The purpose of this study is to analyse the background and consequences of the Spanish job market on the employment conditions of Spanish women and on underlying attitudes on gender role in the working environment.

From the European Social Survey (2004, 2008, 2010, 2016), the authors draw a sample of 3,706 individuals aged from 25 to 64 years old living in Spain. The sample allows the authors to make estimations from several aggregation levels depending on gender (men and women) and generational cohort (baby boom and X generation).

Education improves the perception of women’s work among both men and women. The role of education is especially interesting for older people. Educational levels help women adapt to a changing context, promote female participation in the job market and protect them from unemployment situations. This study demonstrates that both gender and generational cohort moderate the impact of education on gender labour attitudes and working status.

Finally, this work is not exempt from limitations. For example, the use of cross sections does not allow the authors to obtain a richer set of causal relationships than the use of panel data would allow them. In addition, it would be interesting to replicate the study of gender labour attitudes among human resource managers and workers to have a broader view of what happens within companies.

The main contribution to the state of the art is to demonstrate that both gender and generational cohort moderate the impact of education on gender labour attitudes and working status. In addition, this study analyses whether gender labour attitudes change throughout the economic cycles, because population characteristics change (endowment effect) and/or because the same characteristics have different impacts (coefficient effect).

The purpose of this paper is the application of a tool to assist the multi-criteria decision-making process for selecting an asset for a company in the metallurgical industry which manufactures metal parts for diverse industries.

This investment, complex due to the commitment of resources it requires, has been made with the assistance of decision-making methodologies, specifically versions I and IV of the ELECTRE method.

This model of multi-criteria decision making has been chosen over other models because it offers the possibility of including technical and economic decisions so they can be analyzed simultaneously, therefore the decision is not based solely on financial aspects. Many companies base their decisions exclusively on financial returns, however in this case it is also appropriate to include the technical parameters, since the asset being replaced is the most important asset of the company.

Applying version I of the methodology, the optimal technical configuration of the asset will be analyzed based on the features requirements, all of which are among options available in the market. Once a subset of technically and economically viable alternatives has been defined, version IV will be applied and a ranking of the alternatives from the best to the worst will be obtained and, based on this ranking, the final decision will be made.

The purpose of this study was to prepare alginate and chitosan-based edible coatings incorporating Schinus terebinthifolia and Piper nigrum essential oils. The prepared films were applied on minimally processed pineapple to study the microbial inhibition of Gram + and Gram – bacteria and fungi and to evaluate the shelf life of the minimally processed fruit.

In this study alginate and chitosan-based edible coating were prepared and applied on minimally processed pineapple. The edible coatings were evaluated microscopically, by the power of reducing microbial contamination, by the shelf-life improvement.

This study demonstrates that the incorporation of the essential oils P. nigrum and S. terebinthifolia contributed to the inhibition of all the microorganisms studied and improved the shelf life of minimally processed pineapple. This is especially true for P. nigrum in the chitosan-based edible coating, where the shelf life was improved by 45 days.

Because of the pandemic, it was not possible to perform the sensory analyses of the antimicrobial alginate and chitosan-based edible coatings prepared.

From the results obtained, it is possible to state that the antimicrobial alginate and chitosan-based edible coatings incorporating S. terebinthifolia and P. nigrum essential oils can be used on minimally processed fruits and prolong their shelf life.

Due to the lifestyle of modern consumers, who demand speed and practicality and the need to consume fruits for health and quality of life, minimally processed fruits covered with edible coatings incorporating natural antimicrobial additives can provide a practical solution.

To the best of the authors’ knowledge, this is the first time that alginate and chitosan-based edible coatings that incorporate P. nigrum and S. terebinthifolia applied on minimally processed fruit, have been studied.
