    Leading ladies: discursive constructions of women leaders in the UK media

    Feminist Media Studies, no. Published online: 10 July 2019

    2019

    DOI: 10.1080/14680777.2019.1640266

    Abstract anzeigen

    Women continue to be economically disadvantaged and under-represented in positions of power and leadership. A discursive disjunction between cultural and media representations of women and leadership has been implicated in these continuing inequalities. We address this issue through an analysis of the ways in which prominent women leaders were portrayed in a UK radio series, BBC Radio 4’s “Profile” broadcast between July 2011 and July 2013. Verbatim transcripts of 12 broadcasts featuring women were analysed within a critical feminist framework, to explore the ways in which these women leaders were discursively constructed. Our analysis explicates three constructions of “women leaders”: as “traditionally” feminine; as having to balance “masculine” and “feminine” attributes; and as exceptional women who may nevertheless fail. We conclude that the impact of equality legislation continues to be limited while androcentric norms prevail and that we therefore need more gynocentric ways of imagining women leaders.

    How can historical cultural assets be made accessible and experienced with the help of digital media? Scientists in the Bavarian-Bohemian border region are dealing with this question in the context of the Peregrinus Silva Bohemica project. Historic sites and buildings are made available for all devices. Interesting facts about the monuments are digitally reworked, interpreted and made clear, for example with the help of specially constructed 3D representations or augmented reality (AR).

    Union membership and employment dynamics: The role of the union objective function

    Theoretical Economics Letters, vol. 9, no. 5, pp. 1473-1479

    2019

    DOI: 10.4236/tel.2019.95094

    Abstract anzeigen

    This paper studies the behaviour of a labour union in a model with employment and membership dynamics. It is known from the literature that the relative level of employment between intertemporal and static union models is affected by the structure of the union density function. We show that this result does not hold in general but rather that it depends on the union objective function. If the union maximises the wage bill of their members, employment in the intertemporal model will differ from employment in the static model depending on the union density function. However, if the union maximises the rent from unionisation, the intertemporal model will yield the same level of employment as the static model regardless of the union density.

    Hacking an optics manufacturing machine: You don't see it coming?!

    Proceedings of SPIE 11171 (Sixth European Seminar on Precision Optics Manufacturing, 1117101 [April 9th-10th 2019, Teisnach]), Bellingham, WA, USA

    Abstract anzeigen

    With more and more industrial devices getting inter-connected the attack surface for cyber attacks is increasing steadily. In this paper the possible approach of an attacker who got access to the office network at the Institute for Precision Manufacturing and High-Frequency Technology (IPH) to attack one of the optic machines that reside in another network segment is presented. Based on known vulnerabilities from the Common Vulnerabilities and Exposures (CVE), like the shellshock exploit or remote code execution with PsExec, for devices identified in the network, an attacker can bypass the firewall between the office network and the laboratory network and get full access to the HMI of the target machine.

    This research is focused on the link between manufacturing parameters and the resulting mid-spatial frequency error in the manufacturing process of precision optics. This third publication focuses on strategies of avoidance and generation mechanisms of the mid-spatial frequency errors from the grinding process. The Goal is to understand the generation mechanisms of the mid-spatial frequency errors and avoid their appearance in the manufacturing process.

    Alignment and thermal drift aspects of a four-tilted-mirror student project telescope

    Abstract anzeigen

    The Deggendorf Institute of Technology (DIT) and its Faculty of Applied Natural Sciences and Industrial engineering transfer a broad spectrum of knowledge to the students. The clarification of the interrelations that exist between seemingly isolated fields of knowledge is a permanent process. In order to put this into practice, a telescope construction project was started. The base of the in-house student project is the Technology Campus in Teisnach, which bundles capacities for process development, production and measurement of high-precision optics, including telescope optics. A first optical design, which is based on a subset of the parameter space published in 1989 by M. Brunn1, 2 (later built by D. Stevick as f/12-system3 ), made use of a primary mirror M1 with a diameter of 400 mm. An f/8-system provide a Strehl ratio SR ≥ 0.8 over an entire field of view of 0.7° deg. Even if this seems to be sufficient, manufacturing tolerances, adjustment tolerances, thermal drift and positional changes considerably reduce the Strehl ratio. In order to obtain reliable values of acceptable tolerances, statistical Monte Carlo analyses had been carried out. As consequences, the tube design was changed and the design of new mirror mounts started. This was done to achieve the required stiffness. The new tube designs, one based on carbon-fiber-reinforced polymer (CFRP) and one based on FeNi36, had been tested by using FEM analysis. In addition, the practicability of deep learning based aberration detection was tested. Zernike polynomials obtained by analyzing the star images with a Convolutional Neuronal Network (CNN). The current state of the development is described.

    Wave front sensing for metrology by using optical filter

    Proceedings of SPIE 11171 (Sixth European Seminar on Precision Optics Manufacturing, 1117101 [April 9th-10th 2019, Teisnach]), Bellingham, WA, USA

    Abstract anzeigen

    An interferometric problem is the limited fringe density, which is due to the limited allowed slope difference of superimposed wave fronts. Thus, the angular dynamic range of measurable surfaces and objects under test is limited. In other words, all shapes that deviate from a plane surface or a sphere represent a measuring problem in interferometers, or require an individually adapted null optics, which might cost e.g. 10 k∈ or more. In addition, ground surfaces cannot be measured in standard interferometers, except by using Speckle interferometry, which is limited in resolution. Freeform optics are very problematic. Even when polished, only tactile or confocal coordinate measurement might work. Several interferometers address the problem of the angular deviation to a sphere. For instance, lateral stitching on a curved surface, which is equivalent to the best-fit sphere, or longitudinal stitching is used. To use a tilted wave interferometer for asphere metrology is another option, which provides versatile measurement configurations. The approach discussed here is to use optical filters. The development of this technique is part of a project most recently started at the Technology Campus in Teisnach. The surface under test (SUT) is imaged onto an optical filter, which has a calibrated angular selectivity. Thus, the angles of the local wave front normal vectors are transferred into an intensity distribution. A set of angular measurements enables reduced uncertainty of the wave front measurement. Aspects as e.g. the working principle, boundary conditions and the identification of practical filters are discussed in the paper.
