Whether a rigid body limits maneuverability depends on how maneuverability is defined. By the current definition, the minimum radius of the turn, a rigid-bodied, spotted boxfish Ostracion meleagris approaches maximum maneuverability, i.e. it can spin around with minimum turning radii near zero. The radius of the minimum space required to turn is an alternative measure of maneuverability. By this definition, O. meleagris is not very maneuverable. The observed space required by O. meleagris to turn is slightly greater than its theoretical minimum but much greater than that of highly flexible fish. Agility, the rate of turning, is related to maneuverability. The median- and pectoral-fin-powered turns of O. meleagris are slow relative to the body- and caudal-fin-powered turns of more flexible fish.

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.

In the current definition, the budget is a financial plan by means of which the shares of all relevant resources related to achieving an objective within a certain organisational subdivision are provided in the financial expression. The budget is the result of the budgeting activity that is characterised by: planning and coordinating, authority and responsibility, communication, control, etc. Any budget meets several functions and namely: prediction, control, providing the financial balance, etc. Budgeting the company’s activity involves preparing of budgets related to its functions, namely: the budget of production that includes the manufacturing budget, the budget related to machines and equipment, the budget related to the labour force, the budget of raw materials and consumables, the overall production budget, the commercial budget, meaning the seller’s budget, the budget of sales managers, the commercial manager’s budget, the commercial budget itself, the budget of the investments by emphasising the budget of the commercial and industrial investments, the budget of the research-development activity by emphasising the expenses related to this activity, the budget of treasury, meaning the budget of revenues, the budget of payments and correlation between them, etc. In the activity of the company’s manager, applying the management by budgets involves going through several stages: sizing the objectives in financial form, preparing the system of budgets at the company’s level by fields, organising the information system related to budgets, the control of budgetary system, etc.

It is known since Madelung that the Schrödinger 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 Schrödinger 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.

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.
