TL;DR: In this article, a framework for considering compositional heterogeneity (the number and proportions of different cover types) and configurational heterogeneity, the spatial arrangement of cover types, is proposed.
Abstract: Biodiversity in agricultural landscapes can be increased with conversion of some production lands into 'more-natural'- unmanaged or extensively managed - lands. However, it remains unknown to what extent biodiversity can be enhanced by altering landscape pattern without reducing agricultural production. We propose a framework for this problem, considering separately compositional heterogeneity (the number and proportions of different cover types) and configurational heterogeneity (the spatial arrangement of cover types). Cover type classification and mapping is based on species requirements, such as feeding and nesting, resulting in measures of 'functional landscape heterogeneity'. We then identify three important questions: does biodiversity increase with (1) increasing heterogeneity of the more-natural areas, (2) increasing compositional heterogeneity of production cover types and (3) increasing configurational heterogeneity of production cover types? We discuss approaches for addressing these questions. Such studies should have high priority because biodiversity protection globally depends increasingly on maintaining biodiversity in human-dominated landscapes.

TL;DR: The more recent concepts of point equilibrium and static stability, which characterize the classical equilibrium paradigm in ecology, are traceable to the assumptions implicit in "balance of nature" as mentioned in this paper, which has failed not only because equilibrium conditions are rare in nature, but also because of our past inability to incorporate heterogeneity and scale multiplicity into our quantitative expressions for stability.
Abstract: A common assumption historically in ecology is evident in the term "balance of nature." The phrase usually implies that undisturbed nature is ordered and harmonius, and that ecological systems return to a previous equilibrium after disturbances. The more recent concepts of point equilibrium and static stability, which characterize the classical equilibrium paradigm in ecology, are traceable to the assumptions implicit in "balance of nature." The classical equilibrium view, however, has failed not only because equilibrium conditions are rare in nature, but also because of our past inability to incorporate heterogeneity and scale multiplicity into our quantitative expresssions for stability. The theories and models built around these equlibrium and stability principles have misrepresented the foundations of resource management, nature conservation, and environemtnal protection. In this paper, we sysntesize recent developments that advance our understandings of equilibrium vs. nonequilibrium, homogeneity vs....

TL;DR: The phylogenetic relations of this bacterium, its distinct morphologic characteristics, and the unusual features of the disease are sufficient grounds for naming this bacillus Tropheryma whippelii gen. sp.
Abstract: Background. Whipple's disease is a systemic disorder known for 85 years to be associated with an uncultured, and therefore unidentified, bacillus. Methods. We used a molecular genetic approach to identify this organism. The bacterial 16S ribosomal RNA (rRNA) sequence was amplified directly from tissues of five unrelated patients with Whipple's disease by means of the polymerase chain reaction, first with broad-range primers and then with specific primers. We determined and analyzed the nucleotide sequence of the amplification products. Results. A unique 1321-base bacterial 16S rRNA sequence was amplified from duodenal tissue of one patient. This sequence indicated the presence of a previously uncharacterized organism. We then detected this sequence in tissues from all 5 patients with Whipple's disease, but in none of those from 10 patients without the disorder. According to phylogenetic analysis, this bacterium is a gram-positive actinomycete that is not closely related to any known genus. Conclu...

TL;DR: The Interactive Systems Framework for Dissemination and Implementation is presented, which provides a heuristic for understanding the needs, barriers, and resources of the different systems, as well as a structure for summarizing existing research and for illuminating priority areas for new research and action.
Abstract: If we keep on doing what we have been doing, we are going to keep on getting what we have been getting. Concerns about the gap between science and practice are longstanding. There is a need for new approaches to supplement the existing approaches of research to practice models and the evolving community-centered models for bridging this gap. In this article, we present the Interactive Systems Framework for Dissemination and Implementation (ISF) that uses aspects of research to practice models and of community-centered models. The framework presents three systems: the Prevention Synthesis and Translation System (which distills information about innovations and translates it into user-friendly formats); the Prevention Support System (which provides training, technical assistance or other support to users in the field); and the Prevention Delivery System (which implements innovations in the world of practice). The framework is intended to be used by different types of stakeholders (e.g., funders, practitioners, researchers) who can use it to see prevention not only through the lens of their own needs and perspectives, but also as a way to better understand the needs of other stakeholders and systems. It provides a heuristic for understanding the needs, barriers, and resources of the different systems, as well as a structure for summarizing existing research and for illuminating priority areas for new research and action.

Henry A. Giroux1
TL;DR: Giroux as discussed by the authors analyzes the major positions of these theories, finding them inadequate as a foundation for a critical science of schooling, and outlines the directions for a new theory of resistance and schooling which contains an understanding of how power, resistance, and human agency can become central elements in the struggle for social justice in schools and in society.
Abstract: In the past ten years radical educators have developed several theories around the notions of reproduction and resistance. In this article, Henry Giroux critically analyzes the major positions of these theories, finding them inadequate as a foundation for a critical science of schooling. He concludes by outlining the directions for a new theory of resistance and schooling which contains an understanding of how power, resistance, and human agency can become central elements in the struggle for social justice in schools and in society.
