This work proposes the reuse of spent ground coffee waste (SCG) extracts as eco-friendly corrosion inhibitors for carbon steel in acid medium, and the correlation between their anticorrosive efficiency and chemical composition. The extraction method was optimized using a central composite design, and the chemical composition of the extracts was accessed using UV-Vis spectrometry, HPLC, and ICP-OES. EIS and Potentiodynamic Polarization (PP) tests evaluated the anticorrosive properties of the extracts. Total phenol content ranged from 93 mg L-1 to 219 mg L-1 Gallic Acid Equivalent. The highest concentration of phenolic compounds was observed for syringic acid (78.67 mg L-1), while the lowest concentration was verified for (-)-epigallocatechin-3-O-gallate (0.01 mg L-1). The Pearson correlation coefficient showed no correlation between the Rct and the total phenol content, although, positive correlations with the Rct was observed for caffeic acid, (+)-catechin, ferulic acid, and protocatechuic acid. EIS analysis revealed that all of the extracts could act as corrosion inhibitors. The best performance was verified for C3 extract (IE % = 94.83%). PP tests showed that this extract acted as a mixed inhibitor, with a predominant cathodic effect. Therefore, the valorization of the extracts as corrosion inhibitors was successfully achieved.

RESUMO Objetivo: Verificar o papel moderador das características dos gestores, como idade e tenure (tempo no setor, cargo, empresa), na relação entre a capacidade absortiva realizada (RACAP) e a capacidade arquitetural de marketing (CAM). Originalidade/valor: O presente estudo considera o elemento humano como fator que afeta as relações entre as capacidades da empresa. Contribui teoricamente ao auxiliar o entendimento do que pode impactar a formulação e implementação de estratégias de marketing, além de fortalecer teoricamente o papel do elemento humano. Como contribuição prática, demonstrou-se que não basta apenas buscar o conhecimento externo, mas também é necessário que ele seja transformado para então ser utilizado de maneira eficaz na elaboração e aplicação das estratégias de marketing. Design/metodologia/abordagem: Trata-se de pesquisa de caráter quantitativo, com corte temporal transversal. Este estudo testou empiricamente as hipóteses com base em uma amostra de 343 gestores de marketing de indústrias brasileiras de manufatura. Os dados foram coletados por meio de survey e tratados por meio de modelagem de equações estruturais no software AMOS. Resultados: As características dos gestores (idade e tenure) moderam a relação entre uma parte da RACAP (transformação do conhecimento) e a CAM (capacidade arquitetural de marketing). Gestores mais experientes devem ser valorizados, pois comprovou-se que, nesse setor, eles fazem a diferença na hora de transformar o conhecimento e utilizá-lo em suas estratégias.

ABSTRACT Purpose: This study aims to verify the moderating role of managers’ characteristics, age, and tenure (time in the sector, position, company), in the relation between the realized absorptive capacity (RACAP) and the architectural marketing capabilities (CAM). Originality/value: The present study considers the human element as a factor that affects the relations between the capacities of the company. It contributes theoretically to help understand what can impact the formulation and implementation of marketing strategies and theoretically strengthen the role of the human element. As a practical contribution, it has been shown that it is not enough to seek external knowledge, it is necessary that it is transformed and then used effectively in the design and implementation of marketing strategies. Design/method/approach: Quantitative research, with transverse temporal data collection. This study empirically tested the hypotheses based on a sample of 343 marketing managers from Brazilian manufacturing industries. Data were collected through a survey. Data were processed by means of modeling of structural equations in AMOS software. Findings: The characteristics of managers (age and tenure) moderate the relationship between a part of RACAP (knowledge transformation) and CAM (architectural marketing capability). More experienced managers should be valued because it has been proven that in this sector, they make a difference when it comes to transforming knowledge and using it in their strategies.
