Forecasting Employees’ Promotion Based on Personal Indicators by Using a Machine Learning Algorithm
Authors: Ibrir Yasmine Aya , Çavur Mahmut
Published: October 2024

Promotion is a tool to motivate employees to improve themselves and take on the burden and responsibility of the position assigned to them. Due to the fairness and measurability of promotions conducted by traditional methods needing to be quantifiable, different methods are required. In recent years, with the widespread use of information systems in companies, much information, such as performance data of employees, has started to be stored digitally. Additionally, with the development of data sciences and their application in many fields, machine learning and artificial intelligence algorithms in evaluating this data have become widespread. This study aims to establish a robust framework to predict employee promotions based on various features. These features include but are not limited to the number of training sessions attended, previous year ratings, tenure, awards received, and average training scores. The study aims to provide organizations with a reliable tool to make informed promotion decisions and demonstrate that this framework can be generalized to other prediction problems. Experimental results show that the XGBoost model is the most efficient in terms of accuracy. XGBoost is considered a superior algorithm with 94% accuracy, 94% ROC AUC, 94% sensitivity, and 94% precision, excelling in memory usage efficiency, accuracy, and runtime.

Global biodiversity continues to decline in the terrestrial and aquatic realms. Across animal groups, threatened species are at risk of extinction if not managed effectively and permitted to recover. The cartilaginous fish order Rhinopristiformes (rhino rays) comprises 5 families: sawfishes, wedgefishes, guitarfishes, giant guitarfishes, and banjo rays. While the global plight of sawfishes, which are heavily depleted and have undergone range contraction unprecedented in cartilaginous fishes, has drawn attention to their status, the other families have received less focus to date. To highlight research on the non-sawfish rhino rays, the American Elasmobranch Society held the inaugural Global Wedgefish & Guitarfish Symposium in 2021. This Special Issue of Endangered Species Research presents a series of papers from that symposium. Rhino rays (68 species globally) face an extremely elevated risk of extinction, with nearly three-quarters of species threatened (72.7%; Critically Endangered, Endangered, or Vulnerable on the IUCN Red List of Threatened Species) and nearly half (48.5%) of all species classified as Critically Endangered. This level of critical endangerment is amongst the highest of all 136 vertebrate orders, with rhino rays ranking only below sturgeons and paddlefishes (order Acipenseriformes) and coelacanths (Coelacanthiformes). Recommendations for research priorities were developed through an expert-elicitation approach in the fields of status, taxonomy, life history, habitat, molecular ecology, fisheries, trade, and ex situ breeding. Only significant investment in research priorities will strengthen the information base upon which to make conservation and management decisions and secure a future without extinctions for rhino rays.
Fine-scale behaviour and population estimates of endangered sooty albatross suggest low exposure (while not excluding high sensitivity) to bycatch

Published: October 2024

Recent developments in assessing species-specific seabird bycatch risks have demonstrated that fine-scale approaches are essential tools to quantify interactions with fishing vessels and to understand attraction and attendance behaviours. Matching boat movement with bird tracking data specifically allows us to investigate seabird-fisheries interactions for cryptic species for which on-board information is critically lacking. The sooty albatross Phoebetria fusca overlaps with fisheries throughout its range and is known to be vulnerable to incidental bycatch. Combining radar detectors, GPS and behavioural data from individuals from the Crozet Islands and boat locations during the incubation period, we investigated interactions of sooty albatrosses with fisheries in the southern Indian Ocean. Individuals foraged mostly in sub-tropical international waters, where they only encountered a small number of boats, all reporting to the Automatic Identification System (AIS). The low interaction rate during this period may suggest that sooty albatrosses are not strongly attracted to fishing vessels, and that attraction rates may vary between populations. However, this result should be interpreted with caution due to the low sample size and fishing effort during the study period, as these observations may conceal a higher bycatch risk during intense fishing effort and/or energetically demanding periods. The conservation status of this species requires further data to be collected throughout the annual cycle to provide an accurate assessment of the threat.
Variation in coral rubble cryptofauna is scale-dependent and driven by small-scale habitat characteristics

Published: October 2024

Motile cryptofauna living in dead coral rubble represent some of the greatest biodiversity and basal energetic resources on tropical coral reefs. Yet we know relatively little about how and why coral rubble cryptofauna communities change over space and time. As human impacts increase the degradation of living hard corals to dead coral rubble on many reefs worldwide, understanding the communities that will succeed in these degraded environments and the factors paramount to their success becomes increasingly central to coral reef ecology and conservation. Using a remote and uninhabited oceanic atoll in the Pacific Ocean, we quantified the natural spatial variability in motile cryptofauna diversity and community structure in coral rubble across scales (m to km) and tested whether variability at smaller scales could be explained by gradients in microhabitat. We show that coral rubble cryptofauna communities are most variable at intra-site scales (m) rather than inter-site scales (100s m) or between reef zones (km scales). We also show that a substantial amount of variation in cryptofauna density (55%) and phyla-level community structure (31%) is explained by small-scale habitat characteristics, specifically the substrate type below the rubble and the variability in macroalgal cover on individual rubble pieces. Our findings highlight the need to study small-scale processes that are relevant to motile cryptofauna and their community interactions if we are to elucidate the structuring forces of these diverse cryptic assemblages on coral reefs.

THE EFFECT OF THE COLOR AND CHARGE SOURCE OF THE LUMINESCENT PIGMENT ON THE PROPERTIES OF LUMINOUS CONCRETES
Authors: Kravchenko D. , Suleymanova L. , Lukuttsova N.
Published: October 2024

When designing luminescent concrete, an important factor is the functionality of the material, ensuring initial brightness and a long afterglow time. The color of the luminescent pigment affects the performance properties of the material. The research was made to study the effect of pigment color and reflective powder content in luminescent concrete on performance properties when charged with different light sources. In this study, authors used white Portland cement CimSA CEM I 52.5 R with a light reflectivity of 80%; reflective powder with a particle size of 75 μm; luminescent pigment SrAl2O4: Eu2+, Dy3+ of various colors: sky-blue, blue-green, yellow-green with a particle size of 25-55 μm. The intensity of the afterglow of the luminescent pigment in concrete is affected by two factors: the power of the luminous flux and the color temperature. To study the phase of intense afterglow and its duration, researchers used a charging method with different light sources. The influence of external factors on the afterglow brightness of a luminescent pigment for a specific chemical composition and pigment layer thickness is determined by the charging time, the luminescence intensity of the radiation source, and the spectrum structure of the radiation source. After adding reflective powder, the number of light transmission channels increases, so the luminescent effect of the material improves. The analysis showed that the order of intensity of the emission spectrum of luminescent pigments at the same excitation time is: yellow-green > blue-green > sky-blue.

Published: October 2024

The article presents the data obtained during the study of a local exhaust device activated by a perpendicular ramjet positioned in the plasma cutting zone in the outlet space of a thermal heterogeneous jet. In addition, there are the results of numerical modeling of various options for activating the suction flow (increasing the range of the suction flow), which made it possible to determine the geometric parameters of the device and determine the range of variation of flow rates for the formation of a limiting radial jet and to achieve the absence of negative interaction between the supply radial limiting jet and the suction flow for the proposed design of the local exhaust device. The results of experimental studies of the proposed design of the suction device obtained by numerical simulation are presented. The design features of the device implementing the specified method of activating the suction flow are described. The technological and production factors of plasma cutting technology of various metals are described, which influenced the choice of the method of positioning the exhaust device of the design proposed based on the results of modeling, and harmful production factors are also considered, the predominant of which is harmful emissions formed during plasma cutting (dust, aerosols, toxic compounds, gases). Experimental data obtained by modeling the interaction of a suction and radially directed limiting flow are obtained and substantiated.
THEORETICAL DESCRIPTION OF WATER DISTRIBUTION IN CONCRETE MIX-TURES ON LIGHTWEIGHT AGGREGATE
Authors: Inozemcev A. , Korolev E.
Published: October 2024

Based on the models considered, it has been demonstrated that a lower density of hollow agreegate requires a smaller amount of it to achieve a given density of lightweight concrete. This provides greater variability in the development and design of the frame-forming part and creates the potential for achieving high mechanical properties. The proportion of adsorption water of a hollow aggregate does not depend on the total amount of water in the system, in contrast a porous aggregate. This allows predicting water consumption and managing the rheotechnological properties of mixtures based on them. The distribution of physically bound water in compositions on hollow aggregate is different from that in compositions on porous aggregate. The proportion of physical water on such an aggregate is greater than on a hollow one for compositions with a density of no more than 1500...1600 kg/m3. If the density is less than this range, then in hollow aggregate systems a higher content of such water is observed.
It is shown that the distribution of water in systems on porous and hollow aggregate differs significantly. Considering the role of porous aggregate in forming the structure of lightweight concrete, it can be assumed that when developing lightweight concrete with a density of more than 1600 kg/m3, it is advisable to use porous aggregate. When developing lightweight concrete with a density of less than 1600 kg/m3, it is advisable to use hollow aggregate. This ensures rational distribution of water in the concrete mixture and, consequently, conditions for the formation of a strong structure of lightweight concrete.

Para elas, a abordagem terapêutica com anticoagulante oral Varfarina se faz relevante. Tal medicamento, no entanto, precisa ser utilizado associado a monitorização do (INR) e às intervenções terapêuticas, para melhor resultado.  Objetivo: caracterizar pacientes acompanhados em um ambulatório de anticoagulação em relação ao Índice de Complexidade da Farmacoterapia (ICFT).  Método: pacientes previamente selecionados, em uso de varfarina e acompanhados em um ambulatório de anticoagulação, no período de dezembro de 2018 a fevereiro de 2019. Para avaliação do ICFT, utilizou-se o instrumento Medication Regimen Complexity Index (MRCI). A complexidade foi subdividida em três níveis: baixa (<9), média (≥9 ≤16,5) e alta (>16,5) complexidade, conforme indicado pela literatura. A análise da complexidade foi realizada por dois pesquisadores de forma independente.   Resultados: Um total de 93 pacientes foram incluídos no estudo, sendo a média de idade de 63 anos e a maioria do sexo feminino (68,8%). A fibrilação atrial (FA) foi a indicação da ACO mais predominante (92,5%). A média do número de medicamentos utilizados foi de 7,0. A maioria dos pacientes com farmacoterapia classificada como alta (38, 6,5%) e média complexidade (24, 80,7%) apresentou TTR inadequado. Conclusão: O presente estudo permitiu identificar que há um predomínio de pacientes com alta complexidade da farmacoterapia, o que pode indicar necessidades de cuidados adicionais em relação ao tratamento anticoagulante. Para tanto, é necessário avaliar o controle da anticoagulação satisfatório, a fim de que o serviço de saúde prestado a esse público possa ser aprimorado, de forma a gerar maior segurança e um melhor desfecho no controle da anticoagulação.
The Synchronous Online Environment: Impact on Instructor’s Academic Empathy
Authors: Huggins Lystra
Published: October 2024

The COVID -19 pandemic has ushered in a new era of pedagogical strategies and offered a unique window into students’ lives. Among the many challenges and advantages of the online environment, the daily exposure to students’ lives—magnified during synchronous online teaching—served to humanize them in the classroom. This research delves into a novel area, exploring whether this heightened exposure to students’ day-to-day environments outside of the physical classroom leads to academic empathy from their instructors and whether it results in a better understanding of students’ individual challenges and circumstances. The results showed that synchronous instruction increased faculty members’ empathy for students’ diverse personal experiences. A significant discovery, however, was the role of student camera usage in enriching the synchronous online experience. Ultimately, the study underscores the benefits of students having cameras on during synchronous online classes to create a more connected and empathetic classroom environment.

Исследование проводили для оценки влияния раннего измерения концентрации дигоксина в сыворотке крови (сывороточная концентрация дигоксина, СКД) на терапевтическую безопасность и эффективность применения препарата у пациентов старших возрастных групп с недавно возникшей фибрилляцией предсердий и сердечной недостаточностью. Были получены данные о том, что желудочковые аритмии de novo, атриовентрикулярные и синоатриальные блокады высокой степени были отмечены у 22 %, причем риск их развития имел прямую корреляцию с конечным значением СКД (среднее значение СКД — 0,88±0,78 нг/мл против 0,45±0,71 нг/мл; p=0,039) независимо от базовых характеристик. Эмпирические калькуляторы длительного мониторинга дигоксина коррелировали как с СКД (r=0,54...0,58; p=0,008...0,003), так и с риском развития нарушений проводимости. Повторные госпитализации по неотложным сердечно-сосудистым показаниям в течение 10 мес были связаны с более высокой конечной СКД (0,82±0,77 нг/мл у госпитализированных пациентов против 0,42±0,44 нг/мл у негоспитализированных, p=0,009), при этом не было корреляции исходной СКД с летальными исходами. Таким образом, ранний мониторинг СКД может минимизировать риск нежелательных явлений при лечении фибрилляции предсердий. Существующие эмпирические калькуляторы СКД также могут применяться в клинической практике, но их прогностическая ценность для оценки долгосрочной безопасности терапии дигоксином остается неясной и требует дальнейшего изучения.

To evaluate the effect of early measurement of serum digoxin concentration (SDC) on therapeutical safety and efficacy in patients with recent-onset atrial fibrillation and heart failure. De novo ventricular arrhythmias, high-grade AV node or sinus node blocks were noted in 22 %, this risk was positively associated with endpoint SDC (mean SDC 0,88±0,78 ng/ mL vs 0,45±0,71 ng/mL, p=0,039) irrespective of baseline characteristics. Empiric calculators for long-term digoxin monitoring correlated with both SDC (r=0,54...0,58, p=0,008...0,003) and risk of conductivity disturbances. Re-hospitalizations by urgent cardiovascular indications within 10 months were associated with higher endpoint SDC (0,82±0,77 ng/mL in hospitalized patients vs 0,42±0,44 ng/mL in non-hospitalized, p=0,009), with no association between early SDC and deaths. Early SDC monitoring may minimize the risk of adverse events in the treatment of atrial fibrillation. Existing empirical SDC calculators can also be used in clinical practice, but their predictive value for assessing the long-term safety of digoxin therapy remains unclear and requires further study.

Увеличение распространенности ХСН, в том числе у лиц пожилого возраста, является глобальной проблемой. Несмотря на успехи лечения, смертность данных пациентов остается высокой, из-за чего возникает потребность поиска новых механизмов развития и прогрессирования этой патологии сердечно-сосудистой системы, а также разработки инновационных ветвей терапии. Значительный интерес в последнее время направлен на изучение изменения состава микробиоты кишечника у людей с возрастом, ее роли в развитии, а также потенциального направления профилактики сердечно-сосудистых заболеваний и их осложнений. Одним из таких осложнений, особенно у лиц пожилого возраста, где прослеживается несколько линий взаимосвязи с кишечной микробиотой, является ХСН. Патогенетически влияние обусловлено хроническим системным воспалением, а также воздействием кишечных метаболитов на её течение. Цель обзора литературы — анализ и систематизация существующих научных исследований, посвященных связи между микрофлорой, ее изменениями и ХСН, а также изучение методов воздействия на звенья патогенеза, что в свою очередь способно остановить прогрессирование данного осложнения заболеваний сердечно-сосудистой системы. В обзоре представлены источники литературы, опубликованные преимущественно в период 2019–2024 гг., с использованием баз данных PubMed, ScienceDirect, eLIBRARY, включая обзорные статьи, метаанализы, клинические исследования.

The increasing prevalence of chronic heart failure (CHF) among older people is a global problem. Despite the success of treatment, the mortality rate of these patients remains high, resulting in the need to search for new mechanisms of the development and progression of cardiovascular system pathologies, as well as to develop innovative branches of therapy. Considerable recent interest has been directed towards studying changes in the composition of the intestinal microbiota in people with age, its role in development, as well as potential directions for the prevention of cardiovascular diseases and their complications. One of these complications, especially in the elderly, where several lines of relationship with the intestinal microbiota can be traced, is CHF. Pathogenetically, the effect is due to chronic systemic inflammation, as well as the effect of intestinal metabolites on its course. The objective of this literature review is to analyse and systematize existing scientific studies on the relationship between microflora, its changes and chronic heart failure, as well as to study methods of dealing with the links of pathogenesis, which in turn can stop the progression of this complication of SSS diseases. The review presents literature sources published mainly in the period 2019–2024 using PubMed, ScienceDirect, eLIBRARY databases, including review articles, meta-analyses, clinical studies.

Представлена гипотеза, согласно которой активация ретроэлементов при старении, вызывающая иммунные реакции в организме человека, служит пусковым механизмом развития остеоартрита. Фактором предрасположенности к этому являются ассоциированные с болезнью полиморфизмы, расположенные в интронных и межгенных областях, где локализованы мобильные элементы. В воспаленных суставах определяется изменение экспрессии множества генов, что может быть обусловлено патологической активацией ретроэлементов, влияющих на эпигенетическую дизрегуляции генома. В качестве подтверждения гипотезы представлены данные о том, что у больных остеоартритом в клетках крови выявляют активированные ретроэлементы LINE1, ERV3, HERV-K18, а в тканях суставов определяют продукты экспрессии эндогенных ретровирусов HERV-E2 и HERV-WE1, снижение активности деацетилазы гистонов Sirt6. Анализ базы данных MDTE и научной литературы позволил выявить 12 микроРНК, произошедших от LINE, 5 — от SINE, 2 — от HERV, влияющих на патогенез остеоартрита и вовлеченных в механизмы старения, что может свидетельствовать в пользу представленной гипотезы.

A hypothesis is presented according to which the activation of retroelements during aging, causing immune reactions in the human body, is a trigger for the development of osteoarthritis. Predisposition factors for this are polymorphisms associated with osteoarthritis, located in intronic and intergenic regions where transposable elements are localized. In inflamed joints, changes in the expression of many genes are determined, which may be due to pathological activation of retroelements that influence epigenetic dysregulation of the genome. To confirm the hypothesis, data are presented that in patients with osteoarthritis, activated retroelements LINE1, ERV3, HERV-K18 are detected in blood cells, expression products of endogenous retroviruses HERV-E2 and HERV-WE1 and a decrease in the activity of histone deacetylase Sirt6 are detected in joint tissues. Analysis of the MDTE database and scientific literature revealed 12 microRNAs derived from LINE, 5 derived from SINE, 2 derived from HERV, affecting the pathogenesis of osteoarthritis and involved in the mechanisms of aging, which may indicate in favor of the presented hypothesis.

Wastewater data, including Population of the Municipality Served by the Wastewater Treatment Plants (WWTPs), Capacity, Number of WWTPs, Amount of Daily Wastewater Discharged per Person and Wastewater Treated in WWTPs (y(t)) obtained from Turkish Statistical Institute (TUIK) for Kayseri province for 2003-2020 were mathematically modelled and analysed with Artificial Neural Network (ANN) and Differential equations. Firstly, the data were augmented through ARIMA since TUIK data numbers are insufficient to ANN training and later the data were normalized. The augmented normalized data was trained with ANN twice, thus the effect of other variables on the y(t) variable was shown and mathematical ANN activation functions in the form of a tangent hyperbolic function was proposed for this variable. Then, arbitrary parameters used for a linear system consisting of differential equations representing the five variables mentioned above were estimated using normalized original data and thus the ODE (ordinary differential equation) model was proposed. Two ANN models and ODE model were evaluated on normalized real TUIK data and the performances of these three models were compared. Among these mathematical models, the model that gave the minimum MSE (mean squared error) has been determined as the ODE model. Finally, future predictions were made for the y(t) variable with the ODE model.
