This paper discusses methods to test the performance of the adaptation layer in a self-adaptive system. The problem is notoriously hard, due to the high degree of uncertainty and variability inherent in an adaptive software application. In particular, providing any type of formal guarantee for this problem is extremely difficult. In this paper we propose the use of a rigorous probabilistic approac

Objective: To assess which structural abnormalities on knee MRI are associated with development of osteophytes in middle-aged subjects without radiographic knee osteoarthritis. Design: We included subjects from the Osteoarthritis Initiative, aged 40–55 years, Kellgren & Lawrence grade 0 in both knees, and knee MRIs from both knees available at baseline, 24, 48 and 72 months. Structural exposur

The high cycle fatigue behaviour of autoclave-cured carbon fibre-reinforced polymer (CFRP) composite gears is investigated. The CFRP gears were milled from a composite plate and tested in mesh with a steel drive gear under five torque loads ranging between 0.4 and 0.8 Nm in unlubricated conditions. A detailed gear damage analysis is conducted by employing scanning electron microscopy and high-reso

This special issue follows on from a special call for contributions tothe ECER 2016 conference in Dublin on the need to rethink andreconceptualise internationalisation in higher education (HE). Thepapers in this special issue contribute to a critically reflectiveinterdisciplinary discussion on the phenomena ofinternationalisation in terms of the evolution of the structures,systems, and functions o

The purpose of this thesis is to add an astronomical component to the history and evolution of Earth by reconstructing the micrometeorite flux to Earth at different time intervals during the Phanerozoic Eon, using sediment-dispersed extraterrestrial spinel group minerals as a proxy. Chromite and chrome spinel are common refractory members of the spinel group, occurring in both extraterrestrial and

Introduction: Antimicrobial resistance (AMR) is a global public health threat. Worse still, there is a paucity of data from low-and middle-income countries to inform rational antibiotic use. Objective: Assess the feasibility of setting up microbiology capacity for AMR testing and estimate the cost of setting up microbiology testing capacity at rural district hospitals in Rwanda. Methods: Laborator

Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anoma

Sweden is actively seeking to scale up repair activities as part of its strategy to reduce waste, transition to a circular economy, and achieve zero net emissions by 2045. In the last couple of years, several new policies to promote consumer repairs have been adopted or proposed in Sweden. However, very little is known about the socio-cultural factors that shape people's decision to repair their p

Extending the lifetime of products is seen as a key objective for realising the vision of a Circular Economy. One way to increase the lifespan of products is to enable more repair activities. However, consumers encounter a variety of barriers for repairs, prompting public authorities in Europe and the US to adopt or propose policies in support of consumer repairs. Sweden has recently adopted a cir

ObjectivesThe objectives of this study are threefold: first, we separate trust into a two-dimensional concept: ingroup trust and outgroup trust. Second, we apply both types of trust to two dependent variables: nativism and civicness, hypothesizing that respondents with ingroup trust should display higher degrees of nativism and lower degrees of civicness while the opposite should apply to responde

Expert surveys are a valuable, commonly used instrument to measure party positions. Some critics question the cross-national comparability of these measures, though, suggesting that experts may lack a common anchor for fundamental concepts such as economic left–right. Using anchoring vignettes in the 2010 Chapel Hill Expert Survey, we examine the extent of cross-national difference in expert ideol

In this article, we combine advances in both survey research and scaling techniques to estimate a common dimension for political parties across the member states of the European Union. Most previous scholarship has either ignored or assumed cross-national comparability of party placements across a variety of dimensions. The 2010 wave of the Chapel Hill Expert Survey includes anchoring vignettes wh

ObjectiveThis article explores whether there is a systematic variation in conventional and unconventional political participation as a function of in-group versus out-group trust. We postulate that the narrower the moral community is, the more political participation is restricted to conventional activity that is perceived as an obligation, as a political act to be fulfilled, something akin to cit

This article reports on the 2010 Chapel Hill expert surveys (CHES) and introduces the CHES trend file, which contains measures of national party positioning on European integration, ideology and several European Union (EU) and non-EU policies for 1999−2010. We examine the reliability of expert judgments and cross-validate the 2010 CHES data with data from the Comparative Manifesto Project and the

Party members across European democracies exercise increasing influence on parties’ policy platforms or personnel choices. This article investigates ideological (in)congruence on the left–right spectrum between members and their parties by drawing on a party membership survey of more than 10,000 individuals across seven political parties in Sweden. The results show that around two-thirds of member

Party competition in Eastern Europe faces a seeming paradox. On the one hand, research finds increased political volatility in these countries, while, on the other, some authors demonstrate inherent ideological stability in the region. This research note presents a new methodological approach to adjudicating between these two findings, and suggests that while political organisations come and go, t

This article addresses the variation of anti-corruption and anti-elite salience in party positioning across Europe. It demonstrates that while anti-corruption salience is primarily related to the (regional) context in which a party operates, anti-elite salience is primarily a function of party ideology. Extreme left and extreme conservative (TAN) parties are significantly more likely to emphasize
