The Impact of Foreign Direct Investment Inflow on the Socio-Economic Upgrading of Nigeria
Authors: Ojapinwa Taiwo Victor , Akingbade Afolajimi
Published: July 2024

The research determined if the inflow of foreign direct investment has a significant impact on the socioeconomic upgrading of the Nigerian economy. Standard of living and job creation served as measures of socioeconomic development. The methodology adopted involved the use of multiple regression analysis to assess secondary time series data from 1996 to 2020 sourced from the World Bank. The study revealed that foreign direct investment inflow has a positive effect on both employment generation and standard of living. The impact on job creation was significant while that on standard of living was weak. Thus the research was able to establish a positive relationship between foreign direct investment and socio-economic development in Nigeria. It was recommended that institutional frameworks be established and supported to enable foreign investors to operate profitably in the Nigerian economy. Another suggestion was for foreign firms operating in Nigeria to be given tax incentives to augment their ability to serve as engine of socio-economic enhancement of the host economy. Finally, the Nigerian government should tackle the problems of insecurity and inflation to foster macroeconomic stability, thus attracting the inflow of foreign direct investment.

Objetivo: analizar la dinámica del empleo en Sonora durante las recesiones observadas en el período que va de 2000 a 2023. Metodología: se emplea la técnica de identificación de los ciclos económicos clásicos y los índices de difusión sincrónicos sectoriales. Resultados: la recesión de la pandemia por Covid-19 tuvo mayor propagación en comparación con las crisis previas debido a que un mayor número de sectores registraron retrocesos en la generación de empleo. El índice de difusión sincrónico sectorial alcanzó un valor de 89% y la variante ponderada llegó hasta 99%. Las actividades económicas más afectadas fueron la agricultura, servicios para empresas, hogar y personas y las industrias de la transformación y la construcción. Limitaciones: el estudio analiza la dinámica estatal, pero no indaga sobre la influencia de los choques nacionales o internacionales. Conclusiones: la medición de los impactos de las recesiones cíclicas en el mercado laboral de Sonora proporciona un insumo estadístico que permite diseñar las políticas económicas regionales para superar los episodios recesivos.

Los flujos verticales, dentro del ciclo hidrológico, son una de las variables de mayor relevancia en zona de llanura, dado que las pendientes varían entre 0 y 5%, y los flujos horizontales no son significativos. En este sentido, la evapotranspiración juega un rol fundamental en el manejo hídrico, ya que alrededor del 85% del agua que sale del sistema lo hace mediante este proceso, requiriendo una cuantificación precisa. El objetivo principal de este trabajo es calcular la evapotranspiración potencial y real (ETp y ETr) con datos de satélite y reanálisis mediante el uso de la plataforma Google Earth Engine. Para su cálculo se tomó la ecuación de Priestley-Taylor (PT) combinado con información de humedad de suelo, con una resolución espacio-temporal de 250 x 250 m cada ocho días, en la región pampeana argentina (RPA). El producto se valoró en siete estaciones de la RPA, cuyos resultados mostraron, para la ETp, un R-RMSE (error cuadrático medio robusto) de 0.5 mm d-1; un error sistemático (mediana) de 0.3 mm d-1, y el error aleatorio (RSD- desviación estándar robusta) de 0.5 mm d-1; mientras que para la ETr, estos valores son de 0.6, -0.2 y 0.5 mm d-1, respectivamente. Los resultados globales muestran que el método utilizado es una herramienta válida para caracterizar la ET en la RPA y que se puede usar para analizar su variabilidad espacio-temporal en diferentes condiciones extremas y realizar estudios ambientales aplicados.

La pequeña irrigación (PI) en México ha sido fundamental para su desarrollo agrícola. La PI surge principalmente de organizaciones de riego tradicional con autogobierno; sin embargo, la intervención del Estado reconfiguró su base autogestiva para reagruparlas “institucionalmente” como unidades de riego (UR). El objetivo de este trabajo fue caracterizar la tipología de las UR en términos de la fuente de abastecimiento de agua y su tamaño. A diferencia de los distrito de riego (DR), las UR son autogestivas y abastecidas principalmente de aguas subterráneas, y han estado marginadas de la intervención del Estado, por lo que la información sobre el inventario de las UR es limitada. Existe una gran diferenciación de las UR según su fuente de abastecimiento, tamaño y localización. Las UR se encuentran muy dispersas y predominan las UR monousuario abastecidas por aguas subterráneas operadas por usuarios independientes con limitada solidaridad hídrica, lo cual dificulta su estudio, seguimiento y apoyo.

Activated carbon assisted cobalt catalyst for hydrogen production: synthesis and characterization
Authors: Ekinci Selma , Onat Erhan
Published: July 2024

In this work, a cobalt catalyst supported by activated carbon was used to produce hydrogen through the hydrolysis of sodium borohydride (NaBH4). First, hydrochar was produced from MDF powder by hydrothermal pretreatment. Then, ideal parameters (activator percentage, activation time, baking time, and temperature) for activated carbon production were determined. The best conditions for the synthesis of activated carbon were found to be a 70% activator rate, 24 hours of activation time, 45 minutes of baking time, and 700 ⁰C temperature, according to iodine number measurements. The iodine number was measured as 929 mg/g under optimum conditions. Activated carbon (as a support) produced under optimum conditions was combined with the cobalt catalyst. DT/TGA, FT-IR, SEM, and EDX analyses were used to evaluate the catalyst's structure. Supporting material ratio, NaOH concentration, catalyst amount, and NaBH4 concentration are the variables studied in catalyst synthesis. The trials led to the identification of the optimal catalyst parameters as being 70% support material, 5% NaOH, 40 mg catalyst, and 2% NaBH4 concentration. The hydrogen production rate with the catalyst synthesized in these conditions was determined as 8592.8 ml/g.min. As a result of the hydrolysis reactions carried out at different temperatures, it was determined that the reaction was n. order and the reaction activation energy was 31.19 kJ/mol. Even after the sixth use, 100% efficiency was attained when the catalyst activity was tested repeatedly.
Salt stress and exclusion mechanism in woody plants
Authors: Güngör Banu , Kıran Sevinç , Okay Yeşim
Published: July 2024

Many fruit tree species that are widely available in the world market continue to grow and bear fruit in the face of environmental stress. The negative impact of salt stress causes fruit trees to weaken and reduce their yield and quality. However, unlike annual plants, perennial fruit trees, which are exposed to many biotic and abiotic stresses under natural conditions, have developed many complex tolerance mechanisms to maintain their vital activities. Some fruit trees that can tolerate salt stress are able to exclude salt by maintaining their physiological and biochemical activities. In this review, we share the current knowledge on salt effects and tolerance in fruit trees and assess how salt is physiologically excluded from various parts of woody plants through the interaction of environmental factors.

Authors: Işıktaş Ali , Balikoglu Fatih , Demircioğlu Tayfur Kerem
Published: July 2024

This study provides shear test results of single-lap adhesive joints with aluminum 5754-H111. To investigate the effect of adhesive thickness on joint strength in single-lap adhesive joints, three different thicknesses (0.2, 1, and 2 mm) were applied. Increasing the adhesive thickness from 0.2 mm to 1 mm and from 0.2 mm to 2 mm resulted in a reduction in shear load of roughly 36% and 44%, respectively. It has been observed that the joint strength decreases with increasing adhesive thickness in single-lap adhesive joints with aluminum 5754-H111. In addition, single-lap adhesive joints were tested at various loading rates (1, 10, and 100 mm/min), and the influence of loading speed on adhesive strength was studied. The shear load increased with the loading speed in the test results of single-lap adhesive joints.
Los mapas cognitivos de Madrid y Buenos Aires en cuatro canciones de Joaquín Sabina: experiencia de lectura colectiva en el aula universitaria

Authors: Soto Zaragoza Javier
Published: July 2024

Este trabajo analiza y valora un experimento de lectura colectiva realizado con 33 estudiantes universitarios para identificar su percepción de los mapas cognitivos de Madrid y Buenos Aires a partir de los lugares de ambas ciudades representados en cuatro canciones escritas por el cantautor español Joaquín Sabina: “Yo me bajo en Atocha”, “Caballo de cartón”, “Con la frente marchita”, y “Dieguitos y mafaldas”2. El objetivo es analizar cómo se interrelacionan en la configuración de los mapas cognitivos de ambas ciudades aspectos como su conocimiento previo por parte de los lectores, su identificación de los espacios mencionados en las canciones o los niveles de afección o desafección hacia estos. Para ello, se parte de la definición y matización del concepto de mapa cognitivo y se revisitan algunas teorías sobre la relación del lector con la ciudad y sobre la recepción textual. El análisis cuantitativo y descriptivo de los datos aportados por el test con el que se encuestó a los estudiantes revela que los lectores/oyentes de las letras de Sabina construyen con suficiencia un mapa cognitivo semántico (no gráfico) y que para ello resultan determinantes sus experiencias previas.
Temas y variaciones de la conciencia trágica: Jesús Arias y Javier Egea

Authors: Daza González Isabel
Published: July 2024

Aceptando que todo discurso crítico es una aproximación, este artículo se acerca a la obra del artista Jesús Arias, reconocido periodista, músico y compositor excepcional y, como trato de exponer, en todo y ante todo, poeta. Una tarea necesaria por cuanto se trata de un poeta que ni siquiera ha sido asumido como tal y cuya obra aparece disgregada en multitud de elementos diversos y heterogéneos (diarios, cuadernos de trabajo, libros de poemas, canciones, ensayos de diversa índole). Un conjunto complejo que, en una línea althusseriana, cobra forma y adquiere unidad al rastrear las huellas del espesor inconsciente que lo trama para contribuir –es el valor real de la crítica a decir de Juan Carlos Rodríguez– al conocimiento objetivo de su obra, a su funcionamiento a la vez consciente e inconsciente y al modo en el que su poética se entrelaza con otras voces fundamentales de su escena como la del poeta Javier Egea a partir de lo que se ha denominado conciencia trágica que ambos heredan de García Lorca.

O suicídio representa um grave desafio de saúde pública em escala mundial, resultando na perda anual de mais de 700 mil vidas, com uma incidência significativa entre a população jovem. No contexto brasileiro, a taxa de mortalidade por suicídio tem uma média de 5,23 por 100 mil habitantes. A despeito da existência de diversas diretrizes destinadas ao manejo do comportamento suicida, percebe-se a ausência de protocolos desenvolvidos sob os rigores da medicina baseada em evidências específicos para o panorama brasileiro do suicídio. Este estudo visa estabelecer diretrizes fundamentais para a intervenção junto a pacientes demonstrando comportamento suicida no Brasil. O desenvolvimento destas diretrizes contou com a participação de onze psiquiatras renomados, escolhidos pela Comissão de Emergências Psiquiátricas da Associação Brasileira de Psiquiatria (ABP) com base em sua vasta experiência e conhecimento especializado tanto na psiquiatria geral quanto no tratamento de emergências psiquiátricas. A elaboração destas diretrizes foi embasada na análise criteriosa de diversos artigos científicos, selecionados após o exame preliminar de 5362 registros. Neste suplemento procurou-se traduzir os 3 artigos das diretrizes e atualizar, sem alterar sua essência, para a língua portuguesa as informações de maior relevância clínica.

Published: July 2024

The Bun-bun River was located in a mangrove forest area in Kubu Raya Regency and empties into the sea. As the main producers at the trophic level of waters, phytoplankton has an important role in assessing river quality. This study aims to find out phytoplankton community structure including abundance, diversity, uniformity, and dominance indexs in relation to Bun-bun River quality. The observations were made in the dry and rainy seasons at three stations starting from the initial end of the mangrove forest (Station 1), the middle (Station 2), and the final end which also empties into the sea (Station 3). Sampling was carried out at three points (left edge, center, right edge). Measurements of physico-chemical factors include brightness, current velocity, temperature, pH, DO, dissolved CO2, salinity, nitrate and phosphate. Phytoplankton sampling used a 30 µm plankton net mesh size and identification down to the species level. The calculated index values include abundance, diversity, uniformity, and dominance. The Bun-bun River was characterized by brackish waters with calm surface currents (<0.1 m.s-1) and a salinity between 5.4-9.48 ppt. Dissolved CO2 levels are relatively high, namely 22-30.8 mg.L-1 in the dry season and 35.2 mg.L-1 in the rainy season. During the dry season, the pH of the water becomes slightly acidic (6.51-6.76) and relatively neutral during the rainy season (7.08-7.52). Nitrate and phosphate levels were low in both seasons and all three stations. The brightness of the water was higher in the dry season than in the rainy season (20-44 cm). A total of 52 types of phytoplankton were found belonging to four classes, namely Class Bacillariophyceae (25 species), Dinophyceae (14), Chlorophyceae (12), and Chrysophyceae (1). Phytoplankton abundance index was low to moderate. The diversity index was moderate at almost all stations except for the low at Station 3 in the rainy season. The uniformity index at Station 3 was low in the dry season but high in the rainy season, and moderate in other locations. The dominance index was high at Station 3 during the dry season and moderate at other locations. Physico-chemical factors such as salinity, dissolved CO2, nitrate and phosphate levels are most likely to influence abundance, while diversity was influenced by dominance.

Authors: Sekatskaya Ekaterina  Olegovna
Published: July 2024

The article presents the results of a theoretical analysis and empirical study of the relationship between proactive coping strategies with psychological well-being and life satisfaction. The object of the study is proactive coping among students. The subject of the study is psychological well–being, life satisfaction as predictors of proactive coping. Currently, it is noted that proactive coping makes a significant contribution to the formation of psychological health. Among the distinctive characteristics of proactive coping strategies is the assessment of future stressors, that is, the process of preadaptation. It is proactive coping that leads a person to development more than strategies to avoid failure. Accordingly, the study of the links between psychological well-being, life satisfaction and the coping process allows us to expand our understanding of the most effective coping strategies, which include proactive coping. The research method is a theoretical analysis of domestic and foreign sources, as well as empirical psychodiagnostics of 144 respondents in the age period of early and middle adulthood. According to the results of the correlation analysis, statistically significant correlations between the formation of proactive coping strategies, psychological well-being and life satisfaction are demonstrated and described. The scientific novelty lies in the identification of predictors of proactive coping behavior, in this regard, it seems relevant to search for significant relationships. It is revealed that psychological well-being, life satisfaction as personal characteristics can be considered in the perspective of further research as factors of the severity of the formation of proactive and preventive coping, abilities to meet needs and achieve goals, self-realization, having goals in life, positive self-acceptance and adequate self-esteem demonstrate a great formation of proactive coping strategies. The new data obtained may be relevant in the development of psychological support aimed at the development of proactive coping strategies among adults.
The development of methodological foundations in studying the emotional sphere of blind people in the works of Russian scholars in the pre-war period
Authors: Markelova Tat'yana Vladimirovna , SHahina Alyona Sergeevna
Published: July 2024

Researching the emotional sphere of a person is one of the fundamental tasks in modern science, involving a wide range of methods and approaches. Analyzing the emotional sphere of blind and visually impaired individuals presents a particular complexity due to the limitations and peculiarities of their sensory perception of the surrounding reality. This article covers the development of the conceptual foundations for researching the emotional sphere of people with visual impairments in the context of the work of Russian scientists. The first scientific discussions in Russia about the need for specialized analysis of the psychological aspects of blindness were expressed in the editorial article of the journal "Russian Blind" in the 1880s. While the development of foreign tiflopsychology as an independent science, related to the organization of education for children with visual impairments in special schools, began in Paris at the end of the 18th century. In the process of forming this area of knowledge, Russian researchers face the lack of methodological foundations for systematic research of the emotional sphere of visually impaired individuals. As a result, scientists propose various approaches to analyzing the emotional sphere of the blind. Some scientists try to use a metaphysical-based approach to study the emotional processes of the blind, while others suggest studying this area within the framework of a materialistic approach. As a result of such contradictions, two directions for studying the emotional sphere emerged - a mechanistic approach based predominantly on biological factors and the theory of supercompensation, explaining changes in the emotional sphere of the blind based on their social experience.

Feature Selection Techniques in Intrusion Detection: A Comprehensive Review
Authors: ALkahla Lubna , Khalaf Hussein Maher , Alqassab Asmaa
Published: July 2024

This investigation aims to explore previous research on the implementation of feature selection in intrusion detection. Feature selection has demonstrated its ability to enhance or sustain comparable classification accuracy levels for intrusion detection systems, while simultaneously improving classification efficiency. The evaluation includes an assessment of filter-based, wrapper-based, and hybrid feature selection techniques. Given that Big Data challenges can affect intrusion detection, feature selection’s classification efficiency can aid in lowering computing requirements. Older KDD intrusion detection datasets have received considerable attention in previous feature selection research. Consequently, researchers need more high-quality datasets that are available to the general public.

Новизна исследования заключается в обобщении данных об одном из основных ландшафтных кодов «земля/тайга» в культурной памяти потомков древних охотников и рыболовов, кочевавших на территории Восточной Сибири. Цель работы – рассмотреть значимость полифункционального образа «земля/тайга» у лесных юкагиров верхней Колымы. Задачи: проанализировать пространственно-временные представления, животный мир, звуковую символику, декоративно-прикладное искусство. Культовое отношение к земле/тайге определяется на материале фольклора, зафиксированном исследователями на протяжении более ста лет. Методом исследования стал комплексный междисциплинарный подход в синхронном и диахронном диапазонах. Ландшафтный код выступает в качестве кормящей и защищающей языческой стихии. Человек был онтологически вписан в реальный и мифоритуальный ландшафт, зависимость от которого и от языческих сил природы ярко проявляется в фольклоре и обрядовых практиках, пролонгированных в историческую современность. Ландшафтный код «земля/тайга» представлен единством родоплеменных промысловых пространств, пронизанных сетью коммуникационных и информационных каналов, нитями традиционных маршрутов с летними временными и зимними стационарными жилищами, следами представителей животного мира, человека, нематериальных объектов. Предлагаются рекомендации по сохранению уникального этноэкологического локуса древних охотников таежной зоны Сибири.

Published: July 2024

Reducing global carbon dioxide emissions is a critical issue that requires sustainable, energy-efficient and scalable solutions. Electrochemical carbon dioxide capture and release with redox active molecule has drawn an intense amount of interest, owing to its mild operation condition, low energy consumption and high flexibility compared with traditional CO2 capture technologies. Here, we demonstrate a series of thiolate/ disulfide redox couples, with high practical solubility and weak protonation ability, which are able to reversibly capture and release CO¬2. The mechanism of CO2 capture and release using such redox couples is elucidated via combining cyclic voltammetric and Fourier transform infrared spectroscopic measurements. Further, we show the redox performance of such materials can be significantly improved by functional group tuning and electrolyte engineering. Among them, the 4-fluorophenyl thiolate/4-fluorophenyl disulfide redox couple shows an initial CO2 capacity utilization efficiency and average release/capture efficiency of ~100% and ~90%, respectively, under simulated flue gas (20% CO2) in a flow system. Besides, it exhibits a good cycling stability against moisture. This work opens new opportunity to future works in developing thiolate/disulfide redox couples for large-scale electrochemical carbon dioxide capture and release applications.
Tetrafluoro(aryl)sulfanylated Bicyclopentane Crystals that Self-Destruct upon Cooling: An Organic "Cryosalient" Material

Published: July 2024

Whereas single crystals of organic compounds that respond to heat ("thermosalient") or light ("photosalient") have been reported and studied in detail, crystalline organic compounds that elicit an extreme mechanical response at cryogenic temperatures ("cryosalient") are relatively rare in the chemical literature. During an attempt to measure an X-ray crystal structure of a tetrafluoro(aryl)sulfanylated bicyclopentane synthesized in our laboratory, we discovered that the crystals jump and forcefully disintegrate upon cooling below ~193 K. Accordingly, we investigated the origin of this cryogenic mechanical response (CMR) through NMR, SC-XRD, DSC, Raman, Brillouin, and microscopy experiments. To our surprise, NMR, SC-XRD, and DSC experiments suggest the phenomenon can neither be attributed to a chemical transformation nor a crystalline-crystalline or crystalline-amorphous phase transition. Rather, microscopy, Raman, and Brillouin experiments provide evidence that the built-up strain released from the crystal upon self-destruction may be associated with a phase transition that occurs in amorphous microstructure within the crystal. This study demonstrates that molecular structural changes within organic material microstructure – which may not necessarily be visible by SC-XRD – can have a significant impact on the thermodynamic behavior of the bulk crystal-line material. Thus, the role of microstructure may be considered more heavily in future mechanistic studies on mechanically responsive crystals.

As aptamer development progresses, their applications have expanded significantly beyond high affinity to include functional capabilities. Currently, identifying functional aptamers relies on traditional SELEX techniques, followed by functional validation and computer-assisted redesign of high-affinity aptamers. However, high affinity does not guarantee optimal functionality, making the search for functional aptamers from binding pools time consuming and labor-intensive. Addressing this challenge, we introduce Functional Aptamers in vitro Evolution (FAIVE), a novel screening method that links sequence functionality to fluorescence intensity. We demonstrated the effectiveness of FAIVE by obtaining modified DNA aptamers capable of disrupting the interaction between SARS-CoV-2 spike receptor-binding domain (RBD) and hACE2, targeting protein-protein interaction inhibition. Furthermore, we investigated the criteria for validating the quality of the bead library generated for selection by modeling the process of emulsion PCR, thus providing theoretical insights for future applications. The concept of incorporating fluorescent signal reporting of aptamer functionality into the aptamer selection process has the potential of facilitate the identification of aptamers with diverse functionalities, and is readily adaptable to various research contexts.

Process optimization in heterogeneous catalysis relies on the control of competing reactions. The reaction mechanisms based on chemical knowledge can be evaluated via density functional theory unveiling experimental catalytic trends. However, this approach finds its limits when applied to complex reaction networks or large molecules, disregarding alternative paths and rare events. Here we present CARE, a foundational model for catalysis on metal surfaces with a rule-based reaction network generator for CxHyOz species built with GAME-Net-UQ, a graph neural network with uncertainty quantification targeting thermodynamic and kinetic parameters, coupled to microkinetic modeling. CARE reproduces experimental activity trends in methanol decomposition, selectivity to C3 products in electrochemical reduction processes, and models the Fischer-Tropsch synthesis to C6 products, including 370k reactions, breaking the current limits of network exploration. This comprehensive model opens the path towards the exploration of thermal and electrocatalytic surface processes previously not amenable to atomistic simulations.

Fluorescent foams with interconnected pores are attractive for the detection and quantification of various products. However, many fluorescent probes are suffering from aggregation-caused fluorescence quenching in their solid/aggregated state, are costly, and/or not straightforward to incorporate in foams, limiting their utility for this application. Herein, non-isocyanate polyurethane foams (NIPUF), prepared by the simple water-induced self-blowing process, present a nonconventional fluorescence behaviour, i.e. they are intrinsically fluorescent with a multicolor emission without requiring ex-situ traditional fluorescent probes. These foams demonstrate utility for capturing-sensing gaseous formaldehyde (an emblematic indoor air pollutant), as well as for detecting and quantifying various metal ions (Fe2+, Cu2+, Fe3+, Hg2+). They are also able to selectively sense tetracycline antibiotic in a ratiometric way with a high sensitivity. By exploiting the unique multicolor photoluminescent foam properties, a smartphone-compatible device is used for the facile antibiotic quantification. This nonconventional fluorescence behaviour is discussed experimentally and theoretically, and is mainly based on clusteroluminescence originating from multiple hydrogen bonding and hetero-atomic sub-luminophores, thus from aggregation-induced emission luminogens that are naturally present in the foams. This work illustrates that easily accessible non-conventional fluorescent NIPU foams characterized by a modular emission wavelength have an enormous potential for multiple substrates detection and, in some cases, their quantification.

Chemical reaction prediction, encompassing forward synthesis and retrosynthesis, stands as a fundamental challenge in organic synthesis. A widely adopted computational approach frames synthesis prediction as a sequence-to-sequence translation task, using the common SMILES representation for molecules. Current evaluation of machine learning methods for retrosynthesis assume perfect training data, overlooking imperfections in reaction equations in popular datasets, such as missing reactants, products, other physical and practical constraints such as temperature and cost, primarily driven by a focus on the target molecule. This limitation leads to an incomplete representation of viable synthetic routes, especially when multiple sets of reactants can yield a given desired product. In response to these shortcomings, this study examines the prevailing evaluation methods and introduces comprehensive metrics designed to address imperfections in the dataset. Our novel metrics not only assess absolute accuracy by comparing predicted outputs with ground truth but also introduce a nuanced evaluation approach. We provide scores for partial correctness and compute adjusted accuracy through graph matching, acknowledging the inherent complexities of retrosynthetic pathways. Additionally, we explore the impact of small molecular augmentations while preserving chemical properties and employ similarity matching to enhance the assessment of prediction quality. We introduce SynFormer, a sequence-to-sequence model tailored for SMILES representation. It incorporates architectural enhancements to the original transformer, effectively tackling the challenges of chemical reaction prediction. SynFormer achieves a top-1 accuracy of 53.2% on the USPTO-50k dataset, demonstrating an improvement over previous state-of-the-art language models while being more efficient and eliminating the need for pre-training.

Purpose: This study examines the relationship between education and fertility in Rwanda. The main objective of this study is to identify the impact of fertility on population growth in Rwanda
Design/Methodology/Approach: This research used the secondary data from the National Institute of Statistics of Rwanda (NISR) reported as the Demographic Health Survey (DHS) dataset spanning 2010, 2015, and 2020 from the National Institute of Statistics of Rwanda(NISR). Utilising stratified random sampling, as implemented in the DHS datasets, provides a robust and representative sample for investigating the impact of growth phases on body weight and morphometrics across different age groups in Rwanda. The Logistic regression model was used to assess the effect of education on fertility in Rwanda.  
Findings: Findings reveal that households with children are significantly more likely to attend school, and non-poor households exhibit higher attendance rates compared to those categorized as poor. Disparities in fertility rates between women with no education and those with higher education underscore the influence of education, with substantial reductions observed over the years. Contraceptive use displays differential patterns across education levels, with higher education correlating with increased usage. Median age of first birth rises with education level, indicating a shift towards later childbirth. The odds ratio (OR) of 0.842, implies that with each unit increase in education attainment, there's a decrease in the odds of experiencing the outcome variable, which presumably pertains to having children. Sex and marital status have minimal influence, with odds ratios of 1.078 and 1.06 respectively. Age shows negligible impact with an odds ratio of 1.01. Conversely, the wealth category strongly predicts having children, with higher-wealth individuals having 3.552 times higher odds.
The Research Limitation: Research is limited by the absence of current DHS dataset
Practical Implication: Understanding these dynamics can inform the development of more effective family planning strategies tailored to specific socio-cultural contexts, ultimately contributing to improved reproductive health outcomes.
Social Implication: Fertility rates exhibit a negative association with education, emphasising the importance of education in demographic transitions
Originality/ value: The unique contribution of this problem lies in its call for a context-specific examination of the relationship between education and fertility in Rwanda, incorporating socio-economic factors, as well as the need for longitudinal studies to capture the long-term effects of educational interventions on fertility behaviours.
