- Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

- Assessing ecological sustainability involves monitoring of indicators and comparison of their states with performance targets that are deemed sustainable. First, a normative model was developed centered on evidence-based knowledge about (a) forest composition, structure, and function at multiple scales, and (b) performance targets derived by quantifying the habitat amount in naturally dynamic forests, and as required for presence of populations of specialized focal species. Second, we compared the Forest Stewardship Council (FSC) certification standards' ecological indicators from 1998 and 2010 in Sweden to the normative model using a Specific, Measurable, Accurate, Realistic, and Timebound (SMART) indicator approach. Indicator variables and targets for riparian and aquatic ecosystems were clearly under-represented compared to terrestrial ones. FSC's ecological indicators expanded over time from composition and structure towards function, and from finer to coarser spatial scales. However, SMART indicators were few. Moreover, they poorly reflected quantitative evidence-based knowledge, a consequence of the fact that forest certification mirrors the outcome of a complex social negotiation process.

Bombattentatet i Oslo och skjutningarna på Utøya 2011 : Kamedo-rapport 97
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Fredagen den 22 juli 2011 kl. 15.25 detonerade en sprängladdning i regeringskvarteret i centrala Oslo. Bomben var mycket kraftig – åtta personer dödades, minst 90 skadades och kringliggande byggnader fick omfattande skador. Senare samma eftermiddag klev en man som utgav sig för att vara polis iland på ön Utøya, där det norska Arbeiderpartiets ungdomsförbund höll ett sommarläger. Väl iland på ön började mannen skjuta omkring sig. När han senare greps av polis hade 69 personer dödats och 65 skadats. De flesta var barn eller ungdomar. Händelserna den 22 juli involverade stora delar av det norska samhället. De många skadade krävde stora insatser från hälso- och sjukvården och det fanns ett stort behov av psykosocialt stöd till de många överlevande och deras anhöriga, samt till de avlidnas anhöriga. Vidare väckte händelserna ett mycket stort medialt intresse som de berörda aktörerna var tvungna att förhålla sig till.Rapporten omfattar en diskussion kring den norska hanteringen av 22 juli 2011, samt hur det svenska samhället hade kunnat hantera en motsvarande händelse.Tre huvudområden belyses: hälso- och sjkukvård, psykosocialt stöd samt kommunikation och mediehantering.

Militär akutsjukvård i fält : när den övade verkligheten blir verklig
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Aims: Governing for the Armed Forces health care is respect for human dignity and the view of each individual as irreplaceable. The quality of the military care will be at a level equivalent to that of today's civil peace healthcare, which requires that the training is of high quality. Casualty care in the military environment is a complex, challenging and dangerous task. Today there is a lack of knowledge about how to learn these skills. The purpose of the research was to identify the knowledge area pre-hospital care in the military environment by examining what doctors, nurses, paramedics and officers learn about military health care during preparation and exercise.Method: A phenomenographic approach was used in all sub-studies, and empirical data were collected by means of semi-structured interviews. Study I‐III are cross-sectional studies and study IV is a longitudinal study. Twelve registered nurses who had served in Bosnia were interviewed for study I, and 24 conscript paramedics were interviewed for study II. Study III included 20 officers in their pre-deployment training for service in Afghanistan and Liberia, and Study IV included 7 doctors and twenty nurses who previously had served in Afghanistan, Bosnia, Kosovo and Liberia.Results: Learning military health care by training and gaining experience can be seen as different abilities; interaction, action and reflection. In-depth analysis at a meta--‐level revealed that the integration between the military and military medical fields of knowledge was missing. The results indicate that participants' understanding of their respective fields of knowledge is inadequate and needs to be integrated in education in a clearer way.Implications: To create opportunities for better education and integration in these fields of knowledge are proposed (1) that the findings of the thesis could be utilised to develop the design of the curriculum (2) the inter-professional learning is introduced as a part of creating a safer and more effective pre-hospital care, (3) the clinical competence becomes part of the development of pre-hospital emergency care in the field, and (4) that the training is built according to the principle of "train as you fight" with emphasis on the requirements in the combat zone.

- Background:Disasters yield increased rates of psychological disorders decades later. Other consequences, however, have received little attention in the past.Objective:We aimed to examine diagnostic status and survivors’ views on disaster-related consequences and social support.Methods:A mixed-methods approach was used with 22 survivors (of 49 eligible) 15 years after a ferry disaster. Data collection included audiotaped interviews with open-ended questions and diagnostic assessment of Axis-I disorders.Results:The post-disaster incidence was 54% (12/22) for Axis-I disorders, and 45% (10/22) for full or subsyndromal posttraumatic stress disorder. Thematic analysis revealed that survivor perception of the longterm consequences included positive (character change) and negative aspects (being ascribed a survivor identity). Participants’ sought social support for several years, yet many felt hindered by experiential dissimilarity and distress of significant others.Conclusions:Axis-I disorders were prevalent, but not salient to survivors’ perceptions in the long-term. Postdisaster interventions need to attend to common barriers to support.

Posttraumatic stress in survivors 1 month to 19 years after an airliner emergency landing
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Posttraumatic stress (PTS) is common in survivors from life-threatening events. Little is known, however, about the course of PTS after life threat in the absence of collateral stressors (e.g., bereavement, social stigma, property loss) and there is a scarcity of studies about PTS in the long term. This study assessed the short- and long-term course of PTS, and the influence of gender, education and age on the level and course of PTS, in survivors from a non-fatal airliner emergency landing caused by engine failure at an altitude of 1 km. There were 129 persons on board. A survey including the Impact of Event Scale was distributed to 106 subjects after 1 month, 4 months, 14 months, and 25 months, and to 95 subjects after 19 years (response rates 64–83%). There were initially high levels of PTS. The majority of changes in PTS occurred from 1 to 4 months after the event. There were small changes from 4 to 25 months but further decrease in PTS thereafter. Female gender was associated with higher levels of PTS whereas gender was unrelated to the slope of the short- and long-term trajectories. Higher education was related to a quicker recovery although not to initial or long-term PTS. Age was not associated with PTS. The present findings suggest that a life-threatening experience without collateral stressors may produce high levels of acute posttraumatic stress, yet with a benign prognosis. The findings further implicate that gender is unrelated to trajectories of recovery in the context of highly similar exposure and few collateral stressors.

- The present study aimed to examine the prevalence of posttraumatic stress disorder (PTSD) in survivors with low levels of risk factors for PTSD. The sample included 142 adults (58% women, 54% university education, 93% employed/students/retired) on vacation in Southeast Asia during the 2004 Indian Ocean disaster. Semi-structured clinical interviews (SCID-I) were performed after 6 years including PTSD, depression, specific phobia, and alcohol abuse. The 6-year prevalence of PTSD was 11.3% and the current prevalence was 4.2%, with onset mainly within 1 month and remission within 3 years post-disaster. Suicidal ideation and comorbidity were common in PTSD cases. Lifetime prevalence of depression was 19%, specific phobia 7%, and alcohol abuse 4%. The findings suggest elevated levels of PTSD but not other disorders as compared with general population samples, but still lower levels than other disaster samples. Despite benign circumstances, however, the course and burden of PTSD were comparable to similar studies.

Tidskriftsartikel (refereegranskat)abstract
- This study evaluated the properties of Swedish versions of self-report measures of posttraumatic stress disorder (PTSD), with emphasis on the Impact of Event Scale–Revised (IES-R). Survey data from adult survivors 1, 3, and 6 years after the 2004 Indian Ocean tsunami (n = 1506) included the IES-R (from which the IES-6 was derived) and the 12-item General Health Questionnaire (GHQ-12). The PTSD Checklist (PCL) was included in one survey. A structured clinical interview was performed after 6 years (n = 142). Factor analyses of the IES-R and PCL indicated that a dysphoric-arousal model provided good fit invariant across assessments. Both measures were accurate in excluding PTSD while all measures provided poorer positive predictive values. The IES-R, but not the IES-6 and GHQ-12, evidenced stability across assessments. In conclusion, the Swedish IES-R and PCL are sound measures of chronic PTSD, and the findings illustrate important temporal aspects of PTSD assessment.

- Social support buffers the negative impact of stressful events. Less, however, is known about the characteristics of this association in the context of disaster and findings have been discrepant regarding direct and buffering effects. This study tested whether the protective effects of social support differed across levels of exposure severity (i.e., buffered distress) and assessed whether the buffering effect differed between event-specific and general distress. Participants were 4,600 adult Swedish tourists (44% of invited; 55% women) repatriated within 3 weeks after the 2004 Indian Ocean tsunami. A survey 14 months after the disaster included the Crisis Support Scale, the Impact of Event Scale-Revised (IES-R), and the General Health Questionnaire (GHQ-12). Social support buffered the negative impact of exposure on both outcomes. The support and distress association ranged from very small in participants with low exposure to moderate in those with high exposure (ηp2 = .004 to .053). The buffering effect was not found to differ between the IES-R and GHQ-12, F(2, 4589) = 0.87, p = .42. The findings suggest that social support moderates the stressor-distress relationship after disasters. This study might help explain discrepant findings and point to refinements of postdisaster interventions.
