“…Moreover, results were consistent with a mediation model - the indirect effect of age on the ERN via social anxiety symptoms was significant, effect = −.03, 95%CI[−.09, −.01], suggesting that developmental increases in social anxiety symptoms as reported by parents underlies, in part, the developmental increase in the ERN. To test specificity of the model, the mediator and outcome were reversed (i.e., social anxiety symptoms were entered as the outcome variable and the ERN was entered as the mediator; Agler & De Boeck, 2017). Results suggested that the indirect path did not reach significance, effect = .005, 95%CI[−.02, .09].…”

Anxiety is the most common form of psychopathology and tends to begin early in the course of development. Given this, there is great interest in identifying developmental changes in neural systems that may delineate healthy versus anxious trajectories. A substantial amount of work has focused on the error-related negativity as a neural marker of anxiety. The ERN is a negative deflection in the event-related potential that occurs when individuals make mistakes and is increased in anxious individuals. A separate body of work has focused on normative developmental changes in the ERN - demonstrating an age-related increase in the ERN that occurs across childhood and adolescence. In the current study, we examine the ERN in relation to specific phenotypic expressions of anxiety during a core risk period in a sample of females (N = 220) ranging from 8 to 14 years old. Results from the current study suggest that error-related brain activity is related to both parent and child report of social anxiety symptoms, even when controlling for all other symptom scales. Additionally, mediation models suggest that the normative developmental increase observed in the ERN is partially mediated by increases in social anxiety symptoms. The current results are novel insofar as they identify a specific phenotypic expression of anxiety that underlies developmental increases in this neural biomarker.

OBJECTIVES: Poor diet due to poor oral health was proposed as a potential mediator of the association between poor oral health and frailty. This study explores the cross-sectional associations between poor oral health, poor diet, and frailty in Canadian adults, aged 45 to 85 years, and then tests whether the expected oral health-frailty association is changed by taking into account the pathway through poor diet. DESIGN: Cross-sectional study. SETTING: The baseline wave of the Canadian Longitudinal Study on Aging, a nationally representative population study. PARTICIPANTS: Data from 28 738 community-dwelling participants, aged 45 to 85 years. MEASUREMENTS: We characterized poor oral health (cumulative count of 24 items of oral health problems), poor diet (scale of poor food consumption from 7 healthy foods groups), and frailty (cumulative frailty index of 76 items). Regression-based path analyses were used to investigate associations between poor oral health, poor diet, and frailty, adjusted for age group, sex, income, smoking, living alone, education, physical activity, social support, and dental visit. RESULTS: Poorer oral health was associated with low income, smoking, low physical activity, low social support, and no dental visit. There were associations between poorer oral health and poorer diet (effect size β adjusted = .40; 95% confidence interval [CI] = .20-.61) and between poorer oral health and increased frailty (β adjusted = .85; 95% CI = .68-1.02). The indirect effect through the path of poor diet was approximately 0.01 (95% CI = 0.01-0.02) (ie, explaining 1% of the effect of poor oral health on frailty). CONCLUSIONS: Poor oral health was associated with poor diet and frailty. Each additional oral health problem was associated with an increase of approximately 1 frailty index point, even after full adjustment for poor diet. The indirect effect of poor oral health through poor diet was modest. Though poor oral health was associated with poorer diet quality, a more direct effect of poor oral health on increasing frailty may be indicated. J Am Geriatr Soc 68:959-966, 2020.

“…The process of examination highlighted the mediation analysis of microfinancing on the effect of access to finance on the growth of microenterprises. The objective of the mediation analysis was to seek a deeper understanding of the direct and indirect effects of the independent variable (IV) on the dependent variable (DV) when there is a mediator variable (Agler & De Boeck, 2017). Since the study is about the impact on growth, the process was expected to change the level of the effect as a result of the mediating variable; thus, the total effect of IV on DV in a normal regression may be found insignificant when mediation analysis is applied.…”

The mediating effect of microfinancing on access to finance and growth of microenterprises: evidence from the Philippines

Undoubtedly, microenterprises play a critical role in the development of the economy. Comprising a dominant share in the industry, microenterprises help to alleviate poverty and unemployment. However, the growth of microenterprises remains a global challenge. A number of scholars have attributed the growth of microenterprises to accessibility of finance; however, microfinancing is equally significant in the initiative of owners to expand. This study aims to examine how microfinancing mediates the effect of access to finance on the growth of microenterprises. A survey result from a dataset of 582 microenterprises from the Philippines was used for correlation, regression, and mediation analyses. The results suggest that the impact of access to finance on the growth of microenterprises is heightened when microfinancing is maximized. However, the owners' preferences toward internal financing limit the ability to expand. Thus, the issue of stagnation is a result of the owners' isolation to external financing. The results highlight the need for a more holistic approach to enterprise growth than merely facilitating access to finance. The study recommends aspects such as literacy and competitiveness as factors other than access to capital as enablers of growth. The results may challenge policymakers to enhance the existing policy frameworks further and provide more skills-enhanced income opportunities. Further, an experimental research using an intervention may help discover how to overcome stagnancy of micro and small firms.
