Background: The lower Saint Lawrence river region (LSLRR), in Quebec, has a 10-fold higher incidence of Q fever compared to the provincial rate. This study aimed to review clinical cases and the Q fever risk exposure in this region.
Methods: Data were retrieved from microbiology laboratory, medical records from Rimouski Regional Hospital and Public Health reports between 1991 and 2018. They were analyzed with Epi Info 7.2.2.6. Patients with confirmed acute, probable acute, and chronic Q fever were classified using standard case definitions and mapped according to the postal code, to assess the correlation between cases and sheep distribution.
Results: Out of 295 cases, 258 were included (241 confirmed acute, seven probable acute, 10 chronic). Median age was 49 years, 76% were male. For acute cases, the prominent symptoms were fever (99%), headache (83%), chills (80%), sweating (72%), myalgia (69%), and fatigue (67%). Clinical presentation was mostly febrile syndrome with mild hepatitis (84%). A seasonal peak was observed from May to July (56% of acute cases). Most cases (56%) occurred within the two counties where sheep production was highest. Exposure to sheep was prominent 93%, including 64% direct contact (15% shepherds, 49% sheepfold visitors), 14% indirect contact, and 15% sheepfold neighbors.
Conclusions: To our knowledge, this is one of the largest retrospective studies of Q fever cases reported in Canada. Q fever in Quebec LSLRR is associated mainly with sheep exposure. Fever and hepatitis were the most common manifestations. Preventive measures should be considered in this region to protect sheepfold workers, visitors, and their neighbors.
背景:魁北克省圣劳伦斯河下游地区(LSLRR)的Q热发病率比全省高10倍。本研究旨在回顾该地区的临床病例和Q热风险暴露情况。方法:数据来源于微生物实验室、Rimouski地区医院1991 - 2018年的医疗记录和公共卫生报告。使用Epi Info 7.2.2.6进行分析。使用标准病例定义对确诊的急性、可能急性和慢性Q热患者进行分类，并根据邮政编码绘制地图，以评估病例与绵羊分布之间的相关性。结果:共纳入295例病例258例(确诊急性241例，疑似急性7例，慢性10例)。中位年龄49岁，76%为男性。急性病例的主要症状为发热(99%)、头痛(83%)、发冷(80%)、出汗(72%)、肌痛(69%)和疲劳(67%)。临床表现多为发热综合征伴轻度肝炎(84%)。5月至7月为季节性高峰(56%的急性病例)。大多数病例(56%)发生在羊产量最高的两个县。与羊的接触占93%，其中直接接触占64%(牧羊人占15%，羊圈游客占49%)，间接接触占14%，羊圈邻居占15%。结论:据我们所知，这是加拿大报道的Q热病例中最大的回顾性研究之一。魁北克LSLRR的Q热主要与绵羊接触有关。发热和肝炎是最常见的表现。该地区应考虑采取预防措施，保护羊圈工作人员、访客及其邻居。

ABSTRACTFrom oral histories to mnemonic devices, humans have an excellent ability to remember object sequences and their relationships inside of narratives. In pedestrian wayfinding, remembering landmarks and their relationships is considered key to learning routes. This research explores whether augmenting verbal route instructions with a narrative increases the memorability of a route. Narrative theory is applied as a framework to develop narrative-based navigation instructions, which were tested in a field study (N = 18). After learning a route, participants recalled the route verbally, completed a photo-based landmark sequencing task and discussed their answers. One week later, a route recognition task and a second photo-based landmark sequencing task was completed online. Results show few significant differences between the two groups when compared quantitatively. However, during interviews, the narrative group repeatedly cited the narrative when remembering the route. The results suggest that incorporating narratives into route directions can be further explored, and that some novel direction types may not be well-measured using quantitative methods. This research confirms the prowess of landmark-based instructions to facilitate route memory, contributes to the growing body of work augmenting landmark-based route directions with detailed information, and further encourages designers to consider alternate route communication methods.KEYWORDS: Narrativepedestrian wayfindingroute memorabilityfield study Disclosure statementNo potential conflict of interest was reported by the authors.Notes1. A weak causal relationship might be said to exist: turning onto ‘Bridge street’ might be impossible without first crossing the bridge, for example, but this seems a stretch. Additionally, the user could be considered a character, but there is no guarantee of transformation, nor is navigating a non-habitual event.2. Modelling the meaning of museum stories. Remembering routes is affected by primacy and recency effects, two phenomena found in the recall sequential lists (Hilton, Wiener, and Johnson Citation2021). Items at the beginning and end of the list are more likely to be remembered than items in the middle (Baddeley Citation1999; Reisberg Citation2010). Introducing an active delay, where the user is occupied with some other task, can reduce this effect (Reisberg Citation2010).

Well-designed, neuroadaptive mobile geographic information displays (namGIDs) could improve the lives of millions of mobile citizens of the mostly urban information society who daily need to make time critical and societally relevant decisions while navigating. What are the basic perceptual and neurocognitive processes with which individuals make movement decisions when guided by human- and context-adaptive namGIDs? How can we study this in an ecologically valid way, also outside of the highly controlled laboratory? We report first ideas and results from our unique neuroadaptive research agenda that brings us closer to answering this fundamental empirical question. We present our first implemented methodological solutions of novel ambulatory evaluation methods to study and improve Location-based System (LBS) displays, by critical examination of how perceptual, neurocognitive, psychophysiological, and display design factors might influence decision-making and spatial learning in pedestrian mobility across broad ranges of users and mobility contexts.

Location-based advertising (LBA) allows marketers to send personalised communications to customers in real-time based on their real-time location. However, customers must divulge their personal information in order to enjoy the benefits of LBA. This raises serious privacy concerns on the part of customers. Very few research studies have looked into the factors that might alleviate customers’ concerns about their privacy when utilising LBA. Therefore, this research attempts to address this research gap and examines the factors that might reduce the privacy concerns of customers towards using LBA. The research model for the study is developed using privacy calculus theory to predict the behavioural intention of the customers towards using LBA. The data of 383 respondents who have experience using LBA was evaluated using Structural Equation Modelling (SEM). The findings indicate that advertising value has a favourable influence and privacy concerns have an unfavourable influence on customers’ intentions to use LBA where advertising value plays a much more important role. Privacy self-efficacy and brand trust play an influential role in reducing privacy concerns. By contrast, privacy policy stimulates even more privacy concerns, thereby impacting the intention of the customers towards using LBA.
