- Anonymity on the Internet is a contentious issue; by some seen as an important freedom to be protected, while others argue for increased identification to protect groups at risk of exploitation. The debate reflects a dichotomous view of online anonymity; you are, or you are not anonymous. However, anonymity is a complex process played out on different levels and defined by various actors. While empirical studies show this, theoretical synthesis is lacking. This essay provides perspective on anonymity online by comparing two critical cases, online auctions and online gaming, we corroborate results from a 4-year interdisciplinary project with researchers from sociology, economics, and computer and system sciences. We argue that one should talk about anonymities in plural form, as online anonymity is not a state but a relational process. We put forth a conceptual model, which unpacks online anonymity as interdependent macro structures – legal, commercial, and technological – and micro/meso facets – factual, social group, and physical – to be used in future research.

- This study explores how rationalization logic and rationalization processes influence digital gaming by looking at how players value and manage the time they spend on games. The study is framed in a discussion of leisure time, critical theories of computation and rationalization theory. Qualitative interview data is used in an inductive and phenomenology inspired approach. The results show two frames of understanding of gaming. First, games are perceived as media products and playing as a waste of time. Secondly, digital gaming is a hobby, a social activity highly valued within the framework of a rational time economy. We conclude that even though we are seeing a rationalization of leisure time in gaming, that rationalization process must be understood in the context of individualization within the new network society. This means that players are involved in a 'rational individualization' process where their management of leisure time and gaming activities are part of an ongoing identity project.

- Social anxiety disorder (SAD) is associated with considerable individual suffering and societal costs. Although there is ample evidence for the efficacy of cognitive behavior therapy, recent studies suggest psychodynamic therapy may also be effective in treating SAD. Furthermore, Internet-based psychodynamic therapy (IPDT) has shown promising results for addressing mixed depression and anxiety disorders. However, no study has yet investigated the effects of IPDT specifically for SAD. This paper describes a randomized controlled trial testing the efficacy of a 10-week, affect-focused IPDT protocol for SAD, compared with a wait-list control group. Long-term effects were also estimated by collecting follow-up data, 6, 12, and 24 months after the end of therapy. A total of 72 individuals meeting diagnostic criteria for DSM–IV social anxiety disorder were included. The primary outcome was the self-report version of Liebowitz Social Anxiety Scale. Mixed model analyses using the full intention-to-treat sample revealed a significant interaction effect of group and time, suggesting a larger effect in the treatment group than in the wait-list control. A between-group effect size Cohen’s d = 1.05 (95% [CI]: [0.62, 1.53]) was observed at termination. Treatment gains were maintained at the 2-year follow-up, as symptom levels in the treated group continued to decrease significantly. The findings suggest that Internet-based affect-focused psychodynamic therapy is a promising treatment for social anxiety disorder.

Tidskriftsartikel (refereegranskat)abstract
- PICALM, BIN1, CLU, and APOE are top candidate genes for Alzheimer's disease, and they influence episodic memory performance in old age. Physical activity, however, has been shown to protect against age-related decline and counteract genetic influences on cognition. The aims of this study were to assess whether (a) a genetic risk constellation of PICALM, BIN1, and CLU polymorphisms influences cognitive performance in old age; and (b) if physical activity moderates this effect. Data from the SNAC-K population-based study were used, including 2,480 individuals (age range = 60 to 100 years) free of dementia at baseline and at 3- to 6-year follow-ups. Tasks assessing episodic memory, perceptual speed, knowledge, and verbal fluency were administered. Physical activity was measured using self-reports. Individuals who had engaged in frequent health-or fitness-enhancing activities within the past year were compared with those who were inactive. Genetic risk scores were computed based on an integration of risk alleles for PICALM (rs3851179 G allele, rs541458 T allele), BIN1 (rs744373 G allele), and CLU (rs11136000 T allele). High genetic risk was associated with reduced episodic memory performance, controlling for age, education, vascular risk factors, chronic diseases, activities of daily living, and APOE gene status. Critically, physical activity attenuated the effects of genetic risk on episodic memory. Our findings suggest that participants with high genetic risk who maintain a physically active lifestyle show selective benefits in episodic memory performance.

- Social memory, including the ability to recognize faces and voices, is essential for social relationships. It has a large heritable component, but the knowledge about the contributing genes is sparse. The genetic variation underlying inter-individual differences in social memory was investigated in an exploratory sample (n = 55), genotyped with a chip comprising approximately 200,000 single nucleotide polymorphisms (SNPs), and in a validation sample (n = 582), where 30 SNPs were targeted. In the exploratory study face identity recognition was measured. The validation study also measured vocal sound recognition, as well as recognition of faces and vocal sounds combined (multimodal condition). In the exploratory study, the 30 SNPs that were associated with face recognition at puncorrected < 0.001 and located in genes, were chosen for further study. In the validation study two of these SNPs showed significant associations with recognition of faces, vocal sounds, and multimodal stimuli: rs1800779 in the gene encoding nitric oxide synthase 3 (NOS3) and rs3807370 in the gene encoding the voltage-gated channel, subfamily H, member 2 (KCNH2), in strong linkage disequilibrium with each other. The uncommon alleles were associated with superior performance, and the effects were present for men only (p < 0.0002). The exploratory study also showed a weaker but significant association with (non-emotional) word recognition, an effect that was independent of the effect on face recognition. This study demonstrates evidence for an association between NOS3 and KCNH2SNPs and social memory.

Towards an efficient use of infrastructure and the built environment : Essays in transport and housing economics
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- All four papers in the thesis share a common theme: how to achieve an efficient use of infrastructure and the built environment. In the presence of externalities, pricing according to the (short-run) marginal cost is one answer on how this can be achieved and the first two papers estimates parts of the marginal cost of traffic. Paper I examines the effect of road and railway noise on property prices. It uses the hedonic regression technique on a Swedish data set that contains information about both road and railway noise for each property, and finds that road noise has a larger negative impact on the property prices than railway noise. This is in line with the evidence from the acoustical literature which has shown that individuals are more disturbed by road than railway noise, but contradicts recent results from a hedonic study on data of the United Kingdom.Paper II estimates accident risks and marginal costs for railway level crossings in Sweden. The marginal effect of train traffic on the accident risk is used to derive the marginal cost per train passage that is due to level crossing accidents. The results show that both protection device, road type, traffic volume of the trains, and number of persons living nearby the level crossing have significant influence on the accident probability. The cost per train passage varies substantially depending on type of protection device, road type, the traffic volume of the trains, and number of persons living nearby the crossing.Paper III analyses the attitudes to the Stockholm Congestion Charges in 2007, when the congestion charges had been permanently reintroduced after the trial period in 2006. As expected, low car dependence and good transit supply are associated with high acceptability. But the two most important factors turn out to be beliefs about the charges’ effectiveness, and general environmental attitudes. The importance of beliefs and perceptions of the effects of the charges underscores the importance of both careful system design and careful evaluation and results communication. Paper IV analyses how a property tax reform in Sweden in 2008 that lowered the property tax for especially highly taxed single-family houses and increased the tax on profits from property sales influenced the housing tenure transistion of the elderly. The results show that the probability to exit homeownership for elderly households decreased after the tax reform in 2008. And more importantly, this probability decreased more the larger tax cut the household received. The effect is not only statically significant, it is also of a substantial size.

Tidskriftsartikel (refereegranskat)abstract
- The ability to recognize the identity of faces and voices is essential for social relationships. Although the heritability of social memory is high, knowledge about the contributing genes is sparse. Since sex differences and rodent studies support an influence of estrogens and androgens on social memory, polymorphisms in the estrogen and androgen receptor genes (ESR1, ESR2, AR) are candidates for this trait. Recognition of faces and vocal sounds, separately and combined, was investigated in 490 subjects, genotyped for 10 single nucleotide polymorphisms (SNPs) in ESR1, four in ESR2 and one in the AR. Four of the associations survived correction for multiple testing: women carrying rare alleles of the three ESR2 SNPs, rs928554, rs1271572 and rs1256030, in linkage disequilibrium with each other, displayed superior face recognition compared with non-carriers. Furthermore, the uncommon genotype of the ESR1 SNP rs2504063 was associated with better recognition of identity through vocal sounds, also specifically in women. This study demonstrates evidence for associations in women between face recognition and variation in ESR2, and recognition of identity through vocal sounds and variation in ESR1. These results suggest that estrogen receptors may regulate social memory function in humans, in line with what has previously been established in mice.

Tidskriftsartikel (refereegranskat)abstract
- PurposeThe aim of this study is to estimate monetary abatement values for road and rail traffic noise that can be used for policy purposes. However, a main objective is to critically discuss the assumptions necessary to convert the monetary values elicited in willingness to pay (WTP) studies to values than can be use for policy purposes.MethodsWe employ the hedonic regression technique on Swedish data to elicit individuals' preferences for noise abatement. Our elicited values are then converted to policy values and critically examined based on findings from a literature review.ResultsWe show that WTP for road and rail not only differs in levels but also that the relationship between the noise level and the marginal value differs between the two sources. We also show that a health cost component added to the WTP estimate, based on the assumption of uninformed property buyers, will be small but not negligible and that also modest differences in the assumption of the discount rates will have a significant effect on the estimated values.ConclusionsThe main implications from this study are: (i) WTP for road and railway noise abatement differs not only on absolute but also marginal levels, (ii) Even small differences in the chosen discount rate, which is necessary to convert WTP values from a hedonic price study to policy values, have large effects on the policy values, and (iii) We show how to add a health cost component to the WTP estimates in order for the monetary estimates to reflect the total social cost. However, we argue that the motivation for doing so is weak and that more research is needed on this issue.

Bullervärden för samhällsekonomisk analys : beräkningar för väg- och järnvägsbuller
- 2009

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Noise is a significant social problem. For example, more than 20 per cent of the European Union's population is exposed to higher noise than what is considered acceptable. The transport sector is a major contributor to society's increasing noise problem, due to increased traffic volumes and urbanization exposing more people to noise. Road traffic is admittedly the largest individual noise source in the transport sector, but other transport modes such as aircraft and railways are also responsible for considerable noise emissions. Noise entails costs for the society. This fact, and that society has different needs, means that policies and projects to reduce noise levels need to be evaluated to secure an efficient resource allocation. Benefit cost analysis is a powerful tool to evaluate noise abatement, but it requires both benefits and costs to be measured in a common metric, i.e. in monetary values. Today's official monetary values for all modes are based on the impact of road-traffic noise on property prices. It is a well established fact that the disturbance which individuals experience differs between modes, and therefore there is a need to estimate monetary values based on the respective modes. This report focuses on road and rail noise, two noise sources with different characteristics. This study describes the need to revise the current official Swedish policy values for noise abatement. Current values for road-traffic noise show a progressive relationship between the social cost and the noise level that is too strong, and values for railway noise has been missing and instead based on results for road noise. Valuation of health effects should also be based on EKM since it is sanctioned within the EU, instead of the approach now proposed by ASEK based on estimated total social costs from noise exposure in relation to estimates from willingness to pay studies.
