This paper presents a new complete field mapping of glacial landscapes, landforms and sediments in the Faroe Islands, supplemented by observations from bathymetric maps of the Faroe Shelf. In addition, previous investigations of Quaternary and espe-cially the Weichselian glaciation of the archipelago are reviewed. New cosmogenic nuclide exposure ages indicate that the last extensive glaciation of the Faroe Islands occurred during the Late Weichselian, most likely during the Last Glacial Maximum (LGM; c. 26.5–19.0 cal. ka BP), although a Younger Dryas (c. 12.9–11.7 cal. ka BP) age cannot be entirely excluded. Geomorphological mapping provides a background for reconstructing the extent and type of the glaciation of the Faroe Islands. The reconstructed Weichselian glaciation appears to have had the character of an exten-sive valley glaciation, with several marine glacier termini. The present glaciation of southern Spitsbergen, Svalbard, represents a modern analogue of the reconstructed Weichselian glaciation in the Faroe Islands. The lack of raised coastal features in the Faroe Islands, also at protected sites, suggests that postglacial isostatic uplift was smaller than post-LGM eustatic sea level rise. Numerical glacier reconstructions carried out for different extents of the last extensive Faroese glaciation suggest that such limited postglacial isostatic crustal uplift requires that the Faroe Shelf was not extensively glaciated during the Late Weichselian, but it doubtless was so during at least one of the previous Quaternary glaciations.

Published: February 2023

During their lifespan all the primary equipment installed in power system is subjected to transients. Therefore, it is necessary to adequately dimension and protect the equipment. However, in the networks with high share of renewables, power electronics, cables or near GIS, the failure can occur even though good practice of insulation coordination are fulfilled.

In this paper high frequency power transformer model is presented. Such model is based on measurements of admittance matrix and is adequate for simulation of fast front transient in EMTP like software. Additionally, simulations of lightning and switching overvoltages are given for the observed power transformer unit.

Published: February 2023

The safety of nuclear power plants has always been one of the most important security issues in the industry in general. Numerous standards, techniques, and tools have been developed to deal specifically with the safety of nuclear power plants – one has specialised probes, robotized systems, electronics, and software. Although seen as a mature (or slowly evolving) industry, this notion about nuclear safety is a bit misleading – the area is developing in many promising new directions. Some recent global events will speed up this development even more. On the other hand, the industry is currently going through digital transformation, which brings networking of devices, equipment, computers, and humans. This fourth industrial revolution promises speed, reliability, and efficiencies not possible up until now. In the NDE sector, new production techniques and traditional manufacturing lines are getting to be lights-out operations (near-total automation). The same is most probably going to happen with the safety inspections and quality insurance. Robotics and automation are improving worker safety and reducing human error. The well-being of inspectors working in a hazardous environment is being taken care of. Most experts agree that the digitalization of NDE offers unprecedented opportunities to the world of inspection for infrastructure safety, inspector well-being, and even product design improvements. While the community tends to agree on the value proposition of digital transformation of NDE, it also recognizes the challenges associated with such a major shift in a well-established and regulated sector. The work presented in this paper shows a part of the project that aims to develop a modular ultrasound diagnostic NDE system (consisting of exchangeable transducers, electronics, and acquisition/analysis software algorithms), for applications in hazardous environments within nuclear power plants. The paper will show how the software part of this system can reach near-total automation by implementing various deep learning algorithms as its features and, then, testing those algorithms on laboratory samples, showing encouraging results and promises of online monitoring applications. Furthermore, future general prospects of this technology are discussed, and how this technology can affect the well-being of nuclear power plant inspectors and contribute to overall plant safety.

Published: February 2023

Este ensayo plateó que las analíticas de aprendizaje han mostrado beneficios, pero no todo su potencial, se requiere usar los datos que éstas proporcionan con énfasis en el aprendizaje para una gestión educativa y toma de decisiones efectivas y así avanzar hacia el logro del ODS4 sobre la calidad educativa en las universidades. Una educación de calidad sostenible es un gran reto incluso para países desarrollados y aunque las analíticas se están expandiendo como solución en respuesta a la demanda para retroalimentar el ecosistema educativo, aún existe una gran brecha para aprovechar sus múltiples beneficios. Se discute la aceptación de analítica por el profesorado, ausencia de un modelo de gestión, diferentes motivaciones institucionales para su uso, la falsa dicotomía “objetividad-subjetividad” de los datos, mucha ciencia de datos y poca ciencia de aprendizaje, y paradigmas de enseñanza, como posibles factores a mejorar para lograr el máximo potencial de las analíticas.

Desafíos de una PYME empresa de servicios ante la implementación en NIIF 16-contratos de arrendamiento actualizada al 2019
Authors: Ugalde Herrera Maria Del Pilar
Published: February 2023

Debido a la reciente Pandemia por COVID-19, se incrementaron las modalidades de contrato, algunos en reducción de tiempo laboral, otros en teletrabajo, y suspensión del contrato, asi tambien para los proveedores, servicios o sea leasing y otros. La Junta de Normas Internacionales de Contabilidad (IASB por sus siglas en inglés) emitió una nueva norma contable sobre arrendamientos llamada NIIF 16, la cual rige a partir de 1º de enero de 2019, donde su principal reto es el registro en detallado de cada línea de contrato asi como el  proceso de valoración, medición y reconocimiento, esto  obliga a toda empresa sin excepción mostrar de forma transparente el  registro contable cada uno de los contratos, sea arrendador o arrendatario. asociado a esto la norma de contratos NIC-17 es derogada y la reemplazada por la NIIF-16,que trae implementación de nuevas modalidades de arrendamiento en bienes y servicios, incluyendo  un “activo por derecho de uso”, introduce un único modelo de contabilidad del arrendatario y requiere reconocer activos y pasivos para todos los contratos con duración superior a los 12 meses. Las contrataciones realizadas en Costa Rica para el año 2021 se separan en compras de bienes duraderos, compras de servicios y compras de materiales y suministros, estas últimas adjudicadas en proveeduría mediante el formulario 8F25 Pedimento de materiales y servicio, a lo que resulta que el 87% de las contrataciones corresponde a servicios

Authors:   ”Ion Lupan” Department of pediatric maxillofacial surgery and pediatric dentistry, ”Nicolae Testemitanu” USMF, Institute Mother and Children, Chisinau, Moldova, Railean Silvia
Published: February 2023

Congenital craniofacial deformities in children are conditions with varying degrees of severity between minor and severe, they can be present at birth, but they can also be detected during the child's development. Material and methods. In the period 2014-2021, 57 children (29 boys and 28 girls), average age 9,1 ± 2,4 months, with craniofacial deformities from different medical centers in the Republic of Moldova were examined polysystemically. In this sense, we evaluated the state of the masseter, temporal and tongue muscles by electromyography with surface electrodes to determine the quality of their muscle activity. Recordings of the bioelectrical activity of muscle activity during exercise were performed using a Nihon Kohden portable electromyograph (Japan). Results. The balance dysfunction of the neuromuscular system in these children, as a neuro-physiological sign of pathological muscular weakness in the sucking reflex activity, is highlighted in 87.7% of cases by a marked asymmetry (p<0.001) of the tongue and masseter muscles activity and, respectively less highlighted (p<0.05) of the anterior temporal. Discussion. Thus, the EMG pattern evaluation highlights a decrease in the average amplitude of the action potentials (mV) mainly for the tongue, mm. masseters and temporalis on the left side, associated with an increase in the potential (ms) average duration from both the affected and the contralateral muscles, thus reflecting the reduction in their contraction capacity and the quality decrease in the act of sucking and mastication, predominantly on the left, in the child with congenital craniofacial deformities and disorders of the sucking reflex in infants. Conclusions. The neurophysiological examination highlights various forms of muscle function abnormalities in children with craniofacial deformities, which require multifunctional and multidisciplinary recovery.

Authors: VORONIN MYKOLA
Published: February 2023

The results of a pilot study developed by the author for Ukrainian ATO / OOS veterans in this article are partially presented. 43 veterans were interviewed, including 5 women and 38 men. Among others, the question was asked: "Do you think that going to a psychologist is a shame?" 40 respondents answered that it was not a shame, and three answered that it was a shame. False conclusions can be made that stigma does not bother Ukrainian veterans, but the article shows points that prove otherwise. Conclusion is made that although numbers say that only 3 of 43 respondents mentioned that it was a shame going to psychologist, additional questions revealed stigma concerned veterans among those, who mentioned that it was not a shame.

Authors: PETROCHKO Zhanna
Published: February 2023

The essence of the concept of "child well-being" is revealed as the state of needs satisfaction, rights provision and personal achievement of the person under 18 years. The components of the child's well-being (spiritual-moral, psychic, physical, social) are determined. Indicators of integral well-being of the child (moral and aesthetic education; intellectual mobility; emotional and volitional stability; physical and vital tone; orientation in the world of professions; participation in society and decision-making; comfort; social security; and safety of life) are revealed. The concept of "person's safety", "safety of life activities" are defined. Objective and subjective aspects of security are distinguished. Child safety is grounded in the context of national security. Such security is interpreted in the broad sense, (1) as protection from all forms of physical and psychological violence, abuses, from sexual harassment, peer pressure, intimidation, degrading attitude; (2) as protection from exploitation, drugs, involvement in the worst forms of child labor, armed conflict, etc. Circumstances causing a threat to life and health of the child. Circumstances causing the threat to life and health of the child are listed. Signs that predispose a child's vulnerability (1) age of a child; 2) child's characteristics; 3) state child’s health) are named. Safe behavior of the individual is described. The functional role of well-being states and safety for the harmonious development of a growing personality is revealed. Particular attention is paid to the issue of child safety in the context of social and socio-pedagogical work. An example of a child safety project is presented.
Psychological and pedagogical aspects concerning professional self-determination of student youth
Authors: MORIN Oleg
Published: February 2023

The consideration of the psychological and pedagogical aspects of the professional selfdetermination of students in the field is presented in the context of solving the problem of individual reconciliation of intrapersonal conflicts and social and professional needs. It is noted that the effectiveness of the solution of the problem requires a systematic approach, the pedagogical leadership of this process, the appropriate training of teachers for it, the consideration of the age and individual characteristics of the individual, the consideration of socioeconomic conditions and the main need to enhance the developmental effectiveness of the pedagogical process. This is due to the creation and implementation of qualitatively new methods in educational practice. These methods should be based not on the mechanism of external reinforcement, but on reflexive-willed mechanisms, mechanisms of empathy and positive emotional evaluation, appealing primarily to self-awareness and to theperson's creative attitude to social norms and values. It is noted that the consequence of the development of the individual is the emergence in the individual of a positive motivation for professional self-determination. The creation of an educational system for favorable conditions for thedevelopment of the personality is a mechanism for activating the internal psychological resources of the individual, which in turn will allow thedetermination of certain personal qualities of the individual, namely, the ability to self-realization in a certain professional sphere, actualizing inthe future achieving a significant life goal - trajectory, the construction of a professional career and its implementation. The implementation of the preparation of young people for further independent living in the social environment, the formation of life and professional self-determination, as a result, will determine the effectiveness of the processes of self-change and self-education.

When Journalism Produces Horror Story: The Case of the INSENTIF Podcast by Tirto.id
Authors: Razali Geofakta , Wirawan Wirawan
Published: February 2023

TThis research aims to investigate the production of horror contents in the INSENTIF podcast channel by Tirto.id, an Indonesian online news media. When journalistic media are involved in the production of ghost stories and mystery, it raises concerns about journalistic basic principles of providing verified information. To understand this phenomenon, we conducted a qualitative case study and interviewed three key informants from the INSENTIF production team. Using Giddens’ structuration theory as an analysis framework, we identify that the INSENTIF production crews still perceive their routine as part of journalistic works. In writing the script, they strive to rely on credible sources and actualise the discipline of verification although they admit that they insert some fictional horrific scenarios at the beginning of each episode as well. Thus, they mention a disclaimer, explaining that their journalism practice, specifically on horror episodes, is not the same as the regular Tirto.id’s standard journalism. This research argues that the agents, in this case, seem to follow and reproduce the existing structure, rather than resist it.

A Potential Site for Wide-orbit Giant Planet Formation in the IM Lup Disk
Authors: Bosman Arthur D. , Appelgren Johan , Bergin Edwin A. , Lambrechts Michiel , Johansen Anders
Published: February 2023

The radial transport, or drift, of dust has taken a critical role in giant planet formation theory. However, it has been challenging to identify dust drift pileups in the hard-to-observe inner disk. We find that the IM Lup disk shows evidence that it has been shaped by an episode of dust drift. Using radiative transfer and dust dynamical modeling we study the radial and vertical dust distribution. We find that high dust drift rates exceeding 110 M
⊕ Myr−1 are necessary to explain both the dust and CO observations. Furthermore, the bulk of the large dust present in the inner 20 au needs to be vertically extended, implying high turbulence (α

z
≳ 10−3) and small grains (0.2–1 mm). We suggest that this increased level of particle stirring is consistent with the inner dust-rich disk undergoing turbulence triggered by the vertical shear instability. The conditions in the IM Lup disk imply that giant planet formation through pebble accretion is only effective outside of 20 au. If such an early, high-turbulence inner region is a natural consequence of high dust drift rates, then this has major implications for understanding the formation regions of giant planets including Jupiter and Saturn.
Evolution of the Postmerger Remnants from the Coalescence of Oxygen–Neon and Carbon–Oxygen White Dwarf Pairs
Authors: Wu Chengyuan , Xiong Heran , Lin Jie , Guo Yunlang , Wang Xiaofeng , Han Zhanwen , Wang Bo
Published: February 2023

Although multidimensional simulations have investigated the processes of double white dwarf (WD) mergers, postmerger evolution only focused on the carbon–oxygen (CO) or helium (He) WD merger remnants. In this work, we investigate for the first time the evolution of the remnants stemming from the merger of oxygen–neon (ONe) WDs with CO WDs. Our simulation results indicate that the merger remnants can evolve to hydrogen- and helium-deficient giants with a maximum radius of about 300 R
⊙. Our models show evidence that merger remnants more massive than 1.95 M
⊙ can ignite Ne before significant mass loss ensues, and they thus would become electron-capture supernovae. However, remnants with initial masses less than 1.90 M
⊙ will experience further core contraction and longer evolutionary time before reaching the conditions for Ne burning. Therefore, their fates are more dependent on mass-loss rates due to stellar winds and thus more uncertain. Relatively high mass-loss rates would cause such remnants to end their lives as ONe WDs. Our evolutionary models can naturally explain the observational properties of the double WD merger remnant IRAS 00500+6713 (J005311). As previously suggested in the literature, we propose and justify that J005311 may be the remnant from the coalescence of an ONe WD and a CO WD. We deduce that the final outcome of J005311 would be a massive ONe WD rather than a supernova explosion. Our investigations may be able to provide possible constraints on the wind mass-loss properties of the giants that have CO-dominant envelopes.
Inflammatory Bowel Disease: A focus on the Role of Probiotics in Ulcerative Colitis
Authors: Alzahrani Ashwag , Alzahrani Abdullah Jaman , Shori Amal Bakr
Published: February 2023

Inflammatory bowel disease (IBD) is a cluster of disorders of the gastrointestinal tract characterized by chronic inflammation and imbalance of the gut microbiota in a genetically vulnerable host. Crohn’s disease and ulcerative colitis (UC) are well-known types of IBD, and due to its high prevalence, IBD has attracted the attention of researchers globally. The exact etiology of IBD is still unknown; however, various theories have been proposed to provide some explanatory clues that include gene-environment interactions and dysregulated immune response to the intestinal microbiota. These diseases are manifested by several clinical symptoms that depend on the affected segment of the intestine such as diarrhea, abdominal pain, and rectal bleeding. In this era of personalized medicine, various options are developing starting from improved intestinal microecology, small molecules, exosome therapy, to lastly stem cell transplantation. From another aspect, and in parallel to pharmacological intervention, nutrition, and dietary support have shown effectiveness in IBD management. There is an increasing evidence supporting the benefit of probiotics in the prophylaxis and treatment of IBD. There are several studies that have demonstrated that different probiotics alleviate UC. The present review summarizes the progress in the IBD studies focusing and exploring more on the role of probiotics as a potential adjunct approach in UC management.

Published: February 2023

Brittle stars (class Ophiuroidea) are marine invertebrates comprising approximately 2,100 extant species, and are considered to constitute the most diverse taxon of the phylum Echinodermata. As a non-invasive method for monitoring biodiversity, we developed two new sets of PCR primers for metabarcoding environmental DNA (eDNA) from brittle stars. The new primer sets were designed to amplify 2 short regions of the mitochondrial 16S rRNA gene, comprising a conserved region (111–115 bp, 112 bp on average; named “16SOph1”) and a hyper-variable region (180–195 bp, 185 bp on average; named “16SOph2”) displaying interspecific variation. The performance of the primers was tested using eDNA obtained from two sources: a) rearing water of an 2.5 or 170 L aquarium tanks containing 15 brittle star species and b) from natural seawater collected around Misaki, the Pacific coast of central Japan, at depths ranging from shallow (2 m) to deep (> 200 m) sea. To build a reference library, we obtained 16S rRNA sequences of brittle star specimens collected from around Misaki and from similar depths in Japan, and sequences registered in International Nucleotide Sequence Database Collaboration. As a result of comparison of the obtained eDNA sequences with the reference library 37 (including cryptic species) and 26 brittle star species were detected with certain identities by 16SOph1 and 16SOph2 analyses, respectively. In shallow water, the number of species and reads other than the brittle stars detected with 16SOph1 was less than 10% of the total number. On the other hand, the number of brittle star species and reads detected with 16SOph2 was less than half of the total number, and the number of detected non-brittle star metazoan species ranged from 20 to 46 species across 6 to 8 phyla (only the reads at the “Tank” were less than 0.001%). The number of non-brittle star species and reads at 80 m was less than 10% with both of the primer sets. These findings suggest that 16SOph1 is specific to the brittle star and 16SOph2 is suitable for a variety of marine metazoans. It appears, however, that further optimization of primer sequences would still be necessary to avoid possible PCR dropouts from eDNA extracts. Moreover, a detailed elucidation of the brittle star fauna in the examined area, and the accurate identification of brittle star species in the current DNA databank is required.
Finding the Right Words: Cohesion and Divergence in Inclusive Language Guidelines
Authors: Abbott Miriam
Published: February 2023

Treating patients and colleagues with respect is a foundational value in the healthcare professions. In relating respectful behavior to inclusive communication, several national organizations have recently identified preferred terminology for inclusive language. This article offers a brief background related to inclusive language and describes a comparative textual analysis of several guiding documents (n = 6) from the Centers for Disease Control and Prevention (CDC), the American Medical Association (AMA), and the American Psychological Association (APA). Terms identified as preferred by these organizations were identified and cross-checked through text search software applications. The results and discussion of this analysis compare similarities and differences in key areas. Implications stemming from areas of consensus and variation are explored to develop recommendations for healthcare providers.
Linking Nurses’ Job Embeddedness and Self-Efficacy to Locus of Control
Authors: Gibbs Zelda
Published: February 2023

Locus of control is associated with self-efficacy and job embeddedness which empowers individuals to feel confident in their decisions and engage in organizational activities. This topical review provides evidence for a proposed conceptual model to increase retention of nurses by linking locus of control, self-efficacy and job embeddedness. This approach may facilitate the process of hiring individuals who have an internal drive to be successful. Efforts to train those with an external locus of control to become more internally oriented may be possible and promote retention. Implications of including these concepts in nursing education may improve nursing leader awareness of how self-efficacy and job embeddedness, in association with locus of control, may improve nursing retention.

Bacteriocins produced by lactic acid bacteria are proteinaceous antibacterial metabolites that normally exhibit bactericidal or bacteriostatic activity against genetically closely related bacteria. In this work, the bacteriocinogenic potential of Pediococcus pentosaceus strain ST58, isolated from oral cavity of a healthy volunteer was evaluated. To better understand the biological role of this strain, its technological and safety traits were deeply investigated through a combined approach considering physiological, metabolomic and genomic properties. Three out of 14 colonies generating inhibition zones were confirmed to be bacteriocin producers and, according to repPCR and RAPD-PCR, differentiation assays, and 16S rRNA sequencing it was confirmed to be replicates of the same strain, identified as P. pentosaceus, named ST58. Based on multiple isolation of the same strain (P. pentosaceus ST58) over the 26 weeks in screening process for the potential bacteriocinogenic strains from the oral cavity of the same volunteer, strain ST58 can be considered a persistent component of oral cavity microbiota. Genomic analysis of P. pentosaceus ST58 revealed the presence of operons encoding for bacteriocins pediocin PA-1 and penocin A. The produced bacteriocin(s) inhibited the growth of Listeria monocytogenes, Enterococcus spp. and some Lactobacillus spp. used to determine the activity spectrum. The highest levels of production (6400 AU/ml) were recorded against L. monocytogenes strains after 24 h of incubation and the antimicrobial activity was inhibited after treatment of the cell-free supernatants with proteolytic enzymes. Noteworthy, P. pentosaceus ST58 also presented antifungal activity and key metabolites potentially involved in these properties were identified. Overall, this strain can be of great biotechnological interest towards the development of effective bio-preservation cultures as well as potential health promoting microbes.

Authors: Iqbal Salma , Yaqoob Naveed
Published: February 2023

This paper generically introduces a new notion of trapezoidal linear Diophantine fuzzy numbers in general (TrapLDFNs). We begin by introducing the concept of TrapLDFNs. Then, we propose a ranking method for TrapLDFNs relying on the circumcenter of centroids of TrapLDFN membership and non-membership functions.
On a coupled system under coupled integral boundary conditions involving non-singular differential operator
Authors: Shah Kamal , Abdeljawad Thabet , Abdalla Bahaaeldin
Published: February 2023

In this work, a coupled system under coupled integral boundary conditions with Caputo-Fabrizio derivative (CFD) is considered. We intend to derive some necessary and sufficient results for the existence of at least one solution. In addition, we extend our analysis further to develop a monotone iterative scheme coupled with the upper and lower solution method to compute extremal solutions. Therefore, in this regard, Perov's fixed point theorem is applied to study the existing criteria for the solution. Also, results related to at least one solution are derived by using Schauder's fixed point theorem. Finally, we use a monotone iterative procedure together with upper and lower solution methods to study extremal solutions. Graphical presentations of upper and lower solutions are provided for some examples to illustrate our results.
A mathematical model study on plant root pest management

Published: February 2023

Unlike conventional methods of pests control, introducing in an appropriate mathematical model can contribute a batter performance on pests control with higher efficiency while lest damage to ecosystem. To fill the research gap on plant root pest control, we propose a plant root pest management model with state pulse feedback control. Firstly, the stability of the equilibrium point of the model (1.3) is analyzed by using the linear approximate equation, given that the only positive equilibrium point of model (1.3) is globally asymptotically stable. Moreover, the existence and uniqueness of order 1 periodic solutions of model (1.3) are discussed in detail according to the geometric theory of semi-continuous dynamical systems, successor functions method and the qualitative theory of differential equations. Finally, with further analysis in different methods, the asymptotic stability of the order 1 periodic solution of model (1.3) is obtained by using Similar Poincare Criterion or interval set theorem. The results show that this model can effectively control the number of pests below the economic level of damage.

Published: February 2023

Using Atangana-Baleanu ($ AB $) fractional integral operators, we first establish some fractional Hermite-Hadamard-Mercer inclusions for interval-valued functions in this study. In this, some fresh developments of the Hermite-Hadamard inequality for fractional integral operators are presented. A few instances are also given to support our conclusions. The resulting results could provide new insight into a variety of integral inequalities for fuzzy interval-valued functions, fractional interval-valued functions, and the optimization issues they raise. Finally, matrices-related applications are also shown.

This paper mainly focuses on the dynamics behavior of a three-component chemotaxis system on alopecia areata

   \begin{document}$ \begin{equation*} \left\{ \begin{array}{lll} u_t = \Delta{u}-\chi_1\nabla\cdot(u\nabla{w})+w-\mu_1u^2, &x\in\Omega, t>0, \\ v_t = \Delta{v}-\chi_2\nabla\cdot(v\nabla{w})+w+ruv-\mu_2v^2, &x\in \Omega, t>0, \\ w_t = \Delta{w}+u+v-w, &x\in \Omega, t>0, \\ \frac{\partial{u}}{\partial{\nu}} = \frac{\partial{v}}{\partial{\nu}} = \frac{\partial{w}}{\partial{\nu}} = 0, &x\in \partial \Omega, t>0, \\ u(x, 0) = u_0(x), \ v(x, 0) = v_0(x), \ w(x, 0) = w_0(x), &x\in \Omega, \ \end{array} \right. \end{equation*} $\end{document}

where $ \Omega\subset\mathbb{R}^n $ $ (n \geq 4) $ is a bounded convex domain with smooth boundary $ \partial\Omega $, the parameters $ \chi_i $, $ \mu_i $ $ (i = 1, 2) $, and $ r $ are positive. We show that this system exists a globally bounded classical solution if $ \mu_i\; (i = 1, 2) $ is large enough. This result extends the corresponding results which were obtained by Lou and Tao (JDE, 2021) to the higher-dimensional case.

Published: February 2023

With the help of natural language processing and machine learning, we can analyze the information of online recruitment text posted by employer companies and dig the requirement features of these employment positions, and this is a meaningful work with practical value. However, existing methods for analyzing online recruitment information are too simple to withstand the mass data on the Internet, so this paper aims to study the analysis and forecast of employment position requirements for college students based on big data analysis. At first, the recruitment information of companies is preprocessed, keywords in the recruitment text are extracted by the Term Frequency-Inverse Document Frequency (TF-IDF) algorithm in the Python Chinese word segmentation toolkit, words in the recruitment text are segmented using the open source tool Word2Vec, and the uncounted words in the recruitment text are identified based on the Conditional Random Field (CRF) model. Then, this paper compares the occurrence probability of skills learnt by college students in a certain company employment position with the occurrence probability of the skills in all employment positions on the website, so as to find out the core skills learnt by college students that can match with the job positions required by companies. At last, this paper builds a XGBoost model to forecast the employment position requirements for college students, and verifies the validity of the model using experimental results.
