Authors: Mustafa Muamar Rafizan , Abdul Hamid Mohammad Fahmi , Zur Raffar Izzah Nur Aida , Meerangani Khairul Azhar
Published: February 2025

Since its inception in 1985, the Takmir education program has significantly contributed to enhancing knowledge and fostering the Muslim community’s development in Malaysia. However, managing this program often faces challenges in terms of monitoring, coordination, and system efficiency. This study aims to analyze the impact of integrated management through the introduction of the MyTakmir system on the development of Takmir education management in Negeri Sembilan. The study employs a qualitative methodology involving document analysis, systematic data review, and interviews with Takmir Officers from the Negeri Sembilan Department of Islamic Religious Affairs (JHEAINS). The findings reveal that the implementation of the MyTakmir system has not only addressed traditional weaknesses in Takmir management, such as manual documentation and delayed claim processes, but also improved the transparency and efficiency of monitoring Takmir instructors. Key advantages of this system include centralized data management, streamlined teacher placements, and the ability to monitor attendance statistics and subject frequency in real time. Additionally, the system enables strategic analysis for controlling the dissemination of knowledge, thereby supporting efforts to combat deviant teachings. The study suggests that other states should adopt the MyTakmir system as a model for integrated management, enhancing it by integrating it with other religious departments and emphasizing the effectiveness of Takmir education pedagogy. It is hoped that this innovation will serve as a catalyst for creating a more dynamic and systematic Islamic education ecosystem to address contemporary challenges and elevate mosques and suraus as core knowledge centers within the Muslim community.

Halal Certification by Globalization: Packaging Variance, Enhancing Efficiency and Lowering Compliance Barriers
Authors: Othman Hasbullah , Ibrahim Irwan
Published: February 2025

In various sectors such as food, drink, cosmetics, pharmaceuticals, and logistics, halal certification is crucial for ensuring compliance with Islamic law (Shariah). While the international demand for halal-certified products is increasing, motivated by the fact that an ever-growing proportion of consumers, among both Muslims and non-Muslims, are actively searching for ethical and religion-compliant products, the halal certification process has come under immense strain because of its complex and heterogeneous nature across several markets and certification authorities. Halal certification processes need to be standardized and harmonized significantly so that barriers to market access can be eliminated, product credibility can be guaranteed and certification procedures can be simplified. While halal certification gains importance among consumers and businesses, research analysing the efficiency of the certification process, the barriers businesses face, and possible global harmonization of regulations lacks. The proposed study utilizes qualitative research, conducting interviews with halal certifying authorities, businesses and industry experts, and analysis of certification processes in different countries to explore these issues. However, cultural and religion differences are problematic for harmonization. The research also highlights inefficiencies in the certification process, such as prohibitive costs and long wait times — especially in non-Muslim-majority countries. The study concludes with recommendations on how to facilitate a global halal certification platform, through digitalisation, and capacity building for small and medium-sized enterprises (SMEs) to help mitigate barriers to halal certification and market access.

Environmental Impact Assessment in Developing Urban Economy: A Perspective of Challenges Impeding Public Participation in Traditional City of Bida, Nigeria
Authors: Chado Jiman , Doko Garba , Salihu Haruna
Published: February 2025

Evidences reveal that broad-based social capital and social inclusion has been
failing in the practices of public participation in Environmental Impact
Assessment for the development of urban economy in less-developed countries.
The impact of broad-based failing on urban economy is intensified by series of factors
namely; organic community development, lack of successful development control and
behavioural attitude of populace among others. For a traditional city which needs a high
number of infrastructural developments as part of socio-economic and environmental
management, public participation as a module of decision-making process, is more
complex, due to micro-based factors as challenges in traditional cities of Africa. To date,
studies on public participation center expansively on macro-based factors with little or
no concentration to examine micro-based factors on government-based projects. This
study therefore, tends to identify challenges causing broad-based deterioration by
focusing on examining the micro factors impeding public participation in government-
based projects. In this study, quantitative research method using questionnaire survey
was adopted with 344 questionnaires were administered to examine micro-factors
hindering citizens to participate in Environmental Impact Assessment. The sampled
frame includes; planning officers, traditional leaders, youth leaders and household
heads. Standard multiple regression analysis was adopted to recognize factors affecting
citizens to participate in urban planning and management. This study suggests areas of
encouraging broad-based participation and apparently could be used by the
environmental planning practitioners and law makers in the traditional cities of
developing countries, like Bida in Niger State, Nigeria.
Review of Minimalistic Architecture
Authors: Ogbonnaya I. O. , Alozie G. C. , Aneke C. G.
Published: February 2025

The escalating global population density, coupled with finite land
availability, has necessitated the development of efficient and
sustainable architectural solutions, particularly within urban contexts.
Minimalist Architecture presents a compelling paradigm to address these
challenges through its core tenets of simplicity, functionality, and judicious
utilization of space. This empirical investigation aims to conduct a
comprehensive analysis of Minimalist Architecture's principles and
applications in the design of residential and commercial structures. By
employing a multifaceted approach encompassing historical influences,
theoretical frameworks, and contemporary case studies, the research strives to
demonstrate the potential of Minimalist Architecture to navigate the
complexities arising from land scarcity and population growth. Fundamental to
this architectural style is the integration of basic geometric forms, reduction of
extraneous elements, and prioritization of efficient spatial planning, thereby
facilitating the creation of structures that optimize functionality within confined
footprints. Furthermore, the study explores the synergistic incorporation of
cutting-edge technologies and sustainable practices into Minimalist
Architecture, underscoring its adaptability and flexibility to accommodate
evolving needs and environmental conditions. Through a critical examination
of existing critiques and practical limitations, the research seeks to provide
insights into potential solutions to overcome these challenges, ultimately
positioning Minimalist Architecture as a viable and forward-thinking approach
to address the pressing global issues of land scarcity and population growth

The Use of Video Call Sex in Fulfilling Sexual Desires: Jacques Lacan's Perspective
Authors: Freny Matahari Frisky , Jamilah Mihardjha Eli
Published: February 2025

The emergence of digital technology, particularly online communication, has opened up new avenues for fulfilling sexual desires. Video call sex is one such phenomenon, offering an alternative for long-distance sexual interaction. Jacques Lacan's psychoanalytic concepts of the real, imaginary, and symbolic provide a unique lens for analyzing this phenomenon. This research aims to analyze the phenomenon of using video call sex to fulfill sexual desires according to Lacan's psychoanalytic perspective. This qualitative study employed in-depth interviews with three female participants who actively engaged in video call sex. The findings reveal that modern communication media have transformed traditional concepts of sexuality, enabling virtual activities like video call sex to fulfill sexual needs. Desire, as Lacan posits, is the primary motivator for engaging in video call sex. Sexual satisfaction in this context is not solely reliant on the physical presence of a partner but also on their mental image, or imagination. This unfulfilled desire continually demands satisfaction, leading individuals to repeatedly engage in such activities. Lacan's perspective suggests that video call sex has shifted from a need to a desire. This desire, residing in the realm of symbols and the unconscious, necessitates continuous fulfillment. This research contributes to the understanding of how technology shapes modern sexuality and how psychoanalytic concepts can offer insights into the motivations and dynamics of virtual sexual practices.
Digital Communication In Customer Satisfaction: A Case Study On The Use Of Satisfaction Surveys
Authors: Handayanti Asih , Darmawan Ferry
Published: February 2025

The use of digital surveys is becoming increasingly important in collecting customer satisfaction data, especially in the competitive garment accessories industry. However, the limited representation of respondents in digital surveys remains a challenge. This study aims to explore the factors that influence customer satisfaction, focusing on product quality, service speed, and feedback systems. A qualitative approach with a case study method is applied to understand customer experiences in depth. Data were collected through an online survey focusing on key aspects of customer satisfaction and analyzed descriptively. The findings show that product quality is a key factor in customer satisfaction, while service speed and a responsive feedback system become more important for new customers. Although digital surveys are effective in capturing customer perceptions, bias can occur due to the limited representation of customers less familiar with digital technology. These results align with findings in other industries, which show the importance of service quality and responsive interactions in building customer satisfaction. However, a multi-channel approach is recommended to improve respondent representation in digital surveys. This research provides insights into the factors that affect customer satisfaction in a digital context and recommends a multi-channel survey strategy to improve the validity and representativeness of the results.

Tuberculosis (TB) is one of infectious disease that still remains a public health concern. Various factors affecting the TB treatment success rate including public knowledge, attitude, and stigma. Public knowledge and attitude directly associated with individual awareness that impacts TB transmission and early screenings for TB. This study aimed to assess public knowledge, attitude and stigma regarding TB in Surabaya, Indonesia and specifically analyzed the associated factors of having poor TB attitude. An observational, cross-sectional study was conducted using self-administered online questionnaire. Individuals age 18 years old or above were recruited at six different pharmacies in Surabaya during their visit and those who decided to withdraw after fulfilling the questionnaire were excluded. A total of 436 participants were recruited for this study. Of them, females were predominant (71.3%) and the majority of them were in the age groups of 18 to 30 years (69.3%). They were mostly had graduated from secondary school (60.3%). Concerning income, most of participants earned less than 1 million IDR. Regarding their levels of knowledge, attitude and stigma, the majority of them had good knowledge (50.7%), moderate attitude (47.5%), and positive stigma (93.1%). The significant associated factor of having poor attitude was knowledge which participants with good knowledge were less likely to have poor attitude (b= -1.103; OR = 0.332; p-value 0.000). Therefore, increasing level of public knowledge related to TB will significantly increase their attitude towards TB.

The study focused on the purpose of finding out the effect and covering fraud in the National Health Insurance. Fraud is an act carried out intentionally to gain financial gain from the JKN program in the National Social Security System, through fraudulent acts that are not in accordance with the provisions of laws and regulations. Health fraud is a serious threat to the world, causing financial misuse of scarce resources and negative impacts on access to health, infrastructure, and social determinants of health. In Indonesia, cases of fraud continue to increase from year to year. The purpose of this study is to find out the latest studies related to the analysis of the opportunities for fraud in health insurance, and how the mechanism for effective prevention and mitigation efforts can be implemented in the implementation of the Health Insurance program in Indonesia. The method used in this journal uses qualitative descriptive through a literature study approach. Opportunities for fraud practices in JKN can be identity falsification, collusion to make false claims, unnecessary health care, excessive invoices, deviations or upcoding of diagnosis codes, document discrepancies, and duplicate claims. The reasons for fraud that usually occur are known as the fraud triangle, namely motivation, opportunity, and rationalization. Result of this study suggested systematic prevention efforts are needed together by health service providers, BPJS, and the Government by implementing the principles of a fraud prevention system, and the formation of a fraud prevention team that is adjusted to the needs for scale of the organization and national, in the future to reduce the negative impacts that occur.

Abstract. Air ions play a crucial role in the new particle formation (NPF), which in turn has the potential to influence global intermediate ions and 7–20 nm large ions) at two “flagship” sites: the SMEAR II site in boreal forest of Finland and the SORPES site in megacity of eastern China. Air ion number size distributions (0.8–42 nm) were measured using a Neutral Cluster and Air Ion Spectrometer (NAIS) at these two sites from June 2019 to August 2020. Our study aims to characterize the similarities and differences in ion characteristics and their contributions to NPF between clean forest and polluted urban environments. At both sites, rising temperatures reduced the difference between positive and negative cluster ion climate and air quality. We conducted a comparative analysis of air ions in three size ranges (0.8–2 nm cluster ions, 2–7 nm concentrations, likely due to an increase in ion mean size or enhanced convection and turbulent mixing that diminish the electrode effect. The median cluster ion concentration at SMEAR II (1270 cm−3) was approximately six times higher than at SORPES (220 cm−3), which was caused by the high coagulation sink in the urban area. The median large ion concentration at SORPES was nearly three times higher (197 cm−3) than that at SMEAR II (67 cm−3), which is due to higher aerosol concentrations in megacity, since the cluster ions attaching to neutral particles. The cluster ion concentration was negatively associated with the condensation sink (CS) at both sites, with a significantly stronger negative correlation at SORPES, suggesting that CS was a decisive factor in this urban area. The median formation rates of 2 nm and 3 nm ions at SMEAR II (𝐽2−: 0.033 cm−3 s-1, 𝐽2+: 0.041 cm−3 s-1; 𝐽3−: 0.012 cm−3 s-1, 𝐽3+: 0.016 cm−3 s-1) were similar to those at SORPES (𝐽2−: 0.028 cm−3 s-1, 𝐽2+: 0.025 cm−3 s-1; 𝐽3−: 0.028 cm−3 s-1, 𝐽3+: 0.027 cm−3 s-1). The median ion-induced fractions were 19.9 % and 1.3 % at SMEAR II and SORPES, respectively, indicating a minor contribution of ions to NPF in polluted environments. Nevertheless, the charged particles were activated earlier than neutral particles at SORPES, indicating that the ion-induced nucleation could precede neutral nucleation in this polluted environment. In addition, the contribution of ion-induced nucleation at SORPES was higher at low NPF intensity, implying the non-negligible roles of air ions in aerosol production in urban area.

Abstract. Nitrate plays an important role in the Earth’s climate and air quality. A key challenge in simulating the lifecycle of nitrate aerosol in global climate models is to accurately represent mass size distribution of nitrate aerosol. In this study, we evaluate the performance of the Energy Exascale Earth System Model version 2 (E3SMv2) and the Community Earth System Model version 2 (CESM2), along with Aerosol Comparisons between Observations and Models (AeroCom) phase III models, in simulating spatial distribution of fine-mode nitrate, mass size distribution of fine- and coarse-mode nitrate, and the gas-aerosol partitioning between nitric acid gas and nitrate, using long-term ground-based observations and measurements from multiple aircraft campaigns. We find that most models underestimate the annual mean PM2.5 (particulate matter with diameter less than 2.5 μm) nitrate surface concentration averaged over all sites. The observed nitrate PM2.5/PM10 and PM1/PM4 ratios are influenced by the relative contribution of fine sulfate/organic particles and coarse dust/sea salt particles. Overall, the ground-based observations give an annual mean surface nitrate PM2.5/PM10 ratio of 0.7. Most models underestimate the annual mean PM2.5/PM10 ratio in all regions. There are large spreads in the modeled nitrate PM1/PM4 ratios, which span the full range from 0 to 1. Most models underestimate the surface molar ratio of nitrate to total inorganic nitrate averaged across all sites. Our study indicates the importance of gas-aerosol partition parameterization and simulation of dust and sea salt in correctly simulating mass size distribution of nitrate.
How does the time shift between precipitation and evaporation affect annual streamflow variability? A large sample elasticity study
Authors: Andréassian Vazken , Mendoza Guimarães Guilherme , de Lavenne Alban , Lerat Julien
Published: February 2025

Abstract. One of the most basic questions asked to hydrologists is that of the quantification of catchment response to climatic variations, i.e. that of the variations around the average annual flow given the climatic anomaly of a given year. This paper presents a large sample analysis based on 4122 catchments from four continents, where we investigate how annual streamflow variability depends on climate variables – rainfall and potential evaporation – and on the season when precipitation occurs, i.e. on the synchronicity between precipitation and potential evaporation. We use catchment data to verify the existence of this link, and show that, in all countries and under the main climates represented, synchronicity anomalies come as the second most important factor to explain annual streamflow anomalies: after precipitation but before potential evaporation. Introducing the synchronicity between precipitation and potential evaporation as an independent variable improves the prediction of annual streamflow variability significantly.
Dislocation creep and glide in experimentally deformed glaucophane aggregates
Authors: Hufford Lonnie Justin , Tokle Leif , Behr Whitney Maria , Morales Luiz Grafula , Madonna Claudio
Published: February 2025

Abstract. Glaucophane is a key rheology-controlling mineral in the oceanic crust of subducting slabs at blueschist facies conditions. Studies of naturally deformed glaucophane suggest dislocation-related deformation mechanisms can be activated at some pressure-temperature-stress conditions in subduction environments; however, the strength of glaucophane deforming via these mechanisms remains unconstrained. To address this, we conducted load stepping experiments using a Griggs apparatus at temperatures of 600–700 °C, 1.0 GPa, and shear strain rates of ∼ 1.2×10−⁸ s-1 to ∼ 1.2×10−³ s-1, with a starting grain size of <63 µm. The mechanical data from these experiments show a transition in the stress exponent from 2.8 ± 0.2 at relatively low stresses, indicative of dislocation creep, to 14–19 at relatively high stresses, consistent with dislocation glide. Microstructural analyses show kinking, undulose extinction, and a shift from sharp linear grain boundaries in the hydrostatic samples to more rounded and lobate sutured grain boundaries in the deformed samples. High internal misorientations (subgrains, undulose extinction) in both relict and fine-grained regions of the deformed samples further support the activation of dislocation-related mechanisms. Based on these observations, we develop flow laws for dislocation creep n = 3, Q = 450 ± 15 kJ/mol, A =2.32x10¹⁰ MPa−n s-1) and dislocation glide (Q = 899 ± 43 kJ/mol, C = 1.83x10³², and α = 0.0123). Extrapolations of our flow laws to geologic conditions suggests that dislocation glide is unlikely to occur at steady state conditions, while dislocation creep dominates at temperatures above 450 °C at relatively large grain sizes of ∼1 mm or larger. These insights refine our understanding of glaucophane rheology and its implications for subduction zone mechanics.

En este artículo propongo explorar la cuestión ontológica en el pensamiento de Marx, poniendo el foco en los tratamientos que le dedicaron dos autores habitualmente colocados al margen de los intereses propios del marxismo: Martin Heidegger y Jacques Derrida. Desde perspectivas críticas o deconstructivas, sus interpretaciones se caracterizaron por situar a Marx dentro de la tradición metafísica a partir de la comprensión de su filosofía como una ontología del trabajo o, al decir de Werner Hamacher, como una ergontología. El artículo, entonces, se dedica a analizar los argumentos filosóficos empleados primero por Heidegger y luego por Derrida para cuestionar, de forma diferenciada, aunque en estrecha relación de continuidad, el privilegio metafísico del trabajo en el discurso marxista, sin descuidar las implicaciones políticas de sus respectivos cuestionamientos.
Leibniz y la aplicación de la matemática a la física
Authors: Raffo Quintana Federico
Published: February 2025

En este trabajo analizaremos la concepción de Leibniz acerca de la aplicación de la matemática a la física entre los años 1677 y 1690. Reconstruiremos esta concepción fundamentalmente a partir de algunos conceptos relacionados, como son los de “atributos” o “cualidades acompañantes”. Veremos que, por aplicación de la matemática a la física, Leibniz entendió específicamente la posibilidad de dar explicaciones mecánicas que dan cuenta de la causa inmediata e inteligible por la cual tienen lugar las cualidades confusas, en un sentido que debe ser dilucidado. Estas explicaciones revelan, por lo tanto, la estructura a parte rei a partir de la que tienen lugar las sensaciones.
Qué puede Dios y qué el monarca: dos vías de reconstrucción teológico-política de la filosofía política de Descartes
Authors: Quintela González Héctor
Published: February 2025

A diferencia del grueso de los escritores de su tiempo, René Descartes no se ocupó de la política más que de manera marginal. En este artículo se ensayan dos vías de reconstrucción teológico-política de la filosofía política cartesiana a partir de lo expuesto por Carl Schmitt en sus trabajos sobre teología política. De ellos se pueden derivar dos modos distintos de pensar la teología política. Procediendo a partir del primero de estos modos, expuesto en 1922, Descartes acaba situado entre los defensores del absolutismo, apareciendo su eventual pensamiento político muy próximo al desplegado por Thomas Hobbes; en cambio, las matizaciones de las tesis de 1922 sobre teología política que el jurista lleva a cabo pasadas casi cinco décadas invitan a pensar una política cartesiana que restringe el poder absoluto del rey.
Los políticos y su auditorio (II). La interacción asociada con determinados tipos de información: compartida, noticiosa y reproducida
Authors: Cortés Rodríguez Luis
Published: February 2025

Como parte de nuestro estudio de la conexión del político con el auditorio, nos vamos a ocupar de tres diferentes tipos de información empleados por el orador: I. Información compartida, que encontramos en intervenciones en las que este pretende hacer participar al auditorio de un saber común, si bien, en ocasiones, solo es el pretexto para reforzar la propia opinión y atacar al rival (“saber”, “conocer”, “recordar”, etc.); II. Información noticiosa, que se formula mediante manifestaciones en las que el político anhela dar a conocer, en muchos casos adelantar, determinada información (“anunciar”, “decir”, “explicar”, etc.), y III. Información reproducida, hallada en expresiones en las que el orador se vale de una cita ajena o propia, emitida con mayor o menor fidelidad y que suele servir de soporte para una parte o el resto del enunciado (“decir”, “preguntar”, “según+tiempo verbal”, etc.). Para el análisis, vamos a partir de un corpus que consta de catorce intervenciones de presidentes del Gobierno español y de líderes de la oposición llevadas a cabo en los debates sobre el estado de la nación; tal corpus tiene una duración de 13h58m40s.
Sobre verbos de memoria. Aproximación diacrónica
Authors: Elvira Javier
Published: February 2025

Esta investigación analiza la configuración argumental y las variaciones en el uso de los verbos de memoria del español acordarse, olvidar(se) y recordar, haciendo énfasis en la perspectiva diacrónica. Los datos históricos muestran un diferente comportamiento de estos verbos en relación con las estructuras transitivas. Los hechos medievales muestran una sintaxis argumental muy variada, con todo tipo de interferencias y cruces entre los principales verbos de este dominio semántico. El verbo olvidar, debido quizá a la falta de control en su significado básico, se ha visto atraído desde antiguo a configuraciones de evento no controlado que no ha conocido su opuesto recordar.
Teaching and learning chinese as a heritage language (CHL)
Authors: Zhang Huichao , Gong Yang , Zhang Luyao , Gao Xuesong
Published: February 2025

Research on Chinese heritage language (CHL) education has flourished in recent decades, driven by the increasing presence of CHL learners in schools worldwide, especially in multiethnic and multilingual contexts such as the USA, Canada, and Australia. This article presents the findings of a systematic review of 53 empirical studies on CHL education indexed in the Social Science Citation Index (SSCI) and published from 2008 to 2023. The study reveals that CHL research primarily focuses on four core areas: CHL maintenance, CHL acquisition, CHL pedagogy, and CHL learners’ identity. The research methodologies within the existing literature show a predominance of quantitative studies, particularly laboratory-based research on CHL acquisition, and the results highlight the critical role of the home environment in supporting CHL maintenance. This review concludes with recommendations for advancing future research on and pedagogy practices of CHL. Specifically, CHL education needs to incorporate sociolinguistically-informed pedagogical approaches and materials and implement valid assessment tools to address the diverse needs and interests of CHL learners. Future research should further investigate how CHL learners’ ethnic identities are shaped by and interact with gender, socio-economic status, and dialect backgrounds, while assessing tailored interventions and engaging in classroom-based action research to enhance pedagogy and longterm language transmission across generations
Los marcadores del discurso en la norma culta de la ciudad de Santander (España)
Authors: Peña Arce Jaime
Published: February 2025

El estudio de la variación geográfica y sociolingüística de los marcadores del discurso comenzó hace unos 10 años (Valencia Espinoza 2014a; Valencia Espinoza y Viguera Ávila 2015). Sin embargo, hasta el momento, no se ha publicado ningún trabajo que analice la situación de dichos elementos en una variedad del español centro-septentrional. En las líneas que siguen se ofrecen los resultados obtenidos en la ciudad de Santander, situada en la costa norte de España. Las conclusiones apuntan a la homogeneidad en el empleo de los marcadores del discurso en español con independencia del componente geográfico.

Authors: Bordin Vanessa Benites , Siqueira Correa Gisele
Published: February 2025

Analisaremos o impacto de adaptações para o teatro de contos infantis no processo de ensino-aprendizagem. A escolha deste tema partiu da importância inegável da literatura e do teatro para a formação integral do aluno, considerando a possibilidade de interdisciplinaridade entre essas duas áreas de conhecimento. Dentro desta temática evidenciaremos a atemporalidade dos temas dos contos infantis e sua relevância no contexto educacional. Aportes teóricos reverberam que a literatura infantil, em especial os contos, têm raízes profundas na cultura e na sociedade, influenciando gerações ao longo do tempo. Assim, a prática de contar histórias e a leitura de contos infantis estão associados ao desenvolvimento cognitivo e emocional das crianças, bem como à transmissão de valores e ensinamentos sociais.  Neste contexto, através de uma revisão bibliográfica, este estudo explora a origem e as concepções dos contos infantis, sua relação com o teatro e a formação do aluno. Em seguida, serão discutidas as adaptações teatrais, a representação dos temas nos contos infantis adaptados no contexto contemporâneo, e o impacto dessas adaptações na educação. Deste modo, compreendendo como as adaptações teatrais de contos infantis podem contribuir para a formação cultural e social das crianças, bem como para o ambiente educacional.

Resumo
O presente artigo é um relato de experiência crítico e reflexivo acerca do espetáculo: Crianças... ou Nossas Infâncias Inventadas! (2012). O objetivo é apresentar e analisar um dos principais trabalhos do Coletivo Integrado de Artes Terreiro da Infância, abordando o método, a metodologia e os elementos poéticos constitutivos no processo de montagem, tais como: a memória, a imagem, a imaginação, o imaginário. A partir das notações da direção e dos diários de bordo de dois dos atores e duas das atrizes, pudemos retomar as discussões aqui apresentadas. Acreditamos que expor o trabalho à apreciação escrita, é uma forma de colaborarmos com: novas formas de criação de dramaturgias para a infância; outras maneiras de conceber narrativas infanto-juvenis para crianças; e pautar a relevância dos aprendizados com a infância e com as crianças nos processos de ensino nas licenciaturas em artes da cena, especialmente.
