The health returns of attending university for the marginally eligible student

A key policy question is whether continued expansion of university education is beneficial for the marginally eligible student. In this paper we exploit an arbitrary university eligibility rule combined with regression discontinuity design to estimate the causal effect of university attendance on healthcare utilization amongst young adults in Sweden. We find that the eligibility rule leads to a cl

Physicochemical metamorphosis of re-aerosolized urban PM2.5

The toxicity of particulate matter (PM) is dependent on particle physical and chemical properties and is commonly studied using in vivo and in vitro approaches. PM to be used for in vivo and in vitro studies is often collected on filters and then extracted from the filter surface using a solvent. During extraction and further PM sample handling, particle properties change, but this is often neglec

From tool making to pictures : a design semiotics approach

Studies on cultural evolution from archaeology, neuroscience and cognitive semiotics have shown the role of tool making for development of novel cognitive capabilities in early humans. Therefore, it is reasonable to assume that tool making was a cognitive threshold from nonhuman primates to hominins. Tool making begun with rudimentary skills for tool production based on motor patterns, learned soc

The notion of agency and the material engagement theory : An Agentive statement

Malafouris (2013) proposes that agency is an emergent product of the relational ontology of our material engagement. However, I suggest a distinction between meaning and agency for a better understanding of our relational ontology with things. Meaning is the payoff of the relational ontology, meaning emerges when an agent act within the world. Agency is the capability to act, signify, produce and

Model-free MIMO control tuning of a chiller process using reinforcement learning

The performance of HVAC equipment, including chillers, is continuing to be pushed to theoretical limits, which impacts the necessity for advanced control logic to operate them efficiently and robustly. At the same time, their architectures are becoming more complex; many systems have multiple compressors, expansion devices, evaporators, circuits, or other elements that challenge control design and

Inter-Professional Caring for Children Who Are Relatives of Cancer Patients in Palliative Care: Perspectives of Doctors and Social Workers

Background: A palliative cancer diagnosis in a parent has a major impact on many aspects of their children’s lives. Studies show that professionals in the oncological field do not seem to offer relatives, in general, much attention. Aim: to explore how doctors and social workers handle children of cancer patients in order to understand the possibilities and difficulties in supporting children in s

Taxation in Africa since colonial times

This chapter focuses on taxation in Africa since 1900. Using existing data and insights from the literature, the chapter documents taxes collected by colonial and post-colonial states, exploring what was taxed, the types of taxes, the tax revenue patterns and the socio-political contexts shaping taxation policies. It begins by discussing the fundamental principles of taxation and forms of direct a

Meningioma microstructure assessed by diffusion MRI : An investigation of the source of mean diffusivity and fractional anisotropy by quantitative histology

BACKGROUND: Mean diffusivity (MD) and fractional anisotropy (FA) from diffusion MRI (dMRI) have been associated with cell density and tissue anisotropy across tumors, but it is unknown whether these associations persist at the microscopic level.PURPOSE: To quantify the degree to which cell density and anisotropy, as determined from histology, account for the intra-tumor variability of MD and FA in

A saturated map of common genetic variants associated with human height

Common single-nucleotide polymorphisms (SNPs) are predicted to collectively explain 40–50% of phenotypic variation in human height, but identifying the specific variants and associated regions requires huge sample sizes1. Here, using data from a genome-wide association study of 5.4 million individuals of diverse ancestries, we show that 12,111 independent SNPs that are significantly associated wit
