Abstract

Rabies is a fatal viral zoonosis that is transmitted by bite contact with saliva of an infected animal. In the U.S., human deaths are rare, but each year over 5,000 rabid animals are reported and over 90% of cases are from wildlife. Multiple species of carnivores and bats are the primary sylvatic reservoirs in the U.S., and several variants circulate independently among these two taxonomic orders. Rabies prevention efforts led by USDA APHIS Wildlife Services using live recombinant vaccine baiting began in 1995 and currently target raccoons and canids, but the territory of the south-central skunk rabies virus variant has been expanding in recent years, leading to incursions into areas previously free of carnivore rabies. Colorado has been one such area, where multiple species of bats were the main rabies reservoir prior to 2007. By 2012, the number of rabid striped skunks exceeded rabid bats in Colorado. Larimer County and Weld County, in Northern Colorado, both witnessed skunk rabies epizootics starting in 2012 that have continued through 2013. Despite spillover events into raccoons, red foxes, companion animals, and livestock during 2012 and 2013, no other host species appears to support independent circulation of the south-central skunk variant in Northern Colorado. Virus isolation from salivary glands of rabid animals will help to quantify the likelihood for secondary transmission from spillover hosts and guide intervention strategies targeting wildlife. We describe the spatiotemporal pattern of the epizootic and predict likely areas of spread along the Front Range of Northern Colorado.

28. Translating OWL and Semantic Web Rules into Prolog: Moving Toward Description Logic Programs

Abstract

To appear in Theory and Practice of Logic Programming (TPLP), 2008. We are researching the interaction between the rule and the ontology layers of the Semantic Web, by comparing two options: 1) using OWL and its rule extension SWRL to develop an integrated ontology/rule language, and 2) layering rules on top of an ontology with RuleML and OWL. Toward this end, we are developing the SWORIER system, which enables efficient automated reasoning on ontologies and rules, by translating all of them into Prolog and adding a set of general rules that properly capture the semantics of OWL. We have also enabled the user to make dynamic changes on the fly, at run time. This work addresses several of the concerns expressed in previous work, such as negation, complementary classes, disjunctive heads, and cardinality, and it discusses alternative approaches for dealing with inconsistencies in the knowledge base. In addition, for efficiency, we implemented techniques called extensionalization, avoiding reanalysis, and code minimization., Comment: 21 pages, 5 figures, 19 tables.

30. Ethical Frameworks, Moral Practices and Outdoor Education.

Author

Fox, Karen M. and Lautt, Mick

Abstract

Insights from quantum physics and chaos theory help create new metaphors about ethical frameworks and moral practices in outdoor education. The seemingly straightforward concept of values is analogous to the initial simple nonlinear equation of a fractal. The value claims of outdoor education--trust, cooperation, environmental awareness, self-awareness, freedom, justice, community, respect--are often interwoven within the very structure and outcomes of programs. If there are repeated iterations of the initial equation (values and value claims), the fractal shapes of ethical frameworks emerge. Ethical frameworks are complex sets of value claims, rationales, and rules that guide moral reasoning, decision making, and behavior. Such complexity implies that various forms, ranging from experiential activities and artistic creations to scholarly essays and research, are necessary to explore ethical frameworks and moral practices of outdoor education. Prominent themes related to outdoor ethical frameworks are: (1) outdoor education research focused on individuals and discrete links among attitudes, knowledge, affect, and behavior; (2) prominent scholarship about outdoor ethical frameworks is becoming more prominent; (3) research findings on moral development in psychology and education indicate the development of moral reasoning is complex; (4) moral practices encompass relational characteristics: love, friendship, compassion, caring, passion, and intuition; (5) spiritual journeys, traditions, and insights are an important aspect of relating to others; and (6) an individual or group can be ethical only when there is mutual material interaction and critique. Understanding the relationships and processes applicable to outdoor values and ethical frameworks requires embracing their complexity. Continuing with physics metaphors from field theory, six ways of embracing complexity are proposed. Contains 124 references. (SV)

Abstract

The first detailed history of imperial and national honours in Australia, Honouring a Nation tells the story of the honours system's transformation from instrument of imperial unity to national institution. From the extension of British honours to colonial Australasia in the nineteenth century, through to Tony Abbott’s revival of knighthoods in the twenty-first, this book explains how the system has worked, traces the arguments of its supporters and critics, and looks both at those who received awards and those who declined them. Honouring a Nation brings to life a long history of debate over honours, including wrangles over State rights, gender imbalances in honours lists, and the emergence and hardening of the Labor/Liberal divide over British awards, illuminating issues that are still part of Australian life—and of the honours system—today. The history of the honours system is equally the history of the nation, revealing who Australians were, what they have become, what they value, and the things that have unified and divided them.
