Prolonged social media use is not fundamentally problematic in a Hungarian representative study

Abstract Excessive time spent using social media is often considered a core characteristic of technology-related addictions; however, there is growing evidence that prolonged use may be only weakly associated with symptoms of problematic use. Studies on the divergent associations of psychological factors with prolonged and problematic social media use are still scarce, particularly in adult, representative samples. Based on self-report data, this study aims to address this gap by investigating possible divergent associations of prolonged and problematic social media use among active and passive use, and indicators of psychological distress in a nationally representative sample of adults. A hybrid data collection procedure was employed, including offline and online panelists. The sample comprised 807 Hungarian adults (53.41% women, M age = 46.61 years, SD  = 16.58). A structural equation model (SEM) was constructed. Both active and passive use predicted more time spent on social media, while problematic social media use symptom severity was predicted by active use, social comparison, and psychological distress. The explanatory power of these factors was notable in problematic social media use (58%) and modest for time spent on social media (16%). These findings provide further evidence that prolonged and problematic social media use may be different in their qualitative characteristics.

Optimizing agricultural production for economic sustainability of sunflower across climatic zones

Abstract Increasing global food demand and climate variability are placing unprecedented pressure on agricultural systems, necessitating a shift from generalized farming practices to site-specific precision management. However, a lack of long-term economic optimization studies for sunflower production in Türkiye limits the adoption of climate-resilient strategies. This study addresses this gap by utilizing the Decision Support System for Agrotechnology Transfer (DSSAT) to evaluate 1000 management scenarios across three distinct climatic regions (Edirne, Adana, and Konya) using 30 years of daily weather data (1991–2020). The analysis identified optimal planting dates, irrigation thresholds, and nitrogen rates to maximize economic profitability. Results indicated that optimal planting dates were March 20 for Edirne, April 30 for Adana, and May 10 for Konya. The economic optimum for irrigation start threshold was identified as 40% of Available Water Content (AWC) for Edirne and Adana, and 50% AWC for Konya, highlighting the value of managed deficit irrigation. Regarding fertilization, optimum profitability was achieved at 250 kg N/ha for Edirne and 300 kg N/ha for Adana and Konya. These optimized strategies significantly enhanced water productivity and ensured positive economic returns. The findings demonstrate the effectiveness of DSSAT in defining site-specific management protocols that reconcile economic viability with resource sustainability.
