Panama disease caused by Fusarium oxysporum f. sp. cubense infection on banana is devastating banana plantations worldwide. Biological control has been proposed to suppress Panama disease, though the stability and survival of bio-control microorganisms in field setting is largely unknown. In order to develop a bio-control strategy for this disease, 16S rRNA gene sequencing was used to assess the microbial community of a disease-suppressive soil. Bacillus was identified as the dominant bacterial group in the suppressive soil. For this reason, B. amyloliquefaciens NJN-6 isolated from the suppressive soil was selected as a potential bio-control agent. A bioorganic fertilizer (BIO), formulated by combining this isolate with compost, was applied in nursery pots to assess the bio-control of Panama disease. Results showed that BIO significantly decreased disease incidence by 68.5%, resulting in a doubled yield. Moreover, bacterial community structure was significantly correlated to disease incidence and yield and Bacillus colonization was negatively correlated with pathogen abundance and disease incidence, but positively correlated to yield. In total, the application of BIO altered the rhizo-bacterial community by establishing beneficial strains that dominated the microbial community and decreased pathogen colonization in the banana rhizosphere, which plays an important role in the management of Panama disease.

Critical flicker fusion thresholds (CFFTs) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases and are thought to underlie a number of visual processing skills, including reading. Here, we compare the impact of two vision-training approaches, one involving contrast sensitivity training and the other directional dot-motion training, compared to an active control group trained on Sudoku. The three training paradigms were compared on their effectiveness for altering CFFT. Directional dot-motion and contrast sensitivity training resulted in significant improvement in CFFT, while the Sudoku group did not yield significant improvement. This finding indicates that dot-motion and contrast sensitivity training similarly transfer to effect changes in CFFT. The results, combined with prior research linking CFFT to high-order cognitive processes such as reading ability, and studies showing positive impact of both dot-motion and contrast sensitivity training in reading, provide a possible mechanistic link of how these different training approaches impact reading abilities.

Although autism spectrum disorder (ASD) is a serious lifelong condition, its underlying neural mechanism remains unclear. Recently, neuroimaging-based classifiers for ASD and typically developed (TD) individuals were developed to identify the abnormality of functional connections (FCs). Due to over-fitting and interferential effects of varying measurement conditions and demographic distributions, no classifiers have been strictly validated for independent cohorts. Here we overcome these difficulties by developing a novel machine-learning algorithm that identifies a small number of FCs that separates ASD versus TD. The classifier achieves high accuracy for a Japanese discovery cohort and demonstrates a remarkable degree of generalization for two independent validation cohorts in the USA and Japan. The developed ASD classifier does not distinguish individuals with major depressive disorder and attention-deficit hyperactivity disorder from their controls but moderately distinguishes patients with schizophrenia from their controls. The results leave open the viable possibility of exploring neuroimaging-based dimensions quantifying the multiple-disorder spectrum.

Visual perceptual learning (VPL) is defined as visual performance improvement after visual experiences. VPL is often highly specific for a visual feature presented during training. Such specificity is observed in behavioral tuning function changes with the highest improvement centered on the trained feature and was originally thought to be evidence for changes in the early visual system associated with VPL. However, results of neurophysiological studies have been highly controversial concerning whether the plasticity underlying VPL occurs within the visual cortex. The controversy may be partially due to the lack of observation of neural tuning function changes in multiple visual areas in association with VPL. Here using human subjects we systematically compared behavioral tuning function changes after global motion detection training with decoded tuning function changes for 8 visual areas using pattern classification analysis on functional magnetic resonance imaging (fMRI) signals. We found that the behavioral tuning function changes were extremely highly correlated to decoded tuning function changes only in V3A, which is known to be highly responsive to global motion with human subjects. We conclude that VPL of a global motion detection task involves plasticity in a specific visual cortical area.

Objectives: While PhD dissertations are typically accessible as part of a university library’s general collection, or as content within a proprietary database, many other terminal degree projects remain invisible and inaccessible to a greater audience. This poster will describe the development and creation of a digital repository collection containing doctor of nursing practice (DNP) student’s final projects.

Methods: The “Doctor of Nursing Practice (DNP) Final Projects Collection” was created over the course of one semester and included initial discussions with program faculty and administrators, the creation of a student consent form, the development of a process for adding student work to the repository collection, and a presentation to graduating students. This poster will describe the process in more detail, discuss benefits and challenges, as well as highlight the considerations to keep in mind when developing and creating a digital collection of student work. Additionally, best practices and lessons learned will also be described to provide valuable information to others considering creating this type of collection at their own institution.

Results: At the end of the first semester of implementation, twenty student projects existed in our public collection. On the whole, both faculty and students were pleased to have a collection highlighting the work being done in their program. Valuable lessons were learned that can be applied in the next semester of implementation. Specifically, metadata consistency was an issue during the initial uploading process. Gaining select faculty and student buy-in by allaying concerns related to some student’s wanting to publish in a peer-reviewed journal on the topic of their final project remains vital.

Conclusion: Creating open access collections of student applied final projects or capstone projects allows for greater visibility of this type of often overlooked student scholarship. Specifically, the final projects showcased can now be found and accessed by potential employers, researchers, other schools, and other DNP students. In many cases these final projects have applied real-world impact related to answering clinical questions or patient care that should be shared with the world.

This essay uses census data from the eighteenth century to examine the leadership role of caciques in the Guaraní missions. Cacique succession between 1735 and 1759 confirms that the position of cacique transitioned from the Guaraníes’ flexible interpretation of hereditary succession to the Jesuits’ rigid idea of primogenitor (father to eldest son) succession. This essay argues that scholars overstate the caciques’ leadership role in the Guaraní missions. Adherence to primogenitor succession did not take into account a candidate's leadership qualities, and thus, some caciques functioned as placeholders for organizing the mission population and calculating tribute and not as active leaders. An assortment of other Guaraní leadership positions compensated for this weakness by providing both access to leadership roles for non-caciques who possessed leadership qualities but not the proper bloodline and additional leadership opportunities for more capable caciques. By taking into account leadership qualities and not just descent, these positions provided flexibility and reflected continuity with pre-contact Guaraní ideas about leadership.

While PhD dissertations are typically accessible many other terminal degree projects remain invisible and inaccessible to a greater audience. Over the past year and a half, librarians at Arizona State University collaborated with faculty and departmental administrators across a variety of fields to develop and create institutional repository collections that highlight and authoritatively share this type of student scholarship with schools, researchers, and future employers. This poster will present the benefits, challenges, and considerations required to successfully implement and manage these collections of applied final projects or capstone projects. Specifically, issues/challenges related to metadata consistency, faculty buy-in, and developing an ingest process, as well as benefits related to increased visibility and improved educational and employment opportunities will be discussed. This interactive presentation will also discuss lessons learned from the presenter’s experiences in context of how they can easily apply to benefit their respective institutions.

Objectives: With more and more of our students enrolling in online degree programs and attending class virtually we as librarians must ensure that we are providing the same level of education, content, and service to these online students as we do to our in-person students. This poster will describe the development and implementation of multiple library modules across a 100% online RN-BSN nursing program at a large public institution.

Methods: The librarian met with and worked with instructors across three courses in the online RN-BSN program to discuss and examine current library content and instruction that already existed in these classes, as well as the need for new content and modules. An instructional scaffolding approach was settled on, where new content would be introduced progressively to students over the course of three semesters in three separate consecutive courses. In previous semesters, many faculty simply chose their own library content, linked only to the general tutorials page, or lacked any library content at all, making a new structured approach even more necessary. This poster will describe the development of these library modules in more detail, including software used and best practices, and will also focus on the implementation and lessons learned.

Results: A total of five new modules were implemented in the first two classes, while current library tutorials were kept in the third class in the sequence. The modules focused on teaching the students information literacy and database searching skills.

Conclusion: Sequencing library modules over the course of multiple semesters allowed students to build upon core knowledge that is necessary to successfully complete increasingly advanced assignments and gain research skills that can be applied in their future careers as nurses.

Patron Driven Acquisition (PDA) is a growing method of collection development in academic libraries that follows a Just-In-Time model versus the more traditional Just-In-Case model. Arizona State University (ASU) implemented our current PDA plan and profiles in 2009 with minimal changes occurring since this initial implementation date. Our PDA model of collection development involves purchasing print and e-books when users select them in the online catalog, rather than receiving items on an approval plan or by librarian selection. After an initial investigation concluded that several major health sciences publications had not been loaded into the catalog for potential patron selection, we began a more thorough examination of our PDA profile.

ASU serves over 6,500 students, faculty, and staff in Nursing and Allied Health fields in a range of programs requiring a robust collection. This poster details the process we used to determine whether the profiles created by previous librarians in 2009 have succeeded in uploading records for publications that appear on the 2014 nursing texts from Doody’s Core Titles into our catalog. Specifically, our poster will present on the number of Doody’s titles that were excluded from the PDA plan due to our profile settings and analyze why these titles were excluded. Our findings will allow us to order titles that are currently missing from our collection as well as tailor our PDA profiles to include key texts in nursing and allied health subjects in the future. We will also provide recommendations and considerations for other libraries considering or using a PDA model for purchasing texts in the health sciences.
