On the contribution of Aitken mode particles to cloud droplet populations at continental background areas ? a parametric sensitivity study
International audienceAitken mode particles are potentially an important source of cloud droplets in continental background areas. In order to find out which physico-chemical properties of Aitken mode particles are most important regarding their cloud-nucleating ability, we applied a global sensitivity method to an adiabatic air parcel model simulating the number of cloud droplets formed on Aitken mode particles, CD2. The technique propagates uncertainties in the parameters describing the properties of Aitken mode to CD2. The results show that if the Aitken mode particles do not contain molecules that are able to reduce the particle surface tension more than 30% and/or decrease the mass accommodation coefficient of water, ?, below 10?2, the chemical composition and modal properties may have roughly an equal importance at low updraft velocities characterized by maximum supersaturations CD2 exhibits largest sensitivity to the particle number concentration, followed by the particle size. Also the shape of the particle mode, characterized by the geometric standard deviation (GSD), can be as important as the mode mean size at low updraft velocities. Finally, the performed sensitivity analysis revealed also that the chemistry may dominate the total sensitivity of CD2 to the considered parameters if: 1) the value of ? varies at least one order of magnitude more than what is expected for pure water surfaces (10?2?1), or 2) the particle surface tension varies more than roughly 30% under conditions close to reaching supersaturation
Web-Based Interventions Supporting Adolescents and Young People With Depressive Symptoms: Systematic Review and Meta-Analysis
Women's knowledge about cervical cancer risk factors, screening, and reasons for non-participation in cervical cancer screening programme in Estonia
<p>Abstract</p> <p>Background</p> <p>The attendance rate in Estonian cervical cancer screening programme is too low therefore the programme is hardly effective. A cross-sectional population based survey was performed to identify awareness of cervical cancer risk factors, reasons why women do not want to participate in cervical screening programme and wishes for better organisation of the programme.</p> <p>Method</p> <p>An anonymous questionnaire with a covering letter and a prepaid envelope was sent together with the screening invitation to 2942 randomly selected women. Results are based on the analysis of 1054 (36%) returned questionnaires.</p> <p>Results</p> <p>Main reasons for non-participation in the national screening programme were a recent visit to a gynaecologist (42.3%), fear to give a Pap-smear (14.3%), long appointment queues (12.9%) and unsuitable reception hours (11.8%). Fear to give a Pap-smear was higher among women aged 30 and 35 than 50 and 55 (RR 1.46; 95% CI: 0.82-2.59) and women with one or no deliveries (RR 1.56, 95% CI: 0.94-2.58). In general, awareness of cervical cancer risk factors is poor and it does not depend on socio-demographic factors. Awareness of screening was higher among Estonians than Russians (RR 1.64, 95% CI: 1.46-1.86). Most women prefer to receive information about screening from personally mailed invitation letters (74.8%).</p> <p>Conclusions</p> <p>Women need more information about cervical cancer risk factors and the screening programme. They prefer personally addressed information sharing. Minority groups should be addressed in their own language. A better collaboration with service providers and discouraging smears outside the programme are also required.</p
Governing a multilevel and cross-sectoral climate policy implementation network
For national governments to meet their international climate change obligations they need to develop and implement plans that involve coordinating the actions of local, regional and national level actors from across multiple sectors. When this occurs, it can lead to the formation of a policy implementation network. Surprisingly, there is a limited understanding of the characteristics of the members of such networks, the structure of the multi-level and cross-sectoral ties among them, and about how they relate to how these networks are governed. This paper initiates the development of such knowledge by calculating a variety of network statistics to analyse the policy implementation network formed to carry out Ireland's signature climate policy-The Climate Action Plan 2019. Results show that national level actors dominate, and that cross-level and cross-sectoral collaboration are limited. The plan is governed by a network administrative organisation (NAO), with the Department of the Taoiseach (Irish Prime Minister) filling the role. How the network is structured and governed increases the likelihood that the network will be stable, have a unity of purpose and be able to meet its objectives. However, the dominance of national-level actors and its centralized structure are likely to make it challenging for the NAO to gain the support of local-level actors. This paper's methodological approach can be applied in other contexts to understand inter-actor relations and how these affect the responsibilities, challenges and opportunities of the actors involved in the implementation of a national environmental policy.Peer reviewe
Sattumaa vai suunnitelmaa? Metsäpolitiikan vaikutus pienmaanomistajien tiikin kasvatukseen Laosissa
This study analyses the impact of policy, legal and market conditions and specific incentives on smallholders’ interest and success in tree growing between 1990-2015 in Lao People’s Democratic Republic (Laos, Lao PDR). A review of previous studies and policy papers established the framework for this study, with primary data then collected from smallholders through semi-structured interviews in four villages. The interview questions covered household socioeconomic features, land use, information on woodlots, extension, and perceptions on drivers and challenges of tree growing. The findings indicate that policy objectives of promoting smallholder tree growing are weak at the district and village levels, and the only significant incentive, namely land allocation, has become ineffectual due to land scarcity and preference for other income sources. Tree growers intend to mainly preserve their present plantation areas, although their interest to expand tree growing areas is weak, and one third of non-growers see tree growing as a potential livelihood diversification option. If the promotion of smallholder tree growing is to be improved, the land and forest policy and associated legislation requires thorough revision and simplification, extension services must be made available, and specific incentives developed to allow smallholders to access land and meet their specific needs.This study analyses the impact of policy, legal and market conditions and specific incentives on smallholders’ interest and success in tree growing between 1990-2015 in Lao People’s Democratic Republic (Laos, Lao PDR).

Violent events, ward climate and ideas for violence prevention among nurses in psychiatric wards: a focus group study
Risk factors for post-weaning diarrhoea on piglet producing farms in Finland
Background: Post-weaning diarrhoea (PWD) is a significant gastrointestinal disease in pigs. It is
considered a multifactorial disease associated with proliferation of enterotoxigenic Escherichia coli
in the intestinal tract of affected pigs. The aim of this study was to analyse risk factors related to
the occurrence of PWD on Finnish piglet producing farms.
Methods: The data of a follow-up study of 73 conventional piglet producing farms was used in the
case-control study. The selection of the 41 PWD case and 28 control farms was based on the use
of antimicrobials for treating diarrhoea in weaned pigs and the answers related to the occurrence
of diarrhoea after weaning in the questionnaire. Four intermediate farms were excluded from the
statistical analysis.
Altogether 39 factors related to herd characteristics, weaner pig management and pig health were
studied. The median number of sows was 59.0 (IQR = 44.0; 74.5) and 52.5 (IQR = 36.8; 61.5) on
the case and the control farms, respectively.
The significances of the univariable associations between the explanatory variables and the
outcome variable were tested, and in the multivariate analysis quasibinomial generalized linear
models were applied.
Results: An increased risk of PWD was associated with the regimen of twice a day feeding and
feed restriction after weaning (P = 0.02; compared to feeding three or more meals a day or the use
of ad libitum feeding) and with a higher number of sows on the farm (P = 0.02; risk increasing with
increasing number of sows). Automatic temperature control was associated with a decreased risk
of PWD (P = 0.03; compared to manual temperature control).
Conclusion: Twice a day feeding of newly-weaned pigs should be avoided if the amount of feed
given is restricted. Variation in ambient temperature should be minimized in housing of newlyweaned
pigs and this can be achieved by using automatic temperature control. With increasing
number of sows in the herds the risk of PWD increases and more attention should be paid to
prevention of post-weaning diarrhoea
