Abstract
Purpose
In order to understand interactions aw vs equilibrium moisture content (EMC) in fortified coconut powder, moisture sorption isotherms were constructed under different storage conditions in order to predict the changes in their physical, chemical and microbiological properties that occur during storage and processing, which are unique to each food.
Design/methodology/approach
For which the moisture sorption isotherms were determined at three different temperatures (15, 25 and 35 °C), in a range of water activity from 0.1 to 0.90. Nine models, namely, the GAB, BET, Oswin, Smith, Halsey, Henderson, Chung and Pfost, Peleg and Caurie equations, were fitted to the sorption data. Various statistical tests were adopted as criteria to evaluate the fit performance of the models.
Findings
Of the models tested, the Peleg model gave the best fit to experimental data (R2 = 0.997; RMSE = 0.276), across the full range of water activities and at different temperatures. Humidity of the monolayer (mo) was found between 2.54 and 2.34%, a fundamental parameter to define the storage and control conditions, given that it is considered the value at which the product is more stable. The net sorption isosteric heat (Qst) increased to maximum and then diminished with increased moisture content (Xw); maximum values were obtained in the Xw interval between 0.48 and 2.87% (db), being between 35.72 and 99.26 kJ/mol, where the maximum value indicates coverage of the strongest bond sites and higher adsorbate-adsorbent interaction.
Originality/value
These results provide reliable experimental data on water absorption isotherms of the CP + FAC important to determine optimal processing, storing and packaging conditions.

Abstract
This chapter reports on the difficulties and challenges faced by a woman in Mexico to generate an enterprise whose objective is education. This is achieved by taking up the story of Sharon Zaga and Mili Cohen, two Jewish women who set themselves the goal of founding a museum that would speak of the relevance of historical memory, but also of the importance of tolerance. The emergence of COVID-19 presented them with a new challenge: the museum had to remain closed for more than a year. We will explore the strategies that allowed them to keep their organization afloat, a circumstance that can be taken up by more Latin American women who intend to undertake also on their own.

Abstract
Purpose
Seeking online bilingual scientific information is a key aspect of bilingual scientific Web literacy – abilities to engage critically with science on the Web using two languages. This study aims to determine whether factors such as age, education major, gender and type of school attended at secondary level (monolingual, bilingual, trilingual) influence undergraduates’ ability to search online Spanish-English bilingual scientific information.
Design/methodology/approach
The participants in this study were 60 students (43 females and 17 males, 18–25 years old) enrolled in a university bilingual science course at a high-ranked Colombian university. They were asked to complete two tasks in which they had to seek online scientific information in Spanish and in English and post their responses on the Web application, Padlet® (padlet.com).
Findings
Results indicate that students’ gender and age influence their academic performance in both tasks and level of originality in using information obtained via the Web, respectively. Moreover, the “scientific journal” was the top source of online information from which participants sought most information to complete both tasks.
Originality/value
People are becoming increasingly accustomed to seeking and sharing online scientific information to support points of view and make decisions. However, it is not known which factors influence students’ ability to seek online first language-English bilingual scientific information in countries where English is the second or foreign language.

Abstract
Purpose
The objectives of this study are twofold: identify the main challenges in performing training on Industry 4.0 concepts to managers operating in the manufacturing sector who are not familiar with them but aspire for an Industry 4.0 broad view and validate training practices that can be adopted to reduce managerial knowledge differences.
Design/methodology/approach
A Delphi method was carried out in two rounds to identify the Industry 4.0 training challenges and a Fuzzy Delphi method was applied in one round to validate the training practices. Both methods used the same set of participants composed of experts in training for Industry 4.0. Results were discussed considering literature statements.
Findings
In total, 11 challenges in Industry 4.0 training were identified and grouped into: challenges associated with the necessary knowledge, challenges of breaking paradigm, challenges associated with training characteristics and challenges associated with expected results. In total, 11 training practices were directly validated, including actions to be adopted before, during, and after the training process.
Originality/value
The findings are relevant for professionals, academics, or consultants as the findings enable better training planning and execution. No similar papers were found in scientific databases, reinforcing this present study's originality and contribution.

Abstract
Purpose
Although the concept of transformative gamification is mentioned in previous research, no research has provided a theoretically based explanation of how gamification can lead to transformative change. This paper aims to provide the explanation for the first time by combining storytelling elements with cognitive behavioural therapy logic and incorporating these into a framework to show the process of transformative behaviour change through gamification. The proposed framework not only furthers the theoretical understanding of transformative gamification services but also provides practical insight into design and implication of such services.
Design/methodology/approach
This paper is based on critical analysis and synthesis of literature from different fields of research such as transformative service research (TSR), gamification, game studies, social marketing, storytelling and journalism. Ergo, several propositions based on the extensive literature review are proposed and aggregated in a conceptual framework.
Findings
This paper argues that apart from game mechanics that are often considered as an inseparable aspect of gamification services, immersive storytelling and a mechanism to encourage reflection are the pivotal components of transformative gamification services. In addition, this paper suggests that although reflection and immersive storytelling are often considered as opposite sides of the spectrum, they can have a synergistic effect once they work in tandem in gamification services.
Originality/value
This paper proposes a novel framework and an operational definition for transformative gamification services. It contributes to TSR, gamification and health promotion research through differentiating this concept from similar concepts, such as mHealth, propelling gamification to a more meaningful and user-centric version and providing service researchers with a practical guide to make use of gamification as a tool to serve TSR.
