Understanding problems of access to oral health services requires Background: knowledge of factors that determine access. This study aimed to evaluate factors that determine access to oral health services among children aged <12 years in Peru between 2014 and 2015. We performed a secondary data analysis of 71,614 Peruvian children aged Methods: <12 years and their caregivers. Data were obtained...

Menopause remains an evolutionary puzzle, as humans are unique among primates in having a long post-fertile lifespan. One model proposes that intergenerational conflict in patrilocal populations favours female reproductive cessation. This model predicts that women should experience menopause earlier in groups with an evolutionary history of patrilocality compared with matrilocal groups. Using d...

Ackermann et al. briefly point out the potential significance of coordinated vocal behavior in the dual pathway model of acoustic communication. Rhythmically entrained and articulated pre-linguistic vocal activity in early hominins might have set the evolutionary stage for later refinements that manifest in modern humans as language-based conversational turn-taking, joint music-making, and othe...

In a distributed system, it is often important to detect the causal relationships between events, where event e 1 is causally before event e 2 if e 1 happened before e 2 and could possibly have aaected the occurrence of e 2. In this paper we argue that detecting causal relationships among events can be important for security, in the sense that it may be essential to the correct implementation o...

Mortality differentials among urban residents who were classified by period of residence in a rapidly industrialized city were analysed for those aged 20 and over dying between April 1974 and March 1978. The highest mortality in the male population appeared in the group with under 5 years of residence, and this was attributed to the high age-specific death rates at age 50 and over. In females, ...

Amongst the theoreticians there was a subspecies who interacted with experimentalists — these theorists tried to make sure that their ideas were testable and that someone tested them. Preeminent amongst these was Francis Crick who wrote all the quotes above shown in red italics (taken from Crick’s autobiographical book What Mad Pursuit: A Personal View of Scientific Discovery; Basic Books, New ...

the purpose of this study was to investigate the impact of 2 concept map (cm) learning strategies on iranian efl learners’ reading comprehension ability and learner autonomy. to this end, 60 iranian efl learners at the preintermediate level of language proficiency were randomly assigned to 2 groups. both groups received an 8-week instruction: one through teacher-constructed and the other throug...

BACKGROUND All current UK indices of socio-economic status have inherent problems, especially those used to govern resource allocation to the health sphere. The search for improved markers continues: this study proposes and tests the possibility that Council Tax Valuation Band (CTVB) might match requirements. PRESENTATION OF THE HYPOTHESIS To determine if there is an association between CTVB ...
