Published: June 2023

Objective: To analyze the possibilities and actions required to foster the introduction of technologies consistent with the term “agriculture 4.0” in Mexico.Design/Methodology/Approach: To identify providers of technology in Mexico. To present the cost-benefit equation regarding the adoption of said technology as applied to the cultivation of maize in different regions. Todesign and construct an adoption propensity index that will serve as a basis to propose focused and adequate actions to remove technology access barriers.Results: Mexico has a young and wide offer of technology, both tangible and intangible, where digital platforms of agricultural management, mobile apps, and remote monitoring predominate. The cost-benefit relationshipoffers a large margin to adopt new technologies. However, there are adoption barriers (related to education or infrastructure, for instance) that represent a challenge to different regions of the country: the northern,northeastern, and western states of Mexico are more likely to adopt new technologies.Study limitations/Implications: Further experimental and field analysesare required to delve deeper into potential additional barriers (culture-related, for example).

Findings/Conclusions: The cost-benefit analysis offers a large margin foradoption. However, the propensity to adopt is associated to restrictingfactors such as the producers’ educational level, the production unit’s sizeand level of mechanization, the access to and use of Information andCommunication Technologies, and the telecoms infrastructure, whosegeographic disparity is significant. The public sector’s intervention isdesirable to reduce the gap between the supply and demand oftechnologies, as well as the access barriers to the latter.

Published: June 2023

Objective: The increase in the number of sheep in herds is accompanied many times by bad practices, which lead to nutritional deficiencies, rises in parasitism and loss of homeostasis. Therefore, gastrointestinal parasites from sheep were characterized from four municipalities of the state of Campeche.
Design/methodology/approach: The number of sheep studied was 243, evaluating the body weight, body condition, coloring of the eye mucosae, age, eggs per grams of feces, and family of parasites. The data were analyzed through an ANOVA and Tukey’s means test (P<0.05), as well as Spearman’s correlation analysis using the statistical package Statistica 7.
Results: Five parasite families were found (Trichostrongyloidae, Strongyloidae, Trichuridae, Eimeriidae and Anoplocephalidae). In the production systems of the municipality of Calakmul the five families of parasites were found, with a parasite load of 3,571 hpg. The family Trichostrongyloidae presented the highest frequency in the municipalities of Champotón and Calakmul with 52 and 75%, respectively. The animals with best body condition, FAMACHA© and lowest parasite load were observed in Hecelchakán.
Limitations on study/implications: It is suggested to carry out a study of anthelmintic resistance, to establish a management of prevention and control of gastrointestinal parasites.
Findings/conclusions: The frequency of gastrointestinal parasites is influenced by the management and the municipality of origin within the sheep production systems in the state of Campeche.
Examining the Relationship Between Access to Healthcare and Marginalization in Toronto
Authors: DiMartella-Orsi Julia
Published: June 2023

This study analyzes the association between healthcare accessibility and marginalization using the city of Toronto as a case study. Access to healthcare is determined by the 2020 Statistics Canada Proximity Measures Database, and marginalization is measured using the four dimensions of marginalization in the 2016 Ontario Marginalization Index. Techniques such as choropleth mapping and Univariate global and local Moran’s I were applied, followed by an OLS and Lag-error regression. The results indicated that as material deprivation increased healthcare access decreased, and that as dependency increased access increased – however they were not statistically significant. Conversely, ethnic concentration and residential instability were statistically significant, and increased as accessibility to healthcare increased. Based on these results, it was concluded that greater marginalization led to greater healthcare access in Toronto. These results contradicted one of this study’s working hypotheses and recent research on healthcare accessibility, that find that as marginalization increases healthcare accessibility decreases.
A Social and Spatial Analysis of Firearm Related Incidents in Toronto
Authors: Ramnarayan Miranda
Published: June 2023

The overall objective of this paper is to determine the location of spatio-temporal clustering of Firearm Related Incidents (FRI) in the City of Toronto between 2014-2018, to determine specific demographic, economic and social variables that would most likely be impacted by FRI violence and explore potential locations to host support groups for populations disproportionally impacted by FRI. Utilizing PCA/factor analysis and a grouping analysis (K-Means) was done as an attempt to minimize the presence of ecological fallacy and reduce the impact of spatial stigma typically associated to subgroups of the population historically impacted by FRI. A regression model was done to test the validity of the grouping analysis and finally a location-allocation model was produced to identify potential support centre locations. Findings revealed that FRI in Toronto rose between 2014-2017 but decreased in 2018. There is spatial auto-correlation occurring throughout all years and areas historically impacted see a rise in FRI as years progress. Findings also revealed that variables for low educational attainment, low income, high visible minority status, lone parents and those between the ages of 0-19 were more likely to encounter FRI. A total of 21 potential locations were identified in a way to alleviate the side effects of FRI occurring in identified areas.

Development and Evaluation of an Open-Source Network Distance Tool for QGIS: A Huff Model Case Study
Authors: Johnson Luke
Published: June 2023

The Huff Model allows researchers to model retail catchment areas using the distance from consumers to stores. To represent the real world as closely as possible, network distance should be used as an input for the Huff Model, but existing tools are either expensive or very slow. The goal of this research is to develop a new, open-source tool to calculate network distance and illustrate the tool’s role as an input to the Huff model on a case study examining major grocery store catchment areas in the City of Toronto. The new tool was developed in Python as a script to be executed in QGIS. To improve upon existing tools, the Python library igraph was utilized, which helped decrease the run time of calculations compared to an existing tool by a factor of 268, while maintaining accuracy of the output. The case study found that some catchment areas for Metro grocery stores are very large and there might be an opportunity for a competitor to move in to capitalize on an underserved market.
Predicting Sensitive Information Leakage in IoT Applications Using Flows-Aware Machine Learning Approach
Authors: Naeem Hajra
Published: June 2023

This thesis presents techniques for identiﬁcation of vulnerable IoT applications. The techniques focus on a category of vulnerabilities that leads to sensitive information leakage which can be identiﬁed by using taint ﬂow analysis. We analyze the source code of applications to recover tokens along their frequencies. We have developed a tool called Token2Vec, which transforms the source code tokens into vectors. If these tokens have a sink, we search for tainted ﬂows. The tainted ﬂows search is implemented as a tool called FlowsMiner. The tool takes far less time than static analysis counterparts. Our tool called Flow2Vec transforms the tainted ﬂows into vectors. The machine learning algorithms are used to build models. The experiments show that the proposed approach has improved the accuracy of the prediction models for all algorithms and the best case for Corpus1 dataset is improved from 87.88% to 93.94% and for Corpus2 from 66.29% to 92.7%.
Precision Phosphene Control Through Cutaneous Facial Electrical Stimulation
Authors: Sadrzadeh-Afsharazar Faraz
Published: June 2023

The application of weak pulsating electrical currents across the facial skin produces visual experiences called phosphenes. Through the precise control of the visuo-spatial orientation of phosphenes, information can be directly sent into the visual field as a means of visual guidance for the partially-blind. In a human trial (8 healthy individuals), the participants were asked to draw their visual percepts, while having eight select regions of their face electrically stimulated. The phosphene drawings were evaluated using various metrics such as sensitivity, specificity, and mass centroid. Out of the eight proposed stimulation sites, four stimulation sites (templar, left transorbital, left infraorbital, and transnasal configurations) produced the most reproducible phosphenes, with average sensitivity and specificity scores of 68.8% and 96.1% respectively. To the best of our knowledge, this was the first time that spatially resolved phosphenes were stimulated through cutaneous electrical stimulation, without any surgical intervention.

Exploring Yersinia ruckeri (O1 Biotype 2) infection in three early life-stages of rainbow trout
Authors: Waine A , Katsiadaki I , Sebire M , Tidbury H
Published: June 2023

Enteric redmouth disease (ERM) caused by the enterobacterium Yersinia ruckeri poses a significant threat to salmonid aquaculture globally. Despite decades of experimental infection studies, key knowledge gaps remain regarding the onset of disease susceptibility and mechanisms of immunity during early developmental stages, undermining disease management efforts in all susceptible life-stages. In this study, a series of immersion challenges were conducted, challenging and re-challenging rainbow trout Oncorhynchus mykiss (Walbaum) at 7, 14 and 51 d post-hatch (dph; mean weights = 0.085, 0.1 and 2.0 g respectively) to high concentrations (1.72 × 107-1.1 × 108 CFU) of Y. ruckeri at 15°C. This study indicates the hitherto unknown initial point of susceptibility to infection as the time of first ingestion of exogenous food (14 dph), and shows that individuals surviving primary challenge at 14 dph are significantly more likely to survive re-challenge at 51 dph compared with naive individuals (hazard ratio = 1.446, p = 0.032). Other key findings include large variation in mortality between different development-stages, from 21.1% at 14 dph to 81.2% at 51 dph, and novel age-dependent symptoms not reported previously. Results from this study enhance our understanding of ERM in juvenile rainbow trout and inform the development of improved aquatic animal health management strategies, thereby contributing to the productivity and sustainability of salmonid aquaculture into the future.
Estimación de la mortalidad por COVID-19 en Cartagena, Colombia al inicio de la pandemia, año 2020, utilizando el método captura – recaptura
Authors: Osorio Merchán May Bibiana , Heredia Melo Damaris
Published: June 2023

Introducción: la revisión de la variación en la mortalidad de una población permite identificar el posible impacto de una nueva enfermedad infecciosa, por lo que es deseable conocer con la mayor rapidez, las muertes que puedan estar atribuidas a un determinado agente infeccioso como es el SARS-CoV2. La revisión de varias fuentes de información permite comparar, detectar posibles subregistros y estimar una mortalidad aproximada a la realidad, para la toma de decisiones oportunas. En el mes de mayo de 2020 el INS brindó asistencia técnica en el Distrito Especial y Cultural de Cartagena con el objetivo establecer el subregistro de mortalidad por COVID-19, utilizando el método de captura – recaptura, con el fin de proporcionar información rápida sobre la introducción y avance de la pandemia. Metodología: estudio descriptivo, utilizando el método de captura recaptura para la estimación de las mortalidades por COVID-19. Las fuentes de información fueron los registros administrativos de RUAF y las licencias de inhumación. Resultados: se identificaron 254 defunciones por COVID-19, desde el 1 de marzo al 18 de mayo de 2020 en el registro de RUAF-ND y 203 defunciones en el registro de licencias de inhumaciones y cremaciones. Con la comparación de las dos fuentes se estimaron un total de 307 muertes para ese periodo. La estimación de la tasa de mortalidad utilizando el método de captura – recaptura fue de 29,3; con RUAF fue de 24,3 y con las licencias de defunción de 19,4. El porcentaje de subregistro fue de 17,2 % con relación a RUAF-ND. Conclusiones: el análisis conjunto de las fuentes de RUAF-ND y Licencias de inhumación y el uso de la metodología de captura-recaptura permitió tener una aproximación más real del comportamiento de las muertes por COVID-19 en el distrito de Cartagena en el momento de introducción del virus al territorio, lo que aportó a la caracterización oportuna de la magnitud del evento y el establecimiento de medidas de control específicas
Análisis espacial del comportamiento del intento de suicidio de casos notificados en Cali y Medellín, Colombia, 2021
Authors: Rojas Hernández Juan Camilo , Chaves Guerrero Julián Felipe , Mosquera Bahamón Yalena , Borbón Ramos Milena Edith
Published: June 2023

Introducción: el intento de suicidio es una conducta potencialmente lesiva, autoinfligida, con la intencionalidad de provocarse la muerte, realizada por un individuo por medio de varios métodos y sin resultado fatal. Entre los factores desencadenantes están la pérdida reciente de un ser querido y bajos ingresos económicos. El objetivo es realizar un análisis espacial para identificar la posible relación entre casos de intento de suicidio, Índice de Pobreza Multidimensional (IPM) y COVID-19, así como determinar las incidencias según IPM durante 2021. Metodología: análisis retrospectivo y espacial de casos de intento de suicidio notificados por Cali y Medellín al Sistema Nacional de Vigilancia en Salud Pública (Sivigila) durante 2021; se revisaron los casos por características de persona, municipio, dirección y fechas de interés. Se realizó geocodificación de la residencia con ArcGIS, Google Maps y OpenStreetMap; se utilizó el sistema de coordenadas WGS-84. Se generaron mapas de puntos con ubicación de casos, mapas de calor por periodos epidemiológicos y superposición con capas de IPM del Departamento Administrativo Nacional de Estadística - DANE y de casos de COVID-19 del GeoVisor Sivigila en el software QGIS 3.16. Resultados: se identificaron áreas con concentración de casos para las dos ciudades, en zonas principalmente con IPM por encima del 30 %. No se encontró una relación entre las incidencias ajustadas por IPM; sin embargo, se identificó una posible concordancia temporal entre los picos de COVID-19 con una tendencia al aumento en casos de intento de suicidio para los siguientes periodos epidemiológicos. Discusión: el comportamiento de casos presenta un predomino espacial en áreas con IPM >30 %, al igual que los casos y fallecidos por COVID-19 puede explicar la distribución tipo clúster. Al analizar las incidencias ajustadas por IPM no se encontró una asociación clara, mostrando una posible relación entre la incidencia de casos y la densidad de población de los territorios. Se recomienda implementar este tipo de análisis en otros territorios, revisar factores desencadenantes y de riesgo que puedan estar afectando a la población, con el fin de conocer mejor el comportamiento de esta conducta, identificar áreas de riesgo y orientar esfuerzos en prevención en el país.

Marine mammals of the United States Exploring Expedition, 1838–1842: history and taxonomy
Authors: Jefferson Thomas A.
Published: June 2023

The United States Exploring Expedition of 1838–1842, in some ways, represents the beginning of American marine mammal biology. The expedition returned home with information on at least twelve marine mammal specimens (mostly small cetaceans or pinnipeds), seven of which were considered new species at the time. Commanded by Lieutenant Charles Wilkes, the expedition covered over 80,000 miles, surveyed new waters and lands, and brought back thousands of scientific specimens. Official publications of the expedition by Titian Peale and John Cassin cover the birds and mammals collected. The squadron’s publications, and the journals of its officers and scientists also contain a good deal of information about sightings of marine mammals. Of particular interest were whaling operations and grounds, and the expedition did much to help expand the whaling prospects of the United States around the globe, with a focus on the South Pacific islands. Though largely forgotten today, the “U. S. Ex. Ex.” played an important early role in establishing American influence in marine mammal biology and global whaling operations.

Este artigo apresenta os resultados de uma pesquisa bibliográfica, denominada "estado da arte" realizada nos artigos produzidos pelos professores de Biologia do Programa de Desenvolvimento Educacional do Paraná (PDE) nos anos de 2013-2014 e disponí­veis no portal da Secretaria de Educação do Estado. O objetivo da pesquisa foi analisar, dentre os artigos publicados, aqueles que contemplavam as TIC (Tecnologias da Informação e Comunicação) no ensino-aprendizagem da Biologia e como as Teorias da Aprendizagem (TA) embasaram a utilização/mediação das tecnologias. Como resultados verificou-se que ainda as TIC são utilizadas em sala de aula como ferramentas e não como mediadoras. Além disso, a maioria das propostas de intervenção desenvolvidas pelos professores PDE não apresentam um embasamento adequado das TA que deveriam fundamentá-las. Por outro lado, as propostas que envolvem TIC fundamentadas em TA cognitivistas ou humanistas demonstram resultados bem satisfatórios. Assim, diante dos dados de pesquisa encontrados, foram elaboradas algumas sugestões que amenizem as dificuldades encontradas pelos professores, para que as propostas com TIC possam contribuir com uma formação plena dos sujeitos da educação básica.
Uma análise da natureza epistemológica das atividades experimentais
Authors: Zanatta Shalimar Calegari , Leiria Talisson Fernando
Published: June 2023

Acredita-se, entre os professores de Ciências, de que as atividades experimentais são recursos metodológicos eficientes para o processo de ensino e aprendizagem, por isso, esse tema merece ser abordado em todos os debates estabelecidos nesta área. Conforme a literatura pertinente, as metodologias empregadas para a execução das atividades experimentais no Ensino de Fí­sica se dividem em antes e depois do Physical Science Study Commitee, uma vez que foi a partir deste que elas deixaram de ser demonstrativas e executadas pelos professores, para serem realizadas pelos estudantes, que seguiam um manual de instruções. A execução de atividades experimentais não se mostrou suficiente para promover uma aprendizagem significativa, fato que indica a necessidade de que se promovam mais estudos acerca das metodologias empregadas para este fim. Inserido nesse contexto, este trabalho é parte integrante de uma pesquisa bibliográfica, fundamentada em artigos cientí­ficos de três revistas indexadas, Caderno Brasileiro de Ensino de Fí­sica, Revista Brasileira de Ensino de Fí­sica, e A Fí­sica na Escola, que foram selecionadas por abordarem atividades experimentais na área da Fí­sica, estabelecendo discussões inerentes ao tema. Os 47 artigos encontrados, de acordo com as condições determinadas, foram categorizados utilizando a "Análise de Conteúdo de Bardin" , que contribuiu para a análise dos fundamentos epistemológicos e metodológicos que embasam nosso objeto de pesquisa. Como resultado, as atividades experimentais foram classificadas como executáveis (atividades experimentais que devem ser executadas pelo aluno) ou demonstrativas (atividades experimentais demonstradas pelo professor), nas subcategorias de reprodução ou inovação, qualitativa ou quantitativa. A maioria dos artigos investigados (21,3%) estão categorizados como demonstrativos e de reprodução qualitativa, sendo que, por outro lado, apenas 4,2% deles foram classificados como executáveis e de reprodução qualitativa. Estes resultados indicam que ocorre a maior valorização dos conceitos, em detrimento dos valores quantitativos, com a visão empirista-indutivista da Ciência ainda sendo verificada na maioria deles.
Cidade, modernidade e imaginação: as metrópoles do século XXI na imprensa ilustrada carioca e bonaerense do século XX
Authors: Araujo Viviane da Silva
Published: June 2023

A percepção de que a chegada do século XX inaugurava um novo tempo, anunciando um futuro de progressos materiais, cosmopolitismo e civilização, marcou diversas representações verbais e visuais que ao seu modo produziam sentidos sobre as transformações vividas em diversas cidades latino-americanas. Considerando algumas importantes mudanças ocorridas neste perí­odo – tais como o avanço das técnicas de reprodução de imagens na imprensa; bem como a ascensão de uma perspectiva histórica retrospectiva e prospectiva motivada pelas comemorações pelos centenários de "descoberta" e de independências na América Latina, assim como as transformações no campo da história da arte, como o advento do futurismo – este artigo analisa uma série de crônicas, desenhos e fotomontagens veiculadas na imprensa ilustrada no Rio de Janeiro e em Buenos Aires que produziram imagens futuristas, imaginando textual e visualmente aspectos da paisagem e costumes dessas futuras metrópoles no século XXI.

Authors: Batista Michel Corci , Fusinato Polonia Altoé , Oliveira Aline Alves de
Published: June 2023

Este artigo tem por objetivo investigar os conteúdos de astronomia apresentados nos livros didáticos de ciências do ensino fundamental I, bem como a forma como são abordados no ensino fundamental I. Nesse trabalho a forma como abordamos os dados foi descrita pela Pesquisa Qualitativa, do tipo descritiva. Realizamos uma análise dos conceitos referentes à astronomia, nas vinte e três coleções destinadas ao ensino de ciências para os anos iniciais do ensino fundamental. Essas coleções foram avaliados pelo Programa Nacional do Livro Didático (PNLD 2013). Nossos resultados indicam que de forma geral todas as coleções abordam alguns temas de astronomia, no entanto, não existe um padrão de conteúdos trabalhado e nem dos anos em que um mesmo conteúdo é trabalhado. Podemos ressaltar ainda que os livros didáticos vem melhorando sua estrutura, a cada avaliação, mas que alguns erros apontados em avaliações anteriores ainda persistem, como é o caso de imagens totalmente fora de escala.

Introduction

Sperm interacts with the female reproductive tract and oocyte through proteins, and these cell-to-cell interactions may play a role in sperm fertility. For consideration of a protein as a potential marker of fertility, there must be variability expressed among animals. The proteins dystroglycan (DAG1) and plasma serine protease inhibitor (SERPINA5) have been reported to play a role in cell-to-cell interactions. Thus, the objectives of this study were to characterize the localization and abundance variability of DAG1 and SERPINA5 in bovine sperm, and to investigate the relationship of DAG1 and SERPINA5 with field fertility (i.e., sire conception rate; SCR), in vitro embryo production (IVP), and sperm parameters.

Material and methods

Dairy bulls (n = 22) were classified as high-SCR (SCR > 1.0) or low-SCR (SCR < –4.0), and good [blastocyst (BL)-by-cleavage (CL) ratio (BL/CL) > 39%] or poor (BL/CL < 38%) BL/CL. Sperm was evaluated for DAG1 and SERPINA5 immunolocalization, and concentration in two separate ejaculates. Variance between bulls compared with within bulls was evaluated using a generalized linear model (GLM) procedure. The relationship of SCR and IVP classification on DAG1 and SERPINA5 concentrations, percentage of tail labeled for SERPINA5, SCR, sperm total and progressive motility, sperm plasma membrane integrity (PMI), CL, BL, and BL/CL were evaluated with the GLIMMIX procedure, and the correlations between these variables were evaluated.

Results

Both proteins were localized on the sperm head; however, SERPINA5 was also localized on the sperm tail. There was greater variance in concentration among bulls than within bulls for DAG1 (P < 0.0001; 69.4 vs. 49.1, respectively) and SERPINA5 (P < 0.0001; 325.8 vs. 285.4, respectively). There was a positive correlation between the concentrations of DAG1 and of SERPINA5 (P = 0.01; r = 0.54). In addition, the percentage of tail labeled for SERPINA5 was correlated with PMI (P = 0.05; r = 0.44). There was no relationship between SCR and IVP classifications and DAG1 (P ≥ 0.55), SERPINA5 (P ≥ 0.54), or the percentage of sperm tail labeled for SERPINA5 (P ≥ 0.22).

Discussion

In conclusion, DAG1 and SERPINA5 were localized to the sperm head, and SERPINA 5 was also localized to the tail. Concentrations of DAG1 and SERPINA5 on the sperm head were correlated with each other. The percentage of tail labeled for SERPINA5 was correlated with sperm PMI; however, neither protein was associated with SCR or IVP. Thus, when evaluated by immunofluorescent microscopy, DAG1 and SERPINA5 concentrations are variable and are not good fertility markers for bull sperm.

Published: June 2023

The civil construction industry has a significant role in the socioeconomic development of a country and seeks to understand the emerging technologies of computational resources, such as artificial intelligence, and those that are inserted into the design processes, which influence the construction quality. This work investigates generative design, an approach to projects aided by algorithms. Recent new breakthroughs related to generative design have the potential to drastically change the methods of construction. This article provides a new view of building construction. Thus, through exploratory research based on application examples and a case study, this study presents the innovative aspects of generative design for construction projects.
Unraveling the genomic reorganization of polygalacturonase-inhibiting proteins in chickpea

Published: June 2023

Polygalacturonase-inhibiting proteins (PGIPs) are cell wall proteins that inhibit pathogen polygalacturonases (PGs). PGIPs, like other defense-related proteins, contain extracellular leucine-rich repeats (eLRRs), which are required for pathogen PG recognition. The importance of these PGIPs in plant defense has been well documented. This study focuses on chickpea (Cicer arietinum) PGIPs (CaPGIPs) owing to the limited information available on this important crop. This study identified two novel CaPGIPs (CaPGIP3 and CaPGIP4) and computationally characterized all four CaPGIPs in the gene family, including the previously reported CaPGIP1 and CaPGIP2. The findings suggest that CaPGIP1, CaPGIP3, and CaPGIP4 proteins possess N-terminal signal peptides, ten LRRs, theoretical molecular mass, and isoelectric points comparable to other legume PGIPs. Phylogenetic analysis and multiple sequence alignment revealed that the CaPGIP1, CaPGIP3, and CaPGIP4 amino acid sequences are similar to the other PGIPs reported in legumes. In addition, several cis-acting elements that are typical of pathogen response, tissue-specific activity, hormone response, and abiotic stress-related are present in the promoters of CaPGIP1, CaPGIP3, and CaPGIP4 genes. Localization experiments showed that CaPGIP1, CaPGIP3, and CaPGIP4 are located in the cell wall or membrane. Transcript levels of CaPGIP1, CaPGIP3, and CaPGIP4 genes analyzed at untreated conditions show varied expression patterns analogous to other defense-related gene families. Interestingly, CaPGIP2 lacked a signal peptide, more than half of the LRRs, and other characteristics of a typical PGIP and subcellular localization indicated it is not located in the cell wall or membrane. The study’s findings demonstrate CaPGIP1, CaPGIP3, and CaPGIP4’s similarity to other legume PGIPs and suggest they might possess the potential to combat chickpea pathogens.
