The Role of Lipid Mediator Prostaglandin E2 in Early Neuronal Development

Lipid mediator prostaglandin E2 (PGE2) plays a pivotal role in early development of the nervous system. Abnormal PGE2 signaling in neurodevelopment has also been implicated in autism. Increased levels of PGE2 have been attributed to maternal infection and the inflammatory response. My in vitro work shows that elevated levels of PGE2 cause an increase in cytosolic and growth cone calcium levels in differentiated neuroectodermal (NE-4C) cells and a dose- and time-dependent effect on neurite extension length. Furthermore, PGE2 induced subcellular localization of the EP4 receptor to the plasma membrane in NE-4C stem cells and growth cones of differentiated NE-4C cells. My in vivo work shows that prenatal exposure to PGE2 results in differential mRNA levels of two important developmental genes Wnt3a and Fosl1 in the mouse brain at various embryonic stages. This furthers our understanding of the functional implications of abnormal PGE2 signaling in the neurodevelopment of autism

Usage of Specialized Fence-Gaps in a Black Rhinoceros Conservancy in Kenya

Fencing is increasingly used in wildlife conservation. Keeping wildlife segregated from local communities, while permitting wildlife access to the greater landscape matrix is a complex task. We investigated the effectiveness of specially designed fence-gaps on animal movement at a Kenyan rhinoceros conservancy, using camera-traps over a four-year period. The fence-gap design restricted the movement of black (Diceris bicornis) and white rhinoceroses (Ceratotherium simum simum) but permitted the movement of other species. We documented over 6000 crossing events of over 50 000 individuals which used the fence-gaps to enter or leave the conservancy. We recorded 37 mammal species and two species of bird using the fence-gaps. We conclude that this fence-gap design is effective at restricting rhinoceros movement and at permitting other wildlife movement into and out of the conservancy. We recommend that fenced-in rhinoceros conservancies that desire enhanced connectivity consider this fence-gap design to help re-connect their reserves to the outside landscape matrix while continuing to provide enhanced protection for their rhinoceroses

Look for Problems and Find Opportunities: Lean in Your Library

Lean organizations actively seek out waste (time, energy and resources) and inefficiencies in order to maximize value for customers. Every problem acknowledged is an opportunity to improve something for your patrons. Several years ago, South Dakota State University began implementing Lean across campus. Staff at Briggs Library are using Lean principles to improve library processes, both large and small. As part of the library’s strategic plan, every department is responsible for at least two Lean projects per year. The examples presented here illustrate the value of Lean for customers as well as the benefits to the organization.https://openprairie.sdstate.edu/library_presentations/1001/thumbnail.jp

Action and familiarity effects on self and other expert musicians’ Laban effort-shape analyses of expressive bodily behaviors in instrumental music performance: a case study approach

Self-reflective performance review and expert evaluation are features of Western music performance practice. While music is usually the focus, visual information provided by performing musicians’ expressive bodily behaviors communicates expressiveness to musically trained and untrained observers. Yet, within a seemingly homogenous group, such as one of musically trained individuals, diversity of experience exists. Individual differences potentially affect perception of the subtleties of expressive performance, and performers’ effective communication of their expressive intentions. This study aimed to compare self- and other expert musicians’ perception of expressive bodily behaviors observed in marimba performance. We hypothesized that analyses of expressive bodily behaviors differ between expert musicians according to their specialist motor expertise and familiarity with the music. Two professional percussionists and experienced marimba players, and one professional classical singer took part in the study. Participants independently conducted Laban effort-shape analysis – proposing that intentions manifest in bodily activity are understood through shared embodied processes – of a marimbists’ expressive bodily behaviors in an audio-visual performance recording. For one percussionist, this was a self-reflective analysis. The work was unfamiliar to the other percussionist and singer. Perception of the performer’s expressive bodily behaviors appeared to differ according to participants’ individual instrumental or vocal motor expertise, and familiarity with the music. Furthermore, individual type of motor experience appeared to direct participants’ attention in approaching the analyses. Findings support forward and inverse perception–action models, and embodied cognitive theory. Implications offer scientific rigor and artistic interest for how performance practitioners can reflectively analyze performance to improve expressive communication

The Parton Structure of the Nucleon and Precision Determination of the Weinberg Angle in Neutrino Scattering

A recently completed next-to-leading-order program to calculate neutrino cross sections, including power-suppressed mass correction terms, has been applied to evaluate the Paschos-Wolfenstein relation, in order to quantitatively assess the validity and significance of the NuTeV anomaly. In particular, we study the shift of $\sin^2 \theta_{\mathrm{W}}$ obtained in calculations with a new generation of PDF sets that allow $s(x)\neq \bar{s}(x)$, enabled by recent neutrino dimuon data from CCFR and NuTeV, as compared to the previous $s = \bar{s}$ parton distribution functions like CTEQ6M. The extracted value of $\sin^2 \theta_{\mathrm{W}}$ is closely correlated with the strangeness asymmetry momentum integral $\int_{0}^{1}x[s(x)-\bar{s}(x)] dx$. We also consider isospin violating effects that have recently been explored by the MRST group. The results of our study suggest that the new dimuon data, the Weinberg angle measurement, and other data sets used in global QCD parton structure analysis can all be consistent within the Standard Model.Comment: 4 page

TNT07 MIO San Francisco Bay, atmospheric effects after action report

The authors participated in four Tactical Network Topology Marine Interdiction Operations (TNT MIOs) during FY 2007. The overall goals of the authors TNT MIO studies were (1) to provide military and law enforcement personnel with real time and future information on how the environment will affect marine interdiction operations and (2) to develop, verify and improve models and procedures used in (1) by comparing predictions with actual in situ observations. Similar to earlier TNT MIO experiments, the authors addressed how environmental factors affect the transmission of radiation in the visible and radio bands of the electromagnetic spectrum. But, unlike the earlier experiments, more emphasis was placed on other environmental effects such as winds, sea state, tides and other weather factors. By developing a system to provide the relevant personnel with this information we hope to (1) enhance overall situational awareness, (2) enhance mission planning and safety and (3) provide an advantage over any potential adversaries who might not consider these atmospheric effects. For this project we made in situ measurements of atmospheric conditions as and also incorporated a large amount of outside information to give a better picture of the environmental conditions that affected the MIO. In addition to providing weather briefings in the mornings of the operations, several environmental products were made available via the experimental networks. These products included results of visibility and radar range model predictions developed especially for these experiments as well as more general products downloaded from the World Wide Web. The data collection efforts were successful and allowed verification and improvement of the effects models.Approved for public release; distribution is unlimited
