Vision (im)possible? The effects of in-store signage on customers’ visual attention

We used two eye-tracking field experiments to investigate the extent to which in-store signage is used during navigation and decision making, and how the viewing of signage influences customers’ visual attention and choice behavior. One hundred and seventy-five customers at a grocery store were exposed to signage stimuli while carrying out predefined shopping tasks. Experiment 1 shows that attention toward signage is affected by customers’ levels of store familiarity and in-store search stage (navigation vs. decision making). Experiment 2 demonstrates that signage has a considerable impact on the direction and magnitude of customers’ visual attention during decision making.     

Nonparametric learning rules from bandit experiments: The eyes have it!

How do people learn? We assess, in a model-free manner, subjectsʼ belief dynamics in a two-armed bandit learning experiment. A novel feature of our approach is to supplement the choice and reward data with subjectsʼ eye movements during the experiment to pin down estimates of subjectsʼ beliefs. Estimates show that subjects are more reluctant to “update down” following unsuccessful choices, than “update up” following successful choices. The profits from following the estimated learning and decision rules are smaller (by about 25% of average earnings by subjects in this experiment) than what would be obtained from a fully-rational Bayesian learning model, but comparable to the profits from alternative non-Bayesian learning models, including reinforcement learning and a simple “win-stay” choice heuristic.     

氢氧化钙联合氯已定在年轻恒牙外伤后牙髓血运重建中的应用价值

目的探讨氢氧化钙联合氯已定在年轻恒牙外伤后血运重建中的应用价值。方法选取2017年11月至2019年4月锦州医科大学附属第二医院口腔内科接收的78例年轻恒牙外伤患者(86颗患牙)作为研究对象,通过随机分组方式分为试验组(39例,44颗患牙)与对照组(39例,42颗患牙)。对照组患儿应用氢氧化钙行根尖诱导成形术,试验组患儿应用氢氧化钙、氯已定根管封药后进行牙髓血运重建术,比较两组患儿临床效果。结果试验组患儿治疗有效率(100.00%)明显高于对照组(80.95%),差异有统计学意义(P<0.05);治疗后,试验组患儿牙齿叩痛、牙龈肿胀、瘘管、牙齿松动度评分明显低于对照组,差异有统计学意义(P<0.05)。结论对年轻恒牙外伤患儿予以氢氧化钙和氯已定联合治疗,有利于提高牙髓血运重建术效果,促进患儿牙根发育,且降低牙冠变色概率。     

Food Package Familiarity and Perceived Amount of Verbal Information: The Moderating Effect of Frugal Behavior

ABSTRACT

This paper discusses the moderating effect of frugal behavior on the relationship between food package familiarity and the perceived amount of verbal information. Two experiments were conducted on food packaging to analyze two central points: (a) the relationship between food package familiarity and the perceived amount of verbal information and (b) the moderating effect of frugal behavior on this relationship. The studies demonstrate the negative influence of food package familiarity on the perceived amount of verbal information. We demonstrate that the greater (smaller) the familiarity with food packaging is, the smaller (greater) the visual attention to the verbal information will be. Second, we show that frugal behavior moderates this behavior. Our experiment shows that a greater (smaller) tendency toward frugal behavior tends to have a positive (maintain negative) effect on the relationship between food package familiarity and the perceived amount of verbal information.     

Interpersonal violence in the United Arab Emirates

We aimed to study the anatomical distribution, severity and outcome of hospitalised interpersonal violence-related injured patients in Al-Ain, United Arab Emirates so as to give recommendations regarding the magnitude of this problem, its causes and priorities of prevention. Data were retrieved from Al-Ain Hospital Trauma Registry, which was prospectively collected over three years. There were 75 patients (males = 85.3%) having a mean age of 30 years. Eighty-one percent had blunt trauma. The estimated annual injury hospitalisation of interpersonal violence in Al-Ain city was 6.7 per 100,000 population. Females were significantly more injured by a family member (p = 0.02), at home (p = 0.005), and had more severe injuries (p = 0.003). There was a trend for children less than 18 years old to have more penetrating trauma (p = 0.06) and to be injured by a family member (p = 0.09). There was only one case of woman sexual assault and two cases of child abuse. The mean (SD) hospital stay was 7.87 (14.1) days. Less than 3% (n = 2) were admitted to the intensive care unit with no deaths. In conclusion, the majority of patients in our study had minor injuries. Nevertheless, the psychological impact may be major. This highlights the need to develop suitable mental health services in support of victims of interpersonal violence.     

两种不同手术方式治疗眼外伤继发青光眼的临床疗效

目的探讨两种不同手术方式治疗眼外伤继发青光眼的临床疗效。方法选取我院202例眼外伤继发青光眼患者,随机将患者分为A组和B组,分别采用小梁切除术和周围虹膜切除术进行治疗,术后对两组患者进行为期3个月的随访,记录每月眼压和视力的变化。结果两组患者术后眼压和视力恢复情况均较好,差异无统计学意义(P>0.05)。结论眼外伤继发青光眼病因复杂,明确致病机制,针对性采取治疗是取得疗效的重要环节,对继发青光眼病因和治疗方式的进一步研究对于改善患者眼压和视力具有重要的意义。     

Celebrity endorsement in tourism: Attention,emotional arousal and familiarity

Celebrity endorsement in tourism is utilised by global marketing practitioners to attract tourists to visit destinations. Despite this, studies are yet to assess the efficacy of two specific types of celebrity endorsement, a celebrity from the host country (host celebrity) vs. a celebrity from the country-of-origin (origin celebrity). Utilising the match-up hypothesis, this research applied a quasi-experimental design, consisting of a mixed method approach, which combined eye-tracking and self-report data. Convergent results across three studies demonstrate that an origin celebrity elicits a higher intention to visit, mediated by the emotional arousal evoked from the endorsement. Eye-tracking analysis demonstrated that an origin celebrity elicits a higher degree of visual attention and emotional arousal when the advertised scenery is familiar. However, this promotion effect disappears in unfamiliar scenery. This research contributes to an evolving debate on celebrity endorsement in tourism, revealing the psychological and physiological mechanisms underpinning the effectiveness of destination marketing campaigns.     

Climate Change and Preparations for the Tide of Traumatic Stress: Implications for Asia-Pacific Human Resources

Although attention to the business risks posed by natural disasters fueled by climate change has grown, the toll that disasters have on human resources in the form of traumatic stress is comparatively neglected. It is common for more than 20% of people exposed to natural disasters to develop traumatic stress disorders that can last for years. In the workplace, traumatic stress hurts attendance, the quantity and quality of output, and relationships. Fortunately, businesses can promote employee resilience and recovery. Given the Asia-Pacific region’s high risk of natural disasters, businesses operating there should include employees’ traumatic stress in their disaster preparedness.     

Trauma epidemiology in Puerto Rico: in-hospital morbidity and mortality from 2002 to 2011

This study aimed to describe the distribution of injury mechanisms and to assess the impact of those mechanisms on the morbidity and mortality of trauma. All patients admitted to Puerto Rico Trauma Hospital (2002–2011) for road-traffic collisions (RTCs, 5,371), gunshot wounds (GSWs, 2,946), falls (2,319), pedestrian accidents (1,652), and stab wounds (SWs, 1,073) were selected. Gunshot victims were 1.19 (95%CI: 1.07–1.33) times as likely as road-traffic victims to have an ISS ≥25. Pedestrians were 1.76 (95%CI: 1.49–2.09) times more likely to have a GCS ≤8 than road-traffic victims were. The risk of dying was 2.64 (95%CI: 2.20–3.16) times higher for gunshot victims and 1.51 (95%CI: 1.23–1.86) times higher for pedestrians compared to patients who had had RTCs. Gunshot victims and pedestrians had the worst clinical outcomes. Accordingly, these patients should receive the most aggressive clinical management. Furthermore, it is imperative to develop public health campaigns on trauma prevention.     

Going Through Hell: Increased Work Effort in the Aftermath of Terrorism in Norway*

I analyze how sickness‐absence behavior in Norwegian municipalities was affected by exposure to the terrorist attack in Norway in 2011. The main finding is that in municipalities from which a resident was killed in the attack, sickness absence declined by 4 percent compared with municipalities without victims. The effect is precise, stable, and persistent. The results do not seem to be driven by changing labor market composition. The effect is found also in neighboring municipalities and is larger for people close to the age of the victims.
