Post-compulsory education in England: choices and implications

Most students do not follow the ‘academic track’ (i.e. A-levels) after leaving school and only about a third of students go to university before the age of 20. Yet progression routes for the majority that do not take this path but opt for vocational post-compulsory education are not as well-known, which partly has to do with the complexity of the vocational education system and the difficulty of deciphering available data. If we are to tackle long-standing problems of low social mobility and a long tail of underachievers, it is essential that post-16 vocational options come under proper scrutiny. This paper is a step in that direction. We use linked administrative data to track decisions made by all students in England who left compulsory education after having undertaken the national examination – the General Certificate of Secondary Education (GCSE) – at age 16 in the year 2009/10. We track them up to the age of 21, as they progress through the education system and (for some) into the labour market. We categorise the many different types of post-16 qualifications into several broad categories and we look at the probability of achieving various educational and early labour market outcomes, conditional on the path chosen at age 17. We also take into account the influence of demographics, prior attainment and the secondary school attended. Our findings illustrate the strong inequality apparently generated by routes chosen at age 17, even whilst controlling for prior attainment and schooling up to that point

Synthesis and Stereochemical Characterization of a Novel Chiral α-Tetrazole Binaphthylazepine Organocatalyst

A novel α-tetrazole-substituted 1,1'-binaphthylazepine chiral catalyst has been synthesized and its absolute configuration has been determined by DFT computational analysis of the vibrational circular dichroism (VCD) spectrum of its precursor. The VCD analysis, carried out through the model averaging method, allowed to assign the absolute configuration of a benzylic stereocenter in the presence of a chiral binaphthyl moiety. The 1,1'-binaphthylazepine tetrazole and the nitrile its immediate synthetic precursor, have been preliminarily tested as chiral organocatalysts in the asymmetric intramolecular oxa-Michael cyclization of 2-hydroxy chalcones for the synthesis of chiral flavanones obtaining low enantioselectivity

Chirality Transfer in a Calixarene-Based Directional Pseudorotaxane Complex

Hexamethoxycalix[6]arene 3 forms a directional pseudorotaxane complex with the chiral axle (S)-(alpha-methyl-benzyl)benzylammonium 2(+). Between the two (endo-chiral)-2(+)@3 and (exo-chiral)-2(+)@3 pseudorotaxane stereoisomers, the former is preferentially formed. This result confirms the validity of the "endo-alpha-methyl-benzyl rule", previously reported by us. DFT calculations suggest that C-H horizontal ellipsis pi interactions between the methyl group of 2(+) and the calixarene aromatic rings, determine the stereoselectivity of the threading process toward the "endo-alpha-methyl-benzyl preference". An amplification of optical rotation is observed upon formation of the pseudorotaxane complex (endo-chiral)-2(+)@3 with respect to free axle 2(+). Thus, the specifical rotation of the 1:1 mixture of chiral 2(+)center dot B(ArF)(4)(-) salt and achiral 3 was augmented upon formation of the pseudorotaxane and DFT calculations were used to rationalize this result
