Understanding and acceptance of AAC are lacking in our communities. IPFW has implemented two programs to increase the awareness of AAC in the Fort Wayne community, in hopes of fostering an attitude of acceptance. AAC World and IPFW AAC Poss-Abilities Theatre Camp are unique programs designed to educate the public, as well as provide hands-on experiences for students enrolled in the Communication Sciences u26 Disorders program at IPFW

OBSERVATION OF THE SEDIMENT GRAIN SIZE DISTRIBUTION CHANGE ALONG A CREEK PROFILE IN INDIANA, USA JOHNSTON, Shelby, Geosciences, Indiana University-Purdue University Ft. Wayne (IPFW), Fort Wayne, IN 46805 and ISIORHO, K. Solomon, Geosciences, Indiana University - Purdue University Fort Wayne (IPFW), Fort Wayne, IN 46805-1499, johnsk01@students.ipfw.edu As water moves downstream, it carries sediments that become sorted and rounded. The purpose of this research project, which is a requirement for an upper level geology course, is to determine the water content of soil, overall composition of the sediment (gravel, sand, etc.), and grain size changes (if it does change) along a river profile, using a creek that runs through the Indiana University-Purdue University Fort Wayne (IPFW) campus. In the 2014 Fall semester, grain size distribution analysis was performed on fourteen soil samples collected along the length of the creek. Fourteen soil samples were also collected from same sites in the 2015 Spring semester. The data indicates that water content and grain size distribution vary along the creek profile. Certain samples had significantly lower water content than others, that, when examined more closely, revealed a different soil profile containing less silt-clays and higher sand-gravel components. The average water content for all samples in the Fall of 2014 is 21.87% with minimal variation; this is closely mimicked in the Spring 2015 samples with average water content of 25.74% again with minimal variation. Although the samples were taken from the same locations, there are differences in soil composition. The soils range from coarse to fine grained sand, but are generally fine-grained. Knowing the cause(s) of the finning of the sediments downstream in the creek may help in managing the stream and probably other rivers in northern Indiana. This is an ongoing research and new data will be presented

Limestone and shale facies of the Upper Ordovician Grant Lake Formation (Katian: Cincinnatian, Maysvillian) are well exposed in the Cincinnati Arch region of southern Ohio and north-central Kentucky, USA. These rocks record a gradual change in lithofacies and biofacies along a gently northward-sloping ramp. This gradient spans very shallow, olive-gray, platy, laminated dolostones with sparse ostracodes in the south to offshore, nodular, phosphatic, brachiopod-rich limestones and marls in the north. This study uses facies analysis in outcrop to determine paleoenvironmental parameters, particularly those related to water depth (e.g., position of the photic zone and shoreline, relative degree of environmental energy). Within a tightly correlated stratigraphic interval (the Mount Auburn and Straight Creek members of the Grant Lake Formation and the Terrill Member of the Ashlock Formation), we document the occurrence of paleoenvironmental indicators, including desiccation cracks and light-depth indicators, such as red and green algal fossils and oncolites. This permitted recognition of a ramp with an average gradient of 10.20 cm water depth per horizontal kilometer. Thus, shallow subtidal (.lagoonal.) deposits in the upramp portion fall within the 1.5.6 m depth range, cross-bedded grainstones representing shoal-type environments fall within the 6.18 m depth range and subtidal, shell-rich deposits in the downramp portion fall within the 20.30 m depth range. These estimates match interpretations of depth independently derived from faunal and sedimentologic evidence that previously suggested a gentle ramp gradient and contribute to ongoing and future high-resolution paleontologic and stratigraphic studies of the Cincinnati Arch region

Carmen Hamilton is an IPFW junior pursuing a B.A. in History, and certificates in psychological research and international studies. With no prior interest in comic book heroes, Carmen’s research for this paper began as an effort to test the validity of an Episode of Comedy Central’s Drunk History, “Drunk History Atlanta: Stetson Kennedy Infiltrates the KKK.

Frank Quinn of Jaffe-Quinn fame (see [1]) worked out the basics of his own account of how mathematical practice should be described and analyzed, partly by historical comparisons with 19th century mathematics, partly by an analysis of contemporary mathematics and its pedagogy ([2]). Despite his claim that for this task, u22professional philosophers seem as irrelevant as Aristotle is to modern physics,u22 this philosophy talk will provide a critical summary of his main observations and arguments (unpublished except for [3]). The goal is to inject some of Quinns remarks to the current conversation on mathematical practice.

Among reptiles, reproduction in the absence of males is often assumed to result from long-term sperm storage. Through the application of molecular genetic tools, biologists are beginning to recognize that facultative parthenogenesis can also explain such reproductive events in snakes. We observed a Copperhead (Agkistrodon contortrix) give birth to a stillborn neonate and four infertile ova after 9 yr in isolation from male snakes. To test the hypothesis that the neonate was produced asexually, we screened a panel of 10 microsatellite loci to genotype the mother and her offspring, as well as wild-caught individuals in the motheru27s population of origin, to assess the probability of paternity. Confirming prior research on Copperheads that suggests parthenogenesis by terminal fusion automixis, we found that four heterozygous maternal loci were homozygous in the neonate. We calculated the probability of a random male from the population as a sire to the neonate to be 2.32 × 10−13 by using the population allele frequencies and the genotype of the neonate. These results further confirm that Copperheads are facultatively parthenogenetic and suggest that this reproductive mode may be general within the species

Varying degrees of nervousness may be found in patients presenting for gynecologic examination. It is the clinicianu27s role to distinguish typical (expected) anxiety from that which is considered excessive. Extreme stress reactions may occur from a variety of reasons including prior sexual assault, post-traumatic stress disorder, and/or intimate partner violence. Approach to care delivery is critical for establishing a trusting relationship. Case study format will be used to discuss stress-reducing techniques during annual examinations

In this work, we briefly report some attempts to control regioisomeric bisadditions on Sc3N@Ih-C80 and Lu3N@Ih-C80 using the tether-controlled multifunctionalization method. We then describe the use of independent (nontethered) bis-1,3-dipolar cycloaddition reactions and the characterization of 5 new bisadducts, 3 for Sc3N@C80 and 2 for Lu3N@C80, which have never been reported before. Unexpectedly and remarkably, 4 of these compounds exhibit relatively high symmetry and 2 of these bisadducts are the first examples of intrinsically chiral endohedral compounds, due to the addition pattern, not to the presence of chiral centers on the addends. Since an analysis of the statistically possible number of bisadduct isomers on an Ih-C80 cage has not been reported, we present it here

The present study describes the development of a multi-linear regression model to predict the effect of building shape on total energy consumption in two different climate regions (i.e. cold-dry and warm-marine). Seven building shapes including H-shape, T-shape, rectangle, etc. were considered in this study. The simplified model can be used to conduct a parametric study in order to investigate the effect of building parameters on total heating and cooling load. Building simulation software programs, including eQUEST and DOE-2 were used to build and simulate individual building configuration that were generated using Monte Carlo simulation techniques. Ten thousand simulations for seven building shapes were performed to create a comprehensive dataset covering the full ranges of design parameters. Statistical analysis was performed using R statistical analysis program to develop a set of linear regression equations predicting energy consumption of each design scenario. In addition, the influence of several design parameters on building energy consumption was further investigated using the sensitivity analysis procedure. The difference between regression-predicted and DOE-2 simulated annual building energy consumption were largely within 5%. It is envisioned that the developed regression models can be used to estimate the total energy consumption in the early stages of the design when different building schemes and design concepts are being considered

In this paper a methodology to identify gaps in course learning outcomes using Fundamentals of Engineering (FE) exam administered by the National Council of Examiners for Engineering and Surveying (NCEES) is presented. The methodology is applied to selected courses in General Engineering, Mechanical Engineering (international university), and Civil Engineering (US University). It has been concluded that the methodology succeeded to identify gaps in course learning outcomes of these courses and corrective actions to topics covered is consequently proposed. The proposed methodology is adequate for programs already developed and is recommended as a continuous improvement and review method for engineering curriculum

The widespread availability of mobile devices has made information available to many on the go, making it a valuable tool in everyday life. Their ability to look up information on the fly and assist with a useru27s information retrieval in a timely fashion make them a natural everyday carry. However, a limitation of these devices is the lack of screen space available to display information, thus presenting a potential problem to this seemingly ideal device. A technique to present a large amount of information, cohesively, is required to make users’ search activities more convenient and effective. We present visualization techniques designed for presenting lengthy text-based documents on mobile devices. The system uses two different visualizations, Overview and Detail. The Overview shows the overall profile of search terms in the document(s). The Detail View presents the requested information, clearly displaying to the user what content is available. By utilizing this two step approach, we can assist usersu27 search activities by making them more effective in their search concerning lengthy text contents. A pilot experiment was conducted to evaluate the effectiveness of these visual interfaces compared to a traditional text-based interface. For a majority of measured items, the testers showed a higher degree of satisfaction using the visualization, that was developed to address the difficulties in exploring text content on a small screen device. Although a larger scale usability test is expected in the near future, our initial study shows the feasibility of using multi-level visual interfaces as a search-supporting tool to review lengthy text documents on mobile devices

This article reexamines the treatment of gender and feminism in technical, business, and workplace writing studies—areas in which the three of us teach. Surprisingly, the published discourse of our field seems to implicitly minimize the gendered nature of business and technical writing workplaces and classrooms. To understand this apparent lack of focus, we review five technical and business communication academic journals and build on previous quantitative evaluations done by Isabelle Thompson in 1999 and by Isabelle Thompson Elizabeth Overman Smith in 2006. We also review nine popular textbooks using a content analysis method based on Thompson’s work. Finally, we discuss current research in feminist pedagogies vis-à-vis these results and our own experiences in the professional writing classroom

Gawande’s fourth popular book, Being Mortal, layers touching story after touching story into a devastating critique of how people approach the end of life. At times, keeping all the narratives straight proves difficult, yet each piece of each narrative remains powerful. These accounts are woven neatly together with personal and professional reflection as well as scholarship. For example, in the midst of telling readers about his grandmother-in-lawu27s approach to the end of life, surgeon/journalist Gawande (Brigham and Womenu27s Hospital; Harvard Medical School; The New Yorker) quotes B. Vladeck, summing up the origins of one problematic approach: “describing the history of nursing homes from the perspective of the elderly ‘is like describing the opening of the American West from the perspective of the mules’” (Unloving Care: The Nursing Home Tragedy, 1980). As Being Mortal draws to a close, Gawande offers some (albeit tentative) recommendations for improving how people face the end of life. Though he does not break new ground here, he rightly points out and announces human shortcomings in a way that all can see and understand. Summing Up: Highly recommended. All levels/libraries

Nucleobase biochemistry plays a central role in serving various needs of plants during their growth and development.The synthesis of nucleic acids, carbohydrate metabolism, and overall plant growth, development, and reproduction depends on a continuous flow of purines and pyrimidines attributed to a balance of different pathways like de novo synthesis, salvage pathways, and catabolic pathways.This intricate nucleobase biochemistry requires intra- and inter-cellular movement of nucleobases facilitated by different families of membrane transporter proteins.The genome of Zea mays contains three genes that encode for putative azagunainelike transporters (AZG) with high similarity to a previously characterized AZG transporter of Arabidopsis thaliana in our lab.The goal of this research is to identify the substrate specificity and binding properties of the three putative members of AZG-like family of Zea mays; ZmAZG1, ZmAZG2 and ZmAZG3.The genes encoding for ZmAZG1, ZmAZG2, and ZmAZG3 were independently PCR-cloned then spliced into a yeast expression vector, and the recombinant plasmids transformed into yeast cells lacking their native nucleobase transporters.The transgenic yeast cells were assayed for their ability to uptake a panel of radiolabeled nucleobases to reveal the transport profiles of the heterologously expressed ZmAZG transporters.The results show that ZmAZG1 facilitates transport of uracil whereas, ZmAZG3 transports adenine, guanine, cytosine and hypoxanthine.The kinetic properties of AZG-like transporters were further revealed using heterologous competition between radiolabeled [3H]- hypoxanthine as a substrate and an array of non-radioactive cold nucleobase competitors.For ZmAZG3, the nucleobase adenine competitively inhibited [3H]-hypoxanthine transport, whereas cytosine and xanthine were respectively found to be weak and poor competitive inhibitors.As for ZmAZG2, the nucleobases adenine and cytosine competitively inhibited [3H]-hypoxanthine transport, while xanthine and uric acid were respectively found to be weak and poor inhibitors.Moreover, both ZmAZG2 and ZmAZG3 continually transported [3H]-hypoxanthine over a period of two hours without reaching a saturation point suggesting their pivotal role in hypoxanthine transport.These findings shed light on the significant role the AZG-like transporters play in maize growth and development.http://opus.ipfw.edu/stu_symp2015/1008/thumbnail.jp

In this presentation we consider the best uniform approximation of the u22checkmark functionu22 |x-a| by polynomials on the interval [-1,1]. The dynamic behavior of the points of alternation in terms of the parameter a is investigated. For certain values of this parameter the approximation gives rise to the classical polynomials of Chebyshev and Zolotarev. We include numerical computations to illustrate the results

This trip will cover the high-resolution sequence stratigraphy, depositional environment, process sedimentology, and paleontology of four spectacularly fossil-rich exposures of the Cincinnati Upper Ordovician (internationally the Katian Stage; in North America the Cincinnatian Series) in southeastern Indiana. Stops include Madison (Richmondian through Silurian), Lawrenceburg (Edenian and Maysvillian), Southgate Hill (Deeper water Richmondian), and Brookville Dam (Maysvillian) . The Cincinnatian is characterized by alternating beds of shell-rich limestones (shell beds) and fossil poor, mudstones. Limestone-rich and mud-rich intervals define meter scale and 10-meter-scale cycles. The sedimentological processes that generated these beds and cycles are the subject of recent research. We will discuss the role of high energy events and fluctuating sediment supply in generating these strata, and discuss the possibility of correlating meter-scale cycles across facies transitions over tens of kilometers of distance using physical, paleontological, and geochemical techniques. We will also discuss how sedimentological processes lead to the destruction of organic matter in a succession of obviously fossil-rich strata. There will be ample opportunity to collect a spectacularly fossil-rich slab, and perhaps even a perfect trilobite! The trip will depart from the Crowne Plaza Indianapolis at 8:00 AM and return at 6:30 PM. Antendees are urged to be flexible in scheduling Saturday evening activities

While several nonchromatographic methods are available for the isolation and purification of endohedral fullerenes of the type M3N@Ih-C80, little work has been done that would allow other members of the M3N@C2n family to be isolated with minimal chromatography. Here, we report that Gd3N@D2(35)-C88 can be isolated from the multitude of endohedral and empty cage fullerenes present in carbon soot obtained by electric-arc synthesis using Gd2O3-doped graphite rods. The procedure developed utilizes successive precipitation with the Lewis acids CaCl2 and ZnCl2 followed by treatment with amino-functionalized silica gel. The structure of the product was identified by single-crystal X-ray diffraction
