‘Wives of the Gods’: debating Fiasidi and the politics of meaning

In the south-eastern Volta Region of Ghana, a form of female religious affiliation to local shrines commonly known as trokosi, has been the subject of a campaign consisting of Christian-based NGOs and various government agencies that has successfully criminalised the practice and organised ‘liberations’ and rehabilitations of the initiates. Protagonists of the abolition campaign argue that trokosiwo are illegitimately initiated to specific shrines based on an offence committed by another lineage member, acting as a perpetual figure of restitution. They also argue that the practice constitutes a form of ‘female ritual slavery’ by translating the term trokosi as “slave of the gods” and arguing that the socio-economic status and social relations of the trokosiwo indicate their ‘slavery’. The highly publicised abolition campaign stimulated a counter-campaign, led by a neo-traditional organisation, that argued that the female shrine initiates are Queen-Mothers (rather than slaves), role-models to their lineage (rather than figures of restitution), and are socially privileged. Central to these contestations has been the figure of the fiasidi, particularly those initiated to shrines in one locality, Klikor. Abolitionists define fiasidiwo as being a variant of trokosi, despite some key differences. Those that contest this representation justified their position by highlighting the socio-economic position of fiasidiwo in Klikor's three shrines and pointing out the critical ways it differed from the representation of the Trokosi Slave. Members of the Klikor shrines also became political actors in the debates that ensued, by developing a close alliance to the neo-traditionalist organisation and creating their own organisation to network with similar shrines. This thesis considers the debates around trokosi and fiasidi at the national level and explores in detail the meaning attached to fiasidi and her position in the Klikor shrines and community. At its core, is an ethnography of the three shrines, their ritual specialists and initiates. I explore the way in which meaning is ascribed to the fiasidi, through narratives of the past, through the symbolism of key rituals and through the structured interactions between petitioners and ritual specialists. A concluding section then considers the intersection between these meanings and the contested terrains of religion in the debates about the Trokosi Slaves

Increases in ROPS Pricing from 2006-2012 and the Impact on ROPS Demand

In 2006, a social marketing campaign was developed to increase the installation of rollover protective structures (ROPS) on unprotected New York tractors. Using data gathered from the program\u27s hotline, the impact of price increases on farmers\u27 interest in ROPS is examined. Pricing data were obtained for all rigid ROPS kits commercially available in the U.S. since 2006. These data were stratified into two groups of ROPS suppliers: (1) tractor manufacturers that sell ROPS for their own tractors, referred to in this study as original equipment manufacturers (OEMs), and (2) aftermarket (AM) ROPS suppliers. The trend in price increases was contrasted with the change in the consumer price index (CPI), the probability of retrofitting within quintiles of cost was estimated, and the increase in ROPS prices over time was plotted The average price increase for a ROPS kit (excluding shipping and installation) over the six years of the study was 23.3% for OEM versus 60.5% for AM (p \u3c 0.0001). Out-of-pocket expenses held steady for OEM versus a six-year increase of $203 for AM (p = 0.098). The probability of a farmer retrofitting dropped monotonically from 66.9% in the lowest ROPS cost quintile to 23% in the highest. If these trends continue, the proportion of inquiries resulting in a ROPS retrofit will fall below 20% by 2020 for AM ROPS. Based on other trends identified in the literature, it is reasonable to assume that decreases in ROPS installation are likely to affect the tractor owners who are most likely to need these safety devices

Efficacy of salmeterol/fluticasone propionate by GOLD stage of chronic obstructive pulmonary disease: analysis from the randomised, placebo-controlled TORCH study

Background: The efficacy of inhaled salmeterol plus fluticasone propionate (SFC) in patients with severe or very severe COPD is well documented. However, there are only limited data about the influence of GOLD severity staging on the effectiveness of SFC, particularly in patients with milder disease. Methods: TORCH was a 3-year, double-blind, placebo-controlled trial of 6112 patients with moderate/severe COPD with pre-bronchodilator FEV1 < 60% predicted (mean age 65 years, 76% male, mean 44% predicted FEV1, 43% current smokers). To understand the relative efficacy of SFC and its components by GOLD stages, we conducted a post-hoc analysis of the TORCH dataset using baseline post-bronchodilator FEV1 to segment patients into three groups: moderate COPD (GOLD stage II and above: ³ 50%; n = 2156), severe COPD (GOLD stage III: 30% to < 50%; n = 3019) and very severe COPD (GOLD stage IV: < 30%; n = 937). Results: Compared with placebo, SFC improved post-bronchodilator FEV1: 101 ml (95% confidence interval [CI]: 71, 132) in GOLD stage II, 82 ml (95% CI: 60, 104) in GOLD stage III and 96 ml (95% CI: 54, 138) in GOLD stage IV patients, and reduced the rate of exacerbations: 31% (95% CI: 19, 40) in GOLD stage II, 26% (95% CI: 17, 34) in GOLD stage III and 14% (95% CI: -4,29) in GOLD stage IV. SFC improved health status to a greater extent than other treatments regardless of baseline GOLD stage. Similarly, SFC reduced the risk of death by 33% (hazard ratio [HR] 0.67; 95% CI: 0.45, 0.98) for GOLD stage II, 5% (HR 0.95; 95% CI: 0.73, 1.24) for GOLD stage III, and 30% (HR 0.70; 95% CI: 0.47, 1.05) for GOLD stage IV. The rates of adverse events were similar across treatment arms and increased with disease severity. Overall, there was a higher incidence of pneumonia in the fluticasone propionate and SFC arms, compared with other treatments in all GOLD stages. Conclusion: In the TORCH study, SFC reduced moderate-to-severe exacerbations and improved health status and FEV1 across GOLD stages. Treatment with SFC may be associated with reduced mortality compared with placebo in patients with GOLD stage II disease. The effects were similar to those reported for the study as a whole. Thus, SFC is an effective treatment option for patients with GOLD stage II COPD

Stat5 Synergizes with T Cell Receptor/Antigen Stimulation in the Development of Lymphoblastic Lymphoma

Signal transducer and activator of transcription (STAT) proteins are latent transcription factors that mediate a wide range of actions induced by cytokines, interferons, and growth factors. We now report the development of thymic T cell lymphoblastic lymphomas in transgenic mice in which Stat5a or Stat5b is overexpressed within the lymphoid compartment. The rate of lymphoma induction was markedly enhanced by immunization or by the introduction of TCR transgenes. Remarkably, the Stat5 transgene potently induced development of CD8+ T cells, even in mice expressing a class II–restricted TCR transgene, with resulting CD8+ T cell lymphomas. These data demonstrate the oncogenic potential of dysregulated expression of a STAT protein that is not constitutively activated, and that TCR stimulation can contribute to this process

Colorectal cancer linkage on chromosomes 4q21, 8q13, 12q24, and 15q22

A substantial proportion of familial colorectal cancer (CRC) is not a consequence of known susceptibility loci, such as mismatch repair (MMR) genes, supporting the existence of additional loci. To identify novel CRC loci, we conducted a genome-wide linkage scan in 356 white families with no evidence of defective MMR (i.e., no loss of tumor expression of MMR proteins, no microsatellite instability (MSI)-high tumors, or no evidence of linkage to MMR genes). Families were ascertained via the Colon Cancer Family Registry multi-site NCI-supported consortium (Colon CFR), the City of Hope Comprehensive Cancer Center, and Memorial University of Newfoundland. A total of 1,612 individuals (average 5.0 per family including 2.2 affected) were genotyped using genome-wide single nucleotide polymorphism linkage arrays; parametric and non-parametric linkage analysis used MERLIN in a priori-defined family groups. Five lod scores greater than 3.0 were observed assuming heterogeneity. The greatest were among families with mean age of diagnosis less than 50 years at 4q21.1 (dominant HLOD = 4.51, α = 0.84, 145.40 cM, rs10518142) and among all families at 12q24.32 (dominant HLOD = 3.60, α = 0.48, 285.15 cM, rs952093). Among families with four or more affected individuals and among clinic-based families, a common peak was observed at 15q22.31 (101.40 cM, rs1477798; dominant HLOD = 3.07, α = 0.29; dominant HLOD = 3.03, α = 0.32, respectively). Analysis of families with only two affected individuals yielded a peak at 8q13.2 (recessive HLOD = 3.02, α = 0.51, 132.52 cM, rs1319036). These previously unreported linkage peaks demonstrate the continued utility of family-based data in complex traits and suggest that new CRC risk alleles remain to be elucidated. © 2012 Cicek et al

Synaptotagmin‐7 enhances calcium‐sensing of chromaffin cell granules and slows discharge of granule cargos

Synaptotagmin‐7 (Syt‐7) is one of two major calcium sensors for exocytosis in adrenal chromaffin cells, the other being synaptotagmin‐1 (Syt‐1). Despite a broad appreciation for the importance of Syt‐7, questions remain as to its localization, function in mediating discharge of dense core granule cargos, and role in triggering release in response to physiological stimulation. These questions were addressed using two distinct experimental preparations—mouse chromaffin cells lacking endogenous Syt‐7 (KO cells) and a reconstituted system employing cell‐derived granules expressing either Syt‐7 or Syt‐1. First, using immunofluorescence imaging and subcellular fractionation, it is shown that Syt‐7 is widely distributed in organelles, including dense core granules. Total internal reflection fluorescence (TIRF) imaging demonstrates that the kinetics and probability of granule fusion in Syt‐7 KO cells stimulated by a native secretagogue, acetylcholine, are markedly lower than in WT cells. When fusion is observed, fluorescent cargo proteins are discharged more rapidly when only Syt‐1 is available to facilitate release. To determine the extent to which the aforementioned results are attributable purely to Syt‐7, granules expressing only Syt‐7 or Syt‐1 were triggered to fuse on planar supported bilayers bearing plasma membrane SNARE proteins. Here, as in cells, Syt‐7 confers substantially greater calcium sensitivity to granule fusion than Syt‐1 and slows the rate at which cargos are released. Overall, this study demonstrates that by virtue of its high affinity for calcium and effects on fusion pore expansion, Syt‐7 plays a central role in regulating secretory output from adrenal chromaffin cells.Syt‐7 is a high‐affinity calcium sensor expressed on chromaffin cell dense core granules. The purpose of this study was to assess the role of Syt‐7 in regulating the secretory response to cholinergic stimulation. Acetylcholine elicits secretion by elevating cytosolic calcium. The calcium sensitivity of exocytosis in cells lacking Syt‐7 is impaired. Cells that lack Syt‐7 also release peptide hormones at faster rates, implicating a role for Syt‐7 in regulating the exocytotic fusion pore. These data demonstrate that Syt‐7 has an important role in triggering exocytosis in cells and is likely to play a role in controlling hormone output, in situ.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/162737/3/jnc14986.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/162737/2/jnc14986-sup-0001-Supinfo.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/162737/1/jnc14986_am.pd

Assistants, Guides, Collaborators, Friends: The Concealed Figures of Conflict Research

Recent scholarship has demonstrated an increasing awareness of the need for more grounded, empirical research into the micro-level dynamics of violent contexts. Research in these difficult, dangerous, and potentially violent conflict or post-conflict settings necessitates the formation of new relationships of dependency, and assistants, friends, collaborators, and guides become central figures in the field. However, all too often, these figures are written out of academic accounts and silenced in our analyses. This not only does them a significant disservice, but it also obscures potential biases, complexities, and ethical dilemmas that emerge in the way in which such research is carried out. Drawing upon fieldwork exploring the 2007–2008 Kenyan postelection violence, this paper argues that reliance upon insider-assistants is essential in conflict settings and explores the challenges inherent in these relationships. As researchers become increasingly engaged in micro-level studies of violent contexts, we must interrogate the realities of how our knowledge has been produced and engage in more open and honest discussions of the methodological and ethical challenges of conflict research
