We’re Not Like Those Crazy Hippies: The Dynamics of Jurisdictional Drift in Externally Mandated Occupational Groups
External actors often advocate for organizations to address a wide range of societal concerns, such as diversity, equality, and sustainability, and organizations have frequently responded by establishing new positions to oversee these demands. However, calls to address social problems can be broad and unrelated to an organization’s primary objectives, so the external mandates that underpin these new positions do not easily translate to clear task jurisdictions inside organizations. Furthermore, previous studies have found that the tasks that are pursued by occupations established through external pressure often diverge from what external groups had envisioned for these new roles. This study addresses the question of why this divergence occurs. It does so by examining the formation of the occupational group of sustainability managers in higher education. Through fieldwork, interviews, and analyses of longitudinal archival data, this paper uncovers the dynamics of jurisdictional drift and shows how jurisdictional drift unfolded first through sustainability managers’ confrontation of their jurisdictional ambiguity, and then through their efforts at performing neutrality, in particular by trading external Politics for internal politics and trading values for standards. Additionally, it uncovers how the sustainability managers attempted to partially realign their jurisdiction with their external mandate, but did so in a concealed manner. This study illuminates the process of how jurisdictions can come to drift away from mandates, highlights the importance of studying how mandates are translated into jurisdictions, and also furthers our understanding of the formation of externally mandated occupational groups
Pseudospectra of the heat operator Pencil
This article undertakes an analysis of the one-dimensional heat equation,
wherein the Dirichlet condition is applied at the left end and Neumann
condition at the right end. The heat equation is restructured as a
non-self-adjoint unbounded block operator matrix pencil. The
spectral, pseudospectral, and -pseudospectral enclosures of the
unbounded block operator matrix pencil are explored to scrutinize
the heat operator pencil. The plots of the discretized equation are depicted to
illustrate the observations
A Cultural Resources Survey for Medina Electric Cooperative, Inc., in Uvalde, Medina, and Frio Counties, Texas
The Center for Archaeological Research (CAR), The University of Texas at San Antonio (UTSA), under contract with Alexander Utility Engineering, Inc., (letter dated May 5, 1980), conducted an archaeological survey for the Medina Electric Cooperative, Inc. Although the CAR was contracted in May 1980, at the request of Medina Electric Cooperative, Inc., the actual survey was not carried out until February 25-March 1, 1981. The survey, which was conducted in three neighboring south Texas counties (Fig. 1), was concentrated along proposed electrical distribution lines at D1Hanis in Medina County, north of Uvalde in Uvalde County, and southwest of Pearsall in Frio County. General supervision of the project was provided by Dr. Thomas R. Hester, Director, and Jack D. Eaton, Associate Director, of the CAR-UTSA. The project was carried out by Augustine and Elizabeth Frkuska, Center staff archaeologists
An application of Martingale convergence theorem to analyse company data
Martingale Convergence Theorem, in a slightly general form, when applied to the process of investor's fortune tells that an investor with a limited aim of enhancing her fortune k-fold will, in due course, either attain her aim or lose the entire initial investment. We verify and apply this theorem to analyse certain company data
DNA binding proteins of rat thigh muscle: purification and characterization of an endonuclease
Two major DNA binding proteins of molecular weights 34,000 and 38,000 have been identified in the 30,000 g supernatant (S-30) fraction of rat thigh muscle extracts. The presence of 38 KD DNA binding protein in the muscle S-30 could be demonstrated only if Triton X-100 treated extracts were used for Afinity chromatography suggesting that this protein may be a membrane associated DNA binding protein. The 38 KD DNA binding protein differed from the 34 KD DNA binding protein also in its chromatographic behaviour in DE-52 columns in which the 38 KD protein was retained, while the 34 KD protein came out in the flow-through in an electrophoretically pure form. The 34 KD DNA binding protein can also be purified by precipitation with MgCl2. Incubation of 0 · 15 M NaCl eluates (containing the 38 KD and/or 34 KD DNA binding protein) in the presence of 100 mM Mg2+ resulted in the specific precipitation of the 34 KD protein. Prolonged incubation (30 days) of the 0 · 15 Ì NaCl eluates containing the two DNA binding proteins at 4°C led to the preferential degradation of the 34 KD DNA binding protein. Nitrocellulose filter binding assays indicated selective binding of purified 34 KD protein to ss DNA. Purified 34 KD DNA binding protein cleaved pBR 322 supercoiled DNA, and electrophoresis of the cleavage products in agarose gels revealed a major DNA band corresponding to the circular form of DNA
Integrating aerodynamics and structures in the minimum weight design of a supersonic transport wing
An approach is presented for determining the minimum weight design of aircraft wing models which takes into consideration aerodynamics-structure coupling when calculating both zeroth order information needed for analysis and first order information needed for optimization. When performing sensitivity analysis, coupling is accounted for by using a generalized sensitivity formulation. The results presented show that the aeroelastic effects are calculated properly and noticeably reduce constraint approximation errors. However, for the particular example selected, the error introduced by ignoring aeroelastic effects are not sufficient to significantly affect the convergence of the optimization process. Trade studies are reported that consider different structural materials, internal spar layouts, and panel buckling lengths. For the formulation, model and materials used in this study, an advanced aluminum material produced the lightest design while satisfying the problem constraints. Also, shorter panel buckling lengths resulted in lower weights by permitting smaller panel thicknesses and generally, by unloading the wing skins and loading the spar caps. Finally, straight spars required slightly lower wing weights than angled spars
