Purpose
This study aims to adopt a cognitive heuristic approach to investigate the interaction effect of a message source characteristic (reviewer expertise RE) and two message structure ...characteristics (review rating consistency RC and review valence RV) on the perceived credibility of hotel online reviews.
Design/methodology/approach
Data were collected from 242 university students and were analyzed by three-way analysis of variance through a 2 × 2 factorial experiments using a simulated hotel review page on TripAdvisor.
Findings
Results show a three-way interaction effect of RE, RC and RV on the perceived credibility of hotel online reviews. The main effects of the three factors are also determined. Higher perceived credibility scores are found for negative reviews, reviews written by experts and reviews with a consistent rating.
Research limitations/implications
This study adopts an experimental approach and is the first to investigate the three-way interactions of message source and message structure characteristics of online hotel reviews. Data were collected from students in a university in Hong Kong. Results may not be generalizable to other markets.
Practical implications
Results suggest that reviews written by experts have higher perceived credibility. Hotels should pay attention to the content of online reviews and the expertise level of reviewers. Efforts should be exerted to create positive experiences for hotel guests that motivate expert reviewers to write positive reviews. Note that negative reviews have higher perceived credibility than positive ones. Hotels should promptly address negative reviews and provide professional responses to reviewers. Platform operators of user-generated content (UGC) should create well-defined reviewer profiles that can serve as cues that communicate the different expertise of reviewers.
Originality/value
This study is the first to test the three-way interaction effect of RE, RC and RV on the perceived credibility of hotel online reviews. Results provide recommendations to hotels and UGC operators and enable them to benefit from emerging UGC usage.
People with epilepsy frequently express concern about the burden of memory problems in their everyday lives. Self-report memory questionnaires may provide valuable insight into individuals’ ...perceptions of their everyday memory performance and changes over time. Yet, despite their potential utility, the measurement properties of self-report memory questionnaires have not been evaluated in epilepsy. This systematic review aimed to provide a critical appraisal of the measurement properties of self-report memory questionnaires for adults with epilepsy. Following protocol registration (PROSPERO CRD42020210967), a systematic search of PubMed, EMBASE, Web of Science, CINAHL, and PsychInfo from database inception until 27 May 2021 was conducted. Eligible studies were published in English-language peer-reviewed journals, recruited adults with epilepsy, and reported on the development or evaluation of the measurement properties of a self-report memory questionnaire. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology was used to evaluate each study of a measurement property, and results were qualitatively synthesised. In total, 80 articles and one test manual were located containing 153 studies of measurement properties pertinent to 23 self-report memory questionnaires. Overall, no scale could be recommended outright for the evaluation of subjective memory symptoms in adults with epilepsy. This was due to the near absence of dedicated content validation studies relevant to this population and shortcomings in the methodology and scientific reporting of available studies of structural validity. Recommendations to support the advancement and psychometric validation of self-report memory questionnaires for people with epilepsy are provided.
BACKGROUND The presence of entrapped lung changes the appropriate management of malignant pleural effusion from pleurodesis to insertion of an indwelling pleural catheter. No methods currently exist ...to identify entrapped lung prior to effusion drainage. Our objectives were to develop a method to identify entrapped lung using tissue movement and deformation (strain) analysis with ultrasonography and compare it to the existing technique of pleural elastance (PEL). METHODS Prior to drainage, 81 patients with suspected malignant pleural effusion underwent thoracic ultrasound using an echocardiogram machine. Images of the atelectatic lower lobe were acquired during breath hold, allowing motion and strain related to the cardiac impulse to be analyzed using motion mode (M mode) and speckle-tracking imaging, respectively. PEL was measured during effusion drainage. The gold-standard diagnosis of entrapped lung was the consensus opinion of two interventional pulmonologists according to postdrainage imaging. Participants were randomly divided into development and validation sets. RESULTS Both total movement and strain were significantly reduced in entrapped lung. Using data from the development set, the area under the receiver-operating curves for the diagnosis of entrapped lung was 0.86 (speckle tracking), 0.79 (M mode), and 0.69 (PEL). Using respective cutoffs of 6%, 1 mm, and 19 cm H2 O on the validation set, the sensitivity/specificity was 71%/85% (speckle tracking), 50%/85% (M mode), and 40%/100% (PEL). CONCLUSIONS This novel ultrasound technique can identify entrapped lung prior to effusion drainage, which could allow appropriate choice of definitive management (pleurodesis vs indwelling catheter), reducing the number of interventions required to treat malignant pleural effusion.
Purpose
This study aims to investigate the impact of the loyalty program members’ satisfaction toward the hotel loyalty program benefits and the customer management relationship initiatives of ...individual hotels on the brand relationship quality (BRQ), i.e. their relationship quality with the hotel brand, and its outcomes. The moderating impact of membership level on the hypothesized relationships was also investigated.
Design/methodology/approach
A usable sample of 920 active members of a hotel loyalty program was obtained. Structural equation modeling with partial least squares method was used to estimate the structural relationships and to investigate the moderating effect of membership level.
Findings
Employee’s customer orientation, membership communication and hotel stay-related benefits are determinants of the loyalty program members’ BRQ. BRQ is also confirmed as a higher-order construct of three latent variables which include trust, satisfaction and commitment. Moderating effects of the membership were partially supported in this study. The strongest effect of BRQ is on members’ word of mouth followed by shares of purchase. BRQ is found to have negative relationship with members’ willingness to serve as marketing resource, but the impact was small.
Research limitations/implications
This is a cross-sectional study with a population of active loyalty program members of only one luxury hotel group. The sample size of the top-tier members is also smaller in comparison to the other two groups.
Practical implications
This study contributes to the understanding of the antecedents and consequences of BRQ and the body of knowledge about loyalty program for hotel industry.
Originality/value
This is one of the few studies investigating the effectiveness of hotel loyalty programs from the active members’ perspective and the moderating effect of membership level on the relationships among BRQ, its antecedents and its outcomes.
This study examines the motivational factors and perceived value of Hong Kong volunteer tourists. The results of a focus group and in-depth interviews reveal five main motives for travelers to ...partake in volunteer trips: cultural immersion and interaction with the local people; desire to give back and show love and concern; a shared experience with family members and an educational opportunity for children; religious involvement; and escape from everyday life. The perceived value of these volunteer travelers includes personal growth and development, relationship enhancement, and change in perspective on life. The factors influencing their future decision to participate in volunteer tourism include time, financial ability, safety and health issues, arrangements and scale of the tour, and reputation of the organizer.
Abstract The term pemphigoids includes a group of autoimmune bullous diseases characterized by subepidermal blistering. Bullous pemphigoid (BP) is not only the most common disorder within the ...pemphigoid group, but also represents the most frequent autoimmune blistering disease in general. The onset and course of BP depend on a variable interaction between predisposing and inducing factors. HLA genes are the most significant genetic predisposition factor to autoimmunity mechanisms. Many studies show an association between HLA-DQβ1*0301 and distinct clinical pemphigoid variants. Imbalance between autoreactive T helper (Th) and T regulatory cells, toll-like receptor activation, and Th17/IL-17 pathway are the three possible autoimmunity triggers underlying BP. The pathomechanism of BP hinges on an autoantibody response toward structural components of the hemidesmosome (BP180 and BP230). The binding of autoantibodies leads to complement activation, recruitment of inflammatory cells, and release of proteolytic enzymes. The inflammatory cascade also may be directly triggered by activation of Th17 cells with no intervention of autoantibodies. The intervention of inducing factors in BP can be identified in no more than 15% of patients. Facilitating factors in genetically predisposed individuals are various (drug intake, physical agents, and viral infections). Drugs may act as triggers by either modifying the immune response or altering the antigenic properties of the epidermal basement membrane. Cases of induction of BP by physical agents (eg, radiation therapy, ultraviolet radiation, thermal or electrical burns, surgical procedures, transplants) are rare, but well-documented events. A contributing role in inducing BP has been suggested for infections, in particular human herpes virus (HHV) infections (cytomegalovirus, Epstein-Barr virus, and HHV-6), but also hepatitis B and C viruses, Helicobacter pylori , and Toxoplasma gondii . Unlike pemphigus, no dietary triggers have been suspected of being involved in the induction of BP. In all patients who have a diagnosis of BP, an environmental agent as a potential cause should always be considered, because the prompt discontinuation of it might result in rapid improvement or even cure of the disease.
The literature reported higher depression rates in psoriasis patients compared to the general population. Our study aimed to verify whether variability in depression prevalence was due to using ...different diagnostic tools. We also aimed to determine whether dysfunctional coping strategies might increase the depression burden. We assessed psoriasis severity by the Psoriasis Area Severity Index (PASI) and PSOdisk. We analyzed mental alterations of 120 outpatients by Hamilton Depression and Anxiety Rating Scales (HAM-D and HAM-A), Symptom Checklist-90-Revised (SCL-90-R), plus coping strategies and quality of life by Coping Orientation to Problems Experienced (COPE) Inventory and 36-Item Short Form Health Survey (SF-36). We divided our cohort into five subgroups from minimal to severe psoriasis using the PSOdisk total score. Depression prevalence varied according to the assessment criteria for specificity, frequency, and severity. Different mood disorders other than major depression emerged when we used DSM-IV-TR criteria. Correlation analysis of the criteria we used to diagnose depression or depressed mood indicated that a dysfunctional coping strategy was highly and positively correlated only in patients of the severe subgroup. Differently, a negative correlation emerged between the SF-36 Mental Summary Component (MSC) and behavioral disengagement, thus suggesting that psychopathological distress might induce patients with a marked/severe psoriasis to adopt dysfunctional coping strategies. Dermatologists are fundamental in detecting comorbid depression, referring psoriasis patients to mental health specialists to achieve adequate treatments, and preventing suicide risk.
Abstract Pemphigus includes a group of autoimmune bullous diseases with intraepithelial lesions involving the skin and Malpighian mucous membranes. Pemphigus vulgaris (PV), the most frequent and ...representative form of the group, is a prototypical organ-specific human autoimmune disorder with a poor prognosis in the absence of medical treatment. The pathomechanism of PV hinges on autoantibodies damaging cell–cell cohesion and leading to cell–cell detachment (acantholysis) of the epidermis and Malpighian mucosae (mainly oral mucosa). A controversy exists about which subset of autoantibodies is primarily pathogenic: the desmoglein-reactive antibodies or those directed against the acetylcholine receptors of the keratinocyte membrane. The onset and course of PV depend on a variable interaction between predisposing and inducing factors. Genetic predisposition has a complex polygenic basis, involving multiple genetic loci; however, the genetic background alone (“the soil”), although essential, is not by itself sufficient to initiate the autoimmune mechanism, as proven by the reports of PV in only one of two monozygotic twins and in only two of three siblings with an identical PV-prone haplotype. The intervention of inducing or triggering environmental factors (“the seed”) seems to be crucial to set off the disease. The precipitating factors are many and various, most of them directly originating from the environment (eg, drug intake, viral infections, physical agents, contact allergens, diet), others being endogenous (eg, emotional stress, hormonal disorders) but somehow linked with the subject’s lifestyle. As to certain drugs, their potential of provoking acantholysis may be implemented by their interfering with the keratinocyte membrane biochemistry (biochemical acantholysis) and/or with the immune balance (immunologic acantholysis). Viral infections, especially the herpetic ones, may trigger the outbreak of PV or simply complicate its clinical course. The precipitating effect might be due to interferons and other cytokines released by the host as a consequence of the viral attack, which overactivate the immune response. Inductions of PV by physical agents (ultraviolet or ionizing radiation, thermal or electrical burns, surgery and cosmetic procedures), contact allergens (in particular, organophosphate pesticides), dietary factors (eg, garlic, leek, onion, black pepper, red chili pepper, red wine, tea), and emotional stress are rare, but well-documented events. The possible intervention of the environment in the outbreak of PV has been overlooked in the past, but nowadays clinicians perceive it more frequently. The assumption that genetic factors alone are not sufficient to cause the outbreak of the disease, inevitably instills the idea that PV may not occur spontaneously, but always results from an interaction between an individual predisposing genetic background and environmental precipitating factors, often concealed or apparently harmless.
Studies on the relationship between customers' experiences in participating in corporate social responsibility (CSR) activities of a company (CSRE) and brand relationship quality (BRQ) are scarce. A ...survey was conducted with guests of two resort hotels in Asia, who have participated in these hotels' CSR activities during their stays. Partial least square structural equation modeling was used for the analysis. Results suggested that CSRE had a significant effect on BRQ, whereas BRQ had a significant effect on LY and FE. Insights for hotel managers into developing a strong customer brand relationship by engaging customers with appropriate and relevant CSR activities.
Abstract
Aims
Dynamic left ventricular (LV) outflow tract obstruction (LVOTO) is associated with symptoms and increased risk of developing heart failure in hypertrophic cardiomyopathy (HCM). The ...association of LVOTO and LV twist mechanics has not been well studied in HCM. The aim of the study was to compare the pattern of LV twist in patients with HCM associated with asymmetrical septal hypertrophy with and without LVOTO.
Methods and results
Echocardiography (including speckle tracking) was performed in 212 patients with HCM, divided according to the absence (n = 130) or presence (n = 82) of LVOTO (defined as peak pressure gradient ≥30 mmHg either at rest and/or with Valsalva manoeuvre). Patients with LVOTO were older, had smaller LV dimensions, a higher LV ejection fraction (LVEF), a longer anterior mitral valve leaflet length, and a higher early transmitral pulsed wave to septal tissue Doppler velocity ratio (E/E′). A univariate analysis showed that peak twist was significantly higher in patients with LVOTO compared with patients without LVOTO (19.7 ± 7.3 vs. 15.7 ± 6.0, P = 0.00015). Peak twist was similarly enhanced in patients with LVOTO, manifesting only during Valsalva (19.2 ± 5.6, P = 0.007) and patients with resting LVOTO (19.9 ± 8.0, P = 0.00004) compared with patients without LVOTO (15.7 ± 6.0). A stepwise forward logistic regression analysis showed that LVEF, LV end-systolic dimension indexed to body surface area, anterior mitral valve leaflet length, E/E′, and peak twist were all independently associated with LVOTO.
Conclusion
This study demonstrates that increased peak LV twist is independently associated with LVOTO in patients with HCM. Peak twist was similarly exaggerated in patients with only latent LVOTO, suggesting that it may play a contributory role to LVOTO in HCM.
