In this paper we study the computational complexity of the extended minimum cost homomorphism problem (Min-Cost-Hom) as a function of a constraint language, i.e. a set of constraint relations and cost functions that are allowed to appear in instances. A wide range of natural combinatorial optimisation problems can be expressed as extended Min-Cost-Homs and a classification of their complexity would be highly desirable, both from a direct, applied point of view as well as from...
A confined masonry (CM) structure comprises load-bearing masonry walls and confining elements located at the perimeter of wall panels. These confining elements are generally small cast-in-place RC tie-beams and tie-columns. The distinctive feature of CM construction from a regular masonry infill RC frame is that the masonry is constructed prior to the casting of confining elements. Such construction has evolved based on the satisfactory performance in past earthquakes. Though commonly recognized as an effective practice,...
New generic top-level domain names (gTLDs) are the highest level of domain names in the domain name system (DNS); their number has been restricted to twenty-two for several years, and ICANN has implemented restrictions on the ways in which they are operated. The new gTLD programme, proposed by the Internet Corporation for Assigned Names and Numbers (ICANN) in early 2013, enables businesses and organisations to apply for their own customised top-level domain names, thereby greatly...
German Survey on Volunteering 1999. English Version: Documentation of the Design and Instrument of the Second Wave of the German Survey on Volunteering (FWS 1999)Claudia Vogel, Thomas Gensicke & Katharina Lux
The German Survey on Volunteering (FWS) is a representative survey of voluntary activities of persons aged 14 and older in Germany. Volunteering and the willingness to volunteer can be reported and described among population groups and across regions. Additionally, volunteers as well as former volunteers and other persons who do not volunteer can be studied. The FWS provides a substantial database for the description of volunteering in Germany and is funded by the Federal Ministry...

miRNAs are small RNAs that guide Argonaute proteins to target mRNAs through perfect complementarity involving 7-8 nucleotides of the miRNA's 5'end. These 'canonical' targets typically undergo degradation and translational inhibition. However, recent studies have suggested that miRNA target degradation can give rise to additional behaviors. These unclude the threshold-linear response of the targets to their transcriptional induction, reduction of the 'noise' in target expression and induction of correlations in the expression of the targets of...

Dalla Francia all'Italia: impegno politico, inchiesta e transfers culturali alle origini della sociologia del lavoro in ItaliaFranco, Daniele <1980>
Sociology of work in Italy revived at the end of WWII, after thirty years of forced oblivion. This thesis examines the history of discipline by considering three paths that it followed from its revival up to its institutionalization: the influence of the productivity drive, the role of trade unions and the activity of early young researchers. European Productivity Agency's Italian office Comitato Nazionale per la ProduttivitÃ propagandised studies on management and on the effects of...
Tall single-storey steel buildings are commonly used in North America for various applications such as industrial buildings, airplane hangars, recreation centers or warehouse buildings. Typical lateral load resisting system in these buildings is concentrically steel braced frames with two or more bracing tiers stacked between the ground and the roof levels. Multi-tiered steel braced frames represent an economical option for such tall single-storey buildings as smaller braces with reduced expected strengths can be used in...

For several decades, theorists interested in Kant’s discussion of welfare have puzzled over Kant’s position on the issue of the redistribution of goods in society. They have done this both in order to clarify his position and as a source of inspiration for current conceptual problems faced by contemporary political philosophers who attempt to reconcile the ideal of equal freedom with the asymmetric interference necessary for redistribution and social provision. In this paper, I start...
This thesis contributes to the debate on the role and efficacy of pension portability regimes in ensuring both a fair treatment of workers and neutrality as regards to labour mobility choices.Drawing on important contributions from the literature, I perform a comprehensive analysis that aims to bridge the gap between the economic and the political analyses of portability. In addition, I also present novel and unprecedented empirical insights on portability’s effects in the labour market. The...
Big data refers to the collection and aggregation of large quantities of data produced by and about people, things or the interactions between them. With the advent of cloud computing, specialised data centres with powerful computational hardware and software resources can be used for processing and analysing a humongous amount of aggregated data coming from a variety of different sources. The analysis of such data is all the more valuable to the extent that it...

Local species richness is a crucial biodiversity measure also in monitoring projects. This study was carried out in a species-rich beech forest on limestone within the communal forest of the city of Göttingen. It compares species richness estimates from nine surveyors (five individuals and two teams of two) on plots of 4, 100, and 400 m2 size. The influence of surveyor and elapsed time on the outcome was investigated. Additionally, species-specific overlooking and misinterpretation rates...
