Abstract
Purpose
Sedentary living and respiratory/cardiovascular diseases affect respiratory and peripheral muscles. Muscle training can prevent, improve and reverse these changes. Their research question suggests that precise nutraceutical administration can enhance antioxidant capacity and muscle function. This sudy aims to evaluate the impacto of an innovative nutraceutical on blood biomarkers such as essential aminoacids, antioxidants, lipid profile, and REDOX status in healthy individuals, stable Chronic Obstructive Pulmonary Disease (COPD) patients, and mechanically ventilated patients.
Design/methodology/approach
The authors designed a nutraceutical to assess its effects on serum amino acids, lipid profile, vitamins, minerals and reduction-oxidation function. Conducted at a high-complexity care hospital, a study with a non-equivalent group design compared pre- and post-treatment administration.
Findings
The 29 participants were categorized into healthy individuals (n = 10), chronic obstructive pulmonary disease (COPD) patients (n = 10) and COPD patients receiving mechanical ventilation in an intensive care unit (ICU, n = 9) due to exacerbation. Analyzing serum values of selected markers and components before and after nutraceutical intake revealed significant differences. Oxygen radical absorption capacity units significantly increased (p = 0.0051) in healthy individuals. Isoleucine, valine, phosphorus, magnesium and calcium levels significantly increased in the healthy group.
Research limitations/implications
The small sample size and short duration limit the generalizability of results. The non-equivalent group design and lack of randomization may introduce bias, affecting reliability. Future research should involve larger, randomized controlled trials to confirm HIC1® benefits. Additionally, exploring long-term effects and optimal dosing in various populations, including different COPD stages and other chronic conditions, will provide more comprehensive insights. Despite these limitations, the study suggests promising implications for enhancing muscle function and antioxidant capacity through precise nutraceutical administration.
Practical implications
The administration of HIC1® demonstrates potential for improving antioxidant capacity and muscle function, particularly in sedentary individuals and those with respiratory or cardiovascular diseases. This study’s findings suggest that even short-term use of HIC1® can lead to significant increases in serum amino acids and other vital nutrients. Health practitioners should consider incorporating nutraceuticals like HIC1® into treatment plans for COPD patients and those requiring mechanical ventilation. Future research and clinical practice should explore optimal dosing and long-term benefits, potentially improving patient outcomes in chronic disease management.
Social implications
The use of nutraceuticals like HIC1® could have a significant impact on public health, especially for vulnerable populations such as the elderly and those with chronic illnesses. Improving muscle function and antioxidant capacity can reduce dependence on intensive care, decrease the economic burden on healthcare systems and enhance patients’ quality of life. Additionally, access to effective nutraceutical treatments could democratize healthcare, providing an affordable complementary option for preventing and managing muscle and respiratory diseases, promoting healthy and active aging in society.
Originality/value
This study is pioneering in evaluating the effects of a specifically designed nutraceutical, HIC1®, on both healthy individuals and those with chronic respiratory conditions. By focusing on precise nutraceutical administration, it addresses the gap in research on non-pharmaceutical interventions for enhancing muscle function and antioxidant capacity. The findings provide valuable insights into the potential of HIC1® to improve clinical outcomes in COPD patients and those undergoing intensive care, offering a novel, natural and potentially cost-effective approach to complement traditional treatments and support overall health and well-being.

Abstract
Purpose
The purpose of this paper is to contribute to thecomprehension of management education in the Global South, focusing on how contextual specificities, exemplified in the Colombian case, have driven curricular reforms. These reforms harmonize traditional practical training with a substantial emphasis on humanities education. to
Design/methodology/approach
Using a historical approach, this study conducts a heuristic and hermeneutic analysis of historical primary documents from archives, secondary sources and interviews.
Findings
The curricular reforms in Eafit’s Business Administration program responded to the need to diverge from a model borrowed from the United States. This departure leads to organic transformations that empower the inclusion of humanities for holistic professional manager education. This holistic approach was aimed to equip graduates to address organizational challenges and unique local issues, transcending conventional boundaries of education.
Research limitations/implications
This research serves as an initial exploration of a Global South case, laying the groundwork for future analyses of analogous cases. Comparative studies may eventually provide a more comprehensive understanding of management education beyond the Global North.
Originality/value
This work pioneers a relatively unexplored area of literature by investigating the history, unique aspects of business administration curricula and the role of curricular reforms within specific contexts. It is particularly pertinent in understanding the distinctive characteristics of business schools in the Global South. These institutions initially took inspiration from well-established American counterparts and literature reflecting Northern Global settings. However, they introduced innovations tailored to their local demands. This study spotlights the distinctive character of management education in Latin America, emphasizing a robust humanistic component.

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
Subject area
Management fundamentals, public management, social responsibility, strategy.
Study level/applicability
This case may be used in undergraduate courses on management fundamentals, public management, social responsibility, or strategy. Also, it is useful for strategy courses in MBA level and MA in development practice.
Case overview
In 1997, Corporación Picacho con Futuro (Picacho), a second-tier community organization created with the support of Fundación Social (FS) at Medellín's Comuna 6, stands at a crossroads. After promoting community development in the area for over ten years, FS announces that it will be withdrawing its financial support in the following year. As a result, self-sustainability mechanisms and strategies must be sought and formulated in preparation for FS' departure. The Corporation's accomplishments over its collaboration with FS were noteworthy: 16 grassroots organizations working together in one of Medellín's most violent districts proved the social fabric woven by Picacho. The young people who engaged in its projects had become examples of cohesion and civil resistance to armed groups' and drug-dealing networks' recruitment efforts. The Corporation's communication projects safeguarded these youths, providing them with a means to escape conflict. Would that all go down the drain without FS' support?
Expected learning outcomes
The intended focus of the case is to help students to understand: third sector organizations' complexity and structure; the notion of social value (how this value is created and measured); sustainability challenges facing social ventures, and, particularly, how to manage tensions between social and economic value creation in social organizations; support ecosystems for social ventures, and management strategies associated with base-of-the-pyramid businesses, introducing the concept of inclusive business.

Abstract
The Waorani are an Amazonian indigenous nationality with a population of 4,000. They inhabit three provinces of Ecuador: Pastaza, Napo and Orellana, and their ancestral lands contain a wealth of natural resources, which attracts the onslaught of the processes of extractivism. Significant social and economic asymmetries have also arisen in the decades since first contact. It is in this context that the Waorani Women's Association was created in 2005. Its main purpose is to end deforestation and illegal hunting of species in Waorani territory by promoting initiatives such as the cultivation of organic cocoa and handicrafts to improve the economy of families and to diminish the reliance on the preponderant economic system of use and abuse of non-renewable resources. This chapter analyzes how the spirituality of the Waorani nationality, manifested by the women who work in cocoa farms and chambira palm crafts, combine syncretism and ancestral knowledge in their daily work. It also analyzes the change of spiritual identity from the first contact with the Summer Language Institute missionaries, and subsequent evangelical, Catholic, Jehovah's Witnesses and the Church of Latter-day Saints missions to their lands.

Abstract
Purpose
This paper aims to identify future scenarios and convergent technologies regarding the plantain chain in the region of Quindío, Colombia. It proposes the definition of key variables, convergent technologies, future objectives, future scenarios and hypotheses based on stakeholders’ and experts’ opinions collected through questionnaires, surveys and workshops.
Design/methodology/approach
The present analysis seeks to identify and anticipate the future routes for the improvement of scientific, technological, innovative and skills management of the plantain agroindustrial chain in the region of Quindío, Colombia using the foresight-by-scenarios and, Delphi methodologies and finally validating the results with artificial intelligence code and natural language processing.
Findings
After the analysis of 100 initial variables, the results suggested the identification of five key variables defined by the stakeholders and matrix-based multiplication applied to a classification (MICMAC) analysis such as “weather,” “financing and economy,” “grouping and associativity,” “crop” and “territorial planning and raw material.” Moreover, the definition of four future objectives along with the matrix of alliances and conflicts, tactics, objectives and recommendations (MACTOR) analysis suggested scenarios according to the probability. The most possible, probable and desirable scenario, was the cooccurrence of the five proposed hypotheses. Furthermore, the Delphi analysis allowed us to define nine subgroups from 116 subtopics including: “plantain varieties,” “plantain agroindustry,” “waste use” and “crop,” among others.
Research limitations/implications
Due to the specificity of the analyzed agro-chain, the study only encompasses the plantain and banana sectors. However, the implications are related to the generation of projects in the selected technologies.
Practical implications
This paper includes implications for the development of prospective studies combining two or more different methodologies such as foresight-by-scenarios and Delphi method at the same time and further comparing the results with artificial intelligence analysis.
Social implications
The generation of public policies in the sector and input for governmental analysis and tools for decision-making with a well-grounded, systematic and rational point of view.
Originality/value
This work describes for the first time, the implementation of the Delphi method regarding an important agroindustry sector such as plantain and banana prospective study. Furthermore, it explains the alignment of two methodologies; foresight-by-scenarios and the Delphi method related to the sectorial approaches, and convergent technologies and innovations, respectively. Moreover, a complementary bibliometric analysis with global terms related to the plantain or banana agroindustry was also included. In a novel way, we also applied an artificial intelligence code using Python software to contrast the results previously obtained in the foresight-by-scenarios method.

Abstract
Purpose
This paper aims to evaluate the evolution of the organizational field in the Colombian coffee industry between 1960 and 2020 and explain how peripheral actors influenced institutional change.
Design/methodology/approach
The methods analyze historical processes from a hermeneutical and interpretative perspective. The authors used data collection techniques through interviews, archive data, publications and media reports, embracing an interdisciplinary and qualitative documentary approach. This approach helps the authors unravel the temporal dimensions of the historical discourse related to coffee and the involvement of various actors within organizational structures.
Findings
The authors found that, unlike the literature regarding the change in organizational fields, recently, within the coffee sector in Colombia, the institutional work of peripheral actors (small producers, local associative groups and coffee women, among others) is changing the field as follows: (1) women are changing traditional behaviors moving from hierarchical family structures and lack of gender awareness, to empowered, horizontal and sustained relationships, (2) indigenous people include rituals and other traditional practices in coffee production and (3) ex-guerrilla members are helping to strengthen the peace process implementation in Colombia through coffee production.
Research limitations/implications
The authors did not conduct statistical or computational analysis to simulate the emergence of new organizational forms. Instead, the authors attempted to elucidate narratives and discourses that reflect the tensions between central and peripheral actors from a historical perspective.
Practical implications
This study seeks to help leaders and managers overcome processes or organizational change in which peripheral actors are crucial. From that perspective, allocating resources and capabilities can become more effective.
Originality/value
This paper offers a new perspective of change within organizational fields from the roles of peripheral actors, which are fundamental in change processes within organizational fields, especially in the global south, where tensions between elites and vulnerable people are familiar.

Abstract
Purpose
This paper aims to provide an assessment of tourism promotion in tourist destinations and airports (TPTDs) and to organize and classify the literature on tourism promotion, with the aim of staging the importance of this topic and encouraging future research in the projection of tourism and marketing sectors.
Design/methodology/approach
The paper uses the Social Sciences Citation Index (SSCI) database to analyze the bibliometric in TPTDs topic from 2000 to 2021. Additionally, the paper also uses the visualization of similarities (VOS) viewer software to map graphically the bibliographic material. The graphical analysis uses bibliographic coupling, co-citation, citation and co-occurrence of keywords.
Findings
This study provides an amended new definition of tourism promotion, which is the efficient management of a destination’s resources and strategic plans by destination marketing organizations (DMOs) to adapt the tourism supply to market trends and will empower tourists to visit such destinations. Furthermore, results also show a new paradigm applied to TPTDs topic and classified in five first-order research streams. Digital and mobile marketing, infrastructure, branding, quality, accessibility and information factors about a specific destination which are mostly demanded by tourists are considered as an important means of promotion for the tourism industry.
Originality/value
The contribution of this study is important to identify new challenges and opportunities for researchers, DMOs, airport and airlines operators and stakeholders, as disentangling existing contradictions and applying new theoretical framework to make better future decisions by researchers and organizations to provide higher quality to new research in the context of the TPTDs.

Abstract
Purpose
This scientific article aims to evaluate the efficacy of the drug Doxorubicin for treating hepatocellular carcinoma (HCC) in Egypt. The study analyzes data from patients referred to a multi-disciplinary consultation at the National Cancer Institute, Cairo University. The study includes 40 intermediate-stage HCC patients who underwent treatment with either Doxorubicin-Lipiodol or Doxorubicin-loaded drug-eluting beads-trans-arterial chemoembolization (DEB-TACE).
Design/methodology/approach
Patients referred to a multi-disciplinary consultation at the National Cancer Institute, Cairo University with a possible diagnosis of HCC in the intermediate stage were eligible for the study.
Findings
The study finds that the plasma peak concentration of Doxorubicin is significantly higher in patients treated with Lipiodol compared to those treated with DEB-TACE. The median plasma peak concentration of patients treated with Lipiodol was significantly higher 424 (202.5–731) than the peak level of patients treated with beads 84.95 (26.6–156.5) with p-value = 0.036. However, there is no significant difference in other pharmacokinetic parameters between the two treatment groups. The research article also investigates the genetic polymorphisms in HCC patients treated with Doxorubicin-Lipiodol and Doxorubicin-loaded DEB-TACE. It identifies a significant association between the ABCB1 gene (C3435T) and the concentration of Doxorubicin in plasma. Patients with the CCand computed tomography (CT) genotypes of ABCB1 have higher concentrations of Doxorubicin compared to those with the TT genotype. Furthermore, the study examines the progression-free survival rates and tumour response in the two treatment groups. It demonstrates that DEB-TACE patients have a higher progression-free survival rate compared to cTACE patients. DEB-TACE also leads to better tumour regression.
Originality/value
The current study helps to increase the understanding of the genetic factors that may contribute to HCC susceptibility in the Egyptian population. However, it is essential to consider that genetic polymorphism is just one aspect of HCC risk, and other factors such as environment, lifestyle and viral infections also play crucial roles. Further research is needed to elucidate the complex interactions between genetic and environmental factors in HCC development among Egyptians.

Abstract
Purpose
This paper aims to present an evolutionary algorithm (EA) to accelerate the convergence for the radiative transfer equation (RTE) numerical solution using high-order and high-resolution schemes by the relaxation coefficients optimization.
Design methodology/approach
The objective function minimizes the residual value difference between iterations in each control volume until its difference is lower than the convergence criterion. The EA approach is evaluated in two configurations, a two-dimensional cavity with scattering media and absorbing media.
Findings
Experimental results show the capacity to obtain the numerical solution for both cases on all interpolation schemes tested by the EA approach. The EA approach reduces CPU time for the RTE numerical solution using SUPERBEE, SWEBY and MUSCL schemes until 97% and 135% in scattering and absorbing media cases, respectively. The relaxation coefficients optimized every two numerical solution iterations achieve a significant reduction of the CPU time compared to the deferred correction procedure with fixed relaxation coefficients.
Originality/value
The proposed EA approach for the RTE numerical solution effectively reduces the CPU time compared to the DC procedure with fixed relaxation coefficients.
