Demanding Recognition: Equality, Respect, and Esteem

This article argues that we must distinguish between two distinct currents in the politics of recognition, one centred on demands for equal respect which is consistent with liberal egalitarianism, and one which centres on demands for esteem made on behalf of particular groups which is at odds with egalitarian aims. A variety of claims associated with the politics of recognition are assessed and it is argued that these are readily accommodated within contemporary liberal egalitarian theory. It is argued that, pace Taylor, much of what passes for `identity' or recognition politics is driven by demands for equal respect, not by demands for esteem/affirmation. Given the inherently hierarchical nature of esteem recognition, no liberal state can consistently grant such recognition. Furthermore, these demands pose the risk of intensifying intergroup competition and chauvinism. Esteem recognition is valuable for individuals, but plays a problematic role for egalitarian politics.

Platinum(II) phosphine and orotate complexes with aminopyridine co-ligands, and their molecular recognition via hydrogen bonding

The new complexes [Pt(dppp)(py)(2)][OTf](2), 1, [Pt(dppp)(2-ap)(2)][OTf](2), 2, [(dppp)Pt(mu -OH){mu -NH(C5H3N)NH2}Pt(dppp)][OTf](2), 3 (py=pyridine, 2-ap=2-aminopyridine, NH(C5H3N)NH2=2,6-diaminopyridine anion, dppp = 1,3-bis(diphenylphosphino)propane, OTf=O3SCF3) have been prepared via reactions between [Pt(dppp)(OTf)(2)] and pyridine, 2-aminopyridine or 2,6-diaminopyridine (2,6-dap) respectively. The amines exhibit a range of co-ordination modes. Pyridine and 2-aminopyridine co-ordinate to platinum through endo-nitrogen atoms in complexes 1 and 2, the latter existing as a pair of rotomers due to the steric hindrance introduced by the 2-substituent. However, 2,6-diaminopyridine co-ordinates to platinum through the exo-nitrogen of one amino group, to give the unusual mu -amido complex 3. Reaction of the known orotate chelate complex [Pt(PEt3)(2)(N,O-HL)] [HL=orotate, the dianion of 2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylic acid (orotic acid)] with 2,6-dap gave [Pt(PEt3)(2)(2,6-dap)(N-HL)] 4, which contains an unconventional monodentate orotate ligand. In this co-ordination mode the orotate retains an ADA hydrogen bonding site and was found to co-crystallise with 2,6-dap via complementary ADA:DAD triple hydrogen bonds to give [Pt(PEt3)(2)(N-HL)(2,6-dap)].2,6-dap, 5. Complex 5 exhibits a helical chain structure of associated [1+1] adducts in the solid state.

Sibling recognition in the rat

Mechanisms determining the ability of individuals to recognize their kin can be broadly divided into those prenatally determined and those postnatally determined. The role of both of these possibilities was examined in an investigation of sibling recognition in the rat (Rattus norvegicus). Rat pups were tested for their preference for ‘siblings’, (either littermates and genetic siblings—natural siblings; just littermates—any recognition due to postnatal factors; or just genetic siblings—any recognition due to prenatal factors) as opposed to unfamiliar age-mates between the ages of 6 and 22 days, and also for their ability to detect conspecific odour. The results indicate that rats can recognize their siblings (Experiment V) and this can be achieved solely postnatally (Experiments I, VI), or solely prenatally (Experiments II, VII). Other results demonstrated that rats, as early as day 2, and probably earlier, can detect and respond preferentially to conspecific odours (Experiments III, IV and VIII). The possibilities of how these mechanisms, both postnatal and prenatal, function in the acquisition of sibling recognition are discussed. This is the first study in which individuals separated from all genetic relations postnatally are shown to posses the ability to recognize kin.
