First insight into Araucaria araucana (Molina) K. Koch under its southernmost European growing condition: a proposed descriptor list for morphological characterization

Araucaria araucana is a south American endemic Conifer of conservation concern. After its introduction to Europe, this species has been often planted for ornamental purposes in parks and gardens, where its unusual appearance was admired. After the mid-1970s this tree received increasing attention from the nursery growers of Pistoia (Tuscany) and became of considerable economic importance. However, being one of the iconic threatened trees listed in CITES Appendix I, the international trade of these species is rigorously regulated. This study was aimed at developing a first morphological descriptor list for further phenotyping of in loco produced plant material. A first step of the research focused on the description and a better understanding of A. araucana phenological phases inferred from Mediterranean climate conditions. The second phase regarded the analysis of observed or measured morphological characteristics of the tree, branches, scales, inflorescences, fruits and seeds observed on a subset of 4 selected putative populations over a 3-year period of vegetative growth. The results allowed to select 39 most discriminant descriptors, which are presented together with their range of variability and classes. The achieved descriptor list represents a suitable tool for the selection of genotypes and for the breeding of A. araucana

Linking Social Protection Schemes: The Joint Effects of a Public Works and a Health Insurance Programme in Ethiopia

In developing countries and in particular in sub-Saharan Africa, social protection schemes tend to operate in silos. However, schemes targeting the same geographical areas may have synergies that have not yet been examined, and which are worth scrutinising. This paper contributes to this knowledge gap by examining the joint impacts of two social protection programmes in Ethiopia, that is, the Productive Safety Net Programme and a Community Based Health Insurance Scheme. Based on three rounds of individual level panel data and several rounds of qualitative interviews, we find that individuals covered by both programmes, as opposed to neither or only one of the two programmes, provide greater labour supply, have larger livestock holdings, and have a lower amount of outstanding loans. Furthermore, joint participation is associated with greater use of modern health care facilities as compared to participating only in the safety net programme. These results show that bundling of interventions enhances protection against multiple risks and that linking social protection schemes yields more than the sum of their individual effects

Development of pollination and in vitro germination techniques to improve the hybridization in Hydrangea spp.

Hydrangea is a genus of ornamental plants which is gaining new markets mainly as a fresh or dried cut flower, but it is also important as a pot plant and for landscaping. To expand its market, new hybrids should be developed. To increase the hybridization efficiency, some techniques were developed and tested: i) evaluation of two pollination systems; ii) comparison among fruit-cut systems before in vitro cultivation to develop embryos and to allow the growth of new genotypes; iii) evaluation of seed disinfection systems for in vitro germination; iv) sowing systems using seeds and fruits from stocks cultivated in two environments. To increase inter- and intra-specific hybridization, pollination by dispersion of previously collected pollen on the top of a corymb by a brush was more effective than pollination using the corymb itself as a brush. A longitudinal cut system can be considered the best treatment to be applied on fruits before in vitro cultivation to allow growth of seedlings. Sterilization of seeds can be done by immersion in a solution of commercial bleach for 5 minutes on MS culture medium with PPM®. When stocks are cultivated in greenhouses, in vitro contamination is lower and seeds have a better rate of germination. The results of these experiments were applied in a breeding program on Hydrangea using sexual crosses

Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study

Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P < 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P < 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk

State legitimacy and famines in Sub-Saharan Africa

Political Economy of famines mainly focuses on political regimes to understand the role of institutions. In this paper, we investigate a broader concept, state legitimacy, and its role on one specific development outcome, famine management. State legitimacy refers to the political history of a country, meaning the embedding of state and society. Using a database of Sub-Saharan countries observed from 1980 to 2005, we use three empirical strategies: logit on famine occurrence, negative binomial regression and Arellano-Bond dynamic model on the number of years of famines. They all lead to the same results: there is room for a political economy of famine based on an analysis of state. State legitimacy prevents famines, controlling for shocks countries might go through, and controlling for the quality of government. The main contributions of this paper are first to consider the role of state legitimacy in the political economy of famines and second to apply the concept in an empirical analysis, using for the first time a state legitimacy variable
