We provide the first study of instant messaging (IM) based on large samples of users' self reports. Previous studies have relied on ethnographic methods or analysis of server logs. Our self-report approach has its own strengths (large-sample; focus on attitudes, beliefs, and value attributions), as well as weaknesses (self-selection by respondents). We(More)
This paper provides a description of designers' work practices in a software company. We describe a participatory analysis of the diversity of working relations and roles of designers of IBM's Lotus software products. Designers are an example of a <i>minority discipline</i> - that is, a discipline whose members are often isolated in their work teams among(More)
Primatologists have recognized that non-humans undergo the menopause [Biol. Reprod. 68 (2003) 10], which is preceded by years of irregular cycles and decreased fecundity. The similarity of reproductive changes between humans and baboons suggests that the aging female baboon is a particularly promising model to study human menopause and changes that precede(More)
Recent experiments with specific aminopeptidase inhibitors in rats have strengthened earlier proposals that ANG III may be an important regulatory peptide in the brain. Central mechanisms regulating blood pressure, ingestive behaviors, and vasopressin release could be involved. Arguments in favor of a role for ANG III depend, in part, on the efficacy of ANG(More)
Hormones and growth factors regulate cell growth via the mitogen-activated protein (MAP) kinase cascade. Here we examine the actions of the hormone somatostatin on the MAP kinase cascade through one of its two major receptor subtypes, the somatostatin receptor 1 (SSTR1) stably expressed in CHO-K1 cells. Somatostatin antagonizes the proliferative effects of(More)
Selective breeding of baboons has produced families with increased plasma levels of large high density lipoproteins (HDL1) and very low (VLDL) and low (LDL) density lipoproteins when the animals consume a diet enriched in cholesterol and saturated fat. High HDL1 baboons have a slower cholesteryl ester transfer, which may account for the accumulation of(More)
Adenoviruses (AdVs) are DNA viruses that infect many vertebrate hosts, including humans and nonhuman primates. Here we identify a novel AdV species, provisionally named "simian adenovirus C (SAdV-C)," associated with a 1997 outbreak of acute respiratory illness in captive baboons (4 of 9) at a primate research facility in Texas. None of the six AdVs(More)
A housing and tether system was designed to permit sampling of body fluids, chronic monitoring of physiologic parameters (e.g. blood pressure, heart rate), performance of species typical behavioral interactions (aggression, affiliation, reproduction, etc), physical exercise (work on a motorized treadmill), assessment of water and diet consumption, as well(More)
Very low density lipoprotein (VLDL) and low density lipoprotein (LDL) apoprotein (apo)-B turnover rates were measured simultaneously by injecting 131I-labeled VLDL and 125I-labeled LDL into fasting baboons (Papio sp.) selectively bred for high serum cholesterol levels and having either low or high LDL levels. The radioactivities in VLDL, intermediate(More)
Experimental stress and the administration of the stress hormone ACTH have been reported to stimulate sodium appetite in many nonprimate species. Experiments were conducted to determine whether prolonged intracerebroventricular infusions of the neuropeptides corticotropin-releasing factor (CRF) and urocortin (Ucn), or systemic administration of ACTH,(More)
