Abstract
Purpose
The purpose of this study is to stabilize the rotating speed of the permanent magnet direct current (PMDC) motor driven by a DC-DC boost converter under mismatched disturbances (i.e.) under varying load circumstances like constant, frictional, fan type, propeller and undefined torques.
Design/methodology/approach
This manuscript proposes a higher order sliding mode control to elevate the dynamic behavior of the speed controller and the robustness of the PMDC motor. A second order classical sliding surface and proportional-integral-derivative sliding surface (PIDSS) are designed and compared.
Findings
For the boost converter with PMDC motor, both simulation and experimentation are exploited. The prototype is built for an 18 W PMDC motor with field programmable gate arrays. The suggested sliding mode with second order improves the robustness of the arrangement under disturbances with a wide range of control. Both the simulation and experimental setup shows satisfactory results.
Originality/value
According to software-generated mathematical design and experimental findings, PIDSS exhibits excellent performance with respect to settling speed, steady-state error and peak overshoot.

Abstract
Purpose
Given the limited understanding of the process of transgenerational entrepreneurship and that knowledge is a fundamental antecedent of entrepreneurial endeavors, this study aims to shed light on how entrepreneurial families (EFs) nurture entrepreneurship across generations, which knowledge is required within the EF to spur new entrepreneurial activities, and how is this knowledge acquired.
Design/methodology/approach
Considering the paucity of empirical evidence on the topic under investigation and the related exploratory nature of this study, the authors adopted a qualitative approach by conducting a case study on an Italian wine-making family business.
Findings
The case analysis reveals that EF members are required to acquire different types of knowledge at different generational stages to spur new entrepreneurial activities, specifically technical knowledge in the second generation and business knowledge in the third generation. Moreover, the data analysis shows two mechanisms, namely, trust among generations and role separation, that, during both generational transitions, enabled and empowered the younger generations to exploit their knowledge to explore entrepreneurial opportunities and engage in new entrepreneurial activities.
Originality/value
This study provides novel insights into the role of knowledge in transgenerational entrepreneurship, particularly looking at knowledge acquired by EF members across generations. Accordingly, this research contributes to the literature streams of transgenerational entrepreneurship, knowledge management in family businesses and broader knowledge management research.

Abstract
Purpose
“Dirty work” is an embodied, emotional activity, and may best be expressed through narrative thick description. The purpose of this paper is to employ creative analytic techniques through a “messy text” for better understanding the tacit knowledge and emotionality of dirty work and dirty research. The vignettes, based upon ethnographic fieldwork with US Border Patrol agents, viscerally reveal the embodied emotions of dirty work and doing dirty research.
Design/methodology/approach
The research draws on a two and a half year ethnography of the US Border Patrol in which the first author engaged in participant observation, shadowing, and interviews. Based upon the iterative data analysis and narrative writing techniques using verbatim quotations and field data, the essay provides a series of vignettes that explore the multi-faceted feelings of dirty work.
Findings
Tacit knowledge about dirty work is unmasked and known through experiences of the body as well as emotional reactions to the scene. A table listing the emotions that emerged in these stories supplements the narrative text. The analysis shows how communication about emotions provides a sense-making tool that, in turn, elucidates both the challenges and the potential highlights of doing dirty work. In particular, findings suggest that emotional ambiguity the “moral emotions” of guilt and shame may serve as sense-making tools that can help in ethical decision making and a re-framing of challenging situations.
Originality/value
A field immersion alongside dirty workers, coupled with a creative writing approach, provides access to the fleeting, embodied, and fragmented nature of tacit knowledge – answering the questions of what dirty work feels like. The essay provides a behind the scenes exploration of US Border Patrol agents – a profession that is alternately stigmatized or hidden from public view. Finally, the piece provides a self-reflexive account of the messy realities of conducting “dirty research” in a way that is open ended and embodied.

The study investigates how cultural festival attendees’ familiarity and involvement may influence their overall satisfaction and future behavioral intentions towards the festival.
Abstract
Purpose
The study investigates how cultural festival attendees’ familiarity and involvement may influence their overall satisfaction and future behavioral intentions towards the festival.
Design/methodology/approach
A path analysis is used to test the proposed model. The Sobel test is performed to determine the mediating role of attendee satisfaction on future behavioral intentions.
Findings
Attendee familiarity positively and directly impacts attendee involvement. Attendee satisfaction mediates the relationship between involvement and intention to return to the festival. The findings did not demonstrate a relationship between attendee involvement and intention to recommend the cultural festival. Attendees’ intention to return to the festival positively and directly impacts intention to recommend the festival.
Practical implications
For repeat cultural festival attendees, satisfaction is influenced by festival familiarity and involvement. As attendees become more satisfied with their festival involvement, their decision to return to the festival increases. The mediation effect of satisfaction indicates that this should be a priority, as it fully mediates the relationships. However, this is not the case as it relates to the intentions to recommend the festival.
Originality/value
The study contributes to literature on the impact of familiarity and involvement on repeat attendee satisfaction levels and how these relationships influence attendees’ decisions to return or recommend the festival. It is one of the first studies that investigates actual behavior of festival attendees, specifically in the context of an African-American cultural festival.

Abstract
Purpose
This study analyzes the influence of institutional and macroeconomic factors, in addition to firm-level factors, on the capital structure of listed industrial Latin American (LATAM) companies. The objective is to provide empirical evidence on LATAM firms from (1) the perspective of the traditional trade-off and pecking order theories and (2) from approaches that introduce the impact of institutional and macroeconomic factors into the analysis.
Design/methodology/approach
The empirical analysis adopts an econometric methodology using panel data on companies from Argentina, Brazil, Chile, Colombia, Mexico and Peru from 2008 to 2018.
Findings
The results indicate that, in addition to the firm-level characteristics, the institutional and macroeconomic characteristics of the countries influence the capital structure of LATAM companies.
Research limitations/implications
The study presents some limitations. It is mainly focused on listed companies sourced from only six LATAM countries due to a lack of data. It would be advisable to carry out similar studies with corporate governance factors, family businesses and small and medium-sized enterprises (SMEs).
Practical implications
The results can serve as a reference for economic agents and professionals, encouraging them to consider the evolution of institutional and macroeconomic variables when making decisions. Academically, our findings verify the validity of conventional theories and the relevance of incorporating external institutional variables into the capital structure framework.
Originality/value
The importance of this research lies in analyzing the capital structure of companies in a little-explored geographic area, LATAM, including institutional and macroeconomic factors and using the new Orbis database.
Propósito
Este estudio analiza la influencia de los factores institucionales y macroeconómicos, además de los factores a nivel de empresa, en la estructura de capital de las empresas industriales cotizadas latinoamericanas (LATAM). El objetivo es proporcionar evidencia empírica sobre las empresas latinoamericanas desde (1) la perspectiva de las teorías tradicionales trade-off y pecking order, y (2) desde los enfoques que introducen el impacto de los factores institucionales y macroeconómicos en el análisis.
Diseño/metodología/enfoque
El análisis empírico adopta una metodología econométrica, utilizando datos de panel de empresas de Argentina, Brasil, Chile, Colombia, México y Perú, de 2008 a 2018.
Hallazgos
Los resultados indican que, además de las características a nivel de empresa, las características institucionales y macroeconómicas de los países influyen en la estructura de capital de las empresas latinoamericanas.
Limitaciones/implicaciones de la investigación
El estudio presenta algunas limitaciones, principalmente se centra en empresas cotizadas provenientes de solo seis países de LATAM, debido a la falta de datos. Sería recomendable realizar estudios similares con factores de gobierno corporativo, con empresas familiares y PYMES.
Implicaciones prácticas
Los resultados pueden servir de referencia para los agentes económicos y profesionales, animándolos a considerar la evolución de las variables institucionales y macroeconómicas a la hora de tomar decisiones. Académicamente, nuestros hallazgos verifican la validez de las teorías convencionales y la relevancia de incorporar variables institucionales externas en el marco de la estructura de capital.
Originalidad/valor
La importancia de esta investigación radica en analizar la estructura de capital de empresas en un área geográfica poco explorada, LATAM, incluyendo factores institucionales y macroeconómicos y utilizando la nueva base de datos Orbis.

Abstract
Purpose
Forests are negatively affected from rapid world population increase and industrialization that create intense pressures on natural resources and the possibility of an achieving circular economy. Forests can be considered as essential resources for providing sustainable society and meeting the requirements of future generations and circular economy. Therefore sustainable production tools as part of circular economy can be handled as one of the basic indicators for achieving circular economy. Accordingly the main purpose of this study is developing a novel rough – fuzzy multi-criteria decision-making model (MCDM) for evaluation sustainable production for forestry firms in Eastern Black Sea Region.
Design/methodology/approach
For determining 18 criteria weights a novel Rough PIPRECIA (PIvot Pairwise RElative Criteria Importance Assessment) method is developed. Eight decision-makers (DMs) participated in the research, and to obtain group rough decision matrix, rough Dombi weighted geometric averaging (RNDWGA) operator has been applied. For evaluation forestry firms fuzzy MARCOS (Measurement of alternatives and ranking according to COmpromise solution) method was utilized.
Findings
After application developed model the fourth alternative was found as the best. Sensitivity analysis and comparison were made to present the applicability of this method.
Originality/value
Development of novel integrated Rough PIPRECIA-Fuzzy MARCOS model with emphasis on developing new Rough PIPRECIA method.

Abstract
Purpose
This paper points out that common human resource manageement (HRM) research and practice have overlooked employee's class of origin. Workers' class of origin can be seen as “the elephant in the room” in current HRM, being that it significantly affects organizational decision-making with negative social (increased class-based inequality) and organizational (inefficient allocation of human re-sources) effects.
Design/methodology/approach
The paper summarizes the partial, fragmented and multi-disciplinary literature on HRM and employees’ social class of origin.
Findings
The paper shows how recruiting, selection, training and development practices systematically reinforce class-based inequality by providing high-class employees with more resources and opportunities compared to low-class employees.
Practical implications
The paper provides sustainable HR practitioners, educators and researchers with recommendations on how to address employees' social class of origin, improving organizational competitive advantage and reducing class-based inequality at the societal level.
Originality/value
The paper focuses on a topic which, in diversity management, is an elephant in the room (i.e. workers social class of origin).

Abstract
Traditionally, organizational theory has been a receptacle of methods and mechanisms from network theory. In this paper, we argue that organizational theory can also be an active contributor to network theory’s conceptual development. To that end, we make explicit a theoretical strategy that has only been used informally by network theorists so far, which – following Vaughan (2002) – we refer to as analogical theorizing. Using the basic correspondence between dyadic relationships as the most minimal form of “organization,” we show that processes and mechanisms extracted from various theoretical strands of organizational theory can be mapped onto the dynamics of social relationships. This allows us to build novel theoretical insight as it pertains to issue of relationship emergence, maintenance, and decay in social networks.
