ELECTORAL ADMINISTRATION IN NIGERIA: THE CONFLICTS, PROBLEMS, AND PROSPECTS
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Saka Moshood , Sesa Leonard
Published: July 2024

This article investigates the electoral administration in Nigeria, focusing on conflicts and problems in the Fourth Republic. Nigeria’s transition to democracy in 1999 involved the crucial role of the Independent National Electoral Commission (INEC). The study aims to highlight that both international and local electoral observers have reported deficiencies in the initial elections conducted by INEC, which have had negative impacts on democracy in Nigeria. Additionally, the article discusses how an incumbent political party may collaborate with INEC to manipulate election results in their favor. Consequently, INEC has faced accusations from opposition parties after announcing electoral outcomes. The article argues that INEC has not maintained political independence in managing elections in Nigeria and suggests that INEC should be more powerful than the incumbent government. The study utilized qualitative and primary documents as its research methods.
Post-Pandemic Financial Literacy in social media: How microblog posts reflect Ctizens’ Opinions about Taxes
Authors: Berdasco-Gancedo Yolanda
Published: July 2024

The global pandemic has been used to justify many public policy decisions, including those concerning the economy and public spending. Making payments with taxpayers’ money for public health and social welfare is understandable, as long as it is done to address a global emergency. However, once the disease data gives way to a stable state, it is necessary to understand how the public evaluates the management of tax revenue and analyze the impressions communicated about taxes, the tax system, and spending. To this end, a highly qualitative methodology based on critical discourse analysis was used to study messages posted on Twitter (now X) in August and September 2022. The results will confirm whether economic knowledge is still as limited in digital media and social networks as in traditional media.
Media literacy in moroccan schools: An analysis of student awareness, teacher understandings and textbook content
Authors: Mliless Mohamed , Boulaid Fouad
Published: July 2024

This study examines the state of media literacy in Morocco by employing a multimethod approach. To that end, we used a questionnaire to assess students’ (N = 700) awareness of the media literacy, an interview to gather teachers’ (N = 40) perspectives on the concept of media literacy in the educational domain, and content analysis to examine the concept’s availability in textbooks (N = 28) used to teach Arabic, French, and English in primary, middle and high schools. The results show that students know little about the concept, are not well-versed in media literacy, and use various media outlets without being critically briefed on their risks. Meanwhile, teachers recognize the importance of media literacy in assisting students in deconstructing media messages and identifying fake news and misinformation. To be successful in teaching media literacy, teachers postulate that they need to be well-trained and develop a professional attitude to media literacy in order to ensure a coherent and efficient implementation of the concept, and for this, they call for pedagogical materials. The results show that the pedagogical resources under study did not include courses, activities, or separate units on media literacy. Instead, the pedagogical material contained isolated and relegated lessons on the functions and effects of media and information technologies. We believe that three obstacles prevent media literacy integration in Morocco: students’ lack of awareness, teachers’ lack of professional development, and insufficient school pedagogical support.
Do fake news catch our attention? A study of visual attention applied to the consumption of fake news about COVID-19 in Brazil
Authors: Rógora Kawano Diogo , Nunes Severino Tiago
Published: July 2024

The development of technologies aimed at people’s daily communication allows for greater access to information. However, much of this content is the result of disinformation campaigns. Despite efforts to combat fake news, how people read content to identify false messages and make decisions is still not well understood. This study aims to use eye-tracking technology to identify and understand differences in the reading patterns of fake news and real/authentic news sources. Therefore, an experiment was conducted with 23 participants, who had their ocular behavior data measured while watching two types of content in the Brazilian scenario: real news and artificially produced news (fake news). The main results suggest differences and similarities in the way that people read and pay attention to content elements, such as headlines, main text, images, and news sources. The importance of using eye tracking in new studies aimed at combating disinformation is verified.

Published: July 2024

The study aimed to examine the influence of user-education programmes on the information and study skills and competencies of first-year students at North–West University, Vaal Triangle Campus (VTC), in South Africa. The study adopted a quantitative approach and employed the case study method. The respondents consisted of 1,885 first-year students across two faculties with a sample size of 320, which were selected using the systematic sampling technique. The self-developed questionnaire was then distributed among the respondents. Out of 320, 266 students responded to the questionnaire, which produced a good response rate of 83%. The collected data were analysed using frequency and percentages and presented in tables and charts. The results revealed that a substantive number of first-year students never attended training on library use, including high school, public, college or any other academic libraries, prior to their arrival at the university. However, after attending the user-education programmes, they became independent users of the library and its resources, which was of great importance to lifelong learning and, thus, increased the usefulness of the library.

Minimal Inclusions of C*-algebras of Groupoids
Authors:   , Wright Shonaugh
Published: July 2024

A non-degenerate inclusion of C*-algebras B ⊂ A is considered minimal if the only fully normalised ideals are trivial. An ideal is fully normalised if the set of normalisers of B are contained in the set of normalisers of the ideal. We begin by considering when the inclusions C₀(G⁽⁰⁾) ⊂ Cᵣ*(G) and C₀(G⁽⁰⁾) ⊂ C*(G) are minimal inclusions for an étale groupoid G. Then we consider étale groupoids graded by a cocycle c: G → Γ for a discrete group Γ, writing Gₑ for the identity-graded subgroupoid. We investigate the inclusions Cᵣ*(Gₑ) ⊂ Cᵣ*(G) and C*(Gₑ) ⊂ C*(G) of groupoid C*-algebras. We give conditions on the groupoids G and Gₑ under which the inclusions are minimal.

We generalise these results by considering non-degenerate inclusions of twisted groupoid C*-algebras and graded twisted groupoid C*-algebras. We finds conditions on G (and Gₑ for the twisted graded inclusion), which make the inclusions minimal. We conclude by applying our results to higher rank-graphs. In their 2020 paper Crytser and Nagy found simplicity criteria for the ambient C*-algebras depending on the type of inclusion. We use this criteria to show how some of our results align literature results.

Authors: Gao Junxi , Hui Congcong , Liu Junru
Published: July 2024

Residents constitute the principal elements of regional tourism development, and their behavioral cognition will play a certain role in promoting local tourism development. In recent years, although tourism along the Sichuan–Tibet Line (318 and 317 routes) has made some progress, there are some problems, such as homogenization of products, a single local culture, and inconspicuous brand characteristics. At the same time, due to the remote geographical location, living conditions, health conditions, and other imperfections, resulting in greater constraints on tourism development. This article employs Letong Ancient Town as a representative case study, and discusses the impact of tourism development on the local economy, environment, society, and culture from the perspective of residents’ perception through field research and data analysis, thereby providing a reference for regional tourism development.

Authors: Tan Yinqiu , Kong Xia , Chen Yanli
Published: July 2024

Objective: To revise the self-rating scale of systemic family dynamics (SSFD) based on its applicability among college students in southwest China. Methods: The study conducted a survey using the Chinese version of the self-rating scale of systemic family dynamics (SSFD) and the Center for Epidemiological Studies depression scale (CES-D) on 3,122 college students from Sichuan, Chongqing, and Guizhou. Exploratory factor analysis was performed on the items of SSFD by SPSS, followed by confirmatory factor analysis by Amos. Results: Based on the factor analysis, the systemic logic dimension of the original scale was removed, retaining three dimensions: family atmosphere, individualization, and disease concepts. The number of items was reduced from 23 to 14. The revised scale’s overall Cronbach’s alpha was 0.914, with dimension-specific Cronbach’s alpha ranging from 0.689 to 0.905. All dimensions and the total score of the revised SSFD showed significant negative correlations with depression (-0.193**, -0.237**, -0.086**, -0.168**). The confirmatory factor analysis showed good fit indices (GFI = 0.943, IFI = 0.950, CFI = 0.950, NFI = 0.944, RMSEA = 0.069, SMRA = 0.037). Conclusion: The revised SISFD scale features a clear structure and meets measurement standards, making it suitable for measuring systemic family dynamics among southwest China college students.

Published: July 2024

An analysis of the literature data showed unidirectional trends in the risks of developing cardiovascular pathology associated with depression, as well as a significant prevalence of factors of psycho-emotional stress, in particular depression, mainly in female populations. It has been shown that such trends are probably related both to the physiological characteristics of the female body and to variations in the expression of depression/major depression, which in turn affect cardiovascular risks. In accordance with this paradigm, to improve the prevention of cardio-vascular diseases (CVD) in various regions, it is necessary to create an infrastructure that can ensure the availability of information and educational technologies and appropriate advice on identifying and monitoring psychosocial risk factors (PRF) for all categories of the population, depending on regional characteristics.

Aim: To assess erythrocyte membranes β-adrenoreactivity and heart rate variability (HRV) in children with supraventricular arrhythmias initially and in the early period after radiofrequency ablation (RFA).

Study method. The study included 43 patients 13 [10; 15] years with supraventricular arrhythmias and indications for interventional treatment. The patients were divided into groups depending on the electrophysiological variant of the arrhythmias: manifest Wolf-Parkinson-White (WPW) phenomenon – 15 patients; latent and manifest WPW syndrome – 13 patients; atrioventricular nodal reentry tachycardia (AVNRT) – 10 patients; atrial ectopic tachycardia – 5 patients. The control group consisted of 11 practically healthy children 14 [12; 16] years. The patients underwent RFA. Initially and in 3–5 days after RFA, the following was performed: HRV time analysis according to Holter monitoring ECG; determination of erythrocyte membranes β-adrenoreactivity in blood samples.

Results. In all groups, initially and in 3–5 days after RFA, the median level of erythrocyte membranes β-adrenoreactivity remained within the normal range; no statistically significant changes in the indicator were detected, including when compared with the control group. Analyzing HRV in patients with the WPW phenomenon and syndrome, pNN50 and rMSSD values decreased statistically significantly after RFA, p = 0.004, p = 0.047, respectively. In patients with AVNRT, the level of SDANNi increased statistically significantly, p = 0.007. The changes indicate a decrease in the influence of the vagus nerve and an increase in sympathetic influences, which is regarded as a decrease in HRV.

Conclusion. Supraventricular arrhythmias in children with structurally normal hearts are not accompanied by dysfunction of the autonomic nervous system (ANS) according to the analysis of erythrocyte membranes β-adrenoreactivity and HRV, which indicates the absence of a significant contribution of the ANS to the pathogenesis of these arrhythmias. In the early postoperative period after RFA, a decrease in HRV was noted, associated with manifestations of operational stress. The lack of dynamics in the erythrocyte membranes β-adrenoreactivity level after RFA indicates that in this category of patients HRV indicators respond faster. The study results suggest the value of HRV assessment in patients with supraventricular arrhythmias, while the use of erythrocyte membranes β-adrenoreactivity is more promising in patients with ventricular arrhythmias in whom HRV analysis is limited.

The strategy of scientific and technological development of the Russian Federation prioritizes the formation of new approaches to the treatment of tuberculosis, including forms with multidrug resistance. In modern conditions the fulfillment of this task is impossible without the intensive introduction of advanced digital and intelligent technologies, robotic systems and systems using artificial intelligence methods. This approach should start with an important component –the creation of a knowledge base.

Aim: To create a knowledge base of drug therapy based on the appropriate ontology, to assemble a prototype of a medical decision support system for managing the treatment of patients with pulmonary tuberculosis.

Material and Methods. Current scientific data and recommendations for the treatment of pulmonary tuberculosis in adults were used, according to clinical recommendations approved by the Ministry of Health of the Russian Federation in 2022. The IACPaaS platform is used to implement the intelligent service.

Results. A knowledge base has been created to manage the treatment of patients with pulmonary tuberculosis, which allows you to structure knowledge about drug therapy of tuberculosis, define concepts, relationships and axioms describing this process. Each element of the ontology includes a complexly structured block of conditions that allows you to describe in a formal presentation the necessary clinical criteria that determine the conditions for creating an intelligent assistant to a phthisiologist.

Conclusion. The generation of the knowledge base will make it possible to switch to personalized medicine through the rational use of anti-tuberculosis drugs, which will reduce the time and improve the effectiveness of tuberculosis treatment.

One of the most common complications of ischemic heart disease is ischemic mitral regurgitation (IMR). About 20% of patients with coronary artery disease suffer from the onset and progression of IMR. It is more often observed in patients who have suffered a myocardial infarction of the inferior wall of the left ventricle (LV). It is known that the presence of mitral regurgitation (MR) reduces patient survival regardless of the presence of ischemic heart disease. The accumulated experience in the field of diagnosis and tactics of surgical treatment of IMR is currently ambiguous, despite many studies being conducted. In particular, such important problems as determining predictors and risk factors for recurrent IMR after surgical treatment, as well as indications for mitral valve intervention and the choice of surgical technique for correcting moderate and borderline IMR remain unresolved. Determining the risk factors for an unfavorable outcome of each specific method of surgical treatment of borderline IMR will help the specialists make the right decision regarding the treatment of this pathology. This literature review shows the full range of modern surgical methods for the treatment of borderline ischemic mitral dysfunction, evaluates the results of the most common isolated and combined operations, analyzes the risk factors for unfavorable outcome in the long-term period after their implementation, and also offers original approaches to the tactics of surgical treatment of IMR.
Production of carbon fibers from Castilla's crude-oil deasphalted bottoms
Authors: Leal Gonzalo , Peñaloza Jhon Iván
Published: July 2024

Obtaining raw materials for the manufacturing of carbon fibers from Castilla's crude-oil deasphalted bottoms was achieved through thermal treatments carried out in inert atmosphere, at temperatures ranging from 573 K to 673 K. The deasphalted bottoms displayed isotropic characteristics. Deasphalted bottoms and thermally-treated fractions were characterized using elemental and thermo-gravimetric analyses; the softening point was also defined. The thermal treatment increases the C/H ratio, which is reflected in the softening temperatures. Thermally-treated fractions showed excellent behavior in the threading process and the obtained fibers were stabilized through air-driven oxidation. Once the fibers were stabilized, they were carbonized in inert atmosphere, at 1073 K and 1273 K. Results showed that when this raw material is processed, it has a performance rating of over 65%, and produces compact, infusible structures that may be classified as general-use carbon fibers.
Comparative analysis of different methods for the extraction of hydrocarbons from industrial wastewaters
Authors: Santa Judith Rocío , Serrano Martín , Stashenko Elena
Published: July 2024

A comparison among four extraction techniques such as: liquid - liquid (LLE) continuous and for lots, solid phase extraction (SPE), solid phase microextraction (SPME) and static headspace (S-HS) was carried out. The main purpose of this research was to determine the highest recovery efficiencies and how reproducible the tests are while varying parameters such as time, extraction technique, type of solvents and others. Chromatographic parameters were optimized in order to carry out the analyses. Hydrocarbon's quantification of residual waters was achieved by using a high-resolution gas chromatography with a gas flame ionization detector (HRGC-FID). Validation of the method was carried out by analyzing real samples taken in different sampling places of the residual waters treatment plant of Ecopetrol - Barrancabermeja. The use of extraction methods that require big solvent quantities and long time for analysis are losing validity day by day. Techniques such as the HS-SPME and static HS, are offered as alternatives for quantifying hydrocarbons. They show total lack of solvents, high sensibility, selectivity and the techniques are reproducible. Solid phase microextration (SPME) and static headspace (static HS) techniques were chosen as the extraction techniques to validate the method in real samples. Both techniques showed similar results for the determination of total hydrocarbons (in the gasoline range).
Continuos treatment of oily sludge at Colombian refineries
Authors: Echeverría Víctor , Monsalve Gladys , Vidales Humberto
Published: July 2024

The Colombian Petroleum Institute -ICP-, the research and development branch of Ecopetrol has developed a unique technological package used to treat oily sludge in a continuous way. The sludge comes from a refinery with a 220 000 barrels of crude per day load, located in the Middle Madgalena River Valley in Colombia. The Technological Package allows for :a) the recovery of the hydrocarbon contained in oily wastes (up to 50%); b) the elimination of the oil contained in solid using a biodegradation process; and, c) the availability of an economically and technically feasible solution to handle oily sludge generated in the refinery. The oily wastes treated in this process come from maintenance of refinery's equipment and also from the physical-chemical separation process at the industrial waste water treatment plant. Oily sludge is a complex system where light and heavy oils, contaminated water and contaminated solids coexist in the form of direct, inverse and multiple emulsions. The comprehensive technological package allows the treatment of oily sludge in a cost-effective way. ICP's Technological package developed includes technologies combining mechanical, thermal, chemical and electrostatic dehydration techniques, and stimulated and intensive bioremediation to decontamination of solids saturated with residual oil. This technological package brings a solution to the old environmental problem caused by the inappropriate final disposal of oily wastes such as storage in ponds, marshes and open pits. Nowadays oily wastes generated are treated in a continuous process that is environmentally friendly and economically profitable.

Authors: OTERO F.
Published: July 2024

This article presents the current status of the use of Artificial Neural Networks (ANNs) in process engineering applications where common mathematical methods do not completely represent the behavior shown by experimental observations, results, and plant operating data. Three examples of the use of ANNs in typical process engineering applications such as prediction of activity in solvent-polymer binary systems, prediction of a surfactant self-diffusion coefficient of micellar systems, and process control and simulation are shown. These examples are important for polymerization applications, enhanced-oil recovery, and automatic process control.

Accelerated learning: penggunaan tipe master dalam pembelajaran teori musik dasar

In fundamental music theory, comprehension of how music works is tested in two ways: textual (terms) and contextual (application), when students do not grasp the content and instead focus on learning. As a result, when students create musical arrangements and composition tasks, they are unable to organise melodic, rhythmic, and harmonic arrangements in a fundamentally and elegantly organised manner. The usage of accelerated learning with the MASTER type is believed to provide a remedy to students' confusion about basic music theory. This study employed a descriptive qualitative method and a case study methodology. The research subjects are first-year students of Tanjungpura University's Performing Arts Education Study Programme (FKIP). In-depth observation and direct interviews provided case descriptions in learning. Source triangulation and interactive model analysis were used to determine data validity. Based on the MASTER type's application in learning fundamental music theory, students have had the most impact when they utilise their minds and bodies, create knowledge, and collaborate with others. This is significant because the foundation for shaping students' skills in the twenty-first century is based on students as learners and the shift from constructivism to behaviourism.
