Implementation and Evaluation of an Anti-Fraud Prototype Based on Generative Artificial Intelligence for the Ecuadorian Financial Sector
Authors: Peña Isaac Patricio Arteaga , Ortega-Castro Juan Carlos
Published: August 2024

Objectives: This study aims to develop a more economical and simpler alternative to the current anti-fraud systems in the popular and solidarity financial sector in Ecuador. Given the growing threat of banking fraud in Latin America and the regulatory requirements of the Superintendence of Popular and Solidarity Economy of Ecuador, a solution based on generative artificial intelligence (AI) is proposed to identify fraudulent transactions on mobile and web banking platforms.
 
Theoretical Framework: The implementation of anti-fraud systems in the financial sector is a complex challenge due to the evolving nature of fraud and the limitations of current systems, such as Custodian360, Monitor Plus, and Sentinel, which are perceived by more than 50% of surveyed professionals as costly and complex to implement. In this context, artificial intelligence, and specifically generative language models like GPT, present an opportunity to develop more accessible and effective solutions.
 
Method: A prototype was developed using the LLaMA3 GPT engine (8B parameters) and the Ollama framework, in addition to OpenAI models like ChatGPT 3.5 and 4. The methodology included a proof of concept in which a prompt was parameterized in Ollama, specifying fields of transactional frames in JSON format and defining anti-fraud rules in natural language. These rules were shared by Dycotein, enabling the identification of potentially fraudulent transactions.
 
 Results and Discussion: The results indicated that models with fewer parameters, such as LLaMA3 8B and ChatGPT 3.5, are not suitable for the effective implementation of anti-fraud systems due to their limited capacity to handle complex rules. However, ChatGPT 4 showed promising results with simple rules, suggesting that while they are not a complete replacement for traditional programmatic systems, generative AI models can complement existing solutions, especially in less complex scenarios.
 
Research Implications: The findings of this study highlight the need for continued research and development of more advanced generative AI models for fraud detection, as current technologies are not yet fully effective for complex scenarios. Additionally, the importance of balancing cost and effectiveness in the implementation of anti-fraud systems is emphasized, especially in sectors with limited resources such as the popular and solidarity financial sector.
 
Originality/Value: This article presents an innovative approach to the use of generative artificial intelligence for the development of anti-fraud systems in a financial sector with budgetary constraints. By exploring the potential of advanced models like ChatGPT 4, the research opens new avenues for the creation of more accessible and adaptable solutions, offering significant value to the industry and academia in a context of increasing financial fraud in Latin America.
Changes in Topographic Parameters for the Demarcation of Hilltop APP: an Analysis of the Landscape in the Municipality of Nova Friburgo
Authors: Carvalho Junior Carlos Eduardo Falcão de , Carvalho Ana Cristina Malheiros Gonçalves , Nunes Rafael da Silva
Published: August 2024

Objective: To compare the current Forest Code, Law No. 12,651 of May 25, 2012 (BRAZIL, 2012), with the former Forest Code, Law No. 4,771 of September 15, 1965 (BRAZIL, 1965), to evaluate the impacts on the extent and occupation of protected areas resulting from the new parameters using the Municipality of Nova Friburgo/RJ as the study area.
 
Theoretical Framework: Developments and concepts of the Forest Code by Rajão et al. (2021), Azevedo (2013, 2019), Ramos (2018), and Machado and Torres (2013). Modeling in the ArcGIS environment with MapBiomas and CPRM databases.
 
Method: The research is based on geoprocessing technologies and remote sensing to delineate hilltops according to both Forest Codes. This procedure is based on the modeling by Silva, et al. (2017), suitable for ArcGIS. Three scenarios are comparatively analyzed to identify the distribution of land use and cover in protected regions, 10 years before and after the decree of the current Forest Code.
 
Results and Discussion: Comparative analysis shows that changes in topographic parameters reduce hilltop APP by 87.72% in the municipality of Nova Friburgo. There is an observed increase of 2.69 hectares of urbanized area and 175.88 hectares of forestry in these unprotected areas.
 
Research Implications: Analysis of hilltop APPs indicates that the current Forest Code is flexible and does not ensure the preservation of areas aggregated to the former code.
 
Originality/Value: To assist managers in reviewing the Forest Code. The comparative analysis between the Forest Codes allows for the comparison to identify the potential of changing topographic parameters.

Based on the materials of the Far East, specific analytical tasks were solved: the real process of development of local self-government as the basis of grassroots democracy in Russia was revealed, the personnel policy in relation to municipalities was analyzed. The internal problems of the functioning of the Soviets in the region in 1991–1993, before their departure from the historical arena, were established. The conclusion is substantiated that one of the problems of the Far East in the 1990s was the deepening detachment of the majority of citizens from real self-government. It is shown that behind the facade of reforming the system of self-government bodies in Russia, there was often a task of practical solution of the political tasks of the Center in relation to the regions.

Authors: Syed Tariq , Alminhali Ammar , Bawarith Faris
Published: August 2024

Temperature regulation is crucial for treating and preventing brain damage and the death or disability that follows in people who have cardiac arrest outside of a hospital. Hence, this review was conducted between 2020 and 2023 to evaluate the impact of therapeutic hypothermia in post-cardiac arrest patients. The literature for pertinent studies was searched using Google Scholar, Web of Science, Cochrane, and PubMed. Various combinations of the terms "therapeutic," "hypothermia," "post," "cardiac," "arrest," and "mortality" were used. Only eight of the 105 articles that were gathered met the criteria for inclusion. The research population consisted of 7,192 individuals who had cardiac arrest. Patients who had out-of-hospital cardiac arrest (OHCA) showed more positive outcomes and full recovery if they were cooled down early. Compared to cooling that was begun at the hospital, intra-arrest cooling, which began less than 20 minutes after the collapse, did not result in better neurological results. When comparing patients with hypothermia with normothermia, it was shown that hypothermia patients had superior results as compared to normothermic patients. Nevertheless, after 6 months, there was no difference in mortality when the body temperature was lowered to 33°C after an OHCA as opposed to keeping it at a normal level. Following an OHCA, there was often only little cognitive impairment.

The effect of religiosity and tacit self-declare halal cues on skepticism and patronage intention of self-declare halal restaurant
Authors: Sugiarto Catur , Afrizal Reza
Published: August 2024

The food industry is significantly prominent for exhibiting consumer segmentation in countries developing their halal industry. Due to the absence of appropriate certification, not all businesses within the industry employ authentic labels, leading to self-declare claims as a means of assuring consumers of the halal status of their products or services. Therefore, this study aimed to contribute to the advancement of marketing communication literature, by specifically enhance skepticism the impact of religiosity (REL), as well as implicit self-declare halal cues on (SKEP) and patronage intention (PIE) among relevant restaurant consumers. To obtain significant information, an online questionnaire was implemented and distributed to 297 participants. The results showed that both REL and tacit self-declare halal cues (TSHC) negatively affected SKEP towards relevant restaurants. From this context, more TSHC shown in the restaurant and the higher level of REL led to less SKEP of consumers. Mediation analyses were also implemented to evaluate the indirect relationship between these variables. This emphasized the construction of a mediation model to provide subsequent insights into the mediating role of SKEP and its attitude towards halal restaurants (ATHR). Based on the results, SKEP played a mediating role in the relationships between REL-PIE and TSHC-PIE.

Published: August 2024

There has been a limited amount of research conducted on the specific outcomes associated with harmonious and obsessive passion. Therefore, this study aims to fill the gap by examining the effects of harmonious and obsessive passions on entrepreneurial self-efficacy and curiosity. Distinctions between the impacts of harmonious and obsessive passions are established, setting it apart from previous studies. The results show that harmonious passion positively impacts entrepreneurial self-efficacy, whereas obsessive passion lacks such an effect. However, both types of passion positively influence entrepreneurial curiosity. The sample consists of 236 housewives from Banyumas Regency, selected through convenience sampling. Moreover, this study suggests that harmonious passion yields more beneficial outcomes than obsessive passion. Practical applications of the results include fostering entrepreneurial self-efficacy in housewives by enhancing harmonious passion through internalization processes. These processes can be facilitated through entrepreneurial-focused interventions, such as training programs, educational modules, and participation in entrepreneurial events.

Published: August 2024

In this study, we will use the audit committee as a moderator to look at how various disclosures such as general information, mandated disclosure, and corporate social responsibility affect the cost of equity capital. Specifically, this study relies on secondary data mined from sustainability and annual reports. This study's population consists of energy, consumer non-cyclical, and consumer cyclical enterprises that have been listed on the Indonesia Stock Exchange (BEI) between 2019 and 2022. This study uses the technique of purposive sampling to gather data. There is an imbalance in the data set since various companies had varied numbers of observations during the study period. From 2019 through 2022, 133 companies' data sets were deemed suitable for inclusion in the sample. This data study makes use of Eviews, a quantitative data analysis tool, to analyze the data using panel data analysis. Findings suggest that disclosures pertaining to general information and obligatory disclosures reduce the cost of equity capital, however disclosures on information asymmetry and corporate social responsibility do not. Audit committees have limited power to affect equity capital costs by reducing the impact of information asymmetry and increasing CSR disclosure; however, they are unable to do so with forced disclosure or general information disclosure

Authors: Venkatasubramanian Vaishnavi , Sethi Jasmine , Kumar Vivek , Yadav Ashok Kumar , Lal Anupam , Kohli Harbir Singh
Published: August 2024

Background:

Autosomal dominant kidney disease (ADPKD) is the most common monogenic disorder leading to renal failure with limited therapeutic options. We aimed to assess the efficacy and safety of metformin in nondiabetic ADPKD patients and its role in slowing disease progression.

Materials and Methods:

We conducted a prospective, randomized controlled, open labelled clinical trial and enrolled 52 nondiabetic adults aged 18–60 years with typical ADPKD, estimated glomerular filtration rate (eGFR) > 45 mL/min/m2, and no risk factors of rapid disease progression. Participants were randomized in a 1:1 ratio by a computer-generated random number table into metformin + standard of care group (metformin arm) and standard of care group (Control arm). Primary outcome of the study was to evaluate the effects of metformin versus control arm on the percentage and absolute change in eGFR over a 6-month period.

Results:

Mean (SD) age of the cohort was 37.15 (10.16) years with half of them being females. The mean (SD) baseline htTKV and eGFR were 335.67 (153.3) mL/m and 100.23 (25.95) mL/min/m2, respectively. Clinical exome sequencing was available in nine (17.3%) patients of which two-thirds had PKD1 mutation. Baseline characteristics were distributed equally across randomized groups. Baseline proteinuria was significantly higher in the metformin arm (p = 0.014). The eGFR difference and percentage change in eGFR was not different between the groups at 6 months (p = 0.53 and 0.48, respectively). There was no statistically significant difference in htTKV and percentage change in htTKV at 6 months between the groups, although an increase in htTKV was numerically smaller in the metformin group (p = 0.769, 0.805). Blood pressure, body weight, body mass index (BMI), and proteinuria also did not differ between the two groups. Only half of the cohort tolerated the maximum dose of metformin. Around two-thirds of patients reported adverse effects, most commonly asthenia.

Conclusion:

Metformin appears to be safe and well tolerated in nondiabetic patients with ADPKD.

Introduction:

Discovering predictors to reduce morbidity and mortality in chronic kidney disease (CKD) is now a critical global priority. Serum phosphate level is considered to be a potential marker for mortality rate in patients with CKD. Previous studies examined the independent pathogenic role of phosphorus in the development of CKD and dialysis patients but have yielded contradictory findings. This study aims at evaluating the relationship between serum phosphate levels and death rates in pre-dialysis CKD and maintenance of dialysis patients.

Method:

PubMed, Scopus, and Web of Science were searched by using MeSH term keywords. The authors did screening, data extraction, and quality assessment in accordance with the inclusion criteria. STATA 14.2 was used for statistical analyses. The analysis was performed using the random- and fixed-effects model when the heterogeneity was >50% and ≤50%, respectively. For evaluating publication bias, Funnel plots and Egger tests were used.

Result:

Eleven original studies between 2005 and 2021 met the eligibility criteria. The overall estimate of unadjusted HR of all-cause mortality each 1 mg/dL increase in the serum phosphate concentration using the random-effects model in pre-dialysis CKD and dialysis patients was 1.33 (95% CI: 0.97, 1.82, I2 = 99.1%, P = 0.074), and for adjustment, Hazard ratio was 1.27 (95% CI: 1.15, 1.39, I2 = 75.4%, P < 0.001).

Conclusion:

The findings showed the association between serum phosphate levels and death rates in pre-dialysis individuals with CKD and dialysis patients.

Authors: Хатков К.Х. , Морозов А.В. , Морозова Е.С.
Published: August 2024

Многолетние почвенные исследования и агрохимическая оценка сельскохозяйственных угодий Республики Адыгея показывают незначительную, но устойчивую тенденцию к снижению потенциального плодородия почв (содержание гумуса) и, соответственно, к ухудшению качества почвенного покрова. За каждый тур агрохимического обследования сельскохозяйственных угодий Республики Адыгея содержание гумуса в почве снижается в среднем на 0,068%, что составляет 0,014 % в год свидетельствует о развитии процессов дегумификации.

Long-term soil research and agrochemical assessment of agricultural land in the Republic of Adygea shows a slight but steady trend towards a decrease in potential soil fertility (humus content) and, accordingly, a deterioration in the quality of soil cover. For each round of agrochemical survey of agricultural land in the Republic of Adygea, the humus content in the soil decreases by an average of 0,0679%, which is 0,01358% per year, which indicates the development of dehumification processes.

В статье рассматривается алгоритм дифференциальной эволюции и определяются целевые характеристики, повышение которых является актуальной задачей. Предлагается ряд подходов к модернизации алгоритма дифференциальной эволюции, которые, согласно выдвинутым в работе гипотезам, позволят повысить значения целевых характеристик. Предложенные подходы разработаны на основе результатов современных исследований в области эволюционной биологии. Они представляют собой моделирование биологических процессов, которые, по мнению ряда исследователей, ускоряют эволюционный процесс в биологических системах. Моделируемые биологические процессы связаны, в том числе, с такими объектами исследования эволюционной биологии, как репарация ДНК, взаимосвязь между генотипом и фенотипом, синергетический эффект отрицательных мутаций, а также взаимодействие в системе «хищник-жертва», формализуемое математической моделью Лотки-Вольтерры. Приводятся общие рассуждения о постановке вычислительных экспериментов для проверки выдвинутых гипотез.
