Inadequate access to antenatal care (ANC) services is a public health problem that is promoting maternal and child mortality in many developing countries. In Niger, utilization of ANC services is a fundamental requirement for achieving some targets in the Sustainable Development Goals (SDGs). The study analyzed the impact of maternal education on the intensity and timeliness of ANC utilization. The data were from the 2021 Malaria Indicator Survey (MIS) and were analyzed with exponential mean treatment effects model. The results showed that 68.66% of the women attended ANC three or four times, while 48.58% did not visit health centres for up to four times. Only 27.09% attended ANC during the first trimester of their pregnancies. The exponential mean model showed that the expected mean of ANC visits significantly increased with women’s age, education levels, urban residence, listening to radio, wealth index and use of Fasidar medication. Moreover, the expected mean of pregnancy month before seeking ANC declined with women’s age, education levels, and wealth index. The average treatment effects (ATE) and average treatment effects on the treated (ATET) were positive for ANC utilization intensity and negative for utilization timeliness. It was recommended that efforts to promote ANC utilization in Niger should promote maternal education through media programmes, manage malaria and create awareness on the minimum required ANC visits for optimum management of maternal and child’s health.

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.

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.
