Incorporation of Climate Change in Water Availability Modeling

Abstract: The state of Texas recently implemented a water-availability modeling (WAM) system to support planning and regulatory activities. River basin hydrology is represented in the WAM system by sequences of historical monthly naturalized streamflows and net reservoir evaporation rates. This paper describes a case study investigation of the potential effects of climate-change on assessments of water-supply capabilities and focuses on whether and how climate change considerations should be incorporated in the WAM system. A modeling approach was adopted to explore the impacts of climate change on hydrologic and institutional water availability for the numerous water users who depend on supplies provided by the 118,000 km2 Brazos River Basin. Analyses of historical naturalized streamflows indicate hidden but significant multiple-year cycles but no long-term trends during the twentieth century. A climate model and watershed hydrology model are used to adjust the WAM system hydrology to reflect anomalous climate duri...

Effect of Fish Size on the Filtering Efficiency and Selective Particle Ingestion of a Filter-Feeding Clupeid

Abstract: We developed a model predicting the filtering efficiency of different sizes of filter-feeding gizzard shad Dorosoma cepedianum. The model is based on the cumulative frequencies of interraker distances of the gill rakers and was corroborated by feeding trials in which gizzard shad ingested different sizes of suspended plastic microspheres and plankton. The proportion of particles removed by fish increased as a function of particle size, leveling off when particle diameters exceeded 35 μm for small fish (7.1–11.1 cm standard length, SL) and 55 μm for large fish (13.6–16.3 cm SL). According to selectivity index values computed from the filtering efficiency model, gizzard shad of 5, 15, and 25 cm SL would selectively feed on particles larger than 19, 40, and 63 μm, respectively. This change in selective particle ingestion may explain why phytoplankton becomes less important in the diet of gizzard shad and why this clupeid shifts its feeding niche as it increases in length.

The effect of assisted and resisted sprint training on acceleration and velocity in Division IA female soccer athletes.

Abstract: This investigation evaluated the effects of a 4-week, 12-session training program using resisted sprint training (RST), assisted sprint training (AST), and traditional sprint training (TST) on maximal velocity and acceleration in National Collegiate Athletic Association (NCAA) Division IA female soccer athletes (n = 27). The subjects, using their respective training modality, completed 10 maximal effort sprints of 20 yd (18.3 m) followed by a 20-yd (18.3 m) deceleration to jog. Repeated measures multivariate analyses of variance and analyses of variance demonstrated significant (p 15 yd; > 13.7 m) should use resisted sprint training protocols.

A Top Management Team's Reactions to Organizational Transformation: The Diagnostic Benefits of Five Key Change Sentiments

Abstract: From research dating to the 1940s, we identified five precursor sentiments deemed important by organizational scientists studying reactions of organizational change recipients. Collectively, these sentiments constitute a framework for understanding reactions to change. We investigated the validity and utility of the framework for assessing the progress of an organizational change by using it to guide the analysis of qualitative interview data collected from a top management team as part of an assessment of a major organizational change. We demonstrate that the five-sentiment framework provides a useful and reliable tool for coding interview responses. In addition, the data, thus coded, provided very useful insight into the underlying concerns regarding the change. We suggest that the five sentiment framework is a useful guide for diagnosing change progress and planning measures to correct change shortcomings.
