Tipificación de las faltas y su incidencia en los procedimientos administrativos disciplinarios: el caso de un gobierno local peruano
Authors: Daga-Saravia Rudy Alder , Gonzales-Medina Rosa Karina
Published: October 2024

Esta investigación tiene por objetivo principal determinar en qué medida la tipificación de las faltas afectó los procedimientos administrativos disciplinarios en un gobierno local del Perú en el año 2021. El alcance del estudio se limitó a un muestreo no probabilístico intencional de 35 servidores civiles de la Municipalidad Distrital de Nuevo Imperial. El enfoque de la investigación es cuantitativo; el tipo de investigación que se trabajó fue básica, con nivel explicativo; y, finalmente, a partir de un diseño descriptivo correlacional, se demostró la hipótesis de investigación. A saber, que la tipificación de las faltas incide favorablemente en los procedimientos administrativos disciplinarios, ello con base en la obtención de una correlación positiva débil de r = 0,436, y un valor de significancia bilateral de p = 0,009. La investigación tuvo limitación espacial, debido a que las encuestas se realizaron de manera virtual, en consideración a las normas de convivencia por la pandemia Covid-19; asimismo, es relevante porque no se han realizado investigaciones similares de correlación de las variables: tipificación de las faltas y procedimiento administrativo disciplinario. En la presente investigación se concluyó que la tipificación clara de faltas disciplinarias tiene un impacto significativo en los procedimientos administrativos disciplinarios de la Municipalidad Distrital de Nuevo Imperial durante el año 2021. Los hallazgos respaldan la importancia de establecer normas claras y consistentes en la tipificación de faltas disciplinarias para promover la eficacia, la justicia y la transparencia en los procesos disciplinarios dentro de las instituciones gubernamentales. Sin embargo, se reconoce la complejidad inherente al comportamiento humano y la necesidad de abordar múltiples dimensiones para mejorar la conducta y el desempeño ético de los servidores públicos.

: As formas híbridas de ensino foram impulsionadas pelas necessidades emergenciais associadas à pandemia de Covid-19. Dessa maneira, a convergência de mídias nos processos de aprendizagem e de ensino tem sido cada vez mais enaltecida. Esta pesquisa buscou analisar os vídeos mais relevantes distribuídos pelo YouTube que discutem as simulações interativas do projeto PhET para o ensino de química. Foram analisados 23 videoaulas, nos idiomas português e inglês, segundo os critérios estabelecidos pela Teoria Cognitiva de Aprendizagem Multimídia (TCAM). Neste artigo, focamos a apresentação dos resultados em relação ao processamento gerativo da TCAM. Entre os principais resultados, constatou-se a exploração parcial de técnicas de personificação - como filmagem em primeira pessoa ou uso de gestos por parte do apresentador - e a ausência de propostas de atividades gerativas. Nesse sentido, na conclusão do estudo, indica-se que em novos vídeos se busque apresentar atividades dirigidas que envolvam a participação ativa do aprendiz.

Introduction. Epidermal growth factor receptor (EGFR) is a transmembrane protein of the receptor tyrosine kinase family that is activated in various cancers (non-small cell lung cancer, colorectal cancer, head and neck tumors). In glial brain tumors, increased EGFR expression levels are characteristic of the most aggressive subtype, glioblastoma. Frequent structural changes of EGFR in glioblastoma are amplification of the chromosome region where the EGFR gene is located, point mutations, as well as deletion of exons 2–7 of the EGFR gene leading to the formation of EGFRvIII transcript.Aim. To determine structural changes of the EGFR gene (point mutations and amplification of the EGFR gene, EGFRvIII transcript) in tumor samples using different methods and to evaluate their potential clinical significance.Materials and methods. The study included 75 patients with brain gliomas (70 of them glioblastoma) aged 34 to 78 years (mean age 56 years). DNA and RNA isolation was performed from fresh frozen tumor tissue, as well as from peripheral blood leukocytes. EGFR gene mutations were determined by next-generation sequencing (NGS), and β allele frequency (BAF) comparative analysis (normal-tumor) was performed to determine the copy number of chromosome 7 regions. Quantitative polymerase chain reaction was used to confirm the EGFR gene amplification in tumor samples, and reverse transcription-PCR was used to detect EGFRvIII variant.Results. The NGS method revealed 11/70 (16 %) mutations in coding regions of EGFR gene in glioblastoma samples, the EGFR gene amplification was detected in 26/70 (37 %) cases; no structural changes of the EGFR gene were detected in 5 glioma samples (astrocytoma, oligodendroglioma). All cases of EGFR gene amplification detected by NGS were confirmed by quantitative polymerase chain reaction. To search for EGFRvIII transcript, 31 tumor RNA samples were examined, of which EGFR amplification was present in 12 samples. EGFRvIII transcript was detected only in samples with EGFR gene amplification – 4/12 (33 %). To assess the clinical significance of structural gene alterations, the frequency of occurrence in primary and recurrent glioblastoma samples was compared.Conclusion. The NGS method allows to detect both point mutations and amplification of the EGFR gene. The EGFR gene amplification was associated with EGFRvIII mutation in 33 % of cases. No statistically significant differences in the frequency of structural changes in the EGFR gene between primary and relapsed glioblastomas were found.

Published: October 2024

The spectral graph theory is concerned with the relationship between the spectra of specific matrices associated with a graph and the structural properties of that graph. This paper introduces a general symmetric degree adjacency of a graph G, general symmetric degree of a graph G, and complete weighted graph of a graph. Here we explore its characteristic polynomial using Sachs theorem. We also investigate the bounds for index and energy of general symmetric degree adjacency of a graph. We give two algorithms, first one to find general symmetric degree adjacency of a graph G and second one to find general symmetric degree of a graph G.
On properties of the Hasse diagrams of NP-critical posets of order less than 8
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Stopochkina Maryna
Published: October 2024

M. Kleiner proved that a poset has finite representation type if and only if it does not contain subposets of the form (1, 1, 1, 1) =, (2, 2, 2) =, (1, 3, 3) =, (1, 2, 5) = and (И, 4) =, which are called the critical posets. A generalization of this criterion to the tame case was obtained by L. O. Nazarova. The corresponding posets are called supercritical and consist of the posets (1, 1, 1, 1, 1) =, (1, 1, 1, 2) =, (2, 2, 3) =, (1, 3, 4) =, (1, 2, 6) = and (И, 5) =. The critical and supercritical posets are also (respectively) critical respect to weakly positivity and weakly non-negativity of the Tits quadratic form which is given by the equality. In the case of substitution on positivity and nonnegativity, such posets which are called P-critical and NP-critical, respectively, were described by the author together with V. M. Bondarenko (their number, up to isomorphism and duality, is 75 and 115). This article studies combinatorial properties of the Hasse diagrams of NP-critical posets.
The Impact of Standing Waves on Localization Ability of Low-Frequency Sound Sources
Authors: Năstasă Mădălina , Pulkki Ville , Mäkivirta Aki
Published: October 2024

This paper studies the effect of room modal resonances on the localization of very low–frequency sound sources. A subjective listening test is conducted with 20 participants in an anechoic chamber, where the listener must detect the direction of the sound source for pure sinusoids at 31.5, 50, and 80 Hz. A synthetic standing wave pattern modeling a room resonant effect is created with two additional sound sources located at the left and right sides of the listener. Results show that the perception of low-frequency direction is negatively impacted by the node of the standing wave, even when the standing wave has a relatively low level, whereas the antinode does not have as strong of an effect. The second experiment conducted indicates that variations in the presentation level does not impact the effect of the standing wave. The results of this study suggest that in the low-frequency spectrum, direction judgement is not so strongly a question of this auditory system’s ability but more so of the acoustical properties of the listening environment.
Active Acoustics with a Phase Cancelling Modal Reverberator
Authors: De Bortoli Gian Marco , Prawda Karolina , Schlecht Sebastian J.
Published: October 2024

Active acoustics (AA) systems are used to electronically modify the acoustics of a room (e.g., in live music venues). AA systems have an inherent feedback component and can suffer from instability and coloration artifacts resulting from too high feedback gains. State-of-the-art methods can improve system stability and coloration, usually at the cost of complex implementations and long parameter-tuning sessions. They can also cause sound artifacts due to time-varying components, limiting the enhancement at low frequencies. This work proposes a time-invariant feedback attenuation method for low frequencies based on a modal reverberator. The attenuation is achieved through destructive acoustic interference, obtained via phase shifts between the input and output signals. The analyzed frequency range is 0–500 Hz, where the room transfer functions are considered highly invariant over time. The results show a gain-before-instability increase of more than 5 dB for a modal reverberator with high mode density in this frequency range. The improvement is also stable for low-magnitude changes in the room transfer functions over time. The proposed method provides a robust AA system with artificial reverberation for the low-frequency range and can be used alongside other established methods.
A Perspective on the Rupture States of Complex Earthquake Scenarios in the 2023 USGS Seismicity Model for the Western U.S. Faults
Authors: Mahdyiar Mehrdad
Published: October 2024

The 2023 U.S. Geological Survey (USGS) seismicity model for faults in the western United States (USGS-SMF-WUS) includes many earthquake scenarios (EQS) that rupture multifault sections (MFS), reflecting decades of observations that large crustal earthquakes often rupture sections of different neighboring faults in complex ways. Many of the complex MFS scenarios include rupture sections, on different faults, that are not contiguous, with spacing up to 15 km. The USGS-SMF-WUS uses an inversion methodology, referred to as magnitude-rate optimization, to optimally formulate the occurrence rates of the EQS in such a way that they collectively release the accumulating seismic moment rates on faults, at subsection level, defined by various types of geologic, geodetic, and seismologic data and constraints. This raises questions about the treatment of the MFS scenarios in the USGS-SMF-WUS regarding their rupture states and how that could potentially impact the magnitude-rate optimization and ground motions (GMs) for hazard analysis. Among many different possible rupture states for the MFS earthquakes, the two extreme scenarios could be visualized as (1) a series of noncontiguous sections rupturing in such a way that their total seismic moment and GM footprints are scaled with the sum of their rupture areas and (2) a series of noncontiguous triggered events, grouped together based on the spacing between the participating fault sections and other criteria, each releasing seismic moment and generating GM footprints that are scaled with its own rupture area. It will be shown later that the average slips on the participating sections for these two extreme rupture states would not be the same. In addition, the GM footprints from these two rupture states would be different and the differences are frequency dependent. This is especially the case when considering the complexity of rupture directivity on the participating fault sections in the USGS-SMF-WUS. It is the objective of this study to explore and discuss the implications of the triggered rupture state assumption in estimating the average slips and GM footprints of the MFS earthquakes in the USGS-SMF-WUS.
The Antibiotic Sensing Mechanism of VanS from Type-B Vancomycin-Resistant Enterococci
Authors:   , Rotsides Photis S. , Loll Patrick J.
Published: October 2024

Vancomycin-resistant Enterococci (VRE) are able to sense the presence of vancomycin and subsequently activate resistance against the antibiotic. This activation mechanism is regulated by VanS, a membrane-bound sensor histidine kinase. In the presence of vancomycin, VanS initiates a signaling cascade that leads to the expression of resistance genes in VRE. However, the molecular details of how VanS senses vancomycin remain a mystery. Vancomycin sensing could involve direct binding to the antibiotic, whether by VanS or adaptor proteins that transmit the signal to VanS. Thus, identification of vancomycin-binding proteins will unravel the mechanisms by which VRE sense the antibiotic. To this end, we created diazirine-based photoprobes that specifically label known vancomycin-binding proteins. We also developed an anti-vancomycin antibody, allowing for the direct detection of photolabeled protein without the need for a reporter tag. Using these photoprobes and solution-based assays, we demonstrated that vancomycin directly binds to the periplasmic sensor domain of VanS from type-B VRE (VanSB). Computational models and HDX-MS results indicate that the VanSB sensor adopts a PAS-like fold. An extensive buffer screen was implemented to find conditions that stabilize the VanSB sensor, allowing for structural studies by NMR. Together, this work demonstrates that VanSB directly binds to vancomycin to activate resistance in type-B VRE. Also, our novel photoprobes will be useful tools for elucidating vancomycin-sensing mechanisms in other pathogens.

Published: October 2024

Nanotechnology has positively impacted the development of extenders used in the cryopreservation of spermatozoa in livestock. The inclusion of nano skim in the extender is expected to preserve semen quality after thawing. This study aimed to determine the optimal concentration of nano skim. Various concentrations of nano skim (0%, 1.66%, 3.33%, 5%, 6.66%, 8.33%, and 10%) with the addition of 10% nano egg yolk in each extender were compared. Fresh semen samples were collected from three three-year-old Simmental bulls using an artificial vagina. The study parameters included motility (total motility, progressive motility) and kinematics (velocity curve linear (VCL), velocity straight linear (VSL), velocity average pathway (VAP), amplitude lateral head (ALH), beat cross frequency (BCF), straightness (STR), linearity (LIN), and wobble (WOB). A completely randomized design was employed, and data were analyzed using analysis of variance (ANOVA). Fresh semen dilution results indicated that only the control group (0%) and the nano skim group with concentrations of 6.66% and 8.33% were eligible for further processing into frozen semen. The results showed no significant difference between the three treatment groups on sperm motility and kinematics of Simmental cattle after thawing (p0.05). The control group exhibited the highest percentage of total motility, VCL, VAP, and ALH values, while the 6.66% nano skim group outperformed the 8.33% nano skim group. The highest percentage of progressive motility and VSL value was observed in the 6.66% nano-skim group compared to the 8.33% nano-skim and control groups. The highest values of BCF, WOB, LIN, and STR was observed in the nano-skim group at 8.33% compared to the nano-skim group at 6.66% and control. The study concluded that 6.66% nano skim was the optimal concentration to maintain the quality of frozen semen of Simmental cattle.

Published: October 2024

This study aimed to compare the meat quality of different beef cattle breeds using ultrasound imaging. A total of 28 cattle, aged 1-2.5 years, from three breeds were analyzed: Wagyu (n=7), Bali (n=10), and Wagyu×Bali cross-breeds (n=11). Meat quality traits, including longissimus dorsi thickness (LDT), backfat thickness (BFT), intramuscular fat (IMF), and marbling score (MS), were assessed using ultrasound imaging. The association between breed and meat quality was analyzed using a completely randomized design (CRD) followed by Tukey's test. Additionally, principal component analysis (PCA) was employed to identify clusters of meat quality potential among the different breeds. The results indicated that Wagyu×Bali cross-breeds exhibited the highest LDT (46.380±4.770 mm), though the difference was not statistically significant (P≥0.05) compared to either Bali or Wagyu cattle. However, significant differences (P≤0.05) were observed between Bali and Wagyu cattle. For BFT, MS, and IMF, Wagyu cattle outperformed both Bali cattle and Wagyu×Bali cross-breeds, with values of 5.490±0.806 mm, 6.010±0.998, and 49.05±8.140%, respectively. The PCA revealed two primary clusters: the first cluster, comprising Wagyu cattle, accounted for 75.6% of the diversity and was characterized by BFT, IMF, and MS as key variables. The second cluster included Bali cattle and Wagyu×Bali cross-breeds, representing 21.5% of the diversity, without any specific meat quality variable as a defining marker. Ultrasound imaging effectively estimated meat quality in Bali cattle and their cross-breeds, demonstrating its potential as a tool for meat quality assessment across different breeds.

Published: October 2024

Pre-weaning growth is crucial for achieving high weaning weights, which are expected to positively correlate with the overall performance of does/ewes. Milk replacer, designed to meet the nutritional needs of pre-weaning kids, offers a solution to this challenge. This study aimed to analyze and evaluate the impact of incorporating maggot flour into milk replacer on the performance of pre-weaned Peranakan Etawa (PE) crossbreed goats. The parameters observed included milk replacer intake, nutrient consumption, body weight gain, weaning weight, rectal temperature, respiratory rate, and feed cost per gain. The study involved 10 two-week-old local pre-weaned PE goats, each with an average body weight of 5.33 ± 0.93 kg, divided into two treatment groups with five replicates each. The treatments included a commercial milk replacer (P0) and a milk replacer containing maggot flour (P1). Data were analyzed using an independent t-test at a 5% significance level. The results showed that daily body weight gain in pre-weaned PE goats fed milk replacer containing maggot flour did not differ significantly (P0.05) from those fed the commercial milk replacer. The physiological responses of the pre-weaned goats, including rectal temperature and respiratory rate, were similar between treatments and did not negatively affect their physiological status. The lowest feed cost per gain was observed in the group fed the maggot flour-based milk replacer (P1), indicating its potential economic advantage.

Published: October 2024

This study aimed to improve the quality of KUB chicken eggs and meat through dietary supplementation. Fifty KUB chickens, aged three months, were reared for three months. The treatments were as follows: P0 (control) = basal ration (BR), P1 = BR + 0.4 g/head/day turmeric flour, P2 = BR + 0.4 g/head/day turmeric powder + 1 black pepper capsule (0.2 g/head/day), P3 = BR + 0.4 g/head/day turmeric flour + 2 black pepper capsules (0.4 g/head/day), and P4 = BR + 0.4 g/head/day turmeric flour + 3 black pepper capsules (0.6 g/head/day). Parameters measured included the digestive tract profile, lactic acid bacteria (LAB) count in the cecum, egg quality, egg cholesterol, and unsaturated fatty acid content in meat. Results indicated that while most treatments did not affect the relative weight and length of the small intestine, P1 significantly increased the relative weight of the duodenum by 57.4% compared to the control. P1 also improved LAB counts and egg quality. P2 reduced egg cholesterol by 27.1%, and P4 increased unsaturated fatty acid content in meat by 14.4% over the control. These findings suggest that turmeric powder and black pepper supplementation can enhance egg and meat quality as well as the overall performance of KUB chickens.

Published: October 2024

Kaur cattle, a local breed in Bengkulu, represent a valuable genetic resource that requires preservation and effective utilization to enhance livestock production. Turmeric, curcuma, and ginger are plants known for their essential oils and curcumin content, which offer numerous proven benefits. This study aimed to evaluate the impact of these feed additives on the productivity of Kaur cattle. A quantitative research method employing a completely randomized design was used, consisting of four treatments and four replications. The diet comprised wild grass (10% of body weight) and palm kernel meal in an 80:20 ratio. The treatments were as follows: P0 (control: wild grass and palm kernel meal), P1 (wild grass, palm kernel meal, and turmeric powder Curcuma xanthorrhiza Roxb.), P2 (wild grass, palm kernel meal, and curcuma powder Curcuma longa L.), and P3 (wild grass, palm kernel meal, and ginger powder Zingiber officinale Rosc.). The study involved 16 male Kaur cattle aged 1.5-2 years, with an average body weight of 160-180 kg, observed over 60 days. The variables measured included average daily weight gain, forage consumption, total feed consumption, feed efficiency, and cost efficiency. Data were analyzed using a one-way ANOVA. The results showed that the mean daily weight gain (kg/head/day) was P0=0.35±2.57, P1=0.47±2.39, P2=0.50±2.46, and P3=0.49±2.88, with no significant differences between treatments. The mean feed efficiency (%) was P0=0.12±4.44, P1=0.25±4.71, P2=0.27±5.22, and P3=0.26±4.38, also showing no significant differences. The mean cost efficiency for feed use was P0=35,869±7.47, P1=34,281±7.08, P2=33,220±7.39, and P3=35,410±7.21, with no significant differences observed. Overall, the addition of turmeric, curcuma, and ginger powders to the feed did not significantly impact the productivity of Kaur cattle.

Published: October 2024

This study aimed to evaluate the quality of Total Mixed Ration (TMR) pellets derived from agricultural waste and assess their potential as feed for Rex rabbits. The research employed an experimental approach, utilizing agricultural and plantation waste to produce TMR pellets. The study was conducted in two stages: pellet production and rabbit feeding trials. Three formulations of TMR pellets were developed with varying concentrations of oil palm empty fruit bunches (EFB): P1 (5% EFB), P2 (10% EFB), and P3 (15% EFB). The optimal formulation was subsequently used for the feeding trials. Rabbit feed treatments included T0 (60% commercial pellet + 40% forage), T1 (40% commercial pellet + 20% TMR pellet + 40% forage), T2 (30% commercial pellet + 30% TMR pellet + 40% forage), and T3 (60% TMR pellet + 40% forage). Results from the pellet analysis indicated no significant differences in organoleptic properties among the formulations. The durability test yielded the highest value of 98.77%, while the proximate analysis of the P1 formulation showed a dry matter content of 85.67%, ash content of 10.35%, organic matter of 89.65%, crude protein of 18.65%, crude fat of 18.72%, and crude fiber of 19.18%. In the rabbit feeding trials, there were no significant differences in rabbit performance when compared to those fed with commercial pellets. Based on these findings, it can be concluded that agricultural waste can be effectively utilized as a raw material for rabbit feed pellets, offering comparable quality to commercial alternatives. This research highlights the potential of agricultural waste in reducing environmental pollution while providing an economically viable alternative for animal feed.

El abuso en la utilización de vínculos temporales en las Administraciones Públicas españolas es una lacra histórica. Los diversos intentos de atajar esta situación se han demostrado hasta el momento inútiles, pero se reiteran sistemas previos de estabilización con la Ley 20/2021, y ello pese a que persisten las dudas legales sobre su acomodo al Acuerdo Marco. Diversas cuestiones prejudiciales planteadas van a obligar al Tribunal de Justicia a decidir sobre la legalidad de la norma y sobre el sistema de empleo del personal público español.
Building Up Local Productivity: Infrastructure and Firm Dynamics in Mexico
Authors: Busso Matías , Fentanes Oscar
Published: October 2024

What determines the aggregate and distributional effects of new transportation infrastructure? One key overlooked channel is the role that infrastructure policy plays in changing the incentives of firms to enter, exit, and grow--in turn generating endogenous changes in local productivity. In this paper, we document and quantify the importance of this channel by using detailed Mexican microdata and a spatial general-equilibrium model that incorporates firm dynamics. Leveraging random delays in the construction of highways, we empirically show that productivity grows in places with better transportation infrastructure. Firms play a critical role in driving these results: highways increase firms' size, entry rates, survival rates, and total factor productivity. Then, by calibrating our model on census data between 1998 and 2018, we find that new highways over this period increased welfare and income by half a percent, similar to its costs in terms of GDP. Moreover, we find substantial spatial reallocation of workers and production. Nearly half of these effects are explained by endogenous changes in local productivity, which is driven by firm dynamics.

El presente estudio evaluó los efectos del uso de herramientas digitales basadas en una aplicación de realidad aumentada, denominada Geometría RA, en estudiantes de séptimo grado de la sede C de la Institución Educativa Técnico Dámaso Zapata. Adicionalmente, se buscó justificar una estrategia pedagógica que coadyuve en el razonamiento e interpretación de situaciones problema basadas en la modelación de figuras tridimensionales asistida por realidad aumentada (RA). Es así que se aplicó el estudio en dos grupos: uno experimental y uno de control, en donde el primero de ellos usó una aplicación de RA en sus dispositivos electrónicos, mientras que el grupo de control fue expuesto a una enseñanza tradicional. Al inicio y final del experimento, ambos grupos fueron evaluados a través de una prueba escrita consistente en un Pre Test-Post Test y una encuesta que validaron la implementación de la propuesta. Los resultados sugieren que el uso de la realidad aumentada en los procesos de enseñanza-aprendizaje tiene efectos en el fortalecimiento de las competencias interpretativas, especialmente en aspectos de reconocimiento de elementos ocultos como las líneas notables en sólidos de revolución, especialmente en el cálculo de sus áreas y volúmenes. Lo anterior redunda en un mejor razonamiento de situaciones problema en geometría, el mejoramiento de los procesos de análisis y la incidencia de ella en el cambio de actitud hacia nuevas técnicas de aprendizaje.
Grammatical systematicity of request models in the modern Russian
Authors: Karpenko L. B. , Liu Xiaoxia
Published: October 2024

The article analyzes the grammatical systematicity of models of request expression in modern Russian language. The relevance is determined by the need to identify the grammatical systematicity of the use of syntactic models of different types in expressing a request in Russian speech practice. The aim of the paper is to study syntactic models of request expression in modern Russian language in the aspect of the theory of communicative-pragmatic complexes. The study is conducted on the material representing different contexts of request usage: samples from modern Russian plays by famous playwrighters – A. Vampilov, N. Lakutin, E. Shabalina and A. Yablonskaya, as well as samples from the National Corpus of the Russian Language (NCLR) are used. Research methods: systematic, comparative, functional, contextual, structural-grammatical. Special attention is paid to the phenomenon of systematicity of syntactic models. The peculiarity of expressing the request by the models of sentences on the purpose of utterance – inductive, interrogative and narrative – is shown. The authors come to the conclusion about the peculiarity of linguistic conceptualization of request in three communicative situations – everyday request, official request, request when communicating in an unfamiliar environment, which differ in their communicative role and situations of use. The regularities of use of three types of sentences on the purpose of utterance depending on communicative situations are established. It is shown that the model of inductive sentences serves as the basic and most common grammatical form of expressing a request and is usually used in the communicative situation of a household request. Due to its special communicative characteristics, this model can also be used in the situation of communication with strangers, and with the use of grammatical extensions - and in some situations of official communication. The second most frequent type - interrogative sentences - is usually used when addressing strangers; as a rule, it is accompanied by politeness markers. Models of narrative sentences are used much less frequently than sentences of the other two types; they are most often used in situations of official communication.
«Confrontation of fonts: Gothic vs Antiqua» in the language politics of the Third Reich
Authors: Dubinin S. I.
Published: October 2024

The article is devoted to the consideration of the script in the modern history of the German literary language, associated with the design of its normative graphics (graphemics), in particular the «font dispute: antiqua vs gothic» in the first half of the 20th century. For a significant period of historical development, the German literary language is marked by «cognitive dissonance» caused in the linguistic consciousness of its speakers by the collision of «conflicting» variants of Latin characters. The parallel use of various graphic variants of writing (diglyph), especially at the stage of the modern history of the German language, is marked by the influence of various extra-linguistic factors (ideology, confessional, cultural differences, national and state policies, etc.). A pressing issue is the consideration of the radical and controversial language policy in the totalitarian Third Reich in 1933–1945. Declaring Fraktur as a «national script», a symbol of identity and the embodiment of basic doctrines (unity of the nation and German-speaking ethnic groups, anti-Semitism, «struggle for culture», the idea of superiority), the National Socialists in 1941, at the stage of reorienting their policy towards «Eurocentrism», declared it replacement of the previously rejected antiqua as «normative German writing». The article provides a critical stage-by-stage analysis of the scenarios of the language policy of National Socialism in the «dispute about graphics», attempts to use a «compromise font» (Futura). Ideologemes associated with this practice are analyzed as lexical markers (Sprachregelung, Kulturkampf, Schrifttum, Judenlettern, deutsche Volksschrift/Normalschrift, etc.). The result of the study was the construction of a model of «font strategy» as a special linguistic-semiotic phenomenon of the language policy of the Third Reich. The conclusions note a peculiar reflection of the «font dispute» in different types of texts of 1933–1945 and in the military discourse of the Third Reich.
Role of dysphemisms in the English-language film space
Authors: Antsiferova A. N.
Published: October 2024

The topicality of undertaken research is determined by the constantly changing social norms in modern society, which are reflected in the cinematographic world. Cinematography provides a golden opportunity to consider and analyze a range of unique linguistic phenomena. The major purpose of the present paper is to study the phenomenon of dysphemisation in the English-speaking film space based on the set of the following films in English: Green Book by the American film director, Peter J. Farrelly, the screen adaptation of the autobiography 12 Years a Slave by Terrence S. McQueen, the well-known film The Help by Tate Taylor and the biographical drama Hidden Figures by Theodore Melfi. In the films the main storyline is generally based on the aspect of discrimination against persons of certain racial backgrounds and women, based on the policy of the United States of America during the infamous period of slavery (XVII–XIX centuries) and the historical era of segregation (XIX–XX centuries). During the study theoretical methods (analysis and synthesis) and empirical methods (observation and description) were used. As a result of the conducted study, the classification of dysphemistic lexical units was determined in terms of author’s intentions (dysphemisms with an emphasis on a different skin color; dysphemisms-comparisons with animals, plants and inanimate objects; dysphemisms-designations of social status; dysphemisms expressing gender discrimination), as well as their role and reason for use in the selected set of films – demonstration of a biased, cruel attitude towards recipients and also a reflection of the socio-cultural environment that encompassed US society during the historical time period under study.
Intonation cues to English public discourse perception
Authors: Mitrofanova Yе. N.
Published: October 2024

The study considers the discourse functions of intonation and identifies a few problems and contradictions in the current theories of intonation functioning. Particular attention is paid to such issues as the multiple functions of nuclear tones, pitch declination in utterances and perceptual identification of spoken paragraphs. An attempt has been made to handle these problems in the context of English public speeches delivered in the format of TED talks. The purpose of the auditory analysis of discourse intonation in these talks is to check the perceptual reliability of intonation cues in processing spoken discourse and the possibility of using intonation as an on-line perception strategy. The methods applied in the research are descriptive, auditory and comparative, supported by a certain amount of quantitative data. The results obtained in the auditory analysis show that intonation cues work most effectively at the level of intonation groups and utterances but are not self-sufficient in paragraph identification. The leading function of nuclear tones in public discourse organization turns out to be the information structuring of utterances, which is occasionally interrupted by the attitudinal function. Pitch declination has been found to be one of the most important cues to the integrity and cohesion of utterances, with an average length of three-four intonation groups. Multiple declinations in spoken utterances are infrequent and are triggered by particular types of syntactic relations in elongated sentences. The study contributes to the linguistic description of discourse intonation, and its results can be beneficial for language teaching practice and automated speech synthesis.

This review is devoted to the monograph «Lexical metonymy in linguistic and cognitive comprehension» by N.A. Ilyukhina, who examines the problems of using metonymic nomination of objects, processes and persons in various denotative and discursive spheres. The relevance of the issues raised in the monograph is determined by the important role of associative thinking in the process of understanding the reality and complexity of mental connections between referents, which become the objects of metonymic nomination. The review describes the issues that have become the focus of the researcher’s attention, in particular, the typologization of lexical metonymy, substantive and verbal metonymy, metonymic transfer of definitions, metonymy in various denotative and discursive spheres. The problem of the research lies in the complexity of the linguistic representation of the cognitive mechanisms of metonymic transfer, in understanding the mental connections between the part and the whole, due to which their names can replace each other in language and speech. During the research N.A. Ilyukhina used an up-to-date method of linguocognitive analysis. As a result of the conducted fundamental research, N.A. Ilyukhina comes to a number of important conclusions. The most significant and interesting conclusions are about the unified cognitive foundations of the main transfers in the system of language and speech; about the connection of the transfer vector with the structural type of a multi-faceted concept, which contains knowledge about the corresponding referent, nominated or defined by the word; about the most significant role of the cognitive metonymic mechanism in speech activity; about the «ubiquity», universality, versatility and expansion of linguistic metonymy due to its cognitive foundations; about the possibility of using metonymy as a basis for other tropes. The monograph is of considerable interest to researchers dealing with the problems of metonymy, cognitive linguistics, semasiology, and semantics of discourse.
