Trajectories of distress following the great East Japan earthquake : a multi-wave prospective study

The March 2011 Great East Japan Earthquake, tsunami, and nuclear leak were complex traumas. We examined psychological distress in the years following the earthquake using growth mixture modeling to classify responses from 2,599 linked respondents (2012–2016). We identified four classes of trajectories following the disaster: resilient (76% of respondents), delayed distress (8%), recovery (8%), and chronic distress (7%). Compared with the resilient class, other class members were less likely to be female and had less social support. Survivors in the recovery group were more likely to live in prefabricated housing. Although distress has decreased over time, specific populations continue to require targeted intervention

Psychological distress amongst tsunami refugees from the Great East Japan Earthquake

The 2011 Great Japan tsunami and nuclear leaks displaced 300,000, but there are no large studies of psychological distress suffered by these refugees Aims: To provide a first assessment of major factors associated with distress and dysfunctional behaviour following the disasters. Method: All refugee families living in Miyagi were sent a questionnaire 10-12 months after the disasters. 21 981 participants (73%) returned questionnaires. Questions assessed psychological distress (K6), dysfunctional behaviours, demographics, event exposure, change in physical activity, household visitors and emotional support. Results: Nine percent scored 13+ on k6 indicating risk of severe mental illness. Psychological distress was greater amongst Fukushima refugees. Demographic variables, family loss, illness history, and change in physical activity were associated with psychological distress and dysfunctional behaviours. Associations between psychological distress and dysfunction and visitors / supporters depended on relation to supporter. Conclusions: Practitioners need to recognise existing disease burden, community histories and family roles when intervening following disasters

Psychological distress and prejudice following terror attacks in France

Terrorist attacks have the capacity to threaten our beliefs about the world, cause distress across populations and promote discrimination towards particular groups. We examined the impact of two different types of attacks in the same city and same year on psychological distress and probable posttraumatic stress symptoms, and the moderating effects of religion or media use on distress/posttraumatic symptoms and inter-group relations. Two panel surveys four weeks after the January 2015 Charlie Hebdo attack (N= 1981) and the November 2015 Bataclan concert hall / restaurant attacks (N= 1878), measured intrinsic religiosity, social and traditional media use, psychological distress (K6), probable posttraumatic stress symptoms (proposed ICD-11), symbolic racism and willingness to interact with Muslims by non-Muslims. Prevalence of serious mental illness (K6 score > 18) was higher after November 2015 attacks (7.0 % after the first attack, 10.2% the second, χ2 (1) = 5.67, p<.02), as were probable posttraumatic stress symptoms (11.9% vs. 14.1%; χ2 (1) = 4.15, p<.04). In structural equation analyses, sex, age, geographic proximity, media use and religiosity were associated with distress, as was the interaction between event and religiosity. Distress was then associated with racism symbolism and willingness to interact with Muslims. Implications are considered for managing psychological trauma across populations, and protecting inter-group harmony

Psychological distress after the Great East Japan Earthquake : two multilevel 6-year prospective analyses

Background The Great East Japan Earthquake of 11 March 2011 led to the relocation of 300 000 survivors. Studies following disasters focus primarily on data collected in the immediate aftermath and neglect the influence of wider community factors. Aims A three-level prospective study examining associations between survivors' psychological distress and individual- and social-level factors in the 6 years following a complex disaster. Method We drew on two multi-wave data collections in the 6 years after the earthquake, using residents from different forms of housing. Sample 1 included six waves of private-housing residents from 2011 to 2016 (n = 1084 per wave), sample 2 five waves of residents living in prefabricated housing from 2012 to 2016 (n = 1515 per wave). We analysed prospective associations between distress and time (level 1), pre-existing disorders and disaster experiences and behaviours (level 2) and city-wide measures of support and physical activity (level 3). Results Multilevel models with random coefficients demonstrated greater distress in earlier waves (samples 1 and 2 respectively, adjusted β = −15 and β = −0.16, P < 0.001), among female respondents (β = 0.58, P = 0.01 and β = 1.74, P = 0.001), in those with a previous psychiatric history (β = 2.76, β = 2.06, P < 0.001) with diminished levels of activity post-earthquake (β = 1.40, β = 1.51, P < 0.001) and those lacking in social support (β = 1.95, β = 1.51, P < 0.001). Support from spouses and friends was most protective of psychological health. City-level support was negatively associated with distress, but only among those in prefabricated housing. Conclusions Psychological distress diminished with time, but varied across gender, psychiatric history, housing, levels of activity and availability of social support. Practitioners should consider individual- and city-level factors when devising effective interventions

The previous SARS outbreak in this country was accompanied by contradictory information, while worries about wide-spread influenza led to discrimination worldwide. Early understanding of public threat perceptions is therefore important for effective public health communication and intervention. Methods: We interviewed 1011 respondents by phone two weeks after the first case. Questions examined risk awareness and media use, beliefs about the emergence of the threat and those most at risk, anxiety about infection and preventive and avoidant behaviours. Results: Results demonstrate moderate levels of anxiety but relatively high levels of trust towards government officials. Threat emergence was associated with hygiene levels, temperature change, floating pigs in the Huangpu River and migration to the city. Anxiety predicted both recommended and non-recommended behavioural changes. Conclusions: Comparatively high levels of trust in Chinese government advice about H7N9 contrast positively with previous pandemic communications in China. Anxiety helped drive both recommended and non-recommended behaviours, with potentially important economic and social implications. This included evidence of 'othering’ of those associated with the threat (e.g. migrants). Findings emphasise the need to manage public communications early during new influenza outbreaks.Fudan Tydall Centre and Fudan Media and Public Opinion Center

The Haldane gap for the S=2 antiferromagnetic Heisenberg chain revisited

Using the density matrix renormalization group (DMRG) technique, we carry out a large scale numerical calculation for the S=2 antiferromagnetic Heisenberg chain. Performing systematic scaling analysis for both the chain length $L$ and the number of optimal states kept in the iterations $m$, the Haldane gap $\Delta (2)$ is estimated accurately as $(0.0876\pm0.0013)J$. Our systematic analysis for the S=2 chains not only ends the controversies arising from various DMRG calculations and Monte Carlo simulations, but also sheds light on how to obtain reliable results from the DMRG calculations for other complicated systems.Comment: 4 pages and 1 figur

The growth in newspaper coverage of tobacco control in China, 2000-2010

<p>Abstract</p> <p>Background</p> <p>Media coverage of tobacco-related issues can potentially shape individual beliefs, attitudes and behaviors about tobacco use. This study aims to describe news coverage of tobacco control related issues in Chinese newspapers from 2000 to 2010.</p> <p>Methods</p> <p>All 1149 articles related to tobacco control were extracted from the Database of Chinese Important Newspapers and content analyzed for the period Jan 1, 2000 to Dec 31, 2010. The changing pattern of tobacco control topic, article type, viewpoint, and article origin, and their relationship were analysed.</p> <p>Results</p> <p>News coverage of tobacco control related issues increased significantly (<it>p </it>< 0.01) from 2000 to 2010, with news coverage being relatively intensive in May and June (<it>p </it>< 0.01), around World No Tobacco Day. 24.9% (n = 286) of all articles focused on secondhand smoke, 25.3% (n = 291) warned about the dangers of active smoking, and 10.0% (n = 115) focused on prevention and cessation programs and campaigns. Tobacco control topics varied significantly between national vs city/regional newspapers (<it>χ</it>²= 24.09, <it>p </it>= 0.002) and article types (<it>χ</it>²= 193.35, <it>p </it>< 0.001). Articles in national newspapers had more coverage of the dangers of tobacco and on enforcing bans on tobacco-advertising. News stories centered around monitoring tobacco use and smoke free activity, while editorials focused on enforcing bans on tobacco-advertising, youth access and programs and campaigns. Letters to editors focused on the dangers of smoking, raising tax, and smoking cessation. More articles (50.4%) took an anti-tobacco position (compared with 10.5% which were pro-smoking), with the amount of negative coverage growing significantly across the decade. National articles tended to lean toward anti-tobacco, however, local articles tended mix of pro-tobacco and neutral/balance positions. Editorials seemed to be more anti-tobacco oriented, but letters to the editor tended to show a mix of anti-tobacco and pro-tobacco positions.</p> <p>Conclusion</p> <p>Chinese newspapers are giving increasing attention to tobacco control, but coverage remains lower than in the USA and Australia. Health workers need to give higher priority to efforts to increase news coverage beyond the present concentration around World No Tobacco Day and to develop strategies for making tobacco control issues more newsworthy to both national and local news outlets.</p

Check on the features of potted 20-inch PMTs with 1F3 electronics prototype at Pan-Asia

The Jiangmen underground neutrino observatory (JUNO) is a neutrino project with a 20-kton liquid scintillator detector located at 700-m underground. The large 20-inch PMTs are one of the crucial components of the JUNO experiment aiming to precision neutrino measurements with better than 3% energy resolution at 1 MeV. The excellent energy resolution and a large fiducial volume provide many exciting opportunities for addressing important topics in neutrino and astro-particle physics. With the container #D at JUNO Pan-Asia PMT testing and potting station, the features of waterproof potted 20-inch PMTs were measured with JUNO 1F3 electronics prototype in waveform and charge, which are valuable for better understanding on the performance of the waterproof potted PMTs and the JUNO 1F3 electronics. In this paper, basic features of JUNO 1F3 electronics prototype run at Pan-Asia will be introduced, followed by an analysis of the waterproof potted 20-inch PMTs and a comparison with the results from commercial electronics used by the container #A and #B
