Harnessing the creativity of digital multimedia tools in distance learning
Over the past few decades, advances in information and communication technologies, and particularly the digitisation of information, have brought about radical changes in the way media can be produced, distributed and shared. The exchange of information, once predominately the domain of the written word, now also embraces the digital technologies of audio and video. User-generated multimedia content proliferates, and the presence of audio and video adds dimensions that greatly increase the amount of information an audience can assimilate, adding a richness and depth to the messages we want to convey.
This paper presents and discusses a creative approach to the use of digital multimedia production tools incorporated in the Open Universityâs 60 credit level 2 module, T215 Communication and Information Technologies. These tools are used in a way that:
- explores new ways to help people understand technical concepts;
- supports the development of studentsâ technical skills;
- provides opportunities for students to be creative;
- provides an alternative to traditional text-based assessment.
We briefly explain the key decisions made by the module team during the design stages of the teaching materials and explain the common assessment framework used throughout the different blocks of the module. We then draw on the experience of two presentations of the module, each attracting around 500 students, to examine how students have engaged with the video creation activities and to identify issues that arise in supporting students for these tasks in a distance learning environment. Finally we discuss the success of the assessment task: a 30-second video designed to explain a technical concept related to one of the module topics
Blueprint for a Solid Information Literacy Foundation: Building a Program from the Ground Up
Belmont University\u27s information literacy plan includes three initiatives: 1) integrate information literacy into the curriculum; 2) enhance the educational environment in the library; and 3) strengthen collaboration on information literacy goals. The plan has produced an integrated General Education/information literacy curriculum, an inviting library study and research space, and collaboration on a course ranking scale that measures library resource needs. Liaison librarians work with department chairs to complete the scale, and the rankings are factored into the budget allocation formula for the upcoming fiscal year. This session will describe the process by which this program was developed, from its beginnings to the present, and expectations for future growth. Descriptions of the curricular components, sample lesson activities, and the course ranking scale will be provided. After attending this session, participants will be able to:
-Identify key players at their institutions whose support will enable an information literacy program to go forward
-Identify common courses into which information literacy might be integrated
-Identify possible collaborative partners
-Sketch out learning outcomes unique to each common course
-Envision new and more productive uses for library space
-Create new liaison roles for librarian
Setting Sail without a Map: Creative Collaboration for a Multi-Disciplinary Conference
The Art of the Picture Book Conference was launched in May 2006 in Ashland, Ohio. The two-day event drew a total of 158 attendees, featured award-winning authors/ illustrators as keynote speakers, and offered 35 sessions, selected from a total of 45 proposal submissions. By involving co-curricular programs and community partners, such as other departments on campus, the university bookstore, local public libraries and school districts, and regional museums, the conference offered a variety of techniques to develop and enhance literacy in children. Presentation opportunities allowed our university students a venue to showcase their comprehensive information abilities. Crossover into various disciplines created wide interest and networking opportunities, and increased library visibility across campus. Learn how we navigated these murky waters without a map and realized the benefits of venturing beyond the protected waters of the academic library.
This session will provide insight into general conference planning skills, such as timelines, schedules, delegation of duties, cross-disciplinary communication, and backup plans. These skills are applicable to workshops and smaller events as well. We will also focus on the unexpected challenges and rewarding opportunities of working closely with university colleagues and with partners outside of the library and academia. Participants will be invited to share their own experiences with conference/workshop planning, and will have an opportunity to brainstorm ideas for new collaborative partnerships on their campuses and within their communities. Timelines and checklists of tasks for successful conference planning will be provided
A systematic review of air pollution and incidence of out-of-hospital cardiac arrest
Introduction: Studies have linked air pollution with the incidence of acute coronary artery events and cardiovascular mortality but the association with out-of-hospital cardiac arrest (OHCA) is less clear. Aim: To examine the association of air pollution with the occurrence of OHCA.Methods: Electronic bibliographic databases (until February 2013) were searched. Search terms included common air pollutants and OHCA. Studies of patients with implantable cardioverter defibrillators and OHCA not attended by paramedics were excluded. Two independent reviewers (THKT and TAW) identified potential studies. Methodological: quality was assessed by the Newcastle-Ottawa Scale.Results: Of 849 studies, 8 met the selection criteria. Significant associations between particulate matter (PM) exposure (especially PM2.5) and OHCA were found in 5 studies. An increase of OHCA risk ranged from 2.4% to 7% per interquartile increase in average PM exposure on the same day and up to 4 days prior to the event. A large study found ozone increased the risk of OHCA within 3 h prior to the event. The strongest risk OR of 3.8â4.6% per 20 parts per billion ozone increase of the average level was within 2 h prior to the event. Similarly, another study found an increased risk of 18% within 2 days prior to the event.Conclusions: Larger studies have suggested an increased risk of OHCA with air pollution exposure from PM 2.5 and ozone
Human and murine IFIT1 proteins do not restrict infection of negative-sense RNA viruses of the Orthomyxoviridae, Bunyaviridae, and Filoviridae families
UNLABELLED: Interferon-induced protein with tetratricopeptide repeats 1 (IFIT1) is a host protein with reported cell-intrinsic antiviral activity against several RNA viruses. The proposed basis for the activity against negative-sense RNA viruses is the binding to exposed 5\u27-triphosphates (5\u27-ppp) on the genome of viral RNA. However, recent studies reported relatively low binding affinities of IFIT1 for 5\u27-ppp RNA, suggesting that IFIT1 may not interact efficiently with this moiety under physiological conditions. To evaluate the ability of IFIT1 to have an impact on negative-sense RNA viruses, we infected Ifit1(-/-) and wild-type control mice and primary cells with four negative-sense RNA viruses (influenza A virus [IAV], La Crosse virus [LACV], Oropouche virus [OROV], and Ebola virus) corresponding to three distinct families. Unexpectedly, a lack of Ifit1 gene expression did not result in increased infection by any of these viruses in cell culture. Analogously, morbidity, mortality, and viral burdens in tissues were identical between Ifit1(-/-) and control mice after infection with IAV, LACV, or OROV. Finally, deletion of the human IFIT1 protein in A549 cells did not affect IAV replication or infection, and reciprocally, ectopic expression of IFIT1 in HEK293T cells did not inhibit IAV infection. To explain the lack of antiviral activity against IAV, we measured the binding affinity of IFIT1 for RNA oligonucleotides resembling the 5\u27 ends of IAV gene segments. The affinity for 5\u27-ppp RNA was approximately 10-fold lower than that for non-2\u27-O-methylated (cap 0) RNA oligonucleotides. Based on this analysis, we conclude that IFIT1 is not a dominant restriction factor against negative-sense RNA viruses.
IMPORTANCE: Negative-sense RNA viruses, including influenza virus and Ebola virus, have been responsible for some of the most deadly outbreaks in recent history. The host interferon response and induction of antiviral genes contribute to the control of infections by these viruses. IFIT1 is highly induced after virus infection and reportedly has antiviral activity against several RNA and DNA viruses. However, its role in restricting infection by negative-sense RNA viruses remains unclear. In this study, we evaluated the ability of IFIT1 to inhibit negative-sense RNA virus replication and pathogenesis both in vitro and in vivo. Detailed cell culture and animal studies demonstrated that IFIT1 is not a dominant restriction factor against three different families of negative-sense RNA viruses
The Initial Configuration of Young Stellar Clusters: A K-band Number Counts Analysis of the Surface Density of Stars
We present an analysis of K-band stellar distributions for the young stellar
clusters GGD 12-15, IRAS 20050+2720, and NGC 7129. We find that the two deeply
embedded clusters, GGD 12-15 and IRAS 20050+2720, are not azimuthally symmetric
and show a high degree of structure which traces filamentary structure observed
in 850 micron emission maps. In contrast, the NGC 7129 cluster is circularly
symmetric, less dense, and anti-correlated to 850 micron emission, suggesting
recent gas expulsion and dynamical expansion have occured. We estimate stellar
volume densities from nearest neighbor distances, and discuss the impact of
these densities on the evolution of circumstellar disks and protostellar
envelopes in these regions.Comment: 44 pages, 26 figures, Accepted to ApJ. Changes include extinction
mapping, Monte Carlo field star modeling, and Nyquist sampled azimuthal
stellar distributions. A version with full resolution figures is available at

Spitzer, Near-Infrared, and Submillimeter Imaging of the Relatively Sparse Young Cluster, Lynds 988e
We present {\it Spitzer} images of the relatively sparse, low luminosity
young cluster L988e, as well as complementary near-infrared (NIR) and
submillimeter images of the region. The cluster is asymmetric, with the western
region of the cluster embedded within the molecular cloud, and the slightly
less dense eastern region to the east of, and on the edge of, the molecular
cloud. With these data, as well as with extant H data of stars
primarily found in the eastern region of the cluster, and a molecular CO
gas emission map of the entire region, we investigate the distribution of
forming young stars with respect to the cloud material, concentrating
particularly on the differences and similarities between the exposed and
embedded regions of the cluster. We also compare star formation in this region
to that in denser, more luminous and more massive clusters already investigated
in our comprehensive multi-wavelength study of young clusters within 1 kpc of
the Sun.Comment: 21 pages, 6 tables, 13 figures. Full resolution figures at:

Which patients should be transported to the emergency department? A perpetual prehospital dilemma
Objective: To examine the ability of paramedics to identify patients who could be managed in the community and to identify predictors that could be used to accurately identify patients who should be transported to EDs. Methods: Lower acuity patients who were assessed by paramedics in the Perth metropolitan area in 2013 were studied. Paramedics prospectively indicated on the patient care record if they considered that the patient could be treated in the community. The paramedic decisions were compared with actual disposition from the ED (discharge and admission), and the occurrence of subsequent events (ambulance request, ED visit, admission and death) for discharged patients at the scene was investigated. Decision tree analysis was used to identify predictors that were associated with hospital admission. Results: In total, 57183 patients were transported to the ED, and 10204 patients were discharged at the scene by paramedics. Paramedics identified 2717 patients who could potentially be treated in the community among those who were transported to the ED. Of these, 1455 patients (53.6%) were admitted to hospital. For patients discharged at the scene, those who were indicated as suitable for community care were more likely to experience subsequent events than those who were not. The decision tree found that two predictors (age and aetiology) were associated with hospital admission. Overall discriminative power of the decision tree was poor; the area under the receiver operating characteristic curve was 0.686. Conclusion: Lower acuity patients who could be treated in the community were not accurately identified by paramedics.

Detection of Low Frequency Multi-Drug Resistance and Novel Putative Maribavir Resistance in Immunocompromised Pediatric Patients with Cytomegalovirus.
Human cytomegalovirus (HCMV) is a significant pathogen in immunocompromised individuals, with the potential to cause fatal pneumonitis and colitis, as well as increasing the risk of organ rejection in transplant patients. With the advent of new anti-HCMV drugs there is therefore considerable interest in using virus sequence data to monitor emerging resistance to antiviral drugs in HCMV viraemia and disease, including the identification of putative new mutations. We used target-enrichment to deep sequence HCMV DNA from 11 immunosuppressed pediatric patients receiving single or combination anti-HCMV treatment, serially sampled over 1-27 weeks. Changes in consensus sequence and resistance mutations were analyzed for three ORFs targeted by anti-HCMV drugs and the frequencies of drug resistance mutations monitored. Targeted-enriched sequencing of clinical material detected mutations occurring at frequencies of 2%. Seven patients showed no evidence of drug resistance mutations. Four patients developed drug resistance mutations a mean of 16 weeks after starting treatment. In two patients, multiple resistance mutations accumulated at frequencies of 20% or less, including putative maribavir and ganciclovir resistance mutations P522Q (UL54) and C480F (UL97). In one patient, resistance was detected 14 days earlier than by PCR. Phylogenetic analysis suggested recombination or superinfection in one patient. Deep sequencing of HCMV enriched from clinical samples excluded resistance in 7 of 11 subjects and identified resistance mutations earlier than conventional PCR-based resistance testing in 2 patients. Detection of multiple low level resistance mutations was associated with poor outcome
