Analysis of Hospital management information systems using cobit 5 framework case study "Saraswati Dental and Oral Hospital in Denpasar”
Authors: Raditya Pramita I Putu Agus , Indrawan Gede , Setemen Komang
Published: March 2024

A hospital's operations, such as patient registration, medical management, financial management, and upgrading the services offered in the hospital, are managed and organized using an application system called a hospital management information system (HMIS). Because the lack of evaluation in the usage of HMIS has led to insufficient security in the HMIS, this research focuses on Saraswati Dental and Oral Hospital as the research site. Due to lax security measures, confidential data is readily accessible. The prevalence of duplicate data entry is an issue, and the success of HMIS performance implementation is still unknown. The COBIT 5 framework has been used to administer the HMIS at Saraswati Dental and Oral Hospital using the MEA (Monitor, Evaluate, Assess) and BAI (Build, Acquire, Implement) domains in response to these problems. This decision was made with the intention of aligning the application with the necessary features, monitoring system security, evaluating, and assessing the domain's alignment with the hospital's strategy in order to ascertain whether the current system still achieves the intended goals and maintains the controls required to satisfy the requirements. This study makes use of questionnaire, observation, and interview techniques. The capacity levels used in the COBIT 5 study were taken from ISO/IEC 15504-2-2003, and they were combined using straightforward mathematical calculations in accordance with the rules for computing capability values. Weaknesses or flaws in the security system that need to be fixed can be found by analyzing the capability levels in the MEA and BAI domains. The study's findings include suggestions for increasing the security system, which will enhance Saraswati Dental and Oral Hospital's HMIS performance and give users and patients with more beneficial outcomes

Published: March 2024

In Senegal, stock recovery and fish classification are based on manual data collection, and the fish caught by the fishery are not often declared. What's more, data collection suffers from a lack of tools for monitoring and counting fish caught at fishing docks. Researchers have carried out studies on the fishery in Senegal, but data collection is almost non-existent. Moreover, there is no local fisheries database or automatic detection and counting algorithm. In this paper, a semantic segmentation algorithm is proposed using intelligent systems for the collection of fishery catches, for the formation of the local database. The data are collected by taking images of fish at the Soumbédioune fishing wharf in Senegal, and are completed with the Fishbase database. They were applied to the algorithm and resulted in a segmented dataset with masks. This constitutes our local database. The database is used with YOLO v8. The latter is very important for detecting images with bounding boxes in order to train the model. The results obtained are very promising for the proposed automatic poison detection and counting model. For example, the recall-confidence scores translate into bounding box performance with scores ranging from 0.01 to 0.75, confirming the performance of this model with bounding boxes
Molecular characters of Pandoraea, a bacterium associated with tomato (Solanum lycopersicum) using 16S rDNA from Limpopo Province, South Africa
Authors: GELDENHUYS GAVIN
Published: March 2024

Tomato is one of the premier vegetables in the world and is widely cultivated for higher yield and economic importance; thus, the area under cultivation is increasing. Pandoraea species can be a risky pathogenic bacterium to tomato plants, impacting the yield. They are gram-negative, motile, and rod-shaped. In 2022, the University of Limpopo conducted a study to identify and name the Pandoraea bacterium found in a tomato field located in Limpopo Province, South Africa. Molecular methods were employed, and the Chelex approach was utilized to extract the 16S rDNA marker, enabling the identification of bacteria present in the soil of tomato fields in South Africa. After conducting tests using specific primers to amplify the 16S rDNA, we have identified the bacterium as Pandoraea. Our analysis indicates that the strain of Pandoraea found in South Africa shares a 90% similarity with a population from Belgium (LR536859). Furthermore, maximum likelihood phylogenetic analysis indicates that this species is grouped with other Pandoraea species, with highly supported (100) bootstrap values. While the 16S rDNA method successfully identified this species, we recommend utilizing other DNA markers for a more comprehensive understanding of the Pandoraea phylogeny.
Improvement of cereal harvest programming methods using computer simulation information technology
Authors: Terentiev Oleksandr M. , Prosyankin Denys I.
Published: March 2024

The paper is dedicated to a topical scientific and applied problem – the development of information technology of computer modelling intended for programming the yield of agricultural crops. The paper describes information technology of computer modelling of the yield of agricultural crops (on the example of Avena sativa subsp. nudisativa), which is based on the application of Bayesian methods to modelling and prediction in conditions of statistical, parametric and structural uncertainty. The study was based on the materials of laboratory experiments carried out in conditions close to natural, on the prediction of physiological processes occurring in plants under the influence of regulated and unregulated factors. Proposed approach described the change in the productivity of grain crops, in particular Avena sativa subsp. nudisativa, depending on the parameters of plant growth and development, photosynthetic apparatus and duration of its functioning. Scientific novelty of the work was application of probabilistic and statistical models in the form of Bayesian networks in the system of programming the yield of agricultural crops. The paper considered several scenarios of the combined effect of growth regulators and herbicides on the productivity of Avena sativa subsp. nudisativa. Net productivity of photosynthesis was chosen as the target variable of the studied process. Mathematical models in the form of Bayesian network turned out to be adequate for the process chosen for modelling. Achieved error of model classification was about 20%. The model structure was built in Genie 2.0 modelling system. It was found that by researching and simulating potential opportunities of ecological features of plants, it was possible to achieve an increase in yield by reducing the doses of herbicides and growth regulators by their combined use, which significantly increased the crop quality. Proposed information technology uses methods of intelligent data analysis, has a modular structure and can be used separately and as part of other information and analytical systems.

Published: March 2024

In the article, in the aspect of engineering and geological safety of structures and communications, the long-term hydrogeological consequences of the support and drainage effects at coastal areas of destroyed Kakhovsky hydro node reservoir as a leading eco-forming component of a giant natural and man-made geosystem are considered. In particular, it included Zaporizhia NPP, the largest in Europe, and the largest irrigation systems in Ukraine. The consequences of the hydrodynamic disaster due to explosion of Kakhovskaya HPP, the dynamics and current state of drainage of the bed of its reservoir are briefly described, according to the data of GIS analysis of space images. And also – the state of hydrogeological and engineering-geological conditions in the reservoir support zone at the time of disaster and in retrospect. A calculated assessment of changes in hydrogeological conditions for the next 10-15 years has been carried out. Long-term natural and man-made threats that arose as a result of such changes in hydrogeological (geofiltration and geodynamic) conditions are named. The set of socio-economic threats that arose due to the negative consequences of Kakhovsky reservoir existence and draining is described. It is emphasized that the restoration of hydrotechnical and water management parameters of the reservoir in the previous values (according to the conservative version) will lead to secondary geospatial water saturation of subsiding loess-loamy silty-clay floatingable rocks that have already undergone deformations due to a decrease in geotechnical stability during the initial flooding and subsequent drainage. This will start a new stage in the formation of dangerous violations of stress-deformed state of coastal slopes, of Zaporizhzhya NPP responsible structures foundation and in nearby cities and towns. A socially and ecologically favorable option for the rehabilitation of affected region is possible only on the modern European ideological and technological basis of taking into account the maximum permissible changes in the hydrological network, i.e. by means of: creating a cascade of low support channel reservoirs with locks and small hydroelectric power stations, reconstruction of riverside ponds and water supply systems, transfer of domestic water supply to underground sources, irrigated lands – for drip irrigation, ecological reclamation and afforestation of drained lands.

Authors: Kosminskyi Ihor , Sankin Ilya , Levchuk Kateryna
Published: March 2024

The possibility of using Stirling engines as energy converting equipment is analyzed. In a global review of energy conversion technologies, it is recognized as an engine with potential for further development. The high efficiency, simplicity and reliability of the Stirling engine design determine the effec-tiveness of its use in various power plants, in particular in cogeneration ones. The most promising develop-ment direction of decentralized heat supply from the point of view of bringing the heat source as close as possible to the consumer is the use of heat pumps. The use of heat pumps allows you to reduce the con-sumption of fuel resources by 10% per year and dispose of waste heat from the environment.

Published: March 2024

The article considers the environmental problems arising from the failure of wastewater infrastructure facilities. Therefore, the purpose of the research is to develop the methodological bases for decision-making during the preparation of organizational and technical procedures for the restoration of the drainage infrastructure in the conditions of the post-war reconstruction of the country on the basis of environmental safety. The methods used during the research: an integrated approach to environmental safety management, methods of system analysis, synthesis, and criterion analysis method. As a result of the research, the consequences caused by the wear and destruction of the drainage infrastructure were analyzed, and the latest studies, devoted to the methods of preparation of organizational and technical procedures for its reconstruction and restoration were analyzed. The substantiation was carried out and the structure of the theoretical and methodological approach to the formation of organizational and technical measures for managing the environmental safety of the functioning of the drainage infrastructure was developed. Systematization of the main factors influencing the results of environmental safety management was carried out. A structural model of the interaction between these factors had been developed. On the basis of the established criteria, a system of indicators had been developed that shows the effectiveness of organizational and technical procedures for managing the environmental safety of the drainage infrastructure. There were developed methodological approaches to making organizational and technical decisions on environmental safety management, ways to increase the efficiency of water drainage infrastructure were shown, and also a flowchart of possible instrumental support of organizational and technical decisions to support environmental safety was developed. As a result, it was established that the management of environmental safety at the current stage requires the development of new methods and organizational and technical solutions, which must be adopted by management subjects in a certain composition. The benefits of this are that the choice of the decision-making algorithm according to the proposed approach and adherence to it, as well as the use of the proposed toolkit, make it possible to ensure the efficient operation of the restored infrastructure on the basis of environmental safety.
Partidos o candidatos-coyunturas; patrones espaciotemporales del voto mexicano 1994-2015
Authors: Gutiérrez-Sánchez Héctor , Ávila-Eggleton Marcela
Published: March 2024

Desde hace algunos años, el modelo Michigan se encuentra en disputa con la teoría de la movilización cognitiva. El primero propone al partido como determinante del voto; la segunda, a la evaluación de candidatos y coyunturas. Se analizaron los resultados electorales 1994-2015, siguiendo ambas posturas teóricas. Se esperaba que los resultados electorales de votos legislativos —donde el partido es casi la única guía para el votante— funcionaran como supone el modelo Michigan y fueran estables en tiempo y espacio. Asimismo, que las elecciones ejecutivas fueran más irregulares, al ser más susceptibles a la movilización cognitiva individualista. Se encontró lo contrario: la presencia de candidatos ejecutivos hace más homogéneos los resultados electorales, lo cual parece sugerir que partido y movilización cognitiva podrían no ser antagónicos, sino, de algún modo, parte de un único mecanismo.
La familia como recurso afectivo y de agencia en el movimiento socio-laboral del Sindicato Mexicano de Electricistas
Authors: Alvarado Gabriela Victoria , Leyva Piña Marco Antonio
Published: March 2024

El Sindicato Mexicano de Electricistas (sme) fue una organización relevante en la historia del movimiento sindical en el país. Sin embargo, el decreto presidencial presentado el 11 de octubre del 2009 tuvo como objetivo la desaparición de una empresa paraestatal denominada Compañía de Luz y Fuerza (clf). Éste dio por terminadas las relaciones laborales con el sme, lo cual consistió en la supresión de la contratación colectiva de los trabajadores, con la finalidad de eliminar a un sindicato apreciable en las luchas sindicales y sociales en el país. Así, la ofensiva estatal en contra del sme fue un movimiento estratégico de privatización de la energía eléctrica, para favorecer a empresarios nacionales e internacionales. En esta investigación tratamos la respuesta de los electricistas que no aceptaron la propuesta gubernamental de un finiquito económico por los años trabajados. Éstos generaron un movimiento de protesta que duró ocho años en defensa de sus fuentes de trabajo. En la subsistencia de este movimiento de electricistas, la familia ha desempeñado un papel fundamental como instancia creadora de recursos afectivos y de toma de decisiones para seguir en la lucha.
Cuidado no remunerado y envejecimiento: un análisis sobre los arreglos domésticos y la reproducción social en Tlaxcala
Authors: Aguilar Pérez Mirza , Toledo González Mónica Patricia
Published: March 2024

En la parte centro y sur de México, específicamente en regiones con un fuerte componente indígena, existe un modelo cultural de organización doméstica que ha sido denominado sistema familiar mesoamericano.1 Entre otras características, este sistema permite la reproducción social de las familias y de las comunidades. Tiene, entre otras representaciones, una figura masculina conocida como el xocoyote. 2 La persistencia del xocoyote en diversas comunidades del altiplano central abre interrogantes sobre el pasado, el presente y el futuro de la organización social del cuidado en México y en particular sobre las desigualdades de género en la atención de las personas en la vejez. Nos interesa reflexionar sobre esta organización tradicional de cuidado no remunerado en dos comunidades de Tlaxcala: San Miguel Contla y San Cosme Xaloztoc. El objetivo de este artículo es analizar la relación entre la feminización/familiarización del cuidado, el envejecimiento poblacional y los usos y costumbres familiares dentro de este sistema familiar en las dos comunidades. Esta investigación es de carácter cualitativo; se realizaron catorce entrevistas y observación directa en dichos lugares.

Representación mediática de la desaparición de mujeres en Puebla, estigmatización y violencia.
Authors: Álvarez Rodríguez Andrea
Published: March 2024

El artículo se propone analizar los sentidos que la prensa digital de nota roja construye alrededor de la desaparición de mujeres en Puebla. Dado que el estudio de la desaparición se enfrenta a las cifras negras y la imprecisión de los datos oficiales, se optó por realizar un estudio hemerográfico basado en un análisis sociológico del contenido, centrado en el análisis e interpretación del texto y los marcos que dan sentido a este discurso. Los resultados muestran que la prensa revisada construye el problema de la desaparición de mujeres a partir de tratamientos inadecuados, basados en estereotipos de género y evaluaciones morales que estigmatizan a las víctimas. El abordaje de la prensa contribuye a la invisibilización de la desaparición y los crímenes asociados a ella, así como a la deshumanización y estereotipación de sus víctimas. Todo esto incide en la forma en que se entiende la desaparición de mujeres, el reconocimiento social de su estatus de víctimas y, en última instancia, en su posibilidad de acceder a la justicia.
Populismo, herencias y política democrática en México. De Luis Echeverría Álvarez a Andrés Manuel López Obrador
Authors: Covarrubias Gonzalez Israel , Gallegos Cruz Cristhian
Published: March 2024

El propósito principal del artículo es analizar el populismo en México a partir de la comparación de tres experiencias de gobierno como son los de Luis Echeverría Álvarez y José López Portillo en los años setenta y el de Andrés Manuel López Obrador en la actualidad. Desde una perspectiva de teoría política, nos interesa mostrar que las herencias políticas juegan un papel fundamental en la aparición de este fenómeno, por lo cual se privilegia el estudio de los usos semánticos del “pueblo” y de la puesta en práctica de la técnica de gobierno del legalismo discriminatorio. Estos dos recursos nos permiten observar empíricamente si las modificaciones promovidas por los líderes populistas en el entramado legal y constitucional producen efectos directos sobre los grupos considerados como el no pueblo, así como en el mantenimiento o la transformación institucional de los regímenes políticos (sean estos autoritarios o democráticos).
Cultura académica disciplinar y procesos de globalización: tendencias y tensiones en las Universidades Públicas Mexicanas
Authors: Anzaldo Álvarez Jaqueline
Published: March 2024

La aproximación al estudio de la cultura académica disciplinar al interior de los Cuerpos Académicos en las Universidades Públicas Estatales mexicanas, constituye un punto de partida para comprender cómo es que se ve alterada por los procesos de globalización, derivado de una política económica tendiente a la privatización y mercantilización de la investigación. Desde una perspectiva institucionalizada, dichos procesos posibilitan que mediante la existencia un nuevo perfil profesional de académico, se logre tanto la incorporación de éste a un mundo competitivo, como el impulso al desarrollo económico y social de su país a través de las actividades que él genera. El objetivo de este trabajo es reflexionar en torno a la relación entre cultura académica disciplinar y procesos de globalización, con la finalidad de establecer cuáles son las tendencias y tensiones que ello genera al interior de los Cuerpos Académicos de las Universidades Públicas Estatales mexicanas. Para ello, se siguió una metodología teórica-descriptiva y un método histórico, en el cual se destacan a los actores e instituciones que son componentes clave para entender tal vínculo. Se concluye que la cultura académica disciplinar al interior de los Cuerpos Académicos dentro de las Universidades Públicas Estatales mexicanas deriva del establecimiento de un modelo económico propenso al desdibujamiento de las fronteras geográficas, sociales, culturales y económicas.

Published: March 2024

Resumen:Aunque el cambio climático es un fenómeno natural en la Tierra, la sociedad actual se enfrenta a un calentamiento global sin precedentes. La modificación del clima planetario, motivado principalmente por actividades humanas, podría tener impactos ecológicos, económicos y sociales. Esta situación plantea la necesidad de discutir el impacto de los factores psicosociales en la conducta proambiental y sostenible de los grupos humanos.Objetivo: Explorar las creencias de las personas de una comunidad universitaria respecto al cambio climático y descubrir si existe una relación entre estas creencias y el comportamiento proambiental.Métodos de investigación: Estudio exploratorio mediante encuesta a una muestra (n=135) de la Universidad de Santiago de Chile y revisión bibliográfica.Resultados: Los resultados demuestran que los encuestados son capaces de comprender cognitivamente los riesgos del calentamiento global, pero muestran baja proporción de comportamiento proambiental. En la revisión bibliográfica, se concluye que las personas adoptan conductas proambientales cuando están suficientemente informadas sobre los temas ambientales, tienen actitudes positivas hacia ellos y se sienten empoderadas para generar cambios cualitativos, efectivos y que no les generen mayores dificultades posteriormente. Originalidad/Valor del artículo: Este artículo proporciona una perspectiva relacional entre las percepciones del cambio climático y el comportamiento proambiental en una muestra universitaria. Basándose en esta relación se hacen propuestas para implementar programas educativos en diversos niveles.Palabras clave: calentamiento global, comportamiento proambiental, sociedad, sustentabilidad
 
Conflicto de interés en el Tribunal Federal de Justicia Administrativa
Authors: Tenorio Mendoza Miguel Angel
Published: March 2024

El objetivo es determinar si existe un conflicto de interés en materia fiscal en el Tribunal Federal de Justicia Administrativa (TFJA). El titular del Poder Ejecutivo de los Estados Unidos Mexicanos es parte demandada en los juicios de nulidad promovidos por los contribuyentes ante dicho tribunal. Los magistrados de ese tribunal son propuestos y elegidos por el presidente de la República, quien funge como parte demandada en los juicios que dichos magistrados deben resolver. Lo anterior con la ratificación del Senado de la República. Ello opaca la relación a la independencia e imparcialidad del tribunal y juzgadores. Se analiza el conflicto de interés potencial conformado por la relación de hecho y de derecho entre el Titular del Poder Ejecutivo Federal, sus subordinadas: la Secretaría de Hacienda y Crédito Público (SHCP), el Servicio de Administración Tributaria (SAT), y los magistrados del Tribunal Federal de Justicia Administrativa. Encontrarse en una situación de conflicto de interés no es algo en sí inmoral, si el que se encuentra involuntariamente en esta situación no es responsable de ello. El modelo de justicia administrativa francés imperante, está evolucionando hacia un modelo judicial en casi la mitad de las entidades federativas.
Obligatoriedad de las sentencias de la Corte Interamericana de Derechos Humanos contra México
Authors: Gallardo Loya Roberto Carlos
Published: March 2024

El presente artículo tiene por objetivo estudiar la obligatoriedad del sistema interamericano de derechos humanos a raíz de la reforma constitucional mexicana de 2011 y la relación de México con la principal fuente de dicho sistema: la Convención Americana sobre Derechos Humanos de 1969, a través de una investigación analítica y documental. Como resultado, se obtiene que México reconoce la obligatoriedad de tal convención, de la jurisprudencia interamericana y del control de convencionalidad, pero lo hace con importantes matices que reducen el impacto del sistema interamericano en el orden jurídico nacional, apoyándose para tal efecto en el artículo 133 constitucional, el cual mandata que todos los tratados internacionales deben estar de acuerdo con la misma. Asimismo, resulta que México se mantiene como un Estado recurrentemente responsable por violar derechos humanos a través de sus actos y normas jurídicas, incluyendo éstas al texto constitucional, como resulta de la lectura de las sentencias emitidas por la Corte Interamericana de Derechos Humanos entre 2011 y 2023.
Exploring volunteerism : understanding motivations, satisfaction, and longevity among Court Appointed Special Advocate volunteers
Authors:   , Brown Michele Allyn
Published: March 2024

Volunteerism is extensively studied in literature, with a specific focus on what motivates individuals to volunteer, what satisfies volunteers, and why individuals choose to volunteer for a prolonged period. Court Appointed Special Advocates, or CASAs, are volunteers that work with and advocate for children involved in the foster care system. This study utilized a mixed methods design to better understand motivations, satisfaction, role identity, relationships, and organizational context among CASA volunteers in one small region. Surveys were administered to 288 active CASA volunteers, with a final sample size of 63 participants. Individual interviews were conducted with four active CASA volunteers. Correlations indicated that all but one of the hypotheses in the study were supported, and regression analysis determined one predictor -- satisfaction predicts motivation among participants in the study. Integration of the data was beneficial to better understanding CASA volunteers, and revealed these participants identified relationships with the children they serve of utmost importance, and identified gaps that exist in training, as well as among relations between CASA volunteers and the child welfare system. The study highlights areas that the agency can focus on to improve recruitment and retention of volunteers as well as additional research areas to continue to explore the phenomenon of CASA volunteerism.
Interplay of Bacillus anthracis spore proteins in the assembly process of the exosporium
Authors:   , Durand Heredia Jorge
Published: March 2024

Spores are the infectious form of the zoonotic pathogen, Bacillus anthracis. The outermost layer of these spores is the exosporium. It consists of a basal layer (major structural proteins are ExsY, CotY, BxpB, and ExsFB) and an outermost nap layer containing, mainly, the BclA glycoprotein. The major structural proteins of the inner basal layer are CotY (at the bottlecap) and ExsY. Outer basal layer proteins, BxpB and ExsFB, are needed for BclA incorporation to the spore surface. We investigated the role of sequence differences between these proteins in localization during exosporium assembly. We found that the sequence differences between CotY and ExsY were less important for their localization than timing of expression of the respective genes. The timing of expression of the bxpB and exsFB genes, and the N-terminal sequences of their protein products, are important for proper assembly into the basal layer. Fluorescent fusion constructs with fluorophore at the C-terminus of CotY or ExsY resulted in good incorporation but the fusion hybrid proteins were not fully functional. BxpB and ExsFB assembly appears not to be completely abolished in mutants lacking ExsY and CotY, despite these spores lacking a visible exosporium. Bacterial two hybrid studies were used to examine interaction strength with full-length and truncated proteins. Interactions were not only observed between ExsY and CotY, but between these two basal layer structural proteins and CotE and CotO. These latter proteins are part of the polypeptide chain that anchors the exosporium to the spore coat during the exosporium assembly process. Using transmission electron and fluorescent microscopy, western blotting, and immunofluorescence we examined the impact of single, double, and triple mutants of basal layer proteins on spore morphology, protein content and distribution. BxpB and to a lesser extent ExsFB can self-assemble in vitro into higher molecular weight forms resistant to heat and reducing conditions. This self-assembly capacity is shared by other exosporium proteins, as others have demonstrated for ExsY and CotY. However, the mechanisms may be different with BxpB and ExsFB as disulfide bonds do not play a significant role in this process.
Three essays on the demand system
Authors:   , Jeon Younghyeon
Published: March 2024

This first essay investigates how scanner data affect demand elasticity estimates and develops methods for scientists to adapt estimated elasticities to analyses of specific policies. We conduct a meta-analysis of U.S. demand elasticities and find evidence that scanner data generate statistically different elasticities, with more elastic demand than other data types. Own-price elasticity estimates from household scanner quantity data appear to be more elastic than other quantity types. Household-level estimates using retail scanner price data, as proxies for prices, tend to be more price-elastic than other price types. These results suggest caution or adjustment when selecting elasticities for policy analysis. The second essay proposes an approach to meta-analysis that is consistent with demand theory. Meta-analyses of demand elasticity do not impose theoretical demand constraints even though elasticities are derived from a demand system. Specifically, we estimate the fundamental parameters elasticity formula of the Quadratic Almost Ideal Demand System using nonlinear least squares augmented by a wild bootstrap procedure for bias correction and to allow for heteroskedasticity across both studies and food categories. Furthermore, using the estimated fundamental parameters and historical market data, we estimate price and income elasticities for the eight major food categories in the United States. The most significant implication of this analysis is that our empirical framework aligns meta-analysis with demand theory, facilitating welfare calculations. Additionally, this method enables the easy computation of demand elasticities using relevant market data. This new approach could become a valuable tool for applied economists. The third essay estimates food demand elasticities across countries using the Exact Affine Stone Index model. The primary objective of this study is to directly estimate a cross-country demand system for aggregated commodities using historical data and produce theoretically consistent demands for applied analysis. We use annual country-level data from the Aglink-Cosimo model data of the OECD-FAO and include 11 regional groups including 45 countries and regions. For the analysis, we extend the EASI model by including the regional group fixed effects and estimate the quartic Engel curve based on the likelihood ratio test result. Finally, using the estimates from the EASI model, we calculate unconditional price and income elasticities by each regional group.
The process of becoming a culturally responsive school leader in high school
Authors:   , Laughlin David
Published: March 2024

Purpose: The purpose of this study was to investigate the process by which culturally responsive school leaders (CRSL) become CRSL in secondary public schools. Although there is a clear need for leaders trained in culturally responsive practices, little is known about high school leaders' journey to become culturally responsive school leaders (CRSL). This study sought to acquire greater detail on the formative experiences and seminal moments that occurred for leaders, which led to the school leaders self- identifying as CRSL. Research Methods: This study utilized a qualitative research methodology through narrative inquiry to answer the research questions. Interviews were conducted to collect participants' narrative stories. Participants met three criteria to be a part of this study: 1) school leader in a public high school, 2) five years of educational experience and 3) an interest in inclusion as it relates to culturally responsive school leadership in their screening questionnaire. High school leaders described the events, people, practices and/or policies that brought them to believe that they are culturally responsive in their school communities. Discussion and Implications: The analysis of the data revealed that personal experience in life and education and equity training were the major factors that led these leaders to become CRSL. This paper provides reflections on these findings and future research needs. This paper also discussed implications for policy and practice based on these findings.

Published: March 2024

Aedes aegypti has been implicated as the vector responsible for transmission of dengue, chikungunya, and Zika viruses during disease outbreaks in Florida within the past 15 years. Recently, locally acquired dengue cases have increased dramatically, with more than 450 cases documented in Florida since 2019. This mosquito is known to be resistant to pyrethroid-based insecticides in Florida. Resistance of insects to pyrethroids due to knockdown resistance (kdr) is the result of single nucleotide polymorphisms (SNPs) in the voltage-gated sodium channel gene (vgsc). Recently, two novel SNPs, F174I and E478K, and four known SNPs, V410L, S723T, D1763Y, and Q1853R were reported circulating in Floridian Ae. aegypti populations for the first time. The present study provides a more comprehensive estimate of these SNP frequencies through the screening of a larger number of Floridian Ae. aegypti samples using a new custom multiplex SNP assay we developed using the Agena Biosciences iPLEX Assay platform to facilitate the rapid screening of multiple SNPs at an affordable cost. Our assay was successful in screening 162 Ae. aegypti mosquitoes for 8 SNPs from 4 counties in Southern Florida (Broward, Collier, Palm Beach, and Monroe Counties). This new assay can be used for studies examining the association between genetic mutations and pyrethroid-resistant phenotypes in Ae. aegypti populations such as increased time of survival after insecticide exposure.
SALINITY EFFECTS ON THE DISTRIBUTION OF AEDES AEGYPTI AND AEDES ALBOPICTUS IN ST. JOHNS COUNTY, FLORIDA
Authors: Aryaprema Vindhya S. , Caride Kassidy , Kuppe Connor , Xue Rui-De , Qualls Whitney A.
Published: March 2024

The distribution of Aedes aegypti in St. Johns County (SJC), Florida is suggested to be coastal along the inter-coastal waterway. Anastasia Mosquito Control District (AMCD) conducted a study to investigate the effects of salinity on the distribution of container- inhabiting Aedes in SJC. Mean weekly abundances of Aedes aegypti and Aedes albopictus at 7 different distances along the coastal-inland gradient, ranging from the SJC coast to the St. Johns River, were monitored for 10 weeks. Bi-weekly salinity measurements of potential Aedes breeding containers were obtained at each distance. A laboratory test was conducted by allowing preferential oviposition at different salinity levels and adult emergence was monitored. Both container salinity and Ae. aegypti abundance were significantly higher up to 5.0 km from the coast compared to the other distances. Ae. aegypti abundance was positively and negatively associated with the container salinity and distance from the coast respectively. Ae. albopictus abundance was significantly different (lower) only at the distance at which the highest salinity was recorded. The association of abundance (positive) was significant only with the distance from the coast. The adult emergence rate of Ae. aegypti in the laboratory was higher at higher salinity levels up to 5 ppt while there was no significant difference in Ae. albopictus emergence rate at different salinities. The study demonstrated a possible salinity effect on the distribution of Ae. aegypti but not Ae. albopictus in SJC, FL. The results warrant further studies on salinity effects with other confounding environmental factors that would contribute to the distribution of the two species in the county.

West Nile virus (WNV) and St. Louis encephalitis virus (SLEV) pose a significant public health threat in the United States. These viruses are known to adapt rapidly to new amplifying hosts and geographic environments, making effective surveillance critical for public health efforts. This study evaluated the effectiveness of traditional reverse transcription polymerase chain reaction (RT-PCR) for surveillance purposes compared to quantitative RT-PCR (RT-qPCR) in detecting WNV and SLEV in mosquito pools. Mosquito pools were collected and screened for WNV and SLEV over a 10-year period. This study found an increase in the number of flavivirus-positive yet WNV-/SLEV-negative mosquito pools during 2018 compared to previous years. Quantitative RT-PCR detected more positive WNV and SLEV pools compared to traditional RT-PCR, eliminating false negatives and identifying false positives. The findings underscore the importance of using RT-qPCR for arboviral surveillance to accurately detect circulating viruses and enable timely public health interventions. Changes in local trends in mosquito-borne viruses and vector populations have the potential to impact public health, emphasizing the need for proactive surveillance measures.

Green marketing is a marketing and product development method from a company oriented towards environmental sustainability. This research further aims to discover if green marketing can influence the increase in revenue and firm value of companies in Asia through the ROA ROE and PER indicators. In its analysis, this research uses a research methodology in the form of quantitative research with a research sample of 30 companies in Asia that implement green marketing with indicators (Green product, green promotion, green price and green place) and then tested using SPSS. The results of this research are 1. Green marketing turns out to have no correlation with increasing company revenue in Asia 2. Green marketing has an influence on firm value. The implications of this research encourage companies in Asia to focus more on green marketing strategies as a way to increase their long-term value, which may be more important than shortterm revenue growth for increasing a company's stability and future growth.

Introduction: Mastication is a complex rhythmical activity that requires coordination of the neuro-musculature to prepare the food for swallowing. Masticatory performance can be influenced by some factors, such as bite force. Underweight and overweight/obese persons had reported having low bite force. The purpose of this study was to compare the masticatory performance between underweight, normal weight, and overweight/obese adults. Methods: In this cross-sectional study, 60 students of Universitas Sriwijaya were included (age: 21-25 years). Subjects were grouped according to their BMI: group I (underweight), group II (normal weight), and group III (overweight/obese). Masticatory performance was evaluated with the sieves method. During the masticatory performance test, subjects were asked to chew 3-gram peanuts for 20 masticatory strokes, which was done three times. Peanut particles that had been chewed were filtered with a sieve. The volume of peanut particles passed through the sieve was divided by the volume of total particles and multiplied by 100 percent, which the result was noted as a masticatory performance score. The One-way ANOVA test was employed to identify differences between groups. P values ≤0.05 were considered statistically significant. Results: The underweight group showed the smallest masticatory performance score, followed by the overweight/obese group, while the normal weight group showed the highest score. There was a significant difference in masticatory performance score between the underweight and normal weight group (p<0,05), while the rest were not showed a significant difference (p>0,05). Conclusion: The underweight and overweight/obesity groups had a lower masticatory performance compared to the normal weight group.

Introduction: Staphylococcus aureus is one of the opportunistic bacteria in the oral cavity that can cause various diseases, including periapical abscesses. Microbial infection treatment must pay attention to selected antibiotics. Traditional medicine was very popular with the community because it had very minimal side effects and the availability that is easy to obtain. Suruhan leaves could be utilized as an antibacterial due to their content of tannins, saponins, flavonoids, and alkaloids, which inhibit bacterial growth. Purpose: This study aimed to determine the effectiveness of the antibacterial extract of suruhan leaves (Peperomia pellucida L) against Staphylococcus aureus. Methods: This study was an in vitro laboratory experimental study. The test group used an extract of suruhan leaf with concentrations of 20%, 40%, and 60% obtained by the soxhlation method. Clindamycin was used as a positive control, and distilled water as a negative control.  The antibacterial potency was tested using the disc diffusion method to determine the value of the inhibition zone, and the dilution method to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). The inhibition zone values were then analyzed statistically using one-way ANOVA and post-hoc Tukey tests. Results: This study revealed that the 60% concentration of extract suruhan leaf had an average inhibition zone of 18.27 mm, but smaller than clindamycin. The MIC test results of extract suruhan leaf were determined at a concentration of 20% and MBC at 40%. Conclusion: Suruhan leaf extract (Peperomia pellucida L.) had antibacterial activity against Staphylococcus aureus.
