Abstract

The COVID-19 pandemic has brought significant socioeconomic problems to many developing countries. In Mozambique, the impacts of the pandemic were felt in different spheres of households’ livelihoods. This study contributes to the existing body of knowledge by analyzing the effects of coping strategies and other factors on households’ dietary diversity scores (HDDS). The data were collected in two non-longitudinal waves in 2021 and 2022 from 3975 households by the Food and Agriculture Organization (FAO). The instrumental Poisson regression model was used for data analysis. The results showed that across the two periods, cereals were mostly consumed (96.93%), while meats (15.75%), milk and dairy (13.99%), and eggs (9.16%) were the least consumed. There was an increment in the proportion of households that consumed between zero and four food groups. Furthermore, there were declines in the utilization of coping strategies, while depletion of savings (50.62%) and credit (45.21%) were mostly used. The instrumental variable Poisson regression results revealed that expected HDDS decreased significantly (p<0.05) with sold animals, eating elsewhere, consumption of seed stock, decreased agricultural input expenditures, and emergency begging, whereas illegal activities increased it. In addition, household incomes, crop farming, and being younger than 35 years significantly increased (p<0.05) the expected HDDS, while all regions except Gaza had significantly higher expected HDDS than Cabo Delgado. It was concluded that adopted coping mechanisms could not offset households’ food problems during the pandemic, although some regional differences existed. Therefore, initiatives to promote human nutrition in Mozambique should enhance households’ resilience to income shocks through region-specific income-promoting activities.

Abstract

Public hospitals in Ghana face challenges such as limited resources and inconsistent care delivery, which impact patient satisfaction and loyalty. In this context, enhancing service quality is crucial for retaining patients and improving healthcare outcomes. This study investigates the role of service quality in shaping patient loyalty and explores patient satisfaction as a mediator in selected public hospitals in Ghana using the SERVQUAL model. A survey was conducted among 200 outpatients from five public health facilities in Kumasi, Ghana, between January and February 25, 2024. A quantitative methodology was applied to evaluate how patients' perceptions of service quality influence their loyalty toward public healthcare providers. In order to analyze the data, SPSS and the smart partial least square (PLS) software version 3.0 were used for structural equation modeling (SEM). The findings revealed that communication, the physical environment, and responsiveness significantly affect patient loyalty, whereas factors such as privacy, safety, and a customer-friendly atmosphere do not. Additionally, this study confirmed that patient satisfaction mediates the relationship between service quality and patient loyalty, underscoring the importance of service quality in enhancing both satisfaction and loyalty in health care. Based on these insights, this study recommends that health care institutions improve their service quality to strengthen public healthcare systems. The significance of this paper extends beyond regression analysis, as it also addresses the delayed effects of service quality on patient loyalty, considering both direct and indirect influences in the regression models.

Abstract

This study investigates the challenges construction sector companies face due to market disruptions and the lack of innovation, with a specific focus on PT Wijaya Karya (WIKA), a leading Indonesian construction firm. Drawing on Kodak's failure as a cautionary example of the risks of neglecting technological advancements, the research underscores the critical need for companies to remain adaptable and ready to innovate to address evolving customer demands. In response to a significant financial loss of IDR 7.13 trillion in 2023, WIKA implemented cost-saving measures, including workforce restructuring and halting recruitment. Despite these setbacks, the company showcased resilience by initiating innovative projects, such as electric motorcycles and precast concrete technologies, contributing to its recovery. The research emphasizes WIKA's initiatives to cultivate employee readiness for change through programs like Wikasatrian and technology skills development. Utilizing a descriptive quantitative approach, the study surveyed 233 managers and directors from government-owned construction firms (BUMN), employing instruments to measure readiness for change, psychological capital, and job security. Data analysis using Structural Equation Modeling (SEM) confirmed that psychological capital plays a critical mediating role between job security and readiness to change. Findings reveal that job security significantly impacts readiness to change, with psychological capital acting as a strong mediator. The study highlights the importance of investing in psychological resources to foster adaptability, particularly in sectors undergoing technological and organizational transformations. The model demonstrated strong validity, with fit indices including GFI (0.90), CFI (0.98), TLI (0.97), NFI (0.97), and RMSEA (0.09), affirming its robustness and providing valuable insights into the public construction sector, an area often underexplored in previous research.

Abstract

This study analyzes the effect of the 2024 general election on the stock prices of companies affiliated with presidential and vice presidential candidate pairs in Indonesia. The methodology used in this study is an event study to measure abnormal returns before and after an election. The sample includes companies listed on the IDX, with as many as 34 companies listed based on connection politics. The research period comprises 40 estimation periods and 20 event periods. The statistical tools used for hypothesis testing were the t-test, paired sample t-test, and Wilcoxon signed-rank test. This study found that election-related information does not significantly impact average abnormal returns (AAR) before and after. However, the event study results show that political connections between companies with presidential and vice presidential candidates affect market reactions to new information during the event period. This study is essential for investors and capital market practitioners when formulating investment decision-making strategies during the general election period. These results are expected to serve as a reference for further studies on the influence of politics on the capital market in Indonesia.

Abstract

This study examines the influence of intrinsic motivation and parenting style on personality stability among students at the Defense University. Personality stability is a crucial component in shaping resilient, consistent, and adaptive character, especially in a military educational environment that demands a high level of discipline. Intrinsic motivation is defined as the internal drive to engage in activities perceived as meaningful, enjoyable, and challenging. Meanwhile, parenting style, whether delivered by regimental caregivers or peer mentors (senior cadets), plays a vital role in shaping the attitudes and behaviors of students. Emotional stability reflects an individual's ability to process and express their emotions in a manner consistent with their developmental stage. This research employed a quantitative approach using a multiple linear regression design. The population consisted of 250 students, with 153 active students selected as the sample. Data were collected using a Likert-scale questionnaire that measured the variables of intrinsic motivation, parenting style, and personality stability. The findings revealed that intrinsic motivation and parenting style simultaneously significantly influence personality stability, with a standardized coefficient of 0.83 and a t-value of 18.59. Intrinsic motivation alone had a significant effect, with a coefficient of 0.71 and a t-value of 12.29, whereas parenting style had a significant effect, with a coefficient of 0.18 and a t-value of 3.23. These results reinforce the importance of autonomy, competence, and relatedness, and support the two-dimensional parenting theory. The study also highlights the significant roles of permissive and authoritarian parenting styles within the military university context. This research provides theoretical contributions to the development of personality and motivation in higher education, particularly in military academic environments. The findings serve as a basis for institutions to design learning strategies and character-building programs that promote intrinsic motivation and support the development of a stable personality. This study also provides a foundation for future psychosocial interventions and initiatives aimed at enhancing student character.

Abstract

Inadequate access to antenatal care (ANC) is a public health problem promoting maternal and child mortality in many developing countries. In Niger, the utilization of ANC is a requirement for achieving some of the targets of the third Sustainable Development Goal (SDG3). This study analyzed the impact of maternal education on the intensity and timeliness of ANC use. The data were drawn from the 2021 Malaria Indicator Survey (MIS). Data were analyzed using an exponential mean model, and regression adjustment Average Treatment Effect (ATE)/ Average Treatment Effect on the Treated (ATET) estimators. The results showed that 68.66% of the women attended ANC three or four times, whereas 48.58% did not visit health centers up to four times. Only 27.09% of pregnant women attended ANC during the first trimester. The results from Poisson regression showed that ANC visits significantly increased with women’s age, education levels, urban residence, listening to radio, wealth index, and use of Fasidar medication. Moreover, the first ANC pregnancy month was associated with the women’s age, education level, and wealth index. The ATEs and ATETs were positive for ANC use intensity and negative for use timeliness, respectively. It was recommended that efforts to promote ANC use in Niger should, among others, promote maternal education through media programs.

Abstract

The rapid growth of digital payments in Southeast Asia, particularly Indonesia, has transformed financial behaviors, yet significant adoption and usage gaps remain among mid-to-late adulthood consumers. This study investigates the determinants of e-wallet continuance usage and loyalty within this mid-to-late adulthood segment in Indonesia, here referring to individuals aged 40 years and above, a demographic increasingly important to the nation’s digital economy. Drawing on Expectation Confirmation Theory and supported by insights from technology adoption and institutional perspectives, the research examines the influence of government support, social influence, and network externalities on continuance usage, and the role of continuance usage in shaping loyalty. Using a quantitative, cross-sectional design, data were collected from 223 e-wallet users within the targeted age segment and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings show that government support and social influence positively predict continuance usage, underscoring the importance of institutional legitimacy and interpersonal cues in reinforcing digital payment engagement among mid-to-late adulthood consumers. In contrast, network externalities do not significantly influence continuance usage, suggesting that market-wide adoption cues play a limited role for this demographic. The results also confirm that continuance usage strongly predicts loyalty, highlighting the importance of sustained user experience in fostering long-term commitment to e-wallet platforms. Collectively, these insights offer theoretical contributions to fintech continuance literature and practical implications for strengthening digital inclusion and user retention among older consumers.

Abstract

This study aims to analyze the effect of work motivation on employee engagement with integrity as a mediating variable, as well as to examine its implications for the development of an anti-corruption culture among permanent employees of PT. KAI. The study employs a quantitative approach using a survey method. Data were collected through questionnaires distributed to 224 permanent KAI employees. The data were analyzed using Structural Equation Modeling (SEM) with the assistance of LISREL software. The results indicate that the structural model with integrity as a mediator meets the goodness-of-fit criteria. Work motivation does not have a direct effect on employee engagement, but it requires integrity as an ethical foundation. Furthermore, work motivation has a positive influence on integrity, which in turn strengthens employees’ attachment to their work. However, integrity alone does not have a direct impact on employee engagement and requires the support of motivational and organizational factors. These findings suggest that motivation without integrity may lead to opportunistic behavior. The combination of motivation and integrity fosters stronger, more productive, and ethically grounded employee engagement. Practically, this study highlights the importance of strengthening work motivation framed by integrity to build a sustainable anti-corruption culture within state-owned enterprises.

Abstract

The rapid development of digital technology has significantly transformed consumer behavior in accessing information and making purchasing decisions. Among various platforms, Instagram has emerged as a dominant medium where social media marketing (SMM) strategies are widely employed to reach and influence consumers. However, the effectiveness of SMM is not always straightforward, as its impact on purchase decisions can be strengthened or weakened by other factors, particularly brand awareness. Consumers tend to favor brands they recognize, making brand awareness a critical element in the decision-making process. This study investigates the influence of SMM on purchase decisions with brand awareness as a moderating variable. The population consisted of 1,196 customers of Teman Publikasi – Research Synergy Institute (RSI) within the period of November 2024 to April 2025. Using Krejcie and Morgan’s sampling table, 64 respondents were selected and surveyed with a Likert scale questionnaire. Data were analyzed through multiple linear regression and moderated regression analysis (MRA) to assess both direct and moderating effects. The findings reveal that the five SMM dimensions; entertainment, interaction, trendiness, customization, and word of mouth positively and significantly influence purchase decisions. Furthermore, brand awareness significantly moderates this relationship but in a negative direction, suggesting that higher consumer brand awareness tends to reduce the effectiveness of SMM strategies. This research contributes to the literature by offering empirical evidence on the dual role of brand awareness in digital marketing effectiveness. For practitioners, the study highlights the importance of designing SMM strategies that align with consumer familiarity to avoid diminishing returns.
