- Fireplaces are popular in Northern Europe. However, particle emissions from fireplaces have been identified as an environmental problem and a health problem. User behaviors affect particle emissions and the success of particle reducing technologies to a large extent. This interdisciplinary study aims to investigate why and how people use their fireplaces, including what emotions people associate with fire, and their interest in learning more about fire making and changing behavior related to fire making. It does so by applying an emotion regulation model in a novel way. In total, 146 Swedish individuals owning a fireplace (the majority had wood stoves, a few had tiled stoves, boilers or other types of fireplaces) participated in an online questionnaire about motives, behaviors, knowledge, and interest in learning and changing behavior. The most common motives for using a fireplace in this sample were complementary heating and “cozy fire making”. Our results suggest that watching a fire can aid in regulating emotions from unpleasant stress towards joy and provide a pleasant atmosphere for socialization, and that wood fuel may be a preferred complementary energy choice because it provides beautiful light, comfortable warmth, beautiful design and safety. People reporting emotional motives for using a fireplace also reported an interest in changing behavior. © 2020

Adopting Mobility-as-a-Service: An empirical analysis of end-users' experiences
- 2022

Ingår i: Travel Behaviour and Society. - : Elsevier BV. - 2214-367X .- 2214-3688. ; 28, s. 237-248

Tidskriftsartikel (refereegranskat)abstract
- Despite widespread interest, empirical research on how end-users perceive and use Mobility-as-a-Service (MaaS) is scarce. To address this knowledge gap, this paper analyzes the end-user process of adopting a MaaS service entitled EC2B, which was launched in Gothenburg (Sweden) in the spring of 2019. The contribution to the MaaS literature is three-fold. Firstly, the paper provides insight into potential user segments by describing the characteristics and motives of the studied pool of adopters. Secondly, it improves the understanding of the potential effects of MaaS by outlining how the EC2B service was used and how it influenced travel behavior. Thirdly, the paper informs strategies for facilitating MaaS adoption by outlining what types of drivers and barriers the end-users faced during different stages of the adoption process. The reported findings underscore previous assertions that MaaS is much more than just an app and a subscription plan and highlight the mutually reinforcing relationship between the introduction of MaaS and the implementation of policies aimed at reducing car use.

A psychometric evaluation of the Swedish translation of the Perceived Stress Scale: a Rasch analysis
- 2023
-
Ingår i: BMC Psychiatry. - : Springer Nature. - 1471-244X. ; 23
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Stress reflects physical and psychological reactions to imposing demands and is often measured using self-reports. A widely-used instrument is the Perceived Stress Scale (PSS), intended to capture more general aspects of stress. A Swedish translation of the PSS is available but has not previously been examined using modern test theory approaches. The aim of the current study is to apply Rasch analysis to further the understanding of the PSS’ measurement properties, and, in turn, improve its utility in different settings.Methods: Data from 793 university students was used to investigate the dimensionality of different version of the PSS (14, 10, and 4 items) as well as potential response patterns among the participants.Results: The current study demonstrates that the PSS-14 has two separate factors, divided between negatively worded items (perceived stress) and positively worded items (perceived [lack of] control), although with only the negative subscale exhibiting good reliability. Response patterns were analyzed using Differential Item Functioning, which did not find an influence of gender on any of the items, but for age regarding the positive subscale (items 6 and 9). The PSS-10 also demonstrated adequate reliability for the negative subscale, but the PSS-4 was not deemed suitable as a unidimensional scale.Conclusions: Based on the results, none of the versions of the PSS should be used by sum-scoring all of the items. Only the negative items from the PSS-14 or PSS-10 can be used as unidimensional scales to measure general aspects of stress. As for different response patterns, gender may nevertheless be important to consider, as prior research has found differences on several items. Meanwhile, content validity is discussed, questioning the relevance of anger and being upset when measuring more general aspects of stress. Finally, a table to convert the PSS-7 (i.e., negative items) ordinal sum scores to interval level scores is provided.

- We investigate the feasibility of applying standard text categorisation methods to patient text in order to predict treatment outcome in Internet-based cognitive behavioural therapy. The data set is unique in its detail and size for regular care for depression, social anxiety, and panic disorder. Our results indicate that there is a signal in the depression data, albeit a weak one. We also perform terminological and sentiment analysis, which confirm those results. © 2021 Association for Computational Linguistics

Tidskriftsartikel (refereegranskat)abstract
- This study done at the Vessel Traffic Services (VTS) explored how the VTS operators (VTSOs) communicated with ships and other actors in the maritime sociotechnical system and how decisions were made with regard to assisting traffic in maintaining safe passage in port areas, where most vessel movements are seen and accidents occur. The fieldwork was done during four independent visits to a VTS centre under the Swedish Maritime Authority, with a total sample of six VTSOs and one VTS instructor. The qualitative data were sorted and coded using a grounded theory approach. The data pointed at non-technical information processing and communication factors that play a role in decision-making and ultimately in safety. During protocol operations at the VTS, these factors influenced how VTSOs judged the skills of the vessels’ bridge teams, and how they approached them. This is a time where much effort is being put into upgrading technological systems, and these will have the power to change the ways in which the maritime network obtains and processes information, as well as how they can communicate with each other. The further development of technological systems, work protocols and training programmes can benefit from taking the soft aspects of communication and the needs of the operators and their tasks into account for the enhancement of safety.

ErgoVSM: A Tool for Integrating Value Stream Mapping and Ergonomics in Manufacturing
- 2016
-
Ingår i: Human Factors and Ergonomics in Manufacturing & Service Industries. - : Wiley. - 1090-8471 .- 1520-6564. ; 26:2, s. 191-204

Tidskriftsartikel (refereegranskat)abstract
- Value stream mapping (VSM) is a Lean tool aiming at waste reduction. Previous research suggests that the use of VSM may result in work intensification and thus an increased risk for the workers of developing work-related musculoskeletal disorders (MSD). In the current study, VSM was developed to also consider physical exposure in the analyzed production system (ErgoVSM). As the VSM, ErgoVSM is based on a participatory approach. ErgoVSM was tested in a Swedish manufacturing company. The results suggest that ErgoVSM catalyzes change processes to include intervention proposals emphasizing ergonomics in addition to waste reduction. Thus, ErgoVSM appeared useful for the investigated target group of production engineers and experienced operators. The performance improvements suggested when using the ordinary VSM seemed not to be hampered by adding the ergonomics complement. However, the use of ErgoVSM was somewhat more time-consuming than the use of VSM. In conclusion, ErgoVSM is suggested as a feasible tool to be used by production engineers and experienced operators for including ergonomics considerations in the rationalization process.

Leader-Member Exchange (LMX) and Psychosocial Factors at Work Among Healthcare Professionals
- 2014
-
Ingår i: Journal of Nursing and Care. - : OMICS Publishing Group. - 2167-1168. ; 3:5
-
Tidskriftsartikel (refereegranskat)abstract
- Aim: The study aims to examine the associations between leader–member exchange (LMX) and psychosocial factors at work. Methods: A questionnaire-based cross-sectional study was undertaken at four units in two not-for-profit hospitals in southwestern Sweden. The study sample included 240 employees. Results: Significant correlations were found between LMX items and most of the psychosocial domains and dimensions. The strongest correlations were found between the LMX item affect and rewards/recognition, role clarity and predictability, and the LMX item loyalty and rewards/recognition. In sum, high-quality LMX was associated with good psychosocial work conditions experienced by the employees. Conclusions: The results support possible ways for managers and employees to strengthen their relationships and this may in turn lead to more sustainable systems in health care.

- Aim: The aim of the current study was to investigate the impact of servant leadership dimensions on leader–member exchange (LMX) among health-care professionals. Background: Leadership support and the quality of the dyadic relationship between the leader and the employee are essential regarding the work environment and turnover intentions in health care. Method: A questionnaire-based cross-sectional study was undertaken at four hospital units in Sweden. The study sample included 240 employees. Results: Significant bivariate correlations were found between all servant leadership dimensions and LMX. The strongest correlations were found between ‘humility’ and LMX (r = 0.69, P < 0.001), and ‘empowerment’ and LMX (r = 0.67, P < 0.001). The hierarchical regression analyses indicated that ‘empowerment’, ‘humility’ and ‘stewardship’ explained about 55% of the variance in LMX. Conclusion: In our study servant leadership dimensions were strongly related to LMX. Implications for nursing management: The results identify specific servant leadership dimensions that are likely to be useful for developing a stronger exchange relationship between the leader (e.g. nursing manager) and individual subordinates in health care.

A virtual design studio for low frequency impact sound from walking

Tidskriftsartikel (refereegranskat)abstract
- Experience with wooden multi-storey houses have shown that impact sound insulation is one of most critical issues to ensure a good indoor environment. Even in cases where the impact sound insulation is fulfilled, people perceive the sound from e.g. walking neighbours as very disturbing. To investigate the subjective perception, a test facility is needed which allows for a coherent evaluation of different floor designs by listening test. The facility should ensure, that when comparing different floors, the same excitation by a walker and the same receiving room are involved. Only the floor design should be changed. As a consequence the spread in the data will only be due to the spread in the perception by subjects. In this paper a virtual design tool for low frequency impact sound insulation is presented, which consists of four parts; measured walking forces, floor models, an auralisation system which consists of a grid of loudspeakers simulating the vibration of the floor and a receiving room furnished as a common living room. In a pilot study a listening test is carried out for 13 different floors with different impact sound spectra at frequencies below 100 Hz. The results indicate that the judged annoyance strongly correlates with the judged loudness. However, there is a substantial spread observed in between the subjects participating in the listening tests. To understand this spread, a more extended study is needed with more participants and a classification of the subjects with respect to criteria such as noise sensitivity or age.
