Review of: Markus Gamper: Islamischer Feminismus in Deutschland? Religiosität, Identität und Gender in muslimischen Frauenvereinen. Bielefeld: transcript Verlag 2011.
No full textAnhand von qualitativen und quantitativen Daten wird in dieser soziologischen Studie die Bedeutung von Religiosität, Identität und Gender in muslimischen Frauenvereinen in Deutschland untersucht. Markus Gamper verknüpft die Ergebnisse mit den kulturtheoretischen Ansätzen von Stuart Hall und Homi K. Bhabha und vertritt die These, dass ein islamischer Feminismus in Deutschland existiere. Er stellt fest, dass es den in den Vereinen organisierten Frauen gelinge, Gegendiskurse zu der deutschen Mehrheitsgesellschaft sowie zu den androzentrisch geprägten muslimischen Gemeinschaften zu entwickeln und somit Widerstand gegen Diskriminierung zu leisten. Der Autor begegnet in den von ihm untersuchten Vereinen – statt ‚unterdrückten Muslima‘, wie sie von den Medien inszeniert werden – hochgebildeten Frauen, die selbstbewusst und unabhängig ein religiöses Leben führen.Using qualitative and quantitative data, this sociological study analyzes the meaning of religiosity, identity, and gender in Muslim women’s societies in Germany. Markus Gamper connects the findings to approaches from the field of cultural theory by Stuart Hall and Homi K. Bhabha. Furthermore, he advocates the proposition that Islamic feminism exists in Germany. He states that the women who are organized in these societies succeed in developing counter discourses to German mainstream society as well as to the androcentrically coined Muslim communities, thus, making a stand against discrimination. In the analyzed societies, the author encounters – instead of “suppressed Muslim women” as they are presented by the media – highly educated women, who, confidently and independently, lead a religious life
On a Loophole in Causal Closure
No full textStandard definitions of causal closure focus on where the causes in question are. In this paper, the focus is changed to where they are not. Causal closure is linked to the principle that no cause of another universe causes an event in a particular universe. This view permits the one universe to be affected by the other via an interface. An interface between universes can be seen as a domain that violates the suggested account of causal closure, suggesting a view in which universes are causally closed whereas interfaces are not. On this basis, universes are not affected by other universes directly but rather indirectly. © 2017 The Author(s)</p
Determination of the shear strength of tropical hardwood timber
No full textThe current shear strength values for high density tropical hardwoods are very low compared to the values for softwoods, according to European strength class tables. The reason for this is that standardized tests according to European standard EN 408 have not been performed yet for tropical hardwoods. In this research, tropical hardwood species massaranduba was investigated according to EN 408. The test results give a 5%-value for the shear strength of massaranduba that is twice as high as the standardized value for strength class D70. No relation was found between the density and the shear strength for massaranduba. Shear strength was proportional to the density when compared to spruce. Steel & Composite Structure
The Austrian Constitutional Convention: continuing the path to reform the Federal State
No full textAquest article tracta els diferents debats i intents de reforma del sistema federal austríac dels darrers quinze anys. L’article parteix d'una perspectiva històrica que descriu els desenvolupaments més rellevants del federalisme austríac en el decurs del segle XX, i destaca la importància del procés de centralització a través de la constant transferència de competències des dels Länder al Govern federal, així com els diversos debats en aquest sentit. Segons l’autora, des de 1995, any de l’accés d’Àustria a la Unió Europea, s’han perdut dues grans oportunitats per dur a terme una reforma general del sistema federal que pogués contribuir a compensar el procés de centralització. La primera oportunitat perduda té referència directa amb la Unió Europea. Els Länder van accedir a l’adhesió amb la condició que la Constitució federal preveiés des de diverses dimensions la seva participació en els processos europeus de presa de decisions, tot deixant de banda l’oportunitat d’aprofitar el debat i pressionar per a una reforma estructural del sistema federal. La segona oportunitat perduda té a veure amb la dispersió de propostes resultants dels treballs de la Convenció Constitucional Austríaca. La Convenció, creada el 2003, tenia la missió de discutir la reforma de la Constitució en els aspectes que regulen l’estructura federal del país i, en conseqüència, elaborar- ne un primer esborrany. La incapacitat d’establir i definir eixos comuns de reforma, juntament amb la manca de flexibilitat i de cerca de compromís polític, van desdibuixar el paper de la Convenció.This article discusses the different debates and attempts to reform the Austrian federal system over the last fifteen years. The article is based on a historical perspective that describes the most relevant developments of Austrian federalism during the 20th century, highlighting the importance of the centralisation process through the constant transfer of powers from the Länder to the Federal Government, as well as various debates in this regard. According to the author, since 1995, the year of Austrian adhesion to the European Union, two opportunities have been missed to carry out a general reform of the federal system which could contribute to compensating the centralisation process. The first missed opportunity is directly related to the Austrian adhesion to the European Union. The Länder agreed to the adhesion under the condition that the Federal Constitution would include their participation in European decision-making processes. By focussing on this point, the Länder set aside the opportunity to take advantage of the debate and, as a consequence, press for structural reform of the federal system. The second missed opportunity was related to the dispersion of proposals resulting from the work of the Austrian Constitutional Convention. The Convention, created in 2003, had the mission of discussing those aspects of the reform of the Constitution that regulated the federal structure of the country and, as a consequence, of making a first draft reform. The incapability of establishing and defining common ground for reform, together with the lack of flexibility and of seeking political commitment, weakened the role of the Convention and, thus, any possibility to carry on with the reform
Essays in empirical environmental economics : GIS-econometric analysis of Indonesia's fires, Bolivia's deforestation and Mexico's trade with the U.S.
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Economics, 2001.Includes bibliographical references (p. 114-116).This thesis examines three environmental issues in developing countries. The first essay examines land fires in Indonesia that inflict severe air pollution-related damage on Southeast Asia annually. Conservative estimates of losses in 1997 alone were US12 million for Singapore. Fire incidence on various landholdings is examined using a new author-compiled database on satellite-based fire and rainfall data, land use maps, socioeconomic and geographical information. The essay finds that estates, large-scale industrial plantations that are rapidly expanding in the tropics, raise fire incidence beyond the 'natural' level (the fire incidence on conservation areas serves as a benchmark). In contrast, it finds no evidence that small landholdings, which are often blamed for fires, raise fire incidence. The government's ban on the use of clearance fires, as a result of weak enforcement, did not reduce fire incidence on estates. Alternative policy-levers that could potentially reduce these fires, such as lengthening the estates' leases to improve their property security, are found to be ineffective. The second essay examines whether education can potentially reduce households' agricultural-related forest clearance by increasing the returns to wage labor. It analyzes a unique survey of 649 indigenous households in protected areas in Bolivia's lowland forests. It finds that an additional year of education among household heads is associated with a reduction of 0.05 hectares or 4.3% of the annual mean household forest clearance, increased returns of 2.6% in wage labor and a 21 % increase in days worked in wage labor. Thus the 3-year average increase in education among the youngest cohorts is associated with potentially significant reduction in forest clearance in the study site, though further work is needed to establish causality. The third essay examines the pollution intensity of the NAFTA-related expansion in USMexican trade using new detailed measures of air, water, metal and toxic pollution intensities and injury rates at the 4-digit Standard Industrial Classification level. Based on pollution measures at this resolution, it does not find strong evidence of greater growth in the share of US net imports from Mexico in the more polluting or injurious industries.by Shanti Rabindran Gamper.Ph.D
Does industry self-regulation reduce accidents? Responsible care in the chemical sector
No full textThis is the first study to evaluate the impact of self-regulation on industrial accidents. We examine Responsible Care in the US chemical manufacturing sector using our author-constructed database of 1,867 firms that own 2,963 plants between 1988 and 2001. Firms’ self-selection into RC is instrumented using pollution-related regulatory pressure on firms that influences their probability of joining RC, but not plant-level accidents. The average treatment effect on the treated indicates that RC reduces the likelihood of accidents by 2.99 accidents per\ud
100 plants in a given year. This 69.3% reduction in the likelihood of accidents, accounting for the plants that participate in RC, translates to back-of-the-envelope avoided losses of 3.8 billion per year. RC also reduces the likelihood of more narrowly-defined accidents, i.e., process safety accidents and accidents related to violations of RC codes, by 5.75 accidents per 100 plants in a given year or by 85.9%
Adaptive Radiation Survey Using an Autonomous Robot Executing LiDAR Scans in the Large Hadron Collider
No full textAt CERN, radiation surveys of equipment and beam lines are important for safety and analysis throughout the accelerator complex. Radiation measurements are highly dependent on the distance between the sensor and the radiation source. If this distance can be accurately established, the measurements can be used to better understand the radiation levels of the components and can be used for calibration purposes. When surveys are undertaken by the Train Inspection Monorail (TIM) robot, the sensor is at a constant distance from the rail, which means that it is at a known distance and height from the centre of the beam line. However, the distance of the sensor to the closest surface of the beam line varies according to what kind of equipment is installed on the beam line at this point. Ideally, a robotic survey would be completed with online adaption of the sensor position according to the equipment present in the LHC. This new approach establishes a scan of the surface with a 2D LiDAR while moving along the tunnel axis in order to obtain a 3D scan of the environment. This 3D scan will be used to generate online trajectories that will allow the robot to accurately follow the beam line and thus measure the radiation levels.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Human-Robot Interactio
