Ethics and the Evolving Deployments of Disciplinary Practices: A Foucauldian Analysis of the Glamorization of Bodies
The paper discusses how individuals are constituted by disciplinary practices as presented in Michel Foucault’s two major works: Discipline and Punish and The History of Sexuality, Volume 1: An Introduction. The workings of power-knowledge gave rise to the penal apparatus and deployments of sexuality, which affected entire populations. But even as these disciplinary practices evolve and become seemingly more humane and liberating, they continue to produce docile and normalized subjects. One particular example of this process, discussed here in detail, is the transition from the figure of the hysterical woman to the modern glamorous (beautiful) woman. Such a transition extends Foucault’s ideas to show the immense variety of disciplinary practices. The last section explores a Foucauldian conception of ethics that seeks to reclaim the autonomy of subjects through self-creation.Keywords Disciplinarity, governmentality, sexuality, subjectivity,ethics, askēsi
BROCCOLI: overlapping and outlier-robust biclustering through proximal stochastic gradient descent
Matrix tri-factorization subject to binary constraints is a versatile and powerful framework for the simultaneous clustering of observations and features, also known as biclustering. Applications for biclustering encompass the clustering of high-dimensional data and explorative data mining, where the selection of the most important features is relevant. Unfortunately, due to the lack of suitable methods for the optimization subject to binary constraints, the powerful framework of biclustering is typically constrained to clusterings which partition the set of observations or features. As a result, overlap between clusters cannot be modelled and every item, even outliers in the data, have to be assigned to exactly one cluster. In this paper we propose Broccoli, an optimization scheme for matrix factorization subject to binary constraints, which is based on the theoretically well-founded optimization scheme of proximal stochastic gradient descent. Thereby, we do not impose any restrictions on the obtained clusters. Our experimental evaluation, performed on both synthetic and real-world data, and against 6 competitor algorithms, show reliable and competitive performance, even in presence of a high amount of noise in the data. Moreover, a qualitative analysis of the identified clusters shows that Broccoli may provide meaningful and interpretable clustering structures
Muslim Diaspora in the West and International HRM
Interest in Islam and how Muslims organise themselves within the so-called Western
world has largely stemmed from the flow of Muslim immigration since the 1960s and the
1970s (Loobuyck, Debeer, & Meier, 2013). Many of these immigrants have come to these
new lands in the hope of making a better life for themselves economically, or to escape
the political or religious pressures of their homeland (Lebl, 2014). Initially, deeming the
influx of these foreigners to be largely irrelevant, there was little interest in their presence
by the different governments across many jurisdictions. Typically, scant interest was shown
towards entering into dialogue with the Muslim immigrant community. Indeed, until the
1990s, it was not uncommon for Islam to be perceived as a strange, foreign religion that
was best managed through outsourcing to respective consulates (Loobuyck et al., 2013).
Yet, migration and work-based mobility has a significant influence on the world of work
and societies in which organisations are embedded. Many individuals migrate for better
employment perspectives, as well as due to chain migration, betterment in the quality of life
and based on fleeing famine, war and terror zones globally (Sharma & Reimer-Kirkham,
2015; Valiūnienė, 2016). Migration could involve upward as well as downward mobility/
wages, depending on the country and organisation. For example, minimum wages differ
from € 184 in Bulgaria up to € 1923 in Luxembourg (Valiūnienė, 2016). Migration also
contributes to the lived religion of diasporic communities as they navigate their faith at
work (Sharma & Reimer-Kirkha
Reduced combustion mechanism for fire with light alcohols
The need for sustainable energy has incentivized the use of alternative fuels such as light alcohols. In this work, reduced chemistry mechanisms for the prediction of fires (pool fire, tank fire, and flash fire) for two primary alcohols—methanol and ethanol—were developed, aiming to integrate the detailed kinetic model into the computational fluid dynamics (CFD) model. The model accommodates either the pure reactants and products or other intermediates, including soot precursors (C2H2, C2H4, and C3H3 ), which were identified via sensitivity and reaction path analyses. The developed reduced mechanism was adopted to predict the burning behavior in a 3D domain and for the estimation of the product distribution. The agreement between the experimental data from the literature and estimations resulting from the analysis performed in this work demonstrates the successful application of this method for the integration of kinetic mechanisms and CFD models, opening to an accurate evaluation of safety scenarios and allowing for the proper design of storage and transportation systems involving light alcohols
On the prediction of the ignition delay time of bio-syngas
The growing energy demand and more stringent environmental regulations have raised concerns about the production and use of alternative fuels. Due to the potential application of the resulting gaseous streams in turbines as an energy source, slow pyrolysis of biomass including municipal waste have been extensively studied under various situations and atmospheric conditions. Nevertheless, the combustion characteristics of these complex mixtures and the chemical interactions between their constituent species are still not fully understood. Hence, the accuracy of commonly used empirical-based mixing rules for the estimation of the overall reactivity, such as laminar burning velocity and ignition delay time is inefficient. This work is addressed to the numerical prediction of the Ignition Delay Time, IDT, of bio-syngas mixtures at different fuel compositions, stoichiometries, temperature, and pressure, by means of a detailed kinetic model. A simplified tool for preliminary evaluation of the overall reactivity with respect to the above-mentioned conditions was proposed for these mixtures, as well, providing an effective feature for safety and management evaluations
Alternative splicing in lung cancer
Abstract: Alterations in alternative splicing affect essential biologic
processes and are the basis for a number of pathologic conditions,
including cancer. In this review we will summarize the evidence
supporting the relevance of alternative splicing in lung cancer. An
example that illustrates this relevance is the altered balance between
Bcl-xL and Bcl-xS, two splice variants of the apoptosis regulator
Bcl-x. Splice modifications in cancer-related genes can be associated
with modifications either in cis-acting splicing regulatory sequences
or in trans-acting splicing factors. In fact, lung tumors show abnormal
expression of splicing regulators such as ASF/SF2 or some
members of the heterogeneous nuclear ribonucleoprotein family.
The potential significance of alternative splicing as a target for lung
cancer diagnosis or treatment will also be discussed
Prévalence de l’hypotension orthostatique et ses facteurs favorisants chez les hypertendus noirs africains traités
Introduction: Le but de cette étude était de déterminer la prévalence de l’hypotension orthostatique (HO) chez les hypertendus noirs africains traités, et rechercher ses facteurs favorisants. Méthodes: Il s’est agi d’une étude prospective transversale menée du 1er février 2007 au 31 janvier 2009 à la clinique cardiologique du CHU Campus de Lomé, incluant des patients régulièrement traités pour hypertension artérielle. La pression artérielle et la fréquence cardiaque étaient mesurées en décubitus dorsal puis immédiatement en orthostatisme (1ère et 3ème minutes). Résultats: Sur une population de 394 patients hypertendus traités, 81 cas d’HO (20,5 %) ont été observés dont 53 (65,4 %) étaient symptomatiques. Il s’agissait de 188 femmes (49,2%) et de 206 hommes (50,8%). L’âge moyen des hypertendus était de 53,4 ans ± 11,2 avec des extrêmes de 26 ans et de 81ans. Les patients ayant présenté une HO avaient un âge moyen significativement plus élevé : 60 ans contre 51 ans chez les autres (p= 0,01). L’HO était plus fréquente chez les patients traités par antihypertenseurs centraux, les patients ayant présenté un accident vasculaire cérébral, les diabétiques, les obèses. Conclusion: L’hypotension orthostatique est fréquente chez les hypertendus noirs africains traités. Il faut la rechercher systématiquement chez tous les hypertendus surtout mal contrôlés car elle peut être non seulement un facteur de mauvaise observance thérapeutique, mais aussi un facteur de risque cardiovasculaire indépendant
Non-Steroidal Anti-Inflammatory Drugs in the Carcinogenesisof the Gastrointestinal Tract
It is estimated that underlying infections and inflammatory responses are linked to 15–20% of all deaths from cancer worldwide. Inflammation is a physiologic process in response to tissue damage resulting from microbial pathogen infection, chemical irritation, and/or wounding. Tissues injured throughout the recruitment of inflammatory cells such as
macrophages and neutrophils, generate a great amount of growth factors, cytokines, and reactive oxygen and nitrogen species that may cause DNA damage that in turn predisposes
to the transformation from chronic inflammation to neoplasia. Cyclooxygenase (COX), playing a key role in cell homeostasis, angiogenesis and tumourigenesis, may represent the link between inflammation and cancer. Currently COX is becoming a pharmacological target for cancer prevention and treatment
Effects of atmospheric conditions on surface diffuse degassing
International audienceDiffuse degassing through the soil is commonly observed in volcanic areas and monitoring of carbon dioxide flux at the surface can provide a safe and effective way to infer the state of activity of the volcanic system. Continuous measurement stations are often installed on active volcanoes such as Furnas (Azores archipelago), which features low temperature fumaroles, hot and cold CO2 rich springs, and several diffuse degassing areas. As in other volcanoes, fluxes measured at Furnas are often correlated with environmental variables, such as air temperature or barometric pressure, with daily and seasonal cycles that become more evident when gas emission is low. In this work, we study how changes in air temperature and barometric pressure may affect the gas emission through the soil. The TOUGH2 geothermal simulator was used to simulate the gas propagation through the soil as a function of fluctuating atmospheric conditions. Then, a dual parameters study was performed to assess how the rock permeability and the gas source properties affect the resulting fluxes. Numerical results are in good agreement with the observed data at Furnas, and show that atmospheric variables may cause the observed daily cycles in CO2 fluxes. The observed changes depend on soil permeability and on the pressure driving the upward flux
