Plants effective against insomnia and sleep apnea

Insomnia and sleep apnea represent the most prevalent sleep disorders worldwide. Incidences are discouraging, with perhaps less attention in some parts, and the complexity in the pathophysiologies of the two diseases pose a major challenge to clinicians and researchers. Mainstream therapeutic regimens are afflicted by adverse side effects, laborious, demanding enormous amounts of money, and are in

Lead

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

Friction in Transitional Justice Processes : The Colombian Judicial System and the ICC

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

Orientational arrest in dense suspensions of elliptical particles under oscillatory shear flows

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

Shape-shifting and pushing against the odds : staff perceptions of the experiences of first generation students in South Africa and the UK

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

Myths and legends : Changing assessment procedures and practices

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 wicked problem of healthcare student attrition

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

Global citizenship education-Assessing the unassessable?

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

The potential of student narratives to enhance quality in higher education

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

Identifying needs and opportunities for academic development

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

Supporting the development of assessment literacy of staff through institutional process change

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

Supporting e-learning : an overview of the needs of users

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.

Accreditation! the responsive curriculum game

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

Nehari's Theorem for Convex Domain Hankel and Toeplitz Operators in Several Variables

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,

40Ar/39Ar age evidence for an impact-generated hydrothermal system in the Devonian Siljan crater, Sweden

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

Applications of phytochemicals against nerve agents in counterterrorism

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

Petrochemicals and Climate Change : Tracing Globally Growing Emissions and Key Blind Spots in a Fossil-Based Industry

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

Interventions for the management of transient tachypnoea of the newborn - an overview of systematic reviews

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
