Balance de la política pública de inteligencia artificial y transformación digital (2019-2024)
Authors: Vargas Aguirre Camilo 
Published: September 2024

Objective. To review the contents and implementation of CONPES 3975 of 2019 on artificial intelligence (AI) and other public policy initiatives aimed at digital transformation. Methodology. A public policy evaluation scheme is proposed based on the recommendations of the CAF country self-assessment (2024) and a review of the evaluation methodologies used in Colombia. Results. The discussion on public policies on artificial intelligence and digital transformation, as well as the role of the State in their adoption, has focused on the relevance of a national regulatory scheme. In academia, the regulation of the use and deployment of automated decision systems (ADS) by state entities at the national and local levels and in the judicial branch is debated. However, little attention has been paid to the instruments and mechanisms for monitoring existing public policies in AI and digital transformation, which have positioned Colombia as a pioneer country in these areas.The lack of evaluation, continuity and improvement of these policies puts this leadership at risk. Conclusion. It was identified that the country has effective regulatory tools, implementations and monitoring mechanisms, although there is also evidence of a lack of continuity in the development of public policies on AI and digital transformation. An evaluation agenda is proposed to address this deficiency.

Published: September 2024

Cashless payment systems have emerged as a transformative force in the global financial landscape, offering convenience and efficiency in transactions. Despite their widespread development, the adoption of these systems has been uneven, with only a select number of companies in specific countries making notable progress. This research investigated the correlation between perceived financial value and the adoption of cashless payment systems in Nairobi's Matatu sector. The central question was how perceived financial value influences this adoption. This research was grounded on institutional theory, the study used an explanatory research design with a target population of 1,176 Matatu SACCO managers and staff, from which a sample of 289 was selected using stratified and simple random sampling. Data was collected via a questionnaire, with validity assessed through Pearson Moment Correlation and reliability through the test-retest method. Quantitative analysis was conducted using SPSS. The findings revealed a significant impact of perceived financial value on cashless payment adoption (β=0.534, t=10.744, p<0.05) and a 67.9% positive correlation. The study concluded that a suitable legal and institutional framework is needed, requiring collaboration between the private and public sectors to support technological adoption among Matatu operators in Nairobi. In light of the study's findings, the researchers recommended that the lack of a suitable legal and institutional framework for e-payments necessitates a joint effort from both the private and public sectors to establish the necessary legal and institutional structures, thereby fostering an environment conducive to technology integration among Matatu operators in Nairobi and beyond.
Afrosalsola (Amaranthaceae-Chenopodiaceae), an intermediate C3-C4 lineage from NW Africa and the Canary Islands, and some new combinations in African species of Caroxylon and Soda
Authors: Akhani Hossein , Abdullahi Hussaini , Rudov Alexander 
Published: September 2024

The segregation of the polyphyletic genus Salsola (Amaranthaceae-Chenopodiaceae) caused enormous nomenclatural changes during the last two decades. A lineage, that is still awaiting to be validated by a new valid name comprises four interesting taxa endemic to the Canary Islands and NW Africa. These are shrubby plants with opposite and alternate branches and leaves, specific leaf-anatomy with a hypodermis and Kranz-like cells performing a C3-C4 intermediate photosynthetic pathway (C2 type). The new genus Afrosalsola is described with the inclusion of 2 species [Afrosalsola divaricata (Mass. ex Link) Akhani comb. nov., and A. deschaseauxiana (Litard. & Maire) Akhani comb. nov.] and three subspecies of the former [Afrosalsola divaricata subsp. divaricata, A. divaricata subsp. verticillata (Schousboe) Akhani and A. divaricata subsp. gymnomaschala (Maire) Akhani]. The synonymy of Salsola deschaseauxiana Litard. & Maire with S. verticillata Mass. ex Link is rejected based on typical alternate leaves of the former. Salsola divaricata is typified based on its original collection in BM. Additional new combinations of African species belonging to Caroxylon and Soda are provided.

Introduction and objectiveThe role of immunoglobulin G antibodies in combating SARS-CoV-2 infection, modulation of COVID-19 disease severity, and persistence of humoral response after primary infection and
vaccination is unclear. This study aimed to evaluate the role of antibodies in limiting the infection, modulating disease severity, and determining the durability of the immune response depending on the clinical status of patients, their age, sex, and vaccination status.Material and methodsThe study involved 156 patients, 99 men and 57 women, aged 58.3 ± 12.5 years old, hospitalised for pneumonia in the course of COVID-19, with infection confirmed by real-time polymerase chain reaction test. The concentration of anti-SARS-CoV-2 IgG antibodies was tested at 3, 6, and 9 months from the day of hospitalisation.ResultsThe concentration of anti-SARS-CoV-2 IgG antibodies in patients with severe COVID-19 was higher compared to the group of patients with mild to moderate disease. The level of anti-SARS-CoV-2 IgG antibodies was comparable in men and women. In patients over 60 years of age, a lower concentration of antibodies was observed than in patients under 60 years of age. In the vaccinated group, the level of antibodies was higher than in the unvaccinated group.ConclusionsThe study findings showed that the concentration of IgG anti-SARS-CoV-2 antibodies was not a parameter dependent on the sex of the patients, but rather on the severity of the disease and the age of the patients and their vaccination status.

Sourdough bread produced using lactic acid bacteria (LAB) and yeasts offers numerous advantages. Such bread may exhibit prebiotic effects, positively affecting the gut microbiota and conferring a health benefit to the host. Furthermore, the use of LAB sourdoughs for breadmaking can improve product shelf life, flavour and nutritional properties as compared to the exclusive use of baker's yeast. In this context, as a first step to develop such a starter culture, we isolated spoilage bacteria and fungi from spoiled products and screened a large collection of LAB isolates (n=136) from various sources for their antagonistic activities against bread spoilage microorganisms.
Хлебполученный на основе закваски из молочнокислых бактерий (МКБ) обладает множеством преимуществ, о чем свидетельствуют различные исследования. Такой хлеб обладает пребиотическим действием, модулируя микробиоту и увеличивая количество полезных бактерий. Кроме того, использование закваски в хлебопекарном производстве может улучшить срок хранения, вкус и питательные качества по сравнению с использованием исключительно пекарских дрожжей. С целю создания такой закваски нами проведены исследования по выделению изолятов (n=136) молочнокислых бактерий. Для предварительного отбора выделенные микроорганизмы были проверены на антагонистическую активость против возбудителей порчи хлеба.

This paper presents the characterization of two gamma reference fields of 137Cs and 60Co sources at the Institute for Nuclear Science and Technology. The characterization of the fields in terms of gamma fluence Φ, mean energy, EΦ, kerma weighted mean energies, Eₖ, air kerma, Eair, were determined at various distances from the source center by Monte Carlo simulation using MCNP6. The air kerma results were compared with the measurements obtained by using a calibrated ionization chamber. The discrepancy between the simulated and measured air kerma was less than 4.5%. The scatterred component was also simulated and calculated. The results of both methods showed that the contribution of the scattered components to the gamma reference field is less than 3%. This contribution comply with the international standard criteria of ISO 4037 (<5%). The results confirmed that the characterization of the gamma reference field could be determined using the simulation code.

Published: September 2024

Inoculation is an essential metallurgical route for controlling solidification conditions of cast iron, consequently, in this study, the influence of varied percent ferrosilicon (FeSi) addition on microstructure and mechanical properties of grey cast iron (GCI) was investigated. A 50Kg capacity rotary furnace was used to melt the charge (Auto engine block scrap, graphite, ferrosilicon (FeSi) and limestone). The casting was produced in a greensand mold with wooden rectangular pattern of length 50 mm and breadth 30 mm. Chemical compositions and carbon equivalent values (CEVs) of the samples were determined, using Optical emission spectrometry (AR 4 metal analyzer) and the expression respectively. Microstructures of the samples were obtained, using metallurgical microscope (model number NJF-120A). The tensile and hardness properties were measured, using Universal tensile tester and Rockwell hardness tester respectively. From the results, C and Si were the major elements. Other trace elements were Mn, P, S and Al. CEVs of both the control and inoculated samples were less than 4.3%. Microstructure of the control sample was comprised of primary dendrites and graphite flakes, while those of the inoculated samples were characterized by varied amount of more developed primary dendrites, longer graphite flakes and austenite dendrites. Also, a number of small MnS particles were observed in relative amount within the microstructures. Tensile and hardness properties of the FeSi inoculated samples were superior to the control sample. Highest tensile strength and hardness values of 76.62 MPa and 99.89 HRB respectively were obtained at the optimum inoculation of 1.5 wt. % FeSi.
