Background:

Cancer is a life-threatening disease prevalent worldwide, but its proper treatment has not yet been developed. Conventional therapies, like chemotherapy, sur-gery, and radiation, have shown relapse and drug resistance. Nanomedicine comprising cancer theranostics based on imaging probes functionalized with polymeric nanoconjugates is acquir-ing importance due to its targeting capability, biodegradability, biocompatibility, capacity for drug loading, and long blood circulation time. The application of synthetic polymers contain-ing anti-cancer agents and functionalizing their surface amenities with diagnostic probes offer a nano-combinatorial model in cancer theranostics.

Objective:

This study aimed to highlight the recent advancements in quantum dots-functionalized nanoconjugates and substantial progress in advanced polymeric nanomaterials in cancer theragnostics.

Methods:

This review details the synthetic methods for fabricating Quantum Dots (QDs) and QDs-functionalized polymeric nanoparticles, such as the hydrothermal method, solvothermal technique, atomic layer desorption, electrochemical method, microwave, and ultrasonic method.

Results:

Conjugating nanoparticles with photo-emitting quantum dots has shown efficacy for real-time monitoring and treating multi-drug-resistant cancer.

Conclusion:

Quantum dots are used in phototherapy, bioimaging, and medication delivery for cancer therapy. Real-time monitoring of therapy is possible and multiple models of hybridized quantum dots may be created to treat cancer. This review has discovered that numerous at-tempts have been made to conjugate carbon and graphene-based quantum dots with various biomolecules.

Authors: Sun Qiang , Tong Ruinian , Li Yiqing , Wang Yu , Fang Feng , Jin Xionghua , Zhang Min , Xu Steven , Lei Run , Fan Pengcheng
Published: September 2024

Background:

Atypical peaks were observed in capillary electrophoresis with sodium
dodecyl sulfate (CE-SDS) during the development of therapeutic monoclonal IgG4 antibodies
(mAb-X). Based on the previous literature reports, the atypical peak may be caused by various factors
such as post-translational modifications (PTMs), method-induced artifacts, sample degradation
and sequence variants. Due to the high complexity structure of mAbs and the limitations of
CE-SDS, acquiring comprehensive profiling of atypical peaks has historically been challenging.

Objective:

Here we developed a strategy utilizing complementary analytical methods to identify
the cause of atypical peak.

Methods:

This strategy includes optimizing reduced CE-SDS method to evaluate artifacts induced
by the analytical method, excluding potential glycation modifications, and utilizing Liquid Chromatograph
Mass Spectrometer (LC-MS) to characterize mAb-X.

Results:

Our study demonstrates that the atypical peaks of mAb-X are a mixture of method-induced
artifacts and variants in the C-terminal extension sequence of the light chain.

Conclusion:

Strategy for complementary analytical methods tools helps to identify the cause of
unknown species and plays a key role in product and process characterization.

Authors: Darvishi Mohammad , Rafsanjani Seyed Mahmoud Reza Hashemi , Nouri Majid , Abbaszadeh Saber , Heidari-Soureshjani Saeid , Kasiri Karamali , Rahimian Ghorbanali
Published: September 2024

Background:

Clostridium difficile is an opportunistic infection that can lead to antibi-otic-associated diarrhea and toxic megacolon.

Objective:

This systematic review study aimed to investigate polyphenols' antibacterial and anti-toxin properties and their effects on reducing complications related to C. difficile Infections (CDI).

Methods:

This systematic review was conducted following the PRISMA guideline 2020. Multiple databases, including Web of Science, PubMed, Cochrane Library, EMBASE, and Scopus, were searched thoroughly for existing literature. After considering the inclusion and exclusion criteria for the review, 18 articles were included. Data were collected and registered into an Excel file for further investigations and conclusions.

Results:

Polyphenols by reducing Reactive Oxygen Species (ROS) levels, increasing inflammatory factor Interleukin 10 (IL-10), reducing Nuclear Factor kappa B (NF-κB) and Tumour Necrosis Fac-tor-α (TNF-α), IL-6, IL-1α, IL-1β, Granulocyte Colony-stimulating Factor (G-CSF), and Monocyte Chemoattractant Protein-1 (MCP-1) and Macrophage Inflammatory Protein-1 alpha (MIP-1α) lev-els, and regulating the expression of Bcl-2 and Bax, make the growth and replication conditions of C. difficile more difficult and prevent it from producing toxins. Furthermore, polyphenols can ex-hibit prebiotic properties, promoting the growth of beneficial Bifidobacterium and Lactobacillus species and consequently regulating gut microbiota, exerting antimicrobial activities against C. dif-ficile. They also induce their beneficial effects by inhibiting the production of C. difficile TcdA and TcdB.

Conclusion:

Polyphenols have been reported to inhibit C. difficile growth and toxin production by several mechanisms in preclinical studies. However, more clinical studies are needed to investigate their safety in humans.

Published: September 2024

aims:

In this work an attempt was made to join aluminium alloy with the steel utilizing the friction stir welding process. During FSW, the tool travels through the propagation and dispersion of heat input per unit distance.

background:

Therefore, the quantity of heat input per unit of weld length is influenced by traversal speed. Heat is created because the tool spends less time spinning at extremely fast traversal speeds.

objective:

The materials are incorrectly mixed and compacted as a result, which reduces their strength. When the tool was moving rapidly, it generated enough heat at the right temperature to encourage grain growth and strain relief, increasing the impact strength of the joint.

method:

Micro-hardness varies over a distance in different zones depends on the grain size and phases underneath each depression. Micro-hardness often rises as a result of grain refining brought on by tool rotation in the SZ and TMAZ.

result:

But as the indentation distance from the SZ grows, the micro-hardness declines, especially in the HAZ and the BM's grain-coarsened region.

conclusion:

The distribution of micro-hardness also shows that dynamic recrystallization in the FSW leads to considerable grain refinement in the SZ. SZ is hence harder on the microscale than BM and HAZ.

other:

The various mechanisms such as climb, cross-slip and annihilation, causes rearrangement of dislocations and results in the formation of low angle grain boundaries and development of sub-grains were observed in micrograph.

High economic growth and increased spending on social assistance and education spending still causes relatively high levels of poverty in the Districts/Cities of East Java Province in 2013-2022. Therefore, the aim of this research is to analyze and determine the influence of economic growth, social assistance spending, and education spending on poverty in the Districts/Cities of East Java Province. The type of data used is panel data from 38 districts/cities for ten years using the panel data regression analysis method. The research results show that social assistance spending has a negative and significant effect on poverty, education spending has a negative and significant effect on poverty, and economic growth has a positive and significant effect on poverty. This is because the capital-intensive sector is growing more rapidly than the labor-intensive sector. So, the government needs to make efforts to increase employment-based sectors and be able to absorb more workers, especially in capital-intensive sectors which make a greater contribution to economic growth in the districts/cities of East Java Province.

Assessing the Influence of ESG Factors on Stock Prices: An Analysis of Nifty 50 Companies
Authors: Shrimal Kapil , Kumar Sunil , Shukla Aastha
Published: September 2024

This study examines the relationship between sustainability reporting, stock performance, and ‘Environmental’, ‘Social’, and ‘Governance’ (ESG) characteristics of Indian companies. The goal is to clarify the influence of environmentally conscious activities on enterprises. This research addresses the lack of knowledge regarding the impact of ESG ratings on stock performance in the Indian market, which has been overlooked in previous studies that mostly focused on the US and European markets. The study employs a quantitative methodology to gather stock prices and ESG ratings for companies in the Nifty 50 index. It then constructs portfolios that reflect the companies with the greatest and lowest ESG scores. The data is examined by OLS regression and Pearson correlation tests, indicating that ESG has a detrimental effect on stock prices in India. This suggests that enhancing ESG scores may not be advantageous for firms. Nevertheless, the study reveals disparities between companies with high and low ESG scores in relation to Sustainable Development Goals (SDGs), regulatory frameworks, anti-corruption initiatives, and ESG methodology. This presents opportunities for Indian businesses to improve their sustainable practices and generate value for stakeholders.
Cocreation of a Video Feedback Tool for Managing Self-Care at Home With Pairs of Older Adults: Remote Experience-Based Co-Design Study
Authors: Strandberg Susanna , Ekstedt Mirjam , Fagerström Cecilia , Backåberg Sofia
Published: September 2024

Background

Involving older adults in co-design processes is essential in developing digital technologies and health care solutions to enhance self-care management at home, especially for older adults with chronic illness and their companions. Remote co-design approaches could provide technologically sustainable solutions that address their personal needs.

Objective

This study aimed to cocreate and test the usability of a video feedback tool to facilitate self-care management at home.

Methods

This experience-based co-design approach involved collaboration between 4 pairs of older adults, 4 researchers, and 2 service designers in three steps: (1) six iterative workshops (5 remote and 1 in person) to cocreate self-care exercises within an existing video feedback tool by identifying factors influencing self-care management; (2) developing and refining the self-care exercises based on suggestions from the older adults; and (3) usability testing of the cocreated exercises with the 4 pairs of older adults in their homes. Among the older adults (68-78 years), 3 adults had heart failure and 1 adult had hypertension. Data were analyzed inductively through thematic analysis and deductively using the USABILITY (Use of Technology to Engage in Adaptation by Older Adults and/or Those With Low or Limited Literacy) framework.

Results

The identified influencing factors guiding the contents and format development of 2 new self-care exercises were that pairs of older adults support and learn from each other in performing self-care, which increases their motivation and engagement in practicing self-care at home. The usability test of the 2 new self-care exercises, “Breathing exercises” and “Picking up from the floor,” revealed that the pairs found the exercises and the video feedback component valuable for learning and understanding, for example, by comparison of performances highlighting movement variability. However, they found it difficult to manage the video feedback tool on their own, and a support structure or tailored education or training was requested.

Conclusions

This study emphasizes that the video feedback tool holds the potential to facilitate learning and understanding in self-care management, which may support motivation. The studied video feedback tool can be beneficial for pairs of older adults managing self-care at home as a complement to traditional health care services, but an accurate supporting structure is required. The effectiveness of the video feedback tool and its integration into existing health care services still need to be assessed and improved through careful design and structured support.
Mental Health Providers’ Comfort in Prescribing Over Telemedicine: Content Analysis of Challenges and Solutions (Preprint)
Authors: Ivanova Julia , Cummins Mollie R , Soni Hiral , Ong Triton , Bunnell Brian E , López Esteban , Welch Brandon M
Published: September 2024

BACKGROUND

In response to the COVID-19 pandemic, the U.S. extended regulatory flexibilities to make telemedicine more accessible to providers and patients. Some of these flexibilities allowed providers to in-take patients over telemedicine and prescribe certain scheduled medications without an in-person visit.

OBJECTIVE

We aim to understand providers’ parameters for their comfort in prescribing over telemedicine and report on solutions providers have adopted in answer to potential barriers and challenges in prescribing via telemedicine.

METHODS

As part of a larger mixed-method study between February and April 2024, we conducted 16 semi-structured interviews with mental health providers who prescribe via telemedicine. We used the results of a web-based, cross-sectional survey to develop a codebook and support recruitment. We analyzed a subsection of the 16 interviews using content analysis to capture comfort, barriers, and workarounds in telemedicine prescribing. We reported codes by frequency and by provider.

RESULTS

Participants were typically male (11/16), provided care mostly or completely over telemedicine (11/16), and were psychiatrists (8/16) or other physician (3/16). The content analysis yielded a total of 234 codes with three main codes–comfort (n=98), barriers or challenges (n=85), and workarounds or solutions (n=27)–and two subcodes–uncomfortable prescribing (n=30) and comfortable prescribing (n=68) over telemedicine. Participants reported being comfortable prescribing over telemedicine as long as they could meet their main parameters of working within their expertise, having access to needed patient health information, and being compliant with rules and regulations. Participants reported frustrations with e-prescription workflows and miscommunications with pharmacies. Solutions to ease frustrations and alleviate discomforts in prescribing over telemedicine included developing workflows to help patients complete labs and physical exams and directly communicating with pharmacies.

CONCLUSIONS

By applying content analysis to the semi-structured provider interviews, we found that physicians are comfortable prescribing via telemedicine when they feel they are practicing within their personal parameters for safety. While many providers experience frustrations such as miscommunication with pharmacies, these barriers do not prevent them from telemedicine prescribing. With expected changes in 2024 to the U.S. laws and regulations for telemedicine prescribing, we may see changes in provider comfort in prescribing.
Machine Learning Prediction Models for Recovery After Colorectal Cancer Surgery Using Wearable Device Data, Air Quality Data, and Clinical Evaluation Data (Preprint)
Authors: Wu Chia-Tung , Su Kai-Zheng , Hsieh Tsung-Ting , Jhao Lian-Yin , Liao Yu-Tso
Published: September 2024

BACKGROUND

With the advancement of medical technology, minimally invasive surgery has gradually replaced traditional surgery as the primary treatment for colorectal cancer because of its more minor wound and shortened length of hospitalization. The subject of our research is how to investigate the postoperative recovery status further on this basis.

OBJECTIVE

The study hopes to use the physiological and clinical data combined with the patient's lifestyle indicators and use machine learning models to predict the patient's postoperative recovery.

METHODS

A total of 85 patients, data had been collected from National Taiwan University Hospital and National Taiwan University Hospital Hsinchu Branch, undergoing minimally invasive surgery for colorectal cancer. We use wearable devices to collect the participant's step count data, select the nearest station according to their location to collect the PM2.5 in the air quality index of the day as environmental data and merge the two lifestyle indicators above with physiological and clinical data to predict. We use postoperative complications, defined by the Clavien-Dindo classification, as the basis for judging the situation of postoperative recovery. Four data pre-processing methods and six machine learning classification models were used to predict, and each feature was discussed in an interpretable model SHAP.

RESULTS

In each data set and machine learning model, the performance of the third data set trained with Random Forest and the performance of the fourth data set trained with XgBoost are better. Based on the results, we found that the model tended to predict a good recovery on the participants with more steps/day than 2,000 and low sub-index of PM2.5 in their living environment.

CONCLUSIONS

Combined with the patient's physiological and clinical data, step counts, and air quality data, through the data pre-processing, machine learning prediction, and interpretable model analysis, the merged data are used to classify the participants' postoperative recovery status. We found that if the patient had a daily essential exercise (based on the number of steps, more than 2,000 steps per day) in an environment where PM2.5 is low (PM2.5 sub-index is less than 36), it would help Postoperative recovery.
A Study on the Subtitle Translation of Farewell My Concubine from the Perspective of Relevance Translation Theory
Authors: Ma Yuanyuan , Shi Shi
Published: September 2024

The subtitle translation of film and television works has been an important topic in the field of translation research because of its great market demand and its significance in cultural communication. The subtitle translation strategy of Farewell My Concubine, a world-renowned Chinese movie, has been studied by scholars in China, but no one has yet explored the contextual effects, information relevance and audience information processing efforts of its subtitle translation in relation to Relevance Translation Theory. A translation achieves optimal relevance when it enables the viewer to discover the meaning intended by the lines without effort and the meaning conveyed is worth the effort of the audience to achieve the appropriate effect. Based on the English translations of film clips by the MTI students in the Class of 2022 of the School of Foreign Languages at Hubei University of Technology, this paper analyses how different English translation strategies affect information transmission, contextual presuppositions, readers' reactions, and the artistic effect of the film in the light of Relevance Translation Theory. Finally, the paper summarizes the students' translation problems and draws lessons from this practice, aiming to contribute to the progress of subtitle translation in China, especially for cultural and artistic films.

Authors:   Clarkson University, Monroe Stephen E. , Wang Junfeng ,   Simerics Inc, Liang Chunlei ,   Clarkson University
Published: September 2024

In this study, an Unsteady Reynolds-Averaged Navier-Stokes (URANS) model is demonstrated its suitability for studying the flow and performance of open marine propellers and waterjet pumps. First, the accuracy of the URANS model is validated by studying turbulent flow past counter-rotating propellers (CRPs). Specifically, experimental data from Miller (1976) is employed for comparison against the URANS results. Subsequently, URANS is used to study the flow and performance of an Office of Naval Research (ONR) axial flow waterjet pump (AxWJ-2). Due to the large number of degrees of freedom for both simulations, parallel computations over 80 cores are performed. For the CRP study, torque and thrust coefficients are assessed against a range of advance ratios, ensuring a Reynolds number of less than 600,000. For the waterjet, torque and head coefficients are computed for a range of flow rates at a Reynolds number of 1.25 million. For both studies, two levels of mesh resolution are utilized. The finer meshes of both studies contained roughly four times the total number of cells employed in their respective coarser counterparts. These refinements lead to minor improvements, suggesting good grid resolutions with the coarser grids. Across all advance ratios for the CRP set, the URANS torque and thrust coefficients show good agreement with experimental results, remaining within 10% difference. The torque and head coefficients for the waterjet displayed even better agreement, with the greatest error across all flow conditions remaining under 3%. Moreover, URANS studies revealed that the stator is responsible for 20% of the waterjet’s power production.

La Política de Cuidado como pilar de una recuperación transformadora: sostenible, justa e igualitaria
Authors: Bárcena Ibarra Alicia Isabel Adriana
Published: September 2024

Este trabajo aborda la importancia de los cuidados en la sostenibilidad de la vida, y en particular la necesidad de implementar Políticas de Cuidado no solo como un elemento clave en la recuperación con igualdad de esta crisis, sino como pilar fundamental de un cambio paradigmático hacia un nuevo estilo de desarrollo. En este sentido, se sostiene que es necesario fortalecer el rol de los Estados desde una perspectiva feminista a través de políticas y sistemas de cuidados universales, intersectoriales e integrales, con el fin de modificar la actual distribución del poder, los recursos y el tiempo entre mujeres y hombres. De esta manera, el diseño de políticas de cuidados se constituye en un eje crucial en el tránsito hacia una sociedad que priorice el cuidado de las personas, del planeta y el autocuidado. Este trabajo tiene por finalidad exponer la importancia de los cuidados en la sostenibilidad de la vida, y en particular la necesidad de diseñar e implementar políticas y sistemas de cuidado no solo como un elemento clave en la recuperación con igualdad de esta crisis, sino como pilar fundamental de un cambio paradigmático, que modifique la injusta división sexual del trabajo, la cual constituye un nudo estructural de la desigualdad de género y limita la autonomía de las mujeres. El trabajo se organiza de la siguiente manera: en primer lugar, se exponen los efectos de la crisis desencadenada por la pandemia de la COVID-19 sobre los nudos estructurales de la desigualdad de género en América Latina y el Caribe; en segundo lugar, se definen las políticas y los sistemas de cuidado, y se presentan aquellos factores que constituyen elementos centrales de estas políticas; finalmente, se expone el avance en acuerdos y en la agenda internacional y regional relativa a los cuidados.
Mujeres ex-céntricas y cuidados: exploraciones desde la ruralidad mexicana transfronteriza
Authors: Martínez Ruiz Diana Tamara , Vargas Silva Alethia Danae , González Lázaro Martha
Published: September 2024

La pandemia por la COVID-19 puso de cabeza el orden de la vida social de todo el mundo. La crisis generalizada incitó una reflexión sobre las normas y los valores que rigen a las sociedades, condujo a nuevas percepciones sobre la vida, la salud, el trabajo y el cuidado. Este último se comenzó a ver como un valor en sí mismo y como una tarea fundamental para el bienestar de la sociedad. Concebirlo de esta forma nos llevó a diversas académicas a reflexionar en torno a la distribución de las tareas de cuidados. Como ha revelado el pensamiento feminista desde sus años primarios, la distribución del cuidado es desigual y se determina por razones de clase, etnia, sexo, género y un sinnúmero de condiciones socioculturales que determinan la interseccionalidad en los sujetos sociales. Así, las concepciones y distribuciones de las tareas de cuidados varían en cada contexto de vida social y comunal y se han manifestado diferenciadamente ante la pandemia por la COVID-19. este libro muestra una mirada interseccional del cuidado, poniendo especial énfasis en la variable de género. El presente estudio plantea una reflexión sobre el concepto de cuidados, atravesado por el contexto pandémico. Las investigadoras que construimos este trabajo proponemos partir de que el cuidado se entiende y ejerce desde diferentes concepciones que llamamos subjetividades compartidas o imaginarios colectivos. Son estructuras de pensamiento, ordenamientos determinados por las condiciones geográficas, culturales y normativas de las unidades comunales. Este documento se basa, entonces, en la exploración de la dimensión colectiva del cuidado. Recorre su aspecto social, familiar –el cuidado como custodia– e individual, comprendiendo este último como autocuidado. Por ello, nos aproximamos a estas dimensiones desde tres momentos: las condiciones previas a la pandemia, las estrategias que se generaron durante la pandemia –en el momento del confinamiento más estricto– y las formas de cuidado en la “nueva normalidad”. Este trabajo pone en evidencia las diferencias en las dinámicas de cuidados durante estos tres momentos en los distintos contextos socioculturales observados. Nos interesamos por estudiar contextos ex-céntricos, que están situados al borde de la hegemonía, revelando los diferentes matices del confinamiento por la COVID-19 en la humanidad.

Published: September 2024

Introducción y debate El objetivo de este texto es señalar las reacciones institucionales y de los actores sociales y políticos ante la pandemia por COVID-19 en los países de la región, así como su impacto en la democracia durante el ciclo electoral, en la relación entre ciudadanos y la política, a sabiendas que las decisiones tomadas a lo largo de la pandemia pueden tener una relevancia semejante a la que desencadenó el crack de 1929, la crisis del petróleo de 1973 o la deuda de 1982. Puede afirmarse que en 2020 se está creando una coyuntura crítica que genera una situación de incertidumbre donde las decisiones de los actores políticos, sociales y económicos más relevantes de cada país son cruciales y decisivas para el desarrollo político e institucional en el mediano y largo plazos. El análisis de las coyunturas críticas es deudor de las teorías de path dependency (teoría de la dependencia del camino), de acuerdo con los arreglos políticos e institucionales establecidos en un determinado momento se afianzan debido a su capacidad para dar forma a incentivos, visiones del mundo y recursos de los actores y grupos afectados por unas circunstancias excepcionales (Capoccia, 2015). Dicho libro, tiene como objetivo analizar cuál ha sido el impacto de la pandemia COVID-19 en 19 países que conforman América Latina continental además de Cuba y República Dominicana. Antes de abordar el análisis país a país, esta introducción señala algunas cuestiones generales que son relevantes para la comprensión del estudio. El trabajo parte de que la crisis sanitaria ha representado una coyuntura crítica en la medida que ha generado una situación de incertidumbre donde las respuestas de los actores políticos, sociales y económicos más relevantes de cada país han sido decisivas para el desarrollo político e institucional posterior.

Eggshell is a waste generated in high quantities worldwide and can be exploited since it is a rich source of Ca. It is estimated that it contains about 94 to 96% of CaCO3 and through a thermal process can be transformed into CaO, and this is an efficient precursor for the synthesis of hydroxyapatite (Ha), which is a biomaterial and due to its biological properties has been the subject of multiple studies of great importance in different branches of biomedicine. The purpose of this paper was to synthesize bio-based Ha from eggshells, using the precipitation method, eliminating the addition of NH4OH, used in the traditional synthesis, and making the washes with citric acid. The eggshells, CaO obtained, and bio-based Ha were characterized by FTIR-(ATR), XRD, and TGA, thus demonstrating the functional groups, crystalline structure, and thermal stability of each material. MTT assay on NIH-3T3 fibroblast cell line indicated that viability in each of the materials is not affected at differentconcentrations (50, 100, and 200 μg/mL), as well as with modification in Ha synthesis. The biobased Ha presented cell viability of 110.7 % at a concentration of 200 μg/mL. Hence, the synthesized Ha shows potential for use in wound healing.

Es necesario entender el fenómeno de la globalización para explicar la liberalización de los mencionados servicios y su reestructuración a partir de los lineamientos establecidos por la OMC. Este ensayo se propone como objetivo analizar el sector de los servicios financieros mexicanos en el marco de la Organización Mundial de Comercio, a la luz de los diversos tratados de libre comercio que México ha suscrito. La autora explica que el sistema financiero constituye una infraestructura básica de la economía de un país, motivo por el cual se requiere de una reglamentación cautelar que permita mayor liberalización de este sector, dentro del contexto de la globalización. En este sentido, la meta sería generar un entorno que proporcione seguridad jurídica para alcanzar los beneficios de la desregulación financiera, tomando en cuenta el desarrollo institucional de los países miembros de cualquier tratado de libre comercio. Palabras clave: servicios financieros, comercio internacional, globalización, libre comercio. * Investigadora del Instituto de Investigaciones Jurídicas de la UNAM. * Nota: Debido que la traducción es automática podrá ser inexacta o contener errores.
Apuntes sobre las opciones de cambio en la metodología de la enseñanza del derecho en México

Número 111Septiembre - Diciembre 2004Nueva Serie Año XXXVIIISSN 0041 8633 APUNTES SOBRE LAS OPCIONES DE CAMBIO EN LA METODOLOGÍA DE LA ENSEÑANZA DEL DERECHO EN MÉXICO José María Serna de la Garza * Existen razones importantes que justifican una modificación en la metodología de la enseñanza del derecho en México. El cambio social ocurrido en las últimas décadas y la llamada transición jurídica exigen un ajuste en la forma en que se enseña y se aprende el derecho. La forma tradicional de enseñanza se ha basado en el método de la cátedra magistral, el cual ha inhibido el empleo de nuevas metodologías educativas. En el presente artículo, el autor examina distintas opciones de cambio en la metodología de la enseñanza del derecho en México. En particular, se refiere a métodos de enseñanza activa, mismos que implican, por parte de profesores y alumnos, el examen crítico de sentencias, así como la resolución de problemas. La propuesta, finalmente, consiste en avanzar en el sentido de lograr un conocimiento más profundo de los métodos activos, así como en la identificación de técnicas que permitan aplicarlos y puedan ser combinados con el método tradicional de la cátedra magistral.. Palabras clave: enseñanza del derecho, método de casos, método de problemas, transición jurídica. * Investigador del Instituto de Investigaciones Jurídicas de la UNAM. * Nota: Debido que la traducción es automática podrá ser inexacta o contener errores.
Evolución de las técnicas de cooperación internacional entre autoridades en el derecho internacional privado

Por un lado, se da un proceso de crisis, debido a que la autonomía científica alcanzada por los sectores de la competencia judicial internacional y la eficacia extraterritorial de las decisiones, impiden seguir defendiendo la unidad intrínseca del derecho procesal civil internacional. Por otro lado, se da un proceso de expansión o auge que llega incluso a cuestionar los cimientos básicos de la concepción tripartita o nuclear del derecho internacional privado. De esta forma, la autora realiza en este artículo un análisis de la evolución de las técnicas de cooperación internacional que han influido en el derecho internacional privado y en el panorama del derecho internacional en general.

Victimización y vulnerabilidad por ausencia de legislación y otras medidas en materia de violencia familiar

Número 112Enero - Abril 2005Nueva Serie Año XXXVIIIISSN 0041 8633 VICTIMIZACIÓN Y VULNERABILIDAD POR AUSENCIA DE LEGISLACIÓN Y OTRAS MEDIDAS EN MATERIA DE VIOLENCIA FAMILIAR María de Montserrat PÉREZ CONTRERAS * El fenómeno de la violencia familiar tiene serias repercusiones en los individuos, en las familias, en la sociedad y para el propio Estado. En el presente ensayo, la autora defiende la tesis de que dicho fenómeno debe ser considerado como una prioridad de atención, tanto por organismos gubernamentales como no gubernamentales y sus respectivos proyectos de acción. Por esto, para lograr erradicar la discriminación y la violencia contra la mujer y los menores, y alcanzar el respeto a su dignidad, su derecho al desarrollo y a su participación, es necesario considerar en la estructura, contenidos y fines del sistema educativo, los derechos reconocidos y protegidos por instrumentos internacionales firmados por México en la materia, los compromisos que se asumen a través de ellos, y también los instrumentos constitucionales que los garantizan. Palabras clave: víctimas, grupos vulnerables, violencia familiar, derechos fundamentales. * Investigadora del Instituto de Investigaciones Jurídicas de la UNAM. * Nota: Debido que la traducción es automática podrá ser inexacta o contener errores.
Violencia masiva patrocinada por el Estado. Responsabilidad criminal y "reconciliación"

RESPONSABILIDAD CRIMINAL Y "RECONCILIACIÓN" * Jean-Michel SIMON ** A partir de procesos de transición política experimentados por diversos países, en años recientes se ha suscitado una discusión que gira en torno a la relación entre reconciliación y responsabilidad criminal: lo que en inglés se ha denominado transitional justice. Desde 1989 se han realizado muchos esfuerzos para equilibrar y legitimar los diferentes modos de tratar la violencia patrocinada por el Estado y perpetrada antes de un cambio en el status quo del poder en la sociedad. En el presente ensayo se examinan todas las posibilidades que implica este debate, incluyendo cambios de perspectiva respecto del paradigma de la impunidad que se ha generado en los últimos años. Palabras clave: reconciliación, responsabilidad penal, sistema de justicia, transiciones. * Ponencia presentada en el Senado de la República de México, D.
