Changes in sugar, protein, respiration, and ethylene in developing and harvested Geraldton waxflower (Chamelaucium uncinatum) flowers

Sugar and protein levels and rates of respiration and ethylene production were measured for Geraldton waxflower (Chamelaucium uncinatum) flowers in order to characterise flower development and senescence in this cut flower crop. Ten sequential stages of floral development were identified. Sugar levels increased during bud development, the highest concentrations (c. 130 mg sucrose equivalents/g dry weight (DW) being measured during the nectiferous stages of flower opening. There was little variation in either soluble or insoluble protein levels during flower development, levels averaging around 19 and 25 mg bovine serum albumin (BSA) equivalents/g DW, respectively. In flowers cut and maintained individually, sugar and protein levels decreased rapidly after harvest, suggesting their use as respiratory substrates. Sprig senescence was characterised by loss in fresh weight and decreasing water use. In flowers taken from sprigs in vases, sugar and protein levels increased slightly (Day 4) before decreasing with senescence (Day 8). Flowers on sprigs appeared to deteriorate at c. 8 days after harvest, in concert with the decreasing sugar and protein levels. Respiration rates were initially high (1432 ml/kg per h) for the flowers from harvested sprigs, and declined during vase life. Ethylene production also decreased during vase life from an initial level of 1.32 mu l/kg per h. The absence of respiratory and ethylene production peaks indicates that Geraldton waxflower flowers are nonclimacteric in nature

Initial psychometric evaluation of the Wayfinding Effectiveness Scale

This study evaluates three versions of the Wayfinding Effectiveness Scale (WES), developed to differentiate problems of wayfinding and wandering behavior of community-residing elders with dementia (EWD), in 266 dyads (EWD and caregiver) recruited from Alzheimer's Association chapters. Factor analyses yield a five-factor solution (explained variance = 62.6%): complex wayfinding goals, analytic strategies, global strategies, simple wayfinding goals, and being stimulus bound. Overall, internal consistencies are high: WES (.94-.95), and subscales are stable across all versions. Testretest reliability is acceptable for the overall WES and two subscales (complex and simple wayfinding goals) for the care recipient current behavior version. Construct validity is supported by the pattern of correlations among subscales and analyses of variance (ANOVAs) showing significant differences among the care recipient (current vs. prior behavior) and caregiver versions overall and for all subscales. Results support the WES as a valid and reliable measure of wayfinding effectiveness in persons with dementia
