Towards understanding learning challenges involving sign convention in introductory level kinematics

Coming to appropriately appreciate the meaning of algebraic signs is an important aspect in introductory kinematics. However, in this educational context, the “disciplinary relevant aspects“ of algebraic signs across vector and scalar representations are extremely difficult to discern. Our study explores the “relevance structure“ that one-dimensional kinematics problems evoked for introductory lev

An action research approach to developing, implementing and evaluating methods for risk and vulnerability assessment

Development of methods for Risk and Vulnerability Assessment (RVA) is typically carried out more or less isolated from the practical context in which the method is intended to be used. This means that practical limitations, constraints and challenges are missed, potentially leading to the proposed method is not suited for its intended end-users and giving poor results. Therefore, the aim of this p

Effects of low thinning on carbon dioxide fluxes in a mixed hemiboreal forest

We used eddy-covariance (EC) measurements of net ecosystem exchange (NEE) above canopy to assess the effects of thinning on CO2 fluxes at the ICOS Sweden site Norunda in central Sweden. This forest site consists of mixed pine and spruce stands approx. 100 years old. The thinning during late autumn 2008, performed in a semicircle from the mast extending 200m outwards harvested about 25% of the volu

Young adult audiences, news, and news satire : A double-voiced engagement

Young adult audiences, news, and news satire: A double-voiced engagementDuring the past decades, news satire has become increasingly popular in many parts of the world (Baym & Jones 2013), while more traditional news genres – in print and broadcast media – seem to be losing some of its young adult audience (cf. Wadbring 2016). Additionally, in the contemporary media landscape, audiences engage

The Salt-Inducible Kinases : Emerging Metabolic Regulators

The discovery of liver kinase B1 (LKB1) as an upstream kinase for AMP-activated protein kinase (AMPK) led to the identification of several related kinases that also rely on LKB1 for their catalytic activity. Among these, the salt-inducible kinases (SIKs) have emerged as key regulators of metabolism. Unlike AMPK, SIKs do not respond to nucleotides, but their function is regulated by extracellular s

How are biodiversity and dispersal of species affected by the management of roadsides? A systematic map

Background: In many parts of the world, roadsides are regularly managed for traffic-safety reasons. Hence, there are similarities between roadsides and certain other managed habitats, such as wooded pastures and mown or grazed grasslands. These habitats have declined rapidly in Europe during the last century. For many species historically associated with them, roadsides may function as new primary

Standards, Barriers to Trade and EU Internal Market Rules : Need for a Renewed Approach?

In light of the speedy technological development in society, technical standards are becoming increasingly important. In the early days, the specific tasks delegated to standardization bodies under the New Approach did not attract much political interest. Today, however, politicians and different stakeholders realize that the tasks delegated to the standardization industry are highly important for

Spain: an extreme case of successful integration of second-generation immigrants with transfers of best practices applicable to other European countries?

This volume presents cutting-edge research on integration and adaptation processes of second-generation immigrant adolescents in Spain that no doubt constitutes an important and timely contribution to the migration-integration debate. Principal findings of the Investigación Longitudinal de la Segunda Generación study indicate a comparatively smooth integration of second-generation immigrant adoles

LONG-TERM MODELLING OF AEOLIAN TRANSPORT AND BEACH-DUNE EVOLUTION

A model to simulate long-term beach-dune evolution due to interacting longshore and cross-shore sediment transport processes is developed and tested. The work builds on a cross-shore model (CSM) previously developed at Lund University and includes changes to the equations describing aeolian transport and morphological evolution. The modifications are mainly based on existing conceptual geomorpholo

Educational Assortative Mating and Household Division of Labor : A pan-European Perspective

Educational homogamy has been increasing for a long time in the Western world but there has been much more research on describing and explaining this trend than actually looking at its consequences. Economic theory predicts that educational heterogamy is related to division of labor in accordance with comparative advantages in household and market production, but there has been few tests of this h

Circadian repressors CRY1 and CRY2 broadly interact with nuclear receptors and modulate transcriptional activity

Nuclear hormone receptors (NRs) regulate physiology by sensing lipophilic ligands and adapting cellular transcription appropriately. A growing understanding of the impact of circadian clocks on mammalian transcription has sparked interest in the interregulation of transcriptional programs. Mammalian clocks are based on a transcriptional feedback loop featuring the transcriptional activators circad
