Educational Activities of the First Special Meteor Expedition of the Russian Academy of Sciences in 1921–1922
Authors: Bershadskaya Svetlana V. ,   Krasnoyarsk State Agrarian University
Published: July 2024

Investigating the activities of the First Soviet Meteorite Expedition of 1921–1922, the paper aims to analyze the objectives of the expedition and fill in some gaps in the Quest for the Tunguska Meteorite. Aiming to recover either the fragments of the Tunguska meteorite or any other meteorite, the expedition was launched by the Russian Academy of Sciences and led by Leonid A. Kulik. The Yenissei province in Siberia was among several territories where the Expedition worked. The paper hypothesizes that the First Soviet Meteorite Expedition (1921– 1922) was a factor that contributed not only to the development of the new Soviet space science but became a unique driving force behind the vigorous attempt of the Soviet state to shift the backward mental paradigm full of prejudices and cognitive misconceptions and introduce the new one that prioritized scientific knowledge. The paper identifies the legal basis for the Expedition, its overall educational impact on ordinary people. The paper argues that the First Soviet Meteorite Expedition of 1921–1922 became a factor in transforming the sociocultural space and an incentive for further scientific research. The paper presents a historiographical review within the framework of the topic and introduces some new data obtained from the documents stored in the local archives (the towns of Yeniseisk and Minusinsk, Krasnoyarsk Territory).
Beliefs About and Motivation for Chinese EFL Learners’ English Language Learning: A Study Drawing on the Theory of Planned Behaviour
Authors: Gu Huiyuan ,   School of Foreign Languages, Guangzhou College of Technology and Business, No. 28, Shiling Nanhuan Road, Huadu District, Guangzhou, China
Published: July 2024

It is widely seen that research in the mainstream of education drew upon the Theory of Planned Behaviour (TPB) to examine learners’ beliefs about and intentions/motivations to learn a second or foreign language. However, such research in a Global Englishes (GE) context is scant. This study employed an adapted TPB model to explore the beliefs held by English language learners in China concerning GE and English language learning, and to anticipate the relationships between learners’ beliefs and their L2 (second language) motivation. The data was collected using questionnaires with 460 (N = 460) students at a university in China. Exploratory factor analysis and multiple regression analysis were used for data analysis. The results showed that the students’ beliefs formed five dimensions, namely, attitudes toward native English, attitudes toward China English, attitudes toward non-native English, subjective norm and self-efficacy. Two dimensions: attitudes toward native English and subjective norm were found to occupy a prominent place in students’ beliefs. As for their L2 motivation, three dimensions were identified, namely, integrative orientation, instrumental orientation and international posture. The results of regression analysis showed that learners’ L2 motivation were significantly shaped by some of their beliefs. Particularly, learners’ attitudes toward native English had a significant relationship with every dimension of their L2 motivation. And their normative beliefs (subjective norm) were found to have the most significant influence on their L2 motivation, indicating that the social pressure perceived by Chinese students played an important role in their L2 learning. The employment of Ajzen’s TPB model empirically supported to the validity of the theoretical model in examining learners’ beliefs and motivation.
MAJOR INORGANIC IONS IN BULK PRECIPITATION FROM COASTAL URBAN AND MONTANE ATLANTIC FOREST SITES IN SOUTHEASTERN BRAZIL
Authors: de Souza Patricia , de Mello William
Published: July 2024

Bulk precipitation (BP) samples were collected at two coastal urban sites and two montane Atlantic Forest (400 and 1000 m altitude) areas in southeastern Brazil from August 2008 to August 2009. These samples were analyzed for the major inorganic ions (H+, Na+, K+, Ca2+, Mg2+, Cl– and SO42–) found in rainwater. The concentrations of inorganic nitrogen species (NH4+, NO3– and NO2–) were compiled from a previous study. The volume-weighted mean (VWM) concentrations of inorganic ions differed spatially, with higher values at the coastal urban and coastal periurban sites. On a molar basis, Cl– and Na+ together comprised 60% of the total inorganic constituents at the coastal urban site and 34-42% at the other three sites, as it is the closest to the ocean. Magnesium was also primarily associated with sea-salt aerosol. Non-sea-salt (nss) fractions of K+, Ca2+ and SO42– comprised 68-93% of their VWM concentrations, indicating the contribution of natural (mostly biogenic) and anthropogenic (SO2 oxidation for the latter) sources. Finally, we found that the acidity of BP at the four sampling sites is primarily controlled by the NH4+, nss–Ca2+, nss–SO42–, and NO3– ions, resulting in VWM pH values ranging from 5.60 (lower montane forest) to 5.98 (coastal periurban site).

Metagenomic evaluation of bacteria in drinking water using full-length 16S rRNA amplicons
Authors: Taylor William , Devane Megan Louise , Russell Kathryn , Lin Susan , Roxburgh Colin , Williamson Judy , Gilpin Brent John
Published: July 2024

Escherichia coli and total coliforms are important tools for identifying potential faecal contamination in drinking water. However, metagenomics offers a powerful approach for delving deeper into a bacterial community when E. coli or total coliforms are detected. Metagenomics can identify microbes native to water systems, track community changes and potential pathogens introduced by contamination events, and evaluate the effectiveness of treatment processes. Here, we demonstrate how the dual application of traditional monitoring practices and metagenomics can improve monitoring and surveillance for water resource management. The robustness of long-read metagenomics across replicates is demonstrated by the effect and interaction between manganese filters and bacterial communities, as well as the impact of chlorination after coliform detection. These examples reveal how metagenomics can identify the complex bacterial communities in the distribution system and the source waters used to supply drinking water treatment plants (DWTPs). The knowledge gained increases confidence in identified causes and mitigations of potential contamination events. By exploring bacterial communities, we can gain additional insights into the impact of faecal contamination events and treatment processes. This insight enables more precise remediation actions and enhances confidence in communicating health risks to drinking water operators and the public.
La Abundancia y distribución de familias de poliquetos (Annelida: Polychaeta) asociados a sustratos artificiales en la bahía de Cartagena, Caribe Colombiano
Authors: Marin Amado Tatiana , Arregocés Silva Liseth Johana
Published: July 2024

La Bahía de Cartagena es considerada una de las puertas comerciales con más actividad turística y portuaria del país, destacando por su tráfico marítimo altamente dinámico. A lo largo de la bahía se reconoce la presencia de boyas de señalización marítima, que facilitan diversas operaciones náuticas y portuarias, proporcionando a su vez un hábitat ideal para una gran diversidad de invertebrados marinos, incluyendo la clase Polychaeta. Sin embargo, son pocos los estudios que reportan y analizan la dinámica de grupos taxonómicos como los poliquetos en sustratos artificiales en este sector portuario. Este estudio tuvo como objetivo caracterizar la abundancia y distribución de poliquetos asociados a las boyas de señalización del canal de acceso de la Bahía de Cartagena durante diferentes épocas climáticas. Durante el estudio se recolectaron un total de 1,144 ejemplares de poliquetos, registrándose las familias Capitellidae, Cirratulidae, Eunicidae, Hesionidae, Lumbrineridae, Nereididae, Sabellidae, Serpulidae y Syllidae. Las mayores abundancias se registraron en las épocas seca y de lluvia. En cuanto a la distribución de los ensamblajes de poliquetos en la bahía, se determinaron dos grupos de boyas: uno ubicado en la parte interna de la bahía y otro grupo más cercano al Canal del Dique. Esto indica una mayor variación en los ensamblajes ubicados en las estaciones con mayor influencia de la descarga de agua dulce, así como en aquellas influenciadas por aguas oceánicas en las áreas de mayor intercambio en la bahía. Las familias Nereididae, Syllidae y Cirratulidae presentaron variaciones debido a posibles cambios ambientales estacionales en el área de estudio.

Authors: Muniz Roosenilson , Matos Mateus J. , de N. de Oliveira Alex , Porto André L.M. , Pokutsa Alexander , Oliveira Francisco F. , Jimenez David E.Q. , Ferreira Irlon M.
Published: July 2024

:

Effective and “green” synthesis of tetraketone derivatives was elaborated. The last
compounds developed prominent bactericide activity against both MIC and MBC S. aureus
(ATCC-6538P) bacteria. The novelty of this approach is concluded in the application of
Al(OH)3 catalyst for the Knoevenagel-Michael cascade reaction of aromatic aldehydes and 1,3-
cyclic diketones in water. The process is chemoselective and affords high yield of tetraketones
under benign conditions. The catalyst maintained 80% of initial activity within four cycles.
The proposed method can be regarded as an alternative to the existing syntheses of biologically
active tetraketones that utilize homogeneous and expensive heterogeneous catalysts.
Detection of a Diagnostic Model and Comprehensive Examination of Diabetic Retinopathy Utilizing Genes Linked to Endoplasmic Reticulum Stress
Authors: Zhang Yan , Huang Yihong , Guo Maosheng , Chen Wanzhu , Wu Yuyu
Published: July 2024

Objectives:

The aim of this study was to reveal the biological functionalities associated
with endoplasmic reticulum stress (ERS)-related genes (ERSGs) in the context of diabetic
retinopathy (DR).

Methods:

Differentially expressed genes (DEGs) within the DR group and the Control group
were identified and then integrated with ERSGs. Gene Ontology (GO) and Gene Set Enrichment
Analysis (GSEA) methodologies were used to investigate potential biological mechanisms.
A diagnostic model for ERS and a nomogram were formulated based on biomarkers selected
through the Least Absolute Shrinkage and Selection Operator method. The diagnostic
efficacy of this model was thoroughly evaluated. ERS-associated subtypes were identified, and
the Single-Sample GSEA (ssGSEA) and CIBERSORT algorithms were used to assess immune
infiltration.

Results:

We identified 10 ERS-related DEGs (ERSRDEGs) within the DR Group. Subsequently,
a diagnostic model was constructed based on 5 ERS genes, namely CCND1, IGFBP2, TLR4,
TXNIP, and VIM. The validation analysis demonstrated the commendable diagnostic performance
of the model. Analysis of the ssGSEA immune characteristics revealed a positive correlation
in the DR group between myeloid-derived suppressor cells (MDSC), regulatory T cells
(Tregs), and CCND1 TXNIP. Furthermore, a significant negative correlation was observed between
central memory CD4 T cells and CCND1. In the context of CIBERSORT, the results indicated
a positive correlation between macrophages and IGFBP2, as well as Tregs and IGFBP2
in the DR group. Notably, a conspicuous negative correlation was identified between resting
mast cells and IGFBP2.

Conclusion:

The present study provides novel diagnostic biomarkers for DR from an ERS perspective.

Following the COVID-19 pandemic, OTT media consumption made its way
to India, revolutionizing the entertainment industry and altering how consumers
consumed entertainment. The lockdown has forced consumers to stay home. It has
brought about a paradigm shift in consumer behavior. The convenience of consuming
content on OTT platforms is driving the growth of this sector. The entertainment sector
is doing well with OTT services thanks to the rise in smartphone technical changes and
rising internet usage. Due to the abundance of spare time and appetite for entertainment
during the pandemic, OTT demand has been greatly influenced. India is a booming
market, surpassing Australia, Germany, and South Korea and will become the sixthlargest market in 2024 with a CAGR of 28.6%, as per the PricewaterhouseCoopers
report (PwC) published in August 2022. The OTT market continues to increase with
growing demand in India. The data were collected from secondary sources. The
research reveals that throughout the pandemic, both data usage and subscribers to the
internet increased. The main drivers of OTT growth are cheap data plans, broadband
penetration, and increasing smartphone sales. It aims to assess how OTT media
companies are engaged in their promotion and strategy plans from a socio-economic
perspective. The study shows that Hotstar has the highest market share, with 41%,
followed by Eros Now at 24%. The findings show that the lockdown has brought
socio-economic changes in the consumption patterns of consumers.

With innovations and developments in virtual reality as well as artificial
intelligence, machine learning, robotic process automation, the use of biosensors in
mobile technologies etc., healthcare executives are seizing the required benefits for
patients. The introduction of new business models by start-ups is causing considerable
disruptive innovation, and with investments totaling US$ 679 million in 2018, the
future appears bright. However, there is very little literature available on this
phenomenon. This study focuses on instigating the discussion in the healthcare sector
of India on the field of digital and disruptive innovation to spot what sort of agents of
disruption can help policymakers make informed decisions. The scope of the study
includes understanding the usage of this disruption, typically by the startups operating
in the field of healthcare and so on. Further investigation found ventures from these
companies in a digital context can be examined using the criteria of value for cost
towards health services, the presence of a robust and sustainable business model, and a
platform for customer-centric solutions. The approach was to see patterns that could
show incumbents in the industry relying more on sustainable innovation and creating
enough space to allow spectacular usage in the future with due changes in their
traditional setups.
The experience of teaching national history and the foundations of constitutional knowledge in the late 1930s early 1940s (using the example of railway schools in the Kursk region)
Authors: Korovin V. V. , Korovin R. V.
Published: July 2024

The relevance of the topic under discussion is determined by the significant social importance of school history education. Over thirty years of Russian society's and state's life in conditions of ideological and political diversity, as well as the complete erosion of the Western-scale liberal values, has led to most Russians realizing the need to adhere to traditional moral principles based on ideas of patriotism and humanism. The domestic education system is the main vehicle for this. Therefore, the controversial experience of teaching history in schools arouses professional interest among researchers and practicing teachers.

The purpose of the study is to reveal the peculiarities of teaching history in the pre–war years on the basis of archival documents and published materials on the example of departmental educational institutions of railway transport.

Objectives: to characterize the contradictions of the process of introducing historical and social sciences disciplines into school education; to reflect the role of historical knowledge in the patriotic education of the younger generation.

Methodology. The research was based on the principles of objectivity and historicism. To solve the tasks set by the author, the methods of historical-genetic, historical-systemic, historical-comparative, typological, retrospective were used.

Results. The study of the experience of teaching the historical and social sciences cycle of academic disciplines in the pre-war years on the example of departmental educational institutions of railway transport made it possible to objectively assess the impact of humanitarian training of students on the formation of their civic position and the education of patriotic feelings, which had a decisive impact on the behavior of graduates of railway schools during the period of military trials and subsequent restoration of the national economy.

Conclusions. The experience of teaching history and the foundations of constitutional knowledge accumulated in the pre-war period is worthy of application in the context of modern reform of historical education. Recognition of the leading role of national history in shaping the worldview of the younger generation requires a systematic approach in teaching and educating young people based on love and respect for their Homeland.
“Un buen lugar para vivir” Entrevista a Angelina Hernández Flores de la comunidad de Estación Queréndaro
Authors: Estrada Hernández Daniel
Published: July 2024

A finales del siglo XIX en la región del valle de Queréndaro se construyó la línea ferroviaria México- Apatzingán. Esta línea fue aprovechada por la hacienda de San José de Queréndaro para establecer una estación de carga para sus productos. En este periodo se introdujeron grandes avances tecnológicos en la región, provocando un aumento de la producción agrícola y venta de productos como el maíz en Morelia y la Ciudad de México. Es por este incremento en la economía local, la cercanía con el lago de Cuitzeo y el acceso a las ciudades de Morelia y de México, que se convirtió en un punto importante de llegada para las personas de la cuenca del lago de Cuitzeo. Es con los movimientos armados que tuvieron lugar durante las primeras décadas del siglo XX, que ocurre un gran desplazamiento de personas que huyeron de sus localidades para asegurar el bienestar de su familia. Ésta es una de las razones que la mayoría de las familias que conforman la población en Estación Queréndaro cuentan al hablar de su pasado familiar.

Published: July 2024

Stigma negatively impacts the quality of life of people living with HIV/AIDS, but there are few national studies dedicated to understanding the subjective dimension of this experience. Based on an unfolding of the Stigma Index 2.0 in Brazil, we aimed to qualitatively analyze the experiences of stigma narrated from the perspective of people living with HIV/AIDS. Of the 618 respondents from seven Brazilian capitals, 538 described in detail situations of stigma suffered by people with HIV/AIDS. A thematic analysis was performed, identifying that 76.4% of the reports had a negative content and 13.4% had an ambivalent content. The main characteristics of the stigma suffered were taboos, myths, ignorance or misinformation (22.4%); breach of confidentiality/exposure of serology (21.5%); the withdrawal or rupture of affective relationships/refusal of relationships (18.2%); and discrimination, neglect or violence by health professionals (16.6%). The context of health services was the main place of exposure (28.4%), with 13.9% of the reports verbalizing demands for public policies and support services. We discussed the implications of the results based on national and international studies, highlighting stigma as a creator of barriers in facing the HIV/AIDS epidemic.

Oral inclusion cysts are benign abnormalities and present spontaneous remission. The lesions have similar clinical characteristics, but have different locations and origins. Therefore, inclusion cysts are classified according to their location as: Epstein's Pearls, Bohn's Nodules and Dental Lamina Cyst. The objective of this study was to report a clinical case of inclusion cysts in the oral cavity of a four-month-old baby. This is a descriptive study, carried out in the municipality of Mato Verde-MG at Faculdade Verde Norte - FAVENORTE. Female patient, Caucasian, four months old, attended the FAVENORTE dental clinic taken by the person in charge, with the following main complaint "My daughter is teething". During intra-oral clinical examination, bilateral changes were observed in the region of primary molars located at the alveolar ridge line, measuring approximately 3 mm in diameter and whitish in color and asymptomatic. The changes are characteristic of Dental Lamina Cysts, the person responsible was reassured after diagnosis and the proposed treatment was quarterly clinical monitoring and guidance with gentle digital massage daily regarding the changes. It is of fundamental importance that professionals know the normal characteristics of the baby's oral cavity, only then will it be possible to reach accurate diagnoses related to changes in the baby's oral cavity, avoiding unnecessary therapeutic procedures.
The “Authenticity” of Cannibalism: Persisting Nineteenth-century Colonial Perceptions in the Present-day Tourism Dynamic of Lake Toba
Authors: Siallagan Kai
Published: July 2024

This paper discusses perceptions of the Batak of North Sumatra popular among nineteenth century European audiences and their continuity in the tourism industry and tourist descriptions. In particular, tourist dynamics in the Batak region of Lake Toba are contextualised and interpreted by identifying how local culture has reacted to tourist demand and tourist depictions of the Batak and their culture. The paper undertakes a historiographical survey of nineteenth century European writings that ascribe a “violent,” “primitive,” and “cannibalistic” character to the Batak to illustrate prevailing perceptions of the time. These findings are interpreted through a conceptual analysis that integrates Foucauldian discourse theory, Orientalism, Stuart Hall’s “the West and the Rest” as well as some elements of Marxist-Leninist material history. This analysis of modern tourism dynamics in Lake Toba is thus argued to illustrate how colonial perceptions and power relations have maintained currency through tourism.
Intersectionality in the Lives and Works of Mary Ann Shadd and Henry Bibb
Authors: Kochaniec Karleigh R.
Published: July 2024

Throughout the mid- to late nineteenth century, Henry Bibb and Mary Ann Shadd were highly accomplished and recognized abolitionists. Both Shadd and Bibb worked in the Detroit-Windsor region and resided in Windsor-Essex for a number of years. As part of their efforts, Shadd (The Provincial Freeman) and Bibb (The Voice of the Fugitive) were editors of their own newspapers that were targeted towards educating and informing Freedom Seekers. The abolitionists often worked together but also had a fair share of differences. Pre-existing research discusses the works of Shadd and Bibb, and the differences they demonstrated through their efforts, but little attention has been paid to how these differences were influenced by their lived experiences. This essay will use the individual lives and identities of Shadd and Bibb to observe the varying opinions and views as expressed in their newspapers. These conclusions will help determine how their identities influenced individuals who may have supported their views.
Amex: Discord and Unity in the Canadian Vietnam-Era Anti-Draft Movement, 1969-1971
Authors: Lanzkron-Tamarazo Doris R.
Published: July 2024

During the American Vietnam War of the 1960s and early 1970s, a movement dedicated to opposing the draft and assisting both draft dodgers and deserters emerged within Canada, where many of these war resisters immigrated. Exile groups were organizations in the anti-draft movement consisting entirely of American war resisters. One prominent exile newsletter was Amex: The American Expatriate in Canada. Amex’s reactions to events in the Canadian antidraft movement during its second volume (1969–1971) demonstrate how despite frequently criticizing other organizations and individuals within the movement, it ultimately advocated for unity. The newsletter's views on discord and unity within the anti-draft movement are representative of the larger movement’s success in maintaining cohesion despite disputes.

Introduction/Objective Patients with ankylosing spondylitis (AS) often experience chronic musculoskeletal pain, fatigue, and stiffness, which may contribute to psychological distress and sexual dysfunction. This study aims to assess prevalence of erectile dysfunction (ED) in patients with AS and identify potential associations between clinical parameters related to AS with the presence of ED. Methods Forty consecutive male patients with AS (mean age 42.8 ? 8.9 years) and 60 healthy men (mean age 38.9 ? 10.9 years) were included. All subjects filled out the International Index of Erectile Function (IIEF) questionnaire, as well as the Beck Anxiety Inventory (BAI) and the Beck Depression Inventory (BDI). In patients with AS disease activity was evaluated using the Ankylosing Spondylitis Disease Activity Score (ASDAS) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), functionality using the Bath Ankylosing Spondylitis Functional Index (BASFI), and quality of life using the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire. Results ED was significantly more frequent in patients with AS compared to controls (52.5%: 25%, p = 0.049). AS patients with ED had more severe symptoms of depression, than AS patients without ED (p = 0.034). According to ASQoL scores, patients with AS and ED had a worse quality of life, compared to patients with AS without ED (p = 0.022). The increase in one unit of ASQoL increased the odds of having ED for 17.5% (p = 0.035). Conclusion ASQoL score, as a measure of quality of life, was the only independently associated parameter with the presence of ED. It is necessary to raise awareness of ED in patients with AS.

In this study, we successfully produced Fe-based amorphous composite coatings on the surface of 45 steel using laser cladding technology, and the impact of the relative content of Cr and Mo elements on the microstructure, hardness, and wear resistance of composite coatings has been investigated. The results show that the microstructure of the coating changes from dendrite to amorphous nanocrystalline when the content of Cr and Mo is 20 and 15 wt. %, respectively. However, when the Mo element continues to be added, elemental segregation will be caused, resulting in a large number of brittle Fe–Cr–Mo intermetallic compounds and MoSi2 ceramic phases in the coating. Therefore, the appropriate element ratio can not only increase the amorphous phase content in the coating but also prevent elemental segregation. Among the three types of amorphous composite coatings studied, the Fe45Cr20Mo15B10Si10 (wt. %) composite coating exhibited the most favorable performance, primarily due to its highest amorphous content (43.33%). Through the interaction of the amorphous phase, α-Fe, Fe–Cr solid solution, and a small proportion of intermetallic compounds, this coating achieved a hardness of 1282.8 HV0.2, approximately five times that of the 45 steel substrate, and demonstrated superior wear resistance.

Background: The emerging technology to aid learning is the Learning Management Systems (LMS) that help to improve learning and teaching. There is an evolving new perspective to the concept of education with the recent fast development of technologies towards the generation of knowledge, the presentation of knowledge and the new way to reach knowledge. This formulated the increase adoption of Learning Management Systems (LMS) with various adoption patterns. Objectives: We narratively reviewed the Learning Management Systems in Tertiary Institutions in Nigeria from 2008 -January 2024 to generate evidence for planning and policy. Methods: The study was a narrative overview of studies related to learning management systems in tertiary institutions in Nigeria. Studies published between 2008- January 2024. The search terms included key words, set synonyms in databases relating to learning management systems. Three main databases: Google Scholar, PubMed, and CINAHL were considered. Abstract and full-text articles were obtained. Results: The geographical spread of the studies reviewed had national geographical spread (56.4%) across board with 25.6% of the studies carried out in institutions in the South-west geographical zone. The most popular instrument used in the studies is the questionnaire (56.4%), while data base constituted 12.8% of the studies. The majority (87.2%) were carried out in the university setting while 12.8% in the colleges of education. Table 6 presents the studies focus indicated that 20.5% of the studies assessed the usages of LMS, 10.2% Conclusion: The study largely suggested satisfaction of LMS with full positive impact on educational sectors promoting improvement in learning and teaching. However, many institutions are still far from its implementation.
Midwifery Care: Elevating Homebirth as a Safe, Cost-Effective Model for Healthy Pregnancies
Authors: A* Paul
Published: July 2024

In recent years, the conversation surrounding childbirth has evolved, with more families exploring options beyond the conventional hospital setting. Midwifery care and homebirths, though often misunderstood, present a compelling, safe, and cost-effective model that aligns with both physiological and psychological well-being of mothers and infants. As a public health professional and a mother who has personally experienced the transformative power of midwifery care, I believe it’s time to elevate homebirth as a mainstream option.

Published: July 2024

The field of dentistry is undergoing quick and dynamic changes, requiring the integration of digital technology and human resource management to ensure sustainable businesses. There is a growing need for leadership to enhance diversity and equality in the workplace. Leadership in diversity and equality significantly impact dental members’ satisfaction and performance. This qualitative study uses a systematic review utilizing reliable sources, including Google Scholar, Web of Science (WOS), and Scopus databases. The researchers gathered scholarly publications published between 2019 and 2024 through purposive sampling. The results demonstrate that enhancing human resource management (HRM) in leadership for dentistry can enhance ethical considerations and ensure a resilient dental workforce that embraces diversity and equality guided by leadership principles. The way to promote gender equality is to avoid words like “women’s leadership” or “men’s leadership” that reinforce gender stereotypes but suggest using leadership in diversity and equality that affect satisfaction and human resource performance. Leadership for diversity and quality has been a prominent topic of discussion to improve human resource satisfaction and performance in dental management settings and dentistry. It is suggested that questionnaires, interviews, or focus groups should be explored as methods to get more insights from participants for further studies. The findings could be applied to any company and organization, not only in dentistry and dental management settings.
El fracaso histórico de la política para la autosuficiencia agroalimentaria en México y su perspectiva hacia la próxima década (2030)
Authors: Díaz Castellanos Rafael
Published: July 2024

Históricamente, la producción de granos en México ha sido insuficiente para atender su demanda interna. Por eso, esta investigación, secuencial mixta, tiene como objetivo analizar el déficit de la producción nacional de granos, la dependencia a su importación (desde los últimos 40 años) y pronosticar su alcance en la próxima década. Para ello, se demuestra que de 1980 al 2021 la superficie dedicada a la producción de arroz, avena, cebada, frijol, maíz, soya, sorgo y trigo se redujo 7 %, su producción incrementó 72 % y la productividad (toneladas/hectárea) acumulada de los 8 productos aumentó 47 %; en contraste, las importaciones aumentaron 210 % (en 1980 representaron el 36 % respecto a la producción nacional, y para el 2020 fue del 66 %). Con el software Minitab se aplicaron modelos predictivos de series de tiempo de las variables en estudio para pronosticar su desempeño para el año 2030. Los resultados demuestran (respecto a 1980) la reducción del 12 % de la superficie total para esta actividad en el territorio nacional, el incremento de la producción del 96 % y la escalada total de sus importaciones hasta del 253 %.
