Group work is increasingly used in higher education and is associated with several benefits, both for the students and the teacher. How groups are assigned is of significance for the success of group work. This study aspires to explore the ways in which teachers can assign groups in order to enable successful group work. The findings indicate that heterogeneous groups that consist of students with

We present an approach for the estimation of ore processing residue volumes in historical mine waste dumps by the use of different geophysical methods in combination with mineralogical investigations. The stamp mill dump in the Harz mountains, Germany was examined with the methods electrical resistivity tomography (ERT), ground penetrating radar (GPR) and spectral induced polarization (SIP) flanke

Tandläkare och tandhygienister graderar beprövad och personlig erfarenhet som bas för sunt beslutsfattande högre än de som jobbar inom hälso- och sjukvården. Varför det är så är inte enkelt att besvara, men det är rimligt att anta att tandläkarnas syn på beprövad och personlig erfarenhet påverkas av rådande kunskapsläge, den organisation inom vilken de verkar samt gällande lagar och förordningar.

Greater Copenhagen is often cited as a good example of cross-border cooperation. Shared historical contexts and socio-political willingness have meant that considerable resources have been invested into the development of infrastructure in this region. The Öresund fixed link constitutes the most important element of this infrastructure, facilitating a cross-border public transport system which tie

Aim: The present study investigates the effect of signal degradation on perceived listening effort in children with hearing loss listening in a simulated class-room context. It also examines the associations between perceived listening effort, passage comprehension performance and executive functioning. Methods: Twenty-four children (aged 06:03–13:00 years) with hearing impairment using cochlear i

In the search for renewable fuels, there are very few candidates as compelling as methanol. It can be derived from refuse material and industrial waste, while the infrastructure exists worldwide to support broad and fast adoption, potentially even as a "drop-in" fuel for existing vehicles with only minor modifications. The most efficient engines currently available are compression-ignition engines

Few revolutions have had such an impact in modern times as the Cuban Revolution in 1959. Numerous publications (books, articles, and dissertations) have been written about it. Opinions about it have diverged. The revolution has been an inspiration for many, contested and even detested by others. In 1961, the Cuban Revolution took a radical turn when Fidel Castro declared that the revolution was so

Automatic recognition of an online series of unsegmented actions requires a method for segmentation that determines when an action starts and when it ends. In this paper, a novel approach for recognizing unsegmented actions in online test experiments is proposed. The method uses self-organizing neural networks to build a three-layer cognitive architecture. The unique features of an action sequence

Democracy’s normative foundation is political equality. Yet the dominance of the elite over the masses, and the systematic exclusion of particular social and economic groups from the influence on, and outcomes of, important decisions, manifests in political inequality. If this situation is normatively intolerable, why does political inequality endure? We build on the theoretical and empirical lite

Introduction: The prevalence of arthropathy in moderate haemophilia A (MHA) and B (MHB) is not well known. Aim: We evaluated joint health in Nordic patients in relation to their treatment modality. Methods: A cross-sectional, multicentre study covering MHA and MHB in Sweden, Finland and Norway. Arthropathy was evaluated by ultrasound (HEAD-US) and Haemophilia Joint Health Score (HJHS). Results: We

We determine which sets saturate the Szegő and Schiefermayr lower bounds on the norms of Chebyshev Polynomials. We also discuss sets that saturate our optimal Totik–Widom upper bound.

Does education change people’s lives in a way that delays mortality? Or is education primarily a proxy for unobserved endowments that promote longevity? Most scholars conclude that the former is true, but recent evidence based on Danish twin data calls this conclusion into question. Unfortunately, these potentially field-changing findings—that obtaining additional schooling has no independent effe

Background: Prenatal exposures may contribute to male infertility in adult life, but large-scale epidemiological evidence is still lacking. The Fetal Programming of Semen quality (FEPOS) cohort was founded to provide means to examine if fetal exposures can interfere with fetal reproductive development and ultimately lead to reduced semen quality and reproductive hormone imbalances in young adult m

Guided by the social model of disability, we carried out this exploratory study to understand the health and psychosocial needs of women living in social housing in Ontario, Canada. Using a sequential, mixed-methods design, we interviewed 19 women using a 126-item quantitative interview including six standardized measures exploring indicators of psychosocial well-being. From these findings, we des

Unlike virtual chromoendoscopy-assisted capsule endoscopy, “tinted capsule endoscopy” aims at using a tinted optical dome and/or LEDs in the effort to enhance the detection and characterization of pathologies in capsule endoscopy images.

Tropical America is currently experiencing the establishment of a new apex insect predator, the Paleotropical dragonfly Hemianax ephippiger (Odonata: Aeshnidae). H. ephippiger is migratory and is suggested to have colonised the eastern Neotropics by chance Trans-Atlantic displacement. We report the discovery of H. ephippiger at three new locations in the Caribbean, the islands of Bonaire, Isla de

Aims: To compare the bioactivity of circulating microparticles (MPs) isolated from dyslipidemic Psammomys obesus (P. obesus) fed a high-energy diet (HED) with those released from healthy P. obesus fed a normal diet (ND). Methods: Vascular reactivity of aortic rings was evaluated by myography, after 24 h incubation in the absence or in the presence of circulating MPs isolated, by differential centr
