Developing an Information Literacy-Intensive Forensic Science Course

American Academy of Forensic Sciences 2018 Poster PresentationThe goal of this presentation is to demonstrate a model where forensic science educators can utilize resources at university libraries to promote scientific information literacy and lifelong learning strategies for their forensic science students that they can continue to use in their professional forensic careers. This presentation will impact the forensic science community by highlighting the benefits of forensic science faculty collaborating with subject specialist academic librarians to produce a course filling a gap in the education of future forensic science practitioners. This course facilitates the development of productive search strategies and how different types of scientific research and legal materials are relevant to various forensic science disciplines. This collaboration has demonstrated a need for promoting information literacy, specifically for open-access materials, on forensic science information to these students so that once they graduate they still can acquire the valuable information necessary for their job. As a result of this research, the researchers saw a need to expand this information literacy beyond the classroom and acquired National Institute of Justice (NIJ) funding to allow for the development of these materials as modules to be used by practitioners in crime laboratories to enhance available resources for their use. Forensic science is a multi-faceted field including expertise from a variety of disciplines. A challenge for creating a college course to address skills to develop information literacy competencies and encourage lifelong learning for future practitioners is covering those diverse disciplines. This presentation will detail how librarians at Texas A&M University developed a junior-level forensic science seminar in collaboration with a forensic science faculty member to meet the research needs of students in the forensic sciences program. The learning outcomes of this class include teaching students to describe problem-solving principles, organize typical operational protocols, recognize the scientific basis and application of tools and techniques in forensic science, compare capabilities and limitations, and to summarize and illustrate current scientific, ethical, and legal issues. The presenters will detail the steps taken to create six separate information literacy-intensive classes, including the development of the assignments, and how feedback was provided to the students. These classes included sessions on dissecting scholarly articles and case law, as well as classroom discussions to teach students how to use the structure of research articles and case law to easily evaluate information. By creating this information literacy course, instructors were able to better prepare students for their program’s research intensive courses with the amount of detail required that cannot be covered in a traditional one hour library instruction session. Such skills will be of value when working in forensic science fields and the need arrives for locating similar resources in relation to casework. Additionally, the presentation will address issues raised in class, such as open access, database access, and evaluation of science and legal materials, which helps the students translate current school work to their future careers. To further this concept of information literacy, as previously mentioned, the researchers received NIJ funding to determine how forensic scientist locate and evaluate information and to create educational materials aimed at enhancing these skills and increase awareness of other valuable informational resources. Locating and evaluating high-quality forensic science literature will help forensic scientists engage in quality science practices. Results from this class, which is now in its third year of evaluation, show that students who take this preparatory course are better prepared for conducting meaningful research for their writing-intensive senior-level classes both in their abilities to find relevant materials and how to utilize and cite these materials. Graduating students who go on to graduate or law school have also reported back that taking this course gave them a foundation for which to build on in their advanced studies.Grant funding provided by the National Institute of Justice, Office of Justice Programs, the United States Department of Justice through 2016-R2-CX-0054.

Black soldier fly (Diptera: Stratiomyidae) larval heat generation and management

: Mass production of black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), larvae results in massive heat generation, which impacts facility management, waste conversion, and larval production. We tested daily substrate temperatures with different population densities (i.e., 0, 500, 1000, 5000, and 10 000 larvae/pan), different population sizes (i.e., 166, 1000, and 10 000 larvae at a fixed feed ratio) and air temperatures (i.e., 20 and 30 °C) on various production parameters. Impacts of shifting larvae from 30 to 20 °C on either day 9 or 11 were also determined. Larval activity increased substrate temperatures significantly (i.e., at least 10 °C above air temperatures). Low air temperature favored growth with the higher population sizes while high temperature favored growth with low population sizes. The greatest average individual larval weights (e.g., 0.126 and 0.124 g) and feed conversion ratios (e.g., 1.92 and 2.08 g/g) were recorded for either 10 000 larvae reared at 20 °C or 100 larvae reared at 30 °C. Shifting temperatures from high (30 °C) to low (20 °C) in between (∼10-d-old larvae) impacted larval production weights (16% increases) and feed conversion ratios (increased 14%). Facilities should consider the impact of larval density, population size, and air temperature during black soldier fly mass production as these factors impact overall larval production

Composicao das especies de moscas-varejeiras do lixo no norte da Tailandia: avaliacao da altitude

Distribution and occurrence of blow flies of forensic importance was performed during 2007 and 2008 in Chiang Mai and Lampang Provinces, northern Thailand.

A metagenomic assessment of the bacteria associated with Lucilia sericata and Lucilia cuprina (Diptera: Calliphoridae)

Lucilia Robineau-Desvoidy (Diptera: Calliphoridae) is a blow fly genus of forensic, medical, veterinary, and agricultural importance. This genus is also famous because of its beneficial uses in maggot debridement therapy (MDT). Although the genus is of considerable economic importance, our knowledge about microbes associated with these flies and how these bacteria are horizontally and trans-generationally transmitted is limited. In this study, we characterized bacteria associated with different life stages of Lucilia sericata (Meigen) and Lucilia cuprina(Wiedemann) and in the salivary gland of L. sericata by using 16S rDNA 454 pyrosequencing. Bacteria associated with the salivary gland of L. sericata were also characterized using light and transmission electron microscopy (TEM). Results from this study suggest that the majority of bacteria associated with these flies belong to phyla Proteobacteria, Firmicutes, andBacteroidetes, and most bacteria are maintained intragenerationally, with a considerable degree of turnover from generation to generation. In both species, second-generation eggs exhibited the highest bacterial phylum diversity (20 % genetic distance) than other life stages. The Lucilia sister species shared the majority of their classified genera. Of the shared bacterial genera, Providencia, Ignatzschineria, Lactobacillus, Lactococcus, Vagococcus, Morganella, and Myroides were present at relatively high abundances. Lactobacillus, Proteus,Diaphorobacter, and Morganella were the dominant bacterial genera associated with a survey of the salivary gland of L. sericata. TEM analysis showed a sparse distribution of both Gram-positive and Gram-negative bacteria in the salivary gland of L. sericata. There was more evidence for horizontal transmission of bacteria than there was for trans-generational inheritance. Several pathogenic genera were either amplified or reduced by the larval feeding on decomposing liver as a resource. Overall, this study provides information on bacterial communities associated with different life stages of Lucilia and their horizontal and trans-generational transmission, which may help in the development of better vector-borne disease management and MDT methods
