Análisis Organizacional y Financiero del uso de Prácticas Sustentables en Empresas Industriales Hidalguenses

El propósito de la presente investigación, se orienta en conocer si las prácticas sustentables (ahorro de energía eléctrica), realizadas en una muestra de 10 empresas industriales pertenecientes a dos municipios del Estado de Hidalgo, México, influyen en sus estructuras financieras. Para alcanzar los objetivos planteados se calculan dos índices, uno relativo al desarrollo de prácticas sustentables (IPS) y otro, relativo al aspecto financiero (IFIN), ambos similares al propuesto por (Céspedes, (2001); Carrillo, (2014); Vázquez et al., (2011). Losresultados de la aplicación del modelo de regresión lineal, muestran una relación estadísticamente significativa de tipo positivo entre el Índice Financiero (IFIN) y las variables relativas al grado de escolaridad del responsable, número de trabajadores, el (IPS). En definitiva, los resultados nos podrían permitir inferir, en que las empresas que implementan prácticas sustentables, impactan sustancialmente sus estructuras financieras. This paper focuses on ascertaining if the sustainable practices (saving of electrical energy), carried out in a sample of 10 industrial companies belonging to two municipalities of the State of Hidalgo, Mexico, have a significant influence on their financial structures. To achieve the proposed objectives, two indices were calculated, one related to the development of sustainable practices (IPS) and the other related to the financial aspect (IFIN). Both were similar to the one proposed by Céspedes (2001), Carrillo (2014), and Vázquez et al. (2011). The results of the application of the linear regression model show a statistically significant positive relationship between the Financial Index (IFIN) and the variables related to the level of education of the person responsible, number of workers, and the IPS. The results show that companies that implement sustainable practices have a substantial impact on their financial structures

Influencia Del Comité De Auditoría En El Desempeño Financiero Organizacional, En Empresas Mexicanas Cotizadas (2010-2014)

The purpose of this paper is to know the level of compliance with corporate practices related to the audit function, contained in the Code of Best Corporate Practices, issued by the National Banking and Securities Commission and influence on organizational financial performance (specifically on financial profitability), for this, a sample of 405 questionnaires of best corporate practices, belonging to 125 non-financial companies, are listed on the Mexican Stock Exchange during the period, 2010-2014. The results of the application of the linear regression model, could allow us to affirm that the Audit Function (INDEX_FA), increases the financial profitability of the organizations, which is a great success on the part of the Mexican regulators

Micobiota de plantas donadoras y hongos filamentosos contaminantes del establecimiento in vitro de cinco especies forestales

Although protocols to propagate large numbers of woody species by in vitro culture have been developed, microbial contamination of explants is a fundamental problem which limits its application. The objectives of this study were: to identify the donor plant mycobiota and to identify filamentous fungi contaminants at the establishment phase of mahogany, teak, majagua, pine and cedar. Explants of donor plants were placed in moist chamber and were prepared to direct optical microscope of fungal growth. Cultural characteristics and morphological were taken into account to identify filamentous fungi contaminants in the establishment phase. Frequency of all genera identified was determined. Eleven genera of filamentous fungi in donor plants and twenty genera in the establishment of forest species were identified. The genera Botryodiplodia, Cephalosporium, Diplodia, Dreschlera, Geotrichum, Gloeosporium Helminthosporium, Memnoniella, Oidiodendron and Rhinoclediella appeared only during establishment phase. Others such as Alternaria, Aspergillus, Cercospora, Curvularia, Cladosporium, Colletotricum, Fusarium, Nigrospora, Penicillium and Pestalotia were detected in donor plants and during establishment phase. This indicates that the possible source of contamination was the initial explant. The most frequent genera were Botryodiplodia in teak, Nigrospora in majagua and Alternaria in pine, cedar and mahogany. A phytosanitary plan of defence for donor plants was developed. The plan included systemic and contact fungicides whose spectrum of activity covered the identified genera of fungi.Keywords: cedar, mahogany, majagua, micropropagation, microbial contamination, pine, teakA pesar de que se han desarrollado protocolos para propagar un gran número de especies forestales por cultivo in vitro, la contaminación fúngica de los explantes constituye uno de los problemas fundamentales que limita su aplicación. Los objetivos de este trabajo fueron identificar la micobiota de plantas donadoras y los hongos filamentosos contaminantes del establecimiento in vitro de explantes de cinco especies forestales (caoba, teca, majagua, pino y cedro). De plantas donadoras se tomaron explantes que se colocaron en cámara húmeda. Se realizaron preparaciones directas al microscopio óptico del crecimiento fúngico, se aislaron e identificaron los géneros presentes. Además, se aislaron e identificaron los hongos filamentosos contaminantes de la fase de establecimiento. Se identificaron 11 géneros fúngicos presentes en las plantas donadoras y 20 como contaminantes del establecimiento in vitro. Botryodiplodia, Cephalosporium, Diplodia, Dreschlera, Geotrichum, Gloeosporium Helminthosporium, Memnoniella, Oidiodendron y Rhinoclediella aparecieron solamente durante la fase de establecimiento, mientras que Alternaria, Aspergillus, Cercospora, Curvularia, Cladosporium, Colletotricum, Fusarium, Nigrospora, Penicillium y Pestalotia se detectaron en plantas donadoras y durante la fase de establecimiento, lo que indicó que el explante inicial fue la posible fuente de contaminación. Los géneros más frecuentes fueron Botryodiplodia en teca, Nigrospora en majagua y Alternaria en pino, cedro y caoba. A partir de estos resultados se elaboró un plan de defensa fitosanitario para plantas donadoras que incluyó fungicidas sistémicos y de contacto cuyo espectro de acción cubría los géneros de hongos identificados.Palabras clave: caoba, cedro, contaminación microbiana, majagua, micropropagación, pino, tec

Psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT) across cross-cultural subgroups, genders, and sexual orientations: Findings from the International Sex Survey (ISS)

© 2023 The Authors. Published by Elsevier Inc. This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/bync-nd/4.0/).INTRODUCTION: Despite being a widely used screening questionnaire, there is no consensus on the most appropriate measurement model for the Alcohol Use Disorders Identification Test (AUDIT). Furthermore, there have been limited studies on its measurement invariance across cross-cultural subgroups, genders, and sexual orientations. AIMS: The present study aimed to examine the fit of different measurement models for the AUDIT and its measurement invariance across a wide range of subgroups by country, language, gender, and sexual orientation. METHODS: Responses concerning past-year alcohol use from the participants of the cross-sectional International Sex Survey were considered (N = 62,943; M age: 32.73; SD = 12.59). Confirmatory factor analysis, as well as measurement invariance tests were performed for 21 countries, 14 languages, three genders, and four sexual-orientation subgroups that met the minimum sample size requirement for inclusion in these analyses. RESULTS: A two-factor model with factors describing 'alcohol use' (items 1-3) and 'alcohol problems' (items 4-10) showed the best model fit across countries, languages, genders, and sexual orientations. For the former two, scalar and latent mean levels of invariance were reached considering different criteria. For gender and sexual orientation, a latent mean level of invariance was reached. CONCLUSIONS: In line with the two-factor model, the calculation of separate alcohol-use and alcohol-problem scores is recommended when using the AUDIT. The high levels of measurement invariance achieved for the AUDIT support its use in cross-cultural research, capable also of meaningful comparisons among genders and sexual orientations.Peer reviewe

Childhood acute leukemias are frequent in Mexico City: descriptive epidemiology

<p>Abstract</p> <p>Background</p> <p>Worldwide, acute leukemia is the most common type of childhood cancer. It is particularly common in the Hispanic populations residing in the United States, Costa Rica, and Mexico City. The objective of this study was to determine the incidence of acute leukemia in children who were diagnosed and treated in public hospitals in Mexico City.</p> <p>Methods</p> <p>Included in this study were those children, under 15 years of age and residents of Mexico City, who were diagnosed in 2006 and 2007 with leukemia, as determined by using the International Classification of Childhood Cancer. The average annual incidence rates (AAIR), and the standardized average annual incidence rates (SAAIR) per million children were calculated. We calculated crude, age- and sex-specific incidence rates and adjusted for age by the direct method with the world population as standard. We determined if there were a correlation between the incidence of acute leukemias in the various boroughs of Mexico City and either the number of agricultural hectares, the average number of persons per household, or the municipal human development index for Mexico (used as a reference of socio-economic level).</p> <p>Results</p> <p>Although a total of 610 new cases of leukemia were registered during 2006-2007, only 228 fit the criteria for inclusion in this study. The overall SAAIR was 57.6 per million children (95% CI, 46.9-68.3); acute lymphoblastic leukemia (ALL) was the most frequent type of leukemia, constituting 85.1% of the cases (SAAIR: 49.5 per million), followed by acute myeloblastic leukemia at 12.3% (SAAIR: 6.9 per million), and chronic myeloid leukemia at 1.7% (SAAIR: 0.9 per million). The 1-4 years age group had the highest SAAIR for ALL (77.7 per million). For cases of ALL, 73.2% had precursor B-cell immunophenotype (SAAIR: 35.8 per million) and 12.4% had T-cell immunophenotype (SAAIR 6.3 per million). The peak ages for ALL were 2-6 years and 8-10 years. More than half the children (58.8%) were classified as high risk. There was a positive correlation between the average number of persons per household and the incidence of the pre-B immunophenotype (Pearson's r, 0.789; P = 0.02).</p> <p>Conclusions</p> <p>The frequency of ALL in Mexico City is among the highest in the world, similar to those found for Hispanics in the United States and in Costa Rica.</p

The short version of the Sexual Distress Scale (SDS-3): Measurement invariance across countries, gender identities, and sexual orientations

This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial 4.0 International License (CC BY-NC), https://creativecommons.org/licenses/by-nc/4.0/Background The three-item Sexual Distress Scale (SDS-3) has been frequently used to assess distress related to sexuality in public health surveys and research on sexual wellbeing. However, its psychometric properties and measurement invariance across cultural, gender and sexual subgroups have not yet been examined. This multinational study aimed to validate the SDS-3 and test its psychometric properties, including measurement invariance across language, country, gender identity, and sexual orientation groups. Methods We used global survey data from 82,243 individuals (Mean age=32.39 years; 40.3 % men, 57.0 % women, 2.8 % non-binary, and 0.6 % other genders) participating in the International Sexual Survey (ISS; https://internationalsexsurvey.org/) across 42 countries and 26 languages. Participants completed the SDS-3, as well as questions regarding sociodemographic characteristics, including gender identity and sexual orientation. Results Confirmatory factor analysis (CFA) supported a unidimensional factor structure for the SDS-3, and multi-group CFA (MGCFA) suggested that this factor structure was invariant across countries, languages, gender identities, and sexual orientations. Cronbach's α for the unidimensional score was 0.83 (range between 0.76 and 0.89), and McDonald's ω was 0.84 (range between 0.76 and 0.90). Participants who did not experience sexual problems had significantly lower SDS-3 total scores (M = 2.99; SD=2.54) compared to those who reported sexual problems (M = 5.60; SD=3.00), with a large effect size (Cohen's d = 1.01 [95 % CI=-1.03, -0.98]; p < 0.001). Conclusion The SDS-3 has a unidimensional factor structure and appears to be valid and reliable for measuring sexual distress among individuals from different countries, gender identities, and sexual orientations.Peer reviewe
