Published: October 2024

U globalnom okruženju sa brzim razvojem tehnologija, automatizacijom, digitalizacijom te novim ekonomskim i društvenim izazovima poput klimatskih promena, pandemija i demografskih promena, ključno je da pojedinci steknu odgovarajuće kompetencije. Kako bi se omogućio prelaz ka novoj digitalnoj (i zelenoj) ekonomiji potrebna su značajna ulaganja u ljudske resurse kako bi se podržali socijalni programi. Novi, potrebni obrazovni kadrovi koji su neophodni za rast i razvoj izrasti će samo u kvalitetnom obrazovnom sistemu. Na kvalitet obrazovnog sistema utiče obrazovni kadar, a uoliko želimo maksimalno izvući iz njega potrebni su nam motivisani, stručni i inovativni edukatori. Nastavni kadar nikada nije bili u zahtevnijoj situaciji; slabe naknade i kompenzacije za rad, nedovoljno motivisani učenici te prevelik pritisak javnosti neki su od faktora koji mogu izazvati nezdravo radno okruženje, stresno okruženje koje negativno utiče na radnu motivaciju. Kako su ljudski resursi postali najskuplji kapital svake organizacije, a motivacija za rad postala značajan faktor u održanju zadovoljstva zaposlenih, prvenstveno je potrebno utvrditi koji faktori negativno utiču na motivaciju zaposlenih u svrhu ostvarenja zdravog radnog okruženja.

Published: October 2024

The food industry's role in developing any economy cannot be over-emphasized due to the significant investment of disposable income into the sector. However, the sudden emergence of the COVID-19 pandemic attracted global attention and significantly disrupted many countries' economic sectors. The study determined the production pattern of the Bakeries in Abuja and further assessed the impact of the COVID-19 pandemic on Bakery performance in Abuja.
The study covers only staff selected from twenty (20) bakeries in Abuja using a multistage sampling technique. The first stage involved the selection of twenty (20) bakeries extracted from the listing of master baker’s association of Abuja using a purposive sampling technique. The second stage is the selection of ten (10) staff from each selected bakery in the study area using a simple random sampling technique, thus, making a total of 200 respondents to participate in the study. Data were obtained using a set of questionnaires along with interviews. Secondary data were sourced from the internet, libraries, Journals and reports. Data obtained were analysed using frequency counts, percentages, mean ratings, and Analysis of variance (ANOVA).
The study revealed that Bakeries made nine (9) distinct aggregate products in Abuja. These comprise a combination of butter-filled Bread, Chocolate Bread, Wheat Bread, and Low-fat Bread.  These products were indicated to be produced always by the bakeries. Finally, the analysis showed that there is a statistically significant (P<0.05) difference in the variation between the mean rating of Increase in sales volume (2.82), Increase in customer satisfaction (3.38), Increase in customer loyalty (3.49) and Customer buying decision (3.45). The study further shows that there is a statistically significant (P<0.05) difference in the variation between the mean rating of the Bread distribution (2.98).
The study concludes that the COVID-19 pandemic lockdown significantly impacted the performance of bakeries in Abuja and recommends that the adopted quality of products be sustained to enhance this performance.

Authors: Chepn'getich  Marygorrety
Published: October 2024

This study investigates the impact of prison visitation on perceptions, attitudes, behavior change, and recidivism rates among incarcerated individuals. Utilizing a mixed-methods approach, data was gathered through surveys, interviews, and official records from a sample of incarcerated individuals and their visitors. The analysis focused on understanding the role of visitation in shaping attitudes towards rehabilitation and family support and its influence on post-release behavior.
Findings reveal a significant correlation between the frequency and quality of visitation and positive behavioral changes among inmates. Inmates who received regular visits reported higher levels of motivation for rehabilitation, improved mental health, and increased feelings of connection with their families and communities. Moreover, visitation played a pivotal role in strengthening family bonds and social support networks, which are crucial factors in successful reintegration post-release.
Furthermore, the study explored the perceptions and experiences of both inmates and visitors regarding the visitation process, including logistical challenges, emotional dynamics, and barriers to maintaining contact. Understanding these perspectives is essential for enhancing visitation programs and addressing systemic issues that hinder family engagement in the correctional system.
The study also examined recidivism rates among participants and found a notable decrease among those who received frequent and meaningful visitation compared to those who did not. These findings underscore the significance of visitation programs in reducing recidivism and promoting successful reentry into society.
In conclusion, this research highlights the importance of fostering supportive relationships through visitation programs to facilitate positive behavior change and reduce recidivism rates among incarcerated individuals. Implementing policies that prioritize and improve access to visitation can contribute to more effective rehabilitation efforts and ultimately lead to safer communities.

Authors: Caroline Akoth Okuku  , Dr.Ondiwa Simon Oluoch
Published: October 2024

Deposit-Taking SACCOs have been actively recruiting and expanding financial services to promote financial inclusion, reaching out to all segments of society, especially the underserved populations, particularly those marginalized in rural areas. However, during membership recruitment, traits such as loyalty, profitability, engagement, and advocacy set high-quality members apart. These traits play pivotal roles in driving business growth, building brand reputation, and ensuring long-term sustainability. During the loan appraisal and approval process, customer characteristics and their perceived value carry significant weight. Therefore, evaluating member quality in terms of creditworthiness, financial literacy, and the ability to make timely payments stands as the central activity in the loan appraisal and approval process. Nevertheless, the empirical studies that were reviewed have presented diverse findings on this subject. The present study, therefore, investigated the effect of member quality on portfolio quality in deposit-taking SACCOs in Kenya. The study used primary data, and structured and unstructured questionnaires were administered to purposely selected credit managers in deposit-taking SACCOs in Kenya. Results of the study revealed that member quality positively and significantly influences the portfolio quality of DT SACCOs in Kenya (p =0.000<0.05) and R2= 31.9%. These results are essential to SACCO managers, SACCO regulators like SASRA, scholars, and policymakers like the government.

Authors: Eric Muriuki Wanjira  , Isaac Mokono Abuga
Published: October 2024

A performing police service is crucial for any country in ensuring the enforcement of laws, maintaining public order, and preventing crime. Mental health among police officers is very important for their performance. However, mental health issue remains a major challenge within the police service in Kenya. The failure to prioritize mental health has led to increased suicide risk, increased stress and burnout, higher risk of mental health disorders, and reduced resilience and coping skills among police officers in Kenya. Therefore, the study sought to assess the effect of trauma management on the performance of police in Kamukunji Sub-County, Nairobi County. The study was anchored on the institutional theory of Stress. A descriptive survey research design was adopted. The target population consisted of 104 respondents: 12 Administration police, 5 critical infrastructure police units, 8 Kenya police dog units, 4 general service units, 26 general duty police, 18 traffic police departments, and 30 criminal investigation department police from Kamukunji Sub County. A census design was employed to include all responders since the study population was manageable. The study sample included all 110 intended respondents. Primary data was gathered through structured questionnaires and interviews. A pilot study was conducted in Embakasi West Subcounty to test the equipment. Pre-tested questionnaires examined face validity to improve reliability. Cronbach's Alpha was used for internal consistency. The study used both descriptive and inferential statistics. The analyzed data were presented using tables. The study concluded that there is a positive and statistically significant correlation between trauma management and the performance of police in Kamukunji Sub-County, which implies that better trauma management enhances the performance of police in Kamukunji Sub-County. The study recommended that authorities overseeing police departments should allocate sufficient resources to enhance existing mental support services, such as counseling and peer support programs, ensuring accessibility and effectiveness for all officers.

Authors: Salih Güney  , Oğuz Köşlü
Published: October 2024

The purpose of this study is to examine the effect of organizational climate on organizational commitment and the mediating role of organizational culture in this effect. Organizational climate is defined as the perceived atmosphere in an organization, while organizational commitment refers to the loyalty of employees to the organization. Organizational culture, on the other hand, is a collection of values, rituals, and symbols arising from the organization's historical background that guides the behavior of employees. The main hypothesis of this research is that a positive organizational climate will increase organizational commitment and that organizational culture plays a mediating role in this process. To test this hypothesis, a survey has been conducted with employees of a company operating in the construction sector in Çanakkale. The survey consists of scales that measure employee perceptions of organizational climate, organizational commitment, and organizational culture. The data collected from the surveys have been evaluated with statistical analysis methods. The results of the analyses indicate that organizational climate has a significant effect on organizational commitment, which is strengthened through organizational culture.

Authors: Cecilia Achieng Osumba  , Dr. James Mwita
Published: October 2024

This study explored the impact of communication styles on leadership conflicts within the Legio Maria Church in Ugenya. Effective communication is crucial for organizational dynamics, particularly in religious institutions where spiritual authority intersects with hierarchical structures. The Legio Maria Church faces persistent leadership conflicts, often exacerbated by differences in how leaders convey, interpret, and act upon information. These conflicts are influenced by the church's complex web of formal and informal communication channels, which shape power dynamics and organizational cohesion. This research identifies the diverse communication styles employed by church leaders, ranging from direct and open to indirect and informal methods. It examined how these styles impact decision-making processes, conflict-resolution strategies, and overall leadership dynamics. By understanding personal and organizational communication preferences, the study provides insights into the root causes of leadership conflicts. Practical recommendations are proposed, including communication training programs, clear communication protocols, and fostering a culture of openness and respect for diverse communication styles. These measures aimed to enhance leadership cohesion and improve the church's ability to serve its members effectively. This research contributes to the broader discourse on effective communication in religious organizations, offering valuable insights for fostering sustainable leadership practices and organizational harmony within the Legio Maria Church.

The Capacity Development Forum (CDF) is an initiative of the Indian Institute for Human Settlements (IIHS) that aims to bring together diverse stakeholders involved in capacity development in India into a ‘community of practice’ to consolidate learnings from across the country and around the world into a strong and value-added network to consolidate learnings across the country and from around the world. The longer-term objective of the forum is to collaborate on Capacity Development practices and create a repository of knowledge on Capacity Development. The third convening of the IIHS Capacity Development Forum was held on 27-28 June 2024 in a hybrid format – at IIHS, Bengaluru City Campus and online, on the theme: ‘Capacity Development and Behavioural Insights – Implications for Institutional Design and Public Policy’. The CDF 2024 focussed on how the understanding of human behaviour and motivations is key to achieving larger objectives not only at an individual level, but also within institutions and societies. The panels brought together stakeholders from a range of sectors to discuss how nudges and incentives can be used to influence human behaviour at various scales, and how this in turn informs the design, formulation and implementation of policies and programmes to make them more effective. Day 1 of the convening comprised panels that brought together capacity development practitioners from the public and private sectors, to discuss various aspects of policy capacity and enhancing it through incorporating behavioural insights, international perspectives on the role of Capacity Development agencies in developing behavioural science capacity of public officials, and the role of leadership in organisational behaviour change. This was followed by a learning hub on Day 2 focussing on cases from practice incorporating behavioural insights from different sectors, and a game-based learning workshop incorporating behavioural insights and illustrating various biases in human behaviour.

Authors: Chanchí-Golondrino Gabriel E. , Ospina-Alarcón Manuel A. , Saba Manuel
Published: October 2024

Introduction: hyperspectral images, unlike conventional images, are composed of numerous channels that provide detailed information about the spectral signatures of objects. This allows for the identification of the materials that make them up, and given their potential for detecting environmental changes, identifying vegetation in urban settings using effective computational methods becomes relevant.Objective: the objective of this research is to propose a computational method based on Fourier analysis for detecting vegetation in hyperspectral images.Methods: the research was developed in four methodological phases: selection of technologies, acquisition of the characteristic vegetation pixel, determination of phase similarity between the characteristic pixel and vegetation and non-vegetation pixels, validation of the method on a test hyperspectral image. A method was implemented using the spectral and numpy libraries in Python.Results: the Fourier analysis yielded an average phase similarity of 89.89% and a minimum similarity of 64.54% between the characteristic vegetation pixel and 100 training vegetation pixels. For non-vegetation pixels, the average phase similarity was 42.19%, with a maximum similarity of 63.98%. These results indicate that the proposed method successfully differentiates between vegetation and non-vegetation pixels.Conclusion: the results demonstrate that the Fourier-based method can accurately identify vegetation areas in hyperspectral images, showing non-overlapping phase similarities between vegetation and non-vegetation. This validates the effectiveness of the proposed approach in detecting vegetation in urban environments.

Published: October 2024

Background: There are no scales used by stoma and wound care nurses to evaluate the stoma care skills of individuals with a urostomy. Purpose: This study was conducted to investigate the Turkish validity and reliability of the Urostomy Education Scale (UES). Methods: The study sample consisted of 66 patients who had undergone radical cystectomy, were in the 0- to 7-day postoperative period, were older than 18 years of age, had no physical or mental disabilities, had no urostomy complications, and agreed to participate in the study. This study used translation and back-translation to determine the linguistic validity of the UES in Türkiye. Expert opinion was consulted for content validity. Then, 2 competent and 2 experienced nurses evaluated the face validity of the scale with 5 individuals with urostomies. Reliability of the scale was assessed using internal consistency, interrater reliability, and intraclass correlation coefficients. Results: The content validity index was 0.81 and α = 0.66 to 0.95 for the Cronbach’s alpha of the competent nurse assessment and α = 0.68 to 0.96 in the expert nurse assessment. The intraclass correlation coefficient (ICC) results indicated sufficient and statistically significant agreement (ICC range: 0.6-1) between the evaluations made by the 2 evaluators for each skill. Conclusion: The Turkish version of the 7-item UES is a valid and reliable tool that can be used to determine the self-care levels of individuals with a urostomy.

Один из вариантов решения актуальной для горной промышленности задачи выявления максимально возможного количества закономерностей формирования напряженного состояния массива горных пород в различных горно-геологических условиях в ходе ведения горных работ состоит в конкретизации факторов, зависимостей и необходимых условий, определяющих параметры коэффициентов концентрации и деконцентрации напряжений при проявлении опорного давления в характерных зонах выемочных столбов. В настоящее время при решении задач о распределении напряжений в массиве в ходе ведения горных работ в различных условиях в качестве исходных гипотез напряженного состояния угля и пород в не подверженном техногенному воздействию массиве используются различные версии. Анализ существующих гипотез: сплошной среды, пластичной среды, упруго-пластичной среды, наследственной ползучести, плит, балок и результаты натурных исследований, проведённых на шахтах ОАО «СУЭК-Кузбасс» за период 2010-2014 гг., показывают возможность их практического использования для определения параметров опорного давления в ходе разработки паспортов выемочных участков при условии определения диапазона применения, уточнения значений вводимых параметров, с обязательной проверкой результатов расчётов на адекватность.

The actual problem for the mining industry is to identify the maximum possible number of regularities in the rock massif stress state formation in various mining and geological conditions during mining operations. Specifying the factors, correlations and necessary conditions that determine the parameters of concentration and deconcentration pressure coefficients of the support pressure during the specific zones of longwall blocks is one of the possible solutions. At the present, in order to solve the problems of the rock massif pressure distribution, during mining operations under various conditions, the different versions are used as initial hypotheses for the stressed state of coal and rocks in the strata not affected by the man-made impacts. The analysis of the existing hypotheses of continuous medium, yielding medium, elasto-plastic medium, hereditary creep, plates, beams and the results of field survey conducted at the mines of OJSC SUEK-Kuzbass during the period of 2010-2014 years displays the possibility of their practical use for determining parameters of the support pressure during the projects of extraction sites design, taking into account both the determined application range and the specified values of the input parameters, including obligatory verification of the calculation results of for adequacy.

В работе сравнивались два типа непрерывных углеродных волокон (УВ) на основе полиакрилонитрильного волокна: высокомодульное и высокопрочное. Проведена оценка динамики окисления УВ при температуре 600С с выдержкой от 1 до 6 часов. Установлено, что высокомодульное волокно выгорает медленнее, чем высокопрочное. Исследована поверхность волокон в исходном состоянии и после отжигов. Образцы композита с матрицей из сплава Al-6Mg, армированной данными типами УВ, были испытаны на трехточечный изгиб. Установлено, что прочность композита с высокомодульным волокном более чем в 2 раза превышает прочность композита с высокопрочным волокном. Исследованы УВ, извлеченные из углеалюминиевых композитов, и поверхности разрушения образцов композитов после механических испытаний.

Two types of continuous carbon fibers based on polyacrylonitrile fiber were compared: high-modulus and high-strength. The carbon fibers oxidation at a temperature of 600C with an exposure from 1 to 6 hours was evaluated. It was found that high-modulus fibers burn out slower than high-strength fibers. The surface of the fibers in the initial state and after annealing was investigated. Composite samples with an Al-6Mg alloy matrix reinforced with these types of carbon fibers were tested for three-point bending. It was found that the strength of the composite with high-modulus fiber was more than two times higher than strength of the composite with high-strength fiber. Carbon fibers extracted from CF/Al composites and the fracture surface of composites samples after mechanical tests were investigated.

Abstract Here we investigate the reaction of solvothermal decomposition of the copper salt of N,N-dinitrourea in the synthesis of nanoscale copper (II) oxide. The developed method for preparing the nanopowder is of interest due to the increasing demand for nanoscale copper (II) oxide in various industries. This study examines the temperature gradient effect on the reaction rate and measures effective (observed) rate constants for thermal decomposition of the N,N-dinitrourea copper salt in N,N-dimethylformamide (DMFA), and justifies the optimality of the chosen temperature in this method for preparing nanoscale copper (II) oxide. The reaction rate was controlled every 15 min by UV-visible spectrophotometry at 760 nm immediately after the reactants were mixed.

Образование радиационных дефектов приводит к изменению электрофизических, оптических и других свойств полупроводниковых приборов. Моделирование этого процесса с учетом неравновесного состояния электронной подсистемы является актуальной задачей, не получившей завершенного решения в настоящее время. В работе на основе численного моделирования проанализировано влияние положения в запрещенной зоне квазиуровня Ферми электронов на зависимость линейной скорости генерации междоузельного кремния и дивакансий в кремнии, облученном протонами. Рассчитаны профили распределения междоузельного кремния, вакансий, дивакансий, созданных низкоэнергетическими протонами в кремнии. Из полученных результатов следует, что, если квазиуровень Ферми электронов расположен в верхней четверти запрещенной зоны и приближается ко дну зоны проводимости, то линейная скорость генерации первичных радиационноых дефектов, созданных низкоэнергетическими протонами, уменьшается. Следовательно, в неравновесных условиях, вызванных высоким уровнем освещенности или протеканием электрического тока через n-p переход в режиме прямого электрического смещения, а также в n-области кремния, возможно дифференцировано изменять концентрацию радиационных дефектов при воздействии низкоэнергетическими протонами. Полученные результаты могут найти применение при разработке новых методов модификации свойств полупроводниковых структур.

Abstract The formation of radiation defects leads to a change in the electrophysical, optical, and other properties of semiconductor devices. Modeling this process taking into account the nonequilibrium state of the electronic subsystem is an urgent task that has not yet received a complete solution. Based on numerical simulation, the influence of the position in the band gap of the Fermi quasilevel of electrons on the dependence of the linear generation rate of interstitial silicon and divacancies in silicon irradiated by protons is analyzed. The distribution profiles of interstitial silicon, vacancies, divacancies created by low-energy protons in silicon are calculated. From the obtained results it follows that, if the quasi-Fermi level of electrons is located in the upper quarter of the band gap and approaches the bottom of the conduction band, then the linear rate of generation of primary radiation defects created by low-energy protons decreases. Consequently, under nonequilibrium conditions caused by a high level of illumination or the passage of an electric current through the n-p junction in the forward electric bias mode, as well as in the n-region of silicon, it is possible to differentially vary the concentration of radiation defects when exposed to low-energy protons. The results obtained can find application in the development of new methods for modifying the properties of semiconductor structures.
JUSTICE IN THE SYSTEM OF VALUE FOUNDATIONS OF THE STRATEGIC DEVELOPMENT OF RUSSIAN STATEHOOD
Authors: SVIRIDKINA ELENA V.
Published: October 2024

The article presents the original interpretations of justice related to the consideration of Russia as an independent civilisation with its own identity, origins, values, and goals. The author demonstrates that the understanding of justice as legality, lawfulness, or formal honesty, which has developed within the framework of the Romano-Germanic cultural and historical type, does not correspond to its Russian (Slavonic-Russian) formulation, which is directly connected to mercy, compassion, and love.
