Noise Pollution? What\u27s the solution?: Understanding Traffic Noise Pollution in Gettysburg, Pennsylvania

Noise pollution can be damaging to a community by impacting its atmosphere as well as the health of its residents, local quality of life, and local economy. Our study sought to gain insight into the level of noise pollution in Gettysburg, both in-town and on the Gettysburg College campus, and how noise pollution may be affecting the local residents and students. We selected 9 sampling sites, 6 in-town and 3 on the college campus, and measured the noise pollution in dBA with portable sound meters three days a week and three times a day over a three week period. Our data showed no major trends in terms of time of day or day of the week, but there were clear differences in noise pollution levels between the different sites in that town sites were generally louder than on campus sites. Noise pollution in town was often louder than 70 dBA, the noise threshold that indicates possible hearing damage overtime set by the World Health Organization. Gettysburg has recently enacted a noise ordinance; our study suggests the Borough possibly could do more to mitigate traffic noise by repairing roads and manipulating road design

Using Web Technology to Teach Students about Their Digital World

In the School of Business at The College of New Jersey, students are required to take two courses in Management Information Technology (MIT). All students enroll in the same first course. This course focuses on Emerging Technologies and intermediate level data analysis skills. Students are then free to choose their second course. Each MIT course requires that we spend time discussing the social, ethical, and legal issues surrounding technology. This is often a difficult lecture because students think that we are preaching rather than educating them. We also face an expanding curriculum due to the explosion in technology but our core curriculum remains limited to these two classes. To help us overcome our challenges, we turned to Web 2.0 technology to create an interactive learning platform where faculty and students could write and comment about emerging social issues surrounding the Web. In the learning environment that we created, students were provided the opportunity to work with many Web 2.0 tools to learn, interact with fellow students, and express their opinions and ideas. Our team employed the open source content management system Wordpress to build, manage, and monitor this site. In addition, we used Google Analytics to gather usage information. This paper will discuss the process we took to build and use the site and some of the lessons we learned along the way

Variations in pre-analytical FFPE sample processing and bioinformatics: challenges for next generation molecular diagnostic testing in clinical pathology

Advances in cellular pathology techniques will improve diagnostic medicine. However, such improvements have to overcome many challenges including variations in pre-analytical sample processing, bioinformatics data analysis and clinical interpretation of data. In order to resolve such challenges, bioinformatics needs to become more tightly coupled to the experimental methodology development

A novel NGS library preparation method to characterize native termini of fragmented DNA.

Biological and chemical DNA fragmentation generates DNA molecules with a variety of termini, including blunt ends and single-stranded overhangs. We have developed a Next Generation Sequencing (NGS) assay, XACTLY, to interrogate the termini of fragmented DNA, information traditionally lost in standard NGS library preparation methods. Here we describe the XACTLY method, showcase its sensitivity and specificity, and demonstrate its utility in in vitro experiments. The XACTLY assay is able to report relative abundances of all lengths and types (5' and 3') of single-stranded overhangs, if present, on each DNA fragment with an overall accuracy between 80-90%. In addition, XACTLY retains the sequence of each native DNA molecule after fragmentation and can capture the genomic landscape of cleavage events at single nucleotide resolution. The XACTLY assay can be applied as a novel research and discovery tool for fragmentation analyses and in cell-free DNA
