The 'Parekh Report' - national identities with nations and nationalism

‘Multiculturalists’ often advocate national identities. Yet few study the ways in which ‘multiculturalists’ do so and in this article I will help to fill this gap. I will show that the Commission for Multi-Ethnic Britain’s report reflects a previously unnoticed way of thinking about the nature and worth of national identities that the Commission’s chair, and prominent political theorist, Bhikhu Parekh, had been developing since the 1970s. This way of thinking will be shown to avoid the questionable ways in which conservative and liberal nationalists discuss the nature and worth of national identities while offering an alternative way to do so. I will thus show that a report that was once criticised for the way it discussed national identities reflects how ‘multiculturalists’ think about national identities in a distinct and valuable way that has gone unrecognised

"Oh! What a tangled web we weave": Englishness, communicative leisure, identity work and the cultural web of the English folk morris dance scene

In this paper, we consider the relationship between Englishness and the English folk morris dance scene, considering how the latter draws from and reinforces the former. Englishness is considered within the context of the cultural web; a tool more often applied to business management but linked to a sociological viewpoint here. By doing so, we draw the connections between this structured business model and the cultural identity of Englishness. Then, we use the framework of the cultural web and theories of leisure, culture and identity to understand how morris dancers see their role as dancers and ‘communicative leisure’ agents in consciously defending Englishness, English traditions and inventions, the practices and traditions of folk and morris, and the various symbolic communities they inhabit. We argue that most morris dancers in our research become and maintain their leisured identities as dancers because they are attracted to the idea of tradition – even if that tradition is invented and open to change

Social organization of the Tajiks of Andarab Valley, Afghanistan

The thesis is a description of the social organization of the Persian-speaking peasantry and part-pastoralists of a highland district in the central Hindu Kush of Afghanistan. Andarab district, with an estimated population of 33,000 souls, constitutes a geographical as well as governmental entity, and, as the people are orthodox Muslims, it is also a small segment of the cosmopolitan Islamic fraternity. The thesis falls into two parts, which are separated by a statement of the methods of fieldwork (Chapter III) employed in the prevailing political and local circumstances. The first part (Chapter II) attempts a comprehensive report of Adarab. After an account of the geographical, ecological and demographic background, it describes the division of the population into individual autocephalous households, either simple or polygynous, and grouped into village communities on the basis of patrilocal domicile. The factors of socio-economic stratification are specified. An examination of the boundaries of the four "electoral wards" into which Andarab is divided, suggests that a system of competitive oppositions is the main theme in political activity. The second part of the thesis presents exploratory material on the local community, the Afghan state, and Islam. Chapter IV suggests that, in the absence of corporate estates and succession by descent, the dynamic of the individual's life-career in his local community derives from the cycle of domestic development and his position vis-a-vis his coparceners as well as other kin relations. The Koranic rules of marriage and inheritance are given, and followed by an examination of their characteristic patterns among clusters of close collateral agnates, which are the only factional groups within the local community. An illustrative case of a matrilateral cross-cousin marriage within one village, shows that competitive opposition comes to a head over questions of marriage bestowal and bridewealth. Chapter V describes the system of local government; and the careers in Andarab of two successive deputy commissioners, with reference to their policies in dealing with the departmental personnel within the district secretariat, and also the circle of native intermediaries through whom the business of administration must be carried on. Chapter VI deals briefly with the rites through which the local community is integrated in to cosmopolitan Islam. The main element in these rites of Muslimhood is the congregational one, and the seclusion of women rigidly excludes them from participation in it. It is suggested that the function of purdah is to define the particularist side of local citizenship, while the communal and universalist side is enjoined on the men by the periodic congregational rites

Anisotropic clustering of inertial particles in homogeneous shear flow

Recently, clustering of inertial particles in turbulence has been thoroughly analyzed for statistically homogeneous isotropic flows. Phenomenologically, spatial homogeneity of particles configurations is broken by the advection of a range of eddies determined by the Stokes relaxation time of the particles which results in a multi-scale distribution of local concentrations and voids. Much less is known concerning anisotropic flows. Here, by addressing direct numerical simulations (DNS) of a statistically steady particle-laden homogeneous shear flow, we provide evidence that the mean shear preferentially orients particle patterns. By imprinting anisotropy on large scales velocity fluctuations, the shear indirectly affects the geometry of the clusters. Quantitative evaluation is provided by a purposely designed tool, the angular distribution function of particle pairs (ADF), which allows to address the anisotropy content of particles aggregates on a scale by scale basis. The data provide evidence that, depending on the Stokes relaxation time of the particles, anisotropic clustering may occur even in the range of scales where the carrier phase velocity field is already recovering isotropy. The strength of the singularity in the anisotropic component of the ADF quantifies the level of fine scale anisotropy, which may even reach values of more than 30% direction-dependent variation in the probability to find two close-by particles at viscous scale separation.Comment: To appear in Journal Fluid Mechanics 200

In vitro quantification of stent-graft behaviour during chimney thoracic endovascular aortic repair

Objective: To quantify dynamic gutter phenomena and endograft deformations during double chimney thoracic endovascular aortic repair (ch-TEVAR) in a physiological model of the thoracic aorta subjected to pulsatile haemodynamic conditions. Methods: Two in vitro procedures revascularizing the brachiocephalic trunk and left common carotid artery were performed representing both balloon-expandable (BE, Ankura-BeGraft) and self-expandable (SE, Ankura-Viabahn) double ch-TEVAR configurations. Retrospectively gated computed tomography (CT) was used to evaluate endograft behaviour. Device interactions were characterised according to gutter volume, gutter surface deviation, and endograft deformation (D-ratio) at end-diastolic and peak-systolic aortic pressure. Results: Use of BE chimney grafts resulted in three times total gutter volume compared to SE chimney grafts. Gutter volumes were observed to vary dynamically between the end-diastolic and peak-systolic phases of the cardiac cycle, with the most substantial change associated with the BE configuration. Chimney graft deformations were dependent on device type, with SE devices exhibiting up to twice the deformation as BE devices. When adjacent, SE chimney grafts were observed to support each other, and thus tended towards a more consistently circular shape. Conclusion: Gutter and chimney graft behaviour were dependent on device type, and exhibited both spatial and temporal variability. This study emphasises notable differences between BE and SE double ch-TEVAR configurations which should be considered when evaluating risk of endoleak. The findings reported here also support the use of gated CT to better identify device-related complications with ch-TEVAR, and can be used in the design of next generation devices

Diagnostic and therapeutic treatment modalities for acute lower gastrointestinal bleeding: a systematic review.

 Investigations for lower gastrointestinal bleeding (LGIB) include flexible sigmoidoscopy, colonoscopy, computed tomographic angiography (CTA), and angiography. All may be used to direct endoscopic, radiological or surgical treatment, although their optimal use is unknown. The aims of this study were to determine the diagnostic and therapeutic yields of endoscopy, CTA, and angiography for managing LGIB, and their influence on rebleeding, transfusion, and hospital stay. A systematic search of MEDLINE, PubMed, EMBASE, and CENTRAL was undertaken to identify randomized controlled trials (RCTs) and nonrandomized studies of intervention (NRSIs) published between 2000 and 12 November 2015 in patients hospitalized with LGIB. Separate meta-analyses were conducted, presented as pooled odds (ORs) or risk ratios (RR) with 95 % confidence intervals (CIs). Two RCTs and 13 NRSIs were included, none of which examined flexible sigmoidoscopy, or compared endotherapy with embolization, or investigated the timing of CTA or angiography. Two NRSIs (57 - 223 participants) comparing colonoscopy and CTA were of insufficient quality for synthesis but showed no difference in diagnostic yields between the two interventions. One RCT and 4 NRSIs (779 participants) compared early colonoscopy (< 24 hours) with colonoscopy performed later; meta-analysis of the NRSIs demonstrated higher diagnostic and therapeutic yields with early colonoscopy (OR 1.86, 95 %CI 1.12 to 2.86, P  = 0.004 and OR 3.08, 95 %CI 1.93 to 4.90, P  < 0.001, respectively) and reduced length of stay (mean difference 2.64 days, 95 %CI 1.54 to 3.73), but no difference in transfusion or rebleeding. In LGIB there is a paucity of high-quality evidence, although the limited studies on the timing of colonoscopy suggest increased rates of diagnosis and therapy with early colonoscopy

Meta-analysis of individual-patient data from EVAR-1, DREAM, OVER and ACE trials comparing outcomes of endovascular or open repair for abdominal aortic aneurysm over 5 years

Background: The erosion of the early mortality advantage of elective endovascular aneurysm repair (EVAR) compared with open repair of abdominal aortic aneurysm remains without a satisfactory explanation. Methods: An individual-patient data meta-analysis of four multicentre randomized trials of EVAR versus open repair was conducted to a prespecified analysis plan, reporting on mortality, aneurysm-related mortality and reintervention. Results: The analysis included 2783 patients, with 14 245 person-years of follow-up (median 5·5 years). Early (0–6 months after randomization) mortality was lower in the EVAR groups (46 of 1393 versus 73 of 1390 deaths; pooled hazard ratio 0·61, 95 per cent c.i. 0·42 to 0·89; P = 0·010), primarily because 30-day operative mortality was lower in the EVAR groups (16 deaths versus 40 for open repair; pooled odds ratio 0·40, 95 per cent c.i. 0·22 to 0·74). Later (within 3 years) the survival curves converged, remaining converged to 8 years. Beyond 3 years, aneurysm-related mortality was significantly higher in the EVAR groups (19 deaths versus 3 for open repair; pooled hazard ratio 5·16, 1·49 to 17·89; P = 0·010). Patients with moderate renal dysfunction or previous coronary artery disease had no early survival advantage under EVAR. Those with peripheral artery disease had lower mortality under open repair (39 deaths versus 62 for EVAR; P = 0·022) in the period from 6 months to 4 years after randomization. Conclusion: The early survival advantage in the EVAR group, and its subsequent erosion, were confirmed. Over 5 years, patients of marginal fitness had no early survival advantage from EVAR compared with open repair. Aneurysm-related mortality and patients with low ankle : brachial pressure index contributed to the erosion of the early survival advantage for the EVAR group. Trial registration numbers: EVAR-1, ISRCTN55703451; DREAM (Dutch Randomized Endovascular Aneurysm Management), NCT00421330; ACE (Anévrysme de l'aorte abdominale, Chirurgie versus Endoprothèse), NCT00224718; OVER (Open Versus Endovascular Repair Trial for Abdominal Aortic Aneurysms), NCT00094575

Interventional radiology procedures, facilities, and workforce across England and Wales: a snapshot retrospective evaluation from 2017 to 2021

Aims There is no comprehensive data collection outlining the numbers and types of interventional radiology (IR) procedures in the United Kingdom. Similarly, limited data are available on the IR facilities and workforce within the National Health Services (NHS) trusts. The purpose of this study is to evaluate the number/type of IR procedures, facilities, and workforces across England and Wales. Materials and Methods This retrospective study used the 2000 Freedom of Information Act to obtain information regarding the IR procedures performed in NHS trusts in England and Wales from 2017 to 2021. We collected additional information on IR workforce and facilities, including the number of IR consultants, nurses, trainees, and angiographic suites and day case units; analysed procedures by complexity; and performed data analysis by region. Results A total of 1,340,352 IR procedures were analysed. An increasing trend was observed in the number of IR procedures from 2017 to 2021 (p=0.07, R=0.93). There were more intermediate and complex procedures than simple ones (p=0.0001). Notable geographical variation was observed in terms of IR facilities including angiographic suites and day case units, and the number of IR consultants, nurses, and trainees. Conclusions The IR field continues to grow as evidenced by increasing trends in the number and complexity of the procedures over the years. There is an uneven IR workforce, services, and facilities distribution across England and Wales. Therefore, there is a crucial need for centralised data collection to evaluate and monitor interventions besides comprehensive revision of UK IR service provision

(Un)becoming women: Indian factory women's counternarratives of gender

This paper portrays the life stories of five factory workers in Delhi whose life trajectories run counter to normative femininity. As daughters and wives, they are neglected, abandoned or rejected by their families; they live alone, with their parents past the age that is their natal right, with siblings, or with families and men who are not related to them. I explore the circulation of their counternarratives and how their gender transgressions go public through ordinary forms of talk, such as gossip and rumor. I argue that their move out of the normative is not produced by, but produces, their gender politics; that their agency emerges cognitively from the telling of their stories in tandem with their interlocutors' credulity and uptake; and that the site of gender politics for working class Indian women lies in the informal subaltern publics that are formed by the circulation of their stories. Contrary to the notion of a stable unitary subject that precedes the political, these women's counternarratives demonstrate the subject‐in‐process as a political effect. Their alterity does not exist outside the heteronormative gender order but demarcates the boundaries of its historicity, hinting at both the internal contradictions of existing gender relations and their future possibilities.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/112196/1/j.1467-954X.2011.02026.x.pd
