The purpose of this study is to evaluate the efficiency of a Brazilian steelmaking company’s reheating process of the hot rolling mill.

The research method is a quantitative modeling. The main research techniques are data envelopment analysis, TOBIT regression and simulation supported by artificial neural networks. The model’s input and output variables consist of the average billet weight, number of billets processed in a batch, gas consumption, thermal efficiency, backlog and production yield within a specific period. The analysis spans 20 months.

The key findings include an average current efficiency of 81%, identification of influential variables (average billet weight, billet count and gas consumption) and simulated analysis. Among the simulated scenarios, the most promising achieved an average efficiency of 95% through increased equipment availability and billet size.

Additional favorable simulated scenarios entail the utilization of higher pre-reheating temperatures for cold billets, representing a large amount of savings in gas consumption and a reduction in CO2 emissions.

This study’s primary innovation lies in providing steelmaking practitioners with a systematic approach to evaluating and enhancing the efficiency of reheating processes.

This study aims at investigating the nexus between stock misvaluation, Fintech and COVID-19 via identifying the firm-level misvaluation of Fintech firms, and additionally examining how the COVID-19 pandemic has affected this misvaluation. This study further examines how the level of stock misvaluation has changed after the COVID-19 pandemic to shed more light on the pricing behavior of Fintech in a post-pandemic world.

The sample consists of all Fintech firms listed in the STOXX Global Fintech Index over the period (2014–2023). To empirically identify stock misvaluation, the authors apply the widely used approach of Rhodes-Kroph et al. (2005). Then, a series of fixed-effects regressions is conducted to investigate the impact of the COVID-19 pandemic on mispricing.

This study finds compelling evidence that Fintech stocks tend to be particularly mispriced during the COVID-19 pandemic. This evidence suggests that investors became more attracted to Fintech stocks, as being exposed to widespread adoption, usage and investment worldwide during the pandemic. Interestingly, the findings show that Fintech firms remain overvalued, even after the pandemic, which indicates that investors maintain their positive expectations for Fintech firms after the COVID-19 pandemic.

For investors and fund managers, the observed high valuation in the Fintech sector highlights its noticeable growth in the financial industry. The results also suggest that the impact of the COVID-19 pandemic on pricing behavior is asymmetric across the undervalued and overvalued Fintech stocks. This finding provides important insights for portfolio construction and investment strategies during the hard times of pandemics.

No previous work has been done on the effects of the COVID-19 pandemic on the prevailing levels of mispricing in Fintech stocks. Moreover, the findings provide novel insights into the pricing efficiency in the context of Fintech and extend the understanding of the long-term effects on Fintech firms in a post-pandemic world.

This paper aims to suggest a multi-theoretical explanation using a success story to explain psychological well-being (PWB) among employees of K.C, a small enterprise found in Uganda, a developing country in Africa.

The study used qualitative methodology. Based on in-depth interviews with K.C employees, a story was developed describing the practical experience, focusing on the context, actions, results and lessons learnt. Regarding the sample size, the saturation point was attained on the seventh participant.

Findings reveal that employees that possess psychological capital set targets and generate avenues that allow them to achieve set goals, with personal initiative that makes them proactive to accomplish work tasks and individual adaptability that enables them to adjust their emotions and behavior to fit in a complex working environment, which makes them to think, feel and act positively. Furthermore, several theories, including broaden and build, personal initiative and complex adaptive systems theory, explain the manifestations of PWB of employees in small enterprises.

The study was limited by focusing on the context of a small enterprise. Future research may investigate other study contexts whose findings might be different. In addition, the study being hypothetical lacked statistical testing. It would be a meaningful effort if future studies statistically tested the suggested model. Irrespective of the limitations, the findings of this study remain significant.

In practice, employees may replicate these findings to nurture PWB which eventually contributes to enterprises’ success. This could provide answers to the psychological challenges experienced by employees of small enterprises, especially in the African developing countries like Uganda where this is a major challenge. Specifically, the workers of K.C enterprise may depend on their PWB to deal with workplace challenges and sustain the enterprise’s performance.

Socially, there is need to embrace positive social relationships among employees at the work place which will translate into well-being of society.

This paper is exceptional because it uses a success story showing practical experiences of how PWB of employees in small enterprises is nurtured in Uganda. In addition, a multi-theoretical perspective is used to explain the manifestations in the story, which is the greatest contribution of this paper. Further, a conceptual model is still proposed, depicting psychological capital, personal initiative and individual adaptability as antecedents of PWB.
