- Ongoing urban exploitation is increasing pressure to transform urban green spaces, while there is increasing awareness that greenery provides a range of important benefits to city residents. In efforts to help resolve associated problems we have developed a framework for integrated assessments of ecosystem service (ES) benefits and values provided by urban greenery, based on the ecosystem service cascade model. The aim is to provide a method for assessing the contribution to, and valuing, multiple ES provided by urban greenery that can be readily applied in routine planning processes. The framework is unique as it recognizes that an urban greenery comprises several components and functions that can contribute to multiple ecosystem services in one or more ways via different functional traits (e.g. foliage characteristics) for which readily measured indicators have been identified. The framework consists of five steps including compilation of an inventory of indicator; application of effectivity factors to rate indicators' effectiveness; estimation of effects; estimation of benefits for each ES; estimation of the total ES value of the ecosystem. The framework was applied to assess ecosystem services provided by trees, shrubs, herbs, birds, and bees, in green areas spanning an urban gradient in Gothenburg, Sweden. Estimates of perceived values of ecosystem services were obtained from interviews with the public and workshop activities with civil servants. The framework is systematic and transparent at all stages and appears to have potential utility in the existing spatial planning processes.

Developing Theoretical and Empirical Definitions of Safety Problems in Driving Suitable for Active Safety Function Evaluation
- 2009
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In passive safety, the requirement specifications used for evaluation of protective functions are both standardised and specified at a high level of detail regarding evaluation scenario definition, performance metrics and pass/fail criteria. For active safety, while several propositions for evaluation scenarios have been made, neither these, nor performance metrics and pass/fail criteria have yet reached a similar level of detail and standardisation. The objective of this thesis is to address two underlying reasons for this difference. One is theoretical in nature. On a general level, a set of principles and concepts which capture the fundamental ideas of a field of science can be called a conceptual framework. For active safety function evaluation, such a framework is currently lacking. To address this issue, a conceptual framework called Situational control was developed. The framework integrates fundamental ideas relevant for active safety function evaluation into a holistic and practically applicable picture. Its applicability was demonstrated by applying it in the context of writing and implementing requirement specifications for active safety function evaluation.The second reason is of empirical character. To evaluate the extent to which active safety functions prevent and/or mitigate crashes, it is essential to characterize the sequence of events which leads to collisions in a way which includes information on causal factors. To do this, data from official databases (macroscopic data), and in-depth case studies is often used. Macroscopic data is usually statistically representative but has limited information on why crashes happen, while the opposite is true of case studies. Using the two in combination would therefore seem ideal. However, the principles for connecting them are far from clear and current approaches suffer inherent weaknesses. To address this issue, a generalization methodology which links information in case studies to macroscopic crash types, in a way which covers not only context but also causation similarity, was developed. The feasibility of the methodology was tested through application on three sets of intersection crash data. Results indicate that the methodology was sufficiently successful to warrant further exploration with larger data sets.

- The cat (Felis catus, Linneaus 1758) has lived around or with humans for at least 10,000 years, and is now one of the most popular pets of the world with more than 600 millionindividuals. Domestic cats have developed a more extensive, variable and complex vocal repertoire than most other members of the Carnivora, which may be explained by their social organisation, their nocturnal activity and the long period of association between mother and young. Still, we know surprisingly little about the phonetic characteristics of these sounds, and about the interaction between cats and humans.Members of the research project Melody in human–cat communication (Meowsic) investigate the prosodic characteristics of cat vocalisations as well as the communication between human and cat. The first step includes a categorisation of cat vocalisations. In the next step it will be investigated how humans perceive the vocal signals of domestic cats. This paper presents an outline of the project which has only recently started.

Tidskriftsartikel (refereegranskat)abstract
- Previous research has demonstrated that unfairness judgments of resource allocations become more complex when there are more than two recipients. In order to explain some of this complexity, we propose a set of psychological mechanisms that may underlie four different choices of maximally unfair resource allocations (MUA): Self-Single-Loser, Self-One-Loser-of-Many, Self-Single-Winner, and Self-One-Winner-of-Many. From this psychological theory, several predictions are derived and tested in vignette studies involving a total of 708 participants recruited online using MTurk. As predicted by our theory, (1) choices of MUA where there is a single loser were much more common when the allocated resource was of negative rather than positive valence, and (2) the amount of egoistic bias individuals exhibited when judging the unfairness in receiving a small rather than a large share in a non-extreme multi-party allocation was predicted by their choices of MUA. These findings suggest that an individual’s choice of MUA reveals some generally relevant principles of how unfairness is perceived in multi-party allocations. This opens up new lines of inquiry, especially regarding research on social dilemmas and social value orientation.

Wildlife and public perceptions of opportunities for psychological restoration in local natural settings

Tidskriftsartikel (refereegranskat)abstract
- Wildlife might be important to psychologically restorative values and disvalues of nature, as interactions with wildlife could trigger both positive and negative feelings. Research on positive experiences of human-wildlife interactions has largely involved participants who voluntarily sought out wildlife experiences or it has addressed encounters with non-threatening animals in urban green spaces. Less is known about the opportunities for psychological restoration in landscapes shared with mammals that are perceived to pose a threat to human activities and health. This study provides a nuanced understanding of the role of wildlife in public perceptions of the restorative potential and experience of psychological restoration in local natural settings. Twenty-eight participants (15 women, 13 men, 18-75 years) took part in focus group interviews subject to a reflexive thematic analysis. As an analytical framework, we used a theoretical model for how people appraise the relevance, implications, coping potential and norm congruence of human-wildlife interactions and how such appraisals may support or hinder the restoration experienced in local natural settings. Relevance appraisals revealed shifts in consideration of the presence of wildlife from an integrated part of the natural scenery (background) to a distinct figure (foreground). Implication appraisals revealed that wildlife encounters would hinder the experienced psychological restoration if the animal was appraised as dangerous, disgusting, causing a nuisance or destructive. Wildlife encounters would promote restoration if the animal displayed attractive traits, features or fascinating behaviour or movements, and if it opened engaging interaction situations. Coping strategies perceived as feasible to deal with negative implications of wildlife involved avoidance of the local natural setting, preparatory behaviour displayed before a visit and precautionary behaviour displayed during the visit. Important public health effects might be gained if wildlife policy and management explicitly consider what animals mean to the perceived restorative potential of local natural settings.Read the free Plain Language Summary for this article on the Journal blog. Forekomst av vilt levande djur kan ha betydelse for manniskors mojlighet till mental aterhamtning i naturen eftersom djurlivet kan ge upphov till bade positiva och negativa kanslor. Tidigare forskning om positiva upplevelser av vilt har foretradesvis handlat om situationer dar manniskor medvetet har sokt sig till en plats for att se djur, fokuserat djurarter som vanligtvis inte betraktas som farliga for manniskor, eller varit begransade till smavilt i urbana gronomraden. Daremot saknas kunskap om mojligheter till mental aterhamtning i naturomraden med storre daggdjur som ocksa kan upplevas utgora ett hot mot manniskors aktiviteter och halsa. Den har studien bidrar till en nyanserad forstaelse av viltets betydelse for allmanhetens upplevda mojligheter till mental aterhamtning i lokala naturomraden. Vi intervjuade 28 deltagare (15 kvinnor, 13 man, 18-75 ar) i fokusgrupper. Intervjuerna analyserades med sk reflexiv tematisk analys. I analyserna utgick vi ifran en teoretisk modell for manniskors bedomning av relevans och konsekvenser av interaktioner mellan manniska och vilt samt tillgang till strategier for att hantera sadana interaktioner och samstammighet med normer i dessa situationer. Modellen beskriver ocksa hur bedomningar kan stodja eller hindra upplevelsen av mental aterhamtning. Deltagarnas bedomning av viltets relevans for mental aterhamtning varierade avseende om djuren betraktades som en integrerad eller en unik framtradande del av naturlandskapet. Bedomningen av konsekvenser visade att moten med vilt levande djur upplevdes hindra den mentala aterhamtningen om djuret ansags vara farligt eller ackligt, orsaka olagenhet eller forstora for manniskor. Moten med vilt upplevdes stodja aterhamtning om djuret ansags ha ett attraktivt utseende eller positiva egenskaper, fascinerande beteenden eller rorelsemonster, eller om djuret skapade sarskilt engagerande situationer. De strategier som deltagarna bedomde som mojliga och tillgangliga for att hantera negativa konsekvenser av vilt var undvikande av lokala naturomraden, forberedelser som vidtogs innan ett eventuellt besok i naturomradet och forsiktighetsatgarder under tiden deltagarna vistades i naturomradet. Det kan finnas positiva effekter for folkhalsan om viltpolicy och forvaltning explicit beaktar betydelsen av vilt for manniskors upplevda mojlighet till mental aterhamtning i lokala naturomraden.

Ingår i: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 9

Tidskriftsartikel (refereegranskat)abstract
- The aim was to investigate effects of urban greenery (high vs. low naturalness) on place identity and wellbeing, and the links between place identity and wellbeing. It was shown that participants (Gothenburg, Sweden, N = 1347) estimated a stronger attachment/closeness/belonging (emotional component of place-identity), and more remembrance and thinking about and mental travel (cognitive component of placeidentity) in relation to high vs. low perceived naturalness. High naturalness was also reported to generate higher wellbeing in participants than low naturalness. Furthermore, place identity was shown to predict participants' wellbeing in urban greenery, accounting for 35% of variance explained by the regression. However, there was a stronger relationship between the emotional vs. the cognitive component of place identity and wellbeing. Finally, a significant role of place identity in mediating the naturalnesswellbeing relationship was shown, indicating that the naturalness-wellbeing connection can be partly accounted for by the psychological mechanisms of people-place bonding.

Energy efficiency at sea : An activity theoretical perspective on operational energy efficiency in maritime transport

- The mitigation of emission from shipping will require improvements in energy efficiency. In order to achieve this, sociotechnical changes are required, affecting all stakeholders within the shipping sector. Ship crews and their everyday work practices will play an especially important role in the transformation of the sector. It is therefore crucial to understand how new energy efficient technologies and practices are being introduced and enacted onboard ships. The case study reported in this paper investigates an attempt to improve the operational energy efficiency in a shipping company that was made by installing an energy monitoring system and introducing an energy saving policy onboard the ships in the fleet. The analytical framework in this paper is inspired by cultural-historical activity theory which is suggested as a novel and useful practice-based approach in energy studies. It is used in analyzing the contradictions and tensions in the work practices onboard the ships that preceded and followed the implementation of the energy monitoring system and energy saving policy. The empirical results revealed how the initial demand for operational energy efficiency and the subsequent introduction of the new monitoring system and policy gave rise to tensions in the existing activity systems onboard which crew members then tried, but did not always manage, to reconcile. It is concluded that a better understanding of the sociotechnical change processes, associated with organizational energy conservation and energy management, can be achieved if the situated paradoxes of practitioners’ everyday practices are examined.
