Attributing scientific and technical progress: the case of holography
Holography, the three-dimensional imaging technology, was portrayed widely as a paradigm
of progress during its decade of explosive expansion 1964–73, and during its subsequent
consolidation for commercial and artistic uses up to the mid 1980s. An unusually
seductive and prolific subject, holography successively spawned scientific insights, putative
applications and new constituencies of practitioners and consumers. Waves of forecasts,
associated with different sponsors and user communities, cast holography as a field on the
verge of success—but with the dimensions of success repeatedly refashioned. This retargeting
of the subject represented a degree of cynical marketeering, but was underpinned by
implicit confidence in philosophical positivism and faith in technological progressivism.
Each of its communities defined success in terms of expansion, and anticipated continual
progressive increase. This paper discusses the contrasting definitions of progress in holography,
and how they were fashioned in changing contexts. Focusing equally on reputed ‘failures’ of some aspects of the subject, it explores the varied attributes by which success and failure were linked with progress by different technical communities. This important case illuminates the peculiar post-World War II environment that melded the military, commercial and popular engagement with scientific and technological subjects, and the
competing criteria by which they assessed the products of science
Making Waves: Media's Potential for Girls in the Global South
There are around 600 million adolescent girls living in developing countries. Doubly marginalised because oftheir gender and age, many live a bleak existence -- excluded from access to basic public services, unable to shape the decisions that affect their lives and vulnerable to violence at home and on the street. Their voices often go unheard.Slowly, this is beginning to change. Over the past two decades girls have become a growing priority for the international development community. Investing in their health education and employment prospects is nowwidely considered to have an important ripple effect on other development outcomes such as economic growth and social equality. As a result, development assistance programmes that support girls' empowerment are now seen by many as not just the "right" thing to do, but a necessity Less well understood is where media fits into this equation The interplay between media and gender norms has long been recognised and a substantial literature explores how media affects girls in the Global North But against a backdrop of rapidly changing media landscapes -- characterised by increasing competition for audiences sensationalism and expanding access to new technologies -- the role that media plays in girls' lives in the Global South demands further examination.Drawing on expert interviews as well as insights from the media and development literature, this policy briefing seeks to fill this gap. It argues that media -- whether traditional or online -- matters a great deal in the lives of girls in the developing world. It matters because it has the ability to be harmful to girls' interests and self-esteem, and it matters because it can also be so effective in playing a positive role in girls' lives. Specifically, media can influence girls' aspirations and behaviours around their health and livelihoods open the door to greater participation in society and ensure that girls' issues move higher up the public agenda. If challenges around media access and control and the extent to which media organisations value girls as part of their audience, are addressed head on, media can play a vital role in helping to advance the wellbeing of adolescent girls in regions of the world where their interests have traditionally been most neglected
Lignocellulosic Ethanol: The Path to Market
The cost effective production of transport fuels from biomass is essential if the EU aspiration to substitute 10% of transport fuels with sustainable alternatives by 2020 is to be met. The hope, voiced by the Parliament’s Industry and Energy Committee, is that at least 40% of the 2020 target will come from second-generation biofuels, and therein lies the challenge: second-generation conversion technologies are not yet commercial. Multiple pathways are being investigated around the globe, but dominant pathways have yet to emerge and business models have yet to be proven. Nevertheless, expectations are running high and there has been significant investment in R&D in the US, Europe and Asia. The production of ethanol from lignocellulosic biomass is commercially and environmentally one of the most promising options, and in 2007 the US Department of Energy (DOE) provided more than US1.33 per gallon, when deployed at scale, by 2012. The majority of studies also suggest that LE will result in superior greenhouse gas savings compared to ethanol produced from starch. Despite favourable predictions for cost and environmental performance, market deployment requires practical and plausible development paths that are able to support progress from existing small-scale demonstration plant to large industrial installations. Moreover, these development paths must be sufficiently attractive to persuade developers and investors that lignocellulosic ethanol remains an opportunity worth pursuing

Academic use of digital resources: Disciplinary differences and the issue of progression revisited
This paper examines the use of digital resources by academic staff in a single UK University and its influence on academic practice over a two to three year period. The paper describes two linked studies that address several of the themes regarding the impact of electronic resources identified in this special edition. In particular it provides findings that contribute to our understanding of changing roles and practices in academic teaching (Oliver this edition). The themes explored in this paper include the way disciplinary differences affect the use of digital resources, and how academic progression is understood by academic staff in different disciplines and its role in informing staff choices in deploying digital resources for student use. The paper also addresses the issue of changing academic practice and the adoption life cycle in relation to use of digital resources.

International Listing as a Means to Mobilize the Benefits of Financial Globalization: Micro-Level Evidence from China
This paper proposes a micro-level framework to account for how firms in developing economies overcome domestic institutional constraints. It illustrates that the mechanisms enabling those firms to benefit from financial globalization are more complex than the “direct” financial channels outlined in the neo-classical approach. China provides an important example in this context, as its capital market liberalization has been limited and neither the legal nor financial system is well developed. Yet micro-level evidence from China’s internationally listed enterprises indicates that innovative firms can overcome institutional thresholds, secure access to international capital, and benefit and learn from international capital markets. This can in turn induce market-level improvements through regulatory competition and demands for a more standardized system of economic regulation
Ethical Governance in the Indian Construction Industry: A Case Study of Larsen & Toubro Ltd.
Governance has moved beyond mere fulfilment of legal requirements. The corporate debacles of the last decade and more have indicated how very respectable corporate organisations across the globe succumbed to greed and compromised on ethics and organisational value systems. Corporate Governance is mainly concerned with the intrinsic nature, purpose, integrity, and identity of an organisation. It encompasses the entire gamut of organisational stakeholders. While a lot of literature is available in the field of Corporate Governance, an analysis of corporate organisations in terms of their stakeholder-related initiatives has hitherto not been attempted. In this paper, the author has used the case study of an Indian multinational corporation — Larsen & Toubro’s Engineering, Construction and Contracts Division (ECC) — and has attempted to study its practices with respect to two major stakeholders: the Shareholder and the Government. ECC is a market leader in the Indian construction industry and has been associated with some of the most prestigious governmental, commercial, and religious construction projects in the country over the last six decades. Triangulation of data has been gathered for this case study primarily through personal interviews with top executives of the Company and responses to an Executive Perception Survey on the Shareholders and the Government. This has been supplemented through other information available in the public domain
Levels of abstraction in human supervisory control teams
This paper aims to report a study into the levels of abstraction hierarchy (LOAH) in two energy distribution teams. The original proposition for the LOAH was that it depicted five levels of system representation, working from functional purpose through to physical form to determine causes of a malfunction, or from physical form to functional purpose to determine the purpose of system function. The LOAH has been widely used throughout human supervisory control research to explain individual behaviour. The research seeks to focus on the application the LOAH to human supervisory control teams in semi-automated “intelligent” systems

Interactive infographics and news values
This is an Author's Accepted Manuscript of an article published in Digital Journalism [PUBLICATION DETAILS], copyright @ Taylor & Francis, available online at http://www.tandfonline.com/10.1080/21670811.2013.841368.This study is concerned with the news values and working practices that inform the creation of interactive infographics in UK online news. The author draws upon organisational theory in journalism studies, and considers how conventional journalistic news values compare with best practice as espoused in different literatures within this field. A series of open-ended, depth interviews with visual news journalists from the UK national media were undertaken, along with a short-term observation case study at a national online news publisher. Journalistic and organisational norms are found to shape the selection, production, and treatment of interactive graphics, and a degree of variation is found to exist amongst practitioners as to definitions of quality in this field. Some news stories are considered to be better suited to rendering in interactive form than others. The availability of “big data” does not drive decision-making in itself, but some numbers are considered more newsworthy than others. Budgetary constraint drives practice and limits potential in this field. Risk aversion, embodied in various forms; from the use of templates, to a perceived need to avoid audience complaint, is found to dampen experimentation. Detailed audience research was found to inform the choice of methods used in data visualisation at one national news producer. This warrants further investigation as to how audiences engage with news interactives, and what the framing of news in certain (preferred) data visualisation formats means in terms of how news is understood
Listening to firms : how to use firm-level surveys to assess constraints on private sector development
Firm-level surveys elicit information important to formulating sound policy advice and designing projects to promote private sector development. Drawing on recent World Bank experience in eight countries, the author advises why and how to implement targeted field surveys by answering the following questions: Why use targeted field surveys? How should surveys be focused and designed? What types of questions work best in surveys? How can surveys be oriented toward their target population? How should surveys be implemented? How should responses be analyzed and used? In this common sense guide, the author emphasizes how a carefully designed and implemented survey helps you get the most from a brief session with an entrepreneur or senior manager. Examples of questions that have been useful in eliciting analytically tractable responses relevant for policy formulation are given. Pitfalls that diminish the value of surveys and bias their results are identified. The author discusses such practical necessities as training and supervising local surveyors, identifying firms, and entering data into an appropriate software package. Finally, he cautions against two extremes: omitting assessments of the private sector or using survey results out of context, and failing to weigh them against other sources of information. Omission is the more serious of the two problems.Environmental Economics&Policies,Social Analysis,Health Monitoring&Evaluation,Public Sector Economics&Finance,Banks&Banking Reform
