apps. Out of the 73 apps available in both app stores, 10 were patient-oriented. After excluding apps with advertisements or cost, three apps were evaluated by 10 physicians. Mean MARS scores ranged from 2.64 to 3.88 out of 5, and mean SUS scores ranged from 50.75 to 80.5 out of 100. WUND APP received the highest mean MARS score of 3.88/5 among physicians. Hence, it was subsequently assessed by 11 patients and achieved a similar rating, i.e., a uMARS score of 3.89/5. Technical affinity, measured by ATI, was slightly lower in patients (3.62/6) compared to physicians (3.88/6).

CONCLUSIONS

The quality ratings from physicians and patients were comparable, both indicating mediocre app quality. Technical affinity, assessed using the ATI scale, was slightly lower for patients. Adequate apps for patients with chronic wounds remain limited, emphasizing the need for improved app development to meet patient needs. The ATI scale proves valuable for assessing technical affinity among different user groups.
Effects of Motivational Interviewing and Mindfulness-based Cognitive Therapies on Academic Burnout among Extra-mural Students in Ekiti State
Authors: Joke Fowowe-Ogunmilugba Dr. Bamidele , Animasahun Prof. Rotimi Adebayo
Published: August 2023

Academic burnout is a mental and emotional fatigue state caused by continuous stress among extra-mural students. This syndrome is usually caused by repeated failure and overload of work in the school, which eventually leads to high dropout rate, truancy and failure. Academic burnout hinders academic success of students, as it truncates their advancement in moving to the next academic stage. Previous studies focused largely on predictors of academic burnout of in-school adolescents, while little attention was paid to extra-mural students. This study, therefore, was designed to determine the effects of Motivational Interviewing Therapy (MIT) and Mindfulness-Based Cognitive Therapy (M-BCT) on academic burnout among extra-mural students in Ekiti State, Nigeria. Moderating effects of academic self-efficacy and goal setting were also examined. Pretest-posttest control group quasi experimental design with 3x3x3 factorial matrix was adopted. Three extra-mural centres were randomly selected in Ekiti State, while the simple random sampling technique was used to select participants from each of the remedial study centres. The remedial centres were randomly assigned to MIT (29), M-BCT (51) and control (25) groups, making a total of 105 participants. The instruments used were Academic Burnout Indicator Inventory (for screening – ?=0.92), Maslash Academic Burnout (?=0.70), Academic self-Efficacy (?=0.86) and Goal Setting (?=0.80) scales and instructional guides. Data were subjected to descriptive statistics, Analysis of covariance and Scheffe post-hoc test at 0.05 level of significance. Participants’ age was 22.14±3.15years. The majority of the participants were female (61.5%). There was a significant main effect of treatment on academic burnout of the participants (F(2;84)=140.13. partial ?2=0.77). The participants in the control group (111.04) had the highest mean scores on academic burnout, followed by the M-BCT (88.20) and the MIT (61.59) groups. There was no significant main effect of academic self-efficacy and goal setting on academic burnout. There was a significant interaction effect of treatment and goal setting on academic burnout (F(2;84) =3.93, partial ?2=.16), in favour of the participants with high goal setting from the MIT group. Motivational interviewing and mindfulness-based cognitive therapies reduced academic burnout among extra-mural students in Ekiti State, Nigeria. Counselling psychologists and other help professionals should adopt these therapies.
The Complexity of Climate Positions of Right-wing Populist Parties in Europe
Authors: Delin Li
Published: August 2023

The rise of anti-climate right-wing populist parties urgently threatens mainstream climate governance goals in Europe. However, it is an oversimplification to portray all right-wing populist parties as outright climate deniers. In reality, the climate positions of right-wing populist parties are complex. While some right-wing populist parties continue to deny climate science and oppose climate action, others acknowledge the evidence but distance themselves from mainstream climate policies. This complexity arises from the tension between these parties’ ideological convictions and strategic considerations. On the optimistic side, the complexity of right-wing populist parties’ climate positions could create openings for cross-party cooperation based on scientific consensus and help transform some right-wing populist parties into constructive actors on climate governance. However, most right-wing populist parties remain deeply hostile to climate action; it is hard to expect that the opportunism of such parties in their climate positions will prompt them to make real policy concessions.
Teología y literatura
Authors: Aravena Aravena Soledad , Sánchez-Echeverría Lorena , Uribe Ulloa Pablo
Published: August 2023

The question about access to God seems to have no answer from the scientific experimental method. So, it is necessary to open up to the possibility of a new methodology for expanding the boundaries of reason and access to the knowledge of God by means of a more human language. Thus, a literature review made it possible to establish that theology relies on a method to approach truth. This method goes beyond the boundaries of positive sciences, integrating theological-literary dialog and theological work. This is evident in the work of Olegario González de Cardedal since it emphasizes the dialogical character of theology, in which God reveals Himself through Word, thus recognizing a great richness for theological reflection in the encounter with literary language.

Redes neuronales de apoyo en la docencia bajo Moodle para predicción de deserción y reprobación escolar
Authors: Alayola Sansores Alejandro
Published: August 2023

Artificial Intelligence (AI) designs computer tools that simulate human intelligence processes, including learning, reasoning, and selfcorrection.
In the educational field, AI facilitates the evaluation of student progress thro ugh neural networks that adjust tests to previously achieved achievements. The purpose of this work was to design an Artificial Neural Network (ANN) that will analyze the performance of students in the subject of Biomedical Informatics I at the Facultad de Medicina of the UNAM in order to estimate the probabilities of passing, failing, and dropping out.
Materials and methods: A neural network was designed in Python, consisting of 3 fully connected layers, using performance information from approximately 2000 students in the Moodle platform for Biomedical Informatics I during 2019, 2020, and 2021 at the Facultad de Medicina of UNAM. The neural network was trained to estimate the probable performance of the students, executing 2500 epochs with a mean absolute error level of 0.0158. A kappa accuracy rate of 0.947 was obtained through a confusión matrix when classifying between passing and failing grades. For visualization, a web system with a traffic light system was designed to allow evaluation and teaching coordinators from the Department of Biomedical Informatics to consult the results obtained from the network.
Discussion: The network must continue to be fed with controlled data, meaning data that is specifically worked for the network’s training, since the quality of the data in the input directly determines the quality of the data obtained at the end of the process, affecting the network’s objective attainment.
Conclusion: There is still much to learn and work to be done, but the interdisciplinary effort will allow us to improve our system and ultimately support the educational process of future doctors in the best way possible.

Data Leak Localization and Prevention using LDN
Authors: . Munikrishnan
Published: August 2023

Abstract: While geofencing and geolocation tracking offers valuable tools for data sharing and access, it is crucial to acknowledge their potential risks and concerns. Some individuals may feel uneasy about the constant tracking and monitoring of their location, which can give rise to privacy issues. Moreover, geofencing and geolocation tracking are susceptible to hacking and cyber attacks, potentially leading to the theft or compromise of sensitive data. To address these concerns, businesses, and organizations must implement robust security measures and protocols when employing geofencing and geolocation tracking. These measures may involve encrypting sensitive data, monitoring and auditing access logs to identify potential threats or unauthorized access, and implementing user authentication and access controls to restrict data and information access. In conclusion, while geofencing and geolocation tracking can be powerful tools for data sharing and access, they should be utilized cautiously and accompanied by strong security measures to mitigate potential risks and threats.
Enhancing Data Security and Predictive URL Analysis: A Comprehensive Approach to Preventing Data Breaches
Authors: Sreerambabu Dr. J.
Published: August 2023

Abstract: There has never been a time in history when starting and running a profitable business has been more difficult due to the upward trending rising trend in data breaches. Data breaches can have an immediate impact on hundreds of millions or conceivably billions of individualities in the data-driven world of the moment. Data breaches have grown in scope along with digital metamorphosis as attackers take advantage of our every data. Various measures are taken by many companies to control data breaches in order to prevent them. A business or firm may employ techniques like data encryption, human error, data backup and recovery, and data security software. In the case of middle-level and low-level organizations suffering the most cyber-attacks, Many businesses are successful in defending their data from intruders, typically large multinational corporations which engage a specialist and safeguard their own data.

Abstract: The expanding aquaculture sector can greatly benefit from having access to comprehensive fish information, which includes data on ecosystems, food requirements, and related details. Relational databases play a crucial role in storing the diverse range of fish species data in the aquaculture industry. However, due to the extensive variety of species and their associated data, organizing and categorizing this information can be a challenging task. Nonetheless, fishermen can derive significant advantages from visual representations of the data and a recommendation system that suggests the most suitable fish species and optimal ecological conditions. By leveraging data on fish species, names, taxonomy, and survival characteristics, a connected user can receive personalized recommendations based on their interests. The proposed system also offers appropriate food variety suggestions for the fish, ensuring scalability and effective generation of recommendations. Through the integration of information from multiple sources, a database system can efficiently process, manage, store, and retrieve relational data. Furthermore, implementing the linear discriminant algorithm enhances the accuracy and speed of food recommendations for fish.

Abstract: The rate of population growth in the world is alarming. It is quite difficult to meet the needs of such a large population. Good nutrition is the most fundamental requirement for each human being. The old and conventional farming techniques, however, are proving insufficient for supplying food in large amounts due to the growing population. Fortunately, by utilizing cutting-edge agricultural techniques and smart electronics technology, we can raise efficiency and productivity to higher levels. Additionally, this will guarantee us access to food. An IOT-based smart agriculture monitoring system project using Arduino is presented to improve the effectiveness and productivity of agricultural crops. One of the most crucial aspects of our society is agriculture. Every day, farmers generate food. Water is a key aspect of successful agriculture. Technology has played a crucial role in developing agriculture. The world's largest water user is the agriculture industry. Since water is used so extensively in agriculture, which makes up the majority of the Indian economy, it is disappearing day by day. One answer to this issue is irrigation, as plants are fed with water by drip irrigation. Water is well conserved by irrigation. The agricultural land must be consistently watered while being continuously monitored. In many parts of the world, manual irrigation is still used to deliver water for agriculture.

Abstract: In recent years, cyber security incidents have occurred frequently. In most of these incidents, attackers have used different types of spam email as a knock-on to successfully invade government systems, well-known companies, and websites of politicians and social organizations in many countries. The detection of spam mail from big email data has been paid public attention. However, the camouflage technology of spam mail is becoming more and more complex, and the existing detection methods are unable to confront the increasingly complex deception methods and the growing number of emails. In this project, we proposed to design a novel efficient approach named Spam Spoiler for big email data classification into four different classes: Normal, Fraudulent, Harassment, and Suspicious E-mails by using LSTM-based GRU. The new method includes two important stages, the sample expansion stage and the testing stage under sufficient samples. This project the LSTM-based GRU efficiently captures meaningful information from E-mails that can be used for forensic analysis as evidence. Experimental results revealed that Spam Spoiler performed better than existing ML algorithms and achieved a classification accuracy of 98% using the novel technique of LSTM with recurrent gradient units. As different types of topics are discussed in E-mail content analysis. Spam Spoiler effectively outperforms existing methods while keeping the classification process robust and reliable.

Abstract: Cyber bullying refers to the use of electronic techniques of intimidation. Historically challenging, there has been a growing awareness of the repercussions for young people. Teenagers and young adults who spend time on social media sites are an easy target for bullies because of the platform's conducive nature to harassment and threats. We can create algorithms that can automatically identify cyberbullying material and distinguish between the language styles of cyberbullies and their victims with the use of machine learning techniques. Over the last decade, social media has seen explosive growth, which has benefits and drawbacks. As the number of social media sites and apps continues to grow, more and more people are able to connect with one another online. directly, ignoring cultural and economic contexts While there are numerous positive outcomes associated with social media use, none exist at this time. The increase of hate speech over the last several years is a special issue that has surfaced. The use of foul language is the major component of hateful statements. Online networking use It might be used to refer to anybody or anything at all. collective of like-minded people. The methods we use to deal with hostility and the steps we take to mitigate it were detailed in this study. People's instantaneous expressions of wrath and animosity on social media are harmful to the sentiments of others. In-depth investigation on the handling of The most accurate machine learning and natural language processing techniques were used to choose the model used to exclude hate speech.

Penyakit busuk pangkal batang (BSR) yang disebabkan oleh jamur Ganoderma sp pada tanaman kelapa sawit masih menjadi penyakit utama dan belum ada tindakan pengendaliannya yang efektif. Perlakuan kultur teknis untuk memperpanjang umur tanaman masih menjadi tindakan utama dalam pengendalian penyakit BSR ini. Ketepatan identifikasi dan klasifikasi tanaman sehat dan terinfeksi penyakit BSR secara cepat dan tepat sangat diperlukan untuk mendukung perlakuan kultur teknis. Penelitian ini melanjutkan penelitian Santoso (2020) untuk identifikasi dan klasifikasi tanaman kelapa sawit sehat dan terinfeksi penyakit BSR dengan menggunakan pendekatan remote sensing dari image yang direkam oleh kamera multispektral tiga band dan machine learning. Tujuan utama dari penelitian ini adalah meningkatkan akurasi interpretasi tanaman sehat dan terinfeksi penyakit BSR dengan penambahan variabel berupa sepuluh indeks vegetasi yang memanfaatkan ketiga band dari kamera multispektral (merah, hijau, dan near infrared/NIR) dan penerapan enam belas machine learning classification model. Hasil penelitian menunjukkan model random forest dan stochastic gradient boosting mampu meningkatkan akurasi interpretasi menjadi 87.18 % dari 79.49 % dan kappa value menjadi 0.69 dari 0.48. Peningkatan akurasi ini tidak lepas dari variabel penting dalam fiting model yang digunakan dalam penelitian ini yang didominasi oleh variabel dari indeks vegetasi dan band merah. Model ini perlu diuji untuk mengidentifikasi tanaman sehat dan terinfeksi penyakit BSR dengan taraf insidensi rendah dan sedang.

La cartilla para la lectoescritura de la lengua emberá de los resguardos de Cuti y Citará es producto de un trabajo investigativo suscrito en el convenio entre la Universidad de Antioquia y el ICANH entre los años 2018 y 2019. Durante este tiempo los participantes del proyecto se trasladaron a las diferentes comunidades vinculadas en la construcción del actual Parque Arqueológico e Histórico Santa María de la Antigua del Darién —ubicado en la vereda Santuario del corregimiento de Unguía en el Chocó— para contribuir en los proyectos e ideas que expresan las comunidades. Es así como se toma la decisión de construir una recopilación escrita, con el objetivo de documentar la lengua, la cultura y los símbolos que perviven desde la tradición oral, pero que carecen de métodos para aprender sobre cómo se escribe y se lee aquello que se quiere conservar. Para lograr la cartilla, se construyó un plan pedagógico de trabajo que permitió conducir y dinamizar el proceso de la mano de las maestras —hablantes castellanas—, se contó con la presencia de la comunidad y con la participación activa de líderes como Antonio Chamarra y María Guasarupa, quienes aportaron valiosos elementos en las reflexiones, la recolección, la sistematización y la corrección del material que se presenta en esta cartilla.
Aproximación histórica al acto de producción del Catecismo de fray Dionisio de Sanctis (1577): entre identidad y mentalidades
Authors: Marín Tamayo John Jairo , University Laurentian
Published: August 2023

La evangelización de los habitantes del Nuevo Mundo exigió no solamente una gran cuota de misioneros, sino también la producción de abundantes herramientas catequísticas para la instrucción de los denominados “naturales de Indias”. Este estudio es una aproximación histórica al acto de producción del Catecismo y Cartilla de fray Dionisio de Sanctis (1577), medio con el cual se pretendía homogeneizar y establecer una manera más eficaz de instruir a los indígenas del obispado de Cartagena de Indias y, de este modo, revertir los escasos resultados obtenidos, hasta ese momento, en su conversión. Se aborda el Catecismo no solamente como una herramienta catequística, sino también como un producto cultural que transmite, en parte, las mentalidades de su autor y de su época. De hecho, se pudo determinar que el Catecismo fue redactado para contribuir a la construcción de la identidad del indígena colonial colonizado —vasallo sujeto a la Corona española y cristiano católico fiel a Roma— y a la instauración de una mentalidad colonial en la región. El estudio desvela el tipo de instrucción que se pretendía ofrecer a los indígenas del obispado de Cartagena de Indias, las estrategias utilizadas para adaptarla a la condición de estos y la pertinencia de la enseñanza de la doctrina en castellano, aspectos que permiten acceder a la visión social, pedagógica, antropológica, teológica y eclesial priorizada por el autor.
