Anatomy of a Governance Transformation: The Case of Daimler-Benz
Logue and Seward examine the evolutionary transformation in the corporate governance structure of Daimler-Benz AG, the largest German industrial company. Over the last several years, Daimler-Benz has taken numerous steps toward prioritizing shareholder value more intensely than ever before
ROSAT HRI Detection of the 16 ms Pulsar PSR J0537-6910 Inside SNR N157B
Based on a deep ROSAT HRI observation, we have detected a pulsed signal in
the 0.1-2 keV band from PSR J0537-6910 --- the recently discovered pulsar
associated with the supernova remnant N157B in the Large Magellanic Cloud. The
measured pulse period 0.01611548182 ms (+- 0.02 ns), Epoch MJD 50540.5, gives a
revised linear spin-down rate of , slightly
greater than the previously derived value. The narrow pulse shape (FWHM = 10%
duty cycle) in the ROSAT band resembles those seen in both XTE and ASCA data (>
2 keV), but there is also marginal evidence for an interpulse. This ROSAT
detection enables us to locate the pulsar at R.A., Dec (J2000) =
. With its uncertainty , this
position coincides with the centroid of a compact X-ray source. But the pulsed
emission accounts for only about 10% of the source luminosity in the 0.1-2 keV band. These results support our previous
suggestions: (1) The pulsar is moving at a high velocity ();
(2) A bow shock, formed around the pulsar, is responsible for most of the X-ray
emission from the source; (3) A collimated outflow from the bow shock region
powers a pulsar wind nebula that accounts for an elongated non-thermal radio
and X-ray feature to the northwest of the pulsar.Comment: 6 pages including 3 figures. To be published in ApJ
An Intersectional Approach to Environmental Political Theory: A Case Study on Modern Andean Bolivian Indigenous Forms of Resistance and Communal Democracy in Relation to Water Rights
Considers Bolivian Andean indigenous forms of democracy and resistance to neoliberal water privatization in Cochabamba. Incorporates environmental identity into the intersectional theoretical framework with principles rooted in Indigenous grass roots theory, Marxist critiques on capitalism, Latin American Neomarxist scholars, and Environmental Justice. Focuses on intersections of ethnicity, gender and class identities with environmental identity to understand the extent to which environmental injustices cannot be addressed in isolation from other sources of inequality

Opposing shear senses in a subdetachment mylonite zone: Implications for core complex mechanics
[1] Global studies of metamorphic core complexes and lowâangle detachment faults have highlighted a fundamental problem: Since detachments excise crustal section, the relationship between the mylonitic rocks in their footwalls and the brittle deformation in their hanging walls is commonly unclear. Mylonites could either reflect ductile deformation related to exhumation along the detachment fault, or they could be a more general feature of the extending middle crust that has been âcaptured â by the detachment. In the first case we would expect the kinematics of the mylonite zone to mirror the sense of movement on the detachment; in the second case both the direction and sense of shear in the mylonites could be different. The northern Snake Range dĂŠcollement (NSRD) is a classic Basin and Range detachment fault with a wellâdocumented topâeast of displacement. We present structural, paleo-magnetic, geochronological, and geothermometric evidence to suggest that the mylonite zone below the NSRD locally experienced phases of both east â and westâdirected shear, inconsistent with movement along a single detachment fault. We therefore propose that the footwall mylonites represent a predetachment dis-continuity in the middle crust that separated localized deformation above from distributed crustal flow below (localizedâdistributed transition (LDT)). The mylonites were subsequently captured by a moderately dipping brittle detachment that soled down to the middle crust and exhumed them around a rolling hinge into a subhorizontal orientation at the surface, produc-ing the presentâday NSRD. In this interpretation the brittle hanging wall represents a series of rotated upper crustal normal faults, whereas the mylonitic footwall represents one or more exhumed middl
