The annual plastic production was over 400 million tonnes in 2023 and it is expected to keep growing over the years. The increasing use of fossil-based materials and problems regarding the environmental impact of plastic waste motivate the transition towards a circular economy. Interest in 5-hydroxymethylfurfural (HMF) has increased due to the possibility of being a biobased building block in the
Purpose – The first purpose of this study is to identify and categorize the motivational factors, from a customer and managerial perspective, that restaurant patrons have when choosing between the self-service kiosk (SSK) or the human service counter during their fast-food order. The second purpose is to identify potential gaps between the customer and manager perspectives. Methodology – This stud
This master’s thesis examines and evaluates different ways of preserving media reliant on the now defunct Adobe Flash technology. The purpose is dual; both to examine and evaluate Flash preservation from an archival point of view, and to contribute to the existing research on Internet communities’ preservation initiatives. The research and data collection for the thesis is focused on the preservat
his thesis investigates the effects of intra-ASEAN export flows on global FDI inflows into ASEAN member states. A panel dataset including all ten countries of the ASEAN is created to test these effects from 1992 to 2020. Linear regressions without and with fixed effects predict that intra-ASEAN exports have a positive and significant impact on FDI inflows into ASEAN countries. Furthermore, trade f
This research paper analyses the relationship between average excess stock return and market beta on the Nasdaq OMX Stockholm for the period 1999 to 2015. By using the Fama-MacBeth approach and several additional regressions, we are able to examine if the relationship exists on days when the market anticipates receiving news regarding monetary policy decision by the Riksbank, Federal Reserve, Euro
Outsourcing and contract manufacturing have developed as effective business strategies for electronics manufacturing services in the recent years. Most Consumer Electronic brand firms do not actually make the consumer products they sell but hire contract manufacturers, mostly in the developing world. Asia is currently the major production base of mobile phones for instance, with China and ASEAN ac
Payment and bonus schemes based on seed quality used by the Swedish agriculture cooperative Lantmännen is evaluated. Results from a farm and region/time fixed effect model show that the linear payment scheme for pulses (peas and beans) has approximately 15 percentage points lower quality compared to that used for grains when a common quality measure constructed for this research is used. Germinati
This research project presents an example of how students and teachers can work together to analyze Of Mice and Men. In this paper, critical theory is used as a form of scaffolding, in order to both develop students’ Theory of Mind (ToM) and make canonical literature more accessible. The research questions answered in this paper are concerned with asking how critical theory can be applied to the n
Previous studies have entertained the prospect of having 3D models substitute for their dry bone originals in osteological analysis. The objective of this study was to contribute to qualifying to what extent this may be possible given current technology. To this purpose, rather than choosing just a quantitative and purely technical method for evaluating models, as has been the norm in previous stu
Along with a deeper integrated world economy have countries discovered the benefits of harmonizing and simplifying the procedures linked to international trade, referred to as trade faciliation. A quite unexplored part of this field of research is yet how trade facilitation affects international investment flows, referred to as Foreign Direct Investments (FDI). In theory is trade facilitation affe
This thesis investigates credit risk management in Nordic commercial banks and its effect on profitability. Two determinants of credit risk are chosen according to relevant literature, namely loan loss provision ratio and capital adequacy ratio. Thirteen banks in total are then investigated across the 16 year time frame from 2000-2015. The results seek to address two essential questions. Firstly,
Conductance was calculated for trapezoidal nanowires with different forms and strengths of imperfection using kwant, a quantum transport software package that uses a tight-binding model. In this thesis it is found that increasing magnitudes of different imperfections such as surface charge and roughness roughen conductance steps, introduce resonances, and lower conductance overall with different c
Background and Objectives: This project explored the needs of art galleries and collectors for Digital Asset Management Systems (DAMS), in order to fill an existing knowledge gap and help companies to analyse these needs. Bespoken difficulties in the field significantly challenge the development of DAMS and have thus also hampered the evolvement of high-quality systems for the art market. There se
Abstract Recent financial crises have demonstrated the importance of accurately measuring financial risks in order to be able to employ mitigating risk policies. This essay investigates the question whether a GARCH model augmented by an autoregressive conditional jump intensity component can improve value-at-risk forecasts in comparison to common GARCH models. Therefore, the VaR forecasting perfor
I provide evidence on the impact of pre-primary school expansion on maternal labour supply in the context of South Africa. I draw on administrative data from the South African National Census in 2001 and 2011, and a Community Survey in 2007, to extract household information. My identification strategy exploits the staggered timing and intensity in the expansion of pre-primary school facilities acr
Plenty of research has been made on strategic asset allocation, but the focus on foreign market exposure is sparse. This paper analyzes how the investor’s portfolio choice is affected when exposed to four foreign assets, one domestic asset, and the risk free interest rate. Two models are developed using dynamic programming for an investor with iso-elastic utility and lognormal asset returns. The p
The viscosity of concentrated casein solutions play a vital part in the product quality of medical nutrition as well as for the energy consumption in spray drying. Previous work has shown that a lower viscosity can be achieved through processing (Hemar et al. 2011). This project focused on the effect on temperatures on micellar casein isolate (MCI). A temperature range of 5-90 °C has been studied
With estuarine bacterioplankton as a key player in the nutrient cycle and the amount of DOC transported to sea increasing, it is important to gain a better understanding of how the processes within the catchment and estuary control the degradation of DOC by bacterial communities. Future climate change scenarios add a new dimension to this question, with predicted precipitation increases translatin
