Unlocking the mysteries of the past: Searching for clues in medieval manuscripts
No full textThis project looks at the reproduction of one mid-12th-century Roman text by analyzing sixteen versions of it that still exist, copied from c. 1160 through c. 1325. The author was Nicolaus Maniacutius, a cleric at St. John Lateran Basilica in Rome. That original copy is lost, but versions quickly appeared in monasteries and cathedrals in Italy, Germany, France, and England. Somehow, through networks of communication and travel, reproductions were made and collected by prominent monasteries and churches, and by the Guildhall, a secular institution in the City of London
Pulse oximetry adoption and oxygen orders at paediatric admission over 7 years in Kenya: a multihospital retrospective cohort study
No full textObjectives To characterise adoption and explore specific clinical and patient factors that might influence pulse oximetry and oxygen use in low-income and middle-income countries (LMICs) over time; to highlight useful considerations for entities working on programmes to improve access to pulse oximetry and oxygen.
Design A multihospital retrospective cohort study.
Settings All admissions (n=132 737) to paediatric wards of 18 purposely selected public hospitals in Kenya that joined a Clinical Information Network (CIN) between March 2014 and December 2020.
Outcomes Pulse oximetry use and oxygen prescription on admission; we performed growth-curve modelling to investigate the association of patient factors with study outcomes over time while adjusting for hospital factors.
Results Overall, pulse oximetry was used in 48.8% (64 722/132 737) of all admission cases. Use rose on average with each month of participation in the CIN (OR: 1.11, 95% CI 1.05 to 1.18) but patterns of adoption were highly variable across hospitals suggesting important factors at hospital level influence use of pulse oximetry. Of those with pulse oximetry measurement, 7% (4510/64 722) had hypoxaemia (SpO2 <90%). Across the same period, 8.6% (11 428/132 737) had oxygen prescribed but in 87%, pulse oximetry was either not done or the hypoxaemia threshold (SpO2 <90%) was not met. Lower chest-wall indrawing and other respiratory symptoms were associated with pulse oximetry use at admission and were also associated with oxygen prescription in the absence of pulse oximetry or hypoxaemia.
Conclusion The adoption of pulse oximetry recommended in international guidelines for assessing children with severe illness has been slow and erratic, reflecting system and organisational weaknesses. Most oxygen orders at admission seem driven by clinical and situational factors other than the presence of hypoxaemia. Programmes aiming to implement pulse oximetry and oxygen systems will likely need a long-term vision to promote adoption, guideline development and adherence and continuously examine impact
Author insights 2015 survey
No full textThe annual Author Insights Survey, run by Nature Publishing Group (NPG) and sister company Palgrave Macmillan forms part of a wider research programme which aims to understand general author attitudes and behaviours around publishing, to track any changes over time.
The survey is conducted for internal purposes each year to provide longitudinal data and track changes in attitudes and behaviours. This year’s survey included questions on topics as diverse as factors that contribute to a journal’s reputation, the value of services offered by publishers and authors’ ideal audiences for their research. Demographic questions were also included in the survey to enable analysis by fields such as region and discipline
When Do Children Dislike Ingroup Members? Resource Allocation from Individual and Group Perspectives
No full textDo children like ingroup members who challenge group norms about resource allocation? Further, do children evaluate from their own individual perspective? Participants (N = 381), aged 9.5 and 13.5 years, evaluated members of their own group who deviated from group norms about resource allocation by either: (1) advocating for equal allocation in contrast to the group norm of inequality; or (2) advocating for inequality when the group norm was to divide equally. With age, participants differentiated their own individual favorability from the group's favorability of deviant members of the ingroup. Further, when deciding between group loyalty and equal allocation, children and adolescents gave priority to equality, rejecting group decisions to dislike ingroup members who advocated for equality
Goal commitment and alignment of personal goals predict group identification only when the goals are shared
No full textSelfish pursuits of personal goals in group contexts may conflict with the group goal. Drawing on the shared reality theory and the intersubjective consensus approach to cultural dynamics, however, we propose that commitment to personal goals would be accompanied by greater group identification when individual group members realize that their personal goals are widely shared in the group. In one experiment (Study 1), we manipulated perceived sharedness of personal goals and found that commitment to personal goals correlated positively with group identification only when participants learned that their goals were shared. Subsequent surveys that incorporated a 3-month longitudinal design (Studies 2 and 3) further confirmed that goal commitment and alignment with personal goals predicted group identification only when the goals were shared in the group.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000302573100010&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Psychology, SocialSSCI7ARTICLE3425-4371
Fast identification of biological pathways associated with a quantitative trait using group lasso with overlaps.
No full textWhere causal SNPs (single nucleotide polymorphisms) tend to accumulate within biological pathways, the incorporation of prior pathways information into a statistical model is expected to increase the power to detect true associations in a genetic association study. Most existing pathways-based methods rely on marginal SNP statistics and do not fully exploit the dependence patterns among SNPs within pathways.We use a sparse regression model, with SNPs grouped into pathways, to identify causal pathways associated with a quantitative trait. Notable features of our "pathways group lasso with adaptive weights" (P-GLAW) algorithm include the incorporation of all pathways in a single regression model, an adaptive pathway weighting procedure that accounts for factors biasing pathway selection, and the use of a bootstrap sampling procedure for the ranking of important pathways. P-GLAW takes account of the presence of overlapping pathways and uses a novel combination of techniques to optimise model estimation, making it fast to run, even on whole genome datasets.In a comparison study with an alternative pathways method based on univariate SNP statistics, our method demonstrates high sensitivity and specificity for the detection of important pathways, showing the greatest relative gains in performance where marginal SNP effect sizes are small
Synergy and Group Size in Microbial Cooperation
No full textMicrobes produce many molecules that are important for their growth and development, and the exploitation of these secretions by nonproducers has recently become an important paradigm in microbial social evolution. Although the production of these public-goods molecules has been studied intensely, little is known of how the benefits accrued and the costs incurred depend on the quantity of public-goods molecules produced. We focus here on the relationship between the shape of the benefit curve and cellular density, using a model assuming three types of benefit functions: diminishing, accelerating, and sigmoidal (accelerating and then diminishing). We classify the latter two as being synergistic and argue that sigmoidal curves are common in microbial systems. Synergistic benefit curves interact with group sizes to give very different expected evolutionary dynamics. In particular, we show that whether and to what extent microbes evolve to produce public goods depends strongly on group size. We show that synergy can create an "evolutionary trap" that can stymie the establishment and maintenance of cooperation. By allowing density-dependent regulation of production (quorum sensing), we show how this trap may be avoided. We discuss the implications of our results on experimental design.</p
A pro-2 group with full normal Hausdorff spectra
No full textWe construct a 2-generated pro-2 group with full normal Hausdorff spectrum [0, 1] [0,1], with respect to each of the four standard filtration series: the 2-power series, the lower 2-series, the Frattini series, and the dimension subgroup series. This answers a question of Klopsch and the second author, for the even prime case; the odd prime case was settled by the first author and Klopsch. Also, our construction gives the first example of a finitely generated pro-2 group with full Hausdorff spectrum with respect to the lower 2-series
