Early modern Ireland and the history of the child

Analysis of public policy on the care of children and youth in nineteenth- and twentieth-century Ireland has generated a substantial historiography in recent years. By contrast there has been far less exploration of the state's attitude to young people in early modern Irish society. The historical dimension to the current debate on state care of minors is usually identified as beginning in the nineteenth century but the institutional custody of children originated in the sixteenth century. A central aim of this essay is to document the early modern context of public concern with children and youth in order to provide a more precise historical dimension to the contemporary debate.

The Ectocarpus genome and the independent evolution of multicellularity in brown algae

Brown algae (Phaeophyceae) are complex photosynthetic organisms with a very different evolutionary history to green plants, to which they are only distantly related(1). These seaweeds are the dominant species in rocky coastal ecosystems and they exhibit many interesting adaptations to these, often harsh, environments. Brown algae are also one of only a small number of eukaryotic lineages that have evolved complex multicellularity (Fig. 1). We report the 214 million base pair (Mbp) genome sequence of the filamentous seaweed Ectocarpus siliculosus (Dillwyn) Lyngbye, a model organism for brown algae(2-5), closely related to the kelps(6,7) (Fig. 1). Genome features such as the presence of an extended set of light-harvesting and pigment biosynthesis genes and new metabolic processes such as halide metabolism help explain the ability of this organism to cope with the highly variable tidal environment. The evolution of multicellularity in this lineage is correlated with the presence of a rich array of signal transduction genes. Of particular interest is the presence of a family of receptor kinases, as the independent evolution of related molecules has been linked with the emergence of multicellularity in both the animal and green plant lineages. The Ectocarpus genome sequence represents an important step towards developing this organism as a model species, providing the possibility to combine genomic and genetic(2) approaches to explore these and other(4,5) aspects of brown algal biology further.

SOCS2 regulates T helper type 2 differentiation and the generation of type 2 allergic responses

The incidence of allergy and asthma in developed countries is on the increase and this trend looks likely to continue. CD4(+) T helper 2 (Th2) cells are major drivers of these diseases and their commitment is controlled by cytokines such as interleukin 4, which are in turn regulated by the suppressor of cytokine signaling (SOCS) proteins. We report that SOCS2(-/-) CD4(+) T cells show markedly enhanced Th2 differentiation. SOCS2(-/-) mice, as well as RAG1(-/-) mice transferred with SOCS2(-/-) CD4(+) T cells, exhibit elevated type 2 responses after helminth antigen challenge. Moreover, in in vivo models of atopic dermatitis and allergen-induced airway inflammation, SOCS2(-/-) mice show significantly elevated IgE, eosinophilia, type 2 responses, and inflammatory pathology relative to wild-type mice. Finally, after T cell activation, markedly enhanced STAT6 and STAT5 phosphorylation is observed in SOCS2(-/-) T cells, whereas STAT3 phosphorylation is blunted. Thus, we provide the first evidence that SOCS2 plays an important role in regulating Th2 cell expansion and development of the type 2 allergic responses.

Improvising (Il)legality: Justice and the Irish Diaspora, NYC, 1930-32

The Seabury Commission, 1930-32, probed allegations of corruption made against, amongst others, the Irish-American Mayor of New York City, James J. ‘Jimmy’ Walker, and the Irish-dominated Tammany Hall, the Democratic political machine that had supported Walker. Taking the Seabury inquiry as its focus, this article explores these allegations from the perspective of Critical Studies in Improvisation (C.S.I.) fused with postcolonial critique. Improvisation, in accordance with C.S.I. principles, is not a lawless or extempore event; it is, instead, lawful, or full of law. The laws of improvisation may appear impenetrable to those unfamiliar with the practice. However, when read through a hibernocentric postcolonial perspective, their meaning and form become more understandable. As will be argued in this article, diasporic communities are inherently improvisatory; that is, they utilise improvisational techniques to help adapt and respond to new situations and social contexts. To be queried is whether the law and politics practiced by Tammany and Walker, taken together, constituted a markedly Irish approach to justice, one that entailed not scripted or planned illegality, as was alleged by Judge Seabury, but improvisations on Anglo-Protestant law as a response to the displacement of and discrimination against the Irish Diaspora in early twentieth century America.
