This dissertation investigates the extent and evolution of income and educational inequality, as well as governments’ tax and expenditure policies and their implications for inequality in Ghana over the long-term. The results of the dissertation are presented in four-thematically related papers. Paper I uses a social tables approach to measure the extent of income inequality in colonial Ghana and

Law is everywhere – Rätten finns överallt. Det uttrycket kan beskriva rättens roll i våra liv. Utöver formella lagar, regleringar och avtal möter vi i vår vardag även informella lagar och sociala normer: i familjen, i skolan, på arbetsplatsen och i samhället i stort. De styr både hur vi tänker och agerar och vad vi förväntar oss av andra. Rättssociologi handlar om att analysera relationen mellan r

Implementing electrically connected metal-coated posts in a Deterministic Lateral Displacement (DLD) device and applying electric fields, we use electrokinetics to achieve tunable particle separations and to trap and manipulate DNA. The strength of DLD stems from its typically binary behavior. Particles move in one out of two trajectories based on their effective size. For particles that are close

We present a new experimental method for the measurement of the compressibility of cells by analysis of free flow acoustophoresis separation data.

We developed the AcouWash (Figures 1 and 2), a benchtop instrument for flow-through cell and particle separation by acoustophoresis. Building on previous research [1-4] AcouWash can re-suspend cells in new medium, separate cells based on size or acoustic properties, or enrich cells, Figure 3. We present our initial evaluation of AcouWash regarding size-based separation of particles, cell washing,

We report a new method to select the optimal actuation frequencies in bulk acoustophoresis devices, by means of differential impedance spectrum analysis measured via the actuating piezoelectric transducer (piezo). The impedance spectra is rich of large spurious resonance peaks originating from bulk resonances not related to the channel resonance, Fig. 1a, why direct measurement of the piezo impeda

We report a simplified, integrated and more efficient way of preparing DNA for analysis. We have developed a microfluidic platform that can purify DNA and subsequently label and stretch it on a surface. We have successfully extracted DNA from a gel-filled microfluidic channel using electrophoresis and subsequently stretched the DNA linearly by absorption to either a hydrophobic or a positively-cha

How did human symbolic behavior evolve? Dating up to about 100,000 y ago, the engraved ochre and ostrich eggshell fragments from the South African Blombos Cave and Diepkloof Rock Shelter provide a unique window into presumed early symbolic traditions of Homo sapiens and how they evolved over a period of more than 30,000 y. Using the engravings as stimuli, we report five experiments which suggest t

The presence of immune cells in the tumor microenvironment has been associated with response to immunotherapies across several cancer types, including melanoma. Despite its therapeutic relevance, characterization of the melanoma immune microenvironments remains insufficiently explored. To distinguish the immune microenvironment in a cohort of 180 metastatic melanoma clinical specimens, we develope

The inorganic metal or metal-oxide nanoparticles (NPs) that mimic enzymes are of great interest due to improved physical and chemical properties compared with native enzymes. Here, we report that manganese dioxide (MnO2)-Silk exhibit catalase, oxidase, and peroxidase-like activities. The MnO2-Silk hybrid fibers effectively decomposed hydrogen peroxide (H2O2) and oxidized the typical horseradish pe

Previous transcriptome-wide association studies (TWAS) have identified breast cancer risk genes by integrating data from expression quantitative loci and genome-wide association studies (GWAS), but analyses of breast cancer subtype-specific associations have been limited. In this study, we conducted a TWAS using gene expression data from GTEx and summary statistics from the hitherto largest GWAS m

BACKGROUND: The effect of risk-reducing salpingo-oophorectomy (RRSO) on breast cancer risk for BRCA1 and BRCA2 mutation carriers is uncertain. Retrospective analyses have suggested a protective effect but may be substantially biased. Prospective studies have had limited power, particularly for BRCA2 mutation carriers. Further, previous studies have not considered the effect of RRSO in the context

Purpose: This paper aims to investigate the nature and dynamics of the interaction between university spin-offs (USOs) and academia. Design/methodology/approach: The theoretical framework is grounded in an interactive view based on the industrial marketing and purchasing literature on USOs and their development. The concepts of activity links, resource ties and actor bonds are used as a starting p
