The Perceived Impact of Information Technology Experiential Learning on Career Success: A Pilot Study

Employers in the Information Technology field place significant value on the amount of real-­world experience prospective employees possess. Recent IT graduates face a competitive job market against seasoned professionals with years of experience. Students must build a solid experience base from which they can advance professionally. This cannot be done without first holding an IT position. The key to solving the experience paradox is experiential learning – the process of learning by doing. The Living Lab at is a non-­traditional undergraduate course based on the concept of experiential learning in the field of Information Technology. The Living Lab is structured similarly to a corporate IT department, with students playing the role of IT personnel. Students learn to apply their previous course material and gain resume-­worthy experience, while working in teams to complete IT projects for their university and local businesses. Projects are fully documented and reported on throughout the course with a final presentation at semester end. This study investigates what, if any, benefit graduates gain from the Living Lab experience. Graduates who were involved in the Living Lab were electronically surveyed about their professional careers after college. Questions focused on how the student felt their time in Living Lab helped them gain employment and enhance their ability to perform as an employee. Results will be used to gauge the validity of the Living Lab program and experiential learning as an effective tool in terms of IT education. Data from this study can be used to improve the program, and help prospective students to make an informed decision when considering the Living Lab. Ultimately, other institutions may be encouraged to consider implementing a Living Lab or similar IT experiential learning environment of their own

Developing an Online Critical Care Electroencephalography Curriculum for Epilepsy and Neurophysiology Fellows

Purpose: This project aims to create an Electroencephalography (EEG) curriculum that synthesizes the teachings of current publications and faculty expertise within a single digital platform. The goal is to remedy the unmet need for a centralized resource for learners to use when learning EEG interpretation. Methods: The target learner population is epilepsy and neurophysiology fellows. The platform will be accessible from any computer, tablet, or phone, allowing for mobile, self-paced learning to take place. To date, the curriculum outline has been designed with extensive literature review and collaboration from other institutions, and two pilot modules have been completed using the story-board platform Articulate. Data about efficacy and usefulness will be collected via learner feedback forms when the program goes live. Results and Conclusions: We anticipate that fellows will appreciate the streamlined approach to learning high-yield topics in EEG interpretation. The hope is that the platform will save users time currently spent sifting through textbooks and publications because it incorporates a conglomerate of resources, including qualitative input from experts across the country. That time, in turn, can be spent with more targeted interactions with their teachers (the platform serves as a complement to the existing face-to-face instruction). Learning activities for progress-evaluation will be embedded within each module of the platform with the goal of allowing learners to self-identify areas of improvement to help focus studying efforts. Further results and conclusions will be recorded and updated as progress continues to be made

Low prevalence of methicillin-resistant Staphylococcus aureus nasal carriage in urban and rural community settings in Bolivia and Peru☆

Summary Objective To investigate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage in rural and urban community settings of Bolivia and Peru. Methods MRSA nasal carriage was investigated in 585 individuals living in rural and urban areas of Bolivia and Peru (one urban area, one small rural village, and two native communities, one of which was highly isolated). MRSA isolates were subjected to molecular analysis for the detection of virulence genes, characterization of the staphylococcal cassette chromosome mec (SCC mec ), and genotyping (multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE)). Results An overall very low prevalence of MRSA nasal carriage was observed (0.5%), with MRSA carriers being detected only in a small rural village of the Bolivian Chaco. The three MRSA isolates showed the characteristics of community-associated MRSA (being susceptible to all non-beta-lactam antibiotics and harboring the SCC mec type IV), were clonally related, and belonged to ST1649. Conclusions This study provides an insight into the epidemiology of MRSA in community settings of Bolivia and Peru. Reliable, time-saving, and low-cost methods should be implemented to encourage continued surveillance of MRSA dissemination in resource-limited countries

Elevated white cell count in acute coronary syndromes: relationship to variants in inflammatory and thrombotic genes

BACKGROUND: Elevated white blood cell counts (WBC) in acute coronary syndromes (ACS) increase the risk of recurrent events, but it is not known if this is exacerbated by pro-inflammatory factors. We sought to identify whether pro-inflammatory genetic variants contributed to alterations in WBC and C-reactive protein (CRP) in an ACS population. METHODS: WBC and genotype of interleukin 6 (IL-6 G-174C) and of interleukin-1 receptor antagonist (IL1RN intronic repeat polymorphism) were investigated in 732 Caucasian patients with ACS in the OPUS-TIMI-16 trial. Samples for measurement of WBC and inflammatory factors were taken at baseline, i.e. Within 72 hours of an acute myocardial infarction or an unstable angina event. RESULTS: An increased white blood cell count (WBC) was associated with an increased C-reactive protein (r = 0.23, p < 0.001) and there was also a positive correlation between levels of β-fibrinogen and C-reactive protein (r = 0.42, p < 0.0001). IL1RN and IL6 genotypes had no significant impact upon WBC. The difference in median WBC between the two homozygote IL6 genotypes was 0.21/mm(3 )(95% CI = -0.41, 0.77), and -0.03/mm(3 )(95% CI = -0.55, 0.86) for IL1RN. Moreover, the composite endpoint was not significantly affected by an interaction between WBC and the IL1 (p = 0.61) or IL6 (p = 0.48) genotype. CONCLUSIONS: Cytokine pro-inflammatory genetic variants do not influence the increased inflammatory profile of ACS patients

Search for coherent elastic neutrino-nucleus scattering at a nuclear reactor with CONNIE 2019 data

The Coherent Neutrino-Nucleus Interaction Experiment (CONNIE) is taking data at the Angra 2 nuclear reactor with the aim of detecting the coherent elastic scattering of reactor antineutrinos with silicon nuclei using charge-coupled devices (CCDs). In 2019 the experiment operated with a hardware binning applied to the readout stage, leading to lower levels of readout noise and improving the detection threshold down to 50 eV. The results of the analysis of 2019 data are reported here, corresponding to the detector array of 8 CCDs with a fiducial mass of 36.2 g and a total exposure of 2.2 kg-days. The difference between the reactor-on and reactor-off spectra shows no excess at low energies and yields upper limits at 95% confidence level for the neutrino interaction rates. In the lowest-energy range, 50-180 eV, the expected limit stands at 34 (39) times the standard model prediction, while the observed limit is 66 (75) times the standard model prediction with Sarkis (Chavarria) quenching factors.Comment: 23 pages, 14 figure

Understanding the Use of Crisis Informatics Technology among Older Adults

Mass emergencies increasingly pose significant threats to human life, with a disproportionate burden being incurred by older adults. Research has explored how mobile technology can mitigate the effects of mass emergencies. However, less work has examined how mobile technologies support older adults during emergencies, considering their unique needs. To address this research gap, we interviewed 16 older adults who had recent experience with an emergency evacuation to understand the perceived value of using mobile technology during emergencies. We found that there was a lack of awareness and engagement with existing crisis apps. Our findings characterize the ways in which our participants did and did not feel crisis informatics tools address human values, including basic needs and esteem needs. We contribute an understanding of how older adults used mobile technology during emergencies and their perspectives on how well such tools address human values.Comment: 10 page

Evenness mediates the global relationship between forest productivity and richness

1. Biodiversity is an important component of natural ecosystems, with higher species richness often correlating with an increase in ecosystem productivity. Yet, this relationship varies substantially across environments, typically becoming less pronounced at high levels of species richness. However, species richness alone cannot reflect all important properties of a community, including community evenness, which may mediate the relationship between biodiversity and productivity. If the evenness of a community correlates negatively with richness across forests globally, then a greater number of species may not always increase overall diversity and productivity of the system. Theoretical work and local empirical studies have shown that the effect of evenness on ecosystem functioning may be especially strong at high richness levels, yet the consistency of this remains untested at a global scale. 2. Here, we used a dataset of forests from across the globe, which includes composition, biomass accumulation and net primary productivity, to explore whether productivity correlates with community evenness and richness in a way that evenness appears to buffer the effect of richness. Specifically, we evaluated whether low levels of evenness in speciose communities correlate with the attenuation of the richness–productivity relationship. 3. We found that tree species richness and evenness are negatively correlated across forests globally, with highly speciose forests typically comprising a few dominant and many rare species. Furthermore, we found that the correlation between diversity and productivity changes with evenness: at low richness, uneven communities are more productive, while at high richness, even communities are more productive. 4. Synthesis. Collectively, these results demonstrate that evenness is an integral component of the relationship between biodiversity and productivity, and that the attenuating effect of richness on forest productivity might be partly explained by low evenness in speciose communities. Productivity generally increases with species richness, until reduced evenness limits the overall increases in community diversity. Our research suggests that evenness is a fundamental component of biodiversity– ecosystem function relationships, and is of critical importance for guiding conservation and sustainable ecosystem management decisions
