This paper aims to develop a stable gel-type lubricant emulating commercial conditions. This encompassed rheological and tribological assessments, alongside field trials on the Medellín tram system.

The gel-type lubricant with graphite and aluminum powder is synthesized. Rheological tests, viscosity measurements and linear viscoelastic regime assessments are conducted. Subsequently, tribological analyses encompassing four-ball and twin disc methods are executed. Finally, real-world testing is performed on the Medellín tram system.

An achieved lubricant met the stipulated criteria, yielding innovative insights into the interaction of graphite and aluminum powder additives under varying tests.

Novel findings are unveiled regarding the interaction of graphite and aluminum powder additives in tribological, rheological and real-world trials. In addition, the wear behavior of polymers is observed, along with the potential utilization of such additives in tramway systems.

In this paper, we ask: how do individual factors affect individuals’ intentions of adopting fast payment systems (FPS)? We examine the role of financial literacy and beliefs about cash as individual-related variables that complement the technology acceptance model (TAM) in explaining the individuals’ intention to adopt financial innovations.

We surveyed consumers in 11 Latin American countries to measure relevant variables. By applying structural equation modeling, we extended the TAM. We demonstrated that financial literacy and beliefs about cash contribute to developing a fine-grained understanding of what stimulates individuals’ adoption of financial innovations like FPS.

Our results support the claim that individuals with higher levels of financial literacy exhibit a higher intention to adopt FPS through the mediation role of beliefs about cash, perceived usefulness, perceived ease of use and attitude.

To improve FPS’s acceptance probability, designers must add highly usable platforms. However, it could be more important to increase the perceived usefulness of FPS as the system competes directly with traditional payment methods such as cash. If individuals exhibit strong positive beliefs about cash, their attitudes and intentions of adopting FPS will decrease. In addition, policymakers and designers may modify beliefs about cash individuals exhibit by identifying and intervening in their determinants (e.g. financial literacy).

Besides technology-related factors, we demonstrate that beliefs about alternative technologies (e.g. cash) influence the intention to adopt financial innovations like FPS.

The aim is to analyze the armed conflict persistence in Colombia from 2008 to 2018 based on the financial viability hypothesis (rebellion occurs when war net revenue is nonnegative).

The methodology is quantitative. Firstly, a nonparametric Kaplan–Meier functions and survival risk functions are developed as initial approximation. Subsequently, a Probit model with panel data is implemented and the covariates are grouped into three dimensions: opportunity, grievance and institutional-political.

The viability hypothesis boosts the continuity of the armed conflict, which is enhanced and perpetuated by the viability and financial incentives from public revenues and natural resources, while the grievance, political fragmentation and institutional dimensions contribute to the opportunity structure in Collier that makes the conflict militarily and economically viable.

Lack of information for some states in Colombia prevents a much more holistic analysis.

Postulate what is required by the Colombian State to cut off the sources of financing of armed groups and thus, one of the determinants of the continuity of the conflict.

The political fragmentation contributes to rebellion, and that variables representing the dimensions of grievance and institutional presence contribute to the opportunity structure that makes the conflict in Colombia militarily and economically viable.

This research proposes as a novelty to incorporate the viability hypothesis with some factors related to the grievance that explain the persistence of the armed conflict as a consequence of decreasing recruitment costs for the insurgent groups, a situation that contributes to the opportunity structure and financial viability of the conflict.

This study developed a theoretical model to test the relationship between digital capability and Industry 4.0 (I4.0) and its effect on innovation performance in small and medium-sized enterprises (SMEs).

The proposed theoretical model was evaluated using partial least-squares structural equation modeling and fuzzy-set qualitative comparative analysis. The data were obtained from a sample of 536 SMEs in Chile.

The proposed model presented two dimensions of digital capability: management and information and communication technologies (ICTs). Management models composed of enterprise resource planning and customer relationship management systems are essential for optimizing organizational management. Meanwhile, ICTs facilitate the smooth flow of information within an organization, leading to improved efficiency in production processes. I4.0 is encouraged by exposing SMEs to base technologies such as data analytics. These results confirm that I4.0 influences innovation performance.

SME managers should encourage the development of digital capabilities to transition toward I4.0, as this can make SMEs more competitive and innovative in changing and dynamic scenarios.

I4.0 adoption and the development of digital capabilities can directly affect employment and national economic growth.

Most studies focus on the organizational factors affecting SMEs’ I4.0 adoption. They do not, however, address the role played by current digital capability in I4.0 technology adoption and its effect on firms’ innovation performance.

Este estudio desarrolló un modelo teórico para probar la relación entre la capacidad digital y la Industria 4.0 (I4.0) y su efecto en el desempeño de la innovación en pequeñas y medianas empresas (PYME).

El modelo teórico propuesto se evaluó mediante el uso de modelos de ecuaciones estructurales de mínimos cuadrados parciales y análisis comparativo cualitativo de conjuntos difusos. Los datos se obtuvieron de una muestra de 536 pymes de Chile.

El modelo propuesto presenta dos dimensiones de la capacidad digital: la gestión y las tecnologías de la información y la comunicación (TIC). Los modelos de gestión compuestos por sistemas de planificación de recursos empresariales y de gestión de relaciones con los clientes son esenciales para optimizar la gestión organizacional. Por su parte, las TIC facilitan el flujo fluido de información dentro de una organización, lo que conduce a una mejora de la eficiencia en los procesos de producción. La I4.0 se fomenta exponiendo a las PYME a tecnologías de base como el análisis de datos. Estos resultados confirman que la I4.0 influye en el rendimiento de la innovación.

La mayoría de los estudios se centran en los factores organizativos que afectan a la adopción de la I4.0 por parte de las pymes, pero no abordan el papel que desempeña la capacidad digital actual en la adopción de la tecnología I4.0 y su efecto en el desempeño innovador de las empresas.

Los gestores de las PYMES deben incentivar el desarrollo de capacidades digitales para realizar la transición hacia la I4.0, ya que esto puede hacer que las PYMES sean más competitivas e innovadoras en escenarios cambiantes y dinámicos.

La adopción de la I4.0 y el desarrollo de capacidades digitales pueden afectar directamente al empleo y al crecimiento económico nacional.

The objective of this chapter is to identify the key characteristics of Global Services businesses that will thrive and achieve success in the future. These factors are integrated into three main pillars, which we refer to as the Triple-Win. The first and most obvious pillar is technology as a tool. The second pillar is the design and sustainability of the business model, without which the previous factor would be merely a cost and not an investment. And last but not the least, there is the purpose which gives meaning to the proposal, focusing on the human being and their environment. The DIDPAGA business model sits at the intersection of these three elements.

Medellín, Colombia, experienced a remarkable social transformation in just two decades, leaving behind its troubled past of violence and insecurity. This study aims to identify the key actors and initiatives contributing to this transformation, considering cultural and social values shaping residents’ and visitors’ perceptions and determining the potential for the city’s brand. The research uses identity-based place branding theory and Delphi rounds to compare expert and promoter perspectives through surveys and tourist insights. The findings reveal recognising having a transformation in mind having offers guidelines for residents to propose tourism initiatives, aiding strategic city promotion and brand-building in collaboration with various organisations.
