Introducing a Practitioner-focused Publication in Exercise Science and Kinesiology

The purpose is to introduce Topics in Exercise and Science Kinesiology (TESK) as an outlet for practical information. We searched available journals in the field to determine practitioner-focused options, we also determined the percentage of presented abstracts at a popular meeting compared to the number of published papers in a leading peer-reviewed scientific journal. Point of application 1: Only 2% of publication options in kinesiology or exercise science have a practitioner focus. Point of application 2: A relatively small number of peer-reviewed conference abstracts (less than 10%) are deemed publication-worthy following journal peer-review. Point of application 3: To be more inclusive, we announce the International Community of Scholars in Kinesiology (ICSK); and to provide students with important information on professional development and trending research, we will host a virtual Student Research Week each year

Day of Launch Profile Selection for Pad Abort Guidance

A day of launch selection approach that involves choosing from an array of pitch profiles of varying loft was analyzed with the purpose of reducing the risk of a land landing failure during a pad abort. It was determined that selecting from three pitch profiles can reduce the number of waterline abort performance requirement failures approximately in half without compromising other performance metrics

Improved Estimates of Tributary Nitrogen Load to Casco Bay, Maine

Over the past two decades, total nitrogen (TN) concentrations have increased in Casco Bay (CBEP 2015). The sources of the increased nitrogen are poorly understood but occur with simultaneous population growth and land use changes. The total riverine nitrogen load to Casco Bay was previously estimated by Liebman and Milstead (2012) using the United States Geologic Survey’s (USGS) SPAtially Referenced Regression On Watershed attributes (SPARROW) model. The SPARROW model uses watershed characteristics, regional monitoring data and nitrogen source data to estimate nitrogen loading but was not validated using measurements of nitrogen in the Casco Bay watershed. This study attempts to estimate the nitrogen load from three rivers (Presumpscot, Royal and Capisic Brook), that together account for 78% of Casco Bay’s watershed (87% of the freshwater flow) and generally represent two distinct types of sub basins in the larger watershed (i.e., forested and urban) (Liebman and Milstead 2012). The TN loading estimates from the three rivers were then extrapolated to provide an estimate for the total riverine load to Casco Bay and compared to the previously modeled TN load estimates. Additionally, the riverine TN load was compared to other known TN loads from the other major sources such as atmospheric deposition, combined sewage outfalls (CSO) and waste water treatment facility (WWTF) effluent. Loading estimates for the three rivers were based on discharge and nitrogen concentration data from June 2017 – May 2018. We used Presumpscot River discharge from USGS gauge 01064118 near Westbook, Maine. Discharge for the Royal River was estimated using a historic watershed yield relationship with the nearby Sheepscot River which is still gauged. Capisic Brook discharge was estimated using the USGS Streamstats model. Water samples were collected at least monthly with an attempt to collect at both high and low flows. Water samples were analyzed for TN, Nitrate/Nitrite, and Ammonium. Water samples were not collected from December – March; concentrations for that time period are based on a discharge-concentration relationship, if present, or are assumed to be the average concentration of all data. Collectively, the rivers in this study load less TN than is discharged by the area’s five largest WWTFs. Presumpscot River, while loading the greatest total mass of nitrogen (173 Mg N yr-1), loads the least per hectare (1.16 kg ha-1). Capisic Brook loads the most total nitrogen per hectare (7.71 kg N ha-1) and Royal River loads more nitrogen than Presumpscot but less than Capisic (3.79 kg N ha-1). Land use is correlated with the mass of nitrogen per hectare exported via the rivers. For example, Capisic Brook has the greatest percentage of developed land use types followed by Royal then Presumpscot. For comparison, if we assume the WWTF’s discharge to their permit limit, the total nitrogen load from these three rivers accounts for less than half of the total nitrogen mass discharged into Casco Bay from WWTFs (902 Mg N yr-1). This study’s findings suggest that while non-point loading from river systems in Casco Bay contribute to the nitrogen content in the bay, they load less nitrogen than the areas of WWTFs. The amount of developed and agricultural land is correlated with the amount of nitrogen delivered to the bay by a river, which means that population growth will increase diffuse and point source loading in the future. And finally, this study’s estimates are in fair agreement with SPARROW’s TN loading estimate. More specifically, all estimates are within the same order of magnitude, but SPARROW’s estimates are a factor of two greater for the Presumpscot River and Capisic Brook. This study represents an important first step in understanding nitrogen loading to Maine’s most populous watershed and can be used to prioritize management of the largest nitrogen sources

The leadership of entrepreneurialism in technical and further education colleges

The provision of vocational education and training is largely provided by the Technical and Further Education (TAFE) colleges and institutes, which have been established throughout Australia. All of these colleges and institutes are the responsibility of the respective State governments and are generally considered by those governments as strategic instruments of government particularly in regard to the preparation of people for employment and addressing deficiencies within the workforce. As more emphasis has been placed upon government entities to be more entrepreneurial and corporate in their outlook, pressures for reform of the TAFE sector have also increased. These pressures have included changes to funding arrangements, increased compliance regimes and a freeing of the training delivery to encourage the establishment of private providers. This thesis explores how Chief Executive Officers and Middle Level Managers within the TAFE environment are responding to those challenges. Forty-seven senior TAFE managers are interviewed to ascertain their perspectives on the community and government expectations of TAFE and how they believe TAFE is reacting to these challenges. Resulting from the research has been the emergence of entrepreneurship in TAFE. The notion of entrepreneurship in TAFE seems to capture a sense of change, a sense of emerging vibrance, and is often used to describe innovation and risk taking within the TAFE environment. The word entrepreneurial, entrepreneurialism, entrepreneurship and other derivations of the word are loosely employed by TAFE personnel to describe particular phenomenon within TAFE. Within this thesis the treatment of entrepreneurship as a definitive concept is recognised as problematic and it is therefore treated in a way that aligns to the TAFE environment and not necessarily as defined by traditional entrepreneurial theory.The resulting research has found that TAFE leaders are working in an environment that has a multiplicity of expectations and demands that challenge the leadership of TAFE. The research finds that many of the TAFE leaders strive to act entrepreneurially whilst attempting to manage an environment that is constrained by its policy frameworks, industrial relations requirements, funding arrangements and national and state compliance frameworks. The research questions whether governments should provide TAFE with greater capacity to act entrepreneurially; governments might, as a result be rewarded through greater achievements from the TAFE sector. While the research points to a number of highly successful leaders and leadership practices in TAFE it has also found that many leaders seem to rely upon intuitiveness and past experience to lead within their environments. Finally the research posits a framework for leadership within TAFE where the leadership styles of emotional intelligence, path-goal and leader-member exchange (LMX) are merged and integrated to provide a comprehensive quality leadership framework that will achieve positive outcomes: A framework that seeks to provide a practical guide to future leadership training and development in TAFE. In addition to the leadership framework the research has identified a number of intrinsic transformational drivers and extrinsic transformational drivers, which contribute to the success of leadership in TAFE and similarly a number of impediments, which restrict TAFE leaders

Improved sampling of the pareto-front in multiobjective genetic optimizations by steady-state evolution: a Pareto converging genetic algorithm

Previous work on multiobjective genetic algorithms has been focused on preventing genetic drift and the issue of convergence has been given little attention. In this paper, we present a simple steady-state strategy, Pareto Converging Genetic Algorithm (PCGA), which naturally samples the solution space and ensures population advancement towards the Pareto-front. PCGA eliminates the need for sharing/niching and thus minimizes heuristically chosen parameters and procedures. A systematic approach based on histograms of rank is introduced for assessing convergence to the Pareto-front, which, by definition, is unknown in most real search problems. We argue that there is always a certain inheritance of genetic material belonging to a population, and there is unlikely to be any significant gain beyond some point; a stopping criterion where terminating the computation is suggested. For further encouraging diversity and competition, a nonmigrating island model may optionally be used; this approach is particularly suited to many difficult (real-world) problems, which have a tendency to get stuck at (unknown) local minima. Results on three benchmark problems are presented and compared with those of earlier approaches. PCGA is found to produce diverse sampling of the Pareto-front without niching and with significantly less computational effort

Determination of Fluoride by Precipitation of Lead Chlorofluoride: Comparison of Classical and Homogeneous Precipitation Methods

Optimal conditions for the homogeneous precipitation of lead chlorofluoride were investigated and the method was compared with the classical procedure. The most suitable reagent for the pH control of the homogeneous solution was found to be urea \\u27.ith ammonium acetate buffer. If the precipitate obtained by both procedures was allowed to stand overnight, homogeneous precipitation resulted with more accurate data

Applications of satellite data relay to problems of field seismology

A seismic signal processor was developed and tested for use with the NOAA-GOES satellite data collection system. Performance tests on recorded, as well as real time, short period signals indicate that the event recognition technique used is nearly perfect in its rejection of cultural signals and that data can be acquired in many swarm situations with the use of solid state buffer memories. Detailed circuit diagrams are provided. The design of a complete field data collection platform is discussed and the employment of data collection platforms in seismic network is reviewed

Early-Morning and Late-Night Maximal Runs: Metabolic and Perceived Exertion Outcomes

People may exercise at the ends of their day to fit activity into their schedule; the purpose of this investigation was to determine if metabolic or perceived exertion outcomes differed between maximal runs early in the morning and late at night. After consuming a standardized, glucose drink, thirteen recreationally active individuals completed an early-morning and a late-night run on the treadmill while researchers measured metabolic (aerobic capacity and substrate usage) and perceived exertion outcomes. Point of application #1: Aerobic capacity (maximal consumption of oxygen) and the usage of fat as a fuel to support energy production during exercise were similar between runs. Point of application #2: Maximal perceived exertion (Borg’s 6-20) was similar during early-morning and late-night runs. Point of application #3: While research indicates that people may prefer activity in the morning or evening, and this might impact metabolic responses to the exercise bout, most of our participants (n=8) identified with no preference for exercising in the early-morning or late-night.
