A Focus on Critical Thinking or Linguistic Features?

The aim of the study is to research upper secondary teachers’ attitudes towards, and use of, critical perspectives in teaching literature in the subject of English in Sweden. This is done in relation to the inequality issues identified in the Swedish school context, the Swedish National Curriculum for the Upper Secondary School and the syllabi for English, along with a theoretical framework based

Using scenarios to balance future requirements and capability development

Title: Using scenarios to balance future requirements and capability development Author: Erik Jacobsson Division: Production Management Supervisors: Bertil Nilsson at the Technical Faculty of Lund University, Innovation Advisor at the case company Keywords: Scenarios, Corporate development, Energy Sector, Capabilities, Technology Background: The speed of change in the world is ever increasing

500 000-year-old basal ice at Skytrain Ice Rise, West Antarctica, estimated with the 36Cl/10Be ratio

Dating the bottommost section of an ice core is often complicated by strong layer thinning and possible disturbances in the stratigraphy. The radioactive decay of atmospherically produced 36Cl and 10Be can provide age estimates, where traditional methods can no longer be used. In this study, we investigated ice from the bottom of the Skytrain ice core, which was drilled in West Antarctica next to

Dating Ice Cores with the 36Cl/10Be Ratio

Ice cores are unique archives of paleo-climate information and require accurate dating for its interpretation. Continuous chronologies are usually based on time markers, stratigraphic matching, and orbital tuning, but often end several meters above bedrock, because extreme thinning and sometimes disturbances in the stratigraphy complicate the identification of climate signals and their alignment w

Controlled exposure to particulate matter from urban street air is associated with decreased vasodilation and heart rate variability in overweight and older adults

Background: Exposure to particulate matter (PM) is generally associated with elevated risk of cardiovascular morbidity and mortality. Elderly and obese subjects may be particularly susceptible, although short-term effects are poorly described. Methods: Sixty healthy subjects 25 males, 35 females, age 55 to 83 years, body mass index > 25 kg/m(2)) were included in a cross-over study with 5 hours of

Advert saliency distracts children's visual attention during goal-directed internet use

The general research question of the present study was to assess the impact of visually salient online adverts on children's task-oriented internet use. In order to answer this question as reliably as possible, an experimental study was constructed in which 9-year-old and 12-year-old Swedish children were asked to solve a number of tasks while interacting with a mockup website. In each trial, web

Random self-decomposability and autoregressive processes

We introduce the notion of random self-decomposability and discuss its relation to the concepts of self-decomposability and geometric infinite divisibility. We present its connection with time series autoregressive schemes with a regression coefficient that randomly turns on and off. In particular, we provide a characterization of random self-decomposability as well as that of marginal distributio

Self-aware computing in the Angstrom processor

Addressing the challenges of extreme scale computing re- quires holistic design of new programming models and sys- tems that support those models. This paper discusses the Angstrom processor, which is designed to support a new Self-aware Computing (SEEC) model. In SEEC, applications explicitly state goals, while other systems components provide actions that the SEEC runtime system can use to meet

A lightweight data interchange format for Internet of Things in the PalCom middleware framework.

We present the PalCom Object Notation, a textual data representation format for communication between internet of things which support binary and textual data. The format does not require parsing of user data (or the “payload”) and is thus efficient to use also for large binary values such as digital images, audio and video as well as for short textual values. These can be mixed in the same messag

A literature review of agile practices and their effects in scientific software development

The nature of scientific research and the development of scientific software have similarities with processes that follow the agile manifesto: responsiveness to change and collaboration are of the utmost importance. But how well do current scientific software development processes match the practices found in agile development methods, and what are the effects of using agile practices in such proc

Using PCA and Global Smoothing to Explore Differences between Global Vegetation Models

A common method for comparing the result of different global circulation models (GCMs) under different emission scenarios is to study global climate response variables, such as mean temperature. An interesting alternative measure of climate sensitivity is to study the biosphere’s response to the different climate scenarios. The Lund-Postdam-Jena (LPJ) global vegetation model and its extension LPJ-

Cryptanalysis of the Stream cipher BEAN

BEAN is a recent stream cipher proposal that uses Feedback with Carry Shift Registers (FCSRs) and an output function. There is a sound motivation behind the use of FCSRs in BEAN as they provide several cryptographically interesting properties. In this paper, we show that the output function is not optimal. We give an efficient distinguisher and a key recovery attack that is slightly better than brut

Stochastic Models Involving Second Order Lévy Motions

This thesis is based on five papers (A-E) treating estimation methods for unbounded densities, random fields generated by Lévy processes, behavior of Lévy processes at level crossings, and a Markov random field mixtures of multivariate Gaussian fields. In Paper A we propose an estimator of the location parameter for a density that is unbounded at the mode. The estimator maximizes a modified lik

Flow Adjustment - a Flexible Routing Strategy for Demand Protection Against Multiple Partial Link Failures

In this paper, we study a flexible routing strategy for demand protection and a corresponding optimization problem for networks that permanently experience fluctuations of the capacity available on their links. This is an important and novel topic as limited link availability is a fundamental feature of wireless networks; yet majority of work in survivable network design is restricted to total fai
