Published: January 2024

This research study discusses key issues concerning the Network Security (NS) of the healthcare and medical facilities. Particularly, it aims to shed light on the emerging cybersecurity threats and risks encountered by these facilities and the proposed countermeasures that can prevent, detect and respond to security threats (e.g., cyberattacks), vulnerabilities, and risks (e.g., financial or operational risks), and can serve to mitigate any damages and/or disruption caused by the exposure to any of the aforesaid incidents. In the current qualitative study, the researcher adopted the Analytical Approach as the research method that was utilized for the sake of gathering, analysing, interpreting the available literature of the subject -under investigation-, and eventually making inferences and reaching conclusions. Based on carrying out the previously-mentioned Analytical Literature Review, several findings were revealed by this study. Precisely, the study demonstrated that due to the Digital Transformation and the Digitization adopted by the healthcare sector, the vulnerability and fragility of the healthcare and medical facilities security networks and information/operational systems have been increased. Such deficit in the cybersecurity level had eventually led to the exposure of these facilities to several types of cyberattacks, network penetration, and many other cybercrimes. The findings of the study also demonstrated that the cyber threats can take the forms of: Malware, Ransomware, Phishing, and Insider Threats. Similarly, the cyberattacks types include Network Attacks, Wireless Attacks, Malware Attacks, and Social Engineering Attacks. Finally, the study revealed several cyberattacks countermeasures, include: 1) Raising the awareness of the healthcare and medical facilities workforce 2) Keeping the organizations software and systems fully up to date 3) Implementing Endpoint Protection Software 4) Installing a Firewall 5) Backup the organizations data 6) Securing the organizations Wi-Fi network and 7) Managing the healthcare and medical facilities employees personal accounts. Further countermeasures include the implementation of Risk Assessment, Authentication, Data Retention.

This paper explores the possibility of predicting the production of a prosumer by artificial neural networks. We made a cross comparison of two ANNs architectures (looped and unlooped) with respect to multivariable regression in order to have an efficient and reliable tool for predicting the production of a photovoltaic installation from meteorological data (solar irradiance and ambient temperature).To accomplish these goals, we used monitoring data of an installation over a period of 72 days to realize, train and test two ANNs topologies (looped and unlooped) which are trained with the Levenberg-Marquardt algorithm. After training and testing, it first appears that the neural networks show the best performance compared to the multivariable regression method. Then, among the two architectures, the one with the lowest uncertainties (ÃƒÂ°Ã‚ÂÃ‚Â‘Ã‚Â€ÃƒÂ°Ã‚ÂÃ‚ÂÃ‚Â´ÃƒÂ°Ã‚ÂÃ‚Â‘Ã‚ÂƒÃƒÂ°Ã‚ÂÃ‚ÂÃ‚Â¸=24.489% ÃƒÂ°Ã‚ÂÃ‚Â‘Ã‚Â…ÃƒÂ°Ã‚ÂÃ‚Â‘Ã‚Â€ÃƒÂ°Ã‚ÂÃ‚Â‘Ã‚Â†ÃƒÂ°Ã‚ÂÃ‚ÂÃ‚Â¸=436.08 and MBE=30.93) is the feed-forward architecture.In this article, we have shown the importance of managing energy supply and demand, but also the main drawbacks of the current electricity network in Senegal.In summary, we have developed a model capable for predicting the production of a prosumer based on meteorological data (sunshine and ambient temperature).

Rheumatoid arthritis is a persistent inflammatory illness that impairs joint function by destroying cartilage and causing synovitis. It is a debilitating illness that affects every joint in the body. Additionally, it manifests extra-articularly, impacting the auditory system as well as ENT manifestation. Regarding Laryngeal Symptoms, dysphonia or changes in voice quality can be caused by autoimmune illnesses in general and RA in particular. These changes can be caused by either functional or anatomical l modifications.Material and Method: 60 adults with rheumatoid arthritis classified into two groups the 1st group have disease duration less than or equal to 5 years and the 2nd group is more than 5 years. Disease activity was assessed using DAS 28 (Disease activity score). The entire patient underwent otoscopic examination of ears & Laryngeal examination as well asfull audiological evaluation including pure tone and speech audiometry and immetencemetryin the form of tympanometry and acoustic reflexes to assess middle function. Results: A total of 60 patients, 40 patients with a disease duration of less than or equal to five years (1st group). The 2nd group had disease duration of more than five years they were 20 patients. In RA patients the disease activity score was done using DAS-28 CRP, the first group with mean 5.3Â±1.3, the second group had a mean 5.9Â± 1.4. As for the Otorhinolaryngological findings we found that otalgia &myringo sclerosis and rhinogrnic findings there are no significant difference between the two groups. As regard laryngeal findings there are no significant difference between the two groups as regard edema, GERD and laryngeal swellings. Hearing loss was present in 16 (40%) patients in the first group and 17(85%) patients in the second group with highly significant difference between the two groups,there was direct correlation between disease duration °ree of hearing loss. Conclusion: our research revealed that the duration of RA had little bearing on laryngeal findings. On the other hand, the length of the illness had an effect on rhinogenic findings. Additionally, duration of RA and hearing test showed a direct association.

Introduction: Ardhavabedhaka is a condition characterized by severe pain in half of the head, such as bheda, toda, bhrama, shula appearing in interval of either 15 or 10 days or spontaneously without any cause1. This disease shows close resemblance to migraine. Migraine is a neural condition characterized by severe recurrent headache usually on one side of the head often accompanied by nausea, vomiting and photophobia2. Migraine affects globally 12% of the population. In India 14.12%-25.2% population and it is a disease predominantly seen in females, with male to female ratio of 1.7:2.6 and among those from urban than rural areas 1.3:1.83. Currently, migraines are managed by usage of analgesics and triptans. Chronic usage of these drugs may cause renal and hepatotoxicity. Therefore, it is necessary to explore ayurvedic approaches that can combat the disease. In Ayurevda this disease is managed by usage of uttama matra of chatuhsneha, shirokaya virechana, nadi sweda, niruha basti, anuvasana basti and shamanaoushadi. As Nasya karma is the prime treatment modality for the management of urdhwa jatrugata vikaras, it is considered appropriate for management of Ardhavabedhaka4. Materials and Methods: The study was conducted using Brihat dashamoola taila as nasya for 8 days and Rasna dashamooladi Kashaya as shamanoushadhi for 23 days post nasya in group 1 and Varunadi ksheera ghrita nasya for 8 days and Munditaka Kashaya as shamanoushadhi for 23 days post nasya in group 2. The assessments were done on the domains of intensity of pain, frequency of attacks and duration of pain, along with the Headache impact score, on the 0th, 8th and 31st days, before and after the treatment. Result: It showed that there was significant decrease in intensity, frequency, duration of pain and Hit score, post nasya karma in both group 1 and 2, also the reduction in pain was significant in both group 1 and 2 post shamanoushadhi. With the overall treatment, it was seen that the reduction in Hit score was highly significant with a p value of 0.000. On comparing the results obtained in both groups, it was observed that group 1 had significant results compared to group 2. Conclusion: Nasya karma works as a treatment of choice in Ardhavabhedaka, due to its ability to eliminate the accumulated doshas from the shiras. The present study showed that Brihat dashamoola taila nasya along with Rasna dashamoola kashaya gives better results in vatakapha pradhana Ardhavabhedaka, and Varunadi ksheera ghrita nasya along with Munditaka Kashaya works better in vatapitta pradhana Ardhavabhedaka.

Authors: F.S Ezeruigbo Chinwe
Published: January 2024

The phase of adolescence holds significant importance as it marks a critical period for initiating habits that can have enduring effects. This is crucial in preventing avoidable illnesses and fatalities resulting from unfavorable health-related actions, like the use of substances. This current research was conducted to assess the understanding, perspectives, and actions of secondary school educators regarding the prevention of substance use among adolescents. This initiative seeks to identify factors that might impede the efficacy of substance use prevention programs within secondary educational institutions. Descriptive research design was carried out in three select secondary schools: Uwani Secondary School, Maryland Secondary School, and Federal Government College Enugu, in Enugu state. Ninety-two (92) participants were sampled using a multi-stage sampling technique. The self-administering questionnaire was used as a tool for data gathering. The filled questionnaires that met the criteria for analysis were coded into the computer using SPSS software and data were analyzed using descriptive statistics and presented in frequency and percentage. Knowledge of the attributes that increase the risk of adolescent substance use is poor at 88% of the respondents, while attitude and practice were fair. The knowledge of attitudes and practices of secondary school teachers in Enugu state on the preventive measures for substance use among adolescents is inadequate. Therefore, for effective intervention on substance use preventive strategies in adolescents, teachers and other workers in secondary schools should be equipped with adequate knowledge concerning substance use preventive practice.

Published: January 2024

Drug and Therapeutics Committees (DTCs) have been identified and promoted as a fundamental model in advancing the rational management and use of essential medicines and health supplies in hospitals since the 1970s. However, there is still a scarcity of comprehensive literature on their current structure and actual roles performed in various countries. We conducted a scoping review using the Pubmed and ResearchGate databases and included eligible articles published between 2010 and 2023, to assess the structure and roles performed by hospital DTCs. The database search yielded 47 potential records, but only seven of these were eligible for inclusion. Studies included were from both high-income and low- and middle-income countries. The structure of DTCs is generally similar across these countries, with minor contextual variations. All DTCs are heterogeneous in composition and contain both medical and non-medical staff. The DTC leadership comprises a chairperson who is usually a senior clinician, and a secretary who is usually a pharmacist. The majority of the DTCs have at least one sub-committee, and antimicrobial stewardship is the most common. The DTCs still perform their customary roles, although their role scope is expanding. In some countries, the DTCs have taken on additional roles due to the evolving medicines management and use problems, and technologies. There is however still a dearth of recent primary data on the structure and roles of DTCs in many countries. We recommend more primary research to understand the status of DTCs in various countries and to provide more insights into the existence and functionality of the DTC sub-committees.

This study in Kaduna State, Nigeria, examined the prevalence, and factors as associated with COVID-19 infection and mortality among frontline healthcare workers (HCWs) in a descriptive, cross- sectional study, where data of HCWs from secondary source, Surveillance Outbreak Response Management and Analysis System (SORMAS), was exported to Microsoft excel and evaluated using SPSS version 26 to provide a snapshot of the vaccine uptake among HCWs in Kaduna state. The study population were all healthcare workers in Kaduna State, Nigeria that were tested for COVID-19 from the onset of the pandemic in Kaduna to 29th August 2022. The consents of all persons were obtained prior to testing data upload to the electronic platform of SORMAS. Prevalence of COVID-19 infection was notably higher pre-vaccination (12%) but dropped to 5.9% post-vaccination, showcasing the vaccine’s effectiveness in reducing HCW infections. However, COVID-19-related mortality rates remained relatively consistent, irrespective of vaccination status. Demographics played a role in infection risk. Female HCWs, urban dwellers, and those with higher education levels faced elevated infection risks. Additionally, close contacts with probable COVID-19 cases increased infection likelihood. Concerning mortality, males experienced more COVID-19-related deaths, but no significant links were found with age, residential area, or contact history. Symptoms significantly associated with COVID-19 infection included fever, abdominal pain, cough, sore throat, loss of taste, and loss of smell. The prevalence of COVID-19 infection among the HCWs was higher before the COVID-19 vaccination was introduced (12%) compared to after the vaccine was introduced in Kaduna State. These findings offer valuable insights into the pandemic’s impact on frontline workers in Nigeria’s Kaduna State.

Authors: Chipalo Edson
Published: January 2024

Sexually transmitted infections (STIs) are a public health crisis that can be devastating to individuals with adverse childhood experiences (ACEs). This study examined the prevalence and association between ACEs and self-reported STIs among adolescents and young adults in Zimbabwe. Data for this study was derived from the 2017 Zimbabwe Violence Against Children Survey (ZVACS) from the participants aged 13 to 24 (n=504). The self-reported prevalence estimates of STIs were calculated using weighted frequencies and percentages. Two logistic regression models were employed to assess an association between eight ACE types and self-reported STIs. The findings revealed that STIs were higher among orphans (52.2%), followed by participants with a history of lifetime suicide ideation or attempts (49.8%), were exposed to any ACE (42.5%), and had moderate/severe mental distress in the past 30 days (44.8%). Additionally, self-reported STI rates were higher for participants who experienced any form of physical violence (30.8%), witnessed physical violence (22.4%), experienced sexual violence (16.1%) and emotional violence (11.7%). In unadjusted regression models, all ACEs, except participants who experienced emotional violence, were significantly associated with self-reported STIs. However, after adjusting for covariates in the model, none of the ACEs maintained a significant association with self-reported STIs. Despite this, it is evident that interventions remain crucial for effectively preventing STIs for individuals with ACEs. There is a pressing need to implement and expand STI prevention programs nationally, including identifying and addressing ACEs and early screening, diagnosis, and treatment of STIs among adolescents and young adults in Zimbabwe. Keywords: Adverse childhood experiences (ACEs), Adolescents, sexually transmitted infections (STIs), Violence, Young adults, Zimbabwe.

Authors: Chipalo Edson
Published: January 2024

Refugees who have resettled in the United States encounter numerous challenges, including poor health conditions. However, knowledge of risk factors contributing to chronic debilitating conditions among refugees is scarce. Therefore, this study examined the prevalence and potential factors associated with chronic debilitating conditions within the U.S. refugee population. This study utilized secondary data from the 2019 Annual Survey of Refugees (ASR) involving 1007 refugees aged 16 years or older resettled in the U.S. between 2014 and 2018. The prevalence estimates were obtained using chi-square tests, and multiple logistic regression was used to determine the significant association between predictor variables and chronic debilitating conditions for refugees in the United States. About 25.5% of the refugees reported having chronic debilitating conditions. Regression results showed that being an older refugee and having adjusted immigration status to become a permanent resident was associated with higher odds of reporting chronic debilitating conditions. However, refugees who were currently working, married, and with good English language proficiency were associated with a lower likelihood of reporting chronic debilitating conditions. Gender and education levels of refugees were not significantly associated with chronic debilitating conditions after covariates adjustments. Interventions should focus on increasing access to education, employment opportunities to enhance health literacy, and financial resources to access healthcare crucial for mitigating chronic debilitating conditions. In addition, addressing the language barriers through language and interpretation services in clinical settings can also improve healthcare access, thus reducing the risk of chronic debilitating conditions among refugees resettled in the United States. Keywords: Chronic debilitating conditions, English proficiency, Immigration, Refugees, United States.

Classified as self and non-self-referrals, the ideal situation is that patients begin from lower levels of healthcare to higher levels. This improves the utilization of the primary care units, reduces unnecessary congestion of higher levels and makes for efficient healthcare delivery in general. This study aimed to assess the prevalence and predictors of self-referral among patients accessing healthcare in a tertiary hospital in Calabar, Nigeria. Ethical approval and informed consent were obtained. The study adopted quantitative data collection methods. This facility-based, cross-sectional study was carried out among 400 patients aged 18 years and above accessing care in the General Outpatient Clinic of the University of Calabar Teaching Hospital, Calabar in Cross River State. Overall, 191(47.8%) were males while 209(52.3%) were females. The mean age of study participants was 40.5±13.4 years, the most common age group was 31 to 40 years (28.2%). Prevalence of self-referral was 68.3%. Factors significantly associated with self-referral practices were sex (p<0.001), age group (p<0.001), marital status (p<0.001) and occupation (p=0.006). At multivariate regression analysis, females compared with males (OR: 5.299; 95% CI: 3.271 to 8.587), as well as those who were presently unmarried compared with those presently married (OR: 1.920; 95% CI: 1.052 to 3.505) were significantly more likely to practice self-referral. Self-referral practice is common and sex and marital status were identified as predictors. This is more so with unmarried females. Interventions to promote utilization and referral by healthcare providers through the prescribed channel is strongly recommended.

O efeito dos ajustes de exercícios anteriores no patrimônio líquido e no ROE de companhias listadas no Novo Mercado da B3
Authors: Silva Fernanda de Deus Vieira , Silva Denise Mendes da , Santos Geovane Camilo dos
Published: January 2024

Objetivo: Analisar o efeito dos ajustes de exercícios anteriores (AEA) no Patrimônio Líquido (PL) e no Retorno sobre o Patrimônio Líquido (ROE).
Metodologia: Foram pesquisadas as Demonstrações das Mutações do Patrimônio Líquido (DMPL) e as Notas Explicativas das companhias listadas no Novo Mercado da B3, de 2010 a 2019. Para analisar os efeitos dos AEA no PL e no ROE, aplicou-se o teste de Wilcoxon.
Resultados: A maior parte dos AEA identificados referem-se a mudanças de política contábil, notadamente relacionadas à aplicação da IFRS 9/CPC 48 e IFRS 15/CPC 47, em 2018. Isso significa que as companhias escolheram reconhecer os efeitos da adoção dessas normas de forma retrospectiva, com efeito cumulativo no PL, sem a apresentação das informações comparativas (escolha contábil). Houve diferença estatisticamente significativa entre as variações médias do PL e do ROE ajustados e não ajustados (com e sem AEA). Em outras palavras, observa-se que há influência de mudanças de políticas contábeis e/ou retificações de erros na análise desses indicadores. Importante ressaltar que os AEA não devem afetar o resultado líquido do exercício corrente, sugerindo que os efeitos decorrentes de mudanças de políticas contábeis e erros tendem a proteger resultados presentes e/ou futuros em detrimento de resultados passados.
Contribuições do Estudo: A principal contribuição do estudo reside em avaliar alterações no PL que não decorrem, necessariamente, do desempenho operacional ou das estratégias de financiamento, mas advindas das mudanças de critérios contábeis ou erros, que podem afetar outros componentes patrimoniais.

Authors: Souza Wellington Rodrigues Silva
Published: January 2024

Objetivo: O objetivo do artigo é analisar os efeitos da adoção do CPC 06 (R2) – Arrendamentos na rubrica de aluguéis da Demonstração do Valor Adicionado (DVA) e no percentual de distribuição do valor adicionado como aluguéis.
Metodologia: O estudo é quantitativo quanto à abordagem e documental quanto ao método de coleta de dados. A amostra é composta por empresas comerciais listadas na B3. Efetuaram-se análises de variações e teste de postos com sinais de Wilcoxon sobre a rubrica de aluguéis da DVA e sobre o percentual de distribuição do valor adicionado como aluguéis destas empresas nos triênios posterior (2019-2021) e anterior (2016-2018) à adoção do CPC 06 (R2).
Resultados: Identificou-se que, após a adoção do CPC 06 (R2), houve uma expressiva redução nos valores da rubrica de aluguéis da DVA e no percentual de distribuição do valor adicionado como aluguéis das empresas componentes da amostra. Isso ocorreu porque as empresas vêm alocando os pagamentos de uma mesma natureza econômica (remuneração a terceiros por usufruto de seu capital) em três diferentes rubricas na DVA, quais sejam, aluguéis, depreciação e juros. O teste de postos com sinais de Wilcoxon indicou diferenças estatisticamente significativas no valor médio da rubrica de aluguéis da DVA e no percentual médio de distribuição do valor adicionado como aluguéis no triênio posterior à implementação do CPC 06 (R2) em comparação com o triênio anterior.
Contribuições do Estudo: O artigo contribui com a literatura a respeito dos arrendamentos e da DVA, sendo pioneiro na análise dos efeitos dos arrendamentos sobre esta demonstração após a adoção do CPC 06 (R2). Também contribui com usuários das informações contábeis para que compreendam os efeitos dos arrendamentos sobre a DVA e interpretem adequadamente as rubricas afetadas em decorrência do CPC 06 (R2). Por fim, contribui com reguladores, pois sinaliza um potencial necessidade de revisão da norma sobre DVA.

Published: January 2024

Objetivo: Este artigo busca elucidar se a particularidade do alto nível de explicação da relação do retorno da carteira de mercado e o retorno das ações de empresas do setor de petróleo no Brasil ocorre de maneira semelhante em outros mercados.
Metodologia: A pesquisa considerou as principais petrolíferas elencadas pelas revistas Forbes, Fortune e Exame a partir de seu valor de mercado e de receita em dólar no ano de 2018, assim como a movimentação de suas ações e das respectivas carteiras de mercado no período de 02 de janeiro de 2015 e 31 de março de 2021. Inicialmente foi efetuada uma regressão simples considerando um fator sistêmico, através da métrica do CAPM. Posteriormente, foram acrescidos outros fatores (taxa do dólar e preço do barril de petróleo tipo Brent e WTI) com vistas a eventual melhoria do modelo, utilizando-se a métrica multifatorial – APT. Como forma de identificar os impactos da Covid-19, os períodos foram segregados em integral, ex-ante e ex-post. Neste formato, o período ex-post apresentou resultados “não esperados”, o que levou a pesquisa a segregá-lo em trimestres.
Resultados: Os resultados obtidos em todos as análises confirmaram, embora parcialmente, que o alto poder de explicação (superior a 50%) da variabilidade do retorno das ações ordinárias da Petrobras pela variabilidade do retorno da carteira de mercado do Ibovespa (B3), ocorre em outros mercados. A pesquisa observou que o Coeficiente de Explicação tende a captar de forma mais significativa os efeitos de crises que advêm de contextos econômicos locais e impactos para a economia mundial, a exemplo de eventual redução no nível do produto interno bruto de países como os Estados Unidos ou a China. Já para evento inesperado, a exemplo da Covid-19, o modelo, em princípio, não apresentou igual resultado, o que pôde ser observado nas análises trimestrais.
Contribuições do Estudo: A pesquisa contribui nas tarefas de gestores e investidores, ao demonstrar as similaridades que preveem eventos futuros relacionados à cotação do mercado acionário e que, por consequência, auxiliam em tomadas de decisões dos stakeholders.

Authors: Gonçalves Cinthia Moysés , Bressan Valéria Gama Fully , Souza Gustavo Henrique Dias
Published: January 2024

Objetivo: Identificar os fatores determinantes da Livre Admissão de associados em cooperativas de crédito brasileiras entre 2016 e 2020.
Metodologia: Utilizou-se um modelo de regressão logística para estimar tais fatores. A análise considerou tanto variáveis internas específicas das cooperativas (idade, tamanho do ativo, número de cooperados e filiação a sistemas) quanto variáveis que representam o ambiente macroeconômico no qual essas instituições estão inseridas (índice de desenvolvimento municipal, número de habitantes nos municípios que possuem postos de atendimento (PACs) e sede das cooperativas).
Resultados: Os principais resultados apontam que quanto menor o número de habitantes dos municípios sede e que contém PACs, maior a probabilidade de ocorrência de Livre Admissão. Além disso, cooperativas com maior número de cooperados e ativos também têm maior probabilidade de adotar a Livre Admissão.
Contribuições do Estudo: O estudo destaca a predominância de cooperativas com Livre Admissão em municípios menores e menos desenvolvidos, reforçando o papel dessas cooperativas na inclusão social, redução de desigualdades e oferta de serviços financeiros e de crédito para a população dessas localidades. Além disso, os resultados fornecem subsídios valiosos para formuladores de políticas, instituições financeiras e cooperativas interessadas em promover o desenvolvimento socioeconômico e a equidade em comunidades menos atendidas pelo sistema financeiro.
Analysis of the relationship between the profitability of market portfolios and the profitability of shares of companies in the oil sector
Authors: Silva Marcos Donizeti da , Santos José Odálio dos , Santos Fernando de Almeida , Carvajal Júnior Cláudio José
Published: January 2024

Purpose: This article aims to elucidate whether the particularity of the high level of explanation of the relationship between the return on the market and the return on shares of companies in the oil sector in Brazil occurs similarly in other markets.

Methodology: The oil companies considered were listed as the main ones by Forbes, Fortune and Exame magazines. Their shares and market movement were obtained from their respective host countries stock exchanges, and other information on institutional websites (e.g: OPEC - Organization of the Petroleum Exporting Countries). As theoretical support, CAPM and APT metrics were applied between from January 2, 2015, to March 31, 2021.

Results: Considering the privileged position of the fuel sector for the movement of the level of economic activity of the countries, the result of this research confirmed that the particularity of the Brazilian scenario is observed in other countries with regard to the high level of explanation of the return of the superior market portfolio at 50%. The research observed that the Explanation Coefficient tends to capture in a more significant way the effects of crises that come from local economic contexts and impacts on the world economy, such as a possible reduction in the level of gross domestic product of countries such as the United States or China. As for the unexpected event, such as Covid-19, the model, in principle, did not present the same result, which could be observed in the quarterly analyses.

Contributions of the Study: Research can help managers and investors, as by demonstrating similarities one can predict future events or assist in decision-making.
Determinants of open membership in brazilian credit unions
Authors: Gonçalves Cinthia Moysés , Bressan Valéria Gama Fully , Souza Gustavo Henrique Dias
Published: January 2024

Purpose: To identify the determining factors of Open Membership in Brazilian credit unions between 2016 and 2020.

Methodology: A logistic regression model was used to estimate these factors. The analysis considered both specific internal variables of the cooperatives (age, asset size, number of members, and affiliation to systems) and variables representing the macroeconomic environment in which these institutions operate (municipal development index, population size in municipalities with service points (PACs) and cooperative headquarters).

Results: The main results indicate that a lower population size in the municipalities containing the cooperative headquarters and PACs increases the probability of Open Membership. Additionally, cooperatives with a larger number of members and assets also have a higher likelihood of adopting Open Membership.

Contributions of the Study: The study highlights the predominance of cooperatives with Open Membership in smaller and less developed municipalities, reinforcing the role of these cooperatives in social inclusion, reduction of inequalities, and provision of financial services and credit to the population in these locations. Moreover, the results provide valuable insights for policymakers, financial institutions, and cooperatives interested in promoting socio-economic development and equity in underserved communities by the financial system.
Remains payable from brazilian federal universities: an analysis in the period 2015-2022 from the perspective of Punctuated Equilibrium Theory
Authors: Santana Simonne Saraiva Nunes , Silva Ana Camila da , Nascimento João Carlos Hipólito Bernardes do
Published: January 2024

Purpose: To analyze from the point of view of the Punctuated Equilibrium Theory, the unprocessed Remains payable stock, in order to identify the periods of equilibrium and variations within the scope of Brazilian Federal Public Universities.

Methodology: The research is classified as to the focus as descriptive. To achieve the proposed objective, the data collection was carried out through documentary research, regarding the approach, the research is quantitative, a sample of 69 IFES was adopted. The variables used in this study were: Unprocessed Remains Payable registered, re-registered and canceled. The temporal aspect of analysis of the variables was the years 2015 to 2022.

Results: This study verified the adherence of PET in the evolution of the Unprocessed Remains Payable stock and identified periods of unusual variations in the universities' RAP. After this analysis, the presence of an equilibrium pattern with interruptions was evident, which confirms the central hypothesis that the Theory of Punctuated Equilibrium is relevant to analyze budget fluctuations in the Brazilian context.

Contributions of the Study: As a theoretical contribution, the research fills a gap by analyzing the behavior of RPNP in times of instability. In a practical context, this study helps public managers in the management of outstanding payments and in the balance of public accounts. Finally, the social contribution resides in improving the mechanisms for managing public accounts, which can be translated into improved public spending.
Analysis of the perception of auditors from a federal public network HEI concerning the institutionalization of internal control practices
Authors: Araújo Davi Jônatas Cunha , Araújo Sheila Alice Gajadhar
Published: January 2024

Purpose: To analyse the perception of auditors from a federal public network HEI on the institutionalization of internal control practices.

Methodology: The questionnaire was administered to internal auditors from a federal public network HEI, and the content of their answers was analysed using Iramuteq® software. The software resources used were factor analysis, similarity analysis and word clouds. These resources served to capture the intended meanings in the set of answers of the three research participants and how their words are associated with the institutionalization of control practices.

Results: The auditors presented a more critical perception of the institutionalization process in the sedimentation phase of internal control practices, although they reported aspects that confirm actions corresponding to all phases of this process in the focal HEI.

Contributions of the Study: This study confirms that internal auditors from a public HEI in the federal network better perceive the practices of internal control when they are in the sedimentation phase, which influences their evaluation of these university practices.
