In this paper we aimed to find an answer to the question: is control still important for modern organization in order to favor achievement of superior performances? We have tried to find answer to this question through an empirical investigation in the field of strategic alliances. Thus, we have analyzed the relationship between alliance monitorization and control and various measures of alliance performances. Based on a statistical analysis of data provided by 46 best performers medium and large companies operating in Romania, we found that control is still important for superior performances, whether productivity (e.g. revenues growth) or innovation related performances (e.g. new product development). We used multiple multilinear regressions and found positive associations between alliance monitorization and control, structural control factors and productivity, respectively innovation related performances. Surprisingly, we found that control process factors are not associated with superior innovation performances and for productivity related performances there is only a low intensity association. In terms of explanatory potential of regression models, in five models out of six, the control factors significantly explained why some companies extracted higher value from their portfolio of strategic alliances, as compared to companies extracting more modest value. The various measures of alliance performances (revenues growth, competitive position, customer satisfaction, operations improvement, product improvement, new product development) were also separately investigated.

Obtaining higher than market returns is a difficult goal to achieve, especially in times of turbulence such as the COVID-19 crisis, which tested the resilience of many models and algorithms. We used a Hidden Markov Models (HMM) methodology based on monthly data (DAX returns, VSTOXX index Germany’s industrial production and Germany’s annual inflation rate) to calibrate a trading strategy in order to obtain higher returns than a buy-and-hold strategy for the DAX index., following Talla (2013) and Nguyen and Nguyen (2015). The stock selection was based on 26 stocks from DAX’s composition, which had enough data for this study, aiming to select the 15 best performing. The training period was January 2000 - December 2015, and the out-of-sample January 2016 - August 2021, including the period of high turbulence generated by COVID-19. Fitting the best model revealed that the following regimes are the most suitable: two regimes for DAX returns, two regimes for VSTOXX and three regimes for the inflation rate and for the industrial production, while the posterior transition probabilities were event-depending on the training sample. Furthermore, portfolios built using HMM strategy outperformed the DAX index for the out-of-sample period, both in terms of annualized returns and risk-adjusted returns. The results were in line with expectations and what other researchers like Talla (2013), Nguyen and Nguyen (2015) and Varenius (2020) found out. We managed to highlight that a strategy calibrated based on HMM methodology works well even in periods of extreme volatility such as the one generated in 2020 by COVID-19 pandemic.

Diversity amongst the workforce within central Europe has experienced some form of evolution. This occurrence will incessantly manifest even further in the not-too-distant future. As a result, citizen-dominated societies are gradually tilting towards an increasingly diverse and minority population, broadly of African and Asian descent. Again, demographers suggest the influx of women, minorities, people of different ethnic backgrounds, aging workers, and people with alternative lifestyles within the European employment space, just as the various organizations and schools are filled with these groups. Studies on organizational diversity abound, however, findings from past research on diversity and performance relationships have been equivocal. Thus, the main objective of this study is to assess the mediating role of commitment and job satisfaction in the relationship between diversity and performance. Results from 237 samples drawn from the Czech Republic, Europe and analyzed through partial least square structural equation modelling (PLS-SEM) suggest that diversity does not have a significant relationship with competency-based performance. However, both commitment and job satisfaction play notable roles in the relationship between diversity and competency-based performance. Given these results, we discuss the theoretical and managerial implications.

With the emergence of the gaming industry as the most empowering form of entertainment, video game online communities have become a refuge for many users who are looking to fulfil specific needs, leading them to participate in creating their own experiences. Drawing upon the uses and gratifications theory, this research aims to understand the motivations behind consumer engagement in value co-creation within digital game distribution services (exp. Steam), and how it affects loyalty. To the extent of the author’s knowledge, little research has addressed this question within the gaming industry. We conducted an online survey administered to video game platforms users, through which 195 valid answers were collected. Findings suggest that hedonic along with personal and social motivations have positive influence on user’s engagement to co-create value, which in return increases their loyalty behavior.

The purpose of this paper is to offer a critical understanding of the motivations and benefits of social media usage by small and medium financial enterprises with an empirical study from an emerging economy such as Ghana. Based on previous studies, the current study hypothesizes that customer-firm relationship, financial expectation, firm’s visibility and growth, and market share expectation drive social media usage intensity in the financial industry. Quantitative data was gathered from management and staff of SMEs, specifically, financial institution outlets (having social media channels i.e., Facebook, Instagram, YouTube, LinkedIn, etc.) was used to investigate the proposed conceptual framework. Using structural Equation Modelling, the research showed that customer-firm relationship, financial expectation, firm’s visibility and growth, and market share expectation are positively associated with social media usage intensity within the financial sector. Moreover, it was discovered that financial firms that offer physical products only were equally employing social media networks for marketing communication purposes based on cost-effective motives. At the same time, we found that SMEs are more likely to consider ‘market share expectation’ as a key motivation for social media adoption by the financial industry. The findings from this study have provided some solutions to potential research issues specific to strategic management practices. Limitations and future research directions are discussed in the concluding remarks.
