Improvement of exploitation of existing HPPs is important task. One of the most interesting aspects is improvement of overall efficiency of HPPs steady-state regimes. Achievement of higher efficiency results in reduction of water consumption. The saved and stored water allows for additional energy generation at the HPPs. The paper presents methodology for analysing optimal intra-station regimes of HPPs (a.k.a. optimal unit allocation/dispatching) availing with asymmetric energetic haracteristics of gen-units and waterways, i.e. the HPPs developed and commissioned in two stages, run-of-river HPPs availing with several large and one small gen-unit for releasing guaranteed discharge, as well as multi-unit HPPs during the course of refurbishment/uprating. The optimization model is able to cope with various technical constraints, i.e. boundaries of turbines’ exploitation ranges, as well as total spinning reserve and manoeuvrability of load variations of the active gen-units of HPP. A Case Study of Vlasinske HPPs is presented. Findings show that for the analysed asymmetric HPPs energy generation over longterm periods can be increased for over 3%, as well as the revenues of the owner companies.

Hydrogen has been strongly proposed as one of the possible solutions to energy transition lately. On the other hand, it is an accepted fact that fossil fuels will make up at least 50% of primary energy sources after 2050. Natural gas is considered a primary fuel that satisfies the energy decarbonization concept to a certain level. Knowing the advantages and disadvantages of natural gas and hydrogen, as gaseous fuels, mixtures of these two gases may appear as an optimum solution during the energy transition period. This paper deals with the properties of natural gas and hydrogen that affect the combustion process and burning systems. The effects on combustion systems performance, are analyzed.

This paper describes the possibilities of use developed Dignet Energy Platform (DEP) – platform for modeling and optimization of bioenergy production. DEP presents a set of software tools based on a mathematical model that calculates the desired outputs and the profitability of the investments in this type of renewable energy source based on input parameters by using Multi-Criteria Decision Analysis (MCDA). This tool enables the simplification of complex, biomass-based energy production related calculations, while also enables the customization of each individual element in the bioenergy production process. The user is able to use a simple procedure to „simulate“ the production parameters and choose the best option from a set of biomass-based projects. Several aspects of selected project quality assessment are enabled based on defined criteria calculated for each desired project type. These criteria are: energy efficiency f1 (without the dimensional value), total investment in the production chain f2 (EUR), fuel, heat, and/or electricity production price f3 (in EUR/ton or in EUR/kWh), CO2 emission in the biomass fuel, heat, and/or electricity production chain f4 (in kg CO2/t or in kg CO2/kWh) and exergetic factor of the quality chain f5 (dimensionless). This paper describes a simple protocol for use of DEP. As an example in this paper, three chains of biomass fuel production are taken: a chain for the production of wood chips, a chain for the production of straw bales and a chain for the production chips from miscanthus. All chains related to the setting conditions applicable to the Republic of Croatia, and the region. The DEP platform is a very usable tool that quickly selects the optimal project based on biomass with a large amount of information needed for its further development.

The testing and development of an electro-thermal post-combustion system for single-room fireplaces is the focus of this article. The aim is to reduce carbon monoxide (CO) emissions and particulate matter of traditional single-room fireplaces, which typically have high emissions of pollutants, at least in some combustion phases. Those emissions are nowadays a problem for even wider use of wood for domestic heating, which is otherwise a renewable source of energy. The electro-thermal post-combustion system was tested in a fireplace available on the market. It was heated by an electric heating element to a temperature high enough to ignite the unburned gases and particles in the flue gas. The system was designed and optimized by placing ceramic plates with a heating wire passing through the plates and a prototype was built and assessed in a laboratory setting. The performance of the system was evaluated in terms of its ability to reduce CO and especially fine particles emissions, and maintain high temperatures. The results of the tests showed that the electro-thermal post-combustion system was able to reduce some emissions of CO and especially PM. The system was also able to provide high temperatures in the post-combustion chamber. During the normal operation of the furnace, temperatures reach up to 450-550 °C which is not enough for CO to burn completely. However, temperatures of 800°C are necessary for the complete combustion of CO. Overall, the study demonstrates first steps towards the full potential for electro-thermal post-combustion systems to significantly reduce CO emissions and PM of single-room fireplaces, which can have a positive impact on air quality and renewable energy usage in residential settings.

Authors: Ribeiro Eric Tenaglia Abrantes , Ribeiro Eduardo Dias , Aguiar Ana Helena Duarte , Leite Josélia da Silva
Published: September 2024

O objetivo geral deste estudo foi avaliar os efeitos do uso da plataforma switching para fins ortodônticos. A metodologia consistiu na revisão da literatura, aonde se fez o processo de busca, análise e descrição de um corpo do conhecimento com a finalidade de obter de resposta a pergunta que problematizou a pesquisa. Afirma-se que a utilização da plataforma switching tem sentido promissora e eficiente para a implantodontia, uma vez que existirá a migração do infiltrado de células inflamatórias para perto da região central do eixo do implante e distante da crista alveolar, de modo a trazer os limites da reabsorção do osso. Em pesquisa clínica e radiográfica empreendida para avaliar o efeito biológico da plataforma switching comprovou-se que a reabsorção óssea foi de 0.95 mm nos implantes com esse tipo de plataforma, enquanto que o grupo controle demonstrou 1.67 mm de perda óssea. A utilização da plataforma switching pode cadenciar determinadas vantagens do que diz respeito a reabilitações implantossuportadas, como, por exemplo, a diminuição na reabsorção óssea na crista marginal.

É necessário ao ortodontista compreender as propriedades dos elásticos, sejam eles em látex ou sintéticos, além de suas limitações e riscos, para atingir resultados com eficiência e previsibilidade.
Towards a Historical and Philosophical Rethinking of Late Antique and Byzantine Thought. Book Review: Dugin A. G. Noomachy: Wars of the Mind. Byzantine Logos. Hellenism and Empire. M.: Academic Project, 2016. 519 p.
Authors: Медоваров М.В.
Published: September 2024

Рассматривается книга А. Г. Дугина, входящая в цикл «Ноомахия» и посвященная философии эпохи эллинизма, поздней античности, Византии и современной Греции. В центре внимания находится методологическая и эвристическая ценность ноологической концепции «трех Логосов», через которую дается оценка различным историческим и культурным сдвигам в многотысячелетней истории греческой культуры. Особое внимание уделено оценкам языческих и христианских философов в свете неоплатонического понимания истории эллинистически-римской и византийской философии.

There is reviewed the book by Alexander Dugin being part of the “Noomachy” cycle and dedicated to the philosophy of the Hellenistic era, late Antiquity, Byzantium, Modern and contemporary Greece. The focus is made on the methodological and heuristic value of the noological concept of the “three Logoses”, through which various historical and cultural shifts in the millennia-long history of Greek culture are assessed. Particular attention is paid to the assessments of pagan and Christian philosophers in the light of the Neoplatonic understanding of the history of Hellenistic-Roman and Byzantine philosophy.
Averintsev and the Paschal Joy. On the Perception of Byzantine Christianity in Some Later Works of the Thinker
Authors: Макаров Д.И.
Published: September 2024

В поздних статьях, выходивших на русском и английском языках, а также в монографии о Вяч. Иванове С. С. Аверинцев выделяет некоторые системообразующие черты византийского Православия — такие, как онтологизм, пасхальная радость, литургическое переживание радости и умиления, вызванное молитвенным переживанием Богородичного общения, центральное значение иконы, передающей человеческий Лик Господа Иисуса Христа. Также разбирается такой вводимый мыслителем в 90‑е гг. концепт, как «христианская геополитика»; подобные мысли восходят к традиции византийской и европейской консервативной философии (Томас Карлейль, отчасти Феодор Метохит). Концепция Аверинцева, феноменологически тончайшим образом описывающая византийское благочестие изнутри, противопоставляется внешне-барочному описанию византийской религиозности у Х.-Г. Бека, ставящего акцент на проблеме византийского воображаемого. Подчеркивается преемственность Аверинцева по отношению к мысли Вяч. Иванова и Н. С. Трубецкого.

In some later articles of his, published in English and Russian, as well as in the monograph on Vjacheslav Ivanov, Sergei S. Averintsev has singled out some basic features of the Byzantine Orthodoxy, such as its ontological character, the Paschal joy, liturgical experience of rejoicing and deep tenderness, which used to be caused by the communication with the Holy Virgin in prayer, and the central meaning of icon, which transmits to us the human Face of our Lord Jesus Christ. We also analyze such Averintsev’s concepts from the nineties of the 20th century, as “Christian geopolitics”; such-kind ruminations go back to the tradition of Byzantine and European conservative philosophy (Th. Carlyle, and — partially — Theodore Metochites). This Averintsev’s conception, which phenomenologically describes in the most subtle way the Byzantine piety from within, is juxtaposed to the outer, Barock-like description of the Byzantine religiosity produced by Hans-Georg Beck, the great German scholar putting his emphasis upon the problem of the Byzantine imaginary. We underscore Averintsev’s continuity in thought with Vjacheslav I. Ivanov and Nicholas S. Trubetzkoy.
Canonization of the Autobiographical Myth of Vyacheslav Ivanov in the Works of S. S. Averintsev
Authors: Кибальниченко С.А.
Published: September 2024

Автобиографический миф, созданный поэтом и теоретиком символизма Вячеславом Ивановым, имеет сложную структуру. Его ядро сформировано целенаправленными усилиями самого писателя. Второй слой возник благодаря «семейному» биографу Ольге Шор (Дешарт). Осязаемым его воплощением стало четырехтомное собрание сочинений Иванова, изданное в Брюсселе. Третий слой создан знаменитым филологом С. С. Аверинцевым, который на протяжении трех десятилетий публиковал научные работы, посвященные поэту. Их отличает апологетический стиль и полное приятие образа Иванова, созданного им самим. Благодаря такому подходу в работах Аверинцева произошла канонизация автобиографического мифа поэта. Он лишился налета субъективности и во многом совпал с магистральной линией интерпретации творчества писателя в литературоведении. Недаром среди многочисленных научных публикаций об Иванове практически нет работ, посвященных автобиографическому мифу. В настоящей публикации делается первый шаг к осознанию этой проблемы и уточняется понятие «символистского канона».

The autobiographical myth created by the poet and symbolist theorist Vyacheslav Ivanov has a complex structure. Its core is formed by the purposeful efforts of the writer. The second layer arose thanks to the “family” biographer Olga Shor (Dechart). Its visible embodiment was the four-volume collected works of Ivanov, published in Bruxelles. The third layer was created by the famous philologist S. S. Averintsev, who for three decades published scientific works dedicated to the poet. They are distinguished by an apologetic style and complete acceptance of the image of Ivanov, created by himself. Thanks to this approach, Averintsev accomplished the canonization of the poet’s autobiographical myth. The autobiographical myth lost the touch of subjectivity and largely coincided with the main line of interpretation of the writer’s work in philological science. It is not surprising that among the numerous scientific publications about Ivanov, there are practically no works devoted to the autobiographical myth. This publication takes the first step towards understanding this problem and clarifies the concept of the “symbolist canon”.

Sustainable Value Co-creation Between Financial Services Firms and Microenterprise Customers: is Digital the Missing Link?
Authors:   Council for Scientific and Industrial Research, Ghana, PO Box AN6041, Accra-North, Accra-Ghana, Abban Rita
Published: September 2024

This paper investigates how financial services providers (FSPs) can engage in value cocreation with their microenterprise customers (CMEs) for sustainable value cocreation. The potential of digital for value cocreation in inter-firm relationships is relevant because digital technologies such as mobile phone and internet platforms are rapidly transforming the business landscape. The research question addressed is how do financial services firms and microenterprises engage in sustainable value co-creation? It is a qualitative study (using phenomenological interviews and observations) of financial service providers (FSPs) and their microenterprise customers (CMEs) in Ghana. The study builds on the model of Selander et al., (2010) by making contributions to sustainable value co-creation determined through equitable growth supported by (1) entrepreneurial strategies, which are specified as the boundary definition and are directly related to the firm’s innovation; (2) continuous innovations, which are the locus of innovation ranging from process to product emphasis; and (3) monitoring, which is the mode of control used by the firm to capture value from its technology. Our study findings support the conclusion that digital is the missing link to sustainable value cocreation through collaborating.

Published: September 2024

Gydytojų mitybos įpročiai yra svarbūs tiek pačių specialistų, tiek jų pacientų sveikatai. Nors gydytojų žinios apie sveiką mitybą yra plačios, jų darbo ypatumai kelia didesnę riziką susiformuoti prastiems mitybos įpročiams, kurie skatina lėtinių ligų išsivystymą, sutrikdo kognityvinę funkciją.
Tyrimo tikslai. Nustatyti gydytojų mitybos įpročius ir požiūrį į sveiką mitybą, įvertinti gydytojų mitybos įpročių sąsajas su gydytojų savijauta bei darbo ypatumais.
Tyrimo medžiaga ir metodai. 2024 m. vasario–kovo mėnesiais buvo atlikta anoniminė savanoriška anketinė apklausa, kurioje dalyvavo 146 respondentai. Tyrimui naudotas specialiai sudarytas klausimynas, kuriame rinkti gydytojų sociodemografiniai, antropometriniai duomenys, gydytojams užduoti klausimai apie darbo ypatumus bei sveikatos būklę, požiūrį į mitybą, valgymo įpročius, mitybos raciono ypatumus. Statistinė analizė atlikta naudojantis IBM SPSS 21 ir Microsoft Excel programomis.
Rezultatai ir išvados. Tyrime dalyvavo 14,4 proc. vyrų ir 85,6 proc. moterų. Dauguma apklausos dalyvių sveiką mitybą laiko labai svarbia arba svarbia, o šis vertinimas priklauso nuo darbo pobūdžio. Visgi apie 70 proc. respondentų teigė esantys nepatenkinti savo mitybos įpročiais. Nors dauguma iš jų skiria pakankamai laiko pavalgyti, valgo namie gamintą valgį, vartoja daug daržovių bei vaisių, tačiau yra linkę užkandžiauti, valgo nereguliariai, praleidžia pagrindinius valgymus, valgo vėliau nei 20 valandą. Nereguliarus valgymas priklauso nuo to, ar darbas yra dieninis, pamaininis ar mišrus. Dažniausiai nepavalgoma dėl laiko stokos ir pertraukų trūkumo. Nustatyta, kad gydytojai, kurie praleidžia pagrindinius valgymus, dirba daugiau valandų per mėnesį nei tie, kurie nepraleidžia valgymų (p = 0,048). Didesnė dalis gydytojų savo sveikatos būklę vertina kaip labai gerą ar gerą, bet 12,3 proc. nurodė sergantys bent viena metaboline ar kardiovaskuline liga.

Authors: Shekarau Juliet David , Mustapha Rabi , Haruna Khalid
Published: September 2024

As the Internet aims to integrate and connect anything at anytime, anyplace with anything and by anyone, cyberattacks develop in volume and complexity with Botnets which are used in a wide range of malicious activities such as e-mail spamming; Phishing, social engineering, and even distributed denial of service (DDoS) attack. This incessant increase of attacks necessitates the interests in detecting and preventing botnet attacks in network and internet-based systems. This study develops a hybridized Deep Stacked Autoencoder optimized with Genetic Algorithm (DSAE-GA) for the classification and identification of intrusions from the internet environment. The hybridized DSAE-GA model primarily used Principal Component Analysis (PCA) technique to select a subset of features. The DSAE was trained to learn the normal network traffic profile using the Context Computer Network Traffic (CCNT) dataset while adapting to reconstruct these points with minimal reconstruction error (RE). The design of the GA majorly focuses on the parameter optimization of the DSAE thereby enhancing the classifier results.

Published: September 2024

Cloud computing is one of the result of rapid growth of computing technology which has now affect the very way by which organizations and individuals uses IT resources such as application, storage, etc. by providing shared virtual versions of such resources which comes with the benefit of reducing the cost of hardware and software installation, but the concerns of organizations lies within the security and privacy of their data at rest on the cloud storage, among such concerns are the unauthorized usage by possible malicious insider within the cloud provider organisation and other cloud users. Despite the fact that service providers used many mechanisms to protect unauthorized access to data stored in their cloud storage, but there is no any mechanism to protect unauthorized access to the client’s data by the cloud service administrator. In this work we show how a steganography which is a technique of concealing the existence of a data inside a cover medium can be used to improve the security of data in the cloud by using additional layer of security that is user centric. However, the application of the proposed technique is implemented using a particular case study.

Authors:   The Foodservice Management Society Of Korea, Jang Eunyoo , Cho Meehee
Published: September 2024

This study aims to understand the mechanism of Self-Service Technology(SST) adoption in senior diners. This study was based on Technology Acceptance Model (TAM) and Senior Technology Exploration, Learning, and Acceptance (STELA) model. This study obtained data from 236 senior diners who have prior experience in using SST in the restaurant context for the analysis. Technostress significantly affected perceived usefulness of senior diners while social influence did not have such an effect. The perceived usefulness exhibited a positive attitude toward the use of SST, thereby leading to greater exploration and higher acceptance intentions. Additionally, exploration of senior diners improved the perceived ease, which in turn increased their acceptance intention. The findings can be utilized for future relevant research and development of effective strategies for restaurant businesses.

Authors:   The Foodservice Management Society Of Korea, Jeon Do-Hyun , Jeon Hyeon-Mo
Published: September 2024

Objective:This study was conducted by developing a hypothesis and investigating the effect of consumer expectations on cognitive dissonance caused by shrinkflation of food companies when purchasing snacks, and to determine the effect of cognitive dissonance on satisfaction and repurchase intention.
Methods:This study conducted a survey by selecting six confectionery products which have the same price but have reduced amount. The survey was conducted from April 1st to April 20, 2024, and it targeted a total of199 people who had purchased at least one of the six selected confectionery products in the past three months. This study used SPSS 22.0 and AMOS 22.0 programs to analyze the collected data for frequency, reliability, confirmatory factor analysis, correlation analysis, and structural equation modeling.
Results:Pre-purchase expectations were found to have a negative effect on cognitive dissonance. The cognitive dissonance also had a negative effect on satisfaction and repurchase intention.
Implications:When implementing a strategy through shrinkflation, companies should seek sufficient understanding from consumers and provide information that allows comparison between the existing amountand the new amount.
The Moderating Role of Firm Size on Financial Distress in Commercial and Manufacturing State Corporations in Kenya
Authors: Kibe Peter , Wamugo Lucy , Atheru Gerald
Published: September 2024

Purpose: The study attempted to investigate the moderating effect of firm size on relationship between profitability, leverage, efficiency, and financial distress in Commercial and Manufacturing State Corporations in Kenya.
Methodology: The study adopted positivist philosophy that required researcher to be independent of the study. Explanatory non-experimental research design was used in the study. For the purposes of this study, a census of all 25 Commercial and Manufacturing Corporations was employed in study. Study used Secondary data from audited accounts of State Corporations for period 2015-2021 in analysis. Data was obtained from office of auditor general and Kenya Parliament digital library. Researcher used Logit Regression Model to analyse quantitative data. Diagnostics tests included multicollinearity, heteroscedasticity and likelihood ratio tests and Hosmer-Lemeshow goodness of fit tests. Study used STATA Version 13.10 statistical software to analyse data and findings presented using tables
Findings: The study established that firm size did not moderate the relationship between profitability, leverage, efficiency and financial distress in commercial and manufacturing state corporations in Kenya. In summary, the size of State corporations did not influence financial distress. Financial distress equally affected both small and big Commercial and Manufacturing State Corporations contradicting the theory of small firms.
Unique Contribution to Theory, Practice and Policy: Top management of State Corporations should monitor key financial ratios including profitability, leverage and efficiency ratios. These ratios will assist those charged with governance in developing strategic plans and turnaround strategies to bring back to life the distressed state corporations so that they can contribute positively towards growth of the economy. The study concluded that there is a dire need by State Corporations to reduce reliance on government loans and bailouts by engaging efficiently in profitable ventures that would maximise the wealth of the firm. The study also concluded that profitability, leverage and efficiency were useful ratios to management and those charged in detection and mitigation of financial distress. The study recommended that in order to increase profitability, commercial and manufacturing state corporations should improve their operational efficiency and reduce use of debt particularly the government guaranteed loans.
Bureaucracy in School Administration: A Grounded Theory Study
Authors: Balıkçı Abdullah
Published: September 2024

The aim of this study is to put forward a model for an effective bureaucratic administration structure in school administration, based on the interaction between school administration and Weberian bureaucracy. According to the research conducted with the participation of 27 school administrators and grounded theory design, bureaucracy has two aspects in terms of school administration. Bureaucracy contributes to the school administration in terms of maintaining the work in a certain order, giving importance to the field of expertise, allowing everyone to speak the same language by carrying out the work in an official manner, and being a tool in overcoming problems. On the other hand, it causes work to slow down and progress with difficulty because it brings about unfair practices and causes formalism and waste. When the dimensions of Weberian bureaucracy are examined in the context of school administration, 4 of the 6 dimensions - division of labor, rules and regulations, authority hierarchy and rational behavior - continue to function in school administration. However, it is understood that there are problems in school administration regarding specialization and merit.
In terms of an effective bureaucratic structure in school administration, a structure that takes both the employee and the school into consideration is required. In order to implement an effective and efficient bureaucracy in school administration, all dimensions of Weberian bureaucracy must be taken into account, based on the balance of authority-responsibility and delegation of authority. Additionally, organizational and individual dimensions should be taken into account.

La relación escuela multigrado y comunidad: importancia simbólica, participación política y contexto sociocultural
Authors: Rossainzz Méndez Carlos Guillermo
Published: September 2024

Este artículo analiza antropológicamente las formas de relación entre escuela mul­tigrado y la comunidad local en la Sierra de Chiconquiaco, Veracruz, México. Metodoló­gicamente, la investigación se orientó por técnicas etnográficas, como observación participante, entrevistas semi-estructuradas y grupos focales, que fueron complemen­tadas con indagaciones documentales-bibliográficas. En el apartado de resultados se argumenta que la escuela multigrado y la comunidad local establecen una relación que puede explicarse desde tres dimensiones: la simbólica, cuyo trasfondo es la concentración de desventajas, lo que estimula discursos y prácticas locales sobre la importancia aspiracional y representativa que la escuela tiene; la dimensión organiza­tiva-política, manifestada en prácticas compartidas de gestión y participación escolar, como las faenas escolares, la atención a los maestros y las reuniones escolares, que ejemplifican el impacto de la escuela multigrado como institución con importancia local a la par de la iglesia o las juntas ejidales: y la dimensión sociocultural, que de­muestra cómo se entrelazan rasgos propios del territorio con patrones distintivos de la escuela local, los cuales visibilizan la imbricación de la escuela con la cultural nacional y las expresiones religiosas. En conjunto, se destaca como conclusión principal que, culturalmente la escuela multigrado trasciende el sentido instruccional-curricular que históricamente se le atribuye, cobrando mayor relevancia como una organización co­munitaria donde se depositan los anhelos de desarrollo y de representatividad local.

Review of literature was carried out on ‘Google Scholar’ and in the library of Maharashtra Institute of Pharmacy, Betala, Tal. Bramhapuri, Dist. Chandrapur, Maharashtra (India). The review was carried out with objective to collect information about parameters, methods and findings published by different researchers on analysis of B. monosperma flowers. It was seen that researchers have carried out studies on organoleptic properties, morphology, microscopy, physicochemical parameters, phytochemical evaluation, thin layer chromatography, HPTLC and HPLC analysis of B. monosperma flowers. This article provides details of methods and findings of studies carried out by different researchers on evaluation of B. monosperma flowers. It was noted that very limited number of studies have been published and most of them are based on single sample hence there is scope to carry out more studies on more number of samples of B. monosperma flowers so that it can be helpful to establish standardization parameters for B. monosperma flowers.
Environmental Degradation And Renewable Energy
Authors: Mr. Satpute Santosh Suryabhan
Published: September 2024

Environmental degradation, a pressing global concern, is primarily driven by the excessive use of fossil fuels. The burning of coal, oil, and natural gas releases harmful pollutants into the atmosphere, contributing to climate change, air pollution, and water contamination. This degradation poses serious threats to human health, biodiversity, and ecosystems. Renewable energy sources, such as solar, wind, and hydropower, offer a promising solution to mitigate these challenges. By transitioning away from fossil fuels, we can significantly reduce greenhouse gas emissions and protect our planet's natural resources. However, the implementation of renewable energy technologies also presents challenges, including high upfront costs, intermittent energy production, and potential environmental impacts. Addressing these issues requires concerted efforts from governments, industries, and individuals to accelerate the adoption of clean energy solutions and ensure a sustainable future

Authors: Shafique Ayesha , Jamil Amber
Published: September 2024

Purpose: The study's primary aim is to inquire the job content plateau to employee psychological withdrawal behavior with mediating role of felt obligation and moderating by supervisor mentoring and theorized by social exchange theory.
Methodology: 268 service sector employees from Pakistan’s twin cities (Rawalpindi and Islamabad) at various hierarchical levels completed a survey questionnaire encompassing 21 items with a 5- point Likert scale. To assess the impacts, we used SPSS 24.
Findings: The findings of this study showed that job content plateau has a significant positive relationship with employee withdrawal behavior, mediated by loss of obligation. While supervisor mentoring moderate the relationship between loss of obligation and withdrawal behavior.
Implications: This suggests that companies can take constructive steps to manage plateaued people by modifying their beliefs and, as a result, their unfavourable attitudes toward their jobs. Organisations should re-evaluate their reward systems in light of the evidence suggesting that aspiration for promotion causes the plateau-outcome link.
Originality: By using data to establish a causal association between job content plateau and employee withdrawal behavior, this study contributes usefully to the career-development literature
