Selenomethionine labeling of large biological macromolecular complexes: probing the structure of marine bacterial virus PM2.
2008
There is a need for improved tools for labeling protein species within large macromolecular assemblies. Here we describe a method for the efficient selenomethionine labeling of the membrane-containing bacterial virus PM2 for structural studies. By examining potential host cells a strain was found which was auxotrophic for methionine, and by performing a multiparameter search of conditions it was possible to derive a robust protocol which simultaneously minimized the toxic effects of the selenomethionine, so that a reasonable virus yield was maintained, whilst still achieving essentially complete labeling. This has allowed us to fingerprint the protein constituents of the virus in a relative…
Impact of COVID-19 on the self-reported physical activity of people with complete thoracic spinal cord injury full-time manual wheelchair users

Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Activitat física; Lesió medul·lar Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Actividad física; Lesión de la médula espinal Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Physical activity; Spinal cord injury Context The emergence of COVID-19 caused a new public health crisis, leading to major changes in daily life routines, often including physical activity (PA) levels. The main goal of this study was to analyze the differences in self-reported physical activity of people with complete spinal cord injuries between the time prior to the COVID-19 lockdown and the lockdown period itself. Methods A sample of 20 participants with complete thoracic spi…
Do fee-shifting rules affect plaintiffs’ win rates? A theoretical and empirical analysis
2021
Abstract This article studies whether fee-shifting rules can affect plaintiffs’ win rates. Beyond theoretical modeling, this study goes a step further and provides empirical evidence on this issue, thanks to the study of a real change in Spanish legislation. Spain applied the so-called English rule in 2011 in the administrative jurisdiction. This study explores whether plaintiffs were more or less successful when litigating against public administrations since then. After controlling for several other factors, it is shown that the new rule considerably increased plaintiffs’ win rate (while also reducing litigation). The paper also presents a theoretical model explaining that the English rul…
Return Migration Process in Policy and Practice
2019
AbstractThis chapter focuses on return migration processes in Latvia, integrating analysis of return migration policy and the experiences of return migrants. The analysis considers the extent to which return policy activities correspond to the needs and expectations of the target group, and addresses the role of this policy in the process of making the decision to return. The data used for the analysis are policy planning documents, The Emigrant Communities of Latvia survey and in-depth interviews. The main empirical evidence of the return experiences of migrants in the chapter comes from 18 in-depth interviews with Latvian returnees from various age and social status groups, who left Latvi…
A meta-study of athletic identity research in sport psychology: Current status and future directions
2015
ABSTRACTThe aim of this meta-study is to provide a critical synthesis of qualitative research on athletic identity in sport psychology. A total of 108 empirical studies were identified, including 63 quantitative studies, 40 qualitative studies, and five mixed methods studies. Qualitative and mixed methods studies were reviewed with the meta-study method, which involves a meta-analysis in terms of theoretical perspectives, methodologies, and findings. In our discussion we focus on evaluating and critiquing the current status of qualitative research on athletic identity and outlining recommendations for improving methodological rigor. It is concluded that both quantitative and qualitative stu…
Agency at Work, Learning and Professional Development: An Introduction
2017
The concept of agency refers to individuals’ capacity to make choices and to act on these choices to exert control over their lives. Such notions of agency have become increasingly popular within discourses on professional learning and development over the last 10–20 years. Unfortunately, these discourses have been rather abstract in nature. In addition, the various research strands concerned with agency in the workplace and its relationship to learning have been insufficiently integrated. The present book thus aims to collect, integrate and discuss within a single volume the range of perspectives on agency at work and the empirical research generated by these perspectives. It is hoped that…
What makes environmental performance differ between firms? Empirical evidence from the Spanish tile industry
2007
Environmental performance is a matter of major concern both for policy makers and for firm managers. In this paper we interpret firms' environmental performance as their ability to reduce polluting wastes while maintaining observed levels of inputs and desirable outputs. Making use of data envelopment analysis techniques, we compute waste-specific environmental efficiency measures for a sample of ceramic-tile producers located in the eastern Spanish region of Valencia. Our results show that there exists substantial room for improving environmental performance, which would have highly beneficial consequences for the local environment. In a second stage of analysis, we find that affiliation …
Introduction: Europe, Heritage and Memory—Dissonant Encounters and Explorations
2019
AbstractThe introduction to Dissonant Heritages and Memories in Contemporary Europe theoretically grounds the book’s various problematizations of heritage and identity struggles in Europe today, including the heritage policies of the EU and other intergovernmental organizations, struggles over ethnographic and historical exhibitions, activist practices, and dissonant memories. By discussing these struggles and their problematizations, the introduction connects the book to a wide range of ongoing debates across the humanities and social sciences. At the same time, it discusses how convergences and divergences within and between the volume’s chapters foster new insights regarding the concepts…
Spatial Perspective on Everyday Transitions Within a Toddler Group Care Setting
2017
This chapter builds on spatial approaches to study everyday life, and in particular to consider Henri Lefebvre’s (1901–1991) theory on the social production of space. Lefebvre’s ideas on the social production of space are based on a dynamic “spatial triad” of conceived (representations of space), perceived (socio-spatial practices), and lived space (representational space). The aim of this chapter is to discuss, by building on Lefebvre’s approach, the spatial dynamics involved within the small-scale (horizontal) transitions for children in toddler group care. The discussion is based on a study where one Finnish day care group for 1- to 3-year-olds was investigated by applying a spatial, rel…
