- OBJECTIVE This study explored how professionals in inter-disciplinary teams perceived the implementation of the World Health Organization's International Classification of Functioning, Disability and Health, version for Children and Youth (ICF-CY) in Swedish habilitation services. DESIGN Descriptive longitudinal mixed-methods design. METHODS Following participation in a 2-day in-service training on the ICF-CY, 113 professionals from 14 interdisciplinary teams described their perceptions of the implementation of the ICF-CY at 3 consecutive time-points: during in-service training, after 1 year, and after 2.5 years. RESULTS Implementation of the ICF-CY in daily work focused on assessment and habilitation planning and required adaptations of routines and materials. The ICF-CY was perceived as useful in supporting analyses and in communication about children's needs. Professionals also perceived it as contributing to new perspectives on problems and a sharpened focus on participation. CONCLUSION Professionals indicated that the ICF-CY enhanced their awareness of families' views of child participation, which corresponded to organizational goals for habilitation services. An implementation finding was a lack of tools fitting the comprehensive ICF-CY perspective. The study points to the need for ICF-CY-based assessment and intervention methods focusing on child participation

- Purpose. This study was part of a larger work to develop an authentic measure consisting of code sets for self- or proxy-report of child participation. The aim was to identify common everyday life situations of children and youth based on measures of participation. Method. The study was descriptive in nature and involved several stages: systematic search of literature to find articles presenting measures for children and youth with disabilities, identifying measures in selected articles, linking items in included measures to the ICF-CY, analysing content in measures presented as performance and participation and identifying aggregations of ICF-CY codes across these measures. Results. A large number of measures for children and youth with disabilities were identified but only 12 fulfilled the inclusion criteria. A slight distinction in content and age appropriateness appeared. Measures presented as performance covered all the ICF-CY Activities and Participation chapters, whereas measures presented as participation covered five of nine chapters. Three common everyday life situations emerged from the measures: Moving around, Engagement in play and Recreation and leisure. Conclusion. Only a small number of life situations for children and youth emerged from items in selected measures, thus, other sources are needed to identify more everyday life situations.

- Purpose: The aim was to determine professionals' views of everyday life situations (ELS) of importance for children and to explore how ELS correlate with the construct "Participation". This study was part of a larger work to develop a structured tool with code sets to identify child participation and support children with disabilities to describe what matters most for them in intervention planning. Method: The study had a concurrent mixed methods design. Information from one open-ended question and questionnaires were linked to the ICF-CY component Activities and Participation. Two concurrent data sets were compared. Results: Proposed ELS were distributed across ICF-CY categories from low to high level of complexity and context specificity. The correlation with participation became stronger for the later chapters of the component (d7-d9). Differences between respondents due to working field, country, and children's ages were explored. Acts and tasks seemed most important for the youngest children, whereas ELS shifted towards societal involvement for adolescents. Conclusion: Eleven categories related to ICF-CY chapters d3-d9 emerged as ELS. Two age groups (infants/preschoolers and adolescents) are required to develop code sets for the new tool. The results need triangulation with other concurrent studies to provide corroborating evidence and add a family perspective.

- Background: Adults with cognitive disabilities often have difficulties in dealing with the complexity of everyday life. With cognitive assistive technology (e.g. electronic planning devices [EPDs] and individual support), they can bring order to their often chaotic life. Assumptions are that environmental factors influence with non-use of EPDs.Objective: To explore how adults with cognitive disabilities perceive the influence of environmental factors in the use of EPDs.Methods: A reference group with experience of use of EPDs assisted the researchers. Twelve adults with cognitive disabilities and experience of using EPDs participated. An interview guide was implemented covering environmental factors according to the International Classification of Functioning, Disability and Health. Qualitative content analysis was applied in the analyses.Results: Five categories and two themes emerged, which were integrated into a model of facilitating factors influencing the use of EPDs. Measures to prevent or eliminate negative influences of the device use are important to be taken.Conclusions: Professionals need more knowledge about EPDs, while users need individual adaption of the EPDs. EPDs need to be user-friendly, manageable and work in any seasons.

- The success of revenue management models depends to a large extent on the quality of historical data used to forecast future bookings. Several theoretical models and best practices of handing historical data have been developed over the years, that all rely on assumptions about underlying distribution and seasonality in the historical data. In this paper, we describe a novel method that compares the fingerprints of the departure to optimise and selects historical departures without making assumptions on data distribution or seasonality. By evaluating the method at the departure level and using the Nemenyi rank test, we show the method’s application in the ferry transportation business and discuss its advantages.

- In Sweden adults with major and sustainable disabilities can be granted publicly financed support in the form of personal assistance after assessment and decision-making in accordance with government rules. The purpose of the present study was to explore more deeply the encounters in close care relations between personal assistants and disabled persons of working age, as well as the prerequisites for and obstacles to the success of such encounters, this from the perspective of the personal assistants. Thirty-two personal assistants (22- to 55-year old) who worked for 32 persons with serious neurological diseases living at home were interviewed. The transcribed unstructured interviews were qualitatively analysed using latent content analysis. The analyses resulted in five main themes: Perceptive awareness, Entering into the other's role, Mutuality, Handling the relationship and Personal difficulties facing the assistant. These themes illustrated that a prerequisite for the encounter's being meaningful is that the assistant should be able to observe and understand the unique needs of the disabled person. The assistant must furthermore be able to put herself/himself into the other person's position. It is also important that the personal chemistry between the assistant and the disabled person should be good. Being able to share feelings and interests with the functionally impaired person provides the assistant with positive emotional confirmation of a good relationship. A distressing dilemma the assistant faces is that of distinguishing between the working relationship and the personal friendship. In this borderline area are found experiences, feelings and events that the assistant may view as negative or even unacceptable. This study contributes to the understanding of the complexity underlying the daily community care of disabled persons with an extensive need for care and assistance.

- We experimentally imposed three different kinds of warming scenarios over 3 years on an alpine meadow community to identify the differential effects of climate warming and extreme climatic events on the abundance and biomass of bryophytes and lichens. Treatments consisted of (a) a constant level of warming with open top chambers (an average temperature increase of 1.87 A degrees C), (b) a yearly stepwise increase of warming (average temperature increases of 1.0; 1.87 and 3.54 A degrees C, consecutively), and (c) a pulse warming, i.e., a single first year pulse event of warming (average temperature increase of 3.54 A degrees C only during the first year). To our knowledge, this is the first climate change study that attempts to distinguish between the effects of constant, stepwise and pulse warming on bryophyte and lichen communities. We hypothesised that pulse warming would have a significant short-term effect compared to the other warming treatments, and that stepwise warming would have a significant mid-term effect compared to the other warming treatments. Acrocarpous bryophytes as a group increased in abundance and biomass to the short-term effect of pulse warming. We found no significant effects of mid-term (third-year) stepwise warming. However, one pleurocarpous bryophyte species, Tomentypnum nitens, generally increased in abundance during the warm year 1997 but decreased in control plots and in response to the stepwise warming treatment. Three years of experimental warming (all treatments as a group) did have a significant impact at the community level, yet changes in abundance did not translate into significant changes in the dominance hierarchies at the functional level (for acrocarpous bryophytes, pleurocarpous bryophytes, Sphagnum or lichens), or in significant changes in other bryophyte or lichen species. The results suggest that bryophytes and lichens, both at the functional group and species level, to a large extent are resistant to the different climate change warming simulations that were applied.

Dominance hierarchies, diversity and species richness of vascular plants in an alpine meadow: Contrasting short and medium termresponses to simulated global change

Tidskriftsartikel (refereegranskat)abstract
- We studied the impact of simulated global change on a high alpine meadow plant community. Specifically, we examined whether short-term (5 years) responses are good predictors for medium-term (7 years) changes in the system by applying a factorial warming and nutrient manipulation to 20 plots in Latnjajaure, subarctic Sweden. Seven years of experimental warming and nutrient enhancement caused dramatic shifts in dominance hierarchies in response to the nutrient and the combined warming and nutrient enhancement treatments. Dominance hierarchies in the meadow moved from a community being dominated by cushion plants, deciduous, and evergreen shrubs to a community being dominated by grasses, sedges, and forbs. Short-termresponses were shown to be inconsistent in their ability to predict medium-term responses for most functional groups, however, grasses showed a consistent and very substantial increase in response to nutrient addition over the seven years. The non-linear responses over time point out the importance of longer-term studies with repeated measurements to be able to better predict future changes. Forecasted changes to temperature and nutrient availability have implications for trophic interactions, and may ultimately influence the access to and palatability of the forage for grazers. Depending on what anthropogenic change will be most pronounced in the future (increase in nutrient deposits, warming, or a combination of them both), different shifts in community dominance hierarchies may occur. Generally, this study supports the productivity-diversity relationship found across arctic habitats, with community diversity peaking in mid-productivity systems and degrading as nutrient availability increases further. This is likely due the increasing competition in plant-plant interactions and the shifting dominance structure with grasses taking over the experimental plots, suggesting that global change could have high costs to biodiversity in the Arctic. © 2014 Alatalo et al.

- Environmental changes are predicted to have severe and rapid impacts on polar and alpine regions. At high latitudes/altitudes, cryptogams such as bryophytes and lichens are of great importance in terms of biomass, carbon/nutrient cycling, cover and ecosystem functioning. This seven-year factorial experiment examined the effects of fertilizing and experimental warming on bryophyte and lichen abundance in an alpine meadow and a heath community in subarctic Sweden. The aim was to determine whether shortterm responses (five years) are good predictors of longer-term responses (seven years). Fertilizing and warming had significant negative effects on total and relative abundance of bryophytes and lichens, with the largest and most rapid decline caused by fertilizing and combined fertilizing and warming. Bryophytes decreased most in the alpine meadow community, which was bryophyte-dominated, and lichens decreased most in the heath community, which was lichen-dominated. This was surprising, as the most diverse group in each community was expected to be most resistant to perturbation. Warming alone had a delayed negative impact. Of the 16 species included in statistical analyses, seven were significantly negatively affected. Overall, the impacts of simulated warming on bryophytes and lichens as a whole and on individual species differed in time and magnitude between treatments and plant communities (meadow and heath). This will likely cause changes in the dominance structures over time. These results underscore the importance of longer-term studies to improve the quality of data used in climate change models, as models based on short-term data are poor predictors of long-term responses of bryophytes and lichens.

- 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.
