- While some of the future impacts of global environmental change such as some aspects of climate change can be projected and prepared for in advance, other effects are likely to surface as surprises - that is situations in which the behaviour in a system, or across systems, differs qualitatively from expectations. Here we analyse a set of institutional and political leadership challenges posed by 'cascading' ecological crises: abrupt ecological changes that propagate into societal crises that move through systems and spatial scales. We illustrate their underlying social and ecological drivers, and a range of institutional and political leadership challenges, which have been insufficiently elaborated by either crisis management researchers or institutional scholars. We conclude that even though these sorts of crises have parallels to other contingencies, there are a number of major differences resulting from the combination of a lack of early warnings, abrupt ecological change, and the mismatch between decision-making capabilities and the cross-scale dynamics of social-ecological change.

- AIM: The aim of this study was to investigate heart rate variability (HRV) in a clinical sample of female adolescents with anxiety disorders (AD) and/or major depressive disorder (MDD) compared with healthy controls and to assess the effect of selective serotonin reuptake inhibitors (SSRI) on HRV. METHODS: Heart rate variability was measured in adolescent female psychiatric patients with AD and/or MDD (n = 69), mean age 16.8 years (range: 14.5-18.4), from 13 out-patient clinics and in healthy controls (n = 65), mean age 16.5 years (range: 15.9-17.7). HRV was registered in the sitting position during 4 min with no interventions. RESULTS: Logarithmically transformed high frequency HRV (HF), low frequency HRV (LF) and standard deviation of inter beat intervals (SDNN) were lower in the clinical sample compared with the controls (Cohen's d for HF = 0.57, LF = 0.55, SDNN = 0.60). This was not explained by body mass index, blood pressure or physical activity. Medication with SSRI explained 15.5% of the total variance of HF, 3.0% of LF and 6.5% of SDNN. CONCLUSIONS: Adolescent female psychiatric patients with AD and/or MDD show reduced HRV compared with healthy controls. Medication with SSRI explained a part of this difference.

- This study investigated whether there is a relationship between heart rate variability (HRV) versus lifestyle and risk factors for cardiovascular disease in a population of healthy adolescents. HRV is as an index of tonic autonomic activity and in adults HRV is related to lifestyle and risk factors for cardiovascular disease, but it is not known if this is the case in adolescents. HRV was registered for 4 min in sitting position in 99 healthy adolescents (age range 15 years 11 months-17 years 7 months) and repeated after 6 months. On both occasions there were significant correlations (P < 0.05) between physical activity and HRV, with respective r values: high frequency (HF) 0.26, 0.30; low frequency power (LF) 0.35, 0.29 and the standard deviation of inter-beat intervals (SDNN) 0.28, 0.37. There was no significant interaction between first and second measurements. In contrast, there were no correlations to sleeping patterns, eating habits and smoking. Risk factors for cardiovascular disease [body mass index (BMI = weight (kg)/length in m(2)), systolic blood pressure and p-glucose] did not show any repeatable significant correlations to HRV. Multiple regression models showed that physical activity was a predictor for HF, LF and SDNN in both measurements. In conclusion HF, LF and SDNN were reproducible after 6 months and were related to physical activity on both occasions.

Tools of Hegemony : Military Technology and Swedish-American Security Relations, 1945-1962

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This doctoral thesis analyze the process whereby Sweden gained access to American guided missiles during the late 1950s and early 1960s. It also tracks the Swedish efforts to develop guided missiles domestically. The concept of hegemony is used to interpret these processes, the dynamic in the Swedish-American relationship, and its consequences for the Swedish policy of neutrality.Sweden’s domestic guided missile development program, begun in the end of World War Two, met with great difficulties already by the end of the 1940s, and had entered a cul de sac by the early 1950s. The reason for this was a contunuous lack of funding and personnel, as well as a lack of foreign hardware and know-how. By 1947 the United States had largely established its hegemony in Western Europe, and the U.S. government then sought to gain the consent of the Swedish government as well. The U.S. government used its preponderant position, and pressured Sweden to adapt its policies by withholding vital technology from the Swedes. The U.S. refusal to deliver arms to a neutral Scandinavian Defense Union was significant in this respect. Sweden gradually gave its concurrence through a series of steps, most importantly the participation in the Marshall Plan in 1948, and COCOM in the summer of 1951. The confirmation of the U.S. government’s acceptance of Sweden came in the summer of 1952 when was made eligible to buy armaments in the United States under the Mutual Defense Assistance Act (MDAA).However, Sweden was not granted access to American guided missiles. This was an experience shared with most of the NATO countries (with the limited exception of Britain and Canada). During the course of the 1950s the United States was forced to change its position, due to prodding from the nato allies. The annual nato meetings were used as a platform by the nato countries in this endevour. The U.S. government reversed its non-disclosure policy in 1957 because of worries that its hegemonic position was threatened if it did not provide these weapons to its allies. Guided missile deliveries to Europe was used as a means to keep the alliance together, and to preserve U.S. hegemony in Western Europe.Because of its consent to U.S. hegemony Sweden gained access to U.S. missiles at the same time, and many times even before the NATO countries. Sweden was the first Western European country to purchase Sidewinder (1959) and Hawk (1962), and license manufactured two versions of the Falcon missile. Because of these deliveries the development of Swedish surface-to-air and air-to-air missiles was halted. Sweden was dependent upon the U.S. for deliveries of additional missiles in wartime, and this could have become a problem for Sweden’s ability to defend its territory against Western intrusions, since Sweden’s defense was based on help arriving from the West if Sweden was attacked by the USSR. The Swedish government, using the Royal Air Force Board as a proxy, signed a memorandum of Understanding in 1961 which gave the U.S. government the rigth to any improvements to the Falcon missiles, as well as the right to use them anywhere in the world. Sweden had thus de facto become a part of the U.S. military’s supply line.
