- Global change is predicted to cause shifts in species distributions and biodiversity in arctic tundra. We applied factorial warming and nutrient manipulation to a nutrient and species poor alpine/arctic heath community for seven years. Vascular plant abundance in control plots increased by 31%. There were also notable changes in cover in the nutrient and combined nutrient and warming treatments, with deciduous and evergreen shrubs declining, grasses overgrowing these plots. Sedge abundance initially increased significantly with nutrient amendment and then declined, going below initial values in the combined nutrient and warming treatment. Nutrient addition resulted in a change in dominance hierarchy from deciduous shrubs to grasses. We found significant declines in vascular plant diversity and evenness in the warming treatment and a decline in diversity in the combined warming and nutrient addition treatment, while nutrient addition caused a decline in species richness. The results give some experimental support that species poor plant communities with low diversity may be more vulnerable to loss of species diversity than communities with higher initial diversity. The projected increase in nutrient deposition and warming may therefore have negative impacts on ecosystem processes, functioning and services due to loss of species diversity in an already impoverished environment.

- Here we report from a experiment imposing different warming scenarios [control with ambient temperature, constant level of moderate warming for 3 years, stepwise increase in warming for 3 years, and one season of high level warming (pulse) simulating an extreme summer event] on an alpine ecosystem to study the impact on species diversity-biomass relationship, and community resistance in terms of biomass production. Multiple linear mixed models indicate that experimental years had stronger influence on biomass than warming scenarios and species diversity. Species diversity and biomass had almost humpback relationships under different warming scenarios over different experimental years. There was generally a negative diversity-biomass relationship, implying that a positive diversity-biomass relationship was not the case. The application of different warming scenarios did not change this tendency. The change in community resistance to all warming scenarios was generally negatively correlated with increasing species diversity, the strength of the correlation varying both between treatments and between years within treatments. The strong effect of experimental years was consistent with the notion that niche complementarity effects increase over time, and hence, higher biomass productivity over experimental years. The strongest negative relationship was found in the first year of the pulse treatment, indicating that the community had weak resistance to an extreme event of one season of abnormally warm climate. Biomass production started recovering during the two subsequent years. Contrasting biomass-related resistance emerged in the different treatments, indicating that micro sites within the same plant community may differ in their resistance to different warming scenarios.

Ägande- och förmögenhetsstrukturen och dess förändring sedan 1980
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Den här rapporten visar, genom omfattande studier av en mängd tidigare genomförda undersökningar om ägande och förmögenhetsförhållanden i Sverige, att koncentrationen av makt och ägande har blivit allt mer ojämlik. Resultaten är bland annat att: • Ungefär hälften av den samlade svenska ekonomin ägs numera från utlandet. • Det utländska ägandet på Stockholmsbörsen har ökat från 4 procent år 1979 till 39,4 procent 2016. • Det offentliga bolagsägandet har minskat och antalet anställda i statliga företag har halverats från 310 000 år 1980 till 158 000 år 2015. • Det institutionella ägandet har ökat och utgör cirka 20 procent av ägandet i de börsnoterade bolagen. • Det så kallade riskkapitalet har vuxit kraftfullt i omfattning och störst i sektorn är Wallenbergkontrollerade EQT. • I de stora börsnoterade bolagen på Stockholmsbörsen har den största ägarens andel av röstetalet ökat från i genomsnitt 26,8 procent till 31,2 procent av bolagsstämmans röster. • De 15 största finansfamiljerna styrde år 2017 bolag värda 4 935 miljarder kronor. Som jämförelse var Sveriges totala BNP samma år 4 604 miljarder kronor. • Familjen Wallenberg kontrollerade företag värderade till närmare 2 000 miljarder kronor. • Vad gäller de samlade förmögenheterna så har den allra rikaste procentens andel av de samlade förmögenheterna fördubblats från 20,5 procent 1978 till 39,6 procent 2006 och har fortsatt öka sedan dess. • Antalet svenska miljardärer har ökat från 83 personer 2001 till 178 år 2016. För att samhällsutvecklingen ska kunna vändas i riktning mot ökad jämlikhet krävs det att den breda vänstern tar kampen för att återskapa former för reglering och begränsningar av kapitalets makt både i Sverige men också internationellt i en allt mer globaliserad värld. Utvecklandet av ett nytt gemensamt projekt, som utgör ett verkligt alternativ till den ojämlikhetsskapande marknadsliberalismen, är av avgörande betydelse för socialdemokratins framtid.

Tidskriftsartikel (refereegranskat)abstract
- Measures that challenge the generation of waste are needed to address the global problem of the increasing volumes of waste that are generated in both private homes and workplaces. Source separation at the workplace is commonly implemented by environmental management systems (EMS). In the present study, the relationship between source separation at work and at home was investigated. A questionnaire that maps psychological and behavioural predictors of source separation was distributed to employees at different workplaces. The results show that respondents with awareness of EMS report higher levels of source separation at work, stronger environmental concern, personal and social norms, and perceive source separation to be less difficult. Furthermore, the results support the notion that after the adoption of EMS at the workplace, source separation at work spills over into source separation in the household. The potential implications for environmental management systems are discussed. © 2012 by the authors.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- Introduction Common mental disorders (CMD) are leading causes of decreased workability in Sweden and worldwide. Effective interventions to prevent or treat such disorders are important for public health. Objective To synthesize the research literature regarding occupational health service (OHS) interventions targeting prevention or reduction of CMD among employees. The effect on workability (sickness absence, return-to-work and self-reported workability) and on CMD symptoms was evaluated in a narrative analysis. Data sources The literature search was performed in four electronic databases in two searches, in 2014 and in 2017. Eligibility criteria (using PICO) Population: studies investigating employees at risk or diagnosed with CMD, as well as preventive workplace intervention targeting mental health. Intervention: studies where the recruitment or the intervention was delivered by the OHS or OHS personnel were included. Control: individuals or groups who did not receive the target intervention. Outcome: all types of outcomes concerning sickness absence and psychological health were included. Study quality was assessed using a Swedish AMSTAR-based checklist, and results from studies with low or medium risk of bias were narratively synthesized based on effect or absence thereof. Results Thirty-three studies were included and assessed for risk of bias. Twenty-one studies had low or medium risk of bias. In 18 studies, rehabilitation interventions were evaluated, 11 studies concerned interventions targeting employees at risk for developing CMD and four studies investigated preventive interventions. Work-focused cognitive behavioral therapy and problem-solving skill interventions decreased time to first return-to-work among employees on sick leave for CMD in comparison with treatment-as-usual. However, effect on return to full-time work was not consistent, and these interventions did not consistently improve CMD symptoms. Selective interventions targeting employees at risk of CMD and preventive interventions for employees were heterogeneous, so replication of these studies is necessary to evaluate effect. Limitations Other workplace interventions outside the OHS may have been missed by our search. There was considerable heterogeneity in the included studies, and most studies were investigating measures targeting the individual worker. Interventions at the workplace/organizational level were less common.

Tidskriftsartikel (refereegranskat)abstract
- An overview of the current situation in the out-of-home care in Norway and Sweden is presented in this article; also the development in later years is described and discussed. Socially, politically and culturally there are few differences between Norway and Sweden. Child protection and out-of-home placement of children and young people are integrated parts in the welfare state that are shared by the Nordic countries. It is a model that builds on principles of universalism and decommodification of social rights. The welfare model presupposes high public legitimacy for a high level of social expenditure. However the idea of marketization and privatization has also affected the welfare model in Sweden and Norway. Although there are more similarities than differences between the two countries' child protection systems, the article discusses some differences, for example the after care services, new groups of children and young people in the out-of-home care, like young unaccompanied asylum seekers. There are also some differences when it comes to privatization, the introduction of evidence-based methods in the child protection system and the tension between general and residual services for children and young people in the child protection system.

- Global urbanization and food production are in direct competition for land. This paper carries outa critical review of how displacing crop production from urban and peri-urban land to other areas– because of issues related to soil quality – will demand a substantially larger proportion of theEarth’s terrestrial land surface than the surface area lost to urban encroachment. Such relationshipsmay trigger further distancing effects and unfair social-ecological teleconnections. It risks also settingin motion amplifying effects within the Earth System. In combination, such multiple stressors set thescene for food riots in cities of the Global South. Our review identifies viable leverage points on whichto act in order to navigate urban expansion away from fertile croplands. We first elaborate on thepolitical complexities in declaring urban and peri-urban lands with fertile soils as one global commons.We find that the combination of an advisory global policy aligned with regional policies enablingrobust common properties rights for bottom-up actors and movements in urban and peri-urbanagriculture (UPA) as multi-level leverage places to intervene. To substantiate the ability of aligningglobal advisory policy with regional planning, we review both past and contemporary examples whereempowering local social-ecological UPA practices and circular economies have had a stimulatingeffect on urban resilience and helped preserve, restore, and maintain urban lands with healthy soils.

- Abstract Global change is predicted to have major impacts on alpine and arctic ecosystems. Plant fitness and growth will be determined by how plants interact with each other at smaller scales. Local-scale neighbourhood interactions may be altered by environmental pertubations, which could fundamentally affect community structure. This study examined the effects of seven years of experimental warming and nutrient addition on overall changes in the community structure and patterns of interspecific interaction between neighbouring plant species in two contrasting alpine plant communities, mesic meadow and poor heath, in subarctic Sweden. We used a network approach to quantify the dissimilarity of plant interaction networks and the average number of interspecific neighbourhood interactions over time in response to different environmental perturbations. The results revealed that combined warming and nutrient addition had significant negative effects on how dissimilar plant interaction networks were over time compared with the control. Moreover, plant–plant neighbourhood interaction networks were more dissimilar over time in nutrient-poor heath than in nutrient-rich mesic meadow. In addition, nutrient addition alone and combined nutrient addition and warming significantly affected neighbourhood species interactions in both plant communities. Surprisingly, changes in interspecific neighbourhood interactions over time in both communities were very similar, suggesting that the nutrient-poor heath is as robust to experimental environmental perturbation as the mesic meadow. Comparisons of changes in neighbouring species interactions with changes in evenness and richness at the same scale, in order to determine whether diversity drove such changes in local-scale interaction patterns, provided moderate evidence that diversity was behind the changes in local-scale interspecific neighbourhood interactions. This implied that species might interact at smaller scales than those at which community measures were made. Overall, these results demonstrated that global change involving increased nutrient deposition and warming is likely to affect species interactions and alter community structure in plant communities, whether rich or poor in nutrients and species.
