Coping with Commitment: Projected Thermal Stress on Coral Reefs under Different Future Scenarios
BACKGROUND: Periods of anomalously warm ocean temperatures can lead to mass coral bleaching. Past studies have concluded that anthropogenic climate change may rapidly increase the frequency of these thermal stress events, leading to declines in coral cover, shifts in the composition of corals and other reef-dwelling organisms, and stress on the human populations who depend on coral reef ecosystems for food, income and shoreline protection. The ability of greenhouse gas mitigation to alter the near-term forecast for coral reefs is limited by the time lag between greenhouse gas emissions and the physical climate response. METHODOLOGY/PRINCIPAL FINDINGS: This study uses observed sea surface temperatures and the results of global climate model forced with five different future emissions scenarios to evaluate the "committed warming" for coral reefs worldwide. The results show that the physical warming commitment from current accumulation of greenhouse gases in the atmosphere could cause over half of the world's coral reefs to experience harmfully frequent (p> or =0.2 year(-1)) thermal stress by 2080. An additional "societal" warming commitment, caused by the time required to shift from a business-as-usual emissions trajectory to a 550 ppm CO(2) stabilization trajectory, may cause over 80% of the world's coral reefs to experience harmfully frequent events by 2030. Thermal adaptation of 1.5 degrees C would delay the thermal stress forecast by 50-80 years. CONCLUSIONS/SIGNIFICANCE: The results suggest that adaptation -- via biological mechanisms, coral community shifts and/or management interventions -- could provide time to change the trajectory of greenhouse gas emissions and possibly avoid the recurrence of harmfully frequent events at the majority (97%) of the world's coral reefs this century. Without any thermal adaptation, atmospheric CO(2) concentrations may need to be stabilized below current levels to avoid the degradation of coral reef ecosystems from frequent thermal stress events
Investigation of short-term surgical complications in a low-resource, high-volume dog sterilisation clinic in India
Abstract Background Surgical sterilisation is currently the method of choice for controlling free-roaming dog populations. However, there are significant logistical challenges to neutering large numbers of dogs in low-resource clinics. The aim of this study was to investigate the incidence of short-term surgical complications in a low-resource sterilisation clinic which did not routinely administer post-operative antibiotics. The medical records of all sterilisation surgeries performed in 2015 at the Worldwide Veterinary Service International Training Centre in Tamil Nadu, India were reviewed (group A) to assess immediate surgical complications. All animals in this group were monitored for at least 24 h post-surgery but were not released until assessed by a veterinarian as having uncomplicated wound healing. In the second part of this study from August to December 2015, 200 free-roaming dogs undergoing sterilisation surgery, were monitored for a minimum of 4-days post-surgery to further assess postoperative complications (group B). Results Surgery related complications were seen in 5.4% (95%CI, 4.5–6.5%) of the 1998 group A dogs monitored for at least 24 h, and in 7.0% (3.9–11.5%) of the 200 group B dogs monitored for 4 days. Major complications were classed as those requiring an intervention and resulted in increased morbidity or mortality. Major complications were seen in 2.8% (2.1–3.6%) and 1.5% (3.1–4.3%) of group A and B, respectively. Minor complications requiring little or no intervention were recorded for 2.6% (1.9–3.4%) for group A and 5.5% (2.8–9.6%) for group B. There was no evidence for a difference in complication rates between the two groups in a multivariate regression model. Conclusion This study demonstrated that high volume, low-resource sterilisation of dogs can be performed with a low incidence of surgical complications and low mortality

"Nu kommer hunden!" : Aktionsforskning om barn som läser för hundar med syfte att utveckla lässtunderna på svenska bibliotek
This master´s thesis in Library and Information Science examines the experiences of children who read to a dog. The purpose of this thesis is to examine the interactions between the librarian, the readingdog-handler, the child-ren and the dogs and what the benefits from the interactions might be. The aim is also to examine how the child-ren express their literacy during the readingsessions and how to develop the readingsessions at a specific library. The author follows a reading dog project for seven weeks, in collaboration with a specific school and library. Action research was used as a research strategy, and since action research is done on the basis of practice, a coll-laboration with the participating children, the librarian and the readingdog-handler was significant in this study.The theoretical framework concists of theory and concepts from the sociocultural theory developed by Ro-ger Säljö, and human-animal studies with concepts from Donna Haraway. The method used to collecet data was qualitative interviews, participant observation, logbook and tutoring. A total of 33 observations was collected, 33 short interviews were conducted and 6 tutoring meetings. Also the author, readingdog-handler and the lib-rarian kept a log for this seven week long readingdog project. A total of five third grade children participated in this study.Important results are that the children view the readingsessions as a schoolbased activity, but they would also read to a dog in their spare time. The interaction with the dog and the relationship between the child and the dog are important for the readingsessions to work well. The readingsessions have the potential to let children express and develop their literacy in several ways, though in this study literacy was expressed mainly by tradit-ional reading of printed books. The thesis also discuss to what extent the participant children are allowed to be involved in planning and developing the readingdog-sessions. All of the children participating in this study had a positive experience of the readingsessions and felt that their readingskills improved by reading to a dog

Distress Proneness as a Personalized Indicator of Cognitive Decline: : results from the Swedish National Study on Aging and Care (SNAC)
Distress proneness, as indicated by the personality trait neuroticism, has been linked with increased rates of a variety of age-related cognitive pathologies. The current study examined changes in cognitive ability over a six-year period in a 66-year-old cohort of aging individuals classified as highly distress prone. The sample population was drawn from the Swedish National study of Aging and Care database. The results of this paper indicate that distress proneness did not significantly impact cognitive decline over a six-year period in old age. Accordingly, several important distinctions should be made in order to understand why these results differ from those of previous reports concerned with similar topics
