Childhood Peer Status and the Clustering of Adverse Living Conditions in Adulthood

Within the context of the school class, children attain a social position in the peer hierarchy to which varying amounts of status are attached. Several studies have shown that children’s peer status is associated with a wide range of social and health-related outcomes. These studies commonly target separate outcomes, paying little attention to the fact that such circumstances are likely to go hand in hand. The overarching aim of the present study was therefore to examine the impact of childhood peer status on the clustering of living conditions in adulthood. Based on a 1953 cohort born in Stockholm, Sweden, multinomial regression analysis demonstrated that children who had lower peer status also had exceedingly high risks of ending up in more problem-burdened clusters as adults. Moreover, these associations remained after adjusting for a variety of family-related circumstances. We conclude that peer status constitutes a central aspect of children’s upbringing with important consequences for subsequent life chances, over and above the influences originating from the family.childhood; peer status; cohort; life course; outcome profiles; living conditions

Experiments to investigate the utility of nearest neighbour metrics based on linguistically informed features for detecting textual plagiarism

Plagiarism detection is a challenge for linguistic models — most current implemented models use simple occurrence statistics for linguistic items. In this paper we report two experiments related to plagiarism detection where we use a model for distributional semantics and of sentence stylistics to compare sentence by sentence the likelihood of a text being partly plagiarised. The result of the comparison are displayed for visual inspection by a plagiarism assessor

A new species of Colletes (Hymenoptera: Apoidea: Colletidae) from northern Florida and Georgia, with notes on the Colletes of those states

Colletes ultravalidus Hall & Ascher, new species, is described from several sites in northwestern Florida and southeastern Georgia.  It is a member of the inaequalis species group, very similar to C. validus Cresson, a specialist of Ericaceae, but can be distinguished by an even more elongate malar area and the absence of conspicuous tergal fascia.  Colletes ultravalidus has been found flying from early winter to early spring when it forms nest aggregations in xeric sites adjacent to shrub bog or basin swamp, the habitat of Pieris phyllyreifolia (Hook.) DC. (Ericaceae), the most likely, but as yet unconfirmed, host plant of the new species.  State records of Colletes for Florida and Georgia are reviewed and discrepancies in taxonomy and distributional limits between Stephen’s 1954 revision of the genus and Mitchell’s 1960 monograph of eastern North American bees are noted.  We concur with Stephen that the distributions of several taxa in Colletes are more limited than that reported by Mitchell

Programmable biomaterials for dynamic and responsive drug delivery

Biomaterials are continually being designed that enable new methods for interacting dynamically with cell and tissues, in turn unlocking new capabilities in areas ranging from drug delivery to regenerative medicine. In this review, we explore some of the recent advances being made in regards to programming biomaterials for improved drug delivery, with a focus on cancer and infection. We begin by explaining several of the underlying concepts that are being used to design this new wave of drug delivery vehicles, followed by examining recent materials systems that are able to coordinate the temporal delivery of multiple therapeutics, dynamically respond to changing tissue environments, and reprogram their bioactivity over time
