Authors: Garghate Rutuja , Choudhari Dr. Sonali
Published: February 2024

Background One of the six elements that constitute the framework of the World Health Organization System is the delivery of health care. To tracks the development of healthcare service delivery, it is vital to focus on its dimensions. The objective of the current learning is to evaluate the quality of healthcare provided at the lowest level in the Wardha District. Methods A community-based cross-sectional study will be conducted in the rural area around all the sub-centers of Wardha District. A semi-structured questionnaire will be used to assess the sociodemographic profile and associated factors, namely, service delivery, service provision, and facility assessment. Study implications This study will help formulate policies that will inculcate grass-root-level health care services to gain insight into how much services need to be improved and its implications for everyone in the community. Its significance in public health will pave the way for service screening and testing of healthcare delivery systems. Additionally, it will show that the system for delivering healthcare performs better. Future research should concentrate on identifying localized deficiencies and developing console indicators to estimate healthcare delivery systems objectively.
Enter the Matrix: Fibroblast-immune interactions shape ECM deposition in health and disease.
Authors: Altieri Anthony , Visser Grace V. , Buechler Matthew B.
Published: February 2024

Fibroblasts, non-hematopoietic cells of mesenchymal origin, are tissue architects which regulate the topography of tissues, dictate tissue resident cell types, and drive fibrotic disease. Fibroblasts regulate the composition of the extracellular matrix (ECM), a 3-dimensional network of macromolecules that comprise the acellular milieu of tissues. Fibroblasts can directly and indirectly regulate immune responses by secreting ECM and ECM-bound molecules to shape tissue structure and influence organ function. In this review, we will highlight recent studies which elucidate the mechanisms by which fibroblast-derived ECM factors (e.g., collagens, fibrillar proteins) regulate ECM architecture and subsequent immune responses, with a focus on macrophages. As examples of fibroblast-derived ECM proteins, we examine Collagen Triple Helix Repeat Containing 1 (CTHRC1) and Transforming Growth Factor-β-inducible protein (TGFBI), also known as BIGH3. We address the need for investigation into how diverse fibroblast populations coordinate immune responses by modulating ECM, including the fibroblast-ECM-immune axis and the precise molecular mediators and pathways which regulate these processes. Finally, we will outline how novel research identifying key regulators of ECM deposition is critical for therapeutic development for fibrotic diseases and cancer.

Published: February 2024

Background Following the signing of the “Final Agreement for the Termination of the Conflict” in Colombia, an unprecedented boost for tourism is observed, promoting rural development and environmental protection. In the academic realm, Colombian universities offer tourism training programs to develop professionals with skills in management, sustainability, and technology. Methods Information is gathered from the Scopus database on tourism trends and from the National Information System for Higher Education (SNIES) on academic programs in tourism in Colombia until 2022. Geographical maps are employed to visualize the global scope of publications in Scopus and the locations of programs in Colombia. Text mining is used on Scopus abstracts and profiles of Colombian programs, generating word density graphs, frequency tables, and word clustering graphs. Results 707 articles from Scopus originating from 86 countries are selected, and 46 profiles of Colombian universities with tourism programs in 19 regions are compiled. Maps and tables demonstrate the geographical location of article density globally and of universities in Colombia. Word clouds, frequency tables, and dendrograms are generated using the abstracts and profiles. Conclusions Text mining analysis reveals similarities and differences between research and education in tourism in Colombia. There is convergence in management and development, reflecting aligned interests in both datasets. Words like ethics and sustainability indicate a shared commitment to a responsible perspective in the sector. Scopus emphasizes research, while Colombian universities prioritize practical training, especially in tourism management. This difference raises questions about the impact on graduates’ preparedness and their contribution to tourism development in Colombia. The geographical location of programs in Colombia shows a clear connection between academia and the tourism sector, facilitating synergies and continuous improvements.

Published: February 2024

Objective To analyze the perception of the administrative department of a municipality regarding public management. Method Qualitative approach through interviews. The sample consisted of 30 employees from the administrative department of a municipality in Peru. Results It was found that the employees seem to have a clear understanding of the applied public management model and the organization of the administrative area. Responses regarding the management of financial, human, and material resources vary in accuracy and detail, suggesting a possible lack of knowledge in some areas. It is important to enhance communication clarity on these topics and provide precise information to ensure effective and transparent management within the municipality. Conclusion Municipality employees demonstrate an understanding of their roles and face challenges in teamwork and bureaucracy. There is some confusion regarding the “New Public Management” and a lack of knowledge in resource management. Improving training, streamlining procedures, and fostering team participation in planning are crucial aspects. Furthermore, implementing periodic assessments is recommended to enhance administrative efficiency.

Protocol for a prospective comparative randomized clinical study for the comparison of two different doses of dexmedetomidine with bupivacaine in pediatric caudal anesthesia for infraumbilical surgeries in a tertiary hospital in central India
Authors: Geetha Sindhuja Boddeda , Chaudhary Neeta
Published: February 2024

Background Pediatric caudal anesthesia is a well-established technique for providing intraoperative and postoperative pain relief in children undergoing infraumbilical surgeries. Dexmedetomidine, an α2-adrenergic agonist, has shown promise as an adjuvant to local anesthetics in caudal blocks, potentially improving the quality and duration of pain relief. This study aims to compare two doses of dexmedetomidine with bupivacaine to assess their efficacy in pediatric caudal anesthesia. Methods A prospective comparative randomized clinical study will be conducted over two years in the Department of Anaesthesiology at Jawaharlal Nehru Medical College (JNMC) and Acharya Vinoba Bhave Rural Hospital (AVBRH) in Central India. Patients aged six months to six years, with American Society of Anesthesiologists (ASA) Class 1 or 2, scheduled for infraumbilical surgeries, will be included. They will be randomly allocated to receive either Group A (1 ml/kg of 0.25% bupivacaine with 1 μ/kg dexmedetomidine) or Group B (1 ml/kg of 0.25% bupivacaine with 0.5 μ/kg dexmedetomidine) in a double-masked fashion. The primary outcome is the duration of postoperative pain relief. Secondary outcomes include intraoperative hemodynamic stability, time first to rescue analgesia, incidence of adverse effects, and patient and parent satisfaction. A cost-effectiveness analysis will also be conducted. Conclusions The study will provide insights into the efficacy and safety of different doses of dexmedetomidine in pediatric caudal anesthesia for infraumbilical surgeries. The results will guide clinical practice and inform anesthesia protocols for pediatric patients in the study setting. Registration CTRI (CTRI/2023/05/057050; 29 August 2023).

Published: February 2024

Background The larynx is a complex organ for voice production, and respiration consists of a series of cartilages, membranes, muscles, and joints with a considerable range of flexibility and mobility. Understanding the laryngeal framework is important for various professionals, including phoneticians, speech therapists, oncologists, and oto-rhino-laryngologists. The goal was to measure the piriform sinus, epiglottis, and thyroid cartilage in our sample population. Methods This study included 22 adult embalmed cadavers available in the Department of Anatomy. Dimensions were measured using a digital Vernier caliper. Results The mean height of the thyroid laminae was 27 ± 1.4 mm at the right side and 25.5 ± 1.4 mm at the left side. Mean width of the thyroid lamina was 27.1 ± 1.3 mm at the right side and 27.4 ± 0.9 mm at the left side. The mean thickness of thyroid cartilage was found to be 4.4 ± 0.4 mm and 3.9 ± 0.5 mm over the right and left sides. The mean length, width and thickness of the epiglottis were 29.1 ± 0.5 mm, 22.2 ± 0.6 mm and 2.6 ± 0.3 mm correspondingly. The height, width and thickness of the right piriform sinus were 25 ± 0.5 mm, 14.2 ± 0.5 mm and 12.6 ± 0.5 mm, the same parameters were 25.3 ± 1.3 mm, 15.1 ± 0.7 mm and 13.3 ± 0.4 mm for the left side. Conclusions The morphometric data reported in this study are enlightening for clinicians involved in laryngeal and endoscopic procedures. Some of the parameters showed statistically significant differences between the right and left sides (p<0.05). However, the limitation is that the smaller sampler size being studied in this anatomical research, and the data will only be accurate with a larger sample size.
Wings of Change: aPKC/FoxP-dependent plasticity in steering motor neurons underlies operant self-learning in Drosophila
Authors: Ehweiner Andreas , Duch Carsten , Brembs Björn
Published: February 2024

Background Motor learning is central to human existence, such as learning to speak or walk, sports moves, or rehabilitation after injury. Evidence suggests that all forms of motor learning share an evolutionarily conserved molecular plasticity pathway. Here, we present novel insights into the neural processes underlying operant self-learning, a form of motor learning in the fruit fly Drosophila. Methods We operantly trained wild type and transgenic Drosophila fruit flies, tethered at the torque meter, in a motor learning task that required them to initiate and maintain turning maneuvers around their vertical body axis (yaw torque). We combined this behavioral experiment with transgenic peptide expression, CRISPR/Cas9-mediated, spatio-temporally controlled gene knock-out and confocal microscopy. Results We find that expression of atypical protein kinase C (aPKC) in direct wing steering motoneurons co-expressing the transcription factor FoxP is necessary for this type of motor learning and that aPKC likely acts via non-canonical pathways. We also found that it takes more than a week for CRISPR/Cas9-mediated knockout of FoxP in adult animals to impair motor learning, suggesting that adult FoxP expression is required for operant self-learning. Conclusions Our experiments suggest that, for operant self-learning, a type of motor learning in Drosophila, co-expression of atypical protein kinase C (aPKC) and the transcription factor FoxP is necessary in direct wing steering motoneurons. Some of these neurons control the wing beat amplitude when generating optomotor responses, and we have discovered modulation of optomotor behavior after operant self-learning. We also discovered that aPKC likely acts via non-canonical pathways and that FoxP expression is also required in adult flies.
A Post-Fellowship Support Framework for Rural Doctors: the Queensland experience
Authors: Dhupelia Dilip , Van Erp Ansmarie , Collins James , Sen Gupta Tarun
Published: February 2024

Background International workforce shortages have prompted many initiatives to recruit, train and retain rural doctors, including Australia’s emerging National Rural Generalist Pathway. This project explored an important component of retention, rural doctors' post-Fellowship support needs, to develop and validate a post-Fellowship support framework. There has been considerable international attention on social accountability in medical education and how medical schools and other institutions can address the needs of the communities they serve. The recognition that rural and remote communities globally are underserved has prompted numerous educational approaches including rurally focused recruitment, selection, and training. Less attention has been paid to the support needs of rural doctors and how they can be retained in rural practice once recruited. Methods The project team reviewed international and Australian rural workforce and medical education literature and relevant policy documents to develop a set of guiding principles for a post-Fellowship support framework. This project utilised a mixed methods approach involving quantitative and qualitative methodologies. A range of rural doctors, administrators, and clinicians, working in primary and secondary care, across multiple rural locations in Queensland were invited to participate in interviews. Thematic analysis was undertaken. Results The interviews validated ten interconnected guiding principles which enabled development of a grounded, contextually relevant approach to post-Fellowship support. This framework provides a blueprint for a retention strategy aiming to build a strong, skilled, and sustainable medical workforce capable of meeting community needs. Conclusions The ten principles were designed in the real-world context of a mature Queensland Rural Generalist Pathway. Four themes emerged from the inductive thematic analysis: connecting primary and secondary care; valuing a rural career; supporting training and education; and valuing rural general practice. These themes will be used as a basis for engagement and consultation with rural stakeholders to develop appropriate retention and support strategies.

Grouping sounds into evolving units for the purpose of historical language comparison
Authors: List Johann-Mattis , Hill Nathan W. , Blum Frederic , Juárez Cristian
Published: February 2024

Computer-assisted approaches to historical language comparison have made great progress during the past two decades. Scholars can now routinely use computational tools to annotate cognate sets, align words, and search for regularly recurring sound correspondences. However, computational approaches still suffer from a very rigid sequence model of the form part of the linguistic sign, in which words and morphemes are segmented into fixed sound units which cannot be modified. In order to bring the representation of sound sequences in computational historical linguistics closer to the research practice of scholars who apply the traditional comparative method, we introduce improved sound sequence representations in which individual sound segments can be grouped into evolving sound units in order to capture language-specific sound laws more efficiently. We illustrate the usefulness of this enhanced representation of sound sequences in concrete examples and complement it by providing a small software library that allows scholars to convert their data from forms segmented into sound units to forms segmented into evolving sound units and vice versa.

Published: February 2024

The study identifies the place of leasing in the Russian financial system, and evaluates the dependence of the volume of new business in the leasing industry on such macroeconomic indicators as the GDP growth rate and the level of the key rate in the country. The volume of a new business is as a numerical indicator showing the amount of transactions concluded over a certain period for which purchased equipment was leased. This information might be useful for the leasing companies to set goals for the volume of leasing projects, based on the macroeconomic situation, and to assess their risks. The object of the study is the Russian leasing market (a set of leasing projects), including the relationship of leasing companies with other financial institutions — banks and insurance companies; the subject is the volume of new business.
conflicto entre la inmunidad soberana y la carga de los buques hundidos: el rol de la equidad
Authors: Arjona Hernández Noelia
Published: February 2024

La adquisición colonial expiró con la disolución de los imperios coloniales. El principio de inmunidad no debe permitir la ampliación de ninguno de ellos. Los principios que permitían a los Estados subyugar, explotar y, en ciertos casos, perpetuar el genocidio para saquear los recursos de territorios extranjeros han evolucionado desde entonces. Este artículo explora cómo el principio jurídico internacional de la equidad puede influir en el conflicto entre la inmunidad soberana y la carga de los buques hundidos a través de la condena de los abusos de soberanía en sucesivos instrumentos de derecho convencional, estatutos de tribunales penales internacionales y la práctica de los Estados.
usos de opiniões dissidentes da Corte Internacional de Justiça no caso ‘changri-lá’ pelo supremo tribunal federal
Authors: Fonseca Melo Rafael
Published: February 2024

O presente artigo tem como objetivo analisar a maneira através da qual opiniões individuais e dissidentes de juízes da Corte Internacional de Justiça podem ser usadas por outras cortes e tribunais para o desenvolvimento do direito internacional. Para isso, faz-se um estudo de caso das referências feitas pelo Supremo Tribunal Federal no julgamento do caso “Changri-lá” à opinião dissidente do juiz Cançado Trindade no caso das Imunidades jurisdicionais dos Estados (Alemanha v. Itália). Identifica-se, a partir disso, duas formas de uso estratégico distintas: um uso formal - concentrado na autoridade do pronunciamento - e um uso material - concentrado na reprodução do raciocínio jurídico da opinião. Conclui-se que o voto do ministro Edson Fachin demarca um distanciamento material em relação ao raciocínio da opinião, privilegiando o seu uso formal. Por fim, questiona-se as implicações dessa estratégia.

Mispricing and Algorithm Trading
Authors: Zhang Lihong , Zhang Xiaoquan (Michael)
Published: February 2024

This study relaxes the efficient market hypothesis by introducing a model that accounts for initial mispricing and explores the effects of algorithmic trading. The research finds that algorithmic strategies can cause significant market volatility and affect financial stability, particularly when they amplify overpricing, leading to bubbles and crashes. Key insights include: Initial mispricing is crucial for algorithmic trading to impact market prices. Market reactions vary with the direction of the trading strategy relative to the asset’s true value. Informed traders can benefit from mispricing, whereas noise traders typically incur losses.

Policy implications suggest that algorithmic trading is not universally harmful; its effects depend on the alignment of trading strategies with accurate pricing. The study advises regulators to differentiate between stabilizing and destabilizing trading practices. For traders, the research highlights the importance of adaptive strategies that help correct mispricing to ensure long-term profitability and market health. This research advances our understanding of algorithmic trading’s dual potential and informs the development of more nuanced financial regulations and trading strategies.

Uma correção nos dados de matrículas de alunos com altas habilidades/superdotação de 2019:
Authors: De Oliveira Lívio Luiz Soares
Published: February 2024

Este artigo, que usa como metodologia a análise qualitativa e quantitativa de dados, tem como objetivo responder à causa do explosivo aumento do número de matrículas de alunos com altas habilidades/superdotação (AH/SD) em 2019, comparativamente ao ano de 2018, segundo os dados divulgados no Censo Escolar e na Sinopse Estatística da Educação Básica. Conforme demonstrado no artigo, o número de matrículas de alunos com AH/SD para São Paulo, em 2019, não foi de 32.638 registros, mas de apenas 1.932. Assim, o número dessas matrículas para o Brasil, no mesmo ano, não foi 54.359 e, sim, 23.653 registros. Este superdimensionamento ocorreu por problemas no cômputo dos dados pelas Diretorias de Ensino da Secretaria Estadual de Educação do Estado de São Paulo. Essas correções e atualizações ainda não foram feitas no Censo Escolar nem na Sinopse Estatística da Educação Básica. Neste contexto, o artigo aponta algumas fragilidades, falhas e problemas com os sistemas de coleta e de registros de dados para o cômputo dos números de matrículas de alunos com AH/SD no Censo Escolar. Ainda discute algumas medidas que poderiam ser adotadas para melhorar a eficiência, qualidade e precisão desses sistemas.
As competências da cultura:
Authors: Cordeiro Albert
Published: February 2024

Neste artigo debatemos como a diversidade cultural é abordada na Base Nacional Comum Curricular. O trabalho foi construído a partir da análise do documento, seguindo as orientações da pesquisa documental e em diálogo com parte da bibliografia crítica do campo do currículo (Silva, 2008; Cury, Reis, Zanardi, 2018). Averiguamos a recorrência do tema da cultura nas competências gerais da educação básica e nas demais competências previstas pelas diferentes áreas do conhecimento estabelecidas pela Base, construindo o discurso que diz se tratar de um documento que visa construir currículos interculturais na educação básica. Contudo, concluímos que a própria noção de competência é uma abordagem que reforça e referenda o ideário neoliberal que, por princípio, é monocultural. Deste modo, a suposta valorização da diversidade cultural presente na BNCC é na verdade uma expressão do que Tubino (2005) chama de interculturalidade funcional, quer dizer, ações que dizem promover a tolerância, mas sem tocar nas causas das assimetrias sociais e culturais hoje vigentes, o que torna o diálogo intercultural inautêntico.
O estudo do currículo na formação inicial de professores de química da UFJF
Authors: Cerqueira de Aragão Priscilla Lúcia , Afonso Andréia Francisco
Published: February 2024

O currículo é parte essencial do processo de ensino e de aprendizagem e, por isso, deve ter suas bases fundamentadas durante sua elaboração e aplicação. A fundamentação, as concepções e teorias das quais os currículos escolares estão imbuídos, interferem na prática docente. Dessa forma, é na formação inicial que os licenciandos devem encontrar espaços para refletir, discutir e pensar em propostas curriculares que se articulem com as demandas das instituições escolares. Para investigar quais são esses espaços, analisamos as disciplinas que apresentam indícios de que o estudo, a reflexão e a discussão sobre currículo podem acontecer e averiguamos como se consolidaram ao longo das reformas curriculares. Para isso, realizamos uma pesquisa qualitativa, tendo como objeto de estudo, os fluxogramas, ementas e conteúdos das disciplinas dos cursos presenciais de licenciatura em química da Universidade Federal de Juiz de Fora. Os resultados apontaram que no decorrer dos anos, houve disciplinas com potencial para o estudo do currículo, contudo, apenas uma se dedica exclusivamente ao estudo desse documento. Esses dados indicam que é preciso ampliar os espaços para o estudo dos currículos da educação básica, assim como para a construção dos saberes curriculares dos licenciandos em química.
Aterrando políticas obscurantistas:

Published: February 2024

Em virtude do reflexo gerado nos últimos meses a partir da implementação do Novo Ensino Médio (NEM) no país, este ensaio teórico tem por objetivo traçar diálogos entre a filosofia latouriana e as conversas complicadas sobre currículo, tecidas por William Pinar, dando base para pensar em formas de orientação perante a desterritorialização ampliada pelas mutações climáticas e aos impactos gerados pelas políticas públicas em nosso saber-fazer-artístico docente. O cenário político atual, marcado por manifestações e pela protocolação do PL n. 2.601/2023, abriu espaço para pensar em currículos outros, construídos a partir do diálogo entre seres-terrestres, partindo de suas experiências de vida e saberes produzidos com/no/sobre o ambiente em que (co)habitam. Ao propor, neste artigo, uma reconstrução do passado indolente, marcado pela imposição de políticas públicas nefastas a partir de interesses das elites obscurantistas, esperançamos a (re)construção de um currículo pautado em geo-histórias, orientando os terrestres frente a mutações climáticas e os politizando para a superação de uma globalização individualista e segregante.

Pensar nas trajetórias dos professores e educadores sociais caiçaras da cidade de Iguape – São Paulo (SP) é refletir sobre os caminhos percorridos pelos povos do campo que retiram da terra e de suas tradições ancestrais força para prosseguir lutando por melhores condições de vida, educação, cultura e cidadania. O problema desse artigo traz a seguinte indagação: como se apresentam as trajetórias dos professores e educadores sociais caiçaras do município de Iguape - SP? Buscando responder, tivemos como objetivo analisar a trajetória de professores e educadores sociais caiçaras no município de Iguape - SP. As comunidades tradicionais caiçaras estão situadas nos litorais dos Estados do Paraná, São Paulo e Rio de Janeiro, e apresentam modos de vida semelhantes por realizarem o mutirão de fandango como meio de uma organização social e produzir uma canoa utilizando um único tronco, bem como outros artefatos, num estilo parecido. Além disso, as populações caiçaras resultam da confluência dos indígenas, europeus e africanos que moldam, ao longo dos séculos, as faces dos brasileiros. Esta pesquisa foi fundamentada no materialismo histórico-dialético, no viés qualitativo, coletamos os dados por meio de entrevista semiestruturada. As comunidades tradicionais caiçaras pertencem ao grupo que compõe a educação do/no campo, contudo existe uma peculiaridade única que distinguem das outras comunidades campesinas, cujas características dizem respeito a tirar também do mar, por meio da pesca, o seu sustento.
Educação de Jovens e Adultos em um mundo híbrido:
Authors: Baptista Anderson José Lisboa , Teles Jorge
Published: February 2024

A pandemia de Covid tornou a relação com o mundo digital mais intensa e desafiadora. Esse debate já ocorre na educação, porém precisa ser mais explorado na educação de jovens e adultos (EJA). O presente ensaio visa refletir sobre a EJA e os desafios da inclusão digital no mundo contemporâneo, à luz das dificuldades estruturais e tecnológicas que atravessam esta modalidade da educação básica. A pesquisa se baseia em método qualitativo, com análise bibliográfica e de dados secundários, valendo-se de abordagem crítica em diálogo com teorias de Arendt (2014) sobre a condição humana e a produção sobre letramento e tecnologias digitais de informação e comunicação (TDICs) na educação, com centralidade nas categorias humanização e letramento digital. As reflexões apontam que a inclusão digital para ser real deve ir além do simples acesso às tecnologias. Assumir a inclusão assente em efetivo letramento digital na EJA é, sobretudo, um projeto humanizador.

Never fear when a rabbit stasis patient is near
Authors: Morrison Cassie
Published: February 2024

Managing a gut stasis rabbit can be very challenging for a veterinary team. The goal should be to resolve the acute, potentially life-threatening condition, to then allow the veterinary surgeon to diagnose the cause of why the gastrointestinal stasis has occurred in the first place. Given the nature of these patients and how high maintenance they can be, a lot of the monitoring and care falls on the veterinary nurse. The veterinary nurse becomes the eyes and ears for the veterinary surgeon and the information that is passed on to them can impact the treatment plan of the patient. Some veterinary nurses may find this daunting and, certainly in the author's own practice, some nurses enjoy working with rabbits more than others. The aim, as a cohesive team, has been to create a protocol which everyone can use to standardise how stasis patients are treated and boost the confidence of less experienced team members.
Nursing a patient with feline urethral obstruction
Authors: Mistry Krishna , O'Byrne Evelyn
Published: February 2024

Feline urethral obstruction is a potentially life-threatening condition. The maintenance and monitoring of the patient's electrolyte levels and fluid balance, and urinary catheter management, as well as an individual nursing care plan is vital for a positive patient outcome. The communication between the veterinary surgeon, veterinary nurse and client can create a well-rounded holistic approach to each patient.
RANKL, OPG, and RUNX2 expression and epigenetic modifications in giant cell tumour of bone in 32 patients

Published: February 2024

Aims

The present study investigated receptor activator of nuclear factor kappa-Β ligand (RANKL), osteoprotegerin (OPG), and Runt-related transcription factor 2 (RUNX2) gene expressions in giant cell tumour of bone (GCTB) patients in relationship with tumour recurrence. We also aimed to investigate the influence of CpG methylation on the transcriptional levels of RANKL and OPG.

Methods

A total of 32 GCTB tissue samples were analyzed, and the expression of RANKL, OPG, and RUNX2 was evaluated by quantitative polymerase chain reaction (qPCR). The methylation status of RANKL and OPG was also evaluated by quantitative methylation-specific polymerase chain reaction (qMSP).

Results

We found that RANKL and RUNX2 gene expression was upregulated more in recurrent than in non-recurrent GCTB tissues, while OPG gene expression was downregulated more in recurrent than in non-recurrent GCTB tissues. Additionally, we proved that changes in DNA methylation contribute to upregulating the expression of RANKL and downregulating the expression of OPG, which are critical for bone homeostasis and GCTB development.

Conclusion

Our results suggest that the overexpression of RANKL/RUNX2 and the lower expression of OPG are associated with recurrence in GCTB patients.

Deploying Machine Learning Methods to Predict Global Trade Patterns: The Case of Beef
Authors: Jeong Sei , Gopinath Munisamy , Kulkarni Ajay , Batarseh Feras
Published: February 2024

Highlights

Machine Learning (ML) methods are offered as an alternative to conventional techniques for understanding global commodity trade.

A formal comparison is made between ML results with those from the Poisson Pseudo Maximum Likelihood (PPML) Estimator, which is the most commonly used statistical technique for bilateral trade analysis.

PPML takes into account fixed effects and the dynamic nature of panel data to provide a better fit and higher prediction accuracy than ML in the context of in-sample forecasts.

ML methods have strengths in feature selection, better validation statistics, and stronger predictive power than PPML, especially with out-of-sample forecasts.

Abstract. In international economics, there has been a steady stream of innovations to explain patterns of trade between and among countries with emerging techniques. The most recent - Poisson Pseudo Maximum Likelihood (PPML) estimator – corrects for a potential bias caused by the large proportion of zero observations in bilateral trade data. Alternatively, this study offers Machine Learning (ML) as an option, especially in the presence of finer data on bilateral trade patterns. Using monthly and HS-6-digit (product) level data, the study finds that the main advantage of PPML is its accuracy of forecasts in-sample, but feature selection is somewhat rigid due to the inclusion of a large number of pair-wise fixed effects. ML models have the advantage in selecting features when a long list of explanatory variables is to be considered. Model validation statistics such as MAE and RMSE favor ML methods, but PPML tends to yield higher goodness of fit. In the out-of-sample context, ML has better accuracy than PPML, and a one-step walk-forward ML approach further improves the accuracy of ML forecasts. While PPML has a rich research and application history, emerging ML techniques have sufficient room for improvement in their adaptation to economic analysis.
