The Influence of Social Media Content Engagement on Adolescent Mental Health and Wellbeing: Introducing a New Measure of Social Media Use

This study examined how amount of social media use, type of content and type of engagement relate to adolescent mental health and wellbeing. It also explored whether gender and social comparison orientation moderated these relationships. Using a cross-sectional survey study design, objective screen time data and self-report measures of content (photo, video, and text) and engagement (passive vs. a

Analysis and Prediction of Cyber-Threat Fragments in Banking Critical Infrastructure Sector

Continued digitization has seen the banking sector which is positioned as a national critical infrastructure face an ever-growing number of cyber-threats. This, has necessitated the need for proactive measures for detection and prevention, owing to an expanded threat landscape. This thesis proposes an approach centered on leveraging data analysis and Machine Learning (ML) to analyze and predict th

Protocol for 3D direct reprogramming of human glia into dopaminergic neurons with gene expression and immunocytochemistry validation

Direct reprogramming of somatic cells into neurons offers a promising strategy for studying neurological disorders and developing cell-based therapies. This protocol describes the 3D direct reprogramming of human glial progenitor cells into dopaminergic neurons. It includes spheroid formation, lentiviral transduction, neuronal induction using doxycycline, and validation via gene expression and imm

European Consumers’ Perceptions of Chinese Smartphone Brands: At the Intersection of Nation Brand Image, Country-of-Origin, and Product Brand Image

Purpose: To investigate how the nation brand and country-of-origin of China jointly influence the European consumers’ perceptions towards Chinese smartphone brands. The reputation of Chinese smartphone brands in Europe is shaped by European consumers' concerns about China's national image over their global success and technological advancements. Hence, this study focuses on how these perce

Reactivate the river Piura for a sustainable urban future, Peru

As a Latin American country, Peru faces numerous challenges due to the fast urban development without adequate urban planning. Consequently, many Peruvian cities grapple with the repercussions of natural disasters. One of those is Piura characterized by its hydrology because of the quantity of basins it has, and the fast increase of population over the last 60 years. Because of its hydrology and

The Ocean and Us - An exploratory qualitative interview study on ocean-society relationships in the Maldives

The ocean’s importance for human survival is indisputable. However, humanity's continuous impact on the ocean negatively affects its well-being. While this interrelation is acknowledged, only a few studies research the relationship between the ocean and societies. Thus, this study aimed to explore whether specific concepts and theories are necessary when analysing ocean-society relationships.

Examensarbetet Utveckling av monteringssystemet på PVB – ITT Flygt

Work Shop B at ITT Flygt manufactures submersible pumps primarily for the construction industry and are today using an assembly principle, working on benches. Because of the demand on short delivery times and great variations of orders during the year there is a high pressure on the work shop. Because of the aspects above, the work shop wants to investigate whether it is possible to find a model f

Exercising Responsibility in the Seafood Supply Chain: A Case Study on How a Retailer Implements its Commitment to Sustainable Seafood & Experiences of Other Seafood Buyers

The current status of overexploited fish stocks worldwide and increasing stakeholder expectations that retailers should responsibly source products have led to an increasing number of food retailers committing to sell sustainable seafood. Yet, the complexity and variety of seafood supply chains and the challenge inherent in the verification of sustainability qualities suggest that the implementati

“Hej, vad kan jag hjälpa dig med?”

Allt fler organisationer använder sig idag av det digitala kommunikationsverktyget “chatbots” i sin kundtjänst för att kommunicera med sina användare. Den främsta anledningen till att chatbots i form av kundtjänst blir allt vanligare på organisationers webbsidor är att de kan effektivisera verksamheten och därmed reducera kostnader. Det har alltså skett en förändring i hur organisationer kommuniceToday, organizations are using the digital communicative tool ‘chatbot’ in their cus-tomer service to communicate with their customers. The main reason for using this new technology on organizations’ websites is that chatbots can make the customer service more efficient, hence reduce organizational costs. As a result, the chatbots have altered the way organizations and customers communicate with o

Faktorer som påverkar individers inre motivation för träning

Studien ämnade att undersöka vilka faktorer som påverkar individers inre motivation för träning och hur sambandet mellan dessa faktorer såg ut. Faktorerna som undersöktes var upplevd kompetens, upplevd autonomi, upplevd samhörighet, utseende-motiv, ansträngning, fitness-motiv, genomsnittligt spenderade timmar på träning, genomsnittligt spenderade timmar på arbete eller studier och generell self-efThis study was aiming to investigate which factors influence individual’s intrinsic motivation for exercise and what their correlation to it was. The factors examined was perceived competence, perceived autonomy, perceived relatedness, appearance motives, effort, fitness motives, average hours spent on exercise, average hours spent working or studying, and general self-efficacy. The study chose to

Evolution of estrogen receptor status from primary tumors to metastasis and serially collected circulating tumor cells

Background: The estrogen receptor (ER) can change expression between primary tumor (PT) and distant metastasis (DM) in breast cancer. A tissue biopsy reflects a momentary state at one location, whereas circulating tumor cells (CTCs) reflect real-time tumor progression. We evaluated ER-status during tumor progression from PT to DM and CTCs, and related the ER-status of CTCs to prognosis. Methods: I

A critical analysis of organizational transformation – PSR

Purpose: Hunter Harrison, CEO of the railroad company CSX, died on December 16, 2017. Harrison, known as the railroad transformation guru, was a controversial person. While his transformations were applauded by investors, they were also subject to significant criticism. The author changes triggered service disruptions, customer complaints and federal scrutiny. The purpose of this paper is to condu

New perennial grains in African smallholder agriculture from a farming systems perspective. A review

Perennial grain crops are gaining increased attention from researchers as one possible solution to agriculture’s many sustainability challenges. In the Sub-Saharan African context, perennial varieties of crops such as sorghum, rice, and pigeon pea have potential to provide numerous benefits for smallholder farmers. The introduction and adoption of new crops and practices is however a complex proce

Diversity and abundance of microbial communities in uasb reactors during methane production from hydrolyzed wheat straw and lucerne

The use of straw for biofuel production is encouraged by the European Union. A previous study showed the feasibility of producing biomethane in upflow anaerobic sludge blanket (UASB) reactors using hydrolyzed, steam-pretreated wheat straw, before and after dark fermentation with Caldicellulosiruptor saccharolyticus, and lucerne. This study provides information on overall microbial community develo

On the value of SHM in the context of service life integrity management

This paper addresses the optimization of structural health monitoring(SHM) before its implementation on the basis of its Value of Information (VoI). The approach for the quantification of the value of SHM builds upon a service life cost assessment and generic structural performance model in conjunction with the observation, i.e. monitoring, of deterioration increments. The structural performance i

Quantification of the value of structural health monitoring information for fatigue deteriorating structural systems

This paper addresses the quantification of the value of structural health monitoring (SHM) before its implementation for structural systems on the basis of its Value of Information (VoI). The value of SHM is calculated utilizing the Bayesian pre-posterior decision analysis modelling the structural life cycle performance, the integrity management and the structural risks. The relevance and precisio
