Group formation, styles, and grammars of commonality in local activism.

Authors:
Eeva Luhtakallio

Br J Sociol 2018 Nov 8. Epub 2018 Nov 8.

University of Tampere.

This article argues that in order to analyse democracy as a pattern constantly processed in a given society, it is useful to look at activist groups' agenda setting and recruitment principles, group bonds and boundaries, and how these actions direct and influence ways of creating the common. Based on an ethnographic study on bicycle activism in Helsinki, Finland, it describes a local critical mass movement that was successful in promoting a bicycle friendly and sustainable city, yet dissolved due to lack of people involved, and the bicycle demonstrations stopped at a moment of high public interest. This empirical puzzle is addressed by combining three theoretical perspectives: Kathleen Blee's work on path dependencies in nascent activist groups; Nina Eliasoph and Paul Lichterman's work on group styles, and Laurent Thévenot's work on the grammars of commonality.

How a linear triazene photoisomerizes in a volume-conserving fashion.

Phys Chem Chem Phys 2018 Nov;20(44):28075-28087

Theoretische Chemie, Ruhr-Universität Bochum, 44780 Bochum, Germany.

Understanding deactivation mechanisms of functional groups is a key step to design novel photo-active devices and molecular imaging agents. Here, we elucidate the photochemistry of linear triazenes, an extended analogue of the photo-switchable azo group, exemplarily for the widely used DNA-minor-groove binder berenil. Combining ultrafast spectroscopy and ab initio calculations unveils that the E-azo,s-trans structure of berenil predominates in the gas phase and in aqueous solution, and ADC(2) intrinsic reaction coordinate calculations disclose that the excited-state relaxation to the S1 minima/conical intersections follows a two-step mechanism: N[double bond, length as m-dash]N bond stretching followed by a bicycle-pedal rotation in the triazene bridge.

Chronotropic incompetence to exercise in anorexia nervosa patients during the body-weight recovery phase as an index of insufficient treatment.

Heart Vessels 2018 Oct 19. Epub 2018 Oct 19.

Institute for Integrated Sports Medicine, Keio University School of Medicine, Tokyo, Japan.

Resting bradycardia is an important symptom for early diagnosis of anorexia nervosa (AN) during weight loss, and it improves with body-weight recovery. However, chronotropic incompetence (CI) in exercise is observed in some patients with AN despite amelioration of resting bradycardia in the recovery phase. We examined the relationship between CI in exercise and other parameters in patients with AN during the recovery phase. Read More

(E-)Cyclists running the red light - The influence of bicycle type and infrastructure characteristics on red light violations.

Accid Anal Prev 2019 Jan 16;122:99-107. Epub 2018 Oct 16.

TU Chemnitz, Cognitive and Engineering Psychology, Germany. Electronic address:

Red light running is one of the most common traffic violations among cyclists. From different surveys, we know that about 40% of all cyclists run a red light at least occasionally. However, specific data on red light running of e-bike riders (pedelec and S-pedelec riders), a population of cyclists that has been growing steadily in the past few years in Germany and elsewhere, is largely missing.

Fatal cyclist crashes in Australia.

Traffic Inj Prev 2018 Oct 18:1-5. Epub 2018 Oct 18.

a Monash University Accident Research Centre , Clayton , Victoria , Australia.

Objectives: The number of casualty road crashes in Australia has steadily reduced over the past few decades; however, a concurrent reduction has not been achieved for crashes involving cyclists. This has resulted in a disproportionate overrepresentation of cyclists in fatal injury statistics. This article explores the contributing factors and injury mechanisms among coronial reported fatal cyclist crashes in Australia. Read More

SBP above 180 mmHg at moderate exercise workload increases coronary heart disease risk in healthy men during 28-year follow-up.

J Hypertens 2018 Oct 12. Epub 2018 Oct 12.

Department of Cardiology, Oslo University Hospital, Ullevaal.

Objective: We investigated the association between exercise SBP at a moderate workload and long-term risk of coronary heart disease (CHD) in men who were healthy when assessed by two bicycle exercise tests 7 years apart.

Methods: During 1972-1975, apparently healthy men (n = 1999) were initially enrolled following thorough medical examination and ECG-monitored bicycle exercise test. Participants (n = 1392) who were healthy also at a second exercise test 7 years later were included in the present study. Read More
