Sound is an inherent component of the environment that provides conditions and information necessary for many animal activities. Soniferous species require specific acoustic and physical conditions suitable for their signals to be transmitted, received, and effectively interpreted to successfully identify and utilize resources in their environment and interact with conspecifics and other heterospecific organisms. We propose the Acoustic Habitat Hypothesis to explain how the acoustic environment influences habitat selection of sound-dependent species. We postulate that sound-dependent species select and occupy habitats (...) with unique acoustic characteristics that are essential to their functional needs and conducive to the threshold of sound frequency they produce and detect. These acoustic habitats are based on the composition of biophony, geophony, and technophony in the soundscape and on the biosemiotics mechanisms described in the eco-field hypothesis. The Acoustic Habitat Hypothesis initiates questions of habitat selection that go beyond the physical attributes of the environment by applying ecoacoustics theory. We outline the theoretical basis of the Acoustic Habitat Hypothesis and provide examples from the literature to support its assumptions. The concept of acoustic habitats has been documented in the literature for many years but here, we accurately and extensively define acoustic habitat and we put this concept into a unified theory. We also include perspectives on how the Acoustic Habitat Hypothesis can stimulate a paradigm shift in conservation strategies for threatened and endangered species. (shrink)

The paper reviews the current situation regarding a new theory of brain dynamics put forward by the authors in an earlier publication. Motivation for the theory is discussed in terms of two issues: the long-standing problem of accounting for the stability and nonlocal properties of memory, and the experimental and theoretical evidence against the classical theory of brain action. It is shown that the new theory provides an explanation and a conceptually unifying framework for phenomena of brain action that resist (...) classical explanation. Further independent experiments provide strong additional support for the theory. The fact that this theory incorporates quantum mechanisms in an essential way is considered to be of wide scientific interest in view of the unique status of the brain in relation to the physical, biological, and mental orders in nature.

While the bioethics literature demonstrates that the field has spent substantial time and thought over the last four decades on the goals, methods, and desired outcomes for service and training in bioethics, there has been less progress defining the nature and goals of bioethics research and scholarship. This gap makes it difficult both to describe the breadth and depth of these areas of bioethics and, importantly, to gauge their success. However, the gap also presents us with an opportunity to define (...) this scope of work for ourselves and to help shape the broader conversation about the impact of academic research. Because of growing constraints on academic funding, researchers and scholars in many fields are being asked to demonstrate and also forecast the value and impact of their work. To do that, and also to satisfy ourselves that our work has meaningful effect, we must understand how our work can motivate change and how that change can be meaningfully measured. In a field as diverse as bioethics, the pathways to and metrics of change will likewise be diverse. It is therefore critical that any assessment of the impact of bioethics research and scholarship be informed by an understanding of the nature of the work, its goals, and how those goals can and ought to be furthered. In this paper, we propose a conceptual model that connects individual bioethics projects to the broader goals of scholarship, describing the translation of research and scholarly output into changes in thinking, practice, and policy. One of the key implications of the model is that impact in bioethics is generally the result of a collection of projects rather than of any single piece of research or scholarship. Our goal is to lay the groundwork for a thoroughgoing conversation about bioethics research and scholarship that will advance and shape the important conversation about their impact. (shrink)
