TL;DR: In this paper, the authors used a distributed hydrological model, MIKE SHE, by using bi-criteria (i.e., two measurable variables, streamflow and water table depth) to describe a forested watershed that is characteristic of the lower Atlantic Coastal Plain.
Abstract: . Hydrological models are important tools for effective management, conservation and restoration of forested wetlands. The objective of this study was to test a distributed hydrological model, MIKE SHE, by using bi-criteria (i.e., two measurable variables, streamflow and water table depth) to describe the hydrological processes in a forested watershed that is characteristic of the lower Atlantic Coastal Plain. Simulations were compared against observations of both streamflow and water table depth measured on a first-order watershed (WS80) on the Santee Experimental Forest in South Carolina, USA. Model performance was evaluated using coefficient of determination (R2) and Nash-Sutcliffe's model efficiency (E). The E and root mean squared error (RMSE) were chosen as objective functions for sensitivity analysis of parameters. The model calibration and validation results demonstrated that the streamflow and water table depth were sensitive to most of the model input parameters, especially to surface detention storage, drainage depth, soil hydraulic properties, plant rooting depth, and surface roughness. Furthermore, the bi-criteria approach used for distributed model calibration and validation was shown to be better than the single-criterion in obtaining optimum model input parameters, especially for those parameters that were only sensitive to some specific conditions. Model calibration using the bi-criteria approach should be advantageous for constructing the uncertainty bounds of model inputs to simulate the hydrology for this type of forested watersheds. R2 varied from 0.60–0.99 for daily and monthly streamflow, and from 0.52–0.91 for daily water table depth. E changed from 0.53–0.96 for calibration and 0.51–0.98 for validation of daily and monthly streamflow, while E varied from 0.50–0.90 for calibration and 0.66–0.80 for validation of daily water table depth. This study showed that MIKE SHE could be a good candidate for simulating streamflow and water table depth in coastal plain watersheds.

TL;DR: In this article, the authors examined how outstanding high school football coaches developed life skills in their players and found that they did not view the coaching of life skills as separate from their general coaching strategies for performance enhancement.
Abstract: This study examined how outstanding high school football coaches developed life skills in their players. In-depth phone interviews were conducted with 10 outstanding coaches ranging in age from 47 to 68 years (M = 54). Coaches averaged 31 years of coaching experience, and were highly successful (76.6% winning percentage). Hierarchical content analysis of the data revealed that two general dimensions or categories of strategies emerged: (a) general coaching; and (b) player development strategies. Within the general coaching strategies dimension, higher-order themes focused on working with players and strategies for dealing with other parties. In the player development strategies general dimension was the higher-order theme set of teaching life skills. Results highlighted that it was clear these coaches did not view the coaching of life skills as separate from their general coaching strategies for performance enhancement and while highly motivated to win, personal development of their players was a top prio...

TL;DR: In this paper, the authors address the contradiction between the conceptualization of partner violence as almost exclusively perpetrated by men and over 200 studies with data on both men and women which found "gender symmetry," i.e., that about the same percentage of women as men physically assault a partner.

TL;DR: The Peat Decomposition Model (PDM) as mentioned in this paper is a new model of long-term peat accumulation, which considers two vegetation types, vascular and nonvascular, with different decomposition rates and aboveground and belowground litter input rates.
Abstract: To test the hypothesis that long-term peat accumulation is related to contemporary carbon flux dynamics, we present the Peat Decomposition Model (PDM), a new model of long-term peat accumulation. Decomposition rates of the deeper peat are directly related to observable decomposition rates of fresh vegetation litter. Plant root effects (subsurface oxygenation and fresh litter inputs) are included. PDM considers two vegetation types, vascular and nonvascular, with different decomposition rates and aboveground and belowground litter input rates. We used PDM to investigate the sensitivities of peat accumulation in bogs and fens to productivity, root:shoot ratio, tissue decomposability, root and water table depths, and climate. Warmer and wetter conditions are more conducive to peat accumulation. Bogs are more sensitive than fens to climate conditions. Cooler and drier conditions lead to the lowest peat accumulation when productivity is more temperature sensitive than decomposition rates. We also compare peat age–depth profiles to field data. With a very general parameterization, PDM fen and bog age–depth profiles were similar to data from the the most recent 5000 years at three bog cores and a fen core in eastern Canada, but they overestimated accumulation at three other bog cores in that region. The model cannot reliably predict the amount of fen peat remaining from the first few millennia of a peatland's development. This discrepancy may relate to nonanalogue, early postglacial climatic and nutrient conditions for rich-fen peat accumulation and to the fate of this fen peat material, which is overlain by a bog as the peatland evolves, a common hydroseral succession in northern peatlands. Because PDM sensitivity tests point to these possible factors, we conclude that the static model represents a framework that shows a consistent relationship between contemporary productivity and fresh-tissue decomposition rates and observed long-term peat accumulation.
