Purpose: This paper analyzes the publications on the “authentic leadership” construct, based on systematic literature review and bibliometric analysis techniques, and aims to identify and analyze data regarding the chronology of publications, the identification of the most prolific journals and authors, research approaches, and the existence of authentic leadership measurement/assessment tools and its applications, besides analyzing the construction of these tools. Originality/value: Of the 431 articles analyzed, those dealing with reviews of literature do not present bibliometric data associated with the analysis of the construct measurement instruments. Design/methodology/approach: A literature review was performed systematically, using the query “authentic leadership” on the Academic Search Premier (Ebsco), Scopus, and Web of Science databases, with no starting date delimitation, with the deadline of December 2018, which resulted in the identification of 1390 articles. After eliminating duplicates and three filters, 431 documents remained for analysis. Findings: Three specific construct measurement/assessment tools were identified: the Authentic Leadership Questionnaire (ALQ), the Authentic Leadership Inventory (ALI), and the Authentic Leadership Integrated Questionnaire (AL-IQ). There is a predominance of quantitative studies from 2008, with a wide application of ALQ. Instruments of quantitative measurement of authentic leadership did not emerge, only tools that evidence the presence of authenticity of leaders.

O objetivo do presente artigo é classificar sistemas de medição de desempenho (SMD) de acordo com as abordagens utilizadas. Foram revisadas 140 abordagens sobre o tema, no período de 1980 a 2007. Após a revisão, as abordagens foram classificadas baseando-se em cinco critérios: quanto à abrangência; quanto ao tipo de abordagem; quanto ao foco; quanto ao nível de medição; quanto ao grau de complexidade; bem como a algumas questões complementares. Verifica-se que o ambiente em que os SMD estão mais difundidos é o corporativo, no entanto, atualmente, várias abordagens vêm tratando da cadeia de suprimentos, serviços e indivíduo. A maioria das abordagens analisadas foi do tipo prática, com foco não financeiro e nos mais diversos níveis de medição e grau de complexidade. As contribuições deste trabalho concentram-se na geração de um melhor e sistematizado conhecimento sobre o tema de sistemas de medição de desempenho, bem como na identificação das tendências futuras dentro deste tema.

Purpose: The purpose of this paper is to verify if, in the dairy business ecosystem (dairy farmers, dairy cooperatives, government, research agencies, consultants and financial institutions) perspective, the dairy production barriers presented by Bonamigo et al. (2016b) can be mitigated through the dairy production key factors indicated in the literature. Design/methodology/approach: To achieve the proposed goal of this study, the methodology used for the study comprises three stages: exploratory search in the literature to identify barriers and drivers of dairy production, data collection and statistical model. For the first stage, the authors conducted exploratory research in the literature, to better understand the dairy production ecosystem and to find arguments that characterize the barriers and drivers of this activity. In the second stage, a structured questionnaire with 13 closed-ended questions in a single block, with ordinal responses, following the suggestion of Likert (1932), was developed and applied to the dairy production ecosystem players of Santa Catarina, Brazil. A total of 305 responses suitable for analysis based, that were analyzed through an exploratory factorial analysis and modeling of structural equations via partial least squares, resulting in the Statistical model. Findings: Based on the analyses results, the authors verified that there is an inverse association between the characteristics of the barriers and the dairy production key factors. In this sense, the authors can confirm that the increase of the loads in the dairy production key factors, reduce loads of the milk production barriers. Based on the results of this test, new theoretical and practical insights can be identified to develop new studies with the aim of boosting the dairy sector development as well as providing support in the decision making of the dairy system players. Research limitations/implications: This study may not have enabled a complete coverage of all existing peer-reviewed articles in the field of dairy production. It seems reasonable to assume that the review process covered a significant proportion of studies available. Originality/value: It is the first study that compares identifies barriers and key factors of dairy production in Santa Catarina using as an analytical lens the business ecosystem.

O presente artigo propõe um modelo multidimensional para medir a qualidade de websites comerciais com uso da Teoria da Resposta ao Item (TRI). A qualidade de um website engloba características técnicas (usabilidade/navegabilidade, apresentação da informação e interatividade) e não técnicas (design, estética, apelo visual, confiabilidade, hedonismo, imagem), configurando-se, teoricamente, como contexto multidimensional. As suposições iniciais das dimensões e elaboração dos itens foram baseadas em análise bibliográfica sobre o tema qualidade em websites de e-commerce. Um conjunto de 75 itens foi elaborado e uma amostra de 441 websites de e-commerce dos mais variados setores foi a ele submetido. O tratamento e análise dos dados foram feitos utilizando-se a TRI. Nessa etapa, foram discutidas questões referentes à dimensionalidade e à escolha do modelo mais adequado. Por fim, um modelo multidimensional com quatro dimensões foi ajustado contemplando as dimensões navegabilidade ou condução/orientação do usuário, acessibilidade e confiabilidade do sistema, interatividade e apresentação da informação.

The measurement of latent traits within the organizational field such as quality, effectiveness and learning has been conducted in several formats using a wide variety of quantitative methods, including Item Response Theory that consistently increased in organizational studies. The purpose of this article is to compare the hierarchical and non-hierarchical structures of three multidimensional models of ItemResponse Theory, based on the interface quality measurement in e-commerce sites. We compared the multiple unidimensional, compensatory multidimensional and bifactorial models, and also elaborated and applied 75 items in a sample of 441 e-commerce websites. As a result, we conducted a discussion of the latent construct, the quality in e-commerce and its multidimensional configuration to adjust and compare three multidimensional models.
