Cosmological Tests Based on General Relativity for Gravity
Get PDFIn the realm of cosmology, understanding the nature of gravity is crucial for unraveling the mysteries of the universe. The current cosmological models are built based on general relativity. The solutions of the specific equations, Friedmann-Lemaître-Robertson-Walker, allow to model the evolution of the universe starting from the Big Bang. Some of the parameters of the universe have been established by observations. Based on these, and other observational data, the models can be tested. Predictions include the initial abundance of chemical elements formed in a period of nucleosynthesis during the Big Bang period, the subsequent structure of the universe, cosmic background radiation, and so on

SBU 40 anos : uma visão por meio de seus gestores (1983-2023)
Get PDFThis e-book, “SBU 40 YEARS: A VIEW THROUGH ITS MANAGERS (1983-2023),” aims to provide an overview of the UNICAMP Library System over four decades, through the accounts of its managers. Through their experiences, we learn about the evolution of the SBU, from its creation to the present day, in a context marked by profound changes in society, in the university, and especially in the field of information and technology. Each chapter, written by a manager, portrays a unique period in the history of the SBU, revealing challenges, strategies, advances, and the impacts of their actions. The narratives provide a rich mosaic of perspectives on university library management and, at the same time, on the importance of teamwork, the pursuit of innovation, and a passion for the mission of contributing to the development of the academic community

El análisis permitió conocer la interacción entre el cerebro humano y las funciones del neocórtex, cerebro límbico
y primitivo. Se desarrolló un estudio de tipo cuantitativo y cualitativo. Los análisis estadísticos, con una alta
confiabilidad (α = 0,922) y correlaciones significativas (τb de Kendall = 0,818, p < 0,001; ρ de Spearman = 0,889,
p < 0,001), muestran una fuerte asociación entre neuromarketing y comportamiento del consumidor. Los resultados
indican que las técnicas de neuromarketing impactan significativamente en la motivación emocional y las
decisiones de compra, resaltando la importancia del entorno de la tienda y factores ambientales en la percepción

Presentaciones sobre accesibilidad web: el aporte de mujeres en congresos de informática realizados en Argentina entre 2020 y 2022
No full textNumerous approaches investigate the reduction of gaps and inequities in the knowledge society, where ICTs, as services and products are present. These approaches include the Sustainable Development Goals and Web Accessibility. Both issues are global and on the international agenda. The article investigates the participation of women from university environments through their productions disseminated in congresses originated in Argentina. The methodology applied is descriptive based on the method of Evidence-Based Software Engineering. The exhibition was made up of the presentations disseminated in five congresses originated in Argentina and carried out in the period 2020-2022. Systematized empirical evidence shows the explicit and implicit social responsibility that emanates from university environments. In addition, it is remarkable the participation of women in the design, development and study around a topic of global connotation such as Web Accessibility. In this sense, the results contributes to the approach of the 4th, 5th and 10th Sustainable Development Goals
Comunicación científica: uso de las redes sociales en las revistas científicas
No full textThe emergence of web 2.0 and social networks has modified the forms of scientific communication through scientific journals. Their use generates benefits and enables rapprochement, exchange and debate with specialized and non-specialized audiences. The present research aims to conduct a literature review of the theoretical-conceptual aspects related to the use of social networks by scientific journals. It is a descriptive study with a bibliographic and documentary analysis. As a main result, it was possible to verify different aspects such as: benefits of the use of these channels, indicators for analytics, social networks most used to disseminate their articles and communicate with authors and readers, among others. It is concluded that scientific journals that have implemented communication strategies, including the use of general, academic and professional social networks, show satisfactory results
Identifying the Effective Components on Nurses' Knowledge Sharing Behavior with Mixed Method Research
Get PDFBackground. Knowledge-sharing is a process in which people mutually exchange tacit and objective knowledge and create new knowledge. This study aimed to identify the main themes and organize the components of nurses' knowledge sharing.
Methods. A mixed research method was adopted to conduct the present study. To this end, a qualitative method with a thematic analysis approach was first implemented to investigate the statistical population. The required data were collected by reviewing the published national and international articles using the keyword "knowledge sharing" in search engines. In total, 387 scientific research articles were retrieved from searching the literature. Then, the inclusion criteria were used to filter the information and reduce the number of articles to 48 containing the related codes specific to the themes. The quantitative part was an analytical survey. The statistical population included the nurses of Kermanshah University of Medical Sciences. The structural equation modeling methodology was adopted to determine a sample size of 284 individuals.
Results. In the qualitative part, there were 27 main themes, 11 sub-core themes, and nine knowledge-sharing organizing themes, including attitude, mental norms, rewards, costs, perceived behavioral control, mutual benefits, knowledge-sharing tools, and perception of gaining reputation. The components of knowledge-sharing intention were identified in the quantitative part based on the nurses' points of view, and gaining reputation, mutual benefits, and mental norms were found the most important components in order of priority.
Conclusion. Based on the findings of this study, the components of attitude, perceived behavioral control, reward, mutual benefits, reputation and subjective norms are effective in the knowledge sharing behavior pattern of nurses and can cause the actual behavior of the individual
La ansiedad informacional en estudiantes universitarios : explorando los desafíos de la era digital
Get PDFHe prevalence of information anxiety in the context of the digital society is not limited to a specific sector but affects the population as a whole (Bawden and Robinson, 2009). However, it is imperative to direct our attention to a particularly susceptible group to experience this phenomenon: university students. This assertion is based on previous research indicating that this demographic group may be especially vulnerable to experiencing this type of anxiety (Eklof, 2013 and Costa, 2022). This vulnerability is rooted in the academic demands that university students face, which are compounded by family and social responsibilities that also fall upon them. This convergence of factors unfolds in an increasingly complex information environment. In this context, university students are subjected to significant pressure that can considerably elevate anxiety levels. As a result of this interaction, a diversified impact is observed, ranging from academic performance to the physical, emotional, and psychological well-being of students
Relationship of the disruption indicator with other bibliometric indicators
Get PDFAn indicator to measure disruption has recently been proposed (Funk & Owen-Smith, 2017; Wu, Wang, & Evans, 2019) which has given rise to a large number of variants (Bornmann et al., 2020). In this work we are going to focus on the original indicator DI and the one that seems to have a better performance DI5 (Bornmann and Tekles, 2021; Bittmann et al., 2021) carrying out a large-scale study comparing the scores assigned to each paper. with other bibliometric indicators. The result is that the papers to which the bibliometric indicators assign more value do not obtain better scores. Reviews and short surveys have higher scores than articles and conference papers. Excellent papers have worse scores than non-excellent ones. Works with international collaboration obtain worse values than those without it. Works published in Q1 journals have worse scores than those published in journals of other quartiles. And there is also a small negative correlation with the normalized impact and with the technological impact
