title: Facilitators and Barriers faced by Mobile Payment Fintechs in the Brazilian Context

description: ABSTRACT Fintechs have created a new global financial reality, providing access to services that were previously provided only by banks. This article aims to identify facilitators and barriers faced by mobile payment fintechs for their entry and development in the Brazilian context. The research method was a single case study, whose unit of analysis was the mobile payment fintech sector in the Brazilian context, involving nine companies in this industry. As a result, we identified that several factors act as facilitators to the entry and development of fintechs, such as convenience and focus of their solutions, innovation in the use of technology, collaboration, and partnerships between fintechs. However, several barriers are faced in the emergence and development of these companies, such as regulatory issues, investment needs, difficulties in finding partners, and conflicts of interest with major players in the financial market. These results offer inputs to fintech entrepreneurs and suggest directions to regulators and public policymakers.

title: The Influence of Perceptions of Risks and Benefits on the Continuity of Use of Fintech Services

description: ABSTRACT New technologies have been driving the global financial market, including fintech companies, which provide disruptive financial services in which information technology is the key factor. The objective of this study is to identify which factors most influence intentions to continue using these companies’ products. To achieve this, research by Ryu (2018) was replicated. Our adopted model evaluates the weight of seven factors composing two latent variables - perceived risk and perceived benefit - in the continuity of use of these services. The data collection was performed through an electronic survey, distributed through social networks during May and June of 2019. The main results confirmed seven of the eleven initial hypotheses, highlighting that the perceived benefits, especially the economic ones, were relevant to early adopters and seamless transactions were relevant for late adopters. Surprisingly, perceived risk was not a determinant of continuance intention. One of the contributions of this study is that it indicates some possible demographic and behavioral characteristics of Brazilian fintech consumers, opening up space for a better understanding of the market and service improvements.

title: Understanding the Integration of Socio-Technical Actors for Sharing and Sustainable Urban Mobility

description: ABSTRACT In the search for sustainability and urban reconfiguration, this research analyzes a business model used in sustainable urban mobility initiatives that integrates public and private agents (socio-technical actors - ST-actors) in Fortaleza (Brazil). An integrated case study was carried out with two initiatives: VAMO Fortaleza (e-carsharing) and Bicicletar (bike sharing). Interviews were conducted with the protagonist ST-actors, and documents were analyzed focusing on shared urban mobility. We observed that the initiative implementation integrates ST-actors through public-private partnerships. Based on that, a schematic model was designed to illustrate ST-actor integration as a business model that can be replicated in other contexts using sharing economy principles. In the context of the urban mobility reconfiguration focused on sustainability, we explore a case which has been internationally recognised and we present an underexplored theme about sharing economy initiatives that can be practised.

title: Attributes of a Relationship Management Model for the Public Sector (CiRS Exec)

description: ABSTRACT The New Public Management has encouraged the adoption of managerial tools by the public administration. In this context, the Citizen Relationship Management (CiRM) strategy allows for the improvement of the relationship with citizens and encourages citizenship. Thus, this research aims at identifying evidence for validity and reliability of a citizen relationship scale (CiRS Exec) for the Federal Executive Branch in Brazil, as well as a citizen’s satisfaction index. Exploratory and confirmatory factor analyses have been used, through structural equation modeling. The measurement model has presented good adjustment and a unifactorial structure scale named ‘Citizen Relationship’, comprising 13 items.

title: Influence of the Diagnostic and Interactive Use of the Budget on Managerial Performance Mediated by Organizational Commitment

description: ABSTRACT The objective of this study is to evaluate the influence of the diagnostic and interactive use of the budget on managerial performance, as mediated by organizational commitment. A survey was carried out using Brazilian textile industry companies as a population, and the sample consists of 133 respondents to the questionnaire. Structural equation modeling was used to test the hypotheses. The results showed that the diagnostic and/or interactive use of the budget influences organizational commitment, as well as influencing managerial performance. The organizational commitment variable had a total mediating effect on the relationship between the use of budgetary control system and managerial performance, indicating that forms of budget use affect managerial performance only when managers are committed to the organization. Based on the results, we concluded that forms of budget use had influence on organizational commitment and on the managerial performance in the surveyed companies. These results advance the literature as they reveal that the diagnostic use and interactive use of the budget are antecedent variables of organizational commitment, leading to behaviors at work that can contribute to increasing managerial performance.

title: Intellectual Structure Of Ongoing Studies on Business Schools

description: ABSTRACT We examined the extant research on Business Schools (B-Schools) in an attempt to understand the intellectual structural influences in mainstream research, as well as the evolution and trends in research. Through a bibliometric study of co-citation and bibliographic coupling, supported by factor and network analyses of a sample of 493 articles, we examined 76 selected articles and their references. The results indicate that critiques of B-Schools influenced mainstream works. We found three primary sources of criticism at the intellectual level: Theory and Practice Gap, Social Relevance, and Curricula and Practice. The mainstream works identified six different topics: B-School Relevance, Teaching Relevance, Relevance to Practice, Curricula Relevance, B-School Evolution, and Influence, and Reputation. The longitudinal analysis identified four trends: Relevance to Practice, Social Relevance, Academic-Practitioner Divide, and Teaching Relevance. Through our bibliometric research, we contribute to the B-Schools research in two ways. It enabled the identification of works and themes that influenced reflections on B-Schools, as they influenced the ongoing research, and consequently, the research trends. Furthermore, the results serve as possible orientations for B-School managers.

title: Open Innovation Strategies and Appropriability in Knowledge-Intensive Business Services: Evidences and Implications in the Brazilian Context

description: ABSTRACT This paper analyzes open innovation strategies and their implications on appropriability and performance in Knowledge-Intensive Business Services (KIBS) firms which operate in the Brazilian market. This is cross-sectional research relying on the survey method. Data was collected through a questionnaire applied to 345 firms that provide Information Technology (IT) and Business Management Consulting services. Cluster analysis was the main technique employed for data analysis. The results showed that KIBS firms, whose inbound and outbound flows difference is small, eventually use appropriation mechanisms to a greater extent and adopt the selective revealing strategy more intensely. It is concluded that Brazilian KIBS firms adopt inbound knowledge flows more intensely, and that firms herein labelled as “neutral” presented greater appropriation and innovation performance than “externalizing”, “internalizing” or “very internalizing” firms.

title: Environmental Regulations, Green Innovation and Performance: An Analysis of Industrial Sector Companies from Developed Countries and Emerging Countries

description: ABSTRACT This study analyzes whether the rigor of environmental regulations encourages industrial companies in developed and emerging countries to invest in Green Innovation (GI), and what is the impact on financial performance. The sample was composed of 159 industrial companies, listed in the Financial Times’ 500 largest companies by market value in 2015. For the analysis, Structural Equation Modeling was used to verify the relationship between the variables. The main results were that the strictness of the countries’ environmental regulations, and the size of the companies had a statistically significant positive impact only on construct GI2, composed of the variables Global Compact and environmental investments. Countries competitiveness did not positively influence companies’ GI efforts, and the degree of internationalization of companies had no significant effect on any of the GI constructs. Furthermore, the efforts of companies in GI do not reflect positively on their financial performance.

title: Do State-owned Enterprises in Brazil Require a Risk Premium Factor?

description: ABSTRACT Despite the extensive privatization achievements over the last decades, government ownership of publicly traded companies remains pervasive around the world. Consistent with past evidence of structural change in the beta coefficient during financial crises, the more recent economic recession of 2014 to 2016 in Brazil presents an opportunity to demonstrate the disadvantages of allocating investment in companies that are publicly traded, but are controlled by the government. Constructing a portfolio of publicly traded State Owned Enterprises, we find that the financial crisis produced a significant increase in risk exposure, results that were much more pronounced when compared with a portfolio of privatized companies. The results also indicate that, in addition to a market factor, the poor performance can be explained by controllership. We believe this study adds to the long-standing debate on whether state-owned firms perform worse than private firms, with higher volatility and lower returns, particularly, during a period of financial crisis.

title: Opacity in Hedge Funds: Does it Create Value for Investors and Managers?

description: ABSTRACT This paper investigates if opacity (as measured by derivatives usage) creates value for investors and the managers of hedge funds that charge performance fees. Since we do not identify a positive relation between opacity and managers’ revenue, it is not possible to state that opacity is a source of manager’s value creation for hedge fund investors and managers. However, considering that opacity is positively associated with risk-taking and negatively related with investors’ adjusted returns, we suggest policies aiming at protecting investors, especially those less qualified. We examine a unique and comprehensive database related to the positions in derivatives taken by managers, which was enabled due to specific disclosure regulatory demands of the Brazilian Securities Exchange Commission, where detailed information on hedge funds’ portfolio allocation should be provided on a monthly basis.

title: Fundamentalist Signals in Volatility Scenarios: Evidence in the Brazilian Stock Market

description: ABSTRACT This article investigates whether the usefulness of fundamentalist signals to predict returns are altered in context of high volatility and also considering the sensitivity of assets to the IVol-BR volatility index. In times of high volatility, investors could make their decisions based on risk aversion and not only on the fundamentals signals of companies. In addition, it is possible to see how different delays in fundamentalist signals are related to future returns. The methodological choice is for estimators in panel data for the analysis of non-financial companies that have shares traded on B3 - Brasil, Bolsa, Balcão - in the period from 2011.3Q to 2018.2Q. The results show evidence of changes in the explanatory capacity of fundamentalist signals in different volatility scenarios, and for different sensitivities to IVol-BR. This finding may impact the decision-making of managers and investors as it enables the design of investment strategies based on fundamentalist signals adhering to different risk scenarios.

title: Economic Assessment of Brazilian Public Ports: Value-Based Management

description: ABSTRACT Ports are among the main links of the international logistic chain and, consequently, an important element of economic development. Thus, this study aims to investigate the economic and financial results of Brazilian public ports by evaluating their ability to generate economic value. Therefore, we assessed the port authorities with traditional financial indicators as well as with Economic Value Added (EVA) indicators, aiming to assess companies’ ability to create wealth for ports’ capital investors. Findings indicate that, despite the satisfactory financial situation, such results are not due to the businesses’ operation, but most likely due to governmental subsidies. Port authorities also showed inefficiency to remunerate the capital invested. The study contributes to the literature by shedding light on the discussion about the economic and financial management of public ports and the use of public resources in the port sector.

title: Business Analytics and Sociomateriality: A Study on the Practice of Revenue Management in an Airline Company

description: ABSTRACT The aim of this article is to address the Business Analytics (BA) practice based on the sociomateriality approach within the Revenue Management (RM) context of an airline. The study proposes that BA is an active engagement process which is set between analysts and business managers according to their sociomaterial imbrication with analytical data and tools, which areused to generate new insights. The discussion is substantiated by the theoretical articulation of BA as applied to RM based on the sociomateriality approach, which acknowledges the synergetic interaction between human and material dimensions by keeping their distinction from intentionality. The empirical investigation followed a qualitative design supported by non-participatory observation, interview and document research, which were the data collection techniques. The collected data was analyzed through spiral analysis associated with a practices’ description and analyses framework. Results have supported the BA proposition by evidencing the human/material dimension entanglement to produce BA-practice specificities.

title: The Influence of Company Size on Energy Management Systems Adoption: A System Dynamics Model

description: ABSTRACT Isomorphism can be understood as the process that leads one population to resemble another in the same environmental conditions. Isomorphic pressures are felt differently depending on the size of the organization and can disturb the adoption of Energy Management Systems, such as ISO 50001. Given institutional differences, how can government´s coercive pressures impact the spread of ISO 50001 in each size group? To what extent can they influence the overall spread of certification? This article applies the Bass diffusion model to assess the ISO 50001 certification over the 2016-2040 period, using a system dynamics modeling approach. It proposes an extension of the diffusion model related to market stakeholder pressure, based on institutional theory. The results showed that financial and fiscal incentives provided the most significant impact on the overall number of certified industries. Large companies are the most relevant segment for certification without additional policies, while smaller ones benefit significantly from incentive programs. This study reinforces the relevance that stakeholders have in promoting greener standards and initiatives, and offers useful lessons on the dynamics of adopting energy management systems.

title: INDIRECT DECOMPRESSION BY LATERAL FUSION: ANALYSIS OF SAGITAL ALIGNMENT

description: ABSTRACT Objective: To verify the effectiveness of indirect decompression after lateral access fusion in patients with high pelvic incidence. Methods: A retrospective, non-comparative, non-randomized analysis of 22 patients with high pelvic incidence who underwent lateral access fusion, 11 of whom were male and 11 female, with a mean age of 63 years (52-74), was conducted. Magnetic resonance exams were performed within one year after surgery. The cross-sectional area of the thecal sac, anterior and posterior disc heights, and bilateral foramen heights, measured pre- and postoperatively in axial and sagittal magnetic resonance images, were analyzed. The sagittal alignment parameters were measured using simple radiographs. The clinical results were evaluated using the ODI and VAS (back and lower limbs) questionnaires. Results: In all cases, the technique was performed successfully without neural complications. The mean cross-sectional area increased from 126.5 mm preoperatively to 174.3 mm postoperatively. The mean anterior disc height increased from 9.4 mm preoperatively to 12.8 mm postoperatively, while the posterior disc height increased from 6.3 mm preoperatively to 8.1 mm postoperatively. The mean height of the right foramen increased from 157.3 mm in the preoperative period to 171.2 mm in the postoperative period and that of the left foramen increased from 139.3 mm in the preoperative to 158.9 mm in the postoperative. Conclusions: This technique is capable of correcting misalignment in spinal deformity, achieving fusion and promoting the decompression of neural elements. Level of evidence III; Retrospective study.

title: Spatial Dependency of Eco-Efficiency of Agriculture in São Paulo

description: ABSTRACT This research presents an eco-efficiency index for the municipalities of São Paulo, indicating how much it would be possible to maximize economic and environmental objectives, taking into account the best practices for the municipalities of this region. In this vein, we used the Data Envelopment Analysis method with directional distance functions based on the classic variables of multiproduct production function and the internalization of two externalities (one positive and one negative). The study also used the tools of exploratory spatial data analysis to verify the spatial autocorrelation and spatial heterogeneity of the calculated index. The results indicate that, on average, the analyzed municipalities are able to expand the production and forested areas by 59% and also to reduce degraded areas and inputs in the same proportion. Spatial analysis demonstrated the existence of spatial heterogeneity and autocorrelation between municipalities and the formation of large clusters. Based on these results, priorities for environmental intervention in the state are defined.

title: UNKNOWN PRIMARY TUMOR SITES IN SPINAL METASTASIS

description: ABSTRACT Objective: The goal of the study was to report the prevalence of spinal metastasis with unknown primary tumor, clinical features, treatment results and patient survival. Methods: A retrospective evaluation of 103 patients with spinal metastasis and epidural compression, who underwent surgical treatment between March 2009 and August 2015. The prevalence of metastatic spinal tumor with unknown primary tumor was evaluated, as well clinical features, survival and treatment results. Results: Of 103 patients with spinal metastasis and epidural compression, seven patients (6.8%) with unknown primary tumor site were identified; five (71.4%) male and two (28.6%) female, with ages ranging from 37 to 67 years (50.7 years). The metastasis was located in the thoracic spine in six of the patients (85.7%) and in the cervical spine in one (14.3%). The mean survival time was 44.8 days. Conclusion: Spinal metastasis with unknown primary tumor was found in 6.8% of patients. The prognosis and outcomes were poor, and patients had poor survival rates. Level of evidence III; Experimental study.

title: Country or Brand: What Matters to Younger Millennials?

description: ABSTRACT Our objective is to compare the effects of country of origin (COO) and brand on Younger Millennials’ (YM) willingness to buy global brands. We chose the United States, because it is the country of origin for the most valuable global brands. We approached Apple, Levi’s, and McDonald’s because they are iconic brands both in the US and globally. We tested constructs related to the country of origin and brand and then conducted a survey with 367 YM (17-23 years old) as potential brand consumers. We applied a structural equation model to analyze the impacts of these constructs on their willingness to buy. Results indicate that the way YM connect themselves to the brand is more important than the way they perceive or feel about the brand’s country of origin. We studied real brands within their target market and, in a current context, translated constructs for application in day-to-day consumer situations, while seeking discoveries that can be widely applied in the field of international marketing.

title: POSTERIOR VERTEBRAL COLUMN RESECTION (PVCR): A SAFE AND EFFECTIVE OPTION TO TREAT KYPHOSIS FROM SPINAL TUBERCULOSIS

description: ABSTRACT Objective: To evaluate the clinical and radiological results of posterior vertebral column resection (PVCR) for the treatment of kyphosis from spinal tuberculosis. Methods: Retrospective study of a series of 14 cases, 9 female and 5 male, with a mean age of 28 years (1 to 64) at the time of surgery, with spinal tuberculosis with mean kyphosis of 56.42° (2° to 95°). Results: All patients underwent surgical treatment with PVCR, with a mean number of 2.57 (1 to 6) resected vertebrae and a mean number of instrumented vertebrae of 6.14 (4 to 8). The mean kyphosis correction was 64% after up to one year of follow-up. Prior to surgery, eight patients had signs of spinal cord impairment (ASIA score ranging from A to D), and six did not present any deficit of strength or sensory function (ASIA E). There was no neurological worsening and everyone with deficits improved by at least one degree on the scale. In the postoperative follow-up, bone consolidation was observed in all patients, except one. Among the intra- and postoperative complications, pleurotomy was the most prevalent. Conclusion: Posterior vertebral column resection has proven to be a safe and effective option for the treatment of kyphotic deformity from spinal tuberculosis. Level of evidence IV; Therapeutic studies - Investigation of treatment results.
