Theoretical Considerations

The Delta and Yanert caribou (Rangifer tarandus granti) herds apparently maintained discrete calving areas from 1979 through 1983 (as determined by radio telemetry studies), even though substantial intermixing occurred during other seasons. Also, the Delta herd apparently used a single traditional calving area from the 1950's through 1983, based on results of aerial surveys and 1979-83 telemetry studies. Calving distribution in 1984 changed dramatically; 5 of 25 radio-collared Delta herd cows ^3 years old and 5 of 24 radio-collared Delta herd cows <3 years old were located in the calving area of the Yanert herd, 72 km west-southwest of the traditional Delta herd calving area. Use of traditional, separate calving areas resumed for the two herds in 1985. One implication of these data is that the current definition of a caribou herd may not always apply. A second implication is that current models of caribou socioecology, based largely on the concepts of traditional use of calving grounds, herd identity/fidelity, and dispersal, inadequately predict or explain all empirical observations. An evolving model of optimal and dynamic use of space can help refine current models of caribou socioecology.

Evidence for the fidelity of female barren-ground caribou (Rangifer tarandus spp.) of each herd to specific calving grounds is convincing. Involvement of learned behaviour in the annual return of those cows to the same calving grounds implies such actions are a form of «traditional» behaviour. Even wide variations in population size have not yet knowingly led to marked changes in size or location of calving grounds or prolonged abandonment of established ones. Rarely is the adoption of new calving grounds reported and emigration to another herd's calving ground or interchange between calving grounds has not yet been unequivocally documented. The calving experience of individual caribou and environmental pressures may modify the cow's use patterns of her calving grounds. The current definition of herds based on traditional calving grounds may require modification, if increasing caribou numbers result in changes in traditions. However, current data do not contradict either the fidelity to traditional calving grounds or the concept of herd identity based on that fidelity.

<p>Recent studies of woodland caribou (Rangifer tarandus caribou) in northern Quebec and central Labrador have demonstrated similar patterns of seasonal movements and distribution among four herds. Aerial surveys and radio-telemetry indicated that animals occupied forest-wetland habitat at densities of 0.03 caribou km2, or lower, for most of the year. Although females were widely dispersed at calving individuals demonstrated fidelity toward specific calving locations, in successive years. Caribou did not form large post-calving aggregations. Movement was greatest in the spring, prior to calving, and in the fall, during or immediately after rutting. Caribou were generally sedentary during summer and winter, although some moved relatively long distances to late-winter range. Although the herds occupy continuous range across Quebec and Labrador, our data indicate that the herds are largely discreete and should be managed individually.</p>

The current definition of a conditional probability enables one to update probabilities only on the basis of stochastic information. This paper provides a definition for conditional probability with non-stochastic information. The definition is derived by a set of axioms, where the information is connected to the outcome of interest via a loss function. An illustration is presented.

Mechanical Momentum

It is known since Madelung that the Schr&ouml;dinger equation can be thought of as governing the evolution of an incompressible fluid, but the current theory fails to mathematically express this incompressibility in terms of the wavefunction without facing problem. In this paper after showing that the current definition of quantum-mechanical momentum as a linear operator is neither the most general nor a necessary result of the de Broglie hypothesis, a new definition is proposed that can yield both a meaningful mathematical condition for the incompressibility of the Madelung fluid, and nonlinear generalisations of Schr&ouml;dinger and Klein-Gordon equations. The derived equations satisfy all conditions that are expected from a proper generalisation: simplification to their linear counterparts by a well-defined dynamical condition; Galilean and Lorentz invariance (respectively); and signifying only rays in the Hilbert space.

Shed Light

Purpose In the field of audiology, auditory processing disorder (APD) continues to be a topic of ongoing debate for clinicians and scientists alike, both in terms of theory and clinical practice. In the current viewpoint, we first lay out the main issues that are central to the controversy surrounding APD, and then suggest a framework toward their resolution. Method The current viewpoint is informed by reviewing existing studies in the field of APD to better understand the issues contributing to the controversies in APD. Results We found that, within the current definition of APD, the two main issues that make the APD diagnosis controversial are (a) comorbidity with other disorders and (b) the lack of domain specificity. These issues remain unresolved, especially with the use of the existing behavioral APD test batteries. In this viewpoint, we shed light on how they can be mitigated by implementing the administration of an objective, physiological test battery. Conclusions By administering an objective test battery, as proposed in this viewpoint, we believe that it will be possible to achieve a higher degree of specificity to the auditory domain that will not only contribute towards clinical practice but also contribute towards strengthening APD as a theoretical construct.

In this chapter, we bring everything together and provide guidance on how educators and game designers can facilitate productive family engagement around video games. We discuss activity structures we designed and tested in after school and home environments that help connect school, home, and community learning. We also draw upon two design-based research projects to examine how to develop video games for families that expand the current definition of “family-friendly games.”

This chapter briefly identifies important societal events and governmental responses that set the stage for the emergence of the specialty of police psychology, provides the names and departments of early practitioners (1963-1990) of police psychology, and explains how the current definition of police psychology was developed, with its four domains and 55 proficiencies. The maturation of the specialty is outlined from its recognition as an American Psychological Association (APA) proficiency, to the creation of an American Board of Police & Public Safety Psychology (ABPPSP) specialty board, and most recently to its recognition as an APA specialty.

The most common definition of literacy is the ability to read and write. However, for teachers working with multilingual learners, the development of literacy skills is much more complex than this simple definition would suggest. Notions of literacy in the 21st century have evolved in response to a number of societal changes, such as globalization, large-scale human migration, and advances in digital technologies. This chapter considers how these societal changes have influenced conceptions and practices of literacy. It provides a brief overview of some important theoretical considerations that inform understandings of literacy development for multilingual learners, including critical literacy, multiliteracies, multimodal literacy, and translanguaging, and explores current conceptions of literacy to help second and foreign language (SFL) teachers better understand how to meet the literacy needs of multilingual learners in the 21st century, offering practical suggestions for teaching from a multiliteracies perspective.
