Single-molecule dynamic triangulation

A proposal for using single molecules as nanoprobes capable of detecting the trajectory of an elementary charge is discussed in detail. Presented numerical simulations prove that this singlemolecule technique allows determination of a three-dimensional single-electron displacement within a few seconds with an accurocy better than 0.006 nm. Surprisingly, this significantly exceeds the accuracy with which the probe;, molecule itself can be localized (given the same measuring time by means of single-molecule microscopy. It is also shown that the optimal concentration of probe molecules in the vicinity of:the electron (i.e. the concentration which provides the best accuracy of the inferred electron displacement) is of the order of 10(-5) m.

A qualitative cross-level investigation of safety climate perceptions

ver the last few decades occupational health and safety research has shifted its focus away from engineering and ergonomics as a means of improving workplace safety, and has given greater attention to examining the role played by organisational factors, such as safety climate. One factor constraining the advancement of our understanding of the safety climate construct is the tendency of researchers to remain steadfastly bound to the notion that safety climate is measured via a quantative measurement tool. Researchers in the area (e.g., Frone & Barling, 2004; Zohar, 2003) are now arguing for better triangulation of methodologies, in particular better qualitative research, to advance our knowledge and understanding. The present study extends the present body of safety climate literature in two ways; firstly, it addresses this methodological issue via the utilisation of a semi-structured interview methodology and secondly it examines the qualitative structure of safety climate perceptions across different levels (organisation, supervisor and co-worker) and different groups (managers vs. employees). Examination of the interview transcripts revealed qualitative differences and similarities between the different safety climate levels (organisational, supervisor and co-worker) and between manager and employee safety climate perceptions. Implications of these findings for safety climate theory and measurement are discussed.

Youth, Religion and Participation : Theoretical and Methodological Approaches

This roundtable session focus on religious and social change as well as democracy and political culture, startingfrom the role of youth in these processes. The role of religion in young people’s participation is a key theme inthe cross-disciplinary network “youth and religion” connected to the Impact program. Participation here includesboth citizens’ “vertical” capacities to make their voices heard and influence decision-makers in the political system(e.g. via elections or civic organizations and social movements) and their “horizontal” capacities to communicateand cooperate with other people (within society at large or certain associations/communities). The participants ofthe session will present influential theories and methodologies used to study participation among youth within theresearch disciplines they represent (i.e. sociology of religion; theology; ethnology; political science). This will befollowed by a joint discussion of how these theories and methodologies have approached religious involvement witha particular focus on youth’s participation in politics, civil society as well as social media and the internet. The aim ofthe session is to look for common themes and new issues that can guide contemporary studies of participation in thefield of youth and religion. The session is open to conference participants interested in the issues discussed.
