Published: January 2023

Abstract This is a narrative review whose objective is to understand the state of the art of the literature on Community Health Worker (CHW) programs worldwide, identifying their nomenclatures, practices, training, and working conditions. The major concentration of CHW programs can still be found in low- and middle-income countries in Africa (18), Asia (12), and Latin America (05), with a few experiences in high-income countries in North America (02) and Oceania (01). In total, 38 experiences were cataloged, and the practices of care, surveillance, education, health communication, administrative practices, intersectoral articulation, and social mobilization were described. The levels and duration of CHW training were characterized, as were the different working conditions in each country. Much of the work is precarious, often voluntary and carried out by women. This review provided a comparative overview that can contribute to enrich the view of managers and decision-makers in contexts of the implementation, expansion, and reconfiguration of such programs.

Resumo A queda de coberturas vacinais (CV) na infância, entre elas a da poliomielite, vem se tornando uma preocupação sanitária. O objetivo foi analisar a tendência temporal das coberturas das três doses da vacina contra a poliomielite nos primeiros 12 meses de vida entre 2011 e 2021, com destaque na pandemia de COVID-19, além de mapear as CV no Brasil. Foi realizado um estudo ecológico com técnicas de série temporal interrompida (STI) e análise espacial, a partir dos dados do Sistema de Informação do Programa Nacional de Imunização. A tendência da CV foi ajustada pelo estimador de variância de Newey-West, segundo as unidades federadas e o Índice de Privação Brasileiro. A distribuição da CV foi estimada por modelos bayesianos e os aglomerados espaciais pelos índices de Moran global e local, identificando áreas de menor cobertura nas Regiões de Saúde. Observa-se perda da CV ao longo do período em todas as regiões do país, sendo maiores no Norte e no Nordeste e se acentuando durante a pandemia. As maiores quedas foram identificadas em estados e regiões de saúde com maior vulnerabilidade social. A queda na CV mostra que o risco de reintrodução do vírus selvagem é iminente e os desafios precisam ser enfrentados com o fortalecimento do Sistema Único de Saúde.

Abstract The re-emergence of vaccine-preventable diseases due to the decline in vaccine coverage (VC) has been documented in several countries. The objective was to analyze the VC, the homogeneity of VC, and measles cases in Brazil from 2011 to 2021, focusing on the period of the COVID-19 pandemic, its temporal trend, space-time distribution, and factors associated with clusters of lower VC. This is an ecological study on measles VC (dose 1), with methods of interrupted time series and evaluation of spatio-temporal disposition, through the sweep test to identify clusters of VC. Starting in 2015, we observe a progressive decline in VC and homogeneity, with an accentuation after 2020, in all regions, particularly in the North and Northeast. Low VC clusters were associated with worse human development indicators, social inequality, and less access to the Family Health Strategy. In Brazil, the pandemic intensified health inequalities with low VC of measles in socially more vulnerable and unequal municipalities. There is a risk of virus circulation, however, the challenge of strengthening primary care, improving health communication and guaranteeing access to the vaccine, reducing missed opportunities for vaccination and vaccine hesitancy, is highlighted.

Published: January 2023

ABSTRACT: Isoimmune thrombocytopenic purpura (ITP) is an immune-mediated disease that causes severe hemorrhagic lesions and high mortality in piglets. The disease can occur early in newborn piglets (EITP) or late in 2- to 3-week old piglets (LITP). In this study, we analysed the clinical, pathological, and hematological aspects of 391 ITP cases (312 with EITP and 79 with LITP). In LIPT cases, morbidity and mortality rates were higher, with rates of 60% (morbidity) and 53% (mortality). The main clinicopathological findings in ITP cases were different patterns of hemorrhages organs and tissues. In EITP, clinical signs were characterized by extensive subcutaneous hemorrhages and death occurred within a few days; however, in LITP, often sudden death occurred. In macroscopic analysis, hemorrhagic diathesis was observed in all affected animals. In EITP, the most severe hemorrhagic lesions were integumentary, mainly in the dermis and epidermis. In LITP, visceral lesions were predominant, mainly in the epicardium and intestines. Microscopic bone marrow analysis revealed mild cellular hyperplasia in EITP and bone marrow aplasia in LITP. hematological analyses revealed leucopenia, thrombocytopenia, and anemia in all ITP-affected animals. However, fostering by a different sow was only efficient in controlling EITP and had little effect in LITP-symptomatic piglets, due to more severe lesions. Further studies on the etiopathogenesis of LITP are required to improve our understanding of this disease form.

ABSTRACT: Toxoplasma gondii can be eliminated in bovine semen. Cryopreserved semen is often used due to the fact that artificial insemination in dairy and beef cattle provides benefits in terms of production. However, little is known regarding the viability and infectivity of T. gondii tachyzoites in cryopreserved bovine semen. In the present study, cattle semen negative for T. gondii were contaminated with 1 x 106 tachyzoites (RH strain) and cryopreserved with and without different cryoprotectants, such as DMSO (concentrations of 2.5%, 5.0%, 7.5%, 8.0% and 10.0%) and glycerol (2.25%, 2.5%, 3.0%, 5.0%, 7.5% and 10.0%), followed by freezing in liquid nitrogen (-196°C). After 24 hours, the samples were thawed and inoculated in 10 mice per cryoprotectant concentration. The mice were evaluated for clinical signs of toxoplasmosis (rough coat, diarrhea, hypoactivity and sudden death) as well as serum titers of IgM and IgG and the presence of tachyzoites in the peritoneal lavage. The results revealed that T. gondii remained infective in all samples. Clinical signs of toxoplasmosis were observed in the mice beginning with the 6th day post-inoculation (DPI) and 100% lethality was found between the 7th and 9th DPI. Viable tachyzoites were recovered from peritoneal exudate of dead mice (except for the control group), with higher mean of tachyzoite counts in the intraperitoneal lavage for 5% DMSO (±3.32 x 106), 8% DMSO (±3.53 x 106), 3% glycerol (±4.75 x 106), 7.5% glycerol (±6.26 x 106) and the absence of cryoprotectant (±3.11 x 106). Seroconversion occurred in the treated groups, with titers of IgG from 1:16 to 1:128 and IgM from 1:16 to 1:512. T. gondii viability and infectivity were maintained in cattle semen during 24 hours of cryopreservation at -196°C with and without cryoprotectant. However, further studies are necessary to determine whether cryopreserved semen contributes to the spread of toxoplasmosis through artificial insemination.
Sharing representations in the relations between business proposals, consumption visions, and government policies
Authors: Melo Paulo Thiago N. B. de , Cambrainha Géssika Maria G. , Gómez Carla Regina P.
Published: January 2023

ABSTRACT Purpose: This theoretical essay aims to explore sustainable consumption, emphasizing the sharing of representations with business proposals and government policies. Originality/value: Through consumption, gains in quality of life and forms of social insertion are created by social businesses. Studies on social representations can indicate the sharing of views between different social actors, such as companies, governments and consumers. The text continues with a discussion on the theory of social representations and the dynamics of sustainable consumption. Social representations guide the views, actions, and attitudes of individuals, including when it comes to insertion in the dynamics of consumption. Subsequently, business proposals for the base of the pyramid are highlighted, discussing different possible scenarios for their relationships with consumers and government policies. Design/methodology/approach: The theoretical essay is characterized by the development of theory as a conceptual production, in which logic takes the place of data for evaluation and elaboration of propositions. Findings: A greater or lesser sharing of representations allows for the design of different possible scenarios for the relationships between consumers with a moralistic or hedonistic vision, social or traditional business proposals, and governments with policies for sustainable or spurious development. Finally, propositions about the existence of gaps between the representations of the needs of consumers oriented towards sustainable development, value propositions of social businesses, and government instruments in emerging markets are mentioned.
Neoliberalism and active aging: The role of business retirement preparation programs
Authors: Bernardinelli Ingrid , Candido Silvio E. A. , Tonelli Maria J.
Published: January 2023

ABSTRACT Purpose: To analyze the relationship between the rise of the retirement preparation programs (RPP) and the transformations in the ideological environment of organizations associated with the advent of the spirit of neoliberal capitalism. Originality/value: Few studies of Brazilian literature have addressed the dissemination of RPP from critical perspectives and, especially, in the business environment. Most of the research has addressed public institutions. Concerning international literature, the article innovates by associating the rise of the idea of active aging with the thesis of the new spirit of capitalism, developed by Luc Boltanski and Ève Chiapello. Unlike existing international studies, the analysis focuses on RPP as instruments for disseminating the dominant order in the organizational sphere. Design/methodology/approach: To meet the proposed objectives, qualitative research was carried out. Data were collected from nine informants from five consultancies that work in the structuring of corporate RPP and two companies that have recently structured their programs. A thematic content analysis was performed. Findings: The results reveal that the developed RPP promote conceptions of active aging in line with the new spirit of capitalism and changes in the forms of work organization driven by neoliberalism, which made it possible to conceptualize RPP as an object that incorporates and facilitates the diffusion of active aging and constructing an active retirement. The study advances in the understanding of the implications of new discourses on old age for organizations and stimulates a more critical comprehensionof RPP in public and private organizations.
Uma apreciação crítica da abordagem de caráter científico dominante da justiça organizacional

Published: January 2023

Resumo Objetivo: A proposta deste artigo é apresentar uma apreciação crítica da noção de justiça encapsulada na abordagem de caráter científico-social dominante da justiça organizacional (JO). O argumento que pretendemos endereçar aqui é: o distanciamento de noções prescritivas de justiça, recorrente na abordagem dominante da JO, reduz o ideal de justiça a um meio à disposição das organizações na busca de seus próprios interesses. Originalidade/valor: A possibilidade de desencadear na academia brasileira de administração uma discussão crítica sobre o instrumentalismo e o gerencialismo presentes na produção de conhecimento no campo da JO. Este trabalho contribui para uma reflexão sobre o ideal de justiça nas organizações. Design/metodologia/abordagem: Este é um texto teórico, cuja reflexão se assenta na consulta e na interpretação articulada de material bibliográfico relacionado à concepção hegemônica da JO, obtido por meio de revisão de literatura. Resultados: Um levantamento na literatura de JO revela uma postura de desprendimento assumida pela abordagem dominante em relação às concepções normativas de justiça. Por conta disso, a noção de justiça assumiu um caráter descritivo, subjetivo, funcionalista e positivista. Como categoria analítico-empírica, a justiça é concebida e compreendida por sua função instrumental-gerencialista dentro da estrutura organizacional. Como consequência, os estudos de justiça nas organizações têm sido acusados de converter o ideal de justiça em um recurso servil à prerrogativa da estratégia e do desempenho organizacional. De fato, esse distanciamento anulou e desperdiçou o valor do significado normativo desse ideal.
Digital twins as enablers of structure inspection and maintenance
Authors: Menegon Julia , Isatto Eduardo Luís
Published: January 2023

Abstract: The emergence of new technologies based on the exchange of data and information via the internet has prompted a revolution in the industry as a whole. First applied in manufacturing, the movement known as the Fourth Industrial Revolution soon spread and changed the dynamics of many other fields. Digital twins (DTs), one of the technologies that emerged in this scenario, are used to replicate physical environments in virtual models. Such models must be supplied with up-to-date information throughout a product's lifecycle to ensure accurate representation of the real asset. DTs have great potential to impact the construction industry, supporting facilities management, simulation tasks, and centralized management and recording of interventions. However, despite the attention the theme has attracted among researchers and companies, implementation of the concept in practical situations is still largely underexplored. Thus, this study aims to critically analyze the concept of DTs and their potential in the construction industry, particularly in inspection and maintenance tasks for existing structures. The study comprises a literature review undertaken to identify the multiple types of DT models, examine barriers and opportunities associated with their use, and discuss their potential as enablers of inspection and maintenance strategies. Furthermore, research opportunities related to the use of DTs for structural inspection and maintenance are suggested.
Aporte institucional das Instituições de Ensino Superior aos Editores de Periódicos Científicos
Authors: Werlang Elisabete , Blattmann Ursula
Published: January 2023

RESUMO As instituições de ensino superior públicas são responsáveis pela edição da maioria dos periódicos científicos no Brasil. Os professores dos programas de pós-graduação realizam voluntariamente a gestão do fluxo editorial. Este artigo discute o aporte institucional em termos financeiros, humanos, físicos e tecnológicos recebidos pelos editores, necessários ao atendimento das boas práticas editoriais. É uma pesquisa de natureza aplicada, com fins exploratórios e descritivos, realizada com 95 editores vinculados à Associação Brasileira de Editores Científicos. Os resultados obtidos apontam as lacunas existentes no aporte institucional recebido, principalmente quanto ao estabelecimento de critérios técnicos para a seleção, permanência e renovação do editor; à preservação digital; à insuficiência dos recursos financeiros para a autossustentação dos periódicos e até mesmo em relação à própria formalização dos periódicos junto às instituições editoras. As conclusões evidenciam que parte das necessidades dos editores não é suprida por uma questão de responsabilidade dupla: de um lado os editores, que iniciam esta atividade sem formação ou capacitação na área editorial, o que os deixa vulneráveis às próprias intempéries da função; de outro, as próprias instituições que, por não possuírem um enquadramento específico para a função, sofrem dos mesmos problemas de desconhecimento do aporte institucional necessário à editoria científica.

RESUMO Neste artigo é discutida a etimologia do conceito de abertura dentro do campo científico a partir do movimento de acesso aberto e do movimento de ciência aberta. Trata da abertura científica a partir da publicação aberta, que constrói um novo modelo de documento a partir da cultura digital e outros modos de compartilhamento, revisão por pares e participação mais efetiva da sociedade. Apresenta a mudança do conceito etimológico de accountability em ciência e como colabora para a governança cidadã. Debate a questão do impacto da abertura na responsabilidade pública da ciência, como amplia a autonomia social em educação científica e a consolidação de outros modelos de avaliação e validação da ciência. A metodologia aplicada consiste em uma pesquisa bibliográfica nas principais bases de dados científicas com recorte temporal entre os anos de 2002 e 2020 a partir dos principais termos presentes na literatura sobre o acesso aberto e ciência aberta que permitiu a análise conceitual evolutiva dos termos estudados. Conclui-se que está sendo construído um “novo contrato social para ciência” pautado na abertura dos processos científicos, possibilitando a difusão das inovações científicas e dados subjacentes e desenvolvendo práticas que equalizem o conhecimento dos não-cientistas com o dos cientistas.

Published: January 2023

RESUMO O artigo, ora apresentado, tem como objetivo aferir como os instrumentos de gestão são referenciados na legislação brasileira, nos âmbitos do Poder Executivo nacional e estaduais. A metodologia empregada nessa pesquisa foi a qualitativa em que se buscou, inicialmente, definir os conceitos e usos apresentados na bibliografia nacional e internacional sobre os instrumentos de gestão de documentos, a saber, plano de classificação e tabela de temporalidade e destinação de documentos. Adotou-se o estudo de multicasos comparados visando, a partir da legislação federal, mais precisamente a partir da Constituição Federal de 1988 e da Lei Federal n° 8.159 de 1991, analisar como os arquivos públicos do Poder Executivo Estadual conceituam e aplicam os instrumentos de gestão de documentos. Utilizou-se da pesquisa documental com o intuito de verificar na legislação a existência dos conceitos dos instrumentos; a determinação de sua elaboração e utilização; o estabelecimento dos procedimentos de produção e responsabilidade das suas respectivas aprovações. Na legislação arquivística do Brasil, nossos resultados permitiram afirmar que houve grande avanço nos últimos anos, no que se refere aos instrumentos de gestão, entretanto, em uma visão geral, o cenário ainda parece aquém do ideal, visto que ainda não se pode contar com uma política arquivística de âmbito nacional, e nem estadual, já que os planos de classificação e as tabelas de temporalidade e destinação de documentos nem sempre são aplicados e utilizados de forma sistemática na administração pública.

Published: January 2023

ABSTRACT Owing to the high prices of agricultural inputs, it is necessary to seek alternatives that minimize costs during the seedling production stage, such as the use of agro-industrial residues to formulate substrates and the application of humic substances to increase the availability of nutrients. This study aimed to evaluate the production of yellow passion fruit seedlings in substrates based on carnauba bagana under increasing doses of humic substances. The design was completely randomized, in a 3 x 4 factorial scheme, referring to three substrates formulated with carnauba bagana (0, 50 and 100 %) plus soil and four doses of humic substances (0, 12.5, 25 and 50 g L-1). The use of carnauba bagana in the substrate increased the leaf area, plant height, stem diameter, root length, root volume, shoot and root dry mass, and improved the seedlings quality. The application of humic substances to the substrate did not stimulate the seedlings development.

Published: January 2023

ABSTRACT The management of nematode infested areas includes several measures, among which chemical nematicides are the most used. However, since their use is associated with environmental impacts, researches with biocontrol agents have acquired a greater importance. This study aimed to evaluate the performance of Bacillus subtilis + B. licheniformis, when applied to the planting furrow, on nematode control and its effects on sugarcane yield. Five experiments were carried out in infested areas, with four treatments: control - no nematicide; carbosulfan 700EC 4 L ha-1 - standard treatment; B. subtilis + B. licheniformis at 0.16 kg ha-1 and 0.20 kg ha-1. Carbosulfan was more efficient in controlling the nematodes, reducing the populations at least four months after planting. The treatments with B. subtilis + B. licheniformis were more effective in the control of Meloidogyne javanica, when compared to Pratylenchus. The plots treated with carbosulfan produced 11 % more than the control. There was no difference between the B. subtilis + B. licheniformis doses, in relation to yield. The plots treated with the biological product produced 5 % more than the control.
Concrete modeling using micromechanical multiphase models and multiscale analysis
Authors: Silva Rodrigo Mero Sarmento da , Barboza Aline da Silva Ramos
Published: January 2023

abstract: Concrete in its macrostructure is a multiphase cementitious composite material, however, by reducing its scale, it is possible to identify the phases that compose it, among the phases are those embedded in the microscale: the hydrated silicates, in the mesoscale: the cement paste, transition zones and aggregates and in the macro phase: the composite itself. Modeling this type of material with two-phase micromechanical models is common in the literature, but there are already proven limitations that two-phase models can provide high modeling errors and are not recommended for this type of study. Faced with this problem, an alternative would be to use multiple-phase models, combined with a multiscale perspective in an attempt to minimize the error in modeling this material. The present paper models the concrete in two different constructions: without an interfacial transition zone and with the inclusion of the interfacial transition zone, verifying the modeling error when neglecting this important phase. The entire homogenization process is performed using the decoupled multiscale technique, obtaining results that rule out the use of two-phase models and methodologies that do not evaluate the interfacial transition zone in conventional concrete. The results obtained with the use of multiple-phase models reduced the relative error to practically zero (compared to experimental tests), demonstrating that micromechanics can be a concrete modeling tool provided that the multiscale process considers as many as possible phases and robust models that take this nature into account.
Damage and plasticity evolution of reinforced concrete beams using laminated Euler-Bernoulli finite elements
Authors: Imai Ana Paula , de Oliveira Abeche Thiago , Machado Roberto Dalledone
Published: January 2023

abstract: This paper analyses the behaviour of reinforced concrete beams subjected to progressive loads. Although this topic is addressed in recent works through tri-dimensional finite elements, the present study adopts a simpler alternative, using Euler-Bernoulli’s beam finite element. The evolution of the generalized cracking is addressed by Damage Mechanics theory, and the nonlinear constitutive models of concrete and steel are considered, including plasticity and post-peak ‘. The laminated approach permits not only to ascertain the damage evolution but, in practical aspects, makes easy to define vertically symmetrical transversal sections and to distribute the reinforcement as desired, even if the steel rebars have different lengths. It is highlighted the changing of the neutral axis during the damage evolution process, which is updated automatically by the developed numeric-computational code. To validate the proposed methodology, two examples are detailed, both based on experimental tests found in the literature. The results obtained are close to the experimental ones and confirm the applicability of the proposed approach.
Influence of shear walls on the structural behavior of a multi-storey concrete building according to Brazilian Technical Code ABNT NBR 15421:2006
Authors: Seruti Carlos Alexandre , Lima Eduardo Fernandes , Lima Silvio de Souza , Santos Sergio Hampshire de Carvalho
Published: January 2023

abstract: This paper presents a comparative study of the influence of shear walls on the behavior of a multi-storey concrete building when subjected to seismic actions. Two structures with different earthquake-resistant systems were evaluated. One is composed of concrete frames with usual detailing in both directions (x and y), and the other one is formed by a dual system, composed of frames and shear walls with usual detailing. The Equivalent Lateral Force procedure and the Modal Response Spectrum analysis presented by the Brazilian Technical Code ABNT NBR 15421:2006 were considered. The dual system building presented a greater stiffness with the shear walls arranged parallel to direction y. In the x direction, the responses are equivalent in both buildings. The horizontal forces obtained by the Equivalent Lateral Force method at the base of the buildings were greater than the Modal Response Spectrum method.
Data-driven spatio-temporal analysis of consolidation for rapid reclamation
Authors: Shi Chao , Wang Yu
Published: January 2023

Spatial extension of lands through rapid reclamation is attractive for congested coastal megacities, although reclamations might suffer from project delay and budget overrun, often due to encountering unforeseen ground conditions. To accelerate reclamations, accurate prediction of soil consolidation over a construction duration of multiple years is needed for reclaimed lands, which often contain spatially varying subsurface stratigraphy and soil parameters. This calls for a spatio-temporal analysis of consolidation with a sound understanding of subsurface stratigraphic alternations of fine/coarse-grained soils and spatial variability of consolidation parameters (e.g. permeability). In this study, a unified framework, capable of simultaneously modelling stratigraphic variation and spatial variability of soil properties through machine learning of limited site investigation data, is combined with the finite-element method and Monte Carlo simulation for spatio-temporal consolidation analysis of reclaimed lands. The proposed method is applied to a real reclamation project in Hong Kong. Results indicate that the proposed method can accurately characterise subsurface geological cross-sections and spatially varying soil permeability with quantified uncertainty. Ignorance of spatial variability of soil permeability may result in an underestimation of consolidation time and an overestimation of undrained shear strength gain, and thus pose significant risks to reclamation projects.

Maintaining the employability of employees: gradual reintegration in a large German chemical company Objectives: Gradual reintegration is a measure in the return-to-work process and is part of the occupational health management at BASF SE, which is the responsibility of Corporate Health Management. This article aims to describe the gradual reintegration of employees of BASF SE in Ludwigshafen in the years 2016 to 2021. Methods: Data on the start and end of the gradual reintegration, the results of reintegration and the duration of previous incapacity for work, including relevant diagnoses, was entered into the electronic patient file (AMEDIS) by the responsible occupational physicians and supplemented by information on age, gender, working time system and occupational group as well as occupational health screening data on smoking status, weight and height. Results: From 2016 to 2021, 3260 gradual reintegrations were carried out on 2826 people at BASF SE’s main site in Ludwigshafen. The participants were on average 49 years old and 18 % were female. More than 90 % of the reintegrations were successfully completed (with or without health restrictions). Ill-health retirement was required for less than 1 % (n = 11). Participants were unable to work for 137 days (median; IQR: 92–218) prior to the start of reintegration. The most common diagnosis groups were mental and behavioural disorders and diseases of the musculoskeletal system, followed by cardiovascular diseases, injuries and cases of poisoning. A successful gradual reintegration took a median of 27 days (IQR: 23–40) to complete. Conclusions: Gradual reintegration is well established as a successful tool for maintaining employability after prolonged incapacity for work. Occupational physicians bring their knowledge of the jobs and the organisational structure within the company and are thus able to shape the gradual reintegration individually and according to requirements. Keywords: gradual reintegration – corporate integration management – incapacity for work – preservation of employability

In practice, the choice of the type of neural network is carried out empirically based on an experience of an investigator and many training attempts. At the same time, the excessive complexity of the neural network leads to an increase in its training time, and in some cases, to the impossibility of learning at all. Thus, the justification of the choice of an artificial neural network structure and/or its preliminary calculation based on other models is an urgent task. An equally important task is the choice of an initial weighting coefficients of an neural network, the choice of which determines the speed of convergence of search algorithms. This paper demonstrates several approaches to solving the problem of choosing an architecture and initializing a weighting coefficients of a neural network. One of them is carried out on the basis of a previously calculated function using Petri nets. This approach is demonstrated for solving various tasks, which include the implementation of functions using previously defined neural network models of the simplest logical operations "and", "or", etc. An approach is given that allows optimizing an architecture of a neural network that solves the problem of approximating functions of one and several variables. The principle of determining an architecture and initial weight coefficients is also used in the tasks of training neural networks with reinforcement. A separate section is devoted to the formation of a methodology for determining an architecture and initialization of a weighting coefficients of a neural network of the controller based on information about the controller obtained by a modal method using a polynomial matrix decomposition of a system. The problem of synthesis of a neural network controller for an object model containing nonlinearities and nonparametric uncertainties in the control channel is solved.
A Cracked Public Administration in Peru: How “Vacunagate” Has Shaken the Foundations of an Already Damaged Society
Authors: Briolo Carlos , Cordova Miguel
Published: January 2023

While crises are ubiquitous in Latin America, due to its geographical characteristics as well as its turbulent business environment, countries such as Peru have also extreme rates of corruption and deep institutional weakness. These factors, taken together, undermine any attempt of national governments or society’s collective efforts towards achieving sustainability. This paper aims to analyze the “Vacunagate” scandal that occurred in Peru during the first negotiations of the vaccination process against COVID-19, using a case study method, and focusing our discussion from the Agency Theory as well as from leadership and institutional perspectives. The results of the analysis emphasize how the “Vacunagate” event generated relevant constraints towards the achievement of the SDG 16, and its specific targets related to provide justice for all, deal with organized crime, reduce corruption, and create accountable institutions. In addition, the study provides insights and implications for organizations in Peru that would have to operate under a turbulent business environment, considering a business-as-usual corruption and a weak institutional context.
Сетевые СМИ и политическое управление в современном Таджикистане
Authors: Салимов Диловар Мирзомуддинович
Published: January 2023

В статье анализируется роль сетевых СМИ в политическом управлении в современном Таджикистане. Определяются коммуникационные факторы политического управления, выступающие механизмом адаптации политической системы к социальной среде и являющиеся принципиально важным условием осуществления современных управленческих процессов. Анализируется процесс формирования сетевых СМИ, сетевого сообщества и их влияние на ход политического управления в стране. Предлагается анализ ряда политически важных документов и процесс их легитимации как следствие публичного дискурса в сетевых СМИ. Проведенный анализ позволяет автору сделать вывод о том, что в стране наиболее динамично развивающимся видом коммуникации выступает именно сетевая политическая коммуникация, которая привела к изменению стиля политической журналистики и формированию принципиально новых форм влияния на субъекты политического управления. Данный фактор образуется одновременно с формированием идеологического объединения власти и сетевых СМИ, основанного на публичном обсуждении значимых для общества вопросов для нахождения путей их решений в целях стабилизации общественной и политической ситуации. При этом учитывается и то, что функционирование сетевых СМИ определяется законодательством страны, что, наряду с традиционными СМИ, увеличивает вероятность их попадания в сферу влияния системы цензуры и контроля.

Private and public sector companies are suffering cyber attacks globally, so the need to invest in cybersecurity has become a priority. In this sense, several supervisors have formulated regulations around cybersecurity, with a particular emphasis on banks and their challenges but not much on the Stockbrokers (SBK) entities that are the subject of this research work. Although one of the most common methodologies is the simulation of offensive (red team) and defensive (blue team) security, purple teams are emerging as an alternative that enables a broader spectrum of learning and analysis for companies, particularly SBKs This article details a methodological guide for the design and implementation of a purple team in SBKs in order to strengthen cybersecurity governance in the face of contemporary cyber threats.

We evaluated and compared the performance of simulated Angström-Prescott (AP) and Hargreaves-Samani (HS) models on monthly and annual timescales using generalized datasets covering the entire West African region. The fitted AP model yielded more efficient parameters of a = 0.366 and b = 0.459, whereas the HS model produced a 0.216 coefficient based on an annual timescale, which is more suitable in the region compared to coefficients recommended by the Food and Agriculture Organization (FAO) (a = 0.25 and b = 0.5) and HS (0.17), respectively. Employing the FAO and HS recommended coefficients will introduce a relative percentage error (RPE) of 18.388% and 27.19% compared to the RPEs of 0.0014% and 0.1036% obtained in this study, respectively. When considering time and resource availability in the absence of ground-measured datasets, the coefficients obtained in this study can be used for predicting global solar radiation within the region. According to the AP and HS coefficients, the polycrystalline module (p-Si) is more reliable than the monocrystalline module (m-Si) because the p-Si module has a higher tendency to withstand the high temperatures projected to affect the region due to its higher intrinsic properties based on the AP and HS coefficients assessment in the region.
Health consequences and control of the use of information and communication technologies by children and adolescents: literature review
Authors: Ivanova Larisa Yu.
Published: January 2023

The review reflects publications in the field of medicine, psychology and sociology, covering: the negative impact of the uncontrolled use of information and communication technologies on the health of the child and adolescent population in the broad sense of the term health, covering not only physical, but also psychological, and social well-being. The results of medical observations and psychological research indicate that digital technologies have become a significant factor affecting the health of children and adolescents, the development of their cognitive functions, emotional and social development. Mass surveys have revealed an increase in the duration of daily use of digital devices and the Internet by the younger generation, a significant part of the surveyed adolescents are now classified as abusers of computer games and the Internet, there is also a category of users with signs of forming or developing dependence on computer games and the Internet. Considering that communication in social networks takes a significant share of the younger generations time, influencing the user, the review reflects studies of the peculiarities of communication between adolescents and young people in social networks. Taking into account that the use of electronic learning tools creates a burden on students, studies are highlighted that raise the issue of comparing the effectiveness of using digital learning tools relative to traditional forms of learning. It is well known that parental control of the use of communication technologies by children is a condition for preserving their health. Surveys show insufficient competence of parents in this matter. There is a need for sociological research of parents ideas about the specifics of the risks of using digital technologies for the health of children and adolescents of different ages, educating the population about these risks, especially the risks to the health of children of early and preschool age.
