Inorganic lead is the most extensively studied environmental toxin. Today's humans have in the order of 100 times higher lead exposure, compared to prehistoric humans, mainly from food. The exposure was even higher during the 20th century, mainly due to lead addition to gasoline. Today, high exposures occur in many occupations, but also through, for example, contaminated drinking water, traditiona
With the aim of understanding how the International Criminal Court (ICC) affects peace processes, this article examines the Colombian peace and justice processes through the lens of friction. It investigates frictional encounters between the Colombian judicial system and the ICC, in order to reveal the tensions in this relationship. First, we disaggregate the concept of friction and propose three
We study the rheological response of dense suspensions of elliptical particles, with an aspect ratio equal to 3, under oscillatory shear flows and imposed pressure by numerical simulations. Like for the isotropic particles, we find that the oscillatory shear flows respect the Cox-Merz rule at large oscillatory strains but differ at low strains, with a lower viscosity than the steady shear and high
The principles of diversity and inclusion are valued across the higher education sector, but the ways in which these principles are translated into pedagogic practice are not always evident. Students who are first in their family to attend university continue to report barriers to full participation in university life. They are more likely to leave their studies early, and to achieve lower grades
Leading change in relation to assessment is a significant challenge; almost everyone in the university is a stakeholder and they may have strong and varied views about how assessment should be managed. A baseline review of assessment practices at a large, diverse, and complex university showed that the prevailing culture around assessment was equivocal and that people were fearful of large-scale c
The early withdrawal of students from healthcare education programmes, particularly nursing, is an international concern and, despite considerable investment, retention rates have remained stagnant. Here, a regional study of healthcare student retention is used as an example to frame the challenge of student attrition using a concept from policy development, wicked problem theory. This approach al
This chapter explores the role of assessment in global citizenship education (GCE). We will consider what can be assessed, and how teachers can design and manage appropriate assignment tasks in relation to normative assessment practices. The ways in which assessment might inform curriculum, behaviours, and engagement with GCE are considered in relation to institutional practices. The role of the a
University policies are increasingly developed with reference to students’ learning experiences, with a focus on the concept of the ‘student voice’. Yet the ‘student voice’ is difficult to define and emphasis is often placed on numerical performance indicators. A diverse student population has wide-ranging educational experiences, which may not be easily captured within the broad categories provid
This chapter examines the role and responsibilities of the individual academic developer and how these reflect the context of the engagement. It considers how different responses to the development context can be identified - not as a prescription designed to treat each individual case, but as a framework for evaluating the need and creating an environment for meeting it successfully. It will make
This paper reflects on the work done at a large UK university to redesign assessment procedures in a way that was intended to contribute to an improvement in assessment literacy for staff. Existing practice was reviewed and showed that changes in assessment processes were needed to make the organization of assessment more consistent and more transparent across the institution and to develop staff
It has become banal to refer to the growth in the use of the Internet in Higher Education (HE). It is now time to regard ‘e-learning’ as an integral part of academic activity, which needs to be routinely supported. This article provides an overview of what is happening and makes some suggestions for organising support services for e-learning.
It can be difficult to engage colleagues with the findings and recommendations of an externally-funded project, even when, or perhaps particularly when, it has major implications for institutional processes. The authors were involved with a large single-institution Higher Education change project that aimed to make the university more responsive to changes in curriculum needs, the student voice, e
We prove Nehari s theorem for integral Hankel and Toeplitz operators on simple convex polytopes in several variables. A special case of the theorem, generalizing the boundedness criterion of the Hankel and Toeplitz operators on the Paley Wiener space, reads as follows. Let = (0, 1)d be a d-dimensional cube, and for a distribution f on 2, consider the Hankel operator f (g)(x) = λ f (x + y)g(y) dy,
Crater-forming events are generally followed by the development of hydrothermal systems due to the rapid heating of the target rock. Such hydrothermal systems are a feature of nearly all large terrestrial impact structures. For the Siljan impact structure in Sweden, there is evidence for such a fossil hydrothermal system, possibly triggered by the impact event ca. 380 Ma. To investigate the therma
Terrorism comes in various forms, clear and sometimes ambiguous, by terrorist cells and sometimes by state players. Nerve agent poisoning represents one of the notorious applications of chemistry in the world. Nerve agents have historically instigated major casualties in various parts, heavily impacting lives of civilians by causing debilitating neurological and psychiatric injuries. Nerve agents
With the risk of climate breakdown becoming ever more pressing as the world is on track for 2.7 degrees warming, pressure is increasing on all sectors of the economy to break with fossil fuel dependence and reduce greenhouse gas (GHG) emissions. In this context, the chemical industry and the production of important basic chemicals is a key sector to consider. Although historically a driver of econ
Background: Transient tachypnoea of the newborn (TTN) is characterised by tachypnoea and signs of respiratory distress. It is caused by delayed clearance of lung fluid at birth. TTN typically appears within the first two hours of life in term and late preterm newborns. Although it is usually a self-limited condition, admission to a neonatal unit is frequently required for monitoring, the provision
In this work we measured, by using a direct approach, the equilibrium solubility of recombinant Aβ40 peptide to be S = 0.36 ± 0.15 μM in aqueous solution of 20 mM sodium phosphate buffer at pH 7.4. Microfluidic diffusional sizing (MDS) and mass spectrometry (MALDI-TOF/TOF) with isotope standard were used to quantify the concentration of soluble Aβ40 species coexisting with formed fibrils. A
Elevated maternal glucocorticoid levels during gestation can lead to phenotypic changes in offspring via maternal effects. Although such effects have traditionally been considered maladaptive, maternally derived glucocorticoids may adaptively prepare offspring for their future environment depending upon the correlation between maternal and offspring environments. Nevertheless, relatively few studi
