التعرية المائية وهشاشة التوازنات البيئية؛ حالة الجزء السفلي لحوض واد زا (المغرب الشرقي)
Authors: بنحامد عبد الرحيم , اسباعي عبدالقادر
Published: July 2024

عرف ممر وجدة – تازة تحولات مجالية أدت إلى إفراز مشاكل تهدد الحفاظ على الموارد الطبيعية واستدامتها. ومن أهم أسباب هذه التحولات مشكل التعرية المائية، الذي يعتبر نتيجة حتمية للتغيرات المناخية وما تفرزه من ظواهر طبيعية متطرفة (الجفاف، انفراج الغطاء النباتي، تركز التساقطات في الزمان والمكان)، مما أدى إلى تدهور الأراضي بالجزء السفلي من حوض واد زا، زاد من حدته الضغط البشري وما يرافقه من تحولات في أنماط الاستثمار التي أدت إلى تفعيل وتسريع العمليات المورفودينامية، مما خلق مجموعة من المشاكل البيئية والاقتصادية والاجتماعية (فقدان التربة، توحل السدود، هجرة السكان ...). تهدف هذه الدراسة إلى معرفة خصوصيات الوسط وتحديد مختلف العوامل المسؤولة عن خطر التعرية المائية، وتقييم مدى هذا الخطر عبر تحليل المعطيات المتوفرة ، والقيام بقياسات مباشرة في الميدان باستغلال المقلد المطري، وتقدير كمية التربة المفقودة من خلال المعادلة العالمية لتكميم التربة المفقودة (USEL). بعد حساب مختلف العوامل، تبين أن 7 % من مساحة الحوض تعرف تعرية قوية، ويقدر متوسط كمية التربة المفقودة ب 5,2 طن/هكتار/سنة، في حين أن القياسات المباشرة بينت الاختلافات الواضحة في الاستجابة الهيدرولوجية وكميات التربة المفقودة وذلك بدلالة اختلاف الخصائص الطبيعية (طبيعة التربة، درجة انحدار السفوح، التوجيه ...) وأنماط الاستثمار (أرض مستريحة، محروثة، اتجاه الحرث ...). حيث تراوحت كمية التربة المنزوعة ما بين 0,12 طن/هكتار بالنسبة للمشارات ذات غطاء نباتي، و3,23 طن/هكتار للأراضي العارية وذات انحدارات قوية.

Avoiding lithium dendrites at the lithium/ceramic electrolyte interface and as a result avoiding cell short-circuit when plating at practical current densities remains a significant challenge for all-solid-state batteries. Typically, values are limited to around 1 mA cm-2, even, for example, for garnets with a relative density of >99%. It is not obvious that simply densifying ceramic electrolytes will deliver high plating currents. Here we show that plating currents of 9 mA cm-2 can be achieved without dendrite formation, by densifying Argyrodite, Li6PS5Cl, to 99%. Changes in the microstructure of Li6PS5Cl on densification from 83 to 99% were determined by FIB-SEM tomography and used to calculate their effect on the critical current density (CCD). Not all changes in microstructure with densification act to increase CCD. While smaller pores and shorter cracks increase CCD, lower pore population and narrower cracks act to decrease CCD. Calculations show that the former changes dominate over the latter, predicating an overall increase in CCD, as observed experimentally.
Application of Deconvolution in Path Integral Simulations
Authors: Madarász Ádám , Laczkó Gergely
Published: July 2024

In path integral molecular dynamics (PIMD) simulations, additional vibrations appear beyond the physical vibrations. In harmonic approximation, the frequencies of these internal modes can be determined from the physical frequencies. We show that this formal effect of the path integral simulations on the vibrations can be considered as a convolution if we use the square of the frequency as an independent variable. This convolution can be represented as a matrix multiplication. The potential of the formalism is demonstrated in two applications. We present an alternative method to determine the power spectrum of thermostats used in PIMD simulations. We also show that in simple anharmonic model systems, the physical frequencies can be obtained from ring polymer molecular dynamics simulations by deconvolution.

Published: July 2024

This research aims to examine the representation of humanism ideology in Anies Baswedan's speech at the Palestine Solidarity Action using a transitivity analysis approach in systemic functional linguistics. The research data consists of the speech text delivered by Anies Baswedan on November 5, 2023. Data collection was conducted using recording and note-taking techniques. The speech text was transcribed to ensure data accuracy. The analysis is conducted by identifying types of transitivity processes and interpreting the meanings and ideologies contained within them. The results of the research indicate that Anies Baswedan's speech is dominated by material processes, which construct the Palestine Solidarity Action as a tangible movement and concrete participation. Mental processes are used to build solidarity and empathy, while relational processes affirm ideological principles such as independence as a fundamental right. Verbal processes represent efforts to voice the movement's aspirations and demand justice, while behavioral and existential processes construct the audience as witnesses and active participants. Transitivity analysis reveals the manifestation of humanism ideology, emphasizing respect for human dignity, opposition to oppression, and a call to uphold justice for the Palestinian people. This research contributes to the understanding of language use in representing ideology within the context of social movements in Indonesia. AbstrakPenelitian ini bertujuan untuk mengkaji representasi ideologi humanisme dalam pidato Anies Baswedan pada Aksi Bela Palestina dengan menggunakan pendekatan analisis transitivitas dalam linguistik sistemik fungsional. Data penelitian berupa teks pidato yang disampaikan oleh Anies Baswedan pada tanggal 5 November 2023. Analisis dilakukan dengan mengidentifikasi jenis-jenis proses transitivitas dan menginterpretasikan makna serta ideologi yang terkandung di dalamnya. Hasil penelitian menunjukkan bahwa pidato Anies Baswedan didominasi oleh proses material yang mengonstruksikan gerakan Aksi Bela Palestina sebagai aksi nyata dan partisipasi konkret. Proses mental digunakan untuk membangun solidaritas dan empati, sementara proses relasional menegaskan prinsip-prinsip ideologis seperti kemerdekaan sebagai hak asasi. Proses verbal merepresentasikan upaya menyuarakan aspirasi gerakan dan menuntut keadilan, sedangkan proses behavioral dan eksistensial mengonstruksikan audiens sebagai saksi dan partisipan nyata. Analisis transitivitas mengungkapkan manifestasi ideologi humanisme yang menekankan penghargaan terhadap martabat manusia, penentangan penindasan, dan seruan untuk menegakkan keadilan bagi rakyat Palestina. Penelitian ini berkontribusi pada pemahaman tentang penggunaan bahasa untuk merepresentasikan ideologi dalam konteks gerakan sosial di Indonesia.
HB-EGF activates EGFR to induce reactive neural stem cells in the mouse hippocampus after seizures

Published: July 2024

Hippocampal seizures mimicking mesial temporal lobe epilepsy cause a profound disruption of the adult neurogenic niche in mice. Seizures provoke neural stem cells to switch to a reactive phenotype (reactive neural stem cells, React-NSCs) characterized by multibranched hypertrophic morphology, massive activation to enter mitosis, symmetric division, and final differentiation into reactive astrocytes. As a result, neurogenesis is chronically impaired. Here, using a mouse model of mesial temporal lobe epilepsy, we show that the epidermal growth factor receptor (EGFR) signaling pathway is key for the induction of React-NSCs and that its inhibition exerts a beneficial effect on the neurogenic niche. We show that during the initial days after the induction of seizures by a single intrahippocampal injection of kainic acid, a strong release of zinc and heparin-binding epidermal growth factor, both activators of the EGFR signaling pathway in neural stem cells, is produced. Administration of the EGFR inhibitor gefitinib, a chemotherapeutic in clinical phase IV, prevents the induction of React-NSCs and preserves neurogenesis.

The life of Bagan speaks through its villages, from the founding set of nineteen some two thousand years ago, until today. This formative role of villages, however, has been side-lined by the fame of Bagan as the centre of a great Buddhist empire. The present article focuses on one village, Myinkaba. The location, its history, tangible and intangible characteristics underpin an evolving community of trade, production and religious patronage. Other villages at Bagan likewise have developed their own personalities making this analysis a proposal and potential template for bringing a new perspective to dynamics of the ancient city and its sustainable future. Like all the villages of Bagan, Myinkaba’s culture is Buddhist yet mixed with animist and other elements from the interaction of Pyu, Bamar and Mon groups over many centuries. Of the capital’s nineteen ‘founding’ villages, Myinkaba is the only one anchored on a large seasonal water body or in-gyi. The prime location on the Ayeyarawady River has enabled trade in bamboo used for lacquer and other products over many centuries. The site also contains evidence of glass production and smelting in a series of kilns. Festivals earn income for the temples, with sale of traditional snacks and a puppet competition. Inscriptions and historical links with the ‘captured’ eleventh century ruler of Thaton, King Manuha, add associations to Mon areas of Lower Myanmar. We construct a working model to encourage further village-based excavation, related research and education in future years that may also contribute to the sustenance of the UNESCO World Heritage site of Bagan.

Legitimando la gordofobia a través de la medicalización: una revisión crítica de la gordura y la gordedad
Authors: Ramírez-Torres Marion
Published: July 2024

En el presente artículo se realiza una revisión crítica conceptual de términos utilizados frecuentemente en las ciencias de la salud y ciencias sociales para referirse a un tipo corporal caracterizado por ser grande, debido a la presencia de mayor adiposidad, considerando que en el contexto del mundo global surgen nuevas identidades que demandan reconocimiento y visibilidad más allá de su estado de salud, como pretende mirar la biomedicina. Se propone transitar hacia el término gordedad para referirnos a aquellas prácticas que son encarnadas por personas que se viven cotidianamente como gordas o gordos sin que deba intervenir necesariamente consideraciones sobre el estado de salud o nutricional ni la mirada patologizadora de considerar esta condición exclusivamente como enfermedad y a las personas que la encarnana, enfermas. Se invita a escudriñar estos términos y considerar dejar de utilizarse como genéricos, por el estigma que conlleva y porque las mismas personas identificadas como gordas o gordos han empezado a emerger con pronunciamientos políticos que reivindican la expresión para hablar de su cotidianidad. Se propone un análisis epistemológico de cómo entendemos la gordura y la obesidad para abonar y permitir el desarrollo conceptual de gordura y gordedad.
Transdisciplina y economía
Authors: Pérez Álvarez Alan Omar
Published: July 2024

El presente artículo se propone el establecimiento de un puente cognoscitivo entre la economía y la transdisciplinaria con el objeto de construir una perspectiva transeconómica de la música popular grabada en el capitalismo contemporáneo. La economía neoclásica y la economía marxista han dedicado una importante cantidad de trabajos al estudio de la cultura en el sistema capitalista desde mediados del siglo XX hasta principios del XXI; sin embargo, tanto la primera como la segunda han priorizado la investigación de la lógica y el valor económicos de las mismas en detrimento de otras lógicas y elementos esenciales en la economía de la música en las sociedades contemporáneas. De ahí que se plantee la necesidad y la urgencia de aplicar los axiomas metodológicos básicos y los operadores cognoscitivos complejos de la transdisciplina al proceso por el que se producen, circulan y se consumen los objetos subjetivantes, los sujetos objetivados y las subjetividades objetuales en la música-pop del capitalismo neoliberal.
Understanding Political Integration Among Syrian Refugees in Calgary
Authors: Vitale Mathew , Hamilton Leah
Published: July 2024

Newcomers to Canada are essential for the nation's cultural and economic vitality. However, research has primarily focused on immigrant integration, overlooking refugees. This study aims to fill this gap by examining the political integration of Syrian refugees in Calgary, Alberta, based on 21 semi-structured interviews. Specifically, it seeks to answer two main questions. First, what factors facilitate the attitudinal and behavioural political integration of Syrian refugees in Calgary? Second, what is the role of social capital in facilitating the attitudinal and behavioural political integration of refugees? Utilizing deductive thematic analysis, the study uncovers a need for enhanced political education. It also identifies the impact of individual variables like news consumption and political interest. A sense of belonging to Canadian society also emerged as an influential factor in political integration. Moreover, social capital, exemplified through membership in organizations, increased political participation and a sense of belonging. These findings suggest the need for new theories specifically focused on refugee political integration.

O descaso com os direitos quilombolas e o apagamento histórico da diversidade cultural são frutos da dominação colonial perpassada por séculos no Brasil. Face a essa perspectiva, o artigo investiga as razões que desencadearam a conservação da realidade de exclusão política e social dos quilombos. A questão elucidada é: quais as respostas do Estado brasileiro para o descaso frente ao dever jurídico de perseguir a concretização dos direitos pluriétnicos consagrados na Constituição Federal, em especial, consolidar os direitos ao reconhecimento e titulação dos Territórios ocupados pelos povos quilombolas? A partir da obra “Em Defesa da Sociedade” de Michel Foucault (1976), demonstrou-se que: (1) a manutenção da segregação é produzida por meio de estratégias de verticalização do poder e (2) os antagonismos se fortalecem e trazem consigo possibilidades de reconfigurações sociais. Parte-se da premissa de que o Estado brasileiro é omisso à sua obrigação de agir para a concretização dos direitos dos povos quilombolas, e, consequentemente, é responsável pela violação desses direitos. O método dedutivo é instrumentalizado no trabalho presente pela pesquisa bibliográfica e documental. Por fim, constatou-se que a negligência do Estado propicia a perpetuação de antigos domínios- pautados em desrespeito à pluralidade-, e, portanto, a ruptura desse contexto fica a cargo de mobilizações dos subjugados por meio de mecanismos concretos de tomada de consciência e ocupação dos espaços de poder.
BIOPOLÍTICA, DECOLONIZACIÓN Y ESCUELA: ¿CUÁL ES EL LUGAR DE LA ENSEÑANZA?
Authors: Fortunato Ivan , Rodriguez Milagros Elena
Published: July 2024

En este artículo se discute el lugar de la enseñanza en la biopolítica decolonial. El objetivo es enumerar algunas posibilidades didácticas para afrontar el mundo neoliberal, coordinado por políticas silenciosas basadas en el racismo, la xenofobia, la homofobia, la aporofobia, entre otras, cuyo lema principal puede describirse como sálvese quien pueda. Para construir una Didáctica relevante para el movimiento decolonial es necesario, en primer lugar, entender la escuela como una institución burocrática al servicio del status quo, cuyo control se realiza a través de pruebas y currículos oficiales. Además, es necesario entender que el modelo de sociedad que tenemos es injusto y desigual, sostenido a través del discurso de que todas las personas pueden ascender socialmente por su propio esfuerzo. Lo que todo esto esconde es que por cada individuo que triunfa en la vida, muchos otros quedan atrás, al margen de su propia condición, por mucho que lo intente.
MERCOSUR and the European Union: Variation and Limits of Regional Integration
Authors: França Rafael Francisco
Published: July 2024

O livro faz uma comparação entre o MERCOSUL e a União Europeia para explicar a variação do regionalismo e expor seus limites. O projeto é baseado na ideia de que exemplos contemporâneos de regionalismo devem ser avaliados contra várias proposições de teorias de integração múltipla, em vez de contra uma única teoria. A fim de explicar sistematicamente por que e como os resultados da integração no MERCOSUL diferem dos da UE, o autor desenvolve um quadro analítico para a comparação dos dois blocos. O MERCOSUL é comparado com a UE pelo uso dos vários critérios de interdependência econômica, convergência econômica, tamanho intra-bloco e assimetrias de interesse, diversidade cultural e motivações geoestratégicas, que são identificados como os parâmetros salientes das teorias de integração.
SEMENTES QUE SUSTENTAM A VIDA: EXPERIÊNCIAS DE CONSTRUÇÕES BIOPOLÍTICAS INSURGENTES NA DEFESA DOS TERRITÓRIOS E DOS COMUNS
Authors: Nóbrega Luciana Nogueira , Barbosa Lia Pinheiro
Published: July 2024

A expansão de um modelo de desenvolvimento agrícola de grande escala e uma política econômica baseada nas commodities, notadamente neoextrativista, evidenciam o interesse de expansão do capital transnacional, sobretudo no território latino-americano. Frente a esse contexto, a defesa dos territórios e dos comuns revela seu caráter intrínseco à histórica resistência dos povos originários, camponeses, quilombolas e populações tradicionais na região que, incidido no enfrentamento desse novo padrão de acumulação, propõem projetos políticos baseados em outra biopolítica. Assim, na defesa dos territórios e dos modos de vida, esses diferentes povos constituem um patrimônio biocultural, assentado em uma memória coletiva, que tem fomentado a preservação e a circulação de sementes crioulas, sementes da vida ou sementes da cultura. Ao preservarem suas sementes e, com elas o conhecimento e as relações sociais que as forjam, os povos originários, do campo, das florestas e das águas contrapõem-se à lógica ampliada do capital, que as trata como bens comercializáveis, estéreis e dependentes de insumos e de agrotóxicos. No presente artigo, apresentamos experiências de construções biopolíticas insurgentes baseadas em uma apreensão onto-epistêmica das sementes como sustentáculo da vida e sua centralidade na defesa dos territórios e dos comuns.

Introduction: Despite the benefits of Cardiac Rehabilitation (CR), local and national CR referral and participation rates remain low when compared to established cardiovascular therapies, especially amongst racial/ethnic groups. Objectives: This study investigated the effects of the implementation of a CR program and electronic order set (EOS) in a large health system on CR referral and participation rates among a diverse group of patients with Coronary Heart Disease (CHD). Methods: A total of 360 patients from UCSD Health who presented with ACS were prospectively evaluated during initial hospitalization and 6- and 12-weeks post-discharge. The multivariable logistic regression model assessed referral and participation rates by week 1 and -12 post-discharge, adjusting for gender, age, race, ethnicity, geography, and referring physician subspecialty. Results: UCSD CR program implementation led referral rates to increase at week 1 (Pre- 38.6% and Post-54.9%, p = 0.003) and week-12 (Pre- 54.1% and Post- 59.8%, p = 0.386). Post-CR referrals were more likely at week-1 (OR: 1.93, 95% CI 1.27-2.95) and week-12 (OR: 1.26, 95% CI 0.79-2.00). EOS implementation increased referral rates at week-1 (Pre- 40.3% and Post- 58.7%, p < 0.001) and week-12 (Pre- 54.9% and Post- 60.4%, p = 0.394) with referrals more likely at week-1 (OR: 2.1, 95% CI 1.35-3.29) and week-12 (OR: 1.25, 95% CI 0.795-1.98). Participation in CR following EOS was more likely at both week-1 and week-12. Multivariable analysis revealed disparities in referral based on race, geographic location, and referring physician subspecialty. Conclusion: A CR program and EOS implementation were shown to increase referral rates with long-term potential for increasing referral and participation rates. Condensed abstract: This prospective study investigated the implementation of a Cardiac Rehabilitation (CR) program and Electronic Order Set (EOS) within the same health system on CR referral and participation rates. 360 patients with ACS were evaluated over 12 weeks. UCSD CR program and EOS implementation led referral rates to increase at week-1 and -12. CR participation was more likely to increase at week-1 and -12 following EOS. Multivariable analysis revealed disparities in referrals disproportionally affecting racial and ethnic minority groups and rural communities. CR and EOS implementation may increase CR referral rates for diverse patients with CHD.

Authors: Roger Lee  , Jorge Usaquen  , Fredy Martínez
Published: July 2024

This paper explores the development of low-cost stereoscopic vision systems for robotics, with a focus on educational applications. Stereoscopic vision, essential for depth perception, allows robots to navigate and interact with their environment more effectively. However, the high cost and complexity of existing solutions limit their accessibility and integration into educational robotics. This review addresses these challenges by examining affordable technologies, such as FPV cameras and ESP32 microcontrollers, which are redefining the possibilities for cost-effective robotic systems. Through a systematic literature review, this study synthesizes findings from various academic databases, highlighting the technical advancements and educational applications of stereoscopic vision in small and mobile robots. It also presents case studies demonstrating the successful implementation of these low-cost systems in real-world scenarios, providing insights into their performance and the lessons learned. The findings suggest that integrating low-cost technologies not only makes robotic education more accessible but also enhances learning outcomes by providing students with hands-on experience in advanced robotic systems. This paper contributes to the ongoing discourse in robotic education by proposing scalable, cost-effective solutions that could be pivotal in democratizing advanced robotic technologies in educational settings.
