BACKGROUND Twins may be at increased risk of dysglycaemic disorders due to adverse fetal conditions. Data from Africa regarding this association is limited. We studied impaired glucose tolerance (IGT) and other types of dysglycemia among twins and singletons in Guinea-Bissau. METHODS The study was conducted from February 2011 until March 2012 at the Bandim Health Project, a health and demogra...

We exposit two previously unpublished results due to Leo Harrington. The first result says that there exist arithmetical singletons which are arithmetically incomparable. The second result says that there exists a ranked point which is not an arithmetical singleton.

In this paper we introduce the relative belief of singletons as a novel probability distribution associated with a belief function. We discuss its nature in terms of degrees of belief under several different angles, its rationale in terms of game theory and its applicability to different classes of belief functions. We prove that it commutes with Dempster’s orthogonal sum, and meets a number of...

This paper presents an empirical study on the influence of singletons on the evaluation of coreference resolution systems. We present results on two English data sets used in the SEMEVAL 2010 shared task 1 and the CONLL 2011 shared task using the scorers of both shared tasks. We show that singletons, both in the gold standard and in the system output, have an immense impact on the overall evalu...

Thirty-two native American-English speaking children and adults reliably reproduced a non-contrastive segmental length distinction encoded in a set of monomorphemic nonce words. However, participants were unable to explicitly identify the contrast in a same/different judgment task. The results support the view that grammatically irrelevant, lexically specific temporal patterns can be learned an...

STUDY QUESTION Compared with singletons, what is the parent mental health, parent-child and couple relationship satisfaction, and child adjustment of 6- to 12-year-old assisted reproduction technology (ART) twins and their families? SUMMARY ANSWER There are no differences between 6- and 12-year-old ART twin and singleton families in parent mental health or family relationships; however, twins...
