Distinctions in practice within coaching in Scotland
This research sought to identify distinctions in the practice of coaches within
Scotland. A survey design was adopted, with a snowball sampling strategy
generating 74 responses. The data from coaches within Scotland, compared with
that from respondents in other European nations, suggest that: a greater proportion
of the Scottish coaching community are male, that coaches commonly evaluate at
the end of every meeting and also seek feedback from commissioning managers as
well as clients, that there are numerous approaches to coaching and also to
continuous professional development that are less widely adopted in Scotland, that
the reputation of the coaching provider is often an important factor for those
commissioning coaching and that there are preferences for certain coaching models
when presented with particular client issues. Recommendations are made for future
analytical research to identify causal factors for any phenomena that can be
cautiously determined from this data set

Distinctions in practice within coaching in Wales
This research sought to identify distinctions in the practice of coaches within Wales,
compared to other European nations. A survey design was adopted, with a snowball
sampling strategy generating 150 respondents. Seven surveyed aspects of coaching
practice produced distinctive responses from coaches within Wales: they are less
likely to have membership of any professional coaching bodies, they spend a very
small proportion of their working time coaching, they are more likely to operate as
internal coaches or for low fees, they are more likely to engage in self-reflection and
participate in peer networks, they have a marked preference for behavioural/goalfocused methods, they are thorough in the range of topics they cover when
contracting and they are likely to be selected as coaches based predominantly upon
their experience levels. Recommendations are made for future analytical research to
identify causal factors for these distinctions
Evaporite karst geohazards in the Delaware Basin, Texas: review of traditional karst studies coupled with geophysical and remote sensing characterization
Evaporite karst throughout the Gypsum Plain of west Texas is complex and extensive, including manifestations ranging from intrastratal brecciation and hypogene caves to epigene features and suffosion caves. Recent advances in hydrocarbon exploration and extraction has resulted in increased infrastructure development and utilization in the area; as a result, delineation and characterization of potential karst geohazards throughout the region have become a greater concern. While traditional karst surveys are essential for delineating the subsurface extent and morphology of individual caves for speleogenetic interpretation, these methods tend to underestimate the total extent of karst development and require surficial manifestation of karst phenomena. Therefore, this study utilizes a composite suite of remote sensing and traditional field studies for improved karst delineation and detection of potential karst geohazards within gypsum karst. Color InfraRed (CIR) imagery were utilized for delineation of lineaments associated with fractures, while Normalized Density Vegetation Index (NDVI) analyses were used to delineate regions of increased moisture flux and probable zones of shallow karst development. Digital Elevation Models (DEM) constructed from high-resolution LiDAR (Light Detection and Ranging) data were used to spatially interpret sinkholes, while analyses of LiDAR intensity data were used in a novel way to categorize local variations in surface geology. Resistivity data, including both direct current (DC) and capacitively coupled (CC) resistivity analyses, were acquired and interpreted throughout the study area to delineate potential shallow karst geohazards specifically associated with roadways of geohazard concern; however, detailed knowledge of the surrounding geology and local karst development proved essential for proper interpretation of resistivity inversions. The composite suite of traditional field investigations and remotely sensed karst delineations used in this study illustrate how complex gypsum karst terrains can be characterized with greater detail through the utilization of rapidly advancing technologies, especially in arid environments with low vegetation densities
End of Life Disposal for Three Libration Point Missions through Manipulation of the Jacobi Constant and Zero Velocity Curves
The aim of this investigation is to determine the feasibility of mission disposal by inserting the spacecraft into a heliocentric orbit along the unstable manifold and then manipulating the Jacobi constant to prevent the spacecraft from returning to the Earth-Moon system. This investigation focuses around L1 orbits representative of ACE, WIND, and SOHO. It will model the impulsive delta-V necessary to close the zero velocity curves after escape through the L1 gateway in the circular restricted three body model and also include full ephemeris force models and higher fidelity finite maneuver models for the three spacecraft
Applying Dynamical Systems Theory to Optimize Libration Point Orbit Stationkeeping Maneuvers for WIND
NASA's WIND mission has been operating in a large amplitude Lissajous orbit in the vicinity of the interior libration point of the Sun-Earth/Moon system since 2004. Regular stationkeeping maneuvers are required to maintain the orbit due to the instability around the collinear libration points. Historically these stationkeeping maneuvers have been performed by applying an incremental change in velocity, or (delta)v along the spacecraft-Sun vector as projected into the ecliptic plane. Previous studies have shown that the magnitude of libration point stationkeeping maneuvers can be minimized by applying the (delta)v in the direction of the local stable manifold found using dynamical systems theory. This paper presents the analysis of this new maneuver strategy which shows that the magnitude of stationkeeping maneuvers can be decreased by 5 to 25 percent, depending on the location in the orbit where the maneuver is performed. The implementation of the optimized maneuver method into operations is discussed and results are presented for the first two optimized stationkeeping maneuvers executed by WIND
The Value Added of Honors Programs in Recruitment, Retention, and Student Success: Impacts of the Honors College at the University of Mississippi
In a recent essay, M. Roy Wilson (2015), President of Wayne State University, and Jerry Herron, Dean of the Honors College, discuss the value added of honors programs in terms that should be familiar to numerous constituencies associated with honors education. Wilson and Herron write about honors education largely in terms of the experiences it provides students:
the [honors] college is not tied to any particular academic discipline; instead, it represents the virtues of a liberal education that reaches across departments, schools, and colleges. For our students, the aim is to integrate the specialized—and essential—knowledge of the disciplines into a broader understanding of themselves, our community, and the world. With understanding comes engagement. The honors experience at Wayne State is based on four pillars—community, service, research, career— which define the curricular and co-curricular elements of our program and also highlight the distinctive strengths of this university, at the same time making real the value added, high-impact practices that define the very best of undergraduate education.

Altered synaptic plasticity in the mossy fibre pathway of transgenic mice expressing mutant amyloid precursor protein
Aβ peptides derived from the cleavage of amyloid precursor protein are widely believed to play an important role in the pathophysiology of Alzheimer's disease. A common way to study the impact of these molecules on CNS function is to compare the physiology of transgenic mice that overproduce Aβ with non-transgenic animals. In the hippocampus, this approach has been frequently applied to the investigation of synaptic transmission and plasticity in the perforant and Schaffer collateral commissural pathways, the first and third components of the classical hippocampal trisynaptic circuit, respectively. Similar studies however have not been carried out on the remaining component of the trisynaptic circuit, the mossy fibre pathway. Using transverse hippocampal slices prepared from ~2 year old animals we have compared mossy fibre synaptic function in wild-type mice and their Tg2576 littermates which age-dependently overproduce Aβ. Input-output curves were not altered in slices from Tg2576 mice, but these animals exhibited a significant loss of the prominent frequency-facilitation expressed by the mossy fibre pathway. In addition to this change in short term synaptic plasticity, high frequency stimulation-induced, NMDA-receptor-independent LTP was absent in slices from the transgenic mice. These data represent the first description of functional deficits in the mossy fibre pathway of Aβ-overproducing transgenic mice
MEME-LaB : motif analysis in clusters
Genome-wide expression analysis can result in large numbers of clusters of co-expressed genes. While there are tools for ab initio discovery of transcription factor binding sites, most do not provide a quick and easy way to study large numbers of clusters. To address this, we introduce a web-tool called MEME-LaB. The tool wraps MEME (an ab initio motif finder), providing an interface for users to input multiple gene clusters, retrieve promoter sequences, run motif finding, and then easily browse and condense the results, facilitating better interpretation of the results from large-scale datasets
