    Get PDF
    The role and the existing and potential use of online social networking as a relationship marketing (RM) tool is evaluated in the context of luxury hotels. Semi-structured interviews were conducted with the persons responsible for the management of social networking in 10 luxury hotels. Constant comparative analysis, applied within a codebook framework, revealed online social networks (OSNs) provided RM opportunities and increased business value. It is acknowledged that the full potential of OSNs has yet to be realised in terms of hotel marketing. Opportunities for extending the utilisation of OSNs are identified alongside recommendations for hotel marketing practitioners with regard to addressing consumers' needs, and areas for further research are outlined. © 2013 Copyright 2013 Westburn Publishers Ltd

    Get PDF
    Purpose – This paper aims to discuss stakeholders’ understanding of sustainable tourism development and their experiences regarding the contribution of these movements to sustainable tourism development. The contribution of the Slow Food and Cittaslow Movements to the success of a tourism destination is evaluated by determining local stakeholders’ perceptions of the meaning of these terms and views on their benefits. Design/methodology/approach – A case study approach used semi-structured interviews to collect data from 11 purposively sampled local stakeholders. The interview questions spanned knowledge, membership and perceived benefits of the Slow Food and Cittaslow Movements and the contribution of these Movements to sustainable tourism development. The data were analysed using framework analysis. Findings – Varying levels of familiarity with the Slow Food and Cittaslow Movements were evident. Clear economic and personal benefits from membership were acknowledged. It was confirmed that the Slow Food and Cittaslow Movements have contributed to sustainable tourism development and that public–private partnership is key to its success. Research limitations/implications – The specific research context and limited purposive sample suggest great caution in any generalisation of the results. Practical implications – Close and continued involvement of stakeholders plus membership of the Slow Food and Cittaslow Movements can contribute strongly to promoting sustainable tourism development in rural areas. Social implications – It is recognised that the Slow Food and Cittaslow Movements make a substantial contribution to local economies and add value to sustainable practices. Originality/value – Involving local stakeholders in public–private partnerships can contribute to the success of rural tourism destinations when the Slow Food and Cittaslow Movements are considered as alternative approaches to sustainable tourism development

    The role of stakeholder collaboration in culture-led urban regeneration: A case study of the Gwangju project, Korea

    The preliminary stages of a large scale culture-led urban regeneration project initiated by the Korean government in Gwangju were studied. Stakeholders’ perceptions of culture’s contribution to urban regeneration and their views on collaborative partnerships were explored. Qualitative data were gathered via semi-structured interviews from 19 purposively selected stakeholders. This case study determined public–private cooperation in regenerating Gwangju could, simultaneously, generate positive socio-cultural and economic impacts in society. However, stakeholders lacked opportunities for active participation. Hence, closer working relationships between central–municipal government and public–private/voluntary sectors were recommended. The case confirmed that long-term implementation of such projects needs to be anticipated and based on longitudinal and structured strategic planning to promote successful partnership collaborations amongst central/municipal governments, local communities and residents. This paper contributed to the knowledge gap in the area of stakeholder collaboration in building tourism/cultural systems by examining the micro-level interactions amongst stakeholders

    Heavy Flavour Production at Tevatron and Parton Shower Effects

    We present hadron-level predictions from the Monte Carlo generator Cascade and numerical calculations of charm and beauty production at the Fermilab Tevatron within the framework of the kTk_T-factorization QCD approach. Our consideration is based on the CCFM-evolved unintegrated gluon densities in a proton. The performed analysis covers the total and differential cross sections of open charm and beauty quarks, BB and DD mesons (or rather muons from their semileptonic decays) and the total and differential cross sections of bbˉb \bar b di-jet hadroproduction. We study the theoretical uncertainties of our calculations and investigate the effects coming from parton showers in initial and final states. Our predictions are compared with the recent experimental data taken by the D0 and CDF collaborations. Special attention is put on the specific angular correlations between the final-state particles. We demonstrate that the final state parton shower plays a crucial role in the description of such observables. The decorrelated part of angular separations can be fully described, if the process gggggg^*\rightarrow gg is included.Comment: Fig 8,9 10 replaced, small corrections in text A discussion of the delta phi results is adde

    Anticarbamylated protein antibodies are associated with long-term disability and increased disease activity in patients with early inflammatory arthritis:Results from the Norfolk Arthritis Register

    Objectives: Anticarbamylated protein (anti-CarP) antibodies are a novel family of autoantibodies recently identified in patients with inflammatory arthritis. The aim of this study was to investigate their association with long-term outcomes of disability and disease activity over 20 years’ follow-up in a cohort of patients with inflammatory polyarthritis (IP).  Methods: Norfolk Arthritis Register recruited adults with recent-onset swelling of ≥2 joints for ≥4 weeks from 1990 to 2009. At baseline, Health Assessment Questionnaire (HAQ) and 28 joint disease activity scores (DAS28) were obtained, and C reactive protein, rheumatoid factor (RF), anticitrullinated protein antibodies (ACPA) and anti-CarP antibodies were measured. Further HAQ scores and DAS28 were obtained at regular intervals over 20 years. Generalised estimating equations were used to test the association between anti-CarP antibody status and longitudinal HAQ and DAS28 scores; adjusting for age, gender, smoking status, year of inclusion and ACPA status. Analyses were repeated in subgroups stratified by ACPA status. The relative association of RF, ACPA and anti-CarP antibodies with HAQ and DAS28 scores was investigated using a random effects model.  Results: 1995 patients were included; 1310 (66%) were female. Anti-CarP antibodies were significantly associated with more disability and higher disease activity, HAQ multivariate β-coefficient (95% CI) 0.12 (0.02 to 0.21), and these associations remained significant in the ACPA-negative subgroups. The associations of RF, ACPA and anti-CarP antibodies were found to be additive in the random effects model.  Conclusions: Anti-CarP antibodies are associated with increased disability and higher disease activity in patients with IP. Our results suggest that measurement of anti-CarP antibodies may be useful in identifying ACPA-negative patients with worse long-term outcomes. Further, anti-CarP antibody status provided additional information about RF and ACPA

    Value of tissue harmonic imaging (THI) and contrast harmonic imaging (CHI) in detection and characterisation of breast tumours

    The purpose of this study was to investigate the extent to which tissue harmonic imaging (THI), speckle reduction imaging (SRI), spatial compounding (SC) and contrast can improve detection and differentiation of breast tumours. We examined 38 patients (14 benign, 24 malignant tumours) with different combinations of THI, SRI and SC. The effect on delineation, margin, tissue differentiation and posttumoral phenomena was evaluated with a three-point score. Additionally, 1oo not palpable tumours (diameters: 4–15 mm) were examined by contrast harmonic imaging (CHI) with power Doppler. After bolus injection (0.5 ml Optison), vascularisation and enhancement were observed for 20 min. The best combination for detection of margin, infiltration, echo pattern and posterior lesion boundary was the combination of SRI level 2 with SC low. THI was helpful for lesions OF more than 1 cm depth. In native Power Doppler, vessels were found in 54 of 100 lesions. Within 5 min after contrast medium (CM) injection, marginal and penetrating vessels increased in benign and malignant tumours and central vessels mostly in carcinomas (p<0.05). A diffuse CM accumulation was observed up to 20 min after injection in malignant tumours only (p<0.05). THI, SRI and SC improved delineation and tissue differentiation. Second-generation contrast agent allowed detection of tumour vascularisation with prolonged enhancement

    TLR7 ligation augments hematopoiesis in Rps14 (uS11) deficiency via paradoxical suppression of inflammatory signaling

    Myelodysplastic syndrome (MDS) is a hematological malignancy characterized by blood cytopenias and predisposition to acute myeloid leukemia (AML). Therapies for MDS are lacking, particularly those that have an impact in the early stages of disease. We developed a model of MDS in zebrafish with knockout of Rps14, the primary mediator of the anemia associated with del(5q) MDS. These mutant animals display dose- and age-dependent abnormalities in hematopoiesis, culminating in bone marrow failure with dysplastic features. We used Rps14 knockdown to undertake an in vivo small-molecule screening, to identify compounds that ameliorate the MDS phenotype, and we identified imiquimod, an agonist of Toll-like receptor-7 (TLR7) and TLR8. Imiquimod alleviates anemia by promoting hematopoietic stem and progenitor cell expansion and erythroid differentiation, the mechanism of which is dependent on TLR7 ligation and Myd88. TLR7 activation in this setting paradoxically promoted an anti-inflammatory gene signature, indicating cross talk via TLR7 between proinflammatory pathways endogenous to Rps14 loss and the NF-κB pathway. Finally, in highly purified human bone marrow samples from anemic patients, imiquimod led to an increase in erythroid output from myeloerythroid progenitors and common myeloid progenitors. Our findings have both specific implications for the development of targeted therapeutics for del(5q) MDS and wider significance identifying a potential role for TLR7 ligation in modifying anemia

    Interleukin-1 polymorphisms associated with increased risk of gastric cancer

    Get PDF
    Helicobacter pylori infection is associated with a variety of clinical outcomes including gastric cancer and duodenal ulcer disease. The reasons for this variation are not clear, but the gastric physiological response is influenced by the severity and anatomical distribution of gastritis induced by H. pylori. Thus, individuals with gastritis predominantly localized to the antrum retain normal (or even high) acid secretion, whereas individuals with extensive corpus gastritis develop hypochlorhydria and gastric atrophy, which are presumptive precursors of gastric cancer. Here we report that interleukin-1 gene cluster polymorphisms suspected of enhancing production of interleukin-1-beta are associated with an increased risk of both hypochlorhydria induced by H. pylori and gastric cancer. Two of these polymorphism are in near-complete linkage disequilibrium and one is a TATA-box polymorphism that markedly affects DNA-protein interactions in vitro. The association with disease may be explained by the biological properties of interleukin-1-beta, which is an important pro-inflammatory cytokine and a powerful inhibitor of gastric acid secretion. Host genetic factors that affect interleukin-1-beta may determine why some individuals infected with H. pylori develop gastric cancer while others do no
