Authors: Zimova N. S. , Fomin E. V.
Published: March 2024

Relevance. In modern conditions of high competition in the labor market, new forms of work are becoming particularly relevant, in particular, the creation of an HR brand as a tool for maintaining the company's image and attracting employees. The development of digital technologies has allowed companies to use new channels of employer brand formation – digital. However, despite the existing need, the features of their use have not been fully studied. Social networks and career sites as the main platforms for the formation of an employer's brand are rapidly developing and transforming, which requires their comprehensive research.

   The purpose is to identify the features of the use of career sites and social networks as the main digital channels for the formation of an employer's brand.

   Objectives: to reveal the essence and identify the main elements of the employer's brand; to conduct a comparative study of the use of career sites and social networks of four Russian companies: Dodo Pizza, Gulfstream, Chulakov.ru, Exness.

   Methodology. The methodological basis of the study was the work of G. Martin, S. Hat Trick, T. Ambler, S. Burrow. As a technical tool for the study of social networks, the system of multifactorial analysis of social media "Cribrum" was used, the method of content analysis was used in the study of career websites of companies.

   Results. As a result of the study, the authors identified the main components of the HR brand broadcast by digital channels focused on basic and additional values. The analysis of digital channels by selected elements revealed the specifics of their use in the formation of the employer's brand. Career sites to a greater extent broadcast additional values of the company, forming a holistic positive image for the general public, without highlighting the target categories of recruiting. Social networks mainly demonstrate the basic values of the company, their content is more specific, focused on certain categories of recruiting.

   Conclusion. Creating a successful employer brand requires a competent combination of the digital channels considered, taking into account their specifics and the category of recruiting, which will allow HR branding to become a long-term HR strategy for attracting and retaining target groups of employees.
Segmentation of Tree-Like Data Structures and Their Parallel Processing in Authentication Methods Based on Block Coupling Encoding
Authors: Tanygin M O. , Chesnokova A. A.
Published: March 2024

Purpose of reseach. In the tasks of authenticating groups of messages encoded in the mode of chaining blocks, there is a need for the formation and processing of specific tree-like structures. The contents of such structures, in addition to information about the placement of data in the internal memory of the calculators, describes the relative location of messages in the data stream between subscribers of a peer-to-peer network. This information is necessary to isolate a structured set from the entire message stream to the receiver, for which its source is uniquely determined. Using approaches to segmentation of tree structures allows you to parallelize the processes of adding elements to it and searching for areas corresponding to an authentication error.

Methods. The division of the tree structure into areas subject to modification and areas for analysis is based on a metric dynamically formed from message authentication codes – the position of a specific message in a structured set of messages transmitted from the source to the receiver. The value of this metric determines the distance from the root of the tree, which defines the boundary between the two named areas

Results. By isolating the modified and analyzed sections of the tree structure, races of processes implementing independent algorithms for working with it are excluded. The possibility of detecting authentication errors before receiving the last message in a structured set of messages is shown. As a result, there is no need to transmit those group messages that were supposed to be sent after the error was detected. Formulas for estimating the average transmission time of multiple messages with sequential and parallel implementation of procedures for the formation and processing of a tree structure containing descriptors of incoming messages to the receiver are given.

Conclusion. The paper shows that the parallel implementation of algorithms for adding elements to the tree structure and the algorithm for searching for areas corresponding to an error reduces the average transmission time of a group of messages by 5-12% compared with the sequential implementation of these algorithms. This reduces the load on the communication channel for the target class of systems using block coupling encoding for authentication.
On Text Understanding Modeling by Means of Artificial Intelligence Systems
Authors: Kruzhilina T. V.
Published: March 2024

Purpose of reseach is to conduct a comparative analysis of texts generated by an artificial intelligence system in the process of processing source text in natural language and counter texts that are the result of human understanding of the source literary text. 

Methods. To achieve the goal and objectives of the study, the author used an experimental technique to conduct a comparative analysis of the denotational structures of counter texts. Participants in the experiment (7 4th year students of the Faculty of Additional Education “Translator in the field of professional communications”, 3 associate professors of the Department of Foreign Languages of South- West State University) assessed the success of recreating the semantic structure of the text of 10 counter texts of different nature - generated by AI and humans. 

Results. The results of the experiment indicate that the completeness of the semantic content of the generated text does not depend on the structure of the source text. Modern methods of semantic text processing by an AI system make it possible to obtain the output of full-fledged text works created taking into account the rules and norms of natural language.

AI systems successfully recreate the denotational structure of the text and reconstruct the syntactic structure. 

Conclusion. Access to large databases allows you to train a neural network on large text corpora, which results in an increase in the accuracy and variability of the lexical units and constructs used. The accuracy of conveying the semantic content of the text varies. It depends on the degree of text compression - the higher it is, the less accuracy can be, because the neural network is unable to classify denotational connections for relevance to the underlying meaning. The degree of accuracy in conveying semantic content is determined by the success / failure of understanding the deep hidden meaning, which is determined by the understanding of the linguistic and extralinguistic context. The ability to recognize the situation model recreated in the source text is the key to understanding the hidden meaning. The AI system can recreate the surface denotational structure of the text quite correctly and accurately, but is not able to construct a model of the situation at this stage of development.

Authors: Undi G S N V K S N Swamy , Kantikar Rohit
Published: March 2024

Particulate matter (PM) constitutes a significant risk factor for environmental health regarding ambient air quality. An epidemiological investigation has determined that inadequate air quality is associated with the development of lung and cardiovascular diseases, chronic ailments, respiratory infections, and a significant number of fatalities on a global scale. According to the World Health Organization (WHO), the annual mortality rate due to air pollution is around 7 million individuals. The necessity for researching air quality, climate change, and the challenges posed by particulate matter (PM) is widely recognized. While reducing ambient air quality, it is essential to consider the limitations of current technical control methods. This article focuses on developing and implementing advanced technology to mitigate particle pollution in urban environments. The comparison of empirical data and computational simulations has demonstrated the efficacy of utilizing pulsed radio waves to reduce particulate matter. The control technique exhibits a threefold increase in the rate of PM concentration reduction compared to gravity settling. The approach's efficacy was evaluated through controlled trials conducted in controlled chambers and urban environments, demonstrating up to 50% reductions. The validation of the implemented test case results of the control technology was performed using historical data while considering the existence of radio waves. The coagulation process demonstrated and verified the effectiveness of reducing particle matter. The employed methodology has been shown to encourage outcomes concerning mitigating particulate matter contamination within urban and industrial environments.

Using mHealth to Improve Communication in Adult Day Services Around the Needs of People With Dementia: Mixed Methods Assessment of Acceptability and Feasibility (Preprint)
Authors: Zheng Amy , Bergh Marissa , Patel Murali Komal , Sadarangani Tina
Published: March 2024

BACKGROUND

Adult day services (ADS) provide community-based health care for older adults with complex chronic conditions but rely on outdated methods for communicating users’ health information with providers. CareMOBI, a novel mobile health (mHealth) app, was developed to address the need for a technological platform to improve bidirectional information exchange and communication between the ADS setting and providers.

OBJECTIVE

This study aims to examine the feasibility and acceptability of CareMOBI in the ADS setting.

METHODS

A concurrent-triangulation mixed methods design was used, and participants were client-facing ADS staff members, including direct care workers (paid caregivers), nurses, and social workers. Interviews were conducted to describe barriers and facilitators to the adoption of the CareMOBI app. The acceptability of the app was measured using an adapted version of the Technology Acceptance Model questionnaire. Data were integrated into 4 themes as anchors of an informational matrix: ease of use, clinical value, fit within workflow, and likelihood of adoption.

RESULTS

A mix of ADS staff (N=22) participated in the study. Participants reported high levels of acceptability across the 4 domains. Qualitative findings corroborated the questionnaire results; participants viewed the app as useful and were likely to implement CareMOBI in their practice. However, participants expressed a need for proper training and technical support throughout the implementation process.

CONCLUSIONS

The CareMOBI app has the potential to improve care management in the ADS setting by promoting effective communication through an easy-to-use and portable method. While the integration of CareMOBI is acceptable and feasible, developing role-specific training modules and technical assistance programs is imperative for successful implementation within the ADS setting.
Predictors of Digital Skills and their Impact on Active Aging and Subjective Health Status in Rural Older Adults in Korea: Cross-Sectional Study (Preprint)
Authors: Lee Hocheol
Published: March 2024

BACKGROUND

The Korean government announced several policies focusing on addressing the social issues arising from the digital divide among older adults. As digital literacy encompasses a range of skills from basic to advanced and is influenced by the surrounding environment, it is necessary to measure these competencies and identify the factors influencing them.

OBJECTIVE

This cross-sectional study aimed to examine the relationships between digital skills, active aging, and subjective health status and to identify predictors of active aging and subjective health status.

METHODS

Data were collected from February 13 to 24, 2023. A total of 422 participants were included in the final analysis. This study used an independent t-test, F-test, Pearson correlation analysis, and multiple linear regression to analyze the collected data.

RESULTS

In the multiple linear regression model with subjective health status as the dependent variable, age, education level, income, and communication were significant predictors.

CONCLUSIONS

The findings of this study indicate that digital skills in older adults are significantly associated with social activities and subjective health status. Conversely, digital addiction among older adults may lead to reduced social activity and adversely affect their subjective health. It is imperative that social workers recognize these cases and devise appropriate measures. With the growing utilization of digital devices among older adults, many obtain health information through online sources. Thus, health education focusing on discerning the reliability of information must be provided to older adults.
Toward Safe and Confident Silver Drivers: Interview Study Investigating Older Adults’ Driving Practices (Preprint)
Authors: Kim Sunyoung , Sivangula Phaneendra
Published: March 2024

BACKGROUND

As the aging population in the United States continues to increase rapidly, preserving the mobility and independence of older adults becomes increasingly critical for enabling aging in place successfully. While personal vehicular transport remains a popular choice among this demographic due to its provision of independence and control over their lives, age-related changes may heighten the risk of common driving errors and diminish driving abilities.

OBJECTIVE

This study aims to investigate the driving practices of older adults and their efforts to maintain safe and confident driving habits. Specifically, we sought to identify the factors that positively and negatively influence older adults’ driving performance and confidence, as well as the existing efforts put into sustaining their driving abilities.

METHODS

We recruited 20 adults aged ≥65 years who remained active drivers during the recruitment from the greater New York area. Then, we conducted semistructured interviews with them to examine their perceptions, needs, and challenges regarding safe and confident driving.

RESULTS

Our findings uncovered a notable disparity between older adults’ self-perceived driving skills and the challenges they face, particularly caused by age-related limitations and health conditions such as vision and memory declines and medication routines. Drawing on these findings, we proposed strategies to bridge this gap and empower older adults to drive safely and confidently, including fostering a realistic understanding of their capabilities, encouraging open dialogue regarding their driving, encouraging regular assessments, and increasing awareness of available resources.

CONCLUSIONS

This study uncovered a noticeable disparity between the perceived driving competence of older adults and the actual challenges they confront while driving. This divergence underscores a significant need for better support beyond the existing aid available to preserve older adults’ driving skills. We hope that our recommendations will offer valuable insights for practitioners and scholars committed to enhancing the overall well-being and quality of life for older adults as they age in their homes.
Relationships of Short video use and insomnia symptoms among rural adults: A perspective on the mediating role of depression (Preprint)
Authors: Hao Jin , Dong Shiju , Yu Zexuan , Zhang Siqian , Li Jiajia
Published: March 2024

BACKGROUND

About four in ten people globally exhibit symptoms of insomnia. With the proliferation of short video apps in life, their impact on adult insomnia remains under explored.

OBJECTIVE

The purpose of this study was to explore the relationship between short video use, insomnia symptoms, and the mediating role of depression among rural adults in China.

METHODS

A cross-sectional survey was conducted from July to August 2023 in rural Shandong, China. A total of 2931 individuals were included in the analysis. Depression and insomnia symptoms were measured using the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10) and the 8-item Athens Insomnia Scale (AIS-8), respectively. After match the short video users with the non-short video users by Propensity Score Matching method (PSM), the chi-square test and rank sum test were used to explore whether short video use was associated with depression and insomnia symptoms. The Ordinary Least Square method (OLS) was employed to determine this association further after controlling for the confounding factors. The significance of the mediation effect was obtained using a bootstrap approach with SPSS PROCESS macro.

RESULTS

42.17% (1236/2931) of the participants used the short video. A significant negative correlation was found between short video use and insomnia symptoms (β=-.590, P<.05). Depression fully mediated the association between short video use and insomnia symptoms (β=-.120, P>.1). The significance of the indirect accounted for 79.66% of the total variance in insomnia symptoms.

CONCLUSIONS

The present findings reveal that short videos use among adults can alleviate insomnia symptoms through its mediating effect on reducing depression. Thus, the potential benefits of short videos warrant further exploration and amplification, provided that addictive behaviors are avoided.
mHealth Engagement for Antiretroviral Medication Adherence Among People With HIV and Substance Use Disorders: Observational Study (Preprint)
Authors: Mi Ranran Z , Yang Ellie Fan , Tahk Alexander , Tarfa Adati , Cotter Lynne M , Lu Linqi , Yang Sijia , Gustafson Sr David H , Westergaard Ryan , Shah Dhavan
Published: March 2024

BACKGROUND

Despite the increasing popularity of mobile health (mHealth) technologies, little is known about which types of mHealth system engagement might affect the maintenance of antiretroviral therapy among people with HIV and substance use disorders.

OBJECTIVE

This study aimed to use longitudinal and detailed system logs and weekly survey data to test a mediation model, where mHealth engagement indicators were treated as predictors, substance use and confidence in HIV management were treated as joint mediators, and antiretroviral therapy adherence was treated as the outcome. We further distinguished the initiation and intensity of system engagement by mode (expression vs reception) and by communication levels (intraindividual vs dyadic vs network).

METHODS

Tailored for people with HIV living with substance use disorders, the mHealth app was distributed among 208 participants aged >18 years from 2 US health clinics. Supervised by medical professionals, participants received weekly surveys through the app to report their health status and medication adherence data. System use was passively collected through the app, operationalized as transformed click-level data, aggregated weekly, and connected to survey responses with a 7-day lagged window. Using the weekly check-in record provided by participants as the unit of analysis (N=681), linear regression and structure equation models with cluster-robust SEs were used for analyses, controlling within-person autocorrelation and group-level error correlations. Racial groups were examined as moderators in the structure equation models.

RESULTS

We found that (1) intensity, not initiation, of system use; (2) dyadic message expression and reception; and (3) network expression positively predicted medication adherence through joint mediators (substance use and confidence in HIV management). However, intraindividual reception (ie, rereading saved entries for personal motivation) negatively predicts medication adherence through joint mediators. We also found Black participants have distinct usage patterns, suggesting the need to tailor mHealth interventions for this subgroup.

CONCLUSIONS

These findings highlight the importance of considering the intensity of system engagement, rather than initiation alone, when designing mHealth interventions for people with HIV and tailoring these systems to Black communities.

Published: March 2024

BACKGROUND

The transition from traditional handwritten prescriptions to digital prescribing systems represents a significant advancement, with the potential to enhance treatment efficacy, patient safety, and professional communication.

OBJECTIVE

This study examines the impact of this transition within a medical oncology service, assessing the compliance of digital prescriptions with established good practice standards and exploring the associated risks.

METHODS

In this retrospective analysis, we compared handwritten prescriptions from the pre-digital era (January-May 2018) with digital prescriptions (January-May 2021) following the implementation of the electronic prescribing system PandaLab Pro®. The inclusion criteria focused on outpatient oncology treatments, with a clear set of exclusion parameters to ensure a focused study scope. The prescription software was introduced to facilitate prescription uniformity through pre-filled templates, enhancing time efficiency and reproducibility

RESULTS

Our findings, based on a sample size of 260 prescriptions (randomized among 30526 archived prescriptions), indicate a substantial improvement in digital prescriptions' compliance with prescribers and patient details, treatment accuracy, and overall adherence to regulatory standards. Notably, digital formats achieved a remarkable 80.8% accuracy rate in compliance with safety criteria compared with 8.5% for handwritten prescriptions (p<.001). The use of pre-filled prescriptions significantly increased compliance from a safety perspective (56% vs. 96.2%; p<.001) compared to digital prescriptions from scratch.

CONCLUSIONS

The analysis further underscores the advantages of pre-filled digital prescription templates, which significantly improved compliance rates compared with manually filled digital and handwritten prescriptions. Moreover, the study revealed a marked shift in prescribing behaviors, with digital prescriptions tending to be more concise yet more numerous, suggesting an impact on medication management and patient adherence, which warrants further investigation. The study supports the transition to digital prescribing systems in oncology, highlighting enhanced traceability, compliance with health authority standards, and patient safety. The implementation of pre-filled templates supported by pharmacists has emerged as a pivotal factor in this improved process. While acknowledging certain limitations, such as the non-quantitative assessment of time savings and acceptability, this research advocates for the widespread adoption of digital prescriptions and serves as a benchmark for future e-prescription initiatives in France.

User Experiences of and Preferences for Self-Guided Digital Interventions for the Treatment of Mild to Moderate Eating Disorders: Systematic Review and Metasynthesis (Preprint)
Authors: Cheung Lauryn Gar-Mun , Thomas Pamela Carien , Brvar Eva , Rowe Sarah
Published: March 2024

BACKGROUND

Digital interventions typically involve using smartphones or PCs to access online or downloadable self-help and may offer a more accessible and convenient option than face-to-face interventions for some people with mild to moderate eating disorders. They have been shown to substantially reduce eating disorder symptoms, but treatment dropout rates are higher than for face-to-face interventions. We need to understand user experiences and preferences for digital interventions to support the design and development of user-centered digital interventions that are engaging and meet users’ needs.

OBJECTIVE

This study aims to understand user experiences and user preferences for digital interventions that aim to reduce mild to moderate eating disorder symptoms in adults.

METHODS

We conducted a metasynthesis of qualitative studies. We searched 6 databases for published and unpublished literature from 2013 to 2024. We searched for studies conducted in naturalistic or outpatient settings, using primarily unguided digital self-help interventions designed to reduce eating disorder symptoms in adults with mild to moderate eating disorders. We conducted a thematic synthesis using line-by-line coding of the results and findings from each study to generate themes.

RESULTS

A total of 8 studies were included after screening 3695 search results. Overall, 7 metathemes were identified. The identified metathemes included the appeal of digital interventions, role of digital interventions in treatment, value of support in treatment, communication at the right level, importance of engagement, shaping knowledge to improve eating disorder behaviors, and design of the digital intervention. Users had positive experiences with digital interventions and perceived them as helpful for self-reflection and mindfulness. Users found digital interventions to be convenient and flexible and that they fit with their lifestyle. Overall, users noticed reduced eating disorder thoughts and behaviors. However, digital interventions were not generally perceived as a sufficient treatment that could replace traditional face-to-face treatment. Users have individual needs, so an ideal intervention would offer personalized content and functions.

CONCLUSIONS

Users found digital interventions for eating disorders practical and effective but stressed the need for interventions to address the full range of symptoms, severity, and individual needs. Future digital interventions should be cocreated with users and offer more personalization. Further research is needed to determine the appropriate balance of professional and peer support and whether these interventions should serve as the first step in the stepped care model.

Racial/Ethnic Trends in Virtual Mental Health Care Utilization among Undergraduate Students: An Observational Study (Preprint)
Authors: Loren Dorothy McLeod , Reuter Tracy , Bickham Nassim , Booth Robert T
Published: March 2024

BACKGROUND

Undergraduate students are a population particularly in need of mental health support, but demand has far surpassed campus resources. Many students with a diagnosis do not access any form of mental health care. This gap between mental health diagnoses and access to support is particularly large among Asian, Hispanic, and Black students. Supplementing on-campus care with a virtual-only behavioral health partner may shift these trends by addressing some of the common barriers to receiving mental health care among these groups.

OBJECTIVE

This study aimed to compare the number of undergraduate students engaging in virtual mental health visits as part of a partnership with a company providing virtual-only care, with the total enrolled undergraduate students at the same 113 institutions. We aimed specifically to compare the number of patients engaging in visits among different racial/ethnic groups (White, Asian, Islander, Hispanic, Black, Native, and Multiracial) with total enrollment of the students identifying in that group at the universities.

METHODS

We used de-identified visit data and self-reported race/ethnicity to define the “patient” population of undergraduates accessing care. We compared that to the full “student” population of undergraduates among the same schools, defined by enrollment numbers and admissions-reported race/ethnicity publicly available as part of the Integrated Postsecondary Education Data System (IPEDS). We utilized a chi-square goodness of fit test to compare patient population race/ethnicity with student population race/ethnicity.

RESULTS

Patient population race/ethnicity (N=14,870) differed significantly from student population race/ethnicity (N=619,459). A significant effect (Chi-Square = 2258, P < .001) indicated that patient population demographics were not aligned with student population demographics. Exploratory analyses revealed a complex pattern of results: We found more Asian, Black, and Multiracial patients than expected based on enrollment, in contrast to prior findings indicating these groups are less likely to access traditional mental health care models. At the same time, we found fewer Hispanic patients than expected, aligning with prior results. We also found fewer White patients than expected, in contrast to prior results. There was not a significant difference in the proportion of patients and students who identified as Native or Islander.

CONCLUSIONS

We conclude that, in contrast to prior literature on traditional mental health care settings, some racial/ethnic minority undergraduates (Asian, Black, and Multiracial) may actually access care at a disproportionately high rate under a fully virtual support model. On the other hand, White and Hispanic students may access care less frequently.
Workplace PUA in China before and after the epidemic: Dynamic Topic Model Analysis Based on Microblogging (Preprint)
Authors: Yang Shuhui , Yang Yujie , Wang Yike
Published: March 2024

BACKGROUND

"Workplace PUA" has become a hot topic of discussion on Weibo, and more and more people are beginning to pay attention to "workplace PUA" and the negative impact it brings. At the same time, 2022 is the year of the outbreak of the epidemic. The working mode of online office has also been retained during the epidemic period, workers may be forced to "work overtime online" even after working hours, which may lead to more workplace PUA.

OBJECTIVE

The purpose of this study is to conduct a dynamic study on the behaviour of workplace PUA, to understand the dynamic process of influencing workplace PUA, and to analyse the various potential problems and causes of workplace PUA. It is hoped that it will provide psychological advice to working professionals who are experiencing workplace PUA and help them better plan their future career path.

METHODS

A web crawler was used to crawl the discussion topics about "workplace PUA" on microblogs, and a dynamic topic model was used to study them. 5109 original microblogs were collected during the search period from 2022.11.11 to 2023.4.10.

RESULTS

This culminated in three topics on PUA in the workplace:Rejecting workplace PUA,Negative impact of PUA from COVID-19 defence and control staff,Negative emotions brought about by workplace PUA.

CONCLUSIONS

Chinese netizens before and after the epidemic held strong antagonistic attitudes towards workplace PUA, and workplace PUA itself had extremely negative effects on individuals' physical and mental development, while at the same time it was characteristic of the times during the epidemic. This study helps us to better understand the social phenomenon of workplace PUA, provide professional intervention suggestions for employees who are subjected to workplace PUA, and better assist modern people in making career decisions. In addition, this study creatively applies DTM to the study of social phenomena in the workplace, providing a new reference method for research in this field.
Validation of the Story World Absorption Scale through annotation of online book reviews
Authors: Kuijpers Moniek M. , Lusetti Massimo , Lendvai Piroska , Rebora Simone
Published: March 2024

In this paper we present our attempt at validating a self-report instrument developed in the field of empirical literary studies to capture absorption experiences, namely the Story World Absorption Scale (SWAS, Kuijpers, et al. 2014). We used the SWAS as the foundation for a tag set, that targets mentions of absorption in online book reviews. Online book reviews posted on social media platforms are a relatively new form of reader testimonials that can be of use to researchers from different disciplines to investigate reading experience and evaluation, as well as social discourse about reading. This paper discusses the annotation tag set, which was developed through an iterative process, presented alongside a series of inter-annotator agreement studies that show the validity of our annotation process. Finally, it will discuss the validation and reconceptualization of the Story World Absorption construct, where we consider instances of systematic disagreement during annotation and discuss new categories that we added to the tag set that indicate areas where absorption theory may need to be refined.

Raw water must meet specific physical, chemical, and biological requirements to be suitable for drinking. There are various techniques available for treating wastewater, and aside from conventional methods that involve chemicals, electrocoagulation is an efficient and advanced approach. Electrocoagulation has proven effective in treating many pollutants, including bacteria, viruses, iron, fluoride, sulfate, boron, hardness, and turbidity. Total suspended solids, organic and inorganic materials, chemical oxygen demand COD, biochemical oxygen demand BOD, and color. It finds extensive application in treating different types of water and wastewater due to its exceptional ability to remove diverse contaminants. Recently, electrocoagulation has garnered significant attention due to its remarkable efficiency in treating various pollutants. This article provides a thorough analysis of contemporary literature that is committed to using electrocoagulation in a variety of water treatment methods, with a focus on the different variables affecting the process performance, such as electrical current, electrode type, electrode configuration, initial pH, electrode distance, NaCl concentration, initial concentration of pollutants, operating temperature and electrolysis time.
Motivation, Self-efficacy, and International Students’ Academic Performance
Authors: DING ZIHE
Published: March 2024

This project explored how international students’ learning motivations and self-efficacy can affect their academic performance when studying abroad via a systematic literature review approach. It specifically explored two sets of relationships by outlining the key concepts and theories that predict such relationships, discussing the specialities of these concepts and theories with regard to the research target, international students, and summarising and comparing the findings of empirical studies in specific contexts.The project specifically reveals that international students’ motivations can be enhanced by their clear goals to study abroad and undermined by their sociocultural adaptation to the learning environments. Their self-efficacy beliefs can also be damaged by their language difficulties and adaptation problems. Despite some inconsistencies in empirical research findings, international students’ intrinsic motivations and self-efficacy beliefs can both positively enhance their academic performances. Based on these findings, teachers are suggested to offer adequate social support for international students by providing student counselling services, promoting an inclusive culture, and supporting the construction of international student communities. These methods will assist international students’ cultural and academic adaptation and enhance their academic motivations and self-efficacy beliefs. The teachers are also suggested to differentiate teaching approaches in response to the specific needs of international students and facilitate students’ self-efficacy development through affirmative recognition.
Migración haitiana y racismo: ¿limitaciones del multiculturalismo?

Published: March 2024

¿Qué contradicciones se observan entre el ideario del multiculturalismo relacionado con el derecho a la libre circulación de las personas entre las fronteras de las naciones y las restricciones a la movilidad de ciertos grupos durante el neoliberalismo? ¿Cómo se manifiestan estas contradicciones en el caso de las personas migrantes afrodescendientes haitianas? A través del concepto de interseccionalidad, se ilustra cómo la construcción de la otredad negativa de esta población se origina en su propio país para posteriormente trasladarse a las rutas migratorias. Se analiza este desenlace a partir de un elemento central, el racismo, derivado de la colonización francesa, al que se suman factores históricos, políticos, demográficos y económicos, la vulnerabilidad ecológica y la implementación de estrategias neoliberales a finales del siglo XX, que tornan inviable la sobrevivencia de la población y la obligan a migrar.
Gerencia social, aceleración y lógicas de capital durante la pandemia del COVID-19: experiencias en el contexto colombiano

Published: March 2024

Este trabajo analiza el papel de la gerencia social en un contexto de volatilidad, incertidumbre, complejidad y ambigüedad, propio de la época actual, pero a su vez, subsidiario del modelo económico imperante, y los efectos derivados por la pandemia del covid-19 a escala nacional. Parte de una propuesta conceptual integrativa sobre la administración social, se avanza en la revisión de los fundamentos de esta, a fin de valorar su capacidad de respuesta frente a los desafíos socioinstitucionales que la pandemia planteó al ejercicio de los gestores sociales dentro de dicho período. Para lograr el propósito, se procedió con una revisión de la literatura, a través de bases de datos de tipo académico y repositorios institucionales de organismos multilaterales, donde la gerencia social, aceleración social y lógicas de capital constituyeron el corpus teórico de la reflexión. Los hallazgos más importantes dan cuenta de la necesidad de considerar a la gestión social, más allá de un modelo de administración vinculado con la garantía, acceso y promoción de derechos fundamentales, para resaltar su noción como campo de saber multidisciplinar cuyas actualizaciones, además de considerar lo epistemológico, dan valor al contexto, vía adaptación y ajuste de este mecanismo institucional.

Objetivo: Proponer un modelo de analítica de datos para contribuir al seguimiento del flujo de caja que apoye el sostenimiento de las mipymes. Diseño/metodología: Se llevó a cabo una caracterización de los procesos de flujo de caja en las mipymes colombianas mediante la construcción de un estado del arte y del análisis descriptivo de datos obtenidos a partir de una encuesta.  Resultados: Se ha determinado que la adopción del control de flujo de caja en las mipymes colombianas no es tan frecuente como sería recomendable, considerando su baja tasa de supervivencia. Adicionalmente, se observó que la implementación de este control raramente se realiza utilizando software especializado. En cuanto a los modelos de análisis predictivo examinados, el modelo de bosques aleatorios demostró ser el más eficaz, con una precisión del 76.67, una sensibilidad del 83.33 y una especificidad del 70. En relación con los modelos de análisis descriptivo y diagnóstico, se han desarrollado propuestas de análisis que se adaptan a la naturaleza y disponibilidad de la información a reunir de las mipymes colombianas. Conclusiones: El uso de herramientas informáticas del tipo de analítica de datos puede contribuir a la mitigación de riesgos de iliquidez y de insolvencia de las empresas, ya que les ofrece a los emprendedores una visualización de información del flujo de caja en diversos escenarios, una proyección de posibles periodos de déficit o superávit y un apoyo para una mejor toma de decisiones de operación, inversión y financiación. Originalidad: En estados del arte, realizados entre 2012 y 2022, no se encontraron resultados significativos relacionados específicamente al área de analítica predictiva aplicada al flujo de caja, y ninguno similar al modelo de analítica sobre flujo de caja propuesto en este manuscrito, el cual busca reducir la cantidad de mipymes que quiebran Colombia debido al desconocimiento de su información financiera y la falta de apoyo en la toma de decisiones.
