Migration and demos in the democratic firm: an extension of the firm-state analogy

Debates around the state-firm analogy as a route to justifying workplace democracy tend towards a static view of both state and firm, and position workplace democracy as the objective. We contend, however, that states and firms are connected to one another in ways that should alter the terms of the debate, and that the achievement of workplace democracy raises a new set of political issues about the demos in the democratic firm and ‘worker migration’ at the boundaries of the firm. Our argument thus contains two key steps: First, drawing on an empirical case study of a worker-owned firm, we enrich the state-firm analogy by developing a more dynamic view of both, focussing on the creation of workplace democracies; worker movement in and out of them; the dynamic meanings of ‘citizenship’ within them; and the status of the unemployed in a world of democratic workplaces. We then argue that in moving to a more sociological view of the state, the things we were comparing begin to show their real-world connections to one another. By going beyond the idealised view of states that has distorted the state-firm analogy debates, we arrive at a more robust view of how widespread workplace democracy might reconfigure basic political relationships in society

How to use magnetic field information for coronal loop identification?

The structure of the solar corona is dominated by the magnetic field because the magnetic pressure is about four orders of magnitude higher than the plasma pressure. Due to the high conductivity the emitting coronal plasma (visible e.g. in SOHO/EIT) outlines the magnetic field lines. The gradient of the emitting plasma structures is significantly lower parallel to the magnetic field lines than in the perpendicular direction. Consequently information regarding the coronal magnetic field can be used for the interpretation of coronal plasma structures. We extrapolate the coronal magnetic field from photospheric magnetic field measurements into the corona. The extrapolation method depends on assumptions regarding coronal currents, e.g. potential fields (current free) or force-free fields (current parallel to magnetic field). As a next step we project the reconstructed 3D magnetic field lines on an EIT-image and compare with the emitting plasma structures. Coronal loops are identified as closed magnetic field lines with a high emissivity in EIT and a small gradient of the emissivity along the magnetic field.Comment: 14 pages, 3 figure

2-Chloro-3-(4-chloro­benzamido)-1,4-naphthoquinone

The naphthoquinone ring is almost perpendicular [dihedral angle 71.02 (3)°] to the phenyl group of the title compound, C17H9Cl2NO3, while the dihedral angle between the amide group and the 4-chloro­phenyl ring is 21.9 (2)°. The conformation of the N—H and C=O bonds are anti to each other. N—H⋯Cl hydrogen bonds link the mol­ecules into chains in the a-axis direction. In addition, these chains are linked by weak inter­molecular C—H⋯O inter­actions

Polymorphs and hydrates of acyclovir

Acyclovir (ACV) has been commonly used as an antiviral for decades. Although the crystal structure of the commercial form, a 3:2 ACV/water solvate, has been known since 1980s, investigation into the structure of anhydrous ACV has been limited. Here, we report the characterization of four anhydrous forms of ACV and a new hydrate in addition to the known hydrate. Two of the anhydrous forms appear as small needles and are stable to air exposure, whereas the third form is morphologically similar but quickly absorbs water from the atmosphere and converts back to the commercial form. The high-temperature modification is achieved by heating anhydrous form I above 180°C. The crystal structures of anhydrous form I and a novel hydrate are reported for the first time. © 2010 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 100:949–963, 2011Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/79417/1/22336_ftp.pd

Finding the best proxies for the solar UV irradiance

Solar UV emission has a profound impact on the upper terrestrial atmosphere. Because of instrumental constraints, however, solar proxies often need to be used as substitutes for the solar spectral variability. Finding proxies that properly reproduce specific spectral bands or lines is an ongoing problem. Using daily observations from 2003 to 2008 and a multiscale statistical approach, we test the performances of 9 proxies for the UV solar flux. Their relevance is evaluated at different time-scales and a novel representation allows all quantities to be compared simultaneously. This representation reveals which proxies are most appropriate for different spectral bands and for different time scales.Comment: to appear in Geoph. Res. Let

Junkie love : romance and addiction on the big screen

This article investigates the filmic construction of two disparate but intertwining cultural practices: those engaging in the life-affirming rituals of romantic love and those performing the potentially self-destructive rituals of hard drug consumption. Discussing a number of key feature films from the (mini) genre “junkie love”, it aims to show what happens when elements of mainstream romantic drama merge with the horror conventions of the heroin addiction film. Drawing amongst others on Murray Smith’s theory of “levels of [spectator] engagement” and Greg Smith’s concept of the “emotion system”, the article concludes that junkie love films, using tropes of the romantic tragedy in the tradition of Romeo and Juliet, present a more complex and nuanced approach to drug addicts than the predominantly condemnatory media coverage—one that arguably invites the spectator’s understanding and compassion
