Has modern Swedish forestry affected genetic diversity in Norway spruce stands?Dahlberg, Helena January 2015 (has links)
Norway spruce is one of two dominating species in Swedish forestry and the most economically important tree species in Sweden. In order to preserve the ability to adapt to a changing environment and to keep populations healthy, genetic diversity has to be preserved. When choosing a small number of individuals from a natural stand to establish a seed orchard the population size decrease. With only a small number of genetically different individuals the risk of inbreeding increase. Furthermore if many clones of the same tree are used in one seed orchard there is also an increased risk selfing. The aim of this study was therefore to investigate whether genetic diversity in Norway spruce differs between age groups and if this can be attributed to forestry practices. All sampling was done from a single location in Västerbotten, Sweden and the different age groups were chosen to represent stands not affected by the modern forest industry to recently planted forests. The chosen age groups are young (12-18 years), intermediate (30-45 years), and old (above 85 years). From each age group 150 individuals were sampled. With genomic microsatellite markers each individual was genotyped at eight simple sequence repeat (SSR) loci. Results show an overall high genetic diversity with an average expected heterozygosity (He) at 0.842 and low genetic differentiation with an average fixation index among populations (FST) of 0.003. The genetic diversity of each age group was also high (He 0.832 to 0.843) and the inbreeding coefficient ranged from 0.061 in the old group to 0.078 in the intermediate group. The pairwise FST value was highest between the old group and the young group but the differentiation was only 0.005 (P=0.001). An analysis of molecular variance also showed that only 0.34% of the total genetic variance was explained by differences among age groups. This study found little evidence for a decrease in genetic diversity due to forestry practices and revealed high genetic diversity and low differentiation between the age groups, indicating a healthy population.

Att vårda den inre hälsan. : Kan stödjande samtal vara ett nytt friskvårdsalternativ?Storbacka, Christine January 2013 (has links)
Arbetsmarknaden står inför ett generations- och paradigmskifte, när den äldre generationen går i pension och de yngre förväntas ta över. Samtidigt ökar den psykiska ohälsan och sjukskrivningen främst bland de yngre och stress rapporteras vara den stora bakomliggande orsaken; känslan av otillräcklighet och svårighet att få balans i livspusslet. Undersökningar poängterar att förebyggande arbete och tidiga insatser gynnar såväl medarbetares hälsa och arbetsplatsens ekonomi. Studiens syfte är att undersöka om samtalsstöd som ett nytt subventionerat friskvårdsalternativ uppfattas positivt, i synnerhet av Generation Y (födda 1982-1999). Resultatet av enkätundersökningen, genomförd på ett kommunkontor med 76 deltagare visade att 60% skulle boka samtal idag om det erbjöds som ett friskvårdsalternativ. Många uppgav att de hade en förstående person att samtala med. Stress, ökade krav i arbetslivet och arbetsbelastning angavs som största nyttan att samtala kring, främst av kvinnor och Gen Y. Resultatet bekräftar att det är önskvärt och behov av samtalsstöd föreligger.

Children's and adolescents' internal working models of peer interactionDolenszky, Eva. January 2000 (has links)
The present study examined whether children and adolescents develop mental models of peer relations that reflect observed gender differences in size and in density of friendship structures. A total of 278 children and adolescents, ranging from preschool level to CEGEP, participated in the study. Participants were given a questionnaire, consisting of schematic drawings of different forms of peer interactions, to assess their ideas about how friendships are organized for children of their age. Results indicated that both female and male participants at all grade levels judged typical boys to have a greater preference for group than dyadic interactions than did typical girls. Typical girls, however, were not judged to have preference for either dyadic or group interactions. Results also indicated that both female and male participants at all grades judged that the probability of mutual friends also being friends as higher for typical boys than for typical girls. Overall, the findings from the present study demonstrated that children and adolescents of both genders possess internal working models of peer interactions, beginning in early childhood, that are gender differentiated in a way that reflects patterns of behaviour.
