Integrated Co-Professional Evaluation? Converging Approaches to School Evaluation Across Frontiers

This paper posits that almost all inspectorates are now following, if to varying degrees, a similar overarching ideology and methodology for school accountability and improvement. The first part of the paper provides an analysis of recent changes to school inspection policies across Frontiers. Using Ireland as a case example, the next part of the paper provides an analysis of Irish school inspection policies and practices that appear to mirror other school inspection systems. To test these assumptions, the paper then provides an analysis of a key informant interview with the Chief Inspector of schools in Ireland. The evidence suggests that there is an increasingly convergent approach to school evaluation discernible across all inspection frontiers. Among the many aspects of this changing landscape is the rapid pace at which schools have accepted school inspection frameworks and the emergence of a genuinely co-professional as opposed to co-existent mode of evaluation between the inspectorate and schools

Changes in rat n-3 and n-6 fatty acid composition during pregnancy are associated with progesterone concentrations and hepatic FADS2 expression

The mechanisms responsible for changes to long-chain polyunsaturated fatty acid (LC PUFA) status during pregnancy have not been fully elucidated. Tissue samples were collected from virgin and pregnant (day 12 and 20) female rats. LC PUFA status, sex hormone concentrations and hepatic mRNA expression of FADS1, FADS2 and elongase were assessed. Day 20 gestation females had higher plasma and liver docosahexaenoic acid and lower arachidonic acid content than virgin females (P<0.05). There was higher FADS2 mRNA expression during pregnancy (P=0.051). Progesterone and oestradiol concentrations positively correlated with hepatic FADS2 mRNA expression (P=0.043, P=0.004). Progesterone concentration positively correlated with hepatic n-6 docosapentaenoic acid content (P=0.006), and inversely correlated with intermediates in LC PUFA synthesis including n-3 docosapentaenoic acid, ?-linolenic acid and 20:2n-6 (P<0.05). Changes in progesterone and oestradiol during pregnancy may promote the synthesis of LC PUFA via increased FADS2 expression

Double Helices of a Pyridine-Appended Zinc Chlorophyll Derivative

Self-assembled structures formed from a pyridine-appended zinc chlorophyll derivative are reported. While the zinc complex forms cyclic oligomers in chloroform solution, as indicated by ¹H NMR studies (including diffusion-ordered spectroscopy), vapor pressure osmometry, and cold-spray ionization mass spectrometry, it forms double-stranded helical coordination polymers in the solid state, as revealed by single-crystal X-ray analysis
