Recognition and Redistribution in Theories of Justice Beyond the State

We consider here how cultural and socioeconomic dimensions of justice beyond the state are related. First we examine cosmopolitan theories that have drawn on John Rawls's egalitarian liberal framework to argue that a just global order requires substantive, transnational redistribution of material resources. We then assess the view, ironically put forward by Rawls himself, that this perspective is ethnocentric and insufficiently tolerant of non-liberal cultures. We argue that Rawls is right to be concerned about the danger of ethnocentrism, but wrong to assume that this requires us to reject the case for substantive redistribution across state boundaries. A more compelling account of justice beyond the state will integrate effectively socioeconomic and cultural aspects of justice. We suggest that this approach is best grounded in a critical theory of recognition that responds to the damage caused to human relations by legacies of historical injustice.

Embryo retrieval and kin recognition in an amphipod (Crustacea)

Active maternal care directed towards embryos within the brood pouch has been identified in amphipod crustaceans from harsh aquatic environments. This involves 'curl' and 'stretch' components and brood flushing that alters in distinct ways in response to developmental and environmental cues. However, a cost of active brood care in crustaceans is the susceptibility to embryo loss, this being further predisposed by the structure of the amphipod brood pouch. We found embryo retrieval by females of the rock-pool amphipod Apherusa jurinei, whereby females inserted experimentally offered embryos into their brood pouches. Females early in brood development retrieved embryos to a greater degree than both nonovigerous and later stage females. In this experiment, all offered embryos were from other females, indicating a motivation to retrieve embryos that often overrides any kin recognition. In a second experiment, we found kin discrimination, with both early stage and late stage females retrieving more of their own embryos than those from other females. Recognition was not simply of embryos of similar developmental stages. There were high levels of embryo cannibalism in both experiments, but females were significantly less likely to consume their own compared to foreign embryos. We thus further show that 'lower' crustaceans such as amphipods engage in elaborate active maternal care including kin recognition and discrimination. Their maternal behaviour appears to balance the costs and benefits of embryo retrieval, minimizing fitness reductions due to embryo loss and adoption of foreign embryos.

Communication, recognition and social work: Aligning the ethical theories of Habermas and Honneth

The modern world is replete with ethical challenges of Orwellian proportions. The violation of human rights and misrecognition of identities are two of the most pressing examples. In this paper, the ethical theories of Habermas and Honneth are aligned as a way of addressing these specific challenges within social work. It is suggested that these theories are complementary, mutually rectifying and concordant at the meta-ethical level of analysis. The alignment is also justified, pargmatically, through the construction of three hypothetical vignettes demonstrating different kinds of practice dilemmas. The need for egalitarian communication and the imperative to recognise human identity in all its dimensions subsequently emerge as the two foundation stones for ethical deliberation in social work.

Beyond homo economicus: Recognition, self-realization and social work

This paper builds on Ferguson's important contribution to the debate on personalization in social work that appeared in the British Journal of Social Work in 2007. Whereas Ferguson approached the topic through the lens of political philosophy, the account below draws on critical social theory to examine not only the nature of personalization, but also its supportive pillar of individualization. In particular, Axel Honneth's critique of individualization in modern society is presented before setting out his ideas on the need for self-realization through inter-subjective recognition. The implications of Honneth's position are then considered in terms of four interrelated dimensions of social work practice, namely: (i) social work as symbolic interaction; (ii) social work as care; (iii) social work as respect; and (iv) social work as validation. It is argued that this constellation of practices poses a direct and necessary challenge to a social work of personalization.

Identification of residues important for agonist recognition and activation in GPR40

GPR40 was formerly an orphan G protein-coupled receptor whose endogenous ligands have recently been identified as free fatty acids (FFAs). The receptor, now named FFA receptor 1, has been implicated in the pathophysiology of type 2 diabetes and is a drug target because of its role in FFA-mediated enhancement of glucose-stimulated insulin release. Guided by molecular modeling, we investigated the molecular determinants contributing to binding of linoleic acid, a C18 polyunsaturated FFA, and GW9508, a synthetic small molecule agonist. Twelve residues within the putative GPR40-binding pocket including hydrophilic/positively charged, aromatic, and hydrophobic residues were identified and were subjected to site-directed mutagenesis. Our results suggest that linoleic acid and GW9508 are anchored on their carboxylate groups by Arg183, Asn244, and Arg258. Moreover, His86, Tyr91, and His137 may contribute to aromatic and/or hydrophobic interactions with GW9508 that are not present, or relatively weak, with linoleic acid. The anchor residues, as well as the residues Tyr12, Tyr91, His137, and Leu186, appear to be important for receptor activation also. Interestingly, His137 and particularly His86 may interact with GW9508 in a manner dependent on its protonation status. The greater number of putative interactions between GPR40 and GW9508 compared with linoleic acid may explain the higher potency of GW9508.

Inter-Frame Contextual Modelling For Visual Speech Recognition

In this paper, we present a new approach to visual speech recognition which improves contextual modelling by combining Inter-Frame Dependent and Hidden Markov Models. This approach captures contextual information in visual speech that may be lost using a Hidden Markov Model alone. We apply contextual modelling to a large speaker independent isolated digit recognition task, and compare our approach to two commonly adopted feature based techniques for incorporating speech dynamics. Results are presented from baseline feature based systems and the combined modelling technique. We illustrate that both of these techniques achieve similar levels of performance when used independently. However significant improvements in performance can be achieved through a combination of the two. In particular we report an improvement in excess of 17% relative Word Error Rate in comparison to our best baseline system.
