Government policy and corporate strategy in managing risk and uncertainty on technology deployment and development in the regulated market in the UK - a study of biofuels
Full text linkTechnological change when a large social technology is under the processes of
deployment and development are complex and uncertain. In this dynamic context,
risks and uncertainties (R&U) incurred are unavoidable, which might obstruct the
progression of the technology implementation and innovation. Hence, a set of
mechanism and strategy are required from the stakeholders to facilitate these two
processes and to deal with R&U arise. This research studied biofuels in the UK by
looking at the context of a regulated market. The Scottish Government and two oil
companies (BP and Shell) were selected as cases studied. Subsequently, an
overarching research question was formulated to drive the research “How these
major actors interact with one and another to deal with R&U arising from
technological change during a technology deployment and development?” By using
Social Shaping of Technology (SST), integrating with Risk Governance and the Risk
Regulated Regime; an interdisciplinary concept has been developed. The application
of SST was to broaden the risk governance and risk regulated regime, helped to look
at R&U of technological change from a social dimension. The research was
grounded on social constructionism under an exploratory study. A qualitative case
study approach was adopted, backed by three data collection methods-interview,
observation and document analysis. This research was aimed to investigate the
driving forces for the government and oil companies in taking biofuels as the current
energy source for transport; their roles and responsibilities in biofuels deployment
and development; interactions taken place, R&U faced during two processes, as well
as counteracting strategy implemented to deal with these R&U. After that,
explanation building and time series analysis were adopted for data analysis. The
research points out there were different types of R&U (expected and unexpected)
arose when a technology undergoes the processes of technological change. These
different types of R&U required different strategies to deal with. Therefore, the
regulators have to set a clear direction for a technology deployment and
development, as well as to have the control mechanism with precautionary principle
instituted, in order to facilitate the technology implementation and innovation.
Meanwhile, oil companies are collaborating with the governments, to commit
consistent biofuels supply which fulfil the requirements set by the regulators; as well
as established various types of partnership with biotechnology institutions/agriculture
industry to conduct the next generation biofuels (NBG) R&D. Such seamless
interactions and cooperation, not only aim to reduce the possibilities of R&U
occurrence, to minimise the impacts, but also to set a path for the ease of technology
adoption and innovation. Therefore, apart from satisfying their respective internal
interests of political and economic gains; these two actors have to safeguard the
social, economic and environmental benefits for the interests of the general public
TRANSITION OF THE ENGINE POWERED AIR-CONDITIONING SYSTEM TO THE SOLAR POWERED AIR-CONDITIONG SYSTEM IN A BUS: A FEASIBILITY STUDY
Full text linkDeveloping and generating a better way of the fossil fuel exertion is necessary in today’s transportation technology. Fossil fuels are of great importance in transport systems because they can be burned and producing significant amounts of energy to move the vehicle along. Generally usage of the air-conditioning system in the transportation will increase the usage of the fossil fuel, since the fuel is used to power the air-conditioning system, as well as to power the movement of the vehicle. The additional energy resource such as solar can be used in a vehicle to generate adequate energy to power the air-conditioning system. The research was grounded on an exploratory study. A qualitative case study approach was adopted. The data collected was analyzed to get the most efficient way to install the solar panel on a roof top of a bus. As the conclusion, the solar application will be benefit to a bus. The consumption of the fossil fuel is lowered and the efficiency of the engine is enhanced since the energy input is maximizing for the movement of the bus alone. Besides, this application also benefits to the environment as it produces lower carbon
Methods for treating construction waste as resources from a sustainable development perspective
No full textThe amount of new construction and demolition activities of building projects has reached an unprecedented level, and the resulting construction waste has a significant impact on the country's society and economy. In this study, a dynamic material flow model of construction waste is proposed. The area estimation method is introduced to calculate the production of three kinds of construction waste. The relationship between construction waste flow and building stock is determined, and the impact of different waste treatment technologies on the environment is quantified by coupling relationship. The results show that the output of waste concrete, brick, wood and steel will reach the maximum in 2049. Acid rain and global warming caused by two treatment methods of construction waste steel and building waste wood are more serious
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Benchmarking Key Success Factors for the Future Green Airline Industry
No full textAbstractThe airline industry is one of the fastest growing industries as well as transportation modes in the world. Global airline contributes about 2% of global greenhouse gas emissions and supports 8% of the world economic activity in terms of GDP. Along with the rapid growth of the airline service industry, climate change issue is getting more attention due to its increasing adverse effects on human and earth. Competing and winning in today's economy required a strategy that incorporates environment sustainability. In recent decades, airlines and aircraft manufacturers have become increasingly committed to becoming more “green,” or environmentally friendly. To close the gaps, a research has been done in order to eliminate as much potential harm to the environment as possible and make air travel as efficient and economical as it can be by identifying the key success factors toward Green Airlines. A research was conducted based on the secondary data from the Green Airlines international data sample to provide airlines and aircraft operators a common framework for identifying and implementing practical and measurable processes, innovative practices, and operations. The operation of Green Airlines only focuses from gate to gate destination with giving impact on the customer experience on the services. Through the benchmarking for high performing green airlines, a green airline framework can be a solution for future Green Airline Industry. The research highlights and demonstrates the need for a degree of understanding of key success factors when comparing airline performance measures with each other
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
