Tribe and state in Iran and Afghanistan: an Update

RéSUMéL’auteur reprend ici l’analyse de « la tribu et l’État en Iran et en Afghanistan » issue d’une conférence qu’il avait organisée en 1979. Il constate que les thèmes abordés à cette occasion sont toujours d’actualité compte tenu des bouleversements politiques et sociaux des trois dernières décennies consécutifs aux révolutions intervenues dans ces deux pays. S’il y a une résurgence du tribalisme, les formes et fonctions des « tribus » ont considérablement évolué. L’auteur réitère sa conclusion : « Si le tribalisme a ses défauts et ses limites, il n’apparaît nullement comme un anachronisme dans la mesure où il pourvoit à la sécurité de ses membres et leur assure une survie à long terme » dans le monde contemporain.ABSTRACTThe author reviews his analysis of ‘tribe and state in Iran and Afghanistan’ resulting from a conference he convened in 1979. He considers the continuing relevance of the themes discussed at the conference, given the shattering political and social changes over the intervening three decades, following revolutions in both countries. There has been a revival of tribalism, but at the same time considerable transformation of the forms and functions of ‘the tribes’. The author repeats his conclusion that ‘Tribalism has its faults and limitations, but its provision of social security and its long-term survival value should recommend it as no anachronism’ in the contemporary world

Middle and Late Bronze Age settlement on the South Downs: the case study of Black Patch

By integrating the corpus of existing knowledge with new information gained by applying geo-archaeological techniques as well as more traditional techniques to fresh archaeological investigations at Black Patch and elsewhere, the aims of the research are to look at the economy, social organization and ritual behaviour of life in the Middle and Late Bronze Age on the South Downs in the light of modern archaeological theory to consider the questions ‘Why were these areas chosen for settlement?’, ‘What caused their abandonment?’ and ‘What can we learn about the life of the people associated with the settlements?’. The combination of field walking, field survey and soil sampling has shown the presence of a Neolithic flint spread, woodland clearance and agriculture before and during the period of site settlement at Black Patch. The positioning of the Hut platforms and enclosures across existing lynchets, the modification of the existing field system, the establishment of a new one and the adoption of more intensive farming techniques (manuring, weeding and crop location and rotation) would imply a change of social order and the adoption of a sedentary lifestyle for some. The existence of centrally placed hearths in huts found at Black Patch brings into doubt the existing day/night life/death metaphor currently commonly used for this period. Structured deposition points to a society concerned with agricultural fertility. The abandonment of Black Patch identified by Drewett and the dearth of later dated artefacts, at about the same time as the abandonment of the only other positively identified Deverel-Rimbury site in the immediate area, Itford Hill, suggests another change of social order, with livestock becoming more important as the Downland area around Black Patch appears then to be used only by nomadic herders. Areas to the west of the River Ouse which had been settled earlier developed more complicated specialist production sites. These have yet to be found east of the River Ous

Microwave pyrolysis of Laminaria digitata to produce unique seaweed-derived bio-oils

Microwave pyrolysis has become an attractive form of processing technology to generate bio-oil, bio-char and syngas from different biomass feedstocks. In this study, microwave pyrolysis was performed on the UK native seaweed Laminaria digitata and its extract residue from a bio-refinery process. Pyrolysis of these two feedstocks was successfully achieved without the requirement of microwave susceptors, as pelletizing the biomass was sufficient to allow microwave pyrolysis to occur. It was found that average energy requirements as low as 1.84–2.83 kJ g−1 were required to pyrolyse 55–70% of both feedstocks and bio-oil yields of 5–8% and 10–14% for native and extraction residue L. digitata were produced, respectively. Maximum microwave pyrolysis processing times were in the order of 200 s. The bio-oil generated from both feedstocks contained no phenolic based compounds, but a greater number of nitrogen-containing compounds and compounds derived from macroalgal polysaccharides. Yields of certain compounds differed in bio-oils generated from the two L. digitata feedstocks, however it was observed that specific energy did not have a direct influence on bio-oil compound yield. Furthermore, the identification of a particular nitrogen-containing compound L-Proline, 1-methyl-5-oxo-, methylester is thought to be a unique product of microwave pyrolysis when carbon-based additives are avoided

Measurement of inclusive D*+- and associated dijet cross sections in photoproduction at HERA

Inclusive photoproduction of D*+- mesons has been measured for photon-proton centre-of-mass energies in the range 130 < W < 280 GeV and a photon virtuality Q^2 < 1 GeV^2. The data sample used corresponds to an integrated luminosity of 37 pb^-1. Total and differential cross sections as functions of the D* transverse momentum and pseudorapidity are presented in restricted kinematical regions and the data are compared with next-to-leading order (NLO) perturbative QCD calculations using the "massive charm" and "massless charm" schemes. The measured cross sections are generally above the NLO calculations, in particular in the forward (proton) direction. The large data sample also allows the study of dijet production associated with charm. A significant resolved as well as a direct photon component contribute to the cross section. Leading order QCD Monte Carlo calculations indicate that the resolved contribution arises from a significant charm component in the photon. A massive charm NLO parton level calculation yields lower cross sections compared to the measured results in a kinematic region where the resolved photon contribution is significant.Comment: 32 pages including 6 figure

Measurement of Jet Shapes in Photoproduction at HERA

The shape of jets produced in quasi-real photon-proton collisions at centre-of-mass energies in the range $134-277$ GeV has been measured using the hadronic energy flow. The measurement was done with the ZEUS detector at HERA. Jets are identified using a cone algorithm in the $\eta - \phi$ plane with a cone radius of one unit. Measured jet shapes both in inclusive jet and dijet production with transverse energies $E^{jet}_T>14$ GeV are presented. The jet shape broadens as the jet pseudorapidity ($\eta^{jet}$) increases and narrows as $E^{jet}_T$ increases. In dijet photoproduction, the jet shapes have been measured separately for samples dominated by resolved and by direct processes. Leading-logarithm parton-shower Monte Carlo calculations of resolved and direct processes describe well the measured jet shapes except for the inclusive production of jets with high $\eta^{jet}$ and low $E^{jet}_T$. The observed broadening of the jet shape as $\eta^{jet}$ increases is consistent with the predicted increase in the fraction of final state gluon jets.Comment: 29 pages including 9 figure

Quality of life after sleeve gastrectomy and adjustable gastric banding

Abstract Background: With the addition of laparoscopic vertical sleeve gastrectomy (SG) to the bariatric surgery procedural toolkit, patients desiring a restrictive bariatric procedure often choose between adjustable gastric banding (LAGB) and SG. One study compared quality of life after these 2 procedures and found no difference. The purpose of our study was to re-evaluate the postoperative quality of life in LAGB and SG patients at a military teaching hospital in the United States. Methods: A retrospective review of 108 consecutive laparoscopic restrictive bariatric procedures performed within 15 months at a Department of Defense hospital was conducted. Of these 108 patients, 69 had undergone laparoscopic vertical SG and 39 LAGB. A validated quality of life questionnaire (Bariatric Quality of Life) was conducted a mean of 9.3 Ϯ 3.2 months (range 5-16) postoperatively. The weight loss and standard laboratory parameters were measured at 0, 1, 3, 6, and 12 months. Results: The quality of life assessment revealed significantly better scores after SG than after LAGB (66.5 versus 57.9, P ϭ .0002). The excess weight loss and excess body mass index loss at 3, 6, and 12 months postoperatively were significantly greater in the laparoscopic SG group. The patients demonstrated a clear preference over time for SG once it was offered. Conclusion: Early postoperative quality of life was superior after SG than after LAGB. SG also resulted in superior early excess weight loss. In a practice not constrained by reimbursement, these findings were associated with increased patient choice of SG after it began to be offered.

“At ‘Amen Meals’ It’s Me and God” Religion and Gender: A New Jewish Women’s Ritual

New ritual practices performed by Jewish women can serve as test cases for an examination of the phenomenon of the creation of religious rituals by women. These food-related rituals, which have been termed ‘‘amen meals’’ were developed in Israel beginning in the year 2000 and subsequently spread to Jewish women in Europe and the United States. This study employs a qualitative-ethnographic methodology grounded in participant-observation and in-depth interviews to describe these nonobligatory, extra-halakhic rituals. What makes these rituals stand out is the women’s sense that through these rituals they experience a direct con- nection to God and, thus, can change reality, i.e., bring about jobs, marriages, children, health, and salvation for friends and loved ones. The ‘‘amen’’ rituals also create an open, inclusive woman’s space imbued with strong spiritual–emotional energies that counter the women’s religious marginality. Finally, the purposes and functions of these rituals, including identity building and displays of cultural capital, are considered within a theoretical framework that views ‘‘doing gender’’ and ‘‘doing religion’’ as an integrated experience

The SNP rs6500843 in 16p13.3 is associated with survival specifically among chemotherapy-treated breast cancer patients

We have utilized a two-stage study design to search for SNPs associated with the survival of breast cancer patients treated with adjuvant chemotherapy. Our initial GWS data set consisted of 805 Finnish breast cancer cases (360 treated with adjuvant chemotherapy). The top 39 SNPs from this stage were analyzed in three independent data sets: iCOGS (n=6720 chemotherapy-treated cases), SUCCESS-A (n=3596), and POSH (n=518). Two SNPs were successfully validated: rs6500843 (any chemotherapy; per-allele HR 1.16, 95% C.I. 1.08-1.26, p=0.0001, p((adjusted))=0.0091), and rs11155012 (anthracycline therapy; per-allele HR 1.21, 95% C.I. 1.08-1.35, p=0.0010, p((adjusted))=0.0270). The SNP rs6500843 was found to specifically interact with adjuvant chemotherapy, independently of standard prognostic markers (p((interaction))=0.0009), with the rs6500843-GG genotype corresponding to the highest hazard among chemotherapy-treated cases (HR 1.47, 95% C.I. 1.20-1.80). Upon trans-eQTL analysis of public microarray data, the rs6500843 locus was found to associate with the expression of a group of genes involved in cell cycle control, notably AURKA, the expression of which also exhibited differential prognostic value between chemotherapy-treated and untreated cases in our analysis of microarray data. Based on previously published information, we propose that the eQTL genes may be connected to the rs6500843 locus via a RBFOX1-FOXM1 -mediated regulatory pathway.Peer reviewe

Inherited variation in immune genes and pathways and glioblastoma risk

To determine whether inherited variations in immune function single-nucleotide polymorphisms (SNPs), genes or pathways affect glioblastoma risk, we analyzed data from recent genome-wide association studies in conjunction with predefined immune function genes and pathways. Gene and pathway analyses were conducted on two independent data sets using 6629 SNPs in 911 genes on 17 immune pathways from 525 glioblastoma cases and 602 controls from the University of California, San Francisco (UCSF) and a subset of 6029 SNPs in 893 genes from 531 cases and 1782 controls from MD Anderson (MDA). To further assess consistency of SNP-level associations, we also compared data from the UK (266 cases and 2482 controls) and the Mayo Clinic (114 cases and 111 controls). Although three correlated epidermal growth factor receptor (EGFR) SNPs were consistently associated with glioblastoma in all four data sets (Mantel–Haenzel P values = 1 × 10−5 to 4 × 10−3), independent replication is required as genome-wide significance was not attained. In gene-level analyses, eight immune function genes were significantly (minP < 0.05) associated with glioblastoma; the IL-2RA (CD25) cytokine gene had the smallest minP values in both UCSF (minP = 0.01) and MDA (minP = 0.001) data sets. The IL-2RA receptor is found on the surface of regulatory T cells potentially contributing to immunosuppression characteristic of the glioblastoma microenvironment. In pathway correlation analyses, cytokine signaling and adhesion–extravasation–migration pathways showed similar associations with glioblastoma risk in both MDA and UCSF data sets. Our findings represent the first systematic description of immune genes and pathways that characterize glioblastoma risk
