A Reappraisal of the Luroy, Norway, Earthquake of 31 August 1819

Archives and libraries were visited to find previously unknown documents testifying to the Luroy, Norway, earthquake of 31 August 1819 in northernmost continental Europe. The focus here is on Sweden, Finland, and Russia, which are important for determining the area of perceptibility east of Norway. The new written sources include 12 notes or entries in original archived documents, six contemporary newspaper reports, and two recollections written down years later. The original documentation uncovered is contributory to establishing the authenticity of the observations in Finland and Sweden. The dates of the original documentation allow tracing of the dissemination of eyewitness accounts in writing from the inner area of perceptibility southward to the larger documentation and population centers. New sources of information include weather reports of the Royal Swedish Academy of Sciences, minutes of its meetings, and correspondence sent to the Senate in Finland. The minutes of meetings of the Academy indicate that ample data were collected in the Swedish province of Vasterbotten. We found no original Russian documentation but uncovered national newspapers that are more reliable than the previously used Parisian newspaper. To increase transparency, we provide the first list of macroseismic data points (MDPs) including the respective documentation that testify to the Luroy earthquake. A macroseismic intensity was assigned to a locality, using the European Macroseismic Scale of 1998, when adequate information was available. Accounting for the uncertainty of intensity assessment, the magnitude was estimated as moment magnitude M = 5.9 +/- 0.2, reconfirming the ranking as the largest onshore or nearshore earthquake in the historical seismicity record of Fennoscandia. In addition to the reappraisal of the 31 August 1819 earthquake, a macroseismic map is provided for the earthquake of 17 February 1819, which was felt in northern Finland and Sweden. Some of its MDPs were previously associated with the Luroy earthquake.Peer reviewe

Exploring the Lived Experiences of Pain in Military Families:A Qualitative Examination

Chronic pain in Canadian Veterans is twice that of the general population and the prevalence of their related mental health concerns is alarmingly high. This likely puts their children at an increased risk of developing pain and mental health problems that can pervasively impact daily life and persist into adulthood. Pain care and military culture of (acute and chronic) pain have been identified as a top priority of Canadian Veterans. This study aimed to gain an in-depth understanding of the pain experiences of Canadian Armed Forces families. Thirty-five semi-structured qualitative interviews were conducted. Demographic information was collected; age, gender, and ethnicity were reported. Twelve Canadian Armed Forces members/Veterans, 17 youth, and 6 spouses were interviewed. Ninety-two percent of Veteran participants reported chronic pain. Reflexive thematic analyses generated four themes: 1) Military mindset: herd culture and solider identity, 2) The culture of pain within military families, 3) Inseparability of mental health and pain, and 4) Breaking the cycle and shifting the military mindset. Military culture and identity create a unique context within which pain expression and experience is integrally shaped within these families. This study sheds light on how pain is experienced and perceived within military families and can inform research on and efforts to foster resilience in these families. Perspective: This is the first qualitative study to explore the lived experiences of pain in Canadian military families. Findings underscore the key role that military culture and identity plays in how pain is experienced and perceived in all family members.</p

The Role of Narrative in the Development of Children’s Pain Memories: Influences of Father- and Mother-Child Reminiscing on Children’s Recall of Pain

Negatively biased memories for pain (ie, recalled pain is higher than initial report) robustly predict future pain experiences. During early childhood, parent-child reminiscing has been posited as playing a critical role in how children's memories are constructed and reconstructed; however, this has not been empirically demonstrated. This study examined the role of parent-child reminiscing about a recent painful surgery in young children's pain memory development. Participants included 112 children (Mage = 5.3 years; 60% boys) who underwent a tonsillectomy and one of their parents (34% fathers). Pain was assessed in hospital and during the recovery phase at home. Two weeks after surgery, parents and children attended a laboratory visit to participate in a structured narrative elicitation task wherein they reminisced about the surgery. Four weeks after surgery, children completed an established pain memory interview using the same previously administered scales through telephone. Narratives were coded for style (elaboration) and content (pain and emotion) based on coding schemes drawn from the developmental psychology literature. Findings revealed that a more elaborative parental reminiscing style in addition to greater use of emotional words predicted more accurate/positively biased pain memories. Greater parental use of pain words predicted more negatively biased pain memories. Although there were no sex and parent-role differences in pain memory biases, mothers and fathers differed in how they reminisced with their boys vs girls. This research underscores the importance of parent-child reminiscing in children's pain memory development and may be used to inform the development of a parent-led memory reframing intervention to improve pediatric pain management.</p

Control of coordinatively unsaturated Zr sites in ZrO2 for efficient C–H bond activation

Due to the complexity of heterogeneous catalysts, identification of active sites and the ways for their experimental design are not inherently straightforward but important for tailored catalyst preparation. The present study reveals the active sites for efficient C–H bond activation in C1–C4 alkanes over ZrO2 free of any metals or metal oxides usually catalysing this reaction. Quantum chemical calculations suggest that two Zr cations located at an oxygen vacancy are responsible for the homolytic C–H bond dissociation. This pathway differs from that reported for other metal oxides used for alkane activation, where metal cation and neighbouring lattice oxygen form the active site. The concentration of anion vacancies in ZrO2 can be controlled through adjusting the crystallite size. Accordingly designed ZrO2 shows industrially relevant activity and durability in non-oxidative propane dehydrogenation and performs superior to state-of-the-art catalysts possessing Pt, CrOx, GaOx or VOx species

Cardiac T1 mapping enables risk prediction of LV dysfunction after surgery for aortic regurgitation

Background To assess whether cardiac T1 mapping for detecting myocardial fibrosis enables preoperative identification of patients at risk for early left ventricular dysfunction after surgery of aortic regurgitation. Methods 1.5 Tesla cardiac magnetic resonance imaging was performed in 40 consecutive aortic regurgitation patients before aortic valve surgery. Native and post-contrast T1 mapping was performed using a modified Look-Locker inversion-recovery sequence. Serial echocardiography was performed at baseline and 8 ± 5 days after aortic valve surgery to quantify LV dysfunction. Receiver operating characteristic analysis was performed to determine the diagnostic accuracy of native T1 mapping and extracellular volume for predicting postoperative LV ejection fraction decrease >−10% after aortic valve surgery. Results Native T1 was significantly increased in patients with a postoperatively decreased LVEF (n = 15) vs. patients with a preserved postoperative LV ejection fraction (n = 25) (i.e., 1,071 ± 67 ms vs. 1,019 ± 33 ms, p = .001). Extracellular volume was not significantly different between patients with preserved vs. decreased postoperative LV ejection fraction. With a cutoff-of value of 1,053 ms, native T1 yielded an area under the curve (AUC) of .820 (95% CI: .683–.958) for differentiating between patients with preserved vs. reduced LV ejection fraction with 70% sensitivity and 84% specificity. Conclusion Increased preoperative native T1 is associated with a significantly higher risk of systolic LV dysfunction early after aortic valve surgery in aortic regurgitation patients. Native T1 could be a promising tool to optimize the timing of aortic valve surgery in patients with aortic regurgitation to prevent early postoperative LV dysfunction

Mutuality as a method: advancing a social paradigm for global mental health through mutual learning

Purpose: Calls for “mutuality” in global mental health (GMH) aim to produce knowledge more equitably across epistemic and power differences. With funding, convening, and publishing power still concentrated in institutions in the global North, efforts to decolonize GMH emphasize the need for mutual learning instead of unidirectional knowledge transfers. This article reflects on mutuality as a concept and practice that engenders sustainable relations, conceptual innovation, and queries how epistemic power can be shared. // Methods: We draw on insights from an online mutual learning process over 8 months between 39 community-based and academic collaborators working in 24 countries. They came together to advance the shift towards a social paradigm in GMH. // Results: Our theorization of mutuality emphasizes that the processes and outcomes of knowledge production are inextricable. Mutual learning required an open-ended, iterative, and slower paced process that prioritized trust and remained responsive to all collaborators’ needs and critiques. This resulted in a social paradigm that calls for GMH to (1) move from a deficit to a strength-based view of community mental health, (2) include local and experiential knowledge in scaling processes, (3) direct funding to community organizations, and (4) challenge concepts, such as trauma and resilience, through the lens of lived experience of communities in the global South. // Conclusion: Under the current institutional arrangements in GMH, mutuality can only be imperfectly achieved. We present key ingredients of our partial success at mutual learning and conclude that challenging existing structural constraints is crucial to prevent a tokenistic use of the concept

Spatial and temporal trends of mercury in freshwater fish in Fennoscandia (1965-2015)

Source at http://hdl.handle.net/11250/2467116Mercury (Hg) emissions to the atmosphere cause elevated Hg levels in fish, even in many remote regions of the world. Here we present an extensive database of more than 50 000 measurements of Hg in fish, including 2 775 individual water bodies in Fennoscandia (Norway, Sweden, Finland, Russian part of Kola Peninsula) sampled between 1965 and 2015. The data have been analysed for spatial patterns and temporal trends, on raw and weight-adjusted data. The database presents a useful reference for assessment of impacts of environmental policy on Hg in freshwater fish (i.e. Convention on Long-Range Transboundary Air Pollution and The Minamata Convention on Mercury)

Toward a multi-level strategy to reduce stigma in global mental health: overview protocol of the Indigo Partnership to develop and test interventions in low- and middle-income countries

There is increasing attention to the impacts of stigma and discrimination related to mental health on quality of life and access to and quality of healthcare. Effective strategies for stigma reduction exist, but most evidence comes from high-income settings. Recent reviews of stigma research have identified gaps in the field, including limited cultural and contextual adaptation of interventions, a lack of contextual psychometric information on evaluation tools, and, most notably, a lack of multi-level strategies for stigma reduction. The Indigo Partnership research programme will address these knowledge gaps through a multi-country, multi-site collaboration for anti-stigma interventions in low- and middle-income countries (LMICs) (China, Ethiopia, India, Nepal, and Tunisia). The Indigo Partnership aims to: (1) carry out research to strengthen the understanding of mechanisms of stigma processes and reduce stigma and discrimination against people with mental health conditions in LMICs; and (2) establish a strong collaborative research consortium through the conduct of this programme. Specifically, the Indigo Partnership involves developing and pilot testing anti-stigma interventions at the community, primary care, and mental health specialist care levels, with a systematic approach to cultural and contextual adaptation across the sites. This work also involves transcultural translation and adaptation of stigma and discrimination measurement tools. The Indigo Partnership operates with the key principle of partnering with people with lived experience of mental health conditions for the development and implementation of the pilot interventions, as well as capacity building and cross-site learning to actively develop a more globally representative and equitable mental health research community. This work is envisioned to have a long-lasting impact, both in terms of the capacity building provided to participating institutions and researchers, and the foundation it provides for future research to extend the evidence base of what works to reduce and ultimately end stigma and discrimination in mental health
