Grounded theory as foundations for methods in applied ontology

Research into domain specific ontologies is difficult to treat empirically. This is because it is difficult to ground domain ontology while simultaneously being true to its guiding philosophy or theory. Further, ontology generation is often introspective and reflective or relies on experts for ontology generation. Even those relying on expert generation lack rigour and tend to be more ad-hoc. We ask how Grounded Theory can be used to generate domain specific ontologies where appropriate high level theory and suitable textual data sources are available. We are undertaking generation of a domain ontology for the discipline of information systems by applying the Grounded Theory method. Specifically we are using Roman Ingarden&rsquo;s theory of scientific works to seed a coding family and adapting the method to ask relevant questions when analysing rich textual data. We have found that a guiding ontological theory, such as Ingarden&rsquo;s, can be used to seed a coding family giving rise to a viable method for generating ontologies for research. This is significant because Grounded Theory may be one of the key methods for generating ontologies where substantial uniform quality text is available to the ontologist. We also present our partial analysis of information systems research.<br /

A Framework for Promoting Diverse Perennial Circular Forage Systems for More Resilient Agricultural Landscapes: Developing Extension and Educational Tools for Resilience and Sustainability

The Resilience CAP Team seeks to use diverse, perennial, circular forage systems (DPCFS) to enhance biodiversity, improve soil and plant health, support ecosystem service, all towards achieving greater resilience to global change and improving the farm economy and quality of life. Our project will design a transdisciplinary framework that combines agronomic, ecological, economic, and sociological factors to achieve greater resilience and stability in agricultural systems through use of DPCFS. In this paper, we describe two of the project’s six objectives. Objective 5 is our extension/outreach arm where we will develop extension media, activities, and actionable decision tools to communicate concepts about the benefits of DPCFS to all stakeholders including farmers, consumers, lenders, and policy makers. To this end, our Extension Team is developing an interactive network of farmers, researchers, and other stakeholders that use multidirectional communication to help reduce barriers to forage use in production systems. Our network will be supported by traditional print and face-to-face approaches, a website, online programming, interactive online decision tools, and social media. Objective 6 is our education arm, where we will develop educational materials on the importance of resilience, ecosystem services, and economic value of DPCFS and integrate the materials into K-12 and university curricula. The activities are designed to develop knowledge and skills associated with sustainable agriculture, with emphasis on DPCFS. Currently, we seek to have multi-institutional internship and graduate seminar programs throughout the year

RQF publication quality measures: methodoligical issues

The Research Quality Framework uses Thomson-ISI citation benchmarks as its main set of objective measures of research quality. The Thomson-ISI measures rely on identifying a core set of journals in which the major publications for a discipline are to be found. The core for a discipline is determined by applying a nontransparent process that is partly based on Bradford&rsquo;s Law (1934). Yet Bradford was not seeking measures about quality of publications or journals. How valid then is it to base measures of publication quality on Bradford&rsquo;s Law? We explore this by returning to Bradford&rsquo;s Law and subsequent related research asking &lsquo;what is Bradford&rsquo;s Law really about?&rsquo; We go further, and ask &lsquo;does Bradford&rsquo;s Law apply in Information Systems?&rsquo; We use data from John Lamp&rsquo;s internationally respected Index of Information Systems Journals to explore the latter question. We have found that Information Systems may have a core of journals only a subset of which is also in the list of Thomson-ISI journals. There remain many unanswered questions about the RQF metrics based on Thomson-ISI and their applicability to information systems.<br /

Evidence for divergent selection between the molecular forms of Anopheles gambiae: role of predation

The molecular forms of Anopheles gambiae are undergoing speciation. They are characterized by a strong assortative mating and they display partial habitat segregation. The M form is mostly found in flooded/irrigated areas whereas the S form dominates in the surrounding areas, but the ecological factors that shape this habitat segregation are not known. Resource competition has been demonstrated between species undergoing divergent selection, but resource competition is not the only factor that can lead to divergence. In a field experiment using transplantation of first instar larvae, we evaluated the role of larval predators in mediating habitat segregation between the forms. We found a significant difference in the ability of the molecular forms to exploit the different larval sites conditioned on the presence of predators. In absence of predation, the molecular forms outcompeted each other in their respective natural habitats however, the developmental success of the M form was significantly higher than that of the S form in both habitats under predator pressure. Our results provide the first empirical evidence for specific adaptive differences between the molecular forms and stress the role of larval predation as one of the mechanisms contributing to their divergence.https://doi.org/10.1186/1471-2148-8-
