Little Variance (little + variance)
Selected AbstractsSEAWEED ABUNDANCE AND DIVERSITY IN HIGH ENERGY AND LOW ENERGY AREAS AT PORT ARANSAS, TEXAS JETTIESJOURNAL OF PHYCOLOGY, Issue 3 2001Article first published online: 24 SEP 200 Agan, J. C. & Lehman, R. L. Department of Physical and Life Sciences, Texas A&M University-Corpus Christi 6300 Ocean Dr., Corpus Christi, TX 78412 USA Benthic algal sampling from high and low energy zones at a selected site on the south jetty at Port Aransas, Texas was completed between April 1999 and February 2000. Species composition and seasonal periodicity in relation to temperature and salinity fluctuations were determined. Dominant plants throughout the year included Bryocladia cuspidata, Bryocladia thyrsigera, Gelidium pusillum, Centroceras clavulatum, Ulva fasciata, and Padina gymnospora. The Rhodophyta dominated species coverage, along with biomass accumulation, although Chlorophyta species accrued the greatest biomass on the high energy side in April and June sampling. Chlorophyta are important to benthic coverage and biomass in the shallowest of waters, despite being fewer in species richness. Phaeophyta species including Petalonia fascia, Hincksia mitchelliae, and Ectocarpus siliculosus were found only during the cooler months. Padina gymnospora was the one exception as it was collected year-round. Results indicate that a greater Rhodophyta abundance was found on the channel side (low energy), where as, the surf side (high energy) contained a greater Chlorophyta abundance. Phaeophyta abundance for both high and low energy sites were comparable possibly due to the greater depth of water in which they are located. Little variance occurred in average biomass accumulation throughout the year. Highest biomass was in August (216.613g dry weight) with lowest occurring in April (107.4205g dry weight).

One reason for this disparity might be that children's experiences are shaped more by the circumstances in which they are fostered than by merely being raised away from their parents. This article examines how fostered children in one urban community in northwestern Cameroon spend time relative to their nonfostered peers and, by grouping fostered children according to fostering circumstances, how they spend time relative to one another. Analysis of children's activities suggests little variance between the experiences of fostered and nonfostered children, but significant differences among fostered children. These results are interpreted using children's views of activities, and the potential consequences of children's relative integration in foster households are discussed. [source] INITIAL LEVELS OF DIFFERENTIATION AND REDUCTION IN PSYCHOLOGICAL SYMPTOMS FOR CLIENTS IN MARRIAGE AND FAMILY THERAPYJOURNAL OF MARITAL AND FAMILY THERAPY, Issue 1 2005Suzanne Bartle-Haring Using Bowen Family Systems Theory as a theoretical underpinning, in this study, we investigated the hypothesis that clients with higher levels of differentiation would improve more quickly in therapy than clients with lower levels of differentiation. Hierarchical Linear Modeling was used to analyze the data over nine sessions of therapy in a sample from an on-campus training clinic. The results suggest that there was variation in the initial levels of psychological symptoms and that differentiation was a significant predictor of this variance. The results also suggest that although psychological symptoms decreased over the nine sessions of therapy, there was very little variance in this change. These results are discussed in relation to Bowen Theory. The difficulties of doing this type of research and the lessons learned from this project are also discussed. [source] | ||||||||||
