This thesis investigates how startups in Tier 2 European cities achieve sustainable growth by engaging with their local entrepreneurial ecosystems. While prior research has largely focused on major capital cities, this study aims to understand how emerging urban canters with less mature infrastructures can still support high-growth entrepreneurial activity. A qualitative research design was employ

This study investigates the corrosion behavior of a magnesium-zinc (Mg-Zn) alloy in a simulated body-like environment, with the aim of optimizing its degradation rate for biodegradable medical implant applications. These implants are designed to support bone healing and then gradually degrade once no longer needed, thereby eliminating the need for additional surgery. Magnesium alloys are promising

In the evolving landscape of digital entrepreneurship, social media influencers (SMIs) have emerged as strategic actors navigating complex stakeholder environments to sustain long-term business viability. While existing literature extensively addresses branding, authenticity, and audience engagement, it often overlooks the strategic coordination required to manage stakeholder relationships across

Electricity grids are essential to industrialized societies, yet they are increasingly unable to meet the dual demands of increased electrification and electricity system decarbonization. Smart grids offer a solution to these challenges by integrating information and communication technologies into the physical grid. However, despite their potential, smart grid implementations often fail to delive

This thesis examines how Sweden’s new development policy, Development for a New Era, reconfigures the agency of its civil society organizations (CSOs). The policy marks a major shiftin Sweden’s foreign aid landscape, moving from a human rights– and needs-based approach to one driven by strategic, trade, and migration interests. Drawing on a qualitative analysis of interviews with CSO staff and med

After the Higgs boson’s discovery precision searches for Beyond the Standard Model physics has become a new frontier in fundamental physics research. In extensions to the Standard Model, large combinatorics arising due to the many possibly involved particles in Feynman diagrams stands in the way of performing precision calculations of what such extensions predict. This work investigates the feasib

Osteoarthritis is a multifactorial degenerative disease characterized by the breakdown of articular cartilage (AC), affecting hundreds of millions of people worldwide. Among many treatment options, hydrogels have emerged as promising candidates for cartilage replacement, due to their structural resemblance to the native tissue. Hydrogels can be made from various materials, and this study focuses o

Blood biomarkers have emerged as accurate tools for detecting Alzheimer’s disease (AD) pathology, offering a minimally invasive alternative to traditional diagnostic methods such as imaging and cerebrospinal fluid (CSF) analysis. Yet, the logistics surrounding venipuncture for blood collection, although considerably simpler than the acquisition of imaging and CSF, require precise processing and st

The construction industry is a major contributor to resource consumption and waste generation in the EU, making the transition to circular construction essential. Reuse of building products is an important circular strategy, but large-scale implementation is hindered by limited market maturity and uncertainty regarding product availability. This study aims to investigate the gap between reported a

Finding the optimal subset of individuals to observe in order to obtain the best estimate of the average opinion of a society is a crucial problem in a wide range of applications, including policy-making, strategic business decisions, and the analysis of sociological trends. We consider the opinion vector X to be updated according to a DeGroot opinion dynamical model with stubborn agents, subject

PurposeIn the transformation to the circular economy, circular logistics nodes are becoming increasingly important to, for example, match supply and demand, coordinate flows, increase logistics efficiency and customer utility, and reduce environmental impact. The purpose of this study is to expand our theoretical understanding of the circular retail transformation and its implications for circular

In this thesis we consider different tests for unit roots in the presence of structural change. We present the theory that lies behind unit roots, what we mean by structural change and try to detect the instances that “breaks” occur in the data. When performing a unit root test, when there is a structural change the results are biased toward accepting a unit root. Therefore, special care must be t

This thesis aimed to search for etiological clues about cancer of unknown primary(CUP) by gathering novel information. The Swedish national registries were used and CUP cases were identified according to the seventh revision of the International Classification of Diseases. A consistent increase before the late 1990s and a dramatic decrease afterwards were observed for CUP incidence among Swedes,re

In this paper we first critically review conventional environmental economics. We conclude that the standard theory offers too narrow a perspective for many real world problems and that many theories are not empirically tested. Consequently, environmental economics is at risk of producing aeroplanes without engines. Next, we welcome and discuss some recent trends, particularly the rapid developmen

This paper identifies the factors for adopting Enterprise Resource Planning (ERP) delivered as Software-as-a-Service (SaaS) among small and medium enterprises (SMEs). The authors conducted a two phases' qualitative-methodology: interviews with 20 experts from SaaS vendor (Microsoft) and a case-study with executives in three organizations which implemented vendor's ERP as SaaS (customers). The vend

To achieve significant improvements, there is a need for a systematic approach in Road Safety Management. The first step of such approach is to define the burden of road casualties in the country. Part of defining the burden is the monetary valuation of the prevention of a fatality accident. Such “values of statistical life” are derived in a number of countries, however, there is a large variation

In the present paper combustion of micron-sized aluminum dust cloud has been studied in a quiescent reaction medium with spatially discrete sources. A new thermal model is generated to estimate the flame front speed in a lean reaction environment in different oxidizer concentrations. Different burning time models for aluminum are utilized in the generated thermal model to compare their applicabili

Making decisions between alternatives are challenging when there is weak or unreliable knowledge about the risks and benefits of the alternatives. This requires a trade-off between risks (and benefits). Here, we comment on a recent paper on risk–risk trade-offs and highlight the difficulties of making such trade-offs when the available evidence is of different strength. One current example of a ri
