Purpose: Insomnia affects up to one in four adolescents and has been shown to have a negative impact on their mental and physical health. This study aimed to investigate the association between insomnia, academic performance, self-reported health, physical activity, school start time, and substance use among adolescents. Methods: A survey with a cross-sectional design was completed by adolescents

This introductory chapter provides an overview of seaweed biorefinery opportunities, providing basis for multiple value chains, contributing to nutrition and health of a growing global population, to local job generation and development, to ecosystem services, and not the least to climate change mitigation and adaptation. A unique and rich diversity of the seaweed components provides the basis for

Although there has been a long tradition of public space-related land speculation and development, the recent success of the High Line in New York has highlighted the transformative effect carefully designed and curated public spaces can have on the local economy. By prioritising exchange value over use value, governments and developers are exploiting the production of public spaces as a means for

The detections of 1I/‘Oumuamua and 2I/Borisov within just two years of each other impressively demonstrate that interstellar objects (ISOs) must be common in the Milky Way. Once released from their parent system, these ISOs travel for billions of years through interstellar space. While often imagined as empty, interstellar space contains gas and dust most prominent in the form of molecular clouds.

Nanoscale X-ray detectors could allow higher resolution in imaging and diffraction experiments than established systems but are difficult to design due to the long absorption length of X-rays. Here, we demonstrate X-ray detection in a single nanowire in which the nanowire axis is parallel to the optical axis. In this geometry, X-ray absorption can occur along the nanowire length, while the spatial

We use semi-grand canonical Monte Carlo simulations to study an electrolytic capacitor with an adsorbed peptide on the electrode surfaces. Only homogeneous peptides are considered, consisting of only a single residue type. We find that the classical double-hump camel-shaped differential capacitance in such systems is augmented by the addition of a third peak, due to the capacitance contribution of

BACKGROUND: Continuous spike-wave during slow wave sleep syndrome (CSWS) and Landau-Kleffner syndrome (LKS) are two epileptic encephalopathies that present with neurocognitive regression, aphasia, and clinical seizures, typically presenting in children around five years of age. The pathophysiology of these conditions is not completely understood. Some studies suggest a common origin for both. No s

Let S(Λ) denote the classical Littlewood–Paley operator formed with respect to a lacunary sequence Λ of positive integers. Motivated by a remark of Pichorides, we obtain sharp asymptotic estimates of the behaviour of the operator norm of S(Λ) from the analytic Hardy space HAp(T) to Lp(T) and of the behaviour of the Lp(T) → Lp(T) operator norm of S(Λ) (1 < p< 2) in terms of the ratio of the lacunar

It is known that for Kn,n equipped with i.i.d. exp (1) edge costs, the minimum total cost of a perfect matching converges to in probability. Similar convergence has been established for all edge cost distributions of pseudo-dimension . In this paper we extend those results to all real positive q, confirming the Mézard-Parisi conjecture in the last remaining applicable case.

Universal Design (UD) is a design approach that recognises and anticipates diversity as a fundamental human condition. UD is also frequently referred to in relation to the social dimension of sustainable development. Central to both UD and sustainability is the way “everyone,” as the target of UD and sustainability goals, is understood. The purpose of the study is to identify how UD’s “everyone” i

För att hantera samhällets globala och mest komplexa utmaningar krävs ofta en nära samverkan mellan forskning och samhälle, ibland även kallat ett akademiskt engagemang. Frågan är vilka former denna samverkan ska ta, om forskningen även ska nå fram till politiska beslutsfattare. Detta kapitel har redogjort för hur samverkan mellan den statliga kommittén Tillitsdelegationen och akademin organiserad

Lunds universitet har anmodats att ge synpunkter på rubricerad remiss. Lunds universitet konstaterar att promemorian inte uppfyller de mest elementära krav på samhällsekonomisk analys som kan ställas på en offentlig utredning. Slutsatserna sakar tydligt stöd i ekonomisk teori och empiri.

In the wake of global crises concerning, for example, inequalities, migration, pandemics, and the environment, ethical concerns have come to the fore. In this thematic issue, we are especially interested in the role that the planning, design, and materialities of the built environment can take in relation to ethics, and we present four different openings or themes into urban ethics that we also th

This article aims to understand how the introduction of blue-green solutions affects ethical concerns and expectations of an urban environment. Blue-green solutions are complementary technical solutions, introduced into urban water management, in order to deal with the impact of urbanisation and climate change. These kinds of solutions establish new affordances that have an impact on everyday life
