The aim of this study was to compare whole and segmental body composition and bone mineral density of collegiate American football players by playing positions. Forty collegiate American football players voluntarily participated in this study. Participants were categorized by playing positions into one of five categories i.e., defensive linemen, offensive linemen, defensive secondary players, o...

This book chapter reviews some of the major principles associated with optimal strategy in basketball. In particular, we consider the principles of allocative efficiency (optimal allocation of shots between offensive options), dynamic efficiency (optimal shot selection in the face of pressure from the shot clock), and the risk/reward tradeoff (strategic manipulation of outcome variance). For ea...

Offensive language has arisen to be a big issue to the health of both online communities and their users. To the online community, the spread of offensive language undermines its reputation, drives users away, and even directly affects its growth. To users, viewing offensive language brings negative influence to their mental health, especially for children and youth. When offensive language is ...

Research suggesting that disgust has a role in psychiatric illness has emerged (Phillips et al, 1998). Although a well-developed theory of disgust exists in the literature (Rozin & Fallon, 1987), it does not indicate how extreme disgust reactions relate to psychopathology. Briefly, disgust is readily distinguished from other emotions, has robust behavioural correlates such as avoidance and dist...

An offensive alliance in a graph Γ = (V,E) is a set of vertices S ⊂ V where for every vertex v in its boundary it holds that the majority of vertices in v’s closed neighborhood are in S. In the case of strong offensive alliance, strict majority is required. An alliance S is called global if it affects every vertex in V \S, that is, S is a dominating set of Γ. The offensive alliance number ao(Γ)...

For a graph G = (V,E), a non-empty set S ⊆ V is a global offensive alliance if for every v ∈ V − S, at least half of the vertices from the closed neighborhood of v are in S. A set S ⊆ V is a global strong offensive alliance if for each vertex v ∈ V −S, a strict majority of the vertices of the closed neighborhood of v are in S. The cardinality of a minimum global (strong) offensive alliance of a...

this paper highlights the folk perception of impoliteness among ghanaians in view of watts’ (2003) notion of first order impoliteness. the study showed that impoliteness is not just an opposite of politeness, but the manifestation of non-cooperation, disapproval, and mutual antipathy through certain communicative behaviours that signal disrespect. these communicative behaviours include ‘interru...

BACKGROUND Shoulder injuries remain one of the most common injuries among collegiate football athletes. Offensive linemen in particular are prone to posterior labral pathology. PURPOSE To evaluate the efficacy of shoulder bracing in collegiate offensive linemen with respect to injury prevention, severity, and lost playing time. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Offe...
