Monitoring of water clarity trends is necessary for water resource managers. Remote sensing based methods are well suited for monitoring clarity in water bodies such as the inland lakes in Minnesota, United States. This study evaluated the potential of using imagery from NASA’s MODIS sensor to study intra-annual variations in lake clarity. MODIS reflectance images from six dates throughout the ...

Changes in water clarity across the shallow continental shelf of the central Great Barrier Reef were investigated from ten years of daily river load, oceanographic and MODIS-Aqua data. Mean photic depth (i.e., the depth of 10% of surface irradiance) was related to river loads after statistical removal of wave and tidal effects. Across the ∼25,000 km(2) area, photic depth was strongly related to...

We build on principles from interdependence theory and evolutionary psychology to propose that forgiving bolsters one's self-respect and self-concept clarity if the perpetrator has acted in a manner that signals that the victim will be safe and valued in a continued relationship with the perpetrator but that forgiving diminishes one's self-respect and self-concept clarity if the perpetrator has...

AIMS The aim of this paper is to operationalize the principle-based method of concept analysis. BACKGROUND While nursing has embraced the use of concept analysis as a valid and significant entree into an area of research, methodological development has created strategies of inquiry that vary in purpose and in the nature of their findings. DISCUSSION We propose that, as the primary utility o...

In any research project, categorising responses for interpretation is a crucial step. This involves the reduction of the complexity of a data set and allows clarity of interpretation. In structured techniques, the researcher often determines or assumes the nature of the categories in advance, and respondents are then asked to choose one from a range of provided options (e.g., Yes/No; a point on...

The current research had 2 aims: (1) to determine the cross-sectional age differences in self-concept clarity during adulthood and (2) to examine the importance of social role experiences for age differences in self-concept clarity. These aims were addressed in 2 large samples of adults ranging in age from 18 to 94 years. In both studies, self-concept clarity had a curvilinear relation to age s...
