Cognition in contests: mechanisms, ecology, and evolution

Animal contests govern access to key resources and are a fundamental determinant of fitness within populations. Little is known about the mechanisms generating individual variation in strategic contest behavior or what this variation means for population level processes. Cognition governs the expression of behaviors during contests, most notably by linking experience gained with decision making, but its role in driving the evolutionary ecological dynamics of contests is only beginning to emerge. We review the kinds of cognitive mechanisms that underlie contest behavior, emphasize the importance of feedback loops and socio-ecological context, and suggest that contest behavior provides an ideal focus for integrative studies of phenotypic variation

Portrayal of Interactions Between Humans and Coyotes (Canis latrans): Content Analysis of Canadian Print Media (1998-2010)

Print media is one form of public discourse that provides a means to examine human-coyote interactions. We conducted a content analysis of 453 articles addressing coyote events reported in the Canadian print media between 1998 and 2010. We found 119 articles about human-coyote interactions, of which 32 involved a report of coyote biting (26) or attempting to bite (6) a person. 108 articles were about coyote-dogs and 32 about coyotes-cat interactions. Remaining articles were on topics unrelated to interactions (e.g. culls). Basing our analysis in grounded theory, we identified important descriptive and emotional themes surrounding these events. The most common words describing coyotes were: brazen, wiley, mangy, nuisance, wild and vicious. Interactions were described as attacks in 185 articles, while only 32 “attacks” were identified. Coyotes were portrayed as not natural in cities, as an invasive species, and more recently using language depicting criminal behaviour. Descriptions of coyotes killing or attacking people were inflammatory (e.g. savaged, ripped juts open), whereas descriptions of people killing coyotes were not (e.g. euthanized). Five emotional responses emerged describing humans involved in coyote interactions. Of these, statements of fear were most prevalent and yielded the richest understanding of perceptions about the risk of coyote-human interactions, including: fear for children’s safety (73), fear for disease (44), fear for pet safety (43), and fear for self or others safety (35). Traumatic response was reported in 28 articles, while sadness and grief were described in 17. Two other themes were: 1) animal welfare concerns, 2) frustration due to lack of agency response. Popular media plays a critical role in shaping public understanding and can influence people’s emotional experiences, perceptions and management consequences. We highlight that coyotes are prejudiced (and stereotyped) based on the isolated and sensationalized incidents. Coyotes in particular elicit a wide range of emotional responses in people, and there is often a wide gap between perception and reality of risk when understanding whether it is possible for humans and coyotes to co-exist. Hence, there is a strong need for media literacy about the unintended or intended maligning of coyotes to the general public, as the consequence can be social amplification of risk and the unwarranted persecution of coyotes

Academic Primer Series: Five Key Papers for Consulting Clinician Educators.

INTRODUCTION: Clinician educators are often asked to perform consultations for colleagues. Invitations to consult and advise others on local problems can help foster great collaborations between centers, and allows for an exchange of ideas between programs. In this article, the authors identify and summarize several key papers to assist emerging clinician educators with the consultation process. METHODS: A consensus-building process was used to generate a list of key papers that describe the importance and significance of educational consulting, informed by social media sources. A three-round voting methodology, akin to a Delphi study, determined the most impactful papers from the larger list. RESULTS: Summaries of the five most highly rated papers on education consultation are presented in this paper. These papers were determined by a mixed group of junior and senior faculty members, who have summarized these papers with respect to their relevance for their peer groups. CONCLUSION: Five key papers on the educational consultation process are presented in this paper. These papers offer background and perspective to help junior faculty gain a grasp of consultation processes

Effects of contaminants of emerging concern on Megaselia scalaris (Lowe, Diptera: Phoridae) and its microbial community.

Drought, rising temperatures, and expanding human populations are increasing water demands. Many countries are extending potable water supplies by irrigating crops with wastewater. Unfortunately, wastewater contains biologically active, long-lived pharmaceuticals, even after treatment. Run-off from farms and wastewater treatment plant overflows contribute high concentrations of pharmaceuticals to the environment. This study assessed the effects of common pharmaceuticals on a cosmopolitan saprophagous insect, Megaselia scalaris (Diptera: Phoridae). Larvae were reared on artificial diets spiked with contaminants of emerging concern (CECs) at environmentally relevant concentrations. Female flies showed no oviposition preference for treated or untreated diets. Larvae exposed to caffeine in diets showed increased mortality, and larvae fed antibiotics and hormones showed signs of slowed development, especially in females. The normal sex ratio observed in M. scalaris from control diets was affected by exposure to caffeine and pharmaceutical mixture treatments. There was an overall effect of treatment on the flies' microbial communities; notably, caffeine fed insects displayed higher microbial variability. Eight bacterial families accounted for approximately 95% of the total microbes in diet and insects. Our results suggest that CECs at environmentally relevant concentrations can affect the biology and microbial communities of an insect of ecological and medical importance

Relationships between School Desegregation and Government Housing Programs: A Milwaukee Case Study

School desegregation was initiated in Milwaukee in the 1976-77 school year through a court-ordered city desegregation program and a state-financed city-suburban pupil transfer program. This pilot study by the Metropolitan Integration Research Center explored three dimensions of the complex interrelationships between these school desegregation programs and housing patterns in Milwaukee County. First, a field study explored the attitudes of minority families participating in the innovative city-suburban school desegregation program. The survey found high satisfaction with the educational program and relatively strong interest in possible integrating housing moves to suburban areas where children were busing to school. Secondly, the pupil movement under the city and metropolitan desegregation plans was assessed for its impact on segregated residential housing patterns in the community. The largely voluntary plan implemented by the Milwaukee Public Schools appeared to have negative impacts on racially changing neighborhoods. The highest percentages of students were leaving schools in residentially integrated areas, and schools in transitional areas were allowed to tip to predominantly black. The third aspect of the study analyzed federal rental housing programs operating in the county. The Section 8 rent assistance program, operated by three governmental units in Milwaukee County, appeared to reinforce the segregated housing patterns of the community and failed to complement school desegregation efforts. Scattered site and traditional public housing provided by the City of Milwaukee also impacted negatively on the racial make-up of neighborhood schools in the city. The study suggests the need for more coordinated efforts by school and housing officials if successful, long-range integration is to occur

A Competing Values Framework for Analyzing Presentational Communication in Management Contexts

Communication specialists have long been interested in analyzing messages. More recently, they have stressed the need for evaluative tools that account for situational ex pectations and constraints. Drawing from the literature on organizational and managerial effectiveness, we constructed an empirical model applicable to presenta tional communication. Over 100 communication professors evaluated the relevance of descriptors for six different types of business presentations: three oral and three writ ten. Their judgments were used to create similarity scores, which were submitted to multidimensional scaling. A three-dimensional model emerged. This "competing values model" illustrates the dynamic interplay between the highly contrasting charac teristics of four general types of presentational communication: relational, information al, instructional, and transformational. In conclusion, we discuss the benefits of the model and suggest its usefulness as an evaluative tool, particularly for the training of managers.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68906/2/10.1177_002194369102800303.pd

Coexisting with Cougars: Public Perceptions, Attitudes, and Awareness of Cougars on the Urban-Rural Fringe of Calgary, Alberta, Canada

Interactions between humans and cougars (Puma concolor) have been steadily increasing over the past 20 years largely due to human encroachment into cougar habitat and an increase in the human population. We determined the attitudes, knowledge, and perceptions toward cougars by residents in the urban-rural fringe of Calgary, Alberta, Canada, an area populated by both cougars and humans. We sent a survey to a stratified, random sample of 1,508 residents. Survey analysis included a potential for conflict index (PCI) to help provide quantitative direction for future cougar management. We analyzed and tested for differences among 7 variables: livestock ownership, gender, age, education, community of residence, years at residence, and experience with cougars. We found an overall positive attitude toward the presence of cougars in the area. However, residents indicated a low level of knowledge concerning regional wildlife management and wished to be more directly involved in planning and decision making. Recommendations developed from this study included: increasing the awareness of cougars through targeted education, facilitating of stakeholder involvement, developing of proactive cougar management strategies, and exploring adaptive management
