1Shared norms and the evolution of ethnic markersShared norms and the evolution of ethnic markersMcElreath, RichardUnlike other primates, human populations are often divided into ethnic groups that have self-ascribed membership and are marked by seemingly arbitrary traits such as distinctive styles of dress or speech (Barth 1969, 1981). The modern understanding that ethnic identities are flexible and ethnic bou...Ethnic groups; Ethnic identity; Migration; Markers2003-02
2Group selection by selective emigration: the effects of migration and kin structureGroup selection by selective emigration: the effects of migration and kin structureRogers, Alan R.Group selection may operate through selective emigration, as Sewall Wright envisioned, as well as through selective extinction. The discrete-generation model of selective emigration developed here yields the following conclusions. 1. The fitness benefit of altruism, "depends on the frequency of altr...Natural selection; selective extinction; evolution1990-03

4Hadza scavenging: implications for Plio/Pleistocene Hominid subsistenceHadza scavenging: implications for Plio/Pleistocene Hominid subsistenceHawkes, KristenThe frequent association of stone tools and large animal bones in African Plio/Pleistocene archaeological sites has long been taken as evidence of the importance of hunting in early hominid diets. Many now argue that it reflects hominid scavenging, not hunting.Hadza; scavenging; plio/pleistocene; hominid diet1988-04
5Hadza women's time allocation, offspring provisioning, and the evolution of long postmenopausal life spansHadza women's time allocation, offspring provisioning, and the evolution of long postmenopausal life spansHawkes, KristenExtended provisioning of offspring and long postmenopausal life spans are characteristic of all modern humans but no other primates. These traits may have evolved in tandem.

6Herbert Simon's computational models of scientific discoveryHerbert Simon's computational models of scientific discoveryDownes, Stephen M.Herbert Simon's work on scientific discovery deserves serious attention by philosophers of science for several reasons. First, Simon was an early advocate of rational scientific discovery, contra Popper and logical empiricist philosophers of science (Simon 1966). This proposal spurred on investigati...Android epistemology; Psychological processes; Cognitive individualism1990
7High statistics search for ultrahigh energy gamma-ray emission from Cygnus X-3 and Hercules X-1High statistics search for ultrahigh energy gamma-ray emission from Cygnus X-3 and Hercules X-1Kieda, David B.We have carried out a high statistics (2 X 10 9 events) search for ultrahigh energy g-ray emission from the x-ray binary sources Cygnus X-3 and Hercules X-1. Using data taken with the CASA-MIA detector over a five year period (1990-1995), we find no evidence for steady emission from either source. T...Cygnus X-3; Hercules X-1; Ultrahigh energy; X-rays1997

9Units of decisionUnits of decisionThalos, Mariam G.I shall introduce the units of decision problem in the theory of decision, which as I shall explain is a sibling to the units of selection problem in evolutionary theory. And I shall present an argument to the effect that, contrary to Bayesian wisdom on the subject, undertaking decision in group set...Decision theory; Collective will; Cooperation; Individualism1999-09
10Use of strain typing data to estimate bacterial transmission rates in healthcare settingsUse of strain typing data to estimate bacterial transmission rates in healthcare settingsAdler, Frederick R.; Jackson, Brian Richard; Carroll, Karen C.; Samore, Matthew H.OBJECTIVE: To create an affordable and accurate method for continuously monitoring bacterial transmission rates in healthcare settings. DESIGN: We present a discrete simulation model that relies on the relationship between in-hospital transmission rates and strain diversity. We also present a proof...Strain typing; Infection control; Transmission model2005
11Trouble with superselection accounts of measurementTrouble with superselection accounts of measurementThalos, Mariam G.Argues that the superselection accounts of measurement exploit excess structure illegitimately and in the process become self-contradictory. Superselection rule in the quantum-mechanical treatment of phenomena; Representation of indicator states of detectors by eigenspaces of superselection operatio...Superselection; Quantum mechanics1998-11
12Stumped by trees? A generalized null model for patterns of organismal diversityStumped by trees? A generalized null model for patterns of organismal diversityAdler, Frederick R.Evolutionary biologists increasingly have become interested in the factors determining the structure of phylogenetic trees. For example, highly asymmetric trees seem to suggest that the probability of extinction and/or speciation differs among lineages.Evolutionary diversification; phylogenetic topologies; speciation1995
13Adaptive complexity and phenomenal consciousnessAdaptive complexity and phenomenal consciousnessNichols, ShaunFocuses on epiphenomenalism problems in arguments about evolutionary function of phenomenal consciousness. Implications of cognitive neuropsychology evidence for the structure of phenomenal consciousness; Distinction of different kinds of epiphenominalist arguments; Provision of a developmental basi...Cognitive neuroscience; Cognizant; Exceptional2001-09-11
14Age-rationing and the just distribution of health care: Is there a duty to die?Age-rationing and the just distribution of health care: Is there a duty to die?Battin, Margaret P.The author analyzes the argument that a policy involving distributive justice in the allocation of scarce health care resources, based on the strategy of rational self interest maximation under a veil of ignorance (Rawls/Daniels), would result in an age rationing system of voluntary, socially encour...Health care providers; Death; Euthanasia1987-01

17Food sharing among Ache hunter-gatherers of Eastern ParaguayFood sharing among Ache hunter-gatherers of Eastern ParaguayHawkes, KristenEmpirical research on food sharing among hunter-gatherers should provide critical data for evaluating both the possible role of food sharing in hominid evolution and the question of how such behavior could be selected.Hunter-gatherers; ache; paraguay; anthropology1988-02
18Evolution of individuality by Leo W. BussEvolution of individuality by Leo W. BussSeger, JonMetazoans seldom reproduce vegetatively; they often die of cancer; and they almost always sequester their germ lines. Plants often reproduce vegetatively, seldom die of cancer, and almost never sequester a germ line. Buss argues that these and many other patterns can all be understood in a unified w...Cell lines; Hierarchy; Biology1988
19Evolution of mating preferences and major histocompatibility complex genesEvolution of mating preferences and major histocompatibility complex genesPotts, Wayne K.House mice prefer mates genetically dissimilar at the major histocompatibility complex (MHC). The highly polymorphic MHC genes control immunological self/nonself recognition; therefore, this mating preference may function to provide "good genes" for an individual's offspring. However, the evidence ...Inbreeding; Parasites; Recognition1999
20Evolution of water transport and xylem structureEvolution of water transport and xylem structureSperry, John S.Land plants need water to replace the evaporation that occurs while atmospheric CO2 is diffusing into photosynthetic tissue. The water-for-carbon exchange rate is poor, and evolutionary history indicates a progression of innovations for cheap water transport--beginning in order with capillary sucti...Cavitation; Vessels; Plants2003
21Experimental study of diffuse competition in harvester antsExperimental study of diffuse competition in harvester antsDavidson, Diane W.Experiments carried out over a 5-yr period in the Chihuahuan Desert support the a priori prediction of diffuse competition between two species of harvester ants. Despite dietary overlap between a large species {Pogonomyrmex rugosus) and a small species (Pheidole xerophila), the large species facilit...Chihuahuan Desert; Ants; Facilitation; Resource allocation; Granivory1985
22Explanation in classical population geneticsExplanation in classical population geneticsPlutynski, AnyaThe recent literature in Philosophy; of biology has drawn attention to the different sorts of explanations proffered in the biological sciences--we have molecular, biomedical, and evolutionary explanations.

23Can females gain additional paternal investment by mating with multiple males? a game theoretic approachCan females gain additional paternal investment by mating with multiple males? a game theoretic approachMcElreath, RichardAlthough females may require only one mating to become inseminated, many female animals engage in costly mating with multiple males. One potential benefit of polyandrous mating is gaining parental investment from multiple males. We developed two game theoretic models to explore this possibility. Our...Female multiple mating; Polyandry; Nonprocreative mating; Paternal investment; Mating benefits; Mating strategy2001-11
