Developing Communities of Practice in Tertiary Education: Improving Teaching and Learning
Get PDFThere is considerable evidence that the development of Communities of Practice (CoP) in education results in improvements in teaching and learning. The reality far too often, however, is that academics remain isolated in their practice with a culture of individualism rather than collaboration the norm. Adopting a case study approach, this research explores the perspectives of academic staff in one department in Cork Institute of Technology (CIT) on CoP. Specifically, the research explores how communities of practice might develop in a third level teaching environment; the type and nature of communities of practice that might develop and if those communities of practice have a resulting impact on teaching and learning. The findings indicate that not only is there an enthusiasm for collaboration and the development of CoP, but that moreover is something that would be welcomed by staff in the department. The research concludes that a significant opportunity now exists to stimulate and support the development of CoP among educators; a move which would have the twofold benefit of both motivating staff and enhancing the student experience
Irish local and artisan foods: Multiples make space!
Get PDFConsumers are now bombarded with marketing messages in relation to food choice and consumption, but modern day consumers are very concerned with the food chain and have become discerning about their food choices.
This research examines “Local and Artisan” food choices and finds that consumers in general would like to have easy access to such products. While traditionally found at farmers’ markets, now everyday access is sought through Supermarkets. The researchers were fortunate in having access to a large supermarket rewards programme database where 14,646 supermarket shoppers responded. The study finds that Local and Artisan food products are desired by shoppers and will warrant space on the shelves of supermarkets.
This research examines what local and artisan foods mean to the consumers and how they are interpreted and understood by consumers.
Also, both “where our food actually comes from”, and the importance of this information to the consumer is interpreted
A Luminous and Isolated Gamma-Ray Flare from the Blazar B2 1215+30
Get PDFB2 1215+30 is a BL-Lac-type blazar that was first detected at TeV energies by the MAGIC atmospheric Cherenkov telescopes and subsequently confirmed by the Very Energetic Radiation Imaging Telescope Array System (VERITAS) observatory with data collected between 2009 and 2012. In 2014 February 08, VERITAS detected a large-amplitude flare from B2 1215+30 during routine monitoring observations of the blazar 1ES 1218+304, located in the same field of view. The TeV flux reached 2.4 times the Crab Nebula flux with a variability timescale of . Multiwavelength observations with Fermi-LAT, Swift, and the Tuorla Observatory revealed a correlated high GeV flux state and no significant optical counterpart to the flare, with a spectral energy distribution where the gamma-ray luminosity exceeds the synchrotron luminosity. When interpreted in the framework of a one-zone leptonic model, the observed emission implies a high degree of beaming, with Doppler factor , and an electron population with spectral index
Gamma-Ray Observations Of Tycho\u27s Supernova Remnant With Veritas And Fermi
Get PDFHigh-energy gamma-ray emission from supernova remnants (SNRs) has provided a unique perspective for studies of Galactic cosmic-ray acceleration. Tycho\u27s SNR is a particularly good target because it is a young, type Ia SNR that has been well-studied over a wide range of energies and located in a relatively clean environment. Since the detection of gamma-ray emission from Tycho\u27s SNR by VERITAS and Fermi-LAT, there have been several theoretical models proposed to explain its broadband emission and high-energy morphology. We report on an update to the gamma-ray measurements of Tycho\u27s SNR with 147 hr of VERITAS and 84 months of Fermi-LAT observations, which represent about a factor of two increase in exposure over previously published data. About half of the VERITAS data benefited from a camera upgrade, which has made it possible to extend the TeV measurements toward lower energies. The TeV spectral index measured by VERITAS is consistent with previous results, but the expanded energy range softens a straight power-law fit. At energies higher than 400 GeV, the power-law index is 2.92 ± 0.42stat ± 0.20sys. It is also softer than the spectral index in the GeV energy range, 2.14 ± 0.09stat ± 0.02sys, measured in this study using Fermi-LAT data. The centroid position of the gamma-ray emission is coincident with the center of the remnant, as well as with the centroid measurement of Fermi-LAT above 1 GeV. The results are consistent with an SNR shell origin of the emission, as many models assume. The updated spectrum points to a lower maximum particle energy than has been suggested previously

Discovery of Very-high-energy Emission from RGB J2243+203 and Derivation of Its Redshift Upper Limit
Get PDFVery-high-energy (VHE; \u3e 100 GeV) gamma-ray emission from the blazar RGB J2243+203 was discovered with the VERITAS Cherenkov telescope array, during the period between 2014 December 21 and 24. The VERITAS energy spectrum from this source can be fitted by a power law with a photon index of 4.6 ± 0.5, and a flux normalization at 0.15 TeV of . The integrated Fermi-LAT flux from 1 to 100 GeV during the VERITAS detection is , which is an order of magnitude larger than the four-year-averaged flux in the same energy range reported in the 3FGL catalog, (). The detection with VERITAS triggered observations in the X-ray band with the Swift-XRT. However, due to scheduling constraints Swift-XRT observations were performed 67 hr after the VERITAS detection, rather than simultaneously with the VERITAS observations. The observed X-ray energy spectrum between 2 and 10 keV can be fitted with a power law with a spectral index of 2.7 ± 0.2, and the integrated photon flux in the same energy band is . EBL-model-dependent upper limits of the blazar redshift have been derived. Depending on the EBL model used, the upper limit varies in the range from z to z
The Association of Serum Levels of Brain-Derived Neurotrophic Factor with the Occurrence of and Recovery from Delirium in Older Medical Inpatients
Get PDFLimited studies of the association between BDNF levels and delirium have given inconclusive results. This prospective, longitudinal study examined the relationship between BDNF levels and the occurrence of and recovery from delirium. Participants were assessed twice weekly using MoCA, DRS-R98, and APACHE II scales. BDNF levels were estimated using an ELISA method. Delirium was defined with DRS-R98 (score \u3e 16) and recovery from delirium as ≥2 consecutive assessments without delirium prior to discharge. We identified no difference in BDNF levels between those with and without delirium. Excluding those who never developed delirium (), we examined the association of BDNF levels and other variables with delirium recovery. Of 58 who experienced delirium, 39 remained delirious while 19 recovered. Using Generalized Estimating Equations models we found that BDNF levels (Wald ; df: 1, ) and MoCA (Wald ; df: 1, ) were associated with recovery. No significant association was found for APACHE II, dementia, age, or gender. BDNF levels do not appear to be directly linked to the occurrence of delirium but recovery was less likely in those with continuously lower levels. No previous study has investigated the role of BDNF in delirium recovery and these findings warrant replication in other populations
A Decision Support Tool for Building Integrated Renewable Energy Microgrids Connected to a Smart Grid
Get PDFThe objective of this study was to create a tool that will enable renewable energy microgrid (REμG) facility users to make informed decisions on the utilization of electrical power output from a building integrated REμG connected to a smart grid. A decision support tool for renewable energy microgrids (DSTREM) capable of predicting photovoltaic array and wind turbine power outputs was developed. The tool simulated users’ daily electricity consumption costs, avoided CO2 emissions and incurred monetary income relative to the usage of the building integrated REμG connected to the national electricity smart grid. DSTREM forecasted climate variables, which were used to predict REμG power output over a period of seven days. Control logic was used to prioritize supply of electricity to consumers from the renewable energy sources and the national smart grid. Across the evaluated REμG electricity supply options and during working days, electricity exported by the REμG to the national smart grid ranged from 0% to 61% of total daily generation. The results demonstrated that both monetary saving and CO2 offsets can be substantially improved through the application of DSTREM to a REμG connected to a building
The sociodemographic indicators of travel insurance fraud: motivations, emotions, and behaviours
Get PDFThis work centres on the study of travel insurance fraud, with the aim of identifying the psychographic and behavioural responses involved in claiming an insurance policy through simulating injury or loss. To be specific, five types of motivation (fun, compensation, revenge, profitability, and family interest), nine types of emotion (love, surprise, disgust, anger, shame, sadness, trust, fear, and pride), and three types of behaviour (without personal damages, at destination, and with personal damages) have been found to be related to travel insurance fraud. In order to facilitate the detection of dishonest claims, the relationship between these psychographic, as well as behavioural features, and four sociodemographic variables, have been visualised - principally gender, age and education, and, to a lesser extent, income. Therefore, the results of the empirical survey carried out on a sample of 334 travel insurance policy holders and following a snow ball procedure not only give insight into dishonest motivations and conduct, but also make it possible to detect this kind of fraud
Food Tourism in Cork’s English Market - an Authentic Visitor Experience
Get PDFAuthenticity is deemed to be a crucial element in many tourism experiences. Tourism, however, is often accused of succumbing to notions of perceived authenticity to ensure commercial success, leading to misrepresentations of cultures. Food tourism, conversely, is advocated as a means of encountering genuine culture, history and lifestyle. This paper investigates the role of food tourism as an authentic representation of culture in Cork’s English Market. In-depth interviews were conducted with market traders and analysed through the grounded theory method. Results indicate that, allowing for natural evolution, food tourism is providing a platform for the continuation, sharing and development of traditions, therefore offering an authentic cultural experience
