Design / Methodology / Approach: We use the SSF Systematic Search Flow method, which is applied in systematic and integrative reviews. Results: An entrepreneurial university, committed to the development of its region, is the key factor in achieving regional innovation, a key institution in knowledge-based societies. In the age of knowledge, the university is as important as industry and government; fundamental for the development of knowledge and innovation. As a result, we identified research challenges and opportunities, contributing to the construction of a panorama of Brazilian scientific production in international journals on the themes entrepreneurial university and third mission. Limitations of the investigation: The most important limitation in this study was the long-time collection of research data. Practical implications: Universities must strengthen their relationship with industry and government to transfer knowledge and, at the same time, demonstrate their contribution to the community, fulfilling their third mission, as a vector for regional socioeconomic growth. Originality / Value: We see the opportunity to consolidate studies on the relationship between the third mission and the entrepreneurial university appropriate to the Brazilian reality.","PeriodicalId":54139,"journal":{"name":"Brazilian Journal of Operations & Production Management","volume":"1 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82307930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this study is to construct an explanation on how this phenomenon manifests itself in an engineering company. Design / Methodology / Approach: The qualitative approach was adequate to understand how elements of individual narratives were related to the company culture. The analytical procedures were based on the systematics of Grounded Theory. Texts written in 2016 by the employees about their work for applying for a knowledge management program within their company were the source of this corpus. Results: The interpretation of the data has shown that four aspects form sets of filters that construct the culture, in a non-homogeneous learning process. In the intersection of these sets we can find essential values that motivate the employees of different positions, activities, regions, genders and ages. Limitations of the investigation: The knowledge management program asked for overcoming stories which is a limiting factor since employees have chosen successful stories from their work to tell. Practical implications: The findings allow us to infer that changing or reinforcing the current values implies the promotion of action that permeates these filters and are simultaneously not in the purview of the company’s management. Originality / Value: The study also pointed out the pertinence of the use of storytelling for knowing the actors’ interpretation about the values of the organization.","PeriodicalId":54139,"journal":{"name":"Brazilian Journal of Operations & Production Management","volume":"56 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75153902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Method adapted from graph theory concepts with bibliometrics, especially the h-index. From the center of this index will be listed the most used airports to define the Brazilian central network and thus determinate the type h-index of Brazil. Results: The main airports in the results represent more than 50% of the homologated flights in Brazil. Limitations of the investigation: The centrality measure presents the situation at the moment when the data were analyzed. In the original h-index this notion reflects a history of the articles published by each author, but in the case of airports the market dynamics changes the behavior of the network.

{"title":"CORPORATE GOVERNANCE ISSUES IN THE PUBLIC SECTOR: BOARD PERSPECTIVE AND PECULIARITIES","authors":"P. Y. Lartey, Yusheng Kong, S. O. Afriyie, R. Santosh, F. Bah","doi":"10.14488/bjopm.2020.001","DOIUrl":"https://doi.org/10.14488/bjopm.2020.001","url":null,"abstract":"Fatoumata Binta Maci Bah mariamatimbi@yahoo.com School of Biological Engineering and Life Sciences, Jiangsu University, Zhenjiang 212013, China ABSTRACT Goal: The objective of the paper is to extend the discussions on corporate governance to the public sector and examine good governance from a Ghanaian institutional context. Design / Methodology / Approach: Literature is based on relevant theoretical concepts and seven explanatory variables of corporate governance. Primary data was abstained through structured questionnaires administered to public servants from the Ministries, Departments and Agencies– MDA’s in Accra. Ordinary Least Square multiple regression was employed to analyze a total valid sample of 568. The findings represent the opinions of board of directors, internal auditors, senior management and employees. Results: The empirical result shows that audit committees, leadership, board effectiveness, accountability and directors’ qualification are strong determinants of good governance in public organizations. However, board size has no impact on good governance when board independence is negative. There is evidence that international corporate governance principles are reasonably visible without any significant deviations. Limitation of the investigation: The study is empirically limited with the absence of key variables such as corruption, ethnicity and tribal politics in public organizations in Ghana. These are major factors associated with institutional governance in developing countries. Practical implications: The study observed a negative relationship between board independence and good governance attributed to lack of board diversity. The study implies that gender balanced boards composed of higher ratio of female directors could enhance decision-making and guarantee board effectiveness. Originality / Value: The study emphasizes that public and private organizations share almost similar governance indicators, considering the model estimation. There is evidence that corporate governance is gaining popularity in the public sector, a discussion that is often limited to the private sector. The study contributes to the limited existing findings on the subject from a Ghanaian institutional context. Finally, the results validate many empirical opinions about the negative relationship between good governance and board size from different institutional environments.","PeriodicalId":54139,"journal":{"name":"Brazilian Journal of Operations & Production Management","volume":"19 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87652399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For such an answer it was found that the first published article was on the subject date from 2006 and 2013 there was a steady increase in the number of publications. Many publications mentioned the use of CE in the supply chain through the management of the green supply chain. The country with more publications about the area in the United Kingdom with 19,1% of papers. Moreover, publications are generally about IT product and service supply chains. Design/Methodology/Approach: Systematic literature review based on bibliometric theory and social network analysis, linking Circular Economy and Supply Chain. Results: The articles do not point to studies on a specific supply chain, but only stress the importance of applying Circular Economy to the supply chain to mitigate the environmental impact of materials and products along with the flow from the production process to end consumers. Limitations of the investigation: This paper contributes by analysing the international literature about the selected topics. In a future research agenda, this study could be applied to survey-based research to answer the research propositions suggested. Practical implications: The research helps scholars to identify the main hot topics about Circular Economy and Supply Chain, main authors and papers. Also, can help managers to develop Circular Economy business models to improve and mitigate the environmental impacts on the production and supply chain.

Design / Methodology / Approach: Forecasting methods tested include the use of multivariate and univariate neural networks (FNN and LSTM), exponential smoothing and ARIMA models. Results: Results show that the use of ARIMA models to forecast on the dataset is the best default method to apply, and is the only forecasting method that consistently beats a simple naïve no-change model. Limitation of the investigation: There was a focus on evaluating neural networks. This limited resources available to evaluate other forecasting methods. There is no guarantee that it would not be possible to find neural networks capable of yielding better forecasts than the ones achieved by the best performing methods in this research. Practical implications: The broadest possible implications of the results are that the best default method to forecast industrial machinery time series is the use of ARIMA models. Additionally, neural networks are not capable of beating methods well stablished within the forecasting community, namely ARIMA models. Originality / Value: To the best of the authors’ knowledge, there is a scarce amount of published evaluations of multiple forecasting methods on data from real machines. This knowledge is useful for the understanding of the best forecasting methods available for the estimation of machine’s RUL using sensor time series.","PeriodicalId":54139,"journal":{"name":"Brazilian Journal of Operations & Production Management","volume":"26 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90221711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As different oils and products require different amounts of hydrogen, their use optimally is an essential tool for refinery production scheduling. A comparison was made between the different approaches used in optimization via mathematical programming. Design / Methodology / Approach: One of the most used methods for hydrogen network optimization is through mathematical programming. Linear and non-linear models are discussed, positive aspects of each formulation and different initialization techniques for non-linear modeling were considered. Results: The optimization through the linear model was more satisfactory, taking into account the payback of the new proposed design, combined with the use of compressor rearrangement, which reduces the investment cost. Limitations of the investigation: The objective function chosen is based on the operational cost, but another approach to be considered would be the total annual cost. In addition, the parameters related to costs are obtained from the literature and may change over the years. Practical implications: The proposal is to discuss the main aspects of each model, showing which models more robust and easier to converge are capable of providing competitive results. Also, different initialization techniques that can be used in future works. Originality / Value: The main contribution is the relationship between hydrogen management and production scheduling and for that, a discussion is made about possible formulations.
