“…Population error measurement reveals that root mean squared error of approximation = 0.076, close to 0.05, lower bound of 90% Confident interval = 0.071, close to 0.05, upper bound of 90% = 0.081, less than 0.1 and pclose = 0.000, less than the suggested threshold of 0.05 (see Table 5). Thus, the population error indices of the SEM model used in this work (see Figure 2) are regarded as having a good fit (Comulada, 2021). On the other hand, the evaluation of baseline comparison reveals that the values of the Tucker–Lewis index (TLI) and comparative fit index (CFI) are both near to or equal to 1.…”

Purpose The purpose of this study is to empirically examine the effect of marketing modification on business performance from the perspective of marketing capabilities theory. Design/methodology/approach This study employed a survey method to collect data from 225 food processing small- and medium-sized enterprises (SMEs) on the Ghana Enterprise Agency (GEA) registered list in the Eastern Region of Ghana. The effect of marketing modification on the performance of SMEs in the food processing industry was evaluated using a structural equation modeling (SEM) – path analysis. Findings According to the study’s findings, marketing modification has a positive and significant impact on the financial performance (FP), customer performance (CP), internal business process performance (IBPP) and learning and growth performance (LGP) of Ghanaian SMEs engaged in food processing. The results of this study also demonstrated the importance of marketing modification determinants, such as marketing resources (MR), cross-functional and interenterprise collaboration (CFIEC), architectural marketing capability (AMC) and marketing strategy decision implementation (MSDI), in achieving food processing SME performance in Ghana. Research limitations/implications This current research has its limitation, even though its importance has been mentioned earlier. First, the study can be improved by expanding the sample size through the inclusion of other SMEs from other industries since it is industry specific (i.e. food processing SME). Second, this current study was conducted in Ghana. To compare results, the current study may be replicated in other emerging countries. Third, future research studies may consider how business environmental factors such as technological change (e.g. use of artificial intelligence and machine learning) moderate the relationship between marketing modification and SME performance. Practical implications The outcomes of this research study are anticipated to give profitable implications to both academicians and practitioners. For the academic aspect, this study provides an important contribution to marketing modification and performance literature by examining the impact of innovative marketing on the performance of food processing SMEs in Ghana. For practitioners, this study indicates that food processing SME owners/managers must focus on marketing modification to develop their performance. The increase in marketing modification application through marketing capabilities such as MR and CFIEC will enable owners/managers to achieve performance targets. Social implications The application of marketing modification among food processing SMEs in Ghana will contribute greatly to their profitability, survival and growth. The growth and survival of food processing SMEs (not limited to food processing SMEs) in Ghana will help in the control of unemployment, which is a major social issue in Ghana. Originality/value The study’s findings provide solid support for the marketing capabilities theory. This study also supports the notion that food processing SMEs should perceive marketing modification and its determinants (i.e. MR, CFIEC, AMC and MSDI) as a critical strategic capacity to enhance their performance (i.e. FP, CF, IBPP and LGP). In terms of contribution, this study adds to the body of knowledge already available on marketing modification and business performance, particularly in the setting of an emerging economy.

“…Significance of direct and indirect effect was determined with the lower and upper limits of 95% confidence interval (CI) bootstrap sample of 5000 (Chung et al, 2022; Lv, Wu, et al, 2021). Model fit was evaluated by goodness of fit indices which included χ 2 /df (acceptable fit < 3, the comparative fit index [CFI], acceptable fit ≥ 0.90) and the root mean square error of approximation (RMSEA, acceptable fit ≤ 0.08) (Comulada, 2021). Figure 1 the model presents the direct and indirect effect that we adopted in this current study.…”

Aim: To explore the effects of disability, depressive, anxiety and stress symptoms on patients' and their partners' quality of life (QoL) using the actor-partner interdependence model (APIM). Design:A cross-sectional study using actor-partner interdependence model. Methods:We recruited 183 dyads of stroke survivors and their family caregivers in Indonesia. The World Health Organization Disability Assessment (WHODAS 2.0), Depression, Anxiety and Stress (DASS-42) and Rand Short Form Health Survey (SF-36) were used to measure disability, depressive, anxiety and stress symptoms and QoL of stroke survivors and family caregivers. The actor-partner interdependence model was tested using multilevel modelling. The actor-partner interdependence mediation model (APIMeM) was applied to estimate the direct and indirect effect.Results: Disability had actor effects on stroke survivor's overall QoL and partner effect on family caregiver's overall QoL. More severe disability of stroke survivors was associated with a lower overall QoL of their own and that of family caregiver's overall QoL. Depressive symptoms of stroke survivors had actor effects on stroke survivors' overall QoL and partner effects on family caregivers' overall QoL. Actor and partner effects also exist on family caregiver's depression symptoms to their own overall QoL and stroke survivor's overall QoL. Moreover, higher anxiety symptoms were associated with lower levels of their own and partner's overall QoL in both stroke survivors and family caregivers. Stroke survivor's stress symptoms also negatively associated with their own and family caregiver's overall QoL. However, a family caregiver's stress without a partner effects on stroke survivor's overall QoL. The APIMeM analysis showed that disability of stroke survivors directly decreased their own overall, physical (PCS) and mental QoL (MCS). Also, disability mediated by stroke survivor's depression, anxiety and stress symptoms decreased both stroke survivor's and family caregiver's physical (PCS) and mental QoL (MCS). Conclusion:The findings suggest that stroke survivors and family caregivers may influence each other during the caregiving process and social life. The disability of stroke survivors, and the depression, anxiety and stress symptoms of stroke survivors and

“…Once the temporal association between severe sleep apnea and CHD had been established, mediation models were constructed to examine whether the association between severe sleep apnea and CHD was respectively mediated by metabolic factors and CRP [15]. The causal steps approach based on the inf luential work proposed by Baron and Kenny was conducted to investigate the effect of severe sleep apnea on the incidence of CHD partially mediated through metabolic factors and CRP.…”

Background It is unclear whether metabolic and inflammatory factors mediate the association between severe sleep apnea and coronary heart disease (CHD) in observational studies based on the large-scale population. This study aims to assess the association between severe sleep apnea and CHD and to explore the extent to which this association is mediated by metabolic factors and C-reactive protein (CRP). Methods In UK Biobank, 213 442 CHD-free (mean age: 55.00) adults were followed up for 15 years to detect incident CHD. Metabolic factors included hyperglycemia, hypertension, dyslipidemia, hypertriglyceridemia, and hyperuricemia. A higher CRP concentration level was defined as a cutoff point of >3.0 mg/l. Data were analyzed using Cox proportional hazards models and the generalized structural equation model. Results During follow-up, 9278 participants developed incident CHD (4.3%). The multi-adjusted hazard ratio and 95% confidence interval of CHD related to severe sleep apnea were 1.76 (1.44–2.15). In the mediation analysis, the strongest indirect association was for dyslipidemia, accounting for 20.8% of the association between severe sleep apnea and CHD (β = 0.22, 95% confidence interval = 0.16–0.28), followed by hypertriglyceridemia (12.3%). The proportion of mediation increased to 29.1% when CRP was added to the metabolic mediators. Conclusions Severe sleep apnea was associated with an increased risk of CHD. Lipid factors might play an essential role in the severe sleep apnea–CHD relationship. CRP increased the magnitude of mediation effects of overall metabolic factors.
