Cougars (Puma concolor) are elusive top-level predators and their predation patterns, particularly upon sensitive species, can be a source of concern to wildlife managers. Predation patterns, however, vary widely in accordance with differing landscape attributes, prey community composition, and preferences of individual cougars. The objective of this study was to better understand the impact of cougars upon their prey in the Pryor Mountains of Wyoming and Montana. Managers were concerned that cougar predation was having a negative impact upon a small, isolated Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population and were hoping predation might be limiting a burgeoning feral horse population (Equus caballus). With GPS collar data, we examined cougar kills (n = 200) to determine kill rates, prey composition, and selection for prey. Our findings indicated this population of cougars preyed primarily on mule deer (Odocoileus hemionus; 71.5%) but also included a substantial amount of bighorn sheep (8.0%) and other prey items (19.5%) in their diet. All bighorn kills were attributable to a specialist individual and we found no evidence of predation upon feral horses. Results showed that, while cougar predation was not limiting the feral horse population, at times, predation could be one of a host of factors limiting the bighorn sheep population. To better understand the link between the risk of cougar predation and landscape attributes, we examined predation-specific resource selection by cougars. We first compared our set of confirmed kill sites to random sites at a fine scale (within 25 m of kill sites). We then built resource selection functions to conduct a coarse-scale analysis by using the 95% upper cut-off point of the known distances-dragged (94.9 m) to buffer caches sites, thereby creating zones of risk which had high probabilities of containing kill sites. We found that risk of cougar predation was associated with vegetation class and increased with decreasing horizontal visibility. For bighorn sheep, risk of predation was associated with juniper-mountain mahogany (Juniperus spp., Cercocarpus ledifolius) woodlands. We recommend managers thin junipers to increase horizontal visibility in areas where the juniper-mountain mahogany vegetation class intersects bighorn sheep habitat.

It is argued that Pryor's criticism of scepticism of perceptual justification misses the point: while Pryor's dogmatism can provide a successful explication of the perceptual justification of first order empirical beliefs (i.e., an explication of propositional justification), it is barren vis à vis second order sceptical criticisms about the epistemic status of beliefs justified via perception (that is, criticisms pointing to the lack of doxastic justification). We argue that the two main motivations that Pryor offers for his dogmatism –to avoid scepticism of perceptual justification and to explicate perceptual justification– fail due to his commitment with some externalist theses, which make it impossible to satisfy the metaepistemic requisites imposed by the sceptic. Hence given the lack of satisfaction of Pryor's own goals, we conclude that Pryor's dogmatism is not an adequate explication of perceptual justification. / Se argumenta que la crítica de Pryor al escepticismo sobre la justificación perceptiva está fuera de foco: mientras que el dogmatismo puede ser una explicación exitosa sobre la justificación perceptiva de las creencias empíricas de primer orden (i.e. de la justificación proposicional), es estéril frente a las críticas escépticas (de segundo orden) sobre el estatus epistémico de las creencias justificadas perceptivamente (es decir, frente a críticas que señalan la ausencia de justificación doxástica). Argumentamos que las dos principales motivaciones que Pryor ofrece a favor de su dogmatismo –evitar el escepticismo respecto de la justificación perceptiva y proporcionar una explicación intuitiva de la misma– fallan, debido, principalmente, a su compromiso con ciertas tesis de corte externista que imposibilitan la satisfacción de los requisitos metaepistémicos impuestos por el escéptico. En vista de este déficit explicativo respecto a sus propias motivaciones, concluimos que el dogmatismo no es una explicación adecuada de la justificación perceptiva en general.

In this study, an appraisal of the nutritional status of eighty-eight school children has been made, using the Wetzel Index with the Baldwin-Wood Index and the Pryor Index for the determinations.

Beginning with the first European colonists in the New World, captivity has been means of cultural exchange between whites and Native Americans. The narratives recounting the captives’ experiences became popular literature which inspired visual artists who reinterpreted the tales to coincide with their cultural needs. In the early twentieth century, progressive reformer, William Pryor Letchworth, hired artist Henry Kirke Bush-Brown to create a sculpture of captive Mary Jemison who, instead of returning to her natal culture, chose to stay among the Seneca becoming fully assimilated. Aligning with their progressive values, their perception of her character is reflected in the Mary Jemison Monument. The monument creates an image of the ideal woman, immigrant, and Native American who holds and practices white middle-class values of strength, independence, and determination. Exemplifying these American values, the sculpture accesses an American identity emphasizing the acceptance and practice of these supposedly American traits. Immigrants and Native Americans could become fully Americanized by adopting these characteristics and leaving their traditional ways behind. Contingent on their assimilation of white middle-class values, the perceived problems facing a diversified society could be eliminated. In so doing, a more harmonious America aligning with Letchworth’s beliefs could be created.
