Mircea Eliade and the Perception of the Sacred in the Profane: Intention, Reduction, and Cognitive Theory
Building upon earlier analysis of Eliade's 'sacred' as 'the intentional object of human experience that is apprehended as the real' (Rennie 1996, 21) this article pursues the concept of the apprehension of the sacred in empirical experience as described by Eliade in his discussion of religious symbols. Using a vareity of visual analogies an attempt is made to understand what Eliade's understanding might imply and how this 'perception of the sacred' might come about. This necessitates some consideration of the status of 'intentional objects' and leads to a reflection on Eliadean claims concerning the 'irreducibility' of religion and of the relation of such claims to contemporary congnitive analyses of religion. The conclusion is that Eliade's understanding can be seen as complementary to recent cognitive theory, which demonstrates the coherence of that understanding
Secular trends in under-reporting in young people
Original article can be found at: http://journals.cambridge.org/action/displayJournal?jid=BJN Copyright The Authors. DOI: 10.1079/BJN20041307National survey data show that reported energy intake has decreased in recent decades despite a rise in the prevalence of obesity. This disparity may be due to a secular increase in under-reporting or a quantitatively greater decrease in energy expenditure. This study examines the extent of under-reporting of energy intake in the National Diet and Nutrition Survey (NDNS) in young people aged 4–18 years in 1997 using published equations to calculate estimated energy requirements. It explores secular changes by comparison with the Diets of British School Children (DBSC) survey in 10–11- and 14–15-year-olds in 1983. In the NDNS, under-reporting (estimated energy requirements – energy intake) represented 21 % of energy needs in girls and 20 % in boys. The magnitude of under-reporting increased significantly with age (P<0·001) and was higher in overweight than lean individuals over 7 years of age. To compare reported energy intake in DBSC and NDNS, the estimated physical activity level from dietary records (dPAL=reported energy intake/predicted BMR) was calculated. If there were no under-reporting, dPAL would represent the subject's true activity level. However, dPAL from the NDNS was significantly lower than that from the DBSC by 8 % and 9 % in boys and girls for those aged 10–11 years, and by 14 % and 11 % for 14–15-year-olds respectively, reaching physiologically implausible levels in the 14–15-year-old girls (dPAL=1·17). If activity levels have remained constant between the two surveys, under-reporting has increased by 8–14 %. The evidence supports a secular trend towards increased under-reporting between the two surveys, but the precise magnitude cannot be quantified in the absence of historical measures of energy expenditure.Peer reviewe
BlockDrop: Dynamic Inference Paths in Residual Networks
Very deep convolutional neural networks offer excellent recognition results,
yet their computational expense limits their impact for many real-world
applications. We introduce BlockDrop, an approach that learns to dynamically
choose which layers of a deep network to execute during inference so as to best
reduce total computation without degrading prediction accuracy. Exploiting the
robustness of Residual Networks (ResNets) to layer dropping, our framework
selects on-the-fly which residual blocks to evaluate for a given novel image.
In particular, given a pretrained ResNet, we train a policy network in an
associative reinforcement learning setting for the dual reward of utilizing a
minimal number of blocks while preserving recognition accuracy. We conduct
extensive experiments on CIFAR and ImageNet. The results provide strong
quantitative and qualitative evidence that these learned policies not only
accelerate inference but also encode meaningful visual information. Built upon
a ResNet-101 model, our method achieves a speedup of 20\% on average, going as
high as 36\% for some images, while maintaining the same 76.4\% top-1 accuracy
on ImageNet.Comment: CVPR 201
Term admissions to neonatal units in England: a role for transitional care? A retrospective cohort study
Objective
To identify the primary reasons for term admissions to neonatal units in England, to determine risk factors for admissions for jaundice and to estimate the proportion who can be cared for in a transitional setting without separation of mother and baby.
Design
Retrospective observational study using neonatal unit admission data from the National Neonatal Research Database and data of live births in England from the Office for National Statistics.
Setting
All 163 neonatal units in England 2011–2013.
Participants
133 691 term babies born ≥37 weeks gestational age and admitted to neonatal units in England.
Primary and secondary outcomes
Primary reasons for admission, term babies admitted for the primary reason of jaundice, patient characteristics, postnatal age at admission, total length of stay, phototherapy, intravenous fluids, exchange transfusion and kernicterus.
Results
Respiratory disease was the most common reason for admission overall, although jaundice was the most common reason for admission from home (22% home vs 5% hospital). Risk factors for admission for jaundice include male, born at 37 weeks gestation, Asian ethnicity and multiple birth. The majority of babies received only a brief period of phototherapy, and only a third received intravenous fluids, suggesting that some may be appropriately managed without separation of mother and baby. Admission from home was significantly later (3.9 days) compared with those admitted from elsewhere in the hospital (1.7 days) (p<0.001).
Conclusion
Around two-thirds of term admissions for jaundice may be appropriately managed in a transitional care setting, avoiding separation of mother and baby. Babies with risk factors may benefit from a community midwife postnatal visit around the third day of life to enable early referral if necessary. We recommend further work at the national level to examine provision and barriers to transitional care, referral pathways between primary and secondary care, and community postnatal care
Could human challenge studies for COVID-19 vaccines be justified in South Africa?
Although human challenge studies (HCSs) have been widely employed in vaccine development for malaria, dengue, typhoid and cholera, the role of this research design in COVID-19 remains controversial. While the potential social value of HCSs in the context of a pandemic is clear, bioethicists are divided on the ethics, given that effective treatment for COVID-19 has eluded us to date. While compelling ethics arguments have been offered on both sides of the debate, scientific and regulatory complexities may not have been fully appreciated. Furthermore, accelerated development of efficacious vaccine candidates in traditional clinical trials has diluted some of the arguments in favour of HCSs. In low- and middle-income country settings, including South Africa, the need for robust patient care conditions for the conduct of HCSs, coupled with considerations such as perceptions of risk, consent processes, remuneration, vaccine hesitancy, fear of exploitation and access to vaccines, makes HCSs challenging to justify
Physical activity patterns in a nationally representative sample of adults in Ireland
Original article can be found at: http://journals.cambridge.org/ Copyright - the authors. DOI: 10.1079/PHN2001192Objective To evaluate habitual levels of physical activity in a nationally representative sample of adults in Ireland. Design Cross-sectional survey using a self-administered questionnaire. Usual levels of work, recreational and household activities were evaluated in relation to anthropometric, demographic and socio-economic characteristics. The amount and intensity of all activities were quantified by assigning metabolic equivalents (METS) to each activity. Setting Republic of Ireland and Northern Ireland, 1997–1999. Subjects Random sample of 1379 adults aged 18–64 years. Results Men were approximately twice as active in work and recreational activity (139.7 ± 83.9 METS) as women (68.5 ± 49.8 METS; P 28kg m−2) or obese (BMI > 30kg m−2). Fewer obese subjects reported higher levels of work and leisure activities. However, a higher percentage of obese women reported participation in the higher levels of household activities. Participation rates in recreational activities were low. Walking was the most important leisure activity of both men (41%) and women (60%). In terms of hours per week spent in vigorous physical activity, men were more active than women, professional and skilled non-manual women were more active than women in other social classes, and younger subjects (aged 18–35 years) were more active than older subjects. Conclusions The holistic approach used in the assessment of physical activity in this study has revealed important and subtle differences in the activity patterns of men and women. Failure to fully characterise the respective activity patterns of men and women could lead to ill-informed public health policy aimed at promoting and sustaining lifetime habits of physical activity. The results suggest that simple population-focused programmes to promote physical activity are unlikely to offer the same chance of long-term success as more sensitive and individualised strategies.Peer reviewe
