Published: August 2024

The article examines the peculiarities of the functioning of energy market enterprises in conditions of high risk and danger caused by the influence of military operations taking place on the territory of Ukraine. The peculiarities of the functioning of energy market enterprises were highlighted, which are divided into six areas, namely: regulation of prices and tariffs, alternative energy sources, the need to diversify suppliers, the instability of the political and economic situation, the need to introduce energy-efficient technologies, the development of the sales system. It is substantiated that the energy industry’s transformation should take place with a focus on sustainable development and European standards. Therefore, the requirement for enterprises to comply with the norms of energy saving and environmental friendliness of production, which are implemented based on energy-efficient technologies, is updated. The study of the rating of electricity suppliers made it possible to identify industry leaders and outsiders according to the relevant indicators. Based on the analysis, key factors that significantly impact the industry’s investment attractiveness and, depending on the current situation, have the potential to strengthen or weaken energy sector companies as a participant in the investment process. Ways of harmonizing relations between segments of traditional energy generation and renewable energy have been studied. It has been proven that the activity of energy industry enterprises forms the state’s general level of energy security. Factors affecting energy security at the national level are decomposed, including geopolitical, economic, ecological, technological, social, technical, and regulatory determinants. The energy sector’s recovery in the post-war period should be based on new principles and technologies of an innovative and digital nature. The main provisions of the State Energy Security Strategy were analyzed, and directions for achieving the set goals were identified; the main obstacles in implementing the strategic goal of strengthening the potential of energy sector enterprises as subjects of market relations were revealed. Keywords: energy market, energy supply companies, energy industry, energy security, management model, strategic development.
Mindsets and EFL Learner Autonomy in the Digital Era : Secondary School Learners as a Case Study
Authors: Khoudri Insaf
Published: August 2024

EFL learners in Morocco have numerous online resources and tools at their disposal to aid in language learning. Despite this abundance, many learners face challenges in developing learner autonomy and effectively utilizing these digital tools. Mindsets are often attributed to these difficulties and can have a significant impact on success or failure in language learning. The mode of learning to which students are exposed also plays a role. This paper aims to enhance understanding of the relationship between mindset, mode of learning, and learner autonomy in Moroccan EFL education. A self-administered questionnaire was given to two groups of 88 Moroccan Second-year baccalaureate students to investigate whether mindsets or mode of learning affects autonomy in the technological era. The findings demonstrated that the majority of students had mobile phones, but their usage varies. Project-based learners demonstrated a high level of autonomy, with 93% using mobile phones for research and learning instead of social media. Conversely, 20% of teacher-centered learners believed a teacher’s presence is necessary, while all project-based learners considered the teacher’s role important but not always required. The study highlighted the importance of mindset and mode of learning in developing learner autonomy and the potential benefits of project-based learning for language learners.

Purpose - The study aimed to determine the effect of CEO gender variables, CEO age, as well as CEO gender reassignment on tax aggressiveness. Taxes are one of the burdens for companies that will reduce the company's profits. A company tends to do tax evasion to reduce its tax burden through a variety of means. Thus, companies are becoming more aggressive towards taxes. Tax aggressiveness is an action taken by companies to engineer taxable income through tax planning in a legal (tax avoidance) or illegal (tax evasion). Research Method - This research is applied with cross sectional and time series methods. The technique used in sampling data in this study is purposive sampling. This method is done by selecting a research sample through certain considerations or criteria, based on the purpose of the research. The sample population in this study is the annual report and financial statements of manufacturing companies listed on the Indonesia Stock Exchange that have been audited in 2017 to 2020 with a total of 193 companies. Information about the annual report data and financial statements is obtained from the site contained on the Indonesia Stock Exchange, namely www.idx.co.id. Findings - The research results of CEO gender and CEO age have no effect on tax avoidance as proxied by the effective tax rate. This shows that gender differences and the increasing age of a company's CEO do not influence the occurrence of tax aggressiveness in a company. There are several control variables that are considered to have a significant positive influence on tax aggressiveness

Published: August 2024

Goal programming (GP) is a well-known multi-criteria decision-making tool that is supported by a network of practitioners and researchers who aim to develop its mathematical foundation to cover a wide range of applications. The popularity of GP models stems from their structure, which is based on a satisfying philosophy. This philosophy takes into consideration the preferences of the decision-maker concerning the model parameters. Therefore, the GP model provides the decision-maker with one satisfactory solution that reflects the trade-off between competing objectives. Nevertheless, there is no guarantee regarding the efficiency of this solution. Consequently, this study is designed to improve the quality of decision-making processes by addressing the efficiency issue with the solutions of GP models. The main contribution of this paper is to improve the mathematical framework of the GP model so that it can generate a set of Pareto optimal solutions rather than just one solution. This allows stakeholders to have a complete picture of the feasible space of solutions and select the solution that represents the best compromise according to their preferences. As a result, the proposed methodology is called generational GP. In addition, the study enhances the quality of GP solutions by integrating the notion of the hypervolume subset selection problem with the suggested technique. This, in turn, overcomes the efficiency problem of GP solutions. The performance of the proposed method has been validated through an application to the flow shop scheduling problem. However, our modeling approach is useful for decision-makers in different fields of study. Finally, the merits of the generational GP method are highlighted, with a strong emphasis on potential areas for future research.

The Importance of Trade Unions / Labor Unions in Companies
Authors: Ahmadi  , Moh Abu Mahmud
Published: August 2024

An employment relationship occurs if there are elements of orders, wages, work carried out between the employer and the worker/laborer. Once there is an employment relationship, workers/laborers have the right to establish a workers/labor union within the Company. After workers/laborers have a trade union/labor union organization in the company, the worker/labor union has rights that must be accepted by the company in order to achieve dynamic work relations within the company. The rights of workers/labor unions that must be accepted after being established in a company are; represent workers/laborers to negotiate with employers, make collective work agreements, fight for share ownership for workers/laborers in the company and fight for the rights of every worker/laborer as regulated in labor legislation. Employers should not be arbitrary in providing every right to workers/laborers in the company because the rights of every worker have been regulated in legislation, for example regarding the Regency Minimum Wage (UMK) which has been regulated by the Governor's Regulation. Every company must comply with it to pay wages for its employees according to the UMK. . UMK is a safety net for workers to earn wages in order to achieve peace of mind at work. Even though wages are determined every year, if employers want to pay above the minimum wage, it is also permissible because workers/laborers are company assets that need to be looked after in order to make the production process more productive. But sometimes entrepreneurs underestimate workers/laborers because there are many workers out there who are unemployed, so between support and demand, supply and demand are not balanced, the bargaining position of workers/laborers is very low. So, to protect workers/laborers, it is absolutely necessary to have a workers/labor union in the company to act as a representative in every industrial relationship with the employer. One of the roles of trade unions is to represent workers/laborers when facing employers' lawsuits, whether regarding employment disputes or other disputes. One of the dispute claims that is submitted must be carried out by bipartite efforts first between the worker/laborer and the employer after which mediation is carried out by the department that handles employment issues.

The times provide mandatory demands for laws in Indonesia to develop in accordance with the needs of today's society. However, in reality there are still many rules that intersect with each other and cause legal uncertainty. To deal with this, Indonesian law must be ready to adjust to the renewal of the legal system through omnibus law due to the accumulation of regulations. This research aims to open a new perspective in the implementation of omnibus law on land regulations that have been overlapping, resulting in the absence of legal harmonization. The research method is conducted with a normative juridical approach. The type of approach used is the statute approach. The legal materials used are primary legal materials, secondary legal materials, and tertiary legal materials. Data collection techniques are carried out by means of literature studies related to research both from laws, scientific works and books. The results of this study indicate that the implementation of the omnibus law is a solution to the overlapping land regulations in Indonesia which must be accompanied by synergy and coordination from various institutions in order to create legal certainty.

Work requires energy that source from food in order to maintain body’s immune system, so the body does not get tired quickly and increases work productivity. To increase work productivity is by looking at the workload that workers get. The workload given to workers needs to be adjusted to the psychological and physical abilities of workers which influence work health conditions in general and work fatigue in particular. This study aims to determine the relationship between food intake and work fatigue with labor productivity at the rambak cracker production site in the Pegandon sub-district, Kendal Regency. This research is using a cross sectional approach method. The total respondents in this study were 30 workers who were taken using saturated sampling or total sampling. The results of the study showed that food intake was good, namely 90% of respondents had good energy intake, 90% of respondents had good protein intake, 86.7% of respondents had good fat intake, and 63.3% of respondents had good carbohydrate intake. Based on the p value, it can be concluded that there is no significant relationship between the food intake variable and work productivity. Most respondents (96.7%) had low levels of work fatigue, and most respondents (66.7%) had good productivity. It is known that the p value of energy intake is 1,000, protein intake is p=0.068, workers' fat intake is p=0.110, carbohydrate intake is p=0.293. work fatigue analysis with shows the p value = 0.309 (p > 0.05), so it is concluded that there is no significant relationship between work fatigue and productivity of workers in rambak cracker production businesses in Pegandon sub-district, Kendal Regency.

Introduction The optimization of diagnostic quality is a major issue in Pathological Anatomy and Cytology (ACP) to secure analytical circuits and protect the operational flow of histological analyses and molecular biology examinations. The objective of this work is to validate the analytical performance of standard hematoxylin-eosin (H.E) staining according to the evaluation criteria of slides in the laboratory.  Materials and Methods Method validation involves numerous steps requiring close collaboration between pathologists and technicians. For our study, the validation covered performances such as inter-technician variability, inter- pathologist variability, and inter-block contamination. The study included 4 paraffin-embedded blocks from 2 surgical specimens, each block being sectioned by 4 different technicians on 4 different microtomes. The 16 obtained sections were stained and read by 2 expert pathologists.  Results Across the 7 evaluation criteria, a preliminary concordance of 98 % was generally found, with no differences impacting the diagnosis.  Conclusion The process of qualitative method validation in ACP is complex due to the multiplicity of stakeholders, the presence of several sub-processes, the difficulty in managing interfaces, and the desire to align with current regulations as a reference site (ISO 20166-4/2021 standard).4. Nevertheless, it is necessary within a quality assurance approach.

Published: August 2024

Untreated diabetic retinopathy, a complication of uncontrolled diabetes, may lead to total blindness if not addressed promptly. Consequently, in order to avoid the serious complications of diabetic retinopathy, it is crucial to diagnose the condition early and treat it medically. Patients go through a lot of pain and suffering as ophthalmologists manually identify diabetic retinopathy. With the use of an automated method, diabetic retinopathy may be detected more rapidly, allowing for easier follow-up therapy to prevent more eye damage. This paper presents a machine learning strategy for feature extraction including exudates, hemorrhages, and micro aneurysms. The strategy involves a hybrid classifier that integrates support vector machine, k closest neighbour, random forest, logistic regression, and multilayer perceptron networks. To further assist in DR stage image recognition, for instance to detect blood vessels, future research may center on applying object identification techniques based on convolutional neural networks (CNNs).

Background and Aim Investigates the presence of relationship between preferred decorations, colored walls, and nurse’s uniform to hospital anxiety of 150 pediatric patients admitted in the pediatric ward of Geregorio T. Lluch Memorial Hospital in Iligan City, Philippines.  Design The researchers utilized a cross-sectional correlational approach to explore probable associations between the variables and hospital anxiety, giving an insight into factors that are likely to affect hospital anxiety among the patients.  Results Key findings include a strong preference for ward decorations with themes. Among hobby spaces, crafting area had the highest number of likes. All colors were preferred for colored walls except for black, brown and burgundy. Having no wall art/mural, no natural elements in the decorations, and no decorations in ward rooms were disliked or not preferred. Themed wall mural, and gray and blue colored walls have significant relationship to hospital anxiety. There is also a significant relationship between stripes as nurses’ uniform design and peach orange as a uniform color, and hospital anxiety.  Conclusion The overall finding was that most pediatric patients experienced similar levels of anxiety regardless of their preferences for decorations, colored walls, or nurses’ uniforms. This imply that while children have varied preferences in terms of the hospital environment, these preferences influence their hospital anxiety levels during hospital stays.
The Influence of Parenting Democratic Parenting and Self-Efficacy on Interest in Learning Through Emotional Intelligence in 2nd Grade Students of Eskola Secundaria Geral "99" Atauro Timor Leste

Published: August 2024

This study aims to explore the impact of democratic parenting styles and self-efficacy on students' learning interest through emotional intelligence as a mediating variable at Eskola Secundaria Geral "99" Atauro, Timor Leste. The research employs a descriptive quantitative approach, involving all second-grade students as the sample using total sampling technique. Data were collected through questionnaires measuring democratic parenting styles, self-efficacy, emotional intelligence, and learning interest. Data analysis was performed using path analysis with JASP version 19.0, including validity, reliability, and normality tests to ensure data quality. The findings indicate that democratic parenting styles have a positive and significant effect on students' emotional intelligence. Self-efficacy also has a positive and significant effect on emotional intelligence. Furthermore, both democratic parenting styles and self-efficacy directly influence students' learning interest, while emotional intelligence positively and significantly affects learning interest. However, emotional intelligence does not serve as a significant mediating variable in the relationship between democratic parenting styles and learning interest, nor does it mediate the relationship between self-efficacy and learning interest. These findings suggest that democratic parenting styles and self-efficacy have a direct impact on students' learning interest, while emotional intelligence plays a role in enhancing learning interest without acting as a mediator.

Published: August 2024

The utilization of waste vegetable oil (WVO) in bitumen has been a subject of research for an extended period, yet its application in crumb rubber-modified bitumen (CRMB) has not been thoroughly documented. In this study, blends incorporating varying proportions of WVO (5-20% wt) and crumb rubber (CR) were formulated, and the physical, chemical, and rheological properties of the WVO-CRMB blend were systematically examined. Essential physical tests, encompassing penetration, specific gravity, softening point, flash point, and viscosity, were conducted, along with chemical analyses (FTIR), including SARA composition. Rheological assessments were performed using Dynamic Shear Rheometer (DSR) and Bending Beam Rheometer (BBR). The findings revealed an upswing in penetration, increasing from 48.2 at 20% CR content to 67.61 with a 10% addition of WVO to 20% CR bitumen, coupled with a decline in softening point from 62.35°C to 37.51°C. Additionally, SARA composition tests indicated that WVO led to a reduction in asphaltene content and the colloidal stability index of CRMB, decreasing from 0.71 at 20% CR content to 0.55 with a 20% addition of WVO to 20% CR bitumen. Rheological analyses demonstrated enhanced rutting and fatigue resistance, particularly in high-temperature deformation resistance. The rutting (G*/sinσ) and fatigue (G*.sinσ) parameters exhibited improvement from 2.33 at 20% CR to 2.91 with a 20% addition of WVO to 20% CR bitumen at an elevated temperature of 76°C. These advancements in physical, chemical, and rheological properties suggest that incorporating WVO into CRMB enhances the overall performance of the bitumen. This modification holds promise for alleviating pavement distress and enhancing the overall performance and longevity of highway pavements.

The conceptualization of the process of making marketing-based regional destination strategy. Framework of its development and implementation based on the successful case of the Novgorod region — a frontier land in the north-west of Russia. The challenges for the destination are typical for many Russian regions: strong tourist seasonality, poorly differentiated domestic and incoming tourist flow, limited marketing budgets. The case was analyzed and presented as the model approach. The empirical basis of the research within the framework of the author’s approach to the development of a regional tourism strategy in the paradigm of holistic marketing was a qualitative and quantitative analysis of the dynamics of indicators of tourist activity in the region both on the eve of the adoption of the strategy and according to the results of its implementation. The effectiveness of the flexible planning combining tough OCR and soft tool mix (fast response marketing) was unveiled. In details was demonstrated how the tourism strategy takes into account the existing potential of the region, estimated potential of the creating artificial attractions, launching of a brand new tourism products, consolidation and coordination activities of the tourism development institutions, authorities and business. A holistic approach means: structuring and analyzing all marketing elements of the regional tourism system; selection of projects according to the goals and resources; positioning of the destination in accordance with the preferences of key target segments; coordination and joint work with local authorities to promote the place in different markets; attracting investors. The stereotype about finance intensity as the compulsory condition of the effective marketing was redefined through the new AR promo instruments. The process of structuring the elements of regional tourism is presented in the form of separate blocks interconnected within the framework of the strategy: marketing (market research and predictive analytics; promotional — aimed at tourists, facilitating — aimed at residents), infrastructure, management of the tourism sector; community of tourism actors in the region and beyond. The flexible concept of scientific and methodological support of strategizing regional tourism sector is presented.

The methane seeps on the Pacific margin of Costa Rica support extensive animal diversity and offer insights into deep-sea biogeography and phylogeography. During five expeditions between 2009 and 2019, we conducted intensive faunal sampling via 63 submersible dives to 11 localities at depths of 300-3600 m. Based on these expeditions and published literature, we compiled voucher specimens, images, and 267 newly published DNA sequences to present a taxonomic inventory of macrofaunal and megafaunal diversity with a focus on invertebrates. We identified 487 morphospecies, of which 132 are described species, at least 57 are undescribed species, and the remainder include some degree of taxonomic uncertainty, likely representing additional undescribed species. This total represents the highest number of distinct morphospecies published from a single seep or vent region to date. Of the described species, 38 are known only from the Costa Rica seeps. We also report 13 range extensions for species known from Mexico, the Galápagos seamounts, Chile, and the western Pacific; 17 new depth records; and three new seep records for species known to occur at vents or organic falls. We note that no single evolutionary narrative explains the patterns of biodiversity at these seeps, as even morphologically indistinguishable species can show different phylogeographic affinities, biogeographic ranges, or depth restrictions. We emphasize the value of careful molecular taxonomy and comprehensive specimen-based regional inventories for biodiversity research and monitoring.
Bibliometric Analysis of Predictors of Altmetric Attention Scores in Orthopedic Research: Investigating Online Visibility

Published: August 2024

Background

Altmetric Attention Score (AAS) captures online attention received by a research article in addition to traditional bibliometrics. We present a comprehensive bibliometric analysis of high AAS articles and identify predictors of AAS in orthopedics.

Materials and Methods

The top 30 articles with highest AAS were selected from orthopedic journals using the Dimensions App. Multilevel mixed-effects linear regression was used to address clustering in articles from the same journal, with journals as the leveling variable.

Results

A total of 750 articles from 25 journals were included. In the final multivariable model, the funding source (none, industry, government, foundation, university, or multiple), findings (positive, negative, neutral, or not applicable), and the journal's impact factor were significant at
P
<.05.

Conclusion

Predictors of AAS are similar to predictors of traditional bibliometrics. Future studies need prospective dynamic data to further elucidate the AAS. [

Relationships Among Internalized Stigma, Readiness to Change and Treatment Eagerness, and Recovery Among Individuals With Substance Use Disorder in Turkey
Authors: Ayhan Cemile Hurrem , Aktaş Mehmet Cihad , Aktaş Sakine , Aslan Kadriye
Published: August 2024

Purpose

To investigate relationships among internalized stigma, readiness to change and treatment eagerness, and recovery among people with substance use disorder (SUD) (
N
= 131).

Method

This study used a cross-sectional and correlational research design. Multiple linear regression was used for analysis.

Results

A 1-unit increase in alienation and discrimination experiences led to 0.220- and 0.337-unit increases in readiness to change and treatment eagerness, respectively (
p
= 0.001); however, a 1-unit increase in stigma resistance led to a 0.306-unit decrease in recovery (
p
< 0.001). There was a negative correlation between internalized stigma and recovery and positive correlations between internalized stigma and readiness to change and treatment eagerness; however, there was no significant relationship between recovery and readiness to change and treatment eagerness.

Conclusion

Early intervention programs targeting internalized stigma in individuals with SUD may improve readiness to change and treatment eagerness and recovery attitudes. [

White Supremacism and Global Colonial Continuities
Authors: Rusero Alexander Madanha , Nyakatungure Moses
Published: August 2024

This chapter examines why decolonising knowledge production remains necessary to confront white supremacy in Africa. It is a truism that Africa's epistemic landscape remains entrapped within the undertones of white supremacist logic even as the continent now boasts of almost 70 years after the first African states' attainment of independence from colonial rule. Africans must begin to question the efficacy of the erstwhile colonisers' education system in pushing for Africa's development. Africa's epistemological foundations remain deliberately positioned to sustain white supremacy perennially. The epistemological landscape is one characterised by discrimination and marginalisation of African epistemology. This chapter is a deliberate modest attempt to expose the fallacy of white supremacy and burst the myths of the global colonial continuities attempting to sustain a Eurocentric normative epistemological landscape.

In the current era, several machine learning algorithms play a major role in supporting e-commerce security by offering a practical approach to detecting and mitigating threats. These techniques and methods provide a clear analysis of vast amounts of transactional data to identify suspicious activities and patterns indicative of fraud. Techniques such as anomaly detection, clustering, and classification help in real-time threat identification and response. Over the years we have seen a boom in e-commerce where people are moving to online shopping for their regular stuff. However, it also means the drastic rise of e-commerce fraud and hacking. The main purpose of selecting machine learning algorithms is that it can learn from data and use this learned knowledge for predicting new examples or making decisions. This chapter gives clear ideas and best practices approaches on machine learning algorithms for e-commerce on security aspects. These algorithms used in machine learning models help identify and detect fraud access systems, personalized security measures, and automated threat response mechanisms.
