This study aims to evaluate the presence of abnormal returns due to stock splits or reverse stock splits in the Brazilian capital market context.

The event study technique was used on data from 518 events that occurred in a 30-year period (1987–2016), comprising 167 stock splits and 351 reverse stock splits.

The results revealed the occurrence of abnormal returns around the time the shares began trading stock splits or reverse stock splits at a statistical significance level of 5%. The main conclusion is that stock split and reverse stock split operations represent opportunities for extraordinary gains and may serve as a reference for investment strategies in the Brazilian stock market.

This study innovates by including reverse stock splits, as the existing literature focuses on stock splits, and by testing two distinct “zero” dates that of the ordinary general meeting that approved the share alteration and the “ex” date of the alteration, when the shares were effectively traded, reverse split or split.

The main objective of this study was to establish a model of competitiveness factors to measure the value of construction companies adequately.

A theoretical model of four main factors was developed, and they include human capital, ethical values, process innovation and financing. Information was collected from 18 construction companies in the city of Metropolitan Lima, collecting information on each of these factors. Through an analysis of the principal components, the weighting of each factor about the competitiveness of a construction company was determined.

The cost of person-hours, the cost of equipment to execute work, and the cost of materials used are the strongest indicators to measure the competitiveness of a construction company. On the other hand, the number of employees holding university degrees and the number of master builders holding technical degrees in the human capital factor also have a moderate weight in determining the competitiveness value of a company. The indicator of work delivered within the deadline also moderately affects competitiveness. Finally, the monthly debt payment indicator has a very small effect on the company’s competitiveness.

In conclusion, this study provides evidence of a competitiveness model with highly related factors on human capital, process innovation and ethical values as the most important in measuring competitiveness.

El objetivo principal de la investigación fue establecer un modelo de factores de competitividad para medir adecuadamente el valor de las empresas constructoras.

Se desarrolló un modelo teórico de cuatro factores principales, que incluyen el capital humano, los valores éticos, la innovación de procesos y el financiamiento. Se recolectó información de 18 empresas constructoras de la ciudad de Lima Metropolitana, recolectando información de cada uno de estos factores. A través de un análisis de componentes principales se determinó la ponderación de cada uno de ellos sobre la competitividad de una empresa constructora.

El costo de horas hombre, el costo de los equipos para ejecutar obras y el costo de material utilizado son los indicadores más fuertes para medir la competitividad de una empresa constructora. Por otro lado, la cantidad de empleados con títulos universitarios y la cantidad de maestros de obra con título técnico del factor de capital humano también tienen un peso moderado en la determinación del valor de competitividad de una empresa. El indicador de obras entregadas dentro de plazo también tiene un efecto moderado sobre la competitividad. Finalmente, el indicador de pago mensual de la deuda tiene un efecto muy pequeño sobre la competitividad de la empresa.

En conclusión, el estudio proporciona evidencia de un modelo de competitividad con factores altamente relacionados sobre el capital humano, la innovación de procesos y los valores éticos como los más importantes a la hora de medir la competitividad.

This study aims to investigate the influence of the theory of planned behavior (TPB), innovation and sustainability, through environmental awareness, in the formation of entrepreneurial intention (EI).

Based on the alignment between theoretical axes, such as the theory of planned behavior, adaptation–innovation theory and the environmental axis of sustainability, quantitative research was developed with students from Brazilian and Spanish universities. We obtained a sample of 686 university students enrolled in courses related to management in both countries. Data analysis included exploratory factor analysis and logistic regression.

Our results revealed that the constructs of TPB (personal attitudes and perceived behavioral control) influenced EI, excluding subjective norms. Innovation had an influence on the EI of students from both countries. In Brazilians, valuing change predicts EI, highlighting the importance of flexibility. Conversely, Spaniards emphasize originality, valuing uniqueness and creativity as drivers of EI. Sustainability, via environmental awareness, did not influence EI.

With this study, we aim to encourage policies and practices aimed at higher education institutions globally, to broaden the understanding about the importance of environmental, innovative and social studies and practices aligned with the context of entrepreneurship. The final aim is to enhance social and environmental benefits generated by future entrepreneurs.

This article delves into the contributions of Milton Santos (1926–2001) to the economic study of entrepreneurship. Santos made contributions to spatial economics, urbanization, and planning theories, being an important author to the field of regional and urban economics. His most famous idea is the “two circuits” of the urban economy. According to this approach, the urban economies in peripheral countries create two economic-urban circuits that are both distinct and connected. The superior circuit comes from the technological modernization and cultivates international relationships. High-value goods and networks and new technologies circulate through it. The inferior circuit works outside these networks. It consists of low-dimension activities from local populations. Santos elaborated this theory to understand urbanization in peripheral countries and to give voice to the ones left behind by the development process. He did not write directly on entrepreneurship. We argue, however, that his thoughts can be important to entrepreneurship studies. The entrepreneurship discourse, that had in Schumpeter one of its main sources, assumes that the entrepreneur has traits related to the superior circuit, such as access to resources and networks, which would not be available to entrepreneurs in the inferior circuit. We argue that Santos’ contributions can inform economic thought in entrepreneurship by calling attention to how literature can approach structural problems and contribute to making economics a more diverse discipline.

This paper aims to identify the role of blogs in helping women victims of intimate partner sexual violence to restore their self-integrity.

The authors’ research uses an interpretive stance, supported by motivational and “self” theories to analyze 33 blogs reporting the experiences of women in Brazil who suffered sexual violence perpetrated by an intimate partner.

This study identifies the reasons why women who suffer violence from intimate partners write blog posts. It also develops an analytical framework that bridges the gap between the design and use of IT-artifacts and the context of sexual violence from an intimate partner. Women who suffer violence from intimate partners look for blogs in order to find a safe space for expression, a knowledge hub and a social support network. Blogs play a pivotal role in supporting the journey of reconstructing their self-integrity.

The results help to understand the role of blogs in helping victims in vulnerable situations trying to restore their self-integrity. It also contributes to improve the design and functionality of such platforms as an important resource for social support networks.

This study shows the positive impact of blogs as a tool to support victims in the process of restoring their self-integrity.

This study aims to promote the use of digital artifacts such as blogs as a complementary instrument to fight violence against women.

The analytical framework used in this paper helps to understand the role of IT-artifacts in the context of sexual violence from an intimate partner.

This study examines three significant collaborative journalism projects in the Americas: The Panama Papers, from the United States-based International Consortium of Investigative Journalists (ICIJ); “América Latina, Región de Carteles,” by Colombian-based Connectas; and the first phase of the Brazilian-based project, Comprova, supported by Brazilian Association of Investigative Journalists (Abraji) and First Draft. The work investigates what encompasses collaborative journalism; and explores whether it is a recent phenomenon of the news ecosystem, a consequence of the institutional crisis of journalism, and if it is influenced by a network-based and platformed society. A mixed-method approach is applied in a three-stage analysis: (1) desk research; (2) quantitative content analysis; and (3) qualitative semi-structured in-depth interviews. To gain a broader picture of the organizations and their respective projects, documental and bibliographical research was carried out with a focus on data from press releases, corporate reports, and articles published on the websites of the organizations coordinating the projects. Furthermore, a quantitative content analysis of 10 news articles published by each of these collaboration partnerships was completed. Finally, qualitative semi-structured in-depth interviews were conducted with the directors, managers, and professional journalists’ part of the organizations and project. This study emphasizes the importance of collaborative practices, demonstrates how collaborative practices contribute to a new modus operandi of the news ecosystem; and considers why journalists and media organizations have turned to collaborative journalism as a model of production, circulation, and distribution of journalistic investigations.

Governments faced formidable challenges in coordinating public health responses to the COVID-19 pandemic. This study aims to enhance the understanding of effective organizational leadership during crises by investigating the factors influencing the turnover of health leaders during the COVID-19 pandemic in Brazil.

Using primary data encompassing all appointments and dismissals of federal and state health secretaries, this paper conducted a quantitative analysis of the relational and reputational factors that contributed to leader turnover during the COVID-19 pandemic. This paper also examined whether leaders’ management and public health experience increase the duration of tenure.

States encountered significant challenges in retaining experienced and effective leadership during the health emergency, primarily due to political conflicts in policymaking and, to a lesser extent, allegations of corruption. Furthermore, leaders with expertise in public health were found to be less likely to be removed from office. However, managerial experience did not prolong the tenure of state health secretaries during the emergency.

Since most health leaders have public health and management experience, the contributions of each factor to the duration of a secretary’s tenure are difficult to separate and analyze separately.

This study provides empirical insights into what factors drive health leader turnover during major health emergencies.

During major health emergencies, health leaders often strongly disagree with elected officials on the response. This paper test how crisis leadership theories help explain state health leaders’ duration in one of the world’s largest public health systems during the COVID-19 pandemic. This paper find that policy disagreements contributed to significant turnover.

To the best of the authors’ knowledge, this paper is the first that are aware of that uses novel primary data on public health executive leader characteristics and turnover causes in the context of the COVID-19 pandemic. It provides empirical evidence contributing to the crisis leadership literature by examining health leader turnover in one of the world’s largest public health systems.

This study aims to explore the ways in which management scholars affiliated with Peruvian universities navigate the tensions between global expectations and local realities in their research practices, drawing on their capitals and habitus.

Drawing on Bourdieu’s field theory, the authors analyse 25 in-depth interviews and a unique database of academic publications in the business and management field from 2000 to 2022. The analysis identifies the positions scholars occupy within the Peruvian management field and examines the factors influencing their research practices.

The authors find that the Peruvian management field is complex and unequal, where actors have different positions and interests, but are all influenced by a logic of academic dependency on the Global North. The authors identify three main positions held by scholars: transnational dominators, who accumulate greater resources and ignore local debates; dominated adaptors, who unsuccessfully try to imitate the dominant logic; and isolated innovators, who critique the dominant model but lack institutional support to develop alternatives.

This research presents an analysis of the Peruvian management field, a site often overlooked in international business studies. By examining scholarly practices, the authors reveal how academic inequalities are reproduced by the forces of globalization. The study underscores the urgent need for greater acknowledgement of regionally informed research, advocating for a more inclusive and diverse understanding in the field of management research.

This research seeks to provide methodological bases for the identification, documentation and critical reflection of good practices of architectural design in built heritage. These are applied explicitly to the School of Porto architects, which express a high sense of pedagogy and community practice in this field. The methodological approach defines the selection criteria for a georeferenced inventory and the procedures for in-depth analysis of adaptive reuse strategies.

The works included in the inventory were selected according to geographical, chronological, typological, qualitative and quantitative criteria. The cases chosen for in-depth analysis have been studied along four thematic axes to dissect all the intervention processes (previous state, design/construction and final state). This approach is supported by a cross-analysis of different sources (oral, written, graphic) and using drawing as a fundamental research tool.

The research has collected and disseminated up to 150 works by 44 architects, providing a comprehensive portrait of heritage intervention by the School of Porto over the past decades. The selection of 22 buildings for in-depth documentation reveals a particular sensibility toward the cultural values through a case-by-case approach based in deep knowledge of the preexisting context and the introduction of contemporary additions in continuity and harmonious relation with the environmental and sociocultural context.

This work provides a novel methodology suitable for further extension and adaptation to other case studies, as a first contribution to a more comprehensive “Atlas of Architectural Design in Built Heritage” with European case studies. The research aims to introduce new and deeper perspectives on reference works that may constitute pedagogy for the future practice of architects within contextual, inclusive and sustainable approaches.

The study aims to investigate how enterprise information systems strategies-enabled strategy-making (ISS-SM) influences organizational agility (OA) via the mediated role of IT-enabled dynamic capabilities (ITDC) under environmental dynamism (ED). The study also investigates natural country moderation associated with the business context of the countries where the respondents are located might influence these relationships.

The study aims to investigate how enterprise ISS-SM influences OA via the mediated role of ITDC under ED. The study also investigates natural country moderation associated with the business context of the countries where the respondents are located that might influence these relationships.

The results demonstrate that ISS-SM influences ITDC to gain OA independent of the ED level. Indian and Brazilian firms show no different effects in the relationship of the research model. However, post hoc analysis revealed that strong ISS-SM on OA is fully mediated by ITDC under higher ED with a substantial coefficient of determination, more prominent for Indian firms characterized by young-age and middle-size firms, agribusiness and government sectors.

The fundamental to enabling practice and praxis of the strategy-as-practice approach to OA gains mediated through ITDC in different business context conditions.

The research contributes to extending the literature on the enterprise information systems strategy and information technologies capabilities.
