    The Women in IT (WINIT) project was funded by the European Social Fund (ESF) from March 2004 until April 2006 under HE ESF Objective 3: Research into equal opportunities in the labour market. Specifically the project came under Policy Field 2, Measure 2: Gender discrimination in employment. The project was run in the Information Systems Institute of the University of Salford. One of the Research Associates has an information systems (IS) background, the other has a background in sociology. We begin this report with an overview of the current situation with regards women in the UK IT sector. Whilst gender is only recently being recognised as an issue within the mainstream IS academic community, thirty years of female under-representation in the ICT field in more general terms has received more attention from academics, industry and government agencies alike. Numerous research projects and centres (such as the UK Resource Centre for Women in Science, Engineering and Technology) exist to tackle the under-representation of women in SET careers, although the figures for women’s participation in the ICT sector remain disheartening, with current estimates standing at around 15% (EOC 2004). Various innovative initiatives, such as e-Skills’ Computer Clubs for Girls, appear to have had little impact on these low female participation rates. Additionally, these and other initiatives have been interpreted as a means to fill the skills gap and ‘make up the numbers’ to boost the UK economy (French and Richardson 2005), resulting in ‘add more women and stir’ solutions to the ‘problem’ of gender in relation to inclusion in IS and ICT (Henwood 1996). Given that there have been decades of equal opportunity and related policies as well as many government initiatives designed to address the gender imbalance in IT employment patterns, sex segregation in IT occupations and pay and progression disparity in the IT sector (including the latest initiative- a one million pound DTI funded gender and SET project), we could be forgiven for assuming that these initiatives have had a beneficial effect on the position and number of women in the IT workforce, and that even if we have not yet achieved gender equity, we can surely argue that there are positive moves in the right direction. Although we do not wish to make definitive claims about the success or failure of specific initiatives, our research, backed up by recent major surveys, paints a picture that remains far from rosy. Indeed a recent comparative survey of the IT workforce in Germany, Holland and the UK indicates that women are haemorrhaging out of the UK IT workforce (Platman and Taylor 2004). From a high point of 100,892 women in the UK IT workforce in 1999, Platman and Taylor (ibid., 8) report a drop to 53,759 by 2003. As the IT industry was moving into recession anyway, the number of men in the industry has also declined, but by nothing like as much, so the figures for women are stark. When it comes to number crunching who is employed in the UK IT sector and when trying to make historical comparisons, the first obstacle is defining the sector itself. Studies vary quite substantially in the number of IT workers quoted suggesting there is quite a bit of variation in what is taken to be an IT job. The IT industry has experienced considerable expansion over the past twenty years. In spring 2003 in Britain, it was estimated that almost 900,000 people worked in ICT firms, and there were over 1 million ICT workers, filling ICT roles in any sector (e-Skills UK, 2003). This growth has resulted in talk of a ‘skills shortage’ requiring the ‘maximization’ of the workforce to its full potential: ‘You don’t just need pale, male, stale guys in the boardroom but a diversity of views’ (Stone 2004). In spring 2003 the Equal Opportunities Commission estimated there to be 151,000 women working in ICT occupations compared with 834,000 men (clearly using a different, much wider job definition from that of Platman and Taylor (2004)) , whilst in the childcare sector, there were less than 10,000 men working in these occupations, compared with 297,000 women (EOC 2004). It is estimated that the overall proportion of women working in ICT occupations is 15% (EOC 2004). In the UK, Office of National Statistics (ONS) statistics indicate that women accounted for 30% of IT operations technicians, but a mere 15% of ICT Managers and only 11% of IT strategy and planning professionals (EOC 2004). Although women are making inroads into technical and senior professions there remains a ‘feminisation’ of lower level jobs, with a female majority in operator and clerical roles and a female minority in technical and managerial roles (APC 2004).

    Global aspects of accelerating and rotating black hole space-times

    Full text link
    The complete family of exact solutions representing accelerating and rotating black holes with possible electromagnetic charges and a NUT parameter is known in terms of a modified Plebanski-Demianski metric. This demonstrates the singularity and horizon structure of the sources but not that the complete space-time describes two causally separated black holes. To demonstrate this property, the metric is first cast in the Weyl-Lewis-Papapetrou form. After extending this up to the acceleration horizon, it is then transformed to the boost-rotation-symmetric form in which the global properties of the solution are manifest. The physical interpretation of these solutions is thus clarified.Comment: 15 pages, 1 figure. To appear in Class. Quantum Gra

    The C-metric as a colliding plane wave space-time

    Get PDF
    It is explicitly shown that part of the C-metric space-time inside the black hole horizon may be interpreted as the interaction region of two colliding plane waves with aligned linear polarization, provided the rotational coordinate is replaced by a linear one. This is a one-parameter generalization of the degenerate Ferrari-Ibanez solution in which the focussing singularity is a Cauchy horizon rather than a curvature singularity.Comment: 6 pages.

    Health systems analysis of eye care services in Zambia: evaluating progress towards VISION 2020 goals.

    Get PDF
    BACKGROUND: VISION 2020 is a global initiative launched in 1999 to eliminate avoidable blindness by 2020. The objective of this study was to undertake a situation analysis of the Zambian eye health system and assess VISION 2020 process indicators on human resources, equipment and infrastructure. METHODS: All eye health care providers were surveyed to determine location, financing sources, human resources and equipment. Key informants were interviewed regarding levels of service provision, management and leadership in the sector. Policy papers were reviewed. A health system dynamics framework was used to analyse findings. RESULTS: During 2011, 74 facilities provided eye care in Zambia; 39% were public, 37% private for-profit and 24% owned by Non-Governmental Organizations. Private facilities were solely located in major cities. A total of 191 people worked in eye care; 18 of these were ophthalmologists and eight cataract surgeons, equivalent to 0.34 and 0.15 per 250,000 population, respectively. VISION 2020 targets for inpatient beds and surgical theatres were met in six out of nine provinces, but human resources and spectacles manufacturing workshops were below target in every province. Inequalities in service provision between urban and rural areas were substantial. CONCLUSION: Shortage and maldistribution of human resources, lack of routine monitoring and inadequate financing mechanisms are the root causes of underperformance in the Zambian eye health system, which hinder the ability to achieve the VISION 2020 goals. We recommend that all VISION 2020 process indicators are evaluated simultaneously as these are not individually useful for monitoring progress

    Aim: To compare the vertical fusional amplitudes in isometropic participants with normal binocular single vision at four distances of fixation: 33 cm, 1 m, 4 m, 6 m. Methods: Vertical fusion ranges (break point and recovery point) were measured with a Gulden vertical prism bar with the participant fixing a 6/12 Snellen equivalent letter, twice at each distance. Order effects were controlled with randomisation of both fixation distance and prism direction. Results: Twenty-seven participants were examined (aged 20.4 ± 1.05 years). Base up and base down measurements were similar, therefore measurements were combined to give a total vertical range. Median values for the break points were: 33 cm, 6(Δ) ; 1 m, 6(Δ); 4 m, 5.5(Δ); 6 m, 5.5(Δ); and for the recovery points were: 33 cm, 4(Δ); 1 m, 4(Δ); 4 m, 3.5(Δ); 6 m, 3.5(Δ). The difference was significant between either of the near measures (i.e. 33 cm and 1 m) and either of the far measures (i.e. 4 m and 6 m). Conclusions: The vertical fusion range appears to be slightly greater at near than distance. However, the difference is not clinically significant. Measurements for distance, in a normal population, appear to be the same whether a fixation distance of 4 m or 6 m is used

    More than just friends? Facebook, disclosive ethics and the morality of technology

    Get PDF
    Social networking sites have become increasingly popular destinations for people wishing to chat, play games, make new friends or simply stay in touch. Furthermore, many organizations have been quick to grasp the potential they offer for marketing, recruitment and economic activities. Nevertheless, counterclaims depict such spaces as arenas where deception, social grooming and the posting of defamatory content flourish. Much research in this area has focused on the ends to which people deploy the technology, and the consequences arising, with a view to making policy recommendations and ethical interventions. In this paper, we argue that tracing where morality lies is more complex than these efforts suggest. Using the case of a popular social networking site, and concepts about the morality of technology, we disclose the ethics of Facebook as diffuse and multiple. In our conclusions we provide some reflections on the possibilities for action in light of this disclosure

    Image charge effects in single-molecule junctions: Breaking of symmetries and negative differential resistance in a benzene transistor

    Get PDF
    Both experiments and theoretical studies have demonstrated that the interaction between the current carrying electrons and the induced polarization charge in single-molecule junctions leads to a strong renormalization of molecular charging energies. However, the effect on electronic excitations and molecular symmetries remain unclear. Using a theoretical framework developed for semiconductor nanostructure based single-electron transistors (SETs), we demonstrate that the image charge interaction breaks the molecular symmetries in a benzene based single-molecule transistor operating in the Coulomb blockade regime. This results in the appearance of a so-called blocking state, which gives rise to negative differential resistance (NDR). We show that the appearance of NDR and its magnitude in the symmetry-broken benzene SET depends in a complicated way on the interplay between the many-body matrix elements, the lead tunnel coupling asymmetry, and the bias polarity. In particular, the current reducing property of the blocking state causing the NDR, is shown to vanish under strongly asymmetric tunnel couplings, when the molecule is coupled stronger to the drain electrode. The calculated IV characteristic may serve as an indicator for image charge broken molecular symmetries in experimental situations.Comment: Accepted version (Phys. Rev. B), 16 pages, 8 figure

    Editada en la Fundación Empresa PúblicaLa industria textil británica continúa en el centro del debate sobre la revolución industrial. Las innovaciones técnicas en el período produjeron una aceleración extraordinaria del crecimiento del output y una considerable reducción de los precios de los tejidos. En este trabajo presentamos un estudio de la comunidad de los inventores responsables de la transformación tecnológica, lo que nos permite alcanzar una serie de conclusiones nuevas sobre el ritmo y dirección de la actividad innovadora durante la revolución industrialThe cotton textile industry remains central to all accounts of the first industrial revolution. Innovations in this period precipitated an extraordinary acceleration in the growth of output and a steep decline in the cost of producing all varieties of cloth. In this paper we outline an explanation through an analysis of the community of inventors responsible for the technological transformation, which enables us to offer some generalizations of the pace and pattern of the inventive activity in this period.Publicad
