Abstract
Purpose
This study aims to report the development of an open-source syringe extrusion head for shear-thinning materials. The target is to adapt open-source 3D printers to be helpful in research lines that use gels, hydrogels, pastes, inks, and bio-inks.
Design/methodology/approach
This hardware was designed to be compatible with a Graber i3-based 3D printer; nevertheless, it can be easily adapted to other open-source 3D printers.
Findings
The extrusion head successfully deposits the material during the 3D printing process. It was validated fabricating geometries that include scaffold structures, which are a possible application of bioprinting for tissue engineering. As reported, the extruded filaments allowed the porous samples' structuration.
Practical implications
This system expands the applications of open-source 3D printers used at the laboratory scale. It enables low-cost access to research areas such as tissue engineering and biofabrication, energy storage devices and food 3D printing.
Originality/value
The open-source hardware here reported is of simple fabrication, assembly and installation. It uses a Cardan coupling and a three guides system to transfer the stepper motor motion. This approach allows continuous movement transfer to the syringe piston, producing an adequate deposition or retraction. Thus, the effect of misalignments is avoided, considering that these latter can cause skipping steps in the motor, directly affecting the deposition.

Abstract
Taking as reference a sample of around a hundred biographical materials on entrepreneurs in Mexico and Colombia, the purpose of this chapter is dual. Both to show the relevance and varied modalities that the biographical approach has enjoyed in business history research since the 1990s, and to display the intrinsic potential this modality of scholarship entails for entrepreneurship endeavors. In particular, it discusses the prospects to incorporate this body of empirical works into the large Latin American audience attending undergraduate, graduate and executive education programs in business, economic history and related fields. The chapter is organized into three sections. The first two are devoted to illustrate relevant patterns in the entrepreneurial trajectory of individuals and entrepreneurial families studied in each of the two countries under consideration. The last section identifies some conceptual issues that may impact current debates on Latin American business development as exemplified in recent business and economic history journal venues and scholarly conferences.

Abstract
“When James Boswell returned from a tour of Corsica in 1765 he wrote: ‘It is indeed amazing that an island so considerable, and in which such noble things have been doing, should be so imperfectly known.’ The same might be said today of Puerto Rico.” Thus began Millard Hansen and Henry Wells in the foreword to their 1953 look at Puerto Rico's democratic development. Four decades later, the same could again be said about the island.

Abstract
Purpose
The purpose of this paper is to empirically evaluate the effect of heterogeneity in inter‐organizational collaboration networks on international high‐quality scientific performance of the most reputed business management schools in Latin America according to AméricaEconomía ranking.
Design/methodology/approach
Starting from the debate between advantages and disadvantages of heterogeneity in scientific performance framed in the debate between organizational population ecology and organizational institutionalism theories, this research explores the relationship between heterogeneity, reputation and the most important features for doing research. Using a binomial negative regression, the paper evaluates the partial effect of those variables in the count of scientific production.
Findings
There is an isomorphical tendency from the most reputed schools to establish heterogeneous networks, showing empirical evidence to normative proposals from Latin America, specially formulated in the light of Sabato triangle. Also there are differentiations between schools in aspects like human capital, double‐degree agreements, and schools’ trajectories.
Research limitations/implications
It is necessary to choose a wider sample of schools and to include Latin American journals. The study of diversity (between researchers) and its relationship with heterogeneity (between organizations) is also needed.
Practical implications
The research shows that elite business management schools in Latin America that present better performance also present high levels of heterogeneity in their inter‐organizational collaboration. Therefore, the promotion of heterogeneity could enhance scientific performance and improve techno‐economical networks.
Social implications
This research hopes to aim the research policy design to be able to steer and promote heterogeneity that could improve the relationship between producers and users of knowledge.
Originality/value
The relationships between reputation, heterogeneity, and scientific performance in administration in Latin America had not been addressed empirically. The worth of this research is the empirical confirmation to the advantages of heterogeneity, rather than intellectual capital features of schools, in research collaboration that contribute to the debate about heterogeneity and performance.
Propósito
Evaluar empíricamente el efecto de la heterogeneidad de las redes de colaboración interorganizacionales en el desempeño científico de alta calidad internacional en las escuelas de administración y negocios más reputadas en América Latina de acuerdo con el escalafón de AméricaEconomía.
Metodología
Con base en el debate que concierne a las ventajas y desventajas de la heterogeneidad en el desempeño científico enmarcado dentro del debate entre las teorías de la ecología de poblaciones y el institucionalismo organizacional, esta investigación explora la relación entre la heterogeneidad, la reputación y las características más importantes que pertenecen a la investigación. Usando la regresión binomial negativa, el artículo evalúa los efectos parciales de las variables en el conteo de la producción científica.
Resultados
Hay una tendencia isomórfica de las escuelas más reputadas por establecer redes heterogéneas, mostrando evidencia empírica para las propuestas normativas de América Latina, especialmente formuladas a la luz del triángulo de Sabato. También hay diferencias entre las escuelas en términos del capital humano, los convenios de doble titulación, y la trayectoria de las escuelas.
Limitaciones de la investigación
Es necesario escoger una muestra más amplia de escuela e incluir a las revistas de América Latina. El estudio de la diversidad (entre investigadores) y su relación con la heterogeneidad (entre organizaciones) también es requerida.
Implicaciones
La investigación muestra que las escuelas de administración en América Latina que presentan mejor desempeño también presentan altos niveles de heterogeneidad en su colaboración interorganizacional. Por lo tanto, la promoción de la heterogeneidad podría añadir al desempeño científico y mejorar las redes tecno‐económicas.
Implicaciones sociales
Esta investigación espera impulsar el diseño de políticas de investigación y a su vez promover la heterogeneidad que pueda mejorar la relación entre los productores y usuarios de conocimiento.
Originalidad/valor
La relación entre reputación, heterogeneidad y desempeño científico en administración en América Latina no ha sido abordada empíricamente. El valor de esta investigación es la confirmación empírica de las ventajas de la heterogeneidad, en vez de otras características de las escuelas, en la colaboración científica que contribuye al debate sobre heterogeneidad y desempeño.

Abstract
Purpose
The objective of this study is to determine the efficiency of tourist accommodation companies located in the main tourist area of southern Europe as one of the three elements of the local sustainable development triangle.
Design/methodology/approach
The analysis, carried out using the data envelopment analysis (DEA) methodology on 130 companies, has obtained that from the CCR perspective (results-oriented method when companies present constant returns on the input variables).
Findings
The companies involved are quite inefficient, while which from the BCC perspective (where the input and output variables used in the company respond to a variable and not constant scale) are quite efficient. The efficiency of these companies in the seven provinces of Andalusia has also been analysed to determine if there are patterns that differentiate them and thus be able to propose strategies that improve the sustainability of these territories. The conclusions of the study indicate the need to improve the operational efficiency of rural accommodation companies.
Originality/value
The analysis of efficiency in the hotel sector and even more so in the rural tourism sector is relatively scarce in the literature, especially in Spain. More specifically, Rubio and Román (2006) have demonstrated the existence of scale inefficiencies in hotels, but no evidence has been found in previous studies that this behaviour carries over to accommodation establishments located in the destinations under study.

Abstract
Purpose
ISO 9001:2015 edition, by adopting modern management and quality approaches, can foster the application of continuous improvement (CI) methodologies. The purpose of this paper is to assess the level of utilization of Kaizen and other CI methodologies within Portuguese ISO 9001 certified organizations, namely, amid organizations that have already implemented ISO 9001:2015.
Design/methodology/approach
After the literature review, a quantitative research, supported on an online survey, was adopted. The survey yielded 309 valid responses (response rate 18 percent) encompassing 71 organizations already certified against ISO 9001:2015 and the remaining 238 against ISO 9001:2008. The results of the statistical analysis performed were reviewed with a focus group of five quality and organizational excellence managers.
Findings
The results show a mildly use of Kaizen, Lean and Six Sigma (SS) by Portuguese ISO 9001 certified organizations, which is increase when compared to previous studies. The sample of organizations that are already certified by ISO 9001:2015 have mean and median levels of customer improvement methodologies adoption (Lean, Kaizen, SS) higher than those that are still certified against ISO 9001:2008. However, the Kruskal-Wallis test showed that these differences are not statistically significant. Concerning the adoption of these methodologies by activity sector, the sample median values seem to suggest that Lean and SS are more commonly adopted in the industry than in the services, but according to the Kruskal-Wallis test these differences are not statistically significant. Checklists, plan-do-check-act cycle and process diagrams, followed by DMAIC, are the quality tools that are most frequently adopted. A high workload due to the transition process for ISO 9001:2015 and the lack of qualified people were suggested as possible explanations for these results by the Expert Focus Group.
Research limitations/implications
The study is restricted to ISO 9001 certified organizations in Portugal and due to the short time since ISO 9001:2015 implementation it should be considered as having an explanatory nature and subject to future confirmation.
Originality/value
This study on the application of CI methodologies between ISO 9001:2015 and ISO 9001:2008 certified organizations contributes to the Kaizen and CI body of knowledge and provides inputs to the organizations and professionals that aim to successfully apply it.

Abstract
Purpose
Our study focuses on providing empirical evidence regarding the optimization of podcasting in asynchronous learning. This action research aimed to innovate the delivery of asynchronous classes using differentiated podcasts.
Design/methodology/approach
We utilized action research as the research design for the study. Participating in action research entails developing practical knowledge to improve educational practices through specific methods and critical perspectives (Sáez Bondía and Cortés Gracia, 2022). According to Burns (2007), action research involves deliberate interventions usually prompted by identified issues, mysteries or inquiries that individuals in the social setting seek to improve or change. Implementing changes to enhance individuals' actions and understanding within their context is the focus of action research (Kemmis, 2010). The study’s approach is ideal for examining new practices and gaining enhanced theoretical insights (Altrichter et al., 2002). Engaging in action research helps enhance understanding and empowers us to impact and enhance practices through continuous reflection, exploration and action. Through this iterative process, we can continuously enhance our comprehension and make substantial strides toward fostering positive transformation.
Findings
The study findings showed an apparent rise in student regulation and engagement and remarkable enhancements in learning outcomes, as demonstrated by differences in pre-test and final exam scores. These results highlight the actual effect of specialized podcasts on self-paced inducing students' self-efficacy in learning. Our research provides valuable insights on effectively incorporating podcasts into education, offering innovations and improvement of practice among educators and institutions adapting to the ever-changing landscape of the educational environment while catering to the diverse needs of the learners. This research is pioneering research catering to the various learning styles of asynchronous learning environments.
Research limitations/implications
Although our current sample offered valuable insights, upcoming studies could gain from more extensive and more diverse participant groups to strengthen the reliability of our results and guarantee broader applicability across various demographics and contexts. Moreover, the length of our intervention may have been relatively brief, which could have limited our ability to evaluate the long-term impact of customized podcasts on learning results. Continued investigation into the long-term effects of these interventions could provide valuable insights into their effectiveness over time and help shape the creation of more lasting educational approaches.
Practical implications
Innovation in asynchronous learning differentiated teaching attuned to the diverse learning styles of the students.
Social implications
The study promotes equitable education, which eventually promotes learning outcomes of the students.
Originality/value
We created differentiated podcasts tailored to the learning styles of the students. This research is pioneering research catering to the various learning styles of asynchronous learning environments.

Abstract
Departing from a so-called “modern civil service” as an ideal type, this chapter evaluates the status of public personnel management in Latin America. Such an ideal model is considered a mix between the organizational principles of the traditional civil service and those of the new public management perspective. First, the chapter presents the different phases that public management practices have undergone in some developed countries. Secondly, following several studies and data provided by the IADB, the level of development of several civil service systems in Latin America is analyzed and several of their construction–destruction–reconstruction patterns are presented. Lastly, the cases that most approach a modern civil service are discussed and some recommendations offered to reformers in this region.

Abstract
Purpose
Knowledge management has historically been approached in private firms as a key factor for business management. However, this is not the case for government institutions. The existing literature on the transfer of knowledge appears as a topic little addressed in government and even to a lesser degree within the police forces. This study aims to evaluate the relationship between motivation, knowledge absorption, knowledge transfer and innovative behavior in a public organization such as the Puerto Rico Police.
Design/methodology/approach
This quantitative research using the survey technique had the participation of 300 police officers from the 13 police regions of Puerto Rico and the research model was analyzed through partial least squares structural equation modeling.
Findings
The results contribute to the growth of the currently limited literature at identifies how motivation, knowledge absorption, knowledge transfer and institutional support influence innovative behavior.
Originality/value
The study discusses a series of implications on less explore the issue in how the transfer of knowledge becomes a key force to produce change and the success of all reforms. Various implications for the success of public administration in bringing a change from a bureaucratic culture to an advanced one are also discussed.

Abstract
Because I want the next generation of women to be set free from the birdcage of racial, gender and class stereotypes, a place from which my mother, grandmothers and great grandmothers never had the chance to escape, it is a personal and political choice to rupture the experiences of racial prejudice that bind us into phobic races within various shades of hatred. I am both digging a new place to find “truth” and criticizing an essential part of who I am or what I was taught to believe about our black and indigenous heritage. An epiphanic moment combines past, present and future moments into an act of doing and becoming. In honoring the first “queen” in my family, I wrote the following non-fiction children's story about my great grandmother Bernarda in three languages. Although I have never seen a picture of Bernarda, I feel her Chibcha blood burning inside of me and within every awkward phrase that I piece together as I fumble through grammatical structures, reviving memories into performative language. I wrote the first draft in English and later translated it into French and Spanish.
