Attention Limitations in the Detection and Identification of Alarms in Close Temporal Proximity

Objective The aim of this study was to establish the effects of simultaneous and asynchronous masking on the detection and identification of visual and auditory alarms in close temporal proximity. Background In complex and highly coupled systems, malfunctions can trigger numerous alarms within a short period of time. During such alarm floods, operators may fail to detect and identify alarms due to asynchronous and simultaneous masking. To date, the effects of masking on detection and identification have been studied almost exclusively for two alarms during single-task performance. This research examines 1) how masking affects alarm detection and identification in multitask environments and 2) whether those effects increase as a function of the number of alarms. Method Two experiments were conducted using a simulation of a drone-based package delivery service. Participants were required to ensure package delivery and respond to visual and auditory alarms associated with eight drones. The alarms were presented at various stimulus onset asynchronies (SOAs). The dependent measures included alarm detection rate, identification accuracy, and response time. Results Masking was observed intramodally and cross-modally for visual and auditory alarms. The SOAs at which asynchronous masking occurred were longer than reported in basic research on masking. The effects of asynchronous and, even more so, simultaneous masking became stronger as the number of alarms increased. Conclusion Masking can lead to breakdowns in the detection and identification of alarms in close temporal proximity in complex data-rich domains. Application The findings from this research provide guidance for the design of alarm systems.

An Empirical Investigation on the Influence of Temporal Distance on the Acceptance of Innovations - Using the Example of Urban Air Mobility

Upon reviewing different approaches to explain the acceptance of innovations, it becomes apparent that the temporal proximity or distance of innovations, the possible effects of which could be neglected, are not considered sufficiently. The question is whether the influence on the acceptance can be observed by high or low temporal distance. This assumption is motivated by the implications of the Construal Level Theory, which suggests such an influence of temporal proximity or distance of an event on the evaluation. The concept of Urban Air Mobility was used as an example of application. To test this assumption, the participants (N = 369) of an online survey were confronted with a temporally close or distant condition and asked to complete a questionnaire designed on the basis of UTAUT2 and other measurement aspects. The results showed that the different conditions had an influence on the time estimation of the participants. Furthermore a significant influence of the moderating effect of the time distance could be determined for the factor safety concerns.

The War That Never Happened

This article examines Mark Z. Danielewski’s House of Leaves (2000), a gothic novel that augments its postmodernist credentials by preemptively imagining and representing the theoretical gaze that would otherwise have been directed on itself. The article suggests that despite the novel’s intense performance of self-reflexivity, it demonstrates a traumatic suppression of its own immediate historical conditions, particularly its temporal proximity to the events of the First Gulf War. This article thus reads the text’s telling silences and its thematization of uncanny spatial violations as indexing a minimally acknowledged guilt over the war in Iraq. The novel’s slippages in self-awareness not only point to an avoidance of its own scotomized history but also foreground the shifting boundaries and dispersed locations of textual self-consciousness.

Infections in temporal proximity to HPV vaccination and adverse effects following vaccination in Denmark: A nationwide register-based cohort study and case-crossover analysis

Background Public trust in the human papilloma virus (HPV) vaccination programme has been challenged by reports of potential severe adverse effects. The reported adverse symptoms were heterogeneous and overlapping with those characterised as chronic fatigue syndrome (CFS) and have been described as CFS-like symptoms. Evidence suggests that CFS is often precipitated by an infection. The aim of the study was to examine if an infection in temporal proximity to HPV vaccination is a risk factor for suspected adverse effects following HPV vaccination. Methods and findings The study was a nationwide register-based cohort study and case-crossover analysis. The study population consisted of all HPV vaccinated females living in Denmark, born between 1974 and 2006, and vaccinated between January 1, 2006 and December 31, 2017. The exposure was any infection in the period ± 1 month around time of first HPV vaccination and was defined as (1) hospital-treated infection; (2) redemption of anti-infective medication; or (3) having a rapid streptococcal test done at the general practitioner. The outcome was referral to a specialised hospital setting (5 national HPV centres opened June 1, 2015) due to suspected adverse effects following HPV vaccination. Multivariable logistic regression was used to estimate the association between infection and later HPV centre referral. The participants were 600,400 HPV-vaccinated females aged 11 to 44 years. Of these, 48,361 (9.7%) females had a hospital-treated infection, redeemed anti-infective medication, or had a rapid streptococcal test ± 1 month around time of first HPV vaccination. A total of 1,755 (0.3%) females were referred to an HPV centre. Having a hospital-treated infection in temporal proximity to vaccination was associated with significantly elevated risk of later referral to an HPV centre (odds ratio (OR) 2.75, 95% confidence interval (CI) 1.72 to 4.40; P < 0.001). Increased risk was also observed among females who redeemed anti-infective medication (OR 1.56, 95% CI 1.33 to 1.83; P < 0.001) or had a rapid streptococcal test (OR 1.45, 95% CI 1.10 to 1.93; P = 0.010). Results from a case-crossover analysis, which was performed to adjust for potential unmeasured confounding, supported the findings. A key limitation of the study is that the HPV centres did not open until June 1, 2015, which may have led to an underestimation of the risk of suspected adverse effects, but stratified analyses by year of vaccination yielded similar results. Conclusions Treated infection in temporal proximity to HPV vaccination is associated with increased risk for later referral with suspected adverse vaccine effects. Thus, the infection could potentially be a trigger of the CFS-like symptoms in a subset of the referred females. To our knowledge, the study is the first to investigate the role of infection in the development of suspected adverse effects after HPV vaccination and replication of these findings are needed in other studies.

Immigration, Race, and Nation in the UK: The Politics of Belonging on Twitter

At a time of rising right-wing populism, the heightened political salience of immigration as an issue is linked to conceptions of ‘the national’. In this article, we analyse tweets from non-elites, defined as isolated users with low network influence, engaged in a ‘conversation’ about migration on Twitter. We investigate the values embedded in these attitudes, and what these tell us about constructions and contestations of the symbolic boundaries of the nation among ordinary people. Our corpus includes tweets posted in temporal proximity to the lifting of transitional controls on Romanian and Bulgarian migrants in the UK (1 October 2013 to 1 March 2014). Thematic analysis reveals a cohesive set of anti-immigrant or anti-immigration sentiments linked to UKIP and that express an exclusionary nationalism based on assumptions about race, ‘whiteness’ and entitlement. Also evident is a counter-narrative of pro-immigration sentiments that draw on multiple and sometimes contradictory values. Some of these values contest racialised understandings of the nation but do not coalesce in ways to disrupt the dominance of right-wing anti-immigrant sentiments on Twitter. Our findings demonstrate the importance of investigating values embedded in both anti and pro-immigration attitudes among non-elites and what these values indicate about the possibilities of re-framing migration debates among non-elites in ways that construct more inclusive symbolic national boundaries. In addition, in using the networked properties of Twitter engagement to identify non-elite users, we make a methodological contribution to scholarship on immigration attitudes.

Multisystem inflammatory syndrome in children (MIS-C) occurring in temporal proximity between siblings

We report a pair of siblings who developed multisystem inflammatory syndrome in children (MIS-C) in close temporal proximity after recent exposure to SARS-CoV-2. Both siblings presented with Kawasaki disease-like features and haemodynamic instability, with the onset of symptoms within 6 days of each other. Remarkably, one of the siblings was the elder of a pair of monozygotic twins. The younger monozygotic twin, however, did not develop MIS-C.

A Descriptive Analysis of the Temporal and Geographical Proximities Seen Within UK Series of Sex Offenses

Previous studies of the geographical and temporal features of serial sex offenses are limited by small samples and/or geographical areas, and are dated. We address a significant gap in the literature by investigating the temporal and geographical proximity of the crimes of 402 serial stranger sex offenders in the UK. Periods of incarceration were extracted from calculations of temporal proximity giving a more accurate picture of series duration and time elapsed between offenses from the same series. A notable minority of serial stranger sex offenders commit their offenses within very close geographic proximity and the same was found for temporal proximity. There were also occurrences of series spanning large distances and many years. The implications of these findings for the use of geography and time in the behavioral linking of crimes, and what they mean for policy decisions regarding financial investment in law enforcement technology, are discussed.
