Aim and objectivesTo determine whether the virtual reality as a distracting intervention could reduce pain and fear in school‐age children receiving intravenous injections at an emergency department.BackgroundAn intravenous injection is the most common invasive procedure that paediatric patients encounter in emergency department. School‐age children seldom show their fear or discomfort during the procedure which may be ignored.DesignA randomised controlled trial was conducted from December 2017–May 2018 and performed according to the CONSORT guidelines.MethodsOne hundred and thirty‐six children aged 7–12 years were randomly allocated to receive either a routine intravenous injection procedure or one with an immersive virtual reality experience. Children were asked to rate their pain and fear along with their caregivers and nurses on the Wong–Baker FACES Pain Rating Scale and Children's Fear Scale, respectively. The time required for successful intravenous insertion was also assessed in the emergency department. Clinical trial registration was done (ClinicalTrials.gov.: NCT04081935).ResultsPain and fear scores were significantly lower in the virtual reality group, as were the children's ratings as perceived by their caregivers and nurses. The children's ratings of pain and fear were positively correlated with the caregivers’ ratings and the nurses' ratings as well. The time required for successful intravenous insertion was significantly lower in the virtual reality group.ConclusionVisual reality intervention can effectively reduce the pain and fear during intravenous procedure in school‐age children in emergency department.Relevance to clinical practiceThe results of this study indicate the feasible clinical value of virtual reality interventions during the administration of intravenous injections in school‐age children in emergency departments.

Landslides are typically triggered by earthquakes or rainfall occasionally a rainfall event followed by an earthquake or vice versa. Yet, most of the works presented in the past decade have been largely focused at the single event-susceptibility model. Such type of modeling is found insufficient in places where the triggering mechanism involves both factors such as one found in the Chuetsu region, Japan. Generally, a single event model provides only limited enlightenment of landslide spatial distribution and thus understate the potential combination-effect interrelation of earthquakes- and rainfall-triggered landslides. This study explores the both-effect of landslides triggered by Chuetsu-Niigata earthquake followed by a heavy rainfall event through examining multiple traditional statistical models and data mining for understanding the coupling effects. This paper aims to compare the abilities of the statistical probabilistic likelihood-frequency ratio (PLFR) model, information value (InV) method, certainty factors (CF), artificial neural network (ANN) and ensemble support vector machine (SVM) for the landslide susceptibility mapping (LSM) using high-resolution-light detection and ranging digital elevation model (LiDAR DEM). Firstly, the landslide inventory map including 8459 landslide polygons was compiled from multiple aerial photographs and satellite imageries. These datasets were then randomly split into two parts: 70% landslide polygons (5921) for training model and the remaining polygons for validation (2538). Next, seven causative factors were classified into three categories namely topographic factors, hydrological factors and geological factors. We then identified the associations between landslide occurrence and causative factors to produce LSM. Finally, the accuracies of five models were validated by the area under curves (AUC) method. The AUC values of five models vary from 0.77 to 0.87. Regarding the capability of performance, the proposed SVM is promising for constructing the regional landslide-prone potential areas using both types of landslides. Additionally, the result of our LSM can be applied for similar areas which have been experiencing both rainfall-earthquake landslides.

This article conducts a meta-analysis to determine the effect of perceived risk on intention to purchase in e-commerce settings. The literature generally favors the negative relationship between the two variables; however, some studies have found this relationship to be not significant or even positive. Thirty-five studies were examined, representing 39 overall samples across multiple contexts with a total sample size of 13779 and overall weighted effect size (Pearson's r) for all studies of −0.362 (95% CI: −.432, −.286), a significant medium effect, with a stronger effect in B2C than B2B contexts. Major IS journals rarely report non-significant results and reflect publication bias, posing a problem for a comprehensive meta-analysis. Due to the reluctance to report or accept, studies showing non-significant results represent a significant challenge for IS research. Our aim is to encourage more meta-analysis in IS literature and utilize this methodology to analyze previously held theories.

AimTo investigate the protective behaviours of longer near work distance, discontinuing near work and more time outdoors in recess from parent self-report in the myopia prevalence and progression among myopic children aged 9–11 years.MethodsMyopia Investigation study in Taipei is a longitudinal population-based study that enrolled elementary school students in Taipei. We provided vision and refraction examination every 6 months. Spherical equivalent (SE) of cycloplegic refraction ≤−0.50 Diopter (D) is defined as myopia. Total 10 743 (70.4%) students completed 2-year refraction data and questionnaire. The myopia prevalence and progression (difference of SE) in baseline, 6, 12, 18 and 24 months were compared by generalised estimating equations.ResultsChildren with persistent protective behaviour had significant lower prevalence of myopia. The protective impact was statistically significant from 6 to 24 months. In 2 years follow-up, risk ratio after adjusting the background variables and the other two behaviours in near work distance, near work time and outdoor time were 0.71, 0.89 and 0.77. In SE analysis, after adjusting the other two behaviours, near work distance >30 cm (−0.7 vs −1.04 D; p<0.001), discontinuing near work every 30 min (−0.77 vs −0.96 D, p=0.005) and more time outdoors in recess from parent self-report (−0.75 vs −0.98 D; p=0.012) revealed protective impacts on diminishing myopia progression from 6 to 24 months.ConclusionIn myopic children aged around 10 years in Taipei, longer distance in near work, discontinuing near work every 30 min and more outdoor time from parent self-report are protective behaviours in myopia prevalence and progression in 6–24 months.

Purpose The purpose of this study is to develop and examine an integrated mediating model that contains relationship benefits as the relationship antecedents; trust, relationship commitment and gratitude as mediators; and repurchase intention as the relationship consequence in a service business context. Design/methodology/approach The study recruited 253 respondents to test the proposed model. A partial-least-square-based structural equation modeling was adopted to evaluate the measurement of research constructs and test the research hypotheses that underpinned a proposed conceptual model. Findings The results show that confidence benefits increase trust more than social and special treatment benefits; social benefits have the most influence on relationship commitment; and special treatment benefits most greatly enhance feelings of gratitude. Thus, depending on the improvement objectives, marketers can accordingly choose the proper relationship benefits as a primary approach. Furthermore, both the direct and indirect effects of confidence benefits and social benefits on repurchase intention were significant. Research limitations/implications The main limitation of this study is that all research variables were measured at a static point rather than as they were developing. Ignorance of the temporal sequence may incur the concern of possible spurious causal relationship inferences. Practical implications The study’s findings offer several important implications for service providers, which, in this study, were separated into high (e.g. such as hairdressing, beauty and massage) and low personal contact service groups (e.g. telecommunications and equipment maintenance). First, social benefits are more effective at increasing gratitude in the low personal contact service group, and at boosting trust in the high-contact group. Second, special treatment benefits increase gratitude much more in the high-contact group than in the low personal contact group. Third, gratitude has a much stronger effect on repurchase intention in the high personal contact group than in the low-contact group. Originality/value The interactions among relationship benefits, mediators (i.e. trust and relationship commitment) and outcomes remain unclear. Although the importance of gratitude as a mediator in relationship marketing (RM) has been shown, little research has examined how relational benefits influence repurchase intention through the combined mediating effects of commitment, trust and gratitude. Therefore, this study advances RM theory by examining the degree of additional explaining power that gratitude contributes to the commitment–trust model. The study also makes a practical contribution by building a research model to understand the nature of mediating roles played by relationship commitment, trust and gratitude in the service industry.
