Developmental Language Disorder and Awareness: Understanding Professional, Public, and Parental Conceptions of DLD : A Scoping Review
No full textBackground: Developmental Language Disorder (DLD) is a neurodevelopmental disorder affecting language acquisition and it yet remains underdiagnosed compared to other neurodevelopmental disorders, such as ASD and ADHD. The aim of this scoping review is to explore how society, family, and/or professionals perceive Developmental Language Disorder, how aware and knowledgeable are as well as the potential misconceptions that occur. The research questions were: How can the level of DLD awareness be exprored among the public, parents, and professionals? In what ways does limited awareness affect the diagnostic process? Method: According to the PCC framework, eight peer-reviewed studies published between 2019 and 2025 were included from five databases (ERIC, CINAHL, PsychInfo, PubMed, and Medline). Results: Overall, the findings demonstrated that there was low awareness and some misunderstandings among the public, caregivers, and professionals. Conclusion: This study emphasizes the need for campaigns, professional development programs, and further research is recommended
How governmental website accessibility affects all users : Adapting Swedish governmental websites’ visual accessibility and how it affects the access to information and services as well as general user experience
No full textMany governmental websites all over the world lack proper accessibility incorporation, despite guidelines being offered by the Web Content Accessibility Guidelines (WCAG). Accessibility is often believed to only improve disabled users' experiences or to disrupt regular users' experiences and is therefore often dismissed in web design. For the purpose of discovering how non-disabled users' subjective experiences and thoughts are affected by visual accessibility changes, we conducted a study where ten participants were shown two versions of five different Swedish governmental websites. They were asked to first rate their experience based on seven questions on a Likert scale. We then conducted a semi-structured interview to gather information about their individual experiences, which served as the foundation for the conclusion in this thesis. The results suggest all users benefit from or are unaffected by accessible features being included. Aspects like text size, contrast, and proficient readability were most commonly mentioned as visual aspects that impacted the non-disabled users' experiences, while letter spacing was less impactful
Evaluating Privacy Protection in Instant Messaging (IM) Applications
No full textThis thesis conducts a comparative analysis of two widely used Instant Messaging (IM) applications—WhatsApp and Signal—focusing on three key areas of user privacy: metadata exposure, transport layer encryption, and backup storage security. Despite both platforms employing endto-end encryption (E2EE) to protect message content, our findings reveal significant differences in how each handles user metadata, cloud dependencies, and backup practices. Through empirical testing using tools such as PCAPdroid and Wireshark, we observe that WhatsApp exposes more metadata and communicates with a broader range of third-party domains, while Signal maintains a minimal infrastructure footprint and stronger cryptographic configurations. The study also uncovers varying levels of transport layer security, with Signal consistently favoring stronger cipher suites and local-only encrypted backups. By highlighting these architectural and behavioral differences, the thesis underscores the importance of holistic privacy protection beyond E2EE. These insights aim to support users, developers, and policymakers in understanding how privacy-bydesign principles are (or are not) implemented in mainstream messaging applications
Investigation of Real-TimeOperating Systems for CAN Communication and Development of a XYZ Node as a Testing Environment
No full textThis study presents a comparative evaluation of two RTOS: Zephyrand SAAB OS (uCOS-II). The purpose is to determine if portingfrom SAAB OS increases the real-time capabilities. This study fo-cuses on the metric: CAN-message response time to determine thereal-time performance. The setup used is a developed XYZ-node,which purpose is to simulate a CAN-message set. The XYZ-nodesends an attribute request which is then responded to by the DUT.The response time is measured using a PicoScope 3000 series. Wefound that Zephyr performed slightly better for all load rates. Whilethese findings suggest a slight performance increase when porting toZephyr, a more conclusive analysis could be made considering otheraspects of the RTOS, such as CPU utilization and scheduling meth-ods. In conclusion this study contributes both to the performanceinsights and methods used to conduct performance tests for real-time systems
Gamified waiting : The Impact of Interactivity on Perceived Waiting Time in Mobile Virtual Queues
No full textThis study investigates how different types of loading screen interactivity, passive, interactive non-gamified, and gamified, affect users’ perceived waiting time and emotional responses in mobile applications. With rising user expectations for fast digital experiences, managing perceived waiting times has become critical, particularly on mobile devices where multitasking options are limited. While prior research has focused on passive and progress-based loading screens, little attention has been given to the role of gamification in virtual queue contexts. An experimental study was conducted with 33 participants, divided into three groups, each exposed to a different loading screen prototype during a simulated tickets-purchase task in a mobile application. Quantitative data were collected through actual and perceived waiting times, analyzed via ANCOVA. Qualitative data from post-test interviews were examined using inductive content analysis. The ANCOVA results showed that actual waiting time had a significant effect on perceived waiting time (p<0.001), while loading screen type did not (p=0.992). However, participants exposed to the gamified prototype waited significantly longer on average, suggesting increased engagement. The qualitative analysis revealed four key themes: emotions response, behaviour during waiting, loading screen expectations, and trust in the system. Participants described gamified screens as more enjoyable but expressed frustration when system feedback was unclear. This study concludes that while gamification did not significantly reduce perceived waiting time (PT), it was effective in sustaining user engagement during wait duration, but users’ emotional and behavioral responses are sharpened by design elements, and clarity in the interface. These results contribute to the existing research by showing that combining interactivity with clear system feedback is essential to improving the mobile waiting experience and can inform more effective UI/UX strategies for virtual queue design.
Challenges in dimensioning and management of safety stock : A case study on the balance between service level and inventory levels in companies within warehouse management and distribution.
No full textPurpose – Companies are challenged in dimensioning their safety buffers in a way that balances desired service level with capital tied up. A high service level is crucial for competitiveness, and safety stock plays a key role in covering volatile and unpredictable demand. A trade-off must be made between safety and capital tie-up. The larger the safety stock, the greater the potential to achieve a high service level – and the capital tie-up. Therefore, the purpose of this study is to: Investigate how global companies can work more systematically and with continuous improvements in managing safety stock, and how this affects service levels and costs. To address this purpose, two research questions have been formulated: [1] What are the challenges in dimensioning and management of safety stock? [2] How can the process of safety stock updates be improved to manage changed conditions? Method – The study is a case study that combines both qualitative and quantitative research. Interviews, documents analysis and workshops have been used as data collection methods to fulfill the purpose of the study and to answer the research questions. The interviews were transcribed, and the results were categorized into five themes relevant to the study. Findings – The findings of the study consist of several challenges that must be considered when dimensioning safety buffers, particularly safety stock. Various factors contributing to uncertainties are identified, as well as the importance of reducing variability. The study identified challenges in dimensioning safety stock and how these challenges can be managed to achieve a balance between service level and capital tie-up, Furthermore, the result shows a lack of clear guidelines and routines for updating safety stock. Implications – The study provides both practical and theoretical implications. The practical implications offer insights into how the dimensioning and monitoring of safety stock can be conducted. The theoretical implications lie in the synthesis of existing theory regarding how trade-offs between service level and capital tie-up should be managed to achieve an optimal balance. Limitations – The study only considers a limited part of the supply chain, with its primary focus on safety buffers in distribution warehouses. Other parts of the supply chain are excluded from the scope of the study. The study is based on the current state of the case company and therefore does not address decisions that have already been made regarding forecasting, segmentation, buffer selection, or established targets for service levels and capital tie-up
Empowering Women for Sustainable Food Security : A Gender-Equitable Approach to Combating Global Hunger, The Role of We Effect Kenya
No full textThis thesis addresses the relationship between food security and gender equality, particularly the role of We Effect Kenya in promoting sustainable and inclusive development. Drawing on the theoretical frameworks of Feminist Political Ecology, Women's Empowerment Theory and Sustainable Livelihoods Framework, this thesis addresses food security and gender equality issues in Kenya by assessing the durability of gender-related interventions, their impact on agricultural production and community well-being, and adopting a qualitative approach to explore how these impacts can be increased. The research is a literature study complemented by an in-depth interview with We Effect Kenya and institutional reports, policy documents and data were reviewed to ensure the comprehensiveness of the study. The implementation of We Effect's gender equality strategies in Kenya was investigated and its impact was assessed. The study not only investigated the impact of gender inequalities on household food security, but also examined this situation in economic, social and environmental terms. By identifying the challenges and opportunities in gender-inclusive food security practices, it provides important information for researchers, policy makers and practitioners working on sustainable food systems and gender equality in Global South.

Paid Family Leave and Women in Politics : The Case of the United States
No full textThis thesis examines whether paid family leave (PFL) policies influence women’s political representation in the United States. While prior research has extensively documented the positive labor market effects of PFL, little is known about its potential political consequences. Building on theories that link female labor force participation to political empowerment, this study investigates whether PFL helps close the gender gap in political leadership. I compile a novel panel dataset covering all 50 U.S. states from 1995 to 2024, combining annual data on women’s representation in state legislatures with detailed information on PFL adoption and relevant socio-economic controls. To identify causal effects, I employ a staggered difference-in-differences design using the Callaway and Sant’Anna (2021) estimator, which accounts for treatment heterogeneity and variation in timing. The findings consistently show no statistically significant effect of PFL on the share of women in state legislatures, across specifications and robustness checks. These results suggest that while PFL supports women’s continued workforce participation, it does not automatically translate into political gains under the U.S. institutional context. The study contributes to the literature by empirically linking labor market policy to political representation and highlights the need for more comprehensive policy strategies to advance gender equality in politics.
Exploring The Determinants Of Consumer Preferences In Last-Mile Delivery Services: An Analysis Of Factors Influencing Delivery Choices And Consumer Satisfaction In Jönköping
No full textThis research focuses on variables that affect consumer demands and satisfaction with the last-mile delivery services in Jönköping, Sweden. Last-mile delivery is an increasingly important aspect of the consumer experience, driven by the rapid growth of e-commerce. The study identifies several key variables by demonstrating that delivery time, delivery cost, flexibility, customer service quality, and environmental impact are significant factors influencing consumer decision-making and satisfaction. It also focuses on the mediating ability of perceived value in creating consumer satisfaction as consumers evaluate delivery services in terms of functional, emotional, and social determinants of the delivery services. A survey of 322 participants was used to stimulate the collection of research data by means of a quantitative research design. Correlation test indicated that there were strong positive correlations between the delivery factors and satisfaction, mainly in the dimensions of delivery time, cost, and customer service. Another fact highlighted in the study is the sustainability consumer decisions grow more important. The research results can be of interest to the providers of the delivery services, giving them practical suggestions, where they should focus to improve the efficiency of the services, lower costs, increase flexibility, and adopt sustainable operations. This study develops the literature on last-mile delivery, particularly in smaller cities and provides guidelines for further research on consumer behaviour in logistics and e-commerc
Framing of Responsibility for Sustainability : A Qualitative Content Analysis of NGO Communication
No full textThe aim of this thesis is to determine how responsibility for sustainability is framed in NGO communication and whether gender plays a role in this framing. The following research question was asked: ‘How is responsibility for sustainability framed in NGO communication and what role does gender play in this framing?’ A qualitative content analysis was carried out to answer the research question. For this analysis five categories are deductively conducted from the literature and later inductively further developed within the selected material. The evaluation of the qualitative content analysis shows that gender does not always play a role for framing responsibility. The responsibility for sustainability is primarily individualised within the selective material and structural causes remain hidden. The material of the thesis consists of four NGOs: Welthungerhilfe (WHH), United Nations Children’s Fund (UNICEF), Bangladesh Rural Advancement Committee (BRAC) and Our Seas Our Future (OSOF)
