Quantifying temporal and spatial variations in sediment, nitrogen and phosphorus transport in stream inflows to a large eutrophic lake

High-frequency sampling of two major stream inflows to a large eutrophic lake (Lake Rotorua, New Zealand) was conducted to measure inputs of total suspended sediment (TSS), and fractions of nitrogen and phosphorus (P). A total of 17 rain events were sampled, including three during which both streams were simultaneously monitored to quantify how concentration–discharge (Q) relationships varied between catchments during similar hydrological conditions. Dissolved inorganic nitrogen (DIN) concentrations declined slightly during events, reflecting dilution of groundwater inputs by rainfall, whereas dissolved inorganic P (PO₄–P) concentrations were variable and unrelated to Q, suggesting dynamic sorptive behaviour. Event loads of total nitrogen (TN) were predominantly DIN, which is available for immediate uptake by primary producers, whereas total phosphorus (TP) loads predominantly comprised particulate P (less labile). Positive correlations between Q and concentrations of TP (and to a lesser extent TN) reflected increased particulate nutrient concentrations at high flows. Consequently, load estimates based on hourly Q during storm events and concentrations of routine monthly samples (mostly base flow) under-estimated TN and TP loads by an average of 19% and 40% respectively. Hysteresis with Q was commonly observed and inclusion of hydrological variables that reflect Q history in regression models improved predictions of TN and TP concentrations. Lorenz curves describing the proportions of cumulative load versus cumulative time quantified temporal inequality in loading. In the two study streams, 50% of estimated two-year loads of TN, TP and TSS were transported in 202–207, 76–126 and 1–8 days respectively. This study quantifies how hydrological and landscape factors can interact to influence pollutant flux at the catchment scale and highlights the importance of including storm transfers in lake loading estimates

Impact of Computer-Based Peer Review on College Students’ Performance and Perceived Self-Efficacy in an Online Graphic Design Course

Prior research has indicated that the incorporation of computer-based peer review into writing instruction increases student engagement, improves student performance, and increases student perceptions of self-efficacy. This study used a quasi-experimental untreated control group design to examine the impact of computer-based peer review on student performance and perceived self-efficacy in an undergraduate agricultural graphic design course. The impact of participation in computer-based peer review on performance scores was investigated using a MANOVA. After two rounds of peer review, students improved their overall course performance by one-half letter grade. Perceptions of self-efficacy were further analyzed using a one-way repeated measures ANOVA. Most (54.17%) students who participated in the computer-based peer review process reported increases in perceived self-efficacy in graphic design. The findings from this study indicate the benefits of computer-based peer review extend to instruction in graphic design courses
