In this article, we re‐visit a recent idea of Phillips and Lee (2015. Econometric Reviews 34: 1035 ‐ 1056). They examine an empirically relevant situation when two time series exhibit different degrees of non‐stationarity and one need to learn whether their persistence properties are the same. By bridging the asymptotic theory of local to unity and mildly explosive processes, they construct a Wald

Coronapandemin har inneburit ett hårt slag för café- och restaurangbranschen då kunderna i stor utsträckning uteblir, dels på grund av rädsla för smitta, dels på grund av uppmaningar från myndigheterna om social distansering. I branschen ärmånga småföretagare utan större ekonomisk buffert. Innan krisen är över kommer sannolikt många företag att ha tvingats lägga ned verksamheter (DN, 2020). Vi för
Anmeldelse af Achim Heschers Reading Graphic Novels.
There is an increasing expectation from research funding bodies that projects in working life and policy research (and other fields) should demonstrate clear and demonstrable impacts on policy and practice. In turn, many also argue that impact, beyond scientific impact, can be leveraged by stakeholder engagement. But what do we mean by stakeholder engagement in the conduct of working life research?
The aim of the study presented in this report was to investigate what cues cyclists use to interpret the intention of motor vehicles (MVs) they interact with. This was done with help of on-site observations of cyclists’ interactions with motor vehicles (MV) at signalised intersections with different bicycle infrastructure facilities: A) no dedicated cycle facility, B) cycle lane and C) cycle path.The aim of the study presented in this report was to investigate what cues cyclists use to interpret the intention of motor vehicles (MVs) they interact with.

Kollektivtrafiken är en viktig del i omställningen till ett mer miljömässigt hållbart resande. De alltmer marknads- och kundorienterade regionala kollektivtrafikmyndigheterna marknadsför sig idag med en mängd budskap i en växande flora av kanaler som direktutskick, hemsidor och appar. Denna kommunikation och marknadsföring är en del av den påverkan som resenären har att förhålla sig till i ett all
The aim of the project was to examine interactions between motor vehicle drivers and cyclists at intersections and the impact of infrastructure design and motor vehicle characteristics on interactive behaviour. The project activities included literature reviews on cycling infrastructure at intersections, vehicle driver behaviour and cyclist behaviour; questionnaires among motor vehicle drivers andThe aim of the project was to examine interactions between motor vehicle drivers and cyclists at intersections and the impact of infrastructure design and motor vehicle characteristics on interactive behaviour.

Popular Abstract in Swedish Frågan om Amerikas kulturella ställning i förhållande till den övriga världen är av central betydelse för all forskning som berör Amerikas och det moderna Europas historia. Det här förhållandet har blivit påtagligare under senare tid beroende av vårt samhälles senare "kris" med det s. k. "postmoderna" - och "globaliserade" - perspektivets genombrott. I avhandlingen presThe question of America’s cultural position in relation to the rest of the world is essential for all research connected to America and to the history of modern Europe. This situation has become obvious over the last years because of our societies’ latest “crisis”, with the consecration of the “post-modern” and “global” view of society, history and culture. The aim of the dissertation is to analys
The edge strength of glass is analyzed using a Weibull statistical framework based on 78 data samples from a range of experiments recorded in literature. Based on the analysis, a 45 MPa strength value (computed as the lower bound in a one-sided confidence interval at the 75% level for the 5-percentile in the distribution) could be conservatively used with arrised, ground and polished edges when re
The idea of employees as important (strategic) communicators has emerged in both strategic communication theory and practice during the 21st century. Researchers increasingly urge managers to consider employees as important communicators, and employees’ communication role is increasingly formalized as organizations explicate the importance of all employees taking responsibility for communication i
En främre korsbandsskada i knät är vanligt förekommande bland fysiskt aktiva personer inom sporter som innehåller vridningar, inbromsningar och snabba riktningsförändringar, såsom handboll och fotboll. Skadan kan exempelvis leda till en instabil knäled, försämrad funktion i vardagliga och idrottspecifika aktiviteter, försvagade lårmuskler, försämrad rörelsekvalité och nedsatt självskattad funktionRupture of the anterior cruciate ligament (ACL) is a common knee injury among young physically active populations. The injury results in impaired physical functions, such as joint instability, limitations in daily activities and sport-specific activities, and worse movement quality, e.g., altered postural orientation. Postural orientation is defined as the ability to maintain alignment between bod
Background and study aims : Capsule endoscopy (CE) is invaluable for minimally invasive endoscopy of the gastrointestinal tract; however, several technological limitations remain including lack of reliable lesion localization. We present an approach to 3D reconstruction and localization using visual information from 2D CE images.Patients and methods : Colored thumbtacks were secured in rows to the
