and social sustainability challenges. Hydroponics allows plants to grow without soil by using
nutrient-rich water to supply the necessary minerals to the plant roots, which enables faster
growth and more fruitful yields.
The inbuilt hydroponic mechanism of the Hydro-Grow Tea Unit easily facilitates the growth of
small plants and fresh herbs for its users. It gives them a regular and continuous supply of greens
and hence motivates healthiness. Whether the outside light conditions are, the integrated LED
grow lights will always let the plants have the kind of light needed for proper development.
Then, the modular plant pods will allow users to tailor their greenery according to seasonal
change or as their taste may be, while an air diffuser will add the perfect atmosphere through the
diffusion of essential oils by creating a calming ambiance. This study employs a mixed-method
approach, combining qualitative and quantitative research to assess key objectives, including
user satisfaction, usability, environmental impact, health benefits, and the ease of using the unit
for preparing teas. Additionally, the study examines the table's ergonomic design, ease of
maintenance, and user engagement with hydroponic gardening. By measuring these objectives,
the research provides a comprehensive understanding of user preferences for design and
functionality. The Hydro-Grow Tea Unit represents an innovative solution for modern lifestyles
and contributes to improving health while enriching indoor spaces aesthetically

A Preliminary Investigation
No full textPurpose: This study assesses how well the digital dietary diaries manage eating habits among
Effat university students. Digital technologies such as fitness health applications provide
scalable solutions for eating behavior disorders, which are becoming more and more
common. Nevertheless, little is known about their use in Saudi Arabia. This study aims to
address this gap by assessing the impact of dietary diaries on students' eating behaviors and
moods.
Methods: The design is a quasi-experimental approach. To assess improvements in eating
behaviours before and after using the diary, quantitative data is gathered using the Eating
Attitude Test (EAT - 40) and (Mood and Feelings Questionnaire - MFQ). Participants log in
their meals, feelings, and behaviours over a period of 7 days. Open-ended questions were
used to collect qualitative data in order to investigate participants' experiences, and
difficulties. For quantitative results, statistical methods were used to analyze the data; for
qualitative findings, content analysis was employed.
Implications: The study has a number of significant ramifications. By assessing the ability of
dietary diaries to effectively regulate eating behaviours, it contributes to the larger field of
behavioural health and increases our understanding of digital health interventions. The results
could guide the creation of therapies specifically designed to meet the nutritional
requirements and emotional difficulties of college students. The study closes a significant
vacuum in regional research on digital health tools in Saudi Arabia by concentrating on
students at Effat University. It also lays the groundwork for upcoming longitudinal research
and the broader use of digital health resource
Challenges and Opportunities for Transportation Management Systems
No full textNew opportunities and challenges for TMS shall be created with the ever-evolving pace
of AV technology development that will change the logistics and transportation sectors beyond
recognition. This thesis elaborates on various implications to road freight brought to bear by the
integration of AVs, bringing about operational efficiency, cost savings, and methods of
enhancing the delivery process.
From a detailed and systematic literature review using 15 academic articles between the years
2015 to 2025, it was possible to identify major themes concerning the adoption of AVs with
respect to such topics as operational efficiency, cost savings, and barriers to implementation. Key
findings suggest that AVs will minimize human-mediated errors, enable round-the-clock
operations, and offer real-time data for enhanced route optimization. These transitions come with
their challenges. Issues like regulatory uncertainty, public safety concerns, and workforce
resistance need to be treated as substantial issues in the domain of management and industry to
realize the potential benefits associated with AV integration fully
Determinants of Cash Holdings in GCC Region
No full textThis dissertation investigates the firm-level financial determinants of corporate cash holdings in the Gulf Cooperation Council (GCC) region, addressing a significant gap in the literature concerning the unique economic and institutional context of these oil-dependent, financially segmented economies. Drawing on theories such as trade-off, pecking order, agency, and precautionary motives, the study emphasizes the need for a nuanced, region-specific approach to understanding liquidity management. Using annual data from 14 publicly listed GCC firms between 2006 and 2022, the research employs a robust econometric model to analyze the impact of detailed financial statement variables including operating expenses, net income available to common shareholders (adjusted), cash from operating activities, total assets, total liabilities, working capital, and equity before minority interest on cash-holding behavior
How Do Influencers Affect The Buying Habits of Females in Saudi Arabia
No full textThis study analyzes the impact of social media influencers (SMIs) on female consumers in Saudi Arabia. With the expansion of social media platforms and the introduction of influencer marketing, marketers have discovered a new way to communicate with their target audience, particularly Saudi women, who actively participate on platforms such as Instagram, Snapchat, and Twitter. Despite substantial studies on influencer marketing in Western contexts, its efficacy and subtleties in the Middle Eastern region, particularly in conservative nations such as Saudi Arabia, are mostly unknown. This study seeks to close this gap by investigating the processes by which SMIs influence consumer behavior, with a particular emphasis on impulse buying patterns online. This study uses a quantitative approach, including questionnaires, to determine the subconscious characteristics that drive the influencer-consumer interaction in the Saudi market. This study contributes to a better understanding of influencer marketing dynamics in Saudi Arabia by clarifying the function of SMIs, studying cultural contexts, and looking at aspects like authenticity and collaborative efforts with companies
Optimizing Thermo-Electric Generation with Quasi-Z-Source Converter in Energy Harvesting for Wearable Devices
No full textRecent advances in semiconductors industry and microelectronics have created new opportunities for integrating various technologies in energy harvesting projects. These advancements have simplified the process of capturing energy from different sources, such as thermal energy, and converting it into electrical power. Thermo-Electric Generators (TEGs) are commonly used in many applications such as wearable devices. However Thermo-Electric Generators produce very low output voltages, which is insufficient for most low-power electronic circuits to operate. Therefore, a boost converter is essential to step up the voltage output from the TEG to a usable level. In this paper, a DC-DC converter with a high performance in terms of voltage gain is implemented. The proposed quasi-Z-source (q-ZSC) DC-DC converter not only offers high voltage gain but also several significant advantages. The proposed q-ZSC is capable of both boosting and regulating the voltage output efficiently, even under variable input conditions, making it highly suitable for low-power energy harvesting systems such as Thermo-Electric Generators . The design is simulated using MATLAB Simulink software, focusing on integrated circuits, with a strong emphasis on optimizing the circuit’s efficiency. This work underscores critical factors in improving energy harvesting circuits, enhancing their performance and effectiveness in low-power applications for wearable technology
Loneliness and susceptibility to social pain mediate the association between autistic traits and psychotic experiences in young non-clinical adults
No full textUnderstanding of the mechanisms involved in the occurrence of psychotic experiences (PEs) in highly autistic individuals is crucial for identifying appropriate prevention and intervention strategies. This study aimed to investigate the mediating role of susceptibility to social pain and loneliness in the relationship between autistic traits (ATs) and PEs in adults from the general population of 12 Arab countries. This cross-sectional study is part of a large-scale multi-country research project. A total of 7646 young adults (age range 18–35 years, mean age of 22.55 ± 4.00 years and 75.5% females) from twelve Arab countries (i.e., Algeria, Bahrain, Egypt, Iraq, Jordan, Kingdom of Saudi Arabia, Kuwait, Lebanon, Morocco, Oman, Palestine, and Tunisia) were included. Mediation analyses showed that, after adjusting over confounding variables, both loneliness (indirect effect: Beta = 0.18; Boot SE = 0.02; Boot CI 0.14; 0.21) and social pain (indirect effect: Beta = 0.03; Boot SE = 0.01; Boot CI 0.001; 0.05) partially mediated the association between ATs and PEs. Higher ATs were significantly associated with more loneliness and susceptibility to social pain, and directly associated with more severe PEs. Finally, higher loneliness and susceptibility to social pain were significantly associated with greater PEs scores. Findings indicated that individuals with higher ATs tend to experience greater loneliness and feel more pain from rejection, which can in turn be associated with higher levels of PEs. Interventions targeting susceptibility to social pain and loneliness as a means of mitigating PEs among highly autistic adults should be considered
