Friendship as a moderator of the relationship between social skills problems and peer victimisation

Abstract: Previous research, primarily in North America, has found that individual factors (e.g., 'internalising problems') and social factors (e.g., friendship) interact to influence children's levels of peer victimisation. Some research has found that the identity of children's friends and friendship quality (as 'protective factors') are more important than the sheer number of friends. However, studies have produced conflicting findings. A peer nomination inventory was used to assess social skills problems, peer victimisation, peer acceptance, and several different aspects of friendship. Four hundred and forty-nine children aged 9 to 11 years completed the inventory at two time points over the course of an academic year. Social skills problems were found to predict an increase in peer victimisation over time. Two friendship variables were found to moderate this relationship: a) number of friends, and b) the peer acceptance of the very best-friend. The relationship was found to be weaker for those children with lots of friends and for those children with a 'popular' best-friend. The findings advance understanding of the factors that promote peer victimisation.

Radioiodination of alginate via covalently-bound tyrosinamide allows monitoring of its fate in vivo

Abstract: Tb monitor the fate of alginate following systemic administration, a method was developed that allowed the covalent incorporation of approximately 1 mol% tyrosinamide. The product could be radioiodinated to a high specific activity, and was subsequently stable on storage at 4°C for 30 days, with very little (c 1%) free [125I] iodide released over that period. Twenty-four hours following intravenous administration, the low molecular weight fraction (<48,000) of the injected polymer was excreted in the urine while the larger polymer fraction remained in the circulation and did not readily accumulate in any of the tissues. Almost all of the dose administered by intraperitoneal injection was transferred from the peritoneal cavity to the blood compartment within 24 h, with the low molecular weight fraction of the polymer excreted in the urine. Following subcutaneous administration, the majority (-70%) of the injected dose was retained at the site of injection at 24 h.

Technical Note-Analysis of a Heuristic for One Machine Sequencing with Release Dates and Delivery Times

Abstract: The single machine sequencing problem is considered in which each job has a release date, a processing time and a delivery time. The objective is to find a sequence of jobs which minimizes the time by which all jobs are delivered. A heuristic is presented which never deviates by more than 50% from the optimum.
