Bulding Resilient Supply Chain : A Qualitative Study of How Covid-19 Affected Supply Chain Resilience in Swedish Small and Medium-Enterprises

Synnergren, Robin, Brauer, Jacob January 2023 (has links)
Modern supply chains are often characterized by carefully planned and interconnected processes that seamlessly integrate with each other. Supply chains are often efficientduring a stable business environment but are highly vulnerable to risks and disruptions.When any link in the supply chain is negatively impacted, challenges can arise for all the companies in the supply chain. This has expanded the goal of supply chain management tocreate resilient supply chains that incorporate event readiness, provide efficient and effective responses, and can return to their original state after a disruption. During Covid19 businesses all over the world were affected and the pandemic led to disruptions in supply chains. Small and medium-sized enterprises (SME) were especially affected because of lack in financial resources, technical capabilities, and low resilience. SMEs play a crucial role in the global economy but there is still a limited amount of research onhow SME can achieve resilience in their supply chains. Furthermore, there is a lack ofresearch comparing changes in supply chain resilience before and after Covid-19. To address this research gap, the purpose of the study is to explore how Covid-19 affected the supply chain resilience in Swedish SMEs. To understand the effects of Covid-19 we will examine supply chain resilience in SMEs before, during and after the pandemic. To address our purpose, we have conducted a qualitative study using an inductive approach and exploratory research design. We collected primary data from semi-structuredinterviews with nine managers from manufacturing Swedish SMEs. The data gathered through the interviews was analysed by using a thematic analysis that led us to our findings. Our findings revealed that prior to the pandemic, risk awareness was not a top priority for the respondent companies. However, Covid-19 exposed vulnerabilities in their supply chains highlighting the importance of both proactive and reactive strategies. Swedish SMEs experienced various challenges including transportation problems, component shortages and fluctuations in customer demand. Tomeet these challenges, the companies showed flexibility by changes in product assemblingand increased inventory levels during Covid-19. Furthermore, strengthened communication with suppliers and customers played a significant role in increasing supply chain visibility and collaboration. As a result of the Covid-19 disruption, our study show that the responding companies have become more aware of risks and incorporated practices into in their operations as adoption of alternative suppliers, optimization of safety stocks and improved communication. Overall, the findings suggested that the pandemic prompted the respondent SMEs to strengthen their supply chain resilience. By learning from the impact of the crisis, these companies have become more resilient and created supply chains that can better withstand future disruptions. This study contributes to understanding how supply chain resilience in Swedish SMEs was affected by Covid-19 and how SMEs can enhance their supply chain resilience

Earning management in Swedish listed firms during the Covid-19 pandemic

Aspegren, Niklas, Gillmert Hansen, Niklas January 2023 (has links)
This study examines the prevalence of earnings management during the covid-19 pandemic in Swedish listed firms and aims to provide further evidence regarding earnings management practices during the pandemic. The study further investigates whether there are any differences between industries in terms of engaging in opportunistic accounting procedures. Previous research on earnings management during the covid-19 pandemic exclusively examines the year of 2020 as pandemic period. This study aims to contribute with further evidence by expanding the pandemic period and including the fiscal year of 2021, adding one additional fiscal year largely affected by the pandemic. Previous studies on the area finds contrasting results, where some studies find that firms tend to pursue income-increasing practices, while others deliberately decrease financial performance during a crisis. In order to perform this study, the modified Jones model is used to detect accrual-based earnings management through abnormal levels of discretionary accruals. The result of this study finds significantly increased levels of income-decreasing accrual-based earnings management, potentially suggesting that firms engaged in “big bath accounting” during the pandemic in order to boost financial performance in future periods. Additionally, the results show significantly increased levels of income-decreasing earnings management in 2/8 industries.

WHO CAN WE LISTEN TO AMID THE UNCERTAINTIES AND RISKS OF THE COVID-19 PANDEMIC? A COMPARATIVE CASE STUDY ON PUBLIC RHETORICS OF TWO INFLUENTIAL PUBLIC HEALTH EXPERTS FROM CHINA AND THE UNITED STATES

Jianfen Chen (14817964) 10 July 2023 (has links)
<p>In today’s interconnected world, public health crises like COVID-19 have a widespread impact, transcending national borders, causing economic upheaval, the loss of trillions of dollars from the gross domestic product (GDP), and significant disruptions to health systems, and forcing millions of individuals into poverty. While countries may differ in their responses to these crises, their shared objective is to mitigate the damage and ultimately bring an end to the outbreak. Public health experts play a crucial role in these efforts, utilizing rhetorical strategies to effectively communicate with the public about the pandemic. Notably, during the COVID-19 pandemic, Dr. Anthony Fauci in the United States and Dr. Wenhong Zhang in China emerged as revered figures, leading public health experts, and adept communicators in addressing the risks posed by the pandemic in their respective countries. This dissertation investigates the rhetorical practices of Dr. Zhang and Dr. Fauci in their communications about the pandemic to their respective publics. Employing a case study approach, contextualized comparative rhetoric as an inquiry method, and computer-assisted qualitative rhetorical analysis, this dissertation identifies the similarities and differences in the rhetorical strategies adopted by the two doctors. The findings reveal that both doctors utilize similar rhetorical tools, including ethos, kairos, narratives, and metaphors, to effectively communicate about the pandemic to the public. However, they also exhibit differences influenced by contextual factors such as political, social, and cultural contexts. These findings contribute to our understanding of the role of rhetoric in public health experts’ communications about the pandemic in different countries during a global public health crisis.</p>

Förbättras insiders prediktionsförmåga av Covid-19 pandemin? : En kvantitativ studie

Mourad, Daniella, Chung, Kelly January 2023 (has links)
Insider trading occurs daily and previous studies show that trading might even increase during volatile times. The market becomes especially volatile and uncertain during an economic crisis, such as the Covid-19 pandemic. In addition to that, previous studies show that the information asymmetry between insiders and outsiders increases during economic crises, giving the insiders an information advantage. Due to that, we investigate whether insiders, specifically CEOs, can use their advantage to predict future profitability during the Covid-19 pandemic in comparison to a time prior. The data consists of insider transactions on the Swedish stock market during 2017 and 2020. To test our hypothesis we use multiple linear regressions to see if there are any connections between our variables. Our results indicate that there is a connection between the volume of insider transactions and whether the pandemic is ongoing or not. However, our results do not indicate that insiders' ability to predict future profitability increases during an economic crisis. Despite that, the results seemingly differ depending on the industry.

HOW DID INTERNATIONAL MEDIA FRAME SWEDEN’S HANDLING OF THE COVID-19 PANDEMIC? : A Case Study of Swedish “Exceptisionalism” And The Swedish “Image” During Pademic

Adhikari, Purushottam January 2023 (has links)
This study investigates how the international media framed Sweden's response to the COVID-19 pandemic and its image during this time. By utilizing framing theory as an analytical framework, 42 articles from The Guardian and The Washington Post were analyzed. Hence, based on the existing framing research, by Semeteko and Valkenberg (2000), the coverage is classified into five frames: conflict, human interest, economic consequence, morality, and responsibility. The findings highlight how the media coverage of a nation during crises can shape its national image. Moreover, the study underscores the significance of comprehending how media can influence future global crisis reporting. This thesis contributes to the existing body of literature pertaining to the media framing of crises by analyzing the portrayal of Sweden's exceptionalism and image by the international media in the context of the COVID-19 pandemic. Through an examination of news coverage from prominent outlets, the study identifies the dominant frames used to portray Sweden's response and shape its image. The findings reveal a diverse range of frames employed, including conflict, human interest, economic consequence, morality, and responsibility, reflecting the complexities surrounding Sweden's approach. This research emphasizes the importance of comprehending media framing in shaping national image during global crises and advocates for holistic approaches to address societal, economic, and public health impacts. Finally, the study’s findings indicated that Sweden's national image in the context of its response to the COVID-19 pandemic is multifaceted and complex, based on the analysis of the various frames used in the articles. The dominant frames shape Sweden's perception of itself as a nation characterized by opposing opinions, controversies, ongoing debates, personal experiences, moral considerations, and a delicate balance between economic and social concerns. Sweden is framed as a nation that values individual liberty, individual responsibility, and a distinctive approach to crisis management.  Overall, Sweden's national image reflects a dynamic and complex perspective, illuminating the complexities and diverse perspectives surrounding its response to the COVID-19 crisis.

Changes in alcohol use during the COVID-19 pandemic in Europe: A meta-analysis of observational studies

Kilian, Carolin, O'Donnell, Amy, Potapova, Nina, López-Pelayo, Hugo, Schulte, Bernd, Miquel, Laia, Paniello Castillo, Blanca, Schmidt, Christiane Sybille, Gual, Antoni, Rehm, Jürgen, Manthey, Jakob 02 February 2024 (has links)
Numerous studies have examined the impact of the COVID-19 pandemic on alcohol use changes in Europe, with concerns raised regarding increased use and related harms. Approach. We synthesised observational studies published between 1 January 2020 and 31 September 2021 on self-reported changes in alcohol use associated with COVID-19. Electronic databases were searched for studies evaluating individual data from European general and clinical populations. We identified 646 reports, of which 56 general population studies were suitable for random-effects meta-analyses of proportional differences in alcohol use changes. Variations by time, sub-region and study quality were assessed in subsequent meta-regressions. Additional 16 reports identified were summarised narratively. Key Findings. Compiling reports measuring changes in overall alcohol use, slightly more individuals indicated a decrease than an increase in their alcohol use during the pandemic [3.8%, 95% confidence interval (CI) 0.00–7.6%]. Decreases were also reported more often than increases in drinking frequency (8.0%, 95% CI 2.7–13.2%), quantity consumed (12.2%, 95% CI 8.3–16.2%) and heavy episodic drinking (17.7%, 95% CI 13.6–21.8%). Among people with pre-existing high drinking levels/alcohol use disorder, high-level drinking patterns appear to have solidified or intensified. Implications. Pandemic-related changes in alcohol use may be associated with pre-pandemic drinking levels. Increases among high-risk alcohol users are concerning, suggesting a need for ongoing monitoring and support from relevant health-care services. Conclusion. Our findings suggest that more people reduced their alcohol use in Europe than increased it since the onset of the pandemic. However high-quality studies examining specific change mechanisms at the population level are lacking.
