This study aims to explore the psychological and emotional adjustment of parents raising children with intellectual disabilities. This qualitative study utilized semi-structured interviews with 26 parents recruited through online platforms. Participants were selected through purposive sampling, ensuring diversity in caregiving experiences. Data collection continued until theoretical saturation was reached, and all interviews were transcribed verbatim. Thematic analysis was conducted using NVivo software to identify key themes related to parental psychological adjustment, coping mechanisms, and social interactions. The results revealed that parents experienced significant emotional distress upon receiving their child’s diagnosis, including grief, denial, and prolonged sadness. Chronic stress was a recurring theme, with concerns over financial burdens, caregiving demands, and uncertainty about their child’s future contributing to heightened anxiety. Coping strategies varied, with some parents relying on social support networks, religious beliefs, and cognitive reframing, while others struggled with emotional exhaustion and isolation. Family relationships were deeply affected, with some parents reporting marital strain and sibling adjustments, whereas others experienced strengthened familial bonds. Social stigma and external judgment further complicated parental adjustment, with many parents becoming active advocates for disability rights and inclusion. Despite the challenges, many parents reported significant personal growth, emotional resilience, and increased psychological strength over time. The psychological and emotional adjustment of parents raising children with intellectual disabilities is a complex process influenced by stress, coping mechanisms, family dynamics, and social factors. While many parents experience significant distress, those with strong support systems and adaptive strategies demonstrate greater resilience. This study highlights the need for targeted support programs, advocacy efforts, and policy interventions to enhance parental well-being and social inclusion.

Knowledge Management (KM) is essential in various sectors, including vocational higher education. A literature review revealed that adopting KM can improve innovation and organizational performance in Higher Education Institutions (HEIs). However, some HEIs in developing countries have yet to realize the benefits of KM, and its implementation still needs improvement. The KM process is affected by several issues, including organizational barriers, knowledge hoarding, a lack of a knowledge-sharing culture, ineffective KM mechanisms, and resistance to technology. Nevertheless, only a few researchers have investigated the antecedents of KM, particularly in vocational higher education institutions. This study aims to evaluate the influence of KM foundation factors on KM processes, innovation, and organizational performance in a vocational HEI, specifically the School of Meteorology, Climatology, and Geophysics (STMKG) in Indonesia. It also examines the mediating effects of KM processes and innovation and provides recommendations for improving STMKG's KM foundation. An explanatory research approach was applied in this study, incorporating both qualitative and quantitative techniques. The results show that Organizational Structure (OS) and Technological Factors (IT) significantly influence KM processes. Innovation (IN) is also a significant mediator between KM processes and Organizational Performance (OP). The practical implication of this study is that it provides recommendations for crucial KM factors based on Importance-Performance Analysis (IPA) for policymakers to improve the foundation of KM at STMKG. Additionally, the study contributes to the academic field by providing insights for further research on KM development in vocational higher education institutions.

The implementation of an effective tax system requires specific conditions, among the most critical being equity and efficiency. Taxation on income must align with the principle of the ability to pay; therefore, governments strive to set tax rates appropriately and impactfully. An disproportionate increase in income tax rates can lead to significant social repercussions on income distribution and public welfare. Consequently, calculating the optimal tax rate to maximize social welfare is deemed essential. This paper models the strategic interaction between taxpayers and the tax authority to achieve an optimal tax rate and identifies the factors influencing this rate. By designing a game among taxpayers, assumed to be uniformly distributed within the interval [0, 1], and evaluating the revenue generation of the tax authority, the paper delves into the game formulation and analyses the results. Findings indicate that the optimal tax rate exhibits an inverse relationship with the assessment rates set by investigating groups. Additionally, under specific conditions, the optimal performance tax rate has been determined to be 18%.

The positive impacts of fiscal policy could be undermined when accompanied by uncertainty. We examined the effect of fiscal policy uncertainty on economic activities in the provinces of Iran. It includes production, investment, unemployment, and economic participation of the active workforce in these provinces, taking into account the effects of economic sanctions imposed on the economy. We employed two types of shocks: fiscal level shock (representing fiscal policy) and its volatility shock (as fiscal policy uncertainty), which derived from a specified fiscal reaction function. We estimated a Panel VAR model using provincial data from 2003 to 2020. The results of the impulse response function indicated that following the impulse in the fiscal policy uncertainty, the response shows an increase in the unemployment rate in the short run, a decrease in the capital investment, and an increase in the inflation rate in the short and medium terms. In the medium and long term, the response indicates a decrease in GDP growth and a reduction in the economic participation rate of the active workforce.

Objective: The tourism sector, a significant component of the global service industry, is vital for a nation’s economic development and income generation. Therefore, it is essential to ascertain the factors influencing the demand for this type of service. The main aim of this study is to examine the impact of exchange rates on tourism demand in Iran. Methods: This study examined the long-term and short-term relationships between Iran’s tourism arrivals and variables such as the exchange rate, political risk, and other factors influencing tourism demand, including inflation, foreign investment, oil revenue, GDP, and population, employing time series data from 1995 to 2024 and the Dynamic ARDL simulation method. Results: The results indicate that political risk significantly detrimentally affects Iran’s tourism demand, whereas the exchange rate has a notable positive influence. Since 2010, when the fourth round of sanctions began, political risk has escalated owing to internal and external conflicts, negatively impacting international tourism demand. Conclusions: The interplay between exchange rate variables and political risk was found to positively influence tourism demand. The increase in the exchange rate decreases the costs of tourism services, and also stimulates creative business endeavors in the tourism industry.
