Restaurant Selection in Dublin

The primary objective of this research was to investigate the selection process used by consumers when choosing a restaurant to dine. This study examined literature on consumer behaviour, restaurant selection, and decision-making, underpinning the contention that service quality is linked to the consumer’s selection of a restaurant. It supports the utility theories that consumers buy bundles of attributes that simultaneously combined represent a certain level of service quality at a certain price. The findings of the research displayed a preference by Dublin consumers for Italian and Chinese styled restaurants and identified quality of the food, type of food, cleanliness of the restaurant, location and the reputation of the restaurant as the key decision variables/attributes used by consumers to select restaurants. The study also established that the importance of the attributes changed, depending on the consumer’s age, prior experience, their mood and the occasion involved

An Investigation in the Development of Europe\u27s Erasmus Internship Policy

The involvement of the School of Culinary Arts and Food Technology in international mobility for work placement has experienced exponential growth over the past five years with the assistance of European Leonardo da Vinci and Erasmus funding for European internships. The main purpose behind the European Commission funding ventures for internship (experiential learning) is to enhance the students’ cultural awareness, cultivate their language skills and develop their professionalism in their field of study. This paper provide an overview of the development of Erasmus internship and relationship between the the European Commission, the HEA, and DIT

Developing a Pedagogic Approach to Enhance Student Learning Before, During and After International Work Placement: Teaching Fellowship 11

The report commences with a brief overview of the Fellowship research and provides insight into the benefits of mobility. Erasmus mobility is viewed as a means to promote the Department of Culinary Arts in the international culinary arena via the student’s skills and performance. It is clear from this research that the international internships provide exceptional opportunities for students to integrate and learn in different cultural environments. It is argued that this research addresses many of the unanswered issues related to internship before, during and after the experience: issues of knowledge, identity, integration and the student’s personal development. This research framed the development of an internship model termed “Academic Connection Internship Development “ (ACID) that supports better learning and student development during national and international mobility. The research provided insight, understanding and knowledge in relation to student development and concerns when living and working in another country and internship in general

Compton Scattering of Fe K alpha Lines in Magnetic Cataclysmic Variables

Compton scattering of X-rays in the bulk flow of the accretion column in magnetic cataclysmic variables (mCVs) can significantly shift photon energies. We present Monte Carlo simulations based on a nonlinear algorithm demonstrating the effects of Compton scattering on the H-like, He-like and neutral Fe K alpha lines produced in the post-shock region of the accretion column. The peak line emissivities of the photons in the post-shock flow are taken into consideration and frequency shifts due to Doppler effects are also included. We find that line profiles are most distorted by Compton scattering effects in strongly magnetized mCVs with a low white dwarf mass and high mass accretion rate and which are viewed at an oblique angle with respect to the accretion column. The resulting line profiles are most sensitive to the inclination angle. We have also explored the effects of modifying the accretion column width and using a realistic emissivity profile. We find that these do not have a significant overall effect on the resulting line profiles. A comparison of our simulated line spectra with high resolution Chandra/HETGS observations of the mCV GK Per indicates that a wing feature redward of the 6.4 keV line may result from Compton recoil near the base of the accretion column.Comment: Accepted for publication in MNRAS, 10 pages with 8 figure

Identification of microRNAs expressed in two mosquito vectors, Aedes albopictus and Culex quinquefasciatus

<p>Abstract</p> <p>Background</p> <p>MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression in a variety of organisms, including insects, vertebrates, and plants. miRNAs play important roles in cell development and differentiation as well as in the cellular response to stress and infection. To date, there are limited reports of miRNA identification in mosquitoes, insects that act as essential vectors for the transmission of many human pathogens, including flaviviruses. West Nile virus (WNV) and dengue virus, members of the <it>Flaviviridae </it>family, are primarily transmitted by <it>Aedes </it>and <it>Culex </it>mosquitoes. Using high-throughput deep sequencing, we examined the miRNA repertoire in <it>Ae. albopictus </it>cells and <it>Cx. quinquefasciatus </it>mosquitoes.</p> <p>Results</p> <p>We identified a total of 65 miRNAs in the <it>Ae. albopictus </it>C7/10 cell line and 77 miRNAs in <it>Cx. quinquefasciatus </it>mosquitoes, the majority of which are conserved in other insects such as <it>Drosophila melanogaster </it>and <it>Anopheles gambiae</it>. The most highly expressed miRNA in both mosquito species was miR-184, a miRNA conserved from insects to vertebrates. Several previously reported <it>Anopheles </it>miRNAs, including miR-1890 and miR-1891, were also found in <it>Culex </it>and <it>Aedes</it>, and appear to be restricted to mosquitoes. We identified seven novel miRNAs, arising from nine different precursors, in C7/10 cells and <it>Cx. quinquefasciatus </it>mosquitoes, two of which have predicted orthologs in <it>An. gambiae</it>. Several of these novel miRNAs reside within a ~350 nt long cluster present in both <it>Aedes </it>and <it>Culex</it>. miRNA expression was confirmed by primer extension analysis. To determine whether flavivirus infection affects miRNA expression, we infected female <it>Culex </it>mosquitoes with WNV. Two miRNAs, miR-92 and miR-989, showed significant changes in expression levels following WNV infection.</p> <p>Conclusions</p> <p><it>Aedes </it>and <it>Culex </it>mosquitoes are important flavivirus vectors. Recent advances in both mosquito genomics and high-throughput sequencing technologies enabled us to interrogate the miRNA profile in these two species. Here, we provide evidence for over 60 conserved and seven novel mosquito miRNAs, expanding upon our current understanding of insect miRNAs. Undoubtedly, some of the miRNAs identified will have roles not only in mosquito development, but also in mediating viral infection in the mosquito host.</p

Indications and practical approach to non-invasive ventilation in acute heart failure

In acute heart failure (AHF) syndromes significant respiratory failure (RF) is essentially seen in patients with acute cardiogenic pulmonary oedema (ACPE) or cardiogenic shock (CS). Non-invasive ventilation (NIV), the application of positive intrathoracic pressure through an interface, has shown to be useful in the treatment of moderate to severe RF in several scenarios. There are two main modalities of NIV: continuous positive airway pressure (CPAP) and pressure support ventilation (NIPSV) with positive end expiratory pressure. Appropriate equipment and experience is needed for NIPSV, whereas CPAP may be administered without a ventilator, not requiring special training. Both modalities have shown to be effective in ACPE, by a reduction of respiratory distress and the endotracheal intubation rate compared to conventional oxygen therapy, but the impact on mortality is less conclusive. Non-invasive ventilation is also indicated in patients with AHF associated to pulmonary disease and may be considered, after haemodynamic stabilization, in some patients with CS. There are no differences in the outcomes in the studies comparing both techniques, but CPAP is a simpler technique that may be preferred in low-equipped areas like the pre-hospital setting, while NIPSV may be preferable in patients with significant hypercapnia. The new modality 'high-flow nasal cannula' seems promising in cases of AHF with less severe RF. The correct selection of patients and interfaces, early application of the technique, the achievement of a good synchrony between patients and the ventilator avoiding excessive leakage, close monitoring, proactive management, and in some cases mild sedation, may warrant the success of the technique

Generalized surface current method in the macroscopic theory of diffraction radiation

The surface current method known in the theory of electromagnetic waves diffraction is generalized to be applied for the problems of diffraction radiation generated by a charged particle moving nearby an ideally-conducting screen in vacuum. An expression for induced surface current density leading to the exact results in the theory of transition radiation is derived, and by using this expression several exact solutions of diffraction radiation problems are found. Limits of applicability for the earlier known models based on the surface current conception are indicated. Properties of radiation from a semi-plane and from a slit in cylinder are investigated at the various distances to observer.Comment: 8 pages, 8 figure

A simple analytical method for heterogeneity corrections in low dose rate prostate brachytherapy

In low energy brachytherapy, the presence of tissue heterogeneities contributes significantly to the discrepancies observed between treatment plan and delivered dose. In this work, we present a simplified analytical dose calculation algorithm for heterogeneous tissue. We compare it with Monte Carlo computations and assess its suitability for integration in clinical treatment planning systems. The algorithm, named as RayStretch, is based on the classic equivalent path length method and TG-43 reference data. Analytical and Monte Carlo dose calculations using Penelope2008 are compared for a benchmark case: a prostate patient with calcifications. The results show a remarkable agreement between simulation and algorithm, the latter having, in addition, a high calculation speed. The proposed analytical model is compatible with clinical real-time treatment planning systems based on TG-43 consensus datasets for improving dose calculation and treatment quality in heterogeneous tissue. Moreover, the algorithm is applicable for any type of heterogeneities

Prohormones in the early diagnosis of cardiac syncope

Background--The early detection of cardiac syncope is challenging. We aimed to evaluate the diagnostic value of 4 novel prohormones, quantifying different neurohumoral pathways, possibly involved in the pathophysiological features of cardiac syncope: midregional-pro-A-type natriuretic peptide (MRproANP), C-terminal proendothelin 1, copeptin, and midregionalproadrenomedullin. Methods and Results--We prospectively enrolled unselected patients presenting with syncope to the emergency department (ED) in a diagnostic multicenter study. ED probability of cardiac syncope was quantified by the treating ED physician using a visual analogue scale. Prohormones were measured in a blinded manner. Two independent cardiologists adjudicated the final diagnosis on the basis of all clinical information, including 1-year follow-up. Among 689 patients, cardiac syncope was the adjudicated final diagnosis in 125 (18%). Plasma concentrations of MRproANP, C-terminal proendothelin 1, copeptin, and midregional-proadrenomedullin were all significantly higher in patients with cardiac syncope compared with patients with other causes (P < 0.001). The diagnostic accuracies for cardiac syncope, as quantified by the area under the curve, were 0.80 (95% confidence interval [CI], 0.76-0.84), 0.69 (95% CI, 0.64-0.74), 0.58 (95% CI, 0.52-0.63), and 0.68 (95% CI, 0.63-0.73), respectively. In conjunction with the ED probability (0.86; 95% CI, 0.82-0.90), MRproANP, but not the other prohormone, improved the area under the curve to 0.90 (95% CI, 0.87-0.93), which was significantly higher than for the ED probability alone (P=0.003). An algorithm to rule out cardiac syncope combining an MRproANP level of < 77 pmol/L and an ED probability of < 20% had a sensitivity and a negative predictive value of 99%. Conclusions--The use of MRproANP significantly improves the early detection of cardiac syncope among unselected patients presenting to the ED with syncope
