Working memory (WM) has been extensively studied as a cognitive factor influencing second language acquisition (SLA), but many studies treat it as a static, trait-like capacity. This approach provides limited insight into how WM works across different stages of development, proficiency levels, and learning contexts. This article combines theoretical and empirical research on working memory in SLA from a dynamic and developmental perspective, analyzing how the influence of WM varies over time and interacts with other cognitive and contextual factors. Referencing Baddeley's multicomponent model, complex dynamic systems theory, and longitudinal research, this article examines evidence regarding the role of WM in various language domains, including vocabulary learning, grammar processing, and language production. It also investigates how WM works differently at various proficiency levels and developmental periods, from childhood to adulthood. Evidence suggests that WM plays a very strong role in the early stages of learning when processing is effortful and controlled, but becomes less central as linguistic knowledge becomes automated. The relationship between WM and SLA appears to be bidirectional, with sustained language learning contributing to the development of specific WM components, particularly executive control. The influence of WM varies significantly based on task characteristics, teaching context, and learner profiles. Understanding WM as a dynamic resource rather than a fixed constraint has important pedagogical implications. Instructions that manage cognitive load, provide support, and encourage metacognitive awareness can help learners with diverse cognitive profiles. A developmental approach in WM research requires longitudinal designs and task-aligned methodologies to capture changes over time, thereby advancing theory and practice in SLA.

Background: Anxiety in postpartum mothers is a psychological problem that can negatively impact maternal mental health, marital relationships, and the lactation process. This psychological disorder can inhibit the production and let-down of breast milk, which, if not addressed promptly, can lead to physical complications such as breast engorgement or mastitis, as well as hinder the fulfillment of the infant's nutritional needs. Objective: This study aimed to determine the relationship between anxiety levels and delayed breast milk let-down in postpartum mothers at Prof. Dr. R.D. Kandou General Hospital Manado. Methods: This research is an analytical survey with a cross-sectional design. The sample consisted of 30 postpartum mothers selected using non-probability sampling. Research instruments included questionnaires and interviews, with data analysis using the chi-square test. Results: The majority of respondents experienced moderate anxiety (60.0%) and had non-smooth breast milk let-down (53.3%). Statistical test results showed a p-value = 0.030, indicating a significant relationship between anxiety levels and delayed breast milk let-down. Conclusion: High anxiety levels in postpartum mothers contribute to delayed breast milk let-down. Psychological support for postpartum mothers is needed to maintain the smoothness of the breastfeeding process.

This study aims to elaborate on the mechanism of product design, word of mouth (WOM), price perception, and product quality on purchase decisions, with brand image serving as a mediating variable. The research focuses on consumers of Ogel-Ogel, a traditional snack product from Pemalang. Utilizing a quantitative descriptive method, data were gathered from 100 respondents through purposive and accidental sampling techniques. Data analysis employed path analysis and the Sobel test to measure the strength of the mediation effect. The results reveal that, partially, all independent variables and brand image exert a positive and significant influence on purchase decisions. The most crucial finding indicates that brand image acts as an effective mediating bridge, reinforcing the transformation of physical product attributes and social recommendations into actual purchasing actions. This underscores that for MSMEs in the culinary sector, visual uniqueness and quality are insufficient without consistent brand reputation management. This research provides strategic contributions for local product managers in integrating traditional marketing elements with brand equity strengthening to navigate an increasingly competitive market.

Cilacap Regency in Central Java Province is recognized as an important contributor to national food production due to its extensive agricultural land and reliance on technical irrigation systems. The performance of irrigation networks, particularly secondary channels in the Serayu Irrigation Area (DI), is essential in regulating water levels to support agricultural activities in Sampang and Karangasem Villages. Variations in rainfall and field conditions often create water level differences that disrupt irrigation distribution, reducing water flow efficiency to rice fields and lowering productivity, especially during the dry season. This study aims to design secondary irrigation channels capable of maintaining stable water levels based on irrigation requirements. The research applies a descriptive quantitative method using rainfall data from BMKG, along with land area and elevation data interpreted from Google Earth imagery in 2025. The data were analyzed using probability and Thiessen polygon methods to estimate design rainfall, determine water availability, calculate irrigation demand, and plan channel dimensions. The analysis shows that Secondary Channel BGS 4.B serves an irrigation area of 103.57 hectares with a planned discharge capacity of 0.0343 m³/s. The channel design includes a base width of 0.65 meters and a water depth of 0.65 meters, with water surface elevations of 14.27 meters upstream and 13.15 meters downstream. Evaluation using a 10-year rainfall return period of 151.677 mm shows the channel can convey discharge effectively while maintaining water levels below the embankment, ensuring reliable irrigation distribution.

This study is motivated by the rapid advancement of digital marketing and the increasing influence of psychological factors in shaping consumer behaviour, particularly among Generation Z, who are highly exposed to social media and global trends in imported skincare products. This phenomenon suggests that purchase decisions are not solely driven by digital marketing strategies but are also significantly influenced by emotional drivers such as Fear of Missing Out (FoMO). Accordingly, this study aims to analyse the effects of affiliate marketing, WhatsApp status, celebrity advertising, and FoMO on the purchase intention of Generation Z consumers in Tangerang City. Specifically, the study pursues five objectives: (1) to examine the effect of affiliate marketing on purchase intention; (2) to analyse the influence of WhatsApp status on purchase intention; (3) to investigate the impact of celebrity advertising on purchase intention; (4) to evaluate the effect of FoMO on purchase intention; and (5) to assess the simultaneous effects of all independent variables on purchase intention. This study adopts a quantitative approach using a survey method, with data collected through structured questionnaires administered to 250 respondents selected via accidental sampling. Data were analysed using multiple linear regression with the aid of SPSS software to examine the relationships among variables. The findings reveal that all independent variables exert a positive and statistically significant influence on purchase intention, with FoMO emerging as the most dominant predictor. These results underscore the greater role of psychological factors relative to digital marketing strategies in driving purchase intention among Generation Z consumers.The contribution of this study lies in integrating digital marketing strategies and psychological factors into a single empirical model, while also highlighting the growing importance of interpersonal digital communication, such as WhatsApp, in contemporary marketing contexts. From a practical perspective, the findings provide managerial implications for businesses to design marketing strategies that are not only informative but also capable of creating urgency and fostering emotional engagement among consumers.

The hyper-connected work era has fundamentally blurred the temporal and psychological boundaries between professional and personal spheres, triggering a productivity paradox phenomenon where increased digital connectivity is inversely proportional to long-term cognitive efficiency. Consequently, this research aims to explore deeply and comprehensively the critical roles of cognitive resilience and digital wellbeing strategies as vital preventive mechanisms against the rising risk of burnout resulting from cumulative cognitive fatigue. Employing a qualitative approach with a rigorous literature review design, this study synthesizes extensive secondary literature retrieved from accredited academic databases and global policy reports within the last five years to analyze current trends and theoretical frameworks. The in-depth analysis reveals that cognitive resilience, significantly bolstered by metacognitive digital literacy, functions as an adaptive shield against the mounting pressures of information overload and attention fragmentation. Furthermore, the findings emphatically confirm that sustainable productivity is not achieved through borderless connectivity, but rather necessitates disciplined cognitive energy management and the strict implementation of "right to disconnect" protocols. Concluding the study, it is strongly recommended that organizations integrate comprehensive digital wellbeing policies into their work culture architecture to safeguard long-term employee performance and ensure organizational sustainability amidst the challenges of the attention economy.
