Communities throughout the globe are increasingly being given the responsibility of resource management, making it necessary to understand the factors that lead to success in community-based management (CBM). Here, we assessed whether and how institutional design principles affect the ecological outcomes of CBM schemes for Arapaima sp., an important common-pool fishery resource of the Amazon Basin. selleck We quantified the degree of presence of Ostrom's (Science 325419-422, 1990) institutional design principles in 83 communities using a systematic survey, and quantitatively linked the design principles to a measure of ecological outcome (arapaima density) in a subset of 39 communities to assess their influence. To understand regional patterns of institutional capacity for CBM, we evaluated the degree of presence of each principle in all 83 communities. The principle scores were positively related to arapaima density in the 39 CBM schemes, explaining about half of the variation. Design principles related to defined boundaries and graduated sanctions exerted the strongest influence on the capacity of CBM to increase arapaima density. The degree to which most principles were present in all 83 communities was generally low, however, with the two most influential principles (defined boundaries and graduated sanctions) being the least present of all. Although the roles of the other principles (management rules, conflict resolution, collective action, and monitoring systems) are probably important, our results indicate that efforts aimed at strengthening the presence of defined boundaries and graduated sanctions in communities hold promise to improve the effectiveness of arapaima CBM regionally.East African ecosystems have been shaped by long-term socio-ecological-environmental interactions. Although much previous work on human-environment interrelationships have emphasised the negative impacts of human interventions, a growing body of work shows that there have also often been strong beneficial connections between people and ecosystems, especially in savanna environments. However, limited information and understanding of past interactions between humans and ecosystems of periods longer than a century hampers effective management of contemporary environments. Here, we present a late Holocene study of pollen, fern spore, fungal spore, and charcoal analyses from radiocarbon-dated sediment sequences and assess this record against archaeological and historical data to describe socio-ecological changes on the Laikipia Plateau in Rift Valley Province, Kenya. The results suggest a landscape characterised by closed forests between 2268 years before present (cal year BP) and 1615 cal year BP when there was a significant change to a more open woodland/grassland mosaic that continues to prevail across the study area. Increased amounts of charcoal in the sediment are observed for this same period, becoming particularly common from around 900 cal year BP associated with fungal spores commonly linked to the presence of herbivores. It is likely these trends reflect changes in land use management as pastoral populations improved and extended pasture, using fire to eradicate disease-prone habitats. Implications for contemporary land use management are discussed in the light of these findings.

This study aimed to compare day-specific associations of blood-brain barrier (BBB) disruption with neurological outcome in survivors of out-of-hospital cardiac arrest (OHCA) treated with target temperature management (TTM) and lumbar drainage.

This retrospective single-center study included 68 survivors of OHCA who underwent TTM between April 2018 and December 2019. The albumin quotient (Q

) was calculated as Q

 = albumin

/albumin

immediately (day 1) and 24 (day 2), 48 (day 3), and 72h (day 4) after the return of spontaneous circulation. The degree of BBB disruption was weighted using the following scoring system Q

value of 0.007 or less (normal), Q

value greater than 0.007-0.01 (mild), Q

value greater than 0.01-0.02 (moderate), and Q

value greater than 0.02 (severe). Points were assigned as follows 0 (normal), 1 (mild), 4 (moderate), and 9 (severe). Neurological outcome was determined at 6months after the return of spontaneous circulation, as well as cerebral performance category (CPC), dichvivors of OHCA treated with TTM with no contraindication to lumbar drainage. A large multicenter prospective study is needed to validate the utility of BBB disruption as a prognosticator of neurological outcome.

In this proof of concept study, QA was associated with poor neurological outcome in survivors of OHCA treated with TTM with no contraindication to lumbar drainage. A large multicenter prospective study is needed to validate the utility of BBB disruption as a prognosticator of neurological outcome.While often included in the spectrum of sexual minority identities, asexuality receives comparatively little attention. Awareness and understanding remains limited, and knowledge has been generated primarily from adult populations. This paper employs a sample of 711 self-identified asexual youth (aged 14-24, M = 17.43 years) who identified as members of the LGBTQ+ community to consider the implications of a number of different areas for service provision. Two-thirds (66.8%) of participants identified as gender minorities within the spectrum of transgender and non-binary identities. Findings include aspects of participants' LGBTQ+ developmental processes, including that only 14.3% had disclosed their LGBTQ+ status to everyone in their lives. However, just 2.4% had disclosed to no one. Their attraction and sexual activity were also explored, with 27.1% having never experienced any kind of romantic or sexual attraction and 20.6% having ever been sexually active. Findings regarding participants' accessing of LGBTQ+ health information and engagement in a range of offline and online LGBTQ+ community activities are also provided. Participants acquired more health information online than offline-including sexual health information. Recommendations for service provision, particularly implications for sexual health and Internet-based services, are discussed.
