Assessing job performance in brazilian digital government : the role of knowledge management systemsuse and social capital

Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Information Systems and Technologies ManagementDiante dos desafios do governo digital, esta pesquisa busca compreender os propulsores do desempenho laboral e organizacional na administração pública brasileira. Foi criado modelo de pósadoção para avaliar o desempenho da administração pública mediante a utilização de sistemas de gestão do conhecimento (KMS), com base nos conceitos de satisfação do usuário, uso enxuto de sistemas (duração, frequência e intensidade), capital social, e liderança transformacional. Após revisão de literatura sobre as teorias de liderança transformacional e capital social, foi analisado o impacto destes fatores contextuais no ambiente governamental de uma agência pública brasileira (Ministério do Meio Ambiente). Utilizando-se de abordagem empírica, a pesquisa recolheu dados de 295 funcionários públicos, após questionário on-line, e obteve como resultados que o desempenho individual no trabalho, usando KMS, afeta positivamente o desempenho da organização, sendo também impactado por fatores como intensidade do uso de KMS, satisfação do usuário e capital social. A satisfação do individuo impacta o desempenho individual, sendo afetada pela frequência e intensidade do uso do KMS, assim como pelo capital social, que desempenha relevante papel no desempenho individual e organizacional, ampliando o relacionamento entre a satisfação do usuário e o desempenho individual, vez que apresenta efeito moderador. O desempenho organizacional é influenciado pela liderança transformacional, responsável por moderar as conexões entre a performance individual e institucional. A pesquisa fornece informações relevantes para a literatura em sistemas de gestão do conhecimento, de forma a conectar o uso de KMS com a satisfação e o desempenho, elucidando a importância do capital social para o alcance de melhores resultados em ambientes governamentais.Faced with the challenges of digital government, this research seeks to clarify the drivers of individual and organizational performance in the Brazilian public administration. A post-adoption model was developed to evaluate the performance of public administration with knowledge management systems (KMS), given the concepts of user satisfaction, lean system use (duration, frequency and intensity), social capital, and transformational leadership. After literature review on theories of transformational leadership and social capital, the impact of these contextual factors on the government environment of a Brazilian public agency (Ministry of the Environment) was verified. Using an empirical approach, the survey collected data from 295 public officials, using online questionnaire, obtained as results that the individual performance at work, using KMS, positively affects the organizational performance, being also impacted by factors such as intensity of the KMS use, user satisfaction and social capital. User satisfaction impacts individual performance, being affected by the frequency and intensity of KMS use, as well as by social capital, which plays a relevant role in individual and organizational performances, amplifying the relationship between user satisfaction and individual performance, given its moderating effect. Organizational performance is influenced by transformational leadership, responsible for moderating the connections among individual and institutional performance. The research provided relevant information to the literature on KMS, to connect system use, satisfaction and performance, elucidating the importance of social capital to achieve better results in government contexts

Drivers of digital transformation adoption: A weight and meta-analysis

Cavalcanti, D. R., Oliveira, T., & Santini, F. D. O. (2022). Drivers of digital transformation adoption: A weight and meta-analysis. Heliyon, 8(2), 1-17. [e08911]. https://doi.org/10.1016/j.heliyon.2022.e08911 --------------------------- Funding: This work was supported by national funds through FCT (Fundação para a Ciência e a Tecnologia) under the project - UIDB/04152/2020 - Centro de Investigação em Gestão de Informação (MagIC).The advent of the global pandemic has accelerated the growing need for product and service transformation, highlighting the emerging importance of technology and creating the opportunity to update the digital transformation (DT) domain through empirical-quantitative research. This weight and meta-analysis enabled the synthesis and integration of previous literature on the scope of individual DT adoption, evaluating the state of the art and filling a void on the subject. Athwart 88 studies and 99 datasets by international sources, our results demonstrate that attitude and satisfaction are relevant predictors of behavioral intentions and promising outcomes, including compatibility and personal innovativeness. Behavioral intentions, satisfaction, and habit are the best predictors for DT use. Usefulness and ease of use are critical for DT adoption intention and use, being moderated by individualism, as a cultural factor, human capital, and knowledge-technology, as innovation indicators. We present a conceptual model of promising and best predictors for future research on DT individual adoption.publishersversionpublishe

Biosensors for studies on adhesion-mediated cellular responses to their microenvironment

Cells interact with their microenvironment by constantly sensing mechanical and chemical cues converting them into biochemical signals. These processes allow cells to respond and adapt to changes in their environment, and are crucial for most cellular functions. Understanding the mechanism underlying this complex interplay at the cell-matrix interface is of fundamental value to decipher key biochemical and mechanical factors regulating cell fate. The combination of material science and surface chemistry aided in the creation of controllable environments to study cell mechanosensing and mechanotransduction. Biologically inspired materials tailored with specific bioactive molecules, desired physical properties and tunable topography have emerged as suitable tools to study cell behavior. Among these materials, synthetic cell interfaces with built-in sensing capabilities are highly advantageous to measure biophysical and biochemical interaction between cells and their environment. In this review, we discuss the design of micro and nanostructured biomaterials engineered not only to mimic the structure, properties, and function of the cellular microenvironment, but also to obtain quantitative information on how cells sense and probe specific adhesive cues from the extracellular domain. This type of responsive biointerfaces provides a readout of mechanics, biochemistry, and electrical activity in real time allowing observation of cellular processes with molecular specificity. Specifically designed sensors based on advanced optical and electrochemical readout are discussed. We further provide an insight into the emerging role of multifunctional micro and nanosensors to control and monitor cell functions by means of material design.Fil: Saffioti, Nicolas Andres.

APRESENTAÇÃO

Mergulhar nos textos que compõem esta edição da Revista do InstitutoHistórico e Geográfico do Pará é lançar-se em um rizoma de afetos, na possibilidade de transcender as zonas de discussão que os integra e banhar-se nas linhas e entrelinhas. Os autores aqui reunidos, propuseram-se a escrever sobre experiências, análises, críticas, ensaios em intersecção com a temática "ESTÉTICA E POLÍTICA EM TEMPOS SOMBRIOS", reflexões sobre o momento atual em que vivemos de verdades ilusórias, de “Ilusões sem Ilusão” e de “Políticas apolíticas”, nesses tempos de crueldades melancólicas, em que não se desenvolvem mais projetos, vivemos em tempos de desilusões destrutivas

Resistencia a la aspirina: realidad o ficción?

A meta-analysis of clinical studies of patients with cardiovascular disease demonstrated that the use of aspirin was associated with a 22% decrease in death rates and relevant ischemic vascular events. However, clinical studies demonstrated that patients that regularly took aspirin presented recurrence of cardiovascular events. Such observation led to the question whether, in some patients, the aspirin was not effective in blocking platelet aggregation and these patients were called unresponsive to aspirin or aspirin-resistant. The clinical aspirin resistance is characterized as the occurrence of cardiovascular events in patients during treatment with aspirin, whereas the laboratory resistance is defined as the persistence of platelet aggregation, documented by laboratory test, in patients regularly taking aspirin. Patients that are aspirin-resistant presented, according to laboratory tests, on average 3.8 times more cardiovascular events when compared to non-resistant ones.Un metanálisis de estudios clínicos de pacientes con enfermedad cardiovascular demostró que el uso de aspirina estaba asociado a la reducción de 22% de muertes y a eventos vasculares isquémicos relevantes. Entre tanto, estudios clínicos revelaron que pacientes tomando regularmente aspirina presentaban recurrencia de eventos cardiovasculares. Tal constatación llevó a un cuestionamiento: si, en algunos pacientes, la aspirina no era eficaz en bloquear la agregación plaquetaria, siendo estos pacientes llamados de no responsivos o resistentes a la aspirina. Se conceptúa resistencia clínica a la aspirina por la ocurrencia de eventos cardiovasculares en pacientes en la vigencia del tratamiento con aspirina, mientras que la resistencia de laboratorio es definida como la persistencia de la agregación plaquetaria, documentada por test de laboratorio, en pacientes tomando regularmente aspirina. Pacientes resistentes a la aspirina tuvieron, de acuerdo con tests de laboratorio, en media, 3,8 veces más eventos cardiovasculares cuando fueron comparados a los no resistentes.Uma metanálise de estudos clínicos de pacientes com doença cardiovascular demonstrou que o uso de aspirina estava associado à redução de 22% de mortes e a eventos vasculares isquêmicos relevantes.

A Comparative Study of Randomized Constraint Solvers for Random-Symbolic Testing

The complexity of constraints is a major obstacle for constraint-based software verification. Automatic constraint solvers are fundamentally incomplete: input constraints often build on some undecidable theory or some theory the solver does not support. This paper proposes and evaluates several randomized solvers to address this issue. We compare the effectiveness of a symbolic solver (CVC3), a random solver, three hybrid solvers (i.e., mix of random and symbolic), and two heuristic search solvers. We evaluate the solvers on two benchmarks: one consisting of manually generated constraints and another generated with a concolic execution of 8 subjects. In addition to fully decidable constraints, the benchmarks include constraints with non-linear integer arithmetic, integer modulo and division, bitwise arithmetic, and floating-point arithmetic. As expected symbolic solving (in particular, CVC3) subsumes the other solvers for the concolic execution of subjects that only generate decidable constraints. For the remaining subjects the solvers are complementary

Efectos de la Iglesia Católica en el conocimiento de los pueblos autóctonos: Notas decoloniales

O presente artigo objetiva compreender alguns dos efeitos produzidos pela “entrada” Igreja Católica no saber dos povos das ex-colônias europeias, a partir de críticas a ela direcionadas por autoras e autores dentro do chamado “pensamento decolonial”. No recorte proposto, indaga-se: se o pensamento decolonial traz algo de novo em sua crítica, o que ele tem a dizer acerca dos efeitos da doutrinação da Igreja Católica sobre o saber dos povos que aqui estavam e de imigrantes forçados do transatlântico? É questionando a atuação no território da Igreja Católica que buscamos os efeitos da doutrinação sobre os corpos de saberes populares, autóctones.  Para realizar nosso intento, dispomos de revisão de narrativa, de modo qualitativo e não comparativo. Elegemos 5 autoras/es cujos olhares arque-viam a partir da perspectiva decolonial: Frantz Fanon, Lélia Gonzalez, Abdias Nascimento, Ramón Grosfoguel e María Lugones. A fim de apresentar algumas das principais críticas dessas/es autoras/es, separamos cada uma/m por blocos, nos limitando ao seu pensamento. Este procedimento foi adotado para facilitar a compreensão do pensamento de um determinado autor ou autora, nos detendo sobre ele/a. Por fim, apontamos algumas considerações gerais das hipóteses acerca dos efeitos da doutrinação católica nos saberes dos povos autóctones.This article aims to understand some of the effects produced by the “entrance” of the Catholic Church in the knowledge of the peoples of the former European colonies, based on criticisms directed at it by authors and authors within the so-called “decolonial thought”. In the proposed outline, the question is: if decolonial thinking brings something new in its critique, what does it have to say about the effects of the indoctrination of the Catholic Church on the knowledge of the peoples who were here and of forced immigrants from the transatlantic? It is by questioning the action in the territory of the Catholic Church that we seek the effects of indoctrination on the popular, autochthonous bodies of knowledge. To accomplish our intent, we have a narrative review, in a qualitative rather than a comparative way. We chose 5 authors whose gazes arched from the decolonial perspective: Frantz Fanon, Lélia Gonzalez, Abdias Nascimento, Ramón Grosfoguel and María Lugones. In order to present some of the main criticisms of these authors, we have separated each one by blocks, limiting ourselves to their thoughts. This procedure was adopted to facilitate the understanding of the thought of a particular author or author, focusing on him/her. Finally, we point out some general considerations of the hypotheses about the effects of Catholic indoctrination on the knowledge of indigenous peoples.Este artículo tiene como objetivo comprender algunos de los efectos producidos por la “entrada” de la Iglesia Católica en el conocimiento de los pueblos de las antiguas colonias europeas, a partir de las críticas que le dirigen autores y autores dentro del llamado “pensamiento descolonial”.

Es cuestionando la actividad en el territorio de la Iglesia Católica que buscamos los efectos del adoctrinamiento en los conocimientos populares, autóctonos.
