This study aims to present the development and validation of a scale to measure the attitudes of Latin American business students toward sustainable management practices in the economic, social and environmental dimensions.

Using a nonprobabilistic sample, the appreciation for sustainable practices in students (ASP-S) scale was administered to a total of 653 undergraduate and graduate business students in Argentina, Colombia, Mexico and Peru. A range of psychometric validity (construct, convergent and discriminant) and reliability criteria were applied.

Construct, convergent and discriminant validity was obtained from the ASP-S scale across all samples. During the internal validation process, two factors were found: systemic consciousness (ten items) and sustainable business leadership (nine items), both of which obtained acceptable reliability indices. The resulting structure is equivalent in all four countries.

The instrument can be applied by educators and learning assurance areas to diagnose and measure the effectiveness of pedagogical strategies used in sustainability courses taught at Latin American business schools. As a result, it has applications for curriculum design. As a valid and reliable instrument set in the context of regional business praxis, it can promote an understanding of sustainable behaviors and practices in future Latin American leaders.

The purpose of this study is to use thermodynamic data to estimate the pressure exerted by the crystallization of iron oxyhydroxides following the equation proposed by Correns and Steinborn.

Standard free energy and molar volume data have been considered for goethite, lepidocrocite, magnetite and hematite, which are described in the literature as the most commonly found mineral phase rust constituents.

The studied mineral phases generate higher to lower crystallization pressure values in the following order: goethite > lepidocrocite > hematite > magnetite. The crystallization pressures calculated for these phases are in the 32-350 MPa range, which is higher than the tensile strength of concrete (of the order of 0.2-10 MPa) and thus leads to failure of the cover concrete.

The aim of this paper is to shed light on this issue by calculating the stresses generated by the crystallization of iron oxide from a supersaturated solution using thermodynamic data. A deliberately simplistic method was proposed, taking as reference the Correns–Steinborn model (Correns and Steinborn, 1939; Correns, 1949). The crystalline phases considered in this paper are those most commonly found in the literature as rust constituents, that is, goethite (α-FeOOH), lepidocrocite (γ-FeOOH), magnetite (Fe₃O₄) and hematite (α-Fe₂O₃). The FeO synthetic phase was also included as a reference.

The purpose of this paper is to study how repeat customers utilize their established overall restaurant brand image (ORBI), overall restaurant loyalty, satisfaction and behavioral intentions (revisit, recommend) to reengage with a casual-dining restaurant brand.

The study design consists of a mixed-methods, two-phase research approach that includes both qualitative and quantitative data. First, focus groups and in-depth interviews with adult customers reveal preliminary insights on restaurant dining patterns and familiarity with franchised casual dining restaurants. Second, an online self-administered survey tests the influence of ORBI on repeat customers’ overall restaurant loyalty, satisfaction and behavioral intentions.

For repeat customers, ORBI positively predicts loyalty and satisfaction. Loyalty and satisfaction mediate the relationship between ORBI and intentions to recommend, while loyalty alone mediates the relationship between ORBI and intentions to revisit a casual dining restaurant.

Managers looking to stimulate recommendation intentions can increase ORBI, loyalty or satisfaction among repeat customers; or choose some combination of these three predictors. To improve revisit intentions, managers should first increase loyalty, followed by ORBI. Importantly, management needs to tailor information given to repeat customers differently than other customers.

This paper provides a first conceptualization of how both loyalty and satisfaction jointly mediate the relationships between ORBI and two behavioral intentions (revisit, recommend). The results show that loyalty plays a significant role in these predictive relationships and is more important than satisfaction for enhancing intentions to revisit a restaurant.

This paper aims to review the history of Roldós y Compañía, one of the oldest advertising agencies in the world and the oldest currently operating. This research aims to highlight the importance of this agency and its founder, Rafael Roldós Viñolas – the first documented advertising agent in Spain to this day – in shaping the emerging Spanish advertising industry at the end of the 19th century.

The methodology used in this paper is based on a review of period and contemporary literature, as well as on newspaper sources and documents from the private archive of Roldós, S.A.

In its early years, the agency’s participation in two of the most significant events for the modernization of the city of Barcelona, the Universal Exhibition of 1888 and the International Exhibition of 1929; as well as the ideation and implementation of several urban projects with the aim of finding new formulas and advertising media are factors that make it one of the most important in the country. In 1929, the alliance Roldós-Tiroleses, S.A. de Publicidad, the first great merger of advertising agencies in Spain, which lasted three years, was led. The outbreak of the Civil War and the subsequent post-war period marked a few years of business irregularities and advertising silences that gave instability to its activity. During the last third of the 20th century, the agency was immersed in the generalized advertising euphoria around the world. With the arrival of North American agencies in Barcelona and the consequent business movements, Roldós, S.A. specializes in the processing of advertisements and media planning. The 21st century began with important changes in the media planning sector, and the agency was forced to restructure its services and organizational structure. In 2022, it celebrates 150 years of uninterrupted activity, recognized by the country’s business sector.

This research aims to internationalize the history of the Roldós y Compañía agency, so that it can be studied together with other names of Anglo-Saxon advertising pioneers who were contemporaries of Rafael Roldós.

Scientific research on the history of advertising agencies, especially in Spain, is scarce, so this paper aims to help fill this gap.

Medical devices are undergoing rapid changes because of the increasing affordability of advanced technologies like additive manufacturing (AM) and three-dimensional scanning. New avenues are available for providing solutions and comfort that were not previously conceivable. The purpose of this paper is to provide a comprehensive review of the research on developing prostheses using AM to understand the opportunities and challenges in the domain. Various studies on prosthesis development using AM are investigated to explore the scope of integration of AM in prostheses development.

A review of key publications from the past two decades was conducted. Integration of AM and prostheses development is reviewed from the technologies, materials and functionality point of view to identify challenges, opportunities and future scope.

AM in prostheses provides superior physical and cognitive ergonomics and reduced cost and delivery time. Patient-specific, lightweight solutions for complex designs improve comfort, functionality and clinical outcomes. Compared to existing procedures and methodologies, using AM technologies in prosthetics could benefit a large population.

This paper helps investigate the impact of AM and related technology in the field of prosthetics and can also be viewed as a collection of relevant medical research and findings.
