It has been argued that the fundamental cause of Africa’s current relative poverty is a lack of pro-growth institutions deriving either from the colonial system, the period of slavery, or from particular geographic or population characteristics. This article takes a fresh look at estimates of African country incomes. It subjects the available datasets to tests of accuracy, reliability, and volatil
Male Barn Swallows (Hirundo rustica) help their mates to incubate in North America but not in Europe. In this study, conducted at four colonies in southeastern Canada, males contributed an average of 9% of the total amount of incubation during daylight hours. The total percent of time that eggs were incubated (nest attentiveness) by both sexes declined through the day, largely due to a response to
Aim: The treatment of peritoneal surface malignancies ranges from palliative care to full cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy, HIPEC. Ongoing monitoring of patient recruitment and volume is usually carried out through dedicated registries. With multiple registries available worldwide, we sought to investigate the nature, extent and value of existing worldwide CRS an
Our chapter illustrates how citizens can enact varying styles and degrees of political engagement through social media. It also investigates if citizens engage with political content in ways unhindered by national boundaries. We distinguish between three primary types of content styles (factual, partisan and moral) and four degrees of engagement (making, commenting, diffusing and listening). Moreo
Type 1 diabetes is an autoimmune disease arising from the destruction of pancreatic insulin-producing beta cells. The disease represents a continuum, progressing sequentially at variable rates through identifiable stages prior to the onset of symptoms, through diagnosis and into the critical periods that follow, culminating in a variable depth of beta cell depletion. The ability to identify the ve
Ytan av alla celler är dekorerad med kolhydrater som står för mycket av den information en cell överför till omgivande celler. Många av kolhydraterna tillhör en föreningsklass som kallas proteoglykaner som består av ett protein sammanbundet med en eller flera långa kolhydratkedjor. Dessa kolhydratkedjor kallas glykosaminoglykaner och är bundna till proteinet via kolhydraten xylos. Än så länge har β-1,4-Galactosyltransferase 7 (β4GalT7) is a key enzyme in the biosynthesis of proteoglycans (PGs) and glycosaminoglycan (GAG) chains, which are important macromolecules involved in many biological processes such as cell growth and cell signaling as well as in cancer pathobiology and viral and bacterial infections. Despite its pivotal role, much is still unknown regarding the specific structure of
Human pluripotent stem cells (PSCs) are widely used for studying embryonic development, disease modelling, drug discovery and cell therapy development. Using human PSCs as a model has significantly contributed to our understanding of embryonic development and elucidating novel pathological mechanisms as well as developing new drugs. However, there are significant genetic and epigenetic variations
The third sector of national innovation systems comprises non-academic, publicly owned R&D organizations that complement universities and private-sector firms and are normally called ‘research institutes’. Scholarly attention to these organizations has been scarce, partly a consequence of the theoretical imbalance in favor of conceptualizations of innovation processes as requiring mainly unive
Purpose. Children with cerebral palsy (CP) are at increased risk for hip dislocation. This can be prevented in most cases using surveillance programmes that include radiographic examinations. Known risk factors for hip dislocation include young age, high Gross Motor Function Classification System (GMFCS) level and high migration percentage (MP). The head-shaft angle (HSA) has recently been describ
Research has been lacking on the natural history, complications, and treatment of haemophilia B, which is less common than haemophilia A and was recognized as a distinct clinical entity in 1947. Although the two diseases share the same clinical manifestations, they differ in causative mutation, risk of inhibitor development, and patient quality of life. Frequently debated is whether haemophilia B
Cartilage oligomeric matrix protein (COMP) is a soluble pentameric protein expressed in cartilage and involved in collagen organization. Tissue microarrays derived from two cohorts of patients with breast cancer (n=122 and n=498) were immunostained, revealing varying expression of COMP, both in the tumor cells and surrounding stroma. High levels of COMP in tumor cells correlated, independently of
In this chapter, we explore whether eyeblinks can be used as a measurementof spectators’ narrative transportation into a cinematic narrative. In ourexperiment, we show that spectators’ eyeblinks increase when watchingfilm clips together with what might be called congruent music. Increasedeyeblinks indicate an emotional arousal that motivates attention, whichin turn is a prerequisite for narrative
We develop a behavioural framework of bounded rational decision-making under uncertainty to analyse the role of technological dynamism in the firm’s environment for its decision to internationalise innovation. Applying prospect theory, we argue that technological uncertainty in the firm’s environment affects its risk preferences differently depending on its technological capabilities. A key predic
