“…The low R -squared of 0.341 reported in the LPM in Table 4 was because the study focused on the human decision of whether to use formal financial services or not. This is consistent with Ozili (2023b) who posited that any field that attempts to predict human behaviour typically has R -squared values lower than 50%.…”

The study investigated the determinants of financial inclusion in selected African countries. Researchers have found an extraordinarily strong positive association between social inclusion and financial inclusion; financial inclusion is the key to eradicating poverty and social exclusion as it presents an opportunity for people to benefit from financial services. A single data set was formed by combining four samples from the Democratic Republic of Congo, Eswatini, Kenya and South Africa. Data were obtained from surveys done by FinScope. FinScope Consumer Survey is a probability survey with an end-user focus (individual or household) on financial services and products. The FinScope Consumer Survey, done by the FinMark Trust, is uniquely aimed at increasing understanding of the informal financial product/service market. Probit regression models were estimated to find significant factors influencing financial inclusion in selected African countries. The linear probability model was used for the robustness check. The study found that age, education, marital status, bank branch accessibility, location, internet, salary, income, proof of residence, social networks, financial advice, gender and connectivity were significant in influencing financial inclusion. Governments must implement policies that enhance financial inclusion, in particular, ethnic groups, small communities and minorities. These policies will also lead to the reduction of poverty and the attainment of the UN Sustainable Development Goals.

“…The two models reported in Table 3 explained between 43 and 50% of the variance in performance quality scores. Nevertheless, we prefer not to further comment on R 2 values, as their interpretation is quite controversial (i.e., Ozili, 2022 ), nor is a comparison between the two models reported in Table 3 meaningful, as they consider participants’ state anxiety measured at two distinct timepoints.…”

The effects of anxiety on practice behaviors and performance quality in expert pianists

IntroductionDuring their career, musicians need to undergo intense periods of training to master musical instruments and become accomplished artists. Dysfunctional practice behaviors and anxiety are often mentioned among the possible risk factors for playing-related injuries in musicians. However, the mechanism through which these might lead to the onset of these injuries is still unclear. The present study aims at overcoming this limitation by investigating the relationship between quantitative measurements of anxiety, practice behaviors and music performance quality.MethodsThe experiment consisted in monitoring practice behaviors in 30 pianists practicing a short musical task.ResultsMost self-report anxiety measurements were positively correlated with practice time, especially those collected right before the practice sessions. Similar correlations were identified between anxiety and the number of repetitions of the musical task. Physiological markers of anxiety were only weakly related to practice behaviors. Subsequent analyses showed that high levels of anxiety were associated with poor quality of music performances at baseline. Nevertheless, the interaction between participants’ learning rate and anxiety measures showed no association with performance quality scores. Moreover, anxiety and performance quality co-developed during practice sessions, showing that pianists who improved their playing were also less anxious in the latter part of the experiment.DiscussionThese findings suggest that anxious musicians are likely at higher risk of developing playing-related injuries related to overuse and repetitive strains. Future directions and clinical implications are discussed.

“…The model's in‐sample predictive power was ascertained using the coefficient of determination ( R 2 ) (Hair et al, 2011). Ozili (2023) concluded that R 2 values of 0.02, 0.13, and 0.26 have weak, moderate, and strong predictive power, respectively.…”

This study employs a multimethod approach to examine the factors motivating consumers to interact with brands through live‐streaming platforms and how they affect their hedonic well‐being. The result indicates that exclusively relying on the net effects of the motivating factors could be misleading. It presents an insight into how a mediation effect (psychological engagement) affects the interdependence of the independent variables in achieving hedonic well‐being. Although the structural equation modeling results highlight the significant mediating impact of psychological engagement, the fuzzy‐set qualitative comparative analysis shows that psychological engagement is only a core condition in one configuration (out of the three configurations). That is when two motivational factors (brand awareness and real‐time customer service) act as a substitute, and the others (convenience and consumer–brand relationship quality) are present. Therefore, psychological engagement is indifferent when all motivational factors are present. This study, through the application of a multimethod approach, shows that motivational factors for using live‐streaming are only necessary for escalating consumer well‐being but not sufficient in themselves.
