Precarious Motherhood
No full textPrecarious Motherhood explores the experiences of racially minoritised mothers living with insecure immigration status and financial hardship in London, UK. It exposes the impact of hostile immigration policies and precarity on mothers’ interpersonal relationships and access to support. The author draws attention to how mothers manage the constraints they face and enact belonging. She then explores the impact on mothers’ couple relationships, friendships, adult kin relationships and faith-based networks. The book underlines the vital role of personal relationships in providing access to resources and support, but also demonstrates how precariously positioned mothers must carefully navigate relational tensions in their everyday lives. It highlights how social infrastructure facilitates relational practices, helping mothers to sustain their children’s wellbeing and their own.
Praise for Precarious Motherhood
'Rachel Benchekroun shows how mothers living without citizenship in a migrant community in Britain navigate kin networks to guard against immigration policies designed to undermine their social connections...This book deftly analyses alternative avenues to community well-being in a context of state violence.'
Ruth Gomberg, Critical Urban Anthropology Association
'This beautifully written and meticulously researched ethnography captures vividly and with deep humanity the richness and complexities of migrant mothers’ lives as they navigate the violence of hostile immigration policies. Profoundly social, intimate and relational yet never losing sight of powerful exclusionary structures, Precarious Motherhood is accessible, thoughtful and illuminating.'
Cecilia Menjívar, University of California, Los Angeles
'Precarious Motherhood brilliantly captures the resilience of migrant mothers as they engage in ""strategic mothering"" – crafting networks of care and belonging against the backdrop of hostile immigration policies.'
Jessica Potter, Patients Not Passports Campaign
'In this book, drawing on the powerful narratives of 22 mothers, Rachel Benchekroun offers a searing analysis of the reality of being a migrant without recourse to public funds in twenty-first century Britain.'
Louise Ryan, London Metropolitan University
'This invaluable research show how hostile environment policies, high fees and prolonged temporary immigration status have damaged the lives of migrant mothers and their children.'

PLASMA ACTH PRECURSORS (PRO-OPIOMELANOCORTIN AND PRO-ADRENOCORTICOTEROPIN) IN CATS WITH HYPERADRENOCORTICISM
No full textFeline hyperadrenocorticism (FH) is a rare condition. Pituitary-dependant hyperadrenocorticism (PDH) is observed in approximately 80% of cases. Most of the cases are associated with diabetes mellitus. Diagnosis of FH is quite difficult. First, clinical signs are non specific, except for the non systematic feline skin fragility syndrome. Secondly, the specificity of all tests validated for cats is questionable as well. Recently, an ACTH precursor (POMC/pro-ACTH) assay has been validated in cats (Benchekroun et al. , Proc Am Coll Vet Intern Med (ACVIM) Forum 2008). The aim of this preliminary study is to evaluate prospectively the plasma concentration of ACTH precursors in a small cohort of cats with PDH and estimate its usefulness in its diagnosis.
Three groups of cats were defined. Group 1 included cats with PDH. The diagnosis of FH was based on clinical data and low-dose dexamethasone suppression test (LDDST). PDH was demonstrated by adrenal and pituitary gland CT scan. Group 2 and 3 included diabetic and apparently healthy cats respectively. For the two groups, FH was excluded by LDDST or Urine Cortisol:Creatinine Ratio (UCCR).
Whole blood was collected from the cats on EDTA-tubes; after immediate centrifugation at 4°C, plasma was promptly frozen (-80°C) until assay.
Six cats were included in group 1. 5 cats had a large pituitary tumor with a height ranging from 6 mm to 27 mm. No pituitary tumor was visualised in the remaining cat. Plasma ACTH precursor concentrations ranging from 132 to 1412 pmol/L were measured in PDH cats with large tumors; the remaining cat of group 1 had an ACTH precursor concentration <26 pmol/L. Group 2 and 3 included 8 and 13 cats respectively. Plasma ACTH precursors ranged respectively from <26 to 96 pmol/L and from <26 to 99 pmol/L.
Although being found in a small number of cats, these results suggest that large corticotropic tumors are associated in that species with large plasma concentration of ACTH precursors like in dogs. No plasma POMC/pro-ACTH concentration above 100 pmol/L was found in cats free of PDH. The specificity of high plasma ACTH precursor concentration in cats with PDH has to be confirmed on a larger cohort. If confirmed, given the high prevalence of large pituitary tumors, the introduction of this tool could offer a gain of specificity in the general approach of feline PDH

NONRENEWABLE RESOURCE OLIGOPOLIES AND THE CARTEL-FRINGE GAME
No full textWe specify and solve a closed-loop dominant firm nonrenewable resource game, with a price-taking fringe. We show that (i) the outcomes of the closed-loop and the open-loop dominant firm nonrenewable resource game (a la Salant 1976) coincide and (ii) when the number of fringe firms becomes arbitrarily large, the equilibrium outcome of the closed-loop oligopoly game does not coincide with the equilibrium outcome of the closed-loop dominant firm nonrenewable resource game. Thus, the interpretation of the dominant firm model, where the fringe is assumed from the outset to be the price-taker, as a limit case of an asymmetric oligopoly where the number of fringe firms tends to infinity, does not extend to the case where firms can use closed-loop strategies.
Lean manufacturing in the valve pre-assembly area of a bottling lines production plant: An Italian case study
No full textThis paper describes a case study on lean manufacturing implementation to the valve pre-assembly area of a bottling lines production plant in Italy, and it is a pilot project for a wider lean implementation in the whole organization, with the aim of rationalizing all processes and improving efficiency. The case study was deeply described, justifying the implementation of lean in an area of an Engineer-To-Order (ETO) company. Despite the context, lean led to significant improvement in throughput rates (+50%), average lead times (-80%) and products quality. Also, the pilot assembly plant greatly decreased the occupied space on the shop floor. For all these reasons, lean is also confirmed as a strategic choice in ETO companies, where this philosophy can lead to a new way of thinking and working towards successful and long-lasting results

No full textDérivation urinaire cutanée continente par modification de la valve hydraulique iléale de Benchekroun ( technique et résultats à propos de 26 cas)
No full textNous rapportons ici notre expérience concernant la prise en charge de troubles vésico-sphinctériens invalidants nécessitant une dérivation urinaire cutanée continente. La valve hydraulique continente utilise un segment iléal selon la technique de BENCHEKROUN modifiée par MEZIANE puis par notre équipe. Entre 1997 et 2007, 26 patients (14 femmes et 12 hommes) en ont bénéficié. 18 patients présentaient des troubles vésico sphinctériens en rapport avec une vessie neurologique. 11 patients paraplégiques et 7 tétraplégiques. 8 patients présentaient des troubles vésico sphinctériens d étiologies diverses (sténoses urétrales récidivantes, néoplasie uro-génitale).L âge moyen au moment de l intervention était de 42 ans (21-75). Le délai moyen entre le début des troubles et l intervention était de 8 ans (1-31). Les données pré-opératoires (indication opératoire, état de dépendance motrice pour les neurologiques, mode de drainage vésical, bilan uro-dynamique, fonction rénale), per-opératoires (durée et type d intervention), et post-opératoires (complications précoces et tardives, recul et suivi) ont été rapportées. La qualité de vie a été évaluée par le questionnaire QUALIVEEN avant et après l intervention. La valve est parfaitement continente dans 87.5% des cas. Les auto-sondages sont acquis pour 25 patients (96%), 4 à 6 fois par jour, avec des sondes de calibre 18CH pour des volumes de 500ml en moyenne. Il existe une disparition ou une diminution de l hyperactivité vésicale urodynamique. Les complications précoces (< 3 mois) sont représentées par des infections urinaires (8%), des difficultés d apprentissages d auto sondage (7%), une occlusion intestinale (4%). Les complications tardives sont représentées par des sténoses anastomotiques urétéro néo-vésicales sur une vessie de remplacement dans 8% des cas ayant nécessité une reprise chirurgicale, des fuites occasionnelles à l effort au niveau de la valve (8%). La qualité de vie était significativement améliorée dans 86% des cas. La dérivation urinaire continente répond à la demande des patients qui en attendent un gain d autonomie, une amélioration de leur qualité de vie et une préservation de leur intimité. Le tout avec un taux de complications limitées. Néanmoins les indications restent limitées, la lourdeur de la chirurgie entraîne une modification du schéma corporel et nécessite une information précise et une prise charge globale et multidisciplinaire du patient avant de retenir l indicationAMIENS-BU Santé (800212102) / SudocPARIS-BIUM (751062103) / SudocSudocFranceF

Emission taxation, green innovations and inverted-U aggregate R&D efforts in a linear state oligopoly game
No full textWe revisit the well known differential Cournot game with polluting emissions dating back to Benchekroun and Long (1998), proposing a version of the model in which environmental taxation is levied on emissions rather than the environmental damage. This allows to attain strong time consistency under open-loop information, and yields two main results which can be summarized as follows: (i) to attain a fully green technology in steady state, the regulator may equivalently adopt an appropriate tax rate (for any given number of firms) or regulate market access (for any given tax rate); (ii) if the environmental damage depends on emissions only (i.e., not on industry output) then the aggregate green R&D effort takes an inverted-U shape, in accordance with Aghion et al. (2005), and the industry structure maximising aggregate green innovation also minimises individual and aggregate emissions
