Authors: Rahmah Nurul , Candradewini Candradewini
Published: November 2023

Berbagai upaya dilakukan pemerintah untuk meningkatkan mutu pendidikan di Indonesia. Salah satnya ialah dengan mengeluarkan kurikulum yang sesuai dengan perkembangan zaman. Saat ini Indonesia akan menggunakan Kurikulum Merdeka sebagai kurikulum nasional, namun saat ini penggunaan kurikulum dilaksanakan secara bertahap. Salah satu sekolah yang menggunakan Kurikulum Merdeka ialah SMA N 1 Kecamatan Guguak. Sehingga guru-guru yang akan menggunakan kurikulum ini harus mengikuti pelatihan tentang Kurikulum Merdeka. Penelitian ini bertujuan untuk mendeskripsikan bagaimana pelatihan Kurikulum Merdeka dilaksanakan. Metode yang digunakan ialah metode kualitatif deskripsi dengan menggunakan pedoman wawancara sebagai instrumen pendukung pelatihan. Hasil penelitian ini menujukkan bahwa pelaksanaan pelatihan tentang Kurikulum Merdeka belum berjalan dengan baik seperti tidak dilibatkannya sasaran pelatihan dalam analisis kebutuhan pelatihan serta perencanaan pelatihan. Sehingga pelatihan yang diberikan masih belum sesuai dengan harapan peserta pelatihan. Selain itu pelatihan juga tidak memiliki evaluasi. Sehingga tidak diketahui ketercapaian tujuan pelatihan ini dilakukan. Sehingga dapat disimpulkan bahwa pelatihan tentang Kurikulum Merdeka di SMA N 1 Kecamatan Guguak masih belum baik. Various efforts have been made by the government to improve the quality of education in Indonesia. One of them is to issue a curriculum that is in accordance with the times. Currently Indonesia will use the Merdeka Curriculum as the national curriculum, but currently the use of the curriculum is implemented gradually. One of the schools that uses the Merdeka Curriculum is SMA N 1 Guguak District. So that teachers who will use this curriculum must attend training of the Independent Curriculum. This study aims to describe how the Independent Curriculum training is carried out. The method used is a qualitative method of description using interview guidelines as a training support instrument. The results of this study show that the implementation of training on the Independent Curriculum has not run well such as the non-involvement of training targets in training needs analysis and training planning. So that the training provided is still not in accordance with the expectations of the trainees. In addition, training also has no evaluation. So it is not known the achievement of the purpose of this training. So it can be concluded that the training of the Independent Curriculum at SMA N 1 Guguak District is still not good.

In general, fungal skin disease is not a deadly disease. Most people who have been infected often leave it alone and think that the disease will heal on its own. However, if left untreated or without prompt treatment, the impact can worsen the patient's condition, one of which is permanent baldness if the fungal skin disease infects the scalp. The importance of early detection and treatment of fungal skin diseases is essential. While the current process requires a person to go to a hospital or a skin and genital specialist doctor, so they have to spend time and money to do early detection and treatment, the availability of expert doctors or experts who know a particular field is quite limited. At the same time, many patients must be diagnosed with the disease immediately and treated immediately. In a clinic, medical officers often experience difficulties when receiving patients who complain of skin diseases caused by fungi.

Therefore, an application was created that can be used to carry out online final semester exam simulations. So that it can overcome all the problems that exist in the final semester exams at SMA Negeri 1 Tanjung Raja, North Lampung.
La danza y el cuerpo: territorios afrocubanos emergentes del siglo XXI
Authors: Torres Díaz Neri
Published: November 2023

This article seeks to give visibility to the migrant nation, to those who emigrate seeking better living conditions and pay the price of abandoning their people, their culture, and the essential features of their identity. To migrate is to camouflage oneself to change from a life with restrictions, to a life of marginality. Reflecting on the concept of border in the 21st century, in light of the migratory phenomenon of Afro-descendants, makes dance and the body emerge as salvation, as the deepest recovery of identity. In the Afro-Cuban diaspora, body and dance become the new universal territory of migration to cope with the loss, not only of maternal land, but also of the right to their own culture.

One of the most popular and successful actors of the golden age of Mexican cinema (1936-1955) was the comedian Germán Valdés Tin Tan who stood out for showing multiple cultural identities in several of his films. In this sense, the objective of this work is to show how many of the characteristics of a film industry with international resonance such as Mexico are expressed in the film The unknown mariachi or Tin Tan in la Habana (1953) in relation to one of its more solid and representative recipient audiences such as Cuba. In this sense, the producers of said film, Germán Valdés, Óscar Brooks and Felipe Mier exploited these traits to the maximum to please that market and benefit economically, since at that time the two countries and their cinematographies had a close bond of production and co-production of films on the island with the particular environments of the same.
Los seres alados y solares del arte maya en el Norte de Yucatán
Authors: Rubén B. Morante López
Published: November 2023

In our field work in northern Yucatán we studied the iconography of sites such as Chichén Itzá, Ek Balam, and Mayapán. There we saw great artistic quality sculptures of human beings that carry wings, and because of that we think that represented celestial beings related to deities of the Mayan pantheon of Late Classic, Terminal Classic and Early Postclassic periods. In our research we started with reviews of ethnohistorical, geographical and archaeological contexts in other Mayan sites, from central and eastern Mexico, including images from codices and paintings that tell us about the possible meaning of feathers, wings and birds in Mesoamerica. We proceeded analyze winged figures presented in relation to important buildings in northern Yucatán sites. Solar evocation suggested probably was common in this area and, sculptures not only speak about belief systems that could emanate from very early Mayan traditions, but also speak about great artists, that in 9th century AD. clearly manifested it through a refined style, technical mastery and high aesthetic sensitivity.
Ilustrando Nepāl en el siglo XIX. El dibujo de Raj Man Singh Chitrakar
Authors: De la Rubia Gómez-Moran Andrea
Published: November 2023

A lo largo de los siglos XIX y XX, cuando las fronteras del Himalaya se encontraban políticamente cerradas a la intromisión extranjera, los pocos científicos europeos que tuvieron la fortuna de adentrarse en el valle de Nepāl lo hicieron usualmente junto a un grupo de artistas citrakār indios o nepalíes. Desde el anonimato, estos artistas contribuyeron al desarrollo del conocimiento científico de flora, fauna y culturas del Himalaya, gracias a su extraordinaria habilidad en el dibujo realista. El siguiente artículo se centra en la figura del británico, naturalista y etnólogo Brian Houghton Hodgson, y en sus estudios sobre la biología himaláyica y la cultura budista newār. Para ello analiza la obra gráfica del artista que lo acompañaba, Raj Man Singh Chitrakar, como el primer dibujante nepalí reconocido por haberse especializado en la técnica occidental.
Precisiones sobre el pintor Pedro de Mata (1564/68-1619), discípulo de Alonso Sánchez Coello
Authors: Méndez Hernán Vicente
Published: November 2023

Hasta el presente trabajo no se había relacionado a Pedro de Mata, documentado como aprendiz de Alonso Sánchez Coello, con el homónimo pintor que trabaja en la provincia de Cáceres entre finales del siglo XVI y comienzos del XVII. La muerte de Sánchez Coello le impidió acabar con él su período de formación, que tal vez siguió con el pintor toledano, asentado en Madrid, Hernando de Ávila. En cualquier caso, su documentada presencia en Toledo a comienzos del siglo XVII ratifica los inequívocos rasgos estilísticos que le emparentan con Correa de Vivar, Morales o Ávila. Su etapa más personal la desarrollará en la década de 1590 y antes de instalar su taller definitivamente en la ciudad de Plasencia en 1599, momento a partir del cual su producción será más desigual.

This research aims to examine the application of work specialization in human resource management reviews and in islamic perspectives. This research uses a qualitative approach, by reviewing various related theories obtained through literature studies. In the effective and efficient management of human resources, the specificization of work is very important. Job specialization aims to place employees in positions that are in accordance with expertise or competence.  The specificity of the work begins with the anlisis of the position and the design of the work before the recruitment and selection process is carried out. In Islam, the specificization of work turns out to be in line with the concept of human resource management, where Islam also teaches that a job must be handed over to people who are in accordance with their skills or competencies.

Reaction of ZnCl2 and two equivalents of picolinoyl(4-ethylthiosemicarbazide), HL, in MeOH in the presence of a supporting base like Et3N results in the neutral complex [Zn(L)2] (1). A similar reaction of CoCl2, however, brings about a cobalt(III) cationic complex, which could be separated as its chloride salt  [Co(L)2]Cl (2). The spectroscopic studies and X-ray structure analyses indicate that in 1 and 2, the metal ions are octahedrally coordinated by two (Npyridine, S, N1) chelates belonging to two singly deprotonated tridentate ligands {L–}.
Littérature et cartographie. Histoire de trompe-l’œil
Authors: Ost Isabelle
Published: November 2023

Une carte peut être considérée comme une forme de trompe-l’œil : selon la Logique de Port-Royal et l’interprétation qu’en donne Louis Marin, elle constitue le paradigme même du signe, l’essence de la représentation, au point que l’on va dire devant une carte de l’Italie que « c’est l’Italie ». Toutefois elle n’est telle que parce qu’elle constitue un dispositif sémiotique construit et complexe mobilisant la faculté d’imagination et élaborée par des gestes que l’on peut qualifier de poétiques. Toutes caractéristiques qui la rapprochent de la fiction, laquelle, comme on le sait, peut produire des effets de réel puissants, analogues à ceux que génère la représentation cartographique. Dans cet article, il s’agira de déplier quelques-uns des enjeux de l’opération de représentation sur laquelle se fonde la cartographie ainsi que de montrer comment la fiction littéraire peut s’emparer de ces enjeux. Deux romans contemporains seront envisagés : Une ville de papier d’Olivier Hodasava d’une part – un récit d’enquête qui explore les pouvoirs performatifs d’un nom sur une carte – et d’autre part le roman Un monde à portée de main de Maylis de Kerangal – où il est question de peinture en trompe-l’œil qui, elle aussi, produit des effets d’optique.

Peripheral halogen atoms in multi-resonant thermally activated delayed fluorescence emitters: The role of heavy atom on intermolecular interactions and spin orbit coupling
Authors: Miranda-Salinas Hector , Wang Jingxiang , Danos Andrew , Matulaitis Tomas , Stavrou Kleitos , Monkman Andrew , Zysman-Colman Eli
Published: November 2023

Multi-resonant thermally activated delayed fluorescence materials (MR-TADF) can show narrow-band emission with high photoluminescence quantum efficiency, desirable for applications in organic light emitting diodes (OLEDS). However, they frequently suffer from slow reverse intersystem crossing (RISC) compared to established donor-acceptor TADF emitters, leading to severe device efficiency roll-off at high exciton densities. Introducing heavy atom effects (HAE) by core-substitution has been previously shown to enhance spin orbit coupling and thus RISC in MR-TADF emitters, frequently with oxygen atoms replaced by isoelectronic sulfur or selenium. Here, we explore an alternate HAE strategy using peripheral halogenation of the MR-TADF DiKTa core, comparing tBr-DiKTa and dBr-tBu-DiKTa with non-halogenated Mes3-DiKTa. The two brominated emitters demonstrate improved kRISC because of the HAE, while the rate appears to improve by an additional order of magnitude in mCP host, because of intermolecular (guest-host) interaction. Despite the beneficial hetero-intermolecular interactions, strong homo-intermolecular interactions result in enhanced non-radiative pathways and lower photoluminescence quantum yields. OLEDs of dBr-tBu-DiKTa hence showed comparable EQEmax with Mes3-DiKTa (21%) and improved efficiency roll-off until 500 cd m-2, although with accelerated roll-off beyond a critical current density. Together with comparisons in less strongly doped devices, these results show that the HAE provided by peripheral halogens improves the device performance up to 500 cd m-2, but also support detrimental intermolecular interactions that dominate at higher device currents.

We present a formalism of a neural network encoding of bonded interactions in molecules. This intramolecular encoding is consistent with models of intermolecular interactions previously designed by this group. Variants of the encoding fed into a corresponding neural network may be used to economically improve representation of torsional degrees of freedom in any force field. We test the accuracy of the reproduction of the ab initio potential energy surface on a set of conformations of two dipeptides - methyl-capped ALA and ASP - in several scenarios. The encoding, either alone or in conjunction with an analytical potential, improves agreement with ab initio energies on par with that of other neural network-based potentials. Using the encoding and neural nets in tandem with an analytical model places the agreements firmly within ‘chemical accuracy’ of ± 0.5 kcal/mol.
Electrocatalytic Asymmetric Nozaki–Hiyama–Kishi Decarboxylative Coupling: Scope, Applications, and Mechanism
Authors: jiang baiyang , Gao Yang , Friede Nathan , Hunter Arianne , Boucher Dylan , Minteer Shelley , Sigman Matthew , Reisman Sarah , baran phil
Published: November 2023

The first general enantioselective alkyl-Nozaki-Hiyama-Kishi (NHK) coupling reactions are disclosed herein by em-ploying a Cr-electrocatalytic decarboxylative approach. Using easily accessible aliphatic carboxylic acids (via redox-active esters) as alkyl nucleophile synthons, in combination with aldehydes and enabling additives, chiral secondary alcohols are produced in good yield and high enantioselectivity under mild reductive electrolysis. This reaction, which cannot be mimicked using stoichiometric metal or organic reductants, tolerates a broad range of functional groups, and is successfully applied to dramatically simplify the synthesis of multiple medicinally relevant structures and natural products. Mechanistic studies revealed that this asymmetric alkyl e-NHK reaction was enabled by using catalytic tetrakis(dimethylamino)ethylene (TDAE) , which acts as a key reductive mediator to mediate the electrore-duction of the CrIII/chiral ligand complex.
Solid-state lateral proton conduction via solid-supported biological membranes reveals the role of membrane structure and bound water in proton transport
Authors: Ramanthrikkovil Variyam Ambili , Stolov Mikhail , Feng Jiajun , Amdursky Nadav
Published: November 2023

Lateral proton transport (PT) on the surface of biological membranes is a fundamental biochemical process in the bioenergetics of living cells, but a lack of available experimental techniques has resulted in a limited understanding of its mechanism. Here, we introduce a new molecular protonics experimental approach to investigate lateral PT across membranes by measuring long-range lateral proton conduction via a few layers of lipid bilayers in a solid-state-like environment, i.e., without having bulk water surrounding the membrane. This configuration enables focusing on lateral proton conduction across the surface of the membrane while decoupling it from bulk water. Hence, by controlling the relative humidity of the environment, we can directly explore the role of water in the lateral PT process. We show that proton conduction is dependent on the amount of water and their structure, and on membrane composition, where we explore the role of the head group, the level of tail saturation, and the role of the membrane phase and fluidity. The measured PT as a function of temperature shows an inverse temperature dependency, which we explain by the desorption/adsorption of water molecules into the solid membrane platform. We explain our findings by discussing the role of percolating hydrogen bonding within the membrane structure in a Grotthuss-like mechanism.
Molecular Origin of Novichok Nerve Agents
Authors: Verhellen Jonas
Published: November 2023

Nerve gasses have a devastating effect on the human body through their inhibition of the acetylcholinesterase enzyme, a crucial part of muscle control. In this review, we focus on the molecular aspects of the infamous Novichok nerve gasses. In addition to briefly outlining their development history, we place a lot of attention for the mode of action of these poisons. Secondary effects, medical treatment and legal aspects are also briefly reviewed. This document stands out from other reviews in this field by placing a focus on the (dynamic) properties of acetylcholinesterase, and by studying novichok as a carrier of a covalent warhead. In addition, by making use of recent crystal structures, the non-covalent binding aspects of novichok are described for the first time.
The distributional predictive content of measures of inflation expectations
Authors: Mitchell James , Zaman Saeed
Published: November 2023

This paper examines the predictive relationship between the distribution of realized inflation in the US and measures of inflation expectations from households, firms, financial markets, and professional forecasters. To allow for nonlinearities in the predictive relationship we use quantile regression methods. We find that the ability of households to predict future inflation, relative to that of professionals, firms, and the market, increases with inflation. While professional forecasters are more accurate in the middle of the inflation density, households’ expectations are more useful in the upper tail. The predictive ability of measures of inflation expectations is greatest when combined. We show that it is helpful to let the combination weights on different agents’ expectations of inflation vary by quantile when assessing inflationary pressures probabilistically.

Automatisierte Wissenskommunikation
Authors: Holste Alexander
Published: November 2023

The use of self-adaptive, AI/LLM-based machines is currently disruptively changing the subject area of multilingual specialist communication research. The discipline runs the risk of no longer being able to grasp the new developments through its current models and instruments and thereby marginalizing itself. Alexander Holste's model of automated knowledge communication responds to this challenge: It represents the cognitive-emotive construction of specialist knowledge by a situated knowledge actor in exchange with a language-processing machine. The model of this habilitation thesis is based on an impressive overview of the research discourse and integrates approaches from cybernetics, sociology of technology and media psychology. In a forward-looking way, it offers a program for the further development of specialist communication research towards knowledge orientation and the role of increasingly automated machines - automated knowledge communication.

Durante a pandemia, os professores de todas as instituições, públicas ou privadas, se viram desafiados frente à necessidade de utilizarem recursos tecnológicos e estratégias de ensino que se opusessem às tradicionais. Dentre as possibilidades, estão as chamadas metodologias ativas (MA), que visam uma participação ativa dos alunos durante todo o processo de ensino e aprendizagem. Sendo assim, esse estudo objetivou compreender quais concepções de professores de Química atuantes em escolas públicas e privadas acerca das MA e tecnologias digitais (TD) e se existem semelhanças e/ou diferenças entre elas, bem como se os docentes receberam formações para utilizarem essas estratégias metodológicas e recursos pedagógicos durante o Ensino Remoto Emergencial. Para tanto, adotou-se como referencial teórico as ideias de Moran e Valente sobre as MA e TD e a abordagem adotada foi qualitativa. Entrevistou-se dez professores de Química (cinco da rede pública e cinco da rede privada) atuantes em escolas localizadas no interior do Estado de São Paulo. Os dados foram submetidos à análise de conteúdo de Bardin, optando-se pela análise lexical no software Iramuteq e os resultados evidenciaram que os docentes possuem concepções semelhantes quanto às MA e TD, todavia, não receberam formação para atuarem nas aulas remotas. Ressalta-se que, este artigo apresenta aspectos importantes, como as concepções desses professores sobre MA e TD e algumas dificuldades que enfrentaram durante a pandemia, que podem ser levados em consideração na elaboração de cursos de formação docente sobre estratégias metodológicas ativas e tecnologias.
Maximum likelihood estimation of continuous-time non-homogeneousMarkov chains with time-dependent intensity and covariates
Authors: Surya Budhi
Published: November 2023

This paper presents elementary proofs on distributional properties of sample paths of continuous-time non-homogeneous Markov chain stated in Section 8.9 of Iosifescu(1980). The results are used to develop likelihood function of continuously observed realizations of Markov chains for general transition intensity matrix. It verifies and elaborates the formula (2) in Andersen and Keiding(2002) for the likelihood function of non-homogeneous Markov chain. Using finite-difference discretization of the Kolmogorov backward equation, an application of implicit Euler method shows that the transition probability matrix is explicit in terms of the intensity matrix. The solution coincides with the product integration of Aalen and Johansen(1978) and Andersen et al.(1995). In particular, it takes an explicit form of an exponential matrix. Score function and observed information matrices are derived explicitly in terms of matrix tensor notations. Thanks to explicit forms of score function and information matrix a fast convergence Newton-Raphson method is presented for ML recursive estimation of piecewise constant transition intensity and multivariate regression coefficient.

Published: November 2023

With the development of economic globalization, mobile network and media technology are developing rapidly. Media information is manufactured and disseminated at any time, and people can understand global information more conveniently with the help of media. At the same time, false, violent, pornography, and other negative information are also spreading rapidly in various media, and college students in the new era are in urgent need to improve their media literacy. This study explores the current situation of college students’ media literacy level, and explores the improvement path from the three levels of college students, universities, and the government, with the hope to provide ideas for the media literacy of college students in the new era.

Published: November 2023

Este artigo apresenta resultados de um estudo que tem como objetivo conhecer e analisar o potencial de mercados locais ou de cadeia curta de alimentos orgânicos, produzidos de forma agroecológica, por agricultores familiares em sistemas agroalimentares sustentáveis, no município de Rolante-RS. A pesquisa tem uma abordagem qualitativa e classifica-se quanto a seus objetivos como descritiva-exploratória. Para a coleta de dados foram realizadas entrevistas semiestruturadas com agricultores familiares e representantes de entidades ligadas ao meio rural local. Os resultados evidenciam a existência, sob o viés dos sistemas agroalimentares sustentáveis, de uma feira de alimentos orgânicos e agroecológicos, da comercialização de cestas de produtos orgânicos e do Grupo Jaracatiá. Estas iniciativas visam formar um coletivo cada vez maior de produção e consumo de alimentos orgânicos, no intuito de incentivar a agricultura familiar e promover a aproximação entre consumidores e produtores. Estes espaços de produção, comercialização e compartilhamento de experiências contam com propriedades já certificadas via organismo participativo de avaliação da conformidade orgânica (OPAC) pela Rede Ecovida de Agroecologia. A dinâmica neo-rural também se faz presente na realidade local, os quais correspondem a uma migração urbana para o rural, buscando desenvolver projetos pluriativos e diferenciados frente ao modelo hegemônico de agricultura. Por fim, reitera-se a importância do desenvolvimento e expansão produtiva por meio de sistemas agroalimentares sustentáveis, frente a um cenário de insegurança alimentar e degradação ambiental cada vez mais presente na atual realidade brasileira.
Potencial de desenvolvimento regional através do reaproveitamento dos resíduos do beneficiamento do arroz no Rio Grande do Sul

O estado do Rio Grande do Sul é o maior produtor e beneficiador de arroz no país, liderando também a geração de resíduos sólidos do beneficiamento de arroz. Os resíduos do beneficiamento configuram um problema para as empresas devido aos custos e dificuldades associadas à correta destinação. O reaproveitamento de resíduos é uma solução sustentável para essa questão, diminuindo os impactos ambientais e econômicos decorrentes da sua produção, sendo uma oportunidade para o desenvolvimento da agroindústria local, através da agregação de valor na cadeia, com potenciais impactos sociais. Nesse contexto, este trabalho tem como objetivo uma análise para o potencial de reaproveitamento dos resíduos do beneficiamento do arroz no Estado através da caracterização do beneficiamento, análise da concentração desse mercado e mapeamento da disponibilidade desses resíduos. Os resultados obtidos mostram uma estrutura de mercado concorrencial entre as agroindústrias do setor e revelam que existe abundante disponibilidade dos resíduos do beneficiamento no Estado, os quais encontram-se disponíveis de forma descentralizada em pequenas e grandes empresas. Esses resultados apontam para o grande potencial de reaproveitamento dos resíduos na geração de energia e novos produtos regionalmente, promovendo o desenvolvimento das regiões com emprego, renda e sustentabilidade. A seleção de rotas tecnológicas que permitam o adequado aproveitamento dos resíduos localmente é o principal desafio para o desenvolvimento desse setor. As rotas termoquímicas destacam-se pela sua simplicidade, baixo custo e possibilidade de serem integradas aos processos térmicos das próprias usinas de beneficiamento de arroz.
Texts and Tasks in Indonesian Language Textbooks: Do They Support Indonesian Students in the International Reading Literacy Test?

Several international tests on reading literacy consistently showed poor scores for Indonesian students. Textbooks are one of the teaching tools that can contribute to the development of students’ reading literacy. However, no research has examined textbooks’ capacity to develop students’ reading literacy skills, especially those assessed on international tests. The current study investigated the carrying capacity of texts and tasks in Indonesian language textbooks to develop students’ reading literacy skills, particularly those evaluated on international tests. The data were obtained from six Indonesian language textbooks used by junior and senior high school students in Indonesia. These textbooks are officially recommended by the government and are widely used in middle schools in Indonesia. The content analysis combined with the performance framework in the International Student Assessment was used to reveal the text and task dimensions of the Indonesian Language textbooks. The results of the study show that in the aspect of text, textbooks have conformity with the international test, but are weak in infographics which are not problematic. Likewise, the underlying contexts of the texts are not evenly distributed. In the task aspect, the dominant cognitive processes are to search for and locate information, but are limited in understanding, evaluating, and reflecting on the contents of the text. The response format is dominated by essay-type tests that do not adequately account for objective tests. From this, it can be concluded that the texts and tasks of the Indonesian textbooks do not correspond to the texts and tasks of the international reading literacy tests. This study recommends the need for adjustments in establishing guidelines for developing and evaluating textbooks to develop students’ reading literacy at the international level.
