El estudio de las conductas antisociales en adolescentes y jóvenes es de gran relevancia para transitar a una sociedad con cada vez menos delitos y actos no acordes a los ideales de la humanidad. La experiencia cotidiana y las cifras de los organismos oficiales en México demuestran que es necesario trabajar en esta área, de hecho, desde diferentes propuestas y planes gubernamentales, a nivel nacional y estatal, las acciones para prevenir la violencia y el tránsito hacia una cultura de la paz son tareas resaltadas como necesarias. Estudiar las conductas antisociales también tiene una implicación académica: en la literatura se ha reconocido que ciertas conductas antisociales son probabilizadoras de actos delictivos posteriores; además, se tiene evidencia de que tales conductas se incrementan en la adolescencia. En México la educación secundaria puede cursarse en diferentes modalidades. Generalmente, existen escuelas donde cada una de las asignaturas son impartidas por un maestro diferente y otra modalidad en la que todas las asignaturas son impartidas por un solo profesor. Aunque la experiencia sugiere que los alumnos se conducen diferente en función del tipo de modalidad en la que estudian, pocos son los estudios que analicen cómo se comportan estudiantes de escuelas secundarias generales y alumnos de telesecundaria. Por tales motivos, el presente trabajo tuvo como finalidad reconocer los tipos de conductas antisociales que presentan los alumnos de nivel secundaria en dos de las modalidades que este nivel educativo puede asumir: secundarias generales y telesecundarias. La investigación se realizó con más de 800 participantes y los resultados mostraron diferencias en la frecuencia de conductas antisociales entre alumnos de escuelas generales y telesecundarias.

Published: October 2024

Abordar el delito implica estar consciente del enfoque que se utiliza y de las limitaciones que implica cada una de las herramientas teóricas para explicarlo, ya sea filosófica, social o legalmente. Una breve revisión de tales enfoques es por ello, necesario en primera instancia. Posteriormente se aborda la delincuencia en Guanajuato y el Bajío. La percepción gubernamental guanajuatense es que existe una vecindad con entidades más violentas y en consecuencia hay contacto y vínculos territoriales que explican la distribución geográfica de la misma. A la vez, evidencias recientes de que la delincuencia tiene mayor expresión e intensidad en aquellos municipios con mayores índices de urbanización y con mayor intensidad de actividades económicas. Por lo que el objetivo general del proyecto es encontrar el tipo de asociación estadística entre la contigüidad geográfica, la dinámica socioeconómica y los actos delictivos en los 84 municipios de Guanajuato y aquellos que tiene vecindad en los estados de Jalisco, Michoacán, Querétaro, San Luis Potosí y Zacatecas en el año censal 2020, a fin de comprender el peso de la causalidad involucrada. La hipótesis es que la asociación más importante entre municipios colindantes con el Estado de Guanajuato es de menor intensidad, que aquellos con una contigüidad con municipios de mayor dinámica económica. La investigación parte de observar que todas las entidades estatales vecinas sumaron poco menos la cantidad de fallecimientos de Guanajuato solo, cuyo incremento es, hasta hoy en día, el más alto del país.

Concebir el lenguaje en su multiplicidad, reconocer sus diversas formas en las situaciones sociales de comunicación, permite una perspectiva funcional del lenguaje en la que se estudian los códigos usados en los eventos comunicativos, su rol central y activo en la creación de los significados compartidos por los seres humanos para comprendernos. En esta investigación se describe, explica y relaciona los postulados teóricometodológicos de la semiótica social (SS) y el análisis crítico del discurso (ACD) para demostrar, mediante un procedimiento de análisis derivado de ellos, cómo se interrelacionan y permiten la comprensión e interpretación de textos en contextos. El análisis del lenguaje como recurso semiótico abarcó desde la definición del discurso estudiado con el fin de establecer la relación de los textos con sus contextos global y del evento, el estudio de las estructuras implicadas en esa relación: superestructura pragmática, macroestructura semántica y microestructura sintáctica, hasta, en y desde ellas el establecimiento del género, el estilo y la modalidad del discurso en textos de la revista feminista mexicana Fem.
Downslope Wind Verification of the National Blend of Models v4.0 Across the Northern Front Range of Colorado During the 2020/2021 Cool Season
Authors: Larson McKenzie L. , Winters Andrew C. , Schlatter Paul T.
Published: October 2024

Downslope windstorms are common leeward of the Rocky Mountains across the High Plains of Colorado during October through March and can cause property damage and travel disruptions. This region is renowned for two primary types of strong downslope winds: (1) chinooks that feature warm, dry winds and are often associated with the development of mountain waves, and (2) boras that are colder and often associated with the passage of a mid- and upper-level trough. The National Blend of Models (NBM) is regularly utilized by forecasters at the National Weather Service Forecast Office (WFO) in Boulder and is one tool used by the WFO to forecast downslope windstorms. No study, however, has quantified the performance of the NBM during downslope windstorms along the Colorado Front Range. In this exploratory study, downslope windstorms from October 2020 through May 2021 were identified using ten observation sites along the Colorado Front Range. Windstorms were subsequently analyzed to quantify forecast statistics of wind speeds and gusts during windstorms to provide a better understanding of NBM v4.0 performance. On average, we found that the overall maximum magnitudes of wind speeds and gusts are on average 38% and 35% too low in the NBM output, respectively, when averaged across 24 to 72-h lead times. Weather and Research Forecasting (WRF) model simulations of varying vertical resolution were also completed to determine if WRF, a constituent model of the NBM, could provide a robust representation of select downslope windstorms across the Colorado Front Range.
Glial Control of Cortical Neuronal Circuit Maturation and Plasticity
Authors: Faust Travis E. , Devlin Benjamin A. , Farhy-Tselnicker Isabella , Ferro Austin , Postolache Maggie , Xin Wendy
Published: October 2024

The brain is a highly adaptable organ that is molded by experience throughout life. Although the field of neuroscience has historically focused on intrinsic neuronal mechanisms of plasticity, there is growing evidence that multiple glial populations regulate the timing and extent of neuronal plasticity, particularly over the course of development. This review highlights recent discoveries on the role of glial cells in the establishment of cortical circuits and the regulation of experience-dependent neuronal plasticity during critical periods of neurodevelopment. These studies provide strong evidence that neuronal circuit maturation and plasticity are non-cell autonomous processes that require both glial–neuronal and glial–glial cross talk to proceed. We conclude by discussing open questions that will continue to guide research in this nascent field.
Learning and Control in Motor Cortex across Cell Types and Scales
Authors: Economo Michael N. , Komiyama Takaki , Kubota Yoshiyuki , Schiller Jackie
Published: October 2024

The motor cortex is essential for controlling the flexible movements underlying complex behaviors. Behavioral flexibility involves the ability to integrate and refine new movements, thereby expanding an animal's repertoire. This review discusses recent strides in motor learning mechanisms across spatial and temporal scales, describing how neural networks are remodeled at the level of synapses, cell types, and circuits and across time as animals' learn new skills. It highlights how changes at each scale contribute to the evolving structure and function of neural circuits that accompanies the expansion and refinement of motor skills. We review new findings highlighted by advanced imaging techniques that have opened new vistas in optical physiology and neuroanatomy, revealing the complexity and adaptability of motor cortical circuits, crucial for learning and control. At the structural level, we explore the dynamic regulation of dendritic spines mediating corticocortical and thalamocortical inputs to the motor cortex. We delve into the role of perisynaptic astrocyte processes in maintaining synaptic stability during learning. We also examine the functional diversity among pyramidal neuron subtypes, their dendritic computations and unique contributions to single cell and network function. Further, we highlight how cortical activation is characterized by increased consistency and reduced strength as new movements are learned and how external inputs contribute to these changes. Finally, we consider the motor cortex's necessity as movements unfold over long time scales. These insights will continue to drive new research directions, enhancing our understanding of motor cortical circuit transformations that underpin behavioral changes expressed throughout an animal's life.
Aperiodic EEG Predicts Variability of Visual Temporal Processing
Authors: Deodato Michele , Melcher David
Published: October 2024

The human brain exhibits both oscillatory and aperiodic, or 1/
f
, activity. Although a large body of research has focused on the relationship between brain rhythms and sensory processes, aperiodic activity has often been overlooked as functionally irrelevant. Prompted by recent findings linking aperiodic activity to the balance between neural excitation and inhibition, we investigated its effects on the temporal resolution of perception. We recorded electroencephalography (EEG) from participants (both sexes) during the resting state and a task in which they detected the presence of two flashes separated by variable interstimulus intervals. Two-flash discrimination accuracy typically follows a sigmoid function whose steepness reflects perceptual variability or inconsistent integration/segregation of the stimuli. We found that individual differences in the steepness of the psychometric function correlated with EEG aperiodic exponents over posterior scalp sites. In other words, participants with flatter EEG spectra (i.e., greater neural excitation) exhibited increased sensory noise, resulting in shallower psychometric curves. Our finding suggests that aperiodic EEG is linked to sensory integration processes usually attributed to the rhythmic inhibition of neural oscillations. Overall, this correspondence between aperiodic neural excitation and behavioral measures of sensory noise provides a more comprehensive explanation of the relationship between brain activity and sensory integration and represents an important extension to theories of how the brain samples sensory input over time.
Model or Menace?
Authors: Sae-Saue Jayson Gonzales
Published: October 2024

This article examines US and Mexican racial discourses concerning Chinese and Mexican immigrant labor in the early twentieth century. In the era of Asian exclusion, US business and government leaders ascribed favorable racial identities to Mexican workers in contrast to the perceived social and economic threats associated with Chinese. These discourses affected the domestic labor market, which rapidly absorbed Mexicans as it expunged Chinese. At the same time, US business interests in Baja California, needing cheap labor, reinvented the Chinese worker as a racialized model of production in the face of Mexico’s anti-Asian discourses and politics. These discursive constructions of Chinese and Mexicans as distinct representations of either model or menacing otherness reveal how the US business elite and the state assigned differentiated yet interrelated values to these labor groups on a transnational scale. The labor formations of the California–Baja California border region highlight the confluence of shifting racial ideologies concerning Chinese and Mexican workers and make visible the mutually constitutive histories of their early diasporas across the US-Mexico borderlands.
Efficacy and safety of vancomycin for local application in the prevention of surgical site infection after joint arthroplasty: a systematic review and meta-analysis
Authors: Xie Chengxin , Zhang Liwei , Zhang Dehua , Tao Lingjian , Zhao Yong , Luo Hua
Published: October 2024

Purpose

The aim of this systematic review and meta-analysis is to explore the effect of topical vancomycin powder (VP) in surgical site infection (SSI) prevention and adverse events after joint arthroplasty and to provide a specific theoretical basis for clinical treatment.

Methods

The review process was conducted according to the PRISMA guidelines. Two independent researchers meticulously screened the literature based on predefined inclusion and exclusion criteria, evaluated the quality of the selected studies, and extracted relevant data. Data analysis was conducted using RevMan 5.4 software.

Results

This meta-analysis included 24 studies encompassing a total of 34 811 patients. The pooled analysis showed that the topical administration of VP significantly reduced the incidence of SSI. Subgroup analyses by doses, type of joint (hip and knee), and type of surgery (primary and revision) confirmed that vancomycin consistently lowered SSI rates. Moreover, the incidence of SSI caused by gram-negative germs and gram-positive germs decreased following the use of VP, although the reduction was not significant for infections caused by MRSA. However, the use of VP was associated with a significant increase in sterile complications at the incision site and delayed incision healing.

Conclusion

The topical application of VP is effective in reducing the incidence of infections following joint arthroplasty. Despite an increased risk of complications such as delayed healing of incisions, the pros and cons should be weighed in clinical decision-making. However, it should not be discarded due to side effects.

Published: October 2024

This review highlights the pivotal role of Kaplan fibers (KFs) in knee stability, particularly in the anterolateral aspect. Studies reveal their complex anatomy with varying attachments to the distal femur, demonstrating a significant impact on knee joint mechanics across different populations.

Investigations into the biomechanics of KFs show their crucial role in maintaining rotational stability of the knee, especially during rotational movements. Their synergistic function with other knee structures, like the anterolateral ligament, is emphasized, underscoring their importance in knee integrity and function.

MRI emerges as a key tool in detecting KFs, with varying visibility and prevalence of injuries. The review discusses the development of MRI criteria for accurate diagnosis, highlighting the need for further research to refine these criteria and understand the interplay between KF injuries, anterior cruciate ligament (ACL) ruptures, and associated knee pathologies.

The review covers various lateral extra-articular tenodesis (LET) techniques used to address residual laxity and instability following ACL reconstruction. Among them, the modified Lemaire technique, which resembles the anatomical and functional characteristics of distal KFs, shows effectiveness in reducing internal rotation and residual laxity.

The review emphasizes the need for further research to understand the healing dynamics of KF injuries and the efficacy of different LET techniques. It suggests that a comprehensive approach, considering both biomechanical and clinical aspects, is crucial for advancing knee joint health and rehabilitation.

Para ello, en primer lugar, se presenta información que refleja la cantidad de residuos que se generan y la cantidad de estos que son separados. A partir de esta información se ilustra el aporte que desde la economía circular se propone para la reducción de la cantidad de residuos con la aplicación de las “Rs” y como desde el rol, bien sea como consumidor o productor se puede contribuir a su aplicación. La participación del Gobierno es determinante en la consecución de los objetivos y por eso se menciona la ley 7 del 8 de abril de 2022, ley de residuos y suelos contaminados para una economía circular y algunas disposiciones normativas de los organismos de la Unión Europea que forjan el camino hacia la reducción de residuos.
Demystifying Rising Income Inequality Influence on Shadow Economy: Empirical Evidence from Nigeria
Authors: Haruna Emmanuel Umoru , Alhassan Usman
Published: October 2024

We investigate whether rising income disparity contributes to the proliferation of shadow economic activities in Nigeria. The study uses data from 1991 to 2018 and adopts the Auto-regressive Distributed Lags (ARDL) cointegration approach to study the effects of income inequality on the shadow economy in both the short- and the long-run. Our results show that the Nigerian shadow economy responds positively to increases in income inequality, especially in the short run. We also find that the large income disparity in Nigeria drives the poor into informal economic activity, primarily for survival, and that unemployment partly contributes to informality. Our findings suggest that unemployment may be both a result and a cause of rising income disparity in Nigeria, leading to an expansion of the shadow economy. These findings indicate that regulating the proliferation of shadow economic activities in Nigeria will necessitate, among other things, the implementation of measures to reduce income gaps, such as stronger institutional frameworks and the expansion of financial intermediation services such as credit supply to the informal sectors.
The Ability to Work Remotely: Measures and Implications
Authors: Langemeier Kathryn , Tito Maria D.
Published: October 2024

Our paper explores how the ability to work remotely has changed over time, its relationship with demographic characteristics and employment outcomes, and the role it played during the pandemic recession. We focus on two different remote work indexes, a measure of “no physical presence”—proposed by Dingel and Neiman (2020)—and a measure of “remote communications”—presented by Montenovo et al. (2020). While the two measures suggest a similar prevalence of remote work in recent years and display fairly similar behaviors across demographic groups and in terms of wage and employment outcomes, their evolution is significantly different. While the share of occupations that require no physical presence has remained relatively constant since July 2003, the share of those occupations featuring remote communications increased more than 40 percentage points over the same period. Those differing evolutions paint a starkly different picture of the role of remote work during the pandemic: Compared to a counterfactual scenario that keeps the remote classification constant at the 2004 levels for each measure, the index of no physical presence suggests that there would have been little changes in terms of aggregate hours losses during the pandemic, while the index of remote communications points to much larger declines in aggregate hours. Even without much change in the ability of working remotely, the trend towards more remote work underscores the importance of the hours margin as an additional dimension for the realization of gains from working at home.
Cardiovascular Medical Device Failure: Using Five-Week Moving Averages To Assess Adverse Event Report Data
Authors: Zhou Elsa S. , Bhatia Sujata K.
Published: October 2024

The COVID-19 pandemic had a variety of effects on the healthcare system, including the interruption of regular cardiology practices. We examined the pandemic’s effects on cardiovascular medical device failure by investigating trends in the number of reports of adverse events of several cardiovascular medical devices over the span of three years, including the first year of the pandemic. Specifically, we used data from the FDA’s MAUDE database, calculating the five-week moving average of adverse events associated with both implantable cardioverter defibrillators and coronary drug-eluting stents. We previously reported a 46% decrease in reported deaths attributed to ICDs and a 27% decrease in reported injuries attributed to coronary DES. We use a five-week moving average and confirm a 46% decrease in reported deaths attributed to ICDs, report a 9.8% increase in ICD-attributed malfunctions, and confirm a 27% decrease in reported injuries attributed to coronary DES. The different effects of the pandemic on these adverse event report trends, even within one device, show there are more factors to consider than explanations such as underreporting which would be expected to affect most medical devices relatively homogeneously.

Published: October 2024

The purpose of this paper is to analyze empirically the contribution of tertiary level education by fields on economic growth for 29 developed and 25 developing countries over the period 1998-2012. Using the two-step System Generalized Method of Moments (GMM), we find that in the developed countries graduates from science faculties make the most contribution to economic growth, but in developing countries graduates from education, humanities and social sciences faculties contributed the most to economic growth. In addition, we focus on the effect of distribution of tertiary level graduates among different fields on economic growth and our results imply that, having human capital from different fields in both developed and developing countries positively affects economic growth.
The Canadian-Mexico Commodity Trade and Exchange Rate Uncertainty: An Asymmetric Analysis
Authors: Bahmani-Oskooee Mohsen , Harvey Hanafiah
Published: October 2024

A previous study assessed asymmetric effects of the real peso-dollar volatility on trade flows between Mexico and the U.S., two members of the former NAFTA. We now expand that analysis by considering the trade flows between Mexico and Canada. Estimating traditional linear models did not yield much significant effects of the real peso-Canadian dollar volatility on trade flows between the two countries. However, estimating a nonlinear model revealed that four out of 16 Canadian exporting industries to Mexico and 10 out of 21 Mexican industries to Canada were affected asymmetrically. While the export shares of four Canadian industries was 28.2%, that of 10 Mexican industries, with a non-linear model was 80%. Additionally, while increased volatility boosted exports of four US industries, it had no significant effects on the exports of 10 Mexican industries. In contrast, decreased volatility had no significant effects on the US exporting industries, but it had favorable impact on Mexican exporting industries.
Changing the Discount Rate by Adjusting the Pure Rate of Time Preference
Authors: Lee Jamie , McKitrick Ross , Stengos Thanasis
Published: October 2024

The Ramsey (1928) equation decomposes the real discount rate into the pure rate of time preference plus a term that accounts for the changing marginal utility of consumption. Discussions about the appropriate discount rate to apply in Cost Benefit Analysis sometimes refer to variations induced by alternative values of the pure rate of time preference as if the two vary on a one-to-one basis. But the optimal consumption path, which determines the marginal product of capital and hence the discount rate, depends on the rate of time preference. Hence the discount rate depends on time preference through the marginal utility term. We derive an analytical expression of this relationship and show that the derivative of the discount rate with respect to time preference only equals unity in the steady state and converges from below. We estimate the derivative using US data from 1930 to 2015. Based on a semi-parametric regression model with time-varying coefficients we find it is about 0.9, but we cannot rule out 1.0 being included in the 95% confidence interval. The implied pure rate of time preference after 1980 is about 1.6 percent.
Estrategia didáctica para la enseñanza de gestión de colecciones digitales y la digitalización de material en estado de conservación
Authors: Guadamuz Villalobos Jairo Andrés
Published: October 2024

Bibliographic collections are part of the academic and cultural heritage of our society, their preservation and conservation is of utmost importance so that the information they contain can be accessible to future generations. Safeguarding information is one of the most important tasks of libraries. However, a document that must be digitized for preservation can be subjected to a lot of stress if the process is carried out with commercial scanning devices. It is for this reason that it is necessary to train future information professionals in the process of digitizing bibliographic material in a state of conservation. To achieve this, a teaching strategy was created that includes master classes on basic principles of converting analog to digital material, resolutions for each type of material, white balance and color theory. In addition, as part of the teaching strategy, videos were created that explain the proper handling of the material when digitizing, the camera configuration, the capture process, the editing of the material and the creation of an electronic document. Finally, the students participated in a virtual practical workshop where, by themselves, they completed the process of digitizing bibliographic material using what they learned in class. To evaluate the experience, an instrument was provided to the group of students who participated in the teaching strategy, thus allowing their opinion to be known about the level of approach to the topic that they may have had.

Anesthetic management of acute embolic stroke following Non-ST-Elevation Myocardial Infarction: a case report
Authors: Oweisi MD Ayman , Olson DO Jared , Cheney MD Clayton
Published: October 2024

The management of patients with severe coronary artery disease (CAD) and acute heart failure following myocardial infarction presents significant challenges. We report the case of a 66-year-old male who developed an acute embolic stroke, possibly due to a cardiogenic embolism, following coronary angiography and cardiac catheterization for a non-ST-elevation myocardial infarction (NSTEMI). The NSTEMI resulted in ischemic cardiomyopathy and left ventricular dysfunction. During an urgent thrombectomy under general anesthesia, the patient required careful propofol dosing to avoid exacerbating his new-onset heart failure. Vasoactive medications, including norepinephrine, epinephrine, phenylephrine, and dobutamine, were used to maintain hemodynamic stability and support myocardial contractility. A thorough understanding of cardiac perfusion dynamics was crucial for the successful anesthetic management of this complex case. This report highlights the importance of individualized anesthetic approaches and the judicious use of vasoactive agents in patients with severe CAD and acute heart failure.
Magnetotactic bacteria and magnetosomes – an overview
Authors: Hossain Samiha , Bahreini Beatriz , Pasteur Emmanuell , Sadoh Airefetalo , Bala Rishi , M Ravindra Nuggehalli
Published: October 2024

Magnetotactic bacteria are a diverse group of prokaryotes that create intracellular, membrane-bound organelles containing magnetic minerals known as magnetosomes. These minerals have a sdpecialized purpose with the use of mineral crystals such as magnetite (Fe3O4) or greigite (Fe3S4). Due to the stability of these crystal structures, the bacteria can orient themselves with the Earth’s geomagnetic field lines, functioning as compass needles to help them locate suitable environments to inhabit. The objective of this review, based on previous progressions in this area of study, is focused on presenting a comprehensive summary of MTB, its abundance and magnetosome formation. Moreover, the effects of certain environmental factors, as well as their significance and applications in material science, medicine, and biotechnology, are elucidated.
Limites da tolerância entre diversidades e desigualdades
Authors: De Lisboa Lustosa Lopes Antonio , Xavier de Carvalho Magno
Published: October 2024

Contemporaneamente, as sociedades vão se tornando cada vez mais complexas e multiculturais. A diversidade, em suas diversas expressões, figura um mosaico multicolorido característico da modernidade. No entanto, ao passo que cresce a diversidade, dilata-se, com grande força, o fenômeno da intolerância que destrói a possibilidade da boa convivência em sociedade. O cenário funesto esboçado com as últimas eleições do Brasil, em outubro de 2022, que ainda repercute e parece infindável, revela os perigos da intolerância. Nesse sentido, nosso artigo buscará refletir acerca do tema da tolerância, ultrapassando a sua acepção etimológica original, que expressa passividade, de modo a buscar evidenciar os limites para tal postura, isto é, tudo aquilo que atenta contra a dignidade da pessoa humana. Para isso, ajudar-nos-á a reflexão do professor Clodoaldo Meneguello Cardoso (2003), que trabalha o tema a partir do chão latino-americano.

Published: October 2024

Este artigo tem como objetivo apresentar um estudo sobre a dimensão moral do voto na perspectiva da teologia católica. Mais especificamente, a investigação abordará o que é frequentemente designado por voto útil, ou seja, o ato de votar num candidato que não é exatamente o preferido, mas que resultaria, de acordo com um ponto de vista específico, num mal menor para a sociedade. A questão principal do artigo é a seguinte: o voto útil deve ser considerado uma obrigação moral entre aqueles que têm a Doutrina Social da Igreja como referência para a vida ética?
Imaginário social, ambientes digitais e algoritmos

Published: October 2024

Este artigo tem dois objetivos centrais. Por um lado, refletir teoricamente sobre as articulações entre a noção de imaginários sociais (principalmente as ideias propostas por Cornelius Castoriadis) com as tecnologias digitais, em particular o software e os algoritmos informáticos. Essa reflexão é extremamente necessária, no contexto da existência de um imaginário central do capitalismo contemporâneo: as tecnologias digitais como inteligência objetiva e neutra. O capitalismo se renova constantemente. Por isso, a apropriação coletiva destas tecnologias exige a elucidação das condições específicas através das quais esse processo ocorre. Além disso, outro objetivo deste artigo é destacar a relevância do pensamento de Castoriadis e sua contribuição para a criação de imaginários e projetos que possibilitem alternativas tecnopolíticas à mercantilização da vida.

This study aims to assess the current state of ethnozoological research in Brazil. Sistematic review was conducted using the Web of Science and Scopus databases, encompassing all publications available until December 2022. The selected articles, written in various languages, consist of data obtained directly by the researcher, offering taxonomic descriptions of species and their respective uses. 85 articles were selected to construct a distribution map of ethnozoological studies, categorizing them based on their use. The Spearman's correlation test and the Kruskal-Wallis test, were applied to identify patterns within the data on use, number of studies and zoological class. Spearman's correlation indicated a positive relationship between the sum of uses and the number of studies conducted. The Kruskal-Wallis test revealed variations in the average number of studies and total uses across different zoological classes. The thematic classification of articles included general ethnozoology, specialized ethnozoology, general medicinal use, specific medicinal use, and hunting. Results showed a consistent increase in publications, with the Northeast region and the Caatinga biome featuring prominently. The reviewed papers encompassed 829 species, demonstrating greater representation in the food and medicinal categories. Ichthyofauna and avifauna, exhibited the highest species number. Our study highlights the utilitarian versatility of herpetofauna and mammal fauna. The classes Asteroidea, Bivalvia, Chilopoda, Echinoidea, and Hydrozoa, were identified as having below-average representation in terms of studies and use associations. In conclusion, the revision advocates for investigations with a collaborative bias among research groups from different biomes, to aid in reducing centralized studies in specific geographical areas.
Discursive Words in the Karelian Language: Towards the Formulation of the Question
Authors: Patroeva Natalya V. , Pashkova Tatyana V.
Published: October 2024

Introduction. Currently, discursive words in the Karelian language have not been subjected to a comprehensive study, and many questions on the categories of connectors of both closely related and unrelated languages of the world cause controversy and discussion. The solution of these controversial issues is supposed to be possible through the accumulation of a significant amount of linguistic material, as well as data on the pragmatics, evolution, semantics and etymology of discursive words. The purpose of the study is to conduct a comprehensive analysis of the official parts of speech (their composition, functions and semantics) in three dialects of the Karelian language (Karelian proper, Livvikov, Ludikov ones) within the framework of the project “Discursive words in the Karelian language: a comparative typological aspect”.
Materials and Methods. The study of Karelian syntax was carried out in terms of comparison with the grammatical structure of the Finnish language, which is closely related to Karelian, and the Russian language. The materials for the research were Karelian dictionaries (dialect and new-written) and samples of dialect Karelian speech, which allow to identify the composition and semantics of discursive words, to determine their origin in dialects and dialects of the Karelian language. General scientific and specifically linguistic (comparative-typological, lexicographic, etymological, comparative-historical) methods were applied.
Results and Discussion. The most important result of the conducted research is a comprehensive analysis of discursive words in the dialects of the Karelian language with the use of data from related (Finnish, Veps) and unrelated (Russian) languages.
Conclusion. The results of the study contribute to the study of pragmatics, evolution, semantics and etymology of discursive words of the Karelian language, and help to clarify the issue of connector categories in closely related and unrelated languages of the world.
Proper Names in the Poetry of Marina Slugina
Authors: Sheyanova Svetlana V.
Published: October 2024

Introduction. In Finno-Ugric studies, there is a noticeable lack of research on literary onomastics, and the semantic functions of proper names within the structure of literary texts are insufficiently explored. The purpose of this article is to identify the types of onyms in the works of M. Slugina and to determine their functional and semantic features.
Materials and Methods. The study material consisted of works by M. Slugina from the poetry collection “Tyust” (“Shades”). The research employed traditional linguistic methods: descriptive, functional-semantic, comparative-historical, as well as modern approaches to the study of literary texts – interpretative and gender-based.
Results and Discussion. The types of onyms in M. Slugina's poetic texts have been identified, the core and periphery of the onomastic space in her works have been outlined, and a semantic analysis of onomastic vocabulary has been conducted. It is noted that the core of the onomastic space in M. Slugina's poetry consists of anthroponyms and toponyms (including oikonyms, choronyms, and hydronyms), while the periphery includes mythonyms, zoononyms, urbanonyms, dryonyms, theonyms, cosmonyms, hemeronyms, chrononyms, geortonyms, and religious-cultural toponyms. In the author's works, these serve text-forming, stylistic (informational-stylistic, emotional-stylistic), evaluative, aesthetic, symbolic, and conceptual functions.
Conclusion. The results of this study can be useful for further research into poetic onomastics within Finno-Ugric linguistics.
Prediction of body weight of mixed breeds of pigs in Nigeria through morpho-biometric traits using classification and regression tree models

Abstract. The study was conducted to predict the body weight of mixed breeds of pigs in Nigeria through morpho-biometric traits (body length, chest girth, height at withers, ear length, head length, foreleg length, and hind leg length) using classification and regression tree models. The data were produced using 500 randomly selected mixed breeds of pigs from various farms in five Local Government Areas of Kaduna State, North West Nigeria. The collected data were analysed using the Statistical Package for Social Sciences (SPSS, 2016). Body weight correlated well with morphometric characteristics except with foreleg length, which had a low correlation and no significant (P>0.05) difference. Two body dimensions were shown to be more effective in predicting the body weight of the mixed-breeds based on the significance of the independent variables: chest girth and body length. The largest dividing variable was determined to be chest girth, which explained roughly 88.60 % of the difference in body weight. The decision tree model revealed that pigs with chest girth or chest circumference greater than 76.00 cm are expected to have a higher body weight, which livestock producers and researchers could use to determine the feed amount, drug dose, and market price of an animal, as well as the management, selection, and genetic improvement of mixed breeds of pigs in Nigeria.
Impact of soil herbicides on weeds during pricking out Rosa canina L. seedlings
Authors: Angelova D. , Stanev S.
Published: October 2024

Abstract. During the period 2020-2021 the Institute for roses and aromatic plants – Kazanlak completed a field experiment on producing Rosa canina L. seedlings “Plovdiv 1” variety using herbicides. Herbicide efficiency and selectivity of flumioxazin (Pledge 50 WP) and pendimethalin (Stomp aqua) were tested. The soil herbicides were imported before pricking out Rosa canina L. seedlings. Results show that Pledge 50 WP is successfully fighting the annual species established in the experimental field (Amaranthus retroflexus L., Chenopodium album L., Polygonum aviculare L., Setaria glauca L.). Stomp aqua also shows very good results with annual weeds species leaving only 10% weeds density compared to the control. Treatment with these herbicides provides plants with healthy growing conditions for at least three months so that they can be permanently planted in autumn. No phytotoxic signs were apparent for Rosa canina L. seedlings during the whole experiment.
