- 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.

The Importance of Effective Organizational Socialization for Preventing Stress, Strain, and Early Career Burnout : An Intensive Longitudinal Study of New Professionals
- 2022
-
Ingår i: International Journal of Environmental Research and Public Health. - : MDPI AG. - 1661-7827 .- 1660-4601. ; 19:12, s. 7356-7356

Tidskriftsartikel (refereegranskat)abstract
- Burnout was originally conceptualized based on experiences of new professionals. Role clarity, task mastery, and social acceptance are recognized as key resources enabling new professionals’ management of the challenges of the new profession. However, relations between these resources and stress, strain, and burnout have not yet been thoroughly investigated at professional entry. Increased understanding of these relations could have implications for strategies to prevent burnout. The aim of the study was to investigate within- and between-individual effects over the first months and relations to burnout at one-year post-entry. Data (n = 322) was collected weekly over the first 13 weeks and again 9 months later. Relationships were modelled using a multilevel regression model and correlation analysis. Results showed that on weeks when participants experienced higher role clarity, task mastery, and social acceptance, they reported significantly less stress, and that participants who experienced higher levels of the resources in general, reported significantly less strain. Levels of the resources at three months were related to symptoms of burnout at 12 months. The study findings provide support of the role of task mastery, role clarity, and social acceptance as resources buffering the impact of demands at professional entry on experiences of stress, strain, and burnout.

- The purpose of the study was to investigate the influence of flotation REST upon skilled and less skilled golfers’ anxiety in terms of physiological indicators of stress, self-rated anxiety scores, muscle tension, and the effect on golf putting. Prior to performing the putting task participants underwent a treatment of flotation REST or a period of resting in an armchair. Participants completed both treatments in a randomized order with a two-week interval. The results showed that both flotation REST and the armchair treatment reduced systolic blood pressure and heart rate, with no differences between treatments or athlete skill levels. No significant differences between treatments were revealed regarding self-ratings, level of muscle tension or putting precision. The results indicate that flotation REST may be useful for reducing negative symptoms related to stress and anxiety in general; however, no support for direct positive effects on golf performance were found.

Institutional and Political Leadership Dimensions of Cascading Ecological Crises

- 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.

Meta-Governance and Collaborative Crisis Management—Competing Rationalities in the Management of the Swedish Security Communications System
- 2017

Tidskriftsartikel (refereegranskat)abstract
- It is well recognized that contemporary crisis call for collaborative efforts across both organizational and jurisdictional boundaries. One of the key challenges for governments and public authorities responsible for organizing crisis management is to find adequate ways in which they can support decentralized and collaborative responses. This effort can be analyzed through the meta-governance approach that suggests that different instruments can be used to support decentralized collaborative efforts. This article analyzes the management of crisis communication in Sweden and the implementation of a new national Security Communications System (SCS) as a specific case of meta-governance. The main finding suggests that meta-governance may be impaired by combining different types of governance (sovereignty, markets, or network management) due to competing rationality invested in each governance style. The deadlock was, however, resolved by direct involvement and increased deliberation between the meta-governors and the end users as it generated a shared understanding of crisis management and the utility of a single SCS. Besides identifying the importance of direct involvement in terms of network management the article also suggests that meta-governors need to develop a deeper and more sensitive understanding of the self-organizing nature of networks in order to be able to support collaborative crisis management.

- Piracy can lead to risks so high that they, according to the International Maritime Organization, are tolerable only if risk reduction is not practicable or is disproportionate to the benefits achieved. Therefore, there is a need for reducing ship security risks in relation to antagonistic threats such as piracy. The aim of this study is to identify challenges for ship operators when developing their ship security management. Furthermore, this study also investigates two central aspects in the analysis: understanding the threat and understanding how a security threat affects the crew and operation of the ship. It is clear from the analysis that the importance of subjective aspects beyond a ship operators’ direct control is high. This seems to be the fact for all aspects of the risk management process. The situation is also dynamic as the security risk, as well as the risk perception, can change dramatically even though there are no actual operational changes. As a result, the ship security management process is highly iterative and depends on situations on board as well as conditions out of the ship operator’s control. In order to make ship security manageable, the risk management has to put particular focus on methodological understanding, relevant system understanding and well-defined risk acceptance criteria as well as on including all levels of the organization in the risk reduction implementation and on a continuous monitoring.

Tidskriftsartikel (refereegranskat)abstract
- The Muhammad cartoon crisis in 2005 provides an illustrative example of how crises travel across geographical boundaries, in this case, from a national newspaper into a full-fledged public diplomacy crisis at the international level. From a crisis management perspective, a multilevel setting poses a real challenge to actors trying to contain the situation at hand. Likewise, the multilevel nature of a crisis poses a challenge to crisis communication theories, which have traditionally focused on rhetorical strategies in single organizational crises. As a response, this article proposes a framework for examining crisis communication based on how actors’ framing impact the perceptions of arenas, stakeholders, and communication strategies.
