BACKGROUND Falls are common among elderly people, and the risk increase with age. Falls are associated with both health and social consequences for the patient, and major societal costs. Identification of risk factors should be investigated to prevent falls. Previous studies have shown anemia to be associated with increased risk of falling, but the results are inconsistent. The aim of this stud...

OBJECTIVE This study examined adherence to home modification recommendations made by an occupational therapist and attempted to identify predictors of adherence. METHOD An experienced occupational therapist visited the homes of 178 people (mean age = 764 years) to evaluate for and recommend appropriate home modifications for falls prevention. One year later, a research assistant visited these...

The magnitude, frequency, duration, timing, and rate of change of hydrologic conditions regulate ecological processes in aquatic ecosystems. Conditions are typically characterized using annual-based hydrologic indices derived from daily and/or monthly stream flow data. In this study, we present an alternative approach to identify hydrologic indices based on storm hydrographs. Hydrologic indices...

The present study considers whether coarticulation in production and its relationship to categorization could provide a synchronic basis for the prevalence of sound change in unstressed syllables. The size of V2-on-V1 coarticulation in the production of /pV1pV2l/ non-words (V1 = /U,Y/ and V2 = /e, o/) produced by German speakers and with stress falling either on the first or second syllable was...

The effect of temporal asymmetry on amplitude modulation detection was studied using sawtooth modulators with rising (ramped) or falling (damped) temporal envelopes within each period of modulation. For pure-tone carriers, damped modulation was more detectable than ramped modulation for a 5-kHz carrier (by a threshold difference of 3.2 dB on average) but not for a 1-kHz carrier. The threshold d...

BACKGROUND Accident and Emergency (A and E) is the first port of call for most people who have experienced an injurious fall. This provides the potential for identifying patients who may benefit from preventative interventions. This study aims to estimate the percentage of falls attendances that are not recorded on computerised A and E records. METHODS A retrospective cohort study design was ...

The mortality impacts of the HIV epidemic in sub-Saharan Africa are profound adult mortality has doubled or trebled even in communities in which prevalence remains below 10 per cent (Timaeus, 1998; Boerma and others, 1998), and life expectancy in many countries is falling rapidly. The social and demographic consequences of this unprecedented mortality increase have been the main focus of demogr...

(1) Each pair of points can be joined by one and only one straight line segment. (2) Any straight line segment can be indefinitely extended in either direction. (3) There is exactly one circle of any given radius with any given center. (4) All right angles are congruent to one another. (5) If a straight line falling on two straight lines makes the interior angles on the same side less than two ...
