Choosing conflict on the road to sustainable mobility : A risky strategy for breaking path dependency in urban policy making

Previous studies have identified implementation problems connected to sustainable mobility. These difficulties raise the question of which strategies can be successfully pursued to break path dependencies in urban policy making. This article is focused on corporate mobility management as one specific example of sustainable mobility initiatives, and analyses the formation and implementation of a tr

The politics of speed – Local and regional actors’ views on speed limits, traffic safety and mobility in Sweden

Background and aim In most European countries, the often difficult policy process of setting and implementing speed limits on specific roads is delegated to public administration on local and regional levels. The purpose of this paper is to describe and analyze the perspectives and priorities of regional actors, specifically planners and elected officials within public administration, concerning t

Being a ‘strategist’ : Communication practitioners, ‘strategic work’, and power effects of the strategy discourse

PurposeThe paper analyzes power effects of the strategy discourse to create a more profound understanding of how strategy seen as a discourse constitutes certain identities and practices among communication practitioners. The following two research questions has been posed to concretize the overall aim of the study: 1) What has the strategy discourse meant for practitioners understanding of themse

The impact of relaxed traveller allowances: Fixed-effects analyses of the associations between consumer behaviour and alcohol use

Aim: To analyse to what extent the gradual relaxation of traveller allowances for alcoholic beverages 2001–2004 changed consumer behaviours and subsequent alcohol consumption patterns within a longitudinal panel data population study in Southern Sweden. Methods: General population random sample panel data study with repeated measurements were collected in 1999, in 2005, and in 2010 in the county

Bivariate genome-wide association study of depressive symptoms with type 2 diabetes and quantitative glycemic traits

Objective: Shared genetic background may explain phenotypic associations between depression and Type 2 diabetes (T2D). We aimed to study, on a genome-wide level, if genetic correlation and pleiotropic loci exist between depressive symptoms and T2D or glycemic traits. Methods: We estimated single-nucleotide polymorphism (SNP)-based heritability and analyzed genetic correlation between depressive sy

Neuroblastoma with flat genomic profile : A question of representativity?

Neuroblastoma is one of the most common paediatric malignancies. Detection of somatic genetic alterations in this tumour is instrumental for its risk stratification and treatment. On the other hand, an absence of detected chromosomal imbalances in neuroblastoma biopsies is difficult to interpret because it is unclear whether this situation truly reflects the tumour genome or if it is due to subopt

Kylbehandling efter förlossningsasfyxi minskar skadeutveckling : Barn med cerebral pares får bättre funktion, visar retrospektiv genomgång i kvalitetsregistret CPUP

Hypothermic treatment after birth asphyxia was introduced as a recommended practice in Sweden in 2007. CPUP is a national quality register and surveillance program that encompasses the total population of children with cerebral palsy (CP) in Sweden. In an analysis of CPUP data children with CP and asphyxia treated with cooling were compared to children with CP and asphyxia who were not cooled. A l

Fluid deficits during prolonged overnight fasting in young healthy adults

Background: Overnight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2-2.0 mL·kg−1·h−1, but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss d

Re-inforcing the cell death army in the fight against breast cancer

Metastatic breast cancer is responsible for most breast cancer-related deaths. Disseminated cancer cells have developed an intrinsic ability to resist anchorage-dependent apoptosis (anoikis). Anoikis is caused by the absence of cellular adhesion, a process that underpins lumen formation and maintenance during mammary gland development and homeostasis. In healthy cells, anoikis is mostly governed b

Continuous Model Validation using Reference Attribute Grammars

Just like current software systems, models are characterised by increasing complexity and rate of change. Yet, these models only become useful if they can be continuously evaluated and validated. To achieve sufficiently low response times for large models, incremental analysis is required. Reference Attribute Grammars (RAGs) offer mechanisms to perform an incremental analysis efficiently using dyn

Identifying bacteria using DNA binding maps

We have developed an assay, based on nanofluidic channels and fluorescence microscopy, for optical mapping of DNA based on competitive binding between two molecules - one fluorescent and one sequence selective. From the experimental data we can extract binding constants for the two competing DNA binders, which may be subsequently used to calculate a theoretical reference map of any DNA with known

Separation of deformable hydrogel microparticles in deterministic lateral displacement devices

To better understand how deformable and non-spherical particles behave in sorting devices based on deterministic lateral displacement we generate models of biological particles with tunable size, shape and mechanical properties using stop-flow lithography and we explore how these parameters play a role in our separation devices. Hollow and solid cylinders are compared with respect to their deforma

Meandering nanochannels for imaging of ultra-long DNA molecules

A new chip design for handling and studying chromosomal DNA is described. Folding the nanochannels enables us to image an entire yeast chromosome in a single field of view. Together with existing mapping techniques our new design opens up the possibility of directly analyzing entire chromosomes in a single field of view using fluorescence microscopy. This would enable, for example, identification

Chimpanzees like to copy human visitors to the zoo - Ig Nobel prize

How good is your best chimpanzee impression? Go to the zoo and you probably wouldn’t be surprised to see people copying chimpanzees in order to grab their attention. But our latest research, which recently won the Ig Nobel Prize for Anthropology, suggests you are just as likely to see chimpanzees imitating the human visitors.

Morphology-based sorting-blood cells and parasites

Morphology represents a hitherto unexploited source of specificity in microfluidic particle separation and may serve as the basis for label-free particle fractionation. There is a wealth of morphological changes in blood cells due to a wide range of clinical conditions, diseases, medication and other factors. Also, blood-borne parasites differ in morphology from blood cells. We present the use of

Throughput through thin-film fluidics

We demonstrate fluidics realized in thin film plastic foils patterned using roll-toroll nanoimprinting lithography (rrNIL). Realizing fluidics devices in thin plastic foils opens up for parallel operation in stacked devices. It also provides a convenient format for storage and distribution of the devices.

Tipping the balance with dielectrophoretic forces - An electric deterministic lateral displacement device

We present experimental results and simulations on a simple method for tunable particle separation based on a combination of Deterministic Lateral Displacement (DLD) and Insulator Based Dielectrophoresis (I-DEP). Rather than deriving its tunability from its elastic properties[1], our present device uses an applied AC field to perturb the particle trajectories in the pressure-driven flow and is the
