- Introduction: Travel behavior research has only started to address how travel affects emotional wellbeing. The development of measurement methods is an important goal of this research.Methods: A review and assessment of methods of measuring travel-related emotional wellbeing is presented guided by a conceptual framework specifying what is measured (cognitive evaluations, emotional responses, or moods), the way it is measured (proactively, instantaneously, or retrospectively), and when it is measured (before, during, or after travel). Anticipated, current, residual and recalled moods are the objects of the measurement. Only studies of commuting or other types of daily travel are addressed.Results: We find that no research has measured anticipated moods, some research has measured current moods before, after and during travel, and most research has measured recalled moods.Conclusions: The most valid and reliable method is to measure current mood instantaneously at several points in time, before, during, and after travel. A measure of emotional wellbeing can then be obtained by objective aggregation. An approximate more feasible method is to retrospectively measure recalled moods for a given specified time period that may not only include travel. The available methods for measuring recalled moods have acceptable psychometric properties but research is needed to validate these methods by comparing the results to an objective aggregation of instantaneous measures of current mood at different points in time.

- The effects of driver sleepiness are often quantified as deteriorated driving performance, increased blink durations and high levels of subjective sleepiness. Driver sleepiness has also been associated with increasing levels of electroencephalogram (EEG) power, especially in the alpha range. The present exploratory study investigated a new measure of driver sleepiness, the EEG fixation-related lambda response. Thirty young male drivers (23.6 +/- 1.7 years old) participated in a driving simulator experiment in which they drove on rural and suburban roads in simulated daylight versus darkness during both the daytime (full sleep) and night-time (sleep deprived). The results show lower lambda responses during night driving and with longer time on task, indicating that sleep deprivation and time on task cause a general decrement in cortical responsiveness to incoming visual stimuli. Levels of subjective sleepiness and line crossings were higher under the same conditions. Furthermore, results of a linear mixed-effects model showed that low lambda responses are associated with high subjective sleepiness and more line crossings. We suggest that the fixation-related lambda response can be used to investigate driving impairment induced by sleep deprivation while driving and that, after further refinement, it may be useful as an objective measure of driver sleepiness.

- Blind persons emit sounds to detect objects by echolocation. Both perceived pitch and perceived loudness of the emitted sound change as they fuse with the reflections from nearby objects: Blind persons generally are better than sighted at echolocation, but it is unclear whether this superiority is related to detection of pitch, loudness, or both. We measured the ability of twelve blind and twenty-five sighted listeners to determine which of two sounds, 500 ms noise bursts, that had been recorded in the presence of a reflecting object in a room with reflecting walls using an artificial head. The sound pairs were original recordings differing in both pitch and loudness, or manipulated recordings with either the pitch or the loudness information removed. Observers responded using a 2AFC method with verbal feedback. For both blind and sighted listeners the performance declined more with the pitch information removed than with the loudness information removed. In addition, the blind performed clearly better than the sighted as long as the pitch information was present, but not when it was removed. Taken together, these results show that the ability to detect pitch is a main factor underlying high performance in human echolocation.

- Obtaining sustainable and inclusive societal organization is not merely a simple matter of ‘doing it’ by subscribing to some winning formula. Given that conceptual frameworks always guide our thoughts, judgments and actions (Latour, 2013; Harvey, 1996; Dennett, 1993), the ways in which we relate to concepts chosen to serve as guiding forces for future development will eventually determine its outcome. As scholarly evidence continuously suggests the concepts ‘rural’ and ‘urban’ are increasingly recognized as artificial barriers for conducting sound and integrated development endeavors in a globalized reality of interconnectedness. In line with the Sustainable Development Goals, which aim to eradicate poverty, shield the planet and safeguard prosperity for all, commitment to universal access to healthy food year round has become an important agenda point. This, however, has been exacerbated by binary thinking and separate ways of doing policy. This paper aims to share experiences from a unique project launched in the northern parts of Gothenburg, Sweden’s second largest city. While the area offers ample resources and immense opportunities for areal economies, it at the same time remains one of Gothenburg’s most segregated, with high levels of unemployment, ill health and crime. The uniqueness of the project lies not only in its way of abridging the rural-urban divide, but also by consciously deferring from the debilitating rhetoric of previous ‘immigrant policies’, and instead focusing on agricultural productivity, small-scale food producers and sustainable food strategies. Such exhortations to bridge between philosophical and material polarities, however, have not come without conceptual and practical challenges, something this paper aims to subsume and open up to debate.

Extending the theoretical grounding of mobilities research : transport psychology perspectives

- This paper reconsiders the new mobilities paradigm and its relevance for the understanding of transport systems and behaviour. It argues that the mobilities field will gain from more systematically drawing on conceptual and empirical insights from psychology to complement insights as mostly derived from sociology, geography, innovation studies, anthropology, cultural studies and continental philosophy. Focused on the car as one of the most dominant objects of individual consumption, it examines psychology epistemologies that are different from those that prevail in the mobilities literature. Transport systems shape and are shaped by social and personal identities, fears and anxieties, trauma and phobia; aggression and rebellion; and the search for community and companions. These aspects have been debated in the mobilities literature, but transport psychology investigates the more fundamental motives and conditions underlying the systems, processes and practices that shape transport behaviour. This paper discusses interrelationships and common ground between the mobilities and psychology literatures, and elaborates on the specific contributions made by social, evolutionary and clinical psychology.

Exterior Auralization of Traffic Noise within the LISTEN project
- 2011
-
Ingår i: Proceedings - 6th Forum Acusticum 2011, Aalborg, 27 June - 1 July 2011. - : European Acoustical Association. - 2221-3767. ; , s. 665-669

- In the present paper, computational auralizations of a single pass-by of a passenger car and passenger train are investigated. Auralization of future traffic noise scenarios would be a valuable tool for city planners, noise consultants and decision makers, since it would make it possible to evaluate various noise mitigation solutions already at the planning stage. The main goal of the Swedish multidisciplinary research project LISTEN has been to develop such a tool. This paper reports recent listening experiments conducted to perceptually evaluate the auralizations and subsequent improvements on computational methodologies regarding road and rail traffic noise and passenger train source models.

- Purpose--What is required of job design and production planning, if they are to result in a work group taking a self-starting approach and going beyond what is formally required of it? This paper aims to contribute to group research by testing a theoretical model of relations between job design on the one hand (captured as completeness, demand on responsibility, demand on cooperation, cognitive demand, and learning opportunities), and reflexivity and learning processes within natural work groups in industry on the other hand. Design/methodology/approach--The results are based on detailed task analyses and questionnaires from 40 work groups at the shop-floor level in manufacturing industry in Sweden. Findings--Job design and work routines show strong effects on reflexivity and learning processes. Four dimensions of job design--completeness, demand on cooperation, cognitive demand and learning opportunities--impact on reflexivity and learning processes. Job design correlates with social routines, and social routines with work routines. Practical implications--It is crucial to create a job design that puts challenging demands on the group if group processes are to be characterized by reflexivity and learning. Managers have a challenging task to provide both a space and a climate that supports reflexivity and learning. All functions affected by production planning need to be involved in job design to balance conflicts between productivity and innovation. Originality/value--Detailed task analysis is worthwhile as it captures aspects that are prerequisites for innovative groups not previously accounted for. (Contains 2 figures and 4 tables.)

Tidskriftsartikel (refereegranskat)abstract
- Driver fatigue is a contributing factor in about 20% of all fatal road crashes worldwide. Countermeasures are urgently needed and one of the most promising and currently available approaches for that are in-vehicle systems for driver fatigue detection. The main objective of this paper is to present a video-based driver sleepiness detection system set up as a two-stage model with (1) a generic deep feature extraction module combined with (2) a personalised sleepiness detection module. The approach was designed and evaluated using data from 13 drivers, collected during naturalistic driving conditions on a motorway in Sweden. Each driver performed one 90-minute driving session during daytime (low sleepiness condition) and one session during night-time (high sleepiness condition). The sleepiness detection model outputs a continuous output representing the Karolinska Sleepiness Scale (KSS) scale from 1-9 or a binary decision as alert (defined as KSS 1-6) or sleepy (defined as KSS 7-9). Continuous output modelling resulted in a mean absolute error (MAE) of 0.54 KSS units. Binary classification of alert or sleepy showed an accuracy of 92% (sensitivity = 91.7%, specificity = 92.3%, F1 score = 90.4%). Without personalisation, the corresponding accuracy was 72%, while a standard fatigue detection PERCLOS-based baseline method reached an accuracy of 68% on the same dataset. The developed real-time sleepiness detection model can be used in the management of sleepiness/fatigue by detecting precursors of severe fatigue, and ultimately reduce sleepiness-related road crashes by alerting drivers before high levels of fatigue are reached.

Tidskriftsartikel (refereegranskat)abstract
- Background: Guided Internet-based cognitive-behavioral therapy (ICBT) has been found to be effective for social anxiety disorder (SAD) by several independent research groups. However, since the extent of clinically significant change demonstrated leaves room for improvement, new treatments should be developed and investigated. A novel treatment, which has generally been found to be effective, is cognitive bias modification (CBM). This study aims to evaluate the combination of CBM and ICBT. It is intended that two groups will be compared; one group randomized to receiving ICBT and CBM towards threat cues and one group receiving ICBT and control training. We hypothesize that the group receiving ICBT plus CBM will show superior treatment outcomes.Methods/design: Participants with SAD (N = 128), will be recruited from the general population. A composite score combining the scores obtained from three social anxiety questionnaires will serve as the primary outcome measure. Secondary measures include self-reported depression and quality of life. All treatments and assessments will be conducted via the Internet and measurement points will be baseline, Week 2, post-treatment, and 4 months post-treatment.Discussion: There is no direct evidence of the effects of combining CBM and ICBT in SAD. Adding attention-training sessions to ICBT protocols could increase the proportion of participants who improve and recover through Internet-based self-help.
