Do Children still need to Escape Childhood? A Reassessment of John Holt and his Vision for Children's Rights

The work of children’s liberationists have been long been critiqued for pushing the parameters of rights discourse too far; specifically, by suggesting that there are no significant differences between children and adults, including their ability for self-determination. John Holt’s 1974 text Escape from Childhood is one such work which was deemed highly controversial for its time. This article uses Holt’s Escape from Childhood as an overarching framework against which to examine the current state of play on children’s rights as explicated through the UN Convention on the Rights of the Child. It suggests that whilst Holt has often been critiqued for being too radical, in the context of current children’s rights discourse Holt’s visioning is not as radical as it might first appear.

Metagenomic characterisation of the viral community of lough neagh, the largest freshwater lake in Ireland

Lough Neagh is the largest and the most economically important lake in Ireland. It is also one of the most nutrient rich amongst the world's major lakes. In this study, 16S rRNA analysis of total metagenomic DNA from the water column of Lough Neagh has revealed a high proportion of Cyanobacteria and low levels of Actinobacteria, Acidobacteria, Chloroflexi, and Firmicutes. The planktonic virome of Lough Neagh has been sequenced and 2,298,791 2×300 bp Illumina reads analysed. Comparison with previously characterised lakes demonstrates that the Lough Neagh viral community has the highest level of sequence diversity. Only about 15% of reads had homologs in the RefSeq database and tailed bacteriophages (Caudovirales) were identified as a major grouping. Within the Caudovirales, the Podoviridae and Siphoviridae were the two most dominant families (34.3% and 32.8% of the reads with sequence homology to the RefSeq database), while ssDNA bacteriophages constituted less than 1% of the virome. Putative cyanophages were found to be abundant. 66,450 viral contigs were assembled with the largest one being 58,805 bp; its existence, and that of another 34,467 bp contig, in the water column was confirmed. Analysis of the contigs confirmed the high abundance of cyanophages in the water column.

Chemoenzymatic synthesis of enantiopure hydroxy sulfoxides derived from substituted arenes

Enantiopure β-hydroxy sulfoxides and catechol sulfoxides were obtained, by chemoenzymatic synthesis, involving dioxygenase-catalysed benzylic hydroxylation or arene cis-dihydroxylation and cis-diol dehydrogenase-catalysed dehydrogenation. Absolute configurations of chiral hydroxy sulfoxides were determined by X-ray crystallography, ECD spectroscopy and stereochemical correlation. The application of a new range of β-hydroxy sulfoxides as chiral ligands was examined.
