Policing gender mobilities: interrogating the âfeminisation of migrationâ to Europe
This article proposes a gendered critique of the European Neighbourhood Policy, a framework that, amongst other things, aims to facilitate the mobility of migrants to the EU from the bordering countries. We highlight the ambivalences of European gender and migration regimes, and we take issue with the celebration of the âfeminisation of migrationâ. The former fails to offer opportunities to women to safely embark on autonomous migratory projects, the latter contributes to reproduce traditional gender biases in the countries of origin as well as of destination. We conclude by suggesting that the EU critique to emigration countries for failing to tackle womenâs discrimination is less than persuasive when assessed vis-ĂĄ-vis with the curtailment on womenâs independent mobility across European borders
Iron Behaving Badly: Inappropriate Iron Chelation as a Major Contributor to the Aetiology of Vascular and Other Progressive Inflammatory and Degenerative Diseases
The production of peroxide and superoxide is an inevitable consequence of
aerobic metabolism, and while these particular "reactive oxygen species" (ROSs)
can exhibit a number of biological effects, they are not of themselves
excessively reactive and thus they are not especially damaging at physiological
concentrations. However, their reactions with poorly liganded iron species can
lead to the catalytic production of the very reactive and dangerous hydroxyl
radical, which is exceptionally damaging, and a major cause of chronic
inflammation. We review the considerable and wide-ranging evidence for the
involvement of this combination of (su)peroxide and poorly liganded iron in a
large number of physiological and indeed pathological processes and
inflammatory disorders, especially those involving the progressive degradation
of cellular and organismal performance. These diseases share a great many
similarities and thus might be considered to have a common cause (i.e.
iron-catalysed free radical and especially hydroxyl radical generation). The
studies reviewed include those focused on a series of cardiovascular, metabolic
and neurological diseases, where iron can be found at the sites of plaques and
lesions, as well as studies showing the significance of iron to aging and
longevity. The effective chelation of iron by natural or synthetic ligands is
thus of major physiological (and potentially therapeutic) importance. As
systems properties, we need to recognise that physiological observables have
multiple molecular causes, and studying them in isolation leads to inconsistent
patterns of apparent causality when it is the simultaneous combination of
multiple factors that is responsible. This explains, for instance, the
decidedly mixed effects of antioxidants that have been observed, etc...Comment: 159 pages, including 9 Figs and 2184 reference
AGRICULTURE AND BIOLOGY JOURNAL OF NORTH AMERICA Biology of Ceroplastes rusci L. (Coccoidea: Lecanidae) on fig tree, Ficus carica L. in the area of Médéa (Algeria)
ABSTRACT The biology of C.rusci was studied during an annual cycle on fig tree (Ficus carica) in the area of Médéa (Algeria). This species expresses two generations autumnal and spring. The hivernation is carried out at the stage young female with which they are associated the larvae with the second stage females
