Tilly's Technical Accounts and Standard Stories Explored in Financial Markets:The Case of the Istanbul Stock Exchange

In this article, I follow the lead opened up by Tilly (1999, 2002) who was interested in people's storytelling. I do so by looking at sense-making and the legitimacy narratives of market actors in the Istanbul Stock Exchange. Tilly (2006, 2008) himself walked the narrative path and investigated Why and how people give reasons and how people attribute Credit and Blame to other's actions. These books provide insights into people's storytelling in the everyday situations of the home, courtrooms, hospitals, and so on. Nevertheless, Tilly's faith in the prevalence of technical accounts as modes of explanation in intra and inter organisational settings, and superior stories as mode of communication between expert givers and non-specialized receivers, seems to ignore informational uncertainties, intra and inter organisational hierarchies and conflicts pertinent to organisations. It is these factors that push standard stories (Tilly, 1999) into the forefront at the expense of technical stories within the story exchanges of market actors. I demonstrate this by presenting a sample of story exchanges from the Istanbul Stock Exchange under situations of informational uncertainties and organisational conflicts

Demographic and microbial characteristics of extrapulmonary tuberculosis cases diagnosed in Malatya, Turkey, 2001-2007

<p>Abstract</p> <p>Background</p> <p>Extrapulmonary tuberculosis (EPTB) has an increasing rate in Turkey. The reason remains largely unknown. A better understanding of the demographic and microbial characteristics of EPTB in the Turkish population would extend the knowledgebase of EPTB and allow us to develop better strategies to control tuberculosis (TB).</p> <p><b>Methods</b></p> <p>We retrospectively evaluated clinical and laboratory data of 397 bacteriologically-confirmed TB cases diagnosed during an eight year-period using by chi-square analysis and multivariate logistic regression model.</p> <p>Results</p> <p>Of the 397 study patients, 103 (25.9%) had EPTB and 294 (74.1%) had pulmonary tuberculosis (PTB). The most commonly seen two types of EPTB were genitourinary TB (27.2%) and meningeal TB (19.4%). TB in bone/joints, pleural cavity, lymph nodes, skin, and peritoneal cavity occurred at a frequency ranging from 9.7% to 10.7%. The age distribution was significantly different (P < 0.01) between PTB and EPTB, with patients older than 45 years tending to have an increased risk of EPTB. Furthermore, the distribution of different types of EPTB differed significantly among age groups (P = 0.03). Meningeal and bone and/or joint TB were more commonly observed among the male patients, while lymphatic, genitourinary, and peritoneal TB cases were more frequently seen among females. Unique strain infection was statistically significantly associated with EPTB (OR: 2.82, 95% CI [1.59, 5.00])</p> <p>Conclusions</p> <p>EPTB accounted for a significant proportion of TB cases in Malatya, Turkey between 2001 and 2007. The current study has provided an insight into the dynamics of EPTB in Malatya, Turkey. However, the risk factors for having EPTB in Malatya, Turkey remain to be assessed in future studies using population-based or randomly selected sample.</p

Altered Metabolism and Persistent Starvation Behaviors Caused by Reduced AMPK Function in Drosophila

Organisms must utilize multiple mechanisms to maintain energetic homeostasis in the face of limited nutrient availability. One mechanism involves activation of the heterotrimeric AMP-activated protein kinase (AMPK), a cell-autonomous sensor to energetic changes regulated by ATP to AMP ratios. We examined the phenotypic consequences of reduced AMPK function, both through RNAi knockdown of the gamma subunit (AMPKγ) and through expression of a dominant negative alpha (AMPKα) variant in Drosophila melanogaster. Reduced AMPK signaling leads to hypersensitivity to starvation conditions as measured by lifespan and locomotor activity. Locomotor levels in flies with reduced AMPK function were lower during unstressed conditions, but starvation-induced hyperactivity, an adaptive response to encourage foraging, was significantly higher than in wild type. Unexpectedly, total dietary intake was greater in animals with reduced AMPK function yet total triglyceride levels were lower. AMPK mutant animals displayed starvation-like lipid accumulation patterns in metabolically key liver-like cells, oenocytes, even under fed conditions, consistent with a persistent starved state. Measurements of O2 consumption reveal that metabolic rates are greater in animals with reduced AMPK function. Lastly, rapamycin treatment tempers the starvation sensitivity and lethality associated with reduced AMPK function. Collectively, these results are consistent with models that AMPK shifts energy usage away from expenditures into a conservation mode during nutrient-limited conditions at a cellular level. The highly conserved AMPK subunits throughout the Metazoa, suggest such findings may provide significant insight for pharmaceutical strategies to manipulate AMPK function in humans

Examination of the effect of melatonin use before hysterosalpingography on ovarian follicle reserve in rats

Objective: To examine the effects of lipiodol, melatonin, and radiation used during hysterosalpingography (HSG) on rat ovarian follicle reserve. Materials and Methods: A total of 50 Wistar rats with regular estrous cycles were randomly divided into five groups. Group 1 was the control group. The other groups, X-ray was applied (G2), 0.1 ml lipiodol was applied to each uterine horn (G3), 20 mg/kg intraperitoneal melatonin application was followed by 0.1 ml lipiodol administration to each uterine horn after 15 minutes (G4), 20 mg/kg melatonin was administered to ligamentum suspensorium ovarii, followed by 0.1 ml lipiodol application to each uterine horn after 15 minutes (G5), respectively. The rats in G2, G3, G4, and G5 were exposed three times to whole body radiation. Then, all rats were re-opened and left oophorectomy was performed. Left ovarian samples were fixed in formaldehyde. Primordial, primary, secondary, and tertiary follicles were counted in the preparations, and all were added to calculate the ovarian follicle reserve. Results: Primordial, primary, and ovarian follicle reserves were found significantly lower in G2, in comparison to other groups. Atretic follicle values were significantly higher in G2 compared to G3, and in G3 compared to the other groups. Regression of angiogenesis within corpus luteum was found significantly lower in G2, compared to G3, and in G3 compared to other groups. All values in G1, G4, and G5 were similar. Conclusion: Use of lipiodol and melatonin during HSG procedure prevents the negative effects of radiation on ovarian follicle reserve. © 2018 S.O.G. Canada Inc. All rights reserved

Examination of the antioxidant effects of pre-HSG melatonin use on ovarian surface epithelium in rats: An experimental study

PubMedID: 29952147Background. There is no study of whether the dysplastic changes in the ovarian surface epithelium of X-ray-exposed rats during hysterosalpingography (HSG) decrease or not with the use of Lipiodol and melatonin given both intraperitoneally (i.p.) and into the suspensorium ovarii. Objectives. We investigated the restorative effects of melatonin and Lipiodol administration during the HSG procedure on the dysplastic changes in the ovarian surface epithelium of X-ray-exposed rats. Material and methods. A total of 50 Wistar rats with regular estrous cycles were randomly divided into 5 groups. Group 1 was the control group. In other groups, X-ray was applied (group 2), 0.1 mL Lipiodol was applied to each uterine horn (group 3), 20 mg/kg intraperitoneal melatonin application was followed by 0.1 mL Lipiodol administration to each uterine horn after 15 min (group 4), and 20 mg/kg melatonin was administered to the ligamentum suspensorium ovarii, followed by 0.1 mL Lipiodol application to each uterine horn after 15 min (group 5). The rats in groups 2–5 were exposed to whole body radiation 3 times. After 3 h, the abdomens of all rats were reopened and left oophorectomy was performed. Results. The presence of nucleoli and mitosis values were found similar among the groups. All other parameters were significantly higher in group 2 compared to other groups, except for the presence of nucleoli and mitosis values (p < 0.05). The presence of hyperchromasia and the total score were found to be the highest in group 2, followed by group 3, when compared to other groups (p < 0.05). It was detected that the detrimental effects of X-ray exposure diminished with Lipiodol use, and were further reduced by the use of melatonin in combination. Conclusions. We suggest that the use of melatonin and Lipiodol during HSG may prevent the carcinogenic changes exerted by radiation on the ovarian surface epithelium.

Reforms and supervisory organizations: Lessons from the history of the Istanbul Bourse, 1873-1883

Copyright © 2017 by Emerald Publishing Limited. All rights of reproduction in any form reserved.Inefficiencies in the fiscal and monetary systems of the Ottoman Empire led to a higher debt burden over time and the bankruptcy for the Ottoman state in 1875. To deal with these inefficiencies, reforms were implemented: supervisory organizations were established and the gold standard was adopted. How did investors at the Istanbul Bourse view these reforms? We manually collected data on the price of Ottoman government bonds on the Bourse from 1873 to 1883. Using the generalized autoregressive conditional heteroscedasticity (GARCH) methodology, we identify short-run and permanent changes in volatility of bond returns subsequent to the reforms. Our results suggest investors responded positively, by accepting lower yield premia, to adoption of the gold standard, and foundation of the Ottoman Public Debt Administration which had European sponsors, but did not respond positively to reforms that relied on purely local institutions
