The violence of heteronormativity in communication studies: notes on injury, healing, and queer world-making

Abstract: Heteronormativity is everywhere. It is always already present in our individual and collective psyches, social institutions, cultural practices, and knowledge systems. In this essay, I provide some sketches for a critical analysis of heteronormativity in the communication discipline. More specifically, I examine the symbolic, discursive, psychological, and material violence of heteronormativity, and begin exploring ways to heal, grow, transform, and contemplate new possibilities in our social world. To accomplish this, this essay is divided into live sections. First, I discuss the study of sexuality in Communication. Next, through the notion of injury, I focus on the violence of heteronormativity. Third, using the concept of healing, I discuss ways of unpacking heteronormativity through a critique of hegemonic heterosexuality. Further, I offer potential ways for queer world-making through the lens of queer theory. I conclude by exploring the need for more sexuality research in the discipline by engaging the productive tensions between constructive and deconstructive impulses.

Standing out: how new firms in emerging markets build reputation

Abstract: While strategy and organizational researchers increasingly recognize that observers' perceptions and beliefs about firms have a substantive effect on firms' access to resources and performance, the...

Magnetic Activity-related Radial Velocity Variations in Cool Stars: First Results from the Lick Extrasolar Planet Survey

Abstract: The discovery of the radial velocity (v -->r) signatures of planets around several solar-like stars highlights the importance of exploring the sources of v -->r variations intrinsic to the stars themselves. We study the stars in the Lick planetary survey for v -->r variations related to stellar activity: the rotation of starspots and convective inhomogeneities and their temporal evolution. We study the relationships between the weighted v -->r dispersion, ?'v (which has first been corrected for the orbital contribution from known planets and the mean internal error), and spectral type, rotation, and activity (as measured by Ca II H and K). We find that the largest ?'v values occur among both the coolest (dMe) and the warmest (active F) stars. Values of ?'v increase with H and K emission and scale proportional to vsin${r sin}$ -->${r sin}$ -->i in G and K stars and proportional to (vsin${r sin}$ -->${r sin}$ -->i) -->1.3 in F stars. For a G star with vsin${r sin}$ -->${r sin}$ -->i ? 8-10 km s -->?1 (age ~0.3 Gyr), for example, 20 m s -->?1 ?'v 45 m s -->?1, roughly consistent with the predicted ?'v levels due to magnetic activity (Saar & Donahue). All the stars with proposed planetary companions show ?'v values typical for their spectral type, activity, and/or rotation. However, before the planetary v -->r perturbations are removed, these stars show significantly enhanced ?'v values. We develop a simple model that can predict the ?'v expected for a given star (within ? 40%) as a function of vsin${r sin}$ -->${r sin}$ -->i, spectral type, photometric variability, and macroturbulent velocity. The implications for extrasolar planet searches are discussed.

DNA hybridization evidence of hominoid phylogeny: results from an expanded data set.

Abstract: The living hominoids are human, the two species of chimpanzees, gorilla, orangutan, and nine species of gibbons. The cercopithecoids (Old World monkeys) are the sister group of the hominoids. A consensus about the phylogeny of the hominoids has been reached for the branching order of the gibbons (earliest) and the orangutan (next earliest), but the branching order among gorilla, chimpanzees, and human remains in contention. In 1984 we presented DNA-DNA hybridization data, based on 183 DNA hybrids, that we interpreted as evidence that the branching order, from oldest to most recent, was gibbons, orangutan, gorilla, chimpanzees, and human. In the present paper we report on an expanded data set totaling 514 DNA hybrids, which supports the branching order given above. The ranges for the datings of divergence nodes are Old World monkeys, 25–34 million years (Myr) ago; gibbons, 16.4–23 Myr ago; orangutan, 12.2–17 Myr ago; gorilla, 7.7–11 Myr ago; chimpanzees-human, 5.5–7.7 Myr ago. The possible effects of differences in age at first breeding are discussed, and some speculations about average genomic rates of evolution are presented.
